Description

Technical Field

[0001] This invention relates to the field of cement-based slurry production technology, specifically a rapid cement-based slurry production and mixing device. Background Technology

[0002] The performance of the grouting material directly determines the effectiveness of grouting for seepage prevention in earth-rock dams. The raw materials selected are silicate cement, fly ash, bentonite, and inorganic fibers. These cement-based grouting raw materials require strict proportioning during mixing to produce qualified cement products.

[0003] Conventional automatic batching devices often experience outlet blockages during the feeding process, hindering long-term batching operations. Furthermore, they cannot accurately batch multiple materials simultaneously, resulting in low yield rates. This case was developed to address these issues. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a rapid cement-based slurry production and mixing device, which solves the problems mentioned in the background section.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a cement-based slurry rapid production mixing device, comprising a mixing tank, a discharge port at the bottom of the mixing tank, a rotating plate pivotally connected to the bottom of the mixing tank, partitions spaced apart on the rotating plate to divide the interior into regions of different volumes, discharge ports of different sizes opened between two adjacent partitions on the rotating plate, a through groove opened at the bottom of the mixing tank along the rotation path of the rotating plate, the size of the through groove being larger than the size of all discharge ports, a hollow area formed at the bottom of the mixing tank, and a batching mechanism provided therein, the batching mechanism having a weighing module that transfers and gathers a preset weight of raw materials to a preset weight before dropping them to the discharge port to complete the batching.

[0008] As a preferred embodiment, the periphery of the discharge port forms an inward depression, resulting in a discharge port that is wider at the top and narrower at the bottom.

[0009] As a preferred embodiment, the inner wall of the feed inlet is further hinged downwards to a flapping block, and a through groove is opened below the bottom of the mixing tank along the rotation path of the rotating plate. The raw material falls and is transferred as the flapping block rotates into the through groove until it is completely vertical.

[0010] As a preferred embodiment, the batching mechanism further includes a balancing base located in the middle, which is placed on a base arranged below the mixing tank. A long strip-shaped mixing frame is hinged to the balancing base, one end of which is connected to a discharge hopper. The discharge hopper is located between the upper through slot and the lower outlet, serving as a transfer point for raw materials. A cylinder is provided below the other end, which actively drives the balancing base to deflect. A door panel is provided on the rear side of the discharge hopper.

[0011] As a preferred embodiment, the two sides of the adjustment frame further form upwardly extending protrusions.

[0012] As a preferred embodiment, the base is further provided with a semi-enclosed converging frame near the feeding trough, and the base forms a feeding trough with a cone shape that is larger at the top and smaller at the bottom within the converging frame, and the lower dimension of the feeding trough is consistent with the dimension of the discharge port.

[0013] As a preferred embodiment, the inner side of the hopper is further provided with a large slot on one side and hinged to an inward sealing block 1, and a small slot on the other side and hinged to an outward sealing block 2, wherein the size of the large slot is larger than the size of the small slot, and magnets with opposite magnetic properties are provided at the joint between the door panel and the hopper.

[0014] As a preferred embodiment, the inner side of the hopper is provided with a baffle, and the outer side of the baffle forms a beveled surface.

[0015] As a preferred embodiment, the distribution frame is further provided with a recycling trough near the balancing base, and a recycling area is provided on the base.

[0016] (III) Beneficial Effects

[0017] By adopting the above technical solution, the cement-based slurry rapid production and mixing device provided by the present invention has the following beneficial effects compared with the prior art:

[0018] 1. A downward-hinged flapper is installed on one side of the inner wall of the corresponding feed inlet, and a through groove is opened at the bottom of the mixing tank along the rotation path of the rotating plate. As the flapper rotates into the through groove and becomes completely vertical, the raw material gradually falls. The rotating plate is driven by a motor to continue rotating forward by a small angle, causing the flapper to be flipped upward and then rotated in the opposite direction to return to the corresponding angle. This process is repeated to agitate the raw material at the feed inlet. Without the need for external mechanical or electric structures for agitation, the feeding can be quickly and conveniently prevented from blocking.

[0019] 2. A batching mechanism is set up as a quality control unit, which actively compensates for the difference in raw material quantity to improve the progress of slurry mixing. Specifically, a large slot is opened on one side of the inner side of the hopper and hinged with an inward sealing block 1. A small slot is opened on the other side and hinged with an outward sealing block 2. When the weight of the raw material in the hopper is too large, it can be deflected inward to allow the raw material to fall out of the large slot for mixing. Secondly, it can be deflected outward to allow the raw material on the mixing frame to return to the hopper to balance to the preset weight. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0028] See appendix Figures 1-2 As shown, a rapid cement-based slurry production mixing device includes a mixing tank 1. A rotating plate 4 is pivotally connected to the bottom of the mixing tank 1. Partitions 5 are spaced apart on the rotating plate 4 to divide the interior into areas of different volumes for holding different amounts of cement-based slurry raw materials. The mixing tank 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 it to rotate.

[0029] The rotating plate 4 has discharge ports 7 of different sizes located between two adjacent partitions 5. The periphery of the discharge port 7 forms an inward depression, with a drop opening 6 that is larger at the top and smaller at the bottom, which facilitates the dropping of raw materials. 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 mixing tank 1. During the rotating feeding process, fine particles of raw materials can easily fall into this gap, causing rotational blockage problems.

[0030] Therefore, as attached Figure 3 As shown, a hinged flap 20 is hinged downwards on one side of the inner wall of the corresponding feed inlet 7, and a through groove is opened below the bottom of the mixing tank 1 along the rotation path of the rotating plate 4. This allows the raw material to gradually fall as the flap 20 rotates into the through groove and becomes completely vertical. When the rotating plate 4 rotates in the same direction again, the flap 20 gradually begins to rotate upwards until the feed inlet 7 is closed. The flap 20 effectively prevents fine particles from falling into the gap, thus avoiding rotational obstruction of the rotating plate 4.

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

[0032] Regarding the initial material discharge blockage issue: Due to the difficulty in setting the size of the discharge port 7 too large, the material between the discharge port 7 and the through channel may experience stagnation or even blockage when the particles are small. The solution in this plan is to drive the rotating plate 4 to continue rotating forward at a small angle by the motor 3, which will cause the flip block 20 to rotate upward and then rotate in the opposite direction to restore the corresponding angle. This process is repeated to agitate the material at the discharge port 7. Without the need for external mechanical or electric structures to agitate the material, the blockage prevention of material discharge can be achieved quickly and conveniently.

[0033] Conventionally, feeding through the discharge port 7 requires multiple raw material proportions to be prepared in advance before feeding, which is relatively more complex and has lower progress control. In this embodiment, a batching mechanism is set directly below the mixing tank 1, and the preset weight of raw materials is transferred and gathered to the preset weight before falling to the discharge port 10, realizing automated and precise batching, and can be repeated multiple times.

[0034] A hollow area is formed at the bottom of the mixing tank 1, and a batching mechanism is provided. This batching mechanism includes a balance base 11 located in the middle, and a long strip-shaped mixing frame 15 is hinged to the balance base 11, allowing the mixing frame 15 to deflect independently to both sides with the balance base 11 as a reference. The sides of the mixing frame 15 form upward-extending protrusions to prevent raw materials from falling to the side. One end of the mixing frame 15 is connected to a discharge hopper 13, which is located between the upper through-slot and the lower discharge port 10, serving as a transfer point for raw materials. A cylinder 12 is located below the other end of the mixing frame 15. The cylinder 12 actively drives the balance base 11 to deflect. A weighing module / weighing sensor is installed inside the discharge hopper 13. When the accumulated raw materials reach a preset weight, the hopper is lifted, causing the discharge hopper 13 to deflect downwards to discharge the material.

[0035] See appendix Figures 4-5 As shown, a hinged door panel 18 is provided on the rear side of the hopper 13. The hopper 13 flips open outwards as it rotates with the dispensing frame 15, allowing material to fall downwards. To prevent the raw material from deviating from the outlet 10 and falling onto the base 8, a semi-enclosed converging frame 14 is provided near the material trough 17 on the base 8, allowing the material falling from the door panel 18 to fall into the material trough 17 via the converging frame 14. It should be noted that the material trough 17 is a cone shape, wider at the top and narrower at the bottom, with its lower dimension matching the size of the outlet 10.

[0036] The batching mechanism, acting as a quality control unit, actively compensates for raw material quantity discrepancies, thereby improving the progress of slurry mixing. Specifically, a large slot 25 is provided on one side of the inner side of the hopper 13, and an inward sealing block 23 is hinged thereto. A small slot 26 is provided on the other side, and an outward sealing block 24 is hinged thereto. When the weight of the raw material in the hopper 13 is too large, it can be deflected inward to allow the raw material to fall out of the large slot 25 for mixing. Considering that the weight of the raw material falling out may exceed the preset weight, it can be deflected outward to allow the raw material on the mixing frame 15 to return to the hopper 13 to balance to the preset weight.

[0037] See appendix Figure 6 As shown, a baffle 22 is further provided near the inner side of the hopper 13 to prevent the raw material from being moved excessively to the other side of the mixing frame 15 (relatively away from the 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 material obstruction and accumulation on the outside of the baffle 22.

[0038] Considering that the outer door panel 18 will also slightly flip outward when the hopper 13 rotates downward for weight compensation, it is necessary to install magnets with different magnetic properties at the joint between the door panel 18 and the hopper 13. Since the degree of deflection is small, the installation of magnets can overcome this problem to a certain extent.

[0039] Of course, magnets can be omitted, and only a large slot 25 can be set and a sealing block 23 can be hinged inward. The design of the small slot 26 and sealing block 24 can be cancelled, and the weight compensation method can be changed to secondary drop compensation from the upper feed port 7.

[0040] Secondly, after one type of raw material is weighed, other raw materials need to be weighed in the future. Therefore, the raw materials remaining on the mixing frame 15 will affect the accurate mixing ratio in the future. In this embodiment, a recycling tank 16 is opened near the balance base 11 on the mixing frame 15. After the previous raw material mixing is completed, the participating raw materials are deflected to fall out of the recycling tank 16. Of course, a recycling area 19 can be set on the base 8 for secondary recycling and collection of excess raw materials.

[0041] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above descriptions are merely specific embodiments of the present invention and are 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 within the protection scope of the present invention.
