Problems solved by technology

When coagulating and clarifying sewage containing large particles of impurities such as sediment, these large particles of impurities will not participate in the coagulation reaction, but will consume a large amount of coagulation agents, resulting in a large waste of coagulation agents. Therefore, before coagulation and clarification Generally, sewage filtration is required to remove large particles of impurities in sewage
General coagulation devices do not have filtering function, and an additional independent filtering structure is required
In addition, the existing coagulation and clarification devices generally use mixing and stirring devices for mixing sewage and chemicals. The existing mixing and stirring devices generally use motors to drive stirring blades to stir the liquid for mixing. Water treatment generally needs to be carried out continuously, so motors are required to continuously Drive the stirring blades to rotate, so more energy is consumed

Embodiment 1

[0038] Example 1, such as Figure 1-3 As shown, the swirl mixing solid-liquid separator 100 includes a water inlet pipe 110, a swirl generating container 130 and an outlet pipe 120. The swirl generating container 130 is a cylindrical container whose inner wall is arranged along a spiral line, and the water inlet pipe 110 is a square The pipe is arranged along the tangential direction of the side wall of the swirl flow generating container 130 . The water outlet 131 of the swirl flow generating container 130 is located on the bottom wall thereof and the center line of the water outlet 131 is coaxial with the side wall of the swirl flow generating container 130 . The water outlet pipe 120 is a vertical circular pipe. An impeller 140 is arranged in the water outlet pipe 120. A support is fixedly arranged in the water outlet pipe 120. The rotating shaft of the impeller 140 is connected to the support in rotation. The lower half of the pipe wall of the water outlet pipe 120 is uni...

Embodiment 2

[0039] Embodiment 2: The difference with Embodiment 1 is that, as Figure 4 and Figure 5 As shown, there is no impeller 140 in the cyclone mixing solid-liquid separator 100 , and a protrusion 150 is provided on the side wall of the cyclone generating container 130 . The protrusions 150 are sheet-shaped, and there are multiple protrusions 150 arranged along the circumferential direction of the side wall of the swirl flow generating container 130 . The protrusion 150 can be formed by directly fixing the protrusion on the side wall of the swirl flow generating container 130, or can be grooved on the side wall of the swirl flow generating container 130, and formed by a relatively convex part between two adjacent grooves, It can also be formed by bending the side wall, or using two or more of the above three methods at the same time. The protrusion 150 in this embodiment is formed by directly fixing the protrusion on the side wall of the swirl flow generating container 130 form....

Embodiment 3

[0040] Embodiment 3: The difference with Embodiment 1 is that, as Figure 6 As shown, a dispersing funnel 190 is arranged in the water outlet pipe 120 , and a sealing plate 170 and a collecting pipe 171 are arranged on the top of the sedimentation funnel 160 . The water outlet 131 on the water outlet pipe 120 is arranged at the bottom of the water outlet pipe 120 , the water outlet pipe 120 is rectangular, and there are multiple outlets along the circumference of the water outlet pipe 120 , and no water outlet hole 161 is provided on the settling bucket 160 .

Abstract

In order to solve the technical problem that an independent filtering device needs to be arranged in the prior art, the rotational flow mixed type solid-liquid separator and the rotational flow mixed type coagulation clarification device are provided, the rotational flow mixed type solid-liquid separator comprises a water inlet pipe, a rotational flow generation container and a water outlet pipe, and the rotational flow generation container is provided with an inlet and an outlet; a water outlet is formed in the pipe wall of the water outlet pipe, and an opening in the lower end of the water outlet pipe is a sand outlet; an impeller is rotationally connected in the rotational flow generation container; the rotational flow mixing type coagulation clarification device comprises a coagulation clarification cylinder and the rotational flow mixing type solid-liquid separator, a clear water area, a mixing area and a sludge settling area are sequentially arranged in the coagulation clarification cylinder from top to bottom, stirring filler is arranged in the mixing area, a water outlet of the solid-liquid separator is communicated with the coagulation clarification cylinder, and a water outlet of the solid-liquid separator is communicated with the sludge settling area. A clean water pipe communicated with the clean water area is arranged on the coagulation clarification cylinder; according to the invention, liquid mixing is more uniform, and heavy impurities such as silt can be separated from water flow along with rotational flow.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to a cyclone mixing type solid-liquid separator and a cyclone mixing type coagulation and clarification device. Background technique [0002] During sewage treatment, coagulation and clarification methods are often used to remove colloids and finely suspended aggregates in wastewater, and coagulants are used to aggregate and precipitate colloidal particles and finely suspended matter in water. When coagulating and clarifying sewage containing large particles of impurities such as sediment, these large particles of impurities will not participate in the coagulation reaction, but will consume a large amount of coagulation agents, resulting in a large waste of coagulation agents. Therefore, before coagulation and clarification Generally, sewage filtration is required to remove large particles of impurities in sewage. General coagulation devices do not have a filtering function, and an addi...
