Description

Technical Field

[0001] This utility model belongs to the field of chemical production technology, and in particular relates to an improved phosphorus removal agent production and impurity removal device. Background Technology

[0002] Phosphorus removal agents are used for coagulation and turbidity removal treatment of urban water sources, achieving deep phosphorus removal while simultaneously treating urban water sources. Currently, in the production of phosphorus removal agents, a purification device is usually required to filter the precipitates and impurities generated after the reaction. Existing purification devices for phosphorus removal agent production typically include a tank with a fixed frame installed on the outside, a support column installed at the bottom of the frame, a discharge pipe installed at the top of the tank, a feed pipe installed at the bottom of one side of the tank, a conical bottom of the tank, a drain pipe installed at the bottom of the tank, and a filter screen installed inside the tank. The tank also has a cleaning mechanism, which includes a rotating shaft whose bottom end passes through the bottom end of the filter screen, and the shaft and filter screen are rotatably connected. This type of purification device can only clean the bottom of the filter screen during use. However, when precipitates or impurities accumulate on the top of the filter screen, they cover the screen, affecting the filtration and separation efficiency. Utility Model Content

Figure 1 and attached Figure 2 As shown, an improved phosphorus removal agent production and impurity removal device includes an impurity removal tank 1. An annular protrusion 11 is integrally provided on the lower middle side of the interior of the impurity removal tank 1. A filter screen 5 is detachably and fixedly installed on the upper part of the annular protrusion 11. A central connecting pipe 51 is integrally provided in the middle of the filter screen 5. A cleaning cover 12 is detachably and fixedly installed at the right opening of the impurity removal tank 1.

A discharge valve 4 is fixedly installed at the lower discharge port of the impurity removal tank 1. A sediment electric scraper assembly 6 is installed in the impurity removal tank 1.

[0017] In this implementation plan, in conjunction with the appendix Figure 3As shown, the sediment electric scraper assembly 6 includes a motor 61, and a rotating shaft 62 is fixedly installed at the lower end of the motor 61. From top to bottom, an upper scraper 63, a lower scraper 64, and a toggle rod 66 are detachably and fixedly installed at the lower end of the rotating shaft 62. The upper scraper 63, the lower scraper 64, and the toggle rod 66 are all composed of a stainless steel ring set in the middle and stainless steel rods integrated at both ends of the stainless steel ring. The stainless steel ring is used to connect with the rotating shaft 62.

[0018] In this embodiment, specifically, the shape of the stainless steel rod of the upper scraper 63 and the shape of the stainless steel rod of the lower scraper 64 are adapted to the central connecting pipe 51.

[0019] In this embodiment, specifically, a brush layer 65 is fixedly installed on the lower part of the upper scraper 63. The brush layer 65 is set on the upper part of the filter screen 5. When the upper scraper 63 rotates, it moves the sediment on the upper side of the filter screen 5, reducing the coverage area of ​​the sediment or impurities on the filter screen 5 and improving the filtration and separation efficiency.

[0020] In this embodiment, specifically, a brush layer 65 is fixedly installed on the upper part of the lower scraper 64. The brush layer 65 is located at the lower part of the filter screen 5. When the lower scraper 64 rotates, it can scrape and clean the lower part of the filter screen 5.

[0023] Working principle

[0024] In this invention, the material requiring impurity removal during the production of the dephosphorizing agent is fed into the impurity removal tank 1 through the feed pipe 2 and the feed valve 3. The electric scraper assembly 6 moves the material, allowing it to pass through the filter screen 5 for impurity removal. After filtration, the cleaning cover 12 is opened to facilitate the removal of impurities accumulated on the top of the filter screen 5 by production personnel. When the motor 61 rotates, it drives the upper scraper 63, the lower scraper 64, and the agitator 66 to rotate. The rotation of the upper scraper 63 can move the sediment on the upper side of the filter screen 5, reducing the coverage area of ​​the sediment or impurities on the filter screen 5.
