Description

Technical Field

[0001] The utility model relates to the technical field of electrostatic dust removal, in particular to an electrostatic dust removal device. Background Art

[0002] Asphalt fume is a common industrial waste gas, containing large amounts of fine particulate matter, volatile organic compounds, and toxic and hazardous gases. These components not only pollute the environment but also pose a threat to human health. Electrostatic precipitators, as highly efficient air purification devices, are widely used in asphalt fume treatment. They operate by charging dust particles through an electric field, which then traps them on a dust collecting plate through electrostatic force. However, due to the unique properties of asphalt fume, dust adhering to the dust collecting plate is highly adhesive, making it difficult to completely remove using traditional mechanical vibration cleaning and airflow backwashing, resulting in poor cleaning results. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide a device which can further clean the stubborn dust attached to the dust collecting plate after the traditional mechanical vibration cleaning, thereby ensuring that the electrostatic dust removal device can operate stably for a long time.

[0004] The technical solution adopted by the present utility model is: an electrostatic dust removal device, comprising a shell, air inlets and exhaust ports are provided on both sides of the shell, and a dust hopper for collecting dust is provided at the bottom of the shell, and a cathode wire and a dust collecting plate for electrostatic dust removal are provided inside the shell, wherein the cathode wire is arranged between the two dust collecting plates arranged opposite to each other, and the cathode wire is connected to the top of the dust collecting plate and the mounting plate, the mounting plate is fixed to the top of the shell, and a scraping mechanism for cleaning stubborn dust is provided on the top of the dust collecting plate, the motor in the scraping mechanism is installed on the top surface of the mounting plate, the motor is connected to a screw, the screw is connected to a lifting frame, and the end of the screw away from the motor is connected to the mounting frame.

[0005] The above structure has the following beneficial effects:

[0006] A scraping mechanism is set on the top of the dust collecting plate, and the motor in the scraping mechanism is installed on the top surface of the mounting plate. The motor is connected to the lead screw, and the other end of the lead screw is connected to the mounting frame. A lifting frame is set on the lead screw. When the motor is started, the motor will drive the lead screw to rotate, and then drive the lifting frame to move in the vertical direction. At this time, as the lifting frame moves, the stubborn dust on the dust collecting plate that is difficult to clean will be scraped off, thereby realizing the cleaning of the stubborn dust.

[0007] Preferably, a first through hole and a second through hole are provided on the lifting frame, the cathode wire passes through the first through hole, and the dust collecting plate passes through the second through hole.

[0008] The setting of the first through hole and the second through hole ensures that the cathode wire and the dust collecting plate will not be obstructed when the lifting frame moves, ensures the effective spatial layout of the cathode wire and the dust collecting plate, enables smooth dust collection, and ensures the effective operation of the electrostatic dust removal device.

[0009] Preferably, a slide groove is provided on the inner side of the installation frame, and a slider is provided on the outer side wall of the lifting frame, and the slider is slidably connected to the slide groove.

[0010] The design of the slider and the slide groove ensures the stability of the lifting frame when it moves in the vertical direction, reduces the vibration and shaking caused by the operation of the equipment, and improves the working accuracy of the scraping mechanism. The slide groove provides a precise moving path for the scraping mechanism, so that the scraping mechanism can accurately cover the entire dust collecting plate surface, avoiding incomplete or omission scraping and improving the cleaning effect.

[0011] Preferably, two symmetrically arranged scraping strips are installed on the inner side of the second through hole.

[0012] The design of the scraping strip can effectively remove stubborn dust on the dust collecting plate, especially those dust particles with strong adhesion, which effectively improves the dust removal efficiency of the scraping mechanism.

[0013] Preferably, the scraping strip is made of soft material.

[0014] The scraping strips made of soft material can effectively avoid scratches or other physical damage to the dust collecting plate during the cleaning process, thereby extending the service life of the dust collecting plate and reducing maintenance costs.

[0015] Preferably, first scrapers are installed on both the top and bottom surfaces of the lifting frame.

[0016] The setting of the first scraper can further enhance the cleaning effect of stubborn dust on the dust collecting plate. When too much dust accumulates on the dust collecting plate, dust clumps may be formed. At this time, the scraping bar is difficult to clean the dust clumps. The first scraper can first process the dust clumps, remove the dust clumps, and then the scraping bar will clean them.

[0017] Preferably, a bending section is provided at one end of the first scraper away from the lifting frame.

[0018] The design of the bending section enables the first scraper to fit more closely to the surface of the dust collecting plate, ensuring that the dust lumps attached to the dust collecting plate can be effectively removed, and due to the bending design, one end of the first scraper is inclined. The inclined design helps to guide the scraped dust lumps to slide along the surface of the scraper, reducing the possibility of dust adhering to the dust collecting plate again, ensuring that the dust can fall smoothly into the ash hopper, and improving the cleaning effect.

[0019] Preferably, bosses and grooves are provided on the top and bottom surfaces of the lifting frame, and the grooves are connected to the second scraper.

[0020] The design of the boss and groove makes it easier to install and disassemble the second scraper. Different types of scrapers can be replaced according to the actual situation on site, which improves the flexibility and adaptability of the equipment. It also allows the scraper to be replaced in time when it is worn or damaged, without the need to replace the entire lifting frame.

[0021] Preferably, a tenon is provided at one end of the second scraper, the tenon cooperates with the groove, and the second scraper is fixed to the boss by bolts.

[0022] The tenon on the second scraper matches the groove on the lifting frame and is connected by bolts, which not only ensures the stability and reliability of the scraper during operation, but also simplifies the scraper replacement process and reduces maintenance difficulty.

[0035] The following is further described in conjunction with specific embodiments. Figure 1-3As shown, this embodiment is an electrostatic dust removal device, comprising a shell 1, with an air inlet 2 and an exhaust port 3 respectively provided on both sides of the shell 1, and an ash hopper 4 for collecting dust provided at the bottom of the shell 1, and two ash hoppers 4 are provided; a cathode wire 11 and a dust collecting plate 12 for electrostatic dust removal are provided inside the shell 1, wherein the cathode wire 11 is provided between two dust collecting plates 12 provided opposite to each other, and is at a distance from one end of the dust collecting plate 12; and the cathode wire 11 and the dust collecting plate 12 are arranged in sequence from the air inlet 2 to the air outlet, wherein the cathode wire 11 and the dust collecting plate 12 are arranged in multiple groups, wherein the cathode wire 11 and the dust collecting plate 12 are arranged in sequence The top of each of the dust collecting plates 12 is connected to the mounting plate 5 provided on the top of the housing 1; a scraping mechanism for cleaning the stubborn dust on the dust collecting plate 12 is provided on the top of the dust collecting plate 12, and the scraping mechanism includes a motor 6, a lead screw 7, a lifting frame 8, and a mounting frame 9, wherein the motor 6 is fixedly mounted on the top surface of the mounting plate 5 by a bolt 18, and the output end of the motor 6 is connected to the lead screw 7 through a coupling, and a mounting frame 9 is welded and fixed on the bottom surface of the mounting plate 5, and the mounting frame 9 is a "U"-shaped frame, and the bottom surface of the "U"-shaped frame is rotatably connected to the bottom end of the lead screw 7, and The lead screw 7 is connected to the lifting frame 8 through the threaded hole 803 provided on the lifting frame 8, and the lead screw 7 is driven by the motor 6, thereby driving the lifting frame 8 connected to the lead screw 7 to move in the vertical direction; in order to make the lifting frame 8 more stable during the movement, a slide groove 901 is provided on the inner side of the mounting frame 9, and a slider 902 is provided on the outer wall of the lifting frame 8. The slider 902 is slidably connected to the slide groove 901, thereby making the lifting frame 8 more stable when moving according to the preset moving path. , to prevent unnecessary shaking during movement; a first through hole 801 and a second through hole 802 are provided on the lifting frame 8, and the cathode wire 11 passes through the first through hole 801, and the dust collecting plate 12 passes through the second through hole 802, so that the lifting frame 8 avoids being blocked in its moving path when cleaning stubborn dust on the dust collecting plate 12; a scraping strip 10 is relatively installed on the inner side of the second through hole 802, and the scraping strip 10 is made of a soft material, such as rubber material, which can effectively avoid damage that may be caused when scraping the dust collecting plate 12.

[0036] Working principle:

[0037] During use, the air flow carrying dust flows through multiple groups of dust collecting plates 12 and cathode wires 11 arranged inside the shell 1, wherein a strong electric field is generated between the cathode wires 11 and the dust collecting plates 12, and the cathode wires 11 release a large number of electrons, causing the passing gas molecules to be ionized, forming a large number of negatively charged examples. As the gas flows, these charged ions will contact the dust particles and adhere to the dust collecting plates 12. As time goes by, the dust on the dust collecting plates 12 accumulates more and more, and it is necessary to clean it regularly. At this time, it can be removed by the scraping mechanism provided. The motor 6 drives the screw 7 to rotate, and then drives the lifting frame 8 to move in the vertical direction. The slider 902 provided on the lifting frame 8 and the slide groove 901 provided on the mounting frame 9 can make the lifting frame 8 more stable when moving, and the stubborn dust on the dust collecting plate 12 is removed by the scraping strip 10 provided in the second through hole 802 in the lifting frame 8.

[0041] like Figure 6-7 As shown, this embodiment adds a detachable design on the basis of Example 2. By providing a boss 14 and a groove 15 on the top and bottom surfaces of the lifting frame 8, the second scraper 16 can be detached and installed with the lifting frame 8. The second scraper 16 is provided with a tenon 17, which cooperates with the groove 15 so that the second scraper 16 is embedded in the supporting groove 15, and the second scraper 16 and the lifting frame 8 are fixed by a bolt 18. The detachable design allows the scraper to be replaced when the scraping effect is poor, saving costs. The scraper can also be customized according to the on-site conditions to achieve a better scraping effect.
