Description

Technical Field

[0001] The utility model belongs to the technical field of gas transportation and compression, and specifically relates to a high-concentration hydrogen chloride gas compressor. Background Art

[0002] Compressed air has a wide range of applications. It is a device without moving parts and can generate a high ventilation volume. It uses compressed air or steam as power. Therefore, the blower is suitable for occasions with dangerous gases. With the rapid development of the national economy, all walks of life have different requirements for blowers. The blowers for transporting and compressing gases with high concentration and strong corrosiveness in special industries have been troubled by two problems for a long time. For the blowers made of traditional anti-corrosion materials, strength and rigidity are short boards, such as fiberglass blowers, etc.; for the blowers made of anti-corrosion materials such as stainless steel, there are limitations on the concentration of acid or alkaline corrosion, and the manufacturing cost is relatively high. For this reason, this application proposes a high-concentration hydrogen chloride gas compressor. Content of the Utility Model

[0003] To solve the problems raised in the above background art, the utility model provides the following technical solution: A high-concentration hydrogen chloride gas compressor includes a bottom plate, on which a casing is fixedly installed. A bearing box is fixedly installed on the bottom plate and on the right side of the casing. A semi-open three-dimensional flow impeller is arranged inside the casing. A rotatable main shaft is inserted through the bearing box from left to right. The left end of the main shaft extends into the casing and is connected to the semi-open three-dimensional flow impeller. A driving speed increasing box is installed at the right end of the main shaft. Anti-corrosion glue layers are sprayed on the inner surface of the casing and the outer surface of the semi-open three-dimensional flow impeller. There is a spacing between the inner wall of the casing and the outer wall of the semi-open three-dimensional flow impeller.

[0004] Further, through holes are opened at both ends of the bearing box, and sliding bearings are fixedly installed in the through holes at both ends of the bearing box. The main shaft is installed on the two sliding bearings.

[0005] Further, an opening is opened on the right side of the casing, and a shaft end seal is fixedly installed in the opening. The left end of the main shaft penetrates through the shaft end seal and is connected to the semi-open three-dimensional flow impeller.

[0006] Further, the semi-open three-dimensional flow impeller and the main shaft are welded into one body.

[0007] Further, a toothed coupling is arranged between the right end of the main shaft and the driving speed increasing box.

[0008] Further, the anti-corrosion glue layers on the inner surface of the casing and the outer surface of the semi-open three-dimensional flow impeller can isolate hydrogen chloride gas.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] By driving the speed increasing gearbox to rotate, the semi-open three-way flow impeller on the main shaft is driven to work. The anti-corrosion adhesive layer effectively isolates the corrosion of the high-concentration hydrogen chloride gas on the semi-open three-way flow impeller and the casing. The shaft end seal prevents the leakage of hydrogen chloride, realizing the transportation and compression of high-concentration hydrogen chloride gas. Therefore, it has the characteristics of short production cycle, low manufacturing cost, high safety and reliability, compact structure, high efficiency, and can operate safely and stably for a long time.

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

[0016] It is composed of Figure 1-2 As shown, the present invention includes a bottom plate 3, on which a casing 2 is fixedly installed. A bearing box 5 is fixedly installed on the bottom plate 3 and on the right side of the casing 2. A semi-open three-way flow impeller 1 is arranged in the casing 2. A rotatable main shaft 6 is inserted through the bearing box 5 from left to right. The left end of the main shaft 6 extends into the casing 2 and is connected to the semi-open three-way flow impeller 1. A driving speed increasing gearbox 9 is installed at the right end of the main shaft 6. The inner surface of the casing 2 and the outer surface of the semi-open three-way flow impeller 1 are both sprayed with an anti-corrosion adhesive layer 10. There is a gap between the inner wall of the casing 2 and the outer wall of the semi-open three-way flow impeller 1.

[0017] As Figure 1 shown, through holes are provided at both ends of the bearing box 5, and sliding bearings 7 are fixedly installed in the through holes at both ends of the bearing box 5. The main shaft 6 is installed on the two sliding bearings 7, and the connection between the main shaft 6 and the bearing box 5 is completed through the sliding bearings 7.

[0018] As shown Figure 1 in FIG., an opening is provided on the right side of the casing 2, and a shaft end seal 4 is fixedly installed in the opening. The left end of the main shaft 6 penetrates through the shaft end seal 4 and is connected to the semi-open three-dimensional flow impeller 1. Through the shaft end seal 4, leakage of hydrogen chloride can be prevented, thereby realizing the transportation and compression of high-concentration hydrogen chloride gas.

[0019] As shown Figure 1 in FIG., the semi-open three-dimensional flow impeller 1 and the main shaft 6 are welded into one body, increasing the stability of the connection between the semi-open three-dimensional flow impeller 1 and the casing 2.

[0020] As shown Figure 1 in FIG., a toothed coupling 8 is provided between the right end of the main shaft 6 and the drive speed increasing box 9. Through the toothed coupling 8, the transmission connection between the right end of the main shaft 6 and the drive speed increasing box 9 can be realized.

[0021] As shown Figure 1 and Figure 2 in FIG., the anti-corrosion glue layer 10 on the inner surface of the casing 2 and the outer surface of the semi-open three-dimensional flow impeller 1 can isolate hydrogen chloride gas. The anti-corrosion glue layer 10 can effectively isolate the corrosion of the high-concentration hydrogen chloride gas on the outer surface of the semi-open three-dimensional flow impeller 1 and the inner surface of the casing 2, thereby playing a good protective role on the outer surface of the semi-open three-dimensional flow impeller 1 and the inner surface of the casing 2.

[0022] Working principle: The prime mover drives the semi-open three-dimensional flow impeller 1 on the main shaft 6 to work by rotating the drive speed increasing box 9. The anti-corrosion glue layer 10 effectively isolates the corrosion of the high-concentration hydrogen chloride gas on the semi-open three-dimensional flow impeller 1 and the casing 2, and the shaft end seal 4 prevents the leakage of hydrogen chloride, realizing the transportation and compression of high-concentration hydrogen chloride gas.
