Description

Technical Field

[0001] The utility model relates to the technical field of sludge dehydration devices, in particular to a non-powered sludge dehydration device. Background Art

[0002] Generally, large and medium-sized sewage treatment plants are equipped with fixed mechanical sludge dewatering equipment rooms, while it is not very appropriate for small sewage treatment plants to be equipped with fixed mechanical sludge dewatering equipment rooms. Most small sewage treatment plants are currently equipped with mobile sludge dewatering equipment. The existing mobile sludge dewatering equipment mostly uses small mechanical dewatering equipment placed on a mobile vehicle. The equipment needs to be equipped with a mobile power supply, which has high energy consumption. This will increase the operating cost of the equipment and will also cause a certain burden on the environment. It also requires manual care to ensure the normal operation of the equipment, which will increase labor costs and increase operational risks and safety hazards. On the one hand, this mobile dewatering equipment is only suitable for sewage operating units that jointly manage multiple sewage stations, and is not suitable for a single small sewage treatment plant. On the other hand, the mobile vehicle needs to travel between the stations, which increases the transportation cost. Therefore, it is very necessary to design a low-cost, unpowered sludge dewatering device. Utility Model Content

[0003] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a non-powered sludge dehydration device. After the sludge enters the drying box, most of the sewage is filtered out by the filter screen, and then the heat-absorbing cloth is used to absorb the heat energy of the sun to increase the temperature inside the drying box. This can accelerate the evaporation and dehydration process of the water in the sludge. Moreover, due to the non-powered design, the sludge drying process can be carried out without the need for additional electricity or heat source supply, thereby saving energy. In addition, the operation process is relatively simple and does not require complicated operation and maintenance. The heat-absorbing cloth can be automatically covered on the top of the drying box or put away through the cloth collecting device and the cloth releasing device. No human intervention is required, which saves human resources and operation time. Automated operation can improve work efficiency and reduce the possibility of human errors and operational errors.
