Abstract

The utility model relates to a novel single-belt ultra pressure sludge dewatering machine which is composed of a regulation slot, a transmission screen, a gravity dewatering part, a main roll, driving rolls, a drive motor and chains, wherein the drive motor and the chains are arranged on the main roll with wide caliber and directly drive the main roll. A group of ultra pressure rolls are additionally arranged below the main roll. The screen is arranged between the ultra pressure rolls and the main roll, so the pressure is added on the screen by the main roll with wide caliber and the ultra pressure rolls. The frictional forces are produced to drive the screen to move towards. The screen moves on under the action of the frictional forces, so the utility model can not slip and can solves the problem that the machine can not work with slipping.

Description

Single-belt ultrapressure sludge dewatering machine

The utility model relates to sludge treatment device, refers to a kind of novel single belt super-pressure sludge dewatering equipment especially.

Along with the reinforcement of environmental consciousness, handle problems for the mud waste water that intense industrialization brought, increasingly important, general roughly as follows to the handling procedure of mud waste water:

In above-mentioned flow chart: the phase I gives birth to the water of releasing and can directly discharge, mud then must be through the processing again of second stage--dehydration--afterwards, impel wherein that water content reaches minimum situation, residue is pressed into flat, thin sludge cake and being beneficial to is buried, and incinerates or solidifies; The water recirculation of being taken off then enters the handling procedure of phase I; Whole flow process is a closed circulatory system.

Referring to Fig. 5 is a kind of single strainer sludge dewatering equipment structure of generally using on the market at present, wherein after mud enters from entering the mouth, can utilize the single strainer kind of drive drive mud after a gravity dehydration is handled again with a pre-pressing roller, the pressure agent effect of the pressure of giving birth between one pressure roller and main roller impels mud to discharge wherein contained moisture; Again last mud is crushed to sludge cake, general moisture content is about 85%, and the height of sludge cake moisture content is inversely proportional to the size that sludge cake bears squeeze force, and squeeze force is bigger, and the sludge cake moisture content is just lower; Otherwise, as the same.

General traditional single strainer sludge dewatering equipment, whether smooth and easy its strainer advance is by driving rolls 6 and 2 formed frictional force F of strainer, and main roller 4 and pressure roller 5a, the resistance R that squeeze pressure produced between the 5b, the size that concerns is between the two judged.Under the normal condition, frictional force greater than resistance (F＞R), just can impel strainer 2 to advance, when squeeze pressure increased, the resistance R that is produced also increased thereupon; When in a single day its resistance R is increased to when being equal to or greater than frictional force F, promptly during R 〉=F, strainer 2 just very easily skids, and causes machine to work; Prerequisite F＞the R of single in a word strainer sludge dewatering equipment running, wherein squeeze pressure and frictional force F are inversely proportional to, and are directly proportional with resistance R; Therefore want to keep machine and run well, its squeeze pressure can not be too high because of the restriction that is subjected to frictional force, and causing the sludge cake moisture content of making still is about 85%.

The purpose of this utility model is: cause strainer to skid at above-mentioned R 〉=F, the problem that machine can't be worked is driven strainer from the structure renewal referring to Fig. 1 by main roller 4 and 2 formed frictional force F of strainer during advancing; While main roller 4 and hyperpressure roller 5a, 5b, 5c, pressure between 5d also helps improving frictional force F, promptly when squeeze force increases, frictional force F also increases thereupon, strainer 2 can not produced skid, the problem that machine can't be worked, and can improve squeeze pressure its sludge cake moisture content of making is reduced to about 75%.

The purpose of this utility model is achieved in that a kind of novel single belt super-pressure sludge dewatering equipment is by conditioning groove 1, transmission strainer 2, gravity dehydration portion 3, main roller 4, driving rolls 6, CD-ROM drive motor 7 and chain 8 are formed, it is characterized in that: CD-ROM drive motor 7 places on the bigbore main roller 4 with chain 8, and directly drive main roller 4, set up one group of hyperpressure roller 5a, 5b, 5c in the below of main roller 4,5d strainer 2 places between the two, and the frictional force that causes heavy caliber main roller 4 and hyperpressure roller to stress on 2 generations of strainer drives strainer 2 and advances.

Advantage of the present utility model is: strainer drives according to frictional force F in advancing, because the pressure between main roller and the formed frictional force F of strainer and main roller and hyperpressure roller all improves the value of frictional force F, strainer is constantly advanced under the effect of F power, can not produce and skid, the problem that machine can't be worked can make the sludge cake moisture content reduce to about 75% simultaneously.

Concrete structure of the present utility model further specifies by the following drawings and embodiment:

Fig. 1 is the utility model combining structure flow chart.

Fig. 2 is the location drawing of the utility model motor and chain.

Fig. 3 is the utility model sludge cake Way out stereogram.

Fig. 4 is the utility model mud Way in stereogram.

Fig. 5 has single strainer sludge dewatering equipment combining structure flow chart now.

The location drawing of existing single strainer sludge dewatering equipment motor of Fig. 6 and chain.

Referring to Fig. 1: a kind of novel single belt super-pressure sludge dewatering equipment is by conditioning groove 1, transmission strainer 2, gravity dehydration portion 3, main roller 4, driving rolls 6, CD-ROM drive motor 7 and chain 8 are formed, it is characterized in that: CD-ROM drive motor 7 places on the bigbore main roller 4 with chain 8, and directly drive main roller 4, set up one group of hyperpressure roller 5a in the below of main roller 4,5b, 5c, 5d, strainer 2 places between the two, and the frictional force that causes heavy caliber main roller 4 and hyperpressure roller to stress on 2 generations of strainer drives strainer 2 and advances.During work, after mud inlet enters conditioning groove 1, can add earlier after high-molecular coagulant mixed stirring referring to Fig. 4 mud, advance with transmission strainer 2, after a gravity dehydration portion 3 dehydrations, through one group of hyperpressure roller 5a, 5b, 5c, the squeezing extrusion of 5d forces mud to discharge large quantity of moisture, and last sludge pressing is become dried and flat, the sludge cake that moisture content is low, so that bury, processing such as incineration or curing, and discharge from the exit position.(referring to Fig. 3)

Referring to Fig. 2: power source of the present utility model impels heavy caliber main roller 4 and hyperpressure roller 5a by CD-ROM drive motor 7 and chain 8,5b, 5c, 5d stresses on 2 frictional force that produced drives of strainer strainer 2 and advances, referring to Fig. 6, the power source in the prior art impels small-bore driving rolls 6 and 2 frictional force that produced drives of strainer strainer 2 to advance by CD-ROM drive motor 7 and chain 8.The two is compared, and big main roller 4 drives and will come smooth and easyly than smaller naturally driving rolls 6 drives of trundle than big roller, and speed is fast, is difficult for skidding, and stagnation or motionless situation take place, so the utility model has more preferable dewatering.Separate for the high dehydration property that guarantees strainer 2 and not produce choking phenomenon, between advancing, its strainer 2 is provided with the high pressure washing sprinkler head on the position of a fixed point, to clean transmission strainer 2, the water after water that it took off and the washing, in the inflow water-collecting tray, enter the whole circulation treatment system again.

The utility model on the structure than the traditional sludge dewaterer many one group of hyperpressure roller devices, so can increase the moisture content of squeeze pressure, made sludge cake moisture content is reduced to about 75% with the reduction sludge cake.
