Description

Technical Field

[0001] This invention relates to the field of concrete technology, specifically to a high-insulation concrete and its preparation equipment. Background Technology

[0002] With increasing societal demands for energy-efficient buildings, traditional building materials are no longer sufficient to meet the needs of low-energy buildings. A significant portion of building heating and air conditioning energy consumption is due to heat loss through walls. Reducing this energy consumption would greatly improve energy efficiency. High-insulation concrete, as a new type of insulation material, boasts advantages such as excellent insulation performance, high durability, and environmental friendliness, effectively overcoming the shortcomings of traditional insulation materials. Furthermore, under increasingly stringent environmental regulations, the disposal of large quantities of solid waste has become a challenge. Using solid waste such as steel slag, blast furnace slag, and fly ash as raw materials for high-insulation concrete, and processing them through manufacturing equipment, not only reduces production costs but also achieves resource recycling, aligning with the concept of green and sustainable development.

[0003] However, existing high-insulation concrete preparation and crushing equipment still has the following problems during use: When crushing raw materials for high-insulation concrete, after the material is poured into the crusher, it is crushed by the internal crushing components. Some substandard material is sent back to the feeding position for secondary crushing to improve crushing efficiency. Then, during this process, the operation of the secondary recovery mechanism is fixed; it simply recovers and re-crushes the material. However, the amount of material recovered each time varies. When a large amount of material is recovered, the feed rate remains constant, which is equivalent to a surge in the feed rate per unit time, increasing the load on the machinery. Therefore, it is necessary to adjust the feed opening size according to the amount of material recovered to ensure that the crusher always operates at a suitable feed rate. When the amount of recovered material is large, the feed opening is reduced to ensure that the total amount of input and recovered material is consistent with the initial feed rate. Under normal conditions, the amount of material fed into the crusher is relatively constant. When the material enters the crusher for crushing, it can avoid damage caused by increased mechanical load due to rapid feeding. The feed inlet can automatically adjust to a suitable width to allow material to enter the crushing chamber, ensuring the continuity of the crushing process. At the same time, the amount of material recovered will also have a direct impact on the crushing rollers. Therefore, it is necessary to adjust the crushing mode of the crushing rollers according to the amount of material recovered, so that the crushing rollers can switch crushing modes automatically to crush the material to the required final particle size, thereby improving the overall crushing efficiency. By reasonably adjusting the size of the feed inlet and the crushing mode, the crusher can avoid operating under unnecessary high or low load conditions. When the feed inlet and crushing mode are appropriately adjusted according to the amount of material recovered, the crusher can operate in a more energy-efficient manner, reduce excessive wear on key components such as the crushing rollers, extend the service life of the equipment, and reduce equipment maintenance costs.

[0004] Therefore, we propose a high-insulation concrete and its preparation equipment to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a high-insulation concrete and its preparation equipment to solve the problem mentioned in the background art. In the current market, the existing high-insulation concrete and its preparation equipment crushers have a single operating mode during the secondary recycling of materials. This makes it inconvenient to reasonably adjust the feed inlet size and crushing mode according to the actual situation, resulting in the crusher operating under unnecessary high or low load conditions. When the feed inlet and crushing mode can be appropriately adjusted according to the amount of recycled materials, the crusher can operate in a more energy-efficient manner.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-insulation concrete, comprising the following raw materials: cement, fly ash, expanded perlite, polystyrene foam particles, cellulose ether, air-entraining agent, and water, wherein the specific proportions of the raw materials are: cement content 20%-35%, fly ash content 10%-20%, expanded perlite content 10%-30%, polystyrene foam particle content 5%-20%, cellulose ether content 0.05%-0.3%, air-entraining agent content 0.01%-0.05%, and water content 10%-15%.

[0007] Preferably, the cement, fly ash, expanded perlite, and polystyrene foam particles need to be pretreated before processing;

[0008] The specific preparation process of high-insulation concrete is as follows:

[0009] Raw material pretreatment: The required raw materials are crushed by a crusher to process them into appropriate particle sizes to ensure that all raw materials meet quality standards;

[0010] Dry mixing: Cement, fly ash, expanded perlite and polystyrene foam particles are put into a mixer for dry mixing. The mixing time is generally 3-5 minutes to ensure that the various dry materials are fully and evenly mixed.

[0011] Add water and additives and stir: After the dry mixture is stirred evenly, add a portion of water, and at the same time dissolve the cellulose ether and air-entraining agent in the water and add them to the mixer. Stir for about 5-8 minutes to fully hydrate the cementitious materials such as cement and fly ash. The cellulose ether plays a thickening and water-retaining role, and the air-entraining agent introduces tiny air bubbles evenly.

The end of the second electric push rod is fixed with a second oil tank, and the end of the second oil tank is slidably connected with a flat push plate. At the same time, the second oil tank is connected to one of the inner cavities of the first oil tank.

The interior of the regulating box is connected to the oil cavity by a connecting pipe, and the oil cavity is opened in the middle of the inner side of the truss. A piston rod is slidably connected in the oil cavity, and the piston rod is fixedly connected to the top of the first electric push rod.

[0026] Compared with existing technologies, the beneficial effects of the high-insulation concrete and its preparation equipment of this invention are: during use, when the material is recycled and processed, the feed inlet size and crushing mode can be reasonably adjusted according to the actual situation, which can avoid the crusher operating under unnecessary high or low load conditions. After the feed inlet and crushing mode are adaptively adjusted according to the amount of recycled material, the crusher can operate in a more energy-efficient manner. The specific details are as follows:

[0027] 1. Through the designed load-bearing components, during the secondary recycling of materials, the variables of the corresponding operating parts are adjusted according to the actual recycling volume. When material accumulates in the return pipe, the return pipe will move downward due to gravity, thereby applying pressure to the bracket. Initially, the electromagnetic plate on the piston plate is energized, thus fixing the piston plate in a fixed position. The force of the bracket compresses the piston plate to slide downward in the first oil tank. When the material is discharged, the electromagnetic plate on the first oil tank at the sliding position of the piston plate is energized, thereby locking the downward displacement position of the piston plate. The oil inside the tank will be squeezed out, and then the first electric push rod will work to tilt the truss and pour out the material inside the return pipe. After the material starts to pour, the electromagnetic plate on the piston plate will be de-energized, and the piston plate will be in an active state. After the pouring is finished, the first electric push rod will drive the truss to reset. At this time, the electromagnetic plate on the first oil tank will be de-energized, and the piston plate will be in a free reset state, which will facilitate subsequent use. Each change in the weight accumulated in the return pipe will be directly reflected by the oil output of the first oil tank. The change in the amount of oil output affects the subsequent feed rate and crushing mode adjustment.

[0028] 2. By setting up an inlet adjustment component, when the material is being recycled for the second time, the feed rate of the hopper can be adjusted according to the amount of material recycled. After the oil in the first oil tank is delivered to the second oil tank, the flat push plate in the second oil tank is pushed out, thereby changing the initial position of the flat push plate. With the pushing amount of the second electric push rod remaining unchanged, the change in the position of the flat push plate causes the distance of the push baffle to change accordingly. Thus, when the recycled material is dumped and crushed, the size of the feed hopper's discharge port is adjusted adaptively, thereby reducing the feed rate of the hopper to match the amount of recycled material, achieving a more even feeding amount, reducing the load on 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.

[0029] 3. By adjusting the crushing mode through the set crushing mode adjustment component, the crushing mode is adjusted during the secondary recycling of materials, so that the crusher is in a good crushing mode to perform secondary processing of materials. After the oil in the first oil tank is injected into the third oil tank, the moving plate extends, and the abutment block on the moving plate also extends. Then, when the shaft drives the crushing roller to rotate, the protrusion on the crushing roller will intermittently abut against the abutment block, so that the crushing roller moves back and forth relative to each other while rotating, thereby improving the crushing efficiency and accelerating the quality of secondary crushing of materials.

[0030] 4. By setting the angle adjustment component, the uniformity of material feeding is maintained during secondary material recycling, allowing the crusher to crush more stably. 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 extend accordingly under the push of the spring, keeping it in contact with the adjustment box. This allows for adjustment of the upward movement speed of the top plate when dumping materials of different recycling amounts. When the first electric push rod drives the truss to rotate downward to dump materials, it will drive the piston rod to slide synchronously in the oil cavity. The oil in the oil cavity will be transported between the adjustment box and the slide, thereby pushing the slide upward. After the slide moves upward, it will push the left end of the bracket to deflect upward, thereby adjusting the tilt angle of the material feeding pipe according to the weight of the material, thus adjusting the material feeding speed, maintaining uniform feeding, which is conducive to the smooth operation of the crushing components and extending their service life.

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] Please see Figures 1-17 As shown, the present invention provides a technical solution: a high-insulation concrete, comprising the following raw materials: cement, fly ash, expanded perlite, polystyrene foam particles, cellulose ether, air-entraining agent, and water. The specific proportions of the raw materials are as follows: cement content 20%-35%, fly ash content 10%-20%, expanded perlite content 10%-30%, polystyrene foam particle content 5%-20%, cellulose ether content 0.05%-0.3%, air-entraining agent content 0.01%-0.05%, and water content 10%-15%.

[0051] Cement, fly ash, expanded perlite, and polystyrene foam particles require pretreatment before processing;

[0052] The specific preparation process of high-insulation concrete is as follows:

[0053] Raw material pretreatment: The required raw materials are crushed by a crusher to process them into appropriate particle sizes to ensure that all raw materials meet quality standards;

[0054] Dry mixing: Cement, fly ash, expanded perlite and polystyrene foam particles are put into a mixer for dry mixing. The mixing time is generally 3-5 minutes to ensure that the various dry materials are fully and evenly mixed.

[0055] Add water and additives and stir: After the dry mixture is stirred evenly, add a portion of water, and at the same time dissolve the cellulose ether and air-entraining agent in the water and add them to the mixer. Stir for about 5-8 minutes to fully hydrate the cementitious materials such as cement and fly ash. The cellulose ether plays a thickening and water-retaining role, and the air-entraining agent introduces tiny air bubbles evenly.

[0056] Molding and curing: The mixed high-insulation concrete can be poured into molds for molding.

[0057] A high-insulation concrete preparation device includes a crusher housing 1, the bottom of which is fixedly installed on the top of a base 2. The top of the base 2 is connected to the discharge port of the crusher housing 1. A feed hopper 3 is provided on the top of the crusher housing 1. A motor 4 is installed on the rear side of the crusher housing 1, and the output end of the motor 4 is coaxially connected to one of the gear sets 5. The gear set 5 is bearing-connected to the rear side of the crusher housing 1. A shaft 6 is integrally installed in the middle of the gear set 5, and a crushing roller 7 is slidably connected to the outer side of the shaft 6. A screen 8 is provided on the lower inner side of the machine housing 1, and a return hopper 9 is connected to the outer right side of the crusher housing 1. A pusher 10 is provided in the return hopper 9. Material channels 11 for material inlet and outlet are opened on the upper and lower parts of the right side of the crusher housing 1. It also includes a shaft 6, which is a rectangular structure. The shaft 6 is arranged in a one-to-one correspondence with the crushing roller 7. The crushing roller 7 is located in the middle of the inner side of the crusher housing 1. The outlet of the top material channel 11 is connected to the return pipe 12. The return pipe 12 is connected to the inner wall of the top right side of the crusher housing 1 through a corrugated pipe.

[0058] First, the basic components and operation of the device are introduced. The raw material of high-insulation concrete to be processed is poured into the feed hopper 3 at 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, thereby crushing the raw material. The qualified material will fall through the screen 8 and be collected. The material with unqualified particle size will enter the return hopper 9 through the material channel 11 at the bottom, and then be conveyed by the pusher 10 to the material channel 11 at the top and enter the return pipe 12. The return pipe 12 accumulates the recovered material and then discharges it at regular intervals for secondary processing. This cycle is used for crushing.

[0059] Example 1: To address the issue that some high-insulation concrete crushers are inconvenient to adjust the variables of relevant operating components according to actual conditions during secondary material recycling, which can easily damage the machinery, the following solution is proposed. Please refer to the following for details. Figures 2-5 , Figure 7 , Figure 9 , Figure 12 and Figure 17 As shown;

[0060] The bearing assembly 13 is located below the return pipe 12 and between the inner wall of the right side of the crusher housing 1. The bearing assembly 13 is variablely adjusted according to the weight of the recovered material. The bearing assembly 13 includes a first electric push rod 132 hinged to the inner wall of the right side of the crusher housing 1. The first electric push rod 132 moves periodically. A truss 131 is slidably hinged to the top of the first electric push rod 132. The right side of the truss 131 is hinged to the inner wall of the right side of the crusher housing 1. A first oil tank 133 is installed in the middle of the top surface of the truss 131. A piston plate 134 is slidably connected through the top of the first oil tank 133. A bracket 137 is fixed to the top of the piston plate 134. The top of the bracket 137 supports the return pipe 12. The piston plate 134 is set to a spring-connected telescopic state. An electromagnetic plate 135 is provided in the telescopic space of the piston plate 134. The piston plate 134 is positioned by the electromagnetic plate 135 and reset by the spring.

[0061] In use, when material accumulates in the return pipe 12, the return pipe 12 will move downward due to gravity, thereby putting pressure on the bracket 137. In the initial state, the electromagnetic plate 135 on the piston plate 134 is energized, thereby fixing the piston plate 134 in a fixed state. The force of the bracket 137 squeezes the piston plate 134 to slide downward in the first oil tank 133. When the material is discharged, the electromagnetic plate 135 on the first oil tank 133 at the sliding position of the piston plate 134 is energized, thereby locking the downward displacement position of the piston plate 134. The oil inside the first oil tank 133 will be squeezed out, and then the first electric push rod 132 works, driving the truss 131 to tilt and pour out the material inside the return pipe 12.

[0062] refer to Figure 9 , Figure 12 and Figure 17 As shown, the first oil tank 133 is provided with four inner cavities, and the bottom of the piston plate 134 is divided into four parts. Each inner cavity corresponds to the bottom branch of the piston plate 134. An electromagnetic plate 135 is installed on the inner wall of the piston plate 134 at the sliding part of the first oil tank 133. The branches of the piston plate 134 are made of magnetic material. At the same time, an elastic telescopic rod 136 is connected between the top of the first oil tank 133 and the top and bottom surfaces of the piston plate 134.

[0063] After the material begins to be poured, the electromagnetic plate 135 on the piston plate 134 is de-energized, and the piston plate 134 is in an active state. After the pouring is completed, the first electric push rod 132 will drive the truss 131 to reset. At this time, the electromagnetic plate 135 on the first oil tank 133 is de-energized, and the piston plate 134 will be in a free reset state, which facilitates subsequent use. Each change in the weight accumulated in the return pipe 12 will be directly reflected by the oil output of the first oil tank 133. The change in the amount of oil output affects the subsequent adjustment of the feed rate and crushing mode.

[0064] Example 2: To address the issue that some high-insulation concrete crushers, during secondary material recycling, have difficulty adjusting the feed rate according to the actual size of the secondary recycling volume, the following solution is proposed. Please refer to the following for details. Figures 4-5 , Figures 7-8 , Figure 13 and Figure 15 As shown;

[0065] The feed inlet adjustment component 14 is located in the inner wall of the top inlet of the crusher housing 1. The feed inlet adjustment component 14 adjusts the feed amount of the feed hopper 3 according to the amount of recycled material. The feed inlet adjustment component 14 includes a transverse groove 141 symmetrically opened on the inner wall of the top inlet of the crusher housing 1. A second electric push rod 142 is fixed in the transverse groove 141. A second oil tank 143 is fixed at the end of the second electric push rod 142. A flat push plate 144 is slidably connected to the end of the second oil tank 143. The second oil tank 143 is connected to one of the inner cavities of the first oil tank 133. A baffle 145 is provided on the opposite side of the flat push plate 144. The baffle 145 is slidably connected to the transverse groove 141 by a spring.

[0066] In use, after the oil in the first oil tank 133 is transported to the second oil tank 143, the flat push plate 144 in the second oil tank 143 is pushed out, thereby changing the initial position of the flat push plate 144. With the pushing amount of the second electric push rod 142 remaining unchanged, the change in the position of the flat push plate 144 causes the distance of movement of the push baffle 145 to change accordingly. Thus, when dumping and crushing the secondary recycled material, the size of the discharge port of the feed hopper 3 is adjusted adaptively, thereby reducing the feeding amount of the feed hopper 3 to match the amount of secondary recycled material, achieving a more even feeding amount, reducing the load on the crushing components. 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.

[0067] Example 3: To address the problem that some high-insulation concrete crushers suffer damage due to the inconvenience of adjusting the crushing mode during secondary material recycling, resulting in unnecessary high or low load operation, the following solution is proposed. Please refer to the following for details. Figures 4-8 , Figure 14 and Figure 16 As shown;

[0068] The crushing mode adjustment component 15 is disposed on the front side of the crushing roller 7 and on the inner wall of the front side of the crusher housing 1. The crushing mode adjustment component 15 adjusts the crushing mode of the crushing roller 7 according to the amount of material to be recovered. The crushing mode adjustment component 15 includes a groove 151 opened on the inner wall of the front side of the crusher housing 1. A third oil tank 152 is fixed in the groove 151. The third oil tank 152 is connected to one of the inner cavities of the first oil tank 133. A moving plate 153 is slidably connected to the outer side of the third oil tank 152. A contact block 154 is mirror-symmetrically arranged on the moving plate 153. The contact block 154 and the protrusion 155 are intermittently misaligned and contact each other. The protrusion 155 is installed at an equal angle on the front end of the crushing roller 7. A spring is installed between the rear end face of the crushing roller 7 and the inner wall of the crusher housing 1. The crushing roller 7 forms a longitudinal movable structure through the contact block 154, the protrusion 155 and the spring.

[0069] In use, when the oil in the first oil tank 133 is injected into the third oil tank 152, the moving plate 153 extends out, and the abutting block 154 on the moving plate 153 also extends out. Then, when the shaft 6 drives the crushing roller 7 to rotate, the protrusion 155 on the crushing roller 7 will intermittently abut against the abutting block 154, thereby causing the crushing roller 7 to move back and forth relative to each other while rotating, thereby improving the crushing efficiency and accelerating the quality of secondary crushing of materials.

[0070] Example 4: To maintain uniform material feeding during secondary material recycling and ensure more stable crushing operations, the following solution is proposed. Please refer to the following for details. Figures 9-12 As shown;

[0071] Angle adjustment component 16 is located below return pipe 12, and angle adjustment component 16 balances the falling speed when recycled material is discharged for a second time. Angle adjustment component 16 includes adjustment box 161 slidably connected to the top of truss 131, and adjustment box 161 is configured as two parts with adjustable internal volume. Hollow sliding cavity 162 is provided in the middle of both sides of adjustment box 161, and sealing plate 163 connecting the two sides of adjustment box 161 is slidably connected in the sliding cavity 162. At the same time, the sealing plate 163 is configured as a "U" shaped structure in side view. The interior of sliding cavity 162 is connected to one of the inner cavities of the first oil tank 133. A slide frame 164 is slidably connected through the top of adjustment box 161, and a lateral extension plate 165 is connected to the bottom of slide frame 164 by spring. The extension plate 165 is in close contact with the inner wall of adjustment box 161.

[0072] When in use, after the oil in the first oil tank 133 is injected into the sliding cavity 162, it will push the adjustment boxes 161 on both sides to slide on both sides of the sealing plate 163, thereby expanding the internal space of the adjustment box 161. At the same time, the extension plate 165 at the bottom of the slide 164 will also extend accordingly under the push of the spring, keeping it in contact with the adjustment box 161, so as to adjust the upward movement speed of the top plate 166 when different amounts of recycled materials are poured.

[0073] refer to Figures 9-12 As shown; and the top of the carriage 164 is connected to the top plate 166, and the top plate 166 extends out and abuts against the bottom of the bracket 137. The interior of the regulating box 161 is connected to the oil chamber 168 through the connecting pipe, and the oil chamber 168 is opened in the middle of the inner side of the truss 131. The piston rod 167 is slidably connected in the oil chamber 168, and the piston rod 167 is fixedly connected to the top of the first electric push rod 132.

[0074] In use, when the first electric push rod 132 drives the truss 131 to rotate downwards and dump materials, it will drive the piston rod 167 to slide synchronously in the oil chamber 168. The oil in the oil chamber 168 will be transported between the regulating box 161 and the slide 164, thereby pushing the slide 164 to move upwards. After the slide 164 moves upwards, it will push the left end of the bracket 137 to deflect upwards, thereby adjusting the tilt angle of the return pipe 12 according to the weight of the material, thereby adjusting the material feeding speed, maintaining uniform feeding, which is conducive to the smooth operation of the crushing components and extending their service life.
