Abstract
Description
Technical Field
[0001] This utility model relates to the field of rotary kiln technology, specifically to a rotary kiln mechanism for ceramsite production. Background Technology
[0002] A rotary kiln, also known as a rotary calcining kiln, is a core large-scale industrial piece of equipment widely used in the building materials, metallurgy, chemical, and environmental protection industries. Its function is to utilize rotation and high internal temperatures to calcine materials within the kiln, thereby producing finished minerals, such as ceramsite.
[0003] Currently, the rotation of a rotary kiln is supported by multiple roller sets. During the rotary kiln's rotation and calcination, the friction between the roller sets needs to be lubricated, otherwise it will affect the rotary kiln's rotation and calcination efficiency. However, the temperature around the rotary kiln during calcination is high, and manually adding lubricating oil poses a risk of injury. There is an urgent need to design a rotary kiln mechanism for ceramsite production to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a rotary kiln mechanism for ceramsite production to address the aforementioned shortcomings in the prior art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A rotary kiln mechanism for producing ceramsite includes a combustion chamber, a rotary kiln rotatably fitted to one side of the combustion chamber, a combustion cylinder corresponding to the rotary kiln disposed within the combustion chamber, a blower installed at one end of the combustion cylinder, a support frame installed at the bottom of the combustion chamber, a discharge port opened at the bottom of the combustion chamber, and a feed hopper installed at one end of the rotary kiln; multiple slide rails are fitted around the periphery of the rotary kiln, and a fixed frame is disposed around the periphery of the slide rails; two support rollers cooperating with the slide rails are rotatably fitted within the fixed frame, the two support rollers being symmetrically arranged on both sides of the bottom of the slide rails; an mounting plate is installed at the bottom of the fixed frame, a drive mechanism is disposed between the top of one of the mounting plates and the rotary kiln; an oil tank corresponding to the slide rail is disposed at the top of the fixed frame, a sealing plug is movably connected to the bottom of the oil tank, and fixing rods are installed on both sides of the sealing plug; both fixing rods are elastically fitted with the top of the inner wall of the fixed frame; and arc-shaped grooves corresponding to the fixing rods are opened on the slide rails.
[0007] Furthermore, a collection box is slidably fitted inside the support frame, cooling fans are installed on opposite sides of the inner wall of the support frame, and a waste heat flue gas exhaust pipe is provided at the top of the combustion chamber.
[0008] Furthermore, an igniter is installed at one end of the combustion cylinder, a feed pipe is provided at the top of the combustion cylinder, and a waste discharge port is provided at the bottom of the combustion cylinder.
[0009] Furthermore, a support bearing is installed on one side of the combustion chamber, and the rotary kiln is rotatably coupled to the support bearing.
[0010] Furthermore, an elastic telescopic rod is installed between the top of each of the two fixing rods and the top of the inner wall of the fixing frame. The two fixing rods are arranged symmetrically and are circular.
[0011] Furthermore, the drive mechanism includes a motor mounted on the top of one of the mounting plates, a gear ring sleeved on the periphery of the rotary kiln, and a gear mounted on the output end of the motor, the gear meshing with the gear ring.
[0012] Furthermore, one of the mounting plates is equipped with two support rods on its top, and a gear guard is installed on the top of the two support rods, with the gear ring and the gear located inside the gear guard.
[0013] In the above technical solution, the rotary kiln mechanism for ceramsite production provided by this utility model has the following beneficial effects:
[0014] By using a fixed rod, when it aligns with the arc-shaped groove on the slide rail, the fixed rod can elastically move downwards, causing the sealing plug to move out of the oil tank. This allows lubricating oil to be discharged from the oil tank onto the slide rail, reducing the risk of injury from manual lubrication. The arc-shaped groove also allows the slide rail to rotate as the rotary kiln moves, causing the fixed rod and sealing plug to periodically move downwards via elasticity to add lubricating oil. This allows for continuous use, requiring lubricating oil to be added to the oil tank only after calcination, saving manpower. Attached Figure Description

[0024] Reference Figure 2 In this embodiment, a collection box 16 is slidably fitted inside the support frame 5. Cooling fans 17 are installed on opposite sides of the inner wall of the support frame 5, and a waste heat exhaust pipe 18 is provided on the top of the combustion chamber 1. The collection box 16 can collect the finished product discharged from the combustion chamber 1, and the cooling fans 17 can cool the finished product in the collection box 16. The waste heat exhaust pipe 18 can recover and utilize the waste heat of the finished product.
[0025] Reference Figure 2 In this embodiment, an igniter 19 is installed at one end of the combustion cylinder 3, a feed pipe 20 is provided at the top of the combustion cylinder 3, and a waste discharge port is provided at the bottom of the combustion cylinder 3. Through the feed pipe 20, fuel can be delivered into the combustion cylinder 3, and the igniter 19 can ignite the fuel in the combustion cylinder 3.

[0026] Reference Figure 2 In this embodiment, a support bearing 21 is installed on one side of the combustion chamber 1, and the rotary kiln 2 is rotatably connected to the support bearing 21. The support bearing 21 supports the rotary kiln 2, allowing part of the rotary kiln 2 to enter the combustion chamber 1, and enabling the rotary kiln 2 to rotate and discharge material within the combustion chamber 1.
[0027] Reference Figure 3 In this embodiment, elastic telescopic rods 22 are installed between the top of the two fixing rods 14 and the top of the inner wall of the fixing frame 7. The two fixing rods 14 are symmetrically arranged and are circular. The elastic telescopic rods 22 can push the fixing rods 14 downward, and the circular shape of the fixing rods 14 can better fit the arc-shaped groove 15.
[0028] Reference Figure 4 The drive mechanism 10 in this embodiment includes a motor 23 mounted on the top of one of the mounting plates 9, a gear ring 24 sleeved around the rotary kiln 2, and a gear 25 mounted on the output end of the motor 23. The gear 25 meshes with the gear ring 24. The motor 23 drives the gear 25 to rotate, which in turn drives the gear ring 24 to rotate, which in turn drives the rotary kiln 2 to rotate and calcine.
[0029] Reference Figure 4 In this embodiment, one of the mounting plates 9 is equipped with two support rods 26 on its top. A gear protective cover 27 is installed at the top of the two support rods 26, and the gear ring 24 and gear 25 are located inside the gear protective cover 27.

[0030] Working principle: During operation, fuel is first added to the combustion chamber 3 for combustion. The blower 4 blows hot combustion gases into the rotary kiln 2, raising the temperature inside. Then, calcining raw materials are added through the feed hopper 11. The raw materials enter the rotary kiln 2 through the feed hopper 11. The drive mechanism 10 is activated to rotate the rotary kiln 2, causing the raw materials inside to rotate. The high temperature calcines the raw materials. The rotary kiln 2 is installed at an angle, and the raw materials gradually pass through the rotary kiln 2 to the combustion chamber 1, and then exit through the outlet at the bottom of the combustion chamber 1. The calcined ceramsite is discharged from the feed port. During the rotation of the rotary kiln 2, the rotary kiln 2 will drive the slide rail 6 to rotate. The two support rollers 8 in the fixed frame 7 will support the rotating slide rail 6. The rotation of the slide rail 6 will drive the arc groove 15 to rotate. When the arc groove 15 moves to the fixed rod 14, the fixed rod 14 will move downward due to the elastic force. The movement of the fixed rod 14 will drive the sealing plug 13 to move, so that the sealing plug 13 moves out of the bottom of the oil tank 12. At this time, the lubricating oil in the oil tank 12 will be discharged onto the slide rail 6 to lubricate the continuously rotating slide rail 6.
