Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to an impurity screening machine for concrete manufacturing. Background Art
[0002] During concrete production and construction, raw materials often contain various impurities, such as rocks, sand, soil, and sawdust. These impurities not only affect the quality and performance of the concrete but can also damage construction equipment and reduce efficiency. Therefore, screening concrete raw materials for impurities is crucial to ensuring concrete quality and smooth construction.
[0003] The existing technical problems are as follows:
[0004] 1. Low screening efficiency: Traditional screening methods often use a single screen or simple mechanical vibration, which has a slow screening speed and cannot meet the needs of large-scale construction.
[0005] 2. The screening accuracy is not high: Since the aperture of the screen is fixed and single, it is difficult to effectively separate impurities of different particle sizes, resulting in the concrete raw materials after screening still containing a lot of impurities.
[0006] 3. High labor intensity: Manual screening requires a lot of manpower and time, and the working environment is harsh, which has a certain impact on the health of the operators.
[0007] 4. Difficulty in equipment maintenance: Traditional screening equipment has a complex structure and is difficult to repair and maintain. Once a failure occurs, it often takes a long time and high cost to repair.
[0008] 5. Poor adaptability: Traditional screening equipment is difficult to adjust and optimize according to the characteristics of different raw materials and impurities, and has poor adaptability. Utility Model Content
[0009] The purpose of the utility model is to provide an impurity screening machine for concrete manufacturing to solve the problems raised in the above background technology.
[0010] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an impurity screening machine for concrete manufacturing, comprising a screening box, a feed hopper fixedly installed on the top of the screening box, and two groups of first screen frames, second screen frames and third screen frames symmetrically arranged in sequence from top to bottom in the screening box, the bottoms of the first screen frames, the second screen frames and the third screen frames are all fixedly provided with screens, the tops of the screens are fixedly provided with a number of trapezoidal blocks, the two sides of the screening box are sequentially provided with a first aggregate box, a second aggregate box and a third aggregate box from top to bottom, and a fourth aggregate box is placed at the bottom of the screening box.
[0011] Maintenance doors are fixedly provided on the front and rear sides of the screening box through connecting plates, and a plurality of handles are fixedly provided on the maintenance doors. The outer sides of the first screen frame, the second screen frame and the third screen frame are all clamped with limit blocks, and the limit blocks are fixedly provided on the inner sides of the maintenance doors.
[0012] There are two feed hoppers, and the two feed hoppers are symmetrically arranged.
[0013] The specifications of the first screen frame, the second screen frame and the third screen frame are consistent. The apertures of the screens in the first screen frame, the second screen frame and the third screen frame become smaller in sequence, and a vibrator is fixedly provided at the bottom of the screen.
[0014] One side of the first material collection box, the second material collection box and the third material collection box is movably provided with a detachable door.
[0015] Compared with the prior art, the beneficial effects of the present invention are:
[0016] The utility model can efficiently separate impurities of different particle sizes through multi-stage screen frames and gradually smaller screen apertures, thereby improving screening accuracy and efficiency. The closed structure of the screening box, the symmetrically arranged feed hopper and screen frame, and the design for easy maintenance and cleaning all make the entire screening machine reasonable in structure and easy to operate. The trapezoidal blocks are used to increase the rigidity and stability of the screen, while also contributing to the distribution and flow of raw materials on the screen and slowing down the speed of movement during vibration. The vibrator is used to vibrate the screen, which contributes to the distribution and flow of raw materials on the screen and further improves the screening effect.
