[0004] In the above scheme, the dust adhering to the inner wall of the cloth bag dust collector body is cleaned by the rotation of the cleaning brush in the cleaning device, which has the following disadvantages: the position of the connecting rod and the cleaning brush is fixed during use, and cannot be adjusted according to the internal size of cloth bag dust collectors of different sizes, which reduces the flexibility and practicality of the device. UTILITY MODEL CONTENTS

[0005] The utility model aims to provide a cloth bag dust collector for waste liquid incineration, to solve the problem that the position of the connecting rod and the cleaning brush is fixed during use, and cannot be adjusted according to the internal size of cloth bag dust collectors of different sizes, which reduces the flexibility and practicality of the device.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a bag filter for waste liquid incineration, comprising a dust inlet pipe, the dust inlet pipe being connected and fixed to the left side of the outer wall of the bag filter body, a dust outlet funnel being fixed to the bottom surface of the bag filter body, a top cover being bolted to the top surface of the bag filter body, a fan being provided on the right side of the outer wall of the bag filter body, a guide pipe being fixedly connected between the fan and the bag filter body, a drive motor being fixed to the inner top surface of the top cover, a rotating shaft being fixed to the output shaft of the drive motor, connecting rods being fixed to the left and right sides of the rotating shaft, the connecting rods being hollow structures, connecting posts being slidably inserted into the interior of the two connecting rods, cleaning brushes being fixed to the outer ends of the two connecting posts, a plurality of first threaded grooves being opened on the top surface of the two connecting posts, a first threaded hole being opened on the top surface of the two connecting rods, a first bolt body being threadedly connected to the two first threaded holes, and the threaded end of the first bolt body being threadedly connected to the interior of the first threaded groove.

[0014] II. During operation, when the fan is turned on, dust-laden gas enters the baghouse dust collector. Large particles in the gas fall off under gravity, while small particles are adsorbed by the filter bags. To maintain the cleanliness of the filter bags and dust removal efficiency, the pulse valve needs to be opened periodically. After the pulse valve is opened, the gas inside the air tank is blown towards the filter bags through the venturi tube and nozzles. This pulse-type jetting method causes the dust adsorbed on the outer wall of the filter bags to fall off from the dust outlet funnel under the action of the wind, thus maintaining the cleanliness of the filter bags and dust removal efficiency. An installation hole is provided on the top surface of the air duct, and a filter screen is detachably installed in it. When the purified gas is discharged through the air duct, the filter screen can further filter out tiny impurities in the gas, preventing them from entering the fan and causing damage.

[0015] III. During use, the filter screen is connected to the air duct via a fixing plate and the second bolt body. Operators can easily remove the filter screen from the air duct for cleaning or replacement simply by loosening the second bolt body. A sealing ring is fixed to the bottom surface of the fixing plate. When the filter screen is installed on the air duct, the sealing ring fits tightly against the top surface of the air duct, preventing gas leakage from the mounting holes. A collection box is located at the bottom of the dust discharge funnel. When large particles of impurities fall from the dust discharge funnel, they are collected in the collection box. Operators can periodically clean the impurities in the collection box to ensure the normal operation of the bag filter dust collector. Attached Figure Description

Detailed Implementation

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1-4 As shown, a baghouse dust collector for waste liquid incineration includes a dust inlet pipe 1, which is connected and fixed to the left side of the outer wall of the baghouse dust collector body 2. A dust outlet funnel 3 is fixed to the bottom surface of the baghouse dust collector body 2. A top cover 4 is bolted to the top surface of the baghouse dust collector body 2. A fan 5 is provided on the right side of the outer wall of the baghouse dust collector body 2. An air guide pipe 6 is connected and fixed between the fan 5 and the baghouse dust collector body 2. A drive motor 7 is fixed to the inner top surface of the top cover 4. A rotating shaft 8 is fixed to the output shaft of the drive motor 7. The left side of the rotating shaft 8... Connecting rods 9 are fixed on the sides and right sides respectively. The connecting rods 9 are hollow structures. Connecting posts 10 are slidably inserted into the interior of the two connecting rods 9 respectively. Cleaning brushes 11 are fixed to the outer ends of the two connecting posts 10 respectively. Several first threaded grooves 12 are opened on the top surface of the two connecting posts 10 respectively. First threaded holes 13 are opened on the top surface of the two connecting rods 9 respectively. First bolt bodies 14 are threadedly connected to the two first threaded holes 13 respectively. The threaded end of the first bolt body 14 is threadedly connected to the interior of the first threaded groove 12.

[0023] During use, the operator first slides the connecting column 10 into the inside of the connecting rod 9, then adjusts the distance between the two cleaning brushes 11 to ensure that the two cleaning brushes 11 can contact the inner wall of the bag filter body 2, and then fixes it with the first bolt body 14. Next, the top cover 4 is installed on the top surface of the bag filter body 2 with bolts to complete the installation. Then, the fan 5 is started. After the fan 5 is turned on, it drives the airflow, causing the gas containing dust from the waste liquid incineration to enter the bag filter body 2 from inside the dust inlet pipe 1. After the gas enters the bag filter body 2, large particles of impurities in the gas are... The dust falls from the inside of the dust outlet funnel 3 to the outside of the bag filter body 2 due to its own gravity. The small gas particles float upwards and are adsorbed by the device inside the bag filter body 2. The adsorbed gas enters the inside of the air guide duct 6 and is then blown from the inside of the fan 5 to the outside of the bag filter body 2. Then, the drive motor 7 is started, which makes the rotating shaft 8 rotate, thereby driving the two cleaning brushes 11 to rotate, which can clean the inner wall of the bag filter body 2, achieving the effect of mechanical cleaning. Finally, the dust adhering to the inner wall of the bag filter body 2 falls out from the inside of the dust outlet funnel 3.

[0024] The drive motor 7, rotating shaft 8, and cleaning brush 9 facilitate the cleaning of the inner wall of the bag filter body 2. At the same time, the distance between the two cleaning brushes 9 can be adjusted by the connecting rod 9, connecting column 10, and first bolt body 14. This allows for corresponding adjustments based on the internal dimensions of the bag filter body 2 of different sizes, thereby improving the flexibility and practicality of the device.

[0025] like Figure 1 , Figure 2 and Figure 4 As shown, the bag filter body 2 has two venturi tubes 15 fixedly connected inside. An air tank 16 is fixed on the left side of the outer wall of the bag filter body 2. Pulse valves 17 are respectively provided between the air tank 16 and the two venturi tubes 15. Several nozzles are provided on the bottom surface of the two venturi tubes 15. Two support columns 18 are fixed on the inner wall of the bag filter body 2. Several frames 19 are fixed on the bottom surface of the two support columns 18. Dust collection bags 20 are provided on each of the several frames 19.

[0026] During use, when the fan 5 is turned on, the gas containing dust enters the body 2 of the bag filter. Large particles of impurities in the gas fall off under the action of gravity, while small particles of gas are adsorbed by the dust collection bags 20. In order to maintain the cleanliness and dust removal efficiency of the dust collection bags 20, the pulse valve 17 needs to be opened periodically. After the pulse valve 17 is opened, the gas inside the air tank 16 is blown towards the dust collection bags 20 through the venturi tube 15 and the nozzle. This pulse jet method causes the dust adsorbed on the outer wall of the dust collection bags 20 to fall off from the dust outlet funnel 3 under the action of wind, thereby maintaining the cleanliness and dust removal efficiency of the dust collection bags 20.

[0027] like Figure 1 , Figure 2 and Figure 4 As shown, the top surface of the air duct 6 has an installation hole 21, and a filter screen 22 is detachably installed inside the installation hole 21. A fixing plate 23 is fixed to the top surface of the filter screen 22. The top surface of the air duct 6 has two second threaded grooves 24, and the top surface of the fixing plate 23 has two second threaded holes 25. The two second threaded holes 25 are respectively threaded with second bolt bodies 26, and the threaded ends of the two second bolt bodies 26 are respectively threaded with the inside of the two second threaded grooves 24.

[0028] During use, an installation hole 21 is provided on the top surface of the air duct 6, and a filter screen 22 is detachably installed therein. When the purified gas is discharged through the air duct 6, the filter screen 22 can further filter out the tiny impurities in the gas, preventing them from entering the fan 5 and causing damage. The filter screen 22 is connected to the air duct 6 through the fixing plate 23 and the second bolt body 26. The operator can easily remove the filter screen 22 from the air duct 6 for cleaning or replacement simply by loosening the second bolt body 26.

[0029] like Figure 1 , Figure 2 and Figure 4 As shown, a sealing ring 27 is fixed to the bottom surface of the fixing plate 23, and a collection box 28 is provided at the bottom end of the dust outlet funnel 3.

[0030] During use, a sealing ring 27 is fixed to the bottom surface of the fixing plate 23. When the filter screen 22 is installed on the air guide duct 6, the sealing ring 27 can tightly fit the top surface of the air guide duct 6 to prevent gas leakage from the mounting hole 21. A collection box 28 is provided at the bottom of the dust discharge funnel 3. When large particles of impurities fall from the dust discharge funnel 3, they will be collected in the collection box 28. The staff can clean the impurities in the collection box 28 regularly to ensure the normal operation of the bag filter dust collector.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
