Description

Technical Field

[0001] The present invention relates to the field of electrode boilers, and in particular to a steam-water separation device for electrode boilers. Background Art

[0002] An electrode boiler utilizes the thermal effect of electric current generated between electrodes and a conductive medium to generate heat. Widely used in central heating, industrial production, and other fields, it primarily consists of a boiler drum, electrodes, and a furnace cover. When the electrodes are connected to a power source, current flows through them, contacting the water. The water, acting as a conductive medium, generates heat due to its own electrical resistance, heating the water to produce steam or hot water. For example, in a three-phase electrode boiler, the three electrodes are connected to a three-phase power source, creating a uniform electric field in the water, rapidly heating it.

[0003] In the prior art, an opening is provided at the top of the electrode boiler furnace cover, and a negative pressure device is connected to the opening. The steam generated inside the furnace cover is discharged through the opening at the top of the furnace cover, thereby achieving water vapor separation. However, in actual production, the internal temperature of the electrode boiler is not stable. Adding cold water or discharging hot water will cause the internal pressure and steam volume of the electrode boiler to decrease. In this way, if the negative pressure of the negative pressure device remains unchanged, when the internal pressure of the device is high, the internal steam will not be able to be discharged in time, and when the internal pressure of the device is low, the negative pressure device will not be able to absorb the produced steam in time. Therefore, an electrode boiler steam-water separation device is proposed to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems raised in the above-mentioned background technology, and then propose an electrode boiler steam-water separation device. The device disclosed by the present invention is provided with a control component. When the internal pressure of the device is relatively high, the sliding sleeve will be forced to move upward under the action of the pressure, thereby driving the connecting rod and the sliding rod to move upward. The sliding rod will drive the windshield block to move upward, thereby increasing the gap between the windshield block and the air suction sleeve, thereby guiding the steam discharge faster. When the internal pressure of the device is relatively low, the gap between the windshield block and the air suction sleeve will be reduced. In this way, when the output power of the negative pressure device remains unchanged, the size of the negative pressure suction force at the lower end of the air suction sleeve can be increased. In this way, the adsorption operation can be completed normally even when the internal pressure of the device is relatively low. The overall applicability of the device is good.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

When the windshield rotates, it will rub against the scraper, so that the outer wall of the windshield can be cleaned by the scraper, which can prevent the condensed water from being discharged along with the steam.

DETAILED DESCRIPTION

[0030] It should be noted that the following detailed description is illustrative and is intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present application belongs.

[0031] like Figure 1-Figure 3 As shown, an embodiment of the present invention provides an electrode boiler steam-water separation device, comprising a furnace body 1, a furnace cover 2 for closing the top opening of the furnace body 1 is installed on the upper end of the furnace body 1, an air duct 3 for discharging steam is provided on the upper surface of the furnace cover 2, an exhaust pipe 4 for connecting to a negative pressure device is provided on the outer wall of the air duct 3, and a control component 5 for automatically controlling the adsorption force is provided on the upper surface of the furnace cover 2;

[0032] The control component 5 includes a support sleeve 51 for supporting the movement of the sliding sleeve 52. The support sleeve 51 is fixedly connected to the upper surface of the furnace cover 2. The lower surface of the support sleeve 51 passes through and is slidably connected to the sliding sleeve 52 for driving the transmission rod 53 to move. The inner wall of the sliding sleeve 52 is fixedly connected to the transmission rod 53 for driving the connecting rod 56 to move. The upper end of the transmission rod 53 is fixedly connected to the connecting rod 56 for transmitting motion.

[0033] like Figure 2-Figure 5As shown, the upper surface of the air duct 3 is threadedly connected with a cover plate 54 for closing the top opening of the air duct 3. The upper surface of the cover plate 54 is plugged with a slide bar 59 for lifting the support rod 57. The upper end of the slide bar 59 is fixedly connected to the lower surface of the connecting rod 56. When the connecting rod 56 moves upward, it will drive the slide bar 59 to move upward synchronously. The inner wall of the slide bar 59 is rotatably connected to the support rod 57 for driving the windshield block 510 to move. The lower surface of the support rod 57 is fixedly connected with the windshield block 510 for controlling the size of the adsorption force. When the power of the negative pressure device remains unchanged, the gap between the windshield block 510 and the suction sleeve 58 There is a negative correlation between the size of the gap and the adsorption force. If the gap size increases, the adsorption force decreases and the flow capacity increases. If the gap size decreases, the adsorption force increases and the flow capacity decreases. The inner wall of the air guide tube 3 is fixedly connected with a suction sleeve 58. The upper surface of the sliding sleeve 52 is elastically connected to the inner wall of the support sleeve 51 through a support spring 511. The support spring 511 will always support the sliding sleeve 52 downward. When the internal pressure of the device decreases, the support spring 511 will push the sliding sleeve 52 to move downward and reset. The outer wall of the air guide tube 3 is provided with a cleaning component 7, and the outer wall of the support sleeve 51 is provided with an adjustment component 6.

[0034] like Figure 3-Figure 5 As shown, the control component 5 also includes a sealing gasket 55 for ensuring the sealing of the outer wall of the sliding rod 59. The sealing gasket 55 is fixedly connected to the lower surface of the cover plate 54. The inner wall of the air guide tube 3 is fixedly connected to a support plate 512 for squeezing the sealing gasket 55. The sealing gasket 55 is inserted in the middle position of the support plate 512 and the cover plate 54. It can be driven to move downward by rotating the cover plate 54. In this way, the sealing gasket 55 can be squeezed by the opposite movement of the cover plate 54 and the support plate 512. The sealing gasket 55 will be deformed and fit the outer wall of the sliding rod 59 when squeezed, thereby ensuring the sealing of the sliding rod 59 when it moves up and down. The suction sleeve 58 is set to a hollow cone with upper and lower openings. The lower surface of the windshield block 510 is set to a cone and the inclination angle is the same as the inclination angle of the inner wall of the suction sleeve 58.

[0035] like Figure 3 、 Figure 5 and Figure 6The upper end of the adjusting screw 62 is fixedly connected to a stopper 64 for stopping the limit plate 65 from moving upward. The upper surface of the sliding frame 61 is set to be circular, and the other parts are set to be semi-cylindrical. Such a setting can facilitate the operator to observe the positions of the limit block 63 and the stopper 64.

[0036] like Figure 3 、 Figure 7 and Figure 8 The cam 75 is fixed on the top of the support rod 57 so that the cam 75 can rotate with the help of the clutch pedal 72. When the cam 75 is rotated, the clutch pedal 72 is rotated and the clutch pedal 72 is rotated.

[0037] Operating Principle: During operation of an electrode boiler, the internal pressure of the furnace body 1 fluctuates with operating conditions. When internal pressure increases, steam pressure acts on the sliding sleeve 52, overcoming the elastic force of the support spring 511 and causing the sliding sleeve 52 to move upward. The sliding sleeve 52 drives the transmission rod 53 and connecting rod 56 upward, which in turn drives the sliding rod 59 upward, and the windshield 510 connected to the sliding rod 59 also moves upward. Because the gap between the windshield 510 and the suction sleeve 58 is negatively correlated with the suction force, the gap increases. While the power of the negative pressure device remains unchanged, the suction sleeve 58's steam flow capacity is enhanced, allowing steam to be discharged more quickly through the air duct 3 and exhaust pipe 4. Conversely, when the internal pressure of the furnace body 1 decreases, the support spring 511 pushes the sliding sleeve 52 downward, driving the windshield 510 downward. This reduces the gap between the windshield 510 and the suction sleeve 58, increasing the negative pressure suction at the lower end of the suction sleeve 58. This allows steam to be effectively adsorbed and discharged even when the internal pressure is low.

[0038] If the steam emission effect needs to be further optimized according to the actual production environment, it can be adjusted through the adjustment component 6. Rotate the adjustment screw 62. Since the adjustment screw 62 is threadedly connected to the sliding frame 61, and the limit block 63 is rotatably connected to the outer wall of the adjustment screw 62 and slides in the sliding frame 61, the rotation of the adjustment screw 62 will drive the limit block 63 to move up and down. The position change of the limit block 63 can limit the lowest position of the limit plate 65, and the limit plate 65 is fixed on the connecting rod 56, so it can control the initial position of the wind shield 510. At the same time, the stop block 64 at the lower end of the adjustment screw 62 can limit the upward movement of the limit plate 65, thereby limiting the maximum movable position of the wind shield 510, thereby realizing manual fine-tuning of the steam emission control.

[0039] As the electrode boiler continues to operate, condensate forms on the outer wall of the windshield 510. At this point, the cleaning motor 73 is activated, and its output shaft drives the transmission sleeve 74 to rotate. Because the insert 71 is inserted into the transmission sleeve 74 via the spline 72 that engages the keyway 76 on the inner wall of the transmission sleeve 74, the rotation of the transmission sleeve 74 drives the insert 71 to rotate, which in turn causes the support rod 57 to rotate the windshield 510. As the windshield 510 rotates, its outer wall rubs against the scraper 77 fixed to the slide bar 59. The scraper 77 scrapes away the condensate on the outer wall of the windshield 510, preventing it from being discharged along with the steam and ensuring the purity of the steam.
