no. 1 Embodiment approach ）

[0152] figure 1 , figure 2 Indicates a painting operation room in which a painting booth 2 for painting an object 1 (in this example, an automobile body) with a coating gun is formed, and in this painting booth 2 Equipped with a conveying device 3 for conveying the object 1 to be coated.

[0153] The painting room 2 is along the conveying direction of the object to be coated 1 ( figure 1 The tunnel-like indoor shape extending in the depth direction in ) and in this painting booth 2, the temperature-humidity-adjusted ventilation air SA is supplied from the ceiling portion 2a to the entire tunnel-shaped indoor room.

[0154] Below the painting chamber 2, there is formed an exhaust chamber 4 extending along the conveying direction of the object 1 like the painting chamber 2, and the exhaust chamber 4 receives the air blown to the painting chamber 2 by the air SA for ventilation. Exhaust air EA is supplied and discharged downward from the painting booth 2 through the grid floo...

no. 2 Embodiment approach ）

[0187] Figure 4 Shows a painting booth in which the painting booth of the first embodiment is improved. In this coating booth, the chamber width of the exhaust chamber 4 is made smaller than that of the painting chamber 2. 4, a recessed portion 17 is formed below the painting booth 2 on both lateral sides.

[0188] In addition, the filter devices 5 are arranged in a row in the longitudinal direction of the operating room in a state adjacent to the exhaust chamber 4 in these recessed portions 17 .

[0189] The slit-shaped inflow ports 10 of these filter devices 5 are the same as the painting operation room of the first embodiment, and are arranged along the length direction of the operation room in the same manner as the painting operation room of the first embodiment in the longitudinal direction of the operation room. They are formed in a row at the respective lower end portions of both side walls 4 a of the exhaust chamber 4 , and open into the exhaust chamber 4 at the bot...

no. 3 Embodiment approach ）

[0192] Figure 5Indicates a simple painting operation room, in which the coating gun 18 is located on the side wall of the coating room 2 for coating the object 1 to be coated. The side wall 2 c on the opposite side is used as a common form of the side wall of the device case 9 of the filter device 5 , so that the filter device 5 is adjacent to the painting booth 2 .

[0193] The inlet portion 10 of the slit-shaped filter device 5 extending in the width direction is formed at the lower end portion of the common side wall 2 c and opens to the bottom of the painting chamber 2 .

[0194] In the filter device 5, basically the same as the filter device shown in the first embodiment, the discharge air EA sucked into the device case 9 from the painting booth 2 through the slit-shaped inlet portion 10 is directed upward. The side changes direction and passes through the bag filter 8, and the paint mist in the exhaust air EA is collected by the bag filter 8.

Abstract

A filtering apparatus provides a uniformly distributed precoating agent (P) in a gas (EA) being processed and directed to a filter (8). To this end, the filtering apparatus (5) is provided with a flow inlet portion (10) which extends horizontally in the direction of width in a slit-like or rectangular shape. The flow inlet portion (10) has an upper rim portion in which a recessed retention portion (12) is formed to open downward when viewed in the longitudinal direction of the flow inlet portion (10). The recessed retention portion (12) is formed continuously in the longitudinal direction of the flow inlet portion (10). The flow inlet portion (10) is also provided, at a predetermined position in the longitudinal direction thereof, with a precoating agent nozzle (11), allowing the precoating agent (P) and a gas to issue through the precoating agent nozzle (11) in a jet toward the surface deep inside the recessed retention portion (12).

Description

technical field [0001] The present invention relates to a filter device, a painting booth using the filter device, and a simple painting booth using the filter device. [0002] In this filter device, a filter is built in the device case, and an inflow port for a gas to be processed containing adhering target substances such as paint mist and oil mist is provided in the device case. [0003] And, a precoating agent nozzle is arranged at the inflow port. The precoating agent nozzle sprays the powdery filter precoating agent together with the gas to the gas to be processed which has flowed into the device casing from the inflow port. Background technique [0004] In such a filter device, in order to reliably mix the precoating agent with the gas to be processed that flows into the device casing through the inflow port, the precoat agent nozzle is arranged at the inflow port. [0005] Conventionally, in Patent Document 1 figure 1 In the filter device shown in , a simple circu...
