Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of multi-stage filter technology, and more specifically, to a multi-stage filter for treating organic waste gas. Background Technology

[0002] Organic waste gas refers to waste gas containing volatile organic compounds and other organic substances. These waste gases have a wide range of sources and pose certain hazards to the environment and human health. Before these waste gases are discharged, they usually need to be filtered through multiple stages using multi-stage filters to remove toxic impurities before being discharged.

[0003] When filtering exhaust gas, a fan is usually used to draw the exhaust gas into a multi-stage filter, allowing the exhaust gas to pass through multiple components within the filter for graded filtration. However, when filtering exhaust gas with different concentrations, existing filters struggle to control the entry path of the exhaust gas. For example, if the amount of exhaust gas to be filtered is small, the smaller volume of exhaust gas has more space to move within the filter. When the fan adsorbs the exhaust gas, it is more dispersed within the filter, resulting in a longer time for the fan to adsorb the exhaust gas into the next filtration cavity, thus reducing filtration efficiency. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a multi-stage filter for treating organic waste gas, which solves the technical problem in the prior art that when the amount of waste gas to be filtered is small, the movement space of the waste gas relative to the filter is large, and the time for the waste gas to be adsorbed into the next filter is long.

Three lifting assemblies are provided, each disposed at the top of one of the three filter bodies. Three compression boxes are provided, each disposed on one of the three lifting assemblies. Three compression plates are provided, each slidably mounted within one of the three compression boxes. The lifting assembly is used to move the compression boxes and compression plates downwards, thereby reducing the space.

[0006] Furthermore, the air compression assembly includes a mounting plate, a cylinder, and a push rod. There are two mounting plates, which are respectively fixedly installed on both sides of the placement plate.

The transmission assembly is located on the support cover.

[0008] Furthermore, the transmission assembly includes a rotating shaft, a support frame, and a transmission shaft. There are three rotating shafts, which are respectively rotatably mounted on three drive screws, and the three rotating shafts are rotating shaft one, rotating shaft two, and rotating shaft three.

There are two transmission shafts, which are respectively rotatably mounted through the two support frames.

[0009] Furthermore, the transmission assembly also includes a gear ring I, a gear I, a gear ring II, a gear II, and a motor. Two gear rings I are provided, each fixedly mounted on a rotating shaft I and a rotating shaft II, respectively. Two gears I are provided, each fixedly mounted at both ends of one of the transmission shafts, and each gear I meshes with one of the gear rings I. Two gear rings II are provided, each fixedly mounted on a rotating shaft II and a rotating shaft III, respectively.

[0015] The beneficial effects of the embodiments disclosed herein are as follows:

[0016] In this disclosure, when the amount of exhaust gas to be filtered is small, the air compressor can drive the air compressor plate to compress the exhaust gas through the space of the three filter bodies, thereby reducing the space through which the exhaust gas passes and accelerating the passage rate. Furthermore, the lifting assembly can drive the compression plate and compression box to move downward, thereby reducing the height space of the exhaust gas in the filter body, further reducing its movement space and accelerating the movement rate of the exhaust gas. In addition, the transmission assembly can drive the compression plate and compression box in the three filter bodies to move downward synchronously, which also saves the use of motors.

The filter also includes a compression assembly, a compression plate 3, a lifting assembly, a compression box 4, and a compression plate 5. Three compression assemblies are provided, and all three compression assemblies are located on the side of the placement plate 1. The compression assemblies are used to compress the space through which the waste gas passes. Several compression plates 3 are provided, and several compression plates 3 are respectively installed on several compression assemblies. Three lifting assemblies are provided, and three lifting assemblies are respectively installed on the top of the three filter bodies 2. Three compression boxes 4 are provided, and three compression boxes 4 are respectively installed on the three lifting assemblies. Three compression plates 5 are provided, and three compression plates 5 are respectively slidably installed in the three compression boxes 4.

[0030] An air inlet pipe 6 is installed between each of the three filter bodies 2, and a fan 7 is installed on the placement plate 1. One of the air inlet pipes 6 is connected to the fan 7. It should be noted that a filter plate, an activated carbon plate, and cleaning agents are installed in each of the three filter bodies 2. By starting the fan 7, the exhaust gas gradually passes through the three filter bodies 2, thereby gradually filtering and cleaning it.

[0031] The size of the air compressor plate 3 is consistent with the size of the side of the filter body 2. The air compressor plate 3 is located inside the filter body 2, and the push rod 103 is slidably installed through the side of the filter body 2, so as to push the air compressor plates 3 on the two inner sides of the filter body 2 to move relative to each other, thereby compressing the space.

[0032] The side of the air compressor plate 3 is provided with a sliding groove, and the compression plate 5 and the compression box 4 are slidably installed in the sliding groove of the air compressor plate 3. When the compression plate 5 and the compression box 4 are moved down, the compression plate 5 and the compression box 4 can slide in the sliding groove on the side of the air compressor plate 3.

[0033] In some examples, reference Figure 2The air compression assembly includes a mounting plate 101, a cylinder 102, and a push rod 103. There are two mounting plates 101, which are fixedly installed on both sides of the placement plate 1. There are two cylinders 102, which are installed on the sides of the two mounting plates 101. There are two push rods 103, which are fixedly connected to the output ends of the two cylinders 102. The two air compression plates 3 are fixedly connected to the sides of the two push rods 103.

[0034] In some examples, reference Figure 3 and Figure 4 The lifting assembly includes a support cover 201, a drive screw 202, a slide rod 203, a moving block 204, a slider 205, a lifting rod 206, and a transmission assembly. A groove is provided at the top of the filter body 2. Two support covers 201 are provided, each slidably mounted within the groove at the top of the filter body 2. The drive screw 202 is rotatably mounted within one of the support covers 201, and the slide rod 203 is fixedly mounted within the other support cover 201. The moving block 204 is threadedly connected to the drive screw 202, and the slider 205 is slidably mounted on the slide rod 203. Two lifting rods 206 are provided, each fixedly mounted on the side of the moving block 204 and the slider 205, respectively. The bottom ends of the two lifting rods 206 are fixedly connected to the top of the compression box 4. The transmission assembly is mounted on the support cover 201.

[0035] Each of the three filter bodies 2 has two through slots at its top, and two lifting rods 206 pass through the two through slots respectively. The lifting rods 206 pass through the top of the filter body 2 and can connect the compression plate 5 and the compression box 4 inside the filter body 2. The sum of the lengths of the compression box 4 and the compression plate 5 is consistent with the length of the top of the filter body 2, and the sum of the widths of the compression box 4 and the compression plate 5 is consistent with the width of the top of the filter body 2, which can ensure that the exhaust gas will not escape from other gaps.

[0036] In some examples, reference Figure 3 and Figure 4 The transmission assembly includes a rotating shaft, a support frame 302, and a transmission shaft 303. There are three rotating shafts, which are rotatably mounted on three drive screws 202 respectively. The three rotating shafts are rotating shaft one 401, rotating shaft two 402, and rotating shaft three 403. There are two support frames 302, which are fixedly mounted on the top of two support covers 201 respectively. There are two transmission shafts 303, which are rotatably mounted through two support frames 302 respectively.

[0037] In some examples, reference Figure 3 and Figure 4The transmission assembly also includes a gear ring 304, a gear 305, a gear ring 306, a gear 307, and a motor 308. Two gear rings 304 are provided, each fixedly mounted on a rotating shaft 401 and a rotating shaft 402, respectively. Two gears 305 are provided, each fixedly mounted at both ends of one of the transmission shafts 303, and each gear meshes with one of the gear rings 304. Two gear rings 306 are provided, each fixedly mounted on a rotating shaft 402 and a rotating shaft 403, respectively. Two gears 307 are provided, each fixedly mounted at both ends of another transmission shaft 303, and each gear meshes with one of the gear rings 306. The motor 308 is mounted on the side of one of the support covers 201, and the output end of the motor 308 is fixedly connected to the top end of the rotating shaft 402.

[0038] Working principle: When the amount of exhaust gas to be purified is small, cylinder 102 is started first. The output end of cylinder 102 drives the push rod 103 to slide on the side of the filter body 2. At the same time, when the two pressure plates 3 move relative to each other, they can push the compression plate 5 to slide in the compression box 4, thereby sliding the compression plate 5 into the compression box 4. At this time, the exhaust gas is reduced in size after passing through the internal space of the filter body 2. Then, motor 308 is started. The output end of motor 308 drives the rotating shaft 402 to rotate. The rotating shaft 402 drives the gear ring 304 and gear ring 306 to rotate. The gear ring 304 and gear ring 306 respectively drive the gear 305 and gear 307 meshing with them to rotate. 307 drives two drive shafts 303 to rotate. The two drive shafts 303 respectively drive gear one 305 and gear two 307 at their other ends to rotate. Gear one 305 and gear two 307 drive the gear rings one 304 and gear ring two 306 on rotating shaft one 401 and rotating shaft three 403 to mesh with them, thereby causing the three drive screws 202 to rotate simultaneously, driving the moving block 204 to move up and down. The moving block 204 drives the lifting rod 206 to move up and down. The lifting rod 206 drives the compression box 4 to move down. And another lifting rod 206, driven by the compression box 4, causes the slider 205 to move up and down synchronously on the sliding rod 203, thereby causing the compression box 4 and the compression plate 5 to move down, further reducing the internal space of the filter body 2.

[0039] When the fan 7 is started, it absorbs the exhaust gas. Because the space for the exhaust gas to move is reduced, the exhaust gas passes through the fan 7 at a faster speed. It is then filtered step by step through the three filter bodies 2 before being released.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
