Detailed description of the invention

In order to further illustrate technical scheme, in conjunction with accompanying drawing, the specific embodiment of the present invention being described, such as Fig. 1, Fig. 2, select plate steel plate as walking track 1 in this example, thickness 12 millimeters, length is identical with pressure filter rack, width 120 millimeters；Select two and be separately mounted to pressure filter both sides；This example is selected rectangular steel pipe as the raw material of support 2, be respectively adopted 4 perpendicular supports and 8 lateral frames are welded to form support 2；To include power set, vertical rail, travelling carriage, directive wheel, the parts composition up and down motion device 3 of the element such as driving chain, and be installed on support 2；Select the flexible drag chain that the industry is general as flexible drag chain 4 up and down and the flexible drag chain 5 of walking, corresponding length is intercepted up and down respectively according to the stroke of the stroke of up and down motion device and running gear, being connected with travelling carriage one end of flexible drag chain 4 up and down, the other end is connected with support；One end of flexible for walking drag chain 5 is connected with support 2, the other end is connected with pressure filter rack, and respectively water supply line and control circuit and power circuit are arranged on upper and lower flexible drag chain 4 and walk in flexibility drag chain 5, and walking flexibility drag chain 5 is placed in walking dee 6；This example is selected U-shaped Steel Thin-Wall as walking dee 6, opening upwards, be arranged on walking drag chain support 7；Selecting the bracing frame that the industry is general as walking dee support 7 in this example, be separately mounted to the two ends of walking dee 6, its underpart is fixedly mounted on pressure filter rack；Side plate, sprocket wheel, the running gear 8 of mounting seat will be included, be arranged on below support 2, and be connected with traveling control device 9；In this example, traveling control device 9 adopts and includes road wheel, limit track, position-limited wheel, stepping is taken turns, the parts of stepped track composition are arranged on walking track 1, and the walking for controlling running gear 8 is not skewed, and travel distance is easily controllable, also ensuring that during a whole set of rinser walking not skewed, travel distance is easily controllable；Adopting the steel water pipelines of the diameter 25 millimeters that the industry is general as horizontal water tube and vertical water pipe in this example, be connected and fixed on travelling carriage by one end of vertical water pipe and water source, lower end is connected with horizontal water tube；This example adopts on horizontal water tube and make hole for water spraying in the horizontal direction as water injector, lateral arrangement, 20 millimeters of interval, the space that to be covered with on horizontal water tube equal with filter plate width, by horizontal water tube closed at both ends, it is formed for cleaning conduit assembly 10, by walking driving chain 11, movable motor 12 is separately mounted between running gear 8 and support 2, select the chain that the commercially available industry is general as driving chain 11, select commercially available servomotor as movable motor 12, both sides running gear 8 is equipped with a walking driving chain 11, movable motor 12, just complete the enforcement of the present invention；During application, chamber filter press peace carries out normal operation according to the working method that the industry is general, and when work needs to clean filter cloth to a certain extent, the filter plate drawing device in pressure filter main body starts, and pulls open filter plate in a determining deviation；nullStart this device，The movable motor 12 controlled on system command running gear 8 starts，Drive walking driving chain 11 thus driving traveling control device 9 to move along walking track 1，Thus driving traveling control device 9 to move in orbit，Also just drive whole filter plate rinser along the horizontal motion of pressure filter main body，To when moving to the filter plate position needing to clean，Running gear 8 stops，Up and down motion device 3 starts，Travelling carriage motion drives cleaning conduit assembly 10 to move downward，When on cleaning conduit assembly 10 motion arrival filter plate along position，Start water source，The water with certain pressure sprays from cleaning conduit assembly 10，Clean the attachment of filter cloth on filter plate，When cleaning the bottom that conduit assembly 10 moves to filter plate，Control system command up and down motion device 3 to move upward，Cleaning conduit assembly 10 is driven to move upward，The filter cloth that conduit assembly 10 continues to spray on filter plate is cleaned while motion，When again cleaning conduit assembly 10 motion and arriving filter plate top edge，Control system command up and down motion device 3 again to move downward，Repeat above-mentioned action，Until filter cloth is cleaned；Moving back and forth number of times and cleaning the irrigation pressure of conduit assembly 10 of its up and down motion device 3, is according to the character of attachment on the material filtered and filter cloth with how much by controlling default；After one piece of filter plate has cleaned, up and down motion device 3 rests on home position, upper end, running gear 8 starts, stop behind one filter plate interval of pressure filter bulk motion, its up and down motion device 3 starts, and repeats above-mentioned work process, until all filter plates all clean up, running gear 8 and up and down motion device 3 return home position, and pressure filter recovers normal operation.In order to realize travelling control, selecting the round steel of diameter 16 millimeters as wheel shaft 22, its one end is produced external screw thread M16, the diameter selecting sheave 23 is 100 millimeters, thickness 20 millimeters, the width of excircle rectangular channel 13 millimeters, the degree of depth 12 millimeters；Select the reference diameter 80 millimeters of gear 24, modulus 2, gear thickness 20 millimeters；Locking nut 21 selects national standard M16 outer-hexagonal plain nut, is arranged on running gear by wheel shaft 22 and locks with locking nut 21；The groove of sheave 23 is nested on guide rail, it is ensured that groove runs along guide rail, it is ensured that running gear 8 not sideslip；Gear 24 is engaged with the tooth bar in stepped track, it is ensured that gear 24 run the control receiving control system, do not make running gear 8 walk out of control, be conducive to controlling distance controlling when each piece of filter plate cleans accurate.
