Description

[Detailed Description of the Invention] Conventionally, garbage has been filtered using a dual strainer-1 self-cleaning strainer, a cyclone, a filtration device, etc. in the pressure feed pipe after pumping (after-treatment). , debris trapped in rotating parts such as pumps and self-cleaning strainers,
In addition, clogging of the filter with debris causes a shortage of cooling water, which often causes the pump to be unable to pump up water due to an emergency stop of the prime mover, and there are many problems with the discharge of debris outside the pipe, maintenance, etc.

The present invention is a filtration type water absorption tank for the purpose of filtering and absorbing water for a pump in order to eliminate the above-mentioned prohibition of post-treatment by filtering waste before pumping water (pre-treatment).

The amount of cooling water in conventional lifting and drainage pump stations is that the secondary cooling water that cools the secondary cooling water (cooling water for engines, motors, reducers, etc.) is approximately twice the amount of secondary cooling water, and therefore a large amount of cooling is required. needed water.

The present applicant had previously proposed a "flowing water tube type cooler" in a patent application dated March 1, 1978 (Patent Application No. 022542 of 1972). Since cooling water is no longer needed and the amount of water supplied is drastically reduced even at a pumping station with a large diameter pump, the purpose of water supply can be fully achieved with a filtration type water suction tank.

Next, an embodiment of the present invention will be explained. First, FIG.
Referring to FIG. 2, a filtration part (■) having the same bottom plate as the bottom plate of the water absorption tank (2) is provided on the lower outer periphery of the filtration type water absorption tank (2) according to the present invention, and the outer cylinder (2) of the filtration part is equidistant from the inner cylinder (2) on the circumference. Inner cylinder ■ and outer cylinder ■ with multiple ribs [phase] welded to the upper part to make it
The filtration surface is perforated and made of stainless steel plate to prevent the filtration holes from becoming infarcted by rust.

The filtration section ■ is filled with filter material ■, and the upper part is filled with filter material ■
A slightly thicker ring-shaped rubber plate is placed on top of the ring-shaped rubber plate to prevent it from being washed away, and a pressing plate made of ring-shaped steel plates cut into multiple pieces ■ and multiple pressing device metal fittings ■ are used to press the rubber plate. .

The pressing plate (■) is provided with multiple seats into which the lower part of the pressing device metal fittings are inserted.

Figures 3 and 4 are detailed views of the pressing device metal fitting ■ and the flange tightening part. At the bottom, fit the spring 0 into the concave part of the pressing plate (2), tighten the adjustment nut (2), and fix it by the tension of the spring (2).

A washer [phase] was provided to facilitate tightening of the adjustment nut ■.

The location where the filtration type water suction tank of the present invention is installed is the inlet of the main pump water suction tank, inside the screen, and the inflow flow rate is quite fast (0,5- to o, 5-A). Since the filtration rate can be freely designed with respect to the filtration area, the filtration efficiency can be increased by designing the filtration rate to be smaller than the inflow rate (external flow rate) and completely eliminate the adsorption power for dirt.

In addition, if the filter media is clogged with scale, backwashing can be performed by backflowing from the elevated water tank.

In addition, when the filter material needs to be replaced or cleaned, it can be carried out freely.

Fig. 5 shows a conventional embodiment, which is a cooling water (circulation) system diagram, and Fig. 6 shows a patent application filed by the present applicant on March 1, 1978 (Patent Application No. 022542 of 1978). It is a system diagram of a self-cooling, self-sufficient cooling water system that uses a running water tube type cooler @ and the filtration type water absorption tank of the present invention, which was proposed by the authors.

A comparative explanation will be given of parts related to the present invention.

In Figure 5, a well (■) is drilled and water is pumped up to the elevated water tank 0 using an intake pump [phase].The intake pump (■) is a deep well with a high head and a large power capacity.

Also, depending on the water quality, if there is a high iron content, an iron removal device will be required, and if there is a lot of sand, a sand removal device will be required.

In comparison, in Figure 6, the filtration type water intake tank ■ takes water from the water intake tank of the main pump [phase], so the lift of the water intake pump [phase] is low, and therefore the power capacity is also very small. When using water, it is possible to easily dispense chemicals in conjunction with the water intake pump [phase], and in the case of the water supply shown in Figure 5, the circulating water is cooled by the cooler [phase], so the secondary cooling water is A pump [phase] is required, and the amount of water supplied increases by the amount of water sealed by the secondary cooling water pump [phase].

In the future, new pumping stations will no longer be able to rely on tap water or well water, and will have to use raw water.

Each local government spends a large amount of money on raw water treatment facilities, but by minimizing the amount of water supplied, it becomes possible to effectively use filtering water absorption tanks, which not only saves a large amount of money, but also saves electricity and water. becomes.

It will be effective for the water supply of pumping stations in the future, and will make a large contribution.
