Description

Technical Field

[0001] This utility model relates to the field of metal recycling equipment, and in particular to an integrated machine for pressing and drying iron scrap briquettes. Background Technology

[0002] During machining processes, metal cutting and grinding generate a large amount of iron filings, which are usually mixed with coolant. The presence of coolant not only increases the weight and volume of the iron filings but also may cause environmental pollution and resource waste. Therefore, when recycling iron filings, it is necessary to first remove the mixed coolant and compact the iron filings to improve transportation efficiency and subsequent smelting value.

[0003] Existing iron scrap recycling equipment mainly achieves compaction of iron scrap through a pressing process. Specifically, loose iron scrap is fed into a briquetting machine mold, where high pressure is applied vertically using hydraulic or mechanical pressure, causing the scrap to interlock and expel the coolant from the internal gaps, ultimately forming a dense iron cake. This type of equipment can significantly reduce the volume of iron scrap, facilitating storage and transportation. Simultaneously, the extrusion process removes some of the coolant, providing a pretreatment basis for subsequent drying or smelting.

[0004] However, existing briquetting equipment has significant drawbacks in actual operation: during the high-pressure pressing process, the discharged coolant splashes outwards due to pressure, causing some coolant to re-adhere to the surface of the iron briquettes or seep into the gaps at the edges. This "secondary absorption" phenomenon not only reduces the coolant recovery rate but also affects the subsequent drying efficiency due to residual moisture on the surface of the iron briquettes, prolonging the drying time and increasing energy consumption. Furthermore, the splashed coolant may pollute the environment around the equipment, increasing cleaning costs and becoming a technical bottleneck restricting the efficiency and environmental friendliness of iron scrap recycling. Utility Model Content

[0005] To overcome the drawbacks of secondary absorption, this utility model provides an integrated iron scrap briquetting and drying machine, which aims to solve the above-mentioned shortcomings.

[0006] A metal scrap briquetting and drying integrated machine includes a briquetting machine and a drying chamber. The briquetting machine has a discharge port on its right end and is equipped with a controller. The drying chamber is located to the right of the briquetting machine and is connected to a drying box. A conveyor belt is installed in the middle of the drying box, and the left end of the conveyor belt is connected to the discharge port. A water storage chamber is located at the bottom of the drying chamber, and a heating plate is installed at the bottom of the drying chamber. Several water supply pipes are connected to the rear side. The bottom end of each water supply pipe passes through the drying chamber and is equipped with a water pump. The water pump is wired to the controller. The top of each water supply pipe passes through the top plate of the drying chamber and is connected to a drain pipe. The bottom of the drain pipe has an opening, and the drain pipe is located at the top of the drying box.

[0007] As an improvement to the above solution, an exhaust pipe is connected to the top of the drying chamber, a top cover is provided on the top of the exhaust pipe, and an installation plate is connected to the top of the exhaust pipe. The rotating shaft of the top cover is rotatably connected to the installation plate. A torsion spring is sleeved on the rotating shaft of the top cover. One end of the torsion spring is connected to the installation plate, and the other end is connected to the top cover.

[0008] As an improvement to the above solution, a sealing gasket is provided on the top surface of the exhaust pipe, and the sealing gasket is pressed together with the top cover.

[0009] As an improvement to the above solution, an extension plate is connected to the right end of the discharge port, and the extension plate is in contact with the conveyor belt.

[0010] As an improvement to the above solution, a guide plate is connected to the bottom of the drying chamber, and the guide plate is provided with an inclined surface facing the water pump.

[0011] As an improvement to the above solution, curtains are provided at both the left and right ends of the drying chamber.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The hot water circulation system formed by the heating plate and the water storage chamber ensures that the iron cake is heated evenly during the conveying process, evaporates the coolant, avoids liquid residue that may lead to secondary absorption, and improves drying efficiency and iron cake quality.

[0014] 2. The sloping design at the top of the drain pipe guides the hot water to flow evenly into the water storage chamber, forming a circulating heating path. This ensures that the coolant on the surface and inside the iron cake evaporates fully, reducing residue, preventing secondary absorption, and improving drying uniformity.

[0015] 3. Through the automatic opening and closing of the top cover and exhaust pipe, the pressure balance inside the drying chamber is maintained by the torsion spring reset and the elastic deformation of the sealing gasket, reducing water vapor loss, keeping the temperature inside the chamber stable, promoting the complete evaporation of coolant, and avoiding secondary absorption.

[0022] Example: An integrated machine for pressing and drying iron scrap briquettes, such as Figures 1-4 As shown, the assembly includes a briquetting machine 1, a discharge port 2, a controller 3, a drying chamber 4, a conveyor belt 5, a drying box 6, a water storage chamber 7, a heating plate 8, a water pump 9, a water supply pipe 10, and a drain pipe 11. The briquetting machine 1 has a discharge port 2 at its right end. The controller 3 is installed on the briquetting machine 1. The drying chamber 4 is located to the right of the briquetting machine 1. A drying box 6 is connected inside the drying chamber 4. A conveyor belt 5 is installed in the middle of the drying box 6, and its left end connects to the discharge port 2. A water storage chamber 7 is located at the bottom of the drying chamber 4. A heating plate 8 is installed at the bottom of the drying chamber 4. The heating plate 8 and the drying chamber 4 are connected to several water pipes 10. The temperature control setting threshold of the heating plate 8 is 80-120℃ to achieve uniform heating and avoid overheating. The bottom end of the water pipe 10 passes through the drying chamber 4 and is equipped with a water pump 9. The water pump 9 is wired to the controller 3. The top of the water pipe 10 passes through the top plate of the drying chamber 4 and is connected to a drain pipe 11. The bottom of the drain pipe 11 is provided with an opening. The drain pipe 11 is located at the top of the drying box 6. The top of the drying box 6 is provided with a slope in the left and right directions.

[0023] like Figure 1 and Figure 3 As shown, it also includes an exhaust pipe 12, a top cover 13, a mounting plate 14, and a torsion spring 15. The top of the drying chamber 4 is connected to the exhaust pipe 12, the top of the exhaust pipe 12 is provided with a top cover 13, the top of the exhaust pipe 12 is connected to the mounting plate 14, the rotating shaft of the top cover 13 is rotatably connected to the mounting plate 14, and the rotating shaft of the top cover 13 is fitted with a torsion spring 15. One end of the torsion spring 15 is connected to the mounting plate 14, and the other end is connected to the top cover 13.

[0024] like Figure 3 As shown, it also includes a sealing gasket 16. The top surface of the exhaust pipe 12 is provided with a sealing gasket 16. The sealing gasket 16 is pressed and fitted with the top cover 13. The sealing gasket 16 is made of high temperature resistant silicone material to ensure sealing and durability.

[0025] like Figure 4 As shown, it also includes an extension plate 17. The right end of the discharge port 2 is connected to the extension plate 17, and the extension plate 17 is in contact with the conveyor belt 5.

[0026] like Figure 2 As shown, it also includes a guide plate 18. The bottom of the drying chamber 4 is connected to the guide plate 18. The guide plate 18 is provided with an inclined surface facing the water pump 9. The guide plate 18 is made of corrosion-resistant metal.

[0027] like Figure 1 As shown, it also includes a door curtain 19, with door curtains 19 installed at both the left and right ends of the drying chamber 4.

[0028] The operator starts the briquetting machine 1 and conveyor belt 5 via controller 3. Iron filings are vertically compressed into iron cakes within the briquetting machine 1 and then pushed to the right from the discharge port 2. The extension plate 17 extending from the right end of the discharge port 2 contacts the surface of the conveyor belt 5, ensuring a smooth transition of the iron cake onto the conveyor belt 5 and preventing it from slipping or shifting due to inertia. The conveyor belt 5 continues to transport the iron cake to the right, sending it into the drying area within the drying chamber 4.

[0029] After the heating plate 8 is powered on, it heats the water in the water storage chamber 7. Simultaneously, the water pump 9 starts to draw hot water from the bottom of the drying chamber 4. The hot water is transported to the drain pipe 11 through the water supply pipe 10. From the bottom opening of the drain pipe 11, it flows along the inclined surface of the top of the drying box 6 to the two side water storage chambers 7, maintaining a stable water temperature in the water storage chambers 7. The iron cakes on the conveyor belt 5 are heated inside the drying box 6, and the surface and internal coolant evaporate due to the heat, achieving the effect of drying while conveying. The dried iron cakes continue to move with the conveyor belt 5 until they leave the drying box 6.

[0030] The heating plate 8 continuously generates water vapor, causing the air pressure inside the drying chamber 4 to gradually increase. When the air pressure exceeds the set torque of the torsion spring 15, the top cover 13 is pushed by the air pressure to rotate around the pivot, and the torsion spring 15 is twisted and deformed accordingly. The exhaust pipe 12 opens to release some water vapor. After the air pressure decreases, the torsion spring 15 returns to its original position, causing the top cover 13 to rotate in the opposite direction. When the top cover 13 and the top of the exhaust pipe 12 close, they compress the sealing gasket 16. The sealing gasket 16 buffers the impact force through elastic deformation, ensuring that the drying chamber 4 returns to its closed state and reducing heat loss.

[0031] When the position of the discharge port 2 is adjusted, the extension plate 17 adjusts its extension length simultaneously to always maintain stable contact between the iron cake and the conveyor belt 5; the guide plate 18 at the bottom of the water storage chamber 7 guides the water flow to the suction port of the water pump 9, ensuring that the water pump 9 can effectively pump water even if the water volume decreases; the curtains 19 at both ends of the drying chamber 4 sway slightly with the movement of the conveyor belt 5 to form a dynamic sealing barrier, effectively preventing water vapor from escaping from both sides, maintaining a stable temperature inside the drying chamber 4, and improving drying efficiency.

[0032] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Therefore, all equivalent changes made based on the content described in the claims of the present utility model should be included within the scope of the claims of the present utility model.
