Description

Low-temperature drying and refrigerating system

Technical Field

The utility model belongs to the technical field of food processing equipment, in particular to low temperature stoving refrigerating system.

Background

In the present food, especially aquatic product drying treatment process, low-temperature drying and high-temperature drying greatly improve the product quality, the general drying temperature of low-temperature drying is lower than the indoor temperature of a workshop, and the equipment is required to have a refrigerating function. The refrigeration system adopted for low-temperature drying has a special design, and two sets of condensing devices, namely a condenser I and a condenser II, are required. The high-temperature and high-pressure gas discharged by a compressor of the system enters two condensers indoors and outdoors through an oil-gas separator, a pipeline, a tee joint and an electromagnetic valve. The condensed Freon liquid is required to flow back to the liquid storage tank when entering the two condensing devices. Because the liquid storage tank has only one return valve, the two condensers need to return to the liquid storage tank through a tee joint when returning. Because two kinds of condensers are cross work, this kind of structure causes wherein in the condenser reflux liquid of work partly can shunt to in another non-operating condition condenser easily, because inside has another condenser to shunt the liquid that gets into when another condenser work, the system pressure increases to whole system protection shut down in the twinkling of an eye when the start-up work in the condenser, influences normal production. Frequent stops can affect production efficiency and product quality.

Disclosure of Invention

The invention aims to overcome the technical defects and provide a low-temperature drying refrigeration system which can effectively prevent condensate from entering another condenser when the condensate flows back.

The utility model provides a technical problem, the technical scheme who adopts is: a low-temperature drying refrigeration system comprises a refrigeration compressor, wherein an outlet of the refrigeration compressor is communicated with an a interface of an oil-liquid separator through a pipeline, a b interface of the oil-liquid separator is communicated with a c interface of a first tee joint through a pipeline, the a interface and the b interface of the first tee joint are respectively communicated with the a interface of a first condenser and the a interface of a second condenser through pipelines, and electromagnetic valves are respectively arranged on the two pipelines; the joint c of the tee joint II is communicated with the liquid storage tank through a pipeline.

The beneficial effects of the utility model are that, this utility model increases the check valve through the liquid return branch road between every condenser and tee bend, because the special construction of check valve, only can flow to the liquid storage pot in liquid flow to tee bend position from the condenser like this, can not get into another branch road again and get into another condenser. The other condenser can not be shut down due to the fact that excessive liquid generates excessive pressure when the other condenser works. Therefore, the problems of low production efficiency and unstable product quality caused by shutdown are solved. The liquid return filter is added at the front end of the check valve to prevent small foreign matters in the condenser from entering the check valve, so that the check valve is not closed tightly, and the liquid blocking effect is influenced.

Drawings

The following description is made in detail by way of example with reference to the accompanying drawings.

Fig. 1 is a schematic structural diagram of a refrigeration system of a low-temperature drying device.

In the figure: 1. the system comprises a refrigeration compressor, 2, an oil-gas separator, 3, a tee joint I, 4, an electromagnetic valve, 5, a condenser I, 6, a condenser II, 7, a liquid return filter, 8, a check valve, 9, a tee joint II, 10, a liquid storage tank and 11-pipelines.

Detailed Description

In order to make the technical solutions in the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts shall belong to the protection scope of the present invention.

The embodiment, referring to the attached drawings, discloses a low-temperature drying refrigeration system, which comprises a refrigeration compressor 1, wherein an outlet of the refrigeration compressor 1 is communicated with an a interface of an oil-liquid separator 2 through a pipeline 11, a b interface of the oil-liquid separator 2 is communicated with a c interface of a tee joint I3 through a pipeline 11, a and b interfaces of the tee joint I3 are respectively communicated with an a interface of a condenser I5 and a interface of a condenser II 6 through pipelines 11, and electromagnetic valves 4 are respectively arranged on the two pipelines 11; the joint c of the second tee joint 9 is communicated with a liquid storage tank 10 through a pipeline 11.

The utility model discloses a theory of operation is: high-temperature and high-pressure gas discharged by the compressor 1 enters the condenser I5 and the condenser II 6 through the oil-gas separator 2, the tee joint I3 and the electromagnetic valve 4; the high-temperature high-pressure gas is condensed into Freon liquid through the first condenser 5 and the second condenser 6, and the liquid flows back to the liquid storage tank 10 from the first condenser 5 and the second condenser 6 through the liquid return filter 7, the check valve 8 and the second tee joint 9.

Because the liquid return filter 7 and the check valve 8 are additionally arranged among the first condenser 5, the second condenser 6 and the second tee joint 9, the check valve 8 only allows liquid to flow in a single direction, so that the liquid can only flow to the liquid storage tank 10 from the position where the first condenser 5 and the second condenser 6 flow to the second tee joint 9 and cannot enter the other branch to enter the other condenser. The other condenser can not be shut down due to the fact that excessive liquid generates excessive pressure when the other condenser works.

Other embodiments of the present application will be apparent to those skilled in the art from consideration of the specification and practice of the application disclosed herein. This application is intended to cover any variations, uses, or adaptations of the invention following, in general, the principles of the application and including such departures from the present disclosure as come within known or customary practice within the art to which the invention pertains.
