Application fields of screw press equipment:

Comprehensively solve the treatment of vegetables, fruits, meals and domestic garbage; Biogas residue, sweet sorghum, water hyacinth, cassava residue, straw, sweet potato residue, potato residue, sugarcane residue, algae, various oil residues, waste, methyl cellulose, medical waste, vegetable and fruit waste, kitchen waste and domestic waste; Separation of food wastes, organic compounds and inorganic compounds; Dehydration of livestock and poultry feces, such as feces, sheep feces, duck feces, etc., as well as squeezing and separation of slaughterhouse wastewater.

At present, the screw press is widely used in solid-liquid separation and treatment equipment in food, paper, pharmaceutical, wastewater treatment, harmless, light industry, aquaculture and other industries.

Working principle of the screw press: first of all, extrusion: when the screw promoting shaft body just starts to rotate, various wear-resistant stainless steel plate blades and promoting materials are arranged in the outer field of the screw shaft. Under the action of force, the water will be discharged from the screen gap, and then quickly extruded and dehydrated.

Secondly, dehydration: the materials under pressure will move forward with the rotation of the screw shaft. At the position where the materials are close to the inlet and outlet, the shaft of the screw shaft will gradually become wider, the gap between the blades will gradually become smaller, and the volume of the screw cavity has decreased; Under the action of the resistance pin at the inlet and outlet, the gas pressure increases continuously. Under the action of the screw driving shaft rotation, the water in the material will be extruded and discharged, and the water content of the material will decrease continuously, thus completing the dehydration operation of the material.

Then self-cleaning: the rotation of the screw shaft will continue to rotate, and the machine and equipment will realize a continuous self-cleaning process under the promotion of the screw, so as to better prevent the blockage of the traditional dehydrator.

Common problems of screw press application:

1. Before feeding, the screw press shall seal the cone and the feeding port, and the torque force of the compression spring shall be properly adjusted according to the nut. When the slag skin causes slag resistance, check the expected pressure effect, and then adjust the clamping level and position of the spring appropriately to ensure the expected satisfactory pressure effect.

2. When feeding the screw press, the unclean articles and other articles shall be prevented from being put into the equipment. Thick fruiting branches shall be removed to prevent damage to the screen barrel. The feeding should be as uniform as possible, so that the expected effect can be better.

3. At the end of pressing, the screw press shall relieve the pressure in advance, and the elasticity is yellow, so that the cone moves under the driving of the fruit residue, so that the fruit residue is too solid, which is conducive to the cleaning when it is not used for a long time. The equipment shall be clean and tidy, and the rusted part shall be coated with grease for maintenance.

The screw press is composed of a feeding bin, a press screw and a screw seamless steel pipe Various solid-liquid separation equipment composed of slag discharge pipe and controller equipment. The waste slag to be treated enters the spiral seamless steel pipe from the feed bin and is extruded and dehydrated under the action of the press screw The water extruded from the raw materials is collected to the stainless steel water tank through the filter screen and discharged through the drain pipe. After the raw materials become small, they are discharged through the slag discharge pipe, thus greatly reducing the net weight and capacity of the water tank. Screw press consists of blowdown pipe area, feeding area and screw transport area Composition of feed area. In the water tank feeding area, the water tank is discharged after compaction in the compaction area by the screw press, and the sewage is introduced into the seepage pipe from the water tank.
