Description

Technical Field

[0001] The invention relates to the field of auxiliary structures of condensers, and in particular to an automatic liquid supply device for condensers used in experiments. Background Art

[0002] The traditional manual liquid supply of condenser tubes relies on manual operation, which has problems such as uneven liquid supply and unstable flow control, affecting the accuracy and repeatability of experimental results. In manual liquid supply, manual adjustment of valves is cumbersome, which is easy to introduce human errors, and it is impossible to achieve a continuous and stable liquid supply state. Especially in long-term experiments, the stability of liquid supply is difficult to guarantee, resulting in large fluctuations in experimental data.

[0003] If the liquid is supplied by the natural flow of gravity, the advantage is that the liquid supply structure will be relatively simple, but the disadvantage is that the liquid supply speed is greatly affected by the liquid level and is difficult to control accurately. If the coolant needs to be replaced during the actual liquid supply process, the operator still needs to manually disassemble the condenser tube, which is cumbersome and easy to cause coolant leakage. It is difficult to meet the high-precision and high-repeatability experimental requirements, which restricts the experimental efficiency. Summary of the invention

[0004] In view of the above technical problems in the related art, the present invention proposes an automatic liquid supply device for a condenser for experiments, which can overcome the above shortcomings of the prior art.

[0005] To achieve the above technical objectives, the technical solution of the present invention is implemented as follows: An automatic liquid supply device for a condenser for experiments comprises a condenser, wherein a clamping assembly is sleeved on the condenser, a liquid supply slider is inserted into the right end of the clamping assembly, the liquid supply slider is slidably connected to a slide groove assembly, the lower part of the slide groove assembly is detachably connected to the upper part of an anti-overflow box, and the liquid supply slider and the slide groove assembly are respectively provided with overflow liquid guide holes that can guide overflowed liquid to the anti-overflow box.

[0006] Preferably, the condenser is provided with a liquid inlet at the top and a liquid outlet at the bottom, the top of the right end of the clamping assembly is provided with a first joint and a second joint, and the side of the right end is provided with a liquid supply joint and a liquid discharge joint; The first joint is connected to the liquid supply joint, the second joint is connected to the liquid discharge joint, and the liquid inlet and the liquid outlet are connected to the first joint and the second joint respectively through pipelines; The liquid supply slider is provided with a slider connecting pipe which is plugged into the liquid supply connector and the liquid discharge connector respectively.

[0007] Preferably, the clamping assembly comprises a left clamping part and a right clamping part which are detachably connected, and after the left clamping part and the right clamping part are connected, a clamping hole is formed for the condenser tube to vertically pass through the hole; The first joint, the second joint, the liquid supply joint, and the liquid discharge joint are all located on the right clamping part.

[0008] Preferably, corresponding threaded holes are respectively provided at the docking ends of the left clamping part and the right clamping part, and the left clamping part and the right clamping part are threadedly connected through the corresponding threaded holes, bolts or screws.

[0009] Preferably, two sealing rubber rings are respectively provided on the liquid supply joint and the liquid discharge joint.

[0010] Preferably, the liquid supply slider includes a slider body, buckle pieces are respectively snap-connected to the front and rear ends of the slider body, and an anti-disengagement spring is connected between the two buckle pieces. The anti-disengagement spring can fix the two buckle pieces on the slider body.

[0011] Preferably, lower slider grooves for accommodating the buckle pieces are provided at the front and rear ends of the slider body, and an upper slider groove for accommodating the anti-disengagement spring is provided at the top of the slider body. The anti-disengagement spring can fix the two buckle pieces in the lower slider grooves.

[0012] Preferably, hanging fasteners are respectively passed through the buckle pieces, hanging holes are provided on the hanging fasteners, and the two ends of the anti-disengagement spring are respectively hung on the hanging holes of the two hanging fasteners. Threaded holes can be provided on the buckle pieces, and external threads can be provided on the hanging fasteners, so as to realize the threaded connection between the hanging fasteners and the buckle pieces. Smooth holes through which the hanging fasteners can pass can also be provided on the buckle pieces.

[0013] Preferably, the chute assembly includes a chute top plate, a chute bottom plate and chute vertical plates; The rear end of the chute top plate and the rear end of the chute bottom plate are connected by the chute vertical plates, and the length of the chute top plate is greater than the length of the chute bottom plate; Lower baffle plates are provided on the left and right sides of the chute top plate, and upper baffle plates are provided on the left and right sides of the chute bottom plate; The chute top plate, the chute bottom plate, the lower baffle plates of the top plate and the upper baffle plates of the bottom plate jointly form a limiting chute capable of limiting the slider body and the buckle pieces, and the liquid supply slider is slidably connected with the limiting chute. During implementation, the lower baffle plates of the top plate and the upper baffle plates of the bottom plate jointly limit the slider body and the buckle pieces respectively from the left and right sides. When the liquid supply slider slides out of the limiting chute, that is, slides to the position where the length of the chute top plate exceeds the length of the chute bottom plate, the buckle pieces can unlock the anti-disengagement spring from the buckle pieces due to the loss of the limiting effect from the lower baffle plates of the top plate and the upper baffle plates of the bottom plate, so that the buckle pieces can be easily removed from the slider body.

[0014] Preferably, a box connecting plate is provided on the upper part of the anti-overflow box, corresponding threaded holes are respectively provided on the lower part of the chute assembly and the box connecting plate, and the chute assembly and the anti-overflow box are threadedly connected through the corresponding threaded holes, screws or bolts.

[0015] Preferably, the bottom of the overflow prevention box is provided with an overflow outlet, which can be connected to a liquid container or other drainage facilities through a guide pipe.

[0016] Beneficial effects of this design: This product is divided into five modules, namely, condenser, clamping assembly, liquid supply slider, slide assembly, and anti-overflow box. The liquid supply slider is assembled by a slider body, two clips and an anti-detachment spring, and the two clips are connected and fixed to the slider body by an anti-detachment spring. In the slider body, the slide top plate, the slide bottom plate, the lower baffle of the top plate, and the upper baffle of the bottom plate together form a limiting slide that can limit the slider body and the clip, and the liquid supply slider is slidably connected to the limiting slide.

[0017] When the liquid supply slider is slidably connected to the limiting slide groove, the buckle is limited by the limiting slide grooves on the left and right sides, thereby ensuring that the buckle is in a locked state; when the liquid supply slider slides to the position where the length of the slide groove top plate exceeds the length of the slide groove bottom plate, that is, slides out of the limiting slide groove, the buckle recovers to the open state due to the loss of the limiting effect of the baffle plate under the top plate and the baffle plate on the bottom plate, the anti-detachment tension spring can be released from the buckle, so that the buckle can be easily removed from the slider body.

[0018] In the clamping assembly, the liquid supply joint and the liquid discharge joint can be designed with double sealing using high-quality sealing rubber rings. In the liquid supply mode, the sealing rubber rings can tightly seal the interface to prevent liquid leakage and avoid the intrusion of external impurities, thus 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.

[0019] The clamping assembly is connected to the liquid supply slider through the liquid supply joint and the liquid discharge joint. When the liquid supply slider slides in the limiting slide groove in the slide groove assembly, the fastener is in a locked state due to the tension of the anti-detachment tension spring and the limiting effect of the limiting slide groove. This not only ensures the stability of the connection, but also has a simple structural design. When disassembling, you only need to slide the liquid supply slider out of the limiting slide groove. The fastener can be detached from the slider body due to the loss of the limiting effect of the limiting slide groove, which greatly improves the automatic liquid supply efficiency and operational convenience.

[0020] The bottom of the slide assembly can be connected to an anti-overflow box, and the liquid supply slider, slide assembly, etc. can be provided with overflow guide holes, which effectively prevents liquid overflow and splashing and ensures a clean laboratory environment.

[0021] Compared with the prior art, the present product has the following advantages: (A) It realizes the automation of the liquid supply of the condenser tube, reducing the manual operation burden of the experimenters. (B) The system structure is simple, easy to install and maintain, and is applicable to a variety of experimental scenarios. (C) It effectively reduces the risk of coolant leakage, improving the consistency and reliability of experimental data. (D) It significantly improves the experimental efficiency, shortens the experimental cycle, and optimizes the laboratory work process. Brief Description of the Drawings

[0047] 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 pipes. One slider connector 3011 corresponding to the liquid supply joint 2023 can be directly connected to the liquid container 10 through a liquid guide pipe. The other slider connector 3011 corresponding to the liquid discharge joint 2024 is connected to the inlet of the three-way valve 7 through a liquid guide pipe. The first outlet of the three-way valve 7 is connected to the liquid container 10 through a liquid supply pump 8 and a liquid guide pipe, and the second outlet of the three-way valve 7 is connected to the liquid container 10 through a liquid discharge pump 9 and a liquid guide pipe. The condenser liquid supply and discharge technology composed of the liquid supply pump 8, the liquid discharge pump 9, the liquid guide pipe, the liquid container 10, the three-way valve 7, etc. is the prior art in this field and will not be elaborated here.

[0048] When the chemical synthesis starts, it enters the condenser liquid supply mode of the condenser tube 1 to condense the flask.

[0049] In the discharge mode, it is no longer necessary to condense the flask, and the liquid in the condenser 1 and the matching structure needs to be discharged, so the discharge pump 9 is started, and the discharge pump 9 drives the residual liquid remaining in the condenser 1, etc. to flow back to the liquid container 10 through the liquid outlet 102, the second joint 2022, the discharge joint 2024, the corresponding discharge slider pipe 3011, the three-way valve 7, and the discharge pump 9.
