Description

Anti-shredging rotary feed valve

The present invention relates to a rotary feed valve, and more particularly to a shredder rotary feed valve.

As one of the key equipments in the pneumatic conveying system, the rotary feeding valve plays the role of conveying materials into the conveying system. It can ensure the smooth and quantitative entry and exit of the materials, and maintain the pressure difference between the conveying system and the outside world. It is widely used in industries such as plastics, textiles, food processing, energy and power, machinery and building materials, and import terminals. Rotary feed valves are divided into different types depending on the nature of the material being conveyed. When conveying the granular material, the pellets on the rotary feed valve dial plate used in the prior art will move to both sides when the rotor vane rotates, and even if the elongated guide groove is provided, the pellets will be squeezed. It is not easy to fall on both sides, so the pellets may be crushed and broken. At the same time, it will cause the valve body to vibrate, thus affecting the service life of the supply valve.

The technical problem to be solved by the present invention is that, in view of the deficiencies of the prior art, a shark feed rotary supply valve capable of effectively preventing the pellets from being crushed and crushed is provided.

The technical solution adopted by this creation to solve its technical problems lies in: the anti-shredging rotary supply valve provided by the creation, comprising: a valve body and a rotor, The valve body comprises a feed opening, a discharge opening and a hollow chamber, the hollow chamber is open laterally on both sides, and the hollow chamber is in communication with the inlet opening and the discharge opening; the rotor is laterally mounted at In the hollow chamber of the valve body, the rotor includes a rotating shaft and a plurality of vanes, and the rotating shaft extends out of the valve body through openings on both sides of the hollow chamber, and the plurality of vanes are radially distributed on the rotating shaft The outermost end of the vane is a pointed material; wherein a wedge-shaped guide groove is formed on a side wall of the inner portion of the cavity in the valve body near the inlet, the outer circumference of the wedge-shaped guide is narrow and wide, and The upper part is narrower and wider at the upper part.

In another preferred embodiment, there are two wedge-shaped guide grooves respectively located on the side walls of the valve body in the interior of the chamber interior.

In another preferred embodiment, the side wall of the valve body is further provided with air holes communicating with the hollow chamber.

In another preferred embodiment, the inlet of the valve body is provided with a feed port flange, and the discharge port of the valve body is provided with a discharge port flange.

In another preferred embodiment, the material of the shatterproof rotary supply valve is selected from stainless steel, carbon steel or other wear resistant materials.

The anti-shredging rotary feed valve of the present invention has the following beneficial effects:

1. Since the inner side wall of the cavity in the valve body is provided with a narrow inner width, a narrow and narrow wedge-shaped guide groove, the pellet can easily enter the guide groove and fall, and no pellets are generated. The case where the guide groove is crushed and broken.

2. Since no pellets are crushed and crushed, the entire rotary feed valve is not easy to generate large vibration during operation, so the noise generated during operation is reduced.

3. The use of the entire rotary feed valve due to excessive squeezing and vibration Life expectancy has been extended.

In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the embodiments and the accompanying drawings: Referring to FIG. 1 to FIG. 5, it is disclosed that a shatterproof rotary supply valve is disclosed. The anti-shredging rotary feed valve mainly comprises a valve body 1 and a rotor 2.

The valve body 1 mainly comprises a feed port 11, a discharge port 12 and a hollow chamber 13, the hollow chamber 13 is open laterally on both sides, and the hollow chamber 13 and the inlet port 11 and the discharge port 12 phases are connected.

The rotor 2 is laterally mounted in the hollow chamber 13 of the valve body 1, and the rotor 2 mainly includes a rotating shaft 21 and a plurality of vanes 22. The rotating shaft 21 extends out of the valve body 1 through the lateral opening of the hollow chamber 13, and the vanes 22 are radially distributed on the rotating shaft 21, and the outermost end of the vane 22 is a pointed baffle 23. A wedge-shaped guide groove 14 is formed in the side wall of the inside of the cavity 13 in the valve body 1 near the inlet port 11, and the wedge-shaped guide groove 14 has a narrow inner width and a narrow upper portion. There are two wedge-shaped guide grooves 14 which are respectively located on the side walls of the valve body 1 on both sides of the inside of the cavity chamber 13. An air hole 15 communicating with the hollow chamber 13 is further disposed on the side wall of the valve body 1.

In addition, a feed port flange 16 is disposed at the inlet port 11 of the valve body 1, and a discharge port flange 17 is disposed at the discharge port 12 of the valve body 1. The material of the anti-shredging rotary feed valve is selected from stainless steel, carbon steel or other wear-resistant materials.

The creation of the anti-shred material rotary feed valve when working by the drive The rotor 2 is driven to rotate around the rotating shaft 21 in the cavity 13 inside the valve body 1, and the material enters from the inlet port 11 and falls between the vanes 22 of the rotor 2, and is brought out as the rotation of the vane 22 is carried out. The spout 12 is output outside the valve body 1. Since the pellets on the pointed baffle 23 are moved to both sides when the vane 22 is rotated during the conveyance of the granular material, after the wedge-shaped guide groove 14 is provided on the side wall of the inside of the cavity 13 in the valve body 1, The pellets are not squeezed between the vanes 22 and the side walls. And since the outer circumference of the wedge-shaped guide groove 14 is narrow and the upper portion is narrow and wide, the pellets can smoothly enter the wedge-shaped guide groove 14 and fall from the wedge-shaped guide groove 14 into the hollow chamber 13 without being crushed in the wedge shape. Inside the guide groove 14. At the same time, the entire rotary feed valve is not easy to generate large vibration during operation, so the noise generated during operation is reduced, and the service life of the entire rotary feed valve is also prolonged.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present creation. Any modifications, equivalent replacements, improvements, etc., which are made within the spirit and principles of the present creation, should be included in the present creation. Within the scope of protection.
