Description

Technical Field

[0001] The present application relates to the technical field of Fischer-Tropsch wax processing, and in particular to a granulator for Fischer-Tropsch wax. Background Art

[0002] With the rapid development of my country's economy, the use of Fischer-Tropsch wax has become more and more widespread. Fischer-Tropsch wax is a methylene polymer produced by Fischer-Tropsch synthesis reaction with the action of synthesis gas in the presence of a catalyst. It has many excellent properties. As various industries continue to increase their requirements for product quality and performance, higher requirements have been placed on the quality and particle morphology of Fischer-Tropsch wax. Granulation is an important part of the Fischer-Tropsch wax production process, and the performance of its granulator directly affects the quality and production efficiency of Fischer-Tropsch wax products.

[0003] However, during the use of the existing Fischer-Tropsch wax granulator, the solution after the Fischer-Tropsch wax is melted mostly flows in large quantities from the feed port of the extrusion barrel, which causes the solution to be extremely unevenly distributed in the process of entering the extrusion barrel. There may be a situation where there is too much material in some areas and too little material in other areas. As a result, during extrusion granulation, the extrusion pressure on the particles in different parts varies greatly, resulting in uneven particle size and shape, affecting the quality of granulation.

[0004] At the same time, it is difficult for the existing Fischer-Tropsch wax granulator to automatically adjust the material feeding speed during the material extrusion process, and most of them require a separate driving mechanism for adjustment, thereby increasing the use cost of the equipment.

The upper part of the front end of the negative pressure feeding box 406 is connected with a central The intermediate connecting pipe 414 and the middle part of the intermediate connecting pipe 414 are fixedly connected with a one-way valve 415, the upper end of the intermediate connecting pipe 414 passes through the sealing narrow rotating ring 413 and is connected to the annular feeding cover 410, the front end of the extrusion cylinder 102 and the rear end of the assembly cylinder 103 are internally rotatably connected with a sealing wide rotating ring 417, the middle part of the front end of the negative pressure feeding box 406 is connected with a liquid feeding pipe 418, the liquid feeding pipe 418 passes through the sealing wide rotating ring 417 and is connected to the extrusion cylinder 102, the front end of the reciprocating screw 402 is rotatably connected to the annular plate 401, the middle part of the feeding pipe 411 is provided with an electromagnetic control valve 412, and the end of the sealing narrow rotating ring 413 away from the negative pressure feeding box 406 is fixedly connected with a plurality of spoiler frames 416, and the spoiler frames 416 are located on the annular Inside the shaped feeding cover 410, the outer wall of the front end of the negative pressure feeding box 406 is fixedly connected with a rectangular connecting frame 420, and the end of the rectangular connecting frame 420 away from the negative pressure feeding box 406 is fixedly connected to the sealing narrow rotating ring 413, and both sides of the outer wall of the front end of the negative pressure feeding box 406 are fixedly connected with L-shaped connecting frames 419, and the end of the L-shaped connecting frame 419 away from the negative pressure feeding box 406 is fixedly connected to the outer wall of the middle part of the sealing wide rotating ring 417. Specifically, in the process of processing Fischer-Tropsch wax, by starting the first servo motor 104 to drive the auger blade 105 to rotate, the positioning ring 301 and the assembly frame 303 will also rotate synchronously. At this time, the assembly frame 303 will drive the negative pressure feeding box 406, the reciprocating screw 402 and the reciprocating slider 407 to rotate.At this time, the driven gear 403 will mesh with the gear ring 405 to make the reciprocating screw 402 rotate, and at the same time, the reciprocating sliders 407 are arranged in a staggered manner on the shaft of the reciprocating screw 402. As a result, during the rotation of multiple reciprocating screws 402, three staggered reciprocating sliders 407 and connecting sliders 408 will slide outward from the inside of the negative pressure feeding box 406, and the other three reciprocating sliders 407 and connecting sliders 408 will move inward from the outer end of the negative pressure feeding box 406. At this time, the three connecting sliders 408 will form a negative pressure in the sealing baffle 409 inside the negative pressure feeding box 406 during the process of moving outward, so that the intermediate connecting pipe 414 absorbs the Fischer-Tropsch wax solution from the inside of the annular feeding cover 410. At this time, the one-way valve 41 5 is in the open state, at this time, when the other three connecting slides 408 move into the negative pressure feeding box 406, the Fischer-Tropsch wax solution absorbed in the negative pressure process in the negative pressure feeding box 406 will flow into the extrusion barrel 102 through the liquid feeding pipe 418, and then, during the continuous rotation of the reciprocating screw 402, the Fischer-Tropsch wax solution in the three negative pressure feeding boxes 406 can enter the extrusion barrel 102, and the other three negative pressure feeding boxes 406 absorb the Fischer-Tropsch wax solution from the inside of the annular feeding cover 410, thereby realizing the function of intermittently and evenly discharging the Fischer-Tropsch wax solution into the extrusion barrel 102, which can avoid the uneven distribution of materials caused by a large amount of solution pouring into the extrusion barrel 102 at one time, wherein, while the auger blade 105 is extruding and feeding, When the assembly frame 303 is rotated, firstly, the Fischer-Tropsch wax solution inside the raw material stirring and heating mechanism 2 can flow into the interior of the extrusion granulation mechanism 1 intermittently and evenly, thereby avoiding the problem of uneven material distribution caused by a large amount of solution pouring into the extrusion barrel 102 at one time; secondly, the three negative pressure feeding boxes 406 are made to work alternately, which can ensure the continuous supply of the Fischer-Tropsch wax solution, and also provide a heating buffer time for the raw material stirring and heating mechanism 2, so that it can stably replenish the solution, thereby improving the operation efficiency of the entire granulation system; thirdly, because the entry of the solution is regular, the flow state of the Fischer-Tropsch wax in the extrusion barrel 102 is more stable under the push of the auger blade 105, which is conducive to maintaining a stable extrusion speed during extrusion granulation, thereby improving the granule Fourthly, through intermittent uniform feeding, the material can be more evenly subjected to the extrusion force and other effects in the extrusion barrel 102, thereby improving the quality consistency of the product. Fifthly, in the process of intermittent uniform feeding of the negative pressure feeding box 406, the spoiler 416 can also stir the heated solution inside the annular feeding cover 410 in real time, so that the solution in the annular feeding cover 410 is in a good flow state, and there will be no feeding interruption or unevenness caused by local solution coagulation or poor fluidity, thereby ensuring the stability of the entire intermittent uniform feeding process. Sixthly, the stirring of the spoiler 416 can make these components fully mixed, ensuring that the solution components absorbed by the negative pressure feeding box 406 are consistent each time, thereby ensuring the quality stability of the granulated product.Seventh, the speed of intermittent uniform feeding corresponds to the rotation speed of the auger blade 105, thereby ensuring the correspondence between the extrusion speed and the feeding speed and improving the stability of the device.

[0054] Specifically, the working principle of this Fischer-Tropsch wax granulator is as follows: Specifically, in the process of processing Fischer-Tropsch wax, by starting the first servo motor 104 to drive the auger blade 105 to rotate, the positioning ring 301 and the assembly frame 303 will also rotate synchronously. At this time, the assembly frame 303 will drive the negative pressure feeding box 406, the reciprocating screw 402 and the reciprocating slider 407 to rotate. At this time, the driven gear 403 will engage with the gear ring 405 to make the reciprocating screw 402 rotate. At the same time, the reciprocating slider 407 is located on the rod body of the reciprocating screw 402 in an staggered manner. In the process of rotation of multiple reciprocating screws 402, three staggered reciprocating sliders 407 and connecting sliders 408 will slide from the inside of the negative pressure feeding box 406 to the outside, and the other three reciprocating sliders 407 and connecting sliders 408 will move from the outer end of the negative pressure feeding box 406 to the inside. At this time, the three connecting sliders 408 are moving toward During the external movement, the sealing baffle 409 will form a negative pressure inside the negative pressure feeding box 406, and then the intermediate connecting pipe 414 will absorb the Fischer-Tropsch wax solution from the inside of the annular feeding cover 410. At this time, the one-way valve 415 is in an open state. At this time, when the other three connecting slides 408 move toward the inside of the negative pressure feeding box 406, the Fischer-Tropsch wax solution absorbed by the inside of the negative pressure feeding box 406 during the negative pressure process will flow to the inside of the extrusion barrel 102 through the liquid delivery pipe 418, and then in the process of continuous rotation of the reciprocating screw 402, the Fischer-Tropsch wax solution inside the three negative pressure feeding boxes 406 can enter the inside of the extrusion barrel 102, and the other three negative pressure feeding boxes 406 absorb the Fischer-Tropsch wax solution from the inside of the annular feeding cover 410, thereby realizing the function of intermittently and evenly discharging the Fischer-Tropsch wax solution into the inside of the extrusion barrel 102, which can avoid the phenomenon of uneven material distribution caused by a large amount of solution pouring into the extrusion barrel 102 at one time.
