Technical Field

[0001] This utility model relates to the field of environmental protection and dust removal technology, and in particular to a dust collection device with a valved air box. Background Technology

[0002] Cement is one of the most widely used building materials in the world. Cement plants sell cement in bulk and bagged form. Currently, bagged cement is mainly loaded manually or by special machinery, although robotic loading is also used. During the bagging and transportation of cement, cement dust is easily dispersed, which not only pollutes the environment but may also harm the health of the workers.

[0003] To reduce dust spillage, many cement plants have equipped their loading areas with industrial dust collection equipment, of which the bellows structure is a key component. Existing bellows structures primarily use negative pressure suction to concentrate dust generated during loading and draw it into the dust collection equipment. Current valved bellows structures are widely used in industrial settings with severe dust pollution, such as cement plants. However, in practical applications, these bellows structures still have technical limitations, such as uneven dust collection and severe dust accumulation.

[0004] Based on the above problems, we propose a dust collection device with a valved air box to achieve the effects of environmental protection, intelligent structure, high efficiency and wide applicability. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a dust collection device with a valved air box to solve the problems of uneven dust collection effect and serious dust accumulation in the existing industrial dust removal equipment.

[0007] All the valved air boxes are arranged side by side and sealed together in sequence. Each valved air box includes a box body, a guide plate and a valve assembly. The guide plate is located at the lower end of the box body and the valve assembly is installed on the side of the guide plate. The valve assembly is used to control and adjust the opening and closing degree of the guide plate.

[0008] Each of the dust collection plates corresponds to a box and is located at the lower end of the box. The dust collection plates are used to assist in collecting dust.

[0009] The dust removal duct is used to guide the absorbed dust into the valved air box and the external dust removal device.

[0010] Preferably, each of the boxes has a sealing plate at both ends, and adjacent sealing plates are connected by flanges, so that all the boxes are interconnected.

[0011] Preferably, the valve assembly is a pneumatic butterfly valve, and the rotating shaft of the pneumatic butterfly valve passes through the guide plate.

[0012] Preferably, each of the dust collection plates is inclined, and the middle of each dust collection plate is concave downward.

[0013] Preferably, the dust removal pipeline includes a main pipeline and several bends;

[0014] One end of the main pipe is connected to the side wall of the outermost housing, and the other end of the main pipe is connected to the external dust removal equipment.

[0015] Preferably, each of the two ends of the bend is connected to the lower end of a box and a dust collection plate, respectively, and the radius of curvature of the bend is 0.4-0.6m.

[0016] Preferably, the upper end of the box is provided with a mounting bracket for mounting the box on the side wall or top of the wall.

[0017] As described above, the dust collection device with a valved air box disclosed in this utility model has the following beneficial effects: This utility model achieves efficient dust collection through the coordinated structure of a valved air box, a dust collection plate, and an air duct.

[0028] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0029] Please see Figures 1 to 5 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance.

[0030] like Figure 1-3 As shown, this utility model provides a dust collection device with valved air boxes, including: a plurality of valved air boxes 1, a plurality of dust collection plates 2, and a dust removal pipe 3; the valved air boxes 1 are used to absorb dust and control the airflow of each dust collection channel, the dust collection plates 2 cooperate with the valved air boxes 1 to collect dust generated by the dust collection source, and the dust removal pipe 3 is used to pour the absorbed dust into the valved air boxes 1 and external dust removal equipment.

[0031] All valved air boxes 1 are arranged side by side and sequentially sealed and connected. The number of valved air boxes 1 is determined based on the actual amount of dust generated during the loading of cement bags on site, ensuring a compact structure. Each valved air box 1 includes a box body 10, a baffle plate 11, and a valve assembly 12. The baffle plate 11 is located at the lower end of the box body 10, and the valve assembly 12 is installed on the side of the baffle plate 11. The valve assembly 12 is used to control and adjust the opening and closing degree of the baffle plate 11. The end of the box body 10 is connected to the main duct 30 of the dust collector, and the other end of the main duct 30 is connected to the central dust collection system. The negative pressure generated by the fan of the central dust collection system draws dust into the box body 10. When the valve assembly 12 is open, the dust enters the box body 10 through the suction port of the baffle plate 11 under the action of negative pressure. The baffle plate 11 is designed with an inclination to facilitate the smooth entry of dust into the box body 10 under negative pressure. The surface of the baffle plate 11 is smooth to reduce dust adhesion and ensure dust collection efficiency. The valve assembly 12 is installed on the side of the guide plate 11 and is used to control the opening and closing degree of the guide plate 11. By adjusting the opening and closing degree of the valve assembly 12, the area of ​​the suction port can be adjusted, thereby controlling the suction air volume and suction effect.

[0032] Each dust collection plate 2 corresponds to a box 10 and is located at the lower end of the box 10. The dust collection plate 2 is used to assist in collecting dust. The dust collection plate 2 is detachably connected to the box 10 for maintenance and cleaning.

[0033] The dust collection duct 3 is used to guide the absorbed dust into the valved air box 1 and the external dust collection device.

[0034] In one embodiment, please refer to Figure 1-2 Each enclosure 10 has a sealing plate 13 at both ends. Adjacent sealing plates 13 are connected by flanges, and a sealing gasket is placed between the two connecting flanges to provide a seal and prevent gas leakage. All enclosures 10 are interconnected. Adjacent sealing plates 13 are connected by flanges, and the surface of the sealing plates 13 is provided with a sealing film to prevent gas leakage and improve the airtightness when multiple valved air boxes 1 are used together.

[0035] In one embodiment, please refer to Figure 3 Valve assembly 12 is a pneumatic butterfly valve, with its rotating shaft passing through the guide plate 11. When the pneumatic actuator drives the rotating shaft to rotate, the guide plate 11 rotates along with the shaft. The valve plate is fixed on the rotating shaft, and the opening and closing angle of the valve plate is controlled by the rotation of the shaft. The pneumatic butterfly valve controls and adjusts the opening and closing degree of the guide plate 11 to control the opening and closing state of each dust suction port and the air volume, thereby adjusting the dust suction effect.

[0036] In one embodiment, please refer to Figure 2 Each dust collection plate 2 is inclined, and the middle of each dust collection plate 2 is concave. The dust collection plate 2 can collect dust by being concave, making it easy to clean.

[0037] In one embodiment, please refer to Figure 2 and Figure 5 The dust removal pipe 3 includes a main pipe 30 and several bends 31.

[0038] One end of the main pipe 30 is connected to the side wall of the outermost housing 10, and the other end is connected to the external dust collection equipment. The main pipe 30 is still connected to the side wall of the outermost housing 10 via a flange to ensure airtightness. With multiple dust inlets and one dust outlet pipe, the dust outlets of all valved air boxes 1 are connected to the central dust collection equipment via the main pipe 30, avoiding the complex piping layout problems caused by independent dust discharge from each valved air box 1, while improving dust handling efficiency. By setting multiple inlets, negative pressure can be generated at various locations within the dust collection plate 2 to draw in dust, increasing the dust suction speed, resulting in a compact layout and small footprint. External dust collection equipment includes high-pressure fans and dust handling equipment of different models, depending on the needs of each factory. For example, high-pressure fans can be selected from series such as the 9-26 high-pressure centrifugal fan, suitable for highly abrasive dust environments such as cement plants. Alternatively, PPC-type pulse jet bag filters can be used, employing a pulse cleaning system for good cleaning effect and stable operation. This is existing technology and will not be elaborated upon here. The main duct 30 penetrates the factory ceiling, allowing high-pressure fans and dust handling equipment to be installed outside the factory, isolated from the production area. This protects the long-term normal operation of the dust collection equipment and reduces its environmental impact on the production area.

[0039] In one embodiment, please refer to Figure 2 Each bend 31 is connected at both ends to the lower end of a housing 10 and a dust collection plate 2, and the radius of curvature of the bend 31 is between 0.4 and 0.6 m. The moderate curvature of the bend 31 can effectively guide the airflow and support the dust collection plate 2. The dust collection plate 2 and the bend 31 are detachably connected for easy maintenance and cleaning.

[0040] In one embodiment, please refer to Figure 4 The upper end of the housing 10 is provided with a mounting bracket 4, which is used to install the housing 10 on the side wall or ceiling 5. The mounting bracket 4 is customized according to the factory structure on site, and is used to install the entire equipment on the upper side wall of the factory to save space. When loading is carried out on one side of the loading line, the dust collection plate 2 on the corresponding side starts to work, and most of the dust is sucked away and treated by the dust collector with the airflow.

[0041] The specific usage process of this utility model is as follows: The equipment is installed in the area where cement bags fall and stack or at the end of the conveyor. When in use, the guide plate 11 is opened and the valve assembly 12 is opened. The valve assembly 12 controls and adjusts the opening and closing degree of different guide plates 11 according to different dust emission points. When some of the valved air boxes 1 are working, the remaining air vents can be selected to be completely closed or operate in a low-power mode as needed. When not in operation, the state of the guide plate 11 is linked to the operating mode of the air vents. It can be completely closed to prevent dust from entering the non-working area, or it can be adjusted to a certain opening and closing angle to handle residual dust and prevent dust retention. The collected dust is transported to the central dust removal system through the main pipeline 30. After the dust removal system filters and separates the dust, it discharges clean air and recovers or centrally processes the collected dust.

[0042] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
