Description

Technical Field

[0001] This utility model relates to the field of energy equipment technology, and in particular to a high-efficiency ice production device. Background Technology

[0002] Dynamic ice storage technology refers to the direct heat exchange between refrigerant and water, causing the water to crystallize into flocculent ice crystals. Simultaneously, the formation and melting processes do not require secondary heat exchange, thus significantly improving the energy efficiency of air conditioning. The pores of the ice slurry are much larger than those of solid ice, and it directly exchanges heat with the return water, resulting in excellent load response performance. As an important means to effectively alleviate the problem of intermittent imbalances in power load, dynamic ice storage technology has received widespread attention in recent years. During the operation of the refrigeration system, dynamic ice storage technology uses a special ice-making method to generate and store cold energy in a dynamic flow state. Compared to traditional static ice storage technology, dynamic ice storage technology has significant advantages in peak shaving, valley filling, energy saving, and cost reduction.

[0003] Conventional industrial ice-making methods utilize the fact that the freezing point of a salt solution is lower than that of water. A refrigeration system cools the brine, and then water is added to the salt solution, where it freezes into ice at a low temperature. A certain concentration of salt solution is added to the ice-making tank, and the refrigeration system is activated to lower the temperature of the salt solution to about -10°C to -15°C. Then, through heat exchange between the water and the low-temperature salt solution, the water in the mold is gradually cooled and frozen to produce finished ice blocks. Although this ice-making technology can quickly produce large quantities of ice blocks, it requires a lot of energy to lower the temperature of the salt solution to about -10°C to -15°C, which is not conducive to energy conservation and reducing production costs. Utility Model Content

[0004] Purpose of the utility model: The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a high-efficiency ice production device with reasonable structural design, wide application range, convenient operation, and environmental protection and energy saving. While using dynamic ice storage, the floating ice or ice-water mixture generated by the ice storage system can be reused. Through an additional hydraulic device, economically viable finished ice blocks can be produced. It has a wide range of applications and contains considerable economic benefits. A highly promising open source approach is quietly emerging, with important economic and social value.

[0005] Technical solution: To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows:

[0006] A high-efficiency ice production device includes a dynamic ice-making device, an ice-water circulation pump, an ice-water mixing tank, a screw conveyor pump, a filter press, an ice-water recovery pump, a conveyor belt, an ice slag hopper, a hydraulic device, a refrigeration circulating fluid pipeline, an ice-making circulating water pipeline, a tap water supply pipeline, an ice-pressing recovery water pipeline, ice slag, and finished ice blocks.

[0007] As a preferred embodiment, in the above-described high-efficiency ice production device, the dynamic ice-making device is connected to the ice-water mixing tank via an ice-making circulating water pipeline to form a cycle that outputs dynamic ice, and an ice-water circulating pump is installed on the pipeline; the dynamic ice-making device is connected to a freezing circulating liquid pipeline, the medium of which is ethylene glycol antifreeze, which exchanges heat with the ice-making circulating water in the dynamic ice-making device to complete the dynamic ice-making cycle.

[0008] As a preferred embodiment, in the above-described high-efficiency ice production device, the ice-water mixing tank uses a screw conveyor pump to transport floating ice or ice-water mixture from the top of the tank to a filter press, and replenishes the water lost due to the production of dynamic ice through a tap water supply pipeline; the filter press sends the filtered recycled water back to the ice-water mixing tank through an ice-recycled water pipeline, and an ice-water recycling pump is installed on the pipeline.

[0009] As a preferred embodiment, in the above-described high-efficiency ice production device, the filter press draws in floating ice or an ice-water mixture through the inlet hole in the middle of the machine, filters it through the filter element, and then flows out through the drain holes around the machine (this step can significantly reduce the water content). The filtered ice water is then pumped by a recycling pump to an ice-water mixing tank for reuse.

[0010] As a preferred embodiment, in the above-described high-efficiency ice production device, the filter press conveys the filtered ice slag to the ice slag hopper via a conveyor belt; the ice slag is then conveyed from the ice slag hopper to a hydraulic device, where it is physically hydraulically formed into finished ice blocks.

[0011] This utility model provides a high-efficiency ice production device. The working principle of the dynamic ice-making device is as follows: Using a common subcooled water dynamic ice-making method, water is first cooled to a subcooled state below 0°C in a subcooling heat exchanger. At this point, the water is in a metastable state; although the temperature is below the freezing point, it has not yet frozen. Then, the subcooled water is transported to a special subcooling decooler, where the subcooling state is relieved through mechanical disturbance, ultrasound, and the addition of seed crystals, instantly generating a large number of fine ice crystal particles, which, together with the remaining liquid water, form an ice slurry below 0°C.

[0012] When the system is running, the dynamic ice-making device produces ice slurry and transports it to the ice-water mixing tank through the ice-making circulating water pipe. Due to the density effect, the upper part of the tank is floating ice and the lower part is ice water. The ice water circulating pump installed in the pipeline draws in the lower ice water and sends it to the dynamic ice-making device to complete the dynamic ice-making cycle.

[0013] The floating ice in the upper part of the water tank is pumped out by a screw conveyor pump and sent to a filter press. In the filter press, the water content of the ice-water mixture, including the floating ice, is greatly reduced. The pressed ice water is recovered by an ice water recovery pump and transported to an ice water mixing tank through an ice water recovery pipeline for reuse.

[0014] After being processed by the filter press, the ice slag is conveyed to the ice slag hopper via a conveyor belt. A hydraulic device is then used to perform the final filtration, shaping, and other processes on the ice slag before outputting the finished ice blocks.

[0015] This utility model has the following beneficial effects:

[0016] Compared with existing technologies, the high-efficiency ice production device provided by this utility model has the following advantages: The high-efficiency ice production device provided by this utility model has a reasonable structural design, a wide range of applications, and is easy to operate. It can make full use of energy, is green and environmentally friendly, and is easy to promote. While using dynamic ice storage, the floating ice or ice-water mixture generated by the ice storage system can be reused. Through an additional hydraulic device, economically viable finished ice blocks can be produced. It has a wide range of applications and contains considerable economic benefits. A highly promising open source approach is quietly emerging, which has important economic and social value. Attached Figure Description
