Description

Technical Field

[0001] The invention relates to the technical field of disinfection equipment, in particular to a medium-pressure ultraviolet disinfection water treatment device. Background Art

[0002] The water in daily drinking water, swimming pools, waterscape pools, etc. contains various bacteria, viruses, and molds. In order to disinfect the water quality, disinfectants are added, or ultraviolet sterilization treatments are performed. Among them, ultraviolet radiation has the advantages of no pollution, no residue, safety and reliability, and is widely used.

[0003] Ultraviolet disinfectors are divided into low-pressure ultraviolet and high-pressure ultraviolet. Low-pressure ultraviolet lamps only output single-wave ultraviolet rays with wavelengths of 185nm and 254nm. The pressure of the inert gas filled in the lamp is about 0.013MPA lower than the atmospheric pressure, forming a negative pressure state. 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. It can radiate multi-wavelength ultraviolet rays with a wider range. Therefore, it is more suitable to use medium-pressure ultraviolet rays for disinfection of swimming pools. After irradiation with medium-pressure ultraviolet rays, the DNA chains of bacteria in the water are destroyed, thereby achieving the effect of rapid disinfection.

[0004] The existing medium-pressure ultraviolet disinfection equipment has an ultraviolet disinfection lamp, an inlet pipe and a discharge pipe installed in its pipe sleeve. Water is introduced into the pipe sleeve from the inlet pipe, irradiated by the ultraviolet disinfection lamp to achieve the disinfection effect, and then 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 by the inlet pipe is much larger than that in the sleeve, the water close to the lamp tube position is disinfected first. The killed bacteria remaining in the disinfected water will hinder the upper water from fully receiving the ultraviolet lamp irradiation. At the same time, in the practical process, the killed algae and bacteria in the water 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 disinfection water treatment device. Summary of the invention

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figure 1-Figure 13The present invention provides a technical solution: a medium-pressure ultraviolet disinfection water treatment device, comprising a mounting sleeve 1, the mounting sleeve 1 is a through-tube structure, and its two end faces are flange mounting faces, and an electric control device 11 is mounted on the mounting sleeve 1, and 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. The timer can record the working time and remind when the lamp needs to be replaced. The lamp online intensity detection device adopts a wet probe, and an alarm is issued when the actual 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 failing due to water leakage in the reactor. Sealing covers 13 are respectively assembled at both ends of the mounting sleeve 1, and a pad 14 is connected between the sealing cover 13 and the sleeve. An inlet pipe 15 is installed on one side of the mounting sleeve 1, and a discharge pipe 16 is installed on the other side of the mounting 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 to a transition sleeve 17, and a spherical section is provided on the transition sleeve 17. The gasket 14 here is installed on the mounting sleeve 1 through the flange mounting surface, and then the sealing cover 13 is installed on the outside of the gasket 14 through fixing connectors such as pins. The sealing cover 13 plays a sealing and protective role on the gasket 14. At the same time, the space between the sealing cover 13 and the gasket 14 can be used to install connecting devices such as wires.

[0035] A base support plate is welded at the bottom of the installation sleeve 1, and a mounting hole is opened on the surface of the base support plate. The base support plate is fixed to the ground by bolts and other fixing parts.

[0036] Reference Figure 2 and attached Fig. 9 As shown, the inner wall of the mounting sleeve 1 is equipped with multiple sets of convex mirrors 2. Fig. 9 The figure shows the distribution of the convex mirror 2 on the inner wall of the installation sleeve 1. The assembly of the convex mirror 2 is avoided at the connection position with the introduction pipe 15 and the discharge pipe 16 inside the installation sleeve 1, thereby avoiding the convex mirror 2 blocking the introduction and discharge of water. A plurality of ultraviolet lamps 3 are distributed in a ring shape between the two pads 14. The plurality of ultraviolet lamps 3 are distributed in a ring shape, which improves the ultraviolet disinfection treatment of the water inside the installation sleeve 1. The ultraviolet lamp 3 is electrically connected to the electric control device 11. The ultraviolet lamp 3 is covered with a quartz tube 4 outside, and a plurality of concave lens surfaces 41 are distributed on the quartz tube 4.

[0037] Reference Figure 4 and attached 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, etc., connect the inlet pipe 15 to the transition sleeve 17 through the flange surface, and then connect it to the external pipeline, and then connect the discharge pipe 16 to the external pipeline through the flange. Water enters the inlet pipe 15 from the external pipeline through the transition sleeve 17 and enters the interior of the installation sleeve 1. 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 concave arc on the annular plate 51, the water flows into the water receiving groove 55. According to the design of the segment 54, after water enters the water receiving groove 55, the gravity at the concave arc segment 54 is greater than that at other parts, and then the annular plate 51 is driven to rotate under the action of gravity, so that the gear ring 52 can rotate the meshing gear 53, so that the quartz tube 4 rotates along the plug-in position. At the same time, before the water enters, the electronic control device 11 is first adjusted and set, so that the ultraviolet lamp 3 emits ultraviolet light, and the ultraviolet light is emitted to the concave lens surface 41 on the quartz tube 4, so that the ultraviolet light has the first light divergence, which is convenient for ultraviolet light irradiation. The divergent light is then irradiated to the convex mirror 2 for a 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 is completely filled in the entire installation sleeve 1, which is convenient for the water entering the installation sleeve to be disinfected by medium-pressure ultraviolet light. Then, the piston tube 92 is inflated by the gas extraction pump 91, so that the air pressure inside the piston tube 92 is increased, which is convenient for pushing the magnetic attraction ring 93 along the piston tube 92. The inside moves forward, and due to the attraction between the magnetic ring 93 and the metal ring 8, the metal ring 9, the bracket plate 7 and the wiping ring 6 are driven to move, so as to facilitate the wiping effect on the outside of the quartz tube 4. Similarly, the gas extraction pump 91 is used to evacuate the inside of the piston tube 92, so as to suck out the inner concave capsule 94, so that a negative pressure is formed inside the piston tube 92, which is convenient for pushing the magnetic ring 93 to move backward along the inside of the piston tube 92, so that the outside of the quartz tube 4 can be cleaned, avoiding the water quality from docking on the outside of the quartz tube 4.
