Description

Technical Field

[0001] This utility model relates to the technical field of lithium mica disc granulation device, and in particular to a dust-proof lithium mica disc granulation device. Background Technology

[0002] Lithium mica granulation is a key process in mineral processing, aiming to agglomerate powdered materials into regular particles to improve the stability of subsequent applications. Traditional disc granulation devices suffer from significant problems during operation: First, the feeding and mixing stages easily generate large amounts of dust, leading to environmental pollution and raw material loss; second, existing dust suppression systems typically use a single spray mode, failing to differentiate dust control based on the characteristics of different processes (such as feeding and mixing), resulting in water waste or insufficient dust suppression effectiveness. Furthermore, routine sampling requires stopping equipment operation, affecting production continuity, and manual sampling is prone to insufficient sample representativeness or secondary contamination. To address these issues, there is an urgent need to develop a granulation device with staged dust suppression control, dynamic online sampling, and real-time quality monitoring capabilities to improve process efficiency and environmental performance. Utility Model Content

[0003] The purpose of this invention is to solve the above-mentioned problems by providing a dust-proof lithium mica disc granulation device.

[0004] The technical solution of this utility model is implemented as follows:

[0005] This utility model provides a dust-proof lithium mica disc granulation device, the granulation device comprising:

[0006] Base;

[0007] A granulation disc is rotatably mounted on the base, wherein a support frame passing over the granulation disc is mounted on the base;

[0008] The feed inlet is located above the granulation disc and is used to vertically feed materials onto the granulation disc.

[0009] A water spray pipe is installed on the support frame, and the water spray pipe includes a feeding dust suppression spray pipe and a stirring dust suppression spray pipe;

[0010] Multiple feeding dust suppression nozzles and stirring dust suppression nozzles are arranged along the axial direction of the water spray pipe;

[0011] In this configuration, the nozzles of each of the feeding dust suppression nozzles are upward and tilted toward the feed inlet, while the nozzles of the stirring dust suppression nozzles are downward toward the granulation disc.

[0012] The advantages or beneficial effects of the above technical solutions include at least the following:

[0013] 1. Staged dust suppression design: By setting up independent feeding dust suppression spray pipes and mixing dust suppression spray pipes, and controlling the water supply pipeline separately, the spraying strategy can be flexibly adjusted for the high dust stage of feeding and the low dust stage of mixing, so as to achieve precise dust suppression and avoid water waste.

[0014] 2. Dynamic online sampling function: The movable sampling mechanism, combined with the bidirectional opening and closing valve design, can complete material collection without interrupting the granulation process, and analyze the particle morphology and uniformity in real time through the built-in camera, significantly improving the efficiency of quality monitoring.

[0015] 3. Structural stability optimization: The first drive component adopts a screw-guide rod composite transmission mechanism, combined with a limit design, to ensure the accurate and reliable movement trajectory of the sampling frame; the second drive component uses a cylinder and guide rod to achieve rapid opening and closing of the valve, simplifying operation and reducing the risk of failure.

[0016] 4. Collaborative control of dust pollution: During the feeding stage, an upward-sloping spray pattern is adopted to effectively cover the dust-generating area during feeding; during the mixing stage, a directional downward spray is applied to suppress particle rolling and dust generation, forming a multi-angle dust suppression coverage and reducing the dust concentration in the workshop.

[0017] 5. Improved ease of maintenance: The modular water spray pipeline and split sampling mechanism design facilitate disassembly for cleaning or component replacement, reducing downtime for maintenance and ensuring long-term stable operation of the equipment. Attached Figure Description

[0034] A dust-proof lithium mica disc granulation device, the granulation device comprising:

[0035] Base 10;

[0036] The granulation disc 20 is rotatably mounted on the base 10, wherein the base 10 is equipped with a motor (not shown in the figure) for driving the granulation disc 20, and a support frame 11 passing above the granulation disc 20 is mounted on the base 10.

[0037] The feed inlet 30 is located above the granulation disc 20 and is used to vertically feed materials into the granulation disc 20.

[0038] The water spray pipe is installed on the support frame 11. The water spray pipe includes a feeding dust suppression spray pipe 411 and a stirring dust suppression spray pipe 421. Multiple feeding dust suppression spray pipes 411 and stirring dust suppression spray pipes 421 are arranged along the axial direction of the water spray pipe. The nozzle of each feeding dust suppression spray pipe 411 is inclined and faces the feed inlet 30. It is used to spray water when the device is feeding to reduce the dust generated during feeding. The nozzle of the stirring dust suppression spray pipe 421 is downward and faces the granulation disc 20. When the granulation disc 20 is rotating and granulating, the stirring dust suppression spray pipe 421 sprays water to reduce the dust generated during stirring.

[0039] As a first embodiment, such as Figure 8 As shown, two water spray pipes are installed on the support frame 11, namely the first water pipe 41 and the second water pipe 42. The first water pipe 41 is connected to the feeding dust suppression spray pipe 411; the second water pipe 42 is connected to the stirring dust suppression spray pipe 421, so that the operator can control the feeding dust suppression spray pipe 411 through the first water pipe 41 and the stirring dust suppression spray pipe 421 through the second water pipe 42. When feeding, the first water pipe 41 and the second water pipe 42 are turned on, and the feeding dust suppression spray pipe 411 and the stirring dust suppression spray pipe 421 spray water at the same time for preliminary dust suppression. When stirring, the dust is reduced, the first water pipe 41 can be turned off, and only the second water pipe 42 can be turned on, so that the stirring dust suppression spray pipe 421 can suppress the dust of the material in the granulation disc 20.

[0040] As a second embodiment, such as Figure 9As shown, two water spray pipes are installed on the support frame 11, namely a first water pipe 41 and a second water pipe 42. The first water pipe 41 is connected to the feeding dust suppression spray pipe 411; the second water pipe 42 is connected to the stirring dust suppression spray pipe 421. The water spray pipes include a first water pipe 41 and a second water pipe 42; the first water pipe 41 is connected to the feeding dust suppression spray pipe 411; the second water pipe 42 is connected to the stirring dust suppression spray pipe 421. The first water pipe 41 is installed on the outer wall of the feed inlet 30, and the feeding dust suppression spray pipe 411 faces the discharge outlet of the feed inlet 30, so that the operator can control the feeding dust suppression spray pipe 411 through the first water pipe 41 and control the stirring dust suppression spray pipe 421 through the second water pipe 42. When feeding, the first water pipe is turned on. Water is sprayed simultaneously from pipe 41 and second water pipe 42, feeding dust suppression spray pipe 411 and stirring dust suppression spray pipe 421 for initial dust suppression. When stirring, the dust is reduced, and the first water pipe 41 can be closed, and only the second water pipe 42 can be opened. The stirring dust suppression spray pipe 421 suppresses the dust in the granulation disc 20. Compared with the first embodiment, in the second embodiment, the feeding dust suppression spray pipe 411 is installed on the top and arranged around the feed inlet 30. Water is sprayed from top to bottom in a mist form through the spray pipe, which improves the dust suppression effect.

[0041] Based on further improvements to the above structure, the granulation device further includes a sampling mechanism 50;

[0042] Sampling facility 50 includes:

[0043] A sampling frame 51 is movably connected to the base 10. A sampling valve 511 is movably installed below the sampling frame 51, and a sampling port 512 is formed between the sampling valve 511 and the sampling frame 51. Figure 4 As shown, for example, the granulation disc 20 rotates clockwise, and the sampling port 512 is set to face upward. After the sampling port 512 is inserted into the granulation disc 20, the material in the granulation disc 20 will naturally enter the upward-facing sampling port 512.

[0044] Since the sampling valve 511 and the sampling frame 51 are movable, when the sampling valve 511 is closed, the sampling port 512 only has a front opening, such as... Figure 5 As shown on the right side, the sampling rack 51 enters the sampling state at this time. The sample falls into the sampling port 512 and will not escape. After the sampling valve 511 is opened, the side of the sampling port 512 opens. Since the sampling port 512 is set upward, the sample will fall out from the side opening. Figure 5 As shown on the left, the sampling rack 51 exits the sampling state at this time so that the sample falls back into the granulation disk 20;

[0045] The sampling mechanism 50 further includes a camera assembly 52, which is installed inside the sampling port 512 for capturing images of the sample entering the sampling port 512 to analyze the sample and check the granulation quality. The sample can be sampled without stopping the granulation disc 20.

[0046] Based on the above structure, the sampling mechanism 50 further includes a first driving component 60 for driving the sampling frame 51 to move along the height direction of the granulation disk 20, so that the sampling port 512 extends into or out of the granulation disk 20. Specifically, the first driving component 60 includes: a driving motor 61, mounted on the top of the sampling frame 51; and a lead screw 62, one end of which passes through the sampling frame 51 and is connected to the output end of the driving motor 61, and the other end is threadedly engaged with the protrusion 12 on the side of the base 10. The driving motor 61 drives the lead screw 62 to rotate, and the threaded engagement between the lead screw 62 and the protrusion 12 causes the sampling frame 51 to move along the height direction of the granulation disk 20. During sampling, the driving motor 61 rotates the lead screw 62, so that the sampling port 512 on the sampling frame 51 extends into the granulation disk 20. After sampling is completed, the driving motor 61 reverses the lead screw 62, so that the sampling port 512 on the sampling frame 51 is removed from the granulation disk 20.

[0047] Furthermore, a first guide rod 53 is installed on the sampling frame 51. The end of the first guide rod 53 away from the sampling frame 51 passes through the protrusion 12, and the first guide rod 53 is movably connected to the protrusion 12 to guide the sampling frame 51 to move so that it is not easy to deviate from its position. A limit plate is also installed at the end of the first guide rod that passes through the protrusion 12 to prevent the sampling frame 51 from detaching from the first guide rod.

[0048] The second drive assembly 70 is used to drive the sampling valve 511 so that the sampling port 512 enters and exits the sampling state, such as Figure 5 and Figure 6 As shown, the second drive assembly 70 includes: a connecting rod 71, which passes through the sampling frame 51 and is movably connected to the sampling frame 51, with one end extending out of the sampling frame 51 and fixed to the sampling valve 511; and a cylinder 72, which is installed on the top of the sampling frame 51, with its base end fixed to the top of the sampling frame 51 and its telescopic end extending into the sampling frame 51 and connected to the end of the connecting rod 71 away from the sampling valve 511. Since the sampling valve 511 only needs to be opened and closed in a fixed direction, there is no need for precise adjustment of its position. Therefore, the drive component for moving the sampling valve 511 is preferably the cylinder 72 to save manufacturing costs.

[0049] Furthermore, a second guide rod 54 is installed on the sampling valve 511. The end of the second guide rod 54 away from the sampling frame 51 passes through the sampling frame 51 and is equipped with a limit plate. The second guide rod 54 is movably connected to the sampling frame 51. The second guide rod 54 can limit the movement of the sampling valve 511 and cooperate with the cylinder 72 to open and close the sampling valve 511.
