Description

Technical Field

[0001] This utility model relates to the field of concrete mixing technology, and in particular to a raw material processing and mixing structure for reinforced concrete drainage pipes. Background Technology

[0002] Reinforced concrete drainage pipes are widely used in urban construction, municipal road construction, and farmland water conservancy projects both domestically and internationally for gravity flow pipelines such as rainwater, sewage, water diversion, and farmland irrigation and drainage, due to their unique advantages such as high external pressure resistance, good durability, long service life, low production cost, convenient manufacturing, and low price. Their manufacturing process involves the mixing of various raw materials, including concrete, steel bars, fibers, sand, and gravel. The mixing effect of these raw materials directly affects the final quality of the drainage pipe.

[0003] In the production process of reinforced concrete pipes, a mixing device is needed to mix the raw materials. However, existing mixing devices cannot completely scrape off the raw materials adhering to the inner wall of the mixing device during the mixing process, which affects the mixing effect of the raw materials.

[0004] Existing patent (publication number: CN215654751U) discloses a raw material mixing device for the production of reinforced concrete drainage pipes, specifically relating to the technical field of cement product production equipment. This utility model includes a mixing box, a rotating shaft, a first motor, spiral blades, a mixing fork, a mixing rod, a first scraper, a tapping mechanism, a scraper rod, a second scraper, a feed inlet, and a discharge outlet. The mixing forks are staggered between each pitch of the spiral blades, and the mixing is inclined downwards. One end of the mixing fork is fixedly connected to the rotating shaft, and the other end of the mixing fork is connected to the first scraper. The mixing rod is vertically and staggered on the mixing rod. The tapping mechanism is provided on both sides of the outer wall of the mixing box. The scraper rod is connected to both sides of the rotating shaft between the spiral blades and the discharge blades through reinforcing rods. The second scraper is fixedly connected to the bottom of the scraper rod, so as to achieve thorough scraping of the raw materials and ensure the mixing effect of the raw materials.

This results in sedimentation of various concrete raw materials during the mixing process, leading to long mixing times and poor mixing effects.

[0006] Therefore, a hybrid structure for processing raw materials for reinforced concrete drainage pipes is proposed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1 to 5 This utility model provides a technical solution:

[0030] A raw material processing and mixing structure for reinforced concrete drainage pipes includes a mixing tank 1, a drive motor 2 bolted to the top of the mixing tank 1, a stirring shaft 3 connected to the middle bearing of the mixing tank 1, the stirring shaft 3 being fixedly connected to the output end of the drive motor 2, a stirring impeller 4 being provided on the side wall of the stirring shaft 3, a circulating mixing mechanism 5 being provided on the side wall of the mixing tank 1, and a liquid addition assembly 6 being provided on the top of the mixing tank 1.

[0031] The circulating mixing mechanism 5 includes a feeding cylinder 51, a feeding motor 52, a conveying shaft 53, a spiral blade 54, a discharge port 55, a feed hopper 56, and an inclined tube 57. The feeding cylinder 51 is installed on the side wall of the mixing tank 1. The feeding motor 52 is bolted to the top of the feeding cylinder 51. The conveying shaft 53 is fixedly connected to the output end of the feeding motor 52. The conveying shaft 53 is bearing connected to the middle of the feeding cylinder 51. The spiral blade 54 is fixedly connected to the side wall of the conveying shaft 53. The discharge port 55 is located at the top of the feeding cylinder 51 and is connected through the mixing tank 1. The feed hopper 56 is located at the bottom of the feeding cylinder 51. The inclined tube 57 is located at the bottom of the mixing tank 1, and one end of the inclined tube 57 is connected through the feeding cylinder 51.

[0032] Specifically, such as Figure 3 As shown, an electric push rod 7 is bolted to the side wall of the inclined tube 57, and a block 8 is movably installed inside the inclined tube 57. The output end of the electric push rod 7 is fixedly connected to the block 8.

[0033] Specifically, such as Figure 4As shown, a protrusion 9 is provided on the side wall of the feed hopper 56, and a sealing plate 10 is movably provided in the middle of the protrusion 9.

[0034] Specifically, such as Figure 4 As shown, the bottom of the feeding cylinder 51 is provided with a discharge port 11, and a cover 12 is threadedly connected to the side wall of the discharge port 11. A plug 13 is provided inside the cover 12.

[0035] Specifically, such as Figure 1 As shown, four support legs 15 are welded to the outer wall of the mixing tank 1, and reinforcing crossbars 16 are welded to the side walls of the four support legs 15.

[0036] Specifically, such as Figure 1 As shown, the bottom of the mixing tank 1 is inclined, and a vibration motor 17 is bolted to the bottom of the mixing tank 1.

[0037] During operation, the feeding motor 52 is connected to an external power source and starts. Its output shaft drives the conveying shaft 53 to rotate in the forward direction. During rotation, the spiral blade 54 conveys the raw materials entering the feeding cylinder 51 through the feed hopper 56 to the mixing tank 1. After the drive motor 2 starts, it drives the stirring impeller 4 to rotate via the stirring shaft 3, performing preliminary mixing of the raw materials in the mixing tank 1. Then, the electric push rod 7 is controlled to pull the block 8 to move within the inclined tube 57, allowing the raw materials inside the mixing tank 1 to enter the feeding cylinder 51 through the inclined tube 57. The spiral blade 54 then... The raw materials, after initial mixing, are conveyed to the mixing tank 1 for recycling. During the conveying process, the raw materials are mixed again, thus improving the mixing effect and shortening the mixing time. During discharge, the feeding motor 52 drives the conveying shaft 53 to rotate in the reverse direction, and the raw materials are discharged through the discharge port 11. The sealing plate 10 connected to the protrusion 9 of the feed hopper 56 can open or close the feed port. During the mixing process, the vibration motor 17 at the bottom of the mixing tank 1 can effectively prevent the raw materials from sticking to the wall and promote uniform mixing.

[0038] Specifically, such as Figure 5 As shown, the liquid addition assembly 6 includes a ring pipe 61, an infusion pump 62, and infusion holes 63. The ring pipe 61 is installed on the inner wall of the mixing tank 1. The infusion pump 62 is bolted to the top of the mixing tank 1. The output end of the infusion pump 62 is connected to the ring pipe 61. The infusion pump 62 is connected to an external water source. Multiple infusion holes 63 are opened on the side wall of the ring pipe 61.

[0039] Specifically, such as Figure 5 As shown, a swash plate 14 is provided on the inner wall of the mixing tank 1, and the swash plate 14 is located below the annular pipe 61.

[0040] In use, the infusion pump 62 is first connected to an external water source. The infusion pump 62 delivers water evenly to the mixing tank 1 through the ring pipe 61 and the infusion hole 63, so that the raw materials and water are evenly mixed. The inclined plate 14 can protect the ring pipe 61 to prevent the raw materials from splashing onto the ring pipe 61 during the stirring process.

[0041] By adopting the above technical solution, the problem that existing raw material mixing and blending devices for the production of reinforced concrete drainage pipes cannot circulate and mix concrete raw materials, and that various raw materials in concrete will settle during the mixing process, resulting in long mixing time and poor mixing effect of concrete raw materials are solved.

[0042] Working principle: When this application is in use, the feeding motor 52 is first connected to an external power source and started. Its output shaft drives the conveying shaft 53 to rotate in the forward direction. During the rotation, the spiral blade 54 can transport the raw materials that enter the feeding cylinder 51 through the feeding hopper 56 to the mixing tank 1. At the same time, the liquid pump 62 is connected to an external water source. The liquid pump 62 delivers water evenly to the mixing tank 1 through the ring pipe 61 and the liquid inlet 63. After the drive motor 2 is started, the stirring shaft 3 drives the stirring impeller 4 to rotate, which performs preliminary stirring and mixing of the raw materials in the mixing tank 1. Then, the electric push rod 7 is controlled to pull the block 8 to move in the inclined tube 57, so that the raw materials in the mixing tank 1 enter the feeding cylinder 51 through the inclined tube 57. The spiral blade 54 lifts and conveys the raw materials that have undergone preliminary mixing, and circulates the raw materials to the mixing tank 1. The raw materials are mixed again during the conveying process. In this way, the raw materials are circulated and conveyed, which improves the mixing effect of the raw materials and shortens the mixing time.

[0043] 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 the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
