Description

Technical Field

[0001] This utility model relates to the field of storage equipment technology, and in particular to a high-performance liquid chromatography mobile phase waste liquid storage device. Background Technology

[0002] High-performance liquid chromatography (HPLC), as a highly efficient and sensitive analytical technique, is widely used for the qualitative and quantitative detection of organic compounds. Its core principle is to use a high-pressure delivery system to pump the mobile phase (such as methanol, acetonitrile, water, or their buffer systems) into the chromatographic column. Separation is achieved based on the difference in the partition coefficients of the analytes between the stationary and mobile phases, and the signal is acquired by a detector. Depending on the separation mechanism, HPLC is mainly divided into adsorption chromatography, partition chromatography, ion exchange chromatography, and gel permeation chromatography, all of which rely on precise control of the mobile phase to obtain stable analytical results.

[0003] Currently, most common waste liquid collection devices are simple storage tanks or bottles, lacking effective waste gas treatment mechanisms, which can easily lead to a decline in laboratory air quality. In addition, traditional waste liquid containers are mostly one-piece structures, which are inconvenient to clean, replace and transport, especially when conducting multiple sets of experiments or when the types of waste liquid vary greatly, lacking flexibility and scalability. Utility Model Content

[0004] The technical problem to be solved by this utility model is: in order to overcome the problem that traditional waste liquid containers in the prior art are mostly integrated structures, which are inconvenient to clean, replace and transport, especially when conducting multiple sets of experiments or when the types of waste liquid are very different, and lack flexibility and scalability, a high-performance liquid chromatography mobile phase waste liquid holding device is provided.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a high-performance liquid chromatography mobile phase waste liquid holding device, including a transfer seat, a holding mechanism and a purification mechanism. The holding mechanism and the purification mechanism are both inserted into the transfer seat and are snap-fitted together. The air output end of the holding mechanism and the air input end of the purification mechanism are connected. The holding mechanism and the purification mechanism are connected to the transfer seat by plugging and snap-fitting, which can be quickly disassembled and installed. It is convenient to clean, replace or repair a certain module separately, which improves the maintainability and service life of the equipment. The purification module can be flexibly selected according to the properties of the waste liquid and experimental needs. Multiple holding units can also be combined on one transfer seat to adapt to the experimental waste liquid treatment needs of different scales.

[0006] To address the issues of waste liquid containers easily shaking and tipping over, and gas leakage caused by improperly positioned exhaust gas outlets, a further method is included: a holding mechanism comprising a holding box with a holding cavity; a liquid inlet communicating with the holding cavity on the top surface of the holding box; an air outlet communicating with the holding cavity on the side of the holding box near the purification mechanism; a first insertion block protruding from the bottom surface of the holding box; a first insertion groove matching the first insertion block on the top surface of the transfer seat; and the first insertion block of the holding box being inserted into the first insertion groove.

[0007] To address the issues of inconvenient and inefficient use caused by the often external or non-integrated nature of exhaust gas purification structures, a further purification mechanism is proposed, comprising a purification chamber and purification components. The purification chamber has a gas inlet on its side near the containing chamber, which connects to an air outlet. A gas outlet is also located on the purification chamber. The purification components are housed within the purification chamber, with their inlet and outlet connected to the gas inlet and outlet respectively. These components are used to purify the air discharged from the containing chamber. The purification chamber also features a second insertion block, and a transfer seat has a second insertion slot that matches the second insertion block. The second insertion block is inserted into the second insertion slot.

[0008] To address the issue of incomplete and limited waste gas purification methods, a purification assembly is further included, comprising a purification housing, a first connecting pipe, and a second connecting pipe. The input end of the first connecting pipe is connected to a gas inlet, and the output end of the first connecting pipe is connected to the lower part of the purification housing. The output end of the second connecting pipe is connected to an air outlet, and the input end of the second connecting pipe is connected to the top of the purification housing. The first and second connecting pipes are used for air circulation. The lower part of the purification housing contains a purification liquid that covers the output end of the first connecting pipe, and the upper part of the purification housing contains activated carbon particles.

[0009] To address the issues of gas flow relying on natural diffusion, low purification efficiency, and poor exhaust, the purification component further includes an air pump. The air pump is arranged inside the purification housing and positioned above the activated carbon particles. The output end of the air pump is connected to a second connecting pipe.

[0010] To address the issue of loose connections between the storage and purification modules, which can lead to detachment or air leakage, the system further includes a locking groove on the purification chamber and a locking block protruding from the storage chamber to match the locking groove, with the locking block fitting into the locking groove.

[0011] The beneficial effects of this utility model are as follows: This utility model provides a high-performance liquid chromatography mobile phase waste liquid holding device. Both the holding mechanism and the purification mechanism are connected to the transfer seat by plug-in and snap-fit ​​methods, which can be quickly disassembled and installed. It is convenient to clean, replace or repair a certain module separately, which improves the maintainability and service life of the equipment. The purification module can be flexibly selected according to the properties of the waste liquid and experimental needs. Multiple holding units can also be combined on one transfer seat to adapt to the experimental waste liquid treatment needs of different scales. Attached Figure Description

Detailed Implementation

[0015] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0016] like Figure 1 This is a schematic diagram of the structure of this utility model, a high-performance liquid chromatography mobile phase waste liquid holding device, including a transfer seat 1, a holding mechanism 2, and a purification mechanism 3. The holding mechanism 2 and the purification mechanism 3 are both inserted into the transfer seat 1 and are snap-fitted together. The air output end of the holding mechanism 2 and the air input end of the purification mechanism 3 are connected. The holding mechanism 2 and the purification mechanism 3 are connected to the transfer seat 1 by plugging and snap-fitting, which can be quickly disassembled and installed. It is convenient to clean, replace or repair a single module, which improves the maintainability and service life of the equipment. The purification module can be flexibly selected according to the properties of the waste liquid and experimental needs. Multiple holding units can also be combined on one transfer seat 1 to adapt to the experimental waste liquid treatment needs of different scales.

[0017] like Figure 1As shown, the holding mechanism 2 includes a holding box 21 with a holding cavity 211. The top surface of the holding box 21 has a liquid inlet 212 communicating with the holding cavity 211. The side of the holding box 21 near the purification mechanism 3 has an air outlet 213 communicating with the holding cavity 211. The bottom surface of the holding box 21 has a protruding first insertion block 214. The top surface of the transfer seat 1 has a first insertion groove 11 that matches the first insertion block 214. The first insertion block 214 of the holding box 21 is inserted into the first insertion groove 11, and the stability is enhanced by the insertion structure.

[0018] like Figure 1 As shown, the purification mechanism 3 includes a purification chamber 31 and a purification component 32. A gas inlet 311 is provided on the side of the purification chamber 31 near the holding chamber 21. The gas inlet 311 is connected to the air outlet 213. A gas outlet 312 is provided on the purification chamber 31. The purification component 32 is arranged inside the purification chamber 31. The input end of the purification component 32 is connected to the gas inlet 311, and the output end of the purification component 32 is connected to the gas outlet 312. The purification component 32 is used to purify the air discharged from the holding chamber 21. The purification module 3 is directly connected to the holding mechanism 2 to realize on-site treatment of waste gas, improve purification efficiency, and avoid damage to the human body after leakage. like Figure 1 As shown, the purification box 31 has a second plug-in block 314, and the transfer seat has a second plug-in slot 12 that matches the second plug-in block 314. The second plug-in block 314 is inserted into the second plug-in slot 12.

[0019] like Figure 1 As shown, the purification component 32 includes a purification housing 321, a first connecting pipe 322, and a second connecting pipe 323. The input end of the first connecting pipe 322 is connected to the gas inlet 311, and the output end of the first connecting pipe 322 is connected to the lower part of the purification housing 321. The output end of the second connecting pipe 323 is connected to the air outlet 213, and the input end of the second connecting pipe 323 is connected to the top of the purification housing 321. The first connecting pipe 322 and the second connecting pipe 323 are used to supply air circulation. The lower part of the purification housing 321 is filled with a purification liquid 324 that covers the output end of the first connecting pipe 322, and the upper part of the purification housing 321 is filled with activated carbon particles 325. Through the dual treatment of the purification liquid 324 and the activated carbon 325, the purification effect of the exhaust gas is significantly improved. The purification liquid 324 can be one or more of water (partial absorption), a special absorbent, or a high-boiling-point oil.

[0020] Furthermore, the diameter of the gas inlet 311 is larger than that of the air outlet 213, and sealing rings are arranged around both the gas inlet 311 and the air outlet 213 to further enhance the sealing effect.

[0021] like Figure 1As shown, the purification component 32 also includes an air pump 326, which is arranged inside the purification housing 321 and located above the activated carbon particles. The output end of the air pump 326 is connected to the second connecting pipe 323. The air pump actively draws air to enhance gas flow, improve processing speed and system stability. Furthermore, the air pump 326 can create negative pressure inside the purification housing 321 to prevent gas leakage from the contact between the air outlet 213 and the gas inlet 311, thereby improving safety.

[0022] like Figure 2 As shown, the purification box 31 has a locking groove 313, and the holding box 21 has a protruding locking block 215 that matches the locking groove 313. The locking block 215 is fitted into the locking groove 313. The locking structure enhances the reliability of the connection between modules and ensures the air circuit sealing.

[0023] Working process: Waste liquid is injected into the holding chamber 211 of the holding tank 21 through the inlet 212; harmful gases volatilized from the waste liquid enter the gas inlet 311 of the purification mechanism 3 through the air outlet 213; the gas enters the lower part of the purification shell 321 through the first connecting pipe 322 and undergoes preliminary absorption treatment through the purification liquid 324; the gas continues to rise and passes through the activated carbon particle layer 325 to further adsorb residual organic matter; the air pump 326 is started, and the purified gas is discharged from the gas outlet 312 through the second connecting pipe 323; if transfer or replacement is required, the holding mechanism 2 and the purification mechanism 3 can be pulled out from the transfer seat 1 for separate treatment or maintenance.

[0024] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
