Description

Technical Field

[0001] The present invention relates to the technical field of manufacturing light building materials, and particularly to a mixing and stirring device and process for raw materials of light bricks. Background Art

[0002] As a building material, light bricks can reduce the load on the floor. The production of light bricks usually involves mixing multiple materials and then forming them under high pressure and firing at high temperature. The stirring steps of the raw materials of light bricks include: 1. Dry mixing stage: Put the aggregate, binder, and dry powder additive into the mixer and mix at a low speed (20 - 30 rpm) to ensure preliminary uniform dispersion; 2. Wet mixing stage: Slowly add water or liquid binder and stir at a medium speed (30 - 40 rpm) to form a uniform slurry; 3. Addition of foaming agent: Add the foaming agent in portions in the later stage of wet mixing and continue to stir at a low speed to avoid bubble breakage.

[0003] The existing mixing and stirring equipment still has the following problems: 1. Inadequate mixing of raw materials is likely to cause the slurry to agglomerate. In the dry mixing stage, the existing equipment usually increases the dry mixing time to make the raw materials mix fully, but this will lead to a reduction in efficiency; 2. Lightweight aggregates (such as cenospheres, expanded perlite) have a low density and are easy to float, so it is easy for the aggregates and the binder to separate layers. The density difference between the upper and lower layers of the slurry is large, resulting in uneven distribution of pores inside the finished brick, low local strength or fluctuating heat insulation performance. The existing equipment uses traditional agitators and it is difficult to mix evenly during a large amount of mixing, and it is difficult to ensure that the slurry will not separate layers up and down; 3. The blades of the existing mixers are too hard (such as metal blades), and lightweight aggregates (such as hollow balls, ceramsite) are easily crushed by extrusion and collision during stirring, and the pore structure is damaged; 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 make the foaming agent and the slurry contact and mix fully; 5. The slurry is easily adhered to the inner wall of the stirring barrel during the mixing process, which is likely to cause insufficient mixing. The existing device lacks equipment to separate the slurry from the stirring barrel.

[0004] Therefore, the present invention provides a mixing and stirring device and process for raw materials of light bricks. Summary of the Invention

Detailed Embodiments

[0021] The following further describes in detail the embodiments of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0022] Embodiment 1: As Figures 1 - 9 shown, the present invention provides a lightweight brick raw material mixing and stirring device, including: a frame 1, a stirring barrel 2 and a stirrer 3 are installed on the frame 1, a feeding mechanism 4 is arranged on the stirring barrel 2, the feeding mechanism 4 includes a feeding box 41 fixedly installed on the top of the stirring barrel 2, the stirrer 3 includes a main shaft 31 rotatably installed in the stirring 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 arranged on the main shaft 31, stirring blades 34 are arranged at both ends of the stirring rollers 33, an infusion machine 5 and a foaming machine 6 are installed on the frame 1, a first transmission pipe 21 and a second transmission pipe 42 are respectively installed on the stirring barrel 2 and the feeding box 41, the infusion machine 5 is communicated with the first transmission pipe 21, a first transmission head 7 connected to the first transmission pipe 21 is installed on the inner wall of the stirring barrel 2, the foaming machine 6 is communicated with the second transmission pipe 42, and a second transmission head 8 connected to the second transmission pipe 42 is installed on the inner wall of the stirring barrel 2.

[0023] As Figure 1 、 Figures 4 - 6 shown, when this stirring device is in use, aggregates, binders, dry powder additives, etc. are fed into the stirring 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 rollers 33 on the main shaft 31 to rotate, and the mixed raw materials are mixed by the stirring rollers 33 and the stirring blades 34 at both ends of the stirring rollers 33; after mixing and stirring for a certain time, the infusion machine 5 is started, and water or liquid binder is fed into the bottom of the stirring barrel 2 through the first transmission pipe 21 and the first transmission head 7, so that the water or liquid binder is mixed with the mixed raw materials and forms a slurry under the agitation of the stirring rollers 33 and the stirring blades 34 at both ends of the stirring rollers 33; after mixing and stirring for a certain time, the foaming machine 6 is started, the foaming agent is foamed and fed into the stirring barrel 2 through the second transmission pipe 42 and the second transmission head 8 to be mixed with the slurry.

[0024] The raw materials are turned over by the stirring blades 34 to increase the mixing uniformity; the slurry is driven to rotate in the stirring barrel 2 by the stirring blades 34 to increase the mixing uniformity of the slurry, so that the raw materials with different densities are mixed more evenly; the foaming agent entering the stirring barrel 2 is stirred by the stirring blades 34, thereby increasing the mixing uniformity of the foaming agent and the slurry.

[0025] As Figures 4 - 6As shown in the figure, a plurality of feeding chambers 43 are provided in the feeding box 41. A screw 44 is rotatably connected in the feeding chamber 43. The plurality of screws 44 are connected by a first synchronous belt 45. A first motor 46 for driving the first 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 chamber 43, and the feeding box 41 is provided with a discharging port 48 at the bottom of each of the plurality of feeding chambers 43. The discharging port 48 communicates with the stirring barrel 2.

[0026] As Figures 2 - 3 , Figure 6 As shown in the figure, a baffle 49 is rotatably connected at each of the plurality of discharging ports 48. The feeding mechanism 4 further includes a plurality of first gears 410, a plurality of racks 412 and a plurality of synchronous wheels 411. The plurality of first gears 410 are rotatably connected to the frame 1 and are coaxially connected to the plurality of baffles 49. The plurality of racks 412 are slidably connected to the frame 1 and mesh with the plurality of first gears 410. A second synchronous belt 413 is installed on the plurality of synchronous wheels 411. A second motor 414 for driving the synchronous wheel 411 to rotate is installed on the frame 1. A limiting disc 415 is installed on one side of the synchronous wheel 411. A circular groove 416 is formed on one side of the limiting disc 415. A connecting rod 417 is fixedly connected to the rack 412. A limiting pin 418 is arranged at one end of the connecting rod 417. The limiting pin 418 is located in the circular groove 416.

[0027] During feeding, the first motor 46 is started to drive the first synchronous belt 45 to rotate, thereby driving the plurality of screws 44 to rotate synchronously, feeding a variety of raw materials into the feeding chamber 43 through the plurality of discharging ports 48, and uniformly conveying the raw materials to the entire feeding chamber 43 through the screws 44. Then the second motor 414 is started to drive the synchronous wheel 411 to rotate, and the plurality of synchronous wheels 411 are driven to rotate synchronously through the second synchronous belt 413. A limiting disc 415 is installed on one side of the synchronous wheel 411, and the limiting disc 415 is not coaxial with the synchronous wheel 411. When the synchronous wheel 411 rotates, it drives the limiting disc 415 to rotate around the axis of the synchronous wheel 411, so that the limiting disc 415 makes an eccentric rotation. Also, since the limiting pin 418 at one end of the connecting rod 417 is located in the circular groove 416 on the limiting disc 415, and the connecting rod 417 and the rack 412 can only slide horizontally, when the limiting disc 415 rotates, the circular groove 416 can drive the limiting pin 418 to make a reciprocating motion, thereby driving the rack 412 to slide reciprocally, and further driving the first gear 410 meshing with the rack 412 to rotate reciprocally, so that the baffle 49 coaxially connected to the first gear 410 rotates reciprocally, opening and closing the communication space between the feeding chamber 43 and the stirring barrel 2, thereby intermittently feeding the raw materials into the stirring barrel 2.

[0028] The communication channel between the feeding chamber 43 and the stirring barrel 2 is intermittently opened and closed by the reciprocating movement of the limit pin 418, so that the raw materials enter the stirring barrel 2 in stages, and are stirred by the stirring roller 33 and the stirring blades 34, gradually increasing the amount of raw materials in the stirring barrel 2. Each time the raw materials are fed, they are stirred, making the subsequent fed raw materials mix more evenly, thereby improving the mixing uniformity of various raw materials and the mixing efficiency.

[0029] It should be noted that since the proportion of aggregate in the raw materials is relatively large, the feeding chamber 43 for inputting aggregate is larger.

[0030] One side of the synchronous pulley 411 is rotatably connected with a threaded rod 419, and the limit disk 415 is slidably connected to one side of the synchronous pulley 411 and is threadedly connected with the threaded rod 419.

[0031] Since the limit disk 415 is slidably connected to one side of the synchronous pulley 411 and is threadedly connected with the threaded rod 419 on the synchronous pulley 411, by rotating the threaded rod 419, the limit disk 415 can be driven to move, thereby changing the distance between the limit disk 415 and the axis of the synchronous pulley 411, that is, the eccentricity of the limit disk 415, thereby changing the moving distances of the connecting rod 417 and the rack 412, and further changing the rotation angles of the first gear 410 and the baffle 49, and changing the amount of raw materials entering the stirring barrel 2; by adjusting the amount of raw materials fed into the stirring barrel 2 by each feeding chamber 43 through the threaded rod 419, the ratio between different raw materials can be adjusted, improving the adaptability of the feeding mechanism 4.

[0032] As Figures 5 - 9 As shown, an empty slot 36 is provided in the stirring roller 33. At both ends of the stirring roller 33, a rotating shaft 37 is rotatably connected at the empty slot 36. The stirring blades 34 are fixedly connected to both ends of the rotating shaft 37 and are located outside the stirring roller 33. A second gear 38 is fixedly connected to the outside of the rotating shaft 37 inside the stirring roller 33. At both end faces of the stirring roller 33, a third gear 39 is rotatably connected. A gear train 310 is installed between the second gear 38 and the third gear 39 in the empty slot 36. A gear ring 311 is fixedly connected to the inner side of the stirring barrel 2, and the gear ring 311 meshes with the third gear 39.

[0033] When the stirring roller 33 rotates, the third gears 39 at both ends of the stirring roller 33 mesh with the gear ring 311 on the inner side of the stirring barrel 2, so that the third gears 39 rotate, and the third gears 39 drive the second gear 38 to rotate through the gear train 310, and then drive the stirring blades 34 at both ends of the rotating shaft 37 to rotate, increasing the mixing uniformity of the slurry.

[0034] The surfaces of the stirring roller 33 and the stirring blades 34 are covered with rubber, which reduces the probability of the aggregate being damaged by extrusion and collision with the stirring roller 33 and the stirring blades 34. Moreover, round holes 35 are provided on the stirring blades 34, and the radius of the round holes 35 is greater than the outer diameter of the aggregate. The aggregate is evenly distributed through the round holes 35, making its mixing with other raw materials more uniform.

[0035] It should be noted that the edge of the stirring blade 34 can fit with the stirring barrel 2, so as to separate the slurry adhering to the stirring barrel 2 from the stirring barrel 2 and avoid uneven stirring.

[0036] It should be noted that by changing the number of gears in the gear train 310, the length of the stirring blade 34 can be changed, thereby changing the stirring range of the stirring blade 34.

[0037] As Figure 6 、 Figure 8 As shown in the figure, a sealing ring 312 is provided outside the gear ring 311 of the stirring barrel 2. Both sides of the sealing ring 312 are slidably connected with a first sealing ring 313. A second sealing ring 314 is fixedly connected between the two first sealing rings 313. Sealing sleeves 315 are provided outside the two ends of the stirring roller 33 and outside the third gear 39. The sealing sleeves 315 are fixedly connected with the second sealing ring 314.

[0038] When the stirring roller 33 rotates, the sealing sleeves 315 at both ends drive the second sealing ring 314 and the first sealing ring 313 to rotate within 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.

[0039] Embodiment 2: As Figure 5 As shown in the figure, the first transfer pipe 21 is located at the outer bottom of the stirring barrel 2. The first transfer heads 7 are fixedly installed at the inner bottom of the stirring barrel 2 and there are multiple of them. The multiple first transfer heads 7 are located between adjacent two stirring blades 34. The multiple first transfer heads 7 are all fixedly connected with the first transfer pipe 21. A one-way valve 71 is installed inside the first transfer head 7.

[0040] When adding water or liquid binder through the infusion machine 5, the water or liquid binder is dispersed into the mixing barrel 2 through the transfer head 1-7. During this process, 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 transfer head 1-7 and the transfer pipe 1-21. When the gear 39 at one end of the stirring roller 33 rotates to the position of the transfer head 1-7, the water and the mixed raw materials are mixed by the rotating stirring blades 34. While the stirring blades 34 follow the movement of the stirring roller 33, they drive the formed 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 the water or liquid binder through the stirring blades 34, enabling some of the aggregates to be fully mixed with other raw materials to form a slurry, thereby gradually mixing the mixed raw materials with the water or liquid binder, avoiding adding water or liquid binder at one time, increasing the mixing difficulty, and causing the aggregates and other raw materials to be stratified.

[0041] Embodiment Three: As Figures 5 - 6 shown, the transfer pipe 2-42 is located inside the feeding box 41, and the transfer head 2-8 is fixedly installed at the inner top of the mixing barrel 2 and is provided with a plurality of them. The plurality of transfer heads 2-8 correspond to the plurality of stirring blades 34, and the plurality of transfer heads 2-8 are all fixedly connected to the transfer pipe 2-42.

[0042] The foaming machine 6 inputs the foaming agent into the mixing barrel 2 through the transfer pipe 2-42 and the transfer head 2-8. The transfer head 2-8 is arranged at the top of the mixing barrel 2, so that when the stirring blades 34 rotate at the top, the foaming agent entering the mixing barrel 2 can be rolled onto the stirring blades 34, and the foaming agent and the slurry are mixed by the rotating stirring blades 34, so that the foaming agent and the slurry are fully mixed, improving the mixing effect.

[0043] It should be noted that arranging the transfer head 2-8 at the top of the mixing barrel 2 can also prevent raw materials from entering the transfer head 2-8 and the transfer pipe 2-42.

[0044] Embodiment Four: As Figures 1 - 9 shown, a lightweight brick raw material mixing and stirring process includes the following steps: S1. Start the motor 1-46 and the motor 2-414 to drive the plurality of augers 44 to rotate continuously and the plurality of baffles 49 to rotate intermittently in sequence, and feed the raw materials in the feeding chamber 43 into the mixing barrel 2 for full mixing; S2. Start the infusion machine 5, and feed water or liquid binder into the bottom of the mixing barrel 2 through the transfer pipe 1-21 and the transfer head 1-7, so that the water or liquid binder is mixed with the mixed raw materials and forms a slurry under the agitation of the stirring roller 33 and the stirring blades 34 at both ends of the stirring roller 33; S3. After mixing and stirring for a certain period of time, start the foaming machine 6 to foam the foaming agent and send it into the stirring barrel 2 through the second transfer pipe 42 and the second transfer head 8 to be mixed with the slurry; S4. Open the outlet at the bottom of the stirring barrel 2 to output the mixed raw materials.

[0045] The embodiments of the present invention are given for the purposes of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
