Description

Technical Field

[0001] The invention relates to the field of equipment for producing magnesium sulfate injection, in particular to magnesium sulfate injection filtering equipment. Background Art

[0002] When producing the mother liquor of magnesium sulfate injection, in order to make the produced magnesium sulfate injection cleaner, the existing mother liquor of magnesium sulfate injection needs to be filtered. This filtration generally adopts ultrafiltration membrane filtration technology. The so-called ultrafiltration membrane filtration technology works by utilizing the micropores and microscopic channels of polymer materials to separate suspended matter, bacteria and other impurities in the liquid by physical interception, while retaining the substances that need to be retained. The ultrafiltration membrane filtration technology will not hinder the passage of magnesium sulfate and can filter out the bacteria in the solution, so it is very convenient and effective. However, there are still certain defects in the existing use of this technology to filter the mother liquor of magnesium sulfate injection. The main thing is that after a long time of use, the filter material of the ultrafiltration membrane filtration equipment will be affected to a certain extent, and the micropores will be blocked. It is possible that during the filtration, a part of the dissolved magnesium sulfate molecules will be filtered out, so the concentration of the filtered magnesium sulfate mother liquor is not up to standard. In view of this situation, the prior art generally does not set up a corresponding monitoring structure, nor does it set up corresponding control measures. Therefore, it is necessary to improve the prior art for this situation. Summary of the invention

[0003] The invention aims to provide a magnesium sulfate injection filtering device to solve the problem that the existing ultrafiltration membrane filtering device lacks a monitoring mechanism for whether the concentration of the filtered solution reaches the standard when in use.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: A magnesium sulfate injection filtration device comprises an internal pressure ultrafiltration membrane assembly, wherein a clean liquid storage tank is provided at the clean liquid discharge port of the internal pressure ultrafiltration membrane assembly, a liquid discharge sampling port with isolation and disinfection functions is provided on one side of the clean liquid storage tank, and a solute addition port is provided on the top of the clean liquid storage tank.

[0005] The mother liquor of magnesium sulfate injection is filtered by an internal pressure ultrafiltration membrane assembly. After filtration, the mother liquor of magnesium sulfate injection enters a clean liquid storage tank. A liquid discharge sampling port with an isolation and disinfection function is provided on one side of the clean liquid storage tank, so that sampling and monitoring can be performed after filtration. When it is found after sampling that the magnesium sulfate concentration does not meet the standard, the corresponding solute can be added to the clean liquid storage tank through the solute addition port so that its concentration can meet the corresponding requirements.

[0006] As a further preferred embodiment of the present invention, a sensor of a conductivity meter is further provided in the middle of the clean liquid channel of the internal pressure ultrafiltration membrane assembly, and the sensor of the conductivity meter is connected to the electrical signal of the conductivity meter.

[0007] The internal pressure ultrafiltration membrane assembly can work very normally, and whether the filtered liquid meets the standard can also be monitored by conductivity. When a significant change in conductivity is detected, it proves that there is a problem with the ultrafiltration membrane in the internal pressure ultrafiltration membrane assembly, and it can be repaired in time.

[0008] As a further preferred embodiment of the present invention, the liquid discharge sampling port with isolation and disinfection function includes a liquid discharge sampling tube, a sampling liquid discharge valve is provided at one end of the liquid discharge sampling tube close to the clean liquid storage tank, and a liquid outlet sealing isolation plug is provided at the liquid outlet end of the liquid discharge sampling tube. The portion of the liquid discharge sampling tube located between the sampling liquid discharge valve and the liquid outlet sealing isolation plug is a temporary placement section for the sampling liquid, and a heating and disinfection mechanism is provided in the middle of the temporary placement section for the sampling liquid.

[0009] When sampling, it is necessary to ensure the cleanliness of the liquid in the clean liquid storage tank. Therefore, the temporary placement section of the sampling liquid is first disinfected with a heating and disinfection mechanism, and then the sampling liquid discharge valve is opened to discharge the liquid. After discharge, the sampled liquid is located in the temporary placement section of the sampling liquid. At this time, the sampling liquid discharge valve is closed, and finally the sealing isolation plug at the liquid outlet is opened. In this way, a pollution-free sampling operation is completed, which is cleaner. Finally, the sealing isolation plug at the liquid outlet can be closed after sampling, and then the heating and disinfection mechanism can be used for heating and disinfection.

[0010] As a further preferred embodiment of the present invention, the heating and disinfection mechanism includes an electric heating mesh plate evenly arranged in the middle of the temporary placement section of the sampling liquid.

[0011] The evenly arranged electric heating mesh plates can quickly complete heating and disinfection.

[0012] As a further preferred embodiment of the present invention, the front end and the rear end of the temporary placement section for the sampling liquid are both provided with heat insulation rings, and the exterior of the temporary placement section for the sampling liquid is provided with a heat insulation layer.

[0013] The heat insulation ring can isolate the front-to-back transfer of heat, and the heat insulation layer can prevent external operators from getting burned due to accidentally touching the temporary placement section of the sampling liquid.

[0014] As a further preferred embodiment of the present invention, a liquid outlet is provided at the bottom of the clean liquid storage tank, the liquid outlet is connected to a liquid outlet pipe, and the middle portion of the liquid outlet pipe is a coil section.

[0015] Since solute needs to be added when the concentration is insufficient, and the solute dissolves slowly without stirring, a coil section is set in the middle of the liquid outlet pipe. This not only increases the stroke, but also creates a circular flow pattern in the coil section, so that the solute can be better dissolved.

[0016] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects: 1. The mother liquor of magnesium sulfate injection is filtered by an internal pressure ultrafiltration membrane assembly. After filtration, the mother liquor of magnesium sulfate injection enters a clean liquid storage tank. A liquid sampling port with an isolation and disinfection function is provided on one side of the clean liquid storage tank, so that sampling and monitoring can be performed after filtration. When it is found that the magnesium sulfate concentration does not meet the standard after sampling, the corresponding solute can be added to the clean liquid storage tank through the solute addition port so that its concentration can meet the corresponding requirements.

[0017] 2. The internal pressure ultrafiltration membrane assembly can work very normally. Whether the filtered liquid meets the standard can also be monitored by conductivity. When a significant change in conductivity is detected, it proves that there is a problem with the ultrafiltration membrane in the internal pressure ultrafiltration membrane assembly, and it can be repaired in time.

[0018] 3. When sampling, it is necessary to ensure the cleanliness of the liquid in the clean liquid storage tank. Therefore, first use the heating and disinfection mechanism to disinfect the temporary placement section of the sampling liquid, and then open the sampling liquid discharge valve to discharge the liquid. After discharging, the sampled liquid is located in the temporary placement section of the sampling liquid. At this time, close the sampling liquid discharge valve, and finally open the sealed isolation plug at the liquid outlet end. In this way, a pollution-free sampling operation is completed, which is cleaner. Finally, after sampling, the sealed isolation plug at the liquid outlet end can be closed and then a heating and disinfection can be performed using the heating and disinfection mechanism.

[0019] 4. The evenly arranged electric heating mesh plates can quickly complete heating and disinfection.

[0020] 5. The heat insulation ring can isolate the front and back transfer of heat, and the heat insulation layer can prevent external operators from getting burned due to accidentally touching the temporary placement section of the sampling liquid.

[0021] 6. Since solute needs to be added when the concentration is insufficient, and the solute dissolves slowly without stirring, a coil section is set in the middle of the liquid outlet pipe. This not only increases the stroke, but also creates a circular flow pattern at the coil section, so that the solute can be better dissolved. BRIEF DESCRIPTION OF THE DRAWINGS
