Wastewater Fine Screening Machine for Food Sewage Primary Treatment

BOEEP wastewater fine screening machine is a primary sewage treatment equipment, which is often used in food wastewater treatment process.
  • XQ 1.5
  • XQ

Product Introduction

BOEEP wastewater fine screening machine for sewage filtration is one of the important dirt blocked equipment in the wastewater treatment. It can be applied for municipal sewage, drainage pumping plant, urban wastewater, industry wastwater and so on.

Structure and Working Principle

BOEEP wastewater fine screening machine for sewage filtration is composed of transmission device, rake chain system, supporting frame and screening removal mechanism.

The rake made of nylon or stainless steel are fixed on the chain shaft according to a certain arrangement, circulating toothed harrow surface. The whole rakes surface does the circulating exercise from top to bottom driven by the driven chain. The solid suspended matter intercepted on the toothed harrow will be picked up to the discharge port and be cleared away by turning the brush. Then the goal of protecting the water pump and reducing subsequent work load will be reached.

Technical Features

  1. Tooth surface shall have convex strips; ensure that it is not easy for deformation by strength.

  2. Main machine frame is integrated type and the structure is secure and reasonable.

  3. This device can act accurately and it can effectively prevent damage caused by over-loading to motor reduction box.

  4. Dirt can be totally removed and the operation is flexible and reliable.

  5. Electrical overloading protection device adopts hot relay when faults occurs on the machinery or over-loading is available, it will automatically stop and gives an alarm.  Actions of this device are sensitive and reliable.

  6. Chain and chain track form closed state, which can effectively prevent screenings falling into the track and to avoid jamming.

  7. This machine adopts fully-automatic control. It can still works even if there is no one keeping it. In case of any jamming, it will give an alarm and automatically stop.

Technical Parameters

Note: This mechanical rotary fine bar screen is a kind of customized product. The specific technical parameters are different from customers' need. The following parameters are used only as reference.

Model: XQ1.5×customize size Screen type: Fine screen
Channel width (mm): 1500 Channel depth (mm): customize
Machine net width (mm): 1400 Grid gap (mm): 1-15
Flow rate through the screen (m/s):  as below Installation angle: α=75°
Outlet height (mm): 750 Motor power (kw): N=1.5
Motor Protect level/ insulation level: IP55/ F Working time: 24 hours/day continuous run or interval run


1-Theoretical water flow (exclude sediment etc.) =average velocity of the flow across the gate × water  flowing area× the effective rate of water flowing area.

2-The designed water flow rate V= 1m/s corrresponding to the water level difference is approximately as △H=200MM.

3-The actual water flow should be based on the gate slag and water etc. Usually, it is generally estimated at 0.5 times the theoretical value.
