Description
Technical Field
The utility model relates to a thermal power equipment especially relates to a vacuum belt hydroextractor blanking mouth putty is reported to police and emergency stop device.
Background
At present, a vacuum belt conveyor is generally adopted in a thermal power plant to dehydrate gypsum, and the gypsum is recycled to a gypsum warehouse in a short time. And the gypsum falls into the in-process in gypsum storehouse on the vacuum belt hydroextractor belt, flows through the blanking mouth, exists the putty and leads to the accumulational risk of gypsum, finally leads to the gypsum to block up the blanking mouth, and unrestrained ground is difficult to the clearance, blocks up vacuum belt hydroextractor rotating part even, causes the equipment damage. Therefore, the flowing state of the gypsum must be monitored to prevent the spread of accidents.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that, overcome the above-mentioned defect that prior art exists, provide a real-time supervision blanking mouth material state, prevent that the material from taking place accumulational vacuum belt hydroextractor blanking mouth putty and reporting to the police and emergency stop device.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a vacuum belt hydroextractor blanking mouth putty is reported to police and emergency stop device, is including setting up the inspection hole on vacuum belt hydroextractor end baffle, inspection hole department is equipped with putty detection switch element who is used for controlling dewatering machine driving system, putty detection switch element is connected with control system.
Further, the number of the inspection ports is 2.
Furthermore, the top of the blocking material detection switch element is provided with an anti-collision protection plate which is positioned on the inner side of the end baffle of the vacuum belt dehydrator. The material collision is prevented from generating false alarm, and the erosion of the blocking material detection switch element caused by medium flow is reduced.
Further, the height of the top of the putty knife element from the ground is 2/5 the height of the end stop, and the distance from the putty knife element to the side of the end stop is 1/3 the width of the end stop. The installation of putty switch element is convenient.
Further, the blanking mouth and the bottom warehouse of vacuum belt hydroextractor are connected, blanking mouth upper portion is equipped with the dust screen, be equipped with the slagging-off hole on the dust screen. The medium transferred by the vacuum belt dehydrator flows through the end baffle plate to the blanking port from top to bottom at the end part of the medium, and finally falls into the bottom warehouse.
The utility model can effectively prevent the material blocking accident caused by the lack of supervision; when slight material blockage occurs, remote alarm is provided to arouse the alertness of personnel, and measures are taken in time to eliminate the hidden danger of serious material blockage; if serious material blockage occurs, the emergency stop is automatically realized.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-3, the present embodiment includes two inspection ports disposed on the end baffle 2 of the vacuum belt dehydrator 1, and the first inspection port 3 and the second inspection port 4 are disposed with plugging detection switch elements, i.e., a first plugging detection switch element 5 and a second plugging detection switch element 6, for controlling the power system of the dehydrator, wherein the plugging detection switch elements and the inspection ports are located on the same horizontal plane, and the plugging detection switch elements are connected to the control system. And an anti-collision protective plate 7 is arranged at the top of the blocking detection switch element, and the anti-collision protective plate 7 is positioned on the inner side of the end baffle 2 of the vacuum belt dehydrator 1. The blanking port 8 of the vacuum belt dehydrator 1 is connected with the bottom warehouse 9, the upper part of the blanking port 8 is provided with a dust screen 10, and the dust screen 10 is provided with two deslagging holes 11.
In this embodiment, the height of the top of the plugging detection switch element from the ground is 2/5 the height of the end fence 2, and the distance from the plugging detection switch element to the side of the end fence 2 is 1/3 the width of the end fence 2.
When the device works, materials fall into a bottom warehouse 9 through a blanking port 8 by a belt; when the blanking port 8 is partially blocked, the first blocking detection switch element 5 or the second blocking detection switch element 6 acts, an action signal lasts for 2 seconds and sends out an alarm signal, if the duration is less than 2 seconds, the alarm is not given, the design can effectively avoid false alarm caused by mistakenly touching the blocking detection switch element by the flowing material, and when the local blockage occurs, the blanking port 8 can be dredged through the slag removing hole 11 on the dust screen 10; when whole blanking mouth 8 all blocks up, two putty detection switch components move simultaneously, reach 5 seconds after when the time of the two simultaneous actions, trigger emergency shutdown protection logic, disconnection vacuum belt hydroextractor 1's power motor 12 realizes emergency shutdown, when blanking mouth 8 appears all blockking up, under the outage circumstances, staff's accessible inspection hole gets into bottom warehouse 9 and dredges the transportation to accumulational material.
Various modifications and variations of the present invention may be made by those skilled in the art, and they are within the scope of the present invention provided they are within the scope of the claims and their equivalents.
What is not described in detail in the specification is prior art that is well known to those skilled in the art.
