Description

Technical Field

[0001] This utility model relates to the field of dust removal and cooling technology for electromagnetic stations, and in particular to a dust removal and cooling system device for underground electromagnetic stations. Background Technology

[0002] During production, since the electromagnetic station and the production site are located in the same area, the dust generated at the production site causes the air conditioner installed in the electromagnetic station's power distribution room to frequently malfunction and become unusable. In order to ensure that the heat generated by the electromagnetic station's power distribution equipment can be dissipated, temporary ventilation fans are installed on the walls for natural heat dissipation. However, the electromagnetic station is a closed space, and because there is no clean air entering the electromagnetic station, the ventilation fans will generate negative pressure and cannot operate. As a result, a large amount of dust accumulated after the conveyor belt system is produced enters the electromagnetic station's power distribution room through the ventilation windows. This not only affects the heat dissipation of the electromagnetic station, but also causes about 30 equipment failures per year due to the dust accumulation, increasing the waste of energy and costs due to heavy-load downtime. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a dust removal and cooling system for underground electromagnetic stations. This system solves the problem of frequent malfunctions and unusable air conditioners installed in the electromagnetic station's power distribution room due to dust, and the waste of energy and costs caused by the electromagnetic station's inability to dissipate heat, resulting in heavy-load shutdowns.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A dust removal and cooling system for an underground electromagnetic station is characterized by comprising a DN20 ball valve, a DN20 electric valve, a 0-0.8 MPa pressure regulating valve and a filter, a uniform air circulation device, a stepless speed-regulating fan, a pressure transmitter, and a controller. The DN20 ball valve is installed on a clean, fresh air supply duct in the underground chamber. The DN20 ball valve's outlet is connected to the DN20 electric valve. The DN20 electric valve's outlet is connected to the 0-0.8 MPa pressure regulating valve and the filter. The 0-0.8 MPa pressure regulating valve and the filter are connected to the uniform air circulation device, which is installed on both sides of the electromagnetic station wall. The stepless speed-regulating fan is installed on the electromagnetic station wall. The pressure transmitter is located at the air supply duct. The output of the pressure transmitter is connected to the controller's data receiving end. The controller's control end is connected to the start / stop devices of the DN20 electric valve and the stepless speed-regulating fan, respectively.

[0006] The beneficial effects of this utility model are as follows: After the wind pressure transmitter reaches the set value for 5 seconds, the controller opens the electric valve of the air supply pipeline. Dry and fresh air passes through the 0-08Mpa pressure regulating valve and filter 3 to remove dust from the air. After passing through the uniform air circulation devices installed on both sides of the electromagnetic station wall, the stepless speed-regulating fan installed on the electromagnetic station wall starts to discharge the high-temperature air of the electromagnetic station. This keeps the air entering the electromagnetic station equal to the air leaving the station, avoiding the formation of negative pressure in the sealed electromagnetic station. This solves the problems of frequent malfunctions and unusability of the air conditioner installed in the electromagnetic station's power distribution room due to dust, and the waste of energy and cost caused by the electromagnetic station's inability to dissipate heat and heavy-load shutdown.

[0010] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0011] like Figure 1 As shown, a dust removal and cooling system for an underground electromagnetic station is characterized by comprising a DN20 ball valve 1, a DN20 electric valve 2, a 0-0.8 MPa pressure regulating valve and a filter 3, a uniform air circulation device 4, a stepless speed-regulating fan 5, a pressure transmitter 6, and a controller 7. The DN20 ball valve 1 is installed on the fresh and clean air supply pipeline of the underground chamber. The downwind port of the DN20 ball valve 1 is connected to the DN20 electric valve 2. The downwind port of the DN20 electric valve 2 is connected to the 0-0.8 MPa pressure regulating valve and the filter 3. The 0-0.8 MPa pressure regulating valve and the filter 3 are connected to the uniform air circulation device 4, which is installed on both sides of the electromagnetic station wall. The stepless speed-regulating fan 5 is installed on the electromagnetic station wall. The pressure transmitter 6 is located at the air supply pipeline. The output end of the pressure transmitter 6 is connected to the data receiving end of the controller 7. The control end of the controller 7 is connected to the start / stop devices of the DN20 electric valve 2 and the stepless speed-regulating fan 5, respectively.

[0012] When this utility model is in use, after the underground conveyor belt system is running and the air pressure transmitter 6 reaches the set value for 5 seconds, the electric valve 2 of the air supply pipeline is opened. Dry and fresh air passes through the 0-08Mpa pressure regulating valve and filter 3 to remove dust from the air. After passing through the uniform air circulation device 4 installed on both sides of the electromagnetic station wall, the stepless speed-regulating fan 5 installed on the electromagnetic station wall starts after 5 seconds. Fresh air flows into the electromagnetic station and the stepless speed-regulating fan 5 removes the high-temperature air from the electromagnetic station, always keeping the air entering the electromagnetic station equal to the air leaving the electromagnetic station, and avoiding the formation of negative pressure in the sealed electromagnetic station.

[0013] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof.
