Description

Technical Field

[0001] This invention relates to the field of powder collection equipment technology, and in particular to a tea powder collection device for matcha processing. Background Technology

[0002] Matcha powder is made through ultra-fine grinding, resulting in fine particle size, large specific surface area, and strong electrostatic adsorption properties, making it easy to adhere to the inner wall of equipment. At the same time, the powder is thin and light, making it easy to spread dust when disturbed by airflow. It is also prone to agglomeration and clumping under pressure during storage and transportation. Furthermore, as a food raw material, matcha powder has strict requirements for production cleanliness and material recovery rate. The tea powder collection device is a core supporting equipment in the deep processing of matcha. It is mainly responsible for the sealed reception of the ground tea powder, completing the work of impurity filtration, powder collection, and air-powder separation. Its performance directly determines the material utilization rate, production cleanliness, and finished product appearance of the entire production line. It is an indispensable key equipment to ensure the large-scale and standardized processing of matcha.

[0003] Traditional matcha processing tea powder collection devices often use rigid feed filters, which are prone to clogging the mesh with powder. They lack automatic cleaning mechanisms, requiring frequent shutdowns for manual cleaning and interrupting production. Furthermore, they rely solely on a single negative pressure airflow to transport the powder without an internal air supply and guidance structure, resulting in the powder drifting haphazardly within the chamber. The bottom discharge lacks a dynamic shearing and crushing structure, and the agglomerated powder is directly collected, affecting subsequent processing. Summary of the Invention

[0004] To overcome the above shortcomings, the present invention provides a tea powder collection device for matcha processing, which aims to improve the problems in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a tea powder collection device for matcha processing, comprising an aggregating mechanism, wherein a collection mechanism is provided at the bottom of the aggregating mechanism, the aggregating mechanism includes a vibrating shell component, a filtering component is installed at the top of the vibrating shell component, a wall scraping component is provided inside the vibrating shell component, and the inner wall of the vibrating shell component is connected to the top of the collection mechanism. The wall scraping component includes a main shaft, with an upper scraper and a lower scraper fixedly connected to the outer surface of the main shaft. Scraping strips are movably connected to the outer surfaces of the upper and lower scrapers, and a disturbance rod is fixedly connected to the top of the main shaft.

[0006] As a further description of the above technical solution: The vibrating shell component includes a spliced ​​spherical shell, the inner wall of which is movably connected to a dustproof spherical shell, the inner wall of which is fixedly connected to a baffle ring, and the inner wall of which is fixedly connected to an air filter.

[0007] As a further description of the above technical solution: The filtration component includes a feed pipe, an mounting frame is fixedly connected to the inner wall of the feed pipe, a filter screen is movably connected to the inner wall of the mounting frame, and the outer surface of the feed pipe is fixed to the inner wall of the dustproof shell.

[0008] As a further description of the above technical solution: The outer surface of the scraper bar slides against the inner wall of the dustproof ball shell, the outer surface of the disturbance rod slides against the outer surface of the filter screen, and the upper scraper is disposed on top of the lower scraper.

[0009] As a further description of the above technical solution: There are three upper and lower scrapers, and each upper and lower scraper forms a scraping unit. The upper and lower scrapers in each scraping unit are distributed on the surface of the main shaft at a 180° offset from the axis of the main shaft, and the upper and lower scrapers are inclined at a 20° angle to the axis of the main shaft.

[0010] As a further description of the above technical solution: The collection mechanism includes a storage component, the inside of which is equipped with an anti-caking component, and the surface of the storage component is in contact with the bottom of the vibrating shell component.

[0011] As a further description of the above technical solution: The storage component includes a collection box, an air-powder separator is fixedly connected to the inner wall of the collection box, a negative pressure pipe is fixedly connected to the surface of the collection box, the air-powder separator is located at the end of the negative pressure pipe, and a discharge pipe is movably connected to the top of the collection box, the outer surface of the discharge pipe is fixed to the inner wall of the dustproof shell.

[0012] As a further description of the above technical solution: The anti-caking component includes a driving member, a frame plate fixedly connected to the outer surface of the driving member, the end of the frame plate being fixed to the inner wall of the discharge pipe, a drive shaft fixedly connected to the end of the driving member, a lower perforated plate rotatably connected to the outer surface of the drive shaft, an upper perforated plate rotatably connected to the outer surface of the lower perforated plate, the inner wall of the upper perforated plate being fixed to the outer surface of the drive shaft, and a mounting ring movably connected to the outer surface of the lower perforated plate, the inner wall of the mounting ring rotating with the outer surface of the upper perforated plate.

[0013] The present invention has the following beneficial effects: 1. In this invention, a flexible filter screen is used in conjunction with a rotating disturbance rod to complete the feeding filtration and auxiliary feeding. Combined with an outer layer of ultrasonic vibration, an internal staggered spiral scraper, and an inner wall air supply triple de-adhesion structure, it can clean the ultra-fine matcha powder adsorbed on the inner wall of the spherical cavity in all directions, with no dead corners in collection. The bottom dynamic and static double-hole plate breaks up the agglomerated powder in real time by relative shear force. The end air-powder separation structure prevents tea powder from entering the negative pressure pipeline. The whole process operates under closed negative pressure, which improves the tea powder recovery rate and reduces material loss.

[0014] 2. In this invention, three sets of scrapers are staggered by 180° in a spiral arrangement. The continuous and slow feeding is achieved by relying on the gentle tilt angle, which avoids high-speed splashing and compaction of powder. The double-layer spherical shell integrates an ultrasonic vibration component, which cleans the wall without damaging the cavity. It is equipped with a detachable wear-resistant scraper strip. Only consumable parts need to be replaced in the later stage, resulting in lower maintenance costs. The whole machine integrates impurity filtration, cavity wall powder cleaning, anti-caking, and gas-powder separation functions from top to bottom. It does not require multiple devices to be connected in series, has a compact structure, and occupies less workshop space. Attached Figure Description

The wall scraping component 13 includes a main shaft 131, an upper scraper 132 and a lower scraper 133 are fixedly connected to the outer surface of the main shaft 131, a wall scraping strip 134 is movably connected to the outer surface of the upper scraper 132 and the lower scraper 133, and a disturbance rod 135 is fixedly connected to the top of the main shaft 131. Specifically, the bottom of the gathering mechanism 1 is connected to the collection mechanism 2, which serves as the main body for collecting tea powder. It is composed of a vibrating shell component 11, a top filtering component 12, and an internal scraping component 13. The bottom of the vibrating shell component 11 is connected to the collection mechanism 2 to realize powder conveying. The scraping component 13 is centered on the main shaft 131. The upper scraper 132 and the lower scraper 133 are fixed on the outside of the main shaft 131. The scraper strip 134 can be detachably installed on the outside of the scraper to scrape off the tea powder adhering to the inner wall of the shell. The top of the main shaft 131 is provided with a disturbance rod 135, which can cooperate with the upper filtering component 12 to disturb the material and clear the filter screen. All components are linked synchronously.

[0019] Please see the appendix Figure 3 Appendix Figure 4 and attached Figure 5The vibrating shell component 11 includes a spliced ​​spherical shell 111, with a dustproof spherical shell 112 movably connected to the inner wall of the spliced ​​spherical shell 111. A baffle ring 113 is fixedly connected to the inner wall of the dustproof spherical shell 112, and a filter element 114 is fixedly connected to the inner wall of the dustproof spherical shell 112. The filtration component 12 includes a feed pipe 121, with a mounting frame 122 fixedly connected to the inner wall of the feed pipe 121. A filter screen 123 is movably connected to the inner wall of the mounting frame 122. The outer surface of the feed pipe 121 is fixed to the inner wall of the dustproof spherical shell 112, and the outer surface of the scraper strip 134 is fixed to the inner wall of the dustproof spherical shell 112. The inner wall of the shell 112 slides against each other, the outer surface of the disturbance rod 135 slides against the outer surface of the filter screen 123, the upper scraper 132 is set on top of the lower scraper 133, there are three upper scrapers 132 and lower scrapers 133, and each upper scraper 132 and lower scraper 133 forms a scraping unit. The upper scraper 132 and lower scraper 133 in each scraping unit are staggered by 180° around the axis of the main shaft 131 and distributed on the surface of the main shaft 131. The upper scraper 132 and lower scraper 133 are inclined at an angle of 20° to the axis of the main shaft 131. Specifically, the feed pipe 121 relies on the mounting frame 122 to assemble a flexible filter screen 123 to complete the feeding and impurity removal. The main shaft 131 drives the agitator 135 to rotate and slide against the filter screen 123, continuously agitating the material on the surface of the filter screen to prevent clogging and assist the tea powder to fall. The tea powder enters the dustproof shell 112. The filter screen 123 is made of antistatic, wear-resistant, smooth, soft, and highly resilient food-grade antistatic conductive polyurethane material. It can quickly rebound when bent under pressure. During installation, a slack is allowed and it should not be completely tightened. During use, there is no debris falling off or harmful substances leaching out, effectively reducing the adhesion of matcha powder. The baffle ring 113 blocks... Dust flows upwards, and the filter element 114 conveys airflow inwards to assist the powder to move downwards. The main shaft 131 is equipped with three sets of scraping units, each set consisting of an upper scraper 132 and a lower scraper 133. The two scrapers in the unit are arranged 180° off along the axis of the main shaft, and the scrapers are inclined at a 20° angle to the axis of the main shaft to form a spiral pushing structure. The scraping strip 134 on the outer side of the scraper slides against the inner wall of the dustproof spherical shell 112. The upper scraper 132 and the lower scraper 133 take turns scraping away the tea powder adhering to the cavity wall, realizing continuous scraping of the spherical inner wall without dead corners. The dustproof spherical shell 112 is matched with a spliced ​​spherical shell 111 to form a double-layer shell structure, providing an installation carrier for the ultrasonic vibration component.

[0020] Please see the appendix Figure 6 Appendix Figure 7The collection mechanism 2 includes a storage component 21, inside which an anti-caking component 22 is installed. The surface of the storage component 21 is in contact with the bottom of the vibrating shell component 11. The storage component 21 includes a collection box 211, with an air-powder separator 212 fixedly connected to the inner wall of the collection box 211. A negative pressure pipe 213 is fixedly connected to the surface of the collection box 211, with the air-powder separator 212 located at the end of the negative pressure pipe 213. A discharge pipe 214 is movably connected to the top of the collection box 211, with the outer surface of the discharge pipe 214 fixed to the inner wall of the dustproof shell 112. The anti-caking component... Component 22 includes a drive component 221. A frame plate 222 is fixedly connected to the outer surface of the drive component 221. The end of the frame plate 222 is fixed to the inner wall of the discharge pipe 214. A drive shaft 223 is fixedly connected to the end of the drive component 221. A lower hole plate 224 is rotatably connected to the outer surface of the drive shaft 223. An upper hole plate 225 is rotatably connected to the outer surface of the lower hole plate 224. The inner wall of the upper hole plate 225 is fixed to the outer surface of the drive shaft 223. A mounting ring 226 is movably connected to the outer surface of the lower hole plate 224. The inner wall of the mounting ring 226 rotates with the outer surface of the upper hole plate 225. Specifically, the inner wall of the discharge pipe 214 is fixed with the drive component 221 by the frame plate 222. The drive component 221 drives the transmission shaft 223 to rotate synchronously. The transmission shaft 223 is fixed to the upper perforated plate 225. The upper perforated plate 225 rotates synchronously with the transmission shaft 223. The lower perforated plate 224 is kept stationary by the limit of the mounting ring 226. The relative rotation of the two perforated plates generates a shearing effect, breaking up the clumps of tea powder and achieving anti-clumping discharge. The side wall of the collection box 211 is connected to the negative pressure pipe 213 and externally connected to the negative pressure system. The end of the negative pressure pipe 213 is equipped with an air-powder separator 212, which can intercept tea powder and only allow airflow to pass through, avoiding fine powder from being sucked into the negative pressure system, causing material loss and pipeline blockage.

[0021] Working principle: During operation, tea powder enters the device through the feed pipe 121 and falls onto the flexible filter screen 123 within the mounting frame 122 to remove large particles of impurities. The disturbance rod 135 at the top of the main shaft 131 rotates with the shaft and presses into the flexible filter screen 123 to form a moving indentation. The wave-like deformation of the filter screen 123 pushes the tea powder to fall faster. The filter screen 123 has a precision of 200-300 mesh. It also widens the mesh openings to squeeze out stuck powder particles, achieving self-cleaning. After the tea powder enters the dustproof spherical shell 112, the baffle ring 113... To prevent dust from rising, the filter element 114 introduces clean airflow into the cavity, which flows downwards along the wall. Combined with the suction force generated by the negative pressure system connected to the negative pressure pipe 213, a stable downward flow field is formed, continuously guiding the tea powder downwards. An ultrasonic vibration transmitter, mounted on the inner wall of the spliced ​​spherical shell 111, is fitted onto the outer wall of the dustproof spherical shell 112 and transmits ultrasonic waves through the wall surface. The ultrasonic frequency is 30–36 kHz and is a continuous pulse, shaking off the ultrafine tea powder adhering to the inner wall. This, along with the upper scraper driven by the main shaft 131, further enhances the effect. Scraper 132 and lower scraper 133, each pair of scrapers are spirally distributed at a 20° inclination angle and staggered by 180°, and the main shaft 131 rotates at a speed of 30-60 r / min. The wall scraper 134 continuously scrapes away the powder layer from the wall surface. The wall scraper 134 is made of food-grade conductive polyurethane with a Shore hardness of A60-70, and is self-antistatic, eliminating electrostatic adsorption of matcha ultrafine powder and preventing powder sticking. The upper scraper 132 and lower scraper 133 relay-push the powder smoothly to the discharge pipe 214. Before entering the collection box 211, the drive unit 221 drives the upper perforated plate 225 to rotate through the transmission shaft 223, forming a relative shearing motion with the fixed lower perforated plate 224, which breaks up any powder that may clump and causes it to fall into the collection box 211. The gas-powder separator 212, located at the end of the negative pressure pipe 213, intercepts the tea powder to prevent it from entering the negative pressure pipe 213 and the subsequent negative pressure system. The negative pressure provided in the negative pressure system is -1800 to -2200 Pa, and the gas is discharged through the negative pressure pipe 213, achieving dust-free and efficient collection.
