在餐厨垃圾处理和地沟油处理工艺中，经常会用到固液分离的工序，目前比较常用的是螺旋压榨机或其它挤压式的脱水设备，但因物料成份复杂、固含物尺寸不一等原因，会有压榨效果不理想、筛网易破、处理量较小等问题。In the process of food waste treatment and waste oil treatment, the process of solid-liquid separation is often used. At present, screw presses or other extruding dehydration equipment are commonly used. However, due to the complexity of material components and the size of solids The first-class reasons include problems such as unsatisfactory pressing effect, easy breakage of the screen, and small processing capacity.
现常用的螺旋压榨机或其它挤压式的脱水设备通过体积压缩，使内部产生巨大压力，浆液透过筛网达到固液分离的目的，固物料中可能含有硬度较高的物质，在大压力下容易撑破筛网；螺旋压榨机在出渣口设置封头，如果有硬物刚好卡在出渣口，则容易使未压榨好的稀料从出渣口排出。The commonly used screw press or other extruding dehydration equipment generates huge pressure inside through volume compression, and the slurry passes through the screen to achieve the purpose of solid-liquid separation. The solid material may contain substances with high hardness. It is easy to break the screen; the screw press is equipped with a head at the slag outlet. If there is a hard object just stuck in the slag outlet, it is easy to discharge the unpressed thinner from the slag outlet.

根据本发明的脱水装置，利用主轴102转动产生的离心力进行脱水，在相对较小的压力环境下甩干物料实现固液分离的目的，对物料的耐受性好，筛网磨损和破损率相对较低；而且筛筒的筛孔不易堵，减少人工清理的工作量；具有可连续处理、处理能力大、效果稳定的优点。According to the dehydration device of the present invention, the centrifugal force generated by the rotation of the main shaft 102 is used for dehydration, and the material is dried under a relatively small pressure environment to achieve the purpose of solid-liquid separation. It is relatively low; and the sieve hole of the screen cylinder is not easy to be blocked, which reduces the workload of manual cleaning; it has the advantages of continuous processing, large processing capacity and stable effect.
其中，如图1所示，所述主轴102的进料端为空心轴，所述空心轴可构成所述进料管103。Wherein, as shown in FIG. 1 , the feed end of the main shaft 102 is a hollow shaft, and the hollow shaft can constitute the feed pipe 103 .
具体地，所述主轴102高速转动，其转速为300rpm-600rpm，进入所述筛筒101内的物料在所述主轴102的带动下转动，产生离心力而甩出浆液。Specifically, the main shaft 102 rotates at a high speed, and its rotational speed is 300rpm-600rpm. The material entering the sieve cylinder 101 is driven by the main shaft 102 to rotate, generating centrifugal force to throw out the slurry.
进一步地，所述筛筒101固定不转动。具体地，所述筛筒101 包括筛筒腔体1011和环绕所述筛筒腔体1011的筛网1012。物料由布料口104进入所述筛筒101的所述筛筒腔体1011内，然后在离心力的作用下甩出浆液。所述筛网1012的筛孔尺寸为1mm-5mm，小于筛孔尺寸的浆液透过筛网被甩出。Further, the screen cylinder 101 is fixed and does not rotate. Specifically, the sieve cylinder 101 includes a sieve cylinder cavity 1011 and a screen 1012 surrounding the sieve cylinder cavity 1011 . The material enters the sieve cavity 1011 of the sieve 101 through the material distribution port 104, and then the slurry is thrown out under the action of centrifugal force. The mesh size of the screen 1012 is 1mm-5mm, and the slurry smaller than the mesh size is thrown out through the mesh.
进一步地，所述脱水装置100还包括设置在所述筛筒101的出料端的出渣口106，用于排出脱水后的固渣。Further, the dehydration device 100 also includes a slag outlet 106 arranged at the discharge end of the screen drum 101 for discharging the dehydrated solid slag.
图2示出了主轴102的结构示意图。如图2所示，若干个所述布料口104均匀地所述在所述主轴102的侧壁上。所述布料口104的数量为2‐5个。若干个所述螺旋导流板105均匀地设置在所述主轴102 的侧壁上。所述螺旋导流板105的数量为2‐5个。在本发明中，所述布料口104和所述螺旋导流板105的数量相等，均为3个，且相邻的所述布料口104和所述螺旋导流板105相对位置关系相同。进一步地，所述螺旋导流板105与所述主轴102的倾斜角度为15o-20o，这样的小角度螺旋角有利于物料的搅动、排渣并刮净所述筛筒101的内壁。FIG. 2 shows a schematic structural view of the main shaft 102 . As shown in FIG. 2 , several distributing ports 104 are evenly described on the side wall of the main shaft 102 . The quantity of the cloth opening 104 is 2-5.

In the present invention, the number of the distribution openings 104 and the spiral deflectors 105 are the same, each being three, and the relative positions of the adjacent distribution openings 104 and the spiral deflectors 105 are the same. Further, the inclination angle between the spiral deflector 105 and the main shaft 102 is 15o-20o, such a small helix angle is conducive to the agitation of materials, slag discharge and scraping the inner wall of the screen drum 101 .
本发明的工作原理在于，物料从进料管103进入，在所述主轴 102产生的离心力的作用下通过主轴102上的布料口104进入筛筒 101的筛筒腔体1011内，主轴102高速转动，带动物料转动产生离心力，小于筛孔尺寸的浆液透过筛网1012被甩出，脱水后的固渣被螺旋导流板105推至出渣口106排出，从而实现固液分离的目的。本发明提供一种对成分复杂的高含固率物料进行脱水的装置，比如对餐厨垃圾货地沟油除去粗杂后的物料进行脱水处理，其结构紧凑，相较于螺旋压榨或其它挤压式压榨方式，具有连续进出料、处理能力大(可达几十吨每小时)、处理效果稳定的优点，出渣含水率可满足餐厨垃圾处理和地沟油处理工艺中的要求。The working principle of the present invention is that the material enters from the feed pipe 103, and enters the screen cylinder cavity 1011 of the screen cylinder 101 through the material distribution port 104 on the spindle 102 under the action of the centrifugal force generated by the spindle 102, and the spindle 102 rotates at a high speed , drives the material to rotate to generate centrifugal force, the slurry smaller than the mesh size is thrown out through the screen 1012, and the dehydrated solid slag is pushed to the slag outlet 106 by the spiral deflector 105 to be discharged, thereby achieving the purpose of solid-liquid separation. The invention provides a device for dehydrating materials with complex components and high solid content, such as dehydrating materials after removing rough impurities from kitchen waste and gutter oil. Its structure is compact, compared with screw pressing or other extrusion The press method has the advantages of continuous feeding and discharging, large processing capacity (up to dozens of tons per hour), and stable processing effect. The moisture content of the slag can meet the requirements of the kitchen waste treatment and waste oil treatment process.
综上所述，根据本发明的脱水装置，利用主轴转动产生的离心力进行脱水，在相对较小的压力环境下甩干物料实现固液分离的目的，对物料的耐受性好，筛网磨损和破损率相对较低；而且筛筒的筛孔不易堵，减少人工清理的工作量；具有可连续处理、处理能力大、效果稳定的优点。In summary, according to the dehydration device of the present invention, the centrifugal force generated by the rotation of the main shaft is used for dehydration, and the material is dried under a relatively small pressure environment to achieve the purpose of solid-liquid separation. And the breakage rate is relatively low; and the sieve hole of the screen cylinder is not easy to block, reducing the workload of manual cleaning; it has the advantages of continuous processing, large processing capacity and stable effect.
