[0033] The following will be combined with the specific implementation of the utility model to clearly and completely describe the technical solution in the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Reduced iron powder composite polytetrafluoroethylene material is an ultrasonic piezoelectric material. The polytetrafluoroethylene (PTFE) material therein can achieve the effect of self-production of active free radicals without adding any oxidants (hydrogen peroxide, persulfate, etc.), and the water purification process does not introduce exogenous pollutants, and it has excellent chemical stability. Therefore, the reduced iron powder composite polytetrafluoroethylene material is considered as a new type of sewage treatment material; in addition, the PTFE material also has excellent piezoelectric catalytic properties, and the piezoelectric coefficient after ultrasonic activation is as high as 600pC / N. Based on this, the PTFE material can be considered as an important component of a safe and efficient water purification device for removing organic pollutants.

[0035] like Figure 1-6 As shown, the utility model is a water purification device based on reduced iron powder composite polytetrafluoroethylene material, including a mobile frame 1, a clean water tank 2, an auger roller 3, an adsorption box 4, a guide frame 5, a filter box 6, a water storage tank 7 and an ultrasonic transmitter 8, which is used to purify sewage in conjunction with the reduced iron powder composite polytetrafluoroethylene material.

[0036] The mobile frame 1 is used to carry other components, and includes a frame body and a caster set at the bottom thereof, so as to move the water purification device.

[0037] The clean water tank 2 is used for the first purification of sewage, and the clean water tank 2 is fixedly arranged on the mobile frame 1.

[0038] The auger roller 3 is used to contact the sewage in the clean water tank 2. The auger roller 3 is made of reduced iron powder and polytetrafluoroethylene material. The contact with the sewage can degrade the organic matter in the sewage. At the same time, the contact area between the auger roller 3 and the sewage is large, and the auger roller 3 is rotatably arranged in the clean water tank 2, which can disturb the sewage and improve the contact effect between the sewage and the auger roller 3, thereby helping to improve the purification efficiency of the sewage.

[0039] The adsorption box 4 is used for secondary purification of sewage. The adsorption box 4 is fixedly arranged on the mobile frame 1 and is located below the clean water tank 2. A water inlet 401 and a water outlet 402 are relatively opened on the adsorption box 4. The clean water tank 2 is provided with a drain 201, and the drain 201 is connected with the water inlet 401. After the sewage contacts the auger roller 3 in the clean water tank 2 to achieve the first purification, it flows into the adsorption box 4 along the drain 201 and the water inlet 401; the height of the bottom side of the adsorption box 4 near the water inlet 401 is greater than the height near the water outlet 402, which helps to improve the efficiency of sewage flowing from the water inlet 401 to the water outlet 402; specifically, Figure 2 As shown, the bottom side of the adsorption box 4 is stepped.

[0040] The guide frame 5 is used to guide the flow direction of the sewage in the adsorption box 4 and fix the purification material. The guide frame 5 includes a magnetic frame 51, a plurality of partitions 52 and a slide rod 53, wherein the magnetic frame 51 is fixedly arranged in the adsorption box 4, and a mounting groove 502 is provided on the top side of the magnetic frame 51. The mounting groove 502 is used to place a magnet. The reduced iron powder composite polytetrafluoroethylene material has magnetism, so that the reduced iron powder composite polytetrafluoroethylene material is adsorbed on the surface of the magnetic frame 51. A water hole 501 is provided on the magnetic frame 51, and the water inlet 401 and the water outlet 402 are connected through the water hole 501, so that the sewage entering the adsorption box 4 flows through the water hole 501 to the water outlet 402, and in the process of the sewage flowing, the sewage is allowed to contact the reduced iron powder composite polytetrafluoroethylene material on the surface of the magnetic frame 51, so as to achieve secondary purification of the sewage.

[0041] like Figure 3 As shown, a plurality of partitions 52 are alternately arranged on two side walls in the adsorption box 4 which are parallel to the direction from the water inlet 401 to the water outlet 402, so that the sewage can flow in the adsorption box 4 along an S-shaped path, thereby increasing the purification time of the sewage in the adsorption box 4; correspondingly, the length direction of the magnetic suction frame 51 is perpendicular to the length direction of the partition 52, and at least one water hole 501 is arranged between two adjacent partitions 52 and between the partition 52 and the inner wall of the adsorption box 4, and a plurality of magnetic suction frames 51 can also be arranged to absorb more reduced iron powder composite polytetrafluoroethylene material, so that the sewage in the adsorption box 4 can be fully in contact with the reduced iron powder composite polytetrafluoroethylene material, thereby improving the purification effect of the sewage.

[0042] like Figure 1 As shown, a slide groove 403 is provided on the side wall of the adsorption box 4; the magnetic frame 51 is fixedly connected to the partition 52, and the slide rod 53 is fixedly arranged on the magnetic frame 51 and / or the partition 52, and is slidably connected to the slide groove 403, so as to facilitate the removal of the guide frame 5 from the adsorption box 4, so as to realize the addition of reduced iron powder composite polytetrafluoroethylene material and the maintenance of the guide frame 5.

[0043] The filter box 6 is used to recover the reduced iron powder composite polytetrafluoroethylene material. The auger roller 3 is made of the reduced iron powder composite polytetrafluoroethylene material. During use, a small amount of powder may detach from the auger roller 3. At the same time, the reduced iron powder composite polytetrafluoroethylene material on the magnetic suction frame 51 may be impacted by the water flow and some material powder may fall off. The filter boxes 6 are fixedly arranged in the clean water tank 2 and the adsorption box 4, respectively, and correspond to the positions of the drain port 201 and the water outlet 402, respectively, and are used to filter the water entering the drain port 201 and the water outlet 402 to intercept and recover the reduced iron powder composite polytetrafluoroethylene material powder.

[0044] Specifically, the filter box 6 may be a hollow box structure, the interior of which is filled with sponge. The sponge can not only intercept and recycle the reduced iron powder composite polytetrafluoroethylene material, but also filter large particle impurities in the sewage.

[0045] The water tank 7 is used to store the purified sewage. The water tank 7 is fixedly arranged on the mobile frame 1 and is located below the adsorption box 4. The interior of the water tank 7 is connected with the water outlet 402, so that the sewage in the adsorption box 4 flows into the water tank 7 after purification. A sterilization device, such as a self-sinking ultraviolet lamp, can be installed in the water tank 7 to sterilize the water in the water tank 7.

[0046] The ultrasonic transmitter 8 is used to improve the water purification effect. The ultrasonic transmitter 8 is fixedly arranged on the bottom side of the adsorption box 4. Under the external stimulation of ultrasonic waves, the reduced iron powder composite polytetrafluoroethylene material molecules are dipole polarized to generate a built-in electric field, showing unique catalytic properties. The intermediate product after catalysis by ultrasonic piezoelectric materials is a low-concentration H2O2, which can be self-decomposed without further treatment. It is non-toxic and harmless, reduces environmental pollution, and meets the purpose of environmental protection and sustainable development. Specifically, the ultrasonic transmitter 8 is preferably an ultrasonic vibration generator.

[0047] It needs to be further explained that ultrasonic catalysis mainly utilizes the cavitation effect of ultrasound. When the ultrasound intensity is large enough, the average distance between molecules will exceed the critical value, so that the gravity between liquid molecules is destroyed and cavitation bubbles are formed. The collapse of cavitation bubbles will quickly produce "instantaneous hot spots" with a high temperature of 5000K and a high pressure of 1000atm in a small space, which will pyrolyze organic pollutants and produce H2O2, ·OH, ·HO2, and O2 at the same time, promoting redox reactions. The piezoelectric effect depends on the charge energy or separation efficiency of carriers. Tiny mechanical vibrations can generate charges on the surface of piezoelectric materials, and then generate active groups such as ·OH and ·O2- to achieve catalysis. The internal electric field formed can significantly improve the separation efficiency of photogenerated electron-hole pairs, which is beneficial to the degradation of organic pollutants. Under the external stimulation of ultrasound, the dipole polarization of piezoelectric material molecules generates a built-in electric field, showing unique catalytic properties, and synergistically promotes the degradation of organic pollutants with the cavitation effect of ultrasound.

[0048] The working principle of the water purification device based on reduced iron powder composite polytetrafluoroethylene material of the utility model is as follows:

[0049] The sewage is transported to the clean water tank 2, where it first contacts the auger roller 3 to achieve the first purification, and then flows into the adsorption box 4 through the drain port 201 and the water inlet 401, where it contacts the reduced iron powder composite polytetrafluoroethylene material adsorbed on the surface of the magnetic suction frame 51 to achieve the second purification, and then flows into the water storage tank 7 through the water outlet 402 for storage or sterilization; during this period, the filter box 6 can intercept the reduced iron powder composite polytetrafluoroethylene material powder that has fallen off to recycle it.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
