Description

Technical Field

[0001] This utility model relates to the field of mixing device technology, specifically to a rapid premixing device used in the asphalt preparation process. Background Technology

[0002] In the asphalt production process, premixing tanks are usually used to mix and stir the asphalt raw materials and modifiers. Common premixing tanks include a tank body and a mixing mechanism. This type of premixing tank has dead zones during the mixing process. To address this, some companies add baffles to the tank cavity wall. Baffles are longitudinally extended plates that help improve the mixing effect. However, the drawback is that the baffles are directly fixed to the tank cavity wall, which is inconvenient to operate and has low assembly efficiency, and needs to be improved. Utility Model Content

[0003] To address at least one of the aforementioned technical deficiencies, this utility model provides the following technical solution:

[0004] This application discloses a rapid premixing device for asphalt preparation, including a baffle plate, a tank, and a stirring mechanism connected to the tank. The stirring mechanism stirs the material inside the tank cavity. A cover plate for sealing the tank opening is provided at the top of the tank. A fixing frame is provided on the bottom surface of the cover plate. The fixing frame extends into the tank cavity and fits against the cavity wall of the tank. The stirring mechanism extends into the cavity enclosed by the fixing frame. A baffle plate is provided on the fixing frame.

[0005] In this solution, baffles are installed on a fixed frame, and the fixed frame is fixed to the cover plate. The fixed frame and baffles can be fixed in advance, and then the fixed frame and cover plate can be fixed. Assembly can be completed directly when the cover plate is connected to the tank body. Modular molding helps to improve the assembly speed.

[0006] Furthermore, the fixing frame includes longitudinal plates and connecting plates, with the longitudinal plates connected by the connecting plates. Baffles are provided on the longitudinal plates to simplify the structure of the fixing frame and facilitate molding and assembly.

[0007] Furthermore, the longitudinal plate is provided with a groove, and one side of the baffle is embedded in the groove with an angle of 25-35° between the baffle and the inner wall of the tank. The groove-type fitting and fixing of the baffle facilitates installation.

[0008] Furthermore, the connecting plate is ring-shaped and is spaced longitudinally on the tank body, and the longitudinal plates are spaced circumferentially along the tank body.

[0009] Furthermore, the fixing frame also includes a horizontally extending fixing plate, which is connected to the connecting plate at the top and to the cover plate. The addition of the fixing plate facilitates the fixing of the cover plate.

[0010] Furthermore, a protrusion is provided on the bottom surface of the connecting plate at the bottom and a ridge is provided on the cavity wall of the tank. The protrusion is embedded in the positioning groove formed on the ridge, and the protrusion embedded in the positioning groove helps to improve the stability of the fixing frame.

[0011] Furthermore, the cover plate is provided with a feed inlet, a feed port for the modifier, and a vent, which facilitates feeding.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model improves the installation structure of the baffle plate by supporting it with a fixing frame, which helps to increase the speed of assembly. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] Example 1

[0021] like Figure 1 , Figure 2 As shown, the rapid premixing device used in the asphalt preparation process in this example includes a baffle plate 5, a tank 1, and a mixing mechanism 3. The tank 1 is in the shape of a common cylindrical body. The top of the tank 1 is open and a cover plate 2 is fixed at the opening to seal the opening. The cover plate is equipped with a feed inlet 6, a feed port 7 for modifiers, and a vent, etc., according to the conventional layout. In use, the base asphalt, rubber powder, etc. are fed into the tank cavity through the feed inlet, and the modifiers, etc. are transported into the tank cavity through the feed port.

[0022] As for the stirring mechanism, the stirring mechanism 3 is connected to the tank 1. The stirring mechanism stirs the material in the tank cavity. If the stirring mechanism 3 is driven by a drive motor 31, the drive mechanism 31 is fixed on the top surface of the cover plate 2. The output end of the drive mechanism 31 is connected to the stirring shaft 32, and the stirring shaft 32 extends into the cavity of the tank 1.

[0023] In this example, a fixing frame is added. A fixing frame 4 is installed on the bottom surface of the cover plate 2. The fixing frame 4 extends into the cavity of the tank body 1. The fixing frame 4 is cylindrical, specifically including a longitudinal plate 41 and a connecting plate 42. The connecting plate is ring-shaped. Two connecting plates 42 are arranged at intervals along the longitudinal direction of the tank body. The two connecting plates 42 are connected by multiple longitudinal plates 41. The longitudinal plates 41 are arranged at intervals along the circumference of the tank body. The longitudinal plate is a plate that extends longitudinally. A baffle 5 is installed on the longitudinal plate 41. The connecting plate and the longitudinal plate are in contact with the cavity wall of the tank body.

[0024] The baffle 5 is flat, and the angle between the baffle 5 and the cavity wall of the tank 1 is 25-35°, specifically 30°. In this example, the stirring shaft 32 in the stirring mechanism extends into the cavity enclosed by the fixed frame 4.

[0025] For the installation of the baffle, if a groove is formed on the longitudinal plate 41, the side of the baffle 5 can be embedded in the groove and further welded for fixation.

[0026] Regarding the connection between the fixing frame and the cover plate, the fixing frame 4 also includes a horizontally extending fixing plate 43, which is connected to the connecting plate 42 at the top. The fixing plate 43 and the cover plate 2 are fixed together by bolts or welding.

[0027] To improve the stability of the fixing frame, a protrusion 10 can be formed on the wall of the tank body 1, a positioning groove can be formed on the side of the protrusion 10 facing the fixing frame, and a protrusion 44 can be formed on the bottom surface of the connecting plate 42 at the bottom, so that the protrusion 44 is embedded in the positioning groove to improve the stability of the fixing frame.

[0028] During assembly, if a pre-formed frame is used, baffles are then installed on the frame. The frame is then fixed to the cover plate, and assembly is completed directly when the cover plate is connected to the tank body, thus speeding up the assembly process.

[0029] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
