Description

Technical Field

[0001] The utility model belongs to the field of water treatment, relates to the technical field of separation of water and suspended matter, and specifically relates to a high-efficiency ribless transverse split-flow inclined plate module. Background Art

[0002] Existing water treatment sedimentation processes include: advection sedimentation, inclined tube sedimentation, and inclined plate sedimentation. Among them, advection sedimentation occupies the largest area, followed by inclined tube sedimentation, and inclined plate sedimentation occupies a relatively small area.

[0003] The horizontal split-flow inclined plate sedimentation process is developed based on the shallow sedimentation theory. Compared with other sedimentation processes, the sedimentation area of ​​one inclined plate is more than twice that of an ordinary sedimentation inclined plate. The horizontal split-flow inclined plate sedimentation process eliminates the clear water area of ​​the sedimentation tank and the upper water collection tank, allowing the water flow and the sediment to go their own way, solving the long-standing contradiction between the sinking of particles in the inclined tube sedimentation process and the reverse collision of the clear water rising against the particles, greatly shortening the particle sedimentation time and distance, and the sedimentation effect is twice that of the sedimentation device of the same area, ensuring efficient sedimentation and effluent water quality, and reducing the processing load of the subsequent filtration process.

[0004] At present, the transverse diversion inclined plate contains ribs, but the existence of the ribs reduces the flow area to a certain extent, resulting in excessive horizontal flow velocity in the sedimentation tank and reduced sedimentation efficiency. That is, under the condition of the same flow area, the surface load of the inclined plate increases. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a high-efficiency ribless transverse diversion inclined plate module for use in the field of water treatment. By eliminating the ribs, the flow area is increased and the horizontal flow velocity of the sedimentation tank is reduced, thereby greatly improving the sedimentation efficiency. The inclined plate is fixed to the frame by fixing parts to eliminate the deformation of the inclined plate. At the same time, factory assembly modularization is realized to improve the installation and construction efficiency.

[0006] The utility model is realized through the following technical solutions.

[0008] Furthermore, the frame is provided with a positioning plate, the positioning plate has a plurality of first slots arranged at equal intervals, the fixing member is provided with a second slot, and the fixing member is clamped on the positioning plate to fix the inclined plate on the frame.

[0009] Furthermore, the fixing member adopts a single-plate structure, including a fixing portion and a clamping portion, the fixing portion is fixed on the bottom plate, the clamping portion is a portion extending to both ends of the fixing portion, and the clamping groove is opened on the clamping portion.

[0010] Furthermore, a pressing piece is used to press the clamping portion and welded to the frame to keep the inclined plate in a tensioned state, or the clamping portion is welded to the positioning plate to keep the inclined plate in a tensioned state.

[0011] Furthermore, lifting ears are provided on both sides of the upper surface of the bottom of the frame.

[0012] Furthermore, the inclined plates are arranged at equal intervals with a spacing of 95 to 120 mm, and there are mud sedimentation channels between the inclined plates.

[0013] Furthermore, the inclined plate is made of plastic, metal or alloy. If plastic is used, the bottom plate and the wing are injection molded or welded. If metal or alloy is used, the wing is welded to the bottom plate.

[0030] The following is a further description of the structures involved in the present invention or the technical terms used. These descriptions are merely examples of how the present invention is implemented and do not constitute any limitation to the present invention.

[0031] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left" and "right" indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the positions or elements referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limitations of the present invention. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0032] In the description of the present invention, unless otherwise clearly specified and limited, "connection", "fixation" and the like should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] like Figure 1-10 As shown, a high-efficiency ribless transverse diversion inclined plate module for water treatment field includes a frame 1 and a plurality of inclined plates 2 arranged inside the frame, the inclined plates 2 include a bottom plate 21, fins 22 and fixing members 23 placed at the upper and lower ends of the bottom plate 21, the fins 22 are placed on the bottom plate 21 and arranged in a horizontal tilt, the fixing members 23 fix the inclined plates 2 on the frame 1 and make the inclined plates 2 tensioned, and each inclined plate 2 is independent of each other.

[0034] The fixings 23 fix the inclined plate 2 on the frame 1 and keep the inclined plate 2 in a tensioned and straightened state. Each inclined plate 2 is independent of each other. Not only is the entire inclined plate surface smooth without obstructions such as ribs, the flow area is increased, the horizontal flow velocity of the sedimentation tank is reduced, and the sedimentation efficiency is greatly improved. The area of ​​the sedimentation zone is also reduced. At the same time, the surface load of the inclined plate 2 is reduced, and the inclined plate 2 is fixed to the frame 1 by the fixings 23 to eliminate the deformation of the inclined plate 2 and keep the inclined plate 2 in a tensioned and straightened state, thereby achieving a good mud sliding effect. Among them, each inclined plate 2 is independent of each other means that there is no contact or stacking between the inclined plates 2. The flow rate passing through the unit sedimentation area of ​​the inclined plate is called the surface load, that is, when the water flow rate is constant, the sedimentation area of ​​the inclined plate 2 increases after the ribs are removed, and the surface load of the inclined plate 2 decreases.

[0035] As some optional embodiments, Figure 6 As shown, the frame 1 is provided with a positioning plate 3, the positioning plate 3 has a plurality of first card slots 31 arranged at equal intervals, and the fixing member 23 is provided with second card slots 231 at both ends. The fixing member 23 is clamped on the positioning plate 3 to fix the inclined plate 2 to the frame 1. The inclined plates 2 are arranged at a certain interval by the positioning plate 3. At the same time, the inclined plates 2 are clamped with the positioning plate 3 on the frame 1 through the fixing member 23, so that the inclined plates 2 are fixed in the front-back and left-right directions, and are easy to install. As a specific embodiment, the inclination angle of the first card slot 31 is consistent with the installation inclination angle of the inclined plate 2, which is 60°.

[0036] As some optional embodiments, the fixing member 23 may be a single plate structure, or may be formed by extending from the bottom plate 21 to both sides. When the fixing member 23 is formed by extending from the bottom plate 21 to both sides, the extended portion may be integrally formed with the bottom plate 21, such as by injection molding, stamping molding, laser cutting molding, or may be welded to the bottom plate 21.

[0037] As some optional embodiments, Figure 3 and 4 As shown, the fixing member 23 is a single-plate structure, including a fixing portion 232 and a clamping portion 233, the fixing portion 232 is fixed to the bottom plate 21, the clamping portion 233 is a portion of the fixing portion 232 extending to both ends, and the second clamping groove 231 is opened on the clamping portion 233. As a specific embodiment, the second clamping groove 231 is opened at the lower end of the clamping portion 233.

[0038] Due to the insufficient rigidity of the inclined plate, the large span and the insufficient clamping force, the fixing member 23 moves back, causing the inclined plate 2 to be concave to a certain extent, which affects the slipping of mud. Therefore, the fixing member 23 needs to be completely fixed to make the inclined plate 2 in a tensioned and straightened state, which will achieve a better slipping effect. As some optional embodiments, a pressing member 4 is used to press the clamping portion 233 and weld it to the frame 1 or the positioning plate 3 to keep the inclined plate 2 in a tensioned state. The pressing member 4 is a pipe fitting, a column fitting, etc., such as a square pipe, a round pipe, a square column, a round column, etc. At this time, the portion of the clamping portion 233 extending out of the positioning plate 3 has a certain length, so that the pressing member 4 can contact and press it, or the clamping portion 232 is directly welded to the frame 1 or the positioning plate 3 to keep the inclined plate 2 in a tensioned state.

[0039] As some optional embodiments, Figure 5 As shown, the frame 1 includes a bottom frame 11, a top frame 12 and a frame, and the bottom frame 11, the top frame 12 and the frame are formed by overlapping slender members. Among them, the slender members are square tubes, round tubes, etc. The bottom frame 11 is used to support the inclined plate 2, the top frame 12 is used to place the inclined plate 2 in the frame 1, and the frame is used to fix the inclined plate 2 in the upper and lower triangular areas so that it does not have spatial displacement such as left and right, front and back.

[0040] As some optional embodiments, the fixing member at the upper end of the bottom plate 21 is an upper fixing member 234, the fixing member at the lower end of the bottom plate 21 is a lower fixing member 235, the internal space of the frame 1 is divided into an upper triangular area 14, a middle area 15 and a lower triangular area 16, positioning plates 3 are provided on both sides of the bottom frame 11 and are arranged on the upper surface of the bottom frame 11, positioning plates 3 are provided on both sides of the top frame 12 and are arranged on the upper surface of the top frame 12, the frame includes a left frame 131 and a right frame 132, the inner side of the left frame 131 is provided with a positioning plate 3, and the inner side of the right frame 132 is provided with a positioning plate 3, see Figure 5 .

[0041] The inclined plate of the upper triangular area 14 is clamped downwardly on the positioning plate of the top frame 12 through the upper fixing member 234, and the lower fixing member 235 is clamped downwardly on the positioning plate of the left frame 13. The inclined plate of the lower triangular area 16 is clamped downwardly on the positioning plate of the right frame 132 through the upper fixing member 234, and the lower fixing member 235 is clamped downwardly on the positioning plate of the bottom frame 11. The inclined plate 2 of the middle area 15 is clamped downwardly on the positioning plate of the top frame 12 through the upper fixing member 234, and the lower fixing member 235 is clamped downwardly on the positioning plate of the bottom frame 11, so that the inclined plate 2 is formed inside the frame 1 as shown in the figure. Figure 1 The inclined plates 2 of the upper triangular area 14 are arranged at a fixed interval. At this time, the operation of keeping the inclined plates 2 of each area in a tensioned state is: the inclined plate of the upper triangular area 14 only presses the clamping portion 232 of the lower fixing member 235 through the pressing piece 4 and is welded to the frame 1, the inclined plate of the lower triangular area 16 only presses the clamping portion 232 of the lower fixing member 235 through the pressing piece 4 and is welded to the frame 1, and the inclined plate of the middle area 15 only presses the clamping portion 232 of the lower fixing member 235 through the pressing piece 4 and is welded to the frame 1, see Figure 7-10 .

[0042] As some optional embodiments, Figure 5 As shown, the upper surface of the bottom frame 11 is provided with lifting ears 5 on both sides. As a specific embodiment, there are two lifting ears 5 on each side, which are arranged front and back. The specific number can be set according to actual needs. The lifting ears 5 are used for on-site lifting after the inclined plate formwork is assembled as a whole, so as to improve the installation and construction efficiency.

[0043] As some optional embodiments, Figure 2 As shown, the inclined plates 2 are arranged at equal intervals, and the interval L1 is 95-120 mm. There are mud channels 24 between the inclined plates 2 to facilitate the sliding of the mud. As a specific embodiment, the interval between the inclined plates 2 is 95 mm, which can be adjusted according to different water quality conditions.

[0044] As some optional embodiments, Figure 2 As shown, the inclined plate 2 is installed at an angle of 60°, and the included angle between the wing 22 and the bottom plate 21 is 60°, and the mud-water separation effect is optimal. The inclined plate installation angle refers to the angle between the inclined plate and the horizontal plane after installation.

[0045] As some optional embodiments, Figure 2 As shown, the fins 22 are arranged equidistantly, and the spacing L2 is 40 to 80 mm. As a specific embodiment, the spacing between the fins 22 is 60 mm. The existence of the equidistant fins 22 shortens the sedimentation distance of the suspended matter in the sedimentation tank, and at the same time, due to the reduction of the overall flow rate, the suspended matter is easier to settle, thereby improving the sedimentation efficiency.

[0046] As an optional embodiment, the inclined plate 2 is made of plastic, metal or alloy, such as PP, PVC, ABS, stainless steel, etc. If plastic is used, the bottom plate 21 and the fins 22 are injection molded or welded, and if metal or alloy is used, the fins 22 are welded to the bottom plate 21.

The upper and lower triangular area inclined plates are made of inclined plates of different lengths, the wing 22 is made of rolling forming cutting technology or shearing and bending technology, and the fixing part 23 is made of laser cutting or shearing and stamping technology to form a card slot. The processing of a single inclined plate adopts argon arc welding, laser welding or resistance welding and other welding processes to weld and assemble the bottom plate 21, the wing 22 and the fixing part 23 together.

[0048] like Fig.11 As shown, the transverse split-flow inclined plate module is installed in the sedimentation tank, and the water flow direction is parallel to the wing, that is, the water flow direction is perpendicular to the direction of sludge sliding down, which has little effect on the sludge sliding down and can obtain an ideal sedimentation effect.
