Abstract

The utility model discloses a water curtain cabinet for efficiently removing paint mist, which is used for collecting and treating spraying waste gas. Traditional cascade cabinet relies on the spraying air current to strike the cascade board and gets rid of the coating cloud granule in the gas, and is unsatisfactory to the coating cloud gets rid of the effect in the spraying air current, has most coating cloud can be along with the air current exhaust cascade cabinet of airing exhaust. The utility model designs and adds a multi-functional paint mist removing structure such as a baffling impeller, a baffling grid, a filter and the like on the basis of the traditional water curtain cabinet structure, in particular to the baffling impeller which is driven by an impeller motor to rotate. Wherein the baffle impeller is positioned in the air flow passage below the water curtain plate. By the aid of the water curtain cabinet, most paint mist in collected spraying waste gas can be removed by the aid of the air flow through colliding a liquid film on the baffling impeller blades when the collected spraying waste gas passes through the channel below the water curtain in the spraying operation process. The baffle grid removes water mist from the exhaust gas and further removes paint mist. The filter can deeply remove paint mist in the waste gas.

Description

High-efficient cascade cabinet of getting rid of coating cloud

Technical Field

The utility model relates to the technical field of environmental protection, in particular to spraying waste gas collecting and treating equipment.

Background

The water curtain cabinet is a novel environment-friendly device which is simple in operation, stable in use and safe, is mainly applied to paint spraying assembly line workshops of various industries and serves as environment-friendly equipment for collecting and treating paint spraying waste gas. The water curtain cabinet can directly spray redundant paint mist in a water pool or on a water curtain surface during paint spraying, and odor generated during paint spraying and a small amount of unadsorbed paint powder are filtered by the multiple layers of water curtain walls and then discharged outside a workshop through the exhaust fan, so that the effects of purifying the paint spraying working environment and protecting the personal health are achieved.

Traditional cascade cabinet structure usually collects the gas passage in cascade board below design, and the water curtain board leads the trickle and flows down from this passageway cross-section, gets into the water tank, does not possess the coating cloud ability of holding back when the air current passes through. The water curtain cabinet discharges paint mist in the waste gas, and subsequent waste gas purification equipment is required to carry out filtration treatment. Improper process design can cause paint mist to enter a fan and purification equipment, and operation abnormity and faults are caused; the discharge of a large amount of paint mist causes great holding pressure on a filter device, and the filter material replacement cost is high; further, the subsequent purification equipment blocked by the paint mist can also cause adverse effects on the production and exhaust. The ability is got rid of to the body coating cloud of cascade cabinet directly influences terminal exhaust-gas treatment equipment's operating stability and safety, further also influences the stability and the product quality of spraying production.

Disclosure of Invention

Detailed Description

Example 1

Fig. 1 includes the cabinet body (1) of the water curtain cabinet, the water tank (2), the water replenishing tank (3), the water pump (4), the sedimentation channel (5), the overflow launder (6), the water curtain plate (7), the air exit (8) structure, its characteristic lies in, the said water curtain cabinet also includes the baffling impeller (9) and the impeller motor (10), the baffling bar (11), the filter (12). Wherein the baffle impeller (9) is positioned in the air flow channel below the water curtain plate (7).

The blades of the baffling impeller (9) are in a wedge-shaped corrugated structure in the embodiment.

The water curtain cabinet of the exemplary embodiment of the application works as follows:

the spraying operation is performed on the water curtain plate (7) during production. The water pump (4) extracts water from the water replenishing tank (3) and enters the overflow groove (6), and the water overflowing from the overflow groove (6) uniformly flows down from the water curtain plate (7) to form a flowing water film. When in paint spraying, part of paint mist sprayed out of the spray gun is attached to a workpiece, most of the rest of the paint mist rushes to the water curtain plate (7), is captured by a flowing water film on the plate wall and enters the water tank (2) at the bottom of the water curtain cabinet together, and paint particles are deposited at the bottom of the water tank (2). The water tank (2) and the water replenishing tank (3) are of an upper communicated structure, and clean water without paint slag on the upper layer of the water tank (2) overflows into the water replenishing tank (3).

The paint mist floating in the paint spraying operation space of the water curtain cabinet firstly passes through the baffling impeller (9) along with the ventilation air flow of the water curtain cabinet. The impeller rotates continuously, a water film is taken out from the water tank (2), the air flow passes through the middle of the blade layer of the impeller and is continuously changed in flow direction by the corrugated structure of the blade, paint mist particles impact the water film on the blade by means of inertia when the air flow changes direction, and then the paint mist particles are captured by the water film and enter the water tank (2) along with the rotation of the impeller for deposition.

Most paint mist particles are removed by the airflow after passing through the deflection impeller (9), then the airflow enters the deflection grating (11) through the sedimentation channel (5) to remove small liquid droplets, and the surface liquid film of the deflection grating (11) can further remove the paint mist particles in the airflow. The condensed water with paint mist of the deflecting grid (11) flows back to the water tank (2) along the wall of the sedimentation channel (5).

The air flow treated by the deflection impeller (9) and the deflection grid (11) passes through a primary filter (12), and the filter (12) can filter out particles and liquid drops with the particle size of 5 microns or more. The air flow after the deep filtration basically reaches a state without particles, is discharged from an air outlet (8) of the water curtain cabinet and enters subsequent waste gas treatment equipment.

The water curtain cabinet is used according to the working process, paint slag deposited in the water tank (2) is periodically removed, and the disassembly and washing baffling impeller (9), the baffling grid (11) and the filter (12) are periodically checked through the checking door (13).

While certain exemplary embodiments and examples have been described herein, other embodiments and modifications will be apparent from the above description. Various changes and modifications to the embodiments of the present application may be made by those skilled in the art without departing from the teachings of the present application. The inventive concept is therefore not limited to the embodiments but is to be defined by the appended claims along with their full scope of equivalents.
