Description

Technical Field

[0001] The invention relates to the technical field of submersible pumps, and in particular to a mining anti-clogging submersible pump, which is particularly suitable for application in accident pools in the nonferrous metal industry. Background Art

[0002] Submersible pumps have been widely used to transport liquids due to their advantages such as small footprint, reliable use, and simple maintenance. At present, submersible pumps are generally designed to transport liquid media with strong fluidity. However, the conditions for transporting submersible pumps in accident pools in the non-ferrous metal industry are relatively complex and harsh. There are fine particles and slurry at the bottom of the accident pool and in the transported medium, which leads to frequent impeller jams and pipeline blockages in submersible pumps, resulting in high maintenance costs for submersible pumps and reduced service life of submersible pumps. In severe cases, it directly leads to shutdown of mineral processing production. At present, most submersible pump anti-clogging designs use a filter screen at the inlet. This design method can filter large debris to a certain extent, but it is not very effective in preventing blockages caused by fine particles and slurry.

[0003] In order to solve the above problems, Chinese patent CN 211314563 U discloses "a submersible pump with an anti-sedimentation function", and designs a submersible pump with an anti-sedimentation function. The invention device mainly includes a motor, a pump body, a liquid inlet pipe and a liquid outlet pipe. The pump body is provided with a liquid inlet and a liquid outlet, wherein the liquid outlet is connected to the liquid outlet pipe, and an independent turntable is provided at the bottom of the liquid inlet. The center of the turntable is fixedly connected to the impeller shaft in the pump body, and a plurality of fixed stirring rods are provided at the bottom of the turntable. When working, the turntable at the bottom of the liquid inlet rotates synchronously with the impeller shaft. When the turntable rotates, the stirring rod fixed at the bottom of the turntable rotates, so that the sediment at the bottom of the container is constantly turned over and dissolved in the liquid medium, which can effectively prevent the continued generation of sediment and avoid the failure caused by the submersible pump directly sucking in a large amount of sediment. There is no need to frequently clean due to excessive sediment accumulated at the bottom of the container, but the stirring rod rotates to stir the sediment, which has the problems of large energy consumption and affecting the motor power output of the submersible pump; Chinese patent CN214118506 U discloses "a modular submersible pump", which mainly includes a pump body, a water outlet module, a plurality of shaft tube modules and a motor, wherein the plurality of shaft tube modules are mainly composed of a submersible transmission shaft and a connecting pipe set, and the submersible transmission shaft and the connecting pipe of different lengths form a complete shaft tube. By selecting and matching shaft tubes of different lengths, the modular submersible pump can be used at different submersible depths, which can meet the use requirements at different submersible depths, reduce the manufacturing difficulty and use cost, and have high versatility. However, since the stirring shaft and the stirring wheel are installed at the bottom of the submersible pump, when the submersible pump is in working state, the stirring wheel rotates and rubs against the slurry accumulated at the bottom, which will cause wear to the stirring wheel, and there are still shortcomings such as the need to replace the stirring wheel regularly; Chinese patent CN 207437387 U also disclosed "a submersible pump". The inventive device mainly includes a submersible pump body, a motor and a stirring member. The stirring member is arranged at the bottom of the submersible pump body. The stirring member arranged at the bottom of the submersible pump body can be used to stir the body regularly or in real time to prevent debris, soil or other debris from accumulating at the bottom of the submersible pump body. However, since the stirring member is installed at the bottom of the submersible pump, when the submersible pump is in working state, the stirring member rotates and rubs against the slurry accumulated at the bottom, which will cause wear to the stirring member. There are also shortcomings such as the need to regularly replace the stirring wheel.

[0004] Therefore, it is of practical significance to develop an anti-clogging submersible pump for mining. Utility Model Content

[0005] The task of the present invention is to overcome the deficiencies of the prior art and provide a mining anti-clogging submersible pump, which can not only speed up the submersible pump to transport the medium, but also add liquid to the pool body, effectively prevent the concentration of sediment and reduce the probability of impeller jamming and conveying pipeline blockage accidents, increase the service life of the submersible pump, and reduce the labor intensity of maintenance personnel, thereby ensuring the stable operation of the submersible pump.

[0006] The task of the present invention is accomplished by the following technical solutions:

[0007] The anti-clogging submersible pump for mining comprises a power motor, an anti-clogging flushing water pipe, a lower filter, a pump body impeller, an upper filter, a bearing body and a transmission wheel as a pump body; the head end of the bearing body is connected to the power motor and the transmission wheel, and the bottom section is provided with an upper filter that can filter floating objects on the liquid surface of the pool body, a pump body impeller and a lower filter at the bottom end that can filter deposited debris on the bottom of the pool; at least three anti-clogging flushing water pipes are evenly distributed on the inner peripheral wall of the pump body, and the pipe head of the anti-clogging flushing water pipe is along the rotating tangential direction of the pump body impeller, and the medium in the pool body is stirred with flushing water to make slurry, which can effectively reduce the concentration of the medium transported by the pool body and clean the debris blocked by the lower filter.

[0008] Compared with the prior art, the present invention has the following advantages or effects:

[0009] (1) Because three anti-blocking flushing water pipes are installed from the upper part of the pump body to the lower filter screen of the inlet, and the flushing water pipes are along the rotating tangent direction of the pump body impeller, when the flushing water is turned on, the medium inside the pool body is stirred to achieve slurrying, so it can effectively reduce the concentration of the pool body conveying medium and clean the lower filter screen clogging debris, preventing the impeller of the submersible pump from getting stuck and the conveying pipeline from getting blocked during the conveying process due to the large particle size and viscosity of the medium deposited at the bottom of the accident pool.

[0010] (2) At the same time, due to the use of two-stage filtration, the upper filter is set at the outer shell of the bearing body to filter the floating objects on the liquid surface of the pool; the lower filter is set at the bottom impeller inlet to filter the sediment at the bottom of the pool, so it can more effectively ensure the debris filtering ability of the submersible pump and prevent the occurrence of blockage accidents.

[0011] (3) In addition, due to the modularization of each component, the submersible pump has a simple structure, is easy to install and disassemble, and has low maintenance cost and time.

[0012] In short, the utility model has a simple structure, is easy to disassemble, and can ensure the ability to filter debris and reduce the probability of clogging accidents. BRIEF DESCRIPTION OF THE DRAWINGS
