DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0027] See also Figures 1 to 6 The present invention provides the following technical solutions: a circulating cooling device for PE pipe production, comprising a cooling device body, the cooling device body comprising a surface cooling frame 1, a driving mechanism 2, a front cooling mechanism 3 and a rear cooling mechanism 4, a support frame 9 is welded to the inner side of the surface cooling frame 1, a first coolant tank 6 is arranged at the bottom of the surface cooling frame 1, a base 7 is formed integrally at the bottom of the first coolant tank 6, the driving mechanism 2 is inserted into the inside of the base 7, a traction rope 17 is wound on the surface of the driving mechanism 2, the front cooling mechanism 3 and the rear cooling mechanism 4 are both connected to the end of the traction rope 17, a first sliding frame 18 is welded to the bottom of the front cooling mechanism 3, a front rotation drive assembly 24 is built on the top of the first sliding frame 18, a second sliding frame 31 is welded to the bottom of the rear cooling mechanism 4, and a rear rotation drive assembly 25 is built on the top of the second sliding frame 31. The circulating cooling device for PE pipe production is used to cool down the entire PE pipe after the shaping process is completed.

[0028] When the device is used, the PE pipe is directly lifted by hoisting, and the two ends are placed horizontally on the top of the surface cooling frame 1 and the rear cooling mechanism 4 respectively. At this time, one end of the PE pipe is pressed against the support frame 9, and the other end of the PE pipe is pressed against the top of the rear return groove 32, and is pressed against and blocked by the rear plate 33 (even if the rear plate 33 cannot be completely sealed with the end of the PE pipe, it does not affect the subsequent cooling process). At this time, the driving mechanism 2 is started, and the pushing effect of the rear cooling mechanism 4 on the PE pipe makes the PE pipe docked with the front cooling mechanism 3, and placed on the front rotating drive shaft 15 assembly and the front return groove 32. Above the flow trough 22, the end of the PE pipe is again against the front end plate 23. In this state, starting the second circulation pump 20 can inject the cooling solution inside the second coolant tank 19 into the interior of the PE pipe through the front end plate 23, continue to control the operation of the drive mechanism 2, and start the rotation drive assembly and the first circulation pump 13 at the same time, so that the PE pipe can translate and rotate at the same time, and the surface of the PE pipe passing in the rotational translation state can be sprayed and cooled at the surface cooling frame 1, and the inner wall of the PE pipe is cooled by means of the cooling solution injected into the PE pipe, and the coolant on the surface and inside can achieve a temporary retention effect in the corresponding area.

[0029] In this embodiment, the two sides of the surface cooling frame 1 are integrally formed with side plates 5, and the inner wall of the side plates 5 is provided with a plurality of spray holes 12, and the top of one of the side plates 5 is screwed with a first circulation pump 13, one end of the first circulation pump 13 is inserted into the interior of the first coolant tank 6 through a pipeline, and the other end of the first circulation pump 13 is partially connected to each spray hole 12 through a pipeline, and a liquid reservoir 10 is provided on the inner side of the support frame 9, and a connecting hole 11 is provided at the bottom of the liquid reservoir 10, and the interior of the liquid reservoir 10 is connected to the interior of the first coolant tank 6 at the bottom through the connecting hole 11. The cooling solution can be directly immersed in contact with the PE pipe, so that the cooling liquid can be in contact with the PE pipe for a longer time, and as the PE pipe rotates, the area directly cooled is more comprehensive, further improving the cooling efficiency.

[0030] Specifically, when the PE pipe is moved from the inside of the surface cooling frame 1 in a rotating and translational form, the first circulation pump 13 on the top of the side plate 5 extracts the cooling solution from the inside of the first coolant tank 6, and the spray hole 12 on the inner wall sprays the cooling solution directly onto the surface of the PE pipe, and then drips toward the bottom along the side of the PE pipe, and then enters the inside of the liquid storage tank 10 and is temporarily stored inside the liquid storage tank 10. The two ends of the liquid storage tank 10 are blocked by the ends of the support frame 9, and the ends are directly pressed against the bottom arc surface of the PE pipe, so that a large amount of cooling solution can be avoided from overflowing from the two ends, and the cooling solution entering the liquid storage tank 10 will eventually flow back to the inside of the first coolant tank 6 along the connecting hole 11 at the bottom for recycling.

[0031] In this embodiment, the driving mechanism 2 includes a first motor 14 and a driving shaft 15. Both ends of the base 7 are provided with threading holes 8. One end of the driving shaft 15 is inserted into the output end of the first motor 14. A clamping plate 16 is welded on the surface of the driving shaft 15. There are four traction ropes 17, and one end of each traction rope 17 is wound on the inner side of the clamping plate 16. The traction ropes 17 are passed outward from the corresponding threading holes 8. The end of the driving shaft 15 is embedded in the inner wall of the base 7 through a bearing. While the cooling mechanism at both ends is used to cool the PE pipe as a whole, the entire device can also be controlled to be flexible and retractable, thereby improving space utilization, and the coolant can also be recycled to reduce the waste of the coolant.

[0032] Specifically, after starting the first motor 14, the rotation of the driving shaft 15 drives the clamping plate 16 to rotate, and then the internal traction rope 17 is reeled in or out. At this time, the front-end cooling mechanism 3 or the rear-end cooling mechanism 4 can be pulled closer respectively, and the other is pushed away by the PE pipe body, so as to achieve the purpose of translational movement of the PE pipe as a whole, and maintain this process to achieve the purpose of cooling the PE pipe.

[0033] In this embodiment, the front-end cooling mechanism 3 includes a front-end reflux groove 22 and a front-end plate 23. The front-end reflux groove 22 is built on the top of the first sliding frame 18, and the bottom of the front-end reflux groove 22 is integrally formed with a second coolant tank 19. A second circulating pump 20 is placed on the side of the first sliding frame 18. A delivery pipe 21 is inserted at one end of the second circulating pump 20. The end of the delivery pipe 21 passes through the middle position of the front-end plate 23. A hole is opened in the center of the front-end plate 23. The second circulating pump 20 is connected to the inside of the second coolant tank 19 through a pipe, and the bottom of the front-end reflux groove 22 is connected to the inside of the second coolant tank 19 through the hole. The surface and inner wall of the PE pipe can be directly in contact with the coolant at the same time. The surface cooling frame 1 part is directly in contact with the surface of the PE pipe, and the cooling mechanisms at both ends can directly inject the coolant into the inside of the surface of the PE pipe, thereby greatly increasing the contact area between the PE pipe and the coolant and improving the cooling speed.

[0034] Specifically, after one end of the PE pipe is pressed against the front-end cooling mechanism 3, the cooling solution inside the second coolant tank 19 will be injected into the interior of the PE pipe along the delivery pipe 21 through the second circulation pump 20, and at this time, the two ends of the PE pipe are pressed against each other through the front-end plate 23 and the rear-end plate 33 respectively, so most of the coolant cannot be quickly discharged in a short time, and can be accumulated at the bottom position of the inner wall of the PE pipe, and then as the rotating drive assembly drives the PE pipe as a whole to rotate, the cooling solution accumulated inside can be directly contacted with any position area of ​​the inner wall of the PE pipe to achieve the purpose of cooling.

[0035] In this embodiment, the rear end cooling mechanism 4 includes a rear end plate 33 and a rear end reflow groove 32, the rear end reflow groove 32 is welded to the top of the second sliding frame 31, the rear end plate 33 is integrally formed at the end of the rear end reflow groove 32, a third coolant tank 34 is provided at the bottom of the rear end reflow groove 32, the bottom of the rear end reflow groove 32 is connected to the interior of the third coolant tank 34 through a hole, the front end rotation drive assembly 24 and the rear end rotation drive assembly 25 both include a second motor 30 and a transmission belt 26, the surfaces of the first sliding frame 18 and the second sliding frame 31 are welded with a vertical plate 29, the shell part of the second motor 30 is fixed to one side of the vertical plate 29 with bolts, the surface of the vertical plate 29 is inserted with a support shaft 28, the surface of the support shaft 28 is sleeved with a gear 27, the transmission belt 26 is sleeved on the side of the gear 27, and the output shaft surface of the second motor 30 is connected to the end of the support shaft 28 through a chain for transmission.

[0036] Specifically, even in the process of cooling the PE pipe, the cooling solution inside the PE pipe leaks from both ends and can still directly fall into the second coolant tank 19 and the third coolant tank 34 through the holes at the bottom of the front reflux groove 22 and the rear reflux groove 32, so as to facilitate subsequent recycling and avoid waste of coolant. The rotary drive component part drives the central shaft to rotate through the transmission chain at the end of the second motor 30, and the central shaft cooperates with the gear 27 to drive the entire transmission belt 26 to rotate, and the transmission belt 26 controls the entire PE pipe to rotate. The transmission structure at the end of the second motor 30 adopts chain transmission, which is an existing mature technology and does not belong to the protection scope of the present invention. Therefore, the specific structure and operation principle of this part will not be described here.

[0037] The basic principles and main features of the present invention and the advantages of the present invention are shown and described above. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.

[0038] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
