Description

Technical Field

[0001] This application relates to the field of storage equipment, and in particular to a dust-proof storage silo. Background Technology

[0002] Silos are key equipment in industrial production systems used for storing and transferring materials. In material manufacturing and other processes, silos use a steel structure that combines cubes and cones, and work with automated weighing systems to achieve continuous production.

[0003] To facilitate the transport of materials into the silo, a feed inlet is usually opened on the side wall of the silo, and the material is transported by a bucket and enters the silo through the feed inlet, thereby achieving rapid material transport.

[0004] However, for powdery materials, after the bucket pours the material into the hopper, the powder flies around and is easily blown out of the feed inlet, affecting the environment and causing material waste. Utility Model Content

[0005] In order to reduce the amount of material flying out through the feed inlet and keep the environment clean, this application provides a dust-proof storage silo.

[0006] The dust-proof storage silo provided in this application adopts the following technical solution:

[0007] A dust-proof storage silo includes a silo body with a feed inlet at the upper end of the silo body. A dust-proof mechanism is provided at the feed inlet. The dust-proof mechanism includes a dust-proof curtain that blocks the feed inlet. The silo body is also provided with a drive assembly for driving the dust-proof curtain.

[0008] By adopting the above technical solution, during feeding, the drive component drives the dustproof curtain to move, thereby opening the feed inlet and allowing the material to enter the silo through the feed inlet. After feeding is completed, the drive component immediately drives the dustproof curtain to close the feed inlet, thereby preventing dust from flying out through the feed inlet and protecting the environment.

[0009] Optionally, the number of dust-proof curtains is set to two. The drive assembly includes fixing clips at the four corners of the dust-proof curtains. Ball screws are provided on both the upper and lower sides of the dust-proof curtains. The threads at both ends of the ball screws are arranged in opposite directions. The fixing clips on the side of the two dust-proof curtains that are far apart from each other are fixed to the chamber body and are rotatably connected to the ball screws. The fixing clips on the side of the two dust-proof curtains that are close to each other are threadedly connected to the corresponding ball screws. The drive assembly also includes a drive component for pulling the dust-proof curtains.

[0010] By adopting the above technical solution, the driving component pulls the two dust curtains away from each other, causing the dust curtains to open. The dust curtains drive the fixed clamp to move, and the fixed clamp drives the ball screw to rotate during the movement, thereby making the two dust curtains move synchronously, thus realizing the synchronous opening and closing of the feed port.

[0011] Optionally, the driving component includes a drive motor mounted on the chamber body, a traction line on the output shaft of the drive motor, the traction line being fixed to the middle part of the dust curtain, and a spring sleeved on the ball screw, with the two ends of the spring respectively fixed to corresponding fixing clamps.

[0012] By adopting the above technical solution, the drive motor rotates, causing the traction line to wind around the output shaft of the drive motor, which in turn pulls the dust curtain, thus opening one dust curtain. At the same time, the ball screw opens the other dust curtain. When the drive motor unwinds, the spring drives the fixing clamp to return to its original position, thereby closing the feed inlet again.

[0013] Optionally, the feed inlet is also provided with a guide rod that corresponds to and is parallel to the ball screw. The guide rod passes through the corresponding fixing clamp. The dust curtain is provided with multiple through holes arranged in parallel. The guide rod passes through the through holes in the same row.

[0014] By adopting the above technical solution, the guide rod provides guidance for the fixing clamp and supports the middle part of the dust curtain, thereby enabling the dust curtain to be pulled and pushed smoothly.

[0015] Optionally, a dust suction port is provided at the top of the hopper, and a material discharge port is provided at the bottom of the hopper.

[0016] By adopting the above technical solution, when powder flies in the silo, the dust suction port sucks in air, thereby quickly expelling the dust and reducing the possibility of dust flying out through the feed port.

[0017] Optionally, magnetic blocks are provided on the sides of the two dust curtains that are close to each other, and the two dust curtains are fixedly connected by magnetic blocks.

[0018] By adopting the above technical solution, the sides of the two dust curtains are attracted together by magnetic blocks, which enables the dust curtains to seal the feed inlet more completely and reduce the possibility of dust diffusion.

[0019] Optionally, a fixed pulley is rotatably connected to the hopper body, and the traction line passes around the fixed pulley.

[0020] By adopting the above technical solution, the traction rope is deflected by pulleys, thereby reducing wear on the traction rope and extending its service life.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] The drive unit moves the dust-proof curtain, thereby opening the feed inlet and allowing the material to enter the silo. After feeding is completed, the drive unit immediately drives the dust-proof curtain to close the feed inlet, thereby preventing dust from flying out through the feed inlet and protecting the environment.

[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] This application discloses a dust-proof storage silo.

[0027] Reference Figure 1 A dust-proof storage silo includes a silo body 1. The upper end of the silo body 1 is cubic and the lower end is conical. A feed inlet 11 is provided on one side of the upper end of the silo body 1. A dust suction port 12 is provided at the top of the silo body 1 and communicates with the interior of the silo. A discharge port communicating with the interior of the silo body 1 is provided at the bottom of the silo body 1.

[0028] A dust-proof mechanism 2 is provided at the feed inlet 11. The dust-proof mechanism 2 includes a dust-proof curtain 21 that blocks the feed inlet 11. A drive assembly 22 for driving the dust-proof curtain 21 is also provided on the silo body 1.

[0029] During feeding, the drive assembly 22 moves the dust-proof curtain 21, thereby opening the feed inlet 11 and allowing the material to enter the silo 1 through the feed inlet 11. When powder flies in the silo, the suction port 12 draws in air, thereby quickly expelling the dust and reducing the possibility of dust flying out through the feed inlet 11. After feeding is completed, the drive assembly 22 immediately drives the dust-proof curtain 21 to close the feed inlet 11, thereby preventing dust from flying out through the feed inlet 11 and protecting the environment.

[0030] Two dust-proof curtains 21 are provided. The drive assembly 22 includes fixing clips 221 at the four corners of the dust-proof curtains 21. Magnetic blocks 211 are provided on the side of the two dust-proof curtains 21 that are close to each other, and the two dust-proof curtains 21 are fixedly connected by the magnetic blocks 211. Ball screws 222 are provided on both the upper and lower sides of the dust-proof curtains 21. The threads at both ends of the ball screws 222 are arranged in opposite directions. The fixing clips 221 on the side of the two dust-proof curtains 21 that are far from each other are fixed to the chamber body 1 and are rotatably connected to the ball screws 222. The fixing clips 221 on the side of the two dust-proof curtains 21 that are close to each other are threadedly connected to the corresponding ball screws 222. The drive assembly 22 also includes a drive component for pulling the dust-proof curtains 21.

[0031] The sides of the two dust curtains 21 are attracted together by magnetic blocks 211, so that the dust curtains 21 can seal the feed inlet 11 more completely. The driving component pulls one of the dust curtains 21 to open the feed inlet 11. At the same time, the fixed clamp 221 drives the ball screw 222 to rotate, so that the other fixed clamp 221 is driven by the ball screw 222, thereby opening the other dust curtain 21. Thus, the two dust curtains 21 move synchronously, thereby realizing the synchronous opening and closing of the feed inlet 11.

[0032] The driving component includes a drive motor 224 mounted on the chamber 1. The output shaft of the drive motor 224 is provided with a traction line 225, which is also fixed to the middle part of the dust curtain 21. A spring 226 is also sleeved on the ball screw 222, and the two ends of the spring 226 are respectively fixed to the corresponding fixing clips 221.

[0033] The drive motor 224 rotates, causing the traction line 225 to wind around the output shaft of the drive motor 224, which in turn pulls the dust curtain 21, thus opening one of the dust curtains 21. When the drive motor 224 unwinds, the spring 226 drives the fixing clamp 221 to return to its original position, thereby closing the feed inlet 11 again.

[0034] The feed inlet 11 is also equipped with a guide rod 223 that corresponds to and is parallel to the ball screw 222. The guide rod 223 passes through the corresponding fixing clamp 221. The dust curtain 21 has multiple through holes arranged side by side, and the guide rod 223 passes through the through holes in the same row. A fixed pulley 227 is rotatably connected to the hopper body 1, and the traction line 225 passes around the fixed pulley 227.

[0035] The guide rod 223 provides guidance for the fixing clamp 221 and supports the middle part of the dust curtain 21, thereby enabling the dust curtain 21 to be pulled and pushed smoothly. The traction rope is deflected by pulleys, thereby reducing wear on the traction rope and extending its service life.

[0036] The implementation principle of a dustproof storage silo in this application embodiment is as follows: When feeding is required, the drive motor 224 drives the dust curtain 21 to move, thereby opening the feed port 11. At this time, the bucket transports the material into the silo. After the bucket leaves the silo body 1, the drive motor 224 unwinds, causing the spring 226 to push the fixing clamp 221, and the two dust curtains 21 expand, thereby blocking the feed port 11. At the same time, the two dust curtains 21 are fixedly connected on one side close to each other by magnetic blocks 211.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
