[0002] Sludge is a byproduct of wastewater treatment. However, sludge contains a lot of harmful substances and cannot be used directly. Most of the time, sludge needs to be dewatered and then dried. This can effectively reduce the water content of the sludge, thereby reducing its volume and making it easier to carry out harmless treatment or repurpose it.

[0003] When sludge undergoes drying treatment, although it has been dehydrated, its moisture content is still relatively high. When it is piled up during drying, uneven drying is likely to occur. Utility Model Content

When the sludge is on the drying plate, it will gradually move downward under the vibration of the vibrating motor.

Based on the embodiments in this application, other similar embodiments obtained by those skilled in the art without creative effort should all fall within the scope of protection of this application. Furthermore, directional terms mentioned in the following embodiments, such as "up," "down," "left," and "right," are only for reference to the directions in the accompanying drawings; therefore, the directional terms used are for illustrative purposes and not for limiting the invention.

[0030] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0031] Example: A sludge drying device, see attached document. Figure 1 -Appendix Figure 5The system includes a drying box 1 and a drying mechanism 2. The top of the drying box 1 is fixedly connected to a feed pipe 11, and the bottom is fixedly connected to a discharge pipe 12. Multiple drying mechanisms 2 are arranged vertically within the drying box 1. Each drying mechanism 2 includes a drying plate 21, elastic plates 22, elastic elements 28, an air inlet pipe 29, and a vibration motor. The drying plate 21 is hollow internally, with its feed end inclined upwards. The width of the drying plate 21 is horizontal, and it has several air outlet holes 211 extending upwards through it. Multiple elastic plates 22 are arranged on the drying plate 21 along its inclined direction. The length of each elastic plate 22 is... The direction is parallel to the width direction of the drying plate 21. The cross-section of the elastic plate 22, which is perpendicular to its own length direction, is arc-shaped. One end of the arc-shaped elastic plate 22 is fixedly connected to the drying plate 21, and the other end extends toward the discharge end of the drying plate 21. The elastic element 28 is set at the bottom of the drying plate 21 to support the drying plate 21. The air inlet pipe 29 is used to input hot air into the drying plate 21. The vibration motor is fixedly connected to the bottom of the drying plate 21. The feeding end of the uppermost drying plate 21 is located below the feeding pipe 11, and the discharge end of the lowermost drying plate 21 is located above the discharge pipe 12. Among two adjacent drying plates 21, the discharge end of the upper drying plate 21 is located above the feeding end of the lower drying plate 21.

[0032] The sludge enters the feed end of the uppermost drying plate 21 through the feed pipe 11, and then passes through multiple drying plates 21 one by one until it is discharged from the discharge end of the lowermost drying plate 21 and discharged through the discharge pipe 12. When the sludge is on the drying plate 21, it gradually moves downward under the vibration of the vibrating motor, and during the downward movement, it is repeatedly vibrated upward and falls onto the elastic plate 22, thereby dispersing the sludge through impact and making the sludge dry more evenly. The air outlet 211 is set on the side of the drying plate 21 where the elastic plate 22 is located, so that when the sludge falls and is dispersed by impact, hot air can pass through the gaps in the sludge, improving the efficiency and uniformity of sludge drying.

[0033] Specifically, there are several sets of air outlets 211. Multiple sets of air outlets 211 are arranged along the inclined direction of the drying plate 21, and multiple air outlets 211 in the same set are arranged along the width direction of the drying plate 21. Each set of air outlets 211 corresponds to an elastic plate 22. The connection between a set of air outlets 211 and the corresponding elastic plate 22 is close to the side of the discharge end of the drying plate 21.

[0034] By setting the position of the air outlet 211, the air outlet 211 can be blocked by the elastic plate 22, making it difficult for sludge to enter the air outlet 211.

[0035] Specifically, the drying mechanism 2 also includes a support plate 25, a guide tube 26, and a sliding rod 27. Each drying mechanism 2 includes two support plates 25, which are respectively located below the drying plate 21 near the lower inclined end and near the upper inclined end of the drying plate 21. The two ends of the support plates 25 are fixedly connected to each other. Two guide tubes 26 are fixedly connected to the top of each support plate 25 near the two ends of the support plate 25. The axis of the guide tubes 26 is vertically set. Each guide tube 26 corresponds to a sliding rod 27. The sliding rod 27 is inserted into the corresponding guide tube from top to bottom and can slide up and down in the guide tube 26. Each drying mechanism 2 includes four elastic elements 28, which are respectively located in the four guide tubes 26. One end of the elastic element 28 contacts the support plate 25, and the other end contacts the bottom of the sliding rod 27.

[0036] Specifically, the elastic element 28 is set as a spring.

[0037] Specifically, the drying board 21 has two side plates 23 on both sides, and the two side plates 23 are vertically arranged and their length direction is along the inclined direction of the drying board 21.

[0038] The side plate 23 prevents sludge from falling from both sides of the drying plate 21.

[0039] Specifically, two guide plates 24 are fixedly connected to one end of the top side of the drying plate 21 near the lower inclined end of the drying plate 21. The ends of the two guide plates 24 that are far apart from each other are fixedly connected to the two side plates 23. The ends of the two guide plates 24 that are close to each other are inclined towards the lower inclined end of the drying plate 21.

[0040] The two guide plates 24 can concentrate the sludge that has been moved to the lower end of the drying plate 21 and place it near the middle of the width direction, so that the sludge is less likely to fall off the sides of the drying plate 21 when it falls onto the next drying plate 21.

[0041] Specifically, the air intake pipe 29 is fixedly connected to one side of the drying plate 21 near the inclined lower end.

[0042] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
