Mist paint collecting device

Abstract

The invention provides a mist paint collecting device. The mist paint collecting device comprises a conical centrifugal shell, a cuboid-shaped condensing box, a water tank with a water supplementing pipe and a recovering tank, a rotating shaft is rotatably connected in the centrifugal shell, a conical spiral blade is fixed to the rotating shaft, a gas inlet pipe is connected to the upper end of the centrifugal shell, the lower end of the centrifugal shell is connected with the recovering tank through a liquid collecting pipe, a horizontal partitioning plate is arranged in the condensing box and divides the condensing box into a condensing cavity and a liquid accumulating cavity, the condensing cavity and the liquid collecting pipe are communicated with through a side gas discharging pipe,the liquid accumulating cavity is communicated with the recovering tank through a liquid return pipe, a lower condensing baffle plate is vertically arranged on the partitioning plate, an upper condensing baffle plate is fixed to the top wall in the condensing cavity, a tail gas pipe communicated with the condensing cavity is arranged on the side face of the condensing box, and the tail gas pipe and the side gas discharging pipe are located on the two side faces of the condensing box respectively. The mist paint collecting device captures paint in paint mist through a centrifugal method and a condensing method, the collection rate is high, the size of the device is small, and floor space is small.

Description

technical field [0001] The invention belongs to the technical field of paint mist treatment and relates to a paint mist collection device. Background technique [0002] Paint is a toxic chemical substance. During the spraying process, a large part of the paint mist cannot be attached to the workpiece, and this part of the paint is mixed in the air in the spraying room in the form of mist, and is directly discharged into the air. It is very harmful to the body and pollutes the environment very much. [0003] Paint mist treatment methods are usually divided into two types: dry treatment method and wet treatment method. The dry treatment method is to use dry materials (filters, etc.) to capture the overspray paint mist. Working principle: The glass fiber or paper fiber is made into a filter and fixed on the frame of the filter. Under the action of the fan, the paint mist enters the filter and is adhered. The air that removes the paint mist is discharged to the outside of the ...

AI Technical Summary

Problems solved by technology

[0005] Disadvantages of the dry treatment method: the filter material needs to be replaced frequently. Since the paint holding capacity of the dry filter material is less than that of liquid water (adding coagulant), when the dry treatment method is used, the filter material needs to be replaced frequently, and secondary Pollution (paint mist filter cotton needs secondary treatment)

The paint mist is not completely filtered, the equipment is seriously polluted, the danger of fire is high, and there are potential safety hazards

[0006] Disadvantages of the wet treatment method: the foundation is complex and the cost is high; a complete circulating water system is required, there will be sewage, and the sewage needs to be treated; the overspray paint mist falling into the pool is easy to stick to the pool wall, water pipes, and the inner shell of the pump , more difficult to clean; the required fan pressure is higher, which increases the consumption of paint
