Description

Technical Field

[0001] The invention relates to the technical field of zircon sand conveying and guiding, in particular to a pneumatic multi-material guiding mechanism applied to a zircon sand conveyor. Background Art

[0002] Zircon sand, also known as zircon sand and zircon stone, is a mineral mainly composed of zirconium silicate. Zircon stone is mainly composed of zirconium, silicon and oxygen crystallized from magma during the formation of igneous rocks. It is a high-quality refractory material. It is often found in coastal sand with ilmenite, rutile, monazite, xenotime and other minerals, and is obtained after separation by water separation, electric separation, magnetic separation and other mineral separation processes. Zircon sand has a wide range of applications in the fields of casting, materials and chemical industries.

[0003] Due to structural limitations, zircon sand is mostly transported and discharged pneumatically during transportation. During the transport and discharge process, the current conveying pipelines are mostly single-pipe designs. When switching and adjusting the internal conveying sand, only multiple elbows can be assembled. The elbows at different positions are used to guide the internal sand. However, this material guiding method is not only cumbersome to control in the later stage, but also increases the resistance of internal material guiding. After switching, some residual material will remain in the material guiding pipeline. At the same time, it is impossible to guarantee the flow stability when multiple pipelines are switched at the same time, and the efficiency of intelligent conveying control is not high. Summary of the invention

[0004] The technical problem to be solved by the present invention is that the current material guiding method of the material conveying pipeline is not only cumbersome to control in the later stage, but also increases the resistance of the internal material guiding. After switching, some residual material will remain inside the material guiding pipeline.

[0006] The lateral shunt pipe includes a central adjustment cover shell with lateral assembly pipes extending to both sides. The central adjustment cover shell is axially fixedly connected with the first feed pipe and the second feed pipe at the connecting end of the first feed pipe and the second feed pipe through lateral assembly pipe sleeves at both ends.

[0009] The inner wall of the lateral assembly tube is provided with inner telescopic openings for installing the built-in electric control opening and closing cover at positions corresponding to the lateral material guide bosses and the longitudinal material guide bosses.

[0010] The built-in electric-controlled opening and closing cover comprises an arc-shaped closing cover plate inserted in the inner telescopic opening and a lateral telescopic support rod fixed on the outer arc-shaped surface of the lateral assembly tube.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] Figure 1 , Figure 2 , Figure 3 and Figure 4 A pneumatic multi-direction material guiding mechanism applied to a zircon sand conveyor is shown, comprising a main conveying pipeline for conveying zircon sand particles, the main conveying pipeline comprising a first conveying pipe 1 and a second conveying pipe 2, a lateral diverter pipe 3 is axially fixed between the first conveying pipe 1 and the second clinker pipe 2, an electrically-controlled lateral material guiding mechanism 4 is movably mounted on the outer surface of the lateral diverter pipe 3, an electrically-controlled centrifugal distribution module 5 is movably mounted inside the lateral diverter pipe 3, a built-in electrically-controlled opening and closing cover 6 is installed inside the lateral diverter pipe 3 and located inside the electrically-controlled centrifugal distribution module 5, and an external electrically-controlled opening and closing cover 7 is installed inside the electrically-controlled lateral material guiding mechanism 4.

[0024] Zircon sand driven by high-pressure air is introduced through the first feed pipe 1, and then introduced into the lateral diversion pipe 3. The built-in electric-controlled opening and closing cover 6 and the external electric-controlled opening and closing cover 7 need to be opened. At this time, the sand and air inside the lateral diversion pipe 3 will not only be introduced into the second feed pipe 2, but also can be introduced into the electric-controlled lateral material guide mechanism 4 through the electric-controlled centrifugal distribution module 5, and then used The electric-controlled lateral material guide mechanism 4 is used to introduce it outward into the designated material guide pipe.

[0025] In order to cooperate with the assembly connection, the lateral diversion pipe 3 includes a central adjustment cover 32 with a lateral assembly pipe 31 extending to both sides. The central adjustment cover 32 is axially fixedly connected with the first material delivery pipe 1 and the second material delivery pipe 2 through the lateral assembly pipes 31 at both ends.

[0026] Annular sleeve grooves for sleeve-fixing the first and second material delivery pipes 1 and 2 are provided on both sides of the lateral assembly pipe 31 , and lateral assembly bolts for locking the first and second material delivery pipes 1 and 2 are threadedly assembled on the outer side of the lateral assembly pipe 31 .

[0027] In order to cooperate with the electrically controlled material guiding, the electrically controlled lateral material guiding mechanism 4 includes a lateral material guiding boss 41 fixed on the side wall of the central adjusting cover 32, a longitudinal material guiding boss 42 fixed on the side wall of the central adjusting cover 32, a first flip material guiding tube 43 movably mounted on the lateral material guiding boss 41, a first electrically controlled support rod 44 for controlling the first flip material guiding tube 43, a second flip material guiding tube 45 movably mounted on the longitudinal material guiding boss 42 and a second electrically controlled support rod 46 for controlling the second flip material guiding tube 45.

[0028] The first electrically controlled support rod 44 adjusts the angle of the first overturning material guiding tube 43 by extending and retracting, and the second electrically controlled support rod 46 adjusts the angle of the second overturning material guiding tube 45 by extending and retracting.

[0029] The first inverted material guiding tube 43 and the second inverted material guiding tube 45 are used for connecting to an external material delivery pipeline.

[0030] In order to cooperate with the lateral material guiding, the electrically controlled centrifugal distribution module 5 includes an annular adjustment frame 51 movably installed inside the central adjustment cover 32, centrifugal material guiding blades 52 fixedly installed inside the annular adjustment frame 51, an adjustment motor 53 fixed on the side wall of the central adjustment cover 32, and a transmission gear set 54 for transmitting and connecting the annular adjustment frame 51 and the adjustment motor 53.

[0031] There is an annular tooth groove on the outer arc surface of the annular adjustment frame 51, and the transmission gear set 54 includes a first gear meshing with the annular tooth groove and a second gear axially fixed on the adjustment shaft of the adjustment motor 53. The first adjustment gear and the second gear mesh with each other for transmission.

[0032] In order to cooperate with the opening and closing control, the inner wall of the lateral assembly tube 31 corresponding to the lateral material guide boss 41 and the longitudinal material guide boss 42 is provided with an inner telescopic opening for installing the built-in electric control opening and closing cover 6.

[0033] In order to control the inner telescopic opening, the built-in electric control opening and closing cover 6 includes an arc-shaped closing cover plate 61 inserted into the inner telescopic opening and a lateral telescopic support rod 62 fixed on the outer arc surface of the lateral assembly tube 31 .

[0034] The lateral telescopic support rod 62 controls the arc-shaped closed cover plate 61 to extend and retract inside the inner telescopic opening. When the lateral telescopic support rod 62 extends, it controls the arc-shaped closed cover plate 61 to extend into the lateral assembly tube 31, thereby opening the inner telescopic opening. At this time, the air and sand and gravel in the lateral assembly tube 31 can be introduced into the middle adjustment cover shell 32 from the inner telescopic opening.

[0035] In order to cooperate with the internal closed seal, the inner side surfaces of the lateral material guiding protrusion 41 and the longitudinal material guiding protrusion 42 are provided with an internal sealing ring 8 that cooperates with the externally mounted electric control opening and closing cover 7.

[0036] In order to cooperate with the opening and closing control of the internal connection state of the lateral material guide boss 41 and the longitudinal material guide boss 42, the external electrically controlled opening and closing cover 7 includes an internal sealing cover plate 71 arranged on the outside of the internal sealing ring 8 and an external telescopic support rod 72 fixed on the outer wall of the first flip material guide tube 43 and the second flip material guide tube 44.

[0037] The external telescopic support rod 72 controls the internal sealing cover plate 71 to be adjusted by extension and retraction. When the external telescopic support rod 72 controls the internal sealing cover plate 71 to be squeezed inward on the internal sealing ring 8 by extension, the lateral material guide boss 41 and the inside of the lateral assembly tube 31 or the longitudinal material guide boss 42 and the inside of the lateral assembly tube 31 are closed.

[0038] In order to monitor the pressure at different positions, pressure sensor modules 9 for controlling the electrically controlled centrifugal flow distribution module 5 are fixed on the surface of the arc-shaped closed cover plate 61 adjacent to the lateral assembly tube 31 and on the surface of the internal sealing cover plate 71 .

[0039] By comparing the pressure inside the lateral assembly tube 31, the pressure inside the lateral material guide boss 41 and the pressure inside the longitudinal material guide boss 42, the speed of the regulating motor 53 is changed according to the pressure difference, so that the lateral material guide boss 41 and the longitudinal material guide boss 42 can maintain sufficient material guide pressure; Working principle: before the material guiding needs to be adjusted, the pressure sensor module 9 located on the arc-shaped closed cover plate 61 will pre-detect the set material feeding pressure inside the pipeline. Then, during material guiding, the arc-shaped closed cover plate 61 extends into the lateral assembly tube 31. At this time, as the annular adjustment frame 51 drives the centrifugal material guiding blades 52 to rotate, the air inside the lateral assembly tube 31 is drawn into the inner telescopic opening, and then introduced into the lateral material guiding boss 41 or the longitudinal material guiding boss 42. When the pressure inside the lateral material guiding boss 41 or the longitudinal material guiding boss 42 is lower than the pressure inside the lateral assembly tube 31, it is necessary to drive the centrifugal material guiding blades 52 to rotate quickly by adjusting the motor 53, thereby increasing the lateral material guiding pressure and ensuring the material guiding efficiency.

[0040] In order to adjust and cut off the flow of the lateral opening, an electrically controlled material guiding closing valve 10 is movably installed at one end of the lateral assembly pipe 31 .

[0041] The use of a horizontal butterfly valve for rotation adjustment can reduce the impact on the resistance in the lateral assembly tube 31 when idle. The control method is to install a worm gear assembly on the outside of the lateral assembly tube 31, and then use an assembly shaft on one side of the valve to penetrate the lateral assembly tube 31 and the worm gear axial transmission inside the worm gear assembly, and drive the worm gear to rotate through the electrically controlled worm, thereby synchronously controlling the valve for angle adjustment.

[0042] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
