Description

Technical Field

[0001] This invention relates to the field of waste gas treatment technology, and in particular to an air filter for indoor waste gas environmental protection treatment. Background Technology

[0002] The needs of production and daily life have led to air pollution in many places. In order to reduce the negative impact of exhaust gas on the living environment, under the current conditions, it is necessary to use air filtration equipment to purify the exhaust gas.

[0003] Although there are various existing air filtration methods, they lack precision requirements. For example, the exhaust gas filter disclosed in CN218280979U has slots on both inner walls of the housing, with a filter frame inserted between the two slots. A filter screen is fixedly installed between the inner walls of the filter frame, and a cleaning plate is slidably connected between the vertical rods. The cleaning plate has bristles on the side near the filter screen, which solves the problem of the cumbersome process of cleaning the filter screen in existing exhaust gas filters. However, for exhaust gases with complex compositions, a single filter screen structure is difficult to effectively filter them. In particular, a fixed filter screen structure is difficult to filter different impurities mixed in with the exhaust gas. Moreover, a static filter screen can only passively filter and purify the exhaust gas, which is not only inefficient but also prone to clogging of the filter screen pores as the filtration cycle lengthens. Even with regular cleaning, the filtration efficiency will decrease, and convenient replacement is difficult. Summary of the Invention

A driven wedge block corresponding to the pressure-boosting boss is integrally connected to the sealing element.

[0010] Preferably, the booster boss is wider at the top and narrower at the bottom, and the driven wedge block slides against the booster boss.

[0011] Preferably, the activated carbon filtration mechanism includes a rotating frame rotatably installed in the lower cavity, an activated carbon filter element is disposed in the rotating frame, and a locking component for fixing the activated carbon filter element is disposed on one side of the rotating frame.

Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] Reference Figures 1-7 An air filter for indoor exhaust gas treatment includes a body 1 with an upper chamber 12 and a lower chamber 13. The body 1 also includes a casing 11. The side wall of the casing 11 has operation windows that connect to the upper chamber 12 and the lower chamber 13 respectively. The casing 11 has a cabinet structure. An upper housing 14 is fixedly installed inside the upper chamber 12. An air inlet 16 extending outside the casing 11 and used for absorbing exhaust gas is integrally connected to the top of the upper housing 14. An air supply pipe 17 extending into the lower chamber 13 is integrally connected to the bottom of the upper housing 14. A lower housing 15, which is fixedly connected to the air supply pipe 17, is fixedly installed inside the lower chamber 13. The bottom of the lower housing 15... The end is integrally connected to an exhaust port 18 extending outside the chassis 11. The air inlet 16 adopts a hollow pipe structure with a T-shaped cross section and circumferentially evenly distributed air inlet holes at the top to absorb the exhaust gas to be purified from multiple angles. By setting the air inlet 16, upper box 14, air supply pipe 17, lower box 15 and exhaust port 18 in sequence inside the chassis 11, the exhaust gas flows through the above positions in sequence and is purified twice by the upper box 14 and the lower box 15 respectively. The exhaust gas becomes purified gas after the initial purification by the upper box 14, and the purified gas becomes clean gas after further purification by the lower box 15.

[0030] The main body 1 is equipped with a molecular sieve filter mechanism 2 through the upper cavity 12 to initially filter the exhaust gas and obtain purified gas. Further, the molecular sieve filter mechanism 2 includes a load-bearing bracket 21 fixedly installed in the upper end of the upper housing 14. A ball screw 22 extending to the outside of the air inlet 16 is rotatably mounted on the load-bearing bracket 21. A sealed bearing for rotatably supporting the ball screw 22 is provided in the air inlet 16 to ensure the airtightness of the air inlet 16 and prevent exhaust gas from escaping through the gap between the two. A lifting nut 23 is fitted on the ball screw 22. A lifting frame 24 that slides through the load-bearing bracket 21 is integrally connected to the lifting nut 23. A pressure-boosting boss 25 is fixedly installed on the lifting frame 24. It should be noted that the lifting nut 23 is guided by the load-bearing bracket 21 to move. Driven by the ball screw 22, the device moves vertically up and down. A molecular sieve plate 26 is fixedly installed inside the lower end of the upper housing 14. The molecular sieve plate 26 has a connected linear sieve hole 27 and a receiving cavity 28. An elastic support member 29 is fixedly installed in the linear sieve hole 27. A sealing member 210 is fixedly connected to the elastic support member 29 and is slidably fitted in the linear sieve hole 27 and the receiving cavity 28. A driven wedge block 211 in the corresponding pressure boosting boss 25 is integrally connected to the sealing member 210. It should be noted that by controlling the linear reciprocating extension and retraction of the sealing member 210 in the linear sieve hole 27 and the receiving cavity 28, the opening size of the linear sieve hole 27 can be adjusted according to the actual needs of waste gas filtration to ensure that the waste gas impurities to be filtered are easily intercepted, thereby performing preliminary filtration and purification of the waste gas.

[0031] The lower chamber 1 is equipped with an activated carbon filter mechanism 3 for further filtering and purifying the gas to obtain clean gas. The activated carbon filter mechanism 3 includes a rotating frame 31 rotatably installed in the lower chamber 13, an activated carbon filter element 32 is disposed in the rotating frame 31, and a locking component 33 for fixing the activated carbon filter element 32 is provided on one side of the rotating frame 31. A drive motor is provided at the bottom of the housing 11 to drive the rotating frame 31 to rotate horizontally. Under the action of the drive motor, the rotating frame 31 drives the activated carbon filter element 32 to rotate, so that the activated carbon filter element 32 can fully contact the purified gas during the rotation, so as to actively filter the purified gas passing through the lower housing 15. The activated carbon filter element 32 adsorbs the micro-impurities mixed in the purified gas. Furthermore, the locking component 33 includes a component opened in the rotating frame 31. A guide elongated hole 331 is located on one side, and an extension frame 332 is connected to the middle of the guide elongated hole 331. A three-way cavity 333 is opened in the extension frame 332. A drive shaft 334 is rotatably installed in the middle of the three-way cavity 333, and a driven shaft 335 driven by the drive shaft 334 is rotatably installed at the upper and lower ends of the three-way cavity 333. A traction roller 338 is integrally connected to the driven shaft 335. A lifting slider 339, which is movably pulled by the traction roller 338, is slidably fitted in the guide elongated hole 331. A limiting clamp 3310, which is movably pulled by the lifting slider 339 and is used to abut against one side of the activated carbon filter element 32, is rotatably installed in the guide elongated hole 331. The limiting clamp 3310 is used to abut against and limit the activated carbon filter element 32 fitted in the rotating frame 31. When the activated carbon filter element 32 needs to be replaced, it is only necessary to control the deflection adjustment of the limiting clamp 3310.

[0032] The upper housing 14 is composed of two semi-cylindrical boxes connected by threads, so as to facilitate the independent installation of the pressure boosting boss 25 and the molecular sieve plate 26.

[0033] The booster boss 25 is wider at the top and narrower at the bottom, and the driven wedge 211 slides against the booster boss 25.

[0034] Driven shaft 334 and driven shaft 335 are respectively keyed with meshing drive bevel gear 336 and driven bevel gear 337. Under the transmission drive of drive bevel gear 336 and driven bevel gear 337, the two driven shafts 335 rotate synchronously, thereby driving the two lifting sliders 339 to move in opposite directions.

[0035] Please refer to the instruction manual for details. Figure 7The traction roller 338 has an annular traction groove 3381. The lower end of the lifting slider 339 is integrally connected to a first traction bolt 3391 that is slidably fitted in the annular traction groove 3381. The upper end of the lifting slider 339 is integrally connected to a second traction bolt 3392. The limiting clamp 3310 has a traction elongated hole 33101 for slidingly fitting the second traction bolt 3392. The lifting slider 339, which moves up and down, is deflected by the limiting clamp 3310 through the second traction bolt 3392.

[0036] It should be noted that the specific model and specifications of the molecular sieve plate 26 and the activated carbon filter element 32 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated here.

[0037] The functional principle of this invention can be explained through the following operational methods:

[0038] Controlling the rotation of the ball screw 22 causes the lifting nut 23 to rise and fall vertically, which in turn drives the pressure boosting boss 25 to rise and fall vertically along the load-bearing bracket 21 to apply pressure to the driven wedge block 211, causing the elastic support 29 to extend and retract horizontally, thereby allowing the sealing element 210 to move and retract within the linear screen hole 27 and the receiving cavity 28 until the linear screen hole 27 is adjusted to the appropriate size.

[0039] An activated carbon filter element 32 is installed in a rotating frame 31. The drive shaft 334 is then rotated, which in turn drives the driven shaft 335 to rotate. The traction roller 338 drives the lifting slider 339 to rise and fall vertically through the annular traction groove 3381. The lifting slider 339 drives the limiting clamp 3310 to deflect through the second traction bolt 3392, so as to limit the activated carbon filter element 32 to abut and limit it on one side of the rotating frame 31.

[0040] Waste gas is introduced into the upper housing 14 through the air inlet 16. The waste gas is initially purified by the molecular sieve plate 26 inside the upper housing 14, so that the purified gas enters the lower housing 15 and is filtered again by the activated carbon filter 32. The clean gas obtained is discharged from the housing 11 through the exhaust port 18.

[0041] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
