Description

Technical Field

[0001] This utility model relates to the field of chemical reagent purification and processing technology, and in particular to a purification and processing component for chemical reagents. Background Technology

[0002] Chemical reagent purification and processing components refer to a class of specialized devices or modular systems used to remove impurities (such as particulate matter, organic / inorganic residues, moisture, etc.) from chemical reagents and improve their purity. Their core function is to purify industrial-grade or low-purity reagents to a high-purity level that meets specific experimental or production requirements through physical retention, adsorption separation, distillation and concentration techniques.

[0003] In the production and laboratory purification of chemical reagents, traditional equipment often faces problems such as low separation efficiency, complex operation and high maintenance costs. Although centrifugation can quickly separate suspended particles, high-speed rotation can easily lead to fluid turbulence and reduce separation accuracy. Adsorption purification relies on porous materials (such as activated carbon or molecular sieves), but existing devices are usually fixed structures. When changing adsorption materials, the machine needs to be shut down for disassembly, which affects continuous production. In addition, the fine filtration after solid-liquid separation often relies on independent membrane modules, which poses risks of equipment redundancy, increased energy consumption and reagent residue.

[0004] Existing integrated equipment has the following problems in fluid dynamics design: 1) The lack of flow guiding structure in the centrifuge chamber leads to unstable reagent flow path;

[0005] 2) The adsorption unit and centrifuge module are mostly fixed by welding or bolts, making disassembly and cleaning difficult;

[0006] 3) The symmetrical design of the precipitation collection chamber is prone to secondary precipitate resurfacing, which affects the purity of the purified reagent. Therefore, we propose a purification processing component for chemical reagents. Utility Model Content

[0007] In view of the problems existing in the prior art described above, this utility model is proposed.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0009] A purification and processing assembly for chemical reagents includes a centrifuge chamber, the inner wall of which is provided with guide vanes to optimize the reagent flow path, reduce turbulence, and improve centrifugation separation efficiency.

[0010] An adsorption tube is coaxially and detachably mounted on the centrifuge chamber. A porous ceramic substrate is installed on the inner wall of the adsorption tube to facilitate the replacement of adsorption materials, adapt to different reagent purification needs, and reduce maintenance costs.

[0011] A spiral guide is installed on the adsorption cylinder, and spiral blades are installed on the inner wall of the spiral guide to extend the reagent residence time and enhance the impurity adsorption effect.

[0012] The bottom liquid collection chamber is installed on the spiral guide member. The bottom liquid collection chamber includes a conical sedimentation hopper, an annular overflow groove, and a hydrophobic membrane to ensure the purity of the reagent.

[0013] As a technical solution for a purification and processing component for chemical reagents according to the present invention, the helix angle of the guide vane gradually decreases along the axial direction of the centrifuge chamber, so as to gradually reduce the fluid kinetic energy, avoid reagent splashing during centrifugation, and achieve a smooth transition separation.

[0014] As a technical solution of the purification and processing component for chemical reagents described in this utility model, the bottom of the centrifuge chamber is provided with a threaded groove, and the end of the adsorption tube away from the spiral guide has an integrally formed threaded edge corresponding to the threaded groove, and the threaded edge is adapted to the thread of the threaded groove. The adsorption tube is detachably installed on the centrifuge chamber through the threaded edge and the threaded groove coaxially, so as to facilitate the quick assembly and disassembly of the adsorption tube and the centrifuge chamber, simplify the cleaning process, and reduce the risk of cross-contamination.

[0015] As a technical solution for a purification and processing component for chemical reagents according to the present invention, the central axes of the conical precipitation hopper, the annular overflow trough, and the hydrophobic membrane are arranged eccentrically to prevent the precipitate from being agitated again due to fluid disturbance and to ensure the collection of high-purity reagents.

[0016] As a technical solution for a purification and processing component for chemical reagents described in this utility model, the purification and processing component is made entirely of quartz glass and PEEK composite material to balance corrosion resistance (adapting to strong acid / alkali reagents) and structural strength, thereby extending the component's lifespan.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] 1. This utility model optimizes the fluid dynamics path and improves centrifugal separation efficiency through the synergistic effect of the guide vanes and spiral vanes. At the same time, the eccentrically arranged conical sedimentation chamber and the hydrophobic membrane work together to effectively isolate impurities, avoid secondary pollution, and significantly improve reagent purity.

[0019] 2. This utility model, by adopting a detachable adsorption cylinder design, enables quick replacement of adsorption materials, adapting to purification needs in multiple scenarios. At the same time, the purification processing components are made of corrosion-resistant composite materials, which can reduce equipment wear and tear. Combined with the threaded connection design, the cleaning and maintenance process can be greatly simplified. Attached Figure Description

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Reference Figures 1-3 A purification and processing assembly for chemical reagents is provided. This purification and processing assembly for chemical reagents includes a centrifuge chamber 1. The inner wall of the centrifuge chamber 1 is provided with a flow guide plate 101, which can optimize the reagent flow path, reduce turbulence, and improve centrifugation separation efficiency.

[0028] Adsorption cylinder 2 is coaxially and detachably mounted on centrifuge chamber 1. A porous ceramic matrix 201 (such as activated alumina or molecular sieve) is installed on the inner wall of adsorption cylinder 2. The detachable adsorption cylinder 2 and porous ceramic matrix 201 can facilitate the replacement of adsorption materials, adapt to different reagent purification needs, and reduce maintenance costs.

[0029] The spiral guide 3 is installed on the adsorption cylinder 2. The spiral guide 3 has a spiral blade 301 installed on its inner wall. The spiral guide 3 and the spiral blade 301 can prolong the reagent residence time and enhance the impurity adsorption effect.

[0030] Bottom collection chamber 4 is installed on spiral guide 3. Bottom collection chamber 4 includes conical sedimentation hopper 401, annular overflow trough 402 and hydrophobic membrane 403. Conical sedimentation hopper 401 collects sediment, annular overflow trough 402 separates clear liquid, and hydrophobic membrane 403 prevents sediment from rising and ensures reagent purity.

[0031] Reference Figure 1 and Figure 3 The spiral angle of the guide vane 101 gradually decreases along the axial direction of the centrifuge chamber 1 (30° at the top and 10° at the bottom). In application, the decreasing spiral angle of the guide vane 101 can gradually reduce the fluid kinetic energy, avoid reagent splashing during centrifugation, and achieve a smooth transition separation.

[0032] Reference Figure 1 and Figure 2 The bottom of the centrifuge chamber 1 is provided with a threaded groove 102. The end of the adsorption cylinder 2 away from the spiral guide 3 has an integrally formed threaded edge 202 corresponding to the threaded groove 102. The threaded edge 202 is threaded and adapted to the threaded groove 102. The adsorption cylinder 2 is detachably installed on the centrifuge chamber 1 through the coaxial connection of the threaded edge 202 and the threaded groove 102. In application, the threaded groove 102 and the threaded edge 202 are threadedly engaged, which can realize the quick assembly and disassembly of the adsorption cylinder 2 and the centrifuge chamber 1, simplify the cleaning process, and reduce the risk of cross-contamination.

[0033] Reference Figure 1 and Figure 3 The conical sedimentation hopper 401, the annular overflow trough 402, and the hydrophobic membrane 403 are arranged eccentrically. In application, the eccentric arrangement of the conical sedimentation hopper 401, the annular overflow trough 402, and the hydrophobic membrane 403 can prevent the precipitate from being stirred up again due to fluid disturbance, and ensure the collection of high-purity reagents.

[0034] Reference Figures 1-3 The purification and processing components are made of quartz glass and PEEK (polyether ether ketone) composite material. In application, the quartz glass and PEEK composite material combines corrosion resistance (adapting to strong acid / alkali reagents) with structural strength, extending the life of the components.

[0035] The working principle of this utility model is as follows: By injecting the reagent to be purified from the top of the centrifuge chamber 1 and starting the centrifuge, the guide plate 101 guides the reagent to move smoothly down along the spiral channel. Large particles of impurities settle against the wall due to centrifugal force. Then the reagent flows into the adsorption cylinder 2. At this time, the porous ceramic matrix 201 adsorbs dissolved impurities, and the spiral guide plate 301 further extends the flow path and enhances the adsorption effect. At the same time, the reagent enters the conical sedimentation hopper 401. Trace suspended particles settle to the bottom of the hopper due to gravity. The clear liquid enters the annular overflow trough 402 due to the hydrophobic film 403. The hydrophobic film 403 prevents the precipitate from rising again. Finally, the high-purity reagent is discharged from the outlet.

[0036] This invention provides a purification and processing component for chemical reagents. Through the synergistic action of the guide plate 101 and the spiral plate 301, the fluid dynamics path can be optimized, and the centrifugal separation efficiency can be improved. The eccentrically arranged conical precipitation chamber 401 and the hydrophobic membrane 403 work together to effectively isolate impurities, avoid secondary pollution, and significantly improve reagent purity. At the same time, by adopting a detachable adsorption cylinder design, the adsorption material can be quickly replaced to adapt to the purification needs of multiple scenarios. The purification and processing component is made of corrosion-resistant composite material, which can reduce equipment wear and tear. Combined with the threaded connection design, the cleaning and maintenance process can be greatly simplified.
