本发明属于污泥处理设备技术领域， 具体涉及一种污泥脱水机。 在本发明之前的现有技术  The invention belongs to the technical field of sludge treatment equipment, and particularly relates to a sludge dewatering machine. Prior art prior to the present invention
本发明所指的污泥包括城市污水污泥、河道及湖泊清淤污泥， 此类污泥的 主要特性一般是有机物含量高、 容易腐化发臭、 颗粒较细、 比重较小、 含水 率高、 呈胶状结构的亲水性物质。一般要处理的污泥， 其含水率在 90 %以上， 根据以上特点， 必须用脱水能力强的机械对其进行脱水。  The sludge referred to in the present invention includes urban sewage sludge, river channel and lake dredging sludge. The main characteristics of such sludge are generally high organic content, easy to decay and odor, finer particles, smaller specific gravity and high water content. , a hydrophilic substance in a gel structure. Generally, the sludge to be treated has a water content of more than 90%. According to the above characteristics, it must be dewatered by a machine with strong dehydration ability.
目前主要用于污泥脱水的装置是板框压滤机。板框压滤机属于间歇式的脱 水装置， 其一次能够处理大量的湿污泥， 并且能够承受很大的液压， 因此脱 水效果好。 用板框压滤机压滤后的污泥一般含水率在 60 %， 而此污泥则被压 滤成很大的滤饼并常常粘在滤板的滤布上难以自动脱落。 通常的处理方法是 先将这些附着在滤布上的块状污泥滤饼用手工的方法敲落到污泥槽， 然后进 行破碎， 再送去下一个工序。 这种污泥滤饼手工卸载的方法， 需要消耗一定 的人力， 且处理效率不高， 容易造成工厂空间和资源的浪费。 发明目的  At present, the main equipment used for sludge dewatering is a plate and frame filter press. The plate and frame filter press is a batch type dewatering device that can handle a large amount of wet sludge at a time and can withstand a large hydraulic pressure, so the dewatering effect is good. The sludge after filtration by the plate and frame filter press generally has a water content of 60%, and the sludge is crushed into a large filter cake and often sticks to the filter cloth of the filter plate to be easily peeled off. The usual treatment method is to first knock the bulk sludge filter cake attached to the filter cloth to the sludge tank by hand, then crush it, and then send it to the next step. The manual unloading method of the sludge filter cake requires a certain amount of manpower, and the treatment efficiency is not high, which is easy to waste the plant space and resources. Purpose of the invention
为了克服现有技术的不足， 本发明的目的在于提供一种结构简单， 制造 成本低， 脱水率高， 自动化高的鼓气式和板框压滤污泥脱水机。 本发明所采用的技术方案  In order to overcome the deficiencies of the prior art, the object of the present invention is to provide a blower type and plate and frame filter press sludge dewatering machine which is simple in structure, low in manufacturing cost, high in dehydration rate, and high in automation. Technical solution adopted by the invention
本发明是这样实现的： 一种鼓气式和板框压滤污泥脱水机， 由板框 压滤机和鼓气机组成， 所述板框压滤机和鼓气机之间连接总管道， 所述总管 道上设置有若干个电动控制阀。  The invention is realized as follows: a drum-type and plate-frame filter press sludge dewatering machine, which is composed of a plate and frame filter press and an air blower, and the main pipe is connected between the plate frame filter press and the air blower. The plurality of electric control valves are disposed on the main pipeline.
所述板框压滤机与总管道之间连接有阀门。  A valve is connected between the plate frame filter press and the main pipe.
所述鼓气机与总管道之间连接有阀门。 本发明用鼓气机对总管道进行鼓气， 在瞬间很大的气压作用下， 附着在 滤板上的污泥滤饼被从滤板与滤布之间吹出的风吹下， 从而实现了污泥滤饼 从板框压滤机上自动卸载的过程， 提高了加工效率， 而且成本低。 附图说明 A valve is connected between the air blower and the main pipe. The present invention uses an air blower to blow the main pipe, and under a large atmospheric pressure, the sludge filter cake attached to the filter plate is blown off by the wind blown from the filter plate and the filter cloth, thereby realizing The process of automatically unloading the sludge filter cake from the plate and frame filter press improves the processing efficiency and the cost is low.
