Description

Self-cleaning filter vat for printing machine water tank system

Technical Field

The utility model relates to a technical field of printing, in particular to a self-cleaning formula filter vat for printing machine water tank system.

Background

The fountain solution is an indispensable chemical assistant in printing of color press, and forms a uniform water film on the blank part of the printing plate to resist the ink on the picture and text from infiltrating into the blank part and prevent the plate from being dirty. The fountain solution needs to be diluted before use because of its high concentration. In order to not affect the effect of the fountain solution, the water source for diluting the fountain solution needs to be kept pure, so that the water source needs to be filtered and purified before being introduced. The water source after purifying is introduced into the mixing drum through the metering component, and simultaneously, the staff introduces fountain solution and alcohol into the mixing drum, and the three are stirred according to a certain proportion to form chemical auxiliary agents capable of being supplied to a printing machine.

Referring to fig. 1, in the prior art, a purification system for a water source generally comprises a primary filter 8, a middle-stage filter 9 and an ultrafiltration membrane filter 10, wherein the primary filter 8 is composed of a plurality of cotton filter elements, and the middle-stage filter 9 is composed of a plurality of PP melt-blown filter elements. After the water source passes through the cotton filter element and the PP melt-blown filter element, particle impurities in the water source are filtered, then the water source enters the ultrafiltration membrane filter 10, and metal impurities in the water source are filtered through the ultrafiltration membrane. And the water source purification is realized through three filtering processes so as to meet the water source requirement of diluting the fountain solution.

The water source used conventionally is usually tap water, after the tap water comes out from a tap water plant, the tap water still contains more particle impurities, and when the primary filtration 8 is carried out, the cotton filter element plays a role in adsorbing most of the particle impurities in the water, so that the cotton filter element is easy to attach more pollutants.

The bottom of the barrel body 1 is provided with a waste water pipe 14, the waste water pipe 14 is positioned among the cotton filter elements 2, and the waste water pipe 14 is used for discharging unpurified water sources in the barrel body 1. And the purified water pipe 13 and the waste water pipe 14 are respectively provided with an opening and closing ball valve 15. In order to prevent the purified water pipe 13 and the waste water pipe 14 from abutting against the ground, a support frame 16 is fixedly connected to the bottom of the tub 1.

Referring to fig. 3, a spraying ring pipe 5 is fixedly connected to a position of the inner side wall of the barrel body 1 lower than the top end of the cotton filter element 2, and a nozzle 51 facing the cotton filter element 2 is communicated with the spraying ring pipe 5. A water inlet pipe 52 is arranged outside the barrel body 1, and the water inlet pipe 52 is communicated with the spray ring pipe 5. In the use, when cotton filter core 2 saturation, the external pure water of staff, the pure water passes through the oral siphon 52 and gets into in the spray ring pipe 5, and through the pressure boost of booster pump, the pure water can have the certain speed and spray towards cotton filter core 2, and the pure water attaches the bottom that falls staving 1 with the impurity on cotton filter core 2 surface to discharge through waste pipe 14. In order to reduce the impact force between the spray head 51 and the cotton filter element 2 and reduce the probability of the cotton filter element 2 being damaged by washing, the contact angle between the spray head 51 and the cotton filter element 2 is 15 degrees.

Referring to fig. 2, a steam pipe 6 is communicated with the top of the upper cover 4 (refer to fig. 3), and the steam pipe 6 is communicated with the axis of the cotton filter element 2 (refer to fig. 3). The steam pipe 6 is connected in parallel with a water filling pipe 61, and the water filling pipe 61 and the steam pipe 6 are respectively provided with a stop valve 62. External steam enters the cotton filter element 2 (refer to fig. 3) through the steam pipe 6, and the opening and closing ball valve 15 is closed at the moment. Steam overflows to the outside by cotton filter element 2's inside to ejecting to cotton filter element 2 surface with the impurity in the cotton filter element 2. After the steam is conveyed, water is continuously filled into the water filling pipe 61, so that impurities in the cotton filter element 2 further overflow. Then water is filled towards the spray ring pipe 5, so that the impurities on the surface of the cotton filter element 2 are washed by water flow.

Referring to fig. 3, a degreasing ring pipe 7 is fixedly connected to the lower portion of the spraying ring pipe 5 inside the barrel body 1, the degreasing ring pipe 7 is provided with an atomizing nozzle 71 facing the cotton filter element 2, a degreasing tube 72 is arranged outside the barrel body 1, and the degreasing tube 72 is communicated with the degreasing ring pipe 7. Outside degreasing fluid gets into degreasing ring pipe 7 through degreasing tube 72 in, through the pressure boost of booster pump for degreasing fluid can spout cotton filter element 2 with certain speed, thereby has realized the purification treatment to cotton filter element 2 surface grease. After the oil liquid is sprayed, purified water is sprayed again through the spraying ring pipe 5, so that the cotton filter element 2 is cleaned.

The specific implementation process comprises the following steps:

1. opening the stop valve 62 on the steam pipe 6, filling steam towards the cotton filter element 2, pressing impurities in the cotton filter element 2 out of the cotton filter element 2 by the pressure of the steam, then closing the stop valve 62 on the steam pipe 6, opening the stop valve 62 on the water inlet pipe 6141, filling purified water towards the cotton filter element 2 through the water inlet pipe 6141, and further extruding the impurities in the cotton filter element 2 under the pressure of the water;
