Description

Drum type sludge dryer

technical field

The utility model relates to a dryer.

Background technique

Among the waste produced in today's industry, sludge containing heavy metals, water, poisons, etc. can easily affect clean soil, groundwater, and rivers, etc. During the environmental protection treatment process of purification, the moisture contained in the sludge often leads to an increase in weight and volume, which makes it difficult for waste treatment companies to carry out subsequent recycling and purification treatment such as compression and transportation, and increases their treatment costs. Mud must be dried first to effectively reduce volume and weight.

Existing sludge dryers include oven type, conveyor belt type, low-temperature oven type, etc. Among them, the test box type dryer uses the windmill to circulate hot air to dry the sludge in the confined space, which belongs to a batch Therefore, it is only suitable for batch treatment of a small amount of sludge. If the amount of sludge is large, uneven or too much, it will make the flow of hot air poor, and cause problems such as local high temperature and uneven temperature distribution. Therefore, it is not suitable for continuous and large amount of sludge drying treatment. The structure of the conveyor belt type dryer is similar to the current incinerator. The heating source is located at the bottom of the furnace, and the hot air circulates from the bottom to the top. , discharge and other stages, so that the sludge becomes fine gravel when discharged. This design improvement does not solve the problems of uneven heating of sludge and poor thermal cycle. Another type of low-temperature oven uses batch processing as the above-mentioned oven type, only the temperature is lower (about 40 degrees), and the sludge moisture is removed by applying the principle of dehumidification. The drying efficiency of this kind of dryer is not good, and it needs to Takes quite a long time.

Looking at the advantages and disadvantages of the existing sludge dryers, if a hot gas cycle can be provided, it can quickly and evenly heat and dry the sludge inside, and can be suitable for continuous treatment of a large amount of sludge. The drying machine, for the waste disposal industry, will further make the processing operation faster and cheaper.

The cost of installing multiple dryers.

Secondly, due to the tumbling structure design of the drum device 2 of the present utility model, the sludge can be continuously fed into the tumbling drying operation, instead of using static sludge and drying as in the existing oven-type or low-temperature oven-type dryers. Batch processing, so that once the sludge drying operation is started, the drying process can continue for several days without any interruption in the middle, and only need to replace the space bag 100 to collect the dried sludge, so it is very important for the waste treatment industry As far as the utility model is concerned, the utility model is more practical and progressive when dealing with huge sludge. Also, as mentioned above, the drum device 2 of the utility model is designed with a sealed structure, and a space bag 100 can be connected to the lower port of the discharge device 5 to collect the sludge, so the sludge is not exposed at all during the drying and output process. It will not cause public nuisance to the soil and rivers near the waste disposal site, so the waste disposal site can meet the requirements of environmental protection. It should be pointed out that the technology of the present utility model lies in the structure of the drum device 2 and the cooperation relationship with other devices. And shape, etc., are not intended to limit the scope of the utility model that can be easily changed and implemented. If the drum device 2 is designed to be partly or completely covered in the base 1 (as shown in Figure 9), or the base 1 is directly selected to be provided with a heating device, so that the hot air is directly input into the drum device 21, it is all specific. Implementing a changeable structure means that all simple changes and replacements made by using the technical means of the utility model should be included in the creative spirit and patent scope of this case, and only be specified.
