Technical Field

[0001] The utility model relates to the technical field of filtering equipment, in particular to an activated carbon filter element which is easy to replace. Background Art

[0002] Activated carbon filter element is made of high-quality fruit shell charcoal and coal-based activated carbon as raw materials, supplemented with food-grade adhesives, using high-tech technology and processed by special processes. It integrates adsorption, filtration, interception and catalysis. It can effectively remove organic matter, residual chlorine and other radioactive substances in water, and has the effect of decolorization and removal of odor. It is an ideal new generation product in the liquid and air purification industry.

[0003] After the filter element is used for a long time, various impurities in the water or air will gradually accumulate on the filter element, causing the filter element to be blocked. Therefore, the filter element needs to be disassembled, cleaned or replaced. When using the existing activated carbon filter element, the mounting plate is usually inserted into the corresponding mounting slot or interface, and then fixed with multiple sets of bolts with the help of corresponding tools. However, during the subsequent disassembly and installation, the operation process will appear relatively cumbersome and complicated, and the technical requirements for the operator are relatively high. Improper operation may also cause a certain degree of damage to the filter element or related components, thereby affecting the normal use and performance of the equipment. In view of this, the present application proposes an activated carbon filter element that is easy to replace. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-5 , an activated carbon filter element that is easy to replace, includes a base 1, a mounting cover 6 is provided on the top of the base 1, an outer filter screen 2 and an inner filter screen 3 are respectively provided between the base 1 and the mounting cover 6, and the diameter of the inner filter screen 3 is smaller than the diameter of the outer filter screen 2, and a plurality of supporting devices are provided between the base 1 and the mounting cover 6, the supporting device includes a shaft seat 4 and a supporting frame 5, the shaft seat 4 includes two fixing plates, a pin is provided between the two fixing plates, the pin is rotatably connected with the bottom of the supporting frame 5, and the top of the supporting frame 5 is connected with the abutment block 12, further, the supporting frame 5 rotates with the pin as the axis, and after being connected with the abutment block 12, it can fix the mounting cover 6 to ensure the stability of the overall connection of the filter element.

[0023] A threaded sleeve 7 is penetrated through the top of the mounting cover 6, and a threaded rod 8 is threadedly connected to the threaded sleeve 7. A knob 9 is fixedly connected to the top of the threaded rod 8. The threaded rod 8 is connected to a contact block 12 through an adjusting device. The adjusting device includes a first wedge block 10 and a second wedge block 11, and magnets are respectively provided on the corresponding inclined surfaces of the first wedge block 10 and the second wedge block 11. It should be noted that under the mutual attraction of the two magnets, the inclined surfaces of the first wedge block 10 and the second wedge block 11 always keep in contact. Therefore, along with the movement of the first wedge block 10, the second wedge block 11 can be extended from or retracted into the mounting cover 6.

[0024] The top of the first wedge block 10 is rotatably connected to the threaded rod 8, the second wedge block 11 is connected through the mounting cover 6, and the end of the second wedge block 11 extending outside the mounting cover 6 is fixedly connected to the abutment block 12. It should be noted that, through the setting of the connecting block 14, when the second wedge block 11 arranged under the threaded rod 8 moves, it will drive the multiple second wedge blocks 12 arranged circumferentially to move synchronously, thereby ensuring that the multiple abutment blocks 12 are extended at the same time to fix the position of the filter element, thereby avoiding the filter element from tilting during installation, resulting in uneven force and shaking at the connection with the equipment during subsequent use.

[0025] A plurality of limit plates 13 are fixedly connected to the inner wall of the mounting cover 6, and two adjacent limit plates 13 are respectively arranged on both sides of the first wedge block 10, and the spacing between the two adjacent limit plates 13 is equal to the width of the first wedge block 10. Furthermore, the side walls of the limit plates 13 are in contact with the side walls of the first wedge block 10, and under the guidance of the limit plates 13 on both sides, the first wedge block 10 always keeps vertical movement.

[0026] The adjusting device is connected to a sealing gasket 15 through a connecting seat 14. The connecting seat 14 is set in a circular ring shape, and the connecting seat 14 is connected through the first wedge block 10. The cross-section of the sealing gasket 15 is an inverted trapezoid. The width of the bottom of the sealing gasket 15 is smaller than the distance between the outer filter 2 and the inner filter 3, and the width of the top of the sealing gasket 15 is larger than the distance between the outer filter 2 and the inner filter 3. Furthermore, with the downward movement of the first wedge block 10, the sealing gasket 15 will eventually form a closure on the top of the outer filter 2 and the inner filter 3, so that the untreated gas or liquid is fully in contact with the activated carbon, ensuring the stable operation of the filtration system.

[0027] When the utility model is in use, the filter element is placed in the filter device through the installation groove, the installation cover 6 is moved into the installation interface, and the knob 9 is turned to drive the threaded rod 8 to rotate. Under the limitation of the threaded sleeve 7, the threaded rod 8 will move along the set direction. At the same time, under the fixation of the corresponding limiting plate 13, the first wedge block 10 connected to the bottom of the threaded rod 8 is rotated to move downward, and the second wedge block 11 is driven to extend outward of the installation cover 6 through the abutting inclined surfaces, and finally multiple abutment blocks 12 are moved into the corresponding installation interface at the same time to fix the filter element to avoid skewed installation of the filter element. The operation is relatively convenient and does not require the aid of special tools. At the same time, the first wedge block 10 drives the sealing gasket 15 below to move between the outer filter screen 2 and the inner filter screen 3 to ensure that the inside of the filter element has good sealing performance to avoid leakage of untreated gas or liquid during use.

[0028] When disassembling, the knob 9 is turned in the opposite direction to drive the threaded rod 8 and the first wedge block 10 to move upward. Under the mutual attraction of the magnets on the two inclined surfaces, the second wedge block 11 is retracted into the installation cover 6. At this time, the filter element can be removed from the filtering device. Under the limit of the shaft seat 4, the support frame 5 and the second wedge block 11 are separated. The installation cover 6 can be removed from the top of the outer filter screen 2 and the inner filter screen 3, and the activated carbon inside can be directly replaced. At the same time, it is convenient to clean the outer filter screen 2 and the inner filter screen 3, so that the filter element structural components can be fully utilized and the use cost can be reduced.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
