Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, and more specifically, to a heavy medium high-speed precipitation device which is easy to transport. Background Art

[0002] In the water treatment process, in order to better separate water and insoluble pollutants, the loaded sedimentation process is usually adopted. The loaded sedimentation process is based on the traditional coagulation sedimentation process. By adding fine particles with a larger specific gravity - heavy medium into the sewage, under the action of coagulants and coagulant aids, the added heavy medium combines with the insoluble pollutants in the water to form flocs with a higher density, thereby accelerating sedimentation and improving sedimentation efficiency.

[0003] The existing mechanism separates heavy medium and sludge by cyclone separation, while magnetic heavy medium mostly separates heavy medium and sludge by magnetic separation. However, cyclone separation has limited destructive power on flocs and is not efficient, while magnetic separation is expensive.

[0004] After searching, the Chinese patent with the authorization announcement number CN216537036U discloses a heavy medium deflocculation and recovery device. The mechanism uses a high-speed dispersing deflocculator in the deflocculation area to stir and separate the flocs at high speed. After stirring and separation, the flocs are deflocculated and separated into heavy medium and light sludge, and enter the sedimentation separation area through the deflocculation liquid outlet. In the sedimentation separation area, the heavy medium settles downward by its own gravity and is concentrated in the heavy medium concentration area; while the light sludge floats up and is collected through an annular liquid collecting tank and discharged through a liquid outlet pipe located on the side of the annular liquid collecting tank. Compared with the cyclone deflocculation effect, the heavy medium recovery rate is higher; compared with the magnetic separation structure, the structure is simpler and the cost is lower; the flocs are centrally deflocculated in the inner cylinder by the high-speed dispersing deflocculator, so that the deflocculation effect is better and the centralized recovery of the heavy medium is achieved.

[0005] However, in actual use, the structure is an integral structure with a fixed design and cannot be disassembled. It is difficult to decompose it into parts that are easy to transport, resulting in low transportation efficiency. If it is disassembled, it may cause damage to the structure and performance of the device. Utility Model Content

The material of the coagulant is aluminum salt or iron salt, etc. The function of these coagulants is to make the suspended matter and colloidal particles in the raw water lose stability, prepare for the subsequent flocculation reaction, and start the liquid inlet. The second motor 21 at the top of the shell 4 drives the rotating rod 22 and the stirring drum 23 to rotate, thereby driving the stirring blade 24 to rotate for rapid stirring, so that the coagulant and the raw water are fully mixed, ensuring that the coagulant can act evenly on the suspended matter and colloidal particles in the raw water. The residence time is about 1-2 minutes. Through this step, the tiny particles in the raw water are initially gathered together and then enter the interior of the stirring shell 6. Then, micro-sand and polymer flocculant are added through the feeding pipe. The micro-sand is the heavy medium as the core of the flocculation reaction, providing a basis for the formation of flocs. By starting the second motor 21 at the top of the stirring shell 6, the rotating rod 22 and the stirring drum 23 are driven to rotate, thereby driving the stirring blade 24 to rotate for rapid stirring, accelerating the aggregation between them, and forming high-density flocs with high density and heavy mass. The micro-sand is wrapped inside the flocs or attached to the surface of the flocs, increasing the weight of the flocs and making them easier to settle.

[0025] Reference Figure 2-3As shown, the disassembly mechanism includes a first sealing gasket 9 fixedly arranged on one side of the liquid inlet shell 4 and the sedimentation shell 8, a second sealing gasket 10 is fixedly arranged on both sides of the stirring shell 6, a first flange 11 is connected between the liquid inlet shell 4 and the stirring shell 6 by bolts, a second flange 12 is connected between the stirring shell 6 and the sedimentation shell 8 by bolts, a fixing frame 13 is threadedly connected to the top of the sedimentation shell 8, a first motor 14 is fixedly arranged inside the fixing frame 13, a rotating shaft 15 is fixedly arranged on the output end of the first motor 14, and a rotating shaft 15 is fixedly arranged on the output end of the rotating shaft 15. The bottom is threadedly connected with a threaded sleeve 16, and two arc-shaped bars 17 are fixedly provided on the surface of the threaded sleeve 16. A plurality of fixing rods 18 are fixedly provided on the tops of the two arc-shaped bars 17. An inclined tube 19 is fixedly provided inside the sedimentation shell 8. One end of the rotating shaft 15 passes through the sedimentation shell 8 and extends to the inside of the sedimentation shell 8. One end of the rotating shaft 15 passes through the inclined tube 19 and extends to the outside of the inclined tube 19. The sedimentation shell 8 and the inclined tube 19 are both rotatably connected to the rotating shaft 15. When the arc-shaped bars 17 and the fixing rods 18 need to be replaced, first rotate one side of the second flange 12 The bolts are tightened, thereby driving the second sealing gasket 10 and the first sealing gasket 9 to separate, thereby opening the stirring shell 6 and the sedimentation shell 8, and since the rotation direction of the threaded sleeve 16 and the rotating shaft 15 is opposite to the rotation direction of the rotating shaft 15 driven by the first motor 14, the rotating shaft 15 will not cause the threaded sleeve 16 to fall off during the rotation process. Then, the threaded sleeve 16 at the bottom is rotated forward, thereby driving the threaded sleeve 16 to separate from the rotating shaft 15, and then the arc strip 17 is removed for replacement, and then the installation operation is reversed according to the above steps. The stirring blade 24 is removed and replaced. The rotation direction of the stirring drum 23 and the rotating rod 22 is opposite to the rotation direction of the rotating rod 22 driven by the second motor 21. Therefore, the stirring drum 23 driven by the rotating rod 22 will not fall off during the rotation process, which is convenient for disassembly and assembly during transportation.

[0026] Reference Figure 4-5As shown, the tops of the liquid inlet shell 4 and the stirring shell 6 are connected to a stabilizing frame 20 by bolts, and the interior of the stabilizing frame 20 is fixedly connected to a second motor 21, and the output end of the second motor 21 is fixedly provided with a rotating rod 22, and the surface of the rotating rod 22 is threadedly connected to a stirring drum 23, and the surface of the stirring drum 23 is fixedly provided with a plurality of stirring blades 24. The bottom of the sedimentation shell 8 is fixedly provided with an arc-shaped bottom plate 25, and a circulating sludge pump is installed on one side of the arc-shaped bottom plate 25, and then enters the interior of the sedimentation shell 8. Due to the high density and heavy mass of the flocs, the flocs can sink quickly under the action of gravity and separate from the water. At the same time, the presence of the inclined tube 19 makes the water flow form a relatively stable flow state during the rising process, which is conducive to the sedimentation of the flocs. The sludge and micro-sand settled at the bottom of the sedimentation tank are pumped out by the circulating sludge pump. By starting the first motor 14 to drive the rotating shaft 15 to rotate, the rotating shaft 15 drives the threaded sleeve 16 and the arc bar 17 to rotate, and the arc bar 17 drives the fixed rod 18 to rotate. As the liquid flows, the clear liquid gradually rises and generates an axial force in the vertical and downward direction, which is conducive to the sedimentation of flocs in the water body, and the precipitated suspended matter gathers at the bottom of the sedimentation shell 8. During the sedimentation process, the arc bar 17 and the fixed rod 18 play a role in guiding the water flow and preventing the water flow from short-circuiting, so that the liquid can fully contact the heavy medium to ensure the sedimentation effect.

[0027] Working principle of this utility model:

[0028] The utility model is a heavy medium high-speed sedimentation device that is easy to transport. When the device is in use, the raw water enters the interior of the liquid inlet shell 4 through the feed pipe, and a coagulant is added. The material of the coagulant is aluminum salt or iron salt, etc. The function of these coagulants is to make the suspended matter and colloidal particles in the raw water lose stability, so as to prepare for the subsequent flocculation reaction, and by starting the second motor 21 on the top of the liquid inlet shell 4 to drive the rotating rod 22 and the stirring drum 23 to rotate, thereby driving the stirring blade 24 to rotate and quickly stirring, so that the coagulant and the raw water are fully mixed, ensuring that the coagulant can evenly act on the suspended matter and colloidal particles in the raw water. The stirring time is about 1-2 minutes. Through this step, the tiny particles in the raw water are initially gathered together and then enter the interior of the stirring shell 6. Then, micro sand and high molecular flocculant are added through the feeding pipe. The micro sand is the heavy medium and serves as the core of the flocculation reaction, providing a basis for the formation of flocs. The second motor 21 on the top of the stirring shell 6 is started to drive the rotating rod 22 and the stirring drum 23 to rotate, thereby driving the stirring blade 24 to rotate, performing rapid stirring, accelerating the aggregation between them, and forming high-density flocs with large density and heavy mass. The micro sand is wrapped inside the flocs or attached to the surface of the flocs, increasing the weight of the flocs and making them easier to settle.

[0029] Then it enters the interior of the sedimentation shell 8. Due to the high density and heavy mass of the flocs, the flocs can sink quickly under the action of gravity and separate from the water. At the same time, the presence of the inclined tube 19 allows the water flow to form a relatively stable flow state during the rising process, which is conducive to the sedimentation of the flocs. The sludge and micro-sand settled at the bottom of the sedimentation tank are pumped out by the circulating sludge pump. By starting the first motor 14 to drive the rotating shaft 15 to rotate, the rotating shaft 15 drives the threaded sleeve 16 and the arc bar 17 to rotate, and the arc bar 17 drives the fixed rod 18 to rotate. As the liquid flows, the clear liquid gradually rises and generates an axial force in the vertical and downward direction, which is conducive to the sedimentation of flocs in the water body, and the precipitated suspended matter gathers at the bottom of the sedimentation shell 8. During the sedimentation process, the arc bar 17 and the fixed rod 18 play the role of guiding the water flow and preventing the water flow from short-circuiting, so that the liquid can fully contact the heavy medium to ensure the sedimentation effect.

[0030] When the arc strip 17 and the fixing rod 18 need to be replaced, first rotate the bolt on one side of the second flange 12 to drive the second sealing gasket 10 and the first sealing gasket 9 to separate, thereby opening the mixing shell 6 and the sedimentation shell 8. Since the rotation direction of the threaded sleeve 16 and the rotating shaft 15 is opposite to the rotation direction of the rotating shaft 15 driven by the first motor 14, the rotating shaft 15 will not drive the threaded sleeve 16 to fall off during the rotation process. Then rotate the threaded sleeve 16 at the bottom in the forward direction to drive the threaded sleeve 16 to separate from the rotating shaft 15, and then remove the arc strip 17 for replacement. , and then perform the installation operation in reverse according to the above steps, and rotate the bolts on one side of the first flange 11 to drive the liquid inlet shell 4 and the stirring shell 6 to separate, then rotate the stirring drum 23 in the forward direction to drive the stirring drum 23 to separate from the rotating rod 22, and drive the stirring blade 24 to be removed for replacement, and because the rotation direction of the stirring drum 23 and the rotating rod 22 is opposite to the rotation direction of the rotating rod 22 driven by the second motor 21, the rotating rod 22 will not cause the stirring drum 23 to fall off during the rotation process, which is convenient for disassembly and assembly during transportation, and it is more convenient to disassemble and assemble.

[0031] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
