Description

Powder vacuum metering tank Technical Field The utility model relates to the technical field of feeding tanks, in particular to a powder vacuum metering tank. Background Powder negative pressure conveying and feeding are needed in a plurality of industries such as rubber and plastic, pharmacy, food, chemical industry and the like, and a powder vacuum feeding hopper and a feeding bin with vertical stirring and high and low material levels are needed in the conventional situation to finish powder feeding, storage and discharging. However, in many cases, due to space limitation on site and special technological process, customers can require that the powder vacuum feeding hopper and the supplementing bin are integrated, so that the powder vacuum metering tank is designed, and the weighing sensor is used for replacing the function of the level gauge, but under the condition, vertical stirring cannot be used, and due to the characteristic that powder is easy to bridge, the powder is blocked at the discharging opening, and the discharging cannot be smoothly performed. In order to enable powder to be smoothly discharged, the pneumatic vibrator is arranged on the outer wall of a cone section bin of a discharging hole of an existing powder vacuum metering tank, and the problem of blocking of part of powder can be solved, but due to the characteristics of part of the powder, the effect of the vibrator is not obvious, and the vibrator plays a role in reaction, so that the powder is more vibrated and more solid, and the blocking is more serious. Therefore, aiming at the existing powder vacuum metering tank, the problem to be studied is solved by improving the vacuum metering tank to solve the problem of blockage of the cone section bin of the discharging hole. Disclosure of utility model The problem to be solved is to improve current powder vacuum metering jar in order to solve the problem of blowing out mouth cone section storehouse putty.
