[0029] Example 1

[0030] An industrial wastewater treatment pump head, such as Figures 1 - 3As shown, it includes a water pump head body 100 and a mounting base 200. The bottom of the water pump head body 100 is connected to the mounting base 200, and the water pump head body 100 is communicated with the mounting base 200. It also includes a pollutant blocking mechanism 5, and the pollutant blocking mechanism 5 includes a fixed mounting ring 501, a swing support rod 502 and a first filter screen 504. The water pump head body 100 is bolted with a fixed mounting ring 501, and the fixed mounting ring 501 is rotatably connected with the swing support rod 502 at intervals. After the swing support rod 502 contacts the bottom of the industrial sewage pool, under the action of gravity, the water pump head body 100 will move downward, squeezing the swing support rod 502 to rotate, so that the swing support rod 502 opens, and a first filter screen for filtering pollutants is connected between the swing support rods 502. 504. The first filter screen 504 is elastic and can be opened or contracted according to the swing of the swing support rod 502. The swing support rod 502 can be opened to expand the first filter screen 504. After the first filter screen 504 is expanded, it can filter industrial wastewater over a large area to ensure pumping efficiency. Moreover, even if a certain position on the first filter screen 504 is blocked, it will not affect the filtering effect of the first filter screen 504, thereby ensuring the pumping efficiency of the water pump head body 100. It also includes a first volute spring 503. The first volute spring 503 is connected to the swing support rod 502 and the fixed mounting ring 501 to enable the swing support rod 502 to rotate and elastically reset. When the water pump head body 100 is lifted up, the first volute spring 503 can drive the swing support rod 502 to reverse and reset, so that the first filter screen 504 shrinks and resets.

[0031] When the industrial wastewater treatment pump head needs to be used, the industrial wastewater treatment pump head is first installed in the designated position, and then the industrial wastewater treatment pump head is placed in the industrial wastewater pool so that the swing support rod 502 contacts the bottom of the industrial wastewater pool. Under the action of gravity, the water pump head body 100 will move downward, squeezing the swing support rod 502 to rotate and spread apart from each other, the first volute spring 503 is deformed, and the swing support rod 502 can spread open the first filter screen 504. At this time, industrial wastewater is extracted through the water pump head body 100, and the first filter screen 504 is opened. A filter 504 can filter industrial wastewater, separate the pollutants in the industrial wastewater, and prevent the pollutants from clogging the pump head body 100. The contact area between the first filter 504 and the industrial wastewater is large. Even if a certain place on the first filter 504 is blocked, it will not affect the filtering effect of the first filter 504, thereby improving the pumping efficiency. After the pumping is completed, the industrial production wastewater treatment pump head is taken out. At this time, the first volute spring 503 returns to its original state, driving the swing support rod 502 to rotate and close to each other, so that the first filter 504 shrinks and resets.

[0032] likeFigure 2 and Figure 4 As shown in Figure 4 , it further includes a clogging prevention mechanism 6. The clogging prevention mechanism 6 includes a pollutant filter plate 601 and a scraping component. The inner top of the installation and fixing seat 200 is connected with the pollutant filter plate 601. The pollutant filter plate 601 blocks the bottom of the water pump head body 100. When the water pump head body 100 pumps industrial sewage, the pollutant filter plate 601 can filter the industrial sewage, thereby preventing the water pump head body 100 from being blocked and ensuring the pumping efficiency of the water pump head body 100. The installation and fixing seat 200 is provided with a scraping component for scraping the pollutants on the pollutant filter plate 601. The scraping component includes a pollutant scraping rod 602 and a hydraulic rotating paddle 603. A guiding sliding groove 604 is formed on the installation and fixing seat 200. The pollutant scraping rod 602 is rotatably connected to the guiding sliding groove 604. The pollutant scraping rod 602 contacts the pollutant filter plate 601. When the water pump head body 100 pumps industrial sewage, the industrial sewage can drive the pollutant scraping rod 602 to rotate. The rotation of the pollutant scraping rod 602 can scrape the pollutants adhering to the pollutant filter plate 601, thereby preventing the pollutant filter plate 601 from being blocked. The middle of the pollutant filter plate 601 is rotatably connected with the hydraulic rotating paddle 603. The hydraulic rotating paddle 603 is fixedly connected with the pollutant scraping rod 602. The blades of the hydraulic rotating paddle 603 are all inclined and have the same inclination angle. When the water pump head body 100 pumps industrial sewage, the pollutant filter plate 601 can filter the industrial sewage twice to prevent the pollutants from blocking the water pump head body 100. At the same time, the flow of the industrial sewage can drive the hydraulic rotating paddle 603 to rotate. The hydraulic rotating paddle 603 drives the pollutant scraping rod 602 to rotate. The pollutant scraping rod 602 can scrape the pollutants adhering to the pollutant filter plate 601, preventing the pollutant filter plate 601 from being blocked and ensuring the pumping efficiency.

[0033] Such as Figure 2 、 Figure 4 、 Figure 5 and Figure 6As shown, it also includes a pollutant collection mechanism 7, which includes a pollutant collection box 701 and a toggle assembly. The pollutant collection box 701 is connected to the mounting base 200 at intervals. The pollutant collection box 701 can collect pollutants in industrial wastewater. The pollutant scraper 602 is provided with a toggle assembly for toggling the pollutants into the pollutant collection box 701. The toggle assembly includes a pollutant toggle piece 702 and a second volute spring 703. The pollutant scraper 602 is rotatably connected to two pollutant toggle pieces 702. The two pollutants The paddle plate 702 is symmetrically arranged. When the pollutant scraper rod 602 rotates, it can drive the pollutant paddle plate 702 to rotate. The pollutant paddle plate 702 rotates and contacts the pollutant collection box 701, thereby being able to paddle the pollutants into the pollutant collection box 701. The second volute spring 703 connects the pollutant paddle plate 702 and the pollutant scraper rod 602 to enable the pollutant paddle plate 702 to rotate and elastically reset. When the pollutant paddle plate 702 rotates and separates from the pollutant collection box 701, the second volute spring 703 can drive the pollutant paddle plate 702 to rotate in the opposite direction and reset.

[0034] When the pollutant scraper 602 rotates, it will drive the pollutant paddle plate 702 to rotate. The pollutant paddle plate 702 can paddle the pollutants in the industrial wastewater into the pollutant collection box 701. When the pollutant paddle plate 702 contacts the pollutant collection box 701, the pollutant collection box 701 will squeeze the pollutant paddle plate 702 to rotate, and the second volute spring 703 will be deformed. The pollutant collection box 701 can scrape off the pollutants stuck on the pollutant paddle plate 702, causing the pollutants to fall into the pollutant collection box 701. When the pollutant paddle plate 702 is separated from the pollutant collection box 701, the second volute spring 703 returns to its original state, driving the pollutant paddle plate 702 to rotate and reset. Subsequently, the pollutants in the pollutant collection box 701 can be collected and processed manually.

[0035] like Figure 4 and Figure 7 As shown, a filtering mechanism 8 is also included, and the filtering mechanism 8 includes a mounting ring 801 and a second filter screen 802. A mounting ring 801 is installed at the bottom of the water pump head body 100, and a second filter screen 802 for filtering industrial wastewater is connected to the mounting ring 801. The second filter screen 802 can filter the industrial wastewater entering the water pump head body 100, thereby completing the third filtration of the industrial wastewater and preventing pollutants from clogging the water pump head body 100.
