Technical Field

[0001] The utility model relates to the technical field of rotary valves, in particular to a transverse acceleration chamber for a rotary valve. Background Art

[0002] The rotary valve is used to be installed at the discharge port of the discharger working under negative pressure. The upper part receives the material discharged by the discharger, and relies on the rotating impeller to convey the material. It also plays a sealing role to prevent air from being sucked into the discharge port during pneumatic conveying, ensuring the normal discharge of the discharger. As a special unloading equipment, it plays a great role in cleaning and washing work, and is widely used in pneumatic transportation and unloading of pipe network pressure state of equipment in industries such as rice milling, flour making, feed, machinery and chemical industry, medicine, tobacco, metallurgy, cement and dust removal.

[0003] Existing rotary valves usually use rotor rotation to transport materials during the conveying process. However, since the rotor speed is constant and the conveyed material is limited, when there is too much material, it is easy to cause blockage in the rotary valve, and the conveying efficiency is low, which cannot meet the needs of society. Therefore, a rotary valve with a transverse acceleration chamber is proposed to solve the above problems. Utility Model Content

[0006] The working mechanism includes a rotating shaft, a rotating shaft is fixedly installed at the output end of the reducer, a rotor is arranged on the surface of the rotating shaft, a feed port is arranged on the top of the valve body, an acceleration chamber is arranged inside the acceleration box, an air inlet is arranged on the right side of the acceleration box, a discharge port is arranged on the left side of the acceleration box, an electric telescopic rod is fixedly installed on the inner wall of the acceleration box, a fixed block is fixedly installed on the inner wall of the acceleration box, and an acceleration plate is movably installed on the surface of the fixed block.

[0007] Furthermore, the valve body and the acceleration box are fixedly installed by means of threads, and the valve body is communicated with the inside of the acceleration box.

[0008] Furthermore, a chain and a reduction gear set are arranged inside the reducer, and the chain and the gear set are installed through meshing transmission.

[0009] Furthermore, the rotor rotates counterclockwise, and the center of the fixing block and the center of the air inlet are in the same horizontal plane.

[0010] Furthermore, the internal contour size of the air inlet is consistent with the internal contour size of the discharge port, and a sealing component is provided inside the sealing end cover.

[0011] Furthermore, the acceleration plate and the fixing block are movably mounted in a hinged manner, and the acceleration plate and the electric telescopic rod and the acceleration plate are movably mounted in a hinged manner.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0013] 1. The rotary valve uses a transverse acceleration chamber, and a working mechanism is arranged inside the valve body. The device uses an electric telescopic rod to adjust the inclination angle of the acceleration plate and an external source is introduced at the air inlet.

[0022] The working mechanism 5 includes a rotating shaft 501, the rotating shaft 501 is fixedly installed at the output end of the reducer 4, a rotor 502 is arranged on the surface of the rotating shaft 501, and the rotor 502 can bring the material at the feed port 503 into the interior of the acceleration box 3 by rotating counterclockwise, the top of the valve body 2 is provided with a feed port 503, the interior of the acceleration box 3 is provided with an acceleration chamber 504, the right side of the acceleration box 3 is provided with an air inlet 505, the left side of the acceleration box 3 is provided with a discharge port 506, the inner wall of the acceleration box 3 is fixedly installed with an electric telescopic rod 507, and the inner wall of the acceleration box 3 is fixedly installed with a fixed block 5 08. Since the fixed block 508 is hinged with the acceleration plate 509, the angle adjustment of the acceleration plate 509 is facilitated. The acceleration plate 509 is movably installed on the surface of the fixed block 508. Under the electric telescopic traction of the electric telescopic rod 507, the acceleration plate 509 changes the inclination angle between the acceleration plate 509 and the air inlet 505, thereby adjusting the air pressure and flow rate on the upper and lower sides of the acceleration plate 509, which can reduce the contact area between the material and the inner wall of the acceleration box 3, avoid the accumulation of materials at the discharge port 506, and guide the air introduced from the outside to make the material transportation smoother and improve the transportation efficiency.

[0023] When implementing, follow these steps:

[0024] 1) First, the material is introduced from the feed port 503, and the rotor 502 rotates to drive the material into the acceleration chamber 504;

[0025] 2) Then the electric telescopic rod 507 is started, and the inclination angle of the acceleration plate 509 is adjusted by the extension and retraction of the electric telescopic rod 507;

[0026] 3) Then, an external gas source is introduced, and the gas is blown toward the material under the guidance of the acceleration plate 509;

[0027] 4) Finally, due to the different air blowing intensities on both sides of the acceleration plate 509, the material is accelerated and discharged from the discharge port 506.

[0028] In summary, the rotary valve uses a transverse acceleration chamber, and a working mechanism 5 is arranged inside the valve body 2. The device uses an electric telescopic rod 507 to adjust the inclination angle of the acceleration plate 509, and an external source is introduced at the air inlet 505. The air pressure and flow rate on both sides of the acceleration plate 509 can be adjusted, and the gas inside the acceleration chamber 504 is guided at the same time, thereby achieving the effect of accelerating the conveying, which can make the material conveying smoother and the conveying volume larger, and solves the problem that the existing rotary valve has limited material conveying, and when there is too much material, it is easy to cause blockage in the rotary valve and low conveying efficiency.
