Description

Technical Field

[0001] The invention belongs to the technical field of carbon fiber equipment, and in particular relates to an electrical cabinet with a function of cleaning internal conductive dust. Background Art

[0002] During the carbon fiber production process, a large amount of conductive carbon filaments will be generated floating in the air; if these carbon filaments enter the interior of the cabinet, they will adhere to the electrical components, affecting their conductivity and easily causing short circuits, burning and other faults; in addition, the accumulation of carbon filaments in the filter will also affect the heat dissipation effect, causing the equipment temperature to be too high and accelerating the aging of the equipment; therefore, in order to ensure the safety and stable operation of the equipment, it is necessary to design a device that can effectively monitor the entry of carbon filaments and remove them from the cabinet; traditional electrical cabinets are mostly fan-ventilated or external air-conditioned. Once the cabinet door needs to be opened for maintenance or wiring, carbon filaments will enter, forming a potential risk, and cannot be removed, causing short circuit accidents at any time, which will not only increase maintenance costs, but may also be difficult to repair in time due to out-of-stock of some electrical components, causing greater economic losses; therefore, from the perspective of economic cost and maintenance difficulty, it is also necessary to develop a device that can monitor and remove conductive dust.

[0019] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0020] Embodiment: An electrical cabinet having a function of cleaning internal conductive dust, such as Figure 1-Figure 5 As shown, it includes a cabinet 1, a monitoring component and a cleaning component, and is characterized in that: a partition 2 is provided in the middle upper position inside the cabinet 1, a mounting hole 3 is opened on the side wall of the cabinet 1, the cleaning component is arranged on the partition 2, and the detection component is arranged in the mounting hole 3.

[0021] The detection component includes a cooling fan 4, a filter element component 5 and a carbon filament monitoring device 20. The cooling fan 4 is fixed in the mounting hole 3. The cooling fan 4, the filter element component 5 and the carbon filament monitoring device 20 are installed in the order of the cooling fan 4 being installed on the outermost side, the carbon filament monitoring device 20 being installed on the innermost side, and the filter element component 5 being installed between the two.

[0022] The cleaning assembly includes a first one-way valve 6, a circulation fan 7, a filter bag 8, a second one-way valve 9, a mounting tube shell 10 and an air guide tube shell 11. The right end of the mounting tube shell 10 is bent downward and is arranged in an L-shape as a whole. The first one-way valve 6 is arranged at the left end inlet of the mounting tube shell 10, and the circulation fan 7 and the filter bag 8 are installed to the right in sequence. The second one-way valve 9 is arranged at the downward pipe opening of the right end of the mounting tube shell 10. The top of the guide air shell is connected to the right end of the mounting tube shell 10, and the lower end extends through the partition 2 to the bottom of the cabinet 1, and an air outlet 12 is opened at the end.

[0023] The first one-way valve 6 and the second one-way valve 9 have the same structure, and both include a rectangular mounting frame 13. A circular ventilation duct 14 is provided in the middle of the rectangular mounting frame 13. A support rod 15 is provided on the circular ventilation duct 14. A flap 16 is symmetrically provided on the left and right sides of the support rod 15. The flap 16 is rotatably connected to the rectangular mounting frame 13. A sealing tape 17 is connected between the front ends of the two flaps 16. Leaf springs 18 for resetting the flap 16 are provided in the circular ventilation ducts 14 at the upper and lower ends of the support rod 15.

[0024] The carbon filament monitoring device 20 includes a mounting bracket 19, which includes two A-pole meshes 21 and one B-pole mesh 22.

The two A-pole meshes 21 are connected to one pole of the power supply, and the B-pole mesh 22 is connected to one pole of the power supply.

[0025] The present invention can effectively monitor whether the intake air contains conductive dust by fixing the carbon filament monitoring device 20 on the cabinet 1 through insulating bolts. For example, if the carbon filaments enter through the filter screen unqualifiedly, they will overlap the A and B plates in the carbon filament monitoring device 20, triggering the delay relay coil KT1 in the control circuit and activating the circulation fan 7. At this time, due to the effect of wind force, the flaps 16 in the first one-way valve 6 and the second one-way valve 9 are pushed open by the wind force. The delay relay can be set for 10 minutes to clear the carbon filaments in the cabinet. When the carbon filament cleaning is completed, the flaps 16 in the first one-way valve 6 and the second one-way valve 9 are reset to the original position by the leaf spring 18 due to the stop of the circulation fan 7, and the installation tube shell 10 is sealed, so that the filter bag 8 can be replaced, and the equipment can also clean the carbon filaments in the cabinet regularly by manually starting the knob;

[0026] By adjusting the distance between the three mesh plates A and B, the effectiveness of monitoring different particle sizes or carbon filaments can be effectively monitored, and the purpose of removing conductive dust of different particle sizes can be achieved by purchasing filter bags with different mesh sizes.
