Description

Technical Field

[0001] The utility model relates to the technical field of refractory production, in particular to a dust recovery mechanism for refractory production. Background Technique

[0002] Refractory materials refer to a class of inorganic non-metallic materials with a refractoriness of not less than 1580 °C. Refractoriness refers to the Celsius temperature at which a refractory cone specimen resists the action of high temperature without softening and melting down under no load. However, defining only by refractoriness can no longer comprehensively describe refractory materials, and 1580 °C is not absolute. It is now defined that any material whose physical and chemical properties allow it to be used in a high-temperature environment is called a refractory material.

[0003] According to a dust recovery device for refractory production with the application number 201822264690.8, dust gas is introduced into the first cavity from a dust pipeline, and the dust gas has a certain initial velocity. It contacts the first sieve plate in the first cavity. Larger refractory material particles are blocked by the first sieve plate and fall into the receiving hopper. The remaining dust enters the second cavity, where the dust in the second cavity contacts the second sieve plate. Slightly larger dust particles are intercepted by the second sieve plate and fall into another receiving hopper. The final dust enters the third cavity and contacts the third sieve plate. The third sieve plate intercepts all the dust that does not meet the emission standards, and the purified gas is discharged from the clean gas pipe.

[0004] However, the above dust recovery device has certain deficiencies. First, the dust separation of this device is to filter and classify the dust step by step through the initial velocity of the dust gas. When the dust passes through the sieve plate for filtration, the sieve mesh will block the dust, and then the velocity of the dust will gradually decrease, making the dust unable to be effectively filtered in sequence. And the above device filters the dust in steps from large particle size to small particle size. When the initial velocity of the dust is blocked and reduced by the filter screen, the velocity is not enough to continue entering the cavities with different particle size classifications, resulting in the classification of small particle size dust and large particle size dust together, and the classification effect is poor. For this reason, we propose a dust recovery mechanism for refractory production. Content of the Utility Model

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] Please refer to Figures 1 to 3, the present utility model provides a technical solution: a dust recovery mechanism for refractory material production, including a classification box 1. Inside the classification box 1, there is a fine dust classification chamber 2. Inside the classification box 1 and on one side of the fine dust classification chamber 2, there is a medium dust classification chamber 3. Inside the classification box 1 and on one side of the medium dust classification chamber 3, there is a large dust classification chamber 4. On one side of the classification box 1, a granular discharge box 5 is fixedly installed. Inside the top of the classification box 1, a number of guide rods 12 are slidably installed. Inside the top of the classification box 1, a number of holes matching the guide rods 12 are opened. Among them, the guide rods 12 are located on both sides of the slide plate 6 and do not affect the movement and classification filtration of dust on the top of the slide plate 6. One end of the guide rod 12 extends into the classification box 1 and is fixedly installed with a slide plate 6. Inside the slide plate 6 and above the fine dust classification chamber 2, a fine filter screen 7 is installed. Inside the slide plate 6 and above the medium dust classification chamber 3, a medium filter screen 8 is installed. Inside the slide plate 6 and above the large dust classification chamber 4, a large filter screen 9 is installed. Inside the classification box 1 and on one side of the granular discharge box 5, through grooves 10 are opened. The slide plate 6 passes through the inside of the through groove 10 and extends into the granular discharge box 5. On the outer side of the guide rod 12, a limiting plate 13 is fixedly installed. Above the limiting plate 13 on the outer side of the guide rod 12, a spring 14 is installed. The other end of the guide rod 12 is fixedly installed with a touch plate 15. On the top of the classification box 1, a motor 16 is fixedly installed. The output end of the motor 16 is fixedly installed with a cam 17, and the cam 17 cooperates with the touch plate 15.

[0021] On the top of the classification box 1, there is a dust pipeline 23. Among them, the slide plate 6 is arranged in an inclined state above the fine dust classification chamber 2, the medium dust classification chamber 3 and the large dust classification chamber 4, which is convenient for the movement of dust for filtration and classification through the fine dust classification chamber 2, the medium dust classification chamber 3 and the large dust classification chamber 4. Among them, a heightening seat is installed at the bottom of the motor 16. On the top of the classification box 1, an air inlet hole is provided. On one side of the classification box 1, a controller is provided. Among them, the dust pipeline 23 can directly convey the dust to be treated and recycled to the upper part of the slide plate 6 inside the classification box 1.

[0022] A number of partition plates 11 are fixedly installed at the bottom of the slide plate 6. The lower parts of the fine dust classification chamber 2, the medium dust classification chamber 3, the large dust classification chamber 4 and the granular discharge box 5 are all funnel-shaped. The partition plates 11 are slidably connected with the inner walls adjacent to the fine dust classification chamber 2, the medium dust classification chamber 3 and the large dust classification chamber 4. The function of the partition plates 11 is to prevent the classified dust in the fine dust classification chamber 2, the medium dust classification chamber 3 and the large dust classification chamber 4 from being confused when the slide plate 6 shakes up and down, which affects the classification effect.

[0023] A blanking pipe 18 is fixedly installed at the bottom of each of the fine dust classification chamber 2, the medium dust classification chamber 3, the large dust classification chamber 4 and the particle discharge box 5. A negative pressure box 19 is fixedly installed at the bottom of the classification box 1. One end of each of a number of blanking pipes 18 extends into the interior of the negative pressure box 19. A collection cloth bag 20 is installed at one end of the blanking pipe 18. Negative pressure fans 21 are fixedly installed on both sides inside the negative pressure box 19. A number of box doors 22 are arranged on one side of the negative pressure box 19. Among them, the collection cloth bag 20 is connected and installed to the blanking pipe 18 through a hoop, which is convenient for it to be disassembled from the bottom of the blanking pipe 18 to process the recycled dust. Among them, a flexible support frame is arranged inside the collection cloth bag 20, which can ensure that it is always in an expanded state, facilitating the dust to fall into its interior for collection.

[0024] In summary, when the dust recovery mechanism for refractory material production is in use, the refractory material dust to be recovered and classified is conveyed through the dust pipeline 23 onto the slide plate 6 inside the classification box 1. Subsequently, the motor 16 and the negative pressure fan 21 are simultaneously turned on through the controller. After the negative pressure fan 21 is turned on, negative pressure is generated inside the negative pressure box 19, and then suction is generated inside the fine dust classification chamber 2, the medium dust classification chamber 3, the large dust classification chamber 4 and the particle discharge box 5 through the blanking pipe 18. After suction is generated inside the fine dust classification chamber 2, the fine-grained dust of the refractory material on the slide plate 6 is sucked into the fine dust classification chamber 2 through the fine filter screen 7 and then enters the collection cloth bag 20 through the blanking pipe 18 for collection. At the same time, after the motor 16 is turned on, the cam 17 is driven to rotate, and then the guide rod 12 and the slide plate 6 are driven to move up and down reciprocally through the touch plate 15, so that the accumulated dust can be spread out to facilitate the classification of the dust according to different particle size filter screens, and at the same time facilitate the dust to move obliquely in sequence. Finally, after the largest particle size dust is filtered by the large filter screen 9, the large particles of refractory material enter the particle discharge box 5 through the through groove 10 and then fall into the collection cloth bag 20 for collection, and the classification and recovery can be completed. After the recovery is completed, the motor 16 and the negative pressure fan 21 are turned off through the controller, and then the box door 22 is opened and the hoop is loosened to disassemble the collection cloth bag 20 from one end of the blanking pipe 18, which is convenient for processing the classified refractory material dust.
