The crushing valve is a new type of valve developed for crushing a large amount of materials in the cement silo in the actual production process of the cement plant. It is installed at the bottom of the cement silo together with the unloader. When a large amount of material in the warehouse flows through the unloader, it is easy to cause the valve to be blocked, but there is currently no suitable solution for the valve. In view of the problems existing in the prior art, technicians provide a crushing valve with a function of feeding and discharging materials, which can easily and uniformly damage the materials in the pipeline and easily prevent the materials from clogging.

In order to solve the above problems, the crushing valve adopts the following technical scheme: a crushing valve with charging and discharging function, including a shell, the two ends of the shell are respectively connected with a sealing box and a fixing box, and a sealing box and a fixing box are connected between the sealing box and the fixing box. The rotating shaft and the fixed shaft are provided with a pair of through holes matched with the rotating shaft and the fixed shaft on the shell, and the motor matched with the rotating shaft is fixedly connected to the outer wall of the sealing box. The power output end of the motor passes through the sealing box and is fixedly connected with the rotating shaft. The rotating shaft is connected with a plurality of evenly distributed and matched pulverizing blades; the inner wall of the casing is fixedly connected with a plurality of evenly distributed and matched with the pulverizing blades. The side wall of the casing is fixedly connected with an air inlet; the air passage matching the air inlet is excavated in the casing; the inner wall of the casing is connected with a plurality of nozzles that are evenly distributed and communicated with the air passage, and the casing and the sealing box are provided with There are multiple sealing rings, which are matched with the rotating shaft and the fixed shaft, which is convenient for the fixing of the rotating shaft and the fixed shaft, and the rotating shaft and the fixed shaft are not easy to dislocate. Bearings matched with the through holes are connected between the two ends of the rotating shaft and the casing, so that the rotating shaft is convenient to rotate. The service door is attached to a hinge on the side wall of the enclosure, allowing technicians to service parts inside the enclosure. Two pairs of fixing screws are connected between the sealing box and the fixing box and the shell, which is convenient for disassembly and assembly of the sealing box and the fixing box.

Compared with the prior art, the advantages of the crushing valve are as follows: 1. The solution is convenient to uniformly destroy the materials in the pipeline, and is easy to prevent the materials from being blocked. 2. There are multiple sealing rings in the housing and the sealing box. One pair of sealing rings is fixedly connected with the fixed shaft, and the other pair of sealing rings is sleeved on the rotating shaft, which is convenient for fixing the rotating shaft and the fixed shaft, so that the rotating shaft and the fixed shaft are not easily dislocated. 3. Bearings matching the through holes are connected between the two ends of the rotating shaft and the casing, which is convenient for the rotating shaft to rotate. 4. The hinge on the side wall of the shell is connected with a maintenance door, which is convenient for technicians to check the parts in the shell. 5. Two pairs of fixing screws are connected between the sealing box and the fixing box and the shell, which is convenient for the disassembly and assembly of the sealing box and the fixing box.
