Description

Technical Field

[0001] This utility model relates to the field of copper powder processing technology, and in particular to a copper powder dryer with a vibration and dispersion function. Background Technology

[0002] Copper powder is an important raw material for industrial production and can be used to manufacture chemical appliances, electrical appliances, building materials and other industrial equipment and appliances. Drying is an essential step in the production of copper powder.

[0003] Existing conventional methods use tunnel dryers to dry damp copper powder. However, damp copper powder is prone to clumping, and during drying, hot air cannot penetrate into the interior of the clumpy copper powder, preventing it from being dried completely. As a result, some copper powder discharged from the tunnel dryer is not fully dried, leading to poor drying effect. Therefore, this application provides a copper powder dryer with a vibration dispersing function to meet the requirements. Utility Model Content

[0004] The purpose of this application is to provide a copper powder dryer with a vibration and dispersion function to solve the technical problem in the prior art where hot air cannot enter the interior of the lumpy copper powder due to copper powder agglomeration, resulting in some copper powder not being completely dried during subsequent drying.

[0005] To achieve the above objectives, this application provides the following technical solution: a copper powder dryer with a vibration and dispersion function, comprising a dryer, wherein the dryer is provided with a chain conveyor belt and a plurality of drying chambers arranged in a straight line, and further comprising a vibration and dispersion unit for dispersing the copper powder agglomerated on the chain conveyor belt;

[0006] Each of the aforementioned drying chambers is equipped with a vibration dispersing unit.

[0007] In a preferred embodiment of this invention, the vibration unit includes a drive shaft and a driven shaft rotatably disposed in the drying chamber. One end of the drive shaft is fixedly connected to the output shaft of a drive motor provided on the outer wall of the drying chamber. Two sprockets are mounted on both the drive shaft and the driven shaft. The two sprockets on the drive shaft and the driven shaft and located on the same side are connected by chains. Several vibration components are mounted on the two chains.

[0008] The vibration component includes two connecting rods fixedly installed on the corresponding chain. The lower ends of the two connecting rods are fixedly connected to the upper end of the first horizontal plate. The lower end of the first horizontal plate is connected to the second horizontal plate through four elastic elements distributed at the four corners. The lower end of the second horizontal plate is densely covered with a number of insertion pins. A vibrator is provided at the upper axis of the second horizontal plate. The size of the second horizontal plate is adapted to the chain plate on the chain conveyor belt.

[0009] During operation, multiple vibrating components move along the motion path at the same speed as the running speed of the chain conveyor belt. When the vibrating component moves to the bottom and remains horizontal, it aligns with the corresponding chain plate.

[0010] In a preferred embodiment of this invention, the connecting rod, the first horizontal plate, the second horizontal plate, and the insertion pin are all made of thermally conductive metal material.

[0011] In a preferred embodiment of this invention, from left to right, the vibration intensity of the vibration unit in the previous drying chamber is higher than that in the next drying chamber.

[0012] In summary, the technical effects and advantages of this utility model are as follows:

[0013] This utility model has a reasonable structure and is equipped with multiple vibration and dispersing units to repeatedly disperse the clumps of copper powder, thereby improving the drying effect of the copper powder.

[0014] In this invention, from left to right, the vibration intensity of the dispersing unit in the previous drying chamber is higher than that in the next drying chamber. This avoids excessively high vibration frequency of the vibrator, which could lead to dust dispersion. This satisfies the dispersing of agglomerated copper powder while also reducing power consumption. Attached Figure Description

[0020] 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.

[0021] Example: Reference Figure 1 and Figure 2 The copper powder dryer shown includes a dryer 1, on which a chain conveyor belt 2 and multiple drying chambers 3 arranged in a straight line are provided. It also includes a vibration unit for dispersing the copper powder that has agglomerated on the chain conveyor belt 2.

[0022] By setting up a vibration and dispersion unit, the agglomerated copper powder is dispersed, thereby improving the drying effect of the copper powder.

[0023] Each of the multiple drying chambers 3 is equipped with a vibration dissipation unit;

[0024] Performing multiple copper powder shaking and dispersing operations can further improve the drying effect of copper powder.

[0025] As a preferred embodiment of this example, Figure 1-3 As shown, the vibration unit includes a drive shaft 4 and a driven shaft 5 rotatably disposed in the drying chamber 3. One end of the drive shaft 4 is fixedly connected to the output shaft of the drive motor provided on the outer wall of the drying chamber 3. Two sprockets 6 are installed on both the drive shaft 4 and the driven shaft 5. The two sprockets 6 on the drive shaft 4 and the driven shaft 5 and located on the same side are connected by a chain 7. Several vibration components are installed on the two chains 7.

[0026] The vibrating component includes two connecting rods 8 fixedly installed on the corresponding chain 7. The lower ends of the two connecting rods 8 are fixedly connected to the upper end of the first horizontal plate 9. The lower end of the first horizontal plate 9 is connected to the second horizontal plate 11 through four elastic elements 10 distributed at the four corners. The lower end of the second horizontal plate 11 is densely covered with a number of insertion pins 12. A vibrator 13 is provided at the upper end of the shaft of the second horizontal plate 11. The size of the second horizontal plate 11 is adapted to the chain plate on the chain conveyor belt 2.

[0027] During operation, multiple vibrating components move along the motion path at the same speed as the chain conveyor belt 2. When the vibrating component moves to the bottom and remains horizontal, it aligns with the corresponding chain plate.

[0028] During use, copper powder can be fed to the left side of the dryer 1 and spread evenly on the chain plate. The chain plate moves under the drive of the motor. At the same time, the vibrating component moves synchronously under the drive of the motor. During this movement, the insertion pin 12 on the vibrating component (the insertion pin 12 will vibrate under the action of the vibrator) will be inserted into the copper powder clumps on the corresponding chain plate. The vibrating insertion pin 12 will disperse the clumps of copper powder, so that the hot air can dry the copper powder inside the clumps of copper powder, thereby improving the drying effect of the dryer 1 on copper powder.

[0029] It should be noted that: First, multiple support sprockets 14 adapted to the chain 7 are provided to support the chain 7 and ensure its stable operation; Second, the drive motor is an adjustable speed motor, which is electrically connected to an external PLC controller; Third, an elastic element 10 is used to connect the first horizontal plate 10 and the second horizontal plate 11. The elastic element 10 has a certain degree of deformability, which can expand the vibration amplitude of the insertion needle 12 under the action of the vibrator, so that the vibration range of the insertion needle 12 is widened. The elastic element 10 can be a spring; Fourth, the vibrating component is located below the heating tube in the drying chamber.

[0030] As a preferred embodiment of this invention, not shown in the figure, the connecting rod 8, the first horizontal plate 9, the second horizontal plate 11, and the insertion pin 12 are all made of thermally conductive metal material.

[0031] This facilitates heat conduction to the copper powder and avoids significant obstruction of heat conduction by various components.

[0032] As a preferred embodiment of this example, Figure 1 As shown, from left to right, the vibration intensity of the vibration unit in the previous drying chamber 3 is higher than that in the next drying chamber 3.

[0033] As the drying time increases, the humidity of the copper powder decreases (i.e., the dryness increases), and the size of the agglomerated copper powder decreases (large agglomerated copper powder will be dispersed into smaller agglomerated copper powder, which can be dispersed with smaller vibrations). When the copper powder enters the next drying chamber 3 from the previous drying chamber 3, the humidity drops significantly. When setting it up, the vibration frequency of the vibrator 13 in the next drying chamber 3 must be lower than that of the vibrator 13 in the previous drying chamber 3. The purpose is to avoid the vibration frequency of the vibrator 13 being too high, which would cause dust to spread. This satisfies the agglomerated copper powder dispersion while also reducing power consumption.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
