Description
Technical Field
[0001] This utility model relates to the field of magnesium-calcium-carbon brick technology, and in particular to a crushing device for magnesium-calcium-carbon bricks. Background Technology
[0002] Magnesia-calcium-carbon bricks are refractory products made primarily from dolomite sand, magnesia, and flake graphite. They are also used as linings for high-temperature kilns in the glass and ceramics industries, exhibiting excellent refractoriness and erosion resistance, effectively protecting the kiln walls from the corrosive effects of high-temperature gases and chemicals. While magnesia-calcium-carbon bricks are recyclable refractory materials, recycling requires crushing. However, existing crushing equipment presents several challenges in its operation.
[0003] Existing crushing equipment cannot effectively crush magnesia-calcium-carbon bricks due to their high overall hardness, resulting in poor overall crushing effect and low processing efficiency. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a crushing device for magnesium-calcium-carbon bricks.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A crushing device for magnesium-calcium-carbon bricks includes a first cylindrical shell, with a support leg welded to the bottom outer wall of the first cylindrical shell, and a discharge slot extending through the bottom of the first cylindrical shell. An arc-shaped screen is fixedly attached to the inner wall of the discharge slot, and a second cylindrical shell is hinged to one side of the top of the first cylindrical shell. Triangular turntables are rotatably mounted on the inner walls of both ends of the first cylindrical shell, and three equidistant connecting rods are fixed between the two triangular turntables. Positioning blocks are welded to the outer walls of the connecting rods, and fixed brackets are fixedly attached to the outer walls of the positioning blocks. A fixed cover is fixed to one side of the fixed bracket by screws, and a crushing ball is hinged to the bottom outer wall of the fixed bracket.
[0007] As a further improvement of this utility model: a guide plate is welded to the bottom outer wall of the first cylindrical shell, and the guide plate is located directly below the unloading trough.
[0008] As a further embodiment of this utility model: a first synchronous pulley is fixed to one outer wall of the triangular turntable, and a synchronous belt is engaged with the inner wall of the first synchronous pulley. A second synchronous pulley is engaged with the bottom of the synchronous belt, and a servo motor is connected to the axis of the second synchronous pulley.
[0009] As a further embodiment of this utility model: the inner wall of the top side of the second cylindrical shell is connected to a feeding groove along the inclined direction, and the inner wall of the bottom of the feeding groove is rotatably installed with rotating rollers distributed at equal intervals.
[0010] As a further improvement of this utility model: a connecting pipe is provided directly above the feeding trough, and the bottom inner wall of the connecting pipe is connected to spray heads that are evenly distributed, and a water inlet pipe is connected to one side inner wall of the connecting pipe.
[0011] As a further improvement of this utility model: there is a gap between the bottom outer wall of the crushing rod and the bottom inner wall of the arc-shaped screen, and the gap distance is 1-2 cm.
[0012] As a further improvement of this utility model: the servo motor is connected to a switch via a wire, and the switch is connected to an external power source via a wire.
[0013] Compared with the prior art, the present invention provides a crushing device for magnesium-calcium-carbon bricks, which has the following beneficial effects:
[0014] 1. The crushing device for magnesium-calcium-carbon bricks in this design places the magnesium-calcium-carbon bricks on top of a rotating roller shaft before crushing them, and uses gravity to roll them in. During the conveying process, water is continuously sprayed onto the magnesium-calcium-carbon bricks from above, causing them to crack and pulverize, thus reducing their strength and facilitating subsequent crushing.
[0015] 2. The crushing device for magnesium-calcium-carbon bricks in this design uses a servo motor to drive a triangular turntable to rotate continuously after the magnesium-calcium-carbon bricks crack and their strength decreases when water is poured on them. This drives the internal crushing rod to make circular motion, accelerating the impact force of the crushing rod. This can effectively crush the cracked magnesium-calcium-carbon bricks by knocking them down. The crushed particles will fall from the bottom of the arc-shaped screen to complete the crushing process.
[0016] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Example 1:
[0024] A crushing device for magnesium-calcium-carbon bricks, as described in this embodiment, Figure 1-4 As shown, it includes a first cylindrical shell 1, with a support leg 2 welded to the bottom outer wall of the first cylindrical shell 1, and a discharge slot 3 extending through the bottom of the first cylindrical shell 1. An arc-shaped screen 4 is fixedly attached to the inner wall of the discharge slot 3, and a second cylindrical shell 6 is hinged to one side of the top of the first cylindrical shell 1. Triangular turntables 7 are rotatably installed on the inner walls of both ends of the first cylindrical shell 1, and three equally spaced connecting rods 8 are fixed between the two triangular turntables 7. The outer walls of the connecting rods 8 are welded with equally spaced positioning blocks 9, and the outer walls of the positioning blocks 9 are fixedly attached to a fixing seat 10. A fixing cover 11 is fixed to one side of the fixing seat 10 by screws, and a crushing ball rod 12 is hinged to the outer wall of one side of the bottom of the fixing seat 10.
[0025] Before crushing the magnesium calcium carbon bricks, they are placed on top of the rotating roller 18 and rolled in by gravity. During the conveying process, the magnesium calcium carbon bricks are continuously sprayed with water by the spray nozzles 20 above, which causes the magnesium calcium carbon bricks to crack and pulverize, reducing their strength and making it easier to crush them later.
[0026] The bottom outer wall of the first cylindrical shell 1 is welded with a guide plate 5, and the guide plate 5 is located directly below the unloading trough 3. The outer wall of one side of the triangular turntable 7 is fixed with a first synchronous pulley 13, and the inner wall of the first synchronous pulley 13 is engaged with a synchronous belt 14. The bottom of the synchronous belt 14 is engaged with a second synchronous pulley 15, and a servo motor 16 is connected to the axis of the second synchronous pulley 15.
[0027] The inner wall of the top side of the second cylindrical shell 6 is connected to a feed trough 17 along the inclined direction, and rotating rollers 18 are rotatably installed on the inner wall of the bottom of the feed trough 17.
[0028] A connecting pipe 19 is provided directly above the feed trough 17, and the bottom inner wall of the connecting pipe 19 is connected to spray heads 20 that are evenly distributed, and a water inlet pipe 21 is connected to one side inner wall of the connecting pipe 19.
[0029] After the strength of the magnesium-calcium-carbon bricks decreases due to water cracking, the servo motor 16 drives the triangular turntable 7 to rotate continuously, thereby driving the internal crushing rod 12 to make circular motion, accelerating the impact force of the crushing rod 12, which can effectively crush the cracked magnesium-calcium-carbon bricks. The qualified crushed particles will fall from the bottom of the arc-shaped screen 4 to complete the crushing.
[0030] In this embodiment, the crushing device is first assembled. After assembly, it is connected to an external power source for trial operation. After operation, the water inlet pipe 21 is connected to an external water pump to supply water, so the spray head 20 will continuously spray water. Then, the magnesium calcium carbon bricks to be crushed are placed on the top of the feed trough 17. The rotating roller 18, combined with gravity, allows the magnesium calcium carbon bricks to roll and be conveyed. Due to the continuous spraying of water from the top, the magnesium calcium carbon bricks will crack and pulverize when they come into contact with water, reducing their strength. After the cracked magnesium calcium carbon bricks enter the cylindrical shell, the servo motor 16 drives the triangular turntable 7 to rotate continuously, which in turn drives the crushing ball rod 12 to rotate continuously. When it comes into contact with the magnesium calcium carbon bricks, it will strike the magnesium calcium carbon bricks to crush them. As the crushing ball rod 12 strikes continuously, it is fully crushed. The qualified crushed particles fall from the bottom of the arc screen 4.
[0031] Example 2:
[0032] A crushing device for magnesium-calcium-carbon bricks, such as Figure 1-4 As shown, this embodiment makes the following additions based on embodiment 1: there is a gap between the bottom outer wall of the crushing rod 12 and the bottom inner wall of the arc-shaped screen 4, and the gap distance is 1-2 cm; the servo motor 16 is connected to a switch through a wire, and the switch is connected to an external power source through a wire.
[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
