The strainer of the present invention consists of a long conical cylindrical strainer body and a strainer. The cage-shaped stop bar installed at the short diameter end of the main body has an inner diameter that is similar to that of the strainer main body. A strainer held in a pipe-shaped casing that is approximately the same as the long diameter of the Therefore, the strainer body and stop bar are formed by punching metal. The stop bar is equipped with a handle that is approximately the same length as the strainer body. It has a structure that is eclipsed.

[0005] Embodiments of the present invention will be described in detail below with reference to the drawings. The drawing is an example of the present invention. Figures 1 to 3 are perspective views showing each part of the strainer of the present invention, and Figure 1 is a strainer of the present invention. Figure 2 shows the stop bar, and Figure 3 shows the casing. Figure 4 is a cross section showing the strainer of the present invention when assembled using the parts shown in Figures 1 to 3. It is a diagram.

[0006] As shown in Figures 1 to 4, the strainer of the present invention has a long conical cylindrical strainer body. 1 (Fig. 1), stop bar 2 (Fig. 2), and pipe-shaped casing 3 (Fig. 3). The stop bar 2 is inserted from the long diameter side of the strainer body 1 and then inserted from the short diameter side. It is formed from a cage-shaped part 4 and a handle 5 for removal so as to be locked at the side end part, and the handle 5 is provided to have approximately the same length as the strainer main body 1 (FIG. 4). In addition, in Figure 4 The flow direction of the liquid is the direction shown by arrow 9. The material of the cage-shaped part 4 of the strainer body 1 and the stop bar 2 has fine holes all over the surface. It is made of punched metal with In addition, the inner diameter of the casing 3 is approximately the same as the outer diameter on the long diameter side of the strainer body 1. The end of the casing 3 is provided with threads 6 for connecting pipes. . In the present invention, as shown in FIG. A protrusion 8 is provided, and the protrusion is shaped so as to lock into the opening on the short diameter side of the strainer main body. It can also be done. Aperture

[0007] Although the size of the strainer 7 of the present invention is not particularly limited, the solid matter removal efficiency is It is proportional to the size (area) of the strainer body, so it depends on the purpose of use of the strainer. The length and diameter may be selected as appropriate. Usually, the large diameter of the strainer 7 is - Formed to have approximately the same inner diameter as the casing 3, and approximately the same length as the casing. is preferable. In addition, the material and pores forming the strainer body 1 and stop bar 2 are punched. There are no particular limitations on the size of the solids in the liquid to be removed. It can be selected as appropriate depending on the size and type of liquid. Usually punched metal As the material, stainless steel or the like is used.

[0008] Next, the operation of the strainer 1 of the present invention will be explained. Figure 5 shows the storage of the present invention. The strainer 7 of the present invention is installed in the pump 10. A place connected to a suction port to remove solids contained in the water 12 in the bathtub 11 and purify the water. This is a schematic diagram of the case. As shown in FIG. 5, the short diameter side of the strainer body 1 of the strainer 7 of the present invention is Connect to the suction port of the pump 10. The water containing solids sucked by the pump 10 is Punching metal enters from the long diameter side of the strainer body 1 and reaches the outlet on the short diameter side. filtered through the pores formed by the pores (or etched metal). Solids larger than the diameter remain inside the strainer body 1, and the solids are removed. Only the water that has been drained enters the pump 10, and then enters the bathtub 11 again from the pump piping outlet to purify the water. can do.

[0009] In this case, the solids inside the strainer body 1 are removed by the flow of liquid. In order to move in the direction of the tip of the gun body 1 (i.e., the cage-shaped part 4 of the stop bar 2) In this case, the solids first collect at the tip of the strainer and enter the inlet of the strainer body 1. It gradually accumulates toward the side (longer diameter side). Therefore, during use, solid objects may cause Even if the tip of the strainer becomes clogged, it can be moved toward the inlet side of the strainer body 1. As long as there are still parts that are not clogged with solids, the solids can be effectively separated and the liquid can be pumped out. can be sent to the pump side.

0010 Also, remove solids that are stuck at the tip of the strainer by using the handle 5 of the stop bar 2. It can be easily removed by grasping it, pulling it out, removing it externally, and cleaning it. moreover , remove the solid matter adhering to the inner wall of the strainer body 1 by pulling out the stop bar 2. When straining, the cage-shaped portion 4 moves along the tapered inner wall of the strainer body 1. At the same time, the stop bar 2 must be removed in order to drag the solid matter attached to the inner wall. It can be removed at the same time as it is taken out.

[0011] The strainer of this invention operates continuously for long periods of time, like a home-use flow purification device. It can be used as a filter to remove hair etc. when cleaning is performed, or as a filter that is difficult to clean. Ideal as an oil strainer and strainer for difficult applications such as long-term cleaning and inspection. It is.

0012 The present invention will be updated by giving specific examples of actual use of the strainer of the present invention. will be explained in detail. Figure 5 shows an example of the use of the strainer of the present invention. This is an explanatory diagram when the cleaner 7 is used as the filter part of the household flow purification device 14. be. In FIG. 5, the flow purifying device 14 includes a pump section 15 and an inlet side of the pump section. a filter section 16 for removing solid matter such as hair and thread waste; A natural stone that decomposes bacteria, bacteria, etc. is provided on the discharge port side of the pump part 15. It is composed of a filtration device 17.

[0013] Example 1 A strainer formed into a conical cylinder shape as shown in Fig. 4 is used on a household floor as shown in Fig. 6. It was used as the filter part 16 of the purification device 14, and a continuous filtration test of hot water was conducted. Ta. As a result, the stop bar was taken out and cleaned once a month, but during that time it became clogged. Good continuous operation was possible without problems such as abnormal suction of the pump due to . The stop bar was extremely easy to remove and clean.

[0014] Comparative example 1 For comparison, a flat filtration type that combines urethane foam and stainless steel mesh plate is used. Same as Example 1 except that the filter was used in place of the strainer of Example 1. The test was conducted. As a result, it was necessary to clean the filter every day.

[0015]

[Effect of the idea] As explained above, the strainer of the present invention has a long conical cylindrical strainer body. As a result, solids accumulate sequentially from the tip of the strainer. This prevents clogging for a long period of time until solids accumulate on the long diameter side of the strainer body. It has the effect of being able to perform stable separation of solids, and the strainer itself Since a cage-shaped stop bar is formed on the short diameter end of the The solids that accumulate in the cage inside the tank can be easily removed by pulling out the stop bar. The tapered strut can be removed when the stop bar is pulled out. Solid matter on the inner wall of the laner can also be removed to the outside at the same time. In addition, the strainer body and stop bar are made of punched metal. This prevents solids from coming from the inner wall of the strainer body or the cage-shaped part of the stop bar. The interior is easy to clean because it is easily peeled off. Furthermore, the handle of the stop bar is formed to have approximately the same length as the strainer body. This makes it easier to pull out the stop bar from the strainer inlet side. It has various practical effects such as:
