The preferred embodiment that embodiment 1 is many rotary drums of the present invention washing separation device.
embodiment of the method 3:this is the embodiment of many rotary drums material washing separating method:
Described mixed material is the solid gurry in paper mill, and main component is polypropylene film class waste or used plastics sheet and wet-strength paper sheet, and first kind material is wet-strength paper sheet, and Equations of The Second Kind material is polypropylene film class waste or used plastics tablet.The washing that many rotary drums washing separation device that operative installations embodiment 1 provides herein carries out the solid gurry in paper mill separates: the external circe speed of three rotary drums that set gradually between charging aperture and discharging opening is made as 1.2m/s, over dry mixed material and washings weight ratio are 3:97, and wash concentration is 3%.
Mixed material is added to washing cavities by the charging aperture of many rotary drums washing separation device; From many rotary drums washing separation device, water inlet injects when washings, and from each of many rotary drums washing separation device, water inlet injects the washings that up flow velocity is 0.01m/s ~ 0.3m/s.
Because the proportion of wet-strength paper sheet is greater than 1, and the proportion of polypropylene film class waste or used plastics sheet is less than the proportion of wet-strength paper sheet, within the up flow velocity of the washings that water inlet from each is injected is made as 0.01m/s ~ 0.3m/s (containing 0.01m/s and 0.3m/s), can make the impulse force of up current in each body be less than the poor of the gravity of wet-strength paper sheet in water and buoyancy, be greater than the poor of the gravity of film class waste or used plastics sheet in water and buoyancy simultaneously.The wet-strength paper sheet mixing like this and waste or used plastics sheet, wash, break up through homodromal multiple rotary drums, in washing cavities, separates gradually; Wet-strength paper sheet is due to water suction profit, in each body, slowly in up current, sinks down into gradually jetsam pipe, and film class waste or used plastics tablet is not because absorb water and proportion gentlier floats on the water surface, pulled over and moves forward to discharging opening by homodromal multiple rotary drums.
Be 1m/s at the external circe speed of rotary drum, over dry mixed material and washings weight ratio are 3:97, be that wash concentration is to test under 3% wash conditions, experimental results show that, within the up flow velocity of the washings that each lower water inlet injects is made as 0.01m/s ~ 0.3m/s, the wet-strength paper sheet of realizing that can be appropriate separates with the effective of film plastic tablet, otherwise up flow velocity is excessive, can form too high impulse force and affect separating effect the wet-strength paper sheet of sedimentation; And under the effect of up current, with rotary drum rotate washing film class waste or used plastics tablet seldom from each frustum mouth enter in body, also can be by the washing cavities of slowly up current refunds body even if fall into, therefore do not have up flow velocity or up flow velocity too small, can not effectively anti-the film plastic tablet that is strayed into body with current sending back in washing cavities be pulled over toward outbound course.Take full advantage of the difference of specific gravity of wet-strength paper sheet, plastics tablet and water, the effective washing that realizes wet-strength paper sheet and plastic film chip with separate.
In this method embodiment along the mixed material horizontal feed direction of many rotary drums washing separation device, the up flow velocity of the washings that water inlet injects from each successively decreases successively, first lower water inlet injects the washings that up flow velocity is 0.3m/s, second lower water inlet injects the washings that up flow velocity is 0.2m/s, and the 3rd lower water inlet injects the washings that up flow velocity is 0.15 m/s.When mixed material has just entered washing cavities like this, not yet obtain fully water suction profit, also not yet obtaining washing fully breaks up, more or meromict state, cleannes do not reach requirement yet, the up flow velocity of first lower water inlet is relatively large, the impulse force of the up current that bring is also larger, therefore wash, break up, separate through rotary drum the small part water suction profit comparatively sufficient wet-strength paper sheet obtaining, can by first body slowly up current sink gradually, and the material of meromict state cannot sink; And then the washing control zone that mixed material is pulled over to follow-up rotary drum is continued washing, is broken up, further water suction profit is disperseed more fully, the material of meromict state reduces gradually, the up flow velocity of the washings that each lower water inlet injects successively decreases successively, can make profit open, break up, separate to such an extent that follow-up each body that passes through that wet-strength paper sheet progressively increases comparatively fully deposits gradually, thereby obtain better laddering separation and incremental deposition effect.
Final film class waste or used plastics tablet is pulled over and is moved forward to discharging opening by multiple rotary drums, discharge, and the sedimentation of moisture wet-strength paper sheet is accumulated in each jetsam pipe with washings, is is alternately opened and closed and discharges by loading and unloading material valve and lower discharge valve.
Described loading and unloading material valve and lower discharge valve replace method for opening and closing and are: open the each loading and unloading material valve on many rotary drums washing separation device, close each lower discharge valve, deposit first kind material in jetsam pipe; Close the each loading and unloading material valve on many rotary drums washing separation device, open each lower discharge valve, from jetsam pipe, discharge first kind material; And then open each loading and unloading material valve, close each lower discharge valve, deposition first kind material; And then close each loading and unloading material valve, and open each lower discharge valve, discharge first kind material, so alternately repeatedly open and close upper and lower discharge valve according to certain hour interval.
embodiment of the method 4:this is the embodiment of many rotary drums material washing separating method, and basic identical with the detailed description of the invention of embodiment of the method 3, something in common is not repeated, and difference is:
Described mixed material is the solid gurry in paper mill, and main component is polyethylene film class waste or used plastics sheet and the scraps of paper, and first kind material is the scraps of paper, and Equations of The Second Kind material is the polyethylene film class waste or used plastics tablet that proportion is less than scraps of paper proportion.
The washing that many rotary drums washing separation device that operative installations embodiment 2 provides herein carries out the solid gurry in this paper mill separates: the external circe speed of five rotary drums that set gradually between charging aperture and discharging opening is made as 1.2m/s.
Over dry mixed material and washings weight ratio are 5:95, and wash concentration is 5%.
By the automatic buildup of automatic valve, discharging, and by current velocity controller and the interior current meter arranging of each body at each lower mouth of a river, come more accurately to observe easily, control flow rate of water flow, in this method embodiment along mixed material horizontal feed direction, the up flow velocity of the washings that water inlet injects from each successively decreases successively, first lower water inlet injects the washings that up flow velocity is 0.3m/s, second lower water inlet injects the washings that up flow velocity is 0.2m/s, the 3rd lower water inlet injects the washings that up flow velocity is 0.15 m/s, the 4th lower water inlet injects the washings that up flow velocity is 0.1 m/s, the 5th lower water inlet injects the washings that up flow velocity is 0.05 m/s.
