Abstract

The invention relates to a quantitative interrupted dust adding device. The quantitative interrupted dust adding device comprises a taper hopper, a box, a double-head piston cylinder and a dust blowing pipe; a feed hole in the upper end of the dust blowing pipe is connected with the bottom of the box; the upper end of the double-head piston cylinder is arranged inside the box; the lower end of the double-head piston cylinder penetrates the bottom of the box to be arranged inside the feed hole of the blowing pipe; a discharge hole of the tapper hopper is connected with the upper end opening of the double-head piston cylinder; the double-head piston cylinder comprises a cylinder body, an upper piston head, a lower piston head and a screw rod; the upper end opening of the cylinder body is connected with the discharge hole of the tapper hopper; the lower end opening of the cylinder body penetrates the bottom of the box body to be arranged inside the feed hole of the dust blowing pipe; distance between the upper piston head and the lower piston head is not larger than that between the upper end opening and the lower end opening of the cylinder body. The quantitative interrupted dust adding device has the advantages of being small in average dust adding speed, high in accuracy, simple in structure and high in stability.

Description

technical field

[0001] The invention relates to a dust adding device, in particular to a quantitative intermittent dust adding device. Background technique

[0002] At present, most of the quantitative dusting devices are continuous, and the speed of dusting is mostly several kilograms / hour / to several tons / hour. Its dusting is more common in the structure of belt type and spiral type. A belt-type automatic quantitative feeder, including a feeding hopper, a conveying control metering device, a dust collection box, and a cleaning device. The conveyor belt is supported by large and small rollers. A metering section is provided on one side of the conveying control metering device. The metering section is composed of a metering roller placed under the belt and connected to a pressure sensor. The existing structure is complex, resulting in poor stability. Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide a quantitativ...
