Description

Technical Field

[0001] This invention relates to the field of lithium mineral processing, and more particularly to an automated controlled lithium ore roasting apparatus. Background Technology

[0002] Lithium mica roasting is an important pretreatment process for lithium extraction. It is mainly used to release soluble lithium compounds from lepidolite (a lithium-containing aluminosilicate mineral) so that lithium can be recovered through subsequent leaching, precipitation and other steps. After the lithium mineral is roasted, it is necessary to conduct real-time inspection and maintenance of the inside of the kiln and kiln head. Because a lot of dust and debris remain inside the kiln and kiln head, these dust and debris are trapped in the gaps between the kiln and kiln head and are difficult to be carried away during discharge. As a result, when the kiln head is manually removed from the kiln, a large amount of dust and debris falls out from the gaps between the kiln and kiln head, causing significant pollution to the surrounding environment.

[0008] Furthermore, it also includes a sealing ring; a sealing ring is slidably connected inside the conveying trough.

[0009] Furthermore, the curved panel uses heat-insulating material.

[0010] Furthermore, the inner wall of the discharge ring is truncated cone-shaped, and the diameter of the inner wall of the discharge ring on the side away from the cylinder is larger than the diameter on the side closer to the cylinder.

[0011] Furthermore, it also includes round rods and scrapers; several round rods are slidably connected to the kiln tail, and the round rods are slidably connected to the kiln head, and the round rods are made of high-temperature resistant alloy steel; each round rod is fixedly connected to a scraper, and the scraper is in contact with the inner wall of the cylinder, and the scraper is made of high-temperature resistant alloy steel.

[0015] During normal lithium ore discharge, the plug blocks close the circular hole under the elastic force of spring rod I, preventing dust and debris from entering the connecting groove and thus protecting solenoid valve I. When it is necessary to clean the gap between the cylinder and the kiln head, the air in the annular groove first enters the connecting groove through the open solenoid valve I, then pushes the plug blocks outward, stretches spring rod I, and opens the circular hole, allowing airflow to be ejected through the circular hole into the gap between the cylinder and the kiln head.

[0016] By controlling the motor of the power mechanism to start, the output shaft of the motor drives the gear to rotate, and the gear drives the gear ring and the kiln head to rotate, causing the kiln head to rotate 180 degrees until the collection pipe is facing downward. Then, the driver is controlled again to drive the cylinder to rotate, so that the cylinder and the scraper produce relative motion. The scraper then thoroughly scrapes off the remaining material and rings on the inner wall of the cylinder. The scraped-off material and rings and other waste are conveyed to the collection pipe for separate collection as the cylinder rotates. Attached Figure Description

[0022] It also includes a spring rod I 1010 and a plug 1011; the discharge ring 103 has a connecting groove 33, and the connecting groove 33 is connected to the solenoid valve I 109; the discharge ring 103 has a number of annularly distributed circular holes 34, and the circular holes 34 are connected to the connecting groove 33; the discharge ring 103 is fixedly connected to a number of spring rods I 1010, and the spring rods I 1010 are located in the connecting groove 33; each spring rod I 1010 has a plug 1011 fixedly connected to its telescopic end, and the plug 1011 is located in the corresponding circular hole 34.

[0024] It also includes a sealing ring 1013; the sealing ring 1013 is slidably connected inside the conveying groove 32.

[0025] Curved panel with 105 heat insulation material.

[0026] The inner wall of the discharge ring 103 is shaped like a frustum. The diameter of the inner wall of the discharge ring 103 on the side away from the cylinder 7 is larger than the diameter on the side closer to the cylinder 7. This guides the high-temperature material to the kiln head 101 side, allowing the high-temperature material to flow to the discharge pipe 102 under its own gravity. This reduces the residence time of the high-temperature material on the inner wall of the discharge ring 103, thereby reducing the phenomenon of high-temperature material adhering to the inner wall of the discharge ring 103.

[0027] In operation, the operator first controls the burner 9 to spray high-temperature flames and hot airflow into the cylinder 7 to heat the interior of the cylinder 7. Simultaneously, the external pump draws the hot airflow from inside the cylinder 7 through the exhaust pipe 5, causing the hot airflow to flow from the kiln head 101 to the kiln tail 3. Next, the motor of the driver 6 is started, and the motor output shaft drives the gear to rotate. The gear drives the gear ring and the cylinder 7 to rotate. Then, the operator manually pours a mixture of lepidolite minerals and additives (sulfates, etc.) into the rotating cylinder 7 through the feed pipe 4. Because the cylinder 7 is inclined, the material, under its own gravity and in conjunction with the rotation of the cylinder 7, continuously flows from the cylinder 7... The material flows from the kiln tail 3 to the kiln head 101. During this flow, the material comes into contact with the high-temperature hot airflow and is heated, resulting in a chemical reaction. The high-temperature material generated inside the cylinder 7 eventually falls from the discharge ring 103 to the discharge pipe 102 for collection, while the generated exhaust gas is drawn away by the exhaust pipe 5. Because the burner 9 is located on one side of the kiln head 101, the temperature is highest at the end of the cylinder 7 closest to the kiln head 101. This causes the material to easily melt and adhere to the inner wall of the cylinder 7 when passing through this end. As the cylinder 7 rotates, it forms a ring-shaped blockage. Therefore, a discharge ring 103 is installed at the end of the cylinder 7 closest to the kiln head 101. The discharge ring 103 rotates synchronously with the cylinder 7. When the material flows from inside the cylinder 7 to the discharge ring 103 where the temperature is highest, the electric push rod 104 drives the arc plate 105 and the hammer ball 106 to move vertically back and forth, causing the hammer ball 106 to repeatedly hammer the outer wall of the annular groove 31, thereby causing the discharge ring 103 to vibrate continuously. This reduces the phenomenon of high-temperature material adhering to the inner wall of the discharge ring 103 and causing blockage. After the lithium mineral roasting is completed, when it is necessary to perform real-time inspection and maintenance on the inside of the cylinder 7 and the kiln head 101, a lot of dust and debris will remain inside the cylinder 7 and the kiln head 101. These dust and debris are mixed in with the cylinder 7 The dust and debris inside the gap between the kiln head 101 and the discharge pipe 102 are difficult to carry away. As a result, when the kiln head 101 is removed from the end of the cylinder 7, a large amount of dust and debris falls out from the gap between the cylinder 7 and the kiln head 101, causing significant pollution to the surrounding environment. Therefore, when conducting real-time inspection and maintenance of the interior of the cylinder 7 and the kiln head 101, the cleaning components are controlled to clean the dust and debris remaining in the gap between the cylinder 7 and the kiln head 101 first, so as to avoid a large amount of dust and debris falling out from the gap between the cylinder 7 and the kiln head 101 when the kiln head 101 is removed from the end of the cylinder 7, causing significant pollution to the surrounding environment.

[0028] The steps for cleaning the components are as follows: First, control the electric push rod 104 to move the arc plate 105 and the hammer ball 106 downwards until the arc plate 105 and the hammer ball 106 are disengaged from the notch 11. Then, the electric sliding seat II 8 moves the burner 9, the kiln head 101, and its connected components away from the discharge ring 103. The kiln head 101 moves the connecting pipe 1014, causing the connecting pipe 1014 and the connector 1015 to separate. The kiln head 101 moves the folding ring 1012, so that the folding ring 1012 unfolds and completely covers the annular groove 31. Figure 6 As shown, next, the solenoid valve I 109 is opened, and then the electric push rod 104 drives the arc plate 105 and the hammer ball 106 to move vertically back and forth, so that the hammer ball 106 reciprocates and hammers the folding ring 1012. The folding ring 1012 undergoes adaptive deformation, forcing the air in the annular groove 31 into the gap between the cylinder 7 and the kiln head 101 through the opened solenoid valve I 109. Outside air continuously enters the annular groove 31 through the one-way valve in the hollow tube 107, so that the air in the annular groove 31 is continuously ejected from the solenoid valve I 109 into the cylinder 7 and the kiln head 101. The gap between the kiln head 101 and the cylinder 7 is pre-cleaned to remove residual dust and debris. The cleaned dust and debris are then drawn away by the discharge pipe 102 to prevent a large amount of dust and debris from falling out of the gap between the cylinder 7 and the kiln head 101 when the kiln head 101 is disassembled from the end of the cylinder 7, thus avoiding significant environmental pollution. After cleaning, the folding ring 1012 is removed from the kiln head 101 to completely separate the cylinder 7 and the kiln head 101, facilitating subsequent manual inspection and maintenance of the cylinder 7 and the kiln head 101.

[0029] Considering that the high-temperature lithium ore flowing from the discharge ring 103 into the discharge pipe 102 will contaminate the solenoid valve I109, in order to solve this problem, during normal lithium ore discharge, the plug 1011 closes the circular hole 34 under the elastic force of the spring rod I1010 to prevent dust and debris from entering the connecting groove 33, thereby protecting the solenoid valve I109. When it is necessary to clean the gap between the cylinder 7 and the kiln head 101, the air in the annular groove 31 enters the connecting groove 33 from the open solenoid valve I109, and then pushes the plug 1011 outward, the spring rod I1010 is stretched, and then the circular hole 34 is opened, and the airflow can be sprayed out through the circular hole 34 to the gap between the cylinder 7 and the kiln head 101.

[0030] During normal roasting of lithium ore, the electric push rod 104 drives the arc plate 105 and the hammer ball 106 to move vertically back and forth. When the hammer ball 106 hammers the discharge ring 103, the arc plate 105 moves back and forth within the notch 11, so that the arc plate 105 and the annular groove 31 form a relatively closed annular cavity. At this time, the air in the annular groove 31 is at a high temperature due to the heat transfer from the discharge ring 103. At this time, the control solenoid valve II 108 is opened and the control solenoid valve I 109 is closed. When the arc plate 105 reciprocates to squeeze the high temperature air in the annular groove 31, the high temperature air enters the conveying groove 32 through the solenoid valve II 108, then enters the connecting pipe 1014 from the conveying groove 32, and finally enters the burner 9, thereby preheating the combustion air of the burner 9 and improving the combustion efficiency of the burner 9.

[0031] At the same time, when high-temperature air enters the conveying trough 32 through the solenoid valve II 108, the high-temperature air compresses the sealing ring 1013, causing the sealing ring 1013 to press tightly against the kiln head 101, thereby enhancing the sealing between the kiln head 101 and the discharge ring 103.

[0032] In low-temperature environments, such as winter, the initial heating of the cylinder 7 by the burner 9 to the working temperature is relatively energy-intensive. Therefore, the electric push rod 104 is first controlled to drive the arc plate 105 and the hammer ball 106, so that the arc plate 105 closes the notch 11. Then, the arc plate 105, which is made of heat-insulating material, isolates the annular groove 31 from the outside cold air, reduces the heat exchange rate between the cold air and the outside of the discharge ring 103, and accelerates the heating rate of the discharge ring 103 and the cylinder 7.

[0033] Example 2, based on Example 1, such as Figures 1-3 As shown, it also includes a round rod 201 and a scraper 202; the kiln tail 3 is slidably connected to two round rods 201, and the round rods 201 are slidably connected to the kiln head 101, and the round rods 201 are made of high temperature resistant alloy steel; each round rod 201 is fixedly connected to a scraper 202, and the scraper 202 is in contact with the inner wall of the cylinder 7, and the scraper 202 is made of high temperature resistant alloy steel.

[0034] It also includes a guide plate 203; each scraper 202 is fixedly connected with several inclined guide plates 203.

[0035] It also includes a collection pipe 204 and a power mechanism 205; the collection pipe 204 is fixedly connected to the kiln head 101 and the collection pipe 204 is located above the discharge pipe 102; the electric sliding seat I2 is connected to the power mechanism 205, and the power mechanism 205 includes a motor fixedly connected to the electric sliding seat I2, a gear on the motor output shaft, and a gear ring fixedly connected to the kiln head 101.

[0036] Considering that lithium ore and additives partially melt at high temperatures and adhere to the inner wall of cylinder 7, long-term use will result in material buildup and ring formation on the inner wall of cylinder 7, leading to increased airflow resistance and reduced heat transfer efficiency. To solve this problem, a round rod 201 and a scraper 202 are installed inside cylinder 7. When cylinder 7 rotates to transport lithium ore, it generates relative movement with the round rod 201 and the scraper 202, thereby allowing the scraper 202 to scrape off the material buildup and ring formation on the inner wall of cylinder 7, reducing the amount of material buildup and ring formation on the inner wall of cylinder 7.

[0037] Furthermore, by setting an inclined guide plate 203 on the scraper 202, part of the airflow flowing towards the kiln tail 3 is guided to the inner wall of the cylinder 7, thereby blowing the material adhering to the inner wall of the cylinder 7, causing the material flowing on the inner wall of the cylinder 7 to gather at the bottom of the inner wall of the cylinder 7, so that the material is heated evenly, and at the same time, the height of the material on the inner wall of the cylinder 7 is reduced, reducing the amount of material carried away by the airflow.

[0038] During the material roasting process, material residue and ring formation continue to occur, and scraper 202 cannot completely remove the residue and ring formation on the inner wall of cylinder 7. Therefore, after the lithium mineral roasting is completed, a small amount of residue and ring formation will remain on the inner wall of cylinder 7. After all the material has flowed into the discharge pipe 102, the driver 6 is first controlled to stop rotating cylinder 7. Then, the electric push rod 104 is controlled to move the arc plate 105 and hammer ball 106 downward, causing the arc plate 105 and hammer ball 106 to detach from the kiln head 101. Then, the power is controlled... The motor of mechanism 205 starts, and the output shaft of the motor drives the gear to rotate. The gear drives the gear ring and the kiln head 101 to rotate, causing the kiln head 101 to rotate 180 degrees until the collection pipe 204 faces downward. Then, the driver 6 is controlled again to drive the cylinder 7 to rotate, so that the cylinder 7 and the scraper 202 generate relative movement. The scraper 202 then thoroughly scrapes off the remaining hanging material and rings on the inner wall of the cylinder 7. The scraped hanging material and rings and other waste materials are conveyed to the collection pipe 204 for separate collection as the cylinder 7 rotates.
