Abstract
The invention discloses a connecting rod used for a suction filtration machine dewatering system. The connecting rod comprises a middle connecting rod body and two end connecting rod bodies which are the same in structure. The middle connecting rod body is a hollow seamless steel pipe. The two end connecting rod bodies are symmetrically installed on the two sides of the middle connecting rod body in an inserted mode and are welded and fixed. Threads are arranged on the two end connecting rod bodies. The end connecting rod bodies are made of 0Cr19Ni9 steel. According to the connecting rod used for the suction filtration machine dewatering system, an original overall connecting rod design structure is changed into a segmented welding structure, the size of the middle connecting rod body is increased, so that the connecting rod is attached to a filter fan better; shaking in the production process is reduced, a whole fan plate is located in a compact integral structure, the integral structure strength is improved, and the situation that the stress borne locally is too large is avoided; and meanwhile, the force bearing point of the connecting rod is skillfully transferred to the welding position through the structure, the end connecting rod bodies are inserted into the middle connecting rod body by enough length, and the stress can be effectively dispersed, so that a stress concentration part is changed from a point to a surface, and the connecting rod stress bearing level is effectively improved.
Description
Technical field
The present invention relates to feed system field, be specifically related to the dewatering system connecting rod of a kind of rotary vacuum filter.
Background technology
Dewatering system is the important throat of rotary vacuum filter, its connecting rod used is the bar linkage structure of whole round steel cutting thread, the connecting rod strength of this form is low, is susceptible to fracture, and connecting rod cracking situation once occurs, will result in rotary vacuum filter stuck, in turn resulting in only material, fracture phenomenon, the serious accident that will result in is stopped kiln, is affected production yields and quality, and cause thermal loss and raw materials for production loss, cause cement quality unstable.
Summary of the invention
In order to solve above-mentioned technical problem, the present invention provides the dewatering system connecting rod of a kind of rotary vacuum filter, and this connecting rod is changed into segment welded structure by the design structure of the most whole connecting rod, improves intensity and the service life thereof of connecting rod, reduce the loss of enterprise, meet its production requirement.
The purpose of the present invention implements by the following technical programs:
A kind of dewatering system connecting rod of rotary vacuum filter, including the end connecting rod that stage casing connecting rod and two root architectures are identical, described stage casing connecting rod is the seamless steel pipe of hollow, and both ends connecting rod symmetry grafting is arranged on the both sides of stage casing connecting rod and is welded and fixed, and is provided with screw thread on the connecting rod of both ends.
Further, described end connecting rod is made up of 0Cr19Ni9 steel.
The dewatering system connecting rod of a kind of rotary vacuum filter of the present invention, this connecting rod is changed into segment welded structure by the design structure of the most whole connecting rod, stage casing connecting rod is amplified, connecting rod is made more to fit filter fan, reduce rocking in production process, make whole fan plate be among a more close overall structure, increase overall construction intensity, it is to avoid the situation that local meets with stresses excessive occurs；Meanwhile, connecting rod stress point is transferred to weld by this structure cleverly, the length that end connecting rod is enough in inserting stage casing connecting rod, can effective dispersive stress, make stress concentration portion position be changed into face by point, effectively raise the level that connecting rod meets with stresses.
Accompanying drawing explanation
Below according to drawings and Examples, the present invention is described in further detail.
Fig. 1 is the structural representation of the dewatering system connecting rod of a kind of rotary vacuum filter of the present invention.
In figure: the connecting rod of 1-stage casing；2-end connecting rod；3-screw thread.
Detailed description of the invention
As shown in Figure 1, the dewatering system connecting rod of a kind of rotary vacuum filter described in the embodiment of the present invention, including the end connecting rod 2 that stage casing connecting rod 1 and two root architectures are identical, stage casing connecting rod 1 is the seamless steel pipe of hollow, the symmetrical grafting of both ends connecting rod 2 is arranged on the both sides of stage casing connecting rod 1 and is welded and fixed, and is provided with screw thread 3 on both ends connecting rod 2.
The present invention is changed into segment welded structure by the design structure of the most whole connecting rod, stage casing connecting rod is amplified, connecting rod is made more to fit filter fan, reduce rocking in production process, whole fan plate is made to be among a more close overall structure, increase overall construction intensity, it is to avoid the situation that local meets with stresses excessive occurs；Meanwhile, connecting rod stress point is transferred to weld by this structure cleverly, the length that end connecting rod is enough in inserting stage casing connecting rod, can effective dispersive stress, make stress concentration portion position be changed into face by point, effectively raise the level that connecting rod meets with stresses.
One preferred embodiment, be made up of 0Cr19Ni9 steel by end connecting rod 2, has good plasticity, toughness, weldability, makes connecting rod more durable.
After transformation, service life reaches 100% the connecting rod occupation rate of 20 days to 25 days, and within more than 25 days, connecting rod occupation rate reaches 97.25%, either the most numerically has on the time and significantly promotes.Transformation front rod is concentrated mainly on 10-15 days and accounts for 85% service life.By statistics, transform first 5 months totals and employ 993 connecting rods, transform latter 5 months and use 338, average every month saves 131, connecting rod, annual connecting rod productivity effect of saving is 68 yuan/root=106896 yuan of=131 * December *, greatly reduces the production cost of enterprise, it is easy to promote the use of.
Last it is noted that the foregoing is only the preferred embodiments of the present invention; it is not limited to the present invention; for a person skilled in the art; technical scheme described in foregoing embodiments still can be adjusted by it; or wherein portion of techniques feature is carried out equivalent; all within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
