Abstract
Description
Technical Field
[0001] This utility model relates to the field of concentration device technology, and more specifically, to a center-driven concentration device. Background Technology
[0002] In the solid-liquid separation process of industries such as mining, chemical industry, and environmental protection, the central drive thickening device is a key piece of equipment and is widely used in the thickening of suspensions such as mud and slurry. The device drives the scraper to rotate through the central drive system to scrape off the solid particles settled at the bottom of the tank, so as to prevent the slurry from settling and caking and improve the thickening efficiency, thereby achieving the purpose of solid-liquid separation and thickening.
[0003] Currently, most scrapers used in existing central drive thickening devices are fixedly installed, typically by bolts connecting the scraper to the transmission components. After prolonged use, the scraper wears down due to continuous friction with the solid particles settled at the bottom of the tank, requiring periodic replacement. However, this bolted structure makes scraper disassembly cumbersome, requiring wrenches and other tools, consuming significant time and manpower, severely impacting the continuous operation efficiency of the equipment. Furthermore, due to the inconvenience of disassembly, some operators choose to delay scraper replacement, which not only reduces the efficiency of the thickening device but may also prevent the solid particles settled at the bottom of the tank from being effectively scraped away, thus affecting the solid-liquid separation effect and product quality. Therefore, improvements are needed. Utility Model Content
[0004] In order to overcome the shortcomings of the prior art, this utility model provides a central drive concentration device, which has the advantage of being able to easily disassemble and assemble the scraper.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a centrally driven concentration device, comprising:

A square insert rod is slidably connected inside the square groove, and the outer surface of the square insert rod is movably sleeved with the interior of the outer surface of the connecting column. A threaded block is fixedly installed at the end of the square insert rod away from the square groove. A rotating block is threadedly sleeved on the outer surface of the threaded block, and round blocks are movably sleeved at both ends of the rotating block.

[0022] 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.
[0023] like Figures 1 to 5 As shown, this utility model provides a center-driven concentration device, comprising:
[0024] Fixed sleeve 1, a rotating frame 2 is fixedly installed on the outer surface of fixed sleeve 1, and a connecting column 3 is fixedly installed at the bottom end of rotating frame 2;
[0025] The disassembly and assembly mechanism is located inside the connecting column 3;
[0026] The disassembly and assembly mechanism includes a square rod 4, the outer surface of which is movably sleeved with the interior of the connecting column 3. A square groove 5 is provided on the square rod 4. A scraper 6 is fixedly installed at the bottom end of the square rod 4. A material tank 7 is slidably connected to the bottom end of the scraper 6. A square insert rod 8 is slidably connected inside the square groove 5. The outer surface of the square insert rod 8 is movably sleeved with the interior of the outer surface of the connecting column 3. A threaded block 9 is fixedly installed at the end of the square insert rod 8 away from the square groove 5. A rotating block 10 is threadedly sleeved on the outer surface of the threaded block 9. Both ends of the rotating block 10 are movably sleeved with round blocks 11. The outer surface of the round blocks 11 is fixedly connected to the outer surface of the connecting column 3.
[0027] Because the circular block 11 is movably connected to the rotating block 10, the rotating block 10 can rotate along the inside of the circular block 11. Due to the design of the circular block 11, it can provide good support for the rotating block 10, making the rotating block 10 more stable when rotating. Because the inside of the rotating block 10 is threadedly connected to the threaded block 9, when the rotating block 10 rotates, it will drive the two square insert rods 8 to move through the two threaded blocks 9. At this time, the two square insert rods 8 will move towards each other along the inside of the two square grooves 5. When the two square insert rods 8 release their contact with the inside of the square grooves 5 during the movement, the two square insert rods 8 will no longer be able to lock the square rod 4, thus allowing the operator to remove the worn scraper 6.
[0028] Among them, a rotating block 12 is fixedly sleeved on the outer surface of the rotating block 10, and a protrusion is provided on the rotating block 12.
[0029] When the operator turns the turning block 12, the turning block 12 will drive the rotating block 10 to rotate. Since the outer surface of the turning block 12 is provided with protrusions, the friction of the outer surface of the turning block 12 can be increased, so that the operator can turn the turning block 12.
[0030] The bottom of the material tank 7 is fixedly installed with a column 13, and a reinforcing rod 14 is provided on the column 13.
[0031] The design of the column 13 provides good support for the entire material tank 7, allowing the material tank 7 to be placed stably on the ground. The design of the reinforcing rod 14 enhances the structural strength of the column 13.
[0032] The top plate 15 is fixedly installed on the top of the material tank 7, and the guardrail 16 is fixedly installed on the top of the top plate 15.
[0033] The design of the top plate 15 makes it easy for operators to climb to the top of the material tank 7 to observe the slurry, and the design of the guardrail 16 provides good protection for the operators.
[0034] Among them, a baffle 17 is fixedly sleeved inside the top of the top plate 15, a support block 18 is fixedly installed inside the baffle 17, a circular plate 19 is fixedly installed at the end of the support block 18 away from the support block 18, a motor 20 is fixedly installed at the top of the circular plate 19, a rotating shaft 21 is fixedly sleeved at the output end of the motor 20, a square shaft 22 is fixedly sleeved at the bottom end of the rotating shaft 21, the outer surface of the square shaft 22 is slidably sleeved with the inside of the fixed sleeve 1, and a support plate 23 is movably sleeved at the bottom end of the square shaft 22. The support plate 23 is fixedly connected to the inside of the bottom end of the material tank 7.
[0035] Due to the design of the baffle 17, support block 18 and circular plate 19, the motor 20 will be well supported. When the motor 20 runs, the rotating shaft 21 will drive the square shaft 22 to rotate. At this time, the square shaft 22 will drive the fixed sleeve 1 to move as a whole. Since the fixed sleeve 1 is movably connected to the square shaft 22, the fixed sleeve 1 can move up and down along the outer surface of the square shaft 22. Due to the design of the support plate 23, the square shaft 22 will be well supported as a whole.
[0036] The bottom of the material tank 7 is fixedly equipped with a discharge pipe 24, and a valve 25 is installed on the discharge pipe 24.
[0037] Due to the design of the discharge pipe 24, the concentrated slurry inside the material tank 7 can be discharged through the discharge pipe 24. Due to the design of the valve 25, it is convenient for operators to control the opening and closing of the discharge pipe 24.
[0038] Working principle and usage process of this utility model:
[0039] When the operator needs to concentrate the slurry, the operator first pours the slurry into the tank 7 and adds flocculant. Then, the operator starts the motor 20. At this time, the rotating shaft 21 drives the fixed sleeve 1 to rotate through the square shaft 22. Then, the fixed sleeve 1 drives the two sets of connecting columns 3 to rotate through the two rotating frames 2. At this time, the two sets of connecting columns 3 drive the two sets of scrapers 6 to rotate through the two sets of square rods 4. During this process, the two sets of scrapers 6 can continuously scrape the bottom of the tank 7, thereby preventing the slurry from settling and hardening. The agitation of the scrapers 6 can also disturb the sediment layer, making it easier for the free water mixed in the slurry to be discharged through the upper clear liquid, thereby improving the dewatering efficiency of the thickening device and making the concentration of the underflow slurry higher. After the slurry is concentrated, the operator opens the valve 25, and the concentrated slurry in the tank 7 will be discharged through the discharge pipe 24.
[0040] After prolonged use, scraper 6 will wear out, requiring replacement by the operator. First, the operator lifts the rotating frame 2, causing it to move the fixed sleeve 1 upwards along the outer surface of the square shaft 22. Next, the operator turns the turning block 12, causing the rotating block 10 to rotate. Since the rotating block 10 is threadedly connected to the outer surface of the threaded block 9, its rotation drives the two square insert rods 8 via the two threaded blocks 9. The two square insert rods 8 then move towards each other along the interior of the two square grooves 5 under the influence of the two threaded blocks 9. Subsequently, the two square insert rods 8 disengage during this movement. When the two square rods 8 come into contact with the inside of the square groove 5, they will no longer be able to lock the square rod 4, allowing the operator to remove the scraper 6 from the rotating frame 2. When the operator needs to install the scraper 6, the operator holds the scraper 6 and inserts the square rod 4 at its top into the inside of the connecting column 3. When the inside of the square groove 5 is aligned with the square rod 8, the operator turns the turning block 12 in the opposite direction. At this time, the two square rods 8 will move in opposite directions and then insert into the inside of the square groove 5, thereby locking the square rod 4 inside the connecting column 3, thus completing the installation of the scraper 6 and realizing the function of convenient scraper installation and removal.
