Background Art
[0002] Sludge (which may also refer to viscous substances such as animal excrement and kitchen waste) is a viscous and soft substance with varying water contents, and generally needs to be dried before it can be applied again.
[0003] For the drying operation, in addition to being difficult to be dispersed and dried due to its viscosity, the sludge is also difficult to be dried because of its varying water contents.
[0004] In addition, the viscosity also causes difficult conveyance and is likely to stick to relevant conveyance devices.
[0005] In view of this, it is necessary to develop a technology that can solve the above-mentioned existing drawbacks. Content of the Utility Model
[0006] In order to solve the problems that sludge is a viscous and soft substance with varying water contents, which is not only difficult to be dried, but also difficult to be conveyed due to its viscosity and is likely to stick to relevant conveyance devices, the utility model provides a sludge dryer which has the advantages that the sludge can flow naturally downward by gravity without transmission power quite ingeniously, the double drying design has good effect, and the flow speed and drying time can be controlled by adjusting the inclination angle.
[0007] The technical solution adopted by the utility model to solve its technical problems is as follows:
[0008] A sludge dryer, comprising:
[0009] A base device having a set of pivot joints and a support part;
[0010] A drying device is arranged on the set of pivot joints and the support part and is in an inclined state. The drying device is provided with a partition wall and is divided into a first working area and a second working area. The first working area has a first inlet, a first working space and a first outlet that are sequentially and mutually communicated; the second working area has a second inlet, a second working space and a second outlet in sequence; the first working area communicates with the second outlet of the second working area through the first outlet;
[0011] A plurality of stirring devices are sequentially arranged in the first working area in the direction from the first inlet to the first outlet; each of the plurality of stirring devices includes a power structure, an auxiliary transmission structure and a stirring structure. The auxiliary transmission structure connects the power structure and the stirring structure, and then inputs power with the power structure to drive the stirring structure to perform stirring operation in the first working space; and
[0012] At least one heat supply device is provided at the second inlet for supplying heat energy into the second working space. The heat energy is transferred from the second inlet to the second working space, the second outlet and the first working area, so that at least the partition wall and the first working area can perform the drying operation.
[0013] Thereby, the first inlet is used to supply the sludge to be dried. The sludge to be dried falls from the first inlet towards the first working space due to gravity, and then flows towards the direction of the first outlet through the partition wall. During the flowing process, the sludge to be dried is sequentially stirred by the plurality of stirring structures. The stirring action not only increases the drying time of the sludge to be dried in the first working space, but also mixes the sludge to be dried with the heat energy in the first working space, improving the drying efficiency. Finally, the dried sludge is output through the first outlet.

[0043] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 , the present utility model is a sludge dryer, which includes:
[0044] A base device 10, having a set of pivoting parts 11 and a support part 12.
[0045] The drying device 20 is disposed on the set of pivot joints 11 and the support portion 12 and is in an inclined state. The drying device 20 is provided with a partition wall W and is divided into a first working area 21 and a second working area 22. The first working area 21 has a first inlet 211, a first working space 212, and a first outlet 213 that are sequentially and communicatively connected to each other. The second working area 22 sequentially has a second inlet 221, a second working space 222, and a second outlet 223; the first working area 21 communicates with the second outlet 223 of the second working area 22 through the first outlet 213.
[0046] A plurality of stirring devices 30 are sequentially arranged in the first working area 21 in the direction from the first inlet 211 to the first outlet 213. Each of the plurality of stirring devices 30 includes a power structure 31, an auxiliary transmission structure 32, and a stirring structure 33. The auxiliary transmission structure 32 connects the power structure 31 and the stirring structure 33, and further inputs power with the power structure 31 to drive the stirring structure 33 to perform a stirring operation in the first working space 212.
[0047] At least one heat supply device 40 is disposed at the second inlet 221 for supplying heat energy H (see Figure 8A , Figure 8B and Figure 8C ) into the second working space 222. The heat energy H is transferred from the second inlet 221 to the second working space 222, the second outlet 223, and the first working area 21, so as to at least enable the partition wall W and the first working area 21 (mainly the first working space 212) to perform a drying operation.
[0048] Thereby, referring to Figure 8B , the first inlet 211 is used for feeding the sludge 91 to be dried (which may also refer to sludge-like substances such as animal excrement and kitchen waste). The sludge 91 to be dried falls from the first inlet 211 to the first working space 212 due to gravity, and then flows in the direction of the first outlet 213 through the partition wall W. During the flowing process, it is sequentially stirred by the plurality of stirring structures 33 (as shown in Figure 8C and Figure 9 ). In addition to increasing the drying time of the sludge 91 to be dried in the first working space 212, the stirring action also mixes the sludge 91 to be dried with the heat energy H (as shown by the hollow arrow in Figure 9 ) in the first working space 212. At this time, the heat energy H can be hot smoke, improving the drying efficiency. Finally, the dried sludge 92 (as shown in Figure 8C ) is output through the first outlet 213.
[0049] In practice, the support portion 12 can be one of a hydraulic telescopic rod and an electric telescopic rod (the design of the relevant support portion 12 in each view is only for illustration, and is hereby stated first).
[0050] Furthermore, when the support portion 12 is a hydraulic telescopic rod, it may include a hydraulic cylinder 121 (the oil circuit, oil pump and related components are omitted and not shown, hereby stated for clarification first) and a telescopic rod 122. The hydraulic cylinder 121 is used for the support portion 12 to pivotally connect the base device 10 and the support portion 12, and is used for relative telescoping with the telescopic rod 122.
[0051] Thereby, when the telescopic rod 122 and the hydraulic cylinder 121 are telescopically relative to each other, the inclination state between the drying device 20 and the base device 10 can be adjusted.
[0052] Refer to Figure 4 , for example, it can be adjusted from the original first inclination angle θ1 to a second inclination angle θ2. The second inclination angle θ2 is smaller than the first inclination angle θ1, so that the inclination angle between the drying device 20 and the base device 10 becomes gentler, and thus the flow rate of the sludge 91 to be dried on the partition wall W can be slowed down, and the drying time can be increased virtually.
[0053] For example, assuming that the original first inclination angle θ1 is 40 degrees, the sludge 91 to be dried can flow downward on the partition wall W faster due to gravity. When adjusted to the second inclination angle θ2 of 30 degrees, the flow rate of the sludge 91 to be dried downward on the partition wall W due to gravity becomes slower due to the reduced inclination degree. Of course, the above inclination angles can be adjusted according to the situation.
[0054] The drying device 20 corresponds to the set of pivotal connection portions 11, and has a set of pivotal connection ear portions 20A. The set of pivotal connection ear portions 20A are used for the drying device 20 to connect the set of pivotal connection portions 11.
[0055] Furthermore, the drying device 20 may further include a smoke outlet 20B. The smoke outlet 20B (as Figure 8A shown) communicates with the first working space 212 for discharging the heat energy H in the first working space 212.
[0056] Regarding the stirring structure 33, it can be in the form of a main shaft 331 extending several stirring elements 332 (as Figure 7 and Figure 9 shown) or other structures with stirring functions. And Figure 6 , Figure 8A , Figure 8B and Figure 8C (and the remaining related views), the stirring structure 33 is simplified as a cylindrical object for presentation (this is only for simplified illustration, hereby stated for clarification first).
[0057] The auxiliary drive structure 32 (only shown in a simplified manner in each view) may include a gear assembly and a belt assembly (or a chain assembly). Further, it may also include a speed reduction assembly (the components of the foregoing embodiments of the auxiliary drive structure 32 are not shown in the figure and are hereby stated first). All are adjusted and matched according to actual usage requirements.
[0058] The at least one heat supply device 40 may be a structure using one of combustion gas and fuel oil (such as a gas spraying device, a fuel oil spraying device or a similar device), so that the heat energy H may include at least one of fire and hot smoke.
[0059] Regarding the drying process of this case, first, the at least one heat supply device 40 may be pre-activated, and the heat energy H generated therefrom enters from the second inlet 221 towards the second working space 222, the second outlet 223 and the first working area 21 (refer to Figure 8A , Figure 8B and Figure 8C ) for heat transfer. Then, when the sludge 91 to be dried is fed in from the first inlet 211, since the drying device 20 is in an inclined state (taking the first angle θ1 shown in Figure 4 as an example), without the need (saving) of conveying power, the sludge 91 to be dried can directly fall from the first inlet 211 to the first working space 212 by gravity, and then flow towards the first outlet 213 along the partition wall W. During the flowing process, it is sequentially stirred clockwise (taking the Figure 8B and Figure 8C angles as a reference) by the several stirring structures 33. Refer to Figure 8B , Figure 8C and Figure 9 . In this way, the sludge 91 to be dried can be stirred from the first outlet 213 in the reverse direction towards the first inlet 211, increasing the drying time of the sludge 91 to be dried in the first working space 212 (actually also dried by the partition wall W). Furthermore, during the stirring process, the heat energy H (hot smoke) in the first working space 212 can be mixed into the sludge 91 to be dried to reduce moisture and accelerate drying.
[0060] In summary, the advantages and effects of this case can be summarized as follows:
[0061] [1] It is quite ingenious that the sludge uses gravity to flow naturally downward without conveying power. In this case, the drying device is inclined on the base device, so that the sludge to be dried can fall to the first inlet of the drying device by gravity, and then flow naturally downward along the partition wall in the direction from the first working space to the first outlet without the need of conveying power during the flowing process, which is a quite ingenious design. Therefore, it is quite ingenious that the sludge uses gravity to flow naturally downward without a conveying device.
[0062] [2] The double drying design has excellent effects. In this case, firstly (the first stage), the thermal energy (which may include fire and hot smoke) is transferred through the partition wall to the first working space, and the partition wall and the first working space can be used to dry the sludge to be dried. Secondly (the second stage), in cooperation with the several stirring devices, the thermal energy (hot smoke) is mixed into the sludge to be dried, effectively reducing the water vapor contained in the sludge to be dried and accelerating the drying speed. Therefore, the double drying design has excellent effects.
[0063] [3] Adjusting the inclination angle can control the flow rate and drying time. In this case, the drying device is inclined and installed on the base device by the support part. Furthermore, through the expansion and contraction of the support part, the inclination angle of the drying device can be adjusted to become larger or smaller, respectively controlling the speed of the sludge to be dried sliding down to become faster or slower. In principle, the faster the sliding speed downwards, the shorter the drying time, and vice versa. Therefore, adjusting the inclination angle can control the flow rate and drying time.
[0064] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Any simple modifications, equivalent changes, and decorations made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
