Description

Technical Field

[0001] The present application relates to the technical field of boiler water seal tanks, and in particular to an automatic water replenishing device for a boiler water seal tank. Background Art

[0002] The automatic water replenishment system for boiler water seal tanks is a device specifically designed to automatically monitor and replenish the water level in the boiler water seal tank. Its operating principle is primarily based on a float valve or water level sensor. Specifically, when the water level in the water seal tank drops, the float valve (or water level sensor) detects this change and triggers the water replenishment mechanism. A water replenishment pump or other water replenishment device then activates, pumping water into the water seal tank through the replenishment pipe until the water level returns to a preset safe level. Once the water level reaches the set value, the water replenishment system automatically stops and waits for the next water replenishment request.

[0003] The sensors and electronic on / off devices used to sense water levels are easily damaged due to being in a high-temperature and corrosive environment for a long time, which leads to failure of the automatic water replenishment function, causing the boiler to lose its water seal and gas leakage.

[0033] The embodiment of the present application provides a boiler water seal tank automatic water filling device, such as Figure 1 As shown, the boiler water seal tank automatic water replenishment device may include a water seal tank 1, a connecting pipe 11, a sedimentation tank 12, a mounting base 13, a drive motor 2, a turbine 21, a water replenishment pipe 22, a water level monitoring component, a cleaning component 6 and a filtering component 8;

[0034] Among them, the connecting pipe 11 is fixedly installed at the bottom of the outer wall of the water seal tank 1 and is connected to the water seal tank 1. The sedimentation tank 12 is fixedly installed at one end of the connecting pipe 11 and is connected to the connecting pipe 11. The connecting pipe 11 connects the water seal tank 1 and the sedimentation tank 12, so that the water levels on both sides remain synchronized, and the depth of the sedimentation tank 12 is greater than the depth of the water seal tank 1, and no backflow will occur after impurities settle into the sedimentation tank 12.

[0035] The mounting seat 13 is fixedly mounted on the outer wall of the water seal tank 1, the drive motor 2 is fixedly mounted on the mounting seat 13, the turbine 21 is fixedly mounted on the mounting seat 13, and is connected to the output end of the drive motor 2. The water supply pipe 22 is fixedly mounted between the turbine 21 and the water seal tank 1 and passes through the water seal tank 1. The water supply pipe 22 connects the water source (not shown) and the water seal tank 1. The drive motor 2 can drive the turbine 21 to rotate so that the water level can be replenished.

[0036] Please combine Figure 2-Figure 4 For reference, the water level monitoring component is arranged in the sedimentation tank 12 to detect the water level so as to determine whether the water seal tank 1 needs to be supplemented with water. The water level of the sedimentation tank 12 is monitored by the water level detection component to thereby monitor the water level in the water seal tank 1.

[0037] Please combine Figure 5 and Figure 6 For reference, the cleaning component 6 is arranged in the water seal tank 1, and is used to clean impurities settled in the water seal tank 1. The impurities may affect the smoothness of the system. By cleaning them in time, the waterway can be kept smooth.

[0038] like Figure 7 As shown, the filter assembly 8 is arranged in the water seal tank 1 and is adapted to the water supply pipe 22 for filtering the replenished water. The water quality conditions in the water seal tank 1 can be ensured through preliminary filtration.

[0039] Specifically, when the boiler is working normally, the water level in the water seal tank 1 can be monitored by the water level monitoring component. Secondly, the automatic water replenishment is achieved by turning the power on and off of the driving motor 2. The ash, coke powder and other materials settled at the bottom of the water seal tank 1 are cleaned to the sedimentation tank 12 by the cleaning component 6. Finally, the water quality in the water seal tank 1 can be kept clean through filtration through the filtering component 8 to avoid system blockage. The sedimentation tank 12 is connected to the water seal tank 1. By monitoring the water level of the sedimentation tank 12, not only the water seal tank 1 can be monitored, but also the components can be prevented from being corroded, thereby increasing the service life of the system and saving the use cost. In addition, it is safer to clean the sediment in the sedimentation tank 12, which can protect the safety of the operator.

[0040] Please continue to combine Figure 2-Figure 4 For reference, in an exemplary embodiment, the water level monitoring assembly may include a float 4 and a switch assembly 3. The float 4 is disposed in the sedimentation tank 12, and the switch assembly 3 is disposed on the float 4 and adapted to the drive motor 2.

[0041] Specifically, the float 4 can float on the water surface in the sedimentation tank 12. As the water level in the water seal tank 1 changes, the water level in the sedimentation tank 12 will also change synchronously, driving the float 4 to move up and down, thereby driving the on-off component 3 to move and control the opening and closing of the drive motor 2.

[0042] Furthermore, the on-off assembly 3 may include a guide column 31 , a fixing ring 36 , a positioning mechanism, a on-off ring 33 , a mounting plate 34 , a guide rod 1 35 , an upper limit plate 351 , a lower limit plate 352 and a counterweight ring 41 . Among them, the guide column 31 is fixedly installed on the outer wall of the sedimentation tank 12, the fixed ring 36 is fixedly mounted on the guide column 31 and is electrically connected to the drive motor 2, the positioning mechanism is set on the guide column 31, the on-off ring 33 is slidably mounted on the guide column 31 and is fixedly connected to the positioning mechanism, the movable ring 341 is slidably mounted on the guide column 31, the mounting plate 34 is L-shaped and fixedly mounted on the movable ring 341, the guide rod 1 35 is fixedly mounted on the end of the mounting plate 34 away from the movable ring 341, the upper limit plate 351 is fixedly mounted on the guide rod 1 35, the lower limit plate 352 is fixedly mounted on the guide rod 1 35 and is located on the lower side of the upper limit plate 351, the counterweight ring 41 is slidably mounted on the guide rod 1 35 and is located between the upper limit plate 351 and the lower limit plate 352, and is fixedly connected to the floating ring 4.

[0043] Specifically, when the water level is at the upper limit, the float 4 drives the counterweight ring 41 to slide along the guide rod 35, and contacts the upper limit plate 351 to lift the mounting plate 34 to the top, driving the movable ring 341 to move upward, and driving the positioning mechanism to fix the on-off ring 33 in the off position, the on-off ring 33 is separated from the fixed ring 36, and the drive motor 2 stops moving. The opposite sides of the on-off ring 33 and the fixed ring 36 are both provided with conductive mechanisms, and the working principle and connection method of the conductive mechanisms are existing mature technologies, which will not be elaborated here.

[0044] Furthermore, the positioning mechanism may include a positioning hole 5, a positioning ring 32, a mounting hole 51, a positioning ball 53 and a spring 52; wherein, there are several positioning holes 5, which are opened on the guide column 31 and distributed in a circular array; the positioning ring 32 is slidably mounted on the guide column 31 and fixedly connected to the mounting plate 34; there are several mounting holes 51, which are opened on the positioning ring 32 and correspond to the positioning holes 5; the positioning ball 53 is movably installed in the mounting hole 51 and adapted to the positioning hole 5; the spring 52 is fixedly installed between the mounting hole 51 and the positioning ball 53.

[0045] Specifically, when no external force is applied, in the mounting hole 51 of the positioning ring 32, spring 1 52 pushes the positioning ball 53 outward, and the positioning ball 53 can be stuck in the positioning hole 5 on the guide column 31, thereby fixing the position of the on-off ring 33, and then controlling the opening and closing state of the drive motor 2. When subjected to external force, the positioning ball 53 squeezes the spring 1 52 and enters the mounting hole 51, and then the positioning ring 32 can slide along the guide column 31 until the positioning ball 53 falls into another row of positioning holes 5.

[0046] Please continue to combine Figure 5 、 Figure 6 and Figure 8For reference, in an exemplary embodiment, the cleaning assembly 6 may include a reciprocating screw 61, a second guide rod 62, a guide block 63, a drive mechanism, and a cleaning mechanism. The reciprocating screw 61 is rotatably mounted on the top of the water seal tank 1, the second guide rod 62 is fixedly mounted on the top of the water seal tank 1 and symmetrically arranged with the reciprocating screw 61, two guide blocks 63 are provided, one of which is slidably mounted on the reciprocating screw 61 and the other is slidably mounted on the second guide rod 62. The drive mechanism is provided on the drive motor 2, and the cleaning mechanism is provided on the lower end surface of the guide block 63.

[0047] Specifically, the reciprocating screw 61 rotates under the action of the driving mechanism, driving the guide block 63 to reciprocate along the direction of the guide rod 2 62, wherein the cleaning mechanism at the bottom of the guide block 63 contacts the bottom of the water seal tank 1, and can clean the impurities settled at the bottom to the connecting pipe 11 during the reciprocating motion, and enter the sedimentation tank 12 through the connecting pipe 11 for collection.

[0048] Furthermore, the driving mechanism may include a transmission wheel 23, a driven wheel 24, and a synchronous belt 25. The transmission wheel 23 is fixedly mounted on the output end of the driving motor 2, the driven wheel 24 is fixedly mounted on the end of the reciprocating screw 61 passing through the water seal groove 1, and the synchronous belt 25 is mounted on the transmission wheel 23 and the driven wheel 24.

[0049] Specifically, when the water level reaches the lower limit, the drive motor 2 starts to replenish water, and at the same time can drive the transmission wheel 23 to rotate, and then drive the driven wheel 24 to rotate through the synchronous belt 25. The driven wheel 24 is fixedly connected to the reciprocating screw 61 to drive the cleaning mechanism to work.

[0050] In some embodiments, the cleaning mechanism may include a mounting rod 7, a hinge 71, and a scraper 72. Two mounting rods 7 are provided, each fixedly mounted on the lower end surface of the two guide blocks 63; two hinges 71 are provided, each symmetrically fixedly mounted on the mounting rod 7 near the bottom of the side wall of the sedimentation tank 12; and the scraper 72 is fixedly mounted on the hinge 71 and is made of a lightweight material.

[0051] Specifically, when the cleaning mechanism moves toward the sedimentation tank 12, the contact surface between the scraper 72 and the mounting rod 7 acts as a limit, restricting the scraper 72 from rotating along the hinge 71. At this time, impurities at the bottom of the water seal tank 1 can be pushed into the sedimentation tank 12. When it moves in the opposite direction, the scraper 72 can rotate to a certain angle along the hinge 71 under the damping effect of water, thereby breaking contact with the bottom of the water seal tank 1 and avoiding bringing impurities back.

[0052] In some embodiments, an inclined portion 721 is provided at the bottom of the scraper 72 .

[0053] It can be understood that the inclined portion 721 can better clean the sediment.

[0054] Please combine Figure 5 and Figure 7 For reference, in an exemplary embodiment, the filter assembly 8 may include a filter screen 82 and a vibration mechanism. The filter screen 82 is arranged at one end of the water supply pipe 22 extending into the water seal tank 1, and the vibration mechanism is arranged on the filter screen 82.

[0055] Specifically, the vibration mechanism can vibrate the filter 82 to remove impurities attached to the filter 82 through vibration.

[0056] Furthermore, the vibration mechanism may include a slide rail 81, a second spring 83, a connecting rod 84, a push plate 85, and an eccentric wheel 86. The slide rail 81 is fixedly mounted on the inner wall of the water seal tank 1, and the filter screen 82 is slidably connected to the slide rail 81. The second spring 83 is fixedly mounted between the slide rail 81 and the filter screen 82. The connecting rod 84 is L-shaped and fixedly mounted on the filter screen 82, corresponding to the position of the reciprocating screw 61. The push plate 85 is fixedly mounted on the end of the connecting rod 84 away from the filter screen 82. The eccentric wheel 86 is fixedly sleeved on the reciprocating screw 61 and adapted to the push plate 85.

[0057] Specifically, when the reciprocating screw 61 rotates, it drives the eccentric wheel 86 to rotate, and intermittently pushes the push plate 85 to drive the filter screen 82 to slide in the slide rail 81. At the same time, the filter screen 82 is reset under the action of the spring 83, thereby achieving the reciprocating vibration effect.

[0058] The boiler water seal tank automatic water replenishing device proposed in the embodiment of the present application monitors the water level in the water seal tank 1 through the water level monitoring component, and then automatically switches the power of the drive motor 2 on and off according to the water level through the float ring 4 and the on-off component 3 to achieve automatic water replenishment, and then cleans the ash, coke powder and other materials settled at the bottom of the water seal tank 1 to the sedimentation tank 12 through the cleaning component 6. Finally, through the filtering component 8 and the vibration mechanism, the water quality in the water seal tank 1 can be kept clean after filtration to avoid system blockage. The sedimentation tank 12 is connected to the water seal tank 1. By monitoring the water level of the sedimentation tank 12, not only can the water seal tank 1 be monitored, but also the components can be prevented from being corroded, thereby increasing the service life of the system and saving the use cost. In addition, it is safer to clean the sediment in the sedimentation tank 12, which can protect the safety of the operator.
