[0025] The purification component 4 is installed on the tank body 1 for purifying the exhaust gas. The purification component 4 includes a water pump 41, a connecting pipe 42 and a spray pipe 43. The water pump 41 is a water pump 41 commonly used in the prior art and applicable to the present embodiment. The water pump 41 is fixed and connected to the side wall of the tank body 1 near the bottom. The spray pipe 43 is fixed and connected to the water outlet of the water pump 41. One end of the spray pipe 43 away from the water pump 41 passes through the side wall of the tank body 1 and extends into the tank body 1. The spray pipe 43 is fixed and connected to the bottom of the connecting pipe 42, and a plurality of spray pipes 43 are provided.

[0026] The mounting frame 5 is slidably connected to the inner wall of the mounting groove 101, and the mounting frame 5 is provided with multiple mounting grooves 101, which correspond one to one with the multiple mounting grooves 101. The filter screen 6 is arranged on the inner wall of the mounting frame 5, and the filter screen 6 is arranged with multiple mounting frames 5. The fixing block 7 is a rectangular parallelepiped structure, and the fixing block 7 is arranged on the side walls of the multiple mounting frames 5. The fixing block 7 cooperates with the fixing groove 102, and the upper surface and the lower surface of the fixing block 7 are both provided with a sliding groove 701 that cooperates with the limiting groove 103, and the side wall of the fixing block 7 is provided with a driving groove 702.

[0027] The limiting assembly 8 is installed on the fixed block 7 and is used to limit the fixed block 7. The limiting assembly 8 includes a double-headed screw 801 and a limiting block 802. The double-headed screw 801 is a vertically arranged rod-shaped structure. The double-headed screw 801 is arranged on the fixed block 7 and is rotatably connected. The double-headed screw 801 is provided with two sections of threads with equal pitch and opposite rotation direction, and the two sections of threads are respectively arranged in the two slide grooves 701. The limiting block 802 is a rectangular parallelepiped structure. The limiting block 802 is sleeved on the double-headed screw 801 and is threadedly connected. There are two limiting blocks 802 and they are plugged and matched with the two limiting grooves 103. The two limiting blocks 802 are respectively slidably connected with the inner walls of the two slide grooves 701, and the two limiting blocks 802 are respectively arranged on the two sections of threads of the double-headed screw 801.

[0028] The driving assembly 9 is mounted on the fixed block 7 and is used to drive the double-headed screw 801 to rotate. The driving assembly 9 includes a rotating shaft 901, a driving gear 902 and a driven gear 903. The rotating shaft 901 is a vertically arranged round rod-shaped structure, and the rotating shaft 901 is rotatably connected to the inner wall of the driving groove 702. The driving gear 902 is fixedly sleeved on the rotating shaft 901, and the axis of the driving gear 902 coincides with the axis of the rotating shaft 901. The driven gear 903 is fixedly sleeved on the double-headed screw 801, and the driven gear 903 is meshed with the driving gear 902, and the axis of the driven gear 903 coincides with the axis of the double-headed screw 801.

[0029] The two limit blocks 802 are inserted into the two limit grooves 103, and the fixing block 7 is fixed in the fixing groove 102, so that the installation frame 5 and the filter screen 6 are installed in the installation groove 101. The acid mist enters the tank body 1 through the air inlet pipe 2, and the water pump 41 pumps the purified liquid in the tank body 1 into the connecting pipe 42 and sprays and purifies the acid mist through the spray pipe 43, and then it is filtered by the multi-layer filter screen 6 and discharged through the air outlet pipe 3. When the filter screen 6 needs to be taken out, the staff only needs to turn the driving gear 902 so that the driven gear 903 meshing with the driving gear 902 and the driven gear 903 meshing with the driven gear 903 are meshed with the driven gear 903. 03 The fixed double-headed screw 801 rotates. Since the two limit blocks 802 are threadedly connected to the two sections of threads on the double-headed screw 801, the two limit blocks 802 are slidably connected to the inner walls of the two slide grooves 701. Therefore, the two limit blocks 802 move closer to each other, thereby disengaging from the limit groove 103 and entering the slide groove 701, releasing the limiting effect on the fixed block 7, and then pulling the fixed block 7 to remove the multiple installation frames 5 and the filter 6 from the installation groove 101, so as to facilitate timely cleaning or replacement of the filter 6, thereby reducing the probability of the filtering effect of the filter 6 being reduced due to long-term use.

[0030] In order to facilitate the removal of the installation frame 5 from the fixed block 7, a plug-in block 10 is fixed to the side wall of the installation frame 5 close to the fixed block 7, and a plug-in groove 703 is formed on the side wall of the fixed block 7 for plugging with the plug-in block 10. The cross-section of the plug-in groove 703 and the cross-section of the plug-in block 10 are both dovetail-shaped. The plug-in block 10 is plugged into the plug-in groove 703, so that the installation frame 5 and the fixed block 7 are detachably connected, thereby facilitating the removal of the installation frame 5 from the fixed block 7 for cleaning or replacement. The dovetail-shaped plug-in block 10 and the plug-in groove 703 prevent the installation frame 5 from detaching from the fixed block 7 in the horizontal direction, thereby enhancing the stability between the installation frame 5 and the fixed block 7.

[0031] In order to reduce the probability of acid mist leaking through the fixed groove 102, a rubber sheet 11 is fixed to the side wall of the fixed block 7 close to the mounting frame 5. The rubber sheet 11 is made of rubber material with good sealing performance. The fixed block 7 cooperates with the fixed groove 102 and presses against the rubber sheet 11, thereby enhancing the sealing of the fixed block 7 to the fixed groove 102, thereby reducing the probability of acid mist leaking through the fixed groove 102.

[0032] In order to prevent the limit block 802 from disengaging from the limit groove 103, a movable groove 704 is opened on the inner wall of the slide groove 701, and a movable block 12 slidingly connected to the movable groove 704 is fixed on the side wall of the limit block 802. The movable block 12 is slidingly connected in the movable groove 704, which limits the moving position of the limit block 802, thereby preventing the limit block 802 from disengaging from the limit groove 103, which is beneficial to the normal use of the limit assembly 8.

[0033] In order to facilitate pulling the fixing block 7 , a handle 13 is fixed to the side wall of the fixing block 7 away from the installation frame 5 . The setting of the handle 13 provides a fulcrum for the fixing block 7 , thereby facilitating the staff to pull the fixing block 7 through the handle 13 .

[0034] Working principle: two limit blocks 802 are inserted into two limit grooves 103, and the fixing block 7 is fixed in the fixing groove 102, so that the installation frame 5 and the filter screen 6 are installed in the installation groove 101. The acid mist enters the tank body 1 through the air inlet pipe 2, and the water pump 41 pumps the purified liquid in the tank body 1 into the connecting pipe 42 and sprays and purifies the acid mist through the spray pipe 43, and then it is filtered by the multi-layer filter screen 6 and discharged through the air outlet pipe 3. When the filter screen 6 needs to be taken out, the staff only needs to turn the driving gear 902 so that the driven gear 903 meshing with the driving gear 902 and the driven gear 903 meshing with the driven gear 903 are meshed with the driven gear 903. The double-headed screw 801 fixed by the gear 903 rotates. Since the two limit blocks 802 are threadedly connected to the two sections of threads on the double-headed screw 801, the two limit blocks 802 are slidingly connected to the inner walls of the two slide grooves 701. Therefore, the two limit blocks 802 move closer to each other, thereby disengaging from the limit groove 103 and entering the slide groove 701, releasing the limiting effect on the fixed block 7, and then pulling the fixed block 7 to remove the multiple installation frames 5 and the filter screen 6 from the installation groove 101, so as to facilitate timely cleaning or replacement of the filter screen 6, thereby reducing the probability of the filtering effect being reduced due to the long-term use of the filter screen 6.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
