Description
Technical field
The utility model belongs to the solid-liquid separation technique field, relates in particular to a kind of plate and frame filter press that is widely used in industries such as food, chemical industry.
Background technology
In industries such as the food that uses plate and frame filter press, chemical industry, traditional solid-liquid separation method is stiff end one endfeed, the wash water from filter, the shortcoming that the method exists is: material is skewness between filter plate, feed time is longer, the squeezing time is longer, and through after the long period press filtration, the filter cake moulding is hard, greatly reduce the service efficiency of filter press, improved production cost indirectly; Back 2/3rds filter cakes of terminal even whole the filter of charging can not be by abundant wash water, causes that filter cake moisture content is higher, fluctuation is bigger, and follow-up integrated treatment energy consumption is higher; The feed liquid remaining quantity is higher and inhomogeneous in the filter cake, has reduced the feed liquid rate of recovery, thereby has reduced the material yield.At the problem of above existence, equipment or the technology of being badly in need of a kind of reasonable optimizing of searching are improved.
Summary of the invention
The purpose of this utility model is, overcomes the deficiencies in the prior art, and a kind of plate and frame filter press is provided, and this technical scheme adopts the press filtration method of two endfeeds, wash water.The stiff end of sheet frame filter is connected to charging aperture, and movable end is connected to the continuous charging aperture that is flexible coupling, and the middle filter plate place of filter utilizes blind plate or utilizes channel-less filter cloth to cut off, and material can be from the two ends throat-fed and the wash water of filter.The utilization rate of filter press is improved, can realize the filter cake between whole all filter plates of filter is carried out wash water, improve the feed liquid rate of recovery and reduce filter cake moisture content.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of plate and frame filter press, comprise movable end, stiff end, feed pipe and be positioned at valve on the feed pipe, described feed pipe comprises feed pipe I and feed pipe II, feed pipe I is connected with movable end, and feed pipe II is connected with stiff end.
Be fixedly connected with blind plate between middle part two filter plates of plate and frame filter press described in the utility model.Blind plate is separated into two independent sectors to filter press, and blind plate can be with filter plate and filter frame motion, and blind plate is fixedlyed connected with filter plate.
Material enters simultaneously from feed pipe I and feed pipe II and carries out Separation of Solid and Liquid in the plate and frame filter press, after press filtration is finished, filter cake is washed and reclaims feed liquid from feed pipe I and feed pipe II water flowing.Press filtration after the charging simultaneously of the two ends of plate and frame filter press, under same pressure condition, filtration, wash water, squeezing time obviously shorten, and the filter press service efficiency improves.
Material enters from feed pipe I or feed pipe II and carries out Separation of Solid and Liquid in the plate and frame filter press, after press filtration is finished, filter cake is washed and reclaims feed liquid from feed pipe I or feed pipe II water flowing.Owing to be positioned at the blind plate in the middle of the plate and frame filter press, make press filtration be separated into two parts, can use simultaneously, also can only use an end wherein separately, also can be used alternatingly two ends, this end press filtration, the other end cleans filter cake, begins to clean filter cake after this end press filtration is finished, and the other end begins press filtration again, so just can realize continuously uninterrupted press filtration, when having improved the press filtration quality, also improve the operating efficiency of filter press.
Application in citric acid fermentation mash Separation of Solid and Liquid
Utilize pump to enter off-the-shelf plate and frame filter press from the feed pipe at plate and frame filter press two ends simultaneously the karusen that stops the fermentation heat sterilization, feed pressure is controlled at 0.45MPa and carries out Separation of Solid and Liquid, continue charging after 3 hours, stop feed pump, the feed pipe of high-temperature-hot-water by two ends entered the sheet frame filter to carry out wash water to filter cake and reclaims dilture acid, wash water 15 minutes, every leaf filter plate all has hot water to flow out, air blowing 10min, detect the residual acid of filter cake≤0.8%, than equal charging, one endfeed mode time of filter pressing of wash water condition on average shortens 1h, the residual acid of filter cake is on average low more than 50%, and filter cake moisture is on average low more than 10%.
Application in the liquefier sugar slag press filtration that with the corn is raw material
The corn liquefaction liquid pump that liquefaction is qualified is to plate and frame filter press, liquefier enters filter from the two ends feed pipe of filter respectively, feed pressure 0.45MPa, continue charging 3 hours, stop feed pump, high-temperature-hot-water is entered plate and frame filter press by the two ends feed pipe filter cake is carried out wash water recovery residual sugar, heat hydraulic pressure 0.55MPa, every leaf filter plate all has hot water to flow out, wash water 10 minutes, air blowing 10min, filter cake butt starch average content≤30% is than equal charging, the time of filter pressing of one endfeed mode of wash water condition on average shortens 1h, the sugar pulp water divides average low more than 10%, sugar slag content of starch is on average low more than 15%.
The beneficial effects of the utility model are: a kind of plate and frame filter press, comprise movable end, stiff end, feed pipe and be positioned at valve on the feed pipe, described feed pipe comprises feed pipe I and feed pipe II, and feed pipe I is connected with movable end, and feed pipe II is connected with stiff end.Under same pressure condition, filtration, wash water, squeezing time obviously shorten, and the filter press service efficiency improves; The filter cake wash water is more abundant, feed liquid rate of recovery height; Filter cake moisture content is low and even, and follow-up comprehensive utilization energy consumption is low; Good energy-conserving effect; Flow process is succinct, easy operating.
