Description

Technical Field

[0001] This application relates to the field of tea leaf debris treatment technology, and in particular to a tea leaf debris recycling device. Background Technology

[0002] Tea is a common commodity in our daily lives. During the production process and before packaging, tea needs to be sorted, mainly to separate tea leaves from tea fragments in order to improve the quality of the tea. For example, patent application number CN202220113472.8 discloses a tea air sorting device, which sorts tea leaves by blowing air with a fan, thereby achieving tea grading. It can also recycle tea leaves, but it requires a large space. Summary of the Invention

[0003] The purpose of this application is to provide a tea leaf debris recycling device to solve the above-mentioned technical problems.

[0004] The tea leaf debris recycling device provided in this application adopts the following technical solution: A tea leaf debris recycling device includes a negative pressure chamber, on which a blower is installed to generate negative pressure. A suction pipe is installed on one side of the negative pressure chamber, and an airflow baffle is installed inside the negative pressure chamber, dividing the negative pressure chamber into a feeding chamber and a debris chamber. The blower is installed directly above the debris chamber. An airflow channel is provided on the upper side of the airflow baffle and the top of the negative pressure chamber, which is used to allow tea leaf debris to enter the debris chamber. A discharge assembly is installed at the lower end of the negative pressure chamber, which is used to discharge the sorted tea leaves.

[0005] Optionally, the discharge assembly includes a distributing chamber installed at the lower end of the negative pressure chamber. A rotating shaft is rotatably mounted on the distributing chamber, and multiple sealing plates are mounted on the rotating shaft. A gap is left between the sealing plate and the inner wall of the distributing chamber on the side away from the rotating shaft. A distributing motor for driving the rotating shaft is installed on the distributing chamber. The upper side of the distributing chamber is connected to the negative pressure chamber, and a discharge port is provided on the side of the distributing chamber away from the negative pressure chamber.

[0006] Optionally, an airflow pipe is provided between the negative pressure chamber and the blower, and a powder buffer chamber is installed on the airflow pipe to reduce the amount of powder entering the blower.

[0007] Optionally, an electrostatic adsorption plate is installed inside the powder buffer chamber.

[0008] Optionally, a debris collection box can be detachably installed at the bottom of the debris bin.

[0009] Optionally, the debris collection box is equipped with a sealing plate that connects to the negative pressure chamber.

[0010] In summary, this application includes at least one of the following beneficial technical effects: 1. During the tea leaf debris recycling process, the bag containing the tea leaves is opened, the suction tube is inserted into the bag, and the blower is turned on to create negative pressure in the negative pressure chamber, which sucks the tea leaves into the negative pressure chamber, thereby reducing manual handling of the tea leaves and reducing the generation of tea leaf debris. 2. When the tea leaves enter the negative pressure chamber, the qualified tea leaves fall into the feeding hopper under their own weight, and the tea leaf debris follows the airflow through the airflow channel into the debris hopper. The qualified tea leaves are discharged from the discharge component, thus completing the removal of tea leaf debris and improving the quality of the tea. 3. Compared with existing technologies, this equipment generates airflow through negative pressure, and uses the difference in density and falling speed between tea debris and qualified tea to remove tea debris by means of the drop difference, without the need for multi-stage sorting and thus does not require too much space. 4. After the debris removal is completed, the tea leaves are fed back into the negative pressure chamber by adjusting the speed of the blower. This allows for the control of the lateral movement distance of tea leaves of different qualities following the airflow, thus sorting tea leaves of different grades. Attached Figure Description

Detailed Implementation

[0012] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail below.

[0013] Reference Figure 1 and Figure 2A tea leaf debris recycling device includes a negative pressure chamber 1, a blower 2 installed on the negative pressure chamber 1 to create negative pressure inside the chamber 1, a suction pipe 3 installed on one side of the negative pressure chamber 1, and an airflow baffle 4 installed inside the chamber 1 to divide the chamber 1 into a feeding chamber 5 and a debris chamber 6. The blower 2 is installed directly above the debris chamber 6. An airflow channel 7 is provided on the upper side of the airflow baffle 4 and the top of the negative pressure chamber 1 to allow tea leaf debris to enter the debris chamber 6. A discharge assembly 8 is installed at the lower end of the negative pressure chamber 1 to discharge the sorted tea leaves. During the tea leaf debris recycling process, the bag containing the tea leaves is opened, the suction pipe 3 is inserted into the bag, and the blower 2 is turned on to create negative pressure inside the negative pressure chamber 1, drawing the tea leaves into the chamber 1. This reduces manual handling of the tea leaves and the generation of tea leaf debris. When the tea leaves enter the negative pressure chamber 1, the qualified tea leaves fall into the feeding chamber 5 under their own gravity. The tea leaf debris follows the airflow through the airflow channel 7 and enters the debris chamber 5. The qualified tea leaves are discharged from the discharge component, thus completing the removal of tea leaf debris and improving the quality of the tea. Compared with existing technologies, this equipment generates airflow through negative pressure. It utilizes the difference in density and falling speed between tea fragments and qualified tea leaves to remove tea fragments by means of the drop difference. It does not require multi-stage sorting and therefore does not require too much space.

[0014] Reference Figure 2 The discharge assembly 8 includes a material distribution chamber 81 installed at the lower end of the negative pressure chamber 1. A rotating shaft 85 is rotatably mounted on the material distribution chamber 81. Multiple sealing plates 82 are mounted on the rotating shaft 85. A gap is left between the side of the sealing plate 82 away from the rotating shaft 85 and the inner wall of the material distribution chamber 81. A material distribution motor 83 that drives the rotating shaft 85 to rotate is installed on the material distribution chamber 81. The upper side of the material distribution chamber 81 is connected to the negative pressure chamber 1. A discharge port 84 is provided on the side of the material distribution chamber 81 away from the negative pressure chamber 1. When the tea leaves enter the feeding hopper 5, they fall between the closed plates 82 under their own weight. The distributing motor 83 drives the rotating shaft 85 to rotate, and the tea leaves are discharged from the discharge port 84. A tea collection bag is placed below the discharge port 84, which can directly package the tea leaves. A conveyor belt can also be installed below the discharge port 84 to transport the tea leaves after removing the debris to the tea bagging equipment for bagging. A gap is left between the side of the sealing plate 82 away from the rotating shaft 85 and the inner wall of the distributing chamber 81. During the process of the blower 2 creating negative pressure in the negative pressure chamber 1, a weak airflow passes through the gap, so that when the tea leaves approach the discharge component 8, there is an upward blowing force, thereby reducing the large impact force between the tea leaves and the discharge component 8 during the falling process, and further reducing the generation of tea leaf debris. The air intake through the gap is much smaller than that through the suction pipe 3, so as to ensure that the tea leaves can smoothly enter the negative pressure chamber 1 for sorting.

[0015] Reference Figure 2 An airflow pipe 11 is provided between the negative pressure chamber 1 and the blower 2. A powder buffer chamber 12 is installed on the airflow pipe 11. The powder buffer chamber 12 is used to reduce the amount of powder entering the blower 2. When tea leaves reach the powder buffer chamber 12 with the airflow, the airflow speed slows down and the tea leaves no longer continue to rise with the airflow, thus reducing the amount of tea leaves entering the blower 2.

[0016] Reference Figure 2 An electrostatic adsorption plate 13 is installed inside the powder buffer chamber 12. When tea powder enters the powder buffer chamber 12, the powder is adsorbed onto the electrostatic adsorption plate 13 under the action of the electrostatic adsorption plate 13, thereby preventing the powder from entering the blower 2.

[0017] Reference Figure 2 The bottom of the debris compartment 6 is detachably equipped with a debris collection box 9. After the debris is collected, the debris collection box 9 can be removed to clean the tea debris in time.

[0018] Reference Figure 2 and Figure 3 The debris collection box 9 is equipped with a sealing plate 91 that is connected to the negative pressure chamber 1 to improve the sealing performance of the equipment.
