Description

Technical Field

[0001] This utility model relates to the field of powder coating workshop technology, specifically to a ventilation device with filtration function for powder coating workshops. Background Technology

[0002] A powder coating workshop is a highly efficient and environmentally friendly surface treatment facility, primarily used for uniformly spraying powder coatings onto workpiece surfaces. Due to its high efficiency, environmental friendliness, and superior coating quality, powder coating workshops are widely used in various fields, including metal and plastic products. When powder coating workpieces are being coated, ventilation equipment is generally required to ensure proper ventilation and protect the health of the workers.

[0003] Most existing ventilation equipment in powder coating workshops uses internal filters to filter dust. However, over time, these filters easily become clogged with dust, and existing ventilation equipment makes it inconvenient to quickly clean the dust off the filters. This clogged filters affect the ventilation speed and the overall ventilation effect of the equipment. Therefore, we propose a ventilation system with a filtration function for powder coating workshops. Utility Model Content

[0007] The outer side of the filter screen is equipped with a cleaning component, which includes a U-shaped frame. Both inner walls of the U-shaped frame are connected to elastic elements. Each set of elastic elements is equipped with a mounting side plate. A brush plate is connected between adjacent mounting side plates. A U-shaped seat is connected to the top of the ventilation duct, and an adjustment component for adjusting the position of the cleaning component is provided inside the U-shaped seat.

[0008] Furthermore: a vibration motor is connected to the outer wall of the U-shaped frame, and a vibration plate is connected to the output end of the vibration motor.

[0009] Furthermore: the adjusting component includes a geared motor, which is located on the outer wall of the U-shaped seat, and the output end of the geared motor is connected to a lead screw, the other end of which is rotatably connected to the inner wall of the U-shaped seat through a bearing.

A sliding block is slidably connected in the through groove, and the two ends of the sliding block are respectively connected to the threaded block and the U-shaped frame.

[0011] Furthermore: A connecting frame is installed on the side of the ventilation duct closest to the powder coating workshop, and mounting holes are provided at all four corners of the connecting frame.

[0012] Furthermore: the collection box is connected to the inner wall of the through hole by a snap-fit ​​mechanism.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The filter screen of this utility model can filter dust. The ventilation equipment in the powder coating workshop has a filtration function. By operating the vibrating motor on the cleaning component, the vibrating plate can be driven to vibrate, which in turn drives the brush plate to vibrate on the filter screen. The operation of the reduction motor on the adjusting component can drive the lead screw to rotate. After the threaded block connected to the lead screw slides and is limited by the through groove and the sliding block, the vibrating brush plate on the cleaning component can move on the filter screen, which can quickly clean the dust in different positions on the filter screen.
