Description

Technical Field

[0001] This utility model relates to the field of industrial dust removal equipment technology, specifically to an intelligent smoke and dust tracking and control device. Background Technology

[0002] The mechanical crushing and high-temperature melting of scrap steel by cutting equipment (such as oxy-acetylene cutting and plasma cutting) causes metal oxidation, generating a large amount of iron oxide dust with a particle size mostly less than 10 micrometers (inhalable particulate matter). This dust is further compounded by the thermal decomposition of impurities such as oil, rust, and paint adhering to the scrap steel surface, forming a complex dust. The large amounts of dust and toxic gases generated during the operation not only pose a threat to workers' occupational health but also increase the risk of environmental pollution. Due to the diverse sources of scrap steel, its size and the amount of pollution generated vary considerably. Therefore, the treatment of pollutants from scrap steel cutting is characterized by unpredictable pollution sources and large fluctuations in pollutant concentrations, making treatment extremely difficult. Currently, the main dust control technologies include spray dust suppression technology (e.g., 201922415132.1), mobile small-scale purification devices, and mobile dust collection chamber technology (e.g., CN201721733059.7).

[0003] Current dust control technologies and their shortcomings: 1. Spray dust suppression technology (representative patent: a mobile open-air scrap steel cutting fume suppressor, 201922415132.1). This technology uses a spray device to spray water mist while cutting. The dust and water mist combine and settle to the ground to achieve the purpose of dust suppression. In essence, this technology does not recover pollutants. The pollutants that settle to the ground are very likely to cause secondary pollution after drying, and it also has a certain impact on the normal work of the workers.

[0004] 2. Mobile small-scale purification device technology generally uses miniaturized cartridge dust collectors. These cartridge dust collectors are movable and equipped with a movable exhaust hood. During operation, the exhaust hood is moved above the pollution source, and the pollutants are drawn into the dust collector for purification using the principle of local negative pressure suction. This device is easy to move and is very effective when the exhaust hood is above the pollution source and the amount of pollutants is small. However, due to the small size of the exhaust hood, the effect is not ideal for cutting larger scrap steel or when the amount of pollutants is large. Furthermore, the limited capacity of the cartridges can easily cause clogging when handling high concentrations of dust, thus affecting operational efficiency.

[0005] 3. Mobile dust collection chamber technology (such as automatic sealed mobile dust hood, CN201721733059.7). This technology consists of a mobile dust collection hood and an electric anti-theft roller shutter door. During operation, the dust collection chamber is moved to the location of the scrap steel to be cut, placing it inside the dust collection chamber. During operation, the lifting door is lowered to form a sealed hood, and pollutants are collected and treated through the exhaust hood at the top. This technology has advantages such as mobility, high sealing performance, and large processing capacity. However, in actual use, this type of device cannot regulate the airflow organization within the dust collection chamber, resulting in a chimney effect that contaminates the breathing zone of the operators.

[0006] In summary, there is an urgent need for an intelligent smoke and dust tracking and control device to solve or at least partially solve the problems existing in the prior art. Utility Model Content

[0007] The purpose of this utility model is to provide an intelligent smoke and dust tracking and control device, which aims to solve the technical problem that existing dust removal equipment pollutes the breathing zone of operators, preventing them from breathing fresh air. The specific technical solution is as follows: An intelligent smoke and dust tracking and control device includes a dust collector hood and an entrance / exit door installed on the dust collector hood. The entrance / exit door is installed on the side wall of the dust collector hood. The dust collector hood is provided with an air inlet and an air outlet. The air inlet is arranged on the side of the dust collector hood adjacent to the entrance / exit door, and the air outlet is arranged on the top of the dust collector hood. It also includes an air inlet louver regulating valve, which is installed at the air inlet on the dust collector hood to adjust the size of the air inlet and the airflow direction of the air inlet.

[0008] Multiple air inlets are arranged, distributed on the side walls adjacent to the entrance and exit gates. Multiple air inlet louver regulating valves are also provided, each mounted on the side wall of the dust collector hood, with each valve corresponding to one of the air inlets. Multiple air outlet louver regulating valves are also included, laid flat inside the dust collector hood, separating a working chamber and a collecting chamber within the hood. The collecting chamber is located above the working chamber, and the air outlet louver regulating valves connect the working chamber and the collecting chamber. The air inlets are connected to the working chamber, and the air outlets are connected to the collecting chamber.

[0009] Preferably, the cross-section of the dust collector hood is arranged in a rectangular shape.

[0010] Preferably, four inlet louver regulating valves and four outlet louver regulating valves are arranged, with two inlet louver regulating valves arranged on the side of the dust collector hood adjacent to the inlet and outlet, and the other two inlet louver regulating valves arranged on the other side adjacent to the inlet and outlet; the four outlet louver regulating valves are arranged in a grid pattern on the top of the dust collector hood.

[0011] Preferably, it also includes an exhaust mechanism, which is arranged on the top of the dust collector hood and is connected to the top of the dust collector hood.

[0012] Preferably, it also includes an oxygen pipe electric mechanism, with two oxygen pipe electric mechanisms arranged at two opposite corners of the dust collector hood; both the inlet louver regulating valve and the outlet louver regulating valve are electric louver regulating valves; the oxygen pipe electric mechanism is electrically connected to the inlet louver regulating valve closest to itself and to the outlet louver regulating valve furthest from itself.

[0013] Preferably, it also includes a lighting mechanism and a top frame, the top frame being fixedly connected to the top of the dust collector hood, and the exhaust louver regulating valve being installed on the top frame; the lighting mechanism is installed at the lower end of the top frame.

[0014] Preferably, the upper end of the dust collector hood is arranged to taper inward.

[0015] Preferably, it also includes a dust concentration detection mechanism, which is arranged inside the working chamber to detect the dust concentration in the working chamber; the exhaust mechanism is electrically connected to four dust concentration detection mechanisms at the same time.

[0016] Preferably, it also includes a walking mechanism, which is arranged at the bottom of the dust collector hood; the walking mechanism includes multiple walking wheels, which are fixedly connected to the bottom of the dust collector hood.

[0017] Preferably, the walking mechanism further includes a track, on which the walking wheels are arranged to roll. Two doors are provided for the entrance and exit, which are arranged opposite each other on two side walls of the dust hood. The two doors are arranged along the length of the track so that the operator and the items to be cut can enter the dust hood along the track.

[0018] The application of the technical solution of this utility model has the following beneficial effects: When scrap steel needs to be cut, the scrap steel is moved from the inlet / outlet into the dust hood. During the cutting process, the air intake louver regulating valve adjusts the direction of air intake, so that the airflow flows towards the breathing zone of the cutting operator. This ensures that the cutting operator can always breathe fresh air during the cutting operation, preventing the air in the breathing zone from being contaminated and causing the cutting operator to inhale polluted gases, which could threaten the operator's life and property safety.

[0019] During operation, when air enters through the intake louver regulating valve near the operator, the air flows towards the operator and then towards the exhaust louver regulating valve on the opposite side. The air then enters the collection chamber and is finally discharged from the outlet. In other words, fresh air flows from the side closest to the operator towards the side furthest away. Meanwhile, the fumes generated during cutting are located on the side furthest from the operator. These fumes flow upwards from this side towards the open exhaust louver regulating valve, enter the collection chamber, and are finally discharged from the outlet. Because the open exhaust louver regulating valve is located on the side furthest from the operator, and the open intake louver regulating valve is located on the side closest to the operator, fresh air flows from the side closest to the operator towards the side furthest away. This prevents contaminated air from flowing from the side furthest from the operator towards the operator, thus preventing fumes from contaminating the operator's breathing zone.

[0023] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be provided below, along with preferred embodiments. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to enable a more thorough and complete understanding of the disclosure of this utility model.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0025] Example: See Figures 1-5 This embodiment provides an intelligent smoke and dust tracking and control device, including a dust hood 1 and an entrance / exit 2 installed on the dust hood 1. The entrance / exit 2 is installed on the side wall of the dust hood 1. The dust hood 1 is provided with an air inlet 11 and an air outlet 12. The air inlet 11 is arranged on the side of the dust hood 1 adjacent to the entrance / exit 2, and the air outlet 12 is arranged on the top of the dust hood 1. It also includes an air inlet louver regulating valve 3, which is installed at the air inlet 11 on the dust hood 1 to adjust the size of the air inlet 11 and the airflow direction of the air inlet 11. Specifically, the height of the air inlet louver regulating valve 3 is approximately equivalent to the waist level of a human, so that when the fresh air entering from the air inlet louver regulating valve 3 flows towards the operator, it can flow towards the operator's mouth and nose (breathing zone), preventing smoke and dust from contaminating the operator's breathing zone, so that the operator always breathes clean, fresh air with low smoke and dust content, thereby protecting the operator.

[0026] During operation, the dust hood 1 is placed on the ground. When scrap steel needs to be cut, it is moved into the dust hood 1 through the inlet / outlet 2. During the cutting process, the air intake louver regulating valve 3 adjusts the direction of air intake, directing the airflow towards the operator's breathing zone. This ensures that the operator always breathes fresh air during the cutting operation, preventing contamination of the breathing zone and thus avoiding the inhalation of polluted air that could threaten the operator's life and property. Through this structural design, the airflow direction is changed, directing fresh air towards the operator, ensuring a constant supply of fresh air in the operator's breathing zone and preventing the inhalation of contaminated air that could endanger their safety.

[0027] Research revealed that while the aforementioned structure allows fresh air to flow towards the operator, during the cutting process, the polluted air generated may drift towards the operator's side as it rises, potentially contaminating the operator's breathing zone. Based on this, the following further improvements were made.

[0028] Multiple air inlets 11 are arranged, and the multiple air inlets 11 are distributed on the side walls of the two sides adjacent to the entrance and exit gate 2. Multiple air inlet louver regulating valves 3 are provided, and the multiple air inlet louver regulating valves 3 are all installed on the side wall of the dust collector hood 1, and the multiple air inlet louver regulating valves 3 are arranged in a one-to-one correspondence with the air inlets 11. It also includes multiple air outlet louver regulating valves 4, and the multiple air outlet louver regulating valves 4 are arranged flat inside the dust collector hood 1. The air outlet louver regulating valves 4 separate the working chamber 13 and the air collection chamber 14 inside the dust collector hood 1. The air collection chamber 14 is located above the working chamber 13. The air outlet louver regulating valves 4 are used to connect the working chamber 13 and the air collection chamber 14. The air inlets 11 are connected to the working chamber 13, and the air outlets 12 are connected to the air collection chamber 14.

[0029] It can be understood that by arranging multiple air inlets 11 and multiple air inlet louver regulating valves 3, during operation, the air inlet louver regulating valve 3 near the operator and the air outlet louver regulating valve 4 away from the operator are opened, while the air inlet louver regulating valves 3 and air outlet louver regulating valves 4 in other positions are kept closed. With this configuration, during operation, when air enters through the air inlet louver regulating valve 3 (closer to the operator), it flows towards the operator and then towards the air outlet louver regulating valve 4 (farther from the operator), entering the air collection chamber 14 and finally exiting through the air outlet 12. In other words, fresh air flows from the side closer to the operator towards the side farther away. Meanwhile, the smoke and dust generated during cutting are located on the side farther from the operator. This smoke and dust flows upwards from the side farther from the operator towards the open air outlet louver regulating valve 4, enters the air collection chamber 14, and finally exits through the air outlet 12. Because the open air outlet louver regulating valve 4 is located on the side farther from the operator, while the open air inlet louver regulating valve 3 is located on the side closer to the operator, fresh air from the outside flows from the side closer to the operator towards the side farther away. This prevents contaminated air from flowing from the side farther from the operator towards the operator, thus preventing smoke and dust from contaminating the operator's breathing zone.

[0030] In this embodiment, the cross-section of the dust hood 1 is arranged in a rectangle. It is understood that by setting it to a rectangle, it is convenient for processing and for installing other accessories on the rectangular dust hood 1. Of course, in some other embodiments of this application, the cross-section of the dust hood 1 along the horizontal direction can also be arranged in a circular, regular polygonal, elliptical, or other irregular shapes.

[0031] Preferably, four air inlet louver regulating valves 3 and four air outlet louver regulating valves 4 are arranged, with two air inlet louver regulating valves 3 arranged on the side of the dust collector hood 1 adjacent to the door 2, and the other two air inlet louver regulating valves 3 arranged on the other side adjacent to the door 2; the four air outlet louver regulating valves 4 are arranged in a grid pattern on the top of the dust collector hood 1.

[0032] When the dust collector hood 1 is in operation, the two air inlet louver regulating valves 3 on one side are opened, and the air outlet louver regulating valve 4 on the side away from the air inlet louver regulating valve 3 is opened. At this time, the fresh air entering from the outside air inlet louver regulating valve 3 flows through the working chamber 13 to the air outlet louver regulating valve 4, so that a fresh air flow channel is formed in the working chamber 13, preventing the smoke and dust generated during cutting from flowing backward.

[0033] It should be noted that in some embodiments of this application, both the intake louver regulating valve 3 and the exhaust louver regulating valve 4 are electric louver regulating valves.

[0034] Specifically, the electric louvered regulating valve includes a mounting frame 31, a drive motor 32, a transmission mechanism 33, blades 34, and a rotating shaft 35. Multiple rotating shafts 35 and blades 34 are arranged, with the shafts 35 evenly spaced along the height of the mounting frame 31 and rotatably connected to it. The shafts 35 are parallel to each other. Each blade 34 corresponds to one of the rotating shafts 35 and is fixedly connected to it. The blades 34 are parallel to each other, forming an air inlet duct 36 between adjacent blades 34. Rotation of the rotating shafts 35 drives the blades 34 to rotate, thereby adjusting the size and direction of the air duct. The drive motor 32 is mounted on the mounting frame 31 and drives all rotating shafts 35 to rotate simultaneously and be positioned via the transmission mechanism 33.

[0035] Specifically, the mounting frame 31 is a rectangular frame. The transmission mechanism 33 includes multiple sets of synchronous pulleys 331 and synchronous belts 332. Each set includes one synchronous belt 332 and two synchronous pulleys 331. One set is arranged between every two adjacent rotating shafts 35. One synchronous pulley 331 is coaxially and fixedly connected to one of the rotating shafts 35, and the other synchronous pulley 331 is coaxially and fixedly connected to the other rotating shaft 35. The synchronous belt 332 is wound around the two synchronous pulleys 331. The drive motor 32 is mounted on the rectangular frame, and the output shaft of the drive motor 32 is coaxially and fixedly connected to one of the rotating shafts 35 to drive the rotating shaft 35 to rotate. When the rotating shaft 35 rotates, it drives the other rotating shafts 35 to rotate through the cooperation of the synchronous pulleys 331 and the synchronous belt 332.

[0036] Preferably, the system also includes an oxygen pipe electric mechanism 6, with two oxygen pipe electric mechanisms 6 arranged at opposite corners of the dust collector hood 1. Both the inlet louver regulating valve 3 and the outlet louver regulating valve 4 are electrically operated. Each oxygen pipe electric mechanism 6 is electrically connected to the inlet louver regulating valve 3 closest to it and to the outlet louver regulating valve 4 furthest from it. Specifically, the oxygen pipe electric mechanism 6 is an oxygen solenoid valve. When one of the oxygen solenoid valves is open, the inlet louver regulating valve 3 closest to it opens, while the one furthest from it closes. Similarly, the outlet louver regulating valve 4 furthest from it opens, and the one closest to it closes. It should be noted that the oxygen pipe electric mechanism 6 only controls the opening and closing of the inlet louver regulating valve 3 and the outlet louver regulating valve 4 during startup. In subsequent construction work, the dust concentration detection mechanism 5 controls the opening degree of the inlet louver regulating valve 3 and the outlet louver regulating valve 4. Of course, the opening of the air intake louver regulating valve 3 and the air outlet louver regulating valve 4 can also be controlled by a program or adjusted manually in subsequent construction work.

[0037] It should be noted that the system also includes an acetylene valve 103. During the cutting operation, oxygen and acetylene are required. Oxygen is connected to the dust hood 1 through an oxygen pipe, and acetylene is connected to the dust hood 1 through an acetylene pipe. An oxygen pipe electric mechanism 6 is installed on the oxygen pipe to control the flow of oxygen. An acetylene valve 103 is installed on the acetylene pipe to control the flow of acetylene.

[0038] Preferably, the system also includes a lighting mechanism 7 and a top frame 8. The top frame 8 is fixedly connected inside the dust collector hood 1, and the exhaust louver regulating valve 4 is mounted on the top frame 8. The lighting mechanism 7 is mounted at the lower end of the top frame 8. The top frame 8 securely and firmly mounts the exhaust louver regulating valve 4. The lighting mechanism 7 illuminates the inside of the dust collector hood 1, increasing its brightness to facilitate cutting operations. The lighting mechanism 7 is one of an incandescent lamp, an LED lamp, or a fluorescent lamp.

[0039] Preferably, the upper end of the dust hood 1 is arranged to taper inward.

[0040] It is known that the constricted arrangement facilitates the collection of smoke and dust, and also facilitates connection with the subsequent exhaust mechanism 9.

[0041] Preferably, it also includes an exhaust mechanism 9, which is arranged on the top of the dust removal hood 1 and is connected to the top of the dust removal hood 1.

[0042] It is understood that by setting up the exhaust mechanism 9, air is drawn from the air collection chamber 14, thereby creating a negative pressure within the air collection chamber 14. This negative pressure causes the smoke and dust in the working chamber 13 to quickly enter the air collection chamber 14 through the exhaust louver regulating valve 4 and be discharged from the exhaust port 12 and the exhaust mechanism 9, thus improving the smoke and dust emission efficiency and preventing smoke and dust accumulation in the working chamber. The exhaust mechanism 9 includes an exhaust pipe, a filter, and an exhaust fan. The exhaust pipe connects to the exhaust port 12 of the dust collector hood 1. The first end of the filter is connected to the end of the exhaust pipe furthest from the dust collector hood 1, and the second end of the filter is connected to the exhaust fan.

[0043] Preferably, the system also includes a dust concentration detection mechanism 5, which is arranged inside the working chamber 13 to detect the dust concentration in the working chamber 13. Four dust concentration detection mechanisms 5 are arranged, each corresponding to one of the four exhaust louver regulating valves 4, located on the air inlet side of the exhaust louver regulating valves 4. The air inlet louver regulating valves 4 are electrically operated. The exhaust mechanism 9 is electrically connected to all four dust concentration detection mechanisms 5. Specifically, the dust concentration detection mechanism 5 is a TSP (Total Particulate Spectrometer) sensor. Alternatively, the dust concentration detection mechanism 5 can also be identified by an identification sensor or other sensors capable of detecting dust concentration, for detecting the dust concentration during cutting.

[0044] By electrically connecting the dust concentration detection mechanism 5 and the exhaust mechanism 9, when the dust concentration detection mechanism 5 detects a low dust concentration, it controls the exhaust mechanism 9 to reduce its power, thereby saving energy while still meeting the exhaust requirements. When the dust concentration detection mechanism 5 detects a high dust concentration, it controls the exhaust mechanism 9 to increase its power, enabling the dust to be quickly discharged for better dust removal.

[0045] It can be seen that by setting up four dust concentration detection mechanisms 5 to detect the dust concentration at four locations, and by combining the dust concentration data from the four dust concentration detection mechanisms 5, the required exhaust power can be determined, thereby more accurately controlling the power of the exhaust mechanism 9, and achieving energy saving while meeting the usage requirements.

[0046] Preferably, the system further includes a traveling mechanism 10, which is arranged at the bottom of the dust collector hood 1. The traveling mechanism 10 includes multiple traveling wheels 101, which are fixedly connected to the bottom of the dust collector hood 1. The traveling mechanism 10 facilitates the movement of the dust collector hood 1.

[0047] Specifically, the walking mechanism 10 also includes a track 102, with the walking wheels 101 rolling on the track 102. Two doors 2 are provided, which are arranged opposite to each other on the two side walls of the dust hood 1. The two doors 2 are arranged along the length of the track 102 so that the operator and the items to be cut can enter the dust hood 1 along the direction of the track 102.

[0048] When cutting is required, place the object between the two tracks 102, open the two access doors 2, and push the dust hood 1 towards the object. The traveling wheels 101 roll along the tracks 102, causing the dust hood 1 to move along the tracks 102 until it completely covers the object. Then close the access doors 2 to begin cutting. The traveling mechanism 10 facilitates the movement of the dust hood 1, making construction easier. It should be noted that during construction, the access doors 2 can be partially opened to increase the amount of fresh air entering.

[0049] It should be noted that entrance door 2 is a roller shutter door, which can be either an electric roller shutter door or a manual roller shutter door.

[0050] It also includes a machine vision detection mechanism 104, which is installed inside the dust hood 1. It can be installed on the mounting frame 31 or on the inner wall of the dust hood 1. The machine vision detection mechanism 104 identifies the position of the operator and controls the air intake louver regulating valve 3 close to the operator to open and the air intake louver regulating valve 3 far from the operator to close in real time during the cutting operation. The air exhaust louver regulating valve 4 far from the operator is opened and the air exhaust louver regulating valve 4 close to the operator is closed. This ensures that during the cutting operation, no matter where the operator moves inside the dust hood 1, fresh air from the outside will always flow to the operator's breathing zone first, improving the safety of the operator's cutting operation.

[0051] The specific work process is as follows: Place the material to be cut between the two tracks 102, open the inlet / outlet 2 on the dust hood 1 near the material, and push the dust hood 1 to completely cover the material to be cut. Close the inlet / outlet 2 and turn on the lighting mechanism 7. When the operator turns on the cutting flame gun, the oxygen pipe electric mechanism 6 and the acetylene valve 103 open simultaneously. When the oxygen pipe electric mechanism 6 opens, it controls the ventilation mechanism 9, the air inlet louver regulating valve 3 near the operator, and the air outlet louver regulating valve 4 away from the operator to open. The smoke and dust generated during the cutting process enter the gas collection chamber 14 through the working chamber 13 via the air outlet louver regulating valve 4, and are finally discharged from the outlet 12 through the exhaust mechanism. Fresh air enters through the air inlet duct 36 of the air inlet louver regulating valve 3 near the operator and is blown towards the operator's breathing zone, finally flowing to the air outlet louver regulating valve 4. During operation, the dust concentration in the dust collector hood 1 is detected by the dust concentration detection mechanism 5. The exhaust mechanism 9 adjusts its output power value according to the real-time data detected by the TSP, so that the power of the exhaust mechanism 9 is reduced while meeting the dust removal requirements, thereby saving energy and avoiding the situation of over-powering the machine. When the dust concentration is high, the power of the exhaust mechanism 9 increases while the door 2 is partially opened to provide supplementary air and ensure sufficient fresh air intake. When the operator moves inside the dust hood 1, the machine vision detection mechanism 104 detects the operator's position and adjusts the angle of the blades 34 in the air intake louver regulating valve 3 that is close to the operator, so that the air intake duct 36 between two adjacent blades 34 always faces the operator's breathing zone, thereby ensuring that the operator's breathing zone is always filled with fresh air. Furthermore, because the air in the air intake duct 36 is blown from the outside to the operator's breathing zone under the negative pressure of the exhaust mechanism 9, the generated smoke and dust float upwards and flows to the exhaust louver regulating valve 4, which will not pollute the operator's breathing zone and ensure the operator's safety.

[0052] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
