Technical Field

[0001] The utility model relates to the technical field of chiller equipment, in particular to an air-cooled spiral chiller with a heating device. Background Art

[0002] Air-cooled spiral chillers are refrigeration equipment used in industrial and commercial air conditioning systems. They achieve refrigeration by compressing, condensing and expanding the refrigerant through a spiral compressor. Its air-cooling design uses air to dissipate heat without using a water cooling system. Air-cooled spiral chillers with heating devices are used in cold environments or when a certain temperature range needs to be maintained to prevent the cooling water from freezing and damaging the equipment, ensuring that the system continues to operate efficiently.

[0003] In most cases, the existing air-cooled spiral chillers use a water source that is directly connected to the inside of the machine for cooling during use. However, after long-term use, a large amount of scale will be generated inside the machine, which will cause damage to the machine. Although the prior art filters the water source through a replaceable activated carbon plate before use, the activated carbon plate still needs to be replaced or cleaned after long-term use. However, the prior art does not have a structure for cleaning the activated carbon plate, which increases the labor intensity of the staff and the practicality of the device is poor. Utility Model Content

[0023] Specifically, the belt 10 is driven to rotate continuously by starting the motor 4; the other end of the belt 10 is connected to the reciprocating screw 6, so that the outer wall hollow plate 8 reciprocates; this design allows the mechanical energy to be efficiently transmitted to the hollow plate 8, thereby driving the stirring blade 9 to rotate rapidly; at the same time, when the heating wire 7 is energized, heat is generated, so that the water in the heating box 2 is rapidly heated; during the rotation of the stirring blade 9, the cold water in the heating box 2 is rapidly stirred, so that the water temperature rises rapidly, thereby improving the heating efficiency; at the same time, the operation of the motor 4 not only drives the rotation of the stirring blade 9, but also drives the connecting rod 11 on the outer wall of the eccentric wheel 5 to reciprocate; the connecting rod 11 is connected to the sliding rod 1201, and the other end of the sliding rod 1201 is provided with a cleaning brush 1202; during the operation of the motor 4, the cleaning brush 1202 can quickly clean the impurities on the outer wall of the activated carbon plate 14; finally, this device is also equipped with a collection box 19, which can effectively collect and treat impurities in the water source; this not only ensures the cleanliness of the water quality, but also reduces the cleaning cost of the activated carbon plate 14.

[0024] Reference Figure 1 , Figure 2 and Figure 3, an air-cooled chiller body 15 is fixedly connected to the upper surface of the bottom plate 1, and a fixed plate 16 is fixedly connected to the outer wall of the air-cooled chiller body 15; a support leg 17 is fixedly connected to the upper surface of the fixed plate 16, and the support leg 17 is fixedly connected to the filter box 13; a funnel 18 is provided on the lower surface of the filter box 13, and the funnel 18 is fixedly connected to the air-cooled chiller body 15; a controller 20 is fixedly connected to the upper surface of the bottom plate 1, a water pump 21 is fixedly connected to one side of the outer wall of the air-cooled chiller body 15, a connecting pipe 22 is fixedly connected to the input end of the water pump 21, and a spiral tube 23 is fixedly connected to the output end of the water pump 21; one end of the connecting pipe 22 is penetrated and arranged inside the heating box 2, and the spiral tube 23 is fixedly connected to the outer wall of the air-cooled chiller body 15; a condenser 25 is fixedly connected to the upper surface of the bottom plate 1, and a connecting pipe 24 is fixedly connected to the inside of the condenser 25, one end of the connecting pipe 24 is fixedly connected to the spiral tube 23, and the other end of the connecting pipe 24 is penetrated and arranged inside the heating box 2;

[0025] Specifically, first, by starting the water pump 21, the hot water inside the heating box 2 is quickly transferred to the inside of the connecting pipe 22; the purpose of this step is to deliver the hot water to the outer wall of the air-cooled chiller body 15 as soon as possible so as to heat it; the design of the connecting pipe 22 should ensure smooth flow of water to avoid resistance loss; next, the hot water is transferred to the inside of the spiral tube 23 by the water pump 21; the design of the spiral tube 23 is conducive to enhancing the flow stability of the hot water, so that it can achieve a fast and uniform heating effect during the transmission process; in this way, the outer wall of the air-cooled chiller body 15 can achieve the required heating effect in a short time; during the heating process, when the temperature inside the heating box 2 is high, the condenser 25 can be controlled by the controller 20; after the condenser 25 is turned on, the hot water will cool down rapidly when passing through the condenser 25, thereby avoiding overheating; this design enables the air-cooled chiller to achieve efficient operation in both heating and cooling processes, thereby improving the service life and energy efficiency of the equipment.

[0026] Working principle: when the unit needs to be heated, the belt 10 is driven by the motor 4 to drive the reciprocating screw rod 6 and the outer wall hollow plate 8 to reciprocate, and the movement of the hollow plate 8 can quickly drive the stirring blade 9 to rotate, and the heating wire 7 is turned on at the same time to heat the water inside the heating box 2, and the stirring blade 9 can quickly stir and heat the cold water inside the heating box 2, and the motor 4 drives the outer wall connecting rod 11 of the eccentric wheel 5 to reciprocate, and the connecting rod 11 drives the sliding rod 1201 to make the cleaning brush 1202 quickly clean the impurities on the outer wall of the activated carbon plate 14, and the collection box 19 can collect and process the impurities in the water source;

[0027] Secondly, after the water source inside the heating box 2 is quickly heated, the hot water inside the heating box 2 is quickly transferred to the inside of the connecting pipe 1 22 by starting the water pump 21, and then transferred to the inside of the spiral tube 23 by the water pump 21. The spiral tube 23 quickly and evenly transfers the hot water to the outer wall of the air-cooled chiller body 15 for heating treatment. At this time, it flows back to the inside of the heating box 2 through the connecting pipe 24 for reheating. When the temperature inside the heating box 2 is high, the condenser 25 is controlled to be turned on by the controller 20, and the hot water is quickly cooled down by the condenser 25, thereby achieving the effect of easy temperature control.
