Description

Technical Field

[0001] The utility model belongs to the technical field of medicine preparation equipment, in particular to a vacuum dryer for preparing injection cephalosporin products. Background Art

[0002] Cefuroxime is a general term for cephalosporin antibiotics, which is a bactericide that is usually used for anti-inflammatory effects on infections in various tissues and organs. During the preparation of injectable cephalosporin products, a vacuum dryer is required to dry the raw materials for the preparation of injectable cephalosporin products. Existing vacuum dryers are prone to uneven drying when in use, which reduces the drying effect of the raw materials for the preparation of injectable cephalosporin products located at the bottom, thereby reducing the drying effect of the vacuum dryer on the raw materials for the preparation of injectable cephalosporin products.

[0003] Example (authorization announcement number CN216481855U) A vacuum dryer for preparing injectable cephalosporin products. When the vacuum dryer for preparing injectable cephalosporin products is used, the vacuum pump and the vacuum solenoid valve are turned on by the controller. The vacuum pump first draws a vacuum through the vacuum pipe to the drying box. After the vacuum is drawn, the vacuum solenoid valve is closed, and then other equipment of the device is turned on. The feeding motor in the automatic feeding mechanism first drives the rotating shaft to rotate, and the rotating shaft drives the distributor to rotate evenly. The raw materials in the storage box are driven by the distributor to fall into the first conveyor at a uniform speed. The raw materials are conveyed along the first conveyor belt, the second conveyor belt and the third conveyor belt. During the conveying process, the heating plate is powered on to generate heat and transfers the heat to the raw materials through the conveyor belts, so that the raw materials are continuously dried during the conveying process. The dried raw materials fall from the third conveyor belt to the automatic material discharging mechanism and are uniformly transferred to the receiving box. However, the vacuum dryer does not take into account that the raw materials for the preparation of the injectable cephalosporin products located at the bottom are covered, resulting in uneven drying of the raw materials for the preparation of the injectable cephalosporin products, thereby reducing the drying effect of the vacuum dryer on the raw materials for the preparation of the injectable cephalosporin products.

The moving part of the linear motor 4 is fixedly connected with a moving plate 5, so that the moving part of the linear motor 4 can drive the moving plate 5 to move horizontally during the moving transmission process.

[0029] A plurality of telescopic inner rods 6 are welded to the bottom surface of the movable plate 5, and a sealing ring 7 is sleeved on the side of the telescopic inner rod 6 to facilitate the relative longitudinal movement of the telescopic inner rod 6 and the sealing ring 7.

The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0033] How it works

[0034] When using the vacuum dryer for preparing injectable cephalosporin products, the user introduces the raw materials for preparing injectable cephalosporin products into the vacuum dryer through the feed port 14, starts the conveyor 12 to realize the conveying effect, starts the linear motor 24, and the moving part of the linear motor 24 moves. Under the connecting action of the connecting rod 23, the movable rod 22 is relatively rotated and moved along the through grooves opened on the sides of the two movable plates 21, so that the baffle 19 is rotated to a specified angle, and the distance between the rubber plate 20 fixedly connected to the bottom surface of the baffle 19 and the conveyor 12 is controlled to realize the control of the drying thickness of the raw materials for preparing injectable cephalosporin products and prevent the raw materials from piling up, thereby improving the drying effect of the raw materials for preparing injectable cephalosporin products, and the external power supply device is connected to the electric heating plate 26 circuit to generate heat for the drying effect of the raw materials for preparing injectable cephalosporin products.

[0035] The feed port 14 and the discharge port 15 are closed by the electromagnetic valve, and the vacuum pump 25 is started to extract gas from the closed sealed space composed of the shell 1 and the bottom plate 13 to achieve its vacuum environment. The linear motor 4 is started, and the moving part of the linear motor 4 moves. During the transmission process, a plurality of rubber blocks 11 are driven to provide a toggling effect on the raw materials for preparing injectable cephalosporin products conveyed by the conveyor belt of the conveyor 12, so as to prevent the raw materials for preparing injectable cephalosporin products from being covered at the bottom, resulting in uneven drying, thereby improving the drying effect of the vacuum dryer on the raw materials for preparing injectable cephalosporin products. The telescopic inner rod 6 is arranged to move longitudinally relative to each other in the inner cavity of the telescopic outer rod 8. Under the elastic thrust of the booster spring 10, the contact strength between the rubber block 11 and the conveyor belt of the conveyor 12 is strengthened, thereby improving the toggling effect on the raw materials for preparing injectable cephalosporin products, and further improving the drying effect of the vacuum dryer on the raw materials for preparing injectable cephalosporin products.
