Description

Technical Field

[0001] The invention relates to the technical field of cleaning equipment for building sand and gravel, in particular to a water-washing device for building sand and gravel. Background Art

[0002] Construction gravel is one of the commonly used aggregates in construction projects. It is mainly composed of small particles of stone and sand, with a particle size usually below 5 mm. It plays an important role in concrete, mortar and other building materials, providing the necessary strength and stability. There are various types of construction gravel, including natural gravel and artificial gravel. The former usually comes from natural environments such as rivers and beaches, while the latter is processed from crushed stone or other materials. When construction gravel is used to make concrete, mortar and other building materials, it will first be pre-treated by a construction gravel water washing device to separate and wash away the soil impurities on the surface.

[0003] However, when cleaning the gravel, some lighter impurities will adhere to the surface of the gravel. When the gravel is cleaned in the water washing drum, some impurities will fall off the surface of the gravel and be discharged from the water washing drum with the sewage, but some stubborn impurities will adhere to the surface of the gravel and are not easy to clean off. Usually, the gravel will be soaked and cleaned again to separate the stubborn impurities from the gravel. Some small particles of impurities are lighter in size and will float on the surface of the water. If they are not cleaned and collected in time, these floating impurities will adhere to the surface of the gravel again due to gravity when the water is discharged, which is not convenient for effectively discharging impurities before the gravel is discharged, reducing the cleaning efficiency and quality. For this reason, we propose a water washing device for construction gravel. Summary of the Invention

DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-Figure 5 and Figure 10 The present invention provides a technical solution: a construction gravel washing device, comprising a base 1 and a hopper 5, a first frame 2, a second frame 3 and a soaking box 4 are installed above the base 1, the soaking box 4 can soak and precipitate the gravel after washing it, so that the stubborn small particles of impurities adhering to the surface of the gravel float in the water, a washing drum 7 for washing the gravel is installed in the middle of the first frame 2, a hopper 5 for storing gravel is installed on the top of the second frame 3, the bottom end of the hopper 5 is connected to the top of the washing drum 7, and the hopper 5 and the washing drum 7 cooperate with each other. It can discharge and dynamically clean the gravel. The inner wall of the water washing cylinder 7 is provided with a cavity channel and a through hole for water to flow through. The water flows into the inner cavity of the water washing cylinder 7 from the through hole to clean the gravel and wash away the large particles of dirt on the surface of the gravel. The interior of the water washing cylinder 7 is equipped with an auger transmission component 11 for conveying and dynamically cleaning the gravel. One end of the bottom of the water washing cylinder 7 is connected to a No. 2 drain pipe 14 for discharging cleaning sewage, and the other end of the bottom of the water washing cylinder 7 is connected to a drop pipe 13 for conveying gravel.

[0020] During use, the hopper 5 stores the gravel, and the hopper 5 conveys the gravel into the water washing drum 7, and then conveys the water into the cavity channel of the water washing drum 7 through the external water flow conveying equipment. At the same time, the auger transmission component 11 rotates to convey the gravel from one end to the other end. With the help of water flushing, the large particles of dirt on the outer surface of the gravel can be cleaned, and the sewage can be discharged to the outside of the water washing drum 7 through the No. 2 drain pipe 14. The cleaned gravel is discharged into the soaking box 4 through the drop pipe 13 for soaking operation, so that the stubborn small particles of impurities adhering to the surface of the gravel float in the water, thereby separating from the gravel and improving the cleaning quality.

[0021] See also Figure 1-Figure 5 and Figure 10, a moving mechanism 6 is installed on the top of the immersion box 4, which can drive the U-shaped frame 23 to move horizontally. The moving mechanism 6 includes a bracket 604 symmetrically arranged on the top of the immersion box 4, and a screw rod 601 for the horizontal movement of the movable frame 603 is installed on one side of the bracket 604 through a bearing. A threaded socket structure is formed between the screw rod 601 and the movable frame 603, and a moving motor 602 connected to the screw rod 601 through a coupling is installed on the outer side of the bracket 604. The moving motor 602 drives the screw rod 601 to rotate and drives the movable frame 603 to move horizontally. A sliding rod 605 fixedly connected to the bracket 604 is provided on the symmetrical side of the screw rod 601, and a sliding structure is formed between the slide rod 605 and the movable frame 603. The slide rod 605 cooperates with the screw rod 601 to stably guide the horizontal movement of the movable frame 603.

[0022] When in use, the moving motor 602 is started, and the moving motor 602 drives the screw rod 601 to rotate. At the same time, the screw rod 601 is threadedly engaged with the moving frame 603, so that one end of the moving frame 603 moves laterally outside the screw rod 601, and at the same time, the other end of the moving frame 603 slides laterally outside the sliding rod 605, so that the moving frame 603 can drive the electric telescopic rod 10 to move laterally, and then the U-shaped frame 23 drives the collecting frame 19 to move laterally stably, so as to pick up small particles of impurities floating on the water surface, prevent the impurities from sinking into the gravel again, and ensure that the final gravel is cleaner.

[0023] See also Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 and Figure 7-10 , an electric telescopic rod 10 for driving the U-shaped frame 23 to rise and fall is installed in the middle of the mobile frame 603, and a collection frame 19 for scooping small particles of impurities floating on the water surface of the immersion box 4 is provided below the U-shaped frame 23, and a plurality of filter holes are opened on the inner wall of the collection frame 19, through which water can flow out and collect small particles of impurities in the inner cavity. The two ends of the collection frame 19 are connected with a movable shaft that runs through the inner walls of the U-shaped frame 23 on both sides. The end of the movable shaft away from the collection frame 19 is fixedly connected with a guide wheel 25, and the teeth on the outer side of the guide wheel 25 are unevenly distributed, and at least one edge area is not provided with teeth. Blocks form an asymmetric gear structure, and the guide wheel 25 plays a role in guiding the flipping movement of the collecting frame 19. Guide grooves 24 that form a sliding structure with the guide wheel 25 are provided on the inner walls on both sides of the soaking box 4. The guide groove 24 is set in a Hui shape, and one end extends upward. Saw teeth 26 with equal intervals are fixed in the inner wall of the end of the guide groove 24 extending upward, and the saw teeth 26 are meshed with the guide wheel 25. The edge of the guide wheel 25 without a tooth block is in contact with the inner wall of the guide groove 24. The guide groove 24 can prevent the guide wheel 25 from rotating when the guide wheel 25 moves laterally.

[0024] During specific implementation, while the movable frame 603 drives the electric telescopic rod 10 and the U-shaped frame 23 to move laterally, the U-shaped frame 23 also drives the collection frame 19 to move laterally, and the collection frame 19 scoops up the floating particulate impurities. Since the U-shaped frame 23 and the movable shaft are movably connected, and the movable shaft is connected to the guide wheel 25, the U-shaped frame 23 drives the guide wheel 25 to move laterally in the guide groove 24. The edge of the guide wheel 25 without a tooth block is in contact with the inner wall of the guide groove 24. The guide groove 24 limits the rotation of the guide wheel 25, thereby preventing the collection frame 19 from shaking. When the guide wheel 25 reaches the position where the guide groove 24 extends upward, the electric telescopic rod 10 lifts the U-shaped frame 23 upward, so that the U-shaped frame 23 drives the guide wheel 25 to enter the upward extending end of the guide groove 24, and then the tooth block of the guide wheel 25 engages with the saw teeth 26, driving the guide wheel 25 to rotate clockwise. At the same time, the guide wheel 25 drives the collecting frame 19 to rotate clockwise through the movable shaft, causing the collecting frame 19 to flip over, and impurities fall on the surface of the guide plate 16, thereby dumping the impurities in the collecting frame 19 or facilitating cleaning by the staff. The collection frame 19 can be flipped, making the cleaning process simple and quick, reducing the frequency of manual cleaning of impurities, reducing labor intensity, and improving the work efficiency of sand and gravel washing.

[0025] See also Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 and Figure 7-10 A water inlet pipe 12 for conveying water is installed on the outer wall of the immersion box 4, and the bottom end of the immersion box 4 is connected to a No. 1 drain pipe 9 for discharging water. A guide plate 16 for guiding small particles of impurities is installed at the opening on one side of the immersion box 4. The collection frame 19 flips over to pour the small particles of impurities onto the guide plate 16 for cleaning by the staff. A discharge door 17 for discharging gravel is installed on the outer wall of one side of the immersion box 4 below the guide plate 16 through a hinge. The opening and closing of the discharge door 17 can discharge gravel or block the outflow of water. A water level line 22 in a groove structure is opened on the inner wall of the immersion box 4 near the guide groove 24. The water level line 22 is the maximum limit of the water level of the immersion box 4.

[0026] During use, the water inlet pipe 12 conveys water into the soaking box 4. The water level line 22 allows the staff to observe the water level conveniently. The maximum water level cannot be higher than the water level line 22 to soak the gravel. After the soaking work is completed, large particles of impurities are deposited on the bottom surface of the soaking box 4. The No. 1 drain pipe 9 discharges the sewage and large particles of impurities from the soaking box 4, and then the discharge door 17 is opened, and the gravel is discharged from the discharge door 17 to complete the soaking and discharging work.

[0027] See also Figure 2 and Figure 4-Figure 6The immersion box 4 is located on the inner wall of the bottom end and is equipped with a rotating shaft 18 through a bearing. The outer side of the rotating shaft 18 is fixedly sleeved with a receiving plate 20 for separating sand and gravel and large particles of impurities. The inner side of the receiving plate 20 is provided with a plurality of holes. The receiving plate 20 plays the role of guiding sand and gravel and separating large particles of impurities in the immersion box 4. The outside of the immersion box 4 is equipped with a discharge motor 15 connected to the rotating shaft 18 through a coupling. The discharge motor 15 drives the rotating shaft 18 to rotate and drives the receiving plate 20 to rotate, which is used to auxiliary guide the cleaned sand and gravel to the discharge door 17 for discharge.

[0028] During specific implementation, the gravel enters the soaking box 4 through the drop pipe 13, and then falls above the receiving plate 20, and then the soaking operation is carried out. Small particles of impurities float to the water surface, and large particles of impurities fall from the holes of the receiving plate 20 to the bottom of the soaking box 4. The receiving plate 20 separates the gravel and large particles of impurities. After the soaking work is completed, the discharge motor 15 is started to drive the rotating shaft 18 to rotate, and the rotating shaft 18 drives the receiving plate 20 to rotate. The gravel on the receiving plate 20 is discharged from the discharge door 17. Through the setting of the receiving plate 20, it can improve the soaking quality and also facilitate rapid discharge, thereby improving the practicality of the construction gravel water washing device.

[0029] See also Figure 4 、 Figure 5 and Figure 10-12 The immersion box 4 is located in the inner cavity above the material receiving plate 20 and is fixed with a symmetrically distributed fixing frame 21. A stirring mechanism 8 for stirring gravel and water is installed in the middle of the fixing frame 21. The stirring mechanism 8 includes a transmission shaft 802 installed in the middle of the fixing frame 21 through a bearing. The top of the transmission shaft 802 is fixedly sleeved with a turntable 801. The bottom end of the collecting frame 19 is fixedly welded with a rack 27 that forms a meshing connection structure with the turntable 801. The collecting frame 19 moves laterally and drives the rack 27 to engage with the turntable 801, driving the transmission shaft 802 to rotate.

[0030] When in use, when the moving mechanism 6 drives the collecting frame 19 to move toward the guide plate 16, the height of the collecting frame 19 and the rack 27 is higher than the height of the turntable 801, so the turntable 801 will not be driven to rotate when scooping up floating impurities. When the collecting frame 19 flips over to dump and clean out the collected small particles of impurities, the electric telescopic rod 10 pushes the U-shaped frame 23 downward, so that the U-shaped frame 23 drives the guide wheel 25 to move downward until the guide wheel 25 enters the lowest end of the guide groove 24, and the moving mechanism 6 drives the collecting frame 19 to move back to its original position, so that the collecting frame 19 drives the rack 27 to engage with the turntable 801, driving the turntable 801 to rotate, which can disturb the water again and promote the remaining small particles of impurities in the sand and gravel to rise and float to the water surface again. The process of scooping and stirring is repeated many times, which reduces the retention time of small particles of impurities and prevents floating impurities from adhering to the surface of the sand and gravel again.

[0031] See also Figure 11-14 The bottom end of the transmission shaft 802 is connected to a sleeve rod 807 by a bolt. The sleeve rod 807 is set as a square column structure. The outer side of the sleeve rod 807 is slidably sleeved with a stirring paddle 805 for stirring gravel and water. The transmission shaft 802 drives the sleeve rod 807 to rotate. The sleeve rod 807 drives the stirring paddle 805 to rotate by generating torque. The stirring paddle 805 stirs and disturbs the water, enhances the mutual collision between particles in the water, and thus makes small particles of impurities suspended on the water surface. The bottom of the fixed frame 21 is welded A fixed cylinder 803 is connected to the outside of the stirring paddle 805. The inner wall of the fixed cylinder 803 is provided with a lifting groove 806 in a ring structure, and the lifting groove 806 is set to an inclined shape. A round block 804 is fixed on one side of the stirring paddle 805 to form a sliding connection structure with the lifting groove 806. When the stirring paddle 805 rotates, it can drive the round block 804 to slide along the lifting groove 806, so that the round block 804 drives the stirring paddle 805 to rise and fall, thereby breaking up the accumulated sand and gravel for rapid discharge.

[0032] During use, as the stirring paddle 805 rotates, the stirring paddle 805 drives the round block 804 to rotate at the same time, and the round block 804 slides along the circular trajectory of the lifting groove 806. At the same time, the stirring paddle 805 slides along the outer wall of the sleeve rod 807, so that the stirring paddle 805 moves up and down and rotates as the sleeve rod 807 rotates, which can break up the accumulated gravel and enhance the vortex effect of the water, promote the suspension of small particles of impurities, facilitate the collection of the collection frame 19, enhance the working efficiency of the stirring paddle 805, improve the cleaning efficiency and work quality of the building gravel washing device, and reduce energy consumption.

[0033] The sand washing machine 10 is a kind of water washing machine 10, which is used to wash the sand and gravel in the water. The sand and gravel are washed and cleaned by the hopper 5. The sand and gravel are washed and cleaned by the hopper 5. The washing water in the washing drum 7 is discharged from the second drain pipe 14, and the sand and gravel are discharged from the drop pipe 13 into the soaking box 4 for soaking and sedimentation. The moving mechanism 6 drives the collecting frame 19 to move horizontally to scoop up the floating small particles of impurities and flip them over and dump them out. In the process of the collecting frame 19 returning to its original position, the stirring mechanism 8 is driven to rise and fall and rotate to stir, thereby enhancing the fluidity of the water, so that the remaining small particles of impurities float up again, and at the same time, the accumulated sand and gravel are broken up. After the scooping and stirring cycles are repeated many times, the water body stops, and the large particles of impurities fall from the holes of the receiving plate 20 to the bottom of the soaking box 4, and finally the water body is discharged through the first drain pipe 9, and then the receiving plate 20 is rotated and tilted to discharge the cleaned sand and gravel from the discharge door 17, completing the washing of the construction sand and gravel. The content not described in detail in this specification belongs to the existing technology well known to professional and technical personnel in this field.
