Description

Technical Field

[0001] The utility model relates to the field of installation of material inlet and outlet valves, in particular to an automatic docking structure of a discharge valve and a material receiving port. Background Art

[0002] As daily waste volumes increase, the scale of newly built waste transfer stations is also increasing, increasing the 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 level 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. Utility Model Content

[0005] Aiming at the shortcomings of the manual docking structure between the leachate discharge port of the garbage compression box and the sewage tank suction pipeline in the prior art, the present invention provides an automatic docking structure between the discharge valve and the receiving port to solve the problems of waste of manpower and low efficiency caused by manual docking.

[0006] The purpose of the present utility model is achieved in this way. An automatic docking structure for a discharge valve and a material receiving port includes a ball valve and an actuator. The characteristic is that the ball valve is connected to the discharge port of a mobile material box, the actuator is connected to a part of a material receiving device close to the material receiving port, the actuator is used to drive the valve stem of the ball valve to switch the ball valve, the valve stem end of the ball valve is connected with a protrusion, the output end of the actuator is connected with a concave block that cooperates with the protrusion guide to dock, and when the ball valve and the material box move to the material receiving port of the material receiving device, the protrusion and the concave block cooperate to dock to form a mutually engaged structure.

[0007] The beneficial effects of the automatic docking structure of the discharge valve and the material receiving port of the present invention are as follows: the ball valve connected to the discharge port and the actuator for opening and closing the ball valve are respectively arranged on the mobile material box and the material receiving device, ensuring that the discharge port ball valve is normally closed in the non-discharging state. During the docking process of the ball valve and the material receiving device, the ball valve gradually engages with each other under the guiding cooperation of the protrusion and the concave block to finally achieve accurate docking, and then the ball valve is opened through the action of the actuator to connect the material receiving device. The automatic docking structure of the discharge valve and the material receiving port of the present invention enables the material box to achieve precise docking along the guiding cooperation direction of the protrusion and the concave block, and realizes the process of automatic docking and opening and closing the ball valve when the material box approaches the material receiving device, eliminating the process of manual docking operation, and also improving the docking accuracy to avoid material leakage at the docking part.

[0008] To facilitate the installation of the actuator, the actuator is connected to the material receiving device through a connecting seat, and the connecting seat is connected to the side of the material receiving port of the material receiving device. The actuator is a pneumatic actuator, and the output end of the pneumatic actuator passes through and extends to the other side of the connecting seat. The connecting seat is provided with a through hole at the position corresponding to the output end of the actuator, and the concave block is fixed to the protruding output end of the pneumatic actuator.

[0009] In order to facilitate the guiding cooperation between the protrusion and the concave block, the concave block fitting part is provided with a trapezoidal groove with a gradually narrowing opening. The fitting part of the protrusion is a trapezoidal protrusion that is guided and fitted with the trapezoidal groove. When the protrusion and the concave block approach each other, the trapezoidal groove guides and gradually guides and fits with the trapezoidal protrusion until the trapezoidal inclined surface is tightly fitted.

[0010] In order to ensure that the convex block and the concave block are firmly embedded, a straight guide section is provided at the narrowest end of the embedding portion of the convex block and the concave block.

[0011] Furthermore, the mating corresponding directions of the convex block and the concave block are arranged horizontally, and the notch of the trapezoidal groove of the concave block corresponds horizontally to the convex block. BRIEF DESCRIPTION OF THE DRAWINGS

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances. The following describes the embodiments of the present invention based on its overall structure.

[0019] like Figures 1-4 As shown, the automatic docking structure of the discharge valve and the material receiving port of the utility model includes a ball valve 1 and an actuator 2. The ball valve 1 is connected to the discharge port of the mobile material box, and the actuator 2 is connected to the part of the material receiving device close to the material receiving port. The actuator 2 is used to drive the valve stem of the ball valve 1 to switch the ball valve 1. The end of the valve stem of the ball valve 1 is connected with a protrusion 101, and the output end of the actuator 2 is connected with a concave block 201 which is guided and docked with the protrusion 101. When the ball valve 1 and the material box move to the material receiving port of the material receiving device, the protrusion 101 and the concave block 201 are docked to form a mutually engaged structure.

[0020] To facilitate the installation of the actuator 2, the actuator 2 is connected to the material receiving device through the connecting seat 202. The connecting seat 202 is connected to the side of the material receiving port of the material receiving device. The actuator 2 is a pneumatic actuator. The output end of the pneumatic actuator passes through and extends to the bottom side of the connecting seat 202. The connecting seat 202 is provided with a through hole at the position corresponding to the output end of the actuator. The concave block 201 is fixed to the protruding output end of the pneumatic actuator. In this way, the engaging groove part of the concave block 201 extends downward on the bottom side of the connecting seat to facilitate the guided engagement with the protrusion 101 that is moved closer.

[0021] To facilitate the guiding and mating of the protrusion 101 and the concave block 201, a gradually narrowing trapezoidal groove is provided at the mating portion of the concave block 201. The mating portion of the protrusion is a trapezoidal protrusion that is guided and engaged by the trapezoidal groove. As the protrusion 101 and concave block 201 approach, the trapezoidal groove and the trapezoidal protrusion gradually guide and engage until the trapezoidal inclined surfaces are tightly aligned. To ensure a secure fit between the protrusion 101 and concave block 201, a straight guide section L is provided at the narrowest end of the mating portion between the protrusion 101 and concave block 201.

[0022] Furthermore, the mating corresponding directions of the convex block 101 and the concave block 201 are arranged horizontally, and the notch of the trapezoidal groove of the concave block corresponds horizontally to the convex block.

[0023] The utility model relates to an automatic docking structure between a discharge valve and a receiving port, wherein a ball valve 1 connected to the discharge port and an actuator 2 for opening and closing the ball valve are respectively arranged on a mobile material box and a receiving device, to ensure that the ball valve of the discharge port is normally closed in a non-discharging state. During the docking process between the ball valve 1 and the receiving device, the protruding block 101 and the recessed block 201 gradually engage with each other under the guiding cooperation to finally achieve accurate docking, and then the action of the actuator 2 realizes the opening of the ball valve 101 to connect the receiving device.

[0024] The automatic docking structure of the discharge valve and the receiving port of the present utility model can be used to connect the filtrate discharge port of the garbage compression box at a garbage transfer station with the liquid inlet of a sewage tank. The ball valve is connected to the filtrate discharge port of the garbage compression box and moves with the garbage compression box as a whole. The ball valve is normally closed in the non-compression state. The actuator is connected to the side of the sewage tank inlet and fixed to the liquid inlet end of the sewage tank via a connecting seat. The liquid inlet is equipped with a suction pipeline and a suction valve. When the compression box is filled with garbage and transported to the garbage transfer station along a predetermined route, the protrusion and concave blocks gradually engage with each other as they approach the liquid inlet along a predetermined straight line until they are finally tightened. The actuator is activated, the discharge pipeline is connected, and the automatic docking process is completed. This eliminates the need for manual docking, saves manpower, and improves efficiency.

[0025] The automatic docking structure between the discharge valve and the receiving port of the utility model is also applicable to the docking parts of other material inlets and outlets. As long as the ball valve with a protrusion and the actuator with a recessed block are respectively arranged at the docking parts of the discharge and receiving components according to actual needs, and the appropriate docking route and docking orientation are set, the application can be changed.
