Abstract
The invention discloses a filter cake blowing apparatus of a filter press. A feeding flange is welded on a filter press thrust plate; the filter press thrust plate is connected with a filter plate feed opening through a pipeline; a flange is arranged on a feeding pipeline and connected with the thrust plate feeding flange; a check valve and a feeding control valve are mounted on the feeding pipeline; a blowing pipeline is welded at the opening of the feeding pipeline; a check valve and a blowing control valve are mounted on the blowing pipeline; a safety valve and a pressure gauge are arranged at the upper end of a gas storage tank; a sewage drainage opening is formed in the lower end of the gas storage tank; a flange is arranged at the gas storage tank and connected with the blowing pipeline; the gas storage tank is connected with an air compressor or other gas sources; the blowing pressure of the gas storage tank is greater than the feeding pressure of a filter chamber; the gas volume of the gas storage tank is two times more than that of the volume of the filter chamber. With adoption of the filter cake blowing apparatus disclosed by the invention, the slurry in the feeding hole of the filter press filter plate and the slurry in the filter cake can be quickly discharged completely through high pressure blowing, so that the water content of the filtered filter cake can be reduced to be lowest, the filter cake can reach the purity after being filtered, and the filtrate recovery rate can be increased; the apparatus is simple in structure, convenient to mount and maintain and capable of improving the filter efficiency.
Description
Technical field
The present invention is filter plant filter press field, furthermore, relates to a kind of filter press filter cake blowing device.
Background technology
Filter press is the main filtration equipment of Separation of Solid and Liquid industry, filter press belongs to intermittent circulating filtration equipment, during filtration, material injects the filter chamber of filter plate by the pressure of feed pump, the particle retained in material by the filter cloth in each filter chamber forms filter cake, filtrate is discharged by the corner fluid hole of filter plate, pull open filter plate removal filter cake by plate pulling device after charging completes, a circulation completes, and realizes the object of Separation of Solid and Liquid.
At the scene use in filter press upon completion of filtration removal filter cake time find that there is weak point, because filter plate central well contains the material of filtered, fail to discharge containing original slip in this material, still fail to get rid of totally containing residual filtrate in the filter cake simultaneously filtered, when filter press pulls open filter plate removal filter cake, the filtrate that filter plate charging hole contains is fallen in company with filter cake simultaneously, the filter cake of filtration is made to add moisture again, the filter cake of removal does not reach designed degree of purity, decrease the rate of recovery of filtrate simultaneously, thus make filter efficiency be affected.
Summary of the invention
The object of the invention is to solve the weak point existed in above-mentioned background technology, and a kind of filter press filter cake blowing device is provided.
To achieve these goals, the invention provides a kind of filter press filter cake blowing device, pressure filter thrust plate welding charging flange is connected filter plate charging hole with pipeline, feed pipe is provided with Flange joint thrust plate charging flange, feed pipe installs check-valves and inlet control valve, at feed pipe opening welding blower duct, blower duct installs check valve and blowing control valve, air accumulator is set, this air accumulator upper end is provided with safety valve and Pressure gauge, air accumulator lower end is provided with sewage draining exit, air accumulator is provided with flange and is connected with blower duct, air accumulator connects air compressor machine or other source of the gas, the blow pressure that air accumulator is arranged should be greater than filter chamber feed pressure, air accumulator gas volume is greater than chamber space and answers more than twice.
Described welds blower duct at feed pipe opening, and the blower duct of welding is provided with adpting flange docking.
Described welds blower duct at feed pipe opening, and feed pipe welding blower duct is provided with the gradient of 30 degree to 45 degree.
The effect of being discharged through high pressure air blowing by slip in slip in enforcement filter press filter board charging hole of the present invention and filter cake, make the filter cake after filtration can drop to minimum moisture content through blowing, this blowing device is when filter press charging, the check valve that blower duct is installed is in closed condition, after charging completes, blowing starts, the check-valves that feed pipe is installed is in closed condition, blow pressure is greater than feed pressure wind-force can penetrate filter cake discharge filtrate, the gas volume of air accumulator is greater than more than chamber space twice and has enough high-pressure air sources, filter plate charging hole and filter cake make filtrate discharge totally fast through high pressure air blowing, filter cake is reached and filters rear designed degree of purity, increase the rate of recovery of filtrate, this apparatus structure is simple, installation and maintenance are convenient, improve filter efficiency.
Accompanying drawing explanation

Detailed description of the invention
Refer to shown in Fig. 1, the invention provides a kind of filter press filter cake blowing device, this device welds charging flange 9 at pressure filter thrust plate 10 and is connected filter plate charging hole 11 with pipeline, the flange that charging flange 9 connects feed pipe 8 uses bolted, the material that feed pipe 8 uses is seamless steel pipe, feed pipe 8 is installed check-valves 7 and is connected feed pump with inlet control valve 6, at feed pipe 8 opening welding blower duct 2, welding blower duct 2 is provided with the gradient of 30 degree to 45 degree, blowing air-flow can be made to enter chamber fast, the material that blower duct 2 uses is seamless steel pipe, blower duct 2 is installed check valve 4 and is connected with blowing control valve 3, blower duct 2 is provided with adpting flange 5 and uses bolted, air accumulator 1 is set, this air accumulator is provided with Pressure gauge 13 and safety valve 12, air accumulator 1 lower end is provided with sewage draining exit 14, air accumulator 1 is connected with blower duct 2, air accumulator 1 is provided with flange and is connected air compressor machine or other source of the gas with pipeline.
The blow pressure arranging air accumulator 1 is greater than the feed pressure of feed pump, blow pressure is greater than feed pressure and can penetrates filter cake and discharge filtrate fast, high pressure air blowing makes the filtrate of filter plate charging hole 11 slip and filter cake remnants blow clean, air accumulator 1 gas volume is greater than chamber space and answers more than twice, air accumulator 1 gas volume has greatly enough high-pressure air sources, this blasting method makes filter cake reach the degree of purity of filtration, increases the rate of recovery of filtrate simultaneously.
