Description

Technical Field

[0001] This utility model relates to the field of workshop air curtain dust suppression, and in particular to a workshop air curtain dust suppression device. Background Technology

[0002] In industrial production, dust generation in workshops remains a critical issue requiring immediate attention. Workshop air curtain dust suppression systems play a vital role in this process. These systems primarily create an air barrier at workshop entrances and exits, effectively preventing the entry of dust-laden air from the outside. Simultaneously, in conjunction with a spray dust suppression system, atomized water droplets are dispersed into the workshop air, causing dust particles to combine with the water droplets and settle to the ground under gravity, thus reducing the dust concentration in the workshop air. This effect is significant for protecting the health of workers in the workshop, significantly reducing the risk of various occupational diseases caused by long-term dust inhalation. Furthermore, a stable and low dust concentration helps ensure the normal operation of production equipment, reducing the probability of equipment malfunctions due to dust accumulation, thereby improving production efficiency, ensuring product quality stability, and enhancing the overall economic benefits of the enterprise.

[0003] However, existing workshop air curtain dust suppression devices have many shortcomings. The air curtain formation in some traditional devices is not stable enough, making it difficult to cope with the complex and ever-changing airflow in the workshop environment. This results in gaps or weak areas in the air curtain, allowing external dust to still enter the workshop. Some spray dust suppression components have limited spray coverage, failing to evenly distribute the spray across the entire workshop space, resulting in still high dust concentrations in some areas and significantly reducing the dust suppression effect. Furthermore, in the dust collection stage, most devices lack efficient collection and cleaning designs, allowing dust to easily be re-ignited during collection, causing secondary pollution. This not only fails to effectively reduce dust concentration but may also worsen workshop air quality, affecting normal production activities and the health of workers. Utility Model Content

The output end of the water pump 8 is connected to the connecting pipe 5, and the gas and liquid pipelines are combined through a three-way connector. A filter screen 9 is provided inside the water tank 7. The filter screen 9 is made of stainless steel and has a pore size of 50μm, which can effectively filter mud, sand, impurities, etc. in the water. A fixing rod 10 is fixedly connected to the upper right side of the base 1. The surface of the fixing rod 10 is engraved with scale markings 18 with an accuracy of 1cm for accurate positioning. The sliding... The rail 11 is fixedly connected to the fixed rod 10. The rail 11 is a ball bearing type rail, which has low sliding resistance and accurate positioning. A slider 12 is slidably connected to the rail 11. A locking bolt is provided between the slider 12 and the rail 11 to fix the adjusted position. A collection groove 13 is fixedly connected to the slider 12. The collection groove 13 is made of plastic and has a smooth inner wall for easy cleaning.

The bottom of the inclined end is provided with a detachable drain port.

[0022] like Figures 1 to 4 As shown, the specific structure of the air curtain mechanism 4 includes a housing 41, a motor 42, a rotating shaft 43, blades 44, and an air outlet 45. The housing 41 is fixedly connected to the top of the support 2. The housing 41 is made of die-cast aluminum alloy, which is lightweight and high-strength, and the surface is treated with anti-corrosion. The motor 42 is fixedly connected inside the housing 41. The motor 42 is a servo motor, and the speed can be adjusted within the range of 0-1500 r / min to adapt to different air curtain intensity requirements. The rotating shaft 43 is fixedly connected to the output shaft of the motor 42. The rotating shaft 43 is made of No. 45 steel and the surface is heat-treated to improve wear resistance. Multiple blades 44 are fixedly connected to the rotating shaft 43. There are 6 blades 44 in total, which are symmetrically distributed and have an arc design to improve airflow guidance efficiency. The lower end of the housing 41 is provided with an air outlet 45. The air outlet 45 is long and narrow, with a width of 5 cm. The length is adapted to the width of the workshop entrance and exit. The interior is provided with a guide grille to optimize the shape of the air curtain. The motor 42 is connected to the shaft 43 by a reducer 46, which is a planetary gear reducer with a reduction ratio of 1:5. This reducer converts the high-speed rotation of the motor 42 into a stable low-speed rotation of the shaft 43. The input end of the reducer 46 is fixedly connected to the output shaft of the motor 42, and the output end of the reducer 46 is fixedly connected to the shaft 43. The connection uses a keyway structure to transmit torque. The surface of the blade 44 is provided with multiple flow guide protrusions 47. The flow guide protrusions 47 are hemispherical with a diameter of 3 mm and a spacing of 5 mm. The flow guide protrusions 47 and the blade 44 are integrally injection molded to enhance the stability and uniformity of the airflow.

[0023] The usage of this utility model is as follows: First, based on the characteristics of the dust pollution area in the workshop and the location of the entrance and exit, the workshop air curtain dust suppression device is placed in a suitable position using the base 1. The bottom of the base 1 can be fixed to the ground with expansion bolts to prevent shaking during operation. The device is then connected to an external 380V industrial power supply and the workshop control system via connector 15 to complete power connection and signal debugging, ensuring that components such as the fan 3, water pump 8, and motor 42 can respond normally to control commands. The start switch corresponding to connector 15 is activated, and the fan 3 begins to work first, drawing in and pressurizing outside air, which is then stably delivered to the housing 41 of the air curtain mechanism 4 through the connecting pipe 5. In the air curtain mechanism 4, the motor 42 is powered on and started under the control of the control system. The high-speed rotation of its output shaft is reduced by the reducer 46 and drives the rotating shaft 43 to rotate at a preset speed, usually 300-500 r / min. The rotating shaft 43 synchronously drives the six blades 44 fixed on the surface to rotate. The guide protrusions 47 on the surface of the blades 44 divide and guide the airflow, so that the turbulent airflow is transformed into a laminar flow state, and finally a stable and uniform air curtain is formed. The air curtain is discharged downward from the air outlet 45 at a wind speed of 15-20 m / s, building an invisible air barrier at the entrance and exit of the workshop or on the dust diffusion path, effectively blocking the cross-flow of air inside and outside the workshop, greatly reducing the entry of dusty air from the outside into the workshop, and inhibiting the diffusion of dust inside the workshop to the outside.

[0024] Simultaneously, water pump 8 starts synchronously under the linkage of the control system, drawing clean water stored in water tank 7. The water first passes through filter screen 9 to remove pollutants such as mud, sand, impurities, and microorganisms, preventing impurities from entering the nozzles 6 and causing nozzle blockage. The filtered clean water is then transported to the nozzles 6 below the air curtain mechanism 4 via a branch pipe of connecting pipe 5. Under the action of high-pressure water flow, nozzles 6 atomize the clean water into fine water droplets with a diameter of 5-10μm. These droplets are evenly diffused into the air in the workshop by the air curtain airflow. Suspended dust particles in the workshop, especially inhalable dust with a diameter of 0.5-10μm, collide and contact with the atomized water droplets, forming particle clusters with a density greater than that of air. Under the action of gravity, these clusters gradually fall downwards and finally fall precisely into the collection tank 13 for centralized collection. During this process, filter screen 9 in water tank 7 can be disassembled and cleaned periodically to ensure the continuity of the filtration effect, thereby ensuring the stability and coverage of the spray from nozzles 6 and preventing local dust concentration from exceeding the standard due to uneven spraying.

[0025] The water level detection rod 16 inside the water tank 7 monitors the water level changes in the tank 7 in real time. When the water level drops to the preset minimum water level line (usually 1 / 5 of the tank volume) due to dust suppression spraying, the water level detection rod 16 immediately sends a low water level signal to the workshop control system. The system triggers an audible and visual alarm, reminding staff to open the water inlet of the water tank 7 to add clean water. During the replenishment process, the amount of water added can be controlled by the real-time feedback from the water level detection rod 16 to avoid overfilling and overflow. During use, the 15° inclined surface 17 at the bottom of the collection tank 13 causes dust particles falling into the tank to automatically converge towards the inclined end under gravity. When the dust accumulates to a certain amount, staff can open the drain port at the bottom of the inclined end to quickly discharge the accumulated dust into the collection bag, greatly improving cleaning efficiency. The baffle 14 at the front end of the collection tank 13 can effectively block dust generated by tool contact during cleaning and prevent dust from overflowing from the tank opening due to airflow disturbance in the workshop, thus avoiding secondary pollution. In addition, to accommodate differences in dust settling height, ground flatness, and equipment layout in different workshops, staff can loosen the locking bolts on slider 12 and push slider 12 up and down along slide rail 11 on fixed rod 10. Combined with the scale markings 18 on fixed rod 10, the collection tank 13 can be adjusted to the optimal collection height, usually 30-50cm from the ground. After adjustment, tighten the locking bolts to fix the position, making the device adaptable to diverse workshop environments and further improving the device's practicality and applicability.
