Description

Technical Field

[0001] This invention relates to the field of environmental engineering construction technology, specifically to an industrial explosion-proof dust collector. Background Technology

[0002] In industrial settings such as machining, building materials production, and warehousing and logistics, processes like material crushing, screening, conveying, loading and unloading, grinding, and mixing continuously generate large amounts of dust, which easily accumulates on equipment surfaces, inside pipes, on workshop floors, and in the surrounding space. Excessive dust not only hinders equipment heat dissipation, causes lubrication failure, and reduces operational accuracy, resulting in product contamination and affecting quality, but it also deteriorates the air quality in the working environment, endangering the respiratory health of employees, and even creating a potential explosion hazard due to excessive dust concentration.

[0003] Industrial explosion-proof dust collectors are devices specifically designed for the safe removal of dust, particulate matter, or other combustible substances in flammable and explosive environments. They are widely used in industrial sites with explosion risks. Their core objective is to efficiently remove dust while preventing dust explosions through special design, ensuring production safety. In industrial environments, combustible dust (such as metal powder, wood chips, and chemical dust) may explode when it reaches a certain concentration and encounters an ignition source or static electricity. Explosion-proof dust collectors reduce the risk by eliminating explosion conditions (such as isolating ignition sources, suppressing pressure, and inerting the environment). Dust-laden gas is drawn into the equipment by a fan, where the dust is trapped by the filter media. A pulse jet cleaning system then blows the dust from the filter media into a dust collection box, and the purified air is discharged. The pulse jet cleaning system periodically removes the accumulated dust from the filter media.

[0004] The operating principle of industrial dust collectors is based on a cyclical mechanism of dust-laden gas filtration and dust collection, with the core consisting of a dust collection tank, filter cartridges, and pulse cleaning components working together. Dust-laden gas enters the dust collection tank through a suction pipe under the action of a fan. The high-speed airflow first forms a vortex within the tank, causing large dust particles to settle to the bottom dust collection box due to centrifugal force. The remaining gas-dust mixture enters the filter cartridge filtration zone, where high-precision filter media (such as pleated fiber filter cartridges) deeply intercepts the dust, adsorbing fine dust onto the filter cartridge surface. Clean gas is then discharged through the compliant gas exhaust channel.

[0005] However, after the dust collector has been running for a period of time, the dust collection box will be full of dust. At this time, the dust collection box needs to be removed manually to clean the dust inside. However, due to the complexity of the industrial environment, or due to shaking during manual removal, the dust inside the dust collection box may be scattered and float out of the dust collection box, causing secondary pollution to the industrial environment. Therefore, this does not meet the existing needs. To address this, we have proposed an explosion-proof dust collector for industrial use. Summary of the Invention

[0006] This invention provides an industrial explosion-proof dust collector, which has the beneficial effect of compressing the dust in the dust collection box into blocks during operation, thus solving the problem mentioned in the background art where dust falls everywhere when the dust collection box is removed due to the uncertainty of the external environment.

[0013] As an optional solution for an industrial explosion-proof dust collector according to the present invention, the drive assembly includes a mounting bracket fixedly connected inside the suction pipe, a drive shaft rotatably connected inside the mounting bracket, a drive fan blade fixedly connected to one side of the drive shaft, and the extrusion shaft provided on the other side of the drive shaft.

[0014] As an optional solution for an industrial explosion-proof dust collector according to the present invention, the dust collection tank is provided with a limiting component, the limiting component including a limiting gear installed between the extrusion shaft and the drive shaft, a snap-fit ​​tooth block provided above the limiting gear, a limiting rod fixedly connected to the top of the snap-fit ​​tooth block, the limiting rod being slidably connected in a limiting groove, the limiting groove being opened in the dust collection tank, a limiting plate fixedly connected to the top of the limiting rod, and the bottom of the limiting plate being connected to the pulse airflow channel through a limiting spring.

[0015] As an optional solution for an industrial explosion-proof dust collector according to the present invention, wherein: a striking and shaking component is provided inside the triangular mounting block, the striking and shaking component includes a striking mounting block installed inside the triangular mounting block, a striking groove is opened inside the striking mounting block, a striking shaft is rotatably connected inside the striking groove, a striking ball is connected to the side wall of the striking shaft, a second steel wire is connected to one side of the striking ball, a slider is connected to the other end of the second steel wire, the slider is slidably connected in a track groove, the track groove is opened on one side of a disc, and the disc is fixedly connected to the side wall of the extrusion shaft.

[0017] The present invention has the following beneficial effects:

[0018] 1. The extrusion shaft and extrusion cam are driven synchronously by the drive shaft to rotate, and the extrusion rod is periodically pressed, so that the extrusion box repeatedly compacts the dust in the dust collection box. The dust that has been lumped together is heavier and has a denser structure, so it is easy to recycle even if it is accidentally scattered.

[0019] 2. When the pulse airflow channel backflushs high-pressure air onto the filter element, the airflow pressure forces the limiting plate to slide downwards along the limiting rod, causing the locking tooth block to instantly lock the limiting gear. This pauses the rotation of the extrusion shaft, preventing the extrusion action from interfering with the dust removal process and improving dust removal efficiency. Simultaneously, the mechanical locking mechanism provides dual protection during pulse airflow impact, preventing structural wear caused by dynamic contact between the extrusion cam and the extrusion rod, and avoiding the risk of secondary dust generation caused by the superposition of airflow disturbance and extrusion action.

[0020] 3. This industrial explosion-proof dust collector utilizes a striking and shaking component. The sliding block is driven by a disc track groove that rotates synchronously with the extrusion shaft. Combined with a torsion spring energy storage and release mechanism, this ensures that the striking balls impact the inner wall of the triangular mounting block at a precise frequency. This design converts the rotational motion of the extrusion shaft into high-frequency vibration without increasing energy consumption. This effectively removes dust that falls onto the upper surface of the triangular mounting block and other exposed structural surfaces during filter cleaning, preventing dust from entering the internal mechanical structure and causing obstruction, thus ensuring the stability of the device's operation.

Detailed Implementation

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1: This example aims to address the problem of dust scattering everywhere when the dust collection box 14 is removed due to the uncertainty of the external environment. Please refer to [link to example]. Figures 1 to 10 An industrial explosion-proof dust collector includes a dust collection device 1, which includes a dust collection tank 11. A dust collection box 14 is provided at the bottom of the dust collection tank 11. An extrusion assembly 2 is provided inside the dust collection tank 11. The extrusion assembly 2 includes a triangular mounting block 21 installed inside the dust collection tank 11. An extrusion shaft 23 is installed inside the triangular mounting block 21. The extrusion shaft 23 drives the extrusion box 28 to extrude the dust located in the dust collection box 14 under the drive of the drive assembly 4.

[0034] Dust collection tank 11 is equipped with a suction pipe 12 and a qualified gas exhaust channel 13 on both sides. A filter element 15 is installed inside the dust collection tank 11. A pulse cleaning component 16 is set above the filter element 15. The pulse cleaning component 16 is connected to a pulse airflow channel 17, which is opened inside the side wall of the dust collection tank 11.

[0035] Dust removal equipment 1 is used to absorb and treat dust in the industrial environment. The dust removal equipment 1 uses a fan to suck dust into the dust collection tank 11 through the suction pipe 12. The dust is filtered by the filter element 15, and the filtered air is discharged through the qualified gas exhaust channel 13, ensuring the cleanliness of the industrial environment. The dust attached to the filter element 15 is discharged intermittently under the action of the pulse cleaning component 16, and this dust is collected in the dust collection box 14, which is then cleaned regularly by the staff (the working principle and specific structure of the dust removal equipment 1 are existing technologies, so this solution will not describe them in detail).

[0036] An installation groove 22 is provided in the triangular mounting block 21, and an extrusion shaft 23 is provided in the installation groove 22. An extrusion cam 29 is fixedly connected to the side wall of the extrusion shaft 23. The extrusion cam 29 is used to drive the extrusion rod 25 to descend. An extrusion box 28 is fixedly connected to the bottom of the extrusion rod 25.

[0037] The extrusion rod 25 is slidably connected in the extrusion groove 24, which is opened in the triangular mounting block 21. An extrusion plate 26 is fixedly connected to the side wall of the extrusion rod 25, and the extrusion plate 26 is connected to the extrusion groove 24 through the extrusion spring 27.

[0038] The drive assembly 4 includes a mounting bracket 41 fixedly connected inside the suction pipe 12. A drive shaft 42 is rotatably connected inside the mounting bracket 41. A drive fan blade 43 is fixedly connected to one side of the drive shaft 42, and an extrusion shaft 23 is installed on the other side of the drive shaft 42.

[0039] As the fan operates, airflow enters the dust collection tank 11 through the suction pipe 12. The airflow first passes through the drive fan blades 43, causing the drive fan blades 43, the connected drive shaft 42, and the extrusion shaft 23 to rotate synchronously. The rotation of the extrusion shaft 23 causes the extrusion cam 29 on its side wall to rotate synchronously. The extrusion cam 29 drives the extrusion rod 25 to slide downwards, while the extrusion rod 25 slides upwards under the action of the extrusion spring 27. This design drives the extrusion rod 25 and the extrusion box 28 installed at the bottom of the extrusion rod 25 to continuously reciprocate. Since the extrusion box 28 is positioned above the dust collection box 14, it continuously compresses the dust inside the dust collection box 14, causing the scattered dust inside the dust collection box 14 to continuously... The dust is concentrated and formed into blocks. Compared to scattered dust, the concentrated blocky dust has a certain weight, so it will not easily fall everywhere when the dust collection box 14 is removed. Even if the dust falls out in blocks, the user can quickly put it back into the dust collection box 14. Scattered dust, on the other hand, falls in pieces and cannot be picked up again. Therefore, this blocky design can effectively prevent the problem of dust falling everywhere when the dust collection box 14 is removed, ensuring the cleanliness of the industrial environment. The inverted triangular design at the top of the triangular mounting block 21 allows the dust in the filter element 15 to slide down the slope into the dust collection box 14 when it falls, ensuring the operation of the internal structure of the triangular mounting block 21 and avoiding the influence of dust on the movement of the structure.

[0040] In practical use, the rotation speed of the extrusion shaft 23 is controlled by the airflow rate. Since the dust extrusion frequency does not need to be very fast, a speed reduction device (existing technology, such as planetary gear sets, etc., which will not be described in detail in this solution) can be set between the extrusion shaft 23 and the extrusion cam 29. By setting the speed reduction device, the rotation frequency of the extrusion cam 29 can be reduced, thereby reducing the frequency of dust being extruded into blocks.

[0041] The extrusion box 28 is provided with a telescopic component 3. The telescopic component 3 includes a telescopic groove 31 opened at the bottom of the extrusion box 28. A telescopic block 32 is slidably connected in the telescopic groove 31. A toothed groove 33 is opened on one side of the telescopic block 32. The toothed groove 33 is meshed with a gear 34. The gear 34 is rotatably connected in a rotating groove 35. The rotating groove 35 is opened in the extrusion box 28. A first fixed shaft 37 is fixedly connected in the rotating groove 35. The first fixed shaft 37 and the gear 34 are connected by a first torsion spring 38.

[0042] A first winding rope groove 36 is provided on the side wall of the gear 34. A first steel wire 39 is wound in the first winding rope groove 36. The other end of the first steel wire 39 is fixedly connected to the bottom of the triangular mounting block 21.

[0043] During the descent of the extrusion box 28, it slides downward relative to the triangular mounting block 21. As a result, the gear 34 inside the extrusion box 28 begins to rotate under the action of the first steel wire 39 and the first torsion spring 38, which in turn drives the telescopic block 32, which is meshed with the gear 34, to slide outward. This telescopic design reduces the floor space occupied by the extrusion box 28 and reduces the amount of dust that gets onto the bottom of the extrusion box 28 due to static electricity when it comes into contact with dust. When the telescopic block 32 returns to its original position, the tight fit between the telescopic groove 31 and the telescopic block 32 scrapes off the dust adhering to the bottom of the telescopic block 32. This design effectively reduces the amount of dust adhering to the extrusion box 28.

[0044] As the squeezing box 28 descends, the dust inside the filter element 15 falls downwards. Due to the triangular design at the top of the triangular mounting block 21, the dust slides along the outer side of the dust collection tank 11 towards the center. Through the slope design inside the dust collection tank 11, the dust first falls onto the slope and then into the dust collection box 14. If the squeezing box 28, which has the same cross-sectional dimensions as the dust collection box 14 and has no telescopic function, is located inside the dust collection box 14, the dust will fall directly onto the upper surface of the squeezing box 28 and slide upwards with the squeezing box 28, carrying the dust into the triangular mounting block 21. Therefore, to avoid the probability of dust entering the triangular mounting block 21, the squeezing box 28 is designed to be telescopic. As the squeezing box 28 descends, the telescopic block 32 slowly extends. If dust falls at this time, the dust will fall along the inner wall slope onto the top of the telescopic block 32. The dust above the telescopic block 32 will be scraped off as the telescopic block 32 is retracted. Through this design, the normal operation of the internal structure of the triangular mounting block 21 can be effectively guaranteed, and the stability of the device operation can be improved.

[0045] Example 2 is an explanation based on Example 1. For details, please refer to [link / reference]. Figures 1 to 10 The inner wall of the dust collector 11 is provided with a limiting component 5. The limiting component 5 includes a limiting gear 51 installed between the extrusion shaft 23 and the drive shaft 42. A snap-fit ​​tooth block 52 is provided above the limiting gear 51. A limiting rod 53 is fixedly connected to the top of the snap-fit ​​tooth block 52. The limiting rod 53 is slidably connected in the limiting groove 54. The limiting groove 54 is opened in the dust collector 11. A limiting plate 55 is fixedly connected to the top of the limiting rod 53. The bottom of the limiting plate 55 is connected to the pulse airflow channel 17 through a limiting spring 56.

[0046] When the pulse cleaning assembly 16 is running, high-pressure airflow enters the pulse cleaning assembly 16 through the pulse airflow channel 17. At this time, the high-pressure airflow will first cause the limiting plate 55 and the limiting rod 53 fixedly connected to it to slide downward, so that the locking tooth block 52 at the bottom of the limiting rod 53 is locked in the limiting gear 51, so that the limiting gear 51 and the squeezing shaft 23 fixedly connected to it cannot rotate. Through this design, when the pulse cleaning assembly 16 is operating, the rotation of the squeezing shaft 23 is forcibly restricted, thereby ensuring that the dust shaken off by the filter element 15 can fall completely into the dust collection box 14, avoiding the squeezing process from interfering with the dust removal process and improving the dust removal efficiency. The running time of the pulse cleaning assembly 16 can be determined according to the relative position of the squeezing box 28. When the squeezing box 28 is at the top, the pulse cleaning assembly 16 is started to run through the sensor settings. This design can further avoid the squeezing action from interfering with the dust removal process and improve the dust removal efficiency.

[0047] Example 3 is an explanation based on Example 2. For details, please refer to [link / reference]. Figures 1 to 10 A striking and shaking component 6 is provided inside the triangular mounting block 21. The striking and shaking component 6 includes a striking mounting block 61 installed inside the triangular mounting block 21. A striking groove 62 is opened inside the striking mounting block 61. A striking shaft 63 is rotatably connected inside the striking groove 62. A striking ball 64 is connected to the side wall of the striking shaft 63. A second steel wire 67 is connected to one side of the striking ball 64. A slider 610 is connected to the other end of the second steel wire 67. The slider 610 is slidably connected in the track groove 69. The track groove 69 is opened in the disc 68. The disc 68 is fixedly connected to the side wall of the extrusion shaft 23.

[0048] A second fixed shaft 65 is fixedly connected inside the striking groove 62, and the second fixed shaft 65 is connected to the striking shaft 63 through a second torsion spring 66.

[0049] The design of the impact and shaking component 6 is to periodically shake the inner wall of the triangular mounting block 21, so that the dust attached to the triangular inclined area at the top of the triangular mounting block 21 is quickly shaken off. At the same time, since the bottom of the triangular mounting block 21 is equipped with a squeezing box 28, this great vibration can also shake off some of the dust attached to the bottom of the squeezing box 28, so as to avoid the dust affecting the structure of the device and ensure the stability of the device operation.

[0050] While the extrusion shaft 23 rotates, the disc 68 fixedly connected to the side wall of the extrusion shaft 23 rotates synchronously. Since the disc 68 is provided with a track groove 69 and a slider 610, and the other end of the slider 610 is pulled by the striking ball 64 through the second steel wire 67, under normal conditions, the striking ball 64 is in contact with the inner wall of the triangular mounting block 21 under the action of the second torsion spring 66. As the slider 610 slides downward, the striking ball 64 rotates backward. When the slider 610 slides upward, the striking ball 64, under the action of the second torsion spring 66, quickly strikes the inner wall of the mounting block 21, causing the triangular mounting block 21 to vibrate. Through the connection and contact between the structures, this vibration is transmitted to all the structures in contact with the triangular mounting block 21, thereby shaking off the dust remaining on the surface of the structure. Through this continuous vibration design, the dust remaining on the internal operating parts can be further reduced, avoiding the dust from affecting the normal operation of the structure, thereby improving the stability of the device operation.

[0052] The above description is only a preferred embodiment of the present invention.
