Description

Technical Field

[0001] This utility model relates to the field of coal slag treatment technology, and in particular to a coal slag treatment device with magnetic separation function. Background Technology

[0002] Coal, as an important global energy source and industrial raw material, produces a large amount of slag when burned in fields such as thermal power generation, metallurgy, chemical industry, and heating.

[0003] In the prior art, such as Chinese Patent No. CN216322596U, a media recovery device for a magnetic separator used in coal preparation is disclosed. This device includes a base plate and a first conveyor belt. The first conveyor belt is installed horizontally at one end of the top of the base plate, and a third conveyor belt is also horizontally installed on the top of the base plate, directly below the first conveyor belt. A second conveyor belt is horizontally installed at the other end of the top of the base plate, with one end of the second conveyor belt attached to the top of one end of the first conveyor belt. A cleaning mechanism for cleaning the first conveyor belt is provided at the bottom of the first conveyor belt, and first circular rollers are provided at both ends inside the first conveyor belt. Magnetic rollers and second circular rollers are respectively provided at both ends inside the second conveyor belt, and a rotating mechanism for rotating the magnetic rollers is provided on the side of the first conveyor belt. A magnetic plate is installed horizontally on one side inside the second conveyor belt. This patent avoids excessive adhesion affecting magnetic separation, thereby improving the device's performance.

[0004] In the above technical solution, the coal slag to be magnetically separated is placed on the first conveyor belt for conveying, and then adsorbed and magnetically separated by magnetic rollers and magnetic plates on the second conveyor. However, the material placed on the first conveyor belt may accumulate during conveying, which may cause the material to be adsorbed in the coal slag at the bottom to be affected by insufficient magnetic force during adsorption and magnetic separation, thus affecting the magnetic separation effect.

[0005] Based on this, a coal slag treatment device with magnetic separation function is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a coal slag treatment device with magnetic separation function to solve the problems mentioned in the background art.

[0007] The technical solution of this utility model is: a coal slag treatment device with magnetic separation function, including a base plate, the upper surface of which has multiple through holes, and the inner walls of the multiple through holes are fixedly connected to support legs, and also includes:

[0008] The workbench has multiple mounting holes on its upper surface. Two of the mounting holes have sliding rods slidably connected to their inner walls, and two other mounting holes have sealing cylinders fixedly connected to their inner walls. Two sealing cylinders have piston rods slidably connected to their inner walls. The top ends of the two piston rods and the two sliding rods are fixedly connected to the same bottom frame. The surfaces of the sealing cylinders are respectively fixedly connected to an air intake pipe and an air outlet pipe. One-way valves are fixedly installed on the surfaces of the air intake pipe and the air outlet pipe.

[0009] A rotating rod has multiple cams fixedly connected to its surface, and multiple rollers are fixedly installed on the lower surface of the base frame, with each roller corresponding to one of the multiple cams.

[0010] In some embodiments, spring one and spring two are respectively fitted onto the surfaces of the two slide rods and the two piston rods, and the two ends of spring one and spring two are respectively fixedly connected to the opposite surfaces of the bottom frame and the worktable.

[0011] In some embodiments, a motor is fixedly connected to the upper surface of the workbench via a mounting bracket, and the output end of the motor is fixedly connected to one end of a rotating rod.

[0012] In some embodiments, a scraper is fixedly connected to the lower surface of the bottom frame, the air outlets of the two air outlet pipes are located on one side of the scraper, and a conveyor belt is provided on the inner wall of the bottom frame.

[0013] In some embodiments, a rectangular groove is formed on the upper surface of the workbench, a material discharge port is fixedly connected to the inner wall of the rectangular groove, a magnetic separation transmission device is fixedly connected to the upper surface of the workbench, and a collection box is provided on the upper surface of the base plate.

[0014] Compared with existing technologies, the significant advantages of this invention are:

[0015] Firstly, this invention uses a motor to start the rotating rod and its cam. The cam periodically pushes the rollers on the lower surface of the bottom frame, causing the bottom frame to reciprocate up and down along the sliding rod and piston rod, thereby vibrating and dispersing the material to prevent coal slag from accumulating. When the coal slag is transported to the bottom of the magnetic separation transmission device, it will be attracted by the magnetic separation transmission device.

[0016] Secondly, the scraper of this utility model is located at the bottom of the base frame, which can scrape the conveyor belt to avoid excessive coal slag adhering to the conveyor belt and affecting the magnetic separation effect. When the base frame vibrates back and forth, the piston rod moves back and forth in the sealed cylinder, drawing in air through the air intake pipe and then spraying air out through the air outlet pipe to blow air onto the coal slag scraped off the scraper, thus preventing coal slag from adhering to the scraper and affecting the scraping effect.

Detailed Implementation

[0024] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0025] This utility model provides an improved coal slag treatment device with magnetic separation function. The technical solution of this utility model is as follows:

[0026] like Figures 1-4 As shown, a coal slag treatment device with magnetic separation function includes a base plate 1. The base plate 1 is generally made of carbon steel or wear-resistant steel plate, which has sufficient strength and corrosion resistance, and serves as the basic support structure for the entire device to ensure the stability of the device during operation. Multiple through holes are opened on the upper surface of the base plate 1, and support legs 2 are fixedly connected to the inner walls of each through hole. The device also includes:

[0027] The workbench 4 and the base frame 6 can be made of welded steel with rust-proof treatment. The workbench 4 is used to install various functional components, and the base frame 6 is used to support the conveyor belt 7 and scraper 8, and to disperse materials under the action of the vibration mechanism. The elastic vibration of the base frame 6 is achieved through the cooperation of the slide rod 15 and the spring 16 to prevent coal slag from caking. The upper surface of the workbench 4 has multiple mounting holes, two of which are slidably connected to the inner wall of the slide rod 15, and the inner wall of the other two mounting holes is fixedly connected to the sealing cylinder 17. The sealing cylinder 17 can... Made of stainless steel, the piston rod 18 is a chrome-plated steel rod, and the air pipe is a pressure-resistant rubber tube. The piston rod 18 is slidably connected to the inner wall of the two sealing cylinders 17. The top ends of the two piston rods 18 and the two sliding rods 15 are fixedly connected to the same bottom frame 6. The surface of the sealing cylinders 17 is respectively fixedly connected to the suction pipe 20 and the exhaust pipe 14. The piston rod 18 reciprocates in the sealing cylinder 17, generating airflow, which is blown to the scraper 8 area through the exhaust pipe 14 to assist in cleaning and separation. One-way valves 21 are fixedly installed on the surface of the suction pipe 20 and the exhaust pipe 14.

[0028] The rotating rod 10 has multiple cams 12 fixedly connected to its surface. The cams 12 and rollers 9 can be hardened to improve wear resistance. The motor 11 drives the rotating rod 10 to rotate, and the cams 12 push the rollers 9, causing the bottom frame 6 to move up and down, achieving periodic vibration. This effectively disperses the coal slag pile and improves magnetic separation efficiency and adsorption rate. Multiple rollers 9 are fixedly installed on the lower surface of the bottom frame 6, and each roller 9 corresponds to a different cam 12.

[0029] like Figure 3 and Figure 4 As shown, in one embodiment, the surfaces of the two slide rods 15 and the two piston rods 18 are respectively fitted with spring one 16 and spring two 19, and the two ends of the two spring one 16 and spring two 19 are fixedly connected to the opposite surfaces of the bottom frame 6 and the worktable 4, respectively.

[0030] A motor 11 is fixedly connected to the upper surface of the workbench 4 via a mounting bracket, and the output end of the motor 11 is fixedly connected to one end of the rotating rod 10.

[0031] A scraper 8 is fixedly connected to the lower surface of the bottom frame 6, and the air outlets of the two air outlet pipes 14 are located on one side of the scraper 8. A conveyor belt 7 is provided on the inner wall of the bottom frame 6.

[0032] like Figure 2As shown, in one embodiment, a rectangular groove is provided on the upper surface of the workbench 4, and a material discharge port 13 is fixedly connected to the inner wall of the rectangular groove. A magnetic separation transmission device 5 is fixedly connected to the upper surface of the workbench 4. The conveyor belt 7 is a rubber belt with built-in magnetic material, and the magnetic separation roller is made of strong magnetic neodymium iron boron material. The magnetic separation transmission device 5 is responsible for adsorbing ferromagnetic substances, and the conveyor belt 7 is responsible for conveying non-magnetic materials to the material discharge port 13, so as to achieve efficient separation of iron and non-iron substances in the slag and facilitate subsequent recycling. A collection box 3 is provided on the upper surface of the bottom plate 1.

[0033] The specific working method is as follows: During use, coal slag is transported by conveyor belt 7. After motor 11 is started, it drives rotating rod 10 and cam 12 on it to rotate. Cam 12 periodically pushes roller 9 on the lower surface of bottom frame 6, causing bottom frame 6 to move up and down along slide rod 15 and piston rod 18, realizing vibration and dispersion of material, preventing coal slag from accumulating. When coal slag is transported to the magnetic separation transmission device 5, it will be attracted by magnetic separation transmission device 5.

[0034] Meanwhile, the scraper 8, located at the bottom of the base frame 6, scrapes the conveyor belt 7, preventing excessive coal slag from adhering to it and affecting the magnetic separation effect. As the base frame 6 vibrates reciprocally, the piston rod 18 reciprocates within the sealed cylinder 17, drawing in air through the suction pipe 20 and then expelling it through the exhaust pipe 14 to blow air onto the scraper 8, preventing coal slag from adhering to it and affecting the scraping effect. The magnetic roller in the magnetic separation transmission device 5 adsorbs ferromagnetic substances from the coal slag, while non-magnetic materials fall into the collection box 3 through the discharge port 13, completing the separation and collection.

[0035] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
