Description

Technical Field

[0001] This utility model belongs to the field of powder mixing technology, and more specifically, it relates to a powder mixing device that can add powder in a quantitative manner. Background Technology

[0002] Refractory materials refer to a class of inorganic non-metallic materials with a refractoriness of not less than 1580 degrees Celsius, characterized by maintaining stable physical and chemical properties under high-temperature environments. Refractory materials are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate industry, power industry, and other industrial fields. They play an indispensable role as structural and lining materials in high-temperature process equipment, and are crucial to the development of high-temperature industries. Refractory powder is one of the key components of refractory materials; by selecting appropriate refractory powder, the performance of refractory materials can be adjusted to meet the needs of different working environments.

[0003] In the existing technology, the manufacturing process of refractory materials usually requires mixing a variety of different powders in a precise ratio. However, the traditional method of adding powder is mostly based on the operator's experience to add powder into the mixing device. This leads to a large error in the amount of powder added and inaccurate powder ratio, which affects the performance and quality of refractory materials.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] To solve the above-mentioned technical problems, the present invention provides a powder mixing device that can quantitatively add powder, including a mixing tank, a conveying pipe installed at the upper end of the mixing tank, the conveying pipe communicating with the interior of the mixing tank, a storage tank installed at the upper end of the conveying pipe, a storage bin having multiple storage compartments inside the storage bin, a multiple slot having multiple slots at the upper end of the conveying pipe, the storage compartments corresponding one-to-one with the slots and communicating with the conveying pipe, an opening and closing component installed at the top of the conveying pipe, the opening and closing component being used to change the opening and closing state of the slots, and a mixing component installed inside the mixing tank.

[0006] The opening and closing assembly includes a power assembly, which is installed at the top of the conveying pipe. Multiple connecting plates are installed at the lower end of the drive shaft of the power assembly. The number of connecting plates is the same as the number of slots. A baffle is installed at one end of the connecting plate. One side of each baffle is in contact with the inner wall of the conveying pipe. The baffles correspond one-to-one with the slots, and the baffles can completely close the slots.

[0007] A positioning ring is installed on the upper end of the inner wall of the conveying pipeline. Multiple positioning grooves are opened on the positioning ring. The number of positioning grooves is the same as the number of baffles. Each baffle is slidably installed in one positioning groove.

[0008] Multiple guide plates are installed in a staggered manner along the height direction on the inner wall of the conveying pipeline, and the multiple guide plates are inclined downward towards the center end of the conveying pipeline.

[0009] Each side of the storage compartment has an observation window, and the observation window is engraved with scale.

[0010] A discharge plate is installed on one side of the mixing tank, which is used to seal the discharge port of the mixing tank.

[0011] The outer surface of the mixing tank is fitted with multiple fixing rings, and multiple fixing brackets are installed at the lower end of each fixing ring. The fixing brackets are all mounted on a fixing base.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model involves pouring two powders into different storage bins according to the required ratio. Once the correct ratio of the powders has been determined, the powders are simultaneously poured into a conveying pipe through a trough. The powders are then poured into a mixing tank through the conveying pipe. This device ensures that the powders are fully mixed according to the required quantitative ratio, ensuring accurate powder proportions and guaranteeing the performance and quality of the refractory materials.

[0014] 2. This utility model installs a guide plate inside the conveying pipeline, so that when the powder in the storage bin falls into the conveying pipeline at the same time, it will collide under the action of the guide plate. The collision changes the flow path of the powder, so that the powder particles have more opportunities to collide, disperse and recombine with each other, thereby achieving mixing first and then falling into the mixing tank. This eliminates the need for excessive stirring operations of the mixing components inside the mixing tank, saving energy consumption, while also ensuring that the powder is fully mixed and improving the quality of the finished product.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1 Section 5 provides a clear and complete description of the technical solutions of the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0023] Please see Figures 1-3 As shown:

[0024] This embodiment provides a quantitative powder mixing device, including a mixing tank 1, a conveying pipe 2 installed at the upper end of the mixing tank 1, the conveying pipe 2 communicating with the interior of the mixing tank 1, a storage tank 3 installed at the upper end of the conveying pipe 2, and multiple storage compartments 4 provided inside the storage tank 3, including but not limited to two, with equal internal volumes of the storage compartments 4, multiple slots 5 opened at the upper end of the conveying pipe 2, the storage compartments 4 corresponding one-to-one with the slots 5 and communicating with the conveying pipe 2, an opening and closing component 6 installed at the top of the conveying pipe 2, the opening and closing component 6 being used to change the opening and closing state of the first slot 5 and the second slot 5, and the opening and closing component 6 initially being in the closed state of the first slot 5 and the second slot 5, and a mixing component 7 installed inside the mixing tank, the mixing component 7 being used to stir the powder in the cavity of the mixing tank 1.

[0025] In practical use, various powders are poured into the storage bin 4 according to the required ratio. Once the correct ratio of the poured powders is confirmed, the opening and closing component 6 is driven to rotate, so that it no longer blocks the slot 5. This allows the powders in the storage bin 4 to fall into the conveying pipe 2 at the same time. The powders are then transported to the mixing tank 1 through the conveying pipe 2. The mixing component 7 then stirs the powders to ensure they are fully mixed. This device can achieve the goal of fully mixing the powders according to the required quantitative ratio, ensuring the performance and quality of the refractory materials.

[0026] like Figure 1 , Figure 3 , Figure 5As shown, the opening and closing assembly 6 includes a power assembly 8, which is installed at the top of the conveying pipe 2. The lower end of the drive shaft of the power assembly 8 is equipped with multiple connecting plates 9. The number of connecting plates 9 is the same as the number of slots 5. A baffle 10 is installed at one end of the connecting plate 9. One side of the baffle 10 is in contact with the inner wall of the conveying pipe 2. The baffle 10 corresponds to the slots 5 one by one, and the baffle 10 can completely close the slots 5 so that the storage bin 4 is no longer connected to the conveying pipe 2. Therefore, when it is necessary to pour the correctly proportioned material in the storage bin 4 into the mixing tank 1, the power assembly 8 drives the connecting plate 9 to rotate, so that the connecting plate 9 drives the baffle 10 to move to a new position and no longer closes the slots 5. This allows the powder in the storage bin 4 to be conveyed to the conveying pipe 2 at the same time.

[0027] The power unit 8 is an existing device, including but not limited to a motor.

[0028] like Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, a positioning ring 11 is installed on the upper end of the inner wall of the conveying pipe 2. The positioning ring 11 has multiple positioning grooves 12. The number of positioning grooves 12 is the same as the number of baffles 10. Each baffle 10 is slidably installed in a positioning groove 12. The connecting plate 9 can drive the baffles 10 to slide in the same direction in the positioning groove 12 at the same time, so that they will not close the groove 5. The powder in the storage bin 4 can enter the conveying pipe 2 at the same time. The positioning groove 12 can ensure the stability of the baffles 10 during the movement.

[0029] like Figure 1 , Figure 3 As shown, multiple guide plates 13 are installed in a staggered manner along the height direction on the inner wall of the conveying pipe 2, and the multiple guide plates 13 are inclined downward towards the center of the conveying pipe 2. This allows the powder from the storage bin 4 to collide with each other under the action of the guide plates 13 when it falls into the conveying pipe 2. The collision changes the flow path of the powder, giving the powder particles more opportunities to collide, disperse and recombine. This allows them to be mixed first and then fall into the mixing tank 1, so that they no longer need to be stirred by the mixing component 7 inside the mixing tank 1. At the same time, it can also ensure that the powder is fully mixed and improve the quality of the finished product.

[0030] like Figure 2 As shown, each side surface of the storage chamber 4 is provided with an observation window 14, and a scale is engraved on one side of the observation window 14. Thus, the amount of powder poured into the storage chamber 4 can be accurately known through the observation window 14 and the scale, so that the ratio is correct and the quality of the finished product is improved.

[0031] like Figure 1-2As shown, a discharge plate 15 is installed on one side of the mixing tank 1. The discharge plate 15 is used to seal the discharge port of the mixing tank 1 so that after the powder mixing operation inside the mixing tank 1 is completed, the discharge plate 15 can be pulled to remove the seal from the discharge port of the mixing tank 1. The operator can then remove the powder from the mixing tank 1 through the discharge port. The discharge plate 15 can seal the discharge port of the mixing tank 1 when the powder is being mixed inside the mixing tank 1 to prevent the powder from leaking out of the discharge port of the mixing tank 1.

[0032] like Figure 2 As shown, multiple fixing rings 16 are fitted on the outer surface of the mixing tank 1, and multiple fixing brackets 17 are installed at the lower end of each fixing ring 16. The fixing brackets 17 are all installed on the fixing base 18, so that the overall stability of the mixing tank 1 can be guaranteed by the fixing base 18, and its safety can be guaranteed when mixing.

[0033] The working principle of the quantitative powder mixing device provided by this utility model is as follows: By pouring two or more powders into the storage bin 4 according to the required ratio, once the correct ratio of the added powders is confirmed, the drive power component 8 drives the baffle 10 to rotate in the same direction in the positioning groove 12 through the connecting plate 9, so that the baffle 10 no longer blocks the groove 5, and the powder in the storage bin 4 can be transported to the conveying pipe 2 at the same time. When the powder enters the conveying pipe 2, it will collide under the action of the guide plate 13. Under the collision, the flow path of the powder itself is changed, so that the powder particles have more opportunities to collide, disperse and recombine with each other, achieving pre-mixing. Then, it falls into the mixing tank 1 and is fully mixed by the mixing component 7, thereby completing the powder mixing operation. This ensures accurate powder metering, guarantees the performance and quality of refractory materials, and also reduces the mixing time of the mixing component 7, saving energy.

[0034] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
