Description

[0002] The tungsten-molybdenum alloy assembly is various types of parts or devices made of tungsten-molybdenum alloy, such as a tungsten-molybdenum alloy crucible. The tungsten-molybdenum alloy crucible is used to hold high-temperature liquid metal or chemical substances. After use, the inner wall of the crucible will have residues of the melted material.

[0003] Currently, the residues of the melted material remaining on the inner wall of the crucible are mainly cleaned by wiping and brushing. However, the traditional wiping and brushing cannot timely remove the impurities outside the crucible, so the impurities are easily pushed by the brush to rub against the inner wall of the crucible, causing scratches on the inner wall of the crucible and reducing the service life of the crucible. In addition, for some stubborn impurities that are solidified on the inner wall of the crucible, it is usually necessary to lengthen the brushing time and increase the brushing force.

[0034] Referring to Figure 1 and Figure 2 , a tungsten-molybdenum alloy component cleaning device comprises a device frame 1, a conveying mechanism 2 arranged on the device frame 1 for conveying a crucible, a lifting frame 3 arranged on the front of the device frame 1 through a guide column to slide up and down, a supporting plate 4 fixedly installed on the upper part of the lifting frame 3, a rotating cylinder 5 rotatably arranged in the middle of the supporting plate 4, and the cleaning device further comprises a scrubbing mechanism 6 for scrubbing the inner wall of the crucible, and a decontamination mechanism 7 arranged on the rotating cylinder 5 for removing stubborn impurities.

[0035] When the inner wall of the tungsten-molybdenum alloy crucible needs to be cleaned, first, the tungsten-molybdenum alloy crucible is conveyed in an inverted manner with the opening facing downward to the upper part of the rotating cylinder 5 coaxially with the rotating cylinder 5 through the conveying mechanism 2, then the position of the crucible is clamped and fixed by the conveying mechanism 2, then the lifting frame 3 is moved upward, so that the lifting frame 3 drives the rotating cylinder 5 to move to the inside of the crucible through the supporting plate 4, then the rotating cylinder 5 is rotated, and the inner wall of the crucible is scrubbed and cleaned by the scrubbing mechanism 6, while the stubborn impurities on the inner wall of the crucible are removed by the decontamination mechanism 7.

[0036] Continuing to refer to Figure 1 and Figure 2 , the conveying mechanism 2 comprises two groups of conveying rollers 21 arranged symmetrically left and right on the inner side of the upper part of the device frame 1, each group is composed of a plurality of conveying rollers 21 rotatably arranged on the device frame 1 at equal intervals in the front-rear direction, and two drive motors 22 are fixedly installed on the device frame 1 to drive a corresponding group of conveying rollers 21 in position respectively.

[0037] Continuing to refer to Figure 1 and Figure 2 , the conveying mechanism 2 further comprises two first hydraulic rods 23 fixedly installed on the outer side of the upper part of the device frame 1 and arranged symmetrically left and right, and the end of the telescopic section of the first hydraulic rod 23 is fixedly installed with a clamping plate 24 for pushing the crucible and arranging the crucible coaxially with the rotating cylinder 5.

[0038] When the crucible needs to be cleaned, first, the crucible is inverted and placed on the conveying rollers 21 at the rear of the device frame 1, then the drive motors 22 on both sides are started simultaneously to drive all the conveying rollers 21 to start rotating in the same direction, so that the conveying rollers 21 convey the inverted crucible forward by means of relay transmission.

[0039] When the crucible is moved between the two clamping plates 24, the driving motor 22 is stopped, and the extension sections of the two hydraulic rods 23 are extended synchronously, so that the two clamping plates 24 are moved towards each other to clamp and fix the crucible, thereby pushing the crucible to the upper side of the rotating cylinder 5 coaxially with the rotating cylinder 5.

[0040] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , a strip-shaped brush 52 is arranged on the upper end of the rotating cylinder 5 along the radial direction thereof, and a threaded rod 53 is arranged on the upper end of the rotating cylinder 5 and rotates along the radial direction thereof, the threaded rod 53 is threadedly connected with the strip-shaped brush 52, and a second hydraulic rod 42 is fixedly installed on the device frame 1, and the extension section of the second hydraulic rod 42 is fixedly connected with the supporting plate 4.

[0041] When the position of the crucible is fixed above the rotating cylinder 5, the operator manually rotates the threaded rod 53, so that the threaded rod 53 drives the strip-shaped brush 52 to move along the radial direction of the rotating cylinder 5 until the strip-shaped brush 52 is opposite to the inside of the rotating cylinder 5, so that the rotating cylinder 5 drives the strip-shaped brush 52 to enter the crucible in the subsequent process, and the strip-shaped brush 52 can completely cover the inner bottom wall of the crucible, and then the extension section of the second hydraulic rod 42 is extended to drive the rotating cylinder 5 to move upwards to the inside of the crucible through the supporting plate 4 until the rotating cylinder 5 drives the strip-shaped brush 52 to abut against the inner bottom wall of the crucible.

[0042] Referring to Figure 2 , Figure 3 , Figure 4 and Figure 5 , the brushing mechanism 6 comprises a plurality of moving plates 61 slidably arranged on the rotating cylinder 5, and a bristle block 62 is fixedly installed on the end of each moving plate 61 away from the axis of the rotating cylinder 5, the bristle block 62 is driven by a driving assembly 63 commonly arranged on the lifting frame 3 and the rotating cylinder 5 to abut against the inner wall of the crucible for brushing, and a plurality of conical ring members 65 for guiding impurities are fixedly installed on the outer side of the rotating cylinder 5 along the vertical direction at equal intervals.

[0043] Referring to Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 9 , the inner side of each conical ring member 65 is provided with a receiving frame 651 at equal intervals along the circumferential direction of the rotating cylinder 5, the receiving frame 651 is connected with the conical ring member 65 in a detachable manner, a guide plate 652 is fixedly installed on the upper part of the side of the receiving frame 651 close to the axis of the rotating cylinder 5, and the side of the cross section of the guide plate 652 away from the axis of the rotating cylinder 5 is inclined to the direction away from the axis of the rotating cylinder 5.

[0044] Referring to Figure 2 ,Figure 3 、 Figure 4 and Figure 5 , several moving plates 61 are equidistantly distributed in the vertical direction into groups, each group is composed of moving plates 61 equidistantly distributed along the circumference of the rotating cylinder 5, the end of the moving plate 61 away from the axis of the rotating cylinder 5 is inclined upward, the moving plate 61 is slidingly connected to the rotating cylinder 5 along the inclined direction, and several moving plates 61 are alternately distributed with several conical ring members 65.

[0045] Continue to refer to Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , the drive assembly 63 includes a driving rod 631 slidingly arranged inside the rotating cylinder 5 at a coaxial position, a hinge plate 632 corresponding to the moving plate 61 is hinged on the driving rod 631, the end of the hinge plate 632 away from the driving rod 631 is hinged to the moving plate 61 at the corresponding position, the lower part of the lifting frame 3 is fixedly installed with a telescopic section, the driving rod 631 is rotationally connected with an electric push rod 633, and the electric push rod 633 is arranged in front of and behind the second hydraulic rod 42.

[0046] When the strip-shaped brush 52 abuts against the bottom wall of the crucible, the telescopic section of the electric push rod 633 drives the driving rod 631 to move upward, the driving rod 631 pushes the moving plate 61 away from the axis of the rotating cylinder 5 through the hinge plate 632, so that the moving plate 61 drives the brush block 62 thereon to abut against the inner side wall of the crucible, and the uppermost brush block 62 can abut against the arc-shaped wall at the junction of the inner bottom wall and the inner side wall of the crucible.

[0047] Continue to refer to Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , the supporting plate 4 is fixedly installed with an execution motor 41 at the lower right side, the output shaft of the execution motor 41 is connected with the rotating cylinder 5 through a bevel gear transmission and drives the rotating cylinder 5 to rotate.

[0048] When the brush block 62 abuts against the inner side wall of the crucible, the execution motor 41 is started to drive the rotating cylinder 5 to start rotating, the rotating cylinder 5 drives the brush block 62 and the strip-shaped brush 52 to rotate synchronously through the moving plate 61, so that the brush block 62 brushes the inner side wall and the arc-shaped wall of the crucible, and the strip-shaped brush 52 brushes the inner bottom wall of the crucible, after a period of continuous brushing, the telescopic section of the second hydraulic rod 42 is intermittently retracted to drive the rotating cylinder 5 to move downward, so that the rotating cylinder 5 drives the brush block 62 to comprehensively brush the inner side wall of the crucible. It should be noted that Figures 2-5 the brush blocks 62 are all in the position state of abutting against the inner wall of the crucible.

[0049] The impurities brushed off by the bristle block 62 fall under the action of gravity into the receiving frame 651 on the inner side of the corresponding conical ring 65, and are guided to the inside of the receiving frame 651 through the inclined surface structure on the guide plate 652, preventing the impurities from accumulating on the side of the receiving frame 651 close to the rotating cylinder 5, thereby preventing the impurities from falling onto the bristle block 62 and preventing the bristle block 62 from pushing the impurities to rub against the inner wall of the crucible and scratch the inner wall of the crucible. After the crucible is cleaned, the receiving frame 651 can be removed for collection and treatment of the impurities. If there are impurities on the inner side of the conical ring 65 that do not fall into the receiving frame 651, the impurities can be manually swept into the receiving frame 651 with a cleaning tool, and then the receiving frame 651 is removed.

[0050] Referring to Figure 2 , Figure 3 and Figure 4 , the brushing mechanism 6 further comprises a carding assembly 64 for carding the bristle block 62 under the drive of the driving assembly 63, the carding assembly 64 comprising a plurality of moving rings 641 arranged equidistantly in the vertical direction outside the rotating cylinder 5 and slidingly connected thereto, the moving rings 641 being located below a corresponding set of moving plates 61, and a plurality of carding teeth 642 being fixedly installed equidistantly in the circumferential direction of the moving rings 641 for carding the bristle block 62.

[0051] Referring to Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 8 , the carding assembly 64 further comprises a sliding plate 643 fixedly installed outside the plurality of moving rings 641, the lower end of the sliding plate 643 slidingly penetrating all the conical rings 65 to the lower side of the rotating cylinder 5, the lower part of the rotating cylinder 5 being hingedly connected to a linkage plate 644 through a support plate, a torsional spring being provided between the linkage plate 644 and the support plate of the rotating cylinder 5, the torsional spring not being shown in the figure, a first notch 645 being formed on the side of the linkage plate 644 away from the axis of the rotating cylinder 5, a second notch 646 being formed on the side of the linkage plate 644 close to the axis of the rotating cylinder 5, a pin shaft being hingedly connected to the lower part of the sliding plate 643 and slidingly fitted into the first notch 645, the lower part of the driving rod 631 slidingly penetrating the second notch 646, a boss 647 being fixedly installed outside the driving rod 631 and located above the linkage plate 644.

[0052] When the bristle block 62 continuously brushes the inside wall of the crucible at a certain height, the telescopic section of the electric push rod 633 is retracted, and the bristle block 62 moves towards the axis of the rotating cylinder 5, and the boss 647 on the driving rod 631 moves downwards synchronously. When the boss 647 contacts the linkage plate 644, the boss 647 pushes the linkage plate 644 to rotate, the No. 2 notch 646 on the linkage plate 644 moves downwards, and the No. 1 notch 645 moves upwards, so that the linkage plate 644 drives all the moving rings 641 to move upwards synchronously through the sliding plate 643. The moving rings 641 drive the combs 642 to insert into the bristles of the bristle block 62, and then the telescopic section of the electric push rod 633 is retracted, so that the combs 642 comb the bristle block 62, so that the combs 642 comb and remove the impurities inside and at the ends of the bristle block 62. The removed impurities fall on the conical ring 65, further preventing the impurities from scratching the inner wall of the crucible. Then the telescopic section of the electric push rod 633 is extended again, so that the boss 647 moves upwards, and the bristle block 62 continues to brush the crucible. The linkage plate 644 is rotated to the initial position by the rotary elastic force of the torsion spring and the gravity of the combs 642, the sliding plate 643 and the moving rings 641, and the combs 642 move downwards to the initial position synchronously.

[0053] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 , the impurity removing mechanism 7 includes a guide assembly 71 arranged on the rotating cylinder 5, and a plurality of sliding plates 72 connected to the guide assembly 71. A plurality of arc-shaped grooves 51 are formed in the cylinder wall of the rotating cylinder 5, and the sliding plates 72 slide in the corresponding arc-shaped grooves 51. An arc-shaped pry plate 73 is hinged to one end of the sliding plate 72 away from the axis of the rotating cylinder 5. By pushing the arc-shaped pry plate 73, the sliding plate 72 rotates along the circumference of the rotating cylinder 5 and moves towards the axis of the rotating cylinder 5 under the guidance of the guide assembly 71, so as to remove stubborn impurities.

[0054] Referring to Figure 5 , Figure 6 and Figure 7The guide assembly 71 comprises a fixed disc 711 fixedly installed at the lower portion of the inner side of the rotating cylinder 5, and a plurality of sets of guide grooves 712 are evenly opened on the inner top wall of the rotating cylinder 5 and the fixed disc 711 along the circumferential direction of the rotating cylinder 5. A plurality of sliding plates 72 correspond to the plurality of sets of guide grooves 712 one by one and also correspond to the plurality of sets of moving plates 61 one by one, each set is composed of two guide grooves 712 arranged inside and outside, and a moving rod 713 is slidably arranged on the two upper and lower corresponding guide grooves 712 on the fixed disc 711 and the rotating cylinder 5. A tension spring is arranged between the moving rod 713 on the inner side and the fixed disc 711. The two moving rods 713 connected with the same set of guide grooves 712 are slidably connected with the corresponding sliding plate 72 in the upper and lower directions, and the sliding plate 72 is located between the two adjacent moving plates 61 in the corresponding position.

[0055] Referring to Figure 5 , Figure 6 and Figure 7 , the guide grooves 712 are arc grooves, one end of which is close to the axis of the rotating cylinder 5, and the other end is away from the axis of the rotating cylinder 5. A plurality of arc grooves 51 are arranged at equal intervals in the upper and lower directions, and in the perspective view, the plurality of arc grooves 51 are arranged at equal intervals along the circumferential direction of the rotating cylinder 5.

[0056] In the initial state, under the action of the elastic force of the tension spring, the moving rod 713 abuts against one end of the corresponding guide groove 712. When the brush block 62 brushes the crucible, the rotating cylinder 5 synchronously drives the fixed disc 711 to rotate, so that the fixed disc 711 and the rotating cylinder 5 synchronously drive all the moving rods 713 to rotate, so that the moving rod 713 drives the sliding plate 72 to synchronously rotate, and the sliding plate 72 drives the arc-shaped pry plate 73 to rotate around the inner side wall of the crucible.

[0057] When there is stubborn impurity adhered to the inner side wall of the crucible, the rotating cylinder 5 drives the arc-shaped pry plate 73 to move to contact the stubborn impurity. The stubborn impurity will block the arc-shaped pry plate 73, so that the arc-shaped pry plate 73 drives the sliding plate 72 to stop synchronously rotating with the rotating cylinder 5, and then the sliding plate 72 rotates relative to the rotating cylinder 5 in the opposite direction of the rotating direction of the rotating cylinder 5. The sliding plate 72 drives the moving rod 713 to move along the track of the guide groove 712, and the moving rod 713 stretches the tension spring, thereby preventing the arc-shaped pry plate 73 from rigidly contacting the stubborn impurity, and avoiding that the arc-shaped pry plate 73 directly impacts the impurity with great force to scratch the inner side wall of the crucible. As the arc-shaped pry plate 73 gradually removes the stubborn impurity, the stretching degree of the tension spring gradually increases, so that the pushing force of the arc-shaped pry plate 73 on the stubborn impurity gradually increases, and finally the arc-shaped pry plate 73 completely removes the stubborn impurity.

[0058] Referring to Figure 3 , Figure 6 and Figure 7The removing mechanism 7 further comprises a prying assembly 74 for driving the arc-shaped prying plate 73 to pry the stubborn impurities, the prying assembly 74 comprises a top plate member 741 arranged on the sliding plate 72 at a side opposite to the rotating direction of the rotating cylinder 5, the top plate member 741 is slidingly arranged along the length direction of the sliding plate 72, the side of the top plate member 741 close to the axis of the rotating cylinder 5 slides on the arc-shaped groove 51 along the track of the arc-shaped groove 51, and the side of the top plate member 741 away from the axis of the rotating cylinder 5 is hingedly connected to the side of the arc-shaped prying plate 73 close to the axis of the rotating cylinder 5.

[0059] When the moving rod 713 moves along the track of the guide groove 712, under the guidance and limitation of the guide groove 712, the moving rod 713 drives the sliding plate 72 to move towards the axis of the rotating cylinder 5, the sliding plate 72 drives the arc-shaped prying plate 73 on the sliding plate 72 to move synchronously, the top plate member 741 is not driven to move with the sliding plate 72 due to the limitation of the arc-shaped groove 51, so that the top plate member 741 moves away from the axis of the rotating cylinder 5 relative to the sliding plate 72, and the side of the arc-shaped prying plate 73 away from the corresponding top plate member 741 is deflected towards the axis of the rotating cylinder 5 by the top plate member 741, so that the arc-shaped prying plate 73 prys the stubborn impurities while shoveling the stubborn impurities, thereby increasing the removal effect of the stubborn impurities.

[0060] Referring to Figures 1-9 The present application is used for cleaning the inner wall of a tungsten-molybdenum alloy crucible, and specifically comprises the following steps:

[0061] Firstly, the crucible is inverted and placed on the conveying rollers 21 at the rear of the device frame 1, then the driving motors 22 on both sides are started to drive all the conveying rollers 21 to convey the inverted crucible forward to the position above and coaxial with the rotating cylinder 5, and the crucible is clamped and fixed by the two clamping plates 24.

[0062] Secondly, the operator manually rotates the threaded rod 53 to adjust the position of the strip-shaped brush 52, so that the strip-shaped brush 52 can completely cover the inner bottom wall of the crucible in the subsequent process, then the telescopic section of the second hydraulic rod 42 is extended to drive the rotating cylinder 5 to move upward to the inside of the crucible through the supporting plate 4, until the rotating cylinder 5 drives the strip-shaped brush 52 to abut against the inner bottom wall of the crucible.

[0063] Thirdly, the telescopic section of the electric push rod 633 is extended to drive the driving link 631 to move upward, the driving link 631 drives the moving plate 61 to move away from the axis of the rotating cylinder 5 through the hinged plate 632, so that the moving plate 61 drives the brush blocks 62 thereon to abut against the inner side wall of the crucible, the uppermost brush block 62 can abut against the arc-shaped wall at the junction of the inner bottom wall and the inner side wall of the crucible, then the execution motor 41 is started to drive the rotating cylinder 5 to start rotating, and the brush blocks 62 and the strip-shaped brush 52 rotate synchronously to brush and wash the inner wall of the crucible.

[0064] Fourth step, the impurities brushed off by the bristle block 62 fall under the action of gravity into the receiving frame 651 on the inner side of the corresponding conical ring 65.

[0065] Fifth step, the telescopic section of the intermittent telescopic electric push rod 633 is retracted, the bristle block 62 moves towards the axis of the rotating cylinder 5, and the boss 647 on the driving rod 631 moves downwards at the same time. When the boss 647 touches the linkage plate 644, it continues to move downwards, and the boss 647 pushes the linkage plate 644 to rotate. The No. 2 notch 646 on the linkage plate 644 moves downwards, and the No. 1 notch 645 moves upwards, so that the linkage plate 644 drives all the moving rings 641 to move upwards synchronously through the sliding plate 643. The moving rings 641 move upwards, and the combs 642 are inserted into the bristles of the bristle block 62. Then, the telescopic section of the electric push rod 633 is retracted, so that the combs 642 comb the bristle block 62, so that the combs 642 remove the impurities stuck in the bristle block 62 and the end of the bristle block 62. The removed impurities fall onto the conical ring 65, and then the telescopic section of the electric push rod 633 is extended again, so that the boss 647 moves upwards, and the bristle block 62 continues to brush the crucible. Through the rotary elastic force of the torsional spring and the gravity of the combs 642, the sliding plate 643, and the moving rings 641, the linkage plate 644 is rotated to the initial position, and the combs 642 are synchronously moved to the initial position.

[0066] Sixth step, the rotating cylinder 5 drives the arc-shaped pry plate 73 to move to contact the stubborn impurities. The stubborn impurities will block the arc-shaped pry plate 73, so that the sliding plate 72 rotates in the opposite direction relative to the rotating cylinder 5 along the rotating direction of the rotating cylinder 5. The sliding plate 72 drives the moving rod 713 to move along the trajectory of the guide groove 712, and the moving rod 713 stretches the tension spring. As the arc-shaped pry plate 73 gradually scoops the stubborn impurities, the degree of stretching of the tension spring gradually increases, so that the pushing force of the arc-shaped pry plate 73 on the stubborn impurities gradually increases, and finally the arc-shaped pry plate 73 completely removes the stubborn impurities.

[0067] Eighth step, when the moving rod 713 moves along the trajectory of the guide groove 712, under the guidance and limitation of the guide groove 712, the moving rod 713 drives the sliding plate 72 to move towards the axis of the rotating cylinder 5, and the sliding plate 72 drives the arc-shaped pry plate 73 to move synchronously. The top plate member 741 is limited by the arc-shaped groove 51 and does not move with the sliding plate 72, so that the top plate member 741 moves away from the axis of the rotating cylinder 5 relative to the sliding plate 72. The top plate member 741 pushes the side of the arc-shaped pry plate 73 that contacts the stubborn impurities (i.e. the side of the arc-shaped pry plate 73 away from the corresponding top plate member 741) to deflect towards the axis of the rotating cylinder 5, so that the arc-shaped pry plate 73 scoops and prys the stubborn impurities at the same time, increasing the removal effect of the stubborn impurities.

[0068] In the ninth step, after the same height position of the crucible is continuously brushed for a period of time, the telescopic section of the second hydraulic rod 42 is intermittently retracted to drive the rotating cylinder 5 to move downward, so that the rotating cylinder 5 drives the bristle block 62 to comprehensively brush the side wall of the crucible.

[0069] Although the embodiments of the present application have been shown and described above, it should be understood by those skilled in the art that the above embodiments are exemplary and cannot be construed as limiting the present application, and those skilled in the art can make changes, modifications, replacements and variations to the above embodiments within the scope of the present application, which are still covered by the protection scope of the present application.
