Filter Press Unloading Shovel

Filter Press Unloading Shovel

A filter press unloading shovel is a specialized tool used for cleaning filter cake from a filter press. Designed specifically for filter press discharge operations, it is primarily used to thoroughly remove filter cake remaining on the filter plates after filtration.

The unloading shovel is usually made of polypropylene and has a special shovel angle and edge design that can effectively fit the filter plate surface, ensuring that the filter cake is cleaned and ready for the next filtration cycle. This improves discharge efficiency, reduces manual labor intensity, and avoids damage to the filter cloth.

How to Use a Discharge Shovel?

1. Shutdown Preparation: Ensure the filter press has completely stopped, pressure has been released, and the filter plates are open.
2. Safety Check: Wear personal protective equipment (PPE) such as protective gloves and goggles, and check that the discharge shovel is intact.
3. Scooping the Filter Cake: Insert the discharge shovel between the filter plate and the filter cake at an appropriate angle. Apply moderate force and push steadily along the surface of the filter plate to remove the filter cake from the filter plate.
4. Cleaning Corners: Use the edge or tip of the unloading shovel to carefully remove any residual material from around the filter plates and in the grooves.
5. Checking Cleanliness: Ensure the filter plate surface is clean and free of residual material that could affect the seal of the filter cloth and subsequent filtration.
6. Tool Cleaning: Clean the discharge shovel promptly after use to keep it clean and extend its service life.

Operating tips

1. Apply moderate and even force when scraping to avoid damaging the filter plate or filter cloth.
2. Maintain a suitable scraping angle, typically 15-30 degrees.
3. If the filter cake adheres firmly, rinse it with water to soften it before scraping.
4. Do not pry or strike the filter plate with the scraper.

Advantages of a Filter Press Unloading Shovel

• Efficient discharge
  After filtration, the filter cake may adhere to the filter cloth, especially for highly viscous or high-viscosity materials. An unloading shovel can quickly remove this.
• Protecting the filter cloth
  Directly scraping the filter cake with hard objects can easily damage the filter cloth. A discharge shovel made of suitable material and design can remove the filter cake without damaging the filter cloth.
• Reduce labor costs
  In automated unloading systems, the unloading shovel can be combined with a vibrator or robotic arm to reduce manual labor.
• Improve work efficiency
  Compared to manual cleaning or conventional tools, the dedicated unloading shovel removes filter cake quickly and thoroughly, significantly reducing unloading time and improving overall production efficiency.
• High adaptability
  It can be used with filter presses of various models and specifications, and is suitable for handling filter cakes of various viscosities and moisture levels, encompassing a wide range of applications.
• Economical and practical
  With its moderate price and simple maintenance, it is a cost-effective tool for improving filter press operating efficiency.

Precautions for Use

1. Unloading operations must be performed only after the filter press has been completely shut down and pressure has been released.
2. Always wear personal protective equipment, such as protective gloves and goggles.
3. Be aware that the filter cake may contain corrosive or toxic substances; take appropriate precautions.

Maintenance Recommendations

1. Clean the shovel after each use to prevent residual material from corroding the shovel surface.
2. Inspect the shovel surface regularly for wear and replace if severely worn.
3. Store in a dry, ventilated area to avoid moisture that may cause rust.
4. Metal shovels can be regularly treated with rust-inhibiting oil.
