Description

Technical Field

[0001] The utility model relates to the technical field of separation, in particular to a waste gas and waste ink separation system. Background Art

[0002] During the printing and cleaning process, waste gas (such as ozone) and gaseous waste ink are generated. The mixed gas of waste gas and gaseous waste ink floats in the printing area, which will affect the subsequent printing work and the printing quality. Therefore, in order to improve the printing quality, it is necessary to extract and condense the mixed gas of waste gas and gaseous waste ink. The existing separation system relies on multiple filters to grade the mixed gas, which causes the filter layer on the filter to be blocked by the solidified ink, so the filter needs to be replaced frequently, which increases the maintenance cost. Summary of the invention

[0003] In order to solve the above technical problems, the utility model provides a waste gas and waste ink separation system, which can reduce the use of filters and reduce maintenance costs.

[0004] In order to solve the above problems, the utility model adopts the following technical solutions:

[0005] The utility model discloses a waste gas and waste ink separation system, comprising a vortex separator and a blower, the vortex separator comprising a separator body and a waste ink box, the waste ink box is arranged at the bottom of the separator body, a separation chamber is arranged in the separator body, the diameter of the separation chamber gradually increases from bottom to top, a connecting cylinder is arranged at the top of the separation chamber, an air inlet group connected to the connecting cylinder is arranged at the position corresponding to the connecting cylinder at the top of the separator body, a liquid outlet is arranged at the bottom of the separator body, the liquid outlet is connected to the separation chamber, the liquid outlet extends into the waste ink box, a first exhaust port connected to the separation chamber is arranged on the upper part of the outer wall of the separator body, the axis of the first exhaust port does not intersect with the axis of the separation chamber, and the first exhaust port is connected to the air inlet of the blower.

[0006] In the present scheme, the first exhaust port on the separator body is connected with the air inlet of the blower, and the negative pressure generated when the blower is working is used to suck the mixed gas through the air inlet group on the top of the separator body, and the mixed gas enters the lower part of the separation chamber through the connecting tube. Since the first exhaust port is arranged at the upper part of the outer wall of the separator body, the mixed gas contacts the inner wall of the separation chamber and then rises into the first exhaust port. The axis of the first exhaust port does not intersect with the axis of the separation chamber, so in the process of the rising of the exhaust gas, it will generate a spiral wind direction and then become a vortex air duct. Due to the different densities of the exhaust gas and the waste ink, the exhaust gas will be discharged from the first exhaust port along the vortex air duct, and the gaseous waste ink will gradually condense along the inner wall of the separation chamber. The liquid outlet below becomes smaller and smaller, and the condensed waste ink will gradually become larger and more, and rotate downward under the action of gravity. When the gravity of the condensed waste ink is greater than the suction force of the blower, the waste ink can flow out from the liquid outlet into the waste ink box.

[0007] Preferably, the separation chamber is in an inverted cone shape.

[0008] Preferably, the connecting tube is coaxial with the separation chamber.

[0009] Preferably, it also includes a waste ink barrel, wherein a cavity is provided in the waste ink barrel, a drain outlet connected to the cavity is provided at the bottom of the waste ink barrel, an exhaust filter assembly is detachably connected to the top opening of the waste ink barrel, the exhaust filter assembly is used to separate waste gas and waste ink and discharge the separated waste gas out of the waste ink barrel, a waste ink barrel air inlet connected to the cavity is provided on the right side wall of the waste ink barrel, and the waste ink barrel air inlet is connected to the air outlet of the blower.

[0010] Preferably, an opening is provided on the top of the waste ink barrel, and the exhaust filter assembly includes a cover and a filter. The cover is detachably connected to the opening, a second exhaust port for exhaust is provided on the top of the cover, and the filter is arranged at a position corresponding to the second exhaust port at the bottom of the cover.

[0011] Preferably, an outlet cover of the second exhaust port is provided with an outlet connecting ring, the inner wall of the outlet connecting ring is inclined inward from bottom to top, and an annular connecting piece is provided on the top of the outlet connecting ring.

[0012] Preferably, the projection of the filter on the right side wall of the waste ink barrel does not contact the air inlet of the waste ink barrel.

[0013] The exhaust gas after vortex separation in the separator body may still carry some trace amounts of gaseous waste ink. In order to continue to perform secondary separation on the exhaust gas containing trace amounts of gaseous waste ink, a waste ink barrel is provided at the air outlet of the blower. The exhaust gas that has undergone one separation enters the waste ink barrel through the air inlet of the waste ink barrel and collides with the inner wall opposite to the air inlet of the waste ink barrel, and is then discharged through the second exhaust port on the top. At this time, a filter is installed at the second exhaust port. Such a structure will not affect the wind force of the blower's air intake. Trace amounts of waste ink in the exhaust gas will be absorbed by the filter, and all the condensed ink will remain in the waste ink barrel. There is a drain port at the bottom of the waste ink barrel, and the waste ink is discharged to the outside through the drain port.

[0014] The utility model has the beneficial effects that: the separator body can perform primary separation on the mixed gas and discharge the condensed waste ink into the waste ink box; the waste ink barrel can perform secondary separation on the primary separated mixed gas and remove the waste ink in the mixed gas.

A liquid outlet 14 is arranged at the bottom of the separator body 11. The liquid outlet 14 is connected to the separation chamber 111. The liquid outlet 14 extends into the waste ink box 12. A first exhaust port 15 connected to the separation chamber 11 is arranged on the upper part of the outer wall of the separator body 11. The axis of the first exhaust port 15 does not intersect with the axis of the separation chamber 111. The first exhaust port 15 is connected to the air inlet of the blower 2. The separation chamber 111 is in an inverted cone shape, and the connecting cylinder 13 is coaxial with the separation chamber 111.

[0023] It also includes a waste ink barrel 3, which has a cavity inside. A drain outlet 31 connected to the cavity is provided at the bottom of the waste ink barrel 3.

A waste ink barrel air inlet 32 ​​connected to the cavity is provided on the right side wall of the waste ink barrel 3. The waste ink barrel air inlet 32 ​​is connected to the air outlet of the blower 2.

[0024] The waste ink barrel 3 has an opening at the top, and the exhaust filter assembly 4 includes a cover plate 41 and a filter 42. The cover plate 41 is detachably connected to the opening.

[0025] In the present scheme, the first exhaust port on the separator body is connected with the air inlet of the blower. The negative pressure generated by the operation of the blower sucks the mixed gas through the air inlet group on the top of the separator body, and the mixed gas enters the lower part of the inverted cone-shaped separation chamber through the connecting tube. Since the first exhaust port is arranged at the upper part of the outer wall of the separator body, the mixed gas contacts the inner wall of the separation chamber and then rises into the first exhaust port.

The liquid outlet below becomes smaller and smaller, and the condensed waste ink will gradually become larger and more, and rotate downward under the action of gravity. When the gravity of the condensed waste ink is greater than the suction force of the blower, the waste ink can flow out from the liquid outlet into the waste ink box.

At this time, a filter is installed at the second exhaust port. Such a structure will not affect the wind force of the blower's air intake. Trace amounts of waste ink in the exhaust gas will be absorbed by the filter, and all the condensed ink will remain in the waste ink barrel. There is a drain port at the bottom of the waste ink barrel, and the waste ink is discharged to the outside through the drain port.
