Description

Technical Field

[0001] This utility model relates to the field of heavy medium separator technology, and in particular to the coal discharge mechanism of a shallow trough scraper heavy medium separator. Background Technology

[0002] Shallow trough scraper heavy media separators are widely used in coal preparation plants as the main equipment for lump coal separation. They are suitable for heavy media coal preparation plants for separating lump coal and removing gangue. They have high separation efficiency and large processing capacity, making them one of the effective separation equipment for difficult-to-separate coals. With the increase in coal production and the increase in the proportion of thermal coal entering the washing process, the shallow trough scraper heavy media separation method has become the preferred method for thermal coal separation (especially lump coal separation). In newly built coal preparation plants, shallow troughs have basically replaced traditional heavy media lump coal separation equipment such as vertical rollers and inclined rollers.

[0003] A search revealed Chinese Patent Publication No. CN201220135501.7, which includes a support, a coal discharge mechanism, and a drive mechanism. The coal discharge mechanism is located inside the gangue discharge system of the shallow trough scraper heavy medium separator, above the overflow weir. It mainly consists of a coal discharge chain, a sprocket shaft, a coal discharge sprocket, and a coal discharge scraper. The coal discharge chain is a closed chain, with two chains forming a pair. Each pair of coal discharge chains is connected as a whole by a chain connecting shaft and meshes with the coal discharge sprocket. The coal discharge sprocket is fitted onto the sprocket shaft. The sprocket shaft is fixed to the support and connected to the transmission shaft of the drive mechanism. The coal discharge scraper is suspended on the chain connecting shaft. The drive mechanism is fixed to the support, which is an integral structure suspended on the feed side and the coal discharge side of the separator trough. This utility model has a simple and reliable structure, is easy to adjust and control, and has low manufacturing costs. However, in this application, when the scraper inside the device drives the internal gangue to be discharged, it easily carries out a large amount of suspension, which can easily lead to waste of resources. Utility Model Content

[0004] The purpose of this invention is to provide a coal discharge mechanism for a shallow trough scraper heavy medium separator, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a coal discharge mechanism for a shallow trough scraper heavy medium separator, comprising: a separator body, a flotation tank inside the separator body, overflow troughs on both outer walls of the flotation tank, a coal discharge port at one end of the flotation tank, and a drive motor on the outside of the separator body; A flow guiding device is provided on the outside of the overflow tank.

[0010] Preferably, mounting blocks are symmetrically arranged on both sides of the scraper, and through holes are opened on the outer surface of the scraper. The number of through holes is set to a plurality and distributed in a rectangular array.

[0011] Preferably, the scraper has an insertion block at its bottom end and a corresponding slot at its top end. The scraper is inserted into the slot via the insertion block, and the mounting block is fixedly connected to the mounting base via bolts.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention features a dual-axis motor mounted on one side of the top of a flow guiding device. Rotating shafts are located at both ends of the motor, and actuating plates are mounted on the outer surface of the rotating shafts. The dual-axis motor drives the actuating plates in overflow troughs on both sides of the rotating shafts to rotate. Several groups of actuating plates are evenly spaced, with each group arranged in a circular array. These actuating plates move the gangue at the bottom of the flotation tank and discharge it from the overflow trough. A guide plate is located on one side of the flow guiding device, through which the gangue discharged from the overflow trough is directed. A strainer is provided on the surface of the guide plate, and a collection box is located at the bottom of the strainer. The suspension carried by the discharged gangue can be guided through the strainer into the collection box for recycling, thus improving resource utilization.

[0013] This invention features a scraper with symmetrical mounting blocks on both sides. The outer surface of the scraper has several through holes arranged in a rectangular array. By adding suspension to the flotation tank, the light coal in the raw coal block is suspended in the upper part of the suspension. The scraper moves the light coal, causing it to be discharged through the coal outlet. The through holes reduce the amount of suspension carried out by the scraper. An insert block is located at the bottom of the scraper, and a corresponding slot is provided at the top of the mounting base. The scraper is quickly positioned and inserted into the slot of the mounting base via the insert block, and then fixed to the mounting base via bolts. This design facilitates quick and easy positioning and installation of the scraper. Attached Figure Description
