Detailed ways

The utility model will be further described below in combination with specific embodiments, so as to better understand the technical solution of the utility model.

Embodiment 1: A kind of automatic car washing sewage treatment equipment, referring to Fig. 1, comprises negative pressure tank 3, siphon well 4 and sludge hoist 7 that are arranged in the sewage tank, and purifying element 2 is housed in described negative pressure tank 3, Sewage inlet 1 is set on the side of the lower part of the negative pressure tank, and sewage outlet 6 is set on the bottom. The sludge lifting pipeline 11, the sludge lifting machine 7 is arranged on the top of the sludge lifting pipeline 11, and the sludge discharge port 8 is arranged on the side of the top of the sludge lifting pipeline, and the upper part of the negative pressure tank is provided with a clean water outlet, and the clean water outlet The inlet of the siphon well 4 is connected through the water pipeline, and a water pump 5 is installed at the outlet of the top of the siphon well 4, and the outlet of the water pump 5 is connected to the recovery tank 10, and a water replenishment port is also arranged on the top of the siphon well 4, and a raw water recoil valve 9 is installed at the water replenishment port . The raw water recoil valve 9 is connected to the raw water supply source through a pipeline.

As shown in Figure 1, in this embodiment, the two ends of the negative pressure tank 3 gradually reduce in diameter from the tank body to the mouth of the tank, forming a tapered structure, the middle part of the tank body is a columnar body, and the purification element 2 is located in the columnar body part. Therefore, the sewage outlet located at the bottom of the negative pressure tank and the water outlet located at the upper part of the negative pressure tank have smaller apertures than the tank body, and the sewage outlet aperture is smaller than the tank body, which can form sufficient pressure at the sewage outlet after the sewage sludge settles. Easy to discharge. And the aperture of the clean water port is smaller than the tank body, which is convenient for the filtered clean water to discharge. The sewage inlet of the negative pressure tank is set at the lower part of the water purification outlet, mainly to ensure that the sewage is in a bottom-up circulation form during the purification process. The purification element 2 includes filter screens 21 arranged horizontally in the tank and arranged intermittently and equidistantly, and U-shaped arms 22 connecting the lateral ends of each filter screen, so that the overall purification element is arranged in an "S" shape as shown in Figure 1. The bottom walls of each U-shaped arm are arranged in a straight line, and the side walls of the U-shaped arms are perpendicular to the bottom wall. The structural form of the purification element, because the filter wall is vertical, and the sewage goes from bottom to top, the sewage impurities can quickly fall along the vertical filter wall under the action of its own gravity, and will not deposit on the filter wall. The filter screen is arranged intermittently and equidistantly. After being separated by U-shaped arms, multiple filter channels can be formed to disperse the sewage and reduce the load on the filter screen. Compared with the filtration form of the entire filter screen, the filtration is more uniform. , fine, and can effectively extend the service life of the filter.

The working process of this embodiment is as follows: The whole set of automatic car washing sewage treatment equipment in this embodiment is firmly installed in the sewage pool, the sewage in the pool enters the negative pressure tank from the sewage inlet, flows from bottom to top, and after being filtered by the purification element, the clean water flows from The upper end of the negative pressure tank is discharged into the siphon well, pumped out by the water pump, and flowed into the recovery pool for reuse. The sludge settles at the sewage outlet of the negative pressure tank under the action of its own gravity. When it accumulates to a certain extent, the sludge elevator works to extract the sludge from the sewage outlet, pump it from bottom to top to the upper part, and lift it through the sludge. The sludge discharge port on the pipeline is discharged. While the sludge elevator is working, open the raw water recoil valve, and the raw water will flow back to the purification element under the action of the negative pressure of the siphon well and the power of the sludge elevator, and backwash the filter screen of the purification element. Therefore, the purification components in this embodiment hardly need to be replaced, and regular cleaning can be realized by using its own energy. The sewage in this embodiment can be reused, and the conversion rate of sewage is high. The purification is mainly completed by its own power, and all energy sources are used mutually to realize Maximum energy saving and environmental protection.
