Description

Technical Field

[0001] This invention relates to the field of ammonia clarification technology, specifically to a mechanized clarification tank oil filter assembly. Background Technology

[0002] After the raw coal gas is produced, the gas in the bridge pipe is rich in tar droplets and compounds containing ammonia and sulfur. Under the suction of the Roots blower, the hot-loop ammonia water return also contains a large amount of coal meal and coke meal. To meet the gas requirements of the oil plant, the hot-loop ammonia water return must be purified and impurities removed, thus giving rise to sedimentation tanks for precipitation. Mechanized ammonia water clarification tanks are equipment used by coking plants to separate ammonia water, tar, and tar residue. Under the action of gravity, it is mainly divided into three layers: an ammonia water layer, a coal tar layer, and a tar residue layer. A layer of clear oil also floats on the surface of the ammonia water layer.

[0003] The existing floating oil filter screens in the mechanized clarifier consist of two sets of 1.7m x 0.55m x 3mm filter screens with a 5mm x 5mm aperture. These screens can only filter flocculent impurities floating on top of the ammonia water when coke oven production is abnormal. They are ineffective at filtering the floating oil on the upper layer of the ammonia water, easily leading to high oil content in the circulating ammonia water and residual ammonia water. This increases the load on the ammonia water filter, the amount of tar residue discharged from the ammonia stripping tower, the likelihood of scaling on the ammonia stripping tower trays and bubble caps, the labor intensity of workers, and the risk of clogging of the circulating ammonia water spray nozzles. It also affects the atomization effect of the circulating ammonia water spray, easily leading to higher gas temperatures before the primary cooler, and insufficient tar recovery, thus affecting tar production and yield. Therefore, there is an urgent need for a new floating oil filter screen assembly for the mechanized clarifier to solve these problems. Summary of the Invention

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-9 This invention provides a technical solution for a mechanized clarifier oil flotation filter assembly: a mechanized clarifier oil flotation filter assembly includes a sedimentation tank 1, a top plate 2 fixedly installed on the upper part of the inner side wall of the sedimentation tank 1, a filter plate 3 arranged below the top plate 2, a side plate 4 fixedly installed on the upper part of the outer side wall of the filter plate 3, the filter plate 3 being hollow, and a piston plate 5 slidably installed on the bottom surface of the inner cavity of the filter plate 3, and further includes: Weighing mechanism 6 is installed around the upper surface of side plate 4 and is used to adjust the height of filter screen plate 3. Unblocking mechanism 7 is installed on the left and right side walls of filter screen plate 3. Unblocking mechanism 7 is used to scrape the outer wall of filter screen plate 3. Oil lifting mechanism 8 is located on the upper end face of piston plate 5 and is used to remove floating oil from the inner cavity of filter screen plate 3. The liquid addition mechanism 9 is located on the upper end face of the top plate 2 and is used to add sodium carbonate solution into the sedimentation tank 1.

[0021] Furthermore, the weighing mechanism 6 includes a positioning screw 61 rotatably mounted around the lower end face of the top plate 2, and a weighing spring 62 wound around the side wall of the positioning screw 61. A limit plate 63 is fixedly mounted on the lower part of the outer side wall of each positioning screw 61. A right-angle bracket 64 is rotatably mounted on the side wall of the limit plate 63. A first bevel gear 65 is rotatably mounted on the top surface of the inner cavity of the right-angle bracket 64, and a second bevel gear 66 is rotatably mounted on the side surface of the inner cavity of the right-angle bracket 64. One end of the weighing spring 62 is fixedly installed on the lower end face of the top plate 2, and the other end of the weighing spring 62 is fixedly installed on the upper end face of the side plate 4. The positioning screw 61 is threadedly connected to the side plate 4. The thread helix angle of the positioning screw 61 is greater than the equivalent friction angle of the side plate 4. The first bevel gear 65 is fixedly installed on the lower end face of the positioning screw 61, and the first bevel gear 65 is connected to the second bevel gear 66.

[0022] It should be noted that, through the filter holes 31 on the left and right side walls of the filter screen plate 3, the floating oil in the clear oil layer can enter the inner cavity of the filter screen plate 3 through the filter holes 31. Since the cross-section of the filter holes 31 is V-shaped and the diameter of the holes on the inner side wall of the filter holes 31 is smaller than the diameter of the holes on the outer side wall of the filter holes 31, when the floating oil enters the inner cavity of the filter screen plate 3, it will be difficult for it to flow out again. As the floating oil capacity in the filter screen plate 3 increases, the filter screen plate 3 will pull the side plate 4 downward. At this time, the weighing spring 62 will be stretched. Since the thread helix angle of the positioning screw 61 is greater than the equivalent friction angle of the side plate 4, when the side plate 4 moves downward, the positioning screw 61 will drive the first bevel gear 65 to rotate.

[0023] Furthermore, the unblocking mechanism 7 includes a bidirectional threaded groove rod 71 rotatably mounted between the front and rear right-angle frames 64, and a movable seat 72 slidably mounted on the side wall of the bidirectional threaded groove rod 71. A limit pin 711 is slidably mounted on the inner cavity side wall of the bidirectional threaded groove rod 71. A scraper 74 is fixedly mounted on the side wall of the movable seat 72 via a connecting rod 73. A brush head 75 is fixedly mounted on the inner side wall of the scraper 74. The limiting pin 711 is fixedly installed in the inner cavity of the movable seat 72. The movable seat 72 slides on the side wall of the filter plate 3. The bidirectional threaded groove rod 71 is fixedly connected to the second bevel gear 66 on the front and rear sides. The positioning screws 61 on the front and rear sides have opposite spiral directions. The brush head 75 is in contact with the side wall of the filter plate 3. Filter holes 31 are opened on the left and right side walls of the filter plate 3. The cross-section of the filter hole 31 is V-shaped, and the diameter of the hole on the inner side wall of the filter hole 31 is smaller than the diameter of the hole on the outer side wall of the filter hole 31.

[0024] It should be noted that the first bevel gear 65 is connected to the second bevel gear 66. At this time, the second bevel gear 66 can drive the bidirectional threaded groove rod 71 to rotate. Since the moving seat 72 is in contact with the side wall of the filter screen plate 3, under the limiting constraint of the limiting pin 711, the moving seat 72 can drive the connecting rod 73 to make the scraping plate 74 move left and right. The brush head 75 can output to the filter holes 31 provided on the side wall of the filter screen plate 3 to ensure the quality of the entire filter screen plate 3 in adsorbing floating oil.

[0025] Furthermore, the oil lifting mechanism 8 includes support plates 81 fixedly installed on the front and rear sides of the right side of the upper end face of the top plate 2, and a transmission worm gear 82 rotatably installed between the support plates 81.

Heaters 88 are fixedly installed on the left and right sides of the upper part of the inner cavity of the filter screen plate 3. The transmission worm 82 is meshed with the transmission worm wheel 84, the oil lifting screw 85 is connected through the bushing 83, the oil lifting screw 85 is fixedly installed in the middle of the upper end face of the piston plate 5, the limiting rod 86 is fixedly installed on the front and rear sides of the upper end face of the piston plate 5, the output shaft end of the oil lifting motor 87 is fixedly connected to the transmission worm 82, the front and rear end faces of the filter screen plate 3 are provided with oil leakage grooves 32, the oil leakage grooves 32 are set downwards, the oil leakage grooves 32 are located below the heater 88, and the front and rear end faces of the filter screen plate 3 are fixedly installed with oil guide pipes 89 that are connected to the oil leakage grooves 32.

[0026] It should be noted that the user can start the oil lifting motor 87 to make the transmission worm 82 rotate. Since the transmission worm 82 is meshed with the transmission worm wheel 84, the transmission worm wheel 84 will rotate on the upper end face of the bushing 83. The oil lifting screw 85 is threadedly connected to the transmission worm wheel 84 and fixedly connected to the piston plate 5. Under the limiting constraint of the front and rear limit rods 86, the oil lifting screw 85 can drive the piston plate 5 to move to the upper part of the inner cavity of the filter screen plate 3, lifting the collected floating oil upward. At this time, the user can turn on the heater 88 to heat the upper part of the filter screen plate 3 to melt the floating oil. The melted floating oil is discharged from the oil guide pipe 89 through the downward inclined oil leakage groove 32, so as to collect the floating oil and restore the filter screen plate 3 to its initial position to intercept and collect the floating oil in the clear oil layer again.

[0027] Furthermore, the liquid filling mechanism 9 includes an extension rod 91 fixedly installed on the left end face of the transmission worm gear 82, and a cam block 92 fixedly installed on the side wall of the extension rod 91. An accumulator box 93 is fixedly installed on the rear side of the upper end face of the top plate 2. An accumulator plate 94 is slidably installed in the inner cavity of the accumulator box 93. An accumulator rod 95 is fixedly installed on the side wall of the accumulator plate 94. An accumulator spring 96 is wound on the side wall of the accumulator rod 95. Cam block 92 fits against the side wall of accumulator plate 94, accumulator plate 94 is slidably connected to accumulator box 93, one end of accumulator spring 96 is fixedly installed on the side wall of accumulator plate 94, and the other end is fixedly installed on the inner cavity side wall of accumulator box 93, spray plate 97 is fixedly installed on the lower end face of top plate 2, and liquid storage box 98 is fixedly installed on the front side of the upper end face of top plate 2; An inlet pipe 981 is fixedly installed on the bottom surface of the inner cavity of the liquid storage box 98. An inlet hole is opened on the lower part of the outer side wall of the inlet pipe 981. The other end of the inlet pipe 981 is fixedly connected to the accumulator box 93. A one-way water valve with an outlet to the inner cavity of the accumulator box 93 is provided in the inner cavity of the inlet pipe 981. An outlet pipe 931 connected to the spray plate 97 is fixedly installed on the lower end face of the accumulator box 93. A one-way water valve with an outlet to the inner cavity of the spray plate 97 is provided in the inner cavity of the outlet pipe 931. The outlet pipe 931 is connected through the top plate 2.

[0028] It should be noted that when the transmission worm gear 82 rotates, the extension rod 91 fixedly installed at its end can drive the cam block 92 to rotate. Since the cam block 92 is in contact with the side wall of the accumulator rod 95, under the action of the accumulator spring 96, the accumulator rod 95 can drive the accumulator plate 94 to move back and forth in the inner cavity of the accumulator box 93. When the volume of the rear cavity of the accumulator box 93 increases, the sodium carbonate solution in the inner cavity of the storage box 98 can enter the inner cavity of the accumulator box 93 through the inlet pipe 981 to replenish the sodium carbonate solution in the inner cavity of the accumulator box 93. When the volume of the rear cavity of the accumulator box 93 decreases, the sodium carbonate solution in the inner cavity of the accumulator box 93 can enter the inner cavity of the spray plate 97 through the outlet pipe 931. Finally, the sodium carbonate solution will be sprayed into the sedimentation tank 1 to promote the efficiency and quality of kerosene sedimentation in the sedimentation tank 1.

[0029] Working principle: When kerosene is settled in sedimentation tank 1, the floating oil in the clear oil layer can enter the inner cavity of filter screen plate 3 through the filter holes 31 on the left and right side walls of the filter screen plate 3. Since the cross-section of the filter holes 31 is V-shaped and the diameter of the holes on the inner side wall of the filter holes 31 is smaller than the diameter of the holes on the outer side wall of the filter holes 31, it will be difficult for the floating oil to flow out after entering the inner cavity of the filter screen plate 3. As the volume of floating oil in the filter screen plate 3 increases, the filter screen plate 3 will pull the side plate 4 downward. At this time, the weighing spring 62 will be stretched, and the thread helix angle of the positioning screw 61 will be greater than that of the side plate. With an equivalent friction angle of 4, when the side plate 4 moves downward, the positioning screw 61 will drive the first bevel gear 65 to rotate. The first bevel gear 65 is connected to the second bevel gear 66. At this time, the second bevel gear 66 can drive the bidirectional threaded groove rod 71 to rotate. Since the moving seat 72 is in contact with the side wall of the filter screen plate 3, under the limiting constraint of the limiting pin 711, the moving seat 72 can drive the connecting rod 73 to make the scraping plate 74 move left and right. The brush head 75 can output to the filter holes 31 set on the side wall of the filter screen plate 3 to ensure the quality of the entire filter screen plate 3 in adsorbing floating oil. It should be noted that when the filter plate 3 moves downward, the bottom of the filter plate 3 can be placed at the ammonia water layer to adsorb the floating oil remaining at the top of the ammonia water layer, so as to ensure the quality of subsequent ammonia water recycling. The user can start the oil lifting motor 87 to make the transmission worm 82 rotate. Since the transmission worm 82 is meshed with the transmission worm wheel 84, the transmission worm wheel 84 will rotate on the upper end face of the bushing 83. The oil lifting screw 85 is threadedly connected to the transmission worm wheel 84 and fixedly connected to the piston plate 5. Under the limiting constraint of the front and rear limit rods 86, the oil lifting screw 85 can drive the piston plate 5 to move to the upper part of the inner cavity of the filter screen plate 3 to lift the collected floating oil upward. At this time, the user can turn on the heater 88 to heat the upper part of the filter screen plate 3 to melt the floating oil. The melted floating oil can be discharged from the oil guide pipe 89 through the downward inclined oil leakage groove 32 to collect the floating oil. At the same time, the filter screen plate 3 returns to its initial position to intercept and collect the floating oil in the clear oil layer again. When the transmission worm gear 82 rotates, the extension rod 91 fixedly installed at its end can drive the cam block 92 to rotate. Since the cam block 92 is in contact with the side wall of the accumulator rod 95, under the action of the accumulator spring 96, the accumulator rod 95 can drive the accumulator plate 94 to move back and forth in the inner cavity of the accumulator box 93. When the volume of the rear cavity of the accumulator box 93 increases, the sodium carbonate solution in the inner cavity of the storage box 98 can enter the inner cavity of the accumulator box 93 through the inlet pipe 981 to replenish the sodium carbonate solution in the inner cavity of the accumulator box 93. When the volume of the rear cavity of the accumulator box 93 decreases, the sodium carbonate solution in the inner cavity of the accumulator box 93 can enter the inner cavity of the spray plate 97 through the outlet pipe 931. Finally, the sodium carbonate solution will be sprayed into the sedimentation tank 1 to promote the efficiency and quality of kerosene sedimentation in the sedimentation tank 1.
