Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a ventilation device with dust removal function. Background Technology

[0002] Ventilation, also known as air exchange, is the process of mechanically or naturally introducing sufficient fresh air into an indoor space while simultaneously expelling polluted air that does not meet hygiene requirements, so that the indoor air meets hygiene requirements and the needs of the production process. All facilities in a building that perform ventilation are collectively called ventilation equipment. Ventilation equipment includes exhaust fans, ventilation fans, and blowers, and is further divided into industrial and household types.

[0003] The existing utility model with authorization announcement number CN216714437U discloses a coal mine ventilation device with dust removal function, including a mounting base and an exhaust device and an extraction device installed on the mounting base. The exhaust device includes a mounting cylinder, fan blades, scraper, air inlet box, and collection box. The air inlet box and collection box are installed on the mounting cylinder, the fan blades are installed inside the mounting cylinder, and the scraper is located at the air inlet box opening. The extraction device includes an air guide box, an air delivery pipe, an air suction pipe, and an air pump. The air guide box is connected to the air pump output end through the air delivery pipe.

[0004] The above technical solution uses a dust filter to block dust, and a scraper repeatedly scrapes the dust filter, causing dust on one side to fall into the collection box, thus preventing the dust filter from clogging and collecting it inside the collection box to prevent dust from returning to the well. Fresh air is drawn in by the air pump and guided by the rotating fan inside the casing to be discharged evenly, thus making the airflow more uniform. However, in the above technical solution, the ventilation device with dust removal function uses a filter screen installed before the ventilation fan to filter floating dust in the ventilation air, and uses the movement of the scraper to clean and remove the dust adsorbed on one side of the filter screen. However, because the scraper can easily cause some dust to get directly stuck in the filter screen, the filter screen will become clogged, reducing the ventilation effect of the ventilation device.

[0005] Therefore, those skilled in the art have provided a ventilation device with dust removal function to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this utility model is to provide a ventilation device with dust removal function. By using the extension and retraction of the hammer, the dust filter is knocked out and the dust blocked in the filter is knocked out. This avoids the movement of the scraper plate scraping the dust into the mesh, which would affect the ventilation effect of the dust filter.

[0007] This utility model provides the following technical solution: a ventilation device with dust removal function, including a wall, a ventilation duct fixedly connected to the inner wall of the wall, a dust filter screen provided at one end of the ventilation duct, a cleaning mechanism provided on the side of the wall, the cleaning mechanism being located on the side of the dust filter screen, the cleaning mechanism including two fixing plates, the fixing plates being connected to the side of the wall, the dust filter screen being connected between the two fixing plates, a driving hydraulic rod fixedly connected to each of the two fixing plates, the ends of the driving hydraulic rods on both sides being connected to the same scraping plate, the scraping plate contacting the dust filter screen, two sets of high-frequency telescopic hydraulic rods fixedly fixed to the two end faces of the scraping plate, pressure sensors fixedly connected to the telescopic ends of the high-frequency telescopic hydraulic rods, and a hammer fixedly connected to the sensing end of each set of pressure sensors, the hammer contacting the dust filter screen.

[0008] According to the above technical solution, the ventilation duct is provided with a ventilation fan bracket and a mounting bracket inside. The ventilation fan bracket is formed on one side of the mounting bracket, and the mounting bracket is connected to one end face of the ventilation duct by fasteners.

[0009] According to the above technical solution, a rotating motor is fixed on the inner wall of the ventilation fan bracket, and the output end of the rotating motor is connected to a rotating fan blade. The rotating motor drives the rotating fan blade to rotate, generating wind power and improving the ventilation effect.

[0010] According to the above technical solution, an upper limit block and a lower limit block are formed on one side of the wall. The upper limit block and the lower limit block are both located between two fixed plates. A sliding groove is provided on the upper limit block and the lower limit block. The dust filter is inserted into the sliding groove. The sliding groove makes it easy to insert and remove the dust filter, and facilitates the replacement of the dust filter.

[0011] According to the above technical solution, the upper and lower ends of the dust filter are fixed with sliding blocks, which cooperate with the sliding groove. The cooperation between the sliding block and the sliding groove is used to position the dust filter and prevent the dust filter from moving.

[0012] According to the above technical solution, a pull plate is formed on the sliding block at the upper end of the dust filter. The size of the pull plate is larger than the size of the upper limit block. A pull handle is connected to the upper end of the pull plate. The dust filter is limited by the pull plate to prevent the dust filter from sliding out of the sliding groove.

[0013] According to the above technical solution, a reinforcing ring is fixed on the surface of the scraper plate. The reinforcing ring is connected to the telescopic end of the driving hydraulic rod, thereby enhancing the connection strength between the scraper plate and the driving hydraulic rod.

[0014] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: by connecting high-frequency telescopic hydraulic rods to both ends of the scraper plate, and connecting hammers to the high-frequency telescopic hydraulic rods, the hammers are used to strike the dust filter screen, knocking out the dust blocking the mesh of the dust filter screen, thus avoiding the scraper plate scraping dust into the mesh and clogging the dust filter screen, which would affect the ventilation effect.

[0021] 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.

[0022] Please see Figures 1 to 4This utility model provides a technical solution: a ventilation device with dust removal function, including a wall 1, a ventilation duct 3 fixedly connected to the inner wall of the wall 1, a dust filter 201 provided at one end of the ventilation duct 3, and a cleaning mechanism 2 provided on the side of the wall 1. The cleaning mechanism 2 is located on the side of the dust filter 201 and includes two fixing plates 202 connected to the side of the wall 1. The dust filter 201 is connected between the two fixing plates 202. In this embodiment, the dust filter 201 is inserted into the upper limit block 10 and the lower limit block. Within the sliding groove 12 of 11, the dust filter 201 can also be installed in other ways, such as by creating a groove on the side of the fixing plate 202 and inserting the dust filter 201 into the groove. Both fixing plates 202 are fixedly connected to driving hydraulic rods 203, and the ends of both driving hydraulic rods 203 are connected to the same scraper plate 204. The scraper plate 204 is adjusted on both sides by the driving hydraulic rods 203, making its movement more stable. The scraper plate 204 is perpendicular to the dust filter 201, and the scraper plate 204... 4. The scraper plate 204 is attached to the dust filter 201. The scraper plate 204 moves to scrape the dust off the filter 201. Simultaneously, the scraper plate 204 also traps some dust inside the filter 201. Two sets of high-frequency telescopic hydraulic rods 205 are fixed to both ends of the scraper plate 204. Pressure sensors 206 are fixedly connected to the telescopic ends of the high-frequency telescopic hydraulic rods 205. The pressure sensors 206 are model M5156-000005-250BG. Each pressure sensor 206 is connected to a P... The LC controller is connected to the high-frequency telescopic hydraulic rod 205.

The extension and retraction of the high-frequency telescopic hydraulic rod 205 controls the hammer 207 to strike the dust. The hammering cleans the dust inside the dust filter mesh, reducing the problem of filter clogging and improving the ventilation effect of the ventilation device. At the same time, the pressure sensor 206 controls the pressure of the hammer 207 to prevent the dust filter 201 from deforming due to excessive hammering pressure.

[0023] like Figure 3 As shown, the ventilation duct 3 is equipped with a ventilation fan bracket 7 and a mounting bracket 5. The ventilation fan bracket 7 is formed on one side of the mounting bracket 5 and is snapped into the ventilation duct 3. The mounting bracket 5 connects the mounting bolt 6 to the threaded hole 4 on one end face of the ventilation duct 3 by passing through the mounting bolt 6. By setting the ventilation fan bracket 7, it is convenient to install the fan and improve the ventilation performance of the ventilation duct 3.

[0024] A rotating motor 8 is fixed on the inner wall of the ventilation fan bracket 7. The output end of the rotating motor 8 is connected to a rotating fan blade 9. The rotating motor 8 controls the rotation of the rotating fan blade 9, so that the rotating fan blade 9 generates wind power and enhances the ventilation effect.

[0025] like Figure 2 As shown, an upper limit block 10 and a lower limit block 11 are formed on one side of the wall 1. The upper limit block 10 and the lower limit block 11 are both located between two fixed plates 202. Sliding grooves 12 are provided on the upper limit block 10 and the lower limit block 11. The dust filter 201 is inserted into the sliding groove 12, which facilitates the disassembly and replacement of the dust filter 201.

[0026] like Figure 4 As shown, the upper and lower ends of the dust filter 201 are both fixed with sliding blocks 13. The sliding blocks 13 cooperate with the sliding groove 12 and slide within the sliding groove 12 to facilitate the insertion and guidance of the dust filter 201 and prevent the dust filter 201 from shifting during use.

[0027] A pull plate 14 is formed on the sliding block 13 at the upper end of the dust filter 201. The size of the pull plate 14 is larger than the size of the upper limit block 10. The pull plate 14 limits the dust filter 201 to prevent it from sliding out of the sliding groove 12. A pull handle 15 is connected to the upper end of the pull plate 14. By pulling the pull handle 15, the dust filter 201 can be pulled out of the sliding groove 12, making it convenient to manually replace the dust filter 201.

[0028] A reinforcing ring 16 is fixed on the surface of the scraper 204. The reinforcing ring 16 is connected to the telescopic end of the drive hydraulic rod 203, which enhances the contact area and connection strength between the scraper 204 and the drive hydraulic rod 203.
