Dust separation device of straw bulking machine

Abstract

A dust separation device of a straw bulking machine comprises a sealing cover, an eddy fan disposed on one side of the sealing cover and a main conduit disposed on the other side, wherein a driving machine is disposed on an input end of the eddy fan. The technical keys are characterized in that a filtering screen is disposed between the main conduit and the sealing cover, filtering cloth is disposed on the tail end of the main conduit, an auxiliary conduit is disposed on the main conduit, a pressure relief assembly is disposed in the auxiliary conduit, and exhaust holes in the tail ends of the main conduit and the dust auxiliary conduit communicate into a liquid filtering container; the pressure relief assembly comprises an overflow valve, a pressure relay and a pressure sensor; and a driving circuit used to control the output power of a motor is disposed on the driving machine, and a negative feedback circuit is established between the pressure relief assembly and the driving circuit. Fundamentally, the problems that a lot of dust is generated during work of the straw bulking machine and working environments are polluted are solved; and the device has the advantages that a feeding hole is sealed; dust is separated rapidly; the pressure of the filtering device is steady; breaking natures of straws are not influenced; key components can be replaced easily, etc.

Description

technical field [0001] The invention relates to the field of straw puffing equipment, in particular to a dust separation device for a straw puffing machine, which is mainly suitable for collecting and processing dust at the material inlet of the puffing machine. Background technique [0002] At present, the dust generated during the use of the straw puffing machine has not been treated, and it is directly diffused into the atmosphere, seriously affecting the working environment. During the use of the straw puffing machine, a lot of dust will be generated due to high-speed rotation, high temperature and high pressure, and impurities in the raw materials. The feeding port of the traditional straw puffing machine is in a semi-open state, and a large amount of dust is generated during the straw entering process and directly diffuses in the air, which seriously affects the indoor environment. [0003] The existing extruder dust separation device, such as the utility model patent...
