DETAILED DESCRIPTION

[0021] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0022] like Figure 1As shown, the embodiment of the utility model proposes a filtering device suitable for water-based color paste processing, including a filter barrel 1, a recovery pipe 3, a guide plate, a grinding rod 4 and a rotating assembly. A plurality of overflow holes are arranged on the side wall of the filter barrel 1 so that the water-based color paint can be discharged outwardly. The outer wall of the filter barrel 1 is provided with a processing tank, and the processing tank allows the water-based color paint overflowing from the outer wall of the filter barrel 1 to be concentrated and recovered so as to enter the subsequent processing. The length of the recovery pipe 3 is consistent with that of the filter barrel 1 and is arranged vertically. The recovery pipe 3 is arranged inside the filter barrel 1 and is spaced from the inner wall of the filter barrel 1. The bottom of the recovery pipe 3 abuts against the bottom of the filter barrel 1. The rotating assembly is fixedly connected to the recovery pipe 3 so that the recovery pipe 3 rotates around the axis of the filter barrel 1, and the rotating assembly plays a role in limiting the motion trajectory of the recovery pipe 3. The recovery pipe 3 is provided with a feed port 14 from top to bottom on one side close to the inner wall of the filter barrel 1, and there is a gap between the feed port 14 and the bottom of the recovery pipe 3, that is, the gap only appears after the recovery pipe 3 extends upward for a distance. The bottom of the recovery pipe 3 can temporarily store part of the entered paint. The recovery pipe 3 is fixedly provided with a guide plate for allowing the water-based color paste adhering to the side wall and bottom of the filter barrel 1 to enter the recovery pipe 3. The guide plate shovels off the solid impurities or semi-solid paint on the filter barrel 1, and then guides the paint into the recovery pipe 3. The grinding rod 4 is rotatably arranged inside the recovery pipe 3 and is coaxial and adapted with the recovery pipe 3. The grinding rod 4 can move in the vertical direction. In this embodiment, a grinding head 5 is arranged at the bottom of the grinding rod 4, and the grinding head 5 is adapted to the recovery pipe 3. When the grinding head 5 is damaged, it can be replaced. When the impurities on the side wall and bottom of the filter barrel 1 enter the recovery pipe 3, the grinding rod 4 is rotated, and the bottom of the grinding rod 4 and the bottom of the recovery pipe 3 squeeze and grind the impurities, so that the impurities are refined. After the staff lifts the grinding rod 4 upward, the impurities in the recovery pipe 3 are flushed out of the recovery pipe 3 by a water gun, and then filtered out from the filter barrel 1. The staff can spray water downward from the top of the recovery pipe 3, or open a water inlet in the upper section of the recovery pipe 3.

[0023] like Figure 1 , 3As shown, as a preference, the guide plate includes a side shovel plate 6 and a lower shovel plate 7, both of which are made of wear-resistant and corrosion-resistant materials, such as stainless steel and PTFE plastic. The side shovel plate 6 is a vertically arranged long strip plate and has the same depth as the filter barrel 1, so as to shovel away impurities on the upper side wall of the filter barrel 1, one side of the side shovel plate 6 is connected to one side of the feed port 14, and the other side of the side shovel plate 6 abuts against the inner wall of the filter barrel 1, and the side shovel plate 6 and the inner wall of the filter barrel 1 are provided with an inclined angle, so as to shovel away impurities well. The lower shovel plate 7 is arranged at an angle, and the inclined surface corresponds to the side facing forward when the recovery pipe 3 moves, the bottom of the lower shovel plate 7 abuts against the bottom of the filter barrel 1, and the other side edges of the lower shovel plate 7 and the side shovel plate 6 are sealed and connected to the outer wall of the recovery pipe 3. The lower shovel plate 7 allows the bottom impurities between the recovery pipe 3 and the filter barrel 1 to move upward and enter the inside of the recovery pipe 3.

[0024] Preferably, a filter port is provided on the bottom side wall of the recovery pipe 3. When the grinding rod 4 grinds the impurities in the recovery pipe 3, the refined impurities can overflow into the filter barrel 1, and then overflow from the filter barrel 1.

[0025] like Figure 1 , 2 As shown in Figure 3, as a preference, the rotating assembly includes a plurality of sliding grooves 11, a plurality of connecting members 12 and a fixed handle 13. The sliding groove 11 is an annular structure adapted to the inner diameter of the filter barrel 1, and the sliding groove 11 is evenly fixedly arranged in the axial direction of the filter barrel 1. One end of the connecting member 12 is fixedly connected to the recovery pipe 3, and the other end of the connecting member 12 is slidably connected to the sliding groove 11. The fixed handle 13 is fixedly arranged at the upper part of the recovery pipe 3 close to the axis of the filter barrel 1. When the overflow port of the filter barrel 1 is seriously blocked, the staff holds the fixed handle 13 and pushes the recovery pipe 3 to rotate inside the filter barrel 1. When the recovery pipe 3 rotates inside the filter barrel 1, the side shovel plate 6 allows the impurities on the side wall of the filter barrel 1 to be separated. The side shovel plate 6 is provided with a notch corresponding to the sliding groove 11 to prevent the side shovel plate 6 from interfering with the movement of the sliding groove 11 when rotating. In this embodiment, three sliding grooves 11 and three connecting members 12 are provided, and the sliding grooves 11 are respectively arranged at the upper, middle and lower positions of the filter barrel 1. A T-shaped sliding groove 11 is fixedly arranged in the sliding groove 11 , and a T-shaped sliding head is correspondingly arranged at one end of the connecting member 12 , and the two are slidably matched.

[0026] like Figure 1As shown, as a preference, the bottom of the filter barrel 1 is provided with an upwardly protruding conical structure 2, and a gap is provided between the bottom edge of the conical structure 2 and the side wall of the filter barrel 1. When the lower shovel plate 7 moves, the bottom of the lower shovel plate 7 is always above the gap area. When cleaning, the impurities that have separated from the side wall of the filter barrel 1 fall to the bottom of the filter barrel 1 and slide down along the inclined surface of the conical structure 2, so that the lower shovel plate 7 can guide the impurities into the recovery pipe 3. In this embodiment, the bottom of the recovery pipe 3 is always on the inclined surface of the conical structure 2.

[0027] like Figure 1 , 2 As shown, preferably, a top cover 15 is provided on the top of the recovery pipe 3, a through hole is provided in the middle of the top cover 15, and the grinding rod 4 is adapted to the through hole and has clearance fit. When the grinding rod 4 rotates, the top cover 15 supports the grinding rod 4.

[0028] like Figure 4 As shown, as preferably, the rotating assembly also includes a rotating handle 10 fixedly arranged on the top of the grinding rod 4. When there is no motor 8 supply, the staff manually shakes the rotating handle 10, and exerts a downward force to achieve the purpose of grinding.

[0029] Preferably, the rotating assembly further comprises a motor 8 fixedly arranged on the top of the filter barrel 1, and a transmission belt 9 is arranged between the output shaft of the motor 8 and the top of the grinding rod 4. When there are more impurities to be processed, the motor 8 can be used to provide power to grind the impurities. A reducer is arranged in the motor 8. When the motor 8 drives the grinding rod 4 to rotate, the staff holds the fixed handle 13 and then pushes the grinding rod 4 downward, so that the grinding effect can be improved.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
