Description

Technical Field

[0001] The utility model relates to the field of sewage treatment, in particular to a device for synchronously purifying waste gas in sewage treatment. Background Technique

[0002] Industrial three wastes refer to the abbreviations of waste gas, waste water, and waste residue discharged during the industrial production process. Among them, industrial waste gas refers to various gases that are no longer used during the industrial production process, including soot, odor, irritating gases, and other harmful gases. Industrial waste water, that is, industrial sewage, refers to the sewage discharged during the industrial production process, which has exited the circulation system after use and contains various organic substances, inorganic substances, and toxic substances.

[0003] Nowadays, when treating sewage and waste gas, they are often treated separately, resulting in low overall treatment efficiency. Moreover, there is often a certain amount of waste gas in the sewage, and this part of the waste gas cannot effectively enter the waste gas treatment center along with the sewage. Content of the Utility Model

[0004] The purpose of the utility model is to provide a device for synchronously purifying waste gas in sewage treatment to solve the problems raised in the above background technique.

[0005] The utility model solves its technical problems by adopting the following technical solutions:

[0006] A device for synchronously purifying waste gas in sewage treatment includes a sewage tank. A drainage part is fixedly arranged at the right end of the sewage tank. Two intercepting filters are slidably installed between the front and rear side walls in the inner cavity of the sewage tank. At the position where the two intercepting filters are close to the drainage part, a fixing column is fixedly connected to the upper end surface of each intercepting filter. Two transverse sliding plates are slidably installed left and right on the right end surface of the sewage tank. An inverted V-shaped groove is arranged on the front transverse sliding plate, and a V-shaped groove is arranged on the rear transverse sliding plate. The cylindrical part at the top of the fixing column on the left is slidably installed in the inverted V-shaped groove, and the cylindrical part at the top of the fixing column on the right is slidably installed in the V-shaped groove. The right end surfaces of the two transverse sliding plates are fixedly connected to a connecting plate, and a return spring is connected between the connecting plate and the right end surface of the sewage tank. A roller part is rotatably installed between the front and rear side walls in the inner cavity of the sewage tank. Water deflecting plates are equidistantly distributed and installed on the outer end surface of the roller part, and each water deflecting plate can abut against the transverse sliding plate.

[0007] Preferably, strip-shaped openings are equidistantly distributed and penetrated in the arc section of each water deflecting plate, and water-containing grooves are equidistantly distributed and arranged on the outer end surface of the end hook part of each water deflecting plate.

[0008] Preferably, the surface of the arc section of the water deflecting plate is smooth.

[0009] Preferably, a driving motor is fixedly installed on the front side end face of the sewage tank. The output end of the driving motor is fixedly connected to a rotating shaft, and the rotating shaft is fixedly connected to the roller part.

[0010] Preferably, a water inlet part is arranged on the left side end face of the sewage tank. An air inlet pipe and a water inlet pipe are fixedly installed on the left side end face of the water inlet part, and both the air inlet pipe and the water inlet pipe are communicated with the inner cavity of the sewage tank.

[0011] Preferably, an air suction fan is fixedly installed on the upper end face of the sewage tank, and an air outlet pipe is fixedly installed at the air outlet of the air suction fan.

[0012] Preferably, a water outlet pipe is fixedly installed on the right side end face of the drainage part.

[0013] The advantages and positive effects of the present utility model are:

[0014] By arranging two staggered and sliding-up-and-down intercepting filter meshes at the drainage outlet of the sewage, the impurities in the sewage are filtered and intercepted. While ensuring the filtration of the sewage, the impurities attached to the intercepting filter mesh can be shaken off, thus effectively avoiding the blockage of the intercepting filter mesh. At the same time, during the rotation process, the water deflecting plate will bring the sewage out to the upper side of the water surface, so as to adsorb some dust impurities in the waste gas to a certain extent by using the sewage, thus facilitating the subsequent treatment of the waste gas;

[0015] At the same time, when the water deflecting plate stirs in the sewage, the residual gas in the sewage can also be stirred out, so that it is sucked into the waste gas together with the waste gas by the air suction fan and passed through the air outlet pipe for post-treatment of the waste gas.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0027] The following will further describe the embodiments of the present utility model in detail with reference to the attached drawings:

[0028] Please refer to Figures 1-3, an embodiment provided by the present utility model: a sewage treatment and waste gas synchronous purification device, including a sewage tank 10, and a water inlet part 11 is arranged on the left end face of the sewage tank 10.On the left end face of the water inlet part 11, an air inlet pipe 12 and a water inlet pipe 13 are fixedly installed. Both the air inlet pipe 12 and the water inlet pipe 13 are communicated with the inner cavity of the sewage tank 10. The air inlet pipe 12 is a pipe for waste gas to enter, and the water inlet pipe 13 is a pipe for sewage to enter. A drainage part 17 is fixedly installed on the right end face of the sewage tank 10 as the water outlet area. The water outlet pipe 18 is connected to the drainage part 17 for drainage. In the inner cavity of the sewage tank 10, two intercepting filter nets 23 are slidably installed between the front and rear side walls. At the position where the two intercepting filter nets 23 are close to the drainage part 17, a fixing column 22 is fixedly connected to the upper end face of each intercepting filter net 23. On the right end face of the sewage tank 10, two transverse sliding plates 20 are slidably installed left and right. An inverted V-shaped groove 21 is provided on the front transverse sliding plate 20, and a V-shaped groove 29 is provided on the rear transverse sliding plate 20. The cylindrical part at the top of the left fixing column 22 is slidably installed in the inverted V-shaped groove 21, and the cylindrical part at the top of the right fixing column 22 is slidably installed in the V-shaped groove 29, so that the two intercepting filter nets 23 are longitudinally offset from each other. A connecting plate 19 is fixedly connected to the right end faces of the two transverse sliding plates 20. A return spring is connected between the connecting plate 19 and the right end face of the sewage tank 10. A roller part 25 is rotatably installed between the front and rear side walls in the inner cavity of the sewage tank 10. Five water deflecting plates 26 are equidistantly distributed and installed on the outer end face of the roller part 25. Each water deflecting plate 26 can abut against the transverse sliding plate 20. When the roller part 25 rotates clockwise, it will drive the water deflecting plate 26 to rotate. When the water deflecting plate 26 abuts against the arc surface at the left end of the transverse sliding plate 20, it will push the transverse sliding plate 20 to slide to the right, so that the corresponding fixing column 22 slides along the inverted V-shaped groove 21 and the V-shaped groove 29. When the left intercepting filter net 23 slides upward, the right intercepting filter net 23 will slide downward. The two intercepting filter nets 23 slide up and down in an interlaced manner, and there will always be a bottom of one of the intercepting filter nets 23 abutting against the bottom of the sewage tank 10 to filter and intercept impurities in the sewage. While ensuring the filtration of sewage, it can also shake off the impurities attached to the intercepting filter net 23, effectively avoiding the blockage of the intercepting filter net 23. At the same time, during the rotation of the water deflecting plate 26, it will extend into the sewage and when it rotates out to the left position, it will bring the sewage out to the upper side of the water surface. The waste gas entering the water inlet pipe 13 will come into contact with the brought sewage, so as to adsorb some dust impurities in the waste gas to a certain extent by the sewage, which is convenient for subsequent treatment of the waste gas. At the same time, the water deflecting plate 26 agitates in the sewage and can also stir out some residual gas in the sewage, so that it is inhaled together with the waste gas by the suction fan 14 and passed through the air outlet pipe 15 for post-treatment of the waste gas.

[0029] It is worth mentioning that, in this embodiment, strip-shaped openings 27 are equidistantly distributed and penetrate through each of the water deflecting plates 26 in the arc section, and water collecting grooves 28 are equidistantly distributed and arranged on the outer end surfaces of the end hooked portions of each of the water deflecting plates 26. By using the opened strip-shaped openings 27, it is convenient for the water deflecting plates 26 to move in the sewage, reducing the resistance of water. At the same time, a little sewage can be filled in the water collecting grooves 28. After the water deflecting plates 26 rotate to the upper side of the water surface, the sewage in the water collecting grooves 28 will fall, thereby increasing the amount of sewage brought out of the water surface and further enhancing the contact with the waste gas.

[0030] It should be noted that, in order to facilitate the water deflecting plate 26 to abut against the transverse sliding plate 20 and drive the transverse sliding plate 20 to slide, in this embodiment, the surface of the arc section of the water deflecting plate 26 is made smooth.

[0031] In addition, in one embodiment, a driving motor 16 is fixedly installed on the front end surface of the sewage tank 10. The output end of the driving motor 16 is fixedly connected to a rotating shaft 24, and the rotating shaft 24 is fixedly connected to the roller part 25.

[0032] During specific implementation, sewage is introduced into the inner cavity of the sewage tank 10 through the water inlet pipe 13, and waste gas is introduced into the inner cavity of the sewage tank 10 through the air inlet pipe 12. At this time, the driving motor 16 is started, thereby driving the roller part 25 to rotate and driving the water deflecting plate 26 to rotate. When the water deflecting plate 26 abuts against the arc surface at the left end of the transverse sliding plate 20, it will push the transverse sliding plate 20 to slide to the right, so that the corresponding fixed column 22 slides along the inverted V-shaped groove 21 and the V-shaped groove 29. When the intercepting filter screen 23 on the left slides upward, the intercepting filter screen 23 on the right will slide downward. The two intercepting filter screens 23 slide up and down alternately, and there will always be a bottom of one of the intercepting filter screens 23 abutting against the bottom of the sewage tank 10 to filter and intercept impurities in the sewage. While ensuring the filtration of sewage, it can also shake off the impurities attached to the intercepting filter screen 23, thereby effectively preventing the intercepting filter screen 23 from being blocked. At the same time, during the rotation process, the water deflecting plate 26 will extend into the sewage, and when it rotates out to the left position, it will bring the sewage out to the upper side of the water surface. The waste gas entering through the air inlet pipe 13 will come into contact with the sewage brought out, so that some dust impurities in the waste gas can be adsorbed to a certain extent by the sewage, thereby facilitating the subsequent treatment of the waste gas. At the same time, the water deflecting plate 26 stirs in the sewage, and can also stir out some residual gas in the sewage, so that it is inhaled together with the waste gas by the suction fan 14 and undergoes post-treatment of the waste gas through the air outlet pipe 15.

[0033] It should be emphasized that the embodiments described in the present utility model are illustrative rather than restrictive. Therefore, the present utility model is not limited to the embodiments described in the specific embodiments. Any other embodiments obtained by those skilled in the art based on the technical solutions of the present utility model also fall within the scope of protection of the present utility model.
