Description

Technical Field

[0001] This utility model relates to the field of concrete aggregate equipment technology, and in particular to a concrete aggregate processing device. Background Technology

[0002] Concrete aggregates (also known as aggregates) are granular loose materials that act as the skeleton or filler in concrete, accounting for 60% to 80% of the total volume of concrete. They have a decisive influence on the strength, durability, workability, and economy of concrete. The concrete aggregate processing flow mainly includes basic steps such as collection, crushing, screening, washing, and drying. Typically, naturally weathered or water-eroded rock particles or small pebbles from the sea or river are used. Larger rocks are crushed to 50mm–100mm using a rock crusher, then further processed into 20mm–40mm particles. These are then screened and classified according to their particle size, followed by further sorting and cleaning processes to meet the requirements for concrete use.

[0003] In existing technologies, concrete aggregates require manual collection and transportation from rock, followed by basic processes such as crushing, screening, washing, and drying. These processes often involve separate manual handling and sequential processing. This disjointed processing method easily leads to equipment idling or stagnation, resulting in relatively low processing efficiency and wasteful energy consumption. Therefore, there is a need for equipment that combines aggregate screening and washing, performing washing simultaneously with screening to save processing time and reduce resource consumption during aggregate transfer.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1-7As shown, this utility model discloses a concrete aggregate processing device, comprising a mounting base 1 and a frame 2 fixedly connected to the mounting base 1. The frame 2 includes a "door"-shaped frame 21, on which two pairs of connecting ears 46 are arranged in parallel. A fixing shaft 461 is fixedly connected to the inner side of each pair of connecting ears 46. The fixing shaft 461 is parallel to the mounting base 1. The frame 2 also includes a vertical pole 24 and two connecting plates 22 spaced apart within the "door"-shaped frame 21. A crossbar 23 is fixedly connected between the connecting plates 22 and the vertical pole 24. The two connecting plates 22 can increase the structural stability of the "door"-shaped frame 21 and provide certain support. The frame 2 is provided with a first sieve box 41 and a second sieve box 42. Each of the bottom outer sides of one end of the first sieve box 41 and the second sieve box 42 is connected to a second support block 47. A second bearing 471 is embedded in the center of the second support block 47, and the inner ring of the second bearing 471 is sleeved on the fixed shaft 461. This achieves the purpose of rotatably fixing one end of the first sieve box 41 and the second sieve box 42 to the "door" shaped frame 21.

[0020] Furthermore, each of the first screening box 41 and the second screening box 42 has a first support block 44 connected to its other side, and a first connecting shaft 431 is connected to the first support block 44. The bottom of the first screening box 41 is provided with a first filter screen 411, and the bottom of the second screening box 42 is provided with a second filter screen 421. The screen hole diameter of the first filter screen 411 is 11mm-40mm, and the screen hole diameter of the second filter screen 421 is 5mm-10mm. The first screening box 41 and the second screening box 42 can realize a two-stage screening process for concrete aggregates. The screen hole of the first filter screen 411 at the bottom of the first screening box 41 is larger, which can screen out aggregates with larger particle sizes, while aggregates with smaller particle sizes fall into the second screening box 42. Soil and dust on the surface of the aggregates will pass through the second filter screen 421, while the second screening box 42 retains the aggregates with smaller particle sizes. On the other side of the frame 2, two first connecting blocks 31 are vertically arranged. Each first connecting block 31 has a first bearing 311 in its center and a rotating shaft 32 connected to the inner ring of the first bearing 311. The other end of each rotating shaft 32 is fixedly connected to a turntable 33. A second connecting shaft 331 is fixedly connected to the edge of the turntable 33. A driving arm 45 is provided between the second connecting shaft 331 and the first connecting shaft 431. Each end of the driving arm 45 is provided with a third bearing 451, which is respectively sleeved on the second connecting shaft 331 and the first connecting shaft 431. When the turntable 33 is rotated, the second connecting shaft 331 on the turntable 33 will drive the driving arm 45 to move, thereby driving the first connecting shaft 431 to move, thereby driving the first screening box 41 and the second screening box 42 to rotate about the fixed shaft 461 as the rotation axis, shaking the aggregate in the screening box, thereby achieving the screening effect.

[0021] In this embodiment, a water storage tank 5 is provided on the mounting base 1, and a flushing structure 6 is provided above the water storage tank 5. The flushing structure 6 includes two spray ends 63, which are respectively located vertically above the first sieve box 41 and the second sieve box 42. The water storage tank 5 is located directly below the second sieve box 42. The flushing structure 6 also includes a main pipe 61 and two branch pipes 62 connected to the main pipe 61. The end of each branch pipe 62 is connected to the spray end 63. A high-pressure water pump 65 is connected to the lower section of the main pipe 61. The main pipe 61 is vertically arranged in the water storage tank 5, and a filter screen 67 is provided at its bottom. A clamp 66 is fitted on the outer side of the lower section of the main pipe 61. Four inclined support legs 11 are evenly fixed to the outer side of the clamp 66, and the four inclined support legs 11 are connected to the mounting base 1. The bottom of the main pipe 61 extends into the water storage tank 5. A high-pressure water pump 65 pumps water from the storage tank 5 into the main pipe, which is then sprayed out from two spray nozzles 63 to wash the aggregates in the first screening box 41 and the second screening box 42. The washed water, along with impurities and silt, flows through the screen holes at the bottom of the screening boxes and returns to the open-shaped water storage tank 5 under gravity, thus achieving water recycling. A filter screen 67 at the bottom of the main pipe 61 prevents particulate matter from entering the pipe and clogging the spray nozzles 63, thus affecting the washing effect of the two spray nozzles 63.

[0022] In this embodiment, the inner side of the "door"-shaped frame 21 is provided with two rotating doors 212. Each rotating door 212 has a hinge 211 fixedly connected to its top, and the other end of the hinge 211 is fixedly connected to the connecting plate 22 above it. One side panel of the first screening box 41 and the second screening box 42 is open, and the two rotating doors 212 correspond to the horizontal positions of the first screening box 41 and the second screening box 42, respectively. The rotating doors 212 and the open screening boxes together form a box-like enclosure, and the rotating doors 212 provide a discharge port for the aggregate inside the screening boxes. The rotating door 212 has a handle 2124 on the outer side of its bottom center. Below the handle 2124 are at least one second connecting block 2121 and a pin 2123. Each second connecting block 2121 is fixedly connected to the rotating door 212 and has a pin hole 2122 in its center. On the connecting plate 22 below the rotating door 212, a groove 213 matching the pin hole 2122 is formed to ensure that the pin 2123, after passing through the pin hole 2122, is inserted into the groove 213. The top and bottom of the rotating door 212 are fixed using hinges 211 and pins 2123 respectively, preventing aggregate from slipping from one side opening during screening and washing. After screening and rinsing, the pin hole 2122 is opened upwards, and the handle 2124 is pulled outwards to remove the aggregate from that side. A conveyor can also be connected to this side to transport the screened and washed aggregates to a designated location for drying, reducing the waste of manpower in manual handling.

[0023] It should be further explained that a transmission wheel 35 is fixedly connected to the other end of each of the rotating shafts 32, and the transmission wheel 35 is located inside the turntable 33. A transmission belt 36 is provided between two corresponding transmission wheels 35 in the vertical direction. A motor 37 is fixedly connected to the bottom of the upright 24, and the output shaft of the motor 37 is fixedly connected to the rotating shaft 32 located below. When the motor 37 is started, under the action of the transmission belt 36 and the transmission wheel 35, the upper and lower turntables 33 rotate simultaneously, thereby enabling the first screening box 41 and the second screening box 42 to synchronously shake the screened material. Using a single motor to control multiple screening boxes saves energy consumption and reduces production costs.

[0024] This invention utilizes a first and second sieve box, along with spray nozzles above them, and a flushing structure including pipes and a high-pressure water pump connected to the spray nozzles. This allows the concrete aggregate to be screened simultaneously while pressure water from the spray nozzles cleans the surface of clay and fine impurities, improving aggregate purity and concrete quality. Through the step-by-step screening in the first and second sieve boxes, the aggregate undergoes two screening processes, separating aggregates of different particle sizes to meet the required fineness of aggregates in various concrete applications. Furthermore, by inserting the main pipe of the flushing structure into a water storage tank and installing a filter screen at its bottom, the flushing water and impurities from the first and second sieve boxes flow back into the water storage tank. The flushing structure then filters the water in the tank and reuses it for washing the aggregate, achieving water reuse and meeting the environmentally friendly production requirements of water conservation. This invention solves the technical problems of discontinuous processing and relatively low processing efficiency in concrete aggregate processing. It shortens the overall processing time of concrete aggregates, saves space occupied by screening and cleaning equipment, improves the production efficiency of concrete aggregates, and enhances economic benefits.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
