Description

TECHNICAL FIELD

[0001] The utility model relates to ore hopper technical field, concretely is a kind of for ore conveying of concentrator. BACKGROUND

[0002] The hopper plays an important role in connecting between devices in the ore conveying process of concentrator, and there are many positions using the hopper in the ore production process, such as the feeding and discharging of the crusher, the feeding and discharging of the screen, the feeding and discharging of the grinding machine, etc. As a vulnerable part of the concentrator, the liner is replaced frequently during production, and the replacement of the liner is relatively cumbersome. Therefore, some small concentrators weld steel plates outside the hopper after the hopper is worn and the material is leaked, which affects the service life and use effect of the hopper.

[0003] Currently, the hopper used in the concentrator is lined with steel plates or PE liners inside the hopper body. The replacement cycle of these two kinds of liners is about half a year during the production process of the concentrator. If not replaced in time, the hopper body will be worn out, and steel plates need to be welded outside the hopper body to prevent ore from falling, but frequent replacement of steel plates will affect the normal production. At the same time, when repairing the hopper, due to the small space, the repair personnel are easy to be scalded and lack of oxygen when welding. UTILITY MODEL CONTENT

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0020] Please refer to Figs. 1 to 4 A funnel for ore conveying in a concentrator, comprising a feed inlet 1, a conveying bin 2 fixedly installed on the feed inlet 1, ore enters the conveying system through the feed inlet 1 and then slides along the conveying bin 2 to realize the conveying activity of the ore.

[0021] The surface of the conveying bin 2 in contact with the ore is provided with a support mechanism, a mounting frame 11 is fixedly installed on the support mechanism at equal intervals, and a receiving groove 17 is formed in the mounting frame 11, the support mechanism is used for enhancing the structural strength of the conveying bin 2 and preventing deformation.

[0022] By installing a plurality of mounting frames 11 on the surface that is easily impacted and abraded by the ore, when the initial ore moves into the conveying bin 2, a layer of material will be formed in the receiving groove 17, so that the falling ore first impacts the existing layer of material instead of directly impacting the wall surface of the conveying bin 2, and this "material hitting material" mode greatly reduces the direct impact and abrasion on the funnel material, effectively protects the structure of the conveying bin 2, and thus significantly improves the service life of the conveying bin 2.

[0023] The mounting frame 11 is provided with a mounting mechanism, the design of the mounting mechanism enables each mounting frame 11 to be replaced individually, which means that when some or some small squares are abraded or have other problems, only the damaged parts need to be replaced, without replacing all the devices, which not only reduces the maintenance cost, but also reduces the downtime and improves the overall operation efficiency

[0024] The feed inlet 1 is provided with a moving mechanism, the moving mechanism can move the support mechanism and the mounting frame 11, so that there is a gap between the support mechanism and the inner wall of the conveying bin 2 for the material layer to pass through, so that the ore performing the buffering activity can be moved after the conveying is completed, and the discharging effect is ensured.

[0025] The support mechanism comprises longitudinal flat steels 8 and transverse flat steels 9, the longitudinal flat steels 8 and the transverse flat steels 9 are fixedly installed on the surface of the conveying bin 2 in contact with the ore at equal intervals, and an interval groove 10 is arranged between the longitudinal flat steels 8 and the transverse flat steels 9.

[0026] The intermediate groove 10 corresponds to the position and size of the receiving groove 17.

[0027] The longitudinal flat steel 8 and the transverse flat steel 9 are integrally formed or welded. When the support mechanism is attached to the conveying bin 2, the ores can be in the intermediate groove 10 and the receiving groove 17, forming a buffer layer. After use, when the support mechanism is separated from the conveying bin 2, the ores performing the buffering function can smoothly fall through the intermediate groove 10 and the receiving groove 17, and then be discharged from the conveying bin 2.

[0028] The mounting mechanism includes a fixed block 12 and a connecting block 14. The fixed block 12 and the connecting block 14 are fixed by bolts 16. The fixed block 12 is fixedly installed on the transverse flat steel 9. The fixed block 12 is provided with an internal thread groove 13. The connecting block 14 is fixedly installed on the mounting frame 11. The connecting block 14 is provided with a positioning hole 15. The internal thread groove 13 and the positioning hole 15 are matched with the bolts 16.

[0029] Preferably, the bolts 16 are provided with anti-loosening washers to prevent loosening.

[0030] Through the cooperation of the positioning hole 15, the internal thread groove 13 and the bolt 16, each mounting frame 11 can be conveniently disassembled and maintained separately, which is convenient to use.

[0031] The moving mechanism includes a threaded rod 6. The threaded rod 6 is rotatably installed on the sliding rod 3. The threaded rod 6 is provided with a nut pair 5 through threading. One end of the threaded rod 6, away from the feeding port 1, is fixedly installed with a hand wheel 7. The nut pair 5 is fixedly installed with a connecting plate 4 at equal intervals. The connecting plate 4 is fixedly installed with the sliding rod 3. The sliding rod 3 is fixedly connected with the feeding port 1 and the longitudinal flat steel 8.

[0032] By rotating the hand wheel 7, the rotation of the hand wheel 7 causes the threaded rod 6 to rotate, which can cause the nut pair 5 to move up and down. Then, the connecting plate 4 and the sliding rod 3 drive the support mechanism to move synchronously. The support mechanism moves along the vertical direction of the inner wall of the conveying bin 2, so that a gap can be formed between the support mechanism and the outer wall of the conveying bin 2, and the material layer can also be smoothly discharged.

[0033] Preferably, a vibrating device can be provided on the conveying bin 2 to further ensure the discharging effect.

[0034] The central axis of the conveying bin 2 forms an angle of 45° to 70° with the horizontal direction. It is worth noting that the optimal angle needs to be selected according to the material characteristics and production requirements.

[0035] The working procedure of the utility model; ore enters the conveying bin 2 through the feed inlet 1, and slides along the conveying bin 2 with a certain inclination angle (45° to 70°), the design utilizes gravity, promotes smooth flow of ore, and reduces the possibility of blockage.

[0036] In the ore falling process, they first fall into the receiving groove 17 in the mounting frame 11, forming a buffer layer, and the layer has the effect of "material hitting material", that is, the ore falling subsequently will first hit the buffer layer, instead of directly impacting the wall surface of the conveying bin 2, thereby protecting the conveying bin 2 from abrasion.

[0037] When the discharging is completed, the hand wheel 7 can be rotated, the threaded rod 6 is rotated, the nut pair 5 is moved, the connecting plate 4 and the sliding rod 3 are moved, the support mechanism is moved as a whole, and the buffer layer can be smoothly discharged.

[0038] When some mounting frame 11 is abraded or damaged, it can be easily replaced alone by disassembling the bolt 16, without replacing the whole device. The design reduces the maintenance cost and shortens the downtime.

[0039] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
