DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 , an assembled dust bag of the present embodiment comprises a dust bag 1, an induced draft fan 2 is fixed on the top of the dust bag 1, a dust inlet pipe 3 is fixedly connected to the top of the dust bag 1, one end of the dust inlet pipe 3 is fixedly connected to the dust inlet of the induced draft fan 2 and a connecting mechanism 4 connected to the exhaust end is arranged at the end of the dust inlet pipe 3, a dust outlet pipe 5 is fixedly connected to the lower side wall of the dust bag 1, and a cleaning mechanism 6 for cleaning the inner side wall of the dust bag 1 is arranged on the top of the dust bag 1; the cleaning mechanism 6 comprises a A fixed plate 601 is provided with an upper base 602, an electric push rod 603 is rotatably mounted on the upper base 602, the other end of the electric push rod 603 penetrates the dust bag 1 and is rotatably connected to the lower base 604, a round block 605 is fixed to the other end of the lower base 604, four cleaning rods 606 are fixed to the side of the round block 605, cleaning plates 607 are fixed to the ends of the four cleaning rods 606, and the four cleaning plates 607 are in contact with the side wall of the dust bag 1; the lower end of the inner side of the cleaning plate 607 is conical.

[0021] Specifically, by fixing the induced draft fan 2 at the top of the dust bag 1 and connecting it to the dust inlet pipe 3, the dust-containing gas can be introduced and extracted, the gas flow is promoted, and the dust removal efficiency is improved; a cleaning mechanism 6 is provided on the top of the dust bag 1, which is used to clean the inner wall of the dust bag 1, keep the dust bag 1 clean, and maintain the dust removal efficiency and service life.

[0022] Working principle: when the dust bag 1 needs to be used, first use the connecting mechanism 4 to connect the dust inlet pipe 3 with the exhaust end, and then turn on the induced draft fan 2 to introduce and extract the dust-containing gas, promote gas flow, and improve dust removal efficiency; when the inner wall of the dust bag 1 needs to be cleaned, the electric push rod 603 will be started, and the round block 605 will move on the top of the dust bag 1 through the rotation connection of the upper base 602 and the lower base 604. Four cleaning rods 606 are fixed on the side of the round block 605, and these cleaning rods 606 drive the cleaning plate 607 to move along the side wall of the dust bag 1; the inner lower end of the cleaning plate 607 is constructed in a conical shape. This design can effectively vibrate the dust in the dust bag 1, so that the dust adhering to the surface of the bag falls off; when the cleaning plate 607 contacts the side wall of the dust bag 1, due to the conical structure of the inner lower end of the cleaning plate 607, pressure can be generated to help the dust fall off and fall.

[0023] The bottom structure of the dust removal bag 1 is conical and fixedly connected with a threaded pipe 7, and the threaded pipe 7 is externally threadedly connected with a threaded sleeve 8; a plurality of filter cottons 9 are fixed inside the dust outlet pipe 5, and the working principle here is: since the bottom structure is conical and the threaded pipe 7 is fixed, this design is conducive to the concentration and discharge of dust; when the dust-laden gas enters the dust removal bag 1 and is filtered inside the filter bag, the dust will gradually settle on the conical structure at the bottom of the bag and be discharged through the threaded pipe 7; the threaded sleeve 8 is connected with the threaded pipe 7 externally, which ensures the sealing of the dust during discharge and avoids secondary diffusion of dust; a plurality of filter cottons 9 are fixed inside the dust outlet pipe 5, and these filter cottons 9 can further filter out the tiny particles and dust remaining in the gas to ensure that the discharged gas meets environmental protection standards.

[0024] The connecting mechanism 4 includes a ring 401 which is sleeved at the connection between the dust inlet pipe 3 and the exhaust end. One end of the ring 401 is open and a bolt 402 is threadedly connected to the opening. The other end of the bolt 402 is threadedly connected to a nut 403. The ring 401 which is sleeved at the connection between the dust inlet pipe 3 and the exhaust end plays a role of connection and fixation; one end of the ring 401 is open, which is convenient for installation and disassembly; one end of the bolt 402 is threadedly connected to the nut 403, and the other end is threadedly connected to the bolt 402 hole on the ring 401. By tightening the bolt 402 and the nut 403, the dust inlet pipe 3 and the exhaust end can be tightly connected and fixed together.
