Description

Technical Field

[0001] This utility model relates to the technical field of concrete aggregate pretreatment equipment, specifically a concrete aggregate pretreatment device. Background Technology

[0002] In the concrete preparation process, the quality of aggregates has a crucial impact on the performance of concrete. However, natural aggregates often contain clay, which reduces the bond strength between the aggregates and cement paste, affecting the strength, durability, and other properties of the concrete.

[0003] Traditional aggregate cleaning methods mainly rely on manual labor or simple mechanical equipment, which has many problems. Manual cleaning is inefficient, labor-intensive, and the cleaning effect is difficult to guarantee; while existing mechanical equipment cleaning methods mostly have the disadvantages of incomplete cleaning and serious waste of water resources. For example, a concrete aggregate cleaning device disclosed in Chinese patent application number CN202410565703.2 only uses simple rinsing to clean the aggregates.

[0004] Therefore, we need to propose a concrete aggregate pretreatment device. Utility Model Content

[0005] The purpose of this invention is to provide a concrete aggregate pretreatment device, in which a shaft drives multiple sets of mixing rods to mix the aggregate while spraying and rinsing, so that the aggregate and water are in full contact, which can accelerate the separation of impurities. Compared with traditional cleaning methods, this greatly improves the cleaning efficiency of aggregate, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A concrete aggregate pretreatment device, comprising:

[0008] A water tank, wherein the top of the water tank is provided with a rim, and a first protruding plate and a second protruding plate are respectively provided on the top two sides of the rim;

[0009] The cleaning chamber is rotatably positioned between the first and second convex plates, and filter holes are distributed at the bottom of the cleaning chamber to allow mud and water to pass through.

[0010] A support plate is provided on the top side of the surrounding edge, and the support plate is arranged in an inverted L shape;

[0011] A cleaning mechanism is installed on the outer wall of the support plate. The cleaning mechanism includes a water pump. A spray pipe is installed at the bottom of the upper end of the support plate. Multiple sets of nozzles are installed at the bottom of the spray pipe facing the top opening of the cleaning chamber. The water pump draws water from the water tank and delivers it to the spray pipe to wash the aggregate in the cleaning chamber.

[0012] Preferably, it also includes a filter cover, which is set at the junction of the perimeter and the water tank. The mud and water in the cleaning chamber are discharged through the filter holes and filtered by the filter cover before flowing back to the water tank for recycling.

[0013] Preferably, it also includes a stirring mechanism, which is disposed inside the cleaning chamber. The stirring mechanism includes a shaft and stirring rods. The shaft is rotatably mounted between the inner walls on both sides of the cleaning chamber via bearings. Multiple sets of stirring rods are arranged around the outer wall of the shaft to stir the aggregate while spraying and rinsing to improve cleaning efficiency.

[0014] Preferably, it also includes a motor, which is installed on the outer wall of the first convex plate. The two ends of the shaft extend to the outside of the cleaning chamber and are rotatably connected to the first convex plate and the second convex plate respectively through bearings. One end of the shaft is connected to the output end of the motor through a coupling.

[0015] Preferably, it also includes a protrusion disposed on the top of the second protruding plate. The cleaning chamber is located on one side of the outer wall of the second protruding plate and a positioning block is provided. When cleaning the aggregate, the protrusion and the positioning block abut together and are locked together by fixing screws.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] Water is pumped from the tank and delivered to the spray pipes. The spray nozzles then rinse the aggregate in the cleaning chamber, achieving an automated cleaning process and avoiding the inefficiency of manual cleaning. An agitation mechanism is installed inside the cleaning chamber. The shaft drives multiple agitators to agitate the aggregate while it is being sprayed, ensuring full contact between the aggregate and water and accelerating the separation of impurities.

[0024] 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.

[0025] Please see Figure 1-4 This utility model provides a technical solution:

[0026] A concrete aggregate pretreatment device, comprising:

[0027] Water tank 1, the top of water tank 1 is provided with a rim 2, and the top two sides of the rim 2 are respectively provided with a first protruding plate 9 and a second protruding plate 10;

[0028] The cleaning chamber 3 is rotatably positioned between the first convex plate 9 and the second convex plate 10. The bottom of the cleaning chamber 3 is provided with filter holes 11 for mud and water to pass through.

[0029] Support plate 4 is set on the top side of the perimeter 2, and the support plate 4 is set in an inverted L shape;

[0030] A cleaning mechanism is installed on the outer wall of the support plate 4. The cleaning mechanism includes a water pump 5. A spray pipe 6 is installed at the bottom of the upper end of the support plate 4. Multiple sets of nozzles 7 are installed at the bottom of the spray pipe 6, facing the top opening of the cleaning chamber 3. The water pump 5 draws water from the water tank 1 and delivers it to the spray pipe 6 to rinse the aggregate in the cleaning chamber 3. The water inlet end of the water pump 5 is connected to an inlet pipe, the end of which extends to the bottom of the water tank 1. The water outlet end of the water pump 5 is connected to an outlet pipe, the end of which is connected to the top of the spray pipe 6.

[0031] When the water pump 5 is working, it draws water from the water tank 1 through the inlet pipe, delivers it to the spray pipe 6 through the outlet pipe, and then sprays it out from the nozzle 7 to wash the aggregate in the cleaning chamber 3. The mud in the aggregate mixes with the water to form mud water, which is then discharged through the filter hole 11.

[0032] In summary, the system provides high-pressure water flow for aggregate cleaning, and through the spraying action of nozzle 7, it achieves a comprehensive rinsing of the aggregate surface, removes impurities from the aggregate surface, and ensures the cleaning effect.

[0033] For a preferred implementation, please refer to Figure 1-3 It also includes a filter cover 8, which is set at the junction of the perimeter 2 and the water tank 1. The mud and water in the cleaning chamber 3 are discharged through the filter hole 11 and filtered by the filter cover 8 before flowing back to the water tank 1 for recycling.

[0034] The filter cover 8 is set at the junction of the perimeter 2 and the water tank 1. After the mud and water in the washing chamber 3 are discharged through the filter holes 11, the filter cover 8 filters out the impurities in the mud and water, and the filtered water flows back to the water tank 1. This realizes the recycling of water resources. By filtering out the impurities in the mud and water, the filtered water can be pumped by the water pump 5 again for washing aggregates, reducing water waste and lowering production costs.

[0035] For a preferred implementation, please refer to Figure 1-4 It also includes a stirring mechanism, which is located inside the cleaning chamber 3. The stirring mechanism includes a shaft 13 and a stirring rod 14. The shaft 13 is rotatably mounted between the inner walls on both sides of the cleaning chamber 3 via bearings. Multiple sets of stirring rods 14 are arranged around the outer wall of the shaft 13. The stirring mechanism stirs the aggregate while spraying and rinsing to improve the cleaning efficiency.

[0036] When the motor 12 starts, it drives the shaft 13 to rotate, which in turn drives the stirring rod 14 to stir the aggregate in the cleaning chamber 3. While spraying and rinsing, the aggregate is stirred, so that the aggregate and water come into full contact, accelerating the separation of impurities. At the same time, it can break up larger soil particles, and the aggregate can generate mutual friction, improving the cleaning efficiency and ensuring that the aggregate is cleaned more thoroughly.

[0037] For a preferred implementation, please refer to Figure 4 It also includes a motor 12, which is installed on the outer wall of the first convex plate 9. The two ends of the shaft 13 extend to the outside of the cleaning chamber 3 and are rotatably connected to the first convex plate 9 and the second convex plate 10 respectively through bearings. One end of the shaft 13 is connected to the output end of the motor 12 through a coupling.

[0038] When the motor 12 is powered on, its output end drives the coupling to rotate, which in turn drives the shaft 13 to rotate, providing power to the mixing mechanism and enabling the mixing rod 14 to rotate normally, thus realizing the mixing operation of the aggregate in the washing chamber 3. This is the power source for the normal operation of the mixing mechanism.

[0039] For a preferred implementation, please refer to Figure 2-4 It also includes a protrusion 15, which is set on the top of the second protruding plate 10. The cleaning chamber 3 is located on one side of the outer wall of the second protruding plate 10 and is provided with a positioning block 16. When cleaning the aggregate, the protrusion 15 and the positioning block 16 abut together and are locked together by fixing screws. When unloading, the fixing screws are removed and the cleaning chamber 3 is flipped to one side and poured into the prepared container.

[0040] The protrusion 15 is located on the top of the second protruding plate 10, and the cleaning chamber 3 is located on one side of the outer wall of the second protruding plate 10 with a positioning block 16. When cleaning the aggregate, the cleaning chamber 3 is adjusted to a suitable position (the opening of the cleaning chamber 3 faces directly upward), so that the protrusion 15 and the positioning block 16 abut together, and then the two are locked together by fixing screws. At this time, the cleaning chamber 3 is in a stable cleaning state. When unloading, the fixing screws are removed, the cleaning chamber 3 loses its fixed constraint, and can be flipped to one side to pour the cleaned aggregate into the prepared container.

[0041] In summary, during aggregate cleaning, the cleaning chamber 3 is kept stable by the cooperation of the protrusion 15, the positioning block 16 and the fixing screw, ensuring the smooth progress of the cleaning process; during material unloading, the cleaning chamber 3 can be easily and quickly flipped over to achieve rapid material unloading and improve operating efficiency.

[0042] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
