Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of coal dry distillation discharge, specifically to an automatic pressure control device for coal dry distillation discharge system. BACKGROUND

[0002] The yield and composition of coal dry distillation products depend on the quality of raw coal, furnace structure and processing conditions. With different final dry distillation temperatures, the coal dry distillation products are different. The solid product of low-temperature dry distillation is loose black semi-coke, with low coal gas yield and high tar yield. The solid product of high-temperature dry distillation is dense silver-gray coke, with high coal gas yield and low tar yield. The yield of medium-temperature dry distillation products is between that of low-temperature and high-temperature dry distillation. The main components of coal gas generated during the coal dry distillation process are hydrogen and methane, which can be used as fuel or chemical raw material. High-temperature dry distillation is mainly used for producing metallurgical coke. The obtained tar is a mixture of aromatic hydrocarbons and heterocyclic compounds, which is an important source of aromatic hydrocarbons in industry. Low-temperature dry distillation tar contains more alkanes than high-temperature tar, and is one of the important sources of artificial oil.

[0003] For example, the patent document with the announcement number CN 218738424 U discloses an automatic pressure control device related to the technical field of automatic pressure control. It includes a main pipe, a reduction motor fixedly installed on the outer wall of the main pipe, a micro switch fixedly installed on the outer wall of the main pipe, and a cam fixedly sleeved on the outer wall of the output end of the reduction motor. The automatic pressure control device can automatically release pressure inside the steaming and roasting oven through the setting of the pressure relief device. When the internal gas pressure rises, the micro switch receives a signal to start the reduction motor. The reduction motor drives the cam and the crankshaft to rotate. When the cam rotates to a certain angle, it touches the micro switch, causing the reduction motor to stop rotating. At the same time, the rotation of the crankshaft drives the internal transmission to make the sealing plate move upward, opening the gap above the main pipe for pressure release. When the pressure falls to the preset requirement, the elastic force of the extension spring makes the sealing plate move downward for resetting. Finally, the entire device is closed again for sealing.

[0004] However, this structure can only perform one-way pressure control operation for the coal dry distillation discharge system during actual use, and its pressure control ability is poor. It cannot accurately complete the coal dry distillation discharge regulation and control operation. At the same time, the equipment cannot be quickly assembled and used, and cannot be timely disassembled, replaced and maintained, which cannot meet the daily use requirements. Therefore, it is urgent to design an automatic pressure control device for coal dry distillation discharge system to solve the above problems. SUMMARY

[0005] The purpose of this utility model is to provide an automatic pressure control device for a coal pulverization discharge system, in order to solve the problems mentioned in the background art. In actual use, the existing structure can only perform unidirectional pressure control operation of the coal pulverization discharge system, which has poor pressure control capability and cannot accurately complete the coal pulverization discharge control operation. At the same time, the equipment cannot be quickly assembled and used, and cannot be disassembled and maintained in a timely manner, thus failing to meet the daily use needs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic pressure control device for a coal pulverization discharge system, comprising a conveying seat, with connecting ring seats fixedly connected to the upper and lower ends of the conveying seat, an upper conical cover fixedly connected to the top of the conveying seat via the connecting ring seats, and a lower conical cover fixedly connected to the bottom of the connecting ring seats via the connecting ring seats.

[0007] The upper connecting seat and the lower connecting seat are provided. The top end of the upper conical cover is fixedly connected to the upper connecting seat, and the bottom end of the lower conical cover is fixedly connected to the lower connecting seat. A telescopic cover is fixedly connected to the ends of the upper and lower connecting seats that are far apart from each other. A pressure control ball seat is provided at one end of the telescopic cover.

[0008] Preferably, the upper connecting seat and the lower connecting seat are fixedly connected to a connecting thread at one end near the conveying seat, and a sealing ring is provided on the edge of the upper connecting seat and the lower connecting seat near the conveying seat.

[0009] Preferably, the lower connecting seat is provided with a telescopic airbag inside, and one end of the pressure control ball seat is provided with a pressure control valve port.

[0010] Preferably, the upper conical cover and the lower conical cover are internally connected by a lifting inner seat, and the side of the lifting inner seat is fitted with a sealing ring.

[0011] Preferably, the ends of the upper and lower conical covers that are far apart from each other are provided with threaded connectors.

[0012] Preferably, a first conveying pipe is fixedly connected to one side of the conveying seat, and a second conveying pipe is fixedly connected to the other side of the conveying seat.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This automatic pressure control device for the pulverized coal pyrolysis discharge system, through its components including a conveyor seat, connecting ring seat, upper conical cover, lower conical cover, telescopic cover, pressure control ball seat, telescopic air bladder, pressure control valve port, lifting inner seat, sealing rubber ring, first conveying pipe, and second conveying pipe, effectively improves the automatic pressure control effect of the equipment on the pulverized coal pyrolysis discharge system. In actual use, the operator first rapidly conveys the pulverized coal pyrolysis discharge material through the first and second conveying pipes on the side of the conveyor seat. When the pulverized coal pyrolysis raw material enters... After entering the conveyor seat, air can be injected into the pressure control valve port of the pressure control ball seat. Then, in conjunction with the telescopic airbag inside the telescopic cover, the upper and lower conical covers are fitted together with the lifting inner seats and sealing rings. At this time, the sealing rings on the side of the lifting inner seats can be contracted inside the upper and lower conical covers, thereby synchronously and stably controlling the automatic pressure control operation of the coal pyrolysis discharge inside the conveyor seat. This makes the coal pyrolysis discharge operation more stable and demonstrates the practicality of the equipment design.

[0015] This automatic pressure control device for the pulverized coal dry distillation discharge system further improves the overall performance of the equipment through the design of an upper conical hood, a lower conical hood, an upper connecting seat, a lower connecting seat, a telescopic hood, a pressure control ball seat, a connecting threaded port, a sealing ring, and a threaded connector. During daily use, operators can screw the upper and lower telescopic hoods and the pressure control ball seat onto the threaded connectors on the upper and lower conical hoods respectively through their connecting threaded ports. This allows for quick and easy assembly and installation of the telescopic hoods and pressure control ball seats at the upper and lower conical hoods. The sealing ring ensures a stable and tight seal at the connection points, facilitating the rapid connection and installation of the telescopic airbag with the connecting ring seat and the inner lifting seat and sealing ring inside the upper conical hood. This design ensures that the upper and lower telescopic hoods and the pressure control ball seat can be easily replaced and maintained at the central conveyor seat, demonstrating the comprehensiveness of the equipment design.
