Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, and in particular to a transfer device and a reaction vessel. Background Technology

[0002] During reactor fermentation experiments, a corresponding fermentation process controller is provided for the reactor, which includes a fixed-model stirring motor. In actual experiments, different brands of reactors are often used due to variations in fermentation processes. However, different reactor manufacturers typically use different stirring rod designs on their reactors. Therefore, theoretically, different models of stirring motors need to be adapted to accommodate the stirring rod designs of different manufacturers. However, there are compatibility issues between different models of stirring motors and existing controllers, and replacing the controller to adapt to different brands of reactors is also costly.

[0003] Therefore, there is an urgent need for a transfer device and a reaction vessel to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a transfer device and a reaction vessel that allows the stirring rod to be matched with a wider range of motor models via the transfer device, while maintaining stable transmission between the motor and the reaction vessel.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] An adapter is used to connect the output end of a motor and a stirring rod, wherein the stirring rod is installed inside a reaction vessel. The adapter includes:

[0007] The first adapter assembly includes a first connector and a second connector. The first connector is used to fix the reactor shell to the reactor body, and the second connector is used to fix the stirring rod to the reactor. The second connector is rotatably connected to the first connector.

[0008] The second adapter assembly includes a third connector and a fourth connector. The third connector is used for transmission connection with the output end of the motor. The fourth connector is fixedly connected to the third connector and is sleeved on the outside of the second connector and coaxially fixed.

[0009] The support member is fixed to the first connecting member, and the main body of the motor is provided with a plurality of positioning members, which are inserted into the support member.

[0010] As a preferred technical solution of the above-mentioned adapter, the first connecting member is a stepped shaft shape, including a first large diameter section, a first small diameter section, and a first shoulder formed between the first large diameter section and the first small diameter section. The support member is sleeved outside the first small diameter section and abuts against the first shoulder.

[0011] As a preferred technical solution of the above-mentioned adapter, the support member is provided with a threaded through hole, the threaded fastener is inserted into the threaded through hole and threadedly connected to the support member, and one end of the threaded fastener can abut against the first small diameter section in a direction perpendicular to the rotation axis of the second connector.

[0012] As a preferred technical solution of the above-mentioned adapter, the second connecting member is a stepped shaft shape, including a second large diameter section, a second small diameter section, and a second shoulder formed between the second large diameter section and the second small diameter section. The second small diameter section is located on the side of the second large diameter section facing away from the shell of the reactor. The fourth connecting member is sleeved on the outside of the second small diameter section and abuts against the second shoulder.

[0013] As a preferred technical solution of the above-mentioned adapter, the outer peripheral wall of the second small diameter section is provided with a plurality of spline protrusions, the plurality of spline protrusions are evenly distributed around the rotation axis of the second connector, and the inner peripheral wall of the fourth connector is provided with a plurality of spline grooves corresponding to each other.

[0014] As a preferred technical solution of the above-mentioned adapter, the third connector is connected to the output end of the motor via a spline structure.

[0015] As a preferred technical solution of the above-mentioned adapter, the support member is a cylindrical structure with an internal mounting cavity, and the fourth connector and the second connector are both located inside the mounting cavity.

[0016] As a preferred technical solution of the above-mentioned adapter, the support member is provided with a clearance opening and a mounting opening, the output end of the motor and / or the third connecting member can extend into the mounting cavity from the clearance opening, the mounting opening is located on the radial side of the clearance opening, and the positioning member is inserted into the mounting opening.

[0017] As a preferred technical solution of the above-mentioned adapter, multiple positioning elements are provided and evenly distributed around the axis of the output end, and multiple mounting ports are opened one-to-one.

[0018] A reaction vessel is also provided, including the aforementioned shell, the aforementioned stirring rod, the aforementioned motor, and the aforementioned adapter. The aforementioned stirring rod is rotatable relative to the aforementioned shell, and the aforementioned motor is fixed to the aforementioned shell through the aforementioned adapter and drives the aforementioned stirring rod.

[0019] The beneficial effects of this utility model are:

[0020] After the third connector of the second connecting assembly is connected to the output end of the motor, when the output end of the motor rotates, the third connector and the fourth connector rotate together. The first connector of the first connecting assembly is fixed to the shell of the reactor. The second connector connects the fourth connector and the stirring rod. The second connector and the first connector can rotate relative to each other. That is, when the motor starts, its output end drives the stirring rod to rotate relative to the shell of the reactor through the third connector, the fourth connector and the second connector, avoiding direct connection between the stirring rod and the output end of the motor, so that the stirring rod can be matched with more different models of motors through the adapter.

[0021] Furthermore, when the motor starts, its main body vibrates, causing varying degrees of relative movement between its output end and the adapter, and between the adapter and the stirring rod, leading to unreliable transmission. Therefore, in this embodiment, the support member maintains stability between the motor body and the reactor shell. One end of the support member is fixed to the reactor body via a first connector, and the other end is fixed to the motor body via a positioning member. Thus, the vibration of the motor body can be transmitted to the reactor shell through the support member. Generally, the reactor shell has a relatively large mass and is not prone to changes in its motion state, effectively suppressing motor vibration. Moreover, the support member can synchronize the relative movement between the motor body and the reactor shell, reducing the relative movement between the motor body, the adapter, and the reactor, and maintaining stable transmission.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0038] like Figures 1 to 6 As shown, this utility model provides a connecting device for connecting the output end 410 of a motor and a stirring rod. The stirring rod is installed inside a reaction vessel. The connecting device includes a first connecting assembly 100, a second connecting assembly 200, and a support member 300. The first connecting assembly 100 includes a first connecting member 110 and a second connecting member 120. The first connecting member 110 is fixed to the shell of the reaction vessel, and the second connecting member 120 is fixed to the stirring rod. The second connecting member 120 is rotatably connected to the first connecting member 110. The second connecting assembly 200 includes a third connecting member 210 and a fourth connecting member 220. The third connecting member 210 is driven to the output end 410 of the motor, and the fourth connecting member 220 is fixedly connected to the third connecting member 210. The fourth connecting member 220 is sleeved outside the second connecting member 120 and coaxially fixed. The support member 300 is fixed to the first connecting member 110. The main body of the motor has several positioning members 420 protruding from it, and the positioning members 420 are inserted into the support member 300.

[0039] For example, after the third connector 210 of the second connecting assembly is connected to the output end 410 of the motor, when the output end 410 of the motor rotates, the third connector 210 and the fourth connector 220 rotate together. The first connector 110 of the first connecting assembly is fixed to the shell of the reactor. The second connector 120 connects the fourth connector 220 and the stirring rod. The second connector 120 and the first connector 110 can rotate relative to each other. That is, when the motor starts, its output end drives the stirring rod to rotate relative to the shell of the reactor through the third connector 210, the fourth connector 220 and the second connector 120, avoiding direct connection between the stirring rod and the output end 410 of the motor, so that the stirring rod can be matched with more different models of motors through the adapter.

[0040] Furthermore, when the motor starts, its main body vibrates, causing varying degrees of relative movement between its output end and the adapter, and between the adapter and the stirring rod, leading to unreliable transmission. Therefore, in this embodiment, the support member 300 maintains stability between the motor body and the reactor shell. One end of the support member 300 is fixed to the reactor body via the first connector 110, and the other end is fixed to the motor body via the positioning member 420. Thus, the vibration of the motor body can be transmitted to the reactor shell through the support member 300. Generally, the reactor shell has a relatively large mass and is not prone to changes in its motion state, effectively suppressing motor vibration. Moreover, the support member 300 can synchronize the relative movement between the motor body and the reactor shell, reducing the relative movement between the motor body, the adapter, and the reactor, and maintaining stable transmission.

[0041] Optionally, the first connector 110 is a stepped shaft shape, including a first large diameter section 111, a first small diameter section 112, and a first shoulder 113 formed between the first large diameter section 111 and the first small diameter section 112. The support member 300 is sleeved on the outside of the first small diameter section 112 and abuts against the first shoulder 113.

[0042] Thus, the first shoulder 113 is used to provide limiting support for the support member 300. During the assembly process, when the axial end face of the support member 300 abuts against the first shoulder 113, it indicates that the support member 300 and the first connecting member 110 have been connected.

[0043] Optionally, the support member 300 has a threaded through hole, and the threaded fastener 310 is inserted into the threaded through hole and threadedly connected to the support member 300. One end of the threaded fastener 310 can abut against the first small diameter section 112 in a direction perpendicular to the rotation axis of the second connector 120.

[0044] For example, suppose the rotation axis of the second connector 120 is parallel to the first direction, and the insertion direction of the threaded fastener 310 and the support 300 is the second direction. The first direction is perpendicular to the second direction. By tightening the threaded fastener 310, the threaded fastener 310 can move relative to the support 300 along the second direction. When it is necessary to lock the support 300 and the first small diameter section 112, the end of the threaded fastener 310 can abut against the first small diameter section 112 along the second direction.

[0045] Furthermore, the first minor diameter section 112 is provided with a plug hole, and the end of the threaded fastener 310 can be inserted into the plug hole, which is a blind hole.

[0046] In other embodiments, the support 300 is interference-fitted with the first connector 110.

[0047] Optionally, the second connector 120 is a stepped shaft, including a second large-diameter section 121, a second small-diameter section 122, and a second shoulder 123 formed between the second large-diameter section 121 and the second small-diameter section 122. The second small-diameter section 122 is located on the side of the second large-diameter section 121 facing away from the reactor shell. The fourth connector 220 is sleeved on the second small-diameter section 122 and abuts against the second shoulder 123. Thus, the second shoulder 123 provides limiting support for the fourth connector 220. During assembly, when the axial end face of the fourth connector 220 abuts against the second shoulder 123, it indicates that the fourth connector 220 and the second connector 120 are connected.

[0048] Optionally, the outer peripheral wall of the second small diameter section 122 is provided with multiple spline protrusions, which are evenly distributed around the rotation axis of the second connector 120, and the inner peripheral wall of the fourth connector 220 is provided with multiple spline grooves corresponding to each other.

[0049] For example, the spline protrusion is a strip-shaped protrusion, the length of which is parallel to the rotation axis of the second minor diameter segment 122. The fourth connector 220 is sleeved on the outside of the second minor diameter segment 122, and the spline protrusion and spline groove are inserted one-to-one, thus realizing the transmission connection between the fourth connector 220 and the second connector 120 and restricting the relative rotation between them. Moreover, the arrangement of multiple spline protrusions around the rotation axis can make the force between the second connector 120 and the fourth connector 220 even, the transmission stable, and avoid local stress concentration.

[0050] Optionally, the third connector 210 is connected to the output end 410 of the motor via a spline structure.

[0051] For example, the output end 410 of the motor has a straight spline groove, and the third connector 210 has a corresponding spline protrusion. The spline protrusion is inserted into the spline groove, so that the output end 410 of the motor can drive the third connector 210 to rotate through the spline structure.

[0052] Optionally, the support member 300 is a cylindrical structure with an internal mounting cavity 320, and the fourth connector 220 and the second connector 120 are both located inside the mounting cavity 320.

[0053] For example, the support member 300 includes a peripheral sidewall and a side end face. The axial side of the peripheral sidewall and the end face are fixed to form a cylindrical structure with a cavity inside, namely the mounting cavity 320. The other end face of the peripheral sidewall can abut against the first shoulder 113 of the first connector 110. At this time, the second connector 120 is located in the mounting cavity 320. After the second adapter assembly 200 is assembled with the first adapter assembly 100, the third connector 210 can pass through the end face of the support member 300 and connect to the output end 410 of the motor, or the output end 410 of the motor can pass through the end face of the support member 300 and connect to the third connector 210.

[0054] Specifically, the support member 300 has a clearance opening 330 and a mounting opening 340. The output end 410 of the motor and / or the third connector 210 can extend into the mounting cavity 320 from the clearance opening 330. The mounting opening 340 is located on the radial side of the clearance opening 330, and the positioning member 420 is inserted into the mounting opening 340.

[0055] Thus, by inserting the positioning member 420 into the mounting port 340, and by arranging the mounting port 340 and the clearance port 330, the relative rotation between the motor body and the support member 300 can be restricted.

[0056] Optionally, multiple positioning elements 420 are provided, evenly distributed around the axis of the output end, and multiple mounting ports 340 are provided correspondingly.

[0057] In this way, multiple positioning components 420 can work together to resist the relative rotation between the motor and the support component 300, resulting in balanced stress and avoiding localized stress concentration.

[0058] A reaction vessel is also provided, including a shell, a stirring rod, a motor and the aforementioned adapter. The stirring rod is rotatable relative to the shell, and the motor is fixed to the shell via the adapter and drives the stirring rod.

[0059] Furthermore, the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the protection scope of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
