Description

Technical Field

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

[0002] Dry dust collector is a common industrial dust removal equipment, which is used to remove dust and particulate matter from the air during the production process. It separates the dust by its own gravity or inertia, thereby achieving the dust removal effect. This dust collector is suitable for many industries, such as mining, building materials, metallurgy, etc., and plays an important role in environmental protection and safe production.

[0003] In existing dry dust collectors, after multiple filtrations, dust particles will be attached to the filter chamber inside the filter, which will clog the filter channel and affect the filtering and dust removal effect.

When part of the inlet pipe 14 is not in use, the sealing cover 15 can be tightened and fastened to the outer side of the inlet pipe 14 to achieve the sealing at the inlet pipe 14. The upper end of the dust removal box 1 is fixedly installed with an upper cover 2, and the upper end of the upper cover 2 and one side of the secondary filter bin 121 are penetrated and connected with an outlet pipe 22, and the primary filter bin 121 is provided with a sealing cover 15. The upper ends of the bins 111 and the secondary filtering bins 121 are welded with support frames 3, and slide seats 31 are welded on both sides of the upper ends of the support frames 3. A connecting plate 32 is welded on the upper ends of the slide seats 31, and a hydraulic rod 4 is fixedly installed on the upper ends of the connecting plates 32. A filtering bin 5 is movably installed on the lower ends of the support frames 3, and an upper frame 51 is welded on the upper ends of the filtering bins 5, and the telescopic ends of the hydraulic rods 4 abut against the upper ends of the upper frames 51. An upper filter screen 56 is fixedly installed on the upper ends of the filtering bins 5, and the middle position of the inner part of the filtering bins 5 A lower filter screen 57 is fixedly installed, a fixed frame 58 is welded to the outer side of the filter bin 5, and a spring 6 is welded to the lower end of the fixed frame 58. When the funnel 7 is fixed to the lower end of the dust removal box 1, the filter bin 5 will be squeezed to the upper end of the inner part of the dust removal box 1 through the elastic squeezing force of the spring 6, so as to prepare for the subsequent hydraulic rod 4 to apply a pushing force to complete the dust shaking operation. The lower end of the dust removal box 1 is bolted with a funnel 7, and the upper end of the funnel 7 abuts against the lower end of the spring 6, and the lower end of the funnel 7 is bolted with a dust collecting box 8.

[0026] Furthermore, a through groove 112 is formed through the upper end of the side surface of the partition 11 close to the filter bin 5, and the through groove 112 connects the primary filter bin 111 and the filter bin 5. A through groove 122 is formed through the lower end of the side surface of the partition 2 close to the filter bin 5, and the through groove 122 connects the secondary filter bin 121 and the filter bin 5, thereby dividing the dust removal box 1 into two dust removal spaces, the primary filter bin 111 and the secondary filter bin 121, so as to achieve a better dust removal effect.

[0027] Furthermore, a sealing plate 21 is welded to the lower end of the upper cover 2, and the sealing plate 21 abuts against the upper end of the dust removal box 1. The sealing plate 21 seals the upper cover 2 and the dust removal box 1. When the filter bin 5 needs to be disassembled for maintenance, the upper cover 2 can be removed.

[0028] Furthermore, the interior of the slide 31 is a hollow structure, and sliders 52 are welded on both sides of the upper end of the upper frame 51, and the sliders 52 are slidably installed inside the slide 31. When the filter bin 5 shakes off the dust, the slider 52 at the upper end of the filter bin 5 slides inside the slide 31, so that the filter bin 5 can slide along the preset path inside the slide 31, avoiding the phenomenon of deviation.

[0029] Furthermore, a connecting hole 33 is provided on the upper surface of the support frame 3 and on the inner side of the two sets of slide seats 31, and the hydraulic rod 4 is fixedly installed inside the connecting hole 33. A push block 41 is fixedly installed on the telescopic end of the hydraulic rod 4. A groove 53 is provided on the upper end of the upper frame 51 and on the inner side of the slide block 52, and the groove 53 abuts against the lower surface of the push block 41. When it is necessary to shake the dust from the filter bin 5, the hydraulic rod 4 can be controlled to perform a telescopic operation. At this time, the push block 41 pushes the filter bin 5 to move downward. After being pushed into position, the hydraulic rod 4 is quickly retracted. At this time, the filter bin 5 is elastically deformed by the spring 6, which will quickly push the filter bin 5 upward and reset it. During the resetting process, the spring 6 will gradually recover from the elastic deformation to the static state. During this process, shaking will occur for a certain period of time, thereby shaking off the dust attached to the inside of the filter bin 5, thereby completing the self-cleaning of the filter bin 5.

[0030] Furthermore, movable holes 34 are formed on both sides of the left and right sides of the support frame 3, a threaded rod 54 is welded on the upper end of the upper frame 51, and the threaded rod 54 is movably installed inside the movable hole 34, and a nut 55 is threadedly sleeved on the outer side of the threaded rod 54 and located above the upper frame 51. By adjusting the position of the nut 55 sleeved on the outer side of the threaded rod 54, the shaking amplitude of the filter bin 5 can be changed, and the sliding distance of the filter bin 5 can be indirectly adjusted and fixed. At the same time, when the funnel 7 is removed, the lower end of the filter bin 5 loses its abutment and will fall downward with the funnel 7 until the lower surface of the nut 55 fits with the upper surface of the support frame 3. At this time, the filter bin 5 will not be able to continue to fall, and when the funnel 7 is disassembled, the nut 55 is unscrewed to remove the filter bin 5.

[0031] Furthermore, a connecting seat 71 is welded to the upper end of the funnel 7, and the connecting seat 71 is inserted into the lower end of the dust removal box 1. The upper surface of the connecting seat 71 abuts against the spring 6. A mounting plate 72 is welded to the outer side of the connecting seat 71, and the mounting plate 72 is bolted to the outer side of the lower end of the dust removal box 1. When the funnel 7 is installed in place, its connecting seat 71 will abut against the spring 6, thereby squeezing the filter bin 5 upward, preparing for subsequent elastic dust shaking.

[0032] Working principle: First, a dry dust collector is moved to the working position. In the first step, the airflow with dust enters from the inlet pipe 14 and flows into the preliminary filter bin 111. After being filtered by the lower filter screen 57 and the upper filter screen 56 in the filter bin 5, it flows into the transition bin 13 through the through groove 112, and then flows into the secondary filter bin 121 through the through groove 2 122. After being filtered by the filter bin 5, it flows out from the outlet pipe 22. In the second step, the lower filter screen 57 and the upper filter screen 56 block the dust. The blocked dust particles fall into the dust box 8 through the funnel 7. In the third step, the filter bin 5 is mechanically cleaned regularly, and the hydraulic rod 4 is controlled to operate. The hydraulic rod 4 pushes the push block 41 toward the lower end through the telescopic end, thereby applying a downward squeezing force to the filter bin 5. In the fourth step, after the hydraulic rod 4 is extended into place, it is quickly retracted. At this time, the spring 6 recovers its deformation and pushes the filter bin 5 upward. At the same time, the spring 6 exerts its elastic properties to drive the filter bin 5 to shake at different frequencies until it is reset, thereby shaking off the dust attached to the inner wall of the filter bin 5, thus achieving preliminary cleaning of the filter bin 5. In the fifth step, the filter bin 5 is regularly disassembled and cleaned. First, the funnel 7 and the upper cover 2 are removed, and then the nut 55 is unscrewed. At this time, the filter bin 5 and the dust removal box 1 are in an active and detachable state, thus completing the use process of a dry dust collector.

[0033] It should be noted that the electrical components appearing in this article are all connected to an external main controller and 220V AC power, and the main controller can be a conventional known device for control such as a computer.
