Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the field of dust removal device technology, and more specifically, to a spray dust removal device for red mud conveying. Background Technology
[0002] After alumina ore undergoes leaching and separation sedimentation processes, red mud slurry is obtained. This slurry is then filtered to obtain red mud material with reduced water content. This red mud material is stored dry to minimize pollution of the storage area by the red mud adhering liquid. Because the red mud material undergoes filtration before being transferred to the storage area, its water content is significantly reduced, making its surface prone to cracking. Consequently, during prolonged transport within the production workshop, dust easily rises from the surface of the red mud material, severely impacting the air quality and threatening the health of workshop workers. Currently, an electrostatic adsorption dust removal method has been proposed to address the dust problem of dry red mud material; however, this method is costly in terms of electricity consumption and difficult subsequent processing, hindering cost reduction and efficiency improvement for enterprises. Utility Model Content
[0003] To overcome the above-mentioned defects, the embodiments of this disclosure provide a spray dust removal device for red mud transportation, which solves the technical problems of high power consumption and high difficulty in subsequent treatment of electrostatic adsorption dust removal methods in related technologies, which are not conducive to enterprises reducing costs and increasing efficiency.

[0005] A protective cover is provided to cover the periphery of the conveyor belt. The protective cover has a feed inlet located above the beginning of the conveyor belt.
[0006] A water supply pipe is installed inside the protective cover and above the conveyor belt. The length direction of the water supply pipe is the same as the conveying direction of the conveyor belt. The water supply pipe is used to connect to a water source.
[0007] A nozzle is provided on the water supply pipe, the inlet of the nozzle is connected to the water supply pipe, the outlet of the nozzle faces the conveyor belt located below it, and there are multiple nozzles, all of which are arranged along the length of the water supply pipe.
[0008] For example, in the spray dust removal device for red mud conveying provided in at least one embodiment of this disclosure, there are water pipes on both sides of the conveyor belt, and each water pipe is provided with a plurality of nozzles along its length.
[0009] For example, in at least one embodiment of the spray dust removal device for red mud conveying provided in this disclosure, the spray dust removal device for red mud conveying further includes:
[0010] A dust sensor is mounted on the protective cover and located on one side of the nozzle. There are multiple dust sensors, and each dust sensor is arranged in a one-to-one correspondence with a nozzle.
[0011] An electric regulating valve is connected between the nozzle and the water supply pipe, and the electric regulating valve is connected to the nozzle in a one-to-one correspondence.
[0012] The control module has its input terminal electrically connected to the dust sensor and its output terminal electrically connected to the electric regulating valve.
[0013] For example, in at least one embodiment of the spray dust removal device for red mud conveying provided in this disclosure, the spray dust removal device for red mud conveying further includes:
[0014] A booster pump, one end of which is connected to the water supply pipe, and the other end of which is connected to the water source; the controlled end of the booster pump is electrically connected to the control module.
[0015] A main valve is connected between the booster pump and the water supply pipe, and the controlled end of the main valve is electrically connected to the control module.
[0016] For example, in at least one embodiment of the present disclosure, the spray dust removal device for transporting red mud further includes a protective box, which is disposed inside the protective cover, and the control module and the pressurizing pump are both disposed inside the protective box.
[0017] For example, in at least one embodiment of the spray dust removal device for red mud conveying provided in this disclosure, the spray dust removal device for red mud conveying further includes a guide plate. The guide plate is disposed inside the protective cover and located between the conveyor belt and the feed inlet. The upper end of the guide plate is connected to the protective cover, and the connection point is located on the side of the feed inlet away from the end of the conveyor belt. The lower end of the guide plate is inclined towards the end of the conveyor belt, and the connection point is located between the end of the conveyor belt and the feed inlet.
[0018] For example, in at least one embodiment of the present disclosure, the spray dust removal device for red mud transportation further includes a support member located below the guide plate. One end of the support member is connected to the protective cover, and the other end of the support member contacts the lower side of the guide plate.
[0019] For example, in at least one embodiment of the spray dust removal device for red mud conveying provided in this disclosure, the upper end of the guide plate has an overlap edge, and the protective cover includes:
[0020] A cylindrical body is located around the conveyor belt. The upper end face of the cylindrical body has a receiving groove. The overlapping edge is inserted into the receiving groove. The water supply pipe is disposed inside the cylindrical body.
[0021] A cover plate is disposed on the upper end of the cylinder, and the cover plate is detachably connected to the cylinder. The upper end face of the overlapping edge contacts the lower end face of the cover plate.
[0022] For example, in the spray dust removal device for red mud conveying provided in at least one embodiment of this disclosure, the inner wall of the cylinder has a vertical dovetail groove, the upper end of the vertical dovetail groove is connected to the receiving groove, the lower end of the vertical dovetail groove is closed, the end of the support member has a dovetail strip, and the dovetail strip is inserted into the vertical dovetail groove.

[0024] The beneficial effects of the embodiments disclosed herein are as follows: the protective cover is installed around the conveyor belt, and the feed inlet is located above the beginning of the conveyor belt. During the transportation of red mud, the protective cover can play a physical isolation role, confining the red mud in a relatively closed space and reducing the spread of red mud dust to the large space of the workshop. This can initially control the large-scale dispersion of dust, so that subsequent processing can be concentrated in the smaller area inside the protective cover.
[0025] The water supply pipe is positioned above the conveyor belt and runs along the same direction as the conveyor belt. The pipe is connected to a water source to provide water for the spraying. Multiple nozzles are arranged along the length of the water supply pipe, with their inlets connected to the pipe and their outlets facing the conveyor belt. When the red mud material is transported on the conveyor belt, the water in the pipe is sprayed out in a mist form through the nozzles. These mist droplets have a large specific surface area, allowing them to fully contact the suspended red mud dust particles in the air. On one hand, the water droplets adhere to the surface of the dust particles, causing them to settle due to gravity and no longer float in the air. On the other hand, the fine droplets collide and agglomerate with the airborne red mud dust as they fall, gradually forming larger particle clusters. These clusters, being heavier, are more easily affected by gravity and settle to the bottom of the conveyor belt or protective cover, thus reducing the concentration of red mud dust in the air and suppressing dust.
[0026] The protective cover, in conjunction with the water supply pipe and nozzles, effectively reduces dust generation during the transport of red mud materials on the workshop conveyor belt, significantly improving air quality and reducing the health threat of dust to production personnel, thus creating a relatively clean production environment. Compared to the previously proposed electrostatic adsorption dust removal method, this spray dust removal device has a simpler structure and does not require a complex electrostatic generation and control system, greatly reducing equipment purchase costs and operating electricity costs. Furthermore, subsequent maintenance mainly focuses on simple operations such as ensuring the water supply pipes are unobstructed and cleaning the nozzles, reducing the difficulty of subsequent processing and helping enterprises achieve cost reduction and efficiency improvement goals, thereby enhancing their economic benefits.

[0038] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0039] like Figures 1-2As shown, a spray dust removal device for red mud conveying according to an embodiment of the present disclosure is provided for installation around a conveyor belt 18. The device includes a protective cover 1, a water pipe 2, and nozzles 3. The protective cover 1 is used to cover the outer periphery of the conveyor belt 18 and has a feed inlet 4 located above the beginning of the conveyor belt 18. The water pipe 2 is installed inside the protective cover 1 and above the conveyor belt 18. The length direction of the water pipe 2 is the same as the conveying direction of the conveyor belt 18, and the water pipe 2 is used to communicate with a water source. The nozzles 3 are installed on the water pipe 2. The inlet of the nozzle 3 is connected to the water pipe 2, and the outlet of the nozzle 3 faces the conveyor belt 18 located below it. There are multiple nozzles 3, and all the nozzles 3 are arranged along the length direction of the water pipe 2.
[0040] For example, such as Figure 1 and Figure 2 As shown, the protective cover 1 is installed around the conveyor belt 18, and the feed inlet 4 is located above the beginning of the conveyor belt 18. During the transportation of red mud, the protective cover 1 can play a physical isolation role, confining the red mud in a relatively closed space and reducing the spread of red mud dust to the large space of the workshop. This can initially control the large-scale dispersion of dust, so that subsequent processing can be concentrated in the smaller area inside the protective cover 1.
[0041] A water supply pipe 2 is positioned above the conveyor belt 18 and its length is parallel to the conveying direction of the conveyor belt 18. The water supply pipe 2 is connected to a water source to provide water for spraying. Multiple nozzles 3 are arranged along the length of the water supply pipe 2. The inlets of the nozzles 3 are connected to the water supply pipe 2, and their outlets face the conveyor belt 18. When the red mud material is transported on the conveyor belt 18, the water in the water supply pipe 2 is sprayed out in a mist form through the nozzles 3. The mist droplets have a large specific surface area, allowing them to fully contact the red mud dust particles suspended in the air. On the one hand, the water droplets adhere to the surface of the dust particles, causing them to settle due to gravity and no longer float in the air. On the other hand, the fine droplets collide and agglomerate with the flying red mud dust during their descent, causing the dust particles to gradually gather into larger particle clusters. These particle clusters are heavier and more easily affected by gravity, settling to the bottom of the conveyor belt 18 or the protective cover 1, thereby reducing the concentration of red mud dust in the air and suppressing dust.
[0042] The protective cover 1, in conjunction with the water supply pipe 2 and nozzle 3, effectively reduces dust generation during the transport of red mud material on the conveyor belt 18 in the workshop, significantly improving air quality and reducing the health threat of dust to production personnel, thus creating a relatively clean production environment. Compared to the previously proposed electrostatic adsorption dust removal method, this spray dust removal device has a relatively simple structure and does not require a complex electrostatic generation and control system, which can greatly reduce equipment purchase costs and power consumption costs during operation. Furthermore, subsequent maintenance mainly focuses on simple operations such as ensuring the water supply pipe 2 is unobstructed and cleaning the nozzle 3, reducing the difficulty of subsequent processing and helping enterprises achieve cost reduction and efficiency improvement goals, thereby enhancing their economic benefits.
[0043] The device is directly installed around the conveyor belt 18 and is closely integrated with the red mud conveying process. It does not affect the normal transfer process of red mud, is easy to install and integrate into the existing red mud conveying production line, and does not require large-scale modification of the production line. It has strong practicality and operability, and can be quickly promoted and applied to relevant red mud treatment workshops to solve the dust problem.
[0044] In some examples, there are water pipes 2 on both sides of the conveyor belt 18, and each water pipe 2 has multiple nozzles 3 arranged along its length.
[0045] For example, such as Figure 1 and Figure 2 As shown, water pipes 2 and nozzles 3 are installed on both sides of the conveyor belt 18. Spraying from both sides of the conveyor belt 18 at the same time can expand the spray coverage area. This allows the dust at various locations of the red mud material to come into more full contact with the mist water droplets during transportation, which can improve dust reduction efficiency and further reduce the dust concentration in the air.
[0046] In some examples, the spray dust removal device for red mud conveying also includes a dust sensor 5, an electric regulating valve 6, and a control module 7. The dust sensor 5 is mounted on the protective cover 1 and located on one side of the nozzle 3. There are multiple dust sensors 5, and each dust sensor 5 is arranged in a one-to-one correspondence with a nozzle 3. The electric regulating valve 6 is connected between the nozzle 3 and the water supply pipe 2, and each electric regulating valve 6 is connected in a one-to-one correspondence with a nozzle 3. The input end of the control module 7 is electrically connected to the dust sensor 5, and the output end of the control module 7 is electrically connected to the electric regulating valve 6.
[0047] For example, such as Figure 1 and Figure 2As shown, the dust sensor 5 can monitor the dust concentration at the corresponding location inside the protective cover 1 in real time and transmit the monitoring data to the control module 7. The control module 7 analyzes and processes the received data. When the dust concentration in a certain area exceeds the set threshold, the control module 7 sends a command to the corresponding electric regulating valve 6. The electric regulating valve 6 adjusts its opening according to the command, controlling the water flow through the nozzle 3, thereby adjusting the spray volume. For example, the spray volume is increased when the dust concentration is high and decreased when the dust concentration is low, achieving the purpose of dynamically adjusting the spray volume according to the actual dust situation. Under the premise of ensuring effective dust reduction, unnecessary water waste can be avoided, operating costs can be reduced, and resource utilization efficiency can be improved.
[0048] In some examples, the spray dust removal device for red mud transportation also includes a booster pump 8 and a main valve 9. One end of the booster pump 8 is connected to the water supply pipe 2, and the other end of the booster pump 8 is connected to the water source. The controlled end of the booster pump 8 is electrically connected to the control module 7. The main valve 9 is connected between the booster pump 8 and the water supply pipe 2, and the controlled end of the main valve 9 is electrically connected to the control module 7.
[0049] For example, such as Figure 1 As shown, the booster pump 8 increases the water pressure in the water supply pipe 2, ensuring that water can be smoothly sprayed out in a mist form through the nozzle 3. The control module 7 controls the start, stop, and operating intensity of the booster pump 8 according to actual needs (such as dust concentration, spray volume requirements, etc.), thereby regulating the water pressure in the water supply pipe 2. The main valve 9 controls the opening and closing of the entire water circuit. The control module 7 can open or close the entire spray system as needed by controlling the opening and closing of the main valve 9. For example, when the equipment is under maintenance or spraying is not required, closing the main valve 9 will cut off the water circuit, improving the controllability and safety of the equipment.
[0050] In some examples, the spray dust removal device for red mud transportation also includes a protective box 10, which is housed inside a protective cover 1. The control module 7 and the pressurizing pump 8 are both housed inside the protective box 10.
[0051] For example, such as Figure 1 As shown, the protective box 10 provides a relatively safe and stable working environment for the control module 7 and the pressurizing pump 8, which can prevent red mud dust, water mist and other substances from corroding and damaging the control module 7 and the pressurizing pump 8, extend the service life of the control module 7 and the pressurizing pump 8 and reduce the maintenance cost of the equipment.
[0052] In some examples, the spray dust removal device for red mud conveying also includes a guide plate 11, which is disposed inside the protective cover 1 and located between the conveyor belt 18 and the feed inlet 4. The upper end of the guide plate 11 is connected to the protective cover 1, and the connection is located on the side of the feed inlet 4 away from the end of the conveyor belt 18. The lower end of the guide plate 11 is inclined toward the end of the conveyor belt 18, and the connection is located between the end of the conveyor belt 18 and the feed inlet 4.
[0053] For example, such as Figure 1 and Figure 3 As shown, the guide plate 11 can change the falling path of the red mud material after it enters the protective cover 1 from the feed inlet 4. When the red mud material falls from the feed inlet 4, it will first come into contact with the guide plate 11. Under the guidance of the guide plate 11, the red mud material slides down the inclined surface of the guide plate 11 onto the conveyor belt 18. This can make the red mud material more evenly distributed on the conveyor belt 18 and reduce the dust generated by direct impact on the conveyor belt 18.
[0054] In some examples, the spray dust removal device for red mud conveying also includes a support member 12, which is located below the guide plate 11. One end of the support member 12 is connected to the protective cover 1, and the other end of the support member 12 is in contact with the lower side of the guide plate 11.
[0055] For example, such as Figure 1 and Figure 3 As shown, the guide plate 11 needs to withstand the impact force of the falling red mud material and its own weight. One end of the support member 12 is fixed on the protective cover 1, and the other end contacts the lower side of the guide plate 11 to form a stable support structure. It can provide support force for the guide plate 11, enhance the stability of the guide plate 11, and prevent the guide plate 11 from deforming or being damaged due to excessive force.
[0056] In some examples, the upper end of the guide plate 11 has an overlap edge 13, the protective cover 1 includes a cylinder 1-1 and a cover plate 1-2, the cylinder 1-1 is located around the conveyor belt 18, the upper end face of the cylinder 1-1 has a receiving groove 14, the overlap edge 13 is inserted into the receiving groove 14, and the water pipe 2 is arranged inside the cylinder 1-1; the cover plate 1-2 is arranged at the upper end of the cylinder 1-1, and the cover plate 1-2 is detachably connected to the cylinder 1-1, and the upper end face of the overlap edge 13 contacts the lower end face of the cover plate 1-2.
[0057] For example, such as Figure 1 and Figure 3As shown, the overlapping edge 13 of the guide plate 11 is inserted into the receiving groove 14 on the cylinder 1-1, which enables the initial positioning and connection of the guide plate 11 and the cylinder 1-1. When the cover plate 1-2 is installed on the cylinder 1-1, it will exert pressure on the overlapping edge 13, further fixing the guide plate 11 and making it more stable. When it is necessary to inspect or replace the guide plate 11, it can be easily operated by removing the cover plate 1-2. This connection method facilitates the installation, disassembly, and maintenance of the guide plate 11, and can improve the maintainability of the equipment.
[0058] In some examples, the inner wall of the cylinder 1-1 has a vertical dovetail groove 15, the upper end of the vertical dovetail groove 15 is connected to the receiving groove 14, the lower end of the vertical dovetail groove 15 is closed, and the end of the support member 12 has a dovetail strip 16, which is inserted into the vertical dovetail groove 15.
[0059] For example, such as Figure 3 and Figure 4 As shown, the dovetail strip 16 on the support member 12 can be inserted along the vertical dovetail groove 15 until it reaches the bottom of the vertical dovetail groove 15. The insertion structure of the vertical dovetail groove 15 and the dovetail strip 16 can provide a reliable installation method for the support member 12, ensuring that the support member 12 will not easily loosen or fall off during operation. This can enhance the firmness and stability of the support member 12, enabling the support member 12 to better provide support for the guide plate 11.
[0060] In some examples, the side of the deflector 11 facing the support 12 has a slot 17 into which the support 12 is inserted.
[0061] For example, such as Figure 3 As shown, the support member 12 is inserted into the slot 17 on the guide plate 11, which can further strengthen the connection between the support member 12 and the guide plate 11, enabling the support member 12 to more effectively transmit force to the guide plate 11 and improve the structural strength and stability of the guide plate 11. At the same time, it also facilitates the installation and disassembly of the support member 12 and the guide plate 11, making it convenient for equipment maintenance and adjustment.
[0062] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
