[0026] The ink wastewater is transported to recovery bucket 1, cover plate 4 is covered on the top of recovery bucket 1, recovery bucket 1 is driven to rotate by rotating base 2, and the flocculating agent in feeding tank 5 is added to recovery bucket 1, the ink wastewater in recovery bucket 1 is driven to rotate when recovery bucket 1 rotates, so that the mixing of ink wastewater and flocculating agent is realized, so that ink wastewater and flocculating agent react fully and generate flocculating material, and the flocculating material is collected in the middle of recovery bucket 1 under the action of rotating centrifugal force, so that the collected flocculating material is cleaned by slag cleaning component 6, and the treated harmless ink wastewater is obtained, so that the effect of facilitating harmless treatment of ink wastewater is achieved.

[0027] Refer to Figure 1 And Figure 2 Two telescopic cylinders 31 are arranged on the horizontal section of mounting bracket 3, the piston rod of two telescopic cylinders 31 all extends towards recovery bucket 1, and two telescopic cylinders 31 are opposite with the two sides of cover plate 4 respectively, and cover plate 4 is fixedly installed at the end of two telescopic cylinders 31. Synchronously start two telescopic cylinders 31, the piston rod of telescopic cylinder 31 extends or retracts, so as to drive cover plate 4 to approach or away from recovery bucket 1, so as to facilitate driving cover plate 4 to cover recovery bucket 1.

[0028] Refer to Figure 2 And Figure 3The slag removal assembly 6 comprises a slag removal frame 61, a guide rod 62 and a lifting assembly. The guide rod 62 is vertically arranged on the mounting frame 3 and coaxially arranged with the axis of the recovery bucket 1. The lower end of the guide rod 62 extends into the recovery bucket 1 through the cover plate 4. The slag removal frame 61 is a filter screen frame with an open upper end. The slag removal frame 61 is coaxially arranged on the guide rod 62. The lifting assembly is arranged on the slag removal frame 61 and connected with the guide rod 62. The lifting assembly is used to drive the slag removal frame 61 to move upward along the guide rod 62. When the recovery bucket 1 and the ink wastewater therein rotate, the flocculation in the ink wastewater is collected at the axis of the recovery bucket 1 under the action of centrifugal force. The slag removal frame 61 is driven by the lifting assembly to move upward along the guide rod 62, so that the collected flocculation is cleaned by the slag removal frame 61.

[0029] With reference to Figure 2 and Figure 3 The lifting assembly comprises an electromagnet 71 and a fan blade 72. The slag removal frame 61 is provided with a magnetic metal frame 611. The metal frame 611 is a regular polygon. In this embodiment, the metal frame 611 is a regular octagonal frame. A hinged seat 612 is arranged at each edge of the lower part of the metal frame 611. A rectangular filter screen plate 63 is hingedly arranged on each hinged seat 612 through a rotating shaft. The filter screen plate 63 is also made of magnetic metal. A spring 613 is arranged on the hinged seat 612. The spring 613 is sleeved on the rotating shaft. The spring 613 causes the filter screen plate 63 to always have a tendency to rotate upward to be attached to the metal frame 611. When the plurality of filter screen plates 63 rotate to the vertical state of being attached to the metal frame 611, the adjacent filter screen plates 63 abut against each other. The electromagnet 71 is in the shape of a circular plate. The electromagnet 71 is horizontally arranged at the bottom of the guide rod 62. When the electromagnet 71 is started, the electromagnet 71 generates an attractive force on the metal frame 611 and the filter screen plate 63, so that the plurality of filter screen plates 63 overcome the elastic force of the spring 613 and rotate to the horizontal state. The fan blade 72 is arranged on the side of each filter screen plate 63 away from the metal frame 611. The guide rod 62 is a lead screw. A sleeve is arranged in the metal frame 611 along the axis of the metal frame 611. The sleeve is threadedly sleeved on the lead screw. Further, an insertion slot 711 is formed in the electromagnet 71 corresponding to the plurality of fan blades 72. The insertion slot 711 is used to accommodate the fan blade 72.

[0030] The electromagnetic iron 71 is started, so that the slag removal frame 61 is located at the bottom of the guide rod 62, and the plurality of filter screen plates 63 are in a horizontal state, and the plurality of fan blades 72 are located in the slot 711 on the electromagnetic iron 71. The fan blades 72 are located in the slot 711 and play a role in limiting and fixing the slag removal frame 61, so as to avoid the slag removal frame 61 from moving with the rotation of the ink wastewater. When the ink wastewater in the recovery barrel 1 is completely reacted and the flocculating material has been collected at the position of the central axis of the recovery barrel 1, the electromagnetic iron 71 is turned off. At this time, the plurality of filter screen plates 63 are rotated to the vertical state of being attached to the metal frame 611 under the action of the spring 613. At this time, the rotating ink wastewater drives the slag removal frame 61 to rotate through the fan blades 72. Since the slag removal frame 61 is threadedly sleeved on the guide rod 62 in the shape of a screw rod, the slag removal frame 61 moves upward along the guide rod 62 when rotating, so as to achieve the effect of facilitating the driving of the slag removal frame 61 to move upward along the guide rod 62. The slag removal frame 61 moves upward to clean the flocculating material collected at the central axis of the recovery barrel 1.

[0031] With reference to Figure 1 And Figure 2 A rectangular cross-section clamping rod 621 is connected to the top of the guide rod 62. A rectangular cross-section insertion hole 622 that is adapted to the clamping rod 621 is formed in the mounting rack 3. The clamping rod 621 is inserted into the mounting rack 3 through the insertion hole 622. A latch 623 is further provided on the side surface of the horizontal section of the mounting rack 3 and penetrates the clamping rod 621, so that the guide rod 62 can be detachably mounted on the mounting rack 3. An entrance 41 is formed in the cover plate 4 at the position of the guide rod 62. The entrance 41 is used for the slag removal frame 61 to enter and exit. A baffle 42 is hingedly arranged on the cover plate 4 at the position of the entrance 41. A handle 43 is mounted on the baffle 42 to facilitate the opening and closing of the baffle 42.

[0032] With reference to Figure 1 Further, according to different ink wastewater treatment processes, a plurality of feeding tanks 5 can be arranged on the cover plate 4. Different chemical reagents for treating ink wastewater, such as PH adjusters, coagulants, and decoloring agents, are respectively stored in the plurality of feeding tanks 5.

[0033] The implementation principle of the water-based ink harmless recovery device according to the embodiment of the present application is as follows: the recovery barrel 1 is driven to rotate through the rotating base 2, and the flocculating agent in the feeding tank 5 is added into the recovery barrel 1. The ink wastewater in the recovery barrel 1 is driven to rotate when the recovery barrel 1 rotates, so as to realize the mixing of the ink wastewater and the flocculating agent, make the ink wastewater and the flocculating agent fully react and generate flocculating material, and make the flocculating material collect in the middle part of the recovery barrel 1 under the action of the rotating centrifugal force. At this time, the collected flocculating material is cleaned through the slag removal assembly 6, and the treated ink wastewater is obtained, so as to achieve the effect of facilitating the harmless treatment of the ink wastewater.
