Description

Technical Field

[0001] The utility model belongs to the technical field of pumps, and particularly relates to a chemical cleaning pump. Background Technique

[0002] A chemical cleaning pump is a highly efficient, high-pressure and energy-saving cleaning device, which is used for cleaning heat exchangers or reaction kettles and various pipelines in industries such as chemical plants, thermal power plants, sugar mills and paper mills. It can also be used for cleaning sand from castings. By configuring accessories, it can also be used for water sandblasting, thus overcoming the disadvantages of environmental pollution and affecting human health caused by air spraying noise of high-pressure cleaning pumps.

[0003] After some valve supporting production equipment has been used for a long time, a large amount of oil stains and impurities will be generated on its surface and internal pipelines. The oil stains and impurities need to be rinsed with chemical agents sprayed by a chemical cleaning pump. Since some chemical agents are in granular form, after being soaked in the cleaning liquid, they are not completely melted, resulting in being sucked into the interior of the cleaning pump and easily causing damage to the impeller blades inside the cleaning pump.

[0026] As Figures 1 to 4 shown, a chemical cleaning pump includes:

[0027] A pump unit 1 and a refinement cylinder 3. The refinement cylinder 3 is assembled to the end of the inlet pipe 102 of the impeller pump 101 in the pump unit 1 through an elbow 2. A suction pipe 301 is provided on the refinement cylinder 3. The inlet of the suction pipe 301 is located outside the refinement cylinder 3, and the outlet is located inside the refinement cylinder 3. A cylinder cover 303 is provided at the top of the refinement cylinder 3. The suction pipe 301 can be connected to an external water delivery pipe. When the pump unit 1 works, the impeller pump 101 can suck the cleaning liquid into the refinement cylinder 3 through the suction pipe 301, and then introduce it into the impeller pump 101 through the elbow 2.

[0028] A driving assembly is rotatably arranged between the bottom of the cylinder cover 303 and the inner hole of the drain pipe 302 of the refinement cylinder 3. The driving assembly includes a mounting shaft 401. The top end of the mounting shaft 401 is clamped in the stabilizing sleeve 304 at the bottom of the cylinder cover 303, and the bottom end of the mounting shaft 401 is clamped on the stabilizing frame 305 in the drain pipe 302, so as to rotatably mount the mounting shaft 401 between the bottom of the cylinder cover 303 and the inner hole of the drain pipe 302 of the refinement cylinder 3. An impeller 402 is provided on the mounting shaft 401. The outlet of the suction pipe 301 is aligned with the impeller 402. When the cleaning liquid is sucked into the refinement cylinder 3 through the suction pipe 301, the cleaning liquid can impact on the impeller 402, thereby causing the mounting shaft 401 to rotate.

[0029] Abrasive component, the abrasive component includes a fixed abrasive body 501 and a movable abrasive body 502. The fixed abrasive body 501 is arranged at the inner bottom of the refining cylinder 3, and the movable abrasive body 502 is arranged on the mounting shaft 401 of the driving component. The top of the fixed abrasive body 501 is in contact with the bottom of the movable abrasive body 502, and grinding grooves 503 are arranged on both the top of the fixed abrasive body 501 and the bottom of the movable abrasive body 502. After the cleaning liquid is inhaled into the refining cylinder 3 through the water suction pipe 301, the chemical agent particles in the cleaning liquid can enter the contact area between the top of the fixed abrasive body 501 and the bottom of the movable abrasive body 502 through the grinding grooves 503. During the rotation of the movable abrasive body 502, the chemical agent particles can be ground and refined at the contact area between the fixed abrasive body 501 and the movable abrasive body 502. And a leakage hole 506 is arranged in the middle of the fixed abrasive body 501, and the leakage hole 506 is aligned with the inner hole of the drain pipe 302. The ground and refined chemical agent particles can flow into the leakage hole 506 and be discharged into the drain pipe 302 and then enter the elbow 2. A plurality of flow channels 504 are arranged in an array on the movable abrasive body 502, and the bottom outlet of the flow channel 504 is aligned with the inner hole of the drain pipe 302. The cleaning liquid inhaled into the refining cylinder 3 can flow into the leakage hole 506 through the flow channels 504 and be discharged into the drain pipe 302 and then enter the elbow 2. Finally, the cleaning liquid and the refined chemical agent are inhaled into the impeller pump 101, preventing the coarse chemical agent particles from being inhaled into the impeller pump 101 with the cleaning liquid, thereby reducing the impact damage to the components in the impeller pump 101.

[0030] A protective net cover 505 is arranged at the top inlet of the flow channel 504. The arranged protective net cover 505 can prevent coarse chemical agent particles from entering the flow channel 504.

[0031] Screw holes 6 are arranged on the circumferential side wall of the fixed abrasive body 501. Screws 7 are jointly screwed into the corresponding parts of the circumferential side wall of the refining cylinder 3 in the screw holes 6. By arranging the screws 7, the fixed abrasive body 501 can be fixedly installed at the inner bottom of the refining cylinder 3 to prevent the fixed abrasive body 501 from rotating.
