Description

Technical Field

[0001] The present invention relates to the technical field of water treatment, in particular to an over-flow ultraviolet sterilization water treatment system. Background Art

[0002] Currently, existing over-the-counter UV water treatment equipment primarily uses static filters or simple settling chambers for initial impurity removal. UV lamps typically irradiate from a single source, leaving water flowing in a straight line through the pipes. These systems lack flow direction guidance and flow rate regulation. These existing systems suffer from the following shortcomings: First, sterilization effectiveness fluctuates significantly with varying flow rates. Excessively fast flow rates result in insufficient UV exposure time, resulting in incomplete sterilization; while excessively slow flow rates waste energy and reduce efficiency. Second, impurity separation is poor, with sand and gravel easily deposited on the filter, clogging the waterway. Maintenance is frequent, and dynamic sludge removal is impossible. Third, there is no real-time monitoring mechanism for effluent water quality, forcing users to rely on experience or scheduled maintenance to estimate equipment status, lacking accurate and effective data feedback. Furthermore, traditional UV lamps irradiate in a single direction, creating significant sterilization blind spots, which impacts overall sterilization uniformity and thoroughness. Finally, the filtration system cannot dynamically adjust filtration resistance based on water quality changes, resulting in inflexible adaptation of filtration effectiveness and water flow to varying water quality conditions and low efficiency.

A plurality of guide sliding plates 127 are fixedly mounted in a circular array on the circumferential surface of the baffle 129. The guide sliding plates 127 allow the baffle 129 to slide and engage with the inner wall of the sterilized transparent glass tube 109. An adjustable flow guide 132 is rotatably engaged with the inner wall of the baffle 129. The adjustable flow guide 132 and the baffle 129 are respectively provided with a plurality of dynamic adjustable flow guide ports 133 and fixed adjustable flow guide ports 128 of the same number.

An adjustable ring 121 is rotatably and slidably mounted on the outer surface of the sterilized transparent glass tube 109. The adjustable ring 121 and the permanent magnet 131 can engage magnetically.

[0024] The pretreatment unit includes a filter chamber 104, with a central pipe 108 inserted into the axial center of the filter chamber 104. The central pipe 108 has multiple separation inlets 116 on its circumferential surface located within the filter chamber 104. An electromagnet 118 is fixed overhead below one end of the central pipe 108 within the filter chamber 104.

The plugging cone 117 contacts the central pipe 108, and a spring 120 is fixedly mounted between the plugging cone 117 and the electromagnet 118. The bottom end of the filter chamber 104 is fixedly connected to a sedimentation slag discharge hopper 105, and the bottom end of the sedimentation slag discharge hopper 105 is fixedly connected to an electric slag discharge valve 106. An ultrasonic rangefinder 114 is provided on the top of the filter chamber 104, and the ultrasonic rangefinder 114 is used to monitor the height of the sediment inside the sedimentation slag discharge hopper 105; a filter screen 115 is also provided inside the central pipe 108, and the central pipe 108 is connected to the inside of the sterilization transparent glass tube 109. A tangential pipe 107 is also fixedly provided on the circumferential surface of the filter chamber 104 along its own tangential direction, and a water inlet pipe 102 is fixedly installed on the tangential pipe 107.

[0025] The detection unit includes an outlet pipe 103 fixedly connected to the end of a sterilized transparent glass tube 109 away from the central pipe 108. A derotator 111 is fixedly mounted on the inner wall of the outlet pipe 103, near the sterilized transparent glass tube 109. The derotator 111 is used to rectify and derotate the fluid entering the outlet pipe 103. A laser emitter 110 and a light intensity sensor 112 are fixedly mounted on the outer surface of the outlet pipe 103. The laser emitter 110 and the light intensity sensor 112 are symmetrically arranged. The light emitted by the laser emitter 110 is arranged to intersect the axis of the outlet pipe 103. A camera 113 is also overhead and fixed on the outer surface of the outlet pipe 103. The lens axis of the camera 113 intersects and is perpendicular to the light emitted by the laser emitter 110 and the axis of the outlet pipe 103. The sterilization transparent glass tube 109, the detection part and the pretreatment part are covered with a light-shielding shell 101, wherein the water outlet pipe 103 and the water inlet pipe 102 extend to the outside of the light-shielding shell 101, and the water inlet pipe 102 and the water outlet pipe 103 are both equipped with flanges.

[0026] The working principle of the water treatment system for over-flow ultraviolet sterilization disclosed in the present invention is as follows: the water inlet pipe 102 and the water outlet pipe 103 are installed in series in the water channel to be sterilized, so that the direction of water flow is from the water inlet pipe 102 to the water outlet pipe 103. After water enters the water inlet pipe 102 (there is a water pump or other power to force the water to flow into the water inlet pipe 102), it will rotate along the inner wall of the filter chamber 104 through the tangential pipe 107. At this time, the sand and gravel in the water have a greater density than water, so they will rotate along the inner wall of the filter chamber 104, while the water has a lower density than the sand and gravel, and under the action of the pressure difference, It will enter the central pipe 108 through the separation inlet 116, and then enter the sterilized transparent glass tube 109 through further filtration of the filter screen 115. During this process, the sand and gravel inside the filter chamber 104 will continue to rotate along the inner wall of the filter chamber 104, and gradually sink into the sedimentation slag discharge bucket 105 under the action of gravity. The ultrasonic rangefinder 114 continuously monitors the thickness of the sand and gravel deposits inside the sedimentation slag discharge bucket 105. If it exceeds the standard, the electric slag discharge valve 106 will be opened, and then the sand and gravel will be discharged (the pressure will tend to cause the water and sand inside the filter chamber 104 to be sprayed out from the electric slag discharge valve 106). After the filtered water enters the sterilization transparent glass tube 109, it first passes through the adaptive component, and then passes through the gap between the inner wall of the sterilization transparent glass tube 109 and the outer surface of the internal ultraviolet lamp 124. During this process, the internal ultraviolet lamp 124 and all the outer wall ultraviolet lamps 123 are started, and the internal ultraviolet lamp 124 and the outer wall ultraviolet lamp 123 generate ultraviolet rays to irradiate and sterilize the water between the sterilization transparent glass tube 109 and the internal ultraviolet lamp 124 (according to the type of bacteria in the water, the wavelength of the ultraviolet rays emitted by the internal ultraviolet lamp 124 and the outer wall ultraviolet lamp 123 is adjusted (preset)). If the water flow rate increases, the adaptive component will be subject to increased water resistance, thereby driving the mounting plate 126 to squeeze the spiral guide plate 125, thereby shortening the pitch of the spiral guide plate 125. At this time, the pitch of the spiral guide plate 125 between the internal ultraviolet lamp tube 124 and the sterilization transparent glass tube 109 will also be reduced, which will cause the flow path of the water between the internal ultraviolet lamp tube 124 and the sterilization transparent glass tube 109 to be extended, and the water flow rate to be reduced. At the same time, the water between the internal ultraviolet lamp tube 124 and the sterilization transparent glass tube 109 rotates along the spiral guide plate 125, so smaller impurities in the water will also be affected by centrifugal force. Combined with the reduction in the pitch of the spiral guide plate 125, this will cause the water flow rate to increase, making it easier to drive impurities in the water to the inner wall of the sterilization transparent glass tube 109, allowing the light of the internal ultraviolet lamp tube 124 to pass through the water more easily, thereby improving the sterilization effect on the water.If there are fewer fine sand and gravel in the water, the electromagnet 118 can be started at this time. The electromagnet 118 generates magnetic force to attract the blocking cone head 117, so that the blocking cone head 117 is separated from the central pipe 108, thereby allowing more water to enter the central pipe 108 and increasing the flow rate of the water. Moreover, since there are no fine sand and gravel, large sand and gravel are easier to separate in the filter chamber 104, so there is no need to seal the blocking cone head 117.

[0027] After the water passes through the adaptive component, the water flow will enter the adjustment guide cover 132 in the spoiler 129, and then flow out through the dynamic adjustment guide port 133 and the fixed adjustment guide port 128. If you want to condition the resistance of the adaptive component to water, you can adjust it by changing the degree of staggering between the dynamic adjustment guide port 133 and the fixed adjustment guide port 128. The adjustment ring 121 is rotated manually or by motor drive (first start the electromagnetic coil inside the adjustment ring 121, and the electromagnetic coil is embedded inside the adjustment ring 121). The adjustment ring 121 drives the permanent magnet 131 to rotate with it through magnetic force. The permanent magnet 131 drives the adjustment guide cover 132 to rotate through the permanent magnet bracket 130, and then the dynamic adjustment guide port 133 and the fixed adjustment guide port 128 will be staggered, thereby changing the resistance of the adaptive component to water, which is used to adjust the pitch change of the spiral guide plate 125 under the same water flow rate.

[0028] When the sterilized water passes through the outlet pipe 103 (the distance between the laser emitter 110 and the sterilization transparent glass tube 109 is not as shown in the figure, the axial length of the outlet pipe 103 on the way is shortened), the vortex caused by the spiral guide plate 125 is eliminated by the de-swirl device 111, and then the water will pass through the light emitted by the laser emitter 110. If there are impurities in the water, they will block the light emitted by the laser emitter 110. At this time, the light intensity received by the light intensity sensor 112 will be weakened. At the same time, if the light hits sand and gravel, It will cause reflections on the surface of the sand and stones. At this time, the camera 113 will capture the light carefully to record the changes in the sand and stones in the water. If the impurities in the water exceed the standard, it is necessary to increase the flow rate of water entering the water inlet pipe 102, thereby increasing the degree of filtration of sand and stones at the filter chamber 104, and replace the filter screen 115 at the same time. The adaptive component can also be adjusted to change the pitch of the spiral guide plate 125. By slowing down the flow rate, the internal ultraviolet lamp tube 124 and the outer wall ultraviolet lamp tube 123 can increase the irradiation and sterilization time of the water to improve the sterilization effect.
