Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, specifically a reaction vessel for preparing controlled-release dry suspensions. Background Technology

[0002] In the industrial production of sustained-release dry suspensions, the reactor is the core equipment for material mixing, reaction and formulation. Its structural design directly affects the uniformity of material mixing, production efficiency and the quality stability of the final formulation.

[0003] The existing Chinese patent publication number CN222305807U, entitled "A Reactor for Preparing a Controlled-Release Dry Suspension," explicitly states in its abstract that "This utility model discloses a reactor for preparing a controlled-release dry suspension, comprising a shell with multiple support legs installed at the lower end of the shell, a metal inner liner extending through the shell and fixedly connected to the shell, and an ultrasonic generating component installed on the side wall of the metal inner liner; a mixing mechanism including a motor installed at the upper end of the metal inner liner, the output shaft of the motor extending into the metal inner liner and equipped with multiple stirring rods; a heat dissipation mechanism for dissipating heat from the ultrasonic generating component; a feeding port at the inner top of the metal inner liner, and a discharge port at the inner bottom of the metal inner liner, with a manual valve installed in the discharge port. This reactor, through the use of the mixing mechanism in conjunction with the ultrasonic generating component, effectively improves the mixing rate and reduces the adhesion of easily adhering impurities, while also facilitating subsequent cleaning."

[0004] However, in the existing technology, the materials are mixed and stirred only by stirring rod. However, during the stirring process, since the inner liner of the reaction vessel is fixed, the stirring range of the stirring rod is limited. The materials near the inner wall of the inner liner are prone to forming a stirring dead zone, making it difficult to mix them fully with the materials in the center. Furthermore, some materials are deposited at the bottom of the liner due to gravity, and the stirring rod cannot act on this area. The deposited materials cannot effectively participate in the reaction, affecting the yield, and may also deteriorate due to long-term deposition, thus affecting the quality of the formulation. Utility Model Content

[0005] The purpose of this invention is to provide a reaction vessel for preparing controlled-release dry suspensions, so as to solve the problem of uneven mixing between the inner wall and the bottom of the existing structure mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A reaction vessel for preparing a sustained-release dry suspension includes a reaction chamber and mounting components;

[0008] The mounting components include a mounting frame and a base. A support frame is provided in front of the base. A partition is provided around the inner side of the reaction chamber. A stirring rod is rotatably installed inside the reaction chamber.

[0009] In a preferred embodiment of this utility model, the reaction chamber is rotatably mounted inside the mounting frame, and the front two sides of the mounting frame are rotatably mounted on the top of the support frame.

[0010] In a preferred embodiment of this utility model, a first motor is provided at the rear of the reaction tank, and the output end of the first motor is connected to a stirring rod.

[0011] In a preferred embodiment of this utility model, a second motor is provided at the top rear of the mounting bracket, and a drive gear is provided on the output end of the second motor.

[0012] In a preferred embodiment of this utility model, an external gear is provided on the outer rear side of the reaction tank, and the drive gear meshes with the external gear.

[0013] In a preferred embodiment of this utility model, a limiting rail is provided at the rear of the base, a limiting block is slidably provided inside the limiting rail, a connecting rod is hinged to the top of the limiting block, and the connecting rod is hinged to the bottom of the rear of the mounting frame.

[0014] In a preferred embodiment of this utility model, a hydraulic push rod is provided behind the limiting rail, and the telescopic end of the hydraulic push rod is connected to the limiting block.

[0015] In a preferred embodiment of this utility model, a feed inlet is provided at the top of the reaction chamber, and a discharge outlet is provided at the front bottom of the reaction chamber. Both the feed inlet and the discharge outlet are switched by electromagnetic valves.

[0016] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0017] Beneficial effects: When the stirring rod mixes the dry suspension material inside, to prevent the material at the edge of the inner wall of the reaction chamber from not being fully stirred, the second motor drives the drive gear to rotate. Through gear transmission, the reaction chamber rotates. The baffle blocks the material inside, preventing it from being unable to rotate with the reaction chamber. This allows the material inside to rotate to the side or top and then mix with the overall material, thus ensuring the mixing effect. The hydraulic push rod drives the limit block to extend and retract, and through the connecting rod, the front of the reaction chamber rotates on the top of the mounting frame, and the rear of the reaction chamber rotates upward and downward. This allows the deposited material to flow into the overall material. Combined with the rotation of the reaction chamber and the stirring of the stirring rod, the deposited material inside can also be fully stirred, thus ensuring the mixing effect.

In order to better understand the technical means of this utility model and to implement it according to the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0026] Please refer to Figures 1-4 This utility model discloses a reaction vessel for preparing controlled-release dry suspension, comprising a reaction chamber 1 and an installation assembly. The reaction chamber 1 is the main body of the reaction vessel, used for preparing controlled-release dry suspension. The installation assembly includes a mounting frame 11 and a base 2, which are installation structures used for mounting other structures. A stirring rod 13 is rotatably installed inside the reaction chamber 1. A first motor 14 is installed at the rear of the reaction chamber 1, and the output end of the first motor 14 is connected to the stirring rod 13. That is, the first motor 14 drives the stirring rod 13 to rotate, thereby stirring and reacting the material for preparing the dry suspension inside. A feed inlet is provided at the top of the reaction chamber 1, and a discharge outlet is provided at the front bottom of the reaction chamber 1. Both the feed inlet and the discharge outlet are switched by solenoid valves, that is, the material is fed in and discharged through the feed inlet and the discharge outlet. All electrical equipment in the device is controlled by an external computer PLC intelligent controller. Equipment requiring external power is powered by an external power supply, which is a conventional technical means for those skilled in the art.

[0027] The reaction chamber 1 is rotatably mounted inside the mounting frame 11. Baffles 12 are arranged around the inner perimeter of the reaction chamber 1. A second motor 31, a servo motor, is located at the top rear of the mounting frame 11. A drive gear 32 is mounted on the output end of the second motor 31. An external gear 33 is located on the outer rear side of the reaction chamber 1. The drive gear 32 meshes with the external gear 33. When mixing the dry suspension material inside, to prevent the material at the edge of the inner wall of the reaction chamber 1 from being insufficiently stirred, the second motor 31 drives the drive gear 32 to rotate. Through gear transmission, the reaction chamber 1 rotates. The baffles 12 block the internal material, preventing it from being unable to rotate with the reaction chamber 1. This allows the internal material to rotate to the side or top before mixing with the overall material, thus ensuring the mixing effect.

[0028] The mounting frame 11 is rotatably mounted on the top of the support frame 21 on both sides of the front. The support frame 21 is set in front of the base 2, and the limiting rail 22 is set behind the base 2. The limiting rail 22 has a limiting block 23 slidingly set inside it. The top of the limiting block 23 is hinged to the connecting rod 3, which is hinged to the bottom of the rear of the mounting frame 11. The hydraulic push rod 24 is set behind the limiting rail 22. The telescopic end of the hydraulic push rod 24 is connected to the limiting block 23. When the front or rear of the reaction box 1 cannot be fully stirred, i.e., at the bottom of the existing mixing structure, the hydraulic push rod 24 drives the limiting block 23 to extend and retract. Then, the connecting rod 3 drives the transmission, so that the front of the reaction box 1 rotates on the top of the mounting frame 11, and the rear of the reaction box 1 rotates upward and downward, so that the deposited material flows into the overall material. With the rotation of the reaction box 1 and the stirring of the stirring rod 13, the deposited material inside can also be fully stirred, thus ensuring the mixing effect.

[0029] The working principle of this utility model is as follows: The first motor 14 drives the stirring rod 13 to rotate, thereby stirring and reacting the material for preparing the dry suspension inside. When mixing the material of the dry suspension inside, in order to prevent the material at the edge of the inner wall of the reaction chamber 1 from not being fully stirred, the second motor 31 drives the drive gear 32 to rotate. Through gear transmission, the reaction chamber 1 is rotated. The partition 12 blocks the material inside, preventing the material from not being able to rotate with the reaction chamber 1. This allows the material inside to rotate to the side or top and then mix with the overall material, thereby ensuring the mixing effect. The hydraulic push rod 24 drives the limiting block 23 to extend and retract, and through the connecting rod 3, the front of the reaction chamber 1 rotates on the top of the mounting frame 11, and the rear of the reaction chamber 1 rotates upward and downward, allowing the deposited material to flow into the overall material. Combined with the rotation of the reaction chamber 1 and the stirring of the stirring rod 13, the deposited material inside can also be fully stirred, thereby ensuring the mixing effect.
