Complete set of sand washing sewage equipment

Date: Nov. 11, 2021

Given the importance of sewage treatment and recycling in the sand washing industry, scientific methods need to be used in actual work to continuously optimize sewage treatment measures. Based on protecting the water environment, solving the outstanding problems of all aspects of sewage treatment technology, and continuously improving the reliability of sewage treatment can there be a sustainable future direction. The following summarizes the complete set of LZZG sand washing sewage equipment.

Concentration tank

1. Thickener

The concentration tank developed by LZZG is based on traditional vertical flow sedimentation equipment. The structure of the internal feed barrel is improved, which greatly improves the efficiency of sedimentation. The plane of the tank body is circular, the suspended matter settles into the cone-shaped sludge bucket at the bottom of the tank under the action of gravity, and the clarified water is discharged from the overflow weir around the upper end of the tank. The overflow port is equipped with a scum filter and baffle to ensure the quality of the effluent. The concentration of the underflow can reach 70%, and the processing capacity is 3-8 times higher than that of the traditional thickener. Solid-liquid separation equipment based on gravity sedimentation. When working, the solid particles suspended in the slurry in the cone of the thickener settle under the action of gravity, and the upper part becomes clarified water so that the solid liquid can be separated. The slurry wastewater with a solid content of 2% to 15% can be settled by gravity and raised to a concentration of 60% to 70% slurry. The upper part of the tank can achieve clear water overflow, to achieve the purpose of sewage purification and solid-liquid separation.

Feeding concentration: ≤15%

Processing capacity: 50t/h-200t/h

Applicable materials: sand, quartz sand, river pebble, granite, limestone, basalt, coal gangue, weathered sand, river sand, and many other materials.

Application range: This equipment has been widely used in various industries such as sand quarries, sand and aggregate plants, precious metal concentrators, ceramics, and glass.

Product features: It adopts the working principle of suspension filtration, media adsorption, and precipitation, no purification membrane, no wearing parts. The tank body is made of high-quality carbon steel (or stainless steel, epoxy glass fiber reinforced plastic, etc.), which has good strength and corrosion resistance. The medicament use cost is low, the processing volume is large, the processing efficiency is high, and the performance is stable. Small size, small footprint, convenient and quick installation. The service life of the whole machine is 10-15 years, the one-time investment is small, and the economic benefits are significant. The processing capacity is higher than that of the traditional thickener, and the overflow water quality can meet the national discharge standards.

Automatic dosing system

2. Automatic dosing system

A certain proportion of catalytic agent solution needs to be added regularly and quantitatively. The JY series automatic dosing system is a professional dosing system for adding chemical solutions in the sewage treatment process with related equipment. Its equipment is widely used in power plants, chemicals, water plants, and aggregate processing tailwater. Purifiers and flocculation are required. The water treatment system of the agent can provide continuous and stable required agents for water treatment.

Composition structure: solution tank, agitator (optional), metering pump, control cabinet, pipeline, buffer, pressure gauge, Y-type filter, liquid level gauge, liquid level sensor (optional), conductivity (optional), PH meter (optional), corrosion online monitor (optional) bracket and other components.

Equipment function: adding flocculant, disinfectant, acid, and alkali solution in water treatment; adding scale inhibitor, water quality stabilizer, etc. to cooling water and circulating water; adding acid and alkali solution to other solutions in the chemical industry, printing, and dyeing industry.

Product features: All components of the dosing device are centrally installed on a rack, which is compact and reasonable combined into an independent dosing unit, which greatly reduces the workload of structural design and on-site installation, and reduces the floor space. Fully automatic mixing, automatic adding, saving human resources. The solution tank is equipped with a plate level gauge, which can realize on-site display and has the protection function of stopping the pump at a low liquid level. It can realize the on-site manual adjustment of dosing and automatic dosing. All electrical appliances and meters are assembled in the electrical cabinet. The structure is compact, and the commissioning and operation are safe and convenient. It can realize a continuous supply of medicine, saving time and dosage of medicine.

Filter press

3. Filter press

The chamber filter press is a kind of mud treatment equipment developed for the realization of solid-liquid separation in industrial production. It is mainly used in chemical, ceramics, petroleum, medicine, food, smelting, and other industries, and is also suitable for industrial filtration of sewage slurry treatment. This equipment has the advantages of convenient operation and maintenance, reliable operation, and so on. The mud cake filtered by the filter press has a higher solid content and a good separation effect.

Feeding concentration: 20-40%

Processing capacity: 0.8t/h-12t/h

Filtering area: 50㎡-500㎡

Applicable materials: sand, quartz sand, river pebble, granite, limestone, basalt, coal gangue, weathered sand, river sand, and many other materials.

The product features a simple structure, easy operation, stable operation, and convenient maintenance. Few wearing parts and low maintenance cost. The filter area can be selected flexibly and occupies a small area. It has strong adaptability to materials and is suitable for various small and medium-sized sludge dehydration treatment occasions. Compared with other types of dehydrators, the mud cake has a high solid content rate, a small area, and is convenient for post-processing such as transportation.
