Description

Technical Field

[0001] The present application belongs to the technical field of printing equipment, and in particular relates to an ink recovery device for a three-roller grinder. Background Art

[0002] Printing equipment: machinery that processes and finishes printed sheets into finished printed products. There are three methods of book binding: thread binding, paperback and hardcover. Generally, it goes through the processes of cutting, folding, collating (matching), book core processing, stapling, cover wrapping, book cutting and packaging. Three-roller grinders are widely used in printing equipment.

[0003] During the printing process of the three-roller grinder, a large amount of ink is consumed, so a large amount of ink wastewater is generated. The wastewater contains a large amount of ink particles and pigments. If it is discharged directly, it will not only pollute the environment, but also cause waste of ink. At present, the commonly used ink wastewater treatment methods include precipitation, filtration, adsorption, etc., but these methods have problems such as low treatment efficiency, poor recovery effect and high cost.

[0004] Therefore, we propose a three-roller grinding machine ink recovery device to solve the above problems. Utility Model Content

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A three-roller grinding machine ink recovery device comprises a base, the upper surface of the base is respectively fixedly connected with a centrifuge, a controller and a filter box, the interior of the filter box is respectively slidably connected with a first filter screen and a second filter screen, a water pump is arranged above the base, the input end of the water pump is fixedly connected with the left side surface of the filter box, the output end of the water pump is fixedly connected with a transport pipe, the end of the transport pipe away from the water pump is fixedly connected with the upper surface of the centrifuge, the inner wall of the filter box is fixedly connected with a stabilizing plate, and the bottom surface of the stabilizing plate is fixedly connected with an ultrasonic sensor.

[0008] Preferably, a sealing plug is fixedly connected to the upper surface of the filter box, and an injection pipe is threadedly connected to the inner wall of the sealing plug.

[0009] Preferably, the outer surface of the transport tube is sleeved with a collar, and the bottom end of the collar is fixedly connected to the upper surface of the centrifuge.

[0010] Preferably, a fixing frame is fixedly connected to the outer surface of the controller, and the bottom surface of the fixing frame is fixedly connected to the upper surface of the base.

[0014] In summary, the technical effects and advantages of this application are:

[0015] By setting up a controller, a water pump, a transport pipe, a filter box, a centrifuge, a first filter screen, a second filter screen, an ultrasonic sensor and a stabilizing plate, the ink can be fully filtered and separated, which is beneficial to fully separate the impurity particles in the ink, and the ink wastewater is discharged into the interior of the filter box, and then filtered through the first filter screen and the second filter screen. The filtered ink wastewater enters the bottom of the filter box, and the ultrasonic sensor is used to monitor the water level of the ink wastewater at the bottom of the filter box. The ultrasonic sensor measures the water level by sending a sound wave beam. When the beam is emitted from the sensor, It will reflect on the ink surface and then reflect back to the sensor. The time from transmission to reception changes with the change of water level, so the ink water level height can be measured. When the height of the ink wastewater exceeds or approaches the value set by the controller, the controller will issue an early warning and control the water pump to work to pump the ink wastewater in the filter box into the centrifuge through the transport pipe. The centrifuge is then used to work. Under the action of centrifugal force, the centrifuge performs secondary filtration on the ink wastewater to fully separate the impurities in the ink wastewater from the water, and then the ink impurities are recovered to prevent the impurities from being discharged into the environment and causing pollution to the environment.

[0023] The interior of the filter box 8 is slidably connected with a first filter screen 14 and a second filter screen 15, and two pull rings 2 are arranged on the outside of the filter box 8. The front of the first filter screen 14 and the front of the second filter screen 15 are fixedly connected to the back of the pull ring 2. The pull ring 2 is used to facilitate the staff to take and store the first filter screen 14 and the second filter screen 15, thereby further improving the working efficiency of the device.

[0024] A water pump 11 is arranged above the base 1, and a fixing plate 12 is fixedly connected to the outer surface of the water pump 11. The bottom surface of the fixing plate 12 is fixedly connected to the upper surface of the base 1. The fixing plate 12 can be used to fix the water pump 11 to avoid the problem of shaking of the water pump 11 during use.

[0025] The input end of the water pump 11 is fixedly connected to the left side of the filter box 8, and the outer surface of the water pump 11 is fixedly connected with a fixing ring 13. The outer surface of the fixing ring 13 is fixedly connected to the left side of the filter box 8. The fixing ring 13 can be used to reinforce the outer surface of the water pump 11 to prevent the water pump 11 from being in a stable state during use.

[0026] The output end of the water pump 11 is fixedly connected to the transport pipe 7, and the end of the transport pipe 7 away from the water pump 11 is fixedly connected to the upper surface of the centrifuge 5. The inner wall of the filter box 8 is fixedly connected to the stabilizing plate 16, and the bottom surface of the stabilizing plate 16 is fixedly connected to the ultrasonic sensor 17. The upper surface of the filter box 8 is fixedly connected to the sealing plug 9, and the inner wall of the sealing plug 9 is threadedly connected to the injection pipe 10.

[0028] The working principle of the utility model is as follows: when in use, the controller 4, the ultrasonic sensor 17, the centrifuge 5 and the water pump 11 are first connected to the power supply. When the device is used to recycle ink wastewater, the staff injects the ink wastewater into the interior of the filter box 8 through the injection pipe 10, and then the ink wastewater is initially filtered through the first filter screen 14 and the second filter screen 15 in turn to filter out large impurity particles. After that, the ink wastewater enters the bottom of the filter box 8, and then the staff uses the controller 4 to control the ultrasonic sensor 17 to work. The ultrasonic sensor 17 measures the water level by sending a sound wave beam. When the beam is emitted from the sensor, it will be reflected on the ink surface. , and then reflected back to the sensor. The time from transmission to reception changes with the change of water level, so the height of the ink wastewater water level can be measured. When the ink wastewater water level value inside the filter box 8 is compared with the rated value set by the controller 4, when the ink wastewater exceeds the set value, the controller 4 controls the pump 11 to work, and the pump 11 extracts the ink wastewater inside the filter box 8 and transports it to the inside of the centrifuge 5 through the transport pipe 7. Then, the centrifugal force of the centrifuge 5 is used to separate the impurities in the ink wastewater for the second time, further improving the effect of filtering, separating and recovering the ink wastewater. Then, the separated ink impurities are recovered to avoid impurities being discharged into the environment and polluting the environment.
