In actual processing, because the conveying pipeline is long in conveying distance and narrow in pipeline, and meanwhile, the conveying pipeline is in a closed state, the interior of the conveying pipeline cannot be cleaned, partial impurities such as chips and dust can be generated in the rice hulling process, when the conveying pipeline is used for conveying rice, the impurities can remain in the conveying pipeline, and the normal conveying of the rice can be interfered after the impurities are not cleaned for a long time; meanwhile, in actual processing, different types of rice are processed in the same production line, so when the subsequently processed different types of rice are conveyed by utilizing the conveying pipeline, part of the previously processed rice can be partially remained in the conveying pipeline, in order to remove the previously processed rice remained in the conveying pipeline, the currently adopted method is to directly utilize the subsequently processed different types of rice to carry out ' cleaning ' on the conveying pipeline, namely, the subsequently processed rice is utilized to wash the conveying pipeline to complete the ' cleaning ' on the conveying pipeline, therefore, the currently adopted method mixes the two different types of rice in the ' cleaned ' rice, so that the rice for cleaning ' the conveying pipeline can not be normally sold and can only be used as poultry foodstuff, which causes resource waste to a certain extent, and when the conveying pipeline is currently utilized to carry out ' cleaning ', generally, about half an hour is consumed, and the processing of the rice is influenced due to low cleaning efficiency.

Disclosure of Invention

The invention aims to provide a cleaning method of a rice processing production line, and solves the problem that a conveying pipeline cannot be conveniently and quickly cleaned in the prior art.

In order to achieve the purpose, the invention adopts the following technical scheme: the cleaning method of the rice processing production line adopts the cleaning mechanism to clean the conveying pipeline, the cleaning mechanism comprises an air pressure device, a cleaning medium and an air supply pipeline connected to the air pressure device, a sealing assembly is connected in the air supply pipeline in a rotating mode, an elastic piece is arranged between the sealing assembly and the air supply pipeline, an air supply opening matched with the sealing assembly is formed in the conveying pipeline, and the cleaning method comprises the following steps:

step one, adding a cleaning medium into a wind supply pipeline;

step two, starting the air pressure device, introducing compressed air into the air supply pipeline by the air pressure device, pushing the sealing assembly to rotate from the state of sealing the air supply outlet to the state of blocking the conveying pipeline by the compressed air, and blowing cleaning media into the conveying pipeline by the compressed air to complete cleaning of the conveying pipeline;

and step three, after cleaning is finished, the air pressure device is closed, the sealing assembly rotates to the state of sealing the air supply outlet under the elastic force action of the elastic element, and the conveying pipeline is in a smooth state.

The principle of the scheme is as follows: when the conveying pipeline conveys the rice normally, the sealing assembly rotates to the state of sealing the air supply outlet under the elastic force of the elastic piece, and the conveying pipeline is in a smooth state at the moment and can convey the rice normally; when the conveying pipeline needs to be cleaned, firstly, cleaning medium is added into the air supply pipeline, then the air pressure device is started, compressed air is introduced into the air supply channel by the air pressure device, so that the air pressure in the air supply channel is increased, the sealing assembly rotates under the pressure action of the air pressure, the elastic piece simultaneously elastically deforms, and finally the sealing assembly rotates to a state of blocking the conveying pipeline, at the moment, the cleaning medium is blown into the conveying pipeline by the compressed air in the air supply pipeline through the air supply opening, the cleaning medium and the air flow in the conveying pipeline jointly act to clean the interior of the conveying pipeline, so that impurities, residual rice and the like in the conveying pipeline are removed, when the cleaning is finished, the air pressure in the air supply pipeline stops introducing the compressed air into the air supply pipeline, at the moment, the air pressure in the air supply pipeline is reduced, so that the sealing assembly rotates to the state of the sealed air supply opening under the elastic force of the, at the moment, the conveying pipeline is in a smooth state and can continuously convey the rice, and the air supply opening is sealed by the sealing assembly, so that the rice conveyed in the conveying pipeline cannot enter the air supply pipeline.

The beneficial effect of this scheme lies in:

1. can conveniently and accomplish the washing to pipeline high-efficiently: compared with the prior art in which the conveying pipeline is cleaned by the rice processed subsequently, the cleaning efficiency is low. In this application, utilize the compressed gas that the wind-pressure ware formed to wash pipeline, still can add the cleaning medium in the cleaning process simultaneously, cleaning medium cooperation compressed gas can conveniently carry out the efficient to pipeline and wash when pipeline, washs thoroughly and consuming time less.

2. Can reduce the waste of rice: compare in prior art when utilizing the rice of follow-up processing to carry out "washing" to pipeline, the mixed rice that "washs" produced can't carry out normal selling and cause certain waste. Can reduce the waste of rice when processing different kinds of rice in this application.

3. The use environment is various: the wiper mechanism who sets up in this application can wash impurity etc. in the pipeline when processing same kind of rice, also can utilize wiper mechanism to wash impurity and remaining rice in the pipeline when processing different kinds of rice simultaneously, and abluent environment is various and unrestricted.

4. Simple structure and control are convenient: in this application, when utilizing wiper mechanism to wash pipeline, only need add cleaning medium in the supply air duct, then seal assembly rotates to the state of blocking pipeline automatically under the effect of wind pressure ware to make cleaning medium and compressed gas wash in can entering into transfer passage automatically, wash the completion back, close the wind pressure ware, seal assembly automatic re-setting and make pipeline can continue smoothly to use, whole wiper mechanism's simple structure and control are convenient.

Preferably, as a refinement, the supply air outlet is located in the delivery duct near the discharge end.

In the prior art, in order to enable the conveying pipeline to convey the rice smoothly, the conveying pipeline is usually set to be in an inclined state, the high end of the conveying pipeline is a feeding end, the low end of the conveying pipeline is a discharging end, the processed rice is added into the conveying pipeline through the feeding end, and under the action of self gravity, the rice in the conveying pipeline can automatically slide to the low end and slide out of the conveying pipeline from the discharging end. In this scheme, set up the supply-air outlet in pipeline's discharge end department, after utilizing wiper mechanism to send into cleaning medium and compressed gas in to pipeline, cleaning medium and compressed gas are removed to the high-end by pipeline's low side, because cleaning medium's action of gravity for cleaning medium can be located pipeline for a longer time, thereby makes cleaning medium can with pipeline's inside contact more the pioneer, the cleaning performance who plays is better.

Preferably, as an improvement, the cross section of the conveying pipeline is circular, the sealing assembly comprises a rotating plate and a stop block, the rotating plate is rotatably connected to the junction of the air supply pipeline and the air supply outlet, the stop block is fixedly connected in the air supply pipeline, and the stop block is located on the rotating path of the rotating plate.

In this scheme, through the effect that blocks of dog to the rotor plate, can avoid the rotor plate to rotate to the air supply passageway in to avoid the rice of carrying to get into the air supply passageway in among the transfer passage, in order to prevent that the air supply passageway can't normally work.

Preferably, as an improvement, in the second step, a spiral guide groove is provided on the windward surface of the rotating plate, and the direction of the airflow entering the conveying duct from the air supply duct is along the tangential direction of the conveying duct under the guiding action of the spiral guide groove.

In this scheme, through setting up the spiral guide way, when wasing, the rotor plate rotates to blocking pipeline's state back, spiral guide way on the rotor plate can be to air intake department gas and slope that get into in the pipeline and cut to play the guide effect, thereby make in gas and cleaning medium enter into pipeline along the tangential direction of pipeline inner wall, thereby make gas and cleaning medium can rise along pipeline's inside spiral, make gas and cleaning medium can more fully with pipeline's inner wall contact, thereby play better cleaning performance.

Preferably, as a refinement, in step one, the cleaning medium includes dry ice particles.

In this scheme, under the atmospheric pressure effect in the air supply passageway, make the dry ice granule blown to the pipeline at a high speed in, the momentum change of the dry ice granule of utilizing high-speed motion, sublimation, energy conversion such as melting, make the inside impurity of washing pipeline freeze rapidly, thereby the time impurity condenses, embrittle, by peeling off, and is clear away under the effect of air current, use the dry ice granule simultaneously and can not cause the damage to pipeline's inner wall, and even partly dry ice granule remains in pipeline, wait to wash and also can automatic sublimation gradually and disappear after accomplishing, can not produce to pipeline and block up or mix in the rice and produce the influence by the rice.

Preferably, as an improvement, in the first step, the cleaning medium further includes a cleaning plastic ball, and a plurality of bristles are fixedly connected to an outer wall of the cleaning plastic ball.

According to the scheme, the cleaning plastic balls are arranged, and after the cleaning plastic balls are blown into the conveying pipeline, the bristles on the outer walls of the cleaning plastic balls can scrub the inner wall of the conveying pipeline, so that the inner wall of the conveying pipeline is better cleaned; simultaneously, because washing plastic bag itself occupies certain space, can fill the pipeline inner space after plastics cleaning ball enters into pipeline to make the volume of gas circulation reduce, consequently can make the velocity of flow increase of gas, thereby make pipeline's inside obtain better cleaning performance.

Preferably, as an improvement, the cleaning plastic ball is internally provided with a hollow part which is arranged in a hollow way, and a plurality of steel balls which can freely roll are arranged in the hollow part.

In the scheme, a plurality of steel balls which roll freely are arranged in the hollow part of the cleaning plastic ball, and when the cleaning plastic ball moves back and forth in the conveying pipeline to wash the inside of the conveying pipeline, the probability of irregular movement of the cleaning plastic ball can be increased due to the action of the steel balls, so that the cleaning plastic ball can more comprehensively clean the inside of the conveying pipeline; meanwhile, as the steel balls are arranged in the cleaning plastic balls, after cleaning is completed, the cleaning plastic balls can be moved to the lower end of the conveying pipeline quickly, and the cleaning plastic balls can be conveniently and quickly recycled without affecting the normal conveying function of the conveying pipeline.

Preferably, as an improvement, the supply air duct slope sets up, and the high-end of supply air duct is connected on pipeline, the bottom department of supply air duct opens there is the bin outlet, and bin outlet department can dismantle and be connected with the apron.

Because the air supply outlet is in an open state when the conveying pipeline is cleaned, especially when the conveying pipeline is required to be cleaned when different types of rice are processed, part of residual rice can be cleaned, and because the density of the rice is high, the rice can slide downwards into the air supply pipeline along the conveying pipeline in the cleaning process; simultaneously, the air supply pipeline is arranged in an inclined mode, so that the air in the air supply pipeline can be more conveniently led to enter the conveying pipeline and then spirally ascend, and the inner wall of the conveying pipeline is better cleaned.
