Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and in particular relates to a multi-stage filtration wastewater treatment device. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. It is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, healthcare, and catering, and is increasingly becoming a part of everyday life. Classified by wastewater source, wastewater treatment is generally divided into industrial wastewater treatment and domestic wastewater treatment. Industrial wastewater includes industrial wastewater, agricultural wastewater, and medical wastewater, while domestic wastewater is wastewater generated in daily life. It refers to a complex mixture of various forms of inorganic and organic matter, including: floating and suspended solid particles of various sizes; colloidal and gel-like diffuses; and pure solutions. Wastewater treatment requires filtering and separating solid particulate impurities from the wastewater.

[0003] In existing wastewater filtration treatment processes, particulate matter in the wastewater can easily clog the filter screen, thus affecting the efficiency of wastewater filtration. Furthermore, floating plastic bags in the wastewater can also negatively impact wastewater treatment. Utility Model Content

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0036] It is understood that the terms “first” and “second” as used herein may be used to describe various elements, but unless otherwise stated, these elements are not limited by these terms. These terms are used only to distinguish one element from another.

[0037] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0038] like Figures 1 to 5 As shown, a multi-stage filtration wastewater treatment device according to one embodiment of the present invention includes:

[0039] Filter box 1 is equipped with water inlet assembly 2, filter debris plate 4, filter cotton plate 5 and activated carbon filter plate 6, which are used for multi-stage filtration of sewage.

[0040] Backwash assembly 3, disposed on filter box 1, is used to backwash filter impurity plate 4. Backwash assembly 3 includes:

[0041] The delivery pump 31 is fixedly mounted on the support plate, which is fixedly mounted on the filter box 1. The inlet end of the delivery pump 31 is connected to the filter box 1 through a pipe, and the outlet end of the delivery pump 31 is connected to the distributor 33 through the delivery pipe 32.

[0042] A time relay is also fixedly installed on the delivery pump 31;

[0043] The distributor 33 is fixedly installed on the filter box 1 and is used to split the liquid.

[0044] Backflush pipes 34 are installed on filter box 1. Multiple backflush pipes 34 are connected to distributor 33 through infusion pipes. One-way valves are installed on the infusion pipes. Backflush nozzles 35 are installed on multiple backflush pipes 34.

[0045] In this embodiment of the present invention, in practical application, sewage flows from the inlet component 2 into the filter box 1, and undergoes multi-stage filtration through the filter plate 4, filter cotton plate 5, and activated carbon filter plate 6. Since the time relay controls the start and stop of the delivery pump 31 at regular intervals, when the delivery pump 31 starts, it draws out the filtered sewage and then sprays water from the backwash nozzle 35 through the delivery pipe 32, the diverter 33, and the backwash pipe 34 to backwash the holes on the filter plate 4, so that the blocked particles are swept off and the filter plate 4 is prevented from affecting the treatment of sewage.

[0046] By setting up the backwash component 3, the filter plate 4 can be backwashed during multi-stage filtration of sewage, so that the clogging particulate impurities are impacted and dislodged, avoiding long-term clogging of the filter plate 4 by particulate matter, thereby improving the efficiency of sewage treatment.

[0047] like Figure 2 , Figure 3 and Figure 4 As shown, in a further embodiment of this utility model, the water inlet assembly 2 includes:

[0048] The inlet tank 21 is fixedly installed on the filter box 1 and is used to transport sewage.

[0049] Support frame 22 is fixedly installed on water inlet tank 21;

[0050] The rotating roller 23 is rotatably mounted on the support frame 22;

[0051] The intercepting rod 24, and multiple conveying intercepting rods 24 are all fixedly installed on the rotating roller 23, and fixed hooks are fixedly installed on the multiple intercepting rods 24;

[0052] The water inlet pipe 25 is fixedly installed on the water inlet tank 21;

[0053] Clean the sealing cover 26, which is movably installed on the water inlet tank 21;

[0054] In this embodiment of the utility model, in actual application, sewage flows into the inlet tank 21 through the inlet pipe 25. The floating plastic bag debris in the sewage is hooked by the rotating roller 23, the intercepting rod 24 and the fixing hook, and separated from the sewage. Finally, the cleaning sealing cover 26 is opened to collect and clean the floating plastic bag debris.

[0055] like Figure 5 As shown, in a further embodiment of this utility model, a floating component 7 is also included, disposed on the filter box 1, for cleaning the filter plate 4. The floating component 7 includes:

[0056] Positioning rod 71 is fixedly installed on filter box 1;

[0057] The positioning frame 72 is slidably engaged with the positioning rod 71;

[0058] Support rod 73 is fixedly installed on positioning frame 72;

[0059] Airbag 74 is fixedly mounted on support rod 73;

[0060] The cleaning brush 75 is fixedly installed on the positioning frame 72;

[0061] In this embodiment of the present invention, during actual application, the airbag 74 is affected by the height of the sewage flow, which causes the positioning frame 72 to move through the positioning rod 71, so that the cleaning brush 75 is moved synchronously. When the cleaning brush 75 moves, it can clean the surface of the filter plate 4, reducing the probability of particulate impurities clogging the filter plate 4.

[0062] like Figure 2 and Figure 4As shown, as a further embodiment of the present utility model, the filter box 1 is also equipped with a disassembly sealing cover 11 for sealing the filter box 1, and the filter box 1 is also equipped with a water outlet pipe 12 for discharging the filtered sewage.

[0063] Specifically, as a further embodiment of this utility model, the filter plate 4, the filter cotton plate 5, and the activated carbon filter plate 6 are all slidably fitted with the filter box 1, and an ultraviolet lamp is also fixedly installed on the filter box 1 for sterilizing the inside of the filter box 1.

[0064] In this embodiment of the utility model, in practical application, wastewater is filtered through multiple stages using filter plates 4, cotton filters 5, and activated carbon filters 6. Furthermore, by removing the sealing cover 11, the filter box 1 can be easily opened to replace the filter plates 4, cotton filters 5, and activated carbon filters 6.

[0065] like Figure 2 and Figure 4 As shown, in a further embodiment of this utility model, the delivery pump 31, delivery pipe 32, flow divider 33, backflush pipe 34 and backflush nozzle 35 constitute the liquid flow path;

[0066] In this embodiment of the utility model, in actual application, the water is divided into multiple flow directions by the delivery pump 31, delivery pipe 32 and diverter 33, so that multiple reverse water flows are sprayed out through the backwash pipe 34 and backwash nozzle 35 to backwash the filter plate 4.

[0067] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
