Description

Technical Field

[0001] The present invention relates to the technical field of limestone production, in particular to a limestone screening and crushing device. Background Art

[0002] Lime is one of the important raw materials for industrial production, and limestone is the main material for lime production. Since limestone varies in size during mining, it needs to be crushed before calcining in the later stage to achieve better firing effect and reduce energy consumption.

[0003] A Chinese invention patent with application publication number CN110526601B relates to a high-yield and energy-saving mixed lime kiln, comprising a kiln body, a grate provided in the kiln body, a feeding mechanism provided above the grate, a dividing plate provided between the feeding mechanism and the grate, the dividing plate being inclined, and a plurality of through holes for the passage of raw materials being provided on the dividing plate. The through holes gradually increase in size along the inclination direction of the dividing plate, so that the raw materials introduced into the kiln body by the feeding mechanism are screened by the dividing plate and then fall into the grate for calcination, so that the raw materials falling on the grate are differentiated and processed according to their different volumes, so that the fuel with a larger volume contacts the limestone with a larger volume, the fuel with a smaller volume contacts the limestone with a smaller volume, and the volumes of the fuel and limestone in contact with each other are adapted to each other.

[0004] However, the device has the following problems: the device crushes the lime through a single crushing cone, which is relatively simple and has a poor effect; the device cannot accurately control the inflow and outflow of materials during loading and unloading, which easily leads to incomplete processing. Summary of the Invention

[0005] The purpose of the present invention is to address the shortcomings of the existing technology. By setting up a feeding component, the limestone falls on the loading plate. During the rising process, the smaller limestone falls first through the shaking of the spring and the overall rotation, and the large limestone is stuck in each discharge hole and is impacted and crushed by the conical teeth corresponding to the discharge hole. The limestone falls again during the descending process, thereby solving the problem that the crushing of lime by a single crushing cone is relatively simple and the effect is not good; by setting up a lifting component a and a lifting component b, when the loading plate descends, the lifting component a rises, and the raw material can enter the crushing chamber. When the loading plate rises to a certain position, the lifting component b rises to discharge the small limestone, thereby solving the problem that the material input and output cannot be accurately controlled during loading and unloading, which easily leads to incomplete processing.

[0006] In view of the above technical problems, the technical solutions adopted by the present invention are as follows:

[0007] A limestone screening and crushing device comprises a supporting box body, a material box arranged at the upper end of the supporting box body, a crushing chamber is provided inside the material box, a slide is provided between the supporting box body and the material box, a cavity and a collection chamber are provided in the supporting box body, an oil cylinder is provided in the cavity, a feeding assembly is provided at the upper end of the oil cylinder, the feeding assembly comprises a loading plate, the loading plate is rotatably arranged in the crushing chamber, small limestones falling into the crushing chamber fall down during the rotating and rising process of the loading plate, and large limestones rise under the drive of the loading plate, a crushing assembly is provided at the upper end of the crushing chamber, the large limestones are crushed under the action of the crushing assembly and fall into the collection chamber along the slide seat during the rotating and descending process;

[0008] A lifting component a and a lifting component b are respectively provided on both sides of the material box. The lifting components a and b rise and fall driven by the loading tray. When the loading tray rises and falls, the lifting component a is driven to slide in the opposite direction. When the loading tray rises and falls, the lifting component b is driven to slide in the same direction.

[0009] As a preferred embodiment, the feeding assembly also includes a loading plate, a plurality of springs are provided on the upper end of the loading plate, the upper ends of the springs are fixedly connected to the loading plate, the lower end of the loading plate is rotatably connected to the piston rod of the oil cylinder, a plurality of corresponding discharge holes are provided on the loading plate and the loading plate, and a plurality of sliding blocks are provided on the surrounding side of the loading plate.

[0010] As a preference, a cavity a and a cavity b are respectively provided on both sides of the material box, openings are provided on both the cavity a and the cavity b, and threads are provided on the inner wall of the crushing cavity.

[0011] As a preferred embodiment, the lifting assembly a includes a door panel a slidingly arranged in the cavity a, the cavity a is connected to the lower end of the crushing chamber, the upper end of the door panel a is connected to the wire rope, the upper end of the cavity a is rotatably provided with a roller, the end of the wire rope is provided with a slider, and the slider is slidably arranged on the inner wall of the material box.

[0012] As a preference, the lifting assembly b includes a door panel b slidably arranged inside the cavity b, and a support rod is provided at the upper end of the door panel b, and the support rod is slidably arranged on the inner wall of the material box.

[0013] As a preference, the crushing assembly includes a plurality of conical teeth, and the conical teeth correspond to the discharge holes.

[0015] As a preference, the inclined surface of the slide seat is a smooth surface and forms an angle of 30 degrees with the horizontal plane.

[0016] As a preference, the discharge holes on the loading tray and the loading plate are in an inverted cone shape.

[0017] Beneficial effects of the present invention:

[0018] The present invention provides a feeding assembly. During the rising process, the loading plate drops smaller limestones first due to the shaking of the spring and the overall rotation. Large limestones are stuck in each discharge hole, and the conical teeth corresponding to the discharge hole impact and crush them. The remaining limestones are dropped again during the descending process, thereby solving the problem of lime crushing by a single crushing cone, which is relatively simple and has a poor effect.

[0019] The present invention provides a lifting component a and a lifting component b. When the loading plate descends, the lifting component a rises, and the raw materials can enter the crushing chamber. When the loading plate rises to a certain position, it drives the lifting component b to rise, and the small limestone is unloaded, thereby solving the problem of being unable to accurately control the in and out of materials during loading and unloading, which easily leads to incomplete processing.

[0034] Lifting components a and b are respectively provided on both sides of the material box 2. The lifting components a and b rise and fall driven by the loading tray 52. When the loading tray 52 rises and falls, it drives the lifting component a to slide in the opposite direction. When the loading tray 52 rises and falls, it drives the lifting component b to slide in the same direction.

[0035] like Figure 4 、 6As shown, the feeding assembly also includes a loading plate 53, and a plurality of springs 54 are provided on the upper end of the loading plate 52. The upper end of the spring 54 is fixedly connected to the loading plate 53, and the lower end of the loading plate 52 is rotatably connected to the piston rod 55 of the oil cylinder 51. A plurality of corresponding discharge holes 56 are provided on the loading plate 52 and the loading plate 53, and a plurality of sliding blocks 57 are provided on the circumference of the loading plate 52. During the rising process, the loading plate 53 drops the smaller limestone 6 first through the shaking of the spring 54 and the overall rotation. The large limestone 6 is stuck in each discharge hole 56, and the conical teeth 71 corresponding to the discharge hole 56 impact and crush it, and the remaining limestone 6 is dropped again during the descending process.
