Abstract
A counter-blower discharging device for a vacuum filter belongs to the technical field of mineral processing equipment, and is provided at the aim of solving the technical problem so as to ensure that the discharging production efficiency of a disk filter is improved, and the capability of a flotation system is effectively improved. The counter-blower discharging device adopts the technical scheme as follows: the counter-blower discharging device comprises a wind source, a blast pipe, a valve and a control loop; one end of the blast pipe is connected with the wind source; the other end of the blast pipe is connected with a discharge area for a distributing head of the vacuum filter; the valve is installed on the blast pipe; the control loop is connected with the valve; and the wind source is connected with a compressed air pipeline. The counter-blower discharging device can perform the powerful discharging by utilizing high-pressure counter blowing through an original atmosphere interface when in discharging, and material that enters the discharge area can drop off under the pressure generated from the inner part of a filter fan; in addition, the counter-blower discharging device obviously improves the efficiency of the filter, reduces the circulating operation of the material, and improves the production efficiency of the flotation system.
Description
Technical field
The utility model relates to the device for discharging in a kind of vacuum filter material dewatering process, belongs to the preparation equipment technical field.
Background technology
In floatation clean coal dehydration equipment disc vacuum filter running, it takes off the external atmosphere discharging that cake has used the back, region of no pressure, when the cleaned coal cake has experienced absorption, dehydration back to discharge zone, because entering of air makes negative pressure become normal pressure, get loose thereby material vibrated, form discharging.In recent years along with the development of producing, the coal amount increases considerably, and the ability of original equipment design is limited by field condition, causes the cleaned coal dewatering efficiency to reduce, thereby whole coal washing work is impacted.Therefore, for enhancing productivity, it is very necessary seeking better and more effective device for discharging and method.
The utility model content
Technical problem to be solved in the utility model provides a kind of blowback wind device for discharging that is used for vacuum filter that can improve disc vacuum filter discharging production efficiency and effectively promote the floatation system ability.
The technical scheme that solves the problems of the technologies described above is:
A kind of blowback wind device for discharging that is used for vacuum filter, it is made up of wind regime, airduct, valve, control loop, one end of airduct is connected with wind regime, the other end of airduct is connected with vacuum filter dispensing head discharge zone, valve is installed on the airduct, control loop is connected with valve, and wind regime is connected with air line.
The above-mentioned blowback wind device for discharging that is used for vacuum filter, described control loop is made up of position sensor and related electric device.
Adopt the blowback wind device for discharging of this structure, after the disk of vacuum filter forwards the relevant position to, the by-pass valve control action, high-pressure blast is blown in the filtrate pipe that does not have pressure and filter fan of filter distribution head discharge zone, from inside to outside filter cake is become flexible and make it to come off, significantly improve discharging efficient and reduced the circular flow of coal slime, improved production efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Mark is as follows among the figure: vacuum filter dispensing head discharge zone 1, vacuum filter dispensing head drying zone 2, vacuum filter dispensing head adsorption zone 3, wind regime 4, airduct 5, valve 6, control loop 7.
The specific embodiment
Show among the figure that the utility model is made up of wind regime 4, airduct 5, valve 6, control loop 7..One end of airduct 5 is connected with wind regime 4, and wind regime 4 is connected with the air line at scene, and the other end of airduct 5 is connected with vacuum filter dispensing head discharge zone 1, and high-pressure blast enters vacuum filter dispensing head discharge zone 1 by airduct 5.Valve 6 is installed on the airduct 5, and control loop 7 is connected with valve 6, and control loop 7 is made of with relevant electrical equipment position sensor, is used for by-pass valve control 6 and opens and closes where necessary.
Show among the figure that the vacuum filter dispensing head has vacuum filter dispensing head discharge zone 1, vacuum filter dispensing head drying zone 2,3 three parts of vacuum filter dispensing head adsorption zone.Coal slime is passed through vacuum filter dispensing head adsorption zone 3, vacuum filter dispensing head drying zone 2 respectively in filter process, this two district is connected with vacuum, carry out suction and dehydration, again by vacuum filter dispensing head discharge zone 1, this district links to each other with atmosphere, utilize the zero pressure discharging that gets loose, enter following one-period through a joint dead zone again.
Show among the figure that airduct 5 of the present utility model uses the blowback wind of high pressure to carry out powerful discharging at the protoatmosphere interface, the material that enters vacuum filter dispensing head discharge zone 1 is subjected to coming off from filter fan pressure inside, reaches the purpose of smooth discharging.
Control loop 7 of the present utility model can be connected with the air-valve drive unit by the PLC control device, positions with limit switch, compares the back start signal output air-valve drive unit work of calculating with the signal bits of the program setting of PLC.This method with the PLC accessory drive is a mature technique technically, repeats no more.
The utility model can adopt manually-operated and control two kinds of patterns automatically when work.During manually-operated, the time according to the rules start or stop air supply device, carry out discharging by operating personnel.When adopting control automatically, the PLC control device is connected with the air-valve drive unit, position with limit switch.
