Description

Technical Field

[0001] This utility model belongs to the technical field of dry quenching coke boilers, and specifically relates to a wastewater collection device for dry quenching coke boilers. Background Technology

[0002] Dry quenching refers to a quenching method that uses inert gas to cool red-hot coke. During the dry quenching process, high-temperature red-hot coke is loaded from the top of the dry quenching furnace. Low-temperature inert circulating gas is blown into the red-hot coke layer in the cooling section of the dry quenching furnace by a circulating fan to absorb the sensible heat of the red-hot coke. The high-temperature inert gas coming out of the annular flue of the dry quenching furnace flows through the dry quenching boiler for heat exchange, and the boiler produces steam. The inert gas is circulated and reused in a closed system. Due to the boiler's requirements for boiler water quality, in order to ensure the safe operation of the boiler, it is necessary to discharge the wastewater in the boiler to maintain a certain salt content in the boiler water and to remove insoluble sludge, rust and other impurities.

[0003] Chinese patent CN202420380839.1 discloses a drainage device for a dry quenching coke boiler, comprising a sewage tank, a filter screen, a collection box, and a lead screw. The device is characterized in that: two sliders are connected to the lead screw, the sewage tank is fixedly connected to the sliders, an inlet pipe is fixedly connected to the sewage tank via a second bracket, a first filter screen is slidably connected to the inlet pipe, a collection box is slidably connected to the sewage tank, a second filter screen is fixedly connected to the collection box via a first bracket, an outlet pipe is fixedly connected to the sewage tank, and a flange is fixedly connected to the outlet pipe.

[0004] Currently, because the wastewater from the dry quenching coke boiler has a high temperature after exiting the wastewater blowdown expander, industrial water needs to be injected into the blowdown well to adjust the temperature. However, there are floating or sediment impurities in the wastewater, so it is necessary to filter and collect the impurities in the wastewater.

[0005] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a wastewater collection device for dry quenching coke boilers, comprising a fixed base, a furnace body connected to the top of the fixed base, and a wastewater collection tank connected to the top of the fixed base.

[0009] A water inlet pipe is connected to one side of the furnace body, a support ring is connected to the inside of the wastewater collection tank, a drain pipe is connected to one side of the wastewater collection tank, a cover is snapped onto the top of the wastewater collection tank, and a filter assembly is installed on the wastewater collection tank.

[0030] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0031] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0032] Please see Figures 1-7 As shown, this utility model is a wastewater collection device for dry quenching coke boilers, including a fixed base 1, a furnace body 3 connected to the top of the fixed base 1, and a wastewater collection tank 4 connected to the top of the fixed base 1.

[0033] A water inlet pipe 5 is connected to one side of the furnace body 3, a support ring 6 is connected to the inner side of the wastewater collection tank 4, a drain pipe 7 is connected to one side of the wastewater collection tank 4, a cover 8 is snapped onto the top of the wastewater collection tank 4, and a filter assembly 2 is provided on the wastewater collection tank 4.

[0034] The surface of the filter assembly 2 is connected to the inside of the wastewater collection tank 4 to drive the filter assembly 2 to rotate at a uniform speed to filter the wastewater.

[0035] First, the filter assembly 2 is driven to rotate. Then, the wastewater in the furnace body 3 is introduced into the wastewater collection tank 4 through the inlet pipe 5. Since there is a flow space in the filter assembly 2, the inlet pipe 5 will introduce the wastewater into the flow space and filter it through the filter assembly 2 before collecting it in the wastewater collection tank 4. The rotating filter assembly 2 can prevent impurities from accumulating in one place when filtering wastewater, thus avoiding blockage in a single location. When the filter assembly 2 needs to be cleaned, simply open the cover 8 and pull the filter assembly 2 upwards to remove it for cleaning. Similarly, by reconnecting the filter assembly 2 with the support ring 6, the filter assembly 2 can be driven to rotate again to filter wastewater. The operation is simple.

[0036] The filter assembly 2 rotates slowly and evenly, which helps to filter and intercept impurities on the wastewater evenly on the surface of the filter assembly 2, avoiding blockage of impurities in a single position when filtering wastewater. The support ring 6 slides and engages with the filter assembly 2 to provide support and prevent the filter assembly 2 from falling off. The filter assembly 2 can be removed and cleaned by holding it and moving it upwards. The operation is simple.

[0037] In one embodiment, the filter assembly 2 includes a drive source 21, a driven gear 23, and a filter element 26. The drive source 21 is disposed on the surface of the wastewater collection tank 4. The power output end of the drive source 21 is connected to a drive gear 22. The driven gear 23 meshes with the drive gear 22. A retaining ring 24 is connected to the inner side of the driven gear 23. A water guide hopper 25 is connected to the inner side of the retaining ring 24. The filter element 26 is disposed inside the water guide hopper 25. Four protrusions 27 are connected to the top of the retaining ring 24.

[0038] First, the drive gear 22 is driven to rotate by the drive source 21, which in turn drives the driven gear 23, which meshes with it, to rotate. Since the support ring 6 supports the retaining ring 24, the driven gear 23 drives the retaining ring 24 to rotate on the support ring 6. The retaining ring 24 then drives the filter element 26 to rotate slowly. Afterwards, wastewater from the furnace body 3 is introduced into the wastewater collection tank 4 through the inlet pipe 5. Because there is a flow space between the guide hopper 25 and the filter element 26, the inlet pipe 5 guides the wastewater into this flow space, where it is filtered by the filter element 26 before entering the wastewater collection tank 4 for collection. The rotating driven gear 23... The drive gear 23 drives the filter element 26 to rotate slowly, which can prevent impurities on the filter element 26 from concentrating in one place when filtering wastewater, thus avoiding blockage in a single location. When the filter element 26 needs to be cleaned, after opening the cover 8, pull up two of the protrusions 27, and then move the driven gear 23 and the retaining ring 24 upward to separate them from the support ring 6. Then, tilt the filter element 26 out for cleaning. Similarly, by reconnecting the retaining ring 24 to the support ring 6 and aligning the driven gear 23 with the rack of the drive gear 22, the filter element 26 can be driven to rotate to filter wastewater again. The operation is simple.

[0039] The drive gear 22 drives the driven gear 23, which meshes with it, to rotate, facilitating the uniform and slow rotation of the filter element 26. This ensures that impurities in the wastewater are evenly filtered and intercepted on the surface of the filter element 26, preventing blockage in a single location during wastewater filtration. The support ring 6 slides and engages with the filter element 26, supporting the driven gear 23 and preventing it from disengaging from the drive gear 22. The filter element 26 can be removed for cleaning by grasping the protrusion 27 and moving it upwards. When placing the filter element 26 back into the wastewater collection tank 4, the driven gear 23 and the rack of the drive gear 22 should be aligned without affecting their meshing. The operation is simple.

[0040] In one embodiment, the wastewater collection tank 4 has a through groove on its surface, the drive gear 22 passes through the through groove, and the driven gear 23 is located inside the wastewater collection tank 4, so that the drive gear 22 can drive the driven gear 23 to mesh and rotate.

[0041] In one embodiment, the longitudinal section of the retaining ring 24 and the longitudinal section of the support ring 6 are both "L" shaped, which facilitates the engagement of the retaining ring 24 and the support ring 6.

[0042] In one embodiment, the bottom end of the retaining ring 24 slides and fits against the top end of the support ring 6, thereby supporting the retaining ring 24 through the support ring 6 and preventing the retaining ring 24 from falling off.

[0043] In one embodiment, for the water guide hopper 25, a flow space is provided between the water guide hopper 25 and the filter element 26, and the water inlet pipe 5 is located above the flow space, thereby facilitating the flow of wastewater.

[0044] In one embodiment, the card cover 8 has a rectangular groove on its surface, and the surface of the water inlet pipe 5 slides and fits into the rectangular groove, thereby making it easy to remove the card cover 8.

[0045] In summary, using the above-mentioned technical solution of this utility model, the drive source 21 first drives the active gear 22 to rotate, thereby driving the driven gear 23 meshing with it to rotate. Since the support ring 6 supports the retaining ring 24, the driven gear 23 will drive the retaining ring 24 to rotate on the support ring 6. The retaining ring 24 will drive the filter element 26 to rotate slowly. Then, the wastewater in the furnace body 3 is introduced into the wastewater collection tank 4 through the water inlet pipe 5. Since there is a flow space between the water guide hopper 25 and the filter element 26, the water inlet pipe 5 will introduce the wastewater into the flow space and filter it through the filter element 26 before it enters the wastewater collection tank 4. The filter element 26 is slowly rotated by the driven gear 23 during wastewater filtration, preventing impurities from accumulating in one spot and thus avoiding blockage in a single location. To clean the filter element 26, open the cover 8, pull up two protrusions 27, and then move the driven gear 23 and retaining ring 24 upwards to separate them from the support ring 6. Then, tilt the filter element 26 to remove it for cleaning. Similarly, by reconnecting the retaining ring 24 to the support ring 6 and aligning the driven gear 23 with the rack of the driving gear 22, the filter element 26 can be driven to rotate repeatedly to filter wastewater. The operation is simple.

[0046] Through the above technical solution, the driven gear 23 meshing with the active gear 22 drives the filter element 26 to rotate at a uniform and slow speed, which facilitates the even filtration and interception of impurities on the wastewater on the surface of the filter element 26, avoiding the blockage of impurities in a single position of the filter element 26 when filtering wastewater. Furthermore, the support ring 6 slides and engages with the filter element 26 to support the driven gear 23, preventing the driven gear 23 from disengaging from the active gear 22. The filter element 26 can be removed for cleaning by grasping the protrusion 27 and moving it upwards. When putting the filter element 26 back into the wastewater collection tank 4, the driven gear 23 and the rack of the active gear 22 should be aligned, without affecting the meshing between the driven gear 23 and the active gear 22. The operation is simple.
