[0002] In the Chinese medicine extraction workshop, the generation of steam accounts for a large cost item in the Chinese medicine extraction production, because it involves links such as steam consumption concentration and waste heat utilization. As energy conservation and emission reduction are the definite needs of enterprises, there is a lot of room for improvement in the utilization of steam.

[0003] Existing steam collection is often operated through a customized recovery system. Since the open steam recovery system recovers condensed water, the condensed water will be contaminated again after contacting the atmosphere. The re-dissolution of oxygen will cause corrosion inside and outside the piping system and changes in conductivity, shortening the service life of the equipment. Therefore, most companies use closed systems, which are usually closed return pumps or closed boilers. Due to the existence of airtightness, the pressure difference of the steam trap always exists, affecting the steam pressure given at the front end, affecting work efficiency, and poor reliability.

[0018] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] like Figure 1-2 As shown together, this embodiment is about the steam condensate water level balancing device, including a steam condensate tank 1 connected to a front-end given device. The specific connection position of the connecting pipe of the given device is located above the waist of the steam condensate tank 1 to ensure the storage of steam condensate in the steam condensate tank 1. It can be understood that steam condensate is contained in the steam condensate tank 1.

[0020] The opening at the bottom of the steam condensation tank 1 is clamped with a straight plug-in tube 4 through a two-way plug-in elbow 2, and the other end of the plug-in tube 4 is clamped with a three-way plug-in elbow 5. The three-way plug-in elbow 5 is also connected to an overflow plug 6 located at its side and an extension tube 10 extending vertically upward from the top of the three-way plug-in elbow 5. A plug 8 is movably fitted in the overflow plug 6. The free end of the extension tube 10 is connected to a balance container 11. A serpentine condenser 15 is installed in the steam condensation chamber 14 formed by the balancing container 11. One side of the steam condensation chamber 14 is also connected to a steam circulation tube 16 whose other end is connected to the top of the steam condensation tank 1.

[0021] Before the actual operation, a waterproof cloth is wrapped around the clamping joint between the two-way plug-in elbow 2 and the plug-in tube 4, and a waterproof cloth is also wrapped around the clamping joint between the three-way plug-in elbow 5 and the plug-in tube 4.

[0022] Preferably, the two-way plug-in elbow 2 is connected to the bottom opening of the steam condensate tank 1 through the clamp at its port and a sealing ring 3 is provided at the connection between the two, and the transition angle of the two-way plug-in elbow 2 is 90°; the sealing ring 3 is used to prevent water leakage at the connection, and the transition angle of the two-way plug-in elbow 2 is specifically limited to 90°, which is conducive to ensuring the setting of the rear-end connecting components.

[0023] The rear end connection component specifically refers to the plug-in tube 4, so the plug-in tube 4 and the steam condensate tank 1 are arranged parallel to each other. In other words, the plug-in tube 4 and the ground are arranged parallel to each other to prevent the steam condensate in the plug-in tube 4 from moving to one end under the action of gravity.

[0024] The three-way plug elbow 5 is U-shaped as a whole. Figure 1 As shown, it is specifically a U-shape rotated 90 degrees counterclockwise. It can be understood that the two ends of the U-shape of the three-way plug elbow 5 are respectively connected to the plug-in tube 4 and the overflow plug 6, and the flat bottom of the U-shape of the three-way plug elbow 5 is extended to connect the extension pipe 10.

[0025] The plug 8 is arranged at the opening on one side of the overflow plug 6 where the overflow plug 6 and the three-way plug elbow 5 are interconnected, and a spring 9 located on the rod body of the plug 8 is provided between the disk surface of the plug 8 and the wall surface of the overflow plug 6, and the other end of the rod body of the plug 8 is connected to the outside of the overflow plug 6 through.

[0026] Preferably, the spring 9 is implemented in a manner that it elastically deforms under the thrust of the steam condensate. When the liquid level of the steam condensate in the three-way plug elbow 5 rises and reaches the height of the overflow plug 6, the disk surface of the plug 8 is pushed to compress the spring 9 and deform under the thrust of the steam condensate. At this time, the overflow plug 6 is in an open and closed state, and the steam condensate exceeding the liquid level of the overflow plug 6 flows through the open and closed port to the overflow port 7 for discharge. When the liquid level of the steam condensate drops and the force pushing the disk surface of the plug 8 disappears, the spring 9 returns to its initial position, and the plug 8 again blocks the connection between the overflow plug 6 and the three-way plug elbow 5. In this process, not only can the excess steam condensate be discharged, but it is also beneficial to release the pressure, which is beneficial to maintaining the steam pressure and water level balance given by the front-end equipment, thereby ensuring the life of the device.

[0027] The balancing container 11 includes a retention cup 12 and an external connection pipe 13 extending into the cup body of the retention cup 12. The outer side of the retention cup 12 is fixedly connected to the tube wall of the external connection pipe 13 on the corresponding side, and welding is usually performed in the actual process. The retention cup 12 is used to ensure the internal pressure of the device of this embodiment to prevent adverse production defects caused by changes in the pressure difference between the internal pressure and the atmospheric pressure. It should be noted that the retention cup 12 and the part of the external connection pipe 13 extending into the cup body of the retention cup 12 are filled with water, and this part of the water also contains newly condensed steam condensate. When the water in the retention cup 12 overflows, the overflowing water falls into the three-way plug elbow 5 under the action of gravity.

[0028] The serpentine condenser 15 is installed on the ear plate extending outside the external connecting pipe 13 and directly above the extension pipe 10, and the steam circulation pipe 16 is arranged at an angle. Based on the above structure, the steam given by the front-end equipment first enters the steam condensate tank 1, and then floats upward through the steam circulation pipe 16 under the action of density. When the steam encounters the serpentine condenser 15 in the steam condensate chamber 14, it becomes steam condensate and drips into the three-way plug elbow 5 under the action of gravity.

[0029] In this way, the steam condensate water level balancing device disclosed in the utility model abolishes the traditional closed structure, condenses the steam given by the front-end equipment through a reasonably set steam condensation chamber, and is equipped with a balancing container for maintaining the internal pressure. The present application can realize semi-automatic operation to achieve the purpose of discharging excess steam condensate, thereby achieving the effect of releasing excess pressure and balancing the water level.

[0030] The above implementation modes are not limitations of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the technical solution of the present invention also belong to the protection scope of the present invention.
