Description

An automatic liquid supply device for experimental condenser tubes Technical Field

[0001] This utility model relates to the field of auxiliary structures for condenser tubes, and more specifically, to an automatic liquid supply device for condenser tubes used in experiments. Background Technology

[0002] Traditional manual liquid supply in condenser tubes relies on manual operation, which suffers from uneven liquid supply and unstable flow control, affecting the accuracy and repeatability of experimental results. Furthermore, manual valve adjustment is cumbersome, prone to human error, and cannot achieve a continuous and stable liquid supply. Especially during long-term experiments, the stability of the liquid supply is difficult to guarantee, leading to significant fluctuations in experimental data.

[0003] Utilizing gravity to allow the liquid to flow naturally for supply has the advantage of a relatively simple supply structure. However, it also has the disadvantage that the supply speed is greatly affected by the liquid level, making precise control difficult. Furthermore, if coolant replacement is needed during the actual supply process, manual operation is still required, involving the manual disassembly of the condenser tubes. This cumbersome process is prone to coolant leakage, making it difficult to meet the requirements of high-precision and highly repeatable experiments and thus limiting experimental efficiency. Summary of the Invention

[0004] In view of the above-mentioned technical problems in related technologies, this utility model proposes an automatic liquid supply device for experimental condenser tubes, which can overcome the above-mentioned shortcomings of the prior art.

[0005] To achieve the above-mentioned technical objectives, the technical solution of this utility model is as follows:

[0006] An automatic liquid supply device for condenser tubes used in experiments includes a condenser tube, a clamping assembly sleeved on the condenser tube, a liquid supply slider inserted into the right end of the clamping assembly, the liquid supply slider being slidably connected to a chute assembly, the lower part of the chute assembly being detachably connected to the upper part of an overflow box, and the liquid supply slider and the chute assembly being respectively provided with overflow guide holes that can guide overflowing liquid to the overflow box.

[0007] Preferably, the condenser tube has an inlet at the top and an outlet at the bottom, and the clamping assembly has a first connector and a second connector at the top right end and a supply connector and a drain connector on the side right end.

[0008] The first connector is connected to the liquid supply connector, the second connector is connected to the liquid drain connector, and the liquid inlet and liquid outlet are respectively connected to the first connector and the second connector through pipelines;

[0009] The liquid supply slider is provided with slider connecting pipes that are respectively inserted into the liquid supply connector and the liquid discharge connector.

[0010] Preferably, the clamping assembly includes a detachably connected left clamping part and a right clamping part, and the left clamping part and the right clamping part are connected to form a clamping hole for the condenser tube to pass through vertically.

[0011] The first connector, the second connector, the liquid supply connector, and the liquid drain connector are all located on the right clamping part.

[0012] Preferably, the mating ends of the left clamping part and the right clamping part are respectively provided with corresponding threaded holes, and the left clamping part and the right clamping part are threadedly connected by corresponding threaded holes, bolts or screws.

[0013] Preferably, the liquid supply connector and the liquid drain connector are each provided with two sealing rubber rings.

[0014] Preferably, the liquid supply slider includes a slider body, with snap-fit ​​fasteners at both ends of the slider body, and an anti-detachment tension spring connecting the two snap-fit ​​fasteners. The anti-detachment tension spring can fix the two snap-fit ​​fasteners to the slider body.

[0015] Preferably, the slider body has lower grooves at both ends for accommodating the latching members, and a top groove at the top for accommodating the anti-detachment spring. The anti-detachment spring can fix the two latching members in the lower grooves of the slider.

[0016] Preferably, each of the snap fasteners has a hook fastener inserted through it, and each hook fastener has a hook hole. The two ends of the anti-detachment tension spring are respectively hooked onto the hook holes of the two hook fasteners. The snap fasteners may have threaded holes, and the hook fasteners may have external threads, thereby realizing a threaded connection between the hook fasteners and the snap fasteners. The snap fasteners may also have smooth holes for the hook fasteners to pass through.

[0017] Preferably, the chute assembly includes a chute top plate, a chute bottom plate, and a chute vertical plate;

[0018] The rear end of the top plate of the chute and the rear end of the bottom plate of the chute are connected by the vertical plate of the chute, and the length of the top plate of the chute is greater than the length of the bottom plate of the chute.

[0019] The top plate of the chute is provided with a lower baffle on the left and right sides, and the bottom plate of the chute is provided with an upper baffle on the left and right sides.

[0020] The top plate, bottom plate, lower baffle of the top plate, and upper baffle of the bottom plate together form a limiting groove that restricts the slider body and the fastener, and the liquid supply slider is slidably connected to the limiting groove. In implementation, the lower baffle of the top plate and the upper baffle of the bottom plate together restrict the slider body and the fastener from the left and right sides respectively. When the liquid supply slider slides out of the limiting groove, i.e., to a position where the length of the top plate exceeds the length of the bottom plate, the fastener loses its limiting effect from the lower baffle of the top plate and the upper baffle of the bottom plate, and the anti-detachment spring on the fastener can be released, thus allowing the fastener to be easily removed from the slider body.

[0021] Preferably, the upper part of the anti-overflow box is provided with a box connecting plate, and the lower part of the slide assembly, the box connecting plate and the slide are respectively provided with corresponding threaded holes. The slide assembly and the anti-overflow box are threadedly connected by the corresponding threaded holes, screws or bolts.

[0022] Preferably, the bottom of the overflow box is provided with an overflow outlet. The overflow outlet can be connected to a liquid container or other drainage facility via a guide pipe.

[0023] The beneficial effects achieved by this design are as follows: This product is divided into five main modules: condenser tube, clamping assembly, liquid supply slider, slide groove assembly, and anti-overflow box. The liquid supply slider is assembled from a slider body, two snap fasteners, and an anti-detachment spring. The two snap fasteners are connected and fixed to the slider body by the anti-detachment spring. In the slider body, the slide groove top plate, slide groove bottom plate, top plate lower baffle, and bottom plate upper baffle together form a limiting slide groove that can limit the slider body and snap fasteners, and the liquid supply slider is slidably connected to the limiting slide groove.

[0024] When the liquid supply slider is slidably connected to the limiting groove, the fastener is limited by the limiting grooves on both the left and right sides, thus ensuring that the fastener is in a locked state. When the liquid supply slider slides to a position where the length of the top plate of the groove exceeds the length of the bottom plate of the groove, that is, when it slides out of the limiting groove, the fastener returns to the open state because it loses the limiting effect from the bottom baffle of the top plate and the bottom plate baffle. The anti-detachment tension spring can be released from the fastener, so that the fastener can be easily removed from the slider body.

[0025] In the clamping assembly, the liquid supply connector and the liquid drain connector can be designed with high-quality sealing rings for double sealing. In liquid supply mode, the sealing rings can completely seal the interface, preventing liquid leakage, avoiding the intrusion of external impurities, ensuring the stability and reliability of the entire product operation, and preventing accidents and hidden dangers caused by liquid leakage during the liquid supply process.

[0026] The clamping assembly is connected to the liquid supply slider via a liquid supply connector and a liquid drain connector. When the liquid supply slider slides in the limiting groove of the sliding groove assembly, the buckle is locked due to the tension of the anti-disengagement spring and the limiting effect of the limiting groove. This not only ensures the stability of the connection, but also has a simple structural design. When disassembling, simply slide the liquid supply slider out of the limiting groove. The buckle can then be released from the slider body because it loses the limiting effect of the limiting groove, which greatly improves the efficiency of automatic liquid supply and the convenience of operation.

[0027] The bottom of the chute assembly can be connected to an overflow box, and the liquid supply slider, chute assembly, etc. can all be equipped with overflow guide holes, which effectively prevents liquid from overflowing and splashing, ensuring a clean laboratory environment.

[0028] Compared to existing technologies, this product has the following advantages: (A) It automates the cooling coil supply, reducing the manual operation burden on laboratory personnel. (B) The system has a simple structure, is easy to install and maintain, and is suitable for various experimental scenarios. (C) It effectively reduces the risk of coolant leakage and improves the consistency and reliability of experimental data. (D) It significantly improves experimental efficiency, shortens the experimental cycle, and optimizes laboratory workflow. Attached Figure Description

[0042] As shown in Figures 1-11, in order to facilitate understanding of the above technical solution of this utility model, the above technical solution of this utility model will be described in detail below through specific usage methods.

[0043] An automatic liquid supply device for condenser tubes used in experiments includes a condenser tube 1, a clamping assembly 2 sleeved on the condenser tube 1, a liquid supply slider 3 inserted into the right end of the clamping assembly 2, the liquid supply slider 3 being slidably connected to a sliding groove assembly 4, the lower part of the sliding groove assembly 4 being detachably connected to the upper part of an overflow box 5, and the liquid supply slider 3 and the sliding groove assembly 4 being respectively provided with overflow guide holes that can guide overflowing liquid to the overflow box 5.

[0045] The first connector 2021 is connected to the liquid supply connector 2023, the second connector 2022 is connected to the liquid drain connector 2024, and the liquid inlet 101 and the liquid outlet 102 are respectively connected to the first connector 2021 and the second connector 2022 through the pipeline 6.

[0046] The liquid supply slider 3 is provided with slider pipe 3011 that is respectively inserted into the liquid supply connector 2023 and the liquid discharge connector 2024.

[0047] In one possible embodiment, the clamping assembly 2 includes a detachably connected left clamping part 201 and a right clamping part 202, and the left clamping part 201 and the right clamping part 202, after being connected, form a clamping hole 203 through which the condenser tube 1 passes vertically.

[0048] The first connector 2021, the second connector 2022, the liquid supply connector 2023, and the liquid drain connector 2024 are all located on the right clamping part 202.

[0049] In one possible embodiment, the mating ends of the left clamping part 201 and the right clamping part 202 are respectively provided with corresponding threaded holes, and the left clamping part 201 and the right clamping part 202 are threadedly connected by corresponding threaded holes, bolts or screws.

[0050] In one possible embodiment, the liquid supply connector 2023 and the liquid drain connector 2024 are respectively provided with two sealing rubber rings 2025.

[0051] In one possible embodiment, the liquid supply slider 3 includes a slider body 301, with snap-fit ​​fasteners 302 respectively attached to the front and rear ends of the slider body 301, and an anti-detachment tension spring 303 connecting the two snap-fit ​​fasteners 302. The anti-detachment tension spring 303 can fix the two snap-fit ​​fasteners 302 onto the slider body 301.

[0052] In one possible embodiment, the slider body 301 has lower slider grooves 3012 at both its front and rear ends to accommodate the latching members 302, and a top slider groove 3013 at its top to accommodate the anti-detachment spring 303. The anti-detachment spring 303 can fix the two latching members 302 in the lower slider grooves 3012.

[0053] In one possible embodiment, the snap fasteners 302 are respectively fitted with hook fasteners 3021, each hook fastener 3021 having a hook hole. The anti-detachment tension spring 303 is hooked at both ends onto the hook holes of the two hook fasteners 3021. The snap fasteners 302 may have threaded holes, and the hook fasteners 3021 may have external threads, thereby achieving a threaded connection between the hook fasteners 3021 and the snap fasteners 302. Alternatively, the snap fasteners 302 may have smooth holes through which the hook fasteners 3021 pass.

[0054] In one possible embodiment, the chute assembly 4 includes a chute top plate 401, a chute bottom plate 402, and a chute vertical plate 403;

[0055] The rear ends of the top plate 401 and the bottom plate 402 of the chute are connected by the vertical plate 403 of the chute, and the length of the top plate 401 is greater than the length of the bottom plate 402 of the chute.

[0056] The top plate 401 of the chute is provided with a lower baffle 4012 on the left and right sides, and the bottom plate 402 of the chute is provided with an upper baffle 4021 on the left and right sides.

[0057] The top plate 401, bottom plate 402, lower baffle 4012, and upper baffle 4021 of the slide groove together form a limiting slide groove that limits the slider body 301 and the fastener 302, and the liquid supply slider 3 is slidably connected to the limiting slide groove. In implementation, the lower baffle 4012 and the upper baffle 4021 of the bottom plate together limit the slider body 301 and the fastener 302 from the left and right sides respectively. When the liquid supply slider 3 slides out of the limiting slide groove, that is, when the length of the top plate 401 exceeds the length of the bottom plate 402, the fastener 302 loses the limiting effect from the lower baffle 4012 and the upper baffle 4021 of the bottom plate, and the anti-detachment spring 303 can be released from the fastener 302, so the fastener 302 can be easily removed from the slider body 301.

[0058] In one possible embodiment, the upper part of the anti-overflow box 5 is provided with a box connecting plate 501, and the lower part of the slide assembly 4, the box connecting plate 501 and the corresponding threaded holes are respectively provided. The slide assembly 4 and the anti-overflow box 5 are threadedly connected by the corresponding threaded holes, screws or bolts.

[0059] In one possible embodiment, the bottom of the overflow box 5 is provided with an overflow outlet 502. The overflow outlet 502 can be connected to the liquid container 10 or other drainage facilities via a guide pipe.

[0060] Working principle: During implementation, the lower part of the condenser tube 1 is inserted into the flask. The two slider connectors 3011 are respectively connected to the liquid container 10 through liquid guide tubes. One slider connector 3011 corresponding to the liquid supply connector 2023 can be directly connected to the liquid container 10 through a liquid guide tube. The other slider connector 3011 corresponding to the drain connector 2024 is connected to the inlet of the three-way valve 7 through a liquid guide tube. The first outlet of the three-way valve 7 is connected to the liquid container 10 through the liquid supply pump 8 and the liquid guide tube, and the second outlet of the three-way valve 7 is connected to the liquid container 10 through the drain pump 9 and the liquid guide tube. The condenser tube liquid supply and drainage technology consisting of the liquid supply pump 8, the drain pump 9, the liquid guide tube, the liquid container 10, and the three-way valve 7 is existing technology in this field and will not be described in detail here.

[0061] At the start of chemical synthesis, the liquid enters the condenser tube 1 condensation supply mode to condense the flask. Driven by the supply pump 8, the liquid passes sequentially through the liquid container 10, the corresponding inlet slider connector 3011, the supply connector 2023, the first connector 2021, the inlet 101, the inside of the condenser tube 1, the outlet 102, the second connector 2022, the drain connector 2024, the corresponding drain slider connector 3011, the three-way valve 7, the supply pump 8, and back to the liquid container 10. This supply circulation path can be simplified as "liquid container 10 → inlet 101 → condenser tube 1 → outlet 102 → three-way valve 7 → supply pump 8 → liquid container 10", as shown on the left side of Figure 11. In the supply mode, the liquid circulates between the liquid container 10 and the condenser tube 1, and continuously exchanges heat with the flask while flowing in the condenser tube 1, thereby maintaining the flask temperature within a suitable range and achieving the condensation effect on the flask.

[0062] In the draining mode, condensation of the flask is no longer required. Instead, the liquid in the condenser tube 1 and its associated structure needs to be drained. Therefore, the draining pump 9 is started. The draining pump 9 drives the residual liquid in the condenser tube 1, etc., to flow back to the liquid container 10 through the outlet 102, the second connector 2022, the drain connector 2024, the corresponding draining slider connector 3011, the three-way valve 7, and the draining pump 9. This draining path can be simplified as "condenser tube 1 → outlet 102 → three-way valve 7 → draining pump 9 → liquid container 10", as shown on the right side of Figure 11.

[0063] In summary, thanks to the aforementioned unique technical solution, this product has the following advantages: (A) It automates the condenser supply, reducing the manual operation burden on laboratory personnel. (B) The system has a simple structure, is easy to install and maintain, and is suitable for various experimental scenarios. (C) It effectively reduces the risk of coolant leakage and improves the consistency and reliability of experimental data. (D) It significantly improves experimental efficiency, shortens the experimental cycle, and optimizes laboratory workflow.
