The ore washing machine can remove clayey materials from the ore, improving its cleanliness and thus increasing the efficiency and beneficiation performance of subsequent processes.

[0003] Existing ore washing machines are inefficient at separating mud and ore, and are prone to clogging when the mud content is high, requiring a large amount of water to rinse for a long time. Utility Model Content

[0004] The purpose of this invention is to provide a drum-type ore washing machine to solve the problem of low ore washing efficiency mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drum-type ore washing machine, including an outer drum, an inner screen cylinder is arranged inside the outer drum, the two are coaxially arranged, and a water spray module is arranged at the axis. A scraper is arranged on the outer side of the inner screen cylinder, the scraper does not contact the inner wall of the outer drum, and a crushing spike is arranged on the inner side of the inner screen cylinder. Both the inner screen cylinder and the outer drum are inclined, and a spiral strip is fixedly connected to the inner wall of both.

[0006] Preferably, the inner screen cylinder includes multiple coaxial connecting rings, all of which are fixed together on multiple annularly arranged rods, with a gap between adjacent rods, and the crushing spikes and scrapers are both fixed on the rods.

[0007] Preferably, the water spray module is a metal pipe, and the side wall of the metal pipe is provided with multiple water spray holes.

[0008] Preferably, the outer roller and the connecting rings at both ends are provided with toothed rings on their outer sides, and are connected to external drive gears through the toothed rings.

[0009] Preferably, a feeding hopper is fixedly connected to the end of the connecting ring at the top.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This utility model discloses a drum-type ore washing machine, which is equipped with an outer drum and an inner screen. Large pieces of soil are crushed by the crushing spikes inside the inner screen and the soil is separated from the ore. Small pieces of soil are driven by scrapers to rub against the inner wall of the outer drum, so that they are ground and refined, making them easier to wash away with water. This ore washing machine effectively improves the washing efficiency of ore. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 A drum-type ore washing machine includes an outer drum 1 and an inner screen cylinder 3 inside the outer drum 1, both coaxially arranged with a water spray module 7 at the axis. A scraper 4 is installed on the outer side of the inner screen cylinder 3, without contacting the inner wall of the outer drum 1. Crushing spikes 6 are installed on the inner side of the inner screen cylinder 3. Both the inner screen cylinder 3 and the outer drum 1 are inclined, and spiral strips 5 are fixedly connected to their inner walls. Ore carrying soil is fed into the inner screen cylinder 3. Large pieces of soil are broken up by the crushing spikes 6 as the drum rotates, while smaller pieces enter the outer drum 1 from the inner screen cylinder 3. The scraper 4 drives the soil to roll, and the friction between the soil and the inner wall refines the soil, which is then washed away by the water flow, achieving effective soil removal with high washing efficiency.

[0019] The inner screen cylinder 3 includes multiple coaxial connecting rings 31, which are collectively fixed to multiple annularly arranged rods 32. A gap is provided between adjacent rods 32 to allow smaller pieces of ore to pass through. The crushing spikes 6 and scrapers 4 are both fixed to the rods 32. A feeding hopper 2 is fixedly connected to the end of the top connecting ring 31 for easy feeding.

[0020] The water spray module 7 is a metal pipe, and multiple spray holes are provided on the side wall of the metal pipe. Water is sprayed from the spray holes into the inner screen cylinder 3.

[0021] The outer roller 1 and the connecting rings 31 at both ends are provided with toothed rings 8 on their outer sides, and are connected to external drive gears through the toothed rings 8. This design facilitates the driving of the outer roller 1 and the inner screen cylinder 3 to rotate respectively.

[0022] Working principle: In this utility model, a drum-type ore washing machine is used. When the ore carrying soil is fed into the inner screen cylinder 3, the large pieces of soil are broken and split by the crushing spikes 6 as it rotates. The smaller pieces enter the outer drum 1 from the inner screen cylinder 3. The scraper 4 drives it to roll. The soil rubs against the inner wall, which refines the soil. Finally, it is washed away by the water flow, thus achieving effective removal of soil.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
