Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, and more specifically, to a high-efficiency multi-stage waste gas filter. Background Art

[0002] An efficient multi-stage exhaust gas filter is a device used to treat industrial exhaust gas. With the continuous development of industrial production, the problem of exhaust gas emissions has become increasingly serious, causing great pollution to the environment. In order to solve this problem, exhaust gas filtration technology has been widely used.

[0003] The existing exhaust gas filter is composed of a shell, an inspection door, an air inlet, an air outlet, a filter element and a grille. The air inlet and the air outlet are respectively installed on both sides of the shell, the inspection door is installed on the front side of the shell, and the filter element and the grille are both installed inside the shell. Its working principle is as follows: open the inspection door, place activated carbon inside the grille, and then close the inspection door. The gas enters the inside of the shell from the air inlet. When the gas passes through the grille, the activated carbon performs a preliminary filtration on the gas. Then the gas passes through the grille and is filtered for a second time by the filter element. Finally, the filtered gas floats out from the outlet, thereby completing the working process of the exhaust gas filter.

[0004] Then, activated carbon is a consumable and needs to be replaced regularly. The existing method of replacing activated carbon requires opening the inspection door first, then pulling out the grille and replacing the activated carbon. This process is relatively cumbersome. When replacing activated carbon, it is necessary to wait for the inspection door to open, which increases working time. Utility Model Content

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

[0021] See also Figure 1 - Figure 5 As shown, a high-efficiency multi-stage exhaust gas filter includes an air outlet 2 and an air inlet 3 fixedly connected to both sides of a shell 1, the air outlet 2 and the air inlet 3 are both connected to the interior of the shell 1, a grille 4 is provided inside the shell 1, a pair of slide rails 5 are fixedly connected to the bottom end of the inner wall of the shell 1, the bottom ends of the grilles 4 are slidably connected to the pair of slide rails 5, an inspection door 6 is provided on the outside of the shell 1, a transmission rod 7 is fixedly connected to the inside of the inspection door 6, the bottom end of the transmission rod 7 is rotatably connected to the inner wall of the shell 1, the top end of the transmission rod 7 passes through the shell 1 and extends to the outside of the shell 1, and a driving mechanism is provided on the outside of the grille 4, and the driving mechanism is used to move the grille 4 and open the inspection door 6.

[0022] Open the inspection door 6, place activated carbon inside the grille 4, and then close the inspection door 6. The gas enters the interior of the shell from the air inlet 3. When the gas passes through the grille 4, the activated carbon performs a preliminary filtration on the gas. Then, the gas passes through the grille 4 and is filtered twice by the filter element. Finally, the filtered gas floats out from the air outlet 2, thereby completing the working process of the exhaust gas filter. Then, the activated carbon is a consumable and needs to be replaced regularly. The existing replacement of activated carbon requires opening the inspection door 6 first, then pulling out the grille 4, and replacing the activated carbon. This process is relatively cumbersome. When replacing the activated carbon, it is necessary to wait for the inspection door 6 to be opened, which increases the working time and reduces the working efficiency. In order to solve the above problems, when replacing the inside of the grille 4, When the activated carbon is being replaced, it is only necessary to rotate the driving mechanism. When the driving mechanism is running, the inspection door 6 will be opened and the grille 4 will be moved at the same time. It should be noted that there is a certain distance between the grille 4 and the inspection door 6, and the grille 4 is located at the end of the inspection door 6 away from the transmission rod 7. Therefore, when the grille 4 moves, it will not collide with the inspection door 6. Then the activated carbon inside the grille 4 will be replaced. Finally, the inspection door 6 is closed, and the inspection door 6 can be driven by the driving mechanism to move and reset the grille 4. Through the above-mentioned structural design, the driving mechanism can drive the grille 4 and the inspection door 6 to move and open synchronously when it is running, avoiding the problem of having to open the inspection door 6 and move the grille 4 separately to replace the activated carbon, thereby effectively improving the work efficiency.

[0023] like Figure 1 - Figure 5 As shown, the driving mechanism includes a rack 8, which is fixedly connected to the outer side of the grille 4, and a gear 9 is meshed with the rack 8 on the side away from the grille 4. A support rod 10 is fixedly connected to the inside of the gear 9, and the bottom end of the support rod 10 is rotatably connected to a connecting plate 11, and the end of the connecting plate 11 away from the gear 9 is fixedly connected to the top of the inner wall of the shell 1, and the top of the support rod 10 passes through the shell 1 and extends to the outside of the shell 1, and an L-shaped plate 12 is fixedly connected to the end of the grille 4 close to the rack 8, and the end of the L-shaped plate 12 away from the grille 4 is in contact with the inspection door 6.

[0024] by Figure 5When the gear 9 rotates, it will drive the rack 8 to move toward the inspection door 6, and the inspection door 6 moves and drives the grille 4 to move. At the moment the grille 4 moves, the grille 4 will squeeze the inspection door 6 through the L-shaped plate 12. Since there is a certain distance between the grille 4 and the inspection door 6, when the L-shaped plate 12 squeezes the inspection door 6, the grille 4 has not reached the initial position of the inspection door 6. With the squeezing of the L-shaped plate 12, the inspection door 6 will drive the transmission rod 7 to rotate and thus open. At this time, when the grille 4 moves out of the shell 1, it will not collide with the inspection door 6. Then, the activated carbon inside the grille 4 is replaced, and then the inspection door 6 is closed. At this time, the inspection door 6 reversely squeezes the L-shaped plate 12, and the force on the L-shaped plate 12 will drive the grille 4 to move and reset. When the inspection door 6 is completely closed, the grille 4 is just reset to the initial position.

[0025] like Figure 2 and Figure 3 As shown, a coil spring 13 is fixedly connected to the top of the transmission rod 7 , and a fixing block 14 is fixedly connected to one end of the coil spring 13 away from the transmission rod 7 , and a bottom end of the fixing block 14 is fixedly connected to the top of the housing 1 .

[0026] When the inspection door 6 is rotated to open, the inspection door 6 will drive the coil spring 13 to deform through the transmission rod 7. After the inspection door 6 finishes rotating, the pulling force generated by the inspection door 6 on the coil spring 13 through the transmission rod 7 ends, and the coil spring 13 will instantly release its elastic potential energy, and drive the inspection door 6 to reset through the transmission rod 7. It should be noted that the elastic potential energy generated by the coil spring 13 can overcome the friction generated during the movement of the driving mechanism and the weight of the grille 4 itself.

[0027] like Figure 4 and Figure 5 As shown, a turntable 15 is fixedly connected to the top end of the support rod 10 , and a turning handle 16 is rotatably connected to the top end of the turntable 15 .

[0028] In order to facilitate the user to rotate the support rod 10, when rotating the support rod 10, it is only necessary to rotate the handle 16, and the handle 16 will drive the turntable 15 to rotate, and the turntable 15 will drive the support rod 10 at its bottom end to rotate.

[0029] like Figure 4 and Figure 5 As shown, a groove is formed at one end of the L-shaped plate 12 away from the grille 4 , and a roller 17 is rotatably connected to the inner wall of the groove, and the outer side of the roller 17 is in contact with the inspection door 6 .

[0030] In order to reduce the friction between the L-shaped plate 12 and the inspection door 6, a groove is opened at one end of the L-shaped plate 12 close to the inspection door 6, and a roller 17 is installed inside the groove. In this way, when the L-shaped plate 12 and the inspection door 6 are in contact, the roller 17 will rotate along the inspection door 6, thereby effectively reducing the friction and increasing the service life of the device.

[0031] Working principle: open the inspection door 6, place activated carbon inside the grille 4, then close the inspection door 6, the gas enters the interior of the shell from the air inlet 3, when the gas passes through the grille 4, the activated carbon performs preliminary filtration on the gas, then the gas passes through the grille 4 and is filtered twice by the filter element, finally, the filtered gas floats out from the air outlet 2, thus completing the working process of the exhaust gas filter, then, the activated carbon is a consumable, it needs to be replaced regularly, and the existing replacement of activated carbon requires opening the inspection door 6 first, then pulling out the grille 4, and replacing the activated carbon, the process is relatively cumbersome, when replacing the activated carbon, it is necessary to wait for the inspection door 6 to be opened, which increases the working time and reduces the working efficiency. In order to solve the above problems, when replacing the grille 4 When the activated carbon inside is replaced, it is only necessary to rotate the driving mechanism. When the driving mechanism is running, the inspection door 6 will be opened and the grille 4 will be moved at the same time. It should be noted that there is a certain distance between the grille 4 and the inspection door 6, and the grille 4 is located at the end of the inspection door 6 away from the transmission rod 7. Therefore, when the grille 4 moves, it will not collide with the inspection door 6. Then, the activated carbon inside the grille 4 is replaced. Finally, the inspection door 6 is closed, and the inspection door 6 can be driven by the driving mechanism to move and reset the grille 4. Through the above-mentioned structural design, the driving mechanism can drive the grille 4 and the inspection door 6 to move and open synchronously when it is running, avoiding the problem of having to open the inspection door 6 and move the grille 4 separately to replace the activated carbon, effectively improving the work efficiency. Figure 5When the gear 9 rotates, it will drive the rack 8 to move toward the inspection door 6, and the inspection door 6 moves and drives the grille 4 to move. At the moment the grille 4 moves, the grille 4 will squeeze the inspection door 6 through the L-shaped plate 12. Since there is a certain distance between the grille 4 and the inspection door 6, when the L-shaped plate 12 squeezes the inspection door 6, the grille 4 has not reached the initial position of the inspection door 6. With the squeezing of the L-shaped plate 12, the inspection door 6 will drive the transmission rod 7 to rotate and open. At this time, when the grille 4 moves out of the shell 1, it will not collide with the inspection door 6. Then, the activated carbon inside the grille 4 is replaced, and the inspection door 6 is closed. At this time, the inspection door 6 reversely squeezes the L-shaped plate 12, and the force on the L-shaped plate 12 will drive the grille 4 to move and reset. When the inspection door 6 is completely closed, the grille 4 is just reset to the initial position. When the inspection door 6 rotates to open, the inspection door 6 The door 6 will drive the coil spring 13 to deform through the transmission rod 7. After the inspection door 6 is rotated, the tension generated by the inspection door 6 on the coil spring 13 through the transmission rod 7 ends, and the coil spring 13 will instantly release its elastic potential energy, and drive the inspection door 6 to reset through the transmission rod 7. It should be noted that the elastic potential energy generated by the coil spring 13 can overcome the friction generated during the movement of the driving mechanism and the weight of the grille 4 itself. In order to facilitate the user to rotate the support rod 10, when rotating the support rod 10, it is only necessary to rotate the handle 16, and the handle 16 will then drive the turntable 15 to rotate, and the turntable 15 will drive the support rod 10 at its bottom end to rotate. In order to reduce the friction between the L-shaped plate 12 and the inspection door 6, a groove is opened at one end of the L-shaped plate 12 close to the inspection door 6, and a roller 17 is installed inside the groove. In this way, when the L-shaped plate 12 contacts the inspection door 6, the roller 17 will rotate along the inspection door 6, thereby effectively reducing the friction and increasing the service life of the device.

Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
