Technical Field

[0001] This utility model belongs to the technical field of anti-clogging devices, and more specifically, it relates to an anti-clogging device for the bottom outlet of a powder silo. Background Technology

[0002] A powder silo is a device used to store powdery materials, widely used in industries such as building materials, chemicals, metallurgy, and food. Its main function is to store and transport powdery materials such as cement, lime, and pulverized coal. A powder silo typically consists of a silo body, inlet, outlet, venting system, and auxiliary equipment. The silo body is usually made of steel or concrete, featuring good sealing, moisture resistance, and dustproofing. Depending on the requirements, powder silos can be equipped with vibrators, fluidizing devices, etc., to prevent material agglomeration or blockage; scrapers and arch breakers are also used for anti-blockage purposes.

[0003] Based on the above, the inventors have identified the following problems: In current applications of scraper arch breakers, due to differences in the physical properties (such as particle size, moisture content, and viscosity) of the materials within the powder silo, different types of scrapers are often required to achieve the best arch-breaking effect. However, existing scrapers are mostly installed using bolt fastening, which leads to cumbersome disassembly and time-consuming processes during scraper replacement, reducing equipment maintenance efficiency and affecting production continuity. It is recommended to optimize the scraper connection method by adopting a quick-change structure design to improve the convenience and efficiency of scraper replacement.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a device to prevent blockage at the bottom outlet of the powder silo, in order to achieve a more practical purpose. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an anti-clogging device for the bottom outlet of the powder silo, so as to solve the problem that it is troublesome to replace the scraper in the current scraper arch breaker.

[0006] The purpose and effect of this utility model's anti-clogging device for the bottom outlet of a powder silo are achieved by the following specific technical means:

[0007] A device for preventing blockage at the bottom outlet of a powder silo includes a powder silo body, an outlet on the surface of the powder silo body, a first flange installed at the bottom of the outlet, an arch breaker body installed at the bottom of the first flange, and a scraper installed on the surface of the arch breaker body via a quick-release mechanism.

[0008] Furthermore, the quick-release mechanism includes a mounting component with a placement groove on its surface. A first limiting block is installed in the placement groove. It also includes a first limiting groove installed on the surface of the scraper, which matches the first limiting block. One end of the scraper with the first limiting groove is located within the placement groove. A rotating plate is hinged to the surface of the mounting component. A first mounting plate is mounted on the surface of the mounting component, and a second mounting plate is mounted on the surface of the rotating plate. A first slot is formed on the surface of the first mounting plate, and a second slot is formed on the surface of the second mounting plate. A pressing component is installed within the first slot. A connecting plate is mounted on the top of the pressing component. A locking block is mounted on the surface of the connecting plate, located within the second slot. A blocking component is mounted on the bottom of the pressing component. A spring is sleeved on the surface of the pressing component, with one end of the spring contacting the blocking component and the other end contacting the bottom of the first mounting plate.

[0009] Furthermore, the main body of the arch breaker includes a mounting box, with second flanges installed at both ends of the mounting box, a worm gear installed inside the mounting box, and a slot opened on the surface of the mounting box. It also includes a motor installed on the surface of the mounting box, with a worm installed at the output end of the motor, and a portion of the worm passing through the slot and meshing with the worm gear.

[0010] Furthermore, a protective shell is installed on the surface of the motor, and the worm gear is located inside the protective shell.

[0011] Furthermore, a sealing cover is provided on the top of the powder hopper body.

[0012] Furthermore, the surface of the powder hopper body is coated with an anti-rust coating.

[0013] Furthermore, a second limiting block is installed in the first slot, and a second limiting groove is formed on the surface of the pressing member, with the second limiting block located in the second limiting groove.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This utility model utilizes the combined use of a powder silo body, a discharge port, a first flange, an arch breaker body, and a quick-release mechanism. In use, the arch breaker body can be connected to the first flange, and a control valve can be installed at the bottom of the arch breaker body. When it is necessary to replace the scraper inside the arch breaker body, the control valve can be removed, followed by the removal of the arch breaker body. Then, the pressing component is pushed, causing the connecting plate to move, which in turn causes the locking block to move. When the locking block disengages from the second slot, the rotating plate can be rotated to remove the scraper. A new scraper is then installed by aligning the first limiting groove on the scraper with the first limiting block. The pressing component is then pushed again, causing the spring to contract as it moves. The rotating plate is then closed, and the pressing component is released. The spring returns to its original position, causing the locking block to engage with the second slot on the surface of the second mounting plate. This design allows for quick scraper replacement, improving practicality. Attached Figure Description

[0029] Example:

[0030] As attached Figure 1 To be continued Figure 5 As shown:

[0031] This utility model provides a device for preventing blockage at the bottom outlet of a powder silo, including a powder silo body 1, an outlet 2 on the surface of the powder silo body 1, a first flange 3 installed at the bottom of the outlet 2, an arch breaker body 4 installed at the bottom of the first flange 3, and a scraper 6 installed on the surface of the arch breaker body 4 through a quick-release mechanism 5.

[0032] The quick-release mechanism 5 includes a mounting component 501, on the surface of which a placement groove 502 is formed. A first limiting block 503 is installed in the placement groove 502. It also includes a first limiting groove 504 installed on the surface of the scraper 6, which matches the first limiting block 503. One end of the scraper 6 with the first limiting groove 504 is located in the placement groove 502. A rotating plate 505 is hinged to the surface of the mounting component 501. A first mounting plate 506 is mounted on the surface of the mounting component 501, and a second mounting plate 507 is mounted on the surface of the rotating plate 505. The surface of the first mounting plate 506 has a first slot 508, and the surface of the second mounting plate 507 has a second slot 509. A pressing member 5010 is installed in the first slot 508. A connecting plate 5011 is installed on the top of the pressing member 5010. A locking block 5012 is installed on the surface of the connecting plate 5011. The locking block 5012 is located in the second slot 509. A blocking member 5013 is installed at the bottom of the pressing member 5010. A spring 5014 is sleeved on the surface of the pressing member 5010. One end of the spring 5014 is in contact with the blocking member 5013, and the other end is in contact with the bottom of the first mounting plate 506.

[0033] The components of the powder silo body 1, discharge port 2, first flange 3, arch breaker body 4, and quick-release mechanism 5 work together. During use, the arch breaker body 4 can be connected to the first flange 3. A control valve is then installed at the bottom of the arch breaker body 4. When the scraper 6 inside the arch breaker body 4 needs to be replaced, the control valve can be removed, and then the arch breaker body 4 can be removed. Then, the pressing component 5010 is pushed. The movement of the pressing component 5010 will cause the connecting plate 5011 to move, and the movement of the connecting plate 5011 will cause the locking block 5012 to move. When the locking block 5012 disengages from the second slot 5... At 09:00, the rotating plate 505 can be rotated, and the scraper 6 can be removed and replaced with a new scraper 6. Align the first limiting groove 504 on the scraper 6 with the first limiting block 503 for installation. Then push the pressing member 5010 again. When the pressing member 5010 moves, the spring 5014 will contract. Then close the rotating plate 505 and release the pressing member 5010. The spring 5014 will reset and drive the locking block 5012 to engage in the second slot 509 on the surface of the second mounting plate 507. Through the above design, the scraper 6 can be replaced quickly, improving practicality.

[0034] The main body 4 of the arch breaker includes a mounting box 401, with second flanges 402 installed at both ends of the mounting box 401. A worm gear 403 is installed inside the mounting box 401, and a slot 404 is opened on the surface of the mounting box 401.

A worm 406 is installed at the output end of the motor 405, and part of the worm 406 passes through the slot 404 and meshes with the worm gear 403.

[0035] With the above design, when the main body 4 of the arch breaker needs to be used, the motor 405 can be started. The start of the motor 405 will drive the worm gear 403 to rotate. The rotation of the worm gear 403 will drive the scraper 6 to rotate through the quick release mechanism 5, thereby avoiding blockage of the inner wall of the powder silo body 1.

[0036] The motor 405 is covered with a protective shell 7, and the worm gear 406 is located inside the protective shell 7.

[0037] The worm gear 406 can be protected by using the protective shell 7.
