Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, and in particular to a dust collection device for activated carbon production workshops. Background Technology

[0002] The production of activated carbon generates a large amount of dust in multiple stages, such as activation, crushing, and sieving. This dust not only severely pollutes the workshop environment, reducing visibility in the work area and affecting employees' operational vision and work efficiency, but also poses a significant threat to employees' health. Long-term inhalation of activated carbon dust may cause respiratory diseases and other health problems. Furthermore, if the dust is not effectively collected and disperses into the surrounding environment, it will also have adverse effects on the atmospheric environment.

[0003] Traditional dust control measures in activated carbon production workshops have many drawbacks. For example, some workshops rely on manual cleaning with brooms and mops, which is not only inefficient and labor-intensive but also fails to thoroughly remove dust, often missing from corners and crevices. Ordinary vacuum cleaners are ineffective at collecting fine dust and require frequent replacement of dust bags and other consumables, leading to high costs. Simple dust collection devices, such as those relying on a single filter, are prone to filter clogging, resulting in decreased suction efficiency and insufficient capacity to classify dust particles of different sizes, failing to meet the demands for efficient collection.

[0004] Therefore, we propose a dust collection device for activated carbon production workshops. Utility Model Content

[0005] The main purpose of this utility model is to provide a dust collection device for activated carbon production workshops. This device aims to prevent the large amounts of dust generated during each stage of activated carbon production from causing serious pollution to the workshop environment, affecting employee health and operational efficiency, and avoiding dust dispersion that pollutes the atmosphere. It also addresses the problems of low efficiency, high manpower consumption, poor collection effect, high cost, easy filter clogging, and insufficient graded treatment capacity in traditional dust treatment measures. This improves the dust collection efficiency and purification quality in activated carbon production workshops, reduces the harm of dust to the environment and personnel, reduces equipment maintenance costs and operational complexity, and ensures stable and orderly production. It effectively solves the problems in the background technology.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A dust collection device for an activated carbon production workshop includes a dust collection box, which has a dust collection chamber and a dust collection chamber. The dust collection chamber is located above the dust collection chamber. The dust collection chamber is located on the inner wall of the bottom end of the dust collection chamber. Two opposing first inclined plates are provided between the dust collection chamber and the dust collection chamber. A second inclined plate is provided between the two first inclined plates. A dust discharge pipe extending into the dust collection chamber is fixedly connected to the second inclined plate. A rotating shaft is rotatably connected to the inner wall of the dust discharge pipe. One end of the rotating shaft passes through the dust discharge pipe and is fixedly connected to a valve plate. A first motor is fixedly installed on the outer wall of the dust discharge pipe. The output shaft of the first motor is fixedly connected to the other end of the rotating shaft.

[0008] A first door is hinged to the front of the dust collection box and located at the dust collection chamber. Two air inlet pipes are fixedly connected to the first door, and each of the two air inlet pipes is equipped with a filter cylinder assembly.

[0009] A filter screen is fixedly installed on the rear side of the inside of the dust collection chamber. A cleaning mechanism is provided inside the dust collection chamber and in front of the filter screen. The cleaning mechanism includes a lead screw rotatably connected to the inner walls of both ends of the dust collection chamber. A second motor is fixedly installed on the outer wall of one end of the dust collection chamber. The output shaft of the second motor is fixedly connected to one end of the lead screw. A movable plate is threadedly connected to the outside of the lead screw. Cleaning brush rings for cleaning the lead screw are provided on both sides of the movable plate. The cleaning brush rings are located outside the lead screw. A sliding rod penetrating the movable plate is fixedly connected to the inner walls of both ends of the dust collection chamber. The movable plate and the sliding rod are slidably connected. A connecting plate is fixedly connected to one end of the movable plate. A scraper is fixedly connected to the end of the connecting plate away from the movable plate. One end of the scraper and one end of the connecting plate are in contact with the filter screen.

[0010] By adopting the above technical solution, the fan inside the fan box is turned on. The dust-laden airflow in the workshop enters the dust collection chamber through the air inlet pipe under the negative pressure of the fan. When the airflow is inlet, the filter screen assembly first filters the airflow and intercepts larger dust particles. As the airflow continues to flow backward, fine dust is filtered and retained when it passes through the filter screen. The purified airflow is discharged from the air outlet pipe through the fan box. When there is a lot of dust on the surface of the filter screen, the second motor is started. Its output shaft drives the lead screw to rotate. Because the moving plate is threadedly connected to the lead screw and is limited by the sliding rod, the moving plate moves along the lead screw and sliding rod. Through the connecting plate, the scraper slides on the surface of the filter screen and scrapes off the accumulated dust. The accumulated dust falls down due to gravity. At this time, the cleaning brush rings on both sides of the moving plate move synchronously. Because the cleaning brush rings are sleeved on the outside of the lead screw, their inner brushes are in continuous contact with the surface of the lead screw. As the moving plate moves, the cleaning brush rings can continuously brush away the dust and debris adhering to the lead screw, preventing dust accumulation from affecting the transmission accuracy of the lead screw, ensuring the smoothness of the threaded fit between the lead screw and the moving plate, and allowing the cleaning mechanism to operate stably and continuously clean the filter screen. Under the guidance of the first inclined plate and the second inclined plate, dust and debris gather towards the dust discharge pipe. The first motor starts, driving the rotating shaft to rotate, causing the valve plate to rotate and open. The dust falls into the dust collection box of the dust collection chamber through the dust discharge pipe. After that, the valve plate can be closed to prevent airflow from leaking backward.

[0011] Furthermore, an installation groove is provided inside the air inlet duct, and the filter cylinder assembly includes a filter cylinder installed inside the installation groove. A lifting rod is fixedly connected to the inner wall of one end of the filter cylinder, and a lifting plate is fixedly connected to the other end of the lifting rod.

[0012] By adopting the above technical solution, when the dust-laden airflow enters the air inlet duct, the filter screen first intercepts large dust particles. When cleaning / replacing is required, it can be easily removed from the mounting slot using the lifting rod or lifting plate, cleaned, and then reinstalled to maintain the filtration effect at the air inlet and avoid clogging that affects the dust collection efficiency.

[0013] Furthermore, a protective box is fixedly connected to one end of the outer wall of the dust collection box. The protective box is located outside the second motor. A second door is hinged to one side of the protective box, and a second handle is welded to one side of the outer wall of the second door.

[0014] By adopting the above technical solution, the protective box forms a physical barrier for the second motor, preventing dust and debris in the production workshop from entering the motor, reducing corrosion to the motor, and ensuring stable operation of the motor. When the second motor needs to be inspected or maintained, such as checking the motor's operating status or replacing parts, the operator can hold the second handle, pull and open the second box door to enter the protective box and carry out maintenance work on the second motor. After the work is completed, the second box door is closed, and the protective box continues to perform its protective function.

[0015] Furthermore, a fan housing is fixedly connected to the rear outer wall of the dust collection box and located at the dust collection chamber, and an air outlet duct is fixedly connected to the side of the fan housing away from the dust collection box.

[0016] By adopting the above technical solution, the fan inside the fan box provides power, and the airflow purified by the dust collection chamber enters the fan box under the suction of the fan, and is discharged from the workshop through the air outlet duct. The fan runs continuously to maintain the negative pressure inside the dust collection box, ensuring that the dust-laden airflow is continuously sucked in and treated, which is the core of the device's power.

[0017] Furthermore, a third door is hinged to the front side of the dust collection box, located in the dust collection chamber, and a third handle and a first handle are welded to the front outer walls of the third door and the first door, respectively.

[0018] By adopting the above technical solution, the first door is opened and closed by the first handle, which facilitates the maintenance of the cleaning mechanism and filter screen in the dust collection chamber; the third door is opened by the third handle, which allows the dust collection box in the dust collection chamber to be taken out and the dust to be emptied, ensuring the continuous dust collection capacity of the device.

[0019] Furthermore, locking casters are provided at the four corners of the bottom of the dust collection box.

[0020] By adopting the above technical solution, the device can be moved by unlocking the universal wheels and pushing the dust collection box to adapt to different workstations in the workshop; after the position is determined, it can be locked to avoid displacement due to work vibration and ensure that dust collection is carried out in an orderly manner.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) The dust collection device for activated carbon production workshop of this utility model achieves efficient collection and purification of dust of different particle sizes through multi-level structural design. In the initial stage of the dust-laden airflow entering the dust collection chamber, the filter screen assembly in the air inlet pipe can effectively intercept larger dust particles and initially reduce the dust content in the airflow. As the airflow flows in the dust collection chamber, under the guidance of the first and second inclined plates, the large dust particles further converge towards the dust discharge pipe. Through the opening and closing of the valve plate controlled by the first motor, the large dust particles are accurately introduced into the dust collection box in the dust collection chamber. As for fine dust, it is effectively filtered and retained when the airflow passes through the filter screen. The purified airflow is discharged from the air outlet pipe through the fan box, ensuring that the discharged gas reaches a high cleanliness standard, greatly improving the air quality of the workshop and surrounding environment, providing employees with a healthy working environment, and reducing pollution to the external environment.

[0023] (2) The dust collection device for activated carbon production workshop of this utility model is designed with the convenience of equipment maintenance in mind, thereby ensuring its stable operation. Taking the cleaning mechanism as an example, when the filter screen plate has a lot of dust on its surface and affects the filtration effect, the second motor is started, the screw rotates and drives the moving plate to move along the slide bar, and then the scraper slides on the surface of the filter screen plate through the connecting plate, efficiently scraping off the accumulated dust. During this process, the cleaning brush rings on both sides of the moving plate clean the screw at the same time, preventing dust accumulation from affecting the screw transmission accuracy, ensuring the stable operation of the cleaning mechanism, continuously cleaning the filter screen plate, extending the service life of the filter screen plate, and reducing the replacement frequency. In addition, for key components in the device, such as the protective box located outside the second motor, the dust and debris in the production workshop are effectively blocked from corroding the motor, reducing the probability of motor failure. When the second motor needs to be inspected and maintained, the operator only needs to open the second box door through the second handle to easily enter the protective box for operation, which greatly improves the equipment maintenance efficiency and ensures that the entire dust collection device can operate stably for a long time.

[0030] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0031] To prevent the large amounts of dust generated during each stage of activated carbon production from causing serious pollution to the workshop environment, affecting employee health and operational efficiency, and to avoid dust dispersion and atmospheric pollution, this method aims to address the problems of traditional dust control measures, such as low efficiency, high manpower consumption, poor collection effect, high cost, easy filter clogging, and insufficient graded treatment capacity. This will improve the dust collection efficiency and purification quality in activated carbon production workshops, reduce the harm of dust to the environment and personnel, reduce equipment maintenance costs and operational complexity, and ensure stable and orderly production. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the dust collection device for activated carbon production workshop includes a dust collection box 1, which has a dust collection chamber 2 and a dust collection chamber 3. The dust collection chamber 2 is located above the dust collection chamber 3. The bottom inner wall of the dust collection chamber 3 is provided with a dust collection box 34. Two opposing first inclined plates 4 are provided between the dust collection chamber 2 and the dust collection chamber 3. A second inclined plate 5 is provided between the two first inclined plates 4. A dust discharge pipe 6 extending into the dust collection chamber 3 is fixedly connected to the second inclined plate 5. A rotating shaft 7 is rotatably connected to the inner wall of the dust discharge pipe 6. One end of the rotating shaft 7 passes through the dust discharge pipe 6 and is fixedly connected to a valve plate 8. A first motor 9 is fixedly installed on the outer wall of the dust discharge pipe 6. The output shaft of the first motor 9 is fixedly connected to the other end of the rotating shaft 7.

[0032] A first door 16 is hinged to the front of the dust collection box 1 and located at the dust collection chamber 2. Two air inlet pipes 17 are fixedly connected to the first door 16, and a filter cylinder assembly 35 is provided in each of the two air inlet pipes 17.

[0033] A filter screen plate 22 is fixedly installed on the rear side of the inside of the dust collection chamber 2. A cleaning mechanism 10 is provided inside the dust collection chamber 2 and in front of the filter screen plate 22. The cleaning mechanism 10 includes a lead screw 11 rotatably connected to the inner walls of both ends of the dust collection chamber 2. A second motor 23 is fixedly installed on the outer wall of one end of the dust collection box 1. The output shaft of the second motor 23 is fixedly connected to one end of the lead screw 11. A moving plate 12 is threadedly connected to the outside of the lead screw 11. Cleaning brush rings 13 for cleaning the lead screw 11 are provided on both sides of the moving plate 12. The cleaning brush rings 13 are located outside the lead screw 11. A sliding rod 33 penetrating the moving plate 12 is fixedly connected to the inner walls of both ends of the dust collection chamber 2. The moving plate 12 and the sliding rod 33 are slidably connected. A connecting plate 14 is fixedly connected to one end of the moving plate 12. A scraper 15 is fixedly connected to the end of the connecting plate 14 away from the moving plate 12. One end of the scraper 15 is in contact with the filter screen plate 22.

[0034] In operation, the fan inside the fan housing 29 is turned on. Dust-laden airflow from the workshop, under the negative pressure of the fan, enters the dust collection chamber 2 through the inlet duct 17. During air intake, the filter cylinder assembly 35 first filters the airflow, intercepting larger dust particles. As the airflow continues to flow backward, fine dust particles are filtered and retained as it passes through the filter plate 22. The purified airflow is then discharged through the outlet duct 30 via the fan housing 29. When there is a significant amount of dust on the surface of the filter plate 22, the second motor 23 is started. Its output shaft drives the lead screw 11 to rotate. Because the moving plate 12 is threadedly connected to the lead screw 11 and limited by the sliding rod 33, the moving plate 12 moves along the lead screw 11 and the sliding rod 33. Through the connecting plate 14, it drives the scraper 15 to slide on the surface of the filter plate 22, scraping off the accumulated dust, which then falls due to gravity. At this time... The cleaning brush rings 13 on both sides of the moving plate 12 move synchronously. Since the cleaning brush rings 13 are sleeved on the outside of the lead screw 11, the inner brushes of the brushes are in continuous contact with the surface of the lead screw 11. As the moving plate 12 moves, the cleaning brush rings 13 can continuously brush away the dust and debris on the lead screw 11, preventing dust accumulation from affecting the transmission accuracy of the lead screw 11, ensuring the smoothness of the threaded fit between the lead screw 11 and the moving plate 12, and allowing the cleaning mechanism 10 to operate stably and continuously clean the filter screen 22. Under the guidance of the first inclined plate 4 and the second inclined plate 5, dust and debris gather towards the dust discharge pipe 6. The first motor 9 starts and drives the rotating shaft 7 to rotate, causing the valve plate 8 to rotate and open. The dust falls into the dust collection box 34 of the dust collection chamber 3 through the dust discharge pipe 6. After that, the valve plate 8 can be closed to prevent reverse leakage of airflow.

[0035] For example, such as Figure 4 As shown, the present invention also includes an installation groove 18 provided inside the air inlet duct 17, and a filter cylinder assembly 35 including a filter cylinder 19 installed inside the installation groove 18. A lifting rod 20 is fixedly connected to the inner wall of one end of the filter cylinder 19, and a lifting plate 21 is fixedly connected to the other end of the lifting rod 20.

[0036] When in use, when the dust-laden airflow enters the air inlet duct 17, the filter cylinder 19 first intercepts large dust particles. When cleaning / replacing is required, it can be easily removed from the mounting slot 18 using the lifting rod 20 and lifting plate 21. After cleaning, it can be reinstalled to maintain the filtration effect at the air inlet and avoid clogging that affects the dust collection efficiency.

[0037] For example, such as Figure 1 As shown, the present invention also includes a protective box 24 fixedly connected to one end of the outer wall of the dust collection box 1. The protective box 24 is located outside the second motor 23. A second box door 25 is hinged to one side of the protective box 24. A second handle 28 is welded to one side of the outer wall of the second box door 25.

[0038] When in use, the protective box 24 forms a physical barrier for the second motor 23, preventing dust, debris, and other contaminants from entering the motor, reducing corrosion, and ensuring stable operation. When the second motor 23 needs maintenance, such as checking its operation or replacing parts, the operator can hold the second handle 28, pull and open the second box door 25 to enter the protective box 24 and carry out maintenance work on the second motor 23. After the work is completed, the second box door 25 is closed, and the protective box 24 continues to perform its protective function.

[0039] For example, such as Figure 1 As shown, the present invention also includes a fan housing 29 fixedly connected to the rear outer wall of the dust collection box 1 and located at the dust collection chamber 2, and an air outlet duct 30 fixedly connected to the side of the fan housing 29 away from the dust collection box 1.

[0040] During use, the fan inside the fan housing 29 provides power, and the airflow purified by the dust collection chamber 2 enters the fan housing 29 under the suction of the fan, and is discharged from the workshop through the air outlet duct 30. The fan runs continuously to maintain the negative pressure inside the dust collection box 1, ensuring that the dust-laden airflow is continuously sucked in and processed, which is the core of the device's power.

[0041] For example, such as Figure 1 As shown, the present invention also includes a third door 27 hinged to the front side of the dust collection box 1 and located at the dust collection chamber 3. The front outer walls of the third door 27 and the first door 16 are respectively welded with a third handle 31 and a first handle 26.

[0042] When in use, the first door 16 is opened and closed by the first handle 26, which facilitates the inspection and maintenance of the cleaning mechanism 10, filter screen 22, etc. in the dust collection chamber 2; the third door 27 is opened by the third handle 31, which allows the dust collection chamber 3 and dust collection box 34 to be taken out and the dust to be emptied, ensuring the continuous dust collection capacity of the device.

[0043] For example, such as Figure 1As shown, the present invention also includes locking casters 32 at the four corners of the bottom of the dust collection box 1.

[0044] When in use, the device needs to be moved. The locking universal wheel 32 is released, and the dust collection box 1 can be moved to adapt to different work positions in the workshop. After the position is determined, it is locked to avoid displacement due to work vibration and to ensure that dust collection is carried out in an orderly manner.

[0045] It should be noted that this utility model is a dust collection device for activated carbon production workshops. The dust collection box 1 is moved to a suitable position in the workshop and locked using the locking casters 32. The fan inside the fan housing 29 is turned on, and the dust-laden airflow enters through the inlet pipe 17 under negative pressure. The filter cylinder 19 first intercepts large dust particles. After the airflow enters the dust collection chamber 2, the dust converges towards the dust discharge pipe 6 under the guidance of the first inclined plate 4 and the second inclined plate 5. The first motor 9 drives the valve plate 8 to open, and the dust falls into the dust collection box 34 of the dust collection chamber 3. The airflow passes through the filter plate 22, and fine dust is... After filtration and purification, the airflow is discharged from the air outlet duct 30 through the fan housing 29. When the filter screen 22 is covered with a lot of dust, the second motor 23 drives the lead screw 11 to rotate, the moving plate 12 moves along the slide bar 33, the scraper 15 scrapes off the accumulated dust, and the cleaning brush ring 13 cleans the lead screw 11 simultaneously. When cleaning or maintenance is required, the first box door 16 can be opened by the first handle 26 to operate the filter screen cylinder 19, etc., the second box door 25 can be opened by holding the second handle 28 to inspect the second motor 23, and the dust collection box 34 can be taken out and cleaned by opening the third box door 27 with the help of the third handle 31.
