Pipeline online filter with function of manual sewage discharge

Abstract

The invention discloses a pipeline online filter with a function of manual sewage discharge. According to the pipeline online filter, a housing cylinder is provided with a material inlet and a material outlet, the material inlet is arranged on the lower section of the housing cylinder, the material outlet is arranged on the upper section of the housing cylinder, a filtration screen cylinder is arranged inside the housing cylinder and on the upper section inside the housing cylinder, and comprises a center shaft fixedly connected with the filtration screen cylinder body, the upper end of the center shaft penetrates through the housing cylinder, and is connected with a rotation handle, a separation plate is arranged below the filtration screen cylinder, the separation plate region positioned inside the filtration screen cylinder is provided with a plurality of small holes communicated from top to bottom, a position of the separation plate lower surface positioned below the cylinder wall of the filtration screen cylinder is connected with a sewage discharge pipe, and the sewage discharge pipe is provided with a manual valve. During operation, when filtration residues on the filtration screen cylinder are too much, the rotation handle rotates so as to rotate the filtration screen cylinder at a slow speed, the manual valve on the sewage discharge pipe is opened, a filtration process is not affected, and continuous online filtration is achieved.

Description

technical field [0001] The invention relates to a pipeline filter, in particular to an online pipeline filter for manual sewage discharge. Background technique [0002] Pipeline filters are usually used to filter certain impurities in the liquid (or gas) flowing in the pipeline, so that the filtered material can meet the requirements of the system production process. It is widely used in the pipeline system produced by the chemical and pharmaceutical industries. [0003] Existing pipeline filters include conical filters, Y-shaped filters, right-angle filters, etc., which have the characteristics of simple principle and direct filtration, but they must be stopped for cleaning and sewage discharge regularly during operation, which often affects the long-term cycle of system equipment run. Specifically, existing pipeline filters have the following deficiencies: [0004] (1) Filtration effect is unstable: Since the filter mesh specification (mesh size, filter area) in the pipe...

AI Technical Summary

Problems solved by technology

[0004] (1) Filtration effect is unstable: Since the filter mesh specification (mesh size, filter area) in the pipeline filter has been fixed, with the extension of the filtration time, the impurities deposited on the filter will continue to increase, so that the effective filter area will gradually decrease. As a result, the internal resistance of the pipeline continues to increase, and the working (filtration) efficiency gradually decreases, and even causes pipeline blockage in severe cases.

(2) Cannot filter continuously: Since the common pipeline filter cannot remove dirt during operation, after the filter has been working for a period of time, it must be stopped to take out the filter screen (core pulling) for cleaning; if the cleaning timing of the filter cannot be consistent with that of important equipment in the system The synchronization of the planned maintenance cycle will directly affect the long-term operation of the system, resulting in unnecessary system stop and start-up losses
