Abstract
Novel coal flows detection device. The coal flow detection technology is widely applied to various large-fire systems, and a traditional contact type coal flow switch is difficult to maintain in a later period due to the fact that the switch is jammed and cannot automatically rebound as the service time is increased and the coal conveying working environment is severe, and the contact type abrasion is large. The utility model discloses a constitution includes: belt weigher measurement system, belt weigher measurement system include belt weigher (3) and belt (1), the belt lower part install belt weigher, coal flow switch (2) are installed on upper portion, belt weigher and belt weigher control box (4) connect, belt weigher measurement system model be ICS-300, belt weigher control box in take 4 ~ 20mA current signal of weighing all the way and turn into 0 ~ 2000T's coal flow instantaneous flow signal, belt weigher measurement system be 2 sets. The utility model is used for the coal flows and detects.
Description
Technical Field
The utility model relates to a coal flows and detects technical field, concretely relates to novel coal flows and detects device.
Background
The coal stream detection technology has been widely applied to each big fire system, and traditional contact coal stream switch, along with the live time increase with defeated coal operational environment is abominable, lead to the switch to take place the bite and can not kick-back automatically, and the great later maintenance difficulty of wearing and tearing of contact, and photoelectric type coal stream switch, because of belt rising degree and the personnel's mode change of going up coal, the rate of accuracy is lower, and dust influences personnel's regular sanitation and cleans, very easily causes the mistake and sends out. Disclosure of Invention
The utility model aims at providing a novel coal flows and detects device.
SUMMERY OF THE UTILITY MODEL
The above purpose is realized by the following technical scheme:
a novel coal flow detection device comprises: belt weigher measurement system, belt weigher measurement system include belt weigher and belt, the belt lower part install belt weigher, the coal current switch is installed on upper portion, belt weigher and belt weigher control box connect, belt weigher measurement system model be ICS-300, belt weigher control box in take 4 ~ 20mA current signal of weighing of the same kind and turn into 0 ~ 2000T's coal current instantaneous flow signal, belt weigher measurement system be 2 sets.
Has the advantages that:
the utility model relates to a novel coal flows detection device adopts two sets of belt weigher measurement systems, selects actual coal flow signal from a belt, presses down dirt as another belt dry fog and opens the instruction, and the restriction is judged on the increase, and output switching value judges whether have the coal on the belt, can furthest reduce the overspray phenomenon, does not receive working medium, the direct influence that brings of operational environment, effectively avoids the influence that environment and wearing and tearing caused equipment, purchasing cost is low, and the flow is simple, and the practicality is strong.
Description of the drawings:
FIG. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a top view of FIG. 1;
in the figure: 1. the device comprises a belt, 2, a coal flow switch, 3, a belt scale and 4, and a belt scale control box.
The specific implementation mode is as follows:
example 1:
a novel coal flow detection device comprises: the belt weigher metering system comprises a belt weigher 3 and a belt 1, the belt weigher is installed on the lower portion of the belt, a coal flow switch 2 is installed on the upper portion of the belt, the belt weigher is connected with a belt weigher control box 4, the belt weigher metering system is ICS-300 in type, one path of 4-20 mA weighing current signal is taken from the belt weigher control box and converted into a coal flow instantaneous flow signal of 0-2000T, and the number of the belt weigher metering systems is 2;
the working principle is as follows: two sets of belt weigher metering systems are arranged on one belt, the type is ICS-300, an actual coal flow signal is selected from one belt, a 4-20 mA weighing current signal is taken from an original belt weigher control box and converted into a coal flow instantaneous flow signal of 0-2000T, the coal flow instantaneous flow signal is used as a dry fog dust suppression start-stop instruction of the other belt, upper limit judgment is added, and switching value is output to judge whether coal exists on the belt.
Claims (1)
