DETAILED DESCRIPTION OF THE EMBODIMENTS
[0023] To make the objectives, technical solutions, and advantages of the present utility model clearer, the technical solutions of this application will be described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of this application and the specific features in the embodiments are detailed descriptions of the technical solutions of this application, rather than limitations on the technical solutions of this application. Without conflict, the technical features in the embodiments of this application and the embodiments can be combined with each other.
[0024] As Figure 1 , Figure 2 and Figure 3 shown, a safe and self-cleaning mixer includes a mixing pot body 9. One end above the mixing pot body 9 is provided with a feed inlet 2, and the other end below is provided with a discharge outlet 13. A mixing pot cover plate 12 is provided on the top of the mixing pot body 9. A mixing shaft 10 is provided inside the mixing pot body 9, and a plurality of mixing blades 11 for mixing materials are installed on the mixing shaft 10.
[0025] A main water pipe 3 and a side wall cleaning water pipe 4 are provided on the mixing pot body 9. One end of the main water pipe 3 is connected to a submersible pump 6, and the other end is arranged inside the mixing pot body 9 for spraying water onto the mixing shaft 10 and the mixing blades 11.
[0026] One end of the side wall cleaning water pipe 4 is connected to a self-priming pump 5, and the self-priming pump 5 starts and stops synchronously with the mixer. The water for cleaning is stirred into the finished material together with the material, saving water resources. The other end of the side wall cleaning water pipe 4 is arranged inside the mixing pot body 9 for spraying water onto the side wall of the mixing pot body 9.
[0027] In some embodiments, the main water pipe 3 is made of 1.5-inch seamless steel pipe. On the main water pipe 3 located inside the mixing pot body 9, round holes with a diameter of 6 mm are evenly opened at intervals of 5 cm. The direction of the round holes faces the mixing shaft 10 and the mixing blades 11, which is convenient for providing water to the materials being mixed while continuously flushing the mixing shaft 10 and the mixing blades 11.
[0028] In some embodiments, the side wall cleaning water pipe 4 is made of 0.5-inch seamless steel pipe. On the side wall cleaning water pipe 4 located inside the mixing pot body 9, round holes with a diameter of 1 mm are evenly opened at intervals of 5 cm. Through continuous flushing, the cement on the side wall is taken away to achieve the effect of non-sticking material on the side wall.
[0029] In some embodiments, as Figure 2 shown, the side wall cleaning water pipe 4 is installed on the side wall of the mixing pot body 9 through an L-shaped bracket 14, which is convenient for installation. The water outlet direction of the side wall cleaning water pipe 4 is perpendicular to the side wall, which is convenient for flushing the side wall.
[0030] In some embodiments, the sidewall cleaning water pipe 4 is arranged in a C shape inside the stirring pot body 9 to ensure sufficient flushing of the peripheral sidewalls of the stirring shaft 10 and the stirring blades 11, so as to achieve the effect of non-sticking of the sidewalls.
[0031] In some embodiments, the main water pipe 3 is installed at the inner top end of the stirring pot body 9, near the stirring pot cover plate 12 and arranged parallel to the stirring shaft 10, ensuring that the water discharged from the main water pipe 3 can smoothly wash the stirring shaft 10 and the stirring blades 11. The main water pipe 3 improves the stirring uniformity during the process of adding water to the materials in the stirring pot from pre-mixing to gradual increase, compared with the traditional single-point water addition.
[0032] In some embodiments, as Figure 2 、 Figure 3 shown, the main water pipe 3 is installed inside the stirring pot body 9 through the L-shaped bracket 14 and the U-shaped bracket 15, with convenient installation to ensure the normal use of the main water pipe 3. The L-shaped bracket 14 and the U-shaped bracket 15 can be welded.
[0033] In some embodiments, as Figure 1 shown, it further includes a support frame 8 installed on the stirring pot body 9. An audible and visual alarm 1 and a human presence induction sensor 7 are installed on the support frame 8. The model of the audible and visual alarm 1 can be TL-702SI / R31, and the model of the human presence induction sensor 7 can be ISE201D-2. The utility model adopts millimeter-wave radar technology. Based on the human presence induction sensor 7, it detects whether there are maintenance personnel or stirring pot cleaning personnel on the mixer. When there are people on the mixer, the audible and visual alarm 1 is triggered to give a warning to the on-site personnel and also remind the operators in the control room.
[0034] In some embodiments, as Figure 1 shown, the two support frames 8 are installed at both ends of the stirring pot body 9. An audible and visual alarm 1 is installed on one support frame 8, and a human presence induction sensor 7 is installed on the other support frame 8, with convenient installation and more accurate detection.
[0035] The usage method of the utility model is as follows:
[0036] ① The human presence induction sensor 7 and the audible and visual alarm 1 located on the support frame 8 are independently powered by a secondary power distribution cabinet supporting the equipment to which the mixer belongs. The human presence induction sensor 7 is used to detect whether there are maintenance personnel or stirring pot cleaning personnel on the mixer. When there are people on the mixer, the audible and visual alarm 1 is triggered to give a warning to the on-site personnel and also remind the operators in the control room.
[0037] ②After the equipment to which the mixer belongs operates, the feeding belt conveys materials such as crushed stones, gravels, cement, and water into the mixing pot body 9. The main water pipe 3 sprays the water from the submersible pump 6 through the round holes, providing water for the materials being mixed while continuously flushing the mixing shaft 10 and the mixing blades 11. The sidewall cleaning water pipe 4 sprays the water from the self-priming pump 5 onto the sidewall of the mixing pot body 9, and the cement on the sidewall is taken away by continuous flushing to achieve the effect of non-sticking of the sidewall.
[0038] The safety and self-cleaning mixer provided by the present utility model uses an audible and visual alarm as a continuous warning when there are people. Coupled with the function of the main water pipe installed along the mixing shaft to clean the mixing shaft, the mixing blades, and the sidewall cleaning water pipe to clean the sidewall, the effect of self-cleaning can be achieved, and the use safety of the mixer is improved.
[0039] In addition, those skilled in the art can understand that although some of the embodiments described herein include certain features contained in other embodiments rather than other features, the combinations of the features of different embodiments also mean that they are within the protection scope of the present utility model and form different embodiments. For example, in the above embodiments, those skilled in the art can use them in combination according to the known technical solutions and the technical problems to be solved by the present application.
