[0002] When the copper industry company production workshop carries out ore dressing and smelting to copper ore, needs to use the mill to carry out the crushing to the ore material, and the mill needs to rotate under the drive of the motor to carry out the grinding operation. A large amount of heat is generated when the motor is running, and if heat is not dissipated in time, the motor temperature will rise sharply, causing a series of problems, such as insulation material aging, reducing insulation performance, increasing the risk of electric leakage and short circuit; accelerate the oxidation of the lubricating oil inside the motor, reduce the lubrication effect, and aggravate the wear; the thermal expansion of the materials inside the motor, affecting the matching precision between parts, leading to mechanical failure.

[0003] The existing motor cooling is mainly through water cooling, that is, setting cooling pipeline on the motor, and through the circulation of cooling water to absorb and take away heat, but the cooling water contains alkaline ingredients, soil, algae and other solid impurities, which will cause calcification and scaling of the cooling pipeline inside the motor after long-term use, reduce water flow, reduce heat exchange effect, affect heat dissipation efficiency, cause the motor temperature to rise too high, and even cause the mill to trip, affecting production.

[0034] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0035] like Figure 1 As shown, the cooling water filtration equipment includes a tank 1, a filtration device 2, a cleaning device 3, and a power unit 4. The top of the tank 1 is provided with a top plate 11, and the bottom is provided with a bottom plate 12. The upper part of the side wall of the tank 1 is provided with a water inlet 13, the lower part of the side wall is provided with a water outlet 14, and the bottom plate 12 is provided with a drain outlet 15.

[0036] A support 5 is provided at the bottom of the tank 1, and the support 5 is composed of multiple support legs 51. The support 5 can support the tank 1 and keep the tank 1 stable.

[0037] A three-way valve 141 is installed on the outlet 14, which is connected to the flushing pipe 35 and the outlet pipe 16. By connecting the flushing pipe 35 and the outlet pipe 16 to the outlet 14 via the three-way valve 141, when the filter membrane tube 22 is clogged, high-pressure flushing water is delivered into the filter tube 221 through the flushing pipe 35 to flush the filter membrane tube 22, remove impurities from the filter membrane 222, and restore the filter membrane tube 22's filtration capacity.

[0038] The base plate 12 is inverted conical, and the drain outlet 15 is located at the tip of the base plate 12. By making the base plate 12 inverted conical and setting the drain outlet 15 at the tip of the base plate 12, impurities on the base plate 12 can be collected towards the drain outlet 15 for easy discharge, preventing impurities from accumulating on the base plate 12 and clogging the drain outlet 15.

[0039] A water inlet valve 131 is installed on the water inlet 13, and a drain valve 151 is installed on the drain outlet 15. Impurities that have settled and accumulated on the bottom plate 12 can be discharged periodically through the drain valve 151.

[0040] like Figure 2As shown, the tank body 1 is internally provided with a partition plate 17, a support plate 18 and a settling cylinder 19.

[0041] The partition plate 17 is a circular plate, has the same inner diameter as the tank body 1, is horizontally arranged in the tank body 1, is located below the water inlet 13, and the side edge of the partition plate 17 is fixedly connected with the inner side wall of the tank body 1. A power cavity 1a is formed at the upper portion of the partition plate 17.

[0042] The support plate 18 is a circular plate, has a smaller diameter than the inner diameter of the tank body 1, is horizontally arranged in the tank body 1, is located above the water outlet 14, and is fixedly connected with the inner wall of the tank body 1 through four support rods 181. The axis of the support plate 18 is collinear with the axis of the tank body 1.

[0043] A filtering cavity 1b is formed between the partition plate 17 and the support plate 18 in the tank body 1, and a settling cavity 1c is formed below the support plate 18.

[0044] As shown in Figure 2 , Figure 3 and Figure 4 , the filtering device 2 comprises a filtrate bin 21 and a filtering membrane tube 22. The filtrate bin 21 is a funnel-shaped plate, has the same diameter as the support plate 18 at the upper end opening, is fixedly connected with the support plate 18 at the upper end opening, and is in communication with the water outlet 14 at the lower end opening. The filtrate bin 21 collects the cooling water filtered by the filtering membrane tube 22 and then delivers the cooling water to the water outlet 14 for discharge.

[0045] The filtering membrane tube 22 comprises a filtering tube 221 and a filtering membrane 222 arranged on the filtering tube 221. The filtering tube 221 is vertically arranged in the filtering cavity 1b, has a closed upper end and an open lower end, has a plurality of through holes uniformly arranged on the side wall, is rotatably connected with the partition plate 17 and the support plate 18 at the upper and lower ends respectively, and extends into the filtrate bin 21 through the support plate 18 at the lower end.

[0046] The filtering membrane 222 is sleeved on the filtering tube 221. The cooling water filtered by the filtering membrane 222 enters the filtering tube 221 through the through holes on the filtering tube 221, and then enters the filtrate bin 21 and is discharged through the water outlet 14. The filtering membrane tube 22 is a prior art and can be purchased or ordered, which will not be described here.

[0047] The two ends of the filtering tube 221 are rotatably connected with the partition plate 17 and the support plate 18 respectively. The cooling water is filtered by the filtering membrane tube 22, so that the alkaline components and solid impurities in the cooling water can be filtered out, thereby preventing the calcification and fouling of the cooling pipeline.

[0048] The cleaning device 3 comprises a flow guide pipe 31 and an ultrasonic generator 34. The flow guide pipe 31 is vertically arranged in the filter cavity 1b and located outside the filter membrane pipe 22. The upper end of the flow guide pipe 31 is fixedly connected with the partition plate 17, the end thereof extends to above the partition plate 17 through the partition plate 17, and the lower end thereof extends to near the support plate 18. The side of the flow guide pipe 31 facing the filter membrane pipe 22 is provided with a brush 32 and a plurality of water outlets 33. The end of the brush 32 abuts against the filter membrane pipe 22, so that the filter membrane pipe 22 can be scraped by the brush 32 when the filter membrane pipe 22 rotates.

[0049] The flow guide pipe 31 is located outside the filter membrane pipe 22, which means the side of the filter membrane pipe 22 close to the inner wall of the tank 1.

[0050] The power device 4 is arranged on the tank 1 and used to drive the filter membrane pipe 22 to rotate. The structure of the power device 4 will be described in detail below.

[0051] The water adhered to the filter membrane pipe 22 can be washed away by spraying water on the filter membrane pipe 22 through the water outlets 33 of the flow guide pipe 31. The brush 32 is arranged on the side of the flow guide pipe 31 facing the filter membrane pipe 22. When the filter membrane pipe 22 is driven to rotate by the power device 4, the filter membrane pipe 22 can be scraped by the brush 32 of the flow guide pipe 31, so that the impurities adhered to the filter membrane 222 can be cleaned, and the filter membrane 222 of the filter membrane pipe 22 can be prevented from being blocked.

[0052] The ultrasonic generator 34 is arranged in the filter cavity 1b, and the emission port of the ultrasonic generator 34 faces the filter membrane pipe 22. The number of the ultrasonic generators 34 is the same as that of the filter membrane pipes 22, and the ultrasonic generators 34 are arranged one by one corresponding to the filter membrane pipes 22.

[0053] The filter membrane pipe 22 can be vibrated by emitting ultrasonic waves on the filter membrane pipe 22 through the ultrasonic generator 34, so that the impurities can be prevented from gathering on the filter membrane pipe 22, and the impurities adhered to the filter membrane pipe 22 can be caused to fall off, thereby preventing the filter membrane pipe 22 from being blocked and improving the filtering efficiency.

[0054] The settling cylinder 19 is a circular truncated cone cylinder with both ends open. The settling cylinder 19 is fixedly arranged in the settling cavity 1c and located below the filtrate bin 21. A plurality of settling cylinders 19 are arranged. The plurality of settling cylinders 19 have different diameters and are sleeved together with the same axis (see Figure 7 ).

[0055] The settling cylinder 19 is arranged in the settling cavity 1c. The settling cylinder 19 is a circular truncated cone cylinder, which can block the flow of the washing water in the settling cavity 1c, promote the impurities to quickly settle on the bottom plate 12, and block the impurities in the settling cavity 1c from floating to the filter cavity 1b, thereby reducing the impurities in the pure water in the filter cavity 1b, improving the filtering efficiency of the filter membrane pipe, and reducing the possibility of the filter membrane pipe 22 being blocked.

[0056] As shown in Figure 2 and Figure 5 , the power device 4 comprises a rotating shaft 41, a rotating impeller 42 and a connecting rod 43.

[0057] The rotating shaft 41 is vertically arranged, the upper end is rotationally connected with the top plate 11, and the lower end extends into the filtering cavity 1b through the partition plate 17.

[0058] The rotating impeller 42 is arranged in the power cavity 1a and fixedly connected with the rotating shaft 41.

[0059] The connecting rod 43 is arranged in the filtering cavity 1b, one end of which is fixedly connected with the rotating shaft 41, and the other end extends along the radial direction of the rotating shaft 41, and the end portion is provided with a sector gear 44 which is horizontally arranged and fixedly connected with the connecting rod 43.

[0060] The filtering membrane tube 22 is provided with a driven gear 23 matched with the sector gear 44, which is fixedly arranged on the filtering membrane tube 22 and corresponds to the position of the sector gear 44, and the axis of the driven gear 23 is collinear with the axis of the filtering membrane tube 22.

[0061] The filtering membrane tube 22 is provided with a driven gear 23 matched with the sector gear 44, which means that when the connecting rod 43 rotates towards the filtering membrane tube 22, the sector gear 44 and the driven gear 23 are engaged to drive the filtering membrane tube 22 to rotate, and when the connecting rod 43 rotates away from the filtering membrane tube 22, the sector gear 44 and the driven gear 23 are disengaged.

[0062] Therefore, when the cooling water flowing into the power cavity 1a from the water inlet 13 drives the rotating shaft 41 to rotate, the sector gear 44 and the driven gear 23 are engaged when the connecting rod 43 rotates towards the filtering membrane tube 22, driving the filtering membrane tube 22 to rotate, and the power device 4 has a simple structure and does not need to consume electric energy.

[0063] The axis of the water inlet 13 is perpendicular to the stirring shaft and not coplanar. By arranging the axis of the water inlet 13 to be perpendicular to the stirring shaft and not coplanar, the direction of the water flow of the cooling water entering from the water inlet 13 is towards the rotating impeller 42, which can provide stronger power to the rotating impeller 42 to accelerate the rotation of the rotating impeller 42, thereby driving the filtering membrane tube 22 to rotate quickly through the sector gear 44, and improving the cleaning efficiency of the impurities on the filtering membrane tube 22 by the brush 32.

[0064] As shown in Figure 6 , four filtering membrane tubes 22 are arranged, which are uniformly distributed in a circle, and the number of the four guide tubes 31 is the same as that of the four filtering membrane tubes 22, and the four guide tubes 31 are arranged one by one corresponding to the four filtering membrane tubes 22.

[0065] The four guide pipes 31 are arranged in a one-to-one correspondence with the four filter membrane tubes 22, meaning that the four guide pipes 31 are respectively arranged on the side of the four filter membrane tubes 22 that are close to the inner wall of the tank body 1.

[0066] By setting four filter membrane tubes 22, the filtration capacity and filtration efficiency of the equipment can be improved.

[0067] When this utility model is in use, cooling water enters the power chamber 1a through the water inlet 13. When the cooling water flows, it drives the rotating shaft 41 to rotate. When the connecting rod 43 rotates to face the filter membrane tube 22, the sector gear 44 and the driven gear 23 mesh, driving the filter membrane tube 22 to rotate. The brush 32 on the guide pipe 31 brushes the filter membrane tube 22 to clean the impurities adhering to the filter membrane tube 22.

[0068] Cooling water in the power chamber 1a is diverted to each guide pipe 31. Some large particles of impurities in the cooling water settle directly into the settling chamber 1c within the guide pipe 31. The remaining impurities, along with the cooling water, pass through the outlet 14 on the guide pipe 31 and enter the filter chamber 1b. In the filter chamber 1b, the cooling water passes through the filter membrane 222 of the filter membrane tube 22 and enters the filter tube 221, and is then transported through the filtrate chamber 21 to the outlet 14 for discharge. Impurities filtered by the filter membrane tube 22 in the cooling water enter the settling chamber 1c. Under the action of the settling cylinder 19, the impurities in the settling chamber 1c quickly settle onto the bottom plate 12 and are periodically discharged through the drain outlet 15.

[0069] The ultrasonic generator 34 is turned on periodically to vibrate the filter membrane tube 22, preventing impurities from accumulating on it and causing any adhering impurities to fall off. When the filter membrane 222 becomes clogged, the cooling water in the tank 1 is drained, and the outlet 14 is disconnected from the outlet pipe 16 via the three-way valve 141, connecting the outlet 14 to the flushing pipe 35. High-pressure flushing water is then supplied to the filter membrane tube 22 through the flushing pipe 35 to flush it, removing impurities and restoring its filtration capacity.

[0070] Variations: such as Figure 7 As shown, this modified example differs from the above embodiment in that a rotating motor replaces the rotating impeller. The rotating motor is fixedly mounted on the top plate 11, and the upper end of the rotating shaft 41 passes through the top plate 11 and is fixedly connected to the rotating shaft of the rotating motor. The rotating motor drives the rotating shaft 41 to rotate. The rest of the structure is the same as the aforementioned embodiment, and will not be described again here.

[0071] The utility model discloses a filter membrane pipe 22 is set up in the jar body 1 to filter cooling water, can filter the alkaline component and solid impurity in cooling water, prevent the calcification of cooling pipeline and scale. The ultrasonic generator 34 is set up to the filter membrane pipe 22 and sends ultrasonic wave, makes the filter membrane pipe 22 vibrate, prevents the impurity from gathering on the filter membrane pipe 22, simultaneously makes the impurity that adheres on the filter membrane pipe 22 fall off, thereby plays the role of preventing the filter membrane pipe 22 from blocking, improves the filtering efficiency.

[0072] The water is spouted to the filter membrane pipe 22 through the water outlet hole 33 on the flow guide pipe 31, can wash off the part impurity that adheres on the filter membrane pipe 22, sets up the brush 32 on the side of the flow guide pipe 31 towards the filter membrane pipe 22, when the power device 4 drives the filter membrane pipe 22 to rotate, carries out the scraping to the filter membrane pipe 22 through the brush 32 on the flow guide pipe 31, cleans the impurity that adheres on the filter membrane 222, prevents the filter membrane 222 of filter membrane pipe 22 from blocking.
