Description

Technical Field

[0001] This invention relates to the field of slag composite technology, and in particular to a slag composite powder composite device with double-acting stirring. Background Technology

[0002] Cement concrete is the most consumed and widely used material in human life and survival. Current research both domestically and internationally has proven that using slag, steel slag powder, and other materials as admixtures in cement concrete, under proper conditions, can not only provide the significant environmental benefits mentioned above, but also specifically improve various properties of pure cement concrete, including workability, durability, and strength development. For example, using finely ground slag powder as an admixture in concrete production can significantly improve the concrete's corrosion resistance, prevent shrinkage and cracking, and result in faster early strength growth than pure cement concrete. The significant reduction in heat of hydration leads to a decrease in temperature stress in the concrete masonry, effectively ensuring the quality of large-volume concrete.

[0003] In traditional composite equipment, the two types of slag powder are poured into the equipment in batches and then stirred and mixed by a stirring device. This causes some of the slag powder to settle at the bottom of the composite tank and is difficult to turn up during the stirring process, which reduces the mixing effect. In addition, the ratio of the two powders is difficult to control, affecting the mixing quality. Therefore, we propose a slag composite powder composite equipment with dual-action stirring and controllable ratio to solve the above problems. Summary of the Invention

[0004] The present invention proposes a double-acting stirring slag composite powder compounding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A double-acting stirring slag composite powder compounding device includes a mounting frame, a compounding tank, a stirring mechanism, and a rotating mechanism. A fixed block is installed on the outside of the compounding tank, and rotating mechanisms for rotating the fixed block are installed on both sides of the fixed block. A stirring mechanism for mixing and compounding slag composite powder and steelmaking casting residue powder is provided inside the compounding tank. Both the stirring mechanism and the rotating mechanism are electrically controlled gear-driven rotating structures. The stirring mechanism, rotating mechanism, and compounding tank are used in conjunction. Two storage tanks are provided above the compounding tank, and the two storage tanks are used to store slag composite powder and steelmaking casting residue powder, respectively.

[0007] Preferably, the stirring mechanism includes a motor, one end of which is provided with two gears, which are meshed together. One gear is connected to the motor, and a mounting plate is installed below the other gear. Spiral rods are respectively provided below both ends of the mounting plate, and a stirring rod is provided between the two spiral rods.

[0008] Preferably, the motor and the two gears are both located above the composite barrel, and the mounting plate is located inside the composite barrel.

[0009] Preferably, a second motor is installed at the upper end of each of the two helical rods, and the two second motors are respectively installed inside the two ends of the mounting plate.

[0010] Preferably, the two spiral auxiliary rods are arranged symmetrically at an inclination, and the rod-shaped part on the stirring rod becomes shorter as the diameter of the composite tank decreases.

[0011] Preferably, the rotating mechanism includes a motor three, a gear two is installed at the output end of the motor three, a gear three is meshed above the gear two, a connecting rod is installed on one side of the gear three, and the connecting rod is connected to the fixed block.

[0012] Preferably, the motor, gear 2, and gear 3 are all mounted in the mounting bracket.

[0013] Preferably, the composite barrel has an inlet at the top and an outlet at the bottom, and a valve, which is a butterfly valve, is installed on the outlet.

[0014] Preferably, valve two is installed on the feed inlet and on each of the two storage tanks, and a solid dust flow meter is installed above valve two on the storage tank.

[0015] Preferably, the storage container is provided with a transparent observation window, and the outside of the observation window is provided with a scale.

[0016] A method for compounding slag composite powder based on the above-mentioned composite device, characterized in that it includes the following:

[0017] Slag composite powder and steelmaking casting residue powder are poured into two storage tanks respectively. Three valves are opened, allowing the slag composite powder and steelmaking casting residue powder from the two storage tanks to fall onto the feed inlet and into the composite tank. Two solid dust flow meters are used to detect the flow rate of each type of slag powder. When the required amount is reached, two valves are closed. After all the slag powder in the feed inlet has fallen into the composite tank, valve two at the feed inlet is closed. Motor one drives one gear one to rotate, which in turn drives another gear one and the mounting plate to rotate, causing the stirring rod and two screw rods to rotate. Simultaneously, two motors control the two screw rods to rotate during the rotation, stirring and compounding the slag powder in the composite tank. Motor three drives gear two to rotate, which in turn drives gear three and the composite tank to rotate and tilt, ensuring that some of the slag powder accumulated at the bottom of the composite tank is fully stirred. After stirring, the composite tank is reset, and valve one is opened to discharge the composite slag powder.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. This device, through a set of motor one, gear one, mounting plate, motor two, stirring rod, and screw rod, is used to stir and mix the slag powder in the composite barrel to form composite powder. By using it in conjunction with the rotating mechanism while stirring, the composite barrel is rotated and tilted, and the slag powder at the bottom of the composite barrel is stirred at the same time, so as to improve the mixing effect of the slag powder.

[0020] 2. The device uses a solid dust flow meter to detect and control the amount of slag powder output from the storage tank to achieve quantitative control. The observation window allows for easy observation of the remaining amount of slag powder inside the storage tank, facilitating timely replenishment.

[0021] In summary, this device can not only fully stir the slag powder at the bottom of the composite tank, improving the mixing effect, but also quantitatively feed the slag powder and facilitate the observation of the remaining amount of slag powder inside the storage tank, making it convenient to add more in a timely manner, thus demonstrating high practicality.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] Reference Figure 1 and Figure 2 As shown, this embodiment provides a double-acting stirring slag composite powder compounding device, including a mounting frame 1, a compounding tank 2, a stirring mechanism 3, and a rotating mechanism 5. A fixing block 4 is installed on the outside of the compounding tank 2, and a rotating mechanism 5 is installed on both sides of the fixing block 4 for rotating it. The compounding tank 2 is provided with a stirring mechanism 3 for stirring and compounding slag composite powder and steelmaking casting residue powder. Both the stirring mechanism 3 and the rotating mechanism 5 are electrically controlled gear transmission rotating structures. The stirring mechanism 3, the rotating mechanism 5, and the compounding tank 2 are used in conjunction. Two storage tanks 10 are provided on the top of the compounding tank 2. The two storage tanks 10 are used to store slag composite powder and steelmaking casting residue powder, respectively. A transparent observation window 12 is provided on the storage tank 10, and a scale is provided on the outside of the observation window 12 to facilitate observation of the remaining amount in the storage tank 10, so as to add it in time.

[0028] like Figures 1-3 As shown, the stirring mechanism 3 includes a motor 301. Two gears 302 are provided at one end of the motor 301. The two gears 302 are meshed and connected. One gear 302 is connected to the motor 301. An installation plate 303 is installed below the other gear 302. The motor 301 and the two gears 302 are all located above the composite tank 2. The installation plate 303 is located inside the composite tank 2. Spiral auxiliary rods 306 are respectively provided below both ends of the installation plate 303. The two spiral auxiliary rods 306 are symmetrically inclined. Motors 305 are respectively installed at the upper ends of the two spiral auxiliary rods 306. The two motors 305 are respectively installed inside both ends of the installation plate 303. A stirring rod 304 is provided between the two spiral auxiliary rods 306. The rod-shaped part on the stirring rod 304 becomes shorter as the diameter of the composite tank 2 decreases, and is used to stir and mix the slag powder in the composite tank 2.

[0029] like Figure 1 and Figure 2As shown, the rotating mechanism 5 includes a motor 501, a gear 502 is installed at the output end of the motor 501, a gear 503 is meshed above the gear 502, a connecting rod 504 is installed on one side of the gear 503, and the connecting rod 504 is connected to the fixed block 4. The motor 501, gear 502 and gear 503 are all installed in the mounting frame 1 to control the compound barrel 2 to rotate and tilt in a reciprocating arc shape. They are arranged on the left and right sides respectively and are used in conjunction with the stirring mechanism 3 to improve the mixing effect.

[0030] like Figure 1 and Figure 2 As shown, a feed inlet 6 is provided above the composite tank 2 for collecting slag powder, and a discharge outlet 7 is provided below the composite tank 2. A valve 8 is installed on the discharge outlet 7 to control the discharge. The valve 8 is a butterfly valve. A valve 9 is installed on the feed inlet 6 and the two storage tanks 10 to control the feeding. A solid dust flow meter 11 is installed above the valve 9 on the storage tank 10 to calculate the amount of slag powder, so as to accurately control the amount of the two types of slag powder.

[0031] The working principle of this invention (which is also its basic mixing method) is as follows: When using the device, slag composite powder and steelmaking casting residue powder are poured into two storage tanks 10, with the steelmaking casting residue powder accounting for 10% to 20% of the total amount. When compounding is required, three valves 29 are opened, allowing the slag composite powder and steelmaking casting residue powder in the two storage tanks 10 to fall onto the feed inlet 6 and into the compounding tank 2. Two solid dust flow meters 11 detect the flow rates of the two types of slag powder. When the required amount is reached, the two valves 29 are closed. After all the slag powder in the feed inlet 6 has fallen into the compounding tank 2, the valves 29 on the feed inlet 6 are closed. 9. Motor 301 drives one gear 302 to rotate, which in turn drives the other gear 302 and the mounting plate 303 to rotate, which in turn drives the stirring rod 304 and the two spiral auxiliary rods 306 to rotate. At the same time, two motors 305 control the two spiral auxiliary rods 306 to rotate during the rotation, which stirs and combines the slag powder in the composite tank 2. Motor 501 drives gear 502 to rotate, which in turn drives gear 503 and the composite tank 2 to rotate and tilt, so that some of the slag powder accumulated at the bottom of the composite tank 2 is fully stirred. After the stirring is completed, the composite tank 2 is reset and valve 8 is opened to discharge the composite slag powder.

[0032] In the above mixture, the amount of cast slag powder added is 10% to 20%, and the indicators of the cast slag powder mixture formed after mixing are shown in the table below.

[0033] Table 1 Technical Requirements

[0034]

[0035] The addition of 10% to 20% foundry slag powder still does not fall below the S95 grade index of slag powder. Previously, simple mixing only allowed for the addition of 5% foundry slag powder to form a composite powder. The above mixing method allows for further utilization of the foundry slag powder while ensuring the quality of the mixed powder.

[0036] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
