Feed inlet is equipped with discharge port far from the side of feed inlet in the shell, and the housing bottom middle position is equipped with water outlet, institute
Water outlet connection vacuum tank is stated, the exit of the vacuum tank connects peristaltic pump.
Preferably, strainer is installed in the feed inlet lower end peripheral, to ensure that the area of drainage increased, so that low concentration
Material enters in dewaterer without other filter methods to be dehydrated.
Preferably, the shell uses 304 stainless steel materials, and the shell is equipped with observation window, and the observation window uses
Organic glass material.
Preferably, the exit of the peristaltic pump connects Microfilter, can carry out secondary filter to the water of removing.
Compared with prior art, the utility model has the following beneficial effects:
(1) spiral dewaterer described in the utility model installs strainer in feed inlet lower end peripheral, can increase drainage
Area；
(2) guarantee that dehydration is stablized in water outlet connection vacuum tank to carry out；
(3) moisture and air in confined space are extracted using peristaltic pump after being sealed to the dewaterer, so that close
Close in space pressure to increase, material be dehydrated using vacuum internal pressure, can effectively remove the moisture in material cell pipe with
And the existing moisture that flows back of dehydration equipment, improve dehydration rate；
(4) secondary filter can be carried out to the moisture of removing by connection Microfilter, reduces waste；
(5) the utility model structure is simple, easy to operate, and will not damage institute using dewaterer described in the utility model
The fiber of de- material, the dehydration mass dryness fraction under the compression ratio of the dehydration mass dryness fraction ratio 1:400 under the compression ratio of 1:300 improve
18%-20% greatly reduces specific energy consumption, improves economic benefit.

[specific embodiment]
To keep the purpose of this utility model, technical solution and advantage clearer, in the following with reference to the drawings and specific embodiments,
The utility model is described further.
As shown in Figure 1 be the main view of vacuum screw dewaterer described in the utility model, the dewaterer include bracket 1 with
And driving part and dehydration part on bracket 1 are set, the driving part includes sequentially connected motor 2 and retarder 3；
The dehydration part includes the shell 4 of coaxial arrangement, and the shell 4 is set as sealing structure, and observation is equipped on the shell 4
Window 41, convenient for observing the cases of dehydration of dewaterer materials inside；It is equipped with feed inlet 7 on the top of shell 4, the shell 4 is separate
The side of feed inlet 7 is equipped with discharge port 8, and the bottom middle position of the shell 4 is equipped with water outlet 9, and the water outlet 9 connects surely
Tank 10, the horizontal placement of the vacuum tank 10 are pressed, import and outlet asymmetry opening, import are connect with water outlet 9, the vacuum tank
