DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] Embodiment 1

[0027] like Figure 1As shown, a harmful gas treatment device for environmental protection engineering includes a receiving plate 3, the four corners of the lower end of the receiving plate 3 are fixedly connected to support columns 4, the front side of the upper end of the receiving plate 3 is fixedly connected to a water tank 2, the upper end of the water tank 2 is fixedly connected to a water injection pipe 1 connected to the inner cavity of the water tank 2, the lower side of the front end of the water tank 2 is fixedly connected to a drainage pipe connected to the inner cavity of the water tank 2, the upper side of the rear end of the water tank 2 is fixedly connected to an air pipe 7 connected to the inner cavity of the water tank 2, the rear end of the air pipe 7 is fixedly connected to a cleaning device 5 connected to the inner cavity of the air pipe 7, the upper end of the cleaning device 5 is fixedly connected to an outer shell 6, and the air pipe 7 and the outer shell 6 are both fixedly connected to the receiving plate 3.

[0028] During the implementation of this embodiment, disinfectant water is first injected into the water storage tank 2 through the water injection pipe 1, and then the harmful gas is collected and transported to the cleaning device 5. Then, the solid particles in the gas are preliminarily filtered through the cleaning device 5. At the same time, the cleaning device 5 is used to automatically clean the filter component, which reduces the labor pressure of the staff and does not need to stop the operation of the device. Then, the filtered gas is transported into the water storage tank 2 through the gas pipe 7, treated with disinfectant water, and then discharged through the drain pipe.

[0029] Specifically, in order to ensure the continuity of harmful gas treatment, refer to Figure 2 and Figure 3 In this embodiment, a storage box 21 is slidably connected to the front side of the upper end of the water storage tank 2, and an activated carbon filter plate is slidably connected to the inner surface of the storage box 21;

[0030] For further information, see Figure 2 In this embodiment, the rear side of the gas delivery pipe 7 is placed at the lower part of the inner cavity of the water storage tank 2;

[0031] For further information, see Figure 3 In this embodiment, the upper and lower sides of the front end of the housing 6 are rotatably connected to the cabinet door 61, and the lower part of the housing 6 is tilted downward;

[0032] For further information, see Figure 3 In this embodiment, the cleaning device 5 includes a vent pipe 56, and a slide groove 51 is provided on the front side of the upper end and the rear side of the lower end of the vent pipe 56. The inner surfaces of the two slide grooves 51 are slidably connected with filter plates 52. The ends of the two filter plates 52 close to each other are fixedly connected with a connecting plate 53, and the right end of the filter plate 52 located at the lower part is fixedly connected with a driving component 54;

[0033] For further information, see Figure 3 In this embodiment, the front part of the vent pipe 56 is tilted downward, and the vent pipe 56 is fixedly connected to the receiving plate 3;

[0034] It can be seen that when harmful gas passes through the ventilation pipe 56, the filter plate 52 is used to initially filter solid particles in the harmful gas. As the device is used for a longer time, the filter plate 52 may be blocked. At this time, the drive assembly 54 can be started to move the used filter plate 52 upward or downward. At the same time, the unused filter plate 52 can be replaced into the ventilation pipe 56. Under the action of the connecting plate 53, the two filter plates 52 and the connecting plate 53 form a whole partition, so that the harmful gas will be filtered through any one of the filter plates 52 before being transmitted during the switching process of the two filter plates 52.

[0035] At the same time, during the switching process, the driving assembly 54 can be used to drive the filter plates 52 on the upper and lower sides to start rotating to sweep the filter plates 52 on the same side. The filter plates 52 can be cleaned and replaced without stopping the device. The swept impurities fall on the upper end of the ventilation pipe 56 and the bottom wall of the inner surface of the shell 6, and fall on the rear of the cabinet door 61 along the written cross section. After the processing is completed, the upper and lower cabinet doors 61 can be opened respectively to collect and process the impurities.

[0036] The filtered gas is transported through the gas pipe 7 to the disinfectant water inside the water tank 2 for disinfection. The disinfected gas is discharged to the outside through the storage box 21. After using it for a period of time, the storage box 21 can be pulled upward to replace the activated carbon filter plate inside the storage box 21. After the device is used, the sewage can be discharged through the drain pipe.

[0037] Specifically, in order to save costs and improve the practicality of the device, refer to Figure 4 and Figure 5 In this embodiment, the driving assembly 54 includes a motor 541, a rotating shaft 545 and two cleaning rods 544. The motor 541 is fixedly connected to a threaded rod 546 rotatably connected to the vent pipe 56 through a coupling at the output end. A connecting ring 543 is threadedly connected to the outer surface of the threaded rod 546. Two meshing bevel gears 542 are fixedly connected to the lower part of the outer surface of the threaded rod 546. The rotating shaft 545 is fixedly connected to the bevel gear 542 on the same side.

[0038] For further information, see Figure 4 In this embodiment, the motor 541 is fixedly connected to the bottom wall of the inner surface of the housing 6, the connecting ring 543 is fixedly connected to the right end of the filter plate 52 on the same side, the cleaning stick 544 at the bottom is rotatably connected to the lower end of the cleaning device 5, the cleaning stick 544 at the top is rotatably connected to the upper end of the cleaning device 5, the cleaning stick 544 at the bottom and the rotating shaft 545 and the cleaning stick 544 at the top are connected together through two pulleys and a transmission belt, and the two cleaning sticks 544 are rotatably connected to the housing 6;

[0039] It can be seen that when the motor 541 is started, the motor 541 drives the threaded rod 546 to start rotating, which can drive the threaded rod 546 to start rotating, and can drive the connecting ring 543 to move upward, and at this time, the filter plate 52 can be driven to move upward or downward, so as to switch the two filter plates 52. When the filter plate 52 moves upward, it will drive the filter plate 52 to slide on the inner surface of the slide groove 51 on the same side;

[0040] When the threaded rod 546 is started, under the action of the two bevel gears 542, the rotating shaft 545 starts to rotate, and the cleaning rods 544 on the upper and lower sides start to rotate under the action of the pulley and the transmission belt, and the filter plate 52 moving upward or downward is swept and brushed, thereby completing the replacement and sweeping with only one power source of the motor 541, saving costs and improving work efficiency.

[0041] It should be noted that the specific installation method of the motor 541, the circuit connection method and the control method used in the present invention are all conventional designs, and the present invention will not elaborate on them in detail.

[0042] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
