Abstract

The utility model relates to a double-cartridge filter comprising a first filter cartridge, a second filter cartridge, a three-way ball valve, an oil inlet and an oil outlet, wherein the inlet of the first filter cartridge and the inlet of the second filter cartridge are connected with the oil inlet through the three-way ball valve; check valves are arranged on the outlet of the first filter cartridge and the outlet of the second filter cartridge; and the outlet of the first filter cartridge and the outlet of the second filter cartridge are connected with the oil outlet. Through the use of the double-cartridge filter with simple structure and convenience in use, the filter cartridges can be cleaned or replaced under the condition of no machine halt, oil is continuously supplied during the cleaning and replacing, and the safety of a system is ensured.

Description

Double-drum filter

Technical field

The utility model relates to a kind of filter, particularly a kind of double-drum filter.

Background technology

Filter comprises monotubular filter and double-drum filter; In the course of the work, the monotubular filter element stops up in the time of to a certain degree need cleaning or more during renew cartridge, stop host work and come more renew cartridge; So not only lose time, more can not satisfy the needs of main frame continuous operation; And existing double-drum filter has solved the defective of monotubular filter this respect, under non-stop-machine situation, capable of washing or more renew cartridge guarantee the main frame normal and continuous operation; But as shown in Figure 1, when T type triple valve switches to another monotubular filter, import and export and switch simultaneously; Therefore can cause the cutout of short time; But this is for heavy duty, and superfast equipment is unallowed; The cutout of this blink can cause serious accident, therefore is badly in need of a kind of double-drum filter and addresses this problem.

Technology contents

The purpose of the utility model is to solve the deficiency of prior art and provide a kind of simple in structure, easy to use, can under non-stop-machine situation, clean or change filter cylinder, and the double-drum filter of oil-break not in the process of cleaning or replacing.

A kind of double-drum filter; Comprise first cartridge filter, second cartridge filter, tee ball valve, oil-in and oil-out; The import of said first cartridge filter and second cartridge filter is connected with oil-in through tee ball valve; Be equipped with check-valves in the outlet of said first cartridge filter and second cartridge filter, the outlet of said first cartridge filter and second cartridge filter is connected with oil-out.

Adopt such scheme, when the filter screen obstruction in the utility model first cartridge filter needs to change, only need the swivel tee ball valve; Like this; Oil just gets into second cartridge filter from oil-in, because tee ball valve has only been closed the oil circuit between the oil-in and first cartridge filter, closes the oil circuit between first cartridge filter and oil-in and the oil-out simultaneously unlike original double-drum filter; Though therefore oil circuit has been changed; But remaining oil still can flow to oil export in first cartridge filter in transfer process, has just remedied the time of oil from second cartridge filter to oil-out, therefore can not cause cutout.

In sum, the utility model is simple in structure, easy to use, can under non-stop-machine situation, clean or change filter cylinder, and oil-break not in the process of cleaning or changing, and has guaranteed the safety of system.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further.

Like Fig. 1,2, shown in 3, double-drum filter is made up of a tee ball valve 6, first cartridge filter 2, second cartridge filter 3 and two check-valves 5, and oil gets into from oil-in 1; Oil circuit along first cartridge filter 2 arrives oil-out 4 through check-valves 5, and the filter screen in first cartridge filter 2 stops up, when needing to change; Swivel tee ball valve 6; Make oil get into second cartridge filter 3,, close the oil circuit between first cartridge filter 1 and oil-in 1 and the oil-out 4 simultaneously unlike original double-drum filter because 6 of tee ball valves have been closed the oil circuit between the oil-in 1 and first cartridge filter 2 from oil-in 1; Though therefore oil circuit has been changed; But 2 li remaining oil of first cartridge filter still can flow to oil export 4 in transfer process, have just remedied the time of oil from second cartridge filter 3 to oil-out, therefore can not cause cutout.

Claims

1. double-drum filter; Comprise first cartridge filter, second cartridge filter, tee ball valve, oil-in and oil-out; It is characterized in that: the import of said first cartridge filter and second cartridge filter is connected with oil-in through tee ball valve; Be equipped with check-valves in the outlet of said first cartridge filter and second cartridge filter, the outlet of said first cartridge filter and second cartridge filter is connected with oil-out.
