Abstract
Description
Technical Field
[0001] The present application relates to the technical field of sludge treatment, and in particular to a sludge dryer. Background Art
[0002] Sludge drying is the process of drying sludge through drying equipment to evaporate its moisture, thereby reducing the volume and weight of the sludge and facilitating transportation and treatment. The dried sludge can be used in soil improvement, fuel preparation, building materials production, etc. Sludge drying technology is widely used in the field of environmental protection and can effectively reduce the cost of sludge treatment and its impact on the environment.
[0003] When the traditional sludge dryer is in use, an elastic rubber fixed by an aluminum alloy bracket is provided at the rear end of the lower mesh belt.

[0041] The following is combined with Figure 1-3 This application is described in further detail.
[0042] The embodiment of the present application discloses a sludge drying machine.
[0043] Reference Figure 1 and Figure 2 A sludge drying machine includes a machine body 1, a drying element 2 and a sludge scraping assembly 3. A feed port 11 is provided at one end of the machine body 1, and a discharge port 12 is provided at the other end. A driving roller 13 and a driven roller 14 are rotatably connected in the machine body 1. A driving element 15 is coaxially connected to the driving roller 13. A drying mesh belt 16 is sleeved on the driving roller 13 and the driven roller 14. The drying mesh belt 16 is used to transport the material from the feed port 11 to the discharge port 12. The drying element 2 is installed on the machine body 1. The sludge scraper assembly 3 includes a fixing frame 31, an abutment member 32 and an elastic member 33. The fixing frame 31 is fixedly connected to the machine body 1 and is located below the lower drying mesh belt 16. The abutment member 32 is slidably connected to the fixing frame 31. The elastic member 33 is installed between the fixing frame 31 and the abutment member 32 to drive the abutment member 32 to abut against the drying mesh belt 16, so that after the abutment member 32 is worn at the top, it can still be driven by the elastic member 33 and abut against the drying mesh belt 16, thereby ensuring that the abutment member 32 can continue to effectively block the sludge.
[0044] In this embodiment, the feed port 11 is located on the upper side of the machine body 1, and the discharge port 12 is located on the lower side of the machine body 1. A feed hopper 4 is also provided on the upper side of the machine body 1, and the feed hopper 4 is connected to the feed port 11. The cross-sectional area of the feed hopper 4 gradually increases as it moves away from the feed port 11. The setting of the feed hopper 4 facilitates pouring the sludge into the machine body 1 through the feed port 11.
[0045] The drying element 2 can be heated by electric heating or heat pump heating. In this embodiment, electric heating is used, and the drying element 2 is located at the top of the casing, so that the temperature on the upper side of the casing is higher, which makes it easier for the sludge to enter the casing and be dried quickly.
[0046] In this embodiment, the driving member 15 is installed on the outside of the machine body 1, and the driving member 15 is a driving motor.
[0047] The body 1 is rotatably connected to the discharge port 12 with a blocking block 5, which is made of magnetic material. In this embodiment, the blocking block 5 is made of metal iron, and other embodiments may also use a magnetic block or other metal that can be adsorbed by the magnetic block. A magnetic block is provided at the corresponding position of the body 1 and the blocking block 5, and the magnetic block and the blocking block 5 are magnetically attracted to each other to block the discharge port 12. The setting of the blocking block 5 facilitates sealing the bottom of the body 1 and reduces the heat loss inside the body 1.
[0048] In an optional embodiment, a handle 51 is provided on a side of the blocking block 5 away from the machine body 1, and the handle 51 is away from the rotating end of the blocking block 5. The setting of the handle 51 facilitates opening the blocking block 5.
[0049] The machine body 1 is provided with a monitoring module 6, which is located at the discharge port 12. The monitoring module 6 detects the amount of sludge accumulated at the discharge port 12, and the time to open the blocking block 5 can be determined. When the monitoring module 6 detects that there is a lot of sludge accumulated at the discharge port 12, the blocking block 5 can be opened to discharge the dried sludge in the casing.
[0050] The abutment member 32 in this embodiment is tilted, and the tilting direction of the abutment member 32 is opposite to the moving direction of the drying mesh belt 16 at the abutment point. The tilting arrangement enables the abutment member 32 to bear force better and to scrape off the adhered sludge on the drying mesh belt 16 better.
[0051] Reference Figure 3 The abutment member 32 includes a mounting platform 321 and a brush plate 322. The mounting platform 321 is mounted on an elastic member 33. The elastic member 33 in this embodiment is a spring. A plurality of elastic members 33 are evenly arranged between the fixing frame 31 and the mounting platform 321. The evenly arranged plurality of elastic members 33 make the force on the mounting platform 321 more stable and uniform.
[0052] Due to the wear of the brush plate 322 caused by long-term use, a mounting groove 323 is opened on the side of the mounting platform 321 away from the elastic member 33, and the brush plate 322 is inserted into the mounting groove 323. The setting of the mounting groove 323 facilitates the replacement of the brush plate 322 with a new one after the brush plate 322 is severely worn, thereby ensuring that the brush plate 322 can have a good blocking effect.
[0053] The fixing frame 31 is provided with a plurality of limiting posts 324. In this embodiment, two limiting posts 324 are provided. The two limiting posts 324 are located at both ends of the fixing frame 31. Two limiting holes 325 are provided on the mounting platform 321. The limiting posts 324 are inserted into the limiting holes 325 one by one. By the cooperation between the limiting posts 324 and the limiting holes 325, the elastic member 33 can stably drive the mounting platform 321 to move toward the drying mesh belt 16.
[0054] In an optional implementation, a plurality of driving rollers 13 and driven rollers 14 are provided, and the drying mesh belt 16 is sleeved on the driving roller 13 and the driven roller 14 located at the same horizontal position. The moving directions of adjacent drying mesh belts 16 are opposite, and the drying mesh belt 16 located at the bottom extends toward the moving direction of the upper layer of the drying mesh belt 16 located at the top to receive the material on the drying mesh belt 16 above.
[0055] By using the arrangement of a plurality of driving rollers 13 , driven rollers 14 and drying mesh belts 16 , the path and time of the sludge in the machine body 1 are prolonged, so that the drying effect of the sludge in the machine body 1 is better.
[0056] In this embodiment, the lengths of adjacent drying mesh belts 16 are the same. In other embodiments, the length of the lower drying mesh belt 16 can be set to be longer than that of the upper mesh belt, and can also serve to receive the sludge transmitted by the upper mesh belt.
[0057] The adjacent drying mesh belts 16 in this embodiment are staggered in the vertical direction along the length direction. By staggering the adjacent drying mesh belts 16 of the same length, the machine body 1 can be arranged in a rectangular shape, which is convenient for placing the machine body 1 and can effectively utilize the space inside the machine body 1.
[0058] In an optional embodiment, a plurality of receiving rollers 7 are arranged between the driving roller 13 and the driven roller 14 at the same horizontal position, and the top of the receiving roller 7 abuts against the bottom of the upper drying mesh belt 16. The receiving rollers 7 are used to share the gravity of the drying mesh belt 16 receiving the sludge, so that the drying mesh belt 16 is not easily deformed when receiving the sludge during operation.
[0059] The implementation principle of a sludge dryer in an embodiment of the present application is as follows: by adopting the above-mentioned technical solution, the sludge is poured from the feed port 11 to the upper surface of the drying mesh belt 16 using the feed hopper 4, and the driving member 15 is started. The drying mesh belt 16 is driven to move by the driving roller 13 and the driven roller 14, so that the sludge on the upper surface is transported layer by layer to the discharge port 12.
[0060] During the conveying process of the drying mesh belt 16, after the upper layer of the drying mesh belt 16 receives the sludge and rotates to the lower end, the elastic member 33 on the fixed frame 31 drives the mounting platform 321 to move toward the drying mesh belt 16 under the limit of the limit column 324, so that the brush plate 322 abuts against the surface of the lower layer of the drying mesh belt 16, thereby cleaning the sludge carried on the lower mesh belt.
[0061] At the same time, since the elastic member 33 continuously drives the abutment member 32 to move toward the drying mesh belt 16, after the abutment member 32 is worn at the top, it can still be driven by the elastic member 33 to press the remaining part against the drying mesh belt 16, thereby ensuring that the abutment member 32 can continue to effectively block the sludge.
[0062] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
