Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of molten sulfur treatment in coking plants, and particularly relates to a molten sulfur kettle sulfur discharging device. Background Art
[0002] In the process of producing sulfur, the molten sulfur kettle process is generally adopted, in which steam is used to indirectly heat sulfur foam or sulfur paste to produce liquid sulfur from the sulfur foam or sulfur paste, and the liquid sulfur is discharged from the molten sulfur kettle and cooled into solid sulfur. During the operation, in the process of discharging liquid sulfur, a large amount of toxic and harmful gases will be emitted by the high-temperature liquid sulfur, seriously polluting the atmosphere and causing certain harm to environmental governance. The applicant of this patent, when improving the cooling and recovery of liquid sulfur, changed from the original sulfur discharging box to the cooling drum method to cool the liquid sulfur into a solid and then recover the solid sulfur process, but there is still a problem of unsmooth sulfur discharging. Content of the Utility Model
[0003] In order to solve the above problems, the utility model provides a molten sulfur kettle sulfur discharging device.
[0004] The utility model is realized as follows: A molten sulfur kettle sulfur discharging device includes a cooling mechanism. The cooling mechanism includes a cooling drum, a base, and a motor. The base is provided with a motor and two brackets. Bearings are arranged on the upper parts of the brackets. The cooling drum is arranged between the two brackets. The output shaft of the motor is connected with a driving gear, and the driving gear is meshed and connected with a driven gear. The cooling drum makes a rotational movement on the bearings through the driving gear and the driven gear driven by the motor. Water inlets and outlets for cooling water are respectively arranged in the middle of both ends of the cooling drum. The cooling drum is arranged in a sealing cover. A liquid sulfur tank is arranged under the cooling drum. The liquid sulfur tank is connected with a discharging pipe of the molten sulfur kettle. An air suction port is arranged at the top of the cooling mechanism. The air suction port is connected with a tail gas treatment system. A scraping mechanism is arranged on the cooling drum. The scraping mechanism includes a scraper. A solid sulfur receiving tank is arranged on one side of the bottom of the cooling drum close to the scraper. A material outlet is arranged on one side of the bottom of the receiving tank. The material outlet is connected with a sealed receiving port. A pushing mechanism is arranged in the solid sulfur receiving tank. The pushing mechanism includes a pushing motor. The pushing motor is connected with a power shaft. The power shaft is connected with a first transmission rod. The first transmission rod is connected with a second transmission rod through a first joint. The second transmission rod is connected with a push rod through a second joint. The other end of the push rod is provided with a push plate. The push plate makes a reciprocating movement driven by the pushing motor.
[0005] The liquid sulfur from the sulfur melting kettle enters the liquid sulfur tank. The cooling drum rotates driven by an electric motor. The lower part of the cooling drum is immersed in the liquid sulfur. When rotating, the liquid sulfur is lifted up. On the surface of the cooling drum, the liquid sulfur is cooled to a solid state. At the scraper position, the solid sulfur on the cooling drum is scraped off by the scraper and slides down along the solid sulfur receiving trough to the bottom. The pusher plate reciprocates under the pusher motor, pushing the solid sulfur to the material outlet. It can be directly packaged and stored in woven bags through the sealed material receiving port for external sales or internal use. The cooling drum is arranged in a sealed cover, and an air suction port is arranged on the upper part of the sealed cover. The toxic and harmful gases generated during the whole process are treated by the air suction tail gas treatment system, avoiding environmental pollution.
[0006] The scraper mechanism described above includes a scraper, a support column, and an anti-loosening ejector rod. A support plate is arranged on the upper part of the anti-loosening ejector rod. The scraper is fixed on the rotating shaft. The length of the scraper is slightly longer than the width of the cooling drum and less than the length of the rotating shaft. The support columns are arranged on both sides of the cooling drum. Fixed rings are arranged on the upper parts of the support columns. The rotating shaft passes through the fixed rings. Connecting rings are fixedly arranged at both ends of the rotating shaft. One side of the connecting ring is connected to a counterweight block through a spring.
[0007] The support column plays a supporting role. The rotating shaft passes through the fixed ring and can rotate moderately within the fixed ring. Connecting rings are fixedly arranged at both ends of the rotation. The counterweight block arranged on one side of the connecting ring can drive the rotating shaft to rotate, making the scraper fixedly connected to the rotating shaft closely adhere to the cooling drum, which is beneficial for the scraper to better scrape off the solid sulfur on the cooling drum. Because it is pressed by a spring, the rotating shaft can perform fine rotational self-adjustment, which is beneficial for extending the service life of the scraper.
[0008] The electric motor is a frequency conversion motor, and the rotation speed of the output shaft can be adjusted. A visual window is arranged on the sealed cover. The visual window is sealed with a transparent material. The lower edge of the visual window is flush with the upper edge of the liquid sulfur tank.
[0009] Through the visual window, the situation of the liquid in the liquid sulfur tank can be observed. By adjusting the rotation speed of the electric motor, the rotation speed of the cooling drum can be adjusted, and the cooling speed of the liquid sulfur can be adjusted, so as to control the liquid level of the liquid sulfur and avoid the overflow of the liquid sulfur in the liquid sulfur tank.
[0010] Calibration idler rollers are also arranged on the upper and lower sides of the push rod, which is beneficial for maintaining the horizontal movement of the push rod and better pushing the solid sulfur to the material outlet.
[0011] The second transmission rod is arranged in a split structure. The two sections of the second transmission rod are connected by connecting screw threads. The length of the second traditional rod can be finely adjusted through the screw threads, so as to finely adjust the stroke of the push plate.
[0012] The beneficial effects of the present utility model are as follows: 1. The present utility model has a reasonable structural design and a simplified process, saving manpower and material resources: The liquid sulfur from the sulfur melting kettle enters the liquid sulfur tank, is cooled by the cooling drum, and is pushed to the material outlet under the action of the pushing mechanism, and can be directly packed and stored in woven bags through the sealed material receiving port for external sales or internal use. 2. The toxic and harmful gases generated during the whole process are treated by the suction tail gas treatment system, avoiding environmental pollution. 3. The motor described is a variable frequency motor, which can adjust the rotation speed of the output shaft, can control the liquid level of the liquid sulfur, avoid the overflow of the liquid sulfur in the liquid sulfur tank, and reduce potential safety hazards.
