Description

Cooling system and draught beer machine

Technical Field

The invention relates to the technical field of cooling equipment, in particular to a cooling system and a draught beer machine.

Background

The draught beer machine is also called beer selling device, it is composed of refrigerating machine, draught beer barrel and carbon dioxide gas cylinder, its working principle is that the high-pressure carbon dioxide gas in the carbon dioxide gas cylinder is used to press out the beer in the draught beer barrel, so that the beer enters the refrigerating machine and then flows out from the beer outlet. The beer passing through the beer machine has cool taste.

Draft beer machines are classified into two types, water-cooled and direct-cooled, in terms of refrigeration methods. The water cooling type is that beer circulates in a draught beer machine filled with water through a beer pipe, and the draught beer is reduced along with the reduction of water temperature, so that the refrigeration effect is achieved; direct cooling, as the name implies, direct refrigeration of beer. The beer is fed into the draught beer machine through the pressure of carbon dioxide, and the refrigeration pipes are fully distributed around the draught beer machine, so that the temperature in the box body is reduced, and the temperature of the beer is reduced. The refrigerating principle of the draught beer machine is as follows: refrigerant in the compressor cools down through pipeline (the pipeline is the gas through compressing in, the temperature is higher) to the condenser pipe through the pressure effect, and later drier-filter carries out filtration and drying process, and pure gas releases the production air conditioning in the condenser pipe in the twinkling of an eye after being pressurizeed by tiny capillary. The loop pipe recovers the gas to the compressor for recycling. Beer (beverage) enters the refrigerating pipe from one end of the pipeline connected with the wine barrel, flows in the spiral pipeline, is rapidly cooled and then flows out from the pipeline connected with the wine column to achieve the cooling effect.

However, the traditional refrigeration mode, such as water cooling, has a slow refrigeration speed, and after a draught beer valve is opened, the cooled beer generally falls after receiving a few cups of beer, so that the cooled beer can be continuously discharged after waiting for a while, which takes a long time.

Referring to fig. 1 and 2, fig. 1 is a partial sectional view of a cooling system according to an embodiment of the present invention; fig. 2 is a sectional view showing a feed pipe 1 and a refrigerant pipe 2 according to an embodiment of the present invention.

The embodiment provides a cooling system, which comprises a refrigerating assembly, a conveying pipe 1 and a refrigerating pipe 2, wherein the refrigerating assembly is communicated with the refrigerating pipe 2; the transport pipe 1 passes through the refrigeration pipe 2, and both ends of the transport pipe 1 are disposed outside the refrigeration pipe 2.

When the beer dispensing device is actually used, one end of the conveying pipe 1 is connected with a beer barrel of a draught beer machine, and the other end of the conveying pipe 1 is connected with a beer valve of the draught beer machine; because refrigeration subassembly and above-mentioned refrigeration pipe 2 intercommunication, so the refrigerant of refrigeration subassembly output gets into in refrigeration pipe 2 and contacts with conveyer pipe 1, and conveyer pipe 1 is arranged in the part of refrigeration pipe 2 and is wrapped up by the refrigerant completely, so the accessible refrigerant is cooled down conveyer pipe 1 fast, cools off the beer of conveyer pipe 1 inside flow, and is efficient, weak point consuming time. The beer discharged from the beer valve is low in temperature, and cooled beer can be discharged continuously. And this cooling system can be opened at will and use, can cut off the power supply when not using, compares in traditional water-cooled draught beer machine, and energy-conservation is more than 50%.

As shown in fig. 1 to 2, in some embodiments of the present invention, the cooling pipe 2 further includes a baffle 4, both ends of the cooling pipe are sealed by the baffle 4, and the conveying pipe 1 passes through the baffle 4.

According to the invention, the baffle 4 is arranged, the two ends of the refrigerating pipe 2 are sealed by the baffle 4, the conveying pipe 1 penetrates through the baffle 4, so that the refrigerant is sealed in the refrigerating pipe 2, the refrigerant is prevented from overflowing from the refrigerating pipe 2, and the refrigerating efficiency is improved.

As shown in fig. 1-2, in some embodiments of the present invention, the present invention further comprises a circulation pipe 3, one end of the circulation pipe 3 is communicated with one end of the refrigeration pipe 2, and the other end of the circulation pipe 3 is communicated with the refrigeration assembly; the refrigerating assembly is communicated with the other end of the refrigerating pipe 2.

The invention sets a circulating pipe 3, one end of the circulating pipe 3 is communicated with one end of the refrigerating pipe 2, the other end of the circulating pipe 3 is communicated with the refrigerating component; the refrigerating assembly is communicated with the other end of the refrigerating pipe 2, so that the refrigerant after cooling the conveying pipe 1 can enter the circulating pipe 3 and enter the refrigerating assembly along the circulating pipe 3 for continuous use, and the refrigerant of the whole cooling system can circularly flow to refrigerate.

As shown in fig. 1-2, in some embodiments of the present invention, the refrigeration assembly includes a compressor 5 and a condenser 6 which are sequentially communicated, and an end of the circulation pipe 3 remote from the refrigeration pipe 2 is communicated with an air inlet of the compressor 5; one end of the condenser 6 is communicated with the air outlet of the compressor 5, and the other end of the condenser 6 is communicated with the refrigerating pipe 2.

The compressor 5 is a driven fluid machine that raises low-pressure gas into high-pressure gas, and is a heart of a refrigeration system. The refrigerating cycle is powered by sucking low-temperature and low-pressure refrigerant gas from the air suction pipe, driving the piston to compress the refrigerant gas through the operation of the motor, and discharging high-temperature and high-pressure refrigerant gas to the exhaust pipe. Thereby realizing a refrigeration cycle of compression → condensation (heat release) → expansion → evaporation (heat absorption). The compressor 5 is divided into a piston compressor 5, a screw compressor 5, a centrifugal compressor 5, a linear compressor 5, and the like. The working principle of the compressor 5 is as follows: the compressor 5 is directly driven by the motor to rotate the crankshaft and drive the connecting rod to reciprocate the piston, resulting in volume change of the cylinder. Because of the change of the pressure in the cylinder, the air enters the cylinder through the air filter (muffler) by the air inlet valve, during the compression stroke, the compressed air enters the air storage tank through the exhaust pipe and the check valve by the action of the exhaust valve due to the reduction of the volume of the cylinder, and when the exhaust pressure reaches the rated pressure of 0.7MPa, the automatic stop is performed by the pressure switch control. When the pressure of the gas storage tank is reduced to 0.5-0.6 MPa, the pressure switch is automatically connected and started.

The condenser 6 is a component of a refrigeration system, belonging to the type of heat exchanger, which is capable of converting a gas or vapor into a liquid, transferring the heat in the tubes to the air in the vicinity of the tubes in a rapid manner. The condenser 6 is operated as an exothermic process, so that the condenser 6 is heated to a high temperature. Principle of the condenser 6: the gas passes through a long tube (usually coiled into a solenoid) to dissipate heat into the surrounding air, and metals such as copper, which are highly thermally conductive, are commonly used to transport vapor. In order to improve the efficiency of the condenser 6, radiating fins with excellent heat conduction performance are often added on the pipeline, the radiating area is enlarged to accelerate the heat dissipation, and the air convection is accelerated through a fan to take away the heat. The refrigeration principle of a general refrigerator is that a compressor 5 compresses a working medium from low-temperature low-pressure gas into high-temperature high-pressure gas, the high-temperature high-pressure gas is condensed into medium-temperature high-pressure liquid through a condenser 6, and the medium-temperature high-pressure liquid is throttled by a throttle valve and becomes low-temperature low-pressure liquid. The low-temperature low-pressure liquid working medium is sent into the evaporator, absorbs heat in the evaporator and evaporates to become low-temperature low-pressure steam, and the low-temperature low-pressure steam is sent into the compressor 5 again, so that the refrigeration cycle is completed.

The invention comprises a compressor 5 and a condenser 6 which are communicated in sequence by arranging a refrigeration component, wherein one end of the circulating pipe 3, which is far away from the refrigeration pipe 2, is communicated with an air inlet of the compressor 5; one end of the condenser 6 is communicated with the air outlet of the compressor 5, and the other end of the condenser 6 is communicated with the refrigerating pipe 2. This facilitates the compression of the refrigerant by the compressor 5 and the delivery thereof to the condenser 6 for cooling, thus facilitating the heat exchange of the refrigerant.

As shown in fig. 1 to 2, in some embodiments of the present invention, a dry filter 7 is disposed between the condenser 6 and the refrigerating pipe 2, one end of the dry filter 7 is communicated with the condenser 6, and the other end of the dry filter 7 is communicated with the refrigerating pipe 2.

Because the refrigeration pipe 2 needs to be vacuumized when in use, and the refrigerant is used in a vacuum environment, the invention prevents the compressor 5 from absorbing moisture and preventing ice blockage under the condition of insufficient vacuumizing by arranging the drying filter 7, wherein one end of the drying filter 7 is communicated with the condenser 6, and the other end of the drying filter 7 is communicated with the refrigeration pipe 2.

As shown in fig. 1 to 2, in some embodiments of the present invention, a cooling pipe 8 is disposed between the dry filter 7 and the cooling pipe 2, and the dry filter 7 and the cooling pipe 2 are communicated through the cooling pipe 8.

In the present invention, a cooling pipe 8 is provided between the dry filter 7 and the cooling pipe 2, and the dry filter 7 and the cooling pipe 2 are communicated with each other through the cooling pipe 8. This facilitates the conveyance of the refrigerant passing through the dry filter 7 into the cold transfer pipe 8, and then into the refrigerant pipe 2 through the cold transfer pipe 8.

As shown in fig. 1 to 2, in some embodiments of the present invention, the number of the delivery pipes 1 is plural, and a plurality of the delivery pipes 1 are arranged in parallel and at intervals.

According to the beer cooler, the conveying pipes 1 are arranged in number, the conveying pipes 1 are arranged in parallel at intervals, and gaps are formed among the conveying pipes 1 arranged at intervals, so that a refrigerant can be conveniently filled in the gaps to wrap the conveying pipes 1, the conveying pipes 1 can be conveniently cooled, and the cooling efficiency of beer is improved.

As shown in fig. 1-2, in some embodiments of the present invention, the outer side wall of the refrigeration pipe 2 is provided with a thermal insulation layer 9.

The outer side wall of the refrigeration pipe 2 is provided with a heat insulation layer 9. Therefore, the heat exchange between the refrigerant in the refrigerating pipe 2 and the outside is prevented, the loss of cold energy is prevented, and the cooling efficiency of beer is further improved.

The heat-insulating material is generally a light, loose, porous and fibrous material. It can be divided into organic materials and inorganic materials according to its composition. The former has better heat insulation performance than the latter, but the latter has better durability than the former. The heat conductivity coefficient is a main index for measuring the performance of the heat-insulating material. The smaller the thermal conductivity, the smaller the amount of heat transferred through the material, the better the thermal insulation performance, the thermal conductivity of the material is determined by the composition, internal structure, volume weight, etc. of the material, and also the average temperature during heat transfer and the water content of the material. Generally speaking, the lighter the volume weight, the lower the thermal conductivity. Alternatively, the thermal insulation layer 9 of the present embodiment can be made of a light thermal insulation material, such as a foam board.

As shown in fig. 1-2, in some embodiments of the present invention, the delivery tube 1 is a copper tube.

The copper pipe is high in structural strength, high in heat conducting performance and convenient to transfer heat, and the conveying pipe 1 is arranged to be the copper pipe, so that beer in the conveying pipe 1 and a refrigerant outside the conveying pipe 1 can conveniently complete heat exchange, and refrigeration efficiency is improved.
