[0002] The pour point depressant is a chemical product that can reduce the freezing point of lubricating oil, and its final use is usually in small units, such as a can or a barrel. Because the product has a high viscosity in winter and is in a paste form, a special filling and heating device must be prepared.

[0003] In the existing pour point depressant product for lubricating oil, there is usually no corresponding heating unit during production, which suggests that a heating device should be added to the small unit product at the end of use. SUMMARY

[0004] To overcome the shortcomings of the prior art, the utility model provides a lubricating oil pour point depressant dispersed adding device, which solves the problem of no corresponding heating unit during production of the existing pour point depressant product.

[0008] In one embodiment, the conveying pipe extends through the temperature increasing member to the conveying cylinder, and the inner cavity of the conveying pipe is in communication with the inner cavity of the conveying cylinder;

[0009] The temperature increasing member comprises a sleeve that is sleeved on the conveying cylinder, a plurality of heating bands are mounted on the inner wall of the sleeve in a ring shape and exchange heat with the inner cavity of the conveying cylinder, the sleeve extends synchronously with the conveying cylinder in the extension direction of the conveying cylinder, and the extension length of the sleeve is less than the extension length of the conveying cylinder, and a driving sleeve is mounted on the length difference between the conveying cylinder and the sleeve;

[0010] The mixing and stirring cylinder extends inside the driving sleeve, a gear one is sleeved on the structure of the mixing and stirring cylinder extending inside the driving sleeve, and a gear two that engages with the gear one is mounted on the driving sleeve.

[0011] In one embodiment, the mixing and stirring cylinder comprises a cylinder body and a mixing and stirring rod arranged on the inner wall of the cylinder body, and a plurality of mixing and stirring rods are mounted on the cylinder body in a ring shape at equal distances.

[0012] The insulation component is fitted onto the cylinder and detached from the drive sleeve.

[0013] In one embodiment, the dispersion input end includes an output pipe connected to the inner cavity of the mixing drum and a rubber outer tube sleeved outside the output pipe. The length of the rubber outer tube is less than the length of the output pipe, and a plurality of dispersion ports for dispersing the overflowing pour point depressant into the lubricating oil are opened at the length difference of the output pipe.

Detailed Implementation

[0025] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0026] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] Figures 1-4 This is one embodiment of the present invention. The specific problem addressed in this embodiment is as follows: Pour point depressants are chemicals that lower the freezing point of lubricating oil. Their application is typically in small units, such as a can or a barrel. Because the product has a higher viscosity and a paste-like consistency in winter, specialized filling equipment and processes are required. Most importantly, a heating device is needed to maintain the depressant in a liquid state upon entering the lubricating oil. Currently, existing pour point depressant products for lubricating oil typically lack corresponding heating units during production, leading to the need to add heating equipment to small units of the depressant at the point of use. To address the problems arising from existing products, this solution describes a lubricating oil pour point depressant dispersion and addition device. This device utilizes a heating element 33 and a heat-insulating element 34 installed on the passage from the storage tank 1 to the dispersion input end 4 to increase or maintain the temperature of the pour point depressant. This effectively increases the temperature of the pour point depressant before entering the lubricating oil, maintaining it in a liquid state without crystal precipitation. Simultaneously, after entering the lubricating oil, it exchanges heat with the lubricating oil, further extending the time the lubricating oil remains liquid.

[0028] A specific description is provided for a lubricating oil pour point depressant dispersion and addition device: it includes a storage tank 1 for pre-storing the pour point depressant, with an inlet and a gripping handle 5 installed at the lower end of the inlet. A conveying device 3 for conveying the pour point depressant into the lubricating oil is connected to the lower end of the storage tank 1 via a conveying pipe 2. A shut-off valve is installed on the conveying pipe 2 to control the downward conveying time. The conveying pipe 2 conveys the pour point depressant into the conveying device 3, and the conveying device 3 as a whole conveys the pour point depressant into the lubricating oil. During the conveying process, heating and mixing are performed in the conveying device 3 to increase the temperature of the pour point depressant and maintain a uniform overall temperature of the pour point depressant. The specific conveying device 3 is configured as follows: it includes a conveying cylinder 31 connected to the conveying pipe 2; the conveying pipe 2 extends through the heating element 33 into the conveying cylinder 31 and its inner cavity is connected to the inner cavity of the conveying cylinder 31; one end of the conveying cylinder 31 is rotatably connected to a mixing cylinder 32 for mixing the pour point depressant; both the conveying cylinder 31 and the mixing cylinder 32 are equipped with a shut-off valve, a heating element 33 for increasing and maintaining the temperature of the pour point depressant released from the storage tank 1, and a heat insulation element 34; by wrapping the mixing cylinder 32 with the heat insulation element 34, the heat dissipation of the pour point depressant itself during mixing is reduced; that is, in this scheme, the heat insulation element 34 achieves the heat insulation function; in the production process, it can be a sleeve 331-shaped structure made of heat insulation material, such as heat insulation felt.

[0029] The heating element 33 includes a sleeve 331 fitted onto the conveying cylinder 31. A plurality of heating bands 332 are circumferentially installed on the inner wall of the sleeve 331, exchanging heat with the inner cavity of the conveying cylinder 31. The heat generated by the heating bands 332 is used for heat exchange with the wall of the conveying cylinder 31, and the overall temperature of the pour point depressant is increased by heat transfer generated inside the pour point depressant. The sleeve 331 extends synchronously with the extension direction of the conveying cylinder 31, but its extension length is less than that of the conveying cylinder 31 in the extension direction. A drive sleeve 35 is installed at the length difference between the conveying cylinder 31 and the sleeve 331. A mixing drum 32 extends inside the drive sleeve 35. 32 extends inside the drive sleeve 35. The mixing drum 32 includes a drum body 321 and a mixing rod 322 disposed on the inner wall of the drum body 321. Several mixing rods 322 are installed circumferentially and equidistantly inside the drum body 321. A gear 36 is sleeved on the structure inside the drive sleeve 35 of the drum body 321. A gear 37 that meshes with the gear 36 is installed on the drive sleeve 35. A drive motor is installed on the gear 37 to drive the drum body 321 to rotate, thereby agitating the pour point depressant by the mixing rod 322. The heat insulation component 34 is sleeved on the drum body 321 and is not connected to the drive sleeve 35.

[0030] The end of the cylinder 321 facing away from the drive sleeve 35 is connected to a dispersion input end 4 for adding pour point depressant to the lubricating oil.

[0031] The dispersion input end 4 includes an output pipe 41 connected to the inner cavity of the mixing drum 32 and a rubber outer tube 42 sleeved outside the output pipe 41. The length of the rubber outer tube 42 is less than the length of the output pipe 41, and a plurality of dispersion ports 43 are opened on the length difference of the output pipe 41 for dispersing the pour point depressant into the lubricating oil. This can effectively increase the diffusion area and diffusion efficiency of the pour point depressant in the lubricating oil, increase the effective contact area between it and the lubricating oil, and increase its effect in the lubricating oil.

[0032] The inner wall of the rubber outer tube 42 is attached to the outer wall of the output tube 41 to reduce the damage to the output tube 41 caused by bending. The rubber outer tube 42 is mounted on the cylinder 321 through the mounting seat. A rolling bearing is connected between the mounting seat and the cylinder 321. Based on the movement limit generated by placing the output tube 41 inside the lubricating oil tank opening, the rubber outer tube 42 will not be transferred with the rotation of the cylinder 321 when the cylinder 321 rotates. The output tube 41 extends through the mounting seat into the mixing drum 32 to output the pour point depressant.

[0033] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
