Description

Technical Field

[0001] This invention relates to the field of composite mortar technology, specifically to lightweight thermal insulation composite mortar and its production equipment. Background Technology

[0002] Currently, both domestic and international building wall insulation generally uses board or component-based insulation materials, which are expensive, technically difficult to construct, and have poor impact resistance, but offer good insulation performance and are suitable for cold regions. Another insulation material exists: a polystyrene granule external wall insulation system. This system consists of an interface layer, an insulation layer, and a crack-resistant protective layer, providing insulation and protection. However, existing polystyrene granule external wall insulation systems contain cement in each layer. Since cement is a hydraulic material, it forms cement paste with hydrates, which typically takes 28 days to reach its design strength. Premature dehydration stops hydration, and the strength no longer increases. Cement-containing materials are plastic materials mixed with water, and their volume shrinks as water evaporates. During this shrinkage process, if the cement-containing material has no strength or very low strength, the shrinkage stress exceeds the material's tensile strength, resulting in concentrated large cracks.

[0003] Currently, in order to protect the environment and improve the quality of building mortar, my country has begun to mandate the use of premixed mortar. Premixed mortar is divided into two types: dry-mixed and wet-mixed. The current manufacturing and use method for commercial dry-mixed mortar is as follows: at the dry-mixed mortar manufacturing plant, cement, mineral admixtures, lime or gypsum, additives, and dried sand (moisture content less than 0.5%) are mixed to produce dry-mixed mortar for shipment. Water is then added at the construction site to prepare the mortar for use.

[0004] For example, Chinese Patent Publication No. CN102371625A discloses the following technical solution: a dry-wet composite mixing equipment for powder and granular materials, comprising a wet mixer and a dry mixer installed above the wet mixer. The dry material outlet of the dry mixer is located directly above the dry material inlet hopper of the wet mixer. It also includes a weighing sensor mounted on a support and a telescopic support. After cement mixture and sand are transported to the site, they are sequentially metered, dry-mixed, and wet-mixed to prepare wet-mixed mortar for construction. This invention integrates dry and wet mixing into one device, and dry mixing and metering are completed in the same container. Since the cement mixture and sand used for mixing dry-mixed mortar are no longer mixed and stored, this invention completely solves the segregation problem during the transportation of dry-mixed mortar, ensuring mortar quality. On the other hand, using the equipment of this invention, the sand does not need to be pre-dried, reducing the energy cost of drying sand while realizing the commercialization and professional production and use of dry-mixed pre-mixed mortar.

[0005] The existing technology has the following problems:

[0006] Dry-mixed mortar is typically transported using tanker trucks or specialized dry-mixed mortar transport vehicles. Because dry-mixed mortar is a bulk, powdery, or granular material, its inherent characteristics, such as significant differences in particle size and specific gravity among its components, lead to segregation during production and transportation. Using existing dry-mixed mortar premixing equipment, tanker trucks, or specialized dry-mixed mortar transport vehicles, the mixing, conveying, and loading processes during production, as well as the bumps and jolting during transport, result in significant segregation. This leads to uneven composition, fluctuating performance, and substantial impact on mortar quality during use. Summary of the Invention

[0007] This invention provides lightweight thermal insulation composite mortar and its production equipment to solve the problems mentioned in the background art.

[0008] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: lightweight thermal insulation composite mortar, comprising: 35-40 parts cement, 8-12 parts converter slag granules, 12-18 parts reinforcing material, 16-22 parts composite thermal insulation aggregate, 0.25-0.35 parts resin-type redispersible latex powder, 0.6-0.9 parts cold-water type polyvinyl alcohol, 0.1-0.2 parts hydroxypropyl methylcellulose ether, 0.01-0.03 parts air-entraining agent, 0.06-0.1 parts water glass, 0.005-0.01 parts inorganic retarder, 8-13 parts polystyrene granules, 30-50 parts vitrified microspheres, 1-2 parts redispersible latex powder, and 0.2-0.6 parts water-retaining agent.

[0009] By incorporating the above technical solution, the mortar volume can be prevented from shrinking as water evaporates by adding a water-retaining agent. During the shrinkage process, if the cement-containing material has no strength or very low strength, the shrinkage stress will be greater than the tensile strength of the material, and the shrinkage will manifest as a problem of relatively concentrated large cracks.

[0010] The technical solution adopted in this invention is: a lightweight thermal insulation composite mortar production equipment, including a mixing tank, a grinding box is provided above the top of the mixing tank, and the two sides of the grinding box are fixedly connected to the top of the mixing tank through support plates;

[0011] A discharge port for discharging mortar is fixedly installed at the bottom of the front of the mixing tank. Liquid injection pipes for injecting the mixture are fixedly installed on both sides of the top of the mixing tank. A feed port for adding materials is fixedly installed at the top of the grinding tank. A grinding component for grinding materials is provided on the inner wall of the grinding tank. A direct drive motor for driving the grinding component is fixedly installed on the back of the grinding tank.

[0012] The mixing tank and the grinding tank are connected by a connecting pipe.

[0013] By adopting the above technical solution, the solution provides liquid injection pipes on both sides of the top of the mixing tank, so that the mixture can be more evenly mixed on the inner wall of the mixing tank.

[0014] A further improvement of the technical solution of the present invention is that: the grinding assembly includes a rotating rod, the rotating rod is rotatably connected to the inner wall of the grinding box, and one end of the rotating rod is fixedly connected to the output end of the direct drive motor. Support frames are respectively provided on both sides of the rotating rod, and grinding rollers are rotatably connected to the inner walls of the two sets of support frames through rotating shafts, and the grinding rollers are rollingly connected to the inner wall of the grinding box.

[0015] The above technical solution involves adding materials through the feed inlet and starting a direct drive motor to rotate the rotating rod. This allows the rotating rod to drive the grinding roller to roll on the inner wall of the grinding box. Due to the circular motion trajectory, the grinding roller can repeatedly crush and grind the materials in the grinding box, making the material particles smaller. This improves the effect of subsequent mixing and mortar preparation, and avoids uneven mixing.

[0016] A further improvement to the technical solution of the present invention is that an electric telescopic plate is fixedly installed between the outer wall of the rotating rod and the two sets of support frames.

[0017] The above technical solution allows for adjustment of the distance between the grinding roller and the inner wall of the grinding box by setting the extension and retraction of the electric telescopic plate, so as to facilitate the gradual grinding of material particles into finer particles or to control the size of the grinding particles.

[0018] A further improvement of the technical solution of the present invention is that: the grinding assembly further includes two sets of arc-shaped scrapers, the two sets of arc-shaped scrapers are fixedly connected to the two sides of the rotating rod, the two sets of arc-shaped scrapers are respectively fixedly connected to the two sides of the outer wall of the rotating rod, and the end of the arc-shaped scraper away from the rotating rod is slidably connected to the inner wall of the grinding box, and a row of combing grooves is respectively opened at the end of the two sets of arc-shaped scrapers near the inner wall of the grinding box.

[0019] The above technical solution involves setting an arc-shaped scraper on the outer wall of the rotating rod. This allows the arc-shaped scraper to rotate as it moves, scraping away the material adhering to the inner wall of the grinding chamber. Furthermore, the addition of a combing groove allows the material particles to be broken up and turned over while the arc-shaped scraper is moving, resulting in more thorough grinding and improved grinding efficiency.

[0020] A further improvement of the technical solution of the present invention is that: the contact position between the mixing box and the grinding box on the outer wall of the connecting pipe is a sliding connection, and a sieve plate is fixedly connected to the top of the connecting pipe.

[0021] By adopting the above technical solution, the solution can intercept larger particles by setting up a sieve plate to facilitate the screening of the corresponding grinding particles, so as to avoid affecting the quality of the mortar produced by mixing.

[0022] A further improvement of the technical solution of the present invention is that: push plates are fixedly connected to both sides of the outer wall of the connecting pipe, and two rows of springs are fixedly connected to the bottom of the two push plates and the top of the mixing tank.

[0023] The above technical solution supports the push plate by setting the tension of the spring, which facilitates the upward pushing of the screen plate by the spring tension and the downward pressing of the screen plate by the grinding roller and the arc scraper. This causes the screen plate to vibrate, which can prevent the screen plate from clogging. Moreover, the vibrating screen plate can also improve the screening efficiency, allowing material particles to pass through quickly.

[0024] A further improvement of the technical solution of the present invention is that: two connecting rods are fixedly connected to the two sides of the bottom of the connecting pipe respectively; two sets of arc-shaped floats are respectively provided on the two sides of the inner wall of the mixing tank, and the arc-shaped floats are fixedly connected to the connecting rods at the corresponding positions; two mixing plates are provided inside the mixing tank, and the two mixing plates are arranged vertically and fixedly connected to the outer wall of the connecting rods at the corresponding positions; a row of strip grooves for the mortar to move up and down is opened on the inner wall of the mixing plate.

[0025] The above technical solution connects the mixing plate to the bottom of the connecting pipe by setting a connecting rod. When the grinding roller and the arc-shaped scraper pass by, they press down on the connecting pipe, causing the mixing plate to sink. This action is combined with the buoyancy of the arc-shaped float to lift the mixing plate. The mixing plate sinks and floats, causing the mortar to move up and down through the strip groove in the mixing box. This ensures that the mortar is thoroughly mixed, thereby improving the preparation efficiency.

[0026] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows:

[0027] 1. This invention provides lightweight thermal insulation composite mortar and its production equipment. By setting injection pipes on both sides of the top of the mixing tank, the mixture can be more evenly mixed on the inner wall of the mixing tank. Materials are added through the feed inlet, and the direct drive motor drives the rotating rod to rotate, which in turn drives the grinding roller to roll on the inner wall of the grinding tank. Due to the circular motion trajectory, the grinding roller can repeatedly crush and grind the materials in the grinding tank, making the material particles smaller, which improves the effect of subsequent mortar mixing and avoids uneven mixing. The distance between the grinding roller and the inner wall of the grinding tank can be adjusted by the extension and retraction of the electric telescopic plate, so as to gradually grind the material particles into smaller particles or control the size of the ground particles. By setting an arc-shaped scraper on the outer wall of the rotating rod, the rotating rod drives the arc-shaped scraper to rotate, so that the arc-shaped scraper scrapes off the material adhering to the inner wall of the grinding tank when it moves. In addition, the combing groove can disperse and turn the material particles while the arc-shaped scraper moves, so as to make the grinding more thorough and improve the grinding effect.

[0028] 2. This invention provides lightweight thermal insulation composite mortar and its production equipment. By setting a sieve plate to facilitate the screening of corresponding ground particles, larger particles can be intercepted to avoid affecting the quality of the mixed mortar. By setting the spring tension to support the push plate, the upward movement of the sieve plate by the spring tension and the downward movement of the grinding roller and the arc scraper when passing by can be coordinated to make the sieve plate vibrate. This can prevent the sieve plate from clogging, and the vibrating sieve plate can also improve the screening efficiency, allowing material particles to pass through quickly.

[0029] 3. This invention provides lightweight thermal insulation composite mortar and its production equipment. By setting a connecting rod to connect a mixing plate below the connecting pipe, the grinding roller and the arc-shaped scraper press down on the connecting pipe, causing the mixing plate to sink. This action, combined with the buoyancy of the arc-shaped float, lifts the mixing plate up and down, causing the mortar to move up and down through the strip groove in the mixing box. This ensures that the mortar is fully mixed, thereby improving the preparation efficiency. Attached Figure Description

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0038] Example 1

[0039] This invention provides a lightweight thermal insulation composite mortar, comprising: 35-40 parts cement, 8-12 parts converter slag granules, 12-18 parts reinforcing material, 16-22 parts composite thermal insulation aggregate, 0.25-0.35 parts resin-type redispersible latex powder, 0.6-0.9 parts cold-water type polyvinyl alcohol, 0.1-0.2 parts hydroxypropyl methylcellulose ether, 0.01-0.03 parts air-entraining agent, 0.06-0.1 parts water glass, 0.005-0.01 parts inorganic retarder, 8-13 parts polystyrene granules, 30-50 parts vitrified microspheres, 1-2 parts redispersible latex powder, and 0.2-0.6 parts water-retaining agent.

[0040] In this embodiment, by incorporating a water-retaining agent, the volume of the mortar can be prevented from shrinking as water evaporates. During the shrinkage process, if the cement-containing material has no strength or very low strength, the shrinkage stress is greater than the tensile strength of the material, and the shrinkage will manifest as a problem of relatively concentrated large cracks.

[0041] Example 2

[0042] like Figure 1 , 2As shown in Figures 3 and 4, based on Embodiment 1, the present invention provides a lightweight thermal insulation composite mortar production equipment, including a mixing tank 1. A grinding tank 2 is disposed above the top of the mixing tank 1, and the two sides of the grinding tank 2 are fixedly connected to the top of the mixing tank 1 through support plates 21. A discharge port 11 for discharging mortar is fixedly installed at the bottom of the front of the mixing tank 1. Liquid injection pipes 12 for injecting mixed liquid are fixedly installed on both sides of the top of the mixing tank 1. A feed port 22 for adding materials is fixedly installed at the top of the grinding tank 2. A grinding component 24 for grinding materials is disposed on the inner wall of the grinding tank 2. A direct drive motor 23 for driving the grinding component 24 is fixedly installed on the back of the grinding tank 2. The mixing tank 1 and the grinding tank 2 are connected by a connecting pipe. 25. This scheme, by setting injection pipes 12 on both sides of the top of the mixing tank 1, facilitates more uniform mixing of the mixture on the inner wall of the mixing tank 1. The grinding assembly 24 includes a rotating rod 241, which is rotatably connected to the inner wall of the grinding box 2. One end of the rotating rod 241 is fixedly connected to the output end of the direct drive motor 23. Support frames 242 are respectively set on both sides of the rotating rod 241. Grinding rollers 243 are rotatably connected to the inner walls of the two sets of support frames 242 through rotating shafts. The grinding rollers 243 are rolled in contact with the inner wall of the grinding box 2. In this scheme, materials are added through the feed inlet 22, and the rotating rod 241 is driven to rotate by starting the direct drive motor 23, so that the rotating rod 241 drives the grinding rollers 243 to grind. The grinding roller 243 rolls along the inner wall of the grinding box 2, and due to its circular motion, it can repeatedly crush and grind the material inside the grinding box 2, turning the material particles into finer particles. This facilitates the subsequent mixing and mortar preparation, preventing uneven mixing. An electric telescopic plate 244 is fixedly installed between the outer wall of the rotating rod 241 and the two sets of support frames 242. This design allows for adjustment of the distance between the grinding roller 243 and the inner wall of the grinding box 2 by extending and retracting the electric telescopic plate 244, so as to gradually grind the material particles into finer particles or control the size of the grinding particles. The grinding assembly 24 also includes two sets of arc-shaped scrapers 245, which are fixedly connected to the rotating rod 241. On both sides of the rod 241, two sets of arc-shaped scrapers 245 are fixedly connected to the outer walls of the rotating rod 241. The end of the arc-shaped scraper 245 away from the rotating rod 241 is slidably connected to the inner wall of the grinding box 2. A row of combing grooves 246 are opened at the end of the two sets of arc-shaped scrapers 245 near the inner wall of the grinding box 2. This solution, by setting the arc-shaped scrapers 245 on the outer wall of the rotating rod 241, facilitates the rotation of the arc-shaped scrapers 245 by the rotating rod 241. When the arc-shaped scrapers 245 move, they will scrape off the material adhering to the inner wall of the grinding box 2. In addition, by setting the combing grooves 246, the material particles can be broken up and turned over while the arc-shaped scrapers 245 are moving, so that the grinding is more thorough and the grinding effect can be improved.

[0043] In this embodiment, by setting injection pipes 12 on both sides of the top of the mixing tank 1, the mixture can be more evenly mixed on the inner wall of the mixing tank 1. Materials are added through the feed inlet 22, and the direct drive motor 23 drives the rotating rod 241 to rotate. This allows the rotating rod 241 to drive the grinding roller 243 to roll on the inner wall of the grinding tank 2. Due to the circular motion, the grinding roller 243 can repeatedly crush and grind the materials in the grinding tank 2, making the material particles finer. This improves the effect of subsequent mortar mixing and avoids uneven mixing. The extension and retraction of the electric telescopic plate 244 can adjust the distance between the grinding roller 243 and the inner wall of the grinding box 2, so as to facilitate the gradual grinding of material particles into finer particles, or to control the size of the grinding particles. By setting an arc-shaped scraper 245 on the outer wall of the rotating rod 241, the arc-shaped scraper 245 can be rotated by the rotating rod 241, so that the arc-shaped scraper 245 will scrape off the material adhering to the inner wall of the grinding box 2 when it moves. Furthermore, by setting a combing groove 246, the material particles can be broken up and turned over while the arc-shaped scraper 245 moves, so that the grinding is more thorough and the grinding effect can be improved.

[0044] Example 3

[0045] like Figure 1 , 3 As shown in Figure 5, based on Embodiment 1, the present invention provides a technical solution: Preferably, the contact position between the outer wall of the connecting pipe 25 and the mixing box 1 and the grinding box 2 is a sliding connection, and a sieve plate 251 is fixedly connected to the top of the connecting pipe 25. This solution uses the sieve plate 251 to facilitate the screening of the corresponding grinding particles, and can intercept larger particles to avoid affecting the quality of the mortar produced by mixing. Push plates 252 are fixedly connected to both sides of the outer wall of the connecting pipe 25. Two rows of springs 253 are fixedly connected between the bottom of the two push plates 252 and the top of the mixing box 1. This solution uses the tension of the springs 253 to support the push plates 252, so that the upward pushing of the sieve plate 251 by the tension of the springs 253 and the downward pressing of the sieve plate 251 when the grinding roller 243 and the arc scraper 245 pass by can be coordinated, so that the sieve plate 251 vibrates, which can avoid the sieve plate 251 from clogging. Moreover, the vibrating sieve plate 251 can also improve the screening efficiency, so that the material particles can pass through quickly.

[0046] In this embodiment, by setting a sieve plate 251 to facilitate the screening of corresponding grinding particles, larger particles can be intercepted to avoid affecting the quality of the mixed mortar. By setting the tension of the spring 253 to support the push plate 252, the action of pushing the sieve plate 251 upward by the tension of the spring 253 and the action of pressing the sieve plate 251 downward when the grinding roller 243 and the arc scraper 245 pass by can be coordinated to make the sieve plate 251 vibrate. This can prevent the sieve plate 251 from clogging, and the vibrating sieve plate 251 can also improve the screening efficiency, allowing material particles to pass through quickly.

[0047] Example 4

[0048] like Figure 1 , 3 As shown in Figure 6, based on Embodiment 1, the present invention provides a technical solution: Preferably, two connecting rods 3 are fixedly connected to both sides of the bottom of the connecting pipe 25, and two sets of arc-shaped floats 31 are respectively provided on both sides of the inner wall of the mixing tank 1, and the arc-shaped floats 31 are fixedly connected to the connecting rods 3 at the corresponding positions. Two mixing plates 32 are provided inside the mixing tank 1, and the two mixing plates 32 are arranged vertically and fixedly connected to the outer wall of the connecting rods 3 at the corresponding positions. A row of strip grooves 321 for the mortar to move up and down is opened on the inner wall of the mixing plate 32. This solution connects the mixing plates 32 to the connecting pipe 25 by setting the connecting rods 3 below the connecting pipe 25. When the grinding roller 243 and the arc-shaped scraper 245 pass by, they press down on the connecting pipe 25 and drive the mixing plates 32 to sink. Combined with the buoyancy of the arc-shaped floats 31 to lift the mixing plates 32, the mixing plates 32 sink and float up and down, so that the mortar moves up and down in the mixing tank 1 through the strip grooves 321, so that the mortar can be fully mixed, thereby improving the preparation efficiency.

[0049] In this embodiment, by setting the connecting rod 3 to connect the stirring plate 32 below the connecting pipe 25, the grinding roller 243 and the arc-shaped scraper 245 press down on the connecting pipe 25 to drive the stirring plate 32 to sink, and the buoyancy of the arc-shaped float 31 lifts the stirring plate 32 to rise. The stirring plate 32 sinks and rises, so that the mortar moves up and down in the mixing box 1 through the strip groove 321, so that the mortar can be fully mixed, thereby improving the preparation efficiency.

[0050] The working principle of lightweight thermal insulation composite mortar and its production equipment will be explained in detail below.

[0051] like Figure 1-6As shown, by setting injection pipes 12 on both sides of the top of the mixing tank 1, the mixture can be more evenly mixed on the inner wall of the mixing tank 1. Materials are added through the feed inlet 22, and the direct drive motor 23 drives the rotating rod 241 to rotate. This allows the rotating rod 241 to drive the grinding roller 243 to roll on the inner wall of the grinding tank 2. Due to the circular motion, the grinding roller 243 can repeatedly crush and grind the materials in the grinding tank 2, making the material particles finer. This improves the effect of subsequent mixing and mortar preparation, and avoids... To prevent uneven mixing, the distance between the grinding roller 243 and the inner wall of the grinding chamber 2 can be adjusted by extending and retracting the electric telescopic plate 244. This allows for the gradual grinding of material particles into finer particles or control of particle size. An arc-shaped scraper 245 is installed on the outer wall of the rotating rod 241, which rotates as the rod moves. As the scraper moves, it removes material adhering to the inner wall of the grinding chamber 2. Furthermore, a combing groove 246 can further agitate the material particles while the scraper 245 is moving. The particles are broken up and agitated to ensure more thorough grinding, thus improving the grinding effect. A sieve plate 251 is used to screen the particles, intercepting larger particles to prevent them from affecting the quality of the mixed mortar. The tension of a spring 253 supports the push plate 252, facilitating the upward movement of the sieve plate 251 and the downward movement of the grinding roller 243 and the arc-shaped scraper 245 as they pass. This causes the sieve plate 251 to vibrate, preventing it from shaking. In case of blockage, the shaking screen plate 251 can also improve the screening efficiency, allowing material particles to pass through quickly. By setting the connecting rod 3 to connect the stirring plate 32 below the connecting pipe 25, the grinding roller 243 and the arc scraper 245 press down on the connecting pipe 25 to drive the stirring plate 32 to sink. Combined with the buoyancy of the arc float plate 31 to lift the stirring plate 32, the stirring plate 32 sinks and floats, causing the mortar to move up and down in the mixing box 1 through the strip groove 321, so that the mortar can be fully mixed to improve the preparation efficiency.
