Description

Technical Field

[0001] The invention relates to the technical field of alloy production devices, in particular to a crushing device for large-particle alloy smelting. Background Art

[0002] In the metallurgical industry, the demand for large-particle alloys is increasing, especially in high-tech fields such as aerospace, automobile manufacturing and electronic equipment. Large-particle alloys have excellent physical and chemical properties, but in the smelting process, how to effectively crush raw materials to achieve the appropriate particle size and uniformity has become an important factor restricting the efficiency and quality of alloy production; compared with traditional crushers, multi-tooth roller crushers have higher crushing efficiency; their unique working principle and tooth shape design can more effectively crush materials into the required particle size.

[0003] However, when the existing multi-tooth roller crusher is being fed, the large particles of the material are in direct contact with the high-speed rotating tooth rollers, causing particles to splash everywhere, which may not only pose a safety threat to the operator, especially when not wearing proper protective equipment, it is easy to cause accidental injuries such as eye injuries and skin scratches; and the high-speed rotating tooth rollers directly contacting the material may cause additional wear on the tooth roller surface, accelerate equipment wear, increase maintenance costs and replacement frequency. Although the existing technology also takes some preventive and improvement measures, such as installing protective covers or partitions, the added protective devices will increase the difficulty of feeding; therefore, it is necessary to set up a crushing device that can meet the conditions of sealed feeding and maintain normal feeding speed.

[0006] Preferably, the main driving assembly provides the driving force for the guide plate and the rotating assembly to move up and down at the same time; The guide plate realizes power conversion of the main driving component through the linkage component, and the upward and downward turning range of the guide plate is not less than 20°.

[0007] Preferably, the rotating assembly realizes power conversion of the main driving assembly through the driven assembly; The driven component includes: a movable hinge seat to drive the rotating component to move horizontally left and right, thereby acting alternately on the first rough grinding component and the second rough grinding component.

[0008] Preferably, the first rough grinding assembly is mirror-symmetrical to the second rough grinding assembly, the first rough grinding assembly comprises a first active gear roller and a first driven gear roller that perform reverse rotational motion, and a first active roller shaft connected to the rotating assembly is provided in the middle of the first active gear roller; A first driven roller shaft linked to the first active roller shaft is arranged in the middle of the first driven gear roller.

[0009] Preferably, the second rough grinding assembly comprises a second active gear roller and a second driven gear roller that perform reverse rotational motion, and a second active roller shaft connected to the rotating assembly is provided in the middle of the second active gear roller; A second driven roller shaft linked to the second active roller shaft is provided in the middle of the second driven gear roller.

[0010] Preferably, the ends of the first driven roller and the second driven roller are provided with a first self-locking component and a second self-locking component respectively, and both the first self-locking component and the second self-locking component realize power conversion of the main driving component through a connecting piece, and adaptively perform opening or closing actions.

[0011] Preferably, the first self-locking assembly comprises: two groups of mirror-symmetrical first pressing blocks; the first pressing blocks are provided with first driving grooves adapted to the connecting pieces; The second self-locking assembly comprises: two sets of mirror-symmetrical second pressing blocks; the second pressing blocks are provided with second driving grooves adapted to the connecting pieces; The first pressing block and the second pressing block both move linearly toward each other.

[0012] Preferably, the first driving groove consists of an upper radial groove and a lower oblique groove, and the second driving groove consists of an upper oblique groove and a lower radial groove, and the inclination angles of the lower oblique groove and the upper oblique groove are opposite, so that the first pressing block and the second pressing block maintain opposite movement states.

[0013] Preferably, the movable articulated seat moves horizontally in the machine body and is provided with an oblique groove, and the main driving assembly is provided with a toggle rod for providing a vertical driving force to the oblique groove.

[0014] Preferably, the first active roller shaft and the first driven roller shaft, as well as the second active roller shaft and the second driven roller shaft are connected via a transmission assembly; The transmission assembly includes two sets of intermeshing linkage wheels of the same size.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention provides a guide plate that performs up-and-down flipping motion, so as to divert the falling materials and alternately guide them between the first coarse grinding assembly and the second coarse grinding assembly, and the coarse grinding assembly at the material discharge end of the guide plate is in a stationary state; while the upper end of the other group of coarse grinding assemblies in motion is blocked by the guide plate, thereby achieving the effect of static feeding and crushing in a sealed state; compared with the prior art, the present device can prevent material splashing and leakage while ensuring the normal feeding speed, thereby protecting the safety of the operator.

[0016] 2. The present invention has strong mechanical linkage. By setting a rotating shaft, a spur gear, a vertical rack and a connecting plate for use, the radial driving force of the electric push rod can be converted into the up and down turning movement of the guide plate; by setting a toggle rod, an oblique groove and a movable hinge seat for use, the vertical driving force of the connecting plate can be converted into the horizontal left and right movement of the driving wheel, and the displacement of the left and right movement is the same, so that the main gear can adaptively mesh with the first driven wheel and the second driven wheel alternately according to the inclination direction of the guide plate.

[0017] 3. Since the first coarse grinding assembly and the second coarse grinding assembly are always in a static and moving state, the material can be simultaneously crushed in the sealed mode and in the static feeding mode. In this process, the guide plate firstly has a certain degree of buffering effect on the material, and the coarse grinding assembly receives the material statically, so that the material can be fed into the crushing chamber more evenly and stably, avoiding uneven material flow caused by dynamic operation, thereby improving the crushing efficiency and the consistency of the product particle size.

[0018] 4. By arranging the cylindrical pin, the vertical push bar and the driven beam to cooperate with the first driving groove and the second driving groove in sequence, the linear up and down movement of the connecting plate can be converted into the horizontal movement of the two groups of first pressing blocks and the two groups of second pressing blocks, and the movement directions of the first pressing blocks and the second pressing blocks are opposite. When the guide plate tilts toward the first driven gear roller, the first pressing block immediately locks the first driven roller shaft, so that the first driven gear roller is stable in a static state. At this time, the second pressing block immediately releases the first driven roller shaft, so that the first driven gear roller can move normally. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figures 1 to 10 The present invention provides a technical solution: a crushing device for large-particle alloy smelting, comprising a machine body 1, a multi-tooth roller is arranged in the machine body 1, and the large-particle alloy can be crushed multiple times. The machine body 1 is provided with a feed port 2, a first processing chamber 3, a second processing chamber 4 and a collection chamber 5 from top to bottom. The first processing chamber 3 is set as a round-shaped chamber. The material is introduced from the feed port 2 and is diverted through the first processing chamber 3, and then aggregated in the second processing chamber 4 and finally falls into the collection chamber 5 for collection; A guide plate 6, a first coarse grinding assembly and a second coarse grinding assembly are arranged in the first processing chamber 3; the guide plate 6 is arranged directly below the feed port 2, and the guide plate 6 is driven by the main driving assembly to perform an up-and-down flipping motion, so as to alternately guide the materials into the first coarse grinding assembly and the second coarse grinding assembly; The first coarse grinding assembly and the second coarse grinding assembly are driven by the same set of rotating assemblies and realize alternating operation, so as to achieve the effect of synchronously performing the two states of static material feeding and sealed crushing; The second processing chamber 4 is provided with a fine grinding assembly, which includes two sets of auxiliary tooth rollers 27 that move synchronously in opposite directions. The spacing between the two sets of auxiliary tooth rollers 27 is much smaller than the spacing between two adjacent sets of coarse grinding tooth rollers, so that the material processed by the coarse grinding assembly can be finely crushed again.

[0032] Furthermore, the present invention provides a guide plate 6 that performs an upside-down flipping movement to divert the falling materials and alternately guide them between the first coarse grinding assembly and the second coarse grinding assembly, and the coarse grinding assembly at the material discharge end of the guide plate 6 is in a stationary state; while the upper end of the other group of coarse grinding assemblies in motion is blocked by the guide plate 6, thereby achieving static feeding and crushing in a sealed state; compared with the prior art, the present device can prevent material splashing and leakage while ensuring the normal feeding speed, thereby protecting the safety of the operator.

[0033] like Figure 5 , Fig. 9 as well as Fig.10As shown, the main drive assembly provides the driving force for the guide plate 6 and the rotating assembly to move up and down at the same time; the guide plate 6 realizes the power conversion of the main drive assembly through the linkage assembly, and the guide plate 6 flips up and down by not less than 20°; the linkage assembly includes a rotating shaft 7, a spur gear 8 and a vertical rack 9, the rotating shaft 7 is fixedly inserted in the middle of the guide plate 6, and the end of the rotating shaft 7 is coaxially fixedly connected to the spur gear 8; the main drive assembly includes a connecting plate 10 and an electric push cylinder 11, the connecting plate 10 is limitedly slidably installed in the body 1, the piston rod of the electric push cylinder 11 extends outward and is fixedly connected to the upper end surface of the connecting plate 10, one end of the vertical rack 9 is fixedly connected to the connecting plate 10, and the other end of the vertical rack 9 is meshedly connected to the spur gear 8.

[0034] Furthermore, the present invention has strong mechanical linkage. By setting the rotating shaft 7, the spur gear 8, the vertical rack 9 and the connecting plate 10 for use together, the radial driving force of the electric push rod can be converted into the up and down turning movement of the guide plate 6.

[0035] like Fig. 9 as well as Fig.10 As shown, the rotating assembly realizes the power conversion of the main driving assembly through the driven assembly; the driven assembly includes: a mobile hinge seat 14 to drive the rotating assembly to move horizontally left and right, so as to act alternately on the first rough grinding assembly and the second rough grinding assembly; the mobile hinge seat 14 moves horizontally in the machine body 1 and is provided with an oblique groove 13, and the main driving assembly is provided with a toggle rod 12 that provides vertical driving force to the oblique groove 13. The rotating assembly includes a driving wheel 15, which is limitedly rotated and installed on the mobile hinge seat 14 and driven to rotate by a rotating motor; the first active roller shaft 17 is coaxially fixedly connected to the first driven wheel 16 at one end close to the active wheel 15, and the second active roller shaft 20 is coaxially fixedly connected to the second driven wheel 21 at one end close to the active wheel 15.

[0036] Furthermore, by setting up a toggle rod 12, an oblique groove 13 and a movable hinge seat 14 for use together, the vertical driving force of the connecting plate 10 can be converted into horizontal left and right movement of the driving wheel 15, and the left and right movement displacements are the same, so that the main gear can adaptively mesh with the first driven wheel 16 and the second driven wheel 21 alternately according to the inclination direction of the guide plate 6.

[0037] like Figures 4 to 7As shown, the first rough grinding assembly is mirror-symmetrical with the second rough grinding assembly. The first rough grinding assembly includes a first active gear roller 18 and a first driven gear roller 24 that perform reverse rotation. The first active gear roller 18 is provided with a first active roller shaft 17 connected to the rotating assembly in the middle; the first driven gear roller 24 is provided with a first driven roller shaft 23 that is linked to the first active roller shaft 17 in the middle. The second rough grinding assembly includes a second active gear roller 19 and a second driven gear roller 26 that perform reverse rotation. The second active gear roller 19 is provided with a second active roller shaft 20 connected to the rotating assembly in the middle; the second driven gear roller 26 is provided with a second driven roller shaft 25 that is linked to the second active roller shaft 20 in the middle. The first active roller shaft 17 and the first driven roller shaft 23, as well as the second active roller shaft 20 and the second driven roller shaft 25, are connected through a transmission assembly; the transmission assembly includes two sets of interlocking wheels 22 of the same size and meshing with each other.

[0038] Furthermore, since the first coarse grinding assembly and the second coarse grinding assembly are always in a static and moving state and switch back and forth, the material can be simultaneously crushed in the sealed crushing mode and through the static feeding mode. In this process, the material can be fed into the crushing chamber more evenly and stably, avoiding the uneven material flow caused by dynamic operation, thereby improving the crushing efficiency and the particle size consistency of the product.

[0039] like Figures 7 and 8 As shown, the ends of the first driven roller shaft 23 and the second driven roller shaft 25 are provided with the first self-locking component and the second self-locking component in sequence, and the first self-locking component and the second self-locking component both realize the power conversion of the main driving component through the connecting piece, and adaptively perform the opening or closing action; the connecting piece includes a cylindrical pin 30, a vertical push bar 31 and a driven beam 32, one end of the vertical push bar 31 is fixedly connected to the driven beam 32, and the other end of the vertical push bar 31 is fixedly connected to the cylindrical pin 30; the first self-locking component includes: two groups of mirror-symmetrical first pressing blocks 28; the first pressing blocks 28 are provided with a first driving groove 29 adapted to the cylindrical pin 30; the second self-locking component includes: two groups of mirror-symmetrical second pressing blocks 33; the second pressing blocks 33 are provided with a second driving groove 34 adapted to the cylindrical pin 30; the first pressing blocks 28 and the second pressing blocks 33 both move linearly towards each other. The first driving groove 29 is composed of an upper radial groove and a lower inclined groove, and the second driving groove 34 is composed of an upper inclined groove and a lower radial groove, and the inclination angle of the lower inclined groove is opposite to that of the upper inclined groove, so that the first pressing block 28 and the second pressing block 33 maintain opposite movement states.

[0040] Furthermore, by arranging a cylindrical pin 30, a vertical push bar 31 and a driven beam 32 for use in conjunction with the first drive groove 29 and the second drive groove 34 in sequence, the linear up and down movement of the connecting plate 10 can be converted into horizontal opposite movements of two groups of first pressure blocks 28 and two groups of second pressure blocks 33, and the movement directions of the first pressure blocks 28 and the second pressure blocks 33 are opposite. When the guide plate 6 tilts toward the first driven gear roller 24, the first pressure block 28 immediately locks the first driven roller shaft 23, so that the first driven gear roller 24 is stabilized in a stationary state. At this time, the second pressure block 33 immediately releases the first driven roller shaft 23, so that the first driven gear roller 24 can move normally.

[0041] When the present invention is in use: the crushed alloy material is introduced into the first processing chamber 3 from the feed port 2, and under the guiding action of the guide plate 6, it alternately enters between the first coarse grinding assembly and the second coarse grinding assembly. During this process, the guide plate 6 performs an intermittent 20° up and down flipping movement. When the guide plate 6 tilts toward the first coarse grinding assembly, the feed port 2 of the second coarse grinding assembly is blocked; at this time, the toggle rod 12 on the connecting plate 10 is located at the lower end of the oblique groove 13, so that the movable hinge seat 14 is close to the second active roller shaft 20, the active wheel 15 is disengaged from the first driven wheel 16 and is engaged with the second driven wheel 21. At this time, the first pressing block 28 quickly locks the first driven roller shaft 23, so that the first active gear roller 18 and the first driven gear roller 24 remain stationary to receive the falling material, and the second pressing block 33 quickly releases the second driven roller shaft 25, so that the second active gear roller 19 and the second driven gear roller 26 rotate synchronously in the opposite direction The guide plate 6 moves to crush the materials piled thereon. Similarly, when the guide plate 6 tilts toward the second coarse grinding assembly, the feed port 2 of the first coarse grinding assembly is blocked. At this time, the toggle rod 12 on the connecting plate 10 enters the upper end of the oblique groove 13, so that the movable hinge seat 14 is close to the first active roller shaft 17, and the active wheel 15 is disconnected from the second driven wheel 21 and is engaged with the first driven wheel 16. At this time, the second pressing block 33 quickly locks the second driven roller shaft 25, so that the second active gear roller 19 and the second driven gear roller 26 remain stationary to receive the falling materials, and the first pressing block 28 quickly releases the first driven roller shaft 23, so that the first active gear roller 18 and the first driven gear roller 24 perform reverse synchronous rotation, thereby crushing the materials piled thereon, and the crushed materials enter the second processing chamber 4 and are crushed again by the auxiliary gear roller 27, so as to achieve a finer crushing particle size requirement.

[0042] 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.
