Description

Technical Field

[0001] This utility model relates to the field of sample reduction machines. More specifically, this utility model relates to a sample reduction device for a coke sample preparation system. Background Technology

[0002] Coke is mainly used in ironmaking, and accurate analysis of its particle size, M40, and M10 is crucial for guiding blast furnace production. Therefore, sample preparation and analysis of coke are necessary. Current coke sample preparation systems all require sample reduction equipment. Bulk material quantitative reduction machines are currently the mainstream equipment; however, most of these machines require manual feeding of materials for quantitative reduction. While this meets the reduction requirements, it is inefficient, labor-intensive, and cannot achieve automated operation. Furthermore, existing bulk material quantitative reduction machines struggle to simultaneously reduce different particle size ranges and quantities, limiting their adaptability in actual production and making operation complex. A single quantitative reduction machine cannot meet different sampling standards, further complicating operation, increasing manual labor intensity, and hindering the ability to adjust the sample size according to actual conditions and needs, thus impeding automation.

[0047] The feeding hopper has its inlet connected to the discharge end of the conveying mechanism;

[0048] The collecting mechanism has multiple fixed positions for placing material trays 2 evenly distributed circumferentially at its upper end. The collecting mechanism drives the material tray 2 at any of the fixed positions to move to connect with the discharge port of the hopper.

[0049] In this embodiment, after the material is fed into the feeding hopper 1, it falls onto the conveying mechanism. The conveying mechanism controls the amount of material falling into the feeding hopper each time, achieving quantitative reduction of the material. The material in the feeding hopper is finally collected by the material tray 2 placed on the collecting mechanism. The conveying mechanism controls the quality of the material conveyed to the feeding hopper each time for reduction. Figure 1 As shown, the reduction device of this utility model also includes a housing. The housing can adopt existing technology, and its specific structure will not be described in detail. Figures 1-4 The structure of the outer shell can be used as one specific implementation method.

[0050] Preferably, as another embodiment of the present invention, in the reduction device of the coke sample preparation system, a dust removal mechanism 3 is provided on the side wall of the material discharge bin 1.

[0051] In this embodiment, after the material enters the material hopper 1 from the feed inlet, a certain amount of dust will be generated. At this time, the dust removal mechanism 3 set on the side wall of the material hopper 1 can remove the dust in the material hopper 1 and prevent the dust from remaining on the inner wall of the material hopper 1.

[0052] Preferably, in another embodiment of this utility model, the conveying mechanism in the reduction device of the coke sample preparation system includes:

[0053] The belt conveyor 4 is horizontally arranged, and the discharge port of the discharge bin 1 is located above its conveyor belt. Two guide plates 5 are spaced apart above the conveyor belt of the belt conveyor 4. The upper end of the guide plate 5 is connected to the discharge bin 1, and its lower end is slidably attached to the conveyor belt of the belt conveyor 4.

[0054] A weighing sensor is installed on the belt conveyor 4;

[0055] Adjustment plate 6 is disposed above the conveyor belt of the belt conveyor 4, and the distance between its lower end and the conveyor belt of the belt conveyor 4 is adjustable.

[0056] In this embodiment, two guide plates 5 are spaced apart above the conveyor belt of the belt conveyor 4. The upper end of the guide plates 5 is connected to the material drop hopper 1. The material drop from the material drop hopper 1 is stably dropped onto the conveyor belt by the guide plates 5. The material on the conveyor belt is between the two guide plates 5. At the same time, the movement of the material is limited by the adjusting plate 6. The adjusting plate 6, the conveyor belt and the two guide plates 5 together form an opening, so that the material can only be conveyed forward through the opening. The material after passing through the opening forms a fixed thickness, thereby ensuring that the material on the conveyor belt can be dropped evenly.

[0057] Preferably, in another embodiment of this utility model, the conveying mechanism in the coke sample preparation system's reducing device further includes:

[0058] An adjustment unit 7 is disposed on the material discharge bin 1 and connected to the adjustment plate 6. The adjustment unit 7 drives the adjustment plate 6 to move up and down.

[0063] In this embodiment, the material falling from the discharge end of the conveying mechanism is allowed to enter the discharge pipe 10 through the guide trough 9, and then finally fall into the material tray 2 at the fixed position below the discharge pipe 10 through the guide pipe 10.

[0067] A drive unit 13 is disposed on the feed pipe 10 and connected to the baffle plate 12. The drive unit 13 drives the baffle plate 12 to move up and down.

[0068] In this embodiment, under the influence of gravity, the material in the feed pipe 10 falls into the material tray 2 and bounces upward. To prevent the material from popping out of the material tray 2, a baffle plate 12 and a guide cylinder 11 are provided. During feeding, the baffle plate 12 and the guide cylinder 11 block the upper opening of the material tray 2. Specifically, after the empty material tray 2 moves below the feed pipe 10, the drive unit 13 drives the baffle plate 12 to move downward and press it against the upper end of the material tray 2, sealing the upper opening of the material tray 2. At this time, the feed pipe 10 feeds material. After the feeding pipe 10 finishes feeding, the drive unit 13 drives the baffle plate 12 to move upward and release the material tray 2.

[0071] In this embodiment, a telescopic cylinder 14 is further provided to seal the connection between the feed pipe 10 and the guide cylinder 11, preventing the material in the feed pipe 10 from flying out from the upper end of the guide cylinder 11 when it falls and rises. The telescopic cylinder 14 can be made of a telescopic tube, which extends and retracts with the movement of the guide cylinder 11.

[0073] A rotating disk 15, on the upper end of which a plurality of the aforementioned material trays 2 are evenly distributed circumferentially;

[0074] The rotary drive unit 16 is connected to the lower middle part of the rotary disk 15 via a transmission connection.

[0078] In this embodiment, an installation groove is formed between the rotating disk 15 and the multiple positioning strips 17, and the lower end of the material tray 2 is stuck in the installation groove to fix the material tray 2 on the rotating disk 15.

[0079] Preferably, as another embodiment of this utility model, in the fractionation device of the coke sample preparation system, the collection mechanism further includes:
