Description

Technical Field

[0001] The present application relates to the technical field of tea processing equipment, and in particular to a dust removal device for tea processing. Background Art

[0002] Tea originated in China, and was first used as a sacrificial offering.

[0003] Tea can be divided into spring tea, summer tea, autumn tea and winter tea according to the season of picking. Tea can be divided into green tea, black tea, oolong tea, white tea, yellow tea, dark tea and other processed tea according to the category. The tea processing process must go through the steps of rolling and drying, and rolling is usually done by hand or machine. The rolling process will inevitably produce powder and dust, which will affect the quality of the tea, so the tea needs to be dusted.

[0004] The existing tea dust removal device is difficult to filter the larger tea leaves and clean the dust attached to the surface of the tea leaves at the same time when removing tea leaves, resulting in low tea dust removal efficiency and difficulty in ensuring the final tea dust removal effect.

[0005] Useful content

[0006] Based on this, it is necessary to provide a dust removal device for tea processing to address the problem that existing tea dust removal devices are difficult to simultaneously perform two steps of filtering larger tea fragments and cleaning the dust attached to the surface of the tea leaves, resulting in low tea dust removal efficiency and difficulty in ensuring the final tea dust removal effect.

[0007] The present application provides a dust removal device for tea processing, comprising:

[0008] A dust removal box, the dust removal box comprising a feed inlet, a box body and a discharge outlet; a receiving space is provided inside the box body;

[0009] A dust removal component, the dust removal component is arranged in the accommodating space inside the box body, the dust removal component includes a fan, a ventilation duct, a material discharge duct and a filter plate, the inlet of the material discharge duct is connected to the ventilation duct, the outlet of the material discharge duct is connected to the material discharge port, the fan is fixedly connected to the box body, the fan is fixedly connected to the ventilation duct, and the filter plate is fixedly connected to the ventilation duct;

[0010] An adsorption component is arranged on the material discharge channel, and the adsorption component includes a first electrostatic roller, a second electrostatic roller and a drive motor. The first electrostatic roller is embedded in the left wall of the material discharge channel, and the second electrostatic roller is embedded in the right wall of the material discharge channel. The drive motor is fixedly connected to the box body, and the first electrostatic roller and the second electrostatic roller are both fixedly connected to the drive shaft of the drive motor.

[0011] The present application relates to a dust removal device for tea processing. Tea leaves enter the ventilation duct in a box through a feed inlet. The tea leaves fall from the ventilation duct to a feed channel due to gravity. During the falling process of the tea leaves, a fan blows air toward the falling route of the tea leaves, thereby separating the tea leaves from crushed powder mixed therein. The separated crushed powder enters a recovery chamber through a filter plate for unified treatment. After the larger crushed powder in the tea leaves is initially separated, the tea leaves enter the feed channel. The first electrostatic roller and the second electrostatic roller continuously rotate under the drive of a driving motor and attract dust attached to the surface of the tea leaves, thereby completing secondary dust removal of the tea leaves. The dust removal effect and efficiency of the tea leaves are improved through two different dust removal steps. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0021] The present application provides a dust removal device for tea processing.

[0022] like Figures 1 to 3 As shown, in one embodiment of the present application, the dust removal device for tea processing includes a dust removal box 100, a dust removal component 200 and an adsorption component 300.

[0023] The dust removal box 100 includes a feed port 101, a box body 102 and a discharge port 103, and a receiving space is provided inside the box body 102. The dust removal assembly 200 is provided in the box body 102, and includes a fan 201, a ventilation duct 202, a lower material channel 203 and a filter plate 204, the inlet of the lower material channel 203 is communicated with the ventilation duct 202, the outlet of the lower material channel 203 is communicated with the discharge port 103, the fan 201 is fixedly connected to the box body 102, the fan 201 is fixedly connected to the ventilation duct 202, and the filter plate 204 is fixedly connected to the ventilation duct 202. The adsorption component 300 is arranged on the discharge channel 203, and the adsorption component 300 includes a first electrostatic roller 301, a second electrostatic roller 302 and a driving motor 303. The first electrostatic roller 301 is embedded in the left wall of the discharge channel 203, and the second electrostatic roller 302 is embedded in the right wall of the discharge channel 203. The driving motor 303 is fixedly connected to the box body 102, and the first electrostatic roller 301 and the second electrostatic roller 302 are both fixedly connected to the driving shaft 304 of the driving motor 303.

[0024] In this embodiment, tea leaves enter the ventilation duct 202 in the box body 102 through the feed port 101, and the tea leaves fall from the ventilation duct 202 to the discharge duct 203 due to gravity. During the falling process of the tea leaves, the fan 201 blows air in the falling route of the tea leaves, thereby separating the tea leaves from the mixed powder therein, and the separated powder passes through the filter plate 204 and enters the recovery chamber 104 for unified treatment. After the larger powder in the tea leaves are initially separated, the tea leaves enter the discharge duct 203, and the first electrostatic roller 301 and the second electrostatic roller 302 continuously rotate under the drive of the driving motor 303, and attract dust attached to the surface of the tea leaves, thereby completing the secondary dust removal of the tea leaves. The dust removal effect and efficiency of the tea leaves are improved through two different dust removal steps.

[0025] like Figure 1 As shown, in one embodiment of the present application, the inlet of the ventilation duct 202 is connected to the feed port 101, the outlet of the ventilation duct 202 is connected to the inlet of the discharge duct 203, and the connection between the ventilation duct 202 and the discharge duct 203 is configured as an arc convex to the outside of the ventilation duct 202.

[0026] Specifically, the diameter of the inlet of the ventilation channel 202 is equal to the diameter of the feed port 101 .

[0027] In addition to setting the connection between the ventilation duct 202 and the lower material duct 203 to be an arc convex to the outside of the ventilation duct 202, the inlet diameter of the lower material duct 203 can also be enlarged, so that the tea leaves can enter the lower material duct 203 more easily.

[0028] In this embodiment, the tea leaves enter the ventilation duct 202 through the feed port 101. Under the action of gravity, the tea leaves gradually fall and enter the discharge duct 203 through the outlet of the ventilation duct 202. During the falling process, the fan 201 continuously blows air to the tea leaves, thereby separating the tea leaves from the tea leaves. The tea leaves are then stored in the recovery chamber 104 after passing through the filter plate 204 for unified recovery and processing.

[0029] Since the tea leaves are blown by the fan 201 during the falling process, the falling path of the tea leaves will be offset, so that the tea leaves do not fall in a straight line. Therefore, the connection between the ventilation duct 202 and the discharge duct 203 is set to be an arc convex to the outside of the ventilation duct 202, so as to prevent the tea leaves from being trapped on the bottom surface of the ventilation duct 202, so that the tea leaves can smoothly pass through the outlet of the ventilation duct 202 into the discharge duct 203.

[0030] like Figure 1 As shown, in one embodiment of the present application, the central axis of the feed channel 203 and the central axis of the feed port 101 are located on the same straight line.

[0031] Specifically, the central axis of the feed port 101 and the central axis of the discharge port 103 are also located on the same straight line.

[0032] In this embodiment, by arranging the central axis of the feed port 101, the central axis of the feed channel 203 and the central axis of the discharge port 103 on the same straight line, the length of the falling path of the tea leaves is shortened, thereby improving the dust removal efficiency of the tea leaves.

[0033] like Figure 1 As shown, in one embodiment of the present application, there are multiple first electrostatic rollers 301 , and the multiple first electrostatic rollers 301 are arranged at equal intervals on the discharge channel 203 .

[0034] In this embodiment, when the tea leaves pass through the discharge channel 203, the first electrostatic roller 301 and the second electrostatic roller 302 continuously rotate under the rotation of the driving motor 303, and the dust attached to the surface of the tea leaves is adsorbed to the surface of the first conductive roller and the second conductive roller under the action of static electricity, thereby improving the dust removal effect on the tea leaves.

[0035] like Figure 1 As shown, in one embodiment of the present application, there are multiple second electrostatic rollers 302 , and the multiple second electrostatic rollers 302 are arranged at equal intervals on the discharge channel 203 , and the first electrostatic roller 301 and the second electrostatic roller 302 are symmetrically distributed about the central axis of the discharge channel 203 .

[0036] In this embodiment, when the tea leaves pass through the discharge channel 203, the first electrostatic roller 301 and the second electrostatic roller 302 continuously rotate under the rotation of the driving motor 303, and the dust attached to the surface of the tea leaves is adsorbed to the surface of the first conductive roller and the second conductive roller under the action of static electricity, thereby improving the dust removal effect on the tea leaves.

[0037] Since the tea leaves fall at a high speed, a plurality of first electrostatic rollers 301 and a plurality of second electrostatic rollers 302 are arranged on the material discharge channel 203 to improve the dust removal efficiency.

[0038] like Figure 3 As shown, in one embodiment of the present application, the filter plate 204 is arranged in parallel with the fan 201 , and the filter plate 204 is provided with a plurality of filter holes 205 , and the plurality of filter holes 205 are evenly arranged on the side wall of the filter plate 204 .

[0039] Specifically, the diameter of the filter hole 205 should be larger than the diameter of the powder and smaller than the diameter of the tea leaves.

[0040] In this embodiment, when the tea leaves pass through the ventilation duct 202, the fan 201 blows air toward the tea leaves, and the tea leaves and tea leaves powder are separated under the action of the fan 201, and the separated powder passes through the filter holes 205 on the filter plate 204 and enters the recovery chamber 104 for centralized processing.

[0041] Since the diameter of the filter hole 205 is small and only allows the broken pieces to pass through, the tea leaves can be effectively prevented from entering the recovery chamber 104 under the blowing of the fan 201, thereby avoiding mis-separation.

[0042] like Figure 1 As shown, in one embodiment of the present application, the dust removal device for tea processing also includes a scraper plate 105, and there are multiple scraper plates 105. The multiple scraper plates 105 are fixedly connected to the discharge channel 203. When the driving motor 303 drives the first electrostatic roller 301 to rotate, the first electrostatic roller 301 abuts against the side wall of the scraper plate 105.

[0043] Specifically, each of the first electrostatic rollers 301 and each of the second electrostatic rollers 302 is in contact with at least one scraper blade 105 .

[0044] In this embodiment, since the first electrostatic roller 301 and the second electrostatic roller 302 will adsorb the dust attached to the surface of the tea leaves to their own surfaces when working, if the dust on the surface of the first electrostatic roller 301 and the second electrostatic roller 302 is not cleaned in time, the dust removal effect of the first electrostatic roller 301 and the second electrostatic roller 302 will be reduced.

[0045] Therefore, at least one scraper plate 105 is provided for each first electrostatic roller 301 and each electrostatic roller in the discharge channel 203. When the first electrostatic roller 301 and the second electrostatic roller 302 rotate under the drive of the driving motor 303, the surfaces of the first electrostatic roller 301 and the second electrostatic roller 302 will rub against the scraper plate 105 due to the rotation, thereby removing dust on the surfaces of the first electrostatic roller 301 and the second electrostatic roller 302 during the rotation, so as to keep the surfaces of the first electrostatic roller 301 and the second electrostatic roller 302 clean, thereby maintaining the dust removal efficiency of the first electrostatic roller 301 and the second electrostatic roller 302.

[0046] like Figure 2 As shown, in one embodiment of the present application, the box body 102 is a rectangular parallelepiped with a hollow interior, the feed port 101 is arranged on the top surface of the box body 102 , and the discharge port 103 is arranged on the bottom surface of the box body 102 .

[0047] In this embodiment, the tea leaves enter the ventilation duct 202 in the box 102 through the feed port 101, and enter the discharge duct 203 from the ventilation duct 202 under the action of gravity, and complete two-step dust removal of the tea leaves during the falling process. The dust-removed tea leaves are discharged from the discharge port 103 to the outside for subsequent processing.

[0048] like Figure 1 As shown, in one embodiment of the present application, a recovery chamber 104 is opened in the box body 102 , the recovery chamber 104 is communicated with the ventilation duct 202 , and the filter plate 204 is disposed between the ventilation duct 202 and the recovery chamber 104 .

[0049] Specifically, the bottom surface of the recovery chamber 104, the bottom surface of the filter plate 204 and the bottom surface of the fan 201 are in the same horizontal plane.

[0050] In this embodiment, when the tea leaves pass through the ventilation duct 202 to reach the discharge channel 203, the fan 201 blows air to the tea leaves, thereby blowing out the mixed tea leaves. The blown out tea leaves pass through the filter plate 204 and enter the recovery chamber 104, which is convenient for unified treatment.

[0051] like Figure 2 As shown, in one embodiment of the present application, an air inlet duct 106 is provided on the side wall of the box body 102 , and the air inlet of the fan 201 is connected to the air inlet duct 106 .

[0052] Specifically, there may be multiple fans 201 , thereby increasing the total wind force of the fans 201 and further improving the dust removal effect.

[0053] In this embodiment, the fan 201 draws air from the outside through the ventilation duct and transmits the air to the ventilation duct 202, thereby separating the tea leaves passing through the ventilation duct 202 from the crushed tea leaves mixed therein.

[0054] The technical features of the above-described embodiments may be arbitrarily combined, and the execution order of the method steps is not limited. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
