Detailed Description

Specific embodiments of the present utility model will be described below with reference to the accompanying drawings. As shown in fig. 1 to 5: a double-body valveless switching type filtering device comprises a switching shell 1, two filtering shells 2 are symmetrically arranged on two sides of the switching shell 1,

The working process of the double-body valveless switching type filtering device provided by the embodiment of the utility model is as follows: under normal working conditions, the plugging mechanism in the switching shell 1 plugs the water purifying port and the sewage port prevented by one filtering shell 2, sewage enters the lower cavity 5 of the switching shell 1 through the sewage inlet pipeline 9, enters the sewage cavity 19 of the filtering shell 2 communicated with the sewage cavity, enters the filtering barrel 21 through the through holes in the horizontal partition plate 18 for filtering, and clean water filtered by the filtering barrel 21 enters the filtering cavity 20 through the outlet on the side wall of the filtering barrel 21 and enters the upper cavity 4 of the switching shell 1 through the water purifying port, and is finally discharged through the water purifying discharge pipeline 8, so that filtering operation is realized;

when the current filter shell 2 works for a certain time and the filter material needs to be cleaned or replaced, an operator can drive the first rotating shaft 6 to rotate through the handle 7, so that the filter shell 2 of the filter material needs to be cleaned or replaced is blocked by the blocking mechanism, and at the moment, the other filter shell 2 is connected into the filter system, so that the filtering operation can be normally performed;

if necessary, the first rotating shaft 6 can be rotated to a state that any one of the filter shells 2 is not blocked by the blocking mechanism, and the two filter shells 2 simultaneously work at the same time, so that the filtering efficiency can be improved;

when one filter shell 2 works for a period of time, a great amount of impurities are deposited in the filter barrels 21 in the filter shell, the filtering effect of the filter barrels 21 is affected, at the moment, the second rotating shaft 22 can be driven to rotate by the handle 7, the second rotating shaft 22 drives the back flushing rotating tube 24 to rotate, the top opening of the back flushing rotating tube 24 is connected with the inlet of one filter barrel 21, in the state, the inlet of the filter barrel 21 is isolated, the water pressure in the filter cavity 20 is necessarily larger than the water pressure in the filter barrel 21, and therefore, the water in the filter cavity 20 reversely flows into the filter barrels 21 through the outlet of the filter barrel 21 and is discharged through the inlet of the filter barrel, so that the back flushing operation of the filter barrels is realized; sewage mixed with the washed impurities enters a back flushing bottom pipe 23 through a back flushing rotary pipe 24 and is finally discharged; when the operation is performed, the back flushing operation of all the filter barrels 21 in one filter shell 2 can be realized only by rotating the second rotating shaft 22 to enable the back flushing rotating pipe 24 to be respectively communicated with all the filter barrels 21 for a certain time; when the back flushing operation is not needed, the back flushing rotary pipe 24 is only needed to be connected with any filter drum 21;

in actual use, marks can be drawn on the top end surfaces of the switching shell 1 and the filtering shell 2, so that operators can judge the current state of the first rotating shaft 6 or the second rotating shaft 22 through the marks;

the first spring 17 is arranged in the plugging mechanism, and the first spring 17 can provide a force for the plugging piston 15 to face the switching shell 1 in one direction, so that the sealing performance of the target clean water gap or the sewage gap can be ensured when the plugging piston 15 is plugged at the clean water gap or the sewage gap; similarly, the second spring 27 can provide an upward force to the sealing head 25 to ensure sealing between the backwash swivel pipe 24 and the inlet of the filter drum 21 when the two are connected.
