Description

Technical Field

[0001] The utility model relates to the technical field of feed bins, in particular to a low-temperature pyrolysis anti-blocking feed bin. Background Art

[0002] Medical waste is mainly composed of gauze, plastic hoses, a small amount of metal products and pollutants generated during hospital diagnosis and treatment. It is an infectious and toxic hazardous waste. At present, my country has established a full-process supervision system for the use, transportation and treatment of medical waste. After the medical waste is transported to the decomposition site, it enters the pyrolysis system through a feed bin or a feed hopper. For example, in the medical waste pyrolysis system and pyrolysis method based on low-temperature pyrolysis with the publication number CN116871298A, the feeding method adopts a feed bin, but the feed quantity of the feed bin is limited, and the material entering from the feed hopper is pushed by a propulsion mechanism, and the feed is limited; while the feed bin can be used to quantitatively feed bulk materials, and the feed bin can also adopt a heightened or semi-enclosed design to prevent the material from splashing during the crushing process to ensure safe operation.

[0003] In the actual use of the existing low-temperature pyrolysis feed bin, a screw conveyor is set at the bottom of the feed bin for conveying. The screw conveyor can only convey medical waste at the bottom. Therefore, in actual use, it is easy for medical waste to enter the low-temperature pyrolysis equipment and often block the feed port. The screw conveyor runs idle and cannot convey the material located at the top of the feed bin, affecting the feeding efficiency. If the personnel do not find it in time, the feed bin may overflow. In similar fields, the feed bin with a vibrating screening device consumes manpower and has low efficiency, but it is not convenient to use in the low-temperature pyrolysis system. It uses vibration to prevent blockage, which has high requirements for the device of the feed bin and high cost.

[0004] Therefore, in response to the above problems, a low-temperature pyrolysis anti-blocking feed bin is proposed, which facilitates the smooth entry of medical waste into the screw conveyor and is transported to the designated location by the screw conveyor, thereby avoiding the problem of medical waste being suspended in the feed bin, which is not conducive to the feeding of medical waste. Utility Model Content

[0005] In view of the deficiencies in the above-mentioned background technology, the utility model proposes a low-temperature pyrolysis anti-blocking feed bin, which solves the problem in the prior art that the feed bin is easily blocked by medical waste, affecting the feeding of medical waste.

A toggle plate corresponding to the screw conveying mechanism is provided on the toggle mechanism. The toggle plate is located in the bin body, and the control system controls the connection between the toggle mechanism and the screw conveying mechanism.

[0007] Furthermore, the toggle mechanism includes a toggle shaft, a toggle plate is fixedly connected to the toggle shaft, the toggle shaft is passed through the bin body and connected to a toggle motor arranged outside the bin body, and both ends of the toggle shaft are provided with limit rings and sealing components.

[0008] Furthermore, the sealing assembly includes a reset spring and a movable cone cover group, the reset spring is located inside the movable cone cover group and is used to reset the movable cone cover group, the movable cone cover group is sleeved on the dial shaft, and the movable cone cover group is located between the limit ring and the warehouse body.

[0009] Furthermore, the movable cone cover group includes cone cover one and cone cover two, cone cover one is movably sleeved on cone cover two, and both cone cover one and cone cover two are provided with supporting pads matched with reset springs.

[0010] Furthermore, the warehouse body is provided with a strip hole that cooperates with the shifting shaft.

[0011] Furthermore, the end of the shifting shaft is also connected to a manual adjustment component.

[0012] Furthermore, the manual adjustment component includes a movable connecting piece sleeved on the toggle shaft, a vertical rod is hinged on the movable connecting piece, and a control rod is connected to the lower part of the vertical rod.

[0013] Furthermore, the control rod comprises a cross bar, the middle part of which is hinged on a support column, and the support column is fixedly connected to a frame at the lower part of the warehouse body.

[0014] Furthermore, the movable connecting piece is connected to the toggle shaft via a bearing, and a connecting ear hinged to the vertical rod is provided on the outside of the movable connecting piece.

[0015] Furthermore, the connecting ear is also connected to a cross frame, and the toggle motor is fixedly connected to the cross frame.
