It is a hydrophilic substance with a colloidal structure. Before sludge incineration, it is necessary to remove as much water as possible to facilitate better incineration. Currently, the main methods of drying are high temperature and extrusion.

[0004] The sludge in the environmentally friendly new energy sludge dryer disclosed in the above patent document is dehydrated while being stirred. Although the contact area of ​​the sludge is increased during dehydration, the sludge is sticky together, making it difficult for heat to enter the interior, so a longer high-temperature operation time is required, and the sludge dehydration rate is still relatively low. Summary of the invention

[0005] In view of the above problems existing in the prior art, the present invention provides a sludge incineration and drying device. The technical problem to be solved by the present invention is: how to increase the speed of sludge dewatering.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] A sludge incineration and drying equipment comprises a machine body; characterized in that a transverse mesh plate and a sludge squeezing frame located directly above the mesh plate and movable in the length direction of the mesh plate are fixed on the machine body, the sludge squeezing frame has a plurality of parallelogram holes for sludge to be embedded and is connected with a telescopic member capable of deforming the plurality of parallelogram holes, and the machine body is provided with a feeding pipe for introducing sludge into the sludge squeezing frame, a pressurizing component capable of quickly draining the sludge on the sludge squeezing frame, a heating component for drying the drained sludge in the sludge squeezing frame, and a discharging component capable of draining the dried sludge in the sludge squeezing frame in sequence in the length direction of the mesh plate.

[0008] Its working principle is as follows: the equipment in this technical solution is equipped with four stations: sludge feeding station, sludge squeezing station, sludge drying station and sludge unloading station. The feeding pipe is located at the sludge feeding station, and the sludge is introduced from the feeding pipe to the sludge squeezing rack. Then the sludge squeezing rack moves along the length direction of the mesh plate to the sludge squeezing station. The pressurizing component is located at the sludge squeezing station. The pressurizing component pressurizes the sludge on the sludge squeezing rack to squeeze the sludge into several parallelogram holes. The telescopic parts work to deform several parallelogram holes, so that the water in the sludge is squeezed out. In this process, the sludge is squeezed out. The sludge is divided into several small portions, and then the sludge extrusion rack moves to the sludge drying station along the length direction of the mesh plate. The heating component is located at the sludge drying station. Since the sludge is divided into several small portions, the sludge has a mesh-like gap, which is convenient for the heating component to evenly transfer heat to all parts of the sludge on the sludge extrusion rack, so that the sludge is heated evenly, thereby improving the sludge dewatering speed. After that, the sludge extrusion rack continues to move along the length direction of the mesh plate to the sludge unloading station. The unloading component located at the sludge unloading station can discharge the sludge in the parallelogram holes on the sludge extrusion rack, so as to collect the treated sludge.

[0009] In the above-mentioned sludge incineration and drying equipment, the sludge squeezing frame includes a plurality of mutually parallel plate bodies 1 and a plurality of mutually parallel plate bodies 2, the plate bodies 1 and the plate bodies 2 are of the same length, each of the parallelogram holes is formed by two of the plate bodies 1 and the two plate bodies 2, and the two plate bodies 1 on the parallelogram hole are hinged to the two plate bodies 2 through a hinge axis, two guide rails 1 extending along the length of the mesh plate are provided above the mesh plate, the two guide rails 1 are arranged in parallel and spaced apart, and a slide groove 1 along the length direction thereof is opened on the opposite side, the sludge squeezing frame is located between the two guide rails 1, and a slider 1 which can be embedded in the corresponding slide groove 1 is connected to the hinge axis near the two guide rails 1 on both sides of the sludge squeezing frame; the number of the telescopic members is two, and the telescopic rods of the two telescopic members are respectively connected to the two guide rails 1 and can make the two guide rails 1 approach or move away from each other when working simultaneously.
