Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a filter which is convenient for replacing a filter element. Background Art

[0002] The filter is an indispensable device on the pipeline that conveys the medium. After the water to be treated passes through the filter cartridge of the filter screen, its impurities are blocked.

Although the filter element can also be replaced, it is easy to cause the problem of low disassembly efficiency. The invention comprises a cylinder body, and a cover is arranged on one side of the cylinder body. Through the provided sealing assembly and connecting assembly, when the filter element is replaced, the rubber ring can be driven to rotate in the inner wall of the groove by rotating the cover, and the cover can be removed to separate the cover from the cylinder body, thereby avoiding the existing cylinder body and the cover being connected by multiple screws. When replacing the filter element, each screw needs to be unscrewed one by one to separate the cylinder body and the cover, and then the filter element is replaced, which takes a long time to disassemble, thereby causing the problem of low replacement efficiency. The convenience of disassembling the cylinder body and the cover is improved. The filter provides a way to open the top cover through the cooperation of the card block and the card hole.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figures 1 to 3 In this embodiment, a filter that is easy to replace the filter element includes a wall 1, and four support columns 2 are fixed at the bottom of the wall 1. The setting of the support columns 2 is conducive to the stability of the device operation and provides a guarantee for the operation of the device. A driving mechanism 3 is provided at the bottom of the wall 1, and a lifting platform 8 is movably connected to the four support columns 2. The driving mechanism 3 drives the lifting platform 8 and the structure above it to rise and fall. Two outer cylinders 4 are fixed at the bottom of the wall 1, and the front of the outer cylinder 4 is respectively connected to a liquid inlet 5 and a liquid outlet 6. The liquid inlet 5 is located above the liquid outlet 6. The cooperation between the upper and lower positions is conducive to the outflow of the filtrate. Two limit blocks 7 are fixed on each support column 2.

[0028] It can be known that the limiting cooperation between the support column 2 and the limiting block 7 is conducive to stabilizing the up and down displacement of the lifting platform 8, thereby contributing to the stable operation of the overall device.

[0029] It can be understood that the limit block 7 at the bottom is fixed to the bottom end of the support column 2, and the limit block 7 at the top is in contact with the inner cavity of the lifting platform 8. The setting of the limit block 7 is conducive to limiting the lifting platform 8 and the stability of the lifting of the lifting platform 8. A funnel 9 is fixed to the bottom of the lifting platform 8. The bottom of the lifting platform 8 is provided with four through holes for the movement of the support column 2. The lifting platform 8 is a groove structure with high sides and low middle. An opening is provided at the bottom of the lifting platform 8, and the funnel 9 is connected to the opening. The opening and the funnel 9 are both funnel-shaped. Through the structural setting of the lifting platform 8, a funnel 9 is arranged at the bottom of the lifting platform 8, which is conducive to collecting the residual liquid after the filter component 11 is separated from the outer cylinder 4, and is conducive to preventing the leakage of the liquid. Two fixed blocks 10 are fixed on the top of the lifting platform 8, and the top of the lifting platform 8 is provided with a filter component 11 for filtering and located in the inner cavity of the two outer cylinders 4.

[0030] In this embodiment, the lifting platform 8 is lifted and lowered by the driving mechanism 3 so that the filter assembly 11 is separated from the outer cylinder 4, which simplifies the separation steps of the filter assembly 11 and the outer cylinder 4 and is beneficial to improving the replacement efficiency of the filter element 1104.

[0031] Please refer again Figure 1 and Figure 4 In order to simplify the separation of the cover and the cylinder, the driving mechanism 3 in this embodiment includes a servo motor 301 fixed to the bottom of the wall 1, and a mounting seat is fixed to the top of the servo motor 301. Through the setting of the mounting seat, the normal operation of the servo motor 301 is stabilized, thereby improving the driving stability. The mounting seat is fixed to the bottom of the wall 1, and the output shaft of the servo motor 301 is fixed with a rotating shaft 302.

[0032] The servo motor 301 supplies energy to drive the rotating shaft 302 to rotate, providing a movable basis for subsequent structural lifting, which is conducive to realizing the automation of separation of the filter assembly 11 and the outer cylinder 4, thereby improving the core replacement efficiency.

[0033] It can be understood that two rotating plates 303 are fixed to the outer surface of the rotating shaft 302, and the rotating plate 303 is hinged with a rotating rod 304 at one end away from the rotating shaft 302, and the rotating rod 304 is hinged to the fixed block 10 at one end away from the rotating plate 303, and a limiting column and a limiting disk are fixed to the left side of the rotating plate 303 and the side opposite to the fixed block 10, the limiting column and the limiting disk are fixed, and both ends of the rotating rod 304 are fixed with a ring sleeved on the outside of the limiting column, and through the cooperation of the limiting column, the limiting disk and the ring, the stable operation of the rotating plate 303 and the rotating rod 304 is achieved, which is beneficial to the stable operation of the driving mechanism 3, thereby improving the overall stability of the device.

[0034] In this embodiment, the servo motor 301 is used to supply energy to drive the rotating shaft 302 to rotate. Under the action of the hinge, the angle adjustment of the rotating plate 303 and the rotating rod 304 is achieved, which is beneficial to the lifting and lowering displacement of the lifting platform 8, and is beneficial to simplifying the separation of the filter assembly 11 and the outer cylinder 4, and facilitating the disassembly and replacement of the filter element 1104.

[0035] Please refer again Figure 1 and Figures 5 to 6 In order to cooperate with the lifting and separation of the filter element 1104, the filter assembly 11 in this embodiment includes a chassis 1101 fixed to the top of the lifting platform 8, and a fixing seat 1102 is fixed to the top of the chassis 1101. A plurality of fixing columns are fixed to the top of the chassis 1101. The setting of the fixing columns is conducive to providing a storage space for the filtered liquid, so that the liquid can be transmitted through the liquid outlet 6. The top of the fixing column is fixed to the fixing seat 1102, and the fixing seat 1102 is an inverted T shape. The fixing seat 1102 is composed of a fixing plate and a connecting plate. The bottom of the fixing plate is fixed to the fixing column, and the top of the fixing plate is fixed to the connecting plate. Three clamping holes are opened on the top of the connecting plate. The setting of the clamping holes simplifies the installation method of the filter element 1104 and facilitates the replacement of the filter element 1104.

[0036] The cooperation between the bottom plate 1101 and the fixing seat 1102 facilitates the outflow of the filtrate, provides stability for the transmission of the filtrate, and is beneficial to the operation of the device.

[0037] It should be noted that a sealing ring 1103 is movably connected to the top of the fixed seat 1102, and the sealing ring 1103 is in contact with the inner wall of the outer tube 4. The sealing ring 1103 and the outer tube 4 are in contact with each other, which is beneficial to the stability of the liquid in the outer tube 4 and prevents leakage of the liquid. A filter element 1104 is clamped on the fixed seat 1102, and the clamping hole is clamped with the filter element 1104.

[0038] Furthermore, the coordination of the fixing seat 1102 and the sealing ring 1103 is beneficial to the stability of the filter and improves the stability of the device.

[0039] It should also be noted that the filter element 1104 is located on the inner side of the filter screen 1105, and a plurality of equidistantly distributed filter holes are provided on the outer wall of the filter screen 1105. The setting of the filter holes is beneficial to the flow of the filtrate, thereby providing a guarantee for the transmission of the filtrate. A T-shaped fixing hole compatible with the fixing seat 1102 is provided on the inner side of the sealing ring 1103, and the filter screen 1105 is fixed on the top of the sealing ring 1103.

[0040] In this embodiment, the fixation of the filter screen 1105 and the sealing ring 1103 facilitates the removal of the filter screen 1105 through the sealing ring 1103, providing convenience for the maintenance of the filter. The snap-fit ​​cooperation between the filter element 1104 and the fixing seat 1102 facilitates the disassembly and assembly of the filter element 1104, improves the disassembly and assembly efficiency, and further facilitates the replacement of the filter element 1104.

[0041] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0042] The working principle of the above embodiment is:

[0043] Liquid is injected into the outer tube 4 through the liquid inlet 5, and the liquid passes through the filter screen 1105 to separate larger impurities, completing a preliminary filtration, and then passes through the filter element 1104 to complete a secondary filtration. The filter element 1104 passes through the card hole on the fixed seat 1102 and is located between the sealing ring 1103 and the bottom plate 1101, so that the secondary filtered liquid flows out from the bottom end of the filter element 1104, and finally completes the filtration and is transmitted through the liquid outlet 6. When the filter element 1104 needs to be replaced, the servo motor 301 is started, the shaft 302 rotates, the rotating plate 303 deflects at an angle under the fixing action, and the rotating rod 304 moves downward under the action of the hinge, thereby The fixed block 10 and the lifting platform 8 are driven to move downward along the support column 2, so that the filter assembly 11 fixed on the lifting platform 8 is moved downward. When it drops to the set height, the servo motor 301 is stopped, and the unfiltered liquid remaining in the outer cylinder 4 flows to the lifting platform 8 under the action of gravity, and then the liquid is discharged through the funnel 9. Finally, the filter element 1104 that needs to be replaced is pulled out from the fixed seat 1102 for replacement. Through the lifting effect of the lifting platform 8, the automatic separation of the cylinder body and the cover of multiple filters is realized, which is beneficial to reduce the cover opening time, and then it is beneficial to shorten the speed of replacing the filter element 1104, and speed up the efficiency of replacing the filter element 1104.
