The utility model relates to a heating apparatus for a breather, comprising a temperature-control circuit, a heating wire, and a silica gel plate, wherein the temperature-control circuit is connected with a heating wire; the heating wire is embedded in the silica gel plate; and the silica gel plate is sleeved upon the breather. Compared with the prior art, the heating apparatus of the utility model features wide application scope, safety, reliability, and convenient overhaul, and can ensure the smooth breathing of the breather.
Description
Technical field
The utility model relates to a kind of heater, especially relates to a kind of respirator and uses heater.
Background technology
At present in the pharmaceutical industry; The respirator configuration of the aseptic exhaust outlet of water for injection storage tank and accessory jar has problems: the steam that hot water produces in jar is run into the extremely strong PTFE film surface meeting condensation of cold hydrophobicity; And influence exhaust effect, serious causes a jar flat and broken phenomenon because of unsmooth breath when the startup pump draws water.And the prior art situation is: 1. the respirator filter core is used polypropylene screen, and because of the hole very much not can influence exhaust, but bacteria-eliminating efficacy is not good, and the microbiological contamination possibility is arranged.2. though the respirator filter core removes mycoderm with PTFE, adds a bypass, steam is directly discharged from by-pass port in jar, and the microbiological contamination possibility is more arranged.
The utility model content
The purpose of the utility model is exactly to provide in order to overcome the defective that above-mentioned prior art exists that a kind of scope of application is wide, safe and reliable, maintenance is convenient, and the device that can ensure respiration is breathed unobstructed respirator and used heater.
The purpose of the utility model can realize through following technical scheme: a kind of respirator is used heater; It is characterized in that; This heater comprises temperature-control circuit, heating wire and silica gel plate; Described temperature-control circuit is connected with heating wire, and described heating wire is embedded in the silica gel plate, and silica gel plate is enclosed within on the respirator.
Described temperature-control circuit comprises supply socket switch, first fuse, earth leakage circuit-breaker, power supply indicator, heater switch, intelligent temperature controller, solid-state relay, burner on light and second fuse; One termination power of described supply socket switch is anodal, and the other end is through an input of first fuse connection earth leakage circuit-breaker, and another of earth leakage circuit-breaker imported termination power cathode; An output of described earth leakage circuit-breaker is through an input of heater switch connection of intelligent temperature controller, another input of another output connection of intelligent temperature controller of earth leakage circuit-breaker; An output of described intelligent temperature controller connects an end of second fuse through solid-state relay, and the other end of second fuse connects an end of heating wire, and another output of intelligent temperature controller connects the other end of heating wire; Two inputs of described power supply indicator also are connected in two outputs of earth leakage circuit-breaker; One end of described burner on light is connected between the solid-state relay and second fuse, and the other end of burner on light is connected between heating wire and the intelligent controller.
Described temperature-control circuit control heating-up temperature is between 20 ℃～150 ℃.
The periphery of described silica gel plate also is with the silica gel muff.
Compared with prior art, the utlity model has following advantage:
One, the scope of application is wide: the respirator heating of the aseptic exhaust outlet of water for injection storage tank and material-compound tank to prevent in aseptic exhaust respirator, forming condensed water, influences exhaust effect;
Two, safe and reliable: the utility model is the accurate temperature controller independently, and heater and heat-insulation system can be realized user's self-control and replacement temperature set points through automatic control;
Three, ensure respiration unobstructed: start the pump Shi Buhui that draws water and cause a jar flat and broken phenomenon because of unsmooth breath.Bacteria-eliminating efficacy is good;
Four, maintenance is convenient: Aviation Connector, fusing fuse, earth leakage circuit-breaker are adopted in the utility model wiring, are convenient to maintenance.
Description of drawings
Fig. 1 is the circuit diagram of the utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
Embodiment
As shown in Figure 1, a kind of respirator is used heater, and this heater comprises temperature-control circuit, heating wire 9 and silica gel plate, and temperature-control circuit is connected with heating wire, and heating wire is embedded in the silica gel plate, and the silica gel plate that is embedded with heating wire is enclosed within on the respirator.Temperature-control circuit comprises supply socket switch 1, first fuse 2, earth leakage circuit-breaker 3, power supply indicator 4, heater switch 5, intelligent temperature controller 6, solid-state relay 7, burner on light 10 and second fuse 8; One termination power of supply socket switch 1 anodal (220V alternating current fire wire), the other end is through an input of first fuse, 2 connection earth leakage circuit-breakers 3, and another of earth leakage circuit-breaker 3 imported termination power cathode (220V alternating current zero line); An output of earth leakage circuit-breaker 3 is through an input of heater switch 5 connection of intelligent temperature controllers 6, another input of another output connection of intelligent temperature controller 6 of earth leakage circuit-breaker 3; An output of intelligent temperature controller 6 is through an end of solid-state relay 7 connections second fuse 8, and the other end of second fuse 8 connects an end of heating wire 9, and another output of intelligent temperature controller 6 connects the other end of heating wire 9; Two inputs of power supply indicator 4 also are connected in two outputs of earth leakage circuit-breaker 3; One end of burner on light 10 is connected between the solid-state relay 7 and second fuse 8, and the other end of burner on light 10 is connected between heating wire 9 and the intelligent controller 6.Temperature-control circuit control heating-up temperature is between 20 ℃～150 ℃.The periphery of silica gel plate also is with the silica gel muff.
Heater can guarantee that the temperature in the respirator shell is higher than the temperature in the storage tank, makes the film surface not produce condensed water, and it is unobstructed to ensure respiration.Owing in temperature control, adopt intelligent temperature controller to trigger solid-state relay, solve noise problem.On circuit, adopt two cover safeties: the heating plate sub-loop cover fuse (second fuse) that opens circuit, power supply one cover fuse (first fuse).Two groups of easy to operate Aviation Connector are adopted in wire terminal: one group of output line, one group of heating plate sub-loop.Control cabinet adopts press forming of aluminium alloy, and is attractive in appearance and generous.
