Description

[0002] A type of inorganic non-metallic material with a refractoriness of not less than 1580℃. Refractoriness refers to the Celsius temperature at which a conical specimen of a refractory material can resist high temperature without softening and melting under no load. However, the definition of refractoriness alone can no longer fully describe refractory materials. 1580℃ is not absolute. It is now defined as any material whose physical and chemical properties allow it to be used in a high temperature environment. Refractory materials are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate, power and other industrial fields. The largest amount is used in the metallurgical industry, accounting for 50% to 60% of the total output. After forming, tubular refractory materials need to be polished to remove burrs for easy use.

A connecting rod 312 penetrating the turntable 35 is provided on one side of the adjusting disk 39. A slide plate 34 is fixed at one end of the connecting rod 312. One end of the slide plate 34 slides on the rotating shaft 33, and the other end of the slide plate 34 slides on the rotating shaft 33. A measuring rod 36 slides on one end; the adjusting disk 39 drives the grinding assembly 37 to grind the inner wall of the tubular refractory material while sliding on the turntable 35.

At the same time, the adjusting disk 39 drives the slide plate 34 to move by the connecting rod 312, and the slide plate 34 drives the measuring rod 36 to move, so that one side of the measuring rod 36 contacts and slides with the outer side of the tubular refractory material. In addition, during the rotation of the rotating shaft 33, the rotating shaft 33 drives the adjusting disk 39 to rotate through the turntable 35, and the adjusting disk 39 drives the grinding assembly 37 to rotate During the process, the grinding assembly 37 grinds the inner wall of the tubular refractory material; a motor c32 is fixed to one side of the fixed frame 31, and the output end of the motor c32 is fixedly connected to the rotating shaft 33, a transition ring 313 is provided on the rotating shaft 33, the transition ring 313 is slidably connected to the slide plate 34, a scale is provided on the slide plate 34, a bolt a connected to the transition ring 313 is provided on the slide plate 34, one end of the rotating shaft 33 is fixedly connected to the rotating disk 35, a rubber ring a is provided on the outer side of the rotating disk 35, a limiting groove 38 for sliding of the adjusting disk 39 is provided on the rotating disk 35, and a setting is provided on the adjusting disk 39 There is a bolt b fixed with the limiting groove 38, a roller a310 is arranged on one side of the adjusting disk 39, and the roller a310 is slidably connected with the inner wall of the tubular refractory material, the grinding assembly 37 includes a motor b and a grinding disk, the motor b is fixedly installed on the adjusting disk 39, the connecting rod 312 penetrates the rotating disk 35 and slides on the limiting groove 38, one end of the connecting rod 312 is fixedly connected with the slide plate 34, one end of the measuring rod 36 is installed with a roller b311, and the roller b311 is slidably connected with the outer side of the tubular refractory material, and the other end of the measuring rod 36 is damped and slid on the slide plate 34;

[0030] See also Figures 3 to 8 As shown, before grinding, an adjusting disk 39 is slid on the turntable 35, and the adjusting disk 39 drives the grinding assembly 37 to move. According to the size of the tubular refractory material, the position of the grinding assembly 37 is flexibly adjusted so that the grinding disk on the grinding assembly 37 can grind the inner wall of the tubular refractory material. After the adjustment is completed, the adjusting disk 39 and the limiting groove 38 can be fixed by bolts b to make it stable. After the motor C32 is started, the output end of the motor C32 drives the rotating shaft 33 to rotate, and the rotating shaft 33 drives the turntable 35 to rotate. The turntable 35 rotates through the adjusting disk 39, and the adjusting disk 39 drives the grinding assembly 37 to rotate. During the rotation of the grinding assembly 37, the inner wall of the tubular refractory material can be ground, thereby automatically grinding the inner wall of the tubular refractory material, reducing manual grinding, and the precision of automatic grinding is higher, thereby improving the accuracy of grinding the inner wall of the tubular refractory material.

[0031] When adjusting the adjusting disk 39, the roller a310 on one side of the adjusting disk 39 is in contact with the inner wall of the tubular refractory material, and the adjusting disk 39 drives the connecting rod 312 to move, and the connecting rod 312 drives the slide plate 34 to move, and the slide plate 34 slides on the transition ring 313. The adjustment range of the adjusting disk 39 can be visually checked through the scale on the slide plate 34, thereby helping the group to adjust the position of the grinding assembly 37; at the same time, after the adjustment of the slide plate 34 is completed, the slide plate 34 is provided with a bolt a connected with the transition ring 313, which can assist in fixing the slide plate 34 with the transition ring 313, so that the slide plate 34 can rotate with the rotating shaft 33 during the rotation of the rotating shaft 33;

[0032] In addition, when the slide plate 34 moves, the slide plate 34 drives the measuring rod 36 to move, and the measuring rod 36 drives the roller b311 to move, so that the roller b311 contacts the outside of the tubular refractory material, thereby cooperating with the roller a310. The thickness of the tubular refractory material can be intuitively observed through the scale on the slide plate 34, and the thickness of the tubular refractory material can be continuously measured during the process of the tubular refractory material moving and grinding in the direction of the motor c32, thereby improving the production quality of the tubular refractory material.

[0033] The frame 1 is provided with an anti-splash mechanism 4 for cooperating with the rotating disk 35 to prevent waste chips from splashing. The anti-splash mechanism 4 includes a fixed disk 41 standing on the frame 1, a sleeve 42 passing through the fixed disk 41, a sleeve rod 43 inserted into the interior of the sleeve 42, a cover 45 for closing one end of the tubular refractory material is installed at one end of the sleeve rod 43, and a collecting barrel 44 for collecting waste chips is connected to one side of the cover 45. When finely grinding the tubular refractory material, the rotating disk 35 extends into the interior of the tubular refractory material to close the other end of the tubular refractory material, and cooperates with the cover 45 to close both ends of the tubular refractory material, and a rubber ring b is provided on the outside of the cover 45;

[0034] See also Figures 3 to 8 As shown, after adjusting the position of the grinding assembly 37, start the motor c32 and the motor b, and the motor b drives the grinding disc to work. Since the tubular refractory material is fixedly clamped on the fixture 24 at this time, the cover 45 and one end of the tubular refractory material are closed, and then the slide rail a21 is moved on the slide rail b23, and the slide rail a21 drives the support 22 to move. The support 22 drives the tubular refractory material to move through the fixture 24, so that the tubular refractory material is close to the turntable 35. When the tubular refractory material moves to a certain position, the grinding assembly 37 extends into the interior of the tubular refractory material. At this time, the grinding assembly 37 follows the turntable 35 to rotate and grinds the inner wall of the tubular refractory material. The rotation speed of the motor c32 and the movement speed of the slide rail a21 are controlled, and the grinding work of the grinding assembly 37 can be freely adjusted.

[0035] During the grinding process, the roller b311 moves on the outside of the tubular refractory material and is always in contact with it, and cooperates with the roller a310 to continuously detect the thickness of the tubular refractory material at various locations, further improving the production quality of the tubular refractory material;

[0036] In addition, after the turntable 35 enters the interior of the tubular refractory material, the other end of the tubular refractory material is closed. At this time, the sealing cover 45 is used to close one end of the tubular refractory material, thereby closing both ends of the tubular refractory material, thereby preventing the waste chips from grinding the inner wall of the tubular refractory material from splashing to the outside and affecting the working environment of the staff.

[0037] In addition, when the tubular refractory material moves following the support 22, the tubular refractory material drives the sleeve rod 43 to move, and the sleeve rod 43 penetrates into the interior of the sleeve 42. The scale on the outside of the sleeve rod 43 can guide the movement of the tubular refractory material, and at the same time, the grinding length of the tubular refractory material can be detected, thereby further improving the grinding accuracy of the tubular refractory material and improving the production quality of the tubular refractory material.

[0038] Working principle: The tubular refractory material is clamped and fixed on the support 22 by the clamp 24, and then the motor a is installed on the slide rail a21 and the slide rail b23, and the output ends of the two motors a are installed with screws, and the two screws are slid with bearing seats, the screws and the bearing seats are connected by ball nut pairs, and the two bearing seats are respectively connected to the slide rail a21 and the support 22, so the support 22 carrying the tubular refractory material can be controlled by the two motors a to adjust the position on the slide rail a21;

[0039] Before grinding, slide the adjusting disk 39 on the turntable 35, and the adjusting disk 39 drives the grinding assembly 37 to move. According to the size of the tubular refractory material, the position of the grinding assembly 37 can be flexibly adjusted so that the grinding disk on the grinding assembly 37 can grind the inner wall of the tubular refractory material. After the adjustment is completed, the adjusting disk 39 and the limiting groove 38 can be fixed by bolts b to make it stable. After the motor C32 is started, the output end of the motor C32 drives the rotating shaft 33 to rotate, and the rotating shaft 33 drives the turntable 35 to rotate. The turntable 35 rotates through the adjusting disk 39, and the adjusting disk 39 drives the grinding assembly 37 to rotate, so that the inner wall of the tubular refractory material can be ground during the rotation of the grinding assembly 37.

[0040] When adjusting the adjusting disk 39, the roller a310 on one side of the adjusting disk 39 is in contact with the inner wall of the tubular refractory material, and the adjusting disk 39 drives the connecting rod 312 to move, and the connecting rod 312 drives the slide plate 34 to move, and the slide plate 34 slides on the transition ring 313. The adjustment range of the adjusting disk 39 can be visually checked through the scale on the slide plate 34, thereby helping the group to adjust the position of the grinding assembly 37; at the same time, after the adjustment of the slide plate 34 is completed, the slide plate 34 is provided with a bolt a connected with the transition ring 313, which can assist in fixing the slide plate 34 with the transition ring 313, so that the slide plate 34 can rotate with the rotating shaft 33 during the rotation of the rotating shaft 33;

[0041] In addition, when the slide plate 34 moves, the slide plate 34 drives the measuring rod 36 to move, and the measuring rod 36 drives the roller b311 to move, so that the roller b311 contacts the outer side of the tubular refractory material;

[0042] After adjusting the position of the grinding assembly 37, start the motor c32 and the motor b, and the motor b drives the grinding disc to work. Since the tubular refractory material is fixedly clamped on the clamp 24 at this time, the cover 45 is then closed with one end of the tubular refractory material, and then the slide rail a21 is moved on the slide rail b23. The slide rail a21 drives the support 22 to move. The support 22 drives the tubular refractory material to move through the clamp 24, so that the tubular refractory material approaches the turntable 35. When the tubular refractory material moves to a certain position, the grinding assembly 37 extends into the interior of the tubular refractory material. At this time, the grinding assembly 37 follows the turntable 35 to rotate and grind the inner wall of the tubular refractory material. The rotation speed of the motor c32 and the movement speed of the slide rail a21 are controlled, and the grinding work of the grinding assembly 37 can be freely adjusted.

[0043] In addition, after the turntable 35 enters the interior of the tubular refractory material, the other end of the tubular refractory material is closed. At this time, the sealing cover 45 is used to close one end of the tubular refractory material, thereby closing both ends of the tubular refractory material, thereby preventing the waste chips from grinding the inner wall of the tubular refractory material from splashing to the outside and affecting the working environment of the staff.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
