In some embodiments, friction is generated during the back-and-forth sliding of the gate plate, the wear compensation hard polymer adopts polyurethane plates, the wear compensation is performed by adopting elastic polyurethane plates above and below the gate plate, a certain pressure is given to the wear compensation hard polymer in advance, the wear compensation hard polymer can be compressed and deformed under the pressure, and when the wear compensation hard polymer is worn, the wear compensation is achieved by compressing and releasing a part of deformation.

The power supply component of the lower screw conveyer is positioned at the left end of the screw conveyer in the figure, and the materials can be conveyed out of the bin by using the screw shaft 101 in the working process of the motor.

The discharging bin is positioned at the middle upper part of the material cleaning and conveying device, the position of the discharging bin is fixed by mechanical fit and the whole frame 104, the left end is provided with a second feeding hole 302 connected with the pipeline 2, the lower part is provided with a second discharging hole 303 connected with a middle orifice sliding gate valve, the right part is provided with a vent 301 connected with a cyclone separator (a form of the dust removing structure 9, which can be replaced by a centrifugal separator) through the pipeline 2, and the spiral feeding structure 1 sucks scattered material particles into the discharging bin.

The surge bin is located at the lower part of the discharge bin and is fixed in position by mechanical cooperation with the integral frame 104, and the upper middle orifice slide gate valve opens the valve switch to deliver the material into the surge bin.

The dust removing device-cyclone separator is positioned at the right part of the discharging bin in the figure, the position of the dust removing device-cyclone separator is fixed by mechanical cooperation and the integral frame 104, and the dust removing device is connected with the blower through the pipeline 2 and achieves the purpose of dust removal by utilizing centrifugal force.

The invention has the beneficial effects that:

the invention has reasonable structural design, standard size and customized size, is mostly detachably connected, is convenient to maintain and clean and has longer service life.

The invention has compact and clear structure and simple and convenient operation, can be used for completing the task of collecting and transferring the scattered materials only by people who simply know the task, maximally reduces the influence of personnel replacement on the function of the device, and improves the efficiency of timely delivering the scattered materials out of the bin;

the middle orifice sliding gate valve has reasonable structural design, adopts the air cylinder 501 to provide power, realizes the optimization of power elements, does not consume additional energy, can effectively reduce the energy waste and the working strength of power elements, can effectively reduce the energy consumption, and reduces the equipment failure rate and the equipment investment cost;

4) compared with the traditional orifice valve frame 104, the middle orifice sliding gate valve has a simple structure, is convenient to maintain and use, can realize self-cleaning of the inside, and is energy-saving and environment-friendly.

5) The middle orifice sliding gate valve of the present invention has standard and custom dimensions and uses wear compensating hard polymer seals to selectively extend service life on the basis of maintenance functionality and extended life.

6) The pneumatic conveying device provided by the invention provides pneumatic conveying power through the pneumatic source 8, conveys and collects scattered materials, realizes the integration of cleaning and collecting the materials, runs stably, can greatly improve the conveying and collecting efficiency, saves the cost, can be used in multiple purposes, and is suitable for various occasions.

This material clearance conveyor cleans up the novel equipment of operation of transporting as storage product. During the cleaning of the material, the blower as a pneumatic source 8 transfers mechanical energy to the air, causing a pressure differential to be created in the air and enabling it to flow within the pipe. The motor drives the screw shaft 101 to rotate through the advance of the trolley, materials are collected and conveyed to the impeller 102 area in the middle of the screw shaft 101 along with the pushing of the screw blade 103, the materials are stirred to the pipeline 2 through the rotation of the impeller 102, the materials are conveyed and collected to the discharging bin under the pressure difference, and the discharging operation is started after the materials reach the discharging bin. At the moment of starting unloading, the upper middle orifice sliding gate valve is opened, the materials reach the buffer bin, when the materials are accumulated to a certain volume, the lower middle orifice sliding gate valve is opened, the materials reach the spiral discharging device, and finally the materials are conveyed out of the bin; when the material is unloaded, the dust in the material is sent to a dust removal module-cyclone separator through the pneumatic source 8, so that the purpose of dust removal is achieved. The whole integration of transporting is collected in the material clearance that has realized, the stability of greatly increased slag clearance collection. The material cleaning and conveying device is stable in operation, can be used in multiple purposes, and is suitable for various occasions, such as industries of food, cereals, medicines, chemical industry, mineral products and the like. Meanwhile, the labor cost for maintaining the granary is reduced, and the economic benefit of the granary is indirectly improved. The use of the device is favorable for the intelligent unmanned development of the material cleaning and collecting operation.

The invention relates to cleaning and collecting operations of stored food, grain, medicine, chemical industry, mineral products and the like, in particular to a seamless butt joint with a stereoscopic warehouse, which is mainly integrated and streamlined in the whole cleaning process and the conveying process of scattered materials and improves the cleaning efficiency. The motor or the hydraulic cylinder is used as a power device, so that pollution-free, zero-emission, energy-saving and environment-friendly effects are realized; meanwhile, the driving motor and the hydraulic cylinder can be controlled by the control system, and the intelligent cleaning and transferring device for cleaning scattered materials is realized.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
