Description

Technical Field

[0001] The present application relates to the technical field of stirring structures, and particularly to a stirring blade for carbonized sludge that is convenient to clean. Background Art

[0002] Carbonizing sludge can convert pollutants into available resources. However, during the sludge carbonization process, the sludge gradually solidifies and cakes, easily adhering to the inner wall of the tank and the stirring structure, and is not convenient to clean. Summary of the Invention

[0003] The purpose of the present application is to provide a stirring blade for carbonized sludge that is more convenient to clean.

[0004] To achieve the above purpose, the present application provides a stirring blade for carbonized sludge that is convenient to clean: including an axial rod, the axial rod is fixedly connected with a spiral scraping and stirring plate through a plurality of transverse stirring rods, the outer diameter of the spiral scraping and stirring plate is constant, and longitudinal stirring rods are fixedly connected between layers of the spiral scraping and stirring plate, which can apply a force to the caked material on the inner wall of the carbonization tank.

[0005] As a preference, each of the transverse stirring rods is collinear and perpendicular to the axis of the axial rod, and the transverse stirring rods are fixedly connected to the lower surface of the spiral scraping and stirring plate. Compared with the upper surface of the spiral scraping and stirring plate, the probability of contacting the sludge is lower.

[0006] As a preference, these transverse stirring rods are arranged at equal intervals along the same extension direction as the spiral scraping and stirring plate, providing a uniform supporting force for the spiral scraping and stirring plate.

[0007] As a preference, the included angle between adjacent transverse stirring rods in the horizontal projection plane is a right angle, which is more suitable for the square axial rod.

[0008] As a preference, the lower end of the axial rod has a restraint ring, the outer side surface of the restraint ring is fixedly connected with a cantilever, and the end of the cantilever extends upward and is fixedly connected with the lower end of the longitudinal stirring rod, improving the bending resistance of the longitudinal stirring rod.

[0009] As a preference, the axial rod is hollow, and a transmission ring is fixedly connected to the upper end of the axial rod for connecting with a driving mechanism through a coupling.

[0010] As a preference, the longitudinal stirring rod is parallel to the axial rod, the longitudinal stirring rod is close to the outer side of the spiral scraping and stirring plate, and the side surface of the longitudinal stirring rod is flush with the outer side surface of the spiral scraping and stirring plate, and can simultaneously contact the caked carbonized sludge in the carbonization tank.

[0011] As an optimization, the lower end of the spiral scraping and stirring plate is provided with a bottom flat scraping plate, and the upper end of the spiral scraping and stirring plate is provided with a top flat scraping plate. The planes where the bottom flat scraping plate and the top flat scraping plate are located are both perpendicular to the axis of the axial center rod, and are used for scraping the carbonized sludge on the inner top surface and the inner bottom surface of the carbonization tank.

[0012] Compared with the prior art, the beneficial effects of the present application are as follows:

[0013] (1) By using the framework composed of the transverse stirring rod and the longitudinal stirring rod to fix the spiral scraping and stirring plate, the outer side surface of the spiral scraping and stirring plate is very close to the inner wall of the carbonization tank at both the upper end and the lower end, and the caked carbonized sludge can be effectively peeled off, thereby reducing the accumulation of dirt inside the carbonization tank and reducing the subsequent cleaning difficulty;

[0014] (2) By arranging the transverse stirring rod below the spiral scraping and stirring plate, the connection part between the transverse stirring rod and the spiral scraping and stirring plate is made to contact the sludge as little as possible. Even though the entire stirring structure is relatively complex, the dirt accumulated in the difficult-to-clean parts is less, and the cleaning difficulty of the sludge stirring blade itself is also lower.

[0021] Next, in combination with the specific embodiments, the present application will be further described. It should be noted that, on the premise of not conflicting, any combination can be formed between the following-described embodiments or technical features.

[0022] In the description of the present application, it should be noted that for orientation terms, such as the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., which indicate the orientation and positional relationship are based on the orientation or positional relationship shown in the drawings. This is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of the present application.

[0023] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects and do not necessarily have to be used to describe a specific order or sequence.

[0024] The terms "comprising" and "having" and any variations thereof in the description and claims of the present application are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or are inherent to these processes, methods, products or devices.

[0025] As Figures 1-5 shown, the carbonized sludge stirring blade facilitating cleaning includes a hollow central shaft 1. Generally, the central shaft 1 is cylindrical, or can also be a quadrangular prism. The central shaft 1 is fixedly connected with a spiral scraping plate 5 through a number of transverse stirring rods 2. Each transverse stirring rod 2 is collinear with the axis of the central shaft 1 and perpendicular to it. Since the central shaft 1 is vertical, the transverse stirring rods 2 are horizontal. The transverse stirring rods 2 are fixedly connected to the lower surface of the spiral scraping plate 5. Under the shielding effect of the spiral scraping plate 5, the probability of the position where the transverse stirring rods 2 are connected to the spiral scraping plate 5 contacting the carbonized sludge is lower, and it is not easy to accumulate dirt. These transverse stirring rods 2 are arranged at equal intervals along the extension direction consistent with the spiral scraping plate 5, that is to say, the transverse stirring rods 2 also rotate and rise along the spiral direction while rotating. The included angle between adjacent transverse stirring rods 2 in the horizontal projection plane is a right angle, and one circle of the spiral scraping plate 5 will be connected to four transverse stirring rods 2.

[0026] The outer diameter of the spiral scraping and stirring plate 5 is constant, and the pitch is usually also set to be constant. The longitudinal section of the spiral scraping and stirring plate 5 is rectangular. The outer side surface of the spiral scraping and stirring plate 5 is usually very close to the inner wall of the carbonization tank. The longitudinal stirring rods 4 are fixedly connected between the layers of the spiral scraping and stirring plate 5 to keep the distance between the layers of the spiral scraping and stirring plate 5 stable. The longitudinal stirring rods 4 are parallel to the central axis rod 1 and, together with the transverse stirring rods 2, serve as the skeleton structure of the spiral scraping and stirring plate 5. The longitudinal stirring rods 4 are close to the outer side of the spiral scraping and stirring plate 5 and can assist the spiral scraping and stirring plate 5 in scraping the carbonized sludge on the inner wall of the carbonization tank. The lower end of the spiral scraping and stirring plate 5 has a bottom flat scraping plate 501, which is very close to the inner bottom surface of the carbonization tank. The upper end of the spiral scraping and stirring plate 5 has a top flat scraping plate 502, which is very close to the inner top surface of the carbonization tank. The planes where the bottom flat scraping plate 501 and the top flat scraping plate 502 are located are both perpendicular to the axis of the central axis rod 1, and are used to scrape up the carbonized sludge on the inner bottom surface and the inner top surface of the carbonization tank and mix it with other non-adherent carbonized sludge.

[0027] The lower end of the central axis rod 1 has a restraint ring 102, which is used to cooperate with the bearing structure at the bottom of the carbonization tank to form a rotating pair, ensuring the stability of the lower end of the central axis rod 1. The outer side surface of the restraint ring 102 is fixedly connected with a cantilever 3, and the end of the cantilever 3 extends upward to be fixedly connected with the lower end of the longitudinal stirring rod 4 that crosses over the spiral scraping and stirring plate 5. Moreover, the upper end of the longitudinal stirring rod 4 that crosses over the spiral scraping and stirring plate 5 will also be fixedly connected with the end of the transverse stirring rod 2. In this way, both the upper and lower ends of the longitudinal stirring rod 4 are constrained, having a higher bending resistance. The upper end of the central axis rod 1 is fixedly connected with a transmission ring 101, which is used to connect with the output end of the driving mechanism.

[0028] Working principle: The transverse stirring rods 2 and the longitudinal stirring rods 4, as the skeleton structure of the spiral scraping and stirring plate 5, can apply a horizontal force to the carbonized sludge, while the inclined upward spiral scraping and stirring plate 5 can apply an upward component force to the carbonized sludge. Moreover, the outer side surface, the upper and lower ends of the spiral scraping and stirring plate 5, and the longitudinal stirring rods 4 are very close to the inner wall of the carbonization tank, and can scrape the carbonized sludge on the inner wall of the carbonization tank, effectively reducing the accumulation of dirt in the carbonization tank and facilitating the subsequent cleaning of the carbonization tank.

[0029] The above describes the basic principle, main features, and advantages of the present application. Those skilled in the art of this industry should understand that the present application is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present application. Without departing from the spirit and scope of the present application, the present application will have various changes and improvements, and these changes and improvements all fall within the scope of the present application claimed.
