Description

Technical Field

[0001] This utility model relates to the field of drinking water filtration technology, and in particular to a drinking water activated carbon filtration device. Background Technology

[0002] Currently, activated carbon filters for drinking water require regular replacement of the internal activated carbon particles during use; otherwise, blockages will occur between the activated carbon particles, significantly reducing the filtration and purification effect on the water. Since the activated carbon is dispersed, the replacement process requires a considerable amount of time and manpower.

[0003] Existing technology CN210163167U describes an activated carbon filter for a mineral water raw water treatment system, relating to the technical field of drinking water production. It aims to solve the problem of dispersed activated carbon placement in existing activated carbon filters, which leads to lengthy and labor-intensive activated carbon replacement processes. The filter includes a shell, an inlet, an outlet, an exhaust port, and an observation port on the shell, as well as a support frame inside the shell and a filter media layer placed on the support frame. The inlet is located above the filter media layer, and the outlet is located below the support frame. The filter media layer includes a mesh box and activated carbon particles within the mesh box. An opening is provided at the top of the shell, covered by a top cover that is sealed to the shell. This invention offers the advantage of facilitating activated carbon replacement.

[0004] Although the above-mentioned equipment can replace activated carbon in actual use, some impurities will still adhere to the inner wall of the shell above the filter material layer, making it inconvenient for people to clean it. Utility Model Content

[0005] The purpose of this invention is to provide a drinking water activated carbon filtration device, which aims to solve the problem that existing drinking water activated carbon filters are not easy to clean the impurities adhering to the inner wall of the housing located above the filter media layer.

[0006] To achieve the above objectives, this utility model provides a drinking water activated carbon filtration device, including a housing, a mounting flange provided on the housing, and a scraping mechanism;

[0007] The scraping mechanism includes an upper end cover, a lower end cover, an electric push rod, a movable frame, a water guide cover, an inlet pipe, and an outlet pipe. The upper end cover is screwed onto the top of the housing, and the lower end cover is screwed onto the bottom of the housing. The electric push rod is mounted on the upper end cover and symmetrically arranged. An O-ring seal is installed in the circular hole on the upper end cover through which the actuating rod of the electric push rod passes. The movable frame is slidably connected to the housing and connected to the output end of the electric push rod, and is located inside the housing. An O-ring seal is installed in the mating hole where the movable frame is connected to the electric push rod. The water guide cover is screwed onto the movable frame, and after installation, its top is flush with the top end face of the movable frame. Activated carbon filler is placed in the placement cavity between the movable frame and the water guide cover. The inlet pipe is integrally mounted on the upper end cover, and the outlet pipe is integrally mounted on the lower end cover.

[0008] When the electric push rod extends, the bottom of the movable frame is flush with the bottom of the circular cavity of the housing; when the electric push rod retracts, the top of the movable frame is flush with the top of the circular cavity of the housing.

[0009] The upper and lower end faces of the housing are respectively provided with mounting grooves, which are not connected to the threaded mounting cavities on the housing.

[0010] The inlet pipe and the outlet pipe each have a hexagonal snap-fit ​​part.

[0011] The inlet pipe and the outlet pipe are provided with mating grooves on their connecting flanges, and the mating grooves are not connected to the water passages on the inlet pipe and the outlet pipe.

[0012] The drinking water activated carbon filtration equipment also includes a detection mechanism, which includes a first water quality sensor and a second water quality sensor. The first water quality sensor is installed on the inlet pipe, and the second water quality sensor is installed on the outlet pipe.

[0013] This utility model discloses an activated carbon filtration device for drinking water. During use, the device is fixed by mounting flanges. Furthermore, the flange on the inlet pipe is connected to the flange on the external water source input pipe, and the flange on the outlet pipe is connected to the flange on the outlet delivery pipe. Water enters the interior through the inlet pipe and is filtered by the activated carbon packing within the placement chamber formed by the moving frame and water guide cover. Finally, the water is discharged through the outlet pipe. For cleaning, firstly, the electric push rod is controlled to reciprocate, causing the moving frame to move vertically back and forth, thereby scraping off impurities adhering to the surface of the circular cavity inside the shell. The scraped impurities fall onto the top surface of the moving frame. Then, the connecting bolts of the flanges on the inlet and outlet pipes are removed. Further, the upper or lower end cover is removed, allowing for direct rinsing and cleaning of the interior of the shell or replacement of the activated carbon packing. Because the impurities inside the shell are scraped off by the vertical reciprocating movement of the moving frame, cleaning can be achieved simply by rinsing with clean water. This solves the problem of existing activated carbon filters for drinking water where it is difficult to clean impurities adhering to the inner wall of the shell above the filter media layer.

Detailed Implementation

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Example 1:

[0023] like Figures 1 to 4 As shown, where Figure 1 This is a schematic diagram of the overall structure of an activated carbon filtration device for drinking water. Figure 2 This is a sectional view of the housing 101. Figure 3 This is a sectional view of the movable frame 106. Figure 4 This is a cross-sectional view of the water guide cover 107. This utility model provides a drinking water activated carbon filtration device: it includes a housing 101 and a scraping mechanism. The scraping mechanism includes an upper end cover 103, a lower end cover 104, an electric push rod 105, a moving frame 106, a water guide cover 107, an inlet pipe 108, and an outlet pipe 109. The aforementioned solution solves the problem of existing drinking water activated carbon filters having difficulty cleaning impurities adhering to the inner wall of the housing above the filter media layer. It is understood that the aforementioned solution facilitates the cleaning of the inside of the housing 101.

[0024] In this embodiment, a mounting flange 102 is provided on the housing 101, which facilitates the fixed installation of the equipment.

[0025] The upper end cover 103 is screwed onto the top of the housing 101, and the lower end cover 104 is screwed onto the bottom of the housing 101. The electric push rod 105 is mounted on the upper end cover 103 and arranged symmetrically. An O-ring is installed in the circular hole on the upper end cover 103 through which the actuating rod of the electric push rod 105 passes. The movable frame 106 is slidably connected to the housing 101 and connected to the output end of the electric push rod 105, and is located inside the housing 101. The movable frame 106 and the electric push rod 105 are connected and installed in a mating hole. An O-ring is installed inside. The water guide cover 107 is screwed onto the movable frame 106. After installation, its top is flush with the top end face of the movable frame 106. Activated carbon packing is placed in the cavity between the movable frame 106 and the water guide cover 107. The water inlet pipe 108 is integrally mounted on the upper end cover 103, and the water outlet pipe 109 is integrally mounted on the lower end cover 104. Threaded cavities are provided on the upper and lower sides of the housing 101 to facilitate the installation of the upper end cover 103 and the lower end cover 104. The space between the threaded cavities is a circular cavity to facilitate the installation of the water inlet pipe. The movable frame 106 is provided with multiple water passage holes at the bottom of its vertical circular threaded cavity. The diameter of the water passage holes is smaller than the particle diameter of the activated carbon filler. Mounting holes are provided on both sides, with stepped holes at the top that do not penetrate through the material. An mounting groove is provided inside the larger hole of each stepped hole, and an O-ring is installed for sealing. A threaded hole is provided on the end face of the circular shaft of the output end of the electric push rod 105, facilitating tightening onto the movable frame 106 with bolts. The electric push rod 105 is fixed by bolts, and is installed in the circular hole on the upper end cover 103 through which the actuating rod of the electric push rod 105 passes. An O-ring is provided for sealing. The top end face of the water guide cover 107 is provided with an internal hexagonal hole for easy rotation with an internal hex wrench. Its cross-section is a U-shaped structure with the opening facing downwards. Several water passage holes are provided on the top. The diameter of the water passage holes is smaller than the particle diameter of the activated carbon filler. The water inlet pipe 108 is integrally set on the upper end cover 103. The top flange can be connected and fixed to the flange of the external water source delivery pipe by screws and nuts. The water outlet pipe 109 is integrally set on the lower end cover 104. The bottom flange can be connected and fixed to the flange of the water source output pipe by screws and nuts.

[0026] When the electric push rod 105 extends, the bottom of the movable frame 106 is flush with the bottom of the circular cavity of the housing 101; when the electric push rod 105 retracts, the top of the movable frame 106 is flush with the top of the circular cavity of the housing 101. This structure prevents the movable frame 106 from impacting the upper end cover 103 or the lower end cover 104 during reciprocating movement.

[0027] Secondly, mounting grooves are respectively provided on the upper and lower end faces of the housing 101, and the mounting grooves are not connected to the threaded mounting cavities on the housing 101. O-ring gaskets can be installed in the mounting grooves, which can help improve the sealing performance of the upper end cover 103 and the lower end cover 104 after installation and reduce water leakage.

[0028] Then, the water inlet pipe 108 and the water outlet pipe 109 are each provided with a hexagonal snap-fit ​​part 110. The hexagonal snap-fit ​​part 110 will facilitate the quick installation or removal of the upper end cover 103 or the lower end cover 104, which will be more conducive to quick installation and disassembly compared with the multiple bolt connection structure of the existing equipment.

[0029] Finally, mating grooves are respectively provided on the end faces of the connecting flanges on the water inlet pipe 108 and the water outlet pipe 109. These mating grooves are not connected to the water passage chambers on the water inlet pipe 108 and the water outlet pipe 109. O-ring gaskets can be installed in the mating grooves, thereby improving the sealing performance of the flange connection between the water inlet pipe 108 and the water outlet pipe 109 and reducing leakage.

[0030] When using this invention to solve the problem of existing activated carbon filters for drinking water where it is difficult to clean impurities adhering to the inner wall of the housing above the filter media layer, the device is fixed in use via the mounting flange 102. Furthermore, the flange on the inlet pipe 108 is connected to the flange on the external water source input pipe, and the flange on the outlet pipe 109 is connected to the flange on the outlet water delivery pipe, thus establishing a water supply circuit. Water then enters the housing 101 through the inlet pipe 108 and is filtered by the activated carbon packing material placed in the placement cavity formed by the moving frame 106 and the water guide cover 107. Finally, the water is discharged through the outlet pipe 109. For cleaning, the electric push rod 105 is first controlled to reciprocate. The movement drives the movable frame 106 to move vertically back and forth, thereby scraping off impurities adhering to the surface of the circular cavity inside the housing 101. The scraped impurities fall onto the top surface of the movable frame 106. Then, the flange connecting bolts on the water inlet pipe 108 and the water outlet pipe 109 are removed. Furthermore, the upper end cover 103 or the lower end cover 104 is removed, allowing for direct rinsing and cleaning of the inside of the housing 101 or replacement of the activated carbon packing. Since the impurities inside the housing 101 are scraped off by the vertical reciprocating movement of the movable frame 106, cleaning can be achieved simply by rinsing with clean water. This solves the problem that existing drinking water activated carbon filters are not convenient for cleaning impurities adhering to the inner wall of the housing above the filter media layer.

Based on the first embodiment, this utility model provides a drinking water activated carbon filtration device, which also includes a detection mechanism, including a first water quality sensor 201 and a second water quality sensor 202.

[0033] The first water quality sensor 201 is installed on the inlet pipe 108; the second water quality sensor 202 is installed on the outlet pipe 109.

[0034] In this embodiment, the first water quality sensor 201 can detect the water quality when the water source is input and can feed the detection data back to the control system. The second water quality sensor 202 can detect the water quality when the water source is filtered and output and can feed the detection data back to the control system. The control system can process the data based on the detection data of the first water quality sensor 201 and the second water quality sensor 202 and display the data on an external display, so that users can know in a timely manner whether the water source filtration meets the usage standards.
