Technical Field

[0001] The utility model relates to the field of water treatment and degradation equipment, in particular to a photocatalytic degradation device for water treatment. Background Art

[0002] Photocatalytic degradation is an effective way to solve the problem of organic pollution in water bodies because it can directly use sunlight, save energy and reduce consumption, and will not cause secondary water pollution problems. Photocatalytic degradation uses light energy to stimulate the active sites on the surface of the catalyst, enabling it to undergo redox reactions with harmful substances and decompose them into harmless substances, such as water and carbon dioxide.

[0003] At present, a film with chemicals is usually placed on the reaction device. The water to be degraded passes through the reaction film, and the chemical reacts with the water under the irradiation of artificial light or sunlight to achieve degradation. However, after long-term use, the reaction film will be washed away, bubbled, or even damaged, especially at the edges, which are more easily washed away.

[0004] The application number is 201510497872.8, which discloses a photocatalytic treatment method and device for efficiently removing organic pollutants from water bodies. It discloses that the sewage in the sewage storage circulation pool at the lower level is pumped to the water storage groove at the top level by a centrifugal pump. Since the outer edge of the groove is high and the inner edge is low, when the water level reaches the height of the inner edge, the sewage will slowly overflow and flow through the glass substrate coated with a PW11Fe / TiO2 composite film at a certain rate under the action of gravity. This solution realizes a relatively efficient photocatalytic degradation reaction, but the problem of bubbles in the above-mentioned glass film during long-term use still exists.

DETAILED DESCRIPTION

[0025] In order to make it easier to understand the structure of the present invention and the functional features and advantages that can be achieved, the preferred embodiments of the present invention are described in detail with reference to the drawings as follows:

[0026] Example:

[0027] like Figures 1 to 3As shown, the utility model provides a photocatalytic degradation device for water treatment, including a water storage tank and a reaction bucket 2, the top of the water storage tank 1 is fixedly connected to the bottom wall of the reaction bucket 2, and further includes a connecting pipe, a water pump, a groove and a perforation, the groove is located on the inner side of the reaction bucket 2, the edge of the groove is lower than the edge of the reaction bucket 2, and the reaction bucket 2 and the groove are integrally formed by 3D printing, the perforation is opened at the corner of the groove, and the connecting pipe is connected, and the two ends of the connecting pipe are connected to the water pump. When working, turn on the water pump to transport the water in the water storage tank 1 to the groove through the connecting pipe. Since the edge of the groove is lower than the edge of the reaction bucket 2, the water flow will flow through the inner wall of the reaction bucket 2 after filling the groove, so as to pass through the reaction film, and improve the reaction efficiency of the reactant and water on the reaction film through sunlight irradiation, and the water after the reaction flows into the water storage tank 1, so as to realize the degradation of sewage in a reciprocating manner.

[0028] As another example, Figures 4 to 6 As shown, the present application also includes a hot air pen 3 for heating, so that the reaction film is closely attached to the inner wall of the reaction bucket 2. The edge of the reaction bucket 2 is movably provided with a moving mechanism 5 for moving the hot air pen 3. The moving mechanism 5 includes a telescopic plate 51, a roller 52, a rotating shaft 53, a threaded rod 54, a threaded sleeve 55, and a spring 56. The telescopic plate 51 is clamped on both sides of the edge of the reaction bucket 2, the rotating shaft 53 is fixed to the inner wall of the telescopic plate 51, the roller 52 is rotatably connected to the rotating shaft 53, and a plurality of rollers 52 are symmetrically arranged on both sides of the edge of the reaction bucket 2. The threaded rod 54 passes through the telescopic plate 51 and is threadedly connected to the telescopic plate 51. The threaded sleeve 55 is rotatably sleeved on one end of the threaded rod 54, and the spring 56 is fixedly connected to the telescopic plate 51, so that the telescopic plate 51 can be elastically extended. The outer surface of the roller 52 is fixedly attached with a first rubber pad 521.

[0029] The roller 52 in the telescopic plate 51 is clamped at the edge of the reaction bucket 2. The rollers 52 are symmetrically arranged on both sides, and there are at least two rollers 52 on each side. The spring 56 enables the telescopic plate 51 to achieve elastic expansion and contraction. The spring 56 gives the telescopic plate 51 a certain pulling force, so that the roller 52 can be close to the edge of the reaction bucket 2. When passing through the corner of the reaction bucket 2, the telescopic plate 51 is stretched open by the corner of the reaction bucket 2, and the roller 52 presses the edge. Further optimization, the rotating shaft 53 is set as an elastic telescopic structure in the direction of squeezing the edge of the reaction bucket 2. When the rollers 52 pass through the corner of the edge of the reaction bucket 2, each roller 52 can fit the edge of the reaction bucket 2, thereby improving stability. The first rubber pad 521 can increase the friction between the roller 52 and the edge of the reaction bucket 2 on the one hand, and can protect the edge of the reaction bucket 2 on the other hand. When the roller 52 moves to a suitable position, the threaded sleeve 55 is screwed to squeeze the telescopic plate 51 tightly, so that the telescopic plate 51 and the roller 52 are stably clamped at the edge of the reaction bucket 2.

[0030] As another example, Figure 3 and Figure 7As shown, the side of the mobile mechanism 5 of the present application away from the reaction bucket 2 is fixedly connected with a through slot 41. The telescopic plate 51 is fixedly connected with a support rod 6 at the top of the outer layer, and one end of the support rod 6 away from the telescopic plate 51 is fixedly connected to the end of the through slot 41. The through slot 41 supported by the support rod 6 can move with the movement of the roller 52, and the support rod 6 can also serve as a handle. After loosening the threaded cap, the support rod 6 can be grasped and pushed or pulled to move on the edge of the reaction bucket 2.

[0031] As another example, Figure 7 and Figure 8 As shown, the clamping mechanism 7 for making the hot air pen 3 perpendicular to the inner wall of the reaction bucket 2 is slidably connected in the through slot 41 of the present application. The clamping mechanism 7 includes a slider 71, a clamping plate 72, a slot 73, a connecting block 74 and an elastic telescopic rod 75. The slider 71 is slidably connected to the through slot 41. In addition to fitting the through slot 41, the slider 71 is required to be extended due to the need to connect the clamping plate 72 and other components. The slot 73 is provided on one side of the slider 71, and the clamping plate 72 slides in the slot 73 through the connecting block 74. The two ends of the elastic telescopic rod 75 are respectively fixedly connected to the inner wall of the connecting block 74 and the slot 73, so that the connecting block 74 slides elastically in the slot 73, and the hot air pen 3 is clamped by the clamping plate 72. There are two splints 72, two corresponding slots 73, and two corresponding connecting blocks 74. After the two splints 72 are opened, the hot air pen 3 is placed between the two splints 72, and the splints 72 are loosened. The splints 72 clamp the hot air pen 3 by the elasticity of the elastic telescopic rod 75. The splint 72 is arc-shaped, and the second rubber pad 721 is fixedly connected to the side of the splint 72 where the arc is folded. Since the hot air pen 3 is mostly a column, the splint 72 is an arc-shaped plate to better clamp the hot air pen 3. The second rubber pad 721 can reduce the rigid clamping of the splint 72 on the hot air pen 3 and protect the hot air pen 3.

[0032] As another example, Figure 1 , Figure 4 and Figure 7 As shown, the through groove 41 of the present application is parallel to the inner wall of the reaction bucket 2, and the slider 71 is perpendicular to the through groove 41 and the inner wall of the reaction bucket 2. The through groove 41 is provided with a through groove on the side away from the reaction bucket 2, and baffles 42 are fixedly connected at both ends of the through groove 41. Since the hot air pen 3 usually needs to be connected to the conveying pipe, a through groove is provided on the through groove 41 to facilitate the movement of the conveying pipe on the through groove 41. The baffles 42 at both ends of the through groove 41 prevent the slider 71 from sliding out. The inner wall of the reaction bucket 2 is an inclined square funnel. When the through groove 41 is parallel to the inner wall of the reaction bucket 2, and the slider 71 is perpendicular to the inner wall of the reaction bucket 2, the hot air pen 3 is always perpendicular to the inner wall of the reaction bucket 2. Heating the bubbling part of the reaction film at a vertical angle is more efficient than at an inclined angle and reduces the probability of damage to the reaction film when the hot air pen 3 blows.

[0033] As another example, Fig. 9 As shown, in order to improve the heating stability of the hot air pen 3 and reduce the probability of damage to the reaction film caused by concentrated wind force of the hot air pen 3, the present application provides an air dispersion hood at the pen end of the hot air pen 3, and the air dispersion hood is screwed on the end of the hot air pen 3 by threads or is attracted to the end of the hot air pen 3 by magnetic attraction, and the air dispersion hood is connected to the hot air pen 3 through an inner cover, and air leakage holes are provided on the side walls of the inner cover, and the side walls of the outer cover are closed, but air leakage holes are provided on the bottom wall of the outer cover, so that the wind direction is dispersed through the inner cover, thereby reducing the concentration of wind force, improving the heating stability and protecting the reaction film.

[0034] The working principle of a photocatalytic degradation device for water treatment in the present application is as follows: when the reaction film generates bubbles or the edge is flushed, loosen the threaded cap, push the support rod 6, and the telescopic plate 51 moves along the edge of the reaction bucket 2. When it reaches the position that needs to be repaired, loosen the support rod 6, tighten the threaded cap, and fix the telescopic plate 51. Open the clamp 72 and place the hot air pen 3 between the clamps 72, turn on the switch of the hot air pen 3, cover the end of the hot air pen 3 with a wind hood, grasp the slider 71, and make the slider 71 and the hot air pen 3 slide in the through groove 41. Since the through groove 41 is parallel to the inner wall of the reaction bucket 2, the hot air pen 3 is always perpendicular to the inner wall of the reaction bucket 2. When the hot air pen 3 is slid to the bubbling place, slightly slide the slider 71 to heat the bubbling place evenly. After the repair is completed, turn off the switch of the hot air pen 3. In addition to being able to repair small pieces, it can also be heated during lamination to make the reaction film fit the reaction bucket 2 more closely.

Any technician familiar with the field can make many possible changes and modifications to the technical solution of the present invention by using the above technical content without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes. Therefore, any changes, modifications, equivalent changes and modifications made to the above embodiments based on the technology of the present invention without departing from the content of the technical solution of the present invention belong to the protection scope of the present technical solution.
