Description

Technical Field

[0001] This application relates to the field of mechanical design, and in particular to a liquor grain metering vehicle. Background Technology

[0002] Traditional grain-moistening processes rely heavily on manual extraction and sprinkling of boiling water at temperatures above 95°C. This method has several inherent drawbacks: operators must repeatedly perform strenuous physical labor, and are highly susceptible to burns in the hot, slippery environment, posing significant safety risks. Furthermore, the manual extraction and sprinkling process makes it impossible to precisely control the water volume and temperature, resulting in significant measurement discrepancies between each bucket of water. This leads to poor uniformity in grain moistening, with some grains failing to absorb enough water or becoming over-gelatinized, severely impacting subsequent gelatinization and fermentation, ultimately resulting in unstable wine quality.

[0003] The root of the problem lies in the obvious limitations of manual operation in high-temperature and high-precision scenarios. It is difficult to ensure process consistency and to achieve standardization and data-driven production processes, thus becoming a key bottleneck restricting production safety and quality improvement. Utility Model Content

[0024] The present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the scope of the present application.

[0025] This utility model relates to a liquor grain measuring vehicle, including a vehicle body, on which are provided:

[0026] Water pumps are used to provide the power for spraying;

[0027] The human-machine interface is electrically connected to the water pump and is used to receive set parameters and control the water pump's water volume and spraying speed for moistening the grain; it is equipped with a switch button to control the power supply to the water pump.

[0028] The detection unit is installed on the outlet pipe of the water pump to detect the flow rate, temperature and pressure of the water in real time, and is electrically connected to the human-machine interface.

[0029] The water spraying operation unit includes a hose reel and an extension hose wound on it, with the inlet end of the extension hose connected to the outlet of a pipe connected to a water pump.

[0030] The human-machine interface is configured to compare the real-time data fed back by the detection unit with the set value, and shut off the water pump when the set water volume is reached.

[0031] For example, the amount of water sprayed and the water output speed for this grain moistening can be set on the human-machine interface.

[0032] Through the cooperation of the water pump, human-machine interface and detection unit of this utility model, the set parameters can be received and the water pump’s water volume, water speed and water temperature can be controlled, ensuring the consistency of the process, effectively reducing the metering deviation between each barrel of water, and ensuring the uniformity of grain moistening and the stability of the wine quality.

[0033] As one embodiment of this application, the vehicle body is also equipped with a drainage pipe, the inlet of which is connected to the outlet pipe of the water pump for draining water from the pipes. Explained, after the water pump system stops operating, some water will remain in the outlet pipe, the pump chamber, or connected pipes. If this water remains for a long time, it may cause a series of problems: for example, in low-temperature environments, the water may freeze, causing the pipes or pump components to crack due to volume expansion; during non-use periods, the water may accelerate corrosion of the inner walls of the pipes or the metal parts of the pump, affecting equipment lifespan; if stagnant water exists in the pipes before the next startup, it may mix with new media, affecting the delivery quality. Alternatively, when the water temperature is too low, drainage can be initiated to reduce the content of low-temperature water inside the pipes, and high-temperature water can be added to raise the overall temperature of the pipes.

[0034] As one embodiment of this application, an indicator light, connected to the detection unit, is also included to provide feedback on the flow rate, temperature, and pressure in the pipeline. An audible alarm, connected to the detection unit, is also included to provide feedback on the flow rate, temperature, and pressure in the pipeline.

[0035] For example, the system automatically detects the water temperature during grain moistening spraying. If the water temperature is too low (below 95℃), an audible alarm will sound, "Water temperature is low, please drain water or turn on auxiliary heating," and the indicator light will flash yellow. After hearing the voice prompt, the system begins draining warm water, and the indicator light will flash yellow. When the required temperature (95℃) is reached, the audible alarm will sound, "Water temperature reached," and the indicator light will flash green. After hearing the voice prompt, align the water outlet with the grain pile to be moistened, press the water pump start button, and the audible alarm will sound, "Attention, water spraying begins." After a 3-second delay, water spraying will begin to moisten the grain, and the indicator light will flash green. When half the set weight of water has been sprayed, the audible alarm will beep, followed by a voice prompt, "Attention, half the water has been sprayed." When 90% of the set weight has been sprayed, the audible alarm will beep, followed by a voice prompt indicating the remaining water volume. When the set water volume is about to be reached, the audible alarm will sound, "Attention, water spraying is about to end, please note that the water will be turned off soon." When the water spray reaches the set water volume, the audible alarm will emit a long "beep" sound, stop spraying water, and the indicator light will flash yellow.

[0036] If the water temperature is too low (below 95℃), the audible alarm will announce, "Please note, water temperature is low, please heat or drain the warm water," and the yellow indicator light will flash. The draining process needs to be repeated. If the pressure is too high, the audible alarm will announce, "Please note, water pressure is high, please check for blockages in the pipes," and the red indicator light will flash. The red indicator light will turn off after the fault is cleared.

[0037] As one embodiment of this application, a backflow check valve is installed at the outlet of the pipeline to prevent residual water at the high level or end of the pipeline from flowing back to the pump or even emptying due to gravity or siphon effect when the pump stops. Explained, when the pump stops running, residual water in the high-level area or end of the pipeline will tend to flow downwards due to gravity. Simultaneously, if a negative pressure condition exists in the pipeline system, a siphon effect may also occur, causing water to flow back. This backflow not only causes the pump's internal components to be impacted by the reverse flow of water, potentially damaging components such as the impeller and shaft seal, but it may also cause the water in the pipeline to empty, requiring re-airing and refilling when restarting the pump, increasing operational inconvenience, and even causing dry running damage to the pump.

[0038] The backflow check valve, through the unidirectional conduction characteristic of its internal valve core, allows water to flow only in the direction of the pump's outlet. When reverse flow occurs, the valve core automatically closes the valve port under water pressure, blocking the backflow path. This design effectively prevents residual water from flowing back to the pump, protecting the pump from reverse impact, while maintaining the water level in the pipeline. This ensures that the pump can quickly return to normal operation upon restarting, reducing equipment damage and operating costs caused by backflow during pump shutdown.

[0039] As one embodiment of this application, the water pump's inlet end is connected to a pipe to form an inlet, and an inlet filter is installed at the inlet to filter out impurities in the hot water entering the pump. Explanatoryly, hot water may contain impurities such as scale, rust, and sediment. If these impurities enter the pump, long-term operation may lead to problems such as impeller wear, bearing jamming, and seal damage, which will not only reduce pump efficiency but also shorten its service life and may even cause malfunctions and shutdowns.

[0040] The inlet filter, through its structure such as a filter screen, can effectively intercept impurities in the water and prevent them from entering the pump cavity. This protects the pump's key components (such as impellers, bushings, and mechanical seals) from wear and blockage, maintains the pump's stable operation, reduces maintenance frequency and costs, and extends the overall service life of the equipment.

[0041] In practical applications, it is necessary to select a filter with appropriate filtration precision and diameter based on the particle size and content of impurities in the hot water and the flow parameters of the water pump. The filter should be cleaned or the filter screen replaced regularly to ensure that its filtration effect is always reliable and to avoid increased water inlet resistance due to filter blockage, which would affect the water pump's water suction performance.

[0042] As one embodiment of this application, it also includes movable wheels, which are disposed at the bottom of the vehicle body for moving the vehicle. Explanatoryly, in terms of design, the selection of movable wheels needs to consider factors such as vehicle weight and usage environment: if the vehicle body has a large load, solid rubber wheels or metal wheels with strong load-bearing capacity are usually selected to avoid wheel deformation; if used on smooth ground (such as indoor tiles), rubber wheels with anti-slip texture can be selected to reduce slippage; if it needs to move on rough outdoor ground, the wear resistance and shock absorption of the wheel body need to be considered, and in some scenarios, movable wheels with braking function are configured to fix the position when the vehicle body is parked and prevent accidental slippage.

[0043] The installation positions of the casters also need to be arranged reasonably, usually symmetrically distributed on both sides of the bottom of the vehicle body to ensure that the vehicle body is evenly stressed and to avoid tilting or jamming during movement, thereby further ensuring the stability and safety of the movement process.

[0044] As one embodiment of this application, insulation material is wrapped around the outer surface of the pipe to reduce the temperature difference between the inlet and outlet of the hot water flowing through the pipe. Explaining this, from the perspective of heat transfer principles, when hot water flows through a pipe, it exchanges heat with the external environment through the pipe wall. When the temperature of the hot water inside the pipe is higher than the ambient temperature, heat is lost to the outside through conduction, convection, and radiation, causing the water temperature to gradually decrease with the distance of transport, ultimately resulting in a significant temperature difference between the inlet and outlet. This temperature difference not only affects the usability of the hot water but also increases energy consumption due to heat waste.

[0045] Insulation materials such as rock wool, glass wool, polyurethane foam, and rubber-plastic sponge are selected to form a thermal barrier outside the pipes, significantly reducing heat transfer efficiency, thanks to their low thermal conductivity. The porous structure within the materials, combined with the gaps between their fibers, effectively blocks air convection, reduces heat conduction paths, slows down the cooling rate of the hot water, and minimizes the temperature difference between the inlet and outlet, achieving the dual goals of energy saving and stable water temperature.

[0046] In one embodiment of this application, the water flow path begins at an external water source and connects to the water pump inlet via a quick-connect chuck straight pipe, using a threaded connection. After being pressurized by the water pump, hot water is discharged from the outlet through another quick-connect chuck straight pipe. This straight pipe is connected to a tee vertical port via a snap-fit ​​connection with a sealing gasket; the other vertical port of the tee is also connected via a snap-fit ​​connection to a section of internally threaded chuck straight pipe, and an externally threaded vent valve 5 is screwed in.

[0047] On the other tee's horizontal port, a temperature and pressure sensor mounting base is installed using a snap-fit ​​method, on which a temperature transmitter 6 and a pressure transmitter 10 are respectively mounted. One vertical port of the tee is connected to the inlet of a flow meter 13 via a snap-fit ​​connection, and the outlet of the flow meter 13 is connected to a double-clamp straight pipe via a snap-fit ​​connection, with the other end of the pipe extending as the outlet 12 of the pipeline.

[0048] A hose reel 11 is provided at the rear of the metering vehicle in this application. A ten-meter-long TPU food-grade extension hose is fixed on it with a U-shaped clip. A quick-connect chuck is fixed at each end of the hose by a clamp. One end of the chuck is connected to the outlet 12 of the hose, and the other end is connected to an external handheld water spray hose assembly.
