Description

Technical Field

[0001] The utility model relates to a material discharging device for garbage processing equipment, in particular to an automatic docking device for a leachate discharging port of a garbage compression box. Background Art

[0002] As living standards improve, demands for environmental sanitation are becoming increasingly stringent. The daily waste volume processed by waste transfer stations is increasing, and the scale of newly built waste transfer stations is also increasing. This has led to a growing workload for waste collection, transportation, and sanitation personnel within these stations. Waste treatment equipment is also becoming increasingly sophisticated, leading to increasingly complex and specialized equipment types, larger and larger equipment sizes, and a higher degree of automation requirements. Unmanned operation is becoming a future trend.

[0003] In the process of unmanned operation improvement, the original equipment in the garbage transfer station is also being transformed, updated or upgraded. In the existing technology, after the garbage compression box is full of garbage and arrives at the garbage transfer station, the garbage needs to be squeezed and the squeezed liquid is discharged into the sewage tank for temporary storage, and then the solid garbage and liquid garbage are classified and processed separately to achieve reasonable utilization or pollution-free discharge.

[0004] When the garbage compression box is full of garbage, it needs to be returned to the garbage transfer station. When the garbage is squeezed, the leachate discharge port needs to be connected to the sewage tank through a suction pipe. After the garbage compression box enters the station and arrives at a specific location near the sewage tank along a specific route in the station, it needs to be connected to the suction pipe and connected to the sewage tank. In the existing technology, connecting the suction pipe and switching the drain valve are performed manually. In order to improve the docking efficiency, a plug-in structure is generally used to achieve rapid docking, and then the valve is manually opened and closed. After the compression is completed, the valve is closed manually, the tube is manually pulled out, and other compression boxes are replaced. The repeated plug-in and switch processes and frequent operations take up a lot of staff time, which affects both work efficiency and equipment efficiency.

[0005] In order to save manpower and improve efficiency, it is necessary to modify the above-mentioned material connection port to improve the degree of automation, realize efficient and accurate connection between the compression box drain outlet and the discharge pipe, improve work efficiency and reduce long-term operating costs.

The automatic docking device includes a retractable corrugated hose at the connecting end of the suction pipe, and the front end of the corrugated hose is connected to a flange pipe for docking with the discharge port of the valve body. The flange pipe is provided with a straight pipe portion, and an axial displacement adjustment mechanism is connected to the pipe wall of the straight pipe portion of the flange pipe for adjusting the docking position of the flange pipe and the discharge port of the valve body.

[0008] The beneficial effect of the automatic docking device for the discharge port of the utility model is that the valve body is arranged at the discharge port of the compression box. In the non-compression state, the valve body is normally closed, and the actuator and docking device for switching the valve body are fixedly arranged in the garbage station, next to the sewage tank; after the compression box is in place, the valve body and the suction pipe are automatically docked through the automatic docking device, and the valve body is opened by the actuator after the automatic docking to realize extrusion and discharge, and the suction material of the automatic docking device is automatically docked with the discharge port of the valve body through the linear translation of the flange pipe. After docking, the actuator can open the valve body to realize automatic docking of the compressed liquid discharge port and automatic opening of the valve.

The cylinder body of the cylinder is fixed on the fixed frame, the telescopic rod of the cylinder is fixed to the movable frame, the movable frame and the fixed frame are connected by a guide rail slider mechanism, and the movable frame is connected to the flange pipe through a first connecting plate.

[0010] In order to ensure the precise axial linear docking movement of the flange docking interface, the fixed frame includes at least four supporting legs, two groups of parallel vertical plates connecting the supporting legs, and a horizontal cross bar perpendicular to the vertical plates.

[0011] In order to facilitate the installation of the actuator, an actuator connecting seat is fixed to the front end of the movable frame, and the actuator is fixed on the upper side of the actuator connecting seat.

[0012] In order to ensure the alignment of the actuator and the driving block, the actuator is a pneumatic actuator, the output end of the actuator extends from the bottom side of the actuator connecting seat, the actuator connecting seat is provided with a through hole, the output end of the actuator is connected with a concave block, the driving block of the valve body is a convex block, and after the discharge port of the valve body is docked with the flange pipe, the convex block and the concave block are docked together, and the actuator can switch the valve body.

[0013] In order to adapt to the height deviation of the compression tube discharge port, the support legs of the fixed frame can be telescopically raised and lowered to adjust the support height.

[0014] In order to prevent contact and impact when the butt joints are butted together, a rubber gasket is fitted on the flange surface of the flange pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] like Figure 1 — Figure 3 The figure shows the automatic docking device for the discharge port of the present invention, comprising a valve body 1 connected to the discharge port of the compression box. The valve stem of the valve body 1 is connected to a drive block 2, which is driven by an actuator 3 to open and close the valve body. In the present invention, the valve body 1 is connected to the drive block 2 and is separately connected to the actuator. When the compression box is full of garbage and needs to be squeezed and discharged, the entire box is transported to the vicinity of the sewage tank via a hoist or rail guide, and the valve body is driven to a position where it docks with the suction pipe. One end of the suction pipe is connected to the automatic docking device 4 via a flange interface 6, and the actuator 3 is mounted on the automatic docking device 4. The automatic docking device 4 of the present invention includes a retractable corrugated hose 411 connected to the interface of the suction pipe through a flange interface. The front end of the corrugated hose 411 is connected to a flange pipe 405 for docking with the discharge port of the valve body 1. The flange pipe 405 is provided with a straight pipe portion. An axial displacement adjustment mechanism is connected to the wall of the straight pipe portion of the flange pipe 405, which is used to adjust the docking position of the flange pipe 405 and the discharge port of the valve body 1 when the flange end is docked with the discharge port of the valve body 1; in order to protect the sealing performance of the docking part, a rubber gasket 7 is fitted on the flange surface of the flange pipe 405.

[0022] To facilitate automatic docking, the axial displacement adjustment mechanism of the present invention includes a cylinder 409, a fixed frame 408 and a movable frame 406. The cylinder body of the cylinder 409 is fixed on the fixed frame 409, the telescopic rod of the cylinder is fixed to the movable frame 406, the movable frame 406 is connected to the fixed frame 408 through a guide rail slider mechanism, and the movable frame 406 is connected to the flange pipe through the first connecting plate 401.

[0023] The fixed frame 408 of the present invention includes at least four supporting legs 402, two sets of parallel vertical plates 407 connecting the supporting legs 402, and a horizontal crossbar 410 perpendicular to the vertical plates 407. The horizontal crossbars 410 are fixedly connected to the ends of the vertical plates 407, and the upper and lower sides of each end are connected to the horizontal crossbar 410 to ensure the overall strength of the fixed frame. A cylinder 409 is horizontally arranged between the upper and lower horizontal crossbars 410. Guide rails 404 are respectively provided on the inner sides of the corresponding sets of vertical plates 407. Sliders 403 are slidably connected to the guide rails 404. The movable frame 406 is fixed between the sliders 403. A second connecting plate 412 is provided in the center of the front side of the movable frame 406. The second connecting plate 412 is fixedly connected to the front end of the piston rod of the cylinder 409. To accommodate the height deviation of the compression tank discharge port, the supporting legs 402 of the fixed frame can be telescopically raised and lowered to adjust the support height.

[0024] To facilitate the installation of the actuator 3, an actuator connecting seat 5 is also fixed to the front end of the mobile frame 406, and the actuator 3 is fixed on the upper side of the actuator connecting seat 5; to ensure the alignment of the actuator 3 and the drive block 2, the actuator 3 is a pneumatic actuator, and the output end of the actuator 3 extends from the bottom side of the actuator connecting seat 5. The actuator connecting seat 5 is provided with a through hole, and the output end of the actuator 3 is connected with a concave block. The drive block 2 of the valve body is a convex block. After the discharge port of the valve body 1 is docked with the flange pipe 405, the convex block and the concave block cooperate to dock, and the actuator 3 can switch the valve body when it is actuated.

[0025] The automatic docking device for the discharge port of the present invention is installed at the liquid inlet of the sewage tank, and a suction valve is connected to the liquid inlet pipe of the sewage tank. When the garbage compression box is full of garbage and transported to the position of the route of the vehicle next to the liquid inlet of the sewage tank, the valve body of the discharge port of the compression box is located at the position corresponding to the axial direction of the flange pipe of the automatic docking device. When the valve body reaches the predetermined position range, the cylinder 409 of the automatic docking device starts to move, the cylinder rod extends and moves, driving the mobile frame and the actuator 3 to move horizontally toward the valve body. The concave block 301 at the lower end of the actuator 3 gradually docks with the convex block, and the direct and complete docking is successful. The actuator 3 moves to open the valve body and connect the compression pipe discharge pipe with the liquid inlet pipe of the sewage tank; then the compression box starts to squeeze, and the suction pipe of the sewage tank starts to suck in liquid until the compression is completed. The actuator moves, the valve body is closed, the suction stops, the convex block and the concave block are separated, and then the cylinder 409 retracts, the automatic docking device reverses smoothly, the interface is separated, and the compression box is removed, completing a compression and liquid discharge process of the compression box.
