Description

Technical Field

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

[0002] In industrial production, construction, mining and other working environments, a certain amount of dust pollutants are generated. This dust not only pollutes the surrounding environment and affects the processing precision of products, but may also be inhaled by workers, endangering their respiratory health. Long-term accumulation also poses safety hazards such as dust explosions. Dust collection devices, as components of dust control, can capture and separate dust particles in the air, achieving air purification and dust recovery.

[0003] Existing dust collection equipment typically includes a collection box, a negative pressure fan, a filter screen, and a discharge port. The collection box provides a closed space for dust separation and storage. The negative pressure fan is installed on one side or top of the box and draws dust-laden air into the device by generating negative pressure suction. The filter screen is fixed in the inner cavity of the box and serves as a dust separation component. Its pore size is adapted to the particle size requirements of the dust to be separated. During operation, the negative pressure fan starts to generate negative pressure. After the dust-laden air is drawn into the collection box, it passes through the filter screen. The dust particles are trapped by the filter screen, and the filtered clean air is discharged from the box, thus achieving the separation of dust and air.

[0004] However, when dust-laden air enters the collection chamber under negative pressure, the airflow directly impacts the filter surface without a buffering or deceleration process. This causes larger dust particles in the air to adhere directly to the filter surface, accelerating clogging, reducing filtration efficiency, and potentially causing filter damage due to the impact and abrasion of large dust particles, thus affecting dust separation. Therefore, it is necessary to provide a dust collection device for dust removal equipment to solve the above problems. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a dust collection device for dust removal equipment. This device solves the problem that when dusty air enters the collection box under negative pressure, the airflow directly impacts the filter screen, causing large dust particles to quickly adhere and clog the filter screen, and wear down the filter screen, thereby reducing the filtration efficiency and dust separation effect.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is a dust collection device for dust removal equipment, comprising:

[0007] A dust collection box, wherein an assembly rack is installed inside the dust collection box;

[0008] A turbulence-collecting dust collection assembly is mounted on the assembly frame. The turbulence-collecting dust collection assembly includes a first intermediate plate and a second intermediate plate respectively mounted on the assembly frame. It is suitable for diverting dust-laden air. A first turbulence plate is mounted on the first intermediate plate, and a second turbulence plate is mounted on the second intermediate plate. The first turbulence plate and the second turbulence plate are staggered to make the dust-laden airflow turn multiple times and separate large dust particles.

[0009] Furthermore, the assembly frame is provided with ventilation holes, and the first intermediate plate and the second intermediate plate are installed in the ventilation holes.

[0010] Furthermore, the first intermediate plate and the second intermediate plate are located in the ventilation holes and are distributed at intervals.

[0011] Furthermore, the assembly rack is provided with an assembly slot, and the ventilation hole is provided with a dust collection hole that communicates with the assembly slot.

[0012] Furthermore, a dust collection box slides within the assembly slot, and an arc-shaped dust collection plate is installed inside the dust collection box.

[0013] Furthermore, a first handle is installed on the dust collection box, and the first handle has anti-slip texture.

[0014] Furthermore, a filter plate is installed inside the dust collection box, a protective net is installed at the air inlet of the dust collection box, and a dust collection fan is installed at the air intake of the dust collection box.

[0015] By adopting the above technical solution, this utility model has the following beneficial effects: The dust collection device for dust removal equipment provided in this application, through the staggered distribution design of the first baffle and the second baffle, causes the dust-laden airflow to turn multiple times and separate large dust particles, effectively reducing the impact and adhesion of large dust particles on the filter plate, delaying filter plate clogging, reducing wear and extending the service life of the filter plate.

[0025] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0026] like Figures 1-3 As shown, this application provides a dust collection device for dust removal equipment, including a dust collection box 1. A filter plate 11 is bolted to one end inside the dust collection box 1. The filter plate 11 is a prior art device and serves as the filtration unit of the device, responsible for intercepting fine dust. When the dust-laden air that has undergone pretreatment at the front end flows through this part, the remaining fine dust particles are effectively intercepted by the filter plate 11, allowing only clean air to pass through, thereby ensuring the cleanliness of the exhaust gas. The filter plate 11 is installed by bolts, which not only ensures its installation stability under airflow impact and equipment vibration environments, but also provides convenience for later maintenance. The staff can easily disassemble, clean or replace the filter plate 11 according to its wear and tear, ensuring that the device always maintains stable filtration performance.

[0027] A protective net 12 is installed at the air inlet at the other end of the dust collection box 1. The protective net 12 serves as a protective barrier for the device and is mainly used to intercept large impurities such as gravel, metal shavings, and packaging bag fragments that may be mixed into the dusty airflow in the working environment. This prevents such impurities from entering the dust collection box 1 and colliding and rubbing against subsequent functional components, causing damage, deformation, or jamming of the components. At the same time, the structural design of the protective net 12 will not significantly obstruct the flow of dusty air, ensuring that the airflow can smoothly enter the device for processing. Support legs 13 are installed at the lower end of the dust collection box 1 by bolts. The support legs 13 are installed in a symmetrical manner to support the entire dust collection box 1 on the ground.

[0028] like Figures 3-5 As shown, a vacuum cleaner 2 is bolted to the air intake at one end of the vacuum chamber 1. The vacuum cleaner 2 is connected to an external power source and can be started by the corresponding control button. It can form a stable and continuous negative pressure environment inside the vacuum chamber 1. The suction force generated by the negative pressure will continuously draw the dust-laden air in the working area into the vacuum chamber 1, providing sufficient airflow power for the subsequent dust separation and collection process.

[0029] An assembly frame 3 is bolted inside the dust collection box 1. The assembly frame 3 serves as the mounting carrier for the turbulent dust collection part and is located between the air inlet of the dust collection box 1 and the filter plate 11. This ensures that the dust-laden air can pass through the initial interception of the protective net 12, the assembly frame 3, and the pretreatment of the turbulent dust collection part in sequence, achieving a graded filtration effect. Multiple sets of ventilation holes 31 are opened on the assembly frame 3. The distribution of the ventilation holes 31 ensures that the dust-laden air can be evenly distributed after entering the assembly frame 3, so that each set of ventilation holes 31 can be allocated a relatively balanced airflow, preventing the local processing load from being too large due to uneven airflow distribution, which would affect the overall pretreatment effect.

[0030] Multiple sets of assembly slots 32 are provided on one side of the assembly frame 3, and a dust collection hole 33 communicating with the assembly slots 32 is provided on the bottom surface of the ventilation hole 31.

[0031] like Figures 4-7 As shown, a turbulent dust collection component 4 is installed on the assembly frame 3. This turbulent dust collection component 4 changes the flow state of the dust-laden airflow, amplifies the difference in movement between dust particles and airflow, thereby achieving the separation of large dust particles from the airflow, reducing the direct impact and adhesion of large dust particles on the subsequent filter plate 11, extending the service life of the filter plate 11, reducing the clogging rate of the filter plate 11, and thus improving the long-term operating efficiency of the entire device.

[0032] The turbulence dust collection assembly 4 includes multiple sets of first intermediate plates 41 and second intermediate plates 43, which are respectively fixedly installed on the ventilation holes 31. The first intermediate plates 41 and second intermediate plates 43 serve as the mounting base for the turbulence plate. The fixing method must ensure sufficient connection strength to resist the continuous impact of dust-laden airflow and the vibration during equipment operation, and prevent the turbulence plate from shifting due to loose fixing, thus affecting the turbulence effect. The two sets of intermediate plates are distributed at intervals in the ventilation holes 31 to form a multi-layer turbulence plane, so that the dust-laden airflow can encounter the turbulence structure multiple times during the process of passing through the ventilation holes 31, providing sufficient time for dust separation.

[0033] Multiple sets of first baffles 42 are fixedly installed on the first intermediate plate 41. When the dust-laden airflow enters the ventilation hole 31 at a certain speed and comes into contact with the first baffles 42, the airflow will be forcibly turned under the obstruction of the baffles. The large dust particles carried in the airflow have large inertia and are difficult to change their direction of movement quickly with the airflow. They will continue to maintain their original movement trend and collide with the first baffles 42 or deviate from the mainstream airflow trajectory, thus achieving preliminary dust separation. The arrangement of multiple sets of first baffles 42 ensures that the airflow can be evenly stressed, avoids abnormal local airflow speed, and ensures that every airflow can be effectively turbulent. Multiple sets of second baffles 44 are fixedly installed on the second intermediate plate 43. The second baffles 44 cooperate with the first baffles 42 to jointly construct a complex interlaced turbulence channel.

[0034] The multiple sets of first intermediate plates 41 and second intermediate plates 43 are spaced apart, and the multiple sets of first baffles 42 and second baffles 44 are staggered. Specifically, after the dust-laden airflow passes through the first baffle 42 for the first time and just completes the change of direction, it will meet the staggered second baffles 44 and be forced to change its flow direction again. During this process, the inertia of the dust particles is further enhanced, improving the separation effect between them and the airflow. After multiple staggered baffles, most of the large dust particles can be separated from the airflow and settle down to the dust collection hole 33 on the bottom surface of the ventilation hole 31 under the action of gravity.

[0035] A dust collection box 45 is slidably installed inside the assembly slot 32. As a special storage container for large dust particles, the dust collection box 45 needs to have a certain dust storage capacity to accommodate large dust particles separated within a certain period, thus reducing the frequency of cleaning. The dust collection box 45 adopts a sliding installation structure, forming a sliding fit with the assembly slot 32. The staff can directly pull out the dust collection box 45 for cleaning without disassembling other parts of the device, which improves the convenience and efficiency of maintenance operations.

[0036] A first handle 451 is fixedly installed on the outer wall of one end of the dust collection box 45. The first handle 451 provides a convenient point of force for the operator to pull the dust collection box 45. Multiple sets of arc-shaped dust collection plates 46 are fixedly installed on the inner bottom of the dust collection box 45. The multiple sets of arc-shaped dust collection plates 46 are located inside the dust collection box 45 and are distributed at intervals. The arc-shaped dust collection plates 46 are auxiliary structures to improve the storage effect of the dust collection box 45. Their arc-shaped structure can guide the dust particles falling into the dust collection box 45 to gather at the bottom, preventing the dust from being dispersed and accumulated inside the dust collection box 45. At the same time, the design of the interval distribution can form multiple independent dust collection areas, effectively preventing the dust from being stirred up again by airflow disturbance and re-mixed into the airflow inside the device.

[0037] A sealing gasket 47 is fixedly installed on the outer wall of one end of the dust collection box 45. The sealing gasket 47 cooperates with the assembly frame 3 and fills the gap between the dust collection box 45 and the assembly frame 3. When the dust collection box 45 is fully installed in the assembly slot 32, the sealing gasket 47 will be tightly attached to the corresponding contact surface of the assembly frame 3 under the squeezing action of the dust collection box 45, blocking the airflow channel and preventing the dust-laden airflow from bypassing the turbulent dust collection assembly 4 through the gap and flowing directly to the filter plate 11.

[0038] An operating door 48 is hinged to one side of the dust collection box 1. When closed, the operating door 48 is tightly sealed to the dust collection box 1, ensuring the airtightness of the dust collection box 1 and preventing airflow leakage from the door gaps, which would affect the stability of the negative pressure environment and the dust removal effect. The position of the operating door 48 ensures that after opening the operating door 48, the operator can directly access the dust collection box 45. The dust collection box can be pulled out and cleaned without additional equipment adjustments or tools, improving maintenance convenience. A second handle 481 is fixedly installed on the side wall of the operating door 48. The second handle 481 provides a convenient force point for the operator to open and close the operating door 48. When the operator pulls the second handle 481 to open the operating door 48, they can directly operate the dust collection box 45, pull out the dust collection box 45 to clean the large dust particles inside, and after cleaning, reinsert the dust collection box 45 into the assembly slot 32, ensuring that the sealing gasket 47 and the assembly frame 3 are tightly fitted. Then close the operating door 48 to restore the normal operation of the device.

[0039] The working principle of this utility model is as follows: When the device is started, the vacuum fan 2 starts to run, forming a stable negative pressure environment inside the vacuum box 1. The suction force generated by this negative pressure environment will act on the working area, drawing dust-laden air into the device from the air inlet of the vacuum box 1. The dust-laden air first passes through the protective net 12 at the air inlet. The protective net 12 intercepts large impurities mixed in, preventing impurities from entering the subsequent processing stage and causing damage to the components. The dust-laden air that has been initially intercepted continues to flow into the vacuum box 1 and enters the ventilation hole 31 of the assembly frame 3.

[0040] The dust-laden airflow entering the ventilation hole 31 will come into contact with the first baffle 42 and the second baffle 44 of the turbulence dust collection assembly 4 in sequence. Since the first baffle 42 and the second baffle 44 are staggered, the airflow will be forced to change its flow direction multiple times during the process. During this process, the large dust particles carried in the airflow are not easy to turn quickly with the airflow due to inertia. They will collide with the baffle or break away from the airflow trajectory. Under the action of gravity, they will settle down to the dust collection hole 33 on the bottom surface of the ventilation hole 31, and then fall into the corresponding dust collection box 45 below through the dust collection hole 33.

[0041] After being pretreated by the turbulent dust collection component 4, most of the large dust particles in the dust-laden air have been removed. At this time, the airflow continues to flow into the filter plate 11 inside the dust collection box 1. The filter plate 11 filters the dust particles remaining in the airflow and intercepts the dust particles on one side of the filter plate 11. The filtered clean air then passes through the filter plate 11 and is discharged from the air outlet of the device under the action of the dust collection fan 2, thus achieving the effect of air purification.
