Description

Technical Field

[0001] This invention relates to the field of briquetting machine technology, specifically a novel briquetting machine for recycling scrap steel. Background Technology

[0002] A briquetting machine, also known as an iron press, is a commonly used processing equipment in the recycling of scrap steel. It is mainly used to compress loose and irregular scrap steel into briquettes of uniform size, facilitating subsequent transportation and refining. It is mainly used for compressing and forming various materials such as I-beams, thick steel plates, steel pipes, steel scrap, wire mesh, and thin scrap steel. It is widely used in the fields of renewable resource recycling, metallurgy, and steel mills. The equipment has a high degree of automation, strong processing capacity, and produces dense and uniform briquettes, which improves production efficiency and reduces labor costs.

[0003] Currently, existing scrap steel briquetting equipment generates a large amount of rust dust during both feeding and pressing. This dust falls directly into the hydraulic base and cylinder guide parts, easily causing abnormal wear of hydraulic seals, leading to seal failure and oil leakage. This not only pollutes the production site but also shortens the equipment's service life. Summary of the Invention

[0004] The purpose of this invention is to provide a novel briquetting machine for recycling scrap steel, so as to solve the problems mentioned in the background art.

Several identical blowing fans are fixedly installed on the inner wall of the blocking housing. Two negative pressure fans are fixedly installed on the inner wall of the blocking housing. Each negative pressure fan has a processing cylinder fixedly connected inside. Each processing cylinder has an air collecting pipe fixedly connected inside. Each air collecting pipe has a pressure boosting tank fixedly connected inside. The outer surface of each pressure boosting tank is fixedly connected to the inner wall of the blocking housing. Each pressure boosting tank has an air outlet pipe fixedly connected to its inner wall. A moving rod is slidably connected inside each air outlet pipe. The outer surface of each moving rod contacts the inner wall of the blocking housing. A connecting plate is fixedly installed on the outer surface of each moving rod. A baffle is fixedly installed on one side of the two connecting plates that are close to each other. The outer surface of the baffle contacts the inner wall of the blocking housing. The filtration and collection mechanism includes a collection shell, the bottom surface of which is fixedly connected to the inner wall of the barrier shell. The interior of each collection shell is connected to the interior of the processing cylinder. A dual-axis motor is fixedly installed on one side of each processing cylinder. A rotating plate is fixedly installed on one output end of each dual-axis motor. Several identical filter screens are fixedly installed on the bottom surface of each rotating plate. A sealing partition is slidably connected inside each collection shell.

[0006] Preferably, two rotary joints are fixedly installed on the upper surface of the pressure plate, and a hydraulic rod is fixedly installed on the inner wall of each rotary joint.

[0007] Preferably, a material collection seat is provided on the outer side of the pressure plate, a base is fixedly installed on the bottom surface of the material collection seat, and a hydraulic press is fixedly installed on one side of the base.

[0008] Preferably, each of the aggregate shells is slidably connected to a drawer plate inside, and the outer surface of each drawer plate is in contact with the inner wall of the barrier shell.

[0009] Preferably, a sealed bearing is fixedly installed on the inner wall of each of the air outlet pipes, and the interior of each sealed bearing is slidably connected to the outer surface of the moving rod.

[0010] Preferably, each of the air outlet pipes is fixedly connected to a control valve, and each control valve is located inside the barrier housing.

[0011] Preferably, the baffle has two guide plates slidably connected inside, and the bottom surface of each guide plate is fixedly connected to the upper surface of the baffle shell.

[0012] Preferably, a nut is fixedly installed on the inner wall of each of the sealing partitions, a lead screw is threadedly connected to the inner wall of each nut, and a connecting shaft is fixedly installed on the other output end of each of the dual-axis motors.

[0013] Preferably, a synchronous pulley is fixedly installed on the outer surface of each connecting shaft and the outer surface of the lead screw, and a synchronous belt is driven to connect the outer surfaces of every two synchronous pulleys.

[0014] A method for using a new type of briquetting machine for recycling scrap steel includes the following steps: S1: Place the scrap steel into the collection seat, start the hydraulic press to drive the pressure plate to move downwards, and extrude the scrap steel inside the collection seat through the pressure plate. During the extrusion process, the blower continuously delivers airflow into the inner shell of the baffle to blow the dust generated by the extrusion and crushing process to both sides. At the same time, open the control valve to allow the high-pressure gas inside the pressurization tank to be slowly discharged along the air outlet pipe. When the high-pressure gas is discharged, it pushes the moving rod to move downwards along the inner wall of the air outlet pipe, thereby driving the connecting plate and the baffle to move downwards synchronously, sealing and blocking the area of ​​the extrusion operation to prevent dust from spreading outwards. S2: After the air carrying dust enters the treatment cylinder, it is filtered by the filter screen. The dust is intercepted by the filter screen and eventually falls into the collection shell for collection. The filtered clean air is then stored in the pressurization tank through the treatment cylinder and the air collection pipe, and is reserved for the next time to push the baffle to move. S3: After the extrusion operation is completed, the control valve is opened in reverse. The external air pressure drives the moving rod and the baffle to reset upward. Pulling the pull plate can remove the dust and waste collected inside the collection shell. Start the dual-shaft motor. The dual-shaft motor drives the lead screw to rotate through the connecting shaft, synchronous pulley and synchronous belt. The rotation of the lead screw drives the nut and sealing partition to move inward to ensure the sealing of the processing cylinder.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are: First, this invention incorporates a dust-blocking and suction mechanism. The blowing fan can direct the raised dust towards the negative pressure suction direction, thus blocking the spread of dust during the briquetting process and promptly collecting the rust dust generated during the operation. The pressure tank, combined with the moving rod, utilizes the air pressure changes generated by dust suction to automatically adjust the position of the baffle, ensuring overall sealing during briquetting. This prevents dust from scattering and falling into the hydraulic transmission parts of the equipment, effectively reducing wear on hydraulic seals and minimizing oil leakage due to seal failure.

[0016] Secondly, by incorporating a filtration and collection mechanism, this invention can filter and collect dust from the dust-laden airflow drawn into the processing cylinder by the negative pressure fan. The rotating filter screen intercepts and shakes off rust dust in the airflow, and the intercepted dust falls into the collection shell for collection, reducing the dust content in the exhaust airflow and preventing the filtered dust from randomly scattering inside the equipment. This further ensures the service life of the internal structure of the equipment and reduces dust pollution. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 scope of protection of the present invention.

[0020] Example 1

[0021] Please see Figures 1-8 It includes a pressure plate 1, a dust-blocking and suction mechanism 2 is provided on the outside of the pressure plate 1, and a filter collection mechanism 3 is provided on the outside of the pressure plate 1. The dust collection mechanism 2 includes a blocking housing 201. Several identical blowing fans 202 are fixedly installed on the inner wall of the blocking housing 201. Two negative pressure fans 206 are also fixedly installed on the inner wall of the blocking housing 201. Each negative pressure fan 206 has a processing cylinder 213 fixedly connected inside. Each processing cylinder 213 has an air collecting pipe 208 fixedly connected inside. Each air collecting pipe 208 has a pressure boosting tank 205 fixedly connected inside. The outer surface of each pressure boosting tank 205 is fixedly connected to the inner wall of the blocking housing 201. Each pressure boosting tank 205 has an air outlet pipe 211 fixedly connected to its inner wall. A moving rod 207 is slidably connected inside each air outlet pipe 211. The outer surface of each moving rod 207 contacts the inner wall of the blocking housing 201. Connecting plates 204 are fixedly installed on the surface of each device. Baffles 203 are fixedly installed on the side of the two connecting plates 204 that are close to each other. The outer surface of the baffles 203 is in contact with the inner wall of the blocking shell 201. By setting up a dust-collecting mechanism 2, the blowing fan 202 can blow the dust raised in the direction of negative pressure suction, which can block the dust diffusion range during the briquetting operation and can timely extract and collect the rust dust generated during the operation. The structural design of the pressure tank 205 and the moving rod 207 can automatically drive the baffles 203 to adjust their position by utilizing the air pressure change generated by dust suction. The whole device is sealed during briquetting to prevent dust from falling into the hydraulic transmission parts of the equipment after it is scattered everywhere. This effectively reduces the wear of the hydraulic seals by dust and reduces the occurrence of oil leakage due to seal failure.

[0022] Two rotary joints 8 are fixedly installed on the upper surface of the pressure plate 1. A hydraulic rod 5 is fixedly installed on the inner wall of each rotary joint 8. The rotary joints 8 and the hydraulic rod 5 can drive the pressure plate 1 to complete the downward pressing action stably, ensuring that the pressure plate 1 is subjected to uniform and stable force during the pressing process.

[0023] A material collection seat 6 is provided on the outer side of the pressure plate 1. A base 7 is fixedly installed on the bottom surface of the material collection seat 6. A hydraulic press 4 is fixedly installed on one side of the base 7. Through the cooperation of the material collection seat 6 and the hydraulic press 4, a stable power and placement space can be provided for the operation of the pressure plate 1, ensuring the smooth completion of the pressure plate 1 process.

[0024] Each collection shell 301 has a sliding pull plate 302 inside. The outer surface of each pull plate 302 is in contact with the inner wall of the blocking shell 201. The pull plate 302 allows the user to easily pull it out and clean the dust collected inside the collection shell 301, reducing the difficulty of cleaning after dust collection.

[0025] Each air outlet pipe 211 has a sealed bearing 210 fixedly installed on its inner wall. The interior of each sealed bearing 210 is slidably connected to the outer surface of the moving rod 207. The sealed bearing 210 can improve the sealing of the moving rod 207 during movement and prevent leakage of air pressure inside the pressurization tank 205.

[0026] Each vent pipe 211 is fixedly connected to a control valve 212. Each control valve 212 is located inside the blocking housing 201. The control valve 212 can control the air pressure inside the vent pipe 211, so that the baffle 203 can be reset after the pressurization tank 205 exhausts and releases pressure.

[0027] The baffle 203 has two guide plates 209 internally slidably connected. The bottom surface of each guide plate 209 is fixedly connected to the upper surface of the baffle housing 201. The guide plates 209 can guide and limit the movement direction of the baffle 203, ensuring that the movement of the baffle 203 is more stable and smooth.

[0028] The specific implementation method of this embodiment is as follows: When the pressure plate 1 is pressing scrap steel into blocks, the blowing fan 202 and the negative pressure fan 206 are turned on. The blowing fan 202 blows a directional airflow into the pressing area, blowing the rust dust raised during the operation towards the negative pressure fan 206. At the same time, the negative pressure fan 206 generates negative pressure suction, drawing the dust-containing airflow into the pressure tank 205 through the air collection pipe 208. As the air pressure inside the pressure tank 205 continues to rise, the air pressure will push the moving rod 207 to slide outward along the air outlet pipe 211, and then drive the baffle 203 to slide along the guide plate 209 through the connecting plate 204, gradually closing the feed port of the blocking shell 201, so that the pressing area is kept in a relatively closed state, preventing dust from drifting outward and entering the hydraulic parts of the equipment.

[0029] Example 2

[0030] Please see Figures 1-8 The filtration and collection mechanism 3 includes a collection shell 301, the bottom surface of which is fixedly connected to the inner wall of the blocking shell 201. The interior of each collection shell 301 is connected to the interior of the processing cylinder 213. A dual-shaft motor 303 is fixedly installed on one side of each processing cylinder 213. A rotating plate 306 is fixedly installed on one output end of each dual-shaft motor 303. Several identical filter screens 305 are fixedly installed on the bottom surface of each rotating plate 306. A sealing partition 311 is slidably connected inside each collection shell 301. By setting up the filtration and collection mechanism 3, dust-laden airflow drawn into the processing cylinder 213 by the negative pressure fan 206 can be filtered and collected. The rotating filter screens 305 intercept and shake off the rust dust in the airflow. The intercepted dust falls into the collection shell 301 for collection, reducing the dust content in the exhaust airflow and preventing the filtered dust from randomly scattering inside the equipment, further ensuring the service life of the internal structure of the equipment and reducing dust pollution.

[0031] Each sealing partition 311 has a nut 310 fixedly installed on its inner wall, and each nut 310 has a lead screw 309 threadedly connected to its inner wall. Each dual-axis motor 303 has a connecting shaft 304 fixedly installed on its other output end. Through the transmission cooperation of the nut and the lead screw 309, the sealing partition 311 can be driven by the dual-axis motor 303 to move smoothly along the inner wall of the collection shell 301, which facilitates the control of the opening and closing of the collection shell 301.

[0032] Synchronous pulleys 307 are fixedly installed on the outer surface of each connecting shaft 304 and the outer surface of the lead screw 309. A synchronous belt 308 is connected to the outer surface of every two synchronous pulleys 307. Through the transmission of the synchronous pulleys 307 and the synchronous belt 308, the dual-axis motor 303 can drive the rotating plate 306 and the lead screw 309 to move without the need for an additional drive mechanism.

[0033] The specific implementation method of this embodiment is as follows: When the negative pressure fan 206 draws the dusty gas into the treatment cylinder 213, the dual-shaft motor 303 starts. Through the transmission of the connecting shaft 304, synchronous pulley 307, and synchronous belt 308, it drives the rotating plate 306 to rotate on the one hand, and the lead screw 309 to rotate on the other hand. When the lead screw 309 rotates, it drives the sealing partition 311 to move through the nut 310, opening the connection between the collection shell 301 and the treatment cylinder 213. The airflow passes through the rotating filter screen 305 and is discharged from the treatment cylinder 213. The iron in the airflow is removed. Rust dust is trapped by filter screen 305. As filter screen 305 rotates, the dust falls into the collection shell 301 under the action of gravity and is collected. After the briquetting operation is completed, the negative pressure fan 206 stops working. After the air pressure inside the pressure tank 205 stabilizes, the control valve 212 opens to release pressure. The moving rod 207 loses pressure and pushes to reset the baffle 203. At the same time, the dual-shaft motor 303 reverses, driving the sealing baffle 311 to reset and close the collection shell 301, making it convenient for users to clean the dust inside the collection shell 301 by pulling out the pull plate 302.

[0034] A method for using a new type of briquetting machine for recycling scrap steel includes the following steps: S1: Place scrap steel into the collection seat 6, start the hydraulic press 4 to drive the pressure plate 1 to move downward as a whole, and extrude the scrap steel inside the collection seat 6 through the pressure plate 1. During the extrusion process, the blower 202 continuously delivers airflow into the blocking shell 201 to blow the dust generated by the extrusion and crushing process to both sides. At the same time, the control valve 212 is opened to allow the high-pressure gas inside the pressurization tank 205 to be slowly discharged along the air outlet pipe 211. When the high-pressure gas is discharged, it pushes the moving rod 207 to move downward along the inner wall of the air outlet pipe 211, thereby driving the connecting plate 204 and the baffle 203 to move downward synchronously, sealing and blocking the area of ​​the extrusion operation to prevent dust from spreading outward. S2: After the air carrying dust enters the processing cylinder 213, it is filtered by the filter screen 305. The dust is intercepted by the filter screen 305 and finally falls into the collection shell 301 for collection. The filtered clean air is then stored in the pressurization tank 205 through the processing cylinder 213 and the air collection pipe 208, and is reserved for the next time to push the baffle 203 to move. S3: After the extrusion operation is completed, the control valve 212 is opened in reverse. The external air pressure drives the moving rod 207 and the baffle 203 to reset upward. Pulling the pull plate 302 can remove the dust and waste collected inside the collection shell 301. Start the dual-shaft motor 303. The dual-shaft motor 303 drives the lead screw 309 to rotate through the connecting shaft 304, the synchronous pulley 307 and the synchronous belt 308. The rotation of the lead screw 309 drives the nut 310 and the sealing partition 311 to move inward to ensure the sealing of the processing cylinder 213.

[0035] The working principle of this invention is as follows: When the pressure plate 1 is pressing scrap steel into blocks, the blowing fan 202 and the negative pressure fan 206 are turned on. The blowing fan 202 blows a directional airflow into the pressing area, blowing the rust dust raised during the operation towards the negative pressure fan 206. At the same time, the negative pressure fan 206 generates negative pressure suction, drawing the dust-laden airflow into the pressure tank 205 through the air collection pipe 208. As the air pressure inside the pressure tank 205 continues to rise, the air pressure will push the moving rod 207 to slide outward along the air outlet pipe 211, and then drive the baffle 203 to slide along the guide plate 209 through the connecting plate 204, gradually closing the feed inlet of the blocking shell 201, so that the pressing area remains relatively closed, preventing dust from drifting outward and entering the hydraulic parts of the equipment. When the negative pressure fan 206 draws the dust gas into the processing cylinder 213, the dual-shaft motor 303 starts, and through the connecting shaft 304 and the synchronous pulley 3 07. The synchronous belt 308 drives the rotating plate 306 to rotate on one hand and the lead screw 309 to rotate on the other. When the lead screw 309 rotates, it drives the sealing partition 311 to move through the nut 310, opening the connection between the collection shell 301 and the processing cylinder 213. The airflow passes through the rotating filter screen 305 and is discharged from the processing cylinder 213. The rust dust in the airflow is intercepted by the filter screen 305. As the filter screen 305 rotates, the dust falls into the collection shell 301 under the action of gravity and is collected. After the briquetting operation is completed, the negative pressure fan 206 stops working. After the air pressure inside the pressure tank 205 stabilizes, the control valve 212 opens to release pressure. The moving rod 207 loses pressure and pushes to drive the baffle 203 to reset. At the same time, the dual-shaft motor 303 reverses, driving the sealing partition 311 to reset and close the collection shell 301, making it convenient for the user to clean the dust inside the collection shell 301 by pulling out the pull plate 302.
