[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] See also Figure 1-4 The utility model provides an embodiment of a pressure vessel spraying device, comprising a spraying device 1, a material taking-in and discharging opening 101 is provided at the front end of the spraying device 1, a support platform 102 is fixedly provided in the middle of the lower end of the spraying device 1, a pressure vessel 103 is placed on the support platform 102, support columns 2 are fixedly provided in the middle of the end surfaces on both sides of the interior of the spraying device 1, a lifting groove 201 is provided on the upper end of one side of the support column 2, a lifting plate 3 is provided between the lifting grooves 201 of the two support columns 2, both sides of the lifting plate 3 are fixedly connected to the limiting plate 301, and a C-shaped connecting rod 302 is fixedly provided in the middle of the upper end of the lifting plate 3 A hydraulic rod 104 for driving the lifting plate 3 to rise and fall is fixedly provided at the upper end of the spraying device 1, and a transmission box 4 is fixedly provided in the middle of the lower end of the lifting plate 3. A rotary joint 401 is fixedly provided at the upper end of the transmission box 4, and the upper end of the rotary joint 401 is fixedly connected to the feed pipe 402, and the lower end of the rotary joint 401 is fixedly connected to the hard main conveying pipe 5, and the lower end of the hard main conveying pipe 5 extends out of the transmission box 4 and is fixedly connected to a C-type hard conveying pipe 502. A plurality of nozzles 503 are fixedly connected to both sides of the inner side of the C-type hard conveying pipe 502, and a circular sealing plate 6 is rotatably connected to the middle of the upper end of the inner side of the C-type hard conveying pipe 502.

[0024] Furthermore, a guide rod 202 is fixedly provided in the middle of the lifting groove 201, and the limit plates 301 on both sides of the lifting plate 3 are respectively inserted into the two lifting grooves 201 and the middle of the guide rod 202 passes through the middle of the limit plate 301. The limit plate 301 is guided to rise and fall in the lifting groove 201 by the two guide rods 202, so that the lifting plate 3 remains stable through the limit plate 301 when it is raised and lowered.

[0025] Furthermore, the telescopic end of the lower end of the hydraulic rod 104 extends to the inside of the spraying device 1 and is fixedly connected to the middle part of the upper end of the C-shaped connecting rod 302. The hydraulic rod 104 drives the lifting plate 3 to rise and fall. When the pressure vessel 103 is ready to spray, the hydraulic rod 104 drives the lifting plate 3 to descend, and the C-shaped hard conveying pipe 502 follows the descent, so that the circular sealing plate 6 rotatably connected to the lower end of the C-shaped hard conveying pipe 502 is sealed with the upper end opening of the pressure vessel 103 to prevent the spraying raw materials from entering the interior of the pressure vessel 103 from the upper end opening and causing pollution.

[0026] Furthermore, the upper end of the feed pipe 402 extends out of the interior of the spray device 1 and is connected to the storage box of the spray raw material through a booster pump. The booster pump pressurizes the spray raw material and delivers it to the hard main delivery pipe 5 through the feed pipe 402. The hard main delivery pipe 5 delivers the spray raw material to the C-type hard delivery pipe 502. When the C-type hard delivery pipe 502 rotates, the side end face of the pressure vessel 103 is sprayed through multiple nozzles 503.

[0027] Furthermore, the upper end of the hard main delivery pipe 5 is fixedly connected to a turbine 501 inside the transmission box 4 .

[0028] Furthermore, a motor 403 is provided inside the transmission box 4, and a worm 404 is fixedly connected to the output shaft of the motor 403. The worm 404 is engaged with the teeth of the turbine 501. The motor 403 drives the worm 404 to rotate, and then drives the hard main conveying pipe 5 to rotate at the lower end of the rotary joint 401, so that the C-shaped hard conveying pipe 502 can rotate.

[0029] Furthermore, the upper end of the circular sealing plate 6 is rotatably connected to the C-shaped rigid conveying pipe 502 via a rotating shaft 601, so that after the circular sealing plate 6 closes the upper end opening of the pressure vessel 103, the C-shaped rigid conveying pipe 502 can rotate.

[0030] Working principle: During use, when it is necessary to spray the pressure vessel 103, first ensure that the pressure vessel 103 has been placed on the support platform 102, and close the spraying device 1 through the material access opening 101. Subsequently, start the hydraulic rod 104, and its telescopic end pushes the C-shaped connecting rod 302 downward, thereby driving the lifting plate 3 and all components thereon to descend along the lifting groove 201. During the descent, the two guide rods 202 pass through the middle of the limit plate 301 to ensure the smooth descent of the lifting plate 3. When the lifting plate 3 descends to the appropriate position, the circular sealing plate 6 at the lower end of the C-shaped hard conveying pipe 502 will be close to the upper end opening of the pressure vessel 103. The circular sealing plate 6 can achieve effective sealing of the upper end opening of the pressure vessel 103, thereby preventing the spraying raw materials from entering the interior of the pressure vessel 103 from the opening and causing contamination. At the same time, the spraying material is pressurized by the booster pump from the storage box, enters the rotary joint 401 through the feed pipe 402, and is then transported to the C-type hard delivery pipe 502 through the hard main delivery pipe 5. At this time, the motor 403 in the transmission box 4 is started, and the motor 403 drives the worm 404 to rotate. The meshing transmission of the worm 404 and the turbine 501 causes the hard main delivery pipe 5 and the C-type hard delivery pipe 502 to start rotating as a whole. As the C-type hard delivery pipe 502 rotates, the multiple nozzles 503 fixedly connected thereto begin to evenly spray the side end face of the pressure vessel 103. Due to the effective closure of the circular sealing plate 6, the spraying material is confined to the outside of the pressure vessel 103, ensuring the cleanliness and efficiency of the spraying process.

[0031] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
