Description

Technical Field

[0001] This application relates to the field of fluid ice making machine technology, and in particular to a fluid ice crystal concentration detection device. Background Technology

[0002] The mainstream method for assessing ice crystal density in the industry still relies primarily on manual visual inspection. The specific procedure typically involves taking a measured amount of fluid ice and placing it in a transparent container, observing the ice crystal density under natural light or auxiliary light, or judging the particle percentage by touch after stirring with a stirring rod. This method is susceptible to interference from multiple factors: firstly, differences in ambient light intensity directly affect the visual inspection results; secondly, variations in the operator's experience level and subjective judgment habits can easily lead to data deviations.

[0003] In practical applications, the data deviation of the same fluid ice sample often exceeds 10% when measured by different personnel, which makes it difficult to meet the requirements of precise quality control. Utility Model Content

[0004] To achieve the above objectives, this application proposes a fluidized ice crystal concentration detection device, comprising: a warm water system, an ice slurry water system, an ice melting and mixing system, and a signal processing system. The ice melting and mixing system is connected to the warm water system and the ice slurry water system respectively, and is configured to mix the liquids transported by the warm water system and the ice slurry water system.

[0005] The signal processing system is connected to the warm water system, the ice slurry water system, and the ice melting mixing system, and is configured to collect liquid parameters in each system.

[0006] The liquid parameters include temperature and flow rate.

[0007] In the above technical solution, the sensible heat of warm water is used to melt the ice crystals in the ice slurry. The measurement basis is established through the principle of energy conservation, and temperature and flow rate are collected to provide key input for the calculation of ice crystal rate.

[0008] Specifically, the ice melting and mixing system includes: a mixer; the first and second inlets of the mixer are respectively connected to a warm water system and an ice slurry system, and the mixer is configured to mix the warm water supplied by the warm water system and the ice slurry water supplied by the ice slurry system.

[0009] Specifically, the ice melting and mixing system also includes an observation mirror, which is installed at the outlet of the mixer to observe the mixing of warm water and ice slurry.

[0010] The mixing effect can be directly judged by observing the mirror, avoiding measurement errors caused by ice slurry clumping or interruption of warm water supply, and the warm water flow rate or temperature can be quickly adjusted according to the observed mixing effect.

[0011] Specifically, it also includes: regulating valves; the regulating valves are respectively installed at the inlet of the warm water system and the ice slurry water system, and are configured to regulate the flow rate of warm water / ice slurry water.

[0012] By using the above-mentioned technical means and by adjusting the flow rate of the two liquids with the help of the regulating valve, it is possible to adapt to the needs of different concentration detection scenarios and optimize the mixing ratio to improve detection accuracy.

[0013] Specifically, it also includes check valves; the check valves are respectively installed at the first and second inlets of the mixer, and are configured to prevent backflow.

[0014] Specifically, the warm water system includes: a heater; the heater is configured to heat the liquid in the warm water system.

[0015] With the above technical solution, if the water temperature is too low, the heater can be activated to raise the water temperature to meet the usage requirements.

[0016] Specifically, the signal processing system includes: temperature sensors; the temperature sensors are respectively installed at the outlets of the warm water system, the ice slurry water system, and the ice melting mixing system, and are configured to collect the liquid temperature.

[0017] Specifically, the signal processing system also includes: flow meters; the flow meters are respectively installed at the inlets of the warm water system and the ice slurry water system, and are configured to collect liquid flow rates.

[0018] Specifically, all connecting pipes in the warm water system and the ice slurry water system use pipes of the same size.

[0019] Specifically, the heater is installed on the outlet side of the flow meter, allowing users to determine whether to start the heater after the regulating valve has reached its maximum opening, thereby reducing overall power consumption.

[0020] Compared with the prior art, the advantages of this application are:

[0021] By using the heat balance method, ice slurry samples can be taken from the fluid ice storage device or the delivery pipeline. This not only allows for real-time monitoring of the ice crystal content of the fluid ice, but also avoids the problem of excessive deviation between the measurement results and the actual ice crystal content caused by traditional manual sampling and measurement.

In this regard, directional terms such as “top,” “bottom,” “left,” “right,” “up,” “down,” etc., are used with reference to the orientation of the described figures. Because components of the embodiments can be positioned in several different orientations, directional terms are used for illustrative purposes and are by no means limiting. It should be understood that other embodiments may be utilized or logical changes may be made without departing from the scope of the present application. Therefore, the following detailed description should not be taken in a limiting sense, and the scope of the present application is defined by the appended claims.

[0026] like Figure 1 As shown, in an optional embodiment, the device consists of a warm water system, an ice slurry water system, an ice melting mixing system, and a signal processing system 4.1; the warm water system and the ice slurry water system are respectively connected to the ice melting mixing system, and the signal processing system 4.1 collects the liquid parameters in each of the above systems, thereby measuring the ice crystal rate in the sampled ice slurry water using the heat balance method.

[0027] The main components in the warm water system include: a first regulating valve 1.1, a first check valve 1.5, and a first connecting pipe 1.6; the first regulating valve 1.1 is installed at the warm water inlet 1 to control the flow rate of the warm water, while the first check valve 1.5 is installed at the outlet of the warm water system to prevent liquid backflow, and the first connecting pipe 1.6 is used to connect the various valves in the warm water system.

[0028] The main components in the ice slurry water system include: a second regulating valve 2.1, a second check valve 2.4, and a second connecting pipe 2.5; the second regulating valve 2.1 is installed at the ice slurry water inlet 2 to control the flow rate of warm water, while the second check valve 2.4 is installed at the outlet of the warm water system to prevent liquid backflow, and the second connecting pipe 2.5 is used to connect the various valves in the warm water system.

[0029] The aforementioned warm water inlet 1 or ice slurry water inlet 2 can be supplied through the existing warm water / ice slurry water supply system or a separate water supply device, which greatly reduces the cost of equipment modification.

[0030] The main components of the ice melting and mixing system include: a mixer 3.1, an observation mirror 3.3, and a third connecting pipe 3.2. The mixer 3.1 has multiple inlets for connecting the warm water system and the ice slurry system respectively. The warm water and ice slurry are fully mixed in the mixer 3.1 and then discharged from the outlet. The observation mirror 3.3 is further placed at the outlet to facilitate the user's observation of whether there are residual ice crystals in the discharged liquid, so as to adjust the flow rate or temperature of the warm water in a timely manner.

[0031] The main components of the signal processing system 4.1 include a flow meter and a temperature sensor. In this embodiment, the first flow meter 1.3 and the first temperature sensor 1.4 are respectively installed at the outlet of the first outlet valve and the inlet of the first check valve 1.5 of the warm water system. The second flow meter 2.2 and the second temperature sensor 2.3 are respectively installed at the outlet of the second regulating valve 2.1 and the inlet of the second check valve 2.4 of the ice slurry water system. The third temperature sensor 3.4 is installed at the outlet of the observation mirror 3.3. The sensors are connected through the transmission line 4.2, thereby transmitting the collected data to the signal processing system 4.1.

[0032] Using the above settings, the following parameters were collected: warm water temperature T1, warm water flow rate Q1, ice slurry water temperature T2, ice slurry water flow rate Q2, and mixed water temperature T3. These collected data were then transmitted to the signal processing system, where the ice crystal ratio P was measured using the thermal balance method. The specific formula is as follows:

[0033]

[0034] Where C is the specific heat capacity of water, ρ is the density of water, T1 is the temperature of warm water, T2 is the temperature of ice slurry water, T3 is the temperature of fused water, V1 is the volume of warm water, and V2 is the volume of ice slurry water.

[0035] Furthermore, in this embodiment, since the first connecting pipe 1.6 and the second connecting pipe 2.5 use the same pipe diameter, it is only necessary to detect the liquid flow rate in the first connecting pipe 1.6 and the second connecting pipe 2.5 respectively to measure the liquid volume per unit time. Furthermore, the above formula can be simplified to...

[0036]

[0037] Where Q1 is the flow rate of warm water and Q2 is the flow rate of ice slurry water.

[0038] Based on the above embodiments, a more optimized design further includes: installing a heater 1.2 in the warm water system; by placing the heater 1.2 between the outlet of the check valve and the inlet of the first flow meter 1.3, the heater 1.2 can be activated to heat the water when the temperature is insufficient.

[0039] It is obvious that those skilled in the art can make various modifications and alterations to the embodiments of this application without departing from the spirit and scope of this application. In this way, this application also aims to cover such modifications and alterations if they fall within the scope of the claims and their equivalents. The word "comprising" does not exclude the presence of other elements or steps not listed in the claims. The simple fact that certain measures are described in mutually different dependent claims does not indicate that a combination of these measures cannot be used for profit. Any reference numerals in the claims should not be considered limiting in scope.
