Description

Technical Field

[0001] This utility model belongs to the field of pipeline technology, specifically relating to an additive pipeline. Background Technology

[0002] Accelerators: Admixtures added to concrete to enable it to set and harden rapidly; the main types are inorganic salts and organic compounds. Powdered solids, their dosage is only 2% to 3% of the cement content in concrete, yet they can cause concrete to initially set within 5 minutes, while accelerators set within 12 minutes; thus achieving the purpose of rapid setting of concrete in emergency repairs or tunnels. They are indispensable additives in shotcrete construction. Their function is to accelerate the hydration and hardening of cement, forming sufficient strength in a very short time to meet the requirements of special construction.

[0003] In the manufacturing process of quick-setting agents, various additives need to be added for stirring and neutralization. Generally, the additives are introduced into the mixing tank through pipes. However, when some powdered reagents are transported in the pipes, the powdered reagents are also prone to clumping, which will greatly reduce the mixing efficiency of the mixing tank. Utility Model Content

[0004] In order to solve the above-mentioned problems in the existing technology, the purpose of this utility model is to provide an admixture delivery pipeline.

[0005] The technical solution adopted in this utility model is as follows:

[0006] An admixture delivery pipeline includes a pipe body and a discharge head, the discharge head being connected to the front end of the pipe body, and the pipe body and the discharge head being provided with a powder multi-dispersing component.

[0007] The powder multi-dispersing component includes: a first drive frame, a first drive motor, a rotating shaft, a mesh frame, a second drive frame, a second drive motor, a transmission groove, a stirring shaft, a transmission gear, and a stirring rack.

[0008] The first drive frame is installed on the pipe body, the first drive motor is installed inside the first drive frame, the rotating shaft is installed inside the pipe body and connected to the output end of the first drive motor, the mesh frame is installed on the rotating shaft, the second drive frame is installed on the discharge pipe head, the second drive motor is installed inside the second drive frame, the transmission groove is opened above the discharge pipe head, the stirring shaft passes through the transmission groove and is installed inside the discharge pipe head, the stirring frame is installed on the stirring shaft, and the transmission gear is fitted on the stirring shaft in the transmission groove and meshes with each other.

[0009] Preferably, the grid frame is designed as a disc with the same diameter as the tube body.

[0010] Preferably, the positions of the stirring racks are staggered vertically.

[0011] Preferably, the grid frames are arranged at equal intervals inside the tube.

[0012] This additive delivery pipeline has the following beneficial effects:

[0013] This invention utilizes a multi-stage powder dispersing component. When the powder is conveyed in the pipeline, multiple sets of rotating mesh frames and a stirring frame at the pipeline outlet can repeatedly disperse clumps of powder before it enters the mixing tank for mixing. This ensures the looseness of the powder and prevents clumped powder from entering the mixing tank and reducing mixing efficiency. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model; that is, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The components of the embodiments of the present utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] The following is combined Figure 1-4 The present invention describes a specific embodiment of an additive delivery pipeline, comprising a pipe body 1 and a discharge pipe head 2, wherein the discharge pipe head 2 is connected to the front end of the pipe body 1, and the pipe body 1 and the discharge pipe head 2 are provided with a powder multi-dispersing component.

[0022] The powder multi-dispersing assembly includes: a first drive frame 3, a first drive motor 4, a rotating shaft 5, a mesh frame 6, a second drive frame 7, a second drive motor 8, a transmission groove 9, a stirring shaft 10, a transmission gear 11, and a stirring rack 12.

[0023] The first drive frame 3 is installed on the tube body 1, the first drive motor 4 is installed inside the first drive frame 3, the rotating shaft 5 is installed inside the tube body 1 and connected to the output end of the first drive motor 4, the mesh frame 6 is installed on the rotating shaft 5, the second drive frame 7 is installed on the discharge pipe head 2, the second drive motor 8 is installed inside the second drive frame 7, the transmission groove 9 is opened above the discharge pipe head 2, the stirring shaft 10 passes through the transmission groove 9 and is installed inside the discharge pipe head 2, the stirring frame 12 is installed on the stirring shaft 10, and the transmission gear 11 is fitted on the stirring shaft 10 in the transmission groove 9 and meshes with each other.

[0024] It should be noted that after the powdered reagent is drawn into the tube body 1, the first drive motor 4 drives the rotating shaft 5 and the grid frame 6 to rotate, and the second drive motor 8 drives the transmission gear 11 to rotate, so that multiple sets of stirring racks 12 can start to rotate. When the powder passes through multiple sets of rotating grid frames 6, the powder can be dispersed multiple times. Then, when the powder is discharged from the pipe, it prevents the powder from clumping together during the transmission process in the pipe.

[0025] Preferably, the grid frame 6 is designed as a disc with the same diameter as the tube body 1.

[0026] It should be noted that the disc-shaped grid frame 6, which fits the inner diameter of the tube body 1, allows for more comprehensive mixing of the powder.

[0027] Preferably, the positions of the stirring rack 12 are staggered vertically.

[0028] It should be noted that the staggered shape of the stirring rack 12 can prevent large powder particles from leaking out from the gaps between the stirring racks 12.

[0029] Preferably, the grid frames 6 are arranged at equal intervals inside the tube body 1.

[0030] It should be noted that the equally spaced grid frame 6 can disperse the powder again after conveying it a certain distance, preventing the powder from clumping together again after the first dispersion process.
