Description

Technical Field

[0001] The present invention relates to the technical field of cupolas, and particularly relates to a cupola for producing rock wool using coal gangue. Background Art

[0002] Rock wool products all use high-quality basalt, dolomite, etc. as the main raw materials. After being melted at a high temperature above 1450 °C, they are centrifuged into fibers at high speed by an internationally advanced four-axis centrifuge. At the same time, a certain amount of binder, dust-proof oil, and water-repellent are sprayed, and then collected by a cotton collecting machine. Through the pendulum method process, after three-dimensional cotton laying, they are cured and cut to form rock wool products of different specifications and uses. In the process of rock wool production, there must be a process of melting raw materials such as rocks through a cupola, so the cupola feeding device came into being.

[0003] Although the existing cupolas can better produce and process rock wool, they often directly add rocks into the cupola. The pre-crushing effect of rocks of different sizes before combustion is not high, reducing the combustion efficiency of larger rocks in the cupola. At the same time, when crushing and feeding rocks, the buffer feeding effect on rocks is not high, easily causing the rocks to directly contact the magma and splash.

When it is necessary to convey rocks into the cupola for combustion processing, in order to improve the crushing effect of rocks with different sizes before combustion and improve the combustion effect of rocks with different sizes in the cupola, the electric push rod 601 is turned on, driving the connecting rod 602 to slide along the inner wall of the limiting groove 604 and driving the swing rod 603 to rotate. The rotation of the swing rod 603 drives the flip plate 606 to move, playing a role in effectively closing the feeding area.

The rotation center of the worm gear 9 is fixedly connected with a crushing roller 10 located above the turning plate 606 through a rotating shaft.

[0035] The swing rod 603 and the cupola body 2 form a rotating structure through the connecting rod 602 and the limiting groove 604. There are two groups of swing rods 603, and the position distributions of the two groups of swing rods 603 are symmetrical about the central axis of the connecting rod 602, which is beneficial to the sliding of the connecting rod 602 along the inner wall of the limiting groove 604, driving the swing rod 603 to rotate along the outer wall of the cupola body 2, and playing a role in driving the relative turning movement of the turning plate 606.

[0036] The turning plate 606 and the cupola body 2 form a turning structure through the connecting rod 602 and the swing rod 603. The turning plate 606 and the swing rod 603 are arranged in a one-to-one correspondence. The turning plate 606 is arranged below the feeding port 4, which is beneficial to the sliding of the connecting rod 602 and the rotation of the swing rod 603 to drive the turning plate 606 to perform a turning movement along the inner side wall of the cupola body 2, and play a role in sealing and crushing rocks of different sizes.

[0037] The connecting box 608 and the cupola body 2 form a lifting structure through the sliding rod 605 and the lifting groove 607. The sliding rod 605 and the connecting rod 602 are integrally connected, which is beneficial to the sliding of the sliding rod 605 along the inner wall of the lifting groove 607, driving the connecting box 608 to slide along the inner wall of the cupola body 2, and playing a role in conveniently adjusting the use height of the crushing roller 10.

[0038] Two groups of helices with opposite rotation directions are arranged on the surface of the worm 8. The crushing roller 10 and the connecting box 608 form a rotating structure through the worm 8 and the worm gear 9. The movement track of the connecting box 608 is set opposite to the movement track of the turning plate 606, which is beneficial to the two groups of helices with opposite rotation directions arranged on the surface of the worm 8 to drive the relative rotation movement of the crushing roller 10, so as to improve the combustion efficiency of the rocks in the cupola.

[0039] The preheating mechanism 11 includes a delivery port 1107. A connecting pipe 1101 is fixedly connected to the outer wall of the cupola body 2. One end of the connecting pipe 1101 is fixedly connected to a heat exchanger body 1102. One end of the heat exchanger body 1102 is fixedly connected to a delivery pipe 1103. One end of the delivery pipe 1103 is fixedly connected to a filter box 1104. A pull rod 1105 is rotatably connected to the outer wall of the connecting rod 602. One end of the pull rod 1105 is rotatably connected to an adjusting plate 1106 that is slidably connected to the bottom of the filter box 1104. A delivery port 1107 is provided at the connection part between the inner side wall of the filter box 1104 and the cupola body 2. When pre-crushing and processing the rock before combustion, in order to improve the synchronous preheating effect of the rock during crushing, through the connection of the connecting pipe 1101, the heat in the furnace body is transported to the inside of the heat exchanger. After heat exchange, through the transportation of the delivery pipe 1103, the heat is transported into the filter box 1104. When driving the connecting rod 602 to move, through the rotational connection of the pull rod 1105, the adjusting plate 1106 is driven to slide along the bottom of the filter box 1104, so that the heat is transported to the crushing area through the delivery port 1107, playing a role in preheating the surface of the crushed rock and improving the combustion efficiency of the rock in the cupola.

[0040] The pull rod 1105 forms a rotational structure between the connecting rod 602 and the adjusting plate 1106. The adjusting plate 1106 forms a lifting structure between the pull rod 1105 and the filter box 1104. The outer wall contour of the adjusting plate 1106 is larger than the outer wall contour of the delivery port 1107, which is beneficial to the sliding of the connecting rod 602. Through the connection of the adjusting plate 1106, the pull rod 1105 is driven to rotate conveniently, playing a role in conveniently adjusting the use state of the delivery port 1107, playing a role in preheating the surface of the crushed rock, and improving the combustion efficiency of the rock in the cupola.

[0041] The protection mechanism 12 includes a protection cover 1202, the outer wall of the furnace liquid delivery track 5 is rotatably connected to the connecting shaft 1201, the outer wall of the connecting shaft 1201 is fixedly connected to the protection cover 1202, one end of the connecting shaft 1201 is fixedly connected to the connecting gear 1203, the outer wall of the furnace liquid delivery track 5 is slidably connected to the telescopic rod 1204, the outer wall of the telescopic rod 1204 is sleeved with a spring 1205 fixedly connected to the outer wall of the furnace liquid delivery track 5, one end of the spring 1205 is fixedly connected to a pull block 1206 fixedly connected to one end of the telescopic rod 1204, and one end of the telescopic rod 1204 is fixedly connected to the connecting gear 1203. The locking rod 1207 that is engaged with the outer wall of the gear 1203 is used to rotate the protective cover 1202 when the furnace liquid needs to be released, in order to reduce the splash-proof effect of the furnace liquid during the release and transportation. The protective cover 1202 is driven to flip over under the connection of the connecting shaft 1201, and the locking rod 1207 is lifted up under the connection of the telescopic rod 1204 and the spring 1205. When the protective cover 1202 stops rotating, the reaction of the spring 1205 being lifted up will cause the locking rod 1207 to engage and fix the connecting gear 1203, thereby improving the stability of the protective cover 1202 in preventing sparks from splashing.

[0042] There are two groups of protective covers 1202, and the positions of the two groups of protective covers 1202 are symmetrical about the central axis of the furnace liquid conveying track 5. The outer wall of the extrusion part of the clamping rod 1207 and the connecting gear 1203 is connected to form an inclined surface, which is beneficial to improving the stability of the protective cover 1202 against sparks and splashes by setting two groups of protective covers 1202 whose positions are symmetrical about the central axis of the furnace liquid conveying track 5.

[0043] Working principle: First, when rocks need to be transported to the cupola for combustion processing, in order to improve the crushing effect of rocks of different sizes before combustion and improve the combustion effect of rocks of different sizes in the cupola, turn on the electric push rod 601, drive the connecting rod 602 to slide along the inner wall of the limit groove 604, and drive the swing rod 603 to rotate. The rotation of the swing rod 603 drives the flip plate 606 to move, which effectively closes the loading area. At the same time, the movement of the flip plate 606 drives the sliding rod 605 to slide along the inner wall of the lifting groove 607, so that the crushing roller 10 moves to the loading track of the loading port 4, and turns on the servo motor 7 to drive the worm gear 9 to rotate through the rotation of the worm 8, and drives the crushing roller 10 to rotate relatively, which plays a role in preliminary crushing of rocks of different sizes.

[0044] Next, when pre-crushing and processing the rock before combustion, in order to improve the synchronous preheating effect of the rock during crushing, the heat in the furnace body is transported into the heat exchanger through the connection of the connecting pipe 1101. After heat exchange, the heat is transported into the filtering box 1104 through the transportation of the transportation pipe 1103. When driving the connecting rod 602 to move, through the rotational connection of the pulling rod 1105, the adjusting plate 1106 is driven to slide along the bottom of the filtering box 1104, so that the heat is transported to the crushing area through the transportation port 1107, playing a role in preheating the surface of the crushed rock and improving the combustion efficiency of the rock in the cupola furnace.

[0045] Finally, when it is necessary to discharge the furnace liquid, in order to reduce the anti-splash effect of the furnace liquid during discharge and transportation, the protective cover 1202 is rotated. Under the connection of the connecting shaft 1201, the protective cover 1202 is driven to perform a flipping motion. Under the connection of the telescopic rod 1204 and the spring 1205, the clamping rod 1207 is lifted. When the protective cover 1202 stops rotating, under the reaction of the spring 1205 being lifted, the clamping rod 1207 will engage and fix the connecting gear 1203, improving the stability of the protective cover 1202 against spark splashing.

[0046] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
