Description

Technical Field

[0001] The present invention relates to the technical field of liquid monitoring, and in particular to an on-line color detection device for dangerous chemical liquid media. Background Technique

[0002] An on-line color detection device for dangerous chemical liquid media is a device used to monitor the color of liquids in real time, especially suitable for occasions where quality control and safety monitoring of liquid media are required during industrial production processes. Such devices usually adopt optical sensing technology, which can accurately measure the color changes of liquids and perform analysis and determination according to preset standards or ranges.

[0003] However, during the production process, the detection of chemicals requires taking out the produced chemicals from the container and then placing them on the corresponding detection device for testing. During this process, workers need to wear protective clothing and conduct multiple sampling tests, which is time-consuming and laborious and also has multiple potential hazards. Workers may accidentally come into contact during the process of transferring chemicals, resulting in injuries.

[0004] To solve the above problems, we have proposed an on-line color detection device for dangerous chemical liquid media. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems in the background technique, and an on-line color detection device for dangerous chemical liquid media is proposed.

[0006] To achieve the above purpose, the present invention adopts the following technical solution: An on-line color detection device for dangerous chemical liquid media, including a tank body, a vertically arranged base is fixedly sleeved at the bottom end of the tank body, a discharge pipe is fixedly connected to the bottom end of the tank body, a horizontally arranged conduit one and a conduit one are respectively fixedly connected to the discharge pipe and the outer side wall of the tank body, the ends of the conduit one far away from the discharge pipe and the ends of the conduit two far away from the tank body are both fixedly connected with vertically arranged U-shaped pipes, the middle parts of the two U-shaped pipes and the conduit one and the conduit two are respectively communicated with each other and the two U-shaped pipes are arranged opposite to each other, two transparent pipes are commonly connected between the two U-shaped pipes, and the two transparent pipes are respectively connected to the upper and lower corresponding ports of the two U-shaped pipes;

[0007] Two symmetrically arranged first support plates are fixedly connected to the base. The two first support plates are horizontally arranged and are respectively located on both sides of the two transparent tubes. A second support plate located between the two transparent tubes is horizontally arranged between the two first support plates and is fixedly connected to the base. Support seats are vertically arranged on the first support plates. A first fixing rod is horizontally connected between the two support seats. Two first sleeves are horizontally connected to the first fixing rod and are respectively sleeved at the joints of the two transparent tubes and the upper U-shaped tube. Collars are fixedly sleeved at the joints of the two ports of the lower U-shaped tube and the two transparent tubes. Horizontal second fixing rods are fixedly connected between the two collars and the two support seats.

[0008] Battery packs are fixedly arranged on the opposite sides of the two support seats. On the opposite sides of the two support seats, irradiation lamps located on the same horizontal axis are respectively fixedly connected. A vertically arranged sliding seat is slidably sleeved on the first fixing rod and the second fixing rod. A fastening ring is arranged in the middle of the sliding seat. An optical instrument is sleeved inside the fastening ring. A knob for fastening the optical instrument is arranged on the outer side wall of the fastening ring. A photometric plate is slidably sleeved on the first fixing rod and is located between the two transparent tubes. A receiver is arranged on the second support plate, and the receiving port of the receiver is on the same axis as the two irradiation lamps. A chromatographic plate is vertically connected to the front end of the receiver.

[0009] In the above-mentioned on-line color detection device for hazardous chemical liquid media, a hydraulic pump is fixedly connected to the second conduit and is fixedly connected to the outer side wall of the tank body.

[0010] In the above-mentioned on-line color detection device for hazardous chemical liquid media, the first support plate and its connecting parts are arranged in the same way as the second support plate and its connecting parts and are symmetrically arranged with respect to the tank body.

[0011] In the above-mentioned on-line color detection device for hazardous chemical liquid media, a first bolt for fixing the sliding seat is arranged on the sliding seat and is at the same height as the first fixing rod.

[0012] In the above-mentioned on-line color detection device for hazardous chemical liquid media, inclined surfaces for facilitating the observation of the projected light are arranged on both sides of the photometric plate, and granular dots are arranged on the front and back sides of the photometric plate.

[0013] In the above-mentioned on-line color detection device for hazardous chemical liquid media, three jacks corresponding to the first support plate and the second support plate are opened at the bottom end of the base. The ports of the jacks are located on the outer side wall of the base and the lengths of the three jacks are equal.

[0014] In the above-mentioned on-line color detection device for hazardous chemical liquid medium, the fastening ring located in the middle of the sliding seat consists of a fixed sleeve, a soft clamping sleeve and two springs. The soft clamping sleeve is sleeved in the fixed sleeve and its upper and lower ends are connected to the fixed sleeve. The springs are located between the fixed sleeve and the soft clamping sleeve and are respectively located on the left and right sides of the soft clamping sleeve.

[0015] Compared with the existing technology, the advantages of the on-line color detection device for hazardous chemical liquid medium are as follows:

[0016] 1. The device connects the bottom end and the middle part of the tank body 1 through the first conduit, the second conduit, the U-shaped tube and the transparent tube. When the chemicals are stirred in the device, a small part of the material may gather at the connection between the bottom end of the tank body and the discharge pipe, resulting in insufficient mixing of the materials. However, through the connection of each pipeline, under the action of the hydraulic pump, the materials gathered at the bottom end of the tank body will be brought to the middle part of the tank body and fully mixed with the remaining liquid, improving the reaction rate of the chemicals. Moreover, the two U-shaped tubes and the two transparent tubes form a circular channel, causing the liquid to be divided when passing through the transparent tube to reduce its flow rate, making the liquid in the transparent tube in a relatively static state, which is convenient for the subsequent light emitted by the irradiation lamp to form an image in the transparent tube.

[0017] 2. For the liquid color detection, two relatively arranged irradiation lamps are used. The two irradiation lamps will simultaneously irradiate different transparent tubes and finally form an image on the receiver. The changes in the two transparent tubes occur simultaneously, contrasting with each other, reducing the occurrence of special situations, and the data obtained from the imaging is more accurate. Moreover, the receiver is connected to the stirring mechanism in the tank body and the external display in real time. By detecting the liquid in the transparent tube, the start and stop of the stirring can be controlled, and early warning can be given for the reaction of the chemicals and it can be detected whether it reaches the predetermined standard.

[0018] In the present invention, through the connection of each conduit, the sediment located at the bottom of the tank is pumped back to the middle part of the tank body to fully mix the materials, and the flow rate of the liquid in the transparent tube is reduced by using the shunt U-shaped tube, making the liquid in the transparent tube in a relatively static state, which is convenient for the subsequent detection of the liquid color.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0025] Referring to Figures 1-4 , an on-line color detection device for liquid media of hazardous chemicals includes a tank body 1. A vertically arranged base 2 is fixedly sleeved at the bottom end of the tank body 1. A discharge pipe 3 is fixedly connected to the bottom end of the tank body 1.

A hydraulic pump 23 is fixedly connected to the second conduit 5 and is fixedly connected to the outer side wall of the tank body 1. The end of the first conduit 4 far from the discharge pipe 3 and the end of the second conduit 5 far from the tank body 1 are both fixedly connected to a vertically arranged U-shaped pipe 6. The middle parts of the two U-shaped pipes 6 and the first conduit 4 and the second conduit 5 are respectively interconnected, and the two U-shaped pipes 6 are arranged opposite to each other. Two transparent pipes 7 are commonly connected between the two U-shaped pipes 6. The two transparent pipes 7 are respectively connected to the upper and lower corresponding ports of the two U-shaped pipes 6, so that the connection between the bottom end of the tank body 1 and the discharge pipe 3 is communicated with the middle part of the tank body 1, so that the logistics deposited at the bottom end of the tank body 1 during stirring flows back to the middle part of the tank body 1, and the materials are fully fused;

[0026] Two symmetrically arranged first support plates 8 are connected to the base 2. The two first support plates 8 are horizontally arranged and are respectively located on both sides of the two transparent tubes 7. A second support plate 9 located between the two transparent tubes 7 is horizontally arranged between the two first support plates 8 and is connected to the base 2. Three jacks corresponding to the first support plates 8 and the second support plate 9 are provided at the bottom end of the base 2. The ports of the jacks are located on the outer side wall of the base 2 and the lengths of the three jacks are equal. Support seats 10 are vertically arranged on the first support plates 8. A first fixing rod 11 is horizontally connected between the two support seats 10. Two first sleeves 12 are horizontally connected to the first fixing rod 11 and are respectively sleeved on the connections of the two transparent tubes 7 and the U-shaped tube 6 located on the upper side. Sleeve rings 14 are fixedly sleeved on the connections of the two ports of the U-shaped tube 6 located on the lower side and the two transparent tubes 7 respectively. A second fixing rod 13 horizontally arranged is fixedly connected between the two sleeve rings 14 and the two support seats 10. The first support plate 8 and its connecting parts are arranged in the same way as the second support plate 9 and its connecting parts and are symmetrically arranged with respect to the tank body 1;

[0027] Battery packs 18 are fixedly arranged on the opposite sides of the two support seats 10. Irradiation lamps 19 located on the same horizontal axis are respectively fixedly connected to the opposite sides of the two support seats 10. A vertically arranged sliding seat 15 is slidably sleeved on the first fixing rod 11 and the second fixing rod 13 together. A first bolt for fixing the sliding seat 15(1) is provided on the sliding seat 15 and is at the same height as the first fixing rod 11. A fastening ring is arranged in the middle of the sliding seat 15. The fastening ring consists of a fixed sleeve, a soft clamping sleeve and two springs. The soft clamping sleeve is sleeved in the fixed sleeve and its upper and lower ends are connected to the fixed sleeve. The springs are located between the fixed sleeve and the soft clamping sleeve and are respectively located on the left and right sides of the soft clamping sleeve. An optical instrument 16 is sleeved inside the fastening ring. The soft clamping sleeve can clamp the optical instrument 16 and also prevent damage to the optical instrument 16. A knob 17 for fastening the optical instrument 16 is arranged on the outer side wall of the fastening ring. A light measuring plate 20 is slidably sleeved on the first fixing rod 11 and is located between the two transparent tubes 7. Inclined surfaces for facilitating the observation of the projected light are arranged on both sides of the light measuring plate 20. Particle dots are arranged on the front and back sides of the light measuring plate 20 to increase the friction coefficient of the light measuring plate 20 and facilitate the rotation of the light measuring plate 20 on the first fixing rod 11. A receiver 21 is arranged on the second support plate 9 and the receiving port of the receiver 21 is on the same axis as the two irradiation lamps 19. A chromatographic plate 22 is vertically connected to the front end of the receiver 21. During operation, when the light of the irradiation lamp 19 passes through the transparent tube 7 and irradiates on the receiver 21, the light measuring plate 20 can be rotated to make it located on the left or right side of the receiver 21, and the light passing through the transparent tube 7 is irradiated on the light measuring plate 20. The chromatographic plate 22 is compared, and the color change is visually observed manually, and the data information of the receiver 21 is compared.

[0028] At the very beginning, the selected optical instrument 16 is installed on the carriage 15 and clamped. The irradiation lamp 19 is turned on. Then, the two carriages 15 on the first fixed rod 11 and the second fixed rod 13 are adjusted. The two optical instruments 16 are moved left and right to converge the light onto the two transparent tubes 7 respectively. Then, the color signal is received by the receiver 21. At this time, the hydraulic valve is opened, and the liquid in the tank body 1 will flow through the first conduit 4, pass through the U-shaped tube 6 and be shunted and decelerated into the transparent tube 7. When there are particles left due to insufficient reaction in the tube, the receiver 21 will cause the inside of the tank body 1 to continue stirring. Other conditions such as concentration will transmit the signal to the external receiver to remind the worker to fill the material or perform other interventions. When the chemical meets the requirements, the stirring inside the tank body 1 stops, the hydraulic pump 23 stops operating, and the liquid in the pipeline will flow back through the first conduit 4 into the discharge pipe 3 in the reverse direction.

[0029] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
