Abstract
The utility model relates to a pressure screen of a papermaking machine. The pressure screen comprises a shell, a screen drum rotatably mounted in the shell, and an ultrasonic vibrator fixed on the shell and connected with the bottom of the screen drum, wherein a pulp inlet and a slag discharge port are respectively formed on the two sides of the shell; and a pulp outlet communicated with the screen drum is formed above the shell. Pulp enters the shell from the pulp inlet; after the pulp is filtered by the screen drum rotating at a high speed, impurities are discharged from the slag discharge port; and the filtered pulp is discharged from the pulp outlet. When the screen drum is blocked and the filtering effect is influenced, the ultrasonic vibrator can be started to drive the screen drum to vibrate so as to realize an effect of vibrating off the impurities blocking screen holes. The time and labor are saved in cleaning, and the production efficiency is improved.
Description
Technical field
The utility model relates to pulp technology for making paper, is specifically related to a kind of pressurized screen.
Background technology
In paper industry, need the working pressure sieve with the impurity in filter paper pulp, but, after using a period of time, impurity can be attached on the screen drum surface of pressurized screen, thereby stop up sieve aperture.Now just need stop cleaning, thereby increased the non-programmed halt number of times, briefly produce, affected production efficiency.
Summary of the invention
The utility model, in order to overcome the deficiency of above technology, provides a kind of paper machine pressurized screen that effectively prevents that screen drum from stopping up.
The utility model overcomes the technical scheme that its technical problem adopts:
This paper machine pressurized screen, comprise housing, rotate the screen drum be installed in housing, be fixed on housing and be connected in the ultrasonic vibrator of screen drum bottom, described housing both sides are respectively arranged with stock inlet and slag-drip opening, and the top of described housing is provided with the grout outlet be communicated with screen drum.
In order to realize automatically controlling cleaning, in above-mentioned grout outlet, flow sensor is installed, described flow sensor and ultrasonic vibrator all are connected in single-chip microcomputer.
The beneficial effects of the utility model are: paper pulp enters into housing from stock inlet, and after the screen drum of High Rotation Speed filters, impurity is discharged by slag-drip opening, and the paper pulp after filtration is discharged by grout outlet.If, when screen drum congestion affects filter effect, can open ultrasonic vibrator, the unlatching ultrasonic vibrator drives screen drum to produce vibration, thereby reach the impurity that will stop up sieve aperture, vibrates the effect come off.Cleaning is time saving and energy saving, has improved production efficiency.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is control system theory diagram of the present utility model;
In figure, 1. housing 2. screen drum 3. stock inlet 4. slag-drip opening 5. ultrasonic vibrator 6. flow sensor 7. grout outlets.
The specific embodiment
Below in conjunction with accompanying drawing 1,2 pairs of the utility model of accompanying drawing, be described further.
This paper machine pressurized screen, comprise housing 1, rotate the screen drum 2 be installed in housing 1, be fixed on housing 1 and be connected in the ultrasonic vibrator 5 of screen drum 2 bottoms, described housing 1 both sides are respectively arranged with stock inlet 3 and slag-drip opening 4, and the top of described housing 1 is provided with the grout outlet 7 be communicated with screen drum 2.Paper pulp enters into housing 1 from stock inlet 3, and after the screen drum of High Rotation Speed filters, impurity is discharged by slag-drip opening 4, and the paper pulp after filtration is discharged by grout outlet 7.If, when screen drum congestion affects filter effect, can open ultrasonic vibrator 5, unlatching ultrasonic vibrator 5 drives screen drums to produce vibration, thereby reach the impurity that will stop up sieve aperture, vibrates the effect come off.Cleaning is time saving and energy saving, has improved production efficiency.
In above-mentioned grout outlet 7, flow sensor 6 is installed, described flow sensor 6 and ultrasonic vibrator 5 all are connected in single-chip microcomputer.When screen drum 2 stops up, the pulp flow flowed out from grout outlet will reduce, and flow sensor 6 detects after flow reduces and feeds back to single-chip microcomputer, and the Single-chip Controlling ultrasonic vibrator starts, thereby realizes the cleaning of screen drum 2, has realized the purpose of automatic control.
