Abstract
The utility model discloses a heat conducting oil paddle shaft for a sludge dryer, belonging to the technical field of drying equipment. The paddle shaft comprises a hollow paddle shaft, each end of which is provided with a jacketed tube, a plurality of paddles which are communicated with the inner cavity of the paddle shaft are fixedly arranged outside the paddle shaft at equal intervals, an oil transmission pipe is arranged in the paddle shaft, two ends of the oil transmission pipe pass through an reinforced plate and are welded to the reinforced plate, and the reinforced plate is welded to the inner wall of the paddle shaft. The heat conducting oil paddle shaft has the advantages of strong practicality, superior performance, reasonable design, safety and reliability and is convenient to operate and maintain; mainly based on high-humidity materials and especially aiming at various materials in a mud state at high temperature, the heat conducting oil paddle shaft has the advantages of high drying speed and low energy consumption, can dry materials with water content higher than 80% into finished products in one step, and is applicable to high-humidity materials, such as all kinds of active sludge, sewage sludge, papermaking sludge, all kinds of groove slag, and the like; and in addition, heat conducting oil is used as a heat conducting medium, and the structure configuration in the paddle shaft is changed, therefore, heat conducting efficiency is greatly improved.
Description
Technical field
The utility model discloses a kind of thermal oil sludge drier blade spindle, belong to the drying plant technical field.
Background technology
Along with the development in Chinese society economy and city, the generation of municipal effluent is in continuous increase.In recent years, country all actively supported on policy and financial resources, had built large quantities of municipal sewage plants, and to keep water surrounding, the anti-pollution of harnessing the river promotes the Sustainable development of national economy and ecotope, and the municipal effluent problem progressively is eased.Yet the city sewage and sludge treatment and disposal is still a global technical barrier.Mishandlingly will cause serious secondary pollution.The innocuity treatment problem of mud is increasingly serious.
At present, the common method that adopts of sewage work is a sludge dewatering outward transport landfill disposal.Such processing mode not only pollutes but also takies a large amount of soils to environment.And, contain elements such as a large amount of organic substances and nitrogen, phosphorus, potassium in the mud.If can also make agrochemical, promote the development utilization of recycling economy through effective processing.It is low that existing sludge drier exists dryness factor, and uneven drying is even, deficiencies such as mud caking seize.
The utility model content
The utility model is at the deficiencies in the prior art, and purpose is to propose a kind of simple for structure, heat conductivity height, uniform drying, the thermal oil sludge drier blade spindle that use properties is good, it is low to have overcome the dryness factor that exists in the prior art, and uneven drying is even, the mud defectives such as seize of luming easily.
For realizing the utility model purpose, by the following technical solutions: a kind of thermal oil sludge drier blade spindle, it is characterized in that: comprise that two ends have the groomed oar rachis of jacket pipe, blade spindle is even outward apart from being installed with the some blades that communicate with its inner chamber at interval, be provided with transition pipeline in the blade spindle, weld by stiffening plate and with stiffening plate at the two ends of transition pipeline, the inwall welding of stiffening plate and blade spindle.
The utility model further is set to:
The shape of described blade is wedge shape covering of the fan structure.
Described blade and blade spindle are by automatic submerged-arc welding machine seal welding.
Have cavity in the described blade, and be connected in the inner chamber of this cavity and blade spindle.
The number of the transition pipeline in the described single paddle axle is two, arranges with the form of central horizontal.
The utility model is practical, and is easy to operate, and superior performance is reasonable in design, and is safe and reliable, easy to maintenance; Mainly, be mud shape material at various high temperature blankings specially based on high moisture material.Have and dry rapid, characteristic of low energy consumption.It can be disposable with the dry materials of 80% water content to finished product, be applicable to various active sludge, downflow sludge, high moisture materials such as paper mill sludge and various groove slags.It is heat-conducting medium that the utility model adopts thermal oil, has changed the blade spindle inner structure and has been equipped with, and has improved heat exchange efficiency greatly.
Below in conjunction with description of drawings and specific embodiment the utility model is elaborated.
Description of drawings
Fig. 1 is an one-piece construction synoptic diagram of the present utility model.
Embodiment
As shown in Figure 1, a kind of thermal oil sludge drier blade spindle, comprise that two ends have the groomed oar rachis 2 of jacket pipe 1, this jacket pipe 1 is installed on the bearing support of sludge drier tank ends, jacket pipe 1 closely cooperates and is installed in the two ends of blade spindle, and the end face that links to each other with blade spindle is careful welding.Blade spindle 2 is outer even apart from being installed with the some blades 3 that communicate with its inner chamber at interval, be provided with transition pipeline 4 in the blade spindle 2, the two ends of transition pipeline 4 are by stiffening plate 5, be that stiffening plate 5 offers the hole that can supply transition pipeline 4 to pass, transition pipeline 4 closely cooperates with stiffening plate 5 and mating surface adopts electric welding carefully to weld, and stiffening plate 5 also adopts careful welding with the inwall of blade spindle 2.Wherein, the shape of blade 3 is wedge shape covering of the fan structure.Blade 3 carefully welds by the automatic submerged-arc welding machine with blade spindle 2.Have cavity 31 in the blade 3, and be connected in the inner chamber 21 of this cavity 31 and blade spindle 2.The number of the transition pipeline 4 in the described single paddle axle 2 is two, arranges with the form of central horizontal.Bring maximum heat interchanging area to blade spindle, improve drying sludge efficient, and make heat conduction even, uniform drying.Use this structure heat conduction blade spindle more than 2 groups or 2 groups in the sludge drier complete machine, the blade between the adjacent set heat conduction blade spindle is for being staggered.
