Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dry-mix mortar production, in particular to a dry-mix mortar production device. Background Art
[0002] Dry-mix mortar is a pre-mixed building material. It requires cementitious materials, fine aggregates, admixtures, additives, and other components determined by performance, to be mixed in a dry state according to a certain mix ratio to form a mortar in granular or powdered sand. Dry-mix mortar is transported to the construction site in bagged or bulk form and can be used directly after adding water and mixing. Compared to on-site mortar made by mixing sand, cement, and other additives with water, dry-mix mortar has a relatively fixed location, a complete set of machinery and equipment, precise measurement, and a complete quality control and supervision management system, which ensures the production quality of dry-mix mortar. Moreover, at the construction site, it only needs to add an appropriate amount of water and stir evenly before it can be used directly. For this reason, dry-mix mortar has little pollution to the on-site environment and is environmentally friendly and reliable, making dry-mix mortar have obvious social benefits.
[0003] The main production techniques for dry-mix mortar include weighing and mixing. This involves weighing raw materials, admixtures, additives, and other components determined by performance according to the mix ratio in a metering system. These raw materials, admixtures, additives, and other components determined by performance according to the mix ratio are then transported to the mixing system for mixing, resulting in dry-mix mortar. Commonly used weighing methods in dry-mix mortar production include screw metering and subtraction metering. Screw metering uses the number of revolutions of the metering screw to determine the output volume of the screw conveyor, thereby measuring the conveying volume. However, due to gaps between particles, relying solely on the number of revolutions of the metering screw to calculate the output volume can result in significant errors, which may not meet the requirements in production environments requiring high precision. Subtractive metering uses a subtractive metering scale to sequentially measure the dry-mix mortar components, admixtures, and additives delivered to a metering tank. Automatically opening and closing valves located below the metering tank control the delivery of the measured raw materials, admixtures, and additives to the mixing system. While this metering method avoids interference from interparticle gaps, the valve installed on the metering tank only controls the opening and closing of the discharge port, not the delivery rate, making it difficult to ensure stable delivery. Furthermore, a coulter mixer is a common piece of equipment in dry-mix mortar production. It primarily consists of a barrel, coulters, flying cutters, and a transmission mechanism. A rotating mechanism drives the coulters and flying cutters, causing the material to move circumferentially along the barrel wall. As the material flows through the flying cutters, it is thrown by the high-speed rotating cutters, achieving uniform mixing in a relatively short period of time. To facilitate the use of the flying cutters for material throwing, the cutters should be mounted slightly below the center of the barrel, allowing the coulters to easily push the material toward them. However, due to the low installation position of the fly cutter, cleaning and maintenance of the fly cutter are relatively more difficult. Therefore, there is still room for improvement in the transportation, cleaning and maintenance of dry-mix mortar production equipment, so as to better promote the application and popularization of dry-mix mortar production equipment.

By loading and unloading the fixing plate 12, it is convenient to load and unload the second motor 11 and the flying cutter 10, so that the flying cutter 10 and the second motor 11 can be cleaned or maintained. Since the fixing groove 12 is set at an angle, the material entering the gap between the fixing plate 12 and the cylinder 6 falls back into the cylinder 6 under the action of gravity to prevent the material from leaking out of the gap between the fixing plate 12 and the cylinder 6.
[0024] In this embodiment, two scrapers 13 are obliquely arranged on the rotating shaft 7, and the two scrapers 13 are both located in the cylinder 6. The two scrapers are respectively located on both sides of the rotating shaft 7, and several plows 9 are located between the two scrapers 13. The angle between the two scrapers 13 is 90°-150°, so that the scrapers 13 are used to conveniently push the materials on both sides of the inner cavity of the cylinder 6 toward the middle part of the cylinder 6, so that the plow 9 drives the materials to move circumferentially along the inner wall of the cylinder 6. Support shafts 14 are respectively provided between the scraper 13 and the rotating shaft 7 and between the plow 9 and the rotating shaft 7.

The scraper sleeve 15 is installed on the scraper 13 by screws, so that the scraper sleeve 15 and the end of the cylinder 6 are used for scraping, thereby avoiding the accumulation of material at the end of the cylinder 6, thereby improving the material mixing effect.
[0026] Please refer again Figure 1 and 5 , the top of the cylinder 6 is provided with a support plate 16, and a feed pipe 17 is embedded on the support plate 16. The feed pipe 17 is connected to the cylinder 6, and the feed pipe 17 and the discharge end of the screw conveyor 2 are respectively provided with a first flange 18.

The strip 21 is movably fitted in the slot 19. The strip 21 The shape of the cover 20 matches the shape of the inner cavity of the slot 19, and the side of the cover 20 away from the support plate 16 and the two ends of the support plate 16 are respectively installed on the top of the cylinder 6 by screws, thereby sealing the top of the cylinder 6 to prevent the material from spilling out from the top of the cylinder 6 and preventing dust from flowing into the cylinder 6 from the top of the cylinder 6. In addition, the slot 19 provided on the support plate 16 and the insertion strip 21 provided on the cover 20 can limit one side of the cover 20, and then the other side of the cover 20 is installed on the cylinder 6 by screws, so as to fix the cover 20 to the top of the cylinder 6. Moreover, when the inner cavity of the cylinder 6 needs to be cleaned or maintained, it is only necessary to remove the cover 20 to open part of the top of the cylinder 6, thereby avoiding the need to disassemble the connection of the screw conveyor 2, thereby simplifying the difficulty of cleaning or maintaining the inner cavity of the cylinder 6. It should be noted that a discharge pipe is embedded in the bottom end of the cylinder 6, and the discharge pipe is connected to the cylinder 6. The valve provided on the discharge pipe is opened and closed by the switch cover to facilitate the control of the discharge of material from the cylinder 6.
[0027] Specifically, handles 22 are provided on both sides of the cover 20 . The handles 22 are of an N-shaped rod structure. The bottom ends of the handles 22 are mounted on the top surface of the cover 20 to facilitate loading and unloading of the cover 20 .
[0028] In this embodiment, a frame 23 is provided on the outside of the cylinder 6, and the cylinder 6 is installed on the top of the frame 23. Bearing seats 24 are respectively provided on both sides of the cylinder 6. The rotating shaft 7 is rotatably mounted on the bearing seat 24, and the bearing seat 24 is installed on the frame 23. Perforations are respectively provided on both sides of the cylinder 6, and the two sides of the rotating shaft 7 are respectively movable on the perforations. The aperture of the perforation coincides with the diameter of the rotating shaft 7. A sealing ring or other sealing component is provided between the rotating shaft 7 and the perforation to prevent the material from leaking from the gap between the rotating shaft 7 and the perforation. The first motor 8 is connected to one end of the rotating shaft 7 through a coupling, and the first motor 8 is installed on the frame 23, so that the cylinder 6 and the first motor 8 are respectively fixed using the frame 23, so that the first motor 8 can be used to drive the rotating shaft 7 and the plow 9 to stir and mix the material in the cylinder 6.
[0029] Please refer again Figure 1 and 2 The material tank 1 is provided with a fixing ring 25, the inner ring of the fixing ring 25 is installed on the outer wall of the material tank 1, the weighing end of the weighing sensor 4 is installed on the fixing ring 25, and the bottom of the weighing sensor 4 is installed on the bracket 3 to facilitate weighing and measuring the material tank 1. The two ends of the star-shaped discharger 5, the feeding end of the screw conveyor 2 and the bottom end of the material tank 1 are respectively provided with a second flange 26. The two ends of the star-shaped discharger 5 are respectively connected to the screw conveyor 2 and the material tank 1 through the second flange 26 to facilitate the connection between the star-shaped discharger 5 and the screw conveyor 2 or the material tank 1 for loading and unloading.
[0030] The method of using this product is as follows: Figures 1 to 7 As shown, first, the cementitious material, fine aggregate, admixture, additives and other components determined by performance are sequentially transported into the material tank 1 through the conveying equipment. The materials added to the material tank 1 are weighed according to the value fed back by the weighing sensor 4. When the weight of the materials in the material tank 1 meets the mixing ratio requirements, the above-mentioned conveying equipment is closed, and the screw conveyor 2 and the star-shaped discharger 5 are started to transport the materials in the material tank 1 into the cylinder 6; then, the first motor 8 and the second motor 11 are started respectively to drive the roller 7, the plow 9, the flying knife 10 and the scraper 13, so that the materials in the cylinder 6 are driven by the plow 9 to move circumferentially along the inner wall of the cylinder 6. The materials on both sides of the cylinder 6 are pushed toward the plow 9 by the scraper 13, and when the materials flow through the flying knife 10, the materials are thrown by the high-speed rotating flying knife 10, thereby achieving the purpose of uniformly mixing the materials in a relatively short time. Finally, after the materials are mixed, the valve body set at the bottom end of the cylinder 6 is opened to discharge the uniformly mixed materials to meet the mixing requirements of the dry-mixed mortar. In addition, it should be noted that while the material is being transported from the material tank 1 toward the cylinder 6, the changes in the value fed back by the weighing sensor 4 are observed, and the value fed back by the weighing sensor 4 will no longer change, that is, after the material transportation is completed, the screw conveyor 2 and the star-shaped discharger 5 are turned off, and the cementitious material, fine aggregate, admixture, additive and other components determined according to the performance are transported to the material tank 1 in sequence through the conveying equipment again, so that the metering operation and the mixing operation can be carried out simultaneously to ensure the production efficiency of the dry-mixed mortar.
[0031] It should be noted that in order to ensure the production quality of dry-mixed mortar, this product should be cleaned regularly. Since the outer surface of this product is exposed to the outside, it is relatively easy to clean the outer surface of this product, so it will not be explained here. Since there is no movable machinery in the inner cavity of the material tank 1, it is only necessary to clean the inner wall of the material tank 1 to complete the cleaning of the inner cavity of the material tank 1. When cleaning the inner cavity of the screw conveyor 2, it is necessary to take out the spiral blades, clean the inner wall and spiral blades of the screw conveyor 2 respectively, and complete the cleaning of the inner cavity of the screw conveyor 2. However, when cleaning the inner cavity of the cylinder 6, the fixed plate 12 is removed to clean the flying knife 10. At the same time, the upper and lower sides of the cylinder 6 are opened through the fixed groove opened in the cylinder 6 and the cover 20 is removed from the cylinder 6, so that the inside of the cylinder 6 can be cleaned.
[0032] In this embodiment, the weighing sensor 4 is provided to weigh the material tank 1, so as to facilitate the measurement of the material added to the material tank 1. A star-shaped discharger 5 is provided between the material tank 1 and the screw conveyor 2 to control the efficiency of conveying the material in the material tank 1 to the screw conveyor 2. In addition, in this embodiment, the first motor 8 and the second motor 11 are provided to drive the plow 9 and the flying cutter 10 to operate, so that the material in the cylinder 6 moves circumferentially along the inner wall of the cylinder 6 under the drive of the plow 9. When the material flows through the flying cutter 10, the material is thrown by the high-speed rotating flying cutter 10, thereby achieving the purpose of uniformly mixing the material in a relatively short time. By loading and unloading the fixing plate 12, the second motor 11 and the flying cutter 10 can be easily loaded and unloaded, so that the flying cutter 10 and the second motor 11 can be cleaned or maintained. Since the fixing groove is inclined, the material entering the gap between the fixing plate 12 and the cylinder 6 falls back into the cylinder 6 under the action of gravity, so as to prevent the material from leaking out of the gap between the fixing plate 12 and the cylinder 6.
[0033] The embodiments described above are only preferred embodiments of the present invention and do not limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structure, features and principles described in the patent scope of the present invention should be included in the scope of the patent application of the present invention.
