Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ice machine refrigeration, in particular to an ice machine refrigeration stable working device. Background Art
[0002] Ice machines are refrigeration equipment used to make and keep ice cubes. In industrial and commercial environments, ice machines are widely used in various occasions, such as food industry, fishery, pharmaceutical industry, construction industry, supermarkets and catering industry. The working principle of ice machines is based on the refrigeration cycle, which includes four main processes: evaporation, compression, condensation and throttling. In this process, the refrigerant plays a key role. It circulates between different components, absorbing and releasing heat, thereby achieving the cooling effect.
[0003] In actual production, ice machines often work in conjunction with condensers. In existing devices, due to the high pressure in the liquid storage tank, the Freon in the methanol condenser and the circulating water condenser is difficult to enter the liquid storage tank, resulting in a shortage of Freon in the ice machine and a decrease in working efficiency. However, if excessive Freon is added, it will cause the tank to overflow after shutdown. Moreover, since the reactor requires stable cooling conditions when working, once the efficiency of the ice machine decreases, it will have a very adverse effect on production. Utility Model Content
[0004] In view of the above deficiencies in the prior art, the purpose of the utility model is to provide a stable refrigeration working device for an ice machine, by using a liquid storage tank balance pipe, a methanol condenser balance pipe and a circulating water condenser balance pipe in coordination, the pressures in the methanol condenser, the circulating water condenser and the liquid storage tank are balanced, thereby avoiding the problem of difficulty in filling the liquid into the liquid storage tank and ensuring the normal operation of the ice machine; by setting a circulating water temporary storage tank, a variable frequency pump inlet pipe and a liquid outlet pipe at the bottom of the circulating water temporary storage tank, part of the circulating water is stored in the circulating water temporary storage tank, thereby avoiding the influence on normal production when the ice machine is working unstably.
[0005] The utility model is realized by adopting the following technical solutions:
[0006] The ice machine refrigeration stable working device comprises a methanol condenser, a circulating water condenser and a liquid reservoir. The methanol condenser is connected to the liquid reservoir through a Freon inlet liquid reservoir pipeline, the liquid reservoir is connected to the ice machine through a circulating pump, the circulating water condenser is connected to the reactor through a circulating water temporary storage tank, a liquid reservoir balancing pipeline is connected to the liquid reservoir, the methanol condenser is connected to the liquid reservoir balancing pipeline through the methanol condenser balancing pipeline, and the circulating water condenser is connected to the liquid reservoir balancing pipeline through the circulating water condenser balancing pipeline.
[0007] The Freon in the methanol condenser and the circulating water condenser first enters the liquid storage tank, then enters the ice machine for processing, and finally returns to the methanol condenser and the circulating water condenser, forming a cycle. The circulating water in the circulating water condenser passes through the circulating water temporary storage tank, then enters the reactor coil in the reactor through the variable frequency pump, and finally returns to the circulating water condenser through the return pipe, forming a cycle.
[0008] The methanol condenser is connected with a methanol inlet pipeline, and the methanol condenser is connected with a methanol temporary storage tank through a pipeline.
[0009] A methanol condenser balancing port is provided between the methanol condenser and the methanol condenser balancing pipe, and a circulating water condenser balancing port is provided between the circulating water condenser and the circulating water condenser balancing pipe.
[0010] A liquid storage balancing port is arranged between the liquid storage and the liquid storage balancing pipeline, and the circulating water condenser is connected with the liquid storage through the Freon liquid storage pipeline.
[0011] The ice machine is connected to the methanol condenser through a Freon ice machine pipeline, and the Freon ice machine pipeline is connected to the circulating water condenser through a pipeline.
[0012] A reactor coil is arranged inside the reactor, and a circulating water temporary storage tank is connected to the reactor coil via a variable frequency pump.
[0013] A variable frequency pump inlet pipeline is connected between the circulating water temporary storage tank and the variable frequency pump. The circulating water temporary storage tank is connected to the variable frequency pump inlet pipeline through the bottom outlet pipeline of the circulating water temporary storage tank, and the reactor coil is connected to the circulating water condenser through the return pipeline.
[0014] The inlet variable frequency pump pipeline is set at a high position, a liquid level gauge is provided on the circulating water temporary storage tank, and the outlet pipeline at the bottom of the circulating water temporary storage tank is located at the bottom of the circulating water temporary storage tank. After the circulating water enters the circulating water temporary storage tank, it first enters the variable frequency pump through the inlet variable frequency pump pipeline. Only when the refrigeration efficiency of the ice machine becomes low or the temperature of the reactor rises suddenly, the valve on the outlet pipeline at the bottom of the circulating water temporary storage tank is opened, the power of the variable frequency pump is increased, and the reactor is cooled down.
[0015] The working principle of the utility model is:
[0016] The Freon in the ice machine enters the methanol condenser and the circulating water condenser through the Freon ice machine pipeline. Methanol and circulating water also exchange heat with each other in the methanol condenser and the circulating water condenser respectively. After that, the Freon enters the liquid storage tank and then returns to the ice machine for processing. The liquid storage balance pipeline, the methanol condenser balance pipeline and the circulating water condenser balance pipeline are always in a connected state; methanol enters the methanol temporary storage tank through the pipeline, and the circulating water in the circulating water condenser enters the reactor coil in the reactor through the variable frequency pump after passing through the circulating water temporary storage tank, and finally returns to the circulating water condenser through the return pipeline; when the refrigeration efficiency of the ice machine becomes low or the temperature of the reactor rises suddenly, open the valve on the liquid outlet pipeline at the bottom of the circulating water temporary storage tank, increase the power of the variable frequency pump, and cool the reactor. Among them, the Freon in the methanol condenser and the circulating water condenser first enters the liquid storage tank, then enters the ice machine for processing, and finally returns to the methanol condenser and the circulating water condenser, forming a cycle.
