Description

Technical Field

[0001] The present invention relates to the technical field of agitators, and in particular to a balanced-weight agitator drive system and agitator system. Background Art

[0002] Stirring equipment is one of the important and indispensable equipment in the biopharmaceutical industry. Stirring equipment is divided into mechanical stirring and magnetic stirring. Mechanical stirring has poor sealing performance, so magnetic stirring devices have become the mainstream of stirring equipment today. Magnetic stirring devices usually include a tank body, stirring blades and a magnetic drive. Both the stirring blades and the magnetic drive are equipped with driving magnets. The magnetic drive drives the stirring blades to rotate in the tank body through the magnetic connection of two driving magnets. Products generally need to be mixed regularly in multiple tanks. If each tank is equipped with a magnetic drive, it will not only cause a waste of resources, but also greatly increase production costs. Summary of the invention

[0003] A first object of the present invention is to provide a balanced-weight agitator drive system.

[0004] A second object of the present invention is to provide a balanced weight agitator system.

[0005] In order to achieve the above-mentioned first purpose, the present invention provides a counterweighted agitator drive system, including a magnetic drive, a control box, an operating module and a mobile cart, the mobile cart including a frame, an operating part and a first roller group, the frame is provided with a front end and a rear end in the insertion direction, the control box and the magnetic drive are both arranged in the middle of the frame; the operating part and the operating module are both arranged at the rear end of the frame; the first roller group is arranged in the middle of the frame and below the control box, the control box is located between the magnetic drive and the operating module, and in the insertion direction, the distance from the magnetic drive to the control box is smaller than the distance from the operating module to the control box.

[0006] It can be seen from the above scheme that by arranging the control box and the magnetic drive in the middle of the frame, and arranging the operating part and the operating module at the rear end of the frame, the distance from the magnetic drive to the control box is smaller than the distance from the operating module to the control box, thereby achieving weight balance of the agitator drive system. The staff applies force to the operating part to make the rear end of the frame rotate downward or upward around the first roller group, thereby achieving a labor-saving effect.

[0007] A further solution is that the frame is provided with a fixing rod at the front end, and the extension direction of the fixing rod is perpendicular to the insertion direction; in the insertion direction, the distance from the fixing rod to the first roller group is smaller than the distance from the operating part to the first roller group.

[0008] It can be seen from the above scheme that in the process of the frame driving the fixing rod to rotate upward around the first roller group until the fixing rod is connected to the connecting frame, not only the rotation amplitude of the frame can be reduced, but also the driving force applied to the operating part can be reduced, thereby achieving a labor-saving effect.

[0009] A further solution is that a second roller set is provided at the front end of the frame, and in the vertical direction, the distance from the second roller set to the frame is smaller than the distance from the first roller set to the frame.

[0010] It can be seen from the above solution that by setting the distance from the second roller set to the frame to be smaller than the distance from the first roller set to the frame, the front end of the frame can rotate downward around the first roller set.

[0011] A further solution is that, in the insertion direction, the magnetic drive is located between the first roller set and the second roller set.

[0012] It can be seen from the above scheme that the center of gravity of the magnetic drive falls between the first roller group and the second roller group, which improves the walking stability of the mobile trolley and avoids the mobile trolley from rolling over accidentally.

[0013] A further solution is that the frame is also provided with a first support column and a first connecting plate in the middle, the first support column is vertically connected to the frame, the first connecting plate is connected to the end of the first support column, the first roller group is arranged on the bottom wall of the first connecting plate, and the control box is arranged on the top wall of the first connecting plate.

[0014] It can be seen from the above solution that by arranging the control box on the first connecting plate, the center of gravity of the control box falls on the first roller group, which is beneficial to reducing the resistance of the frame rotating around the first roller group.

[0015] A further solution is that a second support column is provided on the middle part of the first support column, the second support column extends toward the front end of the frame, and the second roller set is arranged on the second support column.

[0016] A further solution is that the center of gravity of the control box is located below the frame, and the center of gravity of the operating module is located below the frame.

[0017] It can be seen from the above scheme that by arranging the center of gravity of the control box and the operating module to be located below the frame, it is beneficial to lower the center of gravity and avoid the mobile car from tipping over during the rotation process.

[0018] A further solution is that a controller is provided in the control box, and the controller is electrically connected to the operating module and the magnetic drive respectively.

[0019] A further solution is that the operating part includes a connecting rod and a grip part, the extension direction of the connecting rod intersects with the insertion direction at an acute angle, the first end of the connecting rod is connected to the frame, and the second end of the connecting rod is connected to the grip part.

[0020] It can be seen from the above scheme that the connection rod and the handle are provided to facilitate the operation of the staff.

[0053] See also Figure 2 and Figure 3 The agitator drive system also includes a control box 11 and an operating module 111. The control box 11 is located in the middle of the frame 2 and on the first roller support foot 5, so that the center of gravity of the control box 11 is located below the frame 2, and the center of gravity of the agitator drive system falls on the first roller support foot 5. The operating module 111 is arranged at the rear end 22 of the frame 2 and on one side of the operating part 7, so that the staff can control the operating module 111 conveniently. The center of gravity of the operating module 111 is located below the frame 2. A controller is arranged in the control box 11, and the controller is electrically connected to the operating module 111 and the rotating motor respectively. The rotating motor drives the magnetic drive 1 to rotate. The operating module 111 is arranged between the two beams. The operating module 111 includes a speed control panel, which is electrically connected to the magnetic drive 1 and is used to control the rotation speed of the magnetic drive 1.

[0054] The total weight of the magnetic drive 1 and the rotary motor is greater than the weight of the operating module 111. In the Y direction, the distance from the magnetic drive 1 to the control box 11 is less than the distance from the operating module 111 to the control box 11. This is beneficial to achieve a balanced weight of the agitator drive system and reduce the resistance when the manual control frame 2 rotates around the center of the first roller group 53.

[0055] See also Figure 6 , the frame 2 rotates in the Z direction around the center of the first roller group 53, so that the front end 21 of the frame 2 is higher than the rear end 22 of the frame 2. At this time, the first roller group 53 is located on the ground, and the second roller group 63 is suspended above the first roller group 53, so that the fixing rod 3 can be connected to the second end of the connecting frame 101, so that the bearing 34 on the fixing rod 3 is embedded in the second limiting groove 103. At this time, the operating part 7 can be manually operated to make the bearing 34 roll on the connecting frame 101 along the Y direction, so that the moving trolley drives the magnetic driver 1 to move along the extension direction of the connecting frame 101 until the bearing 34 falls into the first limiting groove 102.

[0056] See also Figure 1 When the bearing 34 on the fixed rod 3 falls into the first limiting groove 102, the rear end 22 of the moving trolley can be lifted by the operating part 7, so that the moving trolley drives the magnetic driver 1 to rotate around the fixed rod 3 until the driving head of the magnetic driver 1 is connected to the connecting end of the stirring head. Then the position of the movable locking frame in the Y direction can be adjusted, and the movable locking frame can be rotated to connect the first swing arm 92 to the connecting frame 101, and the agitator drive system is locked to the tank body 100. At this time, the first roller support foot 5 and the second roller support foot 6 are both in a suspended state.

[0057] See also Figure 7When the agitator driving system moves between the two tanks 100, the first roller group 53 and the second roller group 63 are both located on the ground, and the first roller group 53 and the second roller group 63 rotate in the same direction. At this time, the line connecting the first roller group 53 and the second roller group 63 in the Y direction intersects with the plane where the frame 2 is located, and the plane where the frame 2 is located is parallel to the plane where the longitudinal beam 23 and the cross beam 24 are located. The rear end 22 of the frame 2 is higher than the front end 21 of the frame 2 in the Z direction, and the front end 21 of the frame 2 is higher than the second roller group 63 in the Z direction, so that the front end 21 of the frame 2 does not directly contact the ground, avoiding affecting the movement of the moving trolley. The distance from the first roller support foot 5 to the second roller group 63 is smaller than the distance from the first roller support foot 5 to the front end 21 of the frame 2, so that the second roller group 63 does not protrude from the front end 21 of the frame 2, affecting the connection between the fixing rod 3 on the front end 21 of the frame 2 and the connecting frame 101.

[0058] The above-mentioned embodiment is only a preferred embodiment of the present invention. In practical applications, a suitable locking rod can be selected for locking according to the specific position of the second limit groove of the connecting frame in the Y direction. This embodiment is compatible with a variety of connecting frames of different specifications, thereby improving the adaptability and practicality of the agitator drive system.
