Description

Technical Field

[0001] This utility model belongs to the technical field of butter melting tanks, specifically relating to a rapid venting device for butter melting tanks. Background Technology

[0002] A butter melting tank is a specialized device used to convert solid butter into liquid butter. It is widely used in the food, cosmetics, and pharmaceutical industries. Currently, butter melting devices mainly consist of a stainless steel butter melting tank, a jacketed water tank, water circulation pipes, and several auxiliary devices. Butter melting involves placing the butter through the inlet onto the heating coil inside the butter melting tank. The heating coil is connected to the water circulation pipes. Utilizing the thermal conductivity of hot water, heat is transferred from the hot water to the butter, thereby achieving the effect of melting the butter.

[0003] Currently, to ensure the safe operation of the butter melting device, the water circulation pipeline adopts a completely sealed design. This prevents air from escaping. During the heating process, the water and air inside the pipeline expand due to heat. Since air is much more compressible than water, the difference in their expansion rates causes an uneven increase in pressure within the pipeline. This uneven pressure distribution creates a pressure difference inside the pipeline. According to fluid mechanics principles, this pressure difference disrupts the originally stable flow of water, leading to unstable flow within the pipeline. Furthermore, water is much denser than air, causing air to naturally rise as it flows within the pipeline. Under the continuous action of pressure difference, the flow rate inside the pipe is uneven, and air is gradually squeezed into specific areas inside the pipe, such as the high points or local narrow points of the pipe. Over time, the air in these areas continues to accumulate, eventually forming a thin layer of air on the inner wall of the pipe. Since the thermal conductivity of air is significantly lower than that of water, this air layer acts as a heat insulation barrier, greatly hindering the transfer of heat from hot water to the pipe wall and the butter, reducing the butter's melting efficiency. Moreover, the uneven distribution of the air layer will cause the butter to be heated unevenly, further adversely affecting the butter's melting efficiency. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides, for example Figure 1-2 A rapid venting device for a butter melting tank, as shown, includes:

[0022] A jacketed water tank 1, one end of which is connected to a plate heat exchanger 3 via a first connecting pipe 2, the plate heat exchanger 3 being connected to a grease melting tank 5 via a first circulation pipe 4, and the grease melting tank 5 being connected to the jacketed water tank 1 via a second circulation pipe 6;

[0023] The exhaust pipe 7 is connected to one side of the top of the jacketed water tank 1 and is used to discharge the gas in the jacketed water tank 1. The exhaust pipe 7 is equipped with a switch valve 8. The air inlet 21 of the switch valve 8 is connected to the jacketed water tank 1, and the air outlet 22 is connected to the exhaust pipe 7.

[0024] The switching valve 8 is connected to a sealing seat 9, and a sealing block 11 is provided inside the switching valve 8 and at the top of the sealing seat 9 for sealing the opening 10 in the middle of the sealing seat 9.

[0025] The top of the switch valve 8 is provided with a threaded cylinder 23 and a valve stem 12 is threadedly connected to the threaded cylinder 23. One end of the valve stem 12 is rotatably connected to the sealing block 11. A sealing ring is provided at the threaded connection between the valve stem 12 and the threaded cylinder 23, which can effectively seal the threaded connection and prevent air leakage.

[0026] The sealing block 11 is connected to a sealing gasket 13, which is made of rubber and can effectively seal the opening 10 in the sealing seat 9.

[0027] The jacketed water tank 1 is connected to a soft water pipe 14, and the first connecting pipe 2 is connected to a drain pipe 15, which is equipped with a safety valve 20. During the operation of the device, if the pressure in the pipeline becomes too high due to some reason (such as poor venting or abnormal increase in steam pressure), the safety valve 20 will automatically open when the pressure reaches the set opening pressure value of the safety valve 20. At this time, some circulating water will be discharged from the drain pipe 15, thereby reducing the pressure in the pipeline. When the pressure drops to the closing pressure value of the safety valve 20, the safety valve 20 will automatically close and stop draining. In this way, the safety valve 20 can effectively prevent the pipeline from rupturing due to excessive pressure and other safety accidents, ensuring the safe and stable operation of the equipment.

[0028] The first connecting pipe 2 is also equipped with a water pump 16.

[0029] The plate heat exchanger 3 is connected to a steam inlet pipe 17 and a steam outlet pipe 18 at its two ends, respectively.

[0030] The butter melting tank 5 is connected to a butter delivery pipe 19. When butter needs to be melted, the butter melting tank 5 is opened and the butter is poured onto the heating coil inside the butter melting tank 5, so that it can be melted by hot circulating water. The melted butter can be transported to an external collection device through the butter delivery pipe 19.

[0031] The butter melting tank uses a rapid exhaust device. A certain amount of circulating soft water can be injected into the jacketed water tank 1 through the soft water pipe 14. When the water pump 16 is working, the circulating water in the jacketed water tank 1 flows along the first connecting pipe 2 and enters the plate heat exchanger 3 to enter the heat exchange stage. The working principle of the plate heat exchanger 3 is based on heat conduction. Steam enters the plate heat exchanger 3 from the steam inlet pipe 17. The steam carries a large amount of heat energy. Inside the plate heat exchanger 3, the steam and the circulating water are separated by multiple layers of thin metal plates. The metal plates have good thermal conductivity. The heat of the steam is transferred to the circulating water through the metal plates, which raises the temperature of the circulating water. After the steam releases heat, it condenses into water and is discharged from the steam outlet pipe 18.

[0032] The heated circulating water flows out from the plate heat exchanger 3 and enters the butter melting tank 5 through the first circulation pipe 4. The butter to be melted can be poured into the heating coil inside the butter melting tank 5 by opening the butter melting tank 5. The heating coil is connected to the first circulation pipe 4. The circulating water in the first circulation pipe 4 transfers heat to the butter through heat conduction. Due to the good heat conduction performance of water, the butter absorbs heat and gradually changes from solid to liquid to complete the melting. The temperature of the circulating water that has completed the heat transfer drops, and then flows back into the jacketed water tank 1 through the second circulation pipe 6 to prepare for the next round of heating cycle. This cycle continues continuously, providing heat for the butter melting. The melted butter can be transported to the external collection device through the butter delivery pipe 19.

[0033] Before the device is used for the first time or restarted after a long period of inactivity, air is usually present in the pipeline. At this time, the valve stem 12 is in its initial state, the sealing block 11 is tightly fitted onto the opening 10 in the middle of the sealing seat 9, and the switch valve 8 is in the closed state. When preparing to inject soft water into the device, the worker manually rotates the valve stem 12 inside the threaded cylinder 23 to move it upward. The movement of the valve stem 12 causes the sealing block 11 to move upward, separating the sealing block 11 from the sealing seat 9. The switch valve 8 then opens, connecting the air inlet 21 and the air outlet 22.

[0034] After the soft water is injected, the water flows into the jacketed water tank 1 from the soft water pipe 14 and flows inside the tank. Since the exhaust pipe 7 is connected to the jacketed water tank 1 through the open switch valve 8, the flow of water in the jacketed water tank 1 will compress the air. Driven by the water flow, the air enters the switch valve 8 from the jacketed water tank 1 through the air inlet 21, then flows through the opening 10 to the air outlet 22 and enters the exhaust pipe 7, and is finally discharged outside the device. As the soft water is continuously injected, the air in the exhaust pipe 7 and the jacketed water tank 1 is gradually squeezed out by the water flow, realizing the exhaust operation before water injection and operation, thereby avoiding the accumulation of air in the pipeline.

[0035] When venting is required during the operation of the butter melting device, the different degrees of thermal expansion of circulating water and air will cause uneven pressure rise in the jacketed water tank 1, and air will gradually accumulate in the jacketed water tank 1. When the pressure sensor (not shown in the attached figure) installed in the jacketed water tank 1 detects an abnormal increase in pressure in the jacketed water tank 1, it determines that there may be excessive air accumulation and controls the alarm (not shown in the attached figure) on the jacketed water tank 1 to sound an alarm. The worker can manually turn the valve stem 12 to open the opening 10 to vent the air. As the air is vented, the pressure in the jacketed water tank 1 gradually returns to normal. When the pressure returns to the normal range (which can also be detected by the pressure sensor), the worker can manually turn the valve stem 12 to move it into the switch valve 8, causing the sealing block 11 to move downward and re-fit tightly against the opening 10 of the sealing seat 9, close the switch valve 8, and stop venting.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
