Abstract
Description
Technical Field
[0001] This utility model relates to the field of mixing equipment technology, and in particular to a mud mixing equipment. Background Technology
[0002] Rock salt is primarily extracted through well drilling, where fresh water is injected into a well to dissolve the salt, and brine is extracted. This brine is then sent to a chlor-alkali company for further treatment. The wastewater and impurities, such as salt sludge, generated after treatment are sent to a desalination tank, from which it is then injected into the well using a submersible pump. To prevent the deposition of salt sludge and other impurities in the desalination tank, compressed air agitation is often used; however, this easily creates salt mist, which can harm surrounding equipment and the environment. Existing submersible pumps typically have agitator blades at the inlet, providing some agitation, but the agitation range is limited. Since desalination tanks are usually large, salt sludge can still accumulate in un-aggregated areas. Installing a separate, motor-driven agitator would be too costly. Utility Model Content
[0003] This utility model proposes a mud mixing device that, through the cooperation of a mobile submersible pump, a Y-type filter and a bottom mixing component, avoids the deposition of impurities such as salt mud. The mobile submersible pump can be used alternately or simultaneously for mud discharge and well injection as well as water pumping and mixing. Two submersible pumps can meet the mud discharge and well injection needs of large-size brine tanks.
[0004] The technical solution of this utility model is implemented as follows: A mud mixing device includes a bottom mixing assembly, a bottom submersible pump, and a vertically adjustable movable submersible pump installed in a brine tank. The outlet of the movable submersible pump is connected to the inlet of a Y-type filter. The bottom mixing assembly includes a hollow shaft with a rotating bushing on it. A hollow mixing blade is fixed on the bushing. A water outlet is provided on the same side wall of the mixing blade. The outlet of the Y-type filter is connected to the hollow shaft, and the hollow shaft is connected to the inner cavity of the mixing blade. The outlet of the bottom submersible pump is connected to a mud discharge pipe.
[0005] Furthermore, the outlet of the active submersible pump is connected to a first pipe and a second pipe. The first pipe is connected to the inlet of the Y-type filter, and the second pipe is connected to the sludge discharge pipe. A first control valve is installed on both the first pipe and the second pipe.
[0006] Furthermore, a vertical guide rail is fixed inside the brine tank, and a sliding support is provided on the vertical guide rail, with the movable submersible pump fixed on the support.
[0007] Furthermore, the drain outlet of the Y-type filter is equipped with a drain valve, which is connected to the bottom of the brine tank through a drain pipe.
[0008] Furthermore, the Y-type filter is equipped with a drain valve at its drain outlet, which is connected to the sludge discharge pipe via a drain pipe.
[0009] Furthermore, the outlet of the Y-type filter is connected to the hollow shaft via a third pipe, and a second control valve is installed on the third pipe.
[0010] Furthermore, the bottom stirring assembly includes multiple components, which are evenly distributed at the bottom of the brine tank.
[0011] Furthermore, a through hole is provided on the side wall of the hollow shaft, and an annular cavity is provided on the bushing. The annular cavity communicates with the through hole and with the inner cavity of the stirring blade.
[0012] The beneficial effects of this utility model are:
[0013] This invention utilizes a combination of a mobile submersible pump, a Y-type filter, and a bottom stirring assembly to extract upper-layer brine to flush and stir the bottom of the brine tank, preventing the deposition of impurities such as salt mud. Simultaneously, the bottom submersible pump injects the salt mud from the bottom of the brine tank into the well. The mobile submersible pump can also be adjusted in height as needed, and can be used alternately or simultaneously for mud discharge, well injection, and water pumping and stirring. By using two submersible pumps, the mud discharge and well injection needs of large-sized brine tanks can be met, eliminating the need for a separate motor-driven stirring device and reducing costs.
[0014] This utility model's Y-type filter can filter the light brine drawn by a mobile submersible pump, reducing the likelihood of clogging the bottom stirring assembly. The drain port of the Y-type filter is connected to the bottom of the light brine tank, facilitating the return of the salt mud impurities trapped by the Y-type filter to the tank. Alternatively, the drain port of the Y-type filter can be connected to a mud discharge pipe, allowing the trapped salt mud to be directly pumped to the mud discharge pipe for injection into the well via the mobile submersible pump.

[0021] 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.
[0022] Example 1
[0023] like Figure 1 As shown, a mud mixing device includes a bottom mixing assembly 1, a bottom submersible pump 2, and a vertically adjustable movable submersible pump 3. The bottom mixing assembly 1 and the bottom submersible pump 2 are both fixed to the bottom of a brine tank 13. Multiple bottom mixing assemblies 1 can be installed as needed, and these assemblies are evenly distributed at the bottom of the brine tank 13. The bottom submersible pump 2 is located above the bottom mixing assembly 1. The bottom submersible pump 2 and the movable submersible pump 3 are located on opposite sides of the brine tank 13.
[0024] A vertical guide rail 4 is fixed inside the brine tank 13. A sliding support 5 is provided on the vertical guide rail 4. The movable submersible pump 3 is fixed on the support 5. The support 5 is connected to a lifting device such as an electric hoist. The movable submersible pump 3 is driven to move along the vertical guide rail 4 through the support 5, so that the height of the movable submersible pump 3 in the brine tank 13 can be adjusted as needed.
[0025] The outlet of the submersible pump 3 is connected to a first pipe 6 and a second pipe 7. The first pipe 6 is connected to the inlet of the Y-type filter 8, and the second pipe 7 is connected to the sludge discharge pipe 9. A first control valve 10 is installed on both the first pipe 6 and the second pipe 7. The first control valve 10 can be an electric valve or a manual valve, etc. The drain port of the Y-type filter 8 is connected to a drain valve 11. The drain valve 11 is connected to the bottom of the brine tank 13 through a drain pipe 12. The drain valve 11 can be opened periodically as needed to return the brine slurry in the Y-type filter 8 to the brine tank 13. The outlet of the bottom submersible pump 2 is connected to the sludge discharge pipe 9.
[0026] like Figure 1 , 2As shown in Figure 3, the bottom stirring assembly 1 includes a hollow shaft 14. A through hole 15 is provided on the side wall of the hollow shaft 14. A bushing 16 is rotatably connected to the hollow shaft 14 via a bearing. An annular cavity 17 is provided on the bushing 16, communicating with the through hole 15. A hollow stirring blade 18 is fixed on the bushing 16. The annular cavity 17 communicates with the inner cavity of the stirring blade 18. A water outlet 19 is provided on the same side wall of the stirring blade 18, such that all the water outlets 19 of the stirring blade 18 are located on the same side wall. The other side wall of the stirring blade 18 is a closed structure. The outlet of the Y-type filter 8 is connected to the hollow shaft 14 via a third pipe 21.
[0027] The method of using the mud mixing equipment is as follows: Adjust the height of the movable submersible pump 3 so that it is located on the upper side inside the brine tank 13. Open the first control valve 10 on the first pipe 6. The movable submersible pump 3 draws the brine from the upper side. After being filtered by the Y-type filter 8, it is sent to the hollow shaft 14, enters the inner cavity of the mixing blade 18 through the through hole 15 and the annular cavity 17, and then is discharged through the water outlet 19. When the brine is discharged, it will rotate the mixing blade 18 in a circumferential direction, thereby stirring the salt mud at the bottom of the brine tank 13 to prevent the salt mud from settling to the bottom. The bottom submersible pump 2 draws the salt mud water from the bottom and injects it into the well through the mud discharge pipe 9.
[0028] The height of the mobile submersible pump 3 can also be lowered as needed, and the first control valve 10 on the first pipe 6 and the second pipe 7 can be opened at the same time. The mobile submersible pump 3 will draw mud and water, part of which will enter the Y-type filter 8 and part of which will be injected into the well through the mud discharge pipe 9. If bottom stirring is no longer required, the mobile submersible pump 3 can also be lowered to the bottom of the brine tank 13, the first pipe 6 can be closed, the second pipe 7 can be opened, and the mud can be discharged through the mobile submersible pump 3.
[0029] Example 2
[0030] This embodiment is basically the same as Embodiment 1, except that: Figure 4 As shown, the drain port of the Y-type filter 8 is connected to a drain valve 11, which is connected to the sludge discharge pipe 9 via a drain pipe 12. A second control valve 20 is installed on the third pipe 21, which can be an electric valve or a manual valve, etc.
[0031] As needed, the drain valve 11 can be opened periodically and the second control valve 20 closed, and the brine or mud water drawn by the submersible pump 3 can be used to directly send the intercepted salt mud to the mud discharge pipe 9.
[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
