Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, and in particular to an impurity filtration device for tea processing. Background Technology

[0002] As an important raw material for beverages, the cleanliness of tea during processing is crucial. Freshly picked leaves or raw tea after initial processing often contain impurities such as sand, dust, and stems, directly affecting the quality and safety of the finished tea. Therefore, an impurity filtration device for tea processing is a key piece of equipment on the tea refining production line, used to efficiently separate tea leaves from impurities and improve the purity of the tea.

[0003] In existing technologies, tea impurity filtration devices generally adopt the principle of vibrating sieving. The main structure usually includes a fixed base, a support spring, a vibrating screen frame mounted on the spring and with a built-in screen, and a vibrator that drives the screen frame to vibrate. The tea to be sieved falls into the screen frame through the hopper and the feed pipe. Driven by the vibrating motor, the screen frame generates high-frequency micro-amplitude vibration through the support spring, causing the tea to jump forward on the screen. Qualified tea smaller than the screen holes passes through the screen and falls into the collection device below, while impurities larger than the screen holes and some coarse tea leaves remain on the screen surface or move along the screen surface to the discharge port.

[0004] However, existing devices of this type have a significant problem in practical applications. Due to the fixed structure of the feed pipe and the lack of active intervention, when processing tea with high moisture content or prone to clumping, the tea leaves tend to stick and accumulate on the pipe wall, causing blockages, resulting in poor feeding or even complete interruption. This seriously affects continuous production efficiency and screening effect. At the same time, the fixed diameter feed pipe cannot flexibly adjust the feed flow rate according to the type of tea, moisture content, or screening efficiency requirements. It often requires frequent manual intervention, which is cumbersome and difficult to achieve precise control. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an impurity filtration device for tea processing, which aims to improve the problems of easy clogging and inability to adjust the feed flow rate.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a tea processing impurity filtration device, comprising a base, a plurality of springs fixedly connected to the upper surface of the base, a screen frame fixedly connected to one end of each spring, a support arm fixedly connected to the outer wall of the base, a material box fixedly connected to the lower surface of the support arm, a feeding pipe fixedly connected to one end of the material box, a feeding assembly provided on the outer wall of the feeding pipe, and a connecting assembly provided on the outer wall of the screen frame;

[0007] The feeding assembly includes a rotating plate, the inner wall of which is rotatably connected to the bottom of the feeding pipe, an electric telescopic rod rotatably connected to the outer wall of the feeding pipe, the output end of the electric telescopic rod rotatably connected to the outer wall of the rotating plate, a transmission rod is provided inside the material box, a stirring rod is fixedly connected to the outer wall of the transmission rod, and a drive assembly is provided inside the support arm.

[0008] Furthermore, the connecting assembly includes a sealing ring disposed on the outer wall of the screen frame. One end of the sealing ring is fixedly connected to a connecting block one, and a locking shaft is fixedly connected to the inner wall of the connecting block one. The other end of the screen frame is fixedly connected to a connecting block two, and a button is slidably connected inside the connecting block two. A locking block is fixedly connected to the outer wall of the button.

[0009] Furthermore, the locking block is disposed inside the connecting block two, and the outer wall of the locking block is fitted with a spring two.

[0010] Furthermore, one end of the second spring is fixedly connected to the outer wall of the locking block, and the other end of the second spring is fixedly connected to the inner wall of the second connecting block.

[0011] Furthermore, the drive assembly includes a motor, which is disposed inside the support arm, and the output end of the motor is fixedly connected to the inner wall of the transmission rod.

[0012] Furthermore, a discharge port is fixedly connected to the outer wall of the screen frame, and a frame cover is provided on the upper surface of the screen frame.

[0013] Furthermore, a vibration pump is fixedly connected to the bottom of the screen frame, and multiple screen frames are provided.

[0014] Furthermore, the feeding pipe is disposed inside the frame cover, and the rotating plate is disposed inside the frame cover.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the motor drives the transmission rod to drive the stirring rod to rotate continuously in the material box, effectively breaking up tea clumps and preventing them from being lifted out of the box. The electric telescopic rod is simultaneously controlled to extend and retract, pushing the rotating plate to rotate around the axis of the feeding pipe, dynamically adjusting the feeding opening area, eliminating pipe wall blockage caused by wet tea sticking together, and accurately controlling the tea flow rate according to screening requirements, reducing the frequency of manual intervention.

[0017] 2. In this invention, during disassembly, a single press of the button drives the locking block to compress the spring two inward and disengage from the locking shaft, quickly releasing the screen frame lock. During installation, simply align and fit the connecting block one with the connecting block two; the spring two automatically rebounds, pushing the locking block into the locking shaft groove, while simultaneously compressing the sealing ring to form a sealed interface. Compared to the traditional bolt fixing method, this improves disassembly and assembly efficiency and eliminates the problem of powder leakage from the screen frame. Attached Figure Description

A transmission rod 7 is installed inside the material box 6, and a stirring rod 8 is fixedly connected to the outer wall of the transmission rod 7. The stirring rod 8 is spirally arranged to effectively break up tea clumps. A drive component is installed inside the support arm 4. The connecting component includes a sealing ring 21. The sealing ring 21 is disposed on the outer wall of the screen frame 12, surrounding the connection to prevent leakage. One end of the sealing ring 21 is fixedly connected to a connecting block 15, and a locking shaft 16 is fixedly connected to the inner wall of the connecting block 15. The other end of the screen frame 12 is fixedly connected to a connecting block 17. A button 18 is slidably connected inside the connecting block 17 for easy one-handed operation. A locking block 19 is fixedly connected to the outer wall of the button 18. The locking block 19 is disposed inside the connecting block 17. A spring 20 is sleeved on the outer wall of the locking block 19 to provide continuous locking force to ensure connection reliability. One end of the spring 20 is fixedly connected to the outer wall of the locking block 19, and the other end of the spring 20 is fixedly connected to the connecting block.

[0028] Working principle: When using this tea processing impurity filtration device, firstly, the vibration pump 3 inside the base 1 is started to drive the screen frame 12 to vibrate through the spring 2. At the same time, the motor 5 inside the support arm 4 drives the transmission rod 7 to rotate, so that the stirring rod 8 in the material box 6 continuously stirs the tea to break up clumps. When the tea in the material box 6 falls through the feed pipe 9, the electric telescopic rod 10 controls the rotating plate 11 to rotate around the axis of the feed pipe 9, dynamically adjusting the opening area to control the flow rate and prevent blockage. After the tea falls into the screen frame 12 sealed by the frame cover 14, it is screened under the action of vibration. Qualified tea passes through the next layer of the screen and is discharged from the outlet 13, while impurities are discharged from the outlet 13 of this layer. When the screen frame 12 needs to be disassembled, press the button 18 on the connecting block 17 to make the locking block 19 compress the spring 20 and disengage from the locking shaft 16, so that the connecting block 15 can be separated, and the sealing state of the sealing ring 21 can be released at the same time.
