Description

A sludge dewatering device

technical field

The utility model belongs to the technical field of sludge treatment, in particular to a sludge dewatering device.

Background technique

At present, the existing technologies commonly used in the industry are as follows:

The existing sludge mechanical dehydration method is to add polymer coagulant to pretreat the sludge, and then filter to process the sludge. The filter is to filter the sludge with a filter layer, and the dewatered sludge is left on the filter layer. , The sludge is filtered by gravity to remove free water under the action of gravity, and then the sludge is dehydrated by squeezing and shearing the sludge through a wedge press.

Sewage treatment (wastewater treatment): The process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people.

After sludge dehydration, microorganisms and bacteria are difficult to grow, will not pollute the environment, and are convenient for storage and transportation. The dehydrated sludge can also be used as fertilizer, so sludge dehydration is very important.

In summary, the problems in the prior art are:

In the prior art, the contact area between the filter plate and the sludge is small, the dehydration effect on the sludge is poor, and it is not suitable for high-efficiency sludge dehydration treatment.

The position of the lid of the sludge bucket cannot be controlled by the positive and negative motor to squeeze the sludge, so that the lid of the sludge bucket cannot be lifted to take out and utilize the dehydrated sludge.

In the prior art, it is impossible to accurately weigh the mass of sludge dehydrated, and it is impossible to calculate the moisture content of the sludge in the sludge tank, which results in the inability to inhibit the growth of microorganisms and bacteria, causing pollution to the environment, and the sludge after dehydration Cannot be used as fertilizer.

The negative pressure in the water storage device cannot be monitored. Since the water storage device is connected to the sludge tank, the negative pressure in the water storage device is equal to the negative pressure in the sludge tank. Only when the negative pressure reaches a certain value can the sludge tank maintain a certain level. Only when the vacuum degree is high, the vacuum pump will efficiently pump out the water in the sludge bucket.

The existing technology cannot monitor the stress applied to the barrel lid, and the stress applied to the barrel lid can be obtained by combining the negative pressure value of the barrel to obtain the relationship between the two, and the stress value for maintaining the negative pressure in the barrel cannot be calculated.

The significance of solving the above technical problems:

The dehydration efficiency of the sludge is very important. The shape of the filter plate of the utility model is wheel-shaped, and the contact area with the sludge is large, which can improve the dehydration treatment efficiency of the sludge.

The position of the lid of the sludge bucket is controlled by the forward and reverse motor, which can not only exert stress on the sludge to squeeze the sludge, but also lift the position of the lid to take out and utilize the dehydrated sludge.

By weighing the quality of the water storage device, the mass of the sludge dehydrated can be obtained, so as to calculate the water content of the sludge in the bucket, and clarify the next step of treatment or utilization of the sludge in the bucket.

Monitoring the negative pressure in the sludge tank can tell the tightness of the whole device. Only when the negative pressure reaches and maintains a certain value, can a certain degree of vacuum be maintained in the sludge tank, and the vacuum pump will reduce the moisture in the sludge tank to a high level. Efficiency draws.

Monitoring the stress applied to the barrel cover can combine the negative pressure value of the barrel to obtain the relationship between the two, so as to know the stress value to maintain the negative pressure in the barrel.
