Description

Technical Field

[0001] This utility model relates to the field of refractory brick production and recycling technology, and in particular to a device for crushing unsintered refractory brick blanks. Background Technology

[0002] Unsintered refractory bricks, also known as refractory brick blanks, are intermediate products in the refractory brick production process that have not yet undergone high-temperature sintering. They are mainly made by mixing refractory raw materials (such as clay, high-alumina bauxite, silica, etc.) in a specific ratio, adding appropriate binders (such as water, organic binders, etc.), and then processing them through molding processes (such as compression molding, extrusion molding). They possess the preliminary shape and certain strength of refractory bricks, but because they have not undergone high-temperature sintering, their structure is relatively loose, and their high-temperature resistance, volume stability, and mechanical strength are far lower than those of the final sintered refractory bricks. While unqualified refractory brick blanks have raw material recycling value, the semi-finished refractory brick blanks already possess a certain strength, resulting in large lumps during re-rolling, making them unsuitable for semi-finished product production. Therefore, a crushing device for unsintered refractory brick blanks is provided. Utility Model Content

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0021] Specific embodiments of the unsintered refractory brick blank crushing device provided by this utility model: Please see Figures 1-6 The unsintered refractory brick blank crushing device includes a pit 1 located underground; a pit cover 2 is provided on the upper side of the pit 1; the pit 1 is located next to the workshop silo; the side walls and bottom walls of the pit 1 are made of concrete; the brick blanks are crushed in the pit 1, and the relatively flat pit cover 2 on the upper side reduces the space occupied in the workshop.

[0022] The pit 1 is equipped with a brick head hopper 3 for accommodating brick blanks, an electromagnetic feeder 4 for receiving and conveying brick blanks, a crusher for crushing brick blanks, and a bucket elevator 7 for lifting the crushed material out of the pit 1. The crusher includes a jaw crusher 5 and a roller crusher 6. The jaw crusher 5 first crushes the brick blanks into small pieces, and the small pieces are then crushed into particles by the roller crusher 6.

[0023] Opening the pit cover 2 allows refractory brick blanks to be added into the blank head hopper 3. The electromagnetic feeder 4 receives the brick blanks falling from the blank head hopper 3 and then conveys them to the jaw crusher 5. The brick blank fragments crushed by the jaw crusher 5 fall into the roller crusher 6. The electromagnetic feeder 4, jaw crusher 5, and roller crusher 6 are installed in the pit 1 via supports. The lower end of the bucket elevator 7 is installed at the bottom of the pit 1. The feed inlet of the bucket elevator 7 corresponds to the discharge outlet of the roller crusher 6, and the discharge outlet of the bucket elevator 7 corresponds to the inlet of the silo. The bucket elevator 7 conveys the crushed material to the silo.

[0024] The pit cover 2 includes two side cover plates 8 parallel to both sides of the pit 1. End cover plates 9 are connected between both ends of each side cover plate 8, and several connecting rods 11 connect the two side cover plates 8. Specifically, angle steel 10 is provided on opposite sides of the side cover plates 8, located at the pit opening of the pit 1. The ends of the connecting rods 11 are connected to the angle steel 10, meaning several parallel connecting rods 11 connect the two angle steels 10. The two ends of the angle steel 10 abut against the end cover plates 9 at both ends.

[0025] The side cover plate 8, end cover plate 9, angle steel 10, and connecting rod 11 are connected as a whole by welding and placed on the upper side of the foundation pit 1. The angle steel 10 can support the central cover plate to ensure full coverage. The side cover plate 8 is located on the ground outside the foundation pit 1, and the angle steel 10 extends into the foundation pit 1 to ensure that the pit cover plate 2 is accurately positioned. The side cover plate 8, end cover plate 9, angle steel 10, and connecting rod 11 are all made of steel. The side cover plate 8 is preferably made of anti-slip steel plate, and the end of the connecting rod 11 is connected to the lower side of the angle steel 10.

[0026] The pit cover 2 has a through hole for the bucket elevator 7 to pass through. Specifically, the upper side of the angle steel 10 has several cover plates 12 surrounding the bucket elevator 7. There are four cover plates 12, all of which are rectangular plates, with each pair having the same shape. The four cover plates 12 are welded together to form a rectangular through hole surrounding the bucket elevator 7. One edge of two cover plates 12 is supported on the upper side of the first end of the angle steel 10. In some embodiments, the cover plates 12 are connected to the side cover plates 8 by welding. In other embodiments, the edges of the cover plates 12 are bolted to the angle steel 10.

[0027] A support cover plate 13 is connected between the two side cover plates 8, and the two ends of the support cover plate 13 are welded to the two side cover plates 8 respectively. A movable cover plate 14 is provided between the support cover plate 13 and the surrounding cover plate 12. The edge of the movable cover plate 14 is supported on the upper side of the angle steel 10, and the edge of the movable cover plate 14 is connected to the angle steel 10 by bolts.

[0028] The movable cover plate 14 is located on the upper side of the jaw crusher 5, and the roller crusher 6 is located on the lower side of the jaw crusher 5; by removing the bolts and opening the movable cover plate 14, the jaw crusher 5 can be observed.

[0029] A feeding cover plate 15 is provided between the side of the supporting cover plate 13 away from the movable cover plate 14 and the end cover plate 9 at the second end of the angle steel 10. The feeding cover plate 15 corresponds to the billet head hopper 3 and is supported and placed on the upper side of the angle steel 10. Removing the feeding cover plate 15 allows brick billets to be fed into the billet head hopper 3.

[0030] To prevent the feeding cover 15 from shifting in a typical support environment, ensure its stability, reduce surface protrusions, and guarantee sealing and ease of opening and closing, this embodiment features two vertically sliding inverted U-shaped lifting handles 16 on the feeding cover 15. Two people can simultaneously operate the lifting handles 16 from both sides of the feeding cover 15 to lift it. When the lifting handles 16 slide upwards, they facilitate gripping and lifting the feeding cover 15. When the lifting handles 16 slide downwards, the protrusion on the upper side of the feeding cover 15 is minimal, having little impact on flatness. The surrounding cover 12, supporting cover 13, movable cover 14, and feeding cover 15 are all made of steel plates, preferably anti-slip steel plates.

[0031] Two limiting plates 17 are provided on the lower side of the pit cover plate 2, symmetrically located on both sides of the feeding cover plate 15. The two limiting plates 17 are welded to the lower sides of the end cover plate 9 and the support cover plate 13, respectively. The limiting plates 17 are provided with transverse limiting holes 18. A T-shaped positioning post 19 is slidably inserted through the lower side of the feeding cover plate 15. Specifically, a vertical plate is connected to the lower side of the feeding cover plate 15, and the T-shaped positioning post 19 is slidably inserted through the lower end of the vertical plate. To ensure the stability of the sliding of the T-shaped positioning post 19, a guide tube is fitted on the side of the vertical plate facing away from the limiting plate 17, outside the T-shaped positioning post 19. The T-shaped positioning post 19 is a cylindrical structure with a T-shaped cross-section.

[0032] A tension spring 20 is connected between the head end of the T-shaped positioning post 19 and the feeding cover plate 15 to bring the T-shaped positioning post 19 closer to the limiting plate 17. The tension spring 20 is sleeved on the outside of the T-shaped positioning post 19, with one end connected to the head end of the T-shaped positioning post 19 and the other end connected to the guide tube.

[0033] Each lifting handle 16 corresponds to two T-shaped positioning posts 19, and the two T-shaped positioning posts 19 respectively cooperate with two limiting plates 17. A traction rope 21 is connected between the head end of the T-shaped positioning post 19 and the lower end of the lifting handle 16. The traction rope 21 is made of non-elastic rope, such as steel wire rope.

[0034] The tension spring 20 causes the T-shaped positioning post 19 to extend into the limiting hole 18 of the limiting plate 17, forming a vertical limit and positioning the feeding cover 15. When the lifting handle 16 is lifted upwards, the lifting handle 16 deforms the tension spring 20 through the traction rope 21, causing the T-shaped positioning post 19 to retract from the limiting hole 18, thus disengaging the feeding cover 15 from the limiting plate 17. When the feeding cover 15 is closed, the T-shaped positioning post 19 cooperates with the limiting plate 17 to achieve positioning, ensuring safety.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative effort, or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
