Abstract

This utility model provides a lifting detection device, which includes a reaction vessel, a detection element, a lifting assembly, and a rinsing assembly. A reaction chamber is formed inside the reaction vessel, and the detection element is disposed within the reaction chamber, having a detection end for detecting liquid. The lifting assembly is fixed to the reaction vessel and has a movable end that extends into the reaction vessel and can be raised and lowered. The detection element is fixed to the movable end, which allows the detection element to move relative to the reaction vessel. The rinsing assembly is fixed to the reaction vessel and has a spray end that extends into the reaction vessel, facing the detection end when it is not in a detection state, for spraying liquid onto the detection end for cleaning. When detection is required, the detection element is lowered below the liquid level for detection. After detection, the detection element is detached from the liquid surface. This significantly reduces the contact time between the detection element and the liquid in the reaction vessel, extending the service life of the detection element. The rinsing assembly is used to wash away residual liquid at the end of the detection end, preventing residual liquid from corroding the detection element.

[0028] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0029] like Figure 1 As shown, an embodiment of this utility model provides a lifting detection device, which includes: a reaction vessel 1, a detection element 2, a lifting assembly 3, and a rinsing assembly 4. A reaction chamber is formed inside the reaction vessel 1. The detection element 2 is disposed inside the reaction chamber and has a detection end for detecting liquid. The lifting assembly 3 is fixed to the reaction vessel 1 and has a movable end that extends into the reaction vessel 1 and can be raised and lowered. The detection element 2 is fixed to the movable end, which allows the detection element 2 to move relative to the reaction vessel 1. It has at least a detection state where the detection end is immersed in liquid and a non-detection state where the liquid level is above the detection end. The rinsing assembly 4 is fixed to the reaction vessel 1 and has a spray end that extends into the reaction vessel 1. The spray end faces the detection end in the non-detection state and is used to spray liquid onto the detection end for cleaning.

[0030] In this invention, a lifting assembly 3 and a rinsing assembly 4 are provided. The lifting assembly 3 can move the detection element 2 up and down so that the detection element 2 can be immersed in the liquid or above the liquid level. When testing is required, the detection element 2 is lowered below the liquid level for testing. After the test is completed, the detection element 2 is separated from the liquid surface. This significantly reduces the contact time between the detection element 2 and the liquid in the reactor, extending the service life of the detection element 2. The rinsing assembly 4 is used to clean the detection end when it is not in the testing state, washing away the residual liquid at the end of the detection end to prevent the residual liquid from corroding the detection element 2, further protecting the detection element 2 and extending its service life.

[0031] Specifically, the reaction vessel 1 includes a vessel body 11 and a detection tube 12. One end of the detection tube 12 is connected to the vessel body 11, and the lifting assembly 3 is fixed to the other end of the detection tube 12. The lifting end of the lifting assembly 3 extends into the detection tube 12, and the detection element 2 is disposed inside the detection tube 12 and fixed to the lifting end of the lifting assembly 3. The purpose of this design is to utilize the principle of communicating vessels to guide a portion of the liquid in the vessel body into the detection tube 12, thereby avoiding other components inside the vessel body 11 and facilitating detection by the detection element 2.

[0032] Furthermore, the vessel body 11 and the detection tube body 12 are connected by a connecting pipe 13. A filter element 14 is installed inside the connecting pipe 13. The filter element 14 filters the liquid flowing from the vessel body 11 to the detection tube body 12, preventing reaction residues from entering the detection tube body 12 and settling at the detection end of the detection element 2. This further protects the detection element 2 and extends its service life.

[0033] Furthermore, the detection element 2 includes a detection body 21 and a detection head 22. The detection body 21 is fixed outside the detection tube 12, and the detection head 22 is disposed inside the detection tube 12 and fixed on the lifting end of the lifting assembly 3. The detection head 22 is electrically connected to the detection body 21 and serves as the detection end of the detection element 2.

[0034] It should be noted that the detection body 21 and the detection head 22 in the detection component 2 are conventional components in the prior art, which are well known and skillfully applied by those skilled in the art, so their specific structures will not be described in detail here.

[0035] The lifting assembly 3 functions to move the detection head 22 up and down, switching it between a detection state and a non-detection state. In other feasible embodiments, the lifting assembly 3 includes a lifting cylinder and a connecting rod. The lifting cylinder is fixed to the detection tube 12. One end of the connecting rod is fixed to the movable end of the lifting cylinder, and the other end extends into the detection tube 12. The detection head 22 is fixed to the end of the connecting rod located inside the detection tube 12. The movable end of the lifting cylinder extends and retracts, moving the detection head 22 up and down within the detection tube 12. When the detection head 22 is lowered below the liquid level, it is immersed in the liquid and enters the detection state, detecting the liquid and sending a detection signal to the detection body 21. The detection body 21 then generates a detection result based on the detection signal. When the detection head 22 is raised above the liquid level, it loses contact with the liquid and enters the non-detection state.

[0036] Furthermore, the lifting assembly 3 includes a lifting motor 31, a screw 32, and a lifting plate 33. The lifting motor 31 is fixed to the top of the detection tube 12. One end of the screw 32 is fixed to the movable end of the lifting motor 31, and the other end extends into the detection tube 12 and is below the liquid level. The lifting plate 33 is threadedly connected to the screw 32, and the detection head 22 is fixed on the lifting plate 33. The lifting motor 31 drives the screw 32 to rotate, causing the lifting plate 33 to rise and fall along the screw 32. When the lifting plate 33 falls below the liquid level, the detection head 22 is immersed in the liquid and enters the detection state to detect the liquid. The detection signal is sent to the detection body 21, which generates a detection result based on the detection signal. When the lifting plate 33 rises above the liquid level along the screw 32, the detection head 22 loses contact with the liquid and enters the non-detection state. The purpose of this design is to ensure that the detection head 22 is in a state of non-contact with the liquid most of the time, and only comes into contact with the liquid during detection; this greatly reduces the contact time between the detection head 22 and corrosive liquid, thereby extending its service life.

[0037] Specifically, the shower assembly 4 includes a water tank 41, a liquid supply pump, and a spray head 42. The water tank 41 is fixed to the detection tube 12. The inlet of the liquid supply pump is connected to the water tank 41 via a pipe, and the outlet of the liquid supply pump is connected to the spray head 42 via a pipe. The spray head 42 is disposed inside the detection tube 12 and faces the detection element 2 when it is in the non-detection state. In use, when the detection element 2 is in the non-detection state, the liquid supply pump draws clean water from the water tank 41 and sends it to the spray head 42. The spray head 42 sprays clean water onto the detection head 22 to clean it.

[0038] Furthermore, a one-way solenoid valve 15 is provided at the connection between the connecting pipe 13 and the vessel body 11, which only allows liquid to flow from the vessel body 11 to the connecting pipe 13. The filter element 14 is provided at the connection between the connecting pipe 13 and the detection pipe 12. A slag discharge valve for discharging filter residue is provided in the middle of the connecting pipe 13. An openable and closable drain port is provided at the bottom of the detection pipe 12. The purpose of this design is that after the spray head 42 sprays and cleans the test piece 2, the cleaning liquid will fall into the test tube 12, causing the liquid in the test tube 12 to become diluted. This part of the liquid is no longer suitable for flowing back to the reactor 11 for production. Therefore, the one-way solenoid valve 15 can prevent the liquid from flowing back to the reactor 11. The filter element 14 will filter the solids in the liquid into the connecting pipe 13. The filter residue will gradually accumulate in the connecting pipe 13. The slag discharge valve is used to discharge the filter residue to prevent the filter residue from accumulating in the connecting pipe 13 and clogging the pipe. After the test is completed, the drain port at the bottom of the test tube 12 will open to discharge the liquid.

The detection element is disposed within the reaction chamber and has a detection end for detecting liquid. The lifting assembly is fixed to the reaction vessel and has a movable end extending into the reaction vessel and capable of lifting and lowering.

The assembly has at least two states: a detection state where the detection end is immersed in the liquid and a non-detection state where the liquid level is above the detection end. The shower assembly is fixed to the reaction vessel and has a spray end extending into the reaction vessel, with the spray end facing the non-detection state. The detection end is used to spray liquid onto the detection end for cleaning; the lifting assembly can drive the detection element to rise and fall so that the detection element can be immersed in the liquid or above the liquid level.
