Description

Technical Field

[0001] This utility model relates to the technical field of scrap steel recycling and processing equipment, and in particular to a scrap steel crushing material impurity blowing and separation device. Background Technology

[0002] In scrap steel recycling workshops, scrap steel collected from various locations undergoes crushing, sorting, and other processes to be processed into relatively small particles such as smeltable scrap steel and scrap iron, which are then transported to relevant smelters for smelting. During this process, after initial crushing and screening, the scrap steel is transported to other locations for further processing or packaged and sent to smelters. However, even after this processing, the scrap steel slag still contains a large number of impurities, including dust, waste paper, and waste plastic. If the crushed scrap steel is transported out for smelting in this way, the subsequent smelting and impurity removal process will become more complicated, affecting the quality and efficiency of scrap steel smelting and recycling. Utility Model Content

[0003] The purpose of this invention is to provide a blower separation device for impurities in scrap steel crushed material, which addresses the above-mentioned situation. This blower separation device has a simple structural design and obvious practical effect.

[0004] The specific solution of this utility model is as follows: a scrap steel crushing material impurity blowing and separation device, including a first belt conveyor and a second belt conveyor. The first belt conveyor is arranged horizontally, and the second belt conveyor is arranged obliquely by an inclined support frame. The lower end of the second belt conveyor is connected to the lower part of the first belt conveyor. A receiving hopper is provided directly below the high end outlet of the second belt conveyor. The discharge port of the receiving hopper is arranged obliquely outward. An ash silo is provided on one side of the back of the receiving hopper. An ash inlet is provided at the upper end of the ash silo, which is arranged obliquely towards the high end outlet of the second belt conveyor. An ash outlet is provided at the lower end of the ash silo. Blowing brackets are also provided on the inclined support frames on both sides of the high end outlet of the second belt conveyor. Support screws are installed on the blowing brackets, and three blowers are installed side by side on the support screws. The three blowers blow air simultaneously towards the ash inlet at the upper end of the ash silo.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," etc., indicating orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are only for the convenience of describing this utility model or simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed or operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0022] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] See Figures 1 to 7This utility model relates to a waste steel crushing material impurity blowing and separation device, comprising a first belt conveyor 1 and a second belt conveyor 2. The first belt conveyor is horizontally arranged, and the second belt conveyor is obliquely arranged and supported by an inclined support frame 3. The lower end of the second belt conveyor is connected to the lower part of the first belt conveyor. Furthermore, in this utility model, both the first and second belt conveyors are wide belt conveyors. The mixed material is conveyed from the first belt conveyor to the second belt conveyor. A receiving hopper 7 is provided directly below the high end outlet of the second belt conveyor, and the discharge port of the receiving hopper is obliquely arranged outward. Furthermore, the receiving hopper in this utility model is an open vertical hopper, and its inner wall is located at the high end outlet of the second belt conveyor. The ash hopper is designed with a sloping structure at its bottom. A ash silo 4 is located on one side of the back of the receiving hopper. An ash inlet 10 is located at the upper end of the ash silo, angled towards the high-end outlet of the second belt conveyor. An ash outlet 11 is located at the lower end of the ash silo. Furthermore, the ash silo in this invention has a vertical structure. The inner wall of the ash silo is sloping relative to the ash inlet, which is located at a position slopingly below the high-end outlet of the second belt conveyor. Air blower brackets 5 extend outward from the sloping support frames on both sides of the high-end outlet of the second belt conveyor. Support screws 9 are mounted on the air blower brackets, and three air blowers 6 are mounted side-by-side on the support screws, blowing air simultaneously towards the ash inlet at the upper end of the ash silo.

[0024] Furthermore, in this utility model, the housings of all three hair dryers are mounted on the supporting screws, and the housings of each hair dryer are locked and fixed on both sides by locking nuts 8; the housing of the hair dryer is a cylindrical structure with open ends, a hair dryer motor is mounted on the housing of the hair dryer, and a hair dryer blade is installed inside the housing of the hair dryer. The output shaft of the hair dryer motor is connected to the hair dryer blade through a through hole opened on the supporting screw.

[0025] The first belt conveyor 1 and the second belt conveyor 2 in this utility model are ordinary long and wide belt conveyors. Their function is to transfer and collect the crushed scrap steel for other uses. When the scrap steel reaches the upper outlet of the inclined second belt conveyor, the crushed material, mixed with various paper scraps, plastic scraps, and other debris, will fall vertically downwards into the receiving hopper directly below due to its own gravity. At the same time, three blowers are turned on simultaneously. As the material falls, the debris, being much lighter, is easily blown obliquely into the ash and slag bin for collection. See [link to relevant documentation]. Figure 1 As shown, the heavier metal shavings will automatically fall into the receiving hopper, thus separating the two.

[0026] The tilt angle of the hair dryer in this invention can be adjusted as needed to achieve the best blowing angle and blowing effect. This adjustment can be made by tightening the lock nut.

[0027] In this invention, the ash silo is designed at an angle below the upper outlet of the second belt conveyor to achieve the best ash silo collection effect; the receiving hopper in this invention adopts an open and angled design, so that the scrap steel slag can be easily collected and slid down into it.

[0028] This invention utilizes multiple blowers at the high-end outlet of the second belt conveyor to promptly blow away and collect lighter dust and impurities from the conveyed scrap steel chips, allowing the scrap steel chips and impurities to naturally separate outside the outlet, thus achieving the purpose of cleaning the scrap steel chips. Furthermore, by incorporating an ash and slag silo and a receiving hopper at the top outlet of the second belt conveyor, this invention enables real-time separate collection of ash and scrap steel, significantly improving production efficiency. The three blowers in this invention have adjustable blowing angles, effectively adapting to on-site requirements and achieving efficient separation.
