Description

Technical Field

[0001] The present invention relates to the technical field of ice slurry preparation, and in particular to a method and system for preparing high-viscosity ice slurry. Background Art

[0002] Ice slurry cleaning technology is a novel pipeline cleaning technology in the water supply network industry. A certain concentration of ice slurry is pumped into the water supply pipeline to form an ice plug, and then the water in the water supply network is used to push the ice plug to flow for pipeline cleaning. Ice slurry exhibits the shear properties of solid particles and the flow properties of liquids. It can exert a higher shear force on the pipe wall than traditional water flow cleaning and can be used in pipeline cleaning operations safely, efficiently, energy-saving and environmentally friendly.

[0003] How to further improve the viscosity of ice slurry, increase the shear force of ice slurry, and enhance the cleaning effect is the current research direction. At present, ice slurry is mostly made of salt as a freezing point inhibitor mixed with water. The salt water is highly corrosive, which leads to an increase in the failure rate of equipment for preparing and storing ice slurry. In addition, when ice slurry is used to clean metal pipes, there is a risk of corrosion of metal pipes. In summary, it is necessary to develop a high-viscosity, low-corrosive ice slurry suitable for cleaning food and water supply pipes. Summary of the invention

Stop stirring and let the emulsion stand to room temperature. The emulsion is pumped from the storage tank into the fluidized ice machine to make ice, and the made ice is then discharged into the emulsion storage tank, and the cycle is repeated to prepare ice slurry with an ice content of 20%-40%.

[0008] As a preferred solution of the method for preparing high-viscosity ice slurry of the present invention, the volume ratio of water to edible oil is 7:3-8:2.

[0009] As a preferred embodiment of the method for preparing high-viscosity ice slurry of the present invention, the stirring speed of the high-speed stirring is maintained at 150-300 r / min, and the stirring speed of the low-speed stirring is maintained at 100-200 r / min.

[0010] As a preferred embodiment of the method for preparing high-viscosity ice slurry of the present invention, during the preparation of the ice slurry, the agitator of the emulsion storage tank performs a third stirring at a rotation speed of 100-200 r / min.

[0011] The present invention also includes a high-viscosity ice slurry preparation system, comprising: A refrigeration assembly, including a condensing heat exchanger, a partitioning heat exchanger connected to an outlet of the condensing heat exchanger, and a slurry ice machine; An ice-making solution circulation assembly, comprising a circulation pipeline and a circulation pump body connected to the circulation pipeline; The ice storage system comprises a mixing and stirring chamber, a variable speed stirring component arranged in the mixing and stirring chamber, and a storage tank connected to the mixing and stirring chamber.

[0012] As a preferred solution of the high-viscosity ice slurry preparation system of the present invention, the shell side outlet of the partition wall heat exchanger is connected to the air intake of the compressor through a circulation pipeline, and the compressor exhaust port is connected to the inlet of the condensing heat exchanger through a circulation pipeline.

[0013] As a preferred solution of the high-viscosity ice slurry preparation system of the present invention, a circulation pipeline is provided between the mixing and stirring chamber and the storage tank, and the circulation pump body is arranged on the circulation pipeline. The circulation pump body is used to transport the emulsion from the storage tank to the slurry ice machine for ice making, and the made ice is then discharged into the emulsion storage tank through the circulation pump body for circulation preparation.

[0014] As a preferred solution of the system for preparing high-viscosity ice slurry described in the present invention, the variable speed stirring component includes a stirring rod arranged in a mixing and stirring chamber, a stirring blade arranged at the lower end of the stirring rod, and a speed regulating component arranged on the stirring rod, the speed regulating component is used to change the rotation speed of the stirring blade, the stirring rod is rotatably connected to the upper end of the mixing and stirring chamber, and the mixing and stirring chamber is provided with a feed port and a discharge port, and the height of the discharge port is lower than the height of the feed port.

[0017] Beneficial effects of the present invention: Compared with the existing ice slurry, the ice slurry prepared by the above method has the same latent heat of ice slurry made of two oils, so the ice slurry concentration is low, and the overall latent heat of melting of the ice slurry is low. Therefore, in order to increase the latent heat of melting of the ice slurry, it is necessary to increase the concentration of the ice slurry. At the same time, in order to ensure that the ice slurry does not affect the fluidity due to excessive viscosity, soybean oil and MCT oil can be mixed in a certain proportion as a freezing point inhibitor to make ice slurry. The larger the volume proportion of MCT oil, the lower the viscosity of the ice slurry (at the same ice slurry concentration). When the volume proportion of MCT oil is 40%, that is, the volume ratio of soybean oil: MCT oil is 6:4, the viscosity of the ice slurry is almost the same as the viscosity of the ice slurry made with pure MCT oil as the freezing point inhibitor (at the same ice slurry concentration).

[0018] The preparation system can adjust the rotation speed of the stirring blades. The higher the speed at the input end, the higher the speed at the output end, which makes it easier to adjust the speed at the output end. If the speed needs to be reduced, only the speed at the input end needs to be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings. Example 1

[0027] Reference Figure 1 , provides a method for preparing high-viscosity ice slurry, comprising the following steps: Water and edible oil are mixed according to a certain proportion, and a food emulsifier polyglycerol-10 polyricinoleate having a volume fraction of 0.01%-0.1% of the total volume of water and edible oil is prepared, and the above raw materials are mixed to form an emulsion, wherein the volume ratio of water to edible oil is 7:3-8:2. When the ratio of water to edible oil is between 7:3-8:2, the effect of the produced ice slurry is similar, so when the ratio of water to edible oil is 8:2, the cost of ice making can be further reduced.

[0028] Then, the emulsions are mixed and heated to 50°C-70°C, and stirred at high speed for 10-30 minutes, while water of the same temperature is slowly and intermittently added.

[0029] Reduce the stirring speed and continue stirring for 10-20 minutes until the emulsion is completely uniform, then stop stirring and let the emulsion stand to room temperature. The stirring speed of the high-speed stirring is maintained at 150-300 r / min, and the stirring speed of the low-speed stirring is maintained at 100-200 r / min.

[0030] The viscosity of the emulsion and ice slurry prepared using soybean oil as a freezing point depressant is higher than that of the emulsion and ice slurry prepared using MCT oil. Therefore, when using soybean oil as a freezing point depressant to prepare an emulsion, a higher agitator speed (such as 400 r / min) and a longer stirring time (such as 30 min) are required to prepare an emulsion using soybean oil as a raw material. When preparing an ice slurry from a soybean oil emulsion, a higher speed (such as 200 r / min) is also required to prevent agglomeration due to the high viscosity and thickness of the ice slurry. A higher speed can ensure that the ice slurry particles are milky white, granular, and have good flow dispersion, and it helps prevent the ice slurry particles from adhering to the wall of the ice slurry preparation container.

[0031] Compared with soybean oil, the preparation of MCT oil emulsion and slurry can use a lower stirrer speed and the stirring time can be appropriately shortened.

[0032] The emulsion is pumped from the storage tank 302 into the slurry ice machine 103 to make ice, and the made ice is discharged into the emulsion storage tank 302, and the ice slurry with an ice content of 20%-40% is prepared in this cycle. The ice slurry is transported by a pump, so the viscosity of the ice slurry should not be too large. The concentration of the ice slurry made of soybean oil is preferably 20%-30%, and the concentration of the ice slurry made of MCT oil is preferably 30%-40%, so as to ensure fluidity while maximizing the friction on the pipe wall of the cleaned pipe.

[0033] Furthermore, in this embodiment, the pump is preferably a peristaltic pump, because the peristaltic pump can transport liquids or substances with a certain viscosity.

[0034] Preferably, during the ice slurry preparation process, the agitator of the emulsion storage tank 302 performs a third stirring at a rotation speed of 100-200 r / min.

[0035] Compared with the existing ice slurry, the ice slurry prepared by the above method has the same latent heat of ice slurry made of two kinds of oils. Therefore, the ice slurry concentration is low, and the overall latent heat of melting of ice slurry is low. Therefore, in order to increase the latent heat of melting of ice slurry, it is necessary to increase the concentration of ice slurry. At the same time, in order to ensure that the ice slurry does not affect the fluidity due to excessive viscosity, soybean oil and MCT oil can be mixed in a certain proportion as a freezing point inhibitor to make ice slurry. The larger the volume proportion of MCT oil, the lower the viscosity of the ice slurry (at the same ice slurry concentration). When the volume proportion of MCT oil is 40%, that is, the volume ratio of soybean oil: MCT oil is 6:4, the viscosity of the ice slurry is almost the same as that of the ice slurry made with pure MCT oil as a freezing point inhibitor (at the same ice slurry concentration).

[0036] (Note: Because MCT oil is more expensive than soybean oil, this method of preparing ice slurry with mixed edible oils can increase the concentration of ice slurry while controlling costs without increasing the viscosity of the ice slurry.) Example 2

[0037] Reference Figure 2-7 , provides a method for preparing high-viscosity ice slurry, including a refrigeration component 100. In this embodiment, the refrigeration component 100 includes a condensing heat exchanger 101, a partition heat exchanger 102 connected to the outlet of the condensing heat exchanger 101, and a slurry ice machine 103.

[0038] Furthermore, the present invention also includes an ice-making solution circulation component 200, including a circulation pipe 201 and a circulation pump body 202 connected to the circulation pipe 201, and an ice storage system 300. In this embodiment, the ice storage system 300 includes a mixing and stirring chamber 301, a variable speed stirring component 304 arranged in the mixing and stirring chamber 301, and a storage tank 302 connected to the mixing and stirring chamber 301.

[0039] The shell outlet of the partitioning heat exchanger 102 is connected to the air intake of the compressor through a circulation pipeline 201 , and the exhaust port of the compressor is connected to the inlet of the condensing heat exchanger 101 through a circulation pipeline 201 .

[0040] Furthermore, a connecting pipe 303 is provided between the mixing chamber 301 and the storage tank 302, and the circulating pump body 202 is arranged on the connecting pipe 303. The circulating pump body 202 is used to transport the emulsion from the storage tank 302 to the slurry ice machine 103 for ice making. The made ice is then discharged into the emulsion storage tank 302 through the circulating pump body 202 for circulation preparation.

[0041] Furthermore, in the present embodiment, the variable speed stirring component 304 includes a stirring rod 304a arranged in the mixing and stirring chamber 301, a stirring blade 304b arranged at the lower end of the stirring rod 304a, and a speed regulating component arranged on the stirring rod 304a, the speed regulating component is used to change the rotation speed of the stirring blade 304b, the stirring rod 304a is rotatably connected to the upper end of the mixing and stirring chamber, and a feed port and a discharge port are provided on the mixing and stirring chamber, and the height of the discharge port is lower than the height of the feed port.

[0042] Furthermore, a timing member 305 is provided on the speed regulating component, and a stepping motor 306 is provided on the upper end of the stirring rod 304 a , and the stepping motor 306 and the timing member 305 are electrically connected.

[0043] Preferably, a peristaltic pump is provided between the slurry ice machine 103 and the connecting pipe 303 .

[0044] Furthermore, in the present embodiment, the speed matching component 400 includes a driving motor 401 arranged on the stirring rod 304a, a covering cylinder 402 is fixed on the motor shaft of the driving motor 401, a connecting cylinder 402a is arranged at the end of the covering cylinder 402 away from the driving motor 401, the covering cylinder 402 and the connecting cylinder 402a are fixedly connected, and a driving pump wheel 403 is arranged in the connecting cylinder 402a, the driving pump wheel 403 includes a pump wheel housing fixedly connected to the connecting cylinder 402a, and then the rotation of the connecting cylinder 402a will synchronously drive the rotation of the pump wheel housing, and a plurality of paddles arranged in a circular array are arranged in the pump wheel housing.

[0045] Furthermore, a turbine 404 is arranged in the covering cylinder 402. The structure of the turbine 404 is the same as that of the driving pump wheel 403, except that the blades of the turbine 404 themselves are deflected at a certain angle, and the outer shell of the turbine 404 is not connected to the covering cylinder 402, so that the turbine 404 can rotate in the covering cylinder 402, and the turbine 404 and the driving pump wheel 403 are arranged opposite to each other, and the size of the turbine 404 and the driving pump wheel 403 are consistent. A bearing is arranged at the center of the turbine 404, and the bearing is sleeved on the driving motor 401, so that the rotation of the driving motor 401 will not drive the rotation of the turbine 404, and the entire connecting cylinder 402a and the covering cylinder 402 are filled with driving oil, and an output shaft connected to the stirring blade 304b of the drone is arranged at the center of the turbine 404.

[0046] An intermediate wheel 405 is connected to the output shaft through a bearing, and a toggle tooth 405a is provided on the inner wall of the intermediate wheel 405. A one-way ring tooth 405b is fixed to the outer side of the bearing. The one-way ring tooth 405b includes a first inclined surface and a second inclined surface. The angle between the first inclined surface and the tangent direction of the outer wall of the bearing is greater than the angle between the second inclined surface and the tangent direction of the outer wall of the bearing. The toggle tooth 405a is meshed with the one-way ring tooth 405b, so that the intermediate wheel 405 can only rotate in one direction.

[0047] A plurality of deflection blades 406 are arranged in an array on the outer wall of the intermediate wheel 405. The deflection blades 406 include a straight blade portion and an inclined blade portion. When observed from the positive direction of the deflection blade 406, the inclined blade portion is connected to the straight blade portion through a smooth arc surface. In the present embodiment, the inclined blade portions are all facing the same direction.

[0048] Preferably, the tilting direction of the tilted blades is opposite to the tilting direction of the blades of the turbine 404 .

[0049] An intermediate retaining ring 500 is arranged outside the intermediate wheel 405 , and side retaining rings 501 are arranged on the turbine 404 and the driving pump wheel 403 . The two side retaining rings 501 abut against the side walls of the intermediate retaining ring 500 .

[0050] The rest of the structure is the same as that of Example 1.

[0051] Operation process: When the driving motor 401 drives the connecting tube 402a to rotate, the connecting tube 402a will synchronously drive the driving pump wheel 403 to rotate. The rotation of the driving pump wheel 403 will hit the driving oil onto the turbine 404. When the driving pump wheel 403 rotates, the oil will spread outward due to centrifugal force, and then hit the turbine 404 from near the edge. Because the rotation of the driving pump wheel 403 increases the vortex for the oil leaving the driving pump wheel 403, the oil leaving the turbine 404 flows to the driving pump wheel 403 from the center of the turbine 404 (refer to Figure 7 direction of the arrow).

[0052] As the driving pump wheel 403 rotates faster and faster, the flow rate of the driving oil increases, which in turn causes the rotation speed of the turbine 404 to gradually increase. The rotation direction of the turbine 404 is consistent with the rotation direction of the driving pump wheel 403. When the turbine 404 rotates initially, the rotation speed is very low, causing the driving oil to hit the driving pump wheel 403 in a straight line. At this time, the oil speeds of the connecting cylinder 402a and the covering cylinder 402 close to the cylinder wall are high, while the oil speed in the center is low. The rotation of the worm wheel 404 also causes the oil to spread outward. Because the rotation speed of the worm wheel 404 is low at the beginning, the oil leaving the worm wheel 404 flows almost in a straight line. When the oil moves When it reaches the intermediate wheel 405, it will push the intermediate wheel 405 to rotate in the direction opposite to the rotation direction of the worm gear 404, and because of the one-way ring gear 405b set in the intermediate wheel 405, the intermediate wheel will not rotate. At this time, the oil will be deflected along the blades of the intermediate wheel 405, and the oil will hit the blades of the driving pump wheel 403 again, further increasing the rotation speed of the driving pump wheel 403 and generating greater torque, and making the oil that the driving pump wheel 403 hits the turbine 404 have greater force, thereby continuously increasing the rotation speed and torque of the turbine 404, and then the above process will be continuously repeated, and the rotation speed of the stirring blade 304b can be adjusted.

[0053] Furthermore, the above structure can adjust the rotation speed of the stirring blade 304b. The higher the speed of the input end, the higher the speed of the output end, and the output end speed can be adjusted more conveniently. If the speed needs to be reduced, it is only necessary to reduce the speed of the input end. At this time, the speed reduction will not be too fast, thereby ensuring that the speed reduction is in a slowing state, thereby ensuring stability during stirring.
