Technical Field

[0001] The utility model relates to the technical field of rare earth production, in particular to an anti-clogging water pump for discharging liquid from a rare earth production drying yard. Background Art

[0002] The rare earth production drying yard is mainly used for the natural evaporation and concentrated crystallization of rare earth materials, and is an important step in rare earth purification. By drying or drying, moisture and other impurities in rare earth materials can be removed, improving their purity and quality. However, during the rare earth natural crystallization production process, the rare earth liquid stored in the liquid reservoir needs to be replenished to the evaporation tank in stages according to actual production conditions. Since the rare earth liquid contains high concentrations of rare earth cations and Cl - When the temperature is low or the evaporation volume is too large, these ions may form crystals, thereby blocking the water pump pipeline and preventing the liquid from being discharged in time. Utility Model Content

[0003] In view of the above-mentioned defects, the present invention provides an anti-clogging water pump for discharging liquid from a rare earth production drying yard, which can fully filter out particles in the liquid when the rare earth liquid crystallizes.

DETAILED DESCRIPTION

[0020] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific examples described herein are merely illustrative of the present invention and are not intended to limit the present invention. Directional terms such as up, down, left, right, front, or back, mentioned in the following embodiments, are merely references to the directions in the accompanying drawings. Therefore, the directional terms used are intended to illustrate and not to limit the present invention. Furthermore, throughout the embodiments, the same reference numerals represent the same elements.

[0021] like Figures 1 to 4 The present invention discloses an anti-clogging water pump for discharging liquid from a rare earth production drying yard, comprising an L-shaped inlet pipe 1. The bottom of the vertical end of the inlet pipe 1 is connected to the pump of the liquid storage tank, and the end of the horizontal section of the inlet pipe 1 is provided with an external thread.

[0022] The liquid inlet pipe 1 is connected to the slow-flow pipe 2, and the slow-flow pipe 2 includes three sections of pipelines. One end of the slow-flow pipe 2 is the liquid inlet pipe connecting pipeline 20, which is a circular pipeline with an internal thread at the end. The liquid inlet pipe connecting pipeline 20 is fixedly connected with the external thread at the horizontal end of the liquid inlet pipe 1 through the internal thread. The liquid inlet pipe connecting pipeline 20 is connected to the slow-flow pipeline 21 in the middle section of the slow-flow pipe 2. The slow-flow pipeline 21 is a square tube, and a number of baffles 23 are provided on the upper and lower sides of the slow-flow pipeline 21. The baffles 23 are inclined toward one side of the liquid inlet connecting pipeline, and there is a gap between adjacent baffles 23 on the same side, and the baffles 23 on the opposite side are staggered. The corners and joints of the baffles 23 are chamfered.

[0023] A diverter plate 24 is installed between two adjacent baffles 23 on the same side. The ends of the diverter plate 24 are fixedly connected to the inner walls of the slow-flow pipe 21. The cross-section of the diverter plate 24 is a parallelogram, and the corners of the diverter plate 24 are also rounded. The inner edge of the diverter plate 24 protrudes beyond the inner edge of the baffle plate 23, leaving a certain gap between the diverter plate 24, the baffle plate 23, and the inner wall of the slow-flow pipe 21.

[0024] The slow flow pipeline 21 is connected to the filter connecting pipeline 22 at a side away from the liquid inlet connecting pipeline 20. The filter connecting pipeline 22 is a circular pipeline with an external thread at the end.

[0025] As a further illustration of this example, when the slurry reaches the middle of the slow-flow tube 2, it will be blocked by the baffle 23 and the diverter plate 24. Part of the liquid enters between the baffle 23 and the diverter plate 24, generating a diversion of the slurry. The slurry diversion goes around the diverter plate 24 and merges with the mainstream again. Since the diverter plate 24 is a parallelogram, when the diversion merges into the mainstream, the movement direction of the diversion will be opposite to the movement direction of the mainstream, thereby slowing down the flow rate of the slurry.

[0026] The slow-flow tube 2 is fixedly connected to the liquid inlet of the filter 3 via the external threads at the end of the filter connection pipe 22. The liquid outlet of the filter 3 is connected to the fluid delivery pipe 4. The fluid delivery pipe 4 is a circular pipe with a liquid inlet and a liquid outlet at each end. The liquid inlet of the fluid delivery pipe 4 is fixedly connected to the filter 3. The middle portion of the fluid delivery pipe 4 first contracts from the liquid inlet to the liquid outlet, and then expands. The length of the pipe in the contraction section is shorter than the length of the pipe at the expansion end.

[0027] As a further illustration of this example, when the feed liquid flows through the fluid delivery tube 4, the diameter of the fluid delivery tube 4 shrinks first, which will accelerate the flow rate of the filtered feed liquid. At the same time, the diameter of the fluid delivery tube 4 shrinks and then expands, ensuring the flow rate.

[0028] The liquid outlet of fluid delivery pipe 4 is connected to the liquid inlet of valve 5, and the liquid outlet of valve 5 is connected to one end of liquid outlet connecting pipe 6. The other end of liquid outlet connecting pipe 6 is provided with a connecting flange. Liquid outlet connecting pipe 6 mates with the connecting flange of liquid outlet pipe 7 through the connecting flange. Liquid outlet connecting pipe 6 and liquid outlet pipe 7 are fixedly connected by bolts and nuts at the flanges. The end of liquid outlet pipe 7 bends downward and connects to the evaporation tank.

[0029] The working principle and use process of this utility model:

[0030] When the liquid needs to be injected into the evaporation tank 8, the valve 5 is opened and the pump in the liquid storage tank is started. The pump sucks the liquid in the liquid storage tank into the liquid inlet pipe 1 and transports it along the pipeline. The liquid is transported to the slow-flow pipe 2, where the flow rate decreases. The liquid is transported from the slow-flow pipe 2 to the filter 3. The liquid with a slower flow rate can pass through the filter 3, fully filtering the crystals produced by low temperature to prevent clogging at the valve 5 and causing damage to the valve 5. The filtered liquid is discharged from the filter 3 and accelerated through the fluid conveying pipe 4 to ensure the conveying flow rate. The liquid then enters the valve 5, and then enters the liquid outlet pipe 7 through the liquid outlet connecting pipe 6, and is finally discharged from the liquid outlet pipe 7 to the evaporation tank 8.

[0031] The above are only preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above-mentioned implementation measures. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
