Description

Technical Field

[0001] This utility model is a device for detecting the mud content of building mortar, belonging to the field of mortar testing. Background Technology

[0002] Construction mortar, an indispensable material in building construction, is widely used in wall masonry, floor paving, and decorative finishing. Its quality directly affects the safety, durability, and stability of building projects. The mud content in mortar is one of the key indicators for measuring its quality. The presence of mud will significantly weaken the bond between cement and aggregate, reduce the strength of the mortar, and lead to problems such as wall cracking and floor hollowing. In severe cases, it may even threaten the safety of the building structure. Therefore, accurately detecting the mud content of construction mortar has become a core link in ensuring the quality of building projects.

[0003] Currently, the detection of mud content in building mortar mainly adopts the traditional water washing and screening method and the drying and weighing method. The water washing and screening method relies on manual stirring and rinsing of mortar samples in water, and separating sand and mud through a filter screen. This process is greatly affected by factors such as the operator's experience, stirring force, and rinsing time, and is prone to problems such as uneven stirring and mud residue, resulting in high error in the test results. The drying and weighing method requires transferring the sand and gravel to drying equipment after water washing, and then calculating the mud content by weighing. Not only is the operation process cumbersome and time-consuming, but the multiple transfers of samples are also prone to damage, affecting the accuracy of the test. In addition, most existing testing equipment is a split design, and the steps of water washing, filtration, and drying must be completed in different equipment, resulting in low automation and difficulty in meeting the needs of rapid testing of large numbers of samples in construction projects. At the same time, traditional testing equipment lacks closed-loop control of the testing process, and the disposal of sand and mud after testing is inconvenient, with drawbacks such as large amount of manual cleaning workload and high environmental pollution risk. Therefore, it is necessary to design a device for detecting mud content in building mortar. Utility Model Content

Detailed Implementation

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] Please see Figures 1 to 9 This utility model provides a technical solution: a device for detecting the mud content of building mortar, including a base 1, an electronic scale 9 disposed at the center of the top of the base 1, a detection cylinder 5 mounted on the top of the electronic scale 9, a top cover 7 mounted on the top of the detection cylinder 5, and an air hole 701 opened on the top cover 7, a drive assembly 8 disposed at the center of the top of the top cover 7, and a water spraying assembly 6 mounted on the top cover 7 outside the drive assembly 8, a filter assembly disposed in the lower half of the inside of the detection cylinder 5, and a heating wire 20 disposed on the inner wall of the detection cylinder 5 above the filter assembly. A mixing assembly is installed inside the detection cylinder 5 above the component, and the top of the mixing assembly is connected to the drive assembly 8. Installation chambers 101 are opened on both sides of the base 1, and a water purification pump 3 and a mud pump 10 are respectively installed in the two installation chambers 101. A control panel 2 is installed at one end of the base 1. During the detection process, the electronic scale 9 weighs the detection cylinder 5 three times. The first time, the weight of the detection cylinder 5 itself is weighed. The second time, the weight of the detection cylinder 5 after adding mortar is weighed. The third time, the weight of the sand and gravel after desliming and drying is weighed. The control panel 2 can combine the three weighing data to accurately calculate the mud content of the mortar. For example, the input end of the water purifier pump 3 is connected to the inlet pipe 301, and the output end of the water purifier pump 3 is equipped with the outlet pipe 302. The outlet pipe 302 is connected to the input end of the sprinkler assembly 6. The input end of the mud pump 10 is connected to the bottom end of one side of the detection cylinder 5 through the mud conduit 1001, and the output end of the mud pump 10 is connected to the mud discharge pipe 1002. The automated operation of the water purifier pump 3 and the mud pump 10 realizes the automatic transmission of water and mud without the need for manual handling or dumping of liquids.

[0018] For example, the bottom of the inside of the detection cylinder 5 is a frustum-shaped design with a thicker top and a thinner bottom. A sand discharge pump 501 is fixed at the bottom of the detection cylinder 5 near the control panel 2. A downward-sloping channel is provided between the sand discharge pump 501 and the bottom of the inside of the detection cylinder 5. A sand inlet pump 502 is installed at the top of the end of the detection cylinder 5 away from the control panel 2. An annular limiting seat 4 with an inner diameter matching the outer diameter of the detection cylinder 5 is provided at the top of the base 1 on the outside of the electronic scale 9. Openings 401 are provided on both sides of the annular limiting seat 4 and at the end near the sand discharge pump 501. The frustum-shaped design with a thicker top and a thinner bottom inside the detection cylinder 5, together with the sand discharge pump 501 and the inclined channel at the bottom of the detection cylinder 5, allows sand and gravel to quickly converge and be discharged under the action of gravity and pump suction. During the sand discharge stage, sand and gravel can be quickly extracted by the sand discharge pump 501 through the channel.

[0019] Please see Figure 1 and Figure 7 The sprinkler assembly 6 includes a water guide ring 601, a limiting sleeve 602, a distribution branch pipe 603, a corrugated pipe 604, a hinge plate 605, and a nozzle 606. The water guide ring 601 is fixed to the top of the top cover 7 by the limiting sleeve 602, and the water guide ring 601 coincides with the central axis of the detection cylinder 5. One side of the water guide ring 601 is connected to the outlet pipe 302 of the water purifier pump 3, and four distribution branch pipes 603 are evenly spaced at the bottom of the water guide ring 601. The bottom of the distribution branch pipes 603 penetrates the top cover 7, and hinge plates 605 are fixed on both sides of the distribution branch pipes 603 below the top cover 7. Below the distribution branch pipe 603, a nozzle 606 is connected via a corrugated pipe 604, and the nozzle 606 is hinged to the hinge plate 605. In the water spraying assembly 6, four distribution branch pipes 603, which are equally spaced at the bottom of the water guide ring 601, can disperse the water input from the water pump 3 to different areas of the detection cylinder 5, and then spray it out through the nozzle 606, ensuring that the mortar can be evenly contacted by the water flow during the mixing and dissolving stage. The nozzle 606 is connected to the distribution branch pipe 603 via the corrugated pipe 604 and is hinged to the hinge plate 605, so that the nozzle 606 can flexibly adjust the angle.

[0020] Please see Figure 1 and Figure 3, the driving assembly 8 comprises a driving motor 11, a mounting frame 12, a main bevel gear 13, a first auxiliary bevel gear 14 and a second auxiliary bevel gear 15. The mounting frame 12 is designed in a ""匚"" shape, and the end portions of two transverse plates of the mounting frame 12 are integrally connected with limit rings. The driving motor 11 is fixed on one side of a vertical plate of the mounting frame 12 away from the center of a top cover 7, and the main bevel gear 13 is mounted on one side of the vertical plate of the mounting frame 12 close to the center of the top cover 7. The central axes of the two limit rings both coincide with the central axis of a detection cylinder 5. The bottom of the upper limit ring is rotatably connected with the first auxiliary bevel gear 14 meshed with the main bevel gear 13, and the top of the lower limit ring is rotatably connected with the second auxiliary bevel gear 15 meshed with the main bevel gear 13. The main bevel gear 13 drives the first auxiliary bevel gear 14 and the second auxiliary bevel gear 15 simultaneously. The bottom of the first auxiliary bevel gear 14 is fixedly connected with the top of an inner tube 18 to drive the inner tube 18 to rotate clockwise; the top of the second auxiliary bevel gear 15 is fixedly connected with the bottom of an outer tube 16 to drive the outer tube 16 to rotate counterclockwise, so that reverse rotation of the inner tube 18 and the outer tube 16 is realized. The mounting frame 12 is aligned with the central axis of the detection cylinder 5 through the limit rings, which ensures the concentricity of the driving assembly 8 and the stirring assembly and avoids equipment shaking and wear caused by eccentricity.

[0021] Please refer to Figures 3-5 , the stirring assembly comprises an outer tube 16, an inner tube 18, an anti-dropping plate 1801, a stirring frame 19, a silica gel scraper 1901, inserting slots 1902 and an auger 23. The inner tube 18 penetrates through the interior of the outer tube 16, and the auger 23 is fixed at the lower half section outside the outer tube 16. The outer diameter of the inner tube 18 matches the inner diameter of the outer tube 16, the bottom of the inner tube 18 is rotatably connected with the center of the top of a filtering assembly, the bottom of the inner tube 18 is connected with the stirring frame 19 in a ""凵"" shape, and inserting slots 1902 are formed in both sides and the bottom of the stirring frame 19. The silica gel scraper 1901 is inserted into the inserting slots 1902, and three sides of the silica gel scraper 1901 are respectively attached to the inner wall of the detection cylinder 5 and the top of the filtering assembly. The top of the outer tube 16 penetrates the top cover 7 and is fixedly connected with the second auxiliary bevel gear 15, and the top of the inner tube 18 penetrates the second auxiliary bevel gear 15 and is fixedly connected with the first auxiliary bevel gear 14. The first auxiliary bevel gear 14 drives the inner tube 18 to rotate clockwise, the ""凵""-shaped stirring frame 19 at the bottom of the inner tube 18 rotates accordingly, and the silica gel scraper 1901 fixed to the stirring frame 19 through the inserting slots 1902 scrapes the inner wall of the detection cylinder 5 and the top of the filtering assembly, so as to prevent mortar from adhering. The second auxiliary bevel gear 15 drives the outer tube 16 to rotate counterclockwise, the auger 23 on the outer side of the outer tube 16 rotates synchronously to form upward water flow disturbance, which cooperates with the stirring effect of the stirring frame 19 to enhance the mixing effect of mortar and water.

[0022] Please refer to Figure 4 and Figure 8The filter assembly includes a rotating disk 21, a base plate 22, a servo motor 25, and a filter screen 26. A sealed container is located at the center of the bottom of the base plate 22, and the servo motor 25 is installed inside the sealed container. The output end of the servo motor 25 is connected to the center of the rotating disk 21. The base plate 22 on both sides of the servo motor 25 has symmetrically opened material discharge ports 2201 with a 45° fan-shaped design. The rotating disk 21 has four through slots 2101 at equal angles, and the through slots 2101 have a 40° fan-shaped design, with two slots alternating. A filter screen 26 is installed in the through channel 2101. The servo motor 25 drives the rotating disk 21 to switch between three states: closed, filtered, and fully open. In the closed state, sand and gravel are prevented from leaking when water is added, ensuring the mixing and dissolving effect. In the filtered state, the filter screen 26 is aligned with the discharge port 2201 to separate sand and gravel from mud. In the fully open state, the through channel 2101 without the filter screen 26 is aligned with the discharge port 2201, and sand and gravel can be discharged quickly. The fully automated state switching reduces manual intervention and is more efficient than the traditional manual operation of the testing process.

[0023] Please see Figure 4 and Figure 6 The outer tube 16 above the auger 23 has a guide groove 1601 on its outer wall, and the guide groove 1601 is an upwardly sloping elliptical design. The outer tube 16 is fitted with a movable sleeve 17 whose inner diameter matches its outer diameter. The inner side wall of the movable sleeve 17 is provided with a limiting protrusion 1701 that matches the guide groove 1601. The outer side wall of the movable sleeve 17 is hinged with four tie rods 24 at equal intervals, and the other end of the tie rods 24 is hinged to the side wall of the nozzle 606. When the outer tube 16 rotates, the circular motion is converted into the up-and-down reciprocating motion of the movable sleeve 17 through the cooperation of the guide groove 1601 and the limiting protrusion 1701. The movable sleeve 17 drives the nozzle 606 to swing around the hinge point through the tie rods 24, so that the nozzle 606 can achieve multi-angle coverage during water spraying, thereby enhancing the flushing effect of the water flow on the mortar.

[0024] Specific implementation method: When in use, the detection cylinder 5 is placed on the electronic scale 9 on the base 1, and the annular limit seat 4 is used for auxiliary positioning. The electronic scale 9 weighs the detection cylinder 5 for the first time to obtain its own weight. Subsequently, the sand pump 502 injects the sample from the top of the detection cylinder 5. After completion, the electronic scale 9 weighs the mortar a second time to obtain the mortar weight. At this time, the rotating disk 21 of the filter assembly is in a closed state to prevent sample leakage. The water pump 3 draws water through the inlet pipe 301 and delivers it to the water spraying assembly 6 through the outlet pipe 302. The water guide ring 601 disperses the water into four distribution branch pipes 603, and finally sprays it into the detection cylinder 5 through the nozzle 606. At the same time, the drive motor 11 in the drive assembly 8 drives the main bevel gear 13 to rotate, meshing the first set of bevel gears 14 and the second set of bevel gears 15, causing the inner tube 18 and the outer tube 16 to rotate in opposite directions. The inner tube 18 drives the mixing frame 19 to stir the mortar. The silicone scraper 1901 scrapes the cylinder wall to prevent adhesion. The outer tube 16 drives the auger 23 to lift the water flow disturbance, and the heating wire 20 accelerates the dissolution of the mud. In addition, when the outer tube 16 rotates, it interacts with the guide groove 1601 and the limiting protrusion 17. The coordination of 01 drives the movable sleeve 17 and pull rod 24 to make the nozzle 606 swing, spraying water at multiple angles to enhance the dissolving effect. The servo motor 25 drives the rotating disk 21 to switch to the filtration state. The through groove 2101 with filter screen 26 is aligned with the material outlet 2201 of the bottom plate 22. Mud and fine particles enter below through the filter screen 26, while sand and gravel remain above the filter screen 26. The mud pump 10 discharges the mud through the mud conduit 1001 and the mud discharge pipe 1002. After filtration, the heating wire 20 dries the sand and gravel. The stirring component runs at low speed to assist in drying. After drying, the electronic scale 9 weighs for the third time. The control panel 2 combines the three weighing data to accurately calculate the mud content of the mortar. The servo motor 25 drives the rotating disk 21 to switch to the full-pass state. The through groove 2101 without filter screen 26 is aligned with the material outlet 2201. The sand discharge pump 501 uses the inclined channel at the bottom of the detection cylinder 5 to quickly discharge the sand and gravel.
