Description

Technical Field

[0001] This utility model relates to the field of centrifugal heat exchange technology, and in particular to an electrically controlled telescopic flow guiding device for centrifuges used in rock wool production. Background Technology

[0002] Rock wool products are fireproof and energy-saving insulation materials made from natural rocks as the main raw material. They are produced by high-temperature melting in a melting furnace, fiberization and sizing, felt board curing and molding, and post-processing. Rock wool products are widely used in construction, petroleum, chemical, metallurgy, agriculture and other industries due to their excellent heat insulation, fire resistance and sound insulation and absorption properties.

[0003] Currently, centrifuges used for separating rock wool raw materials require temperature regulation and heat exchange during use. The current heat exchange method involves setting up a heat exchange mechanism on the outside to adjust the heat at the centrifuge position. This method is not only inefficient in terms of temperature regulation and heat exchange, but also cannot perform rapid temperature regulation of the centrifuge surface. Utility Model Content

[0004] The technical problem this invention aims to solve is that current temperature control systems are inefficient and cannot perform rapid temperature control on centrifugal surfaces.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an electrically controlled telescopic flow guiding device for centrifuges used in rock wool production, including an annular assembly frame, an external flow guiding pipe and an external return pipe fixedly assembled on the side wall of the annular assembly frame, a lateral flow guiding shroud slidably assembled on the outside of the annular assembly frame, the outer surface of the lateral flow guiding shroud having an inwardly bent arc-shaped external flow guiding shroud, an annular internal flow guiding groove connected to the external flow guiding pipe and an annular external return groove connected to the external return pipe are opened inside the lateral flow guiding shroud, a lateral isolation ring is fixed on the inner wall of the lateral flow guiding shroud by a lateral bracket, and an electrically controlled drive unit is installed between the annular assembly frame and the lateral flow guiding shroud.

[0006] A lateral compression sealing ring is elastically fitted on the outer surface of the lateral isolation ring.

[0007] An annular assembly groove for assembling a side fairing is provided on the outer side of the annular assembly frame, and an embedded adjusting support rod for controlling the side fairing is installed on the inner side of the annular assembly groove.

[0008] An annular control groove for installing an electronically controlled drive unit is provided on the inner arc-shaped surface of the annular assembly groove, and an annular toothed groove for cooperating with the electronically controlled drive unit is provided on the inner assembly surface of the lateral guide shield.

[0009] The electronically controlled drive unit includes a ring motor installed inside the ring control slot and a drive gear ring installed on the outer drive ring of the ring motor.

[0010] The inner arc-shaped surface of the arc-shaped outer shroud has an integrally structured drive blade.

[0011] The beneficial effects of this utility model are:

[0012] (1) The electrically controlled telescopic flow guiding device for centrifuges used in rock wool production of this utility model adopts an electrically controlled telescopic structure design, which can adjust the opening and closing state between it and the centrifugal roller as needed, making it convenient for cooperation and subsequent maintenance;

[0013] (2) By directly introducing the heat exchange fluid into the heat exchange channel inside the centrifugal roller, and then quickly drawing it back through centrifugal action, the heat exchange efficiency is greatly improved.

[0014] (3) By using a lateral expansion and compression method for cooperation, and by setting a lateral isolation ring on the side wall of the lateral guide shield, the airtightness between the inlet and the return flow can be greatly improved. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] Figure 1 , Figure 2 and Figure 3The illustrated electrically controlled telescopic flow guiding device for centrifuges used in rock wool production includes an annular assembly frame 1. An external flow guiding pipe 2 and an external return pipe 3 are fixedly mounted on the side wall of the annular assembly frame 1. A lateral flow guiding shroud 4 is slidably mounted on the outside of the annular assembly frame 1. The outer surface of the lateral flow guiding shroud 4 has an inwardly bent arc-shaped external flow guiding shroud 5. The interior of the lateral flow guiding shroud 4 has an annular internal flow guiding groove 6 connected to the external flow guiding pipe 2 and an annular external return groove 7 connected to the external return pipe 3. A lateral isolation ring 8 is fixed to the inner wall of the lateral flow guiding shroud 4 by a lateral bracket. An electrically controlled drive unit is installed between the annular assembly frame 1 and the lateral flow guiding shroud 4.

[0022] Working principle: A heat exchange channel is first opened inside the centrifugal roller of the centrifuge for direct temperature control of the centrifugal roller. The return port of the heat exchange channel is located on one side of the outer arc-shaped surface and cooperates with the arc-shaped external guide shroud 5. The inlet of the heat exchange channel is located on one side and cooperates with the side guide shroud 4. The external guide pipe 2 guides the flow into the inlet of the heat exchange channel through the side guide shroud 4, and then returns from the return port of the heat exchange channel to the arc-shaped external guide shroud 5. Finally, the flow returns from the side guide shroud 4 to the external return pipe 3 through the arc-shaped external guide shroud 5.

[0023] To facilitate lateral sealing, a lateral compression sealing ring 9 is elastically fitted on the outer surface of the lateral isolation ring 8.

[0024] The lateral isolation ring 8 has an annular expansion groove on its extrusion surface. The lateral extrusion sealing ring 9 includes a lateral extrusion ring inserted into the annular expansion groove and an extrusion spring located between the lateral extrusion ring and the annular expansion groove.

[0025] To reduce friction, replaceable embedded anti-wear pads are installed on the extrusion surface of the lateral extrusion ring, which can improve lubrication while ensuring sealing.

[0026] For sliding adjustment, an annular assembly groove for assembling the side guide shroud 4 is provided on the outer side of the annular assembly frame 1, and an embedded adjustment support rod 10 for controlling the side guide shroud 4 is installed on the inner side of the annular assembly groove.

[0027] The extended end of the embedded adjusting strut 10 is fixed with a linkage ring that is movably assembled with the side fairing 4. The linkage ring can control the sliding of the side fairing 4 without affecting its rotation.

[0028] To accommodate this, an annular control groove for mounting the electronically controlled drive unit is provided on the inner arc-shaped surface of the annular assembly groove, and an annular toothed groove 11 for cooperating with the electronically controlled drive unit is provided on the inner assembly surface of the side guide shroud 4.

[0029] To facilitate the drive, the electronically controlled drive unit includes a ring motor 12 installed inside the ring control slot and a drive gear ring 13 installed on the drive ring outside the ring motor 12.

[0030] The embedded adjustment strut 10 slides the side guide 4 on the annular assembly groove by telescopic adjustment. When the side guide 4 is pressed outward until the drive gear ring 13 meshes with the annular gear groove 11, the wake-up motor 12 can drive the side guide 4 to rotate at high speed through the drive gear ring 13.

[0031] To improve the efficiency of the outer return flow, the inner arc-shaped surface of the arc-shaped outer guide shroud 5 has an integrated drive blade 14.

[0032] While the arc-shaped external guide shroud 5 drives the drive blades 14 to rotate at high speed, the heat exchange liquid located at the position of the arc-shaped external guide shroud 5 will be quickly drawn into the side guide shroud 4, and then flow back to the external return pipe 3 from the annular external return groove 7 through the side guide shroud 4.

[0033] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
