Background technique

China is a country with relatively poor water resources, and the per capita water resources are less than 2200m ³ . In the vast rural areas of our country, water resource shortage and waste coexist, water resource utilization efficiency is low, and environmental pollution is serious. From the perspective of ecological environment, groundwater is seriously overexploited, and domestic garbage is full of rivers, which makes the water flow capacity very poor, which is not convenient for water flow or flood discharge, and then makes every river in the countryside a smelly ditch, which brings a lot of damage to crop irrigation. come to have a big impact.

Agriculture is the foundation of the national economy, the guarantee for the sustainable development of China's economy and society, and plays a role that cannot be underestimated in the development of the national economy. And rural water resources are an important factor affecting agricultural development and promoting the construction of new countryside. But at present, there are serious pollution, shortage and waste of rural water resources in our country. Protecting the rural water environment and solving the shortage of rural water resources have always been the most urgent issues facing my country's new rural construction and sustainable agricultural development.

At present, the main problems of agricultural filters are: the filter device mostly adopts a single form of sand and gravel filtration in a single tank, resulting in poor filtration performance; moreover, manual backwash opening and closing valves are mostly used, and the technical level is low, even if it is fully automatic control. Using single-tank control technology and installing a single-layer filter element is prone to problems such as filter hole clogging and small-hole filter element tearing. It cannot perform high-quality and effective filtration of polluted water and work for a long time, which will affect agricultural irrigation and other operations.

The high-pressure water pump is connected to the upper end of the shell, the right end of the high-pressure water intake pipe is connected to the shell, the left end of the high-pressure water intake pipe is connected to the right side of the high-pressure water pump, the upper end of the high-pressure water supply pipe is connected to the left side of the high-pressure water pump, and the lower end of the high-pressure water supply pipe passes through the end The cover is connected with the sewage pipe, the sewage pipe is set inside the filter device, the suction nozzle is connected with the low-pressure pipe, the low-pressure pipe is evenly distributed on the sewage pipe along the thread line, the low-pressure pipe is equipped with a high-pressure nozzle, the high-pressure nozzle is connected with the high-pressure pipe, and the high-pressure pipe Set in the sewage pipe, the right end of the sewage pipe is connected with the reducer shaft, the right end of the reducer shaft is connected with the steering block fixed on the reducer frame, and the steering block is connected with the reducer; when the self-cleaning function is turned on, part of the filtered water After the high-pressure water intake pipe is pressurized by the high-pressure water pump, it is sent to the high-pressure pipe through the high-pressure water supply pipe, and finally the high-pressure nozzle is sprayed on the inner surface of the fine filter to wash away impurities, and the sewage pipe rotates under the drive of the reducer. After washing the fine filter for one week, the sewage mixed with impurities and dirt will flow into the sewage pipe through the suction nozzle and the low-pressure pipe, and finally be discharged through the shell and the electric control sewage port. separation while accelerating the flow rate and enhancing filtration quality.

Compared with the prior art, the present invention is characterized in that:

1. Double-layer filtration with coarse and fine filter screens of different lengths effectively improves the filtration quality compared with a single-layer filter screen: first use the coarse filter screen to filter large particles of impurities such as gravel, and then use the small filter screen to filter Algae and other small impurities are filtered, and the water flow is controlled by setting different lengths of the coarse and fine filters, which can prevent the fine filter from clogging and improve the filtration quality to a certain extent;

2. There is a self-cleaning device in the filter, which can not only prolong the working time of the filter, but also solve the problem of filter deformation and damage caused by uneven pressure caused by filter blockage: the filtered clean water is passed through a high-pressure water pump Pressurize, and then the fine filter is sprayed by the high-pressure nozzle, and at the same time, the sewage pipe is rotating, and the impurities on the fine filter are evenly distributed on the sewage pipe along the thread line, through the high-pressure water jet in the high-pressure nozzle and the cleaning of the suction nozzle. Under the action, it collects into the sewage pipe along the low-pressure pipe, and the cleaning area can cover the fine filter, and finally realize the self-cleaning function of the fine filter. At the same time, by controlling the high-pressure water pump, the flow rate of high-pressure water is controlled, and by controlling the rotational movement of the sewage pipe to adjust the centrifugal force after the impurities are separated, different types of impurities are removed. At the same time, the pressure in the filter can be displayed by the pressure gauge, and the water pressure in the filter can be controlled by the electric control box to prevent the filter from being damaged;

3. Arrange the coarse and fine filters coaxially to save space and facilitate installation and transportation; at the same time, the coarse and fine filters and suction nozzles in the filter are detachable parts, which are convenient for cleaning and replacement at leisure.
