Description

Technical Field

[0001] This utility model belongs to the field of workshop dust collection technology, and in particular relates to a negative pressure moving side dust absorption device for workshops. Background Technology

[0002] The negative pressure mobile side-suction dust collection device for workshops is an environmentally friendly device that efficiently collects dust and particulate matter generated during industrial production. Its design combines mobility, side-suction technology, and negative pressure adsorption principle, making it suitable for dust control in workshops such as metallurgy, power, and chemical industries.

[0003] Traditional negative pressure dust collection devices in workshops typically use negative pressure fans to suck in dust and then discharge it directly outdoors. While this method effectively removes dust from the workshop, it can negatively impact the quality of the outside air and cause serious pollution to the surrounding environment over time. This necessitates the use of other methods for environmental remediation, leading to increased subsequent air treatment costs. Utility Model Content

[0004] The purpose of this invention is to provide a negative pressure mobile dust collection device for workshops. By setting up a filter assembly, specifically by activating a negative pressure fan on the workshop wall to generate negative pressure and suck in dust from the workshop, the sucked-in dust first passes through a dust adsorption plate to adsorb dust from the air onto the dust adsorption plate. Then, the filtered air is discharged to the outside through the air outlet. This method can treat dust and significantly reduce dust emissions into the outside air. It solves the problem that traditional workshop negative pressure dust collection devices usually use negative pressure fans to suck in dust and directly discharge it outdoors, but this method will affect the outside air quality and cause serious pollution to the surrounding environment over a long period of time.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a negative pressure mobile side dust collection device for workshops, including a workshop wall, on which two negative pressure fans are installed, and further comprising:

[0007] A dust collection unit is installed on the back of the workshop wall. The dust collection unit is used to filter the intake air and intercept a large amount of dust.

[0008] The dust collection unit is used not only to filter dust, but also to collect dust for subsequent unified dust treatment.

[0009] Furthermore, the dust collection unit includes a dust filter box installed on the back of the workshop wall;

[0010] A vibration assembly is installed on top of a dust filter box and is used to generate vibration.

[0011] A collection component, installed at the bottom of a dust filter box, is used to collect dust;

[0012] A filter assembly, installed inside a dust filter box, is used to filter air drawn into the workshop; and

[0013] A reset assembly, which is installed on the back of the workshop wall, is used to reset the filter assembly;

[0014] The vibration component is used to push the filter component to make the filter component vibrate, and cooperates with the reset component to reset the filter component.

[0015] Furthermore, an air outlet is provided on the back of the dust filter box, a collision plate is fixedly connected to the top of the inner wall of the dust filter box, an opening is provided on the top of the dust filter box, and two sliding grooves are provided on the front of the opening.

[0016] The collision plate is used to collide with the filter assembly, and the air outlet is used to discharge the filtered air.

[0017] Furthermore, the filter assembly includes a dust adsorption plate, a top plate fixedly connected to the top of the dust adsorption plate, limit plates fixedly connected to the left and right sides of the dust adsorption plate, mounting sleeves inserted into the left and right sides of the dust adsorption plate, a rotating shaft fixedly connected to the side of the mounting sleeve away from the dust adsorption plate, the rotating shaft being rotatably connected to the dust filter box, and two pressure rods fixedly connected to the top of the top plate, the two pressure rods being respectively disposed inside two sliding grooves; the dust adsorption plate forms a tortuous path through multiple layers of fiber material (such as HEPA filter), and dust in the airflow is captured by inertial collision, diffusion or interception;

[0018] The dust adsorption plate is inserted into the dust filter box through an opening and is installed by plugging it into two mounting sleeves. The limiting plate limits and supports the dust adsorption plate.

[0019] Furthermore, the vibration assembly includes a housing bolted to the top of the dust filter box, a motor fixedly connected to the right side of the housing, a rotating rod rotatably connected inside the housing, two elliptical blocks fixedly connected to the outer surface of the rotating rod, and the output end of the motor fixedly connected to the rotating rod via a coupling; the elliptical blocks are mounted on the rotating rod by welding.

[0020] The outer surface of the elliptical block is in contact with the surface of the pressure rod, and the housing is detachable, which facilitates the subsequent disassembly of the vibration assembly and thus allows for the smooth installation or removal of the dust adsorption plate.

[0021] Furthermore, the collection assembly includes a placement box fixedly connected to the bottom of the dust filter box, a collection box inserted inside the placement box, and a guide hopper fixedly connected to the bottom of the dust filter box, the guide hopper being funnel-shaped; the placement box and the guide hopper are installed at the bottom of the dust filter box by welding, and the collection box is in the form of a drawer;

[0024] The spherical collision block has its surface in contact with the dust adsorption plate. When the dust adsorption plate is pushed and flipped, it will push the spherical collision block, causing the inner rod to compress the spring. The spring will then store force, which will facilitate the subsequent pushing of the spherical collision block back to its original position and pushing the dust adsorption plate back to its original position so that it collides with the collision plate.

[0025] This utility model has the following beneficial effects:

[0026] 1. This utility model uses a filter assembly, specifically by activating a negative pressure fan on the workshop wall to generate negative pressure and draw in dust from the workshop. The dust drawn in then passes through a dust adsorption plate, which adsorbs the dust in the air onto the dust adsorption plate.

[0027] 2. This utility model incorporates a vibration component. Specifically, a motor drives a rotating rod to rotate, causing the elliptical block to rotate as well. As the elliptical block rotates, it pushes the pressure rod, causing the dust adsorption plate to oscillate continuously and collide with the collision plate.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0039] Please see Figures 1-6As shown, this utility model is a negative pressure mobile side dust absorption device for workshops, including a workshop wall 1, two negative pressure fans 11 installed on the workshop wall 1, and also including:

[0040] Dust collection unit 2 is installed on the back of the workshop wall 1. Dust collection unit 2 is used to filter the intake air and intercept a large amount of dust.

[0041] The dust collection unit 2 is used not only to filter dust, but also to collect dust for subsequent unified dust treatment.

[0042] The dust collection unit 2 includes a dust filter box 21 installed on the back of the workshop wall 1;

[0043] Vibration assembly 22 is installed on top of dust filter box 21 and is used to generate vibration.

[0044] Collection component 23 is installed at the bottom of dust filter box 21 and is used to collect dust;

[0045] Filter assembly 24, installed inside dust filter box 21, is used to filter air drawn into the workshop; and

[0046] Reset assembly 25 is installed on the back of workshop wall 1 and is used to reset filter assembly 24.

[0047] The vibration component 22 is used to push the filter component 24 to make the filter component 24 vibrate, and cooperate with the reset component 25 to reset the filter component 24.

[0048] The dust filter box 21 has an air outlet 211 on the back, a collision plate 212 is fixedly connected to the top of the inner wall of the dust filter box 21, and an opening 213 is opened on the top of the dust filter box 21. Two sliding grooves 214 are opened on the front of the opening 213.

[0049] The collision plate 212 is used to collide with the filter assembly 24, and the air outlet 211 is used to discharge the filtered air.

[0050] The filter assembly 24 includes a dust adsorption plate 241, a top plate 242 fixedly connected to the top of the dust adsorption plate 241, limit plates 243 fixedly connected to the left and right sides of the dust adsorption plate 241, and mounting sleeves 244 inserted into the left and right sides of the dust adsorption plate 241. A rotating shaft 245 is fixedly connected to the side of the mounting sleeve 244 away from the dust adsorption plate 241, and the rotating shaft 245 is rotatably connected to the dust filter box 21. Two pressure rods 246 are fixedly connected to the top of the top plate 242, and the two pressure rods 246 are respectively set inside two sliding grooves 214. By setting the filter assembly 24, specifically by starting the negative pressure fan 11 on the workshop wall 1, negative pressure is generated to draw in the dust in the workshop. The dust drawn in will first pass through the dust adsorption plate 241, adsorbing the dust in the air onto the dust adsorption plate 241. Then, the filtered air is discharged to the outside from the air outlet 211. This method can treat the dust and greatly reduce the dust emitted into the outside air.

[0051] The dust adsorption plate 241 is inserted into the dust filter box 21 through the opening 213 and is installed by plugging it into the two mounting sleeves 244. The limiting plate 243 limits and supports the dust adsorption plate 241.

[0052] The vibration assembly 22 includes a housing 221 bolted to the top of the dust filter box 21. A motor 222 is fixedly connected to the right side of the housing 221. A rotating rod 223 is rotatably connected inside the housing 221. Two elliptical blocks 224 are fixedly connected to the outer surface of the rotating rod 223. The output end of the motor 222 is fixedly connected to the rotating rod 223 via a coupling. When the motor 222 is started, it drives the rotating rod 223 to rotate, and the elliptical blocks 224 rotate along with it. When the elliptical blocks 224 rotate, they push the pressure rod 246, causing the dust adsorption plate 241 to swing continuously and collide with the collision plate 212. This repetition causes the dust adsorption plate 241 to vibrate continuously, dislodging the attached dust and collecting it in the collection box 232. This method can improve the service life of the dust adsorption plate 241 and reduce clogging.

[0053] The outer surface of the elliptical block 224 is in contact with the surface of the pressure rod 246, and the housing 221 is detachable, which facilitates the subsequent disassembly of the vibration assembly 22 as a whole, thereby allowing the dust adsorption plate 241 to be installed or removed smoothly.

[0054] The collection component 23 includes a placement box 231 fixedly connected to the bottom of the dust filter box 21, a collection box 232 inserted inside the placement box 231, and a guide hopper 233 fixedly connected to the bottom of the dust filter box 21. The guide hopper 233 is funnel-shaped.

[0055] The guide bucket 233 is used to guide the falling dust so that it can smoothly enter the collection box 232 for collection.

[0056] The reset assembly 25 includes an outer rod 251 fixedly connected to the back of the workshop wall 1, an inner rod 252 slidably connected inside the outer rod 251, a spherical collision block 253 fixedly connected to the back of the inner rod 252, and a spring 254 provided inside the outer rod 251. The back of the spring 254 is fixedly connected to the front of the inner rod 252, and the front of the spring 254 is fixedly connected to the inner wall of the outer rod 251.

[0057] The spherical collision block 253 is in contact with the surface of the dust adsorption plate 241. When the dust adsorption plate 241 is pushed and flipped, it will push the spherical collision block 253, causing the inner rod 252 to squeeze the spring 254. The spring 254 will then store force, which will facilitate the subsequent push of the spherical collision block 253 to reset and push the dust adsorption plate 241 to reset and collide with the collision plate 212.

[0058] One specific application of this embodiment is:

[0059] In use, by starting the negative pressure fan 11 on the workshop wall 1, negative pressure is generated to suck in the dust in the workshop. The sucked-in dust will first pass through the dust adsorption plate 241, which adsorbs the dust in the air onto the dust adsorption plate 241. The dust adsorption plate 241 forms a tortuous path through multiple layers of fiber materials (such as HEPA filter). The dust in the airflow is captured by inertial collision, diffusion or interception. Then the filtered air is discharged to the outside from the air outlet 211. This method can treat the dust and greatly reduce the dust emitted into the outside air. When a lot of dust is attached to the dust adsorption plate 241, it will fall off and enter the collection box 232 through the guide bucket 233 for collection, which is convenient for subsequent unified dust treatment.

[0060] When cleaning the dust adsorption plate 241 is required, first stop the negative pressure fan 11, then start the motor 222 to drive the rotating rod 223 to rotate. The elliptical block 224 will then rotate along with it. When the elliptical block 224 rotates, it will push the pressure rod 246. The pressure rod 246 will then push the top of the dust adsorption plate 241 forward. Since the dust adsorption plate 241 rotates on the dust filter box 21 via the rotating shaft 245 on the mounting sleeve 244, the dust adsorption plate 241 can be pushed smoothly. When the dust adsorption plate 241 moves, it will contact the spherical collision block 253 and push the spherical collision block 253, causing the inner rod 25 to... 2. The inner rod 252 slides inside the outer rod 251 and compresses the spring 254. When the protrusion on the elliptical block 224 leaves the pressure rod 246, the inner rod 252 returns to its original position under the elastic action of the spring 254. At this time, the spherical collision block 253 pushes the dust adsorption plate 241 back to its original position, and the dust adsorption plate 241 collides with the collision plate 212, thereby causing the dust adsorption plate 241 to vibrate. This process is repeated so that the dust adsorption plate 241 can continuously vibrate, causing the attached dust to fall off and be collected in the collection box 232. This method can improve the service life of the dust adsorption plate 241 and reduce clogging.

[0061] Furthermore, by disassembling the entire housing 221 and then pulling the pressure rod 246 to move the dust adsorption plate 241 upward to disassemble it, the dust adsorption plate 241 is detached from the mounting sleeve 244, making it convenient for subsequent replacement or maintenance of the dust adsorption plate 241. When it is necessary to install the dust adsorption plate 241, the dust adsorption plate 241 is inserted into the two mounting sleeves 244, and the limiting plate 243 is in contact with the top of the mounting sleeve 244 to limit and support the dust adsorption plate 241. At this time, the pressure rod 246 enters the slide groove 214 to complete the installation of the dust adsorption plate 241, and then the housing 221 can be installed.
