Detailed description of the invention
For a better understanding of the present invention, below in conjunction with specific embodiments and the drawings, the present invention is conducted further description.
As depicted in figs. 1 and 2, the horizontal dirt separator of a kind of automatically cleaning, comprises body 1, the screen pack 4 be arranged in body 1, the blowdown assembly 6 be connected with body 1, cleaning assemblies 8 and the movable component 9 driving cleaning assemblies 8 to move and Control Component.
Body 1 is provided with arrival end and the port of export.Arrival end place is provided with neck tube 2, and its radius is less than the radius of body 1.The port of export place of neck tube 2 and body 1 is equipped with flange 3, owing to being sealably coupled in pipeline by body 1.Screen pack 4 is arranged in body 1, removably connects with body 1.The aperture of screen pack 4 is less, is mainly applicable to the fluid that dirt particle is little, and these undersized dirts easily block screen pack 4, and not easily goes out by shearing, and needs cleaning device and screen pack 4 close contact, continuous operation.Blowdown assembly 5 is arranged on close screen pack 4 towards the side of arrival end, which is provided with blowoff valve.Dirt is tackled by screen pack 4, discharges body 1 by blowdown assembly 5.Base 6 supports fixed body 1, and it can directly fix on the ground, also can be fixedly connected with other anchoring base.
Cleaning assemblies 8 comprises cleaning brush 802, drives the electric rotating machine 803 of cleaning brush 802 and the support bar 801 of fixed support electric rotating machine 803.Electric rotating machine 803 is arranged on the lower end of support bar 801, is fixedly connected with support bar 801, the axis of its output shaft or conllinear parallel with the axis of body 1.Cleaning brush 802 is fitted the side of screen pack 4 towards the arrival end of body 1, and it is fixedly connected with the output shaft of electric rotating machine 803, and electric rotating machine 803 drives cleaning brush 802 at vertical rotation in surface.Cleaning brush 802 is at least two, and the output shaft along electric rotating machine 803 is arranged symmetrically.Wherein at least one cleaning brush 802 is provided with hard bristle, and at least one cleaning brush 802 is provided with soft bristle.The material of hard bristle is stainless steel, iron, high molecular polymer etc., and the material of soft bristle can be plastics, rubber etc.The intensity of two kinds of bristles is different, cleans respectively to screen pack 4.
Movable component 9 comprises support, motion bar 901, horizontal air cylinder and vertical cylinder.Vertical cylinder is fixed on support, and its output shaft is fixedly connected with horizontal air cylinder.One end of motion bar 901 is fixedly connected with the output shaft of horizontal air cylinder, and the other end is fixedly connected with support bar 801.The lower surface of motion bar 901 is provided with projection.Thus drive cleaning assemblies to enter and pass body 1.
Body 1 is also provided with the conduit 7 of opening upwards.The upper surface of conduit 7 is provided with around the conduit brace table of 7 one weeks, brace table and conduit 7 one-body molded.Brace table has the chute 701 matched with the projection on motion bar 901.The length direction of chute 701 parallels with the axis of body 1.The face (being the rightmost side in Fig. 1) that the inner surface of conduit 1 port of export apart from body 1 is nearest is fixed with retainer ring 702, and its opening direction is parallel with the axis of body 1.When horizontal air cylinder drives support bar 801 to low order end, retainer ring 702 clamps support bar 801.
Control Component comprises pressure sensor and controller.Pressure sensor is arranged in body 1, between screen pack 4 and blowdown assembly 5, and the pressure of induction body 1 inner fluid.Controller receives the signal of pressure sensor, level of control cylinder, vertically cylinder and electric rotating machine motion.
When using the horizontal dirt separator of automatically cleaning provided by the invention, the pressure of fluid before pressure sensor induction screen pack 4, when screen pack 4 is obstructed to a certain degree, when the pressure of fluid increases to above preset value, pressure sensor outputs signal to controller.Controller level of control cylinder and vertical cylinder moving afterwards.Vertical cylinder moving, drive horizontal air cylinder and cleaning assemblies 8 to move downward, fall into chute 701 to projection, motion bar 901 is positioned on brace table, the axis of electric rotating machine 803 and the axis collinear of body 1.Afterwards, horizontal air cylinder moves, and protruding slides along chute 701, clamps support bar 801 to retainer ring 702, and cleaning brush 802 is fitted screen pack 4.The electric rotating machine 803 of controller control afterwards moves, and drives cleaning brush 801 cleaning filter net 4, is swept down by the dirt of blocking screen pack 4, and discharges body 1 by blowdown assembly 5.
Above embodiments of the invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the scope of the invention change and improve, and all should still belong within this patent covering scope.
