Description

Technical Field

[0001] This utility model relates to the field of concrete admixture production technology, and in particular to concrete admixture mixing device. Background Technology

[0002] Concrete admixtures are key materials added during the concrete mixing process to improve its performance. During their preparation, the components must be thoroughly stirred to ensure uniform reaction in order to achieve optimal results in practical applications.

[0003] Currently, the widely used tipping bucket mixer is used to mix concrete admixtures, achieving thorough mixing of the admixtures through rotating the mixing tank.

[0004] However, due to the high viscosity of concrete admixtures, a large amount of material will adhere to the tank wall during mixing. This adhesion phenomenon leads to insufficient mixing of materials and incomplete internal reaction, which seriously affects product quality. At the same time, during the discharge stage, the adhered material is difficult to completely discharge, resulting in waste and increasing the difficulty of cleaning. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0006] Therefore, one objective of this utility model is to provide a concrete admixture mixing device that, through a transmission component and a connecting mechanism, transmits the power driving the mixing tank to the internal mixing component. This not only effectively scrapes off the adhering material from the tank wall and eliminates residue, but also, through multi-directional composite mixing, enables the material to withstand stronger shearing and convection, ultimately significantly improving the mixing uniformity and reaction sufficiency of the concrete admixture.

[0007] To achieve the above objectives, the first aspect of this utility model provides a concrete admixture mixing device, comprising: a supporting base plate, two supporting frames, a mixing tank, a drive assembly, a mixing assembly, and a transmission assembly. The two supporting frames are respectively fixedly installed on the top of the supporting base plate. The mixing tank is disposed between the two supporting frames, and a connecting mechanism is provided between the mixing tank and the two supporting frames to connect them. The drive assembly is disposed between the supporting base plate and the connecting mechanism, and is connected to the connecting mechanism. The mixing assembly includes a first mixing mechanism and a second mixing mechanism, wherein the first mixing mechanism is disposed at one end inside the mixing tank, and the second mixing mechanism is disposed at the other end inside the mixing tank. The transmission assembly is disposed on the outside of the mixing tank, and is connected to the first mixing mechanism, the second mixing mechanism, and the connecting mechanism.

[0008] In addition, the concrete admixture mixing device proposed above according to this utility model may also have the following additional technical features: Specifically, the connecting mechanism includes a fixed shaft, a rotating shaft, and a dust cover. The fixed shaft is fixedly connected to one side of the mixing tank and is rotatably connected to the corresponding support frame. The rotating shaft is rotatably connected to the other side of the mixing tank and is fixedly connected to the corresponding support frame. The dust cover is fixedly installed on the side of the mixing tank near the rotating shaft and is rotatably connected to the rotating shaft. One end of the mixing tank is connected to an inlet / outlet pipe.

[0009] Specifically, the first stirring mechanism includes a first sealing plate and a stirring frame, wherein the first sealing plate is rotatably connected to one end of the inner side of the stirring tank, the stirring frame is rotatably connected to the inside of the stirring tank, and the stirring frame is fixedly connected to the first sealing plate, and a plurality of stirring rods are provided on the inner side of the stirring frame.

[0010] Specifically, the second stirring mechanism includes a second sealing plate and a stirring shaft. The second sealing plate is rotatably connected to the other end of the inner side of the stirring tank, the stirring shaft is rotatably connected to the inner side of the stirring frame, and the stirring shaft is fixedly connected to the second sealing plate. Multiple stirring rods are provided on the outer side of the stirring shaft.

[0011] Specifically, the transmission assembly includes a first transmission shaft, a first bevel gear, a second transmission shaft, a second bevel gear, and a third bevel gear. The first transmission shaft is rotatably connected to the inside of the dust cover. A first sprocket mechanism is provided between one end of the first transmission shaft and the first sealing plate, connecting them. The first bevel gear is fixedly connected to the other end of the first transmission shaft. The second transmission shaft is rotatably connected to the inside of the dust cover. A second sprocket mechanism is provided between one end of the second transmission shaft and the second sealing plate, connecting them. The second bevel gear is fixedly connected to the other end of the second transmission shaft. The third bevel gear is fixedly connected to the outside of the rotating shaft and meshes with both the first bevel gear and the second bevel gear.

[0012] Compared with the prior art, this utility model has the following beneficial effects: by using a single drive system to simultaneously achieve the tilting of the mixing tank and the counter-rotation of the internal dual stirring mechanisms, the integration of the equipment is improved. This design helps to scrape off the adhering substances on the tank wall and reduce material residue. At the same time, by enhancing the shearing and convection between materials, the mixing uniformity can be effectively improved. The tilting design of the tank also facilitates the discharge and cleaning of materials, and to a certain extent solves the problems of insufficient mixing and excessive residue in traditional stirring devices.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0020] The concrete admixture mixing device of this utility model is described below with reference to the accompanying drawings.

[0021] like Figures 1-4 As shown in the figure, a concrete admixture mixing device according to an embodiment of the present invention includes: a supporting base plate 1, two supporting frames 2, a mixing tank 3, a driving assembly 5, a mixing assembly 6, and a transmission assembly 7.

[0022] Two support frames 2 are fixedly installed on the top of the support base plate 1, and the mixing tank 3 is set between the two support frames 2. A connecting mechanism 4 is provided between the mixing tank 3 and the two support frames 2, and the connecting mechanism 4 is connected to the support frame 2 and the mixing tank 3 respectively.

[0025] It should be noted that the drive assembly 5 includes a motor and two first sprockets.

[0028] Specifically, when producing concrete admixtures, relevant technicians need to use this device to mix the admixtures.

[0029] First, the technicians start the motor, which drives the fixed shaft 41 and the mixing tank 3 to rotate through the first sprocket and chain. After the inlet and outlet pipes on the mixing tank 3 rotate to the top of the device, the motor is locked, thereby locking the position of the mixing tank 3. The technicians first open the valve on the inlet and outlet pipes, add the concrete admixture to be mixed into the inside of the mixing tank 3, and then close the valve to complete the loading of raw materials.

[0030] Next, the technicians turned on the motor again and adjusted its speed so that the mixing tank 3 could rotate at a suitable speed according to the mixing requirements. The rotating shaft 42 in the connecting mechanism 4 could transmit the driving force of the drive component 5 to the mixing component 6 through the transmission component 7, so that the first mixing mechanism 61 and the second mixing mechanism 62 in the mixing component 6 would rotate in opposite directions. While cleaning the inner wall of the mixing tank 3, the concrete admixture was further mixed to complete the full mixing of the concrete admixture.

[0031] Finally, the technicians adjusted the rotation of the mixing tank 3 by using a motor, causing the inlet and outlet pipes to move to the bottom of the device, and opened the valves on the inlet and outlet pipes to smoothly discharge the mixed concrete admixture.

[0032] In one embodiment of this utility model, such as Figure 3 and Figure 4 As shown, the first stirring mechanism 61 includes a first sealing plate 611 and a stirring frame 612.

[0035] The second stirring mechanism 62 includes a second sealing plate 621 and a stirring shaft 622.

[0036] The second sealing plate 621 is rotatably connected to the other end of the inner side of the mixing tank 3, the stirring shaft 622 is rotatably connected to the inner side of the stirring frame 612, and the stirring shaft 622 is fixedly connected to the second sealing plate 621.

[0037] It should be noted that a rotating sealing ring is provided between the second sealing plate 621 and the mixing tank 3, so that the second sealing plate 621 can maintain a seal with the mixing tank 3 at all times when it rotates.

[0038] It should be noted that the mixing rods on the mixing frame 612 and the mixing shaft 622 are arranged in a cross manner, which can shear and mix the concrete admixture when the mixing frame 612 and the mixing shaft 622 rotate.

[0039] In one embodiment of this utility model, such as Figure 3 and Figure 4 As shown, the transmission assembly 7 includes a first transmission shaft 71, a first bevel gear 72, a second transmission shaft 73, a second bevel gear 74, and a third bevel gear 75.

[0040] The first drive shaft 71 is rotatably connected to the inside of the dust cover 43. A first sprocket mechanism is provided between one end of the first drive shaft 71 and the first sealing plate 611, and the first sprocket mechanism is connected to the first drive shaft 71 and the first sealing plate 611 respectively.

[0041] It should be noted that the first sprocket mechanism includes two second sprockets. The two second sprockets are respectively fixedly installed at one end of the first drive shaft 71 near the first sealing plate 611 and on one side of the first sealing plate 611, and chains are sleeved on the outer sides of the two second sprockets.

[0042] The first bevel gear 72 is fixedly connected to the other end of the first drive shaft 71.

[0043] The second drive shaft 73 is rotatably connected to the inside of the dust cover 43. A second sprocket mechanism is provided between one end of the second drive shaft 73 and the second sealing plate 621, and the second sprocket mechanism is connected to the second drive shaft 73 and the second sealing plate 621 respectively.

[0044] It should be noted that the second sprocket mechanism includes two third sprockets.

The second drive shaft 73 drives the second sealing plate 621 and the mixing shaft 622 to rotate via the third sprocket. The mixing shaft 622 and the mixing frame 612 rotate in opposite directions. The mixing frame 612 cleans the inner wall of the mixing tank 3. The mixing rods on the mixing frame 612 and the mixing shaft 622 shear and mix the concrete admixture.

[0048] In summary, the concrete admixture mixing device of this utility model realizes the rotation of the mixing tank 3 and the internal dual-shaft counter-directional mixing function through a set of drive systems. During operation, the motor drives the mixing tank 3 to revolve through the sprocket mechanism, and at the same time, the power is transmitted to the first mixing mechanism 61 and the second mixing mechanism 62 inside through the bevel gear set in the transmission component 7, so that the two achieve counter-rotation, forming strong shear force and convection effect, which significantly improves the mixing uniformity. In addition, the mixing rack 612 can effectively scrape off the adhering material on the tank wall and reduce material residue.
