Description
Technical Field
[0001] The utility model relates to the technical field of stainless steel pipe production, in particular to a wet-dry separation device for water polishing of stainless steel pipe welding joints. Background Art
[0002] Stainless steel pipes are produced and processed from stainless steel strips. When the stainless steel strips are bent, the butt joints are welded to form round pipes to achieve overall forming. When producing stainless steel pipes, the weld joints need to be polished smoothly to ensure good appearance and product quality. When polishing, water or cutting fluid needs to be sprayed on the contact part between the polishing wheel and the steel pipe.
[0003] In the prior art, the excess water or cutting fluid sprayed will flow downward and directly flow into the water receiving tank on the ground for collection, filtration and reuse. However, since the stainless steel pipe production workshop belongs to a rough processing workshop with low cleanliness, when the open water receiving tank recovers the polishing water or cutting fluid, it is not only easy to be mixed with too much dust, but also easy to splash water and cutting fluid, causing the ground around the production line to be wet and the equipment to rust. There are defects, so a wet-dry separation device for water polishing of stainless steel pipe welding joints is proposed. Summary of the Utility Model
[0004] Aiming at the deficiencies of the prior art, the utility model provides a wet-dry separation device for water polishing of stainless steel pipe welding joints, which is used to solve the problems of poor recovery effect of water or cutting fluid used for grinding at the weld joint station of the stainless steel pipe production line, resulting in dust inclusion, wetting the surrounding ground and corroding the equipment.
[0005] To solve the above technical problems, the utility model provides the following technical solutions:
[0006] A wet-dry separation device for water polishing of stainless steel pipe welding joints includes a deepened water tank with an open top, which is arranged outside the polishing wheel, supporting wheel and steel pipe. The front and back of the deepened water tank are provided with relief holes corresponding to the rotating shafts of the polishing wheel and the supporting wheel. The two sides of the deepened water tank are provided with through holes corresponding to the steel pipe. A dripping wiping block in contact with the top weld joint of the steel pipe is arranged at a position upstream of the polishing wheel in the deepened water tank. An outlet pipe connected to the water inlet pipe is arranged between the dripping wiping block and the polishing wheel. The outlet of the outlet pipe extends above the polishing wheel and the dripping wiping block respectively. A cover plate is arranged above the deepened water tank, and a relief groove corresponding to the water inlet pipe is arranged at the position of the cover plate.
[0007] An installation groove one is arranged on the inner wall of the downstream side corresponding to the deepened water tank. A wiping block one sleeved on the surface of the steel pipe is installed in the installation groove one. A through hole corresponding to the steel pipe is also arranged on the installation groove one. A water leakage hole one is arranged at the bottom of the installation groove one.
[0008] On the outer side of the downstream of the deepened water tank, there is a second installation groove. A second water wiping block sleeved on the surface of the steel pipe is installed in the second installation groove. Through holes are also provided at positions corresponding to the steel pipe on both sides of the second installation groove. A second water leakage hole and a connecting pipe communicating with the deepened water tank are provided at the bottom of the second installation groove.
[0009] Preferably, the steel pipe is located in the middle of the deepened water tank, and the distance between the polishing wheel and the inner wall of the corresponding upstream side of the deepened water tank is less than the distance between the polishing wheel and the inner wall of the corresponding downstream side of the deepened water tank.
[0010] Preferably, there are two cover plates located on both sides of the water inlet pipe respectively. The side of the cover plate away from the water inlet pipe is movably hinged to the deepened water tank, and a turning handle is provided on the cover plate.
[0011] Preferably, the dripping water wiping block is installed in the deepened water tank through a fixing clip, and clamping grooves for clamping the fixing clip are provided on the front and back of the inner wall of the deepened water tank.
[0012] Preferably, the second installation groove is installed on the side of the deepened water tank through a connecting frame, and the distance between the second installation groove and the deepened water tank is not less than 20 cm.
[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] 1. The utility model wraps the polishing wheel and a part of the steel pipe section by setting a deepened water tank. The water outlet pipe supplies water or cutting fluid to the polishing wheel and the dripping water wiping block for wiping the welded joint of the steel pipe. By pre-supplying water or cutting fluid once through the dripping water wiping block, the effect of fully wetting the welded joint of the steel pipe can be achieved, and the polishing effect can be optimized.
[0015] 2. By setting a deepened water tank and a cover plate, the utility model directly avoids water or polishing fluid from splashing around and wetting the ground and corroding the equipment, and at the same time avoids dust from entering the water or cutting fluid.
[0016] 3. By setting the first water wiping block and the second water wiping block, the residual water and cutting fluid on the surface of the steel pipe can be fully wiped off, keeping the steel pipe and the surrounding ground dry, realizing the separation of dry and wet, and thus solving the problems in the prior art that the water or cutting fluid recovery effect of the welding joint station for grinding stainless steel pipe production lines is not good, resulting in dust inclusion, wetting the surrounding ground and corroding the equipment.
[0017] 4. In the utility model, there is a certain gap between the first water wiping block and the second water wiping block. After the first water wiping block wipes, it is naturally air-dried after a certain distance, and then the second water wiping block wipes, and the effect of removing water and cutting fluid on the surface of the steel pipe is relatively good.

Specific embodiments
[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0023] As Figures 1-3 shown, the present utility model provides a technical solution: a wet and dry separation device for polishing the welded joint of a stainless steel pipe, including a deepened water tank 4 with an open top arranged outside the polishing wheel 1, supporting wheel 2 and steel pipe 3. If the polishing wheel 1 and supporting wheel 2 are not convenient to disassemble, the deepened water tank 4 can be made by welding with steel plates. If the polishing wheel 1 and supporting wheel 2 are convenient to disassemble, the axles of the polishing wheel 1 and supporting wheel 2 are passed through the deepened water tank 4, the polishing wheel 1 and supporting wheel 2 are installed in the deepened water tank 4, and the deepened water tank 4 is fixed at the corresponding position on the production line.
[0024] The steel pipe 3 is located in the middle of the deepened water tank 4 to ensure that the deepened water tank 4 has sufficient depth to reduce the upward splash of polishing liquid or water. The distance between the polishing wheel 1 and the inner wall of the corresponding upstream side of the deepened water tank 4 is less than the distance between the polishing wheel 1 and the inner wall of the corresponding downstream side of the deepened water tank 4. The steel pipe 3 is conveyed to the left to ensure that the polished steel pipe 3 has a certain water draining distance in the deepened water tank 4.
[0025] Relief holes corresponding to the rotating shafts of the polishing wheel 1 and supporting wheel 2 are arranged on the front and back of the deepened water tank 4, through holes corresponding to the steel pipe 3 are arranged on both sides of the deepened water tank 4, and a water dripping wiping block 5 in contact with the top welded joint of the steel pipe 3 is arranged at a position upstream of the polishing wheel 1 in the deepened water tank 4. The water dripping wiping block 5 can be made of sponge block, felt block or cotton pad to absorb water or cutting fluid and wipe it on the welded joint of the steel pipe 3 to facilitate polishing.
[0026] The water-dripping wiping block 5 is installed in the deepened water tank 4 through the fixed clamp 10. The front and back inner walls of the deepened water tank 4 are provided with clamping grooves 401 for clamping the fixed clamp 10. An outlet pipe 7 connected to the water inlet pipe 6 is arranged between the water-dripping wiping block 5 and the polishing wheel 1. The outlet of the outlet pipe 7 extends above the polishing wheel 1 and the water-dripping wiping block 5 respectively.
[0027] A cover plate 8 is arranged above the deepened water tank 4. A relief groove 801 is arranged at the position of the cover plate 8 corresponding to the water inlet pipe 6. There are two cover plates 8 which are respectively located on both sides of the water inlet pipe 6. The side of the cover plate 8 away from the water inlet pipe 6 is movably hinged to the deepened water tank 4, and a turning handle 9 is arranged on the cover plate 8. The cover plate 8 is used for dust prevention and preventing the polished water and cutting fluid from splashing outwards.
[0028] An installation groove one 11 is arranged on the inner wall of the downstream side of the deepened water tank 4. A water wiping block one 12 sleeved on the surface of the steel pipe 3 is installed in the installation groove one 11. A through hole is also arranged at the position of the installation groove one 11 corresponding to the steel pipe 3. A water leakage hole one 1101 is arranged at the bottom of the installation groove one 11. The water wiping block one 12 can be made of a sponge block, a felt block or a cotton pad, and is used for wiping or absorbing the water or cutting fluid on the surface of the steel pipe 3. After being saturated with absorption, the water or cutting fluid flows back into the deepened water tank 4 through the water leakage hole one 1101.
[0029] An installation groove two 13 is arranged outside the downstream side of the deepened water tank 4. A water wiping block two 14 sleeved on the surface of the steel pipe 3 is installed in the installation groove two 13. Through holes are also arranged at the positions of both sides of the installation groove two 13 corresponding to the steel pipe 3. A water leakage hole two 1301 and a connecting pipe 15 communicated with the deepened water tank 4 are arranged at the bottom of the installation groove two 13. The water wiping block two 14 can be made of a sponge block, a felt block or a cotton pad, and is used for wiping or absorbing the water or cutting fluid on the surface of the steel pipe 3. After being saturated with absorption, the water or cutting fluid flows back into the deepened water tank 4 through the water leakage hole two 1301 and the connecting pipe 15.
[0030] The installation groove two 13 is installed on the side surface of the deepened water tank 4 through a connecting frame 16, and the distance between the installation groove two 13 and the deepened water tank 4 is not less than 20 cm. After being wiped by the water wiping block one 12, most of the water or cutting fluid on the surface of the steel pipe 3 is removed. During the movement of the steel pipe 3, when the steel pipe 3 is conveyed for a certain distance between the installation groove one 11 and the installation groove two 13, the water or cutting fluid on the surface can naturally evaporate, and then the secondary wiping by the water wiping block two 14 can remove most of the water or cutting fluid on the surface of the steel pipe 3, preventing the surrounding ground and equipment parts from being wetted.
[0031] Working principle: The welded joint of the steel pipe 3 is transported from right to left with the opening facing upwards. The water inlet pipe 6 and the water outlet pipe 7 transport water or cutting fluid to the polishing wheel 1 and the water-dripping wiping block 5. After the water-dripping wiping block 5 absorbs the water or cutting fluid, it automatically wipes and coats the water or cutting fluid onto the welded joint of the steel pipe 3 when the steel pipe 3 passes by. The polishing wheel 1 rotates at high speed driven by the driving mechanism to complete the polishing of the welded joint. The steel pipe 3 continues to be transported to the left and passes through the first water-wiping block 12 and the second water-wiping block 14 in sequence. The first water-wiping block 12 wipes off or absorbs the water or cutting fluid on the surface of the steel pipe 3. After being saturated with absorption, the water or cutting fluid flows back into the deepening water tank 4 through the first water leakage hole 1101. When the steel pipe 3 is transported for a certain distance between the first installation groove 11 and the second installation groove 13, the water or cutting fluid on the surface can naturally evaporate, and then the second water-wiping block 14 performs secondary wiping. After the second water-wiping block 14 is saturated with absorption, the water or cutting fluid flows back into the deepening water tank 4 through the second water leakage hole 1301 and the connecting pipe 15, which can remove most of the water or cutting fluid on the surface of the steel pipe 3. The deepening water tank 4 and the cover plate 8 prevent dust from entering and prevent the water or cutting fluid from splashing outwards, preventing the surrounding ground and equipment from being wetted, and realizing the separation of dry and wet.
