Description

An automatic rotary mine water pump screen

technical field

The invention relates to an automatic rotating mine water pump filter screen and a manufacturing method thereof, belonging to the technical field of water pump improvement.

Background technique

There are many types of filter screens, whether it is on the sprayer or on the drinking water pipeline, the filter screen will be used for pumping or draining water. Different environments require different models and different materials. The filter screen required at the water inlet of the mine water pump has special requirements, such as acid resistance, alkali resistance, temperature resistance, and wear resistance; nylon Oil filters can be used in air conditioners, range hoods, washing machines, car engine systems, fuel tanks, fans, sinks, water pumps, vacuum cleaners, compressors, water purifiers, filters, excavators, but not in mines, municipal sewage, mud Algal land pumping, industrial wastewater pumping, etc. Although it is suitable for different environments, it is limited by bottlenecks in this environment. For example, it is easy to block when it is used in heavy industry or urban sewage pumping, resulting in unnecessary power loss. Of course, the current submersible pump can solve some of the problems that are easy to block, but if it is long-distance pumping, it is not only a problem of high energy consumption, but also a problem of high investment costs. For example, the length of the cable needs to be increased, which is not conducive to The management of the water pump requires relatively high acid and alkali resistance of the water pump, and there will still be problems of blockage. At present, the simplest and most direct solution is to use a wooden stick or a hook to brush away or scrape off the debris, but it is inconvenient. At present, the most favorable ones for the pumping and drainage of mines and other sewage are the Yuyao Haoji filter, the filter hole at the bottom of the submersible pump, and the filter hole in the middle of the submersible pump. The problem.

detailed description

The rated voltage of the micro-motor is assembled with different models according to the needs of the environment, which is lower than the underground safety voltage. , the inlet wire of the micro motor passes through the connection between the water inlet pipe and the sealed box, the outer inlet wire is fixed on the water inlet pipe and reaches the water pump along the water inlet pipe, and a DC charger is installed near the installation place of the water pump. The charger is anti-corrosion and explosion-proof The function of the micro-motor is used when the water pump is just started or when the speed of the Mitsubishi column is very slow. It is not often turned on and the load is small, so it saves energy.

Because there is negative pressure at the water inlet inside the filter screen, the water outside the filter screen must pass through the water channel of the shell at the Mitsubishi column. Due to the kinetic energy of the water, the Mitsubishi columnar blade will rotate, and the lower end of the Mitsubishi column and the blade will be in contact with the shell. There is a mechanical connection at the lower end of the blade, which can rotate around the round hole at the lower end of the shell. The gear at the upper end of the Mitsubishi columnar blade meshes with the intermediate gear to realize transmission. The Mitsubishi column is directional rotation, which can improve stability.

The outer teeth of the intermediate gear are meshed with the first gear of the Mitsubishi column, the inner teeth are meshed with the second gear of the micromotor, and the metal ring is connected with the intermediate gear so as to be transmitted to the metal short pipe with a scraper bar.

The entire water inlet pipe passes through the sealing box, and the connection is sealed by welding technology, and the end is welded to the upper part of the filter net. The specific diameter depends on the size of the water inlet pipe.

Depending on the type of water pump, the bottom of the filter determines whether to fix a small cylinder. For dry water pumps, since there are no parts installed at the bottom of the filter, a small cylinder at the bottom can make the scraper more stable. The same bottom filter hole is submerged The same is true for the pump; there is only a submersible pump with a filter screen hole in the middle. Because the lower part of the filter screen needs to install parts, it is not easy to install a small cylinder. Of course, it has little effect on the stability of the scraper rod.

The shell is very critical. The middle part is equipped with a water channel, which is beneficial to the entry of water and the protection of the directional Mitsubishi column. A large hole is left at the bottom, and the aperture is slightly larger than the diameter of the bottom of the filter screen, which is conducive to slag discharge; Columns are pin links.

When working: Under the kinetic energy of water, the directional Mitsubishi column starts to rotate, the intermediate gear rotates under the action of the micro motor and the directional Mitsubishi column, and at the same time the intermediate gear rotates with the short metal tube and the scraper rod, and the scraper rod scrapes off the dust on the filter screen. Blockage, the upper part of the filter screen is welded to the water inlet pipe, and the bottom part is connected to the scraper rod.

performance analysis

The filter screen device can be scaled into different models through different proportions, suitable for use by large, medium and small enterprises. All parts of the device are modular design, the parts are detachable, easy to transport, easy to assemble, convenient, fast and safe , The pumping efficiency is high, which saves a lot of expenses for the enterprise. The test shows that when the filter device is not used at the inlet end of the water pump, the change of the resistance drop of the water pipe inlet with time is shown in curve 1 in Figure 2; the filter device is installed Finally, the curve of the water pipe inlet resistance drop with time is the curve 2 in Figure 2. It can be seen from this that the resistance drop is greater than the traditional rate net device at the beginning, and the system resistance drop stabilizes after a period of time, thereby improving the stability of the entire system , reducing useless work.
