Particle material rotary valve

Abstract

The invention discloses a particle material rotary valve. The particle material rotary valve comprises a valve body, a rotor, a driving mechanism, a controller and a junction box, wherein the upper port of the valve body is a feeding port and the lower port of the valve body is a discharge port, each of a left port and a right port of the valve body is provided with an end plate, and a shaft holeis formed in the middle of each end plate; a plurality of material cutting teeth are arranged on one side of the inner wall of the feeding port side of the valve body in a protruding mode, an exhaustport is formed in the other side of the valve body, exhaust grooves are formed in the bottom surfaces of the material cutting teeth, and an exhaust channel connected to the exhaust port and the exhaust grooves is formed in the upper part of the inner wall of the valve body; the inner wall, on the same side of the exhaust port, of the discharge port of the valve body is provided with the material cutting teeth in the protruding mode; the rotor is in a star-shaped structure, and comprises a central shaft and a plurality of blades thereon; the driving mechanism comprises a motor, a speed reducer,a driving chain wheel, a driven chain wheel and a chain, a chain wheel protecting cover and a sensor, wherein the motor and the speed reducer are arranged on one side of the valve body, the driving chain wheel is arranged on a speed reducer output end and the driven chain wheel is arranged on the end part of one end of the rotor central shaft, the chain wheel protecting cover is arranged outsidethe driving chain wheel and the driven chain wheel in a covering mode, and the sensor is arranged on the outer side of the other end of the rotor center shaft; and the controller and the junction boxare arranged on the other side of the valve body, and the motor and the sensor are electrically connected to the interior of the junction box.

Description

technical field [0001] The invention relates to a granular material rotary valve. Background technique [0002] Granular material rotary valves are mostly used in pneumatic conveying systems in many industries such as petroleum, chemical industry, medicine, grain, food, building materials, etc. During the production process, it may be difficult to obtain continuous and stable work or shut down due to granular materials in the production process. Contents of the invention [0003] The object of the present invention is to provide a granular material rotary valve. During the use of the rotary valve, individual particles are cut off under the combined action of the rotor and the cutting teeth at the inlet, and the pressurized gas conveying the material passes through the exhaust groove of the valve body. Connected, so that excess gas is discharged from the valve body through the exhaust port of the valve body, so that the material can flow continuously and evenly or in the cl...
