Each second stop bar is fixedly disposed on the upper side of the second mounting hole 1084, and the second stop bar abuts against the upper side of the second double-layer membrane 120, and the second stop bar enables the second double-layer membrane 120 to be recessed only toward the inside of the second filter cartridge 108.
In this embodiment, the dust removing device for a feed conveying device further includes an air pump 101 and a communicating pipe 103, one end of the communicating pipe 103 is communicated with the upper end of the hollow tube 106, the air pump 101 is fixedly arranged on the housing 109, the air pump 101 is communicated with the other end of the communicating pipe 103, and the communicating pipe 103 is provided with an air outlet 102 for exhausting air. The air pump 101 is started, dust-containing gas enters from the air inlet 1092 and passes through the first filter screen 1051, clean gas filtered by the first filter screen 1051 enters into the first filter cartridge 105, then the clean gas sequentially passes through the second through groove 1054 and the first through groove 1062, enters into the hollow cylinder 106, and enters into the communicating pipe 103 from the upper end of the hollow cylinder 106, and finally the clean gas is discharged from the air outlet 102.
Through setting up air pump 101, during the air pump 101 work, because first filter screen 1051 receives the effect of air current, so first cartridge filter 105 and second cartridge filter 108 can wholly rotate, do not need peripheral hardware drive arrangement and controlling means, save manufacturing cost.
In this embodiment, a connection disc is fixedly provided at the lower end of the hollow cylinder 106, the connection disc and the hollow cylinder 106 are concentrically provided, a second annular groove 1064 is provided on the connection disc, and the second annular groove 1064 extends along the circumferential direction of the hollow cylinder 106. A ring block 1081 is provided on the lower end surface of the second filter cartridge 108, the ring block 1081 being rotatably disposed within the second ring groove 1064 such that the second filter cartridge 108 rotates relative to the hollow cylinder 106.
In this embodiment, a stopper is fixedly disposed on the lower end surface of the connection pad, a square hole 1091 is formed in the bottom of the housing 109, the stopper is disposed in the square hole 1091, and when the first filter cartridge 105 and the second filter cartridge 108 rotate, the hollow cylinder 106 does not rotate, and the hollow cylinder 106 is also convenient for subsequent disassembly and assembly.
In this embodiment, a cover plate 104 is fixedly disposed at the upper end of the housing 109, a central hole 1041 is formed in the middle of the cover plate 104, and the upper end of the hollow tube 106 penetrates through the central hole 1041.
The working process comprises the following steps: in the initial state, one of the first filtering passages 1053 communicates with the air inlet 1092, and the second through-passage 1054 communicates with the first through-passage 1062.
The air pump 101 is started, dust-containing gas enters from the air inlet 1092 and passes through the first filter screen 1051, clean gas filtered by the first filter screen 1051 enters into the first filter cartridge 105, then the clean gas sequentially passes through the second through groove 1054 and the first through groove 1062, enters into the hollow cylinder 106, and enters into the communicating pipe 103 from the upper end of the hollow cylinder 106, and finally the clean gas is discharged from the air outlet 102.
Because the first filter screen 1051 is acted by the airflow, the first filter cartridge 105 and the second filter cartridge 108 rotate integrally, when the first filter channel 1053 rotates until the first filter channel 1053 and the air inlet 1092 are completely staggered, the second filter channel 1082 is communicated with the air inlet 1092, the third through-channel 1085 is communicated with the first through-channel 1062, the second filter screen 1083 starts to work, the dust-containing gas passes through the second filter screen 1083 from the air inlet 1092, the clean gas filtered by the second filter screen 1083 enters the second filter cartridge 108, then the clean gas sequentially passes through the third through-channel 1085 and the first through-channel 1062 and then enters the hollow tube 106, and finally the clean gas enters the communication tube 103 from the upper end of the hollow tube 106, and is discharged from the air outlet 102.
When clean gas enters the hollow cylinder 106 from the second filter cartridge 108, because the gas passes through the second filter cartridge 108, the pressure in the second filter cartridge 108 is smaller than the pressure in the first filter cartridge 105, and the second double-layer membrane 120 on the second filter cartridge 108 is recessed toward the inside of the second filter cartridge 108, so that the space at the first filter channel 1053 is enlarged, and the gas passes from the first filter cartridge 105 to the first filter channel 1053 through the first filter screen 1051, so that dust left by the first filter screen 1051 in the previous working process is blown back.
When the first filter cartridge 105 and the second filter cartridge 108 are rotated faster due to the greater amount of dust and thus the first filter cartridge 1051 or the second filter cartridge 1083 is blocked seriously during an operation, the first filter cartridge 105 drives the rotation ring 107 to rotate synchronously through the compression spring 200, and the more the compression spring 200 is compressed, the more the air pressure push plate 201 moves toward the first end of the swivel air chamber 1071, and the space between the air pressure push plate 201 and the second end of the swivel air chamber 1071 is larger. At this time, the gas in the first gas chamber 1101 and the second cavity goes into the swivel gas chamber 1071 through the Y-shaped hose, so that the first gas chamber 1101 and the second cavity become smaller, and further, when the first filter screen 1051 or the second filter screen 1083 starts to be cleaned, more gas can enter the first filter channel 1053 or the second filter channel 1082, and the greater the backflushing degree, the more thoroughly the backflushing.
When the first filter screen 1051 or the second filter screen 1083 is not seriously blocked, the less the air pressure push plate 201 moves towards the first end of the swivel air cavity 1071, the smaller the space between the air pressure push plate 201 and the second end of the swivel air cavity 1071 is, the larger the first air cavity 1101 and the second cavity are, so that when the first filter screen 1051 or the second filter screen 1083 starts to be cleaned, the gas entering the first filter channel 1053 or the second filter channel 1082 is reduced, the smaller the backflushing degree is, and dust flow disturbance caused by overlarge backflushing gas flow rate is prevented.
In other embodiments of a dust removing device for a feed conveying device of the present invention, different from the above-described embodiments, it is: the pressure spring 200 in the connecting assembly can also be replaced by an electric control hydraulic rod, one end of the electric control hydraulic rod is fixedly connected with the first end of the swivel air cavity 1071, and the other end of the electric control hydraulic rod is fixedly connected with the air pressure push plate 201.
The adjusting mechanism further comprises a sensor and a plurality of controllers, wherein the sensor is arranged on the first filter cylinder 105 and used for detecting the rotation speed of the first filter cylinder 105, and each controller is arranged on one electric control hydraulic rod and used for controlling the extension and shortening of the extension end of the electric control hydraulic rod. When the first filter cartridge 105 and the second filter cartridge 108 are blocked more seriously, the first filter cartridge 105 rotates faster, and the sensor senses that the rotation speed of the first filter cartridge 105 becomes faster, the controller shortens the extension end of the electric control hydraulic rod, so that the air pressure push plate 201 moves towards the first end of the swivel air chamber 1071, and the space between the air pressure push plate 201 and the second end of the swivel air chamber 1071 becomes larger.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
