Description

Technical Field

[0001] This utility model relates to the field of air separator technology, and in particular to an air separator for tea processing. Background Technology

[0002] The air separator is used to screen tea leaves by removing tea dust through airflow. It consists of a screening bin, a feed hopper, a discharge hopper, a mounting frame, a fan, and a tea dust outlet, all fixed to a support. When using the air separator, the worker places a collection box below both the discharge and tea dust outlets. Then, the worker activates the fan on the mounting frame via the controller and pours the tea leaves into the feed hopper. As the fan blows air outwards, suction is generated inside the screening bin, drawing out the tea dust and separating it from the normal tea leaves. The tea dust then falls from the tea dust outlet into the collection box due to its own weight, while the normal tea leaves fall into the collection box below the discharge hopper, thus completing the tea leaf screening process.

[0003] The inventor discovered in his daily work that when using the air separator, the dust carried by the tea leaves may fall onto the inner wall of the air separator after air separation. In order to avoid the dust affecting the tea leaves, it is necessary to clean the inner wall of the air separator. The usual cleaning method is for workers to reach their arms into the screening bin from the tea dust outlet and then wipe it with a cloth, which may make the whole cleaning process cumbersome and inefficient.

[0030] Reference Figure 1 and Figure 3 As shown, this utility model provides a technical solution: a tea processing air separator includes a screening barrel 4 fixedly connected to a support 1, an mounting frame 10 fixedly connected to the inner wall of the screening barrel 4, a motor 7 installed at the other end of the mounting frame 10, the motor 7 controlling the fan 8 to rotate, a feeding hopper 5 fixedly connected to the right end of the screening barrel 4, a feeding hopper 6 fixedly connected to the upper end of the feeding hopper 5, a cleaning component 2 provided on the inner wall of the screening barrel 4, and a tea dust outlet 9 opened at the lower end of the screening barrel 4.

[0031] Reference Figure 4 and Figure 5As shown in this embodiment: the cleaning component 2 includes mounting rods 27 fixedly connected to both sides of the inner wall of the screening barrel 4. A rotating rod 21 is provided between the two mounting rods 27 via a bearing. A connecting rod 22 is fixedly connected to the arc surface of the rotating rod 21. A grooved rod 23 is fixedly connected to the other end of the connecting rod 22. A mounting plate 24 is provided on the inner wall of the grooved rod 23. A cleaning sponge 25 is detachably connected to the upper end of the mounting plate 24. By setting the cleaning component 2, when cleaning the inner wall of the screening barrel 4, the rotating rod 21 on the mounting rod 27 rotates through the driving mechanism, causing the grooved rod 23 connected to the connecting rod 22 to rotate, and causing the cleaning sponge 25 on the mounting plate 24 to rotate and wipe clean, thereby achieving the cleaning effect of the inner wall of the screening barrel 4 as much as possible. A first spring 26 is fixedly connected to the lower end of the mounting plate 24. The other end of the first spring 26 is fixed to the grooved rod 23. Through the first spring 26, the cleaning sponge 25 contacts the inner wall of the screening barrel 4. The first spring 26 is compressed, and its reverse force pushes the mounting plate 24, making the cleaning sponge 25 rotate and wipe clean. The cleaning sponge 25 is in full contact with the inner wall of the screening bin 4. A square block 28 is slidably inserted into the left end of the rotating rod 21. The square block 28 is inserted into the fan 8 through the mounting rod 27. The motor 7 is started and connected to the fan 8 through a reducer and a coupling.

The other end of the second spring 29 is fixed to the rotating rod 21. By setting the second spring 29, when the square block 28 is inserted into the... When the fan 8 is inside, the second spring 29 is in a compressed state, and its reverse force pushes the square block 28, so that the auxiliary limit of the square block 28 is fixedly connected to the right end of the square block 28. The pull rope 210 passes through the rotating rod 21, stops the fan 8 from rotating, and then pulls the pull rope 210 to pull the square block 28 back into the rotating rod 21, thereby stopping the fan 8 from rotating with the rotating rod 21. The cleaning sponge 25 is connected to the mounting plate 24 by screws. The cleaning sponge 25 can be unscrewed for cleaning.

A positioning rod 33 is slidably inserted into the arc surface of the screening bucket 4. The positioning rod 33 is inserted into the installation ring 32. The arc surface of the positioning rod 33 is provided with a protrusion. The positioning rod 33 is inserted into the installation ring 32, so that the installation ring 32 is further fixed. A third spring 34 is fixedly connected to one end of the positioning rod 33. The other end of the third spring 34 is fixed to the screening bucket 4. By setting the third spring 34, the positioning rod 33 is pulled, thereby assisting in limiting the positioning rod 33.

[0033] Working principle:

[0034] When using the air separator, the worker places a collection box below the feed hopper 5 and another below the tea dust outlet 9. The worker then activates the fan 8 on the mounting bracket 10 via the controller. Next, tea leaves are poured into the feed hopper 6, causing them to fall into the feed hopper 5. As the fan 8 blows air outwards, suction is generated inside the screening bin 4, drawing out the tea dust and separating it from the normal tea leaves. The tea dust then falls from the tea dust outlet 9 into the collection box due to its own weight, while the normal tea leaves fall into the collection box below the feed hopper 5, thus completing the process. The tea leaves are being screened. When cleaning the inner wall of the screening bin 4, the motor 7 (model Huilongfa 1.5KW) is started. The motor 7 is connected to the fan 8 via a reducer and coupling. The fan 8 rotates, causing the square block 28 to rotate, which in turn rotates the rotating rod 21 on the mounting rod 27, causing the grooved rod 23 connected to the connecting rod 22 to rotate. This causes the cleaning sponge 25 on the mounting plate 24 to rotate and wipe, thus achieving the desired cleaning effect on the inner wall of the screening bin 4. The cleaning sponge 25 and the screen are connected by the first spring 26. When the cleaning sponge 25 contacts the inner wall of the screening bin 4, the first spring 26 is compressed, and its reverse force pushes the mounting plate 24, ensuring that the cleaning sponge 25 makes full contact with the inner wall of the screening bin 4. By setting the second spring 29, when the square block 28 is inserted into the fan 8, the second spring 29 is compressed, and its reverse force pushes the square block 28, thus limiting the movement of the auxiliary square block 28 and stopping the fan 8 from rotating. Then, pull the pull rope 210 (to fix the pull rope 210, it can be wound around the rotating rod 21 and then knotted for fixation). The square block 28 is pulled back into the rotating rod 21, thereby stopping the fan 8 from rotating the rotating rod 21. The cleaning sponge 25 is connected to the mounting plate 24 by screws. The cleaning sponge 25 can be unscrewed and then cleaned. The mounting ring 32 is inserted into the screening bucket 4, so that the collection net 31 can collect the fine tea dust. The positioning rod 33 is inserted into the mounting ring 32 to further fix the mounting ring 32. By setting a third spring 34, the positioning rod 33 is pulled, thereby assisting in limiting the positioning rod 33.
