Description

Technical Field

[0001] This utility model relates to the field of chemical technology, specifically to a waste clay regeneration device. Background Technology

[0002] In the refining process of products such as paraffin wax, Fischer-Tropsch wax, and lubricating oil base oils, 1% to 5% of the material is typically used for refining. The waste bleaching clay after refining generally contains 20% to 50% of the material. For many years, most chemical plants and oil refineries have directly mixed the waste bleaching clay from refining with coal as fuel or disposed of it as waste through landfill, failing to achieve full and rational utilization. If the waste bleaching clay used in refining is not treated promptly, it will not only pollute the environment and endanger groundwater quality, but also, if the oil it contains is a light component, it is prone to spontaneous combustion upon contact with air, causing fires. Recycling and reusing waste bleaching clay can reuse the waste bleaching clay generated in factories, prevent soil pollution caused by indiscriminate dumping, and reduce the factory's expenses for purchasing fresh bleaching clay and disposing of waste bleaching clay solid waste.

[0003] Therefore, the effective recycling of waste bleaching clay is an urgent problem to be solved. In existing technologies, the regeneration process of bleaching clay mostly adopts solvent extraction combined with other auxiliary methods (centrifugation, heat treatment, ultrasonic treatment, acidification treatment, etc.), which is complex and costly.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-5 This utility model provides a technical solution: a waste bleaching clay recycling device, including a cylinder 1. A first reduction motor 2 is bolted to the left side of the cylinder 1. When the first reduction motor 2 is started, a crossbar 3 is fixedly connected to the output end of the first reduction motor 2 through the cylinder 1. The first reduction motor 2 drives the crossbar 3 to rotate clockwise. A guide blade 4 is fixedly connected to the outer wall of the crossbar 3. The clockwise rotation of the crossbar 3 pushes the waste bleaching clay into the inner cavity of the recycling furnace 6 through the guide blade 4. The waste bleaching clay is in the recycling furnace 6. A crushing device is set on the top left side of the cylinder 1.

[0031] The crushing device includes a housing 17, a feed inlet 19, a second reduction motor 18, a first gear 28, a first rotating rod 33, a first crushing tooth 29, a second gear 30, a second rotating rod 32, a second crushing tooth 31, a first discharge valve 21, and a second discharge valve 5.

[0032] A box 17 is located on the top left side of the cylinder 1. A feed inlet 19 is opened at the top of the box 17, through which waste bleaching clay is added to the device. A second reduction motor 18 is bolted to the right side of the box 17. The second reduction motor 18 rotates clockwise. A first gear 28 is welded through the box 17 to the second reduction motor 18, driving the first gear 28 to rotate clockwise. A first rotating rod 33 is welded to the left side of the first gear 28.

A second rotating rod 32 is welded to the left side of the second gear 30. A second crushing tooth 31 is fixedly connected to the outer wall of the second rotating rod 32. The clockwise movement of the second gear 18, through the cooperation of the first gear 28 and the second gear 30, causes the second rotating rod 32 and the second crushing tooth 31 to move counterclockwise, thereby realizing the crushing of waste white clay. A first discharge valve 21 is installed at the bottom end of the box 17. The first discharge valve 21 is used to connect the box 17 and the cylinder 1.

A protective gas inlet valve 7 and an air inlet valve 8 are provided on one side of the regeneration furnace 6. The regeneration furnace 6 is connected to the protective gas inlet valve 7 and the air inlet valve 8, which are used to introduce air or protective gas into the regeneration furnace 6. During the regeneration stage, protective gas is introduced. The bleaching clay and oil are separated by heating in the protective gas atmosphere. The protective gas can prevent the oil from being oxidized. The bottom end of the regeneration furnace 6 is provided with a regenerated bleaching clay discharge port 10.

[0035] As a preferred embodiment, further, an oil outlet pipe 14 is provided on one side of the regeneration furnace 6, and a first valve 11 is provided on the outer wall of the oil outlet pipe 14.

After separating the clay and oil, air is introduced, and the remaining oil in the regeneration furnace 6 is removed by combustion.

[0036] As a preferred embodiment, the outer wall of the regeneration furnace 6 is provided with a gas guide pipe 12, the outer wall of the gas guide pipe 12 is provided with a second valve 13, and the other end of the gas guide pipe 12 is provided with a waste gas filtration device, which includes a first filter box 23, a nozzle 34, a water pump 26, a second filter box 22, a first water pipe 27, a suction fan 25, a second water pipe 20, a water inlet valve 35, an exhaust valve 36, and a water outlet valve 24.

[0037] A first filter box 23 is installed at the other end of the air duct 12. A nozzle 34 is installed at the top of the inner cavity of the first filter box 23. A water pump 26 is bolted to the outer wall of the top of the first filter box 23. One end of the water pump 26 is connected to the nozzle 34 through a conduit. A second filter box 22 is fixedly connected to the right side of the first filter box 23. The other end of the water pump 26 is connected to one end of a first water pipe 27 through a conduit. The first water pipe 27 penetrates the outer wall of the top right side of the second filter box 22, and its other end extends into the bottom of the inner cavity of the second filter box 22. A suction fan 25 is bolted to the outer wall of the top right side of the first filter box 23. One end of the suction fan 25 is connected to the inner cavity of the first filter box 23 through a conduit. The other end of the suction fan 25 is connected to one end of a second water pipe 20 through a conduit. The second water pipe 20 penetrates the outer wall of the top left side of the second filter box 22. The other end of the filter extends into the bottom of the inner cavity of the second filter box 22. The exhaust gas enters the first filter box 23 through the air guide pipe 12 and the second valve 13. The water pump 26 draws in filtered water containing filtrate inside the second filter box 22 and sprays the water onto the exhaust gas through the nozzle 34. The harmful substances dissolve in the filtrate. Since the bottom of the second filter box 22 is connected to the bottom of the first filter box 23, the filtrate can be recycled to filter the harmful air, saving filtrate and allowing the harmful substances to be fully absorbed. The filtrate can be recycled to filter the harmful air. A water inlet valve 35 is fixedly connected to the outer wall of the top right side of the second filter box 22. An exhaust valve 36 is provided on the outer wall of the center right side of the second filter box 22. A water outlet valve 24 is provided on the outer wall of the bottom right side of the second filter box 22. The bottom of the first filter box 23 is connected to the bottom of the second filter box 22.

[0038] As a preferred option, the outer side of the regeneration furnace 6 is equipped with a waste heat recovery unit, which facilitates the recovery of heat for further heating of the waste clay.

[0039] As a preferred option, the regeneration furnace 6 is further equipped with a temperature sensor, which facilitates the monitoring of the temperature inside the regeneration furnace 6.

[0040] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without explaining the electrical control.

[0041] In use, connect the external power supply to the device, and add the waste bleaching clay into the device through the feed inlet 19. This causes the second reduction motor 18 to rotate clockwise, which in turn drives the first gear 28 to rotate clockwise. The clockwise rotation of the first gear 28 causes the first rotating rod 33 and the first crushing tooth 29 to move clockwise. The clockwise movement of the second reduction motor 18, through the cooperation of the first gear 28 and the second gear 30, causes the second rotating rod 32 and the second crushing tooth 31 to move counterclockwise, thus crushing the waste bleaching clay. At this time, open the first discharge valve 21, and the waste bleaching clay enters the cylinder. 1. At this time, the first reduction motor 2 is started. The first reduction motor 2 drives the crossbar 3 to rotate clockwise. The clockwise rotation of the crossbar 3 pushes the waste bleaching clay into the inner cavity of the regeneration furnace 6 through the guide vanes 4. The waste bleaching clay is in the regeneration furnace 6. A heater 9 is set on the outer periphery of the regeneration furnace 6. A temperature sensor can be set inside the regeneration furnace 6. The regeneration furnace 6 is connected to the protective gas inlet valve 7 and the air inlet valve 8, which are used to regenerate the furnace 6 with air or protective gas. During the regeneration stage, protective gas is introduced. Heating under the protective gas atmosphere separates the bleaching clay and oil. The protective gas can prevent the oil from being oxidized. The discharge end of the regeneration furnace 6 is equipped with a regenerated bleaching clay discharge port and an oil outlet. The regenerated bleaching clay discharge port is used to discharge the regenerated bleaching clay from the regeneration furnace 6. The oil and gas generated during the regeneration process are introduced into the oil and gas separator 15 through the regeneration furnace 6. The oil and gas separator 15 separates the oil and gas to obtain recovered oil. The protective gas source is a nitrogen source. The protective gas can also be other inert gases, such as helium. After separating the clay and oil, air is introduced, and the remaining oil in the regeneration furnace 6 is removed by combustion. At this time, the exhaust gas enters the first filter box 23 through the air guide pipe 12 and the second valve 13. The water pump 26 draws in filtered water containing filtrate inside the second filter box 22 and sprays the water onto the exhaust gas through the nozzle 34. The harmful substances dissolve in the filtrate. Since the bottom of the second filter box 22 is connected to the bottom of the first filter box 23, the filtrate can be recycled to filter the harmful air, saving filtrate and allowing the harmful substances to be fully absorbed. The design structure is reasonable, highly applicable, and beneficial for widespread use.
