Description

Technical Field

[0001] This utility model relates to the technical field of tailings washing and beneficiation equipment, specifically a tailings sludge treatment equipment efficiency improvement device. Background Technology

[0002] Inclined plate thickeners are widely used in various fields that require sedimentation and concentration due to their excellent settling performance.

[0003] The inclined plate thickener mainly consists of two chambers, an upper chamber containing a thin inclined plate with an angle of approximately 55°, and a lower chamber consisting of a conical slurry hopper, also known as a square cone hopper. The slurry enters the thickener from one side of the upper chamber and then flows through a side opening into the gaps in the inclined plate. The slurry is clarified within the inclined plate; the clarified liquid does not mix with the incoming slurry but is discharged through the upper overflow trough.

[0004] Within the inclined plates, due to the small spacing between them, the fluid easily forms laminar flow during movement. Solid particles in the slurry settle onto the inclined plates under gravity, requiring only a short settling distance to reach the plates, and then slide down the inclined plates into the lower conical hopper. The main function of the conical hopper is to collect and concentrate these sediments sliding down the inclined plates. Its conical design allows the sediments to accumulate smoothly at the bottom and be discharged through the discharge pipe or gate valve. However, in actual operation, because coal slime flocs are large and highly viscous, when they accumulate in the conical hopper, they can stick together and adhere to the inner wall of the hopper. This results in a longer discharge time for the coal slime flocs to be discharged from the gate valve at the bottom of the conical hopper. Even more seriously, the coal slime flocs may directly block the gate valve, making discharge impossible and requiring cleaning from the top using a scraper, causing an interruption in the operation.

[0005] This shows that the current problem of coal slime clogging in inclined plate thickeners is quite serious and urgently needs to be solved. Utility Model Content

[0006] To avoid and overcome the technical problems existing in the prior art, this utility model provides an efficiency improvement device for tailings sludge treatment equipment. This utility model effectively reduces the adhesion strength of coal sludge flocs through vibration, thereby eliminating the clogging problem of the inclined plate thickener.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An efficiency improvement device for tailings sludge treatment equipment includes an inclined plate thickener. An installation base is fixedly installed on the outer wall of the square cone bucket of the inclined plate thickener. The installation base has an installation hole that matches the through hole on the vibrator base. A locking bolt passes through the installation hole and the matching through hole and forms a threaded engagement with the locking nut to fix the vibrator on the installation base.

[0009] As a further improvement of this utility model, the mounting base is made of metal and is fixedly installed on the outer wall of the square cone bucket by welding.

[0010] As a further embodiment of this utility model: the mounting base includes a base plate, which is fixedly mounted on the outer wall of the square cone bucket; a support plate is fixedly mounted on the bottom edge of the base plate, and a positioning groove with an upward-facing opening and a horizontally arranged groove length is opened on the upper surface of the support plate, the groove length direction being parallel to the base plate surface; the lower edge of the vibrator base is embedded in the positioning groove, and the upper edge of the vibrator base rotates towards the base plate with the positioning groove as the rotation fulcrum; a pry bar with a hook is hinged at the upper edge of the base plate, and the driving end of the pry bar is located on the rotation path of the upper edge of the vibrator base, so that the rotating vibrator base drives the pry bar to flip and its hook portion hooks onto the upper edge of the vibrator base.

[0011] As a further improvement of this utility model: the pry bar is an L-shaped bar, with the middle of its long section hinged to the base plate, and its short section forming the hook portion.

[0012] As a further improvement of this utility model: the hinge axis of the pry bar is arranged horizontally and is parallel to the surface of the base plate.

[0013] As a further improvement of this utility model, a permanent magnet is installed on the hook part of the pry bar, which can magnetically attract the vibrator base.

[0014] As a further improvement of this utility model, the support plate is arranged vertically on the substrate.

[0015] As a further improvement of this utility model, the groove opening direction of the positioning groove is parallel to the surface of the substrate.

[0016] As a further embodiment of this utility model: the substrate and the outer wall of the square cone bucket are fixedly connected to each other by connecting blocks, the four corners of the substrate extend out connecting blocks and form a cavity between them and the outer wall of the square cone bucket, and mounting holes are provided on the four corners.

[0017] As a further improvement of this utility model, the thickness of the clamping cavity is greater than the length of the locking bolt extending out of the mounting hole.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This application introduces a vibrator and cleverly fixes it to the outer wall of the square cone bucket of the inclined plate thickener. The vibration effectively reduces the adhesion strength of coal slime flocs, directly solving the common clogging problem of the inclined plate thickener, improving washing efficiency, reducing equipment downtime for maintenance, and thus improving overall production efficiency and equipment stability.

[0020] 2. The mounting base is made of metal and fixed to the outer wall of the square cone bucket by welding, which significantly enhances the stability and durability of the structure. The choice of metal material ensures that the base can withstand the vibration of the vibrator during operation without being easily damaged, while welding ensures a tight connection between the base and the square cone bucket, avoiding a decrease in vibration transmission efficiency or equipment failure due to loosening.

[0021] 3. By adding a base plate, support plate, and positioning groove, a precise and stable installation position is provided for the vibrator. At the same time, the introduction of a pry bar makes the installation and disassembly of the vibrator much more convenient; the vibrator can be quickly fixed or released simply by prying, greatly improving work efficiency and reducing operational difficulty.

[0022] 4. The pry bar adopts an L-shaped design, which simplifies the structure and facilitates operation. The middle of the long bar section is hinged to the base plate, and the short bar section forms a hook. This layout makes the pry bar more stable when under force, and the hook can more effectively hook the vibrator base, ensuring that the vibrator will not fall off during vibration.

[0023] 5. The hinge axis of the pry bar is horizontal and parallel to the base plate surface. This design ensures that the pry bar can maintain a stable movement trajectory during prying, avoiding prying failure or equipment damage caused by improper hinge point position, and further improving the reliability and safety of the device.

[0024] 6. Installing a permanent magnet at the hook of the pry bar allows for magnetic connection with the vibrator base. This not only enhances the stability of the vibrator during installation but also makes it easier to disassemble without additional tools or force, improving work efficiency and ease of operation.

[0025] 7. The support plate is vertically arranged on the base plate, providing a stable support surface for the vibrator and ensuring the accurate opening of the positioning groove, so that the vibrator base can be accurately embedded, improving the installation accuracy and stability.

[0026] 8. The groove opening is parallel to the substrate surface. This design ensures that the vibrator base remains parallel to the substrate when it is embedded in the positioning groove, avoiding installation difficulties or uneven vibration transmission caused by angular deviation, and maximizing the vibration effect.

[0027] 9. The base plate and the outer wall of the square cone bucket are fixed together by connecting blocks, and clamping cavities are formed at the four corners. This design not only enhances the connection strength between the base plate and the square cone bucket, but also provides additional space for the installation of locking bolts, making the bolts more secure and improving the structural strength and stability of the entire device.

[0028] 10. The thickness of the clamping cavity is greater than the length of the locking bolt extending out of the mounting hole. This design ensures that the locking bolt is not restricted by insufficient space in the clamping cavity during the tightening process, and can give full play to its tightening function. This ensures a tight connection between the vibrator and the mounting base, and improves the overall stability and reliability of the equipment. Attached Figure Description

[0035] 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.

[0036] Please see Figures 1-5 In this embodiment of the utility model, a tailings slurry treatment equipment efficiency improvement device includes an inclined plate thickener 1 and a vibrator 5, and the inclined plate thickener 1 and the vibrator 5 are fixed together by a mounting base 2.

[0037] The mounting base 2 includes a connecting block 21, which is fixedly connected to the square cone 11 by commonly used bolts and nuts, or fixedly installed on the square cone 11 by welding.

[0038] After the connecting block 21 is installed, the base plate 22 is fixedly installed on the connecting block 21 by welding, with the connecting block 21 located at the center of the base plate 22. This allows the four sides of the base plate 22 to extend out, facilitating the later installation of the vibrator 5. After installation, the base plate 22 is parallel to the side plate of the square cone 11 it is located on.

[0039] A support plate 23 is vertically mounted at the bottom edge of the substrate 22. The support plate 23 is fixedly mounted to the middle of the bottom edge of the substrate 22 by welding. A positioning groove 24 is formed on the upper surface of the support plate 23. The groove opening of the horizontally arranged positioning groove 24 is parallel to the surface of the substrate 22 and is arranged upward.

[0040] Two lugs are fixedly installed at the middle of the upper edge of the substrate 22. An L-shaped pry bar 26 is hinged between the two lugs, which together form a hinge seat 25. The middle of the long section of the pry bar 26 is hinged to the substrate 22, and its short section forms the hook portion 261, so as to hook the vibrator 5 when installing it, thereby improving the ease of installation.

[0041] In use, the connecting block 21 and the base plate 22 are first fixedly installed on the square cone hopper 11. At this time, the pry bar 26 is flipped up, causing the permanent magnet on the hook portion 261 to adhere to the square cone hopper 11. Next, the vibrator 5 is lifted, and the lower edge of the vibrator base 51 is first placed into the positioning groove 24. Then, the vibrator base 51 is rotated upwards using the positioning groove 24 as a fulcrum. During rotation, the upper edge of the vibrator base 51 contacts the driving end of the pry bar 26, and as the vibrator base 51 rotates, the pry bar 26 is pushed and flipped over. The hook portion 261 of the pry bar 26 then flips to the back of the vibrator base 51. The vibrator 5 is then released, and it is suspended on the square cone hopper 11 by the engagement of the hook portion 261 and the positioning groove 24. There is a small gap between the vibrator base 51 suspended on the square cone hopper 11 and the base plate 22, preventing them from being completely locked in place. This facilitates the alignment and adjustment of the mounting holes 221 and through holes later.

[0042] Next, move the vibrator 5 left and right to align the mounting hole and the through hole. Then, insert the locking bolt 3 into the through hole and mounting hole 221, and gently push the vibrator 5 during insertion to allow the locking bolt 3 to pass smoothly through the through hole and mounting hole 221. During the pushing process, the permanent magnet magnetically attracts the hook part 261 to the vibrator base 51, so the vibrator 5 will not disengage and will always be in a hooked state. Finally, tighten the locking nut 4 onto the locking bolt 3, and the vibrator 5 can be fixedly installed on the square cone hopper 11, with the vibrator 5 located at the top-to-bottom quarter of the square cone hopper 11.

[0043] The vibrator 5 used in this application is model CZ250, and the inclined plate thickener 1 is model KMLZ-500-55.0.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
