Description

Technical Field

[0001] The utility model relates to the technical field of anti-blocking silos, in particular to a silo which is convenient for cleaning sticky materials. Background Art

[0002] Wet and sticky materials tend to accumulate and form suspended materials on the inner wall of the silo, which reduces the effective volume of the silo and easily leads to blockage of material discharge. Therefore, silos suitable for wet and sticky materials are usually equipped with air cannons for material cleaning.

[0003] In the related art, a Chinese patent with authorization announcement number CN205045268U provides a self-controlled avalanche high-column powder silo high-efficiency cleaning and unloading control device, which includes a silo with an air cannon installed on the outer wall of the silo. When the air cannon is started, the air cannon instantly converts the air pressure energy into air jet kinetic energy, thereby generating a strong impact force on the compacted wet and sticky materials in the silo, achieving the effect of clearing the accumulated materials.

[0004] In the process of implementing this application, the inventors found that there are at least the following problems in this technology: since the effective cleaning area of ​​the air cannon is limited, when the height of the silo is high, the air cannon can only clear the area at a certain height in the silo, while other areas in the silo require manual entry into the silo for cleaning, which not only increases the labor cost of silo cleaning, but also poses a safety hazard to manual entry into the silo. Utility Model Content

[0005] In order to facilitate the cleaning of the interior of a silo and reduce the need for manual entry into the silo to clean the materials, the present application provides a silo that is convenient for cleaning sticky materials.

[0006] The present application provides a silo that is convenient for cleaning the sticky materials, which adopts the following technical solution:

[0007] A silo that is convenient for cleaning sticky materials comprises a hopper, a plurality of air supply pipes are connected to the hopper, a sealing cover is provided on one end of the air supply pipe away from the hopper, the sealing cover is used to close the air supply pipe, a support frame is provided outside the hopper, a mounting seat is slidably provided on the support frame, a lifting assembly is provided between the support frame and the mounting seat, the lifting assembly is used to drive the mounting seat to move in a height direction, an electric telescopic rod is fixedly provided on the mounting seat, an air cannon is fixedly provided on the output shaft of the electric telescopic rod, an output pipe is connected to the output end of the air cannon, and the output pipe is used to connect the air cannon with the air supply pipe.

[0008] By adopting the above technical solution, during the upward movement of the mounting seat, when the air cannon moves to a position relative to a certain air supply pipe, the electric telescopic rod drives the air cannon to move toward the hopper. During the movement of the air cannon toward the hopper, the sealing cover plate opposite to the air cannon exposes the air supply pipe port, thereby facilitating the connection between the output pipe and the air supply pipe. When the output pipe connects the air cannon with the air supply pipe, the air cannon starts to generate impact force on the inside of the hopper to form a cleaning effect. Then the electric telescopic rod drives the air cannon to move toward the support frame to reset. During the movement of the air cannon toward the support frame, when the output pipe is separated from the air supply pipe, the sealing cover plate again seals the air supply pipe away from the hopper, making it difficult for materials in the hopper to pass. To prevent leakage through the air supply pipe, when the hopper is loading, unloading and storing materials normally, the mounting seat is placed still near the bottom support frame. At this time, the output pipe is separated from the air supply pipe, and the sealing cover plate closes the end of the air supply pipe away from the hopper, so that the material in the hopper is not easy to leak through the air supply pipe. When clearing the hopper, the mounting seat moves from bottom to top under the drive of the lifting assembly, and then the mounting seat drives the electric telescopic rod and the air cannon to move, so that the air supply pipe on the hopper is connected to the air cannon from bottom to top in turn to complete the cleaning operation. When the hopper is at a high height, the air cannon clears the different height areas of the hopper from bottom to top in turn, reducing the situation of manual entry into the silo to clean the material, so as to facilitate the cleaning of the inside of the silo.

[0009] Preferably, the lifting assembly includes a lifting slide rod and a lifting screw rod, the lifting slide rod is fixedly arranged on the support frame, the lifting slide rod passes through the mounting seat, the lifting screw rod is rotatably arranged on the support frame, and the lifting screw rod is threadedly connected to the mounting seat.

[0010] By adopting the above technical solution, when the lifting screw rotates, the lifting slide rod makes it difficult for the mounting seat to rotate synchronously with the lifting screw, thereby causing the mounting seat to move along the height direction of the support frame, thereby achieving the effect of moving the air cannon along the height direction.

[0011] Preferably, the lifting assembly further comprises a lifting motor, the lifting motor is fixedly arranged on the support frame, and the output shaft of the lifting motor is fixedly connected to the lifting screw rod.

[0012] By adopting the above technical solution, the lifting motor drives the lifting screw to rotate, thereby reducing the situation where the lifting screw is driven by manpower to rotate.

[0013] Preferably, a connecting seat is fixedly provided on the air supply pipe, a connecting sleeve is rotatably provided on the connecting seat, and a connecting rod is fixedly provided between a side wall of the connecting sleeve and a side wall of the sealing cover plate.

[0014] By adopting the above technical solution, the sealing cover plate is rotatably connected to the air supply pipe. When the end of the air supply pipe is exposed, the sealing cover plate is removed from the end of the air supply pipe by rotating the connecting sleeve.

[0015] Preferably, a driving sleeve is inserted into the connecting sleeve, the inner wall of the connecting sleeve is connected to the outer wall of the driving sleeve, a reset spring is fixedly arranged between one end of the driving sleeve and the connecting seat, the other end of the driving sleeve protrudes out of the connecting sleeve, the driving sleeve is used to abut against the output pipe, a limiting rod is inserted into the driving sleeve, the inner wall of the driving sleeve is slidably connected to the outer wall of the limiting rod, one end of the limiting rod is located in the driving sleeve, the other end of the limiting rod is fixedly connected to the connecting seat, and the reset spring is sleeved on the limiting rod.

[0016] By adopting the above technical scheme, the driving sleeve is not easy to rotate relative to the connecting seat under the limiting action of the limit rod. The limit rod and the connecting sleeve are not easy to move in the horizontal direction under the limiting action of the connecting seat. Therefore, when the driving sleeve moves in the horizontal direction, the driving sleeve and the limit rod only move relative to each other in the horizontal direction, and when the driving sleeve and the connecting sleeve move relative to each other in the horizontal direction, the driving sleeve forces the connecting sleeve to rotate. In the process of the air cannon driving the output pipe to move toward the hopper, after the output pipe abuts against the driving sleeve, the output pipe will continue to approach the hopper. At this time, the output pipe pushes the driving sleeve to move toward the hopper, and the driving sleeve forces the connecting sleeve to rotate forward, so that the connecting sleeve drives the sealing cover plate to rotate to expose the air supply pipe port. In the process of the air cannon driving the output pipe to move toward the support seat, the reset spring pushes the driving sleeve to move toward the support seat, and the driving sleeve forces the connecting sleeve to reverse, so that the connecting sleeve drives the sealing cover plate to rotate to close the air supply pipe port, thereby reducing the situation of manually driving the connecting sleeve to rotate.

[0017] Preferably, a driving ball is rotatably arranged on the outer wall of the driving sleeve, a driving groove is provided on the inner wall of the connecting sleeve, the driving ball is rollingly arranged in the driving groove, a limiting groove is provided on the outer wall of the limiting rod, a limiting block is slidably arranged in the limiting groove, and the limiting block is fixedly connected to the inner wall of the driving sleeve.

[0018] By adopting the above technical solution, when the driving sleeve moves in the horizontal direction, the limit block on the driving sleeve moves along the limit groove, so that the driving sleeve and the limit rod only move relative to each other in the horizontal direction, and the driving sleeve and the connecting seat are not easy to rotate relative to each other. When the driving sleeve moves in the horizontal direction, the driving ball on the driving sleeve moves along the driving groove. When the driving ball and the driving groove move relative to each other in the horizontal direction, the driving ball pushes the connecting sleeve to rotate.

[0019] Preferably, a guide tube is provided on one end of the output tube away from the air cannon, the air supply tube is inserted with the guide tube, and the outer wall of the guide tube is used to abut against the inner wall of the air supply tube.

[0020] By adopting the above technical solution, when the air supply pipe port is exposed, the guide pipe is inserted into the air supply pipe, and when the outer wall of the guide pipe abuts against the inner wall of the air supply pipe, the air cannon stops moving and starts.

[0021] Preferably, the outer diameter of the end of the guide tube close to the output tube is larger than the outer diameter of the end of the guide tube away from the output tube.

[0022] By adopting the above technical solution, the guide tube is arranged in a conical shape, which facilitates the insertion of the guide tube into the air supply pipe.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0034] The following is combined with Figure 1-6 This application is described in further detail.

[0035] The present application embodiment discloses a silo that is convenient for cleaning the sticky materials. Figure 1 , including a hopper 1, on which a plurality of air supply pipes 11 are connected, and the air supply pipes 11 are evenly distributed along the height direction. A sealing cover plate 12 is installed on the end of the air supply pipe 11 away from the hopper 1, and the sealing cover plate 12 is used to close the air supply pipe 11. A support frame 2 is arranged outside the hopper 1, and a mounting seat 21 is slidably arranged on the support frame 2. A lifting assembly 3 is installed between the support frame 2 and the mounting seat 21, and the lifting assembly 3 is used to drive the mounting seat 21 to move along the height direction. An electric telescopic rod 4 is installed on the mounting seat 21, and an air cannon 5 is installed on the output shaft of the electric telescopic rod 4, and the output end of the air cannon 5 faces the hopper 1. An output pipe 51 is connected to the output end of the air cannon 5, and the output pipe 51 is used to connect the air cannon 5 with the air supply pipe 11. During the upward movement of the mounting seat 21, when the air cannon 5 moves to a relative position with a certain air supply pipe 11, the electric telescopic rod 4 drives the air cannon 5 to move toward the hopper 1. During the movement of the air cannon 5 toward the hopper 1, the sealing cover plate 12 opposite to the air cannon 5 exposes the port of the air supply pipe 11, thereby facilitating the connection between the output pipe 51 and the air supply pipe 11. When the output pipe 51 connects the air cannon 5 with the air supply pipe 11, the air cannon 5 starts to generate impact force on the inside of the hopper 1 to form a cleaning effect, and then the electric telescopic rod 4 drives the air cannon 5 to move and reset toward the support frame 2. During the movement of the air cannon 5 toward the support frame 2, when the output pipe 51 is separated from the air supply pipe 11, the sealing cover plate 12 again seals the end of the air supply pipe 11 away from the hopper 1, so that the material in the hopper 1 is not easy to leak out through the air supply pipe 11. When the hopper 1 is normally loading, unloading and storing materials, the mounting seat 21 is stationary at a position close to the bottom support frame 2. At this time, the output pipe 51 is separated from the air supply pipe 11, and the sealing cover plate 12 seals the end of the air supply pipe 11 away from the hopper 1, so that the material in the hopper 1 is not easy to leak out through the air supply pipe 11. When the hopper 1 is cleared, the mounting seat 21 moves upward from bottom to top under the drive of the lifting assembly 3, and then the mounting seat 21 drives the electric telescopic rod 4 and the air cannon 5 to move, so that the air supply pipe 11 on the hopper 1 is connected with the air cannon 5 from bottom to top to complete the clearing operation. When the height of the hopper 1 is high, the air cannon 5 clears the different height areas of the hopper 1 from bottom to top, reducing the situation of manual entry into the hopper to clear the material, and achieving the effect of facilitating the clearing of the inside of the hopper.

[0036] In order to achieve the effect of the mounting seat 21 moving along the height direction of the support frame 2, refer to Figure 1The lifting assembly 3 includes a lifting slide bar 31, a lifting screw rod 32 and a lifting motor 33. The lifting motor 33 is mounted on the top of the support frame 2, the output shaft of the lifting motor 33 is welded to the top of the lifting screw rod 32, the bottom end of the lifting screw rod 32 is rotatably connected to the support frame 2, and the lifting screw rod 32 is threadedly connected to the mounting seat 21. The lifting slide bar 31 is arranged in parallel with the lifting screw rod 32, the lifting slide bar 31 passes through the mounting seat 21, and the ends of the lifting screw rod 32 are welded to the support frame 2. The lifting motor 33 drives the lifting screw rod 32 to rotate, and the lifting slide bar 31 makes it difficult for the mounting seat 21 to rotate synchronously with the lifting screw rod 32, thereby causing the mounting seat 21 to move along the height direction of the support frame 2, thereby achieving the effect of moving the air cannon 5 along the height direction.

[0037] In order to facilitate the sealing cover plate 12 to seal or expose the end of the air supply pipe 11, refer to Figure 1, a connecting seat 61 is installed on the air supply pipe 11, and a connecting sleeve 6 is rotated on the connecting seat 61 toward the side of the support frame 2, and a connecting rod 62 is welded between the side wall of the connecting sleeve 6 and the side wall of the sealing cover plate 12. A driving sleeve 7 is inserted in the connecting sleeve 6, and a limiting rod 9 is inserted in the driving sleeve 7. One end of the limiting rod 9 is welded to the connecting seat 61, and the other end of the limiting rod 9 is located in the connecting sleeve 6. Under the limiting effect of the connecting seat 61, the limiting rod 9 and the connecting sleeve 6 are not easy to move in the horizontal direction. A limiting groove 91 is provided on the outer wall of the limiting rod 9 in the horizontal direction, and a limiting block 92 is slidably provided in the limiting groove 91, and the limiting block 92 is welded to the inner wall of the driving sleeve 7. Under the limiting effect of the limiting rod 9, the driving sleeve 7 and the connecting seat 61 are not easy to rotate relative to each other. A reset spring 8 is sleeved on the limit rod 9, and one end of the reset spring 8 is welded to the connecting seat 61, and the other end of the reset spring 8 is welded to one end of the driving sleeve 7. One end of the drive sleeve 7 connected to the reset spring 8 is located in the connection sleeve 6, and the other end of the drive sleeve 7 protrudes from the connection sleeve 6. The end of the drive sleeve 7 protruding from the connection sleeve 6 is used to abut against the output pipe 51. The inner wall of the connection sleeve 6 is provided with a drive groove 72, and the drive groove 72 includes a spiral section and a straight section, and the spiral section and the straight section are connected. The angle between the two ends of the spiral section relative to the axis of the connection sleeve 6 is 180°, and there is a relative distance between the two ends of the spiral section in the axial direction. While the spiral section extends circumferentially along the inner wall of the connection sleeve 6, the spiral section extends axially along the inner wall of the connection sleeve 6. The angle between the two ends of the spiral section relative to the axis of the connection sleeve 6 is 0°, and there is a relative distance between the two ends of the straight section in the axial direction, and the straight section is arranged in the horizontal direction. A drive ball 71 rolls in the drive groove 72, and the drive ball 71 is rotatably connected to the outer wall of the drive sleeve 7. When the drive sleeve 7 moves in the horizontal direction, the limit block 92 on the drive sleeve 7 moves along the limit groove 91, and the drive ball 71 on the drive sleeve 7 rolls along the drive groove 72. When the driving ball 71 rolls along the straight section, the driving sleeve 7 and the connecting sleeve 6 only move relative to each other in the horizontal direction, and the connecting sleeve 6 does not rotate at this time; when the driving ball 71 rolls along the spiral section, the driving ball 71 not only moves relative to the connecting sleeve 6 in the axial direction, but also moves relative to the connecting sleeve 6 in the circumferential direction, so the driving sleeve 7 forces the connecting sleeve 6 to rotate. When the air cannon 5 drives the output pipe 51 to move toward the hopper 1, after the output pipe 51 abuts against the driving sleeve 7, the output pipe 51 will continue to approach the hopper 1. At this time, the output pipe 51 pushes the driving sleeve 7 to move toward the hopper 1, and the driving sleeve 7 forces the connecting sleeve 6 to rotate forward, so that the connecting sleeve 6 drives the sealing cover plate 12 to rotate to expose the port of the air supply pipe 11. When the air cannon 5 drives the output pipe 51 to move toward the support seat, the reset spring 8 pushes the driving sleeve 7 to move toward the support seat, and the driving sleeve 7 forces the connecting sleeve 6 to reverse, so that the connecting sleeve 6 drives the sealing cover plate 12 to rotate to close the port of the air supply pipe 11.

[0038] In order to facilitate the connection between the output pipe 51 and the gas supply pipe 11, refer to Figure 1The guide tube 52 is connected to the end of the output tube 51 away from the air cannon 5. The guide tube 52 is conical, and the outer diameter of the end of the guide tube 52 close to the output tube 51 is larger than the outer diameter of the end of the guide tube 52 away from the output tube 51. The air supply pipe 11 is provided for the guide tube 52 to be inserted, and the outer wall of the guide tube 52 is used to abut against the inner wall of the air supply pipe 11. When the port of the air supply pipe 11 is exposed, the output tube 51 drives the guide tube 52 to move and be inserted into the air supply pipe 11. When the outer wall of the guide tube 52 abuts against the inner wall of the air supply pipe 11, the air cannon 5 stops moving, and the air cannon 5 is started.

[0039] The implementation principle of a silo that is convenient for cleaning sticky materials in an embodiment of the present application is as follows: during the upward movement of the mounting seat 21, when the air cannon 5 moves to a position relative to a certain air supply pipe 11, the electric telescopic rod 4 drives the air cannon 5 to move toward the hopper 1. During the movement of the air cannon 5 toward the hopper 1, the sealing cover plate 12 relative to the air cannon 5 exposes the port of the air supply pipe 11. When the air cannon 5 located at the relative position is connected to the air supply pipe 11, the air cannon 5 is started to generate an impact force on the inside of the hopper 1 to form a cleaning effect, and then the electric telescopic rod 4 drives the air cannon 5 to move toward the support frame 2 to reset. When the output pipe 51 is separated from the air supply pipe 11, the sealing cover plate 12 again closes the end of the air supply pipe 11 away from the hopper 1, so that the material in the hopper 1 is not easy to leak out through the air supply pipe 11. When the hopper 1 is loading, unloading and storing materials normally, the mounting seat 21 is stationary at a position close to the bottom support frame 2. At this time, the output pipe 51 is separated from the air supply pipe 11, and the sealing cover plate 12 seals the end of the air supply pipe 11 away from the hopper 1, so that the material in the hopper 1 is not easy to leak out through the air supply pipe 11. When the hopper 1 is cleared, the mounting seat 21 drives the electric telescopic rod 4 and the air cannon 5 to move from bottom to top, so that the air supply pipe 11 on the hopper 1 is connected with the air cannon 5 from bottom to top to complete the clearing operation. Therefore, when the height of the hopper 1 is relatively high, the air cannon 5 clears the different height areas of the hopper 1 from bottom to top, reducing the situation of manual entry into the silo to clear the materials, so as to facilitate the cleaning of the inside of the silo.

[0040] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
