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] A tea air separator is a device used for grading and sorting tea leaves in the refining process. It uses the air force of a fan to separate tea leaves according to their bulk density. The air volume and speed of the fan are adjustable, allowing the tea air separator to adapt to the processing needs of different teas.

[0003] When using a tea processing air separator to perform air separation operations on tea leaves, a cloth bag needs to be connected to the discharge end of the air separator to collect qualified tea leaves, while unqualified tea leaves are discharged through the discharge hopper at the bottom of the air separator. However, since the cloth bag is directly fitted onto the discharge end of the air separator, it is easy for it to detach from the air separator under external force, which will cause the tea leaves to fall to the ground, become contaminated, and be wasted. Utility Model Content

[0004] This utility model proposes an air separator for tea processing to solve the problem that the cloth bag is directly fitted onto the discharge end of the air separator, and can easily detach from the air separator under external force, which will cause the tea leaves to fall to the ground and be contaminated, resulting in waste.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a wind separator for tea processing, comprising a chamber, a fan at one end of the chamber, a feed hopper fixedly connected to one side of the top of the chamber, a protective device at the top of the feed hopper, a cloth bag fitted on the outer surface of the other end of the chamber, a fixing device between the chamber and the cloth bag, the fixing device fixing the four sides of the chamber and the cloth bag respectively by four L-shaped plates, a discharge hopper fixedly connected to the bottom of the chamber, and the same support frame fixedly connected to the four corners of the bottom of the chamber.

[0006] The effect achieved by the above components is that by setting four L-shaped plates, the discharge end of the cloth bag and the hopper can be fixed, thereby preventing the cloth bag from falling off the air separator under the action of external force and reducing the waste of tea leaves.

[0007] Preferably, the fixing device includes an auxiliary ring, the inner wall of which is fixedly connected to the outer surface of the container body. The auxiliary ring is disposed on one side of the bag. L-shaped plates are rotatably connected to all four sides of the auxiliary ring. A collar is slidably disposed on the outer surface of the auxiliary ring. Three push blocks are evenly fixedly connected to all four sides of the collar. The bottom of the push blocks is arc-shaped. Springs are symmetrically fixedly connected to both sides of the collar. An extension block is fixedly connected to one end of each spring. One end of the extension block is fixedly connected to one side of the container body.

[0008] The effect achieved by the above components is as follows: under the action of springs, when the springs are not affected by external forces, they will squeeze the collar, causing the collar to drive the push block to move on the auxiliary ring. When the push block moves to one side of the L-shaped plate and abuts, its arc-shaped bottom will push the push block against the L-shaped plate, causing the L-shaped plate to rotate until one side of the L-shaped plate abuts against the cloth bag. Thus, the four L-shaped plates can fix the cloth bag and the hopper body.

[0009] Preferably, the spring has a round rod and a cylinder inside, the outer surface of the round rod is slidably connected to the inner wall of the cylinder, one end of the round rod is fixedly connected to one side of the collar, and one end of the cylinder is fixedly connected to one side of the extension block.

[0010] The effect achieved by the above components is that by setting the round rod and the round cylinder, the spring can be limited, which helps to prevent the spring from bending when deformed.

[0011] Preferably, the outer surface of the collar is symmetrically threaded with threaded pins, and the threaded pins are located on one side of the auxiliary ring.

[0012] The effect achieved by the above components is as follows: by setting the threaded pin and rotating the threaded pin, one end of the threaded pin abuts against the outer surface of the auxiliary ring, so that the threaded pin can assist in fixing the push block connected to the collar, which helps to prevent the L-shaped plate from loosening its fixation on the cloth bag.

[0013] Preferably, rubber strips are symmetrically fixedly connected to the inner walls on both sides of the auxiliary ring, and one end of each rubber strip is provided with a threaded pin.

[0014] The effect achieved by the above components is that by setting a rubber strip, one side of the auxiliary ring can be replaced to abut against one end of the threaded pin, increasing the friction between the threaded pin and the auxiliary ring, making the threaded pin more securely fixed to the push block.

[0015] Preferably, the protective device includes a support plate, which is fixedly installed on the top of the hopper body, and one side of the support plate is fixedly connected to one side of the top of the feed hopper. The top of the feed hopper and the support plate are provided with the same protective plate. A threaded rod is rotatably connected to one side of the protective plate, and an extension plate is threadedly connected to the outer surface of the threaded rod. One side of the extension plate is fixedly connected to one side of the top of the support plate.

[0016] The effect achieved by the above components is as follows: by setting up a protective plate and rotating the threaded rod, the threaded rod will extend and retract on the inner wall of the extension plate. During the extension and retraction process, the threaded rod will drive the protective plate to move until the protective plate completely covers the top of the feed hopper, thus preventing impurities from entering the interior of the chamber through the feed hopper and contaminating the tea.

[0017] Preferably, the top of the feed hopper and the support plate are provided with the same chute, and the bottom of the protective plate is fixedly connected to a slider, the outer surface of the slider being slidably connected to the inner wall of the chute.

[0018] The effect achieved by the above components is that, by setting sliders and grooves, the protective plate can be moved and guided.

[0019] Preferably, one end of the threaded rod is fixedly connected to an operating block, and the outer surface of the operating block is provided with a protrusion.

[0020] The effect achieved by the above components is as follows: by setting the operating block, rotating the operating block can drive the threaded rod to rotate. At the same time, the outer surface of the operating block is provided with protrusions, which can effectively increase the friction of the outer surface of the operating block and have an anti-slip effect when rotating the operating block.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, by setting four L-shaped plates, under the action of springs, the springs will push the push block to move, and the push block will push the L-shaped plates until one side of the L-shaped plate abuts against the cloth bag. Then, the four L-shaped plates can fix the cloth bag and the chamber body, which helps to prevent the cloth bag from falling off the air separator under the action of external force and reduce the waste of tea leaves.

[0028] Example 1, referring to Figures 1-3 As shown in the figure, this embodiment discloses a wind separator for tea processing, including a chamber 1. A fan 4 is provided at one end of the chamber 1. A feed hopper 5 is fixedly connected to one side of the top of the chamber 1. A protective device 3 is provided on the top of the feed hopper 5. A cloth bag 6 is fitted on the outer surface of the other end of the chamber 1. A fixing device 2 is provided between the chamber 1 and the cloth bag 6. The fixing device 2 fixes the four sides of the chamber 1 and the cloth bag 6 respectively through four L-shaped plates 21. A discharge hopper 7 is fixedly connected to the bottom of the chamber 1. The same support frame 8 is fixedly connected to the four corners of the bottom of the chamber 1. By setting four L-shaped plates 21, the cloth bag 6 and the discharge end of the chamber 1 can be fixed, thereby preventing the cloth bag 6 from falling off the wind separator under the action of external force and reducing the waste of tea.

[0029] Reference Figure 2 and Figure 3 As shown, the fixing device 2 includes an auxiliary ring 22. The inner wall of the auxiliary ring 22 is fixedly connected to the outer surface of the compartment 1. The auxiliary ring 22 is located on one side of the cloth bag 6. L-shaped plates 21 are rotatably connected to all four sides of the auxiliary ring 22. A collar 23 is slidably arranged on the outer surface of the auxiliary ring 22. Three push blocks 24 are evenly fixedly connected to all four sides of the collar 23. The bottom of the push blocks 24 is arc-shaped. Springs 26 are symmetrically fixedly connected to both sides of the collar 23. An extension block 25 is fixedly connected to one end of the spring 26. One end of the extension block 25 is fixedly connected to one side of the compartment 1. Through the four L-shaped plates 21, under the action of the springs 26, when there is no external force, the springs 26 will squeeze the collar 23, causing the collar 23 to drive the push blocks. 24 moves on the auxiliary ring 22. When the push block 24 moves to abut against one side of the L-shaped plate 21, its arc-shaped bottom will cause the push block 24 to push the L-shaped plate 21, causing the L-shaped plate 21 to rotate until one side of the L-shaped plate 21 abuts against the cloth bag 6. Then the four L-shaped plates 21 can fix the cloth bag 6 and the compartment 1. The spring 26 is provided with a round rod 29 and a cylinder 210 inside. The outer surface of the round rod 29 is slidably connected to the inner wall of the cylinder 210. One end of the round rod 29 is fixedly connected to one side of the collar 23, and one end of the cylinder 210 is fixedly connected to one side of the extension block 25. By setting the round rod 29 and the cylinder 210, the spring 26 can be limited, which helps to prevent the spring 26 from bending when deformed.

[0030] Reference Figure 2 and Figure 3As shown, bolts 27 are symmetrically threaded onto the outer surface of the collar 23. The bolts 27 are located on one side of the auxiliary ring 22. By rotating the bolts 27, one end of the bolts 27 abuts against the outer surface of the auxiliary ring 22, thus providing auxiliary fixation for the push block 24 connected to the collar 23. This helps prevent the L-shaped plate 21 from loosening its fixation on the cloth bag 6. Rubber strips 28 are symmetrically fixed to the inner walls on both sides of the auxiliary ring 22. The rubber strips 28 are located at one end of the bolts 27. By using the rubber strips 28, one side of the auxiliary ring 22 can abut against one end of the bolts 27, increasing the friction between the bolts 27 and the auxiliary ring 22, making the fixation of the push block 24 by the bolts 27 more stable.

[0031] Reference Figure 2 and Figure 4 As shown, the protective device 3 includes a support plate 31, which is fixedly installed on the top of the silo 1. One side of the support plate 31 is fixedly connected to one side of the top of the feed hopper 5. The top of the feed hopper 5 and the support plate 31 are provided with the same protective plate 32. A threaded rod 33 is rotatably connected to one side of the protective plate 32. An extension plate 34 is threadedly connected to the outer surface of the threaded rod 33. One side of the extension plate 34 is fixedly connected to one side of the top of the support plate 31. By setting the protective plate 32 and rotating the threaded rod 33, the threaded rod 33 will extend and retract on the inner wall of the extension plate 34. During the extension and retraction process, the threaded rod 33 will drive the protective plate 32 to move until the protective plate 32 completely covers the top of the feed hopper 5, thus preventing impurities from entering the interior of the silo 1 through the feed hopper 5 and contaminating the tea.

[0032] Reference Figure 2 and Figure 4 As shown, the top of the feed hopper 5 and the support plate 31 are provided with the same slide groove 36. The bottom of the protective plate 32 is fixedly connected to a slider 35. The outer surface of the slider 35 is slidably connected to the inner wall of the slide groove 36. By setting the slider 35 and the slide groove 36, the protective plate 32 can be moved and guided. One end of the threaded rod 33 is fixedly connected to an operating block 37. The outer surface of the operating block 37 is provided with a protrusion. By setting the operating block 37, rotating the operating block 37 can drive the threaded rod 33 to rotate. At the same time, the protrusion on the outer surface of the operating block 37 can effectively increase the friction of the outer surface of the operating block 37, and has an anti-slip effect when rotating the operating block 37.

[0033] Working principle: When spring 26 is not affected by external force, it will compress collar 23, causing collar 23 to drive push block 24 to move on auxiliary ring 22. When push block 24 moves to abut against one side of L-shaped plate 21, its arc-shaped bottom will push push block 24 against L-shaped plate 21, causing L-shaped plate 21 to rotate until one side of L-shaped plate 21 abuts against cloth bag 6. Then rotate threaded pin so that one end of threaded pin abuts against rubber strip 28 on one side of auxiliary ring 22, thus the threaded pin can... The push block 24 connected to the collar 23 can be used to assist in fixing the L-shaped plate 21 to the cloth bag 6, which helps to prevent the L-shaped plate 21 from loosening. Then, the four L-shaped plates 21 can fix the cloth bag 6 and the hopper 1. Rotating the operating block 37 drives the threaded rod 33 to rotate. Under the limit of the slider 35 and the slide groove 36, the threaded rod 33 will drive the protective plate 32 to move until the protective plate 32 completely blocks the top of the feed hopper 5, which can prevent impurities from entering the interior of the hopper 1 through the feed hopper 5 and contaminating the tea.
