Description

Technical Field

[0001] The utility model relates to the technical field of building material crushing, in particular to a crushing device for building material raw materials. Background Art

[0002] Crushing equipment for building materials typically refers to industrial machinery used to break large blocks of material into smaller pieces or powders. These devices are widely used in industries such as mining, building materials, and chemicals, and are crucial for processing raw materials such as limestone, gypsum, cement clinker, bricks, and stone.

[0003] Existing publication number CN214554176U discloses a device for crushing raw building materials, comprising a box body, a partition fixedly mounted inside the box body, a hopper fixedly mounted on the top of the box body, and two sets of crushing blades rotatably mounted on one side outer wall of the partition body and one side inner wall of the box body. This device for crushing raw building materials can shake the screen up and down during crushing, which, on the one hand, avoids the possibility of blockage during material discharge and effectively improves material discharge efficiency. On the other hand, it can throw the building materials remaining on the screen upward and then re-crush them with the crushing blades, avoiding the need for manual collection and re-feeding into the device for crushing, effectively improving the crushing efficiency and quality.

[0004] It has been found that the above-mentioned device still has some shortcomings. First, when the above-mentioned device crushes the raw materials of building materials, it uses a screening net to throw the large particles of building materials upward for secondary crushing. Due to the different types of building materials and the different weights of building materials, when the screening net is thrown upward, the heavier building materials may not achieve the effect of secondary crushing due to insufficient throwing force. The lighter building materials may be entangled with the rotating crushing knife due to excessive throwing force, causing the screening net to contact and entangle, resulting in damage to the device. In addition, when the moisture content of the building materials is high, the screening net may stick to the crushing efficiency, resulting in reduced crushing efficiency and even clogging the equipment, which is inconvenient in actual use.

[0005] Therefore, it is necessary to provide a new crushing device for building material raw materials to solve the above technical problems. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides a device for crushing raw materials of building materials.

[0007] The utility model provides a crushing device for building material raw materials, comprising: a box body, wherein a crushing mechanism 1 and a crushing mechanism 2 are respectively rotated from top to bottom inside the box body, and the crushing spacing of the crushing mechanism 1 is larger than the crushing spacing of the crushing mechanism 2; an independent rectangular cavity is opened inside the box body, and a drying component is arranged in the rectangular cavity;

[0008] The drying assembly includes a plurality of heating plates and a plurality of heating tubes. The plurality of heating plates are arranged in a rectangular cavity, and the plurality of heating tubes are inserted between the plurality of heating plates.

[0009] Preferably, a drive assembly is provided between the pulverizing mechanism 1 and the pulverizing mechanism 2, and the drive assembly is located on the outside of the box. The drive assembly includes a drive motor, a synchronous wheel 1, a synchronous wheel 2 and a synchronous belt. The drive motor is fixed on the outside of the box, the rotor of the drive motor is connected to one side of the synchronous wheel 1, and the surfaces of the synchronous wheel 1 and the synchronous wheel 2 are both engaged with the inner surface of the synchronous belt.

The axes of the two pulverizing rollers are respectively fixed on the surfaces of the two rotating columns, and one end of the two rotating columns rotates on the inner wall of the box. The other end of one of the rotating columns passes through the surface of the box and extends to the outside of the box, and the end of the rotating column passing through the surface of the box is fixedly connected to one side of the synchronous wheel.

[0011] Preferably, two opposing inclined blocks are fixed inside the box, and the crushing mechanism 2 is located between the two inclined blocks. The crushing assembly 2 includes two rotating columns 2 and two crushing rollers 2. The axes of the two crushing rollers 2 are respectively fixed on the surface of the rotating column 2.

[0015] Compared with the related art, the crushing device for building material raw materials provided by the utility model has the following beneficial effects:

[0016] 1. The first and second crushing mechanisms rotate from top to bottom inside the box, and the crushing spacing of the first crushing mechanism is larger than that of the second crushing mechanism. Multi-stage crushing is adopted, and the crushing spacing is gradually reduced. This makes it possible to achieve better crushing effects on building materials and has a wider range of applications. It solves the problem that when the screening net is thrown upward, heavier building materials may not achieve the effect of secondary crushing due to insufficient throwing force, and lighter building materials may be thrown too hard, causing the screening net to come into contact with the rotating crushing knife and become entangled, resulting in damage to the device.

[0026] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0027] Please refer to Figures 1 to 7 ,in, Figure 1 This is a schematic diagram of the overall structure of the crushing device for building material raw materials provided by the utility model; Figure 2 This is a schematic diagram of the overall main structure of the device for crushing building material raw materials provided by the utility model; Figure 3 It is a structural diagram of the drive component part; Figure 4 It is a structural diagram of the synchronous belt; Figure 5 This is a schematic cross-sectional view of the overall structure of the device for crushing building material raw materials provided by the present invention; Figure 6 It is a structural diagram of the drying component; Figure 7 Schematic diagram of the connection structure between several heating plates.

[0028] In the specific implementation process, Figures 1 to 7 As shown, it includes a box body 1, and a crushing mechanism 1 and a crushing mechanism 2 rotate from top to bottom inside the box body 1, and the crushing spacing of the crushing mechanism 1 is larger than the crushing spacing of the crushing mechanism 2. An independent rectangular cavity 14 is opened inside the box body 1, and a drying component is provided in the rectangular cavity 14.

[0029] The drying assembly includes a plurality of heating plates 4 and a plurality of heating tubes 41. The plurality of heating plates 4 are arranged in a circle in the rectangular cavity 14, and the plurality of heating tubes 41 are inserted between the plurality of heating plates 4.

[0030] It should be noted that the crushing mechanism 1 and the crushing mechanism 2 are distributed in a gradually shrinking manner from top to bottom inside the box 1. The crushing spacing of the crushing mechanism 1 is larger than the crushing spacing of the crushing mechanism 2, and the crushing spacing is gradually reduced. On the one hand, the working intensity of the crushing blade is reduced, making the crushing blade less likely to be damaged. On the other hand, multi-stage crushing makes the crushing effect better and the crushing degree better.

[0031] It should be further explained that the drying component is located in an independent rectangular cavity 14. By setting up the drying component, the two functions of drying and crushing are compactly integrated, which not only maintains the compactness of the device but also does not affect the performance of their respective functions. In addition, the crushing mechanism 1 and the crushing mechanism 2 will be dried by the drying component during crushing. Due to the drying of the drying component, the moisture content of the raw materials of the building materials is appropriate, and they can be crushed more evenly and efficiently, which helps to obtain finished products with more uniform particle size and better quality. At the same time, it also protects the crushing equipment and extends the life of the equipment.

[0032] It should be further explained that during drying, the heating tube 41 is connected to an external power source to transfer heat to the heating plate 4 for heating. Several heating plates 4 are arranged in a circle in the rectangular cavity 14 so that the raw materials of the building materials can be heated more evenly during drying.

[0033] refer to Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 As shown, a drive assembly is provided between the pulverizing mechanism 1 and the pulverizing mechanism 2, and the drive assembly is located on the outside of the box body 1. The drive assembly includes a drive motor 12, a synchronous wheel 121, a synchronous wheel 2 3 and a synchronous belt 13. The drive motor 12 is fixed on the outside of the box body 1, and the rotor of the drive motor 12 is connected to one side of the synchronous wheel 121, and the surfaces of the synchronous wheel 121 and the synchronous wheel 2 3 are both engaged with the inner surface of the synchronous belt 13.

[0034] The pulverizing mechanism 1 includes two relatively distributed pulverizing components 1, and the two pulverizing components 1 each include a rotating column 122 and two pulverizing rollers 123. The axes of the two pulverizing rollers 123 are respectively fixed to the surfaces of the two rotating columns 122. One end of the two rotating columns 122 rotates on the inner wall of the box body 1. The other end of one of the rotating columns 122 passes through the surface of the box body 1 and extends to the outside of the box body 1, and the end of the rotating column 122 passing through the surface of the box body 1 is fixedly connected to one side of the synchronous wheel 121.

[0035] Two opposing inclined blocks 15 are fixed inside the box body 1, and the crushing mechanism 2 is located between the two inclined blocks 15. The crushing mechanism 2 includes two relatively distributed crushing components 2, and the crushing component 2 includes two rotating columns 2 31 and two crushing rollers 2 32. The axes of the two crushing rollers 2 32 are respectively fixed on the surface of the rotating column 2 31. One end of the two rotating columns 2 31 rotates on the inner wall of the box body 1, and the other end of one of the rotating columns 2 31 passes through the surface of the box body 1 and extends to the outside of the box body 1, and one end of the rotating column 2 31 passing through the surface of the box body 1 is fixedly connected to one side of the synchronous wheel 2 3.

[0036] A mounting plate 11 is fixed to the outside of the box body 1 , a driving motor 12 is fixed to the top of the mounting plate 11 , and one end of a synchronous belt 13 passes through the surface of the mounting plate 11 and extends to the bottom of the mounting plate 11 .

[0037] It should be noted that the drive motor 12 in the drive assembly drives the synchronous wheel 121 to rotate, and the synchronous wheel 121 and the synchronous wheel 2 3 are both engaged with the inner surface of the synchronous belt 13. When the synchronous wheel 121 rotates, the synchronous belt 13 is driven to rotate, thereby driving the synchronous wheel 2 3 to rotate, and the other side of the synchronous wheel 121 is connected to the crushing mechanism 1, and one side of the synchronous wheel 2 3 is connected to the crushing mechanism 2. The crushing mechanism 1 and the crushing mechanism 2 are driven to rotate at the same time through a drive assembly. The unified drive ensures the synchronization of the rotation speeds of the crushing mechanisms 1 and 2, realizes the continuous processing flow of building material raw materials from coarse crushing to fine crushing, and improves the overall production efficiency.

[0038] It should be further explained that two relative inclined blocks 15 are fixed inside the box body 1. The establishment of the inclined blocks 15, on the one hand, can enable the raw materials of the building materials to smoothly reach the position of the secondary crushing during the first crushing, and slide down along the position where the two inclined blocks 15 are recessed inward, thereby reducing the problem that a large number of raw material particles of the building materials remain inside the box body 1, resulting in the inability to carry out secondary crushing.

[0039] refer to Figure 1 、 Figure 2 、 Figure 5 As shown, a plurality of support columns 16 are fixed to the bottom of the box body 1 , a feed port 2 is provided on the top of the box body 1 , and a cover plate 21 is rotated at the top opening of the feed port 2 .

[0040] A discharge port 5 is fixed to the bottom of the box body 1 , and a valve 51 for controlling discharge of materials is fixed to the surface of the discharge port 5 .

[0041] It should be noted that a number of support columns 16 are equidistantly distributed at the four corners of the box 1 for supporting the entire device.

[0042] It should be further explained that when the raw materials of building materials are crushed, the raw materials of building materials are put into the feed port 2 set at the top of the box body 1, and after being crushed, they reach the discharge port 5 fixed at the bottom of the box body 1, and are collected from the discharge port 5. The speed of collection is controlled by turning the valve 51.

[0043] It should be further explained that the feed port 2 is fixed at the top of the box body 1, and the rotatable cover 21 can prevent a large amount of dust generated during the crushing process from being scattered into the environment outside the device and causing pollution to the external environment. The opening of the feed port 2 can be blocked and closed during the crushing process.

[0044] The working principle provided by the present invention is as follows: when in use, the drive motor 12 is started, and under the action of the drive motor 12, the crushing roller 1 123 and the crushing roller 2 32 are driven to rotate synchronously to crush the building material raw materials, and when the building material raw materials with a high moisture content are crushed, the multiple heating tubes 41 in the drying component are started, and the multiple heating tubes 41 will heat the multiple heating plates 4, so that the building material raw materials are dried and kept dry while being crushed, so that the moisture content of the building material raw materials is appropriate and they are crushed efficiently, which helps to obtain finished products with more uniform particle size and better quality.

[0045] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0046] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention.
