[0030] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0032] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0033] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0034] An embodiment of the utility model provides a material return device of a mixer. By way of example, this embodiment uses the filling production process of a carbonated beverage to illustrate the material return device of the mixer.

[0035] like Figure 1As shown, the mixer includes a carbonization tank 100 and a heat exchanger 200. The feed port of the carbonization tank 100 is provided with a feed pipe 101, and the heat exchanger 200 is arranged on the feed pipe 101; the discharge port of the carbonization tank 100 is provided with a discharge pipe 102, and the discharge pipe 102 is connected to the filling cylinder 300 through a feeding pipe 301; the end of the feed pipe 101 away from the carbonization tank 100 is used to connect the final syrup and deoxygenated water, so that the final syrup and deoxygenated water can enter the feed pipe 101 in proportion, and after being cooled at the heat exchanger 200, they are further mixed with carbon dioxide in the feed pipe 101 and then enter the carbonization tank 100. Conventionally, the product passing through the heat exchanger 200 has a compliant temperature range and is stored in the carbonization tank 100 for filling. However, in the actual production process, due to malfunctions in the front and rear end equipment of the mixer, the mixed product is stored in the carbonization tank 100 for a long time, which will cause the temperature of the product at the discharge port of the carbonization tank 100 to exceed the standard, which will in turn cause the temperature of the product in the filling cylinder 300 to exceed the standard, affecting the quality of the filled product.

[0036] In order to solve the above technical problems, the present embodiment provides a return device of a mixer, including a return pipe 1, the first end 11 of the return pipe 1 is connected to the feed pipe 101 and can be selectively connected to the feed pipe 101, and the heat exchanger 200 is located between the first end 11 and the feed port of the carbonization tank 100; the second end 12 of the return pipe 1 is connected to the discharge pipe 102 and can be selectively connected to the discharge pipe 102 or the loading pipe 301; when the feed pipe 101, the discharge pipe 102 and the return pipe 1 are connected in sequence, the return device of the mixer is in a self-circulating cooling mode; when the loading pipe 301, the return pipe 1 and the feed pipe 101 are connected in sequence, the return device of the mixer is in a return mode.

[0037] The material return device of the mixer provided by the utility model has a self-circulating cooling mode and a material return mode by setting a material return pipe 1. When an over-temperature situation occurs in the normal feeding process of the mixer, the material return device of the mixer can be started. In the self-circulation cooling mode, the product in the carbonization tank 100 passes through the discharge pipe 102, the return pipe 1 and the feed pipe 101 in sequence and then returns to the carbonization tank 100. Combined with the heat exchanger 200 on the feed pipe 101, the product in the carbonization tank 100 can be circulated and cooled to ensure that the product in the carbonization tank 100 is within a normal temperature range; in the return mode, the feed pipe 301, the return pipe 1 and the feed pipe 101 are connected, and the product in the filling cylinder 300 can be returned to the carbonization tank 100, and then cooled by the self-circulation mode of the carbonization tank 100, so as to achieve the cooling of the product in the filling cylinder 300 again to meet the temperature requirements; the utility model effectively avoids the problem of affecting the filling quality due to the increase in the temperature of the filled product, which is beneficial to saving production costs and improving filling efficiency.

[0038] In some embodiments, the return pipe 1 is provided with a first valve 13, the discharge pipe 102 is provided with a second valve 103, and the loading pipe 301 is provided with a third valve 302. When the first valve 13 and the second valve 103 are connected and the third valve 302 is closed, the carbonization tank 100 is cooled by self-circulation; when the first valve 13 and the third valve 302 are connected and the second valve 103 is closed, the filling cylinder 300 returns the material.

[0039] like Figure 2 As shown, during normal feeding, the final syrup and deoxygenated water enter the feed pipe 101 in proportion, and after cooling, they are mixed with carbon dioxide and enter the carbonization tank 100. The product in the carbonization tank 100 passes through the discharge port of the carbonization tank 100, and successively passes through the discharge pipe 102 and the feeding pipe 301 to enter the filling cylinder 300. The filling cylinder 300 is used for product filling, thereby realizing the normal online feeding, feeding and filling process. Among them, the heat exchanger 200 of the mixer is always connected with a cooling medium to cool and heat the product in the feed pipe 101, and a three-way proportional valve 203 is provided between the inlet pipe 201 and the return pipe 202 of the cooling medium to connect and control the cooling temperature of the product. During normal feeding, the second valve 103 and the third valve 302 are open and conductive, the fourth valve 401 and the fifth valve 501 on the final syrup pipeline 400 and the deoxygenated water pipeline 500 are both open for feeding, and the sixth valve 601 on the carbon dioxide pipeline 600 is open for gas supply. At the same time, the carbonization tank 100 is designed with a heat preservation function to delay the increase in product temperature. When an abnormality occurs and causes the product temperature in the carbonization tank 100 to be higher than the set value range, the mixer cycle cooling process is executed.

[0040] In the self-circulating cooling mode, the fourth valve 401, the fifth valve 501 and the sixth valve 601 are all closed to stop feeding; the first valve 13 and the second valve 103 are opened, and the third valve 302 is closed to stop feeding; at this time, the product in the carbonization tank 100 passes through the discharge pipe 102, the return pipe 1 and the feed pipe 101 in sequence, and returns to the carbonization tank 100 after being further cooled in the feed pipe 101, until the product temperature in the carbonization tank 100 meets the requirements.

[0041] In the return mode, the fourth valve 401, the fifth valve 501 and the sixth valve 601 are all closed to stop feeding; the first valve 13 and the third valve 302 are opened, and the second valve 103 is closed to stop discharging; at this time, the product in the filling cylinder 300 passes through the loading pipe 301, the return pipe 1 and the feed pipe 101 in sequence, and returns to the carbonization tank 100 after being further cooled in the feed pipe 101; when all the products in the filling cylinder 300 are returned to the carbonization tank 100, the self-circulation cooling mode is executed on the carbonization tank 100 until the product temperature meets the requirements.

[0042] In some embodiments, two first valves 13 are provided, and the two first valves 13 are respectively disposed on the return pipe 1 close to the first end 11 and the second end 12 .

[0043] like Figure 1 As shown, it can be understood that a first valve 13 is provided at each end of the return pipe 1 to prevent product from being retained in the return pipe 1. Moreover, the two first valves 13 can realize dual conduction control of the return pipe 1 to prevent the return pipe 1 from accidentally conducting and affecting production.

[0044] In some embodiments, the first valve 13, the second valve 103 and the third valve 302 are all pneumatic valves, and the pneumatic valves are communicatively connected with the controller.

[0045] Furthermore, the fourth valve 401, the fifth valve 501 and the sixth valve 601 are also pneumatic valves, such as pneumatic butterfly valves or pneumatic seat valves, so that the status of each pneumatic valve can be collected and monitored through a controller, which is conducive to automatic control and improves production efficiency.

[0046] In some embodiments, the carbonization tank 100 is provided with a first temperature detection device 104, and the filling cylinder 300 is provided with a second temperature detection device 303, and both the first temperature detection device 104 and the second temperature detection device 303 are communicatively connected to the controller.

[0047] like Figure 1 The controller is used to collect the temperatures of the first temperature detection device 104 and the second temperature detection device 303 in real time. When either of the two exceeds the specified temperature range, the controller controls the corresponding pneumatic valve to operate and sends an over-temperature signal, and the carbonization tank 100 or the filling cylinder 300 starts the self-circulation cooling mode and / or the return material mode until the temperature detected by the controller returns to the normal value again.

[0048] In some embodiments, the carbonization tank 100 is provided with a first pressure detection device 105, and the filling cylinder 300 is provided with a second pressure detection device 304, and both the first pressure detection device 105 and the second pressure detection device 304 are communicatively connected to the controller.

[0049] It can be understood that by collecting the detection values ​​of the first pressure detection device 105 and the second pressure detection device 304 in real time through the controller, the pressure in the carbonization tank 100 and the filling cylinder 300 can be detected in real time. It should be noted that in the return mode, the controller (PLC control unit) first reduces the pressure of the carbonization tank 100 to make it lower than the pressure of the filling cylinder 300 (or increases the pressure of the filling cylinder 300 to be higher than the pressure of the carbonization tank 100), and then opens the corresponding pneumatic valve, which can return the over-temperature product in the filling cylinder 300 to the carbonization tank 100 through the return pipe 1, and cool it down in the heat exchanger 200 of the mixer when passing through the feed pipe 101, and keep it warm in the carbonization tank 100.

[0050] In some embodiments, the carbonization tank 100 is provided with a first liquid level detection device 106 , and the filling cylinder 300 is provided with a second liquid level detection device 305 . Both the first liquid level detection device 106 and the second liquid level detection device 305 are communicatively connected to the controller.

[0051] For example Figure 1 , the controller collects the measured values ​​of the first liquid level detection device 106 and the second liquid level detection device 305 in real time to monitor the liquid levels in the carbonizing tank 100 and the filling cylinder 300 in real time. When the liquid levels in the carbonizing tank 100 and the filling cylinder 300 reach the set value, the controller can automatically close the corresponding pneumatic valves so that the product is circulated and cooled in the mixer (same as the self-circulating cooling mode). In order to return all the products with too high temperature in the filling cylinder 300 to the carbonizing tank 100 for self-circulating cooling, the capacity of the carbonizing tank 100 needs to be reasonably designed, and the liquid levels of the carbonizing tank 100 and the filling cylinder 300 need to be reasonably controlled during the production process. In some embodiments, the volume of the carbonizing tank 100 is greater than the volume of the filling cylinder 300, and the residual product capacity of the feed pipe 101, the discharge pipe 102 and the return pipe 1 needs to be considered.

[0052] In some embodiments, a first pump 1011 is provided on the feed pipe 101, and the first pump 1011 is used to pump the product in the feed pipe 101 into the carbonization tank 100. A second pump 1021 is provided on the discharge pipe 102, and the second pump 1021 is used to pump out the product in the carbonization tank 100.

[0053] like Figure 1 As shown, two first pumps 1011 are usually provided, which are respectively located at both ends of the heat exchanger 200, and are used to pump both the final syrup and the deoxygenated water into the feed pipe 101, while ensuring that the product in the feed pipe 101 has sufficient power to pump the product into the carbonization tank 100. The discharge pipe 102 is provided with a second pump 1021, which is used to pump out the product in the carbonization tank 100, so as to facilitate the feeding to the filling cylinder 300 or the power for circulating cooling. Among them, the first pump 1011 and the second pump 1021 are both connected to the controller for communication to achieve automatic control.

[0054] The material return device of the mixer provided in the embodiment of the utility model returns the material to cool down when the product temperature in the carbonization tank 100 and / or the filling cylinder 300 of the mixer exceeds the set value, thereby solving the problem of having to discharge the material due to the excessively high product temperature.

[0055] It is additionally noted that if Figure 1 The feed pipe 101 is also provided with a first flow detection device 1012 and a third temperature detection device 1013 for real-time monitoring of the flow and temperature of the product in the feed pipe 101. The first flow detection device 1012 and the third temperature detection device 1013 are both communicatively connected to the controller. In some embodiments, a one-way valve 1022 is provided at the outlet of the second pump 1021 on the discharge pipe 102 to prevent backflow in the discharge pipe 102. A second flow detection device 602 is provided on the carbon dioxide pipeline 600 to monitor the supply amount of carbon dioxide.

[0056] The embodiment of the utility model further provides a mixing machine, including a material return device of the mixing machine provided by the utility model.

[0057] like Figure 1 As shown, the mixer includes a carbonization tank 100 and a heat exchanger 200 arranged on a feed pipe 101 of the carbonization tank 100. In this embodiment, a return pipe 1 is connected between the discharge pipe 102 of the carbonization tank 100 and the feed pipe 101 to form a circulation pipeline, and the heat exchanger 200 is located in the circulation pipeline, so that the over-temperature product in the carbonization tank 100 can be self-circulated for cooling; the discharge pipe 102 and the feed pipe 301 are selectively connected through the return pipe 1 to realize the return of the product in the filling cylinder 300. When the product in the filling cylinder 300 is over-temperature, the return and cooling can also be achieved, which solves the problem of having to discharge the product due to excessively high product temperature.

[0058] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
