Description

Technical Field

[0001] This invention relates to the field of water treatment technology, and in particular to a boiler drum inlet water deoxygenation and purification system. Background Technology

[0002] A boiler drum is a pressure vessel installed above a steam boiler. It is typically used to store and regulate the steam pressure generated by the boiler. To maintain the water level inside the boiler, a sufficient amount of water needs to be injected into the boiler drum. To prevent the water entering the boiler drum from corroding the metal inside the boiler drum, the water needs to be deoxygenated and purified.

[0003] Current methods for treating boiler drum water mostly involve adding sufficient chemical deoxidizers to the feed water. This causes the oxygen and carbon dioxide in the feed water to react with the chemical deoxidizers to form non-volatile compounds. These compounds and impurities are then filtered through a screen. While this method can remove oxygen and carbon dioxide from the feed water, during application, compounds and impurities often accumulate on the filter screen. This requires regular cleaning by staff to prevent the accumulated compounds and impurities from clogging the filter pores and hindering its normal filtering function. This process is not only time-consuming and labor-intensive but also significantly delays the treatment progress of the boiler drum feed water. Therefore, we propose a boiler drum feed water deoxygenation and purification system. Summary of the Invention

[0004] To address the technical problem of poor performance of existing boiler drum water treatment equipment, this invention provides a boiler drum water deoxygenation and purification system.

[0005] This invention is achieved using the following technical solution: a boiler drum water deoxygenation and purification system, comprising a treatment box, wherein the treatment box has a treatment chamber, a drainage chamber and a loading trough, a filter screen is slidably connected inside the treatment chamber, a discharge port is provided on the inner wall between the treatment chamber and the loading trough, a sealing block for sealing the discharge port is slidably connected inside the loading trough, a connecting component for connecting the sealing block is provided on the filter screen, a drain outlet is provided on the inner wall between the treatment chamber and the drainage chamber, a baffle for sealing the drain outlet is slidably connected inside the drain outlet, a water inlet pipe communicating with the treatment chamber is connected to the top of the treatment box, and a drain pipe communicating with the drainage chamber is connected to the end of the treatment box. Through the water inlet pipe, boiler drum water can be transported to the interior of the treatment chamber, and by opening a valve, the water inside the drainage chamber can be transported to the boiler drum through the drain pipe.

[0006] As a further improvement to the above solution, a valve is installed on the drain pipe, and a feeding valve connected to the treatment chamber is installed on the top side of the treatment box. Through the feeding valve, a sufficient amount of chemical deoxidizer can be added into the interior of the treatment chamber. The chemical deoxidizer entering the treatment chamber will cause the oxygen and carbon dioxide in the boiler drum feed water to react with the chemical deoxidizer to generate non-volatile compounds.

[0007] As a further improvement to the above solution, the connecting assembly includes a connecting block, a sliding groove, a sliding block, and a connecting block. The connecting block is fixed on the side of the filter screen near the outlet. The sliding groove is formed at the end of the connecting block near the outlet. The sliding block slides inside the sliding groove. The connecting block is slidably inserted inside the sliding groove. The end of the connecting block located inside the sliding groove is fixed to the sliding block. The closing block located inside the outlet has a sliding hole. The end of the connecting block located outside the sliding groove passes through the sliding hole and is fixed with a fixing block. A driving sleeve is embedded in the top of the filter screen. A lead screw passes through the internal thread of the driving sleeve. A connecting plate is slidably connected inside the drainage chamber. Multiple connecting blocks with their other ends fixed to a stop block are fixed on the connecting plate. A threaded sleeve is embedded in the connecting plate. The internal thread of the threaded sleeve... A screw is inserted through the device, and a gear is fixedly sleeved on the outer wall of the screw below the connecting plate. A sliding groove is opened on the inner wall between the drainage chamber and the loading tank. A rack plate that meshes with the gear slides through the sliding groove. A push plate that slides inside the loading tank is provided on the side of the sealing block away from the treatment chamber. The end of the rack plate located inside the loading tank is fixed on the push plate. Multiple return springs are fixed on the side of the push plate away from the sealing block. A support plate is fixed on the inner wall of the loading tank. The end of the return spring away from the push plate is fixed on the support plate. Through the operation of the connecting assembly, the treated water in the treatment chamber can be transported to the interior of the drainage chamber, and the compounds and impurities in the treatment chamber can be discharged. This can promote the thorough mixing of the water in the treatment chamber with the chemical deoxidizer.

[0008] As a further improvement to the above solution, the length of the linkage block is greater than the depth of the slide groove, the length of the slider is greater than the width of the slide groove opening, and the diameter of the fixed block is greater than the diameter of the sliding hole. By using a slider whose length is greater than the width of the slide groove opening, the slider can be prevented from detaching from the slide groove. By using a fixed block whose diameter is greater than the diameter of the sliding hole, when the linkage block is reset, the closing block can be pulled to perform a reset displacement, thereby causing the closing block to close the outlet.

[0009] As a further improvement to the above solution, a transition hole is provided on the inner wall between the processing chamber and the loading tank. One end of the lead screw is rotatably connected to the inner wall of the processing chamber, and the other end of the lead screw extends through the transition hole to the interior of the loading tank. The outer wall of the lead screw located outside the processing chamber is not threaded. A sealing ring is fixed to the inner wall of the outlet, sliding hole, drain outlet and the transition hole. The lead screw can rotate flexibly through the transition hole, and the sealing ring can increase the sealing performance of the equipment.

[0010] As a further improvement to the above solution, a motor is fixed to the inner wall of the loading groove, and the end of the lead screw located inside the loading groove is connected to the output end of the motor. The motor can drive the lead screw to rotate.

[0011] As a further improvement to the above solution, a mounting base is slidably connected inside the loading tank. A receiving box corresponding to the discharge port is provided above the mounting base. A drive column is rotatably connected to the inner wall of the top of the loading tank. A bevel gear one is fixedly sleeved on the outer wall of the drive column. A bevel gear two that meshes with bevel gear one is fixedly sleeved on the outer wall of the lead screw. A drive plate one is fixed at the bottom end of the lead screw. A drive plate two is hinged to the movable end of drive plate one. A drive plate three fixed on the mounting base is hinged to the movable end of drive plate two. Through the operation of the above components, the discharged compounds and impurities can be received, the compounds and impurities inside the receiving box can be leveled, and the capacity of the receiving box can be increased.

[0012] As a further improvement to the above solution, the inner wall of the bottom of the mounting base is provided with multiple positioning grooves, and a positioning block fixed on the receiving box is slidably connected inside the positioning groove. Through the cooperation of the positioning groove and the positioning block, the stability of the receiving box can be improved.

[0013] As a further improvement to the above solution, a guide groove is provided on the inner wall of the bottom of the loading groove. Multiple guide blocks fixed on the mounting base are slidably connected inside the guide groove. Through the sliding cooperation of the guide groove and the guide blocks, the displaced mounting base and receiving box can be guided, avoiding the mounting base and receiving box from shifting during the displacement process, and improving the stability of the mounting base and receiving box.

[0014] As a further improvement to the above solution, the outer side of the processing box is hinged with a first movable door and a second movable door. A second sealing ring is installed on the outer side of the first movable door and the second movable door. The first movable door corresponds to the processing chamber, and the second movable door corresponds to the drainage chamber. By opening the first movable door and the second movable door, the user can easily inspect and maintain the components inside the processing box. The second sealing ring can increase the sealing performance of the equipment.

[0027] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] Example 1:

[0029] Combination Figure 1 This embodiment of a boiler drum water deaeration and purification system includes a treatment box 1. The treatment box 1 has a treatment chamber 2, a drainage chamber 3, and a loading trough 4. A filter screen 5 is slidably connected inside the treatment chamber 2. An outlet 6 is provided on the inner wall between the treatment chamber 2 and the loading trough 4. A sealing block 7 for sealing the outlet 6 is slidably connected inside the loading trough 4. A connecting component for connecting the sealing block 7 is provided on the filter screen 5. A drain outlet 12 is provided on the inner wall between the treatment chamber 2 and the drainage chamber 3. A baffle 13 for sealing the drain outlet 12 is slidably connected inside the drain outlet 12. A water inlet pipe 19 communicating with the treatment chamber 2 is connected to the top of the treatment box 1. A drain pipe 20 communicating with the drainage chamber 3 is connected to the end of the treatment box 1. A valve is installed on the drain pipe 20. A feeding valve communicating with the treatment chamber 2 is installed on the top side of the treatment box 1.

[0030] The implementation principle of the boiler drum feed water deoxygenation and purification system in this embodiment is as follows: Boiler drum feed water is transported to the treatment chamber 2 via the inlet pipe 19. A sufficient amount of chemical deoxidizer is added to the treatment chamber 2 via the feeding valve. The chemical deoxidizer entering the treatment chamber 2 reacts with the oxygen and carbon dioxide in the boiler drum feed water to generate non-volatile compounds. After the boiler drum feed water in the treatment chamber 2 is treated, the displacement of the filter screen 5 pushes the compounds and impurities inside the treatment chamber 2 to move. When the compounds and impurities pass through the baffle 13, and the filter screen 5 is located between the compounds and the baffle 13, the baffle 13 is displaced. When the baffle 13 is disengaged from the drain outlet 12, the boiler drum water that has been processed inside the processing chamber 2 will enter the drain chamber 3 through the drain outlet 12. Then the valve can be opened, and the water inside the drain chamber 3 can be transported to the boiler drum through the drain pipe 20. By operating the connecting components, the sealing block 7 can be displaced. When the sealing block 7 opens the outlet 6, the compounds and impurities pushed by the filter screen 5 will be discharged through the outlet 6.

[0031] Example 2:

[0032] Combination Figure 2 and Figure 4This embodiment, based on embodiment 1, further improves upon the following: the connecting assembly includes a connecting block 31, a sliding groove, a slider, and a connecting block 9. The connecting block 31 is fixed to the side of the filter screen 5 near the outlet 6. The sliding groove is opened at one end of the connecting block 31 near the outlet 6. The slider slides inside the sliding groove. The connecting block 9 is slidably inserted inside the sliding groove. The end of the connecting block 9 located inside the sliding groove is fixed to the slider. The closing block 7 located inside the outlet 6 has a sliding hole 8. The end of the connecting block 9 located outside the sliding groove passes through the sliding hole 8 and is fixed with a fixing block. A driving sleeve 10 is embedded in the top of the filter screen 5, and the internal threads of the driving sleeve 10 are threaded through it. A lead screw 11 is provided. A connecting plate 14 is slidably connected inside the drainage chamber 3. Multiple connecting blocks with their other ends fixed to the stop block 13 are fixed on the connecting plate 14. A threaded sleeve 15 is embedded in the connecting plate 14. A screw 16 passes through the internal thread of the threaded sleeve 15. A gear is fixedly sleeved on the outer wall of the screw 16 below the connecting plate 14. A sliding groove is provided on the inner wall between the drainage chamber 3 and the loading groove 4. A rack plate 17 that meshes with the gear slides through the sliding groove. A push plate 18 that slides inside the loading groove 4 is provided on the side of the sealing block 7 away from the processing chamber 2. The end of the rack plate 17 located inside the loading groove 4 is fixed to the push plate 18. Multiple return springs are fixed to the side of the push plate 18 away from the closing block 7. A support plate is fixed to the inner wall of the loading groove 4. The end of the return spring away from the push plate 18 is fixed to the support plate. By rotating the lead screw 11, the filter screen 5 can be driven to move through the threaded engagement between the lead screw 11 and the drive sleeve 10, which in turn drives the connecting block 31 and the linkage block 9 to move. When the linkage block 9 contacts the push plate 18 and pushes the push plate 18 to move, it will drive the rack plate 17 to move. The moving rack plate 17 will drive the gear to rotate. At this time, the rotating gear will drive the screw 16 to rotate. The threaded engagement with the sleeve 15 causes the sleeve 15 and the connecting plate 14 to move vertically. At this time, the vertically moving connecting plate 14 will cause the connecting block and the stop block 13 to move. When the connecting block 31 contacts the closing block 7, the displaced connecting block 31 will push the closing block 7 to move, causing the closing block 7 to open the outlet 6. When the chemical deoxidizer is added into the treatment chamber 2, the intermittent reciprocating rotation of the screw 11 will cause the filter screen 5 to move back and forth. At this time, the back and forth moving filter screen 5 will agitate the water inside the treatment chamber 2, thereby promoting the water inside the treatment chamber 2 to mix fully with the chemical deoxidizer.

[0033] The length of the linkage block 9 is greater than the depth of the slide groove, the length of the slider is greater than the width of the slide groove opening, and the diameter of the fixed block is greater than the diameter of the slide hole 8. By using a slider whose length is greater than the width of the slide groove opening, the slider can be prevented from detaching from the slide groove. By using a fixed block whose diameter is greater than the diameter of the slide hole 8, when the linkage block 9 is reset, the closing block 7 can be pulled to perform a reset displacement, thereby causing the closing block 7 to close the discharge port 6.

[0034] A transition hole is provided on the inner wall between the processing chamber 2 and the loading tank 4. One end of the lead screw 11 is rotatably connected to the inner wall of the processing chamber 2, and the other end of the lead screw 11 extends through the transition hole to the interior of the loading tank 4. The outer wall of the lead screw 11 located outside the processing chamber 2 is not threaded. The outlet 6, the sliding hole 8, the drain outlet 12 and the inner wall of the transition hole are all fixed with a sealing ring. The lead screw 11 can rotate flexibly through the transition hole, and the sealing ring can increase the sealing performance of the equipment.

[0035] A motor is fixed to the inner wall of the loading slot 4. The motor is a forward and reverse stepper motor. The end of the lead screw 11 located inside the loading slot 4 is connected to the output end of the motor. The motor can drive the lead screw 11 to rotate.

[0036] Example 3:

[0037] Combination Figure 3 , Figure 5 , Figure 6 and Figure 7 This embodiment, based on embodiment 7, further improves upon the following: a mounting base 21 is slidably connected inside the loading slot 4; a receiving box 22 corresponding to the outlet 6 is provided above the mounting base 21; a drive column 23 is rotatably connected to the inner wall of the top of the loading slot 4; a bevel gear 27 is fixedly sleeved on the outer wall of the drive column 23; a bevel gear 27 meshing with the bevel gear 27 is fixedly sleeved on the outer wall of the lead screw 11; a drive plate 24 is fixedly fixed at the bottom end of the lead screw 11; a drive plate 25 is hinged to the movable end of the drive plate 24; and a drive plate 26 fixed on the mounting base 21 is hinged to the movable end of the drive plate 25. When the compound and impurities pushed by the filter screen 5 enter the outlet 6, they enter the interior of the outlet 6. The compounds and impurities will fall into the receiving box 22. The receiving box 22 can then receive the discharged compounds and impurities. When the lead screw 11 rotates, it will drive the bevel gear 2 to rotate. Through the meshing of the bevel gear 2 and the first bevel gear 27, the drive column 23 will rotate. The rotating drive column 23 will drive the first drive plate 24 to deflect, and drive the second drive plate 25 and the third drive plate 26 to deflect, causing the receiving box 22 to reciprocate horizontally. The reciprocating horizontal displacement of the receiving box 22 will cause the compounds and impurities inside the receiving box 22 to shake, thereby leveling the compounds and impurities inside the receiving box 22 and increasing the capacity of the receiving box 22.

[0038] The inner wall of the bottom of the mounting base 21 is provided with multiple positioning grooves. The positioning block 28, which is fixed on the receiver box 22, is slidably connected inside the positioning groove. The stability of the receiver box 22 can be improved by the cooperation of the positioning groove and the positioning block 28.

[0039] The inner wall at the bottom of the loading slot 4 is provided with a guide slot 30. Multiple guide blocks 29 fixed on the mounting base 21 are slidably connected inside the guide slot 30. Through the sliding cooperation between the guide slot 30 and the guide blocks 29, the displaced mounting base 21 and receiving box 22 can be guided to avoid the mounting base 21 and receiving box 22 from shifting during the displacement process, thereby improving the stability of the mounting base 21 and receiving box 22.

[0040] The outer side of the treatment chamber 1 is hinged with a first movable door 32 and a second movable door 33. A second sealing ring is installed on the outer side of the first movable door 32 and the second movable door 33. The first movable door 32 corresponds to the treatment chamber 2, and the second movable door 33 corresponds to the drainage chamber 3. By opening the first movable door 32 and the second movable door 33, the user can easily inspect and maintain the components inside the treatment chamber 1. The second sealing ring can increase the sealing performance of the equipment.

[0041] Working Principle: Boiler drum feed water is transported to the treatment chamber 2 via inlet pipe 19. Sufficient chemical deoxidizer is added to the treatment chamber 2 via the feeding valve. The chemical deoxidizer entering the treatment chamber 2 reacts with the oxygen and carbon dioxide in the boiler drum feed water to form non-volatile compounds. When the chemical deoxidizer is added to the treatment chamber 2, the intermittent forward and reverse rotation of the motor drives the lead screw 11 to reciprocate intermittently. This intermittent reciprocating rotation of the lead screw 11 causes the filter screen 5 to move back and forth. This reciprocating movement of the filter screen 5 agitates the feed water inside the treatment chamber 2, thus promoting thorough mixing of the feed water and chemical deoxidizer. After the boiler drum water treatment inside chamber 2 is completed, the motor drives the lead screw 11 to rotate. Through the threaded engagement between the lead screw 11 and the drive sleeve 10, the filter screen 5 is displaced, pushing the compounds and impurities inside the treatment chamber 2 to move, which in turn moves the connecting block 31 and the linkage block 9. When the compounds and impurities inside the treatment chamber 2 pass the baffle 13 and the filter screen 5 is located between the compounds and the baffle 13, the linkage block 9 contacts the push plate 18 and pushes the push plate 18 to move. At this time, the displaced push plate 18 will drive the rack plate 17 to move, and the displaced rack plate 17 will drive the gear to rotate. At this time, the rotating gear will drive the screw 16 to rotate. At this time, the rotating screw 16 and the... The threaded engagement of the sleeve 15 causes the sleeve 15 and the connecting plate 14 to move vertically. This vertical movement of the connecting plate 14 then causes the connecting block and the stop block 13 to move as well. When the stop block 13 disengages from the drain outlet 12, the boiler drum water that has been processed inside the processing chamber 2 enters the drain chamber 3 through the drain outlet 12. The valve can then be opened, and the water inside the drain chamber 3 is transported to the boiler drum through the drain pipe 20. After the water is discharged, the connecting block 31 continues to move. When the connecting block 31 contacts the sealing block 7, the moving connecting block 31 pushes the sealing block 7 to move, causing the sealing block 7 to open the outlet 6. At this point, the compounds and impurities pushed by the filter screen 5 will pass through the outlet. 6. The discharged compounds and impurities will fall into the receiving box 22. The receiving box 22 can then receive the discharged compounds and impurities. When the lead screw 11 rotates, it will drive the bevel gear 2 to rotate. Through the meshing of the bevel gear 2 and the first bevel gear 27, the drive column 23 will rotate. The rotating drive column 23 will drive the first drive plate 24 to deflect, and drive the second drive plate 25 and the third drive plate 26 to deflect, causing the receiving box 22 to reciprocate horizontally. The reciprocating horizontal displacement of the receiving box 22 will cause the compounds and impurities inside the receiving box 22 to shake, thereby leveling the compounds and impurities inside the receiving box 22 and increasing the capacity of the receiving box 22.
