Description

Technical Field

[0001] The utility model belongs to the technical field of ore dressing equipment, and specifically relates to a high-efficiency ore unloading funnel of a ceramic filter with simple structure, high production efficiency, convenient cleaning and long service life. Background Art

[0002] In the mineral processing process, concentrate concentration and dehydration is the last stage of the entire production process. Concentrate dehydration is generally carried out by filtering the concentrated slurry through a ceramic filter and then collecting the concentrate with a scraper.

[0003] At present, when the ceramic filter is unloading ore, in order to prevent the concentrate from being scattered everywhere, a square cylindrical unloading funnel is installed under the ceramic filter to collect the concentrate. However, the square cylindrical unloading funnel with openings at both ends has the following problems: first, the moisture content of the concentrate collected after filtration is relatively high, which makes it easy to adhere to the unloading port and the inner wall of the funnel during unloading, and the square cylindrical unloading funnel with closed side walls cannot directly clean the unloading port and the inner wall of the funnel in time, which easily leads to blockage of the unloading port, affecting the continuous and stable operation of the ceramic filter; secondly, since the unloading funnel uses ordinary iron plates as the side walls, and the inner lining uses rubber and plastic plates, not only is the structural strength low, but the unloading funnel is also easily damaged by the corrosion of the concentrate and its residual reagents, so it is necessary to frequently repair the damaged funnel wall, inner lining, or even directly replace the entire funnel, resulting in a large daily maintenance workload and a high cost for concentrate concentration and dehydration.

[0004] In the prior art, in order to solve the problem that the discharge port and funnel of the filter are easily blocked, there is an anti-blocking bushing with a multifilament filter cloth fixed on the upper edge of the funnel body, so that the bottom of the anti-blocking bushing naturally sags and does not contact the funnel wall, and the bottom of the anti-blocking bushing is an anti-blocking funnel with a closed structure, so that the anti-blocking bushing maintains a certain gap with the funnel wall, and can rely on the gravity of the material itself to prevent the filter cake from piling up, effectively preventing the funnel from being blocked. However, since this anti-blocking funnel only solves the blockage problem of the funnel, and the side wall of its funnel body is still a closed structure, it is difficult to clean the discharge port of the filter machine, which is most likely to be blocked during the concentrate concentration and dehydration process, in a timely manner. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a high-efficiency ore unloading funnel of a ceramic filter which has a simple structure, high production efficiency, convenient cleaning and long service life.

[0006] The utility model is implemented as follows: it comprises a square funnel body with upper and lower openings, the top of the funnel body is provided with a feed port connected with the ore discharge port of the ceramic filter, and the bottom of the funnel body is provided with a discharge port;

[0007] The wall panel of the funnel body is a patterned steel plate, and the inner wall of the funnel body is detachably fixedly connected with an inner lining plate of a polymer material.

The bottom end of the unloading baffle is fixedly connected to the funnel body, and side baffles are respectively fixedly arranged between the two sides of the unloading baffle and the outer wall of the funnel body.

[0009] Furthermore, the inner lining plate is fixedly connected to the side wall of the funnel body by bolts or rivets; the side wall of the funnel body is a patterned steel plate with a thickness of 3 to 7 mm.

[0010] Furthermore, at least two vertical reinforcing rods are arranged at intervals in the cleaning window, and two ends of the reinforcing rods are respectively fixedly connected to the outer walls of the funnel body on the upper side and the lower side of the cleaning window.

[0011] Furthermore, a flexible dust-proof curtain is fixedly arranged on the outer wall of the upper funnel body of the cleaning window, and the dust-proof curtain covers the exposed part of the cleaning window and the lower end of the dust-proof curtain extends to the ore unloading baffle.

[0012] Furthermore, the dustproof curtain is a soft curtain divided into a plurality of strips in the horizontal direction, and magnetic tapes are respectively arranged on both sides of the soft curtain.

[0013] Furthermore, a dust collecting hood is fixedly provided on the outer wall of the upper funnel body of the cleaning window, and the dust collecting hood is connected to the dust suction port of the dust collector through a pipeline.

[0014] Furthermore, the dust collecting hood is horizontally arranged above the cleaning window, and both ends of the dust collecting hood at least extend to the side baffles on both sides.

[0015] Furthermore, longitudinal and / or transverse reinforcing ribs are arranged on the outer wall of the ore unloading baffle, and a vibration motor is fixedly arranged in the middle of the outer wall of the ore unloading baffle.

[0016] Furthermore, the lower part of the funnel body is an inverted frustum-shaped structure, and the discharge port is arranged at the bottom end of the inverted frustum-shaped structure of the funnel body.

[0017] Beneficial effects of the utility model:

[0018] 1. The utility model adopts patterned steel plates as the wall plates of the funnel body to replace the traditional ordinary iron plates, which effectively improves the structural strength of the funnel body; and adopts inner lining plates made of polymer materials to replace traditional rubber and plastic plates, which can effectively slow down the corrosion of concentrate and its residual reagents, and improve the service life of the unloading funnel, thereby reducing the daily maintenance workload and also reducing the cost of concentrate concentration and dehydration.

[0019] 2. The utility model opens a cleaning window on one side of the funnel body, thereby facilitating timely cleaning of the concentrate attached to the discharge port of the ceramic filter and the inner wall of the funnel, thereby avoiding the shutdown problem caused by blockage caused by excessive accumulation of concentrate at the discharge port of the ceramic filter and the inner wall of the funnel, and improving the production efficiency of concentrate concentration and dehydration to a certain extent.

[0021] 4.

The bottom end of the unloading baffle 2 is fixedly connected to the funnel body 1, and side baffles 3 are respectively fixedly arranged between the two sides of the unloading baffle 2 and the outer wall of the funnel body 1.

[0032] The angle between the unloading baffle plate 2 and the horizontal plane is 45-80 degrees, and the top end of the unloading baffle plate 2 is inclined upward and extends to the same height as the middle to the top end of the cleaning window 13 in the vertical direction.

[0033] The inner lining plate 8 is fixedly connected to the side wall of the funnel body 1 by bolts or rivets; the side wall of the funnel body 1 is a patterned steel plate with a thickness of 3 to 7 mm.

[0034] At least two vertical reinforcing rods 4 are arranged at intervals in the cleaning window 13, and the two ends of the reinforcing rods 4 are respectively fixedly connected to the outer wall of the funnel body 1 on the upper side and the lower side of the cleaning window 13. The reinforcing rods 4 can reinforce the side wall strength of the cleaning window 13 in the vertical direction, thereby avoiding the problem of weakening the side wall strength of the funnel body 1 due to the opening of the cleaning window 13.

[0035] A flexible dust-proof curtain 5 is fixedly arranged on the outer wall of the hopper body 1 above the cleaning window 13 , and the dust-proof curtain 5 covers the exposed part of the cleaning window 13 and the lower end of the dust-proof curtain 5 extends to the unloading baffle 2 .
