When the special tool is used for dismantling the reverse osmosis membrane, firstly, two semi-annular cuffs 4 are sleeved on a bell mouth 2, the two semi-annular cuffs 4 are fixed by a connecting bolt 5, then a binding band 8 bypasses a vertical pipe 3 and penetrates through a gap between a convex block 6 and a pressing plate 10, after the distance position of the semi-annular cuffs 4 on the bell mouth 2 relative to the vertical pipe 3 is adjusted, a butterfly bolt 9 is rotated to enable the pressing plate 10 to tightly press and position the binding band 8 on the convex block 6, after the operation is finished, the front end of a first ball screw rod 18 with a ball screw nut 19 is penetrated into a rotary sleeve 15 and a through hole 13 of a screw rod jacking device, a plug 35 at the front end of the first ball screw rod 18 is inserted into a plug-in groove 22 of a circular plate 23, the ball screw rod 18 and the circular plate 23 are conveyed into the bell mouth 2, and then a fixing plate 11 is installed on a connecting screw rod 7 by a connecting nut 12, the ball screw 18 is moved forwards until the inserted link 24 at the front end of the circular plate 23 is matched with the reverse osmosis membrane, then the ball screw nut 19 is rotated to enter the rotary sleeve 15, the positioning pin 21 is inserted into the positioning long hole 20, the ball screw nut 19 and the rotary sleeve 15 are integrated and can synchronously rotate, finally the worm 17 is rotated to drive the turbine 16 and the rotary sleeve 15 to rotate, because the ball screw 18 is limited by rotation, the ball screw 18 can gradually extend into the water-cooling purification pipe 1, according to the length requirement for dismantling the reverse osmosis membrane, the ball screw 18 is connected end to form a whole, the whole is sent to the water-cooling purification pipe 1, and the ejection operation of each reverse osmosis membrane is completed.
Further, in order to ensure that the binding band 8 is positioned between the pressing plate 10 and the projection 6 in a compressed manner, as shown in fig. 9, the pressing plate 10 and the projection 6 are provided with friction protrusions 31 on their respective sides.
Furthermore, the binding band 8 is a nylon binding band which has excellent wear resistance, stable size, small shrinkage and certain ductility, and has certain elastic allowance and relatively long service life when the semi-annular hoop 4 and the vertical tube 3 are fixedly connected.
Furthermore, in order to rotate the worm 17 more laborsavingly when the single person operates, one end of the worm 17 is mounted on the fixing plate 11 through the bearing seat 32, the other end of the worm 17 is mounted with the rotating handle 33, and the arrangement of the rotating handle 33 effectively increases the arm of force for operating rotation, thereby playing a labor-saving role.
Further, in order to avoid the rotation of the ball screw 18 before the ball screw 18 drives the disc 23 to advance and not contact with the reverse osmosis membrane, the friction rubber pad 34 is installed on the roller 26, the friction force between the roller 26 and the inner wall of the water-cooling purification tube 1 can be increased by the arrangement of the friction rubber pad 34, the disc 23 is prevented from rotating, meanwhile, the friction rubber pad 34 cannot block the rotation of the roller 26, and the disc 23 can move along the length direction of the water-cooling purification tube 1 and eject out the internal reverse osmosis membrane.
The positioning between the positioning pin 21 and the ball screw nut 19 can be realized by setting a screw hole matched with the positioning pin 21 on the rotary sleeve 15, and the positioning pin 21 can extend into the positioning long hole 20 on the ball screw nut 19 by rotating, so that the purpose of synchronous rotation of the ball screw nut 19 and the rotary sleeve 15 is realized. Further, in order to save the manual operation of rotating the positioning pin 21, as shown in fig. 10, a through hole matched with the positioning pin 21 is formed in the rotary sleeve 15, a convex edge 38 is installed on the periphery of the positioning pin 21, a second spring 39 is sleeved on the periphery of the positioning pin 21 above the convex edge 38, and the second spring 39 always tends to make the positioning pin 21 penetrate through the through hole and enter the rotary sleeve 15. Before the ball screw nut 19 enters the rotary sleeve 15, the positioning pin 21 can be manually pulled up against the elastic force of the second spring 39, once the ball screw nut 19 enters the rotary sleeve 15, as long as the positioning long hole 20 moves to the position of the positioning pin 21, under the elastic force action of the second spring 39, the positioning pin 21 can extend into the positioning long hole 20, the ball screw nut 19 is locked, and the ball screw nut 19 and the rotary sleeve 15 can synchronously rotate.
Further, in order to facilitate the electric removal of the permeable membrane, an electric removal auxiliary device is installed on the worm 17, as shown in fig. 11, the electric removal auxiliary device includes a first gear 40 installed at one end of the worm 17, a second gear 41 engaged with the first gear 40 is installed on the fixing plate 11, wherein the diameter of the first gear 40 is larger than that of the second gear 41, a rotating nut 42 is further installed at a central position of an outer side surface of the second gear 41, and the rotating nut 42 can drive the rotating sleeve 15 to rotate sequentially through the second gear 41, the first gear 40, the worm 17 and the turbine 16 when rotating. The electric dismantling auxiliary device can use the existing electric nut tightening machine as power to drive the rotating nut 42 in a matching way, and the connecting nut 12 matched with the connecting screw 7 can also be installed by using the electric nut tightening machine to replace manual work to complete feeding of the ball screw 18 and dismantling of the permeable membrane. The large diameter second gear 41 provides a greater torque during rotation and the use of the power nut runner also reduces the labor intensity of the operator to some extent.
When the permeable membrane removing work is performed by using the above-mentioned special tool, if the rotary sleeve 15 is continuously rotated without connecting the next ball screw 18, the ball screw 18 inserted into the water-cooled purge tube 1 is separated from the ball screw nut 19, and if the subsequent ball screw 18 is not additionally connected, the balls in the ball screw nut 19 are dropped, so that the ball screw 18 cannot be normally driven to advance. In order to avoid the above situation, the fixing plate 11 is provided with the automatic ball screw nut withdrawing device, if there is no ball screw 18 to continue to connect, the ball screw nut 19 can be separated from the rotary sleeve 15, even if the rotary sleeve 15 is rotated, the ball screw nut 19 can not rotate along with the rotary sleeve 15, the ball screw 18 inside the ball screw nut can not continue to advance, and can not be separated from the ball screw nut 19, so as to ensure the normal operation of the subsequent operation.
As shown in fig. 12, the automatic ball screw nut withdrawing device includes three sets of brackets 43 mounted on the fixing plate 11, a swing rod 44 is hinged to each set of brackets 43, a limiting wheel 45 is mounted at the end of the swing rod 44, and a torsion spring 46 is mounted between the swing rod 44 and the brackets 43, wherein the torsion spring 46 always tends to make the limiting wheel 45 rotate and approach. The positioning long hole 20 is opened to the front end surface of the ball screw nut 19, a thrust bearing 47 is mounted on the rear end surface of the ball screw nut 19, and when the retainer wheel 45 is located on the outer periphery of the ball screw 18, as shown in fig. 13, the retainer wheel 45 is in contact with the thrust bearing 47, and the ball screw nut 19 is always located in the rotary sleeve 15. As shown in fig. 14, when one ball screw 18 enters the ball screw nut 19 and is no longer in contact with the retainer wheel 45, the retainer wheel 45 rotates and separates from the thrust bearing 47 under the action of the torsion spring 46, and the rotation of the rotary sleeve 15 causes the ball screw nut 19 to rotate on the ball screw 18 and separate from the rotary sleeve 15.
In the state shown in fig. 13, due to the existence of the ball screw 18, the limiting wheels 45 will overcome the elastic force of the torsion spring 46 to move away from each other and press against the ball screw 18 to form a lifting location for the ball screw 18, the limiting wheels 45 in this state contact with the thrust bearing 47 to form a limiting for the ball screw nut 19, and the ball screw nut 19 will not move to the right in the state shown in fig. 13, that is, the ball screw nut 19 is always located in the rotary sleeve 15 and rotates along with it.
If another ball screw 18 is not connected, the rotating sleeve 15 continues to be rotated to drive the ball screw 18 to move to the state shown in fig. 14, the ball screw 18 is separated from the limiting wheel 45, the limiting wheel 45 is reset to the state of being close to each other under the elastic force of the torsion spring 46, the limitation on the thrust bearing 47 is lost, and if the rotating sleeve 15 continues to be rotated, the ball screw nut 19 which is not limited by the right movement rotates to the right due to the resistance of the ball screw 18, until the positioning pin 21 is separated from the positioning long hole 20, the ball screw nut 19 is separated from the rotating sleeve 15, and when the rotating sleeve 15 rotates, the ball screw nut 19 cannot rotate along with the ball screw nut 18, the ball screw 18 cannot move relative to the ball screw nut 19, and the situation that the ball screw nut 19 is separated from the ball screw 18 cannot occur.
Further, in order to reduce the friction between the positioning pin 21 and the long positioning hole 20 to the maximum when the ball screw nut 19 is separated from the rotary sleeve 15, the rolling bearing 48 is mounted at the bottom of the positioning pin 21 located in the long positioning hole 20, and the arrangement of the rolling bearing 48 converts the sliding friction between the positioning pin 21 and the long positioning hole 20 into rolling friction, so that the friction between the movement of each other is reduced, and the service life of the positioning pin 21 and the long positioning hole 20 is effectively prolonged.
