[0004] In the above patent, the raw material enters the interior through the feed port, and then is thrown to the impact plate through the rotation of the hammer assembly, and is crushed by the rebound. Since the impact plate is fixed or must be connected with a corresponding elastic component, after being hit, the elastic potential energy shrinks and rebounds again to be crushed. However, the above methods are all passive counterattacks and cannot further provide a crushing effect. Summary of the invention

The rotation of the crown gear 2 causes the connected crankshaft to rotate, and the crankshaft pushes the first impact plate to swing through the connecting rod to assist in crushing the material. At the same time, the crown gear 1 connected to one end of the crankshaft drives the piston plate to perform telescopic movement in the pressurized cylinder, compressing the air and sending it into the air storage cylinder.

[0039] A cement raw material crushing device and a cement production method based on high-sulfur fly ash retarding according to an embodiment of the present application are described below with reference to the accompanying drawings.

[0040] like Figure 1-Figure 2It is shown that a cement raw material crushing device according to an embodiment of the present application mainly includes a crusher base 1, and the crusher base 1 is designed as a structure with openings at both ends. An impact box 11 is installed at the top opening of the crusher base 1 to accommodate and guide the material for crushing. A feed port 12 is provided on one side of the impact box 11. The design of this opening allows the raw material to be crushed to enter the impact box 11 smoothly. Inside the impact box 11, a rotating shaft 2 that can rotate at high speed is installed, and a plurality of plate hammers 21 are evenly distributed on the outer peripheral surface of the rotating shaft 2. When the rotating shaft 2 rotates at high speed, these plate hammers 21 will hit the raw materials entering the impact box 11 at high speed, thereby generating a strong impact force on the raw materials, so that they can be quickly crushed.

[0041] In order to further improve the crushing effect, the first counterattack plate 13, the second counterattack plate 14 and the third counterattack plate 15 are sequentially arranged on one side of the inner wall of the counterattack box 11 from top to bottom. When the raw material enters the counterattack box 11, it is first impacted by the high-speed rotating hammer 21, which is a step for preliminary crushing of the raw material. Subsequently, the preliminary crushed raw material will be forced to be thrown to the counterattack plates on the inner wall of the counterattack box 11, namely the first counterattack plate 13, the second counterattack plate 14 and the third counterattack plate 15. Through the multiple rebound effects of these counterattack plates, the raw material can be further crushed and refined, and finally reach the required particle size requirements.

[0042] like Figure 2-Figure 5 It is shown that in order to enhance the working efficiency of the first impact plate 13, one end thereof is hinged to the inner wall of the impact box 11, allowing the first impact plate 13 to swing. There are ears 131 on both sides of the arc-shaped back side of the first impact plate 13, and a rotatable crankshaft 3 is relatively arranged above the ears 131. The curved part of the crankshaft 3 is connected to the ears 131 through a connecting rod 132. As the crankshaft 3 rotates, the connecting rod 132 will continuously push the ears 131 to reciprocate. This reciprocating displacement of the ears 131 will cause the first impact plate 13 to continuously swing back and forth. This dynamic swing helps to improve the collision efficiency between the raw material and the impact plate, thereby further optimizing the crushing effect.

[0043] The two ends of the crankshaft 3 extend through the impact box 11 respectively. A pulley 1 31 is fixed at one end of the crankshaft 3, and a crown gear 2 33 is also provided at the same end. The crown gear 2 33 is meshed with the gear 1 161 below, and the gear 1 161 is driven by the motor 16. In addition, the output end of the motor 16 can also output power through the worm gear provided on one side of the pulley 1 31 driven by the worm. As the worm drives the worm gear, the crankshaft 3 can be rotated. When crushing operations are required, the motor 16 is started, and the motor 16 drives the gear 1 161 to rotate, thereby driving the crown gear 2 33 meshed with it to rotate. As the crown gear 2 33 rotates, the crankshaft 3 connected to it will also rotate. The rotation of the crankshaft 3 drives the first impact plate 13 to swing continuously through the connecting rod 132. Specifically, when the raw material is impacted by the counterclockwise rotating hammer 21 and thrown toward the first impact plate 13, since the first impact plate 13 continuously swings back and forth, it can actively hit the flying raw material, thereby helping to improve the crushing effect. This design enables the first impact plate 13 to participate in the crushing process more effectively.

[0044] like Figure 4-Figure 7 As shown, a rotating shaft 24 capable of rotating is provided at a relative position below the first impact plate 13 to further enhance the crushing effect. Specifically:

[0045] In order to realize the accelerated rotation function of the rotating shaft 2 4 below the first counter-attack plate 13, the rotating shaft 2 4 is arranged in parallel with the pulley 1 31, and a pulley 2 41 is installed at one end. The pulley 1 31 and the pulley 2 41 are connected by a belt 34, so that when the pulley 1 31 rotates, the pulley 2 41 can be synchronously driven to rotate together through the belt 34.

[0046] Since the diameter of the pulley 2 41 is smaller than that of the pulley 1 31, the pulley 2 41 will rotate at a higher speed when the pulley 1 31 rotates. This design utilizes the speed change principle in the belt 34 transmission, and realizes the speed change through pulleys of different diameters.

[0047] Specifically, when the motor 16 starts and drives the gear 1 161 to rotate, the first counter plate 13 starts to swing through the linkage of the crown gear 2 33 and the crankshaft 3. At the same time, the pulley 1 31 at the end of the crankshaft 3 also starts to rotate, driving the pulley 2 41 to rotate at a faster speed through the belt 34.

[0048] The outer circumference of the rotating shaft 24 is evenly distributed with positioning frames 42, and the outer circumference of the positioning frames 42 is distributed with plate hammers 21. When the raw materials are counter-rotated by the plate hammers 21, part of the raw materials will be counter-rotated upward. At the same time, as the pulley 1 31 rotates, the pulley 2 41 will rotate at a higher speed, thereby driving the rotating shaft 2 4 to accelerate clockwise rotation. As the rotating shaft 2 4 rotates faster, the plate hammers 2 421 further throw the flipped raw materials toward the first counter-rotating plate 13, thereby improving the crushing effect.

[0049] In order to achieve the dust reduction function, the other end of the rotating shaft 24 is provided with a docking port 47, through which the aqueous solution can be delivered to the interior of the rotating shaft 24. Spray holes 422 are distributed on the outer peripheral surface of the rotating shaft 24. When the rotating shaft 24 rotates at high speed, the aqueous solution inside the rotating shaft 24 will be sprayed outward through the spray holes 422 by the action of centrifugal force, thereby achieving the effect of dust reduction. It is worth noting that since the rotating shaft 24 is located above the plate hammer 1 21, its dust reduction effect is more significant, which can effectively reduce the dust generated during the crushing process and improve the working environment. This design combines the crushing and dust reduction functions, which not only improves the crushing efficiency, but also reduces the dust pollution generated during the crushing process, and helps to create a cleaner working environment.

[0050] Rotation holes 423 are respectively provided on both sides of the surface of the positioning frame 42. The two rotation holes 423 allow the rotating shaft 3 44 to pass through and realize rotation. A reciprocating screw 1 45 is provided at one end of the rotating shaft 3 44, and the paths on both sides of the surface of the reciprocating screw 1 45 are arranged in positive and negative directions. In addition, a reciprocating sleeve 43 is sleeved on the outer circumferential surface of the rotating shaft 2 4, and the reciprocating sleeve 43 also has two reciprocating holes 431 penetrating therethrough, through which the reciprocating screw 1 45 can pass. Inserts are provided on the inner annular wall of the reciprocating hole 431, and one end of these inserts extends into the specific thread path of the reciprocating screw 1 45. When the reciprocating screw 1 45 rotates, the interaction between the inserts and the thread causes the reciprocating sleeve 43 to move back and forth in the axial direction.

[0051] Steel brushes 432 are distributed on the inner ring wall of the reciprocating sleeve 43, and the free ends of these steel brushes 432 contact the outer peripheral surface of the rotating shaft 2 4. In this way, when the reciprocating sleeve 43 reciprocates, the steel brushes 432 will brush the spray holes 422 on the surface of the rotating shaft 2 4. At the same time, a gear 2 441 is provided at the end of the rotating shaft 3 44 near one end of the docking port 47. A snap ring 46 is provided on the surface of the counterattack box 11, and one end of the rotating shaft 2 4 passes through this snap ring 46 to provide support for the rotating shaft 2 4. In addition, a gear ring 461 is provided on the inner ring wall of the snap ring 46, and the gear ring 461 is meshed with the gear 2 441.

[0052] A docking pipe 451 is hinged at the opening of the docking port 47, and a water spray connection pipe 452 extends from one side of the outer peripheral surface of the docking pipe 451. By connecting the water spray connection pipe 452 to the water pipe, the aqueous solution can be introduced into the interior of the rotating shaft 24. When the raw material is crushed inside the impact box 11, the pulley 241 provided at one end of the rotating shaft 24 can be driven by the pulley 131 through the belt 34, so that the rotating shaft 24 rotates rapidly. When the rotating shaft 24 rotates at a high speed, the plate hammer 2421 installed thereon will further throw the raw material impacted by the plate hammer 121 to the first impact plate 13, thereby enhancing the crushing effect of the raw material.

[0053] At the same time, while the rotating shaft 24 rotates at high speed for crushing, the aqueous solution inside it can be thrown out by centrifugal force through the spray hole 422 on the surface of the rotating shaft 24, which is used to reduce the dust generated by the crushing process inside the impact box 11, thereby achieving the purpose of dust reduction treatment.

[0054] like Figure 4 and Figure 11-Figure 17 As shown, a crown gear 1 32 is provided at the other end of the crankshaft 3 and is opposite to the pulley 1 31. A mounting plate 9 is provided on one side of the surface of the counter-attack box 11, and a gear 5 8 provided above the mounting plate 9 is meshed with the crown gear 1 32. At the same time, a reciprocating screw 2 81 is provided from the bottom of the gear 5 8 downward through the mounting plate 9.

[0055] In addition, positioning rods 91 extend downwardly from both sides of the bottom surface of the mounting plate 9, and a piston plate 71 is arranged oppositely below the positioning rods 91. Positioning tubes 72 arranged on both sides above the piston plate 71 are inserted into the positioning rods 91 to achieve positioning.

[0056] At the same time, a reciprocating slider 77 is arranged between the two positioning tubes 72, and the reciprocating slider 77 is penetrated by the reciprocating screw rod 81. The inner ring wall of the reciprocating slider 77 is provided with an insert, and one end of the insert extends into a specific path on the surface of the reciprocating screw rod 81. When the reciprocating screw rod 81 rotates, the reciprocating slider 77 can be reciprocated in the axial direction. As the reciprocating slider 77 reciprocates, the piston plate 71 will also be displaced.

[0057] The piston plate 71 is arranged inside a pressurizing cylinder 7 with an opening at the top. A one-way valve 73 is arranged on one side of the outer peripheral surface of the pressurizing cylinder 7. Through the one-way valve 73, when the piston plate 71 moves upward, the one-way valve 73 will be opened to allow gas to enter the interior of the pressurizing cylinder 7.

[0058] An air storage cylinder 75 is also arranged parallel to and opposite to one side of the pressurizing cylinder 7. The top of the air storage cylinder 75 is connected to the bottom of the pressurizing cylinder 7 through an air pipe 74. A solenoid valve 741 is also arranged at the bottom of the pressurizing cylinder 7. By controlling the switching state of the solenoid valve 741, the air pipe 74 can be opened and closed. A one-way valve 753 is arranged at the top opening of the air storage cylinder 75. The one-way valve 753 ensures that the gas can only flow into the air storage cylinder 75 in one direction to prevent gas backflow. When the crankshaft 3 continues to rotate, the crown gear 32 arranged at one end thereof drives the gear 5 8 meshing with it. As the gear 5 8 rotates, the reciprocating screw 81 arranged below also rotates. When the reciprocating screw 81 rotates, it causes the piston plate 71 to continuously move back and forth inside the pressurizing cylinder 7. As the piston plate 71 continuously rises and falls inside the pressurizing cylinder 7, the gas inside the pressurizing cylinder 7 is continuously compressed through the air pipe 1 74 and transported to the gas storage cylinder 75 for storage. This realizes the continuous compression and storage process of the gas.

[0059] A telescopic cylinder 76 is also provided on one side of the gas storage cylinder 75. One end of the telescopic cylinder 76 is connected to the bottom of the gas storage cylinder 75 through the air pipe 2 752. A solenoid valve 2 751 is provided at the bottom of the gas storage cylinder 75, and the opening and closing of the air pipe 2 752 is realized by controlling the state of the solenoid valve 2 751. A piston rod 764 capable of telescopic displacement is provided inside the telescopic cylinder 76. A spring 763 capable of rebounding is sleeved on one side of the outer surface of the piston rod 764. In addition, a solenoid valve 3 761 is provided on one side above the outer surface of the telescopic cylinder 76, and by controlling the state of the solenoid valve 3 761, the gas inside the telescopic cylinder 76 can be discharged when the piston rod 764 rebounds. When the piston rod 764 is displaced inside the telescopic cylinder 76, the spring 763 will help the piston rod 764 rebound. During the rebound process of the piston rod 764, the solenoid valve 3 761 can be opened to discharge the gas inside the telescopic cylinder 76.

[0060] A rack 762 is provided at the bottom of the piston rod 764, and the rack 762 is meshed and connected with the gear 4 62 below. At the same time, a flap groove 121 is opened downward on one side of the bottom surface of the feed port 12, and a flip plate 6 capable of flipping and throwing materials is provided inside the flap groove 121. A gear 3 61 is provided on one side of the hinged end of the flip plate 6, and the upper part of the gear 3 61 is meshed with the gear 4 62. When the gear 4 62 rotates, it drives the gear 3 61 to rotate, thereby driving the flip plate 6 to flip. After the raw material enters the inside of the impact box 11 through the feed port 12, the raw material is first impacted and crushed by the plate hammer 1 21. At the same time, under the rotation of the crankshaft 3, the crown gear 1 32 provided at one end of the crankshaft 3 drives the piston plate 71 to telescopically displace inside the pressurizing cylinder 7. With the reciprocating motion of the piston plate 71, the gas inside the pressurizing cylinder 7 is compressed and sent to the gas storage cylinder 75 through the air pipe 1 74 for storage. When the pressure inside the gas cylinder 75 reaches a predetermined value, the electromagnetic valve 2 751 provided at the bottom of the gas cylinder 75 opens, allowing the high-pressure gas inside the gas cylinder 75 to quickly enter the telescopic cylinder 76. After the high-pressure gas enters the telescopic cylinder 76, it pushes the piston rod 764 to move outward. The rack 762 at the bottom of the piston rod 764 moves accordingly, thereby driving the gear 4 62 to rotate. The rotation of the gear 4 62 will further drive the gear 3 61 meshing therewith, causing the gear 3 61 to rotate. As the gear 3 61 rotates, the flip plate 6 connected thereto quickly flips upward, throwing the raw materials above the flip plate 6 to the first impact plate 13, which helps to increase the crushing effect of the raw materials and improve the crushing efficiency. When the flip plate 6 completes the throwing action of the raw materials, the electromagnetic valve 3 761 provided above the telescopic cylinder 76 opens, allowing the gas in the telescopic cylinder 76 to be discharged. At this time, the piston rod 764 retracts under the action of the outer spring 763, causing the flip plate 6 in the flipped state to fall back downward. This intermittent unloading mechanism can not only avoid overloading of the crusher.

[0061] like Figure 7-10It is shown that when the water flow inside the butt joint 451 flows, the water flow velocity at this time flows by its own pressure, and the airflow discharged by the solenoid valve three 761 at this time cannot accelerate the flow of the water flow inside the butt joint 451. In order to solve the above problem, one end of the butt joint 451 is designed as an open structure, and the other end is equipped with a rotatable rotating shaft four 5. The blades 51 and the impeller 52 are respectively installed at both ends of the rotating shaft four 5, and the actual sizes of the blades 51 and the impeller 52 here are set to meet the use requirements. The blades 51 are located inside the butt joint 451, and the impeller 52 is wrapped by a volute 53. In addition, a connecting pipe 54 is connected between the inlet end of the volute 53 and the exhaust end of the solenoid valve three 761. When it is necessary to discharge gas from the inside of the telescopic cylinder 76, the solenoid valve three 761 will open, so that the gas can flow into the volute 53 through the connecting pipe 54. As the gas flows in, it will form a high-pressure airflow in the volute 53, which is sufficient to drive the impeller 52 to rotate. Since the impeller 52 and the paddle 51 are both mounted on the same rotating shaft 29 5, the rotation of the impeller 52 directly drives the paddle 51 to rotate together. The rotation of the paddle 51 produces a stirring effect, thereby helping to increase the flow rate of the solution inside the rotating shaft 2 4. In this way, not only is the effective discharge of gas achieved, but the circulation rate of the solution is also increased by utilizing the energy of the discharged gas.

[0062] The method for producing cement based on the slow setting of high-sulfur fly ash is carried out by using a cement raw material crushing device, wherein the raw materials are put into the cement raw material crushing device, wherein the raw materials include the following weight components as follows: Example

[0063] Clinker: 77.22 tons, slag powder: 5.94 tons, slag: 4.91 tons, high-sulfur fly ash 9.15 tons, desulfurization gypsum: 2.78 tons. Example

[0064] A high-sulfur fly ash is used as a retarding component, clinker: 76.3 tons, slag powder: 6.64 tons, slag: 5.12 tons, high-sulfur fly ash: 8.24 tons, desulfurized gypsum: 3.69 tons.

[0065] Among them, the above existing clinkers are all general-purpose Portland cement clinkers, and the chemical composition analysis of the above high-sulfur fly ash is shown in Table 1; the above cement was subjected to physical inspection and chemical analysis, and the results are shown in Table 2.

[0066] Table 1 Chemical composition analysis of high sulfur fly ash:

[0067] Table 2 is a comparative statistical analysis of the physical inspection and chemical analysis results of the large-mill test of producing slow-setting P.O42.5 cement using high-sulfur fly ash instead of ordinary fly ash and retarder:

[0068] Slow-setting 42.5 cement standards: flexural strength: initial setting time>240min, final setting time≥300min, 3d≥4.0MPa, 28d≥6.5MPa; compressive strength: 3d≥17MPa, 28d≥42.5MPa; MgO≤5.0%; CI-≤0.06%; SO3≤3.5%.

[0069] It can be seen from Table 2 that the initial setting time, final setting time, compressive strength, flexural strength, MgO, Cl-, and SO3 of No. 1 cement and No. 2 cement all meet the standards of slow-setting 42.5 cement, and their 3-day compressive strength and 28-day compressive strength are improved.

[0070] The working principle of the cement raw material crushing device is as follows: when crushing is required, the motor 16 is started, the motor 16 drives the gear 1 161 to rotate, and then drives the crown gear 2 33 meshing with it to rotate. As the crown gear 2 33 rotates, the crankshaft 3 connected to it also rotates. The rotation of the crankshaft 3 drives the first impact plate 13 to swing continuously through the connecting rod 132;

[0071] The crown gear 1 32 connected to one end of the crankshaft 3 will cause the piston plate 71 to perform telescopic movement in the pressurizing cylinder 7, thereby compressing the air in the pressurizing cylinder 7 and sending the compressed air into the air storage cylinder 75. When the air pressure in the air storage cylinder 75 reaches the set value, the solenoid valve 2 751 opens, and the high-pressure gas in the air storage cylinder 75 quickly enters the telescopic cylinder 76, pushing the piston rod 764 to move. The movement of the piston rod 764 drives the gear 4 62 through the rack 762 below, and the gear 4 62 drives the gear 3 61, and finally the flip plate 6 connected to the gear 3 61 flips upward. The flipping action of the flip plate 6 throws the raw material to the first impact plate 13, further improving the crushing efficiency and frequency. Afterwards, when the solenoid valve 3 761 on the telescopic cylinder 76 is opened, the piston rod 764 retracts under the action of the spring 763, so that the flip plate 6 returns to its initial position. This process realizes intermittent material discharge, helps to prevent equipment overload, and ensures that the raw material can enter the crushing area evenly, further optimizing the crushing effect;

[0072] Finally, when the gas inside the telescopic cylinder 76 needs to be discharged, the electromagnetic valve 3 761 is opened, and the discharged gas enters the volute 53 through the connecting pipe 54. These high-pressure gases drive the impeller 52 to rotate, and then drive the blade 51 at one end of the rotating shaft 4 5 to rotate. The rotation of the blade 51 increases the flow rate of the solution inside the rotating shaft 2 4, playing a role of auxiliary acceleration.

[0073] It should be noted that the specific models and specifications of the motor 16, solenoid valve 1 741, solenoid valve 2 751 and solenoid valve 3 761 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be repeated in detail.
