Description

High effective and energy saving liquid settling apparatus

The utility model belongs to sedimeter, specifically includes a kind of high-efficiency energy-saving liquid clarifier of a filter plate filtration system.

Current in food service industry, be used for liquid and beverage, beer, fruit juice, drinks etc. and clarify the device of removing impurity, having a kind of is to fill diatomite or cottonseed cake in a rectangle cylindrical container, with diatomite or cottonseed cake as filter medium, treat that supernatant liquid flows through from diatomite or cottonseed cake in container, solid content, impurity be separated and be trapped in diatomite or cottonseed cake in, liquid obtain the clarification.Because diatomite or cottonseed cake are as filter medium, its resistance is bigger, and after particularly solid content, impurity were trapped within diatomite or the cottonseed cake, resistance was just bigger.Therefore, this liquid clarifier generally requires with higher pump head pressure transmission feed liquid; Container must have enough length, causes that this clarifier structure is huge, energy consumption is high, production efficiency is low, simultaneously, after solid content, impurity accumulate to a certain degree, must all change diatomite or cottonseed cakes in diatomite or cottonseed cake, has improved running expense.

The purpose of this utility model just is to overcome above-mentioned the deficiencies in the prior art, a kind of structure that includes the high-efficiency energy-saving liquid clarifier of a filter plate filtration system is disclosed, be fit to food service industry liquid and beverage, beer, fruit juice, drinks etc. and clarify and remove the impurity operation and use, have characteristics such as simple in structure, that production efficiency is high, energy consumption is low, easy to use and running expense is low.

The utility model is a kind of high-efficiency energy-saving liquid clarifier, include a filter plate filtration system, the technical scheme that realizes the utility model purpose is: this filter plate filtration system is by filter plate, filter cloth, decide plate, moving plate and hydraulic jack are formed, be provided with filter cloth between the filter plate of at least two above filter plate composition filter plates, on every filter plate, be provided with a charging hole and an outage, all one side is provided with the charging groove that is communicated with charging hole on the both ends of the surface of every filter plate, another side is provided with the drainage groove that is communicated with outage, decide plate and moving plate and install two ends respectively in said filter plates, decide plate and be provided with corresponding with filter plate respectively a charging hole and an outage, feed pipe is fixedlyed connected with the charging hole of deciding plate, discharging tube is fixedlyed connected with the outage of deciding plate, and the hydraulic jack push rod contacts with moving plate.

A kind of high-efficiency energy-saving liquid clarifier of the utility model is to utilize the hydraulic jack push rod to promote moving plate, make the filter plates extruding of deciding between plate and the moving plate be one, the charging hole of each filter plate is connected to become feeding-passage, the outage of each filter plate is connected to become apocenosis passage, enter the charging groove that end face is provided with from each filter plate charging hole from the supernatant liquid for the treatment of of deciding that the plate charging hole sends into, under liquid conveying pressure, see through the filter cloth that is provided with between two filter plates, enter in the drainage groove that is provided with on the adjacent filter plate end face, conflux again to the filter plate outage, be the liquid of having clarified from deciding the discharge of plate outage at last.The utility model as filter element, as filter medium, according to the requirement of filtration operation treating capacity, can suitably be selected the appearance and size specification and the filter plates filter plate sheet number of filter plate, simple in structure, easy assembling with filter cloth with filter plate; Because feed liquid is to obtain to filter clarification by the filter cloth that is provided with between filter plate, thereby filtration resistance is less, selects the filter cloth of corresponding order number, both can rationally reduce filtration resistance, can adapt to the filtration requirement that has with feed liquid again, the feed liquid conveying energy consumption is reduced greatly, filter efficiency height, filter quality are good; Particularly, when holding back solid content on the filter cloth between filter plate and reach capacity state, only need to shut down filter cloth taken off to remove and hold back solid content, after rinsing well, filter cloth is reusable, and is both convenient, reduced running expense again.In sum, a kind of high-efficiency energy-saving liquid clarifier of the utility model has been realized the purpose of this utility model preferably.

Below in conjunction with accompanying drawing, the utility model and preferred embodiment thereof are described further.
