It is stirred and mixed by the manufacturer. It can be widely used in densely populated residential areas, public buildings, large public places, flammable and explosive places, and places with strict fire protection requirements. It can also be used as a fire isolation zone to improve the fire protection standards of buildings. The raw materials required for mortar preparation are usually stored in silos.

[0003] At present, the existing silo usually includes a storage tank body, a motor is fixed on the upper end of the storage tank body, an agitator is fixed on the output end of the motor, and a regulating valve is installed at the outlet end of the storage tank body.

[0004] In the above scheme, the prior art controls the output and flow rate of materials by controlling the opening and closing of the regulating valve, but the regulating valve is prone to wear and tear during long-term operation, causing damage, resulting in leakage of materials in the silo. When the regulating valve needs to be replaced, the material in the silo needs to be drained out before replacement, resulting in low practicality. Utility Model Content

The rotation of the stirring shaft drives the stirring paddle and the stirring blade to rotate, so that the material in the silo can be effectively stirred, thereby preventing the material from piling up and sticking.

[0016] The utility model is further configured as follows: the fixing assembly includes a connecting plate fixed to the side wall of the first butterfly valve, an arc groove is formed on the side wall of the connecting plate, a bolt is threaded on the side wall of the wrench, the bolt passes through the protruding end of the wrench and is inserted into the arc groove, and a nut is threaded on one end of the bolt inserted into the arc groove.

[0017] Through the above technical solution, when the wrench needs to be fixed, the wrench can be effectively fixed through the cooperation of the bolt and the nut.

[0018] The utility model is further configured as follows: two arc-shaped clamping plates are fixed on the side walls of the connecting plate, and the two arc-shaped clamping plates are respectively located at the upper and lower ends of the nut.

[0019] With the above technical solution, when the wrench is fixed at a desired position by means of bolts and nuts, it is usually necessary to fix the bolts or nuts, and then turn the bolts or nuts to fix the wrench at the desired position, which causes inconvenience in operation. By providing an arc-shaped clamping plate, the nut cannot be freely rotated, so that the wrench can be fixed at the desired position by only turning the bolts.
