Description

Technical Field

[0001] The utility model belongs to the technical field of ultrasonic contrast agent production, and particularly relates to a raw material mixing device for ultrasonic contrast agent production. Background Technique

[0002] An ultrasonic contrast agent, also known as a contrast agent, is a chemical product injected into human tissues or organs to enhance the imaging observation effect.

[0003] Currently, the Chinese utility model with the publication number CN220496259U discloses a raw material mixing device for CT contrast agent intermediate production, including a mixing device body, a feed pipe, and a fixing frame. By setting a control panel to start a timing conveying component, this utility model enables a quantitative conveying component to convey the required quantitative materials into a centralized blanking component, solving the problem that although the raw material mixing device can stably stir liquid materials during use, in actual use, since the feed port is located at the top of the raw material mixing device, and different liquids need to be continuously added during the production of the contrast agent, but users cannot conveniently weigh the liquid materials during the addition, which makes the raw material mixing device unable to mix the raw materials according to the component ratio, not only easily leading to defective products in the production of the contrast agent, but also easily causing the materials to spill during feeding, reducing the use effect of the raw material mixing device, and achieving the effect of quantitative feeding.

[0004] During the raw material mixing and processing of existing ultrasonic contrast agents, since the mixing device is generally driven by a motor to rotate the stirring rod in a single direction inside, the raw materials of the ultrasonic contrast agent can only flow in a fixed direction. This mixing method has poor effects, and it is difficult for the raw materials to quickly and fully blend together, greatly affecting the mixing and processing efficiency of the ultrasonic contrast agent raw materials. Moreover, the stirring rod inside the mixing device is generally bolted to the bottom of the barrel cavity, which can ensure that the mixing can be carried out even when the liquid level of the raw materials is relatively low. However, due to the too low setting of the stirring rod, when the liquid level is relatively high, it is difficult for the stirring rod to drive the raw materials above to be mixed during rotation, easily causing the ultrasonic contrast agent raw materials to be unevenly mixed and having low practicability. Content of the Utility Model

[0005] The purpose of the utility model is to provide a raw material mixing device for ultrasonic contrast agent production, which has the advantages of being convenient to adjust the height of the mixing stirring rod according to the liquid level of the ultrasonic contrast agent raw materials, enabling the mixing stirring rod to perform multi-directional stirring, and improving the mixing efficiency.

[0006] The above technical object of the utility model is achieved through the following technical solutions: A raw material mixing device for the production of ultrasonic contrast agents, including a support frame, inside which a mixing barrel is bolted. On the top of the mixing barrel, a connecting rod bolted to the support frame is welded. On the top of the support frame, a first motor is bolted. The output end of the first motor is bolted with a driving barrel rod that is rotationally connected through the bottom of the connecting rod. Inside the driving barrel rod, a hexagonal rotating rod is slidably connected through. On both sides of the bottom of the hexagonal rotating rod, mixing stirring rods are rotatably connected. At one end of each of the two mixing stirring rods close to the inside of the hexagonal rotating rod, a second bevel gear is bolted. At the bottom of the inner cavity of the mixing barrel, a fixed rod that is slidably connected through the bottom of the hexagonal rotating rod is welded. On the surface of the fixed rod, a sliding sleeve is slidably sleeved. On the top and bottom of the surface of the sliding sleeve, first bevel gears meshing with the second bevel gears are symmetrically and fixedly sleeved.

[0007] By adopting the above technical solution, by turning on the first motor to drive the hexagonal rotating rod to rotate, the mixing stirring rods can rotate themselves while rotating around the center of the hexagonal rotating rod. Thus, the raw materials of the ultrasonic contrast agent are stirred in multiple directions, improving the mixing effect of the raw materials of the ultrasonic contrast agent. By turning on the second motor to drive the threaded rod and the threaded sleeve to be threadedly engaged, the hexagonal rotating rod is adjusted and supported in terms of lifting, so that the mixing stirring rods can move to different heights to stir the raw materials of the ultrasonic contrast agent. Reducing the phenomenon of uneven mixing of the raw materials of the ultrasonic contrast agent and improving the practicability.

[0008] The utility model is further provided as follows: A second motor is bolted to the bottom of the mixing barrel. The output end of the second motor is bolted with a threaded rod that is rotatably connected inside the fixed rod. On the surface of the threaded rod, a threaded sleeve is threadedly sleeved. On the surface of the threaded sleeve, a connecting block welded to the inner surface of the sliding sleeve is welded. On both sides of the surface of the fixed rod, chutes through which the connecting block is slidably connected are opened.

[0009] By adopting the above technical solution, the phenomenon of uneven mixing of the raw materials of the ultrasonic contrast agent is reduced, and the practicability is improved.

[0010] The utility model is further provided as follows: On both sides of the surface of the mixing stirring rod, turning stirring blades are welded.

[0011] By adopting the above technical solution, the stirring effect on the raw materials of the ultrasonic contrast agent when the mixing stirring rod rotates itself is improved.

[0012] The utility model is further provided as follows: On one side of the top of the mixing barrel, a feeding port is opened. On one side of the bottom of the mixing barrel, a discharge valve is fixedly communicated.

[0013] By adopting the above technical solution, the raw materials of the ultrasonic contrast agent can be added into the mixing barrel through the feeding port, and at the same time, the mixed ultrasonic contrast agent can be discharged by using the discharge valve.

[0014] The present utility model is further configured such that: one side of the surface of the support frame is bolted with an observation window.

[0015] Adopting the above technical solution facilitates observing the mixing condition of the ultrasound contrast agent raw materials inside the mixing barrel.

[0016] The present utility model is further configured such that: both ends of the surface of the sliding sleeve are welded with limiting disks, and the inside of the hexagonal rotating rod is rotatably connected with balls that are slidably connected to the limiting disks.

[0017] Adopting the above technical solution enables the sliding sleeve to push the hexagonal rotating rod to slide up and down, and at the same time reduces the friction force when the hexagonal rotating rod slides at both ends of the sliding sleeve.

[0018] The present utility model is further configured such that: a sealing ring bonded to the hexagonal rotating rod is slidably sleeved on the surface of the fixed rod.

[0019] Adopting the above technical solution improves the sealing performance and prevents the ultrasound contrast agent raw materials from seeping into the interior.

[0020] In summary, the present utility model has the following beneficial effects:

[0021] By starting the first motor to drive the hexagonal rotating rod to rotate, the mixing stirring rod can rotate itself while rotating around the center of the hexagonal rotating rod. Thus, the ultrasound contrast agent raw materials are rotated and stirred in multiple directions, improving the mixing effect of the ultrasound contrast agent raw materials; by starting the second motor to drive the threaded rod and the threaded sleeve to be threadedly engaged, the hexagonal rotating rod is lifted and adjusted and supported, so that the mixing stirring rod can move to different heights to stir the ultrasound contrast agent raw materials. The phenomenon of uneven mixing of the ultrasound contrast agent raw materials is reduced, and the practicability is improved. BRIEF DESCRIPTION OF THE DRAWINGS
