Abstract
The invention relates to a filter central tube, and particularly relates to a spiral punching-type filter central tube. A tube body of the filter central tube comprises narrow steel strips which wind in spirally staggered manner, an upper narrow steel strip is fixedly connected with a lower narrow steel strip, and the narrow steel strips are provided with punched holes along the length direction. The rigidity of the central tube is efficiently enhanced by the staggered spiral winding structure of the narrow steel strips; the narrow steel strips spirally wind to a required diameter, and then are cut into the required length by a spiral cutter of a device, so that the filter central tube is simple and convenient to process; and when the sizes of the punched holes in the narrow steel strips are changed from Phi 3 to Phi 4.5, the passing performance of circulating media of the central tube is improved.
Description
Technical field
The present invention relates to a kind of filter central pipe, relate in particular to a kind of spiral flushing cellular type filter central pipe.
Background technology
Central tube is one of part of cleaner, has played the support filter core, makes its on-deformable effect.Central tube spreads all over aperture, so that the medium to be filtered such as liquid or gas can smooth and easy passing through.So the size of central tube rigidity and the trafficability characteristic of circulation medium are particularly important.
What used central tube adopted in the past is the 0.4mm steel plate, and the surface strikes out the aperture of φ 3, is rolled into the pipe of various diameters by equipment, and last steel plate is fixed by riveted, makes it stable shaped, not loose.The shortcoming such as the central tube of this pattern exists processed complex, high to equipment requirement, steel plate materials is thick and the medium trafficability characteristic is poor.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the deficiencies in the prior art, and a kind of processing of being convenient to is provided, and improves the spiral flushing cellular type filter central pipe of the trafficability characteristic of the size of central tube rigidity and circulation medium.
The present invention is achieved by the following technical programs:
A kind of spiral flushing cellular type filter central pipe, the pipe shaft of described filter central pipe is the narrow steel strip of dislocation coiled coil, described upper strata narrow steel strip and lower floor's narrow steel strip are affixed, describedly are provided with punching along its length direction.
Described narrow steel strip upper punch hole size is φ 4.5.
The invention has the beneficial effects as follows:
Because the pipe shaft of described filter central pipe is the narrow steel strip of dislocation coiled coil, described upper strata narrow steel strip and lower floor's narrow steel strip are affixed, describedly are provided with punching along its length direction.Narrow steel strip dislocation helix-coil structure effectively raises the rigidity of central tube, and with the narrow steel strip helical coil to the diameter that needs, the length that the spiral cutter cutting by equipment needs is so that process easy; When narrow steel strip upper punch hole size changes φ 4.5 into by φ 3, improve the trafficability characteristic of central tube circulation medium.
Description of drawings
Fig. 1 is main TV structure schematic diagram of the present invention.
Among the figure: 1. narrow steel strip, 2. punching.
The specific embodiment
In order to make those skilled in the art understand better technical scheme of the present invention, the present invention is described in further detail below in conjunction with accompanying drawing and most preferred embodiment.
As shown in Figure 1, the pipe shaft of filter central pipe of the present invention is the narrow steel strip 1 of dislocation coiled coil, and described upper strata narrow steel strip and lower floor's narrow steel strip are affixed, describedly are provided with punching 2 along its length direction.
Because the pipe shaft of described filter central pipe is the narrow steel strip of dislocation coiled coil, described upper strata narrow steel strip and lower floor's narrow steel strip are affixed, describedly are provided with punching along its length direction.Narrow steel strip dislocation helix-coil structure effectively raises the rigidity of central tube, and with the narrow steel strip helical coil to the diameter that needs, the length that the spiral cutter cutting by equipment needs is so that process easy; When narrow steel strip upper punch hole size changes φ 4.5 into by φ 3, improve the trafficability characteristic of central tube circulation medium.
The above only is preferred embodiment of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
Claims (2)
1. a spiral flushing cellular type filter central pipe is characterized in that, the pipe shaft of described filter central pipe is the narrow steel strip of dislocation coiled coil, and described upper strata narrow steel strip and lower floor's narrow steel strip are affixed, describedly are provided with punching along its length direction.
2. a kind of spiral flushing cellular type filter central pipe according to claim 1 is characterized in that, described narrow steel strip upper punch hole size is φ 4.5.
