Abstract
Description
Technical Field

[0002] In the coal preparation industry, chutes are installed between washing and processing equipment and storage and transportation devices, undertaking tasks such as conveying, sealing, connecting, and transferring. Coal preparation plants have numerous pieces of equipment, therefore chutes, as a type of non-standard equipment, constitute a large number in coal preparation plants. Due to the complexity and special nature of the coal transportation process, problems such as insensitive coal pile-up protection switches and imperfect protection performance may emerge during production operation. In actual production, if coal pile-up or blockage occurs in the chute, the chute space will become increasingly narrow, causing severe coal accumulation, ultimately leading to material spillage, equipment overload, tearing, and damage, seriously affecting the safe operation of the equipment. Commonly used coal pile-up protection devices include counterweight type (tilted type), electrode type, rotary paddle type, and pressure-sensitive type, etc., which have certain requirements for the operating environment. If the operating environment does not meet the requirements, the coal pile-up protection device will often malfunction, leading to shutdown and affecting production.

[0022] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0023] According to an embodiment of this utility model, a chute blockage treatment device is provided. Please refer to [link / reference]. Figures 1 to 3 The system includes: a chute 1; and a detection component 2, which is disposed in the chute 1. The detection component 2 has a signal triggering part and a signal transmitting part. The signal triggering part is movably disposed, and a preset distance is provided between the signal triggering part and the signal transmitting part. When the movable end of the signal triggering part exceeds the preset distance set with the signal transmitting part, and the duration exceeds a preset time, the signal transmitting part is triggered to send a signal to process the material.
[0024] By adopting the above technical solution, the combination of mechanical triggering of the signal triggering unit and delayed judgment of the signal transmitting unit effectively distinguishes between instantaneous material impact and continuous blockage, significantly reducing the probability of false triggering caused by brief material fluctuations and improving the accuracy and reliability of coal pile detection.
[0025] Preferably, the movable end of the signal triggering part exceeds the preset distance of 15cm from the signal transmitting part.
[0026] Please refer to Figure 3The detection component 2 includes: a mounting plate 3 having a movable space, the mounting plate 3 being mounted on the chute 1; a detection element 4, the detection element 4 being mounted on the mounting plate 3, with the detection end of the detection element 4 located above the movable space; a controller electrically connected to the detection element 4; a trigger plate 5, at least a portion of the trigger plate 5 being rotatably disposed within the movable space, with the trigger end of the trigger plate 5 located within the chute 1; and the movable end of the trigger plate 5 located above the movable space. When the material in the chute 1 applies force to the trigger end of the trigger plate 5, and the movable end of the trigger plate 5 moves away from the detection end of the detection element 4 for more than a preset time set by the controller, a signal transmitter emits a signal to provide a warning. The detection element 4 and the controller form a signal transmitter; the mounting plate 3 and the trigger plate 5 form a signal trigger.
[0027] Furthermore, the detection component 4 is a proximity switch or a distance sensor.
[0028] By adopting the above technical solution, the non-contact detection scheme between the trigger plate 5 and the detection element 4 avoids direct impact of materials on the proximity switch, significantly reducing mechanical wear; and by using the controller's preset time judgment logic, it effectively distinguishes between instantaneous material fluctuations and actual blockages, reducing false triggering rate and improving detection reliability.
[0029] Furthermore, the chute blockage treatment device also includes an alarm, which is electrically connected to the controller.
[0030] By adopting the above technical solution and through the real-time signal linkage between the alarm and the detection component 2, an audible and visual alarm is immediately issued when the trigger plate 5 deviates continuously, thereby achieving rapid early warning of coal pile accidents, buying time for manual intervention, and avoiding equipment overload damage.
[0031] Please refer to Figure 1 The chute blockage treatment device also includes a blockage treatment component 6, which is signal-connected to the detection component 2 so that the blockage treatment component 6 can be driven to treat the blockage material by the signal emitted by the detection component 2.
[0032] By adopting the above technical solution and through the automatic linkage between the detection component 2 and the blockage handling component 6, an integrated closed-loop control of "detection-handling" is achieved, which can actively clear blockages without manual intervention, greatly improving the efficiency of fault handling.
[0033] Please refer to Figure 2 and Figure 3The blockage treatment component 6 includes: a connecting plate 7, which is movably disposed within the chute 1; an agitating plate 8, which is mounted on one side of the connecting plate 7 and whose extension direction is perpendicular to that of the connecting plate 7; and a rotating plate 9, which is movably disposed on the side of the connecting plate 7 away from the agitating plate 8. The rotating plate 9 is connected to the connecting plate 7, and at least a portion of the rotating plate 9 is located on the outer wall of the chute 1, so as to drive the connecting plate 7 and the agitating plate 8 to move within the chute 1 through movement.
[0034] By adopting the above technical solution, the driving force is efficiently transmitted to the inside of the chute 1 through the exposed design of the rotating plate 9, which drives the connecting plate 7 and the stirring plate 8 to move, so as to stir the material accumulated in the chute 1 through the stirring plate 8, which facilitates the unblocking of the material.
[0035] Please refer to Figure 1 and Figure 2 The blockage treatment component 6 also includes a drive member 10, which is electrically connected to the signal transmitting unit. The drive member 10 is rotatably mounted on the chute 1, and the drive end of the drive member 10 is driven to be connected to the rotating plate 9 so as to drive the rotating plate 9 to move through the drive member 10.
[0036] By adopting the above technical solution, the direct connection between the drive component 10 and the rotating plate 9 avoids intermediate losses in the power transmission chain; the start and stop of the drive component 10 are directly controlled by electrical signals, ensuring the immediacy and synchronicity of the blockage handling action.
[0037] Please refer to Figure 1 and Figure 2 The chute 1 has an opening, and the connecting end of the rotating plate 9 passes through the opening and connects to the connecting plate 7. The blockage treatment component 6 also includes a flexible sealing plate 11, which is connected to the chute 1 and the rotating plate 9 respectively to close the opening.
[0038] By adopting the above technical solution and the dynamic sealing scheme of the flexible sealing plate 11, the gap of the moving opening is completely sealed while ensuring the free movement of the rotating plate 9, preventing coal powder leakage and pollution of the equipment, and isolating external dust from entering the chute.
[0039] Please refer to Figure 2 The stirring plate 8 is provided with a sharp part 12.
[0040] By adopting the above technical solution, the sharp part 12 is locally reinforced to concentrate stress and break up caking materials, significantly improving the penetration ability of high viscosity or compacted coal blocks, and avoiding excessive resistance from materials during the dredging process of the stirring plate 8, which would affect the stirring and dredging effect.
[0041] Furthermore, the sharp part 12 may be located at the top and / or bottom of the stirring plate 8.
[0042] Working principle:
[0043] When the material in chute 1 flows normally, the trigger end of trigger plate 5 is not subjected to abnormal pressure, and the movable end of trigger plate 5 maintains a preset distance from the detection end of detection element 4. Once material accumulates or blocks in chute 1, the accumulated material will push the trigger end of trigger plate 5, causing its movable end to move away from the detection end of detection element 4. If this deviation continues for more than the preset time of the controller, detection element 4 is triggered, and the controller determines that a blockage has occurred. The controller then drives the alarm to issue an alarm to remind the operator, and at the same time sends a drive signal to the blockage handling component 6. After receiving the signal, the drive component 10 starts, carrying... The rotating plate 9 moves; the movement of the rotating plate 9 is transmitted to the agitator 8 connected to it through the connecting plate 7, so that the agitator 8 and its sharp part 12 reciprocate in the blocked material to break and clear it; during this process, the flexible sealing plate 11 always moves with the rotating plate 9 and maintains a dynamic seal on the movable opening of the chute 1 to prevent material leakage; when the blockage is cleared and the material resumes flow, the trigger plate 5 returns to its original position under the action of gravity or the reset mechanism, the movable end of the trigger plate 5 re-enters the effective detection range of the detection element 4, the controller stops the alarm and shuts off the drive element 10, and the device resets and stands ready.
