Description
Technical field
The present invention relates to the technical fields of filter plant, more particularly, to a kind of printing developer solution circulating filtration equipment.
Background technique
Platemaking machine is plate making equipment, printing CTP editions needed during development with a large amount of clear water to the space of a whole page into
Row rinses, and every square metre needs about 3--5 liters of clear water, since printer does not configure circulating filtration function, so as to cause sewage
Discharge, causes environmental pollution.
By taking a medium-sized printing house as an example, about 800--1500 square meter of making a plate daily, water consumption about 4000-6000 liter does not have
It recycles, results in waste of resources.Therefore the equipment of a kind of pair of developer solution circulating filtration is needed, water utilization rate is improved.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to provide a kind of printing developer solution circulating filtration to set
It is standby, there is preferable filter effect, and equipped with the function of prompting changing filter packing.
A kind of printing developer solution circulating filtration equipment, including filter vat, centrifugal pump, be communicated at the outlet of centrifugal pump into
Liquid pipe, the filter vat opening are removably connected with bung, and the bung is fixed with screen pipe, and described screen pipe one end is pierced by
Bung is connected to the inlet tube, and the other end extends to filter vat bucket bottom, and the bung side is also through with liquid outlet, it is described go out
Liquid mouth is connected to the filter vat；Active carbon is filled in the filter vat, the inlet tube is provided with monitoring system.
By above-mentioned setting, which includes being loaded with filter vat and the centrifugation of active carbon
Pump, the water inlet of centrifugal pump are connected to the water tank for containing circulation fluid, and the outlet of centrifugal pump has inlet tube, by centrifugal pump
Pressurization and water conservancy diversion are carried out to damping circulation fluid, driving damping circulation fluid circulates.Filter vat opening is threaded with bung,
Bung is fixed with screen pipe, and one end of screen pipe is pierced by bung and is connected to the inlet tube outside bung, the other end out of filter vat to
Bucket bottom extends, wherein being also through with liquid outlet in the side of filter vat, is connected to inside liquid outlet and filter vat.To circulation fluid
Flow direction is to pump out from centrifugal pump, is circulated to filter vat bucket bottom through inlet tube and screen pipe, with the liquid level in filter vat by
It edges up and up to fills up filter vat, and flowed out from the liquid outlet of bung, circulation fluid is filtered by the active carbon in filter vat.
Screen pipe is extended to the over to the bucket bottom of lauter tub, and pushes up circulation fluid in such a way that centrifugal pump pressurizes, by active carbon
The mode flowed out afterwards from liquid outlet, makes circulation fluid pass through the maximum active carbon layer of thickness as much as possible, makes filter effect more preferably.And
And because water (flow) direction is upward from bucket bottom, and the solid impurity in recirculated water has the tendency that precipitating under self gravitation effect, from
And the filter effect to impurity in circulation fluid is can be improved into the contrary setting of water (flow) direction and precipitating.Wherein inlet tube is also
It is provided with monitoring system, monitoring system incudes the tube wall pressure of inlet tube, because of the situation identical in the working efficiency of centrifugal pump,
According to Bernoulli's theorem, in the case that the gap of active carbon is gradually filled up by impurity, permeable effect is gradually reduced, at inlet tube
Water flow pressure will be gradually increased, thus by measurement inlet tube tube wall pressure with one determination value compare, work as inlet tube
Tube wall pressure is greater than the determination value then monitoring system alarming, and user is reminded to replace active carbon.Active carbon particle small volume, phase
