Description

Technical Field

[0001] This utility model relates to the technical field of steam-water mixing devices in fine chemical industry, and in particular to an automatic temperature-regulating steam-water mixing device. Background Technology

[0002] Currently, in many fine chemical production processes, due to limited space and dense equipment arrangement during project construction, it is necessary to add traditional steam-water mixing devices during later process upgrades. However, traditional steam-water mixing devices are difficult to install because they have many pipes and occupy a large area.

[0003] Therefore, an automatic temperature-controlled water mixing device is provided for installation in confined spaces, and to achieve stable water mixing. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art and to provide an automatic temperature-controlled steam-water mixing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic temperature-controlled soda-water mixing device includes a mixing tube and further includes:

[0007] Metal packing material is disposed inside the mixing tube;

[0008] A rotating ring is connected inside the mixing tube;

[0009] A sliding groove is provided within the rotating ring;

[0010] The second spoiler is fixedly connected inside the mixing pipe;

[0011] Two sets of spoilers are slidably connected in the groove, and the spoilers are located on both sides of the spoilers.

[0012] Motor 1 is fixedly connected to the rotating ring. A lead screw is fixedly connected to the output end of Motor 1. Both sets of spoilers 1 are threadedly connected to the lead screw. By rotating the lead screw, the two sets of spoilers 1 can move closer to each other and further away.

[0013] To facilitate the use of mixing water and gas, preferably, the mixing pipe is provided with a water inlet pipe, a water outlet pipe, and an air inlet pipe. The air inlet pipe is connected to the metal packing and is used to inject gas into the metal packing. Both the water inlet pipe and the air inlet pipe are equipped with electronic control valves.

[0014] To facilitate adjustment of the spoiler's blocking range, preferably, a second motor is fixedly connected inside the mixing pipe, a gear is fixedly connected to the output end of the second motor, and a gear ring that meshes with the gear is fixedly connected to the rotating ring.

[0018] Compared with the prior art, the present invention provides an automatic temperature-regulating steam-water mixing device, which has the following beneficial effects:

[0019] This invention uses stainless steel metal packing material to ensure the durability and service life of the equipment. Steam enters the metal packing material, which can distribute the steam more evenly.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example:

[0027] Reference Figure 1-4 An automatic temperature-regulating steam-water mixing device includes a mixing pipe 1, and further includes: a metal packing 2 disposed inside the mixing pipe 1; a rotating ring 3 connected inside the mixing pipe 1; a chute 301 disposed inside the rotating ring 3; a second baffle 5 fixedly connected inside the mixing pipe 1; two sets of first baffles 4 slidably connected inside the chute 301, with the first baffles 4 located on both sides of the second baffle 5; a motor 601 fixedly connected to the rotating ring 3, with a lead screw 602 fixedly connected to the output end of the motor 601, and both sets of first baffles 4 threadedly connected to the lead screw 602. Through the rotation of the lead screw 602, the two sets of first baffles 4 can move closer to and further away from each other, thus mixing the steam-water mixture. Pipe 1 is equipped with an inlet pipe 101, an outlet pipe 102, and an air inlet pipe 103. The air inlet pipe 103 is connected to the metal packing 2 and is used to inject gas into the metal packing 2. Both the inlet pipe 101 and the air inlet pipe 103 are equipped with electronic control valves. A motor 701 is fixedly connected inside the mixing pipe 1. A gear 702 is fixedly connected to the output end of the motor 701. A gear ring 302 that meshes with the gear 702 is fixedly connected to the rotating ring 3. The metal packing 2 is made of stainless steel and has a honeycomb structure. A baffle 4 and a baffle 5 are located at the liquid outlet end of the metal packing 2. A thermometer 104 is installed at the outlet pipe 102 of the mixing pipe 1.

[0028] This device has a built-in PLC control system, which receives the temperature from thermometer 104 to control the electronic control valve. The electronic control valve then controls the amount of steam and water entering the device, thereby automating temperature control.

[0029] This device only requires one mixing tube 1 to achieve the mixing of soda and water. It is compact in size and suitable for installation and use in smaller areas.

[0030] During use, water is injected into the mixing pipe 1 through the water inlet pipe 101, and steam is injected into the metal packing 2 through the air inlet pipe 103. At this time, the water will enter the metal packing 2 and then mix with the steam. The mixed water will then come into contact with the subsequent baffles. It will first contact the first baffle 4, then the second baffle 5, and finally the last baffle 4. When the water flows through the baffles, vortices will be formed around the baffles. When the baffles are spaced close together, the vortices generated by adjacent baffles may interfere with each other and superimpose, increasing the turbulence of the water flow. This turbulence will consume the energy of the water flow, which will be macroscopically manifested as a decrease in the water flow velocity. When the spacing is larger, the vortices generated by each baffle are relatively independent, with less interference between them. The energy loss of the water flow is relatively small, and the velocity change is relatively small. This increases the contact time between the liquid and the steam, making the discharged water temperature more stable.

[0031] When in use, the water temperature can be monitored by thermometer 104. If the water temperature is low, the water temperature can be increased by reducing the water intake or increasing the air intake. Similarly, the water temperature can be decreased by increasing the water intake and decreasing the air intake.

[0032] Specifically, adjusting the distance between the spoilers can be achieved by starting motor 601, which causes the two sets of spoilers 4 to continuously move closer to spoiler 5, thereby reducing the distance between them. The eddies generated by the adjacent spoilers may interfere with and superimpose each other, increasing the turbulence of the water flow. This turbulence consumes the energy of the water flow, which macroscopically manifests as a decrease in water velocity. However, if the distance between the two spoilers is too close, it may cause a greater local flow velocity, making the liquid flow faster. If the liquid is viscous, the internal friction between liquid molecules is greater, and the change in liquid velocity when adjusting the spoiler spacing is relatively gradual. However, for some less viscous liquids such as water, the flow velocity is more significantly affected by the change in spoiler spacing, and the liquid can respond more quickly to changes in the flow channel. Specific applications require adjustments based on the actual liquid and the shape and surface curvature of the spoilers.

[0033] In an ideal state, when only water is being mixed with steam, the distance between the baffles allows for adjustment of the liquid's flow rate, enabling the choice between further increasing the mixing time or quickly discharging the liquid for easier use.

[0034] When in use, the common coverage area between the spoilers can also be adjusted by using motor 2701. The coverage area refers to the overlapping area between the two when viewed directly. The larger the coverage area, the greater the interference with the water, and the smaller the coverage area, the less interference with the water. The flow speed of the liquid can also be adjusted in this way.

[0035] This utility model uses stainless steel metal packing 2 to ensure the durability and service life of the equipment. Steam enters the metal packing 2, which can distribute the steam more evenly. The hot water that has been initially mixed in the steam and water mixing zone enters the baffle area of ​​the device. The baffle can mix the hot water more thoroughly, making the outlet water temperature more stable. The spacing between the baffles can be adjusted to adjust the water flow discharge speed.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
