Description

Technical Field

[0001] The utility model relates to the technical field of dust blowers, in particular to a dust collector blowing structure. Background Art

[0002] The bag filter is composed of three parts: the filter body, the pulse jet cleaning system and the dust conveying system. The dust-laden gas enters from the lower part of the middle box, passes through the buffer zone first, and then passes through the filter bag from the outside to the inside. The dust is retained on the outside of the filter bag, and the clean gas is discharged from the bag mouth to the upper box in the filter bag.

[0003] After a long period of use, the filter bag will cause a lot of dust to adhere to the surface of the filter bag, affecting the air permeability of the filter bag. Therefore, it is necessary to use compressed air to blow and clean the filter bag. However, the nozzle of the existing purge pipe is generally set at the bag mouth of the filter bag, resulting in low cleaning efficiency of the filter bag. In addition, the multiple filter bags of some existing dust collectors are mostly distributed in an array on a rectangular frame. Since the nozzle of the purge pipe is mostly fixed, the airflow can only purge the fixed position of the filter bag, affecting the cleaning efficiency of the filter bag. Therefore, it is necessary to design a dust collector purge structure to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art and to propose a dust collector purge structure. The purge structure places a bent pipe into a filter bag, and utilizes the operation of a driving motor to drive multiple bent pipes to move left and right, so that the bent pipe can purge various positions on the bottom of the filter bag, thereby improving the purge effect on the filter bag. By alternately conducting the two branch pipes, multiple filter bags are allowed to swing, thereby shaking off the dust adhered to the filter bags.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 5 A dust collector purge structure comprises an installation box 1, the lower end of the installation box 1 is provided with an opening, and a sealing door is provided in the opening for convenience of subsequent cleaning. The upper end of the installation box 1 is fixedly connected with a top cover 2, and a mounting frame 15 is fixedly connected in the installation box 1. A plurality of filter bags 16 are installed on the mounting frame 15, and a rectangular groove is provided at the lower end of the top cover 2. A driving motor 7 is installed on the right side of the top cover 2. A reciprocating screw rod 11 is fixedly connected to the end of the output shaft of the driving motor 7, and the reciprocating screw rod 11 passes through the rectangular groove. A moving block 12 is threadedly connected to the reciprocating screw rod 11, and the moving block 12 is slidably connected to the inner walls of the front and rear sides of the rectangular groove. A plurality of fixed blocks are fixedly connected to the lower end of the moving block 12, and a plurality of fixed blocks are fixedly connected to each other with a bent pipe 14, and a fan 3 is installed on the upper end of the top cover 2. The air outlet end of the fan 3 is connected with a main pipe 4, and the main pipe 4 is connected with a plurality of bent pipes 14 through a hose 13, and the lower ends of the plurality of bent pipes 14 extend into the corresponding filter bags 16.

[0023] The bottom space of the installation box 1 is connected to an air inlet pipe 6 , and the top space of the installation box 1 is connected to an air outlet pipe 8 .

[0024] Among them, the front and rear sides of the curved pipe 14 are connected with branch pipes 17, and the two branch pipes 17 are provided with solenoid valves, which are normally closed solenoid valves. A touch rod 10 is fixedly connected to the reciprocating screw 11, and a plurality of conductive blocks 9 are fixedly connected to the left side of the top cover 2, two of which are located above the reciprocating screw 11, and the other two conductive blocks 9 are located on the rear side of the reciprocating screw 11. A power supply is provided on the mounting box 1, and the power supply, the two conductive blocks 9 located at the top, the touch rod 10 and the solenoid valve on the branch pipe 17 on the rear side of each curved pipe 14 form a loop through wires, and the power supply, the two conductive blocks 9 located at the rear side, the touch rod 10 and the solenoid valve on the branch pipe 17 on the front side of each curved pipe 14 form a loop through wires, and the left side of the top cover 2 is fixedly connected to the protective box 5, and a plurality of conductive blocks 9 and the touch rod 10 are all located in the protective box 5.

[0025] The functional principle of the utility model can be explained by the following operation mode: when the dust collector is in operation, dust will enter the installation box 1 through the air inlet pipe 6 along with the air flow, and then be discharged through the air outlet pipe 8, so that the dust adheres to the outer sides of the plurality of filter bags 16;

[0026] When the filter bag 16 needs to be purged, the drive motor 7 and the fan 3 are started. The operation of the fan 3 is injected into the multiple curved pipes 14 through the main pipe 4, so as to purge the area below the filter bag 16. The operation of the drive motor 7 causes the moving block 12 to move left and right, thereby causing the multiple curved pipes 14 to move left and right, thereby cleaning the multiple filter bags 16.

[0027] During the rotation of the reciprocating screw rod 11, the touch rod 10 will alternately contact multiple conductive blocks 9. When the touch rod 10 contacts the two conductive blocks 9 located above, the solenoid valve on the branch pipe 17 on the rear side of each curved pipe 14 will be energized and turned on, so that the multiple branch pipes 17 will spray airflow to the rear side, causing the filter bag 16 to blow to the rear side. When the touch rod 10 contacts the two conductive blocks 9 located on the rear side, the solenoid valve on the branch pipe 17 on the front side of each curved pipe 14 will be energized and turned on, so that the multiple branch pipes 17 will spray airflow to the front side, causing the filter bag 16 to blow to the front side. The branch pipes 17 on the front and rear sides of each curved pipe 14 are alternately turned on, so that the filter bag 16 can swing, and the dust on the filter bag 16 can be shaken off.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
