DETAILED DESCRIPTION

[0029] refer to Figure 1 , 2 , 5 and 6, detailed description of the embodiment of processing water reducing agent:

[0030] A concrete water reducing agent processing device comprises a base frame 11 and two slideways 12 fixedly connected to the upper part of the base frame 11, wherein an arc frame 22 is slidably connected in each slideway 12, and the two arc frames 22 are fixedly connected to a processing barrel 21, and a temperature sensor 25 is provided on the processing barrel 21, and the reaction temperature of the material can be monitored by the temperature sensor 25. An inner ring 24 and an outer ring 28 are fixedly connected to the upper part of the processing barrel 21, and a revolving frame 31 is rotatably connected to the inner ring 24, a connecting pipe 32 is fixedly connected to the upper part of the revolving frame 31, and a plurality of stirring frames 33 are fixedly connected to the lower part of the revolving frame 31, the revolving frame 31 and the plurality of stirring frames 33 are hollow inside, and the revolving frame 31, the connecting pipe 32 and the plurality of stirring frames 33 are connected. The upper end surface of the inner ring 24 is higher than the upper end surface of the outer ring 28, and the lower end surface of the rotating frame 31 is higher than the upper end surface of the outer ring 28. The material is added into the processing barrel 21 from the gap between the upper end surfaces of the rotating frame 31 and the outer ring 28 for reaction, and the rotating frame 31 is driven to rotate, and the rotating frame 31 drives the multiple stirring racks 33 to rotate. The multiple stirring racks 33 push the material in the processing barrel 21 to move when they rotate. The upper parts of the multiple stirring racks 33 are vertical hollow blades, and the lower parts are spiral blades. When they rotate, they can apply thrust to the material in the vertical and horizontal directions, thereby pushing the material to move in the circumferential and vertical directions, thereby accelerating the reaction process of the material and accelerating the processing speed of the water reducer. The connecting pipe 32 is connected to the externally arranged heating furnace, so that the connecting pipe 32 is connected to the externally arranged heating furnace. High-temperature steam is supplied inside, and the high-temperature steam flows into the multiple stirring racks 33 through the rotating frame 31. The high-temperature steam can be supplied to the connecting pipe 32 through an externally arranged heating furnace, and the high-temperature steam can be sucked back and supplied again to ensure the temperature of the high-temperature steam. Another connecting pipe 32 can be arranged on the rotating frame 31 to communicate with the externally arranged heating furnace as a channel for the high-temperature steam to circulate back to the externally arranged heating furnace. As the multiple stirring racks 33 rotate, the materials are quickly pushed and heated at the same time, thereby realizing the rapid reaction of the materials and processing the water reducer. The two arc frames 22 can also be driven to slide, and the two arc frames 22 drive the processing barrel 21 to swing, thereby realizing the shaking of the materials in the processing barrel 21, further accelerating the movement of the materials, and accelerating the reaction of the materials.

[0031] refer to Figure 6 and 10 , detailed description of the embodiment of fully dispersed material mixing:

[0032] The processing barrel 21 is spherical on the outside and spherical on the inside. The space in the middle of the two spheres is easier to stir than the barrel-shaped space and the rectangular space. In the process of material movement, the moving materials can collide with each other in the circumferential and vertical directions through the characteristics of different diameters, so that the collision of the materials during reaction is more intense, and the vortex generated when the barrel-shaped space mixes the materials and the dead corner generated when the rectangular space mixes the materials can be prevented. The materials can move faster and more smoothly, and the materials can be more fully dispersed, thereby accelerating the reaction speed of the materials. The multiple hollow stirring racks 33 can heat the materials from the inside of the material accumulation while promoting the movement of the materials for mixing and reaction, and quickly adjust the temperature of the materials. The spherical space in the middle of the processing barrel 21 can make the heating ball 51 set in the middle of the processing barrel 21 fully contact with the middle of the processing barrel 21, and can exchange heat with the materials in the processing barrel 21 over a larger area. The high-temperature steam flowing in the multiple stirring racks 33 can exchange heat with the materials, and the temperature of the materials can be quickly adjusted, thereby quickly heating and cooling the materials, thereby accelerating the reaction speed and reaction process of the materials. The middle part of the processing barrel 21 is a spherical space, so that the materials can be fully dispersed, so that the materials can react quickly and evenly after being fully dispersed, thereby accelerating the processing speed of the water reducing agent.

[0033] refer to Figure 1 , 2 , 3 and 4, detailed description of the embodiment of the swing support processing barrel 21:

[0034] Two brackets 13 supporting the processing barrel 21 are fixedly connected to the base frame 11, so that when the two arc frames 22 are driven to slide and the processing barrel 21 is driven to swing, the stable movement of the processing barrel 21 can be ensured, and the two arc frames 22 can be prevented from getting stuck when sliding, thereby affecting the movement of the processing barrel 21.

[0035] refer to Figure 1 , 2 , 3, 4 and 5, detailed description of the embodiment of driving the processing barrel 21 to swing:

[0036] The two arc frames 22 are fixedly connected with racks 23, and each slideway 12 is rotatably connected with a gear Ⅰ14 that meshes and drives the corresponding rack 23 to slide. Each slideway 12 is fixedly connected with a reduction motor Ⅰ that drives the corresponding gear Ⅰ14 to rotate. The two reduction motors Ⅰ are both provided with brakes. When the two reduction motors Ⅰ are started, the two gears Ⅰ14 are synchronously driven to rotate. The two gears Ⅰ14 rotate and mesh to drive the two racks 23 to slide. The two racks 23 are both arc racks, and the center of the circle coincides with the center of the circle of the processing barrel 21, so that the two racks 23 can drive the two arc frames 22 to slide, and then drive the processing barrel 21 to swing, so as to achieve full reaction of the movement and mixing of the materials in the processing barrel 21, and the brakes provided on the two reduction motors Ⅰ can drive the gear Ⅰ14 to be fixed, so as to ensure the fixed position of the processing barrel 21.

[0037] refer to Figure 5 , 6 , 7 and 8, detailed description of the embodiment of driving the rotary frame 31 to rotate:

[0038] The rotating frame 31 is fixedly connected with a gear rack 34, and the inner wall of the inner ring 24 is rotatably connected with a gear II 35 for driving the gear rack 34 to rotate. The gear II 35 is fixedly connected to the output shaft of the reduction motor II, and the reduction motor II is fixedly connected to the inner ring 24. When the reduction motor II is started, the reduction motor II drives the gear II 35 to rotate, and the gear II 35 meshes with the driving gear rack 34 to rotate, thereby driving the rotating frame 31 to rotate, thereby realizing the rotation of multiple stirring racks 33 and achieving rapid mixing of materials.

[0039] refer to Fig. 9 , the embodiment of the sealing processing barrel 21 is described in detail:

[0040] The processing barrel 21 is fixedly connected with a plurality of cylinders Ⅰ41, and a sealing sleeve 42 is fixedly connected with the cylinder rods of the plurality of cylinders Ⅰ41, and the sealing sleeve 42 is coupled with the outer ring 28 and the rotating frame 31. Therefore, when adding materials, the plurality of cylinders Ⅰ41 are started, and the cylinder rods of the plurality of cylinders Ⅰ41 drive the sealing sleeve 42 to rise and fall, so that the gap between the upper end surface of the rotating frame 31 and the outer ring 28 is exposed, thereby losing the seal for adding materials. After the adding is completed, the plurality of cylinders Ⅰ41 are started again, and the plurality of cylinders Ⅰ41 drive the plurality of sealing sleeves 42 to reset, and the sealing sleeve 42 is coupled with the outer ring 28 and the rotating frame 31, so as to realize the sealing of the processing barrel 21, prevent the leakage of materials, and make full use of the temperature.

[0041] refer to Figure 4 , describe in detail the embodiment of blanking:

[0042] The lower part of the processing barrel 21 is provided with a feeding pipe 26, and a plug rod 27 is threadedly connected to the feeding pipe 26. Therefore, when feeding, the processing barrel 21 is driven to swing until the feeding pipe 26 is vertically downward, so that the plug rod 27 is removed to feed the water reducing agent.

[0043] refer to Figure 1 , an embodiment of heating the material from the middle of the processing barrel 21 is described in detail:

[0044] A heating ball 51 is fixedly connected to the middle of the processing barrel 21. The heating ball 51 is connected to an externally arranged heating furnace, so that high-temperature steam is circulated and supplied to the heating ball 51 through the externally arranged heating furnace, thereby satisfying the heating function of the heating ball 51 on the material, further heating the dispersed material from multiple directions, quickly controlling the temperature of the material, and accelerating the reaction speed of the material. High-temperature steam can be supplied to the heating ball 51, high-temperature steam can be sucked back, and high-temperature steam can be supplied again to ensure the temperature of the high-temperature steam. Another branch pipe can also be set on the heating ball 51 to communicate with the external heating furnace as a channel for the high-temperature steam to circulate back to the external heating furnace to ensure the heat in the heating ball 51. The two reduction motors I synchronously drive the two gears I14 to rotate. The two gears I14 rotate and mesh to drive the two racks 23 to slide. The two racks 23 are both arc-shaped racks. The center of the two racks 23 coincides with the center of the processing barrel 21, so that the two racks 23 can drive the two arc-shaped racks 22 to slide, and then drive the processing barrel 21 to swing. When the processing barrel 21 swings, the inner and outer spheres can drive the internal materials to shake, thereby destroying the vortex formed when the multiple stirring racks 33 rotate to drive the material to move, and can quickly move the material through During the mixing process, the processing barrel 21 is disturbed by the swing of the processing barrel 21, and the frequency of material collision is increased. The reciprocating swing of the processing barrel 21 prevents the material from forming a balance again when adapting to the rotation of the processing barrel 21 in one direction, so that the material is in an entropy increase state for a long time, and the mixing speed and reaction speed of the material are accelerated. While promoting the movement of the material for mixing and reaction, the plurality of hollow stirring racks 33 are used to heat the material from the inside of the material accumulation, and the temperature of the material is quickly adjusted. The heating ball 51 in the spherical space in the middle of the processing barrel 21 is in full contact with the middle part of the processing barrel 21, and can exchange heat with the material in the processing barrel 21 over a larger area, and can quickly make the high-temperature steam exchange heat with the material, quickly adjust the temperature of the material, and force the entropy increase state to intensify when the material is mixed, so that the material reaction is more intense, thereby quickly realizing the reaction of the material and completing the preparation of the concrete water reducer.

[0046] According to the above-mentioned concrete water reducing agent processing device, the processing technology of the concrete water reducing agent includes the following steps:
