Description

Technical Field

[0001] The utility model belongs to the technical field of ore cleaning and separation, and particularly relates to an ore cleaning and separation device. Background Art

[0002] After ore mining, impurities such as mud and sand remain on the surface. If they are not cleaned before use, it will affect the quality of product production. Therefore, it needs to be cleaned manually or using a cleaning device before use.

[0003] After searching, the publication number in the relevant field is: CN117102124B, and the patent name is an ore cleaning and separation device, whose structure includes a shell, a feed hopper installed in the shell, and an ore separation mechanism installed in the feed hopper. The ore separation mechanism is used to separate the cleaned ore and mud, and a discharge hopper is installed below it. The discharge hopper is connected to the slurry inlet of the mud-water separation mechanism. The drainage pipe of the mud-water separation mechanism is connected to the water spray pipe. A water pump is installed on the water spray pipe. The water outlet end of the water spray pipe is located above the feed hopper and can spray water into the feed hopper; the ore and water entering from the feed hopper, and the mud generated after separation by the ore separation mechanism enter the mud-water separation mechanism from the discharge hopper for mud and water separation, and the separated wastewater is pumped into the water spray pipe by the water pump through the drainage pipe and flows back into the feed hopper.

[0004] While existing ore cleaning and separation devices can recycle wastewater, reducing water waste and conserving resources by circulating ore for cleaning, their cleaning methods have limitations. Specifically, these devices utilize water spray cleaning at the inlet hopper. This method, due to the accumulation of ore, limits the flushing coverage and often results in incomplete ore cleaning. Furthermore, the cleaned ore is not convenient for stationary liquid separation and multi-stage screening. Therefore, an alternative ore cleaning and separation device is provided to address these technical issues. Utility Model Content

[0005] In view of the problem that the ore cleaning and separation device in the prior art has a limited coverage range of water spray cleaning, resulting in incomplete ore cleaning, the utility model provides an ore cleaning and sorting device.

A large-aperture sieve plate 2 for guiding materials to the coarse ore discharge port 12 and a medium-aperture sieve plate 3 for guiding materials to the fine ore discharge port 13 are rotatably installed in the processing box 1, and the medium-aperture sieve plate 3 is located below the large-aperture sieve plate 2. A small-aperture sieve plate 4 is fixedly installed in the processing box 1, and the small-aperture sieve plate 4 and the sediment discharge port 14 are located in the same horizontal plane, and the small-aperture sieve plate 4 is fixedly installed in the processing box 1. Located below the medium-aperture sieve plate 3, a graded flushing device 5 is installed in the processing box 1. The graded flushing device 5 is used to spray high-pressure and low-pressure water above the large-aperture sieve plate 2 and the medium-aperture sieve plate 3 respectively. A sediment cleaning device 6 is installed in the processing box 1. The sediment cleaning device 6 is used to push the sediment filtered by the small-aperture sieve plate 4 toward the sediment discharge port 14. A synchronous driving device 7 is installed in the processing box 1. The synchronous driving device 7 is used to drive the large-aperture sieve plate 2 and the medium-aperture sieve plate 3 to vibrate, and drive the sediment cleaning device 6 to clean the sediment;

[0032] It should be noted that the graded flushing device 5 includes a high-pressure water pump 51, which is fixedly installed on the upper surface of the treatment box 1, and a water suction pipe 511 is connected between the water inlet end of the high-pressure water pump 51 and the bottom of the inner cavity of the treatment box 1, and the discharge end of the high-pressure water pump 51 is connected to a diversion pipe 512, and either end of the diversion pipe 512 is connected to a high-pressure flushing pipe rack 52, which is fixedly installed in the treatment box 1 and is located above the large-aperture sieve plate 2, and the other end of the diversion pipe 512 is connected to a guide pipe 53, a pressure regulating valve 531 is fixedly installed in the pipeline of the guide pipe 53, and the end of the guide pipe 53 away from the diversion pipe 512 is connected to a low-pressure flushing pipe 54, the low-pressure flushing pipe 54 is fixedly installed in the treatment box 1, and the low-pressure flushing pipe 54 is located between the large-aperture sieve plate 2 and the medium-aperture sieve plate 3;

[0033] Before use, inject clean water into the processing box 1 so that the clean water level is below the small-aperture sieve plate 4, then adjust the pressure regulating valve 531 in the guide pipe 53 to reduce the water pressure in the low-pressure flushing pipe 54 to ensure that the fine ore can slide smoothly in the medium-aperture sieve plate 3, then start the high-pressure water pump 51, and the high-pressure water pump 51 supplies the clean water in the processing box 1 through the diversion pipe 512 through the suction pipe 511 to the high-pressure flushing pipe rack 52 and the low-pressure flushing pipe 54 for spraying. When in use, the ore to be cleaned is put into the processing box 1 from the feed hopper 11, and the ore is first screened by the large-aperture sieve plate 2, and then discharged from the coarse ore discharge port 12 to the processing box 1. During the screening process, the ore is subjected to the continuous high pressure of the high-pressure flushing pipe rack 52 above Flushing, the flushing coverage is larger, and the screened fine material and washed sediment fall onto the medium-aperture sieve plate 3 for re-screening, and the screened sediment falls onto the upper surface of the small-aperture sieve plate 4.

The lower surface of the scraper 64 located at the bottom is in contact with the upper surface of the small-aperture sieve plate 4.

[0035] When any one of the transmission rods 61 rotates, the two transmission chains 63 can be driven to move synchronously through the sprocket 62, thereby driving the scraper 64 to move to the right along the upper surface of the small-aperture sieve plate 4, pushing the sand and gravel filtered from the small-aperture sieve plate 4 to the sediment discharge port 14 and discharging it from the treatment box 1.

At the same time, the driving rod 71 on the right drives the driving rod 71 on the left to rotate under the action of the pulley A73 and the transmission belt A74, and the driving rod 71 on the left uses the cam 711 set thereon to move the medium-aperture sieve plate 3 to realize the active vibration of the medium-aperture sieve plate 3.

[0039] Combine Figure 6 、 Figure 1 and Figure 5 As shown, a pulley B75 is provided on the outer surface of any driving rod 71 and any transmission rod 61. The pulley B75 is located outside the processing box 1. After the two pulleys B75 are connected with a transmission belt B76, when the driving rod 71 rotates, the transmission rod 61 can be driven to rotate through the linkage cooperation between the pulley B75 and the transmission belt B76, thereby driving the mud and sand cleaning device 6 to clean the mud and sand.
