Description

Technical Field

[0001] The utility model relates to the technical field of flash tanks, in particular to a wastewater flash tank. Background Art

[0002] Flash evaporation is a phenomenon in which high-temperature and high-pressure saturated water enters a relatively low-pressure container, and due to the sudden drop in pressure, these saturated waters turn into saturated water vapor and low-temperature and low-pressure saturated water;

[0003] For example, patent number CN202322523004.5 discloses a wastewater flash tank, the structure of which includes a flash tank body. A filtering mechanism for filtering high-temperature wastewater is provided between the top of the flash tank body and the bottom of the rectifying column. One side of the flash tank body is connected to a vacuum ejector pump. A manhole for internal maintenance use is also provided on the side of the flash tank body. The vacuum ejector pump is also connected to the rectifying column. One end of the vacuum ejector pump is connected to an input pipe for inputting fresh steam. A plurality of support columns for supporting the flash tank body are evenly provided at the bottom of the flash tank body. A drain pipe for discharging low-temperature wastewater is provided at the bottom of the flash tank. By setting a filtering mechanism between the flash tank body and the bottom of the rectifying column, the high-temperature wastewater is filtered before input. Through the first filter screen and the second filter screen, the high-temperature wastewater is filtered twice to separate the wastewater from solid impurities, avoiding the blockage of the vacuum ejector pump caused by solid impurities when the high-temperature wastewater flows through the vacuum ejector pump, resulting in the influence on the injection speed and the inability to achieve flash evaporation. It solves the problem that the high-temperature wastewater discharged from the bottom of the traditional rectifying column contains solid impurities, which are prone to block the internal structure of the vacuum ejector pump when passing through the vacuum ejector pump at high speed, affecting the flash evaporation effect of the wastewater.

[0004] Therefore, aiming at the problem that there is no flow-limiting structure in the liquid inlet pipeline of the flash tank to prevent excessive wastewater from entering the flash tank and unable to perform flash evaporation work properly, a structure with adjustable flow limitation can be designed to improve the subsequent practical efficiency. Summary of the Utility Model

[0008] As a preference, a pull rod is connected through the inside of the movable groove, a spring located inside the movable groove is sleeved on the outside of the pull rod, a plug block inserted inside the slot is fixedly arranged on the lower end surface of the pull rod. Through the installation of the annular plate, its disassembly and assembly structure is relatively simple.

[0009] As a preference, arc-shaped grooves are opened on both sides inside the installation block, and both gears are located inside the two arc-shaped grooves, which are used for the operation of the gears.

[0010] As a preference, an auxiliary block is fixedly arranged at one end of the pull rod away from the plug block, and a rubber anti-slip pad is arranged on the surface of the auxiliary block, which plays an auxiliary anti-slip role.

[0011] As a preference, a rotating shaft is connected through the inside of the gear, coupling devices are arranged at both the front and rear ends inside the installation block, and both the front and rear ends of the rotating shaft are inserted into the two coupling devices, so that the gears can all perform displacement operations.

That is, the current limiting net is located above the inlets opened inside the connecting block, and at the same time, a certain limiting effect on the waste water flow rate is achieved, preventing excessive water flow from causing subsequent work to be unable to proceed;

[0015] 2. When installing the annular plate, first pull the pull rod, so that the spring sleeved outside it is compressed. Then, snap it into the installation groove inside the installation block for fixation.

[0022] The present utility model will be further described below with reference to the drawings and embodiments.

[0023] Please refer to ( Figures 1-5 ), the present utility model provides an embodiment: A wastewater flash evaporation tank, including a flash evaporation tank 1, a connecting pipe 2 is fixedly arranged on the upper end surface of the flash evaporation tank 1, a liquid inlet pipe 3 is arranged above the connecting pipe 2, a connecting block 8 is arranged inside the liquid inlet pipe 3, a plurality of uniformly arranged inlets 9 are opened through the diameter inside the connecting block 8, a funnel 10 is fixedly arranged on the lower end surface of the connecting block 8, a limit sliding groove 7 is opened on one side of the liquid inlet pipe 3, tooth grooves 12 are arranged on both the left and right sides of the inner wall of the limit sliding groove 7, an installation block 11 is slidably connected inside the limit sliding groove 7, gears 13 meshed with the tooth grooves 12 are arranged on both the left and right sides of the installation block 11, an installation groove 14 is arranged inside the installation block 11, an annular plate 5 is clamped inside the installation groove 14, and a current-limiting net 6 is arranged inside the annular plate 5.

[0024] Please refer to ( Figures 4-5 ). In this embodiment, slots 19 are provided on the left and right sides of the upper and lower ends inside the annular plate 5. Activity slots 17 are provided on the left and right sides of the upper and lower ends inside the mounting block 11. A pull rod 15 is connected through the inside of the activity slot 17. A spring 16 located inside the activity slot 17 is sleeved on the outside of the pull rod 15. A plug 18 inserted into the slot 19 is fixedly arranged on the lower end surface of the pull rod 15. The flow rate can be controlled inside the flash tank 1 through the connecting block 8 and the internal inlet 9. Then, the flow rate also needs to be limited. The annular plate 5 with the flow limiting net 6 is clamped into the mounting block 11 for fixation. By sliding the mounting block 11 inside the limit sliding groove 7, the gears 13 on both sides of the mounting block 11 are engaged with the tooth grooves 12, and the flow limiting net 6 can be adjusted up and down.

[0025] Please refer to ( Figures 1-4 ). In this embodiment, arc-shaped grooves are provided on both sides inside the mounting block 11. The two gears 13 are both located in the two arc-shaped grooves. An auxiliary block is fixedly arranged at one end of the pull rod 15 away from the plug 18.

Couplings are arranged at the front and rear ends inside the mounting block 11. The front and rear ends of the rotating shaft are inserted into the two couplings. Annular sleeves are arranged on the left and right sides below the flash tank 1. Support blocks 4 are fixedly arranged on the lower end surfaces of the two annular sleeves, so that the flow limiting net 6 is located above the inlet 9 opened inside the connecting block 8. Then, a certain limiting effect is exerted on the waste water flow rate to prevent the subsequent work from being unable to proceed due to excessive water flow. When installing the annular plate 5, first pull the pull rod 15, so that the spring 16 sleeved on its outside is compressed, and then it is clamped into the installation groove 14 inside the mounting block 11 for fixation.

[0026] When working, the flow rate inside the flash tank 1 can be controlled through the connecting block 8 and the internal inlet 9. At the same time, the flow rate needs to be restricted.

Then, snap it into the installation groove 14 inside the installation block 11 for fixation. Finally, release the pulled pull rod 15 so that the spring 16 pops it out, and the insertion block 18 is inserted into the slot 19 inside the annular plate 5 for fixation to complete the installation of the annular plate 5.

[0027] Through the above steps, the flow rate inside the flash tank can be controlled through the connecting block and the internal inlet. At the same time, the flow rate needs to be restricted. The annular plate with a flow-limiting net is snapped into the installation block for fixation. Then, by sliding the installation block inside the limit sliding groove, the gears on both sides of the installation block are engaged with the tooth grooves to adjust the flow-limiting net up and down. The flow-limiting net is located above the inlet opened inside the connecting block, and at the same time, a certain limiting effect on the waste water flow rate is achieved to prevent excessive water flow from causing subsequent work to be unable to proceed, so as to solve the problem that there is no flow-limiting structure in the liquid inlet pipeline of the flash tank and avoid the problem that too much waste water enters the flash tank and the flash work cannot be carried out normally.
