Description

Technical Field

[0001] The utility model relates to the technical field of separation devices, in particular to a discharge separation device for polyurethane resin. Background Art

[0002] Polyurethane resin is a polymer compound composed of polyurethane monomers. It is usually prepared by reacting isocyanate with polyol, a reaction called polymerization. Polyurethane resin has various forms, which can be liquid, solid or elastomer, and has a wide range of applications. In the processing of polyurethane resin, some impurities or solid particles usually appear, so it is necessary to use a discharge separation device to separate these impurities to maintain the purity and quality of the mixture. Through the discharge separation device, the flow direction and speed of the polyurethane resin mixture can be accurately controlled to meet the production needs of different process requirements and product specifications.

[0003] The separation structure of a traditional discharging and separation device is usually composed of a separation plate and a filter screen. When the polyurethane resin is placed in the device during use, the screen and filter assembly need to be driven by a motor to filter and separate it. The filtered polyurethane resin is sent out of the device, and the impurities filtered out are manually processed to completely separate the polyurethane resin from the impurities.

[0004] However, since the traditional discharge separation device has a relatively simple structure and usually has only one discharge port, it is not possible to distinguish the separated impurities and polyurethane resin. Therefore, after the separation is completed, the impurities and polyurethane resin cannot be discharged from the device together, and additional processes and manpower are required to clean up the impurities, which increases the production cost and workload. In addition, the position of the separation plate cannot be adjusted during the separation process, and the separation effect cannot be controlled as needed, which reduces the processing efficiency. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a discharging and separation device for polyurethane resin, comprising a fixed frame, a material barrel is fixedly connected inside the fixed frame, a separation tube is fixedly connected to the bottom of the material barrel, a fixed frame is fixedly connected to one side of the separation tube, a rotating block is rotatably connected inside the fixed frame, an electric push rod is fixedly connected to the bottom of the rotating block, a connecting frame is fixedly connected to the output end of the electric push rod, a sliding column is fixedly connected inside the connecting frame, a rotating column is rotatably connected inside the separation tube, a rotating rod is rotatably connected to the outer wall of the rotating column, the rotating rod is rotatably connected to one side of the separation tube, a sliding groove is provided inside the rotating rod, the outer wall of the sliding column is slidably connected to the inside of the sliding groove, and a separation component is provided on the outer wall of the rotating column.

[0007] Furthermore, the separation component includes a filter screen, the bottom of which is fixedly connected to the outer wall of the rotating column, and the top of which is in contact with the inner wall of the separation tube.

[0008] Furthermore, a feed pipe is fixedly connected to the top of the barrel, and a base is fixedly connected to the top of the barrel.

[0009] Furthermore, a turntable is rotatably connected to the top of the base, and a handle is fixedly connected to the top of the turntable.

[0010] Furthermore, a connecting block is fixedly connected to the outer wall of the turntable, and a first connecting rod is rotatably connected to the top of the connecting block.

[0011] Furthermore, one side of the first connecting rod is rotatably connected to the second connecting rod, and one side of the second connecting rod is rotatably connected to the L-shaped rod.

[0012] Furthermore, a support rod is rotatably connected to the top of the base, and an opening and closing cover is slidably connected to the top of the feed pipe.

[0013] Furthermore, the L-shaped rod and one side of the support rod are both rotatably connected to one side of the opening and closing cover.

[0014] The utility model has the following beneficial effects:

[0015] 1.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1-Figure 3The utility model provides an embodiment of a polyurethane resin discharging and separating device, comprising a fixed frame 1, a material barrel 2 is fixedly connected inside the fixed frame 1, a separation tube 3 is fixedly connected to the bottom of the material barrel 2, a fixed frame 4 is fixedly connected to one side of the separation tube 3, a rotating block 5 is rotatably connected inside the fixed frame 4, an electric push rod 6 is fixedly connected to the bottom of the rotating block 5, a connecting frame 7 is fixedly connected to the output end of the electric push rod 6, a sliding column 8 is fixedly connected inside the connecting frame 7, a rotating column 11 is rotatably connected inside the separation tube 3, a rotating rod 9 is rotatably connected to the outer wall of the rotating column 11, the rotating rod 9 is rotatably connected to one side of the separation tube 3, a sliding groove 10 is opened inside the rotating rod 9, the outer wall of the sliding column 8 is slidably connected inside the sliding groove 10, a separation component is arranged on the outer wall of the rotating column 11, and the separation component comprises a filter screen 12, the bottom of the filter screen 12 is fixedly connected to the outer wall of the rotating column 11, and the top of the filter screen 12 contacts with the inner wall of the separation tube 3.

[0025] Specifically, when using the discharge separation device, if the position of the filter screen 12 needs to be adjusted, the connection frame 7 is first driven to move by the output end of the electric push rod 6. After the connection frame 7 is subjected to force, the internal fixedly connected sliding column 8 slides in the slide groove 10, and at the same time drives the rotating rod 9 to rotate. After the rotating rod 9 is subjected to force, the internally rotatably connected rotating column 11 rotates in the separation tube 3, thereby driving the filter screen 12 fixedly connected to the outer wall to rotate. In this way, the filter screen 12 can be blocked at a certain outlet in the separation tube 3 to achieve separation and filtration of the resin. The impurities can fall into another discharge port in the separation tube 3 through the action of the filter screen 12, thereby achieving the simultaneous discharge of the resin and the impurities.

[0026] Reference Figure 1 and Figure 4 A feed pipe 13 is fixedly connected to the top of the barrel 2, a base 14 is fixedly connected to the top of the barrel 2, a turntable 15 is rotatably connected to the top of the base 14, a handle 16 is fixedly connected to the top of the turntable 15, a connecting block 17 is fixedly connected to the outer wall of the turntable 15, and a first connecting rod 18 is rotatably connected to the top of the connecting block 17.

[0027] Specifically, when feeding, the operator turns the handle 16 to apply force to the turntable 15 fixedly connected at the bottom, so that the turntable 15 rotates on the top of the base 14. As the turntable 15 rotates, the connecting block 17 fixedly connected to the outer wall is driven to rotate. The movement of the connecting block 17 is further transmitted to the first connecting rod 18 at the top, causing it to start rotating, thereby achieving a driving effect.

[0028] Reference Figure 1 and Figure 4One side of the first connecting rod 18 is rotatably connected to the second connecting rod 19, one side of the second connecting rod 19 is rotatably connected to the L-shaped rod 20, the top of the base 14 is rotatably connected to the support rod 21, the top of the feed pipe 13 is slidably connected to the opening and closing cover 22, and one side of the L-shaped rod 20 and the support rod 21 are both rotatably connected to one side of the opening and closing cover 22.

[0029] Specifically, the movement of the first connecting rod 18 drives the second connecting rod 19 connected to one side to start rotating, and then acts on the L-shaped rod 20 connected to one side. The force applied to the L-shaped rod 20 causes the opening and closing cover 22 connected to one side to slide on the top of the feed pipe 13. At the same time, the movement of the opening and closing cover 22 drives the support rod 21 connected to one side to rotate. This complex action chain ultimately enables the opening and closing cover 22 of the feed port to open outward quickly, realizing the rapid opening and closing of the feed port.

[0030] Working principle: when the position of the filter 12 needs to be adjusted during the process of using the discharge separation device, the connection frame 7 is first driven to move by the output end of the electric push rod 6. The connection frame 7 is forced to drive the internal fixed sliding column 8 to slide inside the slide groove 10, and the sliding column 8 drives the rotating rod 9 to rotate. The rotating rod 9 is forced to drive the internal rotating column 11 to rotate inside the separation tube 3. At the same time, the rotating column 11 is forced to drive the filter 12 fixed to the outer wall to rotate, so that the filter 12 blocks one of the outlets opened inside the separation tube 3, and the resin is separated and filtered. Through the action of the filter 12, the separated impurities fall into another discharge port opened inside the separation tube 3, thereby achieving the effect that the resin and impurities can be sent out at the same time. When feeding, by rotating the handle 16, the handle 16 is forced to drive the turntable 15 fixed at the bottom to rotate on the top of the base 14, the turntable 15 is forced to drive the connecting block 17 fixed to the outer wall to rotate, the connecting block 17 is forced to drive the first connecting rod 18 connected to the top rotationally to rotate, the first connecting rod 18 is forced to drive the second connecting rod 19 connected to one side rotationally to rotate, the second connecting rod 19 is forced to drive the L-shaped rod 20 connected to one side rotationally to rotate, the L-shaped rod 20 is forced to drive the opening and closing cover 22 connected to one side to slide on the top of the feeding pipe 13, and at the same time, the opening and closing cover 22 is forced to drive the support rod 21 connected to one side rotationally to rotate, so that the opening and closing cover 22 is opened outward, thereby achieving the effect of quickly opening and closing the feeding port.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
