Description

Technical Field

[0001] The present invention relates to the technical field of stainless steel pipe wall oil cleaning, and specifically to an automatic oil cleaning mechanism applicable to the inner wall of stainless steel pipes. Background Technique

[0002] Stainless steel pipes are widely used. The oil removal process for the inner wall of stainless steel pipes can ensure product hygiene and safety while improving process performance. Therefore, the oil removal process for the inner wall of stainless steel pipes is a key step to further improve product quality.

[0003] However, there are still certain defects in the existing oil removal process for stainless steel pipes with specific diameters and widths. Since the processed steel pipes need to be actively delivered to the oil removal core parts, an oil removal component adapted to the inner diameter of the steel pipes is set to achieve the purpose of cleaning the pipe wall. However, after the steel pipes are processed, scale will appear inside due to the attachment of impurity particles and the enhancement of the adhesion of oil to impurities. In severe cases, double scratches will be caused to the inner wall of the pipe and the outer wall of the oil cleaning component. At the same time, the oil scale will also cause a certain deformation of the pipe body under the extrusion of the oil cleaning component with a specified size.

Detailed implementation manners

[0021] To make the objectives, technical solutions, and advantages of the present invention clearer and more explicit, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0022] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention.

[0023] The following describes a kind of automatic oil cleaning mechanism applicable to the inner pipe wall of a stainless steel pipe provided by some embodiments of the present invention in conjunction with the accompanying drawings.

[0024] Embodiment 1

[0025] Combined Figures 1 - 12 As shown, a kind of automatic oil cleaning mechanism applicable to the inner pipe wall of a stainless steel pipe provided by the present invention includes a steel pipe delivery mechanism 100, a stainless steel pipe 200 arranged inside the steel pipe delivery mechanism 100, a pipe wall sewage discharge mechanism 300 arranged on the steel pipe delivery mechanism 100, an automatic oil removal energy supply mechanism 400 arranged on the pipe wall sewage discharge mechanism 300, a pipe wall scale scraping mechanism 500 arranged outside the automatic oil removal energy supply mechanism 400, and an oil removal core head 600 arranged on the automatic oil removal energy supply mechanism 400. The automatic oil removal energy supply mechanism 400 is used to cooperate with the stainless steel pipe 200 to move horizontally at a uniform speed to provide kinetic energy for the oil discharge and impurity removal of the automatic oil removal energy supply mechanism 400 and the pipe wall scale scraping mechanism 500. The pipe wall scale scraping mechanism 500 is used to actively scrape the scale accumulated on the inner wall of the stainless steel pipe 200 by means of kinetic energy. The pipe wall sewage discharge mechanism 300 is used to actively discharge the scraped oil scale outwards, and at the same time absorb and discharge the remaining oil liquid on the inner wall of the stainless steel pipe 200.

[0026] The automatic oil removal energy supply mechanism 400 includes a protective core cover 410, a stability-increasing shaft sleeve 420 installed inside the protective core cover 410, an off-position transmission component 430 arranged inside the stability-increasing shaft sleeve 420, an auxiliary drive component 440 installed inside the protective core cover 410, a limit frame 450 arranged inside the protective core cover 410, a second spring 460 installed inside the limit frame 450, a clamping seat 470 movably installed inside the limit frame 450 and arranged at the top of the second spring 460, and a synchronous pulley 480 movably installed inside the clamping seat 470; An anti-slip washer is arranged outside the synchronous pulley 480, and a ring gear is arranged on one side of the synchronous pulley 480, and corrugated transverse grooves are opened outside the anti-slip washer; A terminal rod is arranged in the middle of the synchronous pulley 480, and both ends of the terminal rod are installed inside the two clamping seats 470 through bearings; The off-position transmission component 430 includes a female rod 431 movably installed inside the stability-increasing shaft sleeve 420, a T-shaped tooth shaft 432 arranged inside the female rod 431, a plug rod 433 installed at the bottom of the T-shaped tooth shaft 432, and a first spring 434 arranged outside the plug rod 433; The auxiliary drive assembly 440 includes a vertical rod 441 fixedly installed in the protective core cover 410, a second spring 442 arranged outside the vertical rod 441, a truss 443 movably installed outside the vertical rod 441 and bearing pressure on the top of the second spring 442, and a first gear 444 and a second gear 445 movably installed in the truss 443; The rod bodies of the first gear 444 and the second gear 445 are both provided with toothed discs 446, and the two toothed discs 446 are transmission-connected with chains 447; The pipe wall scraping mechanism 500 includes a rotation-assisting sleeve 510, and the outer wall of the rotation-assisting sleeve 510 is provided with evenly distributed grooves, and a scraper 520 is movably installed in the groove, and a built-in compression spring 530 is provided on the inner wall of the groove and the inner side of the scraper 520; The scraper 520 is composed of an L-shaped bracket with an inclined structure and a soft rubber scraper with a triangular structure; The rotation-assisting sleeve 510 is movably mounted on the outside of the protective core cover 410, and the end surface of the rotation-assisting sleeve 510 facing the T-shaped gear shaft 432 is provided with gear blocks distributed in a circumference; The oil removal core head 600 is a conical structure as a whole, and the threaded section at the inner end of the oil removal core head 600 is adapted to penetrate into the screw hole at the other end of the protective core cover 410; The surface of the oil removal core head 600 is provided with a lubricating layer.

[0027] When the stainless steel pipe 200 is placed horizontally inside the steel pipe delivery mechanism 100 and is actively and uniformly delivered, the stainless steel pipe 200 will pass through the oil removal core head 600, the automatic oil removal energy supply mechanism 400, the pipe wall scraping mechanism 500 and the pipe wall sewage discharge mechanism 300 in sequence. After the stainless steel pipe 200 passes through the automatic oil removal energy supply mechanism 400, the pipe wall of the stainless steel pipe 200 reversely presses and pushes the synchronous wheel 480, and the synchronous wheel 480 drives the first gear 444. With the linkage of the two toothed discs 446 and the chain 447, the second gear 445 will also be continuously driven. Finally, the second gear 445 will adapt to the transmission T-shaped gear shaft 432. At this time, the T-shaped gear shaft 432 will provide rotational kinetic energy to the pipe wall scraping mechanism 500, and at the same time, the plug rod 433 installed at the bottom of the T-shaped gear shaft 432 will provide kinetic energy for the components for removing oil and dirt in the pipe wall sewage discharge mechanism 300. As the rotation-assisting sheath 510 rotates along the inner wall of the stainless steel pipe 200 and the stainless steel pipe 200 moves laterally at a uniform speed, a number of scrapers 520 evenly distributed in a circle will quickly remove the accumulated oil stains under pressure, and the removed oil stains and foreign particles will penetrate into the pipe wall sewage discharge mechanism 300 under the reverse extrusion of the stainless steel pipe 200, and finally the oil stains and foreign particles that have entered the pipe wall sewage discharge mechanism 300 will be safely and quickly released due to the active pressure supply of the oil stain removal component.

[0028] Embodiment 2

[0029] Combined Figures 1 - 4 As shown, on the basis of Embodiment 1, the steel pipe delivery mechanism 100 includes a support frame 110, a support plate 120 installed at one end of the support frame 110, two sets of pipe delivery components 150 arranged in the support frame 110, a chassis 130 installed on the support frame 110, and a motor 140 installed in the chassis 130. The outer end of the transmission shaft in the motor 140 is installed with a first sub-gear; The pipe delivery component 150 includes two support plates 151, two bushings 152 installed in the support plates 151, bearings 153 arranged inside the bushings 152, a passive roller 154 installed in one of the bearings 153, and an active roller 155 arranged in the other bearing 153; Sheaths 156 are arranged on the exteriors of both the passive roller 154 and the active roller 155.

[0030] Preferably, the number of support plates 151 is four, and the number of bushings 152 is eight. The four support plates 151 are installed on the legs at both ends of 111 through nuts. The first sub-gear on the transmission shaft in the motor 140 meshes with the second sub-gear at one end of the active roller 155. At this time, the longitudinally arranged active roller 155 and passive roller 154 can provide stable delivery kinetic energy for the stainless steel pipe 200, thereby ensuring that the oil scale can be removed stably and safely by the oil cleaning component during the delivery of the stainless steel pipe 200.

[0031] Embodiment 3

[0032] Combined Figures 7 - 12 As shown, on the basis of Embodiment 1, the pipe wall sewage discharge mechanism 300 includes an oil removal core rod 310 installed on the threaded section of the protective core cover 410, a linkage shaft 320 movably installed inside the oil removal core rod 310, an impeller 330 installed at the inner end of the linkage shaft 320, an inner sleeve 340 installed inside the oil removal core rod 310, an annular pipe 350 installed on the pipe body of the oil removal core rod 310, and several diversion pipes 360 installed between the inner end of the annular pipe 350 and the oil removal core rod 310; An oil discharge pipe 370 is arranged at the outer end of the annular pipe 350. A number of evenly distributed clamps 380 are installed on the pipe wall of the oil removal core rod 310, and the oil discharge pipe 370 is adapted to penetrate through the several clamps 380; An oil filter pad 390 is arranged in the annular groove on the outer side of the oil removal core rod 310, and evenly distributed oil discharge notches are opened in the annular groove; Evenly distributed dredging holes are opened on the side of the oil removal core rod 310 close to the end of the auxiliary rotation sheath 510, and the oil removal core rod 310 is integrally in an elongated T-shaped structure.

[0033] Preferably, an anti-seepage gasket is provided between the end of the threaded section of the protective core cover 410 and the end surface of the screw hole of the oil removal core rod 310, and the rod body of the linkage shaft 320 can be installed in the screw hole of the oil removal core rod 310 through a bearing; When the pipe wall scraping mechanism 500 rotates as a whole and actively scrapes off the dirt accumulated on the inner wall of the stainless steel pipe 200, the dirt under the reverse extrusion force of the stainless steel pipe 200 will penetrate into the drainage holes on the side of the end of the oil removal core rod 310. As the impeller 330 rotates at a high speed, the oil and dirt will form a liquid pressure of sufficient strength in the inner cavity of the oil removal core rod 310, and cooperate with the outward air exhaust effect of the impeller 330, so that an oil transfer channel can be formed in the inner cavity of the stainless steel pipe 200.

[0034] A hollow hole is opened in the middle of the protective core cover 410 , and the end of the linkage shaft 320 away from the oil removal core rod 310 is adapted to penetrate into the hole in the middle of the protective core cover 410 , and the end of the linkage shaft 320 is driven by the mother rod 431 .

[0035] In order to improve the degree of wedging between the synchronous wheel 480 and the inner wall of the stainless steel tube 200 for lateral movement, after the gear lever synchronous wheel 480 is reversely squeezed by the inner wall of the stainless steel tube 200, the two second springs 460 and the two clamp seats 470 can assist the synchronous wheel 480 to further descend, and the truss 443 arranged outside the vertical rod 441 will further descend with the auxiliary support of the second spring 442. At the same time, the T-shaped gear shaft 432 can adapt to the teeth of the auxiliary rotation sleeve 510 for rotation without hindering the lateral movement of the stainless steel tube 200.

[0036] Working principle and usage process of the present invention: First, start the motor 140 in advance. Then, insert the stainless steel pipe 200 into a set of pipe feeding assemblies 150 away from the motor 140 until the inserted end of the stainless steel pipe 200 crosses the outside of the oil removal core head 600, and the inner end of the stainless steel pipe 200 is delivered towards the other set of pipe feeding assemblies 150. When the first sub-gear on the transmission shaft in the motor 140 drives the driving roller 155, the stainless steel pipe 200 passing through the driving roller 155 and the driven roller 154 can be uniformly stretched outwards. As the stainless steel pipe 200 passes through the synchronous pulley 480 and an extrusion force is applied to it, when the stainless steel pipe 200 stably moves horizontally, the synchronous pulley 480 will rotate under the pressure. At this time, the ring teeth on one side of the synchronous pulley 480 will drive the first gear 444. At this time, a tooth disc 446 on the rod body of the first gear 444 will cooperate with the chain 447 to drive another tooth disc 446. Finally, the second gear 445 will rotate at a constant speed. After the combined insertion rod 433 and T-shaped tooth shaft 432 are effectively supported by the first spring 434, the ring teeth at the bottom of the T-shaped tooth shaft 432 can be meshed and driven by the second gear 445. At the same time, the auxiliary rotation sheath 510 movably installed outside the protective core cover 410 can be effectively driven by the T-shaped tooth shaft 432. At this time, the overall pipe wall scaling mechanism 500 can continuously rotate while not hindering the stable horizontal movement of the stainless steel pipe 200, and finally, a plurality of scrapers 520 with a plurality of built-in compression springs 530 popping outwards will scrape the oil scale and impurity particles accumulated on the inner pipe wall of the stainless steel pipe 200.

[0037] After the oil scale and impurity particles are scraped off, with the reverse extrusion force of the horizontal movement of the stainless steel pipe 200, the oil scale and impurity particles will penetrate into the gap between the auxiliary rotation sheath 510 and the end face of the oil removal core rod 310. At the same time, the combined T-shaped tooth shaft 432 and the insertion rod 433 will drive the mother rod 431 to rotate. The ring teeth provided at the bottom of the mother rod 431 will drive the end of the linkage shaft 320 penetrating into the inner cavity of the protective core cover 410, and the impeller 330 provided at the other end of the linkage shaft 320 can rotate at a high speed in the inner cavity of the oil removal core rod 310. At this time, an outward exhaust air will be generated in the inner cavity of the oil removal core rod 310. Finally, under the high pressure of the exhaust air, the oil scale and impurity particles entering the inner cavity of the oil removal core rod 310 can be actively released outwards.

[0038] After the oil dirt and impurity particles on the inner wall of the stainless steel pipe 200 are scraped off and actively released outward by the oil removal mandrel 310, the remaining oil liquid on the inner wall of the stainless steel pipe 200 will be quickly absorbed by the pressured oil filter pad 390. The oil filter pad 390 that absorbs the remaining oil liquid can overflow the oil liquid into the cavities of the oil removal mandrel 310 and the inner sleeve 340 under the reverse extrusion of the stainless steel pipe 200. By connecting the outer end of the external suction pump to the oil discharge pipe 370, the oil liquid entering the cavities of the oil removal mandrel 310 and the inner sleeve 340 can be quickly sucked out. Thus, it can effectively ensure that after the stainless steel pipe 200 passes through this device, the oil dirt, impurity particles and remaining oil liquid on its inner wall can be efficiently removed.

[0039] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
