Description
Technical Field
[0001] This utility model relates to the technical field of mixing devices, specifically a mixing device for producing blended materials. Background Technology
[0002] Blended materials are widely used in many industries such as construction and chemical industry. During the production process, the uniformity of material mixing directly affects the final performance of the blended material. Therefore, the mixing device is one of the core equipment in the blended material production line. It is used to fully mix various raw materials in a certain proportion to meet the needs of subsequent processing and application.
[0003] Existing mixing devices for admixture production mostly adopt a single mixing structure, using only a single mixing component to mix materials. This structural design makes it easy for materials to accumulate locally and for mixing to be incomplete during the mixing process. At the same time, the lack of a segmented mixing process design makes it difficult to ensure the uniformity of cement mixing. Furthermore, some devices require a lot of manual intervention to assist in completing the material conveying and mixing process, which in turn affects the mixing efficiency of admixture production. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a mixing device for admixture production, which solves the problems mentioned in the background art, such as the difficulty in ensuring the uniformity of cement mixing and the need for considerable manual intervention in some devices to assist in the material conveying and mixing process, thereby affecting the mixing efficiency of admixture production.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a mixing device for producing admixtures, comprising:
[0006] A base, an mounting plate is installed on the upper surface of the base, a mixing cylinder is provided above the base, a first motor is installed on the surface of the mounting plate, and an auger is installed through the rotor of the first motor through the surface of the mixing cylinder.
[0007] The second motor is located on the upper surface of the mixing cylinder, and the rotor of the second motor is coaxially mounted with gears.
[0008] A rotating drum is disposed inside a mixing drum, and a rack is mounted on the surface of the rotating drum, wherein the gear meshes with the surface of the rack;
[0009] A conveying pipe is provided at the outlet of the mixing cylinder. A mixing cylinder is installed on the upper surface of the base, and the outlet of the conveying pipe is connected to the inlet of the mixing cylinder.
[0010] Preferably, a third motor is installed on the upper surface of the mixing drum. The rotor of the third motor passes through the upper surface of the mixing drum and is equipped with a rotating rod. The surface of the rotating rod is evenly distributed with stirring rods. Starting the third motor can drive the rotating rod to rotate, thereby driving the stirring rod to rotate and remix the incoming cement raw materials.
[0011] Preferably, a scraper is installed on the surface of the stirring rod, and a discharge pipe is installed at the discharge port of the mixing cylinder. The edge of the scraper is designed to be a smooth arc shape, which can avoid scratching the inner wall when scraping the residual material on the inner wall of the mixing cylinder.
[0012] Preferably, a valve is installed on the surface of the discharge pipe, and the lower part of the inner cavity of the mixing cylinder is designed in a funnel shape. The valve's sealing structure adopts a multi-layer sealing ring design, which can effectively prevent material leakage during the discharge process. The funnel shape design helps the material to converge more smoothly at the discharge pipe, improving the discharge efficiency.
[0013] Preferably, a limiting ring is installed on the surface of the rotating cylinder, and a limiting track is installed on the inner wall of the mixing cylinder at a position corresponding to the limiting ring. The limiting ring and the limiting track can ensure that the rotating cylinder can rotate smoothly inside the mixing cylinder.
[0014] Preferably, sliding rails are installed on both sides of the inner cavity of the mixing cylinder, and the sliding rails are connected to the interface of the rotating cylinder to seal the interface of the mixing cylinder.
[0015] Preferably, a support plate is installed on the upper surface of the base, and a buffer pad is installed on the upper surface of the support plate. The buffer pad is connected to the bottom of the mixing cylinder, and the buffer pad can effectively absorb the vibration generated by the mixing cylinder during operation.
[0016] Preferably, the mixing cylinder has a feed pipe installed at its inlet. The feed pipe has a funnel-shaped inlet and its inner wall is polished, which makes the material flow more smoothly into the mixing cylinder and prevents blockage. The funnel-shaped design also increases the area of the feed inlet, making it easier for operators to quickly pour the material into the mixing cylinder.
[0017] Compared with the prior art, the present invention provides a mixing device for the production of admixtures, which has the following beneficial effects:
[0018] This mixing device for admixture production features a first motor that drives an auger within the mixing drum, achieving both material conveying and initial mixing. Simultaneously, a second motor drives a gear, which, through meshing with a rack on the rotating drum surface, causes the drum to rotate synchronously inside the mixing drum, creating a dual mixing effect with the auger. This effectively improves the uniformity of cement mixing and avoids the problem of insufficient mixing caused by a single mixing structure. The pre-mixed material in the mixing drum is then conveyed to the final mixing drum via a conveying pipe, achieving a segmented mixing process and ensuring the orderly progress of the mixing process. The overall structure, through motor-driven mechanical transmission, reduces manual intervention during the material mixing process and improves the mixing efficiency of admixture production.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0025] This utility model provides a technical solution: a mixing device for producing admixtures. Please refer to [link / reference]. Figure 1 It includes a base 1, an mounting plate 2 mounted on the upper surface of the base 1, a mixing cylinder 3 located above the base 1, and a first motor 4 mounted on the surface of the mounting plate 2. Please refer to [link / reference]. Figure 2 The rotor of the first motor 4 is mounted with an auger 5 through the surface of the mixing cylinder 3;
[0026] The second motor 6 is located on the upper surface of the mixing cylinder 3, and the rotor of the second motor 6 is coaxially mounted with a gear 7.
[0027] Rotating cylinder 8 is located inside mixing cylinder 3. Please refer to [link / reference]. Figure 3 A rack 9 is mounted on the surface of the rotating cylinder 8, and the gear 7 meshes with the surface of the rack 9;
[0028] Please see Figure 2 The conveying pipe 10 is located at the outlet of the mixing cylinder 3. Please refer to [link / reference]. Figure 1 A mixing cylinder 11 is installed on the upper surface of the base 1, and the outlet of the conveying pipe 10 is connected to the inlet of the mixing cylinder 11.
[0029] The base 1 provides a stable mounting foundation for the first motor 4 via the mounting plate 2. The first motor 4 drives the auger 5 to operate inside the mixing cylinder 3, which can both convey materials and complete the initial mixing. At the same time, the second motor 6 drives the gear 7 to rotate. Through the meshing transmission between the gear 7 and the rack 9 on the surface of the rotating cylinder 8, the rotating cylinder 8 rotates synchronously inside the mixing cylinder 3, forming a double mixing effect with the auger 5. This effectively improves the uniformity of material mixing and avoids the problem of insufficient mixing caused by a single mixing structure. The material initially mixed in the mixing cylinder 3 is accurately conveyed to the mixing cylinder 11 through the conveying pipe 10, realizing a segmented mixing process and ensuring the orderly progress of the mixing process. The overall structure reduces manual intervention in the material mixing process through the mechanical transmission driven by the motor, improves the mixing efficiency of the admixture production, and ensures the continuity and reliability of the material in the transmission and mixing process by installing each component stably.
[0030] Please see Figure 4 A third motor 12 is installed on the upper surface of the mixing drum 11. The rotor of the third motor 12 passes through the upper surface of the mixing drum 11 and a rotating rod 13 is installed. A stirring rod 14 is evenly distributed on the surface of the rotating rod 13. Starting the third motor 12 can drive the rotating rod 13 to rotate, thereby driving the stirring rod 14 to rotate and mix the incoming cement raw materials again.
[0031] A scraper 15 is installed on the surface of the stirring rod 14, and a discharge pipe 16 is installed at the discharge port of the mixing cylinder 11. The edge of the scraper 15 is designed to be a smooth arc shape, which can prevent the inner wall from being scratched when scraping the residual material on the inner wall of the mixing cylinder 11.
[0032] A valve is installed on the surface of the discharge pipe 16. The lower part of the inner cavity of the mixing cylinder 11 is designed in the shape of a funnel. The valve sealing structure adopts a multi-layer sealing ring design, which can effectively prevent material leakage during the discharge process. The funnel-shaped design helps the material to converge more smoothly at the discharge pipe 16, thereby improving the discharge efficiency.
[0033] Please see Figure 3A limit ring 17 is installed on the surface of the rotating cylinder 8. Please refer to [link / reference]. Figure 2 The inner wall of the mixing cylinder 3 is equipped with a limiting track 18 at the corresponding position of the limiting ring 17. The limiting ring 17 and the limiting track 18 can ensure that the rotating cylinder 8 can rotate smoothly inside the mixing cylinder 3.
[0034] Sliding rails 19 are installed on both sides of the inner cavity of the mixing cylinder 3. The sliding rails 19 are connected to the interface of the rotating cylinder 8, which can seal the interface of the mixing cylinder 3.
[0035] Please see Figure 1 A support plate 20 is mounted on the upper surface of the base 1. Please refer to [link / reference]. Figure 2 A buffer pad 21 is installed on the upper surface of the support plate 20. The buffer pad 21 is connected to the bottom of the mixing cylinder 3. The buffer pad 21 can effectively absorb the vibration generated by the mixing cylinder 3 during operation.
[0036] Please see Figure 1 The mixing cylinder 3 is equipped with a feed pipe 22 at its inlet. The feed pipe 22 has a funnel-shaped inlet and its inner wall is polished, which makes the material flow more smoothly into the mixing cylinder 3 and prevents blockage. The funnel-shaped design increases the area of the feed inlet, making it easier for operators to quickly pour the material into the mixing cylinder 3.
[0037] In this design, the material smoothly enters the mixing cylinder 3 through the funnel-shaped feed pipe 22 with a polished inner wall. The base 1 provides stable support for the first motor 4 through the mounting plate 2. The first motor 4 drives the auger 5 to operate, realizing material conveying and preliminary mixing. At the same time, the second motor 6 drives the gear 7 to rotate, which meshes with the rack 9 on the surface of the rotating cylinder 8, so that the rotating cylinder 8 rotates synchronously in the mixing cylinder 3 under the cooperation of the limiting ring 17 and the limiting track 18 and the sealing interface of the sliding track 19, forming a double mixing with the auger 5 to improve the mixing uniformity. After preliminary mixing, the material is conveyed to the mixing cylinder 11 through the conveying pipe 10. The third motor 12 drives the rotating rod 13 and the stirring rods 14 and scraper 15 on the surface to rotate, mixing the material again. The smooth arc edge of the scraper 15 avoids scratching the inner wall of the mixing cylinder 11. After mixing, the material is smoothly discharged from the mixing cylinder 11 in the funnel-shaped inner cavity through the discharge pipe 16 controlled by the valve, and the buffer pad 21 on the support plate 20 effectively absorbs the working vibration of the mixing cylinder 3.
