Abstract
The invention discloses a filter press. The filter press comprises a filter press body and an inlet pipe used for feeding finished-product slurry into the filter press body. The inlet pipe is provided with a heat exchanger used for cooling the finished-product slurry. According to the filter press, the service lifetimes of filter cloths and filter boards of the press filter are prolonged and energy is saved.
Description
Technical field
The present invention relates to a kind of filter press.
Technical background
At present, filter press is widely used in industrial production as a kind of solid-liquid separating equipment.High temperature, high pressure, wet environment etc. all can affect greatly filter press service life, directly have influence on enterprises production efficiency and economic benefit.
Filter press is directly used in separating high-temp solidliquid mixture and has following shortcoming:
One, fragile filter press filter board: higher temperature can cause filter cake and filter plate to cause sinter arch formation (" sinter " refers to the shell that mineral surrounding is formed by precipitation of salts) on contact point, filter cake peel resistance is increased, larger on the impact in service life of filter cloth and filter plate.Conventional nylon filtering cloth, as a kind of synthetic polyamide fiber, is hydrophilic material simultaneously, and under large resistance, reusing, wash, be dried can aggravation contraction.Easily cause filter cloth to produce distortion, make the lost of life.
Two, energy consumption increases: filter cloth shrinks and causes filter cake to crack, and then atmosphere is communicated with vacuum chamber, and air is inhaled into vacuum chamber and has reduced vacuum, affects dehydrating effect, has increased power consumption.
Summary of the invention
Technical problem to be solved by this invention is just to provide a kind of filter press that extends canvas press cloth filter plate service life and save the energy.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A filter press, comprises filter press body and carries finished product slurries to flow into the feed pipe of filter body, described feed pipe is provided with the heat exchanger that can make finished pulp liquid temp reduce.
Preferably, described heat exchanger comprises the inner heat exchanger body with cavity, described heat exchanger body lower end is provided with the finished product slurries entrance being connected with cavity, heat exchanger body upper end is provided with the finished product slurries outlet being connected with cavity, in described cavity, be provided with the some conduits that are interconnected, described conduit is provided with inflow can the cooling water inlet of cold water and the hot water outlet of outflow hot water.
Preferably, described feed pipe porch is provided with centrifugal pump.
Preferably, described filter press body below is provided with the conveyer that can transport filter cake.
The present invention adopts technique scheme, at filter press front end, increases heat exchanger, and finished product slurries reduce through heat exchange temperature, and sinter arch formation obviously weakens, and has reduced the resistance between filter cake and filter plate, and filter plate is played a protective role.The shrinkage phenomenon of nylon filtering cloth is played to certain inhibitory action simultaneously, increased the service life of filter cloth.The heat exchanger of flowing through reduces finished product slurry temperature, than high temperature slurries, to filter press, provides more excellent condition of work.Weaken the shrinkage phenomenon of filter cloth, strengthened press filtration effect, reduced energy resource consumption.The cooling water of heat exchanger of simultaneously flowing through is heated and can be used for other links and produce, and has improved the utilization rate of the energy.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described further:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of heat exchanger in the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is elaborated.
As depicted in figs. 1 and 2, the present invention includes filter press body 1 and carry finished product slurries to flow into the feed pipe 2 of filter body 1, described feed pipe 2 is provided with the heat exchanger 3 that can make finished pulp liquid temp reduce.Described heat exchanger 3 comprises the inner heat exchanger body 3a with cavity, described heat exchanger body 3a lower end is provided with the finished product slurries entrance 301 being connected with cavity, heat exchanger body 3a upper end is provided with the finished product slurries outlet 302 being connected with cavity, in described cavity, be provided with the some conduits that are interconnected 303, described conduit 303 is provided with inflow can the cooling water inlet 304 of cold water and the hot water outlet 305 of outflow hot water.Described feed pipe 2 porch are provided with centrifugal pump 6.Described filter press body 1 below is provided with the conveyer 8 that can transport filter cake.
Filter press body 1 lower end is provided with rewinding funnel 7, and filter cake deviates to fall into rewinding funnel from filter press body 1 lower end, and the upper conveyor that falls afterwards 8 is transported to depository, and transmission device 8 comprises conveyer belt and roller bearing, and roller bearing is connected with motor.On filter press body 1, be also provided with and support the fixedly bracing frame 9 of filter press body 1, support frame as described above 9 tops surround fixedly filter press body 1, and bracing frame 9 also comprises several legs, and described leg is positioned over ground.
Wherein finished product slurries are produced by reaction tank 4, several reaction tanks 4 are connecting conveying pipe road 5 and being connected as a single entity respectively, and valve can also be set on conveyance conduit 5, thereby controls the outflow of finished product slurries, conveyance conduit 5 is communicated with feed pipe 2, also can be connected in centrifugal pump 6 and be communicated with feed pipe 2.
When the present invention works, centrifugal pump is evacuated to finished product slurries in feed pipe 2, after finished product slurries, pass through finished product slurries entrance 301 inflow heat exchanger 3 inner chambers, because conduit 303 flows into cold water by cooling water inlet 304, finished product slurries will be cooled, after being heated, cold water in conduit 303 flows out by hot water outlet 305, thereby realize circulating cooling finished product slurries, finished product slurries after being cooled flow into filter press body 1 and carry out press filtration, have extended the service life of canvas press cloth filter plate and have saved the energy.
Just preferred embodiment of the present invention is described above, but can not be interpreted as it is limitations on claims.The present invention is not only confined to above embodiment, and its concrete structure allows to change, and those skilled in the art can make according to the present invention various changes and distortion, only otherwise depart from spirit of the present invention, all belongs to the defined scope of claims of the present invention.
