Description

Technical Field

[0001] The invention relates to the technical field of water treatment, in particular to an explosion-proof spectroscopy TOC online monitor. Background Art

[0002] Today, when the chemical industry is very developed, there are many types of artificial synthetic organic matter in water bodies. One of the purposes of drinking water treatment is to remove artificial synthetic organic matter that is more harmful to the human body as much as possible. For the safety of drinking water quality, TOC, a comprehensive indicator of the total amount of reactive organic matter, is currently a very important water quality parameter. Real-time monitoring of the removal of this organic matter during the water treatment process is the guarantee for achieving automatic control of the entire water treatment process. By monitoring the changes in TOC, information feedback on the water treatment process can be quickly obtained, so that timely measures can be taken, such as changing the amount of flocculant added or replacing expired activated carbon, etc. Different water treatment processes can also be controlled for different pollution. However, the current detection method consumes energy and materials, and different detection methods must be adopted according to different situations. The process is complicated and it is difficult to ensure the accuracy of the detection. Summary of the invention

[0003] The object of the present invention is to provide an explosion-proof spectroscopy TOC online monitor to solve the problems raised in the above background technology.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: an explosion-proof spectroscopy TOC online monitor, comprising a base, a water pipe is arranged inside the base, the water pipe comprises an inlet half pipe and an outlet half pipe, a filter component is connected between the inlet half pipe and the outlet half pipe, the filter component filters the water body, a detection component is arranged on the outlet half pipe, the detection component detects the water body, a cleaning component is arranged outside the base, the cleaning component is installed on the outlet half pipe, and the cleaning component cleans the water pipe.

[0005] Furthermore, the filter assembly includes a servo motor, a filter wheel, and an air jet gun. The servo motor is arranged in a machine base, a driving gear is installed on the motor shaft of the servo motor, the filter wheel is rotatably arranged between the inlet half pipe and the outlet half pipe, three fan-shaped holes are evenly opened on the filter wheel, each of the fan-shaped holes is covered with a filter screen, a tooth groove is opened on the outer side of the filter wheel, and the tooth groove is meshed with the driving gear for transmission, and the air jet gun is arranged at one end of the filter wheel, and the air jet gun removes impurities on the filter screen;

[0006] The end of the inlet half pipe close to the filter wheel is provided with a fan-shaped hole that is the same as the fan-shaped hole, and the end of the inlet half pipe close to the filter wheel is provided with a sealing ring, the sealing ring is fan-shaped, and the sealing ring surrounds the outside of the fan-shaped hole. The arrangement of the end of the outlet half pipe close to the filter wheel is the same as that of the inlet half pipe. The water pump passes the water sample to be tested into the inlet half pipe, and the water sample is filtered through the filter screen. Impurities in the water sample adhere to the filter screen. As the impurities on the filter screen accumulate and increase, the water sample circulates poorly, resulting in a decrease in flow rate. The flow meter detects that the flow rate in the outlet half pipe becomes less, and drives the servo motor to rotate through the control system, and the servo motor then drives the pass through the driving gear The filter wheel rotates, and after the filter wheel rotates one-third of a circle, the fan-shaped holes that were originally connected to the fan-shaped holes rotate out, and the fan-shaped holes in other positions connect the inlet half pipe with the outlet half pipe. Since the contact between the filter wheel and the water pipe is relatively close, the water pipe will not be connected to the outside during the rotation of the filter wheel. Impurities are attached to the rotated filter screen, and the jet nozzle of the jet gun sprays pressurized gas to blow off the impurities on the filter screen. When the detector is continuously testing, it can ensure that the impurities in the water body are filtered out, and by intermittently replacing the filter screen, it can ensure that impurities will not block the flow of water samples, avoid the increase of internal water pressure in the water pipe and cause it to burst, thereby improving the filtration efficiency.

[0007] Furthermore, a short tube is vertically arranged in the middle of the outlet half-tube, and the diameter of the short tube is the same as the diameter of the outlet half-tube. The detection component includes a lifting platform, which is slidably installed in the short tube. A sealing ring is arranged on the lifting platform, and the sealing ring is used for sealing between the lifting platform and the short tube. A glass column is arranged at the bottom of the lifting platform, and a lifting mechanism and a triangulation mechanism are connected to the top of the lifting platform. When the lifting platform descends, the closer the glass column is to the spectrum receiving plate, the thinner the water sample flowing between the glass column and the spectrum receiving plate is. By detecting the distance between the glass column and the spectrum receiving plate, combined with the spectrum signal monitored by the spectrum receiving plate, continuous detection of organic matter in the water sample is achieved. Different from the light reaction or chemical organic decomposition detection method, the method in the present invention greatly reduces material loss, has high detection accuracy, and has a wide range of water body applications.

[0008] Furthermore, a spotlight is provided inside the glass column, and a bowl-shaped lens is provided on the outer layer of the spotlight. A spectrum receiving board is provided in the short tube, and the spectrum receiving board is provided directly below the glass column. The spotlight is connected to the spectrum receiving board and the control system circuit. A tritium-tungsten integrated light source is used in the spotlight to generate a continuous spectrum of 200-800 nanometers. The bowl-shaped lens is used to concentrate and reflect the light emitted by the spotlight to the same direction, thereby improving the utilization efficiency of the light source. The organic matter in the water body only absorbs part of the frequency band of the spectrum. The higher the content of organic matter, the more light of the corresponding frequency band in the spectrum is absorbed. The spectrum band that is not absorbed is received and analyzed by the spectrum receiving board, and then the content of total organic carbon in the water sample is inferred.

[0009] Furthermore, the lifting mechanism includes a screw, a lifting motor, an internal gear, and a gear nut. The screw is arranged above the lifting platform, the lifting motor is arranged in the machine base, the internal gear and the gear nut are rotatably installed in the machine base, the internal gear is arranged on the motor shaft of the lifting motor, the gear nut is threadedly connected to the screw, and gear teeth are provided on the outside of the gear nut. The gear teeth cooperate with the internal gear. The lifting motor drives the internal gear to rotate, and the internal gear drives the gear nut to rotate through the gear teeth. The gear nut rotates, the screw moves up and down, and then drives the lifting platform to move up and down.

[0010] Furthermore, the triangulation mechanism comprises a triangular plate and two guide rails, the two guide rails are installed in the base, a main foot and two auxiliary feet are arranged on the triangular plate, the two auxiliary feet are respectively slidably installed on the two guide rails, and the main foot is rotatably connected to the lifting platform;

[0011] The angle between the two guide rails is 120°, and the ends of the two guide rails that are close to each other point to the lifting platform. The two attached feet of the triangular width plate are symmetrically arranged on both sides of the main foot. The angle between the main foot and the attached feet is 120°. The main foot and the two attached feet are inscribed in the same circle. The main foot is precisely controlled to drive the lifting platform to maintain linear movement, making the movement of the lifting platform more stable, further improving the sealing effect between the lifting platform and the short pipe, and improving the accuracy of detection.

[0012] Furthermore, sliding resistors are provided in the two guide rails, sliding contacts are provided on the two attached feet, and the two groups of sliding resistors are connected to the control system circuit. The force of the main foot moving downward is decomposed into the force of the two attached feet moving. The upper attached foot moves a distance L1 to the lower right, and the lower attached foot moves a distance L2 to the lower left. The distance L3 of the main foot moving downward is the sum of L1 and L2. The sliding contacts on the two attached feet move in opposite directions on the sliding resistors, and the resistance values ​​of the two sliding resistors change in opposite directions. The control system decomposes any distance moved by the main foot into two displacements for detection based on the current signal flowing through the two sliding resistors. It can not only determine the moving direction of the main foot, but also realize the capture of continuous changes in displacement. Combined with the acquisition signal of the spectrum receiving board, accurate analysis can be performed to improve the online detection accuracy of the monitor.

[0013] Furthermore, the cleaning component includes a storage tube, which is connected to the outlet half pipe, and a front clamping block and a rear clamping block are arranged in the storage tube, a spring and a water-absorbing cotton are arranged between the front clamping block and the rear clamping block, one end of the storage tube is connected to a magnetic block container, a magnetic block chain is arranged in the magnetic block container, one end of the magnetic block chain passes through the rear clamping block and is connected to the front clamping block, and an electric motor, a retracting wheel and a clamping wheel are also arranged in the magnetic block container, the retracting wheel is installed on the rotating shaft of the electric motor, the clamping wheel is arranged above the retracting wheel, and the magnetic block chain is clamped between the clamping wheel and the retracting wheel Between the release wheels, after the test is completed, the electric motor drives the retracting and releasing wheels to rotate, and under the action of the clamping wheel, the magnetic block chain is pushed inward to the outlet half-pipe. Each magnetic block in the magnetic block chain is connected by a short rope. Each time a magnetic block is pushed out, it will be adsorbed with the previous magnetic block. Under the action of the spring, the distance between the front clamping block and the rear clamping block is pulled apart, and the absorbent cotton returns to a fluffy state. The front clamping block extends into the outlet half-pipe. As the amount of magnetic blocks pushed out increases, the front clamping block and the rear clamping block move in the outlet half-pipe, and the absorbent cotton cleans the residual water sample in the outlet half-pipe.

[0014] After cleaning to the end of the outlet half-tube, the electric motor drives the retracting and releasing wheel to reverse, and the magnetic block chain recycles the front clamp block and the rear clamp block. After the rear clamp block is stored in the storage tube, the front clamp block and the rear clamp block are close to squeeze out the water sample in the absorbent cotton. After each test, the outlet half-tube inside the instrument is cleaned to avoid residual water samples affecting the total organic carbon concentration of the water samples in the later stage, thereby ensuring the accuracy of the test data.

[0015] Furthermore, a water pump is provided on the inlet half pipe, and a flow meter is provided in the outlet half pipe.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0017] 1. By setting multiple filter screens on the filter wheel, the impurities on the filter screens accumulate and increase. When the water sample does not flow smoothly, the filter wheel rotates, and the fan-shaped holes originally connected to the fan-shaped holes rotate out, and the fan-shaped holes in other positions connect the inlet half pipe with the outlet half pipe. Impurities are attached to the rotated filter screens, and the jet gun blows the impurities on the filter screens off, which can ensure that the impurities in the water body are filtered out cleanly. By intermittently replacing the filter screens, it can be ensured that impurities will not block the flow of water samples, avoid the increase of internal water pressure in the water pipe and cause it to burst, and improve the filtration efficiency.

[0018] 2. By setting a triangular amplitude disk to drive the lifting platform to move and detect water samples, the main foot is accurately controlled to drive the lifting platform to maintain linear movement, so that the movement of the lifting platform is more stable and the detection accuracy is improved. The downward movement force of the main foot is decomposed into the movement force of the two attached feet. The downward movement distance of the main foot is the sum of the movement distances of the two attached feet. The sliding resistor is used to capture the displacement of the two attached feet. It can not only determine the movement direction of the main foot, but also realize the capture of continuous changes in displacement. Combined with the acquisition signal of the spectrum receiving board, accurate analysis is performed to improve the online detection accuracy of the monitor.

[0019] 3. By setting up a cleaning component, the outlet half pipe inside the instrument is cleaned after each test to avoid residual water samples affecting the total organic carbon concentration of subsequent water samples and ensure the accuracy of the test data.

[0040] Working principle of the present invention: During the use of the spectral TOC online monitor of the present invention, the water pump first passes the water sample to be detected into the inlet half pipe 201, and the water sample is filtered through the filter screen 4. Impurities in the water sample adhere to the filter screen 4. If the impurities on the filter screen 4 accumulate and the water sample does not flow smoothly, the flow meter detects that the flow in the outlet half pipe 202 decreases, and the servo motor 501 is driven to rotate through the control system. The servo motor 501 then drives the filter wheel 301 to rotate through the driving gear 502. The filter wheel 301 rotates one-third of a circle, and the fan-shaped holes originally connected to the fan-shaped holes rotate out, and the fan-shaped holes at other positions connect the inlet half pipe 201 with the outlet half pipe 202. Since the contact between the filter wheel 301 and the water pipe is relatively close, the water pipe will not be connected to the outside during the rotation of the filter wheel 301. Impurities adhere to the filter screen 4 that is rotated out, and the jet nozzle of the jet gun sprays pressurized gas to blow off the impurities on the filter screen 4.

[0041] The lifting motor 14 drives the internal gear 15 to rotate, and the internal gear 15 drives the gear nut 13 to rotate through the gear teeth. The gear nut 13 rotates, and the screw 12 moves up and down, thereby driving the lifting platform 10 to move up and down. When the lifting platform 10 descends, the closer the glass column 9 is to the spectrum receiving plate 6, the thinner the water sample flowing between the glass column 9 and the spectrum receiving plate 6 is. By detecting the distance between the glass column 9 and the spectrum receiving plate 6, the force of the main foot moving downward is decomposed into the force of the two attached feet moving. The upper attached foot moves a distance L1 to the lower right, and the lower attached foot moves a distance L2 to the lower left. The distance L3 of the main foot moving downward is the sum of L1 and L2. The sliding contacts on the two attached feet move in opposite directions on the sliding resistor, and the resistance values ​​of the two sliding resistors change in opposite directions. The control system decomposes any distance moved by the main foot into two displacements for detection according to the current signal flowing through the two sliding resistors, judges the moving direction of the main foot, and realizes the capture of continuous changes in displacement. Combined with the spectrum signal monitored by the spectrum receiving plate 6, continuous detection of organic matter in the water sample is realized.

[0042] After the detection is completed, the electric motor drives the retracting wheel 211 to rotate, and the magnetic block chain 20 is pushed into the outlet half pipe 202 under the action of the clamping wheel 212. Each magnetic block in the magnetic block chain 20 is connected by a short rope. Each time a magnetic block is pushed out, it will be adsorbed with the previous magnetic block. Under the action of the spring 23, the distance between the front clamping block 221 and the rear clamping block 222 is pulled apart, and the absorbent cotton 24 returns to a fluffy state. The front clamping block 221 extends into the outlet half pipe 202. 2, as the amount of magnetic blocks pushed out increases, the front clamp block 221 and the rear clamp block 222 move in the outlet half pipe 202, and the absorbent cotton 24 cleans the residual water sample in the outlet half pipe 202. After cleaning to the end of the outlet half pipe 202, the electric motor drives the retracting wheel 211 to reverse, and the magnetic block chain 20 recycles the front clamp block 221 and the rear clamp block 222. After the rear clamp block 222 is received in the storage tube 18, the front clamp block 221 and the rear clamp block 222 are close to each other to squeeze out the water sample in the absorbent cotton 24.
