Description

Technical Field

[0001] This utility model relates to the field of mining auxiliary machinery technology, specifically a sand pump heat dissipation water recovery device. Background Technology

[0002] Sand pumps are critical equipment in mining production. During the transport of high-concentration, highly abrasive slurries, they generate significant heat due to mechanical friction and fluid shear. To ensure the long-term stable operation of key components such as bearings and seals, an effective cooling system is necessary. Currently, the most common method is water cooling, which involves directly flushing or passing clean water through a cooling water jacket to lower the sand pump's temperature.

[0003] The mining production environment is harsh. After use, the cooling water for sand pumps, although its main change is an increase in temperature, often carries small amounts of potentially harmful fine solid particles, such as mineral powder and silt. Currently, most mining companies treat this cooling water in a rather crude way, usually discharging it directly into tailings ponds or onto the surface. This method has two major drawbacks: first, it causes a serious waste of water resources, especially in water-scarce mining areas, greatly increasing production and operating costs; second, it increases the load on the mining area's water treatment system, contradicting the development concepts of green mining and energy conservation and environmental protection. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a sand pump cooling water recycling device, which transforms sand pump cooling water from wastewater into a recyclable resource, significantly reducing the consumption of fresh water and the amount of sewage discharge, directly reducing the water cost and sewage treatment cost of enterprises, while actively responding to the national call for energy conservation and emission reduction, with outstanding economic and environmental benefits, and can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sand pump cooling water recovery device, comprising an outlet pipe connected to the sand pump cooling water outlet and a return pipe connected to the sand pump cooling water inlet or water tank. A serpentine pipe is provided between the outlet pipe and the return pipe. The serpentine pipe includes several horizontal pipes and bends. A rotatable baffle is provided in the middle of the inner surface of the horizontal pipe. When the baffle is rotated to a state perpendicular to the horizontal pipe, it blocks the position below the middle of the horizontal pipe. A downward-facing sewage pipe is provided between the horizontal pipe at the end of the serpentine pipe and the return pipe. A sewage valve is provided on the sewage pipe, and a return valve is provided on the return pipe.

[0006] As a preferred embodiment of this utility model, the baffle is semi-circular, and the baffle is fixedly connected to the semi-circular filter screen.

[0007] As a preferred technical solution of this utility model, the inner surface of the horizontal tube of the serpentine tube is rotatably provided with a rotating shaft, the rotating shaft is fixedly connected to the baffle, and the end of the rotating shaft passes through the outer surface of the horizontal tube and is connected to a pinion, the pinion meshes with the rack, and the rack is connected to the drive mechanism.

[0008] As a preferred technical solution of this utility model, the driving mechanism includes a driving motor and a driving screw mounted on a mounting frame. The mounting frame is fixedly mounted on the outside of the serpentine tube. The driving motor is mounted on the upper surface of the top plate of the mounting frame. The output shaft of the driving motor passes through the lower surface of the top plate of the mounting frame and is connected to the driving screw through a coupling. The driving screw is threadedly connected to a screw hole on the rack.

[0009] As a preferred embodiment of this utility model, a protective shell is provided on the outside of the mounting bracket, and the rack is slidably disposed in a groove opened inside the protective shell.

[0010] As a preferred technical solution of this utility model, the inner surface of the horizontal tube of the serpentine tube is rotatably provided with a rotating shaft, the rotating shaft is fixedly connected to the baffle, and the end of the rotating shaft passes through the outer surface of the horizontal tube and is connected to the large gear. The upper and lower adjacent large gears mesh with each other, and one of the rotating shafts is connected to the output shaft of the external reduction motor through a coupling.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. By transforming the water used for cooling sand pumps from wastewater into a recyclable resource, the consumption of fresh water and the amount of sewage discharged are significantly reduced, directly lowering the water costs and sewage treatment fees for enterprises. At the same time, it actively responds to the national call for energy conservation and emission reduction, and has outstanding economic and environmental benefits.

[0012] 2. The serpentine pipe extends the path of the cooling water, thereby effectively cooling it and improving the heat dissipation effect after recovery. At the same time, the horizontal section of the serpentine pipe provides a suitable installation and working environment for the filtration device, allowing it to filter and purify the cooling water while simultaneously cooling it.

[0013] 3. A rotatable baffle is used to filter impurities in the cooling water. When the baffle is vertical, it effectively traps solid impurities in the water and temporarily stores them in the lower space of the horizontal pipe, preventing damage to the sand pump components. When the baffle is horizontal, the water flow itself can be used to flush away the trapped impurities, preventing particles from accumulating and clogging the recycling system, thus avoiding impact on return water efficiency.

[0014] 4. By simply operating the return water valve, the drain valve, and the rotating baffle, the wastewater cleaning operation of the recovery unit can be completed quickly. The entire process requires no disassembly of any parts and no interruption of the main cooling system of the sand pump, greatly reducing maintenance and time costs and meeting the needs of continuous mining production.

[0017] 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.

[0018] Please see Figure 1-3 This utility model provides a technical solution: a sand pump cooling water recovery device, comprising an outlet pipe 1 connected to the sand pump cooling water outlet and a return pipe 2 connected to the sand pump cooling water inlet or water tank. A serpentine pipe 3 is provided between the outlet pipe 1 and the return pipe 2. The sand pump cooling water is discharged into the serpentine pipe 3 through the outlet pipe 1, and then returns to the cooling system or water tank through the return pipe 2. The serpentine pipe 3 can extend the path of the cooling water, thereby effectively cooling it and improving the cooling effect after recovery. Heat sinks can also be installed on the outside of the serpentine pipe 3 to further improve the cooling efficiency of the cooling water.

[0019] The serpentine pipe 3 includes several horizontal pipes and bends. A rotatable baffle 8 is installed in the middle of the inner surface of each horizontal pipe. When the baffle 8 is rotated to a position perpendicular to the horizontal pipe, it blocks the area below the middle of the horizontal pipe. When the cooling water passes through the inside of the serpentine pipe 3, the vertical baffle 8 blocks impurities in the water at the lower front, reducing impurities in the recycled water, improving the quality of the recycled water, and preventing damage to the sand pump components when the recycled water is reused for sand pump cooling. After a period of operation, the baffle 8 can be rotated to a position horizontal to the horizontal pipe, allowing the cooling water to directly flush the impurities at the lower front of the baffle 8 to the outside, preventing impurity particles from accumulating and clogging the recycling system, thus affecting the return water efficiency.

[0020] A drain pipe 4 facing downwards is installed between the horizontal pipe at the end of the serpentine pipe 3 and the return water pipe 2. A drain valve 6 is installed on the drain pipe 4, and a return water valve 5 is installed on the return water pipe 2. When recycling heat dissipation water, the baffle 8 is rotated to a position perpendicular to the horizontal pipe, the return water valve 5 is opened, and the drain valve 6 is closed. The heat dissipation water passes through the baffle 8 to filter impurities and then enters the heat dissipation system or water tank through the return water pipe 2 for reuse. When flushing impurities, the baffle 8 is rotated to a position parallel to the horizontal pipe, the return water valve 5 is closed, and the drain valve 6 is opened. The heat dissipation water passes through the serpentine pipe 3 to flush impurities, and then the heat dissipation water containing impurities is discharged through the drain valve 4.

[0021] Both the return water valve 5 and the drain valve 6 are electrically connected to an external control switch and are powered by an external power source.

[0022] In the preferred embodiment, the baffle 8 is semi-circular, and the baffle 8 is fixedly connected to the semi-circular filter screen 9. That is, the upper part of the baffle 8 is set as the filter screen 9. The baffle 8 and the filter screen 9 rotate around their connection point as an axis, which realizes efficient filtration and impurity interception of water flow in a vertical state, and achieves completely unobstructed and self-cleaning sewage discharge without dead corners in a horizontal state, thus taking into account both filtration efficiency and anti-clogging reliability.

[0023] In the preferred embodiment, a rotating shaft 7 is rotatably mounted on the inner surface of the horizontal tube of the serpentine tube 3. The rotating shaft 7 is fixedly connected to the baffle 8, and the end of the rotating shaft 7 extends out of the outer surface of the horizontal tube and is connected to the pinion 10. The pinion 10 meshes with the rack 11, and the rack 11 is connected to the drive mechanism. The drive mechanism drives the rack 11 to move up and down, and the rack 11 drives all the pinions 10, the rotating shaft 7, and the baffle 8 to rotate. This enables the synchronous adjustment of multiple baffles 8, allowing the simultaneous control of the opening and closing of multiple filter units with a single drive source. This ensures a high degree of consistency in the actions of each baffle 8 and filter screen 9, improves sewage discharge efficiency, and simplifies the overall structure and control process.

[0024] A further preferred technical solution is that the driving mechanism includes a drive motor 13 and a drive screw 14 mounted on a mounting frame 12. The mounting frame 12 is fixedly mounted on the outside of the serpentine tube 3. The drive motor 13 is mounted on the upper surface of the top plate of the mounting frame 12. The output shaft of the drive motor 13 passes through the lower surface of the top plate of the mounting frame 12 and is connected to the drive screw 14 via a coupling. The drive screw 14 is threadedly connected to a screw hole on the rack 11. The drive motor 13 drives the drive screw 14 to rotate, which in turn drives the rack 11 to move up and down, thereby controlling the rotation of multiple pinions 10, the rotating shaft 7, and the baffle 8. The control process is simple and easy to operate. The drive motor 13 is electrically connected to an external control switch and is powered by an external power supply. The drive motor 13 can be a commonly used servo motor. By presetting the corresponding rotation speed through a servo controller, the baffle 8 can quickly switch between vertical and horizontal states.

[0025] Furthermore, a protective shell 15 is provided on the outer side of the mounting bracket 12 to provide sealing protection for components such as the rack 11, pinion 10, and rotating shaft 7, making the device suitable for harsh environments with high dust and high wear in mining sites and reducing the device failure rate. The rack 11 is slidably disposed in a groove (not shown in the figure) opened inside the protective shell 15. The groove is used to limit the rack 11, allowing it to slide up and down under the rotation of the drive screw 14.

[0026] Please see Figure 4 This utility model also provides another embodiment, which is largely the same as the aforementioned embodiment, except that: a rotating shaft 7 is rotatably mounted on the inner surface of the horizontal tube of the serpentine tube 3. The rotating shaft 7 is fixedly connected to the baffle 8, and the end of the rotating shaft 7 extends through the outer surface of the horizontal tube and is connected to the large gear 16. The upper and lower adjacent large gears 16 mesh with each other. One of the rotating shafts 7 is connected to the output shaft of the external geared motor through a coupling. The external geared motor is electrically connected to an external control switch and is powered by an external power supply. Furthermore, the external geared motor can be a commonly used servo motor, and the corresponding rotation speed can be preset by the servo controller, enabling the baffle 8 to quickly switch between vertical and horizontal states.

[0027] An external geared motor drives one of the rotating shafts 7 to rotate, which in turn drives all the rotating shafts 7 and baffles 8 to rotate synchronously via the corresponding large gear 16, adjusting the angle of the baffles 8. In this embodiment, when rinsing impurities, all the baffles 8 can rotate downstream of the heat dissipation water, i.e., away from the impurity accumulation point, allowing the impurities to be discharged more quickly through the drain pipe 4.

[0028] The drive motor 13, external geared motor, return water valve 5, and drain valve 6 used in this application are all commonly used electronic components in the prior art. Their specific structures, working principles, control methods, and circuit connections are all known technologies and will not be described in detail here.

[0029] Optionally, a protective shell is also provided on the outside of the serpentine tube 3 where the large gear 16 is located, for sealing and dust prevention, reducing wear between the large gears 16, and extending the service life of the device.

[0030] The parts not disclosed in this utility model are all prior art, and their specific structures, materials, and working principles will not be described in detail. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
