Description

Technical Field

[0001] The utility model relates to the technical field of ventilation, in particular to a ventilation device for a pulping workshop. Background Art

[0002] Pulp mill ventilation plays a key role in protecting worker health and product quality. The following are the main functions of pulp mill ventilation:

[0003] Improve air quality

[0004] The ventilation system ensures that the air quality in the workshop meets the hygiene standards by exhausting the dirty air in the workshop and introducing fresh air or treated air. This is crucial to prevent the accumulation of harmful gases, dust and steam.

[0005] Control of Hazardous Substances

[0006] In the pulping workshop, various harmful substances may be generated, including dust, chemical gas and steam. The ventilation system can effectively control the spread of these harmful substances and protect the health of workers through local ventilation or comprehensive ventilation.

[0007] Provide a comfortable working environment

[0008] Proper ventilation can regulate the temperature and humidity in the workshop, providing a more comfortable working environment. This not only helps improve worker efficiency, but also reduces health problems caused by poor working conditions.

[0009] Meet environmental requirements

[0010] Through the ventilation system, the exhausted air can be purified to ensure that it does not pollute the surrounding environment. This meets the requirements of environmental protection and is also conducive to the sustainable development of the enterprise.

[0011] Ensure product quality

[0012] In the pulping workshop, pollutants in the air may affect the quality of the product. Through an effective ventilation system, the cleanliness in the workshop can be controlled to ensure the production of high-quality products.

[0013] However, most of the existing ventilation devices directly use fans as the power of the ventilation system to drive air circulation. However, since the ventilation devices cannot be easily replaced and moved after installation, a single set of ventilation devices can only achieve ventilation of local locations. Even if ventilation of different locations is achieved through the arrangement of ventilation ducts, most of the ventilation ducts are not easy to move. Utility Model Content

[0031] See also Figure 1-Figure 7 The utility model provides a technical solution: a ventilation device for a pulping workshop, comprising a mounting frame 1 and a cover plate 11, a diversion slot 2 is provided on the top of the mounting frame 1, a wind guide slot 3 is provided on the inner bottom of the diversion slot 2, an exhaust slot 4 is provided on the inner bottom of the wind guide slot 3, a plurality of exhaust holes 5 are provided at equal intervals through the inner bottom of the exhaust slot 4, a motor 6 is fixedly installed inside the wind guide slot 3 through a fixed frame, and a fan blade 7 is connected to the output end of the motor 6;

[0032] The cover plate 11 is sleeved on the top of the mounting frame 1. A plurality of air inlet holes 13 are opened at equal intervals through the top of the cover plate 11. An externally threaded sleeve 14 is fixedly connected to the top of the cover plate 11 corresponding to the position of each air inlet hole 13. The externally threaded sleeve 14 is connected to the air inlet hole 13. An internally threaded sleeve 17 is threadedly sleeved on the outer wall of the externally threaded sleeve 14. A gooseneck tube 18 is fixedly connected to the top of the internally threaded sleeve 17. The other end of the gooseneck tube 18 is fixedly connected to a support frame 19. A matching through groove is opened through the top of the support frame 19 corresponding to the gooseneck tube 18.

[0033] The exhaust hole 5 has a conical structure, and the diameter of the exhaust hole 5 at the end away from the motor 6 is larger than the diameter of the exhaust hole 5 at the end close to the motor 6. The exhaust hole 5 with a gradually increasing diameter can effectively prevent dust from being blocked inside the hole, thereby making it easy to discharge dust inside the exhaust hole 5.

[0034] A diverter plate 8 is provided inside the diverter trough 2, and mounting blocks 9 are fixedly connected on all four sides of the diverter plate 8. A matching mounting groove 10 is opened on the inner wall of the diverter trough 2 corresponding to the mounting block 9, and the mounting block 9 is embedded in the inside of the mounting groove 10. The diverter plate 8 installed inside the diverter trough 2 can divert the gas so that the flow rate of each gooseneck tube 18 is the same.

[0035] A plurality of bolts 12 are evenly spaced on the outer wall around the cover plate 11, and the bolts 12 pass through one end of the cover plate 11 and are threadedly connected to the outer wall of the mounting frame 1. The cover plate 11 is detachably mounted on the mounting frame 1 by the bolts 12, which facilitates the disassembly, assembly and maintenance of the cover plate 11.

[0036] A plurality of support rods 15 are fixedly connected to the top of the cover plate 11 at equal intervals, a first magnet block 16 is fixedly connected to the top of the support rod 15, a second magnet block 20 is embedded in the bottom of the support frame 19 corresponding to the adjacent first magnet block 16, the second magnet block 20 is adapted to be arranged to match the first magnet block 16, and the second magnet block 20 at the bottom of the support frame 19 can be magnetically adsorbed on the first magnet block 16 at the top of the support rod 15, thereby providing stable support for the gooseneck 18 through the support frame 19.

[0037] Specifically, when using the utility model, the motor 6 is installed inside the air guide slot 3 through the fixed frame, and the mounting block 9 on the splitter plate 8 is aligned with the mounting slot 10, so that the splitter plate 8 is installed inside the splitter slot 2, and then the cover plate 11 is buckled on the top of the mounting frame 1 and locked by the bolt 12, and finally the internal threaded sleeve 17 is threadedly sleeved on the external threaded sleeve 14, so that the gooseneck 18 is connected with the air inlet 13, the splitter slot 2 and the air guide slot 3 are connected with the exhaust slot 4 and the exhaust hole 5;

[0038] The support frame 19 is magnetically attached to the first magnet block 16 on the support rod 15 through the second magnet block 20, so that the gooseneck tube 18 is supported by the support frame 19;

[0039] When in use, the mounting bracket 1 is mounted in the ventilation slot provided on the wall to install the device. After the installation is completed, the motor 6 is started by connecting an external power source. When the motor 6 is started, the fan blades 7 can be driven to rotate. When the fan blades 7 rotate, the air inside the diverter slot 2 can be driven along the air guide slot 3 toward the exhaust slot 4, thereby driving the indoor air to be discharged from the exhaust hole 5 through the gooseneck 18, the air inlet 13, the diverter slot 2, the air guide slot 3 and the exhaust slot 4. When ventilation is required in different areas, the support bracket 19 is removed from the support rod 15, so that the retractable gooseneck 18 can be driven to extend, as shown in the attached figure. Figure 6 As shown in FIG. 1 , at this time, the other gooseneck tubes 18 are still in a contracted state. When multiple groups of gooseneck tubes 18 are not needed for ventilation, as shown in FIG. Figure 7 As shown in the figure, a buckle cover is buckled on the support frame 19 on the gooseneck tube 18 that is not in use, so as to close the gooseneck tube 18 that is not in use, and the ventilation effect of the gooseneck tube 18 in use can be correspondingly enhanced without changing the power of the motor 6, and the ventilation position can be freely adjusted according to demand, so that the ventilation device can freely ventilate different positions according to demand.
