[0037] Next, for the pretreatment of sludge drainage, specifically, the drainage component 200 includes a first electric actuator 210, the output end of which is fixedly connected to a pressure plate 220 by bolts. The pressure plate 220 presses down on the sludge, discharging some of the internal water from the sludge. The output end of a second electric actuator 230 is fixedly connected to a push plate 240 by bolts, facilitating the pushing of the pressed sludge to the conveying trough 290. The bottom of the push plate 240 is in close contact with a first filter plate 250.

The side wall of the first filter plate 250 is fixedly connected to a conveying trough 290 by screws. Three auxiliary rollers 280 are inserted inside the conveying trough 290 to facilitate the sludge to slide down the conveying trough 290. The conveying trough 290 is close to the auxiliary rollers 280 and can scrape off the sludge on the surface of the auxiliary rollers 280, thus cleaning the surface of the auxiliary rollers 280. The top side wall of the conveying trough 290 is fixedly connected to multiple baffles 291 by screws to guide the sludge to slide down and prevent the sludge from sliding out of the conveying trough 290.

[0038] Meanwhile, in order to recover energy from the waste gas, specifically, the recovery component 300 includes a collection tank 310, which is made of metal. The top of the collection tank 310 is fixedly connected to an exhaust pipe 320 by bolts. The exhaust pipe 320 is also made of metal. Inside the exhaust pipe 320, a filter plate 331 is inserted. The surface of the filter plate 331 is coated with activated carbon to purify the waste gas and block impurities floating in the waste gas. Inside the exhaust pipe 320, a baffle plate 330 is inserted to block and collect excess moisture in the waste gas. The bottom of the baffle plate 330 is fixedly connected to a water storage tank 350 by bolts to facilitate the storage and collection of wastewater collected by the baffle plate 330. Inside the exhaust pipe 320, an exhaust fan 340 is fixedly connected by screws to assist in the circulation of hot air.

[0039] Furthermore, to facilitate the maintenance of the air intake and drainage components 200 of the drying device, specifically, an air intake 174 is provided on the side wall of the outer frame 170 to provide airflow for the air intake fan 141, and a cabinet door 172 is connected to the side wall of the outer frame 170 by a hinge, so that users can collect the sewage inside the water storage tank 270 or repair the drainage components 200.

[0040] It is worth noting that, for the stability of the drainage assembly 200, specifically, the side walls of the first filter plate 250 and the second filter plate 260 are fixedly connected to the outer frame 170 by screws, and a pusher is welded to the bottom of the side wall of the pusher plate 240 to facilitate the scraping of residual sludge on the surface of the first filter plate 250, so that the pusher plate 240 achieves the effect of cleaning the surface of the first filter plate 250. The output end of the conveying trough 290 extends into the inside of the mixing tank 110 to facilitate the discharge of sludge after drainage into the mixing tank 110.

[0041] Finally, in order to recover waste gas and wastewater, specifically, the collection tank 310 is closely attached to the output end of the mixing tank 110 to facilitate the entry of waste gas into the exhaust pipe 320. The collection tank 310 can also intercept the sludge flying out of the mixing tank 110, reducing environmental hygiene problems around the drying device. The bottom of the water storage tank 350 is welded with a drain pipe to facilitate the collection and discharge of wastewater inside the water storage tank 350. The output end of the exhaust pipe 320 leads to the inside of the mixing tank 110 to achieve hot air circulation.

[0042] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0043] The device or equipment models mentioned in this article may be as follows:

[0044] First motor 140: D180MO250030CE;

[0045] Second motor 150: Y160M-R3;

[0046] First electric linear actuator 210: HB-DJ809;

[0047] Second electric actuator 230: HB-DJ809.

[0048] Combination Figures 1-5 The sludge treatment and drying device of this embodiment is used in the following specific process:

[0049] 1: Sludge is fed into the drying device through the feed inlet 175 opened on the side wall of the outer frame 170, and then the first motor 140, the second motor 150, the first electric push rod 210 and the second electric push rod 230 inside the drying device are controlled through the control panel 173 connected to the side wall of the outer frame 170.

[0050] 2: The sludge first enters the drainage component 200 for pre-treatment and falls onto the first filter plate 250 through the feed inlet 175. Then, the first electric push rod 210 pushes the pressure plate 220 to press down the sludge and discharge some of the water inside the sludge. The discharged wastewater falls through the first filter plate 250 to the second filter plate 260. The second filter plate 260 retains the sludge and impurities inside the wastewater. The wastewater then flows into the water storage tank 270 at the bottom of the second filter plate 260. After that, the second electric push rod 230 pushes the push plate 240 to push the sludge onto the conveying trough 290. The pusher at the bottom of the push plate 240 also removes the residual sludge attached to the surface of the first filter plate 250. Then, the sludge is discharged into the mixing tank 110 through the conveying trough 290.

[0051] 3. After the sludge enters the mixing tank 110, the first motor 140 drives the air intake fan 141 to operate. The air intake fan 141 blows air into the mixing tank 110 through the air intake port 174. The airflow becomes hot air after passing through the heater 130. The mixing blades 113 inside the mixing tank 110 will also break up and mix the sludge with the hot airflow. Then, the excess hot exhaust gas will enter the collection tank 310 through the output end of the mixing tank 110, and then enter the exhaust pipe 320 at the top of the collection tank 310. Then, the hot exhaust gas will be filtered by the air filter plate 331, and then the water baffle plate 330 will block the water vapor inside the hot exhaust gas. Finally, it will be discharged back into the mixing tank 110 through the output end of the exhaust pipe 320, forming a heat cycle and reducing energy consumption. At the same time, the water trapped by the water baffle plate 330 will flow into the water storage tank 350 below to collect water resources. Then, the dried sludge will be discharged into the storage tank 180 through the discharge port 171.

[0052] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way.
