Technical Field

[0001] The utility model belongs to the technical field of oil-rich pulverized coal processing, in particular to a raw material impurity removal device for oil-rich pulverized coal processing. Background Art

[0002] Oil-rich coal refers to coal with a tar yield of 7% to 12%. Oil-rich coal is not only coal, but also a coal-based oil and gas resource. Under the condition of in-situ isolation from air, oil-rich coal can be used to preferentially extract scarce oil and gas resources through medium and low temperature pyrolysis to generate pyrolytic semi-coke that can replace anthracite and coking coal. In this industrial chain, granular and powdery oil-rich pulverized coal that is easy to raise dust, easy to spontaneously combust, and cannot be put into the furnace will be produced. The oil-rich pulverized coal needs to be recycled and processed into briquette through a molding process before it can be used again. During the recovery, transportation, and storage of oil-rich pulverized coal, iron impurities are mixed in the oil-rich pulverized coal due to external pollution. Many of these iron impurities are similar in size to fly ash particles, and cannot be completely removed by screening alone, which will affect the quality of briquette products in the future. Therefore, it is necessary to design a raw material impurity removal device for oil-rich pulverized coal processing to solve the problem that the iron impurities in the oil-rich pulverized coal raw materials are not completely removed and affect the product quality. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] The present utility model will be further described below in conjunction with the drawings.

[0015] Such as Figure 1 、 Figure 2An impurity removal device for raw materials in the processing of rich-oil pulverized coal is shown, including a box body 1. A universal wheel 2 is fixedly connected to the bottom of the box body 1, and there is a locking device on the universal wheel 2. An inlet 3 is fixedly connected to the upper end of the box body 1, and an outlet 4 is fixedly connected to the lower end of the box body 1. The inlet 3 is located above the driving roller 72, and the outlet 4 is located below the driven roller 73. A magnetic plate 6 is fixedly connected to the upper side inside the box body 1 through a connecting rod 5. The width of the magnetic plate 6 is the same as the width of the conveyor belt 71. A conveying mechanism 7 is arranged below the magnetic plate 6. A flat plate 8 is fixedly connected to the side of the magnetic plate 6 away from the inlet 3, and the bottom surface of the flat plate 8 is flush with the bottom surface of the magnetic plate 6. A cleaning mechanism 9 is installed on the flat plate 8.

[0016] In order to continuously convey the rich-oil pulverized coal raw materials to the lower part of the magnetic plate 6 and pass through, the conveying mechanism 7 includes a conveyor belt 71. The conveyor belt 71 is sleeved between the driving roller 72 and the driven roller 73. Both ends of the driving roller 72 and the driven roller 73 are rotatably connected to the inner wall of the box body 1 through bearings. A driving motor 10 is installed inside the box body 1 below the conveyor belt 71. Sprockets are installed at one end of the driving roller 72 and the output end of the driving motor 10. The driving motor 10 and the driving roller 72 are driven by a sprocket chain.

[0017] In order to clean the iron impurities adsorbed on the bottom surface of the magnetic plate 6 and prevent the iron impurities on the bottom surface of the magnetic plate 6 from accumulating too much and falling into the rich-oil pulverized coal raw materials, the cleaning mechanism 9 includes a collection box 91, a scraping plate 92, and a telescopic cylinder 93. A through hole 11 is opened on the box body 1. One end of the flat plate 8 away from the magnetic plate 6 passes through the through hole 11 and extends outside the box body 1. The cross section of the flat plate 8 is L-shaped. The telescopic cylinder 93 is fixedly connected to the flat plate 8. The telescopic cylinder 93 can be one of a pneumatic, electric, or hydraulic telescopic cylinder. In this embodiment, the telescopic cylinder 93 is a pneumatic telescopic cylinder. The air source interface of the telescopic cylinder 93 is connected to an air storage tank connected to an air compressor. The moving direction of the telescopic cylinder 93 is parallel to the magnetic plate 6. One side of the collection box 91 is detachably connected to the output end of the telescopic cylinder 93 through a card slot buckle, which is convenient to remove the collection box 91 and clean the iron impurities therein. A scraping plate 92 is fixedly connected to the upper end of the side of the collection box 91 close to the telescopic cylinder 93, and the top end of the scraping plate 92 abuts against the bottom surface of the flat plate 8.

[0018] In this embodiment, the magnetic plate 6 is a plate-shaped electromagnet. When the scraping plate 92 scrapes the iron impurities adsorbed on the bottom surface of the magnetic plate 6 and collects them into the collection box 91, the operator can control the power switch of the electromagnet to be turned off, and then control the output end of the telescopic cylinder 93 to shorten, and take the collection box 91 out of the box body 1 to prevent the iron impurities collected in the collection box 91 from being re-adsorbed by the magnetic plate 6 and affecting the impurity removal effect.

[0019] In order to ensure the adsorption effect of the magnetic plate 6 on iron impurities in the rich-oil pulverized coal raw material and avoid the iron impurities adsorbed by the magnetic plate 6 from contacting the raw material on the conveyor belt, in this embodiment, the distance between the upper side of the conveyor belt 71 and the bottom surface of the magnetic plate 6 is set to 10 cm.

[0020] In order to prevent the rich-oil pulverized coal raw material from adhering to the surface of the conveyor belt 71, it is necessary to continuously clean the surface of the conveyor belt 71. A guide plate 12 is fixedly connected inside the box body 1 on one side of the discharge port 4. A belt brush 13 is fixedly connected to the top end of the guide plate 12, and the belt brush 13 abuts against the lower side of the conveyor belt 71.

[0021] The specific working process of the present utility model is as follows:

[0022] Start the driving motor 10 to drive the driving roller 72 to rotate, and the conveying mechanism 7 starts to operate. Continuously input the rich-oil pulverized coal raw material into the feeding port 3. The conveyor belt 71 transports the rich-oil pulverized coal raw material to pass under the magnetic plate 6. The iron impurities in the raw material are adsorbed by the magnetic plate 6 and separated from the raw material. The operator regularly starts the control switch of the telescopic cylinder 93. The output end of the telescopic cylinder 93 extends, driving the collection box 91 and the scraper 92 to move. The scraper 92 scrapes off the iron impurities adsorbed on the bottom surface of the magnetic plate 6 and collects them into the collection box 91. When the scraper 92 finishes scraping the bottom surface of the magnetic plate 6, the operator can control the power switch of the magnetic plate 6 to be turned off, and then change the air supply direction of the telescopic cylinder 93 through the control switch. The output end of the telescopic cylinder 93 shortens, driving the collection box 91 to gradually move to the outside of the box body 1. The operator removes the collection box 91, cleans the iron impurities therein, and then reconnects the collection box 91 to the output end of the telescopic cylinder 93. The rich-oil pulverized coal raw material after impurity removal treatment is discharged through the discharge port 4 to carry out the next process.
