Description

Technical Field

[0001] This application relates to the field of rotary valve technology, specifically a high-efficiency and durable powder anti-clogging rotary valve. 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] The existing rotary valve has the following problems when in use: 1. Powder can easily accumulate in the gap between the rotor blades and the valve body cavity, causing blockages, which can lead to increased transmission resistance or even jamming. 2. Sticky powder easily adheres to the rotor and inner wall, making it difficult to remove and affecting the accuracy of the rotary valve. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a highly efficient and durable powder anti-clogging rotary valve, which has the advantage of improving the conveying accuracy of rotary valves and solving the problem of inconvenient powder cleaning.

[0005] To achieve the above objectives, this application provides the following technical solution: a high-efficiency and durable powder anti-clogging rotary valve, comprising a rotary valve body, wherein the inlet and outlet of the rotary valve body are provided with cleaning mechanisms, and the inlet of the rotary valve body is provided with a crushing mechanism; The cleaning mechanism includes an air compressor, a first connecting pipe, a second connecting pipe, a cleaning box, a connecting sleeve, and a nozzle. The air compressor is installed on one side of the rotary valve body. One end of the first connecting pipe is connected to the air outlet of the air compressor, and one end of the second connecting pipe is connected to the first connecting pipe. The other ends of the first and second connecting pipes are respectively connected to two connecting sleeves. The two sets of cleaning boxes are respectively set at the inlet and outlet of the rotary valve body. The connecting sleeve is welded to the outside of the cleaning box and forms a communicating cavity with the cleaning box. The nozzle communicating cavity is installed inside the cleaning box.

[0006] Multiple nozzles at the top and bottom perform bidirectional and efficient cleaning of powder on the blades and the inner wall of the rotary valve body, preventing powder from accumulating in the gap between the rotor blades and the valve body cavity, thus preventing the rotary valve body from becoming clogged.

[0007] Preferably, electric valves are provided on the first connecting pipe and the second connecting pipe.

[0008] Preferably, a filter screen is provided on the inner side of the nozzle.

[0009] Preferably, several groups of the nozzles are symmetrically distributed inside the cleaning chamber.

[0010] Preferably, the crushing mechanism includes a drive motor, a connecting rod, and a three-claw crushing disc. The drive motor is installed on the outside of the cleaning box, one end of the connecting rod is fixedly connected to the output end of the drive motor, the other end of the connecting rod is rotatably connected to the inside of the cleaning box, and the three-claw crushing disc is fixedly connected to the outer surface of the connecting rod.

[0011] Preferably, several groups of the three-claw breaking pieces are linearly distributed on the outer surface of the connecting rod.

[0012] In summary, this application includes at least one of the following beneficial effects: 1. This high-efficiency and durable powder anti-clogging rotary valve uses compressed air to spray bidirectionally from multiple symmetrically distributed nozzles, which can effectively remove powder adhering to the rotor blades and the inner wall of the valve body, preventing powder from accumulating in the gaps. This avoids the problem of increased transmission resistance or even jamming caused by clogging, and achieves a high-efficiency and durable anti-clogging function.

[0013] 2. This high-efficiency and durable powder anti-clogging rotary valve uses a high-speed rotating three-jaw crusher to pre-crush the input powder, breaking up any possible powder clumps. This allows the material to enter the valve body in a more uniform and loose state, fundamentally reducing the risk of clogging and improving the feeding accuracy and operational stability of the rotary valve.

[0016] 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.

[0017] Please see Figure 1-4 A high-efficiency and durable powder anti-clogging rotary valve includes a rotary valve body 1, with cleaning mechanisms provided at the inlet and outlet of the rotary valve body 1, and a crushing mechanism provided at the inlet of the rotary valve body 1.

[0018] Through the above technical solution, the material is conveyed from the top of the rotary valve body 1 to the inside of the rotary valve body 1. When the powder on the material accumulates inside the rotary valve body 1, the powder can be efficiently cleaned by the cleaning mechanism.

[0019] Specifically, the cleaning mechanism includes an air compressor 111, a first connecting pipe 112, a second connecting pipe 113, a cleaning box 115, a connecting sleeve 116, and a nozzle 117. The air compressor 111 is installed on one side of the rotary valve body 1. One end of the first connecting pipe 112 is connected to the air outlet of the air compressor 111, and one end of the second connecting pipe 113 is connected to the first connecting pipe 112. The other ends of the first connecting pipe 112 and the second connecting pipe 113 are respectively connected to two connecting sleeves 116. Electric valves 114 are installed on the first connecting pipe 112 and the second connecting pipe 113. Two sets of cleaning boxes 115 are respectively installed at the inlet and outlet of the rotary valve body 1. The connecting sleeve 116 is welded to the outside of the cleaning box 115 and forms a communicating cavity with the cleaning box 115. The communicating cavity of the nozzle 117 is installed inside the cleaning box 115. Several sets of nozzles 117 are symmetrically distributed inside the cleaning box 115. A filter screen 118 is installed on the inner side of the nozzle 117.

[0020] With the above technical solution, when the powder adheres to the inside of the rotary valve body 1 and the blades, the air compressor 111 introduces air into the communicating cavity between the cleaning box 115 and the connecting sleeve 116 through the connecting pipe 112 and the connecting pipe 2 113. The air is discharged from the nozzle 117 and the air discharged from the nozzle 117 is continuously sprayed onto the blades inside the rotary valve body 1. Multiple nozzles 117 at the top and bottom perform bidirectional and efficient cleaning of powder on the blades and the inner wall of the rotary valve body 1, preventing powder from accumulating in the gap between the rotor blades and the valve body cavity, thus preventing the rotary valve body 1 from becoming clogged.

[0021] At the same time, the electric valve 114 can be opened and closed, allowing the electric valve 114 to connect and close the connecting pipe 112 and the connecting pipe 213. The filter 118 is used to prevent powder from entering the nozzle 117.

[0022] Specifically, the crushing mechanism includes a drive motor 211, a connecting rod 212, and a three-jaw crushing disc 213. The drive motor 211 is installed on the outside of the cleaning box 115. One end of the connecting rod 212 is fixedly connected to the output end of the drive motor 211, and the other end of the connecting rod 212 is rotatably connected to the inside of the cleaning box 115. The three-jaw crushing disc 213 is fixedly connected to the outer surface of the connecting rod 212, and several sets of three-jaw crushing discs 213 are linearly distributed on the outer surface of the connecting rod 212.

[0023] With the above technical solution, when the material is introduced into the cleaning box 115 above, the drive motor 211 is started. The drive motor 211 drives the connecting rod 212 to rotate, and the connecting rod 212 drives the three-jaw crusher 213 to rotate. When the three-jaw crusher 213 rotates, it crushes the powder, so that the material will not gather into clumps when it is introduced into the rotary valve body 1, allowing the rotary valve body 1 to convey the material more stably.

[0024] During use, the air discharged from the nozzle 117 is continuously sprayed onto the blades inside the rotary valve body 1. The multiple nozzles 117 above and below perform bidirectional and efficient cleaning of the powder on the blades and the inner wall of the rotary valve body 1, making it difficult for powder to accumulate in the gap between the rotor blades and the valve body cavity, thus preventing the rotary valve body 1 from becoming clogged.

[0025] 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.
