Accurately controlled explosion-proof type automatic feeding device

Abstract

The invention provides an accurately controlled explosion-proof type automatic feeding device. The accurately controlled explosion-proof type automatic feeding device comprises a platform bracket, a feeding container, a negative-pressure feeding mechanism and a spiral discharging mechanism, wherein the feeding container is arranged on the platform bracket, is used for containing a material, and reminds the position of the material through an upper limit sensor and a lower limit sensor, arranged on the inner wall; the negative-pressure feeding mechanism comprises an explosion-proof fan, a hand-held feeding pipe, a feeding hose, a feeding opening and a discharging opening, and is used for automatically sucking the material and storing the material in the feeding container; and the spiral discharging mechanism is arranged on the lower side of the feeding container, and is used for the spiral even and controllable discharging of the material and the accurately control of the weight of fed material. The accurately controlled explosion-proof type automatic feeding device has the advantages that the weight of the fed material can be accurately controlled according to user requirements, material feeding is more even and controllable due to the adoption of automatic spiral discharging, dust stirred in the discharging process can be recycled, dust pollution is reduced, and the device has explosion-proof property and is simple and safe to use.

Description

technical field [0001] The invention belongs to the field of automatic feeding devices, in particular to a precisely controlled explosion-proof automatic feeding device. Background technique [0002] The automatic feeding device can simulate manual feeding and put the powdery material into the designated reaction kettle. The traditional automatic feeding machine is difficult to accurately control the weight of the feeding material, and there are problems such as large powder dust and unevenness during feeding. Moreover, the feeding machine operates for a long time, and the motor is prone to overheating and stopping, and even an explosion may occur in serious cases. SUMMARY OF THE INVENTION [0003] In view of this, the present invention aims to propose a precisely controlled explosion-proof automatic feeding device, which can precisely control the weight of the feeding material according to the needs of the user, automate the spiral feeding, the feeding is more uniform and...
