[0002] In the production field of plastic pipes, the extruder is a key equipment widely used, which can efficiently process plastic raw materials into continuous pipes. The pipe after extrusion usually needs to be cooled immediately to ensure the dimensional stability, physical properties and appearance quality of the pipe.

[0003] Traditionally, most production enterprises adopt a simple water tank cooling method, which is commonly known as gradually pushing the extruded pipe into the water tank, and the pipe enters the water tank from the inlet, is cooled by normal temperature water in the water tank, and is removed from the outlet. Although this cooling method has simple structure and low cost, it has serious defects in actual production process. As the production continues, the pipe carries a large amount of heat into the water tank, and exchanges heat with the normal temperature water, so that the water temperature in the water tank rises rapidly. The sharp rise of water temperature leads to sharp decline of cooling effect, which cannot meet the cooling demand of the pipe, and further causes the dimensional accuracy of the pipe to be difficult to guarantee, which may cause problems such as pipe diameter deviation and uneven pipe wall thickness, and seriously affects the product quality.

[0034] When an element is referred to as being "fixed" or "set" on another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or indirectly connected to the other element.

[0035] The terms "inner, outer" refer to the inner and outer of the contour of each component itself. The terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only used to facilitate the description of the present application and simplify the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0037] The pipe extrusion cooling device provided by the utility model will be described.

[0038] As shown in Figure 1 and Figure 3 , the utility model first embodiment provides a kind of pipe extrusion cooling device, including cooling tank mechanism 10, liquid storage mechanism 20, refrigerator 30 and pumping mechanism 40.Cooling tank mechanism 10 is used to cool pipe when passing;Liquid storage mechanism 20 is connected with the water outlet of cooling tank mechanism 10 by first pipe line 70;Refrigerator 30 inlet and liquid storage mechanism 20 are connected by second pipe line 72, outlet and liquid storage mechanism 20 are connected by third pipe line 73;Pumping mechanism 40 is arranged on the fourth pipe line 74 between liquid storage mechanism 20 and cooling tank mechanism 10, for pumping cold water to cooling tank mechanism 10.

[0039] Wherein, fourth pipe line 74 includes first main pipe 741, a plurality of first branch pipe 742 and second branch pipe 743 as shown in Figure 7 First main pipe 741 is horizontally arranged at one side of cooling tank mechanism 10, and the axis direction of first main pipe 741 is parallel with the length direction of cooling tank mechanism 10;A plurality of first branch pipe 742 are arranged at the first side of first main pipe 741, and one end of each first branch pipe 742 is communicated with first main pipe 741, and the other end of each first branch pipe 742 is communicated with corresponding spray head 104;Second branch pipe 743 is arranged at the second side of first main pipe 741, and the first end of second branch pipe 743 is communicated with first main pipe 741, and the second end of second branch pipe 743 is communicated with pumping mechanism 40.

[0040] When water is sprayed, the water flow from the pumping mechanism 40 first flows into the second branch pipe 743, which serves as an input channel for the cooling water and stably guides the cooling water into the first main pipe 741 connected thereto. Since the first main pipe 741 is horizontally arranged at one side of the cooling tank mechanism 10 and has an axis direction parallel to the length direction of the cooling tank mechanism 10, after the water flow enters the first main pipe 741, it flows smoothly along the axial direction of the first main pipe 741. Since the first main pipe 741 has a large pipe diameter, the water flow is uniformly distributed. Then, the first branch pipes 742, which are arranged at the first side of the first main pipe 741 and have one end connected to the first main pipe 741 and the other end extending into the cooling tank mechanism 10, play a role of distributing the water flow. Since the first branch pipes 742 are uniformly distributed along the axial direction of the first main pipe 741, the water flow in the first main pipe 741 is accurately distributed into the cooling tank mechanism 10. For the first main pipe 741, considering that the first main pipe 741 needs to bear a large flow of water and its working environment, a material with high strength, corrosion resistance and certain heat conduction performance is preferably selected. For example, a stainless steel material.

[0041] The pipe material extrusion cooling device provided in the embodiment can ensure a better refrigeration effect on the pipe material when the pipe material passes through the cooling tank mechanism 10 by additionally arranging the liquid storage mechanism 20 and the refrigeration machine 30 outside the cooling tank mechanism 10 and connected to the cooling tank mechanism 10. The high-temperature hot water flowing out of the cooling tank 101 first flows into the water storage tank and is then pumped into the refrigeration machine 30. The refrigeration machine 30 cools the hot water entering the refrigeration machine 30, and the cooled water is mixed into the water storage tank again. In this process, the water storage tank plays a buffering and adjusting function, so that the water at different temperatures is fully mixed. This can not only ensure that the water temperature is constant each time the water is pumped into the cooling tank and that the cooling tank 101 can always obtain cooling water at a suitable temperature, thereby stably cooling the pipe material, but also can ensure that there is sufficient water in the water storage tank at any time to meet the large demand for cooling water in the continuous pipe material extrusion process and completely eliminate the problem of insufficient water leading to insufficient and untimely cooling.

[0042] The first pipe 70, the second pipe 72, the third pipe 73 and the fourth pipe 74 connected to the mechanisms cooperates with the pumping mechanism 40 to form a high-efficiency water circulation system. The pumping mechanism 40 accurately pumps the cooled water in the liquid storage mechanism 20 to the cooling tank mechanism 10 in time to ensure smooth cooling operation. The reasonable layout of the pipes effectively reduces the energy loss in the water flow process and improves the energy efficiency ratio of the entire cooling device.

[0043] As Figure 2The utility model discloses a kind of cooling tank mechanisms 10, including cooling tank 101, guide wheel 103 and spray head 104.The upper end of cooling tank 101 is opened, and the lower end is installed on rack 102, and the two ends of cooling tank 101 are sequentially provided with pipe inlet and pipe outlet along the direction of pipe material travel;Multiple guide wheels 103 are rotatably arranged in cooling tank 101 below pipe inlet, and are evenly distributed along the length direction of cooling tank 101;Multiple spray heads 104 are arranged in cooling tank 101 above pipe inlet, each spray head 104 is inclinedly arranged towards the direction of pipe outlet, and each spray head 104 is communicated with liquid storage mechanism 20 by fourth pipeline 74 and pumping mechanism 40 thereon.Pumping mechanism 40 is water suction pump.Two liquid return grooves 75 are respectively arranged on cooling tank 101 below pipe inlet and pipe outlet, the top end of each liquid return groove 75 is opened, and the bottom of each liquid return groove 75 is communicated with the end of corresponding second main pipe 701 by fifth branch pipe 76.

[0044] When working, on the one hand, low-temperature water in liquid storage mechanism 20 is extracted and transported to spray head 104 by pumping mechanism 40, and spray head 104 injects cooling water into cooling tank 101, and since each spray head 104 is inclinedly arranged towards the direction of pipe outlet, the circulation speed of cooling water in cooling tank 101 is accelerated during the process of spray head 104 spraying cooling water;On the other hand, pipe material enters cooling tank 101 from pipe inlet at one end of cooling tank 101 under the action of traction mechanism, and pipe material starts to enter the cooling treatment link, and multiple guide wheels 103 evenly distributed in cooling tank 101 below pipe inlet and along the length direction of cooling tank 101 support and guide pipe material entering cooling tank 101, so that pipe material can smoothly move towards the direction of pipe outlet along the length direction of cooling tank 101, and deviation, jam and other situations of pipe material during movement are reduced, and efficient and continuous cooling operation is realized.

[0045] In addition, two liquid return grooves 75 are respectively arranged on cooling tank 101 below pipe inlet and pipe outlet, and when cooling water in cooling tank 101 flows out of cooling tank 101 under the influence of some factors, the cooling water can flow back to second main pipe 701 through fifth branch pipe 76 arranged at the bottom of liquid return groove 75 with the opening at the top, and finally flow back to liquid storage mechanism 20, so as to be recycled subsequently.Compared with prior art, the design that liquid return groove 75 is communicated with corresponding pipeline facilitates the collection of used cooling water, is conducive to the recycling of cooling water, saves cooling water resources, reduces production cost, and the traction mechanism is prior art, such as belt drive traction.

[0046] As Figures 3 to 5As shown, the utility model provides a kind of concrete implementation mode based on the first embodiment as follows: liquid storage mechanism 20 includes liquid storage tank 21 and filter assembly 50.Liquid storage tank 21 is arranged below cooling tank 101, and is connected with the water outlet end of cooling tank 101 by first pipeline 70, in liquid storage tank 21, buffer chamber 211 and filter chamber 212 are sequentially provided along its height direction, buffer chamber 211 is connected with filter chamber 212 by connecting pipe 22, the liquid inlet of the top of buffer chamber 211 is connected with the lower end of first pipeline 70, the first liquid outlet of the bottom of filter chamber 212 is connected with the first end of fourth pipeline 74, second liquid outlet is provided on filter chamber 212 above first liquid outlet, and second liquid outlet is connected with refrigerating machine 30 by second pipeline 72;Filter assembly 50 is arranged in filter chamber 212 below connecting pipe 22, and filter assembly 50 is used to filter high-temperature water that flows back to liquid storage tank 21 from first pipeline 70.

[0047] Cooling water after being used in the cooling process of pipe material in cooling tank 101, it flows from cooling tank 101 to liquid storage tank 21 by first pipeline 70.Because liquid storage tank 21 is arranged below cooling tank 101, under the action of gravity, cooling water flows into the top buffer chamber 211 of liquid storage tank 21 smoothly, the liquid inlet of the top of buffer chamber 211 is connected with the lower end of first pipeline 70, and high-temperature cooling water first enters buffer chamber 211, at this time, the flow rate of cooling water is preliminarily slowed down due to space change, to avoid that it directly impacts the bottom of liquid storage tank 21 to cause larger disturbance.

[0048] And high-temperature cooling water that enters buffer chamber 211 stays in the cavity of buffer chamber 211 for a short time, and its flow rate is further stabilized, and then flows to filter chamber 212 through connecting pipe 22.Connecting pipe 22 plays a role of flow guide, and introduces cooling water after buffering into filter chamber 212, to ensure that cooling water enters the next processing link in a more stable state.

[0049] When the cooling water enters the filtering cavity 212, the filtering assembly 50 located in the filtering cavity 212 below the connecting pipe 22 starts to work. The filtering assembly 50 filters the high-temperature water flowing back to the liquid tank 21 from the first pipeline 70, and removes impurities that may be mixed in the cooling water during the cooling process, such as precipitates in the cooling tank 101 and the like. The filtered cooling water becomes pure and meets the requirements for recycling. The high-temperature water filtered through the filter plate 51 is pumped into the refrigerator 30 under the action of the second pipeline 72, and the refrigerator 30 cools the high-temperature water. The second pipeline 72 is also provided with a water pump, and the cooling water cooled by the refrigerator 30 flows back to the liquid tank 21 through the third pipeline 73. In this process, the water of different temperatures accumulated at the bottom of the liquid tank is fully mixed, and then the purified and cooled cooling water is pumped and delivered to the spray head 104 in the cooling tank 101 through the water pump on the fourth pipeline 74, sprayed into the cooling tank 101 and cooled the pipe material, so that the recycling of the cooling water is realized.

[0050] Compared with the prior art, by setting the filtering assembly 50 to filter the backflow cooling water, impurities can be effectively removed, the deposition and adhesion of impurities in the cooling tank 101, the spray head 104 and the pumping mechanism 40 and other equipment components are reduced, the risk of wear and blockage of these components due to impurities is reduced, and the service life of the entire cooling equipment is prolonged, the equipment maintenance cost and downtime maintenance time are reduced. At the same time, the design of the slow-flow cavity 211 makes the flow rate of the cooling liquid backflow stable, reduces the influence of the flow rate impact on the internal structure of the liquid tank 21 and the subsequent filtering, pumping and other links, and ensures the stable and orderly operation of the entire cooling circulation system, providing reliable support for continuous production.

[0051] As shown in Figures 4 to 5 A specific implementation provided on the basis of the first embodiment of the utility model is as follows: the filtering assembly 50 comprises a filter plate 51, a brush plate 52 and a discharge cavity 54. The filter plate 51 is arranged in the filtering cavity 212, and the upper surface of the filter plate 51 is inclined downward along the length direction thereof from the middle to both ends. The brush plate 52 is located above the filter plate 51, the brush 53 arranged at the lower end of the brush plate 52 is matched with the upper surface of the filter plate 51, and the upper end of the brush plate 52 moves reciprocatingly along the length direction of the filter plate 51 under the driving of the reciprocating assembly 60. Two discharge cavities 54 are arranged on both sides of the liquid tank 21 below the filter plate 51, each discharge cavity 54 is connected with the filtering cavity 212 through the first opening arranged at the top end and the second opening arranged at the bottom, and a third opening is arranged on the side of the liquid tank 21 corresponding to the discharge cavity 54. A miscellaneous storage box 55 is slidably arranged in each third opening, and the miscellaneous storage box 55 is connected with the filtering cavity 212 through the water filtering hole arranged at the bottom thereof. A flow divider 56 is further arranged in the filtering cavity 212 between the connecting pipe 22 and the reciprocating assembly 60.

[0052] After high-temperature water containing impurities enters the filter chamber 212, it falls onto the filter plate 51. Since the upper surface of the filter plate 51 slopes downwards from the middle to both ends along its length, the high-temperature water flows to both sides along the inclined surface of the filter plate 51. During this process, the high-temperature water is filtered by the filter plate 51, and the impurities are retained on the filter plate 51. The filtered high-temperature water then passes through the filter plate 51 into the space below it. The reciprocating assembly 60 drives the upper end of the brush plate 52 to move, causing the bristles 53 at the lower end of the brush plate 52 to move back and forth along the length of the filter plate 51. During this movement, the bristles 53 sweep away the impurities remaining on the upper surface of the filter plate 51 to both sides. The impurities swept to both sides of the filter plate 51 are then pushed into the discharge chamber 54 through the first opening at the top of the corresponding discharge chamber 54 by the action of the bristles 53, and then fall into the corresponding impurity storage box 55. The filter holes at the bottom of the impurity collection box 55 allow residual liquid that enters with impurities to flow back into the filter chamber 212, further achieving impurity collection and liquid separation. Compared with existing technologies, the reciprocating assembly 60 drives the brush plate 52 to reciprocate, automatically cleaning residual impurities on the filter plate 51 without the need for frequent manual cleaning, reducing labor costs and ensuring the continuous and effective filtration performance of the filter plate 51, preventing excessive impurity accumulation from affecting filtration efficiency. Meanwhile, the discharge chamber 54 and the impurity collection box 55 work together to provide a dedicated collection area for the cleaned impurities. The sliding design of the impurity collection box 55 facilitates periodic removal and cleaning of the collected impurities, making operation simple and convenient, and improving the overall practicality and convenience of the filter assembly 50.

[0053] In one specific embodiment, such as Figures 5 to 6 As shown, the reciprocating assembly 60 includes a reciprocating screw 61, a connecting plate 63, a sleeve 64, a guide rod 67, and a spring 66. The reciprocating screw 61 is horizontally arranged and rotatably mounted in the filter chamber 212 under the drive of the first motor 62; the connecting plate 63 is horizontally arranged, with its middle part threadedly connected to and passing through the reciprocating screw 61, and its two ends abutting against the inner walls of the filter chamber 212 respectively; the lower end of the connecting plate 63 is provided with a sleeve 64; the upper end of the brush plate 52 is provided with a lifting rod 65, the upper end of the lifting rod 65 slidingly extending into the sleeve 64, and the sleeve 64 is fitted with a spring 66, the two ends of the spring 66 abutting against the connecting plate 63 and the brush plate 52 respectively; two guide rods 67 are vertically arranged on the brush plates 52 on both sides of the lifting rod 65, and each guide rod 67 is slidably connected to and passes through the connecting plate 63.

[0054] When it is necessary to clean the impurities on the filter plate 51, the first motor 62 is started to drive the reciprocating screw rod 61 to rotate. Since the middle part of the connecting plate 63 is threadedly connected with the reciprocating screw rod 61, according to the screw transmission principle, the rotating reciprocating screw rod 61 will make the connecting plate 63 move reciprocatingly along the axial direction of the reciprocating screw rod 61; when the connecting plate 63 moves, the sleeve 64 at the lower end of the connecting plate 63 also moves. Since the lifting rod 65 at the upper end of the brush plate 52 is slidably extended into the sleeve 64, when the sleeve 64 moves, the brush plate 52 and the brushes below the brush plate 52 will be driven to move through the lifting rod 65. In this way, the reciprocating movement of the brush plate 52 along the length direction of the filter plate 51 is realized. During the movement of the brush plate 52, the spring 66 plays a role of buffering and pressure adjustment. When the brush plate 52 encounters obstacles or uneven surfaces on the filter plate 51, the spring 66 will automatically compress or elongate according to the size of the pressure received, so that the brush plate 52 can adapt to the surface conditions of the filter plate 51 and always maintain good contact between the bristles 53 and the upper surface of the filter plate 51, ensuring the cleaning effect of the impurities. In order to ensure the smooth reciprocating movement of the connecting plate 63, a light axis parallel to the reciprocating screw rod 61 is arranged in the filter cavity 212, and the light axis is slidably connected with the connecting plate 63 and penetrates through the connecting plate 63.

[0055] Compared with the prior art, the spring 66 is arranged to enable the brush plate 52 to automatically adjust the position and pressure according to the surface conditions of the filter plate 51, so that the bristles 53 and the filter plate 51 always maintain appropriate contact force. This not only can effectively clean the impurities on the filter plate 51, but also can avoid the problems of damaging the filter plate 51 due to excessive pressure or incomplete cleaning due to insufficient pressure, thereby improving the stability and reliability of the entire filtration system. The structure of the reciprocating assembly 60 is relatively simple, mainly composed of the reciprocating screw rod 61, the connecting plate 63, the sleeve 64, the guide rod 67 and the spring 66 and other basic components. The structure and principle of these components are relatively simple, and they have certain convenience in installation, debugging and maintenance, thereby reducing the maintenance cost and failure rate of the equipment.

[0056] As shown in FIG. 1, Figure 3 The first pipeline 70 includes a second main pipe 701, a plurality of third branch pipes 702 and a fourth branch pipe 704. The second main pipe 701 is horizontally arranged below the cooling tank 101, and the axial direction of the second main pipe 701 is parallel to the length direction of the cooling tank 101; the plurality of third branch pipes 702 are vertically arranged above the second main pipe 701, respectively, and the upper end of each third branch pipe 702 is in communication with the liquid leakage port arranged at the bottom of the cooling tank 101, and the lower end of each third branch pipe 702 is in communication with the second main pipe 701; the fourth branch pipe 704 is vertically arranged below the second main pipe 701, and the upper end of the fourth branch pipe 704 is in communication with the second main pipe 701, and the lower end of the fourth branch pipe 704 is in communication with the upper end of the liquid storage tank 21.

[0057] During the whole operation of the cooling device, the high-temperature cooling water first flows into the multiple third branch pipes 702 corresponding to the leakage opening arranged at the bottom of the cooling tank 101. Since the third branch pipes 702 are vertically arranged above the second main pipe 701, under the action of gravity, the high-temperature cooling water flows downwards along the third branch pipes 702 and converges into the second main pipe 701 horizontally arranged below the cooling tank 101. At this time, the second main pipe 701 is arranged along the axis parallel to the length direction of the cooling tank 101, so that the waste liquid flowing in is evenly distributed along the axial direction of the main pipe, avoiding the situation that the high-temperature waste water accumulates in a local area. Then, the waste liquid converging in the second main pipe 701 flows downwards through the fourth branch pipe 704 vertically arranged below the second main pipe 701, and finally flows into the upper end of the liquid storage tank 21, completing the collection and transfer of the high-temperature cooling water.
