Description

Technical Field

[0001] This utility model relates to the field of boiler equipment technology, and in particular to a low-pressure to high-pressure steam generator. Background Technology

[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. It usually consists of a pot containing water and a furnace for heating. Water is sequentially added to the pot and heated to boiling point in the furnace to continuously generate steam. The generated steam is transported through pipelines to generate power or be used for heating equipment.

[0003] The patent document with publication number CN 219797168 U discloses a steam generator consisting of a first cylinder and a second cylinder. The first cylinder has a heating chamber, and a water supply pipe is inserted into the upper end of the second cylinder. A piston is fitted on the water supply pipe. By the vertical movement of the piston in the water supply pipe and the conical part set on its bottom wall, the water accumulation in the steam generator is reduced, and water droplets are continuously sprayed through the water supply pipe to continuously generate steam.

[0004] However, it should be noted that this patented method generates steam by spraying water droplets and then evaporating them. This makes the pot (the first cylinder) prone to dry burning, which can easily damage the equipment. Furthermore, the steam generated by this patent is naturally circulating steam, resulting in low steam pressure. When used for power applications, additional pressurization equipment is required, increasing equipment costs.

[0005] Therefore, this utility model provides a low-pressure to high-pressure steam generator that can convert the generated low-pressure steam into high-pressure steam in real time and avoid water accumulation on the inner wall of the pot. Utility Model Content

[0006] The purpose of this invention is to solve the problems existing in the prior art by proposing a low-pressure to high-pressure steam generator.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A low-pressure to high-pressure steam generator, characterized in that it includes a shell, a water spray pipe inserted into the bottom wall of the shell, a heating component embedded in the inner wall of the shell, a pressure pipe at the upper end of the shell, a jet pipe at the upper end of the pressure pipe, a piston embedded in the pressure pipe, a one-way valve at the piston shaft, a drive handle fixedly connected to the bottom end of the piston, a slot frame fixedly connected to the bottom end of the drive handle, a cam rotatably mounted inside the shell within the slot frame, the cam being driven to rotate by a drive device, the cam surface abutting against the inner wall of the slot frame, a connecting rod universally connected to the bottom wall of the slot frame, and a turntable rotatably mounted on the inner wall of the shell at the bottom end of the connecting rod universally connected to the turntable, on which a plurality of stirring rods are arranged in a circular array.

[0009] Preferably, the one-way valve includes a through hole penetrating the piston, the upper end of the through hole is a conical hole and the lower end is a circular hole, a conical plug is embedded in the conical hole, a handle is fixed at the lower end of the conical plug, the diameter of the handle is smaller than the diameter of the circular hole, and a spring is provided between the part of the handle extending out of the bottom end of the circular hole and the bottom wall of the piston.

[0010] Preferably, a claw-shaped bracket is fixed to the upper end of the drive handle, and the bracket is fixedly connected to the piston.

[0011] Preferably, the heating assembly includes a spiral heating tube embedded in the side wall of the housing and a plurality of annular heating tubes embedded in the bottom wall of the housing.

[0012] Preferably, the bottom wall of the turntable has a ring array of multiple sets of stirring rods, which are evenly distributed in the gaps between multiple ring heating tubes.

[0013] Preferably, both the spiral heating tube and the annular heating tube are provided with joints, which penetrate the side wall of the housing.

[0014] Preferably, the two ends of the connecting rod are staggered with the connection parts of the turntable and the slot frame.

[0015] Preferably, the upper end of the water spray pipe is inserted into the housing from the bottom wall of the housing axis, and multiple water inlet holes are evenly distributed on the upper side wall of the water spray pipe.

[0016] Preferably, the turntable has a ring array of multiple scrapers on its side, which abut against the inner wall of the housing.

[0017] Preferably, it also includes an insulation sleeve, which covers the outer wall of the shell.

[0018] Compared with the prior art, this utility model provides a low-pressure to high-pressure steam generator, which has the following beneficial effects:

[0019] 1. During use, water is sprayed into the inner cavity of the housing through the water inlet, and then heated by the heating element to evaporate into steam. At the same time, the cam rotates and moves vertically back and forth against the slot frame. The slot frame descends and drives the piston to descend, and the steam in the housing rushes into the pressure pipe. When the piston rises, the steam in the pressure pipe is compressed and rushes into the jet pipe for transportation. In this way, the conversion of low-pressure steam to high-pressure steam is realized. The overall structure is simpler, saves equipment costs, and eliminates the need for additional steam transmission distance when setting up a booster device. It also avoids the condensation and water accumulation of steam during transportation, which would affect the steam transportation and reduce the probability of steam corrosion.

[0020] While the tank frame moves vertically back and forth, the connecting rod pulls the turntable to rotate and swing back and forth. The stirring rod stirs the water accumulated at the bottom of the shell. The water flow stirring makes the heating more uniform and can also accelerate the rising speed of bubbles in the water, thereby improving the steam production efficiency.

[0021] 2. The heating component includes a spiral heating tube embedded in the side wall of the housing and multiple annular heating tubes embedded in the bottom wall of the housing, which increases the contact area between the water source and the heating component and improves the heating rate.

[0022] 3. The rotating disk has multiple scrapers in a circular array on its side. When the rotating disk reciprocates, the scrapers remove the condensate adhering to the inner wall of the casing, reducing water accumulation.

[0023] 4. The upper end of the water spray pipe inserted into the housing has a tapered constriction. A vertically sliding gravity plug is placed at the constriction. When the steam pressure inside the housing is too high, the air pressure squeezes the water source inside the housing, and then the low-pressure gravity plug at the spray hole blocks the water spray pipe, reducing water delivery. Until the sum of the air pressure inside the housing and the weight of the gravity plug is lower than the water delivery air pressure of the water spray pipe, the gravity plug is pushed up by the water pressure inside the spray pipe, thereby delivering water into the housing. This achieves adaptive regulation of the gas pressure inside the housing. According to the water pressure regulation, the pressure change inside the housing can be controlled, improving the versatility and practicality of use. The water supply is continuous, and there will be no problem of dry burning.

[0024] Other advantages, objectives and features of this invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be taught from practice of this invention.

[0031] The following will refer to the appendix in the embodiments of this utility model. Figure 1-5 The technical solutions in the embodiments of this utility model will be clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0032] Example 1: To address the problems existing in the prior art, this example provides a low-pressure to high-pressure steam generator, including a housing 1. A heating component is embedded in the inner wall of the housing 1. A pressure pipe 2 is provided at the upper end of the housing 1, and the connection between the pressure pipe 2 and the housing 1 is a tapered design. A jet pipe 3 is provided at the upper end of the pressure pipe 2. A piston 4 is embedded in the pressure pipe 2. One-way valves are provided in both the shaft of the piston 4 and the jet pipe 3. A drive handle 6 is fixedly connected to the bottom end of the piston 4. A cantilever is suspended inside the housing 1, and a guide hole is provided at the cantilever. The drive handle 6 passes through the guide hole, allowing the drive handle 6 to slide vertically within the housing 1. The bottom end of the drive handle 6 is fixedly connected to the guide hole. A trough frame 7 is fixedly connected, and a straight groove is provided inside the trough frame 7, which runs through the front and rear side walls of the trough frame 7. A cam 8 is embedded in the straight groove, and the side wall of the cam 8 abuts against the inner walls of the upper and lower sides of the straight groove. The cam 8 is rotatably installed in the housing 1 and is driven to rotate by a drive device, such as a motor or other power equipment. A connecting rod 9 is universally connected to the bottom wall of the trough frame 7, and a turntable 10 is universally connected to the bottom end of the connecting rod 9. A support plate is provided inside the housing 1, and the turntable 10 is rotatably installed on the support plate. Multiple stirring rods 11 are arranged in a ring on the turntable 10. A water spray pipe 17 is inserted into the axial center of the bottom wall of the housing 1, and multiple water inlet holes are evenly distributed on the upper side wall of the water spray pipe 17.

[0033] The specific usage process of this embodiment is as follows:

[0034] In use, water is injected into the spray pipe 17, and the water is sprayed into the inner cavity of the housing 1 through the water inlet. It is then heated by the heating component and evaporated into steam. The steam rises, and at the same time, the drive device drives the cam 8 to rotate. The cam 8 rotates and moves vertically back and forth against the slot frame 7. The slot frame 7 descends, which drives the piston 4 to descend. As the piston 4 descends, the one-way valve on the piston 4 opens, and the one-way valve in the jet pipe 3 closes. The steam in the housing 1 flows into the pressure pipe 2 through the one-way valve. The piston 4 rises, and the one-way valve on the piston 4 closes. The steam in the pressure pipe 2 is compressed. When the steam pressure reaches a certain value, the one-way valve in the jet pipe 3 opens, and the compressed high-pressure steam flows into the jet pipe 3 for transportation. In this way, the conversion of low-pressure steam to high-pressure steam is realized. The overall structure is simpler, saves equipment costs, reduces the steam transmission distance, and avoids the condensation and water accumulation of steam during transportation, which affects the steam transportation. At the same time, it reduces the probability of steam corrosion.

[0035] While the trough frame 7 moves vertically back and forth, the connecting rod 9 pulls the turntable 10 to rotate and swing back and forth. The stirring rod 11 stirs the water accumulated at the bottom of the shell 1. The water flow stirring makes the heating more uniform and can also accelerate the rising speed of bubbles in the water, thereby improving the steam production efficiency.

[0036] Example 2, taking the one-way valve on piston 4 as an example, the one-way valve includes a through hole penetrating piston 4. The upper end of the through hole is a conical hole and the lower end is a round hole. A conical plug 14 is embedded in the conical hole. A handle is fixed to the lower end of the conical plug 14. The diameter of the handle is smaller than the diameter of the round hole. A spring is provided between the part of the handle that extends out of the bottom of the round hole and the bottom wall of piston 4. So when piston 4 descends, the conical plug 14 is pushed up by the steam in the housing 1, the conical hole opens, and the steam enters the pressure pipe 2. When piston 4 rises, the conical plug 14 is pushed down by the steam in the pressure pipe 2 and blocks the conical hole. The steam is retained in the pressure pipe 2, thus completing the one-way flow of steam.

[0037] In embodiment 3, a claw-shaped bracket 5 is fixed to the upper end of the drive handle 6. The bracket 5 is fixedly connected to the piston 4. The bracket 5 and the handle support are spaced apart, so that the handle support can float up and down without affecting the connection between the piston 4 and the drive handle 6.

[0038] In Example 4, the heating assembly includes a spiral heating tube 12 embedded in the side wall of the housing 1 and multiple annular heating tubes 13 embedded in the bottom wall of the housing 1, which increases the contact area between the water source and the heating assembly and improves the heating rate; at the same time, the bottom wall of the turntable 10 has multiple sets of stirring rods 11 arranged in annular array, and the multiple sets of stirring rods 11 are evenly distributed in the gaps between the multiple annular heating tubes 13, so that the distribution of the stirring rods 11 is adapted to the layout of the heating assembly.

[0039] In this embodiment, both the spiral heating tube 12 and the annular heating tube 13 are provided with connectors. The connectors penetrate the side wall of the housing 1. When the heating component is a water pipe heat exchange heating, the connector is a pipe head and is connected to the hot water source; when the heating component is an electric heating, the connector is a power connector and is connected to the power source.

[0040] In embodiment 5, the two ends of the connecting rod 9 are staggered with the connection parts of the turntable 10 and the slot frame 7 to avoid the connection rod 9 having a vertical limit position with the turntable 10 and the slot frame 7, so as to avoid being jammed and affecting the overall operation.

[0041] In Example 6, the turntable 10 has a ring array of multiple scrapers 16 on its side. The scrapers 16 abut against the inner wall of the housing 1. When the turntable 10 reciprocates, the scrapers 16 scrape off the condensate adhering to the inner wall of the housing 1, reducing water accumulation.

[0042] In Example 7, to avoid heat loss from the heating component and waste of resources, an insulation sleeve 15 is wrapped around the outer shell 1. The insulation sleeve 15 is used for heat insulation and to prevent heat loss. The insulation sleeve 15 is divided into multiple parts with channels for pipes to pass through. Each part is fastened together by fasteners, etc., which makes it easy to disassemble and assemble.

[0043] In Example 8, the water spray pipe 17 is inserted into the upper end of the housing 1 and has a tapered opening. A vertically sliding gravity plug 18 is placed at the opening. When the steam pressure inside the housing 1 is too high, the air pressure squeezes the water source inside the housing 1, and then the low-pressure gravity plug 18 at the spray hole blocks the water spray pipe 17, reducing water delivery. At the same time, the reciprocating motion of the piston 4 sends steam out of the housing 1 until the sum of the air pressure inside the housing 1 and the weight of the gravity plug 18 is lower than the water delivery air pressure of the water spray pipe 17. Then the gravity plug 18 is pushed up by the water pressure inside the water spray pipe 17, thereby delivering water into the housing 1. This achieves adaptive adjustment of the gas pressure inside the housing 1 and can regulate the pressure change inside the housing 1 according to the water pressure adjustment. For example, increasing the water pressure increases the pressure inside the housing 1, and decreasing the water pressure decreases the pressure inside the housing 1, improving the versatility and practicality of use.
