Abstract
Description
Technical Field
[0001] This utility model relates to the field of solid-liquid separator technology, specifically to a screen for a solid-liquid separator. Background Technology
[0002] Solid-liquid separators are widely used in various industries (such as wastewater treatment, mining and metallurgy, chemical and oil extraction). They mainly separate solids and liquids through methods such as filtration, centrifugation, and sedimentation. For example, a solid-liquid separator with an inclined screen (application number: CN202022074136.0) disclosed in Chinese patent literature uses a vibrating motor to vibrate and screen the solid-liquid mixture, improving the screening quality. One end of the screen is fixed to a guide column by a fixed sleeve. During vibration, the screen itself undergoes a small displacement. The guide column and fixed sleeve limit the vibration of the screen, reducing the vibration effect. The installation of the vibrating motor increases the production cost of the separation equipment. The screen itself wears down over long-term use and needs to be replaced regularly. In addition, the screen is fixed by multiple sets of fixed columns and fixed sleeves, and each fixed sleeve needs to be removed when replacing the screen, extending the screen replacement time.
[0003] Therefore, we propose a screen for a solid-liquid separator. Utility Model Content
[0004] The purpose of this invention is to provide a screen for a solid-liquid separator to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a screen for a solid-liquid separator, comprising a frame, a feed pipe, and a first screen;
[0006] The mounting slot is located in the middle of the inner wall of the frame and is inclined.
[0007] The mounting shaft is located at the right end of the first screen, and both ends of the mounting shaft are installed into the mounting groove.
[0008] A pull ring is fixedly installed at the left end of the first screen.
[0009] A spring is located at the bottom left end of the first screen.
[0010] A support plate is fixedly connected to the bottom of the spring, and the left end of the support plate is fixedly connected to the frame.
[0011] The second screen is fixedly installed on the bottom right side of the frame;
[0012] The mounting port is located on the upper left side of the frame.
[0013] A fixing plate is installed inside the mounting opening;
[0014] The first threaded hole is located on the right side of the mounting port, and there are two sets of the first threaded hole, one upper and one lower.
[0015] Mounting holes are provided on the fixing plate, and there are two sets of mounting holes, one upper and one lower.
[0016] Bolts are installed in the mounting holes.
[0017] Preferably, the bottom of the frame is provided with a second threaded hole, and a nut is provided in the second threaded hole.
[0018] Preferably, the nut is provided with a pull rod, a bearing is provided between the nut and the pull rod, and a scraper is provided at the upper end of the pull rod.
[0019] Preferably, the bottom end of the spring is fixedly connected to the support plate, and the top end of the spring is movably connected to the bottom of the first screen.
[0020] Preferably, the bottom of the frame is inclined, and a liquid outlet is provided on the left side of the bottom of the frame.
[0021] Preferably, the mounting groove extends to the left into the mounting opening.
[0022] Preferably, the length of the bolt's threaded portion is less than the sum of the widths of the mounting hole and the first threaded hole.
[0023] Compared with the prior art, the beneficial effects of this utility model are:
[0024] 1. The solid-liquid mixture impacts the first screen. A spring at the bottom of the first screen is compressed under this impact. Since the spring can only store and release energy, it rebounds when it reaches its limit, causing the first screen to move slightly upwards. The first screen then rotates slightly via a mounting shaft at its right end. After releasing its energy, the spring continues to store and release energy under the impact of the solid-liquid mixture, causing the first screen to vibrate continuously. This improves the screening efficiency of the solid-liquid mixture and prevents the accumulation of solids in the mixture.
[0025] 2. By loosening the bolts, the fixing plate can be removed, the hook can be used to hang the pull ring, and the pull ring can be pulled to the left. The pull ring will move the first screen to the left, allowing for quick disassembly and replacement of the first screen. Attached Figure Description

[0032] 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.
[0033] Please see Figure 1-5This utility model provides a technical solution: a screen for a solid-liquid separator, comprising a frame 1, a feed pipe 2, a first screen 3, an installation groove 9 disposed in the middle of the inner wall of the frame 1, the installation groove 9 being inclined, an installation shaft 4 disposed at the right end of the first screen 3, with both ends of the installation shaft 4 installed into the installation groove 9, a pull ring 5 fixedly installed at the left end of the first screen 3, a spring 6 disposed at the bottom left end of the first screen 3, a support plate 7 fixedly connected to the bottom of the spring 6, the left end of the support plate 7 being fixedly connected to the frame 1, a second screen 8 fixedly installed at the bottom right side of the frame 1, an installation port 10 disposed at the upper left side of the frame 1, a fixing plate 11 installed in the installation port 10, a first threaded hole 12 disposed at the right side of the installation port 10, the first threaded hole 12 having two sets, upper and lower, an installation hole 13 disposed on the fixing plate 11, the installation hole 13 having two sets, upper and lower, and a bolt 14 installed in the installation hole 13. When solid-liquid separation is performed, the solid-liquid mixture enters the frame 1 through the feed pipe 2 and falls onto the first screen 3, the solid-liquid mixture reacts with the first screen... When the first screen 3 is impacted, the spring 6 at the bottom of the first screen 3 is compressed. Since the spring 6 can only store and release energy, it will rebound when it is compressed to its limit, causing the first screen 3 to move slightly upward. The first screen 3 rotates slightly through the mounting shaft 4 at its right end. After the spring 6 releases its energy, the first screen 3 continues to store and release energy under the impact of the solid-liquid mixture, thus causing the first screen 6 to vibrate continuously, improving the screening efficiency of the solid-liquid mixture. The vibration of the first screen 3 also prevents the accumulation of solids in the solid-liquid mixture. The first screen 3 is tilted so that after screening the solid-liquid mixture, the solids slide to the right side of the second screen 8 for temporary storage. The device can also remove the fixing plate 11 by loosening the bolt 14, hooking the pull ring 5, and pulling the pull ring 5 to the left. The pull ring 5 moves the first screen 3 to the left, allowing for quick disassembly and replacement of the first screen 3.
[0034] Reference embodiment: A second threaded hole 15 is provided at the bottom of the frame 1, and a nut 16 is provided in the second threaded hole 15. A pull rod 17 is provided on the nut 16, and a bearing 19 is provided between the nut 16 and the pull rod 17. A scraper 18 is provided at the upper end of the pull rod 17. The bottom of the frame 1 is inclined, and a liquid outlet is provided on the left side of the bottom of the frame 1. After opening the liquid outlet to discharge the liquid in the frame 1, the nut 16 is rotated and removed. The nut 16 is moved, and the nut 16 pulls the pull rod 17 through the bearing 19. The pull rod 17 pulls the scraper 18 downward. The scraper 18 cleans the solid between the second screen 8 and the frame 1 out of the frame 1, and quickly cleans the solid after screening.
[0035] Reference embodiment: The bottom end of the spring 6 is fixedly connected to the support plate 7, and the top end of the spring 6 is movably connected to the bottom of the first screen 3. The mounting groove 9 extends to the left into the mounting opening 10. When the first screen 3 is disassembled, the pull ring 5 drives the first screen 3 to move to the left, and the mounting shaft 4 slides to the left in the mounting groove 9 to disassemble the first screen 3. The spring 6 does not obstruct the disassembly of the first screen 3.
[0036] Reference embodiment: The length of the bolt 14 is less than the sum of the widths of the mounting hole 13 and the first threaded hole 12. When the bolt 14 passes through the mounting hole 13 and connects with the first threaded hole 12, tightening the bolt 14 fixes the fixing plate 11 to avoid gaps between the fixing plate 11 and the inner wall of the mounting opening 10.
[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
