Description

Technical Field

[0001] The invention relates to the technical field of concrete production, and in particular to a concrete wet screening device. Background Art

[0002] Hydraulic structures often use three-grade or four-grade concrete, and the maximum aggregate size can reach 80 to 150 mm. When conducting indoor tests on hydraulic concrete materials, if the original graded specimens are used, the specimen size is often large, which increases the difficulty of the test and the cost. Therefore, the wet screening method is generally used at home and abroad to screen out coarse aggregates above 40 mm in the original graded specimens to make wet-screened specimens with standard sizes, and conduct static and dynamic performance tests on hydraulic concrete, and this index is regarded as the mechanical index of hydraulic concrete. The hydraulic concrete test code (SL / T352-2020) stipulates: "If the aggregate particle size exceeds 1 / 3 of the minimum size of the mold cavity, the large aggregate should be screened out by wet screening before molding." Therefore, when preparing concrete mixtures for indoor tests, it is necessary to remove large aggregates with a particle size exceeding the requirement before molding to meet the requirements of the specification. The concrete wet screening device is a device used to screen out aggregates with a particle size exceeding the requirement in concrete. Its main function is to separate the aggregate and matrix with particle size exceeding the requirement in the concrete mixture through the screening device under the vibration of the vibration motor, and then to mold and vibrate the concrete into shape. After demolding, the concrete is placed in the standard curing room for curing to the test age. After the curing is completed, the mechanical properties test of wet-screened concrete is carried out. It is currently widely used in construction, concrete production and related laboratory testing.

[0003] Most of the existing concrete wet screening devices achieve the purpose of screening by vibrating and rolling the concrete mixture. Each screening must be stopped after the last added mixture is screened, and then the new mixture must be added again to continue screening. This operation process is relatively cumbersome and inefficient, which is not conducive to continuous operation of the experiment, and it is both manpower-consuming and time-consuming. At the same time, the screen of the existing concrete wet screening device is usually welded in the screening box, and the screen hole size is fixed. When it is necessary to screen out materials of a specific size, it is necessary to replace the specific screen, which is cumbersome to operate and has poor flexibility. Secondly, after the screening is completed, it is inconvenient to clean the mortar remaining on the surface of the screen, which affects the normal use of subsequent experiments. In view of this, it is urgent to design a device that can automatically wet screen concrete. Summary of the invention
