Description

Technical Field

[0001] The invention relates to the technical field of wastewater separation and filtration, and in particular to a sedimentation and filtration device for water conservancy river channel management. Background Art

[0002] Wastewater in rivers is mainly generated by industrial wastewater discharge, agricultural non-point source pollution and urban domestic sewage discharge. The sources and composition of sewage are very complex, which increases the difficulty of river wastewater treatment. The most direct and low-cost treatment method for river wastewater is solid-liquid separation to reduce the turbidity of water quality. It generally includes two processes: sedimentation and filtration of sewage. Sedimentation generally uses a flocculation sedimentation box, and filtration generally uses a filter element filter. The combination of flocculation sedimentation box and filter can effectively improve the efficiency of solid-liquid separation.

[0003] Existing sedimentation and filtration equipment has many technical defects when in use. First, the design of the sedimentation box is too simple and lacks hierarchy, resulting in poor water quality of the effluent from the sedimentation system, that is, high turbidity, and the sedimentation box cannot adapt the sedimentation function according to the turbidity of the wastewater; second, the filter element filter relies on the infiltration filtration of the wastewater when in use. On the one hand, the fluidity of the wastewater is poor, resulting in a slow infiltration rate. On the other hand, a layer of particulate matter is easily accumulated on the filter membrane, blocking the filter membrane pores, further resulting in a slow infiltration rate and a greatly reduced filtration efficiency; third, after the filter membrane has been used for a certain period of time, a lot of particulate matter will remain on the surface, seriously blocking the filter membrane pores and reducing the filtration efficiency. This problem is generally solved by directly replacing the filter membrane, but disassembly and installation are time-consuming and labor-intensive, and also increase the material loss rate and increase the filtration cost.

[0030] The present invention provides a sedimentation and filtration device for water conservancy river management through improvement, which has the following significant improvements and advantages compared with the prior art: When designing the sedimentation and separation box, the wastewater will first collide and contact with the first interception plate and the second interception plate in the water inlet space, reducing the movement speed and causing the flowing wastewater to move slowly in the inner cavity. Some solids in the wastewater will directly settle downward into the sedimentation bucket due to gravity, and other solids will flow in the guide gap with the fluid and continue to contact the upper surface and protrusion of the coated rubber. With the interception effect of the perforated partition plate, the solids will stay on the surface of the coated rubber after solid adsorption and deceleration, and form precipitation, achieving the effect of layered sedimentation and improving the sedimentation separation effect.

[0031] A raised adjuster is designed, and the cylinder is started. The telescopic rod extends outward, causing the long connecting rod to move linearly. When the moving seat is displaced, the relative movement of the No. 1 inclined sliding surface and the No. 2 inclined sliding surface is used to raise the height of the lifting seat. The lifting seat uses the arc portion to move upward, slowly spreading the corresponding raised portions to make the raised portions bulge, increasing the contact area with the solid, causing multiple groups of raised portions to change at the same time, thereby changing the overall sedimentation performance of the inclined plate sedimentation structure, and better adapting to the needs of sedimentation boxes for wastewaters with different turbidity (or wastewater containing particles in different forms).

[0032] A fine oscillation filter is designed, and a uniform-speed motor is started. The transmission causes the entire horizontal shaft to rotate, and at the same time drives several groups of cams to make circular motion. The cam uses the cam part to contact the contact wheel on the fine oscillation filter during the movement. The two generate an extrusion force that causes the oscillation box to move to the other side, causing the spring steel sheet to bend and deform. When the cam part leaves the contact wheel and the extrusion force disappears, the restoring elastic force of the spring steel sheet drives the oscillation box back to its position. During the reciprocating motion of the oscillation box, the wastewater and particulate matter in the filter chamber flow, and the wastewater applies pressure to the fine filter membrane during the shaking process. The particulate matter avoids clogging the filter membrane holes during the shaking process, thereby increasing the filtration speed of the framed fine filter membrane and improving the filtration efficiency.

[0033] Start the servo motor, and through transmission, the support seat drives the framed fine filter membrane to flip down 90°, so that the framed fine filter membrane is in a vertical state. The degree of automation is high. At the same time, start two sets of high-pressure cleaning pumps, and use the suction pipe to suck clean water, and transport it into the main diversion pipe. Then, it is sprayed out from several sets of injection heads at high pressure. The scattered water flow carries impact force. The injection heads are symmetrically arranged on both sides of each set of fine oscillation filters. Therefore, the two end faces of the framed fine filter membrane can be simultaneously washed with high pressure, which effectively washes away the particles remaining on the filter membrane holes and avoids the direct replacement of the fine filter membrane.

[0052] Specifically, the fine vibration filter 9 includes an outer box body 91, a riveted frame 92 and a second bearing seat 93. Fig.10 shown.

[0057] The contact wheel 98 is provided in two types: fixed type and rotating type (the fixed type means that the contact wheel 98 is fixed on the oscillation box 94, and the rotating type means that the contact wheel 98 is rotatably provided on the oscillation box 94), and a selection is made according to actual needs.

[0058] Furthermore, a mud receiving box 71 is provided directly below the mud discharge pipe 3, and a mud dividing platform 72 is provided in the middle of the mud receiving box 71. The mud blocks falling from the mud dividing platform 72 are diverted to avoid accumulation in the middle of the mud receiving box 71. Figure 1 and 2 shown.

[0059] Furthermore, legs are welded at the four corners of the lower end of the sedimentation separation box 1, and the legs and the secondary filter tank 40 are both located at the upper end of the base 70, playing a role of bearing and supporting. Figure 1 shown.

[0060] When the present embodiment is in use, the wastewater to be treated is continuously and quantitatively injected into the inner cavity 6 of the sedimentation separation box 1 from the water inlet 5 until the wastewater in the inner cavity 6 is higher than the perforated partition 12 and begins to overflow from the drain port 14 (maintaining dynamic water flow balance). At this time, when the wastewater is continuously injected, the wastewater will first collide with the first interception plate 10 and the second interception plate 11 in the water inlet space to reduce the movement speed. The flowing wastewater moves slowly in the inner cavity 6, and some solids (impurities, particulate matter and flocculants) in the wastewater are directly precipitated downward into the sedimentation bucket 2 due to gravity, and the other solids (impurities, particulate matter and flocculants) in the wastewater are directly precipitated into the sedimentation bucket 2 due to gravity. Some solids flow into the flow guide gap 16 with the fluid, climb upward at the positions of several groups of inclined plate bodies 21, and continuously contact the upper surface of the coated rubber 22 and the protrusion 23. After the solid adsorption and deceleration effect, the solids stay on the surface of the coated rubber 22 and form precipitation. After accumulating a certain weight, they move downward and finally fall from the lower end of the inclined plate body 21 into the sedimentation bucket 2. When a certain amount of mud layer is deposited in the sedimentation bucket 2, by opening the discharge valve 73, the mud layer is introduced downward from the mud discharge pipe 3 into the mud receiving box 71 due to gravity, completing the mud and water separation.

[0061] According to the turbidity of the wastewater, the inclined plate sedimentation structure 20 can be adjusted in advance. The specific operation is to start the cylinder 30, and the telescopic rod 31 extends outward, causing the long connecting rod 32 to move linearly, so that the several groups of moving seats 33 on the long connecting rod 32 are all linearly displaced in the limiting groove 36. When the moving seat 33 is displaced, the relative movement of the No. 1 inclined sliding surface 34 and the No. 2 inclined sliding surface 83 is used to lift the height of the lifting seat 81 (the lifting seat 81 is horizontally limited by the two groups of guide splints 37). The lifting seat 81 moves upward using the arc portion 82, slowly stretching the corresponding protrusion 23, so that the protrusion 23 bulges, similar to a ripple with a certain slope, increasing the contact area with the solid, causing multiple groups of protrusions 23 to change at the same time, thereby changing the sedimentation performance of the inclined plate sedimentation structure 20. When the telescopic rod 31 is retracted inward, the lifting seat 81 is slowly reset under the drive of the return elastic force of the two groups of springs 85, so that the slope slowly disappears.

[0062] The precipitated wastewater overflowing from the drain outlet 14 will be injected into the transition diversion box 17 through the guide pipe 15 for temporary storage. The wastewater in the transition diversion box 17 will be slowly injected downward from several groups of water injection pipes 18 in equal amounts and injected into their respective filter chambers 96. Fine filtration will be performed using the framed fine filter membrane 97 to separate fine particles of solid. At this time, the uniform speed motor 46 will be started to drive the No. 1 small gear 45 to rotate, and the No. 1 large gear 44 will be decelerated through meshing, causing the entire horizontal shaft 42 to rotate, while driving several groups of cams 47 to make circular motions. The cam 47 uses the cam part to contact the contact wheel 98 on the fine oscillation filter 9 during the movement, and the two will produce extrusion. The pressure force causes the oscillation box 94 to move to the other side, causing the spring steel sheet 95 to bend and deform. When the cam portion leaves the contact wheel 98 and the squeezing force disappears, the restoring elastic force of the spring steel sheet 95 drives the oscillation box 94 to return to its original position. During the reciprocating movement of the oscillation box 94, the waste water and particulate matter in the filter chamber 96 flow (the waste water applies pressure to the fine filter membrane during the shaking process, and the particulate matter avoids clogging the filter membrane holes during the shaking process), thereby increasing the filtration speed of the framed fine filter membrane 97. This reciprocating process forms a continuous oscillation filtration, and the clean water dripping downward from the framed fine filter membrane 97 is collected at the bottom of the filter tank 41, waiting to be discharged to the outside from the outlet pipe 74. Example 2

[0063] On the basis of the first embodiment, after the framed fine filter membrane 97 has been used for a certain period of time, many particles will remain on the surface, seriously blocking the filter membrane holes and reducing the filtration efficiency. Generally, this problem is solved by directly replacing the framed fine filter membrane 97, but disassembly and installation are time-consuming and labor-intensive, and also increase the material loss rate and filtration cost. In order to solve the above technical problems, we have the following design, such as Figure 11-14 shown.

[0064] Specifically, a movable opening 50 is provided at the bottom of the oscillation box 94, and a framed fine filter membrane 97 is movably installed in the movable opening 50. An inner support seat 52 is provided at the end of the framed fine filter membrane 97. A sealing gasket 53 that interacts with the bottom of the oscillation box 94 is glued to the upper end surface of the inner support seat 52. When the sealing gasket 53 contacts the bottom of the oscillation box 94, the bottom of the oscillation box 94 performs a waterproof seal on the bottom of the filter cavity 96. At this position, the bottom of the oscillation box 94 is concave to form a concave step for the inner support seat 52 to move. Fig.11 and 12 shown.

[0065] Among them, both ends of the inner support seat 52 are welded with shafts 54, and each set of shafts 54 is fixed by the third bearing seat 55 and the box wall of the oscillation box 94, and the shafts 54 move around the third bearing seat 55. Fig.12 shown.

[0066] Among them, a set of shafts 54 extend outwardly and are sleeved with a second large gear 56, and the upper end of the second large gear 56 is meshed with a second small gear 57, and the second small gear 57 is sleeved on the output shaft of a servo motor 58. The servo motor 58 is arranged through the outer side of the oscillation box 94, and the inner support seat 52 drives the framed fine filter membrane 97 to flip downward 90°, such as Fig.12 shown.

[0067] Furthermore, the outer side surface of the secondary filter tank 40 is symmetrically fixed with an outer support seat 60, and the upper end of each group of outer support seats 60 is installed with a high-pressure cleaning pump 61. Fig.13 shown.

[0068] In this embodiment, the water inlet of the high-pressure cleaning pump 61 is connected to a suction pipe 62, which extends to the bottom of the filter tank 41 and is used to suck the clean water in the tank. The water outlet of the high-pressure cleaning pump 61 is connected to a bend pipe 63, and the other end of the bend pipe 63 is connected to a main shunt pipe 64, which is arranged on the tank wall of the filter tank 41. The end of the main shunt pipe 64 away from the bend pipe 63 is fixed by a buckle block 65 and the inner wall of the filter tank 41, as shown in FIG. Fig.13 and 14 shown.

[0069] In this embodiment, a plurality of groups of injection heads 66 are equidistantly connected and arranged on the main flow dividing pipe 64. The injection heads 66 are symmetrically arranged on both sides of each group of fine oscillation filters 9. The injection heads 66 act on both end surfaces of the framed fine filter membrane 97 in an inclined manner downward. The injection range of the injection heads 66 covers the entire fine filter membrane. Fig.13 and 14 shown.

[0070] Furthermore, a waterproof cushion layer is provided on the periphery of the frame of the framed fine filter membrane 97 , and when the waterproof cushion layer contacts the cavity wall of the filter cavity 96 (ie when the framed fine filter membrane 97 is in a horizontal state), the bottom of the filter cavity 96 is waterproofly sealed.

[0071] When the present embodiment is in use, when it is necessary to clean the framed fine filter membrane 97, the servo motor 58 is started to drive the second small gear 57 to rotate, and the second large gear 56 is driven to rotate through meshing reduction, so that the two sets of shaft portions 54 rotate around the third bearing seat 55, and the inner support seat 52 drives the framed fine filter membrane 97 to flip downward 90°, so that the framed fine filter membrane 97 is in a vertical state (the fine filter membrane is located below the oscillation box 94). At this time, the remaining small amount of clean water in the filter tank 41 is used, and the two sets of high-pressure cleaning pumps 61 are turned on at the same time. The clean water is sucked by the suction pipe 62 and transported into the main branch pipe 64, and then sprayed out from a plurality of sets of injection heads 66 at high pressure. The dispersed water flow carries impact force. The injection heads 66 are symmetrically arranged on both sides of each set of fine oscillation filters 9. Therefore, the two end faces of the framed fine filter membrane 97 can be simultaneously high-pressure washed, and the particles remaining on the filter membrane holes are effectively washed away, so that the fine oscillation filter 9 can be used again.

[0073] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
