Abstract
Description
Technical Field
[0001] This application relates to the field of screening technology, specifically a circular sieve machine for tea particles. Background Technology
[0002] A circular sieve machine for tea particles is a device that uses mechanical motion (such as horizontal rotation or drum rotation) and sieves of different aperture sizes to finely grade tea leaves. It separates tea leaves according to their particle characteristics through physical means and is a key step in improving the quality of tea during the refining process.
[0003] For example, patent CN207076634U discloses a tea sieve machine. This patent can periodically spray water to clean the cylindrical sieve, remove dust from the sieve holes, effectively prevent sieve blockage, improve work efficiency and the quality of sieved tea. The cylindrical sieve is detachable for easy maintenance and replacement, making it more convenient to use.
[0004] During the screening process, tea particles may have a high moisture content, contain a lot of fine fragments or dust, or have irregular shapes (such as flakes or needles). These particles are prone to accumulate or become embedded in the sieve holes, causing filter blockage, which in turn reduces screening efficiency, resulting in a decrease in particle throughput and a reduction in processing volume.
[0005] Therefore, it is necessary to provide a circular sieve machine for tea particles to solve the above problems.

[0034] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.
[0035] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0036] like Figures 1-2 As shown, this application provides a circular sieve machine for tea particles. This circular sieve machine for tea particles is usually installed on a tea processing production line and is mainly used for the screening process in the refining of tea. Specifically, the circular sieve machine for tea particles includes a support 1 fixedly installed on the tea processing production line and a screening mechanism 2 fixedly installed on the upper end of the support 1. The screening mechanism 2 is used to screen the tea.
[0037] The screening mechanism 2 includes fixed plates 20 fixed at both ends of the support 1, and a screen cylinder 21 is rotatably arranged between the fixed plates 20. It should be noted that the fixed plates 20 at both ends of the support 1 are arranged at different heights, so that the screen cylinder 21 between the fixed plates 20 forms an inclined state. At the same time, multiple sets of screen holes 220 are opened on the screen cylinder 21 to facilitate subsequent screening of multiple tea leaves.
[0038] Meanwhile, an inlet 26 is provided on the higher end of the fixed plate 20. The inlet 26 is connected to the inside of the sieve cylinder 21 so that the tea to be sieved can be introduced into the sieve cylinder 21.
[0039] In order to sieve the tea leaves introduced into the sieve cylinder 21, a rotating shaft 24 is rotatably arranged between the two fixed plates 20 at both ends. At the same time, a motor 23 is fixedly arranged at one end of the bracket 1. The output end of the motor 23 passes through the fixed plate 20 and is fixedly connected to the rotating shaft 24, so that starting the motor 23 can drive the rotating shaft 24 to rotate inside the sieve cylinder 21.
[0040] Meanwhile, a fixing rod 25 is fixedly installed on the outside of the rotating shaft 24, and the other end of the fixing rod 25 is fixedly connected to the inside of the sieve cylinder 21. So when the tea leaves are introduced into the sieve cylinder 21 through the inlet 26, the motor 23 can be started to drive the sieve cylinder 21 to rotate between the fixed plates 20 through the rotating shaft 24, so as to facilitate the sieving of the tea leaves inside.
[0041] Before the tea sieving operation begins, the tea leaves can be introduced into the sieve cylinder 21 through the inlet 26. Then, the motor 23 is started, and the sieve cylinder 21 is rotated between the fixed plates 20 through the rotating shaft 24, thereby pushing the tea particles to move inside the sieve cylinder 21. At the same time, due to the inclined setting of the sieve cylinder 21, the tea particles move downward along the sieve cylinder 21 under the action of gravity. During the movement, tea particles of different sizes can be sieved through the sieve holes 220.
[0042] To prevent tea leaves from clogging the sieve holes 220 on the sieve cylinder 21, such as Figures 2-4 As shown, a scraper assembly 29 is provided on the support 1. The scraper assembly 29 cleans the screen holes 220 on the surface of the screen cylinder 21 by unblocking the screen holes 220.
[0043] The scraping assembly 29 includes a slide groove 291 fixedly opened on both sides of the bracket 1, and an arc plate 292 is slidably arranged between the slide grooves 291. The arc plate 292 is arranged in contact with the surface of the screen cylinder 21, so that the operator can push the arc plate 292 to move along the slide groove 291 in contact with the surface of the screen cylinder 21.
[0044] A fixing plate 294 is fixedly installed at one end of the bracket 1, and a cylinder 290 is fixedly installed on the fixing plate 294. The output end of the cylinder 290 is fixedly connected to one end of the arc plate 292, so that starting the cylinder 290 can drive the arc plate 292 to slide along the slide groove 291.
[0045] Meanwhile, soft bristles 293 are fixedly installed on the arc plate 292, so that when the cylinder 290 pushes the arc plate 292 to move, the tea particles on the sieve hole 220 can be cleaned by the soft bristles 293 on the arc plate 292, thereby achieving the effect of unblocking the sieve hole 220.
[0046] After screening is completed, the cylinder 290 can drive the arc plate 292 and soft bristles 293 to reciprocate on the outside of the screen cylinder 21 under the guidance of the slide groove 291. The soft bristles 293 contact the outside of the screen cylinder 21 to clean the screen holes 220. During the cleaning process, the screen cylinder 21 can be driven to rotate synchronously, thereby further cleaning the surface of the screen cylinder 21.
[0047] Furthermore, the aperture of the sieve hole 220 gradually decreases along the inclined direction of the sieve cylinder 21, so that during the sieving process, larger tea particles will be sieved out first through the larger sieve hole 220, while smaller tea particles will be sieved out through the smaller sieve hole 220 in the subsequent process.
[0048] Furthermore, a receiving pipe 221 is fixedly installed at the lower end of the support 1, directly below the sieve holes 220 of each level. Multiple sets of discharge ports 222 are fixedly installed at the lower end of the receiving pipe 221 so that when the tea particles sieved out of the sieve holes 220 fall freely to the receiving pipe 221, they can be discharged from the equipment through the discharge ports 222. This allows tea particles of different sizes to be sieved out through the sieve holes 220 of different sizes, thereby achieving the effect of graded collection of tea particles.
[0049] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
