An arch-breaking device for hard gypsum powder storage silos

Abstract

This utility model discloses an arch-breaking device for anhydrous gypsum powder storage silos, relating to the technical field of gypsum powder storage silos. It includes a discharge silo, with a moving device rotatably mounted on the outer surface of the discharge silo. The moving device includes a rotating frame, with lifting cylinders fixedly mounted on both sides inside the rotating frame. Lifting frames are fixedly mounted on the output ends of the lifting cylinders on both sides, and an arch-breaking component is fixedly mounted on the top of the lifting frame. In this arch-breaking device for anhydrous gypsum powder storage silos, the retraction of the lifting cylinders causes the rotating frame to rise inside the discharge nozzle. A top cone and scraper break up the clumps inside the discharge nozzle, preventing blockage at the discharge port and improving the discharge effect and efficiency of gypsum powder. The retraction of the pushing cylinder controls the descent of the lifting block, causing the lifting block to push a pushing rod to rotate. This push rod, in turn, drives a folding frame to rotate, causing the scraper to adhere to the inner wall of the silo. The rotation of the scraper breaks up the gypsum powder clumps on the inner wall of the silo, thereby expanding the arch-breaking range of the component.

Description

Technical Field

[0001] This utility model relates to the field of gypsum powder storage silos, and more specifically, to an arch-breaking device for hard gypsum powder storage silos. Background Technology

[0002] Anhydrite powder, a key raw material in building materials and chemical fillers, possesses strong hygroscopic properties and high interparticle adhesion. In industrial production, anhydrite powder typically requires transfer and storage in large storage silos to ensure continuous supply to the production line. These silos often employ a conical bottom structure, relying on the material's own gravity for discharge. Because anhydrite powder readily absorbs moisture from the air during storage, it can lead to particle clumping or the formation of "bridging" (i.e., a stable arched structure formed between the conical bottom and the discharge port within the silo). This phenomenon is known in the industry as "bridging."

[0003] During the production of gypsum powder, the processed gypsum powder needs to be stored in a storage silo. However, long-term storage of gypsum powder in the storage silo can cause internal clumping, making it difficult to discharge during the process. This can lead to blockage of the discharge port, making it inconvenient to use the gypsum powder and affecting the discharge effect and efficiency. Utility Model Content

[0004] The main purpose of this utility model is to provide an arch-breaking device for hard gypsum powder storage silos, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A device for breaking arches in a hard gypsum powder storage silo includes a discharge silo, wherein a moving device is rotatably mounted on the outer surface of the discharge silo.

[0013] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0014] As attached Figure 1 To be continued Figure 5 As shown, an embodiment of this utility model provides an arch-breaking device for a hard gypsum powder storage silo, including a discharge silo 1 and a moving device 2, wherein the moving device 2 is rotatably installed on the outer surface of the discharge silo 1. like Figure 3 As shown, the mobile device 2 includes a rotating frame 21 and an arch-breaking assembly 3. A rotating motor 22 is fixedly installed on the side of the rotating frame 21. A drive gear 23 is fixedly installed at the output end of the rotating motor 22. The drive gear 23 is rotatably installed on the upper end of the rotating frame 21. Lifting cylinders 24 are fixedly installed on both sides inside the rotating frame 21. Lifting frames 25 are fixedly installed at the output ends of the lifting cylinders 24 on both sides. The top of the lifting frames 25 is fixedly installed with the arch-breaking assembly 3.

[0015] like Figure 2 As shown, the discharge bin 1 includes a bin 11 and a discharge nozzle 12. The bottom of the bin 11 is fixedly connected to the discharge nozzle 12. Limiting frames 14 are fixedly installed at both the upper and lower ends of the discharge nozzle 12. A fixed gear 15 is fixedly sleeved on the outer surface of the upper end of the discharge nozzle 12. A gate valve 13 is provided on the top of the discharge nozzle 12.

[0016] The rotating frame 21 is rotatably mounted on the outer surface of the limiting frame 14, the outer surface of the driving gear 23 meshes with the outer surface of the fixed gear 15, the lifting frame 25 is movably sleeved inside the feeding nozzle 12, and the arch breaking component 3 is movably sleeved inside the feeding nozzle 12.

[0017] Specifically, when the rotary motor 22 controls the drive gear 23 to rotate, the outer surface of the drive gear 23 meshes with the outer surface of the fixed gear 15. When the drive gear 23 rotates, the rotating frame 21 rotates on the outer surface of the limiting frame 14, causing the arch-breaking assembly 3 to rotate inside the feed nozzle 12.

[0018] like Figure 4 As shown, the arch-breaking component 3 includes a fixed column 31, a folding frame 33, and a scraper 34. A bottom frame 32 is fixedly installed at the lower end of the fixed column 31, and four support frames are fixedly installed at the top of the bottom frame 32. Sliding grooves 35 are provided on all four sides of the top of the fixed column 31. A top cone 36 is fixedly installed at the top of the fixed column 31. A lifting block 37 is movably sleeved on the outer surface of the upper end of the fixed column 31. Push rods 38 are rotatably installed on all four sides of the lifting block 37. The sides of the four support frames are rotatably installed with the folding frame 33. One end of the push rod 38 is rotatably connected to the middle of the folding frame 33. The sides of the folding frame 33 are fixedly connected to the scraper 34.

[0019] The lower end of the fixed column 31 is fixedly installed with a push cylinder 39, the top of the push cylinder 39 is fixedly connected to the lifting block 37, and the lifting block 37 is slidably installed inside the sliding groove 35 and fixedly connected.

[0020] Specifically, the connection between the silo 11 and the discharge nozzle 12 adopts a conical bottom structure. The cylinder 39 is pushed to retract, and the lifting block 37 is controlled to descend. The lifting block 37 pushes the push rod 38 to rotate, and the push rod 38 pushes the folding frame 33 to rotate, so that the scraper 34 is attached to the inner wall of the silo 11. Through the rotation of the scraper 34, the gypsum powder on the inner wall of the silo 11 is broken up, thereby expanding the breaking range of the breaking component 3.

[0021] The working process of this utility model is as follows: In use, by opening the gate valve 13, the gypsum powder inside the tank 11 is discharged through the discharge nozzle 12 by gravity. When the gypsum powder inside the discharge nozzle 12 clumps together, the lifting cylinder 24 retracts, causing the rotating frame 21 to rise inside the discharge nozzle 12. The top cone 36 and the scraper 34 break up the clumps inside the discharge nozzle 12. When the arch-breaking component 3 enters the interior of the tank 11, it pushes the cylinder 39 to retract, controls the lifting block 37 to descend, and causes the lifting block 37 to push the push rod 38 to rotate. The push rod 38 then pushes the folding frame 33 to rotate, causing the scraper 34 to adhere to the inner wall of the tank 11. The rotary motor 22 controls the drive gear 23 to rotate. Through the meshing of the drive gear 23 and the fixed gear 15, when the drive gear 23 rotates, the rotating frame 21 rotates on the outer surface of the limit frame 14 and scrapes the inner wall of the tank 11 with the scraper 34 to break the arch of the gypsum powder.
