Problems solved by technology

[0004] However, due to the need to scrape away the coke trapped in the filter screen, the filter screen in the plate chain conveyor usually has to bear scraper friction. With the continuous operation of the plate chain conveyor, the metal wire of the filter screen is easily broken due to excessive wear , in the slightest, the filtering effect will be lost, and the large particles of coke will pass through to affect the filtering effect. When the chain of the conveyor is broken or the card falls off, it is necessary to timely and accurately judge whether the plate chain conveyor is broken. However, the current detection methods have a certain lag, the detection response is not sensitive, and the reliability is low. Chain processing measures cannot be carried out in time, and there are great hidden dangers in the safe operation of equipment

Embodiment 2

[0070] Different from the setting of the gasket 1603 corresponding to each group of bolts 1601 and nuts 1602 in the first embodiment, in the plate chain conveyor for delayed coking water and coke separation in this embodiment, the height adjustment structure 16 is adjusted as follows: Figure 5 and Figure 7 As shown, the bolts 1601 and the nuts 1602 are respectively provided in multiple groups along the two ends of the frame 1502, and the bolts 1601 and the nuts 1602 at each end of the frame 1502 are arranged in a row, that is, the bolts 1601 and the nuts 1602 are arranged in a row at each end of the frame 1502, respectively. The gaskets 1603 are arranged in rows, the gaskets 1603 are adapted to the length of the row of bolts 1601 and nuts 1602, and the gaskets 1603 are arranged in strips, that is, the entire row of bolts 1601 and nuts 1602 share a layer of gaskets. After removing the bolts 1601 When taking out the gaskets 1603 , the number of gaskets 1603 corresponding to on...

Embodiment 3

[0073] Since the plate chain conveyors provided in the first and second embodiments are conveyed in a long straight section, there are only the head wheel and the tail wheel, compared with the existing coking plate chain composed of three sections: horizontal section, inclined ascending section and tail tension section The conveyor does not need to set the guide wheel located under the water to avoid the material turning during transportation, and the material will not roll over at the guide wheel. However, when the upper chamber 610 and the lower chamber 611 are specifically set, because the spacer 12 is usually set between the head wheel 603 and the tail wheel 608, the tail wheel 608 is at a lower part of the inclined conveyance, and the scraper follows the scraper. When the chain enters the upper chamber 610 from the lower chamber 611 around the end of the tail wheel 608, the coke-water mixture in the upper chamber 610 may leak into the lower chamber 611 at the end of the ta...

Abstract

A plate chain conveyor for delayed coking water-coke separation and a water-coke separation system.The plate chain conveyor comprises a machine body and a scraper chain which is obliquely arranged in the machine body and driven by a head wheel and a tail wheel, a scraper is arranged on the scraper chain, and an interlayer located between an upper return stroke section and a lower return stroke section of the chain is arranged in the machine body along the chain; the machine body is provided with an interlayer, a sieve plate for separating a coke-water mixture is arranged on the interlayer, the machine body is divided into an upper chamber for feeding the coke-water mixture and a lower chamber for collecting water by the interlayer and the sieve plate, a wear-resistant steel plate is arranged on the interlayer, and the sieve plate is lower than the wear-resistant steel plate and is arranged on the interlayer through a height adjusting structure. When the plate chain conveyor is used, the installation height of the frame can be continuously adjusted along with abrasion of the abrasion-resistant steel plate, so that the frame and the screen are always in an installation state lower than the height of the abrasion-resistant steel plate, a filter screen is effectively prevented from being abraded by a scraper, and the safety and stability of the plate chain conveyor during operation are improved.

Description

technical field [0001] The invention relates to the technical field of water-containing solid conveying in the refining and chemical industry, in particular to a plate chain conveyor for water and coke separation in delayed coking and a water and coke separation system. Background technique [0002] The delayed coking refining process has unique advantages in processing heavy and inferior raw materials, and it has become the most commonly used residue heavy oil processing technology. For coke treatment, the coke and coke cutting water in the process of hydraulic decoking are discharged together from the coke tower into the open-air coke storage tank, the solid coke and the coke cutting water are separated in the coke storage tank, the coke cutting water is discharged, and the coke stays in the coke tank. , and then loaded and transported out by an overhead grab crane. The processes of decoking, dehydration, coke removal, transportation, storage and loading are all open opera...
