Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, in particular to a cyclone rapid coagulation device. Background Art

[0002] Coagulation refers to the process of aggregating colloidal particles and tiny suspended solids in water by some method (such as adding chemical agents). It is a unit operation in water and wastewater treatment processes. Coagulation includes two processes: coagulation and flocculation. Agents that can play a coagulation and flocculation role are collectively referred to as coagulants. In the coagulation process, the coagulant needs to be evenly integrated into the wastewater. Coagulants are used to aggregate and precipitate colloidal particles and tiny suspended solids in water.

[0003] For example, Chinese patent CN221093897U discloses a pressure-type single cyclone coagulation reactor, which relates to the technical field of sewage treatment equipment. The pressure-type single cyclone coagulation reactor includes a reaction tank, a rotating assembly, a material transfer assembly and a linkage assembly. A material box is fixedly installed on the top of the reaction tank, a fixed block is fixedly installed on the inner wall of the material box, a rotating rod is rotatably installed on the inner top of the reaction tank, and blades are fixedly installed on the outer wall of the rotating rod. Sewage and chemicals can be put into the interior of the reaction tank according to the prescribed ratio without measurement. However, the above-mentioned coagulation reactor needs to be stirred and mixed by a motor as a separate power equipment during the mixing process, which will increase the operating cost or maintenance cost of sewage treatment.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0009] Furthermore, in order to achieve the addition of coagulant, a vortex can be generated by the flow of sewage during the sewage injection process, thereby driving the auxiliary plate and the rotating rod to move, and then under the action of the spiral plate, the coagulant inside the feed box is evenly added to the vortex tank body to mix with the sewage to form a suspended solid.

[0024] According to an embodiment of the utility model, a cyclonic rapid coagulation device is provided.

[0025] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods.

In addition, in specific applications, the water inlet direction of the above-mentioned drainage pipe 6 is tangent to the outer wall of the cyclone tank body 1, and a plurality of sewage pipes 7 are arranged on the outer side of the bottom end of the cyclone tank body 1. In addition, in specific applications, valves are arranged on the outer sides of the above-mentioned drainage pipe 6 and sewage pipe 7 (not shown in the figure, this is the prior art, and it will not be elaborated here), and a filtering mechanism 8 is arranged on the inner bottom end of the cyclone tank body 1; a filter plate 101 connected to the top of the drainage pipe 6 is embedded in the middle of the bottom end of the cyclone tank body 1.

[0026] With the aid of the above-mentioned technical scheme of the utility model, the structure of the utility model is reasonable and reliable. The sewage is injected into the cyclone tank body 1 through the water inlet pipe 5, so that the sewage can form a cyclone, thereby driving the feeding mechanism 4 to evenly add the coagulant. The suspended matter is collected by cooperating with the filtering mechanism 8 under the action of the cyclone. There is no need to provide a separate motor equipment to stir the sewage, thereby reducing energy consumption and operating costs.

[0027] In one embodiment, for the above-mentioned feeding mechanism 4, the feeding mechanism 4 includes a feeding box 401 arranged at the top end of the cover plate 3, and a feeding tube 402 penetrating the cover plate 3 is arranged at the bottom end of the feeding box 401, and a rotating rod 403 is arranged inside the feeding tube 402; the top end of the rotating rod 403 is movably connected to the internal top end of the feeding box 401. In addition, in specific applications, the top end of the above-mentioned rotating rod 403 is connected to the internal top end of the feeding box 401 through a bearing, and a spiral plate 4031 is arranged on the outer top of the rotating rod 403, and the outer side of the rotating rod 403 and located at the spiral plate A plurality of extension rods 4032 are arranged below the rotating plate 4031, and an auxiliary plate 4033 is arranged at the bottom end of one end of the extension rod 4032; a scraper 4034 cooperating with the filter plate 101 is arranged at the bottom end of the rotating rod 403, thereby realizing the addition of the coagulant. During the sewage injection process, a vortex can be generated by the flow of sewage, thereby driving the auxiliary plate 4033 and the rotating rod 403 to move, and then under the action of the spiral plate 4031, the coagulant inside the feed box 401 is evenly added to the vortex tank body 1 to mix with the sewage and form a suspended matter.

[0028] The working principle of the feeding mechanism 4 is as follows: under the action of the sewage vortex, the auxiliary plate 4033 will be driven to move, and then the rotating rod 403 will be driven to rotate, so that under the action of the spiral plate 4031, the coagulant inside the feeding box 401 will be driven to fall evenly into the vortex tank body 1 through the discharge pipe 402 and mix with the sewage. Then the scraper 4034 can also clean the filter plate 101 to avoid blockage of the filter plate 101.

[0029] In one embodiment, for the above-mentioned filtering mechanism 8, the filtering mechanism 8 includes a screening barrel 801 arranged at the bottom end of the cyclone tank body 1, a filter barrel 802 is arranged at the top of the screening barrel 801, and the screening barrel 801 and the filter barrel 802 are fixedly connected; a plurality of discharge ports 8011 are arranged on the outside of the screening barrel 801, and the orientation of the plurality of discharge ports 8011 is clockwise; the cross-section of the filter barrel 802 is a conical structure, thereby realizing the filtration of suspended matter. During the sewage cyclone, the suspended matter generated will enter the outside of the filter barrel 802 through the discharge port 8011, thereby realizing the collection of the suspended matter.

[0030] The working principle of the filtering mechanism 8 is as follows: when suspended matter is formed, the suspended matter will be blocked by the screening cylinder 801, and then fall into the interior of the filter cylinder 802. Due to the swirling effect of the sewage, the suspended matter will rotate with the sewage, and then under the action of centrifugal force, the suspended matter will enter the outside of the filter cylinder 802 through the discharge port 8011, thereby collecting the suspended matter and facilitating subsequent processing.

[0031] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0032] In actual application, first, sewage is added to the cyclone tank body 1 through the water inlet pipe 5, and then after a certain capacity is added, the sewage will form a vortex inside the cyclone tank body 1 due to the addition of sewage, and then the feeding mechanism 4 will be driven, and then the coagulant will be evenly added to the cyclone tank body 1 and mixed with the sewage, and suspended matter will be generated. Then, under the action of the sewage cyclone, the suspended matter will sink and pass through the bottom of the filtering mechanism 8 and accumulate at the bottom of the cyclone tank body 1, and then the sewage will pass through the filter plate 101 and be discharged through the drain pipe 6, and continue the subsequent treatment. After the water treatment is completed, the suspended matter can be discharged through the sewage pipe 7 for treatment.

[0033] In summary, with the help of the above technical solution of the utility model, the utility model has a reasonable and reliable structure. The sewage is injected into the swirl tank body 1 through the water inlet pipe 5, so that the sewage can form a swirl, thereby driving the feeding mechanism 4 to uniformly add the coagulant, and the suspended matter is collected by cooperating with the filtering mechanism 8 under the action of the swirl, without providing a separate motor device to stir the sewage, thereby reducing energy consumption and operating costs. By setting the feeding mechanism 4, the addition of the coagulant is realized, and the swirl can be generated by the flow of sewage during the sewage injection process, thereby driving the auxiliary plate 4033 and the rotating rod 403 to move, and then under the action of the spiral plate 4031, the coagulant inside the feed box 401 is uniformly added to the swirl tank body 1 to mix with the sewage and form suspended matter. By setting the filtering mechanism 8, the filtration of the suspended matter is realized. In the process of sewage swirl, the generated suspended matter will enter the outside of the filter cylinder 802 through the discharge port 8011, thereby realizing the collection of the suspended matter.
