Description

Technical Field

[0001] The utility model relates to the technical field of sludge drying pre-dust removal, in particular to a pre-dust removal mechanism of a sludge drying device. Background Technique

[0002] Sludge drying, also known as sludge dewatering, refers to the process of removing most of the water content from sludge through percolation or evaporation. For the method of drying sludge by heating and evaporation, dust will be generated during the drying process. In order to prevent the tail gas generated during the heating and evaporation of sludge drying from condensing and mixing with dust to form sludge, it is necessary to pre-dust the tail gas generated during the heating and evaporation of sludge drying.

[0003] Most of the pre-dust removal mechanisms of sludge drying devices use bag dust removal filters. Since a large amount of dust is generated during the sludge drying process, the replacement frequency of the filter bags in the bag dust removal filter is relatively high, which brings certain inconvenience to users. In order to avoid frequent replacement of filter bags, some pre-dust removal mechanisms use dust removal filter meshes for filtering and dust removal. However, the dust removal filter meshes are easily blocked, and the filtered dust is not easy to clean. During the process of cleaning the dust, when the dust enters the inside of the collection box and the collection box is pulled out, the dust inside the collection box is easily mixed into the equipment working environment, which will cause certain harm to the respiratory system of the staff and seriously affect the environment of the equipment working area. Therefore, it is necessary to improve a pre-dust removal mechanism of a sludge drying device to solve the above problems. Content of the Utility Model

[0028] Further, two sets of cams 212 are provided and symmetrically distributed about the center line of the front surface of the dust removal box body 1. Another cam 212 is fixedly installed on the front surface of the second synchronous pulley 215. The mounting frame 217 is slidably installed inside the dust removal box body 1. The mounting frame 217 is arranged at the bottom of the air outlet pipe 5, facilitating the knocking of the filter net 218.

[0029] Further, the dust reduction assembly 22 includes a water storage tank 221. The water storage tank 221 is fixedly installed on the right side of the dust removal box body 1. A water inlet pipe 222 is fixedly installed on the front surface of the water storage tank 221. A lifting plate 223 is slidably installed inside the water storage tank 221. An elastic insertion block 224 is fixedly installed at the bottom of the lifting plate 223. A second spring 225 is fixedly installed at the bottom of the lifting plate 223.

A through hole is formed at the corresponding position of the water storage tank 221 and the push rod 226, and the push rod 226 passes through the through hole and is arranged at the bottom of the water storage tank 221, controlling the amount of dripping water to prevent too much water from dripping into the collection box 227 and generating silt.

[0031] Embodiment 2:

[0032] Please refer to Figure 4 , and in combination with Embodiment 1, it is further obtained that the disassembly mechanism 3 includes a third spring 31. The third spring 31 is fixedly installed inside the mounting frame 217. One end of the third spring 31 away from the mounting frame 217 is fixedly installed with a sliding block 32. One end of the sliding block 32 away from the third spring 31 is fixedly installed with an arc-shaped insertion block 33. A dial block 34 is fixedly installed at the top of the sliding block 32, for replacing or further cleaning the filter net 218, facilitating the effective progress of subsequent filtering operations.

[0033] Further, the sliding block 32 is slidably installed inside the mounting frame 217. A slot is formed at the corresponding position of the filter net 218 and the arc-shaped insertion block 33, and the arc-shaped insertion block 33 is inserted into the slot, facilitating the removal of the filter net 218.

[0034] In actual operation, when this device is used, the tail gas mixed with dust generated by heating and evaporation in the sludge drying equipment is passed into the dust removal box body 1, and then filtered through the filter 218. The motor 211 is started, and the output end of the motor 211 drives the cam 212 to rotate. The rotation of the cam 212 drives another cam 212 to rotate through the synchronous wheel 1 213, the synchronous belt 214 and the synchronous wheel 215, and then the mounting frame 217 is knocked. Because the filter 218 and the mounting frame 217 are plug-in installed, the dust at the bottom of the filter 218 will also be knocked off during the knocking of the mounting frame 217, and the dust falls into the collection box 227. After the dust removal operation is completed, the collection box 227 is pulled out, and the collection box 227 is easy to be pulled out under the action of the support roller 7. During the pulling-out process, after the fixed rod 228 touches the top rod 226, the top rod 226 is lifted upward, and the top rod 226 lifts the lifting plate 223, thereby causing the elastic plug block 224 to detach from the drip hole, so that the water inside the water storage tank 221 drips into the collection box 227, and the dust inside the collection box 227 is reduced. After the top rod 226 moves to the area without the fixed rod 228, the lifting plate 223 moves downward under the action of the spring 225, thereby causing the elastic plug block 224 to be inserted into the drip hole, thereby controlling the amount of dripping water, preventing too much water from dripping into the collection box 227 and generating sludge. The box door 6 is opened, and the block 34 is pushed outward to cause the arc-shaped block 33 to detach from the plug-in position of the slot of the filter screen 218, and then the filter screen 218 is taken out and replaced or further cleaned.
