Description

Technical Field

[0001] The utility model relates to the field of solid-liquid separation equipment, in particular to simple and efficient solid-liquid separation equipment. Background Art

[0002] Simple and efficient solid-liquid separation technology and equipment is a key technology in both scientific research and industrial production. For example, separation of biologically active substances from solid raw materials in biopharmaceutical industrial production, separation of synthetic products from solid substrates in chemical companies, separation of active substance extracts from solid raw materials in food processing companies, separation of water from solid matrices (adsorbed impurities) after treatment operations in water treatment plants, etc. The following focuses on the application of magnetic particles and the current problems and solutions for the separation of magnetic separation liquid (liquid other than magnetic particles in magnetic suspension) and magnetic particles in magnetic suspension (mixture of magnetic particles and solution) in combination with the specific implementation methods of the utility model.

[0003] Magnetic particles are environmentally friendly, reusable and easy to recycle. For example, magnetic particles are an emerging type of magnetic nanomaterials that have a wide range of applications in many other fields such as environment, medicine, biology, agriculture and food. For example, magnetic nanomaterials have good application prospects in biomarkers, medical diagnosis, antimicrobial agents, cell markers for bioimaging, drug delivery systems, nanomedicines for the treatment of various diseases, and drinking water disinfection. In addition, magnetic particles can remove a wide range of pollutants, including drugs and drug-resistant pathogens, from wastewater and drinking water production and irrigation water. However, the magnetic particles and the magnetic separation liquid are still in the same container. The solid-liquid separation method commonly used in the prior art for magnetic suspensions is to rely on magnet adsorption of magnetic particles combined with the pouring method. This method only processes one sample at a time, cannot meet the high-throughput requirements, and is laborious to operate; in addition, the wall turbulence generated by the pouring method will inevitably cause serious loss of magnetic particles. These problems make the magnetic separation of magnetic separation liquids by magnet adsorption combined with the pouring method time-consuming, laborious and high-loss. Among them, the magnetic separation liquid transfer and collection technology directly affects the utilization efficiency and recovery rate of magnetic particles. Aiming at this key technology, Heilongjiang Chunjiarong Technology Co., Ltd. has designed a controllable vacuum liquid collection device, through which the magnetic particle recovery rate can reach more than 98%. Utility Model Content

[0004] The problem to be solved by the utility model is to provide a controllable vacuum liquid collecting device to complete the solid-liquid separation work, which is applicable to both high and low throughput samples.

[0005] To achieve the above-mentioned purpose, the utility model provides a controllable vacuum liquid collection device. The technical solution of the utility model is as follows: a controllable vacuum liquid collection device, comprising: a collection bottle (1), a sealing cover (2), a double-hole cover plate (3), an injection tube (4), an exhaust pipe (5), a speed control valve (6) and a liquid collection probe (7), see the attached figure of the specification for details.

[0006] Collection bottle (1): used to collect and store magnetic separation liquid (components other than magnetic particles). The collection bottle is generally 250 to 1000 mL.

[0007] Furthermore, the bottle cap of the collection bottle (1) includes a sealing cover (2) and a double-hole cover plate (3), and the sealing cover (2) can be made of polypropylene (PP), polytetrafluoroethylene (PTFE), aluminum alloy, stainless steel, etc., preferably polypropylene PP. It is used to seal the collection bottle. The double-hole cover plate (3) is provided with an injection hole (31) and an exhaust (release) hole (32). The outer end of the bottle of the injection hole (31) collection bottle is connected to the injection tube (4), and the inner end of the bottle of the injection hole (31) collection bottle is connected to a silicone hose of appropriate length, which is conducive to the collection of the injection liquid. Because the silicone hose of appropriate length in the collection bottle can prevent the liquid from entering the collection bottle and being sucked into the exhaust pipe, causing air path blockage. One end of the exhaust hole (32) is connected to the exhaust pipe (5), and the other end of the air pipe (5) is connected to the vacuum pumping device.

[0008] Furthermore, the sample injection tube (4) is connected to the sample injection hole (31) for transferring the liquid into the collection bottle. The exhaust pipe (5) is connected to the exhaust hole (32).

[0009] Furthermore, the sample inlet pipe (4) and the exhaust pipe (5) are silicone hoses or the like.

[0010] Furthermore, the exhaust pipe (5) is provided with a speed control valve (6), which controls the vacuum pressure in the collection bottle by adjusting the exhaust speed (or gas flow), thereby regulating the liquid collection speed, so as to avoid the magnetic particles being collected and lost due to the excessive vacuum pressure causing the liquid collection speed to be too fast, or the liquid collection speed to be too slow due to the vacuum pressure being too low, resulting in low collection efficiency.

[0011] The liquid collection probe (7) is connected to the end of the sample injection tube (4) and is used to collect liquid fractions in the solid-liquid system. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] A controllable vacuum liquid collecting device, comprising:

[0029] A collecting bottle (1), a sealing cover (2), a double-hole cover plate (3), an injection hole (31), an exhaust hole (32), an injection tube (4), an exhaust tube (5), a speed control valve (6) and a liquid collection probe (7).

[0030] The collecting bottle (1), the sealing cover (2), and the double-hole cover plate (3) are detachably sealed and connected, generally in the form of threaded connection. The sealing cover 2 is a component that matches the collecting bottle 1. The sealing cover 2 can be made of polypropylene, which has the advantages of being non-toxic, odorless, tasteless, heat-resistant, and chemically resistant. The collecting bottle 1 can be made of glass, polytetrafluoroethylene (PTFE), and stainless steel, and its volume varies according to the volume of the liquid to be separated. The double-hole cover plate 3 can be made of stainless steel, which has the advantages of being non-toxic, odorless, tasteless, heat-resistant, and chemically resistant. The connected assembly is placed in a stable place at room temperature for collecting and storing magnetic separation liquid (components other than magnetic particles in the magnetic suspension). The inner end of the sampling hole (31) of the double-hole cover plate (3) is connected to a silicone hose of appropriate length.

[0031] Furthermore, the two ends of the injection tube (4) are respectively connected to the injection hole (31) and the liquid collection probe (7). Different types of liquid collection probes (7) are selected according to actual conditions. Specifically, the injection tube 4 is a silicone hose, and the liquid collection probe 7 can use a flat-head stainless steel elongated needle. Different types of stainless steel needles can be selected according to actual operation needs, but the liquid collection probe is not limited to a flat-head stainless steel elongated needle.

[0032] Furthermore, both ends of the exhaust pipe (5) are connected to the exhaust hole (32) and the vacuum pumping device, respectively, and a speed control valve (6) is provided on the exhaust pipe (5). Specifically, the exhaust pipe 5 is a silicone hose, the vacuum pumping device can be a circulating water vacuum pump or a motor vacuum pump, and the speed control valve (i.e., flow rate regulator) can be a pulley-type infusion flow rate regulator, a Robert clamp infusion hose flow rate regulator, or a valve, but is not limited to a pulley-type infusion flow rate regulator, a Robert clamp infusion hose flow rate regulator, or a valve.

[0033] Furthermore, after the adsorption and aggregation of magnetic particles in the magnetic suspension are completed using a track-type rapid separation magnetic separation adsorption device independently developed by Heilongjiang Chunjiarong Technology Co., Ltd., a controllable vacuum liquid collection device of the utility model is used to achieve rapid collection of magnetic separation liquid in the magnetic suspension and enrichment of magnetic particles with high efficiency and high recovery rate.

[0034] The vacuum device is started, and when a negative pressure environment is formed in the collection bottle, the liquid collection probe (7) is inserted into the magnetic suspension container where the magnetic separation is completed, away from the magnetic particle gathering place, and the magnetic separation liquid enters the injection tube (4) due to the negative pressure, and then enters the collection bottle. After the magnetic separation liquid in the magnetic suspension container is completely removed, the liquid collection probe (7) is removed from the magnetic suspension container to complete the collection of the magnetic separation liquid in the magnetic suspension. In addition, during the magnetic separation liquid collection process, the liquid collection probe (7) is removed from the magnetic suspension container to suspend the solid-liquid separation operation of the magnetic suspension.

[0035] Furthermore, the speed control valve (6) adjusts the exhaust speed of the exhaust pipe (5) to a suitable flow rate until there are no magnetic particles in the collection bottle.

[0036] The novel design of this embodiment solves the problems of low solid-liquid separation efficiency and low recovery rate of magnetic suspension (magnetic particle suspension), and improves the separation effect and recovery rate of magnetic particles or magnetic separation liquid (components other than magnetic particles in magnetic suspension).
