Description

Technical Field

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

[0002] An electrode boiler is a device that uses the current heat effect generated between electrodes and a conductive medium for heating. It is widely used in fields such as central heating and industrial production, and mainly consists of a drum, electrodes, a furnace cover, etc. When the electrodes are connected to the power supply, current passes through the electrodes and contacts the water. The water, as a conductive medium, generates heat due to its own resistance, and then heats the water to produce steam or hot water. Taking a three-phase electrode boiler as an example, three electrodes are respectively connected to three-phase power supplies to form a uniform electric field in the water, so that the water can be heated up quickly.

[0003] In the prior art, an opening is provided at the top end of the furnace cover of the electrode boiler, and a negative pressure device is connected to the opening position. The steam generated inside will be discharged through the opening at the top end of the furnace cover, so that steam-water separation can be achieved. However, during actual production, the temperature inside 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. Thus, if the negative pressure of the negative pressure device remains constant all the time, when the internal pressure of the device is large, the internal steam cannot be discharged in time, and when the internal pressure of the device is small, the negative pressure device cannot suck away the generated steam in time. Therefore, a steam-water separation device for an electrode boiler 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 background art, and then a steam-water separation device for an electrode boiler is proposed. The disclosed device of the present invention is provided with a control component. When the internal pressure of the device is large, the sliding sleeve will be forced to move upward under the action of the pressure. In this way, the connecting rod and the sliding rod can be driven to move upward, and the sliding rod will drive the wind blocking block to move upward. In this way, the gap between the wind blocking block and the air suction sleeve will increase, so that the steam can be discharged more quickly. When the internal pressure of the device is small, the gap between the wind blocking block and the air suction sleeve will decrease. In this way, without changing the output power of the negative pressure device, the negative pressure suction force at the lower end of the air suction sleeve can be increased, so that the adsorption operation can be normally completed even when the internal pressure of the device is small. The overall device has good applicability.

[0020] It should be noted that the following detailed description is exemplary 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 of ordinary skill in the technical field to which the present application belongs.

[0021] As Figures 1 - 3 As shown, an embodiment provided by the present invention: an electrode boiler steam-water separation device includes a furnace body 1, a furnace cover 2 is installed at the upper end of the furnace body 1 to close the top opening of the furnace body 1, an air duct 3 for discharging steam is arranged on the upper surface of the furnace cover 2, an exhaust pipe 4 for connecting a negative pressure device is arranged on the outer wall of the air duct 3, and a control component 5 for automatically controlling the adsorption force is arranged on the upper surface of the furnace cover 2; The control component 5 includes a support sleeve 51 for supporting the movement of the slide 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 penetrates and is slidably connected to a slide sleeve 52 for driving the movement of the transmission rod 53. A transmission rod 53 for driving the movement of the connecting rod 56 is fixedly connected to the inner wall of the slide sleeve 52, and an connecting rod 56 for transmitting motion is fixedly connected to the upper end of the transmission rod 53.

[0022] As Figures 2 - 5As shown, a cover plate 54 for closing the top opening of the air duct 3 is threadedly connected to the upper surface of the air duct 3. A sliding rod 59 for supporting a support rod 57 is inserted into the upper surface of the cover plate 54. The upper end of the sliding rod 59 is fixedly connected to the lower surface of the connecting rod 56. When the connecting rod 56 moves upward, it will drive the sliding rod 59 to move upward synchronously. A support rod 57 for driving a wind blocking block 510 to move is rotatably connected to the inner wall of the sliding rod 59. A wind blocking block 510 for controlling the magnitude of the adsorption force is fixedly connected to the lower surface of the support rod 57. When the power of the negative pressure device remains unchanged, the size of the gap between the wind blocking block 510 and the air suction sleeve 58 is negatively correlated with the adsorption force. If the size of the gap increases, the adsorption force decreases, and at the same time, the flow capacity increases. If the size of the gap decreases, the adsorption force increases, and at the same time, the flow capacity decreases. An air suction sleeve 58 is fixedly connected to the inner wall of the air duct 3. 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. A cleaning component 7 is arranged on the outer wall of the air duct 3, and an adjusting component 6 is arranged on the outer wall of the support sleeve 51.

[0023] As Figures 3 - 5 shown, the control component 5 further includes a gasket 55 for ensuring the seal of the outer wall of the sliding rod 59. The gasket 55 is fixedly connected to the lower surface of the cover plate 54. A support plate 512 for pressing the gasket 55 is fixedly connected to the inner wall of the air duct 3. The gasket 55 is inserted between the support plate 512 and the cover plate 54. By rotating the cover plate 54, it can be driven to move downward. In this way, the gasket 55 can be pressed by the opposite movement of the cover plate 54 and the support plate 512. When the gasket 55 is pressed, it will deform and fit the outer wall of the sliding rod 59 to ensure the seal when the sliding rod 59 moves up and down. The air suction sleeve 58 is set as a hollow cone with openings at both the upper and lower ends. The lower surface of the wind blocking block 510 is set as a cone, and the inclination angle is the same as the inclination angle of the inner wall of the air suction sleeve 58.

[0024] As Figure 3 、 Figure 5 and Figure 6As shown in the figure, the adjusting assembly 6 includes a sliding frame 61 for supporting the adjusting screw 62. The sliding frame 61 is fixedly connected to the upper surface of the limiting plate 65. The inner wall of the sliding frame 61 is slidably connected with a limiting block 63 for blocking the downward movement of the limiting plate 65. The upper surface of the connecting rod 56 is fixedly connected with a limiting plate 65 for restricting the up and down movement of the connecting rod 56. The upper surface of the sliding frame 61 is penetrated and threadedly connected with an adjusting screw 62 for driving the limiting block 63 to move. The limiting block 63 is rotatably connected to the outer wall of the adjusting screw 62. By rotating the adjusting screw 62, the adjusting screw 62 can be driven to move up and down, so that the limiting block 63 can be driven to move up and down. By changing the up and down position of the limiting block 63, the lowest position of the limiting plate 65 can be restricted. The lower end of the adjusting screw 62 is fixedly connected with a blocking block 64 for blocking the upward movement of the limiting plate 65. The upper surface of the sliding frame 61 is circular, and the rest of the part is semi-cylindrical. Such a setting can facilitate the operator to observe the positions of the limiting block 63 and the blocking block 64.

[0025] As Figure 3 , Figure 7 and Figure 8 shown in the figure, the cleaning assembly 7 includes a plug 71 for driving the support rod 57 to rotate. The plug 71 is fixedly connected to the upper end of the support rod 57. When the plug 71 rotates, the support rod 57 will be driven to rotate synchronously. A cleaning motor 73 for outputting power is installed on the outer wall of the air duct 3. The lower end of the output shaft of the cleaning motor 73 is fixedly connected with a transmission sleeve 74. The plug 71 is inserted into the inner wall of the transmission sleeve 74. When the transmission sleeve 74 rotates, it can drive the plug 71 to rotate. A scraping plate 77 for cleaning the windshield block 510 is fixedly connected to the outer wall of the sliding rod 59. The transmission sleeve 74 is set as a hollow cylinder. The lower surface of the transmission sleeve 74 is provided with a slot 75 adapted to the plug 71. The plug 71 can be inserted into the interior of the transmission sleeve 74 through the slot 75. The outer wall of the plug 71 is provided with a spline 72, and the inner wall of the slot 75 is provided with a keyway 76. Through the cooperation of the spline 72 and the keyway 76, the stability of the power transmission between the plug 71 and the transmission sleeve 74 can be ensured.

[0026] Working principle: During the operation of the electrode boiler, the internal pressure of the furnace body 1 changes with the working conditions. When the internal pressure increases, the steam pressure acts on the sliding sleeve 52, overcoming the elastic force of the support spring 511, causing the sliding sleeve 52 to move upward. The sliding sleeve 52 drives the transmission rod 53 and the connecting rod 56 to move upward synchronously, and then drives the sliding rod 59 to rise. The wind blocking block 510 connected to the sliding rod 59 also moves upward accordingly. Since the gap between the wind blocking block 510 and the air suction sleeve 58 is negatively correlated with the adsorption force, at this time the gap increases. When the power of the negative pressure device remains unchanged, the air suction sleeve 58 has a stronger ability to allow steam to flow through, and the steam can be discharged more quickly through the air duct 3 and the exhaust pipe 4. On the contrary, when the internal pressure of the furnace body 1 decreases, the support spring 511 pushes the sliding sleeve 52 to reset downward, driving the wind blocking block 510 to move downward, reducing the gap between the wind blocking block 510 and the air suction sleeve 58, and increasing the negative pressure suction at the lower end of the air suction sleeve 58, so that steam can be effectively adsorbed and discharged even when the internal pressure is relatively small.

[0027] If it is necessary to further optimize the steam discharge effect 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 within the sliding frame 61, the rotation of the adjustment screw 62 drives 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 to the connecting rod 56, so the initial position of the wind blocking block 510 can be controlled. 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, that is, it limits the maximum movable position of the wind blocking block 510, realizing the manual fine-tuning of the steam discharge control.

[0028] As the electrode boiler continues to operate, condensate will be generated on the outer wall of the wind blocking block 510. At this time, start the cleaning motor 73, and the output shaft of the cleaning motor 73 drives the transmission sleeve 74 to rotate. Since the plug 71 is inserted into the transmission sleeve 74 through the spline 72 and the keyway 76 on the inner wall of the transmission sleeve 74, the rotation of the transmission sleeve 74 drives the plug 71 to rotate, and then the support rod 57 drives the wind blocking block 510 to rotate. During the rotation of the wind blocking block 510, its outer wall rubs against the scraper 77 fixed on the sliding rod 59, and the scraper 77 scrapes off the condensate on the outer wall of the wind blocking block 510, preventing the condensate from being discharged together with the steam and ensuring the purity of the steam.
