Description

Technical Field

[0001] This utility model relates to the field of ceramsite sand production technology, and in particular to a material separation device for a rotary kiln of ceramsite sand. Background Technology

[0002] Expanded clay aggregate (ECA) is made from various raw materials such as clay, slate, shale, coal gangue, and industrial solid waste through ceramic sintering. It is generally used to replace crushed stone and pebbles in concrete. ECA sand has many advantages, including low density, excellent thermal insulation, excellent impermeability, excellent resistance to alkali-aggregate reactivity, low water absorption, and good frost resistance and durability.

[0003] In the production process of ceramsite sand, the rotary kiln is an important piece of equipment. As a key part of the rotary kiln system, the flue chamber mainly connects the rotary kiln and the decomposition furnace, realizing gas-solid separation and material conveying. Existing flue chamber material separation devices for ceramsite sand rotary kilns generally suffer from low separation efficiency. A large amount of unreacted material is discharged with the flue gas, which not only wastes materials but also increases the burden of subsequent waste gas treatment.

[0004] Therefore, it is necessary to provide a material separation device for the smoke chamber of a rotary kiln for ceramsite sand to solve the above-mentioned technical problems. Utility Model Content

[0005] This utility model provides a material separation device for the smoke chamber of a rotary kiln for ceramsite sand, which solves the problems in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides a material separation device for the flue gas chamber of a rotary kiln for ceramsite sand, comprising a cyclone separator body. A spiral air conveying chamber is formed inside the upper part of the cyclone separator body. An air inlet pipe is provided on the outer surface of the cyclone separator body, and the air inlet pipe is connected to the spiral air conveying chamber. An exhaust pipe is movably installed inside the cyclone separator body, and a strip-shaped hole is formed through the surface of the exhaust pipe. A filter screen is provided on the surface of the strip-shaped hole. The coordinated use of the cyclone separator body, exhaust pipe, strip-shaped hole, and filter screen facilitates the separation of materials. The separation process involves connecting the inlet pipe of the cyclone separator body to the outlet of the rotary kiln flue gas chamber during operation. This allows gas containing solids to enter the cyclone separator body and then be conveyed through the spiral air conveying chamber. Centrifugal force is used to separate large particles from the flue gas. The separated material falls into the collection hopper below through the second drain port at the bottom, while the gas enters the exhaust pipe through the strip-shaped holes and is then exhausted through the exhaust pipe. At the same time, a filter screen is installed on the surface of the strip-shaped holes to facilitate further separation of solids and gas. This method is simple to operate and facilitates the separation of materials.

[0007] Preferably, a collection hopper is provided on the bottom surface of the cyclone separator body via a fixing rod, and a second drain outlet is provided at the bottom of the cyclone separator body. The second drain outlet is located inside the collection hopper. By providing the collection hopper, it is convenient to recycle solid materials.

[0008] Preferably, a drive motor is installed on the bottom surface of the collection hopper. The output end of the drive motor extends through the surface of the collection hopper into the interior of the cyclone separator body and is fixed to the bottom surface of the exhaust pipe. A connecting rod is provided on the circumferential side of the exhaust pipe. A cleaning rod is provided at one end of the connecting rod. A wire brush is provided on the surface of the cleaning rod. The wire brush contacts the inner wall of the cyclone separator body. By using the drive motor, exhaust pipe, connecting rod, cleaning rod, and wire brush in coordination, when the cyclone separator body is working, the drive motor is started. It should be noted that the rotation direction of the drive motor is the same as the rotation direction of the gas. Then, the drive motor drives the cleaning rod to rotate through the exhaust pipe, so that the cleaning rod drives the wire brush to clean the inner wall of the cyclone separator body, thereby preventing solid particles from adsorbing onto the inner wall of the cyclone separator body and facilitating the smooth discharge of solid materials.

[0009] Preferably, multiple strip-shaped holes are provided, and the multiple strip-shaped holes are equally spaced around the periphery of the exhaust pipe. By providing multiple strip-shaped holes, it is convenient to transport and discharge gas.

[0010] Preferably, a vibrator is installed on the bottom surface of the collecting hopper. By setting the vibrator, the discharge efficiency of the collecting hopper can be improved.

[0011] Preferably, a first drain outlet is provided below the surface of the collecting hopper, and a sealing cap is adapted to the first drain outlet. By providing the first drain outlet, it is convenient to discharge the impurities collected inside the collecting hopper.

[0012] Preferably, a controller is installed on the outer surface of the cyclone separator body, which facilitates the control of the electrical components inside the equipment.

[0013] Compared with related technologies, the material separation device for the flue chamber of a rotary kiln for ceramsite sand provided by this utility model has the following beneficial effects:

[0014] Compared with existing technologies, the material separation device for the flue gas chamber of a rotary kiln for ceramsite sand facilitates material separation through the coordinated use of a cyclone separator body, exhaust pipe, strip-shaped holes, and filter screen. During operation, the air inlet pipe of the cyclone separator body is connected to the outlet of the rotary kiln flue gas chamber, allowing gas containing solids to enter the cyclone separator body. After being conveyed by the spiral air conveying chamber, centrifugal force separates large particles from the flue gas. The separated material falls into the collection hopper below through the second drain port at the bottom, while the gas enters the exhaust pipe through the strip-shaped holes and is then discharged through the exhaust pipe. Yes, a filter screen is also provided on the surface of the strip-shaped holes to facilitate further separation of solid and gas. This method is simple to operate and facilitates the separation of materials. By setting up a drive motor, exhaust pipe, connecting rod, cleaning rod, and wire brush in cooperation, when the main body of the cyclone separator is working, the drive motor is started. It should be noted that the rotation direction of the drive motor is the same as the rotation direction of the gas. Then, the drive motor drives the cleaning rod to rotate through the exhaust pipe, so that the cleaning rod drives the wire brush to clean the inner wall of the cyclone separator, thereby preventing solid particles from adsorbing onto the inner wall of the cyclone separator and facilitating the smooth discharge of solid materials.
