[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Reference Figure 1 - Figure 6 , the utility model provides an embodiment: a line spray type bag dust collector, including a bag dust collector 1 and a water tank 6, a collecting bucket 2 is provided at the bottom of the bag dust collector 1, an air inlet pipe 4 is fixedly connected to one side of the bag dust collector 1, an air outlet pipe 5 is fixedly connected to the other side of the bag dust collector 1, a water inlet bucket 8 is fixedly connected to the middle side of the top of the water tank 6, a filter screen 7 is slidably connected to the inside of the water tank 6, two thin shells 9 are fixedly connected to the outside of the water tank 6, a thin shell 2 10 is fixedly connected to the top of the thin shell 10, a plug-in rod 12 is slidably connected to the inside of the thin shell 2 10, and one side of the plug-in rod 12 A baffle 13 is fixedly connected, a spring 14 is sleeved on the other side of the connecting rod 12, a blocking block 11 is provided on the top of the baffle 13, a water pipe 15 is fixedly connected to the outside of the water tank 6, a water pump 16 is provided on the outside of the water pipe 15, one end of the water pipe 15 is fixedly connected to a water spray joint 17, a fixed block 20 is fixedly connected to the top wall of the bag-type dust collector 1, a slider 18 is slidably connected to the inside of the bag-type dust collector 1, a connecting rod 19 is provided between the slider 18 and the water spray joint 17, and a reciprocating assembly is provided on the top of the bag-type dust collector 1, which is used to rotate the water spray joint 17.

[0034] Specifically, the bag filter 1 is a highly efficient air purification device for removing particulate matter in exhaust gas, such as dust, smoke and other pollutants. During use, the exhaust gas enters the bag filter 1 from the air inlet pipe 4. At this time, the water pump 16 starts, draws water from the water tank 6 and sprays it through the water pipe 15 and the water spray joint 17. The sprayed water mist comes into contact with the dust particles in the exhaust gas, causing some of the dust particles to dissolve or be wetted. Then, under the action of gravity, these dust-containing water droplets will move downward and eventually fall into the collection bucket 2, thereby entering the water tank 6. The water in the water tank 6 is preliminarily filtered through the filter screen 7 to remove larger suspended matter and impurities to ensure the quality of the recycled water. The filtered water is then pumped back by the water pump 16 and sprayed into the bag filter 1 again, realizing the recycling of wastewater and reducing the waste of water resources. When the filter 7 needs to be cleaned or replaced, by pulling the plug rod 12, the action will drive the baffle 13 to move outward, and at the same time the spring 14 will be compressed, and the blocking block 11 will slide from the thin shell 2 10 into the thin shell 1 9. This design cleverly prevents the plug rod 12 from returning to the filter 7 by itself due to the elastic force of the spring 14 after the hand is released, thereby facilitating the disassembly of the filter 7. After cleaning the filter 7, when reinstalling it, just pull the blocking block 11 upward. Under the elastic force of the spring 14, the baffle 13 and the plug rod 12 will move inward until they firmly penetrate the water tank 6 and are plugged into the inside of the filter 7, completing the installation of the filter 7. The whole process not only ensures the convenience of operation, but also ensures the normal operation of the system and the high-efficiency air purification effect.

[0035] Reference Figure 5 and Figure 6 The reciprocating assembly includes a support block 21, the bottom of the support block 21 is fixedly connected to the top of the bag dust collector 1, the outside of the support block 21 is fixedly connected to a motor 22, the output end of the motor 22 is fixedly connected to a turntable 23, the outside of the turntable 23 is fixedly connected to a connecting shaft 24, the outside of the connecting shaft 24 is slidably connected to a hollow shell 25, the bottom of the hollow shell 25 is fixedly connected to a moving rod 26, and the bottom end of the moving rod 26 is rotatably connected to the top right side of the water spray joint 17.

[0036] Specifically, during the operation of the bag filter 1, when the water spray connector 17 continuously sprays water, the system activates the drive motor 22. The operation of the drive motor 22 causes the turntable 23 and its connecting shaft 24 to rotate. Subsequently, the connecting shaft 24 slides back and forth within the hollow shell 25, causing the hollow shell 25 and the movable rod 26 to reciprocate up and down. This series of actions not only enables the water spray connector 17 to swing left and right, but also significantly widens the spray area of the water spray connector 17. The reciprocating swing of the water spray connector 17 provides more comprehensive coverage of the exhaust gas environment within the bag filter 1, ensuring that all dust particles in the exhaust gas have the opportunity to come into contact with the water mist. This helps the dust particles, due to the wetting effect of the water, become more easily adsorbed or settled, thereby improving the dust removal efficiency of the exhaust gas. In particular, when the water spray connector 17 continuously swings, it can more evenly distribute the water mist throughout the dust collector, ensuring the comprehensiveness and efficiency of the exhaust gas dust removal process.

[0037] Reference Figure 1 - Figure 6 The outside of the bag dust collector 1 is fixedly connected to two supporting legs 3, the outside of the baffle 13 is slidably connected to the inside of the thin shell 9, one end of the connecting rod 19 is rotatably connected to the inside of the slider 18, and the other end of the connecting rod 19 is rotatably connected to the top of the water spray joint 17, one end of the spring 14 is fixedly connected to one side of the baffle 13, and the other end of the spring 14 is fixedly connected to the inner wall of the thin shell 9, the upper side of the blocking block 11 is slidably connected to the inside of the thin shell 2 10, and the lower side of the blocking block 11 is slidably connected to the inside of the thin shell 9, the plug-in rod 12 passes through the water tank 6 and is plugged into the inside of the filter 7, and the upper part of the outer side of the water spray joint 17 is rotatably connected to the inside of the fixed block 20.

[0038] Specifically, the bag filter 1 is externally fixedly connected to two support legs 3 to provide stable support and ensure the stability of the equipment during operation. The baffle 13 is installed inside the thin shell 19 through a sliding connection on the outside, so that it can move on a specific path, which is convenient for the removal and installation of the filter 7. One end of the connecting rod 19 is rotatably connected to the inside of the slider 18, and the other end is connected to the top of the water spray joint 17, which plays the role of connecting and transmitting power, so that the water spray joint 17 can swing flexibly. One end of the spring 14 is fixed to one side of the baffle 13, and the other end is fixed to the inner wall of the thin shell 19. Through the elastic characteristics of the spring 14, a restoring force is provided for the movement of the baffle 13, ensuring that it can return to its original position after the operation is completed, and maintaining the normal operation of the equipment. The upper side of the blocking block 11 is slidably connected to the inside of the thin shell 2 10, and the lower side is slidably connected to the inside of the thin shell 19, forming a double-layer protection structure to prevent accidents during operation and ensure the safety of the equipment. The plug rod 12 passes through the water tank 6 and is inserted into the filter 7, which can be fixed and removed for easy cleaning and maintenance. The upper outer portion of the water spray joint 17 is rotatably connected to the inner side of the fixing block 20, allowing the water spray joint 17 to swing left and right when driven, expanding the water spray range and enhancing the dust removal effect.

[0039] Working principle: When the bag dust collector 1 is needed for dust removal, the exhaust gas enters the bag dust collector 1 from the air inlet pipe 4. At this time, the water pump 16 is started. The water pump 16 will spray the water from the water tank 6 through the water pipe 15 and the water spray joint 17, so that the dust in the exhaust gas will dissolve in water. Under the action of gravity, the dust particles contaminated with water will fall into the collection bucket 2 and flow into the water tank 6. The filter screen 7 can filter the water, and the filtered water can be sprayed into the bag dust collector 1 by the water pump 16, thereby realizing the recycling of waste water. When the filter screen 7 needs to be disassembled, pull the plug rod 12. This action will drive the baffle 13 to move outward, and at the same time the spring 14 will be compressed, and the blocking block 11 will slide from the inside of the thin shell 2 10 into the thin shell 1 9. This design prevents the plug-in rod 12 from re-entering the filter 7 under the elastic force of the spring 14 after the hand is released. At this time, the filter 7 is removed. When the clean filter 7 needs to be installed, it is only necessary to pull the blocking block 11 upward. At this time, under the elastic force of the spring 14, the baffle 13 and the plug-in rod 12 will move inward until they are firmly inserted into the water tank 6 and inserted into the filter 7. At this time, the installation is completed;

[0040] At this time, when the water spray joint 17 continuously sprays water, the drive motor 22 will be started, which will drive the turntable 23 and the connecting shaft 24 to rotate, so that the connecting shaft 24 will slide back and forth inside the hollow shell 25, thereby driving the hollow shell 25 and the moving rod 26 to move up and down, which will drive the water spray joint 17 to swing back and forth left and right, thereby expanding the spray range of the water spray joint 17, so that the dust in the exhaust gas in the bag dust collector 1 is contaminated with water, and the reciprocating swinging water spray joint 17 can improve the efficiency of exhaust gas dust removal.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
