[0019] In the following, the utility model will be described in detail with reference to the drawings and in combination with the embodiments. It should be noted that, without conflict, the embodiments in the utility model and the features in the embodiments can be combined with each other.

[0020] As Figures 1 to 4 In the embodiment of the diesel pour point depressant filling device of the utility model shown, the diesel pour point depressant filling device includes a storage cylinder 1, a filling head 2 and a conveyor belt 3. The filling head 2 is fixedly connected below the storage cylinder 1. A conveyor belt 3 that can move the packaging bottle up and down is arranged below the filling head 2. The bottom end of the filling head 2 is slidably connected with a filling port 4. A pressing ring 5 is fixedly connected inside the filling port 4. A fixed central rod 6 extends out from the center of the pressing ring 5. The bottom end of the central rod 6 is fixedly connected with a pressing plate 7. The pressing ring 5 abuts against the pressing plate 7. An annular cover 8 for covering the bottle mouth of the packaging bottle is fixedly connected outside the filling port 4.

[0021] Specifically, when the diesel pour point depressant needs to be filled, the pour point depressant in the storage barrel 1 flows to the filling head 2. The conveyor belt 3 conveys the empty packaging bottles to below the filling head 2. The conveyor belt 3 moves upward to push the bottle mouth of the packaging bottle upward to lift the annular cap 8. The filling port 4 is lifted together with the annular cap 8, driving the pressure ring 5 to move upward away from the pressing plate 7. The pour point depressant flows out from the gap between the pressure ring 5 and the pressing plate 7 through the filling port 2 and enters the packaging bottle. During the filling process, the pour point depressant does not come into contact with the air, and the volatile organic compounds contained in the pour point depressant do not enter the air. After filling a certain amount, the conveyor belt 3 descends to separate the bottle mouth from the annular cap 8, and the pressure ring 5 abuts against the pressing plate 7 again, and the filling is completed.

[0022] In an embodiment of the present application, preferably, the central rod 6 is fixedly connected to the top of the filling head 2. A spring 9 is sleeved on the bottom of the filling head 2. The bottom end of the spring 9 abuts against the top end of the filling port 4, so as to always make the annular cap 8 abut against the bottle mouth of the packaging bottle during filling, and reset the filling port 4 when the filling is completed, and the pressure ring 5 abuts against the pressing plate 7 to avoid leakage of the pour point depressant.

[0023] In an embodiment of the present application, preferably, a sealing ring 10 is provided at the bottom end of the filling head 2. The sealing ring 10 contacts the inner wall of the filling port 4. A limiting ring 11 is provided at the top of the filling port 4. When the filling port 4 moves up and down, the connection part between the filling head 2 and the filling port 4 is sealed to avoid leakage of the pour point depressant.

[0024] In an embodiment of the present application, preferably, an exhaust pipe 12 is provided at the centers of the central rod 6 and the pressing plate 7. An exhaust port 13 is provided at the top of the storage barrel 1 for the exhaust of air and volatile gases in the bottle during filling. The exhaust port 13 should be connected to external environmental protection facilities.

[0025] In an embodiment of the present application, preferably, a bottle conveying cavity 14 is provided on the conveyor belt 5. A bottle mouth lifter 15 is provided directly below the filling head 2. A lifting bottle supporting plate 16 is provided directly below the bottle conveying cavity 14 at the bottle mouth lifter 15, so as to support the packaging bottle upward by the bottle supporting plate 16 when the conveyor belt 5 conveys the packaging bottle, so that the bottle mouth of the packaging bottle lifts the annular cap 8.

[0026] In an embodiment of the present application, preferably, the bottom of the conveying cavity 14 is fixedly connected to an equipment box 17. An electric push rod 18 is provided in the equipment box 17. The push rod of the electric push rod 18 is fixedly connected to the bottle supporting plate 16, which is used to lift the bottle supporting plate 16. A weight sensing device for controlling the operation of the electric push rod 18 is also provided on the bottle supporting plate 16 to control the electric push rod 18 to drive the bottle supporting plate 16 and the packaging bottle to lift and lower.

[0027] In an embodiment of the present application, preferably, a feed inlet 19 is provided at the top of the storage barrel 1 for injecting the pour point depressant into the storage barrel 1.

[0028] In summary, for the pourer of diesel fuel flow improver in the above embodiments of the present utility model, specifically, when the diesel fuel flow improver needs to be poured, the flow improver in the storage cylinder 1 flows to the filling head 2. The packaging bottle in the conveying cavity 14 is conveyed to below the filling head 2. The bottle supporting plate 16 pushes the packaging bottle to move upward under the action of the electric push rod 18, so that the bottle mouth of the packaging bottle pushes up the annular cover 8 upward. The filling port 4 is lifted together with the annular cover 8, driving the pressure ring 5 to move upward away from the pressing plate 7. The flow improver flows out from the gap between the pressure ring 5 and the pressing plate 7 through the filling port 4 and enters the packaging bottle. When filling, the air and volatile organic compounds in the bottle are discharged from the exhaust pipe 12 through the exhaust port 13. After filling to the set amount, the electric push rod 18 retracts to drive the bottle supporting plate 16 to descend, so that the bottle mouth is separated from the annular cover 8. Under the action of the spring 9, the filling port 4 returns to its original position, and the pressure ring 5 abuts against the pressing plate 7 again, and the filling is completed. During the filling process, the flow improver does not come into contact with air, and the volatile organic compounds contained in the flow improver will not enter the air, avoiding air pollution and worker injuries.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them. Although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
