Description
Technical Field
[0001] This utility model relates to the field of dust removal technology, and in particular to a dust removal device for workshops. Background Technology
[0002] During the production process in various industrial workshops, a large amount of dust is inevitably generated. This dust not only damages the production equipment in the workshop and shortens its service life, but also seriously affects the health of workshop workers, causing occupational diseases such as pneumoconiosis. At the same time, if the dust is not effectively treated, it will cause environmental pollution when emitted into the external environment.
[0003] Currently, common methods for handling dust in workshops include single cyclone dust collectors or bag filters. Cyclone dust collectors mainly rely on centrifugal force to separate dust particles, and they are effective at removing large dust particles, but their ability to handle small dust particles is limited. Bag filters intercept dust through filter bags, effectively removing small dust particles. However, in workshop environments with high humidity, dust easily absorbs moisture, causing a large amount of dust to adhere to the surface of the filter bags, resulting in bag clogging. This reduces the air permeability and cleaning efficiency of the filter bags, thus affecting the normal operation of the entire dust collection system. Utility Model Content

[0024] 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.
[0025] like Figures 1-4As shown, this utility model provides a workshop dust removal device, including a cyclone dust removal mechanism 1 and a bag filter dust removal mechanism 2. The cyclone dust removal mechanism 1 includes a cyclone separator 11, which is provided with an air inlet 12, an exhaust pipe 13, and a dust discharge port. The air inlet 12 is connected to a dust collection mechanism 3. The bag filter dust removal mechanism 2 includes a dust collector body 21, which is provided with a bag filter chamber 22 and an air inlet chamber 23. The bag filter chamber 22 is provided with a bag filter assembly 29, and the air inlet chamber... The baghouse 23 is separated from the baghouse 22 by a dust barrier plate 24. The dust barrier plate 24 is provided with a connection port that connects the baghouse 22 and the air inlet 23. A filter element 25 is provided on the connection port. A humidity detection element 26 is provided in the air inlet 23. An open mounting cavity 27 is provided on one side of the air inlet 23. A plate-shaped drying element 28 is provided in the open mounting cavity 27. The plate-shaped drying element 28 has a dry state covering the filter element 25 and a stored state stored in the open mounting cavity 27.
[0026] Specifically, the dust collection mechanism 3 is responsible for collecting dust in the workshop and transporting the dust-laden gas to the cyclone dust collector 1 for preliminary treatment. The cyclone dust collector 1 includes a cyclone separator 11, which is cylindrical with a straight section at the top and a conical section at the bottom. The height and diameter of the straight section are designed according to the processing air volume and separation efficiency. The air inlet 12 is located on the side of the cyclone separator 11. Preferably, the air inlet 12 is a tangential air inlet design, so that the dust-laden gas forms a high-speed rotating airflow after entering. The air inlet 12 is connected to the dust collection mechanism 3 through a dust collection pipe. The exhaust pipe 13 is located at the top of the cyclone separator 11 and is used to discharge the gas containing small dust particles after preliminary separation. The dust outlet is located at the bottom of the cyclone separator 11 and is used to discharge the separated large dust particles. Thus, when the dust-laden gas enters the cyclone separator 11 at a high speed along the tangential direction through the air inlet 12, a high-speed rotating airflow is formed inside the separator. Under the action of centrifugal force, large dust particles are thrown against the inner wall of the separator and slide down along the inner wall, eventually being discharged through the dust outlet. The lighter small dust particles rise with the airflow and are discharged through the exhaust pipe 13, entering the bag filter 2 for further processing. The cyclone separator 11 may also include other structures, which are existing technologies and will not be described in detail.
[0027] In this embodiment, the bag filter mechanism 2 includes a dust collector body 21. The dust collector body 21 contains a bag filter chamber 22 and an air inlet chamber 23. A bag filter assembly 29 is installed inside the bag filter chamber 22. The bag filter assembly 29 typically consists of filter bags, filter bag frames, and cleaning components. The filter bags are used to intercept small dust particles, the filter bag frames support the filter bags and prevent deformation during operation, and the cleaning device periodically removes dust accumulated on the surface of the filter bags to ensure their filtration performance. This is prior art and will not be elaborated further. The air inlet chamber 23 is separated from the bag filter chamber 22 by a dust barrier plate 24. The dust barrier plate 24 has a connection port, which connects the air inlet chamber 23 to the bag filter chamber 22. A filter element 25 is installed at the connection port, which can further filter the gas entering the bag filter chamber 22.
[0028] In this embodiment, a humidity detection device 26 is installed in the air inlet chamber 23, which can monitor the humidity of the gas entering the air inlet chamber 23 in real time. An open mounting cavity 27 is provided on one side of the air inlet chamber 23. The open mounting cavity 27 is located on the left or right side wall of the air inlet chamber 23. The plate-shaped dryer 28 is located in the open mounting cavity 27. A drive unit for driving the plate-shaped dryer 28 can also be provided in the open mounting cavity 27. Under the drive of the drive unit, the plate-shaped dryer 28 has a first working position and a second working position. When the plate-shaped dryer 28 is in the first working position, it is stored in the open mounting cavity 27. When the plate-shaped dryer 28 is in the second working position, it extends out of the open mounting cavity 27 and is in a drying state. The plate-shaped dryer 28 will cover the filter element 25. In this way, the gas in the air inlet chamber 23 is first dried by the plate-shaped dryer 28 and then transported to the filter element 25. After further filtration by the filter element 25, it is transported to the bag filter chamber 22.
[0029] In actual use, the specific operating steps are as follows:
[0030] Step 1. Dust collection stage: After the dust collection mechanism 3 is started, it collects the dust-laden gas generated in the workshop and transports it to the air inlet 12 of the cyclone dust removal mechanism 1 through the dust collection pipe.
[0031] Step 2. Cyclone Dust Removal Stage: Dust-laden gas enters the cyclone separator 11 tangentially from the inlet 12 at a high speed, forming a high-speed rotating airflow within the separator. Under the action of centrifugal force, large dust particles are thrown against the inner wall of the cyclone separator 11 and slide down along the inner wall, eventually being discharged through the dust outlet. Lighter, smaller dust particles rise with the airflow and enter the air inlet chamber 23 of the bag filter mechanism 2 through the exhaust pipe 13.
[0032] Step 3. Bag filter stage: After the dust-laden gas enters the air inlet chamber 23, the humidity detection element 26 detects the humidity of the gas in real time.
[0033] If the humidity is normal, the plate-type dryer 28 is in the stored state. The dust-laden gas first undergoes preliminary filtration through the filter element 25, and then enters the bag filter chamber 22 through the connection port. Inside the bag filter chamber 22, as the gas passes through the filter bags, small dust particles are intercepted by the filter bags, and the purified gas is discharged through the air outlet.
[0034] If the humidity detection element 26 detects high gas humidity, which may cause filter bags to become clogged, the plate-shaped dryer 28 will extend from the open mounting cavity 27, switch to a drying state, and cover the filter element 25. At this time, before entering the bag filter chamber 22, the dust-laden gas will first pass through the plate-shaped dryer 28 to reduce the humidity of the gas, and then enter the bag filter chamber 22 through the filter element 25 and the connection port for further filtration.
[0035] Step 4. Dust removal stage: During the bag filter process, as dust accumulates on the surface of the filter bag, the dust removal components will be activated periodically to remove the dust from the surface of the filter bag through pulse jet cleaning and other methods, so that the filter bag can restore its good filtration performance.
[0036] The dust removal device for workshops provided by this utility model includes a cyclone dust removal mechanism 1 and a bag dust removal mechanism 2. The cyclone dust removal mechanism 1 includes a cyclone separator 11, and the bag dust removal mechanism 2 includes a dust collector body 21. The dust collector body 21 is provided with a bag dust removal chamber 22 and an air inlet chamber 23. A bag dust removal component 29 is provided in the bag dust removal chamber 22. The air inlet chamber 23 and the bag dust removal chamber 22 are separated by a dust barrier plate 24. The dust barrier plate 24 is provided with a connection port that connects the bag dust removal chamber 22 and the air inlet chamber 23. A filter element 25 is provided on the connection port. A humidity detection element 26 is provided in the air inlet chamber 23. An open mounting cavity 27 is provided on one side of the air inlet chamber 23. A plate-shaped drying element 28 is provided in the open mounting cavity 27. By combining the cyclone dust removal mechanism 1 and the bag dust removal mechanism 2, two-stage treatment of dust is achieved, which improves the dust removal efficiency. Meanwhile, the humidity detection element 26 and plate drying element 28 in the bag filter mechanism 2 can dry the incoming gas in a timely manner according to the gas humidity, effectively avoiding the bag clogging phenomenon caused by high humidity, ensuring the air permeability and dust removal efficiency of the filter bag, enabling the entire dust removal system to operate stably and efficiently, creating a good working environment for the workshop, and reducing the harm of dust to equipment and personnel.
[0037] In this embodiment, preferably, the plate-shaped drying component 28 includes a frame 281, a drying component 282 is filled inside the frame 281, a filter screen 283 is provided on both sides of the frame 281, a sliding block 284 is provided on the frame 281, a sliding groove 271 is provided inside the open mounting cavity 27, and the sliding block 284 is slidably connected to the sliding groove 271.
[0038] The frame 281 is typically made of a sturdy and corrosion-resistant material, such as stainless steel or high-strength plastic. The frame 281 is filled with a desiccant 282, which has a large number of microporous structures to absorb moisture from the gas, thereby reducing the gas humidity. Common desiccant 282 materials with good moisture absorption properties include silica gel desiccant and activated alumina. Filters 283 are installed on both sides of the frame 281. These filters are made of fine metal mesh or fiber mesh. Their functions are twofold: firstly, they prevent the desiccant 282 from leaking out of the frame 281, ensuring the structural integrity of the plate-type desiccant 28; secondly, the filters 283 perform preliminary filtration of the gas entering the plate-type desiccant 28, blocking larger dust particles and preventing dust from entering the frame 281 and affecting the moisture absorption effect of the desiccant 282.
[0039] The open mounting cavity 27 has a sliding groove 271 inside, which extends longitudinally along the inner wall of the cavity. Its length and depth are designed according to the sliding stroke and structural dimensions of the plate-type dryer 28 to ensure smooth sliding within the cavity. A sliding block 284 is integrally formed with the frame 281 and corresponds to the sliding groove 271. The shape and size of the sliding block 284 match the sliding groove 271 within the cavity, typically being a rectangular or circular block structure with a smooth surface. This allows the plate-type dryer 28 to move flexibly within the cavity, switching between a stored state and a drying state. When drying is required for the gas entering the baghouse dust collector 22, the plate-type dryer 28 can slide along the sliding groove 271 to cover the filter element 25. When the gas humidity is normal and drying is not required, the plate-type dryer 28 can slide along the sliding groove 271 to be stored within the cavity.
[0040] In this embodiment, preferably, a drive unit is also provided in the open mounting cavity 27. The drive unit can be an electric push rod or a cylinder. The plate-shaped dryer 28 is driven by the drive unit and has a first working position and a second working position. The drive unit is connected to the humidity detection element 26 and the control system in the air inlet chamber 23. The humidity detection element 26 monitors the humidity of the gas entering the air inlet chamber 23 in real time and transmits the humidity signal to the control system. The control system judges according to the preset humidity threshold. When the humidity exceeds the threshold, the control system sends a signal to the drive unit. After receiving the signal, the drive unit starts and drives the plate-shaped dryer 28 from the first working position to the second working position covering the filter element 25. When the humidity returns to normal, the control system sends a reverse signal, and the drive unit moves to return the plate-shaped dryer 28 to the first working position. Then the plate-shaped dryer 28 is stored in the open mounting cavity 27, so the plate-shaped dryer 28 is in the stored state.
[0041] In this embodiment, preferably, a dust collection chamber 231 is provided at the bottom of the air inlet chamber 23, and the bottom of the opening mounting chamber 27 is connected to the dust collection chamber 231. The dust collection chamber 231 is provided with a dust outlet. A conical plate is provided at the bottom of the air inlet chamber 23, and a dust collection port is provided at the bottom of the conical plate. The dust collection port is connected to the dust collection chamber 231, and a control valve is also provided on the dust collection port to control its opening or closing. The dust outlet is located at the bottom of the dust collection chamber 231 and is usually a circular or square opening for connecting an external dust collection device, such as a dust collection bin or a screw conveyor.
[0042] In this embodiment, preferably, the sliding groove 271 is provided with a plurality of arc-shaped groove portions 272, which are arranged sequentially at intervals along the length direction of the sliding groove 271. Each arc-shaped groove portion 272 is semi-circular or semi-circular in shape. The depth or width of the arc-shaped groove is set according to the size of the sliding block 284. The sliding block 284 slides along the sliding groove 271 and will intermittently slide into the arc-shaped groove, which can make the frame 281 sway up and down.
[0043] Furthermore, a strip-shaped mounting groove is provided at the end of the frame 281. The driving end of the driving unit is movably connected in the strip-shaped mounting groove, that is, the driving end of the driving unit is slidably connected in the strip-shaped groove. The driving end can move up and down in the strip-shaped groove, but the driving end cannot move in the horizontal direction of the strip-shaped groove. Thus, under the action of the driving unit, the plate-shaped drying component 28 can be driven to reciprocate along the direction of the open mounting cavity 27. During the movement of the plate-shaped drying component 28 along the open mounting cavity 27, the sliding block 284 reciprocates along the length direction of the sliding groove 271. When the sliding block 284 passes through the arc-shaped groove 272, due to the guiding restriction of the groove, the frame 281 can drive the plate-shaped drying component 28 to shake up and down. This setting has the following effects: First, for the drying component 282 filled inside the plate-shaped drying component 28, the shaking can make the drying component 282 continuously roll and mix in the frame 281, preventing the drying component 282 from clumping or unevenly distributed due to long-term stillness, and always maintaining good moisture absorption performance. Secondly, the dust adhering to the surface of the plate-type dryer 28, including the filter screen 283 and the frame 281, is more easily dislodged during shaking, reducing the impact of dust on the air permeability of the plate-type dryer 28 and improving the working efficiency and service life of the plate-type dryer 28.
[0044] 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.
