With the scarcity of water resources in our country, water conservation has become a top priority. However, the washing water produced by household water can be simply recycled as a reclaimed water for urinating, watering flowers and scrubbing articles. How to increase the pressure of cleaned water because of no pressure? The hydraulic pressure has become a problem, "step on the pump" is developed to meet this requirement, this article describes the "step on the pump" structure, working principle and characteristics, and use the foot as a motivation to pressure water without pressure for Reclaimed water and other water use, to provide users with very convenient conditions. About two-thirds of urban residents consume domestic water for washing, showering, washing (collectively referred to as washing water), and wet-flushing. Washing water is discharged only by mild pollution. If the household recycles this part of the water for its own use, it will greatly ease the shortage of urban water resources and will also reduce the water charges for the households. According to the shortage of water resources in most parts of China and the existence of land for sewage treatment, management and funding, it is bound to be of great significance to study and solve the problem of household water-saving wash water reuse. China's urban residents commonly used sanitary ware has a sink, washbasin and squatting (or sitting) toilet. There are 500mm ~ 600mm high space below the wash basin and washbasin. Collecting and storing the container together with the collected water for collection does not cause any problem. Washing water pollution is small, can be precipitated, sieve filter, under conditions where necessary and households dosing bleach disinfection or the use of commercially available micro-ozone generator for ozone disinfection, you can get purified water for the toilet Rinse, watering flowers, rinse dirt and so on. "Step on pump" development "Step on pump" structure Clean water purification and reuse technology should be based on ①households do not affect each other, and the building has nothing to do with the water supply and drainage. ② simple purification of washing water ③ easy to reuse washing water ④ the use of existing conditions slightly modified households ⑤ low cost ⑥ significant cost savings festival. One of the key equipment is to develop a pressurized water delivery device that is "step on the pump" [1]. "Step on pump" is made of elastic rubber material, which consists of a foot supercharger and an energy storage device. Foot pedal when placed on an approximate diameter of about 150mm ~ 200mm, at the entrance of the interior with a back plate to prevent the foot when the supercharger water back to the inlet pipe, foot pedal supercharger outlet connected storage Device. The energy storage device is oblong with the approximate diameter of about 50mm-100mm and the length of 100-150mm. The inlet of the energy storage device is provided with a check-back plate to prevent the water in the energy storage device from flowing back to the supercharger and the outlet of the energy storage device. Water pipe connection. "Step on the pump" shown in Figure 1. Work process "Step on pump" import and export, respectively, with the washing water purification container outlet and water pipes connected, even into the container after the water can flow into the supercharger, the supercharger bulging, step on foot to pedal Turbocharger, supercharger inlet check board at the same time off, the turbocharger water into pressure water, into the energy storage device and then into the water pipe. When the foot is stopped, the energy storage inside check plate is closed, the supercharger inlet inner check plate is opened, and the purified water inside the container flows into the supercharger again. The water pressure in the container is sent to the accumulator and water pipe. The purpose of setting the energy storage tank is filled with water. In design, the volume of the turbocharger is 3 ~ 4 times the volume of the accumulator water pipe. Even if the pedal stops the gap of the foot, Water flow to the water pipe. "Step on the pump," the use of the characteristics of foot force, force convenient, without electricity, you can make low pressure sent to a high place. "Step on pump" pressure "step pump" is based on the principle of piston pump made. According to Bernoulli's equation, P1 / r = Z2 + U22 / 2g is obtained without considering the "stepping pump" and head loss of the water pipe when the supercharger is full of water, and when the head U22 / 2g is 1 ~ 2m, Z2 is "stepping on the pump" to the toilet tank 2.10m, P1 / r = 3.1m ~ 4.1m, this pressure value supercharger is easy to do. Application Example Example 1 Set in a household washbasin set 400mm long and 300mm wide and 600mm high and set collection precipitation, screening, filtration, water storage containers. The container can be made of steel or glass, etc., the container is provided with overflow pipe, drain pipe, outlet pipe. Out of water pipes and water pipes are used 3/8 "hose and" step on pump "connected to the water pipe end of the outlet leading to the toilet (high or low) tank, according to the use of the method with the foot pedal so that the pressure inside the container Water into the tank, to be used for flushing Example 2 A household hot water placed in a plastic bucket, with a "step on the pump" were connected with the barrel and the tube with a shower head, according to the foot supercharger for steaming (1) Rubber "step pump" can rely on the foot to send water from low to high, for toilet flushing, watering, showering, washing items, etc. (2) "step on pump" does not require other power , Has a variety of uses, such as workers in construction sites summer cold water bathing. (3) "step pump" durable, easy to damage, easy to operate. (4) "pump" manufacturing costs about 30 yuan, the price is low.
