For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the embodiments of the present invention will be described in further detail with reference to the accompanying drawings.
Example 1
As shown in fig. 5 and 7, the present embodiment provides a bubble eliminating device, which includes a main pump 31 and a main pipe, wherein an input end of the main pump 31 is connected with a beverage can through the main pipe, an output end of the main pump 31 is connected with a liquid discharge faucet 32 through the main pipe, the bubble eliminating device further includes a bypass pump 35 and an exhaust pipe, an input end of the bypass pump 35 is connected with the main pipe between the main pump 31 and the liquid discharge faucet 32 through the exhaust pipe, an output end of the bypass pump 35 is connected with a gas outlet through the exhaust pipe, and after the beverage can is replaced, gas in the main pump 31 and the main pipe between the main pump 31 and the beverage can is discharged through the bypass pump 35.
In order to prevent the backflow of liquid and gas from one end of the liquid discharge tap 32, a one-way check valve 33 is arranged on the main pipeline between the main pipeline pump 35 and the liquid discharge tap 32, and the input end of the bypass pump 35 is connected with the main pipeline between the main pipeline pump 31 and the one-way check valve 33 through an exhaust pipeline.
In order to prevent backflow of liquid and gas from the exhaust port, a one-way check valve 37 is also provided in the exhaust line between the bypass pump 35 and the exhaust port. Thus, the main pipeline and the exhaust pipeline are not mutually influenced when in use.
The beverage cartridge in the bubble removing means comprises at least one beverage cartridge which can deliver a beverage when the bubble removing means is applied in the beverage machine.
The beverage cartridges in the bubble removing means may comprise a plurality of beverage cartridges, and when the bubble removing means is applied to the beverage machine, a plurality of beverages may be outputted.
When a plurality of beverage barrels are included, after any beverage barrel is replaced, the bypass pump 35 can discharge the gas in the main pump 31 and the main pipeline between the main pump 31 and the beverage barrel.
In this embodiment, the gas outlet also uses a drain tap 32, and the output end of the bypass pump 35 is connected to the main line between the one-way check valve 33 and the drain tap 32 through a vent line, and the gas is discharged from the drain tap 32. After the beverage cartridge is replaced, bypass pump 35 is automatically activated to expel gas from drain tap 32 in preparation for vending the beverage. When the beverage is sold, the main pump 31 and the main pipeline between the main pump 31 and the beverage barrel are not provided with gas, so that the phenomena of air lock and pipeline impact are avoided, and foam is not generated.
When the bypass pump 35 is exhausted, gas, possibly foam and a small amount of liquid are discharged from the liquid discharge tap 32, and in order to remove the foam and the liquid, a proper flow guiding device is required to be arranged below the liquid discharge tap 32 to guide the foam and the liquid discharged during the exhaust.
The bubble eliminating device also comprises a control device 20 which is connected with the main pump 31 and the bypass pump 35 and controls the start and stop of the main pump 31 and the bypass pump 35. The control device 20 may employ a PLC.

In order to detect whether the bypass pump 35 discharges the gas in the main line, a liquid sensor is provided in association with the drain tap 32 to detect whether or not the liquid is outputted from the drain tap 32, and the liquid sensor sends a detection signal to the control device 20 to turn off the bypass pump 35 when the liquid is outputted from the drain tap 32.
The liquid sensor can detect and distinguish liquid and gas, and generate different detection signals.
Because the gas entering the main pipeline is limited, when the bypass pump 35 is started to exhaust, the gas entering the main pipeline can be quickly exhausted, liquid can follow the gas entering the exhaust pipeline and can be output from the liquid discharge tap 32, the liquid discharge tap 32 is detected through the liquid sensor, once the liquid is output, the control device 20 shuts off the bypass pump 35, and the waste of the beverage is prevented.
Typically, the inlet end of the main conduit is inserted into the beverage container near the bottom of the beverage container so that the beverage in the beverage container is drained as much as possible.
In order to realize the control of the exhaust flow, the liquid storage amount in the beverage barrel comprises three water level states of serious low water level, low water level and high water level.
The depth of the liquid storage space is equal to or smaller than the height of the input end of the main pipeline, the depth of the liquid storage space is equal to or smaller than half of the depth in the beverage barrel, and the depth of the liquid storage space is greater than half of the depth in the beverage barrel.
The low water level and the high water level are non-severe low water levels.
As shown in fig. 7, the air discharge flow of the bubble removal device includes the steps of:
s1: initializing equipment, and zeroing the water level state and the reading of the in-place sensor;
s2: reading the value of the current in-place sensor, and judging whether the water level state in the beverage barrel is a serious low water level, a non-serious low water level, a low water level or a high water level;
s3: if the current water level state is a serious low water level and the last water level state is a non-serious low water level, the main pump and the bypass pump are closed to prevent the beverage from being continuously output; whether the last water level state is the serious low water level or not, the current water level state is set as the serious low water level in the control device according to the current water level state;
s4: if the current water level state is a low water level and the last water level state is a non-serious low water level, the control device sets the bypass pump in a starting mode; whether the last water level state is a non-serious low water level or not, the current water level state is set as a low water level in the control device according to the current water level state;
s5: if the current water level state is a non-low water level and the last water level state is a non-serious low water level, the control device starts and sets the bypass pump; whether the last water level state is a non-serious low water level or not, the current water level state is set to be a high water level in the control device according to the current water level state;
s6: in the control device, if the current water level state is a serious low water level, starting an adding warning, and returning to the step S2;
s7: in the control device, if the current water level state is a non-serious low water level, judging whether a water outlet request exists at present; if not, returning to S2;
s8: if the water outlet request is retrieved, starting the main pump and judging whether the bypass pump is set; if not, returning to S2;
s9: if the bypass pump is set, bypass pump exhaust is turned on and bypass pump start set is eliminated, after which S2 is returned.
The bypass pump start setting is preset for starting the bypass pump 35, and when the bypass pump is not set in the start, the bypass pump 35 cannot be started, and after the bypass pump is set in the start, the bypass pump 35 can be started.
In this embodiment, the in-place sensor is a pressure sensor, and is disposed below the installation place of the beverage can. When the beverage barrel is not installed in place, the in-place sensor cannot detect pressure; after the beverage barrel is installed in place, the in-place sensor can detect pressure, and along with the change of the liquid storage capacity in the beverage barrel, the in-place sensor can detect different pressure values, so that whether the beverage barrel is installed in place or not and the liquid storage capacity in the beverage barrel can be detected.
Compared with the liquid level detector and the in-place detector in the prior art, the in-place sensor in the embodiment can play two roles at the same time, and the circuit structure is simplified.
Preferably, the main pump 31 adopts a centrifugal pump, the flow speed of the centrifugal pump is stable, the flow is stable, and the pumping quantity, namely the beverage quantity in the beverage cup can be controlled only by controlling the opening time of the centrifugal pump. Of course, a flowmeter may be provided to effect feedback control of the main pump 31, as desired, to effect more accurate control of the output. The bypass pump 35 adopts a diaphragm pump, and a high-wear-resistance food-grade silica gel membrane is adopted in the bypass pump, so that the safety and the sanitation of the beverage can be ensured.
The main pump 31 may be a diaphragm pump.
When the beverage barrel is taken out and reset again, the bubble eliminating device in the embodiment can discharge the gas entering the beverage output pipeline when the beverage barrel is replaced, so that the beverage output pipeline is kept full of liquid, the smooth liquid flow is ensured, the phenomenon of air lock and pipeline impact can not occur, and the foam generated during beverage output is effectively eliminated.
Example 2
As shown in fig. 6, embodiment 2 of the present invention is different from embodiment 1 in that: an exhaust tap 36 is provided in parallel with the drain tap 32, and the exhaust port uses the exhaust tap 36, and the output end of the bypass pump 35 in this embodiment is connected to the exhaust tap 36 through an exhaust pipe. After the beverage cartridge is replaced, bypass pump 35 is automatically activated to discharge gas from discharge tap 36 in preparation for vending the beverage. When the beverage is sold, the main pump 31 and the main pipeline between the main pump 31 and the beverage barrel are not provided with gas, so that the phenomena of air lock and pipeline impact are avoided, and foam is not generated.
In order to prevent the backflow of liquid and gas from the end of the exhaust tap 36, a one-way check valve 37 is also provided in the exhaust line between the bypass pump 35 and the exhaust tap 36. Thus, the main pipeline and the exhaust pipeline are not mutually influenced when in use.
Preferably, the exhaust tap 36 is connected to the waste reservoir by a pipe. Since the gas and foam discharged from the exhaust tap 36 are not valuable, there is no need to provide a recovery device. Even if the liquid is discharged from the discharge cock 36, the various beverages are easily mixed and difficult to distinguish, so that the recovery device is not required, and the liquid is directly discharged to the waste liquid tank.
In order to detect whether the bypass pump 35 discharges the gas in the main line, a liquid sensor is provided in association with the discharge tap 36 to detect whether or not the liquid is output from the discharge tap 36, and the liquid sensor sends a detection signal to the control device 20 to turn off the bypass pump 35 when the liquid is output from the discharge tap 36.
The liquid sensor can detect and distinguish liquid and gas, and generate different detection signals.
Because the gas entering the main pipeline is limited, when the bypass pump 35 is started to exhaust, the gas entering the main pipeline can be quickly exhausted, liquid can follow the gas entering the exhaust pipeline and can be output from the exhaust tap 36, at this time, the exhaust tap 36 is detected through the liquid sensor, once the liquid is output, the control device 20 shuts off the bypass pump 35, and the waste of the beverage is prevented.
