Internal inlet orifice plate grille-Fornitore globale

No. 88 Zhaozhuang Road, Yangmiao Town, Hanjiang District, Yangzhou City (Yangzhou Environmental Protection Technology Industrial Park)

Product Introduction

The NJKB series orifice plate grid cleaning machine is a new type of fine grid solid-liquid separation equipment developed by Boyi Environmental Protection Technology Co., Ltd. to better meet the needs of industries such as municipal sewage treatment, industrial wastewater treatment, and tap water interception.

In general, different mechanical grilles can achieve different interception efficiencies for different sewage treatment processes,The NJKB series perforated plate fine grid can continuously and efficiently intercept solid debris of various shapes in water, especially flat, long strip, and fiber shaped slag that is difficult to intercept with conventional grids. It can greatly reduce the load on subsequent processes, improve the efficiency of subsequent equipment, and reduce the number of equipment maintenance times.

Product advantages

① The filtration area is large and the flow rate is high. The sewage passes through the filter orifice plate from both sides and the bottom at once, with a large interception area and low head loss.

② High interception efficiency: The orifice plate adopts circular hole designs with different aperture sizes, and sealing designs are used at various docking and matching parts to ensure the highest interception efficiency for different filtration accuracies;

③ Smooth operation and low operating costs: The mesh belt chain is designed to be maintenance free, and multiple protection devices are installed in the electronic control system. The power configuration adopts precise calculation and type testing to ensure the optimal operational economy of the equipment

Ordering Notice (Backup)

matters needing attention:

1The contract shall specify the width, depth, and filtration accuracy of the channel. When the height of the slag outlet is not specified, the equipment shall be supplied according to the standard product height;

2When special requirements are not specified in the contract, supply according to the equipment standard technical parameters;

3The contract should specify the equipment control method and whether it needs to be interlocked with the slag conveying equipment. Otherwise, on-site control of this equipment will be provided according to company standards;

4Generally, two or more devices share a set of slag chute, high drainage press, backwash pump, and pipeline. If each device needs to be separately equipped with a high drainage press, water pump, or other requirements, please specify in advance;

5The first party shall provide a backwash water source: filtered reclaimed water or tap water, if there is a certain pressure water source on site（5barIf the above), the equipment does not need a backwash water pump, otherwise it needs to be pressurized with a water pump;

6The first party shall set up drainage ditches near the high drainage press to divert the water from the press.
