Description

Technical Field

[0001] The invention relates to the technical field of free amine monitoring, in particular to a free amine monitoring analyzer. Background Art

[0002] Free amines are a class of organic compounds commonly found in food, usually formed by amino acids, amino acid degradation products and microbial metabolites. Common free amines include histamine, tyrosine, spermine and phenylethylamine. These compounds may be produced during product processing, storage or fermentation. High concentrations of free amines can have adverse effects on human health, so it is necessary to timely detect the content of free amines through monitoring analyzers and other equipment;

[0003] During the factory production process, when the liquid flowing in the pipeline is transported, it is in a crystalline state that is insoluble in water and has a sticky property. After a long period of transportation, it will adhere to the inner wall of the pipeline, causing the aperture of the inner wall of the pipeline for liquid circulation to become smaller and smaller, which directly affects its transportation efficiency. In addition, most of the factories use multi-section pipelines for splicing. However, if the inner wall of the pipeline located at the installation site of the monitoring analyzer is affected by adhesion, it is necessary to dismantle the adjacent pipelines for processing, which is troublesome, time-consuming and labor-intensive.

[0004] The plug-in meter in the monitoring analyzer is connected to the factory pipeline through the base and the connecting pipe. However, since the bottom of the connecting pipe is in contact with the solution in the factory pipeline for a long time, free amines are easily attached to its outer wall. Over time, crystal adhesion will also form, affecting the flow rate of the solution in the pipeline here. In addition, when the monitoring analyzer is monitoring the solution, the solution is transported from the connecting pipe. If more free amines are attached here, it will also affect the free amine concentration in the test solution, resulting in errors in the actual results of the instrument analysis.

[0005] Therefore, a free amine monitoring analyzer is proposed. Summary of the invention

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. By monitoring the concentration of free amine in the solution in the plant pipeline, the pH value of free amine is determined. When the solution in the detection tube and the branch pipe flows, the initial power is provided for the rotation of the spray pipe, so that the neutralization solution in the neutralization solution proportioning box can be evenly sprayed in a rotating manner. The inner wall environment around the liquid inlet of the connecting pipe near the inner wall of the detection tube is treated to prevent the sticky crystals of free amine from adhering to the inner wall of the detection tube near the liquid inlet of the connecting pipe, ensuring that the flow aperture of the inner wall of the detection pipeline is not affected, and ensuring the stability of the circulation and transportation of the free amine solution;

[0021] 2. By treating the inner wall environment around the liquid inlet of the connecting tube near the inner wall of the detection tube, the sticky crystals of free amines are prevented from adhering to the inner wall of the detection tube near the connecting tube near the liquid inlet, thereby optimizing the convenience of maintaining the inner wall of the detection pipe. With the change of the water flow, the spraying height can be adjusted by the cooperation of the airbag, so that the inside of the detection pipe can be maintained more comprehensively without disassembling multiple sections of the pipe, which saves time and effort.

[0022] 3. By following the flow of the solution, the propeller blades are driven to rotate, which in turn can provide a power source for the rotation of the screw rod. The screw rod is driven to rotate with the cooperation of the bevel gear set, and then the ring brush can move up and down on a section of the outer wall of the connecting tube located in the detection tube through the limit cooperation of the vertical rod, so as to process the free amine crystals adhering to the outer wall, so as to avoid the solution entering from the bottom of the connecting tube for monitoring due to the influence of the attached crystals, which may affect the accuracy of the monitoring results;

[0023] 4. The annular brush can move up and down on a section of the outer wall of the connecting tube located in the detection tube to process the free amine crystals adhering to the outer wall, thereby ensuring smooth flow of the solution in the detection tube. The continuous attachment of free amines to the outer wall of the connecting tube will not affect the flow rate of the solution here, thereby ensuring the real-time and more stable monitoring of the free amine content in the solution.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] See also Figures 1 to 12 , is an embodiment provided by the present invention: a free amine monitoring analyzer, comprising a mounting base 1, a plug-in meter head 2 is fixedly connected to the top of the mounting base 1, a connecting tube 3 is fixedly connected to the bottom of the mounting base 1, a detection tube 8 is fixedly connected to the mounting base 1 through the connecting tube 3, a convenient maintenance component for neutralizing free amine crystals attached to the inner wall of the detection tube 8 is arranged inside the detection tube 8, and a treatment anti-attachment component for treating the outer wall of the bottom end of the connecting tube 3 is arranged inside the detection tube 8 at the bottom of the connecting tube 3;

[0046] The anti-attachment treatment component includes two inverted T-shaped seats 71 , and the top ends of the inverted T-shaped seats 71 on both sides are fixedly connected to the bottom of the connecting pipe 3 .

[0047] Wherein: the plug-in meter head 2 is connected to the connecting tube 3 through the mounting seat 1, and the connecting tube 3 is installed on the top of the detection tube 8. The monitoring of free amines is detected by the plug-in meter head 2 and the sensor. The solution enters from the bottom end port of the connecting tube 3 and enters the internal cavity of the plug-in meter head 2 through the mounting seat 1 to monitor and analyze the whole process. The material of the solution proportioning box 61 is selected from high-density polyethylene, which has good corrosion resistance and sealing, can prevent leakage and contamination of the neutralization solution, is light and easy to clean, and is easy to use;

[0048] More preferably: the plug-in meter head 2, the mounting seat 1 and the connecting pipe 3 are connected and installed in sequence. In view of the different acidity and alkalinity of the free amine substance in different solution environments, the pH value thereof is first measured by the plug-in meter head 2, and a solution for neutralization thereof is injected into the solution proportioning box 61 according to the acidity and alkalinity thereof;

[0049] The convenient maintenance component also includes two telescopic hoses 62, the outer walls of the telescopic hoses 62 on both sides of the farthest end are penetrated and fixedly connected to the inside of the detection tube 8, the outer walls of the telescopic hoses 62 on both sides are fixedly connected to the inside of the neutralization solution proportioning box 61, and the outer walls of the telescopic hoses 62 on both sides are fixedly connected with a neutralization liquid one-way valve 63, the left and right sides of the inner wall of the detection tube 8 are fixedly connected with vertical poles 64, and the outer walls of the vertical poles 64 on both sides are slidably connected with air bags 66, and the side of the air bags 66 on both sides close to the connecting tube 3 is fixedly connected with a square collecting tube 65, and the inner walls of the square collecting tubes 65 on both sides are respectively slidably connected to the outer walls of the vertical poles 64 on both sides, and the middle part of the side close to the square collecting tubes 65 on both sides is rotatably connected with a conveying tube 67, transmission spiral blades 68 are fixedly connected to the outer walls of the delivery pipes 67 on both sides, butterfly valves 69 are fixedly connected to the outer walls of the ends of the delivery pipes 67 on both sides away from the square collecting pipe 65, driving spiral blades 610 are fixedly connected to the bottom of the butterfly plates in the butterfly valves 69 on both sides, spray pipes 611 are fixedly connected to the ends of the delivery pipes 67 on both sides away from the square collecting pipe 65, and a plurality of nozzles 612 are fixedly connected to the tops of the spray pipes 611 on both sides, a measuring tube 613 is fixedly connected to the inside of the plug-in meter head 2, a mixed liquid one-way valve 614 is fixedly connected to the outer wall of the end of the measuring tube 613 away from the plug-in meter head 2, and the end of the measuring tube 613 away from the plug-in meter head 2 passes through and is fixedly connected to the inside of the detection tube 8;

[0050] Wherein: the flow direction of the neutralizing liquid one-way valve 63 is from the neutralizing liquid proportioning box 61 to the square collecting pipe 65, and the flow direction of the mixed liquid one-way valve 614 is from the bottom end of the measuring tube 613 to the top end thereof and transported to the cavity inside the plug-in meter head 2;

[0051] Better: when the solution starts to be transported into the pipeline, as the solution in the pipeline is transported and flows, the liquid level gradually rises according to the total amount of solution transported, thereby driving the airbag 66 to move upward. First, the acidity and alkalinity of the free amine in the solution are determined by the analyzer and the corresponding neutralizing solution is configured. Then, the neutralizing solution one-way valves 63 on both sides are opened by button 5, so that the neutralizing solution can be transported to the inside of the square collection pipe 65 along the telescopic hose 62. The square collection pipe 65 and the airbag 66 are fixedly connected so that they can move together. While the solution is flowing and transported, the transmission spiral blade 68 and the driving spiral blade 610 can rotate, and then the transmission spiral blade 68 can drive the delivery pipe 67 and the spray pipe 611 to rotate together. While the driving spiral blade 610 rotates, the circular butterfly plate in the butterfly valve 69 can be driven to rotate, so that the butterfly valve 69 can be opened, so that the neutralizing solution in the square collection pipe 65 flows from the delivery pipe 67 to The inside of the spray pipe 611 is finally sprayed out by each nozzle 612. The spray pipe 611 moves with the air bag 66 through the square collecting pipe 65 and rotates to spray the inner wall of the pipe. Correspondingly, when the solution transportation in the pipe is completed, the liquid level of the solution will gradually decrease. The air bag 66 drives the square collecting pipe 65 and the spray pipe 611 to move downward to spray the neutralizing liquid on the lower inner wall of the pipe, so that the inside of the pipe can be more comprehensively neutralized and maintained regularly. The neutralizing liquid uses sodium bicarbonate to neutralize the free amines accumulated in the pipe, thereby reducing the risk of corrosion and ensuring that the liquid flowing in the pipe is non-polluting. Finally, after the treatment operation is completed, the mixed liquid one-way valve 614 is opened, so that the liquid that is sprayed and dropped and merged with the original solution is transported by the measuring tube 613 to the inside of the plug-in meter head 2 for measurement to determine whether the neutralization maintenance treatment of the inner wall environment of the pipe is stable;

[0052] The anti-attachment processing component also includes a propeller 72, which is rotatably connected to the middle part of the right inverted T-shaped seat 71, and the middle part of the propeller 72 is fixedly connected to an active bevel gear 73, which is rotatably connected to the middle part of the right inverted T-shaped seat 71, and the top of the right inverted T-shaped seat 71 is rotatably connected to a driven bevel gear 74, and the top of the driven bevel gear 74 is fixedly connected to a reciprocating screw rod 75, and the bottom of the driven bevel gear 74 is meshed and connected to the top of the active bevel gear 73, and the reciprocating screw rod One end of 75 away from the driven bevel gear 74 is rotatably connected to the right side of the bottom of the connecting tube 3, the top of the left inverted T-shaped seat 71 is fixedly connected with a vertical rod 76, and one end of the vertical rod 76 away from the left inverted T-shaped seat 71 is fixedly connected to the left side of the bottom of the connecting tube 3, and an annular brush 77 is threadedly connected to the outer wall of the reciprocating screw rod 75, and the inner wall of the annular brush 77 away from the reciprocating screw rod 75 is slidably connected to the outer wall of the annular brush 77, and the inner wall of the annular brush 77 is slidably connected to the outer wall of the connecting tube 3;

[0053] Wherein: the inverted T-shaped seats 71 on both sides, the propeller 72, the driving bevel gear 73, the driven bevel gear 74, the reciprocating screw 75, the vertical rod 76 and the outer ring of the annular brush 77 are all made of stainless steel to ensure that the inner wall of the pipe is not affected when it contacts with the solution and can operate normally for treatment;

[0054] Preferably: the propeller 72 rotates with the flow of the solution liquid, and can drive the active bevel gear 73 to rotate together, and the driven bevel gear 74 meshing with it then rotates along, so that the reciprocating screw 75 fixedly connected to the top thereof rotates, and under the limit cooperation of the vertical rod 76, drives the annular brush 77 to move up and down on the outer wall of the connecting tube 3 located inside the detection tube 8, and treats the free amine crystals attached to the outer wall, so as to prevent the concentration of the free amine inside the connecting tube 3 from being affected by the accumulated free amine crystals after the solution flows in from the bottom end of the connecting tube 3 during monitoring, resulting in the data accuracy of the monitoring and judgment being affected and causing misjudgment, and after the crystals on the outer wall of the bottom end of the connecting tube 3 are treated, the aperture size of the solution flow in this range will not be affected, so as to ensure the normal flow rate of the solution;

[0055] The front and rear sides of the plug-in meter head 2 are fixedly connected with a display screen 4, the front and rear sides of the plug-in meter head 2 are fixedly connected with a plurality of buttons 5 beside the display screen 4, and the left and right sides of the detection tube 8 are fixedly connected with branch pipes 9 through flanges;

[0056] Wherein: the detection tube 8 is connected to the connection tube 3, and the monitoring point of the free amine is located in the inner range thereof. In order to ensure its durability during use, the inner wall thereof is thickened;

[0057] Better: the data of the internal solution of the detection tube monitored by the plug-in meter 2 can be displayed through the display screen 4, the operation and use of each structure can be flexibly adjusted through each button 5, and the connection between the branch pipe 9 and the detection tube 8 is coordinated with the flow of the solution;

[0058] The above implementation works as follows:

[0059] The initialization steps are as follows:

[0060] First, the plug-in meter head 2 is connected to the connecting tube 3 through the mounting base 1 and installed on the top of the detection tube 8, and the pH value of the solution is tested. According to the pH value, a neutralizing solution is injected into the solution proportioning box 61.

[0061] The working steps are as follows:

[0062] like Figure 2 - Figure 3 and Figure 8As shown, when the solution begins to be injected into the pipeline, the analyzer first determines the acidity and alkalinity of the free amine in the solution and prepares the corresponding neutralizing solution, and then opens the neutralizing solution one-way valves 63 on both sides, so that the neutralizing solution can be transported to the inside of the square collection pipe 65 along the telescopic hose 62. As the solution in the pipeline is transported and flows, the liquid level gradually rises according to the total amount of the solution, and then the airbag 66 can be driven to move upward. The square collection pipe 65 and the airbag 66 are fixedly connected so that they can move together. While the solution is flowing and transported, the transmission spiral blade 68 and the driving spiral blade 610 can be rotated, and then the transmission spiral blade 68 can drive the delivery pipe 67 and the spray pipe 611 to rotate together;

[0063] like Figure 1 - Figure 3 , Figure 5 - Figure 8 As shown, the spiral blade 610 is driven to rotate and the circular butterfly plate in the butterfly valve 69 is driven to rotate, so that the butterfly valve 69 can be opened, so that the neutralizing liquid in the square collecting pipe 65 flows from the delivery pipe 67 to the inside of the spraying pipe 611, and is finally sprayed out by each nozzle 612. The spraying pipe 611 moves up and down with the air bag 66 through the square collecting pipe 65, and rotates to spray the inner wall of the pipe. Correspondingly, when the delivery of the solution in the pipe is completed, the liquid level of the solution will gradually decrease, and the air bag 66 drives the square collecting pipe 65 and the spraying pipe 611 to move downward, and the neutralizing liquid is sprayed on the lower inner wall of the pipe, so that the neutralizing liquid can be more comprehensively sprayed. Regular neutralization maintenance is performed inside the pipeline to neutralize the free amines accumulated in the pipeline, thereby reducing the risk of pipeline corrosion. Some pipeline materials are particularly sensitive to acid-base environments and are more susceptible to corrosion. Regular acid-base neutralization care may be more necessary for these materials to ensure long-term stable operation of the pipeline. During the flow and transportation of the solution in the pipeline, the mixed liquid one-way valve 614 is opened by controlling the button 5, so that the liquid that is sprayed and mixed with the original solution is transported by the measuring tube 613 under the pressure of the continuous output of the liquid, and gradually flows to the inside of the plug-in head 2 for measurement to determine whether the neutralization maintenance treatment for the pipeline inner wall environment is stable;

[0064] like Fig. 9 - Fig.12As shown, the propeller 72 rotates with the flow of the solution liquid, and can drive the active bevel gear 73 to rotate together, and the driven bevel gear 74 meshing with it then rotates along, so that the reciprocating screw 75 fixedly connected at the top thereof rotates, and drives the annular brush 77 to move up and down on the outer wall of the connecting tube 3 located in a section inside the detection tube 8 under the limit cooperation of the vertical rod 76. During the monitoring process of the solution, the solution is input from the bottom end of the connecting tube 3, and the solution will definitely contact the bottom end of the connecting tube 3 when it flows. If the crystals are not processed, they will merge with the crystals during the flow of the solution, which will affect the concentration of free amines contained in the solution itself. The free amine crystals attached to the outer wall are processed to prevent the concentration of free amines inside the solution from being affected by the accumulated free amine crystals after the solution flows in from the bottom end of the connecting tube 3 during monitoring, resulting in the data accuracy of the monitoring and judgment being affected and causing misjudgment. After the crystals on the outer wall of the bottom end of the connecting tube 3 are processed, the aperture size of the solution flow within this range will not be affected, thereby ensuring the normal flow rate of the solution.
