Description

Technical Field

[0001] This utility model belongs to the technical field of high-power mixers, specifically relating to a feeding device for a horizontal high-power mixer. Background Technology

[0002] Horizontal high-intensity mixers are commonly used machines for mixing and stirring solid materials. They have advantages such as high mixing efficiency, high mixing intensity, and uniform mixing, and are widely used in industries such as metallurgy, building materials, sintering, and fertilizer production. During operation, the arrangement of materials in a horizontal high-intensity mixer greatly affects the mixing effect. The mixing mechanism of a horizontal high-intensity mixer typically consists of two to three layers. The outer spiral collects material from both sides towards the center, while the inner spiral conveys the material from the center to the sides, creating more vortices in the material flow, thereby accelerating the mixing speed and improving the mixing uniformity.

[0003] In existing technologies, a feed inlet is typically located at the top of one end of the high-intensity mixer casing, with a chute above the inlet for free-fall material entering the mixer. During material distribution, materials enter the mixer according to their type. When one type of material falls from the feed inlet into the mixer's agitation device and is propelled forward by the mixer's drive system, the subsequent material flow creates a sequential distribution. This results in a considerable time required for multiple materials to achieve a satisfactory mixing effect, leading to low mixing efficiency.

[0004] In addition, the equipment layout of this feeding method is also unreasonable, which increases the equipment installation height and the corresponding plant height, thus increasing construction costs. Because it involves a hydraulic station, the chute needs to be disassembled during the maintenance of the strong mixer, which is troublesome and inconvenient to operate, affecting maintenance efficiency. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this utility model provides a feeding device for a horizontal high-intensity mixer. The feeding port is changed from the top of the high-intensity mixer to the side of the high-intensity mixer, and the feeding method is changed from chute feeding to screw feeding. This effectively reduces the equipment layout height and plant height, and the equipment layout is more reasonable. By changing the feeding method, the distribution of materials during feeding is improved, thereby increasing the mixing efficiency of the high-intensity mixer.

[0006] The technical solution adopted by this utility model is as follows: a feeding device for a horizontal high-strength mixer. The horizontal high-strength mixer is fixedly installed on the frame. A side feed port parallel to the ground is opened on the side of one end of the high-strength mixer cylinder. A discharge port is opened at the bottom of the other end of the high-strength mixer cylinder. The side feed port is connected to the outlet end of a screw feeder. A drive motor reducer is connected to the inlet side end of the screw feeder. A support is provided at the bottom of the inlet end of the screw feeder. An upper feed port is opened near the upper right end of the pipe shell of the screw feeder. The motor reducer is fixed on the mounting base. Both the support and the mounting base are fixedly installed on the frame.

[0007] The screw feeder includes a hollow conveying pipe, a screw shaft passing through the housing of the conveying pipe and arranged co-centered therewith, screw blades fixedly provided on the outside of the screw shaft, a bearing and bearing seat fixedly provided at the power input end of the screw shaft, and a suspension bearing provided at the other end of the screw shaft, which is fixedly installed on the inner wall of the conveying pipe; the power input end of the screw shaft is connected to the output shaft of the drive motor reducer through a coupling.

[0008] The centerline of the side feed inlet is set parallel to the main shaft of the high-intensity mixer, and the outlet end of the screw feeder's conveying pipe is sealed and fixed inside the side feed inlet of the high-intensity mixer by a flange.

[0009] The screw feeder is a horizontal tubular screw feeder. The screw diameter is determined to be 200-400mm and the speed is 50-200rpm, which is matched with the processing speed of the high-intensity mixer.

[0010] The diameter of the side feed inlet is ≥1.5 times the diameter of the spiral blade, and the inner wall of the side feed inlet is lined with high molecular weight polyethylene or ceramic wear-resistant lining.

[0011] The screw feeder is equipped with a separate motor reducer, and the drive motor is a variable frequency speed control motor, which facilitates the adjustment of the feeding amount. The screw feeder is linked with the high-intensity mixer for control. When the high-intensity mixer stops, the screw feeder stops automatically to prevent material blockage.

[0012] The side feed inlet is connected to the outlet end of the screw feeder, and a drive motor reducer is connected to the inlet end of the screw feeder. A support is provided at the bottom of the inlet end of the screw feeder. The purpose of this arrangement is that the support at the end of the conveying pipe of the screw feeder can achieve a good stabilizing and fixing effect. The tubular structure of the conveying pipe is tightly sealed and does not easily spill materials, which can realize stable conveying of side screw feeding. Compared with the chute feeding method, different materials are pre-mixed in the screw feeder, which prolongs the mixing time and improves the mixing efficiency of the strong mixer.

[0013] The screw feeder includes a hollow conveying pipe, a screw shaft passing through the housing of the conveying pipe and co-centered therewith, screw blades fixedly mounted on the outside of the screw shaft, a bearing and bearing seat fixedly mounted at the power input end of the screw shaft, and a suspension bearing fixedly mounted on the inner wall of the conveying pipe at the other end of the screw shaft. The power input end of the screw shaft is connected to the output shaft of the drive motor reducer via a coupling. The purpose of this configuration is that the screw feeder is a device that uses rotating screw blades to push and convey materials. The force preventing the material from rotating with the blades is its own weight and the frictional resistance of the housing against the material. The screw blades are welded and fixed to the screw shaft of the screw feeder, and the screw shaft and screw blades play the most important conveying role, better promoting the flowability and pushing force of the material. A horizontal tubular screw feeder is adopted, with a simple main structure, suitable for short-distance (<5m) feeding. A separate motor reducer is configured to adjust the material conveying speed and conveying capacity. The screw diameter and rotation speed are determined according to the material processing capacity to match the processing speed of the strong mixer, avoiding overload operation.

[0014] The beneficial effects of this utility model are as follows: The feeding device is scientifically and rationally designed and has a simple structure. The feeding method of the high-strength mixer is changed from chute feeding to screw feeding. The material is transported into the high-strength mixer by the screw feeder, which effectively reduces the equipment layout height and plant height, and the equipment layout is more reasonable. By changing the feeding method, the distribution state of the material when the high-strength mixer is fed is improved, thereby improving the mixing efficiency of the high-strength mixer.

[0017] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0018] like Figure 1As shown, in the prior art, a feed inlet 13 is provided at the upper position of one end of the shell of the high-strength mixer 2, and a chute 14 is provided above the feed inlet 13. The material enters the interior of the high-strength mixer 2 from the chute 14 by free falling. The material inside is strongly stirred and pushed by the rake teeth on the drive shaft. The mixed material moves towards the discharge port 4 under the pushing action of the rake teeth and is finally discharged from the discharge port 4, completing the entire material mixing process.

[0019] like Figure 2-4 As shown, a feeding device for a horizontal high-intensity mixer is provided. The horizontal high-intensity mixer 2 is fixedly installed on the frame 1. A side feed port 3 parallel to the ground is opened on the side of one end of the cylinder of the high-intensity mixer 2, and a discharge port 4 is opened at the bottom of the other end of the cylinder of the high-intensity mixer 2. The side feed port 3 is connected to the outlet end of the screw feeder 5. A drive motor reducer 8 is connected to the inlet side end of the screw feeder 5. A support 7 is provided at the bottom of the inlet end of the screw feeder 5. An upper feed port 6 is opened on the upper right end of the pipe shell of the screw feeder 5. The motor reducer 8 is fixed on the mounting base 9. Both the support 7 and the mounting base 9 are fixedly installed on the frame.

[0020] The screw feeder 5 includes a hollow conveying pipe, a screw shaft 10 passing through the housing of the conveying pipe and arranged co-centered therewith, screw blades fixedly provided on the outside of the screw shaft 10, a bearing 11 and a bearing seat fixedly provided at the power input end of the screw shaft 10, and a suspension bearing 12 provided at the other end of the screw shaft 10, with the suspension arm of the suspension bearing 12 welded and fixed to the upper part of the inner wall of the conveying pipe; the power input end of the screw shaft 10 is connected to the output shaft of the drive motor reducer 8 through a coupling.

[0021] The centerline of the side feed inlet 3 is set parallel to the main shaft of the high-intensity mixer 2. The outlet end of the conveying pipe of the screw feeder 5 is sealed and fixed inside the side feed inlet 3 of the high-intensity mixer 2 by a flange. The material is pushed by the screw shaft and the screw blades, and smoothly enters the high-intensity mixer 2 from the outlet end of the conveying pipe.

[0022] The screw feeder 5 is a horizontal tubular screw feeder 5. The screw diameter is determined to be 200-400mm and the speed is 50-200rpm according to the material processing capacity, which matches the processing speed of the high-strength mixer 2.

[0023] The diameter of the side feed port 3 is ≥ 1.5 times the diameter of the spiral blade, and the inner wall of the side feed port 3 is lined with high molecular weight polyethylene or ceramic wear-resistant lining plate; a quick-opening door (not shown in the figure) can be opened on the side of the side feed port 3 to facilitate cleaning of material blockage.

[0024] The screw feeder 5 is equipped with a separate motor reducer 8, and the drive motor is a variable frequency speed control motor, which is convenient for adjusting the feeding amount. The screw feeder 5 is linked with the high-pressure mixer 2 for control. When the high-pressure mixer 2 stops, the screw feeder 5 automatically stops to prevent material blockage.

[0025] The screw shaft 10 of the screw conveyor 5 is provided with a thrust bearing at the end of the material movement direction to counteract the axial reaction force of the material on the screw shaft 10. When the conveying pipe of the screw conveyor 5 is long, an intermediate suspension bearing 12 can be added.

[0026] When the high-intensity mixer 2 is working, the screw feeder 5 is started first. When the screw feeder 5 feeds, the material is put into the upper feed port 6 of the screw feeder 5. The drive motor reducer 8 drives the screw shaft 10 of the screw feeder 5 to rotate. The speed of the screw shaft 10 is adjusted according to the material conveying volume. The material is pushed forward by the rotation of the screw shaft 10 and reaches the conveying pipe of the screw feeder 5 and the side feed port 3 of the high-intensity mixer 2. The material is conveyed into the high-intensity mixer 2 through the discharge port 12. After the various materials are mixed evenly in the high-intensity mixer 2, they are discharged through the discharge port 4. When the high-intensity mixer 2 stops working, the screw feeder 5 is stopped first to prevent the material from accumulating. The feeding device is scientifically and rationally designed with a simple structure. It changes the feeding method of the high-intensity mixer 2 from chute feeding to screw feeding. The screw feeder 5 premixes the materials and then conveys them into the high-intensity mixer 2, which effectively reduces the equipment layout height and plant height, and makes the equipment layout more reasonable. By changing the feeding method, the material distribution of the high-intensity mixer 2 is improved, thereby increasing the mixing efficiency of the high-intensity mixer.
