Detailed Implementation

[0040] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0041] like Figures 1 to 4 As shown in the figure, an embodiment of the present invention provides a device for separating concrete of different grades, comprising:

[0042] Separator 1;

[0043] The material feeding plate 11 is fixed inside the partition box 1, and the bottom end of the material feeding plate 11 has multiple holes.

[0044] The limiting plate 12 is fixedly connected to the top middle part of the above-mentioned feeding plate 11;

[0045] Magnetic plate 13 is inserted into the interior of the aforementioned limiting plate 12 and the partition box 1, and multiple magnetic plates 13 are provided.

[0046] A limiting component is disposed inside the limiting plate 12 and is used to fix the magnetic plate 13.

[0047] A sealing assembly is installed at the bottom of the discharge plate 11 and is used to seal the discharge plate 11. In a specific embodiment of this invention, during nuclear power plant construction, concrete of different grades is placed inside a partition box 1, and multiple magnetic plates 13 are inserted between a limiting plate 12 and the partition box 1. A limiting assembly is used to limit the multiple magnetic plates 13, which can separate concrete of various grades. The sealing assembly seals multiple holes at the bottom of the discharge plate 11. When a certain grade of concrete is needed, the sealing assembly can open the holes and lower the concrete for use, reducing construction obstacles caused by the accumulation of multiple concrete storage containers. It also facilitates the selection of different grades of concrete. Furthermore, when a large quantity of a certain grade of concrete is used, the spacing of some magnetic plates 13 can be eliminated to increase the storage capacity of a single grade of concrete.

[0048] The aforementioned limiting assembly includes a first magnetic block 2, a first elastic element 21, and a second magnetic block 22. The first magnetic block 2 is slidably connected inside the limiting plate 12. The first elastic element 21 is fixed to the outside of the first magnetic block 2, with one end of the first elastic element 21 away from the first magnetic block 2 fixed to the first magnetic block 2. The second magnetic block 22 is fixed inside the limiting plate 12. The second magnetic block 22 can be magnetically attracted to both the magnetic plate 13 and the first magnetic block 2. When the magnetic plate 13 is limited, the magnetic plate 13 is inserted into the limiting plate 12. Inside the magnetic plate 13, the first magnetic block 2 is squeezed and slid into the limiting plate 12. The first elastic element 21 contracts and is subjected to force. When the round hole of the magnetic plate 13 corresponds to the first magnetic block 2, the first elastic element 21 springs back to press the first magnetic block 2, and the first magnetic block 2 is inserted into the corresponding round hole of the magnetic plate 13, which has the effect of limiting the magnetic plate 13. In addition, the second magnetic block 22 can magnetically attract the magnetic plate 13 and the first magnetic block 2. With the help of the multiple limiting components set inside the limiting plate 12, the limiting effect of the magnetic plate 13 is improved.

[0049] like Figures 1 to 3 As shown, the sealing assembly includes a rotating motor and a blocking plate 3; the rotating motor is fixed inside the limiting plate 12; the blocking plate 3 is fixed outside the output end of the rotating motor, and the output end of the rotating motor passes through the feeding plate 11; when sealing concrete of different grades stored inside the partition box 1, the rotating motor drives the blocking plate 3 to rotate, and the blocking plate 3 can block the hole opened at the bottom of the feeding plate 11. When discharging concrete, the rotating motor drives the blocking plate 3 to rotate quickly, opening the concrete discharge hole, thereby controlling the discharge of a single type of concrete.

[0050] like Figures 1 to 3 , Figure 5 As shown, a flow guide box 4 is fixedly connected to the bottom end of the aforementioned partition box 1; a material cylinder is fixedly connected to the bottom end of the aforementioned flow guide box 4; when precise material feeding is required in a certain area during nuclear power engineering, the flow guide box 4 installed at the bottom end of the partition box 1 is used to guide the concrete during feeding. The concrete is fed from the holes of the feeding plate 11 into the interior of the flow guide box 4, and finally precisely fed by the small-mouth material cylinder at the bottom end of the flow guide box 4, thereby improving the accuracy of concrete feeding.

[0051] A support frame 5 is fixedly connected inside the aforementioned flow guide box 4; a servo motor 51 is fixedly connected inside the aforementioned support frame 5; a connecting rod 52 is fixedly connected to the bottom end of the aforementioned servo motor 51, and the connecting rod 52 is located inside the material cylinder; an agitator 53 is fixedly connected to the outside of the aforementioned connecting rod 52, and multiple agitator 53s are provided; when some concrete is inside the partition box 1, after a long period of time, some of the moisture evaporates and the concrete hardens slightly, the concrete becomes more viscous. By using the support frame 5 fixed inside the flow guide box 4, the servo motor 51 is protected inside. The output end of the servo motor 51 rotates, driving multiple agitator 53s on the connecting rod 52 to agitate the discharged concrete, thereby improving the discharge effect of the concrete and reducing the degree of hardening of the concrete.

[0052] The aforementioned flow guide box 4 has a water storage chamber 6 inside; an electrically controlled nozzle is fixedly connected inside the aforementioned flow guide box 4 and is connected to the water storage chamber 6; a plug 61 is installed on the outside of the aforementioned flow guide box 4, and multiple plugs 61 are provided; when concrete is stored for a long time and some moisture evaporates due to hot weather, and the concrete is in a viscous state before being poured, multiple plugs 61 are first opened, and water is injected into the water storage chamber 6 inside the flow guide box 4 from different areas. During the concrete pouring process, a small amount of water is sprayed out from the electrically controlled nozzle, thereby mixing with the poured concrete, and the viscosity of the concrete is reduced by stirring by multiple stirring blades 53.

[0053] A shielding block 7 is fixedly attached to the flow guide box 4 near the electronically controlled nozzle. The shielding block 7 is hollow inside and has spray holes near the electronically controlled nozzle. When concrete is poured into the flow guide box 4, some concrete will adhere to the electronically controlled nozzle, causing blockage. The shielding block 7 is fixed to the electronically controlled nozzle to block it, so that the electronically controlled nozzle is located in the hollow part of the shielding block 7, reducing the amount of concrete adhering to the electronically controlled nozzle. In addition, the spray holes on the shielding block 7 face downwards, which facilitates the use of the electronically controlled nozzle for water spraying.

[0054] The aforementioned flow guide box 4 has a partition 8 fixedly connected inside; a second solenoid valve 81 is fixedly connected to the outside of the aforementioned partition 8; the aforementioned partition 8 and the second solenoid valve 81 can divide the water storage chamber 6 into two slots; when concrete is poured, concrete of different viscosity requires different amounts of water to be added. The partition 8 and the second solenoid valve 81 are fixed at the water storage chamber 6 to separate the two slots. The slot above the partition 8 is used for normal water storage, and the slot below the partition 8 is used for temporary storage of a small amount of water. According to the different viscosity of the concrete, different amounts of water are released through the second solenoid valve 81, thus making it suitable for pouring concrete of different viscosity.

[0055] like Figures 1 to 3 , Figure 5 , Figure 6As shown, a trigger rod 9 is slidably connected inside the connecting rod 52; a second elastic element 91 is fixedly connected to the outside of the trigger rod 9, and the end of the second elastic element 91 away from the trigger rod 9 is fixedly connected to the connecting rod 52; a sensor 92 is installed at the bottom of the connecting rod 52 and is electrically connected to the electronically controlled nozzle; when the connecting rod 52 rotates, the second elastic element 91 is stretched by the centrifugal force of the rotating connecting rod 52, causing the trigger rod 9 to slide down into the connecting rod 52. As the connecting rod 52 rotates continuously, it also squeezes the trigger sensor 92. The sensor 92 sends a signal to the electronically controlled nozzle, and the electronically controlled nozzle starts spraying water. When the connecting rod 52 stops rotating, the second elastic element 91 pulls the trigger rod 9 back to its original position, which can control the water spraying of the electronically controlled nozzle.

[0056] like Figures 1 to 3 , Figure 5 , Figure 7 As shown, an atomizing nozzle 10 is installed on the outside of the aforementioned guide box 4; a water distribution pipe is fixedly connected inside the aforementioned atomizing nozzle 10; the aforementioned water distribution pipe has two output ends, and one output end of the water distribution pipe is connected to the atomizing nozzle 10; a water pump is fixedly connected to the end of the aforementioned water distribution pipe away from the atomizing nozzle 10, and a filter ball 101 is sleeved on the outside of the water pump; multiple overflow holes 102 are opened on the inner wall of the top of the aforementioned partition box 1, and the multiple overflow holes 102 are connected to the other output end of the water distribution pipe; a sliding arc block 103 is slidably connected inside the aforementioned feed plate 11 by a spring, and a groove corresponding to the sliding arc block 103 is opened at the top of the blocking plate 3; a trigger 104 is installed inside the aforementioned feed plate 11 near the sliding arc block 103, and the trigger 104 is connected to the water... Pump electrical connection; When concrete is poured, it easily adheres to the inner wall of the guide box 4. The blocking plate 3 rotates first to squeeze the sliding arc block 103. The sliding arc block 103 squeezes the spring to contract and squeezes the trigger 104. The trigger 104 sends a signal to the water pump, and the water pump draws water into the diversion pipe. The filter ball 101 filters the water around the water pump and sends some water to the atomizing nozzle 10 for spraying. This pre-wets the inner wall of the guide box 4, lubricates it when the concrete flows down into the inner wall of the guide box 4, and reduces the adhesion of concrete to the inner wall of the guide box 4. At the same time, some water overflows to the overflow hole 102 and flows to the inner wall of the partition box 1, wetting and cleaning the inner wall of the partition box 1, reducing the adhesion of concrete to the inner wall of the partition box 1, and reducing the difficulty of cleaning the hardened concrete.

[0057] like Figure 8 As shown, a construction method for separating concrete of different grades is described. This method uses the aforementioned device for separating concrete of different grades and the steps are as follows:

[0058] S1: First, insert multiple magnetic plates 13 into the interior of the partition box 1 and place them between the partition box 1 and the limiting plate 12. The second magnetic block 22 magnetically attracts and limits the magnetic plates 13 and the first magnetic block 2. The rotating motor drives the blocking plate 3 to rotate and block the hole of the material feeding plate 11. Then, concrete of different grades is poured into different partition troughs for storage.

[0059] S2: Then, when different grades of concrete are being poured, a hole at the bottom of the pouring plate 11 is opened, and the concrete is poured through the guide box 4. Then, the output end of the servo motor 51 rotates, driving the stirring blade 53 on the connecting rod 52 to stir the poured concrete.

[0060] S3: Water is then injected into the water storage chamber 6, and the overflow water from the second solenoid valve 81 flows to the electronically controlled nozzle. The trigger rod 9 slides to trigger the sensor 92, and the electronically controlled nozzle sprays water into the inside of the guide box 4. After the concrete and water are mixed, they flow down, and finally, multiple agitators 53 agitate and discharge the mixed concrete.

[0061] In the working process of nuclear power engineering construction, concrete of different grades is placed inside the partition box 1, and multiple magnetic plates 13 are inserted between the limiting plate 12 and the partition box 1. A limiting component is used to limit the magnetic plates 13, which can separate concrete of various grades. A sealing component seals multiple holes at the bottom of the discharge plate 11. When a certain grade of concrete is needed, the sealing component can be used to open the holes and discharge the concrete, reducing construction obstacles caused by the accumulation of multiple concrete storage containers. It also facilitates the selection of different grades of concrete. Furthermore, when a large quantity of a certain grade of concrete is needed, the spacing of some magnetic plates 13 can be eliminated to increase the storage capacity of that single grade of concrete. When the magnetic plates 13 are limited, they are inserted into the limiting plate 12. 3. The first magnetic block 2 is squeezed and slid into the limiting plate 12. The first elastic element 21 contracts and is subjected to force. When the round hole of the magnetic plate 13 corresponds to the first magnetic block 2, the first elastic element 21 springs back to squeeze the first magnetic block 2, and the first magnetic block 2 is inserted into the corresponding round hole of the magnetic plate 13, which has the effect of limiting the magnetic plate 13. The second magnetic block 22 can magnetically attract the magnetic plate 13 and the first magnetic block 2. With the help of the multiple limiting components set inside the limiting plate 12, the limiting effect of the magnetic plate 13 is improved. When sealing concrete of different grades stored in the partition box 1, the rotating motor drives the blocking plate 3 to rotate. The blocking plate 3 can seal the hole opened at the bottom of the feeding plate 11. When the concrete is fed, the rotating motor drives the blocking plate 3 to rotate quickly and open the concrete feeding hole, thereby controlling the feeding of a single type of concrete.

[0062] When precise material feeding is required in a certain area during nuclear power engineering, the flow guide box 4 installed at the bottom of the partition box 1 is used to guide the concrete during feeding. The concrete is fed from the holes of the feeding plate 11 into the interior of the flow guide box 4, and finally precisely fed through the small-mouth material cylinder at the bottom of the flow guide box 4, thereby improving the accuracy of concrete feeding. When some concrete slightly hardens inside the partition box 1, the concrete is more viscous. The support frame 5 is fixed inside the flow guide box 4 to protect the servo motor 51. The output end of the servo motor 51 rotates, driving multiple stirring blades 53 on the connecting rod 52 to stir the fed concrete, thereby improving the concrete feeding effect and reducing the degree of concrete hardening.

[0063] When the concrete is in a viscous state during pouring, multiple plugs 61 are first opened, and water is injected into the water storage chambers 6 inside the flow box 4 from different areas. During the pouring process, water is sprayed from the electrically controlled nozzles, mixing with the poured concrete. Multiple agitators 53 further agitate the concrete, reducing its viscosity. As the concrete flows into the flow box 4, some concrete adheres to the electrically controlled nozzles, potentially causing blockages. A shielding block 7 is used to block these blockages, placing the nozzles within the hollow space of the shielding block 7 to reduce concrete adhesion. The nozzle holes on the shielding block 7 face downwards for easy water spraying. Different viscosity levels of concrete require different amounts of water during pouring. Different water volumes are separated by a partition 8 and a second solenoid valve 81 fixed at the water storage chamber 6. The groove above the partition 8 is used for normal water storage, while the groove below the partition 8 is used for temporary storage of small amounts of water. Depending on the viscosity of the concrete, different amounts of water are released through the second solenoid valve 81, thus making it suitable for concrete of different viscosity. When the connecting rod 52 rotates, the centrifugal force of the rotating connecting rod 52 stretches the second elastic element 91, causing the trigger rod 9 to slide down into the connecting rod 52. As the connecting rod 52 continues to rotate, it also squeezes the trigger sensor 92. The sensor 92 sends a signal to the electronically controlled nozzle, and the electronically controlled nozzle starts spraying water. When the connecting rod 52 stops rotating, the second elastic element 91 pulls the trigger rod 9 to reset, which can control the water spraying of the electronically controlled nozzle.

[0064] When concrete is poured, it tends to adhere to the inner wall of the flow box 4. The blocking plate 3 rotates first to compress the sliding arc block 103. The sliding arc block 103 compresses the spring and compresses the trigger 104. The trigger 104 sends a signal to the water pump, which pumps water into the diversion pipe. The filter ball 101 filters the water around the pump and sends some water to the atomizing nozzle 10 for spraying. This pre-wets the inner wall of the flow box 4, lubricating it as the concrete flows down and reducing its adhesion to the inner wall. At the same time, some water overflows from the overflow hole 102 and flows to the inner wall of the partition box 1, wetting and cleaning the inner wall of the partition box 1 and reducing concrete adhesion. This also reduces the difficulty of cleaning hardened, adhered concrete.
