Description

Technical Field

[0001] This utility model relates to the field of limestone production technology, and in particular to a blending equipment for producing ultra-weather-resistant limestone. Background Technology

[0002] Ultra-weather-resistant limestone is made by blending high-purity calcium carbonate with functional components such as organosilicon and nano-titanium dioxide to form a dense inorganic-organic interpenetrating network. It can resist extreme corrosion such as ultraviolet rays, acid rain, and salt spray, and is widely used in outdoor cement-based products such as coastal wind power foundations and high-altitude photovoltaic supports.

[0003] Traditional blade-type mixers rely solely on the circumferential shearing of the blades, which easily causes functional powders to agglomerate into millimeter-sized lumps. This results in white spots and streaks during subsequent extrusion, requiring the machine to be stopped and manually broken up. This process is inefficient and causes dust to spill out. Furthermore, single-shaft mixing cannot simultaneously complete sieving, leading to significant color differences between batches and making it difficult to meet the stringent uniformity requirements of ultra-weather-resistant products. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a blending equipment for producing ultra-weather-resistant limestone.

[0005] This utility model is achieved using the following technical solution: a blending device for producing ultra-weather-resistant limestone, comprising a mixing chamber, a screw extruder installed at the output end of the mixing chamber, a drive motor fixedly connected to the top of the mixing chamber by bolts, a drive gear fixedly connected to the output end of the drive motor, a driven gear meshing with the surface of the drive gear, a rotating rod fixedly connected to the inner wall of the driven gear, a lever fixedly connected to the surface of the rotating rod, an annular plate fixedly connected to the inner wall of the mixing chamber, a connecting plate fixedly connected to the annular plate by a vibrating element, a flow divider fixedly connected to the inner wall of the connecting plate, a flow divider plate fixedly connected to the inner wall of the flow divider, and a trapezoidal inclined platform fixedly connected to the top of the flow divider plate.

[0006] Through the above technical solution, limestone is first screened uniformly on the diversion plate by the linkage of the lever, trapezoidal inclined platform and vibrating component, then mixed in the same compartment by the subsequent stirring rod driven by the rotating rod, and finally continuously discharged by the screw extruder.

[0007] As a further improvement to the above solution, the rotating rod passes through the bottom of the diverter cylinder, and the bottom of the diverter cylinder is located below the annular plate.

[0008] By utilizing the above technical solution, and employing a structure in which the rotating rod passes through the diverter cylinder and the bottom of the diverter cylinder is lower than the annular plate, the downward pressure of the lever on the diverter plate is directly transmitted to the vibrating component, ensuring sufficient vibration stroke and avoiding mechanical interference.

[0009] As a further improvement to the above scheme, the number of levers is set to four, and the four levers are distributed in a circumferential array with the top of the levers on the rotating rods. The distance between the trapezoidal inclined platform and the top of the diverter plate gradually increases from right to left.

[0010] Through the above technical solution, the four levers are arranged in a circular array, so that the trapezoidal inclined platform is continuously struck within a 360° range, which increases the vibration frequency of the diversion plate and improves the screening efficiency of limestone; the distance between the trapezoidal inclined platform and the top surface of the diversion plate gradually increases, ensuring that the levers apply pressure progressively and reducing instantaneous impact noise.

[0011] As a further improvement to the above solution, the vibrating element includes a sliding column, the surface of which is fitted with a spring, and a limit plate is fixedly connected to the bottom of the sliding column.

[0012] Through the above technical solution, the vibrating component composed of sliding column, spring and limiting plate compresses the spring to store energy when the diverter moves down, and releases the spring instantly after the lever is disengaged, generating high-frequency micro-amplitude vibration to prevent mesh blockage.

[0013] As a further improvement to the above solution, the number of sliding pillars is set to several, and the several sliding pillars are centrally symmetrically distributed around the bottom of the connecting plate, and the sliding pillars penetrate the bottom of the annular plate.

[0014] Through the above technical solution, several sliding columns are symmetrically arranged around the center of the connecting plate and penetrate the annular plate, so that the flow divider is subjected to uniform force in the circumference, moves up and down without jamming, and maintains synchronous vibration during long-term operation.

[0015] As a further improvement to the above solution, the upper and lower ends of the spring are respectively fixedly connected to the ends of the annular plate and the connecting plate that are close to each other.

[0016] With the above technical solution, the two ends of the spring are fixed to the annular plate and the connecting plate respectively, forming a closed force system, which prevents the spring from moving laterally, extends the service life of the spring, and ensures that the vibration direction is unidirectional and vertical.

[0017] As a further improvement to the above solution, a stirring rod is fixedly connected to the surface of the rotating rod, and a feed pipe is provided at the top of the mixing chamber.

[0018] Through the above technical solution, the rotating rod synchronously drives the stirring rod, and the stirring rod is located below the annular plate, so that the limestone can be stirred as soon as it leaves the diversion plate, shortening the mixing path and improving the mixing uniformity; the top feed pipe is separated from the stirring area to prevent the feed impact from interfering with the flow field of the screening area.

[0019] As a further improvement to the above scheme, the stirring rod is located below the annular plate.

[0020] With the above technical solution, the stirring rod is set below the annular plate. It utilizes the superposition of the kinetic energy of the naturally falling dispersed material and the rotational kinetic energy of the stirring rod to enhance turbulent mixing and reduce additional power consumption.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes a linkage structure between a trapezoidal inclined platform, a lever, and a vibrating component. During rotation, the lever first presses against the trapezoidal inclined platform, causing the diverter plate to move downwards. Then, at the moment of release, the spring rebounds, causing the diverter plate to vibrate up and down. This allows the limestone located above the diverter plate to be evenly screened through a mesh and fall into the mixing bin, achieving the beneficial effect of uniform dispersion with a single feeding and avoiding manual spreading.

[0022] This invention utilizes a synchronous rotation system consisting of a drive gear, a driven gear, a rotating rod, and a stirring rod. Simultaneously, the rotating rod drives the stirring rod to mix the dispersed materials in the bin in real time. This achieves the beneficial effects of continuously completing both dispersion and mixing processes from the same power source, shortening the process chain, and reducing energy consumption.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] Please combine Figure 1-4The ultra-weather-resistant limestone production blending equipment of this embodiment includes a mixing chamber 1. A screw extruder 2 is installed at the output end of the mixing chamber 1. A drive motor 3 is fixedly connected to the top of the mixing chamber 1 by bolts. A drive gear 4 is fixedly connected to the output end of the drive motor 3. A driven gear 5 is meshed with the surface of the drive gear 4. A rotating rod 6 is fixedly connected to the inner wall of the driven gear 5. A lever 7 is fixedly connected to the surface of the rotating rod 6. An annular plate 8 is fixedly connected to the inner wall of the mixing chamber 1. A connecting plate 9 is fixedly connected to the annular plate 8 by a vibrating element. A flow divider 10 is fixedly connected to the inner wall of the connecting plate 9. A flow divider plate 11 is fixedly connected to the inner wall of the flow divider 10. A trapezoidal inclined platform 12 is fixedly connected to the top of the flow divider plate 11.

[0027] In use, the drive motor 3 is started, causing the rotating rod 6 to drive the lever 7 to rotate. When the lever 7 rotates, the surface of the lever 7 moves the limestone located on the top of the diverter plate 11, so that it is evenly distributed on the top of the diverter plate 11. When the lever 7 contacts the trapezoidal inclined platform 12, since the distance between the trapezoidal inclined platform 12 and the bottom of the diverter plate 11 gradually increases from right to left, the diverter plate 11 will move downward when the lever 7 contacts the trapezoidal inclined platform 12. After the lever 7 disengages from the trapezoidal inclined platform 12, the lever 7 will rebound under the action of the vibrating element, causing the diverter plate 11 to sway back and forth. The limestone located above the diverter plate 11 is evenly distributed into the interior of the mixing chamber 1 through the mesh on the surface of the diverter plate 11.

[0028] The rotating rod 6 passes through the bottom of the diverter cylinder 10, and the bottom of the diverter cylinder 10 is located below the annular plate 8. By utilizing the structure of the rotating rod 6 passing through the diverter cylinder 10 and the bottom of the diverter cylinder 10 being lower than the annular plate 8, the downward pressure of the lever 7 on the diverter plate 11 is directly transmitted to the vibrating component, ensuring sufficient vibration stroke and avoiding interference between mechanisms.

[0029] There are four levers 7, which are arranged in a circular array around the top of the rotating rod 6. The distance between the trapezoidal inclined platform 12 and the top of the diversion plate 11 gradually increases from right to left. The circular array arrangement of the four levers 7 allows the trapezoidal inclined platform 12 to be continuously struck within a 360° range, which increases the vibration frequency of the diversion plate 11 and improves the limestone screening efficiency.

[0030] The vibrating component includes a slide column 13, on the surface of which a spring 14 is sleeved, and a limit plate 15 is fixedly connected to the bottom of the slide column 13.

[0031] The number of sliding pillars 13 is set to be several, and the several sliding pillars 13 are centrally symmetrically distributed around the bottom of the connecting plate 9, and the sliding pillars 13 penetrate the bottom of the annular plate 8.

[0032] The upper and lower ends of the spring 14 are fixedly connected to the ends of the annular plate 8 and the connecting plate 9 that are close to each other.

[0033] A stirring rod 16 is fixedly connected to the surface of the rotating rod 6, and a feed pipe 17 is provided at the top of the mixing chamber 1.

[0034] The stirring rod 16 is located below the annular plate 8. It utilizes the superposition of the kinetic energy of the naturally falling dispersed material and the rotational kinetic energy of the stirring rod 16 to enhance turbulent mixing and reduce additional power consumption.

[0035] The implementation principle of the blending equipment for ultra-weather-resistant limestone production in this embodiment is as follows: When blending ultra-weather-resistant limestone, the material is first fed into the mixing chamber 1, so that the limestone is located above the flow divider plate 11 inside the flow divider 10. The drive motor 3 is started, and the output end of the drive motor 3 drives the drive gear 4 to rotate. The rotation of the drive gear 4 drives the driven gear 5 to rotate. The rotation of the driven gear 5 synchronously drives the rotating rod 6 to rotate. The rotating rod 6 drives the lever 7 to rotate. When the lever 7 rotates, the surface of the lever 7 moves the limestone located at the top of the flow divider plate 11, causing it to... The limestone is evenly distributed on the top of the diverter plate 11. When the lever 7 contacts the trapezoidal inclined platform 12, the distance between the trapezoidal inclined platform 12 and the bottom of the diverter plate 11 gradually increases from right to left. Therefore, when the lever 7 contacts the trapezoidal inclined platform 12, the diverter plate 11 will move downward. After the lever 7 separates from the trapezoidal inclined platform 12, the lever 7 rebounds under the action of the vibrating element, causing the diverter plate 11 to sway back and forth up and down. The limestone located above the diverter plate 11 is evenly dispersed into the interior of the mixing chamber 1 through the mesh on the surface of the diverter plate 11, making it more uniform with the materials inside during the mixing process.

[0036] When the rotating rod 6 rotates, it synchronously drives the stirring rod 16 to rotate, so that the stirring rod 16 mixes the materials inside the mixing chamber 1.

[0037] When the diverter plate 11 moves downward, the connecting plate 9, which is fixed to the outer surface of the diverter plate 11, compresses the spring 14. At the same time, the sliding column 13 slides inside the annular plate 8. After the lever 7 disengages from the top of the trapezoidal inclined platform 12, the diverter cylinder 10 loses downward pressure, and the spring 14 rebounds, causing the diverter plate 11 to vibrate.

[0038] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
