Description

Technical Field

[0001] This invention relates to the field of stainless steel medium bulk container technology, specifically to a stainless steel medium bulk container. Background Technology

[0002] For liquid preparations such as pharmaceutical solutions, drugs can be dispersed in a liquid medium in a certain form to form a liquid dispersion system. They are convenient to prepare and use, and can be adjusted according to the needs of medication. Therefore, stainless steel medium-sized bulk containers are required to store the liquid.

[0003] In existing technologies, medium-sized stainless steel bulk containers mainly consist of a barrel body and an external metal frame. The barrel body and frame columns are often connected by direct lap welding without a dedicated flange structure. The top of the container lacks overall reinforcing ribs, relying solely on the frame itself for support and reinforcement. The corners of the connecting frame are exposed welded structures without protective components such as corner protectors. During production, the lack of a standardized flange positioning structure for the connection between the barrel body and the columns necessitates repeated manual calibration of their relative positions before welding, making it difficult to adapt to the requirements of automated welding production lines. However, on the one hand, the connection strength of the direct lap welding between the barrel and the column is limited. The top lacks reinforcing ribs and the corners are not protected by corner pads. This makes the connection parts prone to plastic deformation or even weld cracking when the container is stacked, forklifted, or accidentally collided. Especially in the case of a full-load drop, stress tends to concentrate in the weak weld area, which can lead to tank damage and leakage. This significantly shortens the overall service life of the container and increases the cost of frequent container replacement or maintenance for users. On the other hand, the connection method without flanges requires precise manual calibration and positioning, which cannot meet the requirements of automated production for process standardization and precise positioning. This results in low production efficiency, high labor costs, and difficulty in achieving large-scale mass production.

[0004] In light of this, we are introducing a medium-sized stainless steel bulk container. Summary of the Invention

[0005] The purpose of this invention is to provide a stainless steel medium-sized bulk container to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a medium-sized stainless steel bulk container, comprising: a bent column and an inclined collection section; The inner side of the bent column is provided with a flanged and rolled welded barrel body. A maintenance hole is opened in the center of the barrel body surface. The top of the barrel body is provided with an upper flanged plate, which is welded to the bent column. The bottom of the barrel body is provided with a lower flanged plate, which is welded to the bent column. An inclined collecting part is located at the bottom of the barrel, and an elbow pipe is connected to the surface of the inclined collecting part. A drain port is opened on one side of the elbow pipe, and a ball valve is provided on the surface of the elbow pipe on the side of the drain port. A connecting frame is welded to the top of the bent column. A feed port is opened on one side of the top of the barrel, and a vent is connected to the side of the feed port on the top of the barrel.

[0007] Preferably, the top of the barrel is integrally stamped with reinforcing ribs; the integral stamping process makes the reinforcing ribs and the barrel form a solid whole, without the need for additional welding, which simplifies the production process and avoids the potential corrosion risks at the welding parts.

[0008] Preferably, a safety valve is provided on the top of the barrel on the other side of the feed inlet; the safety valve adopts a spring-type automatic pressure relief structure, and the set pressure value is precisely determined according to the pressure bearing capacity of the barrel. When the air pressure in the barrel exceeds the set value due to factors such as liquid evaporation and temperature changes, the safety valve can automatically open to relieve pressure, and automatically close after the air pressure drops to a safe range, without the need for manual operation throughout the process.

[0009] Preferably, corner protectors are installed at the four corners of the connecting frame. The corner protectors are made of highly elastic rubber material and have good cushioning performance. They are attached to the four corners of the connecting frame with strong adhesive to prevent the corners of the connecting frame from colliding with the transport vehicle or other items during the transportation of stainless steel medium-sized bulk containers.

[0010] Preferably, angle iron plates are welded to the inner bottom of the bent column, and feet are welded to the bottom of the bent column and the angle iron plates respectively; anti-slip rubber pads are installed at the bottom of the feet, which can increase the friction with the ground, prevent the stainless steel medium bulk container from sliding on the ground, avoid the feet from directly contacting the ground and causing wear, extend the service life of the feet, and reduce the pressure on the ground when the stainless steel medium bulk container is placed, protecting the ground from damage.

[0011] Preferably, a reinforcing plate is welded between the bent column and the angle iron plate. The reinforcing plate is a triangular steel plate, which is fully welded to both the bent column and the angle iron plate. The triangular structure has a stability advantage and can further enhance the strength of the connection between the bent column and the angle iron plate.

[0012] Preferably, the top of the bent column is provided with a locking element on the surface of the maintenance hole.

[0013] Compared with the prior art, the beneficial effects of the present invention are: (1) Through the design of the flanged roll welding connection between the barrel and the bent column, the top reinforcing rib and the corner pad of the connecting frame, the structural strength and damage resistance of each component of the stainless steel medium bulk container are enhanced, the overall service life of the stainless steel medium bulk container is extended, and the user's cost is reduced. At the same time, the upper plate flange of the barrel top is welded to the bent column, and the lower plate flange of the barrel bottom is welded to the bent column, which enables automated production. (2) In the liquid discharge process, the bottom inclined collection part guides the liquid to the lowest point and flows to the discharge port through the elbow pipe. The staff can flexibly control the discharge speed or stop the discharge at any time through the ball valve. The operation is simple and easy to control. (3) In terms of maintenance, the maintenance hole in the center of the barrel provides a convenient passage for internal inspection, maintenance and cleaning. Staff do not need to disassemble the entire barrel. They can directly enter through the maintenance hole or use tools to operate, saving maintenance time and labor costs and improving overall efficiency. Attached Figure Description

[0017] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0018] Please see Figure 1-5 The present invention provides a technical solution: a medium-sized stainless steel bulk container, comprising: a bent column 1, a barrel body 14 with a flanged and rolled welded on the inner side of the bent column 1, a maintenance hole 3 with a DN400 opening at the center of the surface of the barrel body 14 to facilitate workers to periodically enter the barrel body 14 to inspect, clean impurities or repair internal parts, an upper flange 18 with the top of the barrel body 14 and welded to the bent column 1, and a lower flange 19 with the bottom of the barrel body 14 and welded to the bent column 1; An inclined collecting section 16 is located at the bottom of the tank body 14, and an elbow pipe 12 is connected to the surface of the inclined collecting section 16. The elbow pipe 12 is a DN50 stainless steel pipe fitting, which is connected to the inclined collecting section 16 by argon arc welding. The weld joint has been pressure tested to ensure pressure resistance. A drain port 10 is opened on one side of the elbow pipe 12, and a ball valve 11 is installed on the surface of the elbow pipe 12 on the side of the drain port 10. The ball valve 11 is a DN50 manual stainless steel ball valve with a PTFE core, which is flexible in opening and closing and has excellent sealing performance. It can accurately control the liquid discharge flow rate and closes when... There is no leakage. The top of the bent column 1 is welded with a connecting frame 13. The top side of the barrel 14 has a feed port 6, which is a DN50 circular opening. The opening is equipped with a flange, which can be bolted to the external feed pipe. Asbestos gaskets are placed between the flanges to improve the sealing. The top of the barrel 14 is connected to a vent 7 on the side of the feed port 6. The vent 7 is a DN25 stainless steel pipe with a dustproof and breathable cap installed at the pipe opening to prevent dust and debris from entering the barrel. At the same time, it ensures that the air pressure inside the barrel is balanced with the outside air pressure, avoiding air pressure blockage problems when liquid is input or discharged.

[0019] The top of the barrel 14 is integrally stamped with reinforcing ribs 4, which can enhance the deformation resistance of the top of the barrel and prevent the top of the barrel from being dented due to the placement of tools or external pressure, while not affecting the storage space inside the barrel.

[0020] The top of the barrel 14 is equipped with a safety valve 5 on the other side of the feed inlet 6. The safety valve 5 is a spring-loaded safety valve. When the pressure inside the barrel 14 exceeds the set value due to liquid evaporation and temperature rise, the safety valve 5 will automatically open to release pressure. After the pressure drops to a safe range, it will automatically close, effectively preventing the barrel 14 from exploding due to overpressure and ensuring safe use.

[0021] Corner protectors 2 are installed at the four corners of the connecting frame 13. The corner protectors 2 are made of highly elastic rubber and are attached to the four corners of the connecting frame 13 by strong adhesive or countersunk screws. They can buffer the impact of collisions during the handling and stacking of stainless steel medium bulk containers, prevent the four corners of the connecting frame 13 from deforming, and reduce the noise generated by collisions.

[0022] Angle iron plates 8 are welded to the inner bottom of the bent column 1. The angle iron plates 8 are #5 angle irons made of Q235 steel and are connected to the bent column 1 by double-sided welding, which can enhance the load-bearing stability of the bottom of the bent column 1. Support legs 9 are welded to the bottom of the bent column 1 and the angle iron plates 8, respectively. The support legs 9 are cylindrical stainless steel parts with anti-slip rubber pads installed at the bottom to increase the friction with the ground and prevent the stainless steel medium bulk container from sliding on the ground.

[0023] A reinforcing plate 15 is welded between the bent column 1 and the angle iron plate 8. The reinforcing plate 15 is a triangular steel plate, which is fully welded to the bent column 1 and the angle iron plate 8 to form a triangular support structure. This structure can further disperse the longitudinal pressure borne by the bent column 1 and prevent the column from bending and deforming due to long-term load.

[0024] The top of the bent column 1 is provided with a locking element 17 on the surface of the maintenance hole 3. The locking element 17 can be used to lock and open the cover plate on the surface of the maintenance hole 3, thereby controlling the opening and closing of the maintenance hole 3.

[0025] Specifically, in use, the bent column 1 serves as the core supporting component of the stainless steel medium bulk container. The angle iron plate 8 welded to the inner bottom of the bent column 1 forms a stable triangular support structure with the bent column 1. At the same time, the support legs 9 welded to the bottom of both increase the contact area with the ground, effectively distributing the overall weight of the stainless steel medium bulk container and preventing the container from tilting or sinking due to the increased weight after liquid storage. In addition, the reinforcing plate 15 welded between the bent column 1 and the angle iron plate 8 further strengthens the connection strength and can resist the external impact that the stainless steel medium bulk container may be subjected to during handling and use, ensuring that the entire support frame remains stable for a long time and providing a reliable installation foundation for the container 14. The connecting frame 13 is welded to the top of the bent column 1, which not only plays a lateral fixing role for the bent column 1 and prevents the column from deforming due to uneven force, but the corner protectors 2 installed at its four corners can also prevent the corners of the connecting frame from colliding with other objects during the transportation or use of the stainless steel medium bulk container, thus extending the service life of the connecting frame and reducing the noise generated during collisions. The tank body 14 is connected to the inner side of the bent column 1 by a flanging and rolling welding process. Flanging and rolling welding not only ensures the sealing of the connection between the liquid storage tank and the bent column 1, preventing liquid from leaking from the connection gap, but also enhances the structural strength of the connection part, enabling the liquid storage tank to stably withstand the pressure of the internal liquid. At the same time, the advantages of flanging and rolling welding include that it is not easy to open the gap during long-term use and transportation, and that it can be automated in the later stage, making it more convenient to use. The maintenance hole 3 centrally located on the surface of the tank body 14 provides a convenient passage for staff to inspect, maintain and clean the inside of the storage tank. When it is necessary to inspect the inside of the storage tank, staff can directly enter the tank through the maintenance hole 3 or use tools to operate without disassembling the entire storage tank, which greatly saves maintenance time and cost. At the same time, the upper plate flange 18 at the top of the tank body 14 is welded to the bending column 1, and the lower plate flange 19 at the bottom of the tank body 14 is welded to the bending column 1, so that automated production can be achieved during the production process. The upper and lower ends of the tank body 14 are welded to the upper plate flange 18 and the lower plate flange 19, respectively. The reinforcing rib 4, which is integrally stamped on the top of the tank body 14, can effectively enhance the structural strength of the top of the liquid storage tank and prevent the liquid storage tank from denting or deforming due to the force on the top (such as placing other items or external pressure) during the liquid storage process, thus ensuring the overall structural stability and service life of the liquid storage tank. The inlet 6 on one side of the top of the tank 14 is the main channel for liquid input. External liquid enters the tank 14 through the inlet 6 for storage. During the liquid input process, the vent 7 connected to the side of the inlet 6 on the top of the tank 14 plays a key role. It can balance the air pressure inside and outside the storage tank. When liquid enters the storage tank through the inlet 6, the air inside the tank can be discharged through the vent 7 to avoid the liquid not being able to be input smoothly due to excessive air pressure inside the tank. At the same time, during the subsequent liquid discharge or use process, external air can also enter the tank through the vent 7 to prevent negative pressure inside the tank from affecting the normal flow of liquid, ensuring the smoothness of liquid input and subsequent use. The inclined collecting part 16 at the bottom of the barrel 14 serves to guide the flow of liquid. Because the inclined collecting part 16 is inclined, the liquid inside the barrel 14 will automatically collect at the lowest point of the inclined collecting part 16 under the action of gravity, and then flow to the drain port 10 through the elbow pipe 12 connected to the surface of the inclined collecting part 16. The drain port 10 opened on one side of the elbow pipe 12 is the channel for liquid discharge, and the ball valve 11 set on the surface of the elbow pipe 12 on the side of the drain port 10 is used to control the discharge of liquid. The operator can control the discharge of liquid by opening or closing the ball valve 11, such as adjusting the discharge speed of liquid, stopping the discharge at any time, etc. It is convenient to operate and easy to control, meeting the needs of liquid discharge in different scenarios. The safety valve 5, located on the top of the tank 14 on the other side of the inlet 6, is an important component to ensure the safe use of the storage tank. When the internal pressure of the tank 14 rises due to factors such as liquid evaporation and temperature changes, and exceeds the set pressure value of the safety valve 5, the safety valve 5 will automatically open to discharge excess gas from the tank, reduce the internal pressure, and prevent safety accidents such as explosion of the storage tank caused by excessive internal pressure. When the internal pressure drops to a safe range, the safety valve 5 will automatically close, ensuring that the internal pressure of the storage tank is always in a safe state, providing reliable protection for the safe use of stainless steel medium-sized bulk containers. Meanwhile, the barrel 14 can be stacked for convenient transportation, and the protective device can be replaced at any time without damaging the barrel 14.
