Description

Technical Field

[0001] The utility model relates to a dust collector, in particular to a cyclone dust collector for industrial waste gas treatment. Background Art

[0002] Cyclone dust collectors are often used to remove particulate matter from industrial waste gas due to their high maintenance rate, low cost and wide range of applicable working conditions. They use spiral centrifugal action to separate gas and solid. The gas rises and is discharged for subsequent treatment, while the solid settles and is collected. However, most of the particulate matter in industrial waste gas is highly oily and viscous. When the discharge port of the cyclone dust collector is relatively slender, it is easy to cause discharge blockage, thereby affecting the normal operation of the cyclone dust collector. Utility Model Content

[0003] In order to solve the deficiencies existing in the above-mentioned technologies, the utility model provides a cyclone dust collector for industrial waste gas treatment.

[0005] A screw feeder is assembled below the coarse-caliber heating discharge mechanism, and the screw feeder has a discharge port;

[0006] The large-caliber heating discharging mechanism includes a large-diameter inner diameter tube, an electric heating wire, an outer cover and a power supply interface;

[0007] The thickened inner diameter tube is welded and fixed at the bottom outlet of the hopper body. The electric heating wire is coiled around the thickened inner diameter tube and connected to the power interface. The power interface is distributed on the outer cover, and the outer cover is arranged outside the thickened inner diameter tube and the electric heating wire.

[0008] Preferably, the cyclone dust collector also includes a spiral feed hopper connected to the feed port.

[0010] Preferably, a mounting ear is welded and fixed on the outer wall of the hopper body.

[0017] The utility model discloses a cyclone dust collector for industrial waste gas treatment. In view of the drawback that solid particles in industrial waste gas are easy to block the traditional elongated discharge port, the opening at the bottom of the hopper body is designed with a larger diameter to connect a large-diameter heating discharge mechanism; the thickened inner diameter pipe in the large-diameter heating discharge mechanism is directly connected to the opening at the bottom of the hopper body, and the thickened pipe diameter design can allow more particles to pass through. At the same time, it has a heating function, which can increase the fluidity of solid particles and reduce the probability of blockage.

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] The utility model discloses a cyclone dust collector for industrial waste gas treatment, the overall structure of which is arranged as follows Figure 1As shown, it includes a hopper body 1, which is the main place for gas-solid separation. A spiral feed hopper 3 is integrally connected to the top of the hopper body 1, and the spiral feed hopper 3 is connected to the feed port 5. Industrial waste gas is fed in through the feed port 5. Under the guidance of the spiral feed hopper 3, the fast-flowing waste gas flows in the hopper body 1 with a spiral characteristic. Under the action of centrifugal force, gas and solid are separated, and the gas rises and is discharged through the exhaust port 4 set on the top of the spiral feed hopper 3 for subsequent processing; the solid particulate matter settles to the bottom of the hopper body 1.

[0023] The present invention is different from the traditional cyclone dust collector in that the opening at the bottom of the hopper body 1 is designed with a larger diameter, which is achieved by raising the setting position of the bottom opening. The specific height increase is designed according to the size of the cyclone dust collector, so that the bottom opening diameter is increased to 1.1 to 1.2 times that of the crude oil.

[0024] As the opening diameter at the bottom of the hopper body 1 increases, the ability to allow particles to pass through is also improved, thereby reducing the probability of outlet blockage. Accordingly, the diameter of the thickened inner diameter tube 16 connected to the bottom outlet of the hopper body 1 will also increase, thereby being more conducive to the smooth passage of settled solid particles.

[0025] The thickened inner diameter tube 16, the electric heating wire 15, the outer cover 6 and the power interface 7 together constitute a thick-diameter heating discharge mechanism; first, the thickened inner diameter tube 16 is welded and fixed at the bottom outlet of the hopper body 1. As mentioned above, the thickened inner diameter tube 16 increases with the increase of the diameter of the bottom opening of the hopper body 1, so that solid particles can pass smoothly. Secondly, an electric heating wire 15 is added, such as Figure 2 As shown, the electric heating wire 15 is coiled around the thickened inner diameter tube 16 and connected to the power interface 7. The electric heating wire 15 is powered on and heated, so that the solid particles are heated during the discharge process. The oily solid particles will have better fluidity under the action of heating, thereby combining the thickened inner diameter tube design to effectively reduce the probability of blockage. The heating temperature of the electric heating wire 15 can be set according to the specific industrial waste gas to be treated. After the electric heating wire is wound and set, a protective outer cover 6 is set on the outer cover of the thickened inner diameter tube 16 and the electric heating wire 15. Correspondingly, the power interface is distributed on the outer cover 6. The power interface can be heat-resistantly protected, for example, the power interface shell is made of high-temperature resistant plastic, and an insulating asbestos board can be wrapped around the shell to play a heat-insulating role.

[0026] Preferably, a screw feeder is assembled below the coarse-caliber heating discharge mechanism, and the screw feeder has a discharge port 12 so that the collected particles can be discharged in a centralized manner by the screw feeder.

[0027] Specifically, the screw feeder includes a horizontally arranged casing 11, a transfer pipe port 14 is arranged on the top of one side of the casing 11, and the transfer pipe port 14 is connected to the thickened inner diameter pipe 16 of the large-diameter heating and discharging mechanism to allow particles to enter the screw feeder.

[0028] The transfer pipe port 14 and the large-caliber heating discharge mechanism are specifically connected through a flange structure. Figure 1 As shown, a lower flange 9 is welded and fixed around the top opening of the transfer pipe port 14; Figure 2 As shown, an upper flange 8 is welded and fixed around the bottom opening of the thickened inner diameter tube 16, a lower flange 9 is fitted and installed with the upper flange 8, and a heat-resistant sealing gasket is sealed between the upper flange 8 and the lower flange 9, so that the screw feeder is assembled and installed below the coarse-diameter heating discharge mechanism.

[0029] A screw feeder for conveying particles is arranged inside the casing 11 of the screw feeder. The shaft of the screw feeder is connected to the reduction motor 10 through a coupling at one end and connected to the bearing seat 13 through a bearing at the other end. The material entering the screw feeder is advanced under the action of the screw feeder and finally delivered at the discharge port 12 at the lower side of the casing 11 of the screw feeder. A collection bucket can be connected to the feeding port 12 to collect the separated solid particles.

[0030] In addition, a mounting ear 2 is welded and fixed on the outer wall of the hopper body 1, and the mounting ear 2 is used for installing the cyclone dust collector on the frame.

[0031] It can be seen from this that the cyclone dust collector for industrial waste gas treatment disclosed in the utility model solves the disadvantage that the existing cyclone dust collector is prone to blockage when the discharge port is relatively slender. The coarse-diameter heating discharge mechanism, through the design of thickening the outlet and combining the heating function, can allow more solid particles to pass through on the one hand, and increase the fluidity of solid particles on the other hand, thereby effectively reducing the probability of blockage.

[0032] The above implementation modes are not limitations of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the technical solution of the present invention also belong to the protection scope of the present invention.
