Description

Technical Field

[0001] The present application relates to the field of liquid product processing, and in particular to a vacuum degassing device. Background Art

[0002] Air is usually mixed into the liquid food during processing, which can easily cause food oxidation, discoloration, inconsistency, unpleasant odor and filling difficulties. The degassing device is a commonly used machine in the processing of some fruit and vegetable juices and milk beverages. It uses an air pump to discharge the non-condensable gas contained in the liquid to prevent the bubbles generated during filling and high-temperature sterilization from affecting the filling and high-temperature sterilization.

[0003] In conventional degassing devices, juice is mostly fed into the tank through an external pump structure before degassing. During the input process, due to the delivery pipeline and pressure, the juice is prone to a large collision with the inside of the tank, which makes it easier to generate bubbles, resulting in poor degassing effect. Utility Model Content

[0004] In order to reduce the generation of bubbles and improve the degassing efficiency, the present application provides a vacuum degassing device.

[0005] The vacuum degassing equipment provided in this application adopts the following technical solution:

[0006] A vacuum degassing device comprises a degassing tank, an exhaust mechanism arranged on the degassing tank, a heating mechanism and a cooling mechanism for cooling the precipitated gas, wherein the degassing tank is connected with a material inlet pipe and a material outlet pipe at intervals, one end of the material inlet pipe extends into the degassing tank and is arranged close to the tank wall of the degassing tank, and the material enters the degassing tank tangentially through the material inlet pipe.

[0007] By adopting the above technical scheme, the material inlet pipe is arranged in the degassing tank close to the tank wall, so that the material entering the degassing tank can enter the degassing tank in a tangential manner close to the tank wall. Compared with the direct entry of the material, the bubbles generated by the material impacting the tank wall are effectively reduced, and the degassing effect is improved; the setting of the exhaust mechanism can, on the one hand, draw the inside of the degassing tank into a negative pressure state, and on the other hand, draw out the precipitated gas; the setting of the heating mechanism can cooperate with the exhaust mechanism to reduce the solubility of the gas; the setting of the cooling mechanism can liquefy the precipitated gas in time and discharge it from the degassing tank.

[0008] Optionally, a diverter pipe for diverting materials and a guide plate for guiding the materials are provided in the degassing tank, the material inlet pipe is connected to the diverter pipe, and the material in the diverter pipe enters the degassing tank tangentially through the guide plate.

[0009] By adopting the above technical scheme, the setting of the diverter pipe can divert the material entering the degassing tank through the material inlet pipe to various positions of the degassing tank; the setting of the guide plate can make the material diverted by the diverter pipe enter the interior of the degassing tank tangentially along the tank wall of the degassing tank, so that the material forms a thin film on the inner wall of the tank, reducing the impact of the material on the tank body, reducing the generation of bubbles in the material, and improving the degassing effect.

[0010] Optionally, the diverter pipe is arranged in a ring shape along the circumference direction of the degassing tank, the guide plate is connected to the bottom of the diverter pipe, and a gap is formed between the guide plate and the inner wall of the degassing tank for materials to pass through.

[0011] By adopting the above technical solution, after the material enters the diversion pipe through the material inlet pipe, it will reach various positions of the degassing tank along the length direction of the diversion pipe. While the material flows horizontally, the material will also continuously flow downward along the guide plate close to the inner wall of the degassing tank.

[0012] Optionally, the guide plate is arranged at an angle, and an end of the guide plate away from the diversion pipe is arranged in a direction close to the inner wall of the degassing tank.

[0013] By adopting the above technical solution, the inclined setting of the guide plate allows the material entering the gap between the guide plate and the degassing tank to move obliquely downward toward the inner wall of the degassing tank, so that the material moves more closely against the inner wall of the degassing tank.

[0014] Optionally, a flow balancing mechanism is provided at the bottom of the degassing tank, and the material inlet pipe and the material outlet pipe are respectively connected to the flow balancing mechanism.

[0015] By adopting the above technical solution and setting the flow balancing mechanism, the material feeding speed can be adjusted by means of the material discharging speed, thereby reducing the situation where the degassing effect is poor due to the excessively fast material feeding speed.

[0016] Optionally, a three-way valve is connected to one end of the material inlet pipe away from the degassing tank, and the flow balancing mechanism includes a first rotating rod rotatably connected to the three-way valve, the first rotating rod is used to close or open the feed valve port of the three-way valve, and a control component for controlling the rotation of the first rotating rod is arranged between the three-way valve and the material outlet pipe.

[0017] By adopting the above technical solution, the coordinated arrangement of the control component and the first rotating rod can drive the first rotating rod to rotate at the feed valve port to open or close the feed valve port, so that when the feed valve port is closed, the material cannot enter the degassing tank, and when the feed valve port is opened, the material can enter the degassing tank, thereby achieving control over the material feeding.

[0018] Optionally, a fixed cylinder connected to the feed valve port is provided in the three-way valve, the first rotating rod is rotatably connected in the fixed cylinder, a sliding hole is provided on the fixed cylinder for one end of the first rotating rod to extend and slide, and an elastic part is provided on the fixed cylinder to cooperate with the first rotating rod to close the sliding hole.

[0019] By adopting the above technical solution, the first rotating rod and the elastic member cooperate with each other to change the diameter of the sliding hole. When the diameter length of the sliding hole is the same as the diameter length of the first rotating rod, the first rotating rod together with the elastic member just closes the sliding hole, thereby preventing the material from entering the three-way valve through the feed valve port.

[0020] Optionally, the elastic member includes an elastic plate and a spring connected between the elastic plate and the fixed tube, the outer wall of the elastic plate abuts against the outer wall of the first rotating rod, and the inner wall of the elastic plate abuts against one end of the fixed tube.

[0021] By adopting the above technical solution, when the first rotating rod rotates to form an angle with the horizontal plane, the spring is compressed and the elastic plate moves accordingly. At this time, the sliding hole is partially opened, and the material enters the three-way valve; when the first rotating rod rotates to be parallel to the horizontal plane, the spring extends and drives the elastic plate to reset. At this time, the first rotating rod and the elastic plate jointly close the sliding hole, and the material cannot enter the three-way valve.

[0022] Optionally, the flow balancing mechanism also includes a flow balancing box connected between the three-way valve and the material outlet pipe, the flow balancing box is connected to the material outlet pipe, and the control component includes a second rotating rod hinged in the flow balancing box, one end of the second rotating rod is hinged to one end of the first rotating rod, and the other end of the second rotating rod extends into the flow balancing box and is connected to a float valve.

[0023] By adopting the above technical solution, the float valve can change its own position with the help of the amount of material discharged from the flow balance box, so as to achieve the rotation of the first rotating rod driven by the rotation of the second rotating rod, and then achieve the closing or opening of the sliding hole to control the entry of materials.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. The material inlet pipe is set close to the wall of the degassing tank inside the degassing tank, so that the material enters the degassing tank tangentially through the material inlet pipe. Compared with the direct impact of the material on the wall of the degassing tank, fewer bubbles are generated, which effectively improves the degassing effect;

[0026] 2. Through the coordinated arrangement of the diverter pipe and the guide plate, the material can first flow to various positions of the degassing tank after entering the degassing tank, and then slide down along the guide plate close to the inner wall of the degassing tank in a tangential manner, thereby effectively reducing the bubbles generated by the direct impact of the material on the degassing tank;

[0027] 3. Through the coordinated setting of the first rotating rod, the second rotating rod and the floating ball valve, the material feeding speed can be adjusted by the material discharging speed, reducing the influence of the material feeding too fast on the degassing effect; BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The following is combined with Figure 1-7 This application is described in further detail.

[0037] The embodiment of the present application discloses a vacuum degassing device.

[0038] Embodiment 1:

[0039] Reference Figure 1 and Figure 2 The vacuum degassing equipment includes a support frame 1, a degassing tank 2 fixedly connected to the support frame 1, a feeding mechanism 3 arranged on the degassing tank 2, an exhaust mechanism 4 connected to the top of the degassing tank 2, and a discharging mechanism 5 connected to the bottom of the degassing tank 2. The degassing tank 2 is also provided with a cooling mechanism 6 for cooling the liquefied precipitated gas.

[0040] Reference Figure 1 , Figure 2 and Figure 3 The feeding mechanism 3 includes a material inlet pipe 31 that penetrates and is fixed to the middle of the wall of the degassing tank 2. One end of the material inlet pipe 31 extends into the degassing tank 2 and bends toward the bottom of the degassing tank 2. The wall of the material inlet pipe 31 abuts against the wall of the degassing tank 2. When in use, the material enters the material inlet pipe 31, and then enters the degassing tank 2 tangentially along the direction of the material inlet pipe 31. The material flows downward in the direction of the wall of the degassing tank 2, reducing the bubbles generated by the direct impact of the material on the degassing tank 2, and then the material is discharged from the discharging mechanism 5 after degassing.

[0041] Reference Figure 1 The discharging mechanism 5 includes a material discharging pipe 51 which is fixed to the bottom of the degassing tank 2 and communicated with the interior of the degassing tank 2 .

[0042] In order to control the material feeding speed and reduce the impact of excessive material feeding on the degassing effect, refer to Figure 2 A flow balancing mechanism 7 is also provided between the material inlet pipe 31 and the material outlet pipe 51. The flow balancing mechanism 7 timely adjusts the material feed speed by judging the material discharge speed to balance the flow of the inlet and outlet materials.

[0043] Reference Figure 2 and Figure 4 The flow balance mechanism 7 includes a flow balance box 71 with a triangular cross section. A three-way valve 72 is fixedly connected to one end of the flow balance box 71. The end of the material inlet pipe 31 away from the degassing tank 2 extends to the bottom of the degassing tank 2 and is fixedly connected to a valve port of the three-way valve 72. The side wall of the flow balance box 71 facing the three-way valve 72 is fixedly connected to and connected with the side wall of the material outlet pipe 51. When in use, the material enters from a valve port of the flow balance box 71 facing the three-way valve 72, and then enters the material inlet pipe 31 through the other valve port. The material entering the three-way valve 72 cannot enter the flow balance box 71.

[0044] Reference Figure 2 and Figure 4The flow balancing mechanism 7 further includes a first rotating rod 73 rotatably connected to the three-way valve 72 and a control member 74 for controlling the rotation of the first rotating rod 73. When in use, the first rotating rod 73 rotates to close and open a valve port (hereinafter referred to as the feed valve port 721) on the three-way valve 72 for material to enter.

[0045] A fixed cylinder 722 is fixedly connected in the three-way valve 72 near the feed valve port 721, and one end of the fixed cylinder 722 is connected to the feed valve port 721. The first rotating rod 73 is rotatably connected in the fixed cylinder 722, and a sliding hole 723 is provided at one end of the fixed cylinder 722 away from the feed valve port 721 for the one end of the first rotating rod 73 away from the feed valve port 721 to extend out, and the diameter length of the sliding hole 723 is greater than the diameter length of the first rotating rod 73.

[0046] In order to cooperate with the first rotating rod 73 to close or open the sliding hole 723, so that the material enters or stops entering the three-way valve 72, an elastic member is also provided at the sliding hole 723. Figure 2 and Figure 4 The elastic member includes an L-shaped elastic plate 724 located on the side of the first rotating rod 73 facing the material inlet pipe 31. One end of the elastic plate 724 extends into the sliding hole 723 and is connected to the wall of the fixed cylinder 722 through a spring 725. When in use, the outer wall of one side of the elastic plate 724 always abuts against the outer wall of one side of the first rotating rod 73, and the inner wall of one side of the elastic plate 724 always abuts against the outer wall of the fixed cylinder 722 around the sliding hole 723. When the first rotating rod 73 rotates to a horizontal position, the spring 725 is in an extended state, and the elastic plate 724 and the first rotating rod 73 just close the sliding hole 723, and the material stops entering the three-way valve 72; when the first rotating rod 73 rotates toward the direction of the elastic plate 724, the spring 725 will be squeezed, driving the elastic plate 724 to move upward, and at this time the sliding hole 723 is partially opened, and the material enters the three-way valve 72.

[0047] Reference Figure 2 and Figure 4, the valve port at the connection between the flow balance box 71 and the three-way valve 72 is closed. The control member 74 includes a second rotating rod 741 rotatably connected to the connection between the flow balance box 71 and the three-way valve 72, one end of the second rotating rod 741 extends into the three-way valve 72 and is hinged together with one end of the first rotating rod 73, and the other end of the second rotating rod 741 extends into the flow balance box 71 and is fixedly connected with a float valve 742. When in use, when the discharge speed is too fast, the material in the flow balance box 71 also increases. At this time, the float valve 742 floats up and drives the other end of the second rotating rod 741 to move down, and then drives the first rotating rod 73 to move down. When the first rotating rod 73 moves to a horizontal state, the slide hole 723 is closed and the material stops entering; when the discharge speed is too slow, the float valve 742 moves down and drives the other end of the second rotating rod 741 to move up, and then drives the end of the first rotating rod 73 hinged with it to move up. At this time, the spring 725 is compressed, the slide hole 723 is partially opened, and the material enters.

[0048] Reference Figure 1 The exhaust mechanism 4 includes an exhaust pipe 41 passing through and fixedly connected to the top of the degassing tank 2 and a vacuum pump 42 installed at one end of the exhaust pipe 41 away from the degassing tank 2. When in use, the vacuum pump 42 first extracts the gas inside the degassing tank 2, thereby reducing the gas pressure inside the degassing tank 2, so that the solubility of the material entering the degassing tank 2 is reduced, which is conducive to the precipitation of gas.

[0049] Reference Figure 1 and Figure 2 The degassing tank 2 is provided with an inclined cooling chamber 21, the slope of which gradually decreases from the side close to the material inlet pipe 31 to the side away from the material inlet pipe 31, and the cooling chamber 21 is located on the side of the diverter pipe 52 facing the top of the degassing tank 2. One end of the exhaust pipe 41 extending into the degassing tank 2 is fixedly connected to the top of the cooling chamber 21 and communicated with the inside of the cooling chamber 21. The exhaust pipe 41 is located near the higher end of the slope of the cooling chamber 21, and a gas hole for gas to pass through is provided at the bottom of the cooling chamber 21 and near the higher end of the slope.

[0050] Reference Figure 1 and Figure 2 The cooling mechanism 6 includes a cooling pipeline 61 arranged in the cooling chamber 21. One end of the cooling pipeline 61 enters the cooling chamber 21 through the side wall of the degassing tank 2 and the top of the cooling chamber 21 at a higher slope, and is arranged around the length direction of the first cooling chamber 21. The other end of the cooling pipeline 61 passes through the top of the cooling chamber 21 at a lower slope and exits the top of the degassing tank 2. When in use, the gas precipitated from the material is extracted into the cooling chamber 21 under the action of the vacuum pump 42, and ice water flows into the cooling chamber 21 through the cooling pipeline 61, so that the gas entering the cooling chamber 21 is cooled and liquefied to form liquid.

[0051] Reference Figure 2A drain pipe 22 is fixedly connected to the side wall of the degassing tank 2. One end of the drain pipe 22 extends into the interior of the degassing tank 2 and communicates with the lower end of the cooling chamber 21. An air pump and a waste liquid tank 24 for collecting waste liquid are provided at one end of the drain pipe 22 away from the degassing tank 2. When in use, the gas entering the cooling chamber 21 is cooled and liquefied to form liquid, and the liquid flows into the drain pipe 22 along the slope of the cooling chamber 21, thereby being discharged from the degassing tank 2.

[0052] In order to reduce the solubility of the gas and improve the degassing effect, the degassing tank 2 is also provided with a heating mechanism 8 for heating the material. The heating mechanism 8 heats the tank wall of the degassing tank 2 so that the temperature of the tank wall is higher than the temperature of the material in the degassing tank 2, thereby generating heat exchange with the material and reducing the solubility of the gas therein. Figure 1 and Figure 2 The heating mechanism 8 includes a heating pipeline 81 disposed in the side wall of the degassing tank 2. The heating pipeline 81 penetrates from the bottom of the degassing tank 2 into the inside of the side wall of the degassing tank 2, and spirally rises along the height direction of the degassing tank 2 until it penetrates to the top of the degassing tank 2. When in use, after the vacuum pump 42 evacuates the degassing tank 2 to a vacuum state, water with a relatively high temperature is introduced into the heating pipeline 81 from the bottom of the degassing tank 2. The water flow spirally rises along the side wall of the degassing tank 2 to heat the degassing tank 2. At this time, the material flows down tangentially along the guide plate 53 close to the inner wall of the degassing tank 2, which can maximize heat exchange, thereby increasing the temperature of the material and allowing bubbles in the material to precipitate.

[0053] The implementation principle of a vacuum degassing device in Example 1 of the present application is as follows: when in use, in the initial state, there is no material in the flow balance box 71, at this time, the float valve 742 falls to the bottom of the flow balance box 71, and the first rotating rod 73 rotates to partially open the slide hole 723, and the material is injected into the material inlet pipe 31 through the feed valve port 721 of the three-way valve 72, and the material entering the material inlet pipe 31 flows tangentially into the degassing tank 2 close to the inner wall of the degassing tank 2; the vacuum pump 42 is started to pump the inside of the degassing tank 2 to a negative pressure, and then water with a higher temperature is introduced into the heating pipeline 81. At this time, the solubility of the gas in the material is reduced and precipitated, and enters the cooling chamber 21 under the action of the vacuum pump 42, and ice water continuously passes through the cooling pipeline 61 in the cooling chamber 21. The precipitated gas is liquefied after being cooled to form a liquid and is discharged from the degassing tank 2, and the degassed material is discharged through the material outlet pipe 51. During the material discharge process, when the discharge speed is too fast, the increase of materials in the flow balance box 71 will cause the float valve 742 to float up. At this time, the first rotating rod 73 rotates to close the slide hole 723, and the feeding is temporarily stopped until the material discharge speed returns to normal. Through a vacuum degassing device, the design of the material inlet pipe 31 abutting against the wall of the degassing tank 2 makes the material close to the wall of the degassing tank 2 after entering the degassing tank 2 and flows down tangentially. Compared with the material directly entering the degassing tank 2, the generation of bubbles is reduced and the degassing effect is improved.

[0054] Embodiment 2:

[0055] The difference between this embodiment and embodiment 1 is that the feeding mechanism 3 further includes a diverter pipe 52 for diverting materials and a guide plate 53 for guiding the materials.

[0056] Reference Figure 5 , Figure 6 and Figure 7 , the diverter plate is arranged horizontally around the inner wall of the degassing tank 2. One end of the material inlet pipe 31 extends into the interior of the degassing tank 2 and communicates with the top of the diverter pipe 52. The diverter pipe 52 is fixedly connected to the inner wall of the degassing tank 2, and a circle of guide plates 53 are vertically fixedly connected to the diverter pipe 52 on one side of the diverter pipe 52 facing the bottom of the degassing tank 2 around its circumferential direction. The guide plate 53 is arranged at half the length of the diameter of the bottom of the diverter pipe 52, and the end of the guide plate 53 away from the annular plate extends toward the inner wall of the degassing tank 2 and leaves a gap. A diverter port 521 is provided at the bottom of the diverter pipe 52 to connect the gap formed by the guide plate 53 and the degassing tank 2. When in use, the material flows into the shunt pipe 52 through the material inlet pipe 31, and the material flowing into the shunt pipe 52 flows horizontally along the length direction of the shunt pipe 52. During the flow, the material continuously flows along the guide plate 53 and along the tank wall of the degassing tank 2 to the tank bottom of the degassing tank 2, so that the material can enter the degassing tank 2 tangentially, reducing the bubbles generated by the direct impact of the material on the degassing tank 2, and then the material is discharged from the discharge mechanism 5 after degassing.

[0057] The implementation principle of a vacuum degassing device in Example 2 of the present application is as follows: when in use, in the initial state, there is no material in the flow balance box 71, at this time, the float valve 742 falls to the bottom of the flow balance box 71, and the first rotating rod 73 rotates to partially open the slide hole 723, and the material is injected into the material inlet pipe 31 through the feed valve port 721 of the three-way valve 72, and the material entering the material inlet pipe 31 flows into the diverter pipe 52 inside the degassing tank 2, and the material goes around to various parts of the degassing tank 2 along the circumferential direction of the diverter pipe 52, and passes through this process. During the process, materials continuously flow downward tangentially along the slope of the guide plate 53 and close to the inner wall of the degassing tank 2; the vacuum pump 42 is started to pump the inside of the degassing tank 2 to negative pressure, and then water with a higher temperature is introduced into the heating pipeline 81. At this time, the solubility of the gas in the material is reduced and precipitated, and enters the cooling chamber 21 under the action of the vacuum pump 42. Ice water continuously passes through the cooling pipeline 61 in the cooling chamber 21. The precipitated gas is liquefied after being cooled to form liquid and discharged from the degassing tank 2. The degassed material is discharged through the material outlet pipe 51. During the material discharging process, when the discharging speed is too fast, the increase of materials in the flow balance box 71 will cause the float valve 742 to float. At this time, the first rotating rod 73 rotates to close the slide hole 723, and the feeding is temporarily stopped until the material discharging speed returns to normal. Through a vacuum degassing device, especially the setting of the diverter plate and the guide plate 53, the material can fall tangentially into the degassing tank 2 in all directions and close to the tank wall of the degassing tank 2 after entering the degassing tank 2. Compared with the material directly entering the degassing tank 2, the generation of bubbles is reduced and the degassing effect is improved.

[0058] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
