[0027] Embodiment 1:

[0028] Refer to Figure 1 , a dust treatment and dust removal device disclosed by the present utility model, comprising a sandblasting room 1, a sedimentation tank 2, a cyclone dust collector 3, a filter element dust collector 4, and a high-pressure blower 5 connected in sequence through an air duct, and a discharge chimney 6 is installed on the air duct between the high-pressure blower 5 and the filter element dust collector 4.

[0029] There is a workpiece in the sandblasting room 1. After being processed by the equipment in the sandblasting room 1, the dust generated is adsorbed through the air duct and enters the sedimentation tank 2 to treat large-particle dust, passes through the cyclone dust collector 3 to treat small-particle dust, passes through the filter cartridge dust collector 4 to treat fine dust, and finally is discharged through the exhaust chimney 6 to complete the entire dust treatment and discharge process.

[0030] The cyclone dust collector 3 is a multi-tube ceramic cyclone dust collector. The original cyclone dust collector used iron castings. After long-term use, the iron products would rust and block the internal channels and could not be used. Now it is replaced with ceramic cyclone pipes, which can effectively solve the above problems. It has good effects, a long service life, low cost, and is economical and practical.

[0031] The ceramic dust collector is a cyclone type dust collector. When the dust-containing gas enters the dust collector and passes through the ceramic guide, it rotates at a high speed inside the cyclone tube. Under the action of centrifugal force, the dust and gas are separated. The dust falls into the dust collection box 32 and is discharged through the ash discharge valve; the purified gas forms an upward swirling flow, converges in the gas collection chamber through the exhaust pipe, and is discharged through the air duct at the outlet to achieve the dust removal effect; through high wind speeds, the coarser dust particles are separated from the fine dust by the resistance friction and gravity sedimentation functions on the inner wall. The ceramic multi-tube cyclone dust collector 3 has the advantages of corrosion resistance, wear resistance, high temperature resistance, non-blocking, long service life, simple operation and management, no cost, and no secondary pollution.

[0032] A first sand collection bucket 21 for collecting large-particle sand is provided below the sedimentation tank 2. Multiple second sand collection buckets 31 for collecting small-particle sand are provided at the bottom of the cyclone dust collector 3. The cyclone dust collector 3 includes a dust collection box 32 and a plurality of ceramic tubes 33 provided above the dust collection box 32. The second sand collection bucket 31 is provided below the dust collection box 32. In this embodiment, referring to Figure 3 , the ceramic tube 33 is made of earth products mixed with special materials and cast and fired, and has the advantages of corrosion resistance, wear resistance, high temperature resistance, non-blocking, long service life, and low cost.

[0033] Multiple dust collection buckets 41 for collecting dust are provided at the bottom of the filter cartridge dust collector 4. A plurality of filter cartridges 42 are installed inside the filter cartridge dust collector 4. The filter cartridges 42 are made of peritoneal polyester fiber materials, and wrinkles are provided on the outer surface of the filter cartridges 42 (see Figure 4 ). The filter cartridges 42 are made of high-quality peritoneal polyester fiber materials, and their characteristics are small volume. Because of the wrinkles, they can well adhere to the dust and are not corroded, and can be cleaned and used repeatedly.

[0034] The filter cartridge dust collector 4 is composed of multiple filter cartridges 42, pulse valves, air blowing pipes, etc. and is suitable for working in a negative pressure device to avoid air pollution and is also suitable for production operations; the filter cartridges 42 of the dust collector will be automatically cleaned in turn. While one or several filter cartridges 42 stop working for a short period of time, the other filter cartridges 42 continue to work. The cleaning process depends on the type and quantity of the dust to be removed; in the normal working state, the dusty air passes through the inlet of the dust collector, and the dust is collected outside the dust removal filter cartridge.

[0035] The air in the filter cartridge 4 enters the clean air chamber through a thin pipe and is discharged from the opening at the outlet end. The dust-removing filter cartridge will be automatically cleaned; compressed air is blown into the interior of the filter cartridge 42 and acts on the dust removal components. The collected dust bounces off the filter cartridge from the outside of the dust removal filter cartridge 42 and falls into the dust collector; the filter cartridge is vertically installed from top to bottom, and the installation is simple and convenient. Refer to Figure 2 On the filter cartridge dust collector 4, an air inlet and an air outlet are provided, and valves are respectively installed on the air inlet and the air outlet.

[0036] For the treatment of the original sandblasting dust, a bag filter or directly extracting it with a fan into water was used. Due to the long length of the bag filter cartridge 42, the carrier volume was large, the cost was high, and the dust treatment effect was poor. Subsequently, this dust removal method was gradually cancelled and replaced with the current filter cartridge 42 made of high-quality polyester fiber with a film, which has good effects, a long service life, low cost, and is economical and practical.

[0037] The implementation principle of the present utility model is as follows: The dust treatment and dust removal equipment of the present utility model has three treatment processes in total: the first is that the sedimentation tank 2 treats large particles and is centrally collected by the first sand collection bucket 21, the second is that the multi-tube ceramic cyclone dust collector 3 treats small particles and is centrally collected by the second sand collection bucket 31, and the third is that the filter cartridge dust collector 4 treats fine dust and is centrally collected by the ash collection bucket 41. The waste gas after the first three treatments can be directly discharged into the atmosphere, meeting the requirements of the Comprehensive Emission Standard for Air Pollutants.

[0038] The embodiments of the present specific implementation manners are all preferred embodiments of the present utility model, and do not limit the protection scope of the present utility model accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present utility model should be covered within the protection scope of the present utility model.
