Description
Technical field
The utility model is mainly concerned with packaging facilities fields such as medicine, food, refers in particular to a kind of temperature control equipment that is applicable to cooling section in the tunnel sterilizing drier.
Background technology
At present, in the cooling section laminar flow casing of tunnel sterilizing and drying machine, generally adopt surface cooler, and surface cooler feed cooling medium and come work in cooling line as the cooling device that the cooling section laminar winds is cooled off.In the prior art, all adopt manually operated mode for the piping flow of surface cooler, promptly the operator is through observation or detect the height of laminar flow wind-warm syndrome degree, make judgement after, manually control the flow size in the cooling line.But; This manual mode of operation, the problem of existence just is: can't control in real time for the chilled-water flow size, problems such as human error, misoperation often occur; This just causes in the cooling section laminar flow casing laminar flow wind-warm syndrome to spend low or too high; And then can't control cavity temperature, being prone to produce condensed water, the material explosion causes sterilizing.
The utility model content
The technical problem that the utility model will solve just is: to the technical problem that prior art exists, the utility model provides a kind of simple and compact for structure, with low cost, laminar winds temperature control equipment that is used for cooling section that can carry out real-time regulated and then constant cavity temperature to the flow of chilled water in the surface cooler pipeline.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of laminar winds temperature control equipment that is used for cooling section; Comprise temperature controller, be installed on the temperature sensor in the cooling section laminar flow casing and be installed on the flow control valve on the surface cooler circulation line that said temperature controller is with the temperature of temperature sensor collection and the aperture of the relatively back controlled quentity controlled variable control valve of preset target temperature.
Further improvement as the utility model:
Said temperature sensor is more than one and is distributed in the cooling section laminar flow casing.
Said temperature sensor is one and is arranged in high efficiency particulate air filter in the cooling section laminar flow casing and transmits the workspace between the guipure.
Said flow control valve is the pneumatic proportional control valve, and said temperature controller links to each other with the pneumatic proportional control valve through a source of the gas.
Said flow control valve is installed on the outlet pipe in the circulation line.
Compared with prior art, the advantage of the utility model is: the utility model is used for the laminar winds temperature control equipment of cooling section, through in cooling section laminar flow casing, temperature sensor being set; Monitor the temperature of laminar winds in real time; And the aperture of regulating flow control valve according to real time temperature through temperature controller, and then the flow of chilled water in the control table cooler, thereby guaranteed the heat exchange effect of laminar winds at surface cooler; Can constant cavity temperature, be difficult for producing condensed water.

The specific embodiment
Below will combine Figure of description and specific embodiment that the utility model is explained further details.
As shown in Figures 2 and 3, the utility model is mainly used in the tunnel sterilizing and drying machine cooling section laminar flow casing 1, and cooling section laminar flow casing 1 is positioned at a side of high temperature casing 8.This cooling section laminar flow casing 1 comprises laminar flow blower fan 2, fan housing 3, high efficiency particulate air filter 4 and surface cooler 7 etc., transmits guipure 6 and penetrates from high temperature casing 8 one sides, passes from opposite side, sends into the material that needs dry sterilization 5 continuously and sees cooling section laminar flow casing 1 off.Cooling section laminar flow casing 1 inner air moves in a looping fashion; Suck air by laminar flow blower fan 2; Blow to high efficiency particulate air filter 4; Adopt fan housing 3 to connect between high efficiency particulate air filter 4 and the laminar flow blower fan 2, air filters after-blow to transmitting guipure 6 through high efficiency particulate air filter 4, to after transmitting material 5 on the guipure 6 and carrying out after the cold and hot exchange sending return air channel 11 to through circulating fan 10; The surface cooler 7 that continues to flow through, air after the heat exchange fin heat exchange on the surface cooler 7 once more tegillum flow fan 2 suck and form the circulated airs cooling.In this process, surface cooler 7 is as heat exchange element, and the height of its heat exchange efficiency has just directly determined the temperature of cooling section laminar flow casing 1 inner laminar flow wind.
As shown in Figure 1; The utility model is used for the laminar winds temperature control equipment of cooling section; Comprise temperature controller 14, be installed on the temperature sensor 9 in the cooling section laminar flow casing 1 and be installed on the flow control valve 16 on surface cooler 7 circulation lines, circulation line comprises water inlet pipe 13, outlet pipe 17 and water source; Wherein, temperature sensor 9 can adopt temp probe, is used for detecting in real time the laminar winds temperature in the cooling section laminar flow casing 1 and should detects data sending to temperature controller 14, is set with target temperature in the temperature controller 14.When detected temperature is lower than design temperature; Temperature controller 14 just sends control instruction to flow control valve 16; The aperture of flow control valve 16 is reduced; This moment, cooling water 12 entering surface coolers 7 flows will reduce, and the heat exchange efficiency of cooling section laminar flow casing 1 inner laminar flow wind and surface cooler 7 will reduce.When detected temperature is higher than design temperature; Temperature controller 14 just sends control instruction to flow control valve 16; The aperture of flow control valve 16 is become big; This moment, cooling water 12 entering surface coolers 7 flows will subtract greatly, and the heat exchange efficiency of cooling section laminar flow casing 1 inner laminar flow wind and surface cooler 7 will improve.By the way, just can regulate the temperature of laminar winds in the cooling section laminar flow casing 1 in real time, accurately, reliably, to guarantee the service behaviour of whole cooling section.
In the present embodiment, temperature sensor 9 is a plurality of, is distributed in the cooling section laminar flow casing 1, and temperature controller 14 can be got its average as judgment value.Temperature sensor 9 also can be limited one, mainly is arranged in through high efficiency particulate air filter 4 and filters after-blow to the workspace temperature that transmits guipure 6 places.
In the present embodiment; Flow control valve 16 can adopt the pneumatic proportional control valve; Temperature controller 14 can link to each other with ratio adjusting valve through a source of the gas 15, and the control instruction that temperature controller 14 sends is directly delivered to source of the gas 15, drives the adjusting of flow control valve 16 through source of the gas 15.Certainly, in other embodiments, also can directly adopt elements such as electric ratio adjusting valve or hydraulic proportional control valve.
Because the mode that goes out on advancing under being that the circulation line of general surface cooler 7 adopts is in saturation state all the time to guarantee the cooling medium in surface cooler 7 cavitys, does not produce cavity, so in the present embodiment, flow control valve 16 is installed on the outlet pipe 17.
Below only be the preferred implementation of the utility model, the protection domain of the utility model also not only is confined to the foregoing description, and all technical schemes that belongs under the utility model thinking all belong to the protection domain of the utility model.Should be pointed out that for those skilled in the art,, should be regarded as the protection domain of the utility model in the some improvement and the retouching that do not break away under the utility model principle prerequisite.
