Description

Technical Field

[0001] This utility model relates to the technical field of graphite evaporators, specifically a high-pressure resistant graphite evaporator. Background Technology

[0002] The evaporator is a crucial component of the four main refrigeration systems. Low-temperature condensed liquid passes through the evaporator, exchanging heat with the outside air, vaporizing and absorbing heat to achieve a cooling effect. The evaporator mainly consists of a heating chamber and an evaporation chamber. Graphite evaporators are widely used in the pharmaceutical and chemical industries. Due to their advantages such as high temperature resistance, corrosion resistance, high pressure resistance, and good thermal conductivity, graphite evaporators are often used to evaporate and concentrate acidic and alkaline liquids.

[0003] The current use of graphite evaporators still has certain shortcomings. They cannot adaptively adjust the pressure inside the evaporator. When the pressure inside the evaporator is too high, it will aggravate the scouring and squeezing of the graphite heat exchange blocks by the steam, thereby accelerating the damage of the graphite heat exchange blocks, increasing the cost of use, and reducing the service life of the evaporator's structural strength. Therefore, an anti-scouring graphite evaporator is needed to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a high-pressure resistant graphite evaporator to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-pressure resistant graphite evaporator includes an evaporator with a feed pipe at its top and a discharge pipe at its bottom. The evaporator contains several graphite heat exchange blocks. A steam inlet pipe and a steam outlet pipe are located on both sides of the evaporator. Pressure control pipes are installed on both sides of the top and bottom of the evaporator. A soft-rebound elastic element is installed on the inner wall of the end of the pressure control pipe furthest from the evaporator. A piston plate is installed on the end of the soft-rebound elastic element closest to the evaporator. The outer wall of the piston plate slides against the inner wall of the pressure control pipe. A buffer assembly is installed inside the steam inlet pipe.

[0007] As a further improvement of this utility model: a connecting horizontal pipe is connected between the two upper pressure control pipes and between the two lower pressure control pipes, and the connection between the connecting horizontal pipe and the side of the pressure control cylinder is located on the side of the piston plate near the soft-rebound elastic element.

[0008] As a further improvement of this utility model, the middle portions of the two connecting horizontal tubes are respectively connected to the two ends of the connecting vertical tube.

[0009] As a further embodiment of this utility model: the buffer assembly includes a rotating rod and a rotating plate installed inside the steam inlet pipe, the two ends of the rotating rod being rotatably connected to the inner walls of both sides of the steam inlet pipe, and the middle part of the rotating plate being connected to the middle part of the rotating rod.

[0010] As a further improvement of this utility model: the rotating rods are configured as two that are distributed vertically and staggered horizontally, and the length of the rotating plate is half the height of the inner cavity of the steam inlet pipe.

[0011] As a further embodiment of this utility model: several reinforcing horizontal plates are arranged vertically inside the evaporator, the outer wall of the reinforcing horizontal plates is connected to the inner wall of the evaporator, and the middle part of the graphite heat exchange block is interlocked with the reinforcing horizontal plates.

[0012] The present invention has the following advantages: the evaporator regulates the internal pressure of the evaporator through a pressure control tube. When the pressure inside the evaporator is too high, the piston plate will squeeze the elastic element to achieve automatic adjustment of the pressure inside the evaporator. The buffer component turbulently buffers the steam in the steam inlet pipe, preventing the steam from directly impacting the graphite heat exchange block and causing a sudden increase in the pressure inside the evaporator. The overall evaporator structure is simple and easy to install. Each component is easy to replace and install, making it more practical. Attached Figure Description

[0017] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.

[0018] Example 1: Please refer to Figures 1 to 3A high-pressure resistant graphite evaporator 1 includes an evaporator 1, with a feed pipe 101 and a discharge pipe 102 respectively provided at the top and bottom ends of the evaporator 1. The evaporator 1 is equipped with a plurality of graphite heat exchange blocks 7. A steam inlet pipe 103 and a steam outlet pipe 104 are respectively provided on both sides of the evaporator 1. Pressure control pipes 3 are installed on both sides of the top and bottom of the evaporator 1. A soft-rebound elastic element 301 is installed on the inner wall of the end of the pressure control pipe 3 away from the evaporator 1. A piston plate 302 is installed on the end of the soft-rebound elastic element 301 close to the evaporator 1. The outer wall of the piston plate 302 slides against the inner wall of the pressure control pipe 3. A buffer assembly 2 is installed inside the steam inlet pipe 103.

[0019] Please see Figure 1 , Figure 2 A horizontal connecting pipe 4 is connected between the two upper pressure control pipes 3 and between the two lower pressure control pipes 3. The connection point of the horizontal connecting pipe 4 to the side of the pressure control cylinder is located on the side of the piston plate 302 near the soft-rebound elastic element 301. The soft-rebound elastic element 301 can be a shock-absorbing damping spring. The middle part of the two horizontal connecting pipes 4 is connected to both ends of the vertical connecting pipe 5, so that the pressure adjustment changes in the four pressure control cylinders are consistent, ensuring the pressure control stability of the overall evaporator 1.

[0020] Example 2: See Figure 1 In embodiment 3, based on embodiment 1, the buffer assembly includes a rotating rod 201 and a rotating plate 202 installed inside the steam inlet pipe 103. The two ends of the rotating rod 201 are rotatably connected to the inner walls of both sides of the steam inlet pipe 103. The middle part of the rotating plate 202 is connected to the middle part of the rotating rod 201. The rotating rod 201 is arranged in two vertically distributed and horizontally staggered positions. The length of the rotating plate 202 is half the height of the inner cavity of the steam inlet pipe 103. The two rotating plates 202 are staggered to improve the buffering effect.

[0021] Please see Figure 1 The evaporator 1 has several reinforcing horizontal plates 6 arranged vertically inside it. The outer wall of the reinforcing horizontal plate 6 is connected to the inner wall of the evaporator 1. The middle part of the graphite heat exchange block 7 is interlocked with the reinforcing horizontal plate 6.

[0022] Working principle: When in use, steam enters the evaporator 1 through the steam inlet pipe 103. After passing through the rotating plate 202, the steam forms an irregular turbulence before entering the evaporator 1. When the pressure inside the evaporator 1 is high, the piston plate 302 will squeeze the slow-rebound elastic element 301, thereby reducing the pressure inside the evaporator 1 and making the evaporator 1 body have stronger pressure resistance.
