DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model, and apparently, the described embodiments only represent some of the embodiments of the utility model, rather than all the embodiments.

[0020] Reference Figs. 1 to 4The utility model provides a double -core filter convenient to replace filter core, including shunt pipe 2, the upper end fixed installation of shunt pipe 2 is communicated with its inside water inlet 1, and the lower end both sides fixed installation is communicated with its inside upper communication pipe 3, and the inside lower fixed installation of upper communication pipe 3 is equipped with upper valve body 8, and the lower contact of upper valve body 8 is equipped with lower valve body 9, and lower valve body 9 rotates and is installed on the inner side wall of upper communication pipe 3, and the lower end detachable installation of upper communication pipe 3 is equipped with with its inside lower communication pipe 4, and the inside movable installation of lower communication pipe 4 is equipped with filter core 11, and the upper end detachable installation of filter core 11 is equipped with end cap 10, and the upper end of end cap 10 is embedded with the lower end of lower valve body 9.

[0021] The lower end detachable installation of filter core 11 is equipped with fixed seat 13, and the outer side movable installation of fixed seat 13 is equipped with rotating baffle 12 through clamping groove, and rotating baffle 12 rotates and contacts with the inner wall of lower communication pipe 4, and the lower end fixed installation of fixed seat 13 is equipped with sealing cover 14, and sealing cover 14 rotates and is set on the lower end outside of lower communication pipe 4, and the lower end fixed installation of sealing cover 14 is equipped with handle 15.

[0022] The lower fixed communication of two lower communication pipes 4 is equipped with connecting pipe 6, and connecting pipe 6 is located on the same horizontal plane with two rotating baffles 12, so that when rotating baffle 12 rotates to a certain position, the port of connecting pipe 6 can be closed, so that the water in lower communication pipe 4 cannot enter connecting pipe 6, and the middle position fixed installation of connecting pipe 6 is equipped with baffle 16, and the middle position fixed installation of connecting pipe 6 is equipped with water outlet pipe 7 communicated with its inside.

[0023] The lower side fixed installation of lower communication pipe 4 is equipped with observation window 5, and observation window 5 is made of transparent material, so that workers can observe the inside situation of lower communication pipe 4 through observation window 5.

[0024] The specific working principle of the utility model is as follows, the liquid needing to be filtered enters from water inlet 1, is divided into two water flows through shunt pipe 2 and enters the closed pipeline formed by upper communication pipe 3 and lower communication pipe 4, and flows out from water outlet pipe 7 after passing through connecting pipe 6 after filtering through left and right double filter cores 11, and the two filter cores 11 of double -core filter can be used alternately, when one filter core 11 needs to be cleaned, replaced or fails, the other can continue to work, so as to ensure the continuity of the whole filtering process.

[0025] When it is observed through the observation window 5 that a filter core 11 in the filter needs to be replaced (taking the replacement of the right filter core as an example), the handle 15 is held and rotated clockwise by a certain angle, the end cover 10 above the filter core 11 drives the lower valve body 9 to rotate, a complete closed valve is formed between the lower valve body 9 and the upper valve body 8, the inflow of liquid in the upper communication pipe 3 is blocked, the liquid in the lower communication pipe 4 continues to flow out from the water outlet pipe 7 under the action of gravity, due to the existence of the partition plate 16 in the connecting pipe 6, when one side conducts liquid export, the other filter core 11 can continue to work and will not affect the replacement side.

[0026] After it is observed through the observation window 5 that the liquid in the lower communication pipe 4 is exhausted, the handle 15 is counterclockwise rotated by a certain angle, the fitting structure between the end cover 10 and the lower valve body 9 is separated, then the handle 15 is pulled downward, the end cover 10 and the lower valve body 9 are separated in the vertical direction, but the fixed seat 13 and the rotating partition plate 12 are not separated, then the handle 15 is continuously rotated, the rotating partition plate 12 which is rotationally connected with the lower communication pipe 4 and embedded in the inner wall of the lower communication pipe 4 closes the right end of the connecting pipe 6, avoiding the inflow of liquid on the left side, causing waste of filtered liquid.

[0027] Then the handle 15 is pulled downward, the filter core 11 is completely pulled out for replacement, after the replacement process is completed, the filter core 11 is completely sent into the lower communication pipe 4 through the handle 15, the handle 15 is continuously rotated clockwise, first, the end cover 10 is re-fitted with the lower valve body 9, then the end cover 10 continues to drive the lower valve body 9 to rotate, until the rotating partition plate 12 is opened under the driving of the fixed seat 13, the closure of the connecting pipe 6, and the hole between the lower valve body 9 and the upper valve body 8 is completely matched, the liquid enters the lower communication pipe 4 to continue filtering, and the replacement process of the filter core 11 is completed.

[0028] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
