Advantageous Effects of the present invention is:
The internal condensation water of cold storage proofing box and other refrigerating equipments can be evaporated by apparatus of the present invention, ground in bakery can be kept dry, clean without the need to facility drainings such as floor drains.The present invention designs in conjunction with the actual use needs of client, and structure is simple, and successful, has wide market prospects.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
As shown in Figure 1 and Figure 2, the composition of apparatus of the present invention comprises: stainless steel trough 1, electric heating tube 2, float switch 3, A.C. contactor 4, mechanical temperature controller 5 and temperature controller sensing rod for temperature 6.Electric heating tube 2 and float switch 3 are installed in stainless steel trough 1, and are electrically connected by the A.C. contactor 4 of wire with stainless steel trough 1 outside; Thermostat sensing rod for temperature 6 is fixed on electric heating tube 2, and is electrically connected by the mechanical temperature control type device 5 of wire with stainless steel trough 1 outside, and mechanical temperature control type device 5 is electrically connected with electric heating tube 2 again.In addition, optionally arrange the cover plate 7 having condensed water water inlet 8 at stainless steel trough 1 top, this condensed water water inlet 8 should be in correspondence position with the condensed water discharge outlet of cold storage proofing box.
Float switch 3 is that a kind of structure is simple, Liquid level device easy to use, and it uses magnetic force running, and mechanical connector, operates simple and reliable.When float switch 3 measured medium buoyant float, float drives main body to move, and the magnet of the float other end is by the magnet switch motion on control lever simultaneously.Float switch 3 does not need to provide power supply, does not have complicated circuit, has the advantages such as, long working life less than common mechanical volume of switch.
A.C. contactor 4 forms primarily of four parts: electromagnetic system, comprises sucking coil, dynamic iron core and static iron core; Contact system, comprises three groups of main contacts and one to two group is often opened, normally closed auxiliary contact, links mutually together with dynamic iron core; Arc-control device, so that rapid breaking arc, avoids burning out main contact; Insulation crust and annex, comprise various spring, transmission mechanism, short-circuited conducting sleeve, binding post etc.When the coil is energized, static iron core produces electromagnetic attraction, will move iron core adhesive, and because contact system and dynamic iron core link, therefore dynamic iron core drives three movable contact springs to run simultaneously, the closing of contact, thus switches on power.When the coil is de-energized, suction disappears, and dynamic iron core interlock part relies on the reaction force of spring and is separated, and main contact is disconnected, cuts off the electricity supply.
Mechanical temperature controller 5 is divided into pressure type, double-metal sheet type, capillary type.Conventional double-metal sheet type is according to object rising-heat contracting-cold principle design.Rising-heat contracting-cold is the general character of object, and the degree of its rising-heat contracting-cold of different objects is different.The two sides of bimetal leaf is the conductor of different material, makes two gold plaque bend under varying temperatures, encounter contact or the switch of setting, the circuit of setting is started working because expansion-contraction degree is different.
The course of work of the present invention and principle as follows:
Be linked into same power supply by parallel with cold storage proofing box for apparatus of the present invention, apparatus of the present invention be arranged on the rational position of proofing box simultaneously, so that condensed water flows into.At cold storage proofing box from when refrigerating patten transformation for proofing pattern, producing a large amount of condensed waters, being flow in stainless steel trough 1 by the condensed water water inlet 8 on cover plate 7.
When the condensate water level in stainless steel trough 1 is raised to certain altitude position time, float switch 3 is connected, and after float switch 3 is connected, the A.C. contactor 4 controlling electric heating tube 2 closes, and electric heating tube 2 starts heating, evaporates the condensed water in stainless steel trough 1; When the water level of condensed water drops to certain altitude position, float switch 3 disconnects, and the A.C. contactor 4 of control electric heating tube 2 is disconnected, and electric heating tube 2 stops heating.
Mechanical temperature controller 5 shields in the course of the work, is constantly measured the surface temperature of electric heating tube 2 by temperature controller sensing rod for temperature 6.If electric heating tube 2 is in heating process, float switch 3 can not normally disconnect, water in stainless steel trough 1 will evaporate to dryness, electric heating tube 2 will be in dry-fire condition, when the surface temperature of electric heating tube 2 is elevated to certain value, the temperature recorded is delivered to mechanical temperature controller 5 by temperature controller sensing rod for temperature 6, and mechanical temperature controller 5 controls electric heating tube 2 and stops heating.
Above-described is only the preferred embodiment of the present invention, the invention is not restricted to above embodiment.Be appreciated that the oher improvements and changes that those skilled in the art directly derive without departing from the spirit and concept in the present invention or associate, all should think and be included within protection scope of the present invention.
