Description

Technical Field

[0001] The present application relates to the technical field of asphalt preparation auxiliary equipment, and in particular to a hot steam generator. Background Art

[0002] During the asphalt production process, industrial steam is needed to heat equipment or instrument jackets and other tools. Tap water is heated by burning coal, gas, oil or electric heating pipes to obtain high-temperature steam that is used to supply heat energy for subsequent asphalt preparation processes.

[0003] However, in the asphalt preparation process disclosed in the prior art, steam is prepared by directly heating tap water, and the generated steam is transported to a pressure chamber for heating the steam through a pipeline. After being heated in the pressure chamber, high-temperature hot steam is generated to meet subsequent use.

[0004] In this regard, the inventors believe that when the generated steam is transmitted through the pipeline, the lower temperature steam condenses due to contact with the outer wall of the pipeline, and thus adheres to the outside of the pipe wall for a long time, causing damage to the pipeline. Utility Model Content

[0005] The embodiment of the present application provides a hot steam generator to solve the defect in the prior art that low-temperature steam condenses and adheres to the pipe wall, causing damage to the pipe, thereby achieving the purpose of increasing the service life of the pipe.

[0006] The present invention provides a steam generator comprising:

[0007] The steam generating box is provided with a first cavity for accommodating tap water; the bottom of the steam generating box is provided with a first heating pipe for heating the tap water;

[0008] The steam heating box is provided with a second cavity for accommodating hot steam, and a second heating pipe is fixedly connected to the outer wall of the steam heating box;

[0009] a steam delivery pipe connected between the steam generating box and the steam heating box, wherein the height of one end of the steam delivery pipe close to the steam generating box is lower than the height of the other end of the steam delivery pipe close to the steam heating box;

[0010] The condensation plate is provided with a plurality of vent holes for steam to pass through, and the condensation plate is detachably connected to the inner cavity of the higher end of the steam delivery pipe.

[0011] By adopting the above technical means, the steam generated by the steam generating box can be gradually transmitted to the steam heating box along the steam conveying pipe due to its own high temperature. During the transmission process, the steam with a lower temperature condenses on the inner wall of the steam conveying pipe, and part of the steam adheres to the condensation plate. The condensed steam gathers into larger water droplets along the bottom wall of the condensation plate toward the inner wall of the steam conveying pipe. Then, the larger water droplets move from the inner wall of the steam conveying pipe at a higher position to the lower side, and gradually gather the small water droplets attached to the inner wall of the steam conveying pipe during the movement, thereby reducing the probability of the steam with a lower temperature condensing and adhering to the pipe wall, and reducing the probability of the steam condensation adhering to the inner wall of the pipe for a long time and damaging the inner wall of the pipe, thereby achieving the purpose of improving the service life of the pipe.

[0012] Optionally, the steam delivery pipe includes a condensation section and a delivery section connected in sequence, the condensation section is implemented in a U shape, one end of the condensation section is connected to the first cavity of the steam generation box, and the end of the delivery section away from the condensation section is connected to the second cavity of the steam generation box;

[0013] Wherein, the condensation plate is detachably connected to the inner cavity of the conveying section of the steam conveying pipe.

[0014] By adopting the above-mentioned technical means, when steam condenses on the inner wall of the steam conveying pipe, the steam condenses on the bottom wall of the condensation plate and moves along the inner wall of the conveying section of the steam conveying pipe, gradually gathering into larger water droplets and flowing to the bottom wall of the condensation section of the steam conveying pipe. The condensed steam is stored in the condensation section of the steam conveying pipe, and the probability of the condensed steam being distributed at intervals on the inner wall of the steam conveying pipe is reduced, thereby reducing the probability of damage to the inner wall of the steam conveying pipe.

[0015] Optionally, at least three protrusions are fixedly connected to the inner cavity wall of the conveying section of the steam conveying pipe, and the protrusions are distributed at intervals along the inner cavity wall of the conveying section, and the top walls of the protrusions are used to fit with the condensation plate.

[0016] By adopting the above technical means, the condenser plate will be damaged due to long-term contact with condensed steam during use. By placing the condenser plate on top of the protrusions and using three protrusions to support the condenser plate, the efficiency of users replacing the condenser plate is improved.

[0017] Optionally, at least three positioning grooves are formed on the outer wall of the condensation plate, each positioning groove is used to accommodate one of the protrusions, and the depth of the positioning groove is less than the thickness of the condensation plate.

[0018] By adopting the above technical means, the condenser plate cooperates with the protrusion through the positioning groove provided on itself, thereby fixing the movement direction of the condenser plate along the inner cavity wall of the conveying section of the steam conveying pipe, reducing the probability of the condenser plate sliding along the circumferential side of the inner cavity wall of the conveying section of the steam conveying pipe.

[0019] Optionally, the outer edge of the condensation plate is provided with a chamfer.

[0020] By adopting the above technical means, by providing a chamfer on the outer peripheral wall of the condenser plate, the chamfer can reduce the area of ​​the end of the condenser plate, thereby making it easier for the condenser plate to extend into the steam delivery pipe and improving the installation efficiency of the condenser pipe.

[0021] Optionally, a recovery hole is opened at the bottom of the condensation section of the steam conveying pipe, and a recovery pipe is arranged below the recovery hole. One end of the recovery pipe is connected to the condensation section of the steam conveying pipe, and the other end of the recovery pipe is connected to the first cavity of the steam generating box.

[0022] By adopting the above-mentioned technical means, a recovery hole is opened at the bottom of the condensation section of the steam conveying pipe. The recovery hole is used to guide the water droplets gathered at the bottom of the condensation section of the steam conveying pipe to escape from the inner cavity, and guide the water droplets to the steam generating box through the recovery pipe, thereby reducing the probability of the steam conveying channel being blocked due to the steam gathered in the condensation section of the steam conveying pipe.

[0023] Optionally, also include:

[0024] A receiving tray is connected to one end of the recovery pipe near the condensation section of the steam delivery pipe. The height of the top wall of the receiving tray gradually decreases from the edge to the center, and a connecting hole is opened at the center of the receiving tray, and the connecting hole is connected to the inner cavity of the recovery pipe.

[0025] By adopting the above-mentioned technical means, the top of the receiving tray receives water droplets from the inner cavity of the condensate section of the steam delivery pipe that has separated from the recovery hole. The received water droplets then move toward the recovery pipe along the inclined inner wall of the top of the receiving tray, thereby improving the efficiency of recovering the condensed steam.

[0027] The embodiment of the present application adopts the method that the steam generated by the steam generating box has a high temperature and can be gradually transmitted to the steam heating box along the steam conveying pipe. During the transmission process, the steam with a lower temperature condenses on the inner wall of the steam conveying pipe, and part of the steam adheres to the condensation plate. The condensed steam gathers into larger water droplets along the bottom wall of the condensation plate toward the inner wall of the steam conveying pipe. Then, the larger water droplets move from the inner wall of the steam conveying pipe at a higher position toward the lower side, and gradually gather the small water droplets attached to the inner wall of the steam conveying pipe during the movement, thereby reducing the probability of the steam with a lower temperature adhering to the pipe wall after condensation, and reducing the probability of the steam condensation adhering to the inner wall of the pipe for a long time and damaging the inner wall of the pipe, thereby achieving the purpose of improving the service life of the pipe.

For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0033] The embodiment of the present application provides a hot steam generator, which includes:

[0034] The steam generating box 1 is provided with a first cavity for containing tap water; a first heating pipe 2 for heating tap water is provided at the bottom of the steam generating box 1;

[0035] The steam heating box 3 is provided with a second cavity for accommodating hot steam, and a second heating pipe 4 is fixedly connected to the outer wall of the steam heating box 3;

[0036] The steam delivery pipe 5 is connected between the steam generating box 1 and the steam heating box 3. The height of the end of the steam delivery pipe 5 close to the steam generating box 1 is lower than the height of the end of the steam delivery pipe 5 close to the steam heating box 3.

[0037] The condensation plate 6 is provided with a plurality of vent holes 61 for steam to pass through, and the condensation plate 6 is detachably connected to the inner cavity of the higher end of the steam delivery pipe 5 .

[0038] Exemplarily, the steam generating box 1 is cylindrical, and the first heating tube 2 at the bottom of the steam generating box 1 can be implemented as a coil composed of a magnetic coil, and the first heating tube 2 is connected to the bottom of the steam generating box 1 by bolts.

[0039] At the same time, the second heating tube 4 is also implemented as a magnetic coil. The second heating tube 4 is wound around the outside of the steam heating box 3. It can use electrical energy to generate thermal energy and heat the steam in the steam heating box 3, thereby increasing the temperature of the steam in the steam heating box 3.

[0040] One end of the steam conveying pipe 5 is connected to the steam generating box 1 by a threaded connection, and the other end of the steam conveying pipe 5 is connected to the steam heating box 3 by a threaded connection. The height of the steam conveying pipe 5 close to the steam heating box 3 is greater than the height close to the steam generating box 1, which can greatly facilitate the condensation of low-temperature steam along the inner cavity of the steam conveying pipe 5 toward the side of the steam generating box 1, thereby avoiding the probability of excessive dispersion of steam in the steam conveying pipe 5 after condensation, thereby damaging the inner wall of the steam conveying pipe 5.

[0041] The outer diameter of the condensation plate 6 is smaller than the inner diameter of the steam delivery pipe 5. It is used to contact the steam in the steam delivery pipe 5 and provide an attachment point for the steam with a lower temperature in the steam delivery pipe 5, thereby accelerating the condensation of the lower temperature steam into larger water droplets that can move along the inner wall of the steam delivery pipe 5, reducing the probability of damage caused by the steam contacting the inner wall of the steam delivery pipe 5 for a long time.

[0042] By adopting the above technical means, the steam generated by the steam generating box 1 can be gradually transmitted to the steam heating box 3 along the steam conveying pipe 5 due to its own high temperature. During the transmission process, the steam with a lower temperature condenses on the inner wall of the steam conveying pipe 5, and part of the steam adheres to the condensation plate 6. The condensed steam gathers into larger water droplets along the bottom wall of the condensation plate 6 toward the inner wall of the steam conveying pipe 5. Then, the larger water droplets move from the inner wall of the steam conveying pipe 5 at a higher position to the lower side, and gradually gather the small water droplets attached to the inner wall of the steam conveying pipe 5 during the movement, thereby reducing the probability of the steam with a lower temperature condensing and adhering to the pipe wall, and reducing the probability of the steam condensation adhering to the inner wall of the pipe for a long time and damaging the inner wall of the pipe, thereby achieving the purpose of improving the service life of the pipe.

[0043] In some embodiments, the steam delivery pipe 5 includes a condensation section 51 and a delivery section 52 connected in sequence. The condensation section 51 is implemented in a U shape. One end of the condensation section 51 is connected to the first cavity of the steam generating box 1, and the end of the delivery section 52 away from the condensation section 51 is connected to the second cavity of the steam generating box 1.

[0044] The condensation plate 6 is detachably connected to the inner cavity of the conveying section 52 of the steam conveying pipe 5 .

[0045] Illustratively, the condensation section 51 and the conveying section 52 are integrally formed, the conveying section 52 is implemented as an inclined straight line, and the height of the conveying section 52 used to connect to the condensation section 51 is greater than the height of the conveying section 52 away from the end of the condensation section 51.

[0046] By adopting the above-mentioned technical means, when steam condenses on the inner wall of the steam conveying pipe 5, the steam condenses on the bottom wall of the condensation plate 6 and moves along the inner wall of the conveying section 52 of the steam conveying pipe 5, gradually gathering into larger water droplets and flowing to the bottom wall of the condensation section 51 of the steam conveying pipe 5, and the condensed steam is stored in the condensation section 51 of the steam conveying pipe 5, and the probability of the condensed steam being distributed at intervals on the inner wall of the steam conveying pipe 5 is reduced, thereby reducing the probability of damage to the inner wall of the steam conveying pipe 5.

[0047] In some embodiments, at least three protrusions are fixedly connected to the inner wall of the conveying section 52 of the steam conveying pipe 5 . The protrusions are spaced apart along the inner wall of the conveying section 52 , and the top walls of the protrusions are used to fit with the condensation plate 6 .

[0048] The bump and the steam delivery pipe 5 are integrally formed by welding, and are used to support the condensation plate 6 by three-point support, which can facilitate the installation of the condensation plate 6 and reduce the cost of changing the inner wall shape of the steam delivery pipe 5.

[0049] By adopting the above technical means, the condensation plate 6 will be damaged due to long-term contact with condensed steam during use. By placing the condensation plate 6 on the top of the protrusion and using three protrusions to support the condensation plate 6, the efficiency of users replacing the condensation plate 6 is improved.

[0050] In some embodiments, at least three positioning grooves are formed on the outer wall of the condensation plate 6 , each positioning groove is used to accommodate a protrusion, and the depth of the positioning groove is less than the thickness of the condensation plate 6 .

[0051] By adopting the above-mentioned technical means, the condensation plate 6 cooperates with the protrusion through the positioning groove provided therein, thereby fixing the movement direction of the condensation plate 6 along the inner cavity wall of the conveying section 52 of the steam conveying pipe 5, thereby reducing the probability of the condensation plate 6 sliding along the circumferential side of the inner cavity wall of the conveying section 52 of the steam conveying pipe 5.

[0052] In some embodiments, the outer edge of the water condensation plate 6 is provided with a chamfer.

[0053] By adopting the above technical means, by providing a chamfer on the outer peripheral wall of the condensation plate 6, the chamfer can reduce the area of ​​the end of the condensation plate 6, thereby making it easier for the condensation plate 6 to extend into the steam delivery pipe 5 and improving the installation efficiency of the condensation pipe.

[0054] In some embodiments, a recovery hole 511 is opened at the bottom of the condensation section 51 of the steam delivery pipe 5, and a recovery pipe 7 is arranged below the recovery hole 511. One end of the recovery pipe 7 is connected to the condensation section 51 of the steam delivery pipe 5, and the other end of the recovery pipe 7 is connected to the first cavity of the steam generating box 1.

[0055] By adopting the above-mentioned technical means, a recovery hole 511 is opened at the bottom of the condensation section 51 of the steam conveying pipe 5. The recovery hole 511 is used to guide the water droplets gathered at the bottom of the condensation section 51 of the steam conveying pipe 5 to escape from the inner cavity, and guide the water droplets to the steam generating box 1 through the recovery pipe 7, thereby reducing the probability that the steam collected in the condensation section 51 of the steam conveying pipe 5 will cause the steam conveying channel to be blocked.

[0056] In some embodiments, the hot steam generator provided in the embodiments of the present application further includes:

[0057] The receiving tray 8 is connected to one end of the condensate section 51 of the recovery pipe 7 close to the steam delivery pipe 5. The height of the top wall of the receiving tray 8 gradually decreases from the edge to the center, and a connecting hole 81 is opened at the center of the receiving tray 8. The connecting hole 81 is connected to the inner cavity of the recovery pipe 7.

[0058] By adopting the above-mentioned technical means, the top of the receiving tray 8 receives water droplets that separate from the inner cavity of the condensation section 51 of the steam delivery pipe 5 from the recovery hole 511, and then the received water droplets move toward the recovery pipe 7 along the inclined inner wall of the top of the receiving tray 8, thereby improving the efficiency of recovering the condensed steam.

[0059] The implementation principle of a hot steam generator provided in the present application is as follows: the steam generated by the steam generating box 1 can be gradually transmitted to the steam heating box 3 along the steam conveying pipe 5 due to its own high temperature. During the transmission process, the steam with a lower temperature condenses on the inner wall of the steam conveying pipe 5, and at the same time, part of the steam adheres to the condensation plate 6. The condensed steam gathers into larger water droplets along the bottom wall of the condensation plate 6 toward the inner wall of the steam conveying pipe 5. Then, the larger water droplets move from the inner wall of the steam conveying pipe 5 at a higher position toward the lower side, and gradually gather the small water droplets attached to the inner wall of the steam conveying pipe 5 during the movement, thereby reducing the probability of the steam with a lower temperature adhering to the pipe wall after condensation, and reducing the probability of steam condensation adhering to the inner wall of the pipe for a long time and damaging the inner wall of the pipe, thereby achieving the purpose of increasing the service life of the pipe.

[0060] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on the differences from other embodiments.
