Description

Technical Field

[0001] This utility model relates to the technical field of chemical liquid transportation, specifically a pressurized auxiliary discharge device for high-viscosity liquids in IBC containers. Background Technology

[0002] IBCs (Integrated Bulk Containers), also known as medium-sized bulk containers, are widely used for the storage, handling, and feeding of chemical liquids such as resins, adhesives, coatings, and additives. Commonly found in drum-type IBCs, they typically include a plastic inner liner, an external frame, a top filling port, and a bottom drain valve. During use, the liquid inside the container is drained through the bottom drain valve by gravity. For low-viscosity liquids, gravity drainage usually meets the requirements; however, for materials such as acrylic resins, epoxy resins, polyurethane resins, and high-viscosity adhesives, due to the higher flow resistance, relying solely on gravity drainage can easily lead to slow drainage speeds, long emptying times, and excessive residue on the container walls and bottom, thus affecting the feeding efficiency and raw material utilization rate of the production line.

[0003] To improve the discharge efficiency of high-viscosity liquids from IBC containers, existing on-site methods typically employ external transfer pumps, suction pipes, heating to reduce viscosity, tilting discharge, dedicated conical-bottom containers, or other specialized unloading equipment. While these methods can improve discharge efficiency to some extent, they also have corresponding drawbacks: external transfer pumps and suction pipes require additional power equipment, cleaning residual material in the pipes is difficult, and high-viscosity materials can easily cause discontinuous suction or pipe blockage; heating to reduce viscosity is energy-intensive and may affect the physical properties of some heat-sensitive resins or adhesives; tilting discharge is physically demanding and poses a safety risk on-site; dedicated conical-bottom containers or specialized unloading equipment are expensive and difficult to directly adapt to the widely used ordinary IBC containers.

[0004] Some on-site attempts have involved introducing compressed air into the IBC container to assist in discharge, creating pressure above the liquid surface to force the high-viscosity liquid out through the bottom drain valve. However, ordinary IBC containers are not typically specialized pressure vessels. Directly drilling holes in the container body to install air inlets, or making fixed modifications to the container body, lid, or drain structure, would not only damage the original structure and versatility of the IBC container but also potentially affect its sealing reliability, safety during reuse, and ease of subsequent cleaning and maintenance. In scenarios involving bulk container replacement, modifying each IBC container is costly and also detrimental to maintaining the versatility of the IBC container as a standard packaging container.

[0005] Furthermore, factory compressed air typically has high pressure and may contain particles, moisture, or oil mist. If it is introduced directly into the IBC container without pressure regulation, filtration, and safety protection, problems such as uncontrollable inlet pressure, leaks at seals, container bulging, difficulty in releasing residual pressure in the air path, and material contamination can easily occur. Therefore, there is an urgent need for a pressurized auxiliary discharge device for high-viscosity liquids suitable for IBC containers. This device can introduce low-pressure gas, after pressure regulation and filtration, into the IBC container without modifying the container itself, through a detachable sealing cap or a modified screw cap that is sealed to the top filling port of the IBC container. Combined with pressure detection and a safety relief structure, it can achieve safe and controllable auxiliary discharge. Utility Model Content

[0006] The purpose of this invention is to provide a pressurized auxiliary discharge device for high-viscosity liquids in IBC containers, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a pressurized auxiliary discharge device for high-viscosity liquids in IBC containers, comprising a container body, a sealing cap component, an anti-static valve; an air source filter unit, a pressure control valve assembly, a safety relief valve, a pressure detection unit, an air inlet hose, and a connecting pipe; the sealing cap component is detachably installed at the filling port on the top of the container body, and a hose nozzle connector is provided on the sealing cap component; the air source filter unit is connected to the air inlet side of the pressure control valve assembly through the connecting pipe, and the air outlet side of the pressure control valve assembly is connected to the hose nozzle connector through the air inlet hose; the safety relief valve is connected in parallel on the connecting pipe between the air outlet side of the pressure control valve assembly and the air inlet hose; the pressure detection unit is located on the air path between the pressure control valve assembly and the hose nozzle connector, and is positioned close to the sealing cap component.

[0008] Furthermore, the sealing cap component includes a screw cap, a sealing element, and the hose nozzle connector. The screw cap is threadedly connected to the filling port at the top of the barrel. The sealing element is disposed between the screw cap and the filling port. The screw cap has an installation hole, and the hose nozzle connector passes through and is sealed and fixed at the installation hole.

[0009] Furthermore, the hose nozzle connector is located in the middle of the cap, and the hose nozzle connector is sealed to the cap.

[0010] Furthermore, the pressure control valve assembly includes a connecting bracket, a pressure regulating valve, a pressure gauge, and a pipeline filter. The pressure regulating valve, the pressure gauge, and the pipeline filter are all installed on the connecting bracket, and the pipeline filter, the pressure regulating valve, and the pressure gauge are connected sequentially along the gas flow direction.

[0011] Furthermore, the pressure regulating valve is provided with a pressure regulating handwheel, and the pressure regulating valve is also provided with a locking structure for restricting the rotation of the pressure regulating handwheel.

[0012] Furthermore, the safety relief valve is connected to the connecting pipe via a tee connector, and the safety relief valve has both an automatic pressure relief structure and a manual pressure relief structure.

[0013] Furthermore, the pressure gauge is used to detect the output pressure of the pressure control valve assembly, and the pressure detection unit is used to detect the pressure in the air path between the pressure control valve assembly and the hose nozzle connector.

[0014] Furthermore, the gas source filtration unit includes a particle filter and an oil-water separator, which are arranged sequentially along the gas flow direction, and the gas source filtration unit is separately arranged from the pressure control valve group.

[0015] Furthermore, the pressure control valve assembly is used to adjust the gas pressure entering the barrel to 0.02MPa to 0.05MPa, and the opening pressure of the safety relief valve is 0.06MPa.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model allows for the detachable installation of the sealing cap component at the top of the ton container and the connection of the hose nozzle connector to the air inlet hose. This enables the external pressure regulating air circuit to be connected to the inside of the ton container without making any openings, welding, or fixing modifications to the ton container body. This structure facilitates disassembly and reusability between different IBC ton containers and is suitable for scenarios involving batch container changes for discharging of high-viscosity liquids. 2. This utility model regulates the pressure of the gas entering the ton container through a pressure control valve group, and sets a safety pressure relief valve in parallel on the connecting pipe between the gas outlet side of the pressure control valve group and the gas inlet hose. When the gas pressure rises abnormally, it can release pressure in time, thereby reducing the risk of overpressure, bulging or leakage in the ton container and the gas inlet pipeline, and improving the safety of the pressurized assisted discharge process. 3. By placing the air source filtration unit upstream of the pressure control valve group and pre-treating the compressed air through a particle filter and an oil-water separator, the possibility of particles, moisture and oil mist entering the ton container with the gas can be reduced, the risk of high viscosity liquid being contaminated is reduced, and it is also beneficial to protect the pressure regulating valve, pressure gauge and other air circuit components. 4. This utility model integrates a pressure regulating valve, a pressure gauge, and a pipeline filter into a pressure control valve assembly by connecting a bracket, and sets up a pressure detection unit near the sealing cover component, so that the operator can know the output pressure of the valve assembly and the air pressure near the ton container, which facilitates on-site installation, pressure adjustment, operation monitoring, ton container replacement and disassembly, and subsequent maintenance.

[0019] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0020] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0021] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0022] Example 1 Please see Figures 1-2This embodiment provides a pressurized auxiliary discharge device for high-viscosity liquids in IBC containers, suitable for discharging high-viscosity liquids such as acrylic resin, epoxy resin, polyurethane resin, adhesives, and coating raw materials. The device includes a container body 1, a sealing cap component, an anti-static valve 3, an air source filter unit 7, a pressure control valve group 4, a safety relief valve 5, a pressure detection unit 6, an air inlet hose 8, and a connecting pipe 13. In this embodiment, the filling port at the top of the container body 1 is originally equipped with a screw cap for sealing the filling port. The sealing cap component can be formed using the existing screw cap 2 of the container body 1, or it can be formed using a replacement screw cap that matches the specifications of the filling port at the top of the container body 1. Specifically, when using the original screw cap 2, an installation hole can be made on the screw cap 2, and the hose nozzle connector 11 can be installed in the installation hole, allowing the hose nozzle connector 11 to connect with the air inlet hose 8. At the same time, the sealing element 10 ensures a sealed connection between the screw cap 2 and the filling port, thus adding a gas introduction function to the screw cap 2 while maintaining its original sealing function, forming a sealed cap component. When using a replacement screw cap, a structure for installing the hose nozzle connector 11 can be pre-set on the replacement screw cap, and a sealed connection can be formed by cooperating with the filling port at the top of the barrel 1. Both of the above methods only involve the setting or adjustment of the screw cap structure, without requiring any opening, welding, or fixing modifications to the plastic inner liner, outer frame, or filling port body of the barrel 1.

[0023] The sealing cap component includes a screw cap 2, a sealing element 10, and a hose nozzle connector 11. The screw cap 2 can be the original cap on the canister 1, or a replacement cap that matches the specifications of the canister opening at the top of the canister 1. The screw cap 2 has a mounting hole for installing the hose nozzle connector 11, which passes through and is sealed and fixed in this mounting hole. The screw cap 2 mates with the canister opening at the top of the canister 1; in this embodiment, the screw cap 2 is threadedly connected to the canister opening. The sealing element 10 is disposed between the screw cap 2 and the canister opening. When the screw cap 2 is tightened onto the canister opening, the sealing element 10 is pressed between the screw cap 2 and the canister opening, thereby achieving a sealed connection between the sealing cap component and the canister 1.

[0024] A hose nozzle connector 11 is mounted on the cap 2. In this embodiment, the hose nozzle connector 11 passes through the middle of the cap 2, with its outer end connected to the inlet hose 8 and its inner end communicating with the interior of the barrel 1. To ensure a tight seal between the hose nozzle connector 11 and the cap 2, a joint sealing ring can be provided between them. This sealing ring can be a fluororubber sealing ring or other pressure-resistant and chemical-resistant sealing rings. Thus, the sealing cap component serves both as a sealing structure for the filling port at the top of the barrel 1 and as an inlet for pressurized gas to enter the barrel 1.

[0025] In this embodiment, the main gas supply valve 9 is located upstream of the gas supply filter unit 7 and is used to control the entry of external gas into the device. The main gas supply valve 9 can be a manual ball valve, a shut-off valve, or other valves capable of controlling the on / off state of the gas path. During use, the operator supplies gas to the gas supply filter unit 7 by opening the main gas supply valve 9; during shutdown, barrel replacement, or maintenance, the operator closes the main gas supply valve 9 to cut off the external gas supply.

[0026] The air source filtration unit 7 is located upstream of the pressure control valve assembly 4. The air source filtration unit 7 includes a particle filter and an oil-water separator, which are arranged sequentially along the gas flow direction. After external compressed air enters the device, it first passes through the particle filter to remove solid particles, and then passes through the oil-water separator to remove moisture and oil mist from the compressed air, thereby reducing the risk of particles, moisture, or oil entering the tank 1 and contaminating the high-viscosity liquid inside. The air source filtration unit 7 is separate from the pressure control valve assembly 4 to facilitate filter element replacement, drainage maintenance, and on-site installation. It should be understood that the air source filtration unit 7 is a mature, existing structure.

[0027] The pressure control valve assembly 4 includes a connecting bracket 4a, a pressure regulating valve 4b, a pressure gauge 4c, and a pipeline filter 4d. The pressure regulating valve 4b, pressure gauge 4c, and pipeline filter 4d are all mounted on the connecting bracket 4a, forming an integrated valve assembly module. The connecting bracket 4a can be a metal mounting plate or a bent bracket, with mounting holes, pipeline clearance holes, or fixing holes for fixing the pressure regulating valve 4b, pressure gauge 4c, and pipeline filter 4d. The connecting bracket 4a primarily serves for mounting and support and is not a component for gas flow.

[0028] It should be noted that the integrated valve module mentioned here does not refer to a one-piece molded structure, but rather to multiple independent functional components being centrally installed through connecting bracket 4a to form a whole assembly, which facilitates overall handling, installation, replacement and maintenance.

[0029] The pipeline filter 4d, pressure regulating valve 4b, and pressure gauge 4c are connected sequentially along the airflow direction. The pipeline filter 4d is used to further filter the gas entering the pressure control valve assembly 4; the pressure regulating valve 4b is used to adjust the gas entering the pressure control valve assembly 4 to a low pressure range suitable for use in the tank 1; and the pressure gauge 4c is used to display the output pressure of the pressure control valve assembly 4. The pressure regulating valve 4b is equipped with a pressure adjusting handwheel, which the operator can rotate to adjust the output pressure of the pressure control valve assembly 4.

[0030] Furthermore, a locking structure can be provided on the pressure regulating valve 4b. The locking structure is used to restrict the rotation of the pressure regulating handwheel after the output pressure is regulated to the correct position, thereby reducing the risk of pressure changes caused by accidental contact or misadjustment on site.

[0031] The connecting pipe 13 forms a gas passage between the external air source and the intake hose 8. Specifically, the air source filter unit 7 is connected to the intake side of the pressure control valve assembly 4 via the connecting pipe 13, the outlet side of the pressure control valve assembly 4 is connected to the intake hose 8 via the connecting pipe 13, and the intake hose 8 is connected to the hose nozzle connector 11. The connecting pipe 13 may include one or more of the following: rigid pipe, flexible hose, compression fitting, threaded fitting, and tee fitting. In actual installation, the connecting pipe 13 may be in the form of stainless steel rigid pipe, high-pressure flexible hose, or a combination of both, depending on the site space arrangement.

[0032] The safety relief valve 5 is connected in parallel on the connecting pipe 13 between the outlet side of the pressure control valve group 4 and the inlet hose 8. Specifically, the safety relief valve 5 can be connected to the connecting pipe 13 through a tee connector, so that the safety relief valve 5 forms a bypass relief branch on the connecting pipe 13. It should be noted that the accompanying drawings are only used to illustrate the technical solution of this utility model in order to facilitate understanding of the connection relationship and installation position between the components. The installation form, connection position and pipeline arrangement of the safety relief valve 5 shown in the drawings are all exemplary embodiments. Without departing from the technical concept of this utility model, those skilled in the art can also use other connection structures or installation methods that can achieve the same function.

[0033] During normal operation, gas enters the intake hose 8 along the connecting pipe 13 and then enters the tank 1 through the hose nozzle connector 11. When the pressure in the connecting pipe 13 rises abnormally and reaches the opening pressure of the safety relief valve 5, the safety relief valve 5 opens and releases gas, thereby reducing the pressure on the tank 1 and the intake pipe. The pressure relief port of the safety relief valve 5 is not used as a normal intake passage; its exhaust direction can be downward or towards the side away from the operator to improve on-site operational safety.

[0034] The pressure detection unit 6 is located in the air path between the pressure control valve group 4 and the hose nozzle connector 11, and is located near the sealing cover component.

[0035] In this embodiment, the pressure detection unit 6 is a mechanical pressure gauge, which is connected via a connector to the connecting pipe 13 or the air inlet hose 8 near the sealing cover component. It is used to detect the air pressure on the side near the barrel 1. The pressure detection unit 6 has a different detection position than the pressure gauge 4c in the pressure control valve group 4. The pressure gauge 4c is mainly used to display the output pressure of the pressure control valve group 4, while the pressure detection unit 6 is mainly used to display the actual air inlet pressure on the side near the barrel 1. By setting two detection positions, the operator can monitor both the valve group output status and the actual air inlet status at the barrel end.

[0036] The working process of this embodiment is as follows: Before use, install the sealing cap component on the top of the container 1 at the filling port, tighten the cap 2 to the filling port, and seal it with the sealing element 10. Connect the air inlet hose 8 to the hose nozzle connector 11, and connect the external air source sequentially to the main air source valve 9, the air source filter unit 7, the pressure control valve group 4, and the connecting pipe 13. After confirming that the main air source valve 9 is closed and that the safety relief valve 5 and the pressure detection unit 6 are reliably installed, open the main air source valve 9, allowing compressed air to pass sequentially through the air source filter unit 7, the pipeline filter 4d, and the pressure regulating valve 4b. After confirming that the safety relief valve 5 and the pressure detection unit 6 are reliably installed, open the external air source, allowing compressed air to pass sequentially through the air source filter unit 7, the pipeline filter 4d, and the pressure regulating valve 4b. The operator adjusts the pressure regulating valve 4b using the pressure regulating handwheel and observes the reading of the pressure gauge 4c to ensure that the output pressure of the pressure control valve group 4 reaches the preset low pressure range.

[0037] During discharge, the anti-static valve 3 at the bottom of the tank 1 is opened. Pressure-regulated gas enters the tank 1 through the inlet hose 8 and hose nozzle connector 11, creating a slight positive pressure above the liquid surface. The high-viscosity liquid is discharged through the anti-static valve 3 under this slight positive pressure. During discharge, the operator can observe the reading on the pressure detection unit 6 to determine if the inlet pressure near the tank 1 is within a safe range. When the pressure abnormally increases, the safety relief valve 5 opens to release pressure and reduce the risk of overpressure.

[0038] After discharge, first close the anti-static valve 3, then close the main air supply valve 9 to cut off the external air supply. After the residual pressure in the connecting pipe 13, air inlet hose 8, and air inlet at the top of the tank 1 is released, remove the sealing cover component, which can then be transferred to the next ton tank for continued use. Because this device is detachably installed through the filling port at the top of the tank 1, it does not require drilling, welding, or other structural modifications to the tank 1 body, thus facilitating its reuse between different ton tanks.

[0039] In this embodiment, the pressure control valve assembly 4 can regulate the gas pressure entering the tank 1 to 0.02MPa to 0.05MPa, and the opening pressure of the safety relief valve 5 can be set to 0.06MPa. This pressure range can assist in the discharge of high-viscosity liquids while reducing the risk of the tank 1 bulging or being damaged due to excessive pressure. The above pressure values ​​are a preferred embodiment; in practical applications, they can be adjusted according to the tank specifications, material viscosity, discharge pipeline resistance, and on-site safety requirements.

[0040] Example 2 This embodiment further explains the filtration and sewage discharge and manual pressure relief structure based on Embodiment 1.

[0041] In this embodiment, a manual drain valve 12 is provided at the bottom of the pipeline filter 4d. When the pipeline filter 4d traps water, oil-water mixtures, or other liquid impurities during use, the operator can open the manual drain valve 12 to drain the liquid accumulated at the bottom of the pipeline filter 4d. By setting the manual drain valve 12, the impact of liquid accumulation inside the filter on gas flow and subsequent pressure regulation accuracy can be reduced, and on-site maintenance is also facilitated.

[0042] In addition to automatically releasing pressure when the set opening pressure is reached, the safety relief valve 5 can also have a manual pressure relief mechanism. The manual pressure relief mechanism can be a pull ring, a manual knob, a manual lever, or other means that allow the safety relief valve 5 to open and release pressure. When discharge is complete, when changing drums, or when abnormal operating conditions occur, operators can use the manual pressure relief mechanism to release residual pressure near the connecting pipe 13, the air inlet hose 8, and the sealing cover components, avoiding safety risks associated with disassembling the sealing cover components while they are not under pressure.

[0043] Example 3 This embodiment describes another implementation of the pressure detection unit 6 based on Embodiment 1.

[0044] In this embodiment, the pressure detection unit 6 is an electronic pressure sensor. The electronic pressure sensor is installed in the air path between the pressure control valve assembly 4 and the hose nozzle connector 11, and is located near the sealing cover component. The electronic pressure sensor detects the air path pressure near the tank 1 and outputs an electrical signal. This electrical signal can be transmitted to a display module, alarm module, or control module to facilitate pressure display, overpressure alarm, or automatic air supply cutoff.

[0045] Furthermore, this device may also include a pressure switch electrically connected to an electronic pressure sensor. When the electronic pressure sensor detects that the air pressure near the tank 1 exceeds a preset pressure value, the pressure switch activates and cuts off the air supply, thus providing additional protection beyond the pressure regulating valve 4b and the safety relief valve 5. This embodiment is suitable for applications with high requirements for on-site safety, automation, or unattended operation.

[0046] Example 4 This embodiment further explains the material and sealing structure of the sealing cover component based on Embodiment 1.

[0047] The seal 10 can be an EPDM sealing ring to meet the sealing requirements of commonly used filling ports on IBC containers. The hose nozzle connector 11 can be a stainless steel connector, and the sealing ring between the hose nozzle connector 11 and the cap 2 can be a fluororubber sealing ring. The cap 2 can be formed by modifying the existing filling port cap on the container body 1, or by processing a replacement cap that matches the specifications of the filling port on the top of the container body 1. When modifying the existing cap, an installation hole can be made in the middle of the cap 2, and the hose nozzle connector 11 can be sealed and installed in the installation hole; when processing a replacement cap, an installation hole can be pre-formed on the replacement cap and the hose nozzle connector 11 can be assembled. Neither of the above methods requires changing the filling port body, plastic inner liner, or external frame structure of the container body 1.

[0048] The housing or filter cup in the air source filter unit 7 that comes into contact with compressed air can be made of polycarbonate or aluminum alloy, and the sealing ring can be made of nitrile rubber or fluororubber. These material choices are suitable for use in environments containing water or oil in compressed air and help extend the service life of the filter unit.

[0049] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0050] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
