Description

Technical Field

[0001] This utility model relates to the field of condenser technology, specifically a distillation condenser. Background Technology

[0002] Distillation, as a highly efficient and widely used separation technology, is a core process in modern chemical industry, petroleum refining, pharmaceuticals, and fine chemicals. Its basic principle is to utilize the differences in volatility of the components in a mixture, achieving high-purity separation through multiple partial vaporization and condensation of the gas and liquid phases on trays or packing materials. According to CN218672710U, a shell-and-tube condenser structure is disclosed. This technology discloses a technical solution including: a shell-and-tube condenser body, screws, and clamping plates. An inlet pipe is embedded on one side of the top of the shell-and-tube condenser body. Support plates are welded to the top of the shell-and-tube condenser body on both sides of the inlet pipe. The two support plates are respectively provided with screw holes. The two screws are respectively engaged with the screw holes of the two support plates. Bearings are embedded on the opposite sides of the two clamping plates. The opposite ends of the two screws are respectively rotatably connected to the two bearings. Fixing blocks are respectively installed on the opposite ends of the two screws. Rubber sleeves are installed on both sides of the bottom of the shell-and-tube condenser body. A liquid outlet pipe is embedded on the bottom of the shell-and-tube condenser body on the opposite side of the two rubber sleeves. This technology has the advantage of "clamping and fixing the pipe connected to the inlet pipe, increasing the stability of the pipe". The required flange connection method relies on operators using tools to tighten or loosen multiple bolts one by one in sequence. In distillation operations that require frequent maintenance, cleaning, or process switching, this cumbersome and time-consuming operation process will directly lead to extended equipment preparation time and become a major bottleneck affecting overall operation and maintenance efficiency. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a distillation condenser that simplifies the tedious operation of tightening multiple bolts one by one in traditional flange connections into a single rotation action, achieving rapid, synchronous, and uniform tightening of the flange, improving the efficiency of pipeline connection operations, and shortening equipment maintenance time.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a distillation condenser, comprising a shell-and-tube condenser for vapor-phase condensation in a distillation column system, wherein the shell-and-tube condenser includes: The main components include a left tube sheet fixed to the left end of the shell, a tube box fixed to the left end of the left tube sheet, inlet and outlet water ports fixed at both the upper and lower ends of the tube box, and flange heads fixed to the outer ends of the inlet and outlet water ports. The connecting assembly includes four circumferentially arranged lugs fixed to the outer edge of the bottom of the flange head. A clamping arm is pivotally connected to the outer end of the lug. A clamp is installed at the bottom of the upper end of the clamping arm. An external threaded sleeve is rotatably installed on the outer wall of the inlet and outlet. An internal threaded ring is threadedly installed on the outer wall of the external threaded sleeve. Four circumferentially arranged connecting rods are pivotally connected to the outer wall of the internal threaded ring, and the upper end of the connecting rods is pivotally connected to the lower end of the clamping arm.

[0005] Preferably, the connecting assembly further includes an upper fixing ring fixed to the outer wall of the inlet and outlet and located above the external threaded sleeve, a lower fixing ring fixed to the outer wall of the inlet and outlet and located below the external threaded sleeve, and a limit frame fixed to the outer wall of the upper fixing ring and restricting the rotation of the internal threaded sleeve.

[0006] Preferably, the connecting assembly further includes a handwheel fixed to the lower end of the outer wall of the external threaded sleeve.

[0007] Preferably, the connecting assembly further includes an internal hex bolt threaded onto the upper end of the clamping arm for securing the clamp.

[0008] Preferably, the main body component further includes a left end cap fixed to the left end of the tube box, a partition plate fixed in the middle inside the tube box to separate the tube box from the inside, a right tube plate fixed to the right end of the shell, a right end cap fixed to the right end of the right tube plate, a number of heat exchange tubes fixed between the left tube plate and the right tube plate, and a number of baffles fixed inside the shell to fix the heat exchange tubes.

[0009] Preferably, the main body component further includes an air inlet fixed to the upper right side of the housing and a drain outlet fixed to the lower left side of the housing.

[0010] Beneficial effects This invention provides a distillation condenser. Compared with the prior art, it has the following advantages: 1. By rotating the handwheel to drive the external threaded sleeve to rotate, the internal threaded ring sleeve that mates with the internal thread is forced to generate axial displacement due to the constraint of the positioning frame. Then, through four circumferentially distributed connecting rods, four sets of clamping arms are driven to pivot synchronously around the lugs. Finally, the chucks installed at the top of the clamping arms clamp or loosen the flange heads on other equipment. This simplifies the tedious operation of tightening multiple bolts one by one in traditional flange connections to a single rotation action, realizing fast, synchronous, and uniform locking of flanges, improving the efficiency of pipeline connection operations and shortening equipment maintenance time.

[0011] 2. The operator does not need any special tools. By simply rotating the handwheel, the operator can easily drive the external threaded sleeve to rotate around the axis of the inlet and outlet through the increased rotational lever arm. Furthermore, the detachable chuck has a certain degree of positional adaptability, which can compensate for the gaps caused by manufacturing tolerances or long-term wear, and it is easy to replace the chuck separately after it wears out.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0015] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a distillation condenser, including a shell-and-tube condenser 1 for vapor-phase condensation in a distillation column system, wherein the shell-and-tube condenser 1 includes: The main component 11 includes a left tube plate 112 fixed to the left end of the housing 111, a tube box 113 fixed to the left end of the left tube plate 112, and inlet and outlet ports 114 fixed at both the upper and lower ends of the tube box 113. A flange head 115 is fixed to the outer end of the inlet and outlet ports 114. The connecting assembly 12 includes four circumferentially arranged lugs 121 fixed to the outer edge of the bottom of the flange head 115. The outer ends of the lugs 121 are pivotally connected to clamping arms 122. The upper bottom of the clamping arms 122 is equipped with a chuck 123. The outer wall of the inlet / outlet 114 is fitted with an externally threaded sleeve 124. The outer wall of the externally threaded sleeve 124 is fitted with an internally threaded ring sleeve 125. The outer wall of the internally threaded ring sleeve 125 is pivotally connected to four circumferentially arranged connecting rods 126, and the upper ends of the connecting rods 126 are pivotally connected to the lower ends of the clamping arms 122.

[0016] In this embodiment, the external threaded sleeve 124 is driven to rotate by turning the handwheel 1210. The internal threaded ring sleeve 125, which mates with the internal thread, is forced to generate axial displacement due to the constraint of the limiting frame 129. Then, the four circumferentially distributed connecting rods 126 push the four sets of clamping arms 122 to pivot synchronously around the lug 121. Finally, the chuck 123 installed at the top of the clamping arm 122 clamps or loosens the flange head on other equipment. This simplifies the tedious operation of tightening multiple bolts one by one in traditional flange connection to a single rotation action, realizing fast, synchronous and uniform locking of the flange, improving the operation efficiency of pipeline connection and shortening equipment maintenance time.

[0017] Specifically, the connecting assembly 12 also includes an upper fixing ring 127 fixed to the outer wall of the inlet / outlet 114 and located above the external threaded sleeve 124, a lower fixing ring 128 fixed to the outer wall of the inlet / outlet 114 and located below the external threaded sleeve 124, and a limit bracket 129 fixed to the outer wall of the upper fixing ring 127 and restricting the rotation of the internal threaded ring sleeve 125.

[0018] In this embodiment, the upper fixing ring 127 and the lower fixing ring 128 together form the axial positioning support of the external threaded sleeve 124 on the outer wall of the inlet / outlet 114, so that it can rotate smoothly without axial movement; one end of the internal threaded sleeve 125 is embedded in the limiting frame 129, which restricts the circumferential rotational freedom of the internal threaded sleeve 125.

[0019] Specifically, the connecting assembly 12 also includes a handwheel 1210 fixed to the lower end of the outer wall of the external threaded sleeve 124.

[0020] In this embodiment, the operator does not need to use any special tools. By simply rotating the handwheel 1210, the operator can easily drive the external threaded sleeve 124 to rotate around the axis of the inlet / outlet 114 through the increased rotational lever arm.

[0021] Specifically, the connecting assembly 12 also includes an internal hex bolt 1211 threaded onto the upper end of the clamp arm 122 and used to secure the chuck 123.

[0022] In this embodiment, the detachable chuck 123 has a certain positional adaptability, which can compensate for the gap caused by manufacturing tolerances or long-term wear, and facilitates individual replacement after the chuck 123 wears out.

[0023] Specifically, the main body component 11 also includes a left end cap 116 fixed to the left end of the tube box 113, a partition 117 fixed in the middle of the tube box 113 to separate the tube box 113 internally and vertically, a right tube plate 118 fixed to the right end of the shell 111, a right end cap 119 fixed to the right end of the right tube plate 118, a number of heat exchange tubes 1110 fixed between the left tube plate 112 and the right tube plate 118, and a number of baffles 1111 fixed inside the shell 111 to fix the heat exchange tubes 1110.

[0024] Specifically, the main component 11 also includes an air inlet 1112 fixed on the upper right side of the housing 111, and a drain outlet 1113 fixed on the lower left side of the housing 111.

[0025] The working principle and usage process of this utility model are as follows: First, the operator initially aligns the external pipe flange with the flange head 115 at the inlet / outlet 114. Then, the operator holds and rotates the handwheel 1210 fixed to the outer wall of the external threaded sleeve 124. The rotation of the handwheel 1210 causes the external threaded sleeve 124 to rotate together. Through the axial positioning formed by the upper fixing ring 127 and the lower fixing ring 128, the external threaded sleeve 124 can only rotate smoothly without axial movement. At the same time, the internal threaded ring that mates with the external thread... 125, because its circumferential rotational freedom is restricted by the limiting frame 129 fixed to the upper fixed ring 127, converts the rotational motion of the external threaded sleeve 124 into its own precise axial displacement; when the internal threaded sleeve 125 moves downward, it pushes the lower end of the four sets of clamping arms 122 through the four circumferentially distributed connecting rods 126, forcing the clamping arms 122 to pivot synchronously inward around the connection point with the shaft lug 121, and then uniformly and synchronously close through the clamp 123 at the top of the clamping arm 122, thereby locking the flange of the external pipe.
