Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1:

[0028] like Figures 1-4 As shown, a rotary drum de-drying machine feeding sealing mechanism includes a frame 1, on which a rotary drum de-drying machine main shaft 2 with adjustable ends is mounted. One end of the rotary drum de-drying machine main shaft 2 is connected to a rotation drive source. The feeding end of the rotary drum de-drying machine main shaft has a hollow structure. The middle of the rotary drum de-drying machine main shaft is designed with a discharge port with a hollow structure. A rotary sealing joint assembly 3 is connected to the hollow end of the rotary drum de-drying machine main shaft. The rotary sealing joint assembly 3 includes a rotary connector 4 and a sealing gasket 5. The sealing gasket 5 is installed at the end of the rotary drum de-drying machine main shaft. The rotary connector is installed on the frame and presses the outer side of the sealing gasket.

[0029] The rotary connector 4 has a first connecting flange 6 installed on one inner end, and a second connecting flange 7 is installed on the main shaft of the drum de-dryer at the corresponding sealing gasket mounting position. The sealing gasket 5 is sandwiched between the first connecting flange 6 and the second connecting flange 7. The arrangement of the first and second connecting flanges provides a stable clamping environment for the sealing gasket. This flange connection method not only enhances the connection strength between the sealing gasket and the rotary connector and the main shaft of the drum de-dryer, but also ensures the flatness and tightness of the sealing surface, thereby further improving the sealing effect.

[0030] The inside end of the rotary joint is provided with a reduced diameter section 8, the diameter of which decreases linearly along the material flow direction, and the discharge end of the reduced diameter section is inserted into the main shaft of the drum flour separator. The above structure design has the following advantages: (1) Optimizing the material flow path: the design of the reduced diameter section allows the material to pass through a gradually narrowing channel before entering the main shaft of the drum flour separator. This design helps to reduce vortex and turbulence during material flow, making the material flow more smoothly into the drum, thereby improving the efficiency of screening and flour removal. (2) Improving the durability of the sealing element: the design of the reduced diameter section inserted into the main shaft of the drum flour separator makes the contact area between the rotary joint and the main shaft more uniform, reducing the wear of the sealing element caused by excessive local pressure. At the same time, the linearly decreasing design of the reduced diameter section also plays a certain buffering role, further prolonging the service life of the sealing element. In addition, by adjusting the clamping force between the first and second connecting flanges and the size of the reduced diameter section, different material characteristics and processing requirements can be adapted. This design makes the inlet sealing mechanism widely applicable to drum flour separators of various specifications and models, improving the adaptability and flexibility of the equipment.

[0031] The first and second baffles are respectively connected to the hollow section and the solid section, and the material enters the area between the first and second baffles from the feed port of the hollow section. The above structure design can optimize the material processing flow: by installing the first and second baffles on the main shaft of the drum flour separator corresponding to the discharge port position, and designing the main shaft of the drum flour separator as a solid section and a hollow section with a feed port, the material can enter the area between the first and second baffles from the feed port of the hollow section for flour removal treatment. This design not only optimizes the material processing flow, but also improves the flour removal efficiency and material utilization rate.

[0032] The first and second baffles are respectively connected to the hollow section and the solid section, and the material enters the area between the first and second baffles from the feed port of the hollow section. The above structure design can improve the uniformity and efficiency of flour removal: the multiple material falling partitions connected between the first and second baffles are installed circumferentially around the main shaft of the drum flour separator, forming a material falling port together with the first and second baffles. This design allows the material to be more evenly distributed and flowed in the drum, thereby improving the uniformity and efficiency of flour removal. At the same time, the setting of the material falling partitions can also prevent excessive accumulation or blockage of the material in the drum, ensuring the stable operation of the equipment.

[0033] The reinforcing rib plates 15 are installed on the outer side walls of the first baffle 11 and the second baffle 12 at the positions connected with the main shaft of the cylinder de-flaking machine, and a plurality of reinforcing rib plates 15 are evenly distributed around the main shaft of the cylinder de-flaking machine. The above structure design can enhance the structural strength and stability: the reinforcing rib plates installed on the outer side walls of the first baffle and the second baffle at the positions connected with the main shaft of the cylinder de-flaking machine are evenly distributed around the main shaft of the cylinder de-flaking machine. This design not only enhances the connection strength between the first baffle, the second baffle and the main shaft of the cylinder de-flaking machine, but also improves the structural stability and carrying capacity of the entire equipment. When running for a long time or processing a large amount of materials, this design can ensure the stability and safety of the equipment. In addition, the above structure design also prolongs the service life of the equipment: the introduction of the reinforcing rib plate and the setting of the material falling partition plate not only improve the structural strength and stability of the equipment, but also reduce the impact and wear of the material on the equipment. This design not only prolongs the service life of the equipment, but also reduces the maintenance cost and replacement frequency, bringing higher economic benefits to enterprises.

[0034] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application. Any reference signs in the claims should not be regarded as limiting the claims involved.
