Description

Technical Field

[0001] This utility model relates to the technical field of vacuum drying oven devices, and more specifically to a vacuum drying oven device for the production of domiphen. Background Technology

[0002] A vacuum drying oven is a device that lowers the boiling point of materials through a negative pressure environment to achieve low-temperature and efficient drying. It is widely used in the pharmaceutical, chemical, food, and electronics industries for processing heat-sensitive materials. Traditional vacuum drying ovens mainly consist of a heating system, a vacuum pump unit, a chamber, and a control system. They utilize heat conduction or radiation heating in conjunction with a vacuum environment to accelerate moisture evaporation. However, they have limitations such as poor temperature uniformity, high energy consumption, and unstable drying efficiency.

[0003] In recent years, with the increasing demands of technological processes, modern vacuum drying ovens have adopted PID intelligent temperature control technology and multi-stage vacuum regulation to achieve more precise temperature and pressure control. Some equipment integrates online moisture detection and automatic pressure relief functions, optimizing the determination of the drying endpoint. In addition, the application of new structural designs (such as multi-layer tray rotation systems) and high-efficiency energy-saving vacuum pumps has further improved drying uniformity and energy efficiency.

[0004] Insufficiency of existing technology: Existing equipment requires a lot of energy to create a vacuum state inside the equipment, resulting in high energy consumption. In addition, existing equipment does not heat materials evenly during processing, making it difficult to ensure uniform heating of materials. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a vacuum drying oven device for the production of domiphen, so as to solve the problems existing in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vacuum drying oven device for the production of domiphen, comprising a drying cylinder assembly, a lifting assembly fixedly connected to the top of the drying cylinder assembly, a heating and drying assembly installed at the bottom of the drying cylinder assembly, the drying cylinder assembly comprising a drying cylinder body, an arc-shaped support leg fixedly connected to the bottom of the drying cylinder body, a positioning hole provided in the middle of the bottom of the drying cylinder body, and a positioning groove provided in the bottom of the inner side of the drying cylinder body.

[0007] Furthermore, the lifting assembly includes an L-shaped fixing plate, a hydraulic cylinder is fixedly connected to the top of the L-shaped fixing plate, a hydraulic rod is fixedly connected to the bottom of the hydraulic cylinder, a lifting plate is fixedly connected to the bottom of the hydraulic rod, a material inlet is installed on the top of the lifting plate, and a solenoid valve is fixedly connected to the outside of the material inlet.

[0008] Furthermore, the heating and drying assembly includes a servo motor, the output shaft of which is equipped with a rotating circular plate. A heating ring is installed at the bottom of the rotating circular plate, and a heating connecting rod is fixedly connected between the heating rings. A transmission rod is installed on the outermost side of the heating ring, and a heating control power supply is fixedly connected to the side of the transmission rod away from the heating ring.

[0009] Furthermore, the diameter of the lifting plate and the inner diameter of the drying cylinder body are matched, and the diameter of the positioning hole and the diameter of the servo motor output shaft are matched with a clearance.

[0010] Furthermore, the diameter difference between any two adjacent heating rings is the same, the centers of the heating rings are in the same position, and the dimensions of the heating rings, heating connecting rods, and transmission rods are matched with the dimensions of the positioning grooves.

[0011] Furthermore, there is a clearance fit between the diameter of the rotating circular plate and the inner diameter of the drying cylinder body, and a clearance fit between the inner diameter of the heating control power supply and the outer diameter of the drying cylinder body.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. In the processing of this utility model, the material to be heated is injected into the inner side of the drying cylinder body through the inlet, so that the material is located at the top of the rotating disc. Then, the hydraulic cylinder works to extend the hydraulic rod, which in turn pushes the lifting plate, the inlet, and the solenoid valve to descend, so that the bottom of the lifting plate is in contact with the material located at the top of the rotating disc. Then, the solenoid valve is closed, and the hydraulic cylinder works to retract the hydraulic rod, which drives the lifting plate to rise. This creates a vacuum state in the space between the drying cylinder body, the lifting plate, and the rotating disc, so that the equipment does not need to spend a lot of energy to create a vacuum, thus reducing the energy consumption of the equipment.

[0014] 2. In the heating and drying process, this utility model uses a heating control power supply to heat the transmission rod, heating ring, and heating connecting rod to heat the rotating disc, causing the temperature of the rotating disc to rise. At the same time, the servo motor drives the rotating disc to rotate, thus ensuring that the rotating disc is evenly heated by the transmission rod, heating ring, and heating connecting rod, guaranteeing uniform drying of the material and ensuring the drying efficiency of the equipment.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The vacuum drying oven device for the production of domiphen involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Reference Figures 1 to 5 This utility model provides a vacuum drying oven device for the production of domiphen, including a drying cylinder assembly 1, a lifting assembly 2 fixedly connected to the top of the drying cylinder assembly 1, a heating and drying assembly 3 installed at the bottom of the drying cylinder assembly 1, the drying cylinder assembly 1 including a drying cylinder body 101, an arc-shaped support leg 102 fixedly connected to the bottom of the drying cylinder body 101, a positioning hole 103 opened in the middle of the bottom of the drying cylinder body 101, and a positioning groove 104 opened in the bottom of the inner side of the drying cylinder body 101.

[0023] In a preferred embodiment, the lifting assembly 2 includes an L-shaped fixed plate 201. A hydraulic cylinder 202 is fixedly connected to the top of the L-shaped fixed plate 201, a hydraulic rod 203 is fixedly connected to the bottom of the hydraulic cylinder 202, and a lifting plate 204 is fixedly connected to the bottom of the hydraulic rod 203. A material inlet 205 is installed on the top of the lifting plate 204, and a solenoid valve 206 is fixedly connected to the outside of the material inlet 205. During processing, the material to be heated is injected into the inner side of the drying cylinder body 101 through the material inlet 205, so that the material is located on the top of the rotating circular plate 302, and then the hydraulic cylinder 202... The operation causes the hydraulic rod 203 to extend, which in turn pushes the lifting plate 204, the feeding port 205, and the solenoid valve 206 to descend, so that the bottom of the lifting plate 204 is in contact with the material located on the top of the rotating disc 302. Then, the solenoid valve 206 is closed, and the hydraulic cylinder 202 works to cause the hydraulic rod 203 to retract, which drives the lifting plate 204 to rise. This creates a vacuum in the space between the drying cylinder body 101, the lifting plate 204, and the rotating disc 302, so that the equipment does not need to spend a lot of energy to evacuate the equipment, thus reducing the energy used by the equipment and effectively reducing the energy consumption of the equipment.

[0024] In a preferred embodiment, the heating and drying assembly 3 includes a servo motor 301. A rotating circular plate 302 is mounted on the output shaft of the servo motor 301. A heating ring 303 is mounted on the bottom of the rotating circular plate 302. A heating connecting rod 304 is fixedly connected between the heating rings 303. A transmission rod 305 is mounted on the outermost side of the heating rings 303. A heating control power supply 306 is fixedly connected to the side of the transmission rod 305 away from the heating rings 303. During the heating and drying process, the heating control power supply 306 causes the transmission rod 305, the heating rings 303, and the heating connecting rod 304 to heat the rotating circular plate 302, causing the temperature of the rotating circular plate 302 to rise. At the same time, the servo motor 301 drives the rotating circular plate 302 to rotate, thereby ensuring that the rotating circular plate 302 is uniformly heated by the transmission rod 305, the heating rings 303, and the heating connecting rod 304, ensuring uniform drying of the material and guaranteeing the drying efficiency of the equipment.

[0025] In a preferred embodiment, the diameter of the lifting plate 204 and the inner diameter of the drying cylinder body 101 are matched, and the diameter of the positioning hole 103 and the diameter of the output shaft of the servo motor 301 are matched with a clearance.

[0026] In a preferred embodiment, the diameter difference between two adjacent heating rings 303 is the same, the centers of the heating rings 303 are in the same position, and the dimensions of the heating rings 303, the heating connecting rods 304 and the transmission rods 305 are matched with the dimensions of the positioning grooves 104.

[0027] In a preferred embodiment, there is a clearance fit between the diameter of the rotating disc 302 and the inner diameter of the drying cylinder body 101, and a clearance fit between the inner diameter of the heating control power supply 306 and the outer diameter of the drying cylinder body 101.

[0028] The working principle of this utility model is as follows: During the processing, the material to be heated is injected into the inner side of the drying cylinder body 101 through the injection port 205, so that the material is located at the top of the rotating circular plate 302. Then, the hydraulic cylinder 202 works to extend the hydraulic rod 203, which in turn pushes the lifting plate 204, the injection port 205 and the solenoid valve 206 to descend, so that the bottom of the lifting plate 204 is in contact with the material located at the top of the rotating circular plate 302. Then, the solenoid valve 206 is closed, and the hydraulic cylinder 202 works to retract the hydraulic rod 203, which drives the lifting plate 204 to rise. This makes the space between the drying cylinder body 101, the lifting plate 204 and the rotating circular plate 302 a vacuum state, so that the equipment does not need to spend a lot of energy to evacuate the equipment, thus reducing the energy used by the equipment and effectively reducing the energy consumption of the equipment.

[0029] During the heating and drying process, the heating control power supply 306 operates to heat the transmission rod 305, heating ring 303, and heating connecting rod 304, thereby heating the rotating circular plate 302 and causing its temperature to rise. At the same time, the servo motor 301 operates to drive the rotating circular plate 302 to rotate, which in turn ensures that the rotating circular plate 302 is heated evenly by the transmission rod 305, heating ring 303, and heating connecting rod 304, thus ensuring uniform drying of the material and guaranteeing the drying efficiency of the equipment.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
