Description

Technical Field

[0001] The utility model relates to the technical field of drying machines, in particular to a high-efficiency dust removal mechanism for a drum type drying machine. Background Art

[0002] The drum dryer is one of the traditional drying equipment. It is reliable, flexible, adaptable and has large processing capacity. It is widely used in metallurgy, building materials, chemical industry, coal washing, fertilizer, ore, sand, clay, kaolin, sugar and other fields. The length is determined according to the drying requirements. The wet material entering the drying cylinder is repeatedly picked up and thrown down by the lifting plate on the wall of the rotating cylinder. In the process of falling, it is broken into fine particles by the scattering device, and the specific area is greatly increased. It is fully in contact with and dried by the hot air, which accelerates the drying heat and mass transfer.

[0003] The dryer puts the material to be dried into it for drying, but the material may contain light impurities such as dust, and a large amount of dust may be generated during the drying process. These will remain in the oven, causing subsequent materials to be contaminated with the dust accumulated in the oven during the drying process, affecting the drying quality and effect. Therefore, dust removal is required. Some existing dryers do not have dust removal function and cannot remove dust during the drying process, which is inconvenient for later material processing and brings considerable trouble to later processing. At the same time, the materials that need to be dried are of different materials. When drying materials of some materials, the materials may produce irritating gases due to high temperature, and some existing dryers cannot purify the irritating gases. During the drying process, the exhaust gas generated will affect the air quality of the working environment. Working in this environment for a long time will seriously affect the physical and mental health of the staff. Utility Model Content

The air outlet of the suction pipe 3 is connected with the fan 5, and the fan 5 is located on one side of the dryer body 1. The fan 5 is used in conjunction with the suction pipe 3 to transmit the dust collected by the dust suction mechanism 4. The air outlet of the fan 5 is connected with a dust collecting shell 6, which is located on one side of the fan 5. The bottom of the dust collecting shell 6 is provided with a water collecting tank. The dust collecting shell 6 is used to collect dust and perform dust reduction treatment to avoid dust floating in the air when the staff is cleaning the dust, polluting the working environment or the health of some staff. Positioning grooves 7 are provided on both sides of the lower inner wall of the dust collecting shell 6, and the inner wall of the positioning groove 7 is slidably connected with a positioning block 8 The positioning groove 7 cooperates with the positioning block 8 to position the parts on one side, and can guide the parts on one side at the same time, so that the staff can extract the parts. A collecting shell 9 is fixedly connected to one side of the positioning block 8. The collecting shell 9 is located below the air inlet of the dust collecting shell 6. The collecting shell 9 is slidably connected to the inner wall of the dust collecting shell 6. A filter plate is installed at the bottom of the collecting shell 9. The collecting shell 9 is used to collect dust wetted by water and filter excess water through the filter plate at the bottom thereof, which is convenient for recycling water resources and reducing water resource waste. A dust reduction mechanism 10 is provided on the top of the dust collecting shell 6. The dust reduction mechanism 10 is used to spray water when the fan 5 transfers dust to the inside of the dust collecting shell 6, so that the dust after being wetted by water falls into the inside of the collecting shell 9, thereby avoiding dust from floating and improving the dust removal effect. A guide plate 11 is fixedly connected to the top of the inner wall of the dust collecting shell 6, and the guide plate 11 is located above the collecting shell 9.

The purification mechanism 13 is used to filter the exhaust gas generated during drying, so as to prevent the exhaust gas generated when drying individual materials from reducing the quality of the working environment air and improve the use effect of the device.

[0024] The dust suction mechanism 4 includes a dust suction pipe 41 connected to the surface of the suction pipe 3. The number of the dust suction pipes 41 is several, and the dust suction pipes 41 are symmetrical and staggered in pairs. Ventilation holes 42 are opened on both sides of the surface of the dust suction pipe 41. The number of the ventilation holes 42 is several and evenly distributed on both sides of the surface of the ventilation holes 42. The interior of the ventilation holes 42 is fixedly connected with a filter 43. Under the action of the fan 5, dust is sucked through the suction pipe 3 and the dust suction pipe 41. When dust enters the interior of the dust suction pipe 41 through the ventilation holes 42, the filter 43 blocks the particulate material to prevent the material from being sucked into the interior of the suction pipe 3 to cause blockage and affect the dust suction effect. At the same time, the suction pipe 3 and the dust suction pipe 41 are driven to rotate by the rotating component of the dryer body 1, so that the material can be turned and dried more evenly, effectively improving the drying effect.

[0025] The dust suppression mechanism 10 includes a circulating water pump 101 connected to the lower side of the dust collecting shell 6. The water outlet of the circulating water pump 101 is connected to a water distribution tank 102. The water distribution tank 102 is located at the top of the dust collecting shell 6.

The bottom of the water distribution tank 102 is connected to a nozzle 103. The number of nozzles 103 is several and evenly distributed at the bottom of the water distribution tank 102. The nozzle 103 is located above the guide plate 11. When the fan 5 blows the dust in the dryer body 1 When the dust is transferred to the inside of the dust collecting shell 6, water is sprayed through the nozzle 103, so that the dust adheres to the water and falls into the inside of the collecting shell 9 with the gravity of the water, and the dust is reduced to prevent the dust from floating in the air. The excess water is filtered by the filter plate at the bottom of the collecting shell 9 into the collecting cavity at the bottom of the inner wall of the dust collecting shell 6, which is convenient for collecting the dust. The filtered water is then pumped to the inside of the water distribution tank 102 for recycling through the circulating water pump 101, thereby reducing the waste of water resources and effectively improving the dust removal effect.

The activated carbon plate 133 is slidably connected to the inner wall of the ventilation shell 131. When the dust is sucked into the dust collecting shell 6, the extracted exhaust gas enters the interior of the ventilation shell 131 through the dustproof net 12, and is purified and filtered by the activated carbon plate 133. The air conveying effect is improved by the setting of the fan blade 132. When the purification effect of the activated carbon plate 133 is reduced after long-term use, the activated carbon plate 133 can be pulled out for replacement. The operation is simple and the activated carbon plate 133 is convenient to replace.

[0027] It is worth noting that the dryer body 1 proposed in this technical solution is a prior art, and its working principle and beneficial effects when used are not described in detail here.

At the same time, the dust in the material is sucked into the interior of the suction pipe 3 through the ventilation hole 42, and the material is blocked by the filter screen 43. Then the dust is transmitted to the interior of the dust collecting shell 6 through the fan 5, and water is sprayed through the nozzle 103, so that the dust adheres to the water and falls into the interior of the collecting shell 9 with the gravity of the water, so as to facilitate the unified cleaning of the dust, and the excess water is filtered to the bottom of the dust collecting shell 6 through the filter plate at the bottom of the collecting shell 9, and then pumped to the interior of the water distribution tank 102 through the circulating water pump 101 for recycling. Then the extracted gas enters the interior of the ventilation shell 131 through the dustproof net 12, and the exhaust gas is purified by the activated carbon plate 133 to avoid the irritating odor caused by drying affecting the air quality. The activated carbon plate 133 can be replaced according to its usage. After the drying is completed, the collecting shell 9 is pulled out to clean the dust.
