Description

Technical Field

[0001] The present invention relates to the technical field of tar residue separation, and particularly to a crushing treatment device for tar residue recovery. Background Art

[0002] In the process of coke oven production, under the condition that the produced high-temperature coke oven gas is cooled in the collecting pipe or the primary cooler, high-boiling organic compounds are condensed to form coal tar. At the same time, coal powder, coke powder, free carbon generated by pyrolysis at the top of the carbonization chamber, and porous substances brought in when cleaning the riser pipe and the collecting pipe are also mixed in the coal tar and form lumps of different sizes. These lumps are called tar residues. At present, mechanized clarification and separation equipment is generally used to separate tar residues from coal tar, and the separated tar residues are transported to the coal preparation process through a conveying device for secondary recycling as production raw materials. For example, tar residue is blended with coal for coking, and the tar residue and coal are simultaneously converted into coke, tar, and coke oven gas to achieve harmless treatment and resource utilization of tar residues.

[0003] During the crushing process of large tar residues, the tar residues that reach the particle size standard after crushing fall out through the filter screen by themselves. To prevent the tar residues from accumulating on the filter screen, a scraper is also needed to synchronously scrape the upper surface of the filter screen to make the tar residues pass through faster. However, because the tar residues are doped with fluids such as tar and ammonia water, they are easily adhered to the lower surface of the filter screen, and the scraper cannot treat the lower surface of the filter screen. After a large amount of the tar mixed with tar residues hardens on the lower surface of the filter screen, it will block the mesh holes, resulting in the inability of the tar residues to pass through. If conventional components such as a scraper are used to clean the lower surface of the filter screen, the tar mixed with tar residues is still easily hardened on it again, the scraper becomes thicker, and the filter screen is deformed by extrusion.

[0004] Therefore, in view of the above problems, a device can be designed to synchronously control the corresponding components to clean the lower surface of the filter screen by the driving force for crushing tar residues, and clean the corresponding cleaning components to prevent tar and tar residues from hardening on the lower surface of the filter screen and the cleaning components. Summary of the Invention

[0005] In order to overcome the problem that during the crushing process of tar residues, the mixed tar and tar residues are easily hardened on the filter screen, causing the mesh holes to be blocked and the tar residues unable to pass through.

[0006] The technical solution of the present invention is as follows: A crushing and processing device for tar residue recovery, comprising a crushing cylinder, an inlet end arranged at an upper position on one side of the crushing cylinder, an outlet end arranged at a lower position on the other side of the crushing cylinder, a driving component installed on the crushing cylinder, and a cutter head installed at the output end of the driving component. The tar residue enters the crushing cylinder through the inlet end and is discharged from the crushing cylinder through the outlet end. The driving component is used to drive the cutter head to rotate, and the cutter head is used to crush the tar residue. It also includes a screening and separating component installed inside the crushing cylinder. The screening and separating component includes an upper sieve mesh (mesh size 5 mm) and a lower sieve mesh (mesh size 4 mm) arranged from top to bottom; an upper scraping component is installed at the output end of the driving component, and the driving component is used to drive the upper scraping component to rotate on the upper surfaces of the upper sieve mesh and the lower sieve mesh. A lower scraping component and a transmission component are installed inside the crushing cylinder. The input end of the transmission component is connected to the output end of the upper scraping component, and the input end of the lower scraping component is connected to the output end of the transmission component. The driving component drives the lower scraping component to rotate on the lower surfaces of the upper sieve mesh and the lower sieve mesh through the upper scraping component and the transmission component; a cleaning component and an expansion component are installed on the lower scraping component. A conveying component is installed inside the crushing cylinder. The input end of the conveying component is connected to the transmission component, and the expansion component is communicated with the conveying component. The driving component controls the flow of the fluid medium between the conveying component and the expansion component through the upper scraping component and the transmission component. When the fluid medium (air, water, oil, etc. can be used) flows into or out of the expansion component, the expansion component expands or contracts (elastic, generating opposite forces on the cleaning component when expanding or contracting), and drives the cleaning component to swing reciprocally.

[0007] Preferably, the driving component includes a speed reducer installed on the crushing cylinder and a rotating shaft connected to the output end of the speed reducer. The cutter head is fixedly installed on the rotating shaft. The cutter head is arranged above the screening and separating component. The speed reducer drives the cutter head to rotate through the rotating shaft. The cutter head adopts a straight bevel structure with a sharp end, generating a shearing force on the tar residue to achieve crushing.

[0008] Preferably, the upper scraping component includes an assembly bushing fixedly installed on the rotating shaft, an internal gear ring arranged on the assembly bushing, and a plurality of scraping plates circumferentially and arrayedly installed on the assembly bushing. Scraping teeth are installed on the scraping plates. The speed reducer is used to drive the scraping plates to rotate around the rotating shaft. The assembly bushing can be fixed to the rotating shaft through bolt connectors. The distances between the scraping plates and the upper surfaces of the upper sieve mesh and the lower sieve mesh are both not greater than 5 mm. The scraping teeth are densely arranged on the scraping plates, and the distances between the ends of the scraping teeth and the upper surfaces of the upper sieve mesh and the lower sieve mesh are 2 - 3 mm.

[0009] Preferably, a support ring is installed on the inner wall of the crushing cylinder. The lower scraping component includes a carriage movably connected within the support ring, an external gear ring movably connected within the crushing cylinder, and a scraping roller with one end movably connected to the external gear ring and the other end movably connected to the carriage. The transmission component is connected between the external gear ring and the internal gear ring and transmits the power of the internal gear ring to the external gear ring. The surface of the scraping roller is in close contact with the lower surface of the upper screen and the lower surface of the lower screen. When the external gear ring rotates, the scraping roller rotates around its own central axis due to the frictional force with the screen component. When the scraping roller passes over the surface of the screen component, the sliding frictional force between the two plus the viscous force caused by partial tar adhesion can drive the scraping roller to rotate itself.

[0010] Preferably, a bracket is installed on the inner wall of the crushing cylinder. The transmission component includes a transmission gear movably connected to the bracket and a transmission disc fixedly connected to the transmission gear. The transmission gear meshes with the internal gear ring and the external gear ring, and the internal gear ring transmits power to the external gear ring through the transmission gear.

[0011] Preferably, the scraping roller includes a roller shaft with two ends movably connected to the external gear ring and the carriage respectively, and a heating element installed within the roller shaft (heating resistance wires can be used, and the heating temperature is set according to actual needs. Heat is transferred to the tar and tar residue through radiation to maintain fluidity). The roller shaft is made of a high thermal conductivity material (such as ceramics, heat-conducting alloys, etc.). The heating element is used to transfer heat to the roller shaft and radiate the heat into the tar through the roller shaft.

[0012] Preferably, an air cushion thin layer is coated on the roller shaft. There is a cavity between the air cushion thin layer (which can be made of a uniform-thickness silicone or rubber thin layer and can deform uniformly) and the surface of the roller shaft. When the heating element generates heat, the gas in the cavity expands and causes the air cushion thin layer to expand and deform.

[0013] Preferably, the cleaning component includes a clamping shaft with two ends movably connected to the external gear ring and the carriage respectively, a scraping blade fixedly connected to the clamping shaft (made of a thin plate material with toughness), and a fan plate fixedly connected to one end of the clamping shaft. The fan plate is arranged within the external gear ring. The end of the scraping blade is in close contact with the air cushion thin layer. The expansion part is fixedly connected to the fan plate. When the expansion part expands or contracts, it drives the clamping shaft to rotate through the fan plate.

[0014] Preferably, the conveying assembly includes a medium chamber mounted on the bracket, a conveying pipe with one end connected to the medium chamber, a plunger with one end movably connected inside the medium chamber, and a rocker arm with one end movably connected to the other end of the plunger. The other end of the rocker arm is movably connected to an eccentric position of the transmission disc. The other end of the conveying pipe communicates with the expansion member. The transmission gear drives the rocker arm to swing through the transmission disc, and the rocker arm drives the plunger to reciprocate inside the medium chamber. When the plunger reciprocates, the fluid medium flows into or out of the expansion member through the conveying pipe (a slip ring structure is provided between the outer gear ring and the conveying pipe. The slip ring and the outer gear ring can rotate relative to each other, and the existing mechanical sealing method or grease sealing is adopted between them. The fluid medium first enters the slip ring through the conveying pipe, then enters the outer gear ring, and finally flows into the expansion member).

[0015] Preferably, the expansion member includes an airbag. The airbag is arranged in the cavity of the outer gear ring and is connected to the fan plate. When the fluid medium flows in from the medium chamber, the airbag expands and pushes the fan plate to rotate to one side with the midline of the clamping shaft as the axis; when the fluid medium flows from the airbag into the medium chamber, the airbag contracts and pulls the fan plate to rotate to the other side with the midline of the clamping shaft as the axis.

[0016] Advantages of the present invention: 1. The upper scraping component (scraper + scraping teeth) cleans the upper surface of the screen, and the lower scraping component (scraping roller + air cushion thin layer) cleans the lower surface of the screen, thoroughly solving the adhesion problem of tar residue on the upper and lower surfaces of the filter screen, and significantly improving the filtration efficiency; 2. Through the hierarchical filtration of the upper screen (5 mm) and the lower screen (4 mm), precise control of the particle size of tar residue is achieved, and at the same time, large particles are prevented from blocking the outlet end; 3. The scraping roller is internally provided with a heating element (heating resistance wire) and an air cushion thin layer. The fluidity of tar on the lower surface of the screen is maintained through heat radiation and air cushion expansion, preventing the tar residue from caking and blocking the mesh holes; 4. By controlling the expansion / contraction of the expansion member (airbag) through the conveying assembly, the driving blade is driven to dynamically clean the surface of the scraping roller, efficiently shaking and separating the tar residue and tar, avoiding the secondary accumulation of tar residue on the scraping roller, and the cleaning effect is excellent; 5. The scraping blade is made of a tough thin plate material and contacts the surface of the scraping roller through elastic deformation when swinging, which can not only effectively remove the residual tar residue but also avoid equipment wear caused by hard scraping; 6. The power is transmitted to the outer gear ring through the transmission gear, and combined with the eccentric rocker arm to drive the plunger to reciprocate, precisely controlling the flow of the fluid medium in the expansion member, ensuring the stability and reliability of the cleaning action.

Detailed implementation manners

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please refer to Figures 1-11, the present invention provides an embodiment: a crushing treatment device for tar residue recovery, including a crushing cylinder 1, an inlet end 2 arranged at an upper position on one side of the crushing cylinder 1, an outlet end 3 arranged at a lower position on the other side of the crushing cylinder 1, a driving component installed on the crushing cylinder 1, and a cutter head 5 installed on the output end of the driving component. The tar residue enters the crushing cylinder 1 through the inlet end 2 and is discharged from the crushing cylinder 1 through the outlet end 3. The driving component is used to drive the cutter head 5 to rotate, and the cutter head 5 is used to crush the tar residue. It also includes a screening and separating component installed in the crushing cylinder 1. The screening and separating component includes an upper screen 601 and a lower screen 602 arranged from top to bottom. An upper scraping component is installed on the output end of the driving component, and the driving component is used to drive the upper scraping component to rotate on the upper surface of the upper screen 601 and the upper surface of the lower screen 602. A lower scraping component and a transmission component are installed in the crushing cylinder 1. The input end of the transmission component is connected to the output end of the upper scraping component, and the input end of the lower scraping component is connected to the output end of the transmission component. The driving component drives the lower scraping component to rotate on the lower surface of the upper screen 601 and the lower surface of the lower screen 602 through the upper scraping component and the transmission component. A cleaning component and an expansion member are installed on the lower scraping component. A conveying component is installed in the crushing cylinder 1. The input end of the conveying component is connected to the transmission component, and the expansion member is communicated with the conveying component. The driving component controls the flow of a fluid medium between the conveying component and the expansion member through the upper scraping component and the transmission component. When the fluid medium flows into or out of the expansion member, the expansion member expands or contracts and drives the cleaning component to swing reciprocally. A mixture of tar residue, ammonia water, and tar enters the crushing cylinder 1 through the inlet end 2. The driving component drives the cutter head 5, the upper scraping component, and the lower scraping component to rotate. The cutter head 5 crushes the tar residue. The upper scraping component cleans the upper surfaces of the upper filter screen and the lower filter screen, and the lower scraping component cleans the lower surfaces of the upper filter screen and the lower filter screen. By controlling the flow of the fluid medium in the conveying component into or out of the expansion member through the transmission component, the expansion member drives the cleaning component to clean the lower scraping component again.

[0021] Please refer to Figures 3-7 and Figure 9, in this embodiment, the driving assembly includes a speed reducer 401 installed on the crushing cylinder 1 and a rotating shaft 402 connected to the output end of the speed reducer 401. The cutter head 5 is fixedly installed on the rotating shaft 402. The cutter head 5 is arranged above the screening and separating assembly. The speed reducer 401 drives the cutter head 5 to rotate through the rotating shaft 402; the upper scraping assembly includes a mounting bushing 701 fixedly installed on the rotating shaft 402, an internal gear ring 702 arranged on the mounting bushing 701, and a plurality of scraping plates 703 circumferentially and arrayedly installed on the mounting bushing 701. Scraping teeth are installed on the scraping plates 703. The speed reducer 401 is used to drive the scraping plates 703 to rotate around the rotating shaft 402 as the axis; after the speed reducer 401 transmits power to the rotating shaft 402, it drives the cutter head 5 to rotate at a high speed and strike on the tar slag, so that the large tar slag is crushed into the required particle size. The tar slag that meets the particle size requirements falls through the screening and separating assembly. The scraping plates 703 and the scraping teeth rotate following the fixed installation of the mounting bushing 701 and the rotating shaft 402, and have the effect of stirring and further crushing the tar slag on the upper filter screen and the lower filter screen (the shearing effect of the scraping teeth on the tar slag).

[0022] Please refer to Figures 3-10, in this embodiment, a support ring 801 is installed on the inner wall of the crushing cylinder 1. The lower scraping component includes a carriage 802 movably connected within the support ring 801, an external gear ring 803 movably connected within the crushing cylinder 1, and a scraping roller 804 with one end movably connected to the external gear ring 803. The other end of the scraping roller 804 is movably connected to the carriage 802. The transmission component is connected between the external gear ring 803 and the internal gear ring 702 and transmits the power of the internal gear ring 702 to the external gear ring 803. The surface of the scraping roller 804 is in close contact with the lower surface of the upper screen 601 and the lower surface of the lower screen 602. When the external gear ring 803 rotates, the scraping roller 804 rotates around its own central axis due to the frictional force with the screen assembly; a bracket 901 is installed on the inner wall of the crushing cylinder 1. The transmission component includes a transmission gear 902 movably connected to the bracket 901 and a transmission disc 903 fixedly connected to the transmission gear 902. The transmission gear 902 meshes with the internal gear ring 702 and the external gear ring 803, and the internal gear ring 702 transmits the power to the external gear ring 803 through the transmission gear 902; the scraping roller 804 includes a roller shaft 8001 with two ends movably connected to the external gear ring 803 and the carriage 802 respectively, and a heating element 8002 installed within the roller shaft 8001. The roller shaft 8001 is made of a high thermal conductivity material. The heating element 8002 is used to transfer heat to the roller shaft 8001, and the heat is radiated into the tar through the roller shaft 8001; an air cushion thin layer 8003 is coated on the roller shaft 8001, and a cavity is provided between the air cushion thin layer 8003 and the surface of the roller shaft 8001. When the heating element 8002 generates heat, the gas in the cavity expands, causing the air cushion thin layer 8003 to expand and deform; the transmission gear 902 transmits the power of the speed reducer 401 to the external gear ring 803 through the meshing connection with the external gear ring 803 and the internal gear ring 702. In cooperation with the movable connection between the carriage 802 and the support ring 801 (in actual use, rolling elements can be densely arranged in the groove of the support ring 801 to prevent tar residues and dust from entering), the scraping roller 804 rotates past the lower surfaces of the upper filter screen and the lower filter screen. While passing, it rotates itself through sliding friction, scraping off the tar and tar residues adhering to the lower surfaces of the upper filter screen and the lower filter screen. The heating element 8002 is energized to generate heat (in actual use, a resistance wire is usually used), and the heat is transferred into the cavity between the air cushion thin layer 8003 and the surface of the roller shaft 8001 through the roller shaft 8001. The air cushion thin layer 8003 expands due to gas expansion and is in close contact with the lower surfaces of the upper filter screen and the lower filter screen (this structure of the expansion of the air cushion thin layer 8003 will not cause excessive extrusion force on the upper filter screen and the lower filter screen to cause deformation).

[0023] Please refer to Figures 3-11, in this embodiment, the cleaning assembly includes a clamping shaft 1001 whose two ends are respectively movably connected to the external gear ring 803 and the carriage 802, a wiper blade 1002 fixedly connected to the clamping shaft 1001, and a sector plate 1003 fixedly connected to one end of the clamping shaft 1001. The sector plate 1003 is arranged inside the external gear ring 803. The end of the wiper blade 1002 is in close contact with the air cushion layer 8003. The expansion member is fixedly connected to the sector plate 1003. When the expansion member expands or contracts, it drives the clamping shaft 1001 to rotate through the sector plate 1003; the conveying assembly includes a medium chamber 1101 installed on the bracket 901, a conveying pipe 1102 with one end connected to the medium chamber 1101, a plunger 1103 with one end movably connected inside the medium chamber 1101, and a rocker arm 1104 with one end movably connected to the other end of the plunger 1103. The other end of the rocker arm 1104 is movably connected to an eccentric position of the transmission disc 903. The other end of the conveying pipe 1102 is communicated with the expansion member. The transmission gear 902 drives the rocker arm 1104 to swing through the transmission disc 903. The rocker arm 1104 drives the plunger 1103 to reciprocate inside the medium chamber 1101. When the plunger 1103 reciprocates, the fluid medium flows into or out of the expansion member through the conveying pipe 1102; the expansion member includes an airbag 1201. The airbag 1201 is arranged inside the cavity of the external gear ring 803 and is connected to the sector plate 1003. When the fluid medium flows into the airbag 1201 from the medium chamber 1101, the airbag 1201 expands and pushes the sector plate 1003 to rotate to one side with the center line of the clamping shaft 1001 as the axis; when the fluid medium flows from the airbag 1201 into the medium chamber 1101, the airbag 1201 contracts and pulls the sector plate 1003 to rotate to the other side with the center line of the clamping shaft 1001 as the axis; when the transmission disc 903 rotates, it transmits power to the rocker arm 1104. Through the swing of the rocker arm 1104 (due to the eccentric arrangement relationship with the transmission disc 903), the plunger 1103 reciprocates inside the medium chamber 1101, and then the fluid medium enters the expansion member (in this solution, the expansion member uses an airbag 1201, so the fluid medium is air. In actual application, a hollow slip ring 1105 is movably connected to the external gear ring 803. One end of the conveying pipe 1102 is connected to the slip ring 1105. The external gear ring 803 rotates relative to the slip ring 1105, which does not affect the transmission of the medium in the conveying pipe 1102. A mechanical seal, a magnetic fluid seal or a grease seal is used between the external gear ring 803 and the slip ring 1105 to prevent the fluid medium from overflowing). The expansion and contraction of the expansion member generate forces in different directions on the sector plate 1003, causing the clamping shaft 1001 to drive the wiper blade 1002 to rotate and swing rapidly (reciprocally swing a certain angle, determined by the expansion and contraction amount of the expansion member), and using the elasticity and toughness of the wiper blade 1002 itself, it deforms when swinging past the scraping roller 804, and throws out the tar and tar slag.

[0024] Working principle: The mixture of large tar residues, ammonia water and tar separated by pretreatment enters the crushing cylinder 1 from the inlet end 2. The reducer 401 drives the cutter head 5 to rotate through the rotating shaft 402, crushing the tar residues. The qualified tar residues pass through the upper screen 601 and the lower screen 602 in sequence and are discharged from the outlet end 3 (in actual use, it will be assisted by equipment such as a screw conveyor for discharge); During the rotation of the rotating shaft 402, it drives the assembled bushing 701 fixed to it to rotate, thereby causing the scraper 703 to rotate on the upper surface of the upper screen 601 and the upper surface of the lower screen 602. The scraper 703 and the scraping teeth on its upper part are used to push the tar residues to rotate, assisting the cutter head 5 in crushing, and enabling the tar residues to pass through the mesh holes of the upper screen 601 and the lower screen 602 faster; The internal gear ring 702 transmits power to the external gear ring 803 through the transmission gear 902, causing the scraping roller 804 to rotate synchronously around the rotating shaft 402. When the heating element 8002 is energized and heated, the cavity gas between the air cushion layer 8003 and the roller 8001 expands, causing the air cushion layer 8003 to expand, so that the surface of the air cushion layer 8003 contacts the lower surface of the upper screen 601 and the lower surface of the lower screen 602. Through the frictional action with the upper screen 601 and the lower screen 602, the scraping roller 804 rotates and rolls by itself; At the same time, the transmission gear 902 transmits power to the plunger 1103 through the rocker arm 1104, causing the plunger 1103 to move in the medium cavity 1101, enabling the fluid medium to flow between the medium cavity 1101 and the expansion part through the delivery pipe 1102. While the expansion part expands and contracts, it generates forces in different directions on the fan plate 1003, causing the clamping shaft 1001 to drive the scraper 1002 to swing back and forth. When it contacts the surface of the scraping roller 804, it undergoes bending and tensile deformation. When scraping the adhered tar, it will also bounce off the tar through its own elastic recovery action (the scraper 1002 swings during the rotation of the scraping roller 804 itself, so it can clean the entire surface of the scraping roller 804), achieving a cleaning effect.
