Abstract
The utility model discloses a plate and frame filter press, which comprises a filter press main body. A filter plate and a filter frame are arranged in the filter press main body. A material channel is connected onto the filter press main body. A high-pressure air channel is connected to the inlet end of the material channel. On the basis of the plate and frame filter press in the prior art, the plate and frame filter press disclosed by the utility model is improved. Because the high-pressure air channel is connected to the inlet end of the material channel, a filter mud cake on the filter plate is blown through high-pressure air so that effective liquid on the filter mud cake enters a liquid storage container below the filter press main body. The mud cake filtered by the filter press has higher solid content and good separation effect. Furthermore, the mud cake is blown by high-pressure air, the thickness of the mud cake is rapidly increased; the filter resistance is increased; the mud cake can be intercepted by a filter cloth; and the separation efficiency is higher.
Description
Technical field
The utility model relates to a kind of spray drying device technical field, relates in particular to and is used as the auxiliary instrument that cleans in a kind of spray drying tower.
Background technology
Plate and frame filter press constitutes one group of filter chamber by filter plate and the filter frame alternately arranged.There is groove on the surface of filter plate, and its protrusion position is in order to support filter cloth.On the corner of filter frame and filter plate through hole is arranged, the assembling back constitutes complete passage, can feed suspension, washings and draw filtrating.Plate, each jug rest of frame both sides are on crossbeam, by hold down gag pressure strip, frame.Filter cloth between plate, the frame plays gasket seal.By charging pump suspension is pressed into filter chamber, on filter cloth, forms filter residue, until being full of filter chamber.Filtrating pass filter cloth and along filter plate trench flow to sheet frame corner passage, concentrate to discharge.Filtration finishes, and can feed to clean to wash the water washing filter residue.After the washing, also feed compressed air sometimes, remove remaining cleaning solution.Open filter press removal filter residue subsequently, clean filter cloth, pressure strip, frame begin next operation cycle again.
Mainly there is following problem in the plate and frame filter press of prior art: when material is squeezed in the filter through pump through material channel; Though be to compress with modes such as manual spiral, electric screw or hydraulic pressure through plate and frame; Effectively liquid flows into the liquid storage container under the filter, and the mud cake high humidity that is filtered also exists a lot of effectively liquid not to be filtered out; The solid content of the mud cake after filter press filters is low, inferior separating effect.
The utility model content
The utility model is the shortcoming to above-mentioned existence, and a kind of plate and frame filter press structure is provided, and it is simple in structure, and the good separating effect of material, liquid are easy to effectively filtered out, and improve its operating efficiency.
The technical scheme that technical problem adopted that the utility model solves is:
A kind of plate and frame filter press comprises the filter main body, is provided with filter plate and filter frame in the filter main body, is connected with material channel on the filter main body, it is characterized in that being connected with the pressure-air passage at the material channel entrance point.Material gets into the filter press main body with pump through material channel, and the effect of pressure-air is produced by boasting material from filter plate, come out the fluid separation applications of material effectively.
Usually the front end of pressure-air passage is connected with air compressor machine.Air compressor machine is after material gets into filter plate pressure-air to be provided.
The beneficial effect of the utility model is: the utility model improves on the plate and frame filter press of prior art; Be connected with the pressure-air passage at the material channel entrance point; With pressure-air the filtration mud cake on the filter plate is dried up; Make the effective liquid that filters on the mud cake get into the liquid storage container under the filter main body, the mud cake after filter press filters has higher solid content and good separating effect.In addition, when pressure-air dried up mud cake, cake thickness increased very soon, and filtration resistance strengthens, and mud cake will be held back by filter cloth, and separative efficiency is higher.
Description of drawings
Below in conjunction with accompanying drawing and embodiment utility model is further specified.
Fig. 1 is the structural representation of the utility model embodiment.
Among the figure: 1, filter main body 2, material channel 3, pressure-air passage 4, air compressor machine.
The specific embodiment
In Fig. 1, a kind of plate and frame filter press comprises filter main body 1, is provided with filter plate and filter frame in the filter main body 1, is connected with material channel 2 on the filter main body 1, is connected with pressure-air passage 3 at material channel 2 entrance points.Material gets into the filter press main body with pump through material channel; The front end of pressure-air passage is connected with air compressor machine 4; Air compressor machine 4 provides pressure-air for material after getting into filter plate, and the effect of pressure-air is produced by boasting material from filter plate, come out the fluid separation applications of material effectively.
The structure of filter main body 1 is a prior art; Filter plate and filter frame by alternately arranging constitute one group of filter chamber, and plate and frame compress with hydraulic way, after hydraulic pressure compresses; The liquid that filters out pass filter cloth and along filter plate trench flow to sheet frame corner passage, concentrate to be discharged to the liquid storage container under the filter main body.The utility model improves on the plate and frame filter press of prior art; Be connected with pressure-air passage 3 at material channel 2 entrance points; With pressure-air the filtration mud cake on the filter plate is dried up; Make the effective liquid that filters on the mud cake get into the liquid storage container under the filter main body 1, the mud cake after filter press filters has higher solid content and good separating effect.In addition, when pressure-air dried up mud cake, cake thickness increased very soon, and filtration resistance strengthens, and mud cake will be held back by filter cloth, and separative efficiency is higher.
Claims (2)
