[0002] A concrete mixing plant is a mechanical device specifically designed to mix raw materials such as cement, water, sand, and gravel into uniform concrete. It is widely used in construction sites, ready-mixed concrete plants, and various infrastructure construction projects. Existing vertical concrete mixing plants typically use a main shaft to drive multiple mixing blades to rotate for a period of time in order to achieve thorough mixing of raw materials such as cement, water, sand, and gravel.

[0003] However, during the operation of existing concrete mixing equipment, concrete residue and adhesion easily occur on the inner wall of the concrete mixing drum, which significantly increases the weight of the mixing drum, leading to increased energy consumption and reduced mixing efficiency.

[0004] Applying a coating directly to the inner wall of a concrete mixing drum using traditional methods results in wear or peeling, requiring overall repair or recoating, which is time-consuming and costly. Utility Model Content

[0005] The technical problem this invention aims to solve is that the inner wall space of the concrete mixing drum is narrow, making it difficult to guarantee the uniformity of spraying after the coating peels off. This requires the use of special equipment or segmented construction, which is inconvenient.

[0006] The technical solution adopted by this utility model is as follows:

[0007] The energy-saving concrete mixing device proposed in this utility model includes a mixing drum body, a discharge valve at the lower part of the mixing drum body, a mixing equipment frame at the upper part of the mixing drum body, a motor passing through the upper part of the mixing equipment frame, a rotating shaft fixedly connected to the output shaft of the motor, and mixing blades fixedly connected to the rotating shaft. It also includes two sets of detachable arc-shaped components that are movably inserted into the inner wall of the mixing drum body. The two sets of detachable arc-shaped components can be joined together circumferentially along the inner wall of the mixing drum body to form a complete annular structure coaxial with the mixing drum body. The inner surface of the detachable arc-shaped components is coated with epoxy resin and has uniformly distributed serrated protrusions.

[0008] Furthermore, connecting blocks are fixed to both sides of the outer surface of the detachable arc-shaped component, and two adjacent sets of connecting blocks are penetrated by a double-ended stud, with nuts screwed to both ends of the double-ended stud.

[0009] Furthermore, a limiting groove is provided on the upper part of the outer wall of the stirring cylinder body to be movably engaged with the connecting block.

[0010] Furthermore, a fixed base located below the limiting slot is fixedly connected to the outer wall on both sides of the mixing drum body, and a cylinder is fixedly connected to the upper part of the fixed base. A push plate located below the connecting block is fixedly connected to the output end of the cylinder.

[0011] Furthermore, a U-shaped card holder is fixedly connected to the lower part of the connecting block, and two sets of limiting blocks that are inserted and cooperate with the U-shaped card holder are fixedly connected to the pushing plate.

[0012] Furthermore, a connecting seat is fixedly connected to the outer wall of the mixing drum body, a guide rod that is slidably connected to the upper part of the connecting seat is fixedly connected to the upper part of the mixing equipment frame, a top seat is fixedly connected to the top of the guide rod, a second cylinder passes through the top seat, and a U-shaped frame integrally formed with the mixing equipment frame is fixedly connected to the output end of the second cylinder.

[0013] The beneficial effects of this utility model by adopting the above structure are as follows:

[0014] 1. By setting a detachable and replaceable inner layer structure with a coating, the problem of troublesome spraying after the coating of the traditional mixing drum is solved. By reducing concrete residue and adhesion, energy saving can be indirectly achieved, while improving transportation efficiency.

[0015] 2. Modular installation of the connection structure improves the stability of the inner structure during use and facilitates disassembly and assembly. Attached Figure Description

[0022] Example 1:

[0023] like Figure 1 , Figure 2 , Figure 4 As shown, the energy-saving concrete mixing device proposed in this utility model includes a mixing drum body 1, a discharge valve 11 at the lower part of the mixing drum body 1, a mixing equipment frame 2 at the upper part of the mixing drum body 1, a motor 21 passing through the upper part of the mixing equipment frame 2, a rotating shaft 22 fixedly connected to the output shaft of the motor 21, and mixing blades 23 fixedly connected to the rotating shaft 22. It also includes two sets of detachable arc-shaped components 3 movably inserted into the inner wall of the mixing drum body 1, and the two sets of detachable arc-shaped components 3 can be joined together circumferentially along the inner wall of the mixing drum body 1 to form a coaxial structure with the mixing drum body 1. The complete annular structure has an epoxy resin coating on the inner surface of the detachable arc-shaped component 3. The hydrophobicity and smooth surface of the epoxy resin coating can reduce concrete adhesion and reduce residue inside the cylinder. With reduced residue, the amount of water used for rinsing the cylinder, the energy consumption of the high-pressure water pump, and the time cost can all be reduced. The inner surface of the detachable arc-shaped component 3 has uniformly distributed serrated protrusions, which can disrupt the laminar flow of concrete, increase turbulence, improve mixing uniformity, and the edges of the protrusions cut concrete clumps, which can reduce adhesion and optimize the fluidity and mixing efficiency of concrete, thereby reducing residue and adhesion and reducing energy consumption.

[0024] like Figure 3 , 4 As shown in Figure 5, connecting blocks 31 are fixed to both sides of the outer surface of the detachable arc-shaped component 3. Two adjacent sets of connecting blocks 31 are penetrated by a double-headed stud 32, and nuts are screwed to both ends of the double-headed stud 32. After the two sets of connecting blocks 31 are combined, they are locked and fixed by installing the double-headed stud 32. A limiting groove 4 is provided on the upper part of the outer wall of the stirring drum body 1 to be movably engaged with the connecting block 31. After the limiting groove 4 is engaged with the connecting block 31, displacement of the detachable arc-shaped component 3 is prevented during the stirring process.

[0025] Example 2:

[0026] like Figure 1 , 5 As shown, a fixed base 5 located below the limiting slot 4 is fixedly connected to the outer wall of both sides of the mixing drum body 1. A cylinder 51 is fixedly connected to the upper part of the fixed base 5. A push plate 52 located below the connecting block 31 is fixedly connected to the output end of the cylinder 51. A U-shaped bracket 6 is fixedly connected to the lower part of the connecting block 31. Two sets of limiting blocks 61 that are inserted and cooperate with the U-shaped bracket 6 are fixedly connected to the push plate 52.

[0027] During the extension process of the output end of cylinder 51, the limiting block 61 is locked in the entrance-shaped bracket 6 to achieve the limiting, and the stability is enhanced during the upward movement of the connecting block 31 and the detachable arc-shaped component 3 by the push plate 52.

[0028] like Figure 1 , 2 As shown, a connecting seat 7 is fixedly connected to the outer wall of the mixing drum body 1. A guide rod 71, which is slidably connected to the mixing equipment frame 2, is fixedly connected to the upper part of the connecting seat 7. A top seat 72 is fixedly connected to the top of the guide rod 71. A cylinder 73 passes through the top seat 72. A U-shaped frame 74, which is integrally formed with the mixing equipment frame 2, is fixedly connected to the output end of the cylinder 73. In actual use, the output end of the cylinder 73 extends and retracts, pulling the U-shaped frame 74 to drive the mixing equipment frame 2 to be raised and lowered on the guide rod 71. After the mixing blade 23 is moved up, it is convenient to disassemble and assemble the detachable arc-shaped component 3.

[0029] The above is the entire usage process of the energy-saving concrete mixing plant.

[0030] The present invention and its embodiments have been described above.
