Description

TECHNICAL FIELD

[0001] The utility model relates to wastewater treatment technical field, concretely relates to a clean plant air purification air conditioning uses wastewater treatment equipment. BACKGROUND

[0002] In the operation process of the clean plant air purification air conditioning system, wastewater containing various impurities will be generated. These wastewaters not only contain conventional suspended solids, but also may carry tiny particulate matters, organic pollutants and the like generated in the air purification process. The traditional quartz sand filter tank, as a key link in the treatment process of such wastewater, has many drawbacks.

[0003] It usually adopts a single-structure filter layer design, directly laying quartz sand in the filter tank, lacking reasonable layering and convenient operation components. When treating the clean plant air purification air conditioning wastewater, due to the complex impurity composition in the wastewater, the quartz sand filter layer is easily blocked by various pollutants after a period of filtration. During backwashing, the entire filter layer has extremely large resistance, and the water flow is difficult to uniformly and efficiently penetrate, resulting in low backwashing efficiency. This makes it difficult to completely remove the impurities trapped by the quartz sand, seriously affecting the filtration effect of the clean plant air purification air conditioning wastewater. Over a long period of time, the service life of the quartz sand is greatly shortened, and it needs to be frequently replaced, which not only increases the treatment cost, but also may affect the continuous and stable operation of the clean plant air purification air conditioning system due to equipment downtime during replacement.

[0004] In terms of quartz sand replacement, the traditional filter tank is extremely inconvenient to operate. For the clean plant air purification air conditioning wastewater treatment equipment, each time the quartz sand is replaced, the staff needs to first drain the wastewater in the filter tank. Considering the possible pollutants in the wastewater, this process needs to be particularly cautious to prevent wastewater leakage from polluting the environment. After draining, the old quartz sand is manually cleaned, which is tedious and time-consuming. At the same time, due to the lack of convenient disassembly and assembly structure, the new quartz sand is difficult to fill, and it is difficult to ensure uniformity, which directly affects the filtration performance of the subsequent clean plant air purification air conditioning wastewater. In addition, the traditional filter tank needs to be filled with quartz sand on site during assembly. The clean plant has very high requirements for environmental cleanliness, and on-site filling operations are prone to dust pollution, and the limited working environment makes the assembly efficiency low, which is difficult to meet the needs of large-scale construction and rapid equipment installation in the clean plant.

For ordinary skilled in the art, can understand the specific meaning of the above terms in the utility model with specific circumstances.

[0024] The utility model will be further explained in detail in combination with examples:

[0025] Example 1

[0028] The bottom surface of receiving frame 10 is overlapped with the upper surface of lower combined filter layer 8, the upper side of quartz sand filter tank 1 is provided with water inlet pipe 2, one side of quartz sand filter tank 1 is fixedly connected with filter drainage pipe 3.

[0029] The back of quartz sand filter tank 1 is fixedly connected with backflushing drainage pipe 5, one side of quartz sand filter tank 1 is fixedly connected with backflushing water inlet pipe 4.

[0030] Example 2

[0031] As Figures 1-4 Indicated, based on the utility model provides a kind of technical scheme on the basis of example 1: preferably, assembly frame 9 is rotatably connected with turnover closure plate 12 on one side near bottom end by shaft seat 14, one side of turnover closure plate 12 near top end is fixedly connected with positioning ring 16, the number of turnover closure plate 12 is two groups, two groups of turnover closure plate 12 are symmetrically distributed on the two sides of assembly frame 9.

[0032] The inner wall of positioning ring 16 is inserted with plug 17, the top end of plug 17 is fixedly connected with limiting rod 15.

[0033] One side of turnover closure plate 12 is fixedly connected with protective net 13.

[0034] The working principle of the wastewater treatment equipment for air purification and air conditioning in this cleanroom will be explained in detail below.

[0035] like Figures 1-4 As shown, when the quartz sand in the quartz sand filter tank 1 has been used for a long time, it needs to be backwashed or replaced.

[0036] During backwashing, the assembly frames 9 in the upper combined filter layer 7 can be lifted one by one to separate them from the quartz sand filter tank 1. After the upper combined filter layer 7 is removed from the lower combined filter layer 8, the backwash water pump is connected through the backwash water inlet pipe 4 to deliver cleaning water. At this time, since only the lower combined filter layer 8 is placed in the quartz sand filter tank 1, the resistance during the backwashing process is reduced, thus improving the rinsing efficiency of the lower combined filter layer 8 and enhancing the backwashing effect.

Then, the limiting rod 15 in the assembly frame 9 is removed to release the restriction on the flip-top sealing plate 12. The flip-top sealing plate 12 is then flipped to both sides to release the seal on the quartz sand, allowing the quartz sand in the assembly frame 9 to be quickly cleaned out. When filling with new quartz sand, the operation is reversed.

[0039] Since the upper combined filter layer 7 and the lower combined filter layer 8 are composed of multiple sets of assembly frames 9, when assembling the upper combined filter layer 7 and the lower combined filter layer 8, the assembly frames 9 for assembling quartz sand can be placed in the corresponding layers in advance, and then combined and stacked.

[0040] The quartz sand filling the upper combined filter layer 7 and the lower combined filter layer 8 is laid in a pattern of starting with finer particles and gradually increasing in size from top to bottom.

[0041] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
