Description

Technical Field

[0001] This utility model relates to the field of chimney technology, and in particular to a chimney bottom drainage device. Background Technology

[0002] A chimney is a structure that provides ventilation for hot flue gas or smoke from boilers, stoves, industrial equipment, or fireplaces. It is usually designed to be vertical or near vertical to ensure that the gas flows smoothly by means of the "chimney effect". After the fuel is burned, water vapor is produced. When the high-temperature flue gas comes into contact with the cooler pipe wall, the water vapor will condense into liquid water. In winter or low-temperature environments, the temperature difference between the flue gas and the outside of the pipe increases, which will accelerate the condensation process.

[0003] However, the following drawbacks still exist: after the existing chimney discharges hot exhaust gas, condensation will be generated due to the temperature difference inside the chimney. Traditional chimney designs usually only consider the exhaust outlet and ventilation needs of the flue gas, without a dedicated drainage device. Most of the condensation accumulates at the bottom of the chimney and is removed by natural evaporation. Long-term accumulation may cause the condensation to erode the bottom of the chimney, thereby damaging the chimney. In order to better address the above problems, promote the development of industry technology, and improve core competitiveness, this application proposes a new composition structure that is different from the existing technology. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a bottom drainage device for chimneys.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bottom drainage device for a chimney includes a chimney body with connecting pipes fixed to both ends. A water storage pipe is fixed to the bottom of the chimney body. A detachable filter assembly is installed inside one end of the water storage pipe. A fixed block is movably connected inside the water storage pipe. A piston block is fixedly connected to one side of the fixed block and contacts the inside of the water storage pipe. A pressure plate is fixedly connected to one end of the water storage pipe. A threaded rod is movably connected to the pressure plate and rotatably connected to the fixed block. A water outlet is opened at the bottom of the water storage pipe, and a water outlet pipe is fixedly connected inside the water outlet. A triangular shell is fixedly connected to the bottom of the water storage pipe. A collection box is movably connected inside the triangular shell through a guide assembly, and the water outlet pipe is connected to the collection box.

[0007] As a further embodiment of this utility model, a nut is movably connected to one end of the threaded rod extending out of the fixing block, and the nut is in contact with the pressure plate.

[0008] As a further embodiment of this utility model, two guide rods are fixedly connected to one side of the fixing block, and the guide rods are slidably connected along the pressure plate.

[0009] As a further embodiment of this utility model, the filter assembly includes a protective shell, which is fitted onto one end of the water storage pipe. A sealing plug is fixedly connected to the inner wall of one side of the protective shell, and the sealing plug blocks one end of the water storage pipe. Two connecting posts are fixedly connected to one side of the protective shell, and the two connecting posts pass through the sealing plug and are fixedly connected to a stainless steel strainer.

[0010] As a further embodiment of this invention, the stainless steel strainer is in contact with the inner wall of the water storage pipe.

[0011] As a further embodiment of this invention, a flange is fixedly connected to one end of the connecting pipe.

[0012] As a further embodiment of this utility model, the guide component includes a dovetail groove, which is formed on the bottom outer wall of the collection box.

[0013] As a further embodiment of this invention, a handle is fixedly connected to one side of the outer wall of the collection box.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This utility model, through the combined use of a collection box and a piston block, facilitates the collection and centralized treatment of condensate inside the chimney body, preventing condensate from accumulating at the bottom of the chimney body and relying on natural evaporation, which would cause long-term corrosion to the bottom of the chimney body, thus improving the effectiveness of the device.

[0016] 2. This utility model uses a combination of a sealing plug and a stainless steel strainer to filter impurities in condensate water, and also makes it easier for staff to remove the filtered impurities, thus improving the convenience of the device.

[0017] 3. This utility model can further restrict and fix the position of the threaded rod by using a nut, thereby making the position of the piston block more stable. Attached Figure Description

Therefore, all other embodiments of this application described herein, and all embodiments obtained by those skilled in the art without creative effort based on the embodiments in this application, should fall within the scope of protection of this application.

[0024] Reference Figures 1-4 A bottom drainage device for a chimney includes a chimney body 8, with connecting pipes 1 fixedly connected to both ends of the chimney body 8. A water storage pipe 6 is fixedly connected to the bottom end of the chimney body 8. A detachable filter assembly is provided inside one end of the water storage pipe 6. The filter assembly includes a protective shell 9, which is sleeved on one end of the water storage pipe 6. A sealing plug 12 is fixed to the inner wall of one side of the protective shell 9 by bolts, and the sealing plug 12 blocks one end of the water storage pipe 6. Two connecting posts 13 are fixed to one side of the protective shell 9 by bolts. The two connecting posts 13 pass through... A stainless steel strainer 14 is fixed to the sealing plug 12 and bolted together. The stainless steel strainer 14 is in contact with the inner wall of the water storage pipe 6. When it is necessary to clean the impurities filtered out by the stainless steel strainer 14, the staff pulls the protective shell 9, which moves the sealing plug 12 out of the water storage pipe 6. At the same time, the connecting column 13 moves the stainless steel strainer 14 out of the water storage pipe 6, thereby pushing out the impurities filtered out of the water storage pipe 6 by the stainless steel strainer 14. This also makes it easier for the staff to use cleaning tools to clean the leak holes on the stainless steel strainer 14.

[0025] A fixed block 16 is slidably connected inside the water storage pipe 6. A piston block 15 is adhered to one side of the fixed block 16 and is in contact with the inside of the water storage pipe 6. When the high-temperature flue gas comes into contact with the cooler wall of the chimney body 8, the water vapor condenses into liquid water. The condensate enters the water storage pipe 6 through the chimney body 8. A stainless steel strainer 14 filters impurities in the condensate. The filtered condensate moves along the inclination of the water storage pipe 6 into the space between the stainless steel strainer 14 and the piston block 15. A pressure plate 5 is fixed to one end of the water storage pipe 6 by bolts. A threaded rod 4 is threaded onto the pressure plate 5 and is rotatably connected to the fixed block 16. The bottom of the water storage pipe 6... The system has an outlet, through which an outlet pipe 17 is fixedly connected. A triangular shell 2 is fixedly connected to the bottom of a water storage pipe 6. A collection box 11 is slidably connected inside the triangular shell 2 via a guide assembly. The outlet pipe 17 is connected to the collection box 11. When the operator rotates the threaded rod 4, the fixing block 16 moves the piston block 15 outward along the water storage pipe 6 until the piston block 15 separates from the outlet pipe 17. At this time, the liquid in the space between the stainless steel strainer 14 and the piston block 15 in the water storage pipe 6 enters the collection box 11 through the outlet pipe 17. The operator pulls the collection box 11 to move it out of the triangular shell 2, thus facilitating the centralized processing of the collected liquid.

[0026] The guiding assembly includes a dovetail groove 19, which is formed on the bottom outer wall of the collection box 11. The bottom inner wall of the triangular shell 2 is fixed with a guide rail by bolts, and the guide rail is slidably connected to the dovetail groove 19. Through the cooperation of the guide rail and the dovetail groove 19, the collection box 11 can be guided and is easy to position and install. The threaded rod 4 extends out of the fixing block 16 and is threadedly connected to a nut 3. The nut 3 is in contact with the pressure plate 5. The nut 3 can further restrict and fix the position of the threaded rod 4. Two guide rods 10 are fixed on one side of the fixing block 16 by bolts, and the guide rods 10 are slidably connected along the pressure plate 5. The guide rods 10 can guide the fixing block 16 so that it can move stably along the water storage pipe 6. One end of the connecting pipe 1 is fixed with a flange 7 by bolts, which is convenient to connect to the pipe of the external smoke exhaust equipment. One side outer wall of the collection box 11 is fixed with a handle 18 by bolts, which is convenient to pull and move the collection box 11. The smoke exhaust port at the top of the chimney body 8 is connected to a rain cover, and the two ends of the rain cover are open.

[0027] Working principle: In use, the chimney body 8 is first connected and fixed to the pipes of the external boiler or other flue gas equipment through the flanges 7 on the two connecting pipes 1, so that the external flue gas enters the chimney body 8 through the connecting pipes 1 and is discharged through the flue gas outlet at the top of the chimney body 8. When the high-temperature flue gas comes into contact with the pipe wall of the chimney body 8 with a lower temperature, the water vapor will condense into liquid water. The condensate enters the water storage pipe 6 through the chimney body 8. The stainless steel strainer 14 filters the impurities in the condensate. The filtered condensate moves along the inclination of the water storage pipe 6 to the space between the stainless steel strainer 14 and the piston block 15. Then, the operator rotates the threaded rod 4, so that the fixing block 16 drives the piston block 15 to move outward along the water storage pipe 6 until the piston block 15 separates from the water outlet pipe 17. At this time, the liquid in the space between the stainless steel strainer 14 and the piston block 15 in the water storage pipe 6 enters the collection box 11 through the water outlet pipe 17. The operator pulls the handle 18 to move the collection box 11 out of the triangular shell 2, so that the operator can collect the liquid for centralized treatment.
