Description

Technical Field

[0001] This utility model relates to the field of storage technology, specifically to a pneumatic stirring pressure tank. Background Technology

[0002] In the production and application of fluid materials such as coatings, adhesives, and inks, it is often necessary to store, mix, and pressurize the materials for transport.

[0003] Traditional storage containers often have the following problems:

[0004] 1. When materials are left to stand, sedimentation and stratification are likely to occur, affecting the uniformity during use;

[0005] 2. The separation of the simple stirring device and pressure storage function requires additional equipment, which increases the complexity of operation and space occupation;

[0006] 3. The opening and sealing of the container is cumbersome, especially when frequent cleaning or maintenance of internal components is required, resulting in low efficiency.

[0007] 4. Insufficient control precision in feeding and discharging can easily lead to material waste or unstable pressure, affecting production quality;

[0008] 5. Some pressure storage devices use a single material or a simple sealing structure, which can easily lead to leakage and damage in corrosive materials or high-pressure environments. This not only poses safety hazards but also shortens the service life of the equipment.

[0009] 6. The mixing mechanism of traditional equipment is mostly electrically driven, which poses a risk of spark ignition in flammable and explosive working environments, thus limiting its applicability.

[0010] Therefore, those skilled in the art have provided pneumatic stirring pressure tanks to solve the problems mentioned in the background art. Utility Model Content

[0011] To solve the above-mentioned technical problems, this utility model provides a pneumatic stirring pressure tank.

[0012] The device includes a pressure tank body, with a pressure tank cover installed at the upper end of the pressure tank body via a disassembly mechanism. The upper end of the pressure tank cover is connected to a material stirring mechanism for stirring the material inside the pressure tank body. A feeding control mechanism is connected to one side of the upper end of the pressure tank body, and three connection holes are opened at the upper end of the pressure tank cover. A pressure gauge, an air inlet pipe, and an exhaust pipe are respectively fixedly connected inside the three connection holes. The lower end of the pressure tank body is circular, and a discharge pipe is fixedly connected to the lower end of the pressure tank body. Control valves are fixedly connected inside the air inlet pipe, the exhaust pipe, and the discharge pipe.

[0013] Preferably, the disassembly mechanism is arranged in three sets in a circular array on the outer side of the upper end of the pressure tank. The disassembly mechanism includes a mounting frame, a mounting column, and a lifting eye screw. The mounting frame is fixedly connected to the outer side of the pressure tank. The lower end of the mounting column is rotatably connected to the inside of the mounting frame. The lifting eye screw is detachably connected to the inside of the mounting column.

[0014] Preferably, the upper end of the mounting column is provided with an internal threaded hole, the lifting eye screw is threadedly connected inside the internal threaded hole, and the upper end of the pressure tank cover is provided with three sets of installation limiting through grooves in a ring array.

[0015] Preferably, the material mixing mechanism includes a pneumatic motor, a mixing shaft, and mixing blades. The pneumatic motor is fixedly connected to the upper end of the pressure tank cover, the mixing shaft is fixedly connected to the output end of the pneumatic motor, and the mixing blades are fixedly connected to the outer side of the lower end of the mixing shaft.

[0016] Preferably, the feeding control mechanism includes a feeding hopper and a dust cover. The feeding hopper is fixedly connected to one side of the upper end of the pressure tank. An external thread is provided on the outer side of the upper end of the feeding hopper, and an internal thread is provided on the inner wall of the feeding hopper. The dust cover is detachably connected to the upper end of the feeding hopper through the external thread and the internal thread.

[0017] Preferably, a regulating valve is fixedly connected inside the feed hopper.

[0018] Preferably, both the pressure tank body and the pressure tank cover are made of stainless steel.

[0019] Preferably, a fixing ring is fixedly sleeved on the outer side of the pressure tank body, and four sets of fixing holes are opened inside the fixing ring, and a sealing ring is fixedly connected to the lower end of the pressure tank cover.

[0020] The technical effects and advantages of this utility model are as follows:

[0021] 1. Integrated functions improve operational efficiency.

[0022] The equipment integrates material storage, mixing, pressurization, and feed / discharge control functions into one unit, eliminating the need for an additional mixing device and reducing the connection steps between equipment.

[0023] For example, the material mixing mechanism directly drives the mixing shaft and mixing blades with a pneumatic motor, which can complete the mixing operation in real time inside the pressure tank, avoiding pollution and waste during the material transfer process and greatly improving production continuity.

[0024] 2. Strong mixing uniformity, ensuring material quality.

[0025] The material mixing mechanism is driven by a pneumatic motor, which has a stable output torque. Together with the mixing blades at the lower end of the mixing shaft, it can mix the materials in the tank in all directions.

[0026] Compared to traditional top-mounted single-blade agitators, this design effectively breaks up material sedimentation layers, making it particularly suitable for high-viscosity or easily stratified materials (such as pigment sedimentation in coatings), ensuring uniform concentration of discharged materials and improving the quality stability of subsequent construction or processing.

[0027] 3. Controllable pressure, adaptable to various scenarios

[0028] By combining the air inlet pipe, the air outlet pipe, and the pressure gauge, the air pressure inside the pressure tank can be flexibly adjusted, enabling stirring under normal pressure as well as pressurized conveying of materials under high pressure.

[0029] For example, in spraying operations, pressurization can make the material be discharged from the discharge pipe quickly and stably, reducing the risk of blockage and improving spraying efficiency.

[0030] 4. Easy disassembly and maintenance, reducing operational difficulty

[0031] The disassembly mechanism uses three sets of ring array mounting brackets, mounting columns, and lifting eye bolts. The lifting eye bolts cooperate with the installation limit slot of the pressure tank cover. Simply loosen the lifting eye bolts and rotate the mounting column to quickly open the pressure tank cover, which is convenient for cleaning or maintenance of the stirring blades, stirring shaft and other components inside the tank. Compared with the traditional flange connection sealing structure, the operation is simpler and saves maintenance time.

[0032] 5. Excellent sealing performance and high safety.

[0033] Both the pressure tank body and the pressure tank cover are made of stainless steel, which is high in strength and corrosion resistant. Combined with the tight fixing of the disassembly mechanism and the double threaded seal of the dust cover, it can effectively prevent material leakage and the entry of external impurities. At the same time, the control valves in the air inlet pipe, air outlet pipe and material outlet pipe can accurately control the flow of gas and materials, avoiding safety hazards caused by abnormal pressure.

[0034] 6. Precise feed control reduces material waste.

[0035] The regulating valve in the feeding control mechanism can flexibly adjust the feeding speed according to the material characteristics, avoiding accumulation or overflow caused by excessive feeding at one time. The dust cover design not only prevents dust from contaminating the material, but also forms a seal after feeding, ensuring the pressure stability inside the pressure tank.

[0036] 7. Stable installation and wide applicability.

[0037] The fixing ring and four sets of fixing holes on the outside of the pressure tank can securely install the equipment on the workbench or bracket, preventing the equipment from shaking or shifting even during high-pressure mixing or discharge. It is suitable for various scenarios such as factory workshops and laboratories. The choice of stainless steel material also allows it to be used in working conditions that come into contact with corrosive materials, expanding the application range of the equipment.

[0043] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose. Example 1

[0044] Please see Figures 1-3In this embodiment, a pneumatic stirring pressure tank is provided, including a pressure tank body 1. The lower end of the pressure tank body 1 is circular, and a discharge pipe 7 is fixedly connected to the lower end of the pressure tank body 1. The pressure tank body 1 serves as the main container for material storage and is made of stainless steel to ensure strength and corrosion resistance. The circular design at the lower end, combined with the discharge pipe 7, facilitates material discharge. A pressure tank cover 3 is installed on the upper end of the pressure tank body 1 via a disassembly mechanism 2. A sealing ring is fixedly connected to the lower end of the pressure tank cover 3. The pressure tank cover 3 and the sealing ring are used to seal the pressure tank body 1. The upper end is connected to a material stirring mechanism 4 for stirring the material inside the pressure tank 1. A feeding control mechanism 5 is connected to one side of the upper end of the pressure tank 1. The upper end of the pressure tank cover 3 has three connection holes 6. A pressure gauge, an air inlet pipe, and an exhaust pipe are fixedly connected inside the three connection holes 6, respectively. The pressure gauge is used to monitor the air pressure inside the tank, the air inlet pipe is used to introduce compressed gas for pressurization, and the exhaust pipe is used to release pressure. Control valves are fixedly connected inside the air inlet pipe, the exhaust pipe, and the discharge pipe 7. The control valves are used to control the on / off of gas / material.

[0045] The disassembly mechanism 2 is arranged in three sets in a ring on the outer side of the upper end of the pressure tank body 1. The disassembly mechanism 2 includes a mounting bracket 8, a mounting column 9, and a lifting eye screw 10. The mounting bracket 8 is fixedly connected to the outer side of the pressure tank body 1. The lower end of the mounting column 9 is rotatably connected to the inside of the mounting bracket 8. The lifting eye screw 10 is detachably connected to the inside of the mounting column 9. The upper end of the mounting column 9 has an internal threaded hole. The lifting eye screw 10 is threadedly connected to the inside of the internal threaded hole. The upper end of the pressure tank cover 3 has three sets of installation limiting through grooves 11 arranged in a ring on the upper end. By cooperating with the installation limiting through grooves 11 of the pressure tank cover 3, the pressure tank body 1 and the cover 3 can be quickly disassembled and fixed.

[0046] The material stirring mechanism 4 includes a pneumatic motor 12, a stirring shaft 13, and a stirring blade 14. The pneumatic motor 12 is fixedly connected to the upper end of the pressure tank cover 3, the stirring shaft 13 is fixedly connected to the output end of the pneumatic motor 12, and the stirring blade 14 is fixedly connected to the outer side of the lower end of the stirring shaft 13. The pneumatic motor 12 drives the stirring shaft 13 to rotate the stirring blade 14, thereby stirring the material in the tank and preventing sedimentation or solidification.

[0047] The feeding control mechanism 5 includes a feeding hopper 15 and a dust cover 16. The feeding hopper 15 is fixedly connected to one side of the upper end of the pressure tank 1. The outer side of the upper end of the feeding hopper 15 has an external thread, and the inner wall of the feeding hopper 15 has an internal thread. The dust cover 16 is detachably connected to the upper end of the feeding hopper 15 through the external and internal threads. A regulating valve 17 is fixedly connected inside the feeding hopper 15. The feeding hopper 15 is used for material feeding, and the dust cover 16 is double-fixed by the internal and external threads to achieve dust prevention and sealing. The regulating valve 17 can control the feeding speed and flow rate.

[0048] Both the pressure tank body 1 and the pressure tank cover 3 are made of stainless steel.

[0049] A fixing ring 18 is fixedly sleeved on the outside of the pressure tank body 1. The fixing ring 18 has four sets of fixing holes 19 inside. The fixing holes 19 are used to fix the pressure tank body 1 on the workbench or bracket to prevent displacement during operation.

[0050] Before using this utility model, the pressure tank 1 is installed in the designated position through the fixing hole 19 of the fixing ring 18 to ensure stability;

[0051] Place the pressure tank cover 3 on the upper end of the pressure tank body 1, then flip the mounting post 9 and lock it inside the mounting limit through groove 11. Finally, screw the lifting eye screw 10 into the internal thread hole of the mounting post 9 and tighten the lifting eye screw 10 to achieve the sealing and fixing of the tank body and the tank cover.

[0052] Ensure that the control valves of the air inlet pipe, exhaust pipe, and discharge pipe 7 are in the closed state.

[0053] When feeding is required

[0054] Rotate to open the dust cover 16 of the feed hopper 15, and use the external thread to engage with the internal thread of the feed hopper 15 to disassemble and pour the material to be processed into the feed hopper 15.

[0055] Based on the material characteristics, the feeding speed is controlled by adjusting the regulating valve 17 inside the feed hopper 15 to prevent material accumulation.

[0056] After feeding is completed, tighten the dust cover 16 with both internal and external threads to seal and prevent dust from entering the feed port.

[0057] When stirring the materials,

[0058] When the material stirring mechanism 4 is started, the pneumatic motor 12 is connected to the air source, and the output end drives the stirring shaft 13 to rotate. The stirring blades 14 at the lower end of the stirring shaft 13 rotate accordingly to uniformly stir the material in the barrel, preventing the material from settling, separating, or solidifying, such as paints, adhesives, and other materials that are prone to settling.

[0059] During the stirring process, the pressure inside the tank is monitored in real time by the pressure gauge on the pressure tank cover 3 to ensure that the initial state is normal pressure. If pressurized stirring is required, gas can be slowly introduced through the air inlet pipe.

[0060] When pressurization and pressure holding are required:

[0061] If the process requires stirring or discharging under pressure, connect to an external air compressor through the air inlet pipe, introduce compressed gas, open the air inlet pipe control valve, observe the pressure gauge until the target pressure is reached, then close the air inlet pipe control valve to maintain stable pressure inside the barrel.

[0062] If the pressure is too high, the exhaust pipe control valve can be opened to release some gas. After monitoring the pressure gauge to the appropriate level, the exhaust pipe control valve can be closed.

[0063] After mixing, confirm that the pressure inside the tank meets the discharge requirements. If pressurized discharge is required, maintain the pressure; if normal pressure discharge is required, the pressure can be released through the exhaust pipe first.

[0064] Open the control valve of the discharge pipe 7, and the material in the barrel will be discharged through the discharge pipe 7 under pressure or gravity, and enter the subsequent process, such as spraying, filling and other processes.

[0065] During the discharge process, the mixing mechanism can continuously stir at low speed to ensure the uniformity of the material.

[0066] After use, the equipment needs to be cleaned and maintained.

[0067] Close all control valves and completely release the pressure inside the tank through the vent pipe, ensuring the pressure gauge reads zero.

[0068] Loosen the eye bolt 10 of the disassembly mechanism 2 so that the eye bolt 10 is disengaged from the installation limit groove 11. Remove the pressure tank cover 3 and clean the tank body 1, stirring blade 14 and other components.

[0069] After maintenance, reinstall the pressure tank cover 3 and secure it using the disassembly mechanism 2, ready for the next use.

[0070] The entire process, through the coordinated operation of various mechanisms, achieves sealed storage, uniform mixing, and controllable feeding and discharging of materials. It is suitable for industrial scenarios that require a pressure environment or prevent material sedimentation, such as paint mixing and adhesive storage.
