Description

Detailed Description of the Invention "Field of Industrial Application" The present invention relates to a filtration device used in reservoir ponds, fishing ponds, swimming pools, public baths, etc., and in particular, the present invention relates to a filtration device for use in reservoir ponds, fishing ponds, swimming pools, public baths, etc. The present invention relates to a purification device for purifying water.

``Prior Art'' Traditionally, strainers used in reservoir ponds, fishing ponds, swimming pools, public baths, etc., are strainers that have a bag or the like installed separately from the pump to collect contaminated water pumped up by a pump. This strainer purifies the polluted water by removing gravel, dirt, scale, etc.

Furthermore, instead of providing an external strainer, a bag or the like is attached to the tip of a hose connected to the water outlet of the pump, and the strain is carried out using this bag.

If the bag becomes clogged after using it for a certain period of time and it becomes difficult to clean it,
Bags, etc. are removed from the ends of strainers, water hoses, etc., cleaned and reused, or used bags, etc. are discarded and replaced with new ones.

``Problems to be solved by the invention'' In conventional filtration equipment, the suction part for contaminated water and the filtration parts such as pumps, strainers, bags, etc. are separate parts, and these are connected with hoses, etc., so the entire filtration equipment is used. As the spatial volume occupied by
Connection, inspection, maintenance, etc. of these devices required a lot of time and effort.

In addition, cleaning bags, etc. not only takes time, but also bothers workers as they directly dispose of waste.
Disposable bags were expensive, and high-quality ones did not exist.

Furthermore, if the bag becomes clogged after being used for a certain period of time, it becomes difficult for water to pass through the bag, etc., increasing the pressure applied to the bag, etc., which may cause part of the bag to tear or the connection to come loose. I had something to do.

"Means and effects for solving the problems" The present invention has been made in view of the above-mentioned problems. It consists of a connecting part and a bending part that can be removed from the cylinder, and by screwing this part directly onto the pump, the volume occupied by the pump can be reduced, and the entire pump can be submerged in water, allowing only external power to be supplied. It was designed to be supplied.

In addition, when cleaning the drain section, since the drain section is a cloth held between two wire meshes, water can be flowed in the opposite direction to remove clogging, etc. Furthermore, the connecting section and bending section are cylindrical. Since it can be removed from the overtube, it can be used even if thorough cleaning is required after long-term use.

Furthermore, the connecting part and bending part of the overtube are firmly attached to the overtube by flanges and bolts, and these are sandwiched between two pieces of wire mesh, and the threads cut into the pipe at the connection part. Because it is screwed onto the pump at some points, the pump can be used with confidence because the cloth will not tear or the connection will come off even if the cloth becomes clogged and the pressure is quite high. .

In addition, high-priced, high-quality cloth can be used for an extremely long period of time, making full use of its performance.

"Example" FIG. 1 is a perspective view of a tube used in the tube device according to the present invention, and FIG. 2 is an end view cut along the line A-A in FIG. 1, where 4 is a tube, and 5 is an outer wire mesh. , 6 is an inner wire mesh, and 7 is a cloth.

As shown in FIG. 2, the overtube 4 is constructed such that a cloth 7 is sandwiched between two wire meshes, an outer wire mesh 5 and an inner wire mesh 6. Both ends 4a of the overtube 4
and 4a' are fixed to flanges 8 and 8', respectively, by welding or adhesive.

Here, the overtube 4 uses a cylindrical body in which a cloth 7 is sandwiched between two outer wire meshes 5 and an inner wire mesh 6, and this cylindrical body is formed to a certain length and then cut. It is.

By preparing overtubes 4 having different lengths, it is possible to use the overtube 4 with the most suitable length depending on the size of the place of use, degree of dirt, etc.

FIG. 3 is a front view showing the cover part, 2 is the cover part, 9 is the connecting part, and 10 is the bent part.

The cover part 2 matches the flange 8 at one end of the cover tube 4 with the flange 11 of the connecting part 9, and further matches the flange 8' at the other end of the cover tube 4 with the flange 11' of the bending part 10, so that each bolt nut 12
It is firmly attached by tightening it.

The connecting portion 9 and the bending portion 10 are configured so that the cloth 7 is sandwiched between two outer wire meshes 5 and an inner wire mesh 6, similar to the overtube 4, and the connecting portion 9 and the flange 1
1, bent portion 10, and flange 11' are fixed by welding, adhesive, or the like.

Here, the connecting portion 9 and the bending portion 10 may be formed of a metal plate without using wire mesh or cloth.

The connecting portion 9 is provided with a pipe 13, and the pipe 13 is provided with a threaded portion 13a. The threaded portion 13a allows the pump 3 to be screwed integrally with the pump 3.

Due to these, even if the cloth becomes clogged and a considerably high pressure is applied, the cloth will not be torn or the connection will not come off.

In the overpart 2 described above, the overtube 4 can be of an optimal length, but the thickness of the overtube 4 can also be selected from different thicknesses as necessary. Of course, the shapes of the connecting portion 9 and the bending portion 10 may also correspond to the thickness of the overtube 4.

FIG. 4 is a front view of the entire system in a state where 1 is the system and 3 is the pump.

The filter device 1 is a device in which the above-mentioned filter section 2 and pump 3 are connected and fixed.The entire filter device 1 is submerged in water such as a reservoir or a public bath, and is connected to an external power source V to supply power to the pump 3. It is used as follows.

In this way, the strainer according to the present invention has only the power cord 16 etc. that supplies power to the pump externally, so it does not get in the way, and there is no need to connect the suction part to the pump, strainer, etc. It occupies a small space and is easy to use.

Further, the pump 3 is provided with a filter 14 for removing coarse gravel and the like on its water suction side, and a connecting pipe 15 with the filter section 2 on its water output side. The end of the connecting pipe 15 is provided with a threaded portion 15 a that faces the threaded portion 13 a of the pipe 13 fixed to the connecting portion 9 .
