Description
Technical Field
[0001] This invention relates to the field of thermal insulation mortar preparation technology, and in particular to a thermal insulation mortar and its production process. Background Technology
[0002] Mortar is a binding material used in bricklaying in construction. It is formed by mixing sand and cementing materials (cement, lime paste, clay, etc.) with water in a certain proportion. It is also called mortar. Due to the different construction areas and requirements, the raw materials and proportions required for mortar preparation are also different. Therefore, there are many types of mortar. Thermal insulation mortar is one of them. It is mainly used for thermal insulation of building exterior walls. It is usually made of various lightweight materials as aggregates, cement as binder, and some modified additives. It is a premixed dry powder mortar. In the preparation process of various thermal insulation mortars, uniformly mixing various raw materials is a very basic preparation step. However, in the current technology, when mixing solid raw materials and slurry raw materials, most of them are added to the slurry raw materials at the same time. This method requires a long mixing time, has low mixing efficiency, and because the addition position of solid raw materials is very fixed, it makes mixing difficult and makes it difficult to make the solid raw materials evenly distributed in the slurry raw materials.

[0034] S1. Put the inorganic cementitious material, fly ash and additives into a container connected to a stirring device;
[0035] S2. Add vitrified microspheres into the stirring device;

[0040] The specific steps in S4 are as follows:
[0041] S41: During the process of adding vitrified microspheres, multiple batches of vitrified microspheres are sprinkled out from different depths in the container by a stirring device;
[0042] S42: Periodically change the stirring depth of the stirring device, and continuously stir the material at that depth each time the vitrified microspheres are sprinkled out;

[0044] The additives in S1 consist of redispersible latex powder, wood fibers, cellulose ethers, and air-entraining agents.
[0045] The inorganic cementitious material in S1 is cement.
[0046] The container in S1 is a cylindrical container.
[0047] like Figure 4 , Figure 5 , Figure 6 and Figure 9 As shown:
[0048] The agitation device includes a vertical rod 101, a sliding seat 102 fixedly connected to the vertical rod 101, a rotating shaft 201 rotatably connected to the sliding seat 102, an agitator 202 connected to the rotating shaft 201, a stirring paddle detachably connected to the agitator 202 by bolts, a temporary storage section 301 rotatably connected to the sliding seat 102, multiple partitions 302 fixedly connected inside the temporary storage section 301, a side baffle 303 slidably connected to the temporary storage section 301, a fixing rod 103 fixedly connected to the sliding seat 102, an adding section 401 fixedly connected to the fixing rod 103, and a lower baffle 405 slidably connected to the adding section 401. The upper side of the adding part 401 has a longer opening, and the lower side of the adding part 401 has a shorter opening. The lower baffle 405 can block the shorter opening. A first motor that can drive the rotating shaft 201 to rotate is fixed on the sliding seat 102. A second motor that can drive the temporary storage part 301 to rotate is fixed on the sliding seat 102. A first electric push rod that can drive the sliding seat 102 to slide is fixed on the vertical rod 101. A second electric push rod that can push the lower baffle 405 to slide is fixed on the adding part 401. A through groove is opened on one side of the side baffle 303. The side baffle 303 can block the through groove.
[0049] Vitrified microspheres are added to the temporary storage section 301. The arrangement of multiple partitions 302 allows the vitrified microspheres to be divided into multiple portions, facilitating subsequent batch addition of vitrified microspheres. After the inorganic cementing material, fly ash, and additives are added to the container, the operable shaft 201 rotates on the sliding seat 102, causing the stirring paddle connected to the stirring section 202 to continuously stir the materials in the container, thereby mixing the materials in the container. At the same time, the operable sliding seat 102 rotates continuously on the vertical rod 101, thereby using the continuously rotating stirring section 202 to premix the materials, thereby achieving a mixing effect for the materials. During this process, the operable sliding seat 102 slides up and down on the vertical rod 101, thereby continuously changing the stirring height of the stirring section 202, so that the stirring paddle on the stirring section 202 can comprehensively stir the materials at different positions, thereby improving the stirring and mixing effect.
[0050] After the premixing operation is completed, the operable sliding seat 102 slides down the vertical rod 101 to a lower position. Then, the operating side baffle 303 slides to the left on the temporary storage section 301 until the first partition 302 is fully exposed. The operable temporary storage section 301 then rotates on the sliding seat 102 to an inclined position. At this time, the through groove is located on the lower side, allowing the vitrified microspheres separated by the first partition 302 to fall out of the through groove and into the addition section 401. In actual use, baffles should be provided on both the front and rear sides of the addition section 401. For ease of observation of other structures, the front baffle of the addition section 401 is not shown in the figure. The vitrified microspheres falling into the addition section 401 will automatically roll down along the addition section 401 to the lower side. Then, the lower baffle 405 can be slid to open the shorter opening on the lower side of the addition section 401. The vitrified microspheres leak out, allowing them to fall into the container at a suitable depth. As the stirring unit 202 continues to rotate, the vitrified microspheres quickly and evenly mix with the material at that depth. Then, the lower baffle 405 is reset and the sliding seat 102 slides upward, thereby changing the stirring depth of the stirring unit 202. At the same time, the adding unit 401 also slides upward with the sliding seat 102, thus changing the lowest point position of the adding unit 401. The above operation is then repeated, allowing the vitrified microspheres to be added to the material in batches from different depths. This allows the equipment to focus on stirring the material at that depth after each addition of vitrified microspheres, further improving the mixing effect between the vitrified microspheres and the original material, thereby increasing the mixing efficiency and improving the preparation efficiency of thermal insulation mortar.
[0051] like Figure 4 , Figure 6 , Figure 7 and Figure 9 As shown:
[0052] The device also includes a mating protrusion 403 fixedly connected to the adding part 401, an arc-shaped transmission part 402 fixedly connected to the adding part 401, a contact rod 203 fixedly connected to the stirring part 202, a striking ring 204 fixedly connected to the stirring part 202, the stirring part 202 being slidably connected to the rotating shaft 201, and a first compression spring fixedly connected between the stirring part 202 and the rotating shaft 201.
[0053] As the rotating shaft 201 rotates, it drives the stirring part 202 to rotate synchronously. During the process of mixing the vitrified microspheres with the original material, the contact rod 203 on the stirring part 202 can gradually contact the arc-shaped transmission part 402. As the rotating shaft 201 continues to rotate, the stirring part 202 will gradually slide upward on the rotating shaft 201. As a result, the stirring part 202 can reciprocate up and down at a high frequency while rotating, thereby providing a more comprehensive stirring effect for the material and improving the mixing efficiency.
[0054] Each time the stirring part 202 slides upward, it contacts the mating protrusion 403, causing the stirring part 202 to repeatedly strike the mating protrusion 403. This causes the adding part 401 to vibrate continuously. As the vitrified microspheres fall out of the adding part 401, the continuous vibration of the adding part 401 effectively prevents the vitrified microspheres from getting stuck together, thus ensuring that all the vitrified microspheres are discharged and avoiding material waste.
[0055] like Figure 7 As shown:
[0056] The device also includes a blower 404 that is detachably connected to the adding part 401 by bolts, with the air outlet of the blower 404 facing the lower side of the adding part 401.
[0057] The blower 404 is designed so that when adding vitrified microspheres and the lower baffle 405 needs to be slid open, the blower 404 can continuously supply downward airflow into the adding section 401. This allows the material around the adding section 401 in the container to be blown away, creating a certain amount of empty space around the adding section 401. This prevents material from flowing into the adding section 401 from below, thus ensuring the normal operation of subsequent additions of vitrified microspheres. At the same time, the downward airflow further facilitates the complete discharge of vitrified microspheres from the adding section 401, thereby further preventing material waste.
[0058] like Figure 6-8 As shown:
[0059] The device also includes a fixed base 501, a rotating push rod 502 rotatably connected to the fixed base 501, a cylindrical rod 304 fixedly connected to the side baffle 303, a second compression spring fixedly connected between the side baffle 303 and the adding part 401, and a third motor capable of driving the rotating push rod 502 to rotate fixedly connected to the fixed base 501.
[0060] When stirring the inorganic cementitious materials, fly ash and additives in the container, the rotating push rod 502 can be rotated to a vertical position to ensure that the cylindrical rod 304 will not come into contact with the rotating push rod 502 during the up and down sliding seat 102, thereby ensuring that the vitrified microspheres will not fall accidentally during the operation and ensuring that the stirring work is carried out stably.
[0061] When mixing vitrified microspheres with other materials, the rotary push rod 502 can be rotated to... Figure 9 As shown in the posture, during the subsequent gradual upward sliding of the sliding seat 102, the rotating push rod 502 will gradually push the side baffle 303 to slide on the temporary storage part 301 through the cylindrical rod 304, thereby gradually exposing the through groove. The further the sliding seat 102 is slid upward, the further the side baffle 303 will be pushed, and the more partitions 302 can be exposed, thereby achieving the effect of adding vitrified microspheres in batches and improving the subsequent mixing efficiency.
