detailed description

Referring to accompanying drawings 1 to 3, the utility model is composed of a housing 2 arranged on a support 4 and a filter chain net 8 which is provided with circulating operation. The housing 2 is provided with a filter chain net 8, a filter cotton 11 and a support grille16.

The housing 2 adopts a box with an upper air inlet 1 and a side air outlet 3 structure, a support grid 16 is provided in the middle of the box, and a filter cotton inlet 21 and a filter cotton outlet 22 are respectively arranged on the housing 2 on both sides; The support grid 16 is provided with a circulating filter chain net 8, and the filter cotton 11 is arranged on the filter chain net 8 on the support grid 16 that enters the housing 2 through the filter cotton inlet 21, and the filter cotton 11 is filtered and saturated by The filter chain net 8 takes it out of the housing 2 from the filter cotton outlet 22; the filter chain net 8 is an endless mesh belt arranged on some chain net bearings 7, and the chain net bearings 7 are arranged on the support 4 and are connected by the chain 9 Connected with the motor 10, the motor 10 drives the filter chain net 8 arranged on the chain net bearing 7 to circulate; the filter cotton 11 is a cotton roll and is arranged on the support 4 on the side of the filter layer inlet 21 by a supporting roller; The housing 2 is provided with a differential pressure gauge 17 connected to the controller 6, and the two pressure measuring ports of the differential pressure gauge 17 are respectively arranged on the inner wall of the housing 2 above and below the support grid 16; the motor 10 is connected to control 6 and the controller 6 drives the circular operation of the filter chain net 8 according to the set pressure difference value, drives the translation of the filter cotton 11, and realizes the automatic replacement of the filter cotton 11. The filter cotton inlet 21 and the filter cotton outlet 22 are respectively provided with a bead 12 and a pressure roller 13 for adjusting the degree of fit between the filter cotton 11 entering and exiting the housing 2 and the filter chain net 8; The observation window 14 and the inspection opening 15 are arranged on the housing 2 corresponding to the side air outlet 3 , and the observation window 14 is arranged on the housing 2 above the support grille 16 .

The utility model works like this: the waste body containing paint dust and viscous matter enters the casing 2 from the upper air inlet 1, and enters the lower casing after being filtered by the filter cotton 11, and is discharged from the side air outlet 3, and the filter cotton 11 is rolled The thickness of the cylinder is 5-50mm, and the wind speed of the filter section is controlled at 0.8-2.0m/s. When the exhaust gas passes through the filter cotton 11, paint dust or viscous substances are trapped on the filter cotton 11. When the air passes through the filter cotton 11, the resistance will increase, that is, the pressure difference between the upper and lower shells of the filter cotton 11 will increase. When the pressure difference reaches the set upper limit, the filter cotton 11 is close to saturation and has lost its filtering ability. At this time, the filter cotton 11 needs to be replaced . The upper limit of the pressure difference can be set through the differential pressure meter 17, and the upper limit is generally set at 200-400Pa. The pressure difference between the upper and lower casings 2 of the filter cotton 11 is monitored through the differential pressure gauge. When the differential pressure gauge reaches the set After the value is set, the start signal will be fed back to the controller 6 to drive the motor 10.
