Description

Technical Field

[0001] This utility model relates to the field of water treatment equipment technology, and in particular to a water treatment flocculant separation device. Background Technology

[0002] Flocculation and sedimentation is an essential step in water treatment, involving the flocculation and sedimentation of particulate matter in water. After adding a coagulant to water, the colloidal and dispersed particles of suspended solids form flocs under the interaction of molecular forces. During sedimentation, these flocs collide and aggregate, continuously increasing in size and mass, and their settling velocity.

[0003] The current flocculation and sedimentation process has some technical defects. After the coagulant is added, it is necessary to wait for the flocs to settle.

[0004] During the reaction, the interaction between the reagent and the pollutants in the water produces foam that floats on the water surface, thus reducing the chance of collision between the reagent and dispersed particles in the water, resulting in a slower rate of flocculation and sedimentation. Utility Model Content

[0005] In view of this, the present invention provides a water treatment floc separation device, the main purpose of which is to improve the rate of flocculation and sedimentation, and at the same time improve the separation efficiency of flocculated sediment.

[0006] To achieve the above objectives, this utility model mainly provides the following technical solutions:

[0007] This utility model provides a water treatment floc separation device, which includes: a tank and a circulation section;

[0008] The circulation section includes a circulation pump, a cyclone separator, a receiving tank, and a spray pipe. The inlet of the circulation pump is connected to the lower end of the pool body, and the outlet of the circulation pump is connected to the tangential inlet of the cyclone separator. The upper outlet of the cyclone separator is connected to the spray pipe, which is located at the upper inlet of the pool body. The lower outlet of the cyclone separator corresponds to the upper inlet of the receiving tank. A discharge valve is installed at the lower outlet of the cyclone separator. An overflow trough is provided around the upper inlet of the receiving tank, and the overflow trough is connected to the upper side wall of the pool body through a connecting pipe.

[0009] The purpose of this utility model and the technical problems to be solved can be further achieved by the following technical measures.

[0010] Optionally, the receiving tank includes an upper receiving tank and a lower receiving tank. The upper inlet of the upper receiving tank corresponds to the lower outlet of the cyclone separator. The upper receiving tank and the lower receiving tank are connected by an isolation valve. A discharge valve is installed at the lower end of the lower receiving tank.

[0011] Optionally, the spray pipe is an annular spray pipe.

[0012] Optionally, it also includes a stirring mechanism, which includes a drive motor and a stirring shaft. The output shaft of the drive motor is coaxially connected to the stirring shaft, and the drive motor is located at the center of the annular spray pipe.

[0013] Optionally, the lower wall of the annular spray pipe is evenly distributed with multiple spiral nozzles.

[0014] By employing the above technical solution, this utility model has at least the following advantages:

[0015] After flocculant is added to the water in the pool, some flocculant accelerates the continuous settling of particles in the water, while some flocculant exists on the water surface in the form of foam. At the same time, the circulating pump pressurizes the water at the bottom of the pool and delivers it to the spray pipe at the top of the pool, and sprays it out to the water surface again, impacting the foam on the water surface. The foam breaks, increasing the probability of collision between the agent and particles in the water, thereby accelerating the formation and settling of flocs.

[0016] Meanwhile, the water output from the circulating pump flows through the cyclone separator, where solid and liquid are separated. The clear water, with its lower specific gravity, reaches the spray pipe through the upper outlet of the cyclone separator, while the flocculent, with its higher specific gravity, settles at the bottom of the cyclone separator. The discharge valve is periodically opened, allowing the flocculent and some clear water to be discharged into the receiving tank. When the receiving tank is full, the clear water enters the overflow tank and flows back to the pool body along the connecting pipe.

[0017] The above-mentioned equipment accelerates the adsorption of particles by flocculants, allowing flocs to form more quickly. At the same time, it also achieves solid-liquid separation, resulting in higher water treatment efficiency. Attached Figure Description

[0020] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the specific implementation methods, structures, features, and effects according to this utility model application are described in detail below with reference to the accompanying drawings and preferred embodiments. In the following description, different "embodiments" or "embodiments" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0022] like Figure 1 As shown, an embodiment of the present invention provides a water treatment flocculant separation device, which includes: a tank body 1 and a circulation section;

[0023] The circulation section includes a circulation pump 2, a cyclone separator 3, a receiving tank 4, and a spray pipe 5. The inlet of the circulation pump 2 is connected to the lower end of the tank body 1, and the outlet of the circulation pump 2 is connected to the tangential inlet of the cyclone separator 3. The upper outlet of the cyclone separator 3 is connected to the spray pipe 5, which is located at the upper inlet of the tank body 1. The lower outlet of the cyclone separator 3 corresponds to the upper inlet of the receiving tank 4. A discharge valve 6 is installed at the lower outlet of the cyclone separator 3. An overflow trough 7 is provided around the upper inlet of the receiving tank 4, and the overflow trough 7 is connected to the upper side wall of the tank body 1 through a connecting pipe 8.

[0024] The working process of a water treatment flocculant separation device is as follows:

[0025] After the flocculant is added to the water in pool 1, some of the flocculant accelerates the continuous sedimentation of particles in the water, while some of the flocculant exists on the water surface in the form of foam. At the same time, the circulating pump 2 pressurizes the water at the bottom of pool 1 and delivers it to the spray pipe 5 at the top of pool 1, and sprays it out to the water surface again, impacting the foam on the water surface. The foam breaks, increasing the probability of collision between the agent and particles in the water, thereby accelerating the formation and sedimentation of flocs.

[0026] Meanwhile, the water output by the circulating pump 2 flows through the cyclone separator 3, where solid and liquid are separated. The water with a lower specific gravity reaches the spray pipe 5 through the upper outlet of the cyclone separator 3. The flocculent with a higher specific gravity settles at the bottom of the cyclone separator 3. The discharge valve 6 is opened periodically to discharge the flocculent and some water into the receiving tank 4. When the receiving tank 4 is full, the water in it enters the overflow tank 7 and flows back to the pool body 1 along the connecting pipe 8.

[0027] In the technical solution of this utility model, the above-mentioned equipment accelerates the adsorption speed of flocculant particles, enabling flocculants to form more quickly. At the same time, it also achieves solid-liquid separation, resulting in higher water treatment efficiency.

[0028] Specifically, the overflow tank 7 is arranged in a ring around the upper inlet of the receiving tank 4. The receiving tank 4 receives the water discharged from the cyclone separator 3 (with a relatively high content of flocculents). The flocculents are concentrated in the receiving tank 4. At the same time, the clean water in the full-level receiving tank 4 enters the overflow tank 7 and flows back to the pool body 1 to ensure the recovery rate of the treated clean water.

[0029] In a specific embodiment, the receiving tank 4 includes an upper receiving tank 401 and a lower receiving tank 402. The upper inlet of the upper receiving tank 401 corresponds to the lower outlet of the cyclone separator 3. The upper receiving tank 401 and the lower receiving tank 402 are connected by an isolation valve 403. A discharge valve 404 is installed at the lower end of the lower receiving tank 402.

[0030] In this embodiment, specifically, when the discharge valve 6 is opened, the isolation valve 403 is also opened simultaneously. Water with a high content of flocculents in the cyclone separator 3 is discharged to the upper receiving tank. After the cyclone separator 3 has finished discharging, the flocculents in it continue to settle into the lower receiving tank for a period of time after the discharge valve 6 is closed. After the discharge valve 6 is opened periodically several times, when there is a lot of flocculents in the lower receiving tank, the isolation valve 403 is closed and the discharge valve 404 is opened to discharge the flocculents in the lower receiving tank 402. During the above discharge process, it will not affect the upper receiving tank 401 receiving the water discharged from the cyclone separator 3.

[0031] In a specific embodiment, the spray pipe 5 is an annular spray pipe 5.

[0032] In this embodiment, specifically, the lower sidewall of the annular spray pipe 5 is evenly distributed with multiple spray holes, which can act on a large water surface area of ​​the pool 1, thereby eliminating foam on the water surface as quickly as possible.

[0033] In a specific embodiment, a stirring mechanism is also included, which includes a drive motor 9 and a stirring shaft 10. The output shaft of the drive motor 9 is coaxially connected to the stirring shaft 10, and the drive motor 9 is located at the center of the annular spray pipe 5.

[0034] In this embodiment, specifically, in the initial stage of adding flocculant to the water in the tank 1, the circulation pump 2 is not started, but the drive motor 9 is started to drive the stirring shaft 10 to rotate, which increases the mixing and diffusion speed of the flocculant in the water. After the flocculant has fully diffused, the circulation pump 2 is started. In this way, the water at the bottom of the tank 1 acts as spray water to impact the foam on the water surface. The spray water also contains a certain amount of flocculant components, which improves the efficiency of flocculation and sedimentation.

[0035] Specifically, the drive motor 9 is located above the center of the circular surface where the annular spray pipe 5 is located, and the spray water is sprayed into the pool body 1 without contacting the drive motor 9.

[0036] Specifically, the drive motor 9 is fixedly installed above the pool body 1 via a frame.

[0037] In a specific embodiment, the lower wall of the annular spray pipe 5 is evenly distributed with multiple spiral nozzles 11.

[0038] In this embodiment, specifically, each spiral nozzle 11 is installed in one of the water spray holes, and the spray water is sprayed out through the spiral nozzle 11, which improves the diffusion degree of the spray water and further expands the water surface area that the spray water can impact.

[0039] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
