Description

Technical Field

[0001] This utility model relates to the technical field of flow stabilization devices for thickeners; more specifically, it relates to flow stabilization devices for thickeners in coal preparation plants. Background Technology

[0002] A coal preparation plant thickener is an important piece of equipment used for solid-liquid separation. It is mainly used to treat coal slurry water and realize closed-loop circulation of washing water. The flow stabilizing device is an important component of the thickener, and its function is to ensure the stable flow of slurry in the thickener and improve the separation efficiency.

[0003] Currently, while existing thickener flow stabilization devices perform well in use, their internal buffer grids are prone to corrosion or wear after prolonged use, leading to a decline in buffering performance. Due to structural design limitations, it is often difficult for operators to easily disassemble and replace the buffer grids, which not only increases maintenance difficulty but also reduces the practicality of the equipment to some extent. Furthermore, the buffer flow stabilization area of ​​the equipment is usually in a closed state, making it easy for coal slurry and water residue to accumulate inside after shutdown, which makes cleaning very inconvenient. If the residue is not removed in time, it may affect the stability of subsequent operation and reduce the practicality of the equipment to some extent. Therefore, there is an urgent need for a coal preparation plant thickener flow stabilization device to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a flow stabilizing device for a coal preparation plant thickener to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a flow stabilizing device for a coal preparation plant thickener, comprising: The base plate has a disassembly structure at its inner top and a flow stabilizing barrel on its bottom surface. The disassembly structure also has a positioning structure at its inner bottom. The disassembly structure includes an energy dissipation plate, which is fixedly connected to the inner top of the disassembly structure. The positioning structure includes an installation groove, and there are two sets of installation grooves, which are respectively opened on both sides of the bottom surface of the base plate.

[0006] Preferably, the disassembly structure further includes insertion slots, and multiple sets of insertion slots are provided. All sets of insertion slots are opened on the outside of the energy dissipation plate, and a counterweight slot is opened at the top of the insertion slot. A counterweight block is inserted into the counterweight slot, and a positioning plate is fixedly connected to the bottom surface of the counterweight block. A pull plate is fixedly connected to one side of the outer surface of the counterweight block. An energy dissipation grid is inserted into the multiple sets of insertion slots, and a positioning slot is opened on the top surface of the energy dissipation grid. This design allows for the disassembly of the energy dissipation grid.

[0007] Preferably, a limiting groove is provided on one side of each of the multiple sets of counterweight grooves, and the internal dimensions of the limiting groove are adapted to the external dimensions of the pull plate. This design allows the pull plate to move while conforming to the inner wall of the limiting groove.

[0008] Preferably, the internal dimensions of the counterweight groove are adapted to the external dimensions of the counterweight block, and the external dimensions of the positioning plate are adapted to the internal dimensions of the positioning groove. This design allows the positioning plate to maintain a stable vertical movement direction.

[0009] Preferably, the positioning structure further includes a sliding groove, and there are two sets of sliding grooves. The two sets of sliding grooves are respectively opened on one side of one end of the two sets of mounting grooves. A groove is opened at the bottom end of one side of the sliding groove. A spring is fixedly connected inside the groove. A limiting plate is fixedly connected to the top surface of the spring. A locking block is fixedly connected to the top surface of the limiting plate. An insertion plate is inserted inside the sliding groove. A locking groove is opened on one side of the bottom surface of the insertion plate. A water distribution plate is fixedly connected to the bottom surface of the insertion plate. This design can perform positioning operations on the position of the insertion plate after it has been moved.

[0010] Preferably, the internal dimensions of the groove are adapted to the external dimensions of the limiting plate, which makes the movement of the locking block more stable.

[0011] Preferably, the two sides of the outer surface of the card block are designed to be inclined, and the external dimensions of the card block are adapted to the internal dimensions of the card slot. This design allows the card block to be accurately inserted into the inside of the card slot.

[0012] Preferably, the outer surface of the insertion plate is L-shaped, which allows the insertion plate to be smoothly inserted into the mounting slot and move stably inside the slot.

[0013] The technical effects and advantages of this utility model are as follows: By pulling the pull plate upwards, when the pulling force is greater than the weight of the counterweight, the counterweight can be slowly moved upwards inside the counterweight groove, and the positioning plate will also be moved upwards until the positioning plate is removed from the inside of the positioning groove. At this time, the positioning effect on the energy dissipation grid can be canceled. The energy dissipation grid can then be removed from the insertion groove. The above operation can be repeated to replace other energy dissipation grids that need to be replaced. This design makes it convenient for staff to replace the energy dissipation grid when it is corroded or worn, so as to maintain the stable use effect of the energy dissipation grid. At the same time, this operation is relatively simple and convenient, making maintenance work simpler and more convenient, thereby improving the practicality of the equipment to a certain extent. By rotating the water distribution plate, the insertion plate moves accordingly. When the rotational force exceeds the spring force, the inner wall surface of the slot abuts against the inclined surface of the locking block, pressing the locking block back into the groove until it disengages from the slot. Then, the insertion plate moves along the inside of the sliding groove until it reaches the position of the installation slot. At this point, the water distribution plate can be pulled down directly, and the insertion plate removed from the installation slot, thus completing the disassembly of the water distribution plate. This design allows for the disassembly of the water distribution plate. After the water distribution plate is disassembled, a water gun can be sprayed from the bottom of the flow stabilizing tank into the interior of the base plate to clean the coal slurry residue on the surface of the flow stabilizing tank, ensuring the stable operation of subsequent equipment and improving the practicality of the equipment to a certain extent. Moreover, its overall structure is simple and reasonable, highly practical, and easy to promote and apply. Attached Figure Description

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The concentrator flow stabilizing device involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1, as Figures 1-4 As shown, this embodiment proposes a flow stabilization device for a coal preparation plant thickener, including: The bottom plate 1 has a disassembly structure 2 at its top interior and a flow stabilizing tank 3 on its bottom surface. The bottom interior of the disassembly structure 2 has a positioning structure 4. With the help of the flow stabilizing tank 3, when coal slurry water enters the interior of the bottom plate 1, it can flow slowly downward along the outer surface of the flow stabilizing tank 3 to achieve the effect of flow stabilization. The disassembly structure 2 includes an energy dissipation plate 21, which is fixedly connected to the top of the disassembly structure 2. The disassembly structure 2 also includes an insertion slot 22, which is provided in multiple sets. All sets of insertion slots 22 are opened on the outside of the energy dissipation plate 21. The top of the insertion slot 22 is provided with a counterweight slot 23. A counterweight block 24 is inserted into the counterweight slot 23. A positioning plate 25 is fixedly connected to the bottom surface of the counterweight block 24. A pull plate 26 is fixedly connected to one side of the outer surface of the counterweight block 24. Energy dissipation grids 27 are inserted into the multiple sets of insertion slots 22. A positioning slot 28 is opened on the top surface of the energy dissipation grids 27. This design, under the action of the energy dissipation grids 27 and the energy dissipation plate 21, can provide a preliminary kinetic energy effect to the coal slurry water inside the energy dissipation plate 21. Each of the multiple counterweight grooves 23 has a limiting groove on one side, and the internal dimensions of the limiting groove are adapted to the external dimensions of the pull plate 26. This design can limit the pull plate 26, so that the pull plate 26 always moves up and down inside the limiting groove, and the counterweight 24 also moves a consistent distance, thereby preventing the counterweight 24 from leaving the interior of the counterweight groove 23. The internal dimensions of the counterweight groove 23 are adapted to the external dimensions of the counterweight block 24, and the external dimensions of the positioning plate 25 are adapted to the internal dimensions of the positioning groove 28. This design allows the positioning plate 25 to be accurately inserted into the interior of the positioning groove 28.

[0023] Example 2, as Figure 5 and Figure 6 As shown, based on the same concept as the above embodiments, this embodiment also proposes: The positioning structure 4 includes two sets of mounting grooves 41, which are respectively located on both sides of the bottom surface of the base plate 1. The positioning structure 4 also includes two sets of sliding grooves 42, which are respectively located on one side of one end of the two sets of mounting grooves 41. A groove 43 is formed at the bottom end of one side of the sliding groove 42, and a spring 44 is fixedly connected inside the groove 43. A limit plate 45 is fixedly connected to the top surface of the spring 44. A locking block 46 is fixedly connected to the top surface of the limiting plate 45. An inserting plate 47 is inserted into the inside of the sliding groove 42. A slot 48 is opened on one side of the bottom surface of the inserting plate 47. A water distribution plate 49 is fixedly connected to the bottom surface of the inserting plate 47. Under the elastic action of the spring 44, the limiting plate 45 can be popped outward. When the limiting plate 45 is inserted into the slot 48, the position of the inserting plate 47 after movement can be positioned to maintain the stable position of the water distribution plate 49. The internal dimensions of the groove 43 are adapted to the external dimensions of the limiting plate 45. This design can limit the locking block 46 and prevent the locking block 46 from dislodging from the inside of the groove 43. The outer surface of the card block 46 is inclined on both sides, and the external dimensions of the card block 46 are adapted to the internal dimensions of the card slot 48. When the insertion plate 47 moves to the bottom position inside the slide groove 42, the outer surface of the insertion plate 47 can move against the inclined surface on one side of the card block 46. When the insertion plate 47 moves in the opposite direction, the inner wall surface of the card slot 48 can move against the inclined surface on the other side of the card block 46, making the movement of the insertion plate 47 smoother. The outer surface of the insertion plate 47 is designed in an L-shape. This L-shape design allows the insertion plate 47 to be inserted only from the position of the mounting slot 41 and to move stably inside the sliding groove 42. The energy dissipation grid 27, the flow stabilizing tank 3, and the water distribution pan 49 in this application are products that can be purchased directly on the market. Their principles, connection methods, and control methods are all existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0024] Working Principle: When the equipment is in use, after it is installed in a suitable position on the thickener, high-speed coal slurry enters the energy dissipation plate 21 tangentially or perpendicularly from the feed pipe. The energy dissipation plate 21 acts as a shield. When a suitable amount of coal slurry enters the energy dissipation plate 21, the high-speed water flow impacts it, causing friction and collisions between the water streams. This is analogous to punching a soft sandbag, effectively consuming and dispersing the enormous impact energy, thus achieving initial kinetic energy dissipation. Subsequently, the coal slurry falls from the energy dissipation grid 27 into the bottom plate 1. Here, the energy dissipation grid 27 also dissipates some of the impact energy of the coal slurry. The dissipated coal slurry then enters the outer surface of the flow stabilizing tank 3, finally providing a calm transition space. The water flow is further stabilized, transitioning from a turbulent state to a near-laminar state, and then slowly flows out through the distribution plate 49 into the settling area of ​​the thickener to complete the flow stabilization operation. During long-term use of the equipment, the energy dissipation grid 27 may be corroded or worn, affecting the subsequent energy dissipation effect. At this time, simply pull the pull plate 26 upward. When the pulling force is greater than the weight of the counterweight block 24, the counterweight block 24 can be slowly moved upward inside the counterweight groove 23, and the positioning plate 25 will be moved upward along with it until the positioning plate 25 is removed from the inside of the positioning groove 28. Then the positioning effect of the energy dissipation grid 27 can be canceled, and the energy dissipation grid 27 can be removed from the inside of the insertion groove 22. Repeat the above operation to replace other energy dissipation grids 27 that need to be replaced, so as to facilitate the replacement operation by the staff and maintain the stable use effect of the energy dissipation grid 27. After the equipment is used, rotate the water distribution plate 49 to move the insertion plate 47. When the rotational force is greater than the elastic force of the spring 44, the inner wall surface of the slot 48 will contact the inclined surface of the block 46, pressing the block 46 back into the groove 43 until the block 46 disengages from the slot 48. Then, the insertion plate 47 can move along the slide groove 42 until it reaches the position of the mounting groove 41. At this point, the water distribution plate 49 can be pulled down directly, and the insertion plate 47 can be removed from the mounting groove 41 to complete the disassembly of the water distribution plate 49. At this point, the bottom of the flow stabilizer 3 will no longer be obstructed, and the water gun can be inserted into the bottom plate 1 to rinse all corners of the flow stabilizer 3 to keep the surface of the flow stabilizer 3 clean and avoid residual coal slurry water as much as possible, thus maintaining the stable performance of the flow stabilizer 3. Simultaneously, this operation can also perform regular cleaning of the water distribution pan 49 to maintain a stable drainage effect. After cleaning the outer surfaces of the water distribution pan 49 and the flow stabilizing tank 3, insert the two sets of insertion plates 47 into the two sets of mounting slots 41, and then rotate the water distribution pan 49 so that the insertion plates 47 move towards the bottom inside the sliding groove 42. When the pushing force is greater than the elastic force of the spring 44, the outer surface of the insertion plate 47 can abut against the inclined surface of the locking block 46 and press the locking block 46 back into the groove 43 again until the locking block 46 moves back to the appropriate position. Then, the insertion plate 47 can be moved to the bottom position of the sliding groove 42. At this time, the locking block 46 and the locking groove 48 are in corresponding positions, and under the elastic force of the spring 44, the locking block 46 can be ejected outward and locked into the inside of the locking groove 48 to perform the positioning operation of the insertion plate 47. The above is the complete working principle of this utility model.
