Description

Technical Field

[0001] The invention relates to the technical field of dry-mix mortar, and in particular to a method for preparing dry-mix mortar mixed with mineral powder. Background Art

[0002] Dry-mixed mortar (also called dry-powdered mortar in the early days) is usually called hydraulic cement mixed mortar. It refers to a granular or powdered material that is physically mixed in a certain proportion of dried and sieved aggregates (such as quartz sand), inorganic cementitious materials (such as cement) and additives (such as polymers). It is transported to the construction site in bagged or bulk form and can be used directly after adding water and mixing.

[0003] The role of mineral powder in dry-mixed mortar is mainly reflected in improving the workability, plasticity and water retention of mortar, and prolonging the setting time. If the mineral powder is not mixed evenly in the mortar, the performance of the mortar will be reduced, affecting the quality of the project. The degree of uniformity of the mixing of mineral powder in the mortar has a direct impact on its performance. In order to ensure the performance of the mortar and the quality of the project, it is necessary to ensure that the mineral powder is mixed evenly in the mortar.

[0004] In the process of mixing mineral powder and mortar, after adding the mineral powder, mixing is mainly achieved through stirring equipment, and there is no restriction on the adding method of the mineral powder. The mortar made in this way can easily cause uneven distribution of the mineral powder, affecting the quality of the mortar. Summary of the invention

[0005] The present invention discloses a method for preparing dry-mixed mortar doped with mineral powder, aiming to solve the technical problem that after adding the mineral powder, mixing is mainly achieved by a stirring device without restricting the adding method of the mineral powder, and the mortar prepared in this way is prone to uneven distribution of the mineral powder, thereby affecting the quality of the mortar.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A method for preparing dry-mixed mortar mixed with mineral powder comprises the following specific steps:

[0008] S1: crush the mortar raw materials, add the raw materials into the equipment according to the amount, and stir and mix them;

[0009] S2: Prepare mineral powder plasticizer;

[0010] S3: slowly add mineral powder plasticizer and continue stirring;

[0011] S4: Take out the dry mixed mortar for later use;

[0012] The mineral powder plasticizer comprises mineral powder, calcium formate, xanthan gum and seaweed powder, wherein the proportion of dry-mixed mortar aggregate, mineral powder, calcium formate, xanthan gum and seaweed powder is 1:0.6-0.7:0.05-0.15:0.02-0.03:0.05-0.06.

[0013] By adding calcium formate, xanthan gum and seaweed powder to the mineral powder plasticizer, the addition of mineral powder can improve the performance of dry-mixed mortar. However, due to the slower hydration rate of mineral powder than cement, under the same water-cement ratio, the mortar with mineral powder has more freezable water than the mortar without mineral powder, which reduces the frost resistance of the mortar. At the same time, the setting speed of the mortar will also be prolonged accordingly. The addition of calcium formate can help accelerate the setting speed. At the same time, the addition of xanthan gum and seaweed powder can optimize the viscosity of the mortar and increase the water consumption of the mortar. Therefore, the deficiency of mineral powder addition can be compensated in terms of accelerating the setting speed and increasing the amount of freezable water. Therefore, multi-directional optimization can be achieved to ensure the application range of the mortar.

[0014] A method for preparing dry-mixed mortar mixed with mineral powder, wherein the mixing equipment in S1 includes a mixing tank, a drying mechanism and a main feeding pipe connected to the top of the mixing tank at the same time, and a feeding mechanism arranged in the mixing tank; the feeding mechanism includes an annular bin movably connected to the mixing tank, a plurality of first leakage holes arranged at the bottom end of the annular bin, a plurality of second leakage holes arranged at chamfered positions in the annular bin, a plurality of support rods fixed at the chamfered positions in the annular bin, a plurality of cutting plates fixed to the outer periphery of the support rods, a gear ring fixed to the outer periphery of the annular bin, a gear meshed with one side of the gear ring, a second motor connected to the bottom end of the gear, and a connecting bin movably sleeved on one side of the annular bin.

[0015] A feeding mechanism is provided, which is used to add mineral powder during the mixing process of the dry-mixed mortar. During the process, the mineral powder is spread on the bottom of the annular bin. As the second motor drives the meshing gears and the gear ring to rotate rapidly, the mineral powder in the annular bin can leak out along the first leakage hole and enter the mixing tank to mix with the raw materials, thereby ensuring the uniform distribution of the mineral powder. At the same time, large pieces of mineral powder are thrown to the inner chamfer position under the action of the centrifugal force of the annular bin. After being pushed by the centrifugal force, they are placed in contact with multiple cutting plates, so that the powder can be broken up and discharged from the second leakage hole. Under this structure, the mineral powder can be broken up simultaneously while achieving uniform distribution, thereby ensuring the performance optimization effect of the mineral powder on the dry-mixed mortar.

[0016] In a preferred embodiment, a second support plate is fixedly connected to an outer wall of one side of the mixing tank, and the second motor is installed on the second support plate, a slide groove is provided on the inner wall of the mixing tank, and a gear ring is movably fitted on the inner wall of the slide groove, the top of the connecting bin is connected to the bottom end of the drying mechanism, and the drying mechanism includes a drying tank, a feeding port is fixedly connected to the inner wall of the top end of the drying tank, and a partition is fixedly connected to the inner wall of the bottom end of the drying tank, a notch is penetrated on the partition, and a funnel is fixedly connected to the inner wall of the bottom end of the drying tank, a second hygroscopic layer is fixedly connected to the top of the partition, and the first hygroscopic layer is fitted on the inner wall of the second hygroscopic layer, a second evaporation bin is provided in the middle of the first hygroscopic layer, and a plurality of first heating rods are provided in the second evaporation bin, A fourth hygroscopic layer is fixedly connected to the inner wall of the drying tank, and a third hygroscopic layer is laminated on the outer wall of the fourth hygroscopic layer, a first evaporation bin is provided on the third hygroscopic layer and the inner wall of the drying tank, and a second heating rod is provided on the first evaporation bin, the top outer walls of the first and second hygroscopic layers are fixedly connected to a cone support block, and a push plate is movably sleeved on the outside of the cone support block, a first motor is fixedly connected to the center position of the push plate, and the first motor is arranged in the cone support block, the bottom inner walls of the second evaporation bin and the first evaporation bin are simultaneously connected to a multi-way pipe, and one end of the multi-way pipe is connected to a dehumidifier, the dehumidifier is fixed to one side of the mixing tank through the first support plate, the second hygroscopic layer and the fourth hygroscopic layer are South Korean silk layers, and the first hygroscopic layer and the third hygroscopic layer are made of silicone gel.

[0017] By providing a drying mechanism, during the mixing process, the mineral powder enters the drying tank from the feeding port, and the mineral powder contacts the fourth hygroscopic layer and the second hygroscopic layer respectively. The high temperature environment causes the water in the mineral powder to be analyzed out and absorbed by the fourth hygroscopic layer and the second hygroscopic layer. Since the silicone gel material absorbs more water than South Korean silk, and South Korean silk has excellent moisture conduction effect, the moisture can be guided by the fourth hygroscopic layer and the second hygroscopic layer to be absorbed by the third hygroscopic layer and the first hygroscopic layer. The moisture in the third hygroscopic layer and the first hygroscopic layer is discharged to form water vapor, and is extracted by the dehumidifier along the multi-way pipe, thereby completing the drying of the mineral powder. Under this drying structure, the moisture of the mineral powder in the stacking process can be effectively guided, thereby avoiding loss during the drying process of the mineral powder.

[0018] As can be seen from the above, a method for preparing dry-mixed mortar mixed with mineral powder, the mixing equipment in S1 includes a mixing tank, a drying mechanism and a main feeding pipe connected to the top of the mixing tank at the same time, and a feeding mechanism arranged in the mixing tank; the feeding mechanism includes an annular bin movably connected to the mixing tank, a plurality of first leakage holes arranged at the bottom of the annular bin, a plurality of second leakage holes arranged at the chamfered position in the annular bin, a plurality of support rods fixed at the chamfered position in the annular bin, a plurality of cutting plates fixed to the outer periphery of the support rods, a gear ring fixed to the outer periphery of the annular bin, a gear meshed with one side of the gear ring, a second motor connected to the bottom of the gear, and a connecting bin movably sleeved on one side of the annular bin. The method for preparing dry-mixed mortar mixed with mineral powder provided by the present invention has the technical effect of achieving uniform distribution of mineral powder while also being able to simultaneously crush the mineral powder, thereby ensuring the performance optimization effect of mineral powder on dry-mixed mortar.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] The invention discloses a method for preparing a dry-mixed mortar mixed with mineral powder, which is mainly used in the mixing scene of dry-mixed mortar.

[0028] Reference Figure 6 A method for preparing dry-mixed mortar containing mineral powder comprises the following specific steps:

[0029] S1: crush the mortar raw materials, add the raw materials into the equipment according to the amount, and stir and mix them;

[0030] S2: Prepare mineral powder plasticizer;

[0031] S3: slowly add mineral powder plasticizer and continue stirring;

[0032] S4: Take out the dry mixed mortar for later use;

[0033] The mineral powder plasticizer includes mineral powder, calcium formate, xanthan gum and seaweed powder, wherein the ratio of dry-mixed mortar aggregate, mineral powder, calcium formate, xanthan gum and seaweed powder is 1:0.6-0.7:0.05-0.15:0.02-0.03:0.05-0.06;

[0034] By adding calcium formate, xanthan gum and seaweed powder to the mineral powder plasticizer, the addition of mineral powder can improve the performance of dry-mixed mortar. However, due to the slower hydration rate of mineral powder than cement, under the same water-cement ratio, the mortar with mineral powder has more freezable water than the mortar without mineral powder, which reduces the frost resistance of the mortar. At the same time, the setting speed of the mortar will also be prolonged accordingly. The addition of calcium formate can help accelerate the setting speed. At the same time, the addition of xanthan gum and seaweed powder can optimize the viscosity of the mortar and increase the water consumption of the mortar. Therefore, the deficiency of mineral powder addition can be compensated in terms of accelerating the setting speed and increasing the amount of freezable water. Therefore, multi-directional optimization can be achieved to ensure the application range of the mortar.

[0035] Reference Figure 1-Figure 4 , a method for preparing dry-mixed mortar with mineral powder, the mixing equipment in S1 includes a mixing tank 2, a drying mechanism 1 and a main feeding pipe 4 connected to the top of the mixing tank 2, and a feeding mechanism 3 arranged in the mixing tank 2; the feeding mechanism 3 includes an annular bin 307 movably connected to the mixing tank 2, a plurality of first leakage holes 308 arranged at the bottom of the annular bin 307, a plurality of second leakage holes 309 arranged at the chamfered position in the annular bin 307, a plurality of support rods 310 fixed at the chamfered position in the annular bin 307, and a plurality of support rods 311 fixed to the support rods 312. A plurality of cutting plates 311 on the periphery of the rod 310, a toothed ring 306 fixed to the periphery of the annular bin 307, a gear 301 meshed with one side of the toothed ring 306, a second motor 303 connected to the bottom end of the gear 301, and a connecting bin 305 movably sleeved on one side of the annular bin 307, the feeding mechanism 3 is used to add mineral powder during the mixing process of the dry-mixed mortar. After the mineral powder is dried by the drying mechanism 1, when it passes through the connecting bin 305 and enters the annular bin 307, the mineral powder can be spread flat through the guidance and restriction of the connecting bin 305 on the mineral powder. At the bottom of the annular bin 207, as the second motor 303 drives the meshing gear 301 and the gear ring 306 to rotate rapidly, the mineral powder in the annular bin 207 can leak out along the first leakage hole 208 and enter the mixing tank 2 to mix with the raw material. Due to the light weight of the mineral powder, when entering the mixing tank 2, it is further dispersed during the floating process, so that it can be evenly spread on the surface of the raw material. In the process of continuous mixing and continuous feeding of the mineral powder, the uniform distribution of the mineral powder can be guaranteed. At the same time, the mineral powder dried by the drying mechanism 1 As some powder clumps have not been broken up, they cannot be dispersed. The powdered mineral powder will fall down through the first leakage hole 308 and the second leakage hole 309. Large pieces of mineral powder clumps are thrown to the inner chamfer position under the centrifugal force of the annular bin 307. Pushed by the centrifugal force, they are placed in contact with multiple cutting plates 311, so that the powder clumps can be broken up and discharged from the second leakage hole 309. Under this structure, the mineral powder can be evenly distributed and broken up at the same time, thereby ensuring the performance optimization effect of the mineral powder on the dry-mixed mortar.

[0039] Reference Figure 5 In a preferred embodiment, a fourth hygroscopic layer 114 is fixedly connected to the inner wall of the drying tank 102, and a third hygroscopic layer 113 is laminated on the outer wall of the fourth hygroscopic layer 114, a first evaporation bin 112 is disposed between the third hygroscopic layer 113 and the inner wall of the drying tank 102, and a second heating rod 118 is disposed in the first evaporation bin 112.

[0040] Reference Figure 5 In a preferred embodiment, the top outer walls of the first hygroscopic layer 110 and the second hygroscopic layer 111 are fixedly connected with a cone support block 117, and a push plate 107 is movably sleeved outside the cone support block 117, and a first motor 115 is fixedly connected with the center position of the push plate 107, and the first motor 115 is arranged inside the cone support block 117.

[0042] Reference Figure 5In a preferred embodiment, the second hygroscopic layer 111 and the fourth hygroscopic layer 114 are South Korean silk layers, and the first hygroscopic layer 110 and the third hygroscopic layer 113 are made of silicone gel. During the mixing process, the mineral powder enters the drying tank 102 from the feeding port 101, and gradually reduces the thickness of the mineral powder through the transition of the cone support block 117. The push plate 107 is driven by the first motor 115 to rotate to push the mineral powder from the slot 106 to the funnel 105 for temporary storage, and then to the communication warehouse 305. When in the drying tank 102, the mineral powder contacts the fourth hygroscopic layer 114 and the second hygroscopic layer 111 respectively, and the high temperature environment causes the water in the mineral powder to be analyzed out. The moisture is absorbed by the fourth hygroscopic layer 114 and the second hygroscopic layer 111. Since silicone gel material absorbs more water than South Korean silk and South Korean silk has excellent moisture conduction effect, the moisture can be guided by the fourth hygroscopic layer 114 and the second hygroscopic layer 111 to be absorbed by the third hygroscopic layer 113 and the first hygroscopic layer 110. After being heated by the heating rod, the moisture in the third hygroscopic layer 113 and the first hygroscopic layer 110 is discharged to form water vapor, and is extracted by the dehumidifier 103 along the multi-way pipe 119, thereby completing the drying of the mineral powder. Under this drying structure, the moisture of the mineral powder in the stacking process can be effectively guided, thereby avoiding loss during the drying process of the mineral powder.

[0043] Working principle: During the mixing process, the mineral powder enters the drying tank 102 from the feeding port 101, and gradually reduces the thickness of the mineral powder through the transition of the cone support block 117. The first motor 115 drives the push plate 107 to rotate to push the mineral powder from the slot 106 to the funnel 105 for temporary storage, and then leads to the connecting warehouse 305. When in the drying tank 102, the mineral powder contacts the fourth hygroscopic layer 114 and the second hygroscopic layer 111 respectively. The high temperature environment causes the water in the mineral powder to be analyzed and absorbed by the fourth hygroscopic layer 114 and the second hygroscopic layer 111. Because the silicone gel material is more absorbent than the South Korean silk, and the South Korean The silk has an excellent moisture conduction effect, so the fourth moisture absorption layer 114 and the second moisture absorption layer 111 can guide the moisture to the third moisture absorption layer 113 and the first moisture absorption layer 110 for absorption. After being heated by the heating rod, the moisture in the third moisture absorption layer 113 and the first moisture absorption layer 110 is discharged to form water vapor, and is extracted by the dehumidifier 103 along the multi-way pipe 119, thereby completing the drying of the mineral powder. Under this drying structure, the moisture of the mineral powder in the stacking process can be effectively guided, thereby avoiding the loss of the mineral powder during the drying process. At the same time, the feeding mechanism 3 is used to add mineral powder in the mixing process of the dry mixed mortar. The mineral powder is dried After the mechanism 1 is dried, when it passes through the interconnecting bin 305 and enters the annular bin 307, the interconnecting bin 305 guides and restricts the mineral powder, so that the mineral powder can be spread on the bottom of the annular bin 207. As the second motor 303 drives the meshing gear 301 and the gear ring 306 to rotate rapidly, the mineral powder in the annular bin 207 can leak out through the first leakage hole 208 and enter the mixing tank 2 to mix with the raw material. Since the mineral powder is light in weight, it is further dispersed during the floating process when entering the mixing tank 2, so that it can be evenly spread on the surface of the raw material. During the continuous mixing and continuous feeding of the mineral powder, , which can ensure the uniform distribution of the mineral powder. At the same time, the mineral powder after drying by the drying mechanism 1 is not broken, resulting in some powder clumps not being dispersed. The powdered mineral powder will fall along the first leakage hole 308 and the second leakage hole 309, and the large pieces of mineral powder clumps are thrown to the inner chamfer position under the action of the centrifugal force of the annular bin 307. After being pushed by the centrifugal force, they are placed in contact with multiple cutting plates 311, so that the powder clumps can be broken and discharged from the second leakage hole 309. Under this structure, the mineral powder can be broken simultaneously while achieving uniform distribution of the mineral powder, thereby ensuring the performance optimization effect of the mineral powder on the dry mixed mortar.
