Description

Technical Field

[0001] The invention relates to the technical field of water treatment, in particular to a rapid precipitation device for aqueous battery wastewater. Background Art

[0002] Wastewater that needs to be treated is generated during the production of aqueous batteries. During the cleaning of electrode materials or battery components, a sedimentation device is first needed to perform preliminary treatment on the wastewater to remove large suspended particles and insoluble impurities in the wastewater. After sedimentation, chemical treatment and other steps are used to further remove pollutants to meet water quality treatment standards.

[0003] Sedimentation tanks are a very common type of equipment in sewage treatment systems. They use gravity to deposit suspended solid particles in sewage to the bottom of the tank to achieve the purpose of preliminary water purification. According to the characteristics of sewage and treatment requirements, inclined plate sedimentation tanks are one of the most common sedimentation tanks. Usually, a series of inclined plates are set in the equipment to increase the sedimentation area with sewage during the upward flow of sewage, thereby promoting the sedimentation of solid particles in sewage.

[0004] At present, the inclined plate sedimentation tank usually discharges sewage directly from the water inlet into the sedimentation tank; and this method often causes turbulence due to uneven water inflow; for example, large sediments suddenly fall, causing the local liquid flow velocity at the inlet to be extremely large, driving the sludge that has settled at the bottom or is settling downward to be re-suspended in the water flow, causing the sludge to be transported to the water inlet again, reducing the water quality; the change in local water flow velocity caused by the turbulence phenomenon destroys the sinking and stratification of solid particles during the sedimentation process, thereby reducing the sedimentation effect;

[0005] In addition, the inclined plate sedimentation tank only includes one sedimentation process and is suitable for simple sewage treatment needs. Its treatment capacity is usually relatively limited. Therefore, for situations with higher sedimentation requirements, a multi-stage sedimentation method is usually adopted: one method is to use multiple continuous sedimentation tanks, each of which is designed with different sedimentation conditions, so that the sewage passes through multiple sedimentation tanks for multiple sedimentation to achieve multiple sedimentation effects. This method usually requires sufficiently large equipment and space; another method is to set up multiple sedimentation areas in the same sedimentation tank, each area has different sedimentation functions and sedimentation effects. This method saves space relatively, but the internal structure of the sedimentation tank needs to be designed to be complex enough to ensure fluid separation and sedimentation effects between different areas.

[0006] Therefore, in view of the above technical problems, a sedimentation device is designed, which can not only achieve the effect of multi-stage sedimentation, but also has a simple structure and portability to adapt to various application requirements. Summary of the invention

DETAILED DESCRIPTION

[0038] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0039] Please refer to the attached Figure 1-6 , a water-based battery wastewater rapid sedimentation device, mainly comprising a funnel-shaped shell 1, an auxiliary sedimentation funnel 2 arranged in the funnel-shaped shell 1, a top cover 3, a sewage inlet 5, a clean water outlet 6, a first sludge collection box 7, and a second sludge collection box 7'; the funnel-shaped shell 1 is connected and fixed with the auxiliary sedimentation funnel 2 through a support rod;

[0040] Among them, a gradually expanding annular flow path 11 with a gradually increasing area from top to bottom is formed between the outer surface of the auxiliary sedimentation funnel 2 and the inner surface of the funnel-shaped shell 1; the gradually expanding annular flow path 11 makes the flow velocity gradually decrease when the sewage is precipitated from top to bottom, which not only increases the sedimentation distance between the solid particles in the sewage and the water, but also reduces the occurrence of turbulence, thereby reducing the agitation of the solid particles by the water flow, and further improves the sedimentation efficiency;

[0041] A sewage dispersion assembly 4 is provided on the outer surface of the auxiliary sedimentation funnel 2, near the lower position of the sewage inlet 5; an overflow port 23 is provided on the end of the auxiliary sedimentation funnel 2 away from the sewage inlet 5, near the top of the auxiliary sedimentation funnel 2;

[0042] The inner surface of the auxiliary sedimentation funnel 2 is provided with multiple layers of annular guide plates 21 which are parallel to each other and have the same width; the multiple layers of annular guide plates 21 are inclined downward toward the center of the auxiliary sedimentation funnel 2; the annular guide plate 21 includes an annular guide plate starting end 211, an annular guide plate end 212, and an annular guide plate extension section 213;

[0043] An auxiliary suspended matter settling part 22 with a hollow structure is provided downward from the center of the top of the auxiliary settling funnel 2; the auxiliary suspended matter settling part 22 is further located in the inner ring of the annular guide plate 21 and is spaced apart from the annular guide plate 21; the auxiliary suspended matter settling part 22 is in a truncated cone shape as a whole, and its diameter gradually decreases from top to bottom; the auxiliary suspended matter settling part 22 mainly includes: a clean water discharge channel 221 with a gradually decreasing diameter from bottom to top, an auxiliary suspended matter settling part side wall 222, an auxiliary suspended matter settling part inner cavity 223, and an auxiliary suspended matter settling part top wall 224;

[0044] The sewage dispersion assembly 4 mainly includes a first inclined plate 41, a second inclined plate 42 located at the bottom end of the first inclined plate 41, a fixed rod 43 sleeved with a spring 44, a protruding limit head 45, a lifting connecting rod 46, and a limit rod 47 rotatably connected to the second inclined plate 42; multiple fixed rods 43 pass through the stepped through holes 411 on the first inclined plate 41 and are connected to the auxiliary sedimentation funnel 2.

[0045] Furthermore, the clean water discharge channel 221 is arranged at the center of the inner cavity of the auxiliary suspended matter settling part 22;

[0046] The clean water discharge channel 221 has a clean water discharge channel side wall 2211; the clean water discharge channel side wall 2211, the auxiliary suspended matter sedimentation part side wall 222, and the auxiliary suspended matter sedimentation part top wall 224 are sealed and connected to form the auxiliary suspended matter sedimentation part inner cavity 223; when the clean water passes through the tapered clean water discharge channel 221, the water flow velocity gradually increases, on the one hand, it helps to reduce the accumulation and deposition of coagulated sediment in the channel and keep the channel unobstructed; it prevents solid particles from being discharged together and ensures water quality; on the other hand, the tapered clean water discharge channel 221 also helps to reduce the turbulence of the water flow, making the water flow more stable and ensuring the uniformity and stability of the water quality.

[0047] Further, the starting end 211 of the annular guide plate is connected to the inner surface of the auxiliary sedimentation funnel 2;

[0048] The end 212 of the annular guide plate extends toward the center of the auxiliary sedimentation funnel 2;

[0049] As the auxiliary sedimentation funnel 2 gradually shrinks into a cone shape, each layer of the annular guide plate 21 will extend outward by a certain length compared to the layer above it, forming an annular guide plate extension section 213 .

[0050] The material of the annular guide plate 21 is glass fiber reinforced plastic, stainless steel, polypropylene, etc.

[0051] Solid particles suspended in the water are affected by gravity and settle down along the inclined surface of the annular guide plate 21. Each layer of the annular guide plate 21 guides the sewage to the outer extension section 213 of the annular guide plate of the next layer, guides the water flow in layers, and optimizes the sewage flow path to make the sewage flow path longer; not only can solid particles of different densities be gradually separated, and excessive solid particles can be avoided from being locally deposited on the surface of the annular guide plate 21, reducing the risk of blockage on the surface of the annular guide plate 21; it can also reduce the occurrence of turbulence to a certain extent, so that the fluid forms a relatively stable flow between the multiple layers of the annular guide plates 21, which is conducive to the precipitation of solid particles;

[0052] Further, at one end of the second inclined plate 42 close to the auxiliary sedimentation funnel 2, sliding grooves 422 are respectively provided on its two side surfaces; a sliding rod 421 is slidably connected in the two sliding grooves 422; the sliding rod 421 is connected to the bottom end of the first inclined plate 41 through a lifting connecting rod 46;

[0053] At the end of the second inclined plate 42 far from the auxiliary sedimentation funnel 2, a through groove penetrating the second inclined plate 42 is provided on its side; one end of a limiting rod 47 is connected to the auxiliary sedimentation funnel 2, and the other end of the limiting rod 47 passes through the through groove on the side surface of the second inclined plate 42 to realize rotational connection with the second inclined plate 42.

[0054] Further, the stepped through hole 411 includes a first channel 4111 and a second channel 4112 with different hole diameters; the hole diameter of the first channel 4111 is larger than that of the second channel 4112;

[0055] The diameter of the first channel 4111 is adapted to the protruding limiting head 45 provided at one end of the fixing rod 43; the diameter of the second channel 4112 is just large enough to allow the fixing rod 43 to pass through, so that the first inclined plate 41 can move back and forth on the fixing rod 43.

[0056] Further, the height of the auxiliary sedimentation funnel 2 is less than the height of the funnel-shaped housing 1; preferably, the height of the auxiliary sedimentation funnel 2 is 2 / 3 to 3 / 4 of the height of the funnel-shaped housing 1;

[0057] The top surface diameter of the auxiliary sedimentation funnel 2 is less than the top surface diameter of the funnel-shaped housing 1; preferably, the top surface diameter of the auxiliary sedimentation funnel 2 is 3 / 4 to 5 / 6 of the top surface diameter of the funnel-shaped housing 1;

[0058] The inclination angle of the outer wall of the auxiliary sedimentation funnel 2 with the horizontal plane is a; the value range of a is 20° to 50°;

[0059] The inclination angle of the outer wall of the funnel-shaped housing 1 with the horizontal plane is b; the value range of b is 35° to 65°; a < b; so that a gradually expanding annular flow path 11 with an area gradually increasing from top to bottom is formed between the outer surface of the auxiliary sedimentation funnel 2 and the inner surface of the funnel-shaped housing 1;

[0060] The height of the auxiliary suspended matter sedimentation part 22 is less than the height of the auxiliary sedimentation funnel 2; preferably, the height of the auxiliary suspended matter sedimentation part 22 is 2 / 3 to 3 / 4 of the height of the auxiliary sedimentation funnel 2;

[0061] The inclination angle of the side wall 222 of the auxiliary suspended matter sedimentation part with the horizontal plane is c, and c = a.

[0062] Furthermore, the lower surface of the top cover 3 is provided with a plurality of slots to achieve sealing engagement with the top of the funnel-shaped housing 1 and the auxiliary sedimentation funnel 2; a clean water outlet 6 is provided at the center of the top cover 3, and the clean water outlet 6 is communicated with the clean water discharge channel 221;

[0063] The lower surface of the top cover 3 is fixedly connected to the top of the auxiliary suspended matter settling part 22 .

[0064] There is a certain distance between the first inclined plate 41 and the inner wall of the funnel-shaped shell 1, and the first inclined plate 41 is arranged to be inclined downward toward the inner wall of the funnel-shaped shell 1;

[0065] Furthermore, the clean water outlet 6 is sealed and connected to a hose, and the destination guided by the hose is at a lower position. A sufficient height difference is formed between the clean water outlet 6 and the water outlet of the hose to cause a siphon effect, so that the clean water can be quickly discharged without additional power energy. The structure is simple, saving energy and cost.

[0066] Specific working method: the sewage to be precipitated enters from the sewage inlet 5 at a stable flow rate, passes through the sewage dispersion component 4, moves along the second inclined plate 42 and falls down to precipitate. Figure 4 As shown, the arrow m in the figure shows the approximate path of the sewage moving along the second inclined plate 42; when the incoming sewage flow is unstable and suddenly increases, the impact force of the water flow velocity is enhanced, and the impact force partially acts on the first inclined plate 41, causing the first inclined plate 41 to move toward the auxiliary sedimentation funnel 2 on the fixed rod 43, and then the lifting connecting rod 46 drives the sliding rod 421 to slide in the slide groove 422 toward the auxiliary sedimentation funnel 2, and finally drives the second inclined plate 42 close to the funnel-shaped shell 1. The end rotates upward, so that in addition to being able to settle downward from the above-mentioned m direction, the sewage can also be dispersed downward from both sides of the second inclined plate 42 to reduce the impact force of the water flow; further, it can prevent the sewage at the upper end from suddenly falling, and its impact force locally forms turbulence, resulting in secondary suspension, affecting the filtering effect.

[0067] The downward sewage flows and settles along the gradually expanding annular flow path 11, and the particulate matter quickly settles to the first sludge duct 8 and is collected in the first sludge collecting box 7; further, the sewage with suspended particulate matter that has been purified to a certain extent flows into the auxiliary sedimentation funnel 2 from the overflow port 23, and passes through the multi-layer annular guide plates 21, and after forming continuous multiple sedimentations between different levels from top to bottom, the suspended particulate matter settles at the bottom of the auxiliary sedimentation funnel 2, and is collected in the second sludge collecting box 7' through the second sludge duct 8'; the clean water after the secondary sedimentation flows to the clean water discharge channel 221, and is finally sucked into the hose from the clean water outlet 6 and collected.

[0068] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
