Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of manufactured sand detection, and particularly relates to a manufactured sand stone powder content automatic detection device. BACKGROUND

[0002] In recent years, the scale of civil engineering infrastructure construction is huge, and high-quality river sand resources are becoming scarce. Manufactured sand resources are rich, quality controllable, and low in cost, and have been widely used. With the enhancement of environmental awareness, the exploitable river sand resources are becoming less and less, and the manufactured sand will be more widely used. The adsorption performance of stone powder with a particle size less than 75 mu m in the manufactured sand is an important technical index for evaluating the performance of the manufactured sand. Currently, the related manufactured sand standards generally use the test method of manufactured sand methylene blue (MB) value.

[0003] According to the investigation, the Chinese invention patent discloses a manufactured sand methylene blue test automatic device and method (publication number: CN112595709A), which comprises a first sliding table, a stirring motor, a stirring shaft and stirring blades. One end of the first sliding table is fixedly connected to the upper end of the installation cabinet body. A connecting plate is vertically arranged on the sliding block of the first sliding table. The stirring motor is vertically fixed on the connecting plate, and the output shaft of the stirring motor penetrates through the connecting plate vertically downward. The output shaft of the stirring motor is fixed with the stirring shaft, and the tail end of the stirring shaft is fixed with the stirring blades. The stirring blades are located directly above the stirring barrel.

[0004] The above-mentioned patent can realize the automation of the whole process of detecting whether the stone powder content in the manufactured sand meets the standard under the action of the electrical control cabinet, reduce the labor intensity of the workers, avoid the error caused by manual operation, and adjust the proportions of coarse, medium and fine particles, i.e. perform gradation optimization, during the preparation of the manufactured sand. The stone powder mainly adheres to the fine sand during the screening process of the manufactured sand, and both of them occupy the "micropowder interval" of the fine aggregate. The mixed proportion is mainly used to make up for the defects of single sand source or meet the special engineering requirements. The stone powder detection is performed on the part of the sample in the graded manufactured sand. The preparation and detection devices of the manufactured sand are independent of each other, and a certain time is consumed from sampling to detection. If the detection result shows that the stone powder content does not meet the standard, the amount of fine sand cannot be adjusted in time. Although the device can automatically detect the stone powder content in the manufactured sand, it cannot monitor the manufactured sand in the preparation process in real time, and the sampling process consumes a long time.

[0005] Therefore, the present application provides a manufactured sand stone powder content automatic detection device to solve the above-mentioned problems. SUMMARY

[0020] (III) Beneficial Effects

[0021] 1. By setting up screening boxes and baffles, the proportions of coarse, medium, and fine sand entering the tank are precisely controlled. A mixing plate inside the tank is responsible for uniformly mixing the manufactured sand. A portion of the mixed product is sent into the testing cylinder for inspection. At this point, the stirring rod and dipping rod are driven sequentially to stir and test the manufactured sand in the testing cylinder, directly monitoring the quality of the manufactured sand during the gradation process. If the stone powder content in the manufactured sand is found to be substandard, the amount of fine sand added can be immediately controlled by adjusting the baffles, thereby significantly improving testing efficiency.

[0022] 2. The start and stop of the third cylinder are controlled by a metal ball. When the stirring rod moves directly above the detection cylinder, the third cylinder drives the first splined shaft in the linkage mechanism to move downward, causing the positioning block to embed into the positioning groove on the cylindrical block, thus connecting the first splined shaft and the second splined shaft. At this time, the rotating mounting rod can drive the stirring rod to rotate, stirring the manufactured sand in the detection cylinder. When the detection mechanism is not in operation, the positioning block separates from the positioning groove, which reduces the workload of the vibration motor and thus reduces energy consumption.

[0036] The detection cylinder 17 and the base 18 are fixedly connected in the tank body 1, a detection mechanism is arranged between the detection cylinder 17 and the partition plate 28, the detection mechanism comprises a gear ring 14, a driving wheel 31, a connecting ring 15, a stirring rod 25 and a dipping rod 16, the driving wheel 31 is engaged with the gear ring 14, the dipping rod 16 is fixedly connected with the connecting ring 15, and the stirring rod 25 is rotatably connected with the connecting ring 15; the manufactured sand in the detection cylinder 17 is stirred and detected by the stirring rod 25 and the dipping rod 16, so as to directly monitor the quality of the manufactured sand in the grading process; if it is found that the content of stone powder in the manufactured sand does not meet the standard, the amount of fine sand can be immediately controlled, and the detection efficiency is improved;

[0037] Specifically, in the preparation process of the manufactured sand, it is usually necessary to adjust the proportion of coarse, medium and fine particles, that is, to optimize the grading;

[0038] A mounting rod 10 is rotatably connected between the partition 28 and the top of the tank 1. A mixing plate 11 is fixedly connected to the mounting rod 10. A linkage mechanism is provided between the mounting rod 10 and the stirring rod 25. The linkage mechanism includes a first sleeve 37, a first splined shaft 44, a positioning block 38, a transmission belt 34, and two pulleys 33. The transmission belt 34 is connected between the two pulleys 33. The first splined shaft 44 slides coaxially with the first sleeve 37.

When the positioning block 38 is not completely aligned with the positioning groove, the downward-moving positioning block 38 cannot be fully inserted into the positioning groove. At this time, the fourth spring will be compressed. When the positioning block 38 rotates, the positioning block 38 gradually aligns completely with the positioning groove. At this time, the compressed fourth spring resets and pushes the positioning block 38 to be fully inserted into the mounting groove, thus realizing the connection between the first spline shaft 44 and the stirring rod 25.
