Description

Technical Field

[0002] A cyclone dust collector is a type of dust removal device, which consists of an air inlet pipe, an exhaust pipe, a cylinder, a cone and an ash hopper. Its dust removal mechanism is to make the dust-laden airflow rotate, use centrifugal force to separate the dust particles from the airflow and capture them on the wall of the device, and then use gravity to make the dust particles fall into the ash hopper.

[0003] The patent with announcement number CN217190242U discloses a cyclone dust collector, including a cyclone dust collector body, a dust collecting device and a cleaning device. The cyclone dust collector body includes an air inlet pipe, an exhaust pipe, a cylinder, and a cone; the cylinder is connected to the large diameter end of the cone; the dust collecting device is used to collect dust falling during the dust removal process; the cleaning device is used to clean the inner side of the cone; the cleaning device includes an electric push rod, a servo motor, a rotating shaft and a wiping assembly, and the wiping assembly is provided with at least two groups, each group of wiping assemblies includes a telescopic rod and an elastic dust removal strip, and the two sides of the telescopic rod are respectively connected to the rotating shaft and the elastic dust removal strip, and the elastic dust removal strip is always in contact with the inner wall of the cone; the top of the cylinder is provided with a through hole, and the electric push rod can extend into the cylinder through the through hole and connect to the servo motor. The above dust collector can solve the problem that the cone bucket cleaning device of the existing cyclone dust collector cannot automatically achieve complete cleaning of the inner wall of the cone bucket.

[0004] The above-mentioned cyclone dust collector cannot clean the inner wall of the cylinder while removing dust, which may easily lead to long-term accumulation of dust on the inner wall of the cylinder, affecting the dust removal effect. In addition, since the above-mentioned cyclone dust collector cannot prevent the particles from being suspended again, suspended particles will still exist in the air after dust removal, resulting in poor dust removal effect. Utility Model Content

[0005] The utility model aims to provide a cyclone dust collector for drying waste gas, so as to solve the technical problems that dust is easily accumulated in the cleaning cylinder of the existing dust removal equipment and suspended particles are easily formed.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A cyclone dust collector for drying waste gas comprises a support frame, a cone cylinder is fixedly installed inside the support frame, a connecting cylinder is fixedly installed on the upper surface of the cone cylinder, a top cover is fixedly installed on the upper surface of the connecting cylinder, a dust removal mechanism is connected and installed on the upper surface of the top cover, and an air inlet is fixedly installed outside the connecting cylinder, so that the cone cylinder, the connecting cylinder dust removal mechanism and the air inlet form a cyclone dust collector.

[0008] As a further solution of the utility model, a connection box is fixedly installed on the lower surface of the cone, a storage box is slidably installed in the connection box, and the cone is connected to the connection box for dust to be stored in the storage box.

[0009] As a further solution of the utility model, a V-shaped thread strip is arranged on the inner wall surface of the connecting tube, and the opening end of the V-shaped thread strip faces downward.

[0011] As a further solution of the utility model, an impeller is rotatably installed in the air duct, the impeller is driven by a motor fixedly installed on the upper surface, and an air outlet is connected to one end of the air duct.

[0012] As a further solution of the utility model, a sonic vibration cleaner is fixedly mounted on the upper surface of the top cover, and a sonic wave emitting end of the sonic vibration cleaner penetrates to the lower surface of the top cover and is located in the connecting tube.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. When removing dust from drying exhaust gas, the drying exhaust gas can be introduced into the connecting tube from the air inlet. The V-shaped thread can disturb the airflow in the connecting tube, so that the airflow forms a vortex near the inner wall of the connecting tube, effectively enhancing the centrifugal force, causing the dust to be thrown to the connecting tube wall faster, strengthening the collision between the particles and the connecting tube wall, and increasing the contact probability between the particles and the tube wall, so that the dust can be easily settled in the cone tube, so that the settled dust can be prevented from being brought back into the airflow, thereby preventing the particles from being suspended again. The cone tube can guide the dust into the storage box of the connecting box for integrated storage, and the filtered drying exhaust gas will be discharged through the dust removal mechanism.

[0015] 2. When the dry exhaust gas is introduced from the air inlet into the connecting cylinder for dust filtering, the sonic vibration cleaner can be started at the same time to generate vibration on the inner wall of the connecting cylinder, so that it can exert a vibration effect on the particulate matter attached to the wall of the connecting cylinder, and remove the dust and particulate matter from the inner wall of the connecting cylinder, thereby effectively removing the accumulation on the surface of the equipment, including fine dust particles and powder, improving the dust removal effect and cleaning the dust on the surface of the filter, and achieving the effect of cleaning the inner wall of the cylinder.

[0025] See also Figure 1-Figure 2 As shown, an embodiment of the utility model is a cyclone dust collector for drying waste gas, including a support frame 1, a cone cylinder 101 is fixedly installed inside the support frame 1, a connecting cylinder 2 is fixedly installed on the upper surface of the cone cylinder 101, a top cover 201 is fixedly installed on the upper surface of the connecting cylinder 2, a dust removal mechanism 3 is connected and installed on the upper surface of the top cover 201, and an air inlet 202 is fixedly installed outside the connecting cylinder 2, so that the cone cylinder 101, the dust removal mechanism 3 of the connecting cylinder 2 and the air inlet 202 form a cyclone dust collector.

[0026] A connection box 102 is fixedly installed on the lower surface of the cone 101 , and a storage box 103 is slidably installed in the connection box 102 . The cone 101 is connected to the connection box 102 , so that dust can be stored in the storage box 103 .

[0027] A V-shaped thread strip 203 is provided on the inner wall surface of the connecting tube 2, and the open end of the V-shaped thread strip 203 faces downward.

[0028] When removing dust from the drying exhaust gas, the drying exhaust gas is introduced into the connecting tube 2 from the air inlet 202. The V-shaped threaded strip 203 can disturb the airflow in the connecting tube 2, so that the airflow forms a vortex near the inner wall of the connecting tube 2, effectively enhancing the centrifugal force, causing the dust to be thrown toward the wall of the connecting tube 2 faster, strengthening the collision between the particles and the wall of the connecting tube 2, and increasing the contact probability between the particles and the tube wall, so that the dust can be easily settled in the cone tube 101, so that it can prevent the settled dust from being brought back into the airflow, thereby preventing the particles from being suspended again. The cone tube 101 guides the dust into the storage box 103 of the connecting box 102 for integrated storage, and the filtered drying exhaust gas will be discharged through the dust removal mechanism 3.

[0029] like Figure 3-Figure 4 As shown, the dust removal mechanism 3 includes a wind tube 302 and an outlet pipe 304, which are respectively fixedly mounted on the upper surface and the lower surface of the top cover 201, and the wind tube 302 and the outlet pipe 304 are connected, and the outlet pipe 304 is connected to the connecting tube 2.

[0030] An impeller 301 is rotatably installed in the air cylinder 302 , and the impeller 301 is driven by a motor fixedly installed on the upper surface. An air outlet 305 is connected to one end of the air cylinder 302 .

[0031] An acoustic wave vibration cleaner 303 is fixedly mounted on the upper surface of the top cover 201 , and an acoustic wave emitting end of the acoustic wave vibration cleaner 303 penetrates to the lower surface of the top cover 201 and is located in the connecting tube 2 .

[0032] During the process of introducing the dried exhaust gas from the air inlet 202 into the connecting cylinder 2 for dust filtering, the ultrasonic vibration cleaner 303 is simultaneously started to generate vibration on the inner wall surface of the connecting cylinder 2, so that it can exert a vibration effect on the particulate matter attached to the wall of the connecting cylinder 2, and remove the dust and particulate matter from the inner wall of the connecting cylinder 2, effectively removing the accumulation on the surface of the equipment, including fine dust particles and powder, improving the dust removal effect and cleaning the dust on the surface of the filter, thereby achieving the effect of cleaning the inner wall of the cylinder.

[0033] The drying exhaust gas that has undergone dust removal will enter the air duct 302 from the outlet pipe 304, and the impeller 301 arranged in the air duct 302 will be driven to rotate by the motor. The airflow processed by the impeller 301 will be discharged more smoothly from the air outlet 305, which can reduce the pressure loss of the entire system. It not only improves the energy efficiency, but also reduces energy consumption and reduces operating costs. In the process of dust removal, the rotation of the impeller 301 can also generate additional centrifugal force, which further strengthens the separation of particles in the air flow, helps to capture more fine particles, and improves the efficiency of the dust removal system. Negative pressure is generated at the air outlet 305, which helps to enhance the suction force of dust removal, which is particularly effective for treating dust-containing gases with high concentrations and large flows.
