Description

Technical Field

[0001] This utility model relates to the field of medicinal material processing technology, and in particular to a drying device for pharmaceutical intermediates. Background Technology

[0002] Pharmaceutical intermediates are chemical raw materials or chemical products used in the process of drug synthesis.

[0003] Reference to the utility model patent with authorization announcement number CN215676331U, a drying device for pharmaceutical intermediates is disclosed, including a device body and supporting legs. Two supporting legs are installed at the bottom of the device body, a feed inlet is installed at the top of the device body, a discharge door is hinged to the lower left side of the device body, a blower is arranged on the right side of the device body, a heating device is arranged above the blower, and an air supply pipe is connected to the heating device, the air supply pipe passing through one side of the device body.

[0004] The aforementioned patent requires the medicinal materials to be transported into the cylinder for stirring, heating and drying. The feeding and discharging processes during the drying process are time-consuming, which seriously affects the processing efficiency of the medicinal materials. In order to improve the drying efficiency of medicinal materials, we propose a drying device for pharmaceutical intermediates. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a drying device for pharmaceutical intermediates.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A drying device for pharmaceutical intermediates includes a support frame, a pharmaceutical material conveyor belt installed on the inner side of the support frame, a drying chamber mounted on the upper side of the support frame, a drying assembly mounted on the inner side of the drying chamber, a drive mechanism and an energizing mechanism respectively mounted on both sides of the drying assembly; the drying assembly includes several sets of rotating shafts, several heating and stirring blades fixedly mounted on the side walls of the rotating shafts, heating wires embedded in the inner sides of the heating and stirring blades, the two ends of the rotating shafts respectively passing through to the outside of the drying chamber, an end plate fixedly mounted on the left end of the rotating shaft, friction ridges evenly distributed and fixedly mounted on the outer wall of the end plate, and an electrode seat mounted on the right end of the rotating shaft.

[0008] Furthermore, the driving mechanism includes a slide groove, a slide sleeve is slidably installed inside the slide groove, a slide bar is slidably installed on the upper side of the slide sleeve, and a friction rubber plate is fixedly installed on the upper side of the slide bar, the friction rubber plate abutting against the lower side of the end plate.

[0009] By adopting the above technical solution, when the sliding sleeve is moved by the electric telescopic rod, the upper rubber friction plate can slide and rub against the end plates on the outer side of several rotating shafts, thereby synchronously driving several rotating shafts to rotate, and then driving the heating and stirring plate to rotate and stir in the drying box, so as to stir and dry the medicinal materials.

[0010] Furthermore, three synchronous electric telescopic rods are fixedly installed on the lower side of the slide, a side plate is fixedly installed at the end of the slide, and an electric telescopic rod is fixedly connected between the side plate and the slide sleeve.

[0011] Furthermore, several pressure sensors are fixedly installed on the bottom inner side of the sliding sleeve, and springs are fixedly installed on the upper side of the pressure sensors, with the upper end of the springs fixedly connected to the bottom of the sliding strip.

[0012] By adopting the above technical solution, the spring's rebound force causes the friction rubber plate on the upper slide bar to abut against the bottom of the end. The pressure sensor can sense the rebound force provided by the spring, and activate the telescopic rod to move the slide sleeve upward, thereby increasing the compression of the spring, increasing the abutment force on the upper friction rubber plate, and increasing the friction between the friction rubber plate and the end plate. At the same time, the pressure sensor can sense the abutment force provided by the upper friction rubber plate in real time, avoiding insufficient abutment force leading to insufficient friction, which would cause slippage between the friction rubber plate and the end plate.

[0013] Furthermore, the energizing mechanism includes a horizontal plate with several mounting holes. An insulating sleeve is fixedly installed inside the mounting holes, and a conductive electrode is slidably installed inside the insulating sleeve. The conductive electrode abuts against the electrode base.

[0014] Furthermore, an insulating spring is fixedly connected between the inner side of the insulating sleeve and the conductive electrode. A connecting metal wire is electrically connected to the inner end of the conductive electrode. An external electrode is connected to the connecting metal wire. The external electrode passes through to the outside of the insulating sleeve. A cable is connected in series between several of the external electrodes. A power plug is installed at the end of the cable.

[0015] By adopting the above technical solution, the current can be simultaneously guided to the conducting electrode after the cable is connected, and then transmitted to each rotating shaft through the conducting electrode to provide energy for the heating wire inside the stirring blade on the rotating shaft.

[0016] Furthermore, a mounting plate is fixedly installed on the upper side of the horizontal plate, and the mounting plate is screwed onto the outer wall of the drying oven.

[0017] Furthermore, the drying chamber has openings on both sides.

[0018] By adopting the above technical solution, the opening provides a passage for medicinal materials to enter the drying box.

[0019] Furthermore, a controller and a drive motor are fixedly installed on the side wall of the support frame. The output end of the drive motor rotates through to the inside of the pharmaceutical material conveyor belt, and the output end of the drive motor is fixedly connected to the drive shaft inside the pharmaceutical material conveyor belt.

[0020] Furthermore, a fan is fixedly installed on the upper side of the drying box, and a dustproof net is installed at the air outlet of the fan.

[0021] By adopting the above technical solution, during the drying process, the fan is started simultaneously to discharge the water vapor generated inside the drying chamber to the outside. The dustproof net is set to prevent dust from entering the drying chamber when the fan is not working.

[0022] Compared with related technologies, the drying equipment for pharmaceutical intermediates proposed in this utility model has the following beneficial effects:

[0023] In this utility model, a drying device for pharmaceutical intermediates is provided. A drying chamber is set on the conveyor belt of the pharmaceutical processing material. The drying chamber is equipped with several sets of rotating shafts. While the medicinal materials are being conveyed, the sets of rotating shafts are driven synchronously by a drive mechanism. When the rotating shafts rotate, they drive the heating and stirring plates on their outer walls to rotate. At the same time, the heating wires in the heating and stirring plates are activated, so that the surface of the heating and stirring plates can provide a heating effect. Thus, when the heating and stirring plates rotate, they can turn the medicine conveyed on the pharmaceutical processing material conveyor belt, heat and dry it, thereby improving its drying efficiency. The drying effect is completed simultaneously during the medicine conveying process. Its feeding and discharging are connected with its drying process, which greatly improves its processing efficiency and enhances its practicality. Attached Figure Description

By controlling the compression of the spring 58, the pressure provided by the sliding sleeve 55 to the upper slider 56 can be precisely controlled. The pressure provided by the spring 58 enables the friction rubber plate 59 to maintain a stable contact with the upper end plate 63. By moving the slider 56, the end plate 63 can be driven to rotate, which in turn drives the rotating shaft 61 to rotate, allowing several sets of rotating shafts 61 to rotate synchronously.

[0037] In this embodiment, the power supply mechanism 9 includes a horizontal plate 92, on which a plurality of mounting holes 93 are provided.
