Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, and particularly relates to a waste gas treatment device for environmental engineering. Background Technique

[0002] Waste gas purification mainly refers to the work of treating industrial waste gas generated in industrial sites, such as dust particles, flue gas and soot, odor gas, toxic and harmful gas. Common waste gas purification includes factory soot waste gas purification, workshop dust waste gas purification, organic waste gas purification, waste gas odor purification, acid-base waste gas purification, chemical waste gas purification, etc.

[0003] At present, when treating waste gas, it is generally first absorbed by a solution, and then filtered through a filter screen and discharged into the atmosphere. However, as the use time of the filter screen increases, the mesh holes may be blocked, resulting in the influence of the filtering effect. Moreover, the gas generally directly passes through the solution, and the contact surface with the solution is insufficient, so the absorption effect is not good. Based on this, we propose an improvement on a waste gas treatment device for environmental engineering. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a waste gas treatment device for environmental engineering, which can effectively solve the technical problems that the filter screen is easy to adhere to dust and block the mesh holes as the use time increases, and the contact area between the gas and the solution is insufficient, resulting in poor absorption effect in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A waste gas treatment device for environmental engineering includes a treatment barrel. A stirring paddle is rotatably connected at a position near the lower part inside the treatment barrel. An installation column is rotatably connected at a position near the upper end surface on one side of the treatment barrel. The output shafts of the stirring paddle and one end of the installation column both penetrate through the treatment barrel and are sleeved with a synchronization mechanism. An auxiliary barrel is fixedly sleeved at one end of the treatment barrel away from the installation column. An installation rod is movably sleeved inside the installation column and the auxiliary barrel. A soft brush is fixedly connected to the outer wall of the installation rod. A filter screen is arranged in the middle of the upper end surface of the treatment barrel. The soft brush is arranged directly below the filter screen and is attached to the lower end surface of the filter screen.

[0007] As a further scheme of the utility model, a motor is fixedly arranged on the outer wall of one side of the treatment barrel. The output end of the motor is fixedly connected to one end of the output shaft of the stirring paddle. A check valve is arranged on an air inlet pipe fixedly sleeved at the other end of the treatment barrel. A plurality of uniformly distributed air holes are opened at the upper end of the pipe body of the air inlet pipe located inside the treatment barrel.

[0008] As a further scheme of the utility model, a liquid inlet pipe is fixedly sleeved on one side of the upper end of the treatment barrel. A solenoid valve is rotatably arranged on the liquid inlet pipe.

[0009] As a further solution of the utility model, mounting strips are fixedly connected to the outer walls on both sides of the filter net, and the mounting strips are fixedly mounted on the outer wall of the treatment barrel through bolts.

[0010] As a further solution of the utility model, the synchronization mechanism includes a synchronous belt and two synchronous pulleys. The synchronous belt is sleeved on the outer walls of the two synchronous pulleys, and the synchronous belt meshes with the two synchronous pulleys. The two synchronous pulleys are respectively fixedly sleeved on the output shaft of the stirring paddle and the outer wall of the mounting column.

[0011] As a further solution of the utility model, an installation groove is opened on one side of the mounting column. Card slots are opened on the upper and lower inner walls of the installation groove. Sliding grooves are opened on the upper and lower outer walls at one end of the mounting rod. Two clamping blocks are slidably sleeved in the two sliding grooves respectively. Spring are fixedly connected between the two clamping blocks and the inner walls of the two sliding grooves respectively. The two clamping blocks are respectively movably sleeved in the two card slots, and one end of the mounting rod is movably sleeved in the installation groove.

[0012] As a further solution of the utility model, a disassembly handle is fixedly connected to one end of the mounting rod. One end of the disassembly handle protrudes from the auxiliary cylinder. A sealing sleeve is threadedly connected to the outer wall of the treatment barrel. The sealing sleeve is sleeved on the outer ends of the auxiliary cylinder and the disassembly handle.

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

[0014] By arranging the stirring paddle, the mounting column, the synchronization mechanism, the auxiliary cylinder, the mounting rod and the soft brush structure, the motor can drive the stirring paddle to stir the solution, increasing the contact area between the gas and the solution and improving the absorption effect of the solution. At the same time, the synchronization mechanism drives the mounting column to rotate, and then drives the soft brush to rotate through the mounting rod, cleaning the lower surface of the filter net in real time to avoid blockage of the mesh holes and affecting the filtering effect.

[0015] By opening an installation groove in the mounting column and opening card slots on the opposite inner walls of the installation groove, one end of the mounting rod is movably sleeved in the installation groove, and the clamping block is sleeved in the card slot. The mounting column can fix the mounting rod. At the same time, with the spring arranged in the sliding groove and the inclined plane structure of the clamping block, the mounting rod can be pressed against the mounting column side through the disassembly handle, causing the clamping block to automatically slide into the sliding groove. Then, after rotating the mounting rod to a suitable angle, the mounting rod can be conveniently disassembled from the mounting column, facilitating regular maintenance of the soft brush and preventing the soft brush from losing its cleaning effect, which has practicability.

Specific embodiments

[0021] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] As Figures 1-4 shown, an exhaust gas treatment device for environmental engineering includes a treatment barrel 1. A stirring paddle 4 is rotatably connected near the lower position inside the treatment barrel 1. A mounting column 5 is rotatably connected near the upper end surface on one side of the treatment barrel 1. The output shafts of the stirring paddle 4 and one end of the mounting column 5 both penetrate the treatment barrel 1 and are sleeved with a synchronization mechanism 6. An auxiliary barrel 9 is fixedly sleeved at one end of the treatment barrel 1 away from the mounting column 5. A mounting rod 10 is movably sleeved inside the mounting column 5 and the auxiliary barrel 9. A soft brush 11 is fixedly connected to the outer wall of the mounting rod 10. A filter screen 7 is arranged in the middle of the upper end surface of the treatment barrel 1. The soft brush 11 is arranged directly below the filter screen 7, and the soft brush 11 is arranged in contact with the lower end surface of the filter screen 7.

[0023] In this embodiment, a motor is fixedly arranged on the outer wall of one side of the treatment barrel 1. The output end of the motor is fixedly connected to one end of the output shaft of the stirring paddle 4. The stirring paddle 4 is driven by the motor to stir the solution. A liquid inlet pipe 3 is fixedly sleeved on the other end of the treatment barrel 1. A check valve is arranged on the liquid inlet pipe 3 to prevent the solution from flowing back. A plurality of uniformly distributed air holes are opened at the upper end of the pipe body of the liquid inlet pipe 3 located inside the treatment barrel 1 to improve the uniformity of the gas and solution mixture.

[0024] In this embodiment, a liquid inlet pipe 3 is fixedly sleeved on one side of the upper end of the treatment barrel 1. A solenoid valve is rotatably arranged on the liquid inlet pipe 3 to facilitate the on-off control of the liquid injection. At the same time, a solenoid valve is also arranged on the waste discharge pipe on one side of the lower end of the treatment barrel 1.

[0025] In this embodiment, mounting strips 8 are fixedly connected to the outer walls on both sides of the filter net 7. The mounting strips 8 are fixedly mounted on the outer wall of the treatment barrel 1 by bolts, which facilitates the disassembly and replacement of the filter net 7 in the later stage.

[0026] In this embodiment, the synchronization mechanism 6 includes a synchronous belt and two synchronous pulleys. The synchronous belt is sleeved on the outer walls of the two synchronous pulleys, and the synchronous belt meshes with the two synchronous pulleys. The two synchronous pulleys are respectively fixedly sleeved on the output shaft of the stirring paddle 4 and the outer wall of the mounting column 5. The synchronous belt drives the two synchronous pulleys to rotate, so that the output shaft of the stirring paddle 4 can drive the mounting column 5 to rotate.

[0027] In this embodiment, a mounting groove 14 is formed on one side of the mounting column 5. Card slots 15 are formed on the upper and lower inner walls of the mounting groove 14. Slide grooves 16 are formed on the upper and lower outer walls of one end of the mounting rod 10. Two clamping blocks 12 are slidably sleeved in the two slide grooves 16. Spring 13 is fixedly connected between the two clamping blocks 12 and the inner walls of the two slide grooves 16. The two clamping blocks 12 are respectively movably sleeved in the two card slots 15. One end of the mounting rod 10 is movably sleeved in the mounting groove 14. The mounting rod 10 can be fixed in the mounting groove 14 by the clamping blocks 12 being sleeved in the card slots 15.

[0028] In this embodiment, a disassembly handle 17 is fixedly connected to one end of the mounting rod 10. One end of the disassembly handle 17 protrudes from the auxiliary cylinder 9. The disassembly handle 17 is provided to facilitate the operation of the mounting rod 10. A sealing sleeve 18 is threadedly connected to the outer wall of the treatment barrel 1. The sealing sleeve 18 is sleeved on the outer ends of the auxiliary cylinder 9 and the disassembly handle 17. This part is sealed by the sealing sleeve 18 to prevent gas leakage through the auxiliary cylinder 9.

[0029] It should be noted that the present utility model is an exhaust gas treatment device for environmental engineering. When in use, the gas is introduced into the treatment barrel 1 through the intake pipe 2 for absorption. Due to the check valve on the intake pipe 2, the solution can be prevented from flowing back. Then, the motor is started to drive the stirring paddle 4 to rotate, and the solution added through the liquid inlet pipe 3 is stirred to increase the contact area between the gas and the solution and improve the absorption effect. At the same time, the output shaft of the stirring paddle 4 will drive the mounting column 5 to rotate synchronously through the synchronization mechanism 6. Since the clamping block 12 is sleeved in the card slot 15, the mounting rod 10 can be further driven to rotate, and then the soft brush 11 is driven to rotate to clean the lower surface of the filter net 7, preventing the surface mesh holes from being blocked and affecting the filtering effect.

[0030] When maintenance of the soft brush 11 is required after a period of use, first rotate and remove the sealing sleeve 18, then press the mounting rod 10 through the disassembly handle 17. Then, in cooperation with the inclined surface structure of the clamping block 12, the clamping block 12 will slide into the slide groove 16 until the clamping block 12 moves out of the card slot 15. Then, rotate the mounting rod 10 to an appropriate angle, and then pull the mounting rod 10 to extract it and the soft brush 11 from the auxiliary cylinder 9, which is convenient and time-saving.

[0031] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above-mentioned embodiments, and what is described in the above-mentioned embodiments and the specification is only to illustrate the principle of the present utility model.
