Abstract
Description
Technical Field
[0001] This utility model relates to the field of water treatment technology, specifically to a nitrate removal device for drinking water. Background Technology
[0002] Nitrates themselves are harmless, but in the human body or in oxygen-deficient environments such as household water purifiers that have not been replaced for a long time, they may be converted into nitrites by nitrate-reducing bacteria. Therefore, drinking water is usually filtered using granular ion exchange resins.
[0003] Chinese Patent CN212712858U discloses a nitrate removal water purification device. This utility model utilizes the cooperation between a water distributor and graded filter media. Under the action of the filter screen, the filter media, namely ion exchange resin, allows the anions in the ion exchange resin to undergo an ion exchange reaction with nitrate ions in drinking water. This causes nitrate and nitrite ions in the water to be adsorbed onto the ion exchange resin, thereby allowing the anions on the original ion exchange resin to enter the water, completing the removal of nitrate and nitrite ions. This method does not damage water quality or increase the salinity of the effluent, making it suitable for widespread use.
[0004] During use, the above-mentioned equipment has a good filtration effect on nitrates through the filter media, namely ion exchange resin. However, in the above-mentioned nitrate removal water purification device, the filter media is directly filled into the tank. To a certain extent, this ensures that the water flow and the filter media are in full contact, thereby improving the purification efficiency. However, when the filter media reaches the end of its service life and needs to be replaced, the staff often have to take the filter media out of the tank bit by bit. The replacement process is time-consuming and laborious. Moreover, the dense accumulation of the filter media makes the removal process extremely difficult. This needs to be optimized and improved. Utility Model Content
[0005] The purpose of this invention is to provide a nitrate removal device for drinking water, so as to solve the problem of the above-mentioned background technology where the filter media is difficult to replace.
[0006] To achieve the above objectives, this utility model provides the following technical solution:

A cleaning assembly mounted on the holding container, including a cleaning element mounted on the holding container, and a sponge plate mounted on the cleaning element; the cleaning assembly for cleaning the holding container.
[0008] Preferably, the lifting assembly further includes a fixed ring disposed at the upper end of the device body, the filter bag opening is disposed at the lower end of the fixed ring, vertical rods are disposed on both sides of the inner wall of the device body, a lead screw is rotatably disposed at one end of the fixed ring, and a limit rod is disposed at the other end.
[0009] Preferably, the connecting block is threaded on the outside of the lead screw, and a T-shaped groove is provided on the vertical rod corresponding to the connecting block. The connecting block is movably disposed in the T-shaped groove, and another set of connecting blocks is disposed on the limiting rod.
[0010] Preferably, one end of the connecting block is provided with a base plate, and one end of the filter bag is provided at the top of the base plate.
[0011] Preferably, a rotating component is provided at one end of the lead screw.
[0012] Preferably, the cleaning assembly further includes a connecting rod disposed at one end of the cleaning component, and a handle is provided at one end of the connecting rod.
[0013] Preferably, one end of the connecting rod is provided with a slider, and the container is provided with an arc groove corresponding to the slider. The slider is movably disposed in the arc groove, and the sponge board contacts the inner wall of the container.
[0014] Preferably, the lower end of the container is provided with a connecting hose, and the container is provided with a discharge port corresponding to the connecting hose, and the discharge port is connected to the connecting hose.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] By moving the connecting block up and down, the base plate can be moved up and down, which makes it easy to squeeze the filter media that needs to be replaced out of the main body of the device and let the filter media fall onto the holding part. This reduces the time required for the staff to replace the filter media, reduces the difficulty of replacement, and effectively avoids damage to the main body of the device when replacing the filter media.
[0017] By pushing the cleaning component, the sponge plate can clean the inner wall of the container, preventing filter media residue from remaining on the inner wall of the container. This effectively avoids environmental pollution when the filter media is replaced, thereby reducing the workload of staff. Attached Figure Description

Detailed Implementation
[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0028] like Figure 1-6 As shown, this application provides a nitrate removal device for drinking water, including a device body 1, a top cover 2 on the device body 1, a lifting assembly on the device body 1, a connecting block 13 on the device body 1, a filter bag 9 on the device body 1, and a holding component 3 on the outside of the device body 1. The lifting assembly is used to remove the filter material.
[0029] Specifically, such as Figure 3 As shown, the lifting assembly also includes a fixed ring 6 set at the upper end of the main body 1 of the device. The opening of the filter bag 9 is set at the lower end of the fixed ring 6. Vertical rods 8 are set on both sides of the inner wall of the main body 1 of the device. A screw 12 is rotatably set at one end of the fixed ring 6, and a limit rod 20 is set at the other end. By rotating the screw 12, the filter bag 9 can be driven to move up and down, which can facilitate the replacement of the filter material by the staff.
[0030] Specifically, such as Figure 4 As shown, the connecting block 13 is threaded on the outside of the lead screw 12, and the vertical rod 8 is provided with a T-shaped groove 11 corresponding to the connecting block 13. The connecting block 13 is movably disposed in the T-shaped groove 11. Another set of connecting blocks 13 is disposed on the limiting rod 20. By setting the T-shaped groove 11, the connecting block 13 can be limited, and by rotating the lead screw 12, the connecting block 13 can be driven to move up and down.
[0031] Specifically, such as Figure 4 As shown, a base plate 10 is provided at one end of the connecting block 13, and one end of the filter bag 9 is provided at the upper end of the base plate 10. Since the filter bag 9 is made of a soft and foldable material, the filter material inside the filter bag 9 can be pushed out by the up and down movement of the base plate 10, thereby enabling the replacement of the filter material.
[0032] Specifically, such as Figure 3 As shown, a rotating part 7 is provided at one end of the lead screw 12. By rotating the rotating part 7, it is convenient for the staff to control the rotation of the lead screw 12.
[0033] The container 3 is equipped with a cleaning assembly, which includes a cleaning component 4 disposed on the container 3 and a sponge plate 18 disposed on the cleaning component 4. The cleaning assembly is used for cleaning the container 3.
[0034] Specifically, such as Figure 6 As shown, the cleaning assembly also includes a connecting rod 16 disposed at one end of the cleaning component 4. A handle 17 is provided at one end of the connecting rod 16. By pushing the handle 17, the connecting rod 16 can be rotated.
[0035] Specifically, such as Figure 6 As shown, a slider 15 is provided at one end of the connecting rod 16, and an arc groove 14 is provided on the container 3 corresponding to the slider 15. The slider 15 is movably disposed in the arc groove 14, and the sponge plate 18 contacts the inner wall of the container 3. By controlling the slider 15 to slide inside the arc groove 14, the sponge plate 18 can clean the inner wall of the container 3.
[0036] Specifically, such as Figure 6 As shown, a connecting hose 5 is provided at the lower end of the container 3, and a discharge port 19 is provided on the container 3 corresponding to the connecting hose 5. The discharge port 19 is connected to the connecting hose 5. The replaced filter media can enter the connecting hose 5 through the discharge port 19, and the staff can centrally process the replaced filter media through the connecting hose 5.
[0037] In this embodiment: by controlling the rotation of the lead screw 12, the connecting block 13 can be driven to move up and down in the T-shaped slide groove 11, which can drive the base plate 10 to move, thereby pushing out the filter material inside the filter bag 9 so that the filter material can fall into the container 3, which can reduce the difficulty of replacement and avoid damage to the inner wall of the device body 1 when replacing the filter material. By pushing the handle 17, the cleaning component 4 can be driven so that the sponge plate 18 cleans the inner wall of the container 3, which can avoid pollution of the working environment when replacing the filter material.
[0038] The specific solution is as follows: Since the filter material is placed inside the filter bag 9, and both ends of the filter bag 9 are connected to the bottom plate 10 and the fixed ring 6, when the filter material needs to be replaced, the rotating part 7 is rotated, which drives the screw 12 to rotate. This causes the connecting block 13 to slide up and down inside the T-shaped slide groove 11. When the bottom plate 10 moves up and down, it can push the filter material inside the filter bag 9 out, so that the filter material can fall into the container 3. The staff can collect the filter material through the connecting hose 5, which makes it convenient for the staff to centrally process the filter material. By pushing the handle 17, the slider 15 can slide in the arc groove 14, which can drive the sponge plate 18 on the cleaning part 4 to clean the inner wall of the container 3, thereby greatly reducing the difficulty of the work and reducing the workload of the staff.
[0039] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary; within the framework of this invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of this invention as described above, which are not provided in detail for the sake of brevity.
