Description

Technical Field

[0001] This utility model relates to the field of sandblasting pipe technology, and more specifically, to a wear-resistant sandblasting pipe device. Background Technology

[0002] When unloading pressure vessels transported by tank trucks containing granular sand, sand needs to be conveyed and discharged through sandblasting pipes. Due to the high-efficiency flow of granular sand over a long period of time, the joints of the sandblasting pipes will wear down. Under normal use, severe wear will occur after unloading every 20,000 tons of alumina sand. Therefore, it is necessary to replace the high-efficiency wear-resistant sandblasting pipes frequently.

[0003] Existing sandblasting hose devices lack sufficient wear resistance and have a lack of stable and reliable wear-resistant structures at the inlet and outlet joints. The durability and practicality of these hoses need improvement. Furthermore, a utility model patent with publication number CN209960029U discloses a high-wear-resistant sandblasting hose, comprising a hose body, a rubber sleeve bonded to the outer surface of the hose body, a second silicone sleeve bonded to the outer surface of the rubber sleeve, a retaining ring fitted onto the outer surface of the second silicone sleeve, support rods fixed to the left and right sides of the retaining ring by bolts, a crossbar inserted into the top of the support rod, a circular hole on the outer surface of the retaining ring for inserting a rubber rod, a first silicone sleeve fitted onto the outside of the retaining ring, a vertical rod on the outer surface of the first silicone sleeve, a third silicone sleeve fitted onto the vertical rod, a threaded hole at the top of the vertical rod, and through holes on the surface of the third silicone sleeve and at positions corresponding to the vertical rod. The inner side of the third silicone sleeve is bonded to the outer surface of the first silicone sleeve. However, this design lacks a stable and reliable wear-resistant structure at the inlet and outlet joints, further compromising the durability and practicality of the sandblasting hose. Utility Model Content

[0004] To overcome the problems of the lack of stable and reliable wear-resistant structures at the inlet and outlet joints of sandblasting pipes in existing technologies, and the need to improve the durability and practicality of sandblasting pipes, this utility model provides a wear-resistant sandblasting pipe device, including a sandblasting pipe and an extended connecting pipe.

The extension pipe is matched with the discharge pipe of the powder and sand tanker. A wear-resistant inner tube is provided on the inner wall of the sandblasting pipe, and wear-resistant protrusions are provided on the wear-resistant inner tube.

[0005] Connecting the sandblasting pipe device to the discharge pipe of the pulverized sand tanker allows the joint of the sandblasting pipe to extend into the interior of the discharge pipe by extending the connecting pipe. This increases the thickness of the pipe joint and enhances wear resistance. At the same time, the sandblasting pipe itself is equipped with a wear-resistant inner tube, which can further improve wear resistance and extend the service life of the pipe.

[0006] Preferably, the sandblasting pipe is provided with connecting flanges at both ends, and wear-resistant gaskets are fixedly installed on the surface of the connecting flanges.

[0007] Preferably, the outer surface of the sandblasting pipe is surrounded by a spiral reinforcing strip, and a reinforcing plate is also provided on the reinforcing strip.

[0008] The spiral reinforcing strips installed on the outer surface of the sandblasting pipe can improve the pipe's strength and enhance its practicality. At the same time, the sandblasting pipe has a pressure-bearing layer inside, which can greatly improve the pipe's pressure resistance and make the pipe less susceptible to damage and breakage from sand and gravel impacts.

[0009] Preferably, the outer diameter of both the extended connecting pipe and the extension pipe is smaller than the inner diameter of the sandblasting pipe, and a fixing groove is provided at the connection between the extended connecting pipe and the extension pipe.

[0010] Preferably, the outer surfaces of the extended connecting pipe and the extension pipe are provided with a wear-resistant coating.

[0011] The extended connecting pipe has a detachable extension pipe at its front end, which is used as a pipe joint to connect to the discharge pipe. The surfaces of the extended connecting pipe and the extension pipe are also coated with a wear-resistant coating to improve wear resistance. Furthermore, the length of the extension pipe can be adjusted and replaced according to the length of the discharge pipe.

[0012] Preferably, the sandblasting pipe has a first pressure-bearing layer and a second pressure-bearing layer that are nested together. Both the first and second pressure-bearing layers are silicone tubes, and a plurality of pressure-bearing reinforcing plates are evenly distributed on the surface of the silicone tubes.

[0013] Preferably, the inner wall of the wear-resistant inner tube has a number of circular wear-resistant protrusions evenly distributed.

[0014] Preferably, the connecting flange is provided with a plurality of connecting holes, and a wear-resistant layer is provided on the inner side of each connecting hole.

[0015] Preferably, the body material of the sandblasting pipe is a wear-resistant rubber pipe.

[0016] Preferably, the outer surface of the sandblasting pipe is provided with a wear-resistant sleeve.

[0017] By incorporating wear-resistant sleeves, the wear resistance of the outer surface of the sandblasting pipe can be improved, thus enhancing its durability.

[0018] Beneficial effects:

[0019] The beneficial effects of adopting the technical solution of this utility model are as follows:

[0020] (1) Connecting the sandblasting pipe device to the discharge pipe of the powder tanker can extend the joint of the sandblasting pipe into the discharge pipe under the effect of the extended connecting pipe, thereby increasing the thickness of the pipe connection and increasing the wear resistance.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0030] This embodiment connects the sandblasting pipe device to the discharge pipe of the pulverized sand tanker. By extending the connecting pipe, the joint of the sandblasting pipe can extend into the interior of the discharge pipe, thereby increasing the thickness of the pipe joint and enhancing wear resistance. Simultaneously, the sandblasting pipe itself has a wear-resistant inner tube, further improving wear resistance and extending the pipe's service life. The specific implementation method is as follows:

[0031] like Figures 1 to 4 As shown, a wear-resistant sandblasting pipe device includes a sandblasting pipe 1 and an extended connecting pipe 5. One end of the sandblasting pipe 1 is provided with the extended connecting pipe 5, and an extension pipe 6 is detachably installed on the extended connecting pipe 5. The extension pipe 6 is matched with the discharge pipe of a pulverized sand tanker. The inner wall of the sandblasting pipe 1 is provided with a wear-resistant inner tube 10, and the wear-resistant inner tube 10 is provided with wear-resistant protrusions 11. Connecting the sandblasting pipe device to the discharge pipe of the pulverized sand tanker allows the joint of the sandblasting pipe to extend into the interior of the discharge pipe under the action of the extended connecting pipe 5, thereby increasing the thickness of the pipe joint and increasing wear resistance. Simultaneously, the wear-resistant inner tube 10 inside the sandblasting pipe 1 further improves wear resistance and extends the service life of the pipe.

[0032] The sandblasting pipe 1 is provided with connecting flanges 2 at both ends, and wear-resistant gaskets 4 are fixedly installed on the surface of the connecting flanges 2. The connecting flanges 2 facilitate the connection and fixation of the sandblasting pipe 1, and the wear-resistant gaskets 4 improve the wear resistance of the connecting flanges 2.

[0033] The outer surface of the sandblasting pipe 1 is surrounded by a spiral reinforcing strip 3, and a reinforcing plate is also provided on the reinforcing strip 3. The spiral reinforcing strip 3 on the outer surface of the sandblasting pipe can improve the strength of the pipe itself and enhance its practicality.

[0034] The outer diameters of both the extended connecting pipe 5 and the extension pipe 6 are smaller than the inner diameter of the sandblasting pipe 1. A fixing groove is provided at the connection between the extended connecting pipe 5 and the extension pipe 6. The extended connecting pipe 5 and the extension pipe 6 are combined to form a pipe joint that connects to the discharge pipe. The front end of the extended connecting pipe 5 is provided with a detachable extension pipe 6, and the length of the extension pipe can be adjusted and replaced according to the length of the discharge pipe.

[0035] The outer surfaces of the extended connecting pipe 5 and the extension pipe 6 are provided with a wear-resistant coating 14. The wear-resistant coating 14 is provided on the surfaces of the extended connecting pipe 5 and the extension pipe 6 to improve wear resistance. The wear-resistant coating 14 is made of ceramic wear-resistant material.

[0036] The sandblasting pipe 1 has an internally connected first pressure-bearing layer 7 and second pressure-bearing layer 8, both of which are silicone tubes, and the surface of the silicone tubes is evenly distributed with several pressure-bearing reinforcing plates 9. The internal structure of the sandblasting pipe with the first pressure-bearing layer 7 and the second pressure-bearing layer 8 can significantly improve the pressure resistance of the pipe, making the pipe less susceptible to damage and breakage from sand and gravel impacts.

[0037] The inner wall of the wear-resistant inner tube 10 has several circular wear-resistant protrusions 11 evenly distributed.

[0038] The connecting flange 2 is provided with several connecting holes 13, and each connecting hole 13 has a wear-resistant layer on its inner side. The connecting holes 13 facilitate a tight connection of the pipes, and the wear-resistant layer improves the durability of the connecting holes 13.

[0039] The body of the sandblasting pipe 1 is made of wear-resistant rubber.

[0040] The outer surface of the sandblasting pipe 1 is provided with a wear-resistant sleeve 12. By providing the wear-resistant sleeve 12, the wear resistance of the outer surface of the sandblasting pipe 1 can be improved, thereby increasing its durability.

[0041] Working Principle: The sandblasting pipe device is connected to the discharge pipe of the powder sand tanker. With the help of the extended connecting pipe, the joint of the sandblasting pipe can extend into the interior of the discharge pipe, thereby increasing the thickness of the pipe joint and enhancing wear resistance. At the same time, the sandblasting pipe itself is equipped with a wear-resistant inner tube, which can further improve wear resistance and extend the service life of the pipe. The spiral reinforcing strip on the outer surface of the sandblasting pipe can improve the strength of the pipe itself and enhance its practicality. In addition, the sandblasting pipe is equipped with a pressure-bearing layer inside, which can significantly improve the pressure resistance of the pipe, making the pipe less susceptible to damage and breakage from sand and gravel impacts. The front end of the extended connecting pipe is equipped with a detachable extension pipe, which is used as a pipe joint to connect to the discharge pipe. The surfaces of the extended connecting pipe and the extension pipe are also equipped with a wear-resistant coating to improve wear resistance. Furthermore, the length of the extension pipe can be adjusted and replaced according to the length of the discharge pipe.
