Sand washing dewatering and recycling integrated machine

The sand washing and recycling integrated machine integrate water washing and fine sand dewatering and recycling, so it is also called sand washing and recycling integrated machine, fine sand recycling and dewatering integrated machine, and mud and sand washing and separating equipment. This machine cleverly connects the fine sand recovery machine with the sand washing machine, with a reasonable structure, a small area, and a lower investment cost than the two equipment.

1. Function introduction

The sand washing and recycling integrated machine is mainly divided into the sand washing part and the fine sand recovery part; the sand washing part has the same function as the general wheel sand washing machine and is used for water washing, dewatering, and desliming. The recycling parts can be combined according to customer needs. If fine sand recycling is required, it can be connected to a general fine sand recycling system. If fine sand dewatering and recycling are required, it can be connected to a dewatering fine sand recycling machine. If different sand production effects are required, they can also be configured. Layer dewatering screen.

2. Working principle

1) Structure composition

It is composed of a high-pressure separator, dewatering screen, impeller separator, reducer, vacuum high-pressure pump, cleaning tank, high-position return tank, motor, vibration motor, and other components.

2) Workflow

The sand-water mixture enters the cleaning box, is separated by the impeller separator, and then enters the lower dewatering screen for dehydration treatment. The wastewater (containing a large amount of fine sand, mud, dust, and other impurities) overflowing from the cleaning box is transported to the high-pressure separation by the vacuum high-pressure pump Then, the fine sand after centrifugal classification and concentration is discharged into the upper layer of the dewatering screen through the sedimentation nozzle, and the wastewater, mud, dust, impurities, etc. in the cleaning tank are discharged through the overflow of the high-pressure separator and discharged into the high-level return tank. Coarse sand from the finished material on the upper layer, fine sand from the finished material on the lower layer, or a mixture of coarse and fine sand (adjustable according to requirements).

3. Features and advantages

1) Combining the characteristics and advantages of a sand washing machine and fine sand recycling machine, it has the functions of washing sand and fine sand dewatering and recycling. It is cleaner than the traditional sand washing machine and has better sand and price.

2) The all-in-one machine has higher working efficiency, low energy consumption, energy-saving, and environmental protection.

3) Reasonable structure, small floor space, simple installation, and lower investment cost than the price of two pieces of equipment.

4) Long service life and low maintenance cost.

5) Special models can be tailored according to different needs.

4. Workflow

1) After the material enters the cleaning box, it rolls under the drive of the sand washing wheel to fully contact and clean with water. At the same time, the spray pipe on the upper part of the wheel sprays water to take away impurities and foreign objects with a small specific gravity in time. The following materials are sent to the back-end dewatering screen along with the tumbling of the sand washing wheel, and after being removed from excess water, they are sent to the conveyor belt from the discharge port.

2) The wastewater (containing a large amount of fine sand, mud, dust, and other impurities) overflowing from the cleaning box is transported to the cyclone by the vacuum high-pressure pump for centrifugal classification and concentration, and the fine sand is discharged into the upper layer of the dewatering screen through the sand settling nozzle for dehydration treatment, The remaining wastewater (containing mud, dust, and other impurities) will be discharged into the high-level return tank through the overflow of the cyclone.

5. Product use

The sand washing part has the same function as the general wheel sand washing machine, which is used for water washing, dewatering, and desliming; and the recovery part can be combined according to customer needs. If fine sand recovery is required, it can be connected to a general fine sand recovery system. For sand dewatering and recycling, you can connect a dewatering fine sand recycling machine.

6. How to extend product life and maintenance methods

To purchase a sand washing and recycling machine, our customer invested a lot of money. However, if you do not pay attention to maintenance, the machine will have problems like this and the service life will be greatly shortened if the machine works for a long time. This goes against the original intention of the customer to purchase the sand washing and recycling integrated machine. Every customer hopes that their equipment can be used for a longer period and create more revenue for themselves. So how can we extend the service life of the sand washing and recycling integrated machine?

1) Always check the oil level of the reducer of the sand washer recovery integrated machine, the tightness of the V-belt, the meshing degree and the smooth condition of the gears, whether the connecting fasteners are loose, and ensure that the machine is in a normal and stable operating state. The friction parts should be sufficiently smoothed, and smooth grease should be added regularly.

2) One month after adding lubricating oil to the reducer for the first time, the lubricating oil should be replaced in time. The lubricating oil should be filtered when filling. The type of lubricating oil should be higher in the south than in the north.

3) In normal use, you should cherish the sand washing and recycling integrated machine, and pay attention to the maintenance, inspection, and cleaning of the sand washing and recycling integrated machine.
