It is a device widely demanded in sugar-making, pharmaceutical, chemical, food, salt-making, monosodium glutamate, milk, and fermentation factories. The water jet vacuum pump uses water flow with a certain pressure to spray out symmetrically and uniformly at a certain side slope and converge at a focus. Due to the relatively high velocity of the jet water flow, a negative pressure is formed around, causing a vacuum in the chamber. In addition, since the secondary steam is in direct contact with the jet water flow for heat exchange, when using a water jet vacuum pump, a corresponding heat exchange component will be installed to exchange and adjust cold water and hot water to cooperate with the jet work of the water jet vacuum pump.

[0003] The existing heat exchange components for water jet vacuum pumps generally use flange plates for installation with connecting pipes. During the installation or replacement of the pipes of the heat exchange component, the staff needs to align the pipe orifice with the interface, and then hold the pipe by hand to ensure that the flange plates can be continuously aligned until the first few screws are installed in the screw holes of the flange plates before the support for the pipe can be stopped.

Apparently, the described embodiments are only a part rather than all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] The following will further elaborate on the present utility model Figures 1-6 in further detail.

[0029] Embodiment 1

[0030] Please refer to Figures 1-6 , this embodiment provides a technical solution: a heat exchange component for a water jet vacuum pump, including a connecting pipe 1, a first fixing member 2 and a second fixing member 3. A graphite heat exchanger 4 is arranged below the connecting pipe 1. The top end of the graphite heat exchanger 4 is installed and connected to the end of the connecting pipe 1 through a flange plate. At the same time, the graphite heat exchanger 4 is connected to the water jet vacuum pump through another group of pipes. Water is conveyed into the interior of the graphite heat exchanger 4 by using the connecting pipe 1 and another group of pipes to achieve the purpose of adjusting the water temperature. It is used to cooperate with the jet work of the water jet vacuum pump. A water pump 5 is arranged outside the graphite heat exchanger 4. The end of the water pump 5 is connected to one end of the connecting pipe 1 away from the graphite heat exchanger 4 for pumping and transporting liquid back and forth. The bottom of the graphite heat exchanger 4 is threadedly connected with a support bottom plate. The water pump 5 is threadedly connected to the surface of the support bottom plate and is externally connected to a power supply. There are two groups of water pumps 5, and both are interconnected with the interior of the graphite heat exchanger 4 through the connecting pipe 1, mainly for conveying water.

[0031] Embodiment 2

[0032] Please refer to Figures 1-6 , the first fixing member 2 includes an arc-shaped mounting plate 201 arranged outside the connecting pipe 1. The structural shape of the arc-shaped mounting plate 201 is semi-circular. The size and shape of the arc-shaped mounting plate 201 are adapted to the flange connection part between the connecting pipe 1 and the graphite heat exchanger 4. One end of the arc-shaped mounting plate 201 close to the arc-shaped insertion plate 301 is threadedly connected with a first connecting block 202. When the arc-shaped mounting plate 201 and the arc-shaped insertion plate 301 wrap the connection part between the connecting pipe 1 and the graphite heat exchanger 4, the arc-shaped mounting plate 201 can push the first connecting block 202 to contact the end of the arc-shaped insertion plate 301. A square notch 203 is opened inside the first connecting block 202.

[0033] Embodiment 3

[0034] Please refer to Figures 1-6, the second fixing member 3 is arranged on the outer side of the connecting pipe 1, and a part of the second fixing member 3 is hinged to the first fixing member 2. The second fixing member 3 and the first fixing member 2 wrap the flange connection part of the connecting pipe 1 and the graphite heat exchanger 4, and can fix the connection part of the aligned connecting pipe 1 and the graphite heat exchanger 4, facilitating the staff to install screws, thereby fixing the flange connection part of the connecting pipe 1 and the graphite heat exchanger 4, which is convenient for the staff to install. The second fixing member 3 includes an arc-shaped insertion plate 301 arranged on the outer side of the connecting pipe 1. The structural shape of the arc-shaped insertion plate 301 is semi-circular. Installation holes are opened inside the arc-shaped insertion plate 301, and their quantity and positions correspond to the threaded holes inside the flange plate, facilitating the staff to install screws into the threaded holes. One end of the arc-shaped insertion plate 301 is threadedly connected with a second connecting block 302, and a fixing block 303 is threadedly connected to the side of the second connecting block 302 away from the arc-shaped insertion plate 301. Moving grooves 304 are opened on the top surface and the bottom surface of the fixing block 303. A telescopic rod 305 is slidably connected to the inner side wall of the moving groove 304. A clamping block 306 is welded to the end of the telescopic rod 305 away from the moving groove 304. A spring 307 is sleeved around the outer side of the telescopic rod 305. One end of the spring 307 is welded to the outer side wall of the clamping block 306, and the other end of the spring 307 is welded to the inner side wall of the moving groove 304. Therefore, when the arc-shaped insertion plate 301 wraps the flange connection part of the connecting pipe 1 and the graphite heat exchanger 4, by using the telescopic functions of the telescopic rod 305 and the spring 307, the clamping block 306 can be squeezed into the moving groove 304. The arc-shaped insertion plate 301 drives the second connecting block 302 to contact the first connecting block 202. The second connecting block 302 pushes the fixing block 303 to insert into the square notch 203. The fixing block 303 drives the clamping block 306 to move into the square notch 203 until a part of the fixing block 303 and the clamping block 306 are located outside the square notch 203. By using the reset function of the spring 307, the spring 307 pushes the clamping block 306 to move to the initial position, and the clamping block 306 abuts against the outer side wall of the first connecting block 202. Therefore, the purpose of fixing between the end parts of the arc-shaped insertion plate 301 and the arc-shaped mounting plate 201 can be achieved. A sliding block 308 is welded to the outer side wall of the clamping block 306. The sliding block 308 fits with the inner side wall of the moving groove 304. The structural shape of the moving groove 304 is adapted to the clamping block 306 and the sliding block 308. When the clamping block 306 is squeezed into the moving groove 304, the sliding block 308 slides inside the moving groove 304, which can improve the stability of the clamping block 306 when moving up and down. A plug-in groove 204 is opened inside the first connecting block 202. A plug 309 is threadedly connected to the outer side wall of the fixing block 303 close to the first connecting block 202. One end of the plug 309 away from the fixing block 303 inserts into the plug-in groove 204. By using the plugging state of the plug 309 and the plug-in groove 204, the connection state between the second connecting block 302 and the first connecting block 202 can be made more stable.

[0035] Working principle: First, align the end of the connecting pipe 1 with the flange connection of the graphite heat exchanger 4. Then, take out the arc-shaped insertion plate 301 and the arc-shaped mounting plate 201, wrap the arc-shaped insertion plate 301 and the arc-shaped mounting plate 201 around the flange connection, and push the second connecting block 302 closer to the first connecting block 202;

[0036] Secondly, apply an extrusion force to the two groups of clamping blocks 306. The clamping blocks 306 move into the interior of the movable groove 304 under the cooperation of the telescopic functions of the telescopic rods 305 and the springs 307. Then, insert the fixing block 303 into the interior of the square notch 203. The fixing block 303 drives the clamping blocks 306 to move synchronously into the interior of the square notch 203 until a part of the fixing block 303 moves to the outside of the first connecting block 202;

[0037] Finally, the extrusion force applied to the clamping blocks 306 disappears. Driven by the restoring force of the spring 307, the clamping blocks 306 move towards the initial position. Thus, the clamping blocks 306 are clamped with the outside of the first connecting block 202, enabling the connection between the second connecting block 302 and the first connecting block 202, fixing the position of the flange connection between the connecting pipe 1 and the graphite heat exchanger 4, aligning the end of the connecting pipe 1, and eliminating the need for continuous support, facilitating the installation of screws by the staff and finally completing the work.

[0038] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any perspective, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be encompassed by the present utility model.
