Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary material addition equipment, and in particular to an auxiliary material addition equipment for concrete production. Background Technology

[0002] Concrete is a building material made by mixing various materials in a certain proportion, mainly including cement, water, coarse aggregate (mainly gravel), and fine aggregate (mainly sand). Concrete admixtures (concrete additives and mineral admixtures) are the core of modern concrete technology, and they can significantly improve the performance of concrete. However, when concrete admixtures are put into processing equipment nowadays, it is easy for them to accumulate in one place in the processing equipment. When multiple admixtures are added, they cannot be evenly distributed in the processing equipment, which reduces the mixing efficiency and effect of concrete raw materials and admixtures. Utility Model Content

[0003] This utility model discloses an auxiliary material addition device for concrete production, which solves the problem that various auxiliary materials cannot be evenly distributed in the processing equipment when they are added.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A concrete production auxiliary material addition device includes a mixing tank, a support frame fixed on the mixing tank, a connecting cylinder fixed inside the support frame, a fixed plate fixed inside the connecting cylinder, an opening on the fixed plate, a mixing blade on the fixed plate, a motor for driving the mixing blade to rotate inside the support frame, a movable plate with an arc-shaped top below the fixed plate, a sealing block located inside the opening on the top of the movable plate, and an electric telescopic rod for driving the movable plate to rise and fall inside the support frame.

[0005] Compared with the prior art, the present invention has the following beneficial effects: Multiple auxiliary materials are separately added into the connecting cylinder, where they are supported by a fixed plate. The motor drives the mixing blades to rotate, pre-mixing the various auxiliary materials. Then, an electric telescopic rod drives a moving plate downwards, causing a sealing block to move out of the opening. The pre-mixed auxiliary materials then fall through the opening to the top of the moving plate, and from there slide down into the mixing tank to mix with the concrete raw materials. This invention allows for the pre-mixing of multiple auxiliary materials, ensuring that they are evenly distributed within the concrete raw materials in the mixing tank after pre-mixing. This avoids the accumulation of multiple auxiliary materials in one place, improving the mixing efficiency and effect of the concrete raw materials and auxiliary materials.

[0008] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0009] like Figure 1 , Figure 2 and Figure 3As shown, this utility model provides an auxiliary material addition device for concrete production, including a mixing tank 1, a support frame 2 fixed on the mixing tank 1, a connecting cylinder 21 fixed inside the support frame 2, a fixing plate 22 fixed inside the connecting cylinder 21, an opening 23 on the fixing plate 22, a mixing blade 24 on the fixing plate 22, and a motor 25 for driving the mixing blade 24 to rotate inside the support frame 2; a movable plate 3 with an arc-shaped top is provided below the fixing plate 22, a sealing block 31 located inside the opening 23 is fixed at the top of the movable plate 3, and an electric telescopic rod 32 for driving the movable plate 3 to rise and fall is fixed inside the support frame 2. The bottom of the connecting cylinder 21 is connected to a fixing pipe 4, the diameters at both ends of the fixing pipe 4 are smaller than the diameter at the middle, and a perforated plate 41 is fixed at the lower part inside the fixing pipe 4; a rod 34 that can be inserted into the perforation on the perforated plate 41 is fixed at the bottom of the movable plate 3. Multiple auxiliary materials are fed into the connecting cylinder 21, where they are supported by the fixed plate 22. The motor 25 drives the stirring blade 24 to rotate, premixing the auxiliary materials. Then, the electric telescopic rod 32 drives the moving plate 3 downward, allowing it to enter the middle of the fixed tube 4. This causes the sealing block 31 to move out of the opening 23, and the premixed auxiliary materials fall through the opening 23 to the top of the moving plate 3. The top surface of the sealing block 31 is slightly tilted (not shown in the figure) to prevent auxiliary materials from accumulating on top of the sealing block 31. After the premixed auxiliary materials slide from the top of the moving plate 3 onto the perforated plate 41, auxiliary materials of the appropriate volume can pass through the perforated plate 41. The material is evenly dropped into the feed inlet at the top of the mixing tank 1 through the perforated plate 41 and then mixed with the concrete raw materials. Larger or lumpy auxiliary materials are blocked by the perforated plate 41. Then, the electric telescopic rod 32 continues to drive the moving plate 3 to move downward, so that the insert rod 34 passes through the perforation (a set of insert rods 34 is provided). The auxiliary materials blocked in the perforation can be pushed out. At the same time, the moving plate 3 can crush the larger or lumpy auxiliary materials (after the moving plate 3 crushes the auxiliary materials, a small amount of auxiliary materials will adhere to the bottom of the moving plate 3, but most of the auxiliary materials will fall downward and will not affect the mixing of auxiliary materials and concrete raw materials), so that the auxiliary materials continue to fall downward through the perforation.

[0010] like Figure 1 and Figure 2As shown, a hopper 5 extends through the top of the support frame 2. A vertical pipe 51 is rotatably connected to the discharge end of the hopper 5. The stirring blade 24 is connected to the vertical pipe 51, and a discharge pipe 52 located inside the connecting cylinder 21 is connected to the vertical pipe 51. The main body of the motor 25 is connected to the hopper 5 via a connecting plate. A drive gear is fixed on the shaft of the motor 25, and a driven gear meshing with the drive gear is fixed on the vertical pipe 51. A set of weighing plates 9 is embedded in the top of the support frame 2, and a storage frame 6 is placed on the weighing plates 9. The discharge end of the storage frame 6 corresponds to the top of the hopper 5. A control panel 8 is fixed on the support frame 2. Starting the motor 25 causes the drive gear to rotate the vertical tube 51 via the driven gear, causing the stirring blades 24 to stir and premix the auxiliary materials in the connecting cylinder 21. Multiple auxiliary materials can be stored separately in a set of storage boxes 6. When additional materials are needed, the solenoid valve on the discharge end of the storage box 6 can be opened to discharge the various auxiliary materials into the discharge hopper 5. The weighing plate 9 displays the weight of the auxiliary materials in the storage box 6 on the display screen of the control panel 8, allowing staff to know the weight of the auxiliary materials in the storage box 6 for easier operation. For precise addition, the control panel 8 is electrically connected to the electric telescopic rod 32 and the motor 25 respectively. When various auxiliary materials enter the vertical pipe 51 through the discharge end at the bottom of the hopper 5, the auxiliary materials in the vertical pipe 51 can be discharged through the discharge pipe 52. As the vertical pipe 51 drives the discharge pipe 52 to rotate, the auxiliary materials can be evenly distributed on the fixed plate 22, so as to improve the premixing efficiency of various auxiliary materials. The part of the vertical pipe 51 below the discharge pipe 52 is solid, which avoids the accumulation of auxiliary materials at the bottom of the discharge pipe 52.

[0011] like Figure 1 and Figure 2 As shown, the telescopic end of the electric telescopic rod 32 is fixed with a connecting rod 33 that passes through the fixed plate 22, and the bottom end of the connecting rod 33 is connected to the moving plate 3; a limiting ring 7 that covers the stirring blade 24 is fixed on the fixed plate 22, and the connecting rod 33 is located outside the limiting ring 7. A baffle 53 that blocks the top of the connecting cylinder 21 is fixed on the vertical pipe 51. There are two electric telescopic rods 32, and the telescopic ends of the electric telescopic rods 32 are fixed to the connecting rods 33 through floating joints. The connecting rods 33 are slidably connected to the fixed plate 22, which avoids the telescopic ends of the electric telescopic rods 32 being affected by lateral forces. The two electric telescopic rods 32 operate in a master-slave follow mode, which is a very mature existing technology and will not be described in detail here. The limiting ring 7 can limit the auxiliary materials falling on the fixed plate 22, and the baffle 53 can block the top of the connecting cylinder 21 to prevent the auxiliary materials from splashing outside the connecting cylinder 21 during the mixing process. The mixing box 1 can be a commercially available equipment for mixing concrete, which will not be described in detail here.

[0012] All electrical components in this application are electrically connected to the controller and power supply. The control method of this utility model is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0013] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
