Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figure 1As shown, an automatic drying device for the preparation of benzylamine ammonium includes a drying chamber 1. A feed inlet 2 is located on the upper left side of the drying chamber, and a switch door plate is installed inside the feed inlet. The switch door plate can be horizontally inserted into the feed pipe. A belt conveyor structure 3 is installed inside the drying chamber, with the lower end of the feed pipe facing the belt conveyor structure. A guide structure 4 is located on the lower surface of the top wall of the drying chamber, with a gap between the guide structure and the belt conveyor structure. A distribution structure 5 is also located on the lower surface of the top wall of the drying chamber, with a gap between the distribution structure and the belt conveyor structure. The lower surface of the distribution structure is lower than the lower surface of the guide structure, and the distribution structure is located at the end of the guide structure away from the feed pipe. An electric heating element 6 is also installed inside the drying chamber. An outlet 7 is located on the right side of the lower surface of the drying chamber. The guide structure is a V-shaped plate, with the pointed end of the V-shaped plate facing the side where the feed pipe is located. The distribution structure includes multiple sets of spaced, parallel fixed plates arranged in a front-to-back direction. The electric heating element is installed between the upper and lower belts of the belt conveyor structure.

[0018] Furthermore, the belt of the belt conveyor structure has several fixing holes, and filter cloth is also fixed on the belt. A drive motor is located on the outside of the drying chamber, and the output shaft of the drive motor extends into the drying chamber and is connected to the belt conveyor structure through a transmission component.

[0019] Furthermore, the top wall of the drying chamber is equipped with an exhaust pipe 8, which is vertically arranged. A connecting pipe 9 is bent at the upper end of the exhaust pipe and passes through the upper part of the feed pipe. The portion of the connecting pipe inside the feed pipe serves as a heat exchange pipe. A branch pipe 10 is also provided before the connecting pipe enters the feed pipe. When some hot air is discharged, it can exchange heat with the material inside the feed pipe, raising the material temperature in advance and improving subsequent drying efficiency. Valves can be installed on the pipes.

[0020] The working principle of this utility model is as follows: the discharge end of the external storage tank is connected to the feed pipe. After feeding, benzyl chloride is placed on the belt, and the feed pipe is closed. The material passes through the guiding structure and the distribution structure. At the same time, the electric heating element heats the air to dry the benzyl chloride. When some gas is discharged from the box, the hot air comes out from the exhaust pipe and can exchange heat with the material in the feed pipe, thereby raising the material temperature in advance and improving the subsequent drying efficiency. After drying, the benzyl chloride falls into the discharge pipe of the discharge port, and then feeding is carried out again.

[0021] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
