Description

Technical Field

[0001] This utility model belongs to the field of smoke and dust collection technology, specifically referring to an integrated mobile smoke and dust collection device. Background Technology

[0002] Industrial workshops require the collection of toxic and harmful fumes and dust generated during the welding, cutting, and grinding processes of long, heavy, and large components lifted by overhead cranes. Current collection methods often employ mobile suction arms or mobile suction hoods. Mobile suction arms require operators to move them while working, otherwise, they cannot effectively collect the generated fumes and dust. Furthermore, moving the suction arm while working disrupts the continuity of operations, affecting product quality and operator efficiency. Additionally, they are often abandoned due to operator subjectivity. Mobile suction hoods typically use rotation or translation. Rotation has a certain radius; when the workpiece length exceeds 10 meters, the rotation radius needs to be sufficiently large to avoid the workpiece. Meanwhile, larger suction hoods have higher requirements for stress resistance, load-bearing capacity, and material strength. Rotating hoods are usually suitable within a length range of 4 meters. If a translation method is used, a support structure needs to be set up to suspend the suction hood in the air. If the workpiece is 10 meters or more long and 5 meters or more wide, the material strength, load-bearing capacity, durability, and safety factors also need to be considered when setting up such a translation suction hood. At the same time, operators need to participate in the operation of rotating or moving the suction hood, and they need to constantly observe whether there are collisions or interference problems during the rotation or movement. Therefore, the safety applicability is not high.

[0003] The aforementioned methods of collecting fumes and dust generated during welding, cutting, and grinding operations in industrial processing plants using mobile suction arms or hoods primarily rely on localized treatment (source capture) of harmful fumes and dust. The efficiency of fume and dust collection, assuming the suction velocity meets design requirements, largely depends on whether the suction port covers the pollution source and whether personnel are moving while working. Even with standardized localized collection methods, some fumes and dust cannot be collected in a timely manner, leading to severe air pollution in the working environment and harming the physical and mental health of workers. Therefore, this utility model, an integrated mobile fume and dust collection device, has emerged to address the problem of ineffective or impossible localized collection methods for welding, cutting, and grinding operations involving large parts (such as in large vehicle manufacturing, shipbuilding, construction machinery, petrochemical equipment, and mining machinery). The efficiency of dust collection directly affects the overall processing efficiency of the purification system. The integrated mobile dust collection device solves this problem. It not only has a collection efficiency of over 90%, but also does not affect on-site operation methods or product quality. It encloses the dust produced in a certain space, preventing the dust from floating and spreading, affecting the overall environment of the workshop and causing secondary pollution in other work areas.

The top of the maintenance ladder 16 is at the same height as or 0.5-1.2m higher than the top surface of the protective cover 1. The bottom of the maintenance ladder 16 is 0-1m above the ground. The audible and visual alarm is installed at the top of the protective cover 1.

[0025] In a further embodiment of this example, a protective railing is provided at the top side of the protective cover 1. The protective railing includes a foot plate 171, a fixing base 172, a vertical pole 173, and a horizontal bar 174. The fixed base 172 is connected to the protective cover 1, the bottom end of the upright 173 is connected to the fixed base 172, the upright 173 is connected to the crossbar 174, and the uprights 173 on the same crossbar 174 are evenly arranged.

[0026] In a further embodiment of this example, the fixing seats 172 are evenly distributed on the top side of the protective cover 1, and two adjacent crossbars 174 are vertically connected to the uprights 173 at the corners via a tee.

[0027] In a further embodiment of this example, the size of the protective cover 1 is (13-14m)*(12-13m)*(5-5.5m), the number of the reduction motors is four, and the reduction motors are respectively set at the four corners of the bottom of the protective cover 1. The power of the reduction motors is 2.2-3.0KW, and the total operating power is 10.4-13.6KW.

[0028] In a further embodiment of this example, the maintenance ladder 16 is provided with a protective cage 161, the bottom of the protective cage 161 is 2-2.5m higher than the bottom of the maintenance ladder 16, and the top of the protective cage 161 is 0.5-1m higher than the top surface of the protective cover 1.

[0029] In a further embodiment of this example, the duct assembly includes a main pipe 41, branch pipes 42 and interface pipes 43. The air inlets 12 are connected to the interface pipes 43 one by one. Multiple interface pipes 43 are connected to the corresponding branch pipes 42.

[0030] In a further embodiment of this example, the protective cover 1 has a drive motor on the top side of the electric lifting door 11, the protective cover 1 has a through groove on the side of the electric lifting door 11, the through groove has a door groove 112 on the side, the electric lifting door 11 is connected in the door groove 112, and the drive motor is connected to and drives the electric lifting door 11.

[0031] It should be noted that the integrated mobile fume collection device is "integrated," meaning that half of the work area is completely enclosed. "Mobile" refers to the fact that two tracks are installed on both sides of the work area for the integrated mobile fume collection device to move. During welding, the integrated mobile device is moved above the welding area via remote control or operation from the electrical control cabinet, thus enclosing the work area. Welding, cutting, and grinding operations are carried out within this enclosed space. The generated fumes and dust are collected and purified through negative pressure suction and a pre-reserved open area on the ground via a lift-up door, creating airflow. To ensure uniform negative pressure throughout the enclosed space, multiple air inlets 12 are designed at the top, with diffusers at the inlets to gather and draw the fumes and dust into the negative pressure duct assembly.

[0032] When the entire operation is completed and the workpiece needs to be moved by a crane, the collection device can be moved to the other end of the work area (i.e., the original unenclosed half of the work area) by remote control button or operation of the electrical control cabinet. At this time, the workpiece can be hoisted. The whole process only requires the operator to operate the button. It is safe and practical, and the collection efficiency of smoke and dust is high. There is almost no smoke and dust escaping and diffusion. It can completely collect all the smoke and dust in the enclosed space and achieve true source collection and treatment.

[0033] The collection device can also be equipped with several optional features: indoor and outdoor camera monitoring to provide real-time updates on the situation inside and outside the room; it can also detect obstacles during movement and display real-time images of the number of workers, work methods, and work locations within the collection device; the collection device can also be equipped with a smoke and dust concentration meter for real-time monitoring, a temperature and humidity sensor for real-time monitoring, and a fingerprint unlocking system to prevent unauthorized operation.

[0034] This allows for the enclosure of the work area to meet all complex working conditions, and provides real-time display of the working situation inside and outside the enclosure, as well as environmental conditions such as smoke and dust concentration, temperature, and humidity. This provides personnel with a clean and comfortable working environment without affecting product quality or worker efficiency. The entire operation and smoke and dust collection process requires minimal human intervention, and the collection of smoke and dust is no longer limited by the subjectivity of the operators.

[0035] An integrated mobile collection device, as the name suggests, is a smoke and dust collection device that can move back and forth within an enclosed space. It can be used to collect smoke and dust generated by ultra-large workpieces (such as those in the shipbuilding industry, subway vehicles, mining machinery, and construction machinery industries) under various working conditions such as welding, cutting, and grinding operations.

[0036] When the workpiece is hoisted in the work area, the collection device can be moved to cover the workpiece and the work can be carried out in this enclosed space. During the operation, the collection device is always above the work area to cover the workpiece. The smoke and dust generated during the operation are always in this enclosed space. The dust-laden air in the enclosed space is extracted by the negative pressure suction generated by the dust removal fan and sent to the dust collector for filtration and purification through the air duct assembly. The purified clean airflow can be selectively discharged outdoors at high altitude or discharged into the work workshop, which must meet the corresponding pollutant control standards.

[0037] When the workpiece is completed and needs to be lifted out of the work area, the collecting device is moved away from the top of the work area to the other end of the track. At this time, the workpiece can be lifted and moved out of the work area by a crane, thus realizing the hoisting of the workpiece. The whole process does not require much human intervention; the above actions can be completed simply by operating the buttons.

[0038] The collection device is equipped with audible and visual alarms during movement to constantly remind operators to pay attention to on-site safety and avoid collisions or interference with obstacles. The collection device adopts a welded steel frame, with white cleanroom panels on the outside, which serve to provide flame retardancy, sound insulation, and heat preservation. An LED lighting lamp 14 is installed at the top, and an integrated electric lifting door 11 is installed on both sides of the vertical track. The door has a reserved air intake at the ground. By drawing air from the top and filling the reserved space at the bottom of the electric lifting door on both sides, an airflow organization pattern of downward supply and upward extraction is formed, thereby collecting the generated smoke and dust. It can handle any workpiece within the maximum size range, regardless of the operation method, operation position, or changes in the shape and size of the workpiece. As long as the workpiece generates smoke and dust in this enclosed space, it can be collected in this way. Optional measures such as dust concentration monitoring, temperature and humidity monitoring, high-definition camera, and fingerprint password control can be added to enhance the safety and applicability of the collection device.

[0039] The footprint of this utility model can be set according to the size of the work area and the maximum external dimensions of the workpiece, combined with the requirements for hoisting the workpiece. On-site, for a welding workpiece that is 11 meters long and 2 meters wide, and requires a crane to lift and rotate the workpiece, the overall mobile collection device is designed with the following external dimensions: 12600 (left and right) * 13000 mm (front and back) * 5100 mm (height and depth), and a total operating power of 10.4 KW. Each of the four corners is equipped with a 2.2 KW geared motor. The top of the collection device is designed with 16 100W LED lights and an audible and visual alarm.

[0040] Working process: After the power is turned on, operate the control panel on the electrical control box or start the equipment with the remote control. The geared motor rotates forward and backward to make the integrated mobile collection device move forward or backward. After the workpiece is hoisted into place, operate the integrated mobile collection device to directly above the workpiece and close the electric lifting door 11 and safety door 13 to form a closed space. In this space, the smoke and dust generated by welding, cutting and grinding operations are sucked in by the negative pressure of the dust collector 3 fan and evenly sucked into the dust-laden air through the air intake 12. The air is then connected to the air duct assembly and filtered and purified by the dust collector 3. At the same time, the LED lights can be turned on to facilitate internal operations. When the integrated mobile collection device needs to be maintained after a period of use, the top can be accessed through the maintenance ladder 16 and the guardrail 161. Since it is a high-altitude operation, for safety reasons, the top is equipped with toe boards 171 to prevent objects from falling. At the same time, the four sides are assembled with uprights 173, fixed seats 172, connecting tees and crossbars 174 to form a four-sided guardrail to prevent personnel from falling.

[0041] This utility model features an integrated mobile dust collection device with a fully enclosed working area, providing a sealed space that completely covers the workpiece. Dust generated during operation is prevented from escaping and is collected within this completely sealed space using negative pressure. The collection efficiency is higher than that of mobile suction hoods or mobile top suction hoods, reaching 90% or more. This collection method can handle various complex work processes and is not limited by work location; dust can be collected as long as the work is carried out within this enclosed space. Furthermore, it does not affect operator operation, eliminating the need to move the suction port while working, thus improving efficiency, and does not affect product quality, unlike mobile suction arms which require movement and disrupt the continuity of work. This design avoids impacting the overall quality of the process, better aligning with the interchangeability and quality consistency of industrial products. Unlike mobile top-mounted suction hoods, it doesn't rotate or move in the air. Its strength and stability are higher. The integrated mobile dust collection device, being ground-based, is safer and more reliable. It also avoids the swaying of the suspended curtain that occurs when a mobile top-mounted suction hood moves in the air. The longer the suspended curtain, the greater the swaying and the more uneven the force distribution, resulting in lower stability and safety for the entire mobile top-mounted suction hood. Therefore, this integrated mobile dust collection device not only boasts high collection efficiency but also offers advantages in applicability, safety, stability, and reliability compared to mobile suction arms and mobile top-mounted suction hoods, while having no impact on product quality. In addition to being applicable to welding, cutting, and grinding of ultra-large workpieces, it can also be used in areas with hoisting requirements or where work positions are concentrated but the work locations are not fixed. It solves the problem of not being able to collect smoke and dust in complex and variable work environments, and collects all smoke and dust from the source of production, truly achieving environmental protection and avoiding secondary pollution and the situation where smoke and dust cannot be collected.

[0042] This utility model relates to an integrated mobile dust collection device, applicable to various working conditions, particularly for large workpieces, work positions with uncertain locations, and situations requiring the use of a crane for workpiece movement in welding, grinding, cleaning, and blow-drying operations. Once the workpiece is hoisted to the work position, the integrated mobile dust collection device can be moved to cover the entire workpiece above the work area. Simultaneously, the electric lifting door and safety door of the integrated mobile dust collection device remain closed to achieve a sealed work area. An air intake is provided at a certain distance from the ground on the electric lifting door. After the integrated mobile dust collection device reaches its designated position, a limit switch activates... Once the dust removal and purification equipment is in place, it can be turned on. The centrifugal fan inside the equipment generates negative pressure, which is then drawn into the louvered air intake at the top of the integrated mobile dust collection device through the connecting duct assembly. This top suction and bottom replenishment of fresh air maintains a slight negative pressure within the integrated mobile dust collection device, ensuring that pollutants generated during operation do not escape and pollute the external environment. At the same time, the timely replenishment of fresh air replaces the polluted air within the entire collection device, maximizing the protection of workers and the collected polluted air, in line with current environmental protection concepts and principles. Meanwhile, the integrated mobile smoke and dust collection device can flexibly adopt a variety of sealing materials, such as flame retardant, sound insulation, smooth surface, and inner and outer steel plate cladding, to completely isolate pollutants such as noise, arc light, particulate matter, radiation, and odors in the work area from the external environment, enclosing the pollutants in an effective space. After collecting and purifying the polluted air through appropriate air intake flow, this integrated smoke and dust collection device is flexible, efficient, easy to operate, adaptable to various working conditions, and not limited by the work location, work method, workpiece shape, or material. The purified and filtered clean airflow is discharged outdoors at high altitude in accordance with current national or local environmental protection standards.
