Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a storage and unloading device for kitchen waste extrusion residue, and in particular a storage and unloading device that facilitates the discharge of residue. Background Technology

[0002] The purpose of waste sorting is to reduce the amount of waste to be processed and the use of processing equipment, reduce processing costs, and increase the resource and economic value of waste. Among them, kitchen waste contains extremely high moisture and organic matter, which is easy to decompose and produce foul odors. It needs to be properly treated and processed to be transformed into new resources, such as fertilizer and feed, or to produce biogas for fuel or power generation. The oil portion can be used to prepare biofuel.

[0003] The treatment of kitchen waste generally involves first removing impurities to separate solid waste from oil and water, then separating the water and oil to obtain the grease portion for resource reuse.

[0004] Given that food waste sorting is currently in its initial stage and the impurity content in food waste is relatively high, it is necessary to temporarily store the residue separated at the back end of the waste treatment process to ensure continuous production and facilitate its transportation and dispatch. At the same time, due to the low density of the residue, centralized storage can easily lead to compaction and bridging, resulting in obstructed residue discharge.

[0005] In summary, to address the shortcomings of existing kitchen waste treatment equipment, this utility model designs a storage and unloading device for kitchen waste extrusion residue that has a reasonable structure and facilitates residue discharge. Summary of the Invention

[0006] To address the problems existing in the prior art, this utility model provides a storage and unloading device for kitchen waste compression residue that has a reasonable structure and facilitates slag removal.

[0007] The objective of this utility model can be achieved through the following technical solution: a storage and unloading device for kitchen waste extrusion residue, comprising:

[0008] The hopper has two guide plates symmetrically arranged on both sides inside. The two guide plates are bent and close to each other at the bottom. Each guide plate is composed of two inclined plates, namely an upper inclined plate and a lower inclined plate. The upper inclined plate is set at an angle α with the horizontal plane, and the lower inclined plate is set at an angle β with the horizontal plane.

[0009] A bidirectional screw is positioned across the middle of the hopper, and the bidirectional screw is located between two guide plates;

[0010] The conveying trough is fixed at the bottom of the two guide plates and is connected to the bottom of the two guide plates respectively. At least one conveying screw is provided in the conveying trough.

[0011] The slag discharge trough is inclinedly set at the bottom of the hopper, and a slag discharge screw is installed inside the slag discharge trough. The slag discharge trough is used to receive the slag material output from the conveying trough and transport it to a designated point.

[0012] As a further improvement in this case, α = 60° and β = 45°.

[0013] As a further improvement to this case, the aforementioned bidirectional screw is located on the plane where the upper inclined plate and the lower inclined plate meet.

[0014] As a further improvement in this case, the cross-section of the conveying trough is arranged in a "W" shape, and two conveying screws are arranged side by side in the conveying trough.

[0015] Compared with the prior art, the present invention has a reasonable structural design. The bending guide plates (upper inclined plate and lower inclined plate) increase the slag capacity space formed by the two guide plates, which is conducive to accommodating more slag. At the same time, the bidirectional screw between the two guide plates can disperse the slag to both sides, reducing the phenomenon of slag compaction and bridging. In addition, the conveying trough and two conveying screws are set at the bottom of the guide plates to speed up the slag discharge, avoid excessive slag stacking, and ensure smooth slag discharge.

[0019] In the diagram, 10 is the hopper; 11 is the upper inclined plate; 12 is the lower inclined plate; 13 is the guide plate; 14 is the bidirectional screw; 15 is the conveying trough; 16 is the conveying screw; 20 is the slag discharge trough; and 21 is the slag discharge screw. Detailed Implementation

[0020] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0021] like Figures 1 to 3 As shown, the storage and unloading device for kitchen waste compression residue includes:

[0022] The hopper 10 has two guide plates 13 symmetrically arranged on both sides inside. The two guide plates 13 are bent and their bottoms are close to each other. Each guide plate 13 is composed of two inclined plates, namely an upper inclined plate 11 and a lower inclined plate 12. The upper inclined plate 11 is set at an angle α with the horizontal plane, and the lower inclined plate 12 is set at an angle β with the horizontal plane.

[0023] A bidirectional screw 14 is positioned across the middle of the hopper 10, and the bidirectional screw 14 is located between the two guide plates 13;

[0024] The conveying trough 15 is fixed at the bottom of the two guide plates 13, and the conveying trough 15 is connected to the bottom of the two guide plates 13 respectively. At least one conveying screw 16 is provided in the conveying trough 15.

[0025] The slag discharge trough 20 is inclinedly set at the bottom of the hopper 10. The slag discharge screw 21 is installed inside the slag discharge trough 20. The slag discharge trough 20 is used to receive the slag material output from the conveying trough 15 and transport it to a designated point.

[0026] Given that food waste sorting is currently in its initial stage and the impurity content in food waste is relatively high, it is necessary to temporarily store the residue separated at the back end of the waste treatment process to ensure continuous production and facilitate its transportation and dispatch. At the same time, due to the low density of the residue, centralized storage can easily lead to compaction and bridging, resulting in obstructed residue discharge.

[0027] Therefore, this utility model provides a storage and unloading device for kitchen waste extrusion residue. By bending the guide plates 13 (upper inclined plate 11 and lower inclined plate 12), the residue capacity space formed by the two guide plates 13 is increased, which is conducive to accommodating more residue. At the same time, a bidirectional screw 14 is set between the two guide plates 13, which can disperse the residue to both sides and reduce the phenomenon of residue compaction and bridging.

[0028] Specifically, after the slag enters the hopper 10, it slides down along the two guide plates 13 to the bottom of the guide plates 13 and the conveying trough 15. As the amount of slag increases, it will pile up and compact at the bottom of the guide plates 13. During this process, the slag is broken up by the bidirectional screw 14. Then, the slag is conveyed to the slag discharge trough 20 via the conveying trough 15, and finally conveyed to the designated location by the slag discharge trough 20. Since the slag is usually piled up and compacted in a low-lying area, an inclined slag discharge trough 20 is required to convey the slag from bottom to top to the final designated location, facilitating subsequent loading and transportation.

[0029] Preferably, α = 60° and β = 45°.

[0030] In this embodiment, the two guide plates 13 are respectively welded together from two steel plates with different inclination angles (upper inclined plate 11 and lower inclined plate 12). The upper inclined plate 11 is at a 60° angle to the horizontal plane, and the lower inclined plate 12 is at a 45° angle to the horizontal plane.

[0031] This structural design ensures, on the one hand, that there is as large a slag capacity space as possible under the premise that the outer dimensions of the hopper 10 are the same, that is, increasing the slag capacity space formed between the two guide plates 13, which is conducive to accommodating more slag. On the other hand, it can increase the angle of the bottom slag sliding down, which can improve the phenomenon of bottom slag compaction and bridging to a certain extent.

[0032] Preferably, the bidirectional screw 14 is located in the plane where the upper inclined plate 11 and the lower inclined plate 12 meet.

[0033] Preferably, a bidirectional screw 14 is installed across the junction of the upper inclined plate 11 and the lower inclined plate 12 of the guide plate 13 (at the weld surface). In actual operation, it can simultaneously push the compacted slag to both sides, thereby breaking up the slag and preventing the slag from accumulating and causing stress concentration, which would lead to bridging. This facilitates the smooth discharge of the slag.

[0034] Furthermore, the cross-section of the conveying trough 15 is arranged in a "W" shape, and two conveying screws 16 are arranged side by side inside the conveying trough 15.

[0035] It is worth mentioning that in this embodiment, the conveying trough 15 adopts a double-slot configuration, and two conveying screws 16 are arranged side by side in the conveying trough 15. The speed of slag discharge is increased by the simultaneous operation of the two screws, thereby reducing the phenomenon of slag stacking, compaction and bridging.

[0036] The cross-section of the conveying trough 15 is arranged in a "W" shape, which can separate the two conveying screws 16, avoid interference between the two conveying screws 16 during operation, and also avoid the slag material intertwining, ensuring smooth slag discharge.

[0037] In addition, the conveying trough 15 adopts a dual-slot setting, which can increase the stacking width of the slag at the bottom of the guide plate 13 to a certain extent, thereby reducing the size difference between the top and bottom of the slag stack (i.e. reducing the height of the slag stack), further improving the slag compaction and bridging phenomenon, and improving the smoothness of slag discharge.

[0038] The storage and unloading device for kitchen waste extrusion uses bent guide plates 13 (upper inclined plate 11, lower inclined plate 12) to increase the extrusion capacity space formed by the two guide plates 13, which is conducive to accommodating more extrusion. At the same time, a bidirectional screw 14 is set between the two guide plates 13 to disperse the extrusion to both sides, reducing the phenomenon of extrusion compaction and bridging. In addition, a conveying trough 15 and two conveying screws 16 are set at the bottom of the guide plates 13 to speed up the extrusion of extrusion, prevent the extrusion of ...

[0039] The embodiments described herein are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or additions to the specific embodiments described, or substitutions made by those skilled in the art, should be covered within the scope of protection of the present invention.
