[0015] A FRP tank cylinder lining forming process specifically includes the following steps:

[0016] 1. Clean the mold, spray the release agent, and heat the mold to 30-40℃ to improve the fluidity of the resin;

[0017] Second, adjust the formula as needed, then use a spray gun to spray the required materials onto the mold surface simultaneously to form a resin-rich layer, and then use a pressure roller to repeatedly roll it to eliminate bubbles and compact the fibers;

[0018] 3. First, ensure that the thickness of the lining layer is uniform and free of defects, and check for leakage at the seams;

[0019] 4. Place the FRP storage tank body horizontally according to the actual situation, and then start the first motor. Its output end will make the two first screws rotate synchronously through the linkage of the transmission gear and the driven gear. Then the first thread sleeve will cooperate with the triangle plate to interfere with the movement, so that the connecting plate moves horizontally on the surface of the first screw, which will cause the angle between the connecting arm and the connecting plate to become larger and larger, and finally the pad wheel on the main arm can be close to the inner wall surface of the FRP tank. Then, as the process needs, by starting the second motor, the transmission bevel gear and the driven bevel gear can drive the pad wheel to rotate, and finally the grinding rod will stay in the required position. Then, according to the required grinding thickness, the user needs to control the connecting arm. Extension length, during operation, the third motor can be started, and its output end drives the second screw to rotate. The opposite texture on the surface of the second screw will cause the second wire sleeve at the corresponding position on its surface to rotate accordingly, and then the sleeve will link the connecting frame to make the two turntables rotate in opposite directions. Finally, during this rotation process, the guide groove will cooperate with the limit groove to push the docking joint until it extends to the appropriate length. Then the user can control the operation of the second motor and the third motor in sequence, first through the first track sleeve and the second track sleeve to make the grinding rod turn to the required angle on the surface of the ball sleeve, and then start the first motor to start the grinding operation. Finally, the lining processing is completed after the grinding is completed;

[0020] 5. Control the connecting arm to retract and insert the block into the ventilation slot. Start the driver first to drive one docking shaft to rotate. Then, use the clamping block and sleeve to simultaneously control all docking shafts to rotate at the same angle until the slag retaining net is turned over. At this time, control the first motor to operate so that the vibration is transmitted to the slag retaining net until the attached grinding debris falls off and is cleaned up. Then, the machine can be controlled to leave the FRP tank.

[0021] Beneficial effects of the present invention:

[0022] Through the set retaining shell accessory structure, the user can place this device in the FRP tank cylinder and control its self-operation so that it can cooperate with the connecting arm accessory structure to extend and retract in conjunction to meet the processing requirements of the inner wall of the cylinder of different sizes, and the grinding direction of the grinding rod on the inner wall of the tank can be adjusted according to the process requirements to achieve the best processing effect. It can also cooperate with the self-cleaning of the slag retaining net when the grinding rod is in the retracted state, and can cooperate with the absorption of impurities generated by grinding in the extended state to reduce the workload of manual cleaning. It can also cooperate with the triangle plate accessory structure to further adapt to the inner wall diameter of the tank cylinder to control the grinding rod to move to the specified end for grinding operations, and can support the entire grinding process.

[0043] The present invention is a FRP tank cylinder lining forming process, which specifically includes the following steps:

[0044] 1. Clean the mold, spray the release agent, and heat the mold to 30-40℃ to improve the fluidity of the resin;

[0045] Second, adjust the formula as needed, then use a spray gun to spray the required materials onto the mold surface simultaneously to form a resin-rich layer, and then use a pressure roller to repeatedly roll it to eliminate bubbles and compact the fibers;

8. The FRP tank liner forming process according to any one of claims 1 to 7, characterized in that: The specific steps include:

1. Clean the mold, spray the release agent, and heat the mold to 30-40℃ to improve the fluidity of the resin; Second, adjust the formula as needed, then use a spray gun to spray the required materials onto the mold surface simultaneously to form a resin-rich layer, and then use a pressure roller to repeatedly roll it to eliminate bubbles and compact the fibers; 3. First, ensure that the thickness of the lining layer is uniform and free of defects, and check for leakage at the seams; 4. Place the FRP tank body horizontally according to the actual situation, then start the first motor (5), and its output end will make the two first screw rods (6) rotate synchronously through the linkage of the transmission gear (8) and the driven gear (9), and then the first thread sleeve (7) will cooperate with the triangular plate (1) to cause motion interference, so that the connecting plate (11) moves horizontally on the surface of the first screw rod (6), thereby causing the angle between the connecting arm (13) and the connecting plate (11) to become larger and larger, and finally the pad wheel (18) on the main arm (14) can be closely attached to the inner wall surface of the FRP tank, and then, as the process needs, by starting the second motor (15), the transmission bevel gear (16) can cooperate with the driven bevel gear (17) to drive the pad wheel (18) to rotate, and finally the grinding rod (42) can stay at the required position, and then according to the required grinding thickness, the user needs to control the extension and contraction of the connecting arm (35). The length of the output can be obtained by starting the third motor (23) during operation, and the output end thereof drives the second screw rod (34) to rotate. The opposite texture on the surface of the second screw rod (34) will cause the second wire sleeve (33) at the corresponding position on its surface to rotate accordingly, and then the sleeve (32) will link the connecting frame (31) to make the two turntables (27) rotate in opposite directions. Finally, during this rotation process, the guide groove (29) will cooperate with the limit groove (26) to push the docking joint (36) until it extends to a suitable length. Then, the user can control the operation of the second motor (43) and the third motor (47) in sequence, firstly through the first track sleeve (44) and the second track sleeve (48) to make the grinding rod (42) turn to the required angle on the surface of the sleeve ball (39), and then start the first motor (38) to carry out the grinding operation. Finally, the lining processing can be completed after the grinding is completed.

5. Control the connecting arm (35) to retract and insert the blocking block (52) into the ventilation slot (51). First, start the driver to drive a docking shaft (55) to rotate. Then, through the clamping block (57) and the sleeve (58), all docking shafts (55) are controlled to rotate at the same angle until the slag blocking net (56) is turned over. At this time, control the first motor (38) to operate so that the vibration is transmitted to the slag blocking net (56) until the attached grinding debris falls off and is cleaned up. Then, the machine can be controlled to leave the FRP storage tank.
