[0014] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0015] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0016] The utility model provides a multi-unit combined tubular continuous flip ventilation device, comprising a frame 1, on which a plurality of sealed tube assemblies 2 are installed, the plurality of sealed tube assemblies 2 are distributed up and down, and the adjacent sealed tube assemblies 2 are connected, the outer wall of the sealed tube assembly 2 is installed with a constant temperature tube assembly 3, the top of the sealed tube assembly 2 is installed with a feed inlet 201, the right side of the feed inlet 201 and an exhaust port 202 is installed on the sealed tube assembly 2, one side of the frame 1 is installed with an air preheater 5, and the bottom of the sealed tube assembly 2 is installed with a constant temperature tube assembly 3, and the top of the sealed tube assembly 2 is installed with a feed inlet 201, and the right side of the feed inlet 201 and the exhaust port 202 is installed on the sealed tube assembly 2. An air inlet 501 is installed on the side wall, the air preheater 5 is connected to the air inlet 501 through a pipe 502, a discharge port 203 is installed at the bottom of the sealing tube assembly 2, a reduction motor 4 is evenly distributed on the frame 1, a stirring blade 401 is penetrated through the sealing tube assembly 2, and the reduction motor 4 is connected to the stirring blade 401 through a rotor 402, and a star-shaped discharger 204 is installed on the feed port 201 and the discharge port; the feed port 201 and the discharge port are started and stopped by the star-shaped discharger 204;

[0017] like Figure 1-2As shown, when the multi-unit combined tubular continuous turning ventilation device is actually used, before the materials to be processed in the sludge treatment process enter the multi-unit combined tubular continuous turning ventilation drying device, the reduction motor 4 drives the rotor 402 to cooperate with the main shaft assembly to start, and the ventilation system is started, that is, the air preheater 5 cooperates with the pipeline 502 to transport hot air to the air inlet 501. The constant temperature pipe assembly 3 is composed of a water jacket and a thermal insulation layer. Since both the water jacket and the thermal insulation layer are conventional components, they are not marked in the figure. The main shaft assembly drives the stirring blade 401 to rotate in the multi-layer working layer in the constant temperature combined pipe; the constant temperature combined pipe (the air in the combined pipe formed by the sealing pipe assembly and the constant temperature pipe assembly 3) is discharged from the exhaust air duct, and a slightly negative pressure space is formed in the device shell. After the air enters from the bottom air inlet duct, it is blown into the shell of the multi-layer working layer device by forming a vortex wind through the stirring blade structure to form a circulation. The material enters quantitatively and evenly from the feed port 201 at the top of the multi-unit combined tubular continuous tumbling ventilation drying device. The outer edge of the stirring blade 401 lifts the material evenly and slowly, so that the contact area between the material particles and the constant temperature tube wall and the slightly warm air in the tube is increased, and the thermal efficiency reaches the optimal state. When the main shaft assembly (the combination formed by the stirring blade 401 and the rotor 402) rotates and the blade pushes the material to the air inlet 501, the slightly warm air in the tube blows the material at the air inlet 501 to form a quantitative boiling state and dry the material. At the same time, part of the material falls and is pushed to the working position. The lower main shaft assembly operates in reverse to form a new cycle. After the material processing is completed, it is quantitatively discharged from the star-shaped discharger 204 at the bottom of the device shell and enters the next process. A constant temperature component is installed on the outer wall of the multiple groups of sealed tube assemblies 2 to insulate the outer wall of the sealed tube assembly 2, and then the reducer drives the main shaft assembly to drive the material in the sealed tube assembly 2 to stir, and then cooperates with the air preheater 5 to deliver hot air to the sealed tube to complete the drying of the sealed tube assembly 2. Compared with conventional drying and ventilation machines that occupy a large area and consume a lot of energy, the technical solution adopted by the utility model enables the material to be fully dried in the sealed tube assembly 2, reduces energy consumption, has a compact overall structure, is easy for staff to install and maintain, and reduces later maintenance costs.

[0018] Working principle: before the materials to be processed in the sludge treatment process enter the multi-unit combined tubular continuous turning ventilation drying device, the reduction motor drives the rotor to start with the main shaft assembly, and the ventilation system starts, that is, the air preheater cooperates with the pipeline to deliver hot air to the air inlet position, and the main shaft assembly drives the stirring blades to rotate in the multi-layer working layers in the constant temperature combined tube; the constant temperature combined tube (the air in the combined tube formed by the sealing tube assembly and the constant temperature tube assembly) is discharged from the exhaust air duct, and a slightly negative pressure space is formed in the device shell. After the external air enters from the bottom air inlet duct, it is blown into the multi-layer working layer device shell through the stirring blade structure to form a vortex wind, forming a circulation. The material enters quantitatively and evenly from the feed port on the top of the multi-unit combined tubular continuous turning ventilation drying device, and the outer edge of the stirring blade lifts the material evenly and slowly, so that the contact area between the material particles and the constant temperature tube wall and the slightly warm air in the tube is increased, and the thermal efficiency reaches the best state.
