Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and in particular to an energy-saving heat exchanger for a steam heating system. Background Technology

[0002] The working principle of energy-saving heat exchangers in steam heating systems mainly utilizes the latent heat of steam for heat exchange. The latent heat released by steam is much greater than the sensible heat of media such as hot water or oil. This latent heat can be released instantaneously and transferred to the heated medium through the heat exchange surface, thereby achieving efficient heat exchange.

[0003] According to the search, the Chinese patent "A Steam Heat Exchanger for Easy Disassembly and Cleaning" authorized announcement number "CN222279462U" uses a pull handle, a first installation component, a connecting column, a first locking block, a limiting block and a spring to enable the steam heat exchanger body to be installed in a quick-release plate, making the assembly of the steam heat exchanger more convenient.

[0004] In the aforementioned application, the steam heat exchanger body will vibrate during heat exchange, which can easily cause the spring to contract. This can lead to the first locking block becoming loose within the first mounting assembly, resulting in unstable installation of the heat exchanger body and the quick-release plate, thereby affecting the energy-saving heat exchange effect of the heat exchanger.

[0005] Therefore, an energy-saving heat exchanger for a steam heating system is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an energy-saving heat exchanger for a steam heating system to solve the above-mentioned problems, thereby improving the problem of unstable installation of the heat exchanger body and the quick-release plate.

[0007] This utility model achieves the above-mentioned objective through the following technical solution: an energy-saving heat exchanger for a steam heating system, comprising: a heat exchanger shell, with sealing frames on both sides of the heat exchanger shell; and an installation mechanism, the installation mechanism including several insert rods fixedly connected to one side of the sealing frames, the surfaces of the insert rods engaging with the inner wall of the heat exchanger shell, several locking blocks slidably connected to the inner wall of the heat exchanger shell, two limiting frames slidably connected to the inner wall of the heat exchanger shell, the surfaces of the limiting frames engaging with the inner walls of the locking blocks, and a bolt threaded to the front end of the heat exchanger shell, the surface of the bolt rotatably connected to a stop, the surface of the stop engaging with the inner wall of the limiting frames. Through the limiting frames, bolts, and stop, the locking blocks are stably engaged within the insert rods, thereby achieving stable installation of the sealing frames on one side of the heat exchanger shell, thus ensuring the energy-saving heat exchange effect of the heat exchanger.

[0008] Preferably, the inner wall of the heat exchanger shell is slidably connected to a stop rod, the surface of the bolt is engaged with a groove, and the surface of the stop rod is engaged with the inner wall of the groove.

[0009] Preferably, one end of the abutting rod is fixedly connected with an elastic sheet, and the other end of the elastic sheet is fixedly connected to the inner wall of the heat exchanger shell.

[0010] Preferably, the end of the clamping block is fixedly connected with a spring, and the other end of the spring is fixedly connected to the inner wall of the heat exchanger shell.

[0011] Preferably, one end of the abutting rod is bent into an arc shape, and one end of the surface of the inserting rod is in a flat top cone shape.

[0012] Preferably, the end of the clamping block is fixedly connected with a pull rope, and the top end of the pull rope is fixedly connected to the end of the limiting frame. Through the limiting frame and the pull rope, the clamping block is pulled away from the inserting rod, thereby releasing the locking of the blocking frame, and the heat exchanger shell and the blocking frame are simple to disassemble.

[0013] Preferably, the rear end of the abutting frame is fixedly connected with a sliding rod, and the surface of the sliding rod is slidingly connected to the inner wall of the heat exchanger shell. Through the sliding rod, the abutting frame in movement is limited, and deviation of the abutting frame in movement is avoided.

[0014] The beneficial effects of the present application are as follows:

[0015] Through the limiting frame, the bolt and the abutting frame, the clamping block is stably clamped in the inserting rod, thereby realizing stable installation of the blocking frame on one side of the heat exchanger shell. Compared with the unstable installation of the existing heat exchanger body and quick disassembly plate, the present application locks the blocking frame on one side of the heat exchanger shell, thereby ensuring the energy-saving heat exchange effect of the heat exchanger.

[0016] Through the elastic sheet and the abutting rod, the bolt is locked, the bolt is stably threaded in the heat exchanger shell, thereby ensuring the stability of the blocking frame installed on one side of the heat exchanger shell, and improving the energy-saving heat exchange effect of the heat exchanger.

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

Figures 1-4 The heat exchanger shell 1 is internally provided with heat exchange copper pipes. A water inlet pipeline is flange-connected to one side of one of the blocking frames 2, a water outlet pipeline is flange-connected to one side of the other blocking frame 2, a steam inlet pipeline is flange-connected to one of the heat exchange copper pipes on the heat exchanger shell 1, and a steam outlet pipeline is flange-connected to the other heat exchange copper pipe on the heat exchanger shell 1.

[0024] When heat exchange is needed, a delivery pump delivers cold water into the heat exchanger shell 1 through the water inlet pipeline and one of the blocking frames 2, high-temperature and high-pressure steam in a heating system such as a boiler enters one of the heat exchange copper pipes on the heat exchanger through the steam inlet pipeline, the cold water contacts the heat exchange copper pipe, the steam is gradually condensed into water in heat transfer, a large amount of latent heat is released, heat exchange is performed, and the condensed water is discharged from the heat exchanger through the other heat exchange copper pipe and the steam outlet pipeline, so as to prevent accumulated water from affecting the heat exchange efficiency. The cold water in the heat exchanger shell 1 becomes hot water after heat exchange, the delivery pump delivers the hot water to a designated location through the other blocking frame 2 and the water outlet pipeline, and the hot water is used subsequently.

[0025] In the specific implementation, as shown in the figure, an energy-saving heat exchanger of a steam heating system comprises a heat exchanger shell 1, both sides of the heat exchanger shell 1 are provided with blocking frames 2, a mounting mechanism 3 comprises plug rods 31 fixedly connected to one side of the blocking frames 2, the surfaces of the plug rods 31 are clamped to the inner walls of the heat exchanger shell 1, the inner walls of the heat exchanger shell 1 are slidably connected with clamping blocks 32, the inner walls of the heat exchanger shell 1 are slidably connected with limiting frames 34, the surfaces of the limiting frames 34 are clamped to the inner walls of the clamping blocks 32, the front end of the heat exchanger shell 1 is threadedly connected with a bolt 35, the surface of the bolt 35 is rotatably connected with an abutment frame 36, and the surface of the abutment frame 36 is clamped to the inner wall of the limiting frame 34.

[0026] Figure 4 ​As shown, the inner wall of the heat exchanger shell 1 is slidingly connected with the abutting rod 38, the surface of the bolt 35 is connected with the groove 37, the surface of the abutting rod 38 is connected with the inner wall of the groove 37, one end of the abutting rod 38 is fixedly connected with the elastic sheet 39, the other end of the elastic sheet 39 is fixedly connected with the inner wall of the heat exchanger shell 1, one end of the abutting rod 38 is curved into an arc shape, and the surface of the inserting rod 31 is in the shape of a flat top cone.

[0027] As shown in the figure, Figure 3 the end of the clamping block 32 is fixedly connected with the spring 33, and the other end of the spring 33 is fixedly connected with the inner wall of the heat exchanger shell 1. The spring 33 and the elastic sheet 39 are both heat-resistant alloy steel components.

[0028] As shown in the figure, Figure 3 the end of the clamping block 32 is fixedly connected with the pull rope 310, and the top end of the pull rope 310 is fixedly connected with the end of the limiting frame 34. The pull rope 310 is a component made of aramid fiber.

[0029] When the inner wall of the heat exchanger shell 1 needs to be cleaned, the bolt 35 is twisted forcefully. Because one end of the abutting rod 38 is curved into an arc shape, the bolt 35 rotates and makes the abutting rod 38 fall out of the groove 37. At this time, the bolt 35 continues to rotate in the heat exchanger shell 1 and moves away from the limiting frame 34, so that the bolt 35 drives the abutting frame 36 away from the limiting frame 34. At this time, the two limiting frames 34 are pushed away from each other, the limiting frame 34 is moved to pull the pull rope 310, the pull rope 310 is moved to drive the clamping block 32 away from the inserting rod 31, thereby releasing the fixation of the blocking frame 2 on the heat exchanger shell 1. At this time, the blocking frame 2 is pulled to make one side of the heat exchanger shell 1 open, so that the heat exchanger shell 1 can be cleaned, thereby ensuring the energy-saving heat exchange effect in the heat exchanger shell 1.

[0030] After cleaning, the inserting rod 31 on the blocking frame 2 is inserted into the heat exchanger shell 1, and the two limiting frames 34 are loosened. At this time, the elastic force of the spring 33 pushes the clamping block 32 to move and be connected to the inserting rod 31. The bolt 35 is rotated, and the bolt 35 advances in the heat exchanger shell 1 during rotation. The bolt 35 moves to drive the abutting frame 36 to be connected to the limiting frame 34. The elastic force of the elastic sheet 39 pushes the abutting rod 38 to move and be connected to the groove 37, thereby locking the bolt 35, stably connecting the clamping block 32 to the inserting rod 31, and stably installing the blocking frame 2 on one side of the heat exchanger shell 1.

[0031] As shown in the figure, Figure 4 the rear end of the abutting frame 36 is fixedly connected with the sliding rod 311, and the surface of the sliding rod 311 is slidingly connected with the inner wall of the heat exchanger shell 1.

[0032] The utility model discloses when using, the plug -in pole 31 on the plugging frame 2 inserts into the heat exchanger shell 1, and two limit frames 34 are loose, the elastic force of spring 33 pushes the clamping block 32 to move and is clamped into the plug -in pole 31, rotates the bolt 35, makes it advance in the heat exchanger shell 1 rotation and drives the abutment 36 to move and is clamped into the limit frame 34, the elastic force of the spring leaf 39 pushes the abutter 38 to move and is clamped into the recess 37, and then the bolt 35 is locked, makes the clamping block 32 steady and is clamped into the plug -in pole 31, and then makes the plugging frame 2 steady and installs in the heat exchanger shell 1 one side.
