[0002] Premixed mortar refers to various mortar mixtures produced by specialized manufacturers and used in construction projects. It is a new type of building material developed in my country in recent years. Premixed mortar is in powder form, which is convenient for later transportation and use. In the detection of premixed mortar, water absorption rate is one of the important indicators for detecting the quality of premixed mortar.

DETAILED DESCRIPTION

[0027] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0028] Please refer to Figures 1 to 6 As shown, a sand powder water absorption rate detection device of the utility model comprises a frame 8, a lifting mechanism 1, a transparent container 4, a quantitative watering mechanism 7 and an excess water removal mechanism 3, wherein the lifting mechanism 1 is arranged inside the frame 8, the transparent container 4 is movably connected to the lifting mechanism 1, the excess water removal mechanism 3 is arranged on the upper part of the transparent container 4, and the quantitative watering mechanism 7 is arranged on the upper part of the frame 8;

[0029] The excess water removal mechanism 3 includes a weighing seat 302, a connecting column 307, a collar 306 and a plurality of water absorbing components. The weighing seat 302 and the collar 306 are both sleeved on the upper part of the transparent container 4. The collar 306 is connected to the weighing seat 302 through a plurality of connecting columns 307. A plurality of groups of water absorbing components are arranged around the upper part of the collar 306.

[0030] The water absorbing component includes a rotating frame 303, a first rotating driving member 301, a bracket 308, a mounting shaft 305 and a water absorbing member 304. The lower portion of the rotating frame 303 is connected to the upper portion of the sleeve ring 306. One side of the bracket 308 is rotatably connected to the upper portion of the rotating frame 303 via a rotating shaft. The mounting shaft 305 is provided on the other side of the bracket 308. The outer surface of the mounting shaft 305 is wound with the water absorbing member 304. The first rotating driving member 301 is drivingly connected to the rotating shaft.

[0031] The working principle of the utility model is as follows: during the actual sand powder detection process, when it is necessary to detect the water absorption rate of the sand powder, a certain amount of sand powder can be put into the transparent container 4, and then the lifting mechanism 1 is operated to make the lifting mechanism 1 drive the transparent container 4 to rise to the position of the quantitative water sprinkling mechanism 7, and then the quantitative water sprinkling mechanism 7 is operated to make the quantitative water sprinkling mechanism 7 sprinkle water into the sand powder and be absorbed by the sand powder. The operator observes the water absorption state of the sand powder. When the sand powder is oversaturated with water, the water sprinkling is stopped immediately to obtain the value of the water sprinkling, and then the lifting mechanism 1 is operated to make the lifting mechanism 1 drive the transparent container 4 to descend, so that the transparent container 4 is separated from the quantitative water sprinkling mechanism 7. Before this, the weighing seat 302 weighs the initial weight of the ring 306 and the water absorption component on the ring 306 to obtain the weight of the water absorption component 304 without water absorption. When it is necessary to remove the saturated water in the sand powder, the first rotating drive member 301 can be operated, so that the first rotating drive drives the bracket 308 to rotate through the rotating shaft, so that the installation shaft 305 extends into the transparent container 4, and the bottom of the water absorbing member 304 contacts the sand powder, so that the excess water in the sand powder is absorbed by the water absorbing member 304. After the absorption is completed, the first rotating drive member 301 is operated to reset the installation shaft 305 and the water absorbing member 304 by the first rotating drive member 301, so that the water absorbing member 304 is separated from the transparent container 4, and then the weighing seat 302 is operated to make the weighing seat 302 obtain the weight of the excess water absorbed by the water absorbing member 304, and then the actual saturated water absorption of the sand powder is obtained by calculating the amount of water added to the sand powder minus the amount of water absorbed by the absorbing member, so that the water absorption rate can be calculated.

[0032] Furthermore, the lifting mechanism 1 includes a second rotating driving member 01, a screw rod 102, a slider 103 and a placement plate 104. A sliding groove matching the slider 103 is arranged inside the frame 8. One side of the slider 103 is slidably connected to the sliding groove. The placement plate 104 is arranged on the other side of the slider 103. The screw rod 102 is passed through the middle of the slider 103 and is rotatably connected to the frame 8. The second rotating driving member 01 is drivingly connected to the screw rod 102. A placement groove matching the transparent container 4 is arranged on the upper part of the placement plate 104, and the transparent container 4 is movably connected to the placement groove.

[0033] From the above description, it can be seen that when it is necessary to add water to the sand powder, the second rotating drive member 01 can be operated to drive the screw 102 to rotate, so that the slider 103 drives the placement plate 104 to rise, so that the transparent container 4 on the placement plate 104 is close to the quantitative watering mechanism 7, so that the quantitative watering mechanism 7 can better sprinkle water on the transparent container 4, and it is convenient for the subsequent stirring mechanism 2 to stir the sand powder, so that the transparent container 4 after stirring can be better separated from the stirring mechanism 2.

[0034] Furthermore, the quantitative watering mechanism 7 includes a quantitative water pumping member 704, a water diversion pipe 701, an annular pipe 702 and a nozzle 703. The annular pipe 702 is arranged above the placement plate 104 and connected to the upper part of the frame 8. A plurality of nozzles 703 are arranged around the lower part of the annular pipe 702. The upper part of the annular pipe 702 is connected to the quantitative water pumping member 704 through the water diversion pipe 701.

[0035] From the above description, it can be seen that when it is necessary to add water to the sand powder, the quantitative pumping component 704 can be operated to allow the quantitative pumping component 704 to introduce water into the annular tube 702 through the water pipe 701, and then spray it into the sand powder through the nozzle 703, so that the sand powder can absorb better and the amount of water added to the sand powder can be better obtained.

[0036] Furthermore, it also includes a stirring mechanism 2, and the stirring mechanism 2 is also arranged on the upper part of the frame 8. The stirring mechanism 2 includes a third rotating driving member 201, a stirring shaft 202 and a stirring paddle 203. The upper part of the stirring shaft 202 is rotatably connected to the frame 8, and the lower part of the stirring shaft 202 is provided with a stirring paddle 203. The third rotating driving member 201 is drivingly connected to the stirring shaft 202, and the stirring paddle 203 is arranged directly above the placement groove.

[0037] From the above description, it can be seen that when it is necessary to stir the sand powder during the water absorption process, the third rotating driving member 201 can be operated, so that the third rotating driving member 201 drives the stirring paddle 203 to stir the sand powder through the stirring shaft 202, so that the sand powder can absorb water better and more fully.

[0038] Furthermore, it also includes a protective cover 6, which is arranged on the outside of the placement plate 104 and connected to the frame 8.

[0039] From the above description, it can be seen that this is beneficial to prevent the sand powder from splashing outside the detection device during the stirring process.

[0040] Furthermore, a door panel 5 is included, and an inlet and outlet are arranged on a side of the protective cover 6 away from the slider 103 , and the door panel 5 is hinged at the inlet and outlet.

[0041] From the above description, it can be seen that it is beneficial for the transparent container 4 to better pass through the inlet and outlet to enter and exit the interior of the detection device, and the door panel 5 can better isolate the sand powder being detected.

[0042] Furthermore, it also includes a PLC controller, which is electrically connected to the lifting mechanism 1, the quantitative watering mechanism 7 and the excess water removal mechanism 3 respectively.

[0043] From the above description, it can be seen that it is beneficial to adjust the parameters of the water absorption detection device through the PLC controller, and it is more convenient for operators to operate the water absorption detection device.
