Description

Technical Field

[0001] This utility model relates to the field of limestone products technology, and in particular to a crushing device for the production of reflective heat-insulating limestone products. Background Technology

[0002] Reflective heat-insulating limestone coating is a type of coating with excellent solar reflectance, near-infrared reflectance, and semi-sphere emissivity. It achieves energy-saving and environmentally friendly effects while meeting the decorative performance requirements of conventional limestone coatings. By incorporating reflective heat-insulating technology into the limestone coating, the coating surface effectively reflects solar radiation heat, thereby reducing the surface temperature of buildings, decreasing air conditioning energy consumption, and improving living comfort.

[0003] In the production process of reflective heat-insulating limestone coatings, limestone must first be crushed. Utility model patent with patent authorization announcement number CN117206050A discloses a limestone crusher.

[0004] However, the above-mentioned device still has some drawbacks in actual use. The most obvious one is that limestone is easy to get stuck in the crushing chamber after entering it. Although the device is equipped with a spring structure to reduce jamming, the gap between the spring structure and the crushing roller is variable, so the crushing effect is not good. At the same time, once jamming occurs, the operator cannot make adjustments, which causes the limestone to remain stuck in the crushing chamber and prevents it from being discharged, thus affecting the normal operation of the work.

[0005] Therefore, it is necessary to invent a reflective heat-insulating crushing device for the production of limestone products to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a crushing device for the production of reflective heat-insulating limestone products, which solves the problems of jamming and inability to transport limestone during the crushing process mentioned in the background art through inclined ribs, impact pressure plates and pushing mechanisms.

[0007] According to one aspect of this disclosure, the following technical solution is provided: a crushing device for producing reflective heat-insulating limestone products, comprising a feed cylinder shell and a crushing roller, and further comprising:

[0008] The crushing cylinder shell is fixedly installed inside the feed cylinder shell by a support member, the crushing roller is rotatably installed inside the crushing cylinder shell, the crushing cylinder shell and the feed cylinder shell are coaxially arranged, and the feed inlet of the feed cylinder shell is connected to the crushing cylinder shell.

The two ends of the telescopic rod are respectively fixedly connected to the outer surface of the impact pressure plate and the inner wall of the feed cylinder housing, and the spring is fixedly sleeved on the surface of the telescopic rod.

[0014] According to at least one embodiment of the present disclosure, a crushing apparatus for producing reflective heat-insulating limestone products has at least two inclined ribs on the surface of the crushing roller at positions between adjacent protrusions, and the inclined ribs are arranged in a spiral shape in the conveying direction of the crushing roller.

[0015] According to at least one embodiment of the present disclosure, in the crushing apparatus for producing reflective heat-insulating limestone products, the side of the impact plate near the crushing roller is arranged in an arc shape.

[0016] According to at least one embodiment of the present disclosure, a crushing apparatus for producing reflective heat-insulating limestone products is provided, wherein the feed inlet is connected to the crushing cylinder shell via a feed pipe.

A sealing plate is fixedly installed at one end of the feed cylinder shell opening. A shaft hole is provided on the surface of the sealing plate for the insertion of the drive shaft of an external drive device. The drive shaft is connected to the crushing roller via a coupling.

[0019] The technical effects and advantages of this utility model are as follows:

[0035] like Figure 1-Figure 5 As shown in the present invention, a crushing device for producing reflective heat-insulating limestone products includes a feed cylinder shell 1 and a crushing roller 3, and further includes:

[0036] The crushing cylinder shell 2 is fixedly installed inside the feeding cylinder shell 1 by a support member. The support member is a common internal support structure in the prior art, which can be a columnar steel pipe or a solid steel support frame, and will not be described in detail here. The crushing roller 3 is rotatably installed inside the crushing cylinder shell 2. The crushing cylinder shell 2 and the feeding cylinder shell 1 are coaxially arranged. The feed inlet 11 of the feeding cylinder shell 1 is connected to the crushing cylinder shell 2. Limestone or other materials that need to be crushed enter the crushing cylinder shell 2 through the feed inlet 11 for crushing.

[0037] To ensure that limestone or other materials that need to be crushed can be crushed by the crushing roller 3, this utility model also includes an impact pressure plate 4. Multiple slots 21 are symmetrically opened on both sides of the crushing cylinder shell 2, and each slot 21 is provided with an impact pressure plate 4.

[0038] Pushing mechanism 5: The feed cylinder shell 1 is provided with pushing mechanism 5 at the position of impact pressure plate 4. Pushing mechanism 5 is used to adjust the distance between impact pressure plate 4 and crushing roller 3, so as to avoid limestone or other materials that need to be crushed from getting stuck in the crushing cylinder shell 2.

[0039] The surface of the crushing roller 3 is provided with multiple protrusions 31 along the length direction, and inclined ribs 32 are fixedly provided on the surface of the crushing roller 3 between adjacent protrusions 31. The inclined ribs 32 play a pushing role to ensure that limestone or other materials that need to be crushed can be discharged smoothly.

[0040] In this embodiment, to facilitate manual adjustment of the distance between the impact plate 4 and the crushing roller 3 according to the jamming position, the pushing mechanism 5 includes a bolt 51, an elastic element 52, and a threaded sleeve 53. Threaded holes are opened on the surface of the feed cylinder housing 1 corresponding to the position of the impact plate 4. The bolt 51 is installed in the threaded hole, and the threaded sleeve 53 is fixedly installed on the outside of the impact plate 4. The threaded sleeve 53 is threadedly connected to the bolt 51 at the corresponding position.

The drive shaft is connected to the crushing roller 3 through a coupling. The external drive equipment can be a motor.

[0047] This utility model provides a protrusion 31 on the crushing roller 3. The protrusion 31 and the impact plate 4 can crush limestone. The crushing roller 3 is also provided with an inclined rib 32. When the crushing roller 3 rotates, the inclined rib 32 can act as a screw conveyor, thereby ensuring that the limestone can move smoothly along the length of the crushing roller 3 to the discharge port of the crushing cylinder shell 2, reducing the jamming of the limestone.

[0048] By rotating bolt 51, bolt 51 can move the impact plate 4 closer to or further away from the crushing roller 3, thereby adapting to the crushing of limestone of different particle sizes. If limestone is stuck in the crushing cylinder shell 2, the stuck limestone can be removed by adjusting the impact plate 4 away from the crushing roller 3.
