簡介

螺旋擠壓脫水機(Screw extrusion dehydrator)是一種用於凝聚、脫水的主要設備。主要由螺杆、圓筒形籠式外殼和錐體三部分組成,由撓性聯軸節將螺杆軸與減速器的輸出軸連接起來。

Brief Introduction

 

Screw extruder is a main equipment used for coagulation and dehydration. It is mainly composed of screw, cylindrical cage shell and cone. The screw shaft is connected with the output shaft of reducer by flexible coupling.

主機結構及各部件的作用

脫水機主要由螺杆、圓筒形籠式外殼和錐體三部分組成,由撓性聯軸節將螺杆軸與減速器的輸出軸連接起來。

1.螺杆

由節螺紋和軸環交替地套在螺杆軸上組成。每節螺紋和軸環分別用鍵固定在螺杆軸上。螺紋除第1節(進料區)為三圈等距連續螺紋外,其餘各節均為單圈開放式,各節螺距均不相同,由低壓側到高壓側逐漸縮小,輪轂直徑則逐漸增大以增加壓力,藉以擠出橡膠中的水分。

2.圓筒形能式外殼

由固定在骨架上的籠條所組成的蓖子板構成。蓖子板分8段,每段長度不等。圓筒內徑為18英寸,在垂直中心線上分成兩半以螺栓緊固,以便於清洗和維修時拆卸。組成蓖子板的籠條之間被彈簧片隔開形成縱縫,以使水分流出。在圓筒內上下兩側的骨架上設有刮刀,與螺杆上的軸環位置相對應,其作用是阻止橡膠隨螺杆旋轉,強製橡膠改變推進方向和位置,並使之形成疏鬆多孔狀,以利於幹燥。圓筒外部設有四個供加熱或冷卻用的夾套,可根據工藝要求分區控製機內的溫度。在丁苯橡膠生產中,隻是在開車前通蒸汽預熱機體時才使用。

3.錐體

這是設在出料區的錐形圓筒,可以前後移動以便與固定在螺杆軸上的環相配合。錐體前後移動是由調速電機通過四個千斤頂組成的齒輪帶動的同時也設有手動調節機構。通過錐體的前後移動來增減出口銳孔的麵積,以改變機內的壓力,從而調節橡膠的脫水率。橡膠自錐體銳孔擠出後,被安裝在螺杆軸上的刀具切成小塊。由於橡膠在機內受到機被的剪力和被壓縮而使溫度升高,故在通過錐體銳孔時橡膠中的水分即行閃蒸,從而使橡膠呈疏鬆多孔狀。

Main Structure and Function of Each Component
The dehydrator is mainly composed of screw, cylindrical cage shell and cone. The screw shaft is connected with the output shaft of the reducer by flexible coupling.

1. screw

The screw is composed of a screw thread and a shaft ring alternately sleeved on the screw shaft. Each thread and shaft ring are fixed on the screw shaft with keys. Except for the first section (feeding area) which is three-circle continuous threads with equal distance, the other sections are single-circle open type. The pitches of each section are different. The pitches of each section are gradually reduced from the low pressure side to the high pressure side, while the diameter of the hub is gradually increased to increase the pressure so as to extrude the moisture in rubber.

2. cylindrical energy shell

It is made of castor plates made of cage bars fixed on the skeleton. The castor plate is divided into 8 sections with different lengths. The inner diameter of the cylinder is 18 inches and is bolted in two halves along the vertical center line for easy removal during cleaning and maintenance. The cage bar consisting of castor plates is separated by springs to form longitudinal joints to cause water to flow out. A scraper is arranged on the skeleton of the upper and lower sides of the cylinder, which corresponds to the position of the axle ring on the screw. Its function is to prevent the rubber from rotating with the screw, force the rubber to change the direction and position of propulsion, and make it porous, so as to facilitate drying. There are four jackets outside the cylinder for heating or cooling, which can control the temperature in the machine according to the process requirements. In the production of styrene butadiene rubber, it is used only when steam is preheated before starting up the machine.

3. cone

This is a conical cylinder located in the discharge area, which can be moved back and forth to match the ring fixed on the screw shaft. The front and back movement of the cone is driven by the gears composed of four jacks of the speed governing motor, and at the same time there is a manual adjusting mechanism. By moving the cone back and forth, the area of the sharp hole at the outlet is increased and reduced, so as to change the pressure in the machine, thus adjusting the dehydration rate of rubber. After extrusion of the rubber cone, the cutter is cut into small pieces on the screw shaft. Because rubber is heated by shearing force and compression inside the machine, water in the rubber flash evaporated when passing through the sharp hole of the cone, which makes the rubber porous.

 

工作原理

1、旋轉過濾:汙泥經絮凝劑劑絮凝後,形成一定強度的絮團,含有大量自由水的固液混合物經立式反應器溢流口進入旋轉過濾機,汙泥在螺旋軸軸葉片的推動下向前運動,由於重力作用進行自由脫水,滾筒與螺旋轉向相反,使汙泥在滾筒內不斷翻滾,把絮團內部自由水不斷的濾出,濃縮後的汙泥經螺旋葉片推送中出料口,進入下一級脫水工序。

2、螺旋擠壓:預脫水完的汙泥經進料鬥進入螺旋擠壓機後,汙泥在錐度螺旋軸和變徑螺旋的作用下,使物液產生體積上壓縮,從而使料液中的水分通過孔狀濾筒迅速被分離出去,而固體物在不斷壓縮的作用下含水率逐漸下降而成為百家乐下载所需要的濾餅,最後在螺旋的輸送作用下排出機外  。

Working principle

 

1. Rotary filtration: sludge is flocculated by flocculant to form a certain strength flocculent. Solid-liquid mixture containing a large amount of free water enters the rotary filter through the overflow port of vertical reactor. Sludge moves forward under the impetus of the helical shaft blade. Because of gravity, it is dewatered freely, and the drum turns opposite to the helix. Sludge rolls continuously in the drum, and the free water in the floc is filtered out continuously. The concentrated sludge is pushed to the outlet through the spiral blade and enters the next dewatering process.

2. Screw extrusion: After the pre-dewatered sludge enters the screw extruder through the feed hopper, the sludge is compressed in volume under the action of taper helix axis and diameter-changing helix, so that the moisture in the sludge is quickly separated through the porous filter, while the moisture content of solid gradually decreases under the action of constant compression to become the filter cake we need, and finally discharge it out under the action of screw transportation.

 

用途

如酒糟、果渣、藥渣、木薯渣等的脫水,大大減輕幹燥機的負擔,產量大幅度提高,能耗大幅度降低,是高濕物料幹燥前必不可少的處理設備,經過脫水後的物料可以直接進入幹燥設備。

Purpose

 

For example, the dehydration of distiller's grains, fruit dregs, medicine dregs and cassava dregs can greatly reduce the burden of dryer, greatly increase the output and reduce the energy consumption. It is an indispensable treatment equipment before drying of high-humidity materials. The dehydrated materials can directly enter the drying equipment.
