[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 , Figure 2 and Figure 4The utility model provides a waste ink barrel drying device, comprising a box body 100, a smoke heat-blocking plate 200 and a smoke collecting hood 300. The box body 100 is provided with a drying barrel chamber 110 and a heating chamber 120 located below the drying barrel chamber 110. The heating chamber 120 is provided with an air intake window and an electric heating tube 121. The air intake window is encapsulated with an air intake heat-blocking plate 122. The drying barrel chamber 110 and the heating chamber 120 are separated by a metal mesh plate 130, so that the heating chamber 120 forms a space for uniform heat overflow. The front wall and the top of the drying barrel chamber 110 are respectively provided with an operation window 111 and a smoke exhaust window 112. The operation window 111 is suitable for storing and accessing the waste ink barrel 600 and is connected with a door panel. The smoke heat-blocking plate 200 is suitable for covering the smoke exhaust window 112. The smoke collecting hood 300 is suitable for covering the smoke heat-blocking plate 200 and is provided with a smoke exhaust fan 310.

[0032] Reference Figure 1 , Figure 2 The operating window 111 of the box 100 can be provided with a hinged door panel or a sliding door panel; the door panel is provided with a certain sealing strip / sealing ring.

[0033] The peripheral wall of the box body 100 may be a double-layered cavity wall, and the outer wall of the box body 100 may also be provided with a heat-insulating layer, such as a heat-resistant foam board or a honeycomb board. Preferably, the drying barrel chamber 110 is provided with a thermometer.

[0034] The waste ink barrel 600 is suitable for standing upright in the drying barrel chamber 110, with its opening facing upward, so that the oil smoke and water vapor can directly overflow to the fume hood 300. Preferably, the fume hood 300 is connected to an oil fume treatment device, such as a spray tower, a reagent solution tank, a combustion tower, etc.

[0035] When the barrel is initially dried, the electric heating tube 121 works at the heating power (i.e., the voltage of the electric heating tube 121 when heating is set to U1 / heating current A1); when the temperature of the barrel chamber 110 is fed back by the thermometer as T±5°C, the electric heating tube 121 works at the insulation power (i.e., the voltage of the electric heating tube 121 when insulation is set to U2 / heating current A2, so that the heating and heat dissipation of the barrel chamber 110 are close to equilibrium). Among them, T=about 100°C to 180°C, and the T value is selected according to the curing characteristics of different inks. It can be understood that the working voltage / current of the electric heating tube 121 can be adjusted by a sliding rheostat; better, it also includes a controller such as a PLC, a single-chip microcomputer, and the heating and insulation working temperatures of the electric heating tube 121 are automatically adjusted by the controller.

[0036] To reduce heat loss and make full use of heat, the smoke exhaust fan 310 is suitable for low speed rotation during operation, such as 0.3 to 2 revolutions per second (0.3 to 2 r / s); when the operating window 111 needs to be opened, the smoke exhaust fan 310 is adjusted to high speed rotation, such as a speed ≥ 5 r / s.

[0037] As for the air intake heat-resisting plate 122, the metal mesh plate 130 and the smoke outlet heat-resisting plate 200, it can be understood that the pores of the air intake heat-resisting plate 122 and the smoke outlet heat-resisting plate 200 are smaller than those of the metal mesh plate 130, and the heat-resisting effect of the air intake heat-resisting plate 122 and the smoke outlet heat-resisting plate 200 is to minimize heat loss, not to completely block heat. The metal mesh plate 130 is mainly suitable for cooperating with the air intake heat-resisting plate 122 to form a new air equalizing chamber in the heating chamber 120 that is conducive to temporarily suspending the fresh air, allowing the fresh air to fully dissipate to be fully heated (i.e., homogenized), and then homogenized to overflow upward.

[0038] Reference Figure 2 On the other hand, the pores of the metal mesh plate 130 are larger than those of the air inlet heat-resisting plate 122 and the smoke outlet heat-resisting plate 200, but the metal mesh plate 130 itself is a metal sheet with good thermal conductivity, so that the metal mesh plate 130 presents a uniformly heated plane body, and the metal mesh plate 130 evenly distributes heat upward; under the "hatching" effect of the metal mesh plate 130, the airflow passing through the metal mesh plate 130 is more uniformly heated.

[0039] The air inlet heat-blocking plate 122 and the smoke outlet heat-blocking plate 200 can be felt plates made of heat-resistant fibers. Felt plates are more conducive to blocking airflow than metal meshes. A good airflow can be formed in the smoke collecting hood 300 above the smoke outlet heat-blocking plate 200 to exhaust smoke. The drying barrel chamber 110 below the smoke outlet heat-blocking plate 200 temporarily suspends the airflow, so that the waste ink barrels in the box body 100 can be baked for a longer period of time. In addition, fiber has lower heat dissipation than metal (that is, metal radiates heat faster), and felt plates have better heat preservation. Heat-resistant fibers can be selected from polytetrafluoroethylene fibers, aromatic polyamide fibers, and polyimide fibers with a heat resistance of 250 to 500°C, asbestos fibers, glass fibers, nitrogen boron fibers, and ceramic fibers with a heat resistance of more than 500°C, and carbon fibers and graphite fibers with a heat resistance of 1500 to 3000°C. Preferably, the felt plate is placed in a corresponding mesh frame.

[0040] The tubular electric heating element (referred to as electric heating tube 121) is a metal armored electrical component that converts electrical energy into thermal energy. The electric heating tube 121 uses a metal tube as the outer shell (including stainless steel and copper tubes), and a spiral electric heating alloy wire (such as chromium or iron-chromium alloy) extends along the central axis of the tube. The gaps in the metal tube are filled with compacted magnesium oxide sand with good insulation and good thermal conductivity, and the two ends of the metal tube are sealed with silicone. This kind of metal armored electric heating element can heat air, metal molds and various liquids. Common electric heating tubes 121 include finned electric heating tubes 121, Teflon electric heating tubes 121, quartz electric heating tubes 121, and the like.

[0041] Compared with the prior art, the beneficial effects of the present application include: a heat-resistant plate is provided on the air inlet window and the smoke exhaust window 112 of the box body 100 to slow down the heat loss, making the drying barrel chamber 110 stuffy, and the heat-generating chamber 120 overflows heat to the drying barrel chamber 110 through the metal mesh plate 130, and a number of scattered mesh holes evenly dissipate the hot air, and combined with the high thermal conductivity and high radiation heat of the metal mesh plate 130, it is further ensured that the heat overflows after being evenly distributed, and the relatively uniform heat is blocked for a long time in the drying barrel chamber 110, so that the waste ink barrel 600 is fully and quickly dried, and the residual ink is effectively solidified, which facilitates the full separation of the ink solidification block and the iron material in the magnetic separation and other processes, greatly reducing the difficulty of handling the waste ink barrel 600.

[0042] Reference Figures 1 to 3 In some embodiments of the utility model, a plurality of roller rows 410 arranged along the left-right direction are provided in the drying barrel chamber 110, and a plurality of rollers of a single roller row 410 are arranged along the front-back direction. The roller row 410 is suitable for the waste ink barrel 600 to slide in and out of the drying barrel chamber 110. When a forklift, a barrel moving flat car or a transition ramp is aligned with the operating window 111, the waste ink barrel 600 is pushed, and the waste ink barrel 600 slides in and out of the drying barrel chamber 110 easily.

[0043] Reference Figures 1 to 3 In some configurations, the bottom of the drying barrel chamber 110 is integrally formed with a plurality of mounting grooves 421, and the two ends of each roller lie in the corresponding mounting grooves 421. Preferably, a mounting seat 420 suitable for placing rollers is detachably provided in the drying barrel chamber 110, and the mounting seat 420 is provided with a plurality of mounting grooves 421, and the two ends of the roller lie in the corresponding mounting grooves 421, respectively, so that the disassembly, assembly, maintenance and cleaning of each roller are convenient; the mounting seat 420 can be detached from the drying barrel chamber 110, so that the mounting seat 420 and the drying barrel chamber 110 can be cleaned conveniently.

[0044] Reference Figures 1 to 3 In some embodiments of the present invention, a partition bar 430 is further included. The partition bar 430 is provided with a pin 431 suitable for plugging into the mounting seat 420. The waste ink barrels 600 placed in two adjacent roller rows 410 are separated by the partition bar 430, so that the multiple waste ink barrels 600 in the drying barrel chamber 110 are neatly arranged and separated. Figure 1 and Figure 2 The drying barrel chamber 110 can place 5 groups of waste ink barrels in the left and right directions, and a single group of waste ink barrels has two arranged one in front and one behind; the drying barrel chamber 110 can dry 10 waste oil barrels at a time, and the box body has a vertical height of about 2 meters, a left and right width of about 4 meters, and a front and back width of about 1.8 meters.

[0045] Reference Figures 1 to 3In some embodiments of the present invention, guide slopes are provided on the left and right sides of the front end of the dividing strip 430 to facilitate guiding the waste ink barrel 600 to slide into the corresponding roller row 410. When the dividing strip 430 is plugged into the mounting seat 420, it is also suitable for covering the opening of the corresponding mounting groove 421.

[0046] Reference Figure 2 , Figure 4 In some embodiments of the utility model, the upper and lower ends of the drying barrel chamber 110 are respectively provided with tail heat output holes 113 and tail heat input holes 114, and the box 100 is provided with two tail heat output holes 113 of one box 100 is connected to the tail heat input hole 114 of the other box 100 through a one-to-one corresponding tail heat blower 510. Among the two boxes 100, the box 100 for pre-ending the drying barrel can stop its exhaust fan 310 and transmit tail heat and tail smoke to the box 100 for pre-starting the drying barrel. In the utility model, when the exhaust fan 310 of the box 100 for pre-ending the drying barrel is stopped, the tail heat output hole 113 at the upper end thereof mainly inputs tail heat and tail smoke to the lower end of the box 100 for pre-starting the drying barrel through the corresponding tail heat blower 510, so as to preheat the newly working drying barrel chamber 110, so as to make full use of heat energy and save electricity. During the exhaust heat discharge process, the electric heating tube 121 of the box 100 of the pre-end drying barrel is stopped; when the temperature of the box 100 is lower than the opening threshold, the exhaust heat blower 510 is turned off, and the electric heating tube 121 of the box 100 of the pre-drying barrel and the exhaust fan 310 are turned on.

[0047] In a better barrel drying process, the smoke collecting hood 300 is provided with a smoke sensor. When the oil smoke of the smoke collecting hood 300 of the box 100 for pre-ending the barrel drying is lower than a threshold value, the box 100 for pre-ending the barrel drying can stop its smoke exhaust fan 310 and start to discharge tail smoke to the box 100 for pre-starting the barrel drying; the box 100 for pre-starting the barrel drying starts to start its electric heating tube 121 and the smoke exhaust fan 310; when the oil smoke of the box 100 for pre-ending the barrel drying is lower than a threshold value and the drying time at temperature T satisfies t minutes, its electric heating tube 121 can be stopped; then, when the temperature shown by the box 100 is lower than the opening threshold, its waste ink barrel is opened and taken out.

[0048] In practice, the drying barrel chamber 110 cannot completely exhaust the oil vapor. Every time the drying barrel chamber 110 is opened, a small amount of oil vapor condenses on the inner wall; after repeated accumulation for countless times, a small amount of liquid accumulates on the bottom of the drying barrel chamber 110. In order to avoid large-scale oil pollution in the drying barrel chamber 110 and reduce the labor of oil removal, refer to Figure 2 , Figure 4 In some embodiments of the utility model, an oil collecting groove 115 extending along the inner peripheral wall of the drying barrel chamber 110 is provided at the inner bottom of the drying barrel chamber 110, and the oil collecting groove 115 is suitable for collecting oil sliding down the inner wall of the drying barrel chamber 110, and the drying barrel chamber 110 is provided with a sewage hole connected to the oil collecting groove 115.

[0049] Reference Figure 2 , Figure 4 In some embodiments of the utility model, a horizontal air duct 140 is provided in the drying barrel chamber 110, and a plurality of nozzles 141 suitable for spraying downward into the inner bore of the waste ink barrel 600 are arranged in the horizontal air duct 140. The horizontal air duct 140 is connected to the heating chamber 120 through an intermittent driving fan 520. The intermittent driving fan 520 is suitable for intermittently driving the nozzles 141 to spray hot air into the inner bore of the waste ink barrel 600 to drive away the oil smoke and water vapor in the inner bore of the waste ink barrel 600.

[0050] Reference Figure 1 , Figure 2 and Figure 4 In some embodiments of the present invention, the box body 100 and the smoke collecting hood 300 are detachably connected to jointly clamp the smoke outlet heat blocking plate 200. The smoke collecting hood 300 and the smoke outlet heat blocking plate 200 can be disassembled and assembled simultaneously, and the disassembly, assembly and maintenance thereof are relatively convenient.

[0051] The above embodiments are only used to illustrate the technical solution of the utility model but not to limit it.
