Description

The dense scummer of a kind of senior middle school

Technical field

The utility model relates to paper making pulp screening installation technical field, specifically, relates to the dense scummer of a kind of senior middle school.

Background technology

In the process of utilizing waste paper production paper pulp, need to separate a large amount of heavy seeds of containing in the former slip such as the grains of sand, iron sheet, iron filings etc., with the quality that prevents that these heavy seeds from producing wearing and tearing and affecting finished paper equipment, above-mentioned operation realizes by scummer.Scummer generally comprises into slurry head, cone cylinder and slag trapping chamber.

HC Cleaner advances to starch concentration can reach 3～5%, in dense scummer advance to starch concentration and can reach 2～3%,

The principle of the dense scummer of senior middle school is the same with the principle of low dense scummer, if but to advance to starch concentration higher, then contain heavy seeds in the paper pulp more, and fiber is a large amount of the loss easily, and the effect that therefore adopts common scummer that high middle concentration paper pulp is screened is not very desirable.

Summary of the invention

The utility model has overcome defective of the prior art, provides a kind of rational in infrastructure, heavy seeds easily to fall, the dense scummer of senior middle school of the suitable high middle concentration paper pulp slagging-off that fiber loss is less.

The technical solution adopted in the utility model is in order to achieve the above object:

The dense scummer of a kind of senior middle school comprises inlet tube, upper cone, cone cylinder and slag trapping chamber, and inlet tube, upper cone, cone cylinder and slag trapping chamber are affixed successively from top to bottom, and slag trapping chamber top is provided with the elutriation water pipe with slag trapping chamber's intracavity inter-connection.

Further, the slag trapping chamber bottom is provided with the circulating water pipe with slag trapping chamber's intracavity inter-connection.

Further, slag trapping chamber top is provided with the cleaning water pipe with slag trapping chamber's intracavity inter-connection.

Further, eluriate water pipe, circulating water pipe and cleaning water pipe one end and be connected in same white water pipe.

Further, eluriate water pipe, circulating water pipe and cleaning water pipe and respectively be provided with pressure regulation hand valve.

Further, clean water pipe and be provided with electromagnetic valve.

Further, slag trapping chamber arranges double-gate plate valve.

Further, double-gate plate valve is by air cylinder driven.

The beneficial effects of the utility model are:

The utility model is rational in infrastructure, employing arranges the elutriation water pipe on slag trapping chamber top, paper pulp in the cone cylinder is eluriated, to slow down in the speed of the paper pulp of boring the rotation of cylinder high speed, more fiber washed get back in the slurry, reduced the loss of fiber, the slagging-off better effects if is fit to high middle concentration paper pulp slagging-off and uses.

The specific embodiment

Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein only is used for description and interpretation the utility model, and be not used in restriction the utility model.

As shown in Figure 1 and Figure 2, the dense scummer of a kind of senior middle school, comprise inlet tube 1, upper cone 2, cone cylinder 3 and slag trapping chamber 4, inlet tube 1, upper cone 2, cone cylinder 3 and slag trapping chamber 4 are affixed successively from top to bottom, and slag trapping chamber 4 tops are provided with the elutriation water pipe 5 with slag trapping chamber's 4 intracavity inter-connections.

Eluriate water: be equipped with two on the top of cone cylinder 3 bottoms, slag trapping chamber 4 and eluriate water pipe 5.The effect of eluriating water is to slow down in the speed of the slurry of boring the rotation of cylinder 3 high speeds, allows heavy seeds easily fall, and fiber is washed got back in the slurry.

Slag trapping chamber 4 bottoms are provided with the circulating water pipe 6 with slag trapping chamber's 4 intracavity inter-connections.Recirculated water: two circulating water pipes 6 are housed in the bottom of slag trapping chamber 4.Its effect is to keep the slurry circulation, reclaims more multi-fibre.

Slag trapping chamber 4 tops are provided with the cleaning water pipe 7 with slag trapping chamber's 4 intracavity inter-connections.Rinse water: above slag trapping chamber 4, be equipped with and clean water pipe 7.Rinse water mainly is that the bits with slag trapping chamber 4 lavage.Rinse water hydraulic pressure is less than 20 pounds/square inchs, flow 20 gallon per minute.

Elutriation water, rinse water, recirculated water are processed impurity, to reclaim more fiber.

Eluriate water pipe 5, circulating water pipe 6 and clean water pipe 7 one ends and be connected in same white water pipe.Eluriating water pipe 5, circulating water pipe 6 and cleaning water pipe 7 all has hand valve pressure regulation power, eluriates water pipe 5 and often opens with circulating water pipe 6, clean water pipe 7 and be provided with electromagnetic valve, but setting-up time control is opened and is closed, the participation regular cinder-discharge.

Slag trapping chamber 4 arranges double-gate plate valve 8.

Double-gate plate valve 8 is by air cylinder driven.

Timing automatic deslagging: collection and the discharging of slag trapping chamber's 4 usefulness double-gate plate valves, 8 control bits, the action of double-gate plate valve 8 is by air cylinder driven.The deslagging time can set up on their own.During collecting bits, upper valve is opened, and lower valve closes, and heavy slag enters slag trapping chamber 4, and setting-up time arrives, and upper valve closes, and lower valve is opened, and heavy slag is discharged, and slag trapping chamber 4 is by the rinse water wash clean.During moving, guarantee that a valve another valve before beginning to open closes fully.

It should be noted that at last: above only is preferred embodiment of the present utility model, be not limited to the utility model, although with reference to embodiment the utility model is had been described in detail, for a person skilled in the art, it still can be stated scheme to the skill that aforementioned each embodiment puts down in writing and make amendment, and perhaps part technical characterictic wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
