Description

Technical Field

[0001] This utility model relates to the field of pour point depressant production technology, and in particular to a production apparatus for a feedstock oil pour point depressant. Background Technology

[0002] Pour point depressants are chemicals that can lower the pour point of lubricating oil. They are generally high-molecular-weight organic compounds. Many varieties are the same as those used in oil and gas extraction. Commonly used varieties in lubricating oils include alkyl naphthalene, polymethyl methacrylate, and poly-α-olefin. Among them, poly-α-olefin (code T803) is a new type of light-colored pour point depressant developed in the 1970s. It uses soft wax cracked olefins as raw materials, which are appropriately refined and then polymerized in the presence of Ziegler-Natta catalyst. The molecular weight is adjusted with H2, and the catalyst is removed by washing with esterified water in the post-treatment.

[0003] According to Chinese Patent Publication No. CN222805010U, a production device for pour point depressant used in high-pour-point feedstock oil is proposed. The output of a first motor drives a turntable to rotate. Under the action of the guide rail, the turntable rotates and moves the interference plate. Under the action of the interference plate, the accumulated pour point depressant is leveled, thereby improving the production efficiency of the pour point depressant, avoiding equipment blockage or uneven production of pour point depressant, and improving product quality. By increasing the evaporation area of ​​water under the action of the water curtain plate, the water evaporation removes the heat inside the pour point depressant production tank. Under the action of the fan, the cooler air inside the pour point depressant production tank is blown out through the filter plate, thereby cooling the pour point depressant on the automatic conveyor belt and improving the working efficiency of the pour point depressant production device.

[0004] In this application, although the accumulated pour point depressant is leveled before cooling, the pour point depressant and the automatic conveyor belt are in a relatively static state when the pour point depressant enters the pour point depressant production tank for cooling, while the cold air is blown out from above the pour point depressant. This may result in inconsistent cooling efficiency in different parts of the pour point depressant, leading to problems such as unstable product quality. Therefore, a production device for feedstock oil pour point depressant is proposed to solve the above problems. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] like Figure 1-5As shown, the present invention proposes a production device for a raw material oil pour point depressant, comprising an installation plate 1, two vertical plates 2 mounted on the top of the two installation plates 1, a conveyor belt mounted between opposite sides of the two vertical plates 2, a fixing plate 3 mounted on the top of each of the two vertical plates 2, a pour point depressant production box 4 mounted on the top of the two fixing plates 3, a cooling mechanism being provided inside the pour point depressant production box 4, an inclined guide plate 6 corresponding to the left side of the conveyor belt being mounted on the top of the installation plate 1, and a toggle mechanism 5 being provided on the left side of the pour point depressant production box 4.

[0027] In this invention, the pour point depressant can be transported via a transmission belt, and the pour point depressant can be cooled via the pour point depressant production tank 4 and the cooling mechanism. During the cooling process, the pour point depressant can be moved by the agitator 5, causing the pour point depressant to roll or shift at the top of the conveyor belt, thereby making the cooling of the pour point depressant more uniform and thorough.

[0028] The cooling mechanism includes a water tank installed on one side of the inner cavity of the pour point depressant production tank 4. A water inlet is connected to the top wall of the water tank, and water holes are opened on the bottom side of the inner wall. Two water curtain plates are rigidly connected to the inner wall of the pour point depressant production tank 4. A water receiving trough is opened on one side of the inner wall of the pour point depressant production tank 4, and a water pump is installed on one side of the inner wall of the water receiving trough. A water delivery pipe is installed on one side of the surface wall of the water pump. A wind box is rigidly connected to one side of the surface wall of the pour point depressant production tank 4, and a fan is installed on one side of the inner wall of the wind box. A filter plate is rigidly connected to the bottom side of the inner wall of the pour point depressant production tank 4. By increasing the evaporation area of ​​the water under the action of the water curtain plates, the evaporation of water carries away the heat inside the pour point depressant production tank 4. Under the action of the fan, cooler air inside the pour point depressant production tank 4 is blown out through the filter plate, thereby cooling the pour point depressant on the automatic conveyor belt during the pour point depressant production process.

[0029] like Figure 2-3 As shown, in an optional embodiment, the actuating mechanism 5 includes a horizontal plate 51 fixedly installed on the left side of the pour point depressant production box 4. A fixed box 52 is fixedly installed at the bottom of the horizontal plate 51. A displacement plate 53 is provided on the right side of the fixed box 52. A drive assembly 54 for moving the displacement plate 53 is provided inside the fixed box 52. The fixed box 52 is connected to the displacement plate 53 through the drive assembly 54. A support assembly 55 for supporting the displacement plate 53 is provided between the opposite sides of the two vertical plates 2. L-shaped plates 56 are fixedly installed on both the front and back of the displacement plate 53. Mounting rods 57 are fixedly installed at the bottom of the two L-shaped plates 56. Multiple evenly distributed actuating rods 58 are fixedly installed at the bottom of the two mounting rods 57. The bottom of the actuating rods 58 is in contact with the top of the conveyor belt.

[0030] The fixed box 52 can be installed via the horizontal plate 51, and the displacement plate 53 can be driven to move back and forth via the drive assembly 54. The displacement plate 53 will drive the two L-shaped plates 56 to move back and forth, and the L-shaped plates 56 will drive the mounting rod 57 to move back and forth. The mounting rod 57 will drive multiple toggle rods 58 to move back and forth. These multiple toggle rods can move the pour point depressant on the top of the conveyor belt, causing the pour point depressant to roll or move, thereby ensuring that the pour point depressant is cooled more evenly and fully. The support assembly 55 can support the displacement plate 53 to ensure the stability of the displacement plate 53 during movement.

[0032] When the drive motor 541 is started, the output shaft of the drive motor 541 will drive the rotating disk 542 to rotate. The rotating disk 542 will drive the fixed rod 545 to rotate. During the rotation, the fixed rod 545 will press against the side wall of the through hole 544. Under the action of the through hole 544, the fixed rod 545 will drive the movable rod 543 to move back and forth. The movable rod 543 will drive the displacement plate 53 to move back and forth.

[0033] The bottom of the movable rod 543 is slidably connected to the inner bottom wall of the fixed box 52. Under the action of the T-shaped module 546, the stability of the movement of the T-shaped module 546 can be ensured. At the same time, a sliding hole is provided on the right side of the fixed box 52, which extends into its interior. The displacement plate 53 is slidably connected to the inside of the sliding hole. The displacement plate 53 can be limited through the sliding hole to ensure the stability of the movement of the displacement plate 53.

[0034] like Figure 4 As shown, in an optional embodiment, the T-shaped module 546 includes a T-shaped groove 5461 formed in the left side wall of the inner cavity of the fixed box 52, and a T-shaped block 5462 is fixedly installed on the left side of the movable rod 543, and the T-shaped block 5462 is slidably connected to the inside of the T-shaped groove 5461.

[0035] The T-block 5462 and T-slot 5461 can limit and guide the movable rod 543, ensuring the stability of the movement of the movable rod 543 while preventing the fixed rod 545 from separating from the through hole 544.

[0036] like Figure 2 As shown, in an optional embodiment, the support assembly 55 includes a support rod 551 fixedly installed between two fixed plates 3 on opposite sides. The support rod 551 has a support groove 552 on its left side. The right end of the displacement plate 53 extends into the support groove 552 and is slidably connected to the inside of the support groove 552.

[0037] The right side of the displacement plate 53 can be supported by the support rod 551 and the support groove 552 to ensure the stability of the displacement plate 53 during movement and prevent the displacement plate 53 from shifting.

[0038] like Figure 5 As shown, in an optional embodiment, a base plate 7 is provided below the mounting plate 1, and four vertical rods 8 are fixedly installed on the top of the base plate 7. The tops of the four vertical rods 8 are respectively fixedly connected to the four bottom corners of the mounting plate 1, and a cleaning mechanism 9 is provided on the top of the base plate 7.

[0039] The mounting plate 1 can be installed and supported by the base plate 7 and four vertical rods 8. During the process of conveying the pour point depressant, some pour point depressant may stick to the outside of the conveyor belt. The cleaning mechanism 9 can clean the surface of the conveyor belt to ensure its cleanliness.

[0040] like Figure 5 As shown, in an optional embodiment, the cleaning mechanism 9 includes a cleaning plate 91 fixedly installed at the bottom of two vertical plates 2. A cleaning motor 92 is installed on the back of the back vertical plate 2. A rotating roller is connected to the output shaft of the cleaning motor 92 via a coupling. The front of the rotating roller is rotatably connected to the back of the front cleaning plate 91. A brush 93 is detachably connected to the outside of the rotating roller. The outside of the brush 93 contacts the bottom of the conveyor belt. A collection frame 94 is placed on the top of the bottom plate 7. The collection frame 94 corresponds to the rotating roller.

[0041] When conveying the pour point depressant, the cleaning motor 92 is started. The output shaft of the cleaning motor 92 drives the rotating roller to rotate, which in turn drives the outer brush 93 to rotate. The rotation direction of the brush 93 is opposite to the movement direction of the bottom of the conveyor belt, so that the brush 93 cleans the surface of the conveyor belt during operation. The cleaned residue falls directly into the collection box 94, which is convenient for collecting, processing or recycling these residues.

[0042] Both the inner side of the brush 93 and the outer side of the rotating roller are equipped with Velcro straps that can be used to replace the brush 93.

[0043] like Figure 1 As shown, a controller is installed on the outside of the pour point depressant production tank 4. The conveyor belt, drive motor 541, water pump, fan and cleaning motor 92 are all electrically connected to the controller. The controller can control the conveyor belt, drive motor 541, water pump, fan and cleaning motor 92.

[0044] Working principle:

[0045] The production device for the raw material oil pour point depressant, when in use, involves starting the conveyor belt, drive motor 541, water pump, fan, and cleaning motor 92. The pour point depressant is transported via the conveyor belt. When the pour point depressant is transported into the pour point depressant production tank 4, it is cooled by the cooling mechanism. Simultaneously, the drive motor 541 drives the displacement plate 53 to move back and forth through transmission. The displacement plate 53 drives two L-shaped plates 56 to move back and forth, which in turn drives the mounting rod 57 to move back and forth. The mounting rod 57 then drives multiple actuating rods 58 to move back and forth. These actuating rods actuate the pour point depressant at the top of the conveyor belt, causing it to tumble or move, thus ensuring more uniform and thorough cooling. The cooled pour point depressant is then discharged through the inclined guide plate 6.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
