In order to achieve the above purpose, the technical scheme of the utility model is that: the utility model provides a belt corridor blowdown preliminary treatment pond, includes preliminary treatment pond, be provided with the partition wall unanimous with preliminary treatment pond shape in the preliminary treatment pond, partition wall and preliminary treatment pond set up with one heart, the height that highly is less than preliminary treatment pond wall of partition wall, partition wall fall into first sedimentation tank, second sedimentation tank with preliminary treatment pond, first sedimentation tank side wall bottom is provided with sewage entry, is provided with the precipitation packing layer in the first sedimentation tank, be provided with infundibulate guide plate, riser in the second sedimentation tank, the riser sets up at second sedimentation tank center, and the height that highly is less than the partition wall of riser, and the riser center is provided with the water pump, infundibulate guide plate major end is downward, the tip upwards sets up, and the tip suit is in the riser outside, with riser outer wall interval 10 ~ 15cm, major end and partition wall inner wall interval 10 ~ 15 cm.

The precipitation packing layer is positioned at the upper part of the sewage inlet and is a honeycomb inclined tube packing.

The partition wall is 30-50 cm lower than the wall of the pretreatment water tank, and the vertical pipe is 30-50 cm lower than the partition wall.

The funnel-shaped guide plate is detachably and fixedly connected with the partition wall.

The bottom surface of the first sedimentation tank is 100-150 cm higher than that of the second sedimentation tank.

The pretreatment water pool and the partition wall are round or square.

The small end face of the funnel-shaped guide plate is higher than the top end of the vertical pipe.

The utility model discloses simple structure, convenient to use effectively carries out the preliminary treatment to the sewage of dry coke quenching belt vestibule, and high efficiency reduces the burnt powder content in the sewage, and structural design is reasonable simultaneously, has still played effectual guard action to the sewage pump when removing the burnt powder in the sewage, has prolonged the life of sewage pump, and economic benefits is showing.

Detailed Description

As shown in figures 1 and 2, a belt corridor sewage disposal pretreatment water tank comprises a circular pretreatment water tank 1, wherein a circular partition wall 2 is arranged in the pretreatment water tank 1, the partition wall 2 and the pretreatment water tank 1 are arranged concentrically, the pretreatment water tank is divided into a first sedimentation tank 3 and a second sedimentation tank 4 by the partition wall 2, the height of the partition wall is 30-50 cm lower than the wall of the pretreatment water tank, the partition wall forms overflow of the first sedimentation tank to the second sedimentation tank, a sewage inlet 31 is arranged at the bottom of the side wall of the first sedimentation tank 3, a honeycomb inclined tube packing layer 32 is arranged in the first sedimentation tank 3 and is positioned above the sewage inlet, excessive coke powder in sewage can be rapidly precipitated and removed, a funnel-shaped guide plate 5 and a vertical pipe 6 are arranged in the second sedimentation tank 4, the vertical pipe 6 is arranged in the center of the second sedimentation tank, the height of the vertical pipe 6 is 30-50 cm lower than the height of the partition wall 2, the vertical pipe forms overflow of, the 6 centers of riser are provided with water pump 7, 5 detachable installations of infundibulate guide plate are on the partition wall, be convenient for use in the clearance to the second sedimentation tank, infundibulate guide plate major part end is downward, the microcephaly end upwards sets up, microcephaly end suit is in the riser outside, with riser outer wall interval 10 ~ 15cm, macrocephaly end and partition wall inner wall interval 10 ~ 15cm, the guide plate slowly sends into the water of overflow second sedimentation tank, the guide plate can play the influence that prevents new overflow entering second sedimentation tank's water to water after having deposiing, can be with the higher riser that guide plate microcephaly end set up simultaneously, when overflow water is too big, guarantee that new overflow gets into the water of second sedimentation tank and not directly gush into the riser. This application is to preliminary treatment pond of dry coke quenching belt vestibule sewage, the purpose is to carry out preliminary treatment to sewage, prevent the influence of too much burnt powder to follow-up workshop section in the sewage, furthest is served in follow-up workshop section, the bottom surface of the first sedimentation tank of this application is higher than 100 ~ 150cm in second sedimentation tank bottom surface, the sewage overflow speed of first sedimentation tank is accelerated to the more shallow of first sedimentation tank degree of depth like this, the clarification effect is guaranteed to the second sedimentation tank is darker, thereby guarantee that the burnt powder content of second sedimentation tank overflow in to the riser is lower, guarantee water pumping equipment's long-term steady operation.

During the use, with belt vestibule sewage pipe arrange sewage pipe with this application device's sewage entry intercommunication can, the sewage that flows out from belt vestibule gets into first sedimentation tank, through the filtration of packing layer, rapid filtration most coke breeze and particulate matter, then the second sedimentation tank is gone into to the overflow, it sends into the second sedimentation tank with the sewage of overflow slowly adherence to be provided with the guide plate on the second sedimentation tank and deposits, the water of second sedimentation tank goes into the stand pipe at the overflow, the coke breeze content in the sewage has been very low this moment can effectively guarantee the life of water pump and the safe handling of follow-up workshop section equipment, the coke breeze of this application device recovery simultaneously can be retrieved and is being utilized.

Example 2
