Abstract
Description
Technical Field
[0001] This utility model relates to the field of refractory material production technology, specifically to a refractory material raw material screening device. Background Technology
[0002] Natural and synthetic high-temperature resistant mineral raw materials, along with various binders and mineralizers that combine refractory aggregates and powders into a whole, are called auxiliary raw materials for refractory materials. These mainly include: refractory clay, siliceous raw materials, dolomite, magnesite, graphite, pyrophyllite, vermiculite, peridotite, serpentine, chromite, high-alumina minerals, zircon, etc. Synthetic refractory raw materials include sintered corundum, synthetic mullite, silicon carbide, etc. In the production process of refractory materials, it is necessary to screen the raw materials. The particle size of the screened raw materials will affect the quality of the product.
[0003] A search revealed that Chinese Utility Model Application No. CN202123432868.3 proposes a refractory material raw material screening device. The utility model description states that "the purpose of setting up a control module and a first weighing module is that the control module compares a first weight value with a preset weight value. When the first weight value is less than the preset weight value, the control module controls the speed regulation module to reduce the vibration frequency of the vibrating motor; when the first weight value is greater than the preset weight value, the control module controls the speed regulation module to increase the vibration frequency of the vibrating motor. Because increasing the vibration frequency of the screening device increases the material throughput when there is a large amount of material, and reducing the vibration frequency of the screening device reduces the energy consumption of the screening device when there is a small amount of material, the applicability of the screening device is improved."
[0004] In this refractory material raw material screening device, the screen and screen frame are connected by bolts for easy screen replacement. However, the screen is continuously subjected to vibration, which causes slight relative movement between the threads of the bolts and nuts, resulting in gradual loosening and poor connection stability, which affects the screening effect. Therefore, a refractory material raw material screening device is proposed to solve the above problems. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-5 The refractory material raw material screening device in this embodiment includes a bin body 1, a cover plate 2 inserted into the top of the bin body 1, a bin door 3 embedded in the front of the bin body 1, a box body 4 placed on the inner bottom wall of the bin body 1, an insert plate extending into the box body 4 fixedly installed on the inner bottom wall of the bin body 1, a slot matching the insert plate is opened inside the box body 4, and a rotating mechanism 5 and a screening mechanism 6 are provided on the bin body 1.
[0023] Specifically, the staff first removes the cover plate 2, then pours the refractory material into the screening mechanism 6, and then uses the rotating mechanism 5 to drive the screening mechanism 6 and the refractory material to vibrate. Smaller refractory materials pass through the screening mechanism 6 and fall into the box 4, while larger refractory materials remain inside the screening mechanism 6. Finally, the box 4 is taken out by opening the door 3. The connection stability is good, which improves the screening effect.
[0024] In this embodiment, the rotating mechanism 5 includes a housing 51, which is fixedly connected to the outer wall of the chamber 1. Two rotating shafts 52 are rotatably mounted on the inner wall of the chamber 1 via a second bearing. The side of each rotating shaft 52 away from the inner wall of the chamber 1 passes through the chamber 1 and extends into the housing 51. Impact rods 53 and synchronous pulleys 54 are fixedly mounted on the outside of each rotating shaft 52. The impact rods 53 are located inside the chamber 1, and the synchronous pulleys 54 are located inside the housing 51. A synchronous belt 55 is installed on the outside of the two synchronous pulleys 54 for common transmission. A motor 56 is fixedly mounted on the inner bottom wall of the housing 51. The output end of the motor 56 is fixedly connected to the side of one of the rotating shafts 52 away from the inner wall of the chamber 1.
[0025] Specifically, by turning on the motor 56, the motor 56 drives one of the rotating shafts 52 to rotate. Through the transmission of the synchronous pulley 54 and the synchronous belt 55, the other rotating shaft 52 also rotates synchronously. The rotating shaft 52 drives the impact rod 53 to collide with the screening mechanism 6.
[0026] In this embodiment, the screening mechanism 6 includes two fixed plates 61, both of which are fixedly connected to the left and right sides of the inner wall of the bin 1. A spring 62 is fixedly installed on the top of the fixed plate 61, a movable plate 63 is fixedly installed on the top of the spring 62, an insert block 64 is fixedly installed on the top of the movable plate 63, a connecting block 65 is sleeved on the outside of the insert block 64, the top of the insert block 64 is flush with the top of the connecting block 65, a groove is provided on the opposite side of the connecting block 65, a filter basket 66 is fixedly installed on the opposite side of the connecting block 65, sliders extending into the bin 1 are fixedly installed on both the front and rear sides of the filter basket 66, a sliding groove matching the slider is provided inside the bin 1, a rotating seat 67 is rotatably installed on the top of the movable plate 63 through a first bearing, a connecting rod 68 is fixedly installed on the outside of the rotating seat 67, and a positioning plate 69 that contacts the insert block 64 is fixedly installed on the outside of the connecting rod 68. The insert block 64 is made of iron, and the positioning plate 69 is made of magnet.
[0027] Specifically, first, the filter basket 66 is placed inside the chamber 1, so that the connecting block 65 is fitted onto the outside of the insert block 64. Then, the rotating seat 67 is rotated, and the rotating seat 67 drives the connecting rod 68 and the positioning plate 69 to rotate to the appropriate position, so that the positioning plate 69 and the insert block 64 are connected and the connecting block 65 is positioned. When the filter basket 66 vibrates, it drives the moving plate 63 to move up and down, and the spring 62 is deformed by force, so the filter basket 66 is not easy to loosen due to vibration.
[0028] The working principle of the above embodiments is as follows:
[0029] First, the staff removes the cover plate 2, then places the filter basket 66 inside the chamber 1, so that the connecting block 65 fits onto the outside of the insert block 64. Then, the rotating seat 67 is rotated, which drives the connecting rod 68 and the positioning plate 69 to rotate to the appropriate position, so that the positioning plate 69 and the insert block 64 are connected and the connecting block 65 is positioned. Then, the refractory material is poured into the filter basket 66. Finally, the motor 56 is turned on, which drives one of the rotating shafts 52 to rotate. Through the transmission of the synchronous pulley 54 and the synchronous belt 55, the other rotating shaft 52 also rotates synchronously. The rotating shaft 52 drives the impact rod 53 to collide with the filter basket 66. When the filter basket 66 vibrates, it drives the moving plate 63 to move up and down. The spring 62 is deformed by the force. Smaller refractory materials pass through the screening mechanism 6 and fall into the inside of the box 4, while larger refractory materials remain inside the screening mechanism 6. Finally, the chamber door 3 is opened and the box 4 is taken out. The filter basket 66 is not easy to loosen due to vibration, and the connection stability is good, which improves the screening effect.
