It includes an outer tank, the inner cavity of which is cast with a guide ring plate, water flow holes on the surface of the outer tank, a collection assembly on the surface of the outer tank, and an inner frame extending through the top of the outer tank. In this invention, when the bottom of the outer tank is corroded and broken, acid leakage occurs. The leaked acid flows into the bottom shell. The acidity or alkalinity of the liquid in the bottom shell is detected by an acid-alkalinity detector. When the acid mixes with the water in the bottom shell, the acidity or alkalinity of the water decreases, making it acidic. Items to be acid-treated are placed in the inner frame, and then the inner frame is inserted into the outer tank. The items are then acid-treated by the acid inside the outer tank. After acid treatment, the inner frame is pulled out of the outer tank. During the pulling process, a water pump extracts lime water from the water tank and sprays it out through a spray nozzle.

Description

Technical Field

[0001] This utility model relates to the field of experimental equipment technology, specifically to a laboratory acid tank with a leakage alarm function. Background Technology

[0002] An acid tank is a corrosion-resistant laboratory container, mainly used for soaking laboratory glassware or storing diluted sulfuric acid or a mixture of potassium dichromate and sulfuric acid, nitric acid, hydrochloric acid, and other liquids. The material has the characteristics of being resistant to strong acids and alkalis, non-scaling, and high strength.

[0003] A search revealed that the publication number is CN212595762U, and the title is "A Laboratory Acid Tank with Rinsing Function, Including an Outer Tank." Research and analysis showed that although it has the advantages of automatically rinsing the inner wall of the outer tank, thereby improving experimental safety and reducing labor costs, it also has the following disadvantages to some extent.

[0004] For example, during use, this device can only rinse the inner wall of the outer cylinder. During long-term use of the acid cylinder, the bottom will be corroded. Corrosion inside the acid cylinder will cause the acid inside to leak out. It cannot alarm after the acid leaks out, which is not conducive to the personal safety of the staff. In order to solve the above technical problems, we have designed a laboratory acid cylinder with a leakage alarm function. Utility Model Content

[0005] The purpose of this invention is to provide a laboratory acid cylinder with a leakage alarm function. It has the advantage of leakage alarm and solves the problem that the device can only rinse the inner wall of the outer cylinder during use. During long-term use, the bottom of the acid cylinder will be corroded, and the acid inside the cylinder will leak out. The device cannot alarm after the acid leaks out, which is detrimental to the personal safety of the staff.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a laboratory acid cylinder with a leakage alarm function, comprising an outer cylinder, a guide ring plate cast in the inner cavity of the outer cylinder, water flow holes opened on the surface of the outer cylinder, a collection assembly provided on the surface of the outer cylinder, an inner frame extending through the top of the outer cylinder, a water tank bolted to the right side of the outer cylinder, a water pump bolted to the top of the water tank, a water spray shell bolted to the inner cavity of the outer cylinder, a bottom shell fixedly fitted to the bottom of the outer cylinder, a fixing block welded to the front side of the bottom shell, an acid-base detector bolted to the front side of the fixing block, and a speaker bolted to the front side of the acid-base detector.

[0007] Preferably, the collection assembly includes a collection box, the left side of the outer cylinder is connected to the collection box by bolts, and the surface of the outer cylinder is cast with a flow guide shell.

[0008] Preferably, the bottom of the flow guide shell is connected to the collection box via a pipe, and a first drain valve is connected to the left side of the collection box.

[0009] Preferably, a level gauge is installed on the front side of the outer cylinder, and the surface of the inner frame is slidably connected to the guide ring plate.

[0010] Preferably, a cover plate is rotatably connected to the rear side of the outer cylinder, a sealing ring is provided on the surface of the cover plate, and a handle is cast on the surface of the inner frame.

[0011] Preferably, the top of the water tank is connected to a second water inlet pipe, and the top of the second water inlet pipe is threaded with a first pipe cap. The top of the bottom shell is connected to a first water inlet pipe, and the top of the first water inlet pipe is threaded with a second pipe cap.

[0012] Preferably, the bottom of the inner cavity of the bottom shell is provided with zeolite, the right side of the bottom shell is connected to a second drain valve, and a microcontroller is installed inside the pH meter.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. In this invention, when the bottom of the outer cylinder is corroded and broken, acid leakage will occur. The leaked acid flows into the bottom shell. The acidity and alkalinity of the liquid in the bottom shell are detected by an acidity and alkalinity detector. When the acid mixes with the water in the bottom shell, the acidity and alkalinity of the water decreases, making it acidic. After the water is detected to be acidic, it indicates that there is a leak at the bottom of the outer cylinder. The microcontroller inside the acidity and alkalinity detector can be used to activate the speaker to sound an alarm. 2. This utility model places the items to be pickled in an inner frame, then inserts the inner frame into an outer cylinder. The items are pickled by the acid solution inside the outer cylinder. After pickling, the inner frame is pulled out of the outer cylinder. During the pulling process, a water pump extracts lime water from the water tank and sprays it out through a spray nozzle. The lime water sprayed out by the spray nozzle washes the surface of the inner frame, removing any residual acid solution. The water generated during rinsing is blocked by a guide ring plate and flows along the guide ring plate and then through the water outlet into the guide shell. Under the guidance of the guide shell, the water flows into the collection box for collection. Attached Figure Description

[0017] Please see Figure 1 and Figure 4 The collection component 21 includes a collection box 5. The left side of the outer cylinder 1 is connected to the collection box 5 by bolts. The surface of the outer cylinder 1 is cast with a guide shell 4. By setting the guide shell 4, it is easy to guide the water and to easily guide the lime water after rinsing into the collection box 5 for collection.

[0018] Please see Figure 1 and Figure 4 The bottom of the guide shell 4 is connected to the collection box 5 through a pipe. The left side of the collection box 5 is connected to the first drain valve 6. By setting the first drain valve 6, the wastewater in the collection box 5 can be discharged easily, which can effectively prevent the wastewater from damaging the collection box 5.

[0019] Please see Figure 1 and Figure 5 A level gauge 11 is installed on the front side of the outer cylinder 1. By setting the level gauge 11, it is easy to observe the amount of acid in the outer cylinder 1 and to add acid quantitatively to the outer cylinder 1. The surface of the inner frame 7 is slidably connected to the guide ring plate 2.

[0020] Please see Figure 1 and Figure 5A cover plate 20 is rotatably connected to the rear side of the outer cylinder 1. By setting the cover plate 20 and the sealing ring, the top of the outer cylinder 1 and the inner frame 7 can be sealed, which can effectively prevent acid from splashing out of the outer cylinder 1 and the inner frame 7. The surface of the cover plate 20 is provided with a sealing ring, and the surface of the inner frame 7 is cast with a handle. By setting the handle, it is easy for the staff to grip the inner frame 7 and to pull the inner frame 7 out of the outer cylinder 1.

[0021] Please see Figure 1 The top of the water tank 8 is connected to a second water inlet pipe 19. By setting the second water inlet pipe 19, it is easy to add lime water into the water tank 8 and to continuously rinse the surface of the inner frame 7. The top of the second water inlet pipe 19 is threaded with a first pipe cap. The top of the bottom shell 12 is connected to a first water inlet pipe 17. By setting the first water inlet pipe 17, it is easy to add water into the bottom shell 12 and to effectively prevent the water level in the first water inlet pipe 17 from being too low. The top of the first water inlet pipe 17 is threaded with a second pipe cap. By setting the first pipe cap and the second pipe cap, it is easy to seal the second water inlet pipe 19 and the first water inlet pipe 17 respectively, and to effectively prevent the liquid in the water tank 8 and the bottom shell 12 from spilling out.

[0022] Please see Figure 1 and Figure 2 The bottom of the inner cavity of the bottom shell 12 is provided with zeolite 18. By providing zeolite 18, it can play a role in stopping boiling and can effectively prevent the acid from reacting with water and causing violent boiling. The right side of the bottom shell 12 is connected to a second drain valve 16. By providing the second drain valve 16, it is easy to drain the water in the bottom shell 12 for replacement. The acidity and alkalinity detector 14 is equipped with a microcontroller.

[0023] The model number of water pump 9 is CDL.

[0024] The pH meter 14 is model FE28.

[0025] During use, if the bottom of the outer cylinder 1 is corroded and broken, acid leakage will occur. The leaked acid flows into the bottom shell 12. The acidity or alkalinity of the liquid in the bottom shell 12 is detected by the acidity or alkalinity detector 14. When the acid mixes with the water in the bottom shell 12, the acidity or alkalinity of the water decreases, making it acidic. The detection of acidic water indicates a leak at the bottom of the outer cylinder 1. The microcontroller inside the acidity or alkalinity detector 14 can activate the speaker 15 to sound an alarm. When performing acid immersion on items, place the items to be immersed in the inner frame 7, then insert the inner frame 7 into the outer cylinder 1, and then cover with the cover plate 20. At the top of the outer cylinder 1, the cover plate 20 seals the top of the outer cylinder 1 and the inner frame 7. The items are acid-soaked by the acid solution inside the outer cylinder 1. After the acid soaking is completed, the inner frame 7 is pulled out of the outer cylinder 1. During the pulling process, the lime water in the water tank 8 is pumped out by the water pump 9 and sprayed out through the water spray shell 10. The lime water sprayed out through the water spray shell 10 washes the surface of the inner frame 7, washing away the residual acid solution on its surface. The water generated by rinsing is blocked by the guide ring plate 2 and flows along the guide ring plate 2 and then into the guide shell 4 through the water flow hole 3. Under the guidance of the guide shell 4, it flows into the collection box 5 for collection.

[0026] In summary, this laboratory acid cylinder with leakage alarm function, through the bottom shell 12, fixing block 13, pH meter 14, speaker 15, and second drain valve 16, solves the problem that during use, the device can only rinse the inner wall of the outer cylinder, and the bottom of the acid cylinder will corrode during long-term use. Corrosion inside the acid cylinder will cause the acid inside to leak out, and the device cannot alarm after the acid leaks out, which is detrimental to the personal safety of the staff.
