Description

Technical Field

[0001] The invention belongs to the technical field of slurry pumps, and in particular relates to a slurry pump with a shock-absorbing function. Background Art

[0002] Slurry pumps convey a mixture of solid particles containing slag and water. In principle, slurry pumps are a type of centrifugal pump. They convey slurry by means of the rotation of the pump's impeller. They are mainly used in industries such as mining, power plants, dredging, metallurgy, chemicals, building materials, and petroleum. Slurry pumps include vertical slurry pumps and horizontal slurry pumps. Since the use environment of slurry pumps is relatively complex, it is necessary to set a shock-absorbing structure between the base and the bottom plate of the slurry pump to reduce the vibration of the pump body and motor during movement, and to prevent long-term vibration from causing the structure to loosen and affect the service life.

[0003] Most of the existing shock-absorbing structures install multiple spring shock absorbers between the base and the bottom plate to achieve the shock-absorbing effect. However, due to the complex environment around the slurry pump, if the spring of the spring shock absorber is directly exposed to the outside, and if gravel or other particles and debris enter between the spring coils of the spring, it will not only affect the efficient and stable shock-absorbing effect of the spring shock absorber on the slurry pump, but also easily cause rust damage to the spring. Summary of the invention

[0007] Furthermore, a lifting chamber is provided inside the support rod, a through hole is provided on the rubber sliding plug, and the through hole is connected to the lifting chamber, a through hole is provided downwardly through the bottom of the protective tube, and the through hole is aligned with the through hole, a notch groove is provided on the support pad, a semi-threaded bolt is vertically inserted at the center of the shock-absorbing spring inside the protective tube, the head of the semi-threaded bolt passes through the through hole upward and is located in the lifting chamber, and the bottom of the semi-threaded bolt passes through the through hole and is connected to an internal threaded ring, and the internal threaded ring is located in the notch groove.

[0008] Furthermore, the notch of the notch groove faces the outer side surface of the base, the outer ring surface of the internal threaded ring is designed in a gear-like shape, and symmetrical spur racks are horizontally installed in the notch groove along its length direction, and the symmetrical spur racks are in meshing contact with the teeth of the outer ring surface of the gear-shaped internal threaded ring, and the symmetrical spur racks are respectively installed on the two side walls of the notch groove through two groups of adjusting sliding components.

[0009] Furthermore, the adjustment sliding assembly includes a supporting strip, a T-shaped strip, an I-shaped strip, a spring support, an adjustment bolt, a guide cylinder and a supporting guide rod. The two side walls of the notch groove are horizontally provided with adjustment grooves along the length direction thereof, and the height of the adjustment groove is greater than the thickness of the spur rack. A supporting strip is installed on the back of the spur rack, and the supporting strip is located in the adjustment groove. The upper and lower surfaces of the supporting strip are penetrated with T-shaped slide grooves along the length direction thereof. The T-shaped strip is slidably inserted in the T-shaped slide groove located at the upper side, and the T-shaped strip located at the lower side is inserted in the T-shaped slide groove. An I-shaped strip is slidably inserted in the T-shaped slide groove, and a plurality of spring support members are connected to the lower surface of the I-shaped strip along its length direction, and the bottom of the spring support member is connected to the bottom of the adjusting groove, and an adjusting bolt is vertically threadedly connected to the groove opening of the upper groove wall of the adjusting groove near the notch groove, and the bottom end of the adjusting bolt is connected to the vertical bar of the T-shaped strip, and a guide cylinder is vertically fixed to the upper groove wall of the adjusting groove near the tail of the notch groove, and a supporting guide rod is slidably inserted in the guide cylinder, and the bottom end of the supporting guide rod is also connected to the vertical bar of the T-shaped strip.

[0014] The present invention has the following beneficial effects:

[0015] 1. The present invention cooperates with the rubber sliding plug and the shock-absorbing spring that slide in the protective tube. When the base plate is vibrated by the driving device or the pump body, the rubber sliding plug will slide up and down in the protective tube and squeeze the shock-absorbing spring. While the shock-absorbing spring plays a role in shock absorption, the rubber sliding plug will also have a certain shock-absorbing effect, thereby effectively offsetting the vibration generated by the driving device and the pump body of the slurry pump when they are working. At the same time, since the shock-absorbing spring is hidden inside the protective tube, it will not be affected by the influence of the surrounding environment of the slurry pump, and gravel or other impurities will be adhered between the spring coils of the shock-absorbing spring, which will not only affect the normal and safe shock absorption of the shock-absorbing spring, but also cause rust damage to the shock-absorbing spring.

[0016] 2. The present invention cooperates with the teeth on the outer ring surface of the internal threaded ring in the notch groove and the spur rack. The operator only needs to push one of the spur racks horizontally to make it slide horizontally in the notch groove, so as to drive the internal threaded ring to twist at the bottom of the protective tube, thereby facilitating the adjustment of the length of the screw rod of the semi-threaded bolt extending out of the bottom of the protective tube, so as to compress or release the shock-absorbing spring. The spur rack is supported in the notch groove by an adjusting sliding assembly, which not only fixes the adjusted spur rack so that it is always meshed with the teeth on the outer ring of the internal threaded ring, but also fixes the internal threaded ring to prevent it from rotating. When the spur rack needs to slide, the adjusting sliding assembly can also play a guiding and supporting role for the sliding spur rack to prevent the spur rack from falling or tilting during sliding.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] 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.

[0035] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0036] See also Figure 1-Figure 6 As shown, the present invention is a slurry pump with a shock absorbing function, comprising a driving device 1 and a pump body 2, wherein the driving device 1 and the pump body 2 are connected via a coupling, and characterized in that it also comprises a base 3 and a bottom plate 4, wherein the driving device 1 and the pump body 2 are both fixedly mounted on the bottom plate 4, and a plurality of protective shock absorbing mechanisms 5 are arranged between the bottom plate 4 and the base 3;

[0037] The protective shock-absorbing mechanism 5 comprises a supporting pad 51, a protective tube 52, a shock-absorbing spring 53, a rubber plug 54, a supporting rod 55 and a threaded rod 56. The plurality of supporting pads 51 are respectively fixed to the upper surface of the base 3, and a protective tube 52 is vertically fixed to the upper surface of the supporting pad 51. A shock-absorbing spring 53 is vertically installed in the protective tube 52, and a rubber plug 54 is installed on the upper end of the shock-absorbing spring 53. The rubber plug 54 is slidably arranged in the protective tube 52, and a supporting rod 55 is vertically connected to the upper end surface of the rubber plug 54. The top end of the supporting rod 55 extends out of the protective tube 52 and is installed with a threaded rod 56. The threaded rod 56 is fixedly connected to the bottom plate 4 by a nut.

[0038] Specifically, the present invention places the shock absorbing spring 53 into the protective tube 52, and the protective tube 52 is vertically fixed to the base 3 through the cooperation of the support pad 51 and the screw, and then the threaded rod 56 at the top end of the support rod 55 is inserted upward into the mounting hole opened on the bottom plate 4, and then the multiple sets of protective shock absorbing mechanisms 5 are sequentially installed on the base 3 and the bottom plate 4 through the cooperation of nuts and gaskets, and then through the cooperation of the rubber sliding plug 54 sliding in the protective tube 52 and the shock absorbing spring 53, when the bottom plate 4 is vibrated by the driving device 1 or the pump body 2, the rubber sliding plug 54 will move upward in the protective tube 52. The rubber plug 54 will also have a certain shock-absorbing effect when the shock-absorbing spring 53 plays a role in shock absorption, thereby effectively offsetting the vibration generated by the driving device 1 and the pump body 2 of the slurry pump when they are working. At the same time, since the shock-absorbing spring 53 is hidden inside the protective tube 52, it will not be affected by the influence of the surrounding environment of the slurry pump, and will not cause gravel or other impurities to adhere between the spring coils of the shock-absorbing spring 53, which will not only affect the normal and safe shock absorption of the shock-absorbing spring 53, but also cause rust damage to the shock-absorbing spring 53.

[0039] In this embodiment, a lifting chamber 551 is provided inside the support rod 55, a through hole is provided on the rubber plug 54, and the through hole is communicated with the lifting chamber 551, a through hole is provided downwardly through the bottom of the protective tube 52, and the through hole is aligned with the through hole, a notch groove 511 is provided on the support pad 51, a semi-threaded bolt 57 is vertically inserted at the center of the shock absorbing spring 53 inside the protective tube 52, the head of the semi-threaded bolt 57 passes through the through hole upward and is located in the lifting chamber 551, and the bottom of the semi-threaded bolt 57 passes through the through hole and is connected with an internal threaded ring 58, and the internal threaded ring 58 is located in the notch groove 511;

[0040] Specifically, in order to improve the shock-absorbing effect of the shock-absorbing spring 53 on the slurry pump, the elastic potential energy of the shock-absorbing spring 53 can be adjusted as needed. Therefore, when it is necessary to compress the shock-absorbing spring 53 in the protective tube 52 and reduce the elastic deformation, the internal threaded ring 58 in the notch groove 511 can be twisted to make the semi-threaded bolt 57 in the protective tube 52 slide downward in the through hole, thereby reducing the distance between the rubber sliding plug 54 and the bottom of the protective tube 52, so that the shock-absorbing spring 53 is in a compressed state in the protective tube 52. When the plug 54 continues to slide in the protective tube 52 due to the vibration, the unthreaded upper part of the semi-threaded bolt 57 slides through the through hole and is located in the lifting chamber 551. Therefore, it will not interfere with the normal sliding and shock absorption of the rubber sliding plug 54 in the protective tube 52. The reverse twisting of the internal threaded ring 58 can make the semi-threaded bolt 57 rise in the protective tube 52, so that the distance between the rubber sliding plug 54 and the bottom of the protective tube 52 is increased, thereby reducing the compression of the shock-absorbing spring 53 in the protective tube 52, so that it can fully reduce the shock of the slurry pump.

[0041] In this embodiment, the notch of the notch groove 511 faces the outer side surface of the base 3, the outer ring surface of the internal thread ring 58 is designed in a gear shape, and a symmetrical spur rack 6 is horizontally installed in the notch groove 511 along its length direction, and the symmetrical spur rack 6 is in meshing contact with the teeth of the outer ring surface of the gear-shaped internal thread ring 58, and the symmetrical spur rack 6 is respectively installed on the two side walls of the notch groove 511 through two sets of adjustment sliding components 7;

[0042] Specifically, since the screw head of the semi-threaded bolt 57 is inserted into the notch groove 511 and is located at the bottom of the protective tube 52, in order to facilitate the twisting of the internal thread ring 58 to adjust the length of the semi-threaded bolt 57 in the protective tube 52, the present invention symmetrically arranges spur racks 6 on both side walls of the notch groove 511, and the spur racks 6 are meshed with the teeth of the outer ring surface of the gear-shaped internal thread ring 58. Therefore, the operator only needs to push one of the spur racks 6 horizontally to make it slide horizontally in the notch groove 511, so as to drive the internal thread ring 58 to twist at the bottom of the protective tube 52, thereby It is convenient to adjust the length of the screw rod of the semi-threaded bolt 57 extending out of the bottom of the protective tube 52, so that it can compress or release the shock-absorbing spring 53; and the spur rack 6 is supported in the notch groove 511 by adjusting the sliding assembly 7, which not only fixes the adjusted spur rack 6 so that it is always engaged with the outer ring teeth of the internal thread ring 58, but also fixes the internal thread ring 58 to prevent the internal thread ring 58 from rotating. When the spur rack 6 needs to slide, the adjusting sliding assembly 7 can also play a guiding and supporting role for the sliding spur rack 6 to prevent the spur rack 6 from falling or tilting during sliding.

[0043] In this embodiment, the adjustment sliding assembly 7 includes a supporting strip 71, a T-shaped strip 72, an I-shaped strip 73, a spring support 74, an adjustment bolt 75, a guide cylinder 76 and a supporting guide rod 77. The two side walls of the notch groove 511 are horizontally provided with adjustment grooves 512 along the length direction thereof, and the height of the adjustment groove 512 is greater than the thickness of the spur rack 6. The supporting strip 71 is installed on the back of the spur rack 6, and the supporting strip 71 is located in the adjustment groove 512. The upper and lower surfaces of the supporting strip 71 are penetrated with T-shaped slide grooves 711 along the length direction thereof. The T-shaped strip 72 is slidably inserted in the T-shaped slide groove 711 located at the upper side, and the T-shaped strip 72 is slidably inserted in the T-shaped slide groove 711 located at the lower side. An I-shaped strip 73 is slidably inserted in the T-shaped slide groove 711, and a plurality of spring support members 74 are connected to the lower surface of the I-shaped strip 73 along its length direction, and the bottom of the spring support member 74 is connected to the bottom of the adjusting groove 512, and an adjusting bolt 75 is vertically threadedly connected to the notch of the notch groove 511 at the upper groove wall of the adjusting groove 512, and the bottom end of the adjusting bolt 75 is connected to the vertical bar of the T-shaped strip 72, and a guide cylinder 76 is vertically fixed to the upper groove wall of the adjusting groove 512 near the tail of the notch groove 511, and a support guide rod 77 is slidably inserted in the guide cylinder 76, and the bottom end of the support guide rod 77 is also connected to the vertical bar of the T-shaped strip 72;

[0044] When the cam 72 is in the closed position, the adjusting screw 75 is rotated to adjust the position of the adjusting screw 75 so that the adjusting screw 75 can move freely in the adjusting slot 512. When the cam 72 is in the closed position, the adjusting screw 75 is rotated to adjust the position of the adjusting screw 75 so that the adjusting screw 75 can move freely in the adjusting slot 512. When the cam 72 is in the closed position, the adjusting screw 75 is rotated to adjust the position of the adjusting screw 75.

[0045] When the spur rack 6 slides to the limit position and needs to be reset and continue to slide, the operator continues to twist the adjusting bolt 75 corresponding to the spur rack 6 that needs to be reset, so that it pushes the supporting strip 71 to slide downward in the adjusting groove 512 through the T-shaped strip 72, so that the spur rack 6 that needs to be reset slides downward and disengages the teeth on the outer ring surface of the internal threaded ring 58. Then the operator pushes or pulls the sliding spur rack 6 to reset it to its initial state, and then reversely twists the adjusting bolt 75, so that the supporting strip 71 rises under the elastic push of the multiple spring support members 74, so that the spur rack 6 continues to mesh with the teeth of the internal threaded ring 58 for transmission, and the supporting guide rod 77 at the notch on the rear side of the notch groove 511 slides in the guide cylinder 76, and the lifting and sliding supporting strip 71 can be suspended by the T-shaped strip 72, thereby facilitating the suspended support and meshing of the meshed spur rack 6.

[0046] When the length of the semi-threaded bolt 57 is adjusted, continue to twist the adjusting bolt 75 so that it drives the supporting strip 71 to slide upward to the top of the adjusting groove 512 through the T-shaped strip 72 to fit in the groove, so that it can fix the supporting strip 71, thereby facilitating the adjusted spur rack 6 to always be in a meshing state and fixed in the notch groove 511, thereby achieving stable and safe fixation of the internal thread ring 58 and the semi-threaded bolt 57, and preventing the internal thread ring 58 from rotating when the shock-absorbing spring 53 is in shock-absorbing operation, thereby affecting the tightening effect of the adjusted semi-threaded bolt 57.

[0047] In this embodiment, the outer end of the spur rack 6 is detachably connected to a push rod 78, and the push rod 78 extends out of the notch groove 511; specifically, the operator can install the push rod 78 to the outer end surface of the spur rack 6 by means of a threaded connection, so as to achieve horizontal pushing and sliding of the spur rack 6, thereby facilitating the twisting of the internal thread ring 58. When there is no need to push the spur rack 6 horizontally, the push rod 78 can be removed from the outer end of the spur rack 6.

[0048] In this embodiment, a sealing plate 8 is sealed and inserted at the outer notch of the notch groove 511, and the sealing plate 8 is threadedly connected to the push rod 78. A shielding plate 81 is horizontally installed inwardly on the upper surface of the sealing plate 8, and the shielding plate 81 shields the upper notch of the notch groove 511;

[0049] Specifically, after the length of the semi-threaded bolt 57 is adjusted, the push rod 78 is first removed from the outer end of the straight rack 6, and then the arc-shaped sealing plate 8 is sealed to the outer notch of the notch groove 511, and the shielding plate 81 will block the upper notch of the notch groove 511, and then the push rod 78 is threaded through the threaded hole of the sealing plate 8 and connected to the outer end surface of the straight rack 6, so as to facilitate the fixation of the arc-shaped sealing plate 8, so that the sealing plate 8 can block the outer notch of the notch groove 511, and the shielding plate 81 will block the upper notch of the notch groove 511. The upper notch is used for shielding to prevent the surrounding granular impurities from falling into the notch groove 511 when the slurry pump is working, which would affect the normal operation of the various structures of the adjustment sliding assembly 7; and when the spur rack 6 needs to be pushed horizontally normally, the operator will remove the pushing rod 78 at this time, and then remove the sealing plate 8 from the outer notch of the notch groove 511, and the shielding plate 81 will slide out from the upper notch of the notch groove 511, thereby facilitating the pushing of the spur rack 6 to be pushed horizontally in the notch groove 511, thereby achieving the length adjustment of the half-threaded bolt 57.

[0050] In this embodiment, the bottom of the shock absorbing spring 53 is connected to the bottom of the protective tube 52 through a rubber pad 59, the rubber pad 59 is sealingly sleeved on the semi-threaded bolt 57, and the protective tube 52 is filled with lubricating oil;

[0051] Specifically, the design of the rubber pad 59 can further achieve the shock-absorbing effect, and the lubricating oil filled in the protective tube 52 can lubricate and cool the frequently vibrating shock-absorbing spring 53 and the rubber sliding plug 54 that slides up and down, thereby preventing the shock-absorbing spring 53 from vibrating frequently in the protective tube 52 and the rubber sliding plug 54 from reciprocatingly rubbing inside the protective tube 52, thereby generating more heat and sliding wear. The filled lubricating oil will not leak from between the upper tube mouth of the protective tube 52 and the support rod 55, thereby not affecting the normal lubrication and cooling of the shock-absorbing spring 53 and the rubber sliding plug 54 that slides up and down by the lubricating oil.

[0052] In this embodiment, an oil storage cylinder 9 is installed on the outer cylinder wall of the protective cylinder 52, and the bottom of the oil storage cylinder 9 is connected to the protective cylinder 52 through a guide tube 91, and a liquid level gauge is arranged in the oil storage cylinder 9; specifically, when the shock-absorbing spring 53 in one of the protective cylinders 52 is vibrated, causing the rubber sliding plug 54 to slide back and forth in the protective cylinder 52, the lubricating oil in the protective cylinder 52 will produce a reciprocating compression flow, and then the lubricating oil will also flow back and forth into the oil storage cylinder 9 through the guide tube 91, and at this time the liquid level gauge will monitor the frequent changes in the liquid level of the lubricating oil in the oil storage cylinder 9, and then the operator can use the data of the large change in the oil liquid level monitored by the liquid level gauge to adjust the compression amount of the shock-absorbing spring 53 in the corresponding protective cylinder 52, so that the vibration generated during the operation of the slurry pump can be more accurately damped.
