Abstract
Description
Technical Field
[0001] This utility model relates to the field of feeding machine technology, and in particular to a feeding machine for autoclaved aerated concrete blocks. Background Technology
[0002] Autoclaved aerated concrete (AAC) blocks are a new type of building material that is lightweight, porous, has good thermal insulation and fire resistance, and is also environmentally friendly. Like other concretes, AAC blocks are composed of several materials. During the production and processing, the mixed raw materials are fed through a feeding machine and finally shaped.
[0003] The existing patent CN202221854285.1 points out that the existing quantitative feeder lacks the function of crushing, and cannot crush the agglomerated materials, which easily leads to agglomeration and blockage of the machine. Furthermore, the raw materials after mixing are prone to incomplete discharge, which affects the quality of cement production in the later stage. Based on this, a quantitative feeder for cement production is proposed. The same problem also appears in the raw materials of autoclaved aerated concrete blocks.
[0004] However, it only uses crushing rollers to break up agglomerated materials, which cannot effectively crush the agglomerated materials. After crushing, there are still some broken materials. The crushing effect needs to be improved, which will affect the feeding quality of the raw materials for autoclaved aerated concrete blocks. Therefore, it is necessary to design a feeder for autoclaved aerated concrete blocks to solve the above problems.
[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood through the specific circumstances.
[0030] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0031] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a feeder for autoclaved aerated concrete blocks, comprising:
[0032] The feeder body 1 is equipped with a material processing cylinder 2, which is equipped with a material crushing mechanism. It should be noted that the material crushing mechanism can efficiently crush the raw materials of autoclaved aerated concrete blocks, ensuring the crushing effect of the raw materials and the feeding quality of the raw materials of autoclaved aerated concrete blocks.
[0033] The material crushing mechanism includes a material distribution pipe 3, a power motor 5, a rotating shaft 6, crushing blades 7, a rotating seat 8, a crushing and grinding seat 9, a first crushing blade 10, a second crushing blade 11, and a grinding head 12;
[0034] The feed pipe 3 is fixedly installed on the material processing cylinder 2. The power motor 5 is fixedly installed on the top of the material processing cylinder 2. The output end of the power motor 5 is fixedly connected to the rotating shaft 6. The crushing blade 7 is fixedly installed on the outside of the rotating shaft 6. The rotating seat 8 is fixedly connected to the bottom of the rotating shaft 6. The crushing and grinding seat 9 is fixedly installed inside the material processing cylinder 2. The first crushing blade 10 is fixedly installed on the outside of the rotating seat 8. The second crushing blade 11 is fixedly installed on the inside of the crushing and grinding seat 9. The grinding head 12 is fixedly installed at the bottom of the rotating seat 8.
[0035] Through the above structure, the raw materials for autoclaved aerated concrete (AAC) blocks are evenly fed into the material processing cylinder 2 through multiple distribution pipes 3. The power motor 5 is started, driving the rotating shaft 6 to rotate. The rotating shaft 6 drives the crushing blades 7 to rotate, which perform preliminary crushing of the evenly falling AAC block raw materials. Simultaneously, the rotating shaft 6 drives the rotating seat 8 to rotate, which in turn drives the grinding head 12 to rotate. The rotating seat 8 then drives the first crushing blade 10 to rotate, while the second crushing blade 11 remains stationary. The initially crushed AAC blocks... The raw material enters the crushing blades 10 and 11, further pulverizing the autoclaved aerated concrete (AAC) block raw material. The further pulverized AAC block raw material then enters between the grinding head 12 and the grinding and crushing seat 9. The grinding head 12 and the grinding and crushing seat 9 work together to grind and crush the further pulverized AAC block raw material. This method can efficiently pulverize the AAC block raw material, ensuring the pulverization effect and the feeding quality of the AAC block raw material.
[0036] Specifically, the material crushing mechanism also includes an autoclaved aerated concrete block raw material adding pipe 4, which is fixedly connected to the material distribution pipe 3.
[0037] Through the above structure, the raw materials for autoclaved aerated concrete (AAC) blocks are added to the AAC block raw material adding pipe 4, and the AAC block raw materials are evenly added to the material processing cylinder 2 through multiple distributing pipes 3.
[0038] Specifically, the crushing blade 7 is located below the distribution pipe 3. There are multiple distribution pipes 3, and they are arranged in a ring with equal spacing. It should be noted that this facilitates the uniform addition of autoclaved aerated concrete block raw materials.
[0039] Specifically, a drive motor 13 is fixedly installed on the feeder body 1, and a conveying auger located inside the feeder body 1 is fixedly installed at the output end of the drive motor 13. A support base 14 is fixedly installed at the bottom of the feeder body 1, and a feeding pipe is fixedly installed at the bottom of the feeder body 1. It should be noted that when the drive motor 13 is started, the conveying auger can convey the crushed autoclaved aerated concrete block raw materials and discharge them through the feeding pipe.
[0040] Specifically, the first set of crushing blades 10 is set in two groups, and the second set of crushing blades 11 is set in one group. The second set of crushing blades 11 is located between the two sets of crushing blades 10. It should be noted that the raw materials of autoclaved aerated concrete blocks are further crushed.
[0041] Working principle:
[0042] S1: When processing the raw materials of autoclaved aerated concrete blocks, the operator adds the raw materials from the autoclaved aerated concrete block raw material adding pipe 4. The raw materials enter the material processing cylinder 2 through the distribution pipe 3. Since there are multiple distribution pipes 3 and they are arranged in a ring with equal spacing, the raw materials can be evenly dispersed into the material processing cylinder 2, avoiding the accumulation of raw materials and affecting the subsequent crushing effect.
[0043] S2: Start the power motor 5. The output end of the power motor 5 drives the rotating shaft 6 to rotate. When the rotating shaft 6 rotates, the crushing blade 7 fixed on its outer side rotates accordingly. Since the crushing blade 7 is located below the distribution pipe 3, the raw material falling from the distribution pipe 3 will directly contact the rotating crushing blade 7. The crushing blade 7 performs preliminary crushing on the raw material, breaking up larger clumps, and preparing for further crushing.
[0044] S3: The raw material after initial crushing continues to fall and enters the area where the rotating seat 8 and the crushing and grinding seat 9 are located. The rotating seat 8 at the bottom of the rotating shaft 6 rotates synchronously with the rotating shaft 6. The crushing blade 10 on the outside of the rotating seat 8 also rotates. The crushing and grinding seat 9 is fixed inside the material processing cylinder 2, and the crushing blade 21 on its inner side remains stationary. When the raw material passes between the crushing blade 10 and the crushing blade 21, the rotating crushing blade 10 and the stationary crushing blade 21 cooperate with each other to shear and impact the raw material, thereby achieving secondary crushing and further breaking down the small lumps and agglomerates remaining after initial crushing.
[0045] S4: The raw material after secondary crushing falls between the bottom of the rotating seat 8 and the crushing and grinding seat 9. The grinding head 12 at the bottom of the rotating seat 8 rotates with the rotating seat 8. The grinding head 12 and the inner wall of the crushing and grinding seat 9 squeeze and rub against each other to grind the raw material, grinding the secondary crushed raw material into finer and more uniform particles, ensuring that the raw material is thoroughly crushed. The crushed raw material enters the feeder body 1. The drive motor 13 is started, and the drive motor 13 drives the conveying auger to rotate. The conveying auger pushes the raw material to move in the feeder body 1 through the rotation of the spiral blades. Finally, the raw material is conveyed to the subsequent processing equipment through the feed pipe at the bottom of the feeder body 1.
[0046] The above provides a detailed description of a feeder for autoclaved aerated concrete (AAC) blocks provided by this utility model. Specific embodiments have been used to illustrate the principles and implementation methods of this utility model. The descriptions of these embodiments are merely for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
