Description

Technical Field

[0001] This utility model relates to the field of refractory material production technology, specifically to a refractory material cooling device for an incinerator. Background Technology

[0002] Some refractory materials require high-temperature forming during processing, and then need to be rapidly cooled after high-temperature forming. Rapid cooling can prevent certain minerals in the refractory material (such as β-C2S) from undergoing unfavorable phase transformations (such as conversion to γ-C2S) at high temperatures, thereby maintaining the stability and performance of the material. Furthermore, rapid cooling can reduce the accumulation of thermal stress in the refractory material at high temperatures, avoid cracking or spalling caused by temperature fluctuations, extend the service life of the material, and refine the grain structure, thereby improving the mechanical strength and erosion resistance of the refractory material, especially in high-temperature and chemically corrosive environments.

[0003] Current cooling equipment is energy-intensive and its cooling effect is still not ideal, making it difficult to implement in existing refractory material processing production lines. Therefore, a new type of refractory material cooling equipment is needed to meet the cooling requirements of refractory materials. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a refractory material cooling device for incinerators.

[0005] The technical solution of this utility model is: a refractory material cooling device for an incinerator, including a support frame and a cylindrical shell rotatably mounted on the support frame and open at both ends. A conveyor belt for placing refractory material is provided at the inner axis position of the cylindrical shell. Several baffles that fit the inner wall of the cylindrical shell are evenly spaced on the conveyor belt. An arc-shaped guide groove is provided on the inner wall of the cylindrical shell, and a guide column that slides and engages with the arc-shaped guide groove on the baffle to drive the cylindrical shell to rotate is provided. A ring-shaped cold air box is mounted on the support frame. The cold air box is rotatably sleeved on the cylindrical shell. Several air inlets for air intake of the cold air box are provided circumferentially on the cylindrical shell.

[0006] Furthermore, the conveyor belt has several ventilation holes.

[0007] Note: By setting ventilation holes on the conveyor belt, the refractory material placed on one side of the conveyor belt can be cooled quickly, thereby improving the cooling efficiency of the refractory material.

[0008] Furthermore, the baffle is provided with several air guides, all of which are inclined at 10~30° toward the conveyor belt side.

[0009] Explanation: The movement of the baffle can improve the airflow in the cooling duct and guide a large amount of it to the refractory material placed on the conveyor belt. Furthermore, since the conveyor belt has ventilation holes, air can be discharged from the guide vents generated by the movement of the baffle in both the upper and lower halves of the cylindrical shell, thereby further improving the cooling effect of the refractory material.

[0010] Furthermore, the guide post is provided with ball bearings, and the arc-shaped guide groove is provided with an oil groove.

[0011] Explanation: The use of ball bearings and oil grooves can further reduce the friction coefficient between the guide column and the arc-shaped guide groove, thereby improving the efficiency of the guide column and the arc-shaped guide groove in driving the rotation of the cylindrical shell, making the conveyor belt move more smoothly.

[0012] Furthermore, the arc-shaped guide grooves on both sides of the annular end faces of the cylindrical shell have arc-shaped chamfers on both sides.

[0013] Explanation: The curved chamfer allows the guide post to connect more smoothly with the curved guide groove, thereby enabling the guide post to drive the cylindrical shell.

[0014] The beneficial effects of this utility model are: This invention utilizes a cooling duct constructed from a cylindrical shell to cool refractory materials. As the refractory material moves along the conveyor belt, it drives the cylindrical shell to rotate, thereby delivering cold air into the cylindrical shell from multiple angles through the air inlet. Furthermore, the rotation of the cylindrical shell creates a swirling flow within the cooling duct, significantly improving the cooling effect of the cold air on the refractory material. At the same time, the external supply of cold air greatly optimizes the equipment's maintenance efficiency and facilitates repair and maintenance. Attached Figure Description

Detailed Implementation

[0016] The present invention will now be described in more detail with reference to specific embodiments, so as to better demonstrate the advantages of the present invention.

[0017] Example 1: As Figures 1-5 As shown, a refractory material cooling device for an incinerator includes a support 1 and a cylindrical housing 2 rotatably mounted on the support 1 and open at both ends. The support 1 is as follows: Figure 1 As shown, the structure consists of vertical frames on both sides for fixing the conveyor belt 3 and horizontal plates for setting up rotating rings and cold air boxes 5. The cylindrical shell 2 is rotatably connected to two rotating rings on the horizontal plates. A conveyor belt 3 for placing refractory materials is provided at the inner axis position of the cylindrical shell 2. Several baffles 4 that fit the inner wall of the cylindrical shell 2 are evenly spaced on the conveyor belt 3. It should be noted that the belt body of the conveyor belt 3 is made of heat-resistant and fire-resistant material. The baffles 4 are slidably set on the frame of the conveyor belt 3 and fixed to the conveyor belt 3. The conveyor belt 3 provides the driving force for moving around the frame, and the frame provides the support for rotating the cylindrical shell 2. The support is provided, and the drive motor of the conveyor belt 3 is set on the frame to drive the roller of the conveyor belt 3 to rotate and drive the belt to move. The inner wall of the cylindrical shell 2 is provided with an arc-shaped guide groove 21, and the baffle 4 is provided with a guide post 41 that slides and engages with the arc-shaped guide groove 21 to drive the cylindrical shell 2 to rotate. The horizontal plate of the bracket 1 is provided with a ring-shaped cold air box 5. The cold air box 5 is a cold air supply module consisting of a commercially available refrigerator and a fan, and cold air is delivered into the cylindrical shell 2 through the ring-shaped air distribution channel. The cold air box 5 is rotatably sleeved on the cylindrical shell 2. The cylindrical shell 2 is provided with several air inlets for the cold air box 5 to enter the air in the circumferential direction.

[0018] The above-mentioned cooling equipment is used as follows: refractory material is placed on the conveyor belt 3 between the two baffles 4, and then the conveyor belt 3 is started to transport the refractory material to the cooling air duct formed by the cylindrical shell 2. Under the action of the cold air box 5, cold air is introduced into the cylindrical shell 2 through the air inlet by a commercially available blower. During the movement of the conveyor belt 3, the baffle 4 moves along the conveyor belt 3. When the baffle 4 moves to the lower half of the cylindrical housing 2, the guide post 41 enters the arc-shaped guide groove 21. The cylindrical housing 2 rotates due to the cooperation between the arc-shaped guide groove 21 and the guide post 41. During this period, the rotation of the cylindrical shell 2 can generate an additional flow effect at the air inlet of the cylindrical shell 2, thereby improving the cooling effect of the cooling air duct on the refractory material.

[0019] Example 2: This example differs from Example 1 in that, as Figure 6 As shown, the conveyor belt 3 has several ventilation holes; the baffle 4 is provided with several air guides 42, and the air guides 42 are all inclined to one side of the conveyor belt 3 at 10~30°.

[0020] The above-mentioned cooling equipment is used as follows: Based on the usage method of Example 1, during the movement of the baffle 4, the cold air can generate a transverse wind through the air guide 42 and be directed toward the refractory material, thereby further improving the cooling effect of the cooling air duct on the refractory material.

[0021] Example 3: The difference between this example and Example 1 is that the guide post 41 is provided with ball bearings, and the arc-shaped guide groove 21 is provided with an oil groove, which is used to fill commercially available lubricating oil, etc.

[0022] The above-mentioned cooling device is used as follows: Based on the usage method of Example 1, the guide column 41 can move more smoothly in the arc-shaped guide groove 21 through the ball bearings and oil groove.

[0023] Example 4: The difference between this example and Example 1 is that the arc-shaped guide grooves 21 on both sides of the annular end faces of the cylindrical shell 2 have arc-shaped chamfers on both sides.

[0024] The above-mentioned cooling equipment is used as follows: Based on the usage method of Example 1, the arc chamfer can make the guide post 41 and the arc guide groove 21 more accurately dock.
