Description

Technical Field

[0001] This utility model relates to the field of raw material proportioning technology, and in particular to a grouting material proportioning device for sealing leaks. Background Technology

[0002] In building construction, tunnel construction, and water conservancy projects, structural leakage can jeopardize the safety and durability of the project. Leak sealing is a key step in ensuring the normal operation of the project, and leak sealing grouting materials are highly effective in sealing gaps and enhancing the airtightness of structures.

[0003] In most existing devices, raw materials are directly poured in, and the raw materials usually contain impurities such as gravel or lumps. When the raw materials are poured into the mixing hopper, the gravel or lumps will also enter the mixing hopper, which can easily reduce the quality of the batching. Therefore, a raw material proportioning device for grouting material production is proposed.

[0004] An existing patent (publication number: CN218659806U) discloses a raw material proportioning device for grout production, relating to the field of grout production technology. It addresses the problem that when raw materials are poured into a mixing hopper, impurities such as crushed stone or lumps also enter the hopper, easily reducing the quality of the batching. The device includes a mixing hopper and a support plate positioned above it. Both sides of the top of the support plate are fixedly mounted with batching hoppers. A filter screen is installed inside each batching hopper. Supports are installed on both sides of the top of the mixing hopper, and conveyor belts are mounted on both supports. The supports are located below the batching hopper. An inlet is opened at one end of the conveyor belt on the top of the mixing hopper. This application, through the arrangement of the batching hopper, filter screen, and conveyor belt, allows the raw materials to be poured into the batching hopper first, enabling the filter screen to filter out impurities, thereby reducing the amount of impurities entering the mixing hopper and improving the quality of the batching.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, most existing devices discharge the material after the mixing process is complete. The mixed grout has a certain viscosity and will adhere to the inner wall of the mixing tank, which not only affects the mixing quality but also causes some residue and waste. Furthermore, it is generally impossible to effectively clean the inside of the mixing tank after discharging the material.

[0006] To address this, a grout mixing device for sealing leaks is proposed. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A grouting material mixing device includes a mixing tank 1, four connecting columns 2 are bolted to the top of the mixing tank 1, a placement plate 3 is bolted between the tops of the connecting columns 2, four raw material boxes 4 are provided on the top of the placement plate 3, a rotating shaft 5 is rotatably connected inside the mixing tank 1, a mixing rod 6 is bolted to both sides of the rotating shaft 5, a wall scraping mechanism 7 is provided inside the mixing tank 1, and a cleaning mechanism 8 is provided inside the wall scraping mechanism 7.

[0029] The wall scraping mechanism 7 includes a first upper scraper 71, a second upper scraper 72, a first lower scraper 73, and a second lower scraper 74. The right side of the first upper scraper 71 and the left side of the second upper scraper 72 are respectively bolted to the top two sides of the surface of the rotating shaft 5. The right side of the first lower scraper 73 and the left side of the second lower scraper 74 are respectively bolted to the bottom two sides of the surface of the rotating shaft 5. The sides of the first upper scraper 71, the second upper scraper 72, the first lower scraper 73, and the second lower scraper 74 closest to the inner wall of the mixing tank 1 are respectively in sliding contact with the inner wall of the mixing tank 1.

[0030] In this embodiment: In the building leak-sealing grouting operation, the leak-sealing grout mixing device is first set up. A suitable mixing tank 1 is selected, and four connecting columns 2 are bolted to the top of the mixing tank 1. Then, a placement plate 3 is bolted between the tops of the connecting columns 2 to provide a stable support platform for the four raw material boxes 4 to be installed later. Each raw material box 4 can store different types of leak-sealing grout raw materials such as cement and additives. Then, these raw materials are mixed and put into the mixing tank 1. A flexible rotating shaft 5 is installed inside the mixing tank 1, and a stirring rod 6 is bolted to both sides of the rotating shaft 5. The rotation of the rotating shaft 5 causes the stirring rod 6 to fully mix the raw materials in the tank. At the same time, The wall scraping mechanism 7 attaches the first upper scraper 71 and the second upper scraper 72 to the top two sides of the surface of the rotating shaft 5, and the first lower scraper 73 and the second lower scraper 74 to the bottom two sides of the surface of the rotating shaft 5. The scrapers are arranged so that the side closest to the inner wall of the mixing tank 1 slides in contact with the inner wall of the mixing tank 1. During mixing, as the rotating shaft 5 rotates, these scrapers can scrape off the raw materials attached to the tank wall, ensuring uniform mixing and preventing the accumulation of raw materials from affecting the proportion and mixing effect. After the mixing work is completed and the mixed materials are discharged, the inside of the mixing tank 1 can be sprayed with water to clean it through the cleaning mechanism 8, providing a good internal environment for the next mixing.

[0031] Specifically, such as Figure 3 As shown, the cleaning mechanism 8 includes a connecting groove 81, a connecting hole 82, and two water injection grooves 83. The connecting groove 81 is opened at the top inside the rotating shaft 5, and the connecting hole 82 is opened at the top inside the rotating shaft 5. The bottom of the connecting groove 81 is fixedly connected to the top of the connecting hole 82. The water injection grooves 83 are respectively opened inside the first upper scraper 71 and the second upper scraper 72, and the side of the water injection groove 83 near the connecting hole 82 is fixedly connected to the connecting hole 82.

[0032] Specifically, such as Figure 3 As shown, the front, rear and top sides of the first upper scraper 71 and the second upper scraper 72 are provided with a number of water outlet holes 84, and the side of the water outlet hole 84 near the water injection tank 83 is fixedly connected to the water injection tank 83. The inside of the water outlet hole 84 is provided with a housing 85.

[0033] Specifically, such as Figure 3 As shown, a clogging cover 86 is provided on the side of the housing 85 away from the water injection tank 83. Two connecting blocks 87 are bolted to the side of the clogging cover 86 near the housing 85, and the surface of the connecting blocks 87 slides in contact with the inner wall of the housing 85. A moving rod 88 is bolted to the opposite side of the connecting blocks 87. A fixed rod 89 is bolted to the inside of the housing 85 near the water injection tank 83. A spring 810 is connected between the moving rod 88 and the fixed rod 89.

[0034] In this embodiment: After the mixing operation is completed, the inside of the mixing tank 1 needs to be cleaned to ensure its cleanliness for the next use. At this time, clean water is injected into the connecting groove 81. Since the bottom of the connecting groove 81 is fixedly connected to the top of the connecting hole 82, the cleaning water flows from the connecting groove 81 into the connecting hole 82. The connecting hole 82 is fixedly connected to the water injection grooves 83 respectively opened inside the first upper scraper 71 and the second upper scraper 72, so the cleaning water further flows into the water injection grooves 83. As the water pressure in the water injection groove 83 increases, the water pressure... The elastic force of the spring 810 pushes the connecting block 87, which is connected to the moving rod 88, to slide on the inner wall of the housing 85, thereby opening the anti-clogging cover 86. At this time, the cleaning water in the water injection tank 83 flows out through the water outlet 84, which is fixedly connected to the water injection tank 83, to clean the inside of the mixing tank 1. When the cleaning is completed, the supply of cleaning water stops, the water pressure in the water injection tank 83 decreases, the spring 810 returns to its elastic deformation, pulls the moving rod 88 and the connecting block 87, and resets the anti-clogging cover 86 to prevent debris from entering the water outlet 84 and causing blockage, thus preparing for the next cleaning.

[0035] Specifically, such as Figure 2 As shown, a first vertical scraper 9 is bolted between the left sides of the first upper scraper 71 and the first lower scraper 73, and the side of the first vertical scraper 9 closest to the inner wall of the mixing tank 1 is in sliding contact with the mixing tank 1.

[0036] Specifically, such as Figure 2 As shown, a second vertical scraper 10 is bolted between the right sides of the second upper scraper 72 and the second lower scraper 74, and the side of the second vertical scraper 10 closest to the inner wall of the mixing tank 1 is in sliding contact with the mixing tank 1.

[0037] In this embodiment: During the mixing process of the mixing tank 1, in order to more thoroughly scrape off the raw materials on the inner wall of the mixing tank 1, a first vertical scraper 9 is bolted between the left side of the first upper scraper 71 and the first lower scraper 73, and a second vertical scraper 10 is bolted between the right side of the second upper scraper 72 and the second lower scraper 74. The first vertical scraper 9 and the second vertical scraper 10 are allowed to slide in contact with the mixing tank 1 on the side closest to the inner wall of the mixing tank 1. When the rotating shaft 5 rotates, the first vertical scraper 9 and the second vertical scraper 10 rotate together with the other parts of the wall scraping mechanism 7. They can perform vertical scraping operations on the inner wall of the mixing tank 1. Together with the first upper scraper 71, the second upper scraper 72, the first lower scraper 73 and the second lower scraper 74, they form a three-dimensional wall scraping system, which more effectively removes the raw materials attached to various parts of the inner wall of the mixing tank 1, and further improves the uniformity and effect of the mixing.

[0038] Specifically, such as Figure 4 , Figure 5As shown, four support legs 11 are bolted to the bottom of the mixing tank 1, and a material collection hopper 12 is provided on the top of the mixing tank 1. The bottom of the material collection hopper 12 is fixedly connected to the top of the mixing tank 1. A discharge port 13 is provided on the top of the raw material box 4, and four pressure sensors 14 are bolted to the bottom of the raw material box 4. The bottom of the pressure sensors 14 is respectively bolted to the top of the placement plate 3.

[0039] Specifically, such as Figure 4 , Figure 5 As shown, the interior of the placement tray 3 has several through holes 15. The bottom of the raw material box 4 is fixedly connected to a first discharge pipe 16. The bottom of the first discharge pipe 16 extends into the interior of the collection hopper 12. An electric ball valve 17 is installed inside the first discharge pipe 16. A motor 18 is bolted to the bottom of the mixing tank 1. The output shaft of the motor 18 extends into the interior of the mixing tank 1 and is bolted to a rotating shaft 5. The top of the rotating shaft 5 extends to the top of the mixing tank 1 and is fixedly connected to an anti-winding rotary joint 19. A water supply pipe 20 is fixedly connected to the top of the anti-winding rotary joint 19. A second discharge pipe 21 is installed at the bottom of the mixing tank 1.

[0040] In this embodiment: First, four support legs 11 are bolted to the bottom of the mixing tank 1 to ensure the stability of the device, and a collection hopper 12 fixedly connected to the tank body is installed on its top; then, a raw material box 4 is prepared, with a discharge port 13 on its top, and four pressure sensors 14 are bolted to the bottom, with the bottom of the sensors connected to the top of the placement plate 3 respectively. Several through holes 15 are opened in the placement plate 3, allowing the first discharge pipe 16, which is fixedly connected to the bottom of the raw material box 4 and equipped with an electric ball valve 17, to extend into the collection hopper 12 through the through holes 15; then, a motor 18 is bolted to the bottom of the mixing tank 1, so that the output shaft of the motor 18 extends into the tank and is bolted to the rotating shaft 5, and the top of the rotating shaft 5 extends to the top of the mixing tank 1 and is fixedly connected to the anti-winding rotary joint 19, and then the top of the joint is... The mixing tank 1 is fixedly connected to the water supply pipe 20. At the same time, a second discharge pipe 21 is set at the bottom of the mixing tank 1 to discharge the mixed grouting material. In use, the grouting material is first added through the discharge port 13 at the top of the raw material box 4. According to the mixing ratio requirements and the weight data fed back by the pressure sensor 14, the electric ball valve 17 in the corresponding first discharge pipe 16 is opened, so that the raw material flows into the collection hopper 12 through the first discharge pipe 16 and then into the mixing tank 1. The motor 18 is started to drive the rotating shaft 5 to rotate and stir the raw material. After the stirring is completed, the mixed grouting material is discharged from the second discharge pipe 21 for operation. If it is necessary to clean the mixing tank 1, the water supply pipe 20 can be used to deliver cleaning water into the tank through the anti-winding rotary joint 19, and the cleaning mechanism 8 can be used for cleaning.

[0041] Working principle: First, add the sealing grout material through the discharge port 13 at the top of the raw material box 4. According to the mixing ratio requirements and based on the raw material weight data fed back by the pressure sensor 14, open the electrically controlled ball valve 17 in the corresponding first discharge pipe 16, so that the raw material flows into the collection hopper 12 through the first discharge pipe 16 and then into the mixing tank 1. Start the motor 18 to drive the rotating shaft 5 to rotate. The stirring rods 6 on both sides of the rotating shaft 5 fully mix the raw material in the tank. During the mixing, as the rotating shaft 5 rotates, the first upper scraper 71, the second upper scraper 72, the first lower scraper 73, the second lower scraper 74, the first vertical scraper 9, and the second vertical scraper 10 of the wall scraping mechanism 7 rotate together to scrape off the raw material adhering to the inner wall of the mixing tank 1, ensuring uniform mixing and preventing the accumulation of raw material from affecting the mixing ratio and mixing effect. After the mixing is completed, the mixed sealing grout material is discharged from the second discharge pipe 21 for operation. When it is necessary to clean the inside of the mixing tank 1, the water is delivered through the anti-winding rotating pipe 20. Water is injected into the connecting groove 81 through the connector 19. Since the bottom of the connecting groove 81 is fixedly connected to the top of the connecting hole 82, the cleaning water flows from the connecting groove 81 into the connecting hole 82. The connecting hole 82 is fixedly connected to the water injection grooves 83 respectively opened inside the first upper scraper 71 and the second upper scraper 72. Therefore, the cleaning water further flows into the water injection grooves 83. As the water pressure in the water injection grooves 83 increases, the water pressure overcomes the elastic force of the spring 810 and pushes the connecting block 87 connected to the moving rod 88 to slide on the inner wall of the housing 85, thereby opening the anti-clogging cover 86. The cleaning water in the water injection grooves 83 flows out through the water outlet 84 fixedly connected to the water injection grooves 83 to clean the inside of the mixing tank 1. When the cleaning is completed, the supply of cleaning water is stopped, the water pressure in the water injection grooves 83 decreases, the spring 810 returns to its elastic deformation, pulls the moving rod 88 and the connecting block 87, and resets the anti-clogging cover 86 to prevent debris from entering the water outlet 84 and causing blockage, thus preparing for the next cleaning.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
