Description

Technical Field

[0001] The utility model relates to a paint spraying waste gas collection chamber, in particular to a movable paint spraying waste gas collection chamber. Background Art

[0002] The paint spraying waste gas collection chamber is usually used for collecting waste gas during paint spraying processing. When it comes to paint spraying processing of large equipment and steel components, it is inconvenient for manual movement. Usually, overhead cranes or forklifts are used for hoisting and shifting. In order to ensure the working space, many factories mostly adopt open-air operation, and the waste gas directly escapes, which has a certain harm to the surrounding environment and the physical and mental health of operators.

[0003] For the existing fixed paint spraying chamber in the prior art, it is obvious that it is difficult for forklifts and overhead cranes to move the workpiece into the semi-closed paint spraying chamber; for the telescopic paint spraying chamber, it is inconvenient to perform air supply and collection at the top and side, and the limitations are relatively high; for the overall movable paint spraying chamber, some adopt pipeline butt joint collection, and the pipeline needs to follow the movement or be frequently disassembled and butt-jointed, with a high technical operation difficulty; the other part adopts the air collection form of top air supply and bottom excavation of underground air ducts, with a high construction difficulty, high cost, long construction period, and inconvenient cleaning and maintenance in case of blockage of the underground air duct in the later stage. And most paint spraying chambers do not consider the protective measures for dealing with emergency incidents, which have major potential hazards. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an overall movable paint spraying waste gas collection chamber. Aiming at the deficiencies in the prior art, the length and height dimensions of the water curtain cabinet correspond to the length and height of the front door opening of the waste gas collection chamber, so that the front door opening of the waste gas collection chamber can be spliced with the water curtain cabinet, and the rubber gasket is used for sealing at the gap. The water curtain cabinet is docked with the subsequent collection pipeline and the fan. A rolling shutter door is installed at the rear end to ensure the airtightness during paint spraying operation. An air supply device is arranged at the top to form the waste gas flow direction of top air supply and side air suction. The problems of difficult positioning of large workpieces during paint spraying, complex operation of the paint spraying chamber, difficult construction, and insufficient safety prevention measures are solved.

[0005] The technical solution of the utility model: A movable paint spraying waste gas collection chamber, characterized in that: it includes ground rails, pulleys, motors, waste gas collection chambers, rolling shutter doors, air supply fans, air boxes, water curtain cabinets, and fans; two parallel ground rails are laid and fixed on the ground, the pulleys are mounted on the ground rails, the pulleys are connected with the motors, the pulleys are connected with the waste gas collection chambers, the rolling shutter doors are installed at the rear end of the collection chamber, the air supply fans are installed at the top of the waste gas collection chamber, the air supply fans are connected with the air boxes, the waste gas collection chambers are docked with the water curtain cabinets, and the water curtain cabinets are connected with the fans through air ducts.

[0006] A safety door is installed on the side of the waste gas collection chamber.

[0007] A rupture disc is arranged at the top of the waste gas collection chamber.

[0008] Combustible gas detectors are installed on both inner sides of the waste gas collection room.

[0009] Explosion-proof lighting fixtures are installed on the beams of the waste gas collection room.

[0010] The air box is installed at the top of the waste gas collection room.

[0011] Louvers are provided at the bottom of the air box. Description of the Drawings

[0012] Figure 1 、 Figure 2 、 Figure 3 are the structural schematic diagrams of the present utility model.

[0013] The reference signs in the drawings are: ground rail 1, pulley 2, motor 3, waste gas collection room 4, rolling shutter door 5, air supply fan 6, air box 7, water curtain cabinet 8, fan 9, safety escape door 401, explosion vent panel 402, combustible gas detector 403, explosion-proof lighting fixture 404, louver 701. Detailed Embodiment

[0014] The present utility model will be further described below in conjunction with the drawings and embodiments, but it shall not be used as a basis for limiting the present utility model.

[0015] Embodiment. A mobile waste gas collection room for spray painting, which is composed as shown in Figure 1 、 Figure 2 、 Figure 3 , and includes a ground rail 1, a pulley 2, a motor 3, a waste gas collection room 4, a rolling shutter door 5, an air supply fan 6, an air box 7, a water curtain cabinet 8, and a fan 9 that are connected in sequence; two parallel ground rails 1 are laid and fixed on the ground, the pulley 2 is mounted on the ground rail, the pulley 2 is connected to the motor 3, the pulley 2 is connected to the waste gas collection room 4, the rolling shutter door 5 is installed at the rear end of the collection room 4, the air supply fan 6 is installed on the top of the waste gas collection room 4, the air supply fan 6 is connected to the air box 7, the waste gas collection room 4 is docked with the water curtain cabinet 8, and the water curtain cabinet 8 is connected to the fan 9 through an air duct.

[0016] A safety door 401 is installed on the side of the waste gas collection room 4.

[0017] An explosion vent panel 402 is provided at the top of the waste gas collection room 4.

[0018] Combustible gas detectors 403 are installed on both inner sides of the waste gas collection room 4.

[0019] Explosion-proof lighting fixtures 404 are installed on the beams of the waste gas collection room 4.

[0020] The air box 7 is installed at the top of the waste gas collection room 4.

[0021] Louvers 701 are provided at the bottom of the air box 7.

[0022] The working process of the utility model: the motor of the mobile exhaust gas collection room can be controlled by a remote controller, and the personnel can remotely control it nearby. When working, first retract the rear roller shutter door to prevent the scaffold in the collision area, move the exhaust gas collection room to an idle area, and shift the workpieces that need to be spray-painted to the scaffold in the original area of the exhaust gas collection room. Then move the exhaust gas collection room back to its original position, so that the front door opening is docked and fits with the water curtain cabinet, and then turn on the end exhaust fan, the top blower, and the lighting, close the roller shutter door, and the personnel enter from the side safety door to start the painting operation. The exhaust gas is guided by the air flow and pumped to the water curtain cabinet for discharge. The combustible gas detector installed in the room will sound an alarm if the concentration of the combustible gas reaches the explosion limit, reminding the operating personnel to evacuate quickly. If an accidental explosion occurs, the personnel can evacuate from the safety door, and the explosion relief plate on the top plays a role in pressure relief, reducing the scope of the explosion. By installing this type of exhaust gas collection room, not only can the exhaust gas be effectively collected, but also the initial investment can be saved, the subsequent operation and maintenance can be convenient, and security facilities can be added to improve the safety factor.
