Description

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0026] like Figure 1-4 As shown, the sludge drying device of the sludge treatment equipment proposed in this utility model includes a drying box 1, and a feeding mechanism including a feeder 21 installed on the upper part of the drying box 1. The feeder 21 has a through structure and an upper knife table 25 and a lower knife table 26 are symmetrically installed on the upper and lower parts.

[0027] The transmission mechanism includes a transmission platform 31 arranged in layers on the upper part of the drying box 1. A drive motor 32 is installed on one side of the transmission platform 31. A transmission roller 33 that passes through the transmission platform 31 is installed at the output end of the drive motor 32. A transmission belt 34 is sleeved on the outside of the transmission roller 33.

[0028] A drain platform 4 is provided below the conveyor belt 34. The lower part of the drain platform 4 is an inclined structure, and a water storage cavity is left at the intersection. The wastewater dripping during the drying process is collected and gathered through the drain platform 4.

[0029] The drying mechanism includes a heating platform 51 installed on the outside of the drain platform 4. The heating platform 51 has a built-in heating coil 52 with a "serpentine" structure and a heat-conducting plate 53 installed on the outside. The other end of the heat-conducting plate 53 is connected to an air supply device 54. The end face of the air supply device 54 facing the drain platform 4 is equipped with a ventilation grille 55.

[0030] In this embodiment, before entering the drying chamber 1, the sludge is initially sheared by the upper cutter 25 and lower cutter 26 in the feeder 21, so that the sludge enters the conveying mechanism in a separated state. The conveying mechanism has three sets of conveying platforms 31, which are stacked on the upper part of the drying chamber 1. The discharge end of the lower conveying platform 31 is close to the discharge end seat 6 that penetrates the outer wall of the drying chamber 1. By setting them in layers, the conveying path of the sludge drying process is increased in a limited space, and the conveying process is still heated by a single drying mechanism, reducing energy waste.

[0031] In an optional embodiment, the conveyor belt 34 is a hollow structure with sieve holes on its surface, and the mesh size of the sieve holes of the three sets of conveyor belts 34 increases layer by layer. The sludge is filtered through the conveyor belt 34, which serves two purposes: firstly, to allow the sludge to fall into the water, and secondly, to transport the sludge from top to bottom, quickly conveying the small-particle-size sludge that meets the requirements to the lower layer.

[0032] As an example of sludge shearing: A cylinder 22 is provided on one side of the feeder 21. A movable piston rod 23 is installed at the output end of the cylinder 22. The other end of the piston rod 23 is connected to the upper blade table 25 through the connecting plate 24. At this time, the upper blade table 25 is a movable structure that moves synchronously with the piston rod 23 and the connecting plate 24. The lower blade table 26 is a fixed structure. A transmission gap is left between the two. During the movement of the upper blade table 25, the sludge can be repeatedly sheared to assist in the separation of sludge and solve the problem of sludge entering the drying box 1 in an adhesive state.

[0033] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
