[0018] Please see Figure 1-2 A vibratory fluorine gas dust collector includes a cylinder 1, a cover plate 2, a vibrating device 7, and a control system 8. The cover plate 2 is connected to the cylinder 1 by bolts. The cylinder 1 has an air inlet 3 on one side and an air outlet 4 on the other side. A filter screen 6 is installed inside the cylinder 1. A slag outlet 5 is located at the bottom of the side of the cylinder 1. Three support seats 9 are fixedly connected to the bottom of the cylinder 1. The vibrating device 7 is located on the top of the cover plate 2, with its output end extending into the cylinder 1 and contacting the top of the filter screen 6.

[0021] Filter performance: Filter accuracy ≤40μm, filter volume 500m 3 / h·m 2 ,

[0022] Manufacturing requirements:

[0023] The forgings shall meet the requirements of Grade IV in NB / T47008-2010 "Carbon and Alloy Steel Forgings for Pressure Equipment",

[0024] All structural components shall be welded with full penetration welding and polished after welding.

[0025] The welding of the flange (WN necked butt welding flange) to the corresponding nozzle and each component shall be carried out in accordance with the provisions of Figure 9.4 "Welding Joint of Necked Butt Welding Flange and Steel Pipe" in Article 9.4.2 of HG / 20592 standard. The fillet weld height shall not be less than 6mm.

[0026] The nozzle material shall meet the requirements in NB / T47018.1~47018.7-2011 "Technical Requirements for Ordering Welding Materials for Pressure Equipment".

[0027] There shall be no impurities such as oil stains, moisture, rust, etc. in the inner cavity (including nozzles and internals) of this equipment. It shall be wiped with a lint-free white fine cloth, and no stains shall be left to be qualified. After passing the inspection, each nozzle shall be blocked with a blind plate.

[0028] After debugging and locking at the used slotted nut, corresponding split pin holes (M16 pin hole 4) shall be made on the corresponding screw. After drilling, ensure that the nut can be screwed smoothly.

[0029] Working Principle: The equipment is placed in the designated location and supported by the support base 9. After connecting to 220V AC power, fluorine gas enters the cylinder 1 through the inlet 3 and is filtered by the 316L stainless steel sintered filter screen 6 (pore size 30-40μm). Clean gas is discharged from the outlet 4. Particulate impurities produced during filtration settle at the bottom of the cylinder 1 and can be periodically discharged through the slag outlet 5. The PLC controller (model S7-200 SMART) in the control system 8 operates according to a preset program: When the differential pressure sensor detects a pressure difference exceeding 500Pa across the filter screen, it outputs a command to the electromagnetic vibrator 7 (model ZJ-100, power 50W). This vibrator, via a cam mechanism, drives the vibrating rod to reciprocate up and down at a frequency of 20-50Hz and an amplitude of 0.5-2mm, causing the filter screen 6 to resonate. This causes adhering media particles to detach, preventing filter screen 6 from clogging and ensuring normal operation of the equipment. This structure can effectively filter media particles smaller than 40μm, ensuring the purity of gas separation; the filtration volume can reach 500m³. 3 / h·m 2 It meets the needs of large-scale fluorine gas separation; it adopts CPU control, motor power 0.55W, voltage 220V, supports manual / automatic dual mode switching, realizes remote control function, can accurately control the filtration process, and improve the safety and reliability of equipment operation.

[0030] The anti-slip effect of the bottom of the support base 9 is poor. When the bottom of the support base 9 comes into contact with the smooth ground, it is easy to slip. In order to solve this problem, in this embodiment, the bottom of the support base 9 is provided with an anti-slip layer, and the anti-slip layer is fixedly connected to the bottom of the support base 9.

[0031] To improve the anti-slip effect, in this embodiment, the bottom of the anti-slip layer is provided with diamond-shaped anti-slip patterns with a spacing of 3-5mm and a depth of 1-1.5mm, which are evenly distributed along the bottom surface of the support base 9. According to the friction coefficient test, this design can achieve a dry friction coefficient of 0.92 and a wet friction coefficient of 0.81, which is more than 40% better than the design without patterns. The anti-slip patterns are integrally processed with the silicone rubber anti-slip layer by molding process, and the edges of the patterns are rounded (R0.2mm) to avoid stress concentration and cracking of the patterns, ensuring stable anti-slip effect during long-term use.

[0032] To improve the connection effect, in this embodiment, the cover plate 2 and the cylinder 1 are connected by three bolts. The three bolts are arranged symmetrically around the cylinder axis (e.g., evenly distributed around the circumference of the Ф100mm bolt holes). Each bolt is an M8×30 ​​stainless steel bolt (material 304), with spring washers for anti-loosening. The tightening torque is controlled within the range of 0.8-1.2 N·m. By applying force evenly with a torque wrench, the sealing gasket (metal spiral wound gasket) between the cover plate and the cylinder is subjected to uniform pressure, and the leakage rate of the sealing surface is ≤1×10. -9 Pa·m3 / s, ensuring no fluorine gas leakage, the symmetrically arranged bolt groups can make the connection structure bear uniform axial force, avoiding the deformation of the cover plate caused by local stress concentration. According to finite element analysis, this design can control the maximum deformation of the cover plate within 0.1mm.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
