Description

Technical Field

[0001] The invention belongs to the technical field of ore cleaning equipment, and in particular relates to a conveying equipment for ore spraying and washing. Background Art

[0002] Ore refers to a mineral aggregate from which useful components can be extracted or which has certain properties that can be utilized. It can be divided into metallic minerals and non-metallic minerals. The unit content of useful components in an ore is called ore grade, which is often used to measure the value of an ore. However, the composition of gangue and the amount of harmful impurities in the ore also affect the value of the ore. Ore dressing can enrich the useful components in minerals, reduce the consumption of fuel and transportation in smelting or other processing processes, and make low-grade ores economically utilized.

[0003] In the process of ore production and processing, the ore needs to be crushed first, and then the crushed ore needs to be cleaned before being transported to the transport vehicle. When the ore is washed, the ore is usually washed through a spray pipe on the vibrating screen. In the current cleaning method, the position of the spray pipe is fixed, so the ore can only be washed when it passes through the water column of the spray pipe. However, the washing effect of this washing method is poor, mainly because the ore is prone to overlapping parts during the sliding process, making it difficult to achieve effective cleaning.

[0004] In view of the above-mentioned problems of poor flushing effect and ineffective cleaning due to overlap, the present invention designs a conveying device for ore spray flushing. Summary of the invention

[0005] The object of the present invention is to provide a conveying device for spraying and flushing ore. Through the action of the ore conveying track, the ore roller mechanism and the spraying and flushing mechanism, the material ore is intermittently loaded into the ore roller mechanism, so that it rolls on the ore conveying track, and spraying and flushing are also performed at the same time, so as to realize the function of comprehensive cleaning of the material ore, and solve the above-mentioned problems of poor flushing effect and ineffective cleaning caused by overlapping.

[0006] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0008] As a preferred technical solution of the present invention, the sprocket group is an elliptical structure; two mounting holes are provided on the chains in the sprocket group, and two pins are fixed on the two end faces of each chain plate; the pins cooperate with the inner wall of the mounting hole; each chain on the sprocket group is supported by the two pins and the mounting hole to achieve a stable support effect.

[0009] As a preferred technical solution of the present invention, the chain plate is fixed with limited support seats on both sides of the hinge seat A; the limited support seats are mainly used to ensure that the drum frame is reset to a horizontal state.

[0010] As a preferred technical solution of the present invention, the spray flushing mechanism includes a spray head and a high-pressure fan-shaped nozzle; the mounting frame has a plurality of rows of spray heads and high-pressure fan-shaped nozzles evenly arrayed above the rack track; the high-pressure fan-shaped nozzle has the advantages of a flushing effect and a wider flushing range.

[0011] As a preferred technical solution of the present invention, the mounting frame has several rows of high-pressure fan-shaped nozzles evenly arrayed under the chain plate, and each row of the high-pressure fan-shaped nozzles is oriented inclined upward; increasing the upward flushing angle has the advantage of improving the flushing effect and flushing efficiency.

[0012] As a preferred technical solution of the present invention, a one-way feed baffle is hinged inside the material feed pipe; a limiting ring is fixed on the outside of the one-way feed baffle of the material feed pipe; the function of the limiting ring is to prevent the one-way feed baffle from opening to the outside and can only open to the inside.

[0013] As a preferred technical solution of the present invention, a stepper motor is fixedly installed at the end of the material discharge pipe, and a material blocking circular plate is fixedly installed on the output shaft of the stepper motor; the stepper motor controls the opening and closing of the material discharge pipe; when the drum frame is in feeding, the material blocking circular plate is in a closed state; and when the drum frame is in discharging, the material blocking circular plate is in an open state.

[0014] The present invention has the following beneficial effects:
