Supporting Equipment for Sludge Treatment Supplier: Dosing, Conveying and Storage Under One Roof
Qingben Environmental Technology (Jiangsu) Co., Ltd. designs and manufactures the supporting equipment that makes a sludge dewatering room operate as one system. As a professional Supporting Equipment for Sludge Treatment Supplier based in Yangzhou, China, we supply automatic polymer preparation skids, compact manual dosing units, shaftless screw conveyors and storage hoppers that connect dewatering machines to truck loading.
These units are built to the same mechanical standard as the screw presses, belt presses and low-temperature dryers we produce. Each one is sized to the plant’s hydraulic and solids load, and each can be wired into the dewatering line’s control logic before dispatch.
Four Machines, One Process Logic
Conditioning chemistry starts before mechanical dewatering: polymer is dissolved to a controlled concentration and injected into the sludge stream. After dewatering, the cake moves by conveyor to a hopper for storage and loading. Dosing accuracy determines polymer consumption and final cake dry solids; conveying and storage design determines whether the room stays clean and whether the line can run with minimal manual attendance.

Integrated Dosing Device
Our Integrated Dosing Device combines dry powder feeding, dissolution, maturation, metering and dosing on a single skid. The dry dosing machine and heating design reduce caking, while the dosing amount and water inlet volume can be adjusted to prepare the required liquid concentration. A low powder level triggers an alarm signal.
- Optional vacuum loader and online dilution system
- Tank material options: stainless steel 304, polypropylene PP, fiberglass FRP
- Maturation time: one hour
- Fully automatic operation from powder feeding to dosing

Manual Dosing Device
The Manual Dosing Device is built for plants with low chemical demand, intermittent operation or trained staff already present. The barrel, dosing pump, electric control box and pipe fittings are integrated onto one frame, which simplifies installation and transport. It is easy to refill manually, and the transparent level area lets operators confirm chemical use in real time.
- Models: QBJY1000, QBJY2000, QBJY3000
- Mixing power: 0.75–1.5 kW
- Tank options: stainless steel SS304 or SS316L, polyethylene PE, fiberglass FRP
- Dosing port DN25, water port DN25, evacuation port DN32 or DN40 depending on model
Screw Conveyor
After sludge dewatering equipment is installed, the Screw Conveyor moves the dewatered cake to the loading location. The shaftless conveyor is normally made in a sealed structure to collect the material and improve the working environment. It consists of a U-shaped trough, feed hopper, cover plate, spiral body, liner and drive mechanism. Fully automatic electrical protection can realize joint control with the sludge dewatering system, and the trough is lined with wear-resistant material to reduce noise. Spiral blades are available in stainless steel or manganese steel.

The feed hopper length, angle and overall conveying length are customized to match the dewatering machine discharge and the loading bay position. Standard installation angle is ≤20°; angles between 20° and 30° can be ordered specially.
Sludge Hopper for Storage and Batch Discharge
The sludge hopper is the final collection point in the dewatering room. It receives dewatered cake from the conveyor, stores it until a sufficient quantity accumulates, and then discharges through two bottom doors into a truck. The sector doors are controlled by a cylinder or an electric push rod, so the operation can be manual, pneumatic or integrated into the line control system.
We size the hopper live volume and discharge height to the customer’s truck access and haulage interval, and we match the door actuator to the available compressed air or electrical supply.
Controls and Automation Integration
Supporting equipment should not add parallel manual work in an already busy dewatering room. Our dosing devices and conveyors are supplied with fully automatic electrical protection and can be set for joint control with the sludge dewatering system. When the plant uses Modbus-based communication, the dosing unit, conveyor and hopper doors can exchange signals for coordinated operation.
- Low powder level alarm on the integrated dosing device
- Conveyor interlock with screw press, belt press or dryer operation
- Hopper door control by cylinder or electric push rod
- Control voltage and frequency configured for the destination country
Quality Assurance, Installation and Project Support
Our manufacturing system is covered by ISO9001, ISO14001, ISO45001 and CE marking. We provide comprehensive technical support from project consultation and design through installation, commissioning, trial operation and operator training. After-sales maintenance, troubleshooting and equipment upgrade services keep the supporting line running with the rest of the plant.
When we ship a complete system, the dosing device, conveyor and hopper are prepared together with the dewatering equipment so the mechanical interfaces, control signals and installation sequence match on site.
Information We Use to Configure Your Solution
To prepare a proposal and functional layout, we use the project data below. The more precise the operating point, the better we can match model, tank material, motor power and control interface.
- Daily cake output, dewatering equipment type and planned operating hours
- Polymer type, normal dosage, required solution concentration and dosing point
- Conveying distance, incline angle, discharge height and required capacity
- Desired hopper live volume, truck size and loading height
- Electrical supply voltage/frequency and control protocol such as Modbus
- Available footprint, clearances and existing support steelwork
Frequently Asked Questions
What supporting equipment do you manufacture for sludge treatment?
We manufacture integrated dosing devices, manual dosing devices, screw conveyors and sludge hoppers. Together they cover chemical conditioning, cake transfer, storage and truck loading around the dewatering machine.
Which dosing device should a small plant choose?
For low, intermittent dosing with staff present, the manual QBJY1000–3000 units are a compact and economical choice. For continuous operation or unattended rooms, the automatic QBYTH 500–4000 L/h integrated dosing device is the correct fit.
Can the screw conveyor be linked to the dewatering machine?
Yes. Fully automatic electrical protection allows joint control with the sludge dewatering system, so the conveyor starts and stops according to cake discharge without separate manual operation.
What tank materials are available for dosing devices?
The integrated dosing device can be supplied with stainless steel 304, polypropylene PP or fiberglass FRP. Manual dosing devices add SS316L and polyethylene PE options.
How is the sludge hopper discharged?
The hopper has two sector doors at the bottom, controlled by a cylinder or an electric push rod. When the selected cake volume has accumulated, the doors open and unload the cake into a truck.
Do you support installation and commissioning?
We provide system integration, installation guidance, commissioning, trial operation and operator training. Our project support continues with after-sales maintenance, troubleshooting and equipment upgrades.
