Description

Technical Field

[0001] The present invention relates to the technical field of anti-deterioration packaging containers, in particular to an anti-deterioration chemical raw material storage tank. Background Art

[0002] Storage tanks are widely used in the food, pharmaceutical, and chemical industries as core equipment for storing various liquid media (especially perishable liquids such as juice, dairy products, liquid medicines, and specific chemicals). However, these tanks generally face a key challenge during long-term storage and use: the risk of spoilage of the contents.

[0003] This risk is particularly prominent in scenarios where the tank needs to be opened frequently for sampling, adding materials or additives. Each time the tank is opened, the external environment (such as air, microorganisms, dust and other pollutants) will inevitably invade the space inside the tank. The introduction of air will accelerate the oxidation reaction of the liquid, and the entry of microorganisms may cause rapid reproduction. The dual effects significantly aggravate the spoilage process of the contents.

[0004] To monitor the state of the liquid in the tank, confirm whether it has deteriorated, and extend its shelf life, operators often need to conduct regular sampling tests and sometimes add chemical preservatives, fungicides, and other substances. However, these necessary maintenance operations themselves pose a new round of exposure risks when the tank is opened.

[0005] Based on the above reasons, we hope to design a storage tank with integrated sealing protection and anti-corrosion functions to solve the deterioration problem caused by the above reasons. Summary of the Invention

[0006] The purpose of the present invention is to solve the problems raised in the background technology and to propose a chemical raw material storage tank that prevents deterioration.

[0010] The liquid guiding assembly includes a vertical telescopic rod, a driving unit and a transverse telescopic rod. The vertical telescopic rod is used to adjust the position of the transverse telescopic rod, and the driving unit is used to drive the transverse telescopic rod to rotate, thereby stirring the liquid in the sampling tube.

[0011] As a further solution of the present invention: the sealing assembly includes a base and an annular sealing ring, the annular sealing ring is sleeved on the sampling tube, the inner surface of the annular sealing ring is in contact with the sampling tube, and the outer surface is in contact with the base, and multiple transmission units are installed in the base to drive the annular sealing ring to roll along the sampling tube.

[0012] As a further solution of the present invention: the base is fixedly mounted on the upper surface of the isolation plate, and the base is sleeved on the outer side of the annular sealing ring. The base is provided with a plurality of mounting grooves on a side facing the annular sealing ring. The plurality of mounting grooves are arranged radially, and a transmission unit is correspondingly mounted in each mounting groove.

[0013] The transmission unit is composed of a transmission belt and a transmission gear set. The transmission belt is tightened on the transmission gear set and driven by the transmission gear set to rotate. The transmission belt is in contact with the annular sealing ring, and the contact point between the two is attracted by a soft magnetic strip.

[0014] As a further solution of the present invention: the transmission belt is square in overall direction and performs rotational motion. The side of the transmission belt facing the annular sealing ring is vertically oriented, parallel to the axis of the sampling tube, and flush with the base surface.

[0015] As a further solution of the present invention: the size of the installation groove is set according to the shape of the transmission belt, and the transmission belt is embedded in the installation groove.

[0016] As a further solution of the present invention: the isolation plate is made of biodegradable polyester material, the upper surface of which is configured as a honeycomb-shaped cavity filled with antioxidant particles;

[0017] The annular sealing ring is an annular airbag made of elastic silicone;

[0018] The sampling tube is made of polyvinylidene fluoride material.

[0019] As a further solution of the present invention: the top of the vertical telescopic rod is fixed to the lower surface of the isolation plate, and the driving unit is composed of a fixing member, a driving wheel and a driven wheel. The fixing member is fixedly installed at the bottom of the vertical telescopic rod. The fixing member is a rectangular frame structure, and the driving wheel is rotatably installed inside. The driving wheel is driven by a motor to rotate, and the upper surface of the driving wheel is provided with a circle of meshing teeth.

[0020] Limiting ears are provided on both sides of the fixing piece, and a transverse telescopic rod is installed on each limiting ear seat. The two transverse telescopic rods are symmetrically installed, horizontally passing through the limiting ears at their corresponding positions, and at the same time one end is inserted into the fixing piece and fixedly connected to the driven wheel at the corresponding position of the meshing tooth groove, and the other end is provided with a stirring blade, and the driven wheel is meshed with the meshing tooth groove.

[0021] As a further solution of the present invention: the stirring blades on the two transverse telescopic rods, one facing the through hole on the sampling tube, and the other facing away from the through hole;

[0022] The stirring blade is a spiral stirring blade.

[0023] As a further solution of the present invention: a plurality of guide wheels are installed on the upper surface of the base, and the guide wheels are distributed in a circular array and fit the surface of the sampling tube;

[0024] The position of one of the guide wheels corresponds to the position of the through hole, and a pressure sensor is provided on the guide wheel.

[0025] Compared with the existing technology, the advantages of the present invention are:

[0026] 1. By setting up an isolation plate, the liquid stored inside is sealed under the isolation plate, effectively isolating the liquid from the outside air to prevent oxidation and impurities from mixing. The upper surface of the isolation plate is provided with a honeycomb-shaped chamber and filled with antioxidant particles, which can continuously absorb oxygen in the storage tank, slow down the oxidation reaction rate of the raw materials, effectively extend the shelf life of the raw materials, and further enhance the anti-deterioration ability of the storage tank.

[0027] 2. Equipped with a dedicated sampling tube for sampling and adding additives, there is no need to open the lid frequently, preventing the internal liquid from deteriorating at the root. In addition, each through-hole of the sampling tube is equipped with an automatic opening and closing device, which can accurately control the opening and closing of the through-hole according to actual operational needs. When sampling, adding preservatives and other operations, the corresponding through-hole is opened as needed to minimize the possibility of external contaminants entering the storage tank. Compared with the traditional frequent opening of the tank, the risk of internal raw material deterioration is greatly reduced.

[0028] 3. The sealing assembly adopts an annular sealing ring design. During the lifting process of the isolation plate, it will roll up and down along the sampling tube under the drive of the transmission unit, replacing the friction sliding mode of traditional seals with a rolling mode. It effectively avoids the excessive wear of traditional seals due to long-term use, which leads to a decrease in sealing effect, and the problem of wear debris falling into the internal liquid and causing raw material contamination.

[0029] 4. A liquid guide assembly is set under the isolation plate, in which the horizontal telescopic rod can accurately penetrate into the through hole of the sampling tube to perform telescopic stirring operations. This can not only promote the full interaction and flow of the liquid in the sampling tube and the liquid in the storage tank, effectively avoid liquid stratification or precipitation due to long-term standing of the original liquid, but also accelerate the diffusion of additives.

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0046] Reference Figure 1-14 A chemical raw material storage tank for preventing deterioration includes a storage tank 1. A top cover 11 is provided on the top of the storage tank 1, and an isolation plate 2 and a sampling tube 12 vertically penetrating the isolation plate 2 are provided inside. The top cover 11 is connected to the storage tank 1 by bolts, and a sealing strip is provided at the connection to achieve a sealed connection. The density of the isolation plate 2 is less than the density of the liquid in the storage tank 1. The isolation plate 2 floats on the surface of the liquid. As the liquid rises and falls, the isolation plate 2 isolates and protects the internal liquid, effectively preventing external air and impurities from entering the storage tank, while preventing the upper liquid from contacting the air, thereby preventing oxidation and deterioration.

[0047] The isolation plate 2 is made of biodegradable polyester material, and a honeycomb-shaped chamber is provided on the upper surface, which is filled with antioxidant particles. It can continuously absorb oxygen entering the storage tank, slow down the oxidation reaction rate of the raw materials, and effectively extend the shelf life of the raw materials (a protective layer or covering film is provided on the upper surface of the honeycomb-shaped chamber, and the protective layer is embedded in the upper surface of the isolation plate 2, and can be manually opened to replace the antioxidant particles).

[0048] The sampling port 111 and the exhaust valve are opened on the top cover 11, and the sampling port 111 is connected to the sampling tube 12 by plugging. The sampling tube 12 can be detachably installed in the storage tank 1. In actual use, the operator can use the sampling tube 12 through the sampling port 111 to take samples and add preservatives and fungicides. There is no need to frequently open the entire top cover 11, thereby avoiding the contamination of the liquid in the storage tank 1 by the external environment and preventing the internal liquid from deteriorating at the source. The sampling tube 12 is made of polyvinylidene fluoride (PVDF) material. PVDF has excellent chemical stability and resistance to corrosion by chemical substances, ensuring that it will not react with the raw materials and affect the quality of the raw materials during the sampling and additive addition process. In addition, PVDF material is a recyclable material and can be recycled and reprocessed when the sampling tube 12 is damaged or replaced.

[0049] On the sampling tube 12, a plurality of through holes 121 are evenly distributed along the axial direction, and each through hole is installed with an automatic opening and closing component, which can be precisely opened and closed by electromagnetic control or mechanical control (the automatic opening and closing component can adopt an electromagnetic valve or a mechanical switch structure such as a mechanical iris structure). As the isolation plate 2 rises and falls, the through hole 121 located above the isolation plate 2 closes the automatic opening and closing component, and the through hole 121 located below the isolation plate 2 remains in an open state. Closing the through hole 121 above the isolation plate 2 can prevent air from passing through the sampling tube 12 and affecting the quality of the liquid, thereby minimizing the risk of internal raw material deterioration.

[0050] Reference Figure 6-10 A sealing assembly 3 is provided on the upper surface of the isolation plate 2 at the position where the sampling tube 12 passes through, and a liquid guide assembly 4 is provided on the lower surface at the position where the sampling tube 12 passes through; the sealing assembly 3 includes a base 31 and an annular sealing ring 32, the annular sealing ring 32 is sleeved on the sampling tube 12, the inner surface is in contact with the sampling tube 12, and the outer surface is in contact with the base 31, the base 31 is fixedly installed on the upper surface of the isolation plate 2, and the base 31 is sleeved on the outside of the annular sealing ring 32, the base 31 faces one side of the annular sealing ring 32, and a plurality of mounting grooves 311 are evenly arranged in a radial pattern, and a transmission unit 33 is installed in each mounting groove 311; the annular sealing ring 32 is sleeved on the sampling tube 12, and is an annular airbag structure made of elastic silicone, the inner surface of which is tightly fitted with the sampling tube 12, and the outer surface is in contact with the base 31.

[0051] The transmission unit 33 is composed of a transmission belt 331 and a transmission gear set 332. The transmission belt 331 is tightened on the transmission gear set 332 and is driven by the transmission gear set 332 to perform rotational motion. The transmission gear set 332 is driven by a micro motor.

[0052] The transmission belt 331 is fitted with the annular sealing ring 32, and a soft magnetic strip is set at the joint between the two. The magnetic attraction of the soft magnetic strip is utilized. Specifically, a strip magnetic strip is attached to the surface of the transmission belt 331, and the annular sealing ring 32 is also provided with a strip magnetic strip at the joint position with the transmission belt 331, so as to ensure that the transmission belt 331 can effectively drive the annular sealing ring 32 to roll along the sampling tube 12 during the movement. Figure 14 As shown in the figure, this rolling mode replaces the friction sliding mode of traditional seals, effectively avoiding the problems of excessive wear of traditional seals due to long-term use, which leads to reduced sealing effect and wear debris falling into the internal liquid to cause raw material contamination, thereby improving the reliability of the sealing component and the anti-pollution ability of the tank.

[0053] The transmission belt 331 is oriented in a square shape as a whole for rotational motion. The side facing the annular sealing ring 32 is vertically oriented, parallel to the axis of the sampling tube 12, and flush with the surface of the base 31. This design allows the annular sealing ring 32 to fit the transmission belt 331 while also fitting with the base 31. The size of the mounting groove 311 is set according to the shape of the transmission belt 331, so that the transmission belt 331 is embedded in the mounting groove 311 to avoid deviation during operation and ensure that it is always tightly attracted to the annular sealing ring 32 when it drives the annular sealing ring 32 to roll, performing continuous motion.

[0054] A plurality of guide wheels 312 are installed on the upper surface of the base 31. These guide wheels 312 are distributed in a circular array and fit against the surface of the sampling tube 12. The position of one of the guide wheels 312 corresponds to the position of the through hole 121, and a pressure sensor is installed on the guide wheel 312. The guide wheel 312 plays an auxiliary supporting and guiding role. The pressure sensor can monitor the pressure changes near the through hole 121 in real time and provide data support for system control. Specifically, when the guide wheel 312 rolls over the sampling tube 12, the pressure sensor can monitor the position of the through hole 121 it rolls over. In addition, the position of the liquid level and the isolation plate 2 can be determined by setting a liquid level sensor in the storage tank 1 or setting a liquid level sensor under the isolation plate 2.

[0055] Reference Figure 11-12 The liquid guiding assembly 4 includes a vertical telescopic rod 41, a driving unit 42 and a transverse telescopic rod 43. The vertical telescopic rod 41 and the transverse telescopic rod 43 are both automatic telescopic rods that can realize telescopic movements. The vertical telescopic rod 41 is used to adjust the position of the transverse telescopic rod 43, and the driving unit 42 is used to drive the transverse telescopic rod 43 to rotate.

[0056] The driving unit 42 consists of a fixing part 421, a driving wheel 422 and a driven wheel 423. The top of the vertical telescopic rod 41 is firmly fixed to the lower surface of the isolation plate 2, and a fixing part 421 is installed at the bottom of the vertical telescopic rod 41. The fixing part 421 is a rectangular frame structure, and a driving wheel 422 is rotatably installed inside it. The driving wheel 422 is driven by a motor to rotate (the motor is embedded in the fixing part 421), and the motor is connected to the center of the driving wheel 422 to drive the driving wheel 422 to rotate. A circle of meshing teeth 4221 is provided on the upper surface of the driving wheel 422, and limiting ear seats 4211 are symmetrically provided on both sides of the fixing part 421. A transverse telescopic rod 43 is installed on each limiting ear seat 4211. The two transverse telescopic rods 43 are installed symmetrically, and the limiting ear seats 4211 at their corresponding positions are horizontally penetrated. One end penetrates into the fixing part 421 and is fixedly connected to the driven wheel 423 at the corresponding position of the meshing teeth 4221. A stirring blade 431 is installed at the other end.

[0057] The driven wheel 423 is engaged with the meshing tooth groove 4221 on the driving wheel 422. When the driving wheel 422 rotates under the drive of the motor, the meshing tooth groove 4221 drives the driven wheel 423 to rotate. Since the transverse telescopic rod 43 is limited by the limiting ear seat 4211 and the fixing member 421, the transverse telescopic rod 43 can only rotate on its own.

[0058] The stirring blades 431 on the two transverse telescopic rods 43, one faces the through hole 121 on the sampling tube 12, and the other faces away from the through hole 121, and the stirring blades 431 are spiral stirring blades. This design can stir the liquid in the storage tank 1 and the sampling tube 12 when the transverse telescopic rod 43 rotates. In addition, the fixed end of the transverse telescopic rod 43 is stuck in the meshing tooth groove 4221 through the driven wheel 423, and the stirring blades 431 are installed at the telescopic end of the transverse telescopic rod 43, so that the transverse telescopic rod 43 can be extended and retracted while rotating and stirring.

[0059] When it is necessary to stir the liquid in the storage tank 1 and the sampling tube 12, the vertical telescopic rod 41 is extended, so that the horizontal telescopic rod 43 is inserted into the through hole 121 of the sampling tube 12, and the motor drives the driving wheel 422 to rotate. Through the meshing of the meshing tooth groove 4221 and the driven wheel 423, the horizontal telescopic rod 43 is driven to rotate, and the stirring blade 431 rotates accordingly. This not only promotes the full interaction and flow of the liquid in the sampling tube 12 and the liquid in the storage tank 1, and effectively avoids liquid stratification or precipitation of the raw materials due to long-term standing, but the stirring blades 431 arranged in opposite directions can also form a eddy current field to accelerate the diffusion of additives.

[0060] When it is necessary to measure and sample the liquid in the sampling tube 12, stirring can also be performed first to ensure that the quality of the liquid extracted from the sampling tube 12 is the same as the actual liquid in the storage tank 1. At the same time, the stable state of the surface tension of the liquid in the sampling tube is destroyed, and the capillary phenomenon caused by the adhesion of the tube wall is broken, thereby reducing the resulting liquid level difference and improving the accuracy of the measurement.

[0061] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are common means well known to those skilled in the art.

[0062] The working steps of this application are as follows:

[0063] S1: Liquid is injected into the storage tank 1 through the sampling tube 12. The automatic opening and closing members of all the through holes 121 on the sampling tube 12 are opened, and the exhaust valve is opened at the same time. As the liquid is injected, the isolation plate 2, which has a lower density than the liquid in the storage tank 1, gradually rises under the action of buoyancy. When the liquid level reaches a predetermined height or the isolation plate 2 approaches the top cover 11, the liquid injection is stopped.

[0064] S2: As the isolation plate 2 floats with changes in the liquid level, the transmission gear set 332 in the transmission unit 33 of the sealing assembly 3 continuously drives the transmission belt 331 to rotate, driving the annular sealing ring 32 to roll up and down along the sampling tube 12 to maintain good sealing performance. At the same time, the guide wheels 312 distributed in a circular array on the upper surface of the base 31 roll in contact with the surface of the sampling tube 12. The guide wheels 312, which are equipped with pressure sensors, monitor the position of the through-holes 121 they roll over in real time. The pressure sensors feed the data back to the control system, which, combined with the data from the preset liquid level sensor in the storage tank 1, accurately determines the specific position of the isolation plate 2 and the corresponding through-hole 121.

[0065] S3: The control system automatically controls the state of the automatic opening and closing member of the through hole 121 according to the real-time position of the isolation plate 2. The automatic opening and closing member of the through hole 121 located above the isolation plate 2 is closed to prevent the residual air above the isolation plate 2 from affecting the liquid quality through the sampling tube 12; the automatic opening and closing member of the through hole 121 located below the isolation plate 2 remains open to ensure the normal circulation of the liquid in the storage tank;

[0066] S4: When sampling or liquid level measurement is required through the sampling tube 12, the length of the vertical telescopic rod 41 is adjusted according to the position of the previous through hole 121 detected by the pressure sensor (i.e., the position of the through hole 121 closest to the isolation plate 2), and the transverse telescopic rod 43 is adjusted to a suitable position so that its stirring blade 431 can penetrate the through hole 121 of the sampling tube 12, driving the driving wheel 422 to rotate. The driving wheel 422 drives the driven wheel 423 to rotate through the meshing tooth groove 4221, causing the transverse telescopic rod 43 to rotate, and the stirring blade 431 to rotate accordingly. At the same time, the transverse telescopic rod 43 is extended and retracted. The rotation and extension of the stirring blade 431 promote full interaction and flow between the liquid in the sampling tube 12 and the liquid in the storage tank 1.

[0067] S5: After the stirring pretreatment is completed, sampling and testing or liquid level measurement operation is performed. After the operation is completed, the driving wheel 422 is stopped, the horizontal telescopic rod 43 is retracted to the initial position, and the vertical telescopic rod 41 is also restored to the initial state;

[0068] S6: If an additive needs to be added through the sampling tube 12, repeat step S4, so that the stirring blade 431 is inserted into the through hole 121 of the sampling tube 12 again and rotates and retracts to accelerate the diffusion of the additive in the liquid in the storage tank 1 and ensure uniform mixing;

[0069] S7: When it is necessary to empty or take out the raw materials in the storage tank 1, you can choose to extract them through the sampling tube 12, or you can directly open the top cover 11, take out the isolation plate 2 and pour out the internal liquid.

[0070] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
