Description

Technical Field

[0001] The utility model relates to the technical field of air filtering equipment, in particular to a filtering device for a drying tower heater. Background Art

[0002] The filter devices of the dry tower heater are usually designed to prevent solid particles or other impurities from entering the heater system, thereby protecting the normal operation of the heater and extending its service life. These filter devices are usually designed in the form of grids, screens or filters, which can filter out particulate matter in the air to keep the inside of the heater clean. These filter devices usually need to be cleaned or replaced regularly to ensure their filtering effect and the normal operation of the heater system.

[0003] The existing filtering device of the drying tower heater mainly starts from improving the permeability of the filter, and continuously upgrades the filter material, pore size, toughness, etc. to achieve better filtering effect.

[0043] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0044] See also Figure 1-Figure 6 , a filtering device for a drying tower heater, comprising an air duct 1, and further comprising:

[0047] The vibration device 2 comprises:

[0048] A plurality of brackets 21 are fixedly installed in a circular array on one side of the inner cavity of the air duct 1;

[0049] The protective cover 22 is fixedly mounted on the other end of the bracket 21 and is provided with an opening on the side away from the backflush device 3;

[0050] A vibration assembly 23, which is installed in the inner cavity of the protection cover 22;

[0051] The backflush device 3 comprises:

[0052] A rectifier assembly 31, which is installed on one side of the protective cover 22;

[0053] A hydraulic telescopic rod 32, which is installed on one side of the rectifier assembly 31;

[0054] The blowing assembly 33 is installed at the output end of the hydraulic telescopic rod 32 .

[0055] The filter screen 4 is fixedly installed on one side of the inner cavity of the air duct 1 , and a striker 5 is fixedly installed on the inner side of the filter screen 4 .

[0056] The vibration assembly 23 comprises:

[0057] A driving motor 231 is fixedly mounted in the inner cavity of the protective cover 22;

[0058] A connecting shaft 232, which is fixedly mounted on the output end of the driving motor 231 through a coupling;

[0059] A rotating shaft 233, which is rotatably connected to the other end of the connecting shaft 232;

[0060] A slide bar 234, which is fixedly mounted in the inner cavity of the protection cover 22;

[0061] A sliding member 235, which is slidably connected to the outer side of the sliding rod 234, and one side of which is rotatably connected to the other end of the rotating shaft 233;

[0062] The impact member 236 is fixedly mounted on the other side of the sliding member 235 , and the impact member 236 can pass through the opening on one side of the protection cover 22 .

[0063] Specific implementation method: The accelerated high-speed airflow flows into the air duct 1, and is blocked and filtered by the filter 4, and foreign matter is blocked on one side of the filter 4. The filter 4 is annular, and its inner side is fixedly connected to the outer side of the impact member 5. The impact member 5 and the filter 4 are both made of soft materials and can undergo certain deformation;

[0064] After working for a period of time, the user stops the high-speed airflow from entering and starts the driving motor 1 231. The driving motor 1 231 drives the connecting shaft 232 to rotate through the coupling, driving the rotating shaft 233 to perform horizontal displacement and angular rotation, thereby driving the sliding member 235 to slide along the sliding rod 234, and the impact member 236 fixedly installed on one side of the sliding member 235 performs reciprocating horizontal motion. The impact member 236 continuously hits the receiving member 5, and the shaking and deformation of the receiving member 5 drive the filter screen 4 to shake and deform, and the foreign matter attached to one side of the filter screen 4 is shaken off;

[0065] The driving motor 231 is electrically connected to an external power source and is also controlled by an external PLC programming program. The protective cover 22 supports and protects the vibration component 23, and the bracket 21 supports and fixes the connection.

[0066] The rectifier assembly 31 includes:

[0067] The fairing 311 is fixedly mounted on the side of the protective cover 22 away from the filter 4, the inner wall of the fairing 311 is fixedly connected to one side of the hydraulic telescopic rod 32, and an opening is provided on the side away from the filter 4;

[0068] A plurality of wind resistance plates 312 are fixedly installed on the outside of the fairing 311 in a circular array, and the other ends of the wind resistance plates 312 are fixedly connected to the inner wall of the air duct 1 respectively.

[0069] The blowing assembly 33 comprises:

[0070] A second driving motor 331 is fixedly mounted on the output end of the hydraulic telescopic rod 32;

[0071] The rotating shaft 332 is fixedly mounted on the output end of the second driving motor 331 through a coupling, and can pass through the opening on one side of the fairing 311;

[0072] A plurality of blades 333 are fixedly mounted on the outside of the rotating shaft 332 in a circular array and are all located outside the fairing 311 .

[0073] The limit electromagnet 6 is fixedly mounted on the wind resistance plate 312 close to the fan blade 333 .

[0074] Specific implementation method: while the vibration device 2 is working, the user starts the hydraulic telescopic rod 32, the hydraulic telescopic rod 32 is extended to move the blowing assembly 33 for a distance, and the driving motor 331 is started. The driving motor 331 drives the rotating shaft 332 and the fan blades 333 to rotate through the coupling, and blows air in the direction opposite to the high-speed airflow to blow away the foreign matter that has been shaken off or not for subsequent processing. Since the air on the side of the air duct 1 close to the back-blowing device 3 has been filtered, the back-blowing airflow is clean and no foreign matter will be left on the side of the filter 4 close to the back-blowing device 3;

[0075] When back-blowing is stopped, the user turns off the second driving motor 331, and after the fan blade 333 stops moving, the limit electromagnet 6 is started. Under the attraction of the limit electromagnet 6, the fan blade 333 moves to one side of the wind resistance plate 312, and the limit electromagnet 6 is turned off. The wind resistance plate 312 is semicircular, and the concave side is close to the limit electromagnet 6. At this time, the hydraulic telescopic rod 32 is shortened, driving the blowing component 33 to approach the wind resistance plate 312, and the fan blade 333 is close to the wind resistance plate 312. After the high-speed airflow passes through, the wind resistance plate 312 can play a supporting, wind-breaking and flow-guiding role to prevent the high-speed airflow from damaging the fan blade 333, and the fairing 311 plays a supporting and rectifying role;

[0076] The hydraulic telescopic rod 32 is controlled by an external PLC programming program, and the second driving motor 331 and the limit electromagnet 6 are electrically connected to an external power supply, and are also controlled by an external PLC programming program.

[0077] Working principle: After the airflow is accelerated, the high-speed airflow passes through the filter 4 and the air duct 1, and the foreign matter is blocked and filtered on one side of the filter 4. After working for a period of time, the user stops the entry of the high-speed airflow as appropriate, and uses the vibration device 2 to continuously impact the impact member 5, driving the filter 4 to vibrate and shake off the foreign matter. At the same time, the foreign matter that has not been shaken off and the foreign matter that has been shaken off are blown away with the help of the back-blowing device 3 for subsequent processing. After the cleaning is completed, the fan blade 333 is protected with the help of the wind resistance plate 312 to prevent it from being damaged by the high-speed airflow.

[0078] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
