Description

Technical Field

[0001] The utility model relates to the technical field of steam generators, and particularly relates to a vehicle-mounted steam generator. Background Technique

[0002] A steam generator, also called a steam heat source machine (commonly known as a boiler), is a mechanical device that uses the heat energy of fuel or other energy sources to heat water into hot water or steam. The original meaning of "pot" refers to a water container heated on fire, and "furnace" refers to a place where fuel is burned. A boiler includes two major parts: the pot and the furnace. A steam generator is also called an oilfield steam injection boiler and can be divided into two categories: fixed type and vehicle-mounted type. The vehicle-mounted steam generator is convenient to use, can reduce the workload of oilfield surface construction and reduce the heat loss of pipeline transportation.

[0003] After the existing steam generator is used for a long time, the liquid water may have impurity particles after being heated to form water vapor, which affects the steam generation quality. Moreover, if the water is not filtered, it is easy to cause blockage of the steam injection port, reducing the service life of the steam generator. Therefore, for the improvement of the existing steam generator, it is particularly important to design a new type of vehicle-mounted steam generator to solve the above technical defects and improve the practicability of the overall steam generator. Summary of the Utility Model

Multiple groups of filter meshes inside the filter cylinder can filter the water flow, ensuring that the water entering the water storage cavity of the steam boiler can be filtered once, and the steam coming out of the water storage cavity of the steam boiler can be filtered twice, thereby improving the purity of the steam ejected by the steam boiler. At the same time, the injection port of the steam boiler is not prone to blockage, increasing the service life of the steam boiler. And when it is necessary to install the filter cylinder, it can be conveniently installed, and similarly, it can be conveniently disassembled and cleaned to solve the problems raised in the above background technique.

Detailed Embodiment

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0023] A vehicle-mounted steam generator, comprising a trailer main body 1, a steam boiler 2 is arranged on the outer side of the trailer main body 1, a water inlet pipe 3 is arranged on the outer side of the steam boiler 2, a water tank 4 is arranged at one end of the trailer main body 1 far away from the steam boiler 2, the water tank 4 is connected to the water inlet pipe 3 through a water supply pump, a booster pump 5 is arranged at one end of the trailer main body 1 close to the water tank 4, a filter cartridge 6 is arranged at one end of the water inlet pipe 3 close to the water tank 4, a plurality of groups of filter meshes 7 are arranged inside the filter cartridge 6, and the water inlet pipe 3 is connected to the filter cartridge 6 through two connecting components 8;

[0024] The connecting component 8 is used to connect the filter cartridge 6 with the water inlet pipe 3, and the connecting component 8 is composed of a connecting sleeve 9, a movable sleeve 10, a limiting block 11 and a compression spring 12. The connecting sleeve 9 is located at one end of the connecting pipe 22 close to the filter cartridge 6. The movable sleeve 10 is slidably connected to one end of the connecting sleeve 9 close to the filter cartridge 6. Both groups of limiting blocks 11 are slidably connected to one end of the connecting sleeve 9 close to the movable sleeve 10. The compression spring 12 is located inside the movable sleeve 10 and outside the connecting sleeve 9.

[0025] Further, both ends of the compression spring 12 are respectively connected to the connecting sleeve 9 and the movable sleeve 10. The limiting block 11 is designed in an oval structure. The movable sleeve 10 is connected to the limiting block 11 through an accommodating groove 13. By connecting the compression spring 12 with the connecting sleeve 9 and the movable sleeve 10, the compression spring 12 can drive the movable sleeve 10 to displace in cooperation with the connecting sleeve 9.

[0026] Wherein, a fixed cylinder 14 is arranged at one end of the connecting cylinder close to the connecting sleeve 9. Two limiting grooves 15 are opened on the outer side of the fixed cylinder 14. The internal structure size of the limiting groove 15 is designed to correspond to the external structure size of the limiting block 11. The fixed cylinder 14 is connected to the limiting block 11 through the limiting groove 15. When it is necessary to connect the water inlet pipe 3 with the filter cartridge 6, pull the movable sleeve 10 to displace, so that the accommodating groove 13 can displace to the outside of the limiting block 11, make the fixed cylinder 14 contact with the connecting sleeve 9, release the movable sleeve 10, drive the movable sleeve 10 to displace through the compression spring 12, extrude the limiting block 11, so that the limiting block 11 displaces into the internal of the limiting groove 15, thereby enabling the fixed cylinder 14 to be connected to the water inlet pipe 3.

[0027] Secondly, a fitting ring 16 is provided inside the fixing cylinder 14. The fitting ring 16 is connected to the fixing cylinder 14 through elastic blocks 17. At one end of the fixing cylinder 14 inside and away from the fitting ring 16, two sets of pressing rings 18 are provided. The two sets of pressing rings 18 are connected by a connecting spring 19. Sealing rings 20 are provided at both ends of the fitting ring 16 and inside the fixing cylinder 14. When the water inlet pipe 3 is connected to the fixing cylinder 14, the water inlet pipe 3 contacts the fitting ring 16 inside the fixing cylinder 14. The elastic blocks 17 drive the fitting ring 16 to displace, so that the fitting ring 16 can fit the outer side of the water inlet pipe 3. Together with the sealing rings 20, the sealing performance of the connection between the water inlet pipe 3 and the fixing cylinder 14 can be increased. At the same time, when the water inlet pipe 3 is connected to the fixing cylinder 14, the two sets of pressing rings 18 are pressed. Through the connecting spring 19, the two sets of pressing rings 18 are driven to displace, so that the pressing rings 18 press the outer side of the water inlet pipe 3, increasing the connection stability between the water inlet pipe 3 and the fixing cylinder 14. When water flows into the inside of the water inlet pipe 3, multiple sets of filter meshes 7 inside the filter cylinder 6 can filter the water flow, ensuring that the water entering the water-containing cavity of the steam boiler 2 can be filtered once, and the steam coming out of the water-containing cavity of the steam boiler 2 can be filtered twice, thereby improving the purity of the steam ejected by the steam boiler 2. At the same time, the ejection port of the steam boiler 2 is not easily blocked, increasing the service life of the steam boiler 2.

[0028] Furthermore, a circulation pump 21 is provided at one end of the steam boiler 2 away from the water inlet pipe 3. Both the input end and the output end of the circulation pump 21 are fixedly connected with connecting pipes 22. One end of the connecting pipe 22 away from the circulation pump 21 extends into the inside of the steam boiler 2. When the steam boiler 2 operates, the circulation pump 21 is started, and the liquid at the bottom inside the steam boiler 2 is introduced into its top through the connecting pipe 22, so that the liquid inside it can flow, increasing the heating effect.

[0029] Even further, a vertical coil heat exchanger is provided at the top of the steam boiler 2. An electric control box is provided at one end of the trailer main body 1 close to the steam boiler 2. A burner 23 is provided at the bottom of the steam boiler 2. An air duct is provided outside the burner 23. The operation of the steam boiler 2 can be controlled through the electric control box. Starting the burner 23 can heat-treat the steam boiler 2, enabling the steam boiler 2 to operate.

[0030] Even further, a chimney is provided at one end of the vertical coil heat exchanger away from the steam boiler 2. Two sets of support frames are provided at the bottom of the steam boiler 2 and outside the burner 23. The steam boiler 2 is connected to the trailer main body 1 through the support frames. Connecting the steam boiler 2 to the support frames enables the steam boiler 2 to be connected to the trailer main body 1, and the trailer main body 1 can drive the steam boiler 2 to displace.

[0031] In this embodiment, the implementation scenario is specifically as follows: During actual use, the water inlet pipe 3 is connected to the filter cylinder 6. The moving sleeve 10 is pulled to displace, so that the receiving groove 13 can be displaced to the outside of the limiting block 11. The fixed cylinder 14 is brought into contact with the connecting sleeve 9. The moving sleeve 10 is released, and the compression spring 12 drives the moving sleeve 10 to displace, squeezing the limiting block 11, so that the limiting block 11 is displaced into the limiting groove 15, thereby enabling the fixed cylinder 14 to be connected to the water inlet pipe 3. When the fixed cylinder 14 is connected to the water inlet pipe 3, the water inlet pipe 3 contacts the fitting ring 16 inside the fixed cylinder 14. The elastic block 17 drives the fitting ring 16 to displace, so that the fitting ring 16 can fit the outside of the water inlet pipe 3. The cooperation of the sealing ring 20 can increase the sealing performance of the connection between the water inlet pipe 3 and the fixed cylinder 14. At the same time, when the water inlet pipe 3 is connected to the fixed cylinder 14, two sets of extrusion rings 18 are squeezed. Through the connecting spring 19, the two sets of extrusion rings 18 are driven to displace, so that the extrusion rings 18 squeeze the outside of the water inlet pipe 3, increasing the stability of the connection between the water inlet pipe 3 and the fixed cylinder 14. When water flows into the inside of the water inlet pipe 3, multiple sets of filter meshes 7 inside the filter cylinder 6 can filter the water flow, ensuring that the water entering the water storage cavity of the steam boiler 2 can be filtered once, and the steam coming out of the water storage cavity of the steam boiler 2 can be filtered twice, thereby improving the purity of the steam ejected by the steam boiler 2. At the same time, the ejection port of the steam boiler 2 is not easily blocked, increasing the service life of the steam boiler 2. When the steam boiler 2 operates, the circulation pump 21 is started, and the liquid at the bottom inside the steam boiler 2 is introduced into its top through the connecting pipe 22, so that the liquid inside it can flow, enhancing the heating effect. Compared with the existing steam generator, the overall practicality of the steam generator can be improved through the design of the present utility model.

[0032] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
