[0023] A further feature of this invention is that the exhaust chamber has ventilation openings inside.

[0024] By adopting the above technical solution, the spraying dust is drawn into the exhaust chamber from the ventilation opening by the internal fan, and the powder is extracted by the external fan.

[0025] The beneficial effects of this utility model are:

[0026] Powder air is drawn into the exhaust chamber by a fan and quickly filtered out through a filter screen inside the exhaust chamber. When the powder on the filter screen needs to be removed, simply operate the fixing component to move the old filter screen out of the exhaust chamber and simultaneously send the new filter screen into the exhaust chamber. This achieves a rapid cycle installation method, reducing downtime in the spray booth and ensuring the continuity and efficiency of the spraying operation. Attached Figure Description

Detailed Implementation

[0033] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0034] This utility model embodiment specifically provides a spray booth with powder recovery, please refer to... Figures 1-4 It includes a spray booth 1, an exhaust chamber 2, a fan 3, and a recycling component 4.

[0035] The exhaust chamber 2 is fixedly connected to the spray booth 1 on the outside. The fan 3 is fixedly installed on the exhaust chamber 2. The recovery component 4 is set on the exhaust chamber 2. The dust generated during spraying is sent to the recovery component 4 by the fan 3 for recovery, and the recovered gas is quickly discharged by the fan 3.

[0036] Specifically, exhaust vents 21 are provided on the upper and lower sides of the exhaust chamber 2 for the installation and use of the recycling component 4.

[0037] Furthermore, the recycling component 4 includes a drawer frame 41 that is inserted into the drawer opening 21 on the outside, a recycling net 42 that is detachably installed on the drawer frame 41, and an airtight block 43 fixed inside the drawer frame 41. The recycling net 42 filters the dust in the exhaust gas, and the powder can be removed by disassembling the recycling net 42.

[0038] The outer side of the airtight block 43 is inserted into the drawer 21, and the outer side of both the drawer frame 41 and the airtight block 43 are fitted to the drawer 21, thereby improving the airtightness of the exhaust chamber 2.

[0039] In practice, the number of recycling nets 42 is set in two or more places. The recycling net 42 includes a frame 421 whose bottom surface is bolted to the airtight block 43 and a filter 422 fixed inside the frame 421. The powder is filtered out through the filter 422. When it is necessary to clean the powder on the mesh opening, the bolts on the frame 421 can be unscrewed to remove the frame 421.

[0040] The drawer frame 41 is fixed to the exhaust chamber 2 by the fixing component 44, so that the drawer frame 41 can be fixed to the exhaust chamber 2 during daily use.

[0041] Specifically, the outer side of the drawer frame 41 is provided with slots 411 spaced apart, which cooperate with the fixing component 44.

[0042] In practice, the fixing component 44 includes an insert plate 441 that is inserted into the socket 411 on the outside, a rotating shaft 442 that is fixedly connected to the insert plate 441 at the bottom, and a mounting base 443 that is fixed to the bottom side of the exhaust chamber 2. The top end of the rotating shaft 442 is rotatably connected to the mounting base 443, so that the insert plate 441 can rotate through the rotating shaft 442 and be separated from or inserted into the socket 411.

[0043] A torsion spring 444 is installed between the rotating shaft 442 and the mounting base 443, so that the insert plate 441 can quickly return to its original position after rotation, so as to maintain the insertion with the socket 411.

[0044] The exhaust chamber 2 has ventilation openings 22 inside, and a fan 3 is installed at each of the left and right ends of the exhaust chamber 2. The internal fan 3 draws the spraying dust into the exhaust chamber 2 through the ventilation openings 22, and the external fan 3 extracts the powder.

[0045] By employing the aforementioned technology, the lower recycling net 42 is located inside the exhaust chamber 2, and is airtightly fitted with the extraction port 21 by the airtight blocks 43 at both ends of the recycling net 42. This allows the dust-laden airflow in the exhaust chamber 2 to be discharged onto the filter screen 422 for collection. When the recycling net 42 inside the exhaust chamber 2 needs cleaning, the insert plate 441 can be disconnected from the insertion port 411, and then the drawer frame 41 can be pulled down to move the internal recycling net 42 down and quickly replace it with the upper recycling net 42. The insert plate 441 can then be inserted into the new insertion port 411, and the old recycling net 42 that has been removed from the exhaust chamber 2 can be removed for recycling and cleaning. When cleaning is required after cleaning, simply move the drawer frame 41 up to reset it, and repeat this process.

[0046] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
