Description

Technical Field

[0001] This utility model relates to the field of green tea processing technology, and in particular to a green tea impurity removal and screening device. Background Technology

[0002] During the green tea production process, due to the limitations of the natural environment of the tea garden and the picking techniques, some impurities, such as branches, leaves, and weeds, are inevitably mixed in. These impurities not only affect the appearance and quality of green tea, but may also have an adverse effect on the taste and flavor. Therefore, it is necessary to remove impurities and sift the tea leaves during the green tea production process.

[0003] A search revealed a Chinese patent for a purification device for green tea processing (authorization announcement number CN220239231U), comprising a fixed box, a screen, a first fixed tube, a second fixed tube, a first air outlet, and a second air outlet. The second air outlet in each group is inclined towards the corresponding first air outlet. The first and second air outlets can alternately emit air. The fixed box can switch between horizontal and inclined states. This patented technology, through the alternating first and second air outlets, not only removes impurities adhering to the green tea but also allows the purified green tea to quickly move away from the first air outlet, thus preventing the green tea from being pushed onto the screen by the air blown out by the first air outlet, preventing the green tea from getting stuck on the screen, and ensuring a smooth purification process.

[0004] However, the above-mentioned device still has some drawbacks in actual use. The most obvious one is that after the above-mentioned impurity removal device separates the green tea from the impurities, the impurity-removed green tea still needs to be put into the drying process for drying. Therefore, it is impossible to remove impurities and dry the green tea at the same time, which increases the processing time of green tea and reduces the processing efficiency of green tea. Utility Model Content

[0005] In view of the above-mentioned problems existing in the prior art, the main purpose of this utility model is to provide a green tea impurity removal and screening device.

[0006] The technical solution of this utility model is as follows: a green tea impurity removal and sieving device includes a base plate, with supports fixedly connected to both ends of the top of the base plate, a processing cylinder fixedly connected between the two supports, a sieving cylinder fixedly installed inside the processing cylinder, sieving holes arrayed inside the sieving cylinder, a drying tube rotatably installed between the two supports, the drying tube penetrating the interior of the processing cylinder and the sieving cylinder, air vents evenly spaced inside the drying tube, stirring plates fixedly connected to both sides of the drying tube, and brushes provided on the side of the stirring plates away from the drying tube.

[0007] By adopting the above technical solution, the drying gas generated by the drying component can be evenly filled into the processing cylinder through the air outlet by the rotation of the drying tube. At the same time, the rotation of the drying tube will drive the stirring plates on both sides to rotate, so that the green tea stuck in the sieve hole can be brushed off by the brush. The rotation of the stirring plates will also turn the green tea accumulated in the processing cylinder, thereby breaking up the impurities adhering to the green tea.

[0008] In a preferred embodiment, a transmission assembly is provided on one side of the base plate. The transmission assembly includes a servo motor fixedly installed on the outside of one of the brackets. A first gear is fixedly connected to the output shaft of the servo motor. One end of the drying tube passes through the bracket and is fixedly connected to a second gear. The second gear meshes with the first gear.

[0009] By adopting the above technical solution, the rotation of the output shaft of the servo motor can drive the first gear to rotate, thereby driving the rotation of the second gear and the drying tube.

[0010] In a preferred embodiment, a drying assembly is provided at one end of the top of the base plate. The drying assembly includes a dryer fixedly installed at one end of the top of the base plate. A connecting pipe is provided at the top of the dryer. A connecting flange is provided between the connecting pipe and the output end of the dryer. The connecting pipe is connected to the output end of the dryer through the connecting flange.

[0011] By adopting the above technical solution, the dryer can fill the interior of the connecting pipe with the generated dry gas, thereby providing a continuous supply of dry gas to the processing cylinder.

[0012] In a preferred embodiment, a rotary joint is fixedly connected to the end of the drying tube away from the second gear, and the end of the connecting tube away from the connecting flange is fixedly connected to the rotary joint.

[0013] By adopting the above technical solution and using the rotary joint, it can be ensured that the rotating drying tube does not affect the connecting tube.

[0014] In a preferred embodiment, a dustproof net is fixedly connected inside each of the air outlets, and a controller is fixedly installed on the outside of one of the brackets.

[0015] By adopting the above technical solution and setting up a dustproof net, internal impurities can be prevented from entering the interior of the drying tube through the air outlet.

[0016] In a preferred embodiment, the processing cylinder has a fixing groove inside, and polyester blocks are disposed inside the fixing groove.

[0017] By adopting the above technical solution, the polyester block material has strong air permeability, which can prevent dust from leaking out.

[0018] In a preferred embodiment, a sealing door is hinged to the outside of the processing cylinder, and the servo motor and the dryer are both electrically connected to the controller.

[0019] By adopting the above technical solution, a sealed door is used to facilitate the loading and unloading of green tea from the processing cylinder.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] 1. In this utility model, after green tea is fed into the processing cylinder, the rotation of the drying tube allows the drying gas generated by the drying component to be evenly injected into the processing cylinder through the air outlet. At the same time, the rotation of the drying tube will drive the stirring plates on both sides to rotate, thereby brushing off the green tea stuck in the sieve holes with a brush, preventing the green tea from clogging the sieve holes and restoring the sieving effect of green tea and impurities. In addition, the rotation of the stirring plates will turn over the green tea accumulated in the processing cylinder, thereby dispersing the impurities adhering to the green tea. This not only improves the drying effect of green tea but also improves the sieving effect, allowing the impurity removal process and the drying process to be carried out simultaneously, thereby reducing the processing time of green tea and improving work efficiency.

[0022] 2. In this utility model, the dryer can fill the interior of the connecting pipe with the generated dry gas, thereby providing a continuous supply of dry gas to the processing cylinder. The connecting flange makes the dryer detachable, and after processing, the connecting flange on the connecting pipe can be connected to the water supply equipment to clean the internal components of the processing cylinder. This makes the structure dual-purpose and improves the practicality of the device. Attached Figure Description

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] Reference Figure 1-3 A green tea impurity removal and sieving device includes a base plate 1, with supports 2 fixedly connected to both ends of the top of the base plate 1. A processing cylinder 3 is fixedly connected between the two supports 2, and a sieving cylinder 10 is fixedly installed inside the processing cylinder 3. The sieving cylinder 10 has sieving holes 11 arranged inside. A drying tube 8 is rotatably installed between the two supports 2, penetrating the interior of the processing cylinder 3 and the sieving cylinder 10. Air vents 17 are equidistantly opened inside the drying tube 8. Stirring plates 9 are fixedly connected to both sides of the drying tube 8, and brushes are provided on the side of the stirring plates 9 away from the drying tube 8. After green tea is fed into the processing cylinder 3, the rotation of the drying tube 8 allows the air vents 17 to be used to remove impurities and sieving the tea. The drying gas generated by the drying component is evenly injected into the processing cylinder 3. At the same time, as the drying tube 8 rotates, it drives the stirring plates 9 on both sides to rotate. This allows the green tea stuck in the sieve holes 11 to be brushed off with a brush, preventing the green tea from clogging the sieve holes 11 and restoring the sieving effect of green tea and impurities. The rotation of the stirring plates 9 also agitates the green tea accumulated in the processing cylinder 3, thereby breaking up the impurities adhering to the green tea. This not only improves the drying effect of green tea but also improves the sieving effect, allowing the impurity removal process and the drying process to be carried out simultaneously. This reduces the processing time of green tea and improves work efficiency.

[0029] Reference Figure 1 A transmission assembly is provided on one side of the base plate 1. The transmission assembly includes a servo motor 4 fixedly installed on the outside of one of the brackets 2. A first gear 5 is fixedly connected to the output shaft of the servo motor 4. One end of the drying tube 8 passes through the bracket 2 and is fixedly connected to a second gear 6. The second gear 6 meshes with the first gear 5. The gear ratio between the first gear 5 and the second gear 6 is 4:1. The rotation speed of the drying tube 8 can be increased by the large gear driving the small gear to rotate.

[0030] Reference Figure 2A drying assembly is provided at one end of the top of the base plate 1. The drying assembly includes a dryer 13 fixedly installed at one end of the top of the base plate 1. A connecting pipe 15 is provided at the top of the dryer 13. A connecting flange 14 is provided between the connecting pipe 15 and the output end of the dryer 13. The connecting pipe 15 and the output end of the dryer 13 are connected through the connecting flange 14. Through the action of the dryer 13, the generated drying gas can be filled into the interior of the connecting pipe 15, thereby providing a continuous supply of drying gas to the processing cylinder 3. The setting of the connecting flange 14 makes the dryer 13 detachable. After processing, the connecting flange 14 on the connecting pipe 15 can be connected to a water supply device, thereby enabling the cleaning operation of the internal components of the processing cylinder 3. This makes the structure dual-purpose and improves the practicality of the device.

[0031] Reference Figure 2 A rotary joint 16 is fixedly connected to the end of the drying tube 8 away from the second gear 6, and the end of the connecting tube 15 away from the connecting flange 14 is fixedly connected to the rotary joint 16. The rotary joint 16 ensures that the rotating drying tube 8 does not affect the connecting tube 15, thus ensuring the normal operation of the connecting tube 15.

[0032] Reference Figure 1 Each of the air outlets 17 is fixedly connected with a dustproof net 18. A controller 7 is fixedly installed on the outside of one of the brackets 2. The dustproof net 18 can prevent internal impurities from entering the interior of the drying tube 8 through the air outlet 17.

[0033] Reference Figure 2 The processing cylinder 3 has a fixed groove inside, and a polyester block 12 is placed inside the fixed groove. The polyester block 12 has strong air permeability and can prevent dust from leaking out, allowing the gas filled into the processing cylinder 3 to be discharged through the fixed groove.

[0034] Reference Figure 1 The processing cylinder 3 is hinged to a sealing door on the outside. The servo motor 4 and the dryer 13 are both electrically connected to the controller 7. The sealing door facilitates the loading and unloading of green tea from the processing cylinder 3.

[0035] Working principle: First, the transmission component is controlled by the controller 7 to operate, so that the sealing door on the processing cylinder 3 faces the operator. Then, the sealing door is opened and green tea is put into the processing cylinder 3. The sealing door is closed, and then the dryer 13 and servo motor 4 are started. The rotation of the output shaft of the servo motor 4 can drive the first gear 5 to rotate, thereby driving the second gear 6 and the drying tube 8 to rotate.

[0036] Then, by rotating the drying tube 8, the drying gas generated by the dryer 13 can be evenly filled into the processing cylinder 3 through the air outlet 17. At the same time, during the rotation of the drying tube 8, the stirring plates 9 on both sides of it will rotate, so that the green tea stuck in the sieve hole 11 can be brushed off with a brush, so as to avoid the green tea from clogging the sieve hole 11. The rotation of the stirring plate 9 will turn over the green tea accumulated in the processing cylinder 3, thereby breaking up the impurities adhering to the green tea. This not only improves the drying effect of the green tea, but also improves the sieving effect, so that the impurity removal process and the drying process can be carried out simultaneously.

[0037] Finally, when the processing is completed, the connecting flange 14 on the connecting pipe 15 can be connected to the water supply equipment, so that the internal components of the processing cylinder 3 can be cleaned. This allows the drying pipe 8, the stirring plate 9, and the connecting pipe 15 to be used in two ways, improving the practicality of the device.
