Description

Technical Field

[0001] This utility model relates to a mixing vessel interface structure, specifically, to a mixing vessel quick-connect interface. Background Technology

[0002] Quick-connect couplings on stirred tanks are highly efficient connection devices, primarily used to simplify the rapid assembly and disassembly of equipment components and ensure sealing connections. In process industries such as chemical, pharmaceutical, and food processing, stirred tanks require frequent replacement, addition, or removal of feed pipes, or frequent replacement of functional components such as agitators, temperature sensors, and cleaning devices. Traditional flange or threaded connections are cumbersome and time-consuming, while quick-connect couplings, through standardized snap-fit ​​or locking structures, achieve "plug and play," significantly shortening component replacement time and improving production flexibility and equipment utilization.

[0003] In existing technologies, such as the quick-connect assembly for a sealed liquid addition system for a reactor disclosed in Chinese Utility Model Patent CN202222059454.9, a fixed quick-connect ball valve is fixedly installed on the reactor. An intermediate quick-connect ball valve is connected to the fixed quick-connect ball valve, and a converter is connected through the intermediate quick-connect ball valve. One end of the converter is a quick-connect interface (flange connection end), which can be connected to the intermediate quick-connect ball valve using a quick-connect chuck. The other end is a threaded internal end, which can be connected to the threaded external end on a reagent bottle. In this design, installing too many redundant modules on the reactor not only reduces the functionality of the quick-connect connector but also results in a long quick-connect connector that occupies too much space.

[0004] Therefore, designing a quick-connect interface for a mixing vessel that allows for rapid replacement, addition, or reduction of the feed pipe, adapts to various functional accessories, and has a small size without occupying excessive vertical space has become an urgent technical problem to be solved.

[0005] In order to solve the above problems, people have been seeking an ideal technological solution. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a quick-connect interface for a mixing vessel. This interface allows for the rapid replacement, addition, or reduction of feed pipes in the mixing vessel, and it can also accommodate various functional accessories while maintaining a small size without occupying excessive vertical space.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: it includes a feed pipe, a valve body, and a quick-connect clamp. The bottom end of the feed pipe is welded to the mixing vessel. The valve body is installed to the top end of the feed pipe through the quick-connect clamp. Both the top end of the feed pipe and the bottom end of the valve body are provided with outer ring flanges. The quick-connect clamp is a grooved clamp. The groove in the quick-connect clamp is embedded with two abutting outer ring flanges, so that the two ports where the two outer ring flanges are located are connected in abutment.

[0008] Based on the above, the groove inside the quick-connect clamp is set as an open groove, and the axial section of the outer ring flange is set as a right-angled trapezoidal section, with the upper base and the inclined side of the axial section of the outer ring flange abutting the open groove.

[0009] Based on the above, the end face of the port of the outer ring flange is flush with the outer end face of the outer ring flange.

[0010] Based on the above, a sealing ring is provided between the two ports connected by the quick-connect clamp.

[0011] Based on the above, the sealing ring adopts a flat washer-O-ring composite sealing washer, and the end face of the interface with the outer ring flange is provided with a circular groove for embedding the O-ring.

[0012] Based on the above, the quick-connect interface of the mixing vessel also includes a sealing cap, the sealing cap having a sealing ring on its outer periphery, the sealing ring having an outer ring flange on its outer periphery, and the quick-connect clamp connecting the sealing ring to the port having the outer ring flange via the outer ring flange.

[0013] Based on the above, the inner end face of the sealing cap is provided with an embedding section, which is embedded in the inner cavity of the interface with the outer ring flange.

[0014] Based on the above, both ends of the valve body are provided with the outer ring flange, and the port of the feed pipe connected to the top end of the valve body is also provided with the outer ring flange.

[0015] Based on the above, the valve body adopts a manual butterfly valve.

[0016] Based on the above, the quick-connect clamp adopts a double-segment hinged clamp.

[0017] This utility model has substantial features and progress compared to the prior art. Specifically, the feed pipe can be quickly replaced, added, or reduced through quick-connect interfaces and valve bodies. It can also quickly install or replace various functional accessories through quick-connect interfaces. Moreover, the length of the feed pipe can be relatively short while meeting the requirement of using quick-connect clamps to connect related accessories. Therefore, the feed pipe does not need to occupy a lot of space on the surface of the mixing tank, thus saving the overall three-dimensional space occupied.

[0018] Meanwhile, the groove inside the quick-connect clamp is designed as an open groove, and it is matched with the outer ring flange with a right-angled trapezoidal cross section, which allows for quick installation of the feed pipe or accessories using the quick-connect clamp; the flat washer-O-ring composite sealing gasket form makes it easy for workers to quickly find the gasket installation position and has a good sealing effect; the sealing cap can be quickly installed on the top of the feed pipe or valve body through the quick-connect clamp, so as to seal the feed pipe or valve body when it is not in use.

[0025] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0026] Example 1

[0027] like Figures 1-5 As shown, the quick-connect interface of the mixing vessel in this embodiment includes a feed pipe 1, a valve body 2, and a quick-connect clamp 3. The bottom end of the feed pipe 1 is welded to the mixing vessel, specifically, it can be welded to the side wall or top surface of the mixing vessel, preferably to the top surface of the mixing vessel. The valve body 2 is installed to the top of the feed pipe 1 via the quick-connect clamp 3. Specifically, both the top port of the feed pipe 1 and the bottom port of the valve body 2 are provided with an outer ring flange 101. The outer ring flange 101 is integrally formed with the feed pipe 1 or the valve body 2, and can be a separate outer ring flange 101 protruding from the outer wall of the port of the feed pipe 1 or the valve body 2 (e.g., Figure 3 , Figure 4As shown), it can also be an outer ring flange 101 formed by grooving process; at the same time, the quick-connect clamp 3 adopts a groove clamp, and the groove 102 in the quick-connect clamp 3 connects the two end faces of the two outer ring flanges 101 by embedding two abutting outer ring flanges 101.

[0028] like Figure 5 As shown, the quick-connect clamp 3 adopts a double-segment hinged clamp. The quick-connect clamp 3 is divided into two independent semi-circular rings. One end of the two semi-circular rings is hinged together, and the other end of the two semi-circular rings can be locked together or separated by a manual threaded locking handle.

[0029] like Figure 1 , Figure 2 As shown, valve body 2 adopts a manual butterfly valve. In high-flow fluid applications, butterfly valves are usually one of the choices with the smallest valve body size. They are compact in structure and lightweight. Compared with gate valves, ball valves and other valves of the same diameter, butterfly valves occupy less space.

[0030] Based on the above structure, when the feed pipe of the mixing vessel needs to be replaced, added, or reduced, for example, different feed pipes can be installed on the top of different valve bodies 2, and then the valve bodies 2 with different feed pipes can be installed or removed using quick-connect clamps 3; when it is necessary to replace functional accessories such as stirring paddles, temperature sensors, and cleaning devices, the valve bodies 2 can be removed, and then the relevant functional accessories can be installed on the feed pipe 1 using quick-connect clamps 3.

[0031] Multiple feed pipes 1 can be welded onto the mixing vessel to enable the installation of multiple feed pipes or various functional accessories such as stirring paddles, temperature sensors, and cleaning devices.

[0032] Based on the relevant functions of the feed pipe 1, the length of the feed pipe 1 can be relatively short while still allowing for the use of quick-connect clamps 3 to connect to relevant accessories. Therefore, the feed pipe 1 does not need to occupy a lot of space on the surface of the mixing vessel, thus saving the overall three-dimensional space occupied.

[0033] Example 2

[0034] Based on Embodiment 1, the groove 102 inside the quick-connect clamp 3 is set as an open groove, and the axial section of the outer ring flange 101 is correspondingly set as a right-angled trapezoidal section. The upper bottom edge and the inclined edge of the axial section of the outer ring flange 101 abut against the open groove. The quick-connect clamp 3 and the outer ring flange 101 designed in this way can achieve a smoother fit, making it convenient for workers to quickly install and remove the quick-connect clamp 3.

[0035] Example 3

[0036] Based on Example 1 or Example 2, such as Figure 3 , Figure 4As shown, when the outer ring flange 101 is a separate outer ring flange 101 protruding from the outer wall of the port, the end face of the port with the outer ring flange 101 is flush with the outer end face of the outer ring flange 101. Figure 3 , Figure 4 In the middle, the outer ring flange 101 is distinguished by a dashed line, which allows the two ports to have a larger contact area.

[0037] Meanwhile, a sealing ring 103 is provided between the two outer ring flanges 101 embedded in the quick-connect clamp 3. The sealing ring 103 is a flat washer-O-ring composite sealing gasket, which includes an O-ring portion and a flat washer portion. The flat washer extends to both the inner and outer sides of the O-ring. The interface end face with the outer ring flange 101 has a circular groove for embedding the O-ring. The O-ring is held in the middle by the two interface end faces through the circular groove, and the flat washer is directly held in the middle by the two interface end faces. The flat washer-O-ring composite sealing gasket design makes it easy for workers to quickly locate the gasket installation position and provides a good sealing effect.

[0038] Example 4

[0039] Based on the above embodiments, both ends of the valve body 2 are provided with outer ring flanges 101, and the port of the feed pipe connected to the top end of the valve body 2 is also provided with an outer ring flange 101, which makes it convenient to replace different feed pipes without replacing the valve body 2.

[0040] Example 5

[0041] Based on the above embodiments, such as Figure 4 As shown ( Figure 4 The outer ring flange 101, the sealing ring 41, and the embedding section 42 are distinguished by dashed lines. The quick-connect interface of the mixing vessel also includes a sealing cover 4. The sealing cover 4 has a sealing ring 41 on its outer periphery, which seals the interface by contacting the interface end face. The sealing ring 41 has an outer ring flange 101 on its outer periphery, and the quick-connect clamp 3 connects the sealing ring 41 to the port with the outer ring flange 101 through the outer ring flange 101. The inner end face of the sealing cover 4 has an embedding section 42, which is embedded into the inner cavity of the interface with the outer ring flange 101, making it convenient for workers to quickly install the sealing cover 4 at the interface that needs to be sealed. The outer end face of the sealing cover 4 may have a handle, making it convenient for workers to quickly pick up the sealing cover 4.

[0042] The sealing cap 4 can be quickly installed on the top of the feed pipe 1 or valve body 2 using the quick-connect clamp 3. When the feed pipe 1 or valve body 2 is not in use, the feed pipe 1 or valve body 2 can be sealed to prevent contamination inside the mixing vessel.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
