Description

Technical Field

[0001] This utility model relates to the field of stacker technology, and in particular to a continuous water supply system for a long stacker with a spray nozzle. Background Technology

[0002] Conveyor belts are suitable for material storage yards in large and medium-sized thermal power plants, cement plants, ports, mines, metallurgical plants, and large-scale water conservancy projects. They are efficient and continuous equipment for handling bulk materials. However, in some application scenarios, especially in material handling in mines, they generate a lot of dust, which pollutes the air, affects the environment, and is also harmful to human health.

[0003] Under current technology, common dust suppression methods involve spraying large amounts of water into the unloading port of the stacker crane during material handling. Specific water supply methods include intermittent water supply from water tanks, water cable reels, or water trenches. Intermittent water supply from water tanks is unsuitable for automated continuous operation and requires manual intervention; water cable reel supply is not feasible on some stackers; and water trench supply requires a large area and is prone to water pollution.

[0004] Therefore, how to continuously supply water to long stacker cranes and overcome the defects of intermittent water supply from water tanks, water cable reels, or water ditches has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a continuous water supply system for a long stacking shed stacker, so as to solve the technical problems of many defects in the existing technology of intermittent water supply from water tanks, water supply from water cable reels or water supply from ditches.

[0006] To achieve the above objectives, this utility model provides a continuous water supply system for a long stacker, including a water inlet trough, a water intake pipe, and a water supply drive mechanism. The water inlet trough is connected to a water source and is installed along the track of the stacker. One end of the water intake pipe extends into the water inlet trough, and the other end is connected to the spray system. The water supply drive mechanism is located on the water intake pipe.

[0008] Optionally, the water inlet trough has a side opening, and the water intake pipe extends into the bottom of the water inlet trough from the side opening.

[0009] Optionally, the water intake trough includes a trough body and a bent section. The bent section is a tubular structure with open ends. The bent section is located at the top of the trough body and communicates with the trough body. The extension direction of the bent section is consistent with the extension direction of the trough body. The water intake pipe extends into the trough body through the bent section.

[0010] Optionally, the free end of the bent section is provided with a dustproof mechanism to prevent dust from spilling into the tank body.

[0011] Optionally, the dustproof mechanism includes a first brush and a second brush, which are respectively disposed on the opposite inner walls of the free end of the bent section. The first brush and the second brush are in contact with the opposite side of the inner wall of the bent section, and the water pipe passes through the contact surface of the first brush and the second brush.

[0012] Optionally, the first brush and the second brush are arranged alternately.

[0013] Optionally, the water intake pipe is serpentine.

[0014] Optionally, it also includes a fixing plate, which is fixedly mounted on the stacker. The water pipe is installed on the fixing plate, with one free end extending into the trough body through the bending section and the other free end connected to the spray system.

[0016] The continuous water supply system for spraying on long stacking shed stackers provided by this utility model has the following technical effects:

[0017] This type of continuous water supply system for stacker spraying mainly consists of a water inlet trough, a water intake pipe, and a water supply drive mechanism. The water inlet trough is connected to the water source and installed along the stacker's track. One end of the water intake pipe extends into the water inlet trough, and the other end connects to the spraying system. The water supply drive mechanism is located on the water intake pipe. This invention reduces the floor space occupied by the track-integrated water inlet trough. Compared to the intermittent water supply from the water tank requiring frequent refills, this invention achieves continuous water supply through dynamic water source replenishment. Compared to the water cable reel being limited by the equipment structure, this invention adapts to the moving characteristics of the stacker through track-synchronized water supply. That is, this invention achieves continuous automatic water intake during the stacker's movement, avoiding operation interruptions caused by manual intervention.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] In existing technologies, conveyor belts for stacking materials easily generate a large amount of dust during bulk material transportation, and traditional dust suppression methods have several drawbacks. Intermittent water supply from water tanks requires manual intervention and cannot meet the needs of automated continuous operation; water supply from cable reels is difficult to implement due to the structure of the stacker; and water supply via ditches requires a large area and is prone to water pollution. In high-dust operating environments such as mines, these traditional water supply methods are unable to meet the needs of efficient and continuous dust suppression water supply.

[0025] To address the aforementioned issues, and considering the low automation, poor equipment adaptability, and environmental pollution associated with traditional water supply methods, a structural optimization approach is considered to achieve continuous water supply. While traditional ditch water supply systems can provide a water source, their fixed structure is unsuitable for the operational characteristics of the mobile stacker crane 1. Analysis revealed that integrating the water supply device with the movement trajectory of the stacker crane 1, employing a dynamic water intake method, can overcome the limitations of fixed water supply. Maintaining continuous water supply while ensuring reliable connection between the water supply system and the mobile equipment becomes the key breakthrough direction.

[0026] Therefore, as Figure 1 and Figure 2 As shown, this utility model proposes a continuous spray water supply system for a long stacker shed stacker 1, including a water inlet trough 2, a water intake pipe 3, and a water supply drive mechanism. The water inlet trough 2 is connected to a water source and installed along the track of the stacker 1. One end of the water intake pipe 3 extends into the water inlet trough 2, and the other end is connected to the spray system. The water supply drive mechanism is set on the water intake pipe 3.

[0027] The water inlet trough 2 is a water supply channel made of stainless steel sheet that extends along the track. Specifically, it can be implemented using an open trough structure. Its length direction is parallel to the walking path of the stacker 1, and a dynamic water source is formed by continuously injecting water.

[0028] The water intake pipe 3 is a transmission component that connects the water source and the spraying device. Specifically, it can be implemented using a flexible pipe. During the movement of the stacker 1, the pipe bends and deforms to maintain the connection between the water intake position and the spraying terminal.

[0029] The water intake pipe 3 of this invention is preferably serpentine, meaning that the water intake pipe 3 has a continuously curved shape. Specifically, it can be made of metal flexible tubing or polymer material tubing through molding or cold bending processes to form a wavy or S-shaped structure. This shape increases the flexibility of the pipe by increasing the curvature of the pipe body, enabling it to adapt to the lateral displacement of the stacker 1 when it moves along the track.

[0030] The water supply drive mechanism is a device that provides water flow force. Specifically, it can be implemented by a centrifugal water pump. Mechanical pressurization ensures that the water flow is stably delivered from the water inlet trough 2 to the spray system.

[0031] Centrifugal water pumps are power devices used to deliver high-pressure water to the spray system. Through mechanical pressurization, they continuously deliver water from the water inlet trough 2 to the spray system, thus replacing manual operation or intermittent water supply and ensuring the continuity of dust suppression operations. When the centrifugal water pump is running, it creates a continuous water flow, which, in conjunction with the movement trajectory of the stacker 1, ensures a stable water mist coverage in the material discharge area during material transport, suppressing dust generation.

[0032] Specifically, the water inlet trough 2 is laid along the track of the stacker 1 to form a continuous water supply belt, and the water intake pipe 3 extends into the water body through the opening of the trough to draw water. When the stacker 1 is operating, the water inlet trough 2 continuously replenishes water as it moves along the track, and the water supply drive mechanism drives the water flow through the water intake pipe 3 to deliver it to the spray system. When the stacker 1 changes its operating position, the water intake pipe 3 slides within the water inlet trough 2 to draw water as the equipment moves, achieving synchronous matching between the water supply path and the equipment's movement trajectory.

[0033] Compared with existing technologies, traditional water supply through ditches requires the excavation of fixed trenches, while this invention reduces the footprint by using a track-integrated water inlet channel 2; compared with the need for frequent water replenishment due to intermittent water supply from water tanks, this invention achieves continuous water supply through dynamic water source replenishment; and compared with water cable reels which are limited by equipment structure, this invention adapts to the movement characteristics of the stacker 1 by using track-synchronized water supply.

[0034] Through the above technical solution, this utility model realizes continuous automatic water intake during the movement of the stacker 1, avoiding operation interruption caused by manual intervention, reducing the risk of water pollution through the track-integrated water supply structure, and adapting to the characteristics of mobile operation of the equipment while ensuring dust suppression effect.

[0035] In a preferred embodiment, the water inlet trough 2 has a strip-shaped structure and is installed along the track of the stacker 1.

[0036] In this embodiment, the length direction of the water inlet trough 2 is consistent with the extension direction of the track. This structure can adapt to the linear layout of the stacker 1 track, ensuring that the water inlet trough 2 matches the moving path and facilitating continuous water intake.

[0037] The installation along the track means that the laying path of the water trough 2 is parallel or coincident with the spatial position of the stacker 1's travel track. Specifically, the water trough 2 can be fixed to the side or below the track by pre-embedded brackets or bolts. This arrangement can reduce the additional space occupied and ensure that the water pipe 3 maintains effective contact with the water trough 2 at all times during the movement of the stacker 1.

[0038] As the stacker 1 moves along the track, the water pipe 3 fixed to the stacker 1 moves synchronously with the equipment and continuously draws water from the water inlet trough 2. Because the strip structure of the water inlet trough 2 matches the track layout, the water pipe 3 can achieve stable water intake without significant position adjustments.

[0039] Specifically, in this embodiment, the water inlet trough 2 has an opening on its side, and the water intake pipe 3 extends into the bottom of the water inlet trough 2 from the side opening.

[0040] Specifically, after an opening is made in the side wall of the water inlet trough 2, the water intake pipe 3 extends into the trough through the opening and extends to the bottom area. At this time, when the water supply drive mechanism is activated, water flows from the bottom of the water inlet trough 2 through the water intake pipe 3 to the spray system. Since the end of the water intake pipe 3 is located at the bottom of the trough, even if the water level in the water inlet trough 2 decreases due to changes in the water supply, a stable water intake depth can still be maintained, thereby ensuring continuous water supply.

[0041] Detailed, such as Figure 2 As shown, the water intake tank 2 of this embodiment includes a tank body 21 and a bent section 22. The bent section 22 is a tubular structure with open ends. The bent section 22 is located at the top of the tank body 21 and is connected to the tank body 21. The extension direction of the bent section 22 is consistent with the extension direction of the tank body 21. The water intake pipe 3 extends into the tank body 21 through the bent section 22.

[0042] The main body 21 is the main part of the water inlet trough 2. Specifically, it can be made of metal plates welded into a long strip structure to receive the water flow from the water supply source and extend along the track of the stacker 1.

[0043] The bent section 22 is a transition structure connecting the tank body 21. Its extension direction is consistent with the extension direction of the tank body 21. Specifically, it can be achieved by bending a stainless steel pipe into a U-shape or arc shape. Its two ends are connected to the internal and external environments of the tank body 21, respectively, to provide a channel for the water pipe 3 to enter the tank body 21.

[0044] The inner wall of the bend 22 is smooth to reduce water flow resistance and facilitate the passage of the water pipe 3.

[0045] Specifically, the water intake trough 2 is laid along the track through the trough body 21 to form a continuous water storage space. The bent section 22 is fixed to the top of the trough body 21 and communicates with the interior of the trough body 21 through a through-hole. The water intake pipe 3 enters from one end of the bent section 22, bends and is guided by the bent section 22, and extends to the bottom of the trough body 21. The other end is connected to the spray system. The bending angle of the bent section 22 can be adjusted according to the height of the stacker 1 track, for example, using a bending angle in the range of 30° to 90°, and may include multiple bending angles to adapt to different installation conditions.

[0046] Compared with existing technologies, traditional water supply systems require the excavation of trenches in the ground, which occupies a large area and is prone to pollutant accumulation. However, this invention integrates the water inlet trough 2 onto the track of the stacker 1 through a combination structure of the trough body 21 and the bending section 22, eliminating the need for additional ground construction. The tubular through-hole design of the bending section 22 replaces the traditional side opening structure, preventing external dust from entering the trough body 21 through the opening.

[0047] See also Figure 2 As shown, the present invention further proposes that the free end of the bent section 22 is provided with a dustproof mechanism 4 for preventing dust from spilling into the tank body 21.

[0048] The dustproof mechanism 4 is a barrier device installed at the free end of the bending section 22. Specifically, it can be implemented by a brush group. Its function is to form a physical barrier to prevent external dust from entering the tank body 21, thereby avoiding blockage or pollution of the water supply system due to dust accumulation.

[0049] Specifically, the dustproof mechanism 4 is integrated into the opening at the free end of the bending section 22. When the water intake pipe 3 extends into the tank body 21 through the bending section 22, the dustproof mechanism 4 covers the gap between the water intake pipe 3 and the bending section 22 through contact sealing or dynamic barrier. For example, a multi-layered staggered brush structure can be used. When the water intake pipe 3 passes through the brush, the fibers of the brush are tightly attached to the pipe wall, which allows the water intake pipe 3 to move along the track while continuously preventing external dust from entering the tank body 21 with the airflow. This structure requires no additional power and achieves dynamic sealing through mechanical contact, making it suitable for continuous movement operations of the stacker 1.

[0050] Existing water supply methods using open ditch systems are prone to dust accumulation, requiring frequent cleaning and posing a risk of secondary pollution. This implementation method, through the cooperation of the dustproof mechanism 4 and the bending section 22, forms an active isolation layer at the water inlet, effectively preventing external dust from flowing back in, significantly reducing the risk of water pollution inside the ditch body 21, and reducing the frequency of manual maintenance.

[0051] In detail, the dustproof mechanism 4 mentioned above includes a first brush 41 and a second brush 42. The first brush 41 and the second brush 42 are respectively disposed on the opposite inner walls of the free end of the bending section 22. The first brush 41 and the second brush 42 are in contact with the opposite side of the inner wall of the bending section 22. The water pipe 3 passes through the contact surface of the first brush 41 and the second brush 42.

[0052] The first brush 41 is a flexible sealing component located on the inner wall of one side of the free end of the bending section 22. It can be made of polypropylene or nylon bristles with a bristle density of 15-20 bristles per square centimeter. This brush contacts the outer wall of the water intake pipe 3 through elastic deformation, forming a dynamic sealing barrier to prevent external dust from entering the tank body 21. The second brush 42 is a sealing component symmetrically arranged on the inner wall of the other side of the bending section 22, and can use the same material and structural parameters as the first brush 41. The two brushes form an interlaced sealing surface. As the water intake pipe 3 moves with the stacker 1, the brushes continuously scrape the pipe wall surface, removing dust particles adhering to the water intake pipe 3.

[0053] Specifically, two sets of brushes are installed at opposite positions on the inner wall of the free end of the bending section 22. The bristle tips of the two sets of brushes contact each other in their natural state, forming a closed interface. When the water intake pipe 3 passes through the contact surface between the two sets of brushes, the brushes are compressed, causing radial deformation, and their bristles tightly wrap around the outer wall of the water intake pipe 3. When the stacker 1 moves along the track, causing lateral displacement of the water intake pipe 3, the elastic deformation characteristics of the brushes ensure that it always maintains contact and seals with the pipe wall. The physical barrier formed by the brushes effectively prevents dust from entering the tank body 21 in the reverse direction with the airflow.

[0054] The elastic contact characteristics of the brush structure consisting of the first brush 41 and the second brush 42 described in this embodiment not only ensure the sealing effect, but also compensate for the relative movement deviation between the water pipe 3 and the bending section 22, which is especially suitable for the working condition of the stacker 1 moving frequently on a long track.

[0055] In this embodiment, the first brush 41 and the second brush 42 are preferably arranged in an alternating manner. An alternating arrangement means that the fibers of the two sets of brushes form an asymmetrical arrangement structure in terms of spatial distribution. Specifically, this can be achieved by staggered installation or cross-layering, and the dustproof effect is enhanced by the complementary coverage of the fiber gaps.

[0056] In a more preferred embodiment, a fixing plate 5 is also included. The fixing plate 5 is fixedly mounted on the stacker 1, and the water pipe 3 is installed on the fixing plate 5. One free end extends into the tank body 21 through the bending section 22, and the other free end is connected to the spray system.

[0057] In this embodiment, the fixing plate 5 is a plate-shaped structure used to support and fix the water-drawing pipe 3. Specifically, it can be made of steel plate or aluminum alloy plate and fixed to a suitable position on the stacker 1 by bolts or welding. Its function is to provide a stable installation base for the water-drawing pipe 3 and prevent the pipe from shaking or falling off due to the movement of the stacker 1. The water-drawing pipe 3 is arranged along the surface of the fixing plate 5 and fixed to the plate surface by pipe clamps or clamps. One end of it passes through the dustproof mechanism 4 of the bending section 22 and extends to the bottom of the water inlet trough 2. The other end is directly connected to the water inlet of the spray system through a hose or rigid pipe. Thus, when the stacker 1 runs along the track, the water-drawing pipe 3 moves synchronously with the fixing plate 5, and provides a stable water source for the spray system by continuously drawing water from the water inlet trough 2.
