Description

Technical Field

[0001] The utility model relates to the technical field of tea processing equipment, in particular to a finished tea sorting device. Background Art

[0002] Tea winnowing is to separate the light components from the heavy components by using the unequal weights of each component with the help of wind power. Since there are many processes in the tea preparation process, some fine tea fragments or impurities are likely to be generated. By this method, most of the tea fragments or impurities in the finished tea can be separated, improving the quality of the finished tea.

[0003] The Chinese patent "Application No.: CN202220113472.8" discloses "a tea winnowing device, which includes a tea winnowing box, a feeding port for inputting tea into the tea winnowing box, a blower for blowing air into the tea winnowing box, and an air inlet channel connected to the blower; a filter plate for filtering tea is fixed at one end of the tea winnowing box far from the blower; a plurality of demarcation plates for dividing the tea winnowing box into sections are fixed in the tea winnowing box; a plurality of discharge ports for discharging the winnowed tea are fixed at the lower end of the tea winnowing box, and a wind shelter for preventing air from discharging from the discharge port is arranged at the discharge port."

[0004] The solution provided by this patent sets a plurality of demarcation plates in the winnowing box, so that a plurality of collection grooves are formed at the bottom of the winnowing box along the air outlet direction of the blower air, realizing multi-level classification of tea weight while separating tea fragments or impurities. However, there are still differences in the particle size of tea particles with the same weight. For finished tea of the same weight specification, if the particle sizes are different, it will also affect the quality of the finished tea. Therefore, this application proposes a finished tea sorting device that can simultaneously classify the weight grade and particle size grade of tea particles. Summary of the Utility Model

[0005] The main purpose of the utility model is to provide a finished tea sorting device, aiming to solve the technical problem of simultaneous classification of the weight grade and particle size grade of tea particles.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A finished tea sorting device, including a device body with a cavity inside. Opposite ends of the device body are respectively provided with an air injection pipe and an exhaust pipe that communicate with the top of the cavity. On one side of the top of the device body adjacent to the air injection pipe, a feeding hopper communicating with the cavity is provided; at least one baffle is stacked in the cavity in the direction from the air injection pipe close to the exhaust pipe. The bottom end of each baffle is connected to one end of a sieve plate, and the other end of each sieve plate is connected to the side wall of the cavity adjacent to the air injection pipe, so as to divide the bottom of the cavity into at least one sorting groove and an aggregate groove; one end of each sorting groove adjacent to the air injection pipe is respectively connected to an external collection mechanism through a guiding hopper, and the bottom of the aggregate groove is connected to an external collection mechanism through a discharge pipe.

[0008] As a further improvement of the present invention, the end of the air injection pipe away from the cavity is connected to a fan. A retaining net is provided at each end of the air injection pipe and the exhaust pipe adjacent to the cavity. The ends of the air injection pipe and the exhaust pipe adjacent to the cavity are coaxial and parallel to the horizontal plane. The fan works to generate an air flow from the air injection pipe to the exhaust pipe at the top of the cavity.

[0009] As a further improvement of the present invention, the horizontal height of the sieve plate connected to the side wall of the cavity is lower than its horizontal height connected to the baffle, so that the sieve plate forms a slope structure with a preset angle with the horizontal plane.

[0010] As a further improvement of the present invention, the sieve plate is provided with mesh holes, and the mesh holes of each sieve plate gradually decrease in the direction from the top of the cavity to its bottom.

[0011] As a further improvement of the present invention, the bottom surface of the cavity is in a funnel shape, and the low position of the bottom surface of the cavity is connected to one end of the discharge pipe.

[0012] The technical solution provided by the present invention may include the following beneficial effects:

[0013] During the use of the present invention, gas is injected into the cavity through the air injection pipe to generate an air flow from the air injection pipe to the exhaust pipe at the top of the cavity, providing a horizontal thrust for the tea particles entering the top of the cavity. The tea particles and broken tea will produce horizontal displacements of different distances according to their own weights and fall into the sorting groove or the aggregate groove.

[0018] In order to make the purpose, technical solutions, and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Without conflict, the embodiments and features in the embodiments of the present utility model can be combined with each other. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0019] Figure 1 shows an embodiment of a finished tea sorting device of the present utility model. Refer to Figure 1 In this embodiment, a finished tea sorting device includes: device body 1, air injection pipe 2, exhaust pipe 3, feeding hopper 4, discharge hopper, and discharge pipe 8.

[0020] Among them, refer to Figure 1, a hollow cavity 11 is provided inside the device body 1; at two opposite ends of the device body 1, an air injection pipe 2 and an air discharge pipe 3 are respectively provided, and both the air injection pipe 2 and the air discharge pipe 3 are communicated with the top of the cavity 11, so as to blow air to the top of the cavity 11 through the air injection pipe 2; on one side of the top of the device body 1 adjacent to the air injection pipe 2, a charging hopper 4 communicated with the cavity 11 is provided, so as to inject materials into the cavity 11; at least one baffle 5 is stacked inside the cavity 11 in the direction from the air injection pipe 2 close to the air discharge pipe 3, the bottom end of each baffle 5 is connected to one end of a sieve plate 6, and the other end of each sieve plate 6 is connected to the side wall of the cavity 11 adjacent to the air injection pipe 2, so as to separate at least one sorting tank 12 and an aggregate tank 13 at the bottom of the cavity 11, and one end of each sorting tank 12 adjacent to the air injection pipe 2 is respectively connected to an external collection mechanism through a guide hopper 7, and the bottom of the aggregate tank 13 is connected to an external collection mechanism through a discharge pipe 8. When it is necessary to classify the produced tea by grade, gas is injected into the cavity 11 through the air injection pipe 2 and discharged from the air discharge pipe 3, so as to generate a one-way horizontal air flow at the top of the cavity 11; at the same time, tea is injected into the cavity 11 through the charging hopper 4. Under the action of the wind force, the lighter particles are pushed to the side of the cavity 11 adjacent to the air discharge pipe 3, and the particles with similar weights will fall into the same sorting tank 12 or the aggregate tank 13. When the materials in the sorting tank 12 roll into the guide hopper 7, the particles smaller than the aperture of the sieve plate 6 will fall into the next-level sorting tank 12 or the aggregate tank 13. While separating broken tea or impurities, the classification of the tea by weight grade and particle size is realized simultaneously.

[0021] Optionally, the horizontal height of each baffle 5 decreases one by one in the direction from the air injection pipe 2 close to the air discharge pipe 3, so as to conform to the projectile motion generated when the tea particles fall and are affected by the horizontal wind force, and make the weights of the tea particles falling into each sorting tank 12 similar.

[0022] Further, referring to Figure 1 , one end of the air injection pipe 2 far from the cavity 11 is connected to a fan 9, and a retaining net 10 is provided at one end of each of the air injection pipe 2 and the air discharge pipe 3 adjacent to the cavity 11, so as to prevent the tea particles in the cavity 11 from entering the air injection pipe 2 or the air discharge pipe 3; the ends of the air injection pipe 2 and the air discharge pipe 3 adjacent to the cavity 11 are coaxial and parallel to the horizontal plane, so that the fan can do work to inject a horizontal air flow into the top of the cavity 11 and discharge it from the air discharge pipe 3, and provide a horizontal thrust for the tea particles input from the charging hopper 4.

[0023] Further, referring to Figure 1 , the horizontal height of the sieve plate 6 connected to the side wall of the cavity 11 is lower than the horizontal height of the sieve plate 6 connected to the baffle 5, so that the sieve plate 6 forms a slope structure with a preset angle with the horizontal plane, which is convenient for the tea particles falling into the sorting bin to roll out to the corresponding discharge hopper, and at the same time makes the particles with a particle size smaller than the aperture of the sieve plate 6 fall into the next-level sorting tank 12 or the aggregate tank 13.

[0024] Further, referring to Figure 1 , the sieve plate 6 is provided with mesh holes, and the mesh holes of each sieve plate 6 decrease from the top of the cavity 11 towards the bottom thereof, so as to perform particle size grading on particles of the same weight, making the flatness of the sorted tea higher.

[0025] Further, referring to Figure 1 , the bottom surface of the cavity 11 is funnel-shaped, and the lower position of the bottom surface of the cavity 11 is connected to one end of the discharge pipe 8, and the other end of the discharge pipe 8 is connected to an external collection facility, so as to discharge the collected broken tea or tea dregs during the tea sorting process.

[0026] In this embodiment, the produced tea is input into the top of the cavity 11 through the feeding hopper 4. At the same time, the fan works to generate an air flow from the injection air pipe 2 to the exhaust air pipe 3 at the top of the cavity 11, providing a horizontal thrust for the tea particles entering the top of the cavity 11. The tea particles and broken tea will generate horizontal displacements of different distances according to their own weights and fall into the sorting tank 12 or the aggregate tank 13. During the process of the tea particles in the sorting tank 12 rolling to the corresponding discharge hopper, the tea particles or broken tea with a particle size smaller than the aperture of the sieve plate 6 fall into the lower-level sorting tank 12 or the aggregate tank 13. While sorting out the broken tea or impurities, the weight grade and particle size of the tea are classified simultaneously.

[0027] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
