Description

Technical Field

[0002] The reduction of global resources is driving the steel industry to reuse scrap steel resources, which has become an important trend in today's industrial development. Metal debris generated during machining can be reshaped and its density increased through specific processing equipment such as an iron filings briquetting machine. This high-density metal cake is not only convenient for storage and transportation, but also can more effectively improve the recovery efficiency of iron elements when mixed with molten steel or molten iron.

[0003] In the prior art, the iron filings briquetting feeding mechanism includes a mounting column, a feeding box and a top cover. The feeding box is arranged on the mounting column, and a feeding cavity and a storage cavity that communicate with each other are formed in the feeding box.

Detailed implementation mode

[0025] In order to make the technical means, creative features, achieved purposes and functions of the present utility model clearer and easier to understand, the present utility model will be further described below in conjunction with the accompanying drawings and specific implementation modes:

[0026] Such as Figures 1 to 2As shown in the figure, the utility model provides an automatic quantitative feeding device for iron filings pressing cakes, which includes: a housing 1, a feeding mechanism 2, a crushing mechanism 3 and a quantitative discharging mechanism 4. The housing 1 includes: a front baffle 11, a rear baffle 12, a first side plate 13 and a second side plate 14. The front baffle 11, the rear baffle 12, the first side plate 13 and the second side plate 14 enclose a discharging cavity. The feeding mechanism 2 is arranged at the top of the discharging cavity. The feeding mechanism 2 includes: a feeding funnel 21, a first discharging port 22 and a partition plate 23. The top of the feeding funnel 21 is respectively connected to the front baffle 11, the rear baffle 12, the first side plate 13 and the second side plate 14. The bottom of the feeding funnel 21 is connected to the first discharging port 22. A partition plate 23 is arranged below the first discharging port 22. A discharging hole is opened in the middle of the partition plate 23, and the discharging hole is communicated with the first discharging port 22. A crushing mechanism 3 is arranged below the partition plate 23. The crushing mechanism 3 includes: a rotary crusher 31, a driver 32 and a first discharging plate 33. The bottom end of the rotary crusher 31 is connected to the output end of the driver 32. The rotary crusher 31 is rotatably installed on the first discharging plate 33. The first discharging plate 33 is installed on the rear baffle 12 through a bending cylinder 34. The components of the driver 32 are installed in the bending cylinder 34. A second discharging plate 5 and a third discharging plate 6 are arranged below the first discharging plate 33. A second discharging port 8 is enclosed between the front baffle 11, the rear baffle 12, the second discharging plate 5 and the third discharging plate 6. A quantitative discharging mechanism 4 is arranged below the second discharging plate 5 and the third discharging plate 6. The quantitative discharging mechanism 4 includes: a sliding mechanism 41, a telescopic driving mechanism 42, a storage box 43 and a support plate 44. The sliding mechanism 41 is installed below the second discharging port 8. The telescopic driving mechanism 42 is located on one side of the sliding mechanism 41. The output end of the telescopic driving mechanism 42 is connected to the sliding mechanism 41. The sliding mechanism 41 is rotatably connected to the storage box 43. The driving telescopic mechanism is used to drive the sliding mechanism 41 to block the second discharging port 8, or drive the storage box 43 to be vertically aligned with the second discharging port 8. The storage box 43 and the driving telescopic mechanism are both installed on the support plate 44, and the support plate 44 is fixed to the rear baffle 12. Pour the iron filings into the feeding funnel 21. The iron filings fall into the crushing mechanism 3 through the first discharging port 22. The rotary crusher 31 grinds the iron filings into fine particles. The processed iron filings fall onto the first discharging plate 33. The first discharging plate 33 is high in the middle and low at both ends. The iron filings slide down along both ends of the first discharging plate 33 and finally fall into the storage box 43. The telescopic driving mechanism 42 pushes the sliding mechanism 41 to block the second discharging port 8, and at the same time, the storage box 43 is pushed out of the support plate 44 and turned over to pour out a quantitative amount of iron filings.

[0027] The upper surface of the first discharging plate 33 is an arched structure, the middle of the arched structure bulges upward, and the rotary crusher 31 is installed in the middle of the arched structure. The arched structure is used for the iron filings to slide down along both ends of the first discharging plate 33 after being ground.

[0028] The rotary crusher 31 includes a rotary shaft 311 and crushing blades 312. The crushing blades 312 are provided on the rotary shaft 311, and the rotary shaft 311 is vertically aligned with the first discharge port 22.

[0029] The sliding mechanism 41 includes a groove plate 411, a sliding plate 412 and a pushing plate 413. There are two groove plates 411, which are arranged mirror-symmetrically. The two groove plates 411 are respectively fixedly connected to the front baffle 11 and the rear baffle 12. The groove plate 411 is provided with a chute, and the chute straddles the second discharge port 8. A slidable sliding plate 412 is arranged in the chute. A pushing plate 413 is connected below the sliding plate 412. The pushing plate 413 is fixed to the output end of the telescopic driving mechanism 42. The pushing plate 413 is used to install a rotatable storage box 43 and control the sliding of the sliding plate 412 in the chute. When the storage box 43 is filled with iron filings, the telescopic driving mechanism 42 pushes the pushing plate 413. The sliding plate 412 slides in the groove plate 411. When the storage box 43 is pushed out of the support plate 44, the sliding plate 412 just blocks the second discharge port to prevent excess iron filings from being discharged from the second discharge port.

[0030] The pushing plate 413 is provided with a connecting rod 414, and the connecting rod 414 is hinged to one end of the storage box 43. When the storage box 43 is pushed away from the support plate 44, the storage box 43 can be turned over at the hinge.

[0031] The driver 32 includes a first bevel gear, a second bevel gear and a motor 321. The motor 321 is installed on the outer side surface of the rear baffle 12. The output shaft of the motor 321 extends fixedly into the bent cylinder 34 and is fixed to the second bevel gear. A first bevel gear is meshed with the second bevel gear, and the first bevel gear is fixed to the rotary crusher 31. The cooperation of the first bevel gear and the second bevel gear enables the motor 321 to drive the rotary crusher 31 to rotate.

[0032] A fourth discharge plate 7 is provided below the support plate 44. The installation end 72 of the fourth discharge plate 7 is connected to the first side plate 13. The fourth discharge plate 7 is provided with a material guiding end 71 and an installation end 72. The position of the material guiding end 71 is lower than the position of the installation end 72. A third discharge port 9 is formed between the material guiding end 71 and the second side plate 14. When the storage box 43 is turned over to pour out the iron filings, the iron filings slide down along the fourth discharge plate 7 and are discharged from the third discharge port 9.

[0033] An extension plate 45 is fixed to the end of the support plate 44 close to the third discharge plate 6. After being connected to the support plate 44, the extension plate 45 slopes downward and is used to support the storage box 43. When the storage box 43 is pushed to the extension plate 45, it flips. Since the edge height of the storage box 43 is not high, the iron filings can be dumped after flipping. The inclination angle of the extension plate 45 is relatively large, so the iron filings can be dumped out. The extension plate 45 also has the function of guiding the storage box 43 to return to its position. When the storage box 43 returns to its position, the extension plate 45 guides the movement of the storage box 43 and then guides it onto the support plate 44 to realize the reset of the storage box 43.

[0034] The surface of the extension plate 45 and the surface of the support plate 44 are transitioned through a first arc surface 46. A second arc surface 47 is formed at the lower corner of the end of the storage box 43 close to the push plate 413. The second arc surface 47 has a guiding function to prevent the storage box 43 from being stuck by a corner of the extension plate 45 when the telescopic driving mechanism 42 pulls the storage box 43 back.

[0035] A limiting plate 48 is fixed to the bottom of the groove plate 411. A notch is formed at the upper corner of the end of the storage box 43 close to the push plate 413. The limiting plate 48 is used to block the notch. When the telescopic driving mechanism 42 pulls the storage box 43 back to the second discharge port, the notch of the storage box 43 can easily enter below the second discharge port. Finally, the notch of the storage box 43 is caught by the limiting plate 48 so that the iron filings will not leak from beside the storage box 43 when discharged from the second discharge port 8.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
