Description

Technical Field

[0001] The utility model relates to the technical field of stirring devices, and particularly to an efficient stirring device for castable construction. Background Art

[0002] Castable is a refractory material widely used in the high-temperature industrial field. It is used for the inner lining of equipment by casting molding to protect the equipment from high-temperature erosion. The construction quality of castable directly affects the performance of the refractory layer and the safe operation of the equipment. During the construction process, the stirring of castable is a key step, which determines the uniformity of castable and the final construction effect.

[0003] Existing castable stirring devices usually adopt mechanical stirring methods, and the mixing of materials is achieved by the rotation of stirring blades in the stirring barrel. Although this stirring method can meet the basic stirring requirements, there are certain limitations in terms of efficiency and stirring quality. The stirring efficiency is limited by the stirring speed and stirring time, while the stirring quality is affected by the design of stirring blades, stirring speed, and material properties.

[0004] Traditional stirring devices may require a long stirring time to reach the required mixing uniformity, which will significantly affect the construction progress in large-scale construction. The long-time stirring operation increases energy consumption, which not only increases costs but also does not meet the requirements of modern industry for energy conservation. Summary of the Utility Model

[0005] To solve the above technical problems, the utility model provides an efficient stirring device for castable construction.

[0006] The technical solution of the utility model is an efficient stirring device for castable construction: including a stirring outer barrel, a stirring inner barrel arranged inside the stirring outer barrel with a gap therebetween, a first stirring rod arranged in the stirring inner barrel, and a second stirring rod arranged in the gap. A bracket is erected above the center of the stirring outer barrel. A transmission rod is provided on the second stirring rod. The top of the second stirring rod is rotatably connected to one end of the transmission rod through a first gear. The other end of the transmission rod is rotatably connected to the bracket through a second gear. And a toothed ring meshing and driving with the first gear is provided on the stirring outer barrel. A third gear meshing and driving with the second gear is provided on the top of the first stirring rod.

[0007] Explanation: Through the settings of the transmission rod, the first gear, the second gear, the third gear, and the toothed ring, it helps to reduce energy loss during the stirring process, improve the transmission efficiency, increase the utilization rate of kinetic energy, and at the same time simplify the installation and maintenance process.

[0008] Furthermore, through holes communicating with the inside of the stirring outer barrel are provided on the stirring inner barrel.

[0009] Description: The stirring inner barrel is provided with through holes communicating with the inside of the stirring outer barrel, which can form a mixed flow path between the inner and outer barrels and reduce the stirring dead angle.

[0010] Further, a sliding gate for controlling the opening or closing of the through hole is provided on the through hole. A push plate capable of intermittently contacting the second stirring rod is arranged on the sliding gate, and the push plate is made of rubber material; the sliding gate is slidably connected to a track provided on the stirring inner barrel, and a return spring is arranged on one side of the track.

[0011] Description: When the second stirring rod rotates, it intermittently contacts the push plate, pushes the sliding gate to open, and compresses the return spring. When the sliding gate opens to the maximum, the rubber push plate deforms and bends under the action of force, and the second stirring rod continues to rotate over the push plate. Under the action of the return spring, the sliding gate resets and closes, realizing the intermittent opening and closing of the through hole; the intermittent opening and closing of the through hole can realize the premixing of two kinds of materials in the stirring outer barrel and the stirring inner barrel, and realize the periodic material exchange, realizing the mixing of materials in batches by quantity, avoiding the phenomena of material agglomeration, condensation or excessive heat release caused by one-time feeding and mixing, and ensuring the mixing quality of the castable.

[0012] Further, a movable ring plate is arranged at the top of the stirring outer barrel, a groove is arranged on the side wall of the stirring outer barrel, and a convex block slidably clamped with the groove is arranged on the side wall of the movable ring plate; the second stirring rod passes through the movable ring plate and is rotatably connected to the movable ring plate.

[0013] Description: The sliding clamping structure of the movable ring plate and the groove enables the movable ring plate to rotate with the rotation of the second stirring rod, preventing foreign impurities from entering, ensuring the purity of the stirred materials and avoiding material splashing.

[0014] Further, the sliding gate adopts an electrically controlled opening and closing gate.

[0015] Description: The electrically controlled opening and closing gate can, according to the consistency of the material and the needs of the stirring process, by adjusting the opening degree of the electrically controlled opening and closing gate, open and close the through hole or adjust the size of the through hole, change the hydrodynamic conditions inside the stirring inner barrel, reduce the dead zone, improve the mixing efficiency and uniformity of the material, so as to control the entry and exit or internal circulation of the material, optimize the stirring effect, and close the through hole when the material circulation is not required, which can reduce the energy loss during the stirring process.

[0016] Further, temperature sensors are arranged inside both the stirring outer barrel and the stirring inner barrel, and heating wires, refrigerating sheets and temperature controllers are arranged on the inner walls of both the stirring outer barrel and the stirring inner barrel.

[0017] Description: The temperature sensor can monitor the temperature changes of the inner and outer barrels in real time, while the heating wire and the Peltier cooler can quickly adjust the temperature according to requirements to ensure that the temperature of the material during the stirring process remains within the ideal range, which is particularly important for temperature-sensitive materials; the circulating flow stirring between the inner and outer barrels can promote the uniform mixing of the material and improve the heat transfer efficiency, effectively reducing the thermal stress caused by uneven temperature; the precise control of temperature helps to improve the fluidity and viscosity of the material, thereby improving the stirring efficiency and quality; when the through-hole is closed, independent temperature control of the inner and outer barrels can be achieved, and when the through-hole is opened for mixing, the environmental requirements of different materials can be met. The automation of the temperature controller and the stirring process reduces the difficulty and error rate of manual operation and improves the production efficiency.

[0018] The beneficial effects of the present utility model are as follows: By providing a stirring outer barrel and a stirring inner barrel, and through the meshing of the first gear and the toothed ring, the relative movement between the second stirring rod and the stirring inner barrel can be increased, and the self-rotation of the second stirring rod can be realized during the rotation process, so that the turbulent effect of the material during the stirring process is enhanced, thereby improving the mixing effect and uniformity of the material, achieving efficient mixing of the material, ensuring more sufficient stirring, and thus improving the overall mixing efficiency; Since the stirring inner barrel is provided with a through-hole communicating with the inside of the stirring outer barrel, the flow of the material in the container during the stirring process can be made more uniform, realizing the mixed flow path between the inner and outer barrels. After adding the material, the stirring dead angle is reduced and the product quality is improved. BRIEF DESCRIPTION OF THE DRAWINGS
