Safety measures:

When a blockage occurs, the controller will stop the crusher in both on/automatic modes and reverse it to clear obstacles. After the blockage is cleared, the controller will resume normal operation. If the blockage still exists, the controller automatically executes the reverse process within 30 seconds, up to three times. If the blockage still exists after three reversals, the controller will cut off the power supply to the motor and activate the delay and abnormal status indicator lights.

If there is a sudden power outage while the crusher is operating normally, the crusher will resume normal operation once the power supply is restored.

If the crusher stops running abnormally and suddenly loses power, the abnormal status indicator light will automatically start when the power is restored.

The controller provides motor overload protection through an overload protection relay installed on the crusher starter.

Short circuit protection is achieved by installing another appropriately sized circuit breaker or fuse.

The reset of the controller is controlled by the local switch panel.

The starter is a full voltage reversing type, using a 120 volt coil. The forward and reverse contactors have electric and mechanical linkage devices, and the overload delay can be adjusted. The adjustment range includes full load current and service factor.

Purpose:

It is a new type of sewage treatment equipment developed for the treatment of solid substances mixed in sewers. This function intercepts solid objects such as cloth, wood chips, empty bottles and cans mixed in the sewer through the grille and sends them to the crusher for crushing. Water flows through the grille to prevent blockage of the sewer water treatment equipment and ensure its normal operation. This device can be used in conjunction with traditional pumping stations or independently, and is mainly suitable for sewage treatment plants and transfer pumping stations.

The items that this machine can crush include: rags, glass, paper products, wooden products, physiological products, empty cans, waste, rubber products, ropes, hoses, leather products, plastic products, etc.

Pump protection: Install a single unit crusher before the current and backup pumps to purify solid debris, prevent blockages, and help maintain pump efficiency.

Sludge: The crusher is used to grind the sludge carried by sewage treatment plants. After the sludge is evenly crushed, the efficiency of the sludge decomposition device can be improved.

Industrial wastewater: Many industrial fields require wet fluid grinding operations. From poultry manure to drilling debris generated by oil drilling platforms, crushers can be used for degradation treatment to protect process equipment.

Time and time again, practice has proven that our crushers provide cost-effective solutions to many problems that customers previously thought could not be solved.

The crushing type grille adopts a dual axis design, with unique cutting blades and washers installed on two parallel rotating axes, alternately overlapping to achieve spiral cutting, which is at an advanced level in precision, strength, and efficiency. The cutting blade and gasket have a hexagonal shape inside and are installed on a hexagonal drive shaft to form a crushing unit that thoroughly crushes solid particles in wastewater. This has created favorable conditions for implementing a fully enclosed design of buried pumping stations, saving civil construction costs and beautifying the environment.

Scope of application:

Applied to buried pump stations, inlet pipelines, etc; Used in conjunction with traditional grilles for garbage disposal;

Applied to sedimentation tanks, digestion tanks, and sludge dewatering systems; Sewage collection system;

Applied to filtration at the inlet of water intake projects; Entrance project of the diversion canal.
