Description

Technical Field

[0001] This invention relates to the field of concrete processing, and more specifically to a crack-resistant concrete and its processing method. Background Technology

[0002] Concrete, often simply called PT, is a general term for engineering composite materials made by binding aggregates together with cementing materials. The term "concrete" usually refers to cement concrete, also known as ordinary concrete, which is made by mixing cement as the cementing material, sand and gravel as aggregates, and water in a certain proportion. It is widely used in civil engineering. Crack resistance of concrete refers to its ability to resist cracking. The crack resistance of concrete is a comprehensive property, related to tensile strength, ultimate tensile deformation capacity, tensile modulus of elasticity, autogenous volume deformation, creep, and thermal properties. Crack-resistant concrete is generally made by adding crack-resistant fibers, such as polypropylene fibers and glass fibers, to concrete. During the production of crack-resistant concrete, the addition of crack-resistant fibers makes the mixing process difficult and prone to clumping. Summary of the Invention

[0003] This invention provides a crack-resistant concrete and its processing method, with the aim of reducing raw material waste during the manufacturing process.

[0004] The above objectives are achieved through the following technical solutions:

[0006] Step 1: Add cement, gravel, sand, and fiberglass to the processing device;

[0007] Step 2: Drive the processing device to mix the materials, and simultaneously inject water into the interior to form crack-resistant concrete;

[0008] Step 3: Drive the processing device to screen materials a second time, further enhancing the mixing effect of crack-resistant concrete;

[0009] Step 4: Remove the crack-resistant concrete from the processing equipment and load it onto a truck for transportation.

[0010] The concrete contains 10% cement, 65% aggregate, 24.5% sand, 0.5% glass fiber, and an appropriate amount of water.

[0011] The processing device includes a support frame, a mixing chamber fixedly connected to the support frame, a rotating ring rotatably connected to the mixing chamber, a filter plate fixedly connected to the lower end of the mixing chamber, a scraper fixedly connected to the rotating ring, the scraper contacting the inner wall of the mixing chamber, and a pressure roller rotatably connected to the rotating ring, the pressure roller contacting the filter plate.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0028] The invention will now be further described with reference to the accompanying drawings.

[0029] like Figure 1 A method for processing crack-resistant concrete includes the following steps:

[0030] Step 1: Add cement, gravel, sand, and fiberglass to the processing device;

[0031] Step 2: Drive the processing device to mix the materials, and simultaneously inject water into the interior to form crack-resistant concrete;

[0032] Step 3: Drive the processing device to screen materials a second time, further enhancing the mixing effect of crack-resistant concrete;

[0033] Step 4: Remove the crack-resistant concrete from the processing equipment and load it onto a truck for transportation.

[0034] A type of crack-resistant concrete contains 10% cement, 65% aggregate, 24.5% sand, 0.5% glass fiber, and an appropriate amount of water.

[0035] Cement is used to provide the binding material for concrete; gravel is used as coarse aggregate and sand as fine aggregate to provide the strength and stability of concrete; glass fiber is used to control shrinkage cracks in concrete and increase tensile strength.

[0036] like Figure 9 and Figure 10 To address the issue of reducing waste during the manufacturing process;

[0037] The processing device includes a support 104, a mixing chamber 103 fixedly connected to the support 104, a rotating ring 15 rotatably connected to the mixing chamber 103, a filter plate 402 fixedly connected to the lower end of the mixing chamber 103, a scraper 501 fixedly connected to the rotating ring 15, the scraper 501 contacting the inner wall of the mixing chamber 103, and a pressure roller 503 rotatably connected to the rotating ring 15, the pressure roller 503 contacting the filter plate 402.

[0038] During the mixing process, the processed raw materials are placed into the mixing chamber 103 for mixing. After mixing, the concrete is collected and transported by falling through the filter plate 402, thus ensuring that no lumps are generated during concrete mixing, which would affect the effect. Then, the rotating ring 15 is driven to rotate, which in turn drives the scraper 401 to rotate. The scraper 401 can scrape off the concrete residue on the inner wall of the mixing chamber 103, thus ensuring the integrity of the concrete raw materials. Since glass fiber is added to the crack-resistant concrete to increase its strength, the strip-shaped glass fiber will increase the possibility of lumps during mixing. Therefore, during the rotation of the rotating ring 15, the pressure roller 503 can be moved, and the pressure roller 503 rotates relative to the filter plate 402, which can crush the lumps of concrete that cannot pass through the filter plate 402, thus further increasing the integrity of the concrete raw materials.

[0039] like Figure 1 and Figure 11 To achieve the purpose of driving the rotating ring to rotate and thus mixing concrete;

[0040] A first rotary motor is fixedly connected to the bracket 104. The output shaft of the first rotary motor is frictionally connected to the rotating ring 15. Multiple inclined stirring plates 502 are fixedly connected to the rotating ring 15.

[0041] The bracket 104 is used to fix the processing device, thereby driving the first rotary motor on it to rotate, which in turn drives the rotating ring 15 to rotate through friction, thereby driving the stirring plate 502 to rotate, and thus stirring the raw materials in the mixing chamber 103.

[0042] like Figure 2 and Figure 3 To facilitate the processing of stored raw materials;

[0043] A hopper 11 is fixedly connected to the support 104. The hopper 11 is equipped with a partition plate, which divides the hopper 11 into four parts.

[0044] The lower end of the hopper 11 is rotatably connected to a turntable 101, which has a feed inlet 102. Four feed channels 12 are fixedly connected to the support 104, and the shape of the feed channels 12 is the same as that of the feed inlet 102.

[0045] Sand, gravel, cement, and glass fiber are added to the silo 11 in proportion. Then, the turntable 101 is driven to rotate, which in turn drives the feed inlet 102 to rotate, causing the raw materials to fall through the feed channel 12 and gradually add them to the mixing silo 103. By adding the raw materials layer by layer, the raw materials are initially mixed, thereby increasing the subsequent mixing speed and the preparation speed of crack-resistant concrete.

[0046] like Figure 4 and Figure 5To further limit the size of the stones;

[0047] Two separating cones 201 are rotatably connected in one of the feed channels 12. Each separating cone 201 is fixed with a driving blade 202. Each separating cone 201 is provided with a pressing roller 203 below it. Each pressing roller 203 is provided with pressing teeth 204. Each pressing roller 203 is rotatably connected to the feed channel 12.

[0048] The feed channel 12 containing the separating cone 201 is located at the location of the stones in the hopper 11. The stones fall onto the separating cone 201, which drives the two separating cones 201 to rotate, thereby driving the drive blades 202 to rotate. This allows the stones to be gradually fed from one side of the separating cone 201 to the other side. The distance between the two separating cones 201 at the point where the stones fall is relatively close, allowing smaller stones to fall. As the separating cones 201 rotate, the stones fall from small to large onto the compression rollers 203 below. The two compression rollers 203 rotate inward simultaneously, driving the compression teeth 204 to rotate. The compression teeth 204 gradually become denser from front to back. Since the required stones do not need to be too smooth, this ensures that small stones are not over-compressed, while large stones are sufficiently compressed, thus ensuring the size of the stones while accelerating the crushing efficiency.

[0049] like Figure 6 To prevent the glass fibers from tangling together;

[0050] Two rotating shafts 205 are rotatably connected in another feed channel 12, and multiple peeling teeth 206 are fixed on each rotating shaft 205.

[0051] The feed channel 12 where the rotating shaft 205 is located is below the glass fiber in the hopper 11. The glass fiber falls into the feed channel 12 through the feed port 102. At the same time, the two rotating shafts 205 are driven to rotate from the inside to the outside, which in turn drives the peeling teeth 206 to rotate. The multiple peeling teeth 206 can break up the glass fiber and make it fall, thereby preventing the strip glass fiber from tangling together and further increasing the subsequent mixing efficiency.

[0052] like Figure 7 This is to achieve the purpose of controlling the rotation of the shaft and the separation cone;

[0053] A drive shaft 13 is fixedly connected to the lower end of the turntable 101, and a second rotary motor is fixedly connected to the bracket 104. The output shaft of the second rotary motor is fixedly connected to the drive shaft 13. A face gear 301 is provided on the drive shaft 13. Two gears 302 are meshed on the face gear 301. The two gears 302 drive the rotating shaft 205 and the extrusion roller 203 respectively through two gear sets.

[0054] The second rotary motor drives the drive shaft 13 to rotate, which in turn drives the turntable 101 to rotate. At the same time, the face gear 301 follows the drive shaft 13 to rotate, which in turn meshes with and drives two gears 302 to rotate. One of the gears 302 then meshes with the gear set to drive two rotating shafts 205 to rotate, causing the two rotating shafts 205 to rotate relative to each other from the inside out. Simultaneously, the other gear set drives two separating cones 201 to rotate relative to each other inward. While the separating cones 201 are rotating, the other gear set drives two extrusion rollers 203 to rotate inward simultaneously.

[0055] like Figure 8 This is to achieve the goal of evenly distributing the materials within the mixing chamber;

[0056] An elastic plate 303 is fixedly connected to the drive shaft 13, a screen 304 is fixedly connected to the elastic plate 303, a push rod is fixedly connected to the screen 304, a corrugated plate 14 is connected to the lower end of the push rod, the corrugated plate 14 is rotatably connected to the drive shaft 13, a sleeve 401 is fixedly connected to the lower end of the corrugated plate 14, and the sleeve 401 is fixedly connected to the filter plate 402.

[0057] The screen 304 is positioned corresponding to the feed inlet 102. After the material falls from above, it enters the screen 304 through the feed channel 12. When the drive shaft 13 rotates, it drives the elastic plate 303 to rotate, which in turn drives the screen 304 to rotate. As the screen 304 rotates, the bottom push rod moves accordingly. The push rod is driven up and down by the corrugated plate 14, which causes the screen 304 to shake. This causes the material above to gradually shake and fall into the mixing chamber 103, thus distributing it evenly within the mixing chamber 103 and increasing the mixing rate.
