Description

Technical Field

[0001] The utility model belongs to the technical field of lime dust removal, and in particular relates to a lime silo dust removal device. Background Art

[0002] Lime silo is a facility for storing lime, usually in cylindrical form, which is easy to load, unload and store. This structure helps to maintain the dryness and stability of the lime, ensuring its quality is not affected. Lime silo is widely used in industry and construction. During the use of lime silo, dust removal device is required to remove dust from the inside of the lime silo.

[0003] In phosphorus chemical wastewater treatment, lime is the main treatment agent with a large demand, and is usually stored in silos. Most of the original lime silos are equipped with bag dust collectors on the top and are equipped with fans. The dust collectors need to be cleaned regularly during the use of the device. However, due to the high height of the lime silo, the dust collector is difficult to repair. At the same time, dust will escape when the dust removal device is working, and the escape is not conducive to recovery, causing dust pollution to the environment. Utility Model Content

[0025] A lime silo dust removal device comprises a silo body 1, a water seal tank 4 and a lime preparation tank 12; an ash discharge pipe 3 is fixedly connected and interspersed between the silo body 1 and the water seal tank 4, and a lime truck ash unloading pipe 2 is fixedly connected to one side of the outer surface of the silo body 1, so that the lime dust generated by the silo body 1 when unloading ash will enter the water seal tank 4 through the ash discharge pipe 3.

[0026] A fixed pipe 5 is fixedly connected to the top of the water seal groove 4, and a first flange 7 is fixedly connected to the top of the fixed pipe 5. A mounting pipe 14 is installed on the fixed pipe 5 through the first flange 7. A dust removal component is arranged in the mounting pipe 14, which can change the state of the dusty lime and send it into the water seal groove 4.

[0027] An overflow pipe 9 and a drain pipe 10 are fixedly connected and inserted on one side of the water seal tank 4. The drain pipe 10 is located below the overflow pipe 9. A valve 11 is installed on the outer surface of one side of the drain pipe 10. The ends of the overflow pipe 9 and the drain pipe 10 away from the water seal tank 4 are movably connected and inserted in the lime preparation tank 12. The drain pipe 10 can timely guide the lime slag in the water seal tank 4 into the lime preparation tank 12 to prevent blockage caused by excessive slag accumulation, thereby ensuring the continuous operation of the water seal tank 4. The overflow pipe 9 can collect dust escaping from the water seal tank 4 into the water of the lime preparation tank 12.

[0028] The dust removal assembly may include an inlet pipe 16, the bottom end of the inlet pipe 16 is fixedly connected to a standpipe 19, four distribution pipes 17 are fixedly connected and interlaced at equal distances on the upper outer surface and the lower outer surface of the standpipe 19, and two nozzles 18 are fixedly connected to the outer surface of the bottom end of the distribution pipe 17. One end of the inlet pipe 16 is connected to a water distribution pipe 8. When in use, the water distribution pipe 8 will introduce water into the inlet pipe 16, and then introduce it into the distribution pipe 17 fixedly connected thereto through the inlet pipe 16, and then spray it through the nozzle 18 to cool and remove the lime dust.

[0029] Limiting grooves 15 can be provided on both sides of the top of the mounting tube 14, and the introduction tube 16 can be inserted and fixed in the two limiting grooves 15, so as to ensure that the position of the introduction tube 16 is fixed. Furthermore, one end of the introduction tube 16 can be fixedly connected to a limiting block 20, which is clamped with a limiting groove 15 through the limiting block 20; at the same time, a fastening nut 21 can be threadedly connected to the side of the outer surface of the introduction tube 16 away from the limiting block 20. When the two sides of the introduction tube 16 are respectively inserted in the two limiting grooves 15, the end of the limiting block 20 close to the introduction tube 16 is tightly attached to the outer wall of the mounting tube 14, and the fastening nut 21 is rotated at this time, and the fastening nut 21 moves on the outer surface of the introduction tube 16 and is tightly attached to the outer surface of the mounting tube 14, so that the introduction tube 16 is stably inserted in the two limiting grooves 15.

[0030] It should be noted that, when the inlet pipe 16 is installed, the riser 19 is inserted into the mounting pipe 14 and the fixed pipe 5, which facilitates the installation of the distribution pipe 17 and the nozzle 18, and is also very convenient and easy to dismantle during maintenance. At the same time, the mounting pipe 14 and the fixed pipe 5 are connected by the first flange 7, which makes it easy to disassemble the mounting pipe 14 and the fixed pipe 5, thereby reducing the maintenance cost of the device.

[0031] The end of the introduction pipe 16 away from the limit block 20 is installed with a second flange 13, and it can be connected to the water distribution pipe 8 through the second flange 13. The bottom end of the water distribution pipe 8 can also be fixedly connected with a water injection pipe 22, and the lower part of the water injection pipe 22 passes through the top of the water seal groove 4 and extends into the water seal groove 4. Water is introduced into the water injection pipe 22 fixedly connected to it through the water distribution pipe 8, and is introduced into the water seal groove 4 by the water injection pipe 22, so as to realize the water injection of the water seal groove 4. The water injection pipe 22 and the introduction pipe 16 cool down and remove the lime dust entering the water seal groove 4. The outer surface of the lower part of the water injection pipe 22 is fixedly inserted and connected with a mounting block 6, and the mounting block 6 is installed together with the top of the water seal groove 4.

[0032] As can be seen from the above, the water seal tank 4 is arranged on the ground, and a sewage pipe 10 and an overflow pipe 9 are arranged on its outer wall, the sewage pipe 10 and the overflow pipe 9 are introduced into the lime preparation tank 12, and an ash discharge pipe 3 is sealed and installed between the silo body 1 and the water seal tank 4; during the ash unloading work of the silo body 1, the escaped dust in the silo body 1 is introduced into the water seal tank 4 through the ash discharge pipe 3, and the water is introduced into the water injection pipe 22 fixedly connected thereto through the water distribution pipe 8, and then introduced into the water seal tank 4 through the water injection pipe 22, and at the same time, the water distribution pipe 8 will introduce the water into the introduction pipe 16, and then introduce it into the distribution pipe 17 fixedly connected thereto through the introduction pipe 16, and then spray it through the nozzle 18 to further cool down and remove dust; when the ash unloading is completed, the valve 11 is opened as soon as possible, so that the sewage pipe 10 timely introduces the accumulated slag in the water seal tank 4 into the lime preparation tank 12 to prevent blockage caused by excessive accumulation of slag and affect the continuous operation of the lime system.

[0033] When the above-mentioned lime silo dust removal device is in use, it can be sprayed and injected with prepared water, thereby reducing the use of production water. At the same time, the escaping dust can be collected through the overflow pipe 9 and enter the water in the lime preparation tank 12, and finally enter the preparation system, which is conducive to timely recovery of dust and reduces the waste of raw materials. Therefore, the overflow pipe 9 is located above the sewage pipe 10, and the lower end of the water injection pipe 22 can also be located below the overflow pipe 9, so as to form a water seal in the water seal tank 4.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
