Description

Technical Field

[0001] The utility model relates to the technical field of molybdenum disilicide production, in particular to a block molybdenum disilicide crushing device. Background Art

[0002] Molybdenum disilicide is a silicon compound of metallic molybdenum, also known as molybdenum silicide. It is conductive and can form a silicon dioxide protective film on its surface under high temperature in an oxidizing atmosphere to prevent further oxidation. It has a gray metallic appearance. Molybdenum disilicide is used in electric heating elements, high-temperature anti-oxidation coating materials, structural materials, reinforcers for composite materials, wear-resistant materials, connecting materials for structural ceramics, etc. Molybdenum disilicide needs to be crushed during processing.

[0003] When traditional crushing equipment is in use, during normal operation, the outer wall of the material and the crushing roller will collide with each other, which will produce large vibrations. Traditional equipment does not have the effect of filtering vibrations. The vibrations are transmitted to the ground, which will produce large noise on the one hand, and will also be transmitted back to the equipment body on the other hand. If the equipment works in an environment with long-term large vibrations, the overall service life of the equipment will be reduced. Utility Model Content

[0021] By installing a crushing bin 9 in the inner cavity of the support frame 1 and a crushing roller 10 in the inner cavity of the crushing bin 9, when the block molybdenum disilicide needs to be crushed, it is only necessary to put the material into the inner cavity of the crushing bin 9, and then the crushing rollers 10 on both sides can squeeze and roll down to achieve the crushing of the block material.

[0022] In a preferred embodiment, the outer wall diameter of the lifting cylinder 3 matches the inner wall diameter of the fixed cylinder 4 , and the height of the outer wall of the inner cylinder 6 is greater than the height of the outer wall of the fixed cylinder 4 .

[0023] By arranging the lifting cylinder 3 and the fixed cylinder 4 at the bottom of the support frame 1 and the top of the support rod 2, the lifting cylinder 3 and the fixed cylinder 4 can achieve a shock-absorbing effect on the entire support frame 1, so that the equipment can have more stable working conditions during use, thereby better crushing.

[0024] In a preferred embodiment, the opening position of the air hole 5 corresponds to the installation position of the eardrum 8, and the inner cavity of the inner tube 6 is fixedly equipped with a closed partition.

[0025] Through the closed partition installed in the inner cavity of the inner cylinder 6, when the support frame 1 is vibrated and transmitted to the top of the lifting cylinder 3, the lifting cylinder 3 will move downward along the inner wall of the fixed cylinder 4, thereby squeezing the gas in the inner cavity of the lifting cylinder 3 downward, so that the gas passes through the air vent 5 into the inner cavity of the inner cylinder 6, and exerts a certain squeezing effect on the eardrum 8.

[0026] In a preferred embodiment, there are four lifting cylinders 3 , and the four lifting cylinders 3 are respectively installed at the bottom of the support frame 1 .

[0027] By installing a lifting cylinder 3 and a fixed cylinder 4 at the bottom of the four supporting legs of the support frame 1, the lifting cylinder 3 and the fixed cylinder 4 as well as the inner cylinder 6 and the eardrum 8 can realize the shock absorption of the whole equipment, so that the vibration generated by the equipment during the crushing process can be effectively filtered, thereby achieving a better and more stable crushing effect.

[0028] In a preferred embodiment, the outer wall of the driving assembly 12 meshes with the outer wall of the driven gear 11, the eardrum 8 is made of natural rubber, and the thickness of the eardrum 8 is 5CM of the air hole.

[0029] By means of a driving assembly 12 arranged on the outer wall of the crushing bin 9, the crushing roller 10 and the driven gear 11 are driven under the action of the driving assembly 12, and the outer walls of the crushing rollers 10 on both sides are installed with driven gears 11 and driving assemblies 12, so that the crushing rollers 10 on both sides can be controlled separately, so as to realize relative rotation of the driven gears 11 on both sides, and then the crushing effect can be achieved when the crushing rollers 10 on both sides rotate relative to each other.

[0030] In a preferred embodiment, a limiting ring is fixedly mounted on the outer wall of the piston rod 7 close to the fixed cylinder 4 , and the outer wall diameter of the limiting ring is larger than the outer wall diameter of the piston rod 7 .

[0031] By means of the limiting ring arranged on the outer wall of the piston rod 7, when the piston rod 7 moves along with the movement of the lifting cylinder 3, the outer wall of the piston rod 7 will enter the inner cavity of the fixed cylinder 4. At this time, the outer wall of the eardrum 8 will fit against the outer wall of the inner cylinder 6 under the action of air pressure, thereby preventing the inner cylinder 6 from continuing to move downward.

[0032] Working principle: When the above-mentioned equipment is in use, the molybdenum disilicide to be crushed is put into the inner cavity of the crushing bin 9, and then the driven gear 11 is driven to rotate under the action of the driving component 12, so that the crushing roller 10 also rotates synchronously, and the molybdenum disilicide is crushed in the process of synchronous counter-rotation of the crushing rollers 10 on both sides. In the process of crushing, the equipment will generate a certain vibration. When the vibration is transmitted to the top of the lifting cylinder 3, it will push the lifting cylinder 3 to move downward. At this time, the outer wall of the piston rod 7 will enter the inner cavity of the fixed cylinder 4, and under the action of the inner wall of the lifting cylinder 3 It will push the gas in the inner cavity of the lifting cylinder 3 into the inner cavity of the inner cylinder 6. At this time, the gas is in the inner cavity between the closing plate and the top of the inner cylinder 6, thereby squeezing the tympanic membrane 8, which in turn causes the tympanic membrane 8 to deform and then fit onto the outer wall of the piston rod 7, thereby blocking the piston rod 7 from continuing to move downward, thereby stopping the lifting cylinder 3 from moving downward. At this time, the air pressure in the inner cavity of the inner cylinder 6 increases and will enter the inner cavity of the lifting cylinder 3 from the air vent 5, thereby pushing the lifting cylinder 3 upward, thereby achieving a shock-absorbing effect during the up and down reciprocating motion of the lifting cylinder 3, making the working conditions of the equipment more stable.

[0033] 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.
