Description

Multi-stage sewage recovery and filtration device

technical field

The utility model relates to the field of water treatment equipment, in particular to a multi-stage sewage recycling and filtering device.

Background technique

With the progress of society and the continuous development of industry and agriculture, the pollution brought by industrial and agricultural waste and the lag of environmental protection work to people's living environment is becoming more and more serious, especially the pollution brought to water which is closely related to people's life.

At present, the domestic water for urban and rural residents is mainly directly supplied by the water supply company through the water supply pipeline. Due to the old water supply pipeline, it is easy to cause secondary pollution of water during the transportation process, which directly affects the water quality and affects people's lives. big impact. For this reason, many water treatment devices have appeared on the market. Due to the long-term use of the current water treatment devices, some dirt in the water is trapped in the water seepage channel on the outer surface of the filter element. If it is not cleaned for a long time, it will easily cause the seepage channel to be blocked; Therefore, the filter element should be cleaned, but the existing water treatment device needs to disassemble the filter element for cleaning, and it is often necessary to wait for the filter element to be blocked seriously before cleaning. Damage to the filter element shortens the service life of the water treatment device. At the same time, the existing water treatment device needs to add water frequently, and cannot use non-drinking water and water for washing at the same time, which is very inconvenient to use.

Pneumatic valves are provided at the bottom of the filter barrel and the fine filter barrel, and one end of the connecting pipe is connected to the bottom of the barrel of the primary filter barrel, and the other end is connected to the upper part of the barrel of the fine filter barrel.

Among them, the filter material is made of a variety of materials, including coconut shell activated carbon layer, fiber layer and microporous filtration membrane, and the filtration process ratio of coconut shell activated carbon layer, fiber layer and microporous filtration membrane is 20-15:10- 8:1.

Among them, one end of the sewage pipe is arranged on the barrel body of the upper part of the filter material, and the other end is set on the barrel body of the lower part of the filter material, and the upper and lower interfaces are provided with independent sewage valves.

Preferably, the sewage inlet of the primary filter barrel is provided with a cage filter, and the filter aperture of the cage filter is 20-50 mesh.

The utility model has the following beneficial effects:

1. The utility model uses a composite filter material for sewage treatment through structural optimization design, and develops a filter material structure with a suitable filtration process ratio for the type of sewage. The selected filter material can be regenerated by reverse cleaning. Improve the utilization rate of filter material.

2. The rationally designed multi-stage sewage recovery and filtration device can add a cage filter at the primary filter barrel, which expands the range of sewage that can be filtered, and has a better filtering effect on solid dirt in sewage.

detailed description

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments.

As shown in Figure 1, the utility model discloses a multi-stage sewage recovery and filtration device, including a primary filter barrel 1, a fine filter barrel 2, a filter material, a sewage pipe 6, a pneumatic valve 8, a connecting pipe 9 and a cage filter 10. The structure of the primary filter barrel 1 and the fine filter barrel 2 is the same. Both the primary filter barrel 1 and the fine filter barrel 2 are provided with filter materials. The distance between the filter material and the bottom of the recovery barrel is 15-30 cm. The filter barrel 1 is connected with the fine filter barrel 2, one end of the sewage pipe 6 is set on the barrel body of the upper part of the filter material, and the other end is set on the barrel body of the lower part of the filter material, and the upper and lower interfaces are set There is an independent sewage valve 7, the bottom of the primary filter barrel 1 and the fine filter barrel 2 are provided with a pneumatic valve 8, one end of the connecting pipe 9 is connected to the bottom of the primary filter barrel 1, and the other end is connected to the upper part of the fine filter barrel 2.

The filter material is composed of various materials, including coconut shell activated carbon layer 3, fiber layer 4 and microporous filtration membrane 5, and the filtration process ratio of coconut shell activated carbon layer 3, fiber layer 4 and microporous filtration membrane 5 is 20- 15:10-8:1.

working principle:

The multi-stage sewage recycling and filtering device of this application adopts the double-barrel design of the primary filter barrel 1 and the fine filter barrel 2, wherein the primary filter barrel 1 mainly filters out coarse substances, and the fine filter barrel 2 mainly filters out fine substances. The filtration process is, from The cage filter 10 of the primary filter tank 1 is filled with sewage to adjust the amount of sewage inflow, and the sewage is filtered and adsorbed through the filter material. The infiltrated water is relatively clean, but there are still small impurities. The water that has been filtered once is fed into the fine filter barrel 2 through the connecting pipe 9 and filtered again, and the water is clear and clean after two times of filtered water treatment; however, during the water filtration process, a large amount of pollutants adhere to the filter material and must be cleaned regularly; in order to ensure the continuity of the filter material use.

Filter material cleaning:

Cleaning is simple and fast using the principle of air pressure and air flotation:

First open the drain valve 7 to lower the water level, then open the high-pressure pneumatic valve 8, inject high-pressure air, use the air pressure flow to fully stir the inside of the barrel, and stir out the attached dirt originally attached to the filter material; flow out along the drain valve, and then Open the lower drain valve 7 to drain all the sewage in the barrel, and at the same time close the air pressure valve 8, close the lower drain valve 7, open the pneumatic valve 8, let the water level overflow the upper drain valve 7 again, close the pneumatic valve 8, and open the lower drain valve again 7. After draining the sewage in the barrel, close the upper and lower drain valves 7 to finish cleaning.

The above is only a preferred embodiment of the utility model, but the scope of protection of the utility model is not limited thereto, and any person familiar with the technical field can easily think of All changes or replacements should fall within the protection scope of the present utility model.
