Technical Field

[0001] The utility model relates to the technical field of slurry pumps, in particular to a slurry delivery pump. Background Art

[0002] A slurry pump is a pump specially designed to transport high-viscosity, solid particle-containing or corrosive media. The slurry pump includes a vertical, single-stage, single-suction cantilever submersible pump, which is suitable for transporting media containing solid particles. The pump shaft has no bearings in the submerged part, and the depth of immersion in the medium is adjustable.

[0003] When selecting a slurry pump, the viscosity of the slurry, the size and concentration of solid particles, and the chemical properties must be considered first. Currently, most slurry pumps will select a slurry pump with a suitable speed according to the viscosity of the slurry being transported. Since the speed of the slurry pump is fixed, when transporting slurries of different viscosities, it is necessary to replace the delivery pump with a suitable speed, which increases the cost of use. For this reason, a slurry delivery pump is proposed. Utility Model Content

[0024] The present invention will be further described below in conjunction with specific embodiments. However, people familiar with the art should understand that the detailed description given here in conjunction with the drawings is for better explanation, and the structure of the present invention must go beyond these limited embodiments. For some equivalent replacement solutions or common means, they will not be described in detail herein, but they still fall within the scope of protection of this application.

[0025] Figures 1 to 6 This is the best embodiment of the present invention, Figures 1 to 6 The utility model is further described.

[0026] like Figures 1 to 6As shown, the slurry conveying pump includes a mounting plate 1, on the upper side of which a motor 4 and a pump body 5 are fixedly mounted. A feed pipe 501 and a discharge pipe 502 are respectively provided on the outside of the pump body 5, and both the feed pipe 501 and the discharge pipe 502 are connected to the pump body 5. 706 and the third input gear 707. The first output gear 701, the second output gear 702, and the third output gear 703 are respectively engaged with the first input gear 705, the second input gear 706 and the third input gear 707. The support assembly 2 includes a fixed shell 201, a support seat 202, an input shaft 203 and an output shaft 204. The support seat 202 is arranged on the upper side of the mounting plate 1 and is located between the motor 4 and the pump body 5. The fixed shell 201 is arranged on the support seat 202. The input shaft 203 and the output shaft 204 are respectively rotatably mounted on the fixed shell 201. The output gear 701, the second output gear 702 and the third output gear 703 are connected to the output shaft 204, and the first input gear 705, the second input gear 706 and the third input gear 707 are connected to the input shaft 203; the adjustment component 6 is arranged inside the connecting mechanism, for adjusting the output speed of the motor 4, the adjustment component 6 includes a sliding rod 601 and a plurality of connecting blocks 603, the connecting blocks 603 are slidably sleeved outside the sliding rod 601, and the connecting blocks 603 are connected to the first input gear 705, the second input gear 706 and the third input gear 707. Specifically, the mounting plate 1 provides support for the motor 4, the connecting mechanism and the pump body 5 to ensure stability during use. When in use, the power output of the motor 4 is transmitted through the connecting mechanism to ensure the stability of the pump body 5 during use. When the concentration of the conveyed slurry changes, the power output of the motor 4 is adjusted through the connecting mechanism to ensure the stability of the pump body 5 when conveying different slurries.

[0027] like Figures 1 to 6 As shown, one end of the input shaft 203 and the output shaft 204 are both provided with a coupling 8. The coupling 8 at the end of the input shaft 203 is connected to the output end of the motor 4, and the coupling 8 at one end of the output shaft 204 is connected to the input end of the pump body 5. A groove is provided at the other end of the input shaft 203, and a plurality of sliding grooves 205 are provided on the side of the input shaft 203. The sliding grooves 205 pass through the input shaft 203, and the sliding grooves 205 are connected to the grooves. Specifically, when the pump body 5 is used to transport the slurry, the power output by the motor 4 is transmitted to the inside of the pump body 5 through the cooperation of the output shaft 204, the input shaft 203 and the rotating assembly 7, thereby ensuring the stability of the pump body 5 during use.

[0028] More specifically, the input shaft 203 and the output shaft 204 are connected to the motor 4 and the pump body 5 through the coupling 8, so that when the pump body 5 is blocked, the rotating component 7 and the motor 4 are protected to avoid damage to the motor 4 and the rotating component 7 caused by hard connection. The coupling 8 is a prior art and will not be explained in detail here.

[0029] like Figures 1 to 6 As shown, the diameters of the first output gear 701, the second output gear 702, and the third output gear 703 decrease in sequence, while the sizes of the first input gear 705, the second input gear 706, and the third input gear 707 increase in sequence. The inner walls of the first input gear 705, the second input gear 706, and the third input gear 707 are each provided with a plurality of connecting grooves 708. Specifically, the first output gear 701, the second output gear 702, and the third output gear 703 decrease in size in opposite directions to the first input gear 705, the second input gear 706, and the third input gear 707, thereby providing different speeds and torques when engaged. The first output gear 701, the second output gear 702, the third output gear 703, the first input gear 705, the second input gear 706, and the third input gear 707 have the same module.

[0030] like Figures 1 to 6 As shown, a fixing ring 206 is further provided on the outside of the input shaft 203, and the fixing ring 206 abuts against the first input gear 705. A limiting component 3 is also provided on the outside of the fixed shell 201. The limiting component 3 is used to fix the position of the adjustment component 6. Specifically, the fixing ring 206 limits the first input gear 705 to avoid the position deviation of the first input gear 705 during engagement, resulting in a situation where engagement cannot occur, thereby ensuring stability during use.

[0031] like Figures 1 to 6As shown, a connecting column 604 is further provided on the outside of the sliding rod 601, and the sliding rod 601 slides inside the groove. A plurality of limiting rings 602 are provided on the outside of the sliding rod 601, and a connecting block 603 is provided at one end of the sliding rod 601, and the connecting block 603 slides inside the sliding groove 205, and the connecting block 603 is adapted to the connecting groove 708. A connecting column 604 is provided on the other end of the sliding rod 601. Specifically, the connecting block 603 is adjusted in position by pulling the sliding rod 601, so that the connecting block 603 can select any one of the first input gear 705, the second input gear 706 and the third input gear 707 to rotate synchronously with the input shaft 203, thereby adjusting the speed of the output shaft 204. When the slurry viscosity is high, the sliding rod 601 is first pulled to move inside the groove by the connecting column 604. When the sliding rod 601 moves, the connecting block 603 is driven to slide along the sliding groove 205 to the first input gear 705. While sliding, the connecting block 603 is inserted into 707, so that the third input gear 707 rotates synchronously with the input shaft 203. Since the size of the third input gear 707 is larger than that of the third output gear 703, the rotation speed of the input shaft 203 is increased to ensure the slurry delivery rate, and the torque and rotation speed can be adjusted according to the concentration of the slurry, thereby increasing the compatibility during slurry delivery.

[0032] More specifically, the length of the connecting block 603 and the connecting groove 708 along the axis of the sliding rod 601 is the same, and the spacing of the limiting ring 602 is equal to the thickness of the first input gear 705, the second input gear 706 and the third input gear 707, so that the position of the connecting block 603 is prompted when the first input gear 705, the second input gear 706 and the third input gear 707 are selected to ensure stability during use.

[0033] like Figures 1 to 6As shown, specifically, the limiting assembly 3 includes a fixed shaft 301, two rotating plates 302 and a connecting piece 303. The rotating plate 302 rotates on the outside of the fixed shaft 301. A slot is provided on one side of the opposite surface of the rotating plate 302, and the slot is adapted to the limiting ring 602. The connecting piece 303 is connected to the rotating plate 302, and the two connecting pieces 303 are fixed by bolts, thereby realizing the axial limitation of the fixed shaft 301 by the two connecting pieces 303.

[0034] The rotating plate 302 rotates around the fixed axis 301. When in use, the position of the sliding rod 601 is fixed by the cooperation of the card slot and the limiting ring 602 to prevent the connection block 603 from moving during use. At the same time, the position of the connection block 603 is detected by the relative position of the card slot and the limiting ring 602 to further ensure stability during use.

[0035] When the connecting column 604 is used to pull the sliding rod 601 to move axially and then move the position of the connecting block 603, it is necessary to operate in the shutdown state, that is, to adjust when the motor 4 is not working.

[0036] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation thereto. Any person skilled in the art may utilize the above disclosure to modify or remodel the present invention into equivalent embodiments. However, any simple modification, equivalent variation, or modification of the above embodiment that does not depart from the technical content of the present invention and is based on the technical essence of the present invention shall still fall within the scope of protection of the present invention.
