Description

Technical Field

[0001] This utility model belongs to the field of centralized material supply technology, and particularly relates to a pneumatic pull plate valve. Background Technology

[0002] Pneumatic conveying is an important method of material conveying. Also known as pneumatic air conveying, it utilizes the energy of airflow to transport granular materials along the airflow direction in a closed pipeline. It is a specific application of fluidization technology. Pneumatic pull-plate valves are often used in the process of pneumatic conveying.

[0003] Existing pneumatic pull-plate valves are often installed on the delivery pipeline using multiple bolts, which makes disassembly and installation complex when workers need to disassemble and maintain them, thus increasing maintenance time and reducing maintenance efficiency.

[0004] Therefore, we propose a pneumatic pull-plate valve to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that pneumatic pull-plate valves are inconvenient to disassemble from the conveying pipeline in the prior art, and therefore proposes a pneumatic pull-plate valve.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A pneumatic pull-plate valve includes a housing. A fixing plate is provided on the right side of the housing, and a cylinder is fixedly installed on the right side of the fixing plate. A pull-plate body is slidably connected inside the housing. The telescopic end of the cylinder passes through the fixing plate and is fixedly installed with a connecting plate. The left side of the connecting plate contacts the right side of the pull-plate body. A connecting pipe is fixedly connected to the upper and lower surfaces of the housing. A fixing ring is fixedly installed on the outer surface of each connecting pipe. A worm gear ring is provided on the side of the two fixing rings that are far apart from each other. The side of the two worm gear rings that are far apart from each other has equally spaced sliding grooves. A sliding block is slidably connected inside each sliding groove. A concave frame is fixedly installed on the upper and lower surfaces of the housing. A worm is rotatably connected inside each concave frame. The outer surface of each worm meshes with the outer surface of the worm gear ring. A rotating motor is provided on the front of each concave frame. The output end of each rotating motor is fixedly connected to the end of the worm closest to the rotating motor.

[0008] Preferably, the outer surface of the housing is threaded with two fixing bolts, and the right end of each fixing bolt extends through to the right side of the fixing plate.

[0009] Preferably, the connecting plate has two connecting bolts internally threaded together, and the left end of each connecting bolt penetrates into the interior of the plate body.

[0010] Preferably, a sealing groove is formed on the outer surface of each of the connecting pipes, and a sealing ring is snapped into the interior of each sealing groove.

[0011] Preferably, a connecting bearing is fixedly installed on the side of each of the two fixed rings that are far apart from each other, and the side of each of the two connecting bearings that are far apart from each other is fixedly connected to the side of each of the two worm gear rings that are close to each other.

[0012] Preferably, a limiting ring is fixedly installed on the outer surface of both connecting pipes, and the outer surface of each sliding block is slidably connected to the inner wall of the limiting ring.

[0013] Preferably, a protective box is fixedly installed on the front of each of the concave frames, and the sides of the two rotating motors that are close to each other are fixedly connected to the inner wall of the protective box.

[0014] Preferably, each of the protective boxes has a locking block and a locking frame fixedly installed on its left side, and each locking block is engaged inside the locking frame.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-5 The pneumatic pull plate valve includes a housing 1, a fixing plate 2 is provided on the right side of the housing 1, and a cylinder 3 is fixedly installed on the right side of the fixing plate 2. Two fixing bolts 14 are threadedly connected to the outer surface of the housing 1, and the right end of each fixing bolt 14 passes through to the right side of the fixing plate 2. The fixing bolts 14 are used to fix the housing 1 and the fixing plate 2, so that the worker can easily remove the fixing plate 2 from the housing 1, and thus facilitate the worker to maintain the internal components of the housing 1.

[0024] The pull plate body 4 is slidably connected inside the housing 1. The telescopic end of the cylinder 3 passes through the fixed plate 2 and is fixedly installed with a connecting plate 5. The left side of the connecting plate 5 contacts the right side of the pull plate body 4. Both the pull plate body 4 and the housing 1 are provided with through holes to facilitate the flow of materials. The connecting plate 5 is internally threaded with two connecting bolts 15. The left end of each connecting bolt 15 passes through the interior of the pull plate body 4. The installation of the connecting bolts 15 makes it easy for workers to remove the connecting plate 5 from the pull plate body 4, thereby facilitating the replacement of the worn pull plate body 4.

[0025] The upper and lower surfaces of the housing 1 are fixedly connected to the connecting pipes 6. Each connecting pipe 6 has a sealing groove 16 on its outer surface. Each sealing groove 16 has a sealing ring 17 inside it. The sealing ring 17 seals the gap between the connecting pipe 6 and the material conveying pipeline, thereby preventing material from leaking from the gap.

[0026] Each connecting pipe 6 has a fixed ring 7 fixedly installed on its outer surface. A worm gear ring 8 is provided on the side of the two fixed rings 7 that are far apart from each other. A connecting bearing 18 is fixedly installed on the side of the two fixed rings 7 that are far apart from each other. The side of the two connecting bearings 18 that are far apart from each other is fixedly connected to the side of the two worm gear rings 8 that are close to each other. The side of the outer ring of the two connecting bearings 18 that is close to each other is fixedly connected to the fixed ring 7. The side of the inner ring of the two connecting bearings 18 that is far apart from each other is fixedly connected to the worm gear ring 8. The installation of the connecting bearings 18 plays a role in stabilizing the worm gear ring 8, thereby preventing the worm gear ring 8 from shaking when rotating.

[0027] Two worm gear rings 8 each have equally spaced grooves 9 on their opposite sides. Each groove 9 has a sliding block 10 slidably connected inside it. Limiting rings 19 are fixedly installed on the outer surfaces of the two connecting pipes 6. The outer surface of each sliding block 10 is slidably connected to the inner wall of the limiting ring 19. The installation of the limiting ring 19 restricts the movement trajectory of the sliding block 10, thereby preventing the sliding block 10 from deviating from its movement trajectory and ensuring the stability of the movement of the sliding block 10.

[0028] Concave frames 11 are fixedly installed on the upper and bottom surfaces of the housing 1. A worm gear 12 is rotatably connected inside each concave frame 11. The outer surface of each worm gear 12 meshes with the outer surface of the worm wheel ring 8. A rotating motor 13 is provided on the front of each concave frame 11. The output end of each rotating motor 13 is fixedly connected to the end of the worm gear 12 near the rotating motor 13. A protective box 20 is fixedly installed on the front of each concave frame 11. The sides of the two rotating motors 13 that are close to each other are fixedly connected to the inner wall of the protective box 20. The installation of the protective box 20 serves to protect the rotating motors 13, thereby preventing external objects from colliding with the rotating motors 13.

[0029] Each protective box 20 has a locking block 21 and a locking frame 22 fixedly installed on its left side. Each locking block 21 is snapped into the inside of the locking frame 22. The installation of the locking block 21 and the locking frame 22 makes it convenient for workers to open the protective box 20, thereby facilitating the maintenance of the rotating motor 13.

[0030] The working principle of this utility model is as follows: In use, the worker first inserts the two connecting pipes 6 into the material conveying pipe, making the material conveying pipe contact the limiting ring 19. Then, the worker uses an external remote control to turn on the rotating motor 13. The power provided by the rotating motor 13 drives the worm gear 12 to rotate, which in turn drives the worm wheel ring 8 to rotate. This causes the worm wheel ring 8, in conjunction with the sliding groove 9, to move the sliding block 10 towards one side, thus clamping and fixing the material conveying pipe. This achieves the purpose of quickly installing the pneumatic pull valve on the material conveying pipe. When it is necessary to convey material... During delivery, the worker opens cylinder 3 via an external remote control device. The power provided by cylinder 3 drives the connecting plate 5 and the pull plate body 4 to move, thereby connecting the through hole on the pull plate body 4 with the through hole on the housing 1. This allows the material to flow sequentially through the connecting pipe 6, the housing 1, and the pull plate body 4, thus achieving the purpose of controlling the material conveying. When conveying multiple materials, the device is installed on different material conveying pipelines. According to the material requirements, different pneumatic pull plate valves are opened, thereby avoiding the problem of raw material contamination in multiple pipelines and reducing a series of problems such as frequent pipeline cleaning due to raw material contamination, and even product defects caused by raw material contamination.
