DETAILED DESCRIPTION

[0027] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0028] See attached Figure 1-2 As shown, a cement-based slurry rapid production slurry mixing device includes a slurry mixing barrel 1, a rotating plate 4 is pivotally connected to the bottom of the slurry mixing barrel 1, and partitions 5 are arranged on the rotating plate 4 to divide the interior into areas of different volumes for placing different amounts of cement-based slurry raw materials. The slurry mixing barrel 1 is covered with a cover plate 2, and a motor 3 is installed in the middle of the cover plate 2. The output end of the motor 3 is connected to the rotating plate 4 through a rotating rod to drive the rotation.

[0029] The rotating plate 4 is provided with feeding openings 7 of different sizes between two adjacent partitions 5, and the periphery of the feeding opening 7 forms an inward depression, forming a drop opening 6 with a larger top and a smaller bottom, which is convenient for the raw materials to fall. However, since the rotating plate 4 needs to rotate, there is a certain gap between it and the bottom of the inner wall of the slurry mixing barrel 1, and fine particles of raw materials are easily caused to fall into the gap during the rotating feeding process, resulting in the problem of rotation blockage.

[0030] Therefore, if the attached Figure 3 As shown, a flap 20 is hinged downward on one side of the inner wall of the corresponding discharge port 7, and a through slot is provided at the bottom of the slurry mixing barrel 1 along the lower part of the rotation path of the rotating plate 4. The raw materials gradually fall down during the period when the flap 20 rotates with the rotating plate 4 into the through slot until it is completely vertical; when it rotates in the same direction later, the flap 20 gradually starts to rotate upward to close the discharge port 7. The arrangement of the flap 20 can block the raw materials of fine particles falling into the gap, so as to avoid the rotation blockage problem of the rotating plate 4.

[0031] The size of the through slot is larger than the sizes of all the feeding openings 7, so that the flip block 20 can gradually descend to a vertical state when the rotating plate 4 rotates to the position of the through slot.

[0032] Regarding the problem of initial blockage in material discharge: since the size of the discharge port 7 is not easy to be set too large, the raw materials between the discharge port 7 and the through slot will be blocked or even blocked when the particles are small. The solution of this scheme is to drive the rotating plate 4 to continue to rotate forward by a small angle through the motor 3, drive the flip block 20 to turn upward and then reverse to restore the corresponding angle, so that the raw materials are repeatedly pounded at the discharge port 7, and there is no need to use external mechanical or motorized structure for pounding, so the material discharge can be prevented from being blocked quickly and conveniently.

[0033] Conventionally, multiple raw material proportioning must be performed in advance before the material is discharged through the discharge port 7, which is relatively more complicated and has a low control of the progress. In this embodiment, a proportioning mechanism is directly arranged under the slurry mixing barrel 1, and the preset raw material weight is transferred and gathered to the preset weight before falling to the discharge port 10, so as to realize automatic and accurate proportioning, and the proportioning can be repeated multiple times.

[0034] A hollow area is formed below the slurry mixing barrel 1, and a batching mechanism is provided. The batching mechanism includes a balancing base 11 located in the middle, and a long strip-shaped mixing frame 15 is hinged on the balancing base 11, so that the mixing frame 15 can be individually deflected to both sides based on the balancing base 11. Upward extending protrusions are formed on both sides of the mixing frame 15 to prevent the raw materials from falling out to the side. One end of the mixing frame 15 is connected to a drop hopper 13, which is located between the upper through groove and the lower discharge port 10, serving as a transfer position for the raw materials. A cylinder 12 is provided below the other end of the mixing frame 15, and the balancing base 11 is actively driven by the cylinder 12 to complete the deflection, that is, a weighing module / weighing sensor is provided in the drop hopper 13, and when the raw materials gathered inside reach a preset weight, the drop hopper 13 is lifted up to deflect downward to achieve drop.

[0035] See attached Figure 4-5 As shown, a hinged door panel 18 is provided at the rear side of the drop hopper 13, and the drop hopper 13 is turned outward and opened during the rotation of the mixing frame 15 to realize the downward drop of materials. In order to prevent the raw materials from deviating from the discharge port 10 and falling onto the base 8, a semi-enclosed convergence frame 14 is provided near the base 8 at the drop chute 17, so that the raw materials falling out of the door panel 18 can fall into the drop chute 17 with the help of the convergence frame 14. It should be noted that the drop chute 17 is in a cone shape with a larger upper part and a smaller lower part, and the size of its lower side is consistent with the size of the discharge port 10.

[0036] As a quality control unit, the batching mechanism uses active compensation for the difference in raw material quantity to improve the progress of slurry proportioning. Specifically, a large notch 25 is provided on one side of the inner side of the drop hopper 13, and an inward sealing block 1 23 is hingedly connected, and a small notch 26 is provided on the other side, and an outward sealing block 2 24 is hingedly connected. When the weight of the raw materials in the drop hopper 13 is too large, it can be deflected inward so that the raw materials fall out of the large notch 25 for mixing. Considering that there is a situation where the raw materials fall out in excess of the preset weight, it can be deflected outward so that the raw materials on the mixing frame 15 return to the drop hopper 13 again to balance to the preset weight.

[0037] See attached Figure 6 As shown, further, a baffle 22 is provided near the inner side of the drop hopper 13 to prevent the raw materials from being excessively moved to the other side of the mixing frame 15 (relatively far from the drop hopper 13) after deflection, so as to form a short-term obstruction for subsequent weight mixing. The outer side of the baffle 22 is inclined to reduce the problem of raw materials being obstructed and gathered outside the baffle 22.

[0038] Considering that when the hopper 13 rotates downward for weight compensation, the outer door panel 18 will also slightly flip outward, therefore, it is necessary to set a magnet with different magnetic properties at the junction of the door panel 18 and the hopper 13. Because the deflection degree is small, the setting of the magnet can overcome this problem to a certain extent.

[0039] Of course, the magnet may not be provided, but only a large notch 25 is provided and an inwardly hinged sealing block 1 23 is provided, the design of the small notch 26 and the sealing block 2 24 is cancelled, and the weight compensation method is changed to a secondary drop compensation from the upper discharge port 7.

[0040] Secondly, after one raw material is weighed, other raw materials need to be weighed. Therefore, the raw materials remaining on the mixing frame 15 will affect the subsequent precise proportioning. In this embodiment, a recovery groove 16 is opened on the mixing frame 15 near the balancing base 11. After the last raw material proportioning is completed, the participating raw materials are deflected to fall out of the recovery groove 16. Of course, a recovery area 19 can be set on the base 8 for secondary recovery and collection of excess raw materials.

[0041] The specific embodiments described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
