Description
Technical Field
[0001] This utility model relates to the field of refractory material processing technology, specifically to a high-efficiency refractory material mixing device. Background Technology
[0002] Refractory materials are indispensable basic materials in high-temperature industries such as steel, building materials, and non-ferrous metals. The uniformity and stability of their quality directly affect the lifespan and operational safety of high-temperature kilns. The mixing process is a key step in refractory material production. Its core objective is to fully and uniformly mix raw materials of different particle sizes and compositions (such as aggregates, powders, and binders). The uniformity of the mixture largely determines the performance of the final refractory products.
[0003] Refractory raw materials (such as moist clay, fine powder, etc.) have poor flowability, and are prone to sloshing, sticking to the walls, or even clogging during the feeding process. This not only leads to production interruptions, requiring manual cleaning and affecting production efficiency, but more seriously, blockages prevent raw materials from continuously and stably entering the mixing silo according to the preset ratio, resulting in batch-to-batch imbalances and severely affecting the uniformity of mixing and the consistency of product quality.
[0004] Therefore, there is a need for a high-efficiency mixing device that can provide a variety of targeted feeding schemes for refractory raw materials with different properties, and can effectively prevent blockage and ensure continuous and stable feeding. Utility Model Content
[0005] The purpose of this invention is to provide a high-efficiency mixing device for refractory materials to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a base, a mixing hopper, and a feeding hopper. A drive motor is fixedly mounted on the top of the base, and a support frame is fixedly mounted on one side of the drive motor. The mixing hopper is fixedly mounted on the top of the support frame, and a feeding hopper is located on the top of the mixing hopper. The feeding hopper contains three different feeding mechanisms: a horizontal conveying component, an anti-blocking conveying component, and a natural discharge component. The horizontal conveying component includes a rotating shaft and a conveyor belt. Two rotating shafts are arranged parallel to each other inside the feeding hopper, and a conveyor belt is sleeved around the two rotating shafts. The end point of the conveyor belt is located above the feeding channel, and the bottom of the feeding channel is connected to the top of the mixing hopper. The anti-blocking conveying assembly includes a sprocket shaft, a chain conveyor belt, a transfer bin, a second drive shaft, and an anti-blocking stirring plate. Three sprocket shafts that gradually slope downwards are provided above the conveyor belt. The chain conveyor belt is fitted onto the surface of the three sprocket shafts. The second drive shaft is provided through the feed bin at the end of the chain conveyor belt. An anti-blocking stirring plate is fixedly installed on the surface of the second drive shaft. This assembly is used to convey refractory material raw materials into the feed channel to prevent blockage. The natural feeding assembly includes a feeding hopper, a pin, and a baffle. A conical feeding hopper is provided through the top of the feeding bin, and a pin is provided through the bottom of the feeding hopper. A baffle is provided outside the pin, and the baffle blocks the connection between the feeding hopper and the feeding bin. The baffle can be rotated open by pressing down the refractory material, so that the refractory material can be transported into the feeding channel.
[0007] Preferably, the output end of the drive motor is connected to a transmission wheel, the transmission wheel is fitted with a first belt, the other end of the first belt is fitted onto a first driven wheel, the first driven wheel is fixedly connected to a first transmission shaft, and the first transmission shaft is disposed through the mixing hopper.
[0008] Preferably, a spiral rod is fixedly arranged in a ring on the surface of the first drive shaft, and multiple T-shaped stirring rods are uniformly fixedly arranged on the surface of the first drive shaft between the spiral rods.
[0009] Preferably, the second drive shaft passes through the surface of the feed hopper and is fixedly connected to a second driven wheel. A second belt is sleeved on the outside of the second driven wheel, and the other end of the second belt is also sleeved on the surface of the drive wheel.
[0010] Preferably, the feed bin is fixedly provided with side plates on both sides of the conveyor belt.
[0011] Preferably, the feeding channel is provided with a partition plate to separate the raw materials of the horizontal conveying component and the anti-blocking conveying component.
[0012] Preferably, the mixing hopper has a discharge port at the bottom, and the discharge port is equipped with a discharge baffle. The discharge baffle can be pulled to control the opening and closing of the discharge port.
[0013] The technical effects and advantages of this utility model are as follows: This invention employs three feeding mechanisms: a horizontal conveying component, an anti-blocking conveying component, and a natural feeding component. These mechanisms allow for flexible selection of the most suitable feeding method based on the flowability, particle size, and moisture content of the refractory raw materials. For example, for aggregates with good flowability, the natural feeding component enables rapid and continuous feeding. For fine powders that are prone to adhesion or agglomeration, the chain conveyor belt of the anti-blocking conveying component, in conjunction with the anti-blocking mixing plate, forces the conveyor to break up the raw materials, effectively preventing material sloshing. For intermediate-characteristic raw materials requiring stable conveying, the horizontal conveying component ensures uniform feeding. Attached Figure Description

The base 1 is a rectangular steel plate structure with anti-slip pads at the bottom to enhance stability. A drive motor 2 is fixedly installed on one side of the top of the base 1, and its output end is connected to a transmission wheel 7. A support frame 3 is welded to the base 1 and located on one side of the drive motor 2. The mixing bin 4 is fixed to the top by bolts. The mixing bin 4 is a cylindrical structure with a smooth inner wall and a tapered bottom. It has a discharge port 16, and a discharge baffle 17 is inserted into the discharge port 16. The feeding bin 5 is welded to the top of the mixing bin 4 and has a rectangular box structure. It has three feeding mechanisms inside: a horizontal conveying component 61, an anti-blocking conveying component 62, and a natural discharge component 63. The bottom of the feeding bin 5 has a feeding channel 51 that runs through and connects to the top of the mixing bin 4. The feeding channel 51 is equipped with a partition plate 15, which divides the channel into two independent parts, corresponding to the discharge areas of the horizontal conveying component 61 and the anti-blocking conveying component 62, respectively, to prevent different raw materials from mixing during the feeding process.
[0021] Horizontal conveying assembly 61: Located at the lower part of the feed hopper 5, it includes two parallel rotating shafts 611 and a conveyor belt 612 sleeved on the outside. The rotating shafts 611 are fixed to the side wall of the feed hopper 5 by bearing seats. One of the rotating shafts 611 is connected to an external motor (not shown) by a coupling or driven by belt drive. The conveyor belt 612 is a rubber belt with anti-slip texture on the surface, used to smoothly convey granular or medium-flow raw materials. The feed hopper 5 has side plates 613 fixed on both sides of the conveyor belt 612 to prevent raw materials from overflowing. The end of the conveyor belt 612 is located above the feed channel 51. After the raw materials are conveyed to the feed channel 51 by the conveyor belt 612, they fall into the mixing hopper 4.
[0022] Anti-clogging conveying assembly 62: Located above the horizontal conveying assembly 61, it includes three sprocket shafts 621, a chain conveyor belt 622, a second drive shaft 623, and an anti-clogging stirring plate 624. The three sprocket shafts 621 are arranged at an angle. The sprocket shafts 621 drive the chain conveyor belt 622 through sprockets. The chain conveyor belt 622 is a metal chain structure, suitable for conveying fine powders that are easy to adhere or clump. The end of the chain conveyor belt 622 is connected to the feed channel 51. The second drive shaft 623 passes through the side wall of the feed hopper 5 and is supported by bearings. An anti-clogging stirring plate 624 is fixed on its surface. The anti-clogging stirring plate 624 is paddle-shaped and located at the end of the chain conveyor belt 622 to break up clumped raw materials. The outer end of the second drive shaft 623 is fixed with a second driven wheel 13, which is connected to the drive wheel 7 of the drive motor 2 through a second belt 14 to realize power transmission.
[0023] Natural feeding component 63: Located at the top of the feeding hopper 5, it includes a conical feeding hopper 631, a pin 632, and a baffle 633. The feeding hopper 631 is welded to the top surface of the feeding hopper 5, and its bottom opening is connected to the inside of the feeding hopper 5. The pin 632 is horizontally installed at the opening. The baffle 633 is hinged to the pin 632 and can rotate around the pin 632. In its natural state, the baffle 633 is closed by gravity, blocking the bottom opening of the feeding hopper 631. When free-flowing aggregate is added from the feeding hopper 631, the raw material presses down on the baffle 633, causing it to rotate and open, and the raw material falls naturally into the feeding channel 51.
[0024] The mixing chamber 4 is equipped with a first drive shaft 10. The first drive shaft 10 passes through both ends of the mixing chamber 4 via bearings. The first driven wheel 9 is fixed at the outer end of the first drive shaft 10 and is connected to the drive wheel 7 of the drive motor (2) via the first belt 8. A spiral rod 11 is fixed in a ring on the surface of the first drive shaft 10 for axially pushing the raw material. Multiple T-shaped stirring rods 12 are uniformly welded between the spiral rods 11 on the surface of the first drive shaft 10 for radial shearing and efficient mixing of the raw material.
[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
