Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The utility model provides a seamless steel pipe with filtering capability, as shown in figure 1, 2, including body 1, body 1 both ends all are provided with filtering component 2, and body 1 can carry out the prefiltering to the fluid that gets into body 1 when carrying fluid, also can prevent when improving the fluid purity that body 1 inner wall is contaminated or is blockked up.

As shown in fig. 2 and 3, the filtering assembly 2 includes a circular filtering plate 21, a filtering net 22 is installed in the middle of the filtering plate 21, the inner walls of both ends of the tube 1 are fixedly connected with fixing rings 11, the outer diameters of which are tightly attached to the inner walls of the tube 1, and one side of the fixing ring 11, which deviates from the opening of the tube 1, is connected with the filtering plate 21 through a connecting piece 3. Connecting piece 3 includes and is the circular shape spliced pole 31 with two sections that filter 21 one side is connected along circumference interval, spliced pole 31 one end fixedly connected with diameter is greater than the connection plectane 32 of spliced pole 31 diameter, connection plectane 32 is the vertical state with spliced pole 31, gu fixed ring 11 all offers the spread groove 111 that supplies connection plectane 32 to block towards the both ends of one side of filter 21, gu fixed ring 11 offers the rotation groove 112 that supplies spliced pole 31 and connection plectane 32 to block and rotate and be T shape in spread groove 111 lateral wall along circumference. The connection circular plate 32 of the connection post 31 is engaged into the connection groove 111, and then the filter plate 21 is rotated so that the connection circular plate 32 is rotated into the rotation groove 112, thereby fixing the filter plate 21 to the fixing ring 11.

As shown in fig. 3 and 4, the fixing ring 11 has two opposite inner walls at one end of the rotating groove 112 away from the connecting groove 111, the limiting groove 113 has a limiting post 33 with a circular cross section slidably connected in the limiting groove 113, one end of the limiting post 33 away from the bottom wall of the limiting groove 113 is hemispherical, and a fastening spring 34 is fixedly connected between the limiting post 33 and the bottom wall of the limiting groove 113. When the connecting column 31 is rotated to one end of the rotating groove 112, the limiting column 33 is extruded and retreated into the limiting groove 113, and after the connecting column 31 is rotated to one end of the rotating groove 112, the fastening spring 34 pushes the limiting column 33 out of the limiting groove 113, so that the connecting column 31 is limited to rotate freely in the rotating groove 112.

As shown in fig. 3, the fixing screw 211 of the filter screen 22 is penetrated and arranged by the both ends of one side of the filter plate 21 departing from the fixing ring 11, the clamping ring 212 for clamping the filter screen 22 is penetrated and arranged by the two fixing screw 211 together, one end of the fixing screw 211 is connected with the fixing nut 213 in a threaded manner, and the fixing screw 211 and the fixing nut 213 are made of PVC material, so as to avoid occurrence of corrosion. When a new filter screen 22 is replaced, the fixing nut 213 is unscrewed, the clamping ring 212 is taken off from the fixing screw rods 211, then the filter screen 22 is taken out, then the new filter screen 22 is replaced, the clamping ring 212 is sleeved on the two fixing screw rods 211, and the fixing nut 213 is screwed so that the clamping ring 212 clamps the filter screen 22, thereby fixing the filter screen 22 on the filter screen 21. The fixing screw 211 is sleeved with a spring washer 214 between the fixing nut 213 and the clamping plate. After the fixing nut 213 is tightened, the spring washer 214 can give a tension to the fixing nut 213, so that the pressure between the internal thread of the fixing nut 213 and the external thread of the fixing screw 211 is increased, and the friction therebetween is increased, thereby preventing the fixing nut 213 from loosening.

As shown in figure 6, the outer wall of the tube body 1 is close to one end of the filter plate 21 and is fixedly connected with a maintenance tube 4 with a circular cross section, the opening of the maintenance tube 4 is hinged with a sealing plate 5 with a circular shape, one side of the sealing plate 5 facing the inner cavity of the maintenance tube 4 is fixedly connected with a sealing block 51 with an outer wall tightly attached to the inner wall of the maintenance tube 4, and the sealing block 51 is made of silica gel, so that the tube has good deformability and corrosion resistance. The outer wall of the sealing block 51 is tightly attached to the inner wall of the maintenance pipe 4, so that the opening of the maintenance pipe 4 is sealed, and the sealing performance of the maintenance pipe 4 is further improved. The movable end of the sealing plate 5 is connected with the maintenance pipe 4 through a fixing piece 6. The mounting 6 includes the fixed arm 61 with closing plate 5 fixed connection, overhauls 4 outer walls of pipe and follows vertical direction fixedly connected with stop screw 62, sets up on the fixed arm 61 and supplies the fixed slot 611 that is the U-shaped that stop screw 62 card is gone into, and stop screw 62 one end threaded connection has stop nut 63, and stop nut 63 is the nut, makes things convenient for operating personnel bare-handed rotation stop nut 63. Open closing plate 5, in operating personnel stretched into body 1 through overhauing pipe 4 with the hand, rotated filter 21 and pulled down it, changed new filter screen 22, labour saving and time saving. After the replacement is completed, the sealing plate 5 is covered, the limit screw 62 is clamped into the fixing groove 611 on the fixing arm 61, and the limit nut 63 is screwed, so that the limit nut 63 abuts against the fixing arm 61, and the sealing plate 5 is fixed.

The working process is as follows:

firstly, the limit nut 63 is unscrewed, and the sealing plate 5 is opened; then, the filter plate 21 is rotated by extending into the maintenance tube 4 by hand, and the filter plate 21 is detached from the fixed ring 11; then, the fixing nut 213 is unscrewed, the clamping ring 212 is taken down, the filter screen 22 is taken down, a new filter screen 22 is sleeved on the fixing screw 211, the clamping ring 212 is sleeved on the fixing screw 211, and the fixing nut 213 is screwed; finally, the filter plate 21 is placed back into the tube body 1, the connecting circular plate 32 is clamped into the connecting groove 111, the filter plate 21 is rotated, the connecting column 31 and the connecting circular plate 32 are rotated into the rotating groove 112, the filter plate 21 is connected with the fixing ring 11, the sealing plate 5 is closed, the limiting nut 63 is screwed, and the filter screen 22 is replaced, so that time and labor are saved.
