[0002] With the rapid development of the petrochemical industry, the requirements for corrosion protection construction of petrochemical pressure vessels have also increased. However, existing corrosion protection construction still has certain quality problems in the coating spraying process. For example, the existing spraying structure has the problem of uneven spraying during the coating process, resulting in low spraying quality and efficiency, which greatly affects the normal corrosion protection quality of petrochemical pressure vessels. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies and to propose a corrosion protection construction device for petrochemical pressure vessels, which can improve the uniformity of coating spraying and effectively ensure the quality and efficiency of spraying.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A corrosion protection construction device for petrochemical pressure vessels includes a base plate, on which an mounting plate is installed via a height adjustment assembly. A paint storage tank is fixedly connected to the mounting plate. A water pump is fixedly connected to the outer side of the paint storage tank, with the inlet end of the water pump communicating with the interior of the paint storage tank and the outlet end of the water pump fixedly connected to an elastic telescopic pipe. A transmission box is installed on the mounting plate. A transmission pipe is installed inside the transmission box, with one end of the elastic telescopic pipe penetrating one side wall of the transmission box and communicating with one side of the transmission pipe. A connecting pipe is fixedly connected to the other side of the transmission pipe, penetrating the other side of the transmission box and fixedly connected to an arc-shaped spraying pipe. A spray head is fixedly connected to the inner side of the spraying pipe. One end of the transmission pipe is fixedly connected to the inner wall of one end of the transmission box via a connecting plate and a return spring, and the other end penetrates the other end of the transmission box via a middle rod and is fixedly connected to a force-bearing frustum. A drive motor located below the force-bearing frustum is also fixedly installed on the mounting plate, with a force-applying cam fixedly connected to the output end of the drive motor located on one side of the force-bearing frustum.

[0006] Furthermore, the height adjustment assembly includes a mounting U-shaped plate and an electric push rod fixedly connected to the base plate. The electric push rod is located inside the mounting U-shaped plate, and its top end passes through the mounting U-shaped plate and is fixedly connected to the mounting plate.

[0007] Furthermore, two directional tubes located on both sides of the electric push rod are fixedly connected to the base plate. A directional rod is slidably connected to the inner wall of the directional tube through a directional piston. The top of the directional rod is fixedly connected to the mounting plate.

[0008] Furthermore, two limiting grooves are provided on the inner wall of the bottom of the transmission box, located on both sides of the transmission pipe. The two sides of the transmission pipe are slidably connected to the limiting grooves by limiting rods, which improves the stability of the transmission pipe.

[0009] Furthermore, a stirring motor is fixedly connected to the top of the paint storage tank, and a rotating rod is fixedly connected to the output end of the stirring motor. The bottom end of the rotating rod penetrates the top wall of the paint storage tank. Stirring rods located inside the paint storage tank are fixedly connected to both sides of the rotating rod. Mounting tubes at the same horizontal plane as the stirring rods are fixedly connected to the inner walls of both sides of the paint storage tank. A sealing piston is fixedly connected to the inner wall of the mounting tube by a telescopic spring. A transmission frustum is fixedly connected to the side of the sealing piston near the rotating rod. Baffles are fixedly connected to the upper and lower surfaces of the transmission frustum.

[0010] Furthermore, the top of the paint storage tank is equipped with an addition pipe for adding paint.

[0011] Furthermore, the top of the transmission box is open.

[0012] Furthermore, the bottom of the base plate is equipped with movable rollers for easy movement.

[0013] Furthermore, a push handle is fixedly connected to one side of the base plate for easy operation.

[0014] Furthermore, the number of the return springs is no less than five.

[0015] Technical effects of this utility model:

[0016] Compared with existing technologies, the present invention provides an anti-corrosion construction device for petrochemical pressure vessels. The drive motor controls the rotation of a force-applying cam, which intermittently applies pressure to a force-bearing frustum. This intermittent pressure causes the transmission pipe to reciprocate in the forward and backward direction under the action of a return spring. This reciprocating movement of the transmission pipe pulls the spraying pipe and spray head to reciprocate in the forward and backward direction. Furthermore, by causing the spraying structure to undergo high-frequency reciprocating motion during the spraying process, the spraying becomes more uniform, thereby improving the quality and efficiency of the spraying process.

[0027] The paint storage tank 9 is fixedly connected to the top of the mounting plate 6. An adding pipe 10 is provided on the top of the paint storage tank 9. A water pump 11 is fixedly connected to the front of the paint storage tank 9. An inlet pipe 12 is fixedly connected to the bottom of the water pump 11. The inlet pipe 12 is L-shaped, and its horizontal part at the bottom passes through the lower end of the front of the paint storage tank 9 and extends to the bottom of the paint storage tank 9. An elastic telescopic pipe 13 is fixedly connected to the right end of the water pump 11.

[0028] The transmission box 14 is fixedly connected to the top of the mounting plate 6 via a connecting rod, located on the right side of the paint storage box 9. The top of the transmission box 14 is open, and a transmission pipe 15 is provided inside the transmission box 14. Both ends of the transmission pipe 15 are closed. The right end of the elastic telescopic pipe 13 passes through the left wall of the transmission box 14 and communicates with the transmission pipe 15. Two limiting grooves 18 are opened on the inner wall of the bottom of the transmission box 14, located on both sides of the transmission pipe 15. The two sides of the transmission pipe 15 are slidably connected to the inner surface of the limiting grooves 18 via limiting rods 19. The right side of the transmission pipe 15 passes through the right wall of the transmission box 14 via a connecting pipe and is fixedly connected to an arc-shaped spray pipe 20. A spray head 21 is fixedly connected to the right side of the spray pipe 20. The right side of the transmission box 14 is open. The transmission pipe 15 is provided with a chute that allows the connecting pipe to reciprocate along its length. The number of spray heads 21 is not less than thirteen. One end of the back of the transmission pipe 15 is fixedly connected to the inner wall of the back of the transmission box 14 via a connecting plate 16 and a return spring 17. The number of return springs 17 is not less than five. One end of the front of the transmission pipe 15 passes through the front of the transmission box 14 via a middle rod and is fixedly connected to a force-bearing frustum 22. The top of the mounting plate 6 is fixedly connected to a drive motor 23 located below the force-bearing frustum 22 via a support rod. A force-applying cam 24 located on the left side of the force-bearing frustum 22 is fixedly connected to the output end of the front of the drive motor 23.

[0029] A stirring motor 26 is fixedly connected to the top of the paint storage tank 9. A rotating rod 27 is fixedly connected to the output end of the bottom of the stirring motor 26. The bottom end of the rotating rod 27 penetrates the top wall of the paint storage tank 9. Stirring rods 28 located inside the paint storage tank 9 are fixedly connected to both sides of the rotating rod 27. Mounting tubes 29, which are at the same level as the stirring rods 28, are fixedly connected to the inner walls of both sides of the paint storage tank 9. A sealing piston 31 is fixedly connected to the inner wall of the mounting tube 29 by a telescopic spring 30. A transmission frustum 32 located on the back of the stirring rod 28 is fixedly connected to the side of the sealing piston 31 near the rotating rod 27. Baffles 33 are fixedly connected to the upper and lower surfaces of the transmission frustum 32. There are no fewer than six stirring rods 28 and no fewer than six transmission frustums 32.

[0030] The working principle of this utility model is as follows: by starting the water pump 11, the paint in the paint storage tank 9 is extracted by the liquid inlet pipe 12 and transferred to the elastic telescopic pipe 13. The elastic telescopic pipe 13 transfers the paint to the spraying pipe 20 through the transmission pipe 15. The paint in the spraying pipe 20 is sprayed out through the spray head 21, and then the spraying work is carried out. This invention utilizes the starting of the stirring motor 26 to control the rotation of the stirring rod 28 via the rotating rod 27. The rotation of the stirring rod 28 intermittently applies pressure to the transmission platform 32 while simultaneously stirring the paint. This intermittent pressure, combined with the action of the telescopic spring 30, causes the baffle plate 33 to reciprocate at a high frequency. This high-frequency reciprocating motion of the baffle plate 33, in conjunction with the rotation of the stirring rod 28, improves the quality and efficiency of paint stirring, thereby enhancing the quality of paint spraying. The water pump 11 then draws paint from the paint storage tank 9 through the inlet pipe 12 and transfers it to the elastic telescopic pipe 13. The elastic telescopic pipe 13 then transfers the paint through the transmission pipe 15 to the spraying pipe 20. The paint inside the nozzle 21 is sprayed out to perform the spraying work. The drive motor 23 is started to control the force-applying cam 24 to rotate. The rotation of the force-applying cam 24 intermittently applies force to the force-receiving truncated cone 22. The force-receiving truncated cone 22 is intermittently subjected to force, causing the transmission pipe 15 to reciprocate along the length of the transmission pipe 15 under the action of the return spring 17 (the elastic telescopic pipe 13 can extend and retract, ensuring the smooth reciprocating movement of the transmission pipe 15). The reciprocating movement of the transmission pipe 15 pulls the spraying pipe 20 and the spraying head 21 to reciprocate along the length of the transmission pipe 15. In this way, by making the spraying structure reciprocate at a high frequency during the spraying process, the spraying is more uniform, thereby improving the spraying quality and efficiency.
