For printing and dyeing sludge pressing, slow feed and filter cloth sticky problems, the following are some possible causes and corresponding solutions:

Reasons and solutions for printing and dyeing sludge pressing out

Cause:

Sludge properties: printing and dyeing sludge usually contains a large number of toxic and harmful substances, which is difficult to adjust, and the sludge particles may be small, and it is not easy to form large particles to be intercepted by the filter cloth, resulting in poor dehydration effect.

Improper selection of agents: wrong selection of agents or insufficient dosage, poor coagulation and flocculation effect of sludge, high water content.

Equipment problems: there may be faults in the filter press equipment, such as insufficient feed pressure caused by the failure of the feed pump, or improper selection of filter cloth, cleaning is not clean.

Solution:

Select the right sludge conditioner and flocculant: according to the characteristics of printing and dyeing sludge, select the right sludge conditioner and flocculant to improve the dewatering effect of sludge.

Adjust the dosage of the agent: according to the nature and concentration of the sludge, adjust the dosage of the agent to ensure the best coagulation and flocculation effect of the sludge.

Check and repair equipment: regularly check the equipment status of the filter press, such as the feed pump, filter cloth, etc., to ensure its normal operation. If there is a fault, timely repair or replacement.

Two, slow feed reasons and solutions

Cause:

Pump body problem: the structure of the pump body and pump frame of the slime pump is unreasonable or seriously worn, resulting in reduced pump water efficiency.

Inlet end blockage: there are lumps and foreign bodies in the inlet pipeline, which hinder the flow of slime.

Solution:

Replace or repair the pump body: if the pump body and pump frame are worn or the structure is unreasonable, it needs to be replaced or repaired in time.

Clean the inlet end: clean the inlet pipe regularly to ensure that there is no accumulation, foreign matter and other obstacles to the flow of slime.

Three, the causes of sticky filter cloth and solutions

Cause:

Sludge properties: The viscosity of printing and dyeing sludge is higher, and it is easy to adhere to the filter cloth.

Filter cloth cleaning is not thorough: the filter cloth has not been thoroughly cleaned for a long time, resulting in blockage and adhesion.

Solution:

Select the right filter cloth: Select the right filter cloth material and specifications according to the nature of the sludge to reduce the adhesion of the sludge.

Strengthen filter cloth cleaning: regularly clean the filter cloth to ensure that its surface is clean and reduce the adhesion of sludge.

In summary, aiming at the problems of printing and dyeing sludge not pressing, slow feeding and sticky filter cloth, it is necessary to conduct comprehensive analysis and treatment from many aspects such as sludge properties, agent selection, equipment status and filter cloth cleaning. Through reasonable measures and solutions, the dewatering effect of sludge and the operation efficiency of equipment can be effectively improved.
