Description

Technical Field

[0001] The utility model relates to the technical field of rosin resin feeding, in particular to a feeding pipe dredging device for rosin resin feeding. Background Art

[0002] During processing, rosin resin needs to be heated in a reactor for reaction, and then the molten rosin resin is discharged. However, since rosin resin is very easy to solidify at low temperatures, it may solidify and block the discharge pipe during the discharge process, so the discharge pipe needs to be unblocked.

[0003] The current method of unclogging the feed pipe is generally to set a heater on the outer side of the feed pipe to heat the feed pipe to prevent the rosin resin in the feed pipe from solidifying. However, this method is difficult to directly conduct heat to the rosin resin in the center of the feed pipe, resulting in a relatively slow temperature rise inside the rosin resin, thereby reducing the feed rate. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a feed pipe dredging device for rosin resin feeding, so as to solve the technical problems mentioned in the above background technology.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions:

[0006] A feed pipe unblocking device for rosin resin feeding comprises a pipe body, wherein the lower half of the pipe body is L-shaped, a side shell is fixedly sleeved on the outer peripheral surface of the pipe body, the side shell is filled with heat transfer oil, a heater is fixedly connected to the outer peripheral side of the side shell, an upper pipe is fixedly penetrated through the upper half of the pipe body, both ends of the upper pipe extend into the side shell, a rotating pipe is arranged within the pipe body, the upper half of the rotating pipe extends into the upper pipe, and the rotating pipe is rotatably connected to the upper pipe, a driving part is arranged below the rotating pipe, and a heat transfer part is arranged inside the rotating pipe.

[0007] By adopting the above technical solution, the first water pump drives the high-temperature heat transfer oil to circulate in the rotating tube and the side shell. The outer peripheral side of the rosin resin in the tube body is heat-conducted by the heat transfer oil in the side shell, and the inside of the rosin resin is heat-conducted by the heat transfer oil in the rotating tube, thereby increasing the heating rate of the rosin resin and further increasing the feeding speed.

[0008] In a preferred embodiment, the present utility model can be further configured as follows: The driving part includes a first water pump fixedly connected to the outer wall of the pipe body. The input end of the first water pump communicates with the side shell. The bottom of the pipe body is fixedly connected with a bottom shell. The lower half of the rotating pipe rotates through the bottom wall of the pipe body and is rotatably connected to the inner bottom wall of the bottom shell. The output end of the first water pump communicates with the bottom shell. An impeller is fixedly sleeved on the outer peripheral surface of the rotating pipe inside the bottom shell. An output pipe is fixedly penetrated through one side of the side shell away from the output end of the first water pump. Part of the output pipe is rotatably connected to the lower half of the rotating pipe.

[0009] By adopting the above technical solution, the first water pump works to drive the heat-conducting oil to circulate inside and outside the pipe body, heating the rosin resin, and driving the rotating pipe to rotate, further improving the heating effect of the rosin resin.

[0010] In a preferred embodiment, the present utility model can be further configured as follows: The heat-conducting part includes a plurality of stirring rods fixedly connected to the outer peripheral surface of the rotating pipe. A heat-conducting channel is formed inside the stirring rod. The heat-conducting channel is formed in a U shape, and both ends of the heat-conducting channel communicate with the inside of the rotating pipe. A drain port is formed on the outer peripheral surface of the rotating pipe inside the upper pipe.

[0011] By adopting the above technical solution, when the rotating pipe rotates, it drives the stirring rods to rotate. The stirring rods heat the rosin resin and drive the rosin resin to be stirred, thereby improving the heating uniformity of the rosin resin, preventing the pipe body from being blocked, and increasing the feeding speed.

[0012] In a preferred embodiment, the present utility model can be further configured as follows: A plurality of partition plates are fixedly connected inside the rotating pipe, and the partition plates are located between both ends of the corresponding heat-conducting channels.

[0013] By adopting the above technical solution, the arrangement of the partition plates hinders the direct vertical movement of the heat-conducting oil inside the rotating pipe, but enables the heat-conducting oil to only move inside the heat-conducting channels, heating the stirring rods, thereby ensuring the temperature rise of the stirring rods and further improving the heating effect inside the rosin resin.

[0014] In a preferred embodiment, the present utility model can be further configured as follows: A second water pump is fixedly connected to the top of the side shell, and the output end of the second water pump extends to the upper half inside the pipe body.

[0015] By adopting the above technical solution, after the feeding is completed, the second water pump drives the cleaning agent to enter the pipe body to clean the inner wall of the pipe body, the stirring rods and the rotating pipe, fully removing the residual rosin resin inside the pipe body and ensuring the smoothness of the pipe body.

[0016] In a preferred embodiment, the present utility model can be further configured as follows: A discharge gate valve is provided at the lower half of the outer peripheral side of the pipe body.

[0017] By adopting the above technical solution, when cleaning the pipe body, the discharge gate valve is closed so that the pipe body is filled with cleaning agent. At this time, the rotating pipe and the stirring rod rotate so that the cleaning agent fully contacts the rosin resin in the pipe body, thereby improving the cleaning effect in the pipe body.

[0018] In summary, the present invention includes at least one of the following beneficial technical effects:

[0019] 1. A rosin resin feeding feed pipe dredging device, wherein the first water pump drives the high-temperature heat transfer oil to circulate inside and outside the pipe body, thereby increasing the internal temperature rise rate of the rosin resin, and drives the stirring rod to rotate to stir the rosin resin, thereby improving the heating uniformity of the rosin resin, preventing the pipe body from being blocked, and thus increasing the feeding speed;

[0020] 2. This is a rosin resin feeding pipe unblocking device. After the feeding is completed, the discharge gate valve is closed, and the second water pump drives the cleaning agent into the pipe body. The pipe body is filled with the cleaning agent. At this time, the rotating tube and the stirring rod rotate to make the cleaning agent fully contact the residual rosin resin in the pipe body. The rosin resin is dissolved in the cleaning agent. The discharge gate valve is opened, and the rosin resin is completely discharged from the pipe body along with the cleaning agent, ensuring the smooth flow of the pipe body.

DETAILED DESCRIPTION

[0026] The utility model is further described in detail below in conjunction with the accompanying drawings. Example

[0027] Reference Figures 1 to 3 The utility model discloses a rosin resin feeding pipe dredging device, comprising a pipe body 1, the lower half of which is L-shaped. A side shell 2 is fixedly sleeved on the outer peripheral surface of the pipe body 1, and the side shell 2 is filled with heat transfer oil. A heater 3 is fixedly connected to the outer peripheral side of the side shell 2.

[0028] An upper tube 4 is fixedly penetrated in the upper half of the tube body 1, and both ends of the upper tube 4 extend into the side shell 2. A rotating tube 5 is arranged in the tube body 1, and the upper half of the rotating tube 5 extends into the upper tube 4, and the rotating tube 5 is rotatably connected to the upper tube 4. A driving part 6 is arranged below the rotating tube 5, and a heat conducting part 7 is arranged in the rotating tube 5.

[0029] In this embodiment, the tube body 1 is made of copper material, which has good heat conduction effect. The side of the side shell 2 close to the tube body 1 is opened, so the heat transfer oil in the side shell 2 can directly contact the tube body 1 and transfer heat to the tube body 1 and the rosin resin in the tube body 1. The heater 3 heats the heat transfer oil in the side shell 2 when working. The upper tube 4 is made of copper material and can also heat the rosin resin.

[0030] In a further preferred embodiment of the present invention, Figure 1 As shown, the driving part 6 includes a first water pump 61 fixedly connected to the outer wall of the tube body 1, and the input end of the first water pump 61 is communicated with the side shell 2. A bottom shell 62 is fixedly connected to the bottom of the tube body 1, and the lower half of the rotating tube 5 rotates through the bottom wall of the tube body 1 and is rotatably connected to the inner bottom wall of the bottom shell 62, and the output end of the first water pump 61 is communicated with the bottom shell 62.

[0031] An impeller 63 is fixedly mounted on the outer circumference of the rotating tube 5 inside the bottom shell 62 , and an output pipe 64 is fixedly penetrated on the side of the side shell 2 away from the output end of the first water pump 61 . The output pipe 64 is partially rotatably connected to the lower half of the rotating tube 5 .

[0032] In this embodiment, the heater 3 works to heat the heat transfer oil. When the first water pump 61 works, it extracts the high-temperature heat transfer oil in the side shell 2 and discharges it into the bottom shell 62. The heat transfer oil impacts the impeller 63 to drive the rotating tube 5 to rotate. The heat transfer oil that passes through the impeller 63 enters the rotating tube 5 through the output pipe 64 and moves upward, so that the rotating tube 5 is heated. The first water pump 61 is a high-temperature resistant pump that can withstand the temperature of the heat transfer oil.

[0033] In a further preferred embodiment of the present invention, Figure 2 and Figure 3 As shown, the heat conducting part 7 includes a plurality of stirring rods 71 ​​fixedly connected to the outer circumference of the rotating tube 5, and a heat conducting channel 72 is provided in the stirring rods 71. The heat conducting channel 72 is provided in a U-shaped shape, and both ends of the heat conducting channel 72 are connected to the inside of the rotating tube 5. A drainage port 73 is provided on the outer circumference of the rotating tube 5 located inside the upper tube 4.

[0034] In this embodiment, the stirring rod 71 is made of copper material. The heat transfer oil moving in the rotating tube 5 enters the heat transfer channel 72, so that the stirring rod 71 is heated. After passing through the heat transfer channel 72, the heat transfer oil continues to move upward along the inside of the rotating tube 5 until it passes through the drain port 73 and enters the upper tube 4, and returns to the side shell 2 through the upper tube 4, thereby realizing the circulation of the heat transfer oil inside and outside the tube body 1 and increasing the heating rate inside the rosin resin.

[0035] When the rotating tube 5 rotates, the heated stirring rod 71 is driven to rotate. The stirring rod 71 stirs the rosin resin while transferring heat with the rosin resin, thereby further improving the heating uniformity of the rosin resin.

[0036] In a further preferred embodiment of the present invention, Figure 3 As shown, a plurality of partitions 8 are fixedly connected inside the rotating tube 5 , and the partitions 8 are located between the two ends of the corresponding heat conducting channels 72 .

[0037] In this embodiment, the partition 8 blocks the movement of the heat transfer oil in the rotating tube 5, so that when the heat transfer oil moves to the bottom of the heat transfer channel 72, it can only pass through the heat transfer channel 72 and then continue to move upward, so that the stirring rod 71 can be fully heated.

[0038] In a further preferred embodiment of the present invention, Figure 1 As shown, a second water pump 9 is fixedly connected to the top of the side shell 2 , and the output end of the second water pump 9 extends to the upper half of the tube body 1 .

[0039] In this embodiment, the input end of the second water pump 9 is connected to the storage box, and the storage box stores a cleaning agent, which can be an organic solvent such as ether and ethanol. After the material is unloaded, the second water pump 9 drives the cleaning agent into the tube body 1 when it works, and the cleaning agent contacts the residual rosin resin in the tube body 1. The rosin resin dissolves in the cleaning agent and is discharged from the tube body 1 along with the cleaning agent, thereby ensuring the smooth flow of the tube body 1.

[0040] In a further preferred embodiment of the present invention, Figure 1 As shown, a discharge gate valve 10 is provided on the lower half of the outer circumference of the tube body 1 .

[0041] In this embodiment, the discharge gate valve 10 controls the opening and closing of the pipe body 1. When discharging, the discharge gate valve 10 is opened. When cleaning the pipe body 1, the discharge gate valve 10 is closed, so that the cleaning agent will remain in the pipe body 1 and immerse the stirring rod 71, the rotating tube 5 and the upper tube 4. At this time, the first water pump 61 works to drive the stirring rod 71 to rotate, so that the cleaning agent can fully contact the rosin resin in the pipe body 1, ensuring that the rosin resin is fully dissolved in the cleaning agent. Then, the discharge gate valve 10 is opened to allow the rosin resin to be completely discharged from the pipe body 1.

[0042] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
