Description

Technical Field

[0001] This utility model relates to the field of delivery pump technology, specifically to a variable frequency concentrator pump with filtration function. Background Technology

[0002] The medium-concentrating pump is an important supporting equipment for the single-effect, double-effect, and triple-effect evaporation and concentration cycle of titanium dioxide engineering. The pump has the characteristics of high efficiency and good cavitation performance, and can be widely used in chemical, petroleum, metallurgy, papermaking and other industrial sectors.

[0003] Because the conveying medium contains residue, the residue will enter the pump inlet and cause blockage when the conveying medium thickening pump is working. However, most existing conveying medium thickening pumps are equipped with filters at their inlet to filter impurities. But as the usage time increases, the residue will eventually clog the filter, requiring frequent filter replacement or cleaning, which is very inconvenient to use.

[0004] Therefore, it is of great significance to provide a variable frequency concentrator pump with filtration function to solve the problems existing in the current technology. Utility Model Content

[0005] In view of this, the purpose of this application is to provide a variable frequency concentrator pump with a filtration function to solve the problem that existing medium concentrator pumps mostly have a filter screen installed at their inlet end to filter impurities, but as the usage time increases, the residue will eventually clog the filter screen, requiring frequent filter screen replacement or cleaning, which is very inconvenient to use.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A variable frequency concentrator pump with filtration function includes a mounting base plate. A variable frequency motor is mounted on one side of the top of the mounting base plate. A pump body mounting bracket is attached to the middle of the top of the mounting base plate. A pump body is mounted on one side of the pump body mounting bracket. A filter housing is mounted on the other side of the top of the mounting base plate. A drive shaft is driven to the output end of the variable frequency motor. The output end of the drive shaft is driven to the input end of the pump body. A pump inlet pipe is mounted on one side of the pump body. A pump outlet pipe is mounted on the top of the pump body. A filter outlet pipe is mounted on the top of the filter housing. The filter outlet pipe is connected to the pump inlet pipe via a connecting pipe. A filter inlet pipe is mounted on one side of the filter housing. A filter screen is installed inside the filter housing.

[0008] Preferably, a rotating shaft is rotatably connected to the bottom end of the filter housing, a rotating frame is fixedly connected to the top end of the rotating shaft, and a scraper is installed on the side of the top end of the rotating frame, the scraper being in contact with the outer wall of the filter screen.

[0009] Preferably, a rotating rod is rotatably connected to the bottom end of the mounting base plate, a transmission sprocket is installed in the middle of the rotating rod, a drive sprocket is installed in the middle of the transmission shaft, the drive sprocket and the transmission sprocket are connected by a transmission chain, and an avoidance hole is provided in the middle of the top end of the mounting base plate, through which the transmission chain passes.

[0010] Preferably, the rotating rod is connected to a drive gear, and the bottom end of the rotating shaft is fixedly connected to a transmission gear, which meshes with the drive gear.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention uses a filter screen to filter impurities in the conveying medium. During use, the motor is started, and the motor drives the pump body through the drive shaft. The conveying medium enters the filter housing through the filter inlet pipe, and impurities are filtered through the filter screen, remaining on its outer surface. The conveying medium is then transported to the pump body inlet pipe through the connecting pipe and to the pump outlet pipe. Simultaneously, the drive shaft drives the drive sprocket to rotate, which in turn drives the transmission sprocket through the transmission chain. The transmission sprocket drives the drive gear through the rotating rod, which in turn drives the transmission gear. The transmission gear, through the rotating shaft, drives the rotating frame to rotate, which in turn drives the scraper to clean the surface of the filter screen, thus preventing clogging. Compared to existing concentrator pumps, this invention can filter impurities in the conveying medium and clean the filter screen surface simultaneously, eliminating the need for frequent cleaning and making it more convenient to use.

A scraper 21 is installed on the side of the top end of the rotating frame 20. The scraper 21 is in contact with the outer wall of the filter screen 18. The rotating frame 20 drives the scraper 21 to clean the surface of the filter screen 18, thereby preventing the surface of the filter screen 18 from being blocked by impurities.
