Example 2:
example 1 is the same as in example 1 except for the following control principle:
as shown in fig. 6: the controller 29 is controlled by a dual relay circuit. The control principle of the controller 29 is as follows: will 2 relays J 1 And J 2 Equivalent switch K respectively with low-position control reed 35 1 Equivalent switch K of high-order control reed 34 2 And (5) connection. The power supply circuit of the electromagnetic valve 40 and the relay J 1 Is a normally open contact C of (2) 1 Relay J 2 Normally closed contact C of (2) 2 Serial connection; simultaneous relay J 1 Adopts parallel power supply, and the parallel power supply circuit and the relay J of the other path of the power supply 1 Is a normally open contact C of (2) 1 Relay J 2 Normally closed contact C of (2) 2 The floating ball 33 is connected in series, thereby ensuring that when the floating ball 33 falls to the lowest position to the low position limiting ring 32, the floating ball 33 attracts the low position control reed 35 to close with the second contact, so that the equivalent switch K of the low position control reed 35 1 Closing, relay J 1 Electrifying and normally open contact C thereof 1 Closing. And then relay J 2 Normally closed contact C when not energized 2 The closed state is maintained, so that the electromagnetic valve 40 is electrified, and the disinfection tank 1 is replenished with disinfection solution through the high-level liquid storage tank 2. Along with the rising of the liquid level in the disinfection tank 1, according to the principle of a communicating vessel, the floating ball 33 floats upwards to drive the annular magnet 41 inside the floating ball to rise so as to leave the low-level control reed 35, and the low-level control reed 35 is disconnected with the second contact to lead the equivalent switch K of the low-level control reed 35 to be realized 1 Breaking the relay J 1 One power supply is lost, but because one parallel circuit is in the electrified state before, the relay J 1 The state of energization is kept continuously, thereby ensuring that the electromagnetic valve 40 is energized continuously, the liquid level in the disinfection tank 1 is increased continuously, and the water level meter is provided withThe movable floating ball 33 floats upwards, when the floating ball 33 floats upwards to the high-position limiting ring 31, the floating ball 33 attracts the high-position control reed 34 to be closed with the first contact, and the equivalent switch K of the high-position control reed 34 2 Closing the relay J 2 Electrifying and relay J 2 Normally closed contact C of (2) 2 Open to thereby make the relay J 1 And the electromagnetic valve 40 is simultaneously de-energized, and the high-level liquid storage tank 2 stops supplementing disinfectant into the disinfection tank 1. With the continuous volatilization of the sterilizing liquid and the taking away of a part of the sterilizing liquid by the shoes worn by the personnel entering the sterilizing tank 1, the liquid level in the sterilizing tank 1 is lowered again, the floating ball 33 is lowered accordingly, when the floating ball 33 returns to the vicinity of the low limit ring 32 again, the low control reed 35 is closed with the second contact, the electromagnetic valve 40 is electrified again, and the liquid level in the sterilizing tank 1 is raised again, and the above process is repeated. If the device is powered off and cannot automatically supplement the sterilizing liquid, the manual valve 16 can be used for supplementing the sterilizing liquid into the sterilizing tank 1 by manually observing the height of the glass liquid level meter 18.
When the disinfection tank is specifically manufactured, the tank cover plate 5, the peripheral side plates 7, the tank bottom plate 6 of the top plate 9, the floating plate 19, the closed body 23, the high-level liquid storage tank 2 and various auxiliary pipelines of the disinfection tank 1 are manufactured according to the conventional technology, and the electromagnetic valve 40, the manual valve 16, the connecting lead, the spring 24, the first spring hook 27 and the second spring hook 28 with certain specifications are purchased. After the above-mentioned work is prepared, the closing body 23, the spring 24, the first spring hook 27 and the second spring hook 28 are connected and installed in the manner shown in fig. 4; placing the floating plate 19 into the disinfection tank 1, adjusting the position of the floating plate 19 to enable the center of the floating plate 19 to coincide with the center of the tank bottom plate 6, enabling all sides of the guardrail plate 20 of the floating plate 19 to be parallel to all sides of the surrounding side plates 7, covering the processed tank cover plate 5 on the surrounding side plates 7 and the guardrail plate 20, and paying attention to the fact that the inner surrounding side plates 8 of the tank cover plate 5 are tightly attached to the guardrail plates 20 of the floating plate 19, and paying attention to the fact that the inner surrounding side plates 8 are required to be sleeved on the guardrail plates 20, so that the floating plate 19 cannot horizontally move. After the above-mentioned work is completed, the liquid level switch component, controller 29, high-level liquid storage tank 2, glass liquid level meter 18 and auxiliary pipeline are connected with all the connecting holes led out from disinfection tank 1 by means of conventional technology, at the same time the sediment discharge hole 42 is plugged by means of conventional plug, and when it is necessary to discharge sediment, the plug can be opened. After the disinfection tank 1 is installed, the disinfection solution can be injected into the disinfection tank 1, along with the injection of the disinfection solution, the floating plate 19 begins to float upwards, and the highest liquid level of the injected disinfection solution is controlled so that when no personnel enter the disinfection tank, the sealing body 23 leaves the liquid guide hole 22 on the bottom plate 21 of the floating plate 19, thereby losing the sealing state of close contact. The height position of the floating ball 33 (stainless steel hollow floating ball) is adjusted, so that the height of the high and low limiting rings meets the actual requirements; the device is electrified, the high-level liquid storage tank 2 is filled with disinfectant, and the device can start to work.
