[0020] The technical solutions of the present invention will be described clearly and completely below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present invention, not all embodiments.

[0021] Reference Figures 1 to 4 A novel high-water-content municipal sludge drying and reduction auxiliary processor of the present invention includes: a drying rotating component 100 and a drying air supply component 200.

[0022] like Figure 3 and Figure 4 As shown, the drying rotation assembly 100 includes a drying shell 110, a drying barrel 120 rotatably arranged in the drying shell 110, and a rotating drive mechanism 130 for driving the drying barrel 120 to rotate around its own axis. The barrel wall of the drying barrel 120 of this embodiment is distributed with a plurality of through holes 121, and the axis of the drying barrel 120 is arranged at an angle to the vertical direction. Specifically, the axis of the drying barrel 120 of this embodiment extends in the horizontal direction, and a barrel mouth 122 is provided at one end of the drying barrel 120, and the drying shell 110 is provided with a mud discharge port 111 located at the bottom and an opening 112 opposite to the barrel mouth 122.

[0023] It can be understood that the barrel wall of the drying barrel 120 is a filter structure, which separates large particles of sludge from micro particles of sludge. Finally, the large particles of sludge remain in the drying barrel 120, while the micro particles of sludge enter the drying shell 110 through the through hole 121 and avoid clogging of the mud discharge port 111.

[0024] The opening 112 is provided with a sealing plate 113 , which has an open state and a closed state. When the sealing plate 113 is in the open state, the sludge to be dried is added into the drying barrel 120 through the opening 112 .

[0025] The drying air supply assembly 200 includes an air supply cooling module, which is used to provide drying cold air to the drying barrel 120 , and the air outlet end of the air supply cooling module is connected to the drying barrel 120 .

[0026] During use, the sealing plate 113 is opened, and the sludge to be dried is added into the drying barrel 120 from the barrel mouth 122, and then the sealing plate 113 is closed. The drying barrel 120 is driven to rotate around its own axis by the rotary drive mechanism 130 to drive the sludge to be centrifugally flipped in the drying barrel 120. At the same time, the air supply module provides drying cold air to the drying barrel 120. Under the rotation and flipping of the sludge, the inside and outside of the sludge can be dried at the same time, thereby improving the drying effect of the sludge.

[0027] Among them, the rotation drive mechanism 130 includes a drive motor 131, a driving pulley 132 connected to the output shaft of the drive motor 131, a driven pulley 133 coaxially fixedly connected to the drying barrel 120, and a belt 134 connected between the driving pulley 132 and the driven pulley 133. In this embodiment, the driving motor 131 drives the driving pulley 132 to rotate, and the driving pulley 132 drives the driven pulley 133 to rotate through the belt 134, thereby driving the drying barrel 120 to rotate.

[0028] In other embodiments, the rotation drive mechanism 130 may adopt other drive structures.

[0029] The drying air supply assembly 200 of this embodiment also includes an air supply hose 210 connected to the air supply cooling module. The sealing plate 113 is provided with an air inlet 114 connected to the barrel mouth 122. The end of the air supply hose 210 away from the air supply cooling module is connected to the air inlet 114, so that the air supply hose 210 can move with the sealing plate 113 without interfering with the rotation of the drying barrel 120.

[0030] The air supply cooling module of this embodiment includes a blower 220 and a cooling air box 230 connected in sequence. The interior of the cooling air box 230 is a hollow structure and is provided with a condenser 231. After the blower 220 is started, the temperature of the air is reduced to a predetermined temperature range through the cooling effect of the condenser 231, and then enters the drying barrel 120 to achieve sludge drying.

[0031] Furthermore, a mud discharge trough 115 is provided at the bottom of the drying shell 110 in an inclined manner. A mud discharge port 111 is located at the bottom end of the mud discharge trough 115 . The dried sludge moves downward along the mud discharge trough 115 and is discharged from the mud discharge port 111 .

[0032] At the same time, a collecting funnel 300 is provided below the mud discharge port 111 , and the collecting funnel 300 is used to collect the dried sludge.

[0033] In some embodiments, a chassis 700 is also included, and a drying shell 110 and an air supply cooling module are installed in the chassis 700. The mud discharge port 111 and the air inlet end of the air supply cooling module are both connected to the inner cavity of the chassis 700 to form a circulating air duct. After the dried air is discharged from the mud discharge port 111, it flows back to the air supply cooling module through the inner cavity of the chassis 700 and is reused.

[0034] In some embodiments, a cleaning assembly is also included, which includes a cleaning water pump 400 and a cleaning nozzle 410 that are interconnected. The cleaning nozzle 410 extends into the drying barrel 120 from the opening 112 and the barrel mouth 122. The cleaning nozzle 410 of this embodiment is installed on the sealing plate 113. After the drying process is completed, the interior of the drying barrel 120 can be cleaned by the cleaning nozzle 410.

[0035] A universal pulley assembly 500 is installed at the bottom of the chassis 700 to enable the entire device to move.

[0036] A plurality of height-adjustable legs 600 are installed at the bottom of the chassis 700 .

[0037] In some embodiments, a PLC controller is also included to control the operation of the entire device.

[0038] In summary, the present invention drives the driving motor 131 to rotate the active pulley 132, which in turn drives the driven pulley 133 via the belt 134, thereby driving the drying barrel 120 to rotate. A through port is provided at one end of the drying barrel 120, which is in relative communication with the air inlet 114. The blower 220 provides air volume, and the condenser 231 cools the air, thereby drying the sludge. Sludge collected from municipal projects is fed into the through port of the drying barrel 120, thereby activating the blower 220 and condenser 231, and low-temperature gas is introduced through the air supply hose 210. The driving motor 131 then drives the drying barrel 120 to rotate, utilizing the air volume and the rotational motion of the drying barrel 120 to improve the drying effect of the municipal sludge.
