Description

Technical Field

[0001] This invention relates to the field of thermal insulation mortar preparation technology, and more specifically to a thermal insulation mortar and its preparation process. Background Technology

[0002] Thermal insulation mortar is a premixed dry powder mortar made by mixing various lightweight materials as aggregates, cement as binder, and some modified additives. It is a building material used to construct the thermal insulation layer on building surfaces. Inorganic thermal insulation mortar, vitrified microsphere fireproof thermal insulation mortar, and composite silicate thermal insulation mortar are new types of thermal insulation and energy-saving mortar materials used for plastering the interior and exterior walls of buildings. Inorganic vitrified microspheres, or closed-cell expanded perlite, can be used as lightweight aggregates, and dry powder mortar composed of binders, crack-resistant additives, and other fillers is added. With its excellent properties such as energy saving and waste utilization, heat insulation, fire prevention and frost protection, and aging resistance, as well as its low price, thermal insulation mortar has a wide market demand. Thermal insulation mortar is usually made by mixing aggregates and cement with water. However, aggregates are usually in the form of blocks and powders. During transportation, powders are prone to clumping in humid environments. If the aggregate blocks are too large or the powders clump together, the quality of the mortar will be reduced. Therefore, the existing technology lacks a thermal insulation mortar preparation equipment and process that can screen aggregates. Summary of the Invention

[0026] The present invention will now be described in further detail with reference to the accompanying drawings.

[0027] The following is in conjunction with the appendix Figure 1 Detailed description: A thermal insulation mortar and its preparation process, the method comprising the following steps:

[0028] Step 1: Add aggregates and cement into the preparation device through the feeding port;

[0029] Step 2: Inject water into the preparation device through the inlet;

[0030] Step 3: The aggregate is sieved through a conical screen, and the mixing paddle I breaks up the clumps of powdery material;

[0031] Step 4: Stirring paddle II to mix the thermal insulation mortar, completing the preparation of the thermal insulation mortar.

[0032] The following is in conjunction with the appendix Figure 2-6 The preparation device includes a mixing tank 101, a conical screen 102, screen holes 103, slide rails I 104, sliders 105, baffle rings 106, a screening bucket 107, and a discharge bucket 108. The conical screen 102 is fixedly connected inside the mixing tank 101. The conical screen 102 is set as a cone with the top facing upward. Multiple screen holes 103 are evenly opened circumferentially on the conical screen 102. Multiple slide rails I 104 are fixedly connected to the mixing tank 101. A slider 105 is slidably connected to each slide rail I 104. The slide rails I 104 are used to make the slider 105 slide only along the axis of the slide rail I 104. Baffle rings 106 are fixedly connected to the multiple sliders 105. The screening bucket 107 is fixedly connected to the upper end of the multiple slide rails I 104. The discharge bucket 108 is fixedly connected to the mixing tank 101.

[0033] Furthermore, the mixing tank 101 serves as a mixing space, and the conical screen 102 acts as a screen, allowing aggregates of the appropriate particle size to pass through it. The conical screen 102 is designed in a conical shape, causing larger aggregates to slide down the conical surface to the periphery of the screen. The slider 105 allows the baffle ring 106 to slide up and down along the slide rail I 104. When the baffle ring 106 slides to the lower end of the slide rail I 104, the baffle ring 106 and the screen... The material bucket 107 and the conical screen 102 together form a screening bucket to complete the screening process. The baffle ring 106 blocks the aggregate to prevent it from sliding out of the conical screen 102. The aggregate passes through the conical screen 102 to complete the screening. When too many large aggregate particles accumulate on the conical screen 102, the baffle ring 106 slides to the upper end of the slide rail I 104. The unusable large aggregate particles slide from the gap between the conical screen 102 and the baffle ring 106 into the discharge bucket 108, completing the discharge of large aggregate particles.

[0034] The following is in conjunction with the appendix Figure 2-8 In detail, the preparation device further includes a gear box I 201, a slide rail II 202, a rack 203, a rotating shaft I 204, a gear 205, a handle 206, a connecting rod 207, and a spring 208. The gear box I 201 is fixedly connected to the discharge hopper 108. The slide rail II 202 is fixedly connected inside the gear box I 201. The rack 203 is slidably connected to the slide rail II 202. The rotating shaft I 204 is rotatably connected to the gear box I 201. I204 passes through gear box I201 and discharge bucket 108. Gear 205 is fixedly connected to shaft I204. Rack 203 meshes with gear 205. Handle 206 is fixedly connected to shaft I204. Connecting rod 207 is fixedly connected to rack 203. Connecting rod 207 is fixedly connected to retaining ring 106. Spring 208 is slidably connected to slide rail II202. Spring 208 is used to make rack 203 have a downward sliding tendency.

[0035] Furthermore, gear box I 201 provides support. Gear box I 201 has a shaft hole I, and rotating shaft I 204 is rotatably connected in the shaft hole I, allowing gear 205 to rotate within gear box I 201. Gear box I 201 has an opening I, through which connecting rod 207 passes. When handle 206 is pressed down, handle 206 drives gear 205 to rotate clockwise via rotating shaft I 204. Gear 205 drives rack 203 to slide upward, rack 203 compresses spring 208, causing spring 208 to contract. Rack 203 drives baffle ring 106 to slide upward via connecting rod 207, completing the discharge of large aggregate particles. When handle 206 is lifted, spring 208 extends, pushing rack 203 downward. Rack 203 drives 209 and gear 205 to rotate counterclockwise. Rack 203 drives baffle ring 106 to slide downward via connecting rod 207, completing the reset of the device.

[0036] The following is in conjunction with the appendix Figure 2-8 In detail, the preparation device also includes a barrel cover 301 and an opening 302.

A sliding ring 305 is fixedly connected to each of the two limiting rings 304. The sliding ring 305 is inclined with the left side higher than the right side.

[0039] Furthermore, the slide rail Ⅲ303 and the limiting ring 304 play a limiting role, so that the sliding ring 305 can only slide in the up and down direction. The sliding ring 305 is set in an inclined shape with the left side higher than the right side, so that the large aggregate particles falling on the sliding ring 305 can slide out of the opening 302 along the sliding ring 305.

[0043] Furthermore, the cam disk 309, rocker arm 310, and bracket II 311 form a cam rocker structure. Motor I 307 drives the cam disk 309 to rotate through the rotating shaft II 308. The cam disk 309 drives the bracket II 311 and the sliding ring 305 to move up and down reciprocally through the barrel cover 301, causing the sliding ring 305 to vibrate up and down, preventing large particles of aggregate on the sliding ring 305 from clogging and improving the smoothness of material discharge.

The lower end of gear box II 401 is provided with shaft hole III, and hollow tube 403 is rotatably connected in shaft hole III. Motor II 402 drives stirring shaft 404 to rotate. Stirring shaft 404 drives hollow tube 403 to rotate through bevel gear I 405, bevel gear II 406 and bevel gear III 408, causing hollow tube 403 to rotate. Stirring shaft 404 continues to rotate inside hollow tube 403. Stirring paddle I 409 can break up agglomerated powdery aggregate and push the aggregate to move on conical screen 102, improving the sieving efficiency of aggregate.
