[0002] With the continuous development of the times, bag filters, as a highly efficient gas-solid separation device, are widely used in industrial dust control. Their unique bag design allows operators to easily filter and collect attached materials, which is beneficial for secondary production and industrial purification. However, due to its design, replacing the filter bag will cause gas to leak into the atmosphere, which means that the machine must be stopped every time the bag filter is repaired or inspected, which seriously affects the production progress. In some production processes that are difficult to stop, it cannot be used at all. Therefore, a bag filter that can partially isolate exhaust gas emissions and form an independent space for easy maintenance is particularly important. Utility Model Content

[0003] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art and to provide a bag filter dust collector that is easy to maintain. Through a unique telescopic plate design, a grooved plate blocks the perforated plate when the filter bag is replaced, which effectively prevents gas leakage and allows maintenance to be carried out while the device is running, thus improving the stability and convenience of the bag filter dust collector.

[0004] This utility model also provides a baghouse dust collector with easy maintenance, comprising: a housing, a perforated plate fixedly connected to the upper surface of the housing, a purification box fixedly connected to the upper surface of the perforated plate, a storage box fixedly connected to the lower surface of the housing, and a telescopic plate fixedly connected to the upper surface of the perforated plate; a telescopic plate, a support frame fixedly connected to the lower surface of the telescopic plate, multiple telescopic rods fixedly connected to the upper surface of the support frame, cleaning rings fixedly connected to the side surfaces of the multiple telescopic rods, a grooved plate fixedly connected to the support frame, and a telescopic frame movably connected inside the grooved plate; a telescopic frame, a clamp fixedly connected to the upper surface of the telescopic frame, a telescopic rod fixedly connected to the lower surface of the clamp, a base frame fixedly connected to the lower surface of the telescopic rod, and a filter bag movably connected to the outer surface of the telescopic frame.

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figure 1-5This utility model provides a bag filter dust collector that is easy to maintain, comprising: a housing 3 for limiting the device; a perforated plate 17 fixedly connected to the upper surface of the housing 3, the perforated plate 17 for limiting the device and for accommodating the telescopic frame 2 after the filter bag 16 is placed on it; a purification chamber 5 fixedly connected to the upper surface of the perforated plate 17, the gas purified by the filter bag 16 enters the purification chamber 5 through the holes in the perforated plate 17; an exhaust pipe 12 fixedly connected to the side surface of the purification chamber 5, the exhaust pipe 12 penetrating into the purification chamber 5, the exhaust pipe 12 for discharging the gas inside the purification chamber 5; and a second motor 10 fixedly connected to the upper surface of the purification chamber 5. 0 provides the power source for the extension and retraction of the telescopic jet rod 8. The output end of the second motor 10 passes through the upper surface of the purification box 5 and is fixedly connected to the telescopic jet rod 8. When in use, the telescopic jet rod 8 is extended to pass through the perforated plate 17, and the jet spray causes the cloth bag 16 to vibrate and shake off the attached substances. A collection box 4 is fixedly connected to the lower surface of the box body 3. The collection box 4 is used to collect the fallen attached substances. A dust hopper 14 is fixedly connected to the lower surface of the box body 3. The dust hopper 14 is located inside the lower surface of the box body 3. Its inclined structure allows the clumps of attached substances that fall on it to fall into the collection box 4. The inner surface of the collection box 4 is fixedly connected to the lower surface of the dust hopper 14. A control plate 6 is fixedly connected at the intersection of the four sections. The control plate 6 is used to limit the device. A rotating shaft 15 is rotatably connected to the outer surface of the control plate 6. The rotating shaft 15 passes through the control plate 6 and the storage box 4, and runs horizontally through the interior of the storage box 4, allowing it to rotate freely. A rotating fan 7 is fixedly connected to the side surface of the rotating shaft 15. The rotating fan 7 is the same size as the channel from the ash hopper 14 to the storage box 4. When clumps of filter material fall onto the rotating fan 7, gravity will cause the rotating shaft 15 to rotate, causing it to fall into the storage box 4. At the same time, the rotating fan 7 also effectively prevents gas from entering the storage box 4. An air inlet pipe 11 is fixedly connected to the side surface of the box body 3. The gas to be filtered enters through the air inlet. Pipe 11 enters the box 3. The air inlet pipe 11 passes through the inside of the box 3 and is fixedly connected to a baffle 13. Large particles brought in by the air will hit the baffle 13 and fall directly into the storage box 4 to prevent the cloth bag 16 from being damaged. A telescopic plate 1 is fixedly connected to the upper surface of the perforated plate 17. The telescopic plate 1 is used to prevent the telescopic frame 2 from touching the cloth bag 16. At the same time, it can also block the perforated plate 17 to form a sealed space when changing the cloth bag 16. A No. 1 motor 9 is fixedly connected to the upper surface of the perforated plate 17. The No. 1 motor 9 provides the power source for the telescopic movement of the telescopic plate 1. The output end of the No. 1 motor 9 passes through the upper surface of the perforated plate 17 and is fixedly connected to the telescopic plate 1.

[0024] Telescopic plate 1 is used to limit the device. A support frame 103 is fixedly connected to the lower surface of telescopic plate 1. The support frame 103 is used to connect the multi-layer telescopic rods 101 and the grooved plate 104, so that the upper surface of the grooved plate 104 is higher than the lower surface of the multi-layer telescopic rods 101, which facilitates the grooved plate 104 to seal the perforated plate 17 after the multi-layer telescopic rods 101 are retracted. The multi-layer telescopic rods 101 are fixedly connected to the upper surface of the support frame 103. Through the design of the multi-layer telescopic rods 101, the multi-layer telescopic rods 101 inside the box 3 can be retracted to a shorter length, and most of them can be retracted into the upper surface of the perforated plate 17, which facilitates the grooved plate 104. The hole plate 17 is blocked. A cleaning ring 102 is fixedly connected to the side surface of the multi-layer telescopic rod 101. The cleaning ring 102 is located between the two telescopic parts. The inner surface has a cleaning brush, which can clean dust and debris during the retraction of the multi-layer telescopic rod 101 to prevent the multi-layer telescopic rod 101 from getting stuck. A grooved plate 104 is fixedly connected to the support frame 103. The grooved plate 104 is a flat plate with a groove. The inner groove fits perfectly with the telescopic frame 2 with the cloth bag 16 on it. It can be used to put into the telescopic frame 2. It can also be used to block the hole plate 17 when needed. The telescopic frame 2 is movably connected inside the grooved plate 104.

[0025] The telescopic frame 2 is used to limit the device. A clip 201 is fixedly connected to the upper surface of the telescopic frame 2. The clip 201 is used to press the edge of the cloth bag 16 to the upper surface of the perforated plate 17, which can prevent the telescopic frame 2 from falling and the cloth bag 16 from falling. A telescopic rod 202 is fixedly connected to the lower surface of the clip 201. The telescopic rod 202 can shorten the entire telescopic frame 2 when changing the cloth bag 16 in the limited space of the purification box 5, making it easier for the operator to change the cloth bag 16. A base frame 203 is fixedly connected to the lower surface of the telescopic rod 202. The base frame 203 is used to shape the cloth bag 16. The cloth bag 16 is movably connected to the outer surface of the telescopic frame 2. The cloth bag 16 is used to filter impurities in the gas.

[0026] Working principle: When the operator needs to inspect, maintain, or replace the filter bag 16, the purification box 5 can be opened first, the telescopic air jet rod 8 can be retracted, and the new filter bag 16 can be put onto the prepared telescopic frame 2. The first motor 9 can be started, and the multi-layer telescopic rod 101 can drive the groove plate 104 to bring the old telescopic frame 2 and filter bag 16 out of the box 3. At the same time, the groove plate 104 can block the hole plate 17 to prevent gas from entering the purification box 5. During the retraction of the multi-layer telescopic rod 101, the telescopic rod 202 can be used to shrink the space of the telescopic frame 2, making it easier to take out in the limited space. Similarly, the new telescopic frame 2 and filter bag 16 can be put into the groove of the groove plate 104 and placed into the box 3. Air can be blown into the box 3 through the air inlet pipe 11. After the dust and other impurities in the air are filtered onto the outer surface of the filter bag 16, the air blown by the telescopic air jet rod 8 can cause the filter bag 16 to vibrate, thereby shaking off the attached objects, which fall into the collection box 4 through the ash hopper 14.

[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
