DETAILED DESCRIPTION

[0037] In order for those skilled in the art to better understand the present application, the technical solutions of the present application are further described below in combination with the drawings and embodiments.

[0038] Embodiment one:

[0039] AsFigures 1 to 5 The exhaust gas purification treatment device shown includes a purification cylinder 100, the bottom of which is provided with a placing seat 101, and the lower end of the purification cylinder 100 is connected with an exhaust pipe 102 through a pipeline on one side, and a water storage chamber 103 is installed in the middle of the purification cylinder 100, and a purification mechanism is further installed inside the purification cylinder 100.

[0040] A V-shaped bottom plate 104 is fixedly installed at the bottom of the water storage chamber 103, and the lower end of the V-shaped bottom plate 104 is processed into a circular arc-shaped chamfer, the purification mechanism includes two communication platforms 105 and a filter screen 106, the two communication platforms 105 are symmetrically installed on the outer walls of the two sides of the purification cylinder 100, the lower ends of the two communication platforms 105 extend to the lower side of the V-shaped bottom plate 104, the upper ends of the two communication platforms 105 extend through to the inside of the purification cylinder 100, a plurality of air passages 107 are formed in the interiors of the two communication platforms 105, and a gas inlet pipe 108 extending downward to the lower side of the water storage chamber 103 is fixedly connected to the upper ends of the two communication platforms 105, the filter screen 106 is installed inside the water storage chamber 103, and the gas inlet pipe 108 penetrates downward through the filter screen 106, and the V-shaped bottom plate 104 is further fixedly connected with a plurality of drainage openings 109, and the V-shaped bottom plate 104 is further installed with a plugging mechanism 110 matched with the drainage openings 109.

[0041] The purification cylinder 100 is further installed with an activated carbon purification layer 111, which is located above the water storage chamber 103, and the lower end of the purification cylinder 100 is further installed with a drainage cover plate 112.

[0042] The plugging mechanism includes an electric telescopic rod 113, a round rod 114 and a plurality of rubber plugs 115, the telescopic end of the electric telescopic rod 113 is fixedly connected with a plurality of connecting rods 116, each connecting rod 116 is slid downward through the activated carbon purification layer 111 and the filter screen 106 in sequence, the lower ends of the connecting rods 116 are fixedly connected with the round rod 114, each rubber plug 115 is matched with each drainage opening 109, and each rubber plug 115 is fixedly arranged at the lower end of the round rod 114.

[0043] The purification cylinder 100 is placed through the placing seat 101, and the exhaust gas enters the interior of the purification cylinder 100 through the exhaust pipe 102 for purification treatment, in the initial state, as shown in Figure 4 and Figure 5 The electric telescopic rod 113 of the plugging mechanism drives the connecting rods 116 to make the rubber plugs 115 of the round rod 114 inserted into the drainage openings 109 of the V-shaped bottom plate 104, so that the V-shaped bottom plate 104 is plugged, and then the water storage chamber 103 is filled with water, so that the water surface is higher than the filter screen 106, at this time, the gas inlet pipe 108 of the communication platform 105 is immersed in water;

[0044] After the exhaust gas is introduced into the purification cylinder 100, the V-shaped bottom plate 104 at the bottom of the water storage chamber 103 is blocked, so that the exhaust gas enters the inlet pipe 108 through the air duct 107 inside the communication platform 105 on both sides. The dust and impurities in the exhaust gas will remain in the water storage chamber, thereby removing the dust and impurities in the exhaust gas. Since the inlet pipe 108 penetrates the filter screen 106 downward, the dust and impurities in the exhaust gas will adhere to the lower surface of the filter screen 106 under the action of buoyancy. After the dust and impurities are removed, the exhaust gas enters the activated carbon purification layer 111, and the activated carbon purification layer 111 further removes the particulate impurities in the exhaust gas through adsorption, so that the exhaust gas is discharged after dust and impurities removal and particulate impurities removal, thereby achieving good exhaust gas purification effect.

[0045] After the exhaust gas is purified, as shown in Figure 2 and Figure 3 , the circular rod 114 is moved upward by the electric telescopic rod 113, so that each rubber plug 115 is separated from each drain port 109. The water in the water storage chamber 103 is discharged downward to each drain port 109 of the V-shaped bottom plate 104. With the direction of the water flow, the filter screen 106 is washed by the water flow, so that the dust and impurities on the lower surface of the filter screen 106 can flow out with the water flow. By opening the drain cover plate 112 of the purification cylinder 100, the sewage is discharged, and the filter screen 106 can also be kept clean.

[0046] As a further description of the embodiment, the water storage chamber 103 is also provided with a water replenishing valve for connecting an external water pump. The water pump and the water replenishing valve can pump water into the water storage chamber 103, thereby achieving water replenishment of the water storage chamber 103.

[0047] Embodiment two:

[0048] Based on the first embodiment, in order to further collect and clean the dust and impurities filtered by the filter screen 106, as shown in Figures 6 to 9 , a V-shaped screen 200 is further arranged below the V-shaped bottom plate 104. The V-shaped screen 200 has the same specification as the filter screen 106, and is matched with the V-shaped bottom plate 104. The V-shaped screen 200 is provided with a sliding cylinder 201 at both ends matched with the two sides of the V-shaped bottom plate 104. A first positioning rod 202 matched with the sliding cylinder 201 is fixedly connected to the inner wall of the purification cylinder 100. A triangular sealing plate 203 is fixedly connected to one side of the V-shaped screen 200. A triangular through slot 204 matched with the triangular sealing plate 203 is arranged in the purification cylinder 100. A fixed assembly is arranged between the side of the V-shaped screen 200 close to the triangular sealing plate 203 and the purification cylinder 100.

[0049] In the initial state, as shown in Figure 6 and Figure 7As shown, the V-shaped screen 200 is capable of sliding into the inside of the purification cylinder 100 through the cooperation of the sliding cylinder 201 and the first positioning rod 202, and the triangular sealing plate 203 seals the triangular through slot 204 of the purification cylinder 100, and the fixed assembly fixes the V-shaped screen 200 and the purification cylinder 100.

[0050] After the exhaust gas is purified, the water in the water storage chamber 103 is discharged downward through each of the drain holes 109 of the V-shaped bottom plate 104, and the water flow direction allows the water to flush the filter screen 106, so that the dust and impurities on the lower surface of the filter screen 106 can flow out into the V-shaped screen 200. Since the V-shaped screen 200 has the same specifications as the filter screen 106, the V-shaped screen 200 can also screen out dust and impurities. After the water in the water storage chamber 103 is completely discharged, the fixed assembly is loosened, and the V-shaped screen 200 is pulled out. At this time, as shown in Figure 8 and Figure 9 As shown, the dust and impurities in the V-shaped screen 200 can be collected and cleaned.

[0051] As a further description of the embodiment, as shown in Figure 7 and Figure 9 The fixed assembly includes two first magnetic blocks 205 and two second magnetic blocks 206, and the first magnetic blocks 205 and the second magnetic blocks 206 are magnetically fixed. The two first magnetic blocks 205 are respectively arranged at the ends of the two sliding cylinders 201, and the two second magnetic blocks 206 are fixedly installed on the outer wall of the purification cylinder 100. The first magnetic blocks 205 and the second magnetic blocks 206 are magnetically connected, so that the V-shaped screen 200 can be fixed on the outer wall of the purification cylinder 100. At the same time, as shown, the triangular sealing plate 203 is also fixedly connected with a pull handle 207, and the first magnetic blocks 205 and the second magnetic blocks 206 can be pulled apart by pulling the pull handle 207, so as to pull the V-shaped screen 200. The structure is simple and convenient to use.

[0052] Embodiment Three:

[0053] On the basis of Embodiment Two, in order to make the device have the function of pre-purification, and avoid large impurities from entering the purification mechanism, as shown in Figures 10 to 13As shown, the purification cylinder 100 is located below the water storage chamber 103, and two circular arc plates 300 are symmetrically processed on both sides. A pre-purification mechanism is installed between the two circular arc plates 300. The pre-purification mechanism comprises a hinged seat 301 and a mesh plate 302. The hinged seat 301 is installed inside the purification cylinder 100. The mesh plate 302 is symmetrically hinged on both sides of the hinged seat 301. The two mesh plates 302 are matched with the two circular arc plates 300 respectively. Third magnetic blocks 303 are installed on the upper surfaces of the ends of the two mesh plates 302. Fourth magnetic blocks 304 with the same magnetic pole as the third magnetic blocks 303 are installed on the two communication platforms 105. A plurality of air floating balls 305 are also installed on the upper surfaces of the ends of the two mesh plates 302.

[0054] A reciprocating scraping mechanism is also arranged on the lower surface of the mesh plate 302. The reciprocating scraping mechanism comprises two slide rails 306, a slide rod 307, a first connecting frame 308, and a scraper roller 309. The two slide rails 306 are installed on both sides of the mesh plate 302 respectively. The slide rod 307 is slidably connected with the two slide rails 306 respectively. Positioning holes are formed on both sides of the slide rod 307. Second positioning rods 310 are arranged in the two slide rails 306 and slidably penetrate the positioning holes. The scraper roller 309 is matched with the lower surface of the mesh plate 302. The scraper roller 309 is fixed with the second positioning rods 310 through the first connecting frame 308. A stop block 311 is arranged at the lower end of the circular arc plate 300.

[0055] In the initial state, as shown in the figure, Figures 10 to 11 The mesh plate 302 rotates to the lower end of the circular arc plate 300 under the action of gravity relative to the hinged seat 301. Through the abutment of the mesh plate 302 and the stop block 311, the mesh plate 302 will not be separated from the lower end of the circular arc plate 300. The slide rod 307, the connecting frame 308, and the scraper roller 309 also move to the end of the mesh plate 302 under the action of gravity, following the slide rail 306. The slide rod 307 is prevented from rotating through the cooperation of the second positioning rod 310 and the positioning hole;

[0056] After the exhaust gas enters the purification cylinder 100, the exhaust gas flows upward, pushing the mesh plate 302 and filtering out the larger impurities of the exhaust gas on the lower surface of the mesh plate 302. The plurality of air floating balls 305 can further rotate the mesh plate 302 relative to the hinged seat 301, so that the end of the mesh plate 302 moves to the upper end of the circular arc plate 300, as shown in the figure, Figures 12 to 13As shown, in this process, the scraper 309 is moved from the end of the screen plate 302 to the side of the screen plate 302 close to the hinged seat 301, so that the larger impurities are scraped off the lower surface of the screen plate 302, and the fourth magnetic block 304 of the communication table 105 and the third magnetic block 303 of the screen plate 302 have the same magnetic pole, so that the third magnetic block 303 and the fourth magnetic block 304 repel each other, and the end of the screen plate 302 is pushed to rotate to the lower side of the circular arc plate 300, and the scraper 309 can be moved to the end of the screen plate 302, so that the scraper 309 can scrape off the larger impurities from the lower surface of the screen plate 302 again, and with the continuous entry of the exhaust gas and the repelling effect of the third magnetic block 303 and the fourth magnetic block 304, the screen plate 302 is continuously reciprocated, and the scraper 309 can move back and forth on the lower surface of the screen plate 302 to scrape off the larger impurities;

[0057] After the exhaust gas is purified and treated, the water in the water storage chamber 103 is discharged, and the screen plate 302 returns to the initial state because the exhaust gas is not entering. Since the water in the water storage chamber 103 is filtered by the V-shaped screen 200, the water flowing downward can flow out through the screen plate 302, and the water flows through the pores of the screen plate 302 in the direction of the water flow, which can clean the screen plate 302, so that the screen plate 302 is cleaned.

[0058] As a further illustration of the present embodiment, as shown, Figure 10 The second connecting frame 312 is fixedly arranged on the upper end of the purification cylinder 100, extends upward above the purification cylinder 100, and is fixedly connected with the rain cover 313. The rain cover 313 installed through the second connecting frame 312 can prevent rain when the device is used outdoors, so as to avoid rainwater from entering the purification cylinder 100.

[0059] The above embodiments are only illustrative of the principles and effects of the present application, and are not intended to limit the present application. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present application. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical idea disclosed by the present application should be covered by the claims of the present application.
