AI Technical Summary
[0003]重介质在使用后直接排放会造成浪费，而现有的磁选机在重介质回收过程中存在明显缺陷：在磁选过程中，磁系依靠强大的磁力吸引重介质，使重介质吸附在转筒外壁，实现与溶液的初步分离；但由于重介质吸附过程快速且缺乏精细筛选，在吸附瞬间，重介质很可能会裹挟非重介质的杂质，导致回收效率较低
[0016]本实用新型的有益技术效果：按照本实用新型的洗选煤炭用重介质回收装置，通过设置磁系机构、转筒、煤泥斗和重介质斗，磁系机构偏向加注口，并且固定不动，电机带动转筒沿煤泥斗向重介质斗转动，洗煤后的水通入加注口落在转筒上，其中的重介质被磁系机构吸附在转筒上，在转动至底端时，煤泥在重力作用下落在煤泥斗中，其中的重介质被磁系机构吸附在转筒上继续转动至重介质斗上，此时吸附在转筒上的重介质脱离磁系机构，在重力作用下进入重介质斗中，从而回收利用；通过设置漏斗和若干个分流管，使得煤水能够均布在转筒上，配合刮板，从而使得煤水均布在转筒上，摊薄煤水，从而防止由于磁系机构吸附力较大导致裹挟煤泥进入重介质斗，从而提高回收效率。

Abstract
Description
Technical Field
[0001] This utility model relates to a heavy medium recovery device for coal washing, belonging to the technical field of heavy medium recovery equipment for coal washing. Background Technology
[0002] The heavy medium recovery device for coal washing is a key piece of equipment in the coal washing and processing process. Its main function is to efficiently recover heavy media from the solution after coal washing. In the coal washing process, heavy media acts as a "separating agent," mixing with coal particles and using density differences to separate clean coal from impurities such as gangue. The recovery device can separate the used heavy media from the solution, purify it, and recycle it. This not only reduces production costs but also reduces resource waste, which is of great significance for improving the efficiency and quality of coal washing.
[0003] Directly discharging heavy media after use would be wasteful, and existing magnetic separators have obvious defects in the heavy media recovery process: during the magnetic separation process, the magnetic system relies on strong magnetic force to attract heavy media, causing the heavy media to be adsorbed on the outer wall of the rotating drum, achieving preliminary separation from the solution; however, due to the rapid adsorption process of heavy media and the lack of fine screening, the heavy media may carry away non-heavy media impurities at the moment of adsorption, resulting in low recovery efficiency.
[0004] Therefore, this utility model proposes a new solution. Utility Model Content
[0005] The main purpose of this utility model is to provide a heavy medium recovery device for coal washing and processing in order to overcome the shortcomings of the existing technology.
[0006] The objective of this utility model can be achieved by adopting the following technical solution:
[0007] A heavy medium recovery device for coal washing includes a recovery box, a fixed rod fixedly connected to the middle of the recovery box, an arc-shaped magnetic mechanism fixedly installed on the outer wall of the fixed rod, a motor installed on the front outer wall of the recovery box, the output end of the motor connected to a rotating drum located outside the magnetic mechanism, a filling port fixedly connected to one side of the top of the recovery box, a coal slurry hopper located below the filling port and a heavy medium hopper located to one side of the coal slurry hopper at the bottom of the recovery box, a discharge pipe fixedly connected to the bottom of both the coal slurry hopper and the heavy medium hopper, a valve installed on the discharge pipe, the magnetic mechanism biased towards the filling port, a funnel installed in the middle of the filling port, a plurality of diversion pipes connected to the bottom end of the funnel, and a scraper fixedly connected to the bottom of the filling port.
[0008] Preferably, a partition cone is fixedly connected to the bottom inner wall of the recycling bin, located between the coal slime hopper and the heavy medium hopper.
[0009] Preferably, an edge plate located at the top of the filling port is fixedly connected to the top outer wall of the funnel.
[0010] Preferably, the top of the recycling bin is provided with a maintenance port located on one side of the filling port.
[0011] Preferably, the top of the recycling bin is fitted with a maintenance door via a hinge, and the maintenance door is fitted with a handle.
[0012] Preferably, the magnetic system mechanism has several sleeves at its axis, and several connecting rods connect the sleeves and the magnetic system mechanism. The sleeves and the fixing rods are connected to each other by bolts.
[0013] Preferably, the sleeve has a first connecting hole in the middle, and the fixing rod has a second connecting hole corresponding to the first connecting hole.
[0014] Preferably, the rotating drum includes a drum body and a drum cover connected by bolts, and a first sealing ring is installed between the drum body and the drum cover.
[0015] Preferably, the cylinder has a mounting hole in the middle, and a second sealing ring located on the outer wall of the fixing rod is installed on the inner wall of the mounting hole.
[0016] The beneficial technical effects of this utility model are as follows: According to the heavy medium recovery device for coal washing of this utility model, a magnetic system, a rotating drum, a coal slurry hopper, and a heavy medium hopper are set up. The magnetic system is biased towards the filling port and remains stationary. The motor drives the rotating drum to rotate along the coal slurry hopper towards the heavy medium hopper. Water from coal washing flows into the filling port and falls onto the rotating drum. The heavy medium is attracted to the rotating drum by the magnetic system. When rotating to the bottom, the coal slurry falls into the coal slurry hopper under gravity, and the heavy medium is attracted to the rotating drum by the magnetic system and continues to rotate to the heavy medium hopper. At this point, the heavy medium attracted to the rotating drum detaches from the magnetic system and enters the heavy medium hopper under gravity, thus being recovered and reused. By setting up a funnel and several diversion pipes, the coal and water can be evenly distributed on the rotating drum. Combined with a scraper, the coal and water are evenly distributed on the rotating drum, thinning the coal and water, thus preventing coal slurry from being carried into the heavy medium hopper due to the large attraction force of the magnetic system, thereby improving the recovery efficiency.

[0024] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.
[0025] like Figures 1-6As shown, the heavy medium recovery device for coal washing provided in this embodiment includes a recovery box 1. A fixed rod 2 is fixedly connected to the middle of the recovery box 1. An arc-shaped magnetic mechanism 3 is fixedly installed on the outer wall of the fixed rod 2. A motor 4 is installed on the front outer wall of the recovery box 1. The output end of the motor 4 is connected to a rotating drum 5 located outside the magnetic mechanism 3. A filling port 6 is fixedly connected to one side of the top of the recovery box 1. The bottom of the recovery box 1 is provided with a coal slurry hopper 7 located below the filling port 6 and a heavy medium hopper 8 located on one side of the coal slurry hopper 7. Both the bottom of the coal slurry hopper 7 and the heavy medium hopper 8 are fixedly connected to a discharge pipe 9. A valve is installed on the discharge pipe 9. The magnetic mechanism 3 is biased towards the filling port 6. A funnel 11 is installed in the middle of the filling port 6. Several diversion pipes 12 are connected to the bottom of the funnel 11. A scraper 18 is fixedly connected to the bottom of the filling port 6. By setting up a magnetic system mechanism 3, a rotating drum 5, a coal slurry hopper 7, and a heavy medium hopper 8, the magnetic system mechanism 3 is biased towards the filling port 6 and remains stationary. The motor 4 drives the rotating drum 5 to rotate along the coal slurry hopper 7 towards the heavy medium hopper 8. Water after coal washing flows into the filling port 6 and falls onto the rotating drum 5. The heavy medium in the water is attracted onto the rotating drum 5 by the magnetic system mechanism 3. When rotating to the bottom, the coal slurry falls into the coal slurry hopper 7 under the action of gravity. The heavy medium in the water is attracted onto the rotating drum 5 by the magnetic system mechanism 3 and continues to rotate to the heavy medium hopper 8. At this time, the heavy medium attracted onto the rotating drum 5 detaches from the magnetic system mechanism 3 and enters the heavy medium hopper 8 under the action of gravity, thus being recycled. By setting up a funnel 11 and several diversion pipes 12, the coal water can be evenly distributed on the rotating drum 5. With the help of the scraper 18, the coal water is evenly distributed on the rotating drum 5, spreading the coal water thinly, thereby preventing the coal slurry from being carried into the heavy medium hopper 8 due to the large adsorption force of the magnetic system mechanism 3, thus improving the recovery efficiency.
[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, a partition cone 10 is fixedly connected to the bottom inner wall of the recovery box 1, located between the coal slime hopper 7 and the heavy medium hopper 8. By setting the partition cone 10, the coal slime can be blocked, thereby improving the recovery efficiency of the heavy medium.
[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 6 As shown, an edge plate 13 located at the top of the filling port 6 is fixedly connected to the top outer wall of the funnel 11. The edge plate 13 is used to install the funnel 11.
[0028] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the top of the recycling bin 1 has a maintenance port 14 located on one side of the filling port 6. A maintenance door 15 is hinged to the top of the recycling bin 1, and a handle 16 is installed on the maintenance door 15. The maintenance port 14 and maintenance door 15 facilitate installation and maintenance.
[0029] In this embodiment, as Figure 1 , Figure 3 and Figure 4 As shown, the magnetic system mechanism 3 has several sleeves 301 at its axis, and several connecting rods 302 connect the sleeves 301 and the magnetic system mechanism 3. The sleeves 301 and the fixing rods 2 are connected to each other by bolts. The middle of the sleeve 301 has a first connecting hole 303, and the fixing rod 2 has a second connecting hole 201 corresponding to the first connecting hole 303. By setting up the sleeves 301, the first connecting hole 303, the second connecting hole 201, and the bolts, the connection and installation can be carried out using bolts, thus enabling quick assembly and disassembly.
[0030] In this embodiment, as Figure 1 , Figure 3 and Figure 5 As shown, the rotating drum 5 includes a drum body 501 and a drum cover 502 connected by bolts. A first sealing ring 17 is installed between the drum body 501 and the drum cover 502. A mounting hole 503 is provided in the middle of the drum body 501, and a second sealing ring 504 located on the outer wall of the fixing rod 2 is installed on the inner wall of the mounting hole 503. The rotating drum 5 includes a drum body 501 and a drum cover 502 connected by bolts, which is convenient for loading and unloading. By providing the mounting hole 503 and the second sealing ring 504, leakage can be prevented when the rotating drum 5 rotates.
[0031] In this embodiment, as Figures 1-6 As shown in the figure, the working process of the heavy medium recovery device for coal washing provided in this embodiment is as follows:
[0032] The starting motor 4 drives the rotating drum 5 to rotate along the coal slurry hopper 7 towards the heavy medium hopper 8. Water after coal washing enters the filling port 6 and falls onto the rotating drum 5. The heavy medium is attracted onto the rotating drum 5 by the magnetic mechanism 3. When rotating to the bottom, the coal slurry falls into the coal slurry hopper 7 under the action of gravity. The heavy medium is attracted onto the rotating drum 5 by the magnetic mechanism 3 and continues to rotate to the heavy medium hopper 8. At this time, the heavy medium attracted onto the rotating drum 5 detaches from the magnetic mechanism 3 and enters the heavy medium hopper 8 under the action of gravity, thus being recycled.
