Description

Technical Field

[0001] This utility model relates to the field of decomposition furnace technology, and in particular to an alkaline raw material decomposition furnace. Background Technology

[0002] A rotary kiln is a decomposition furnace that can decompose cement raw materials (mainly alkaline raw materials). In a rotary kiln, the decomposition of cement raw materials is based on thermochemical reactions. Alkaline raw materials are usually made by mixing limestone, clay, iron ore, etc. in a certain proportion. When the alkaline raw materials enter the rotary kiln, as the kiln rotates and the temperature rises, the raw materials are gradually heated into clinker and decomposed.

[0003] The above-mentioned and existing technologies have the following drawbacks: when caking alkaline raw materials are fed into the rotary kiln, the caking alkaline raw materials are difficult to be fully heated and decomposed, resulting in a large number of impurities in the decomposed clinker, which reduces the practicality of the rotary kiln.

[0004] Therefore, an alkaline raw material decomposition furnace is proposed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that caking alkaline raw materials are difficult to fully heat and decompose, resulting in a large number of impurities in the decomposed clinker and a decrease in the practicality of the rotary kiln. Therefore, an alkaline raw material decomposition furnace is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an alkaline raw material decomposition furnace, comprising a rotary kiln, wherein a feed hopper is fixedly connected to the feed end of the rotary kiln, a fixed plate is fixedly connected to the inner wall of the feed hopper, a guide rod is fixedly connected to the upper surface of the fixed plate, a triangular frame is slidably fitted onto the surface of the guide rod, the triangular frame is slidably connected to the feed hopper, and a screening plate is fixedly connected to the surface of the triangular frame.

[0007] The effect achieved by the above-mentioned components is as follows: when alkaline raw materials are decomposed by setting up a screening plate, the screening plate will screen the alkaline raw materials, and the caking alkaline raw materials will remain on the upper surface of the screening plate, thereby avoiding the situation where the caking alkaline raw materials cannot be fully heated and thus affecting the quality of the clinker produced, and improving the practicality of the rotary kiln.

[0008] Preferably, a motor is fixedly connected to the outer wall of the feed hopper, and a rotating plate is fixedly mounted on the output end of the motor through the feed hopper. A transmission rod is rotatably connected to the triangular frame relative to the position of the rotating plate.

[0009] The effect achieved by the above components is as follows: when the motor is turned on, the output end of the motor rotates, which drives the rotating plate to rotate. The transmission rod will cause the triangular frame to slide upward along the inner wall of the feed hopper due to compression. The sliding of the triangular frame along the arc surface of the guide rod will cause the screening plate to slide. When the rotating plate no longer compresses the transmission rod, the screening plate will slide downward due to gravity. Therefore, during the continuous operation of the motor, the screening plate can continuously shake in the vertical direction, thereby accelerating the passage speed of alkaline raw materials.

[0010] Preferably, the arc surface of the transmission rod is fixedly fitted with a rubber sleeve.

[0011] The effect achieved by the above components is that the rotating plate will contact the rubber sleeve on the arc surface of the transmission rod when it rotates, and the rubber sleeve can reduce the collision force between the rotating plate and the transmission rod.

[0012] Preferably, two electric push rods are fixedly mounted on the inner wall of the feed hopper, and a pressure plate is fixedly connected to the output end of the electric push rods.

[0013] The effect achieved by the above components is as follows: through the cooperation of components such as electric push rod and pressure plate, when the caking alkaline raw material is pushed upward by the screening plate, the pressure plate and screening plate will crush the alkaline raw material, thereby breaking the alkaline raw material into a suitable size, and also preventing the large accumulation of caking alkaline raw material from affecting the normal use of the screening plate.

[0014] Preferably, the pressure plate is inclined to the screening plate.

[0015] The effect achieved by the above components is that by tilting the pressure plate against the screening plate, alkaline raw materials of different sizes can be crushed by compression.

[0016] Preferably, a plurality of cone blocks are fixedly connected to the lower surface of the pressure plate.

[0017] The effect achieved by the above-mentioned components is that the cone blocks can better crush the hardened alkaline raw materials.

[0018] Preferably, a guide plate is fixedly connected to the feed hopper relative to the electric push rod.

[0019] The effect achieved by the above components is that the guide plate can guide the sliding position of the alkaline raw material, preventing the alkaline raw material from hitting the electric actuator and causing a decrease in the service life of the electric actuator.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] 1. In this utility model, by setting a screening plate, when decomposing alkaline raw materials, the screening plate will screen the alkaline raw materials, and the caking alkaline raw materials will remain on the upper surface of the screening plate, thereby avoiding the situation where the caking alkaline raw materials cannot be fully heated, thus affecting the quality of the clinker produced, and improving the practicality of the rotary kiln.

[0022] 2. In this utility model, through the cooperation of components such as electric push rod and pressure plate, when the caking alkaline raw material is pushed upward by the screening plate, the pressure plate and screening plate will crush the alkaline raw material, thereby breaking the alkaline raw material into a suitable size, and also avoiding the situation where the caking alkaline raw material accumulates in large quantities and affects the normal use of the screening plate.

[0028] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0030] like Figures 1-4As shown, this utility model provides an alkaline raw material decomposition furnace, including a rotary kiln 1. A feed hopper 2 is fixedly connected to the feed end of the rotary kiln 1. A fixing plate 3 is fixedly connected to the inner wall of the feed hopper 2. A guide rod 4 is fixedly connected to the upper surface of the fixing plate 3. A triangular frame 5 is slidably fitted onto the surface of the guide rod 4. The triangular frame 5 is slidably connected to the feed hopper 2. A screening plate 6 is fixedly connected to the surface of the triangular frame 5. A motor 7 is fixedly connected to the outer wall of the feed hopper 2. A rotating plate 8 is fixedly mounted on the output end of the motor 7, passing through the feed hopper 2. A transmission rod 9 is rotatably connected to the triangular frame 5 relative to the position of the rotating plate 8. When the motor 7 is turned on, the output end of the motor 7... The rotation will cause the rotating plate 8 to rotate, and the transmission rod 9 will cause the triangular frame 5 to slide upward along the inner wall of the feed hopper 2 due to compression. The sliding of the triangular frame 5 along the arc surface of the guide rod 4 will cause the screening plate 6 to slide. When the rotating plate 8 no longer compresses the transmission rod 9, the screening plate 6 will slide downward due to gravity. Therefore, during the continuous operation of the motor 7, the screening plate 6 can continuously vibrate in the vertical direction, thereby accelerating the passage speed of alkaline raw materials. The arc surface of the transmission rod 9 is fixedly covered with a rubber sleeve 10. When the rotating plate 8 rotates, it will contact the rubber sleeve 10 on the arc surface of the transmission rod 9. The rubber sleeve 10 can reduce the collision force between the rotating plate 8 and the transmission rod 9.

[0031] like Figures 2-4 As shown, two electric push rods 11 are fixedly mounted on the inner wall of the feed hopper 2. A pressure plate 12 is fixedly connected to the output end of the electric push rod 11. Through the cooperation of the electric push rod 11 and the pressure plate 12, when the caking alkaline raw material is pushed upward by the screening plate 6, the pressure plate 12 and the screening plate 6 will crush the alkaline raw material, thereby crushing the alkaline raw material into a suitable size. It can also prevent the large accumulation of caking alkaline raw material from affecting the normal use of the screening plate 6. The pressure plate 12 is inclined to the screening plate 6. By making the pressure plate 12 inclined to the screening plate 6, it can squeeze and crush caking alkaline raw materials of different sizes. Several cone blocks 13 are fixedly connected to the lower surface of the pressure plate 12. The cone blocks 13 can better crush the caking alkaline raw material. A guide plate 14 is fixedly connected to the position of the feed hopper 2 relative to the electric push rod 11. The guide plate 14 can guide the sliding position of the alkaline raw material and prevent the alkaline raw material from hitting the electric push rod 11, which would reduce the service life of the electric push rod 11.

[0032] The overall working principle is as follows: When alkaline raw materials need to be decomposed, they are fed into the feed hopper 2. At this time, the screening plate 6 will screen the alkaline raw materials, and the caking alkaline raw materials will remain on the upper surface of the screening plate 6, thus avoiding the situation where the caking alkaline raw materials cannot be fully heated, which would affect the quality of the clinker produced. At the same time, the guide plate 14 can guide the sliding position of the alkaline raw materials, preventing them from hitting the electric push rod 11 and reducing its service life. Then, the motor 7 is turned on, and the output end of the motor 7 rotates, which drives the rotating plate 8 to rotate. The rotating plate 8 will contact the rubber sleeve 10 on the arc surface of the transmission rod 9. The rubber sleeve 10 can reduce the collision force between the rotating plate 8 and the transmission rod 9. At the same time, the transmission rod 9 will cause the triangular frame 5 to slide upward along the inner wall of the feed hopper 2 due to compression. The sliding of the triangular frame 5 along the arc surface of the guide rod 4 will drive the screening plate 6 to slide. When the rotating plate 8 no longer compresses the transmission rod 9, The screening plate 6 slides downwards due to gravity. Therefore, during the continuous operation of the motor 7, the screening plate 6 can continuously vibrate in the vertical direction, thereby accelerating the passage speed of the alkaline raw material. At the same time, the caking alkaline raw material will slide downwards along the surface of the screening plate 6 and accumulate. Then, the electric push rod 11 is turned on, and the output end of the electric push rod 11 will drive the pressure plate 12 to move downwards. When the caking alkaline raw material is pushed upwards by the screening plate 6, the pressure plate 12 and the screening plate 6 will crush the alkaline raw material, thereby crushing the alkaline raw material into a suitable size. This can also prevent the large accumulation of caking alkaline raw material from affecting the normal use of the screening plate 6. The cone block 13 can better crush the caking alkaline raw material, and by tilting the pressure plate 12 towards the screening plate 6, it can squeeze and crush caking alkaline raw materials of different sizes. Afterwards, the alkaline raw material of suitable size will enter the rotary kiln 1 through the feed hopper 2, and the rotary kiln 1 will heat and decompose the alkaline raw material.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
