The spiral dehydrator is a device that uses physical extrusion to dehydrate. The equipment consists of a drive system, a feed box, a screw auger, a screen, a pneumatic blocking device, a water collection tank, a rack, etc. The material enters the equipment from the feed box and is gradually squeezed under the transportation of the spiral auger. The excess water is discharged from the drainage outlet through the screen. Under the continuous transportation of the spiral auger, the top-opening blocking equipment is discharged from the discharge outlet.

Structural description of spiral dehydrator parts:

1. Guide rollers and leaves

The lead of the spiral guide roller adopts a non-fixed pitch spiral, the blades (high toughness and wear-resistant materials) adopt structural types of different depths, and the roller shaft and blades are welded together. The blades form a continuous spiral curved surface along the surface of the roller shaft with a special taper. Since the lead and groove depth gradually decrease from the feed to the discharge end, the material moves forward along the spiral groove, and the material continues to be axially and radially Squeeze so that the liquid is continuously separated through the dehydration system.

2. Separate grid, separate net

The separated grid adopts straight tube and steel frame structure. And fixed on the fuselage with bolts to support the pressure during extrusion. The separation mesh frame is welded and combined with stainless steel separation mesh points. The separation mesh is divided into round hole type and slot mesh type Ф0.2~Φ3mm, which is beneficial to better filtering the liquid in the material. The gap between the diameter of the guide roller blade and the separation net shall not be greater than 2mm.

The spiral dehydrator can continuously extract high-humidity materials:

The spiral dehydrator is widely used and can be used for residues, maltitol, wine troughs, food waste, fruits and vegetables, straw pulp, straw, etc.

As a new type of dehydrator, the mechanical equipment can carry out dehydration work continuously and has high work efficiency. Compared with traditional dehydration methods, it has the advantages of good dehydration effect, high work efficiency, low energy consumption, and simple actual operation.

The spiral dehydrator is a more practical mechanical equipment. It reduces everyone's labor intensity in application. Only one device is needed to perform a large number of practical operations. It can not only improve everyone's working environment and make everyone's work more efficient. Comes simpler and easier.

The principle of the spiral dehydrator is mainly based on extrusion molding to squeeze out the liquid in the material. The extruded liquid is discharged through the stainless steel screen, and then all collected in the water storage tank and discharged through the drainage pipe. After dehydration, the material passes through the stainless steel screen tail inlet and outlet cleaning equipment.

Practicality of spiral dehydrator:

The transport spiral pushes the material entering the material box to the spiral in the pressure area. By reducing the tooth pitch and increasing the shaft diameter, under the action of the resistance of the screen wall and the cone, the material is gradually concentrated and the contained liquid is squeezed out. The squeezed liquid flows out from the screen, is concentrated in the water storage tank, and is discharged from the water tank. The dehydrated dry material passes through the discharge machine between the end outlet of the screen barrel and the automatic cylinder resistance equipment body.

The rear of the machine's discharge port is equipped with a cylinder automatic resistance device. By adjusting the pre-tightening force and position, the drainage resistance and the size of the slag discharge port can be changed, and the dry humidity of the dewatered material can be adjusted (adjusted according to the user's actual usage).
