Description

Technical Field

[0001] This invention belongs to the field of stainless steel bar processing technology, specifically a dust removal and filtration device for stainless steel bar processing. Background Technology

[0002] This stainless steel bar processing fume extraction and filtration device is used to collect and purify the fumes generated during processing. It consists of a dust extraction hood, a piping system, a filter, and a fan. Processing generates large amounts of metallic fumes and gaseous pollutants, which harm the environment, human health, and affect product quality and equipment lifespan. This device collects the fumes through the dust extraction hood, sends them through piping to the filter, where they are purified using high-efficiency filter media or activated carbon. Finally, the fan discharges clean air that meets emission standards.

[0003] A patent with publication number CN117643768B discloses a dust extraction and filtration device for stainless steel bar processing. The device includes a processing table, a dust filter plate slidably connected to one side of the smoke extraction device, and a connecting block fixedly connected to one end of the inner wall of a smoke extraction fan. A drive column is fixedly connected to one side of the outer wall of the connecting block, and multiple fan blades are fixedly connected to the outer wall of the drive column. This dust extraction and filtration device for stainless steel bar processing uses a fixing plate to secure the dust filter plate inside the smoke extraction device. When the dust filter plate needs to be replaced, simply pry open one end of the abutment clip to separate the outer wall of that end from the one-way teeth, allowing the fixing plate to be pulled out. The abutment spring then ejects the dust filter plate through the abutment plate.

[0004] However, in existing stainless steel bar processing fume extraction and filtration devices, after a period of use, the filter plates accumulate a large amount of metal dust due to factors such as static electricity. This dust accumulation severely hinders the normal operation of the subsequent dust collector, resulting in reduced airflow and suction power, and a significant decrease in dust removal quality. To address this issue, existing technologies typically require stopping the entire stainless steel bar processing fume extraction and filtration device and manually replacing the filter plates. However, each filter plate replacement is time-consuming and the disassembly and installation process is cumbersome and complex. Furthermore, during this time, the device cannot perform dust extraction, causing the processing site to be filled with dust, affecting the working environment and worker health, and reducing overall production efficiency.

[0005] Therefore, the present invention provides a dust removal and filtration device for stainless steel bar processing. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this invention to solve its technical problem is as follows: A dust removal and filtration device for stainless steel bar processing, comprising a body, a fixed frame fixedly connected to the upper surface of the body, a stainless steel bar placed above the fixed frame, a positioning frame fixedly connected to the upper surface of the body, an exhaust box fixedly connected inside the positioning frame, a baffle fixedly connected to one side of the positioning frame for dust filtration, a processing component inside the positioning frame, the processing component including a positioning guide rail formed on the inner wall of the positioning frame, a rotating frame slidably connected inside the positioning guide rail, a fixed groove inside the rotating frame, a positioning plate fixedly connected to the middle of the fixed groove, a rotating column rotatably connected to the lower surface of the positioning plate, storage boxes fixedly connected to both sides of the positioning plate for electrostatic spraying the rotating column, several spray holes on the lower surface of the positioning plate, and the rotating column being made of polyurethane roller; an auxiliary component is provided on the lower surface of the rotating frame to assist the rotating column in processing the baffle.

[0008] Preferably, the auxiliary component includes two positioning blocks fixed to the bottom wall of the fixed groove, a rotating plate rotatably connected between the two positioning blocks, and a plurality of protrusions fixed to the upper surface of the rotating plate, each of the protrusions corresponding to a groove on the surface of the baffle.

[0009] Preferably, a connecting spring is fixedly connected to one side of each positioning block, and connecting holes are provided at both ends of the rotating plate. The connecting spring is fixedly connected to the inner wall of the connecting hole. The connecting spring is used for the elastic deformation of the rotating plate to assist the rotating plate in resetting.

[0010] Preferably, the positioning frame is further provided with a cleaning component, which is used to clean metal dust on the circumferential surface of the rotating column. The cleaning component includes an arc-shaped plate that is slidably disposed inside the positioning frame, and the arc-shaped plate can abut against the rotating column.

[0011] Preferably, a first guide rail is fixedly connected to the inner wall of the positioning frame, a first guide block is slidably connected to the lower surface of the first guide rail, an electric push rod is fixedly connected to the bottom end of the first guide block, an auxiliary block is fixedly connected to the output end of the electric push rod, rotating rods are fixedly connected to both sides of the auxiliary block, and arc-shaped plates are rotatably connected to the ends of the two rotating rods.

[0012] Preferably, each of the rotating rods is fixedly connected to a torsion spring at its end, and the torsion spring is fixedly connected to the arc-shaped plate. The torsion spring assists the arc-shaped plate in closely adhering to the circumferential surface of the rotating column for cleaning.

[0013] Preferably, the bottom wall of the positioning frame is further provided with a collection component. The collection component includes auxiliary guide rails fixed to both sides of the inner wall of the positioning frame. An auxiliary groove is opened on one side of the auxiliary guide rail. The same auxiliary plate is slidably connected in the two auxiliary grooves. A collection groove is opened on the upper surface of the auxiliary plate.

[0014] Preferably, when the equipment adsorbs metal dust generated during the processing of stainless steel plates and bars, the positioning guide rail is activated, which drives the rotating frame slidably connected inside. The rotating frame slides along the positioning guide rail. When the rotating frame contacts the baffle, the rotating plate inside the rotating frame rotates. The connecting spring drives the rotating plate to twist until it fully enters the processing range of the baffle. At this time, the protrusion on the upper surface of the rotating plate will insert into the groove between the baffles. At this time, the rotating column on the top wall of the rotating frame abuts against the arc surface of the baffle. The rotating column and the rotating plate will lock the baffle between them. The continued sliding of the rotating frame can drive the rotating column and the protrusion to clean the metal dust from the baffle. During the cleaning process, the storage boxes on both sides of the positioning plate inside the rotating frame are activated. Under the action of the pressure pump, the storage boxes spray out the stored electrostatic spray onto the circumferential surface of the rotating column, making the adsorption capacity of the rotating column stronger and adsorbing the metal dust accumulated on the baffle to its surface.

[0015] Preferably, when the positioning guide rail drives the rotating column to move to the bottom of the baffle, the first guide rail inside the positioning frame is activated. The first guide rail drives the first guide block slidably connected to its lower surface to slide. The first guide block will drive the electric push rod on its lower surface to slide. The electric push rod will drive the auxiliary block fixed to its output end. The auxiliary block will drive the arc-shaped plates fixed to both sides of its sides through rotating rods. In addition, before the first guide rail is activated, the electric push rod is activated to push the arc-shaped plates closer to the rotating column. Since the arc-shaped plates are rotatably connected between the two rotating rods, when the arc-shaped plates abut against the rotating column, the arc-shaped plates will rotate, thereby closely adhering to the rotating column, and the mechanical energy can clean and scrape.

[0016] Preferably, after the arc plate cleans and scrapes the rotating column under the drive of the first guide rail, the scraped metal dust will fall into the auxiliary plate fixed to the bottom wall of the positioning frame under the action of gravity. The auxiliary plate has a collection groove inside for collection. After the auxiliary plate collects a certain amount of metal dust, the auxiliary plate can be pulled out by pulling the pull plate, and then the auxiliary plate can be installed back in its original position for subsequent collection work.

[0017] The beneficial effects of this invention are as follows: 1. The present invention discloses a dust removal and filtration device for stainless steel bar processing. This device has significant advantages in adsorbing and treating metal dust during stainless steel bar processing. First, the device starts by activating the positioning guide rail, driving the rotating frame to slide. After contacting the baffle, the rotating column and rotating plate engage with the baffle. During sliding, the metal dust on the baffle is cleaned. The cooperation between the rotating column and rotating plate covers the entire cleaning range of the baffle, increasing the cleaning area. In addition, during the cleaning process, the storage tank sprays electrostatic spray onto the circumference of the rotating column under the action of a pressure pump, enhancing its adsorption capacity. This allows for more efficient adsorption of the metal dust accumulated on the baffle to the surface. Not only is the cleaning process continuous and efficient, but the enhanced adsorption capacity also improves the dust collection effect, effectively improving the processing environment and reducing dust hazards.

[0018] 2. The stainless steel bar processing dust removal and filtration device of the present invention, by fitting an arc-shaped plate to a rotating column, can comprehensively and efficiently clean and scrape the surface of the rotating column mechanically during subsequent movement, effectively removing the mixture of metal dust and electrostatic spray, ensuring the cleanliness of the rotating column, and improving its subsequent working stability and adsorption efficiency.

[0019] 3. The dust removal and filtration device for stainless steel bar processing described in this invention, after the rotating column is cleaned and scraped by the arc plate, the metal dust falls into the collection groove of the auxiliary plate on the bottom wall of the positioning frame under the action of gravity, realizing the automatic collection of dust, avoiding its scattering and causing secondary pollution, improving the working environment. After the auxiliary plate is full, it can be pulled out by pulling the pull plate, and then reinstalled in its original position to continue collecting. The operation is simple and convenient, effectively improving the efficiency of dust collection and treatment, and ensuring the continuous and stable operation of the equipment.

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] Example 1: As Figures 1 to 9 As shown in the embodiment of the present invention, a dust removal and filtration device for stainless steel bar processing is provided. A fixed frame is fixedly connected to the upper surface of the machine body, and stainless steel bars are placed on top of the fixed frame. A positioning frame is also fixedly connected to the upper surface of the machine body. An exhaust box is fixedly connected inside the positioning frame. A baffle is fixedly connected to one side of the positioning frame for dust filtration. A processing component is provided inside the positioning frame. The processing component includes a positioning guide rail formed on the inner wall of the positioning frame. A rotating frame is slidably connected within the positioning guide rail. A fixed groove is formed inside the rotating frame. A positioning plate is fixedly connected to the center of the fixed groove. A rotating column is rotatably connected to the lower surface of the positioning plate. Storage boxes are fixedly connected to both sides of the positioning plate. The storage box is used for electrostatic spraying of the rotating column. Several spray holes are provided on the lower surface of the positioning plate. The rotating column is made of polyurethane roller. An auxiliary component is provided on the lower surface of the rotating frame to assist the rotating column in processing the baffle. The auxiliary component includes two positioning blocks fixed to the bottom wall of the fixed groove. A rotating plate is rotatably connected between the two positioning blocks. Several protrusions are fixed to the upper surface of the rotating plate, each protrusion corresponding to a groove on the surface of the baffle. A connecting spring is fixed to one side of each positioning block. Connecting holes are provided at both ends of the rotating plate. The connecting spring is fixed to the inner wall of the connecting hole and is used for the elastic deformation of the rotating plate to assist in its resetting.

[0024] Specifically, in the existing stainless steel bar processing fume extraction and filtration devices, after a period of use, a large amount of metal dust will accumulate on the surface of the filter plate due to factors such as static electricity. This dust accumulation will seriously hinder the normal operation of the subsequent dust collector, resulting in reduced air volume and suction power, and a significant reduction in dust removal quality. To address this problem, the existing technology usually requires stopping the entire stainless steel bar processing fume extraction and filtration device and manually replacing the filter plate. However, each replacement of the filter plate is not only time-consuming and complicated from disassembly to installation, but also prevents the device from performing dust extraction during this period, causing the processing site to be filled with fume, affecting the working environment and worker health, and reducing overall production efficiency. Therefore, the present invention solves the above problems by setting the above structure. First, when the equipment adsorbs the metal dust generated during the processing of stainless steel plates and bars, the positioning guide rail is activated. The activation of the positioning guide rail drives the rotating frame that is slidably connected inside. The rotating frame slides along the positioning guide rail. When the rotating frame contacts the baffle, the rotating plate inside the rotating frame rotates. The connecting spring drives the rotating plate to twist until it is fully rotated into the processing range of the baffle. At this time, the protrusion on the upper surface of the rotating plate will insert into the groove between the baffles. At this time, the rotating column on the top wall of the rotating frame abuts against the arc surface of the baffle. The rotating column and the rotating plate will then lock the baffle between them. The continued sliding of the rotating frame can drive the rotating column and the protrusion to clean the metal dust from the baffle. During the cleaning process, the storage boxes on both sides of the positioning plate inside the rotating frame are activated. Under the action of the pressure pump, the storage boxes spray out the electrostatic spray stored inside and spray it onto the circumferential surface of the rotating column, making the adsorption capacity of the rotating column stronger and adsorbing the metal dust accumulated on the baffle to its surface. This equipment offers significant advantages in adsorbing and treating metal dust during the processing of stainless steel plates and bars. Firstly, by activating the positioning guide rail, the rotating frame slides and contacts the baffle. The rotating column and plate engage with the baffle, allowing for efficient cleaning of metal dust during the sliding motion. The cooperation between the rotating column and plate covers the entire cleaning area of ​​the baffle, increasing the cleaning surface. Secondly, during the cleaning process, the storage tank, under the action of a pressure pump, sprays electrostatic mist onto the circumference of the rotating column, enhancing its adsorption capacity. This allows for more efficient adsorption of accumulated metal dust from the baffle to the surface. Not only is the cleaning process continuous and efficient, but the enhanced adsorption capacity also improves dust collection, effectively improving the processing environment and reducing dust hazards.

[0025] Example 2: Figures 1 to 9As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a cleaning component is further provided inside the positioning frame. The cleaning component is used for cleaning metal dust on the circumferential surface of the rotating column. The cleaning component includes an arc-shaped plate slidably disposed inside the positioning frame, which can abut against the rotating column. A first guide rail is fixedly connected to the inner wall of the positioning frame. A first guide block is slidably connected to the lower surface of the first guide rail. An electric push rod is fixedly connected to the bottom end of the first guide block. An auxiliary block is fixedly connected to the output end of the electric push rod. Rotating rods are fixedly connected to both sides of the auxiliary block. Arc-shaped plates are rotatably connected to the ends of the two rotating rods. A torsion spring is fixedly connected to the end of each rotating rod. The torsion spring is fixedly connected to the arc-shaped plate, and the torsion spring assists the arc-shaped plate in closely adhering to the circumferential surface of the rotating column for cleaning.

[0026] Specifically, when the positioning guide rail drives the rotating column to move to the bottom of the baffle, the first guide rail inside the positioning frame is activated. The first guide rail drives the first guide block slidably connected to its lower surface to slide. The first guide block will drive the electric push rod on its lower surface to slide. The electric push rod will drive the auxiliary block fixed to its output end. The auxiliary block will drive the arc-shaped plates fixed to both sides of its sides through the rotating rod. In addition, before the first guide rail is activated, the electric push rod is activated to push the arc-shaped plate closer to the rotating column. Because the arc-shaped plate is rotatably connected between the two rotating rods, when the arc-shaped plate comes into contact with the rotating column, the arc-shaped plate will rotate, thus closely adhering to the rotating column, and the mechanical energy can clean and scrape. By fitting the curved plate into the rotating column, the surface of the rotating column can be mechanically cleaned and scraped thoroughly and efficiently during subsequent movement. This effectively removes the mixture of metal dust and electrostatic spray, ensuring the cleanliness of the rotating column and improving its stability and adsorption efficiency in subsequent operations.

[0027] like Figure 9 As shown, the bottom wall of the positioning frame in this embodiment is also provided with a collection component. The collection component includes auxiliary guide rails fixed to both sides of the inner wall of the positioning frame. An auxiliary groove is opened on one side of the auxiliary guide rail. The same auxiliary plate is slidably connected in the two auxiliary grooves. A collection groove is opened on the upper surface of the auxiliary plate.

[0028] Specifically, after the arc plate cleans and scrapes the rotating column under the drive of the first guide rail, the scraped metal dust will fall into the auxiliary plate fixed to the bottom wall of the positioning frame under the action of gravity. The auxiliary plate has a collection groove inside for collection. After the auxiliary plate collects a certain amount of metal dust, the auxiliary plate can be pulled out by pulling the pull plate, and then the auxiliary plate can be installed back in its original position for subsequent collection work. After the rotating column is cleaned and scraped by the arc-shaped plate, the metal dust falls into the collection groove of the auxiliary plate on the bottom wall of the positioning frame under the action of gravity, realizing the automatic collection of dust, avoiding it from scattering everywhere and causing secondary pollution, and improving the working environment. When the auxiliary plate is full, simply pull the pull plate to remove it for processing, and then reinstall it in its original position to continue collecting. The operation is simple and convenient, effectively improving the efficiency of dust collection and treatment, and ensuring the continuous and stable operation of the equipment.

[0029] Working principle: First, when the equipment adsorbs metal dust generated during the processing of stainless steel plates and bars, the positioning guide rail is activated. The activation of the positioning guide rail drives the rotating frame that is slidably connected inside. The rotating frame slides along the positioning guide rail. When the rotating frame contacts the baffle, the rotating plate inside the rotating frame rotates. The connecting spring drives the rotating plate to twist until it is fully within the processing range of the baffle. At this time, the protrusion on the upper surface of the rotating plate will insert into the groove between the baffles. At this time, the rotating column on the top wall of the rotating frame abuts against the arc surface of the baffle. The rotating column and the rotating plate will lock the baffle between them. The continued sliding of the rotating frame can drive the rotating column and the protrusion to clean the metal dust from the baffle. During the cleaning process, the storage boxes on both sides of the positioning plate inside the rotating frame are activated. Under the action of the pressure pump, the storage boxes spray out the electrostatic spray stored inside, spraying it onto the circumferential surface of the rotating column, making the adsorption capacity of the rotating column stronger and adsorbing the metal dust accumulated on the baffle to its surface.

Furthermore, during the cleaning process, the storage tank, under the action of a pressure pump, sprays electrostatic mist onto the circumference of the rotating column, enhancing its adsorption capacity. This allows for more efficient adsorption of accumulated metal dust from the baffle to the surface. Not only is the cleaning process continuous and efficient, but the enhanced adsorption capacity also improves dust collection, effectively improving the processing environment and reducing dust hazards. Then, when the positioning guide rail drives the rotating column to move to the bottom of the baffle, the first guide rail inside the positioning frame is activated. The first guide rail drives the first guide block slidably connected to its lower surface to slide. The first guide block will drive the electric push rod on its lower surface to slide. The electric push rod will drive the auxiliary block fixed to its output end. The auxiliary block will drive the arc-shaped plates fixed to both sides of its sides through the rotating rod. In addition, before the first guide rail is activated, the electric push rod is activated to push the arc-shaped plate closer to the rotating column. Because the arc-shaped plate is rotatably connected between the two rotating rods, when the arc-shaped plate comes into contact with the rotating column, the arc-shaped plate will rotate, thus closely adhering to the rotating column, and the mechanical energy can clean and scrape. By fitting the arc-shaped plate into the rotating column, the surface of the rotating column can be mechanically cleaned and scraped in a comprehensive and efficient manner during subsequent movement. This effectively removes the mixture of metal dust and electrostatic spray, ensuring the cleanliness of the rotating column and improving its stability and adsorption efficiency in subsequent operations. Finally, after the arc plate cleans and scrapes the rotating column under the drive of the first guide rail, the scraped metal dust will fall into the auxiliary plate fixed to the bottom wall of the positioning frame under the action of gravity. The auxiliary plate has a collection groove inside for collection. After the auxiliary plate collects a certain amount of metal dust, the auxiliary plate can be pulled out by pulling the pull plate, and then the auxiliary plate can be installed back in its original position for subsequent collection work. After the rotating column is cleaned and scraped by the arc-shaped plate, the metal dust falls into the collection groove of the auxiliary plate on the bottom wall of the positioning frame under the action of gravity, realizing the automatic collection of dust, avoiding it from scattering everywhere and causing secondary pollution, and improving the working environment. When the auxiliary plate is full, simply pull the pull plate to remove it for processing, and then reinstall it in its original position to continue collecting. The operation is simple and convenient, effectively improving the efficiency of dust collection and treatment, and ensuring the continuous and stable operation of the equipment.
