Description

Technical Field

[0001] This utility model relates to the field of coal mining technology, specifically to a cooling water spray device for belt conveyors. Background Technology

[0002] Belt conveyors, also known as belt conveyors or belt conveyors, are a common type of logistics transportation equipment, widely used in assembly lines. In the mining industry, belt conveyors are continuous transportation equipment used in mine roadways. These machines operate on the principle of friction transmission and are mainly suitable for conveying easily accessible powdery, granular, and small lump materials, as well as bagged materials such as coal, gravel, and cement, with a bulk density of less than 1.67 tons / cubic meter.

[0003] During the transportation of coal blocks using belt conveyors, the coal blocks undergo wear and breakage due to compression, generating dust. Coal may scatter on the conveyor belt, producing a large amount of dust. To address this dust problem, dust suppression measures need to be implemented for belt conveyors, such as negative pressure suction, spray dust suppression, and covering dust suppression.

[0004] Currently used dust suppression spraying equipment typically employs a comprehensive coverage spraying method, encompassing the entire belt conveyor system within the spray range.

[0005] While this comprehensive dust suppression solution can achieve a certain dust control effect, it cannot be precisely adjusted according to the actual dust concentration in different sections of the belt conveyor. Since the dust level in different locations often varies significantly, some areas may have a high dust concentration and require focused dust suppression, while other areas have less dust and do not require excessive spraying. This makes it difficult to achieve such targeted local dust suppression treatment, resulting in a waste of water and energy resources.

[0006] Therefore, we proposed a cooling water spray device for belt conveyors to solve the above problems. Utility Model Content

[0007] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a cooling water spray device for belt conveyors, which solves the problems mentioned in the background section.

[0008] (II) Technical Solution To achieve the above objectives, this utility model specifically adopts the following technical solution: A belt conveyor cooling water spray device includes a conveying device and a mobile dust suppression spray structure. The conveying device is located inside the mobile dust suppression spray structure and is within the spray range of the mobile dust suppression spray structure. A controller is provided on the outside of the mobile dust suppression spray structure. The mobile dust suppression spray structure includes a support frame, and a first drive structure and a second drive structure are provided at the top of the support frame. The first drive structure and the second drive structure contain the same structure, and a spraying device is provided between the movable ends of the first drive structure and the second drive structure.

[0009] Furthermore, the conveying device includes a conveying frame, with a conveying wheel and a lifting shaft arranged on the inner side of the conveying frame. A conveyor belt is connected between the conveying wheel and the lifting shaft, and the conveying wheel is driven by an external motor.

[0010] Furthermore, the first drive structure includes a mounting plate, and a drive wheel and a transmission wheel are rotatably connected to the top of the mounting plate. The drive wheel and the transmission wheel are connected by a transmission chain, and the drive wheel is driven by an external motor.

[0011] Furthermore, a sliding rail is fixedly connected to the top of the mounting plate, a movable seat is slidably connected to the surface of the sliding rail, and a connecting sleeve block is fixedly installed on the top of the movable seat.

[0012] Furthermore, the inner wall of the connecting sleeve is fixedly sleeved with the upper half of the transmission chain, and the inner wall of the movable seat is movably sleeved with the lower half of the transmission chain.

[0013] Furthermore, a follower wheel is provided on the outer side of the movable seat, and a guide rail is fixedly installed on the outer wall of the mounting plate, with the bottom end of the follower wheel overlapping the inner wall of the guide rail.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0020] like Figure 1-5As shown, an embodiment of the present invention provides a belt conveyor cooling water spray device, which includes a conveying device 1 and a mobile dust suppression spray structure 2. The conveying device 1 is located inside the mobile dust suppression spray structure 2 and is within the spraying range of the mobile dust suppression spray structure 2. A controller 3 is provided on the outside of the mobile dust suppression spray structure 2.

[0021] The mobile dust suppression spray structure 2 includes a support frame 201. The top of the support frame 201 is provided with a first drive structure 202 and a second drive structure 203. The first drive structure 202 and the second drive structure 203 have the same structure. A spraying device 204 is provided between the movable ends of the first drive structure 202 and the second drive structure 203.

[0022] In order to avoid the spray device 204 from being displaced unevenly or jammed due to the asynchronous movement of the first drive structure 202 and the second drive structure 203, the first drive structure 202 and the second drive structure 203 are linked and controlled by the controller 3. The controller 3 can precisely regulate the start, stop and running speed of the two drive structures to ensure that they always maintain a synchronous movement state.

[0023] During actual operation, the controller 3, according to preset program instructions, simultaneously sends the same control signal to the external motor 208 of the first drive structure 202 and the external motor 208 of the second drive structure 203, causing the two drive wheels 206 to rotate at the same speed and direction. This, in turn, drives the moving seat 210 and the spraying device 204 on it to move smoothly and synchronously via the transmission chain belt 209. This synchronous control method ensures that the spraying device 204 can move accurately above the belt conveyor along a predetermined trajectory, thereby achieving precise dust suppression in different sections.

[0024] like Figure 2 As shown, in some embodiments, the conveying device 1 includes a conveying frame 101, with a conveying wheel 102 and a lifting shaft 103 disposed on the inner side of the conveying frame 101. A conveyor belt 104 is connected between the conveying wheel 102 and the lifting shaft 103. The conveying wheel 102 is driven by an external motor.

[0025] Specifically, after the external motor starts, it drives the conveyor wheel 102 to rotate. The conveyor wheel 102 is connected to the lifting shaft 103 through a transmission, which enables the conveyor belt 104 to run continuously and stably, thereby realizing the conveying operation of materials such as coal.

[0026] like Figure 3As shown, in some embodiments, the first drive structure 202 includes a mounting plate 205, and a drive wheel 206 and a transmission wheel 207 are rotatably connected to the top of the mounting plate 205. The drive wheel 206 and the transmission wheel 207 are connected by a transmission chain belt 209, and the drive wheel 206 is driven by an external motor 208.

[0027] Specifically, when the external motor 208 starts, it drives the drive wheel 206 to rotate. The drive wheel 206 transmits power to the transmission wheel 207 through the transmission chain 209, so that the entire transmission system starts to work. This transmission method is stable and reliable, which can ensure the normal operation of the drive structure and thus provide power support for the movement of the spray device 204.

[0028] Meanwhile, the mounting plate 205 provides a stable mounting base for the drive wheel 206 and the transmission wheel 207, ensuring their stability and accuracy during operation.

[0029] like Figure 4 As shown, in some embodiments, a sliding rail 212 is fixedly connected to the top of the mounting plate 205, a movable seat 210 is slidably connected to the surface of the sliding rail 212, and a connecting sleeve block 211 is fixedly installed on the top of the movable seat 210.

[0030] Specifically, the design of the sliding track 212 provides a precise movement path for the movable seat 210, ensuring that the movable seat 210 can slide along the predetermined trajectory.

[0031] The connecting sleeve 211 serves as a connector between the movable seat 210 and the transmission chain 209. It not only achieves a stable connection between the two but also ensures that the transmission chain 209 can drive the movable seat 210 to move synchronously during rotation.

[0032] In addition, the surface of the sliding track 212 is specially treated to have a low coefficient of friction, which helps to reduce the resistance of the moving seat 210 during the sliding process and improve the moving efficiency.

[0033] like Figure 4 As shown, in some embodiments, the inner wall of the connecting sleeve 211 is fixedly sleeved with the upper half of the transmission chain 209, and the inner wall of the movable seat 210 is movably sleeved with the lower half of the transmission chain 209.

[0034] Specifically, this allows the drive chain belt 209 to move synchronously with the movable seat 210 via the connecting sleeve 211 when it rotates. The fixed connection between the connecting sleeve 211 and the upper part of the drive chain belt 209 ensures a stable connection between the two and prevents them from loosening or falling off due to the rotation of the drive chain belt 209.

[0035] The movable connection between the inner wall of the movable seat 210 and the lower half of the transmission chain 209 allows the transmission chain 209 to maintain a certain relative movement with the movable seat 210 during rotation.

[0036] like Figure 4 As shown, in some embodiments, a follower wheel 213 is provided on the outer side of the movable seat 210, and a guide rail 214 is fixedly installed on the outer wall of the mounting plate 205. The bottom end of the follower wheel 213 overlaps with the inner wall of the guide rail 214.

[0037] Specifically, the design of the follower wheel 213 further enhances the stability of the movable seat 210 during the sliding process. When the movable seat 210 moves along the sliding track 212, the follower wheel 213 rolls on the inner wall of the guide track 214. This rolling contact not only reduces the frictional resistance during the movement, but also ensures that the movable seat 210 can move strictly according to the predetermined trajectory without any deviation or shaking.

[0038] like Figure 5 As shown, in some embodiments, the spraying device 204 includes a mounting frame 215, a placement plate 216 is fixedly mounted on the back side of the mounting frame 215, a storage tank 217 is provided at the top of the placement plate 216, a water pump 218 is provided on the back side of the storage tank 217, and a connecting pump is provided at the bottom of the storage tank 217.

[0039] Specifically, pump 218 is responsible for delivering cooling water from the coal mining system into storage tank 217, and then, via a connecting pump, transporting the storage tank 217 to the distribution pipe 219. As a key piece of equipment for cooling water circulation in the coal mining system, pump 218's main function is to extract and transport the cooling water generated during coal mining operations. This pump draws high-temperature cooling water from the coal face through a dedicated pipeline system and safely transports it to the designated storage tank 217 for temporary storage.

[0040] Storage tank 217 serves as a transfer container for cooling water, and a pump is connected to continue to transport the stored cooling water to the downstream branch pipe 219.

[0041] This complete conveying system ensures the recycling of cooling water in the coal mining system, which not only meets the equipment cooling needs but also achieves effective water resource recovery.

[0042] like Figure 5 As shown, in some embodiments, a diversion pipe 219 is fixedly installed at the bottom of the mounting frame 215, and the storage tank 217 and the diversion pipe 219 are connected by a connecting pump. A spray nozzle 220 is provided at the water outlet end of the diversion pipe 219.

[0043] Specifically, after the connection pump is started, it pressurizes the water in the storage tank 217 and delivers it to the distribution pipe 219. The distribution pipe 219 distributes the water to each spray nozzle 220 according to the design. The spray nozzle 220 adopts a special atomization design, which can disperse the water into fine and uniform water mist particles. These water mist particles have a large specific surface area, which can more effectively capture and adsorb dust particles in the air, thereby achieving a good dust reduction effect.

[0044] During use, the controller 3 will adjust the position and spray volume of the spray device 204 in real time based on the dust concentration data reported by the staff; Under normal working conditions, since the material conveying equipment 1 is constantly running, the matching spraying device 204 can remain in a fixed position without the need to additionally start the first drive structure 202 and the second drive structure 203. Under these operating conditions, the entire system only needs to start the water pump 218 to extract cooling water, and at the same time cooperate with the connecting pump to perform dust suppression on the conveying equipment 1. When the dust concentration in a certain area increases, the controller 3 will quickly issue an instruction to control the rotation speed and direction of the first drive structure 202 and the second drive structure 203, so that the moving seat 210 drives the spraying device 204 to move quickly to the area and increase the spray volume for targeted dust suppression. An external motor 208 can drive the drive wheel 206 to rotate. The drive wheel 206 transmits power to the transmission wheel 207 through the transmission chain belt 209, which makes the entire transmission system start working. This causes the connecting sleeve block 211 to drive the moving seat 210 to slide along the sliding track 212, so that the moving seat 210 is displaced. The two moving seats 210 can jointly drive the mounting crossbeam 215 to move. Once the movable seat 210 drives the mounting frame 215 to the target position, the controller 3 will further control the working status of the water pump 218 and the connecting pump, adjust the amount of water delivered from the storage tank 217 to the distribution pipe 219 according to the actual dust concentration, and then distribute it evenly to each spray nozzle 220 through the distribution pipe 219 to achieve precise and efficient spray dust suppression operation.

[0045] In summary, the mobile dust suppression spray structure 2, with its support frame 201, allows for the stable installation of two drive structures. These two drive structures can synchronously displace the spray device 204, enabling the spray device 204 to perform targeted localized dust suppression based on the actual dust concentration in different sections of the conveyor belt. This allows for increased spray volume for focused dust suppression or reduced or stopped spraying in specific areas. This differentiated dust suppression strategy not only ensures overall dust suppression effectiveness but also avoids excessive water consumption caused by traditional generalized spraying by adjusting the spray volume, thus achieving efficient water utilization and conservation.

[0046] It should be noted that the specific models and specifications of the external motor, external motor 208, water pump 218, and connecting pump in the cooling water spray device of the belt conveyor need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0047] Furthermore, the power supply and operating principle of the external motor, external motor 208, water pump 218, and connecting pump in the cooling water spray device of the belt conveyor are clear to those skilled in the art and will not be described in detail here.

[0048] Furthermore, the working principles and wiring methods of the external motor, external motor 208, water pump 218, and connecting pump in the cooling water spray device of the belt conveyor are commonplace and belong to conventional methods or common knowledge. They will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0049] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
