Description

Technical Field

[0001] This utility model belongs to the technical field of blower devices, specifically a blower device for a vertical furnace press. Background Technology

[0002] A vertical shaft furnace is an ultra-high power electric arc furnace with an upright furnace body and a vertical shaft on the furnace cover. It uses the high-temperature exhaust gas from the electric arc furnace to preheat the scrap steel in the vertical shaft. The furnace gas moves upward in the furnace and exchanges heat with the furnace charge in a countercurrent manner. In most vertical shaft furnaces, the furnace charge and fuel are in direct contact.

[0003] Generally, a blower is installed on the vertical shaft furnace press to stabilize the furnace temperature, mix combustion, and remove harmful gases.

[0004] There is a lot of dust in the working environment of the vertical furnace. When the fan device of the vertical furnace press is in use, the fan device does not have the function of dust filtration. The dust in the air transported by the fan may affect the normal operation of the parts of the vertical furnace press. Therefore, a fan device for the vertical furnace press is proposed to address the above problems. Utility Model Content

[0013] This utility model provides a blower device for a vertical furnace press. By setting a dustproof perforated plate on the air intake chamber shell, the dust in the air is initially filtered. Through the structural setting of the dust filtration mechanism, the air flowing through the dust filtration shell is treated for dust filtration.

[0014] This utility model provides a blower device for a vertical shaft furnace press. It involves mounting steel filter screens on multiple brackets inside a dust filter housing and installing a shell plate at the bottom of the housing. Multiple dust collection boxes are positioned on either side of the steel filter screens. Air flows sequentially through the steel filter screens, whose pore sizes gradually decrease, thus filtering the air.

An electrostatic adsorption layer in the dust collection box absorbs the falling dust, facilitating subsequent cleaning by the user. Attached Figure Description

An impeller main shaft 3 is provided inside the impeller cavity, and a blower impeller 4 is provided on the impeller main shaft 3. The blades of the blower impeller 4 are curved. A blower upper shell 5 is provided above the housing 2. The blower upper shell 5 and the housing 2 are integrally formed. A flow channel 6 is provided at the connection between the blower upper shell 5 and the housing 2. The flow channel 6 is used to deliver the air generated by the rotation of the blower impeller 4 to the blower upper shell 5. A flange support frame 7 is provided in front of the blower upper shell 5. A dust filter mechanism is detachably provided on the flange support frame 7. The dust filter mechanism filters the dust in the air transported by the blower device. A motor 8 is provided on the workbench 1. The output end of the motor 8 is connected to the impeller main shaft 3 through a coupling. The operation of the motor 8 rotates the impeller main shaft 3, so that the blower impeller 4 generates high-speed air in the impeller cavity.

[0027] Furthermore, such as Figure 1 As shown, an air intake chamber shell 9 is detachably installed on the front side of the impeller chamber, and a dustproof perforated plate 10 is detachably installed on the air intake chamber shell 9. The air intake chamber shell 9 facilitates the introduction of outside air into the impeller chamber. The dustproof perforated plate 10 is made of high-quality steel, and the dust in the air is initially filtered through the holes on the dustproof perforated plate 10.

[0028] Furthermore, such as Figure 3 and Figure 5As shown, the dust filtration mechanism includes a mounting frame 11 detachably mounted to the flange support frame 7. A dust filter shell 12 is mounted on the mounting frame 11. Multiple sets of mounting brackets 13 are evenly arranged inside the dust filter shell 12. Steel filter screens 14 are detachably mounted on the multiple sets of mounting brackets 13. Multiple connecting lines 15 are arranged on the upper inner side of the dust filter shell 12. A weight ball 16 is mounted on the connecting line 15. The multiple weight balls 16 are located between the steel filter screens 14. A shell plate 17 is detachably mounted on the bottom of the dust filter shell 12. Multiple dust collection boxes 18 are mounted on the shell plate 17. Through the structural arrangement of the dust filtration mechanism, the dust in the air conveyed by the fan device is treated by dust removal.

[0029] Furthermore, such as Figure 3 and Figure 5 As shown, multiple dust collection boxes 18 are located on both sides of multiple steel filter screens 14. An electrostatic adsorption layer 19 is detachably provided on the inner side of the dust collection box 18, which is used to collect the dust shaken off from the steel filter screens 14 into the dust collection box 18.

[0030] Furthermore, such as Figure 5 As shown, the aperture of multiple steel filter screens 14 located away from the mounting frame 11 decreases sequentially, which can perform multi-stage filtration of dust in the air.

[0031] Furthermore, such as Figure 1 and Figure 3 As shown, the flange support frame 7 is provided with multiple positioning holes 20 and insert blocks 21, and the mounting support frame 11 is provided with multiple mounting holes 22 and slots 23 evenly distributed. The corresponding positioning holes 20 and mounting holes 22 are connected by bolts, and the insert blocks 21 and slots 23 are inserted into each other, which improves the stability of the flange support frame 7 and the mounting support frame 11, thereby improving the stability of the dust filter housing 12 on the upper shell 5 of the fan.

[0032] Working principle: The user installs and fixes the vertical furnace press with a blower device, then connects the flange support frame 7 to the mounting support frame 11. The corresponding positioning holes 20 and mounting holes 22 are connected by bolts. The insert block 21 and the slot 23 are inserted into each other, thereby installing the dust filter shell 12 on the blower upper shell 5. Through the operation of the motor 8, the impeller main shaft 3 is rotated, so that the blower impeller 4 generates high-speed air in the impeller cavity. The air flows into the blower upper shell 5 through the diversion groove 6.

[0033] By installing a dustproof perforated plate 10 on the air intake chamber shell 9, the dust in the air is initially filtered.

[0034] Through the structural design of the dust filtration mechanism, the air flowing through the dust filter housing 12 is filtered. Multiple mounting brackets 13 inside the dust filter housing 12 are fitted with steel filter screens 14, and a shell plate 17 is installed at the bottom of the dust filter housing 12. Multiple dust collection boxes 18 are located on both sides of the multiple steel filter screens 14. Air flows sequentially through the steel filter screens 14, whose pore sizes gradually decrease, thus filtering the air. As the air flows sequentially through the steel filter screens 14, the flowing air continuously blows the drop balls 16 on the connecting line 15, causing the drop balls 16 to continuously strike the steel filter screens 14, causing the dust on the steel filter screens 14 to fall off. The electrostatic adsorption layer 19 set in the dust collection box 18 adsorbs the falling dust into the dust collection box 18, facilitating later cleaning by the user.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
