DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] In the embodiment of the present invention, please refer to Figures 1 to 6 , an environmentally friendly filter box for VOCs waste gas treatment, comprising an air inlet pipe 1, the air inlet pipe 1 is connected to one end of a fixed folding rod 2, the fixed folding rod 2 is connected to a connecting tube 3, the interior of the connecting tube 3 is divided into a plurality of cavities, the center of the connecting tube 3 is cylindrical, and further comprising: The sealing plate 4 is threadedly connected to the bottom of the connecting tube 3; The filter cartridge 8 is placed inside the connecting cartridge 3, the bottom of the filter cartridge 8 abuts against the sealing plate 4, and the top abuts against the top of the connecting cartridge 3, and the filter cartridge 8 is provided with a plurality of groups; The connecting tube 5 is provided in a plurality of groups, and one end of the connecting tube 5 is connected to the inner cavity of the connecting tube 3; The ring frame 6 is connected to the other end of the connecting pipe 5 and communicated with the interior thereof; An air outlet pipe 7 is connected to the interior of the ring frame 6; The filter replacement mechanism 9 has one end connected to the air intake pipe 1 and the other end connected to the connecting tube 3. The filter replacement mechanism 9 includes: The rotating disk 91 is disposed between the air inlet pipe 1 and the connecting tube 3 and is rotatably connected to the two. An air hole 10 is provided at an eccentric position of the rotating disk 91, and the position of the air hole 10 matches the position of the filter tube 8; A power assembly 92, one end of which is connected to the filter cartridge 8, and the other end of which is connected to the rotating disk 91, for driving the rotating disk 91 to rotate; The limiting component 93 has one end connected to the air intake pipe 1 and the other end connected to the power component 92 , and is used to limit the rotation direction of the rotating disk 91 .

[0022] VOCs waste gas enters the interior of the air inlet pipe 1, and then enters the interior of the filter cartridge 8 through the air hole 10. The filter cartridge 8 filters the VOCs waste gas, and the filtered waste gas flows out through the connecting pipe 5, the ring frame 6 and the air outlet pipe 7 for subsequent treatment. As the filtration proceeds, the filter cartridge 8 is gradually blocked by impurities, and the filtration efficiency decreases, causing the air pressure inside the air inlet pipe 1 to increase. At this time, the power component 92 drives the rotating disk 91 to rotate a certain angle, so that the air hole 10 on the rotating disk 91 rotates to the top of another group of filter cartridges 8, and the waste gas is filtered through another group of clean filter cartridges 8. The limiting component 93 ensures that the rotating disk 91 can only rotate in one direction.

[0023] As an embodiment of the present invention, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 6 , the power assembly 92 comprises: The pneumatic motion component 921 is disposed in the cylinder at the center of the connecting cylinder 3 and is connected to the connecting cylinder 3; A second fixed folding rod 922, one end of which is connected to the pneumatic motion component 921; The vertical tooth plate 923 is connected to the other end of the second fixed folding rod 922; The gear 924 is rotatably connected to the connecting cylinder 3 and meshes with the vertical tooth plate 923; A transverse tooth plate 925 meshes with the gear 924; The limiting folding rod 926 is connected to the connecting tube 3, and the limiting folding rod 926 passes through the transverse tooth plate 925 and is slidably connected thereto; One end of the fixed angle rotating assembly 927 is connected to the transverse gear plate 925 , and the other end is connected to the rotating disk 91 .

[0024] When a group of filter cartridges 8 are gradually clogged by impurities and the filtering efficiency decreases, the air pressure inside the air intake pipe 1 increases, causing the air pressure motion component 921 to move, and the air pressure motion component 921 drives the fixed folding rod 922 to move downward, and the fixed folding rod 922 drives the vertical tooth plate 923 to move downward, and the vertical tooth plate 923 drives the gear 924 to rotate, and the gear 924 drives the horizontal tooth plate 925 to move laterally along the limiting folding rod 926, and the horizontal tooth plate 925 drives the fixed angle rotating component 927 to move, and the fixed angle rotating component 927 drives the rotating disk 91 to rotate a certain angle, so that the air hole 10 rotates to the top of another group of filter cartridges 8, and the exhaust gas is filtered through another group of clean filter cartridges 8.

[0025] As an embodiment of the present invention, please refer to Figure 2 , Figure 4 and Figure 6 , the pneumatic motion component 921 includes: The fixed cylinder 9211 is arranged in the cylinder at the center of the connecting cylinder 3 and connected to the connecting cylinder 3; The sliding rod 9212 is slidably connected to the fixed cylinder 9211; The piston block 9213 is slidably connected to the inner wall of the central cylinder of the connecting cylinder 3 and is connected to one end of the sliding rod 9212. The piston block 9213 is connected to the second fixed folding rod 922; The elastic member 1 9214 is disposed inside the fixed cylinder 1 9211 , and one end of the elastic member 9214 is connected to the other end of the sliding rod 9212 , and the other end of the elastic member 9214 is connected to the fixed cylinder 1 9211 .

[0026] When a group of filter cartridges 8 is clogged by impurities, its filtering effect decreases, and exhaust gas enters the interior of the intake pipe 1, causing the air pressure inside the intake pipe 1 to increase, and the pressure squeezes the piston block 9213, which drives the sliding rod 9212 to move, and the sliding rod 9212 squeezes the elastic member 1 9214, and the piston block 9213 drives the fixed folding rod 2 922 to move. The setting of the elastic member 1 9214 ensures that the piston block 9213 can return to the original position after the rotating disk 91 rotates a certain angle. In this embodiment, the elastic member 1 9214 is a spring.

[0027] As an embodiment of the present invention, please refer to Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , the fixed angle rotation component 927 includes: A magnetic connection component 9271, one end of which is connected to the cross-tooth plate 925; The sliding sleeve 9272 is connected to the other end of the magnetic connection component 9271; Abutting the sliding rod 9273, and slidably connected with the sliding sleeve 9272; The ratchet gear 9274 is connected to the rotating disk 91 and abuts against one end of the abutting slide bar 9273; The spring piece 9275 is connected to the air inlet pipe 1 and abuts against the other end of the abutting slide bar 9273; The limiting rebound component 9276 has one end connected to the magnetic connection component 9271 and the other end connected to the connection tube 3.

[0028] The transverse tooth plate 925 drives the magnetic connection component 9271 to move, and the magnetic connection component 9271 drives the sliding sleeve 9272 and the limit rebound component 9276 to move laterally. The sliding sleeve 9272 drives the abutting slide bar 9273 to move laterally. At the same time, the spring piece 9275 squeezes the abutting slide bar 9273, so that the abutting slide bar 9273 is always in abutment with the ratchet teeth 9274. When the limit rebound component 9276 moves to the maximum distance, the magnetic connection component 9271 is separated, and the limit rebound component 9276 drives the sliding sleeve 9272 and the abutting slide bar 9273 to move in the opposite direction and return to the original position. The abutting slide bar 9273 drives the rotating disk 91 to rotate through the ratchet teeth 9274, and the rotation angle of the rotating disk 91 is always fixed.

[0029] As an embodiment of the present invention, please refer to Figure 1 , Figure 4 and Figure 6 , the magnetic connection assembly 9271 includes: Magnetic block 1 92711, connected to the cross tooth plate 925; The second magnetic block 92712 is connected to the sliding sleeve 9272 and is magnetically adsorbed to the first magnetic block 92711.

[0030] Magnetic properties of magnet block 1 92711 and magnet block 2 92712 are opposite. In the initial state, the two are attracted together by magnetic force, and the movement of the cross tooth plate 925 drives magnet block 1 92711, magnet block 2 92712 and limit rebound assembly 9276 to move synchronously. When the limit rebound assembly 9276 moves to the maximum distance, the cross tooth plate 925 continues to move, driving magnet block 1 92711 to continue to move, so that magnet block 1 92711 and magnet block 2 92712 are separated, and the limit rebound assembly 9276 rebounds and drives magnet block 2 92712 to move in the opposite direction and return to the original position, so that the rotating disk 91 rotates, and the air hole 10 rotates to above another filter cartridge 8, and the filter cartridge 8 filters the exhaust gas.

[0031] As an embodiment of the present invention, please refer to Figure 1 , Figure 4 and Figure 6 The limit rebound component 9276 includes: One end of the sliding folding rod 92761 is connected to the second magnetic block 92712; The second fixed cylinder 92762 is connected to the connecting cylinder 3 and is slidably connected to the sliding folding rod 92761; The second elastic member 92763 is disposed inside the second fixed cylinder 92762, and one end of the elastic member is connected to the other end of the sliding folding rod 92761, and the other end of the elastic member is connected to the second fixed cylinder 92762; The limiting block 92764 is connected to the sliding folding rod 92761.

[0032] The horizontal tooth plate 925 drives the sliding sleeve 9272 and the sliding folding rod 92761 to move synchronously horizontally through the magnetic block 1 92711 and the magnetic block 2 92712. The sliding folding rod 92761 drives the limit block 92764 to move synchronously. At the same time, the elastic member 2 92763 undergoes elastic deformation. When the limit block 92764 moves to abut against the fixed cylinder 2 92762, the sliding sleeve 9272, the abutting sliding rod 9273 and the magnetic block 2 92712 can no longer move with the fixed cylinder 2 92762. As the horizontal tooth plate 925 moves, the horizontal tooth plate 925 continues to move, so that the first magnetic block 92711 is separated from the second magnetic block 92712. At this time, under the reaction force of the second elastic member 92763, the sliding folding rod 92761 is driven to move in the opposite direction, and the sliding folding rod 92761 drives the sliding sleeve 9272 and the contact sliding rod 9273 to move in the opposite direction. The contact sliding rod 9273 squeezes the ratchet teeth 9274, drives the ratchet teeth 9274 to rotate, and then drives the rotating disk 91 to rotate. In this embodiment, the second elastic member 92763 is a spring.

[0033] As an embodiment of the present invention, please refer to Figure 1 , Figure 4 and Figure 5 , the limiting component 93 includes: A third fixed folding rod 931, one end of which is connected to the air inlet pipe 1; The limiting tooth 932 is rotatably connected to the other end of the fixed folding rod 3 931, and the limiting tooth 932 is engaged with the ratchet tooth 9274; The spiral spring 933 has one end connected to the fixed folding rod 3 931 and the other end connected to the limiting tooth 932 .

[0034] The limiting tooth 932 is engaged with the ratchet tooth 9274 to limit the rotation direction of the rotating disk 91 to prevent the rotating disk 91 from rotating when the abutting slide bar 9273 moves in the opposite direction driven by the elastic member 2 92763, the rotating disk 91 is driven to rotate, and the rotating disk 91 drives the ratchet tooth 9274 to rotate. The ratchet tooth 9274 squeezes the limiting tooth 932, so that the limiting tooth 932 rotates around the fixed folding rod 3 931. The limiting tooth 932 will not affect the rotation of the rotating disk 91, and the spiral spring 933 ensures that the limiting tooth 932 can return to its original position.

[0035] The working principle of the present invention is as follows: VOCs waste gas enters the interior of the air inlet pipe 1, and then enters the interior of the filter cartridge 8 through the air hole 10, the filter cartridge 8 filters the VOCs waste gas, and the filtered waste gas flows out through the connecting pipe 5, the ring frame 6 and the air outlet pipe 7 for subsequent treatment. As the filtering proceeds, the filter cartridge 8 is gradually clogged by impurities, and the filtering efficiency decreases, causing the air pressure inside the air inlet pipe 1 to increase, and the pressure squeezes the piston block 9213, the piston block 9213 drives the sliding rod 9212 to move, the sliding rod 9212 squeezes the elastic member 1 9214, the piston block 9213 drives the fixed folding rod 2 922 to move downward, and the fixed folding rod 2 922 drives the vertical tooth plate 923 moves downward, the vertical tooth plate 923 drives the gear 924 to rotate, the gear 924 drives the horizontal tooth plate 925 to move horizontally along the limit folding rod 926, the horizontal tooth plate 925 drives the sliding sleeve 9272 and the sliding folding rod 92761 to move horizontally synchronously through the magnetic block 1 92711 and the magnetic block 2 92712, the sliding sleeve 9272 drives the abutting slide bar 9273 to move horizontally, and at the same time, the spring piece 9275 squeezes the abutting slide bar 9273, so that the abutting slide bar 9273 always abuts against the ratchet teeth 9274, and the limit teeth 932 are engaged with the ratchet teeth 9274, so as to limit the rotation direction of the rotating disk 91 and prevent the abutting slide bar 9273 from being in the horizontal tooth plate 9 25, the rotating disk 91 is rotated, the sliding folding rod 92761 drives the limit block 92764 to move synchronously, and at the same time, the elastic member 2 92763 is elastically deformed. When the limit block 92764 moves to abut against the fixed cylinder 2 92762, the sliding sleeve 9272, the abutting sliding rod 9273 and the magnetic block 2 92712 can no longer move with the cross tooth plate 925. The cross tooth plate 925 continues to move, so that the magnetic block 1 92711 is separated from the magnetic block 2 92712. At this time, under the reaction force of the elastic member 2 92763, the sliding folding rod 92761 is driven to move in the opposite direction, and the sliding folding rod 92761 drives The sliding sleeve 9272 and the abutting slide bar 9273 move in opposite directions, and the abutting slide bar 9273 squeezes the ratchet teeth 9274, driving the ratchet teeth 9274 to rotate, and then driving the rotating disk 91 to rotate a certain angle, so that the air hole 10 rotates to the top of another group of filter cartridges 8, and the exhaust gas is filtered by another group of clean filter cartridges 8. The air pressure inside the intake pipe 1 is reduced, and under the reaction force of the elastic member 9214, the piston block 9213 moves upward and returns to the original position, and at the same time drives the vertical tooth plate 923, the horizontal tooth plate 925 and the magnetic block 1 92711 back to the original position, and the magnetic block 1 92711 is magnetically connected to the magnetic block 2 92712 again.
