This allows for adjustment of the baffle height according to actual conditions, effectively preventing slag of different sizes from falling during feeding.

Description

Technical Field

[0001] This utility model belongs to the field of slag crushing technology, specifically relating to an adjustable slag crushing and grading device. Background Technology

[0002] Slag is a solid waste generated from industrial smelting (such as iron and steel, and non-ferrous metal smelting). It contains silicon, calcium, aluminum, and other components. Untreated slag easily occupies land and pollutes the environment, and crushing is a key preliminary step for the resource utilization of slag. Slag crushing is usually carried out in stages according to the characteristics of the raw materials and subsequent uses, with appropriate equipment selected in stages: coarse crushing often uses jaw crushers to process large, hard slag pieces that have just been discharged, crushing them to tens of centimeters in size; medium and fine crushing often uses impact crushers or cone crushers to further refine the slag to centimeters or millimeters to meet different needs—if it is used to produce building aggregates, it is necessary to control the uniformity of particle size; if it is used to extract valuable metals, crushing can increase the specific surface area and improve the efficiency of subsequent sorting. Slag needs to be crushed and classified by slag crushing and grading equipment.

[0003] Currently, existing slag crushing and grading equipment typically requires slag to be fed into the crushing equipment through the feed inlet, and then crushed and graded by the crushing rollers. However, in order to prevent material from falling out of the feed inlet during feeding, traditional slag crushing and grading equipment often installs baffles on the outside of the feed inlet. However, the height of the baffles is usually fixed and cannot be adjusted according to the actual situation. Therefore, when feeding slag of different sizes, it may still fall out, thereby reducing the efficiency of slag crushing and grading. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable slag crushing and grading device, which aims to solve the problem that existing slag crushing and grading devices typically require slag to be fed into the crushing equipment through the feed inlet and then crushed and graded by crushing rollers. However, in order to prevent material from falling out of the feed inlet during feeding, traditional slag crushing and grading devices often install baffles on the outside of the feed inlet. However, the height of the baffles is usually fixed and cannot be adjusted according to the actual situation. Therefore, when feeding slag of different sizes, it may still fall out, thereby reducing the efficiency of slag crushing and grading.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable slag crushing and grading device, comprising a crushing shell, a feed inlet at the top of the crushing shell, a discharge outlet on the surface of the crushing shell, and two first motors installed on the outer wall of the crushing shell, the output ends of the two first motors being connected to crushing rollers;

[0006] A fixed baffle is fixedly connected to the top of the crushing shell, a fixed frame is fixedly connected to the back of the crushing shell, a second motor is installed at the bottom of the fixed frame, a threaded rod is connected to the output end of the second motor, a threaded sleeve is threadedly connected to the outer wall of the threaded rod, a movable block is fixedly connected to the outer wall of the threaded sleeve, a connecting frame is fixedly connected to the outer wall of the movable block, and a movable baffle is fixedly connected to one end of the connecting frame.

[0007] As a preferred embodiment of the adjustable slag crushing and grading equipment of this utility model, a guide rod is fixedly connected to the inner side of the fixed frame, and one end of the movable block is sleeved on the outer wall of the guide rod.

[0008] In a preferred embodiment of the adjustable slag crushing and grading equipment of this utility model, the movable baffle is sleeved on the outer wall of the fixed baffle.

[0009] In a preferred embodiment of the adjustable slag crushing and grading equipment of this utility model, the end of the threaded rod away from the second motor is connected to the fixed frame via a bearing to form a rotating connection structure.

[0010] In a preferred embodiment of the adjustable slag crushing and grading equipment of this utility model, a dust collection box is fixedly connected to the back of the crushing shell, a communication port is provided between the dust collection box and the crushing shell, a protective net is installed on the outer wall of the dust collection box, an exhaust fan is installed on the top of the dust collection box, a filter screen is installed on the inner side of the dust collection box, and a collection box is inserted through the outer wall of the dust collection box.

[0011] In a preferred embodiment of the adjustable slag crushing and grading equipment of this utility model, the collection box is located directly below the filter screen.

[0012] In a preferred embodiment of the adjustable slag crushing and grading equipment of this utility model, the dust removal box and the crushing shell are connected by a communication port.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] With the movable baffle in place, when the height of the baffle needs to be adjusted, the second motor drives the threaded rod to rotate, so that the threaded sleeve connected to the outer wall can drive the movable block to rise and fall along the guide rod. At the same time, the connecting frame connected to the outer wall of the movable block will drive the movable baffle to rise and fall together, so that the height of the baffle can be adjusted according to the actual situation, thereby effectively preventing slag of different sizes from falling when it is fed.

[0015] By setting up a dust collection box, when slag is being crushed inside the crushing shell, the exhaust fan is activated to draw the dust generated inside the crushing shell into the dust collection box through the connecting port. The dust is then filtered by the filter screen and finally falls into the collection box for collection, thus removing the dust generated during slag crushing. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 The present invention provides the following technical solution: an adjustable slag crushing and grading device, including a crushing shell 1, a feed inlet 2 at the top of the crushing shell 1, a discharge outlet 3 on the surface of the crushing shell 1, and two first motors 4 installed on the outer wall of the crushing shell 1, with the output ends of the two first motors 4 connected to crushing rollers 5.

[0025] A fixed baffle 6 is fixedly connected to the top of the crushing shell 1, and a fixed frame 7 is fixedly connected to the back of the crushing shell 1. A second motor 8 is installed at the bottom of the fixed frame 7. A threaded rod 9 is connected to the output end of the second motor 8. A threaded sleeve 10 is threadedly connected to the outer wall of the threaded rod 9. A movable block 11 is fixedly connected to the outer wall of the threaded sleeve 10. A connecting frame 12 is fixedly connected to the outer wall of the movable block 11. A movable baffle 13 is fixedly connected to one end of the connecting frame 12.

[0026] Preferably, a guide rod 14 is fixedly connected to the inner side of the fixed frame 7, and one end of the movable block 11 is sleeved on the outer wall of the guide rod 14. The movable baffle 13 is sleeved on the outer wall of the fixed baffle 6. The end of the threaded rod 9 away from the second motor 8 forms a rotating connection structure with the fixed frame 7 through a bearing.

[0027] In practical use, by setting the movable baffle 13, when it is necessary to adjust the height of the baffle, the second motor 8 drives the threaded rod 9 to rotate, so that the threaded sleeve 10 connected to the outer wall can drive the movable block 11 to rise and fall along the guide rod 14. At the same time, one end of the connecting frame 12 connected to the outer wall of the movable block 11 will drive the movable baffle 13 to rise and fall together, so that the height of the baffle can be adjusted according to the actual situation, thereby effectively preventing slag of different sizes from falling when it is fed.

[0028] Preferably, a dust collector 15 is fixedly connected to the back of the crushing shell 1, a communication port 16 is provided between the dust collector 15 and the crushing shell 1, a protective net 17 is installed on the outer wall of the dust collector 15, an exhaust fan 18 is installed on the top of the dust collector 15, a filter screen 19 is installed on the inner side of the dust collector 15, a collection box 20 is inserted through the outer wall of the dust collector 15, the collection box 20 is located directly below the filter screen 19, and the dust collector 15 and the crushing shell 1 are connected through the communication port 16.

[0029] In practical use, by setting up the dust collection box 15, when the slag is being crushed inside the crushing shell 1, the dust generated inside the crushing shell 1 can be drawn into the dust collection box 15 through the connecting port 16 by starting the exhaust fan 18. Then, it is filtered by the filter screen 19. Finally, the filtered dust will fall into the collection box 20 for collection, thereby removing the dust during the crushing of slag.

[0030] It should be noted that the protective net 17 is used to shield and protect the connection port 16. The protective net 17 can effectively prevent the broken debris from entering the dust collection box 15, while the generated dust can be normally sucked into the dust collection box 15.

[0031] Working principle: First, by setting up the movable baffle 13, when it is necessary to adjust the height of the baffle, the second motor 8 drives the threaded rod 9 to rotate, so that the threaded sleeve 10 connected to the outer wall can drive the movable block 11 to rise and fall along the guide rod 14. At the same time, one end of the connecting frame 12 connected to the outer wall of the movable block 11 will drive the movable baffle 13 to rise and fall together, so that the height of the baffle can be adjusted according to the actual situation, thereby effectively preventing slag of different sizes from falling when it is fed. Then, the slag is fed into the crushing shell 1 from the discharge port 3, and the crushing roller 5 is driven to rotate by the two first motors 4 to achieve crushing. During the crushing process, by setting up the dust collection box 15, when the slag is crushed inside the crushing shell 1, the exhaust fan 18 is started so that the dust generated inside the crushing shell 1 can be sucked into the dust collection box 15 from the connecting port 16. Then, it is filtered by the filter screen 19. Finally, the filtered dust will fall into the collection box 20 for collection, thereby removing dust during the crushing of slag.

[0032] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are 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 modify the technical solutions described in the foregoing embodiments 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.
