Description

Technical Field

[0001] This utility model relates to the field of dust collector technology, specifically to a dust collection device for a dust collector. Background Technology

[0002] A dust collector is a device that separates dust from flue gas. A dust collector consists of a fan, a pulse jet cleaner, a filter element, and a dust collection device (dust collection box). When in operation, the fan draws gas into the dust collector, and the gas passes through the filter element to filter the dust. When not in use, the pulse jet cleaner cleans the filter element and blows the dust on the side wall of the filter element into the dust collection device, thus achieving automatic filtration and cleaning in one unit.

[0003] For example, a dust collection device for a dust collector, with application number CN202222015854.X and authorization announcement date of 20230303, solves the problem in the prior art where, due to the open top of the dust collection box, dust inside the box is blown into the air by the wind when workers walk around emptying it, causing dust to be easily inhaled by factory workers and affecting their health. The dust collection device includes a dust collector body with a fan mounted on it. An air inlet pipe is fixedly connected to the right end of the dust collector body. Multiple doors are located at the front end of the dust collector body. An installation groove is provided inside the dust collector body, and a dust collection box is slidably connected within the installation groove. The dust collection box contains shielding and guiding components to prevent dust from scattering into the air. This utility model can seal the top of the dust collection box, preventing dust from scattering into the air when workers walk around emptying the dust collection box.

[0004] During the operation of a dust collector, dust is trapped on the surface of the filter element and falls into the dust collection device after being cleaned by backflushing. However, when the dust collector collects dust, the collected dust will cover the dust collection device, making subsequent cleaning difficult and unable to quickly remove dust from all parts of the dust collection device. Therefore, it is urgent to design a dust collection device for dust collectors to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a dust collection device for a dust collector to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A dust collection device for a dust collector includes a tank. A discharge assembly is bolted to one side of the bottom outer wall of the tank. An installation shaft is mounted inside the tank via a bearing. Multiple scrapers are welded to one side of the top outer wall of the installation shaft, with the top of the scrapers contacting the inner wall of the tank. Multiple mounting seats are mounted to one side of the bottom outer wall of the installation shaft via a flat key, and brush plates are bolted to one side of the mounting seats. A drive motor is bolted to one side of the outer wall of the tank, and the output end of the drive motor is fixedly connected to one end of the installation shaft via a coupling.

[0008] Furthermore, multiple mounting rings are bolted inside the tank, and filter screens are bolted inside the mounting rings. The mounting base passes through the filter screen, and the mounting base is mounted to the filter screen via bearings.

[0009] Furthermore, an air inlet pipe is inserted into one end of the tank, an air extraction pipe is inserted into the other end of the tank, and bases are bolted to the outer walls on both sides of the bottom of the tank.

[0010] Furthermore, a sound insulation cavity is provided in the inner wall of the tank, and the sound insulation cavity is filled with sound insulation blocks.

[0011] Furthermore, the discharge assembly includes a discharge shell, the top of which is bolted to the outer wall of the bottom side of the tank, and the discharge shell is in communication with the tank.

[0012] Furthermore, an insertion groove is provided on one side of the outer wall of the discharge shell, and a baffle is inserted into the insertion groove. A connecting plate is welded to one side of the outer wall of the baffle.

[0013] Furthermore, three electric push rods are bolted to the outer wall of one side of the discharge shell, and the output ends of the three electric push rods are mounted together with the connecting plate.

[0014] In the above technical solution, the dust collection device for a dust collector provided by this utility model has the following beneficial effects:

[0015] (1) When it is necessary to discharge the dust inside the tank, the drive motor is started by setting the drive motor, mounting shaft and scraper. The drive motor will drive the mounting shaft to rotate. The scraper set on the mounting shaft will dynamically contact the inner wall of the tank and scrape off the dust attached to the inner wall in real time. This will make the dust on the top and sides of the tank concentrated and scraped to the bottom of the tank, which will facilitate the subsequent centralized discharge of the dust inside the tank and reduce the difficulty of cleaning.

[0016] (2) When the mounting shaft rotates, the brush plate will rotate with the mounting shaft. The rotating brush plate will flexibly rub against the surface of the filter screen. Combined with the pulse backflushing of the dust collector, a "mechanical + airflow" synergistic dust removal mode can be formed, which can effectively remove sticky dust and caking layer, avoid filter screen blockage, reduce wind resistance and extend filter screen life.

[0017] (3) Through the set discharge component, the discharge component realizes the closed discharge control through the electric push rod linkage baffle. During discharge, the electric push rod drives the baffle to slide along the insertion slot to open the discharge shell, and the dust falls to the external collection container by gravity. After the discharge is completed, the baffle is reset and sealed. There is no manual intervention and zero dust leakage throughout the process, which solves the problem of secondary pollution when the traditional open dust collection box is tilted.

[0018] (4) By setting up sound insulation cavity and sound insulation block, the sound insulation cavity on the inner wall of the tank is filled with sound insulation block. When this device is applied, the sound insulation block can absorb the noise generated by the drive motor and airflow, thereby reducing the operating noise of the equipment.

[0030] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0031] like Figure 1-8 As shown in the figure, a dust collection device for a dust collector provided by this utility model includes a tank 2. A discharge assembly 6 is bolted to one side of the bottom outer wall of the tank 2. An installation shaft 9 is installed inside the tank 2 via a bearing. Multiple scrapers 10 are welded to one side of the top outer wall of the installation shaft 9. The top of the scrapers 10 contacts the inner wall of the tank 2. Multiple mounting seats 11 are mounted to one side of the bottom outer wall of the installation shaft 9 via a flat key. A brush plate 12 is bolted to one side of the outer wall of the mounting seat 11. A drive motor 5 is bolted to one side of the outer wall of the tank 2. The output end of the drive motor 5 is fixedly connected to one end of the installation shaft 9 via a coupling.

[0032] Specifically, in this embodiment, a tank body 2 is included. A discharge assembly 6 is bolted to one side of the bottom outer wall of the tank body 2. An installation shaft 9 is installed inside the tank body 2 via a bearing. Multiple scrapers 10 are welded to one side of the top outer wall of the installation shaft 9, with the top of the scrapers 10 contacting the inner wall of the tank body 2. Multiple mounting seats 11 are mounted to one side of the bottom outer wall of the installation shaft 9 via a flat key. A brush plate 12 is bolted to one side of the outer wall of the mounting seat 11. A drive motor 5 is bolted to one side of the outer wall of the tank body 2. The drive motor 5 is preferably an STP-59D3039 model. The drive motor 5 drives the installation shaft 9 to rotate at a uniform speed. Multiple scrapers 10 on the top of the mounting shaft 9 rotate with the shaft, and their tops are in continuous contact with the inner wall of the tank 2, scraping off the dust adhering to the inner wall and guiding it to the bottom of the tank 2 to prevent dust accumulation and caking. The mounting base 11 at the bottom of the mounting shaft 9 rotates synchronously, causing the bolt-fixed brush plate 12 to flexibly contact the surface of the filter screen 8. During the rotation, the brush plate 12 mechanically brushes the filter screen 8. Combined with the high-pressure airflow impact of the dust collector's pulse back-flushing system, a synergistic dust removal effect of "mechanical brushing + airflow stripping" is formed, effectively removing sticky dust and caking layers. The output end of the drive motor 5 is fixedly connected to one end of the mounting shaft 9 through a coupling.

[0033] The dust collection device for a dust collector provided by this utility model allows for the activation of a drive motor 5 when dust needs to be discharged from inside the tank 2. The drive motor 5 drives the mounting shaft 9 to rotate, and the scraper 10 set on the mounting shaft 9 dynamically contacts the inner wall of the tank 2, scraping away the dust adhering to the inner wall in real time. This concentrates the dust on the top and sides of the tank 2 and scrapes it to the bottom of the tank 2, making it easier to discharge the dust inside the tank 2 in a concentrated manner and reducing the difficulty of cleaning.

[0034] In one embodiment provided by this utility model, such as Figure 1-5 As shown, multiple mounting rings 7 are bolted inside the tank body 2, and filter screens 8 are bolted inside the mounting rings 7. The mesh size of the multiple filter screens 8 decreases in stages. As the gas flows towards the filter screens 8, dust particles are trapped on their surface. The mounting base 11 passes through the filter screens 8 and is mounted to the filter screens 8 by bearings. An air inlet pipe 4 is inserted into one end of the tank body 2 to facilitate the flow of dust-laden gas into the tank body 2. An exhaust pipe 3 is inserted into the other end of the tank body 2 and is installed together with the dust collector fan. Bases 1 are bolted to the outer walls on both sides of the bottom of the tank body 2. A sound insulation cavity 13 is opened in the inner wall of the tank body 2, and the sound insulation cavity 13 is filled with sound insulation blocks 14. The sound insulation blocks 14 are made of sound insulation cotton. The sound insulation cavity 13 filled with sound insulation blocks 14 can absorb the vibration and noise generated by the operation of the drive motor 5 and the airflow, thereby reducing the operating noise of the equipment.

[0035] In another embodiment provided by this utility model, such as Figure 6-8 As shown, the discharge assembly 6 includes a discharge shell 15. The top of the discharge shell 15 is bolted to the outer wall of one side of the bottom of the tank body 2. The discharge shell 15 and the tank body 2 are interconnected. An insertion groove 19 is provided on one side of the outer wall of the discharge shell 15, and a baffle 17 is inserted into the insertion groove 19. The baffle 17 is sealed to the insertion groove 19 by a sealing strip. A connecting plate 18 is welded to one side of the outer wall of the baffle 17. Three electric push rods 16 are bolted to one side of the outer wall of the discharge shell 15. The electric push rods 16 are of superior model. When the discharge assembly 6 is activated, the three electric push rods 16 will simultaneously push the connecting plate 18, causing the baffle 17 to slide along the insertion slot 19, opening the discharge port of the discharge shell 15. Subsequently, the dust accumulated at the bottom of the tank 2 will fall into the external collection container through the discharge shell 15 under the action of gravity. After the discharge is completed, the electric push rods 16 will retract and drive the baffle 17 to reset, achieving full closure of the discharge port. There is no dust leakage throughout the process, and the output ends of the three electric push rods 16 are installed together with the connecting plate 18.

[0036] Example 1

[0037] A dust collection device for a dust collector includes a tank body 2. A discharge assembly 6 is bolted to one outer wall at the bottom of the tank body 2. An installation shaft 9 is mounted inside the tank body 2 via bearings, and multiple scrapers 10 are welded to one outer wall at the top of the installation shaft 9. The tops of the scrapers 10 contact the inner wall of the tank body 2. Multiple mounting seats 11 are mounted to one outer wall at the bottom of the installation shaft 9 via flat keys, and brush plates 12 are bolted to one outer wall of each mounting seat 11. A drive motor 5 is bolted to one outer wall of the tank body 2. The drive motor 5 is preferably an STP-59D3039 model. The drive motor 5 drives the installation shaft 9 to rotate at a uniform speed. Multiple scrapers 10 on the top of the mounting shaft 9 rotate with the shaft, and their tops are in continuous contact with the inner wall of the tank 2, scraping off the dust adhering to the inner wall and guiding it to the bottom of the tank 2 to prevent dust accumulation and caking. The mounting base 11 at the bottom of the mounting shaft 9 rotates synchronously, causing the bolt-fixed brush plate 12 to flexibly contact the surface of the filter screen 8. During the rotation, the brush plate 12 mechanically brushes the filter screen 8. Combined with the high-pressure airflow impact of the dust collector's pulse back-flushing system, a synergistic dust removal effect of "mechanical brushing + airflow stripping" is formed, effectively removing sticky dust and caking layers. The output end of the drive motor 5 is fixedly connected to one end of the mounting shaft 9 through a coupling.

[0038] Example 2

[0039] This embodiment further defines the features of Embodiment 1. Multiple mounting rings 7 are bolted inside the tank body 2, and filter screens 8 are bolted inside each mounting ring 7. The mesh size of the multiple filter screens 8 decreases progressively. Gas flows towards the filter screens 8, and dust particles are trapped on their surface. A mounting base 11 passes through the filter screens 8 and is mounted to the filter screens 8 via bearings. An air inlet pipe 4 is inserted into one end of the tank body 2, facilitating the flow of dust-laden gas into the tank body 2. An exhaust pipe 3 is inserted into the other end of the tank body 2, and is mounted to the dust collector fan. Bases 1 are bolted to the outer walls on both sides of the bottom of the tank body 2. A sound insulation cavity 13 is formed in the inner wall of the tank body 2, and the sound insulation cavity 13 is filled with sound insulation blocks 14 made of sound insulation cotton. The sound insulation cavity 13 filled with sound insulation blocks 14 can absorb the vibration and noise generated by the operation of the drive motor 5 and the airflow, thus reducing the operating noise of the equipment. The discharge assembly 6... The system includes a discharge shell 15, the top of which is bolted to the outer wall of one side of the bottom of the tank body 2. The discharge shell 15 is interconnected with the tank body 2. An insertion groove 19 is provided on one side of the outer wall of the discharge shell 15, and a baffle 17 is inserted into the groove 19. The baffle 17 is sealed to the groove 19 by a sealing strip. A connecting plate 18 is welded to one side of the outer wall of the baffle 17. Three electric push rods 16 are bolted to one side of the outer wall of the discharge shell 15. Preferably, the electric push rods 16 are of the following type: [missing information - likely a specific type]. When the material assembly 6 is started, the three electric push rods 16 will simultaneously push the connecting plate 18, causing the baffle 17 to slide along the insertion slot 19, opening the discharge port of the discharge shell 15. Then, the dust accumulated at the bottom of the tank 2 will fall into the external collection container through the discharge shell 15 under the action of gravity. After the discharge is completed, the electric push rods 16 will retract and drive the baffle 17 to reset, realizing the full sealing of the discharge port. There is no dust leakage throughout the process, and the output ends of the three electric push rods 16 are installed together with the connecting plate 18.

[0040] Working principle: When the dust collector is working, dust-laden gas enters the tank 2 through the inlet pipe 4. Under the negative pressure of the dust collector fan connected to the exhaust pipe 3, the gas flows towards the filter screen 8. Dust particles are trapped on the surface of the filter screen 8. The purified gas passes through the filter screen 8 and is discharged through the exhaust pipe 3, completing gas-solid separation. After the dust collector finishes dust removal, the drive motor 5 drives the mounting shaft 9 to rotate at a constant speed. Multiple scrapers 10 welded to the top of the mounting shaft 9 rotate with the shaft, and their tops are in continuous contact with the inner wall of the tank 2, scraping off the dust adhering to the inner wall and guiding it to the bottom of the tank 2 to prevent dust accumulation and caking. At the same time, the mounting base 11 at the bottom of the mounting shaft 9 rotates synchronously, driving the bolt-fixed brush plate 12 to flexibly contact the surface of the filter screen 8. The brush plate 12 mechanically brushes the filter screen 8 during rotation, combined with the high-pressure airflow of the dust collector's pulse back-flushing system. The impact creates a synergistic dust removal effect of "mechanical brushing + airflow stripping", effectively removing sticky dust and caking layers. The dust that is subsequently removed settles to the bottom of the tank 2 under gravity. When the dust at the bottom of the tank 2 accumulates to a set amount, the discharge assembly 6 is activated. During this process, three electric push rods 16 simultaneously push the connecting plate 18, causing the baffle 17 to slide along the insertion groove 19, opening the discharge port of the discharge shell 15. Subsequently, the dust accumulated at the bottom of the tank 2 falls into the external collection container through the discharge shell 15 under gravity. After the discharge is completed, the electric push rods 16 retract and drive the baffle 17 to reset, achieving a complete closure of the discharge port and preventing dust leakage throughout the process. At the same time, when the dust collection device is running, the sound insulation cavity 13 on the inner wall of the tank 2 is filled with sound insulation blocks 14, which can absorb the vibration and noise generated by the operation of the drive motor 5 and the airflow, reducing the operating noise of the equipment.

[0041] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
