Description

Technical Field

[0001] The invention relates to the technical field of concrete, in particular to high thermal insulation concrete and preparation equipment thereof. Background Art

[0002] As society's requirements for building energy conservation continue to increase, traditional building materials can no longer meet the needs of low-energy buildings. In the energy consumption of building heating and air-conditioning, wall heat loss accounts for a relatively high proportion. If this part of the energy consumption can be reduced, the energy utilization efficiency will be greatly improved. High-insulation concrete, as a new type of insulation material, has the advantages of good insulation performance, strong durability, and green environmental protection. It can effectively overcome the shortcomings of traditional insulation building materials. At the same time, in the context of increasingly stringent environmental protection, the treatment of large amounts of solid waste has become a problem. Using solid waste such as steel slag, slag, and fly ash as raw materials for high-insulation concrete and crushing and processing them through preparation equipment can not only reduce production costs, but also achieve resource recycling, which is in line with the concept of green and sustainable development.

[0003] However, the existing high-insulation concrete preparation and crushing equipment still has the following problems during use: when crushing the high-insulation concrete raw materials, after the materials are poured into the crusher, they are crushed by the internal crushing components, and some materials that do not meet the standards will be sent back to the feeding position for secondary crushing, so as to improve the crushing efficiency; then, during this process, the operation of the secondary recovery mechanism is fixed, and the materials are simply recycled and crushed again, but the amount of material recovered each time varies. When the recycled material is large, the feed amount remains unchanged, which is equivalent to a surge in the feed amount per unit time, which will increase the load on the machine, and then it is necessary to adjust the feed port size according to the amount of secondary recycled material to ensure that the crusher always works at an appropriate feed rate. When the amount of recycled material is large, the feed port is reduced to make the total amount of input and recycled materials consistent with the normal The amount of material put in under normal conditions is equivalent. When entering the crusher for crushing, it can avoid damage caused by increased mechanical load due to fast feeding. The feed port can be automatically adjusted to an appropriate width to allow the material to enter the crushing chamber to ensure the continuity of the crushing process. At the same time, the amount of recycling will also have a direct impact on the crushing roller, so it is necessary to adjust the crushing mode of the crushing roller according to the amount of recycled material, so that the crushing roller is in a state where it can switch the crushing mode by itself and crush the material to the required final particle size, thereby improving the overall crushing efficiency. By reasonably adjusting the size of the feed port and the crushing mode, the crusher can be prevented from running under unnecessary high or low load conditions. When the feed port and the crushing mode are properly adjusted according to the amount of recycled material, the crusher can work in a more energy-saving manner, reduce excessive wear of key components such as the crushing roller, extend the service life of the equipment, and reduce equipment maintenance costs.

[0004] Therefore, we propose a high thermal insulation concrete and a preparation device thereof to solve the above-mentioned problems. Summary of the invention

[0016] Compared with the prior art, the high thermal insulation concrete and the preparation equipment of the present invention have the following beneficial effects: when in use, during the use process, when the material is recycled for the second time, the feed port size and the crushing mode can be reasonably adjusted according to the actual situation, so that the crusher can be prevented from running under unnecessary high load or low load. After the feed port and the crushing mode are adaptively adjusted according to the amount of recycled material, the crusher can work in a more energy-saving manner. The specific contents are as follows: 1. By setting the bearing assembly, when the material is recycled for the second time, the variables of the corresponding operating components are adjusted according to the actual recycling amount. When the material in the return pipe accumulates, the return pipe will move downward due to gravity, thereby exerting pressure on the bracket. In the initial state, the electromagnetic sheet on the piston plate is in an energized state, thereby making the piston plate fixed up and down. The force of the bracket squeezes the piston plate to slide downward in the first oil tank. When it is time to export the material, the electromagnetic sheet on the first oil tank and the sliding position of the piston plate is in an energized state, thereby locking the position of the downward displacement of the piston plate, and the first The oil inside the oil tank will be squeezed out, and then the first electric push rod will work, driving the truss to tilt and pour out the material inside the return pipe. After the material starts to pour out, the electromagnetic piece on the piston plate is powered off, and the piston plate is in an active state. After the dumping is completed, the first electric push rod will drive the truss to reset. At this time, the electromagnetic piece on the first oil tank is powered off, and the piston plate will be in a free reset state, which is convenient for subsequent use. Each change in the accumulated weight in the return pipe will be directly reflected by the oil output of the first oil tank. The change in the size of the oil output affects the subsequent adjustment of the feed amount and crushing mode; 2. By setting the feed inlet adjustment component, when the material is recycled for the second time, the feed amount is not convenient to adjust the discharge amount of the feed hopper according to the size of the secondary recycling amount. After the oil in the first oil tank is transported to the second oil tank, the push plate in the second oil tank is pushed out, thereby changing the initial position of the push plate. When the pushing amount of the second electric push rod remains unchanged, the change in the position of the push plate causes the distance of the push baffle to change accordingly. Therefore, when the secondary recycled material is dumped and crushed, the size of the feed inlet of the feed hopper is adaptively adjusted, thereby reducing the feed amount of the feed hopper to match the amount of secondary recycled material, achieving a more balanced feeding amount, and reducing the load of the crushing component. After the baffle is pushed, the spring is in a stretched state. When the truss is reset, the baffle is reset under the action of the spring tension, which is convenient for subsequent use. 3. Through the crushing mode adjustment component, when the material is recycled for the second time, the crushing mode is adjusted so that the crusher can process the material for the second time in a good crushing mode. After the oil in the first oil tank is injected into the third oil tank, the moving plate extends, and the resistance block on the moving plate also extends. When the shaft drives the crushing roller to rotate, the protrusion on the crushing roller will intermittently displace and resist the resistance block, so that the crushing roller moves back and forth relative to each other while rotating relative to each other, thereby improving the crushing efficiency and accelerating the quality of the secondary crushing of the material. 4. By setting up the angle adjustment component, the uniformity of material discharge is maintained during the secondary material recycling process, so that the crusher can perform crushing in a more stable manner. After the oil in the first oil tank is injected into the sliding cavity, it will push the adjustment boxes on both sides to slide on both sides of the sealing plate, thereby expanding the internal space of the adjustment box. At the same time, the extension plate at the bottom of the slide will also be pushed by the spring to keep in contact with the adjustment box and extend accordingly, so as to adapt to the different recycled amounts of materials for dumping. When the first electric push rod drives the truss to rotate downward to dump the material, it will drive the piston rod to slide in the oil chamber synchronously, and the oil in the oil chamber will be transported between the adjustment box and the slide, thereby pushing the slide to move up. After the slide moves up, it will push the left end of the bracket to deflect upward, and then adjust the inclination angle of the recovery pipe discharge according to the weight of the material, thereby adjusting the material discharge speed and maintaining uniform discharge, which is beneficial to the benign operation of the crushing component and prolongs its service life.

[0022] A preparation device for high thermal insulation concrete, comprising a crusher shell 1, wherein the bottom of the crusher shell 1 is fixedly mounted on the top of a base 2, and the top of the base 2 is connected to the discharge port of the crusher shell 1, and a feed hopper 3 is arranged on the top of the crusher shell 1, a motor 4 is installed on the rear side of the crusher shell 1, and the output end of the motor 4 is coaxially connected to one of the gear sets 5, and the gear set 5 is connected to the rear side of the crusher shell 1 by a bearing, and a shaft 6 is integrally mounted on the middle part of the gear set 5, and a crushing roller 7 is slidably connected to the outer side of the shaft 6, and the crushing roller 7 is slidably connected to the outer side of the shaft 6. A screen 8 is arranged at the lower inner side of the housing 1, and a return bin 9 is connected to the right outer side of the crusher housing 1, and a pusher 10 is arranged in the return bin 9, and a material channel 11 for material in and out is opened at the upper and lower parts of the right side of the crusher housing 1: it also includes a shaft rod 6, which is arranged in a rectangular structure, and the shaft rod 6 and the crushing roller 7 are arranged one by one, and the crushing roller 7 is arranged in the middle of the inner side of the crusher housing 1, and the outlet of the top material channel 11 is connected to the return pipe 12, and the return pipe 12 is connected to the inner wall of the top right side of the crusher housing 1 through a corrugated pipe; First, the basic components and use of the device are introduced. The raw materials of high thermal insulation concrete to be processed are poured from the feed hopper 3 on the top of the crusher shell 1. After the motor 4 drives the gear set 5 to rotate, the gear set 5 drives the crushing roller 7 to start running, and then the raw materials are crushed. Qualified materials will be collected from the screen 8, and the materials with unqualified particle size will enter the return bin 9 through the material channel 11 at the bottom, and then be transported to the upper material channel 11 by the pusher 10 and enter the return pipe 12. The return pipe 12 accumulates and recovers the materials and then regularly outputs them for secondary processing, and the crushing process is carried out in this cycle; Embodiment 1: In order to solve the problem that some high-insulation concrete crushers are inconvenient to adjust the variables of the corresponding operating components according to the actual situation during the secondary recycling of materials during use, which may easily damage the machine, the following solution is proposed. Please refer to Figure 2-Figure 5 , Figure 7 , Fig. 9 , Fig.12 and Fig.17 As shown; The bearing assembly 13 is arranged between the lower part of the return pipe 12 and the right inner wall of the crusher shell 1, and the bearing assembly 13 is variable-adjusted according to the weight of the recycled material. The bearing assembly 13 includes a first electric push rod 131 hinged on the right inner wall of the crusher shell 1, and the first electric push rod 131 is regularly movable, and the top of the first electric push rod 131 is slidably hinged with a truss 132, and the right side of the truss 132 is hinged on the right inner wall of the crusher shell 1, and a first oil tank 133 is installed in the middle of the top surface of the truss 132, and a piston plate 134 is slidably connected through the top of the first oil tank 133, and a bracket 137 is fixed on the top of the piston plate 134, and the top of the bracket 137 carries the return pipe 12, the piston plate 134 is set to a telescopic state connected with a spring, and an electromagnetic sheet 135 is arranged in the telescopic space of the piston plate 134, and the piston plate 134 is positioned by the electromagnetic sheet 135 and reset by the spring; During use, when the material in the return pipe 12 accumulates, the return pipe 12 will move downward due to gravity, thereby applying pressure to the bracket 137. In the initial state, the electromagnetic sheet 135 on the piston plate 134 is in an energized state, thereby making the piston plate 134 fixed up and down, and the force of the bracket 137 squeezes the piston plate 134 to slide downward in the first oil tank 133. When it is time to export the material, the electromagnetic sheet 135 on the first oil tank 133 at the sliding position of the piston plate 134 is in an energized state, thereby locking the downward displacement position of the piston plate 134, and the oil inside the first oil tank 133 will be squeezed out, and then the first electric push rod 132 works to drive the truss 131 to tilt, and pour out the material inside the return pipe 12; refer to Fig. 9 , Fig.12 and Fig.17 As shown, the first oil tank 133 is provided with four inner chambers, and the bottom of the piston plate 134 is provided with four parts, each inner chamber corresponds to the bottom branch of the piston plate 134, and an electromagnetic sheet 135 is installed on the inner wall of the piston plate 134 at the sliding part of the first oil tank 133, and the branch of the piston plate 134 is provided with a magnetic material, and an elastic telescopic rod 136 is connected between the top of the first oil tank 133 and the bottom surface of the top of the piston plate 134; After the material starts to dump, the electromagnetic sheet 135 on the piston plate 134 is powered off, and the piston plate 134 is in an active state. After the dumping is completed, the first electric push rod 132 will drive the truss 131 to reset. At this time, the electromagnetic sheet 135 on the first oil tank 133 is powered off, and the piston plate 134 will be in a free reset state, which is convenient for subsequent use. Each change in the accumulated weight in the return pipe 12 will be directly reflected through the oil output of the first oil tank 133.

[0023] Embodiment 2: In order to solve the problem that the feed rate of some high-insulation concrete crushers is not easy to adjust according to the actual situation of the secondary recycling amount during the secondary recycling of materials during use, the following solution is proposed.

When the pushing amount of the second electric push rod 142 remains unchanged, the change in the position of the push plate 144 causes the moving distance of the push baffle 145 to change accordingly. Therefore, when the secondary recovered materials are dumped and crushed, the size of the drop opening of the feed hopper 3 is adaptively adjusted, thereby reducing the feed amount of the feed hopper 3 to match the amount of secondary recovered materials, achieving a more balanced feed amount, and reducing the load on the crushing assembly. After the baffle 145 is pushed, the spring is in a stretched state. When the truss 131 is reset, the baffle 145 is reset under the action of the spring tension, which is convenient for subsequent use.

[0024] Embodiment 3: In order to solve the problem that some high-insulation concrete crushers are inconvenient to adjust the crushing mode during the secondary recycling of materials during use, which causes the crusher to be damaged by running under unnecessary high or low load conditions, the following solution is proposed.
