Description

Technical Field

[0001] The present invention relates to the technical field of disinfection equipment, and particularly to a medium-pressure ultraviolet water disinfection treatment device. Background Technique

[0002] Various bacteria, viruses, and molds are contained in domestic drinking water, swimming pools, water feature pools, etc. In order to disinfect the water quality, disinfectants are added or ultraviolet sterilization treatment is carried out. Among them, ultraviolet sterilizers have the advantages of being pollution-free, residue-free, safe and reliable, etc., and are widely used.

[0003] Ultraviolet sterilizers are divided into low-pressure ultraviolet and high-pressure ultraviolet. Low-pressure ultraviolet lamps only emit single-wave ultraviolet rays with wavelengths of 185nm and 254nm. The pressure of the inert gas filled in the lamp is lower than the atmospheric pressure by about 0.013 MPA, in a negative pressure state, while the pressure of the inert gas filled in the medium-pressure ultraviolet lamp is equal to the atmospheric pressure, which is 100 times that of the low-pressure lamp, and can emit a wider range of multi-wavelength ultraviolet rays. Therefore, medium-pressure ultraviolet is more suitable for disinfecting swimming pools. After being irradiated by medium-pressure ultraviolet, the DNA strands of bacteria in the water are damaged, thus achieving the effect of rapid disinfection.

[0004] In the existing medium-pressure ultraviolet disinfection equipment, an ultraviolet disinfection lamp, an inlet pipe, and a discharge pipe are installed in the tube sleeve. Water is introduced into the tube sleeve through the inlet pipe, and after being irradiated by the ultraviolet disinfection lamp, the disinfection effect is achieved, and then it is discharged through the discharge pipe. However, the ultraviolet disinfection lamp can only irradiate the surface of the ultraviolet lamp tube. When the amount of water introduced through the inlet pipe is much larger than that in the sleeve, the water near the lamp tube position is disinfected first. The remaining killed bacteria in the disinfected water will prevent the water above from fully receiving the ultraviolet lamp irradiation. At the same time, during practical use, the killed algae and bacteria in the water quality will adhere to the outside of the lamp tube, reducing the irradiation area of the ultraviolet light. For this reason, we propose a medium-pressure ultraviolet water disinfection treatment device. Summary of the Invention

Specific embodiments

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Please refer to Figures 1 - 13, the present invention provides a technical solution: a medium-pressure ultraviolet disinfection water treatment device, including an installation sleeve 1. The installation sleeve 1 is a tubular structure with a through hole in the middle, and its two end faces are flange mounting surfaces. An electric control device 11 is installed on the installation sleeve 1. The electric control device 11 includes a power switch, an indicator light, a timer, an ultraviolet intensity display, a water temperature sensor, a remote control switch, and an alarm device, etc. The timer can record the working time and give a reminder when the lamp tube needs to be replaced. The on-line intensity detection device of the lamp tube uses a wet probe and gives an alarm when the actually detected ultraviolet intensity is lower than the set level. The control cabinet and the ultraviolet reactor must be installed separately to prevent the control system from malfunctioning due to reasons such as water leakage in the reactor. Sealing covers 13 are respectively assembled at both ends of the installation sleeve 1, and a backing plate 14 is connected between the sealing cover 13 and the sleeve. An inlet pipe 15 is installed on one side of the installation sleeve 1, and a discharge pipe 16 is installed on the other side of the installation pipe; the height of the inlet pipe 15 from the ground is higher than the height of the discharge pipe 16 from the ground, and one end of the inlet pipe 15 is connected with a transition sleeve 17, and a spherical section is provided on the transition sleeve 17. Here, the backing plate 14 is installed at the installation sleeve 1 through the flange mounting surface, and then the sealing cover 13 is installed outside the backing plate 14 through fixing connectors such as pins. The sealing cover 13 plays a role of sealing and protecting the backing plate 14. At the same time, the space between the sealing cover 13 and the backing plate 14 can be used to install connection devices such as wires.

[0035] A base support plate is welded at the bottom of the installation sleeve 1, and installation holes are provided on its surface. The base support plate is fixed at the ground position through fixing parts such as bolts.

[0036] Refer to Appendix Figure 2 and Appendix Figure 9 As shown, multiple convex mirrors 2 are installed on the inner wall of the installation sleeve 1. Figure 9 As shown in the figure, it shows the distribution of the convex mirrors 2 on the inner wall of the installation sleeve 1. At the connection positions of the inlet pipe 15 and the discharge pipe 16 inside the installation sleeve 1, the assembly of the convex mirrors 2 is avoided, so as to prevent the convex mirrors 2 from blocking the introduction and discharge of water. A plurality of ultraviolet lamps 3 are annularly distributed between the two backing plates 14. The annular distribution of the plurality of ultraviolet lamps 3 improves the ultraviolet disinfection treatment of the water inside the installation sleeve 1, and the ultraviolet lamps 3 are electrically connected to the electric control device 11. A quartz tube 4 is sleeved outside the ultraviolet lamp 3, and a plurality of concave lens surfaces 41 are distributed on the quartz tube 4;

[0037] Refer to Appendix Figure 4 and Appendix Figure 7As shown, the quartz tube 4 is rotated to facilitate shaking off the attachments on the surface of the quartz tube 4, and at the same time, the irradiation surface of the ultraviolet lamp 3 from the surface of the quartz tube 4 is increased, and a rotating component 5 that drives multiple quartz tubes 4 to rotate is installed on one of the pads 14, and a wiping ring 6 is sleeved on the outside of the quartz tube 4, and multiple wiping rings 6 are connected to a metal ring 8 through a bracket plate 7, and a moving component 9 that drives the metal ring 8 to move along the length direction of the installation sleeve 1 is provided inside the installation sleeve 1.

[0038] The inlet pipe 15 is connected to the inner wall of the installation sleeve 1 at a place where the inlet pipe 15 is connected to a drainage groove 12. The rotating assembly 5 includes an annular plate 51 arranged at the pad 14. A gear ring 52 is arranged inside the annular plate 51. A gear 53 meshing with the gear ring 52 is installed at one end of the quartz tube 4. The outer ring of the annular plate 51 is provided with a plurality of concave arc segments 54, and the medium-pressure part of the concave arc segment 54 is provided with a water receiving groove 55. The drainage groove 12 is located on one side of the concave arc segment 54. A plurality of limiting rods 56 are installed on the back of the annular plate 51. An annular limiting groove 57 is provided on the pad 14, and the limiting rod 56 slides inside the annular limiting groove 57.

[0039] The two ends of the quartz tube 4 are respectively connected with waterproof pads 42, which are expansion plugs. The waterproof pads 42 are connected with terminal posts 43, one end of which is connected with the wire of the ultraviolet lamp 3, and the other end of which is connected with a connecting ring piece 44, which is electrically connected with the electric control device 11 through the wire. The pad 14 is provided with a plurality of holes 45, and the waterproof pads 42 are plugged in the holes 45.

[0040] The moving assembly 9 includes a gas extraction pump 91 mounted on the backing plate 14, and a piston tube 92 is connected to the gas extraction pump 91. The outer surface of the piston tube 92 is a mirror surface, and the piston tube 92 passes through the backing plate 14. A magnetic ring 93 is provided inside the piston tube 92, and the magnetic ring 93 is magnetically attracted to the metal ring 8. A deformable inner concave capsule 94 is provided on one side of the magnetic ring 93 close to the gas extraction pump 91.

[0041] When using the device in this solution, first fix the base plate at the bottom of the installation sleeve 1 to the ground by bolts or the like. Connect the inlet pipe 15 to the transition sleeve 17 through the flange surface and then connect it to the external pipeline. Then connect the discharge pipe 16 to the external pipeline through the flange. Water enters the inside of the installation sleeve 1 from the external pipeline through the transition sleeve 17 and the inlet pipe 15. Since the inner wall of the installation sleeve 1 is provided with a drainage groove 12, after the water flows from the drainage groove 12 into the water receiving groove 55, due to the design of the concave arc section 54 on the annular plate 51, when the water enters the water receiving groove 55, the gravity at the concave arc section 54 is greater than that of other parts. Then, under the action of gravity, the annular plate 51 is driven to rotate, so that the gear ring 52 can rotate the meshing gear 53, and the quartz tube 4 can rotate along the insertion position. At the same time, before the water enters, first adjust and set the electric control device 11 so that the ultraviolet lamp 3 emits ultraviolet light. The ultraviolet light is emitted to the concave lens surface 41 on the quartz tube 4, so that the ultraviolet light has the first divergence of light, which is convenient for the ultraviolet light to irradiate a larger water surface. Then the diverging light irradiates the convex mirror 2 and undergoes the second divergence, thereby increasing the receiving area of the light and the water. Through the first divergence of the concave lens surface 41 and the second divergence of the convex mirror 2, the ultraviolet light completely fills the entire inside of the installation sleeve 1, which is convenient for carrying out medium-pressure ultraviolet disinfection treatment on the water entering the inside of the installation sleeve. Then, the inside of the piston tube 92 is inflated through the gas extraction pump 91, so that the air pressure inside the piston tube 92 increases, which is convenient for pushing the magnetic attraction ring 93 to move forward along the inside of the piston tube 92. Since the magnetic attraction ring 93 and the metal ring 8 attract each other, the metal ring 9, the support plate 7 and the wiping ring 6 are driven to move, which is convenient for wiping the outside of the quartz tube 4. Similarly, the inside of the piston tube 92 is evacuated through the gas extraction pump 91, so that the concave inner capsule 94 is sucked out, and a negative pressure is formed inside the piston tube 92, which is convenient for pushing the magnetic attraction ring 93 to move backward along the inside of the piston tube 92. In this way, a cleaning effect can be achieved on the outside of the quartz tube 4, and the water quality is prevented from adhering to the outside of the quartz tube 4.
