Description

Technical Field

[0001] The utility model belongs to the technical field of sedimentation tanks and relates to a folding plate of a sedimentation tank, in particular to a folding plate structure of a sedimentation tank. Background Art

[0002] In water plants, sedimentation tanks are usually used to treat sewage. Several folding plates are fixed at intervals in the sedimentation tank. Sewage and flocculants are poured into the sedimentation tank for mixing. The mixed water enters from the entrance of the sedimentation tank, flows in a zigzag manner when passing through the folding plates of the sedimentation tank, and the treated water flows out from the outlet of the sedimentation tank. There are the following problems:

[0003] 1. The two sides of the traditional folding plate are directly fixed on the two side walls of the sedimentation tank, which requires high installation accuracy. Once deviation or misalignment occurs, not only the folding plate cannot be installed smoothly, but also the installation of other folding plates will be affected; and rework is time-consuming and labor-intensive, with high construction costs and low efficiency;

[0004] 2. When sewage flows to the bottom of the sedimentation tank, the water pressure is usually large, and the impact force on the bottom of the folding plate is large, causing the folding plate to be easily deformed and have a short service life. The deformation of the folding plate affects the normal flow of water, resulting in a poor sedimentation effect.

[0005] To this end, we propose a folded plate structure for a sedimentation tank to solve the above problems. Utility Model Content

[0006] The utility model aims to overcome the deficiencies of the prior art and provide a folding plate structure of a sedimentation tank which has stable operation and simple structure.

[0007] To solve the above problems, the technical solution of the utility model is:

[0008] A folded plate structure of a sedimentation tank, wherein a water inlet is arranged at one end of the sedimentation tank and a water outlet is arranged at the other end, comprising:

[0009] The folding plate assembly is vertically arranged in the sedimentation tank, and the two ends are respectively fixedly installed on the two side walls of the sedimentation tank through the mounting parts;

[0010] The folding plate assembly is fixedly installed with a diverter device, which is suitable for diverting the water flowing to the diverter device;

[0011] The folding plate assembly comprises a plurality of upper folding plates and a plurality of lower folding plates, wherein the plurality of upper folding plates and the lower folding plates are arranged alternately, and a curved water flow channel is formed between the upper folding plates and the lower folding plates.

[0012] In a further embodiment, a diverter device is fixedly mounted on the bottom end of one or more lower folding plates.

[0013] In a further embodiment, along the water flow direction, the spacing between the plurality of upper folding plates and the plurality of lower folding plates at the front section and the rear section of the sedimentation tank is greater than the spacing between the plurality of upper folding plates and the plurality of lower folding plates at the middle section.

[0014] In a further embodiment, both the upper folding plate and the lower folding plate are bent structures;

[0015] Along the water flow direction, several upper folding plates and lower folding plates located in the front section of the sedimentation tank are symmetrically arranged, and several upper folding plates and lower folding plates located in the middle section and the rear section of the sedimentation tank are parallelly arranged.

[0016] In a further embodiment, the diverter device is a one-way valve, and the direction of the one-way valve is consistent with the direction of the water flow.

[0017] In a further embodiment, a one-way valve is fixedly installed on the lower folding plate located at the front section of the sedimentation tank, or the front section and middle section of the sedimentation tank.

[0018] In a further embodiment, the mounting portion includes a sealing member and a fixing angle which are arranged in sequence, and is fixed to the wall of the sedimentation tank by bolts.

[0019] In a further embodiment, the sealing member is a rubber strip or a sealing tape.

[0020] In a further embodiment, the fixed angle is a bent structure, and its shape corresponds to the upper folding plate and the lower folding plate.

[0021] In a further embodiment, the bending angles of the upper folding plate and the lower folding plate are both 90 degrees.

[0022] Compared with the prior art, the beneficial effects of the utility model are:

[0023] 1. Both ends of the folding plate assembly of the folding plate structure are fixedly installed on the wall of the sedimentation tank through the mounting part. During installation, the mounting part is first fixedly installed on the pool wall, and the position is adjusted to ensure that the position of the mounting part is accurate, and then the folding plate assembly is fixedly installed on the mounting part. This can ensure that the folding plate assembly is installed smoothly and accurately, avoid rework, and have high installation efficiency.

[0024] 2. A one-way valve is fixedly installed at the bottom end of the lower folded plate of the folded plate structure. The direction of the one-way valve is consistent with the direction of the water flow, so that when the sewage flows to the bottom end of the lower folded plate, a small part of the water flows directly through the one-way valve, and then balances the water pressure on both sides of the one-way valve, so that the one-way valve is closed, and the remaining water continues to flow along the channel between the upper folded plate and the lower folded plate, relieving the pressure on the bottom end of the lower folded plate, avoiding deformation of the lower folded plate, and extending the service life.

[0025] 3. The upper and lower folding plates of the front section of the sedimentation tank with this folding plate structure are symmetrically arranged with a large spacing, which alleviates the problem of high water pressure in the front section and facilitates the smooth passage of water; the upper and lower folding plates in the middle section of the sedimentation tank are parallelly arranged with a small spacing, which strengthens the mixing of sewage and flocculant and improves the treatment effect; the upper and lower folding plates in the rear section of the sedimentation tank are parallelly arranged with a large spacing, which allows the water to pass smoothly after the water pressure is reduced, while saving costs, the design is scientific and reasonable, and the service life of the folding plates is extended.

[0031] Embodiment 1:

[0032] A folded plate structure of a sedimentation tank, such as Figures 1 to 3As shown, a vertically arranged folding plate assembly 2 is fixedly installed in the sedimentation tank 1. The folding plate assembly 2 is arranged transversely through-length, and its two side ends are respectively fixedly installed on the two side walls of the sedimentation tank 1; a water inlet 11 is formed at one end of the sedimentation tank 1, and a water outlet 12 is formed at the other end of the sedimentation tank 1. Sewage and flocculant enter the sedimentation tank 1 from the water inlet 11, flow along the water flow direction X, and finally the treated sewage flows out from the water outlet 12.

[0033] like Figure 1 As shown, the folding plate assembly 2 includes a plurality of upper folding plates 21 and a plurality of lower folding plates 22, the plurality of upper folding plates 21 and the plurality of lower folding plates 22 are arranged at intervals, and are all serpentine bending structures, with a bending angle of 90 degrees, which can enhance the mixing effect of sewage and flocculant when water flows through; the upper end of the upper folding plate 21 is a linear structure and is located at the upper part of the sedimentation tank 1, the lower end of the lower folding plate 22 is a linear structure and is located at the lower part of the sedimentation tank 1, and an S-shaped water flow channel is formed between the upper folding plate 21 and the lower folding plate 22, so that the sewage and the flocculant are fully mixed and reacted, and the water flow direction in the water flow channel is as shown in FIG. Figure 1 As shown by the dotted arrow in the middle; since the sewage water pressure in the front section is relatively large and the water flow is relatively fast, and the sewage water pressure in the rear section is relatively small and the water flow is relatively slow, the upper folding plates 21 and the lower folding plates 22 located in the front section are symmetrically arranged along the water flow direction X, that is, the bending angles of the upper folding plates 21 and the lower folding plates 22 are opposite to each other, and the spacing between the upper folding plates 21 and the lower folding plates 22 is relatively large, which relieves the pressure on the upper folding plates 21 and the lower folding plates 22 and improves the service life of the upper folding plates 21 and the lower folding plates 22; the upper folding plates 21 and the lower folding plates 22 located in the middle section are symmetrically arranged along the water flow direction X, that is, the bending angles of the upper folding plates 21 and the lower folding plates 22 are opposite to each other, and the spacing between the upper folding plates 21 and the lower folding plates 22 is relatively large, which relieves the pressure on the upper folding plates 21 and the lower folding plates 22 and improves the service life of the upper folding plates 21 and the lower folding plates 22; The upper folding plate 21 and the lower folding plate 22 are arranged in parallel, that is, the bending angles of the upper folding plate 21 and the lower folding plate 22 are in the same direction, and the spacing between several upper folding plates 21 and lower folding plates 22 is small, which strengthens the mixing of sewage and flocculant and improves the sewage treatment effect; the upper folding plates 21 and the lower folding plates 22 located in the rear section are arranged in parallel, that is, the bending angles of the upper folding plate 21 and the lower folding plate 22 are in the same direction, and the spacing between several upper folding plates 21 and lower folding plates 22 is large, which facilitates the smooth passage of sewage with lower water pressure in the rear section.

[0034] like Figure 2As shown, a diverter 221 is fixedly installed at the bottom end of the lower folding plate 22. The diverter 221 is a one-way valve. The direction of the one-way valve is consistent with the water flow direction X, so that when the sewage flows to the one-way valve, due to the large water pressure, a small part of the sewage directly flows to the other side of the lower folding plate 22 through the one-way valve, which can relieve the water pressure on the lower folding plate 22, avoid deformation of the lower folding plate 22, and extend the service life; and after a small part of the sewage flows to the other side of the lower folding plate 22 through the one-way valve, the water pressure on the other side of the one-way valve increases, balancing the water pressure on both sides of the one-way valve, and then closing the one-way valve, so that the remaining sewage can no longer pass through the one-way valve and continue to flow along the channel between the upper folding plate 21 and the lower folding plate 22, while ensuring that the water flow cannot flow back. Preferably, the diverter 221 is not set in the lower folding plates 22 located in the rear section, or the middle section and the rear section, so that the sewage and the flocculant are fully mixed to ensure the treatment effect.

[0035] like Figure 3 As shown, both ends of the upper folding plate 21 and the lower folding plate 22 are fixedly installed on the pool walls on both sides of the sedimentation tank 1 through the mounting parts 23. During installation, the mounting parts 23 are first fixedly installed on the pool walls of the sedimentation tank 1 to position them to ensure that the installation position is accurate and correct, and then the upper folding plate 21 and the lower folding plate 22 are welded between the two corresponding mounting parts 23 to avoid deviations in the installation of the upper folding plate 21 and the lower folding plate 22 resulting in rework. After welding, pickling and passivation treatment are performed, and there are no defects such as desoldering, sand holes, depressions, scorch marks, cracks, deformation and distortion. The surface is flat, smooth, neat and beautiful; the mounting part 23 includes a sealing member 231 and a fixed angle 232, so that the sealing member 231 is located between the fixed angle 232 and the pool wall of the sedimentation tank 1, and is fixed by bolts to ensure that there is no water leakage at the position where the upper folding plate 21 and the lower folding plate 22 contact the sedimentation tank 1; the fixed angle 232 is a serpentine bending structure, corresponding to the upper folding plate 21 and the lower folding plate 22. Preferably, the seal 231 is a rubber strip or a sealing tape; the fixed angle 232 is made of angle steel with a specification of L60*40*3; the bolt is of model M10*100 and is made of model 316L stainless steel.

[0036] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
