Description

Technical Field

[0001] The utility model belongs to the technical field of liquid preparation preparation, and specifically relates to a liquid preparation purification device. Background Art

[0002] Purification of liquid preparations is a common step in some biological and chemical experiments, removing impurities to improve the purity of the active ingredients in the solution. For example, in the pharmaceutical industry, purified drug solutions contain fewer impurities, enabling precise efficacy and reducing the risk of side effects. In the electronics industry, purified chemical solutions used in chip manufacturing ensure chip performance and quality, preventing problems such as short circuits caused by impurities.

[0003] During the purification process, extraction, precipitation, and centrifugation are often used. The appropriate precipitant is selected based on the chemical properties of the target component and impurities. The precipitant reacts chemically with the impurities to form an insoluble precipitate, which is then separated from the target component. The supernatant is then removed to obtain the purified solution preparation.

[0004] However, in the existing operation of removing the supernatant, many experimenters use the method of direct pouring or using a syringe to draw out the supernatant. Although this can achieve the effect of separation, it is also easy to remove some impurities, causing contamination of the supernatant and reducing the purity of the supernatant. Therefore, how to efficiently separate the supernatant is an urgent problem to be solved. Utility Model Content

[0005] The purpose of this utility model is to provide a liquid preparation purification device, which can seal the impurities precipitated at the bottom of the test tube when taking the supernatant, so as not to cause contamination to the supernatant when separating it.

[0006] The technical solutions adopted in this application are as follows:

[0007] A liquid preparation purification device includes a suction cylinder and a base, the suction cylinder and the base correspond to each other, the bottom end of the suction cylinder is fixedly connected to a sealing block, the side wall of the sealing block is arranged to be inclined downward, the bottom end of the sealing block is provided with a circular groove, the side wall of the circular groove is provided with a through hole, the through hole extends to the upper end surface of the sealing block, and a one-way valve is installed in the through hole, the bottom surface of the sealing block is provided with a filter assembly at the circular groove, the side wall of the sealing block is fixedly connected to a rubber sleeve, the inner cavity of the suction cylinder is provided with a push rod, the top end of the push rod passes through the suction cylinder and is movably connected to the suction cylinder, the bottom end of the suction cylinder is fixedly connected to a piston, and the side wall of the suction cylinder is fixedly connected to a horizontal tube near the bottom end.

[0008] The side wall of the piston is equipped with a plurality of sealing rings, and the sealing rings are against the side wall of the suction cylinder.

[0009] The inner wall of the base has the same inclination as the side wall of the blocking block, and a plurality of protrusions are fixedly connected to the inner wall of the base, and the blocking block abuts against the protrusions.

[0010] The filter assembly includes a first magnetic ring fixedly connected to the bottom end surface of the blocking block, a second magnetic ring is adsorbed on the lower side of the first magnetic ring, and a filter gauze is arranged between the first magnetic ring and the second magnetic ring.

[0011] A collecting groove is provided on the bottom surface of the inner cavity of the base, and the collecting groove corresponds to the circular groove.

[0012] There are a number of through holes, and the through holes are distributed in a ring array.

[0013] The technical effects achieved by this utility model are:

[0014] The present invention is a practical liquid preparation purification equipment. Through the mutual cooperation between the suction cylinder, the blocking block, the filter component and the through hole, before separating the supernatant, the blocking block is first inserted into the test tube using the suction cylinder, and the supernatant enters the upper side of the blocking block through the through hole to facilitate the separation of the supernatant and impurities. The suction force of the piston is then used to extract the active supernatant to avoid the supernatant being contaminated by impurities, thereby effectively improving the separation purity of the supernatant.

[0023] In order to make the purpose and advantages of this utility more clear, the utility is described in detail below with reference to the embodiments. It should be understood that the following text is only used to describe one or several specific implementation methods of this utility and does not strictly limit the scope of protection specifically requested by this utility.

[0024] like Figures 1-6 As shown, a liquid preparation purification device includes a suction cylinder 1 and a base 2, the suction cylinder 1 and the base 2 correspond to each other, the bottom end of the suction cylinder 1 is fixedly connected to a sealing block 13, the side wall of the sealing block 13 is inclined downward, the bottom end of the sealing block 13 is provided with a circular groove 3, the side wall of the circular groove 3 is provided with a through hole 4, the through hole 4 extends to the upper end surface of the sealing block 13, and a one-way valve 16 is installed in the through hole 4. A filter assembly is provided on the bottom surface of the sealing block 13 at the circular groove 3, and a rubber sleeve 8 is fixedly connected to the side wall of the sealing block 13. A push rod 9 is provided in the inner cavity of the suction cylinder 1, and the top end of the push rod 9 passes through the suction cylinder 1 and is movably connected to it. The bottom end of the suction cylinder 1 is fixedly connected to a piston 10, and the side wall of the suction cylinder 1 is fixedly connected to a horizontal tube 12 near the bottom end.

[0025] like Figure 6 As shown, the sidewall of the piston 10 is equipped with a plurality of sealing rings 11, which abut against the sidewall of the suction cylinder 1. The provision of the sealing rings 11 can enhance the sealing and friction between the piston 10 and the inner wall of the suction cylinder 1. The principle here can be understood as the principle of syringes, which belongs to the prior art and will not be described in detail in this solution.

[0026] like Figure 1 and Figure 2 As shown, the inner wall of the base 2 and the side wall of the blocking block 13 have the same inclination, and a plurality of protrusions 14 are fixedly connected to the inner wall of the base 2 , and the blocking block 13 abuts against the protrusions 14 .

[0027] like Figure 4 As shown, the bottom surface of the inner cavity of the base 2 is provided with a collection groove 15, corresponding to the circular groove 3. There are multiple through-holes 4, distributed in a circular array. When the blocking block 13 enters the test tube, the supernatant can flow evenly from the multiple through-holes 4 to the upper side of the blocking block 13, increasing the fluidity of the supernatant. The one-way valve 16 prevents the supernatant from flowing backward.

[0028] Among them, the base 2 is used to support the blocking block 13 and the suction tube 1. When the suction tube 1 is not in use or after use, it can be placed vertically in the base 2. If liquid adheres to the through hole 4 and the circular groove 3, it can be collected by the collection groove 15; the protrusion 14 can reduce the contact area between the blocking block 13 and the base 2 to prevent contamination of the suction tube 1.

[0029] like Figure 3 and Figure 5As shown, the filter assembly includes a first magnetic ring 5 fixedly connected to the bottom end face of the blocking block 13, a second magnetic ring 6 is adsorbed on the lower side of the first magnetic ring 5, and a filter gauze 7 is provided between the first magnetic ring 5 and the second magnetic ring 6.

[0030] Among them, by setting up a filter component, when the blocking block 13 descends in the supernatant, the large particle impurities or flocculent impurities suspended in the supernatant can be filtered to further ensure the cleanliness of the supernatant; in addition, the first magnetic ring 5 and the second magnetic ring 6 are used to fix the filter gauze 7, which can facilitate the replacement and cleaning of the filter gauze 7. The filter gauze 7 can be disposable or non-disposable.

[0031] The working principle of the utility model is as follows: after the reagents and impurities in the test tube are separated, the impurities are deposited at the bottom of the test tube, and then the sealing block 13 is inserted into the test tube through the suction tube 1, and the rubber sleeve 8 is used to fit the inner wall of the test tube for sealing. When the sealing block 13 enters the supernatant, the supernatant on the lower side of the sealing block 13 enters the circular groove 3 and enters the upper side of the sealing block 13 through the through hole 4. When the sealing block 13 is close to the position where the impurities are deposited, stop pushing the suction tube 1, and then pull the push rod 9 to drive the piston 10 to move upward. The piston 10 sucks the supernatant on the upper side of the sealing block 13 into the interior of the suction tube 1. At this time, the one-way valve 16 is in a closed state, and the impurities on the lower side of the sealing block 13 will not be lifted by the suction force. After the supernatant is absorbed, the suction tube 1 and the sealing block 13 are taken out to obtain a pure liquid solution.

[0032] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this application shall be implemented in accordance with conventional means in the art unless otherwise specified or limited.
