Description

TECHNICAL FIELD

[0001] The utility model relates to filter tank structure field especially relates to an improved filter tank connecting assembly. BACKGROUND

[0002] In the metal grinding processing industry, the grinding fluid plays a vital role as a cooling and lubricating medium. The used grinding fluid is treated by a precision filtering device to realize recycling, which not only saves resources but also reduces costs. The filter tank, as the core component of the system, plays an irreplaceable role in ensuring the cleanliness of the grinding fluid and prolonging its service life.

[0003] In practical applications, multiple filter tanks usually operate in groups and are connected to each other through a complex pipeline network. The traditional right-angle connection method is used for the pipeline support point, although the structure is simple, but it is easy to cause uneven fluid distribution, causing the flow rate in local areas to be too high, and thus causing the problem of accelerated wear. In addition, the pressure difference of the grinding fluid entering different filter tanks will affect the service life of the filter element, so that the filter elements in some tank bodies bear excessive load, shortening their working life. Similarly, when the filter element needs to perform a self-cleaning backwashing process, uneven airflow distribution will also reduce the cleaning effect. Over a long period of time, the overall performance and life of individual filter tanks will decrease significantly.

[0004] In view of the above problems, the present application provides a solution. SUMMARY

[0020] Referring to the drawings, Figs. 1-2 The improved filter tank connecting assembly shown by the utility model includes composite liquid inlet pipe 1 and composite liquid outlet pipe 2, wherein the composite liquid inlet pipe 1 is communicated with the bottom liquid inlet of the filter tank 4 through an elbow pipe, and the composite liquid outlet pipe 2 is communicated with the top liquid outlet of the filter tank 4 through an elbow pipe.

[0021] In the embodiment, the bending direction of the bend pipe between the composite liquid inlet pipe 1 and the liquid inlet at the bottom of the filter tank 4 is bending from the direction of the composite liquid inlet pipe 1 towards the bottom of the filter tank 4.

[0022] In the embodiment, the bending direction of the bend pipe between the composite liquid outlet pipe 2 and the liquid outlet at the top of the filter tank 4 is bending from the direction of the liquid outlet at the top of the filter tank 4 towards the composite liquid outlet pipe 2.

[0023] In the embodiment, the side of the filter tank 4 is provided with an overflow port, and the overflow pipe 3 is communicated with the overflow port. The overflow pipe 3 is connected with the overflow port through a bend pipe. The overflow pipe 3 is provided for flushing compressed air in the self-cleaning process of the filter tank 4. When the grinding fluid impacted by the air pressure flows out through the overflow port in the turmoil process, the overflow grinding fluid is guided to flow out.

[0024] In the embodiment, the bending direction of the bend pipe between the overflow pipe 3 and the overflow port at the side of the filter tank 4 is bending from the direction of the overflow port at the side of the filter tank 4 towards the overflow pipe 3.

The filtered grinding fluid is discharged through the clean liquid outlet 9 of the composite liquid outlet pipe 2 for use on the machine.

[0028] When the filter tank 4 needs to be self-cleaned and back-flushed to ensure a longer service life of the filter core, the self-cleaning and back-flushing processes are performed. At this time, the dirty liquid inlet 7 of the composite liquid inlet pipe 1 is closed, and the liquid inlet is stopped. The clean liquid outlet 8 of the composite liquid outlet pipe 2 is closed, and the liquid outlet is stopped.
