[0002] Ultraviolet disinfection equipment has been used in my country for many years. It has the advantages of low cost, small footprint, simple management, and good sterilization effect. The common ultraviolet disinfection equipment in the prior art adopts a horizontal sterilization structure. During the long-term use of the equipment, a lot of sediment will accumulate on the quartz tube, reducing the penetration of ultraviolet light. At the same time, some organic matter will react with ultraviolet light to generate a biofilm adhered to the outer wall of the quartz tube. To remove the biofilm, the quartz tube needs to be manually removed, and then coated with a chemical solvent. After the chemical reaction, the biofilm is manually removed, and then wiped with clean water and put back into the sterilization equipment.

[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] An all-in-one ultraviolet disinfection and cleaning machine has a structure as follows Figure 1 and Figure 2 As shown, it includes a housing 100, a barrel 300 fixed inside the housing 100 and arranged vertically, a cylinder 200 located above the barrel 300 and extended from the housing 100, and a cleaning system 400 located inside the housing 100 and connected to the bottom of the barrel 300. The water inlet 500 is connected to the lower left side of the barrel 300, and the water outlet 600 is connected to the upper left side of the barrel 300. The water to be disinfected and sterilized flows into the barrel 300 from the water inlet 500, and flows out from the water outlet 600 after being disinfected and sterilized by ultraviolet rays. The low-in and high-out method is adopted to avoid dry burning of the ultraviolet lamp.

[0027] The housing 100 is used to contact the ground and support the overall structure. The interior of the housing 100 is used as the installation space for the cylinder 300 and the cleaning system 400. The housing 100 can be made of common metal materials, and the shape is not limited. A conventional shape can be selected. Figure 1In the embodiment, a rectangular parallelepiped structure is adopted, and a control panel 110 is correspondingly provided, on which an electrically controlled touch display screen, an air pump pressure gauge, functional buttons, a buzzer and corresponding indicator lights can be provided.

[0028] The connection between the cylinder 200 and the barrel 300 is as follows: Figure 3 As shown, the cylinder 200 includes a cylinder body 230 and a piston rod 210 located in the cylinder body 230 and capable of reciprocating along the length direction of the cylinder body 230. The cylinder body 230 and the barrel 300 are both arranged vertically, and a cylinder pad is arranged below the cylinder body 230 and fixed to the upper surface of the barrel 300 through a connecting piece. A through hole is provided on the upper surface of the barrel 300, and one end of the piston rod 210 away from the cylinder body 230 passes through the through hole and is located inside the barrel 300. A circular slip ring 220 with an inner diameter of 50 mm is connected to the end of the piston rod 210 away from the cylinder body 230. The slip ring 220 can be made of silicone material, which is fitted on the outside of the quartz tube 310 and reciprocates along the height direction of the barrel 300 with the piston rod 210. Air pipe interfaces 231 are also provided at the upper and lower ends of the cylinder body 230. In a specific embodiment, the air pipe interface 231 can be connected with a high-pressure air pipe with a diameter of 8 mm.

[0029] The barrel 300 is a hollow cylindrical structure, and a plurality of quartz tubes 310 are vertically arranged inside. The quartz tubes are hollow transparent tubular structures, and ultraviolet lamps are arranged inside the quartz tubes 310. The bottom of the quartz tube 310 is located in the mounting seat 311. In a specific embodiment, the mounting seat 311 is a quartz glass tube seat made of stainless steel, which is used to clamp the bottom of the quartz tube 310, and the top of the quartz tube 310 is clamped with the inner wall of the barrel 300. The bottom of the barrel 300 is also provided with an atomizing nozzle 320 connected to the cleaning system 400. The placement direction of the quartz tube 310 is consistent with the movement direction of the piston rod, and each quartz tube 310 is sleeved with a slip ring 220.

[0030] More specifically, a 6mm thick stainless steel connecting plate is provided at the bottom of the cylinder 200, and the specific size can be determined by the equipment power; a 6mm thick 304 stainless steel connecting plate is provided above the cylinder body 300; the two stainless steel connecting plates are fixed and sealed by bolt connectors, and a 4mm thick silicone sealing pad is provided between the two stainless steel connecting plates.

[0031] The structure of the cleaning system 400 is as follows: Figure 4As shown, the cleaning system 400 includes a water inlet pipe 410, an acid inlet pipe 420, a water storage cylinder 430 and a liquid storage cylinder 440. Clean water is injected from the water inlet pipe 410 and then enters the water storage cylinder 430. The other end of the water storage cylinder 430 is connected to the acid inlet pipe 420 through a pipeline and flows to one end of the liquid storage cylinder 440. The other end of the liquid storage cylinder 440 is connected to the atomizing nozzle 320 through a pipeline. The cleaning system 400 is used to add clean water and acid liquid. The acid liquid mainly refers to the chemical agent used to clean the outer wall of the quartz tube. The cleaning system 400 is as shown in FIG. Figure 4 As shown, a plurality of electromagnetic valves (not shown in the figure) for controlling the flow of the pipeline are also arranged on the pipeline. The liquid storage cylinder 440 is mainly used for storing acid or clean water, and the acid or clean water flows through the atomizing nozzle 320 and is sprayed out after being atomized. Figure 1 and Figure 2 As shown, a drain pipe (not marked in the figure) is also provided below the UV disinfection and cleaning machine for discharging the liquid after cleaning.

[0032] In the present invention, an air compressor is used as a power source. Specifically, the air compressor is fixed inside the housing 100 and is connected to the air pipe interface of the cylinder 200, the water inlet pipe 410 and the acid inlet pipe 420 of the cleaning system 400 through electromagnetic valves. By controlling the electromagnetic valves on different lines, the purpose of driving the cylinder 200 to move or pressurizing the clean water or acid solution is achieved.

[0033] In order to reduce management and maintenance costs, the all-in-one machine adopts an intelligent control system. Except for the injection of acid and water and the recovery of waste liquid, which require manual intervention, the rest of the operations are controlled by the intelligent control system. Regarding the use of pressurized atomization, the acid can infiltrate the outer wall of the quartz tube after pressurized atomization to achieve the effect of chemical reaction, and the waste liquid recovery rate can reach more than 95%, which can be recycled to avoid secondary pollution.

[0034] It should be noted that, in the present invention, the ultraviolet disinfection equipment is installed vertically, which has the following advantages: the piston rod slides up and down more smoothly and reliably; the sediment is prevented from settling on the outer wall of the quartz tube; the area occupied by the equipment is reduced; the tail water to be disinfected adopts low inlet and high outlet, and the water outlet is higher than the quartz tube to avoid dry burning; at the same time, a water level switch can be installed on the cylinder, and when the water level is lower than the set water level height, the ultraviolet lamp will automatically stop working.

[0035] In the utility model, the ultraviolet disinfection equipment adopts physical and chemical cleaning, which adds the function of chemical cleaning on the basis of physical cleaning. Its working process is briefly described as follows: first, the water in the cylinder 300 is removed, and then the acid solution is injected to pickle the outer wall of the quartz tube by pressurized atomization. After the acid solution reacts with the biofilm, the piston rod is used to drive the sliding ring to reciprocate so that the sliding ring wipes the outer wall of the quartz tube, and then clean water is injected to wash the outer wall of the quartz tube by pressurized atomization. After washing, the piston rod is used to drive the sliding ring to wipe the outer wall of the quartz tube, and finally the waste liquid and waste water are discharged. It should be noted that the inner wall of the cylinder 300 must be mirror-finished, and the remaining water in the cylinder 300 must be drained before pickling or washing.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
