Description

Technical Field

[0001] This application relates to the technical field of wastewater filtration, and particularly to an industrial wastewater pretreatment device. Background Art

[0002] Industrial production activities cover a wide range, and various types of wastewater with complex components will be generated during the production process. Chemical production often involves numerous chemical reactions. In the reactions, raw materials may not react completely or new insoluble substances may be formed. These substances will exist in the wastewater in the form of floating objects or large impurities. For example, heavy metal ions may combine with certain substances to form precipitate blocks, and unreacted organic substances may also float on the water surface. In the printing and dyeing industry, in processes such as dyeing and printing, dyes, auxiliaries, and sizing agents used are partially unable to dissolve completely or disperse evenly. Dyes agglomerate into blocks, and auxiliaries remain floating, resulting in a large amount of floating objects and large impurities mixing into the printing and dyeing wastewater. In the paper industry, lignin and cellulose in the raw materials will partially exist in large block forms due to improper treatment during the processing. At the same time, printing materials such as ink will also enter the wastewater during paper production and subsequent processing, becoming floating or block impurities. If directly discharged, it will inevitably cause serious pollution to the environment.

[0003] Before purifying industrial wastewater, it is necessary to remove floating impurities or large impurities in the wastewater. Traditional industrial wastewater pretreatment usually adopts the method of intercepting with a filter screen, blocking floating objects and large impurities on one side of the filter screen, so as to complete the pretreatment of industrial wastewater. However, after the impurities accumulate on one side of the filter screen, the filter screen will be blocked, and then relevant operators need to clean the blocked filter screen. This manual cleaning method is time-consuming and laborious, affecting the pretreatment efficiency of industrial wastewater. Summary of the Invention

Detailed implementation manners

[0025] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present application, and should not be construed as limiting the present application.

[0026] The industrial wastewater pretreatment device of the embodiments of the present application will be described below with reference to the accompanying drawings.

[0027] As Figures 1 - 6 shown, the industrial wastewater pretreatment device of the embodiments of the present application may include a sewage discharge pipe 1, a filter box 2, an impurity removal assembly 3, an aggregate box 4, and a discharge pipe 5.

[0028] Among them, the sewage discharge pipe 1 is arranged on one side of the filter box 2.

[0029] It should be noted that the sewage discharge pipe 1 described in this example is the pipe for discharging industrial wastewater, and the industrial wastewater is discharged into the impurity removal assembly 3 through the sewage discharge pipe 1.

[0030] A filter plate 20 is arranged inside the filter box 2.

[0031] It should be noted that in this embodiment, a plurality of water leakage holes are formed in the filter plate 20. Through the arrangement of the plurality of water leakage holes, wastewater can leak out, and floating impurities and large-volume impurities are retained on the filter plate 20, thereby realizing the separation of impurities and wastewater.

[0032] The impurity removal component 3 is arranged on the filter tank 2, and one end of the impurity removal component 3 is slidably connected to the filter plate 20.

[0033] It should be noted that the impurity removal component 3 described in this embodiment is used to rotate and clean the impurities retained in the filter tank 2 and clean the impurities into the aggregate tank 4, so that manual impurity removal is not required, and the pretreatment efficiency of industrial wastewater is greatly improved.

[0034] The aggregate tank 4 is arranged on one side of the filter tank 2.

[0035] It can be understood that through the arrangement of the aggregate tank 4, impurities can be collected in the aggregate tank 4, thus facilitating the cleaning of impurities.

[0036] One end of the discharge pipe 5 is communicated with the bottom of the filter tank 2.

[0037] It can be understood that through the connection between the discharge pipe 5 and the bottom of the filter tank 2, the industrial wastewater is discharged from the discharge pipe 5 after filtration and discharged from the discharge pipe 5 into a sedimentation tank (not shown in the figure) for purification treatment.

[0038] Specifically, in the actual operation process, industrial wastewater flows from the sewage discharge pipe 1 into the filter tank 2. The filter plate 20 filters the industrial wastewater, leaving the impurities on the filter plate 20, allowing the sewage to flow from the filter tank 2 into the discharge pipe 5 and then from the discharge pipe 5 into the sedimentation tank for purification treatment.

[0039] The impurity removal component 3 does work and rotates in the filter tank 2. When the impurity removal component 3 rotates, it is slidably connected to the filter plate 20, rotates the impurities from the inside of the filter tank 2 to the outside of the filter tank 2, and discharges them into the aggregate tank 4, thereby completing the pretreatment of the impurities and eliminating the need for manual cleaning by relevant operators, improving the pretreatment efficiency of industrial wastewater.

[0040] In an embodiment of the present application, as Figure 1 shown, for the industrial wastewater pretreatment device according to the claims, it is characterized in that the filter plate 20 is arc-shaped.

[0041] It can be understood that through the arc-shaped design of the filter plate 20, it is convenient for the impurity removal component 3 to rotate and clean the impurities on the filter plate 20, thereby ensuring the impurity removal effect of the impurity removal component 3.

[0042] In an embodiment of the present application, as Figure 1 and Figure 3As shown, the impurity removal component 3 may include a motor 30, a rotating drum 31, and a plurality of impurity removal plates 32.

[0043] Among them, the motor 30 is arranged on the filtration tank 2, the rotating drum 31 is rotatably arranged in the filtration tank 2, a plurality of impurity removal plates 32 are respectively arranged on the rotating drum 31, and one ends of the plurality of impurity removal plates 32 are respectively slidably connected to the filter plate 20.

[0044] It can be understood that the rotation of the motor 30 driving the rotating drum 31 can drive the rotation of the plurality of impurity removal plates 32. The rotation of the plurality of impurity removal plates 32 can rotate the impurities in the filtration tank 2 onto the impurity removal plates 32 and transfer the impurities into the aggregate tank 4. In addition, the way the impurities are transferred into the aggregate tank 4 includes gravity settlement or other methods, which are specifically set according to the actual situation.

[0045] In an embodiment of the present application, as Figure 3 shown, a plurality of filter holes 320 are formed in the impurity removal plate 32.

[0046] It can be understood that through the arrangement of the filter holes 320, when the impurity removal plate 32 rotates, industrial wastewater can leak out from the filter holes 320, thereby reducing the rotation resistance of the impurity removal plate 32 and ensuring the flow-through effect of the industrial wastewater.

[0047] In an embodiment of the present application, as Figure 3 shown, the impurity removal component 3 may further include a plurality of auxiliary cleaning members 33, and the plurality of auxiliary cleaning members 33 are respectively slidably connected to the corresponding impurity removal plates 32.

[0048] It should be noted that the auxiliary cleaning member 33 described in this embodiment can push the materials on the impurity removal plate 32, so that the materials on the impurity removal plate 32 effectively fall into the aggregate tank 4, avoiding some impurities that are easily adsorbed on the impurity removal plate 32 from being adsorbed on the impurity removal plate 32 for a long time, thereby improving the discharging efficiency of the impurity removal plate 32. In addition, through the sliding connection between the impurity removal plate 32 and the filter plate 20, the impurities on the filter plate 20 can be cleaned, thereby ensuring the filtering effect of the filter plate 20.

[0049] In an embodiment of the present application, as Figure 3 shown, the auxiliary cleaning member 33 may include an electric telescopic rod 330 and a cleaning plate 331.

[0050] Among them, one end of the electric telescopic rod 330 is arranged inside the rotating drum 31, the other end of the electric telescopic rod 330 extends to the outside of the rotating drum 31 and is slidably connected to the cleaning plate 331, and the cleaning plate 331 is slidably arranged on the impurity removal plate 32.

[0051] It should be noted that an elastic rubber pad is provided on the cleaning plate 331 in this embodiment, so as to reduce the friction between the cleaning plate 331 and the impurity removal plate 32 and improve the service life of the cleaning plate 331 and the impurity removal plate 32.

[0052] It can be understood that through the arrangement of the electric telescopic rod 330, the cleaning plate 331 can reciprocate on the impurity removal plate 32, and during the reciprocating movement, the impurities on the impurity removal plate 32 can be cleaned and transported to the aggregate box 4.

[0053] In an embodiment of the present application, as Figure 3 shown, a blockage prevention member 34 is provided on the cleaning plate 331, and the blockage prevention member 34 is rotationally inserted into the corresponding filter hole 320.

[0054] It should be noted that the blockage prevention member 34 described in this embodiment is used to insert into the filter hole 320 on the impurity removal plate 32, so as to throw out the small impurities stuck in the filter hole 320, thereby ensuring the water leakage effect of the filter hole 320.

[0055] In an embodiment of the present application, as Figure 3 shown, the blockage prevention member 34 may include two fixing blocks 340, a roller shaft 341 and a plurality of insertion blocks 342.

[0056] Among them, the two fixing blocks 340 are respectively arranged at both ends of the cleaning plate 331, both ends of the shaft are rotatably connected to the corresponding fixing blocks 340, and the plurality of insertion blocks 342 are respectively arranged on the roller shaft 341, and the plurality of insertion blocks 342 are respectively rotationally inserted into the corresponding filter holes 320.

[0057] It can be understood that through the arrangement of the roller shaft 341, during the process of the insertion block 342 inserting into the filter hole 320, the roller shaft 341 can rotate, so as to facilitate the insertion block 342 to insert into the filter holes 320 in different columns.

[0058] Specifically, in the actual operation process, industrial wastewater flows from the sewage discharge pipe 1 into the filtration tank 2, the filter plate 20 filters the industrial wastewater, leaves the impurities on the filter plate 20, makes the sewage flow from the filtration tank 2 into the discharge pipe 5, and flows from the discharge pipe 5 into the sedimentation tank for purification treatment.

[0059] A controller (not shown in the figure) controls the rotation of the motor 30. The motor 30 drives the rotation of the rotating cylinder 31. The rotation of the rotating cylinder 31 drives the impurity removal plate 32 to rotate on the filter box 2 and the filter plate 20, so as to rotate the impurities in the filter box 2 out and leave the impurities on the impurity removal plate 32. When the impurity removal plate 32 rotates to the aggregate box 4, the controller controls the electric telescopic rod 330 to extend. The extension of the electric telescopic rod 330 drives the cleaning plate 331 to slide on the impurity removal plate 32. And during the sliding process, the insertion block 342 on the roller shaft 341 rotates and inserts into the filter hole 320, and clears the impurities in the filter hole 320. And the cleaning plate 331 pushes the impurities into the aggregate box 4, thus completing the pretreatment of the impurities, and there is no need for relevant operators to clean manually, improving the pretreatment efficiency of industrial wastewater.

[0060] In summary, for the industrial wastewater pretreatment device of the embodiment of the present application, there is no need for manual cleaning of the filter screen, reducing the labor intensity of relevant personnel and improving the pretreatment efficiency of industrial wastewater.
