Description

Technical Field

[0001] The utility model belongs to the technical field of plastic processing, in particular to a stirring device for a lining repair material of a medium frequency furnace. Background Art

[0002] In the metal smelting and casting industries, medium-frequency furnaces are commonly used heating equipment. The furnace lining is a key component that protects the furnace body, preventing heat loss and molten metal penetration. Its integrity and performance are crucial to production efficiency and product quality. However, over extended use, the furnace lining may become damaged due to factors such as high temperature, erosion, or mechanical impact, necessitating repair. Plastic is a common repair material during this process. Before use, the powdered plastic needs to be stirred with water.

[0003] Traditional mixing methods often have the problem of dust flying. When adding materials to the mixing device, dust is easily generated due to the granular nature of the materials. This dust not only pollutes the working environment, but also harms the respiratory system of the operator. During the mixing process, the rotation of the agitator and the collision of materials will further generate dust. If the mixing device does not have good sealing and dust removal measures, this dust will be difficult to control. Summary of the Invention

[0004] The purpose of the utility model is to provide a medium frequency furnace lining repair material stirring device in response to the problems existing in the prior art.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a medium frequency furnace lining repair material stirring device, including a stirring barrel, and a stirrer installed on the stirring barrel, a fixed plate is installed on the stirring barrel, a cover plate is provided on one side of the fixed plate, a suction pump connected to the stirring barrel is installed on the fixed plate, the extraction end of the suction pump is connected to a suction pipe, a water pump is installed on the fixed plate, the drainage end of the water pump is connected to a water supply pipe, the other end of the water supply pipe is provided with a nozzle, and a protective cover for covering the suction pump and the water pump is installed on the fixed plate.

[0006] By adopting the above technical solution, through the effective cooperation of the suction pump and the suction pipe, and the coordinated work of subsequent auxiliary equipment, dust control and uniform mixing of materials during the plastic stirring process are achieved, providing high-quality repair materials for subsequent repair work.

[0007] Optionally, the side wall of the mixing barrel is connected to a discharge pipe, a hand valve is provided on the discharge pipe, and the discharge pipe is inclined.

[0008] By adopting the above technical solution, the discharge pipe is inclined, which facilitates the smooth discharge of the mixed material. The design of the hand valve makes the discharge process more flexible and controllable. The operator can open or close the discharge pipe at any time as needed, which improves work efficiency and operational convenience.

[0009] Optionally, the cover plate is connected to the fixed plate via the hinge, and a handle is provided on the surface of the cover plate.

[0010] By adopting the above technical solution, the hinge connection allows the cover to be easily opened and closed, which is convenient for adding materials and discharging them after stirring. The handle design provides a convenient operation method, allowing the operator to easily control the opening and closing of the cover, thereby improving the comfort and safety of operation.

[0011] Optionally, a sealing gasket is installed at one end of the cover plate close to the mixing barrel, and the sealing gasket is arc-shaped.

[0012] By adopting the above technical solution, the sealing gasket enhances the sealing between the cover and the mixing barrel, effectively preventing dust from escaping from the gap during the mixing process. The arc-shaped design enables the sealing gasket to better fit the contour of the mixing barrel, improving the sealing effect and further reducing dust pollution.

[0013] Optionally, a water inlet pipe is provided on the water supply pipe, the water inlet pipe passes through the fixed plate and extends to the inner side of the mixing barrel, and an electric control valve is provided on the water supply pipe.

[0014] By adopting the above technical solution, the water supply pipe transports the water output by the water pump to the nozzle in the mixing barrel to moisten the material and reduce dust. The water inlet pipe passes through the fixed plate and extends to the inside of the mixing barrel, ensuring direct water supply. The electric control valve realizes precise control of the water supply, which not only ensures the mixing effect but also saves water resources.

[0015] Optionally, the protective cover is cylindrical, and a heat dissipation hole is provided at one end of the protective cover away from the fixing plate.

[0016] By adopting the above technical solution, the protective cover shields and protects auxiliary equipment such as the suction pump and water pump, reducing interference and damage to the equipment caused by external factors and extending the service life of the equipment. At the same time, the protective cover also reduces the impact of noise and vibration generated during equipment operation on the surrounding environment. The design of the heat dissipation holes ensures ventilation and heat dissipation inside the protective cover, prevents failures caused by equipment overheating, and ensures stable operation of the equipment.

[0017] Optionally, the end of the suction pipe close to the suction pump is a metal pipe, and the end of the suction pipe away from the metal pipe is a metal bellows.

[0018] By adopting the above technical solution and designing the metal bellows, the length of the suction pipe can be freely adjusted.

[0019] Optionally, the lower end of the mixing barrel is provided with supporting legs, and the number of the supporting legs is several.

[0020] By adopting the above technical solution, the supporting legs ensure that the mixing barrel 1 will not shake or fall over during the mixing process, thereby ensuring the stability and safety of the mixing.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. The innovative suction tube design inserts the material bag directly into the material bag, and the material is dumped simultaneously with the suction pump. This design fundamentally blocks the direct dust emission path during the dumping process, allowing the material to enter the mixing drum in a nearly dust-free manner. Simultaneously, the water pump is activated during the dumping process, causing the nozzle to spray water into the mixing drum, further moistening and settling the small amount of dust that has been generated. This achieves comprehensive dust control from pre-mixing to the initial mixing stage, significantly improving the working environment and safeguarding the health of operators. 2. Because the material is initially concentrated and guided by the suction tube before entering the mixing drum, dispersion and uneven accumulation of the material in the mixing drum are reduced, allowing the agitator to mix the materials more efficiently and evenly. This not only improves mixing efficiency but also ensures the uniformity of the repair material, which is beneficial for improving the quality and performance of the repaired furnace lining. 3. Through effective dust control measures, dust contamination and erosion in and around the mixing device are reduced, extending the service life of the equipment and reducing equipment failure rate and maintenance costs caused by dust accumulation.

[0027] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] In the description of the present invention, it should be noted that the terms "middle", "upper", "lower", "left", "right", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0029] like Figure 1 —3 shows, the specific scheme of the embodiment is as follows: a medium frequency furnace lining repair material stirring device, including a stirring barrel 1, the stirring barrel 1 as the main part of the stirring device, mainly used to accommodate and mix plastic and the moisture required, providing a closed or semi-closed space, which is convenient for stirring and mixing materials, and reduces the overflow of dust. The lower end of the stirring barrel 1 is equipped with support legs, which ensure that the stirring barrel 1 will not shake or fall over during the stirring process, ensuring the stability and safety of the stirring. The side wall of the stirring barrel 1 is connected to a discharge pipe 101, and a hand valve 102 is provided on the discharge pipe 101. The discharge pipe 101 is inclined, and the discharge pipe 101 is used to discharge the stirred material from the stirring barrel 1; the hand valve 102 is used to control the opening and closing of the discharge pipe 101. The inclined discharge pipe 101 facilitates the smooth discharge of materials, and the design of the hand valve 102 makes the discharge process more flexible and controllable, thereby improving the operating efficiency.

[0030] And an agitator 2 installed on the mixing barrel 1, the agitator 2 includes a motor and a stirring rod installed at the output end of the motor. The motor serves as the power source of the agitator 2, driving the stirring rod to rotate. The stirring rod directly acts on the material, and the mixing and stirring of the material are achieved through rotation. The power generated by the motor is converted into mechanical movement of the stirring rod, thereby uniformly stirring the material in the mixing barrel 1. A fixed plate 3 is installed on the mixing barrel 1, and the fixed plate 3 is arc-shaped. The fixed plate 3 is connected to the mixing barrel 1 by fixing bolts.

[0031] A cover plate 4 is provided on one side of the fixing plate 3. The cover plate 4 is used to close the opening of the mixing barrel 1 to prevent dust from overflowing during the mixing process. The cover plate 4 is connected to the fixing plate 3 by the hinge 402. A handle 401 is provided on the surface of the cover plate 4. A sealing gasket 403 is installed on the end of the cover plate 4 close to the mixing barrel 1. The sealing gasket 403 is arc-shaped. The sealing gasket 403 enhances the sealing between the cover plate 4 and the mixing barrel 1. The cooperation between the sealing gasket 403 and the cover plate 4 can further reduce dust pollution during the mixing process, thereby protecting the operating environment and personnel health.

[0032] The fixed plate 3 is provided with a suction pump 5 connected with the mixing barrel 1, and the extraction end of the suction pump 5 is connected with a suction pipe 6. The design of the suction pump 5 and the suction pipe 6 allows the suction pipe 6 to be directly inserted into the material bag. This design effectively blocks the direct flying path of dust when the material is dumped. The suction pipe 6 is a corrugated pipe, and the suction pipe 6 can be extended in length. The outside of the mixing barrel 1 is provided with a sleeve 103 for limiting the suction pipe 6. The discharge end of the suction pump 5 is connected with a feed pipe 501 located on the inside of the mixing barrel 1. A water pump 7 is installed on the fixed plate 3. The water pump 7 transports water to the nozzle 9 in the mixing barrel 1 through the water supply pipe 8, which is used to wet the material and reduce dust flying. By accurately controlling the amount of water sprayed and the timing of water spraying, the generation of dust during the mixing process is effectively suppressed, and the mixing effect is improved. The drainage end of 7 is connected to a water supply pipe 8, which is provided with a water inlet pipe 801. The water inlet pipe 801 passes through the fixed plate 3 and extends to the inner side of the mixing barrel 1. The water supply pipe 8 is provided with an electric control valve 802. The electric control valve 802 can be used to control the on and off of the water supply pipe 8. When the material conveying is completed, the nozzle 9 can be closed by the electric control valve 802. The other end of the water supply pipe 8 is provided with a nozzle 9. A protective cover 10 for shielding the suction pump 5 and the water pump 7 is installed on the fixed plate 3. The protective cover 10 is cylindrical and has a heat dissipation hole 1001 on the end of the protective cover 10 away from the fixed plate 3. The protective cover 10 can shield and protect auxiliary equipment such as the suction pump 5 and the water pump 7, thereby extending the service life of the auxiliary equipment and reducing the impact of noise and vibration on the surrounding environment. The design of the heat dissipation hole 1001 ensures ventilation and heat dissipation inside the protective cover 10, preventing the equipment from overheating.

[0033] The working principle of the above embodiment is:

[0034] When making plastic, open the opening of the plastic material bag and insert the suction pipe 6 on the suction pump 5 into the plastic material bag. Start the suction pump 5 through the control device. After starting the suction pump 5, the suction pump 5 quickly generates a strong negative pressure in the suction pipe 6. This negative pressure effect sucks the air and the accompanying dust particles in the material bag through the suction pipe 6, and then discharges them into the mixing barrel 1 through the feed pipe 501. When discharging the plastic, start the water pump 7, and the water pump 7 performs a pumping operation through the water pumping pipe 701, and then transports it through the water supply pipe 8, and flows into the mixing barrel 1 through the water inlet. At the same time, the water mist sprayed by the nozzle 9 evenly covers the surface of the material, further moistening the material and reducing the possibility of dust flying. This wetting effect not only helps to reduce the generation of dust during the mixing process, but also promotes the uniformity of the material. To mix the materials evenly and improve the stirring effect, the motor drives the stirring rod to rotate, and the stirring blades on the stirring rod continuously cut and turn the materials to make them fully mixed. At the same time, due to the closed or semi-closed design of the stirring barrel 1, and the sealing effect of the cover plate 4 and the sealing gasket 403, the dust generated during the stirring process is confined to the inside of the stirring barrel 1, reducing the overflow of dust and the pollution to the operating environment. When the material mixing is completed, the discharge pipe 101 is opened by controlling the hand valve 102, and the stirred material can be smoothly discharged from the stirring barrel 1. At this time, the suction pump 5 and the water pump 7 can be turned off as needed to reduce energy consumption and noise. At the same time, due to the shielding protection of the protective cover 10 on auxiliary equipment such as the suction pump 5 and the water pump 7, the service life of these equipment is extended, and the impact of the noise and vibration generated by its operation on the surrounding environment is also effectively reduced.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
