Description

Technical Field

[0002] Fireproof coating stirring refers to the process of making various components of fireproof coating, such as base materials, flame retardants and additives, fully mixed evenly by mechanical or manual means. In the production of steel structure fireproof coating, generally, the fireproof coating is stirred during the preparation and blending of fireproof coating, after the fireproof coating is stored for a long time, and before preparing to apply the coating on the steel structure, so as to ensure that the quality and performance of the coating meet relevant standards and requirements, and a corresponding stirring device is required during this period.

[0003] The utility model with the existing authorized announcement number CN212975001 U discloses an automatic mixing device for producing steel structure fireproof coating. Although a mixing mechanism is composed of a driving motor, a rotating rod, several connecting rods, a connecting groove, a gear ring, several stirring rods and gears, the stirring rods can rotate around the connecting rods while rotating around the rotating rod, so that the stirring and mixing are more uniform, the effect is better, and the mixing efficiency is high.

[0004] Although the above technical solution makes the stirring and mixing more uniform and has a high mixing efficiency, the above technical solution lacks a special discharging structure. Therefore, a separate external extraction mechanism is required during discharging, and there is no intelligent discharging structure that can flexibly control the discharging flow rate and velocity, resulting in the inability to control the discharging speed during discharging of the stirred fireproof coating, thus unable to ensure the discharging stability, and unable to control the total amount of materials discharged at one time, which is likely to cause insufficient material discharge or waste. Therefore, those skilled in the art provide a stirring device for producing steel structure fireproof coating to solve the problems raised in the above background technique. Content of the Utility Model

[0005] In view of this, it is necessary to provide a stirring device for producing steel structure fireproof coating to solve the problems that the discharging speed of the stirred fireproof coating cannot be controlled during discharging, thus unable to ensure the discharging stability, and the total amount of materials discharged at one time cannot be controlled, which is likely to cause insufficient material discharge or waste.

Specific embodiments

[0024] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0025] Please refer to Figures 1 to 6 , the present utility model provides a stirring device for the production of steel structure fireproof coatings, including a stirring cylinder 1, an extension plate 2 is fixedly connected to the outer surface of the stirring cylinder 1, a stirring mechanism 3 is fixedly connected to the inner wall of the stirring cylinder 1, a button controller 4 is fixedly connected to the outer surface of the stirring cylinder 1, a discharge pipe 5 is fixedly communicated with the bottom end of the stirring cylinder 1, a flowmeter 6 is fixedly communicated with the bottom end of the discharge pipe 5, the output end of the flowmeter 6 is fixedly communicated with a first connecting pipe 7, one end of the first connecting pipe 7 away from the flowmeter 6 is fixedly communicated with a corrosion-resistant solenoid valve 8, the output end of the corrosion-resistant solenoid valve 8 is fixedly communicated with a second connecting pipe 9, the bottom end of the second connecting pipe 9 is fixedly communicated with a speed regulation cylinder 10, an electric telescopic rod 12 is fixedly connected to the inner wall of the speed regulation cylinder 10, a columnar flow-blocking block 13 is fixedly connected to the telescopic end of the electric telescopic rod 12, and a discharge pipe 11 is fixedly communicated with the bottom end of the speed regulation cylinder 10.

[0026] The operation button controller 4 can control the stirring mechanism 3 to stir the fireproof coating raw materials stored in the mixing drum 1. The operation button controller 4 can control the corrosion-resistant solenoid valve 8 to be energized to connect the first connecting pipe 7 and the second connecting pipe 9, so as to facilitate the discharged fireproof coating in the mixing drum 1 to be discharged outside through the discharge pipe 11. The flowmeter 6 can measure the discharge amount each time. When the preset discharge amount of the button controller 4 is reached, the button controller 4 can automatically control the corrosion-resistant solenoid valve 8 to disconnect the connection between the first connecting pipe 7 and the second connecting pipe 9, so as to achieve the effect of accurately controlling the discharge amount. The operation button controller 4 can control the electric telescopic rod 12 to be energized to expand and contract to control the position of the columnar flow blocking block 13 in the speed regulating cylinder 10, so as to realize the blocking ratio of the speed regulating cylinder 10, and thus achieve the effect of controlling the discharge flow rate, playing a role in flexibly controlling the single discharge flow rate and flow velocity.

[0027] Further, the outer surface of the columnar flow blocking block 13 is in contact with the inner wall of the speed regulating cylinder 10. The stirring mechanism 3, the flowmeter 6, the corrosion-resistant solenoid valve 8 and the electric telescopic rod 12 are all electrically connected to the button controller 4 through wires. Two sets of support columns 14 are fixedly connected to the bottom surface of the expansion board 2. Two support seats 15 are fixedly connected to the bottom end of each set of support columns 14. By providing the support columns 14, the expansion board 2 and the mixing drum 1 can be lifted, so as to leave a structure related to discharging below the mixing drum 1. By providing the support seats 15, the contact area between the bottom end of the support column 14 and the ground or other supporting surfaces can be increased, and thus the supporting stability of the support column 14 for the structure above it can be increased.

[0028] Further, two connecting supports 16 are fixedly connected to both side surfaces of the expansion board 2. A pull rod 17 is fixedly connected to the inner wall of each connecting support 16. By providing the pull rod 17, a rotation base surface can be provided for the hanging structure in the connecting support 16, and thus the use flexibility of the hanging structure can be increased. By providing the connecting supports 16 and the pull rod 17, they can cooperate with the above-mentioned hanging structure to lift and carry the entire stirring device.

[0029] Further, a handle 18 is provided inside each connecting support 16. The inner wall of each handle 18 is rotatably connected to the outer surface of the pull rod 17. By providing the handle 18, it can rotate around the outer surface of the pull rod 17 inside the connecting support 16, and thus it is convenient to carry the entire stirring device after being held by hand or lifted by an active suspension mechanism such as a crane.

[0030] Furthermore, a dust-proof plug 19 is clamped inside the mixing drum 1. A number of identical ventilation cavities 20 are formed inside the dust-proof plug 19. By providing the dust-proof plug 19, it is possible to prevent other external impurities from entering the mixing drum 1 through the feed inlet at the top of the mixing drum 1. At the same time, by providing the ventilation cavities 20, the inside and outside of the mixing drum 1 can be communicated, thereby increasing the air pressure balance inside and outside the mixing drum 1 during discharging, and thus increasing the discharging smoothness of the mixing device.

[0031] Furthermore, two limiting sliders 21 are fixedly connected to the outer surface of the columnar flow-blocking block 13. The outer surface of each limiting slider 21 is slidably connected to the inside of the speed-regulating cylinder 10. By providing the limiting sliders 21, they can slide stably back and forth inside the speed-regulating cylinder 10, thereby increasing the sliding stability and orientation of the columnar flow-blocking block 13 inside the speed-regulating cylinder 10.

[0032] Furthermore, an elastic sealing ring 22 is fixedly connected to the inner wall of the columnar flow-blocking block 13. The outer surface of the elastic sealing ring 22 is in contact with the inner wall of the speed-regulating cylinder 10. By providing the elastic sealing ring 22, it can be padded between the columnar flow-blocking block 13 and the speed-regulating cylinder 10, and the elastic sealing ring 22 itself has good elasticity and wear resistance, so as to prevent the fireproof coating discharged downward inside the speed-regulating cylinder 10 from infecting the electric telescopic rod 12 to a certain extent, achieving the purpose of protecting the electric telescopic rod 12.

[0033] Furthermore, an anti-slip sleeve 23 is fixedly connected to the outer surface of the discharge pipe 11. Four anti-slip convex rings 24 are fixedly connected to the outer surface of the anti-slip sleeve 23. By providing the anti-slip convex rings 24, the friction on the outer surface of the anti-slip sleeve 23 can be increased. Then, the anti-slip sleeve 23 and the anti-slip convex rings 24 can jointly increase the friction on the outer surface of the discharge pipe 11, thereby increasing the connection stability of the external hose connected to the discharge pipe 11 and the leak-proofness at the connection.

[0034] Working principle: When in use, pull out the dust-proof plug 19 from inside the mixing drum 1 and put a sufficient amount of fireproof coating to be mixed or raw materials for manufacturing the fireproof coating into the mixing drum 1 through the feeding port at the top of the mixing drum 1. Fix and connect the discharge pipe 11 with an external hose. Then, operate the button controller 4 to control the mixing mechanism 3 to mix the materials stored in the mixing drum 1. When it is necessary to discharge the materials in the mixing drum 1, operate the button controller 4 to control the corrosion-resistant solenoid valve 8 to be energized to connect the first connecting pipe 7 and the second connecting pipe 9. Thus, the well-mixed materials in the mixing drum 1 are finally discharged outside through the discharge pipe 11. When the discharge amount measured by the flow meter 6 reaches the preset discharge amount of the button controller 4, the button controller 4 automatically controls the corrosion-resistant solenoid valve 8 to disconnect the connection between the first connecting pipe 7 and the second connecting pipe 9, so as to achieve the effect of accurately controlling the discharge amount. When it is necessary to adjust the discharge flow rate, operate the button controller 4 to control the electric telescopic rod 12 to be energized for telescoping to control the position of the columnar flow-blocking block 13 in the speed-regulating cylinder 10, and then realize the blocking ratio of the speed-regulating cylinder 10, so as to achieve the effect of controlling the discharge flow rate, playing a role in flexibly controlling the single discharge flow rate and flow velocity. The design of the entire mixing device for steel structure fireproof coating production effectively solves the problems that due to the lack of an intelligent discharge structure capable of flexibly controlling the discharge flow rate and flow velocity, the speed of the fireproof coating during discharge cannot be controlled, resulting in the inability to ensure the discharge stability, and the total amount of materials discharged at one time cannot be controlled, easily leading to insufficient discharge or waste of materials.
