Description

Technical Field

[0001] The utility model relates to the technical field of paint spraying waste gas treatment, in particular to an environmental protection device for paint spraying waste gas treatment. Background Art

[0002] Spray painting is a surface treatment technology, usually used on metal, plastic, wood or other materials to give them anti-corrosion, wear resistance, decorative or special functions. Spray painting waste gas is mainly produced during the spraying process. Liquid paint forms atomized dust particles and volatile organic waste gas under the action of air pressure. The components of these waste gases mainly include benzene, alkanes, cycloalkanes, olefins, aromatic compounds, alcohols, aldehydes, ketones, esters, ethers and other compounds. Spray painting waste gas is very harmful to the human body and the surrounding environment. In order to treat spray painting waste gas, environmental protection equipment is needed.

[0003] Common environmental protection devices for the treatment of paint waste gas are usually composed of structures such as a collection system, a pretreatment device, an activated carbon adsorption device, and an emission system. The paint waste gas is first injected into the device through the collection system, and then treated by the pretreatment device and the activated carbon adsorption device, and then discharged by the emission system. This is the common structure and use of environmental protection devices for the treatment of paint waste gas. In traditional environmental protection devices for the treatment of paint waste gas, since the paint waste gas contains dust particles and volatile organic waste gas, it is necessary to separate the dust particles in the waste gas through a filter screen. The dust particles block the filter screen, causing the device to be unable to be used normally. Some environmental protection devices for the treatment of paint waste gas are equipped with a drive motor and a scraper on the filter screen, and the rotating scraper can clean the filter screen. However, although this method can treat the filter screen, due to the high temperature of the paint waste gas itself, it will cause deformation or damage to the filter screen, thereby reducing the service life of the filter screen. For this reason, a paint waste gas treatment environmental protection device is proposed. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies in the prior art, the utility model provides an environmental protection device for treating paint waste gas to solve the technical problem that the temperature of the paint waste gas itself is too high, causing damage to the filter screen.

[0006] (II) Technical solution

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a paint spraying waste gas treatment and environmental protection device, comprising:

[0008] A device housing, and an air intake pipe arranged at the lower part of one side of the device housing, and a first drive motor is added at the bottom center of the device housing, a heat exchange tube is installed at the lower part of the inner cavity of the device housing, and the heat exchange tube is designed in an S shape as a whole;

[0009] The upper connecting seat is arranged at the lower center of the inner cavity of the device shell, and an upper ring hole plate is additionally installed on the top of the upper connecting seat;

[0010] The lower connecting seat is arranged at the bottom of the upper connecting seat, and the top of the lower connecting seat is rotatably connected with a lower annular plate, and corresponds to the upper annular plate. The lower annular plate is coaxially connected to the first driving motor, and air guide side plates are installed around the bottom of the lower annular plate. After the exhaust gas is injected into the inner cavity of the device shell through the air intake pipe and rises, the heat exchange medium can be introduced into the heat exchange tube to flow and perform heat exchange operations with the exhaust gas. After the first driving motor drives the lower annular plate to rotate on the lower connecting seat and is correspondingly connected to the upper annular plate of the upper connecting seat, the exhaust gas can rise along the air guide side plate through the lower annular plate and the upper annular plate. On the one hand, the heat in the exhaust gas can be processed, which not only avoids deformation or damage to the filter plate, but also can reuse the heat; on the other hand, the S-shaped heat exchange tube and the rotating lower annular plate can increase the contact area and contact time between the exhaust gas and the heat exchange tube, so that the heat in the exhaust gas can be effectively exchanged.

[0011] Preferably, an exhaust head is installed on the top of the device housing, and a filter screen is installed on the upper part of the inner cavity of the device housing, and a second drive motor is added above the top of the filter screen. The treated exhaust gas can be discharged or guided to the inside of other treatment equipment through the exhaust head, and the filter screen can separate and treat particulate matter in the exhaust gas.

[0012] Preferably, the second drive motor is located at the top center of the exhaust head, and lower scrapers are provided around the bottom of the filter screen and are coaxially connected to the second drive motor. The second drive motor drives the lower scraper at the top of the exhaust head to rotate at the bottom of the filter screen, thereby scraping off the particles intercepted by the filter screen to avoid blockage at the bottom of the filter screen, which causes the exhaust gas to be unable to pass.

[0013] Preferably, a third drive motor is vertically installed on both sides of the center position of the back of the device shell, and a material guide plate is rotatably connected to the center position of both sides of the device shell and is coaxially connected to the third drive motor. The third drive motor drives the material guide plate to rotate on the device shell, so that the two sets of material guide plates are connected just below the bottom of the filter screen plate, thereby bonding the particles scraped off the filter screen plate, and then resetting them under the action of the third drive motor, so that the particles scraped off the filter screen plate can be discharged, avoiding the phenomenon that the particles are difficult to clean or accumulate inside the device shell.

[0014] Preferably, a collecting plate is installed horizontally at the lower center of the outer side of the guide plate, and a side scraper is vertically installed at the upper center of the outer side of the guide plate. The side scraper can be used to scrape off the particles adhering to the surface of the guide plate, and the particles are sticky and adhere to the top of the collecting plate, so that the guide plate can be cleaned and the particles can be collected on the collecting plate for collection and processing.

[0015] Preferably, hydraulic rods are vertically installed at the upper center positions of both sides of the device housing, and the telescopic ends of the hydraulic rods are connected to the tops of the corresponding side scrapers. The hydraulic rods drive the side scrapers to perform lifting and reciprocating motions on the device housing.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the utility model provides an environmental protection device for treating paint waste gas, which has the following beneficial effects:

[0018] The environmental protection device for treating paint waste gas can inject waste gas into the inner cavity of the device shell through the air inlet pipe and then introduce heat exchange medium into the heat exchange tube to exchange heat with the waste gas. The first drive motor drives the lower annular plate to rotate on the lower connecting seat, and after being connected with the upper annular plate of the upper connecting seat, the waste gas can rise along the air guide side plate through the lower annular plate and the upper annular plate. In this way, on the one hand, the heat in the waste gas can be processed, which not only avoids deformation or damage to the filter plate, but also can reuse the heat; on the other hand, the S-shaped heat exchange tube and the rotating lower annular plate can increase the contact area and contact time between the waste gas and the heat exchange tube, so that the heat in the waste gas can be effectively exchanged.

[0026] See also Figure 2 The upper connecting seat 5 is arranged at the lower center of the inner cavity of the device housing 1, and an upper ring plate 6 is additionally installed on the top of the upper connecting seat 5;

[0027] The lower connecting seat 7 is arranged at the bottom of the upper connecting seat 5, and the top of the lower connecting seat 7 is rotatably connected with the lower annular plate 8, and corresponds to the upper annular plate 6. The lower annular plate 8 is coaxially connected to the first driving motor 3, and the bottom of the lower annular plate 8 is equipped with an air guide side plate 9. After the exhaust gas is injected into the inner cavity of the device housing 1 through the air intake pipe 2 and rises, the heat exchange medium can be introduced into the heat exchange tube 4 to flow and perform heat exchange operation with the exhaust gas.

The third drive motor 13 drives the guide plate 14 to rotate on the device housing 1, so that the two groups of guide plates 14 are connected directly below the bottom of the filter screen plate 10, thereby bonding the particles scraped off the filter screen plate 10, and then resetting them under the action of the third drive motor 13. The hydraulic rod 15 drives the side scraper 16 to perform lifting and reciprocating motion on the device housing 1 to scrape off the particles adhered to the surface of the guide plate 14, and adhere to the top of the collecting plate 18 due to the stickiness of the particles.
