Description

Technical Field

[0001] The utility model relates to the field of tailings pond treatment, in particular to a tailings pond high-efficiency ore supply system. Background Art

[0002] The tailings pond is used to store waste materials in the flotation process. The tailings in the tailings pond contain tin metal with a grade between 0.6 and 0.7 and a large amount of ore, which is of great recycling value. The tailings need to be processed by mineral processing to recover tin metal. The process is slurrying of the original ore (tailings in the tailings pond) - gravity separation - flotation - filtration.

[0003] The existing tailings pond is far away from the pulping workshop. First, a dump truck is needed to transport the colloidal tailings from the tailings pond to the ore storage platform 2 of the pulping processing workshop, and then the tailings on the ore storage platform 2 are loaded onto the vibrating screen 3 by a loader for mixing with flushing water for screening and impurity removal (such as Figure 3 As shown in the figure, the screened fine material is transported to the gravity separation section for processing through a slurry pump 5. However, this kind of processing uses a dump truck for long-distance transportation, which will incur a lot of costs. When processing the waste on the belt of the vibrating screen 3, the ore in the slurry pool 4 cannot guarantee the continuity of the feeding operation. Moreover, the processing capacity of the raw ore of a single vibrating screen 3 is limited, and the feeding concentration of the gravity separation workshop cannot meet the production needs. Utility Model Content

[0004] In order to solve the above-mentioned problems, the utility model provides a tailings pond high-efficiency ore supply system.

[0005] The utility model is realized through the following technical solutions:

[0007] Further optionally, the discharge port of the ball mill is transported to the feed port of the drum screen through a circulation pump and a reflux pipe.

[0008] Further optionally, the drum screen is provided with a beating device to prevent the screen from being blocked.

[0009] Further optionally, the beating device includes a beating rod hingedly fixed to the feed port of the drum screen, and an upper and lower driving assembly is provided at the hinge of the beating rod.

DETAILED DESCRIPTION

[0017] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:

[0018] like Figure 1 As shown, a tailings pond efficient ore supply system includes a tailings pond site 1, the tailings pond site 1 is provided with a vibrating screen 3, a slurry pool 4 is provided at the lower part of the vibrating screen 3, the slurry pool 4 is transported to a drum screen 6 for screening through a slurry pump 5, the coarse material of the drum screen 6 is transported to a ball mill 7 for fine grinding and then returned to the drum screen 6 for circulation treatment, and the fine slurry screened by the drum screen 6 is transported to a gravity separation section for treatment through a slurry pipeline 10 and a delivery pump 11.

[0019] like Figure 1 As shown, the discharge port of the ball mill 7 is transported to the feed port of the drum screen 6 through a circulation pump 8 and a reflux pipe 9.

[0020] like Figure 1 As shown, the drum screen 6 is provided with a beating device to prevent the screen from being blocked.

[0021] like Figure 2As shown, the beating device includes a beating rod 62 hingedly fixed to the feed port 61 of the drum screen 6. The beating rod 62 is configured with an internally hollow hard plastic strip plate to prevent it from rigidly contacting the drum screen 6 and damaging the screen. The beating rod 62 is hinged with upper and lower drive components.

[0022] like Figure 2 As shown, the upper and lower driving components include a driving motor 63 fixed to the side of the feeding port 61, and the main shaft of the driving motor 63 is connected to a cam shaft 64 in contact with the root of the beating rod 62, and grease is applied on the cam shaft 64 to extend its service life.

[0023] like Figure 1 As shown, the beating bar 62 is arranged on the top of the screen of the drum screen 6.

[0024] The implementation principle of the high-efficiency ore supply system of the tailings pond in the embodiment of the present application is as follows:

[0025] A vibrating screen 3 is set at the original site of the tailings pond site 1. The tailings on the tailings pond site 1 are directly loaded onto the vibrating screen 3 by a loader. The tailings are mixed with flushing water and vibrated at high frequency by the vibrating screen 3. The colloidal tailings in the tailings are mixed to initially form slurry, which greatly reduces the transportation cost of dump trucks in the past. The large impurities in the slurry are screened out for site treatment, and the fine slurry screened out enters the slurry pool 4 and is transported to the drum screen 6 by the slurry pump 5.

[0026] Through the rotation and screening of the drum screen 6, the initially formed slurry material is mixed for the second time, and the large tailings material screened out enters the ball mill 7 for grinding and refinement, and is transported to the drum screen 6 for circulation treatment through the circulation pump 8, so that the feed concentration requirement entering the gravity separation workshop can be guaranteed. Even when the vibrating screen 3 is shut down for maintenance, the buffered materials in the ball mill 7 can ensure the normal feeding of the drum screen 6, and ensure the continuity of the ore feeding to the gravity separation section through the delivery pump 11;

[0027] When the material in the drum screen 6 blocks the screen and affects its normal operation, it is necessary to start the driving motor 63 of the beating device. The driving motor 63 drives the hinged beating rod 62 up and down through the rotation of the camshaft 64. In this way, the beating rod 62 forms an up and down beating action at the hinge with the feed port 61, and beats the impurities blocked on the screen of the drum screen 6 to loosen it and ensure the normal use of the drum screen 6.

[0028] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
