[0018] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0019] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a single-unit bag filter dust collector, including a housing 1, a collecting head 2, a discharge pipe 3, and an air inlet pipe 4. The collecting head 2 is located at the bottom of the housing 1, and the bottom of the collecting head 2 is connected to the discharge pipe 3. The air inlet pipe 4 is located on the right side of the housing 1. A first fixing plate 5 is fixedly connected to the upper part of the interior of the housing 1. A fixing mechanism is located on the top of the first fixing plate 5, and multiple filter bags 6 are installed on the first fixing plate 5 through the fixing mechanism. An air extraction mechanism is located on the front of the housing 1, and a reverse blowing mechanism is located on the upper right side of the housing 1. The housing 1 and the collecting head 2 are configured... The structure is split and can be detached by mounting bolts. When replacing the filter bag 6, the collecting head 2 can be removed from the bottom of the box 1, allowing the employee to enter the inside of the box 1. The dust-laden gas is drawn into the inside of the box 1 by the suction mechanism. Multiple filter bags 6 are installed inside the box 1 by a fixing mechanism. The filter bags 6 can separate the dust from the gas. Then the gas is discharged from the box 1, and the dust is trapped on the surface of the filter bags 6. The reverse blowing mechanism can blow the filter bags 6 to swell, shaking the dust on the surface of the filter bags 6 into the collecting head 2. The dust slides down the inclined inner wall of the collecting head 2 and slides to the outside through the discharge pipe 3.

[0020] The fixing mechanism includes a movable plate 7, a second fixing plate 8, fastening bolts 10, connecting blocks 11, and a slotted groove 12. Multiple movable plates 7 are fixedly connected to the top of the first fixing plate 5. A second fixing plate 8 is located on one side of the movable plate 7. Multiple fastening bolts 10 are fixedly connected to the top of the movable plate 7. Multiple connecting blocks 11 are fixedly connected to the top of the second fixing plate 8. A slotted groove 12 is provided inside each connecting block 11. The top of each fastening bolt 10 extends through the slotted groove 12 and is threaded with a nut. The air outlet pipe 20 of the bag 6 is inserted from bottom to top into the first fixing plate 5 along the inner wall of the fixing hole 9 on the movable plate 7. Then, the second fixing plate 8 is placed... The connecting block 11 is positioned on one side of the movable plate 7, and the fixing hole 9 inside the second fixing plate 8 is also attached to the outside of the air outlet pipe 20. At the same time, the top of the fastening bolt 10 passes through the strip groove 12 inside the connecting block 11. The nut is tightened on the top of the fastening bolt 10, and the connecting block 11 is clamped to the movable plate 7 by the nut, so as to connect the movable plate 7 and the second fixing plate 8 into one unit. The movable plate 7 and the second fixing plate 8 also clamp multiple air outlet pipes 20 at the same time, so as to fix multiple filter bags 6 at the bottom of the first fixing plate 5. When disassembling, simply loosen the nut and pull the movable plate 7 and the second fixing plate 8 to separate them from each other, so as to solve the problem of replacing filter bags one by one, which is cumbersome and time-consuming.

[0021] The movable plate 7 has symmetrical connecting bolts at both ends. The two ends of the movable plate 7 are detachably connected to the two sides of the top of the box 1 through the connecting bolts. The movable plate 7 and the second fixing plate 8 have multiple fixing holes 9 inside. The movable plate 7 is connected to the upper part of the box 1 through the connecting bolts, which can increase the support capacity of the movable plate 7 for the cloth bag 6, making the position of the cloth bag 6 inside the box 1 more stable.

[0022] The top of the first fixing plate 5 is fixedly connected to an air outlet pipe 20, the top of which extends through the interior of the first fixing plate 5. The inside of the cloth bag 6 is provided with cage bones.

[0023] The air extraction mechanism includes a fan 13, an exhaust pipe 14, and an air supply pipe 15. The fan 13 is located on the lower front of the housing 1. The output end of the fan 13 is connected to the exhaust pipe 14, and the input end of the fan 13 is connected to the air supply pipe 15. The top end of the air supply pipe 15 is connected to the top of the first fixed plate 5. The fan 13 draws air from the inside of the housing 1 through the air supply pipe 15 and then discharges it to the outside through the exhaust pipe 14, making the inside of the housing 1 a negative pressure state. When the ash conveying pipe is connected to the air inlet pipe 4, the pressure difference is used to attract dust-laden gas into the inside of the housing 1. When the dust-laden gas comes into contact with the filter bag 6, it will separate the gas from the dust. The dust is trapped on the surface of the filter bag 6, while the gas enters the inside of the filter bag 6 and flows along the exhaust pipe 20 to the top of the first fixed plate 5. The fan 13 and the air supply pipe 15 transport it to the inside of the exhaust pipe 14 and discharge it to the outside through the exhaust pipe 14.

[0024] The backflushing mechanism includes an air tank 16, an air pipe 17, and a pulse valve 18. An air tank 16 is fixedly installed on the top right side of the housing 1. One end of the air tank 16 is connected in series with the top of each filter bag 6 through a branch pipe, and a pulse valve 18 is installed on each branch pipe. The other end of the air tank 16 is connected to the top of the air supply pipe 15 through the air pipe 17. When the pressure on the filter bag 6 reaches the preset pressure value, the pressure detector on the filter bag 6 sends an electrical signal to the pulse valve 18. The pulse valve 18 receives the electrical signal and is energized, opening a small channel. The gas in the air tank 16 quickly passes through the outlet of the pulse valve 18, forming a high-pressure airflow, which is delivered to the inside of the filter bag 6 through the branch pipe. The filter bag 6 quickly inflates, shaking off the dust on the outside, thus realizing the dust cleaning operation of the filter bag 6.

[0025] The bottom end of the discharge pipe 3 is detachably connected to an ash discharge valve via assembly bolts. The ash discharge valve includes a housing, a motor, and an impeller. The housing is fixedly installed at the bottom end of the discharge pipe 3. An impeller is rotatably connected inside the housing. A motor is fixedly installed at one end of the housing. The output end of the motor passes through the interior of the housing and is fixedly connected to one end of the impeller. The motor can drive the impeller to rotate inside the housing. When dust falls into the interior of the housing, due to the tight fit between the impeller and the housing and the effect of the sealing device, a relatively stable pressure difference can be maintained during the unloading process, so that the material or dust can only be discharged in an orderly manner according to the set path, realizing continuous and quantitative ash discharge operation.

[0026] In this single-unit bag filter dust collector, the air outlet pipe 20 of the top of the filter bag 6 is inserted from bottom to top into the interior of the first fixing plate 5 along the inner wall of the fixing hole 9 on the movable plate 7. Then, the second fixing plate 8 is placed on one side of the movable plate 7, and the fixing hole 9 inside the second fixing plate 8 is also attached to the outside of the air outlet pipe 20. At the same time, the top of the fastening bolt 10 passes through the strip groove 12 inside the connecting block 11. The nut is tightened on the top of the fastening bolt 10, and the connecting block 11 and the movable plate 7 are clamped by the nut, so as to connect the movable plate 7 and the second fixing plate 8 into one unit. The movable plate 7 and the second fixing plate 8 also clamp multiple air outlet pipes 20 at the same time, so as to fix multiple filter bags 6 at the bottom of the first fixing plate 5. When disassembling, simply loosen the nut and pull the movable plate 7 and the second fixing plate 8 to separate them, so as to solve the problem of replacing filter bags one by one, which is cumbersome and time-consuming.
