Description

Technical Field

[0001] This utility model relates to the field of powder processing technology, and in particular to a device for powder post-processing. Background Technology

[0002] Drying and grinding are key processes in powder post-processing. Drying is used to remove moisture or other volatiles from the powder to ensure the dryness of the powder, while grinding uses mechanical force to refine the powder particles and adjust the particle size distribution. The combination of the two can optimize the powder's flowability, dispersibility and other performance properties, and adapt to the application needs of chemical, building materials and pharmaceutical fields.

[0003] In the drying stage of powder post-processing, most hot air pipes are currently fixed, which means that the hot air can only cover a local area and it is difficult to achieve full and uniform contact with the accumulated powder, affecting the drying quality, prolonging the drying time, and thus reducing the processing efficiency. Therefore, we propose a device for powder post-processing. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides a device for powder post-processing.

[0005] This utility model is achieved using the following technical solution: a device for powder post-processing, comprising a grinding box, a drying cylinder fixedly connected to the top of the grinding box, a feed pipe and an exhaust pipe connected to the top of the drying cylinder, a hot air blower fixedly connected to the top of the drying cylinder, an air outlet pipe connected to the air outlet end of the hot air blower, a drive assembly provided in the middle of the drying cylinder, a grinding assembly provided inside the grinding box, a collection box slidably connected to the inner wall of the grinding box, a discharge pipe connected to the bottom of the drying cylinder, and a solenoid valve fixedly installed at the bottom of the discharge pipe; The drive assembly includes a first motor, the output end of which is fixedly connected to a main pulley. A belt is driven to the surface of the main pulley, and a secondary pulley is driven to the inner wall of the belt. A hollow tube is fixedly connected to the inner wall of the secondary pulley. A rotating sleeve is rotatably connected to the top of the hollow tube. Several stirring blades are fixedly connected to the surface of the hollow tube. An air outlet pipe is connected to the inner wall of the hollow tube, and several air outlet holes are opened on the inner wall of the air outlet pipe.

[0006] Through the above technical solution, the first motor drives the main pulley to rotate, and the belt drives the auxiliary pulley to rotate, causing the hollow tube to rotate. This, in turn, drives the stirring blades to rotate and stir the powder, preventing powder accumulation. The air outlet pipe, which is connected to the hollow tube, rotates together, and hot air is blown out from different positions through several air outlet holes on the air outlet pipe, achieving full contact between the hot air and the powder, thereby improving the drying effect and efficiency.

[0007] As a further improvement to the above solution, the bottom of the first motor is fixedly connected to the top of the drying cylinder, the end of the air outlet pipe away from the hot air blower is fixedly connected to the inner wall of the rotating sleeve, and the air outlet pipe is connected to the hollow pipe.

[0008] With the above technical solution, since the rotating sleeve is rotatably connected to the hollow tube, the rotation of the hollow tube is prevented from causing the air outlet tube to rotate.

[0009] As a further improvement to the above solution, the surface of the hollow tube is rotatably connected to the inner wall of the drying cylinder, and the number of air outlet pipes is set to several, which are arranged in a circle around the hollow tube.

[0010] The above technical solution allows for convenient blowing of hot air to different locations inside the drying cylinder through several air outlet pipes, ensuring full contact between the hot air and the powder and avoiding localized dampness or excessive dryness.

[0011] As a further improvement to the above solution, the grinding assembly includes two grinding rollers, each with a rotating rod fixedly connected to its inner wall. A gear is fixedly connected to the surface of the rotating rod, and a protective cover is rotatably connected to the surface of the rotating rod. A second motor is fixedly connected to one end of the protective cover.

[0012] Through the above technical solution, the second motor drives one of the rotating rods to rotate. Through the meshing of two gears, the two rotating rods rotate, causing the two grinding rollers to rotate in opposite directions. The powder falling between the two grinding rollers is squeezed and ground, effectively breaking up the clumps formed after drying.

[0013] As a further improvement to the above solution, the surface of the rotating rod is rotatably connected to the inner wall of the grinding box, and the two gears mesh with each other.

[0014] As a further improvement to the above solution, the front end of the protective cover is fixedly connected to the rear end of the grinding box, and the output end of the second motor is fixedly connected to one end of the rotating rod.

[0015] The above technical solution protects the gears with a protective cover, preventing accidental injury to workers during operation and avoiding the impact of powder on the gears.

[0016] As a further improvement to the above solution, the lower end of the discharge pipe extends into the interior of the grinding box, and the discharge pipe is located above the grinding roller.

[0017] The above technical solution allows the dried powder to be discharged between two grinding rollers through a discharge pipe, facilitating subsequent grinding.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention features a drive assembly. Specifically, a first motor drives the main pulley to rotate, which in turn drives the auxiliary pulley to rotate via the belt. This causes the hollow tube to rotate, which in turn drives the stirring blades to stir the powder, preventing powder accumulation. The air outlet pipe, which is connected to the hollow tube, rotates together, and hot air is blown out from different positions through several air outlets on the air outlet pipe, achieving full contact between the hot air and the powder, thereby improving the drying effect and efficiency.

[0019] This invention integrates drying and grinding functions by setting up a driving component and a grinding component. After drying, the clumps are directly broken up by the grinding component, eliminating the need for additional transfer and crushing steps, thus simplifying the processing flow and improving processing efficiency.

The drive assembly 7 includes a first motor 701. A main pulley 702 is fixedly connected to the output end of the first motor 701. A belt 703 is driven through the surface of the main pulley 702. A secondary pulley 704 is driven through the inner wall of the belt 703. A hollow tube 705 is fixedly connected to the inner wall of the secondary pulley 704. A rotating sleeve 706 is rotatably connected to the top of the hollow tube 705. Several stirring blades 707 are fixedly connected to the surface of the hollow tube 705. An air outlet pipe 708 communicates with the inner wall of the hollow tube 705. Several air outlet holes 709 are opened on the inner wall of the air outlet pipe 708. The hot air blower 5 is then started. The hot air blower 5 sends hot air into the hollow tube 705 through the air outlet pipe 6, starts the first motor 701, drives the main pulley 702 to rotate, and drives the auxiliary pulley 704 to rotate through the transmission action of the belt 703, causing the hollow tube 705 to rotate, which drives the stirring blades 707 to rotate to stir the powder and prevent the powder from accumulating. The air outlet pipe 708 connected to the hollow tube 705 rotates together, and blows hot air out from different positions through several air outlet holes 709 on the air outlet pipe 708, so as to achieve full contact between the hot air and the powder, thereby improving the drying effect and efficiency.

[0024] The bottom of the first motor 701 is fixedly connected to the top of the drying cylinder 2. The end of the air outlet pipe 6 away from the hot air blower 5 is fixedly connected to the inner wall of the rotating sleeve 706. The air outlet pipe 6 is connected to the hollow tube 705. Because the air outlet pipe 6 is connected to the hollow tube 705, hot air can be sent into the interior of the hollow tube 705 and blown out through the air outlet pipe 707.

[0025] The surface of the hollow tube 705 is rotatably connected to the inner wall of the drying cylinder 2. Several air outlet pipes 708 are provided, and the several air outlet pipes 708 are arranged in a circle around the hollow tube 705.

[0026] The grinding assembly 8 includes two grinding rollers 801. A rotating rod 802 is fixedly connected to the inner wall of each grinding roller 801. A gear 803 is fixedly connected to the surface of the rotating rod 802. A protective cover 804 is rotatably connected to the surface of the rotating rod 802. A second motor 805 is fixedly connected to one end of the protective cover 804. When the second motor 805 is started, it drives one of the rotating rods 802 to rotate. Through the meshing action of the two gears 803, the two rotating rods 802 rotate, causing the two grinding rollers 801 to rotate in opposite directions. The powder falling between the two grinding rollers 801 is squeezed and ground, effectively breaking up the clumps formed after drying.

[0027] The surface of the rotating rod 802 is rotatably connected to the inner wall of the grinding box 1, and the two gears 803 mesh with each other.

[0028] The front end of the protective cover 804 is fixedly connected to the rear end of the grinding box 1, and the output end of the second motor 805 is fixedly connected to one end of the rotating rod 802.

[0030] The implementation principle of the device for powder post-processing in this embodiment is as follows: During use, the feed pipe 3 to be processed is inserted into the drying cylinder 2. The hot air blower 5 is started, and hot air is sent into the hollow tube 705 through the air outlet pipe 6. The first motor 701 is started, driving the main pulley 702 to rotate. Through the transmission action of the belt 703, the auxiliary pulley 704 rotates, causing the hollow tube 705 to rotate. This causes the stirring blades 707 to rotate, stirring the powder and preventing powder accumulation. The air outlet pipe 708, connected to the hollow tube 705, rotates together, blowing hot air out from different positions through several air outlet holes 709 on the air outlet pipe 708, achieving full contact between the hot air and the powder, thereby improving the drying effect and efficiency. The moisture generated during the drying process is discharged through the exhaust pipe 4. After the powder is dried, the solenoid valve 11 is opened, allowing the powder inside the drying cylinder 2 to enter the grinding chamber 1 through the discharge pipe 10. At this time, the second motor 805 is started. The second motor 805 drives one of the rotating rods 802 to rotate. Through the meshing of two gears 803, the two rotating rods 802 rotate, which drives the two grinding rollers 801 to rotate in opposite directions. The powder falling between the two grinding rollers 801 is squeezed and ground, effectively breaking up the clumps formed after drying. The ground powder falls into the inside of the collection box 9 and is collected by the collection box 9.
