Description

Continuous airtight buffering storehouse formula screw dehydrator for decoking Technical Field The utility model relates to the technical field of petrochemical equipment, in particular to a continuous closed buffer bin type spiral dehydrator for decoking. Background In the decoking process of the coke tower of the current delayed coking device, such as the traditional decoking mode like CCS, the existing techniques of shed type sealing, tank type sealing and the like all adopt the technology of directly discharging coke and coke cutting water from the bottom outlet of the coke tower, entering a coke tank or a dewatering bin, and dewatering by utilizing the gap natural gravity water filtration generated by coke material accumulation, wherein the natural dewatering period is as long as 3-5 hours. And the natural gravity dewatering is adopted, so that the natural spreading area is large, and the stacking space is also large, and therefore, the gravity water filtering dewatering of a coke pond and a dewatering bin is adopted, the occupied area is large, the volume is large, the utilization rate is low, and the investment is large. The gravity drainage dehydration period of the coke pond and the dehydration bin is too long, only an intermittent working flow can be adopted, the waiting time is too long, the operation of subsequent equipment cannot be synchronously carried out with the dehydration process, and the decoking and transferring efficiency is low. Therefore, a continuous closed coke-removing buffer bin type spiral dehydrator is needed to solve the technical problems. Disclosure of utility model The utility model provides a continuous closed buffer bin type spiral dehydrator for decoking aiming at the technical problems in the prior art. The utility model solves the technical problems by adopting the technical scheme that the continuous sealed coke-removing buffer bin type spiral dehydrator comprises a sealing bin and an overflow bin, wherein the sealing bin is obliquely arranged, the overflow bin is arranged at the upper end of the sealing bin, the sealing bin comprises a separation bin and a drainage bin, the overflow bin is communicated with the upper end of the separation bin, a discharging hopper is arranged at the upper end of the separation bin, a spiral auger is arranged in the separation bin, a filter screen is arranged at the bottom of the separation bin, the drainage bin is arranged below the separation bin, a motor and a transmission box are arranged at the upper end of the sealing bin, an output shaft of the motor is connected with the upper end of the spiral auger through the transmission box, a slag discharging port and an auger support are arranged at the lower end of the separation bin, a sealing plate is arranged at the slag discharging port, and a water discharging port is arranged at the bottom of the drainage bin.
