Description

Technical Field

[0001] This invention relates to the field of pretreatment equipment, and more particularly to a pretreatment equipment and control method for producing hydrogenated C9 petroleum resin. Background Technology

[0002] Hydrogenated C9 petroleum resin is a thermoplastic resin made by polymerizing C9, a byproduct of ethylene cracking, in the presence of a catalyst, or by copolymerizing it with aldehydes, aromatics, and olefins.

[0003] Some patent documents related to pretreatment equipment are disclosed in the prior art. Chinese patent with publication number CN219111612U discloses a pretreatment device for raw materials for petroleum resin production, which belongs to the field of petroleum resin technology. The pretreatment device for raw materials for petroleum resin production includes a reaction tank. The reaction tank is equipped with a preheating chamber and a stirring chamber. The reaction tank is equipped with a first filter plate and a second filter plate. The reaction tank is equipped with a heating device. The upper end of the reaction tank is equipped with a feed inlet.

[0004] In the production of petroleum resin, the raw materials need to be preheated and melted to separate the impurities that are difficult to melt. Existing technologies mostly use screen separation, but impurities tend to accumulate on the screen surface, affecting the separation effect. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art by proposing a pretreatment device and control method for producing hydrogenated C9 petroleum resin.

[0006] To achieve the above objectives, in a first aspect, the present invention provides a pretreatment apparatus for producing hydrogenated C9 petroleum resin, comprising:

[0007] A reaction vessel, wherein the reaction vessel has a reaction chamber;

[0008] A separation cylinder is rotatably disposed inside a reaction vessel. A drive assembly is disposed on the outside of the separation cylinder to drive the separation cylinder to rotate. Multiple separation sieve holes are opened on the surface of the separation cylinder. A heating assembly is disposed inside the separation cylinder.

[0009] An oil draining cylinder is fixed on the surface of the reaction vessel. One end of the oil draining cylinder is rotatably connected to a separation cylinder. An impurity discharge groove is provided between the oil draining cylinder and the separation cylinder. Multiple oil draining holes are opened on the surface of the oil draining cylinder.

[0010] The separator is inclined, with a feed pipe at the higher end and the lower end connected to the oil draining cylinder.

[0011] A lifting assembly is disposed inside the separation cylinder. The lifting assembly has multiple lifting chambers, and the bottom surface of each lifting chamber has multiple drainage holes.

[0012] When the raw material is not fully melted, the lifting chamber is in an open state, and the condensed raw material and impurities leak out from the opening. When the raw material is fully melted, the lifting chamber switches to a closed state, and the molten raw material flows down from the drain hole. The lifting chamber lifts the impurities to the impurity discharge tank position.

[0013] It should be noted that the heating component is a heating rod, which is fixed inside the separation cylinder;

[0014] The drive assembly includes a motor and a first gear. The motor is fixed to the inner wall of the reaction vessel, and the first gear is sleeved and fixed to the outer wall of the separation cylinder. A second gear is fixed to the end of the output shaft of the motor, and the second gear meshes with the first gear.

[0015] The end of the feed pipe is fixed with a mounting plate, and the mounting plate is rotatably connected to the separation cylinder;

[0016] Specifically, the raw material is added into the separator. After the raw material is added, the overall height of the raw material is lower than the height of the impurity discharge tank, thereby preventing the raw material from directly entering the impurity discharge tank.

[0017] The reaction vessel is heated by the heating component, which melts the raw material in the separation cylinder. The melted raw material flows into the reaction chamber through the separation sieve holes on the surface of the separation cylinder.

[0018] Multiple ribs are fixed on the inner wall of the separator. The separator is slowly driven to rotate by the drive mechanism. During the rotation, the ribs stir and mix the raw materials inside the separator to prevent insoluble impurities from settling and accumulating at the bottom, which would affect the separation effect.

[0019] Furthermore, by setting up a lifting component, the lifting component can rotate synchronously with the separation cylinder. When the raw material is first heated, some of the condensed raw material has not yet completely melted. At this time, the lifting chamber of the lifting component is in an open state. As the lifting component rotates with the separation cylinder, the condensed raw material and impurities can leak out from the opening. The lifting component stirs the raw material, further accelerating the melting speed of the condensed raw material.

[0020] When the raw material is fully melted after heating for a certain period of time, the opening of the lifting chamber closes, and the molten raw material flows down from the drain hole, thereby lifting only the impurities to the impurity discharge tank and discharging them, further reducing the impact of impurity accumulation on the pretreatment of raw materials.

[0021] By tilting the separation cylinder, impurities can automatically flow to the lifting mechanism under the action of gravity. On the one hand, this improves the processing efficiency of the lifting mechanism. On the other hand, the accumulation of impurities at the end of the separation cylinder also helps to avoid the situation where impurities accumulate randomly and cause large-area obstruction of the separation screen.

[0022] Preferably, the reaction vessel is further provided with a control component, the control component including:

[0023] A temperature sensor is fixed inside the separation cylinder and is used to detect the temperature inside the separation cylinder to determine whether the condensed raw material has completely melted.

[0024] The controller is located outside the reaction vessel. After the condensed raw materials have completely melted, the controller is used to control the start of the lifting assembly.

[0025] Preferably, the lifting component includes:

[0026] Equipment cylinder, the equipment cylinder being disposed at the end of the separation cylinder;

[0027] The baffles are evenly distributed on the surface of the equipment cylinder and fixed to the inner wall of the separation cylinder. The lifting cavity is arranged between adjacent baffles and the baffles have sliding grooves.

[0028] A movable component, wherein the movable component is slidably connected inside a sliding groove;

[0029] An electric cylinder is fixed inside a sliding groove, and the movable end of the electric cylinder is fixed to a movable component.

[0030] Preferably, the movable component includes:

[0031] A movable plate, which is slidably connected to the inside of a sliding groove, and the drain hole is opened on the movable plate;

[0032] Multiple sliding rods are fixed to one end of a movable plate, and a push plate is sleeved on the surface of the multiple sliding rods. The push plate is fixed to the movable end of the electric cylinder.

[0033] Multiple first springs are disposed between the push plate and the movable plate, and the first springs are sleeved on the outside of the corresponding sliding rods.

[0034] Preferred options also include:

[0035] A pressure sensor is disposed between the first spring and the movable plate. The pressure sensor is used to detect the pressure value of the first spring to determine whether the movable plate has moved to the position of the impurity discharge groove.

[0036] A scraper, which is fixed to the outer wall of the oil drain cylinder;

[0037] After the movable plate moves into the impurity discharge tank, the controller is also used to control the electric cylinder to retract first and then extend after a delay.

[0038] Secondly, the present invention provides a control method for a pretreatment equipment for producing hydrogenated C9 petroleum resin, the control method comprising the following steps:

[0039] The controller acquires a first request information, which is generated by a temperature sensor detecting the temperature inside the separation cylinder.

[0040] The controller generates first control information based on the first request information, and the first control information is used to control the startup of the booster component;

[0041] The controller sends the first control information to the lifting component.

[0042] Preferably, the control method further includes the following steps:

[0043] The controller acquires a second request information, which is generated by the pressure sensor detecting a decrease in the pressure value.

[0044] The controller generates second control information and third control information based on the second request information. The second control information is used to control the electric cylinder to retract, and the third control information is used to control the electric cylinder to extend.

[0045] The controller first sends the second control information to the electric cylinder, and then sends the third control information to the electric cylinder after a delay.

[0046] Compared with the prior art, the present invention has the following beneficial effects:

[0047] 1. Multiple ribs are fixed on the inner wall of the separator. The separator is slowly driven to rotate by the drive mechanism. During the rotation, the ribs stir and mix the raw materials inside the separator to prevent insoluble impurities from settling and accumulating at the bottom, which would affect the separation effect.

[0048] Second, by setting up a lifting component, the lifting component can rotate synchronously with the separation cylinder. When the raw material is first heated, some of the condensed raw material has not yet completely melted. At this time, the lifting chamber of the lifting component is in an open state. As the lifting component rotates with the separation cylinder, the condensed raw material and impurities can leak out from the opening. The lifting component stirs the raw material, further accelerating the melting speed of the condensed raw material. After heating for a period of time, when the raw material has fully melted, the opening of the lifting chamber closes, and the melted raw material flows down from the drain hole, thereby lifting only the impurities to the impurity discharge tank for discharge, further reducing the impact of impurity accumulation on the pretreatment of raw materials.

[0049] Third, by tilting the separation cylinder, impurities can automatically flow to the lifting mechanism under the action of gravity. On the one hand, this can improve the processing effect of the lifting mechanism. On the other hand, the accumulation of impurities at the end of the separation cylinder can also help avoid the situation where impurities accumulate randomly and cause large-area obstruction of the separation screen holes.

[0062] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0063] like Figures 1 to 10 The pretreatment equipment shown includes:

[0064] Reaction vessel 1, which has a reaction chamber 101 inside;

[0065] Separation cylinder 2 is rotatably disposed inside reaction vessel 1. A drive assembly is disposed on the outside of separation cylinder 2 to drive separation cylinder 2 to rotate. Multiple separation sieve holes 201 are opened on the surface of separation cylinder 2. A heating assembly is disposed inside separation cylinder 2.

[0066] Oil drain cylinder 3 is fixed on the surface of reaction tank 1. One end of oil drain cylinder 3 is rotatably connected to separation cylinder 2. An impurity discharge groove 4 is provided between oil drain cylinder 3 and separation cylinder 2. Multiple oil draining holes 301 are opened on the surface of oil drain cylinder 3.

[0067] The separator 2 is tilted, with a feed pipe 5 at the higher end of the separator 2 and an oil draining cylinder 3 at the lower end of the separator 2.

[0068] The lifting assembly is located inside the separation cylinder 2. The lifting assembly has multiple lifting chambers 6, and the bottom surface of the lifting chambers 6 has multiple drainage holes 7.

[0069] When the raw material is not fully melted, the lifting chamber 6 is in an open state, and the condensed raw material and impurities leak out from the opening. When the raw material is fully melted, the lifting chamber 6 switches to a closed state, and the melted raw material flows down from the drain hole 7. The lifting chamber 6 lifts the impurities to the impurity discharge tank 4.

[0070] It should be noted that the heating component is a heating rod 8, which is fixed inside the separation cylinder 2;

[0071] The drive assembly includes a motor 9 and a first gear 10. The motor 9 is fixed on the inner wall of the reaction vessel 1, and the first gear 10 is sleeved and fixed on the outer wall of the separation cylinder 2. A second gear 11 is fixed at the end of the output shaft of the motor 9, and the second gear 11 meshes with the first gear 10.

[0072] An installation plate is fixed to the end of the feed pipe 5, and the installation plate is rotatably connected to the separation cylinder 2;

[0073] In the production process of petroleum resin, the raw materials need to be preheated and melted to separate the impurities that are difficult to melt. Existing technologies mostly use screen separation, but impurities tend to accumulate on the screen surface, affecting the separation effect.

[0074] Specifically, the raw material is added into the separator 2. After the raw material is added, the overall height of the raw material is lower than the height of the impurity discharge tank 4, thereby avoiding the situation where the raw material directly enters the impurity discharge tank 4.

[0075] The reaction vessel 1 is heated by the heating component, so that the raw material in the separation cylinder 2 is heated and melted. The melted raw material flows into the reaction chamber 101 through the separation sieve holes 201 on the surface of the separation cylinder 2.

[0076] Multiple ribs 12 are fixed on the inner wall of the separation cylinder 2. The separation cylinder 2 is slowly driven to rotate by the drive mechanism. During the rotation, the raw materials inside the separation cylinder 2 are stirred and mixed by the ribs 12 to avoid the accumulation of insoluble impurities at the bottom, which would affect the separation effect.

[0077] Furthermore, by setting up a lifting component, the lifting component can rotate synchronously with the separation cylinder 2. When the raw material is just heated, some of the condensed raw material has not yet completely melted. At this time, the lifting chamber 6 of the lifting component is in an open state. During the process of the lifting component rotating with the separation cylinder 2, the condensed raw material and impurities can leak out from the opening position. The lifting component stirs the raw material, which further accelerates the melting speed of the condensed raw material.

[0078] When the raw material is fully melted after heating for a certain period of time, the opening of the lifting chamber 6 is closed, and the molten raw material flows down from the drain hole 7, thereby only lifting the impurities to the position of the impurity discharge tank 4 for discharge, further reducing the impact of impurity accumulation on the pretreatment of raw materials;

[0079] By tilting the separation cylinder 2, impurities can automatically flow to the lifting mechanism under the action of gravity. On the one hand, this can improve the processing effect of the lifting mechanism. On the other hand, the accumulation of impurities at the end of the separation cylinder 2 can also help avoid the situation where impurities accumulate randomly and cause large-area obstruction of the separation screen 201.

[0080] As a further embodiment of the present invention, a control component is also provided inside the reaction vessel 1, the control component including:

[0081] Temperature sensor 13 is fixed inside the separation cylinder 2. Temperature sensor 13 is used to detect the temperature inside the separation cylinder 2 to determine whether the condensed raw material has completely melted.

[0082] Controller 14 is located outside the reaction vessel 1. After the condensed raw material has completely melted, controller 14 is used to control the start of the lifting assembly.

[0083] As a further embodiment of the present invention, the enhancement component includes:

[0084] Equipment cylinder 15 is disposed at the end of separation cylinder 2;

[0085] Baffles 16 are evenly distributed on the surface of the equipment cylinder 15 and fixed on the inner wall of the separation cylinder 2. The lifting cavity 6 is arranged between adjacent baffles 16 and the baffles 16 have sliding grooves 17.

[0086] The movable component is slidably connected inside the sliding groove 17;

[0087] Electric cylinder 18 is fixed inside the sliding groove 17, and the movable end of electric cylinder 18 is fixed to the movable part.

[0088] Specifically, the equipment cylinder 15 is fixed to the separation cylinder 2 under the connection of the baffle plate 16. When the separation cylinder 2 rotates, it can synchronously drive the equipment cylinder 15 and the baffle plate 16 to rotate.

[0089] When the raw material is first added, the moving part retracts inside the sliding groove 17, and an opening is formed between the moving part and the outer wall of the oil drain cylinder 3. During the rotation, even if the impurities and condensed raw materials are lifted to the height of the impurity discharge groove 4, they will leak out from both sides of the baffle plate 16, thereby preventing the condensed raw materials from being discharged into the oil drain cylinder 3.

[0090] Since the inclined cylinder is in an inclined state, after heating one end for a period of time, the raw material is fully melted. The electric cylinder 18 pushes the movable part to move closer to the oil drain cylinder 3, closing the opening. Then, after the impurities are lifted to the height of the impurity discharge tank 4, the impurities can automatically slide into the impurity discharge tank 4.

[0091] As a further embodiment of the present invention, the movable component includes:

[0092] Movable plate 19 is slidably connected to the inside of sliding groove 17, and drain hole 7 is opened on movable plate 19;

[0093] Multiple sliding rods 20 are fixed to one end of the movable plate 19. A push plate 21 is sleeved on the surface of the multiple sliding rods 20. The push plate 21 is fixed to the movable end of the electric cylinder 18.

[0094] Multiple first springs 22 are disposed between the push plate 21 and the movable plate 19, and the first springs 22 are sleeved on the outside of the corresponding sliding rods 20;

[0095] The application scenario of this embodiment is explained as follows: when the movable part moves to the side closer to the oil drain cylinder 3 and closes the opening, it may directly squeeze impurities, causing the movable part to get stuck. If the squeezing is not stopped, the parts of the device will be damaged.

[0096] This implementation method can solve the above problems. The specific working method is as follows: After starting the electric cylinder 18, the electric cylinder 18 pushes the push plate 21 to move. The push plate 21 pushes the first spring 22 and the movable plate 19 to move. When the movable plate 19 squeezes the impurities, the push plate 21 can continue to squeeze the first spring 22, thereby making the first spring 22 shorter and making room to avoid jamming.

[0097] As the movable plate 19 moves, impurities will gradually detach from the end of the movable plate 19. Under the elastic force of the first spring 22, the movable plate 19 can gradually extend, and the end of the movable plate 19 can eventually contact the surface of the oil drain cylinder 3.

[0098] Even if impurities stick to the end of the movable plate 19, when the movable plate 19 moves to the position of the impurity discharge trough 4, since the other side of the impurities is no longer blocked by the outer wall of the oil drain cylinder 3, under the elastic force of the first spring 22, the impurities can be pushed into the position of the impurity discharge trough 4 by the movable plate 19. As the movable plate 19 moves, when the movable plate 19 is about to leave the position of the impurity discharge trough 4, under the blocking effect of the edge of the impurity discharge trough 4, the impurities at the end of the movable plate 19 can also be scraped and cleaned, so that the impurities can fall directly into the interior of the impurity discharge trough 4.

[0099] As a further embodiment of the present invention, it also includes:

[0100] Pressure sensor 23 is disposed between the first spring 22 and the movable plate 19. Pressure sensor 23 is used to detect the pressure value of the first spring 22 to determine whether the movable plate 19 has moved to the position of the impurity discharge groove 4.

[0101] Scraper 24 is fixed to the outer wall of the oil drain cylinder 3;

[0102] After the movable plate 19 moves into the impurity discharge tank 4, the controller 14 is also used to control the electric cylinder 18 to retract first and then extend after a delay.

[0103] Specifically, when the movable plate 19 is squeezed to contact the outer wall of the oil drain cylinder 3, the first spring 22 is in a slightly compressed state. At this time, the pressure sensor 23 detects the pressure value of the first spring 22 and sends the pressure value to the computer terminal.

[0104] When the movable plate 19 moves to the position of the impurity discharge trough 4, the end of the movable plate 19 disengages from the outer wall of the oil drain cylinder 3. At this time, the first spring 22 pushes the movable plate 19 into the interior of the impurity discharge trough 4. The pressure sensor 23 detects that the pressure value of the first spring 22 decreases. When the pressure value decreases to the preset value, the controller 14 controls the electric cylinder 18 to retract, thereby driving the movable plate 19 to retract into the interior of the baffle plate 16.

[0105] Since some raw materials are in a colloidal state after melting, the shielding plate 16 and the movable plate 19 are in an extended state. If they directly enter the raw material solution, the resistance is large. In this embodiment, by making the movable plate 19 retract into the interior of the shielding plate 16 in advance, the overall contact area between the shielding plate 16 and the movable plate 19 and the liquid surface can be reduced, which helps to reduce the difficulty of the shielding plate 16 re-entering the raw material solution.

[0106] Furthermore, when the movable plate 19 retracts, the scraper 24 can prevent some impurities from falling back into the solution as the equipment cylinder 15 rotates.

[0107] Furthermore, by setting a timing system in the computer terminal, after the movable plate 19 retracts into the baffle plate 16 and enters the raw material solution, the electric cylinder 18 is activated after a delay, causing the movable end of the electric cylinder 18 to extend and push the movable plate 19 out again. The specific delay time can be preset according to the working conditions.

[0108] As a further embodiment of the present invention, it also includes:

[0109] Two baffles 25 are fixed on the outer wall of the impurity discharge trough 4.

[0110] Two baffles 25 are set so that after the movable plate 19 moves to the position of the impurity discharge groove 4, it can still maintain part of the pressure of the first spring 22. This helps to delay the retraction time of the electric cylinder 18, so that most of the impurities fall into the impurity discharge groove 4 before the movable plate 19 retracts. This avoids the situation where the impurities lose the support and guidance of the movable plate 19 as soon as they are lifted to the position of the impurity discharge groove 4.

[0111] As a further embodiment of the present invention, it also includes:

[0112] The flexible membrane 26 has its edges fixed to the side wall of the baffle plate 16.

[0113] Mounting groove 27 is formed on the surface of the shielding plate 16 near the flexible membrane 26;

[0114] An extrusion plate 28 is disposed between the flexible membrane 26 and the shielding plate 16. A guide block 29 is fixed at the bottom of the extrusion plate 28. A first inclined surface 30 is provided on one side of the guide block 29. The guide block 29 is slidably disposed inside the mounting groove 27. A second spring 31 is fixed between the extrusion plate 28 and the inner wall of the sliding groove 17.

[0115] Multiple extrusion blocks 32 are fixed on the side wall of the push plate 21. The surface of the extrusion block 32 is provided with a second inclined surface 33, which is adapted to the first inclined surface 30.

[0116] Specifically, when the electric cylinder 18 retracts, pulling the movable plate 19 into the interior of the baffle plate 16, the push plate 21, under the pulling action of the electric cylinder 18, drives the squeezing block 32 to push the guide block 29. Under the guidance of the first inclined surface 30 and the second inclined surface 33, the guide block 29 moves upward and pushes the flexible membrane 26 away from the baffle plate 16, causing the surface of the baffle plate 16 to bulge while the sides are low. On the one hand, this further reduces the difficulty of the baffle plate 16 re-entering the solution. On the other hand, when the lifting chamber 6 is in the open state, the bulging surface of the baffle plate 16 is more conducive to guiding the uncondensed raw materials and impurities to both sides.

[0117] like Figure 11 The method shown is a control method for a pretreatment equipment used in the production of hydrogenated C9 petroleum resin, the control method comprising the following steps:

[0118] The controller 14 acquires the first request information, which is generated by the temperature sensor 13 detecting the temperature inside the separation cylinder 2;

[0119] Controller 14 generates first control information based on the first request information. The first control information is used to control the startup of the booster component.

[0120] The controller 14 sends the first control information to the lifting component.

[0121] As a further embodiment of the present invention, the control method further includes the following steps:

[0122] The controller 14 acquires the second request information, which is generated by the pressure sensor detecting a decrease in pressure value;

[0123] The controller 14 generates second control information and third control information based on the second request information. The second control information is used to control the electric cylinder 18 to retract, and the third control information is used to control the electric cylinder 18 to start extending.

[0124] The controller 14 first sends the second control information to the electric cylinder 18, and then sends the third control information to the electric cylinder 18 after a delay.

[0125] As a further embodiment of the present invention, the specific working method of the temperature sensor 13 includes the following steps:

[0126] Temperature sensor 13 detects the temperature information of the raw material solution;

[0127] Temperature sensor 13 generates first request information based on temperature information;

[0128] Temperature sensor 13 sends the first request information to controller 14;

[0129] When the temperature reaches a preset value, it indicates that the solution has completely melted. The temperature information is then used to generate a first request, which is sent to the controller 14. The controller 14 then generates a first control, which controls the start of the lifting component.
