Description

Technical Field

[0001] This utility model relates to a steam generating device, and more particularly to a steam generating device for stable steam supply. Background Technology

[0002] In the production of enameled wire, the enameled wire production line first stretches copper wire of the required specifications using a wire stretching machine, then coats the surface of the copper wire with insulating varnish, bakes it to form enameled wire, and then winds the enameled wire.

[0003] In the copper wire production process, high-temperature steam generated by a steam generator is needed to prevent the copper wire from oxidizing and discoloring, and also to sterilize it. Existing steam generators produce high-temperature steam through the synergistic action of a waste heat collection device, a steam water supply device, and a waste heat exchange steam generation device. However, in actual production, after water is added to the steam generator, the temperature inside the steam generator drops, causing a significant drop in the temperature of the waste heat collection device and the waste heat exchange steam generation device. This results in an unstable steam supply, especially for enameled wire produced under low-temperature conditions, where the requirements for oxidation and discoloration are very high. The instability of the steam supply will seriously affect the stability of the enameled wire quality.

[0004] Therefore, it is necessary to design a steam generation device with a stable steam supply. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, where water replenishment to the steam generator causes a temperature drop within the generator, leading to a significant decrease in the temperature of the waste heat collection and waste heat exchange steam generation devices, resulting in unstable steam supply, especially for enameled wire produced under low-temperature conditions where the requirements for oxidation and discoloration are very high, the instability of steam supply will seriously affect the stability of the enameled wire quality, this utility model provides a steam generation device with stable steam supply.

[0006] The technical solution of this utility model is as follows: a steam generating device for stable steam supply, comprising a steam generating tank, a tank cover, a steam pressure relief valve, a heating component, a three-way water inlet pipe, an exchanger, a water supply pipe, a first valve, a steam outlet pipe, a third valve, a three-way water delivery pipe, a controller, and an electrical switch. The top of the steam generating tank is covered with a tank cover, and a steam pressure relief valve is connected to and communicates with the tank cover. A heating component for generating steam is installed at the bottom of the steam generating tank. An exchanger is installed on the left side of the steam generating tank, and a water supply pipe connects the steam generating tank and the exchanger. A three-way water inlet pipe is connected to and communicates with the front of the exchanger. A first valve is installed at the bottom of the exchanger, and a steam outlet pipe runs through the top of the steam generating tank. A third valve is installed at the upper end of the steam outlet pipe, and a three-way water supply pipe is connected to the third valve. A controller is installed on the right side of the steam generator. The controller contains multiple sets of electrical switches, as well as a ball valve, a rotating shaft, a piston, a float, a mounting base, a connecting rod, and a liquid level sensor. A ball valve is installed at the end of the three-way water inlet pipe located outside the exchanger, and a mounting base is installed at the end of the three-way water inlet pipe located inside the exchanger. A rotating shaft is rotatably mounted on the mounting base, and a connecting rod is fixedly connected to the rotating shaft. A piston is slidably mounted at the end of the three-way water inlet pipe away from the ball valve, and the connecting rod slides in contact with the piston. A float is installed at the end of the connecting rod away from the mounting base. A liquid level sensor and a buzzer are installed on the left side of the exchanger.

[0007] In one embodiment, the heating assembly includes a partition, wires, heating rods, and a power switch. The partition is fixedly connected inside the steam generating chamber, and heating rods corresponding to the number of power switches are installed on the partition. The power switch is installed inside the steam generating chamber, and multiple sets of wires are connected to the front side of the power switch. The other end of the wires is connected to the heating rods.

[0008] In one embodiment, a pressure gauge and a second valve are also included. The pressure gauge is installed on the top of the steam generator, and the second valve is installed below the pressure gauge. The lower end of the pressure gauge is connected to the steam outlet pipe.

[0009] In one embodiment, the steam outlet pipe is further provided with a hydrophobic and breathable membrane, a drain pipe and a filter screen. The steam outlet pipe is provided with a hydrophobic and breathable membrane inside, and the lower end of the steam outlet pipe is connected to and communicates with the drain pipe. Multiple filter screens are embedded inside the drain pipe.

[0010] In one embodiment, the device also includes a current transformer, a warning light, and an alarm. Each set of switches has two incoming terminals at the top and two outgoing terminals at the bottom. A current transformer is installed on the incoming terminal of the switch. A warning light corresponding to the current transformer is installed inside the controller. An alarm is installed on the top of the controller.

[0014] Compared with the prior art, this utility model provides a stable steam generator with the following advantages: 1. When the liquid level in the exchanger changes, the float moves up and down. The change in the height of the float causes the connecting rod to control the piston to slide and close and open the three-way water inlet pipe, so that the water inlet pipe automatically replenishes water to the exchanger, ensuring that the water level in the exchanger is maintained stably within a certain range. This prevents the temperature in the steam generator from dropping and causing unstable steam output when too much water is added to the steam generator at one time, thus achieving the purpose of providing stable steam for enameled wire production, avoiding affecting the stability of the enameled wire quality, and ensuring that the enameled wire is free from oxidation.

[0015] 2. By contacting the steam inside the steam outlet pipe with a pressure gauge, the steam pressure is monitored and controlled to ensure that the steam pressure does not exceed the set safety limit and to avoid potential safety hazards.

[0016] 3. The water content in the steam is intercepted by the hydrophobic and breathable membrane, and the steam then enters the interior of the three-way water pipe through the hydrophobic and breathable membrane, thereby reducing the water content in the steam and improving the quality of the steam.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1: Steam generator with stable steam supply, please refer to [link / reference]. Figures 1-8The system includes a steam generator 1, a cover 2, a steam pressure relief valve 201, a heating element, a three-way water inlet pipe 3, an exchanger 4, a water supply pipe 401, a first valve 5, a steam outlet pipe 6, a third valve 7, a three-way water supply pipe 701, a controller 8, and a power switch 9. The top of the steam generator 1 is covered by the cover 2, and the steam pressure relief valve 201 is connected to and communicates with the cover 2. When the internal pressure of the steam generator 1 is too high, the steam pressure relief valve 201 actively relieves the pressure in the steam generator 1, allowing the steam inside the steam generator 1 to cool down. The air pressure is maintained within a safe range. A heating element for generating steam is installed at the bottom of the steam generator 1. An exchanger 4 is installed on the left side of the steam generator 1. A glass plate 23 is embedded in the front of the exchanger 4, allowing direct viewing of the water level inside. A three-way water inlet pipe 3 is connected to the front of the exchanger 4. A first valve 5 is installed at the bottom of the exchanger 4. A steam outlet pipe 6 runs through the top of the steam generator 1. A third valve 7 is installed at the upper end of the steam outlet pipe 6. A three-way water supply pipe 701 is connected to the door 7. A controller 8 is installed on the right side of the steam generator 1. The controller 8 contains four sets of electric switches 9, as well as a ball valve 301, a rotating shaft 302, a piston 303, a float 15, a mounting base 17, a connecting rod 21, and a liquid level sensor 16. A ball valve 301 is installed at the end of the three-way water inlet pipe 3 located outside the exchanger 4, and a mounting base 17 is installed at the end of the three-way water inlet pipe 3 located inside the exchanger 4. A rotating shaft 302 is rotatably mounted on the mounting base 17. A connecting rod 21 is fixedly connected to the rotating shaft 302. A piston 303 is slidably installed at the end of the three-way water inlet pipe 3 away from the ball valve 301. The connecting rod 21 slides in contact with the piston 303. A float ball 15 is installed at the end of the connecting rod 21 away from the mounting base 17. A liquid level sensor 16 and a buzzer 1601 are installed on the left side of the exchanger 4. The signal output terminal of the liquid level sensor 16 is electrically connected to the signal input terminal of the controller 8. The signal output terminal of the controller 8 is electrically connected to the signal input terminal of the buzzer 1601.

[0029] Please see Figure 2 and Figure 3 The heating assembly includes a partition 11, wires 12, heating rods 13, and a power switch 14. The partition 11 is fixedly connected inside the steam generating chamber 1. Heating rods 13 corresponding to the number of switches 9 are installed on the partition 11. The power switch 14 is installed inside the steam generating chamber 1. The switches 9 are electrically connected to the power switch 14. Multiple sets of wires 12 are connected to the front side of the power switch 14. Each set of wires 12 has two wires. The other end of the wires 12 is connected to the heating rods 13. A protective shell 22 is installed inside the steam generating chamber 1 by welding. The power switch 14 is located inside the protective shell 22, thereby protecting the power switch 14.

[0030] When this device is needed, first connect the bus power supply to the input terminal of the switch 9, connect the output terminal of the switch 9 to the input terminal of the power switch 14 via a wire, connect the steam supply pipe to the three-way water supply pipe 701, then connect the ball valve 301 to the external water supply pipe, open the ball valve 301, and water enters the heat exchanger 4 through the three-way water inlet pipe 3. The water in the heat exchanger 4 enters the steam generator 1 through the water supply pipe 401. When the water level in the heat exchanger 4 rises, it drives the float 15 and the connecting rod 21 to rotate upward around the shaft 302. The connecting rod 21 rotates upward around the mounting base 17, causing the upper end of the connecting rod 21 to slide the piston 303 forward, gradually blocking the front end of the three-way water inlet pipe 3. This slows down the water supply speed from the three-way water inlet pipe 3 to the exchanger 4 until it stops. Next, the heating rod 13 is turned on by the power switch 14, heating the water inside the steam generator 1 to form steam. The steam then enters the steam supply pipeline through the steam outlet pipe 6 and the three-way water supply pipe 701 to supply steam to the production line. As the water in the steam generator 1 gradually decreases, the exchanger 4... Water continuously enters the steam generator 1 through the water supply pipe 401. The float ball 15 drives the connecting rod 21 to rotate downwards around the pivot 302. The upper end of the connecting rod 21 pushes the piston 303 backwards, opening the front end of the three-way water inlet pipe 3, allowing the three-way water inlet pipe 3 to replenish water into the exchanger 4 again, ensuring that the water level in the exchanger 4 is maintained within a certain range. Water is then continuously replenished into the steam generator 1 through the water supply pipe 401 to prevent the temperature inside the steam generator 1 from dropping and causing unstable steam output if too much water is added to the steam generator 1 at once. To achieve the goal of providing stable steam for enameled wire production, avoid affecting the stability of enameled wire quality, and ensure that the enameled wire is free from oxidation, the level sensor 16 monitors the water level in the exchanger 4. When the piston 303 is accidentally stuck and cannot slide, and the water level in the exchanger 4 drops to the low liquid level point, the level sensor 16 transmits a signal to the controller 8. The controller 8 controls the buzzer 1601 to turn on, and the buzzer 1601 sounds to remind the staff that water needs to be added to the exchanger 4 immediately, thereby preventing the steam generator 1 from dry burning due to lack of water.

[0031] Example 2: Based on Example 1, please refer to... Figure 1 , Figure 2 and Figure 8 A pressure gauge 601 is installed on the top of the steam generator 1, and a second valve 602 is installed at the bottom of the pressure gauge 601. The lower end of the pressure gauge 601 is connected to the steam outlet pipe 6.

[0032] During the use of the device, the controller 8 opens the second valve 602 to bring the pressure gauge 601 into contact with the steam inside the steam outlet pipe 6, thereby monitoring and controlling the steam pressure to ensure that the steam pressure does not exceed the set safety limit and avoid potential safety hazards.

[0033] Please see Figure 8 and Figure 9 The steam outlet pipe 6 is equipped with a hydrophobic and breathable membrane 18. The lower end of the steam outlet pipe 6 is connected to and connected to a drain pipe 19. Six filters 20 are embedded inside the drain pipe 19.

[0034] After steam enters the steam outlet pipe 6, the hydrophobic and breathable membrane 18 intercepts the moisture carried in the steam. The steam then enters the three-way water supply pipe 701 through the hydrophobic and breathable membrane 18, thereby reducing the moisture content in the steam and improving the quality of the steam. The intercepted moisture enters the drain pipe 19, where the filter screen 20 filters out the impurities, thereby improving the purity of the water.

[0035] Please see Figure 6 It also includes a current transformer 901, a warning light 902, and an alarm 10. Each set of circuit breakers 9 has two incoming terminals at the top and two outgoing terminals at the bottom. A current transformer 901 is installed on the incoming terminal of the circuit breaker 9. Eight warning lights 902 are installed in the upper part of the controller 8, and the warning lights 902 correspond to the current transformers 901. An alarm 10 is installed on the top of the controller 8 by means of bolt connection. The alarm 10 is electrically connected to the current transformer 901, and the current transformer 901 is electrically connected to the warning light 902.

[0036] When connecting the bus power supply to the incoming terminal of the circuit breaker 9, first pass the power line through the current transformer 901, then connect the power line to the incoming terminal of the circuit breaker 9. Connect the current transformer 901, warning light 902, and alarm 10 to the uninterruptible power supply. When the current entering the circuit breaker 9 is abnormal, the current transformer 901 will feed back the abnormal signal to the warning light 902 and alarm 10. Relevant personnel can quickly identify the abnormal circuit through the warning signals of the warning light 902 and alarm 10, so as to eliminate circuit faults, stabilize the heating power of the heating rod 13, and ensure that steam is stably generated in the steam generator box 1.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
