Description

Technical Field

[0001] The utility model belongs to the technical field of wastewater treatment and relates to a sand abrasive sedimentation device, in particular to a lithium iron phosphate sand abrasive sedimentation device. Background Art

[0002] In the prior art, lithium iron phosphate is a lithium-ion battery electrode material, mainly used in various lithium-ion batteries. Lithium iron phosphate is a new type of lithium-ion battery electrode material. It is characterized by large discharge capacity, low price, non-toxicity, and no environmental pollution. When lithium iron phosphate sand is produced and processed, it needs to be polished with abrasives. When the abrasive is used, a lithium iron phosphate sand abrasive sedimentation device is required to sediment it. When the existing sedimentation device is used, it mainly uses the gravity of the water flow for self-filtration. Not only is the filtration time long, but the filtration efficiency is also low, which delays the production of the enterprise. Utility Model Content

[0003] In order to solve the above deficiencies in the prior art, the utility model aims to provide a lithium iron phosphate sand abrasive settling device to reduce the filtration time of the lithium iron phosphate sand abrasive settling device and improve the filtration efficiency.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A lithium iron phosphate abrasive sedimentation device, comprising a bracket, a device body, a base fixedly connected to the right side of the top of the device body, a motor fixedly connected to the top of the base, an eccentric wheel fixedly connected to the output end of the motor, a rotating shaft fixedly connected to the outer ring of the eccentric wheel, a transmission column rotatably connected to the outside of the rotating shaft, a connecting column rotatably connected to the bottom end of the transmission column, the connecting column passes through the top of the device body, and a pressure plate fixedly connected to the bottom end; a filter screen is arranged between the pressure plate and the top of the device; a feed port is arranged through the outside of the device body, and a discharge port is arranged at the bottom of the device body;

[0006] The inside of the device body is a sealed space. The pressure plate divides the device body into two independent spaces. When the pressure plate moves downward, the upper space expands and the internal pressure becomes lower, so that suction is generated in the upper space, which can suck the material into the device body, making feeding easier and reducing the energy consumption of feeding.

[0007] As a limitation of the present invention, a one-way water blocking mechanism is provided inside the discharge end of the feed port and inside the feed end of the discharge port;

[0008] By setting up a water blocking mechanism, it is possible to prevent the pressure inside the device body from changing during the movement of the pressure plate, causing the material to flow back;

[0009] As another limitation of the present invention, a plurality of water holes are evenly arranged on the pressure plate, and a one-way water blocking mechanism is arranged in each water hole;

[0010] As a further limitation of the present utility model, the one-way water blocking mechanism includes a limiting ring, a rotating shaft is fixedly arranged in the middle of the limiting ring, and water blocking sheets are rotatably arranged on both sides of the rotating shaft;

[0011] By opening a through hole on the pressure plate and setting a one-way water blocking mechanism, the pressure plate can transfer the settled water phase to the bottom of the pressure plate when it moves upward, and when the pressure plate moves downward, the water phase is squeezed out of the discharge port while avoiding the backflow of the water phase, so that the water phase can enter the next step of treatment faster;

[0012] As a third limitation of the present invention, the filter screen is arranged obliquely, and the end close to the feed inlet is the low end, and the end away from the feed inlet is the high end;

[0013] Setting a certain inclination angle for the filter can reduce the retention time of the solid phase in the filter, improve the utilization rate of the filter, and facilitate the cleaning of the filter;

[0014] As a fourth limitation of the present utility model, the bottom of the device body is funnel-shaped;

[0015] The bottom of the device body is set to be funnel-shaped, which is conducive to the discharge of the water phase, avoids the residual water phase after sedimentation inside the device body, and reduces the difficulty of cleaning the inside of the device body.

[0016] Due to the adoption of the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0017] (1) The utility model relates to a lithium iron phosphate abrasive sedimentation device, which is provided with a pressure plate inside so that the pressure plate divides the device body into two independent spaces inside. When the pressure plate moves downward, the upper space expands and the internal pressure becomes lower, so that suction is generated in the upper space, and the material can be sucked into the device body, making feeding simpler and easier, and reducing the energy consumption and feeding time of feeding;

[0018] (2) The utility model relates to a lithium iron phosphate abrasive sedimentation device, which is provided with a filter screen above the pressure plate. When the pressure plate moves upward, it drives part of the water phase to flow back to impact the filter screen, which can promote the separation of the solid phase on the filter screen from the filter screen, avoid the solid phase particles from clogging the filter holes of the filter screen, reduce the difficulty of cleaning the filter screen, and at the same time improve the filtration efficiency and shorten the filtration time;

[0019] (3) The utility model relates to a lithium iron phosphate abrasive sedimentation device, which can reduce the retention time of the solid phase in the filter screen by setting a certain inclination angle on the filter screen, thereby improving the utilization rate of the filter screen and facilitating the cleaning of the filter screen;

[0020] (4) The lithium iron phosphate abrasive sedimentation device of the utility model is configured to have a funnel-shaped bottom portion of the device body, which facilitates the discharge of the water phase, avoids the water phase remaining inside the device body after sedimentation, and reduces the difficulty of cleaning the inside of the device body;

[0021] In summary, the lithium iron phosphate sand abrasive sedimentation device involved in the utility model can effectively reduce the filtration time of the lithium iron phosphate sand abrasive sedimentation device and improve the filtration efficiency.

[0022] The utility model is suitable for treating waste lithium iron phosphate sand abrasive material liquid and is used for settling waste lithium iron phosphate sand abrasive material. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and understand the present invention, and are not used to limit the present invention.

[0029] Embodiment A lithium iron phosphate abrasive sedimentation device

[0030] like Figures 1 to 3As shown, this embodiment relates to a lithium iron phosphate abrasive sedimentation device, including a bracket 2, a device body 1, a base 12 is fixedly connected to the right side of the top of the device body 1, a motor 3 is fixedly connected to the top of the base, an eccentric wheel 4 is fixedly connected to the output end of the motor 3, the outer ring of the eccentric wheel 4 is fixedly connected to a rotating shaft, the outer part of the rotating shaft is rotatably connected to a transmission column 5, the bottom end of the transmission column 5 is rotatably connected to a connecting column 6, the connecting column 6 passes through the top of the device body 1, and a pressure plate 8 is fixedly connected to the bottom end; a filter screen 7 is arranged between the pressure plate 8 and the top of the device body 1; a feed port 11 is arranged through the outside of the device body 1, and a discharge port 10 is arranged at the bottom of the device body;

[0031] A one-way water blocking mechanism 9 is provided inside the discharge end of the feed port 11 and inside the feed end of the discharge port 10;

[0032] A plurality of water holes are evenly arranged on the pressure plate 8, and a one-way water blocking mechanism 9 is arranged in each water hole;

[0033] The one-way water blocking mechanism 9 comprises a limiting ring 13, a rotating shaft 14 is fixedly arranged in the middle of the limiting ring 13, and water blocking sheets 15 are rotatably arranged on both sides of the rotating shaft 14;

[0034] The filter screen 7 is tilted, with the end close to the feed inlet 11 being the lower end and the end away from the feed inlet 11 being the higher end;

[0035] The bottom of the device body 1 is funnel-shaped.

[0036] When the present embodiment is used, the power is turned on, the motor 3 drives the eccentric wheel 4 to rotate, and the transmission column 5 and the connecting column 6 are driven by the rotating shaft, so that the pressure plate 8 fixed at the bottom of the connecting column 6 reciprocates up and down;

[0037] When the pressure plate 8 moves downward, the space above the pressure plate 8 becomes larger, the pressure becomes smaller, and the abrasive mixture of lithium iron phosphate is drawn out through the feed port 11. The abrasive mixture impacts the one-way water blocking mechanism 9 at the discharge port of the feed port 11, so that the water blocking sheet 15 of the one-way water blocking mechanism 9 in the feed port 11 rotates toward the inside of the device body 1 through the rotating shaft 14, so that the abrasive mixture enters the device body 1 and impacts the filter screen 7 arranged inside, and is filtered and settled.

[0038] When the pressure plate 8 moves upward, the upper space of the device body 1 is compressed and the pressure increases. The water blocking sheet 15 in the one-way water blocking mechanism 9 arranged on the pressure plate 8 and the discharge port 10 opens downward, and the filtered water phase is discharged to the discharge port 10. At the same time, part of the water phase will be driven by the pressure plate to flow back. The backflowing water phase flushes the filter screen 7 to flush the filtered solid phase out of the filter holes of the filter screen 7, and the water blocking sheet 15 of the one-way water blocking mechanism 9 in the feed port 11 rotates toward the inside of the feed port 11 due to the reverse pressure, closes the feed port 11, and prevents the sand and abrasive mixture from flowing back.

[0039] It should be noted that the above is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
