Feed Inlet Design for Thickening Equipment

Gravity thickening: This process is mainly carried out in thickening equipment. Its main purpose is to treat sludge and treat pulp. It can also be used to concentrate sludge into primary storage tanks before high-speed digestion. The design of the Thickening Equipment feed port will affect the operating efficiency of the thickened equipment. How do manufacturers design feed inlets? Golden Machinery offers some design ideas.

The thickening device is equipped with a slowly moving vertical blade, like a fence. The sludge is usually continuously transported from the sedimentation tank to the concentrator, which has a low overflow rate, allowing excess water to overflow and the sludge solids to concentrate at the bottom. The sludge layer is controlled to remove and maintain, and can be continuously performed at a low rate. The key component of any thickening device is the feed port, which has the following features:

1. Control energy and momentum dissipation;

2. Feed degassing;

3. Feed dilution (if needed);

4. Optimize flocculation conditions;

5. The feed stream is evenly distributed into the concentrator.

This is the key to introducing uniform concentricity of feed concentrating equipment, considering the downstream factors in the design: the design of the mud treatment system downstream of the thickener depends largely on the application.

Ipsilateral feed inlet

This is the most common feed design in today's industry. Our goal is to have the angular momentum of the feed in the feed opposite the feed port, and then use the momentum as a material to continue the feed port rotation.

Landing gear inlet

The chassis has been used in some thickeners in an attempt to transfer the downward momentum into the slurry.
