Description

Technical Field

[0001] This utility model relates to the field of mixing and agitating machine technology, and in particular to an online mixing and agitating machine for belt conveyor chutes. Background Technology

[0002] Coking coal production involves feeding various types of coal with different coking properties into the coal blending trough in the coal preparation section, where they are fed into the blending trough by a conveyor belt in a certain proportion. The coal is then transported to a crusher for crushing, and finally fed onto the coal tower via a conveyor belt. During this process, different types of coal can only be stacked onto the conveyor belt in the order they are fed by the disc feeder at the bottom of the blending trough; the mixing and stirring are handled by the crusher.

[0003] However, the mixing effect of different types of coal is limited by the mixing capacity of the pulverizer. The limited mixing effect of the pulverizer results in insufficient and uneven mixing of different types of coal, leading to inhomogeneity in coal quality. This uneven mixing directly affects the quality of the blended coal, which may result in significant differences in the coking properties of the final coke product. Summary of the Invention

[0016] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0017] Please see Figure 1-7 This utility model provides an online mixing and agitator for a belt conveyor chute, including a mixing mechanism installed on the side wall of the belt conveyor chute 1, and the mixing mechanism is installed below the belt conveyor head pulley 20; The mixing mechanism includes a drive motor 2, a bearing housing 3, a main housing 6, and multiple sets of stirring blades 7. The output end of the drive motor 2 is connected to an output shaft 21 via a coupling. A bushing 4 is detachably connected to the side of the bearing housing 3 away from the drive motor 2, and a fixing sleeve 5 is detachably connected to the side of the bushing 4 away from the bearing housing 3. The output shaft 21 passes through the bearing housing 3, the bushing 4, and the fixing sleeve 5 in sequence. The drive motor 2 and the bearing housing 3 are supported by a support frame 23 fixedly connected to the outer wall of the belt conveyor chute 1. The side wall of the belt conveyor chute 1 has a through-hole for mounting, and the fixing sleeve 5 is fixedly connected to the mounting... Inside the hole, the main housing 6 is located inside the belt conveyor chute 1, and the end of the fixing sleeve 5 away from the bushing 4 extends into the interior of the main housing 6. The end of the output shaft 21 away from the drive motor 2 extends to the outside of the fixing sleeve 5 and is detachably connected to the main housing 6. Multiple sets of stirring blades 7 are circumferentially and equidistantly installed on the side of the main housing 6, and each set of stirring blades 7 is parallel to the output shaft 21. The interior of the main housing 6 is connected to a drive component 8 for driving the rotation of multiple sets of stirring blades 7. The center of the side of the main housing 6 is detachably connected to an auxiliary support component 9 for supporting the ends of multiple sets of stirring blades 7.

[0018] Specifically, flange 41 and flange 42 are fixedly fitted at both ends of the bushing 4, respectively. Flange 41 is used to connect the bushing 4 to the bearing housing 3 by bolts, and flange 42 is used to connect the bushing 4 to the fixed sleeve 5 by bolts. Furthermore, multiple sets of bearings 31 are fixedly installed inside the bearing housing 3 to provide rotational support for the rotation of the output shaft 21.

[0019] This invention, by installing a mixing mechanism inside the conveyor belt chute 1, enables the material to be mixed and stirred simultaneously as it flows from the conveyor belt into the chute 1. This design effectively compensates for the shortcomings of traditional crushers in terms of mixing capacity, allowing for more uniform mixing of different types of coal, thereby improving the uniformity of coal quality and the overall blending quality. Furthermore, compared to traditional separate mixing chambers, this device offers higher efficiency, enabling simultaneous material mixing and conveying, avoiding the cumbersome and space-wasting nature of additional mixing chambers.

[0020] Specifically, the drive motor 2 is started, and the drive motor 2 drives the output shaft 21 to rotate via the coupling. The output shaft 21 then drives the main housing 6 and the multiple sets of stirring blades 7 installed on the side to rotate in a large circumferential direction, thereby agitating the material over a large area within the conveyor belt chute 1. At the same time, under the action of the drive component 8, each set of stirring blades 7 also rotates around its own axis. This dual rotation effectively enhances the intensity and uniformity of the mixing, greatly improving the uniformity of coal mixing and resulting in a significant improvement in the final coal blending quality.

[0021] Furthermore, the drive motor 2 preferably employs a cycloidal pinwheel reducer. This type of reducer can provide high output torque, reduce the workload of the motor, and ensure the stability of the system during long-term operation, adapting to high-load work under complex conditions. Furthermore, the main housing 6 includes a front cover 61, a rear cover 62, and a side cover 63 connected between the front cover 61 and the rear cover 62. The front cover 61 is located at the end away from the drive motor 2, and the rear cover 62 is located at the end close to the drive motor 2. A central hole 621 for accommodating a fixed sleeve 5 extending into the interior of the main housing 6 is provided through the center of the rear cover 62. A fixed plate 22 is fixedly connected to the end of the output shaft 21 away from the drive motor 2. The fixed plate 22 is detachably fixedly connected to the inner sidewall of the front cover 61 by bolts.

[0022] Specifically, the front cover 61 and the rear cover 62 are fixed to the front and rear sides of the side shell 63 by bolts, which facilitates daily maintenance and repair.

[0023] Furthermore, the drive component 8 includes an internal gear 81 and multiple sets of side gears 82 corresponding one-to-one with the stirring blades 7. The center position of the internal gear 81 near the drive motor 2 is fixedly connected to the fixed sleeve 5. The multiple sets of side gears 82 are arranged in a ring around the circumferential outer side of the internal gear 81 and mesh with each other. A shaft 83 is fixedly installed through the center of the side gear 82. The end of the shaft 83 near the drive motor 2 is rotatably connected to the rear cover 62, and the end of the shaft 83 away from the drive motor 2 rotatably passes through the front cover 61 and is detachably connected to the stirring blades 7 at the corresponding positions.

[0024] Specifically, the internal gear 81 is connected to the completely stationary conveyor chute 1 via a fixed sleeve 5. This ensures that when the output shaft 21 drives the main housing 6 to rotate circumferentially, the internal gear 81 itself does not rotate. Simultaneously, multiple sets of side gears 82 surrounding the outer side of the internal gear 81 rotate around the output shaft 21 along with the main housing 6, driven by the main housing 6. Due to the meshing between the side gears 82 and the internal gear 81, the side gears 82 rotate on their own shafts 83 while rotating, greatly enhancing the mixing effect and material handling efficiency, ensuring thorough mixing of different coal types.

[0025] Furthermore, the stirring blade 7 includes a stirring shaft 71, and multiple sets of blades 72 are fixedly mounted circumferentially on the outer side of the stirring shaft 71. A flange 3 73 is fixedly sleeved on the outer side of one end of the stirring shaft 71 near the shaft 83, and a flange 4 84 is fixedly sleeved on the outer side of the other end of the shaft 83. The flange 3 73 and the flange 4 84 are fixed together by bolts.

[0026] Specifically, since the agitator blade 7 is a wear part, the agitator shaft 71 and the shaft 83 are designed to be detachably connected, which greatly improves the efficiency of disassembly and assembly for later maintenance. When it is necessary to remove the agitator blade 7, simply remove the bolts from flange three 73 and flange four 84 for quick disassembly.

[0027] Furthermore, a plug rod 74 is fixedly connected to one end of the stirring shaft 71 near the shaft rod 83. The shaft rod 83 near the stirring shaft 71 has a plug hole 831 that is inserted into the plug rod 74. Multiple sets of positioning ribs 741 are fixedly fixed in an annular pattern on the outer side of the plug rod 74. Multiple sets of positioning grooves 832 that are inserted into the positioning ribs 741 are formed in an annular pattern on the inner side wall of the plug hole 831.

[0028] Specifically, in addition to the mutual fixing of flange three 73 and flange four 84, the stirring shaft 71 and the shaft 83 are also fixed by the insertion of the insert rod 74 into the insertion hole 831. This makes the structure of the stirring shaft 71 and the shaft 83 more stable after they are fixed, thus effectively withstanding the impact force of materials falling onto the stirring blade 7. Secondly, through the mutual cooperation of the positioning rib 741 and the positioning groove 832, the insert rod 74 can be quickly and accurately positioned when inserted into the insertion hole 831. This not only improves the assembly efficiency but also ensures the accuracy of the connection position.

[0029] Furthermore, the auxiliary support component 9 includes a central column 91 and multiple sets of support arms 93 corresponding one-to-one with the stirring blades 7. A flange 92 is fixedly sleeved on the outer side of the end of the central column 91 near the main housing 6. The flange 92 is fixedly connected to the center position of the outer side wall of the front cover 61 by bolts. Multiple sets of support arms 93 are equidistantly fixed in a ring on the outer side of the end of the central column 91 away from the flange 92. A fixing plate 94 is fixedly connected to the end of the support arm 93 away from the central column 91. A support seat 75 is rotatably sleeved on the outer side of the end of the stirring shaft 71 away from the shaft rod 83. The support seat 75 and the corresponding fixing plate 94 are detachably fixedly connected by bolts.

[0030] Specifically, the stirring shaft 71 extends from the main housing 6, forming a relatively long cantilever beam. Under stirring resistance, its end will experience significant bending and vibration, thereby increasing the risk of damage to the stirring blade 7. This invention, by providing an auxiliary support 9, can provide a robust support point for the end of the stirring blade 7, greatly enhancing overall rigidity and ensuring stable operation of the equipment. Secondly, the support base 75 is rotatably connected to the stirring shaft 71, so that even while providing support, the rotation of the stirring shaft 71 is not affected.

[0031] Furthermore, a baffle seat 10 is fixedly connected to the inner wall of the belt conveyor chute 1 and above the main housing 6. The baffle seat 10 is an inclined seat, which can guide the material falling on it to the area on the stirring blade 7.

[0032] Specifically, the baffle seat 10 ensures that when material falls from the belt conveyor into the belt conveyor chute 1, the material falling onto the baffle seat 10 will be guided to the mixing blade 7 area for full mixing under the slope action of the baffle seat 10, thereby preventing the material from falling directly onto the main housing 6.

[0033] It should be noted that this equipment can be applied to different types of belt conveyor chutes to achieve synchronous mixing and stirring during the material's descent. In practical applications, it can be modified on a small scale based on the existing equipment without changing the original production process and technology, making it more versatile.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
