Description

Technical Field

[0001] The utility model relates to the field of paint mist recovery, in particular to a water curtain recovery device for sample detection. Background Art

[0002] During the detection process of paint samples, in order to ensure environmental cleanliness and effective utilization of resources, a water curtain recovery device is usually used to collect the overspray paint mist dissipated during the spraying process. The main function of this device is to form a "water curtain" through water flow to capture paint mist particles in the air, thereby reducing environmental pollution and recovering some paint materials.

[0003] In a water curtain recovery device, in order to save water resources and improve efficiency, a circulation system is usually set up. The water is pumped out from a collection pool or a water storage tank by a water pump and then re-supplied above the water curtain to form a new water curtain. This can continuously capture paint mist without causing a large amount of water waste. Installing an appropriate filtering device before the water pump is very crucial, which can help remove most of the larger paint particles and other impurities to prevent them from entering the pump and causing blockage or wear.

[0004] Currently, the commonly used filtering devices are generally sedimentation tanks, filter meshes, cartridge filters, etc. The sedimentation tank occupies a large area and has relatively low treatment efficiency; the filter mesh is mainly for large particles and is ineffective for fine particles; although the cartridge filter can filter fine particles, it is easy to be blocked after long-term use and is generally installed inside the device, making the replacement operation inconvenient. Summary of the Invention

[0005] The utility model aims to solve the deficiencies of the prior art and provides a water curtain recovery device for sample detection.

[0006] To achieve the above object, the present utility model adopts the following technical solutions: A water curtain recovery device for sample detection, comprising a housing. At the rear side of the inner bottom of the housing, there is a water collection tank, and at the front side, there is a sample support table. On both inner walls of the housing, there are double-layer water curtain plates, which are located above the water collection tank, and a water inlet pipeline is provided on the double-layer water curtain plates. On one side of the housing, there is a filter box communicated with the water collection tank. Inside the filter box, a double-layer filter screen plate is slidably inserted near the housing side. At the bottom of the filter box, away from the housing side, a pair of turntables are rotatably connected. On the filter box, there is a power mechanism for driving the turntables to rotate. On the top of the turntable, a filter element type filter is inserted. On the top of the filter box, there is a first jack corresponding to the filter element type filter. On the top side wall of the filter element type filter, a cover plate is rotatably connected. On the bottom edge of the cover plate, a plurality of insertion rods are evenly distributed in a circumferential manner, and are inserted into the first jack through the insertion rods. On the inner wall of the filter box, there is a scraping plate in contact with the outer wall of the filter element type filter. At the center of the top of the filter element type filter, a drain pipe is rotatably connected. In front of the filter box, a water pump is installed. Between the water inlet of the water pump and the drain pipe, a first water guide pipe is connected through a pipe joint. Between the water outlet of the water pump and the water inlet pipeline, a second water guide pipe is connected.

[0007] Specifically, a connecting plate is provided on the top of the double-layer filter screen plate, and a first handle is provided on the top of the connecting plate.

[0008] Specifically, on the front and rear inner walls of the filter box, there are sliding grooves corresponding to the double-layer filter screen plate. On the top of the filter box, there is a second jack corresponding to the double-layer filter screen plate. The double-layer filter screen plate passes through the second jack and is slidably inserted into the sliding groove.

[0009] Specifically, on the side wall of the filter element type filter passing through the filter box, there is a second handle.

[0010] Specifically, a drain port is connected to the second water guide pipe.

[0011] Specifically, at the bottom of the filter element type filter, there is a cross-shaped insertion block, and on the top of the turntable, there is a cross-shaped slot, and the insertion block is inserted into the slot.

[0012] Specifically, the power mechanism includes a motor. At the bottom of the filter box, away from the housing side, there is a groove. At the bottom of the turntable, there is a rotating shaft, and the rotating shaft is rotatably connected in the groove. Between the two rotating shafts, there is a belt drive. The motor is installed at the bottom of the side wall of the filter box, and between the main shaft of the motor and one rotating shaft, there is a belt drive.

[0013] The beneficial effects of the present utility model are:

[0014] By setting the double-layer water curtain plate in the present utility model, the first layer of water curtain captures most of the larger paint mist particles, and the small particles and fine aerosols not captured by the first layer will be further intercepted by the second layer of water curtain, improving the capture efficiency.

[0015] The utility model can significantly improve the overall filtration efficiency through a grading filtration method by setting a filter box, a double-layer filter screen plate, a connecting plate, and a first handle. The first-layer filter screen can capture larger paint particles, while the second-layer filter screen further captures finer particles. The double-layer filter screen plate is easy to replace.

[0016] The utility model can significantly improve the overall filtration efficiency by setting a turntable, a power mechanism, a filter cartridge type filter, a scraper, a cover plate, a second handle, and a drain pipe. The filter cartridge type filter rotates driven by the turntable, and the surface of the filter cartridge moves continuously. The paint particles attached to the filter cartridge are continuously removed by the scraper to maintain the effective filtration area of the filter cartridge. At the same time, the rotation helps to evenly distribute the water flow on the surface of the filter cartridge, avoiding local blockage, and the filter cartridge type filter is easy to replace.
