Problems solved by technology

[0002] At present, the high-pressure emulsion in coal mines needs to be filtered and then recycled. Generally, it is filtered by a filter. Due to the harsh environment in the mine, after a period of use of the filter, a lot of impurities will adhere to the filter, and these impurities will affect the filtration of the filter element. speed and filtration efficiency, therefore, the filter element needs to be cleaned in time
At present, the filter element needs to be removed and cleaned, which requires the machine to be shut down to replace the filter screen, which affects normal production, and at the same time, the cost is high and the replacement time is long

Embodiment Construction

[0019] The present invention will now be further described in detail in conjunction with the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only schematically illustrate the basic structure of the present invention, and therefore only show the configurations related to the present invention.

[0020] Such as Figure 1-4 As shown, the double filter for backwashing includes a first filter 1 and a second filter 2. The inside of the first filter 1 is divided into an outer cavity I11 and an inner cavity I12 by a filter screen I. The first filter One side of 1 is provided with a first liquid collection chamber 13 communicating with the outer chamber I11, and the other side is provided with a second liquid collection chamber 14 connected with the outer chamber I11, and the first liquid collection chamber 13 is provided with The first liquid inlet 131 communicated with the system liquid inlet pipe I, the second liquid collection chamber 14 is...

Abstract

The invention belongs to the technical field of filter systems, relates to a filter system for cleaning a filter by utilizing a back washing principle, particularly to a double filter parallel filter system, and aims to provide a filter system fast to clean and capable of cleaning a filter screen without being dismounted. According to the filter system, two filters are connected in parallel, and the working condition of the two filters is controlled through switching of condition conversion valves; in back washing, one filter filters an original emulsified liquid, and the other filter is cleaned by utilization of the filtered cleaning emulsified liquid. The cleaning time is short, the cleaning effect of the filters is good, and secondary pollution can be avoided.

Description

technical field [0001] The invention belongs to the technical field of filtering systems, and relates to a filtering system using the principle of backwashing to clean filters, in particular to a filtering system with double filters connected in parallel. Background technique [0002] At present, the underground high-pressure emulsion in coal mines needs to be filtered and recycled. Generally, it is filtered by a filter. Due to the harsh environment in the mine, a lot of impurities will adhere to the filter after a period of use, and these impurities will affect the filtration of the filter element. Speed ​​and filtration efficiency, therefore, the filter element needs to be cleaned in time. At present, the filter element needs to be removed and then cleaned, which requires shutdown to replace the filter screen, which affects normal production, and at the same time, the cost is high and the replacement time is long. Contents of the invention [0003] The invention overcom...
