Abstract
Description
The present invention relates to a self-cleaning strainer, and more particularly to a self-cleaning strainer that can remove the foreign matter attached to the strainer through the suction pipe automatically without shutting down the equipment.
In order to remove foreign substances (impurities, sludges, contaminants, etc.) contained in the flow fluid, a mesh-type filter or strainer is used. In the case of the strainer connected to the pipe, it includes an inlet pipe and an outlet pipe, it is configured to filter the foreign matter to the strainer by installing a strainer in the form of a big net between the inlet pipe and the outlet pipe.
If the foreign matter attached to the strainer is saturated, replace the filter with the line stopped, and use the method such as washing the strainer or using reverse flow. For example, the Republic of Korea Patent No. 10-0768080, a technology such as 'filter device with a screen brush' is known.
A further improvement over the above technique is a self-cleaning filter or strainer capable of automatically recovering foreign matter attached to the strainer without stopping the flow of the pipe. Examples include 'fluid filtering device' of Republic of Korea Patent Publication No. 10-2010-0009164 and 'improved self-cleaning filter' of Republic of Korea Patent Registration 10-0905698.
In the Republic of Korea Patent Registration 10-0905698 'improved self-cleaning filter, the turbulence generator 400 is attached to increase the suction efficiency of the foreign matter attached to the filter to promote the generation of turbulence in the filter and the elastic means 316 and A nozzle 310 including a suction pipe portion 315 is disclosed.
The above technique can be rotated at high speed to form turbulent flow, but when rotated at high speed, centrifugal force acts so that foreign matters are more attached than separated from the screen filter, and the suction efficiency of foreign matters decreases due to high speed rotation. do. In addition, since the nozzle has elastic means, the nozzle and the screen filter come into contact with each other, which causes damage to each other, which reduces suction efficiency.
All of the above techniques include only a rotating motor, so that foreign matters cannot be completely removed from the filter, and the foreign matters larger than the suction pipe have limitations.
The present invention relates to a self-cleaning strainer for automatically removing the foreign matter attached to the strainer without interrupting the flow of the pipe for cleaning and maintenance, to increase the foreign matter removal efficiency.
The self-cleaning strainer of the present invention to solve the above problems is a body having fluid inflow and outflow pipes each having an inlet pipe and outlet pipe, a strainer in the form of a net in the receiving portion in the body, installed inside the body and settled in the strainer A self-cleaning strainer comprising a hollow rotating shaft having a plurality of suction pipes for sucking foreign matters, the hollow rotating shaft being vertically installed while passing through the center of the body to be rotated by a motor; It characterized in that it comprises a length adjusting means for moving the hollow shaft in the vertical direction.
In addition, the length adjusting means of the present invention and the hydraulic cylinder for vertical reciprocating motion; A shaft fork for transmitting the reciprocating motion of the hydraulic cylinder to the hollow rotating shaft; A sleeve connected to the shaft fork and fastened to one end of the hollow shaft; One end of the solid rotating shaft and the hollow rotating shaft is characterized in that the pin or spline form.
In another aspect, the present invention and each suction pipe connected to the hollow rotating shaft; The suction tube may include an elastic member having a solid shape at one end of the suction tube to collect foreign substances attached to the strainer to improve suction efficiency of the suction tube.
Finally, the present invention provides a body that can accommodate a certain amount of foreign matter away from the strainer, which is bulky or heavy, a hollow rotating shaft passing through the center of the body, a suction hole formed at one end of the hollow rotating shaft, and the suction Including a suction valve that can open and close the hole, it is characterized in that it is also possible to discharge foreign substances collected in the lower part of the body or bulky and heavy materials that cannot be sucked into the suction pipe.
The self-cleaning strainer according to the present invention can be used semi-permanently as it can automatically remove debris during system operation without stopping the pipe line for cleaning and maintenance.
In addition, the combination of the rotary motor and the hydraulic cylinder can completely remove the foreign matter attached to the entire area of the inner wall of the strainer, and by improving the suction power by minimizing the suction pipe can improve the cleaning ability of the strainer.
In addition, the present invention has the advantage that can be expected a more effective suction effect due to the elastic member of the solid shape at one end of the suction pipe.
Finally, the present invention can collect the large foreign matter that can not be sucked into the suction pipe, the foreign matter separated during the cleaning process can be discharged to the outside.
