Description

Technical Field

[0001] This utility model relates to the field of rotary valve technology, and more specifically, to a high-temperature rotary valve for conveying powder materials. Background Technology

[0002] A rotary valve is a device that uses rotating parts within the valve body to convey materials. It is also called a valve shut-off valve, unloader, or airlock valve. It is divided into three main categories: ordinary type, pressure-resistant type, and high-temperature resistant type. It is widely used in industrial and food fields and can convey powdery and fluid materials. There are various types of high-temperature rotary valves for powder conveying on the market.

[0003] The existing rotating parts are prone to material buildup at the connection with the valve body, which is easy for the material to deteriorate. Furthermore, the overall disassembly and assembly are inconvenient, and the repair and maintenance are cumbersome when internal damage occurs.

[0004] A search revealed that Chinese patent application number CN202222215619.7 discloses a high-temperature rotary valve for powder conveying. This utility model is equipped with a first clamp, an installation rod, and a second clamp. The first clamp is rotatably connected to the installation rod on the left side, and an adjustment handle is threadedly connected to the outside of the installation rod. The adjustment handle can push the limit block to move. The second clamp is slotted to the outside of the connecting rod and the connecting shaft. Clamps are provided at both ends to facilitate the disassembly and maintenance of the rotary valve.

[0005] However, in actual use, the material may adhere to the blades of the high-temperature rotary valve during the material conveying process, which reduces the conveying efficiency of the rotary valve and increases the number of maintenance and cleaning operations, thus reducing the working efficiency of the rotary valve. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a high-temperature rotary valve for powder conveying to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A high-temperature rotary valve for powder conveying includes a valve body, a first valve cover inserted into one side of the valve body, and a second valve cover inserted into the other side of the valve body. Both the first and second valve covers are threaded with screws on their outer sides. A limit ring is provided inside the second valve cover, and multiple auxiliary balls are rotatably connected inside the limit ring. The outer sides of the multiple auxiliary balls are rotatably connected to the inner wall of the second valve cover. An auxiliary feeding mechanism is provided on one side of the first valve cover. The auxiliary feeding mechanism includes a positioning plate, one side of which is threaded to the outer side of the first valve cover. A motor is fixedly mounted on one side of the positioning plate, and a rotating shaft is fixedly connected to the output end of the motor. A limit block is fixedly connected to one side of the rotating shaft, and a rotating cylinder is fixedly connected to the outer side of the rotating shaft. Multiple partitions are fixedly connected to the outer side of the rotating cylinder, and two first guide rails are fixedly connected to one side of each partition.

[0009] By adopting the above technical solution, when installing the motor and the partition, the limit block and the limit ring inside the second valve cover and multiple auxiliary balls can be used to lock them together, so that the rotating shaft, rotating cylinder and multiple partitions can maintain stable rotation inside the valve body.

[0010] As a further description of the above technical solution: A first spring is provided on the outer side of the first guide rail, the bottom end of the first spring is fixedly connected to the inner wall of the partition, a first slider is fixedly connected to the top end of the first spring, a first baffle is hinged to the outer side of the first slider, two second guide rails are fixedly connected to the other side of the partition, a second spring is provided on the outer side of the second guide rail, the bottom end of the second spring is fixedly connected to the inner wall of the partition, a second slider is fixedly connected to the top end of the second spring, a second baffle is hinged to the outer side of the second slider, and two grooves are opened on the outer side of the second baffle.

[0011] By adopting the above technical solution, the first baffle and the second baffle between the two partitions can assist in pushing the raw materials during transportation, avoiding the raw materials from sticking to the drum and partitions during transportation, and improving the efficiency of raw material transportation.

[0012] As a further description of the above technical solution: an anti-clogging mechanism is provided on the outside of the valve body. The anti-clogging mechanism includes a base plate, an air pump is fixedly connected to the top of the base plate, a conduit is fixedly connected to the output end of the air pump, a valve is installed on the outside of the conduit, and a nozzle is fixedly connected to one end of the conduit.

[0013] By adopting the above technical solution, the raw materials that are not being conveyed and are piled up inside the valve body can be dispersed by gas, so that the raw materials can be quickly conveyed through the rotary valve.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. By setting an auxiliary feeding mechanism, compared with the existing technology, the raw materials can be directly pushed out from the two partitions during the process of conveying the raw materials out of the rotary valve, avoiding the accumulation and sticking of raw materials between the drum and the partitions, which can improve the efficiency of raw material conveying, while enhancing the service life of the rotary valve and reducing the frequency of disassembly and cleaning of the rotary valve.

[0016] 2. By setting up an anti-blocking mechanism, compared with existing technologies, it is possible to avoid the situation where raw materials accumulate and clump together after the rotary valve is closed. The accumulated raw materials can be dispersed by air pressure, allowing the raw materials to be smoothly conveyed through the rotary valve, thus improving the stability of the rotary valve in use.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This application discloses a high-temperature rotary valve for powder conveying, comprising a valve body 1, a first valve cover 2 inserted into one side of the valve body 1, and a second valve cover 3 inserted into the other side of the valve body 1. Both the first valve cover 2 and the second valve cover 3 are threadedly connected to the outer sides with screws 4. A limit ring 5 is provided inside the second valve cover 3, and multiple auxiliary balls 6 are rotatably connected inside the limit ring 5. The outer sides of the multiple auxiliary balls 6 are rotatably connected to the inner wall of the second valve cover 3. An auxiliary feeding mechanism is provided on one side of the first valve cover 2; the auxiliary feeding mechanism includes a positioning plate 7, one side of which is threadedly connected to the outer side of the first valve cover 2, and the other side of the positioning plate 7 is fixedly installed. There is a motor 8, and a rotating shaft 9 is fixedly connected to the output end of the motor 8. A limiting rotating block 10 is fixedly connected to one side of the rotating shaft 9. A rotating cylinder 11 is fixedly connected to the outside of the rotating shaft 9. Multiple partitions 12 are fixedly connected to the outside of the rotating cylinder 11. Two first guide rails 13 are fixedly connected to one side of the partitions 12. When the rotating cylinder 11 and the partitions 12 are installed inside the valve body 1, the limiting rotating block 10 can be inserted into the inside of the second valve cover 3. The limiting ring 5 and multiple auxiliary balls 6 limit the rotation of the limiting rotating block 10, so that when the motor 8 drives the rotating shaft 9 and the rotating cylinder 11 to rotate, the rotation can be kept stable.

[0027] Reference Figure 6 and Figure 7 As shown, a first spring 14 is provided on the outer side of the first guide rail 13. The bottom end of the first spring 14 is fixedly connected to the inner wall of the partition 12. A first slider 15 is fixedly connected to the top end of the first spring 14. A first baffle 16 is hinged to the outer side of the first slider 15. Two second guide rails 17 are fixedly connected to the other side of the partition 12. A second spring 18 is provided on the outer side of the second guide rail 17. The bottom end of the second spring 18 is fixedly connected to the inner wall of the partition 12. A second slider 19 is fixedly connected to the top end of the second spring 18. A second baffle 20 is hinged to the outer side of the second slider 19. Two grooves 21 are formed on the outer side of the second baffle 20. The first baffle 16 and the second baffle 20 between the two partitions 12 are pressed together, so that the first baffle 16 and the second baffle 20 can slide down alternately, allowing the raw material to be placed between the partitions 12. Then, as the partitions 12 rotate, the raw material between the two partitions 12 rotates to the bottom. The first spring 14 and the second spring 18 push the first slider 15 and the second slider 19, so that the raw material between the two partitions 12 can be pushed downward by the first baffle 16 and the second baffle 20 after being conveyed by the rotary valve, reducing the amount of raw material sticking to the outside of the partitions 12.

[0028] Reference Figure 1 As shown, an anti-blocking mechanism is provided on the outside of the valve body 1. The anti-blocking mechanism includes a base plate 22. An air pump 23 is fixedly connected to the top of the base plate 22. A conduit 24 is fixedly connected to the output end of the air pump 23. A valve 25 is installed on the outside of the conduit 24. A nozzle 26 is fixedly connected to one end of the conduit 24. When the valve 25 is opened, the air pump 23 disperses the raw material inside the valve body 1 through the conduit 24 and the nozzle 26, so that the raw material can pass through the rotary valve more smoothly.

[0029] The working principle of this utility model is as follows: During the process of conveying powdered raw materials through a high-temperature rotary valve, after the raw materials enter the valve body 1, the motor 8 drives the rotating shaft 9 to rotate. The limiting block 10 at one end of the rotating shaft 9 engages with the limiting ring 5 and multiple auxiliary balls 6 inside the second valve cover 3, allowing the limiting block 10 to rotate smoothly with the assistance of the multiple auxiliary balls 6. Then, as the raw materials come into contact with the multiple partitions 12 on the outside of the rotating drum 11, they squeeze the first baffle 16 and the second baffle 20 between the partitions 12. The first baffle 16 and the second baffle 20 slide against each other. Next, the first baffle 16 and the second baffle 20 move downwards via the first slider 15 and the second slider 19 on both sides, so that the raw material can be fully filled between the two partitions 12. Then, when the rotating shaft 9 drives the rotating drum 11 and the two partitions 12 containing the raw material to rotate downwards, the first spring 14 and the second spring 18 compressed on the outside of the first guide rail 13 and the second guide rail 17 push the first slider 15 and the second slider 19 respectively, so that the first baffle 16 and the second baffle 20 can push the raw material piled on the surface downwards during the rotation, reducing the accumulation of raw material inside the rotary valve.

[0030] When the rotary valve is not in operation, if too much material accumulates inside, valve 25 will open and air pump 23 will flush the material inside the rotary valve through conduit 24 and nozzle 26 to reduce the accumulation of material and facilitate material transportation.
