Problems solved by technology

[0004] (1) Only applicable to small water plants;
[0005] (2) The filter layer cannot be seen during operation;
[0006] (3) The sand discharge port is small and the sand discharge is inconvenient;
[0007] (4) The equipment is generally small and the water volume is limited;
[0008] (5) It takes time and effort to change the filter material
Fully-sealed pressure vessels are not suitable for making too large, inconvenient to carry, and the cost is relatively high

Embodiment Construction

[0048] like figure 1 As shown, this embodiment provides a pressure filter tank, the pressure filter tank includes a pressure filter tank body and a cleaning fluid assembly;

[0049] The pressure filter tank body is the structure and shape of a commercially available pressure filter tank, and the focus of this embodiment lies in the transformation of this type of conventional pressure filter tank;

[0050] The top of the pressure filter tank body has an upper manhole, and the bottom has a lower manhole and an outlet hole;

[0051] The lower manhole is an openable and closable structure, and is fixedly arranged between the outlet hole and the pressure filter tank body;

[0052] The top of the pressure filter tank body also has two lifting lugs, and the main part of the equipment can be opened by exerting upward force on the two lifting lugs;

[0053] The left side of the pressure filter tank body is provided with a water inlet above and a discharge hole below;

[0054] The en...

Abstract

The invention provides a kind of sand tank online regeneration method, it is characterized in that, it is realized by the following steps: S1. adopt cleaning agent I to carry out at least one cycle cleaning to the sand in the sand tank; S2. adopt cleaning agent I to The sand in the sand tank is soaked and cleaned at least once; S3. the sand in the sand tank is cleaned with water; the cleaning agent 1 is an acid comprising at least two. The method can realize online cleaning without frequent tank opening.

Description

technical field [0001] The invention belongs to the maintenance field of pretreatment equipment, and in particular relates to an online regeneration method for sand tanks. Background technique [0002] In the water treatment process, pretreatment is an extremely important link, and the filtration link is generally one of the indispensable conditions in the water treatment process. Generally, the filter container is selected from ordinary fast filter, double-valve filter, multi-layer filter material filter, siphon filter, valveless filter, mobile cover filter, pressure filter tank, microfilter, replica valve filter, etc. Among them, the pressure filter tank is easy to move, easy to mount, slow down and settle, and has better water quality, and is the most widely used in small water stations. [0003] The disadvantages of the existing processing technology are as follows: [0004] (1) Only applicable to small water plants; [0005] (2) The filter layer cannot be seen during...
