[0003] Patent CN208757998U discloses a high-efficiency epoxy resin powder filtration device, including a filter box. A feed inlet is installed on the top left side of the filter box, and the bottom of the feed inlet is inserted into the inner cavity of the filter box. A discharge outlet is installed on the bottom left side of the filter box, and the top of the discharge outlet is inserted into the inner cavity of the filter box. An opening is provided between the middle and the top of the left side of the filter box. A control panel is installed on the top right side of the filter box, and a power cord is connected to the bottom of the control panel. This invention features hammers connected by springs to the upper left and right sides of the inner cavity of the filter chamber. The two sets of hammers are located on the left and right sides of the filter barrel. When the filter barrel moves horizontally left and right, the hammers strike the filter barrel, effectively preventing epoxy resin powder from adhering to the inner wall of the filter barrel. This avoids the long-term accumulation of epoxy resin powder on the filter barrel, preventing it from malfunctioning and reducing maintenance costs. It is suitable for widespread promotion and use. However, the filtered impurities will accumulate inside the filter barrel. Although the striking mechanism accelerates filtration, the filtered impurities can cause blockage at the bottom of the filter barrel, leading to filtration difficulties. Utility Model Content

[0012] (III) Beneficial Effects

[0013] Compared with the prior art, this utility model provides a foreign matter filtration device for PVC resin powder production, which has the following beneficial effects:

[0014] This foreign matter filtration device for PVC resin powder production features a rotating filter plate that can reciprocate between the filtration and unloading stations. When the plate rotates to the loading station, PVC resin powder to be filtered is poured into the filter plate through the feed hopper. During filtration, the filtered foreign matter is retained at the rounded, curved edges, while the filtered PVC resin powder falls into a hopper below the filtration station. During filtration, a vibration mechanism further agitates the rounded, curved edges to minimize the amount of unfiltered material. The PVC resin powder falls into the hopper below. When the foreign matter inside the curved edge accumulates to a certain amount, the foreign matter filter plate can be rotated downwards to the unloading station, where the foreign matter inside the curved edge can be poured into the hopper at the unloading station. This foreign matter filtration device for PVC resin powder production can continuously and intermittently separate foreign matter multiple times, improving filtration efficiency. Through the inclined setting of the foreign matter filter plate, the PVC resin powder can be filtered quickly, avoiding the situation where the foreign matter filter plate is easily clogged and the filtration is not smooth.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example:

[0023] Please see Figure 1-5 A foreign matter filtration device for PVC resin powder production includes a filter box 1. A foreign matter filter plate 2, which can rotate around one end, is rotatably connected to the upper middle part of the filter box 1. The left and right sides of the filter box 1 are respectively set as a filtration station and a slag discharge station. The free end of the foreign matter filter plate 2 is provided with an arc-shaped curved edge 3 that bends upward when rotated to the filtration station. A feed hopper 9 is fixedly installed on the top of the filter box 1 above the filtration station. A drawer 10 that can be sealed with the filter box 1 is provided at both the filtration station and the slag discharge station.

[0024] Preferably, the filtration station is equipped with a vibration mechanism that can intermittently move the curved edge 3. The vibration mechanism includes a rotating shaft 4 rotatably connected inside the filter box 1 and having multiple paddles 5 fixedly installed circumferentially. A rubber block 6 is fixedly installed on one end of each paddle 5. Furthermore, the included angle between two adjacent paddles 5 in the circumferential direction is set to a minimum of 60 degrees so that the curved edge 3 can rotate through the upper and lower sides of the vibration mechanism. Activating the rubber block 6 facilitates the rotation of the rotating shaft 4, the multiple paddles 5, and the multiple rubber blocks 6. When the paddles 5 rotate, they can drive the curved edge 3 to reciprocate and vibrate. The rubber block 6 reduces wear on the curved edge 3.

[0025] Preferably, it also includes a discharge motor 8 that drives the foreign matter filter plate 2 to rotate. A rotating roller that is rotatably connected to the filter box 1 is fixedly installed on the foreign matter filter plate 2. The output end of the discharge motor 8 is fixedly connected to one end of the rotating roller. When the discharge motor 8 is started, the output shaft of the discharge motor 8 rotates clockwise or counterclockwise by a certain angle, so that the discharge motor 8 can be switched between the two sides of the filter station and the discharge station. When it rotates to the filter station, the arc-shaped curved edge 3 rotates to the top of the vibration mechanism.

[0026] Preferably, the bottom of the feed hopper 9 is provided with a feed port that extends into the filtration station near the slag discharge station, so that the PVC resin powder can flow down from the top of the foreign matter filter plate 2 and be filtered through the foreign matter filter plate 2.

[0027] Preferably, a handle 11 is fixedly installed on the hopper 10 to facilitate pulling the hopper 10 out from the filtration station or the unloading station.

[0028] In use, the foreign matter filter plate 2 can be rotated to the filtration position, and the arc-shaped curved edge 3 can be rotated to the position above the vibration mechanism. Then, PVC resin powder is poured into the feed hopper 9, and the PVC resin powder falls from the top of the foreign matter filter plate 2 downwards for filtration. At the same time, the foreign matter slides down the slope of the foreign matter filter plate 2 to the arc-shaped curved edge 3. Simultaneously, the vibration mechanism is activated to vibrate the arc-shaped curved edge 3, further filtering the PVC resin powder trapped there. When the foreign matter in the arc-shaped curved edge 3 accumulates to a certain amount, the foreign matter filter plate 2 is rotated to the slag discharge position, and the foreign matter in the arc-shaped curved edge 3 falls into the slag discharge hopper 10 at the slag discharge position. After slag discharge, the foreign matter filter plate 2 is rotated to the position above the vibration mechanism, and PVC resin powder is added again through the feed hopper 9. This process is repeated until all the PVC resin powder to be filtered is processed.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
