Abstract
The utility model relates to a base structure of machine tool, and in particular to a shock-absorption improved structure of a horizontal-type helical centrifuge base. The shock-absorption structure of the centrifuge base comprises a rectangular framework (1) which is formed by welding hollow square steel pipes into a plane, and sand grains (4) are fulfilled into the hollow square steel pipe, and the opening of the hollow square steel pipe is closed by a steel plate. The shock-absorption structure of the centrifuge base effectively increases the weight of the centrifuge base, and improves the stability o the machine; at the same time, the sand grains are adopted as the stuffing, the structure adopting the sand grains as filling is more economic and convenient compared with that adopting the solid steel pipe and other materials as filling. The sand grain filling quantity can be reasonably distributed, so that the original frequency of the system can be effectively improved, and the resonance vibration of the centrifuge system can be effectively prevented; especially when the centrifuge is started and stopped, the structural damage of the centrifuge can be prevented. The running quality of the centrifuge is improved, and the service life of the device is prolonged.
Description
(1) technical field
The utility model relates to a kind of understructure of work mechanism, particularly relates to a kind of shockproof structure-improved of horizontal spiral centrifuge base.
(2) background technology
Known, horizontal spiral centrifuge is the density contrast that relies on the solid-liquid two-phase, and under action of centrifugal force, the sinking speed of accelerating solid phase particles realizes the separation machinery of Separation of Solid and Liquid.Along with the needs of environmental protection in modern age, disposal of three wastes development, for all raisings gradually of requirement of industrial wastewater and sludge dewatering treatment.Because it is very fast that therefore characteristics such as the unique continued operation of horizontal screw centrifuge, treating capacity is big, adaptability is strong develop.
In the decanter type horizontal screw centrifuge, in product design process, usually need requirement according to product design, rationally determine various parameters, for example: weight, cost, performance, bearing capacity or the like, in the hope of reaching best design object.In the decanter type horizontal screw centrifuge, the centrifuge base is an important components.The centrifuge parts substantially all are installed on the centrifuge base, and it play supporting role to each main parts size of centrifuge, are also undertaking the effect of transmitted load and vibration simultaneously.The decanter type horizontal screw centrifuge is owing to there is high-speed rotary part, and therefore the base designs quality of a centrifuge has decisive role to the stable of whole centrifuge and performance.The stability of centrifuge base, shockproof properties not only influence quality, the efficient of wastewater treatment, but also can influence precision, the life-span of infringement machinery equipment.
The decanter type horizontal screw centrifuge of prior art all adopts complete fuselage bearing; promptly be welded into the rectangular frame that is the plane by the hollow square steel tube; corner location in the rectangular frame bottom is welded to connect the understructure that four supports form; though can installing the decanter type horizontal screw centrifuge thereon, this kind fuselage support base turns round; but because center of gravity is higher; when centrifuge moves; especially relative easier generation rocking vibration when starting with shutdown; influence the concentricity of rotary part; cause the two supports bearing life to reduce indirectly and damage; this structure is had higher requirement to the material of supporting leg simultaneously; once there were some producers that supporting leg cracking and distortion took place, brought certain influence and hidden danger to production.
The shockproof properties of base is further improved in the urgent hope in horizontal spiral centrifuge market.
(3) utility model content
The purpose of this utility model intends providing a kind of structure-improved of decanter type horizontal screw centrifuge base, to improve the shockproof properties of base.
The purpose of this utility model is achieved through the following technical solutions:
A kind of shockproof structure of centrifuge base comprises by the hollow square steel tube being welded into the rectangular frame that is the plane, it is characterized in that filling sand grains in the hollow square steel tube is sealed by steel plate at hollow square steel tube oral area.
Described sealing is the Type of Welding sealing.
Welding addition hollow square steel tube reinforced pipe in the rectangular frame on described plane.
Described hollow square steel tube filling sand grains is that the sand grains charging quantity of single steel pipe inner chamber is for all being full of or the part filling.
The sectional dimension of described hollow square steel tube is 15 to 25 centimetres.
Welding addition steel plate reinforcement/plate on the rectangular frame on described plane.
Design and evidence as calculated,, select the hollow square steel tube of appropriate size for use, needn't be welded to connect support again it installs the operation needs of horizontal spiral centrifuge above having satisfied highly in the rectangular frame bottom on the plane that forms, do not hinder the configuration and the operation of top horizontal spiral centrifuge at all, lift the position of centre of gravity that has reduced base thus, also reduce the position of centre of gravity of horizontal spiral centrifuge, increased the stability of base.
Filling sandstone in forming the hollow square steel tube of rectangular frame has increased the weight of the weight of rectangular frame, has increased the shockproof stability action of base more.
Optionally in each hollow square steel tube, all be full of or part filling sand grains, can adapt to the different vibration of equipment everywhere, produce shock attenuation result more targetedly.
Generally speaking, the advantage and the beneficial effect of the technical program are: 1. increased centrifuge base deadweight effectively, reduced the centrifuge Oscillation Amplitude that caused by rotary part, thereby reduced parts damages and the noise that vibration causes, improved the stability of machine; Adopt sand to have more economy and convenience than adopting solid steel and filling other materials simultaneously as filler.2. reasonably distribute each several part back-up sand amount, can effectively improve the intrinsic frequency of system, can effectively suppress the centrifuge system and resonate, especially centrifuge avoids taking place centrifuge structure destruction when starting and shut down; 3. than steel better absorbing performance is arranged, can the absorption portion vibration.Vibration is transmitted between the sand grains particle, by the collision between sand grains, partial vibration can be converted into heat energy, thereby reaches the purpose of vibration damping.
By adopting above measure and structure, make the decanter type horizontal screw centrifuge under various operating modes, vibrate forr a short time, move more stable, reliable.
