Abstract

This utility model provides a high negative pressure multi-point induced draft dust removal and ash extraction device, belonging to the technical field of extraction devices. It includes a silo pump and a filter chamber mounted on the pump. The pump has a feed inlet at its upper end and a discharge inlet at its lower end. A butterfly valve is installed on one side of the feed inlet, and a discharge device is installed at the lower end of the discharge inlet. A conveying pipe is installed at the lower end of the discharge device. This utility model utilizes an inclined block and a squeezing rod to achieve up-and-down vibration of the elastic cloth, causing dust adhering to the material particles to detach.

[0026] Example, refer to Figures 1-6 A high negative pressure multi-point induced draft dust removal and ash suction device includes a silo pump 1 and a filter silo 5 installed on the silo pump 1. The upper end of the silo pump 1 is provided with a feed port 11 and the lower end of the silo pump 1 is provided with a discharge port 12. A butterfly valve 2 is installed on one side of the feed port 11 and a discharge device 3 is installed at the lower end of the discharge port 12. A conveying pipe 4 is installed at the lower end of the discharge device 3. An air supply damper 41 is installed at one end of the conveying pipe 4. A slide valve 42 is installed on one side of the conveying pipe 4 and a high pressure conveying pump 43 is installed at one end of the conveying pipe 4.

[0027] The lower end of the filter chamber 5 is fixedly connected to one end of the feed port 11. A dust suction pipe 51 is installed on the upper inner wall of the filter chamber 5. Symmetrical feed pipes 52 are installed on the inner walls of the filter chamber 5 near the dust suction pipe 51. Symmetrical fixing plates 53 are installed on the inner walls of both sides of the filter chamber 5. A fixing frame 54 is installed on the inner wall of the filter chamber 5 near the two fixing plates 53. An elastic cloth 55 is installed between the fixing plate 53 and the fixing frame 54. An installation plate 551 is installed at the lower end of the elastic cloth 55. An inclined block 56 is installed at the lower end of the installation plate 551. Symmetrical rotating shafts 8 are installed on the inner wall of the filter chamber 5. A collar 81 is installed on the outer wall of the rotating shaft 8. Multiple extrusion rods 82 are installed on the outer wall of the collar 81. A baffle 10 is installed below the fixing frame 54.

[0028] Furthermore, the two ends of the unloader 3 are connected and fixed to the silo pump 1 and the conveying pipe 4 respectively through flange rings and bolts. The output pipe of the high-pressure conveying pump 43 is connected to the material collection assembly. The dust suction pipe 51 is connected to the external dust suction assembly. The feeding pipe 52 is connected to the dust removal silo. The fixing plate 53 and the fixing frame 54 are both fixed to the inner wall of the filter chamber 5. The two ends of the elastic cloth 55 are fixedly connected to the side walls of the fixing plate 53 and the fixing frame 54 respectively. The two sides of the mounting plate 551 are fixedly connected to the outer walls of the elastic cloth 55 and the inclined block 56 respectively. One end of the rotating shaft 8 is connected to the first electric... The output end of the machine 6 is fixedly connected, and one end of the rotating shaft 8 is fixedly connected to the first transmission wheel 83. The two first transmission wheels 83 are connected by a first transmission belt 84. The outer wall of the rotating shaft 8 is fixedly connected to the inner wall of the collar 81. The outer wall of the collar 81 is fixedly connected to one end of the extrusion rod 82. One end of the extrusion rod 82 slides against the inclined surface of the inclined block 56. The two ends of the baffle 10 are fixedly connected to the fixed shaft 101. The outer wall of the fixed shaft 101 is rotatably connected to the inner wall of the filter chamber 5. One of the fixed shafts 101 is fixedly connected to the output end of the second motor 7.

[0029] It should be noted that: the material is conveyed to the silo pump 1 through the feeding pipe 52 connected to the dust collection silo, and the suction pipe 51 is connected to the external dust collection component. During operation, the first motor 6 is started to drive the rotating shaft 8 to rotate the outer collar 81. During the rotation of the collar 81, one end of the outer pressing rod 82 slides against the inclined surface of the inclined block 56. From the moment the pressing rod 82 contacts the inclined block 56 until it disengages, the pressing rod 82 is pushed and pushes a local area of ​​the upper elastic cloth 55 to deform upwards. At the moment the pressing rod 82 disengages, it rebounds, thereby realizing the up-and-down vibration of the elastic cloth 55. During this vibration, the material on the elastic cloth 55 will vibrate and bounce up. The dust adhering to the material particles is removed, and then the dust in the material is cleaned by the suction pipe 51. After the dust in the material is cleaned, the second motor 7 is started to open the baffle 10 and the butterfly valve 2 is started to allow the material to enter the silo pump 1. Then the unloader 3 is started to allow the material particles in the silo pump 1 to fall into the conveying pipe 4 by gravity. Then the slide valve 42 and the high-pressure conveying pump 43 are started to transport the granular material through the conveying pipe 4 to the material collection assembly. When there is insufficient air in the conveying pipe 4, the air intake flow can be changed by the air supply damper 41 to ensure efficient material conveying. The filter assembly can effectively clean the dust in the material and improve the quality of the subsequent granular material.

[0030] Furthermore, a stirring shaft 9 is rotatably connected to the inner wall of the filter chamber 5 near the fixed frame 54, and multiple stirring blades 91 are fixedly connected to the outer wall of the stirring shaft 9. A second transmission wheel 92 is fixedly connected to one end of the stirring shaft 9, and a first transmission wheel 83 is fixedly connected to one end of one of the rotating shafts 8 near the second transmission wheel 92. A second transmission belt 93 is drivingly connected between the first transmission wheel 83 and the second transmission wheel 92.

[0031] It should be noted that while the rotating shaft 8 is rotating, the stirring shaft 9 is driven to rotate simultaneously by two transmission wheels and the second transmission belt 93. During the rotation, the multiple stirring blades 91 on the outside of the stirring shaft 9 continuously stir the material between the baffle 10 and the fixed frame 54. During the stirring process, the material particles are constantly being turned up and falling. In the process of turning up and falling, the dust mixed between the material particles is scattered into the space inside the filter chamber 5. Then, the dust is absorbed and cleaned by the suction pipe 51, which improves the dust cleaning effect and further improves the quality of the subsequent material particles.

[0032] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
