Description

Technical Field

[0001] This utility model belongs to the technical field of papermaking equipment, specifically relating to online dust detection equipment for papermaking. Background Technology

[0002] Online dust monitoring equipment for papermaking is a real-time monitoring system designed to address dust pollution issues generated during the papermaking process. In the papermaking process, a large amount of fine particulate matter is easily generated in the processes of raw material crushing, pulping, drying, and paper cutting. In particular, the pulping process in recycled paper production is more likely to generate high concentrations of dust. The system can continuously monitor the dust concentration in key locations such as production workshops and material storage areas online.

[0003] Currently, in the high temperature and high humidity conditions of papermaking workshops, the narrow-spacing structure of the heat dissipation fins on the equipment casing easily attracts paper fibers floating in the air. These fibers gradually accumulate in layers to form a dense insulation layer. Under the action of high-temperature steam, the fiber layer will physically bond together, eventually forming a dense covering layer similar to a non-woven fabric structure. This hidden dust accumulation will cause the electronic components of the equipment to be in an overheated working state for a long time, accelerating circuit aging and potentially causing measurement drift.

Those skilled in the art can make similar extensions without departing from the spirit of the present invention.

[0030] Example

[0031] Reference Figures 1-4 This is an embodiment of the present invention, which provides an online detection device for papermaking dust, including,

[0032] The support mechanism 100 includes a base 110, a bracket 120 fixedly installed on the top of the base 110, and an adjustment component 130 disposed on the top of the bracket 120.

[0033] The cleaning mechanism 200 includes a housing 210, a soot blowing assembly 220 disposed in the inner cavity of the housing 210, and a fixing assembly 230 disposed in the inner cavity of the housing 210.

[0034] The soot blowing assembly 220 includes a protective shell 221 fixedly installed on the outside of the housing 210, a fixing seat 222 fixedly installed in the inner cavity of the protective shell 221, a fan 223 fixedly installed at the bottom of the fixing seat 222, and a connecting pipe 224 fixedly installed at the bottom of the fan 223.

[0035] And, the testing mechanism 300 used in conjunction with the bearing mechanism 100.

[0036] The modular design of the support mechanism 100 and the cleaning mechanism 200 enables the separation of stable installation and automatic maintenance functions of the testing equipment. The bracket 120 and the adjustment component 130 form an expandable support frame, while the dust blowing component 220 integrated in the housing 210 can independently complete the cleaning operation, which greatly reduces the overall maintenance complexity of the equipment.

[0037] Specifically, the cleaning mechanism 200 also includes heat dissipation fins 240 disposed in the inner cavity of the housing 210, heat dissipation vents 250 opened at the bottom of the housing 210, and a dustproof mesh 260 fixedly installed in the inner cavity of the heat dissipation vents 250.

[0038] The combination of heat dissipation fins 240 and dustproof net 260 forms a dual protection system. The bottom layout of heat dissipation port 250, together with the interception function of dustproof net 260, not only ensures the smooth flow of heat dissipation airflow, but also effectively prevents large particulate pollutants from entering the equipment, significantly improving the long-term operational reliability in the high dust environment of paper mills.

[0039] Furthermore, the dust blowing assembly 220 also includes an air jet plate 225 fixedly installed at the bottom of the connecting pipe 224, an air blowing port 226 opened on the outside of the air jet plate 225, and a dust sensor 227 fixedly installed in the inner cavity of the protective shell 221.

[0040] The multi-point air outlet 226 design of the jet plate 225, combined with the feedback from the dust sensor 227, enables precise directional cleaning. It can intelligently adjust the blowing force according to the actual dust accumulation, which not only avoids energy waste but also ensures that the surface of the heat dissipation fins 240 is always in the best heat dissipation state.

[0041] Preferably, the fixing component 230 includes a card holder 231 fixedly installed in the inner cavity of the housing 210, a card slot 232 formed at the bottom of the card holder 231, and a magnetic block 233 fixedly installed in the inner cavity of the card slot 232 for fixing the heat dissipation fins 240.

[0042] The magnetic block 233 and the card slot 232 work together to create a quick-release heat dissipation module. The card holder 231 provides mechanical positioning protection, while the magnetic fixing method makes the replacement of the heat dissipation fins 240 as simple as replacing a battery. On-site personnel can complete the maintenance without tools.

[0043] It should be noted that the adjustment assembly 130 includes a support frame 131 fixedly installed on the top of the bracket 120, and a linear moving guide rail 132 fixedly installed inside the support frame 131. The adjustment assembly 130 also includes a moving plate 133 disposed on the top of the linear moving guide rail 132, and a drive motor 134 fixedly installed on the outside of the support frame 131 to drive the linear moving guide rail 132 to move. The housing 210 is fixedly installed on the bottom of the moving plate 133.

[0044] The embedded layout of the linear moving guide rail 132 within the support frame 131 enables precise three-dimensional spatial positioning of the detection unit. This not only resists vibration interference from papermaking machinery but also provides a smooth moving trajectory for the detection probe 340, ensuring the spatial representativeness of the sampled data. The direct drive between the drive motor 134 and the moving plate 133 constitutes a maintenance-free motion system. The external motor design facilitates maintenance and prevents dust from entering the transmission components. Simultaneously, the overall displacement of the moving plate 133 drives the detection mechanism 300 and the cleaning mechanism 200 to move synchronously, achieving collaborative operation of detection and cleaning.

[0045] Furthermore, the detection mechanism 300 includes a vertical rod 310 fixedly installed on the top of the movable plate 133, a horizontal plate 320 fixedly installed on the outside of the vertical rod 310, a controller 330 fixedly installed on the top of the horizontal plate 320, and a detection probe 340 fixedly installed on the bottom of the horizontal plate 320.

[0046] Among them, the cantilever structure composed of the vertical rod 310 and the horizontal plate 320 optimizes the spatial orientation of the detection probe 340, the top mounting of the controller 330 is both far away from the pollution source and easy to operate manually, and the suspended layout of the detection probe 340 allows it to avoid the airflow vortex area and obtain more representative dust concentration data.

[0047] When the device is started, the detection probe 340 of the detection mechanism 300 moves along the linear moving guide rail 132 under the drive of the drive motor 134 to scan, collect dust data in real time and transmit it to the controller 330. At the same time, the dust sensor 227 continuously monitors the dust accumulation on the heat sink 240. When the threshold is reached, the dust blowing component 220 is automatically triggered. The fan 223 blows clean air through the air outlet 226 of the air jet plate 225. The dustproof net 260 intercepts large particulate pollutants at the same time. The heat dissipation module fixed by the magnetic block 233 is easy to replace and maintain quickly.

[0048] In summary, the robust frame of the support mechanism 100 and the precision motion system of the adjustment component 130 provide the equipment with a vibration-resistant and stable working platform. The innovative dust blowing component 220 and the quick-release heat dissipation module of the cleaning mechanism 200 form a self-maintenance system, and on-demand cleaning is achieved through feedback from the dust sensor 227. The cantilever layout of the detection mechanism 300, combined with the synchronous drive of the moving plate 133, enables the detection probe 340 to sample accurately while avoiding contamination interference.
