Description
Technical Field
[0001] This utility model relates to the field of asphalt mixture production technology, and in particular to a multifunctional direct-fall double-layer superimposed mixing equipment. Background Technology
[0002] Asphalt mixture is a composite material, mainly composed of asphalt, coarse aggregate, fine aggregate, and mineral powder, and some also contain polymers and wood cellulose; different structures are formed by mixing these materials of different qualities and quantities, and they have different mechanical properties.
[0003] The existing asphalt mixture production process requires the use of mixing equipment. However, due to the wide variety of raw materials used in asphalt mixtures, adding multiple mixtures to a single mixing tank at a time not only increases the difficulty of mixing but also increases the burden on the mixing equipment, reducing its service life. Utility Model Content
[0004] The main purpose of this invention is to provide a multifunctional direct-fall double-layer superimposed mixing device.
[0005] The objective of this utility model can be achieved by adopting the following technical solution:
[0006] A multifunctional direct-fall double-layer superimposed mixing equipment includes a tower body, a first mixing cylinder installed on one side of the upper part of the tower body, a second mixing cylinder arranged on one side below the first mixing cylinder, and a mixing mechanism installed on both the first and second mixing cylinders. A discharge pipe is installed at one bottom end of both the first and second mixing cylinders, and a discharge mechanism is installed inside the discharge pipe. An asphalt feeding pipe is installed on one side of both the first and second mixing cylinders.
[0007] Preferably, the first stirring tank and the second stirring tank have an inclined structure, and the first stirring tank and the second stirring tank are distributed in parallel in the vertical direction.
[0008] Preferably, the stirring mechanism includes a drive motor, a transmission box, a support shaft, and a stirring frame.
[0009] Preferably, the output end of the drive motor is fixedly connected to the drive mechanism inside the transmission box, and the drive mechanism inside the transmission box is fixedly connected to the support shaft.
[0010] Preferably, the stirring frame is fixed to the outside of the support shaft, and the other end of the support shaft is connected to the bearings of the first stirring cylinder and the second stirring cylinder, respectively.
[0011] Preferably, the discharge mechanism includes a connecting shaft and a baffle, and the baffle is fixed to the outside of the connecting shaft, and a rotating motor is installed on the outside of the connecting shaft.
[0012] Preferably, a water supply pipe is installed on the second mixing cylinder on one side of the asphalt feeding pipe.
[0013] Preferably, the discharge pipe located at the bottom of the first mixing cylinder is located on the side above the second mixing cylinder.
[0014] The beneficial effects of this technology are:
[0015] By setting up a first mixing tank, a second mixing tank, a mixing mechanism, a discharge pipe, and a discharge mechanism, some raw materials can be added to the first mixing tank and mixed by the mixing mechanism. After mixing, the discharge mechanism is opened to allow the mixture to fall into the second mixing tank through the discharge pipe. Then, the remaining raw materials are added to the second mixing tank and mixed by the mixing mechanism. This improves the uniformity of mixing, reduces the difficulty of mixing, reduces the burden on the mixing equipment, and extends its service life.
[0016] In the process of mixing asphalt mixtures, the first mixing cylinder and the second mixing cylinder are distributed in parallel in the vertical direction and are both inclined. This can improve the discharge of the mixture by its own gravity. No other conveying equipment is needed during the discharge process, which not only reduces production costs but also occupies a small area. Attached Figure Description

[0022] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.
[0023] like Figures 1-3 As shown in the figure, this embodiment provides a multi-functional direct-fall double-layer superimposed mixing device, including a tower body 1. A first mixing cylinder 2 is installed on one side of the upper part of the tower body 1. The first mixing cylinder 2 is used to mix part of the raw materials. A second mixing cylinder 3 is arranged on one side below the first mixing cylinder 2. The second mixing cylinder 3 is used to mix the remaining raw materials. Both the first mixing cylinder 2 and the second mixing cylinder 3 are equipped with a mixing mechanism 4. A discharge pipe 6 is installed at one end of the bottom of both the first mixing cylinder 2 and the second mixing cylinder 3 to facilitate the discharge of materials in the first mixing cylinder 2 and the second mixing cylinder 3 through the discharge pipe 6. A discharge mechanism 7 is installed in the discharge pipe 6. An asphalt feeding pipe 5 is installed on one side of both the first mixing cylinder 2 and the second mixing cylinder 3 to facilitate the delivery of emulsified asphalt to the first mixing cylinder 2 and the second mixing cylinder 3 respectively through the asphalt feeding pipe 5.
[0024] like Figures 1-3 As shown, the first mixing tank 2 and the second mixing tank 3 are inclined and parallel to each other in the vertical direction, so that the material in the first mixing tank 2 can fall into the second mixing tank 3 by its own gravity.
[0025] like Figures 1-3 As shown, the mixing mechanism 4 includes a drive motor 401, a transmission box 402, a support shaft 403, and a mixing frame 404, which facilitates the mixing of asphalt mixture through the mixing mechanism 4.
[0026] like Figures 1-3 As shown, the output end of the drive motor 401 is fixedly connected to the drive mechanism inside the transmission box 402. The drive mechanism inside the transmission box 402 is fixedly connected to the support shaft 403, which enables the drive motor 401 to drive the support shaft 403 to rotate through the transmission box 402, and the transmission box 402 can increase the rotation torque.
[0027] like Figures 1-3 As shown, the mixing frame 404 is fixed on the outside of the support shaft 403, and the other end of the support shaft 403 is connected to the bearings of the first mixing cylinder 2 and the second mixing cylinder 3 respectively, so that the support shaft 403 can drive the mixing frame 404 to rotate and mix the mixture.
[0028] like Figures 1-3 As shown, the discharge mechanism 7 includes a connecting shaft 701 and a baffle 702, with the baffle 702 fixed on the outside of the connecting shaft 701. A rotating motor 8 is installed on the outside of the connecting shaft 701, so that the rotating motor 8 can drive the baffle 702 to rotate through the support shaft 403, thereby controlling the opening and closing of the discharge pipe 6.
[0029] like Figures 1-3 As shown, a water supply pipe 9 is installed on one side of the asphalt feeding pipe 5 on the second mixing cylinder 3, which facilitates the injection of clean water into the second mixing cylinder 3 through the water supply pipe 9.
[0030] like Figures 1-3 As shown, the discharge pipe 6 located at the bottom of the first mixing tank 2 is located on the side above the second mixing tank 3, which facilitates the mixing material in the first mixing tank 2 to enter the second mixing tank 3.
[0031] The working principle of this device is as follows: In actual use, coarse aggregate is conveyed to the first mixing cylinder 2 on the tower body 1 via an external belt conveyor. At this time, water is injected into the first mixing cylinder 2 through the water supply pipe 9. The drive motor 401 in the mixing mechanism 4 drives the support shaft 403 to rotate through the transmission box 402. The support shaft 403 then drives the mixing frame 404 to rotate, and the mixing frame 404 mixes the material. While the coarse aggregate is falling and being mixed, mineral powder and cement are continuously added to the first mixing cylinder 2. Emulsified asphalt is also sprayed into the first mixing cylinder 2 through the asphalt feeding pipe 5. The mixture is stirred until it becomes a smooth, white mixture. After stirring, manufactured sand is fed into the first mixing tank 2, and clean water is injected into the first mixing tank 2 to wet it again. At the same time, the remaining mineral powder and cement are added. Then, the motor 8 is rotated to drive the baffle 702 to rotate through the support shaft 403. The premixed mixture in the first mixing tank 2 falls into the second mixing tank 3 through the discharge pipe 6. During the falling process, emulsified asphalt is sprayed into the second mixing tank 3 through the asphalt feeding pipe 5. The mixture is then finally mixed by the mixing device on the second mixing tank 3. After mixing, the mixture is directly conveyed to the silo through the discharge pipe 6 on the second mixing tank 3.
[0032] The above are merely further embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.
