Description

Bicycle pedal water purification device

technical field

The invention relates to a novel water purification device, which belongs to the technical field of water purification equipment.

Background technique

With the rapid development of the domestic economy, it is accompanied by serious environmental pollution, especially the pollution of water resources, and my country is a country that is short of fresh water resources. The pollution of water resources involves a wide range of fields such as domestic sewage, factory wastewater and special sewage. Although we have corresponding treatment technologies in most fields, due to the limitations of workload and funds, water pollution control in rural areas and safe drinking of rural people are the most urgently needed solutions in China but few people are involved. When it comes to water, we do very little. Among the approximately 800 million rural population, about 300 million people still live in a harsh environment where safe drinking water cannot be guaranteed and domestic sewage cannot be effectively treated. Many rural schools cannot provide students with safe drinking water . This not only seriously affects the health of the rural population, especially school-age children and primary and middle school students, but also becomes one of the reasons for the upstream pollution of rivers, soil and crop pollution. In my country's rapid development, there are still many rural people living in remote areas who still live in poverty and severe living conditions. Making full use of cheap and economical technology to popularize drinking water in rural areas is an important problem that needs to be solved urgently.

This shows that it is of great significance to design a water purification device that can be used in rural life, especially in rural schools. Using this equipment, students can exercise while getting safe, clean and pure water.

In order to achieve the above object, the present invention adopts the following technical solutions.

A bicycle pedal type water purification device is characterized in that it includes a bicycle frame, a bicycle pedal, a sprocket, a chain, an input shaft of a centrifugal water pump, a pump body of a centrifugal water pump, an impeller, a bottom valve, a water inlet pipe, a top water injection tank, an intermediate storage Water tank, bottom water storage tank, water outlet pipe, pure water storage barrel, upper filter hole, lower filter hole; the bicycle pedal is connected with the sprocket, the bicycle pedal is connected with the input shaft of the centrifugal water pump through a chain, and the input shaft of the centrifugal water pump The shaft is connected with the impeller through a key, and the impeller is installed eccentrically in the pump body of the centrifugal water pump. The water inlet pipe is installed at the water outlet of the pump body of the centrifugal water pump. There is a filter hole between the water tank and the intermediate water storage tank, and there is a filter hole between the intermediate water storage tank and the bottom water storage tank. The filter hole is equipped with PP cotton filter core, non-woven fabric, activated carbon and silicate ion natural stone.

Compared with the prior art, the present invention has the following advantages: small size, compact structure, easy transportation and installation, small investment, low energy consumption, no need for motors, human-driven, environmentally friendly and convenient, wide range of adaptability to raw water, high efficiency, after treatment The water quality fully meets the safety standard. A PP cotton filter element is installed between the top water injection tank and the middle water storage tank to filter colloidal impurities, sludge, organic pollutant minerals and other impurities in the water to achieve preliminary filtration. The middle water storage tank and the bottom water storage tank are equipped with a composite material filter layer, which includes non-woven fabrics to filter solid impurities in the water; activated carbon and silicate ion natural stones to effectively absorb free chlorine and odors in the water and reduce water pollution. Alkaline substances can improve the taste, improve the cleanliness of water, and achieve the effect of secondary purification. The layers of the clean water tank are detachable, easy to maintain, and the filter material is low in cost and easy to replace. The water flowing out from the outlet pipe of the bottom water storage tank reaches the safety standard of drinking water.

The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

Detailed ways

In Fig. 1 and Fig. 2, a bicycle pedal type water purification device is characterized in that it includes a bicycle frame 1, a sprocket 2, a bicycle pedal 3, a chain 4, a water inlet pipe 5, a water outlet pipe 6, and a pure water storage bucket 7. Bottom valve 8, centrifugal water pump pump body 9, impeller 10, centrifugal water pump input shaft 11, bottom water storage tank 12, middle water storage tank 13, top water injection tank 14, upper filter hole 15 and lower filter hole 16; the bicycle pedal 3 is connected to the sprocket 2, the bicycle pedal 3 is connected to the input shaft 11 of the centrifugal water pump through a chain 4, the input shaft 11 of the centrifugal water pump is connected to the impeller 10 through a key, and the impeller 10 is eccentrically installed on the pump body 9 of the centrifugal water pump Inside, the water outlet of the centrifugal water pump body 9 is equipped with a water inlet pipe 5, and the centrifugal water pump body 9 is connected to the water inlet of the top water injection tank 14, and there is an upper filter between the top water injection tank 14 and the middle water storage tank 13. hole 15, there is a lower filter hole 16 between the middle water storage tank 13 and the bottom water storage tank 12, a PP cotton filter core is housed in the upper filter hole 15, and non-woven fabric, activated carbon and Silicate ionic natural stone.

When the person on the bicycle frame 1 drives the bicycle pedal 3 to rotate, the sprocket 2 starts to rotate, and the motion form is transmitted to the input shaft 11 of the centrifugal water pump through the chain 4, and the input shaft 11 of the centrifugal water pump drives the impeller 10 to rotate at a high speed, and the impeller 10 Drive the sewage between the blades to rotate together, and due to the effect of centrifugal force, the sewage is thrown from the center of the impeller 10 to the outer edge of the impeller. At the same time, a certain vacuum is formed at the center of the impeller 10 due to the liquid being thrown out, and the pressure Pa at the liquid surface is higher than that at the center of the impeller. Therefore, the sewage sucked into the bottom valve 8 enters the pump body 9 under the action of the pressure difference. Inside. The impeller 10 is constantly rotating, and the sewage is continuously sucked in and pressed out. The sewage that comes out by the centrifugal water pump body 9 flows into the top floor water injection tank through the water inlet pipe 5 . A PP cotton filter element is housed in the upper filter hole 15 between the top floor water injection tank 14 and the middle water storage tank 13, and is used for impurity such as colloidal impurity, sludge, organic pollution mineral matter in the filtered water, and realizes primary filtration.
