Description

Technical Field

[0001] This utility model relates to the technical field of tea production equipment, and in particular to a tea dust separation device for tea production. Background Technology

[0002] In tea production, the separation of tea dust is a crucial step. Traditional methods rely primarily on manual sorting, which is inefficient, labor-intensive, and offers limited precision. With technological advancements, mechanized separation devices have emerged. However, existing devices still present numerous problems in practical use.

[0003] The current tea dust separation device does not pre-treat the light particles attached to the tea leaves when separating tea dust. During the sieving process, the light particles are not easily removed and remain on the tea leaves after sieving, increasing the workload of the workers. Therefore, a tea dust separation device for tea production is proposed to address the above problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] A tea dust separation device for tea production includes a separator body, a floating debris cleaning mechanism disposed inside both ends of the separator body, and a screening mechanism installed inside the middle part of the separator body. The top of the middle part of the separator body is connected to the bottom of the feed hopper. The floating debris cleaning mechanism includes an air inlet pipe fixed to the right end of the top of the separator body. The left end of the air inlet pipe is connected to the right end of the air blowing pipe. An exhaust fan is installed inside the air blowing pipe. A collection pipe is provided to the left of the air outlet of the air blowing pipe. The left side of the middle part of the collection pipe is connected to the right end of the exhaust pipe. A filter screen is installed at the connection between the collection pipe and the exhaust pipe.

[0006] Preferably, an external gas filter is provided at the middle of the air intake pipe.

[0007] Preferably, the front side of the bottom end of the collecting pipe is connected to the rear end of the discharging pipe, and the discharging pipe is equipped with a detachable partition plate, the top of which is fixedly connected to the bottom of the carrying frame.

[0008] Preferably, the screening mechanism includes side plates fixed at both ends of the separator body. A screening hydraulic rod is installed inside the side plate. The telescopic end of the screening hydraulic rod is fixedly connected to one side of the screening frame. A screening filter screen is installed at the bottom of the screening frame. Tea leaves enter from the feed hopper, pass through the gap between the air blowing pipe and the collection pipe, and fall onto the screening filter screen of the screening frame. An external discharge pipe is provided below the discharge port at the right end of the screening frame. The tea dust screened by the screening filter screen falls into the collection frame through the mesh. The front end of the collection frame is welded to the rear end of the handle. The collection frame is placed inside the bottom end of the base frame. The top of the base frame is vertically connected to the bottom of the middle end of the separator body.

[0009] Preferably, a viewing window is embedded in the interior of the front wall of the separator.

[0010] Compared with the prior art, the beneficial effects of this utility model are: (1) The tea leaves to be separated are poured into the feed hopper. Under the action of gravity, the tea leaves begin to enter the separator. The exhaust fan in the blow pipe at the left end of the air inlet is started. External air is blown out through the air inlet and the blow pipe. Since there is a collection pipe on the left side of the air outlet of the blow pipe, under the action of airflow, light floating objects in the tea leaves, such as tea leaf fragments and impurities, are blown towards the collection pipe. The light floating objects enter the collection pipe with the airflow. After being filtered by the filter screen, the air is discharged through the exhaust pipe, and the floating objects remain in the collection pipe. This can quickly remove the light floating objects attached to the inside of the tea leaves.

[0011] (2) If it is necessary to clean the floating objects in the collection pipe, the exhaust fan can be turned off first, and then the partition plate in the discharge pipe can be pulled out through the handle to allow the floating objects in the collection pipe to be discharged from the discharge pipe for cleaning, thus increasing the convenience of cleaning the floating objects.

[0020] Please see Figure 1-4 This utility model provides an embodiment of a tea dust separation device for tea production, comprising a separator body 1, a floating debris cleaning mechanism disposed inside both ends of the separator body 1, and a screening mechanism 4 installed inside the middle of the separator body 1. The top of the middle of the separator body 1 is connected to the bottom of the feed hopper 2. The floating debris cleaning mechanism includes an air inlet pipe 30 fixed to the right end of the top of the separator body 1. The left end of the air inlet pipe 30 is connected to the right end of the blowing pipe 3. An exhaust fan 31 is installed inside the blowing pipe 3. A collection pipe 33 is provided to the left of the air outlet of the blowing pipe 3. The left side of the middle end of the collection pipe 33 is connected to the right end of the exhaust pipe 34. A filter screen 35 is installed at the connection between the collection pipe 33 and the exhaust pipe 34. An external gas filter screen 32 is provided at the middle of the air inlet pipe 30.

[0021] The front side of the bottom end of the collecting pipe 33 is connected to the rear end of the discharging pipe 71. The discharging pipe 71 is equipped with a detachable partition plate 72. The top of the partition plate 72 is fixedly connected to the bottom of the carrying frame 73.

[0022] The screening mechanism 4 includes side plates 43 fixed at both ends of the separator body 1. A screening hydraulic rod 42 is installed inside the side plate 43. The telescopic end of the screening hydraulic rod 42 is fixedly connected to one side of the screening frame 41. A screening filter screen 44 is installed at the bottom of the screening frame 41. Tea leaves enter from the feed hopper 2, pass through the gap between the air blowing pipe 3 and the collection pipe 33, and fall onto the screening filter screen 44 of the screening frame 41. An external discharge pipe 5 is provided below the discharge port at the right end of the screening frame 41. The tea dust screened by the screening filter screen 44 falls through the mesh and into the collection frame 61. The front end of the collection frame 61 is welded to the rear end of the handle 62. The collection frame 61 is placed inside the bottom end of the base frame 6. The top of the base frame 6 is vertically connected to the bottom of the middle end of the separator body 1. A viewing window 8 is embedded inside the front wall of the separator body 1.

[0023] During use, check that all components of the device are securely installed, ensuring a tight connection between the feed hopper 2 and the top of the separator body 1, with no risk of material leakage. Check that the external gas filter 32 at the middle of the air inlet pipe 30 is clean; if any impurities are present, clean them promptly to ensure smooth airflow. Confirm that the partition plate 72 inside the discharge pipe 71 is installed correctly and that the handle 73 is securely connected. Also, check that the collection frame 61 is placed in a suitable position inside the bottom of the base frame 6.

[0024] The tea leaves to be separated are poured into the feed hopper 2. Under the action of gravity, the tea leaves begin to enter the separator 1. The exhaust fan 31 in the air blowing pipe 3 at the left end of the air inlet pipe 30 is started. External air is blown out through the air inlet pipe 30 and the air blowing pipe 3. Since there is a collection pipe 33 on the left side of the air outlet of the air blowing pipe 3, under the action of airflow, light floating objects in the tea leaves, such as tea fragments and impurities, are blown towards the collection pipe 33. The light floating objects enter the collection pipe 33 with the airflow. After being filtered by the filter screen 35, the air is discharged through the exhaust pipe 34, and the floating objects remain in the collection pipe 33. At this time, the heavier tea leaves continue to fall, pass through the gap between the air blowing pipe 3 and the collection pipe 33, and fall onto the screening filter screen 44 of the screening frame 41 of the screening mechanism 4. The screening hydraulic rod 42 in the side plate 43 of the screening mechanism 4 is started. The telescopic end of the screening hydraulic rod 42 drives the screening frame 41 to reciprocate, so that the tea leaves continuously vibrate and roll on the screening filter screen 44. During this process, tea leaves that fit the mesh size of the sieve filter 44 fall through the mesh and into the collection frame 61 below, while larger tea leaves move within the sieve frame 41. When the tea leaves in the sieve frame 41 move to the discharge port on its right end, they fall from the discharge port into the external discharge pipe 5 and are collected and discharged through the external discharge pipe 5. If it is necessary to clean the floating matter in the collection pipe 33, the exhaust fan 31 can be turned off first, and then the partition plate 72 in the discharge pipe 71 can be pulled out through the handle 73 to allow the floating matter in the collection pipe 33 to be discharged and cleaned from the discharge pipe 71.
