Description

TECHNICAL FIELD

[0001] The present application relates to the field of carbon rod filter elements, in particular to a sintered carbon rod filter element. BACKGROUND

[0002] The sintered carbon rod filter element is used for removing impurities such as suspended solids, sediments and colloids in sewage, and improving the clarity of the sewage. The sintered carbon rod filter element is formed by using an organic binder and then sintered at high temperature to carbonize the organic binder and form micropores. The main body of the filter element is 100% carbon material. The design of the sintered carbon rod filter element allows embedding of activated carbon particles inside, so as to improve the filtering effect and adsorption capacity. The activated carbon particles are sealed by the end cap.

[0003] However, the end cap of the conventional sintered carbon rod filter element is connected to the sintered carbon rod filter element by threads. Therefore, when the end cap is disassembled for replacement of the activated carbon particles, it is necessary to spend time to disassemble and assemble the end cap by twisting, which is inconvenient for quick disassembly and assembly of the end cap, and results in low efficiency of replacement of the activated carbon particles. CONTENT OF THE INVENTION

[0004] In order to realize quick disassembly of the end cap and shorten the time for replacement of the activated carbon particles, the present application provides a sintered carbon rod filter element.

[0005] The present application provides a sintered carbon rod filter element, which adopts the following technical solution:

[0006] The sintered carbon rod filter element comprises a connecting frame, a sintered carbon rod clamped on the connecting frame, an end cap abutting against one end of the connecting frame, a mesh cover clamped on the end cap, a pressing sleeve clamped on the end cap, a filter screen fixedly connected to the pressing sleeve, the pressing sleeve abutting against one end of the filter screen and the other end of the pressing sleeve abutting against the end cap, a fixing structure provided on the connecting frame, the fixing structure comprising a connecting block and a connecting shaft, four connecting blocks fixedly connected to the connecting frame, the connecting shaft fixedly connected to the connecting block, the connecting shaft penetrating through a positioning block, the four positioning blocks fixedly connected to a connecting sleeve, the connecting sleeve clamped between the end cap, a rotating ring rotatably connected to the connecting sleeve, four protrusions provided on the rotating ring, a ring groove provided on the connecting shaft, the protrusions clamped between adjacent ring grooves, and a limiting structure provided on the connecting sleeve.

[0007] By adopting the above technical solution, the activated carbon can be placed inside the mesh cover for storage. When it is necessary to replace the activated carbon particles inside the mesh cover, the limiting structure can be removed to release the limiting of the rotating ring. Then, the rotating ring is rotated, which drives the four protrusions to move away from the four ring grooves at the same time. When the four protrusions are separated from the inside of the four ring grooves, the connecting sleeve can be moved to separate the connecting shaft and the positioning block.

[0008] Optionally, the vertical section of the top end of the connecting shaft is in a trapezoidal structure, and the four connecting blocks are distributed in a circumferential array about the middle part of the connecting frame.

[0009] By using the above technical scheme, the stability of the end cover after installation can be effectively improved by clamping between the four connecting shafts and the four positioning blocks, and the guiding effect can be achieved when the connecting shafts are inserted into the positioning blocks.

[0010] Optionally, the width of the ring groove is equal to the thickness of the protrusion, and the vertical section of the end of the protrusion close to the ring groove is in a trapezoidal structure.

[0011] By using the above technical scheme, when the protrusion is located inside the ring groove, the movement between the connecting sleeve and the end cover can be avoided, so that the end cover can be blocked by the connecting sleeve, thereby achieving the fixation of the end cover. Since the end section of the protrusion is in a trapezoidal structure, the movement guiding effect can be achieved during the contact between the protrusion and the ring groove.

[0013] By using the above technical scheme, when the rotating ring needs to be rotated, the clamping block can be pushed, and when the clamping block and the clamping groove are not clamped, the rotating ring can be rotated to move the protrusion away from the ring groove. When the protrusion is located inside the ring groove, the clamping block and the clamping groove can be clamped to avoid the rotation of the rotating ring, thereby effectively improving the stability of use.

[0014] Optionally, the support block is fixedly connected with a spring, and the spring is in contact with the clamping block.

[0015] By using the above technical scheme, the clamping block can be clamped with the clamping groove at all times under the action of the spring, thereby improving the stability of use.

[0016] Optionally, the vertical section of the support block is in an L-shaped structure, and the horizontal section of the end of the clamping groove close to the clamping block is in a trapezoidal structure.

[0017] By using the above technical scheme, the guiding effect can be achieved when the clamping block and the clamping groove are clamped.

[0018] Optionally, the end cover is provided with a pressing structure, the pressing structure includes a connecting ring and a spring, the end cover is fixedly connected with the spring, the spring is fixedly connected with the connecting ring, and the connecting ring is in contact with the connecting sleeve.

[0019] By adopting the technical scheme, the connecting sleeve will interfere with the movement of the connecting ring during installation of the end cover, the spring will be contracted during movement of the connecting ring, until the end of the connecting sleeve interferes with the end cover, at which time the spring is in a compressed state, so that the end cover and the connecting frame are tightly pressed by the spring elastic force, thereby effectively improving the sealing performance of the end cover after installation.

[0020] Optionally, the bottom end of the connecting frame is provided with a positioning groove, and the bottom end of the sintered carbon rod is located inside the positioning groove.

[0021] By adopting the technical scheme, the sintered carbon rod can be positioned by the positioning groove during placement.

[0022] To sum up, the present application has at least one of the following beneficial technical effects:

[0023] When it is necessary to replace the activated carbon particles inside the mesh cover, the clamping block can be used, when the clamping block and the clamping groove are not clamped, the rotating ring can be rotated, the rotating ring rotating will drive the four protrusions to move away from the four ring grooves at the same time, when the four protrusions are separated from the inside of the four ring grooves, the connecting sleeve can be moved to separate the connecting shaft and the positioning block, then the connecting sleeve is removed from the end cover, after the end cover is removed, the pressing sleeve is removed, after the pressing sleeve is removed, the mesh cover is not blocked, then the mesh cover can be taken out to replace the activated carbon particles inside, since the end cover can be quickly disassembled during replacement, the replacement time is shortened, and the replacement efficiency is improved.

[0024] After the end cover is disassembled, the sintered carbon rod will not be blocked, so the sintered carbon rod can be taken out from the inside of the connecting frame, thereby facilitating replacement of the sintered carbon rod.

[0025] By adopting the technical scheme, the connecting sleeve will interfere with the movement of the connecting ring during installation of the end cover, the spring will be contracted during movement of the connecting ring, until the end of the connecting sleeve interferes with the end cover, at which time the spring is in a compressed state, so that the end cover and the connecting frame are tightly pressed by the spring elastic force, thereby effectively improving the sealing performance of the end cover after installation.
