[0002] A slurry pump refers to a machine that can increase the energy of solid-liquid mixed medium by centrifugal force (rotation of the impeller of the pump), and convert electrical energy into kinetic energy and potential energy of the medium.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0031] In order to solve the problem that the rotary cutting effect of the second knife tooth is limited in the prior art, and large particles that cannot be cut in time are easily jammed in the gap between the first knife tooth and the second knife tooth, please refer to Figures 1-6 The technical solutions provided by the present embodiment are as follows:

[0032] A slag slurry pump with an inner rotary cutting structure to prevent blockage under liquid, comprising a flat base 1, the upper surface of the flat base 1 is fixedly connected with a first motor 11 and a pump shell 2, the output end of the first motor 11 penetrates the pump shell 2, and the position of the first motor 11 in the pump shell 2 is fixedly connected with an inner rotary cutting part 3, one end of the pump shell 2 is provided with an inlet pipe 21, the inner rotary cutting part 3 is arranged in the inlet pipe 21, a first rotary cutting frame 31 and a second rotary cutting frame 32 are movably connected with the inner wall of the inlet pipe 21, a limiting sliding groove matched with the first rotary cutting frame 31 and the second rotary cutting frame 32 is formed in the inner wall of the inlet pipe 21, a turbine 22 is arranged in the pump shell 2, and the center line of the turbine 22 is fixedly connected with a main shaft 34.

[0033] Specifically, the inlet pipe 21 is used for the entry of slurry, the first motor 11 drives the turbine 22 to rotate through the main shaft 34.

[0034] The upper end of the pump shell 2 is provided with an outlet pipe 23, the outlet pipe 23 has an L-shaped structure, the outlet is arranged on the horizontal pipe, the top of the vertical pipe is a closed structure, the upper end of the outlet pipe 23 is provided with a second motor 231, the output end of the second motor 231 penetrates the outlet pipe 23, and the output end of the second motor 231 is fixedly connected with a stirring rod 232.

[0035] The stirring rod 232 is fixedly connected with a spiral blade 2321, and the diameter of the spiral blade 2321 gradually decreases from top to bottom.

[0036] Specifically, the diameter of the lower end of the spiral blade 2321 is small, and the spiral blade 2321 occupies a small volume of the slurry outlet pipe 23. When the slurry flows into the slurry outlet pipe 23, the spiral blade 2321 will not cause blockage of the slurry, and a certain buffer space is provided for the slurry. Meanwhile, the stirring rod 232 rotates under the action of the second motor 231, and drives the spiral blade 2321 to rotate, so that the slurry can be taken out of the slurry outlet pipe 23. The spiral blade 2321 simultaneously plays a role of stirring and conveying, and the output slurry can be uniformly and evenly discharged, so as to avoid blockage caused by large or small discharge amount of the slurry in the pipeline.

[0037] The inner rotary cutting component 3 comprises a first rotary cutting frame 31, a second rotary cutting frame 32, an oblique cutting frame 33, a main rotating shaft 34 and an oblique shaft 35. The oblique cutting frame 33 is arranged between the first rotary cutting frame 31 and the second rotary cutting frame 32. After rotary cutting by the first rotary cutting frame 31, the slurry is cut or extruded by the oblique cutting frame 33, and finally rotary cut by the second rotary cutting frame 32. Through multi-layer cutting, multiple crushing is realized. One end of the main rotating shaft 34 is fixedly connected with the output end of the first motor 11, and the other end of the main rotating shaft 34 is fixedly connected with the oblique shaft 35. The oblique shaft 35 is provided with the first rotary cutting frame 31 and the second rotary cutting frame 32 at two ends thereof, and the oblique cutting frame 33 is sleeved on the oblique shaft 35.

[0038] The first rotary cutting frame 31 and the second rotary cutting frame 32 are provided with a connecting frame 311. The connecting frame 311 is fixedly connected with the end of the oblique shaft 35. When the main rotating shaft 34 rotates, the oblique shaft 35 rotates, and the oblique shaft 35 drives the first rotary cutting frame 31 and the second rotary cutting frame 32 connected therewith to rotate simultaneously, so as to cut and crush the large particle slurry.

[0039] The center position of the connecting frame 311 is not on the same vertical plane as the edge position. The center position of the connecting frame 311 arranged on the first rotary cutting frame 31 protrudes towards the first motor 11. The connecting frame 311 arranged on the first rotary cutting frame 31 is inclined, and the rotating process can simultaneously push the slurry inward, so as to reduce the loss of suction force caused by the filtering operation. The center position of the connecting frame 311 arranged on the second rotary cutting frame 32 protrudes away from the first motor 11. The connecting frame 311 arranged on the second rotary cutting frame 32 is inclined, and plays a guiding role, so as to divide the slurry to the second rotary cutting frame 32, and the second rotary cutting frame 32 plays a role of secondary cutting on the slurry.

[0040] The first rotary cutting frame 31 and the second rotary cutting frame 32 are further provided with a rotary cutting knife 312. The end of the rotary cutting knife 312 away from the first rotary cutting frame 31 or the second rotary cutting frame 32 is inclined towards the first motor 11. The rotary cutting knife 312 is inclined, and the rotating process can simultaneously push the slurry inward, so as to reduce the loss of suction force caused by the filtering operation.

[0041] The oblique cutting frame 33 comprises a support plate 331, an outer ring 332, a scraper 333, a crushing knife 334 and an inner sleeve 335. The outer wall of the outer ring 332 is fixedly connected with the scraper 333. Whether the outer ring 332 rotates or swings, it can drive the scraper 333 to move along the inner wall of the pump shell 2, scrape off the slurry adhering to the inner wall of the pump shell 2, and avoid blockage. One end of the support plate 331 is fixedly connected with the inner sleeve 335, the inner sleeve 335 is sleeved with the oblique shaft 35, the other end of the support plate 331 is fixedly connected with the outer ring 332, and the support plate 331 is provided with a blade groove 3311. The crushing knife 334 is installed in the blade groove 3311.

[0042] Specifically, when the oblique shaft 35 rotates, the oblique cutting frame 33 has two movement modes. The first movement mode: the friction between the oblique shaft 35 and the inner sleeve 335 is greater than the resistance generated by the slurry to the rotation of the oblique cutting frame 33. At this time, the oblique shaft 35 synchronously drives the inner sleeve 335 to rotate. Correspondingly, the oblique cutting frame 33 rotates with the oblique shaft 35. The oblique cutting frame 33 obliquely cuts the slurry, and the crushing knife 334 crushes the slurry particles. The second movement mode: the friction between the oblique shaft 35 and the inner sleeve 335 is less than the resistance generated by the slurry to the rotation of the oblique cutting frame 33. The oblique shaft 35 cannot drive the inner sleeve 335 to rotate. The oblique shaft 35 and the inner sleeve 335 move relatively. After the oblique shaft 35 rotates, the oblique direction of the oblique shaft 35 changes, which can drive the inner sleeve 335 to change the oblique direction. Therefore, the oblique cutting frame 33 controls the outer ring 332 to swing with the center fulcrum of the inner sleeve 335. The outer ring 332 extrudes the slurry in the pump shell 2, and the crushing knife 334 crushes the large particles.

[0043] In actual operation, the movement mode of the oblique cutting frame 33 is closely related to the state of the slurry. The oblique cutting frame 33 will also continuously switch between the two movement modes to crush the large particle slurry, facilitate the passage of the slurry through the pump body, and avoid blockage.

[0044] The crushing knife 334 is installed in the blade groove 3311 through bolts. The crushing knife 334 is provided with an inclined groove 3341 to reduce the resistance to the slurry and improve the crushing effect. The crushing knife 334 is a detachable structure for convenient replacement.

[0045] In order to better show the use process of the anti-blocking submerged slurry pump with an inner rotary cutting structure, the present embodiment proposes a use method of the anti-blocking submerged slurry pump with an inner rotary cutting structure, comprising the following steps:

[0046] Step one: place the anti-blocking submerged slurry pump on the flat base 1, start the first motor 11, and control the main shaft 34 to rotate. The main shaft 34 synchronously drives the turbine 22 and the oblique shaft 35 to rotate. The turbine 22 generates suction to suck the slurry into the slurry inlet pipe 21.

[0047] Step two: the oblique shaft 35 drives the first rotary cutting frame 31 and the second rotary cutting frame 32 to rotate, and large particle slurry is cut and crushed, and the slurry passing through the oblique cutting frame 33 is crushed again under the action of rotary cutting and extrusion cutting of the oblique cutting frame 33;

[0048] Step three: the treated slurry is discharged through the slurry outlet pipe 23, and in the discharging process, the second motor 231 drives the spiral blade 2321 to rotate through the stirring rod 232, and the spiral blade 2321 simultaneously plays the role of stirring and conveying, and the slurry is discharged at a uniform speed, so that the pipe is prevented from being blocked due to different conveying speeds.
