Description

Technical Field

[0001] The utility model relates to the technical field of sludge drying, and more specifically, to a rotary sludge drying device. Background Art

[0002] Sludge is a high-water-density substance between liquid and solid, mainly composed of organic matter, produced during the biological treatment of sewage. It has strong hydrophilicity. In the sludge treatment process, it is usually necessary to use a sludge dryer to dry it.

[0003] Among them, the patent application number CN202321783900.9 discloses a drum-type sludge drying device. It includes a base, a drum dryer, a heat preservation layer, a heater and a feed nozzle, etc. The upper part of the base is rotatably connected to the drum dryer, the base is connected to the heat preservation layer, the heat preservation layer is located outside the drum dryer, the upper side of the heat preservation layer is connected to the heater, and the right side of the drum dryer is connected to the feed nozzle;

[0004] When this structure is in use, the rotating plate is connected to contact the trigger column, which drives the opening and closing plate to rotate, so that the feeding nozzle is opened, and then the coagulant is added to the feeding nozzle, thereby achieving the effect of adding flocculant and sludge to the drum dryer at the same time, and controlling the amount of flocculant according to the amount of sludge. However, this structure is not easy to throw out more water in the sludge when in use, resulting in low drying efficiency. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a rotary sludge drying device, aiming to solve the problems raised in the above-mentioned background technology.

[0006] The utility model provides the following technical solution: a rotary sludge drying device comprises a drying cylinder, wherein a drying assembly is arranged in the drying cylinder;

[0007] The drying assembly comprises a drying liner arranged in a drying cylinder, a plurality of drainage holes for drainage are provided on the outer side of the drying liner, an extension cylinder is arranged at one end of the drying liner, and the extension cylinder extends to the end of the drying cylinder;

[0008] A movable cover is sleeved on the outer side of the extension cylinder, and the movable cover is movably connected to the drying cylinder through a hinge. A hot air box for drying is arranged at one end of the movable cover, and two handles are arranged on the movable cover.

[0009] It can be seen that in the above technical solution, the sludge is added to the drying liner and drained through the drain hole. At the same time, the hot air box gathers the heated airflow through the extension tube and then transports it to the drying liner. When the drying liner rotates, the sludge can also be diffused in the drying liner through the centrifugal force generated by the rotation of the drying liner, which makes it easy for the hot and warm airflow to fully contact the sludge, thereby improving the sludge drying efficiency and effect.

[0010] Optionally, in a possible embodiment, a focusing groove is provided at the bottom of the inner cavity of the drying cylinder, the focusing groove is arranged obliquely downward, a drainage port for drainage is provided at the bottom of the focusing groove, a driving motor is provided on one side of the top of the drying cylinder, a turntable is provided at one end of the drying cylinder, the turntable passes through the drying cylinder through a rotating shaft and is fixedly connected to a drying liner, the driving motor is connected to the turntable through a belt drive, a tray is provided at one end of the drying liner, the tray is installed in the drying cylinder, a plurality of cleaning rods are provided on the outside of the tray, a plurality of the cleaning rods extend to the outside of the drying liner and contact the drying liner, and the vertical cross-sectional shape of the cleaning rod is set to be L-shaped;

[0011] It can be seen that in the above technical solution, the driving belt is started by the driving motor to drive the turntable and the drying liner to rotate, so that the water in the sludge can be drained out. The water drained from the sludge is gathered by the collecting trough and then discharged through the drain port. In addition, the arrangement of the tray and the cleaning rod not only ensures the stability of the drying liner during rotation, but also the cleaning rod can scrape off the impurities adhering to the outside of the drying liner to avoid impurities clogging the drain holes.

[0012] Technical effects and advantages of the utility model:

[0013] By setting up a drying component, compared with the prior art, the overall design is simple and the structure is reasonable. Through the corresponding coordinated use of various structures, the sludge is added to the drying lining and drained through the drain holes. At the same time, the driving motor starts the driving belt to drive the turntable and the drying lining to rotate, thereby draining the water in the sludge.

[0014] The hot air box gathers the heated airflow through the extension cylinder and then transports it to the drying liner. When the drying liner rotates, the sludge can also be diffused in the drying liner through the centrifugal force generated by the rotation of the drying liner, which makes it easy for the hot and warm airflow to fully contact the sludge, thereby improving the sludge drying efficiency and effect.
