Description
Technical field
The utility model relates to the industrial running protection technology of plant equipment, particularly a kind of wet milk water cut-off protection device that is not subjected to water quality impact.
Background technology
Wet milk is a kind of equipment that carbide alloy mixture is produced that is used for, the compound slip contains a large amount of alcohol, in the wet-milling process, can produce heat,, can cause the interior temperature of grinding machine sharply to raise in case of cutting off the water supply suddenly, cause detonation, even danger on fire, therefore, requirement must externally continuously be cooled off wet milk with cooling water.In the present production; general wet milk adopts the flow switch that is installed on the supply channel to carry out water cut-off protection; the operation principle of this flow switch is: utilize the pressure of water in the water pipe to promote a mechanical device; this mechanical device drives the microswitch action again, switches on or off the control circuit of wet milk motor.Be subjected to the influence of water quality, often cause mechanical device to be failure to actuate, after cutting off the water supply suddenly, can not in time cut off the wet milk power supply, exist very big potential safety hazard because of fouling is stuck.
The utility model content
The purpose of this utility model is in order to overcome above-mentioned employing flow switch wet milk to be carried out the deficiency that water cut-off protection exists; provide a kind of security higher; and reliable wet milk water cut-off protection device is active in one's movements; whether it can cut off the water supply to wet milk is detected automatically; in case the situation of cutting off the water supply occurs, it will make wet milk shut down fast automaticly.
This wet milk water cut-off protection device of the present utility model; comprise in the water inlet pipe that stretches into wet milk respectively; and be fixedly mounted on the conductivity detection probe on the water inlet pipe tube wall; be connected with the detection signal output line of two detector probe; the control device of conducting or cut-out wet milk control circuit; 12V dc source to the control device power supply; be connected the warning device on the control device; arbitrary detection signal output line in the described detector probe is connected on the negative pole of 12V dc source, and a relay contact in the described control device is connected on the control circuit of wet milk.
The utility model is simple and compact for structure, operates steadily, and cost of manufacture is low, can guarantee the safety of wet milk operation.The utility model is not subjected to the influence of water quality incrustation scale, moves safe and reliablely, except can be used for the wet milk water cut-off protection, can be used for the liquid level control of sintering furnace water cut-off protection and various non-combustible conducting liquids yet.
Description of drawings

Fig. 2 is a workflow block diagram of the present utility model;
Fig. 3 is the control circuit figure of the utility model embodiment control device.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As shown in Figure 1; this wet milk water cut-off protection device of the present utility model; comprise detector probe 4 and 5, control device 6,12V dc source 7 and warning device 8; wherein detector probe 4 and 5 is that conductive material (such as stainless steel, copper, materials such as alloy) is made; they stretch into respectively in the water inlet pipe 3 of wet milk 1; be fixedly mounted on the tube wall of water inlet pipe 3, but with water inlet pipe 3 insulation, keep certain distance between two detector probe 4 and 5.The detection signal output line of two detector probe all is connected with control device 6, and wherein detection signal output line directly is connected with the negative pole of the 12V dc source 7 of giving control device 6 power supplies, and another is connected on the interior integrated circuit of control device 6.The coil of contactor is connected on the contact that a relay arranged in the control device and wet milk 1 control circuit, implements the conducting or the cut-out of wet milk 1 control circuit.When there being current out-of-date (after cooling water flows into the wet milk cooling jackets from water inlet pipe 3 between detector probe 4 and 5, flow out from outlet pipe 2), " circuit " between two probes is conducting, the contactor conducting on the control device 6 control wet milk master circuit for controlling motor, and wet milk runs well.Between detector probe 4 and 5, there are not current out-of-date; when just the water inlet pipe 3 of wet milk 1 was cut off the water supply, " circuit " between two probes was cut off, and control device 6 moves immediately; cut off the contactor on the wet milk master circuit for controlling motor, wet milk master motor is also hard stop thereupon.Warning device 8 is connected on the control device 6, and when cutting off the water supply, control device 6 is connected the circuit of warning device 8 simultaneously, sends sound (light) alarm signal.
The control circuit that control device 6 adopts among the utility model embodiment as shown in Figure 3, this control circuit adopts NE555 time-base integrated circuit (IC) as the core original paper, 8. the pin of NE555 time-base integrated circuit, 4. pin and 1. pin connect the positive pole and the negative pole of 12V dc source 7 respectively, detector probe 4 and 5 output line are connected on A and the B, promptly a bars output line is connected to the negative pole of 12V dc source 7, and another bars output line is connected to the 2. pin of NE555 time-base integrated circuit.Between detection probe 4 and 5, there are current out-of-date, the 2. pin current potential of IC is " low ", 3. pin is exported " height " level, relay J 1 conducting, its normally opened contact adhesive, thus make relay J 2 conductings, its normally opened contact adhesive, and the normally opened contact of J2 is and connect for the coil of the contactor C (not drawing among the figure) on wet milk master motor (Rolling motor) control circuit, and therefore, the wet-milling function obtains powering and runs well.Otherwise; do not have current out-of-date between detector probe 4 and 5, the 2. pin current potential of IC is " height ", 3. pin output " low " level; relay J 1 outage; relay J 2 is outage at once also, and the normally opened contact of J2 disconnects, and wet milk master motor (Rolling motor) is shut down thereupon at once; thereby reach the purpose of water cut-off protection; simultaneously, warning device F is switched on, and sends sound (light) alarm signal.
The utility model can be used for the sintering furnace water cut-off protection equally, when detector probe 4 of the present utility model and 5 is installed on the upper and lower differing heights of fluid reservoir (case), can also be used for the liquid level control of various non-combustible conducting liquids.
