Description

Technical Field

[0001] The utility model relates to the technical field of industrial wastewater treatment, and particularly relates to a multi-stage filtration industrial wastewater purification system. Background Technique

[0002] Industrial wastewater refers to the wastewater and liquid waste generated during industrial production, which contains industrial production materials, intermediate products, by-products and pollutants generated during the production process that are lost with water. Industrial wastewater has a wide variety and complex composition. For example, electrolytic salt industrial wastewater contains mercury, heavy metal smelting industrial wastewater contains various metals such as lead and cadmium, electroplating industrial wastewater contains cyanide and various heavy metals such as chromium, petroleum refining industrial wastewater contains phenol, and pesticide manufacturing industrial wastewater contains various pesticides, etc.

[0003] At present, industrial wastewater is generally filtered by physical methods. However, when filtering industrial wastewater now, it is not convenient to treat the remaining impurities, resulting in the blockage of the subsequent filter screen and affecting the filtering effect. Especially during multi-stage filtration, it is rather troublesome to clean the impurities. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a multi-stage filtration industrial wastewater purification system, which has multiple filtration effects and can quickly remove the remaining impurities, so as to solve the problems mentioned in the background technique.

[0005] The utility model is realized by the following technical solutions: a multi-stage filtration industrial wastewater purification system, including a plurality of boxes with open upper ends, the boxes are evenly distributed from top to bottom in sequence, water outlets are arranged on the bottom surfaces of the boxes, frames are placed inside the boxes, filter nets are installed in the frames, except for the topmost box, connecting sleeves are sleeved on the upper ends of the remaining boxes, the connecting sleeves are sleeved on the adjacent boxes, the gaps between the boxes are sealed by the connecting sleeves, and slide rail mechanisms movably connected to the remaining boxes are installed at both ends of the topmost box.

[0018] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0019] All features disclosed in this specification, or all steps in the disclosed methods or processes, except for mutually exclusive features and / or steps, can be combined in any way.

[0020] Any feature disclosed in this specification (including any additional claims, abstract, and drawings), unless specifically stated, can be replaced by other equivalent or similar-purpose alternative features. That is, unless specifically stated, each feature is only an example in a series of equivalent or similar features.

[0021] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, a multi-stage filtration industrial wastewater purification system of the present utility model includes a plurality of boxes 1 with open upper ends. The boxes 1 are evenly distributed from top to bottom in sequence. Water outlets 14 are provided on the bottom surfaces of the boxes 1. Frame bodies 11 are placed inside the boxes 1, and filter meshes 12 are installed in the frame bodies 11. Except for the uppermost box 1, connecting sleeves 8 are sleeved on the upper ends of the remaining boxes 1. The connecting sleeves 8 are sleeved on the adjacent boxes 1. The gaps between the boxes 1 are hermetically arranged through the connecting sleeves 8. Slide rail mechanisms that are movably connected to the remaining boxes 1 are installed at both ends of the uppermost box 1.

[0022] In this embodiment, the slide rail mechanisms each include a plurality of positioning bars 6, a plurality of fixing blocks 3, and L-shaped plates 5. The plurality of fixing blocks 3 are installed on the end faces in the width direction of the box 1. Positioning grooves 4 are provided on the outer side surfaces of the fixing blocks 3. The positioning bars 6 are slidably arranged in the positioning grooves 4. The widths of the upper fixing blocks 3 are greater than the widths of the lower fixing blocks 3. One end of each L-shaped plate 5 is installed on the positioning bar 6, and the other end extends to the outside of different boxes 1 and is respectively installed with a fixing frame 10. The fixing frames 10 are installed outside the boxes 1. A plurality of compression springs 9 are installed between the fixing frames 10 and the connecting sleeves 8. The L-shaped plates 5 are arranged one inside and one outside.

[0023] In this embodiment, the cross-sections of the positioning bars 6 and the positioning grooves 4 are both trapezoidal structures. Limit blocks 7 are installed at one end of each positioning bar 6, which limits the moving distance of the positioning bar 6 and avoids the positioning bar 6 moving excessively and disengaging from the positioning groove.

[0024] In this embodiment, a sealing ring of a frame structure is embedded on the inner side surface of the connecting sleeve 8. The inner side surface of the sealing ring is flush with the inner side surface of the connecting sleeve 8, and the inner side surfaces of the sealing ring are also in contact with the outer wall surface of the box body 1. The sealing ring increases the sealing between the connecting sleeve and the box body, thereby preventing internal sewage from flowing out from the gap between the connecting sleeve and the box body.

[0025] In this embodiment, hand-held handles 13 are installed at both ends of the frame 11 .

[0026] In this embodiment, a plurality of connecting seats 2 are installed on one side surface of the top box body 1, and a plurality of fixing holes are provided on the connecting seats 2. Bolts can pass through the fixing holes to fix the device under the sewage pipe and connect the lower end of the sewage pipe to the top box body.

[0027] Industrial wastewater can enter from the top box, and pass through each box from top to bottom, and be filtered by multiple filter screens, among which the types of filter screens are different, from top to bottom, they can be coarse filter screens, activated carbon filter screens, iron and manganese removal filter screens, etc., to ensure the filtering effect;

[0028] Among them, impurities generated by filtration can be directly collected by the box body. When the impurities need to be cleaned, the connecting sleeve can be moved downward to make the upper part of the connecting sleeve detach from the adjacent box body. At this time, the box body can be pulled outward along the positioning groove to make the L-shaped plate on the box body move outward along the positioning groove until the box body is staggered with the adjacent box body, so that the upper end opening of the box body is in an open state. The staff's hand can directly reach into the interior of the box body and grasp the hand-held handle to directly pop out the frame body and the filter net, and simultaneously take out the impurities inside, which is convenient for cleaning. After the box body returns to its original position, the connecting sleeve can be released, and the connecting sleeve can be again put on the adjacent box body through the rebound of the compression spring, so that the boxes can be directly connected and sealed.

[0029] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
