Description

Technical Field

[0001] This utility model relates to the technical field of a modular raw coal bunker bottom unblocking component, and in particular to a raw coal bunker unblocking device that is easy to maintain. Background Technology

[0002] When storing raw coal in industrial production, blockages often occur in raw coal silos due to factors such as the semi-top angle of the inner wall of the silo, the cross-sectional shrinkage rate, the silo outlet size, and the type and composition of the coal. When the raw coal silo is blocked, production is often forced to stop, affecting the normal operation of equipment, causing various losses to the enterprise, and also posing various safety hazards.

[0003] The current modular raw coal bunker bottom unblocking components have poor unblocking efficiency during use, and are not easy to repair when a fault occurs, which reduces their practicality.

[0004] To address the aforementioned issues, this application proposes a modular raw coal bunker bottom unblocking component that facilitates maintenance. Utility Model Content

Detailed Implementation

[0021] The following description, in conjunction with the accompanying drawings, details the implementation methods and embodiments of this utility model and their working processes.

[0022] Referring to the accompanying drawings, a coal bunker unblocking device for easy maintenance in this embodiment includes a bunker body 1, a discharge hopper 10, a mounting plate 11, a drive motor 12, and a rotating blade 16. The device is characterized in that: the discharge hopper 10 is detachably connected to the bottom discharge port of the bunker body 1 via a mounting assembly 2; a motor port is provided on the front side wall of the discharge hopper 10, and a mounting plate 11 is detachably mounted at the motor port; the mounting plate 11 is fixedly mounted on the front outer wall of the drive motor 12; the end of the output shaft of the drive motor 12 is connected to a rotating shaft 15, which extends into the discharge hopper 10; and a rotating blade 16 is mounted on the rotating shaft 15.

[0023] The installation assembly 2 includes an installation frame A4 and an installation frame B8. The installation frame A4 is installed on the outer wall of the bottom outlet of the bin 1, and the installation frame B8 is installed on the top outer wall of the discharge hopper 10. The installation frame A4 and the installation frame B8 have the same shape and size. The installation frame A4 and the installation frame B8 are provided with multiple sets of threaded through holes A9. The installation frame A4 and the installation frame B8 are fixed together by bolts 5 and threaded through holes A9, thereby fixing the discharge hopper 10 to the bottom of the bin 1.

[0024] The bottom surface of the mounting frame A4 is provided with multiple sets of connecting blocks 6 at intervals, and the top surface of the mounting frame B8 is provided with connecting slots 7 corresponding to the connecting blocks 6. When the mounting frame B8 is connected to the mounting frame A4, the connecting blocks 6 are inserted into the connecting slots 7 through a clearance fit. The insertion and positioning combination of the connecting blocks 6 and the connecting slots 7 ensures structural strength and avoids the risk of displacement during unblocking operations.

[0025] Both mounting frames A4 and B8 are rectangular frames.

[0026] The connecting plug 6 and the connecting slot 7 are evenly arranged in 4 sets.

[0027] The output shaft of the drive motor 12 is connected to the rotating shaft 15 via a coupling 14. The movable connection design between the coupling 14 and the rotating shaft 15 can buffer overload impacts and protect the drive motor from damage.

[0028] The lower part of the outer wall of the compartment 1 is provided with a support frame 3.

[0029] The mounting plate 11 is provided with multiple sets of threaded through holes B, and the front side wall of the discharge hopper 10 is provided with multiple sets of threaded blind holes corresponding to the threaded through holes B. The mounting plate 11 and the motor are fixed to the front side wall of the discharge hopper 10 by passing through the threaded through holes B of the mounting plate 11 and then screwing into the threaded blind holes.

[0030] The mounting plate 11 is provided with 4 sets of threaded through holes B, and the front side wall of the discharge hopper 10 is provided with 4 sets of threaded blind holes corresponding to the threaded through holes B.

[0031] The rotating blades 16 are provided in two sets, respectively located at the front and rear of the rotating shaft 15; each set of rotating blades 16 includes three long strip blades 17 arranged radially along the rotating shaft 15, and these three blades 17 are evenly spaced on the outer wall of the rotating shaft 15.

[0032] The working process of this embodiment is as follows: The silo body 1 is stably fixed by the support frame 3 to ensure the overall load-bearing capacity. The mounting frame A4 is fixed to the mounting frame B8 by the matching structure of bolts 5 and threaded through holes A9, realizing the modular connection of the main structure. The connecting plug 6 at the lower end of the mounting frame A4 is inserted into the connecting slot 7 at the upper end of the mounting frame B8 with a clearance fit. Four sets of plug-in structures are distributed around the mounting frame B8 to provide precise alignment and anti-torsional support. The drive motor 12 is fixed on the detachable mounting plate 11. The mounting plate 11 is installed on the front side wall of the discharge hopper 10 by fixing bolts 13 and threaded blind holes to achieve quick locking. The output shaft end of the drive motor 12 is linked with the rotating shaft 15 through the coupling 14 to form a rigid transmission, allowing a certain angular deviation to avoid motor overload damage. The rotating shaft 15 drives the rotating blade 16 to rotate in the discharge hopper 10, directly breaking up the arched coal blocks and promoting material flow.

[0033] When the drive motor 12 is powered on, it drives the rotating shaft 15 to rotate through the coupling 14, which in turn drives the rotating blade 16 to rotate. The rotating blade 16 shears and pushes the blocked coal seam. At the same time, the connecting block 6 and the connecting slot 7 bear the reaction force to ensure the stability of the overall structure. The crushed coal is discharged through the discharge hopper 10. The rotation speed of the rotating blade 16 can be adjusted according to the degree of blockage.

[0034] When disassembling, cleaning, or troubleshooting, the drive motor 12, coupling 14, shaft 15, and rotating blade 16 can be exposed by loosening or tightening the fixing bolts 13 on the threaded blind hole to remove the mounting plate 11. The components can be replaced individually without disassembling the entire hopper 1, reducing maintenance costs. At the same time, the open side plate design of the mounting plate 11 also makes it easy to clean the residual coal powder in the discharge hopper 10.

[0035] In addition, when disassembling, cleaning or troubleshooting, the bolt 5 can be unscrewed from the threaded through hole A9 through the quick-release structure on the mounting component 2 to separate the mounting frame A4 and the mounting frame B8, and then the mounting frame B8 and the discharge hopper 10 can be removed from the bin body 1. The components can be processed separately without disassembling the bin body 1 as a whole.
