Description

Solid waste is pyrolyzed anti-coking highly effective sludge drying heater

Technical field

It the utility model is related to technical field of sludge treatment, and in particular to a kind of solid waste is pyrolyzed anti-coking highly effective sludge drying Heater.

Background technology

Because the sludge volume discharged from sewage plant is huge, loose condition (of surface) is presented, moisture content is high.In order to realize subtracting for sludge Quantify, innoxious and stabilisation, it is often necessary to dewater treatment, namely the drying process of sludge.Dried sludge can be used for Landfill, compost, burning and heat energy utilization etc., no matter which kind of is utilized, and drying sludge is the important first step.

In sludge drying processing, mechanical dehydration is only capable of removing Free water and portion gap water, capillary water and internal junction It is unworkable that Heshui is removed using mechanical means, and need to use the measure such as high-temperature heating and freezing.

To reduce deep dehydration cost, now more is that applied chemistry conditioning combines plate and frame filter press technology progress depth Dehydration.Although cost is relatively low, there is also it is more the problem of.The increasing of the weight of sludge to a certain extent after addition conditioner Add, actually and be not implemented sludge minimizing.

At present, the general trend of external sewage sludge harmlessness disposing is：Sludge digestion technology large-area applications, Sludge landfill quilt Further forbid, sludge incineration will be fewer and fewer, and the heat drying for the purpose of land use is increasingly becoming Main Means.And how The heat loss during drying sludge is reduced, reduction, which is consumed energy and improves dry efficiency, is undoubtedly an important problem.

Utility model content

In place of overcoming above shortcomings in the prior art, the purpose of this utility model is to provide a kind of solid waste It is pyrolyzed anti-coking highly effective sludge drying heater.

The utility model is achieved through the following technical solutions：Solid waste is pyrolyzed anti-coking highly effective sludge drying heater, including Pipeline, the pipe ends side are provided with feed nozzle and discharging gate, are provided with rotatable rotating shaft inside the pipeline, described turn Axle both ends are fixed on support by bearing, wherein an end bearing is connected by shaft coupling with reducing motor, the rotating shaft is along axle Painting apply flitch and scraper are respectively fixed with to provided with a plurality of staggered paddle blades and chopper, the paddle blade both ends.

The utility model also includes to pipe heating device.

Further, paddle blade described in the utility model is curved surface.

The utility model compared with prior art, has advantages below and beneficial effect：Due to provided with above structure, this reality Heated with new by pipeline, the moisture content of sludge can be substantially reduced；Simultaneously rotation process by paddle blade, painting apply flitch, split Knife, scraper are handled different conditions sludge, efficiently realize the minimizing of sludge, can very well by sludge drying into Type, it greatly reducing the waste of energy.

Embodiment

Embodiment of the present utility model is described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning Same or similar element is represented to same or similar label eventually or there is the element of same or like function.Below by ginseng The embodiment for examining accompanying drawing description is exemplary, is only used for explaining the utility model, and it is not intended that to of the present utility model Limitation.

In description of the present utility model, it is to be understood that term " " center ", " longitudinal direction ", " transverse direction ", " on ", " under ", The orientation or position relationship of the instruction such as "front", "rear", "left", "right", " vertical ", " level ", " top ", " bottom ", " interior ", " outer " are Based on orientation shown in the drawings or position relationship, it is for only for ease of description the utility model and simplifies description, rather than instruction Or imply that signified device or element must have specific orientation, with specific azimuth configuration and operation, therefore be not understood that For to limitation of the present utility model.In description of the present utility model, unless otherwise indicated, " multiple " are meant that two or two More than individual.

, it is necessary to which explanation, unless otherwise clearly defined and limited, term " are pacified in description of the present utility model Dress ", " connected ", " connection " should be interpreted broadly, for example, it may be fixedly connected or be detachably connected, or integratedly Connection；Can be mechanical connection or electrical connection；Can also be joined directly together or indirect by intermediary It is connected, can is the connection of two element internals.For the ordinary skill in the art, on being understood with concrete condition State concrete meaning of the term in the utility model.

With reference to as shown in Figure 1 to Figure 3, solid waste is pyrolyzed anti-coking highly effective sludge drying heater, including pipeline 1, the pipe 1 liang of road end side surface is provided with feed nozzle 2 and discharging gate 3, and the inside of pipeline 1 is provided with rotatable rotating shaft 4,4 liang of the rotating shaft End is fixed on support 5 by bearing, wherein an end bearing is connected by shaft coupling 6 with reducing motor 7, the rotating shaft 4 is along axle To provided with a plurality of staggered paddle blades 8 and chopper 9, paddle blade 8 is curved surface, and the both ends of paddle blade 8 are respectively fixed with Painting apply flitch 10 and scraper 11.

The utility model also includes to pipe heating device, and heater is mainly used in heating pipeline outer wall, makes sludge It is heated into sludge bulking.

Utility model works principle：First by sludge from feed nozzle 2 enter pipeline 1 in from painting apply flitch 10 be pushed into sludge to The direction of discharging gate 3 is advanced, and heater heats to the outer wall of pipeline 1, temperature is heated between 600-700 degree, now before sludge During entering, because painting apply flitch 10 and the gap of pipeline 1 are smaller, temperature is high, and sludge is easily sticked on the inwall of pipeline 1, Ran Houtong Cross scraper 11 to scrape the dewatered sludge on inwall, then sludge is rived by chopper 9, sludge continues to advance to discharging gate direction, most Sludge is fabricated to dry block afterwards, then is discharged from discharging gate.

While there has been shown and described that embodiment of the present utility model, it will be understood by those skilled in the art that： In the case where not departing from principle and objective of the present utility model a variety of change, modification, replacement and modification can be carried out to these embodiments, The scope of the utility model is limited by claim and its equivalent.
