Description

Technical Field

[0001] This utility model relates to the field of gas purification technology for C4 equipment, and more specifically, to a gas purification and filtration device for C4 equipment. Background Technology

[0002] Existing C4 equipment, such as vehicle-mounted air circulation systems and gas purification and filtration devices in industrial gas processing units, suffers from problems such as insufficient filtration efficiency, high maintenance costs, weak self-cleaning capabilities, and unreasonable structural design.

[0003] Traditional single-stage filters struggle to effectively intercept large particles while filtering fine impurities, leading to frequent clogging, rapid degradation of purification efficiency, and the need for manual disassembly and cleaning, which is cumbersome and environmentally polluting. Maintenance is particularly difficult in confined spaces like vehicles, as the lack of an active cleaning mechanism allows impurities to accumulate, increasing pressure drop and impacting equipment stability and energy efficiency. Furthermore, the absence of coordinated cleaning between multi-stage filtration layers means that impurities in the upper layers can easily contaminate the lower high-precision filter elements, shortening the overall lifespan. Utility Model Content

[0004] The purpose of this invention is to provide a gas purification and filtration device for C4 equipment. It features multi-stage filtration for coordinated purification, with a pre-treatment screen intercepting large particles such as hair and debris to prevent clogging of the main filter element. The first and second filter screens achieve medium and high precision filtration, respectively, thereby improving gas filtration efficiency. The three-stage gradient filtration extends the filter element's lifespan and solves the problems of manual disassembly and cleaning of filter screens, which are cumbersome, pollute the environment, and are difficult to maintain, especially in compact spaces such as vehicles.

[0005] To achieve the above objectives, a gas purification and filtration device for C4 equipment is provided, including the body of the C4 equipment. A slot is provided on the back of the body, and a filter chamber is provided in the inner cavity of the slot. A rear cover is snapped onto the top of the slot. The slot and filter chamber are integrated into a single design, saving internal space of the C4 equipment (such as a vehicle center console) and adapting to compact scenarios.

[0006] It also includes: a pull plate, which is located inside the filter chamber. A pretreatment screen is fixedly connected to the middle of the pull plate. The pretreatment screen has large filter holes to intercept large particles in the gas and prevent the filter equipment from clogging. The pull plate can be pulled to move it to the outside of the filter chamber, making it easy to clean the pretreatment screen and avoid the accumulation of large particles. A scraper is fixedly connected to the bottom of the pull plate. The scraper extends to the next layer of filter device. Pulling the pull plate again allows the scraper to remove the dust accumulated on the next layer of filter device.

[0007] The pretreatment screen intercepts large particles (such as hair and debris) to prevent the main filter from clogging and extend its overall service life. When the pull plate is pulled, the scraper simultaneously removes impurities from the lower filter screen, reducing the frequency of manual maintenance.

[0008] As a further improvement to this technical solution, an air inlet pipe is connected to the empty slot, one end of which is connected to the filter chamber. An air outlet pipe is connected to the bottom of the filter chamber, one end of which passes through the empty slot and extends to the outside of the machine body. The top of the filter chamber can be opened. A pull plate is fixedly connected to the top of the pull plate, and the pull plate passes through the top of the filter chamber. Two sets of partitions are fixedly connected to the inner cavity of the filter chamber. The two sides of the pull plate are in contact with the two sets of partitions. Slide plates are fixedly connected to both sides of the pull plate, and the slide plates pass through the partitions. A slide rail is fixedly connected to the side wall of the filter chamber, and the slide rail is slidably connected to the slide plate.

[0009] The intake and exhaust pipes are arranged diagonally to create a "top-in, bottom-out" vortex effect, which enhances the uniformity of filtration. The piping is integrated into the back of the unit, reducing the space occupied by external pipes and adapting to the limited installation space of vehicle or industrial equipment.

[0010] The top-opening design allows for one-handed operation, enabling cleaning of the pretreatment screen without disassembling the entire device. The sliding plate and rail work together to ensure smooth movement of the pull plate, preventing the filter screen from shifting and causing a decrease in sealing.

[0011] Both sides of the slide plate are fixedly connected to baffles, and a return spring is fixedly connected between the bottom of the baffle and the bottom of the filter chamber.

[0012] The return spring pushes the pull plate to automatically reset, avoiding manual alignment and improving ease of use. The baffle limits the slide travel to prevent the pull plate from completely detaching from the filter chamber, ensuring structural safety.

[0013] As a further improvement to this technical solution, a first mounting plate is fixedly connected between the two sets of partitions and on one side of the pull plate. A first filter screen is fixedly connected to the middle of the first mounting plate. The filter holes of the first filter screen are smaller than those of the pre-treatment screen, and the filtration accuracy is higher than that of the pre-treatment screen. A second mounting plate is fixedly connected between the two sets of partitions and on one side of the first mounting plate. A second filter screen is fixedly connected to the middle of the second mounting plate. The filter holes of the second filter screen are smaller than those of the first filter screen, and the filtration accuracy is higher than that of the first filter screen.

[0014] The treatment screen (large particle interception) + the first filter screen (medium particle filtration) form a two-stage protection, reducing the burden on the main filter element. The multi-stage filtration disperses the impurity load, slows down the rate of increase in filter screen pressure drop, and extends the maintenance cycle.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This gas purification and filtration device for C4 equipment features multi-stage filtration for coordinated purification. The pretreatment screen intercepts large particles such as hair and debris, preventing clogging of the main filter element. The first and second filter screens achieve medium and high precision filtration, respectively, improving gas filtration efficiency. The three-stage gradient filtration extends the filter element's lifespan.

[0017] 2. The gas purification and filtration device of this C4 equipment features dynamic self-cleaning and convenient maintenance. The pull plate can be pulled out to the outside of the filter chamber to directly clean the pretreatment screen. The scraper removes impurities from the surface of the lower filter screen as it moves with the pull plate, reducing manual intervention.

[0018] 3. The gas purification and filtration device of this C4 equipment has a compact structure and improved reliability. The sliding plate and slide rail work together to ensure smooth sliding of the pull plate. The return spring automatically returns to its original position to avoid jamming. The filter chamber is integrated with the hollow groove on the back of the body, saving space and making it suitable for vehicle-mounted or small equipment. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] Please see Figures 1-4 As shown, the purpose of this embodiment is to provide a gas purification and filtration device for C4 equipment. The slot 18 is opened on the back of the body 1, and the two are integrally formed. This connection method makes the structure of the entire device more compact, makes reasonable use of the space on the back of the body 1, and provides a space basis for the installation of subsequent components such as the filter chamber 3. It is suitable for C4 equipment with limited space, such as vehicle environment.

[0029] Please see Figure 2 As shown, the filter chamber 3 is installed in the empty slot 18. The two fit together tightly, and the filter chamber 3 can be stably placed in the body 1, ensuring the stability of the entire filtration device. At the same time, it also makes the appearance of the device more regular. The back cover 2 is snapped onto the top of the filter chamber 3. This snap-fit ​​connection method makes it easy to open and close the filter chamber 3, and facilitates the cleaning and maintenance of the components inside the filter chamber 3, such as cleaning the pretreatment screen 7.

[0030] Please see Figures 2-3 As shown, the air inlet pipe 4 is connected to the empty slot 18, and then to the filter chamber 3. This connection allows the gas to be filtered to enter the filter chamber 3 smoothly. The "upward" layout helps to form a good airflow channel and improve the efficiency of gas entry.

[0031] Please see Figures 2-3 As shown, the exhaust pipe 5 passes through the body 1 and is connected to the filter chamber 3, realizing the function of the filtered gas being discharged from the filter chamber 3 to the body 1. The "bottom-out" layout forms a diagonal design with the intake pipe 4, which can create a vortex effect, enhance the uniformity of filtration, and improve the filtration effect.

[0032] Please see Figure 4 As shown, the pretreatment screen 7 is fixed in the middle of the pull plate 6, and the two are fixedly connected. When the pull plate 6 moves, the pretreatment screen 7 can move along with it, making it easy to pull the pretreatment screen 7 out of the filter chamber 3 for cleaning, intercepting large particles of impurities while facilitating maintenance.

[0033] Please see Figures 2-3 As shown, the pull plate 19 is connected to the pull plate 6 and exposed in the filter chamber 3. By pulling the pull plate 19, the movement of the pull plate 6 can be easily operated, providing a convenient way to clean the pretreatment screen 7.

[0034] Please see Figure 3 As shown, the two sides of the pull plate 6 are connected to the slide plate 12. The slide plate 12 moves synchronously with the pull plate 6. The slide plate 12 provides support and guidance for the movement of the pull plate 6, ensuring the smoothness of the movement of the pull plate 6.

[0035] Please see Figures 2-3 As shown, the slide plate 12 is mounted on the slide rail 13, and the two are slidably connected. The slide rail 13 is fixed on the partition 17. This connection method allows the pull plate 6 to slide smoothly along the slide rail 13, avoiding the pull plate 6 from shifting or getting stuck during movement.

[0036] Please see Figures 2-3 As shown, baffles 14 are installed on both sides of the slide plate 12 and are an integral part of the slide plate 12. The baffles 14 can limit the sliding stroke of the slide plate 12 and prevent the pull plate 6 from completely detaching from the filter chamber 3, thus ensuring the safety and stability of the structure.

[0037] Please see Figure 4 As shown, the reset spring 15 is connected between the bottom of the baffle 14 and the filter chamber 3. When the pull plate 6 is pulled and the pull plate 19 is released, the reset spring 15 can use its own elasticity to make the pull plate 6 automatically reset, avoiding manual alignment operation and improving the convenience of use.

[0038] Please see Figure 4 As shown, the scraper 16 is fixed to the bottom of the pull plate 6 and extends to the lower filter device. When the pull plate 6 moves, the scraper 16 can move synchronously to scrape off impurities on the surface of the lower filter screen, reducing the frequency of manual cleaning of the lower filter screen and improving the self-cleaning ability of the entire filter device.

[0039] Please see Figure 4 As shown, the first filter screen 9 is fixed on the first mounting plate 8, and the two are fixedly connected. The first mounting plate 8 provides installation and support for the first filter screen 9, ensuring the stability of the first filter screen 9 in the filter chamber 3. Its filter holes are smaller than those of the pretreatment screen 7, which can further filter the pretreated gas.

[0040] Please see Figure 4 As shown, the second filter screen 11 is fixed on the second mounting plate 10, and the two are fixedly connected. The second mounting plate 10 provides installation and support for the second filter screen 11. Its filter holes are smaller than those of the first filter screen 9, which can perform high-precision filtration of gas and intercept fine particles such as PM2.5.

[0041] Working principle: When the C4 equipment needs to purify gas, the gas to be filtered enters the empty tank 18 through the inlet pipe 4, and then flows into the filter chamber 3. The gas first passes through the pretreatment screen 7, which intercepts large particulate impurities in the gas, such as hair and debris, preventing these large particles from entering the subsequent filter layers and reducing the burden on the subsequent filter layers.

[0042] Next, the pretreated gas enters the first filter screen 9, which filters out medium-sized particulate impurities in the gas, further purifying it. Then, the gas reaches the second filter screen 11, which filters the gas with even higher precision, intercepting fine particles such as PM2.5, achieving deep purification of the gas.

[0043] The purified gas is discharged from the machine body 1 through the exhaust pipe 5, completing the entire filtration process.

[0044] After a period of use, a large amount of large particles of impurities will accumulate on the surface of the pretreatment screen 7. At this time, pulling the pull plate 19 will cause the sliding plate 6 to move smoothly along the slide rail 13 with the cooperation of the sliding plate 12 and the slide rail 13, pulling the pretreatment screen 7 out of the filter chamber 3 for easy cleaning. At the same time, the scraper 16 at the bottom of the sliding plate 6 scrapes away the impurities on the surface of the first filter screen 9 as the sliding plate 6 moves. After cleaning, releasing the pull plate 19 will cause the return spring 15 to push the baffle 14, causing the sliding plate 6 to automatically return to its original position and continue the filtration process.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
