Description

Technical Field

[0001] This invention relates to the field of concrete production technology, specifically to an aggregate cleaning device and cleaning method for concrete production. Background Technology

[0002] Concrete is a building material used in construction. The production of concrete involves mixing aggregates, cement, sand, and water. Aggregates, often called crushed stone, often have a lot of dust and impurities adhering to their surface. These dust and impurities cannot react with water during mixing, which can affect construction quality. Therefore, to ensure high-quality concrete production, the surface of the crushed stone is cleaned to remove dust and other impurities, ensuring a precise ratio between the crushed stone, cement, and water.

[0003] In general construction, aggregates are cleaned by water flow and mixing devices during the washing process. However, due to the large amount of dust and impurities on the surface of the aggregates, and the slow reaction of the surface after the aggregates come into contact with the water flow, the impurities are not easy to fall off. As a result, the suspended matter washed away by the water flow re-adheres to the surface of the aggregates, which leads to a reduction in the quality of the aggregates after washing. Therefore, a device is needed to avoid the above situation.

[0004] Therefore, it is essential to design a concrete aggregate cleaning equipment and method that is highly practical and can reduce the amount of suspended impurities adhering to the surface of the aggregate after cleaning. Summary of the Invention

[0005] The purpose of this invention is to provide aggregate cleaning equipment and cleaning method for concrete production, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a concrete aggregate cleaning device and cleaning method, comprising a mounting frame, a fixed shell fixedly connected to the upper side of the mounting frame, the left side height of the fixed shell being less than the right side height of the fixed shell, a drain outlet opening on the left side of the fixed shell, a water pipe bracket fixedly connected to the left side of the fixed shell, a water pipe fixedly connected to the upper side of the water pipe bracket, a drain outlet opening on the lower side of the water pipe, the right end of the water pipe extending to the upper middle part of the fixed shell, the drain outlet communicating between the left side of the fixed shell and the interior of the fixed shell, an inner plate fixedly connected to the upper side of the inner wall of the fixed shell, and the lower side of the inner plate being connected to... The outer wall of the fixed shell does not contact the inner plate. An installation port is provided on the left side of the inner plate. A filter screen is installed inside the installation port.

An anti-adhesion mechanism is also provided on the upper surface of the mounting frame.

[0007] According to the above technical solution, the anti-adhesion mechanism includes a fixing block, the outer wall of the fixing block is fixedly connected to the outer wall of the mounting frame, a motor is fixedly connected to the inner wall of the fixing block, a rotating plate is fixedly connected to the output end of the motor, a hinge rod is rotatably connected to the outer wall of the rotating plate through a bearing, a lifting rod is hinged to the other end of the hinge rod, the upper end of the lifting rod penetrates through the fixing shell and extends to the upper side of the fixing shell and is hinged to the lower surface of the filter screen, the outer wall of the filter screen contacts the inner wall of the mounting port, a toggle mechanism is provided on the lower right side of the inner plate, and an exhaust mechanism is provided on the left side of the rotating plate.

[0008] According to the above technical solution, the connection between the hinge rod and the rotating plate is not at the center of the rotating plate, and the hinge rod and the lifting rod can be dragged up and down when the rotating plate rotates. The outer wall of the lifting rod that penetrates the fixed shell contacts the inner wall of the fixed shell, and the lower surface edge of the filter screen protrudes downward.

[0009] According to the above technical solution, the exhaust mechanism includes a first pressure plate, the lower surface of which is slidably connected to the outer wall of the mounting bracket, and the outer wall of the first pressure plate is in contact with the outer wall of the hinge rod. An air bladder is fixedly connected to the side of the outer wall of the first pressure plate away from the hinge rod, and a second pressure plate is fixedly connected to the other side of the air bladder. A one-way valve is provided on the second pressure plate, the input side of which is the side away from the air bladder. A first spring is fixedly connected to the side of the outer wall of the second pressure plate near the first pressure plate, and the other end of the first spring is fixedly connected to the outer wall of the first pressure plate. The first spring is located inside the airbag, and the second pressure plate is fixedly connected to a main air pipe on the side away from the first pressure plate. The upper end of the main air pipe is fixedly connected to a secondary air pipe, one side of which extends to the lower side of the filter screen. An exhaust pipe is fixedly connected to the upper side of the secondary air pipe. The upper end of the exhaust pipe passes through the filter screen and communicates with the upper side of the filter screen. A waterproof one-way valve is fixedly connected to the upper side of the inner wall of the exhaust pipe. The interior of the exhaust pipe communicates with the interior of the airbag through the secondary air pipe and the main air pipe. The output side of the waterproof one-way valve is the upper side.

[0010] According to the above technical solution, the actuating mechanism includes a first inclined block, the outer wall of the first inclined block is fixedly connected to the lower right surface of the filter screen, the lower side of the first inclined block contacts a second inclined block, and the lower surface of the second inclined block is slidably connected to the outer wall of the fixed shell, the upper surface of the second inclined block contacts the lower side of the outer wall of the inner plate, a lever is fixedly connected to the upper surface of the second inclined block, the upper side of the lever extends through a strip-shaped opening to the upper side of the inner plate, a second spring is fixedly connected to the right end of the second inclined block, a stop is fixedly connected to the right side of the second spring, and the lower side of the stop is fixedly connected to the outer wall of the inner plate.

[0011] According to the above technical solution, the conveying blade is provided with an inclined conveying blade, and there are two rotating rods. The conveying blades on the two rotating rods are staggered. The toggle block is located between the conveying blades on both sides. The outer wall of the second inclined block and the outer wall of the first inclined block are both inclined on the side that are close to each other. When the filter screen descends, it can be moved by the first inclined block pushing the second inclined block.

[0012] A method for cleaning aggregates used in concrete production involves using external conveying equipment to feed the concrete aggregates into the interior of the fixed shell from the upper left side of the device. The aggregates fall through the left side of the inner plate and into its interior. The drive mechanism is then activated, causing a rotating rod to rotate. The conveying blades on the rotating rod move the concrete aggregates to the right. Simultaneously, water is fed into the device through the left end of a water pipe, which then flows out through the lower side of the pipe to rinse the aggregates. As the conveying blades move the aggregates to the right, the friction between the aggregate particles and the continuous rinsing by the water flow remove sand adhering to the surface of the aggregates. The fallen sand is then discharged through a filter screen and a drain outlet along with the water flow.

[0013] Furthermore, during the transportation and cleaning of aggregates, activating the anti-adhesion mechanism will cause the filter screen to vibrate up and down, shaking off the suspended matter adhering to the surface of the aggregate particles. At the same time, air bubbles are sprayed upward from the exhaust pipe, which can reduce the amount of suspended matter adhering to the surface of the aggregates and cause the water flow to surge and remove the aggregates.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are: the present invention, by setting up an inner plate, conveying blades, filter screen, water pipe and other structures, makes the aggregate rubbed and washed during movement, thereby removing the adhering substances on the surface of the aggregate;

[0015] By setting up a filter screen that can move up and down and a lifting rod, the filter screen vibrates the aggregate during washing, thereby reducing the possibility of suspended matter adhering to the surface of the aggregate.

[0016] By setting up an exhaust mechanism, bubbles will rapidly rise in the water flow during the washing process of aggregates, which will then carry suspended matter away from the surface of aggregates, reducing the amount of suspended matter adhering to the surface of aggregates.

[0017] By incorporating a toggle mechanism, this device can quickly remove internal moisture from aggregates during transport, thereby reducing the amount of suspended solids adhering to the aggregate surface. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1-6This invention provides a technical solution: a concrete aggregate cleaning device and its cleaning method, comprising a mounting frame 1, a fixed shell 2 fixedly connected to the upper side of the mounting frame 1, the left side height of the fixed shell 2 being less than the right side height of the fixed shell 2, a drain outlet 3 opened on the left side of the fixed shell 2, a water pipe bracket 4 fixedly connected to the left side of the fixed shell 2, a water pipe 5 fixedly connected to the upper side of the water pipe bracket 4, a drain outlet opened on the lower side of the water pipe 5, the right end of the water pipe 5 extending to the upper middle part of the fixed shell 2, the drain outlet 3 connecting the left side of the fixed shell 2 to the interior of the fixed shell 2, an inner plate 6 fixedly connected to the upper side of the inner wall of the fixed shell 2, the lower side of the inner plate 6 not connected to the outer wall of the fixed shell 2. The inner plate 6 has an installation port on its left side, and a filter screen 7 is installed inside the installation port. The left side of the filter screen 7 contacts the inner wall of the fixed shell 2. A transmission mechanism 8 is fixedly connected to the right side of the mounting frame 1. A rotating rod 9 is fixedly connected to the output end of the transmission mechanism 8. The left end of the rotating rod 9 is rotatably connected to the left side of the inner wall of the fixed shell 2 through a bearing. Several conveying blades 10 are fixedly connected to the outer wall of the rotating rod 9. A strip-shaped opening 12 is opened on the right side of the middle part of the inner plate 6. The strip-shaped opening 12 connects to the upper side of the inner plate 6. The left side of the inner wall of the strip-shaped opening 12 and the right side of the inner wall of the strip-shaped opening 12 are inclined to the left and right sides respectively. An anti-adhesion mechanism 11 is also provided on the upper surface of the mounting frame 1.

[0028] When in use, the aggregate is put into the inner plate 6 from the upper left side, and water is introduced into the water pipe 5 so that the water is evenly discharged from the lower side of the water pipe 5. Then, the transmission machine 8 is started, which drives the rotating rod 9 to rotate. In turn, the rotating rod 9 drives the conveying blade 10 to rotate, which drives the aggregate particles to the right side of the inner plate 6. When the conveying blade 10 drives the aggregate to tumble, the aggregate rubs against each other, which will cause the impurities on its surface to fall off. Then, it is discharged through the water flow through the filter screen 7 and the drain outlet 3. The cleaned aggregate is output from the right side of the inner plate 6.

[0029] The anti-adhesion mechanism 11 includes a fixing block 101. The outer wall of the fixing block 101 is fixedly connected to the outer wall of the mounting frame 1. A motor 102 is fixedly connected to the inner wall of the fixing block 101. A rotating plate 103 is fixedly connected to the output end of the motor 102. A hinge rod 104 is rotatably connected to the outer wall of the rotating plate 103 via a bearing. A lifting rod 105 is hinged to the other end of the hinge rod 104. The upper end of the lifting rod 105 penetrates the fixing shell 2 and extends to the upper side of the fixing shell 2 and the lower surface of the filter screen 7. The filter screen 7 is hinged, and the outer wall of the filter screen 7 contacts the inner wall of the mounting port. A toggle mechanism 107 is provided on the lower right side of the inner plate 6, and an exhaust mechanism 106 is provided on the left side of the rotating plate 103. The connection between the hinge rod 104 and the rotating plate 103 is not at the center of the rotating plate 103. When the rotating plate 103 rotates, the hinge rod 104 and the lifting rod 105 can be dragged up and down. The outer wall of the lifting rod 105 that penetrates the fixed shell 2 contacts the inner wall of the fixed shell 2. The lower surface edge of the filter screen 7 protrudes downward.

[0030] While rinsing the aggregate, the motor 102 is started, which drives the rotating plate 103 to rotate. Since the connection between the rotating plate 103 and the hinge rod 104 is not the center of the rotating plate 103, the rotating plate 103 will drive the hinge rod 104 to drag the lifting rod 105 up and down. This will cause the lifting rod 105 to drive the filter screen 7 to shake up and down slightly, causing the filter screen 7 to vibrate the aggregate on its upper side, thereby shaking off impurities on the surface of the aggregate and reducing the adhesion of suspended matter on the surface of the aggregate.

[0031] The exhaust mechanism 106 includes a first pressure plate 601. The lower surface of the first pressure plate 601 is slidably connected to the outer wall of the mounting bracket 1, and the outer wall of the first pressure plate 601 contacts the outer wall of the hinge rod 104. An airbag 602 is fixedly connected to the side of the outer wall of the first pressure plate 601 away from the hinge rod 104, and a second pressure plate 603 is fixedly connected to the other side of the airbag 602. A one-way valve is provided on the second pressure plate 603, with the input side of the one-way valve being the side away from the airbag 602. A first spring 604 is fixedly connected to the side of the outer wall of the second pressure plate 603 near the first pressure plate 601, and the other end of the first spring 604 is fixedly connected to the outer wall of the first pressure plate 601. Spring 604 is located inside airbag 602, and main air pipe 605 is fixedly connected to the side of second pressure plate 603 away from first pressure plate 601. Auxiliary air pipe 606 is fixedly connected to the upper end of main air pipe 605. One side of auxiliary air pipe 606 extends to the lower side of filter screen 7, and exhaust pipe 607 is fixedly connected to the upper side of auxiliary air pipe 606. The upper end of exhaust pipe 607 passes through filter screen 7 and communicates with the upper side of filter screen 7. Waterproof one-way valve 608 is fixedly connected to the upper side of inner wall of exhaust pipe 607. The interior of exhaust pipe 607 is connected to the interior of airbag 602 through auxiliary air pipe 606 and main air pipe 605, and the output side of waterproof one-way valve 608 is the upper side.

[0032] While the hinge rod 104 drags the lifting rod 105 up and down, the lower end of the hinge rod 104 moves left and right due to the dragging of the rotating plate 103. This causes the hinge rod 104 to repeatedly apply pressure to the first pressure plate 601. When the first pressure plate 601 is pushed by the lower end of the hinge rod 104, it squeezes the motor 102, causing the hinge rod 104 to contract. This causes the gas inside the motor 102 to be quickly ejected through the lifting rod 105 and the exhaust mechanisms 106 and 108, forming upward-rushing bubbles in the water flow. This washes away the suspended matter on the surface of the aggregate, facilitating the removal of the suspended matter. When the hinge rod 104 moves away from the first pressure plate 601, the elastic force of the first spring 604 supports the first pressure plate 601 to return to its original position. At this time, the airbag 602 draws gas through the one-way valve on the second pressure plate 603, causing the airbag 602 to re-inflate.

[0033] The actuating mechanism 107 includes a first inclined block 701, the outer wall of which is fixedly connected to the lower right surface of the filter screen 7. A second inclined block 702 is in contact with the lower side of the first inclined block 701, and the lower surface of the second inclined block 702 is slidably connected to the outer wall of the fixed shell 2. The upper surface of the second inclined block 702 is in contact with the lower side of the outer wall of the inner plate 6. A lever 703 is fixedly connected to the upper surface of the second inclined block 702. The upper side of the lever 703 passes through the strip-shaped opening 12 and extends to the upper side of the inner plate 6. A second spring is fixedly connected to the right end of the second inclined block 702. 704, a stop block 705 is fixedly connected to the right side of the second spring 704, and the lower side of the stop block 705 is fixedly connected to the outer wall of the inner plate 6. An inclined conveying blade is provided on the upper part of the conveying blade 10, and two rotating rods 9 are provided. The conveying blades of the conveying blade 10 on the two rotating rods 9 are arranged alternately. The toggle block 703 is located between the conveying blades 10 on both sides. The outer wall of the second inclined block 702 and the outer wall of the first inclined block 701 are inclined on the side that are close to each other. When the filter screen 7 descends, it can be moved by pushing the second inclined block 702 through the first inclined block 701.

[0034] As the filter screen 7 moves up and down to vibrate the aggregate, it causes the first inclined block 701 to move up and down continuously. This in turn causes the first inclined block 701 to push the second inclined block 702 to move back and forth. The second inclined block 702 then drives the pusher block 703 to push the aggregate moving upward, allowing the water mixed inside the aggregate to leave more quickly and reducing the amount of suspended matter in the water that re-adheres to the surface of the aggregate.

[0035] A method for cleaning aggregates used in concrete production involves using an external conveying device to feed the concrete aggregates into the interior of the fixed shell 2 from the upper left side of the device. The concrete aggregates fall into the interior of the inner plate 6 from the left side. Then, the drive motor 8 is activated, causing the rotating rod 9 to rotate. The conveying blades 10 on the rotating rod 9 move the concrete aggregates to the right. Simultaneously, water is input through the left end of the water pipe 5 and discharged through the lower side of the water pipe 5 to rinse the concrete aggregates. During the process of the conveying blades 10 transporting the aggregates to the right, the aggregate particles rub against each other, and the water discharged from the water pipe 5 continuously rinses the aggregates, removing the sand adhering to the surface of the concrete aggregates. The fallen sand is then discharged through the filter screen 7 and the drain outlet 3 along with the water flow.

[0036] Furthermore, during the transportation and cleaning of aggregates, activating the anti-adhesion mechanism 11 will cause the filter screen 7 to vibrate up and down, causing the suspended matter adhering to the surface of the aggregate particles to be shaken off. At the same time, air bubbles are sprayed upward from the exhaust pipe 607, which can reduce the amount of suspended matter adhering to the surface of the aggregates and cause the water flow to surge and remove the aggregates.
