Description

Technical Field

[0001] The utility model relates to the technical field of material mixing, in particular to a material mixing and batching device. Background Art

[0002] In the process of repairing converters, spray repair equipment is often needed. The mixing and batching device is an important device in the spray repair equipment. If the materials mixed by the mixing and batching device are not uniform enough, it will easily cause blockage in the next spraying process.

[0003] Existing equipment mostly adopts mechanical stirring to stir and mix. The powder material and water used for repair are added into a mixing tank and stirred by mechanical blades. During the stirring process, the repair powder material is easy to stick to the middle part of the mechanical blade. The middle part of the mechanical blade moves slowly and is subjected to small friction. This part of the repair powder is easy to clump and adhere to the blade. In the subsequent spray repair process, this part of the agglomerated repair powder material may fall off and fall into the mixed repair material. When this part of the agglomerated repair material is transported to the nozzle, it is easy to cause nozzle blockage, resulting in machine failure.

[0004] In summary, there is an urgent need for a mixing and batching device to solve or at least partially solve the problems existing in the prior art. Utility Model Content

[0005] The utility model aims to provide a mixing and batching device, aiming to solve the problem that the repair powder material in the existing design is easy to adhere to the mixing blades and cause uneven mixing. The specific technical solution is as follows:

DETAILED DESCRIPTION

[0025] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below, and preferred embodiments of the present invention are given. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0027] Example:

[0028] See also Figure 1-Figure 4 The present embodiment provides a mixing and batching device, including a frame 1, a mixing tank 2, a stirring air pipe 3 and a discharge valve 4. The mixing tank 2 is arranged on the frame 1, the stirring air pipe 3 is arranged at the lower part of the mixing tank 2 and is connected with the mixing tank, the discharge valve 4 is arranged at the bottom of the mixing tank 2, and the mixing tank 2 is also provided with a material inlet 21.

[0029] Specifically, the frame 1 is a square frame 1, and the frame 1 is supported on the ground by four legs. Of course, in other embodiments, the frame 1 may not be limited to this form, and may also be other structures, mainly used to support the mixing tank 2. The mixing tank 2 is installed on the frame 1, and the outlet at the bottom of the mixing tank 2 is arranged at a certain height from the ground, generally between 20 cm and 30 cm, so as to facilitate the installation of other material receiving equipment at the outlet at the bottom of the mixing tank 2, such as installing a conveying pipeline at the outlet.

[0030] It can be understood that when mixing is required, the repair powder material and water are poured into the mixing tank 2, and the water is allowed to naturally penetrate into the repair powder material. In this way, the repair powder material is not easy to generate dust during the later mixing process. After the water completely penetrates into the repair powder material, high-pressure gas is introduced into the mixing tank 2 from the lower part of the mixing tank 2. The high-pressure gas is generally air. Of course, in other embodiments, the high-pressure gas can also be other gases that will not chemically react with the repair material. The high-pressure gas moves from the bottom of the mixing tank 2 toward the upper part of the mixing tank 2, and is finally discharged into the air from the feed port 21. In the process of the high-pressure gas moving upward, the repair powder material and water at the bottom of the mixing tank 2 are pushed to move upward from the middle of the bottom of the tank body. The mixture of the repair powder material and water moves to the top of the material pile where the repair powder material and water are accumulated, and then flows to the inner wall of the mixing tank 2 around under the action of gravity. After the repair powder material and water in the middle of the bottom flow upward, the surrounding repair powder material and water flow to the middle of the bottom to supplement the position occupied by the original repair powder material and water in the middle. The material at the top of the material pile close to the inner wall of the mixing tank 2 moves downward to supplement the position occupied by the repair powder material and water at the bottom close to the inner wall of the mixing tank 2, thereby forming a circulating flow to achieve the effect of mixing and stirring. There is no mechanical stirring in the whole process, and no adhesion will be generated, so that the stirring and mixing are more uniform.

[0031] Furthermore, the lower part of the mixing tank 2 is arranged in a conical shape with a larger top and a smaller bottom, and the discharge valve 4 is arranged at the bottom of the cone. The conical bottom with a larger top and a smaller bottom has a good guiding effect, so that the material in the mixing tank 2 can be smoothly discharged from the discharge valve 4 at the bottom of the cone. The stirring air pipe 3 is arranged on the side wall surface of the cone and is set close to the discharge valve 4, so that the stirring air pipe 3 is set as close to the bottom as possible, so that the repair powder material and water at the bottom can move upward under the drive of the high-pressure gas.

[0032] Furthermore, the stirring air pipe 3 is eccentrically arranged relative to the axis of the mixing tank 2. When the high-pressure gas is sprayed into the mixing tank 2 along the eccentric position, it will not only drive the bottom repair powder and water to move toward the upper part of the mixing tank 2, but also drive the repair powder and water to rotate along the axis of the mixing tank 2. The combination of these two movements enables the repair powder material and water in the mixing tank 2 to be mixed more quickly and evenly, making the mixing more sufficient and the obtained mixed material more delicate.

[0033] Furthermore, an air pipe valve 31 is installed on the stirring air pipe 3, specifically the air pipe valve 31 is a ball valve. In other embodiments, the main air pipe valve 31 can also be a butterfly valve or other valves that can control the gas flow and flow rate. The stirring speed can be controlled by controlling the flow rate and flow of the gas flowing from the stirring air pipe 3 to the mixing tank 2. A smaller flow rate and flow rate are required in the initial stage of stirring to allow the repair powder material to combine with water to prevent excessive airflow from directly blowing away the repair powder material that has not been combined with water, thereby causing waste of materials. After the repair material and water are combined, the flow rate and flow rate are increased to allow the repair material and water to be mixed more evenly.

[0034] Furthermore, the feed port 21 is located at the top of the mixing tank 2, and a feed hopper 22 is provided at the feed port 21, and the feed hopper 22 is docked with the feed port 21, and a bag opening cone 23 for cutting the bag is provided in the feed hopper 22. Specifically, the bag opening cone 23 in the feed hopper 22 faces upward, and the lower part of the feed hopper 22 is in a cone shape with a large top and a small bottom, so as to facilitate the guidance of the material in the feed hopper 22 so that it can smoothly enter the mixing tank 2 from the feed port 21. It can be understood that the repair powder material is usually packaged in nylon bags, and the weight of a bag often weighs tens of kilograms, and the height of the feed hopper 22 is relatively high, which requires manual handling and has certain difficulties. In reality, a crane is generally used for lifting, but the nylon bag needs to be opened after lifting, and a cutter is used to cut it from the bottom of the nylon bag manually, so that the repair powder material in the nylon bag flows out. It is more convenient to open the nylon bag using the bag opening cone 23. It is only necessary to use a crane to lift the nylon bag above the bag opening cone 23 and lower it. The nylon bag is punctured by the bag opening cone 23 under the action of its own weight, so that the repair powder material in the nylon bag flows out. There is no need to manually cut the nylon bag, which reduces labor intensity.

[0035] Further, the bag opening cone 23 comprises a plurality of cutting plates 231, which are staggered to form an upwardly contracting cone. In this embodiment, four cutting plates 231 are used, and the four cutting plates 231 are evenly arranged along the circumference of the feed hopper 22. In other embodiments, the cutting plates 231 can also be three, five or more. The four cutting plates 231 meet in the middle of the feed hopper 22 to form an upward spike to facilitate piercing the nylon bag containing the repair powder material. The upper part of the cutting plate 231 has a cutting blade 2311, and the cutting blade 2311 forms an angle β2312 with the vertical axis, and the angle β2312 is between 10 degrees and 45 degrees. In this embodiment, the angle β2312 is 30 degrees. The cutting blade 2311 cuts the nylon bag, so that the nylon bag is cut into a larger gap, so that the repair powder material in the nylon bag can quickly flow out from the gap into the feed hopper 22.

[0036] Furthermore, a liquid inlet pipe 25 is provided at the top of the mixing tank 2, and a liquid pipe valve 251 for controlling the liquid flow rate is installed on the liquid inlet pipe 25. The liquid inlet pipe 25 is used to transport water mixed with the repair powder material, and of course, it can also transport other liquid materials for mixing. In addition, an on-off valve 24 for controlling the material entering the mixing tank 2 is provided between the hopper 22 and the mixing tank 2. It can be understood that the on-off valve 24 is closed first, the repair powder material is loaded into the hopper 22, and the on-off valve 24 and the liquid pipe valve 251 are opened at the same time, so that the repair powder material and water fall from the top of the mixing tank 2 to the bottom of the mixing tank 2 at the same time. In the process of the repair powder material and water falling from the top of the mixing tank 2 to the bottom, the repair powder material and water are preliminarily mixed, and the relative opening of the on-off valve 24 and the liquid pipe valve 251 is adjusted to control the mixing ratio of the repair powder material and water.

[0037] Furthermore, a workbench 11 is provided on the frame 1, and the workbench 11 is located on the upper part of the mixing tank 2. A ladder 12 is also provided on the frame 1, and the ladder 12 is provided corresponding to the workbench 11. Workers can climb up to the workbench 11 through the ladder 12 to work. A guardrail 111 is provided on the workbench 11, and the guardrail 111 is provided on the outer periphery of the workbench 11. The guardrail 111 protects the workers on the workbench 11, prevents the workers from falling from the workbench 11, and maintains the construction safety of the workers.

[0038] The working principle of the present embodiment is as follows: first, all valves are closed, and the repair powder material in the nylon bag is hoisted above the feed hopper 22 and slowly lowered to allow the bag opening cone 23 to cut the nylon bag, so that the repair powder material in the nylon bag flows downward and enters the feed hopper 22. At the same time, the opening and closing valve 24 and the liquid pipe valve 251 are opened, and the relative openings of the opening and closing valve 24 and the liquid pipe valve 251 are controlled, so that the repair powder material and water fall from the top of the mixing tank 2 to the bottom of the mixing tank 2 in a set proportion for preliminary mixing. Let it stand for a period of time to allow the water to fully penetrate into the repair powder material, open the air pipe valve 31, and allow high-pressure gas to enter the mixing tank 2 from the stirring air pipe 3, and the repair powder material in the mixing tank 2 Under the driving force of high-pressure gas, the repair powder material and water in the middle of the bottom of the tank body move upward along the axis of the tank body and reach the top of the material pile formed by the repair powder material and water. Because the repair powder material and water accumulated in the middle of the material pile are increasing, when a certain height is reached, they will slide around under the action of gravity. After the repair powder material and water in the middle of the bottom of the tank body are extracted, the repair powder and water around the bottom will flow to the middle, and the repair powder and water around the bottom need the repair powder and water around the top to flow downward to compensate, and finally form a flow from the middle of the bottom to the middle of the top, then to the top, then to the bottom, and then to the middle of the bottom, forming a circular flow, thereby forming a flow mixture. The stirring air pipe 3 is eccentrically set, and the high-pressure gas provides a thrust along the circumferential direction of the mixing tank 2 to the repair powder material and water in the mixing tank 2, so that the repair powder material and water in the mixing tank 2 rotate and mix along the axial direction of the mixing tank 2, so that the repair powder material and water in the mixing tank 2 can be fully mixed. After the mixing is completed, the discharge valve 4 is opened to discharge the mixture.

For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
