Description

Technical Field

[0001] The invention belongs to the technical field of heavy metal detection, and in particular relates to a heavy metal detection device for industrial waste water. Background Art

[0002] With the continuous progress and development of industry, industrial wastewater has become a problem that needs to be solved urgently. For example, a large amount of industrial wastewater will be generated in the process of industrial production such as metallurgy, machinery manufacturing, and chemical production. These industrial wastewaters contain heavy metals. Since heavy metals cannot be degraded, over time, heavy metals will be enriched in animals and plants, soil and water. When people use animals and plants containing a large amount of heavy metals for a long time or drink water containing heavy metals for a long time, heavy metal poisoning will occur in the human body, causing harm to human health. Therefore, it is a necessary measure to detect the heavy metal content through industrial wastewater heavy metal detection devices.

[0004] In the above-mentioned patent document, by providing a lower box and an upper box, the detector can be carried safely and conveniently and the detector is protected. By providing a power supply in the box, the detector can be connected to the power supply to work, which greatly extends the working time. However, the industrial wastewater heavy metal rapid detection device announced above does not have a self-test function when it encounters a collision during the process of carrying.

[0042] The present invention is further described below in conjunction with specific embodiments.

[0043] In order to solve the problem that the industrial wastewater heavy metal rapid detection device in the prior art does not have a self-detection function when it encounters a collision during carrying, such as Figure 1 - Fig.17 As shown:

[0044] A heavy metal detection device for industrial wastewater comprises a lower box body 1 and an upper box cover 2 rotatably arranged on the lower box body 1, the upper box cover 2 can realize an opening and closing effect on the lower box body 1, when the heavy metal detection device for industrial wastewater is carried out, the upper box cover 2 is flipped until the upper box cover 2 and the lower box body 1 are closed, thereby protecting the components inside the lower box body 1, the interior of the lower box body 1 is respectively provided with a controller 3, a vibration sensor 4, an alarm 5, a preparation tank 6, a medicine bottle 7 and a detector 8, and the interior of the lower box body 1 is also respectively provided with a protective shell 9, a telescopic assembly 20, a first battery 50, a second battery 60, a transposition assembly 70, a first compression assembly 90 and a second compression assembly 80, a calibration tank 10 is threadedly connected to the protective shell 9, and an electrode 30 and a plug 40 are clamped and arranged on the telescopic assembly 20, when the heavy metal detection device for industrial wastewater is carried out, the protective shell 9 can limit and protect the electrode 30, thereby reducing the damage caused by shaking of the electrode 30.

[0045] When the staff carries the industrial wastewater heavy metal detection device out, they first flip the upper box cover 2 until the upper box cover 2 and the lower box body 1 are closed. During the process of flipping and closing the upper box cover 2, pressure is applied to the first compression assembly 90 and the second compression assembly 80, so that the first compression assembly 90 and the second compression assembly 80 compress the gas, and the compressed gas is temporarily stored in the lower box body 1. During the carrying process, if the upper box cover 2 or the lower box body 1 is bumped or hit, the vibration sensor 4 will monitor the vibration. When the vibration threshold is exceeded, the controller 3 controls the first compression assembly 90 to release the compressed gas temporarily stored in the lower box body 1. The released compressed gas enters the interior of the telescopic assembly 20 and drives the telescopic assembly 20 to extend in two opposite directions, so that the plug 40 is inserted into the detector 8, and the electrodes 30 in the opposite direction are inserted into the interior of the calibration tank 10. Due to the calibration tank 10 The interior is filled with a pre-configured zero-point solution, so the detection end of the electrode 30 will be immersed in the zero-point solution. Since the detector 8 has a built-in battery and can provide stable power output, when the plug 40 is inserted into the detector 8 and the electrode 30 in the opposite direction is inserted into the calibration tank 10, the detector 8 and the electrode 30 form a passage and transmit appropriate power to the electrode 30. The electrode 30 is calibrated multiple times, and the data is recorded for comparison to determine whether the electrode 30 is damaged during the bump or collision process. Under the premise that the battery inside the detector 8 can supply power stably, if the numerical difference after multiple tests of the electrode 30 is within the error range, it is determined that the electrode 30 is not damaged. If the numerical difference after multiple tests of the electrode 30 is outside the error range, it is determined that the electrode 30 is damaged. At the same time, the alarm 5 sounds an alarm to remind the operator that the electrode 30 is damaged due to bumps or collisions.

[0046] Furthermore, the first battery 50 and the second battery 60 are electrically connected to the controller 3, and the controller 3 can monitor in real time whether the first battery 50 and the second battery 60 are in a stable power supply state. When it is determined through the collected data that the calibration error of the electrode 30 is large, there is another situation at this time, that is, the electrode 30 is not damaged, but the battery inside the detector 8 cannot provide stable power supply after bumps or collisions, which leads to a large calibration error of the electrode 30. At this time, the controller 3 controls the second compression component 80 to release the compressed gas temporarily stored in the lower box 1, and the released compressed gas will enter the transposition component 70. The transposition component 70 first drives the connection terminal of the detector 8 to be electrically connected to the first battery 50. Under the coordinated setting of the built-in program control and circuit of the detector 8, when the first battery 50 forms a path with the detector 8 and the electrode 30, the built-in battery of the detector 8 does not supply power. At this time, the first battery 50 provides stable power to the detector 8 and the electrode 30. When the second battery 60 is used to test the electrode 30, it is consistent with the above-mentioned test operation.

[0047] The lower box body 1 includes a lower box body body 11, and the lower box body body 11 is respectively provided with a first mounting groove 12, a second mounting groove 13, a third mounting groove 14, a fourth mounting groove 15 and a wire groove 16, the second mounting groove 13, the third mounting groove 14, and the fourth mounting groove 15 are connected, and the first mounting groove 12 and the second mounting groove 13 are connected through the wire groove 16, and the interior of the lower box body 11 is also provided with an airway 17, an airway 2 18, an airway 3 19, and an airway 4 20. 9. Compression chamber 1 120 and compression chamber 2 130, air duct 1 17 is connected with compression chamber 1 120, compression chamber 2 130 is connected with air duct 2 18 and air duct 3 19 respectively, and one-way air intake valve 1 200 and one-way air intake valve 2 100 are fixedly installed on the side walls of the lower box body 11 respectively, one-way air intake valve 1 200 is connected with compression chamber 1 120, and one-way air intake valve 2 100 is connected with compression chamber 2 130.

[0048] The upper box cover 2 includes an upper box cover body 21 rotatably mounted on the lower box body 11, and an arc-shaped pressure plate 1 22 and an arc-shaped pressure plate 2 23 are fixedly mounted on the inner side walls of the upper box cover body 21, respectively. When the upper box cover 2 and the lower box body 1 are in a closed state, the arc-shaped pressure plate 1 22 applies pressure to the second compression assembly 80, causing the second compression assembly 80 to retract into the interior of the compression chamber 2 130 and compress the gas inside the compression chamber 2 130, while the arc-shaped pressure plate 2 23 applies pressure to the first compression assembly 90, causing the first compression assembly 90 to retract into the interior of the compression chamber 1 120 and compress the gas inside the compression chamber 1 120.

[0049] The detector 8 includes a detector body 81 placed in the second installation groove 13. A socket 82 is provided on the side wall of the detector body 81 close to the plug 40. The plug 40 and the socket 82 are concentrically arranged. When the plug 40 is inserted into the socket 82, electric energy transmission can be realized. A moving contact 83 is slidably installed on the transposition component 70. The moving contact 83 is electrically connected to the detector body 81 through an electric wire 84. The electric wire 84 is laid in the inner cavity of the wire groove 16 and contacts the first battery 50 or the second battery 60 through the moving contact 83, thereby transmitting the electric energy of the first battery 50 or the second battery 60 to the detector body 81 through the moving contact 83 and the electric wire 84 for use during detection.

[0050] The calibration tank 10 includes a tank body 101 threadedly connected to the inside of the protective shell 9, a slideway 102 and a liquid storage bin 105 are respectively provided inside the tank body 101, the slideway 102 and the liquid storage bin 105 are connected, a fixed sleeve 103 is fixedly installed in the inner cavity of the slideway 102, a sliding sleeve 104 is slidably installed on the side wall of the inner ring of the fixed sleeve 103, a fixed block 106 is fixedly installed at the connection between the slideway 102 and the liquid storage bin 105, a conical block 107 is slidably installed on the fixed block 106, and the conical block 107 is slidably installed. The side wall of the tank body 101 is elastically connected to the side wall of the inner cavity of the slide 102 by a first spring 108, a liquid inlet 109 is fixedly installed on the side wall of the end of the tank body 101 away from the conical block 107, and the liquid inlet 109 is connected to the liquid storage tank 105. An air channel 4 1020 is also opened on the side wall of the end of the tank body 101 away from the conical block 107, and a one-way air intake valve 3 1030 is fixedly installed inside the air channel 4 1020, and the one-way air intake valve 3 1030 is connected to the air channel 17 through an air pipe 1040.

[0051] When the upper box cover 2 and the lower box body 1 are in a closed state, the arc-shaped pressure plate 22 applies pressure to the first compression assembly 90, and compressed gas is generated inside the compression chamber 120. When the vibration sensor 4 detects that the vibration of the industrial wastewater heavy metal detection device exceeds the set threshold, the compressed gas inside the compression chamber 120 is released. The released compressed gas enters the liquid storage tank 105 through the airway 17, the air pipe 1040 and the one-way air inlet valve 3 1030 to pressurize the zero-point solution in the liquid storage tank 105. In addition, a part of the compressed gas enters the interior of the telescopic assembly 20. The telescopic assembly 20 is driven to extend in two opposite directions, so that the plug 40 is inserted into the socket 82, and the electrode 30 in the opposite direction is inserted into the internal sliding sleeve 104 of the calibration tank 10, and drives the sliding sleeve 104 to slide on the fixed sleeve 103. When the sliding sleeve 104 slides, it pushes the conical block 107 to slide on the fixed block 106, so that a gap appears between the conical block 107 and the fixed block 106, and then the zero-point solution in the liquid storage tank 105 enters the interior of the slideway 102 through the gap between the conical block 107 and the fixed block 106 under the action of air pressure and immerses the sliding sleeve 104.

[0052] The sliding sleeve 104 includes a sleeve body 1041. A plurality of through holes 1042 are formed on the peripheral side wall of the sleeve body 1041. No through holes 1042 are formed on the side wall of the sleeve body 1041 opposite to the conical block 107. In the initial state, Figure 8 As shown, the sleeve body 1041 is flush with the fixed sleeve 103, and the through hole 1042 is blocked by the side wall of the fixed sleeve 103. Since the through hole 1042 is not provided on the side wall of the sleeve body 1041 opposite to the conical block 107, in the initial state, the zero-point solution inside the liquid storage tank 105 will not enter the interior of the sleeve body 1041 through the through hole 1042. When the electrode 30 pushes the sleeve body 1041 to slide on the fixed sleeve 103 to the state where the through hole 1042 is not blocked by the side wall of the fixed sleeve 103, the zero-point solution inside the liquid storage tank 105 will enter the interior of the sleeve body 1041 through the through hole 1042 and immerse the detection end of the electrode 30 for subsequent calibration testing of the electrode 30.

[0053] The plug 40 includes a plug pin 401 that is snap-fitted to the telescopic assembly 20 . The plug pin 401 is electrically connected to the electrode 30 via a wire 402 . Electric energy is transmitted to the electrode 30 via the plug pin 401 and the wire 402 .

[0054] The telescopic assembly 20 includes a pair of mounting frames 201 fixedly mounted on the inner cavity side wall of the fourth mounting groove 15, a sleeve 202 is fixedly mounted on the two mounting frames 201, a hollow mounting block 203 is fixedly mounted inside the sleeve 202, a pair of ejector rods 204 are also slidably mounted inside the sleeve 202, the two ejector rods 204 are arranged in opposite directions, the two ejector rods 204 are elastically connected to the hollow mounting block 203 respectively through a second spring 205, a clamping piece 206 is fixedly mounted at the distal end of the two ejector rods 204, the two clamping pieces 206 are respectively clamped with the pin 401 and the electrode 30, an air pipe 207 is connected to the outer wall of one side of the sleeve 202, the air pipe 207 is connected to the compression chamber 1 120, and a pair of ejector rods 204 are connected to the top surface of the sleeve 202. Pressure relief valve 208, when the electrode 30 is calibrated and tested, the compressed gas in compression chamber 120 enters the interior of sleeve 202 through air pipe 207, pushing the two push rods 204 to move in two opposite directions. During the movement, the two push rods 204 respectively insert the pin 401 into the inner cavity of the socket 82 through the snap-fit ​​piece 206, and insert the electrode 30 into the sliding sleeve 104, for subsequent calibration test of the electrode 30. When the calibration test is completed, the controller 3 controls the pressure relief valve 208 to open, releases the gas inside the sleeve 202, and then under the elastic force of the second spring 205, the two push rods 204 respectively pull out the pin 401 from the interior of the socket 82 through the snap-fit ​​piece 206, and pull out the electrode 30 from the sliding sleeve 104.

[0055] The first compression assembly 90 includes a compression plate 902 slidably mounted in the inner cavity of the compression chamber 120, the compression plate 902 is elastically connected to the side wall of the inner cavity of the compression chamber 120 by a third spring 903, an arc-shaped slide plate 901 is fixedly mounted on the top surface of the compression plate 902, an electronic gas valve 904 is arranged at the connection point between the air pipe 207 and the compression chamber 120, and an electronic gas valve 905 is arranged at the connection point between the airway 17 and the compression chamber 120, when the arc-shaped pressure plate 22 applies pressure to the arc-shaped slide plate 901 and the compression plate 902, the arc-shaped slide plate 901 and the compression plate 902 slide toward the inside of the compression chamber 120 and compress the gas inside the compression chamber 120 for subsequent use, and the setting of the one-way air inlet valve 200 allows the external gas to enter the interior of the compression chamber 120 for compression.

[0056] Specifically, when the staff carries the industrial wastewater heavy metal detection device out, they first flip the upper box cover 2 until the upper box cover 2 and the lower box body 1 are closed. During the process of flipping and closing the upper box cover 2, the arc pressure plate 22 applies pressure to the arc slide plate 901 and the compression plate 902, so that the compression plate 902 compresses the gas inside the compression chamber 120, and the compressed gas is temporarily stored in the compression chamber 120. During the carrying process, if the upper box cover 2 or the lower box body 1 is bumped or hit, the vibration sensor 4 will monitor the vibration. When the vibration threshold is exceeded, the controller 3 controls the electronic gas valve 2 905 to open, and the compressed gas temporarily stored in the compression chamber 120 enters the liquid storage tank 105 through the airway 17, the air pipe 1040, the one-way air inlet valve 3 1030 and the airway 4 1020, and the zero-point solution inside the liquid storage tank 105 is pressurized. Then the controller 3 controls the electronic gas valve 90 4 is opened, a part of the compressed gas will enter the interior of the sleeve 202 through the electronic gas valve 1 904 and the gas pipe 2 207, and push the two push rods 204 to move in two opposite directions. During the movement, the two push rods 204 respectively insert the pins 401 into the inner cavity of the socket 82 through the clamping piece 206, and insert the electrode 30 into the sliding sleeve 104, and drive the sliding sleeve 104 to slide on the fixed sleeve 103. When the sliding sleeve 104 slides, it will push the conical block 107 to slide on the fixed block 106, so that a gap appears between the conical block 107 and the fixed block 106, and then the zero-point solution in the liquid storage tank 105 enters the interior of the slideway 102 through the gap between the conical block 107 and the fixed block 106 under the action of gas pressure and immerses the sliding sleeve 104. In addition, the zero-point solution enters the interior of the sliding sleeve 104 and immerses the detection end of the electrode 30, so that the detection end of the electrode 30 is fully in contact with the zero-point solution.

[0057] Since the detector 8 has a built-in battery and can provide stable power output, when the pin 401 is inserted into the socket 82 and the electrode 30 in the opposite direction is immersed in the zero-point solution, the detector 8 and the electrode 30 form a pathway and transmit appropriate power to the electrode 30. The electrode 30 is calibrated multiple times and the data is recorded for comparison to determine whether the electrode 30 is damaged during the bump or collision process. Under the premise that the battery inside the detector 8 can supply power stably, if the numerical difference after multiple tests of the electrode 30 is within the error range, it is determined that the electrode 30 is not damaged. If the numerical difference after multiple tests of the electrode 30 is outside the error range, it is determined that the electrode 30 is damaged. At the same time, the alarm 5 sounds an alarm to remind the operator that the electrode 30 is damaged due to bumps or collisions.

[0058] Although the operator will calibrate the electrode 30 before testing the wastewater, if the electrode 30 has been damaged due to bumps or collisions during the carrying process, then the operator's calibration of the damaged electrode 30 is equivalent to doing useless work. If the above-mentioned self-test operation is adopted, when the electrode 30 has been damaged due to bumps or collisions, the alarm 5 can alarm to remind the operator that the electrode 30 is damaged. When arriving at the detection point, the operator directly replaces the damaged electrode 30 with a new electrode 30, and then calibrates the new electrode 30 to detect heavy metals in the wastewater. Through this self-test method, the operator reduces the steps of calibrating the damaged electrode 30, which not only saves manpower, but also shortens the time of the entire detection process, and indirectly improves the detection efficiency.

[0059] In order to solve the problem that the existing industrial wastewater heavy metal rapid detection device cannot assist operators in troubleshooting, such as Figure 3 , Figure 5 and Fig.12 - Fig.17 As shown:

[0060] The first battery 50 includes a battery body 501 placed in the first mounting groove 12 , and a static contact 502 is provided on the side wall of the battery body 501 .

[0061] The second battery 60 includes a second battery body 601 placed in the first mounting groove 12 , and a second static contact 602 is disposed on the side wall of the second battery body 601 .

[0062] The second compression assembly 80 includes a compression plate 802 slidably mounted in the inner cavity of the compression chamber 130, a pair of fixing bars 803 are fixedly mounted on the side walls of the inner cavity of the compression chamber 130, the fixing bars 803 and the compression plate 802 are elastically connected via a fourth spring 804, an arc-shaped slide plate 801 is fixedly mounted on the top surface of the compression plate 802, an electronic valve 3 805 is provided at the connection between the airway 18 and the compression chamber 130, and an electronic valve 4 806 is provided at the connection between the airway 19 and the compression chamber 130.

[0063] The shifting assembly 70 includes a bracket 701 fixedly mounted on the side wall of the inner cavity of the first mounting groove 12, and a mounting cylinder 1 702 and a mounting cylinder 2 705 are fixedly mounted on the upper opposite sides of the bracket 701 respectively. A push rod 1 703 is slidably mounted inside the mounting cylinder 1 702, and the push rod 1 703 and the mounting cylinder 1 702 are elastically connected by a fifth spring 704. A push rod 2 706 is slidably mounted inside the mounting cylinder 2 705, and the push rod 2 706 and the mounting cylinder 2 705 are elastically connected by a sixth spring 707. A pressure relief valve 2 708 is connected on the top wall of the mounting cylinder 1 702, and a pressure relief valve 3 709 is connected on the top wall of the mounting cylinder 2 705. The moving contact 83 is slidably mounted on the bracket 701.

[0064] Specifically, the battery body 501 and the static contact 502 are electrically connected to the controller 3, and the controller 3 can monitor in real time whether the first battery 50 and the second battery 60 are in a stable power supply state. When it is determined through the collected data that the calibration error of the electrode 30 is large, there is another situation at this time: the electrode 30 is not damaged, but the battery inside the detector 8 cannot provide stable power supply after bumps or collisions; which leads to a large calibration error of the electrode 30. At this time, the controller 3 controls the electronic gas valve three 805 and the pressure relief valve two 708 to open, and the pressure relief valve three 709 to close. The purpose of opening the pressure relief valve two 708 is to enable the push rod one 703 to be pushed into the interior of the installation tube one 702, so that the push rod two 706 can push the moving contact 83 to move, and the compressed gas will enter the inner cavity of the installation tube two 705 through the airway two 18, pushing the push rod two 706 moves toward the outside of the mounting tube 705, and synchronously pushes the moving contact 83 to move until the moving contact 83 contacts the static contact 502. The controller 3 controls the electronic valve 3 805 to close, and positions the moving contact 83. Under the program control and circuit coordination settings built into the detector 8, when the battery body 501 forms a path with the detector 8 and the electrode 30, the built-in battery of the detector 8 does not supply power. At this time, the battery body 501 provides stable power to the detector 8 and the electrode 30, calibrates the electrode 30 multiple times, and records the data. If the difference in values ​​after multiple tests of the electrode 30 is within the error range, it is judged that the electrode 30 is not damaged, but is caused by the inability of the battery inside the detector 8 to provide stable power supply. If the value of the electrode 30 is still outside the error range after multiple tests, it can be preliminarily determined that there is a high probability that the electrode 30 is damaged.

[0065] When the controller 3 detects that the battery body 1 501 is damaged and the second battery 60 is used to test the electrode 30, the controller 3 controls the electronic gas valve 4 806 and the pressure relief valve 3 709 to open, and the pressure relief valve 2 708 to close. The purpose of opening the pressure relief valve 3 709 is to enable the push rod 2 706 to be pushed into the interior of the installation cylinder 2 705, so that the push rod 1 703 can push the moving contact 83 to move. The compressed gas will enter the installation cylinder 1 702 through the air channel 3 19 and push the push rod 1 703 to move. During the movement of the push rod 1 703, the moving contact 83 will be synchronously driven on the bracket 701. Move until the moving contact 83 contacts the static contact 2 602, the controller 3 controls the electronic valve 4 806 to close, and then positions the moving contact 83, and then the battery body 2 601 provides stable electric energy to detect the electrode 30, and when any one of the first battery 50 or the second battery 60 is damaged, it will not affect the judgment of the fault. In addition, when the battery in the detector 8 is damaged, the first battery 50 or the second battery 60 can also be used as a backup power supply, and the first battery 50 and the second battery 60 can be switched between each other, which is more flexible.

[0066] Through the above operations, the operator can quickly make a preliminary judgment on the fault location. Therefore, the operator can take corresponding measures to solve the fault and avoid using faulty equipment for detection. This not only improves the troubleshooting rate and shortens the duration of the detection process, but also improves the accuracy and availability of the detection results.
