Description

Technical Field

[0001] The invention relates to the technical field of lightweight building material manufacturing, in particular to a lightweight brick raw material mixing and stirring device and process. Background Art

[0002] Lightweight bricks, as a building material, can reduce the weight of the floor. Lightweight bricks are usually made by mixing multiple materials, forming them under high pressure, and firing them at high temperature. The mixing steps of lightweight brick raw materials include:

[0003] 1. Dry mixing stage: put the aggregate, binder and dry powder additive into the mixer and mix at low speed (20-30 rpm) to ensure initial uniform dispersion;

[0004] 2. Wet mixing stage: slowly add water or liquid binder and stir at medium speed (30-40 rpm) to form a uniform slurry;

[0005] 3. Adding foaming agent: Add foaming agent in batches at the end of wet mixing and continue stirring at low speed to avoid bubble bursting.

[0006] The existing mixing equipment still has the following problems:

[0007] 1. Insufficient mixing of raw materials can easily cause slurry agglomeration. During the dry mixing stage, existing equipment usually increases the dry mixing time to ensure sufficient mixing of the raw materials, but this will lead to reduced efficiency;

[0008] 2. Lightweight aggregates (such as floating beads and expanded perlite) have low density and are easy to float. Aggregates and binders are easily separated, resulting in large density differences between the upper and lower layers of the slurry. This causes uneven pore distribution inside the finished bricks, low local strength, or fluctuating thermal insulation performance. Existing equipment uses traditional agitators, which are difficult to mix evenly when mixing large quantities, making it difficult to ensure that the slurry does not separate.

[0009] 3. The existing mixer blades are made of too hard material (such as metal blades), and lightweight aggregates (such as hollow balls and ceramsite) are easily squeezed and crushed during mixing, and the pore structure is destroyed;

[0010] 4. The foaming agent (such as rosin soap) needs to be in full contact with the slurry to form uniform micropores, but the traditional stirring device lacks equipment to ensure full contact and mixing of the foaming agent and the slurry;

[0011] 5. The slurry is easy to adhere to the inner wall of the mixing barrel during the mixing process, which can easily cause insufficient mixing. The existing device lacks equipment to separate the slurry from the mixing barrel.

[0012] Therefore, the present invention provides a lightweight brick raw material mixing and stirring device and process. Summary of the Invention

[0044] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0045] Example 1:

[0046] like Figures 1-9 As shown, the present invention provides a lightweight brick raw material mixing and stirring equipment, including: a frame 1, a mixing barrel 2 and a stirrer 3 are installed on the frame 1, a feeding mechanism 4 is provided on the mixing barrel 2, the feeding mechanism 4 includes a feeding box 41 fixedly installed on the top of the mixing barrel 2, the stirrer 3 includes a main shaft 31 rotatably installed in the mixing barrel 2 and a driving motor 32 installed on the frame 1 for driving the main shaft 31 to rotate, a plurality of groups of staggered stirring rollers 33 are provided on the main shaft 31, and stirring blades 34 are provided at both ends of the stirring rollers 33, an infusion machine 5 and a foaming machine 6 are installed on the frame 1, a transmission pipe 1 21 and a transmission pipe 2 42 are respectively installed on the mixing barrel 2 and the feeding box 41, the infusion machine 5 is connected to the transmission pipe 1 21, a transmission head 1 7 connected to the transmission pipe 1 21 is installed on the inner wall of the mixing barrel 2, the foaming machine 6 is connected to the transmission pipe 2 42, and a transmission head 2 8 connected to the transmission pipe 2 42 is installed on the inner wall of the mixing barrel 2.

[0047] like Figure 1 、 Figure 4-Figure 6As shown, when the present mixing equipment is used, aggregates, binders, dry powder additives, etc. are fed into the mixing barrel 2 through the feeding box 41 in the feeding mechanism 4, and the driving motor 32 is started to drive the main shaft 31 to rotate, thereby driving the stirring roller 33 on the main shaft 31 to rotate, and the mixed raw materials are mixed by the stirring roller 33 and the stirring blades 34 at both ends of the stirring roller 33; after mixing and stirring for a certain period of time, the infusion machine 5 is started to feed water or liquid binder into the bottom of the mixing barrel 2 through the transmission tube 1 21 and the transmission head 1 7, so that the water or liquid binder is mixed with the mixed raw materials, and a slurry is formed under the stirring of the stirring roller 33 and the stirring blades 34 at both ends of the stirring roller 33; after mixing and stirring for a certain period of time, the foaming machine 6 is started to foam the foaming agent and feed it into the mixing barrel 2 through the transmission tube 2 42 and the transmission head 2 8 to be mixed with the slurry.

[0048] The stirring blades 34 are used to turn the raw materials to increase the mixing uniformity; the stirring blades 34 are used to drive the slurry to rotate in the stirring barrel 2 to increase the mixing uniformity of the slurry, so that raw materials with different densities are mixed more evenly; the stirring blades 34 are used to stir the foaming agent entering the stirring barrel 2, thereby increasing the uniformity of the mixing of the foaming agent and the slurry.

[0049] like Figure 4-Figure 6 As shown, a plurality of feeding cavities 43 are provided in the feeding box 41, and an auger 44 is rotatably connected in the feeding cavity 43. The plurality of augers 44 are connected by a synchronous belt 45. A motor 46 for driving the synchronous belt 45 to rotate is installed on the feeding box 41. The feeding box 41 is provided with a feeding port 47 at the top of the feeding cavity 43, and the feeding box 41 is provided with a discharge port 48 at the bottom of the plurality of feeding cavities 43. The discharge port 48 is communicated with the mixing barrel 2.

[0050] like Figure 2-Figure 3 、 Figure 6 As shown, multiple discharge ports 48 are rotatably connected to baffles 49, and the feeding mechanism 4 also includes multiple gears 410, multiple racks 412 and multiple synchronous wheels 411. Multiple gears 410 are rotatably connected to the frame 1 and coaxially connected to the multiple baffles 49. Multiple racks 412 are slidably connected to the frame 1 and mesh with multiple gears 410. Multiple synchronous wheels 411 are equipped with synchronous belts 413. Motor 2 414 for driving the synchronous wheels 411 to rotate is installed on the frame 1. A limiting disk 415 is installed on one side of the synchronous wheel 411. A circular groove 416 is opened on one side of the limiting disk 415. A connecting rod 417 is fixedly connected to the rack 412. A limiting pin 418 is provided at one end of the connecting rod 417, and the limiting pin 418 is located in the circular groove 416.

[0051] When feeding, start the motor 1 46 to drive the synchronous belt 1 45 to rotate, thereby driving multiple screw dragons 44 to rotate synchronously, and feed a variety of raw materials into the feeding cavity 43 through multiple discharge ports 48, and the raw materials are evenly transported to the entire feeding cavity 43 through the screw dragon 44, and then start the motor 2 414 to drive the synchronous wheel 411 to rotate, and make multiple synchronous wheels 411 rotate synchronously through the synchronous belt 2 413. A limit plate 415 is installed on one side of the synchronous wheel 411, and the limit plate 415 is not coaxial with the synchronous wheel 411. When the synchronous wheel 411 rotates, it drives the limit plate 415 to rotate around the axis of the synchronous wheel 411, so The limit plate 415 rotates eccentrically, and because the limit pin 418 at one end of the connecting rod 417 is located in the circular groove 416 on the limit plate 415, and the connecting rod 417 and the rack 412 can only slide horizontally, when the limit plate 415 rotates, the circular groove 416 can drive the limit pin 418 to move back and forth, thereby driving the rack 412 to slide back and forth, and then driving the gear 1 410 meshing with the rack 412 to rotate back and forth, so that the baffle 49 coaxially connected to the gear 1 410 rotates back and forth, opening and closing the connecting space between the feeding chamber 43 and the mixing barrel 2, thereby intermittently feeding the raw materials into the mixing barrel 2.

[0052] The connecting passage between the feeding chamber 43 and the mixing barrel 2 is intermittently opened and closed by the reciprocating movement of the limit pin 418, so that the raw materials enter the mixing barrel 2 in stages and are stirred by the stirring roller 33 and the stirring blade 34, gradually increasing the amount of raw materials in the mixing barrel 2. The raw materials are stirred each time they are fed, so that the raw materials fed subsequently are mixed more evenly, thereby improving the mixing uniformity of multiple raw materials and improving the mixing efficiency.

[0053] It should be noted that, since aggregate accounts for a larger proportion of the raw materials, the feeding cavity 43 for inputting aggregate is larger.

[0054] One side of the synchronous wheel 411 is rotatably connected to a threaded rod 419 , and the limiting plate 415 is slidably connected to one side of the synchronous wheel 411 and is threadedly connected to the threaded rod 419 .

[0055] Because the limit plate 415 is slidably connected to one side of the synchronous wheel 411 and is threadedly connected to the threaded rod 419 on the synchronous wheel 411, the limit plate 415 can be driven to move by rotating the threaded rod 419, thereby changing the distance between the limit plate 415 and the axis of the synchronous wheel 411, that is, the eccentricity of the limit plate 415, thereby changing the moving distance of the connecting rod 417 and the rack 412, and then changing the rotation angle of the gear 410 and the baffle 49, and changing the amount of raw materials entering the mixing barrel 2; the amount of raw materials fed into the mixing barrel 2 by each feeding cavity 43 is adjusted by the threaded rod 419, thereby adjusting the ratio between different raw materials and improving the adaptability of the feeding mechanism 4.

[0056] like Figure 5-Figure 9As shown, a slot 36 is provided in the stirring roller 33, and the two ends of the stirring roller 33 are rotatably connected to a rotating shaft 37 at the slot 36. The stirring blade 34 is fixedly connected to the two ends of the rotating shaft 37 and is located on the outside of the stirring roller 33. The outside of the rotating shaft 37 is fixedly connected to a gear 2 38 in the stirring roller 33, and the two end faces of the stirring roller 33 are rotatably connected to a gear 3 39. A gear train 310 is installed between the gear 2 38 and the gear 3 39 in the slot 36, and a gear ring 311 is fixedly connected to the inside of the stirring barrel 2, and the gear ring 311 is meshed with the gear 3 39.

[0057] When the stirring roller 33 rotates, the gear three 39 at both ends of the stirring roller 33 engages with the ring gear 311 inside the stirring barrel 2, thereby rotating the gear three 39, so that the gear three 39 drives the gear two 38 to rotate through the gear system 310, and then drives the stirring blades 34 at both ends of the rotating shaft 37 to rotate, thereby increasing the uniformity of the slurry mixing.

[0058] The surfaces of the stirring roller 33 and the stirring blade 34 are covered with rubber to reduce the probability of the aggregate being squeezed and collided with the stirring roller 33 and the stirring blade 34 and damaged. A circular hole 35 is opened on the stirring blade 34, and the radius of the circular hole 35 is larger than the outer diameter of the aggregate. The circular hole 35 is used to evenly distribute the aggregate so that it is mixed more evenly with other raw materials.

[0059] It should be noted that the edge of the stirring blade 34 can fit with the stirring barrel 2, thereby separating the slurry adhering to the stirring barrel 2 from the stirring barrel 2 to avoid uneven stirring.

[0060] It should be noted that the length of the stirring blade 34 can be changed by changing the number of gears in the gear train 310 , thereby changing the stirring range of the stirring blade 34 .

[0061] like Figure 6 、 Figure 8 As shown, the mixing barrel 2 is provided with a sealing ring 312 on the outside of the gear ring 311, and sealing ring 1 313 is slidably connected on both sides of the sealing ring 312, and a sealing ring 2 314 is fixedly connected between the two sealing rings 1 313, and sealing sleeves 315 are provided on the outside of gear 3 39 at both ends of the mixing roller 33, and the sealing sleeve 315 is fixedly connected to the sealing ring 2 314.

[0062] When the stirring roller 33 rotates, the sealing sleeves 315 at both ends drive the sealing ring 2 314 and the sealing ring 1 313 to rotate in the sealing ring 312, thereby isolating the stirring roller 33 and the gear ring 311 to prevent the slurry from colliding with them, affecting the transmission and damaging the aggregate.

[0063] Example 2:

[0064] like Figure 5As shown, the transmission tube 21 is located at the outer bottom of the mixing barrel 2, and the transmission head 7 is fixedly installed at the inner bottom of the mixing barrel 2. There are multiple transmission heads 7, and the multiple transmission heads 7 are located between two adjacent mixing blades 34. The multiple transmission heads 7 are all fixedly connected to the transmission tube 21, and a one-way valve 71 is installed in the transmission head 7.

[0065] When water or liquid binder is added through the infusion machine 5, the water or liquid binder is dispersed into the mixing barrel 2 through the transmission head 7. During this period, the pressure of the water or liquid binder supplied by the infusion machine 5 opens the one-way valve 71, and at the same time, the one-way valve 71 prevents the slurry from entering the transmission head 7 and the transmission tube 21; when the gear 3 39 at one end of the stirring roller 33 rotates to the transmission head 7, the water and the mixed raw materials are mixed by the rotating stirring blade 34; the stirring blade 34 moves along with the stirring roller 33 and drives the mixed slurry to rotate along the mixing barrel 2, so that the mixed raw materials above enter the bottom of the mixing barrel 2 and are mixed with water or liquid binder through the stirring blade 34, so that part of the aggregate and other raw materials are fully mixed to form a slurry, thereby gradually mixing the mixed raw materials with water or liquid binder, avoiding the one-time addition of water or liquid binder that increases the difficulty of mixing and causes the aggregate and other raw materials to be stratified.

[0066] Example 3:

[0067] like Figure 5-Figure 6 As shown, the transmission tube 2 42 is located in the feeding box 41, and the transmission head 2 8 is fixedly installed on the top of the inner side of the mixing barrel 2, and multiple transmission heads 2 8 are provided. The multiple transmission heads 2 8 correspond to the multiple mixing blades 34, and the multiple transmission heads 2 8 are all fixedly connected to the transmission tube 2 42.

[0068] The foaming machine 6 inputs the foaming agent into the mixing barrel 2 through the transmission pipe 2 42 and the transmission head 2 8, and the transmission head 2 8 is set on the top of the mixing barrel 2, so that when the stirring blade 34 rotates at the top, the foaming agent entering the mixing barrel 2 can be attached to the stirring blade 34, and the rotating stirring blade 34 can mix the foaming agent with the slurry, so that the foaming agent and the slurry are fully mixed, thereby improving the mixing effect.

[0069] It should be noted that, by arranging the second transmission head 8 on the top of the mixing barrel 2 , the raw materials can be prevented from entering the second transmission head 8 and the second transmission tube 42 .

[0070] Example 4:

[0071] like Figures 1-9 As shown, a lightweight brick raw material mixing process includes the following steps:

[0072] S1. Start motor 1 46 and motor 2 414, driving the multiple augers 44 to rotate continuously and the multiple baffles 49 to rotate intermittently in sequence, feeding the raw materials in the feeding chamber 43 into the mixing barrel 2 for thorough mixing;

[0073] S2. Start the infusion machine 5 and feed water or liquid binder into the bottom of the mixing barrel 2 through the transmission tube 21 and the transmission head 7, so that the water or liquid binder is mixed with the mixed raw materials and a slurry is formed under the stirring of the stirring roller 33 and the stirring blades 34 at both ends of the stirring roller 33;

[0074] S3. After mixing and stirring for a certain period of time, the foaming machine 6 is started to foam the foaming agent and then sent into the mixing barrel 2 through the second transmission pipe 42 and the second transmission head 8 to mix with the slurry;

[0075] S4. Open the outlet at the bottom of the mixing barrel 2 to output the mixed raw materials.

[0076] The embodiments of the present invention are provided for the purpose of illustration and description.

Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
