Description
Technical Field
[0001] The utility model relates to the field of inkjet printing equipment, in particular to an ink ultrasonic dispersion and screening system. Background Art
[0002] An inkjet printer sprays fine droplets of colored liquid ink onto printing paper through nozzles. Some inkjet printers have multiple printing nozzles to print multiple colors.
[0003] Among them, some of the ink materials required for inkjet printing are solid inks, and the solid inks need to be processed by a spheroidizing device before they can be used. However, after the existing solid inks are processed by the spheroidizing device, some of the inks will have uneven dispersion of spheroidizing particles, resulting in more or larger particles in the ink, which in turn affects the smoothness of inkjetting. Content of the Utility Model
[0004] The purpose of the utility model is to provide an ink ultrasonic dispersion and screening system that can improve the filtering effect of ink and effectively avoid ink from being unable to be filtered normally due to filter blockage.
[0005] To solve the above technical problems, the utility model provides an ink ultrasonic dispersion and screening system, which includes an ink tank, an ultrasonic disperser connected to one side of the ink tank. An outlet and an inlet are provided on the side of the ink tank, and an outlet pipeline is connected to the outlet, and an inlet pipeline is connected to the inlet. The first filter element, the second filter element and the third filter element are arranged in parallel between the outlet pipeline and the inlet pipeline, so that the first filter element and the ink tank form a first filtering loop, the second filter element and the ink tank form a second filtering loop, and the third filter element and the ink tank form a third filtering loop. Moreover, the first filter element, the second filter element and the third filter element are all provided with a backwashing mechanism to clean each filter element.
[0006] Furthermore, valves are provided at both the inlet end and the outlet end of the first filter element, the second filter element and the third filter element.
[0007] Furthermore, the backwashing mechanism includes a backwashing port and a pressure relief port provided on one side of the first filter element or the second filter element or the third filter element, so that the backwashing port intakes air and the pressure relief port exhausts air, and the air intake direction of the backwashing port is opposite to the filtering direction.
[0008] Furthermore, the backwashing mechanism further includes a recovery bottle detachably provided on one side of the first filter element or the second filter element or the third filter element, so that when the backwashing port intakes air for backwashing, the blockage falls into the recovery bottle.
[0009] Furthermore, a differential pressure detection component is connected between the outlet and the inlet, which is used to detect the pressure difference between the outlet and the inlet, and the differential pressure detection component is electrically connected to the backwashing mechanism.
[0010] Further, one end of the liquid outlet pipeline is provided with a liquid discharge valve, so that after the ink filtration is completed, it is discharged outward through the liquid discharge valve.
[0011] Further, a pump body is connected between the liquid outlet pipeline and the liquid outlet.
[0012] Further, a stirring rod is rotatably arranged inside the ink tank.
[0013] Further, the filtration particle sizes of the first filter element, the second filter element, and the third filter element gradually decrease.
[0014] Further, a water chiller is connected to one side of the ink tank.
[0015] The beneficial effects of the present utility model are as follows: The ink after spheroidizing is placed in the ink tank, and the ink in the ink tank is ultrasonically oscillated by an ultrasonic disperser, so that the ink is subjected to the high pressure and impact generated by ultrasonic cavitation to improve the dispersion uniformity of the particles in the ink. At the same time, the ink in the ink tank is sequentially filtered through the first filtration circuit, the second filtration circuit, and the third filtration circuit for multi-stage filtration. After the ink is multi-stage filtered, particles with larger particle sizes can be effectively screened out, improving the smoothness and stability during ink printing.
[0016] Moreover, due to the setting of the backwashing mechanism, after the multi-stage filtration circuit filters and uses the ink for a certain period of time, the position of the filter element can be backwashed by the backwashing mechanism, so that the particulate matter remaining at the filter element can be blown off, avoiding the situation that the particulate matter blocks the filter element, resulting in incomplete filtration or inability to be used normally.

Detailed Embodiments

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present utility model.
[0020] Those skilled in the art should understand that in the disclosure of this utility model, the orientation or positional relationship indicated by terms such as "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing this utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.
[0021] It can be understood that the term "one" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of an element can be one, while in other embodiments, the number of this element can be multiple. The term "one" should not be construed as a limitation on the quantity.
[0022] As Figure 1 As described above, this utility model provides an ink ultrasonic dispersion and screening system, which includes an ink tank 1, an ultrasonic disperser 2 connected to one side of the ink tank 1. An outlet 3 and an inlet 4 are provided on the side of the ink tank 1. And an outlet pipeline 5 is connected to the outlet 3, and an inlet pipeline 6 is connected to the inlet 4. The first filter element 7, the second filter element 8 and the third filter element 9 are arranged in parallel between the outlet pipeline 5 and the inlet pipeline 6, so that the first filter element 7 and the ink tank 1 form a first filtration loop, the second filter element 8 and the ink tank 1 form a second filtration loop, and the third filter element 9 and the ink tank 1 form a third filtration loop. And the first filter element 7, the second filter element 8 and the third filter element 9 are all provided with a backwashing mechanism to clean each filter element by the backwashing mechanism.
[0023] Place the ink after spheroidizing in the ink tank, and perform ultrasonic oscillation on the ink in the ink tank through the ultrasonic disperser. Then, the ink is subjected to the high pressure and impact generated by ultrasonic cavitation to improve the dispersion uniformity of the particles in the ink. At the same time, the ink in the ink tank is sequentially filtered through the first filtration loop, the second filtration loop and the third filtration loop for multi-stage filtration. After the ink passes through multi-stage filtration, particles with larger particle sizes can be effectively screened out, improving the smoothness and stability during ink printing.
[0024] Moreover, due to the setting of the backwashing mechanism, after the multi-stage filtration loop filters and uses the ink for a certain period of time, the backwashing mechanism can backwash the position of the filter element, so that the particulate matter remaining at the filter element can be blown off, avoiding the situation that the particulate matter blocks the filter element and causes incomplete filtration or abnormal use.
[0025] Among them, when the ink is filtered, it uniformly flows out from the liquid outlet, flows along the liquid outlet pipeline to one of the filter elements, and after passing through the filter element, it flows along the liquid inlet pipeline to the liquid inlet and enters the ink tank, and the ink is filtered in multiple stages along the first filter element, the second filter element, and the third filter element in sequence.
[0026] In an embodiment of this solution, the filtration particle sizes of the first filter element 7, the second filter element 8, and the third filter element 9 gradually decrease, so that when the ink is filtered in multiple stages, larger particle-sized particles can be gradually screened out, and the particle dispersion uniformity in the ink can be gradually improved.
[0027] Preferably, valves 10 are provided at both the liquid inlet end and the liquid outlet end of the first filter element 7, the second filter element 8, and the third filter element 9.
[0028] Specifically, by controlling the opening and closing of the first filter element, the second filter element, and the third filter element through the valves, the first filter element, the second filter element, and the third filter element can be opened separately, avoiding the situation where the filtering effect deteriorates due to the synchronous opening of multiple filter elements.
[0029] Preferably, the backwashing mechanism includes a backwashing port 11 and a pressure relief port 12 provided on one side of the first filter element 7 or the second filter element 8 or the third filter element 9, so that air enters through the backwashing port 11 and exhausts through the pressure relief port 12, and the air inlet direction of the backwashing port 11 is opposite to the filtering direction.
[0030] Specifically, when cleaning a specified filter element, the corresponding backwashing port is opened, so that the backwashing port blows air into the interior of the specified filter element. Since the air inlet direction is opposite to the filtering direction, the air blown by the backwashing port can blow off the particulate matter remaining on the filter element, avoiding the situation where a large amount of particulate matter blocks the filter element. At the same time, the pressure relief port exhausts the gas blown into the backwashing port to avoid excessive air pressure inside the filter element affecting subsequent filtration.
[0031] Among them, the backwashing port is connected to the gas supply device through a pulse valve to ensure stable gas supply at the backwashing port.
[0032] Preferably, the backwashing mechanism further includes a recovery bottle 13 detachably provided on one side of the first filter element 7 or the second filter element 8 or the third filter element 9, so that when the backwashing port 11 performs air inlet backwashing, the blockage falls into the recovery bottle 13.
[0033] Specifically, when the backwashing port backwashes and cleans the position of the filter element, the particulate matter remaining at the filter element will be blown off into the recovery bottle, avoiding a large amount of particles entering the pressure relief port and causing blockage of the pressure relief port. At the same time, it is also beneficial to uniformly clean the blockage after detaching the recovery bottle later, ensuring the long-term use of the backwashing mechanism.
[0034] In an embodiment of this solution, a filter screen or a component with a filtering effect can be provided at the pressure relief port to ensure that particulate matter does not enter the pressure relief port. At the same time, the filter element is set to be detachably connected to ensure that the filter screen at the pressure relief port can be replaced regularly.
[0035] Preferably, a differential pressure detection component 14 is connected between the liquid outlet 3 and the liquid inlet 4 for detecting the pressure difference between the liquid outlet 3 and the liquid inlet 4, and the differential pressure detection component 14 is electrically connected to the backwashing mechanism.
[0036] Specifically, the differential pressure detection component is used to detect the differential pressure between the liquid outlet and the liquid inlet of the ink tank. When the differential pressure between the two is too large, it can indicate that the filter element is blocked, the pipeline is leaking, etc. Then, the backwashing mechanism is controlled to backwash and clean the filter element to ensure that the differential pressure between the liquid outlet and the liquid inlet will not be too large.
[0037] Among them, the differential pressure detection component can adopt pipeline pressure detection equipment such as a pressure gauge. And by setting a differential pressure value, when the detected differential pressure is greater than the set differential pressure, the differential pressure detection component transmits a signal to the backwashing mechanism to control the backwashing mechanism to be turned on for a set time or until the detected differential pressure is lower than the set differential pressure by a certain value.
[0038] Preferably, one end of the liquid outlet pipeline 5 is provided with a drain valve 15 so that after the ink filtration is completed, it can be discharged outward through the drain valve 15.
[0039] Specifically, after the ink passes through multiple-stage filtration, the ink tank reopens the liquid outlet, so that the ink flows from the liquid outlet along the liquid outlet pipeline to the drain valve. At this time, the drain valve is opened and the valves at all filter elements are closed, so that the filtered ink is discharged from the drain valve to a specified position to ensure that the filtered ink can be used.
[0040] Preferably, a pump body 16 is connected between the liquid outlet pipeline 5 and the liquid outlet 3.
[0041] Specifically, the pump body provides power for the flow of the ink to ensure that the ink can stably flow through the multi-stage filter elements, thereby ensuring the filtering effect.
[0042] In an embodiment of this solution, the pump body can adopt a peristaltic pump.
[0043] Preferably, a stirring rod 17 is rotatably arranged inside the ink tank 1.
[0044] Specifically, by rotating the stirring rod inside the ink tank, the stirring rod agitates the ink to prevent the particles inside the ink from precipitating and accumulating, so as to ensure the filtering effect.
[0045] Among them, the stirring rod can adopt forms such as pneumatic and electric.
[0046] Preferably, a water chiller 18 is connected to one side of the ink tank 1 to enable the water chiller to control the temperature of the ink in the ink tank.
[0047] The present utility model is not limited to the above-mentioned optimal implementation mode. Any person can obtain other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in its shape or structure, as long as it has a technical solution identical or similar to that of the present application, it falls within the protection scope of the present utility model.
