When larger sundries pass through the slitting shaft 54, the slitting shaft 54 cannot slit the sundries and cannot crush the sundries, so that the sundries push the slitting shaft 54 to move transversely. The floating spring 551 is compressed by the slitting shaft 54, and the slitting shaft 54 returns to the original position by the floating spring 551 when the sundries pass through the slitting shaft 54.

In another embodiment, as shown in fig. 15, the waste heat recovery mechanism 90 includes: a delivery pump 91, a medium delivery pipe 93 and a medium return pipe 94; an inlet of the medium conveying pipe 93 and an outlet of the medium return pipe 94 are respectively connected to the heat pump system 30, and the conveying pump 91 is disposed in the medium return pipe 94, so that the medium circulates in the pipe to take away heat of the flue gas entering the chimney Y.
The specific working principle is as follows:
when the sludge is dried, the sludge mass or the sludge block is firstly subjected to slitting treatment through the primary slitter 50, so that the surface area of the sludge is increased, and the sludge is conveniently and quickly dried. The sludge after the primary slitting enters the blank conveying mechanism 60 and is conveyed to the secondary slitting machine 70, and most of the sludge after the primary slitting can be adhered together due to the fact that the sludge after the primary slitting contains a large amount of moisture and needs to be separated through the secondary slitting.
The mud strips after the secondary slitting are conveyed on the blank conveying mechanism 60, and at the moment, the heat pump system 30 continuously provides energy for the drying box 20, so that the mud strips on the blank conveying mechanism 60 are dried.
In the two slitting processes, if the sundries floating spring 551 is compressed, the distance between the driving shaft 542 and the floating shaft 543 is increased, sundries can pass through the space conveniently, and the floating spring 551 resets after the sundries pass through the space, so that the slitting shaft 54 is restored to the initial position. The foreign matters are prevented from influencing or damaging the cutting shaft 54.
If the treated sludge can be used as a building raw material, the sludge can be discharged into a rotary kiln for treatment, smoke with heat generated in the treatment process of the rotary kiln is discharged through a chimney Y, and the heat in the smoke can be recycled by arranging a waste heat recovery device before the discharge, so that the effect of saving energy is achieved. If the flue gas is directly discharged into the heat pump system 30 through the exhaust fan 92, the flue gas with heat is discharged after being processed by the heat pump system 30. Or the heat of the flue gas entering the chimney Y is taken away through medium circulation.
When the equipment runs for a period of time, the equipment needs to be overhauled and maintained, and because the volume problems of the drying box 20 and the heat pump system 30 need to use external equipment to lift one of the components away, then the overhaul personnel can overhaul the equipment, and the equipment needs to be restored through the external equipment after overhaul, so that the problems of time and labor waste exist. Therefore, the adjusting device 40 is arranged between the drying box 20 and the heat pump system 30, the adjusting device 40 can enable a maintenance channel 80 to be formed between the drying box 20 and the heat pump system 30, and a maintenance person can perform maintenance on the drying box 20 and the heat pump system 30 through the maintenance channel 80. The increase of external devices and the increase of cost are avoided.
The specific operation flow is as follows: the heat pump system 30 is pushed out towards one end far away from the drying box 20 through a hydraulic cylinder or an air cylinder, so that an overhaul channel 80 for an overhaul worker to enter is formed between the drying box 20 and the heat pump system 30, the overhaul worker can overhaul and maintain the drying box 20 and the heat pump system 30 through the cylinder, and the overhaul difficulty on one side, close to the drying box 20 and the heat pump system 30, of the drying box 20 is avoided.
One of the screw rods 421 is driven to rotate by the rotation of the driving motor 423, and the screw rods 421 drive the screw nuts 422 arranged on the screw rods 421 to perform linear movement, so that an overhaul channel 80 for an overhaul person to enter is formed between the drying box 20 and the heat pump system 30.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
