Description

Technical Field

[0001] This utility model belongs to the field of water treatment filtration technology, and in particular relates to a water treatment filtration device with quick filter media replacement. Background Technology

[0002] Water treatment filtration devices with quick filter media replacement can efficiently purify water. These devices are ingeniously designed and easy to operate, allowing users to replace the filter media in a short time. Their unique structural design ensures the stability and durability of the filtration effect, while also greatly reducing maintenance costs and time.

[0003] The water treatment filtration device with quick-replacement filter media (publication number: CN216934841U) disclosed includes: a filter tank, a baffle plate, and a filter media box. The filter tank is a sealed structure with an internal square cavity. The baffle plate is installed inside the filter tank, dividing its interior into an inlet area and a filtration area. An inlet is located on one side wall of the inlet area, and an outlet is located on one side wall of the filtration area. A predetermined distance is maintained between the bottom of the baffle plate and the bottom wall of the filter tank, connecting the inlet area and the filtration area to form a flow channel. The filter media box is inclinedly installed in the filtration area, penetrating both ends of the filter tank, and is flush with the baffle plate and the side wall of the filter tank. When replacing the filter media in the filter media box, the hinge at the bottom of the box is opened, and the waste filter media is discharged through the filter media outlet, making the replacement and discharge of filter media simple, time-saving, and labor-saving.

[0004] In the aforementioned application, the filter media box and hinge assembly work together, with the filter media box tilted and the bottom hinge discharging the filter media by gravity. This method is only suitable for highly fluid granular filter media. If the filter media becomes damp and clumps, is sticky, or is fibrous or powdery, it is easy to get stuck on the inner wall of the filter media box, the hinge gaps, or the discharge port. Therefore, we propose a water treatment filtration device that allows for quick replacement of filter media. Utility Model Content

[0005] The purpose of this invention is to provide a water treatment filtration device that allows for quick replacement of filter media. By using a lifting and lowering filter media replacement mechanism, it solves the problems of cumbersome and time-consuming filter media replacement in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a water treatment filtration device with quick filter media replacement, comprising: a support frame, a filter box body fixedly connected to the side of the support frame, a sealing top cover fixedly connected to the top of the filter box body, an observation plate rotatably connected to the side of the sealing top cover, and a lifting and changing filter media mechanism provided inside the filter box body. The lifting and replacing filter media mechanism includes a support plate, which is fixedly connected to the top of the sealed top cover. A motor is fixedly connected to the side of the support plate, and a lifting screw is fixedly connected to the output shaft of the motor. The circumferential surface of the lifting screw passes through and is rotatably connected to the top of the sealed top cover. A connecting sleeve is threaded onto the circumferential surface of the lifting screw. A filter media box is fixedly connected to the side of the connecting sleeve. A slider is fixedly connected to the side of the filter media box. A limiting slide plate is fixedly connected to the inner wall of the filter box. The side of the slider is slidably connected to the inner wall of the limiting slide plate. A lead screw sleeve is fixedly connected to the side of the filter media box. A lead screw is slidably connected to the top of the lead screw sleeve. One end of the lead screw is fixedly connected to the inner top wall of the filter box, and the other end of the lead screw is fixedly connected to a stabilizing seat.

[0007] Furthermore, a fixed base is fixedly connected to the inner wall of the filter housing, and the end of the lifting screw away from the motor is rotatably connected to the top of the fixed base. The fixed base on the inner wall of the filter housing can effectively support the lifting screw, preventing the lifting screw from swaying due to one end being suspended when the motor drives the lifting screw to rotate. At the same time, it can distribute the weight of the filter media box borne by the lifting screw, reducing the stress on the motor output shaft.

[0008] Furthermore, the number of limiting slide plates and sliders is four in total, arranged in pairs and symmetrically along the vertical central axis of the filter box. A drain port is connected to the bottom of the filter box. The four limiting slide plates and four sliders provide symmetrical limiting from both sides of the filter box, ensuring even force distribution during lifting and lowering. This prevents the filter box from tilting or jamming due to unilateral force, further improving the stability of lifting and lowering. The drain port at the bottom of the filter box allows for timely discharge of precipitated wastewater, impurities, or residual dirt generated during filter media replacement, preventing impurities from accumulating and clogging pipes or affecting the filtration effect.

[0009] Furthermore, a rotating shaft is rotatably connected to the side of the filter housing, and a sealed maintenance door is fixedly connected to the side of the rotating shaft. The rotating shaft on the side of the filter housing provides a pivot point for the sealed maintenance door, allowing it to open and close flexibly. When the device needs maintenance, opening the sealed maintenance door allows direct access to the lifting and replacing filter media mechanism inside the filter housing without disassembling the entire filter housing, greatly improving maintenance convenience.

[0010] Furthermore, the filter housing is equipped with an anti-clogging cleaning device, which includes a rotating rod. One end of the rotating rod is fixedly connected to the side of the connecting sleeve, and the other end of the rotating rod is rotatably connected to a connecting column. A spring is fixedly connected to the circumferential surface of the connecting column, one end of the spring is fixedly connected to the side of the filter media box, a cleaning wheel is rotatably connected to one end of the connecting column, and a cleaning scraper is fixedly connected to the side of the connecting sleeve.

[0011] Furthermore, the cleaning scraper is located above the cleaning wheel, and the sides of the cleaning scraper and the cleaning wheel are positioned along the displacement trajectory of the filter plate. The cleaning scraper, positioned above the cleaning wheel, can first scrape away larger particles of impurities on the filter plate, preventing these larger impurities from getting stuck on the cleaning wheel. The cleaning wheel then rolls and cleans the remaining fine impurities on the filter plate surface, improving the thoroughness of the cleaning. Since both the cleaning scraper and the sides of the cleaning wheel are positioned along the displacement trajectory of the filter plate, it ensures that both can fully cover the surface of the filter plate during the lifting and lowering of the filter media box.

[0012] Furthermore, an inlet pipe and an outlet pipe are fixedly connected to the side of the filter housing. The inlet pipe fixed to the side of the filter housing can be easily connected to an external water delivery device to ensure a stable flow of water into the filter housing, while the outlet pipe fixed to the side of the filter housing can quickly discharge the filtered clean water, forming a complete water treatment process.

[0013] This utility model has the following beneficial effects: 1. The lifting and replacing filter media mechanism of this utility model does not require the complete disassembly of the filter box or the sealed top cover. The filter box can be quickly lifted and lowered by the motor drive, and the filter media can be directly removed to replace the filter media, reducing the filter media replacement time. The whole process is automatically driven by the motor, without the need for manual handling or disassembly of heavy objects. Only the start and stop of the motor need to be controlled to complete the filter media replacement, reducing the intensity of manual operation, lowering the technical requirements for operators, and making it convenient to use in different scenarios.

[0014] 2. This utility model anti-clogging cleaning device can remove impurities attached to the surface of the filter plate, effectively preventing impurities from clogging the filter plate pores, avoiding problems such as reduced filtration flow rate and deterioration of effluent water quality caused by clogging, ensuring that the filtration device maintains stable water treatment efficiency for a long time, and directly relying on the connecting sleeve of the lifting and replacing filter media mechanism to achieve power linkage.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 This utility model is a water treatment filtration device with quick filter media replacement, including: a support frame 1, a filter box 2 fixedly connected to the side of the support frame 1, a sealing top cover 3 fixedly connected to the top of the filter box 2, an observation plate 4 rotatably connected to the side of the sealing top cover 3, and a lifting and changing filter media mechanism 5 provided inside the filter box 2. The lifting and changing filter media mechanism 5 includes a support plate 51, which is fixedly connected to the top of the sealed top cover 3. A motor 52 is fixedly connected to the side of the support plate 51. A lifting screw 53 is fixedly connected to the output shaft of the motor 52. The circumferential surface of the lifting screw 53 is rotatably connected to the top of the sealed top cover 3. A connecting sleeve 54 is threadedly connected to the circumferential surface of the lifting screw 53. A filter media box 7 is fixedly connected to the side of the connecting sleeve 54. A slider 55 is fixedly connected to the side of the filter media box 7. A limiting slide plate 56 is fixedly connected to the inner wall of the filter box 2. The side of the slider 55 is slidably connected to the inner wall of the limiting slide plate 56. A lead screw sleeve 57 is fixedly connected to the side of the filter media box 7. A lead screw 58 is slidably connected to the top of the lead screw sleeve 57. One end of the lead screw 58 is fixedly connected to the inner top wall of the filter box 2, and the other end of the lead screw 58 is fixedly connected to a stabilizing seat 59.

[0020] As shown in the figure, a fixed base 510 is fixedly connected to the inner wall of the filter housing 2, and the end of the lifting screw 53 away from the motor 52 is rotatably connected to the top of the fixed base 510. The fixed base 510 on the inner wall of the filter housing 2 can effectively support the lifting screw 53, preventing the lifting screw 53 from shaking due to one end being suspended when the motor 52 drives the lifting screw 53 to rotate. At the same time, it can distribute the weight of the filter box 7 borne by the lifting screw 53, reducing the stress on the output shaft of the motor 52.

[0021] As shown in the figure, there are four limiting slide plates 56 and four sliders 55, arranged in pairs and symmetrically along the vertical central axis of the filter box 2. The bottom of the filter box 2 is connected to a drain port 11. The four limiting slide plates 56 and four sliders 55 can symmetrically limit the filter box 7 from both sides, so that the filter box 7 is subjected to uniform force when it is raised and lowered, avoiding tilting or jamming of the filter box 7 due to force on one side, and further improving the stability of the raising and lowering of the filter box 7. The drain port 11 connected to the bottom of the filter box 2 can promptly discharge the sewage, impurities, or residual dirt generated when replacing the filter media in the filter box 2, preventing impurities from accumulating in the filter box 2 and clogging the pipes or affecting the filtration effect of the filter media.

[0022] As shown in the figure, a rotating shaft 12 is rotatably connected to the side of the filter housing 2, and a sealed maintenance door 8 is fixedly connected to the side of the rotating shaft 12. The rotating shaft 12 on the side of the filter housing 2 provides a fulcrum for the rotation of the sealed maintenance door 8, allowing the sealed maintenance door 8 to be opened and closed flexibly. When the device needs maintenance, opening the sealed maintenance door 8 allows direct access to the lifting and replacement filter media mechanism 5 inside the filter housing 2 without disassembling the entire filter housing 2, greatly improving the convenience of maintenance.

[0023] As shown in the figure, the filter box 2 is equipped with an anti-clogging cleaning device 6. The anti-clogging cleaning device 6 includes a rotating rod 61. One end of the rotating rod 61 is fixedly connected to the side of the connecting sleeve 54, and the other end of the rotating rod 61 is rotatably connected to a connecting post 62. A spring 63 is fixedly connected to the circumferential surface of the connecting post 62. One end of the spring 63 is fixedly connected to the side of the filter box 7. A cleaning wheel 64 is rotatably connected to one end of the connecting post 62, and a cleaning scraper 65 is fixedly connected to the side of the connecting sleeve 54.

[0024] As shown in the figure, the cleaning scraper 65 is located above the cleaning wheel 64, and the sides of the cleaning scraper 65 and the cleaning wheel 64 are located on the displacement trajectory of the filter plate. The cleaning scraper 65, positioned above the cleaning wheel 64, can first scrape away larger particles of impurities on the filter plate, preventing these larger impurities from getting stuck on the cleaning wheel 64. The cleaning wheel 64 then rolls and cleans the fine impurities remaining on the filter plate surface, improving the thoroughness of the cleaning. Since both the cleaning scraper 65 and the sides of the cleaning wheel 64 are located on the displacement trajectory of the filter plate, it ensures that both can fully cover the surface of the filter plate during the lifting and lowering of the filter media box 7.

[0025] As shown in the figure, an inlet pipe 9 and an outlet pipe 10 are fixedly connected to the side of the filter housing 2. The inlet pipe 9 fixed to the side of the filter housing 2 can be easily connected to an external water delivery device to ensure that the water to be filtered enters the filter housing 2 stably. The outlet pipe 10 fixed to the side of the filter housing 2 can quickly export the filtered clean water, forming a complete water treatment process.

[0026] A specific application of this embodiment is as follows: When the water treatment filtration device is started, the lifting and changing filter media mechanism 5 is initially in the filtration ready state. Its filter media box 7 is located in the filtration position inside the filter box 2, and the filter media inside the box has been filled. After the filtered water enters the box through the inlet pipe 9, the filter media box 7 begins the filtration operation. When the filter media needs to be replaced after a period of use, the device starts the lifting and changing process. When the filter media needs to be replaced, the motor 52 is powered on and started, and the output shaft rotates clockwise, driving the lifting screw 53 fixedly connected to it to rotate synchronously. Since the lifting screw 53 is connected to the sealed top cover 3 through and rotates, and is supported by the fixed seat 510 at the bottom, there is no suspension or swaying during the rotation. When the lifting screw 53 rotates, the thread on its circumferential surface meshes with the internal thread of the connecting sleeve 54, converting the rotational motion of the screw into the linear motion of the connecting sleeve 54. The connecting sleeve 54 moves upward along the axis of the lifting screw 53. The filter media box 7 fixed on the side of the connecting sleeve 54 rises synchronously with the connecting sleeve 54. The slider 55 on the side of the filter media box 7 slides along the inner wall of the limiting slide plate 56 to limit the lateral displacement of the filter media box 7 and prevent left and right swaying. The screw sleeve 57 on the side of the filter media box 7 slides upward synchronously along the screw 58. With the help of the stabilizing seat 59 to fix the screw 58, the lifting trajectory of the filter media box 7 is further constrained to prevent tilting forward and backward and ensure that the filter media box 7 always rises horizontally. When the filter media box 7 rises to the top with the connecting sleeve 54, its top does not exceed the design height of the sealing top cover 3. The motor 52 is de-energized and stops running. The filter media box 7 stops at the replacement station. The operator can directly open the side cover of the filter media box 7, pour out the waste filter media, and load new filter media without disassembling the filter box 2 or the sealing top cover 3. The operation is convenient.

[0027] Before the filter device starts operating, after a period of time, when impurities begin to adhere to the surface of the filter plate or when cleaning or replacement of the filter media is required, the lifting and replacement filter media mechanism 5 is activated. The output shaft of the motor 52 drives the lifting screw 53 to rotate, causing the threaded connecting sleeve 54 to move upward along the axis of the lifting screw 53. Since one end of the rotating rod 61 of the anti-clogging cleaning device 6 is fixed to the side of the connecting sleeve 54, the connecting sleeve 54 synchronously drives the rotating rod 61, connecting column 62, cleaning wheel 64, and cleaning scraper 65 to move upward along the surface of the filter plate, realizing the synchronous lifting and lowering of the cleaning device and the filter media box 7. The cleaning scraper 65 is located above the cleaning wheel 64 and first contacts the impurities on the surface of the filter plate. Through the upward force, it scrapes off the larger particles of impurities attached to the filter plate from the surface of the filter plate, preventing large particles of impurities from getting stuck in the teeth or gaps of the cleaning wheel 64, preventing the cleaning wheel 64 from getting stuck, and clearing obstacles for subsequent fine cleaning. After the cleaning scraper 65 removes large impurities, the cleaning below... As the device continues to move upward, the rubber protrusions of the cleaning wheel 64 can penetrate deep into the pores of the filter plate, carrying out the fine impurities that the scraper did not clean. At the same time, the rolling friction pushes the residual impurities to the edge of the filter plate, ensuring that the water filtration channels of the filter plate are unobstructed. During the cleaning process, if there are slight unevennesses on the surface of the filter plate, the spring 63 in the device is compressed, causing the connecting column 62 to move slightly backward, preventing the cleaning wheel 64 from damaging the filter plate or itself due to hard impact. When the cleaning wheel 64 encounters a depression, the spring 63 returns to its stretched state, pushing the connecting column 62 forward, so that the cleaning wheel 64 always fits against the surface of the filter plate at the depression, without cleaning dead corners, ensuring that the cleaning effect in different areas is consistent. The cleaned impurities slide down the surface of the filter plate to the bottom of the filter box 2 under the action of gravity, and are finally discharged from the device through the drain port 11 at the bottom of the filter box 2, preventing impurities from accumulating in the box and preventing secondary clogging of the filter plate or contamination of the water to be filtered.
