Description

Technical Field

[0001] The utility model belongs to the technical field of silicon ore processing, and particularly relates to a double-stage centrifugal cyclone dust removal device. Background Art

[0002] A large amount of smoke and dust is generated during the production of industrial silicon ore electric furnace. The smoke and dust contains microsilica powder and large particle silicon slag. The microsilica powder can be used for sustainable processing. However, the large particle silicon slag not only has low use value, but also affects the quality (purity of microsilica powder) of the microsilica powder. Moreover, it will cause friction with the impeller of the environmental protection main fan, resulting in wear of the impeller of the environmental protection main fan, short service life, and affecting the continuity of production; the large particle silicon slag will increase the wear of the environmental protection dust removal filter bag, resulting in a high frequency of filter bag replacement and high production cost.

[0003] The utility model patent CN 211706309 U discloses a cyclone dust collector, which includes a barrel-shaped housing. The bottom end of the barrel-shaped housing is fixedly connected with a base. The base is in the shape of a conical funnel. The axis line of the outlet at the bottom end of the base does not coincide with the axis line of the barrel-shaped housing. An air inlet pipe is inserted into the side wall of the base. The top end of the air inlet pipe is fixedly connected with a disc fixed box. A blower is connected inside the disc fixed box. The utility model collects dust in two layers. The dust discharged from the bell mouth will not be disturbed by the gas, which is convenient for falling and collection, thereby reducing the probability of being blown away by the wind and improving the dust removal efficiency.

[0004] Through the cooperation of various components and structures, the above design can efficiently collect the dust generated by the cyclone dust collector by adopting the method of collecting dust in two layers. However, the above design still has some problems. During the operation of the cyclone dust collector, it does not have the effect of preventing blockage, which reduces the functionality of the cyclone dust collector. Summary of the Utility Model

[0005] The purpose of this part is to outline some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this part, as well as in the abstract and the title of the utility model of this application, to avoid obscuring the purpose of this part, the abstract of the specification, and the title of the utility model. However, such simplifications or omissions shall not be used to limit the scope of the utility model.

[0006] To solve the above problems, the utility model adopts the following technical solutions.

[0007] The double-stage centrifugal cyclone dust removal device includes: a base, a cyclone separator, a guide pipe, and a collection bucket. The cyclone separators are symmetrically installed above the base. A guide pipe is fixedly connected to the surface of the outlet pipes of the two cyclone separators, and the top of the guide pipe is connected to the main fan. A collection bucket is slidably installed on the inner wall of the dust collection chamber of the two cyclone separators. A stirring mechanism is fixedly installed on the surface of the cyclone separator to prevent dust blockage.

During the production process of the ferrosilicon furnace, the main fan is started, and the flue dust enters from the inlet pipe of the cyclone separator. The large-particle silicon slag enters the dust collection chamber of the cyclone separator, and the microsilica powder enters the interior of the guide pipe from the outlet pipe of the cyclone separator and is sent to the main fan. The stirring mechanism on the surface of the dust collection chamber of the cyclone separator is started to prevent blockage at the discharge port of the conical part of the cyclone separator.

[0008] As a preferred technical solution of the double-stage centrifugal cyclone dust removal device of the present utility model, a limit block is fixedly connected to the inner wall of the discharge port of the conical part of the cyclone separator. The stirring rod is rotatably connected to the inner wall of the circular hole of the limit block. The linkage rod is rotatably connected to the surface of the conical part of the cyclone separator. The bottom of the stirring rod is meshed with the side of the linkage rod close to the cyclone separator through a bevel gear. A protective shell is fixedly connected to the surface of the dust collection chamber of the cyclone separator. An electric push rod is fixedly connected to the inner wall of the circular groove of the protective shell. The electric push rod in the inner wall of the circular groove of the protective shell retracts and extends reciprocally, driving the linkage rod to rotate. The bevel gear of the linkage rod close to the stirring rod contacts the bevel gear at the bottom of the stirring rod, driving the stirring rod to rotate within the circular hole of the limit block, preventing blockage at the discharge port of the conical part of the cyclone separator.

[0009] As a preferred technical solution of the double-stage centrifugal cyclone dust removal device of the present utility model, a rack is fixedly connected to the surface of the moving end of the electric push rod. A spur gear is fixedly connected to the side of the linkage rod close to the protective shell. The side teeth of the spur gear are meshed with the lower surface teeth of the rack. When the electric push rod retracts and extends reciprocally, the lower surface teeth of the rack contact the side teeth of the spur gear, providing drive for the linkage rod.

Positioning plates are symmetrically fixedly connected to the surface of the collection bucket, and the positioning plates are slidably inserted through the inner walls of the strip-shaped grooves. When the collection bucket enters the interior of the dust collection chamber of the cyclone separator, the positioning plates enter the interior of the strip-shaped grooves, facilitating the collection of large-particle silicon slag. When the collection bucket is removed from the interior of the dust collection chamber of the cyclone separator, the positioning plates slide downward along the inner walls of the strip-shaped grooves to guide the collection bucket.

[0011] As a preferred technical solution of the double - eccentricity cyclone dust removal device of the present utility model, two buckle seats are symmetrically and fixedly connected to the surface of the dust collection chamber of the cyclone separator.

When the collection bucket enters the interior of the dust collection chamber of the cyclone separator, the spring moves the buckle block out of the interior of the rectangular groove of the buckle seat, and the positioning plate enters the inner wall of the rectangular groove of the buckle block to limit the positioning plate, firmly connecting the cyclone separator and the collection bucket.

[0012] As a preferred technical solution of the double - eccentricity cyclone dust removal device of the present utility model, a motor installation groove is provided inside the base. A driving motor is fixedly installed on the inner wall of the motor installation groove. A lifting plate is slidably installed inside the rectangular groove of the base, and the top round rod of the lifting plate is fixedly connected to the bottom of the collection bucket. The output shaft of the driving motor is fixedly connected with a lead screw, and the threaded surface of the lead screw is meshed with the inner wall of the circular hole of the lifting plate. When the driving motor installed on the inner wall of the motor installation groove is started, the output shaft of the driving motor drives the lead screw to rotate. The threaded surface of the lead screw contacts the inner wall of the circular hole of the lifting plate, driving the lifting plate to move upward along the rectangular groove of the base. The lifting plate drives the collection bucket into the interior of the dust collection chamber of the cyclone separator. When the driving motor rotates in the reverse direction, it drives the lifting plate to slide downward along the rectangular groove of the base, moving the collection bucket out of the dust collection chamber of the cyclone separator, facilitating the treatment of the collected large - particle silicon slag.

[0013] As a preferred technical solution of the double - eccentricity cyclone dust removal device of the present utility model, the flank of the stirring rod is made of stainless steel plate. The stainless steel plate has high physical strength and excellent plasticity. When the flank of the stirring rod comes into long - term contact with large - particle silicon slag, the surface will not easily wear, extending the service life of the stirring rod.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] In this utility model, by installing a base, a cyclone separator, a guiding pipe, a collection bucket and a stirring mechanism, the double - cyclone separator design improves the dust removal efficiency. When the cyclone separator filters large - particle silicon slag in the flue dust, it prevents the clogging of the lower feeding port of the conical part of the cyclone separator.
