Description

Technical Field

[0001] This utility model relates to the field of polyethylene filler masterbatch production technology, specifically a high-speed mixer for polyethylene filler masterbatch with a circulating water cooling system. Background Technology

[0002] Polyethylene filler masterbatch is a functional plastic additive, mainly composed of polyethylene resin and inorganic fillers. It is processed into high-concentration masterbatch for use in the production of plastic products. Its core function is to reduce the cost of plastics while improving the physical properties of materials. In the production process of polyethylene filler masterbatch, the high-speed mixer is a key pretreatment equipment. It is mainly used to efficiently mix, preheat and initially disperse raw materials such as polyethylene resin, inorganic fillers, coupling agents and lubricants, so as to provide a uniform premix for subsequent melt extrusion granulation.

[0003] In existing technologies, when high-speed mixers pre-treat raw materials, the high-speed stirring paddles generate a large amount of heat due to friction and shearing during mixing, which may lead to local overheating of the materials, causing softening of polyethylene or decomposition of additives, affecting product quality. Currently, intermittent air cooling is mostly used for cooling, with external fans for forced heat dissipation. However, the cooling efficiency is low and is greatly affected by ambient temperature, making it difficult to meet the needs of continuous production. Therefore, a high-speed mixer for polyethylene filler masterbatch with a circulating water cooling system is proposed to solve the above-mentioned technical problem of low cooling efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a high-speed mixer for polyethylene filler masterbatch with a circulating water cooling system, which has the advantage of high cooling efficiency and solves the problems of low cooling efficiency and great influence from ambient temperature, making it difficult to meet the needs of continuous production.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-speed mixer for polyethylene filler masterbatch with a circulating water cooling system, comprising a mixer body, wherein a circulating water cooling component is provided on the mixer body;

[0006] The circulating water cooling assembly includes a water cooling jacket and a plate heat exchanger. The water cooling jacket has a circular cross-sectional shape and is located on the outside of the mixing body. The plate heat exchanger is located on the mixing body. The mixing body is equipped with a circulation component, which is used to circulate the cooling water in the water cooling jacket.

[0007] Furthermore, the circulation component includes a first circulation pipe disposed on the water-cooling jacket, a circulation module disposed on the first circulation pipe along the cooling water flow direction, a second circulation pipe being connected to the output end of the circulation module, and a third circulation pipe being connected to the water-cooling jacket.

[0008] Furthermore, a support plate is provided on the water-cooling jacket, and the circulation module is mounted on the support plate.

[0009] Furthermore, the end of the first circulation pipe furthest from the water-cooling jacket is connected to the input end of the circulation module, the end of the second circulation pipe furthest from the circulation module is connected to the liquid inlet end of the plate heat exchanger, and the end of the third circulation pipe furthest from the water-cooling jacket is connected to the liquid outlet end of the plate heat exchanger.

[0010] Furthermore, the water-cooling jacket is provided with a number of heat-conducting needles along the vertical direction. The heat-conducting needles are provided on the water-cooling jacket and their two ends pass through and extend into the water-cooling jacket and the interior of the mixing body, respectively.

[0011] Furthermore, the heat-conducting needle is made of any one of copper, aluminum alloy, tungsten alloy, or zinc alloy.

[0012] Furthermore, the inner wall of the water-cooling jacket is provided with a plurality of first flow-slowing rings, and the inner wall of the water-cooling jacket is provided with a plurality of second flow-slowing rings, with the plurality of first flow-slowing rings and second flow-slowing rings being distributed in an alternating manner.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] 1. This high-speed mixer for polyethylene filler masterbatch with a circulating water cooling system uses a water-cooled jacket and a plate heat exchanger to uniformly cool the heated mixer body by using the cooling water in the water-cooled jacket that surrounds the mixer body. At the same time, the plate heat exchanger recovers the heat from the cooling water, reducing energy waste and enabling rapid cooling of the mixer body to prevent overheating of materials. This effectively avoids the problems of low efficiency and delayed temperature control of traditional air cooling.

[0015] 2. This high-speed mixer for polyethylene filler masterbatch with a circulating water cooling system significantly improves heat transfer efficiency by setting heat-conducting needles that penetrate the water cooling jacket and the inner wall of the mixer. At the same time, with the staggered distribution of the first and second slow-flow rings, the water flow path of the cooling water in the water cooling jacket is optimized, the residence time of the cooling water is extended, the heat exchange efficiency is improved, and the needs of high-load continuous production are met.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-2 The high-speed mixer for polyethylene filler masterbatch with a circulating water cooling system in this embodiment includes a mixer body 100, on which a circulating water cooling component 200 is provided.

[0023] It should be noted that the mixing machine 100 is a common piece of equipment in the prior art, and the method of use and working principle of the mixing machine 100 are well known to those skilled in the art of polyethylene filler masterbatch production, and will not be described in detail in this application.

[0024] The circulating water cooling assembly 200 includes a water cooling jacket 21 and a plate heat exchanger 22. The cross-sectional shape of the water cooling jacket 21 is circular, and the water cooling jacket 21 is disposed on the outside of the mixer body 100. The plate heat exchanger 22 is disposed on the mixer body 100. A circulation component is disposed on the mixer body 100, and the circulation component is used to circulate the cooling water in the water cooling jacket 21.

[0025] It should be noted that the water-cooling jacket 21 adopts a ring-shaped design, which tightly wraps the outer wall of the mixer body 100 to form a uniform cooling cavity. The cooling water in the water-cooling jacket 21 exchanges heat with the mixer body 100 to achieve cooling.

[0026] Furthermore, the circulation component includes a first circulation pipe 201 disposed on the water-cooling jacket 21, a circulation module 202 disposed on the first circulation pipe 201 along the cooling water flow direction, a second circulation pipe 203 connected to the output end of the circulation module 202, and a third circulation pipe 204 connected to the water-cooling jacket 21.

[0027] A support plate is provided on the water-cooling jacket 21, and the circulation module 202 is mounted on the support plate. The support plate provides support for the circulation module 202.

[0028] The end of the first circulation pipe 201 away from the water-cooled jacket 21 is connected to the input end of the circulation module 202; the end of the second circulation pipe 203 away from the circulation module 202 is connected to the liquid inlet end of the plate heat exchanger 22; and the end of the third circulation pipe 204 away from the water-cooled jacket 21 is connected to the liquid outlet end of the plate heat exchanger 22.

[0029] It should be noted that the plate heat exchanger 22 is a common device in the prior art. The plate heat exchanger 22 adopts a multi-layer corrugated plate stacking design to form alternating hot flow channels and cold flow channels. The special structure of the corrugated plates generates strong turbulence to cool the high-temperature cooling water. The high-temperature cooling water enters the plate heat exchanger 22 from the second circulation pipe 203, and the cooled water returns to the water-cooled jacket 21 through the third circulation pipe 204.

[0030] Please see Figure 3-4 In this embodiment, a plurality of heat-conducting needles 211 are arranged on the water-cooling jacket 21 along the vertical direction. The heat-conducting needles 211 are arranged on the water-cooling jacket 21 and their two ends respectively penetrate and extend into the water-cooling jacket 21 and the interior of the mixing body 100.

[0031] The heat-conducting needle 211 is made of any one of copper, aluminum alloy, tungsten alloy, or zinc alloy. Copper, aluminum alloy, tungsten alloy, and zinc alloy have good thermal conductivity and can quickly conduct the heat generated by the material in the mixing body 100 to the water-cooling jacket 21, reducing the risk of local overheating and ensuring temperature uniformity.

[0032] The inner wall of the water-cooled jacket 21 is provided with a plurality of first flow-slowing rings 212 and a plurality of second flow-slowing rings 213, and the plurality of first flow-slowing rings 212 and second flow-slowing rings 213 are distributed in an alternating manner.

[0033] It is known that the staggered first slow-flow ring 212 and second slow-flow ring 213 optimize the flow path of the cooling water in the water-cooled jacket 21, extend the residence time of the cooling water, and improve the heat exchange efficiency.

[0034] It should be noted that the control unit controls the start and stop of the circulation module 202 and the flow rate of the cooling water, so that the cooling water flows at a constant speed in the circulating water cooling component 200, thereby achieving uniform cooling of the mixing body 100; the control unit and its working principle are well known to those skilled in the art, and will not be described in this embodiment.

[0035] The working principle of the above embodiments is as follows:

[0036] When using the mixer 100 to pretreat polyethylene filler masterbatch raw materials, a large amount of heat is generated due to friction and shearing, causing localized overheating of the material, leading to softening of polyethylene or decomposition of additives, affecting product quality. At this time, cooling water flows through the water-cooled jacket 21, absorbing the heat generated by the mixer 100 as it passes through the chamber of the water-cooled jacket 21. After heat exchange, the cooling water leaves the water-cooled jacket 21 through the first circulation pipe 201 and is transported by the circulation module 202 through the second circulation pipe 203 to the plate heat exchanger 22. High-temperature cooling water flows from the second circulation pipe 203... 3. The cooling water enters the plate heat exchanger 22 and is cooled by the plate heat exchanger 22. It then returns to the water-cooled jacket 21 through the third circulation pipe 204, thus achieving the purpose of water-cooled circulation. At the same time, several heat conduction needles 211 can quickly conduct the heat generated by the material in the mixer body 100 to the water-cooled jacket 21, reducing the risk of local overheating and ensuring temperature uniformity. The staggered first slow flow ring 212 and second slow flow ring 213 optimize the water flow path of the cooling water in the water-cooled jacket 21, extend the residence time of the cooling water, improve the heat exchange efficiency, and meet the needs of high-load continuous production.
