The use of the wear-resistant and corrosion-resistant rubber-lined slurry pump as claimed in claim 1, wherein: firstly, in order to ensure the sealing performance of the equipment, a stuffing box 5 and an auxiliary impeller 12 are arranged in a pump body 7, the sealing performance of the pump body 7 is effectively ensured under the action of the stuffing box 5 and the auxiliary impeller 12, liquid can be prevented from flowing out during operation under the pressure generated by the auxiliary impeller 12, a water seal ring 6 is arranged between the stuffing box 5 and the auxiliary impeller 12, the water seal ring 6 and the stuffing box 5 are mutually matched to prevent external air from entering, and meanwhile, external impurities can be prevented from entering, and the use efficiency of the equipment is increased; then, after the equipment is placed at a specified position, the equipment is fixedly installed, the connecting seat 101 is placed above a hole which is drilled in advance, the position of the connecting seat 101 is adjusted, the anti-skid pad 104 is overlapped with the hole, the equipment is conveniently installed at the specified position, the fixing bolt 102 is screwed into the anti-skid pad 104 to fix the equipment, the anti-skid pad 104 is connected to the bottom of the connecting seat 101, the phenomenon that the equipment slides when being fixed to cause installation deviation can be avoided, the installation stability is increased, and the working efficiency of the equipment is improved; when the equipment is required to be connected with a motor for use, the equipment is connected with the motor through a right limiting seat 303 and a left limiting seat 301, the right limiting seat 303 is connected to one side of the bearing 4, the output end of the motor penetrates through the inside of the left limiting seat 301, the fixture block 302 is connected to the periphery of the outside of the right limiting seat 303, the fixture block 302 is placed inside the clamping groove 305, so that the equipment is quickly connected with the motor, a sealing ring 304 is arranged at the joint of the left limiting seat 301 and the right limiting seat 303, the use tightness of the equipment is improved, and multiple groups of the fixture block 302 and the clamping groove 305 are arranged, so that the stability during connection is improved, and the convenience of the equipment is improved; then, after the equipment is used, the equipment is placed in the air for a long time, the top of the short pipe 8 is open, dust and other impurities easily enter the short pipe 8, so that normal use of parts in the pump body 7 is influenced, after the equipment is used, the cover plate 901 blocks the opening of the short pipe 8, one side of the bottom of the cover plate 901 is connected with an upper connecting rod 902, the upper connecting rod 902 is placed in a fixed seat 903, the bottom end in the fixed seat 903 is connected with a lower connecting rod 904, the lower connecting rod 904 is movably hinged with a pull rod 905, one side of the lower connecting rod 904 is connected with a limiting spring 906, the pull rod 905 is pulled outwards and then rotates upwards, the lower connecting rod 904 is clamped at the bottom of the upper connecting rod 902 under the action of the limiting spring 906, the cover plate 901 is fixed, the structure is simple, the;

finally, when the first blade 1102 and the second blade 1103 connected to the outside of the chassis 1104 are used for operation, the second blade 1103 is lower than the first blade 1102, the second blade 1103 and the first blade 1102 are connected in a staggered manner outside the chassis 1104, the first blade 1102 is in an inverted L-shaped form, the lift during operation is improved, less resources are utilized, the utilization of the resources is saved, and a plurality of groups of flow channel holes are formed in the inverted L-shaped position of the first blade 1102, so that the flowing property of liquid is improved.
