Description

Technical Field

[0001] This invention relates to the field of processing and reusing recycled glass raw materials, and in particular to an iron removal device for recycled glass raw materials. Background Technology

[0002] As older buildings age and are demolished, the market for recycling and reusing waste glass is growing. Glass recycling from construction waste often contains small amounts of iron impurities, which significantly impact the recycling process. Currently, methods for removing iron impurities from waste glass include manual methods, which can easily injure workers and are inefficient; and iron removal machines—such as those with patents CN201720492224.8 and CN202022523343.X—which rely solely on magnets, resulting in low efficiency and some iron filings easily getting stuck in the glass and unable to be removed by the magnets. Therefore, how to safely and effectively remove iron impurities has become a crucial step in the glass waste recycling industry. Summary of the Invention

[0003] In view of the problems of low safety and insufficient iron removal in existing methods for removing iron from glass raw materials, this invention discloses a device that can safely and effectively remove iron impurities from recycled glass raw materials.

[0004] A glass recycling raw material iron removal device includes an iron removal operating tank, a drain pipe, an iron removal stirring head, an iron filings adsorption rod, a liquid storage connection device, a connecting rod, a lifting rod, a rotating disk, and a control unit. The bottom of the iron removal operating tank has a drain port, and a first solenoid valve is installed at the drain port. The first solenoid valve is electrically connected to the control unit. One end of the drain pipe is fitted into the drain port. The iron removal stirring head is a petal-shaped device with a central shaft hole, which is fixedly connected to one end of the iron filings adsorption rod. The iron filings adsorption rod is made of magnetically conductive metal, with through holes at both ends, and one end of the iron filings adsorption rod is rotatably connected to the bottom of the liquid storage connection device. The liquid storage connection device internally includes a liquid storage chamber, an electromagnetic generator, and a first servo motor. The liquid storage chamber contains iron removal liquid. The outer wall of the liquid storage chamber has an inlet and an outlet. The outlet is fitted into a through-hole at one end of the iron filings adsorption rod. A second electromagnetic valve is installed at the outlet and is electrically connected to the control host. The electromagnetic generator is in contact with the iron filings adsorption rod and provides magnetic conductivity. The output end of the first servo motor is fixedly connected to the iron filings adsorption rod. The side of the liquid storage connection device is fixedly connected to one end of a connecting rod. A lifting body is installed at the top of the lifting rod, and the lifting body is slidably connected to the lifting rod. The end of the connecting rod away from the liquid storage connection device is fixedly connected to the lifting body. A second servo motor is installed inside the lifting body. The outer wall of the lifting rod has a row of toothed grooves. The output end of the second servo motor meshes with the toothed grooves through a transmission device. The bottom end of the lifting rod is fixedly connected to a rotating disk. The rotating disk is mounted on the top of the control host. A third servo motor is installed inside the rotating disk. The top of the control host has toothed grooves, and the output end of the third servo motor meshes with the toothed grooves. The control host includes a control body, a touch screen, a power button, a first servo driver, a second servo driver, a third servo driver, an electromagnetic driver, and a digital signal processor. The electromagnetic generator is electrically connected to the electromagnetic driver. The first servo driver is electrically connected to the first servo motor, the second servo driver is electrically connected to the second servo motor, and the third servo driver is electrically connected to the third servo motor. The first solenoid valve, the second solenoid valve, the electromagnetic driver, the first servo driver, the second servo driver, the third servo driver, the touch screen, and the power button are all electrically connected to the digital signal processor.

[0005] This invention utilizes an iron-removing stirring blade to break down the glass recycling raw material, making it easier for the iron filings to be adsorbed after the iron filings adsorption rod is magnetically connected. Simultaneously, in the next process, the iron-removing liquid from the storage connection device is injected into the iron-removing operating tank through the iron filings adsorption rod, dissolving and removing any remaining unadsorbed iron filings. This significantly improves the removal efficiency of iron impurities from the glass recycling raw material.

[0006] Furthermore, the material of the iron filings adsorption rod is low-carbon steel with a carbon content of 0.01% to 0.04%.

[0007] Low-carbon steel has high magnetic permeability, as well as high material strength and toughness, making it less likely to be damaged during the process of mixing and crushing raw materials with the cutter head.

[0008] Furthermore, the iron removal device for glass recycling raw materials also includes an iron filings adsorption support rod. One end of the iron filings adsorption support rod is provided with a thread, and the side of the iron filings adsorption rod is provided with a threaded hole. The iron filings adsorption support rod is fixedly connected to the iron filings adsorption rod through the threaded hole.

[0009] The iron filings adsorption support rod increases the contact opportunity between the magnetic structure and the raw material to be processed, thus improving operating efficiency. In addition, the iron filings adsorption support rod is easy to disassemble and can be replaced independently after damage, reducing maintenance costs.

[0010] Furthermore, the inner wall of the iron filings adsorption rod is coated with a polyvinyl chloride coating.

[0011] The polyvinyl chloride coating can effectively prevent corrosion from the iron removal liquid and extend the service life of the iron filings adsorption rod.

[0012] Furthermore, the material of the iron filings adsorption support rod is an iron-silicon alloy with a silicon content of 1% to 4.8%; or an iron-nickel alloy with a nickel content of 50% to 90%; or an iron-nickel alloy with a nickel content of 50% to 90%.

[0013] Iron filings adsorption rods do not require load-bearing capacity and are easy to replace. Other magnetically conductive materials can be used, allowing for a flexible balance between factors such as magnetic conductivity, durability, and cost, depending on the actual application scenario.

[0014] Furthermore, the molten iron is composed of a hydrochloric acid solution with a concentration of 30% to 60%.

[0015] Hydrochloric acid solution can effectively dissolve iron impurities and iron oxides, and it is inexpensive and readily available.

[0016] Beneficial effects:

[0017] This invention integrates two iron removal methods: magnetic adsorption and chemical reagent removal. It can safely and effectively remove iron impurities from recycled glass raw materials, with a high degree of automation and high efficiency in removing iron impurities. Attached Figure Description

The iron removal stirring head 3 is a petal-shaped device with a shaft hole at its center, and the shaft hole of the iron removal stirring head 3 is fixedly connected to one end of the iron filings adsorption rod 4. The iron filings adsorption rod 4 is made of magnetically conductive metal, with through holes at both ends and an internal through-hole. One end of the iron filings adsorption rod 4 is rotatably connected to the bottom end of the liquid storage connection device 6. The liquid storage connection device 6 is equipped with a liquid storage chamber, an electromagnetic generator, and a first servo motor. The liquid storage chamber stores iron removal liquid. The outer wall of the liquid storage chamber is provided with an inlet 7 and an outlet. The outlet is fitted and connected to one end of the iron filings adsorption rod 4. The outlet is equipped with a second electromagnetic valve, which is electrically connected to the control host. The electromagnetic generator is in contact with the iron filings adsorption rod 4 and conducts magnetic flux. The output end of the first servo motor is fixedly connected to the iron filings adsorption rod 4. The side of the liquid storage connection device 6 is fixedly connected to one end of the connecting rod 8. A lifting body 10 is provided at the top of the lifting rod 9. The lifting body 10 is slidably connected to the lifting rod 9. The end of the connecting rod 8 away from the liquid storage connecting device 6 is fixedly connected to the lifting body 10. A second servo motor is provided inside the lifting body 10. A toothed longitudinal row 11 is provided on the outer wall of the lifting rod 9. The output end of the second servo motor meshes with the toothed longitudinal row 11 through a transmission device. The bottom end of the lifting rod 9 is fixedly connected to the rotating disk 12. The rotating disk 12 is installed on the top of the control host. A third servo motor is provided inside the rotating disk 12. A toothed groove is provided on the top of the control host.

[0022] In the iron removal operation of recycled glass raw materials, the present invention first injects the raw materials into the iron removal operation tank 1. The control host operates the rotating disk 12 to rotate, placing the iron removal stirring head 3 directly above the iron removal operation tank 1. Then, the control host controls the lifting body 10 to descend, while the iron removal stirring head 3 starts rotating at high speed to break up the raw materials, causing some of the iron debris attached to the glass to detach from the glass. After the raw materials are broken up, the control host operates the iron removal stirring head 3 to stir at low speed, while the electromagnetic generator is activated. The iron filings adsorption rod 4 and the iron filings adsorption support rod 5 are magnetically connected, starting to adsorb iron filings. After completing one working cycle of adsorption, the lifting body 10 rises, the rotating disk 12 rotates, and the electromagnetic generator stops working when it reaches the designated position, and the iron filings fall off. Several magnetic adsorption operations are repeated until no more iron filings are obviously adsorbed. The control unit moves the iron filings adsorption rod 4 directly above the iron removal operating tank 1 again. The lifting body 10 does not descend, the second solenoid valve opens, and the iron removal liquid flows into the iron removal operating tank 1 through the iron filings adsorption rod 4, immersing the raw material. After a certain period of time, the first solenoid valve opens, discharging the waste liquid. At this point, the iron impurities in the glass recycling raw material have been completely removed, and the glass recycling raw material can be taken out for the next step of processing.

[0023] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
