Description

Technical Field

[0001] This application relates to the field of sand mud content detection technology, specifically a device for detecting the mud content of concrete sand. Background Technology

[0002] In construction engineering, concrete is one of the most commonly used building materials, and its performance directly affects the structural safety and service life of buildings. Sand, as the main component of concrete, plays a crucial role in the performance of concrete. The mud content in sand is one of the key factors affecting the strength, durability and workability of concrete. Therefore, accurate and rapid detection of the mud content of sand used in concrete is of great significance for ensuring project quality.

[0003] An existing patent (publication number: CN212646381U) discloses a device for detecting the mud content of concrete sand. It includes a silo with four walls made of 0.5-1mm mesh screens. An outer shell surrounds the silo, with a water outlet channel connecting the outer shell to the silo walls. A circular hole is located in the center of the silo's bottom, through which a rotating shaft passes. The shaft has stirring blades, and a waterproof plug is installed at the connection between the shaft and the bottom of the silo. The shaft is connected to the central shaft of a motor located at the lower edge of the silo's bottom. A weight sensor is located at the bottom of the silo and connected to a display screen above the outer shell. A heating rod is also located at the bottom of the silo and connected to a power source. The motor is mounted on a partition, forming a mud-water chamber between the partition and the outer shell. A water outlet is located at the lower edge of the mud-water chamber. This device is used to detect the mud content of crushed stone to meet the strength requirements for pipe pile manufacturing.

[0004] However, in the existing technology, the main steps of the method for detecting the mud content in sand in concrete include: sampling, mixing and separation, filtration and drying. In the filtration step, because the filter screen in the existing equipment is not easy to replace, when the screen is severely worn or the aperture deviation is large, it will cause particles to be missed or mis-screened. Furthermore, since the diameter of sand particles on the market is different, the filter screen cannot be replaced, so it is not possible to separate sand and mud of different particle sizes. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a device for detecting the mud content of concrete sand. This device has the advantages of being able to replace severely worn or large-diameter filters, and being able to separate sand and mud of different particle sizes. It solves the problems in existing technologies where filters are inconvenient to replace, and when the screen is severely worn or has large-diameter deviations, particles may be missed or mis-screened, and different particle sizes of sand and mud cannot be separated.

[0006] To achieve the above objectives, this application provides the following technical solution: a device for detecting the mud content of concrete sand, comprising a sand washing tank, a limiting ring fixedly connected to the inner wall of the sand washing tank, a filter screen provided on the upper surface of the limiting ring, connecting rods arranged at equal intervals fixedly connected to the upper surface of the filter screen, mounting grooves arranged at equal intervals opened on the upper surface of the sand washing tank, a mounting block slidably connected to the inner wall of each mounting groove, a limiting pin fixedly connected to the bottom surface of each mounting block, the outer surface of each limiting pin slidably connected to the inner wall of the corresponding connecting rod, and a fixing bolt installed between each mounting block and the corresponding mounting groove.

[0007] The above-described solution involves installing a limiting ring on the inner wall of the sand washing tank, placing the filter screen above the limiting ring, and creating an installation groove on the inner wall of the sand washing tank. Moving the filter screen aligns the connecting rod with the corresponding installation groove, and then moving the installation block allows the corresponding limiting pin to connect with the connecting rod and the installation block to the corresponding installation groove. The installation block is then locked with fixing bolts, thus installing the filter screen. Conversely, removing the corresponding installation block allows for the removal of the filter screen. This device facilitates the replacement of severely worn or poorly sized filter screens, preventing missed or incorrect screening. Furthermore, by replacing filter screens with different aperture sizes, it can separate sand and mud of different particle sizes, improving its applicability.

[0008] Furthermore, a mounting base plate is provided below the sand washing tank, and a weighing module is fixedly installed on the upper surface of the mounting base plate. The sand washing tank is placed on the upper surface of the weighing module, and a guide block is fixedly connected to the inner bottom wall of the sand washing tank.

[0009] The above scheme involves placing the mounting base plate below the sand washing tank and placing the weighing module on the upper surface of the mounting base plate. The bottom surface of the sand washing tank is in contact with the weighing platform of the weighing module. The weighing module can weigh the overall weight of the sand washing tank, the weight of the sand-mud mixture, and the weight of the dried sand after filtering out impurities such as mud. A guide block is installed on the inner bottom wall of the sand washing tank. The guide block can guide the filtered mud-water mixture to one side of the sand washing tank for easy drainage.

[0010] Furthermore, an ultrasonic generator is fixedly installed on the inner wall of the sand washing barrel, a water outlet pipe is fixedly connected to the outer surface of the sand washing barrel, and a drying wire is fixedly installed on the inner wall of the sand washing barrel.

[0011] The above solution involves installing an ultrasonic generator on the inner wall of the sand washing tank. This allows the generator to emit ultrasonic waves that vibrate impurities in the liquid, improving the filtration effect. A water outlet pipe is installed on the outer surface of the sand washing tank, facilitating the discharge of the mud-water mixture. A heating wire is installed on the inner wall of the sand washing tank, heating the tank to dry the remaining sand on the filter screen. After drying, the sand is weighed using a weighing module.

[0012] Furthermore, a sealing cover is provided above the sand washing tank, and handles arranged at equal intervals are fixedly connected to the outer surface of the sealing cover, and a motor is fixedly connected to the upper surface of the sealing cover.

[0013] The above solution involves placing the sealing cover above the sand washing tank, installing a handle on the surface of the sealing cover for a fixed connection, and using the handle to facilitate lifting and moving the sealing cover, making it convenient for operators to operate. The motor is fixed to the upper surface of the sealing cover, and the motor's output shaft passes through the sealing cover to achieve motor installation.

[0014] Furthermore, the output shaft of the motor is fixedly connected to a gear one, and two gear two mesh with the outer surface of the gear one.

[0015] The above scheme involves mounting gear one on the output shaft of the motor as a fixed connection, with the motor enabling gear one to rotate. Gear two is positioned on the side of gear one, with two gears of gear two connected to gear one. The rotation of gear one allows gear two to rotate synchronously.

[0016] Furthermore, a round rod is fixedly connected to the inner wall of each gear II, the outer surface of each round rod is rotatably connected to the inner wall of the sealing cover, and a stirring assembly is fixedly connected to the bottom end of each round rod.

[0017] The above scheme involves installing a round rod on the inner wall of the corresponding gear two, forming a fixed connection. The rotation of gear two allows the round rod to rotate. The outer surface of the round rod is connected to the inner wall of the sealing cover, forming a rotatable connection to limit the movement of the round rod. The stirring assembly is installed at the bottom of the round rod, forming a fixed connection. The rotation of the round rod allows the stirring assembly to rotate, stirring the sand, mud, and water inside the sand washing tank. In conjunction with the ultrasonic generator, the stirring and separation efficiency is improved.

[0018] Furthermore, a retainer is rotatably connected to the bottom surface of the gear one, and the outer surface of each of the round rods is rotatably connected to the inner wall of the retainer.

[0019] The above scheme involves mounting the cage on the bottom surface of gear one, setting it as a rotatable connection. When gear one rotates, the cage will not rotate. Furthermore, the inner wall of the cage is connected to the surface of the round rod, also setting it as a rotatable connection, thereby achieving a limiting effect on the middle section of the round rod and improving the stability of the round rod's rotation.

[0020] Furthermore, a fixing ring is fixedly connected to the outer surface of the sand washing tank, and pins arranged at equal intervals are fixedly connected to the upper surface of the fixing ring. The outer surface of each pin is slidably connected to the inner wall of the sealing cover.

[0021] The above solution involves installing the fixing ring on the outer surface of the sand washing tank as a fixed connection, achieving the positioning and installation effect of the fixing ring. The pin is fixed on the upper surface of the fixing ring and connected to the sealing cover. The pin can limit the sealing cover, ensuring that the motor can work stably.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This concrete sand mud content testing device comprises a limiting ring, connecting rod, mounting block, and limiting pin. By removing the fixing bolts, the mounting block can be disassembled from the mounting groove, thereby allowing the limiting pin to be removed and releasing the limiting of the connecting rod. At this point, the filter screen can be removed from the surface of the limiting ring for easy replacement. This facilitates the replacement of filters with severe wear or large pore size deviations. Furthermore, by replacing filters with different pore sizes, different particle sizes of sand and mud can be separated. A motor drives gear one to rotate, which in turn drives two gears two to rotate a circular rod, thereby rotating the mixing component. In conjunction with an ultrasonic generator, the efficiency of separating sand particles from mud and other impurities is improved. Attached Figure Description

Each mounting block 6 is connected to the corresponding mounting groove 5 with a fixing bolt 8.

[0033] Please see Figure 1 , Figure 2 and Figure 3 A base plate 9 is provided below the sand washing tank 1. A weighing module 10 is fixedly installed on the upper surface of the base plate 9. The sand washing tank 1 is placed on the upper surface of the weighing module 10. A guide block 11 is fixedly connected to the inner bottom wall of the sand washing tank 1. The base plate 9 is placed below the sand washing tank 1, and the weighing module 10 is placed on the upper surface of the base plate 9. The bottom surface of the sand washing tank 1 is in contact with the weighing platform of the weighing module 10. The weighing module 10 can weigh the weight of the entire sand washing tank 1 device, the weight of the sand-mud mixture, and the weight of the dried sand after filtering out mud and other impurities. The guide block 11 is installed on the inner bottom wall of the sand washing tank 1. The guide block 11 can guide the filtered mud-water mixture to one side of the sand washing tank 1 for easy drainage.

[0034] Please see Figure 3 , Figure 4 and Figure 5An ultrasonic generator 12 is fixedly installed on the inner wall of the sand washing tank 1. A water outlet pipe 13 is fixedly connected to the outer surface of the sand washing tank 1. A drying wire 14 is fixedly installed on the inner wall of the sand washing tank 1. The ultrasonic generator 12 is installed on the inner wall of the sand washing tank 1 to realize the installation of the ultrasonic generator 12. The ultrasonic generator 12 can emit ultrasonic waves to vibrate the impurities in the liquid and improve the filtration effect. The water outlet pipe 13 is installed on the outer surface of the sand washing tank 1 to facilitate the discharge of the mud-water mixture. The drying wire 14 is installed on the inner wall of the sand washing tank 1. The drying wire 14 is a heating wire. By heating the sand washing tank 1, the remaining sand on the filter screen 3 can be dried. After drying, it is weighed by the weighing module 10.

[0035] Please see Figure 2 , Figure 3 and Figure 4 A sealing cover 15 is provided above the sand washing tank 1. Handles 16 arranged at equal intervals are fixedly connected to the outer surface of the sealing cover 15. A motor 17 is fixedly connected to the upper surface of the sealing cover 15. The sealing cover 15 is placed above the sand washing tank 1, and the handles 16 are installed on the surface of the sealing cover 15 for fixed connection. The handles 16 facilitate the lifting and moving of the sealing cover 15, making it convenient for operators to operate. The motor 17 is fixed to the upper surface of the sealing cover 15, and the output shaft of the motor 17 passes through the sealing cover 15 to realize the installation of the motor 17.

[0036] Please see Figure 4 The output shaft of motor 17 is fixedly connected to gear 18. Two gears 19 mesh on the outer surface of gear 18. Gear 18 is mounted on the output shaft of motor 17 and fixedly connected. Motor 17 enables gear 18 to rotate. Gears 19 are set on the side of gear 18. Two gears 19 are set and connected to gear 18. The rotation of gear 18 enables gears 19 to rotate, and gears 19 can rotate synchronously.

[0037] Please see Figure 4 Each gear 19 has a fixedly connected round rod 20 to its inner wall. The outer surface of each round rod 20 is rotatably connected to the inner wall of the sealing cover 15. The bottom end of each round rod 20 is fixedly connected to a stirring assembly 21. The round rod 20 is installed on the inner wall of the corresponding gear 19, which is a fixed connection. The rotation of the gear 19 allows the round rod 20 to rotate. The outer surface of the round rod 20 is connected to the inner wall of the sealing cover 15, which is a rotatable connection, thus limiting the position of the round rod 20. The stirring assembly 21 is installed on the bottom end of the round rod 20, which is a fixed connection. The rotation of the round rod 20 allows the stirring assembly 21 to rotate, thus stirring the sand, mud and water inside the sand washing tank 1. In conjunction with the ultrasonic generator 12, the stirring and separation efficiency is improved.

[0038] Please see Figure 4 A retainer 22 is rotatably connected to the bottom surface of gear 18. The outer surface of each round rod 20 is rotatably connected to the inner wall of the retainer 22. The retainer 22 is installed on the bottom surface of gear 18 and configured as a rotatable connection. When gear 18 rotates, the retainer 22 will not rotate. The inner wall of the retainer 22 is connected to the surface of the round rod 20 and configured as a rotatable connection. This achieves the effect of limiting the middle section of the round rod 20 and improves the stability of the rotation of the round rod 20.

[0039] Please see Figure 2 and Figure 4 A fixing ring 23 is fixedly connected to the outer surface of the sand washing tank 1. A pin 24 arranged at equal intervals is fixedly connected to the upper surface of the fixing ring 23. The outer surface of each pin 24 is slidably connected to the inner wall of the sealing cover 15. The fixing ring 23 is installed on the outer surface of the sand washing tank 1 to achieve a fixed connection and realize the positioning and installation effect of the fixing ring 23. The pin 24 is fixed to the upper surface of the fixing ring 23 and connected to the sealing cover 15. The pin 24 can limit the sealing cover 15 to ensure that the motor 17 can work stably.

[0040] This embodiment of a concrete sand mud content detection device includes components such as a limiting ring 2, a connecting rod 4, a mounting block 6, and a limiting pin 7. By removing the fixing bolts 8, the mounting block 6 can be disassembled from the mounting groove 5, thereby allowing the limiting pin 7 to be disassembled and releasing the limiting of the connecting rod 4. At this time, the filter screen 3 can be removed from the surface of the limiting ring 2, facilitating the replacement of the filter screen 3. This allows for the replacement of filter screens 3 that are severely worn or have large pore size deviations. Furthermore, by replacing the filter screen 3 with one of different pore sizes, different particle sizes of sand and mud can be separated. The motor 17 drives the gear 18 to rotate, which in turn drives the two gears 19 to rotate the round rod 20, thereby causing the mixing assembly 21 to rotate. In conjunction with the ultrasonic generator 12, the efficiency of separating sand particles from mud and other impurities is improved.

[0041] It should be noted that when gear 18 rotates, the two gears 19 can rotate synchronously in the same direction. However, the two stirring components 21 are set in opposite directions. Therefore, when the two gears 19 rotate in the same direction, the two stirring components 21 can generate opposite rotational forces, producing a turbulence effect.

[0042] The working principle of the above embodiments is as follows:

[0043] First, a certain amount of the sand-mud mixture is placed on the filter screen 3, and the weight displayed on the weighing module 10 is observed. Then, water is injected into the sand washing tank 1, with the injection level above the stirring assembly 21. Next, the movable sealing cover 15 is connected to the pin 24. Simultaneously, the ultrasonic generator 12 is started, and the motor 17 is activated, causing gear 18 to rotate, which in turn causes two gears 19 to rotate. Gears 19 drive two round rods 20 to rotate, which in turn drive the stirring assembly 21 to stir the mixture, separating the sand particles from the mud and other impurities. During the settling process, the mud and impurities settle through the filter screen 3, while the sand particles remain on the surface of the filter screen 3. The mixture is then separated by the guide block 11 and the water outlet pipe 13. The mixture of mud and water is drained, leaving only sand particles inside the sand washing tank 1. The sand particles are then dried by the drying wire 14. After drying, the sealing cover 15 and other components are removed, and the weight displayed on the weighing module 10 is observed again. The mud content is calculated. When the filter screen 3 needs to be replaced, the fixing bolt 8 is removed, allowing the mounting block 6 to be disassembled from the mounting groove 5. This causes the limit pin 7 to be disassembled, releasing the limit on the connecting rod 4. At this time, the filter screen 3 can be removed, facilitating its replacement. This allows for the replacement of filter screens 3 that are severely worn or have large pore size deviations, preventing missed screening or incorrect screening. At the same time, by replacing the filter screen 3 with different pore sizes, different particle sizes of sand and mud can be separated, improving the applicability of the device.
