The utility model discloses a discharging device for a pressure filter. The discharging device comprises a discharging channel, a sealed discharger and a material level mater, wherein the material level meter is mounted on the discharging channel; and the sealed discharger is arranged at a material outlet end of the discharging channel. The discharging device is simple in structure, low in fault rate, convenient to repair and good in sealing performance, and can be widely applied to the industries of energy, metallurgy, ceramics, building materials, chemical engineering and the like.
Description
Technical field
The utility model relates to a kind of pressing filter discharge device.
Background technology
At present, traditional pressing filter discharging method is to use the double gate valve alternation to realize sealing discharging, and the method is playing sealing function to the pressurization storehouse in the discharge smoothly, but the practical application apparatus structure is complicated, and fault rate is high, the maintenance trouble.
Summary of the invention
The utility model has remedied the deficiencies in the prior art, and a kind of pressing filter discharge device is provided, and this apparatus structure is simple, and failure rate is low is easy to maintenance, good seal performance.
The technical solution of the utility model is, it comprises discharging channel, and sealed discharger and level-sensing device, level-sensing device are installed on the discharging channel, and sealed discharger is arranged in the discharging channel discharge end.Sealed discharger and discharging channel are tightly connected.Sealed discharger comprises discharger storehouse shell and discharger, be provided with feeding mouth and discharging opening on the shell of discharger storehouse, the warehouse of discharger storehouse shell is sealed, and the discharging parts of discharger are arranged in the shell of discharger storehouse, and the discharging opening of discharger storehouse shell is provided with seal gate valve.Discharger can be drag conveyor or belt conveyor or first band conveyer.Be provided with peep hole on the shell of discharger storehouse, be provided with access door on the shell of discharger storehouse.Be provided with high-abrasive material in the discharging channel.The seal section inner surface of discharging channel is concave-convex.
In the pressing filter course of work, the sealing of discharging channel is that the accumulation by material realizes that the height of materials of controlling satisfies the requirement of material sealing discharging passage in the discharge process, does not need other SLD, and good seal performance.In pressing filter discharge process, level-sensing device detects height of materials, and program control system is controlled discharger according to height of materials, regulates discharging quantity, makes the height of materials in the discharging channel be controlled in the preset range or constant altitude, and discharge is reliable.
Compared with prior art, the utlity model has following beneficial effect:
1, of the present utility model simple in structure, failure rate is low, easy to maintenance;
2, good seal performance of the present utility model;
3, the utility model automaticity is high.

The specific embodiment
Embodiment 1, referring to figs. 1 through Fig. 3, a kind of specific embodiment of pressing filter discharge device is provided, discharge device 2 is installed in the below of pressing filter 1, discharging channel 3 is divided into material buffer section and material seal section, the material buffer section is the ab section, the material seal section is the following part of b, be covered with straight tube shape high-abrasive material 4 in the material buffer section, be covered with concave-convex high-abrasive material 5 in the material seal section, two passive nucleon stuff level switch 6 are arranged on the discharging channel 3, be installed in respectively a position and b position, sealed discharger 7 is installed in the discharge end of discharging channel 3, be provided with sealing rubber ring 13 between sealed discharger 7 and the discharging channel 3, sealed discharger 7 comprises discharger storehouse shell 8 and discharger 11, be provided with feeding mouth 9 and discharging opening 10 on the discharger storehouse shell 8, the warehouse of discharger storehouse shell 8 is sealed, be provided with peep hole 12 on the discharger storehouse shell 8, discharger 11 is double-deck drag conveyors, the motion track of material in discharger 11 is shown in dotted arrow among the figure, seal gate valve 14 is installed in discharging opening 10 places of discharger storehouse shell 8, and the steel wire device 15 of comminuting matter is installed in the pressing filter 1 main storehouse.When pressing filter 1 was started working, seal gate valve 14 was closed, the height of materials that passive nucleon stuff level switch 6 detects in the discharging channel 3, and when solid accumulation arrived predetermined altitude (b position), program control system was opened seal gate valve 14.Afterwards, the discharge rate that the height of materials that program control system detects according to passive nucleon stuff level switch 6 is regulated discharger 11, the height of materials (ab section) in predetermined altitude range in the control discharging channel.The height of materials of controlling satisfies the requirement of material sealing discharging passage 3 in the discharge process.
When pressing filter 21 was started working, seal gate valve 34 was closed, the height of materials that radio frequency admittance level-sensing device 26 detects in the discharging channel 23, and when solid accumulation arrived predetermined altitude (c position), program control system was opened seal gate valve 34.Afterwards, the discharge rate that the height of materials that program control system detects according to radio frequency admittance level-sensing device 26 is regulated discharger 31, the height of materials in the control discharging channel is located to fluctuate at predetermined altitude (c position).The height of materials of controlling satisfies the requirement of material sealing discharging passage 23 in the discharge process.
The drive disk assembly of discharger of the present utility model (motor and decelerator) can be arranged in outside the shell of discharger storehouse.
When material viscosity was larger, discharging channel can be designed to inverted tubaeform, and is smooth and easy to guarantee discharge.
The utility model discloses a kind of pressing filter discharge device; although more than enumerated less embodiment; but for those of ordinary skill in the art; some remodeling that the utility model is done, improvement, replacement etc.; perhaps above-mentioned embodiment is done any combination variation, all drops within the protection domain of the present utility model.
