Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with accompanying drawing embodiment:

[0017] Such as figure 2 The shown sanding dust screening device includes a dust screw conveyor 1 and a dust conveying fan 5, and a dust breaking device is installed at the outlet of the dust screw conveyor 1, and the breaking device includes two breaking rollers 11. The two breaking rollers 11 are connected to the power machine 10 through a belt transmission mechanism, and the power machine 10 in this embodiment is a motor. The discharge port of the dust screw conveyor 1 is connected with a screening bellows 2 , and the screening bellows 2 is connected with a dust conveying fan 5 through a pipe 4 . The bottom of the screening wind box 2 is provided with a first screened object outlet 7 , and an air inlet and an air inlet adjusting plate 8 are arranged above the first screened object outlet 7 . The screening bellows 2 is equipped with two diversion ad...

Abstract

The invention discloses a sanding dust screening device, and relates to the technical field of board processing. The device comprises a spiral dust conveyor and a dust conveying fan, wherein a screening air box is connected to a discharging port of the spiral dust conveyor; the screening air box is connected to the dust conveying fan through a pipeline; a first screening object outlet is formed inthe bottom part of the screening air box; an air inlet is formed in the upper part of the first screening object outlet, and an air inlet adjusting plate is mounted; a dust scattering device is mounted at the discharging port of the spiral dust conveyor; a plurality of flow guide adjusting plates which are vertically arranged at intervals are mounted in the screening air box; and a plurality of second screening object outlets are formed in the lower parts of the flow guide adjusting plates. Compared with the prior art, the device has the advantages that sanding dust is scattered into dispersed dust through the scattering device and is screened by layers through the plurality of flow guide adjusting plates; sand and large dust particles are screened out; the screening effect is good; the recovered sanding dust basically does not contain sand; and when a rough board is subjected to sanding, the surface is prevented from sand marks.

Description

technical field [0001] The invention relates to the technical field of plate processing, in particular to a sanding dust screening device. Background technique [0002] During the production process of medium density fiberboard, it is necessary to carry out surface sanding treatment on the hot-pressed wool board, which will generate a large amount of sanding dust. In order to save energy, reduce consumption, and effectively utilize resources, sanding dust is screened and reused. Currently used sanding dust screening devices such as figure 1 As shown, it includes a dust screw conveyor 101 and a dust conveying fan 104. The discharge port of the dust screw conveyor 101 is connected with a screening bellows 102, and the screening bellows 102 is connected with the dust conveying fan 104 through a pipeline 103. At the bottom of the screening bellows 102, there is a The screened object outlet 105 is provided with an air inlet and an air inlet regulating plate 106 above the screen...
