Description

Technical Field

[0001] The present invention belongs to the technical field of solid-liquid separation, and particularly relates to a winding tube filler with a simple structure, high precipitation efficiency, strong adaptability, and good sludge discharge effect, and a sedimentation tank vertically installed with the winding tube filler. Background Art

[0002] Sedimentation is one of the most commonly used solid-liquid separation technologies. According to the principle of shallow pond sedimentation, the sedimentation efficiency of a sedimentation tank is mainly determined by the sedimentation area. Therefore, adding inclined plates or inclined tubes to the sedimentation tank can greatly increase the sedimentation area of the sedimentation tank, thereby improving the sedimentation efficiency. Currently, the inclined plates or inclined tubes in the sedimentation tank are generally straight components, and usually need to be installed at an inclination of 60° during actual installation; due to the inclination angle existing after the installation of the inclined plates or inclined tubes, there are vacancies of inclined plates or inclined tubes in some areas of the sedimentation tank, making this part of the area an ineffective area for sedimentation, and thus it is difficult to improve the sedimentation efficiency; also, because the inclined tubes or inclined plates need to be installed obliquely, the inclined tubes or inclined plates are mainly installed in rectangular sedimentation tanks such as rectangular and square ones, and it is difficult to install them in circular or irregularly shaped sedimentation tanks, making the application of the inclined plates or inclined tubes relatively limited.

[0003] In the prior art, in order to solve the deficiencies of the inclined plates or inclined tubes in the sedimentation tank, there is a method of reducing the surface load, that is, reducing the ratio of the unit flow rate to the sedimentation tank area, so as to extend the residence time of the turbid water in the sedimentation tank, create more abundant time for particle sedimentation, and thus prompt more particles to have enough time to settle to the bottom of the tank; however, reducing the surface load will lead to a decrease in sedimentation efficiency, thus requiring an expansion of the sedimentation tank area, resulting in a significant increase in construction costs. For this reason, there is a solution of adding a flocculant to the sedimentation tank to promote the combination of suspended substances in the turbid water to accelerate sedimentation; but the continuous use of the flocculant will bring relatively high chemical costs, and improper control of the flocculant dosage will also affect the subsequent treatment process and pose potential hazards to the environment and the health of operators. In addition, there is also a method of alternately arranging multiple layers of inclined tubes or inclined plates in the sedimentation tank to increase the sedimentation area and shorten the sinking distance of the particles, thereby improving the overall sedimentation efficiency; but the alternate arrangement of multiple layers of inclined tubes or inclined plates is not only more difficult to arrange, but also the multiple layers of inclined tubes or inclined plates are prone to clogging problems after being used for a period of time, which will increase the difficulty and cost of cleaning and maintenance. In addition, there is also a method of setting longitudinal diversion (or partition) walls in the sedimentation tank to make the water flow in the tank more stable, effectively avoiding adverse water flow phenomena such as short circuit flow, uneven flow, and density flow, so as to reduce the interference of the water flow on particle sedimentation, thereby improving the sedimentation efficiency; but because the design and construction of the diversion (or partition) walls require professional technicians to carry out precise calculations and careful construction, unreasonable design or poor construction quality may exacerbate the water flow disorder, and adding the diversion (or partition) walls will divide the sedimentation tank into multiple sedimentation chambers, thus increasing the difficulty of sediment cleaning.

[0004] Therefore, researching a filler for sedimentation tanks and a sedimentation tank with a simple structure, high sedimentation efficiency, strong adaptability, and good sludge discharge effect has important practical significance for improving the sedimentation efficiency of existing sedimentation tanks. Summary of the Invention

[0005] To solve the problems mentioned in the above background art, the present invention provides a winding tube filler with a simple structure, high sedimentation efficiency, strong adaptability, and good sludge discharge effect, and also provides a sedimentation tank vertically installed with the winding tube filler.

[0006] The winding tube filler of the present invention is realized as follows: The winding tube filler includes at least two pipes wound around each other along the length direction, and pipe clamps fixed on the outside of the wound pipes to stabilize the relative positions of the pipes. When the winding tube filler is placed vertically, the inner walls and outer walls of each pipe form an angle greater than 30° and less than 70° with the horizontal plane.

[0007] Further, the pipe clamps are square, rectangular, circular, or hexagonal sleeves, and the pipe clamps are fixedly wrapped at both ends of the wound pipes of the winding tube filler or wrapped along the entire length.

[0008] Further, the pipes of the winding tube filler are cross-spirally wound or co-spirally wound.

[0009] The sedimentation tank vertically installed with the winding tube filler of the present invention is realized as follows: It includes a tank body, a water inlet pipe, and a water outlet pipe. The water inlet pipe is fixedly arranged at the lower part on one side of the tank body, and the water outlet pipe is fixedly arranged at the upper part on the side of the tank body away from the water inlet pipe; A number of the aforementioned winding tube fillers are vertically arranged in the tank body, and the inner walls and outer walls of each pipe of the winding tube filler in the tank body form an angle greater than 30° and less than 70° with the horizontal plane.

[0010] Further, the outer walls of the pipe clamps of adjacent winding tube fillers in the tank body are in contact with each other, and the outer walls of the pipe clamps of adjacent winding tube fillers in the tank body are in contact with each other.

[0011] Further, in the blank area between each winding tube filler and the tank wall in the tank body, a winding tube filler with a smaller cross-sectional size is vertically fixed or a sealing filler is filled. The winding tube filler with a smaller cross-sectional size is made by reducing the number of pipes and / or reducing the pipe diameter.

[0012] Further, the water inlet pipe is fixedly arranged below the winding tube filler on one side of the tank body, and the water outlet pipe is fixedly arranged above the winding tube filler on the side of the tank body away from the water inlet pipe.

[0013] Further, a conical sedimentation part is arranged below the water inlet pipe in the tank body, and a sewage pipe and a sewage valve are arranged at the bottom of the conical sedimentation part.

[0014] The present invention has the following beneficial effects: 1. The winding tube filler of the present invention is composed of pipes that are wound around each other and fixed in relative positions. Compared with traditional flat and inclined plates or tubes used as fillers, it can effectively avoid the problem of ineffective areas in some parts of the sedimentation tank caused by the installation inclination angle, increasing the effective sedimentation area. At the same time, the pipes that are wound around each other and fixed in relative positions form slopes on the inner and outer walls of the pipes, which can further increase the effective sedimentation area, ultimately achieving a revolutionary improvement in the utilization rate of the sedimentation space. It also facilitates the sludge discharge under the action of self-weight, thus greatly improving the sedimentation efficiency of the sedimentation tank and being not easily blocked.

[0015] 2. Through hydrodynamic optimization and innovation, the winding tube filler of the present invention is provided with pipes that are helically wound around each other, forming a continuous and gradually changing flow channel. This not only significantly reduces the water flow disturbance compared with traditional flat inclined tubes, but also the micro-vortex effect generated by the cross-helical winding of multiple pipes can promote the collision and aggregation of particles, thereby shortening the sedimentation time and further improving the sedimentation efficiency.

[0016] 3. Through structural design, the winding tube filler of the present invention can be applied to sedimentation tanks of various shapes such as rectangular, circular, and irregular shapes, breaking through the limitation that traditional flat inclined plates or tubes are mainly applicable to rectangular sedimentation tanks, and significantly enhancing the adaptability.

[0017] 4. For the sedimentation tank vertically installed with the winding tube filler of the present invention, by vertically arranging a number of modular-designed winding tube fillers in the tank body, it is not only convenient for the quick disassembly, installation, and replacement of each winding tube filler in the tank body, but also enables the serialization and standardization of the winding tube fillers, so that the winding tube fillers can be mass-produced in factories, which is conducive to reducing the use cost of the winding tube fillers.

[0018] 5. For the sedimentation tank vertically installed with the winding tube filler of the present invention, through the optimization of the relative positions of the inlet pipe, outlet pipe and the winding tube filler of the sedimentation tank, the pipes in the winding tube filler can form a self-cleaning channel under the action of water flow scouring, effectively improving the anti-blocking performance of the pipes. Combined with the conical sedimentation part design at the lower part of the tank body and the sewage pipe and sewage valve, it can completely solve the problem of easy mud accumulation in traditional multi-layer inclined tubes or plates.

[0019] In summary, the present invention has the characteristics of simple structure, high sedimentation efficiency, strong adaptability, and good sludge discharge effect. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but the present invention is not limited in any way. Any changes or improvements made based on the teachings of the present invention fall within the protection scope of the present invention.

[0022] As Figures 1 to 4 shown, for the winding tube packing of the present invention, the winding tube packing 4 includes at least two pipes 5 wound around each other along the length direction, and pipe hoops 6 fixed on the outside of the wound pipes 5 to stabilize the relative positions of the pipes 5. When the winding tube packing 4 is placed vertically, the inner walls and outer walls of the pipes 5 form an angle greater than 30° and less than 70° with the horizontal plane.

[0023] The pipe hoop 6 is a square, rectangular, circular or hexagonal sleeve, and the pipe hoop 6 is fixedly wrapped at both ends of the wound pipes 5 of the winding tube packing 4 or wrapped along the whole length.

[0024] The pipes 5 of the winding tube packing 4 are wound in a cross - helical or co - helical manner.

[0025] As Figures 5 to 8 shown, for the sedimentation tank with winding tube packing vertically installed according to the present invention, it includes a tank body 1, a water inlet pipe 2, and a water outlet pipe 3. The water inlet pipe 2 is fixedly arranged at the lower part on one side of the tank body 1, and the water outlet pipe 3 is fixedly arranged at the upper part on the side of the tank body 1 away from the water inlet pipe 2; a plurality of the aforementioned winding tube packings 4 are vertically arranged in the tank body 1, and the inner walls and outer walls of the pipes 5 of the winding tube packings 4 in the tank body 1 form an angle greater than 30° and less than 70° with the horizontal plane.

[0026] The outer walls of the pipe hoops 6 of adjacent winding tube packings 4 in the tank body 1 are in contact with each other, and the outer walls of the pipe hoops 6 of the winding tube packings 4 near the edge in the tank body 1 are in contact with the tank wall of the tank body 1.

[0027] Inside the pool body 1, winding tube fillers 4 with relatively small cross-sectional dimensions are vertically fixed in the blank areas between each winding tube filler 4 and the pool wall of the pool body 1, or sealed filler 7 is filled. The winding tube fillers 4 with relatively small cross-sectional dimensions are made by reducing the number of pipes 5 and / or reducing the diameter of the pipes 5.

[0028] The water inlet pipe 2 is fixedly arranged below the winding tube filler 4 on one side of the pool body 1, and the water outlet pipe 3 is fixedly arranged above the winding tube filler 4 on the side of the pool body 1 away from the water inlet pipe 2.

[0029] A conical sedimentation part 8 is arranged below the water inlet pipe 2 of the pool body 1, and a sewage pipe and a sewage valve are arranged at the bottom of the conical sedimentation part 8. Example 1

[0030] As Figures 3 to 6 shown, a square sleeve is used as the pipe clamp 6 and fixedly sleeved on the outer side of the winding tube filler 4. The pipe clamps 6 of adjacent winding tube fillers 4 are vertically installed in the square pool body 1 in a mutually fitting manner to form a square sedimentation tank.

And the full length of the square pipe clamp 6 is sleeved on the outside of the four mutually spirally wound pipes 5 to make the relative positions of the pipes 5 stable.

[0032] During operation, the turbid water is introduced into the pool body 1 from the water inlet pipe 2 below the winding tube filler 4, and then the turbid water passes upward through the pipes 5 inside the winding tube filler 4 or between the outer walls of the pipes 5. The suspended solids in the turbid water precipitate on the inner and outer walls of the pipes 5 and slide down the slope under the action of gravity to the conical sedimentation part 8, and the supernatant is discharged from the water outlet pipe 3 above the winding tube filler 4. After sedimentation for a certain period of time, the sewage valve at the bottom of the conical sedimentation part 8 is opened, and the sediment is discharged from the sewage pipe. Example 2

[0033] As Figure 7 and 8 shown, a regular hexagon sleeve is used as the pipe clamp 6 and fixedly sleeved on the outer side of the winding tube filler 4. The pipe clamps 6 of adjacent winding tube fillers 4 are vertically installed in the circular pool body 1 in a mutually fitting manner, and the sealed filler 7 is filled in the blank areas between each winding tube filler 4 and the pool wall of the pool body 1 to form a circular sedimentation tank.
