[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0032] The following is combined with Figure 1 Detailed description, a method for preparing high-resistance and high-performance cement, the preparation method comprising the following steps:

[0036] Step 4: Stir the various materials in the processing barrel 101 to complete the preparation of high-resistance and high-performance cement.

[0037] The following is combined with Figure 1 Specifically speaking, the ratio of the water reducing agent to water in step three is 1:5.

[0038] Furthermore, a ratio of water reducer to water of 1:5 can bring out the maximum effect of the water reducer, allowing the high-resistance and high-performance cement to have better strength.

[0039] The following is combined with Figure 2-7 In detail, the preparation device includes a processing barrel 101, support legs 102, a mud discharge pipe 103, a top sealing plate 201, a feeding hole 202, four auxiliary material holes 203 and a drainage ring 206. The supporting legs 102 are fixedly connected to the processing barrel 101 by welding, the mud discharge pipe 103 is fixedly connected to the bottom of the processing barrel 101 by welding, the top sealing plate 201 is fixedly connected to the processing barrel 101 by multiple screws, a feeding hole 202 and four auxiliary material holes 203 are all arranged on the top sealing plate 201, and the drainage ring 206 is fixedly connected to the processing barrel 101 by welding.

[0040] Furthermore, the processing barrel 101 is provided with a stirring mechanism, which can add various materials and water into the processing barrel 101. The stirring mechanism on the processing barrel 101 can be used to stir various materials in the processing barrel 101. The bottom surface of the processing barrel 101 is designed with a conical structure, which is convenient for discharging the high-resistance and high-performance cement processed in the processing barrel 101. The processing barrel 101 is provided with a protruding ring, and the support leg 102 is fixedly connected to the processing barrel 101 and contacts with the protruding ring. The support leg 102 is fixed by the protruding ring, which can make the support leg 102 more secure and prevent the support leg 102 from detaching from the processing barrel 101. The high-resistance and high-performance cement processed in the processing barrel 101 can be discharged from the mud discharge pipe 103. The mud discharge pipe 103 is provided with a valve, and the valve can be used to change whether there is processed high-resistance in the mud discharge pipe 103. High-performance cement can be discharged, and the top sealing plate 201 can seal the opening above the processing barrel 101 to prevent debris from entering the processing barrel 101, and the feeding hole 202 can provide space for adding cement, sand and stone raw materials, and the four auxiliary material holes 203 can provide space for adding four auxiliary materials: fly ash, mineral powder, slag and silica powder, so that cement, sand, stone raw materials, fly ash, mineral powder, slag and silica powder can be added to the processing barrel 101, and a plurality of drainage holes are arranged under the drainage ring 206, and a mixture of water reducer and water can be added to the drainage ring 206, and the mixture of water reducer and water is discharged through the plurality of drainage holes on the drainage ring 206 and enters the processing barrel 101, so that the mixture of water reducer and water is mixed with a variety of materials in proportion and stirred to complete the preparation of high-resistance and high-performance cement.

[0041] According to the instruction manual Figure 2-4 In detail, the preparation device further comprises a collecting chamber 204 and a spiral plate 205 . The collecting chamber 204 is fixedly connected to the drain ring 206 by welding, and the spiral plate 205 is fixedly connected below the collecting chamber 204 by welding.

[0042] Further, such as Figure 3 and 4 It can be seen that the collecting chamber 204 is designed as a conical surface, and a straight circular tube is arranged below it. The spiral plate 205 is fixedly connected in the straight circular tube. The collecting chamber 204 is located below a feeding hole 202 and four auxiliary material holes 203. When multiple materials fall from a feeding hole 202 and four auxiliary material holes 203, they can flow directly to the collecting chamber 204, and the mixture of water reducer and water discharged through the drainage ring 206 can also flow to the collecting chamber 204. Finally, the mixture of multiple materials, water reducer and water can flow down from the conical surface of the collecting chamber 204 and be discharged through the straight circular tube. Moreover, when the mixture of multiple materials, water reducer and water enters the straight circular tube on the collecting chamber 204, it will move downward along the spirality of the spiral plate 205, so that the mixture of multiple materials, water reducer and water can be mixed for the first time, which can speed up the mixing speed of the mixture of multiple materials, water reducer and water, and further improve the preparation speed of high-resistance and high-performance cement.

[0043] According to the instruction manual Figure 2-5 In detail, the preparation device also includes a connecting pipe 207, an enlarged cone mouth 208 and a supporting plate 209. The connecting pipe 207 is fixedly connected to the drainage ring 206 by welding, the enlarged cone mouth 208 is fixedly connected to the connecting pipe 207 by welding, the supporting plate 209 is fixedly connected to the processing barrel 101 by welding, and the connecting pipe 207 and the supporting plate 209 are fixedly connected by welding.

[0044] Furthermore, both left and right ends of the drain ring 206 are provided with liquid inlet ports, and both ends of the connecting pipe 207 are fixedly connected to the two liquid inlet ports on the drain ring 206, respectively, and the mixture of water reducer and water in the connecting pipe 207 will enter the drain ring 206. After the enlarged cone port 208 is provided, the enlarged cone port 208 is provided to facilitate the addition of the mixture of water reducer and water. The mixture of water reducer and water can be added to the enlarged cone port 208, and then enter the connecting pipe 207, and finally flow into the drain ring 206, and then be discharged through the multiple drainage holes on the drain ring 206. Only then can the mixing of various materials with the mixture of water reducer and water be achieved. The supporting plate 209 is provided to play a supporting role, which can achieve the fixing of the connecting pipe 207 to prevent the connecting pipe 207 from tilting when the mixture of water reducer and water enters the connecting pipe 207, thereby affecting the mixing of various materials with the mixture of water reducer and water.

[0045] According to the instruction manual Figure 6-8In detail, the preparation device also includes a material transfer chamber I301, a rotating plate 302, a transmission rod 303, four material transfer chambers II304 and four leakage plates 305. The material transfer chamber I301 is fixedly connected to the feeding hole 202 by welding, the transmission rod 303 is rotatably connected to the material transfer chamber I301 through a circular hole, the rotating plate 302 is slidably connected to the transmission rod 303 through a keyway, the rotating plate 302 is located in the material transfer chamber I301, the four material transfer chambers II304 are respectively fixedly connected to the four auxiliary material holes 203 by welding, the four leakage plates 305 are all slidably connected to the transmission rod 303 through keys, and the four leakage plates 305 are respectively rotatably connected to the four material transfer chambers II304.

[0046] Furthermore, the material transfer chamber I301 plays a role in transmission, and the transmission rod 303 can provide a space for the rotating plate 302 to rotate. When a variety of materials fall onto the rotating plate 302, the transmission rod 303 will be driven to rotate. When a variety of materials are placed in the material transfer chamber I301, the rotating plate 302 will be driven to rotate, and the rotating rotating plate 302 will drive the transmission rod 303 to rotate. The four material transfer chambers II304 are respectively connected to the storage barrels storing fly ash, mineral powder, slag and silicon powder. When the transmission rod 303 rotates, the four leakage plates 305 can be driven to rotate. Figure 8 As shown, four through holes are provided on the leak plate 305. When the four leak plates 305 rotate, the four through holes will be intermittently in a vertical state. When the four through holes are in the vertical state, fly ash, mineral powder, slag and silicon powder will slide out from the vertical through holes and finally be discharged from the four material transfer chambers II304. Finally, the fly ash, mineral powder, slag and silicon powder will enter the processing barrel 101, so that when the cement, sand and stone raw materials fall, there will be fly ash, mineral powder, slag and silicon powder falling, realizing the proportional mixing of multiple raw materials. No manual proportioning is required to achieve the mixing of multiple materials, thereby further improving the preparation efficiency of high-resistance and high-performance cement.

[0047] According to the instruction manual Figure 6-10 In detail, the preparation device also includes a crushing chamber 501, two supporting rings 502 and four material storage barrels 306. The crushing chamber 501 is fixedly connected to the material transfer chamber I301 by welding. The two supporting rings 502 are fixedly connected to the crushing chamber 501 by welding. The four material storage barrels 306 are respectively fixedly connected to the two supporting rings 502 by welding. The four material storage barrels 306 are respectively fixedly connected to the four material transfer chambers II304.

[0048] Furthermore, fly ash, mineral powder, slag and silicon powder can be placed in the crushing chamber 501. The bottom of the crushing chamber 501 is designed as a cone, and a plurality of leakage holes are arranged on the plane at the bottom. Raw materials that meet the standards will fall from the plurality of leakage holes and enter the transfer chamber I301. When the raw materials enter the transfer chamber I301, they will drive the transfer plate 302 to rotate to realize the falling processing of the raw materials. The two supporting rings 502 can provide a fixed space for the four storage barrels 306, and the fly ash, mineral powder, slag and silicon powder are stored in the four storage barrels 306 respectively. In this way, when the raw materials fall, the four transmission rods 303 can be driven to rotate, thereby driving the four transfer plates 305 to rotate, so that the fly ash, mineral powder, slag and silicon powder can be allowed to fall, so as to realize the proportional mixing of the raw materials with fly ash, mineral powder, slag and silicon powder, and further accelerate the preparation of high-resistance and high-performance cement.

[0049] According to the instruction manual Figure 6 and 7 In detail, the preparation device further includes two elastic telescopic rods 401 , and the two elastic telescopic rods 401 are fixedly connected to the top sealing plate 201 by welding, and the two elastic telescopic rods 401 are in contact with the transmission rod 303 .

[0050] Furthermore, the elastic telescopic rod 401 consists of a sliding cavity and a sliding rod, which is slidably connected in the sliding cavity. A spring is arranged in the sliding cavity, and the elastic force generated by the spring acts on the sliding rod, so that the sliding rod generates an upward moving force, thereby making the sliding rod contact with the transmission rod 303. At this time, the transmission rod 303 will be limited to prevent the transmission rod 303 from rotating when no raw materials fall into the transfer cavity I301. In this way, fly ash, mineral powder, slag and silicon powder will not enter the four transfer cavities II304, thereby further ensuring the proportional mixing of the raw materials with fly ash, mineral powder, slag and silicon powder. Only when the raw materials fall into the transfer cavity I301, the transfer plate 302 will drive the transmission rod 303 to rotate, thereby realizing the precise falling of fly ash, mineral powder, slag and silicon powder.

[0051] According to the instruction manual Figure 2 , 3 10 , the preparation device further comprises a crushing component, which is connected to the crushing chamber 501 .

[0052] Furthermore, the crushing components can be used to crush cement, sand and stone raw materials, further ensuring that the cement, sand and stone raw materials will be turned into powder. Only after the cement, sand and stone raw materials are turned into powder can they be discharged from the crushing chamber 501.

[0053] The crushing component includes a bearing seat 601, a crushing roller 602, a main rotating square shaft 603, a square cover plate 604 and a pushing plate 605. The bearing seat 601 is fixedly connected in the crushing chamber 501 by welding. The crushing roller 602 is rotatably connected to the bearing seat 601 through a circular hole. The crushing roller 602 is rotatably connected to the crushing chamber 501 through a stepped column. The crushing roller 602 is slidably connected to the main rotating square shaft 603 through a square slide groove. The main rotating square shaft 603 is rotatably connected to the bearing seat 601 through a circular shaft. The square cover plate 604 is fixedly connected to the crushing roller 602 by multiple screws. The square cover plate 604 is slidably connected to the main rotating square shaft 603 through a square opening. A plurality of pushing plates 605 are fixedly connected to the crushing roller 602 by welding. The plurality of pushing plates 605 are all slidably connected between the crushing chamber 501 and the crushing roller 602.

[0054] Furthermore, the bearing seat 601 can provide a rotation space for the crushing roller 602 and the main rotating square shaft 603, and the square cover plate 604 can limit the main rotating square shaft 603 to prevent the main rotating square shaft 603 from being separated from the crushing roller 602. A reduction motor is fixedly connected to the bearing seat 601, and the output shaft of the reduction motor is fixedly connected to the main rotating square shaft 603. A spring I is arranged between the crushing roller 602 and the main rotating square shaft 603, and the elastic force generated by the spring is applied to the crushing roller 602. A stepped column is fixedly connected to the center of the bottom of the crushing chamber 501, and the stepped column is rotatably connected to the crushing roller 602. When the crushing roller 602 is at the lowest point, it will contact the large cylinder of the stepped column, so that a certain gap will be left between the crushing roller 602 and the crushing chamber 501, so that the cement After the raw materials of cement, sand and stone are added into the crushing chamber 501, the reduction motor is started to drive the main rotating square shaft 603 to rotate, and the rotating main rotating square shaft 603 can drive the crushing roller 602 to rotate, and then the cement, sand and stone raw materials between the crushing chamber 501 and the crushing roller 602 can be crushed to ensure that the cement, sand and stone raw materials are in powder form. The raw materials crushed into powder will be discharged from the multiple leakage holes below the crushing chamber 501, and when the crushing roller 602 encounters relatively hard and large pieces of raw materials, the crushing roller 602 will move upward to protect itself without delaying its own rotation. After the relatively hard and large pieces of raw materials are crushed, the crushing roller 602 will return to the lowest point to achieve the crushing of the raw materials.
