Description

Technical Field

[0001] The utility model belongs to the technical field of crushing equipment, and particularly relates to a crusher for producing glass microspheres. Background Technique

[0002] Glass microspheres are a new type of material with a wide range of uses and special properties developed in recent years. This product has the advantages of light weight, low thermal conductivity, relatively high strength, good chemical stability, etc. Its surface has been specially treated to have oleophilic and hydrophobic properties and is very easy to disperse in the organic material system. During the production process of glass microspheres, glass usually needs to be crushed by a crusher, then screened, and passed through a uniform heating zone at a certain temperature, so that the glass particles are melted and form microspheres under the action of surface tension.

[0003] A glass crushing (pulverizing) device refers to processing and crushing waste glass products into fibrous or powdery forms by means of impact extrusion, pressing, mutual impact, grinding, etc. The processed and crushed glass is a good material for producing glass microspheres, glass mosaics, colored glass balls, glass surfaces, glass bricks, artificial glass marbles, foam glass, etc.

[0004] At present, when crushing waste glass products, the materials cannot be automatically conveyed. When there is a large amount of waste, manual pushing of the materials is required continuously, resulting in a low working efficiency of the entire processing process; in addition, some larger pieces of glass are directly conveyed into the crusher without being pre-crushed, which will lead to poor subsequent crushing effects and thus low crushing efficiency. Content of the Utility Model

[0005] The utility model provides a crusher for producing glass microspheres with a reasonable structural design, good crushing effect and high working efficiency to solve the technical problems existing in the known technology. The utility model can automatically perform the operation of pushing and feeding materials, reducing the labor intensity of workers, and can pre-roll large pieces of glass, with high working efficiency and good crushing effect.

Through the above settings, it is possible to avoid the fragmentation and a large amount of dust generated during the crushing operation from splashing and diffusing into the production workshop, causing environmental pollution.

[0025] A guide mounting seat 10 is fixed to the top of the bracket 1. A transversely extending guide groove 9 is provided on the two opposite side walls of the guide mounting seat 10. Each guide groove 9 is provided with a slider that is slidably connected thereto.

[0026] like Figure 2 As shown, the above-mentioned pushing drive device 7 includes a driving mounting seat 7-1 fixed on the bracket 1, a pushing guide rail 7-7 arranged parallel to the guide groove 9 is fixed on the side of the driving mounting seat 7-1, a driving transverse displacement seat 7-3 is slidably connected to the pushing guide rail 7-7 through a slider, and a pushing plate mounting seat 7-6 for mounting the pushing plate 8 is installed on the driving transverse displacement seat 7-3; it also includes a driving screw 7-2 rotatably connected to the driving mounting seat 7-1, the driving transverse displacement seat 7-3 is connected to the driving screw 7-2 through a nut, and also includes a driving motor 7-5 installed on the driving mounting seat 7-1, and a driving pulley pair 7-4 is installed between the output shaft of the driving motor 7-5 and the end of the driving screw 7-2. Furthermore, in order to facilitate installation, disassembly and maintenance, a pulley shaft is installed at the end of the driving screw 7-2 through a coupling. The above-mentioned pulley shaft is rotatably connected to the driving mounting seat 7-1 through a seat bearing, and the driving pulley pair 7-4 is installed between the pulley shaft and the output shaft of the driving motor 7-5.

[0027] The driving pulley pair 7-4 includes a driving pulley keyed to the output shaft of the driving motor 7-5, and also includes a driven pulley keyed to the pulley shaft installed at the end of the driving screw 7-2, and a closed belt is connected between the driving pulley and the driven pulley.

[0028] like Figure 1 As shown, in order to perform a primary crushing operation on relatively large waste glass before the crushing operation, a plate is provided on the front side of the crushing box 4 above the crushing bottom plate 6, and a plurality of groups of crushing heads 15 are fixedly connected to the bottom surface of the plate. The plurality of groups of crushing heads 15 are short rods and are distributed in a rectangular array. The plurality of groups of crushing heads 15 also include a lifting drive structure 11 for driving the plate on which the plurality of groups of crushing heads 15 are installed to lift and lower the plate. A buffer structure 14 is installed between the lifting drive structure 11 and the plate to provide a buffering effect.

[0029] Further, such as Figure 1As shown, the above-mentioned lifting drive structure 11 includes a linear drive member with its extending end facing downwards and fixedly connected to the top plate of the guiding and mounting seat 10. The linear drive member can be a hydraulic cylinder, a pneumatic cylinder or an electric cylinder. In this embodiment, the above-mentioned linear drive member is a hydraulic cylinder.

With the conveying operation of the conveyor belt, the waste glass falls behind the pushing plate 8 on the crushing bottom plate 6. The driving motor 7-5 is started to drive the driving lead screw 7-2 to rotate, and then drive the pushing plate 8 to move towards the rolling head 15, and then push the waste glass under the rolling head 15. Then, the driving motor 7-5 drives the driving lead screw 7-2 to rotate in the reverse direction, driving the pushing plate 8 to move in the reverse direction to a position that does not affect the lifting and moving of the rolling head 15. The stroke of the pushing plate 8 can be controlled by installing a position sensor on the guiding and mounting seat 10, and a trigger plate adapted to the above-mentioned position sensor is installed on the pushing plate 8.

[0032] The piston rod of the linear drive member in the lifting drive structure 11 extends, driving the buffer structure 14 and a plurality of rolling heads 15 to move downward, and then crushing the waste glass pushed under the rolling head 15, which is convenient for crushing large waste glass into small pieces of glass, and then facilitating subsequent crushing operations. Then, the piston rod of the linear drive member retracts, driving the plurality of rolling heads 15 to move upward to a position that does not affect the pushing operation of the pushing plate 8. After completing the above-mentioned rolling and crushing operation,

[0033] The drive motor 7-5 starts again, driving the drive lead screw 7-2 to rotate forward, thereby driving the pusher plate 8 to move towards the feed inlet of the crushing box 4, and pushing the small pieces of crushed glass that have completed the rolling operation into the crushing box 4 for further crushing operation.

[0034] As Figure 3 and Figure 4 shown, in this embodiment, the above-mentioned crushing roller cutter device 3 includes two groups of parallel rotating roller cutter assemblies 3-4 rotatably connected to the inner cavity of the crushing box 4, and a plurality of groups of crushing inclined baffles 3-3 respectively installed on the inner wall of the crushing box 4 and cooperating with the two groups of rotating roller cutter assemblies 3-4; it also includes a crushing motor 3-1 installed on the bracket 1, the output shaft of the crushing motor 3-1 is selectively connected to one of the rotating roller cutter assemblies 3-4, and a driving gear pair 3-2 is installed between the two crushing motors 3-1.

[0035] As Figure 4 shown, the above-mentioned rotating roller cutter assembly 3-4 includes a rotating shaft member 3-4-1 arranged horizontally and rotatably connected to the crushing box 4, a plurality of groups of mounting cutter discs 3-4-2 are key-connected to the rotating shaft member 3-4-1, and a spacer sleeve 3-4-4 for limiting the mounting cutter discs 3-4-2 and key-connected to the rotating shaft member 3-4-1 is arranged between two adjacent mounting cutter discs 3-4-2. A plurality of groups of crushing cutters 3-4-3 evenly distributed in the circumferential direction are installed on the outer peripheral surface of each mounting cutter disc 3-4-2, and the crushing cutters 3-4-3 are detachably connected to the mounting cutter discs 3-4-2 by screws.

[0036] As Figure 4 shown, in this embodiment, the above-mentioned crushing inclined baffle 3-3 has a trapezoidal structure, each crushing inclined baffle 3-3 is respectively located between two adjacent mounting cutter discs 3-4-2, and an arc groove adapted to the spacer sleeve 3-4-4 is opened at the inner end of each crushing inclined baffle 3-3, and the corresponding crushing inclined baffle 3-3 and spacer sleeve 3-4-4 are in clearance fit.

[0037] Working process:

[0038] The waste glass is transported to the feed end of the crushing bottom plate 6 through the conveyor belt, the drive motor 7-5 is started to drive the drive lead screw 7-2 to rotate, thereby driving the pusher plate 8 to move towards the rolling head 15, and then pushing the waste glass under the rolling head 15. Then, the drive motor 7-5 drives the drive lead screw 7-2 to rotate in the reverse direction, driving the pusher plate 8 to move in the reverse direction to a position that does not affect the lifting movement of the rolling head 15, thereby realizing the pushing operation;

[0039] After the pushing operation is completed, the piston rod of the linear drive in the lifting drive structure 11 extends, driving the buffer structure 14 and multiple groups of rolling heads 15 to move downward, and then crushing the waste glass pushed under the rolling heads 15. The large waste glass is crushed into small pieces of glass. Then, the piston rod of the linear drive retracts, driving the multiple groups of rolling heads 15 to move upward to a position where it does not affect the pushing operation of the pushing plate 8, thus realizing the crushing operation;

[0040] After the crushing operation is completed, the drive motor 7-5 starts again, driving the drive lead screw 7-2 to rotate forward, and then driving the pushing plate 8 to move towards the feed port of the crushing box 4, pushing the small pieces of crushed glass that have completed the rolling operation into the crushing box 4 for further crushing operation. At this time, the rotating roller knife assemblies 3-4 rotating in opposite directions can fully crush the crushed glass that has fallen into the crushing box 4. The filter plate 17 installed in the discharge hopper 18 can filter the glass that has completed the crushing operation. The large-grained glass that does not meet the production requirements is intercepted on the filter plate 17, and the glass powder that meets the requirements falls into the aggregate drawer 19 after passing through the filter plate 17.
