[0002] In the field of concrete construction, the mud content of sand and gravel has a significant impact on the performance of concrete (especially strength and durability). High-performance concrete has more stringent requirements for the mud content of sand and gravel. Therefore, the accuracy of the determination result of the mud content in concrete sand and gravel has an important impact on the performance such as the strength of concrete. In the existing sand and gravel mud content detection devices, most of them require the mud and stones to be dried before detection, and the evaporation of water during the drying process is relatively difficult, which takes a long time and the process is relatively cumbersome.

Specific implementation manner

[0024] As Figures 1-6 shown, a sand and gravel mud content detection device includes a separation drum 1, a weighing device 2, an operating platform 3, a frame body 4, and a motor 5. The separation drum 1 and the weighing device 2 are respectively arranged on the frame body 4. The operating platform 3 is arranged on the side surface of the frame body 4. The motor 5 is installed in the frame body 4. The output shaft of the motor 5 penetrates through the surface of the frame body 4. The separation drum 1 is installed on the output shaft of the motor 5. The separation drum 1 includes an inner cylinder 11, an outer cylinder 12, and a cover 13. The inner cylinder 11 is arranged inside the outer cylinder 12. The cover 13 covers the outer cylinder 12. A channel for discharging water vapor is provided between the inner cylinder 11 and the outer cylinder 12 to discharge the water in the sediment by driving the separation drum 1 to rotate through the motor 5. Since a containing boss 111 is arranged inside the inner cylinder 11, the upper end surface of the containing boss 111 is in a concave shape. A filtering part 1111 is arranged on the edge of the concave surface of the containing boss 111. Multiple filter holes for filtering sand and gravel are provided on the surface of the filtering part 1111.

[0025] When detecting the mud content of sand and gravel, the sand and gravel to be detected can be placed in the concave surface at the upper end of the containing boss 111. Then, water is slowly poured into the concave surface at the upper end of the containing boss 111 by means of an external water pipe or manual water addition to dilute the soil in the sand and gravel. At the same time, the motor 5 is started, and the motor 5 drives the separation drum 1 to rotate through 51, so that the water in the concave surface at the upper end of the containing boss 111, together with the diluted slurry, is thrown by centrifugal force and sprayed out along the filter holes formed on the surface of the filtering part 1111. Although the gravel will also be thrown by centrifugal force, the diameter and volume of the gravel are relatively large and will be intercepted by the filtering part 1111. Subsequently, the above process is repeated many times until only gravel remains in the concave surface at the upper end of the containing boss 111. Then, the gravel is taken and placed on the weighing device 2 for weighing. Before the detection, the inner cylinder 11 can be removed, weighed by the weighing device 2, and the detected weight can be reset to zero. Then, the inner cylinder 11 is installed in the outer cylinder 12 for sand and gravel separation work. Subsequently, the weight of the separated gravel is calculated, and the ratio of the calculated weight to the weight of the original sand and gravel is obtained, so as to obtain the mud water content ratio. Subsequently, after drying the water in the mud by a dryer, the weight of the soil without water can be obtained, and the calculation of the weight ratio of gravel to mud can be completed.

[0026] Based on the above working principle, water can be continuously and slowly poured into the concave surface at the upper end of the containing boss 111 through an external water pipe to continuously dilute the soil in the sand and gravel and accelerate the stripping of the soil in the sand and gravel. In this operation mode, the cover 13 can be removed first, and the water pipe can be fixed by erecting a frame and attaching the water pipe. Aligning the water outlet of the water pipe with the concave surface at the upper end of the containing boss 111 can form continuous perfusion of water flow, reducing the time required to separate the soil.

[0027] Moreover, the inner side of the outer cylinder 12 is connected to the outer side surface of the inner cylinder 11 through a shielding piece 121. The shielding piece 121 is arranged with a smaller upper part and a larger lower part. When separating water from the inner cylinder 11, the shielding piece 121 can be used to shield it to prevent it from seeping into the connection end between the inner cylinder 11 and the outer cylinder 12.

[0028] The outer side surface of the containing boss 111 is in contact with the inner side surface of the inner cylinder 11, and the height of the lower end contour of the containing boss 111 is higher than the height of the connection between the inner cylinder 11 and the covering piece 121. A plurality of discharge ports 112 are provided on the surface of the inner cylinder 11, and the installation height of each discharge port 112 is at the same horizontal plane as the height of the lower edge of the containing boss 111, so as to move and discharge the mud and water ejected through the filter holes on the filter part 1111 to the cavity between the inner cylinder 11 and the outer cylinder 12 through the discharge ports 112. And the separation drum 1 is driven by the motor 5 to rotate at a high speed, so that the water and silt are thrown to the inner side surface of the outer cylinder 12 and will not adhere to the surface of the inner cylinder 11. After the inner cylinder 11 is taken out of the outer cylinder 12, the total weight of the inner cylinder 11 is weighed to obtain the mud content in the sand and gravel, or the gravel is taken out separately for calculation.

[0029] Moreover, an inclined surface part 122 is provided on the side surface of the outer cylinder 12, and a discharge hole 123 is provided on each of the left and right sides of the inclined surface part 122. A plug strip 124 is inserted into each discharge hole 123. The channels for discharging water vapor include the filter holes opened on the filter part 1111, the discharge ports 112 and the discharge holes 123. After the inner cylinder 11 is taken out, it can be placed obliquely so that the inclined surface part 122 is attached to the ground, and the positions of the discharge holes 123 on the left and right sides of the inclined surface part 122 are at the lowest positions, so that the silt and water between the inner cylinder 11 and the outer cylinder 12 flow out through the discharge holes 123, which is convenient for cleaning. The covering 13 includes a hot air blower 131 and an air outlet pipe 132. The air outlet pipe 132 is communicated with the air outlet of the hot air blower 131. The air outlet pipe 132 is arranged at the lower end of the covering 13. If it is necessary to accelerate the separation speed of the water in the separation drum 1, the covering 13 can be covered outside the outer cylinder 12 during the drying process of the mud and water, and the hot air blower 131 is started to discharge the hot air generated by it outward through the air outlet pipe 132 into the inner cylinder 11 and the outer cylinder 12 to accelerate the evaporation speed of the water.

[0030] Moreover, a 51 is sleeved on the output shaft of the motor 5. A corresponding inlaid tooth groove 127 is opened at the lower end of the outer cylinder 12. The inlaid tooth groove 127 is meshed with the 51. An inlaid convex tube 125 is provided on the lower inner surface of the outer cylinder 12. A corresponding centrifugal inlaid groove 113 is opened at the lower end of the inner cylinder 11. The inlaid convex tube 125 is embedded in the centrifugal inlaid groove 113. The centrifugal inlaid groove 113 is offset from the central axis of the inner cylinder 11. Therefore, when the inner cylinder 11 is driven to rotate through the centrifugal inlaid groove 113 offset from the central axis of the inner cylinder 11, the inner cylinder 11 rotates centrifugally, generating a greater centrifugal force and improving the efficiency of separating the mud and water.

[0031] However, a circular groove 126 that is recessed inward is formed on the lower end surface of the outer cylinder 12, and a corresponding raised ring 41 is provided on the surface of the frame body 4. When the separation drum 1 is mounted on the output shaft of the motor 5, the raised ring 41 is inserted into the circular groove 126, and the upper end of the raised ring 41 abuts against the inner upper end surface of the circular groove 126; both the raised ring 41 and the circular groove 126 are circularly arranged. When the separation drum 1 is arranged on the output shaft of the motor 5, the raised ring 41 can be used to provide a supporting force, and when the separation drum 1 is rotated, the raised ring 41 will not collide with the circular groove 126. And if it is necessary to remove the entire separation drum 1, the separation drum 1 can be directly removed from the output shaft of the motor 5, and the separation drum 1 can be removed from the motor 5 by making the inlaid tooth grooves 127 and 51 no longer engaged.

[0032] The above is only a preferred embodiment of the present invention, and thus the scope of implementation of the present invention cannot be limited thereby. That is, equivalent changes and modifications made according to the scope of the present invention patent and the content of the specification should still fall within the scope covered by the present invention.
