Description
Technical Field
[0001] The utility model relates to the technical field of long-axis pumps, in particular to a long-axis pump used for transporting high-temperature liquids. Background Art
[0002] Long-shaft pumps, a type of centrifugal pump, are an improvement on the performance of submersible pumps. They are suitable for conveying a variety of corrosive media, including particles, high viscosity media, strong acids, alkalis, salts, and strong oxidants. They are widely used in industrial and mining enterprises such as water companies, sewage treatment plants, steel mills, and mines, as well as in municipal water supply and drainage, farmland irrigation, and flood control and drainage projects.
[0003] After searching, the prior art announcement number CN211778024U discloses a long-axis pump for transporting rainwater, including a long-axis pump body and a volute pump casing located at the bottom of the long-axis pump body. The long-axis pump body is provided with a pumping mechanism, and a filter cover is installed at the bottom of the long-axis pump body. The filter cover is provided with a crushing mechanism. The utility model uses the pumping mechanism located in the long-axis pump body to automatically pump rainwater. The magnetic float ball can detect the liquid level of rainwater to prevent the water pump from idling due to the low rainwater level. The crushing mechanism can crush the debris in the filter cover to prevent the pump flow pipeline from being blocked, making it easy to use.
[0004] However, after the long-axis pump of the utility model crushes the impurities, the impurities still flow in the pump. After long-term use, the crushed impurities still clog the inner wall of the impurity filter frame, and cleaning is also relatively difficult. Therefore, a long-axis pump for high-temperature liquid transportation is proposed to solve the above problems. Utility Model Content
[0005] In response to the shortcomings of the existing technology, the utility model provides a long-axis pump for high-temperature liquid transportation, which has the advantages of impurity crushing, cleaning and collection. It solves the problem that after the long-axis pump crushes the impurities, the impurities still flow in the pump, and the crushed impurities still cause blockage on the inner wall of the impurity filter frame after long-term use, and cleaning is also relatively difficult.
[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a long-axis pump for high-temperature liquid transportation, comprising a long-axis pump body, wherein a filtering and cleaning device for filtering impurities in the liquid is provided on the lower side of the long-axis pump body;
[0007] The filtering and cleaning device includes a driving motor fixedly mounted on the left end of the lower side of the long-axis pump body, a rotating shaft fixedly connected to the output end of the driving motor, a second gear fixedly sleeved on the outer wall of the lower side of the rotating shaft, a first gear meshingly connected to the outer side of the second gear, a rotating cylinder fixedly sleeved on the inner wall of the first gear, two cleaning brushes integrally connected to the inner wall of the rotating cylinder, a plurality of crushing blades integrally connected to the inner wall of the rotating cylinder, a first filtering cylinder integrally connected to the outer wall of the lower side of the long-axis pump body, a baffle fixedly connected to the lower side of the first filtering cylinder, a connecting plate fixedly connected to the lower side of the baffle, and a collecting device arranged on the lower side of the baffle for collecting impurities;
[0008] The collecting device comprises two collecting barrels plugged into the lower side of the connecting plate and a second filtering barrel fixedly connected to the inner wall of the collecting barrel.
[0009] Furthermore, the upper side of the rotating cylinder is engaged and slid on the lower surface of the long-axis pump body, and the first filter cylinder is sleeved on the outer side of the water suction end of the long-axis pump body.
[0010] Furthermore, the side of the cleaning brush away from the rotating cylinder is attached to the inner wall surface of the first filter cylinder, and a plurality of through holes are opened inside the connecting plate.
[0011] Furthermore, discharge holes are provided on both the left and right sides of the interior of the connecting plate, and the upper side of the collecting barrel is plugged into the inner wall surface of the discharge hole.
[0012] Furthermore, the lower side of the cleaning brush is attached to the upper surface of the connecting plate, and drainage holes are provided on opposite sides of the lower sides of the two collecting barrels.
[0013] Furthermore, the plurality of crushing blades are arranged vertically at equal intervals.
[0014] Furthermore, the two cleaning brushes are fixed on the left and right sides of the rotating cylinder in an opposing structure.
[0015] Furthermore, both left and right ends of the inner side of the connecting plate are sleeved with sealing rings that match the inner diameter of the discharge hole, and the inner wall of the sealing ring is sleeved on the outer wall surface of the upper side of the collecting device.
[0016] Compared with the prior art, the present invention provides a long-axis pump for high-temperature liquid transportation, which has the following beneficial effects:
[0017] 1. The long-axis pump for high-temperature liquid transportation crushes impurities through the crushing blade. At the same time, the cleaning brush can clean the impurities adsorbed on the surface of the first filter cylinder. When the high-temperature liquid stops flowing, it naturally falls from the discharge hole to the collection device for collection.
[0018] 2. The long-axis pump for high-temperature liquid transportation discharges the high-temperature liquid that enters at the same time into the rotating cylinder again through the drainage hole and is sucked away by the long-axis pump body. This solves the problem that after the long-axis pump crushes the impurities, the impurities still flow in the pump. After long-term use, the crushed impurities still cause blockage on the inner wall of the impurity filter frame, and it is also difficult to clean. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0024] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.
[0025] Example 1:
[0026] See also Figure 1-4In this embodiment, a long-axis pump for high-temperature liquid transportation includes a long-axis pump body 1, with a filter cleaning device 2 disposed on the lower side of the long-axis pump body 1 for filtering impurities in the liquid. The filter cleaning device 2 includes a drive motor 6 fixedly mounted on the left end of the lower side of the long-axis pump body 1, a rotating shaft 17 fixedly connected to the output end of the drive motor 6, a second gear 5 fixedly sleeved on the lower outer wall of the rotating shaft 17, a first gear 4 meshingly connected to the outer side of the second gear 5, a rotating drum 3 fixedly sleeved on the inner wall of the first gear 4, two cleaning brushes 10 integrally connected to the inner wall of the rotating drum 3, a plurality of crushing blades 9 integrally connected to the inner wall of the rotating drum 3, a first filter drum 7 integrally connected to the lower outer wall of the long-axis pump body 1, a baffle 8 fixedly connected to the lower side of the first filter drum 7, a connecting plate 11 fixedly connected to the lower side of the baffle 8, and a collection device 14 disposed on the lower side of the baffle 8 for collecting impurities. The collecting device 14 includes two collecting barrels 15 plugged into the lower side of the connecting plate 11 and a second filtering barrel 16 fixedly connected to the inner wall of the collecting barrel 15 .
[0027] Among them, the upper side of the rotating cylinder 3 is clamped and slid on the lower surface of the long-axis pump body 1, the first filter cylinder 7 is sleeved on the outside of the water suction end of the long-axis pump body 1, and the side of the cleaning brush 10 away from the rotating cylinder 3 is attached to the inner wall surface of the first filter cylinder 7. A plurality of through holes 12 are opened inside the connecting plate 11, and discharge holes 13 are opened on the left and right sides of the connecting plate 11. The upper side of the collecting barrel 15 is inserted into the inner wall surface of the discharge hole 13, and the lower side of the cleaning brush 10 is attached to the upper surface of the connecting plate 11. The opposite sides of the lower sides of the two collecting barrels 15 are provided with drainage holes 18. The two cleaning brushes 10 are fixed on the left and right sides of the rotating cylinder 3 in a relative structure.
[0028] It should be noted that the long-axis pump body 1 and the rotating cylinder 3 are both made of stainless steel, which can withstand high temperatures of high-temperature liquid flowing inside the long-axis pump body 1 under long-term use, and also has good corrosion resistance, which can extend the service life of the long-axis pump body 1 and the rotating cylinder 3.
[0029] Example 2:
[0030] See also Figure 1-2 On the basis of embodiment 1, it includes sealing rings sleeved on the left and right ends of the inner side of the connecting plate 11 and matched with the inner diameter of the discharge hole 13, and the inner wall of the sealing ring is sleeved on the outer wall surface of the upper side of the collecting device 14.
[0031] By adopting the above technical solution, it is achieved that when the collecting device 14 is inserted into the discharge hole 13 , the sealing performance can be improved through the sealing ring.
[0032] The working principle of the above embodiment is:
[0033] The high-temperature liquid is transported through the long-axis pump body 1. The impurities in the liquid will be filtered by the first filter cylinder 7. The liquid and impurities will flow upward from the through-hole 12 or edge gap in the connecting plate 11. The lower side of the discharge hole 13 is blocked by the collecting device 14, and the water flow will not affect the inside of the collecting device 14. Then, the second gear 5 is started by the driving motor 6 to engage the first gear 4 to rotate the rotating cylinder 3 to crush the impurities with the crushing blade 9, and the cleaning brush 10 cleans the crushed impurities to prevent them from clogged by adhering to the surface of the first filter cylinder 7. When the high-temperature liquid is transported, the impurities naturally fall downward from the discharge hole 13 into the collecting device 14, and the impurities falling from the through-hole 12 will continue to be isolated in the rotating cylinder 3. During this period, part of the liquid will flow into the collecting cylinder 15 with the impurities, and the impurities will be filtered into the collecting cylinder 15 through the second filter cylinder 16. The liquid that enters the collecting cylinder 15 at the same time will be discharged from the drainage hole 18, so as to collect and process the impurities. The collecting device 14 can be regularly pulled out from the discharge hole 13 and the internal impurities can be cleaned before it can be reused.
