Problems solved by technology

[0002] Sewage with relatively low solid content, or sludge with low concentration, is quite time-consuming and inefficient in purification treatment
At present, the more common treatment method is to pre-precipitate the mud-water mixture to remove part of the sludge; the disadvantage of this method is that, first, it needs to build a sedimentation tank, which occupies a large area and increases the cost; second, it needs to be treated The amount of sewage is still huge, and it still takes a long time if the power of the filter press remains unchanged

Embodiment 1

[0019] The sludge pre-thickening device in this example, such as figure 1 As shown, it includes sludge inlet 1, sludge outlet 2 and sludge conveying channel 3; sludge inlet 1 is set at the top of the sludge pre-concentration device, and sludge outlet 2 is set at the bottom of the sludge pre-concentration device; The sludge conveying channel 3 is inclined from top to bottom to connect the sludge inlet 1 and the sludge outlet 2; the sludge conveying channel 3 is provided with at least one filter layer 31, and the filter layer 31 divides the sludge conveying channel 3 into two parts. part, the upper part is the sludge channel, and the lower part is the filtered water channel 32, and the water in the sludge can be carburized to the filtered water channel 32 through the filter layer 31; The sludge outlet 2 is isolated from the filtered water outlet 33 . The filtering layer in this example is as figure 2 As shown, the non-woven fabric layer with multi-layer structure is used. In ...

Embodiment 2

[0023] The sludge pre-thickening device of this example has the same basic structure as that of Embodiment 1, as image 3 As shown, only a plurality of protrusions 311 are designed on the surface of the filter layer 31 .

[0024] The sludge pre-concentration device in this example uses the design of the protrusion 311 to mix the sludge on the surface layer and the inner layer, thereby improving the effect of water separation. The sludge pre-concentration device in Example 1 is used for the same sludge , and the raised sludge pre-thickening device of the design of this example, the water separated in this example is obviously more than that of Example one. It can be seen that the sludge pre-thickening device in this example has a better pre-thickening effect.

Abstract

The invention discloses a pre-concentration device of sludge. The pre-concentration device of sludge comprises a sludge inlet, a sludge outlet and a sludge conveying passage; the sludge inlet is formed in the top of the pre-concentration device of sludge, the sludge outlet is formed in the bottom of the pre-concentration device of sludge; the sludge conveying passage is inclined to communicate the sludge inlet with the sludge outlet; a filter layer is arranged on the sludge conveying passage, and divides the sludge conveying passage into two parts which are independent and parallel, the upper part is a sludge passage, and the lower part is a filtered water passage; a filtered water outlet isolated from the sludge outlet is formed in the bottom of the pre-concentration device of sludge. According to the pre-concentration device of sludge disclosed by the invention, the filter layer is arranged on the sludge conveying passage, and the water is separated by using the process that the sludge naturally flows from a high place to a low place. The pre-concentration device of sludge disclosed by the invention has the advantages that the structure is simple, the operation is convenient, additional power equipment is not needed in the whole water filtration process, and energy conservation and environment protection is realized. Through the treatment of the pre-concentration device of sludge, the amount of sludge treatment is greatly reduced, and the sludge treatment efficiency is improved.

Description

technical field [0001] The application relates to the field of sewage treatment, in particular to a sludge pre-concentration device. Background technique [0002] Sewage with relatively low solid content, or sludge with low concentration, is quite time-consuming and inefficient for purification treatment. At present, the more common treatment method is to pre-precipitate the mud-water mixture to remove part of the sludge; the disadvantage of this method is that, first, it needs to build a sedimentation tank, which occupies a large area and increases the cost; second, it needs to be treated The amount of sewage is still huge, and it still takes a long time when the power of the filter press remains unchanged. Contents of the invention [0003] The purpose of this application is to provide a sludge pre-thickening device with a new structure. [0004] The application adopts the following technical solutions: [0005] The application discloses a sludge pre-concentration dev...
