Specific implementation manners

[0028] To further elaborate on the technical means and effects adopted by the present utility model to achieve the intended utility model purpose, the following will, in conjunction with the accompanying drawings and preferred embodiments, detail the specific implementation manners, structures, features, and their effects of the application according to the present utility model. In the following description, different "one embodiment" or "embodiment" do not necessarily refer to the same embodiment. In addition, the specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0029] As Figure 1 shown, a slag remover for filtering water used in PBT pelletizing proposed in an embodiment of the present utility model includes: a precipitation container main body 1 and a collection pipe 8; the precipitation container main body 1 is a closed cavity structure; the whole of the precipitation container main body 1 is in a rotating body shape; the upper part of the precipitation container main body 1 is a cylindrical cavity; the upper part of the precipitation container main body 1 is a structure where the upper end of a circular pipe is closed and the lower end is open. The lower part of the precipitation container main body 1 is a conical cavity for impurity precipitation; the lower part of the precipitation container main body 1 is fixedly connected to the upper part of the precipitation container main body 1; preferably, it is integrally arranged. The upper part of the precipitation container main body 1 communicates with the lower part of the precipitation container main body 1; one side of the upper part of the precipitation container main body 1 has a water inlet 3 for the entry of water to be filtered; the other side of the upper part of the precipitation container main body 1 has a water outlet 4 for the output of filtered water; preferably, the water inlet 3 and the water outlet 4 are coaxially distributed; the isolation plate 2 is perpendicular to the axes of the water outlet 4 and the water inlet 3 to block the water inlet 3 and the water outlet 4, so that the water at the water inlet 3 must bypass the isolation plate 2 downward to enter the water outlet 4. Utilizing the characteristic that the specific gravity of incomplete PBT particles and powder is higher than that of water, when the water bypasses the isolation plate 2 downward, it promotes the downward deposition of impurities to be discharged through the impurity outlet. The bottom of the precipitation container main body 1 has an impurity outlet; a cleaning valve 7 is provided on the impurity outlet; by opening the cleaning valve 7, the filter medium can be collected into the collection pipe 8.

[0030] An exhaust port 6 is provided at the upper part of the sedimentation container main body 1 for discharging the gas in the sedimentation container main body 1 and controlling the pressure in the sedimentation container main body 1; an exhaust valve is provided on the exhaust port 6 for controlling the exhaust of the exhaust port 6. A partition plate 2 is fixedly provided at the upper part of the sedimentation container main body 1; the partition plate 2 is parallel to the rotation axis of the sedimentation container main body 1; the partition plate 2 is located between the water outlet 4 and the water inlet 3; the partition plate 2 is located on the side close to the water outlet 4 in the sedimentation container main body 1; the partition plate 2 is offset from the rotation axis of the sedimentation container main body 1 towards the water outlet 4 by a predetermined distance; the predetermined distance is 2 / 3 of the upper radius of the sedimentation container main body 1, so that after the water enters through the water inlet 3, it reaches a larger space, reduces the flow rate of the water, and is conducive to the deposition of impurities. Preferably, the partition plate 2 extends downward from the top of the sedimentation container main body 1; the partition plate 2 is hermetically connected to the top and inner wall of the sedimentation container main body 1, so that the medium can only pass through below the partition plate 2.

[0031] Further preferably, the partition plate 2 extends below the water outlet 4; the distance between the lower end of the partition plate 2 and the water outlet 4 is not less than 2 times the diameter of the water outlet 4, so that the medium on the water inlet 3 side can have a larger downward flow distance, which is conducive to the formation of the inertia of the downward flow of impurities. Combined with the own weight of the impurities, it can promote the downward deposition of impurities and improve the deposition effect.

[0032] A purging port 5 is provided at the top of the sedimentation container main body 1; the purging port 5 is used to connect the compressed air delivery pipeline. A purging inlet valve is provided on the purging port 5 for controlling the opening and closing of the purging port 5. The purging inlet valve can be opened in advance during parking or before online cleaning to conduct ventilation and pressurized purging, so as to clean the inside of the sedimentation container main body 1.

[0033] The collection pipeline 8 is horizontally arranged for collecting the filtering medium; a communication port is provided in the middle of the collection pipeline 8; the communication port is communicated with the impurity outlet; a drain valve I 9 is provided at one end of the collection pipeline 8; a drain valve II 10 is provided at the other end of the collection pipeline 8. Open the cleaning valve 7, and the filtering medium is collected into the collection pipeline 8; then close the cleaning valve 7, open the drain valve I 9 and the drain valve II 10, and clean the filtering medium in the collection pipeline 8 to realize the online cleaning of impurities.
