DETAILED DESCRIPTION

[0013] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0014] Please refer to Figure 1 The present invention provides a feeding device for a carbonated snow melter, comprising a storage mechanism, a mixing mechanism and a discharging mechanism.

[0015] Please refer to Figure 1 The storage mechanism includes a gas tank 11, a water tank 12 and a left syrup tank 13. The gas tank 11 has a closed gas storage cavity, in which compressed carbon dioxide gas is contained. The water tank 12 has a closed water storage cavity, and the left syrup tank 13 has a closed left syrup cavity.

[0016] Please refer to Figure 1 The mixing mechanism includes a first pneumatic pump 21, a second pneumatic pump 22 and a left mixing valve 23. The air inlet of the first pneumatic pump 21 is connected to the air storage chamber, and the compressed gas in the air storage chamber provides a power source for the first pneumatic pump 21. The inlet of the first pneumatic pump 21 is connected to the water storage chamber, and the air inlet of the second pneumatic pump 22 is connected to the air storage chamber. The compressed gas in the air storage chamber provides a power source for the second pneumatic pump 22. The inlet of the second pneumatic pump 22 is connected to the left syrup chamber. The left mixing valve 23 has a closed left mixing chamber, and the left mixing chamber is connected to both the outlet of the first pneumatic pump 21 and the outlet of the second pneumatic pump 22.

[0017] Please refer to Figure 1The discharging mechanism includes a left constant pressure tank 31 and a left refrigeration cylinder 32. The left constant pressure tank 31 has a sealed left constant pressure chamber 311. The left constant pressure chamber 311 is connected to the left mixing chamber and the air storage chamber. The left refrigeration cylinder 32 has a sealed left refrigeration chamber. The left refrigeration chamber is connected to the left constant pressure chamber 311. The left refrigeration cylinder 32 is provided with a left discharge port 321 connected to the left refrigeration chamber. A left pressure sensor 33 is provided on the channel connecting the left refrigeration chamber and the left constant pressure chamber 311.

[0018] When the feeding device of the carbonated snow melter provided by the present invention is in use, the gas cylinder 11 is opened, and the compressed carbon dioxide gas in the gas cylinder 11 enters the air inlet of the first pneumatic pump 21 and the air inlet of the second pneumatic pump 22, thereby driving the first pneumatic pump 21 and the second pneumatic pump 22 to operate, the first pneumatic pump 21 pumps the water in the water tank 12 into the left mixing valve 23, and the second pneumatic pump 22 pumps the syrup in the left syrup tank 13 into the left mixing valve 23, and the ratio of water and syrup is adjusted by the left mixing valve 23, and the water and syrup are preliminarily mixed; then the water-slurry mixture is pressed into the left constant pressure tank 31, and at the same time, the carbon dioxide in the gas cylinder 11 is also pressed into the left constant pressure chamber 311 in the left constant pressure tank 31 and mixed with the water-slurry mixture, and the pressure in the left constant pressure chamber 311 is maintained at 30PSI. Under the action of this pressure, the gas-water slurry mixture is pressed into the left refrigeration cylinder 32, and forms ice after low temperature and stirring in the left refrigeration cylinder 32 Sand, with the continuous increase of the gas-water slurry mixture, the left constant pressure chamber 311 is gradually saturated, causing the system pressure to exceed 30PSI. When the pressure detected by the left pressure sensor 33 exceeds 30PSI, the left mixing valve 23 is closed and the communication channel between the left constant pressure chamber 311 and the gas storage chamber is cut off; when it is necessary to take materials, the left discharge port 321 is opened, and the ice cream is squeezed out under the action of the pressure in the left refrigeration cylinder 32. The pressure in the left refrigeration cylinder 32 and the left constant pressure chamber 311 is reduced, and the gas-water slurry mixture in the left constant pressure chamber 311 is continuously squeezed out to keep the system pressure at 30PSI. When the gas-water slurry mixture in the left constant pressure chamber 311 is completely squeezed out, the system pressure will be less than 30PSI. When the pressure detected by the left pressure sensor 33 is less than 30PSI, the left mixing valve 23 is opened and the communication channel between the left constant pressure chamber 311 and the gas storage chamber is restored, thereby replenishing the gas-water slurry mixture into the left constant pressure chamber 311, and repeating the above steps.

[0019] For details, please refer to Figure 1 and Figure 2The left constant pressure tank 31 has a sealed accommodating chamber, in which a pressure regulating capsule 312 is arranged, and the pressure regulating capsule 312 divides the accommodating chamber into a pressure chamber 313 and the left constant pressure chamber 311; the discharging mechanism also includes a first pressure regulating valve 34, one end of which is connected to the gas storage chamber, and the other end of which is connected to the pressure chamber 313. In this embodiment, the outlet pressure of the first pressure regulating valve 34 is set to 30PSI, so that the pressure in the pressure chamber 313 is maintained at 30PSI. When the pressure in the left constant pressure chamber 311 is greater than 30PSI, the pressure regulating capsule 312 moves toward the pressure chamber 313, so that the pressure in the left constant pressure chamber 311 is maintained at 30PSI.

[0020] Preferably, please refer to Figure 1 The mixing mechanism further includes a second pressure regulating valve 24, a third pressure regulating valve 25 and a fourth pressure regulating valve 26.

The right constant pressure tank 35 has a sealed right constant pressure chamber, which is connected to the right mixing chamber and the air storage chamber. The right refrigeration cylinder 36 has a sealed right refrigeration chamber, which is connected to the right constant pressure chamber. The right refrigeration cylinder 36 is provided with a right discharge port 361 connected to the right refrigeration chamber, and a right pressure sensor 37 is provided on the channel connecting the right refrigeration chamber and the right constant pressure chamber.

[0022] Preferably, please refer to Figure 1One end of the third pressure regulating valve 25 is connected to the air inlet of the second pneumatic pump 22 and the air inlet of the third pneumatic pump 27, and the other end of the third pressure regulating valve 25 is connected to the air storage chamber; one end of the fourth pressure regulating valve 26 is connected to the air storage chamber, and the other end of the fourth pressure regulating valve 26 is connected to the left constant pressure chamber 311 and the right constant pressure chamber.

It should be pointed out that the controller in this embodiment can be easily implemented by simple programming of a common PLC on the market, and simple programming by PLC is a prior art, and the present invention does not protect the programming implementation method; of course, in actual use, the carbonic acid snow melter feeding device provided in this embodiment may not be provided with a controller, and the opening and closing of the left mixing valve 23, the right mixing valve 28 and the gas valve 29 may be directly controlled manually, and the present invention does not limit this.

[0025] In order to better understand the present invention, the following Figure 1 and Figure 2The working process of the feeding device of the carbonated snow melter provided by the present invention is described in detail: when in use, the gas tank 11 is opened, and the compressed carbon dioxide gas in the gas tank 11 enters the air inlet of the first pneumatic pump 21 and the air inlet of the second pneumatic pump 22, thereby driving the first pneumatic pump 21 and the second pneumatic pump 22 to operate, and the first pneumatic pump 21 pumps the water in the water tank 12 into the left mixing valve 23, and the second pneumatic pump 22 pumps the syrup in the left syrup tank 13 into the left mixing valve 23, and the ratio of water and syrup is adjusted by the left mixing valve 23, and the water and syrup are preliminarily mixed; then the water-slurry mixture is pressed into the left constant pressure tank 31, and at the same time, the carbon dioxide in the gas tank 11 is also pressed into the left constant pressure chamber 311 in the left constant pressure tank 31 and mixed with the water-slurry mixture, and the pressure in the left constant pressure chamber 311 is maintained at 30PSI. Under the action of this pressure, the gas-water slurry mixture is pressed into the left refrigeration cylinder 32, and passes through the low temperature in the left refrigeration cylinder 32 After stirring, smoothies are formed. As the gas-water slurry mixture increases, the left constant pressure chamber 311 is gradually saturated, causing the system pressure to exceed 30PSI. When the pressure detected by the left pressure sensor 33 exceeds 30PSI, the left mixing valve 23 and the air valve 29 are closed. When it is necessary to take materials, the left discharge port 321 is opened, and the smoothies are squeezed out under the action of the pressure in the left refrigeration cylinder 32. The pressure in the left refrigeration cylinder 32 and the left constant pressure chamber 311 is reduced, and the gas-water slurry mixture in the left constant pressure chamber 311 is continuously squeezed out to keep the system pressure at 30PSI. When all the gas-water slurry mixture in the left constant pressure chamber 311 is squeezed out, the system pressure will be less than 30PSI. When the pressure detected by the left pressure sensor 33 is less than 30PSI, the left mixing valve 23 and the air valve 29 are opened to replenish the gas-water slurry mixture in the left constant pressure chamber 311, and the above steps are repeated. The working process in the right constant pressure tank 35 and the right refrigeration cylinder 36 is similar and will not be described in detail.

[0026] In summary, the present invention controls the feeding process of the carbonated snow melt machine by replacing the traditional electric control method with the pneumatic control method, which greatly reduces the usage of the solenoid valve and reduces the production cost of the carbonated snow melt machine.
