Description

Technical Field

[0001] This application relates to the field of rotary valve technology, specifically to an anti-clogging rotary valve for material feeding. Background Technology

[0002] Rotary valves, also known as unloaders, airlock valves, or rotary valves, are classified into three main types: ordinary, pressure-resistant, and high-temperature resistant. Rotary valves are installed at the discharge port of unloaders operating under negative pressure. The upper part receives the powder discharged from the unloader, and the rotating impeller serves both to transport the material and to provide a seal, preventing air from being drawn in through the discharge port during pneumatic conveying and ensuring normal material discharge from the unloader.

[0003] When the existing rotary valve is in use, the powder particles are small. If too much powder is added at once, it is easy for the powder to clump together and fall into the rotary valve. The clumps of powder can easily clog the rotary valve and affect its operation.

[0004] Therefore, there is an urgent need for an anti-clogging rotary valve to solve the problem of rotary valves being prone to clogging. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides an anti-clogging rotary valve for material feeding, which has the advantage of ensuring stable powder conveying and solves the problem of easy clogging of rotary valves.

[0006] To achieve the above objectives, this application provides the following technical solution: including a rotary valve body, a connecting box disposed on the top of the rotary valve body, and a feeding cylinder disposed on the top of the connecting box, characterized in that: a regulating mechanism is disposed inside the connecting box, and a crushing mechanism is disposed inside the feeding cylinder; The control mechanism includes a drive motor, a threaded rod, a threaded sleeve, and a baffle. The drive motor is located on one side of the connecting box. One end of the threaded rod is fixedly connected to the output end of the drive motor, and the other end of the threaded rod is rotatably connected to the inside of the connecting box. The threads on both sides of the threaded rod are in opposite directions. The threaded sleeve is threadedly connected to the outer surface of the threaded rod. One end of the threaded sleeve is welded to the baffle. The baffle is slidably connected to the inside of the connecting box. The two sets of baffles are close to or far apart to control the unloading amount. The crushing mechanism includes a second drive motor, a connecting rod, a connecting sleeve, a crushing disc, and a scraper. The second drive motor is installed on the outside of the feed cylinder. One end of the connecting rod is fixedly connected to the output end of the second drive motor, and the other end of the connecting rod is rotatably connected to the inside of the feed cylinder. The connecting sleeve is welded to the outer surface of the connecting rod, the crushing disc is welded to the outer surface of the connecting sleeve, and the scraper is welded to the outside of the crushing disc.

[0007] By adjusting the position of the two sets of threaded sleeves, the threaded sleeves drive the baffles to move closer or further apart, thereby adjusting the size of the discharge port inside the connecting box, thus controlling the amount of powder input into the rotary valve body, so that the powder will not clog the rotary valve body, allowing the rotary valve body to stably convey the powder.

[0008] Preferably, the top of the opposite ends of the baffles is an inclined surface, which is used to form a guide funnel when the baffles approach each other, so as to guide the material to fall in a concentrated manner.

[0009] The inclined surface makes it easier to guide the powder to fall.

[0010] Preferably, a partition plate is welded inside the connecting box at the position corresponding to the threaded sleeve, and the partition plate has a square groove adapted to the threaded sleeve.

[0011] Preferably, the threaded rod is connected to the connecting box via a bearing.

[0012] Preferably, the crushing mechanism includes a second drive motor, a connecting rod, a connecting sleeve, a crushing disc, and a scraper. The second drive motor is installed on the outside of the feed cylinder. One end of the connecting rod is fixedly connected to the output end of the second drive motor, and the other end of the connecting rod is rotatably connected to the inside of the feed cylinder. The connecting sleeve is welded to the outer surface of the connecting rod, the crushing disc is welded to the outer surface of the connecting sleeve, and the scraper is welded to the outside of the crushing disc.

[0013] Preferably, several groups of the connecting sleeves, crushing blades and scrapers are linearly distributed along the axis of the connecting rod.

[0014] In summary, this application includes at least one of the following beneficial effects: 1. This anti-clogging rotary valve has a crushing mechanism as the primary process, which crushes large pieces of material into uniform particles; and a regulating mechanism as the secondary process, which precisely controls the feed rate to prevent the crushed material from clogging at the feed inlet of the rotary valve body due to excessive instantaneous flow. The two mechanisms work together to systematically eliminate the risk of material blockage at the source.

[0015] 2. This anti-clogging rotary valve, when the powder enters the feed cylinder through the pipeline, the connecting rod drives the connecting sleeve to rotate, and the connecting sleeve drives the crushing blade and scraper to rotate. When the crushing blade and scraper rotate, they crush the lumps of powder and disperse the powder into powder, which will not clog the pipeline and the rotary valve body, allowing the powder to be transported conveniently.

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] Please see Figure 1-4 A rotary valve for preventing material blockage includes a rotary valve body 1, a connecting box 2 disposed on the top of the rotary valve body 1, and a feed cylinder 3 disposed on the top of the connecting box 2. The rotary valve body 1 is driven by an external drive structure to rotate the impeller inside the rotary valve body 1, thereby conveying materials. The connecting box 2 is equipped with a control mechanism, and the feed cylinder 3 is equipped with a crushing mechanism. The material is introduced into the feed cylinder 3 through an external pipe and crushed by the crushing mechanism. The crushed powder enters the connecting box 2 and is controlled by the control mechanism inside the connecting box 2 to ensure stable feeding of the powder into the rotary valve body 1.

[0020] Specifically, the control mechanism includes a drive motor 111, a threaded rod 112, a threaded sleeve 113, and a baffle 114. The drive motor 111 is located on one side of the connecting box 2. One end of the threaded rod 112 is fixedly connected to the output end of the drive motor 111, and the other end of the threaded rod 112 is rotatably connected to the inside of the connecting box 2. The threads on both sides of the threaded rod 112 are in opposite directions. The threaded sleeve 113 is threadedly connected to the outer surface of the threaded rod 112. The threaded rod 112 is connected to the connecting box 2 through a bearing. One end of the threaded sleeve 113 is welded to the baffle 114. The baffle 114 is slidably connected to the inside of the connecting box 2. The two sets of baffles 114 are close to or far apart to control the discharge volume. The top of the opposite end of the baffle 114 is an inclined surface. The inclined surface is used to form a guide funnel when the baffles 114 are close to each other to guide the material to fall in a concentrated manner.

[0021] With the above technical solution, when the crushed powder enters the connecting box 2, the drive motor 111 is started. The drive motor 111 drives the threaded rod 112 to rotate. When the threaded rod 112 rotates, it drives the threaded sleeve 113 to move. By adjusting the position of the two sets of threaded sleeves 113, the threaded sleeves 113 drive the baffle 114 to move closer or further away from each other, thereby adjusting the size of the discharge port inside the connecting box 2, thereby controlling the amount of powder input into the rotary valve body 1, so that the powder will not block the rotary valve body 1, and the rotary valve body 1 can stably convey the powder.

[0022] Specifically, a partition plate 115 is welded inside the connecting box 2 at the position corresponding to the threaded sleeve 113, and a square groove adapted to the threaded sleeve 113 is opened on the partition plate 115.

[0023] Through the above technical solution, the threaded sleeve 113 slides in the square grooves on both sides of the partition 115. When the threaded sleeve 113 moves, it drives the baffle 114 to move, thereby controlling the size of the feed inlet formed by the two sets of baffles 114. The partition 115 can prevent the powder from entering the cavity inside the connecting box 2 of the threaded rod 112, affecting the rotation of the threaded rod 112.

[0024] Specifically, the crushing mechanism includes a second drive motor 211, a connecting rod 212, a connecting sleeve 213, crushing discs 214, and scrapers 215. The second drive motor 211 is installed on the outside of the feed cylinder 3. One end of the connecting rod 212 is fixedly connected to the output end of the second drive motor 211, and the other end of the connecting rod 212 is rotatably connected to the inside of the feed cylinder 3. The connecting sleeve 213 is welded to the outer surface of the connecting rod 212, the crushing discs 214 are welded to the outer surface of the connecting sleeve 213, and the scrapers 215 are welded to the outside of the crushing discs 214. Several sets of connecting sleeves 213, crushing discs 214, and scrapers 215 are linearly distributed along the axial direction of the connecting rod 212.

[0025] With the above technical solution, when the powder enters the feed cylinder 3 through the pipeline, the second drive motor 211 is started. The second drive motor 211 drives the connecting rod 212 to rotate, the connecting rod 212 drives the connecting sleeve 213 to rotate, and the connecting sleeve 213 drives the crushing disc 214 and the scraper 215 to rotate. When the crushing disc 214 and the scraper 215 rotate, they crush the lumps of powder and disperse the powder into powder. This will not block the pipeline and the rotary valve body 1, allowing the powder to be transported conveniently. Through the control of the crushing and regulating mechanisms, the crushed powder can be stably conveyed into the rotary valve body 1.

[0026] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
