Description

Technical Field

[0001] This utility model belongs to the field of drying equipment technology, and in particular to a belt vacuum drying equipment for drying phosphorus-based flame retardants. Background Technology

[0002] Flame retardant drying equipment is a specialized device used to remove moisture from flame retardant materials to produce granular or powdered flame retardant products. During production, flame retardants are usually present in a moist form and need to be dried to remove the moisture, ensuring the stability and effectiveness of the flame retardant. Existing drying equipment, in order to improve drying efficiency, installs stirring components and scrapers to prevent phosphorus-based flame retardants from sticking to the inside of the drying equipment, reducing waste and ensuring the processing efficiency of the equipment. Although this ensures the drying efficiency of the equipment to a certain extent, the flame retardant is transported and filled by a conveyor after drying, and the conveyor needs to be cleaned manually after use, making the cleaning operation of the equipment time-consuming and labor-intensive.

[0003] A search revealed Chinese patent document (authorization announcement number CN221975680U), which relates to the field of flame retardant drying. The invention discloses a flame retardant drying device, including a flame retardant drying cylinder. In this invention, an inner wall cleaning mechanism is used. When the flame retardant containing moisture enters the drying cylinder, the moisture molecules physically adsorb onto the surface-active substances on the inner wall of the drying device, forming a strong adsorption layer. The rotation of the drying cylinder causes a cleaning scraper to remove this adsorption layer, restoring the smoothness of the inner wall and reducing the retention of flame retardant on the cylinder wall, thereby improving drying efficiency. While this patent ensures a certain level of drying efficiency, the flame retardant is transported and filled via a conveyor after drying, requiring manual cleaning after use, making the cleaning process time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of this invention is to provide a belt vacuum drying device for drying phosphorus-based flame retardants, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a belt vacuum drying device for drying phosphorus-based flame retardants, comprising a mounting platform, a drying component for drying phosphorus-based flame retardants mounted at the top of the mounting platform, and an auxiliary component mounted at the bottom of the mounting platform. A belt conveyor is installed through the top of the mounting platform, and an auxiliary plate is fixedly connected to the top of the mounting platform. An open-type collection box is fixedly connected to the top of the mounting platform, and a wedge plate is fixedly connected to the inner bottom wall of the collection box. An installation roller is fixedly connected to the inner side of the collection box via two rotating shafts, and a stepper motor that provides power to the rotating shaft is mounted on the outer periphery of the collection box. A cleaning brush is adhered to the outer periphery of the installation roller. A fixed end of a linear motor is mounted on the side of the mounting platform, and a mounting plate is fixedly connected to the drive end of the linear motor. A drive shaft is rotatably connected to the side of the mounting plate, and an open-type linkage bucket is fixedly connected to one end of the drive shaft. A fixed end of a servo motor is mounted on the side of the mounting plate, and gears are mounted on the drive end of the servo motor and the outer periphery of the drive shaft, with the two gears meshing together.

[0006] Specifically, the drying assembly includes support plates fixedly connected to both sides of the mounting platform, a drying cylinder installed between the two support plates, and an air pump connected to the top of the drying cylinder.

[0007] Specifically, a heating element is installed on the side of the drying cylinder, and a stirring rod is rotatably connected to the inside of the drying cylinder.

[0008] Specifically, a stirring motor that provides power to the stirring rod is installed at the top of the drying cylinder, and a scraper is fixedly connected to the side of the stirring rod via a connecting rod.

[0009] Specifically, the auxiliary components include a mounting box installed at the bottom of the mounting platform, a lead screw rotatably connected to the inside of the mounting box, and a drive motor installed on the side of the mounting box to provide power to the lead screw.

[0010] Specifically, the lead screw has two moving blocks connected to its outer circumference by threads, and one end of the moving block is fixedly connected to an adjusting plate, and the side of the adjusting plate is fixedly connected to a feeding claw.

[0011] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0012] This belt vacuum drying equipment for phosphorus-based flame retardants benefits from the design of stepper motors, drying components, and auxiliary components. When the belt conveyor transports the phosphorus-based flame retardant, the stepper motor drives the cleaning brush on the outer periphery of the mounting roller to rotate, thereby cleaning the flame retardant adhering to the belt conveyor. The cleaned flame retardant falls onto the wedge plate inside the collection box and finally slides into the linkage hopper. The linear motor is activated to drive the linkage hopper to rise, and the servo motor is activated to drive the linkage hopper to rotate, thereby pouring the cleaned flame retardant onto the upper belt. Compared with the cleaning method of existing devices, this device can achieve an automatic cleaning effect, making the cleaning operation more time-saving and labor-saving. The design of the drying component is designed to dry the flame retardant and prevent it from adhering to the inner lining of the drying cylinder. The design of the auxiliary components assists the operator in the filling operation, greatly increasing the practicality of the device.

[0013] This belt vacuum drying equipment for drying phosphorus-based flame retardants can automatically clean the belt conveyor, making the cleaning operation of the device more time-saving and labor-saving. Attached Figure Description

[0029] Working principle

[0030] In this belt vacuum drying equipment for phosphorus-based flame retardants, the phosphorus-based flame retardant to be dried is added into the drying cylinder 33 through the feed inlet. The heating component 32 is started for drying. The stirring motor 35 is started to drive the stirring rod 36 and scraper 37 to rotate.

The stepper motor 12 is started to drive the cleaning brush 13 on the outer periphery of the mounting roller 11 to rotate, thereby cleaning the flame retardant adhering to the belt conveyor 2. The cleaned flame retardant falls onto the wedge plate 10 inside the collection box 6 and finally slides into the linkage hopper 8. The linear motor 7 is started to drive the linkage hopper 8 to rise, and the servo motor 16 is started to drive the linkage hopper 8 to rotate, thereby pouring the cleaned flame retardant onto the belt at the upper end for conveying.
