Aggregation dust collecting device for waste plastic film of dry decontamination machine

Abstract

The invention discloses an aggregation dust collecting device for a waste plastic film of a dry decontamination machine, which comprises a machine frame, a hopper, a casing, a motor, a motor transmission, a transmission device, brush rods, a transmission turning device, arc-shaped porous baffle plates, a screw rod, a charging barrel, a feed opening, a discharge opening and a suction opening. The aggregation dust collecting device adopts the principle that when equipment is opened, the motor drives the transmission device to drive the brush rods and the screw rod to rotate, when the waste plastic film after dry cleaning enters the casing, along with continuous rotating and squeezing of the screw rod, under the action of negative pressure in the casing, residual dust is discharged into a cavity II through the arc-shaped porous baffle plates, and then enters a cloth bag dust removing device through the suction opening, the squeezed waste plastic film in the cavity of the charging barrel is squeezed and pushed out from the discharge opening and collected, and the brush rods continuously rotate, so as to prevent blocking in the porous positions of the arc-shaped porous baffle plates by the waste plastic film due to action of negative pressure. The aggregation dust collecting device can collect cleaned waste plastic films conveniently and in a centralized manner, so as to effectively remove residual dust, improve the cleaning rate, reduce environment pollution, and improve recycling quality of the waste plastic films.

Description

technical field [0001] The invention relates to a machine for collecting waste plastic film after dry cleaning and the residual dust in the waste plastic film, and more specifically refers to an aggregate of a waste plastic film dry decontamination machine that can effectively improve the cleaning rate and reduce environmental pollution Dust collection device. Background technique [0002] I once invented the plastic dry decontamination machine involved in the recycling of agricultural plastic film, patent number: 200610078012. In the actual use of this patented equipment, the cleaning rate of waste plastic film is about 95%, and the remaining 5% of dust is It will be discharged out of the machine together with the washed waste plastic film through the discharge port of the dry decontamination machine. Because the waste plastic film is discharged in a spray shape (formed by the centrifugal force of high-speed rotation in the machine), the remaining 5% dust will be As the wa...

[0002] I once invented the plastic dry decontamination machine involved in the recycling of agricultural plastic film, patent number: 200610078012. In the actual use of this patented equipment, the cleaning rate of waste plastic film is about 95%, and the remaining 5% of dust is It will be discharged out of the machine together with the washed waste plastic film through the discharge port of the dry decontamination machine. Because the waste plastic film is discharged in a spray shape (formed by the centrifugal force of high-speed rotation in the machine), the remaining 5% dust will be With the separation and diffusion of waste plastic film at the discharge port, the production environment will be polluted, which is not conducive to the health of production staff

Secondly, the remaining dust is mixed in the waste plastic film, which reduces the cleaning rate of the dry decontamination machine

Thirdly, due to the physical properties of waste plastic film, the waste plastic film ejected at high speed is not convenient for direct centralized collection
