Embodiment 1

[0054] see Figure 1-3 , a pretreatment device for sewage, comprising:

[0055] The treatment tank 1 has an accommodating cavity inside, which can accommodate the sewage to be treated; Empty pipe 9, the inside of the vent pipe 9 is provided with a vent valve 10, the vent valve 10 is used to control the on-off of the vent pipe 9, when the vent pipe 9 is in the passage, the sewage in the treatment tank 1 can pass through the vent pipe 9 discharge, when the vent pipe 9 was in open circuit, the sewage in the treatment tank 1 could not be discharged.

[0056] The water inlet pipe 2 is provided with a water inlet valve 3 inside the water inlet pipe 2. The water inlet valve 3 is used to control the on-off of the water inlet pipe 2. When the water inlet pipe 2 is in the passage, water can be added to the treatment tank 1, otherwise it cannot be added. The bottom end of the water inlet pipe 2 has a first branch pipe 4 and a second branch pipe 5, and the first branch pipe 4 and the se...

Embodiment 2

[0063] see figure 2 and image 3 , on the basis of Embodiment 1, the inner top wall of the treatment tank 1 is relatively fixedly installed with a first water retaining plate 14 and a second water retaining plate 15, and the first water retaining plate 14 and the second water retaining plate 15 are respectively located at The rear and front of the sampling pipe 11, the sampling pipe 11 is located between the first water retaining plate 14 and the second water retaining plate 15;

[0064] The end of the first branch pipe 4 is bent and positioned behind the first water retaining plate 14, and the end of the second branch pipe 5 is bent and positioned in front of the second water retaining plate 15. When the first branch pipe 4 and the second branch pipe 5 are out of water , sewage can generate eddy currents in the treatment tank 1 under the guidance of the first water retaining plate 14 and the second water retaining plate 15, the first water retaining plate 14 and the second ...

Embodiment 3

[0067] see Figure 4-8 , on the basis of Embodiment 1 and Embodiment 2, the inner wall of the settling bucket 8 is fixedly equipped with a fixed ring 17, the inner wall of the fixed ring 17 is fixedly installed with a fixed plate 18, and the outer wall of the fixed plate 18 is evenly provided with settling holes 21, and the sedimentation Hole 21 makes the sundries in sewage can move from the top of fixed disc 18 to the below of fixed disc 18, and the cutting assembly that is arranged on the fixed disc 18 is used to rotate under the effect of eddy current and remove the sundries below fixed disc 18. things to cut;

[0068] Cutting assembly comprises rotating column 19, blade 20, rotating shaft 22 and cutting blade 23, and rotating column 19 rotation is arranged on the center of fixed plate 18 tops, and the outer wall of rotating column 19 is evenly fixedly equipped with blade 20, and the section plane of blade 20 is "J" shape is convenient to be promoted and rotated by the wat...

Abstract

The invention relates to the technical field of sewage treatment, and discloses a sewage pretreatment device, which comprises a treatment tank, which is internally provided with an accommodating cavity for accommodating sewage to be treated; a precipitation hopper is fixedly mounted on the inner wall of the treatment tank and is used for sealing the bottom of the treatment tank; a first branch pipe and a second branch pipe are arranged at the bottom end of the water inlet pipe, and the first branch pipe and the second branch pipe are fixedly mounted on the left side and the right side of the treatment tank respectively and extend into the treatment tank. Sewage flowing out of the first branch pipe and the second branch pipe is divided into two paths to flow into the treatment tank, the two paths of sewage flow around the first water baffle and the second water baffle in a vortex form under the blocking of the first water baffle and the second water baffle, and the vortex flow state of the sewage can be further enhanced through guide threads formed in the outer walls of the first water baffle and the second water baffle. The sewage scrolls in a vortex manner, so that the precipitation of impurities in the sewage can be accelerated, and the time for waiting for sewage precipitation is shorter.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a pretreatment device for sewage. Background technique [0002] With the development of society and the advancement of science and technology, the sewage treatment industry is gradually becoming intelligent. Smart water services are increasingly relying on online monitoring systems for water quality. Therefore, the stability of online monitoring systems has gradually become the focus of smart water services. The water quality analysis instrument in the online monitoring system is often equipped with a simple screen and a pretreatment box. The box is equipped with agitator, solenoid valve and other equipment. The small tube is finally drawn into the instrument for detection. In the prior art, since the water samples to be tested are relatively clean after being treated by the sewage plant, the use of this simple pretreatment device can meet the pretreatment requirements ...
