Description

Technical Field

[0001] The utility model belongs to the technical field of salt lake brine processing, in particular to a salt lake brine filtering device. Background Art

[0002] In the processing of salt lake brine minerals, saturated magnesium chloride brine is an important raw material. The production process has high requirements for the turbidity of magnesium chloride brine. Unfiltered magnesium chloride brine often contains impurities such as colloids, iron and organic matter and cannot be used directly in the production process. Therefore, in order to ensure that the turbidity of magnesium chloride brine meets the requirements of the production process, a filtration device is required to effectively filter the magnesium chloride brine.

[0003] The existing salt lake brine filtration device filters the initial brine, removes suspended matter and a large amount of sediment on the surface of the brine, reduces the turbidity of the brine, and reduces the operating pressure of the subsequent process equipment. However, during the production process, as the seasonal temperature changes, the saturated magnesium chloride brine is prone to crystallization at low temperatures, which will condense on the surface of the filtration equipment, resulting in a decrease in the filtration performance of the filtration device.

[0004] Therefore, a salt lake brine filtering device is proposed. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0025] Reference Figures 1 to 5 As shown, this embodiment provides a salt lake brine filtering device, including: a sedimentation barrel 1, the top of the sedimentation barrel 1 is connected to a water inlet pipe 2, the bottom of the sedimentation barrel 1 is connected to a sewage pipe 3, and a sewage valve 4 is fixedly connected to the sewage pipe 3; the sedimentation barrel 1 is connected to a filter barrel 6 through a water diversion pipe 5, and a plurality of filter layers 7 are fixedly connected to the filter barrel 6; a water pump 8 is fixedly connected to the water diversion pipe 5, and the water pump 8 is fixedly connected to the top of the filter barrel 6, and a water outlet pipe 9 is fixedly connected to the water outlet end of the water diversion pipe 5, and the upper end of the water outlet pipe 9 is connected to a steam heating pipe 10, and the bottom end of the water outlet pipe 9 passes through the filter layer 7 and is located at the bottom of the sedimentation barrel 1; the top of the filter barrel 6 is connected to an overflow pipe 11.

[0026] Brine enters the sedimentation barrel 1 from the water inlet pipe 2, and is left to settle in the sedimentation barrel 1. Mud and other particles in the brine settle at the bottom of the sedimentation barrel 1, and are then discharged through the sewage pipe 3. The sewage is controlled by the sewage valve 4; the clear brine after the top sedimentation can enter the water outlet pipe 9 through the water diversion pipe 5 after starting the water pump 8, and then flow out from the bottom of the filter barrel 6 through the water outlet pipe 9. During this period, it mixes with the water vapor in the steam heating pipe 10 above the water outlet pipe 9. The brine is heated and diluted, which can avoid the crystallization of saturated salt in the brine, making the filtration process smoother and the filtration efficiency higher; after the brine enters the bottom of the filter barrel 6, it is filtered from bottom to top through multiple filter layers 7 to filter out suspended matter, organic matter and colloids in the brine. The brine filtered layer by layer finally overflows from the overflow pipe 11, which is convenient for subsequent processing.

[0027] According to a further optimized solution, a plurality of legs 12 are fixedly connected to the bottom of the sedimentation barrel 1 in a circumferential direction, and a support foot 13 is fixedly connected to the bottom of the legs 12 .

[0028] The legs 12 support the sedimentation barrel 1 to facilitate the discharge of sludge from the bottom sewage pipe 3, and the feet 13 increase the bottom area of ​​the legs 12 to make the legs 12 more stable.

[0029] According to a further optimization scheme, the water outlet angle between the water outlet pipe 9 and the steam heating pipe 10 is less than 90°.

[0030] The water flow angle between the water outlet pipe 9 and the steam heating pipe 10 is less than 90°, which can minimize the impact of the fluids in the two pipes and avoid fluid flow chaos.

[0031] According to a further optimization scheme, the particle sizes of filter materials used in the plurality of filter layers 7 are getting smaller and smaller from bottom to top.

[0032] Because the brine enters from the bottom of the filter barrel 6 and the water flows from bottom to top, the particle size of the filter material in the filter layer 7 becomes smaller and smaller from bottom to top. Optionally, coarse sand filter material, fine sand filter material and activated carbon filter material can be selected from bottom to top.

[0033] Furthermore, each filter layer 7 can be separated by gauze, and a support frame is fixedly connected to the outside of each filter layer.

[0034] To further optimize the solution, the outside of the filter barrel 6 is wrapped with a heat-insulating layer 14 .

[0035] The heat-insulating layer 14 can keep the brine in the filter barrel 6 warm, thereby preventing the brine from losing temperature too quickly during the filtration process, thereby preventing the brine from crystallizing during the filtration process, making the filtration process smoother and the filtration efficiency higher.

[0036] To further optimize the solution, a hydraulic telescopic rod 15 is fixedly connected to the top center of the sedimentation barrel 1. The telescopic end of the hydraulic telescopic rod 15 passes through the top of the sedimentation barrel 1 and is circumferentially fixedly connected to a plurality of connecting rods 16. The outer ends of the plurality of connecting rods 16 are commonly fixedly connected to a scraper ring 17. The outer wall of the scraper ring 17 abuts against the inner wall of the sedimentation barrel 1.

[0037] After the sediment in the brine is precipitated, the upper brine clear liquid is first led out through the water diversion pipe 5, and then the hydraulic telescopic rod 15 can be started to push the scraper ring 17 down to scrape the inner wall of the sedimentation barrel 1, so that the sludge attached to the inner wall of the sedimentation barrel 1 and the possible precipitated crystals are scraped off from the inner wall of the sedimentation barrel 1, and finally discharged from the bottom of the sedimentation barrel 1 through the sewage pipe 3.

[0038] According to a further optimized solution, the outer wall of the scraper ring 17 abuts against the inner wall of the sedimentation barrel 1, and the inner wall and the outer wall of the scraper ring 17 have a certain angle to form a tip.

[0039] The sharp corner formed at the bottom of the scraper ring 17 is conducive to scraping away the sludge attached to the inner wall of the sedimentation tank 1.

[0040] To further optimize the solution, a sedimentation ball 18 is fixedly connected to the water inlet of the water diversion pipe 5. The interior of the sedimentation ball 18 is hollow and connected to the water diversion pipe 5. An opening 19 is provided on the top of the sedimentation ball 18. A weight block 20 is fixedly connected to the bottom of the sedimentation ball 18 corresponding to the opening 19.

[0041] The density of the weight block 20 at the bottom of the sedimentation ball 18 is less than that of the sludge but greater than that of water. Therefore, the sedimentation ball 18 will sink to the surface of the sludge with the weight block 20 as the bottom. After the water pump 8 is turned on, the clear liquid enters the inner cavity of the sedimentation ball 18 from the opening 19 at the top of the sedimentation ball 18, and is then drawn away by the water diversion pipe 5. This can prevent the water diversion pipe 5 from drawing away the sludge when drawing the brine clear liquid. The water diversion pipe 5 is a hose. During the sinking process of the sedimentation ball 18, due to the gravity of the weight block 20, the opening 19 opposite to it is always facing upward.

[0042] The parts not described in detail in the present invention are all conventional technical means known to those skilled in the art.

[0043] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0044] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
