Description

Technical Field

[0001] This utility model relates to the field of refractory material screening technology, and more specifically, to a screening and homogenization device for borax-modified refractory material micro powder additives. Background Technology

[0002] Borax-modified refractory powder additives refer to powdered additives made by ultra-fine grinding of borax as the core modifying component. They are mainly used to optimize the performance of refractory materials (such as corundum, mullite, magnesia, etc.). Borax decomposes at high temperatures to form a low-melting-point glass phase, which can promote the bonding between refractory particles, reduce the sintering temperature, and reduce energy consumption during firing. The glass phase can fill the pores inside the refractory material, improve the material density and mechanical strength. Sieving and homogenization are key steps to ensure the stability of the additive's performance and thus ensure the quality of the refractory material.

[0003] When screening existing refractory materials, excessively large particles cannot fill the gaps in the refractory material. Therefore, particles that exceed the size limit are separated by a screen to ensure that the particle size of the additive meets the design requirements. However, it is inconvenient to adjust the diameter of the screen holes. If additives with different particle size standards are required, the entire set of screens often needs to be replaced manually after stopping the machine, which is time-consuming and labor-intensive. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a sieving and homogenizing device for borax-modified refractory powder additives, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sieving and homogenizing device for borax-modified refractory micro powder additives, comprising a feed box, a riser, and a storage box. The bottom end of the riser is fixedly connected to the feed box and is located at the bottom of the storage box. A transparent plate is fixedly connected to the bottom end of the storage box, and the bottom end of the transparent plate is fixedly connected to the riser. A first screen is fixedly embedded in the bottom of the storage box. An adjustment component is provided at the bottom of the first screen. The adjustment component includes a mounting frame, a second self-locking motor, a second rotating shaft, and a second screen. The mounting frame is fixedly installed at the top of the feed box. The second self-locking motor is fixedly installed at the bottom of the mounting frame, and the output shaft end of the second self-locking motor is fixedly connected to the second rotating shaft. The top end of the second rotating shaft is fixedly connected to the second screen, and the top end of the second screen is in contact with the first screen.

[0006] Furthermore, a scale is provided at the bottom of the transparent plate, and the scale is fixedly sleeved on the outside of the riser.

[0007] As can be seen, in the above technical solution, the position of the second screen can be observed by using a transparent plate and a ruler.

[0008] Furthermore, a stepper motor is fixedly connected to the top of the storage box, and a first rotating shaft is fixedly connected to the output shaft end of the stepper motor. Multiple stirring rods are fixedly sleeved on the outside of the first rotating shaft, and the multiple stirring rods are all located inside the storage box.

[0009] As can be seen, in the above technical solution, the additives in the storage tank are stirred by multiple stirring rods, which can break up the micro powder agglomerates.

[0010] Furthermore, a feed hopper is fixedly connected to the top of the storage box, and a discharge hopper is fixedly connected to one side of the guide box.

[0011] It can be seen that the above technical solutions are designed to facilitate material feeding and discharging.

[0012] Furthermore, a vibration assembly is provided at the bottom of the guide box. The vibration assembly includes a base plate, multiple telescopic rods, two upright plates, a first self-locking motor, an eccentric wheel, and multiple springs. The top and bottom ends of the multiple telescopic rods are fixedly connected to the guide box and the base plate, respectively.

[0013] Furthermore, the bottom ends of both upright plates are fixedly connected to the base plate, the first self-locking motor is fixedly installed on the front side of one of the upright plates, and the output shaft end of the first self-locking motor is fixedly connected to the eccentric wheel. The front and rear ends of the eccentric wheel are movably connected to the two upright plates through bearings.

[0014] Furthermore, the multiple springs are located on the outside of the multiple telescopic rods, and the top and bottom ends of the multiple springs are fixedly connected to the guide box and the base plate, respectively.

[0015] It can be seen that the above technical solution facilitates the resetting of the feed box.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. This utility model uses a second self-locking motor to drive a second rotating shaft to rotate, which in turn drives a second screen to rotate. The distance between the screen holes on the first and second screens can be adjusted as needed to screen additives of different particle sizes. A stepper motor drives multiple stirring rods to rotate, which stirs the additives in the storage box, breaking up micro-powder agglomerates. The operation is simple and convenient for screening and homogenizing additives of different particle sizes, saving time and effort.

[0018] 2. This utility model uses a first self-locking motor to drive an eccentric wheel to rotate. When the top of the eccentric wheel contacts the guide box, the eccentric wheel continues to rotate, which will drive the guide box to move upward. At the same time, the guide box will drive four springs to stretch. When the eccentric wheel moves away from the guide box, the four springs will rebound and drive the guide box to reset. This cycle repeats, vibrating the additives in the guide box and storage box, accelerating the falling speed of the additives. The structure is simple and easy to use. Attached Figure Description

The assembly includes a mounting frame 1101, a second self-locking motor 1102, a second rotating shaft 1103, and a second screen 1104.

The top of the second rotating shaft 1103 is fixedly connected to the second screen 1104, and the top of the second screen 1104 is in contact with the first screen 10.

[0028] Furthermore, a scale 9 is provided at the bottom of the transparent plate 8, and the scale 9 is fixedly sleeved on the outside of the riser 2. A stepper motor 5 is fixedly connected to the top of the storage box 3. A first rotating shaft 12 is fixedly connected to the end of the output shaft of the stepper motor 5. Multiple stirring rods 13 are fixedly sleeved on the outside of the first rotating shaft 12, and the multiple stirring rods 13 are all located inside the storage box 3. A feed hopper 4 is fixedly connected to the top of the storage box 3, and a discharge hopper 6 is fixedly connected to one side of the guide box 1.

[0029] Furthermore, a vibration assembly 7 is provided at the bottom of the guide box 1. The vibration assembly 7 includes a base plate 701, multiple telescopic rods 702, two upright plates 703, a first self-locking motor 704, an eccentric wheel 705, and multiple springs 706. The top and bottom ends of the multiple telescopic rods 702 are fixedly connected to the guide box 1 and the base plate 701, respectively. The bottom ends of the two upright plates 703 are fixedly connected to the base plate 701. The first self-locking motor 704 is fixedly installed on the front side of one of the upright plates 703, and the output shaft end of the first self-locking motor 704 is fixedly connected to the eccentric wheel 705. The front and rear ends of the eccentric wheel 705 are movably connected to the two upright plates 703 through bearings. The multiple springs 706 are located on the outside of the multiple telescopic rods 702, and the top and bottom ends of the multiple springs 706 are fixedly connected to the guide box 1 and the base plate 701, respectively.

[0030] The base plate 701 is fixed with bolts, and the base plate 701 supports the guide box 1. The first self-locking motor 704 is started, which drives the eccentric wheel 705 to rotate. When the top of the eccentric wheel 705 contacts the guide box 1, the eccentric wheel 705 continues to rotate, which will drive the guide box 1 to move upward.

[0031] The usage method of this embodiment is as follows:

[0032] In use, the operator adds refractory powder additives to the storage bin 3 through the feed hopper 4, and starts the second self-locking motor 1102. The second self-locking motor 1102 drives the second rotating shaft 1103 to rotate, which in turn drives the second screen 1104 to rotate. When the second screen 1104 and the first screen 10 are misaligned, the additives in the storage bin 3 can pass through the first screen 10 and the second screen 1104 into the riser 2. The distance between the sieve holes on the first screen 10 and the second screen 1104 can be adjusted as needed to screen additives of different particle sizes. It is worth noting that the channel is largest when the sieve holes on the first screen 10 and the second screen 1104 are completely aligned, allowing the coarsest particles to pass through. As the misalignment progresses, the channel area decreases as the overlap decreases until it is completely closed.

[0033] Then the additive enters the feed box 1 through the riser 2 and finally flows out of the feed box 1 through the discharge hopper 6. The stepper motor 5 is started, and the stepper motor 5 drives the first rotating shaft 12 to rotate, thereby driving multiple stirring rods 13 to rotate. The additive in the storage box 3 is stirred by multiple stirring rods 13, which can break up the micro powder agglomerates. The operation is simple and convenient for screening and homogenizing additives of different particle sizes, saving time and effort. Finally, the position of the second screen 1104 can be observed by using the transparent plate 8 and the scale 9.
