Description

Technical Field

[0001] This utility model belongs to the field of raw material processing technology, specifically a crushing and sorting device for sulfur ore raw materials. Background Technology

[0002] In the pretreatment process of sulfur ore raw materials, crushing and sorting are the core links affecting production efficiency and finished product purity. Sulfur ore needs to be crushed first and then sorted and filtered to separate impurity ores from sulfur ore before melting and purification. Existing crushing equipment generates serious dust during operation, polluting the environment and wasting sulfur powder. Metal impurities mixed in the ore (such as iron slag) require additional sorting equipment, making the process cumbersome. Furthermore, it cannot sort the raw materials according to different sizes after crushing for subsequent operations. Therefore, it is necessary to design a device that can sort the crushed raw materials during crushing and avoid dust generation. Utility Model Content

[0003] To address the above technical problems, this utility model provides a device that can sort the crushed raw materials during the crushing process and avoid dust generation, thereby solving the problems of existing raw material processing devices that cannot suppress dust generation and cannot sort the crushed raw materials.

[0004] To solve the above technical problems, the technical solution of this utility model is as follows: a sulfur ore raw material crushing and sorting device, including a box body, the box body being divided into a crushing chamber and a screening chamber from top to bottom, the screening chamber being arranged from left to right as a first collection box, a sorting box, and a second collection box, the sorting box having a first screen and a second screen fixedly connected from top to bottom at an incline, the first screen and the second screen being fixedly connected by a connecting plate, the bottom of the first screen being fixedly connected to a vibrating motor, the bottom of the second screen being fixedly connected to several electromagnetic strips, the bottom of the sorting box having a discharge port, the crushing chamber having two intermeshing crushing rollers rotatably connected, the two crushing rollers being driven by two motors respectively, the top of the crushing chamber having a feed port and a dust removal pipe fixedly connected thereto, the sides of the box body having dust removal boxes fixedly connected to each other, the output end of the dust removal pipe being connected to the dust removal box, and an induced draft fan being installed on the dust removal pipe.

[0005] Furthermore, the inner wall of the sorting box is provided with several protrusions, and the first screen and the second screen are fixedly connected to the protrusions by springs.

[0006] Furthermore, the downward-sloping end of the first screen is located inside the second collection box, and the downward-sloping end of the second screen is located inside the first collection box.

[0007] Furthermore, the dust collection box is divided into a primary filter box, a secondary filter box, and a tertiary filter box by two filter screens with different filtration levels. The primary filter box is connected to the dust collection pipe, and the tertiary filter box has an air outlet at the top.

[0008] This utility model has the following advantages compared with the prior art:

[0009] 1. This utility model combines a crushing device with a sorting device, which can reduce the raw material processing steps and improve work efficiency. By setting up a dust removal pipe and a dust removal box, dust can be collected and treated. By setting up an induced draft fan on the dust removal pipe, a negative pressure can be formed in the crushing chamber, which will draw the dust generated during crushing into the dust removal box, thus avoiding air pollution and the loss of sulfur powder. By setting up a first screen and a second screen, the crushed raw materials can be classified and processed for subsequent processing. By setting up an electromagnetic strip at the bottom of the second screen, iron slag in the raw materials can be adsorbed during the screening process, which provides convenience for subsequent purification operations.

[0010] 2. By setting up a first collection box and a second collection box, raw materials of different sizes after crushing can be classified and processed, which facilitates subsequent operations. By setting up three filter boxes in the dust removal box, dust pollution of the air can be avoided. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] like Figures 1 to 3The sulfur ore crushing and sorting device shown includes a housing 1. For easy material collection, support legs are provided at the bottom of the housing 1. The housing 1 is divided into a crushing chamber 2 and a screening chamber from top to bottom. The crushing chamber 2 has an arc-shaped crushing chamber wall arranged according to the shape of the crushing roller 3. The bottom opening of the crushing chamber 2 is connected to a sorting box 9. The screening chamber is arranged from left to right as a first collection box 10, a sorting box 9, and a second collection box 8. For easy classification and collection, discharge ports are provided at the bottom of both the first collection box 10 and the second collection box 8. To achieve sorting according to material size, a first screen 12 and a second screen 13 are fixedly connected at an angle from top to bottom inside the sorting box 9. The first screen 12 has a larger aperture, and the second screen 13 has a smaller aperture. The first screen 12 and the second screen 13 are inclined in different directions. To achieve simultaneous vibration, the first screen 12 and the second screen 13 are fixedly connected by a connecting plate 15. Next, a vibrating motor 16 is fixedly connected to the bottom of the first screen 12. In order to separate the iron slag in the raw material, several electromagnetic strips 14 are fixedly connected to the bottom of the second screen 13. The electromagnetic strips 14 are evenly distributed at the bottom of the second screen 13. In order to collect the screened raw material, a discharge port 11 is opened at the bottom of the sorting box 9. In order to crush the raw material, two intermeshing crushing rollers 3 are rotatably connected in the crushing chamber 2. Several protrusions are provided on the two crushing rollers 3. The two crushing rollers 3 are driven by two motors 17 respectively. The motors 17 are fixedly connected to the box body 1 through a fixed platform. In order to facilitate feeding, a feed port 4 is opened at the top of the crushing chamber 2 and a dust removal pipe 6 is fixedly connected. The dust removal pipe 6 is located on both sides of the feed port 4. Dust removal boxes 5 are fixedly connected to both sides of the box body 1. The output end of the dust removal pipe 6 is connected to the dust removal box 5. In order to remove dust and avoid air pollution, an induced draft fan 7 is installed on the dust removal pipe 6.

[0017] To make the first screen 12 and the second screen 13 vibrate, a number of protrusions 18 are provided on the inner wall of the sorting box 9. The first screen 12 and the second screen 13 are fixedly connected to the protrusions 18 by springs 19.

[0018] In order to achieve raw material classification and screening, the downward tilted end of the first screen 12 is located inside the second collection box 8, and the downward tilted end of the second screen 13 is located inside the first collection box 10.

[0019] In order to ensure that the air is clean, the dust collection box 5 is divided into a primary filter box 51, a secondary filter box 52, and a tertiary filter box 53 by two filters with different filtration levels. The primary filter box 51 is connected to the dust collection pipe 6, and the tertiary filter box 53 has an air outlet 54 on the top.

[0020] The specific working process of this utility model is as follows:

[0021] When sulfur raw materials need to be crushed, the raw materials are first put into the feed inlet 4. At this time, the motor 17 is turned on, causing the two crushing rollers 3 to rotate inward to crush the raw materials. At the same time, the induced draft fan 7 is turned on. The dust generated during crushing enters the dust collection box 5 through the dust collection pipe 6 and is discharged from the air outlet 54. After crushing, the raw materials fall onto the first screen 12. At this time, the vibration motor 16 is turned on, causing the first screen 12 and the second screen 13 to vibrate simultaneously. Larger raw materials enter the second collection box 8 from the output end of the first screen 12 for collection, while smaller raw materials fall onto the second screen 13. After being screened by vibration, the smaller raw materials are further processed. The material falls from the output end of the second screen 13 into the first collection box 10. At this time, the iron slag in the raw material is adsorbed near the electromagnetic strip 14 under the action of the electromagnetic strip 14. The screened high-quality material flows out from the discharge port 11 below. After a certain period of time, the raw material in the first collection box 10 is cleaned. At this time, the electromagnetic strip 14 is turned off, so that the iron slag attached to the second screen 13 is separated and collected. By following the above steps to crush and sort the raw material, the occurrence of dust can be effectively suppressed. At the same time, sorting the crushed raw material can avoid air pollution and improve work efficiency.
