Description

Technical Field

[0001] The utility model relates to the technical field of flexible filter tube and tubular membrane assembly, in particular to a filter tube external positioning device. Background Art

[0002] In the production process of flexible filter tube membranes, a large number of flexible filter tubes need to be positioned one-to-one at both ends. The larger the size of the membrane shell, the more flexible filter tubes are installed. If the filter tubes are installed inside the membrane tube, they will often be misaligned during the production process and fail to meet the process requirements of the membrane tube. Therefore, it is necessary to develop a device for positioning and assembling the filter tubes externally, and it is urgent to overcome the following technical difficulties:

[0003] 1. During the injection molding process, the skeleton in the middle of the flexible filter tube will have a certain error in the parts. A large number of flexible filter tubes will have different positioning distances at both ends during installation. If the positioning plate distance cannot be adjusted according to the actual length of the filter tube, the filter tube will bend or stretch during production, which is not conducive to the overall performance of the membrane tube.

[0004] 2. Due to the installation method of external positioning filter tube, when installing the flexible filter tube, it is necessary to install, position and remove the positioning plates at both ends. This requires the operator to accurately install and remove the positioning plates to meet the requirements, which is time-consuming and labor-intensive, and the assembly effect is uncertain.

DETAILED DESCRIPTION

[0025] A filter tube external positioning device, see Figure 1-Figure 4 , which includes a base 10, at least one set of position adjusters 20, two sets of positioning plates 30, and two sets of positioning seats 40.

[0026] In specific implementation: each set of positioning plates 30 and positioning seats 40 are assembled to form a guide mechanism, which only includes one set of position regulators 20. The two sets of guide mechanisms include a first guide mechanism 50 with a fixed position and another second guide mechanism 60 with an adjustable position.

[0027] In a specific implementation, the base 10 is arranged along the length direction of the filter tube 70. The base 10 includes a plurality of bottom support seats 11, longitudinal beams 12 on both sides of the upper portion, and a plurality of transverse beams 13 on the upper portion. The length of the base 10 is greater than the length of the filter tube 70 to be assembled.

[0028] The position regulator 20 includes a power end 21, a mounting base 22, a screw module 23, and a linear output end 24;

[0029] Each set of positioning plates 30 includes a circular plate 31 and an outer ring plate 32. The outer ring plate 32 is sleeved on the outer circumference of the circular plate 31. The circular plate 31 is provided with a plurality of filter tube positioning holes 311. The outer ring plate 32 has a thickness D.

[0030] Each positioning seat 40 includes a bottom plate 41 and a U-shaped frame positioning mechanism 42. The U-shaped frame positioning mechanism 42 includes two side frames 43 and a bottom frame 44. The two side frames 43 are connected to form an integral structure through the bottom frame 44. The bottom frame 44 of the U-shaped frame positioning mechanism 42 is welded to the upper surface of the bottom plate 41. The bottom plate 41 is provided with a group of first connection holes 411 for fixing the two side positions of the base 10 and a group of second connection holes 412 for fixing the center position of the linear output end 24. The upper portion of the U-shaped frame positioning mechanism 42 is open, and the upper portions of the two side frames are open. The net space thickness of the side frames 43 and the bottom frame 44 is equal to the thickness D of the positioning plate 32.

[0031] Each set of positioning plates 30 and positioning seats 40 are assembled together to form a guide mechanism, and the outer ring plates 32 of each set of positioning plates 30 are respectively positioned and inserted into the net space thickness area of the U-shaped frame positioning mechanism 42.

[0032] In a specific implementation, the position adjuster 20 is disposed on the left side in the longitudinal direction of the base 10 , the bottom plate 41 of the first guide mechanism 50 is fixed to the linear output end 24 located below it, and the bottom plate 41 of the second guide mechanism 60 is fixed to the right side in the longitudinal direction of the longitudinal beams 12 on both sides of the base 10 ;

[0033] The bottom of the bottom frame 44 is hollowed out, and the bottom plate 41 is provided with an upward convex positioning boss 413 corresponding to the central area of the bottom frame 44. The top and bottom of the outer ring plate 32 are provided with notch grooves 321. When the guide mechanism is assembled, the bottom notch groove 321 of the outer ring plate 32 is aligned with the positioning boss 413, which makes the radial position of the guide mechanism locked firmly and reliably.

[0034] In a preferred embodiment, the outer ring plate 32 is composed of an upper half ring plate 33 and a lower half ring plate 34. The central ring walls of the upper half ring plate 33 and the lower half ring plate 34 are respectively provided with radial position locking protrusions 35. The ends of one diameter of the circular plate 31 are respectively provided with notched grooves 312. The notched grooves 312 of the circular plate 31 are respectively arranged to correspond to the locking protrusions 35, which makes it easy to reliably align the filter tube positioning holes 311 of the circular plates 31 on different guide mechanisms.

[0035] Circumferential baffles 36 are respectively provided on both sides of the upper half ring plate 33 and the lower half ring plate 34 corresponding to the thickness direction of the circular plate. The circumferential baffles 36 do not interfere with the arrangement of the filter tube positioning holes 311, which enables the outer ring plate 32 and the circular plate 31 to be assembled with different arrangements of filter tube positioning holes, thereby saving costs.

[0036] The working process of the filter tube external positioning device is as follows:

[0037] S1. Insert the positioning plate directly into the positioning seat;

[0038] S2. Snap the notch of the positioning plate into place with the positioning boss of the positioning seat so that the positioning plate cannot move left or right or front or back relative to the positioning seat, thus completing the guide mechanism.

[0039] S3. Install the filter tube into the filter tube positioning holes of the positioning plates at both ends of the base. Adjust the distance between the two sets of positioning plates by adjusting the hand wheel of the position adjuster according to the actual length of the filter tube. Stop adjusting after the filter tube is level and fix the position of the left positioning plate.

[0040] S4. Install the filter tubes on both sides at the same time, from left to right and from bottom to top;

[0041] S5. After assembly, check whether the filter tube is misaligned;

[0042] S6. After checking that there is no misalignment and deformation of the filter tube, remove the positioning plates on both sides of the installed filter tube and the filter tube directly from the device and push them into the membrane tube for the next installation.

[0043] Its working principle is as follows: each set of positioning plates and positioning seats are assembled to form a guide mechanism, and the two sets of guide mechanisms are respectively placed at both ends of the base. At least one set of position adjusters is set according to actual needs. According to the length of the filter tube, the position of at least one set of guide mechanisms on the base is adjusted so that the filter tube positioning holes on the circular plates of the two sets of positioning seats corresponding to the two sets of guide mechanisms correspond to each other and are arranged in a horizontal straight line. Then, the filter tubes are assembled in sequence according to the set order to the filter tube positioning holes to complete the assembly of the filter tubes. It ensures that the filter tubes are accurately installed in position and the assembly is adjusted according to the length of the filter tubes. The installation is simple, fast and reliable.
