Description

Technical Field

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

[0002] In the process of mineral resource mining and processing, high-intensity mixers are typically used to efficiently mix various minerals, additives, cement, fly ash, and other materials to improve the mixing uniformity. Horizontal high-intensity mixers for mining are widely used in industries such as mining, metallurgy, and building materials. Their structure generally includes a horizontally arranged cylinder, a drive shaft inside the cylinder, and multiple mixing tools distributed on the drive shaft. The rotation of the shaft drives the mixing tools to shear, tumble, and mix the materials inside the cylinder, resulting in high mixing intensity and high mixing uniformity.

[0003] However, existing horizontal high-intensity mixers for mining still have some shortcomings in use, affecting their durability and operational flexibility. Firstly, the mixing tools inside the drum are in prolonged contact and collision with the material during high-speed mixing, making them prone to wear, shortening their service life, increasing maintenance frequency, and causing long downtime. Secondly, the feed inlet of existing horizontal mixers is located at the top of the drum, and during the material drop process, the material can easily hit the drive shaft inside the drum directly, causing excessive instantaneous stress on the drive shaft and bearings, posing a risk of damage. At the same time, the size of the feed inlet is usually a fixed structure, which cannot be flexibly adjusted according to actual needs, making it difficult to effectively control the feeding speed and the amount of material fed per unit time, affecting the mixing uniformity and production efficiency. Utility Model Content

[0026] 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.

[0027] As shown in the figure, a horizontal high-power mixer for mining includes a horizontally arranged cylinder 1 fixedly mounted. A feed inlet 2 is located at one upper end of the cylinder 1, and a discharge outlet 10 is located on the other lower side of the cylinder 1. A rotatable drive shaft 11 is installed at the center of the cylinder 1. Multiple mixing tools 12 are distributed on the drive shaft 11. Each mixing tool 12 includes inclined rake teeth 1203 located near the inner wall of the cylinder 1. Alloy layers 1205 are provided on both sides of the mixing tools 12 and on both sides of the rake teeth 1203. The alloy layers 1205 are brazed to the surface of the rake teeth 1203 to enhance their wear resistance. The mixing tools 12 are located inside the feed inlet 2 and located on the drive shaft 11. Two hinged movable plates 14 are installed at the top. An adjustment mechanism for adjusting the angle between the two movable plates 14 is provided below the movable plates 14. Specifically, the two movable plates 14 are connected by hinges, and the hinge shaft is fixed to both ends of the feed inlet 2, so that the two movable plates 14 can rotate around the axis of the hinge shaft. The two movable plates 14 are arranged along the width of the inner cavity of the feed inlet 2. During the angle adjustment of the two movable plates 14, the vertical gap of the feed inlet 2 can be changed, thereby adjusting the amount of feed during feeding. In addition, since the two movable plates 14 are located directly above the drive shaft 11, they can prevent the material from directly hitting the drive shaft 11, thus protecting the drive shaft 11.

[0028] The adjustment mechanism includes a V-shaped support rod 16 installed below the movable plate 14. A rotatable rotating rod 15 is installed inside the feed inlet 2. Two drive blocks 18 that can move towards or away from each other are installed on the rotating rod 15. The drive blocks 18 are slidably engaged with the support rod 16. When the drive blocks 18 move, they drive the two movable plates 14 to adjust their angles. The support rod 16 is designed in a V-shape so that it can be pushed or pulled up and down during the horizontal movement of the drive blocks 18, thereby adjusting the angle of the movable plate 14.

[0029] The outer diameters of both ends of the rotating rod 15 are respectively provided with external threads 1501 with opposite directions of rotation. Two drive blocks 18 are respectively threaded to the external threads 1501 of the rotating rod 15. A protrusion 1502 is provided on the rotating rod 15 between the two external threads 1501 to axially limit the drive blocks 18. The drive blocks 18 have first guide holes 1801 on both sides. The support rods 16 under the two movable plates 14 pass through the first guide holes 1801 respectively. By controlling the rotation of the rotating rod 15, and combined with the structure of the external threads 1501 with opposite directions of rotation, the two drive blocks 18 can be driven to move towards or away from each other when the rotating rod 15 rotates. It has the advantages of ingenious structure and good support and adjustment effect for the movable plates 14.

[0030] The drive block 18 is provided with second guide holes 1802 on both sides. A guide rod 19 is installed in the feed port 2. The guide rod 19 passes through the second guide hole 1802 and slides with the drive block 18. The purpose of this arrangement is to ensure that the drive block 18 always moves along the axis of the rotating rod 15, so as to prevent the rotating rod 15 from driving the drive block 18 to rotate during the rotation process, thus achieving a guiding effect.

[0031] One end of the rotating rod 15 passes through the side wall of the feed inlet 2 and is connected to a handwheel 17. In actual operation, the angle of the movable plate 14 can be adjusted by rotating the external handwheel 17. It is understood that in other embodiments, an electric motor can also be connected to the end of the rotating rod 15 to achieve angle adjustment by electric drive.

[0032] The mixing tool 12 also includes a fixed base 1201 installed on the outer wall of the drive shaft 11. The fixed base 1201 has two detachable connecting rods 1202 extending radially along the drive shaft 11. Rake teeth 1203 are fixed to the ends of the connecting rods 1202. A tooth groove 1204 is provided on one side of the rake teeth 1203. The connecting rods 1202 are fixed to the fixed base 1201 by bolt connection to facilitate replacement after the rake teeth 1203 are damaged. The rake teeth 1203 and the connecting rods 1202 are fixed by welding, which has the advantages of stable connection structure and high strength. The rake teeth 1203 are inclined at the ends of the connecting rods 1202, and the inclined direction is towards the discharge port 10. This can both mix and stir the materials and drive the materials to move towards the discharge port 10 to complete the discharge action.

[0033] The cylinder 1 includes a lower cylinder 102 fixedly disposed below and an upper cylinder 101 installed above the lower cylinder 102. The feed inlet 2 is located on one side above the upper cylinder 101, and the discharge outlet 10 is located below the lower cylinder 102. Observation windows 3 are provided on both the lower cylinder 102 and the upper cylinder 101. The upper cylinder 101 and the lower cylinder 102 are connected by bolts to facilitate disassembly and maintenance. The observation windows 3 allow staff to easily observe the internal stirring conditions of the cylinder 1.

[0034] Support seats 9 are provided at both ends of the cylinder 1. Bearing seats 4 are installed on the support seats 9. Both ends of the transmission shaft 11 are installed on the bearing seats 4 through bearings. One end of the transmission shaft 11 passes through the bearing seat 4 and is connected to a drive assembly. The drive assembly mainly includes a fixed base 8. A motor 7 is installed on the base 8. The shaft end of the motor 7 is connected to a reducer 6. The output shaft of the reducer 6 is connected to the transmission shaft 11 through a coupling 5 (or a hydraulic coupling) to realize the transmission of power.

[0035] A baffle plate 13 is installed on the drive shaft 11 inside the cylinder 1. The baffle plate 13 is installed on the drive shaft 11 near the discharge port 10, specifically on the drive shaft 11 between the discharge port 10 and the end wall of the cylinder 1. The baffle plate 13 can block the material.

[0036] When this horizontal high-power mixer for mining is in operation, the motor 7 drives the reducer 6 to rotate the drive shaft 11. The rake teeth 1203 on the drive shaft 11 rotate accordingly, powerfully stirring and pushing the material inside the cylinder 1. The surface of the rake teeth 1203 is provided with a wear-resistant alloy layer 1205, which can effectively improve its wear resistance and extend its service life. The material is added from the feed port 2. During the feeding process, the two movable plates 14 located directly above the drive shaft 11 play a buffering and adjusting role, preventing the material from directly hitting the drive shaft 11. At the same time, the angle of the movable plates 14 can be adjusted by turning the handwheel 17, thereby controlling the feed rate. The mixed material gradually moves towards the discharge port 10 under the pushing action of the rake teeth 1203. The baffle plate 13 near the discharge end can play a role in material isolation and guidance, so that the material is finally discharged from the storage bin, completing the entire mixing process.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
