Description

Technical Field

[0001] This utility model relates to the field of vacuum pump flow guiding technology, specifically to a vacuum pump steam collection and flow guiding device. Background Technology

[0002] The vacuum pump exhaust pipe is led from the indoor vacuum pump to the outside of the outdoor wall. Since some water is sprayed out from the exhaust pipe each time the vacuum pump is started, the water vapor discharged from the exhaust pipe during normal operation of the vacuum pump will quickly condense into water droplets in the northern winter and fall on the roof and ground below the exhaust pipe, causing the side wall paint of the building to peel off and the roof and ground to freeze, endangering the building and personal safety. Summary of the Invention

[0003] To address the aforementioned shortcomings in the existing technology, this utility model provides a vacuum pump steam collection and diversion device to solve the problem that water vapor discharged from the exhaust pipe of the existing vacuum pump easily condenses into water droplets and falls onto the roof and ground below the exhaust pipe during normal operation, causing the side wall plaster of the building to peel off, the roof and ground to freeze, and endangering the safety of the building and people.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A vacuum pump steam collection and guiding device includes an exhaust box with an exhaust pipe fixedly installed on its top surface; two inlet boxes fixedly installed on the same side of the exhaust box, each with an inlet pipe fixedly installed on its top surface; and a guide section fixedly installed on the inner walls of the exhaust box and the two inlet boxes. The bottoms of the two inlet boxes are connected to the exhaust box, and the output port of the inlet pipe faces the top surface of the guide section. The guide section enables the water vapor discharged from the exhaust pipe to condense into water droplets.

[0005] In this way, the large amount of water vapor discharged from the vacuum pump enters the steam inlet box through the steam inlet pipe. The increased space within the steam inlet box buffers the water vapor, consuming its kinetic energy. After entering the steam inlet box, the water vapor comes into contact with the guide section, condensing into water droplets on its surface and falling to the bottom of the steam inlet box. The condensate then enters the exhaust box through the connection, completing the collection of the water vapor discharged from the vacuum pump. During the steam collection process, steam enters the steam inlet box through the steam inlet pipe installed on the top surface of the steam inlet box. Most of the steam comes into contact with the guide section and condenses into water droplets that fall to the bottom surface of the steam inlet box. A small portion of the steam comes into direct contact with the bottom surface of the steam inlet box. Specifically, the steam that initially comes into contact with the bottom surface of the steam inlet box consumes its kinetic energy and is blocked by the guide section again, condensing into water droplets. Only a small portion flows back into the exhaust pipe, condenses on the inner wall of the exhaust pipe, and falls back to the bottom surface of the exhaust box. The steam that subsequently enters the steam inlet box comes into contact with the condensate on the bottom surface of the steam inlet box, cools down rapidly, and also condenses into water droplets. This structure can collect the steam discharged from the vacuum pump, reducing the possibility of steam being discharged to the outside and condensing into water that corrodes the side walls of the building. It also reduces the possibility of the condensate freezing and endangering personal safety.

[0006] Furthermore, the guide section includes multiple guide plates fixedly installed on the inner walls of the exhaust box and the two inlet boxes. The guide plates are generally L-shaped and are divided into a first flange and a second flange. The connection between the first flange and the second flange faces the top surface inside the exhaust box, and the opening between the first flange and the second flange faces the bottom surface inside the exhaust box.

[0007] In this way, after the water vapor discharged from the vacuum pump enters the steam inlet box, it comes into contact with the first and second flanges of the guide vane, and the water vapor begins to condense into water droplets on the surfaces of the first and second flanges. The connection between the first and second flanges faces the top surface inside the exhaust box, which diverts the water vapor entering the steam inlet box, consumes the kinetic energy carried by the water vapor, and makes it easier for the water vapor to condense into water droplets on the surfaces of the first and second flanges. The opening between the first and second flanges faces the bottom surface inside the exhaust box, which blocks the water vapor that directly contacts the bottom surface inside the steam inlet box and rushes back, consumes the kinetic energy carried by the water vapor, and makes it easier for the water vapor to condense into water droplets on the surfaces of the first and second flanges. With this structure, the kinetic energy carried by the water vapor discharged from the vacuum pump can be consumed, increasing the possibility of water vapor condensing into water droplets on the surfaces of the first and second flanges.

[0008] Furthermore, the guide vanes are arranged vertically in three rows, and the three rows of guide vanes are staggered, with the end of the first flange of the upper guide vane directly opposite the second flange of the lower guide vane.

[0009] In this way, after the water vapor initially entering the steam inlet box condenses into water droplets on the surfaces of the first and second flanges, the water vapor entering later can blow the water droplets down to the bottom surface inside the steam inlet box. This structure can consume the kinetic energy carried by the water vapor discharged by the vacuum pump, and at the same time cause the water droplets condensed on the surfaces of the first and second flanges to fall down to the bottom surface inside the steam inlet box, making it easier to collect the condensate in a unified manner later.

[0010] Furthermore, the exhaust pipe and the inlet pipe are reducing pipes, which facilitates the connection between the inlet pipe and the exhaust pipe of the vacuum pump, and at the same time can consume the kinetic energy carried by the water vapor entering the exhaust pipe.

[0011] Furthermore, the end of the exhaust pipe is bent at a 90° angle, which reduces the possibility of water vapor entering the exhaust pipe being discharged from the exhaust pipe, thereby reducing the possibility of water vapor being discharged to the outside and condensing into water that corrodes the side wall of the building.

[0012] Furthermore, a support frame is fixedly installed on the bottom surface of the exhaust box, which can support the flow guiding device and at the same time reserve space for installing the drain pipe.

[0013] Furthermore, a drain pipe is fixedly installed on the bottom surface of the exhaust box, which facilitates the recovery of the condensate collected in the exhaust box. Attached Figure Description

[0015] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of this utility model, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0017] Example: like Figures 1-4As shown, the vacuum pump steam collection and guiding device of this utility model includes an exhaust box 1, on which an exhaust pipe 101 is fixedly installed; two steam inlets 2, which are fixedly installed on the same side of the exhaust box 1, and each of the two steam inlets 2 has a steam inlet pipe 201 fixedly installed on its top surface, with the steam inlet pipe 201 connected to a vacuum pump; and a guiding section 3, which is fixedly installed on the inner wall of the exhaust box 1 and the two steam inlets 2; the bottom of each of the two steam inlets 2 is connected to the exhaust box 1, and the output end of the steam inlet pipe 201 faces the top surface of the guiding section 3, which enables the water vapor discharged from the exhaust pipe 101 to condense into water droplets.

[0018] In this way, a large amount of water vapor discharged from the vacuum pump enters the steam inlet box 2 through the steam inlet pipe 201. The increased space within the steam inlet box 2 buffers the large amount of water vapor, thus consuming its kinetic energy. After entering the steam inlet box 2, the water vapor comes into contact with the guide section 3. The water vapor condenses into water droplets on the surface of the guide section 3 and falls to the bottom of the steam inlet box 2. The condensate then enters the exhaust box 1 through the connection, completing the collection of the water vapor discharged from the vacuum pump. During the steam collection process, steam enters the steam inlet 2 through the steam inlet pipe 201 installed on the top surface of the steam inlet 2. Most of the steam comes into contact with the guide section 3 and condenses into water droplets that fall to the bottom surface of the steam inlet 2. A small portion of the steam comes into direct contact with the bottom surface of the steam inlet 2. Specifically, the steam that initially comes into contact with the bottom surface of the steam inlet 2 is blocked by the guide section 3 again after consuming its kinetic energy and condenses into water droplets. Only a small portion flows back into the exhaust pipe 101, condenses on the inner wall of the exhaust pipe 101, and falls back to the bottom surface of the exhaust box 1. The steam that subsequently enters the steam inlet 2 comes into contact with the condensate on the bottom surface of the steam inlet 2, cools down rapidly, and also condenses into water droplets. With this structure, the steam discharged from the vacuum pump can be collected, reducing the possibility of steam being discharged to the outside and condensing into water that corrodes the side walls of the building. It also reduces the possibility of the condensate freezing and endangering personal safety.

[0019] The flow guide 3 includes multiple flow guide plates 301 fixedly installed on the inner walls of the exhaust box 1 and two inlet boxes 2. The flow guide plate 301 is generally L-shaped and is divided into a first flange 302 and a second flange 303. The connection between the first flange 302 and the second flange 303 faces the inner top surface of the exhaust box 1, and the opening between the first flange 302 and the second flange 303 faces the inner bottom surface of the exhaust box 1.

[0020] In this way, after the water vapor discharged from the vacuum pump enters the steam inlet box 2, it comes into contact with the first flange 302 and the second flange 303 of the guide plate 301, and the water vapor begins to condense into water droplets on the surface of the first flange 302 and the second flange 303. The connection between the first flange 302 and the second flange 303 faces the top surface inside the exhaust box 1, which diverts the water vapor entering the steam inlet box 2, consumes the kinetic energy carried by the water vapor, and makes it easier for the water vapor to condense into water droplets on the surface of the first flange 302 and the second flange 303. The opening between the first flange 302 and the second flange 303 faces the bottom surface inside the exhaust box 1, which blocks the water vapor that directly contacts the bottom surface inside the steam inlet box 2 and rushes back, consumes the kinetic energy carried by the water vapor, and makes it easier for the water vapor to condense into water droplets on the surface of the first flange 302 and the second flange 303. With this structure, the kinetic energy carried by the water vapor discharged from the vacuum pump can be consumed, and the possibility of water vapor condensing into water droplets on the surface of the first flange 302 and the second flange 303 can be increased.

[0021] The deflector 301 is vertically arranged in three rows, and the three rows of deflector 301 are staggered. The end of the first flange 302 of the upper deflector 301 is directly opposite the second flange 303 of the lower deflector 301.

[0022] In this way, after the water vapor initially entering the steam inlet box 2 condenses into water droplets on the surfaces of the first flange 302 and the second flange 303, the water vapor entering later can blow the water droplets down to the bottom surface inside the steam inlet box 2. This structure can consume the kinetic energy carried by the water vapor discharged by the vacuum pump, and at the same time cause the water droplets condensed on the surfaces of the first flange 302 and the second flange 303 to fall down to the bottom surface inside the steam inlet box 2, which is convenient for the subsequent unified collection of condensate.

[0023] The exhaust pipe 101 and the inlet pipe 201 are reducing pipes, which facilitates the connection between the inlet pipe 201 and the exhaust pipe of the vacuum pump, and at the same time can consume the kinetic energy carried by the water vapor entering the exhaust pipe 101.

[0024] The end of the exhaust pipe 101 is bent at a 90° angle, which reduces the possibility of water vapor entering the exhaust pipe 101 being discharged from the exhaust pipe 101, thereby reducing the possibility of water vapor being discharged to the outside and condensing into water that corrodes the side wall of the building.

[0025] A support frame 4 is fixedly installed on the bottom surface of the exhaust box 1, which can support the flow guiding device and at the same time reserve space for installing the drain pipe 102.

[0026] A drain pipe 102 is fixedly installed on the bottom surface of the exhaust box 1, which facilitates the recovery of condensate collected in the exhaust box 1.
