Description

Technical Field

[0001] The present invention relates to the field of steam generating equipment, in particular to a steam generating device. Background Art

[0002] A steam generator is a device that heats water and converts it into steam. It is widely used in industries such as industry, energy, healthcare, and food processing. The core function of a steam generator is to use thermal energy (from fuel combustion, electricity, nuclear energy, or other heat sources) to cause liquid water to undergo a phase change, transforming it into a gaseous state called steam.

[0003] The steam generating device usually includes a shell and a heating tube arranged in the shell. A water inlet is provided at one end of the shell and a steam outlet is provided at the other end. Water is passed into the water inlet so that the heating tube heats the water, and the steam generated by the heated water is discharged through the steam outlet.

[0004] The solutions of the existing technology have some shortcomings. The water flowing into the shell through the water inlet forms steam after heating and then flows out directly from the steam outlet. The contact area between the heating tube and the water flow in the water space is small, and the heating tube is prone to dry burning, which is not conducive to ensuring the service life of the heating tube. Summary of the Invention

[0005] In order to increase the contact area between the heating tube and the water flow in the water space, so that the heating tube is not prone to dry burning, thereby ensuring the service life of the heating tube, the present application provides a steam generating device.

[0006] The steam generating device provided in this application adopts the following technical solution: A steam generating device comprises a device body, wherein a water inlet and a steam port are respectively provided at both ends of the device body, the device body is provided with a water space and a steam space respectively connected to the water inlet and the steam port, the device body is provided with a heating pipe for heating the water flow in the water space, the device body is provided with a water inlet groove, the water inlet groove is located in the water space and connected to the water inlet, the water inlet groove is located at the free end of the water space away from the steam space, and the two side groove walls of the water inlet groove are respectively close to the two sides of the width direction of the device body.

[0007] By adopting the above technical solution, water flows into the water inlet trough through the water inlet. When the water in the water body space is heated in the water inlet space, the heating part of the heating tube has a larger contact area with the water in the water body space, which is beneficial to improving the steam generation efficiency. At the same time, it makes the heating tube less likely to dry burn, which is beneficial to ensuring the service life of the heating tube.

[0008] Optionally, the device body includes an upper cover, an intermediate shell and a lower cover, the upper cover and the lower cover are respectively located on both sides of the intermediate shell, the intermediate shell is fixedly connected to a baffle for separating the water space and the steam space, and the baffle is provided with a steam guide port connecting the water space and the steam space; the water inlet trough includes a water inlet section, a scale accumulation section and a connecting section, the water inlet section and the scale accumulation section are both opened in the intermediate shell and are arranged through along the thickness direction of the intermediate shell, the water inlet section and the scale accumulation section are respectively close to the two corners of the intermediate shell, the water inlet is connected to the water inlet section, and the connecting section is located on the side of the intermediate shell facing the lower cover and is connected to the water inlet section and the scale accumulation section.

[0009] By adopting the above technical solution, the baffle is set to separate the water space and the steam space, so that the scale and bubbles generated when heating in the water space are not easily directly entered into the steam space, which is conducive to ensuring the steam discharge volume of the steam port. In addition, when too much scale accumulates in the intermediate shell, after the intermediate shell is removed, the water inlet section and the scale accumulation section set through it are easier to clean.

[0010] Optionally, the steam guide port and the scale accumulation section are located on the same side, the intermediate shell is fixedly connected to a guide bar, the guide bar is located in the water space and is inclined toward the baffle; the intermediate shell is recessed with a steam discharge groove on the side facing the upper cover, the steam discharge groove is located in the steam space, the steam port is connected to the steam discharge groove and is arranged close to the bottom wall of the steam discharge groove, and a plurality of baffle columns are fixedly provided on the bottom wall of the steam discharge groove.

[0011] By adopting the above technical solution, the steam formed by the heated water flow in the water space has a longer flow path when entering the steam space due to the obstruction of the guide strips and the baffles, which makes it easier for scale to be retained and deposited in the water space; and when the water flow in the water space is heated and converted into steam and enters the steam space, it first enters the steam discharge groove and then is discharged through the steam port. The various blocking columns in the steam discharge groove further block the scale in the steam, thereby making it difficult for the scale contained in the steam to enter the steam port and cause blockage of the steam port.

[0012] Optionally, an annular sealing groove is provided on the side of the intermediate shell facing the lower cover, the connecting section is located in the area enclosed by the annular sealing groove, and an annular sealing portion corresponding to the annular sealing groove and snap-fitted with the annular sealing groove is fixedly connected to the side of the lower cover facing the intermediate shell, and an annular sealing ring is provided between the annular sealing portion and the annular sealing groove.

[0013] The adoption of the above technical solution is conducive to ensuring the sealing stability of the position where the water flow is located in the connecting section area, so that the water flow is not likely to leak out of the connecting section area.

[0014] Optionally, a connecting lower groove and a heat-insulating groove are provided on the side of the lower cover facing the intermediate shell, the connecting lower groove corresponds to the position of the connecting section and is located within the area enclosed by the annular sealing portion, and the heat-insulating groove is located outside the area enclosed by the annular sealing portion.

[0015] By adopting the above technical solution, the setting of the connecting lower trough is conducive to further increasing the water capacity in the water space and ensuring the steam generation efficiency. The setting of the insulation groove reduces the contact area between the lower cover and the intermediate shell, thereby reducing heat transfer, which is conducive to avoiding damage to other components due to excessive temperature of the lower cover.

[0016] Optionally, the water inlet section and the scale accumulation section are symmetrically opened, and both the water inlet section and the scale accumulation section include a first side, a second side and a heating arc edge, the first side is perpendicular to the second side, the first side and the second side are arranged in an arc-shaped transition, the two ends of the heating arc edge are respectively connected to the first side and the second side and are arranged in an arc-shaped transition with the first side and the second side, and the heating arc edge is used to heat the water flow in the water space.

[0017] By adopting the above technical solution, the arrangement of the heated arc edge and each arc transition point plays a buffering and guiding role for the water flow in the water space, making it easier for the water flow to flow more stably in the water space.

[0018] Optionally, an isolation sleeve is provided on the side of the intermediate shell facing the lower cover, and the isolation sleeve includes a water inlet isolation part, a connection isolation part and an accumulation isolation part that are fixed in one piece, and the water inlet isolation part, the connection isolation part and the accumulation isolation part are respectively engaged with the water inlet section, the connection section and the scale accumulation section, and the water inlet isolation part is provided with a clearance hole that passes through and is arranged corresponding to the water inlet, and the isolation sleeve is provided with a avoidance notch for avoiding the heating arc edge.

[0019] By adopting the above technical solution, scale in the water space will accumulate on the isolation sleeve when it accumulates. When there is too much scale in the intermediate shell, it is more convenient to quickly clean the scale after removing the intermediate shell and then the isolation sleeve, thereby ensuring the performance of the steam generating device. At the same time, the avoidance of the heating arc edge by the avoidance notch is conducive to ensuring the steam generation effect of the steam generating device on the basis of facilitating the cleaning of the scale.

[0020] Optionally, the isolation sleeve is provided with concave-convex patterns, and the concave-convex patterns are distributed in parallel along the thickness direction of the intermediate shell.

[0021] By adopting the above technical solution, the specific setting of the concave and convex patterns makes it easy to limit the position of scale when scale precipitates and accumulates while ensuring the stability of water flow, further reducing the blockage of scale at the water inlet or steam outlet.

[0022] Optionally, a positioning ridge is fixedly connected to the side away from the water inlet isolation part and the accumulation isolation part, and the groove walls of the water inlet section and the scale accumulation section are provided with positioning grooves corresponding to the positioning ridge and plugged into the positioning ridge, and the positioning groove extends to the side of the intermediate shell facing the lower cover.

[0023] By adopting the above technical solution, the cooperation between the positioning ridges and the positioning grooves plays a further role in limiting the isolation sleeve, which is conducive to fully ensuring the stability of the position of the isolation sleeve.

[0024] Optionally, a limiting rib is fixedly provided on the side of the isolation sleeve facing the lower cover, and an isolation connecting column is fixedly connected to the side of the limiting rib facing the intermediate shell. The intermediate shell is provided with an isolation connecting section corresponding to the isolation connecting column and snap-fitted with the isolation connecting column.

[0025] By adopting the above technical solution, the cooperation between the isolation connecting column and the isolation connecting section makes the connection between the isolation sleeve and the intermediate shell convenient and fast, and facilitates the rapid installation of the isolation sleeve to the required position.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The setting of the baffle separates the water space and the steam space, so that the scale generated during heating in the water space is not easy to directly enter the steam space and cause blockage of the steam port, which is beneficial to ensure the steam discharge capacity of the steam port.

[0027] 2. The steam generated by the water flow heating in the water body space has a longer flow path when entering the steam space through the obstruction of the guide strips and baffles, which makes it easier for scale to be retained and deposited in the water body space.

[0028] 3. When the water flow in the water space is heated and turned into steam and enters the steam space, it first enters the steam discharge groove and then is discharged through the steam port. The retaining columns in the steam discharge groove further block the scale in the steam, so that the scale contained in the steam is not easy to enter the steam port and cause blockage of the steam port.

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-5 This application is described in further detail.

[0036] Example 1.

[0037] The embodiment of the present application discloses a steam generating device. Figure 1 and Figure 2 The steam generating device includes a device body 01, and the device body 01 includes an upper cover 1, an intermediate shell 2 and a lower cover 3, wherein the upper cover 1, the intermediate shell 2 and the lower cover 3 are all roughly rectangular, and the upper cover 1 and the lower cover 3 are respectively located on both sides of the thickness direction of the intermediate shell 2. The upper cover 1, the intermediate shell 2 and the lower cover 3 are fixed by eight bolts distributed in a rectangular shape through themselves.

[0038] Reference Figure 2 and Figure 3The intermediate shell 2 is provided with a water inlet 4 and a steam outlet 5 at both ends of its length. The side of the intermediate shell 2 facing the upper cover 1 is provided with a water space 6 and a steam space 7, which are connected to the water inlet 4 and the steam outlet 5, respectively. A temperature control boss 8 is fixedly connected to the side of the intermediate shell 2 facing the upper cover 1. The temperature control boss 8 is located near the water space 6 and near one side of the intermediate shell 2 in the length direction. A heating pipe 9 is provided at the end of the intermediate shell 2 provided with the steam outlet 5. The heating pipe 9 is U-shaped, and the U-shaped portion of the heating pipe 9 is located within the intermediate shell 2. The U-shaped portion of the heating pipe 9 is located near the bottom of the temperature control boss 8, so that the heating pipe 9 can transfer heat to the temperature control boss 8 when heating, thereby controlling the evaporation of the water through the temperature control boss 8.

[0039] Reference Figure 2 The intermediate shell 2 is provided with a water inlet groove 02, which includes a water inlet section 10, a scale accumulation section 11 and a connecting section 12. The water inlet section 10 and the scale accumulation section 11 are arranged through the thickness direction of the intermediate shell 2. The water inlet section 10 and the scale accumulation section 11 are both located in the water body space 6 and are respectively arranged near the two corners of the bottom of the intermediate shell 2. The temperature control boss 8 is located between the water inlet section 10 and the scale accumulation section 11. The water inlet 4 is eccentrically arranged. Specifically, the water inlet 4 is arranged on one side of the water inlet section 10 and is connected to the water inlet section 10. The connecting section 12 is connected to the water inlet section 10 and the scale accumulation section 11. In the embodiment of the present application, the connecting section 12 extends to the side of the intermediate shell 2 facing the lower cover 3, so as to facilitate the cleaning of the water inlet section 10 and to increase the contact area between the water flow in the water body space 6 and the heating part of the heating tube 9, thereby facilitating the improvement of the steam generation efficiency and making it less likely for the heating tube 9 to dry out, which is conducive to ensuring the service life of the heating tube 9.

[0040] Continue to refer to Figure 2 The side of the intermediate shell 2 facing the upper cover 1 is fixedly connected to a baffle 13 extending along its own width direction. The baffle 13 separates the water space 6 and the steam space 7 so that the scale generated during heating in the water space 6 is not easily able to directly enter the steam space 7 and cause blockage of the steam port 5. The baffle 13 is provided with a steam guide port 14 connecting the water space 6 and the steam space 7. The steam guide port 14 is located on the same side as the scale accumulation section 11. The intermediate shell 2 is fixedly connected to the side facing the shell with a guide bar 15. In the embodiment of the present application, there are two guide bars 15 and both are arranged in an arc shape. Both guide bars 15 are located in the water space 6 and are arranged in an "eight" shape toward the middle of the baffle 13, so that the steam generated by the water flow heating in the water space 6 has a longer flow path when entering the steam space 7, which facilitates more scale deposition and retention in the water space 6.

[0041] Continue to refer to Figure 2A steam discharge groove 16 is recessed on the side of the intermediate shell 2 facing the upper cover 1. The steam discharge groove 16 is located in the steam space 7. The steam port 5 is connected to the steam discharge groove 16 and is arranged close to the bottom groove wall of the steam discharge groove 16. The bottom wall of the steam discharge groove 16 is integrally fixedly connected with a plurality of blocking columns 17. When steam enters the steam space 7, it first enters the steam discharge groove 16 and then is discharged through the steam port 5. The blocking columns 17 in the steam discharge groove 16 further block the scale in the steam, so that the scale contained in the steam is not easy to enter the steam port 5 and cause blockage of the steam port 5.

[0042] Reference Figure 2 and Figure 3 An upper cabin body 18 is recessed on the side of the upper cover 1 facing the intermediate shell 2, and an upper molding 19 corresponding to the position of the baffle 13 is fixedly provided on the side of the upper cover 1 facing the intermediate shell 2. The upper molding 19 separates the upper cabin body 18 into a water cabin body 181 and a steam cabin body 182. The upper molding 19 is provided with an upper guide port 20 corresponding to the position of the steam guide port 14. The upper guide port 20 is connected with the water cabin body 181 and the steam cabin body 182. When the upper cover 1 and the intermediate shell 2 are connected, the baffle 13 and the baffle 13 molding press against each other, and the water cabin body 181 and the steam cabin body 182 are connected with the water space 6 and the steam space 7 respectively. The steam generated in the water space 6 enters the steam space 7 through the steam guide port 14 and the upper guide port 20.

[0043] Continue to refer to Figure 2 and Figure 3 To ensure a tight seal between the intermediate housing 2 and the upper cover 1, an upper sealing portion 21 is provided on the side of the intermediate housing 2 facing the upper cover 1. This upper sealing portion 21 is annular and encloses the edge of the temperature-control boss 8, positioning the latter outside the area enclosed by the first sealing portion. An upper sealing groove 22, corresponding to and interlocking with the upper sealing portion 21, is defined on the side of the upper cover 1 facing the intermediate housing 2. An upper sealing ring 23 is embedded within the upper sealing groove 22. When the intermediate housing 2 and upper cover 1 are connected, the upper sealing portion 21 engages with the upper sealing groove 22 and presses against the upper sealing ring 23.

[0044] Continue to refer to Figure 2 and Figure 3 To ensure the sealing between the intermediate housing 2 and the lower cover 3, the intermediate housing 2 is provided with a closed annular sealing groove 24 on the side facing the lower cover 3. The connecting section 12 is located in the area surrounded by the annular sealing groove 24. An annular sealing ring 25 is embedded and installed in the annular sealing groove 24. The lower cover 3 is fixedly connected to the side facing the intermediate housing 2 with an annular sealing portion 26 corresponding to the annular sealing groove 24 and snap-fitting with the annular sealing groove 24. When the intermediate housing 2 is connected to the lower cover 3, the annular sealing portion 26 is inserted into the annular sealing groove 24 and presses against the annular sealing ring 25.

[0045] Continue to refer to Figure 2 and Figure 3 The lower cover 3, facing the intermediate housing 2, is provided with a lower connecting groove 27 and a heat-insulating groove 28. The lower connecting groove 27 corresponds to the connecting section 12 and is located within the area enclosed by the annular seal 26. The heat-insulating groove 28 is located outside the area enclosed by the annular seal 26. When the intermediate housing 2 and the lower cover 3 are connected, the lower connecting groove 27 communicates with the connecting section 12, thereby further increasing the water volume within the water space 6 and ensuring steam generation efficiency. The provision of the heat-insulating groove 28 also reduces heat transfer, helping to prevent damage to other components of the lower cover 3 due to excessive temperatures.

[0046] Reference Figure 2 In this embodiment, the water inlet section 10 and the scale accumulation section 11 are symmetrically arranged along the midline of the intermediate shell 2 in the width direction. Specifically, each section includes a first side 29, a second side 30, and a heating arc 31. The first side 29 is perpendicular to the second side 30 and extends along the length of the intermediate shell 2, while the second side 30 extends along the width of the intermediate shell 2. The connection between the first side 29 and the second side 30 forms an arc-shaped transition through a rounded corner. The groove wall of the connecting section 12 is connected to the second side 30 of the water inlet section 10 and the scale accumulation section 11.

[0047] Continue to refer to Figure 2 The two ends of the heating arc edge 31 are connected to the first side edge 29 and the second side edge 30 respectively. The connection points between the two ends of the heating arc edge 31 and the first side edge 29 and the second side edge 30 are also rounded to form an arc transition, and the corners of the heating arc edge 31 facing the upper cover 1 and the lower cover 3 are rounded to achieve stable guidance of the water flow and steam in the water space 6. The heating arc edge 31 is close to the U-shaped part of the heating tube 9 so that the heating arc edge 31 is used to heat the water flow in the water space 6.

[0048] Reference Figure 1 and Figure 3 A mounting hole 32 is provided on the side of the upper cover 1 away from the intermediate shell 2, which corresponds to the temperature control boss 8 and is penetrated by the upper cover 1. A thermostat 33 is installed in the mounting hole 32. The temperature control boss 8 is located at the bottom of the thermostat 33. A pressing piece 34 is provided on the top of the thermostat 33. The pressing piece 34 includes a U-shaped main body 341 and connecting pieces 342 fixedly installed on both sides of the U-shaped main body 341. The U-shaped main body 341 is mounted on the thermostat 33. The two connecting pieces 342 are fixed to the end face of the upper cover 1 by screws 35, thereby achieving the fixation between the thermostat 33 and the upper cover 1.

[0049] Reference Figure 1A round tube 36 is fixedly provided on the side of the upper cover 1 away from the intermediate shell 2, and a temperature fuse 37 is provided in the round tube 36. In the embodiment of the present application, the round tube 36 is selected as a Teflon tube. One end of the heating tube 9 is connected to the positive pole 38 of the power supply and the other end is connected to the negative pole 39 of the power supply for connecting to the power supply to heat the water body. The temperature fuse 37 is set at the positive pole 38 of the power supply to protect the circuit.

[0050] The implementation principle of a steam generating device in an embodiment of the present application is as follows: when water flows into the water inlet section 10 through the water inlet 4, the water flow in the water space 6 also enters the scale accumulation section 11 synchronously through the connecting section 12, so that the contact area between the heating part of the heating tube 9 and the water flow in the water space 6 is larger, which is beneficial to improving the steam generation efficiency, and at the same time makes it less likely for the heating tube 9 to dry burn, which is beneficial to ensuring the service life of the heating tube 9. In addition, the setting of the baffle 13 separates the water space 6 and the steam space 7, so that the scale generated during heating in the water space 6 is not easy to directly enter the steam space 7 and cause blockage of the steam port 5, which is beneficial to ensuring the steam discharge volume of the steam port 5. In addition, when too much scale accumulates in the intermediate shell 2, after the intermediate shell 2 is removed, the water inlet section 10 and the scale accumulation section 11 set through it are easier to clean.

[0051] Example 2.

[0052] Reference Figure 4 and Figure 5 The main difference between the embodiment of the present application and embodiment 1 is that, in the embodiment of the present application, an isolation sleeve 40 is further provided, and the isolation sleeve 40 is provided on the side of the intermediate shell 2 facing the lower cover 3. Specifically, the isolation sleeve 40 includes an integrally fixed water inlet isolation part 401, a connecting isolation part 402 and an accumulation isolation part 403, wherein the water inlet isolation part 401, the connecting isolation part 402 and the accumulation isolation part 403 are respectively engaged with the water inlet section 10, the connecting section 12 and the scale accumulation section 11, and the water inlet isolation part 401 is provided with a clearance hole 41 that passes through and is corresponding to the water inlet 4. When the water inlet isolation part 401 is inserted into the water inlet section 10, the clearance hole 41 corresponds to the water inlet 4 to facilitate the flow of water into the water inlet section 10.

[0053] Reference Figure 5The water inlet isolation portion 401 and the accumulation isolation portion 403 are both provided with a clearance notch 42. The clearance notch 42 corresponds to the position of the heating arc edge 31, so as to facilitate the clearance of the heating arc edge 31 and ensure the steam generation efficiency. The side of the isolation shell 40 facing the lower cover 3 is fixedly connected to the limiting rib 43. When the limiting rib 43 contacts the side of the isolation shell facing the lower cover 3, the water inlet isolation portion 401, the connection isolation portion 402, and the accumulation isolation portion 403 are stably inserted into the water inlet section 10, the connection section 12, and the scale accumulation section 11, respectively. The side edges of the water inlet isolation portion 401 and the accumulation isolation portion 403 are respectively attached to the first side edge 29 and the second side edge 30 of the water inlet section 10 and the scale accumulation section 11.

[0054] Continue to refer to Figure 5 The limiting edge 43 is fixedly connected to one side of the intermediate shell 2 with two isolating connecting columns 44, and the intermediate shell 2 is opened on the side facing the lower cover 3 with an isolating connecting section 45 corresponding to the two isolating connecting columns 44 and respectively engaged with the two isolating connecting columns 44, so as to further facilitate the rapid installation of the isolation sleeve 40 to the required specified position.

[0055] Reference Figure 4 and Figure 5 In order to further ensure the stability of the position of the isolation sleeve 40 after installation, a positioning ridge 46 is fixedly connected to the side away from the water inlet isolation part 401 and the accumulation isolation part 403. In the embodiment of the present application, there are two positioning ridges 46 on each side distributed along the length direction of the isolation shell. The groove walls of the water inlet section 10 and the scale accumulation section 11 are both provided with positioning grooves 47 corresponding to the positioning ridges 46 and plugged into the positioning ridges 46. The positioning grooves 47 extend to the side of the intermediate shell 2 facing the lower cover 3, so as to further limit the position of the isolation sleeve 40 through the cooperation of the positioning ridges 46 and the positioning grooves 47.

[0056] Continue to refer to Figure 4 and Figure 5 The water inlet isolation part 401, the connecting isolation part 402 and the accumulation isolation part 403 are respectively provided with concave and convex patterns 48 on the side facing the water inlet section 10, the connecting section 12 and the scale accumulation section 11, that is, the inner sides of the water inlet isolation part 401, the connecting isolation part 402 and the accumulation isolation part 403. There are multiple concave and convex patterns 48 distributed in parallel along the thickness direction of the intermediate shell 2, so as to limit the position of scale when scale precipitates and accumulates while ensuring the stability of water flow, thereby further reducing the blockage of scale at the water inlet 4 or the steam port 5.

[0057] The embodiment of the present application mainly prevents the scale generated during heating in the water space 6 from directly entering the steam space 7 and causing blockage of the steam port 5. Furthermore, the isolation sleeve 40 is provided to achieve concentrated accumulation of scale in the water inlet section 10, the connection section 12 and the scale accumulation section 11. Therefore, when there is too much scale in the intermediate shell 2, the intermediate shell 2 is removed and then the isolation sleeve 40 is removed to quickly clean the scale, thereby ensuring the performance of the steam generating device.

[0058] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
