Description

Technical Field

[0001] This invention relates to the field of ultraviolet sterilizers, specifically an ultraviolet sterilizer calibration device. Background Technology

[0002] An ultraviolet (UV) sterilizer is a device that uses a mercury lamp as its light source and the 253.7nm ultraviolet radiation emitted during the discharge of mercury vapor within the lamp tube as its main spectral line to disinfect drinking water. UV sterilizers are characterized by their ability to eliminate blind spots, provide excellent light conditions, low energy consumption, flexible and convenient installation and disassembly, and the absence of secondary pollution. Compared to chlorine sterilization, UV sterilizers do not require the addition of chemical agents, produce no secondary pollution, and eliminate the need for mixing equipment, significantly reducing operating costs. For drinking water, UV sterilizers are safe and will not cause adverse effects on the human body due to excessive chemical dosage. Compared to ozone sterilizers, UV sterilizers have advantages such as lower energy consumption, the absence of large mixing equipment, and the elimination of fishy odors, offering not only a better sensory experience but also lower operating costs.

[0003] In existing ultraviolet sterilizers, the inlet and outlet pipes are fixed to the connecting flanges of the connecting pipes using bolts and nuts via fixed flanges. However, the following problems still exist in the connection process of the existing inlet and outlet pipes to the connecting pipes:

[0004] Existing fixed flanges and connecting flanges all have the same number and position of mounting holes. When the inlet and outlet pipes are connected to the connecting pipes, the mounting holes on the fixed flanges and connecting flanges need to be aligned. However, the mounting bolts and nuts on the fixed flanges and connecting flanges need to be calibrated multiple times, which affects work efficiency. Therefore, it is necessary to develop a UV sterilizer calibration device for use in the existing UV sterilizer field. Summary of the Invention

[0005] To address the shortcomings of existing technologies, such as the need for multiple calibrations of mounting bolts and nuts on existing fixed flanges and connecting flanges, which affects work efficiency, this invention proposes a calibration device for ultraviolet sterilizers.

[0006] The technical solution adopted by this invention to solve its technical problem is as follows: an ultraviolet sterilizer calibration device, comprising a sterilization cylinder, an inlet pipe fixedly mounted on the sterilization cylinder, and an outlet pipe fixedly mounted on the sterilization cylinder. The interiors of both the inlet and outlet pipes are connected to the interior of the sterilization cylinder. A fixing flange is fixedly mounted at one end of each of the inlet and outlet pipes. A connecting flange is mounted on each fixing flange, and a connecting pipe is fixedly mounted on each connecting flange. Multiple mounting holes are arranged annularly on both the fixing and connecting flanges, located on the outer sides of the inlet, outlet, and connecting pipes, respectively. Fastening bolts are correspondingly mounted on the mounting holes on both the fixing and connecting flanges, and each fastening bolt is threaded. The flange has nuts and multiple guide arc blocks fixedly mounted on its surface. Multiple horizontal blocks are fixedly mounted on both the inlet and outlet pipes. A vertical block is fixedly mounted on one end of each horizontal block. The vertical block is located outside the flange. A traction rod is movably mounted on each vertical block. A calibration arc block is fixedly mounted on one end of each traction rod. The calibration arc block is located above the flange and between two guide arc blocks. A telescopic spring is mounted on each traction rod. The two ends of the telescopic spring are fixedly mounted to the calibration arc block and the vertical block, respectively. A traction port is provided through each traction rod. The traction port is located on one side of the vertical block. Multiple traction arc blocks are fixedly mounted on the surface of the connecting flange. Each traction arc block is provided with a slot.

[0007] Each vertical block is fixedly equipped with a fixed frame, and each fixed frame is symmetrically equipped with a sliding rod on its inner wall. Each sliding rod is movably equipped with a sliding block, and each sliding block is fixedly equipped with an operating rod. The operating rod is movably assembled with the traction port.

[0008] Both the inlet and outlet pipes are movably fitted with traction rings, which are located below the horizontal block. A connecting block is fixedly fitted between the two traction rings. Multiple mounting plates are fixedly fitted on each traction ring, and a fixing rod is fixedly fitted on each mounting plate. An operating plate is fixedly fitted at the bottom of each sliding block, and an assembly rod is fixedly fitted on each operating plate. An adjusting rod is movably fitted on each assembly rod, and the other end of the adjusting rod is movably fitted to the fixing rod.

[0009] A support frame is fixedly mounted on the disinfection cylinder, and a cylinder is fixedly mounted on the support frame. A piston rod is fixedly mounted on the output end of the cylinder. The piston rod moves through the support frame, and the bottom of the piston rod is fixedly mounted to the connecting block.

[0010] Preferably, the number of traction arc blocks is the same as the number of guide arc blocks.

[0011] Preferably, the fixed flange is provided with a sealing groove, which is located inside the mounting hole of the fixed flange, and a rubber sealing ring is fixedly installed at the bottom of the connecting flange, which is located inside the mounting hole of the connecting flange.

[0012] Preferably, when the connecting flange is fitted with the fixed flange along the guide arc block, the rubber sealing ring on the connecting flange is engaged with the sealing groove on the fixed flange, the arc surface of the connecting flange is fitted with the calibration arc block, and the calibration arc block is engaged with the corresponding groove on the traction arc block.

[0013] Preferably, the inner wall of the disinfection cylinder is fixedly equipped with multiple ultraviolet sterilization lamps, the bottom of the disinfection cylinder is fixedly equipped with a controller, a power cord is fixedly equipped between the disinfection cylinder and the controller, a pressure gauge is fixedly equipped on the controller, a switch button is fixedly equipped on the controller, a power indicator light is fixedly equipped on the controller, a lamp indicator light is fixedly equipped on the controller, and a timer is fixedly equipped on the controller.

[0014] Preferably, a drain pipe is fixedly installed at the bottom of the disinfection cylinder. The drain pipe is located on one side of the controller and its interior is connected to the interior of the disinfection cylinder. A valve is installed on the drain pipe.

[0015] The advantages of this invention are:

[0016] 1. This invention moves the connecting flange along the guide arc block, causing the connecting flange to fit against the fixed flange. The rubber sealing ring at the bottom of the connecting flange engages with the sealing groove on the fixed flange. Rotating the connecting pipe causes the rubber sealing ring on the connecting flange to rotate within the sealing groove on the fixed flange. Under the action of the traction arc block, the calibrating arc block moves the traction rod on the vertical block, while the telescopic spring contracts until the calibrating arc block engages with the groove on the traction arc block. At this point, the mounting holes on the fixed flange and the connecting flange coincide, facilitating the installation of fastening bolts and nuts on the connecting flange. This also facilitates the connection between the connecting pipe and the inlet and outlet pipes, improving calibration efficiency, avoiding fatigue caused by human visual inspection, and enhancing operational effectiveness.

[0017] 2. This invention activates the cylinder, causing the piston rod to move the connecting block upwards. The connecting block then moves the traction ring upwards. At this time, under the action of the adjusting rod, the operating rod moves on the traction port, the traction rod moves on the vertical block, and the telescopic spring contracts, causing the calibration arc block to move away from the slot on the traction arc block, facilitating the disassembly of pipes.

[0018] 3. This invention activates the cylinder, causing the piston rod to move the connecting block downwards. The connecting block then moves the traction ring downwards. At this time, under the action of the adjusting rod, the operating rod moves towards the pipeline at the traction port. The traction rod moves on the vertical block, and the telescopic spring is stretched, bringing the traction port closer to the vertical block. This helps the telescopic spring restore its elasticity, increases its service life, and reduces operating costs. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1

[0038] like Figures 1-4 As shown, it is a schematic diagram of a preferred embodiment of the ultraviolet sterilizer calibration device of the present invention. (Refer to...) Figure 1 and Figure 3 as well as Figure 4A UV sterilizer calibration device includes a sterilization cylinder 10. An inlet pipe 32 communicating with the interior of the sterilization cylinder 10 is fixedly mounted on the sterilization cylinder 10. An outlet pipe 33 communicating with the interior of the sterilization cylinder 10 is also fixedly mounted on the sterilization cylinder 10. A fixing flange 40 is fixedly mounted at one end of both the inlet pipe 32 and the outlet pipe 33. A connecting flange 43 is mounted on each fixing flange 40. A connecting pipe 42 is fixedly mounted on each connecting flange 43. Multiple mounting holes 50 are arranged annularly on both the fixing flange 40 and the connecting flange 43. The mounting holes 50 are located on the outer sides of the inlet pipe 32, the outlet pipe 33, and the connecting pipe 42, respectively. Fastening bolts 52 are correspondingly mounted on the mounting holes 50 on both the fixing flange 40 and the connecting flange 43. Each fastening bolt 52 is threaded. Nut 53 is provided. Multiple guide arc blocks 51 are fixedly mounted on the surface of the fixed flange 40. Multiple horizontal blocks 82 are fixedly mounted on both the inlet pipe 32 and the outlet pipe 33. A vertical block 83 is fixedly mounted on one end of each horizontal block 82, located outside the fixed flange 40. A traction rod 90 is movably mounted on each vertical block 83. A calibration arc block 91 is fixedly mounted on one end of each traction rod 90, located above the fixed flange 40 and between two guide arc blocks 51. A telescopic spring 92 is fixedly mounted between the calibration arc block 91 and the vertical block 83. The traction rod 90 is mounted inside the telescopic spring 92. A traction port 93 is provided through each traction rod 90, located on one side of the vertical block 83. The surface of the connecting flange 43 is... Multiple traction arc blocks 73 are fixedly assembled, each with a slot 80. The number of traction arc blocks 73 is the same as the number of guide arc blocks 51. A sealing groove 41 is provided on the fixed flange 40, located inside the mounting hole 50 of the fixed flange 40. A rubber sealing ring 81 is fixedly assembled at the bottom of the connecting flange 43, located inside the mounting hole 50 of the connecting flange 43. When the connecting flange 43 is fitted with the fixed flange 40 along the guide arc block 51, the rubber sealing ring 81 on the connecting flange 43 engages with the sealing groove 41 on the fixed flange 40. The arc surface of the connecting flange 43 fits with the calibration arc block 91, and the calibration arc block 91 engages with the slot 80 on the traction arc block 73. The connecting flange 43 moves along the guide arc block 51, causing the connecting flange 43 to fit against the fixed flange 40. The rubber sealing ring 81 at the bottom of the connecting flange 43 engages with the sealing groove 41 on the fixed flange 40. Rotating the connecting pipe 42 causes the rubber sealing ring 81 on the connecting flange 43 to rotate within the sealing groove 41 on the fixed flange 40. Under the action of the traction arc block 73, the calibration arc block 91 moves the traction rod 90 on the vertical block 83, while the telescopic spring 92 retracts until the calibration arc block 91 engages with the groove 80 on the traction arc block 73. At this point, the mounting hole 50 on the fixed flange 40 coincides with the mounting hole 50 on the connecting flange 43, facilitating the installation of fastening bolts 52 and nuts 53 on the connecting flange 43.The connection pipe 42 facilitates the connection between the inlet pipe 32 and the outlet pipe 33, making calibration easier, reducing eye strain, and improving operational efficiency.

[0039] Reference Figure 1 and Figure 2 Multiple ultraviolet sterilization lamps 71 are fixedly installed on the inner wall of the sterilization cylinder 10. A controller 11 is fixedly installed at the bottom of the sterilization cylinder 10. A power cord 12 is fixedly installed between the sterilization cylinder 10 and the controller 11. A pressure gauge 13 is fixedly installed on the controller 11. A switch button 20 is fixedly installed on the controller 11. A power indicator light 21 is fixedly installed on the controller 11. A lamp indicator light 22 is fixedly installed on the controller 11. A timer 23 is fixedly installed on the controller 11. The bottom of the sterilization cylinder 10 is fixedly equipped with a device that connects to the interior of the sterilization cylinder 10. A drain pipe 30 is connected to the controller 11. The drain pipe 30 is equipped with a valve 31. When the start switch button 20 is pressed, the power indicator light 21 lights up, and the lamp indicator lights 22 illuminate the various ultraviolet sterilization lamps 71 inside the sterilization cylinder 10. The pressure gauge 13 can display the pressure of the liquid flowing inside the sterilization cylinder 10. At the same time, the timer 23 can time the liquid flow time. When not in use, the valve 31 is opened, and the drain pipe 30 can discharge the accumulated liquid and impurities inside the sterilization cylinder 10.

[0040] Working principle: The connecting flange 43 is moved along the guide arc block 51, so that the connecting flange 43 fits against the fixed flange 40. The rubber sealing ring 81 at the bottom of the connecting flange 43 engages with the sealing groove 41 on the fixed flange 40. The connecting pipe 42 is rotated, so that the rubber sealing ring 81 on the connecting flange 43 rotates in the sealing groove 41 on the fixed flange 40. Under the action of the traction arc block 73, the calibration arc block 91 moves the traction rod 90 on the vertical block 83, while the telescopic spring 92 retracts until the calibration arc block 91 engages with the slot 80 on the traction arc block 73. At this time, the mounting hole 50 on the fixed flange 40 and the mounting hole 50 on the connecting flange 43 are engaged. The mounting holes 50 are aligned to facilitate the installation of fastening bolts 52 and nuts 53 on the connecting flange 43, and to facilitate the connection between the connecting pipe 42 and the inlet pipe 32 and outlet pipe 33 respectively. This facilitates calibration, avoids eye fatigue caused by human visual recognition, and improves the operating effect. The start switch button 20 illuminates the power indicator 21, and the lamp indicator 22 illuminates the corresponding ultraviolet sterilization lamps 71 inside the sterilization cylinder 10. The pressure gauge 13 displays the pressure of the liquid flowing inside the sterilization cylinder 10, and the timer 23 times the liquid flow time. When not in use, the valve 31 is opened, and the drain pipe 30 can discharge the accumulated liquid and impurities inside the sterilization cylinder 10.

[0041] Example 2

[0042] like Figures 1-6 As shown, this is a schematic diagram of a UV sterilizer calibration device according to another preferred embodiment of the present invention. Since the calibration arc block 91 engages with the slot 80 on the traction arc block 73, this makes disassembly cumbersome. Furthermore, the telescopic spring 92 is prone to deformation after prolonged use, affecting its lifespan and reducing the effectiveness of the calibration arc block 91. Therefore, based on embodiment 1, the device is improved. A fixing frame 96 is fixedly mounted on each vertical block 83, and slide rods 97 are symmetrically fixedly mounted on the inner walls of the fixing frames 96. Sliding blocks 98 are movably mounted on the two slide rods 97, and operating rods 99 that move at the traction port 93 are fixedly mounted on each sliding block 98. The inlet pipe 32 and outlet pipe 33 are also equipped with... The device is equipped with a traction ring 60, which is located below the horizontal block 82. A connecting block 61 is fixedly mounted between two traction rings 60. Multiple mounting plates 94 are fixedly mounted on each traction ring 60, and a fixing rod 95 is fixedly mounted on each mounting plate 94. An operating plate 84 is fixedly mounted on the bottom of each sliding block 98, and an assembly rod 85 is fixedly mounted on each operating plate 84. An adjusting rod 72 is movably mounted on each assembly rod 85, and the other end of the adjusting rod 72 is movably mounted to the fixing rod 95. A support frame 62 is fixedly mounted on the disinfection cylinder 10, and a cylinder 63 is fixedly mounted on the support frame 62. A piston rod 70 is fixedly mounted on the output end of the cylinder 63. The piston rod 70 movably passes through the support frame 62, and the bottom of the piston rod 70 is fixedly mounted to the connecting block 61.

[0043] Working principle: Starting cylinder 63 causes piston rod 70 to move connecting block 61 upwards, which in turn moves traction ring 60 upwards. At this time, under the action of adjusting rod 72, operating rod 99 moves on traction port 93, and traction rod 90 moves on vertical block 83. Telescopic spring 92 contracts, causing calibration arc block 91 to move away from the slot 80 on traction arc block 73, facilitating pipe disassembly. Simultaneously, starting cylinder 63 causes piston rod 70 to move connecting block 61 downwards, which in turn moves traction ring 60 downwards. At this time, under the action of adjusting rod 72, operating rod 99 moves towards the pipe on traction port 93, and traction rod 90 moves on vertical block 83. Telescopic spring 92 stretches, bringing traction port 93 closer to vertical block 83, helping telescopic spring 92 regain its elasticity, increasing its service life, and reducing operating costs.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
