Description

Technical Field

[0001] The present invention relates to the technical field of container processing, and in particular to processing equipment for chemical pressure containers. Background Art

[0002] Chemical pressure vessels are used to store and transport chemical products, such as liquids and gases, and are widely used in industries such as petrochemicals, pharmaceuticals, and food processing. These tanks are typically constructed of metals like steel, with smooth, flat interiors, offering both corrosion resistance and high strength. Welding equipment can weld components together to ensure pressure resistance, corrosion resistance, and a leak-proof seal. Submerged arc, gas shielded, and resistance welding techniques can be used to ensure weld quality and safety, meeting operational requirements.

[0003] In the processing equipment of a chemical pressure vessel disclosed in the patent publication number "CN118321691B", a measuring rod is fitted and slid with one side of two chemical containers to control and adjust the amount of welding flux discharged from the buried material port on the submerged arc welding gun, and the welding head adjusts the welding power at the same time. Although it can prevent the situation where the gap between the chemical containers is too small or too large during welding, which causes waste of welding flux due to excessive discharge, and reduces the welding quality when the discharge is small, in actual use, burrs on the welding contact surface of the container before welding will directly affect the welding effect, resulting in defects such as unevenness and inclusions in the weld. In addition, after the welding is completed, the welding slag, spatter and welding additives that have not been completely volatilized left on the surface of the container will greatly affect the appearance and neatness of the container.

[0004] Based on this, the present application proposes a processing equipment for chemical pressure vessels. Summary of the Invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a processing equipment for chemical pressure vessels.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0015] Preferably, the processing table is provided with four mounting grooves, in which cylinders are fixedly mounted respectively, and the four cylinder output shafts are fixed in pairs under two mounting seats respectively.

[0016] The present invention has the following beneficial effects:

[0017] 1.

When the rack is reset, it will drive the piston to generate negative pressure in the piston cylinder. Under the action of the one-way valve, the water in the water tank enters the piston cylinder to prepare for the next cooling. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described 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.

[0028] Example 1:

[0029] Reference Figure 1-4 , a processing equipment for chemical pressure vessels, comprising a processing table 1, two grinding components and two cooling components;

[0030] Two baffles 5 are fixedly connected to the processing table 1, and the two baffles 5 are respectively slidably connected to the mounting seats 6. The two mounting seats 6 are respectively rotatably connected to a plurality of first rollers 9 for rotating the container storage tank 2. A notch 7 is provided on the processing table 1, and a plurality of second rollers 13 are rotatably connected in the notch 7. Two container storage tanks 2 are provided above the plurality of second rollers 13. The two container storage tanks 2 are respectively placed on the plurality of first rollers 9. In this way, the container storage tank 2 can rotate on the first roller 9. The two mounting seats 6 are respectively provided with a first chute 4. Two first brackets 21 are slidably connected in the two first chute 4. The first bracket 21 can slide in the first chute 4 and can also rotate with the mounting seat. The mounting seat 6 is raised and lowered, and a second slide groove 26 is provided on the first bracket 21. A rack 20 is slidably connected in the second slide groove 26. An electric telescopic rod 27 is fixedly installed in the second slide groove 26. The output shaft of the electric telescopic rod 27 is fixedly connected to the rack 20. The rack 20 can be controlled to slide in the second slide groove 26 through the electric telescopic rod 27. Four mounting grooves 16 are provided on the processing table 1. Cylinders 17 are fixedly installed in the four mounting grooves 16 respectively. The output shafts of the four cylinders 17 are fixed in pairs under the two mounting seats 6. The mounting seat 6 can be driven up and down by the cylinder 17, so that the container tank 2 is placed on the second roller 13, and then the container tank 2 can be pushed to move laterally on it.

[0031] The grinding assembly is used to grind the inner wall and welding contact surface of the container tank 2. The grinding assembly consists of a mounting block 14, a first grinding wheel 15 and a first gear 18. The mounting block 14 is rotatably connected to the first bracket 21, and the first grinding wheel 15 is rotatably connected to the mounting block 14. A motor is provided in the mounting block 14 for driving the first grinding wheel 15 to rotate. The first gear 18 is fixedly connected in the mounting block 14. The first gear 18 is meshed with the rack 20. When the rack 20 slides, it can drive the first gear 18 to rotate, so that the first gear 18 drives the mounting block 14 to rotate, so that the grinding surface of the first grinding wheel 15 is attached to the inner wall or welding contact surface of the container tank 2.

[0032] In this embodiment, after the container tank 2 is placed on the first roller 9, the cylinder 17 drives the mounting seat 6 and the first bracket 21 to descend, so that the container tank 2 is lowered and placed on the second roller 13, and then the container tank 2 is pushed onto the first bracket 21, and then the mounting seat 6 is raised, and the electric telescopic rod 27 is started to make the rack 20 drive the first gear 18 to rotate, so that the first grinding wheel 15 on the mounting block 14 is attached to the welding contact surface of the container tank 2 to grind and polish it, so as to avoid burrs, rust and other impurities on the welding contact surface from adversely affecting the subsequent welding quality.

[0033] Example 2:

[0034] The difference from the first embodiment is that, referring to Figure 2 - Figure 4 , this embodiment also has the following further contents:

[0035] A mounting bracket 28 is fixedly mounted on the processing table 1, and a welding device 8 is fixedly mounted on the mounting bracket 28 for welding two container tanks 2. The first bracket 21 is rotatably connected to the second bracket 3, and the second bracket 3 is rotatably connected to the second grinding wheel 12. A motor for driving the second grinding wheel 12 to rotate is provided in the second bracket 3. A second gear 19 is fixedly connected to the second bracket 3, and the rack 20 is meshed with the second gear 19. When the rack 20 slides, it can drive the second gear 19 to rotate, so that the second gear 19 drives the second bracket 3 to rotate, so that the second grinding wheel 12 on the second bracket 3 is attached to the weld on the outer side of the container tank 2.

[0036] In this embodiment, the two mounting seats 6 are driven to descend again by the cylinder 17, so that the two container tanks 2 are lowered on the second roller 13, and then the two container tanks 2 are pushed to the welding equipment 8 for welding, and the rack 20 is driven by the electric telescopic rod 27 to rotate the first gear 18 and the second gear 19. The first gear 18 makes the grinding surface of the first grinding wheel 15 on the mounting block 14 face upward, and at the same time, the second gear 19 makes the second bracket 3 drive the second grinding wheel 12 with the grinding surface facing downward, and the first bracket 21 is pushed into the container tank 2, and the welds on the inner and outer walls of the container tank 2 are respectively polished and polished by the first grinding wheel 15 and the second grinding wheel 12, thereby avoiding the problems of roughness and residual impurities in the welds affecting the appearance of the container tank 2.

[0037] Example 3:

[0038] Reference Figure 3 - Figure 4 Compared with the first and second embodiments, in this embodiment:

[0039] A water tank 24 is fixedly connected to the first bracket 21 , and a water inlet pipe 22 is connected to the water tank 24 . Water in the water tank 24 can enter the piston cylinder 10 through the water inlet pipe 22 .

[0040] The cooling assembly is used to cool the weld on the container tank 2. The cooling assembly consists of a piston cylinder 10, a water outlet pipe 11, a piston 25 and a piston rod 23. The piston cylinder 10 is connected to the water inlet pipe 22, and the water outlet pipe 11 is connected to the piston cylinder 10. The cooling water squeezed in the piston cylinder 10 can be guided out and sprayed onto the weld of the container tank 2 to achieve cooling. The piston 25 is slidably connected to the inner wall of the piston cylinder 10, and the piston rod 23 is slidably connected to the piston cylinder 10. The piston cylinder 10 and the outlet pipe are connected to each other. A one-way valve is provided at the connection point between the water pipe 11 and the water inlet pipe 22. The one-way valve at the water inlet pipe 22 ensures that water can only flow into the piston cylinder 10 in one direction, preventing the water in the cylinder from flowing back to the water source, while the one-way valve at the water outlet pipe 11 ensures that the squeezed water can only flow out from the water outlet pipe 11, directional acting on the weld cooling of the container storage tank 2. One end of the piston rod 23 is fixedly connected to the piston 25, and the other end is fixedly connected to the rack 20. The rack 20 can enable the piston rod 23 to drive the piston 25 to reciprocate in the piston cylinder 10.

[0041] In this embodiment, after the welding of the container storage tank 2 is completed, the electric telescopic rod 27 drives the rack 20 to slide, and the rack 20 drives the piston rod 23 to make the piston 25 generate positive pressure in the piston cylinder 10. Under the action of the one-way valve, the water in the piston cylinder 10 is only sprayed out from the water outlet pipe 11 to cool the weld on the container storage tank 2, thereby avoiding the generation of thermal cracks in the weld due to long-term high temperature, and ensuring the strength and toughness of the weld. When the rack 20 is reset, it will drive the piston 25 to generate negative pressure in the piston cylinder 10. Under the action of the one-way valve, the water in the water tank 24 enters the piston cylinder 10 to prepare for the next cooling.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
