Pay attention to maintenance and management when not using screw press at ordinary times:

When not in use at ordinary times, check whether the inside of the screw press equipment is cleaned, such as whether there is dirt adhesion on the filter belt. The filter belt is often too worried. Pay attention to check for damage. Residue and damage will endanger the normal operation of the equipment. Therefore, in this case, the dirt should be cleaned in time, and the damaged parts should be removed and replaced. The drain outlet of the liquid collecting tank is the part that discharges the liquid that solves the material. Pay attention to check whether it is unblocked or blocked.

When cleaning the screw press, pay attention to the operation steps, carefully clean some deposits with strong adhesion and difficult to clean, to prevent the incorrect application of special tools when scraping off, causing damage and corrosion to the equipment surface.

Inspection process of screw press:

Generally speaking, the inspection process of screw press is from switch power supply, cyclone switch to screw shaft, conveyor belt, etc. Before the on-board inverter, check whether the power circuit is firmly connected, intact and accurate, and then plug it in. Turn on the power switch of the pneumatic valve as the main control box to display the gas. Then check each pneumatic component for air leakage, blockage and other adverse conditions. Check whether the conveyor belt is suitable, open the centrifugal pump used to clean the conveyor belt, check whether there is water seepage in each pipeline and whether the water flow is normal.

When cleaning the press, the dirt on the shell should be cleaned, but the motor, switch power box and other connecting power circuits should be prevented from contacting with water. When the equipment is running, check whether the screws at each connection position are loose and whether there are cracks at the welding position with the vibration.

As a kind of slag solid-liquid separation mechanical equipment, it is more important to check the screw press during operation. It can check whether the equipment can work properly. If there is a problem, it can be found and solved as soon as possible to reduce the probability of common faults in equipment operation.

How to solve the problem of material jam of screw press?

The principle of the traditional screw press is to continue to transport the material in the feed hopper from the feed end to the feed end according to the promotion of the screw, reduce the volume of the material according to the mutual restriction between the charging and discharging door and the screen, and then discharge part of the liquid according to the screen under the action of the screw extrusion pressure. When the feed hopper stops feeding, the dense material between the screw and the screen loses the driving force of continuous feeding, and is stuck between the screen and the screw and cannot be cleaned. In the early stage, the screw press used manpower to open the screen and clean up the materials stuck in the middle. Some processes without hygiene requirements cannot consider cleaning materials, but process some food materials, some materials with chemical change and taste caused by normal temperature and gas, and cannot accept materials that exist between spiral and screen for a long time, and need to be cleaned every time the equipment is used.

By adjusting the overall design of the screw, the new screw press can discharge the residue between the screen and the screw under the working condition of terminating the feeding, and install mobile spray equipment outside the screen to complete the spray cleaning of the juice tray outside the screen.
