Description

Technical Field

[0001] The utility model relates to the technical field of cyclone dust collectors, in particular to a built-in pre-filtering cyclone dust collector. Background Art

[0002] Cyclone dust collector is a dust removal device used for high-temperature flue gas treatment generated by the incineration of hazardous waste. It uses the rotating airflow to generate centrifugal force on the flue gas dust to separate it from the airflow. The smallest separated particle can be 5-10um. The cyclone dust collector has a simple structure, low cost, easy maintenance, and can withstand high temperature and high pressure. It can be used for extremely high concentration flue gas dust.

[0003] After searching, the Chinese patent application number CN202320737911.7 discloses a cyclone dust collector, including a cyclone dust collector body, wherein the cyclone dust collector body is provided with an auxiliary dust exhaust component for assisting the cyclone dust collector to discharge dust. However, since the above technical solution does not have a corresponding mechanism for pre-filtering the airflow entering the dust collector, there is still a problem that larger particles and metal debris in the airflow are easily directly sucked into the dust collector, causing damage to the internal structure of the dust collector, thereby affecting the service life of the dust collector. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a built-in pre-filtering cyclone dust collector.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A built-in pre-filtering cyclone dust collector comprises a cylindrical portion, an air inlet is arranged on the outer wall of one side of the cylindrical portion, a second filter is inserted into the inner wall of one side of the air inlet, a handle is fixed to the outer wall of one side of the second filter, a discharge port is opened on the outer wall at the bottom of the air inlet, a collection box is arranged on the outer wall at the bottom of the discharge port, a rotating shaft is rotatably connected to the inner wall of the air inlet, a plurality of fan blades are fixed to the outer wall of the rotating shaft, and an elastic block is fixed to the outer wall of the fan blades.

[0007] As a further solution of the utility model: the outer wall at the bottom of the cylindrical part is provided with a cone part, the outer wall at the bottom of the cone part is provided with a dust collecting box, and the outer wall at the top of the cylindrical part is plugged with an outlet pipe.

[0008] As a further solution of the utility model: a rectangular through groove is formed on the outer wall of the air inlet, a magnet sheet is inserted into the inner wall of the rectangular through groove, and a connecting plate is fixed to the outer wall of the magnet sheet.

[0009] As a further solution of the utility model: a plurality of fixing plates are fixed to the outer wall of the handle, and the fixing plates are fixed to the outer wall of the air inlet by screws.

[0012] As a further solution of the utility model: a plurality of pulleys are fixed to the outer wall of the bottom of the bracket.

[0013] As a further solution of the utility model: the inner wall of the outlet pipe is connected with a threaded pipe through a thread, a connecting sleeve is fixed to the outer wall of the threaded pipe, and a first filter screen is arranged on the inner wall of the connecting sleeve.

[0014] The beneficial effects of the utility model are:

[0015] 1. When the cyclone dust collector is running, the external airflow will enter the interior of the cylinder through the air inlet. At this time, the second filter screen inserted in the air inlet can pre-filter the airflow passing through the air inlet and entering the interior of the cylinder, preventing larger particles in the external airflow from entering the interior of the cylinder through the air inlet. At the same time, the airflow passing through the air inlet will blow the fan blades and the shaft to rotate. The rotating fan blades will continuously hit the outer wall of the second filter screen through the elastic blocks on the outer wall, causing the second filter screen to shake, allowing the dust and particulate matter filtered out on the outer wall of the second filter screen to fall into the discharge port, and then enter the inner wall of the collection box for temporary storage, thereby pre-filtering the airflow entering the cylinder for dust removal, thereby increasing the service life of the dust collector and facilitating the staff to recycle the dust particles at the pre-filtered location.

[0016] 2. The magnet sheet can absorb the metal debris in the air flow passing through the air inlet, thereby improving the pre-filtration effect. The staff can regularly pull the magnet sheet out from the inner wall of the rectangular through groove through the connecting plate to recover the metal debris absorbed on the magnet sheet.

[0017] 3. The first filter can filter the gas discharged through the outlet pipe, and at the same time shield and protect the outlet pipe to prevent external dust from falling into the cylinder through the outlet pipe; the support rod and the bracket can support the dust collector as a whole, and the dust collector can be conveniently pushed to move through the pulley.

[0026] When the cyclone dust collector is running, the external airflow will enter the interior of the cylinder 1 through the air inlet 13. At this time, the second filter 16 inserted in the air inlet 13 can pre-filter the airflow that passes through the air inlet 13 and enters the interior of the cylinder 1, preventing larger particles in the external airflow from entering the interior of the cylinder 1 through the air inlet 13. At the same time, the airflow passing through the air inlet 13 will blow the fan blades 17 and the rotating shaft 14 to rotate. The rotating fan blades 17 will continuously hit the outer wall of the second filter 16 through the elastic blocks 11 on the outer wall, thereby causing the second filter 16 to shake, allowing the dust and particulate matter filtered out on the outer wall of the second filter 16 to fall into the discharge port 23, and then enter the inner wall of the collection box 22 for temporary storage, thereby filtering the airflow that enters the interior of the cylinder 1 for dust removal in advance, thereby increasing the service life of the dust collector and facilitating the staff to recycle the dust particles at the pre-filtered location.

[0027] like Figure 2-3 As shown, a rectangular through groove 18 is formed on the outer wall of the air inlet 13, a magnet sheet 15 is inserted into the inner wall of the rectangular through groove 18, and a connecting plate 20 is fixed to the outer wall of the magnet sheet 15; the magnet sheet 15 can adsorb metal debris in the air flow passing through the air inlet 13, thereby improving the pre-filtration effect, and the staff can regularly pull the magnet sheet 15 out of the inner wall of the rectangular through groove 18 through the connecting plate 20 to recover the metal debris adsorbed on the magnet sheet 15.

[0028] like Figure 3 As shown, a plurality of fixing plates 19 are fixed to the outer wall of the handle 21, and the fixing plates 19 are fixed to the outer wall of the air inlet 13 by screws; an air guide cover 12 is fixed to the outer wall of the air inlet 13; after the staff holds the handle 21 and inserts the second filter 16 into the air inlet 13 from one side of the air inlet 13, the fixing plates 19 can be fixed to the one side of the air inlet 13 by screws, thereby fixing the second filter 16 as a whole.

[0029] like Figure 1 As shown, a group of support rods 2 are fixed to the outer wall of the cylindrical part 1, and a bracket 5 is fixed to the outer wall at the bottom of the support rod 2; a plurality of pulleys 4 are fixed to the outer wall at the bottom of the bracket 5; the support rods 2 and the bracket 5 can support the dust collector as a whole, and the dust collector can be conveniently pushed to move through the pulley 4.

[0030] Working principle: When the cyclone dust collector is running, the external airflow will enter the interior of the cylindrical part 1 through the air inlet 13. At this time, the second filter 16 inserted in the air inlet 13 can pre-filter the airflow passing through the air inlet 13 and entering the interior of the cylindrical part 1, thereby preventing larger particles in the external airflow from entering the interior of the cylindrical part 1 through the air inlet 13. At the same time, the airflow passing through the air inlet 13 will blow the fan blades 17 and the rotating shaft 14 to rotate. The rotating fan blades 17 will continuously hit the outer wall of the second filter 16 through the elastic blocks 11 on the outer wall, thereby causing the second filter 16 to shake, allowing the dust and particulate matter filtered out on the outer wall of the second filter 16 to fall into the discharge port 23, and then enter the inner wall of the collection box 22 for temporary storage, thereby filtering the airflow entering the interior of the cylindrical part 1 for dust removal in advance, thereby increasing the service life of the dust collector.

[0031] The magnet sheet 15 can absorb metal debris in the air flow passing through the air inlet 13, thereby improving the pre-filtration effect. The staff can regularly pull the magnet sheet 15 out from the inner wall of the rectangular through groove 18 through the connecting plate 20 to recover the metal debris absorbed on the magnet sheet 15.
