Description

Technical Field

[0001] This utility model relates to the field of pH value determination technology for dyeing auxiliaries, and in particular to a pH value determination device for the production of dyeing auxiliaries. Background Technology

[0002] Dyeing auxiliaries are auxiliary agents used in the dye industry to promote the interaction between dyes and fibers and improve the dyeing effect. During the production of dyeing auxiliaries, in order to ensure that their pH value meets the requirements, a pH value measuring device is used to measure the pH value of the dyeing auxiliaries during production to ensure the production quality of dyeing auxiliaries.

[0003] A pH measuring device for dyeing auxiliary production, as disclosed in utility model patent CN220040374U, includes a reaction vessel. A feed pipe is located on one side of the top of the reaction vessel. A buoyancy mechanism is located on the outer side of the bottom of the pH meter. A locking mechanism is located at the connection between the positioning cover and the vertical rod. A guide mechanism is located on one side of the vertical rod. In this pH measuring device, one hand holds the anti-detachment plate, and the other hand pulls the fixing plate to the left, causing the fixing plate to move the locking rod to the left, separating the end of the locking rod from the locking hole. Then, the hand moves downwards, and the pH meter moves downwards under gravity. When the buoyancy block contacts the water surface, the buoyancy generated by the buoyancy block ensures that only the lower end of the pH meter is inserted into the mixture, preventing water from entering the pH meter and protecting the internal electronic components, thus extending the service life of the pH meter. However, in the application of this technical solution, the pH meter is manually raised and lowered to contact the dyeing auxiliaries. The manual raising and lowering height is not accurately and is unstable. There is a technical problem that it is not possible to accurately and stably measure the pH value of the dyeing auxiliaries in production by raising and lowering the pH meter in conjunction with the level gauge. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a pH value measuring device for the production of dyeing auxiliaries. It can solve the technical problem that the manual raising and lowering of the pH value measuring instrument to contact the dyeing auxiliaries is not accurate and unstable, and there is no way to stably and accurately measure the pH value of the dyeing auxiliaries in production by raising and lowering the pH value measuring instrument in conjunction with the liquid level gauge.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a pH value measuring device for the production of dyeing auxiliaries, comprising a reaction vessel, a level gauge at the front end of the reaction vessel, a stirring mechanism inside the reaction vessel, a positioning sleeve passing through one side of the top of the reaction vessel, a pH value measuring instrument passing through the inside of the positioning sleeve, a housing on one side of the positioning sleeve at the top of the reaction vessel, a lead screw at the middle position between the two ends inside the housing, a servo motor at the top of the housing, a lifting sleeve near the top of the lead screw, a limiting groove at the middle position of one side of the housing, a connecting vertical plate on one side of the lifting sleeve, and a sealing assembly between the top of the positioning sleeve and the outside of the pH value measuring instrument.

[0006] As a preferred embodiment of this utility model, the top end of the lead screw passes through the top end of the housing and is connected to the output end of the servo motor, and one side of the connecting vertical plate passes through the limiting groove and is connected to one side of the pH value measuring instrument.

[0007] As a preferred embodiment of this utility model, the thickness of the connecting vertical plate is less than the width of the defined groove, and the connecting vertical plate can move up and down within the defined groove.

[0008] As a preferred embodiment of the present invention, the stirring mechanism includes a drive motor, which is located at the middle position of the top of the reaction vessel. A stirring rack is provided inside the reaction vessel, and a sealing bushing is provided at the middle position of the top of the reaction vessel. The top of the stirring rack passes through the interior of the sealing bushing and is connected to the output end of the drive motor.

[0009] As a preferred technical solution of this utility model, the sealing assembly includes a sealing cover, which is disposed at both ends between the top of the positioning sleeve and the outside of the pH meter. Magnetic blocks are provided at both ends of the sealing cover. A first sealing gasket is provided at the top of the inner side of the sealing cover, and a second sealing gasket is provided at the bottom of the inner side of the sealing cover.

[0010] As a preferred embodiment of this utility model, the sealing cover, the first sealing gasket, and the second sealing gasket are semi-circular, and the inner bottom diameter of the sealing cover is larger than the inner top diameter.

[0011] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0012] 1. By installing a lifting and positioning component on one side of the top of the reactor, the servo motor is started to drive the lead screw to rotate and drive the lifting sleeve to descend. The pH meter is then lowered into the reactor via the connecting vertical plate to measure the pH value of the dyeing auxiliaries in production. After the measurement is completed, the lead screw is driven in the opposite direction to lift the pH meter. At the same time, the connecting vertical plate is limited and stabilized by the limiting groove to ensure the stability of the pH meter during lifting. This achieves a stable, efficient, and accurate lifting and moving of the pH meter to measure the pH value of the dyeing auxiliaries in production, making it more operable.

[0013] 2. By installing a sealing component between the top of the positioning sleeve and the outside of the pH meter, when not performing pH measurement, the semi-circular sealing cap is engaged between the top of the positioning sleeve and the outside of the pH meter, and the two are magnetically connected by a magnetic block. At the same time, the first and second sealing gaskets seal the contact surfaces between the sealing cap, the positioning sleeve, and the pH meter, thus sealing the gap between the pH meter and the positioning sleeve. This prevents dust and foreign matter from entering the reaction vessel through the gap between the positioning sleeve and the pH meter and contaminating the auxiliary agents during the production and preparation of dyeing auxiliaries. This method is highly feasible. Attached Figure Description

[0019] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0020] Example

[0021] Please refer to Figure 1-4 As shown, this utility model provides a pH value measuring device for the production of dyeing auxiliaries, including a reaction vessel 1. A level gauge 2 is provided at the front end of the reaction vessel 1. A drive motor 7 is provided at the middle position of the top of the reaction vessel 1. A stirring rack 8 is provided inside the reaction vessel 1. A sealing bushing 11 is provided at the middle position of the top of the reaction vessel 1. The top of the stirring rack 8 passes through the interior of the sealing bushing 11 and is connected to the output end of the drive motor 7. The drive motor 7 drives the stirring rack 8 to rotate and stir the dyeing auxiliaries produced in the reaction vessel 1. A positioning sleeve 3 is provided on one side of the top of the reaction vessel 1. A pH value measuring instrument 5 passes through the interior of the positioning sleeve 3. The pH value of the dyeing auxiliaries is measured by inserting the pH value measuring instrument 5 into the reaction vessel 1. At the same time, the positioning sleeve 3 stabilizes the pH value measuring instrument 5.

[0022] As a further implementation of this embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, a housing 6 is provided on one side of the top positioning sleeve 3 of the reactor 1. A lead screw 10 is provided at the middle position between the two ends inside the housing 6. A servo motor 9 is provided at the top of the housing 6. The top of the lead screw 10 passes through the top of the housing 6 and is connected to the output end of the servo motor 9. A lifting sleeve 12 is provided near the top of the lead screw 10. A limiting groove 13 is provided at the middle position of one side of the housing 6. A connecting vertical plate 14 is provided on one side of the lifting sleeve 12. One side of the connecting vertical plate 14 passes through the limiting groove 13 and is connected to one side of the pH meter 5. The machine 9 drives the lead screw 10 to rotate and lowers the lifting sleeve 12. This allows the pH meter 5 to descend into the reaction vessel 1 via the connecting vertical plate 14 to measure the pH value of the dyeing auxiliaries in production. The thickness of the connecting vertical plate 14 is less than the inner width of the limiting groove 13, allowing the connecting vertical plate 14 to move up and down within the limiting groove 13. The limiting groove 13 stabilizes the connecting vertical plate 14, ensuring the stability of the pH meter 5 during its movement. This achieves a stable, efficient, and precise lifting and moving of the pH meter 5 to measure the pH value of the dyeing auxiliaries in production.

[0023] When in use, the servo motor 9 is started to drive the lead screw 10 to rotate and drive the lifting wire sleeve 12 to descend. The pH value meter 5 can be driven to the reaction vessel 1 through the connecting vertical plate 14 to measure the pH value of the dyeing auxiliary agent in production. After the measurement is completed, the lead screw 10 is driven to rotate in the opposite direction to lift the pH value meter 5. At the same time, the connecting vertical plate 14 is limited and stabilized by the limiting groove 13.

[0024] As a further implementation of this embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, a sealing assembly is provided between the top of the positioning sleeve 3 and the outside of the pH meter 5. The sealing assembly includes a sealing cap 4, which is located at both ends between the top of the positioning sleeve 3 and the outside of the pH meter 5. The diameter of the bottom inner side of the sealing cap 4 is larger than the diameter of the top inner side. Magnetic blocks 16 are provided at both ends of the sealing cap 4. After the pH measurement is completed, the semi-circular sealing cap 4 is engaged and locked between the top of the positioning sleeve 3 and the outside of the pH meter 5, and the two are magnetically connected by the magnetic blocks 16. A semi-circular first sealing gasket 15 is provided on the top of the inner side, and a semi-circular second sealing gasket 17 is provided on the bottom of the inner side of the sealing cover 4. The first sealing gasket 15 and the second sealing gasket 17 are used to seal the contact surfaces of the sealing cover 4 with the positioning sleeve 3 and the pH meter 5, thereby achieving the purpose of sealing the gap between the pH meter 5 and the positioning sleeve 3. This prevents dust and foreign objects from entering the reaction vessel 1 through the gap between the positioning sleeve 3 and the pH meter 5 and contaminating the auxiliary agent during the production and preparation of the dyeing auxiliary agent. This method is highly feasible.

[0025] When not performing pH measurement, the semi-circular sealing cap 4 is engaged between the top of the positioning sleeve 3 and the outside of the pH meter 5, and the two are magnetically connected by the magnetic block 16. At the same time, the first sealing gasket 15 and the second sealing gasket 17 seal the contact surfaces between the sealing cap 4, the positioning sleeve 3 and the pH meter 5, thus sealing the gap between the pH meter 5 and the positioning sleeve 3.

[0026] Specific working principle:

[0027] When using the pH measuring device, the dyeing auxiliary agent is prepared by stirring in the reaction vessel 1. When the pH value needs to be measured, the servo motor 9 is started to drive the lead screw 10 to rotate and drive the lifting sleeve 12 to descend. The pH measuring instrument 5 is then lowered into the reaction vessel 1 via the connecting vertical plate 14 to measure the pH value of the dyeing auxiliary agent in production. After the measurement is completed, the lead screw 10 is driven in the reverse direction to rotate and lift the pH measuring instrument 5. At the same time, the connecting vertical plate 14 is limited and stabilized by the limiting groove 13. After the measurement is completed, the semi-circular sealing cover 4 is engaged between the top of the positioning sleeve 3 and the outside of the pH measuring instrument 5, and the two are magnetically connected by the magnetic block 16. At the same time, the first sealing gasket 15 and the second sealing gasket 17 seal the contact surfaces of the sealing cover 4, the positioning sleeve 3 and the pH measuring instrument 5, thus sealing the gap between the pH measuring instrument 5 and the positioning sleeve 3, thereby enabling accurate, efficient and safe pH value measurement of the dyeing auxiliary agent.
