Abstract
Description
Technical Field
[0001] This utility model relates to the field of tea processing technology, and in particular to a negative pressure adsorption type tea dust separator. Background Technology
[0002] Tea leaves refer to the leaves and buds of the tea plant, also known as tea, jia, ming, and chuan. It generally refers to the leaves of the evergreen shrub tea plant, which can be used to make tea, as well as the beverage made from these leaves. Tea is one of the most popular drinks among people in Southeast Asian countries, especially the Chinese. During the processing of tea, the roasted tea leaves will contain some tea dust, which needs to be separated from the tea leaves. The current method is to manually hold a winnowing basket or silkworm tray and toss the roasted tea leaves in the basket or tray to separate the tea leaves from the tea dust.
[0003] Existing technologies for separating tea leaves typically rely on manual separation or the use of sieves. Manual sieving is time-consuming and inefficient, while sieve separation may result in incomplete separation of tea leaves, requiring repeated sieving, which negatively impacts the tea leaf separation process. To address the shortcomings of existing technologies, we propose a negative pressure adsorption type tea leaf separator. Utility Model Content
[0004] The main purpose of this invention is to provide a negative pressure adsorption type tea leaf dust separator, which can effectively solve the problems in the background technology.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A negative pressure adsorption type tea dust separator includes a conveyor box with a discharge port at its upper end. A conveyor belt is located at the bottom of the conveyor box. A falling channel is located at the lower front side of the conveyor box. An opening is located at the upper end of the falling channel at the bottom front side of the conveyor box. The upper opening of the falling channel is located below the front end of the conveyor belt. A receiving box is located below the falling channel. Three sets of air inlet pipes are located on the rear side wall of the falling channel. A connecting pipe is located on the front side wall of the falling channel. A negative pressure pipe is located at the front end of the connecting pipe. An air extraction pipe is located at the upper end of the negative pressure pipe. A dust collection box is located at the lower end of the negative pressure pipe, and the interior of the dust collection box is connected to the lower end of the negative pressure pipe.
[0007] Preferably, a connecting frame is provided between the upper outer wall of the falling channel and the lower front end of the material receiving box, and a connecting cover is provided between the lower outer wall of the falling channel and the upper outer wall of the receiving box. The two ends of the connecting cover are detachably connected to the lower end of the falling channel and the upper end of the receiving box, respectively.
[0008] Preferably, a filter screen is installed inside the upper end of the negative pressure pipe, an exhaust fan is provided at the front end of the air extraction pipe, and a drawer is movably connected inside the waste bin.
[0009] Preferably, a set of transmission rollers is provided at each of the two ends of the conveyor belt, and the ends of the two sets of transmission rollers are rotatably connected to the inner wall of the material box. A set of motors is installed on the outer wall of the material box, and the motors are connected to the ends of the set of transmission rollers.
[0010] Preferably, the lower end of the discharge port extends into the interior of the material transfer box, and a material distribution tray is provided above the conveyor belt.
[0011] Preferably, the lower end of the material transfer box is provided with four sets of support legs, and the lower end of the crushing box is provided with a support frame.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. In this utility model, the falling channel, negative pressure pipe, and exhaust pipe can utilize the principle of negative pressure adsorption to separate tea dust from the tea leaves. As the tea leaves fall inside the falling channel, the exhaust pipe exhausts air outward, creating a negative pressure inside the negative pressure pipe. The lighter tea dust inside the falling channel is adsorbed into the negative pressure pipe due to the pressure difference. After adsorption stops, it falls into the dust collection box and is collected. The tea leaves, due to their weight, fall into the receiving box. In this way, the tea dust can be efficiently separated from the tea leaves using negative pressure.
[0014] 2. In this utility model, the material distribution tray can disperse the tea leaves added inside the feeding port, so that the tea leaves can be evenly distributed when they fall on the upper end of the conveyor belt. When the conveyor belt transports the tea leaves to the upper end of the falling channel, they can be better dispersed. When the tea leaves fall freely inside the falling channel, the tea leaf fragments will also be better adsorbed and separated, resulting in a better separation effect. Attached Figure Description

The upper opening of the falling channel 3 is located below the front end of the conveyor belt 19. The conveyor belt 19 transports the tea leaves to the upper end of the falling channel 3. The tea leaves fall inside the falling channel 3. A connecting frame 11 is provided between the upper outer wall of the falling channel 3 and the lower front end of the material box 1. 1 is used to install and fix the upper end of the falling channel 3 to the lower end of the material box 1. A receiving box 4 is set below the falling channel 3. Tea leaves fall from the inside of the falling channel 3 into the inside of the receiving box 4. A connecting cover 13 is set between the lower outer wall of the falling channel 3 and the upper outer wall of the receiving box 4. The two ends of the connecting cover 13 are detachably connected to the lower end of the falling channel 3 and the upper end of the receiving box 4, respectively. The connecting cover 13 is used to connect the receiving box 4 and the falling channel 3 to prevent the tea leaves from spilling.
[0022] like Figures 1-4As shown, three sets of air inlet pipes 12 are provided on the rear side wall of the falling channel 3. The air inlet pipes 12 are used for air intake. A connecting pipe 14 is provided on the front side wall of the falling channel 3. A negative pressure pipe 5 is provided at the front end of the connecting pipe 14. The connecting pipe 14 is used to connect the falling channel 3 and the negative pressure pipe 5. An air extraction pipe 6 is provided at the upper end of the negative pressure pipe 5.
