Abstract
Description
Technical Field
[0001] This utility model relates to the field of centrifugal pumps, and in particular to a high-efficiency and energy-saving vertical split-case centrifugal pump. Background Technology
[0002] A centrifugal pump is a type of impeller pump that uses the centrifugal force generated by the rotation of an impeller to transport liquids. During rotation, the impeller blades interact with the liquid, transferring mechanical energy to the liquid and increasing its pressure, thus achieving the purpose of liquid transport. Centrifugal pumps come in various types, including vertical, horizontal, single-stage, multi-stage, single-suction, double-suction, and self-priming pumps. They are widely used in industries such as industrial and urban water supply and drainage, energy, metallurgy, chemical, textile, papermaking, petroleum, power, food and pharmaceutical, and synthetic fiber manufacturing.
[0003] When existing centrifugal pumps are used to pump liquids with a lot of impurities, the filtration capacity of the internal anti-clogging structure of the pump body is limited. Therefore, after a period of use, the pump body needs to be shut down and cleaned by the staff, which affects the work progress.
[0004] Therefore, it is necessary to provide a new, high-efficiency, and energy-saving vertical split-case centrifugal pump to solve the above-mentioned technical problems. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a high-efficiency and energy-saving vertical split-case centrifugal pump, which solves the problem that the existing centrifugal pump's internal anti-clogging structure has limited filtration capacity and requires staff to stop the pump for cleaning after a period of use, thus affecting the work progress.
[0006] The high-efficiency and energy-saving vertical split-case centrifugal pump provided by this utility model includes a pump body, an inlet pipe on the pump body, a filter box on one side of the pump body, a drain pipe connected to one end of the filter box, and an inlet pipe connected to the other end of the filter box.
[0007] The filter box has a fixed partition seat inside, and several filter screens are arranged at intervals on both sides of the partition seat. The filter screens are installed inside the filter box.
[0008] In a preferred embodiment, the drain pipe and the inlet pipe are connected by a flange.
[0009] In a preferred embodiment, two rotating columns are movably arranged inside the filter box, and a sealing plate is fixed on one side of each of the two rotating columns.
[0010] Both sides of the filter box are detachably mounted with side plates via bolts.
[0011] In a preferred embodiment, two rotating shafts are spaced apart on one side of the filter box. One end of each rotating shaft extends into the filter box and is fixedly connected to the rotating column, while a worm gear is installed at the other end of the rotating shaft.
[0012] A limiting seat is fixed on one side of the filter box, and a drive shaft is movably mounted on the limiting seat. Both ends of the drive shaft are connected to worm gears, and the two worm gears mesh with the two worm wheels respectively.
[0013] In a preferred embodiment, a movable mounting shaft is provided on one side of the filter box, and a first bevel gear is mounted on the mounting shaft.
[0014] One of the worm gears is equipped with a second bevel gear, which meshes with the first bevel gear.
[0015] In a preferred embodiment, a crank is mounted on the mounting shaft.
[0016] The beneficial effects of this utility model are:
[0017] When in use, this device can fully filter the water entering the pump body through several filter screens, greatly reducing the load on the anti-clogging structure inside the pump body. By setting up a partition seat and two sealing plates, the entire filter box can be divided into two treatment chambers. When the filter screen of one chamber needs to be cleaned, the operator can turn the crank to make the two worm gears rotate in opposite directions until water can flow through the other chamber and it can be used normally. Then, the corresponding side plate can be opened to clean the chamber to be treated. The water pump does not need to be turned off during the cleaning process, so it does not affect normal use and saves energy. Attached Figure Description

Detailed Implementation
[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0024] Please refer to the following: Figure 1 , Figure 2 , Figure 3 as well as Figure 4 ,in Figure 1 A three-dimensional view of the main structure of the high-efficiency and energy-saving vertical split-case centrifugal pump provided by this utility model; Figure 2 for Figure 1 A magnified structural diagram of A is shown below; Figure 3 A plan view of the main structure of the high-efficiency and energy-saving vertical split-case centrifugal pump provided by this utility model; Figure 4 This is an internal structural view of the filter box provided by this utility model.
[0025] In the specific implementation process, such as Figures 1-4 As shown, the system includes a pump body 1, an inlet pipe 2, and a filter box 3 on one side of the pump body 1. One end of the filter box 3 is connected to a drain pipe 4, which is connected to the inlet pipe 2 via a flange 8. The other end of the filter box 3 is connected to an inlet pipe 5. A partition seat 6 is fixed inside the filter box 3, and several filter screens 7 are spaced apart on both sides of the partition seat 6. The filter screens 7 are installed inside the filter box 3. Two rotating columns 9 are movably arranged inside the filter box 3, and a sealing plate 10 is fixed on one side of each of the two rotating columns 9. The rotating columns 9 and the partition seat 6 are sealed, for example, by placing a wear-resistant rubber gasket at the contact point between the rotating columns 9 and the partition seat 6, and a wear-resistant rubber gasket at the contact point between the sealing plate 10 and the filter box 3. Side plates 11 are detachably installed on both sides of the filter box 3 by bolts. The chamber to be treated can be cleaned by opening the corresponding side plates 11.
[0026] Two rotating shafts 12 are spaced apart on one side of the filter box 3. One end of the rotating shaft 12 extends into the interior of the filter box 3 and is fixedly connected to the rotating column 9. A worm gear 13 is installed on the other end of the rotating shaft 12. A limit seat 14 is fixed on one side of the filter box 3. A transmission shaft 15 is movably mounted on the limit seat 14. Worms 16 are connected to both ends of the transmission shaft 15. The two worms 16 mesh with the two worm gears 13 respectively. A movable mounting shaft 17 is mounted on one side of the filter box 3. A first bevel gear 18 is mounted on the mounting shaft 17. A second bevel gear 19 is mounted on one of the worms 16. The second bevel gear 19 meshes with the first bevel gear 18. A hand crank 20 is mounted on the mounting shaft 17. The operator can turn the hand crank 20 to drive the mounting shaft 17 to rotate. Under the transmission action of the first bevel gear 18 and the second bevel gear 19, the two worms 16 will drive the two worm gears 12 to rotate in opposite directions.
[0027] The working principle of this utility model is as follows: When this device is in use, the water flowing into the pump body 1 can be fully filtered through several filter screens 7, which greatly reduces the load on the anti-clogging structure inside the pump body 1. By setting the partition seat 6 and two sealing plates 10, the entire filter box 3 can be divided into two processing chambers. When the filter screen 7 of one of the chambers needs to be cleaned, the operator can turn the crank 20 to drive the mounting shaft 17 to rotate. Under the transmission action of the first bevel gear 18 and the second bevel gear 19, the two worm gears 16 will drive the two worm wheels 12 to rotate in opposite directions until water can flow into the other chamber and it can be used normally. Then, the corresponding side plate 11 can be opened to clean the chamber to be processed. The water pump does not need to be turned off during the cleaning process, which does not affect normal use and saves energy.
[0028] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
