Safety device for cyclone discharge system

Abstract

The invention discloses a safety device for a cyclone discharge system. The safety device comprises a valve body which is connected with a discharge hole of a cyclone collector, wherein two turnover boards are arranged up and down in the valve body; the turnover boards are arranged on a rotating shaft which is transversely arranged in the valve body horizontally; turnover torque is formed between the rotating shaft and the gravity centers of the turnover boards; one end of the rotating shaft extends out of the valve body and is connected with a balancing weight; anti-turnover torque is formed between the gravity center of the balancing weight and the rotating shaft, and is in balance with the turnover torque; the turnover boards are transversely arranged in a channel closing the valve body horizontally. The safety device is of a flap valve structure without electric control, and automatically acts by virtue of the mechanical gravity, so that an equipment fault of a flour mill unit in the production process is greatly reduced, power consumption of the system in the normal operation process is lowered, the utilization rate of equipment is increased, thus the production efficiency is effectively increased.

Description

(1) Technical field: [0001] The invention relates to a powder conveying device, in particular to a safety device for a cyclone discharging system. (two) background technology: [0002] Rubber powder is the abbreviation of rubber powder, which is generally processed from waste rubber such as waste tires. Products are widely used in sports plastic sports fields, playgrounds, rubber floor tiles, waterproof membranes, waterproof coatings, road modified asphalt, rubber products and other fields. [0003] The production of the rubber powder uses a waste rubber mill, and the original feeding and returning of the mill are done manually, which requires a large number of personnel and high labor intensity; later, the feeding and discharging of some equipment adopt The screw, silo, shut-off valve and screening system cycle to complete this production process, but in the production process, it is very easy for the fiber in the waste rubber to block the shut-off valve, thereby burning t...
