TECHNICAL FIELD

[0001] The utility model belongs to the related technical field of ethanol washing device, specifically relates to a kind of ethanol washing device for cucurbituril compound preparation. BACKGROUND

[0002] Cucurbituril compound has potential application value in many fields. In its preparation process, the product often contains impurities, which need to be purified by effective washing device. Traditional washing method may have low efficiency, insufficient washing and other problems. Ethanol, as a commonly used washing solvent, has good solubility and volatility. Therefore, it is of great significance to develop ethanol washing device specially for cucurbituril compound preparation, which can accurately control the washing conditions such as temperature, washing time and ethanol dosage, so as to improve the purity and yield of cucurbituril compound, and meet the demand of scientific research and industrial production for high quality products.

[0003] In the traditional washing device, the placement of filter paper may not fit tightly due to the shape of filter paper, the smoothness of inner wall of funnel and other factors, resulting in gaps and lack of structure to compact pores, and part of the filtered material may leak into the beaker below. UTILITY MODEL CONTENT

[0004] The utility model aims at providing a kind of ethanol washing device for cucurbituril compound preparation to solve the problem that in the traditional washing device, the placement of filter paper may not fit tightly due to the shape of filter paper, the smoothness of inner wall of funnel and other factors, resulting in gaps and lack of structure to compact pores, and part of the filtered material may leak into the beaker below.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: an ethanol washing device for cucurbituril compound preparation, comprising a conical funnel and a drop-in tube arranged at the lower side of the conical funnel, a beaker arranged at the lower side of the drop-in tube;

[0006] A filter paper is arranged at the upper side of the conical funnel;

[0007] A sealing sleeve is arranged at the lower side of the drop-in tube, and a connecting tube is arranged at the upper right side of the drop-in tube;

[0008] A sealing plug is arranged at the inner side of the connecting tube, and a needle rod is arranged at the upper right side of the sealing plug;

[0009] A threaded ring is arranged at the upper side of the conical funnel, and a plastic sealing film is arranged at the upper side of the threaded ring.

[0010] Preferably, the threaded ring is connected to the upper side of the conical funnel through threaded connection, and a sealing ring is arranged at the connection position of the threaded ring and the conical funnel for sealing treatment.

[0011] Preferably, the connecting pipe is communicated with the dropping pipe, and an air cavity is arranged at the inner side of the middle of the connecting pipe.

[0012] Preferably, a plurality of sealing rings are arranged at the connection position of the sealing plug and the inner wall of the air cavity, and the sealing plug is connected to the needle rod through threaded connection.

[0013] Preferably, the sealing plug can move in the air cavity, the sealing sleeve is connected to the lower side of the dropping pipe through threaded connection, and a sealing ring is arranged at the inner side of the sealing sleeve for sealing treatment.

[0014] Preferably, the conical funnel is connected to the beaker through the dropping pipe by means of plug-in connection, and the plastic sealing film is transparent in color.

[0015] Compared with the prior art, the ethanol washing device for preparing cucurbituril compounds has the following beneficial effects:

[0016] 1. The sealing and compaction of the filter paper effectively blocks the pores between the filter paper and the inner wall of the conical funnel, and the possible gaps at the communication position of the dropping pipe and the conical funnel. For the washing process of cucurbituril compounds, it can be ensured that only the liquid filtered by the filter paper can enter the dropping pipe, greatly improving the integrity of the filtration. The impurities are maximally intercepted on the filter paper, ensuring the purity of cucurbituril compounds after washing.

[0017] 2. The precise sealing and filter paper compaction structure enables the entire filtration and washing process to be carried out under relatively stable and controllable conditions. Each time the washing operation is performed, as long as the sealing and compaction device is operated according to the same steps, a relatively consistent filtration effect can be obtained.

[0018] 3. The position of the sealing plug in the air cavity is adjusted by controlling the degree of extraction of the needle rod, thereby changing the air pressure and the pressure of the plastic sealing film on the filter paper. This design allows the operator to flexibly adjust the compaction degree of the filter paper according to the actual situation. For example, when the cucurbituril compound particles to be washed are small and require tighter filtration, the air pressure can be increased to make the filter paper adhere more tightly to the inner wall of the funnel; when the filtration speed is too slow to affect the experimental efficiency, the air pressure can be appropriately reduced to increase the filtration speed. This flexibility can better adapt to different experimental requirements and sample characteristics. BRIEF DESCRIPTION OF DRAWINGS

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides, for example Figures 1-5 An ethanol washing apparatus for preparing cucurbita urea compounds is shown, comprising a conical funnel 2 and a dropper 9 disposed at the lower side of the conical funnel 2, and a beaker 1 disposed at the lower outer side of the dropper 9.

[0027] A filter paper 8 is provided at the upper inner position of the conical funnel 2;

[0028] A sealing sleeve 3 is provided at the lower side of the drip tube 9, and a connecting tube 4 is provided at the upper right side of the drip tube 9;

[0029] A sealing plug 10 is provided on the inner side of the connecting tube 4, and a needle rod 5 is provided on the upper right side of the sealing plug 10.

[0030] A threaded ring 6 is provided at the upper outer position of the conical funnel 2, and a plastic sealing film 7 is provided at the upper position of the threaded ring 6.

[0031] In this embodiment, first, the operator will be washed cucurbituril compound placed in the conical funnel 2 inside the prepared filter paper 8. Then, the appropriate amount of ethanol slowly poured into the conical funnel 2, ethanol will be in full contact with cucurbituril compound, the impurities contained in the solution and entrainment.

[0032] Under the action of gravity, the ethanol solution containing impurities will be through the filter paper 8, along the conical funnel 2 below the drop tube 9 down the flow, eventually into the drop tube 9 placed on the side of the beaker 1.

[0033] Complete a ethanol and filtration, if you feel not enough washing, can repeat the above operation to add ethanol, multiple washing cucurbituril compound, until the impurities removal degree to achieve the desired results.

[0034] The principle is to use the filter paper 8 filter characteristics, it has a large number of small pores, can allow the liquid and soluble small molecule impurities, while cucurbituril compound solid particles due to the relatively large particle size and other reasons can not pass through the filter paper 8, thus achieving the preliminary separation of solid and liquid, to remove impurities.

[0035] The conical funnel 2 to a containing and guiding the flow of liquid, so that the ethanol solution after filtration through the filter paper 8, can along its shape smoothly through the drop tube 9 to the beaker 1. And the beaker 1 as a receiving container, used to collect from the drop tube 9 flow down the ethanol solution containing impurities, facilitate subsequent observation of the washing situation and centralized processing of the collected waste liquid operation, the whole device through such settings to complete the ethanol washing process of cucurbituril compound.

[0036] As shown in Figures 1-5 The threaded ring 6 can be connected to the upper side of the conical funnel 2 by threaded connection, and the threaded ring 6 and the conical funnel 2 are sealed by the sealing ring at the connection position. The connecting tube 4 is connected with the drop tube 9, and the air cavity 11 is arranged in the middle of the connecting tube 4. The sealing plug 10 is connected with the needle rod 5 by threaded connection, and can move in the air cavity 11. The sealing sleeve 3 is connected with the drop tube 9 by threaded connection, and the sealing sleeve 3 is sealed by the sealing ring arranged in the inner side. The conical funnel 2 is connected with the beaker 1 by plug-in connection through the drop tube 9, and the plastic sealing film 7 is transparent.

[0037] Preferably, after the operator installs the filter paper 8 in the conical funnel 2, in order to solve the problem that the filter paper 8 has pores with the inner wall of the funnel and the drop tube 9 and the conical funnel 2 may not be completely blocked, causing some filtered materials to leak, the operator should first seal.

[0038] The sealing sleeve 3 is installed to the lower side of the dropping pipe 9 by screwing, so as to tightly adhere and seal the lower end of the dropping pipe 9; meanwhile, the screw ring 6 is connected to the upper side of the conical funnel 2 by screwing, and the sealing ring is used to seal the connection position, so as to seal the internal space formed by the conical funnel 2 and the dropping pipe 9.

[0039] Then, the operator operates in the connecting pipe 4 to draw out the needle rod 5. Since the needle rod 5 is connected to the sealing plug 10 by screwing, the needle rod 5 will drive the sealing plug 10 to move in the air cavity 11 arranged in the middle of the connecting pipe 4 when the needle rod 5 is drawn out. With the movement of the sealing plug 10, the air pressure in the air cavity 11 and the whole sealed conical funnel 2 and dropping pipe 9 will be changed, and the suction effect is formed in the relatively sealed space, so that the plastic sealing film 7 is pressed to the lower side under the influence of the air pressure suction. Since the plastic sealing film 7 is arranged on the upper side of the conical funnel 2, the filter paper 8 placed in the conical funnel 2 will be pressed during the downward pressing process of the plastic sealing film 7, so that the filter paper 8 can be more closely adhered to the inner wall of the conical funnel 2, and the original pores are fully compacted, thereby reducing the possibility of the filtered material entering the dropping pipe 9 and then flowing into the beaker 1 through the pores, and ensuring the accuracy and effectiveness of the filtering and washing process.

[0040] Finally, it should be noted that the above only describes the preferred embodiments of the present application, and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or equivalently replace some of the technical features, and any modification, equivalent replacement or improvement made within the spirit and principles of the present application shall be included in the protection scope of the present application.
