DETAILED DESCRIPTION

In other words, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0019] like Figure 1-5 The vertical air inlet bag dust collector shown is easy to install, comprising a lower shell 13, an upper shell 14 and a hopper 16 arranged at the bottom of the lower shell 13. An air outlet 18 is opened on one side of the upper shell 14. The upper shell 14 and the lower shell 13 are fixed by bolts. A baffle 19 is provided around the top of the lower shell 13. Four rectangular orifice plates 1 arranged counterclockwise and fixed by bolts are placed on the baffle 19. The long side of the rectangular orifice plate 1 is the first side 2, the short side is the second side 3, and the side of the first side 2 is fixed by bolts. A lower limit strip 4 is provided on the top, and an upper limit strip 5 is provided at the joint of the second side 3 and the lower limit strip 4. A number of first bolt holes 6 are provided at the corresponding positions of the lower limit strip 4 and the upper limit strip 5. A number of detachable dust bags 8 are provided below the rectangular orifice plate 1. A hole 10 is formed in the middle of the rectangular orifice plate 1. A detachable vertical air inlet pipe 11 is provided in the hole 10. An inverted tower-shaped deflector 15 is connected to the bottom of the vertical air inlet pipe 11, and a dust outlet 23 with a gradually decreasing inner diameter is provided in the center of the inverted tower-shaped deflector 15.

[0020] The top surface of the inverted tower-shaped baffle 15 is provided with a plurality of guide grooves 17 . When in use, the dust-laden gas is dispersed to the surroundings through the guide grooves 17 , thereby effectively improving the dust removal efficiency.

[0021] The rectangular orifice plate 1 is provided with a plurality of threaded holes 7 , and the dust bag 8 is provided with a bag frame used in conjunction with the threaded holes 7 . During installation, the dust bag 8 is conveniently installed through threaded connection.

[0022] An L-shaped clip 9 is fixedly connected to one side of the upper and lower limit strips 4 of the first side 2. The L-shaped clips 9 constitute the four sides of the hole 10. An inverted L-shaped slot 12 for use with the L-shaped clip 9 is provided around the vertical air inlet pipe 11. A connecting plate 20 is also provided at the joint above the first side 2 and the vertical air inlet pipe 11. A plurality of second bolt holes are opened on the connecting plate 20. During installation, preliminary positioning is performed through the L-shaped clip 9 and the inverted L-shaped slot 12, and then the bolts are screwed into the second bolt holes to further strengthen the connection strength between the rectangular hole plate 1 and the vertical air inlet pipe 11.

[0023] A back-blowing pipe 21 is provided inside the upper shell 14 and above the dust bag 8. The back-blowing pipe 21 is connected to an external pulse back-blowing device. A plurality of air blowing ports 22 are provided below the back-blowing pipe 21. The air blowing ports 22 correspond to the positions of the dust bag 8. When in use, the pulse back-blowing device blows air into the dust bag 8 at a fixed frequency to clean the surface of the dust bag 8. Specific embodiments

[0024] During installation, first fit the rectangular orifice plate 1 against each other in a counterclockwise direction, fit the lower limit bar 4 with the upper limit bar 5, and screw the bolt into the first bolt hole 6 to fix it, then put the rectangular orifice plate 1 from top to bottom on the outside of the vertical air inlet pipe 11 until the L-shaped buckle 9 fits with the inverted L-shaped slot 12, screw the bolt into the second bolt hole to further strengthen the connection strength between the rectangular orifice plate 1 and the vertical air inlet pipe 11, then place the rectangular orifice plate 1 on the baffle 19 in the lower shell 13 and fix it with bolts, finally cover the upper shell 14 and tighten the bolts to complete the closure. During use, dust-laden gas enters from the vertical air inlet pipe 11, and a part of the large dust particles will be directly discharged downward from the dust removal port 23 into the hopper 16 under the influence of its own weight or wind force. The other dust-laden gas will be evenly dispersed to the surroundings under the action of the inverted tower-shaped baffle 15 and the guide groove 17. The dust will be adsorbed on the surface of the dust bag 8. The dust-removed gas will move upward through the threaded hole 7 to the upper shell 14 and be discharged through the air outlet 18. The pulse back-blowing device will regularly back-blow air into the dust bag 8 to regularly clean the dust attached to the surface of the dust bag 8.

[0025] This design is ingenious. The upper and lower limit bars are used for easy positioning and installation. The dust bag under the orifice plate is detachable and easy to install. In addition, the inverted tower-shaped baffle and guide groove can make the dust-laden gas disperse evenly to the surroundings, thereby improving the dust removal efficiency. When the dust-laden gas enters the dust collector, a part of the dust will fall directly into the hopper from the dust outlet, slowing down the attachment rate of the dust on the surface of the dust bag. The pulse backflush device can regularly clean the dust attached to the surface of the dust-laden gas, thereby effectively increasing the service life of the dust bag.

[0026] The present invention is not limited to the aforementioned specific embodiments, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
