[0001] The utility model relates to the technical field of aggregate detection equipment, in particular to an aggregate stone powder content detection device. Background Art

[0002] During the aggregate production line, the stone is hammered and struck repeatedly, which will produce some stone dust during the multiple impact crushing. If there is excessive crushing during production, more stone dust will be produced. The stone dust content is very sensitive to the performance of the concrete mix and must be tested in time.

[0003] The current method for testing aggregate stone dust content involves drying the aggregate, then washing it through a 0.16mm sieve. After washing, the sample on the 0.16mm sieve is then dried. The stone dust is removed by washing. This method requires two drying steps, 20 hours to complete, and two testers to operate, resulting in high costs and low efficiency.

[0004] Currently, there is no instrument specifically for detecting aggregate stone powder on the market, so an aggregate stone powder content detection device is proposed. Utility Model Content

[0025] The base 1 is hollow and has a transverse sliding groove 11 on the top surface of the base 1;

[0026] The box body 3 is arranged on the base 1;

[0027] The clamping assembly 2 is arranged on the upper part of the base 1 and includes a first motor 21, a reciprocating screw rod 22, a first clamping block 23 and a second clamping block 24. The first motor 21 is arranged on the side wall of the base 1. The output shaft of the first motor 21 passes through the side wall of the base 1 and is connected to the reciprocating screw rod 22. The reciprocating screw rod 22 is rotatably arranged in the base 1. The first clamping block 23 and the second clamping block 24 are respectively screwed to the left and right parts of the reciprocating screw rod 22 through threaded sleeves 25. The tops of the first clamping block 23 and the second clamping block 24 pass through the horizontal sliding groove 11 and clamp the left and right walls of the box body 3 respectively.

[0028] The test sieve 5 is arranged on the top of the box 3; a sieve cover 51 is provided on the test sieve 5; and a sieve fixing frame 52 is also provided outside the test sieve 5;

[0029] The first chamber 7 is provided in the box body 3 and is located directly below the test sieve 5. A second motor 71 is provided in the first chamber 7. A fan 72 is connected to the output shaft of the second motor 71 to form a negative pressure environment.

[0030] The second chamber 8 is provided at the bottom of the box body 3; a grid 81 is provided in the middle of the second chamber 8, and multiple screens 82 are provided on the grid 81; a third motor 83 is provided at the bottom, and a driving hammer 84 is connected to the output shaft of the third motor 83 to achieve vibration of the grid 81;

[0031] A vacuum cleaner 6 is provided in the housing 3 and is connected to the first chamber 7 via a first pipe 61 and to the second chamber 8 via a second pipe 62;

[0032] The dust collecting cylinder 4 is arranged on the side wall of the box body 3 and is connected to the top of the second chamber 8 through the third pipe 41 passing through the side wall of the box body 3 .

[0033] When using the device, first weigh the sample mass as A1, put the sample into the test sieve 5, cover the sieve cover 51, and use the sieve fixing frame 52 to screw down the sieve cover 51 to fix the test sieve 5, start the second motor 71 to apply negative pressure evenly, connect the suction port to the suction nozzle under the test sieve 5, connect the suction nozzle to the vacuum cleaner 6, and control the negative pressure to achieve stone powder separation; while performing negative pressure screening, start the first motor 21 of the clamping assembly 2, and the output shaft of the first motor 21 drives the reciprocating screw rod 22 to rotate. Since the first clamping block 23 and the second clamping block 24 are screwed to the reciprocating screw rod 22 through the threaded sleeve 25, the first clamping block 23 and the second clamping block 24 respectively clamp the box body 3 to generate reciprocating motion, driving the entire box body 3 to vibrate, thereby realizing the screening of the test sieve 5, and the different sieves on the test sieve 5 are weighed by an electronic balance, and the mass on the 5mm sieve is A4, the mass on the 2.5mm sieve is A5, the mass on the 1.25mm sieve is A6, the mass on the 0.63mm sieve is A7, and the mass on the 0.315mm sieve is A8. The vacuum cleaner 6 sucks the stone powder and transfers it to the multiple screens 82 for 0.08mm particle separation. The third motor 83 is started, driving the driving hammer 84 to rotate and vibrate the grid 81, thereby driving the vibration of the multiple screens 82 to separate the 0.08mm diameter upper and lower sieves. After the experiment is completed, the upper sieve mass is taken out and weighed on an electronic balance as A2, and the lower sieve mass is A3. During the entire process, the remaining dust-laden gas enters the dust collection tube 4 for storage and subsequent processing. After the results are obtained, the subsequent calculation is completed to complete the stone powder content grading test:

[0034] Stone powder content = (A2+A3) / A1*100;

[0035] Mud content = A3 / A1*100;

[0036] The gradation test results (residue on each sieve) are:

[0037] 5mm sieve residue = A4 / A1*100;

[0038] 2.5mm sieve residue = A5 / A1*100;

[0039] 1.25mm sieve residue = A6 / A1*100;
