Description

Technical Field

[0001] The present application relates to the technical field of drinking water disinfection, and in particular to a ceramic membrane bottom valve. Background Art

[0002] At present, the main disinfectant used for disinfection of rural domestic water is sodium hypochlorite solution with an effective chlorine concentration of 10%. However, many small water supply stations in rural mountainous areas are relatively scattered and remote, and it is inconvenient for operation and maintenance personnel to carry sodium hypochlorite solution to the site. Therefore, in most cases, calcium hypochlorite powder with an effective chlorine content of more than 60% is used instead. It is stored and transported in the form of powder, which reduces the burden on operation and maintenance personnel, especially in the case of water supply stations in remote mountainous areas.

[0003] After calcium hypochlorite powder is prepared into liquid in the dosing box, it is then added to the water source through a dosing pump to disinfect the water. However, calcium hypochlorite powder contains many impurities that are difficult to dissolve in water. If the liquid prepared with the powder is directly used for dosing, new pollutants will be introduced into the water source and the dosing pump may be blocked. Utility Model Content

[0022] The present application is further described below in detail through specific embodiments in conjunction with the accompanying drawings.

[0023] In the description of this application: unless otherwise specified, the meaning of "plurality" is two or more. The terms "first", "second", "third", etc. in this application are intended to distinguish the objects referred to, and do not have special meanings in terms of technical connotations (for example, they should not be understood as emphasizing the importance or order, etc.). Expressions such as "including", "comprising", "having", etc. also mean "not limited to" (certain units, components, materials, steps, etc.).

[0024] The terms such as "upper", "lower", "left", "right", "middle", etc. cited in this application are usually used to indicate the general relative position relationship for the purpose of intuitive understanding by referring to the drawings, and are not absolute limitations on the position relationship in the actual product.

[0025] In one embodiment of the present application, a ceramic membrane bottom valve, such as Figure 1 As shown, the bottom valve is arranged in the dosing box 1, and the dosing box 1 is connected to the dosing pump 2; the dosing box 1 is used to store the configured calcium hypochlorite solution 10, and the dosing pump 2 is used to add the calcium hypochlorite solution 10 in the dosing box 1 to the water source, and use the calcium hypochlorite solution 10 to disinfect the water source;

[0026] The bottom valve includes a ceramic ultrafiltration membrane 3 and a float 4. The ceramic ultrafiltration membrane 3 is placed in the solution in the dosing box 1, and the float 4 floats on the surface of the solution. The filtration pore size of the ceramic ultrafiltration membrane 3 is 5nm-100nm. A head 6 is provided at one end of the ceramic ultrafiltration membrane 3, and an adapter 7 is provided at the other end of the ceramic ultrafiltration membrane 3. The adapter 7 is connected to the inlet of the dosing pump 2 through a drug suction tube 9; the head and tail ends of the ceramic ultrafiltration membrane 3 are connected to the float 4 through a traction mechanism 5.

[0027] Preferably, the traction mechanism 5 is a corrosion-resistant wire rope or steel wire rope; for example, the material of the steel wire rope can be a stainless steel wire rope or other material; a wire rope can also be selected, and then a protective layer is coated on the outside of the wire rope, and the protective layer can be selected from plastic materials such as polyethylene (PE), polyvinyl chloride (PVC), etc.

[0028] Further preferably, the two ends of the two traction mechanisms 5 are respectively connected to the two sides of the float 4; the two traction mechanisms 5 are symmetrically arranged and connected to the ceramic ultrafiltration membrane 3, so that the ceramic ultrafiltration membrane 3 can be horizontally located in the calcium hypochlorite solution 10 in the dosing box 1, wherein: one end of the first traction mechanism 5 is connected to one end of the ceramic ultrafiltration membrane 3, and the other end of the first traction mechanism 5 is fixedly connected to one side of the float 4; one end of the second traction mechanism 5 is connected to the other end of the ceramic ultrafiltration membrane 3, and the other end of the second traction mechanism 5 is fixedly connected to the other side of the float 4; in this way, the ceramic ultrafiltration membrane 3 can horizontally "float" in the clearer solution at the top.

[0029] The traction mechanism 5 and the ceramic ultrafiltration membrane 3 can be connected by bonding.

[0030] Preferably, the adapter 7 is a UPVC reducer; it may also be other adapters 7; the advantages of using UPVC material for the reducer are: good corrosion resistance, not easy to rust, corrode or be bio-eroded, less maintenance is required, and the operation and maintenance costs are reduced; light weight; good sealing performance; and certain heat resistance.

[0031] Further preferably, the medicine suction pipe 9 is a soft tube, so that when the liquid level in the medicine adding box 1 rises and falls, the medicine suction pipe 9 will rise and fall together with the bottom valve. If a hard tube is used, this function cannot be achieved.

[0032] Still further preferably, an injection valve 8 is provided between the adapter 7 and the medicine suction tube 9. The function of the injection valve 8 is to realize the connection transition between the soft tube and the hard tube.

[0033] Preferably, the end cap 6 and the ceramic ultrafiltration membrane 3 are connected by food-grade epoxy resin glue.

[0034] Preferably, the adapter 7 and the ceramic ultrafiltration membrane 3 are connected by food-grade epoxy resin glue.

[0035] When the above embodiment is used, after all the components are assembled according to the corresponding connection relationship, the bottom valve is placed in the dosing box 1 configured with the calcium hypochlorite solution 10, and the ceramic ultrafiltration membrane 3 can be horizontally "floated" in the clearer solution in the upper part of the dosing box 1 under the action of the traction mechanism 5 and the float 4;

[0036] Since the filtration pore size of the ceramic ultrafiltration membrane 3 is relatively small, the minimum can reach 5nm, so the ceramic ultrafiltration membrane 3 can effectively filter out the undissolved residue 11 in the calcium hypochlorite solution 10, and the undissolved residue 11 will settle to the bottom of the dosing box 1, while the upper part is a relatively clear solution; finally, the dosing pump 2 sucks the solution filtered by the ceramic ultrafiltration membrane 3 through the drug suction tube 9, and then puts it into the water source to be disinfected through the outlet of the dosing pump 2. Since the ceramic ultrafiltration membrane 3 effectively and fully filters the configured calcium hypochlorite solution 10, there are few impurities in the solution. The calcium hypochlorite solution 10 is treated with the bottom valve and then the water source is disinfected, the disinfection effect is better, and the dosing pump 2 will not be blocked, thereby improving the service life of the dosing pump 2;

[0037] At the same time, the ceramic membrane bottom valve provided by the present application has strong oxidation resistance, can be immersed in sodium hypochlorite solution for a long time, has strong acid resistance, and is easier to clean.

[0038] The technical features of the above embodiments may be arbitrarily combined (as long as there is no contradiction in the combination of these technical features). To make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.
