Description

Technical Field

[0001] The invention relates to the technical field of concrete mixing, in particular to a fiber concrete mixer. Background Art

[0002] Fiber concrete is a special type of concrete that enhances the performance of the material by adding dispersed non-directional fibers into cement paste, mortar or concrete matrix. The aggregate usually does not contain coarse aggregate and consists only of fine aggregate.

[0003] The evenly added fibers can effectively prevent the expansion of micro cracks inside the concrete and the formation of macro cracks, significantly improve the tensile, bending, impact and fatigue resistance of the concrete, and have good ductility.

[0004] At present, the main method of adding fibers is manual, which causes the fibers to clump and disperse unevenly during the mixing process of fiber concrete. At the same time, manual fiber addition takes a long time, which prolongs the mixing time of fiber concrete, resulting in a large amount of heat generated during the mixing process, which in turn causes the water in the fiber concrete to evaporate and reduce the water-cement ratio, thereby reducing the performance of the fiber concrete.

[0005] In view of this, in order to effectively solve the problems that fibers are easy to agglomerate and unevenly dispersed during the mixing process of fiber concrete, and a large amount of heat is generated during the long mixing time, causing water evaporation and reducing the water-cement ratio, a new fiber concrete mixer is proposed.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0069] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0070] First see Figure 1 , Figure 1 The fiber concrete mixer of the present invention is a schematic structural diagram of an embodiment of the present invention. As shown in the figure, the mixer includes a dry material transport device 1, a fiber dispersion and suction device 2, a static elimination device 3, a dry material mixing device 4, a baffle water inlet device 6 and a wet material mixing device 7.

[0071] The dry material transport device 1 is connected to the dry material mixing device 4, and is used to transfer the concrete dry material to the dry material mixing device 4. The fiber dispersing and suction device 2 and the static eliminator 3 can be set on the top of the dry material mixing device 4, and the fiber dispersing and suction device 2 is used to transfer the fiber to the dry material mixing device 4 after dispersing. The dry material mixing device 4 is used to mix the above-mentioned concrete dry material and fiber together, so that the fiber is evenly dispersed in the concrete dry material. The static eliminator 3 is used to blow ions into the dry material mixing device 4 to prevent the static electricity generated by the mixing from adsorbing the fiber on the inner wall of the dry material mixing device 4.

[0072] The baffle water inlet device 6 is located between the dry material mixing device 4 and the wet material mixing device 7. When the dry material mixing device 4 completes mixing, the baffle water inlet device 6 is opened to allow the evenly mixed concrete dry material and fiber to fall into the wet material mixing device 7. Afterwards, the baffle water inlet device 6 is closed, and water is injected into the wet material mixing device 7, which performs mixing to fully combine the concrete dry material, fiber and water to form fiber concrete.

[0073] See also Figure 2 And continue to read Figure 1 , Figure 2 FIG. 2 is a schematic diagram of the structure of an embodiment of the dry material transport device of the present invention. Figure 1 and Figure 2 As shown, the dry material transport device 1 can use an inclined chain plate conveyor 11. In order to prevent the dry concrete material from sliding during transportation, a blocking bar 12 can be provided on each chain plate of the chain plate conveyor 11. In this way, the blocking bar 12 prevents the dry concrete material from sliding, so that the dry concrete material can smoothly enter the dry material mixing device 4.

[0074] See also Figure 3 And continue to read Figure 1 , Figure 3 FIG. 2 is a schematic diagram of the structure of an embodiment of the fiber dispersing and suction device of the present invention. Figure 1 and Figure 3As shown, the fiber dispersing and suction device 2 includes a fiber dispersing device 21 and a centrifugal suction fan 22. The fiber dispersing device 21 may include a first power device 212, a bidirectional roller 213, a large licker-in roller 214 and a small licker-in roller 215 arranged in a first housing 211. A fiber inlet 216 is provided above the first housing 211. The first power device 212 includes a driving shaft and a driven shaft connected by a belt, and the driving shaft and the driven shaft are respectively connected to the large licker-in roller 214 and the small licker-in roller 215, and the driving shaft can be driven by a motor. The bidirectional roller 213 may include a driving wheel and a driven wheel, and the driving shaft of the first power device 212 is connected to the driving wheel of the bidirectional roller 213 through another belt. The driving wheel and the driven wheel may be connected by a gear 643, and the driving wheel and the driven wheel are driven by the driving shaft of the first power device 212 to realize relative rotation. The bidirectional roller 213 may be arranged below the fiber inlet 216.

[0075] After the fibers are put into the fiber inlet 216, the fibers are first dispersed by the bidirectional roller 213. Under the action of the relatively rotating bidirectional roller 213, the fibers can enter the fiber dispersion device 21 in an orderly manner. After that, the fibers pass through the large licker-in roller 214 and the small licker-in roller 215. Since the cone thorns of the large licker-in roller 214 are relatively large, the large fiber clusters are first processed into dispersed small clusters, and then the small clusters of fibers are processed and dispersed by the small licker-in roller 215. Since the cone thorns of the small licker-in roller 215 are small and dense, the small clusters of fibers can be quickly picked out after passing through the small licker-in roller 215, thereby achieving the purpose of dispersing the fibers. The fibers processed by the fiber dispersion device 21 are sucked into the dry material mixing equipment by the centrifugal suction fan 22.

[0076] See also Figure 5 , Figure 5 FIG. 1 is a schematic structural diagram of an embodiment of the centrifugal suction fan of the present invention. Figure 4 and Figure 5 As shown, the centrifugal suction fan 22 may include a second power device 221, a fan blade 222 and a second shell 223. The fan blade 222 may be placed in the second shell 223, and the second shell 223 is provided with a fiber outlet 224. The transmission shaft of the second power device 221 passes through the second shell 223 and is connected to the fan blade 222. The second shell 223 may be connected to the first shell 211 of the fiber dispersing device 21 through a pipeline. The fiber outlet 224 may be connected to the dry material stirring device 4. In the working state, the second power device 221 drives the fan blade 222 to rotate, thereby generating negative pressure to drag the fiber to move, so that the fiber dispersed by the fiber dispersing device 21 enters the dry material stirring device 4 from the fiber outlet 224, completing the dispersion and transmission of the fiber.

[0077] See also Figure 6 and Figure 7 , Figure 6A schematic structural diagram of an embodiment of a static eliminator of the present invention; Figure 7 FIG. 2 is a schematic diagram of the structure of another embodiment of the static elimination device of the present invention. Figure 6 and Figure 7 As shown, the above-mentioned static eliminator 3 can be arranged adjacent to the fiber dispersion and suction device 2. The static eliminator 3 can include a hair dryer 31, an ionizer 32 and an explosion-proof touch cone 33. The upper end of the explosion-proof touch cone 33 is in contact with the air ionized by the ionizer 32. The hair dryer 31 is installed on the upper end of the pipeline, and the lower end of the pipeline is connected to the dry material stirring device 4. In the assembled state, the lower end of the explosion-proof touch cone 33 is inserted into the pipeline. In the working state, the ionizer 32 ionizes the air, so that ions are generated on the surface of the explosion-proof touch cone 33. Under the action of the hair dryer 31, the above-mentioned ions can be blown into the dry material stirring system to prevent the static electricity generated by stirring from causing the fiber to be adsorbed on the inner wall of the dry material stirring device 4, thereby improving the reliability of the mixer.

[0078] See also Figure 8 , Fig. 9 and Fig.10 , Figure 8 A cross-sectional view of an embodiment of a fiber concrete mixer of the present invention; Fig. 9 It is a structural schematic diagram of an embodiment of the dry material mixer of the present invention;

[0079] Fig.10 FIG. 1 is a schematic diagram of the structure of an embodiment of the dry material stirring and cleaning device of the present invention. Figure 8 As shown, the dry material mixing device 4 may include a third housing 41, a dry material mixer 42, a dry material mixing and cleaning device 43, and a dry material mixing fixed connection frame arranged in the third housing 41. A dry material inlet 411 is provided on the third housing 41, and the dry material inlet 411 is connected to the dry material transport device 1, so as to allow the transported concrete dry material to enter the third housing 41.

[0080] like Figure 8 and Fig. 9 As shown, the dry material mixer 42 includes a dry material mixer drive shaft 421 and two or more first spiral blades 422 fixedly arranged around the dry material mixer drive shaft 421. The installation height of each first spiral blade 422 can be adapted to the chamber height of the third housing 41. In addition, a plurality of rectangular holes 4221 are provided on each first spiral blade 422. When the dry material mixer drive shaft 421 is driven, the first spiral blade 422 can be driven to rotate.

[0081] Since the first spiral blade 422 is highly matched to the chamber of the third shell 41 and is larger than other types of mixing blades, it can provide a stronger turbulence intensity, so that the fiber and concrete dry material can circulate more widely, avoiding the disadvantage that the dry material adheres to the above shell and does not participate in the mixing, making the mixing more sufficient, thereby improving the mixing effect. The rectangular hole 4221 can enhance the shear force of the mixing and promote the flow of the concrete dry material and the fiber, so as to further break up the fiber agglomeration, make the fiber distribution more uniform, and improve the mixing effect.

[0082] like Figure 8 and Fig.10 As shown, the dry material stirring and cleaning device 43 may include a rotating shaft 431, a connecting rod 432 and an obtuse-angled scraper 433. The rotating shaft 431 is fixed to the top of the dry material mixer drive shaft 421, the obtuse-angled scraper 433 is closely attached to the inner wall of the dry material stirring device 4, and the top of the obtuse-angled scraper 433 is fixedly connected to the rotating shaft 431 through the connecting rod 432. In order to enhance the strength of the dry material stirring and cleaning device 43, another connecting rod 432 may also be provided at the bottom of the obtuse-angled scraper 433 to connect the bottom of the obtuse-angled scraper 433 with the dry material mixer drive shaft 421.

[0083] When the above-mentioned dry material mixing device 4 is mixing, the dry material mixer drive shaft 421 will drive the dry material mixing and cleaning device 43 to work, so that the obtuse scraper 433 can contact the inner wall of the third shell 41 while the dry material mixer drive shaft 421 rotates, so as to scrape the concrete dry material or fiber adhered to the inner wall, and further overcome the disadvantage of the dry material adhering to the shell and not participating in the mixing on the basis of the first spiral blade 422, so that the mixing is more sufficient.

[0084] like Figure 1 As shown, the above-mentioned dry material stirring fixed connection frame can be set to the top of the shell, and can include a bearing and a plurality of support rods 44 evenly arranged around the axis of the bearing, and the other ends of the above-mentioned plurality of support rods 44 are fixedly connected to the inner wall of the third shell 41. The above-mentioned bearing can be sleeved on the top of the rotating shaft 431, so as to limit the rotation direction of the dry material mixer drive shaft 421 on the basis of improving the overall strength of the dry material stirring device 4, thereby improving the reliability of the mixer.

[0085] Re-read Figure 8, the stirring action of the dry material stirring device 4 and the wet material stirring device 7 can be driven by the first double-shaft motor 5. The first double-shaft motor 5 is arranged between the dry material stirring device 4 and the wet material stirring device 7. The lower end of the dry material stirring machine driving shaft 421 is connected to the upper shaft of the first double-shaft motor 5. During the dry material stirring process, the upper shaft of the first double-shaft motor 5 drives the dry material stirring machine driving shaft 421 to rotate. In order to improve the sealing performance of the first double-shaft motor 5, a motor housing can be arranged outside the first double-shaft motor 5.

[0086] See next Figure 11-Figure 15 , Fig.11 It is a structural schematic diagram of an embodiment of the baffle water inlet device of the present invention; Fig.12 It is a structural schematic diagram of an embodiment of the baffle water inlet device of the present invention in a closed state; Fig.13 A schematic diagram of an embodiment of the internal structure of the baffle water inlet device of the present invention; Fig.14 It is a schematic diagram of another embodiment of the internal structure of the baffle water inlet device of the present invention; Fig.15 FIG. 2 is a schematic diagram of the structure of an embodiment of the lower baffle of the present invention. Fig.11 As shown, the baffle water inlet device 6 includes a fourth housing 61 and an upper baffle 62 and a lower baffle 63 which are arranged at the upper and lower ends of the fourth housing 61 and can be opened and closed. In the assembled state, the upper baffle 62 is located between the third housing 41 and the fourth housing 61, and the upper baffle 62 can be used as the bottom plate of the dry material mixing device 4. The lower baffle 63 is located between the fourth housing 61 and the wet material mixing device 7, and can be used as the top plate of the wet material mixing device 7.

[0087] The upper baffle 62 includes a left upper baffle 621 and a right upper baffle 622 which are hinged to each other and are semicircular. The lower baffle 63 includes a left lower baffle 631 and a right lower baffle 632 which are hinged to each other and are semicircular. During the mixing process of the dry material mixing device 4, the left upper baffle 621 and the right upper baffle 622, as well as the left lower baffle 631 and the right lower baffle 632 are tightly engaged to prevent the concrete dry material and fiber from leaking out. After the mixing of the dry material mixing device 4 is completed, the left upper baffle 621 and the right upper baffle 622, as well as the left lower baffle 631 and the right lower baffle 632 are synchronously opened around the hinge, so that the uniformly mixed concrete dry material and fiber fall into the wet material mixing device 7.

[0088] like Fig.12 and 13As shown, the upper baffle 62 and the lower baffle 63 can be closed and opened by two second dual-axis motors 641. Specifically, the two transmission shafts of one second dual-axis motor 641 can be connected to the upper left baffle 621 and the lower left baffle 631 through a transmission rod 642, and the two transmission shafts of the other second dual-axis motor 641 can be connected to the upper right baffle 622 and the lower right baffle 632 through a transmission rod 642, and the two second dual-axis motors 641 can be fixedly connected to the inner wall of the fourth housing 61.

[0089] When the upper baffle 62 and the lower baffle 63 are opened, the two second dual-axis motors 641 rotate in opposite directions, driving the upper left baffle 621 and the lower left baffle 631 to rotate leftward ( Fig.13 The second double-axis motor 641 and the transmission rod 642 are driven to rotate rightwards, thereby opening the upper baffle 62 and the lower baffle 63. In order to prevent the second double-axis motor 641 and the transmission rod 642 from being affected by the concrete dry material or fiber, a housing may be provided to enclose the second double-axis motor 641 and the transmission rod 642.

[0090] like Fig.14 As shown, the upper baffle 62 and the lower baffle 63 can also be closed and opened by a motor. Specifically, the upper left baffle 621 and the lower left baffle 631 are connected by a transmission rod 642, and the upper right baffle 622 and the lower right baffle 632 are connected by another transmission rod 642. Two meshing gears 643 can be fixedly sleeved on the two transmission rods 642. The above-mentioned motor can be fixedly arranged on the inner wall of the fourth housing 61, and the motor can drive a gear 643 to rotate the two transmission rods 642, thereby driving the upper left baffle 621 and the lower left baffle 631 to rotate to the left, and driving the upper right baffle 622 and the lower right baffle 632 to rotate to the right, so as to realize the opening of the upper baffle 62 and the lower baffle 63. Similarly, in order to prevent the motor, the gear 643 and the transmission rod 642 from being affected by the concrete dry material or fiber, a shell can also be provided to wrap them.

[0091] Re-read Fig.12 In order to ensure that the baffle water inlet device 6 is firmly connected to the dry material mixing device 4 and the wet material mixing device 7, the transmission rod 642 can extend from the upper baffle 62 and the lower baffle 63, and be rotatably connected to the third shell 41 of the dry material mixing device 4 and the fifth shell 71 of the wet material mixing device 7.

[0092] Further, refer to Fig.11 and Fig.12A support column 612 may also be fixedly provided on the fourth housing 61 on the opposite side of the transmission rod 642, and the upper and lower ends of the support column 612 are fixedly connected to the third housing 41 and the wet material mixing device 7. Correspondingly, the upper left baffle 621 and the upper right baffle 622 and the lower left baffle 631 and the lower right baffle 632 are provided with inner recesses to engage with the motor housing of the first dual-axis motor 5 and the support column 612 when closed, so as to avoid interference and form a closed joint surface to prevent leakage of concrete dry materials and fibers during the mixing process of the dry material mixing device 4.

[0093] That is to say, when the dry material mixing device 4 is mixing, the upper baffle 62 is closed to carry the concrete dry material and the fiber. In order to improve the bearing capacity of the upper baffle 62, as shown in FIG. Fig.11 As shown, a plurality of support plates 611 may be hinged in a circumferential array at the upper and lower ends of the fourth housing 61, and each support plate 611 is supported by a spring. Taking the closing of the upper baffle 62 as an example, the plurality of support plates 611 provide an upward force for the upper baffle 62 under the action of the spring, thereby supporting the upper baffle 62. The bottom of the joint surface of the upper left baffle 621 and the upper right baffle 622 may also be set to an arc shape, and each support plate 611 may be set to an arc shape, so that during the closing process of the upper baffle 62, the upper left baffle 621 and the upper right baffle 622 can press the support plate 611 downward.

[0094] Re-read Fig.12 and Fig.14 The baffle water inlet device 6 is also provided with an angle plate 651, which is used to limit the opening and closing of the upper baffle 62 and the lower baffle 63. Specifically, the upper left baffle 621 and the upper right baffle 622 are provided with a corner notch at one end close to the transmission rod 642, and when the upper baffle 62 is closed, the two corner notches form a fan-shaped notch. The above-mentioned angle plate 651 is adapted to the shape of the fan-shaped notch. A telescopic rod 652 is connected below the angle plate 651, and the fixed end of the telescopic rod 652 is fixedly connected to the inner wall of the fourth shell 61. When the dry material mixing device 4 is mixing, the telescopic rod 652 controls the angle plate 651 to move upward, so that the angle plate 651 extends into the fan-shaped notch and engages with the upper left baffle 621 and the upper right baffle 622, which can prevent the upper baffle 62 from opening during the mixing process, thereby improving the reliability of the mixer. When the upper baffle 62 needs to be opened, the telescopic rod 652 controls the angle plate 651 to move downward and disengage from the fan-shaped notch, so that the upper baffle 62 can be opened smoothly.

[0095] like Figure 1 , Figure 8 and Fig.15 As shown, the bottom of the left lower baffle 631 and the right lower baffle 632 are both provided with a plurality of first water outlets 624, and the sides of the left lower baffle 631 and the right lower baffle 632 are both provided with a first water inlet 623 ( Figure 1When the upper baffle 62 and the lower baffle 63 are opened, the mixed concrete dry material and the fiber fall into the wet material mixing device 7, and the upper baffle 62 and the lower baffle 63 are closed, and water is injected from the two first water inlets 623, so that the inlet water flows into the wet material mixing device 7 evenly from the multiple first water outlets 624.

[0096] Please review Figure 1 and Figure 8 The wet material mixing device 7 includes a fifth housing 71, a wet material mixer 72 and a wet material mixing and cooling device 73. The inner wall of the upper end of the fifth housing 71 can be provided with a plurality of second water outlets 712 around the plurality of first water outlets 624, and the fifth housing 71 is also provided with a second water inlet 711 ( Figure 1 As shown in ), the second water inlet 711 is connected with a plurality of second water outlets 712. The second water inlet 711 can be filled with water at the same time as the first water inlet 623, so that the water flows into the wet material mixing device 7 from the first water outlet 624 and the second water outlet 712 together, thereby increasing the water intake under the premise of uniform water intake, and taking away the heat generated by the mixing of the wet material mixing device 7, thereby reducing the influence of water evaporation caused by heat on the water-cement ratio.

[0097] like Figure 8 As shown, the wet material mixer 72 includes a wet material mixer drive shaft 721 and two or more second spiral blades 722 fixedly arranged around the wet material mixer drive shaft 721. The upper end of the wet material mixer drive shaft 721 is fixedly connected to the lower shaft of the first double-shaft motor 5. When the first double-shaft motor 5 drives the wet material mixer drive shaft 721, it can drive the second spiral blades 722 to rotate.

[0098] Each second spiral blade 722 can be matched with the chamber height of the fifth housing 71, and each second spiral blade 722 is provided with a plurality of elliptical holes 7221. Since the fiber concrete has low fluidity during mixing, the elliptical holes 7221 can provide stronger turbulence intensity and shear force, so that the concrete and the fiber are fully combined.

[0099] like Figure 1 As shown, a discharge port 713 may be provided on the fifth shell 71. After the fiber concrete is mixed, the discharge port 713 is opened, and the lower shaft of the first dual-shaft motor 5 rotates in reverse to discharge the finished product quickly.

[0100] See also Fig.16 and Fig.17 And re-read Figure 8 , Fig.16 It is a structural schematic diagram of an embodiment of the wet material stirring and cooling device of the present invention; Fig.17 FIG. 2 is a schematic diagram of the structure of an embodiment of the pressure pump of the present invention. Figure 8 , Fig.16 and Fig.17 As shown, the fifth housing 71 may be provided with an interlayer 714, and the lower end of the wet material mixer drive shaft 721 may extend into the interlayer 714 and be connected to the wet material mixing and cooling device 73. Specifically, the wet material mixing and cooling device 73 includes a pressure pump 731 provided at the bottom interlayer 714, the pressure pump 731 is provided with a pressure pump water inlet 7312 and a pressure pump water outlet 7313, the pressure pump water outlet 7313 is connected to a water pipe 732, and the water pipe 732 is spirally wound around the side wall of the interlayer 714. The pressure pump 731 includes a pressure pump housing 7311, a pressure pump drive shaft 7314 provided in the pressure pump housing 7311, and a pressure pump fan blade 7315 sleeved on the pressure pump drive shaft 7314. The lower end of the wet material mixer drive shaft 721 is connected to the pressure pump drive shaft 7314. In the working state, as the first dual-axis motor 5 drives the wet material mixer drive shaft 721, the pressure pump drive shaft 7314 can drive the pressure pump fan blade 7315 to rotate, thereby drawing the cooling water in the interlayer 714 into the pressure pump water inlet 7312, and flowing through the spiral water pipe 732 before being discharged, so that the cooling water can be circulated in the interlayer 714.

[0101] In this way, the wet material mixing and cooling device 73 can reduce the temperature of the fifth shell 71, further take away the heat generated by the mixing of the wet material mixer 72, and reduce the influence of water evaporation caused by heat on the water-cement ratio.

[0102] The fiber concrete mixer of the present invention can replace manual fiber dispersion operation by providing the fiber dispersion and suction device 2, and the fiber is dispersed step by step by the bidirectional roller 213, the large licker-in roller 214 and the small licker-in roller 215. Under the stirring of the dry material stirring device 4, the fiber can be evenly dispersed in the concrete dry material.

[0103] The lower baffle 63 is provided with a plurality of first water inlets 624, and the fifth shell 71 is provided with a plurality of second water inlets 711, so that water can enter the wet material mixing device 7 evenly and in large quantities, thereby reducing the influence of water evaporation caused by heat on the water-cement ratio.

[0104] Furthermore, the water pipe 732 of the wet material mixing and cooling device 73 is spirally wound around the interlayer side wall, which can reduce the temperature of the fifth shell 71, further take away the heat generated by the mixing of the wet material mixer 72, and reduce the impact of water evaporation caused by heat on the water-cement ratio.

[0105] In this way, the reliability of the fiber concrete mixer can be improved and the quality of the fiber concrete can be ensured.
