Technical Field

The invention relates to the technical field of equipment for innocent treatment and resource utilization of carcasses of animals died of diseases, in particular to a cleaning device for a sealed conveying pipeline of crushed granular manure slurry of the livestock died of diseases.

Background

The traditional harmless treatment mode of the waste livestock and poultry is incineration or deep burying, but a large amount of resources are wasted in the mode intangible, the improved treatment mode is disclosed as a liquid amino acid compound produced by CN103804032A utilizing dead pig protein and application thereof, and a CN104190694A zero-pollution harmless treatment and high-added-value resource utilization process of the livestock and poultry dead in illness, and the protein resources of the livestock and poultry are fully utilized in the process of harmless treatment of the waste livestock and poultry, so that the pollution to the environment is avoided, and the utilization rate of the waste livestock and poultry is improved.

The process route for improving the utilization rate of the waste livestock and poultry is as follows: crushing dead livestock and poultry carcasses to obtain a solid-liquid mixed material of blood, bone and meat particles, fat, liquid dung and the like, and hydrolyzing the solid-liquid mixed material to obtain oil and amino acid stock solution. Traditional solid-liquid mixture conveying equipment is screw conveyer or belt conveyor, and the defect lies in: the sealing performance of the equipment is poor, and the foul liquid such as the blood, the liquid dung and the like leaks in a long-term manner, so that the equipment is corroded, the environment is polluted, and diseases are spread.

Improved technical scheme as CN10640703A, contain and connect the hopper, connect the hopper bottom and inhale the chamber intercommunication, connect the hopper to be close to the position of inhaling the chamber and be provided with the feed valve that is used for closing and opening the feeder hopper, the tip of inhaling the chamber is provided with ejection of compact pipeline, the last bleeder valve that is provided with of ejection of compact pipeline, the tip of inhaling the chamber and keeping away from ejection of compact pipeline is provided with the drive cylinder body, the piston rod of drive cylinder body stretches into and inhales intracavity portion, the piston rod tip equipment has the piston to push away the head, the piston pushes away the head and slides along inhaling the. The using process is as follows: closing the discharge valve, opening the feed valve, driving the piston rod of the cylinder body to drive the piston push head to exit the suction cavity, sucking the material into the suction cavity, closing the feed valve, opening the discharge valve, driving the piston rod of the cylinder body to drive the piston push head to go deep into the suction cavity, and pushing the material out to the discharge pipeline. The feeding hopper supplies materials continuously, and the discharging pipe is full of materials.

The defects of the improved scheme are as follows: the material in the discharging pipe is pushed by the material in the suction cavity, and when the feeding hopper does not continuously supply the material, the material in the discharging pipe cannot be discharged. Based on suitable ambient temperature, the material in the discharging pipe can further decay and deteriorate, and the rotten material of one side corrodes the pipeline with higher speed, and on the other hand decay produced gas can increase intraductal pressure among the rotten process, and the sealing washer of pipeline junction or pipeline thin skin department burst easily, finally lead to the filth to spray and leak, the polluted environment also brings the infection risk for the field personnel.

Detailed Description

The following description of the embodiments of the present invention will be made with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

The discharge valve is closed, and the branch pipe valve is opened, and the broken granule excrement thick liquids of beasts and birds that die of illness in the air compressor machine's the air extrusion pipeline to in pushing slurry material to the pressure release jar, the material of pressure release jar is discharged to the jar of hydrolysising in through the discharging pipe. The relative position of the feeding hole and the discharging hole of the discharging pipe is not particularly limited, and the discharging pipe can be a lifting pipe, a horizontal pipe or a material dropping pipe.

In order to timely release the pressure in the pressure release tank, a positive pressure breather valve is arranged on the pressure release tank, and the positive pressure breather valve is used for releasing gas in the tank when the pressure in the pressure release tank is greater than the pressure outside the tank. In addition, the pressure release tank not only releases high-pressure gas in the tank generated during pipeline cleaning, but also can ferment and release gas under the condition of proper temperature due to the fact that slurry is attached to the inner wall of the cleaned pipeline, and the inner cavity of the pressure release tank is large and can store or release the gas generated by fermentation through the positive pressure breather valve.

Furthermore, in order to avoid the odor of the gas released from the pressure release tank from escaping, the positive pressure breather valve is connected with the deodorization system through an exhaust pipe.

The bottom discharge gate and the discharging pipe cooperation operation of negative pressure breather valve and pressure release jar: the negative pressure breather valve is arranged in introducing the air to the pressure release jar, and the atmospheric pressure outside jar in the balanced jar, the thick liquids in the jar are because the dead weight falls into the discharging pipe, and is further, and the discharge gate of discharging pipe is less than the feed inlet, and the material in the discharging pipe falls to the jar of hydrolysising because of the dead weight, reduces the use of drive feeding equipment, and the energy consumption is little.

The feed inlet of arranging the material pipe is less than the discharge gate, and the gas pressure that needs to consume is great in showing the material propelling movement to the pressure release jar, and the pressure storage tank helps promoting air pressure and keeps certain pressure value.

The piston driving member drives the piston to reciprocate along the position between two ends of the push-pull cylinder, the reciprocating motion is generally linear motion, and therefore the driving member is a linear driver, namely an actuating element which reciprocates linearly, including but not limited to a linear air cylinder and a linear oil cylinder. Specifically, the driving piece is a linear hydraulic cylinder, and a piston rod of the hydraulic cylinder is hinged with a piston of the push-pull cylinder. The height of the material to be lifted depends on the pressure of the hydraulic cylinder, and when the pressure of the hydraulic cylinder is 6Mpa, the solid-liquid mixed material can be sent into a hydrolysis tank with the height of 25 m.

The discharge valve and the branch valve are required to meet the use requirements of stopping gas and liquid slurry, while the feed valve is used for stopping liquid slurry, and the specific valve types are based on the use requirements, including but not limited to common knife gate valves.
