Description

Technical Field

[0001] This application belongs to the field of high-pressure polyethylene technology, specifically relating to a stirring system. Background Technology

[0002] In plants that produce high-pressure polyethylene, multiple mixing devices are often used to operate simultaneously to ensure high production output and continuous operation of the production line. These mixing devices are equipped with multiple pipelines for feeding materials into the mixing device or discharging materials from the mixing device.

[0003] Due to space constraints in some factory areas, the equipment occupies a limited area. After the mixing equipment is installed, some small-diameter pipes are intertwined, making the pipeline layout in the workshop complex and inconvenient for operators. Summary of the Invention

[0004] To address the technical problem of complex piping in current high-pressure polyethylene manufacturing plants, this application provides a stirring system.

[0005] In a first aspect of this application, a stirring system is provided, comprising:

[0006] A stirring mechanism includes a stirring tank and a plurality of first pipes disposed in the stirring tank;

[0007] The pipeline integration mechanism includes a support body and a plurality of pipeline groups disposed on the support body. Each pipeline group includes at least one second pipeline and at least one valve. Each first pipeline is connected to one of the pipeline groups. Opening and closing the valves of different pipeline groups can allow fluid medium to flow from the corresponding pipeline group into the mixing tank or allow fluid medium to flow from the mixing tank out of the corresponding pipeline group.

[0008] In some embodiments, each of the pipe assemblies is equipped with a pressure gauge.

[0009] In some embodiments, the support body includes a vertically arranged first support plate and a second support plate, with two second support plates arranged opposite each other on both sides of the first support plate and at an included angle between the first support plate and the second support plate, the pipe assembly being arranged on the first support plate, and the second support plate having through holes for the second pipes to pass through.

[0010] In some embodiments, the first support plate is provided with a plurality of support members, which are in contact with the bottom of the second pipe or the bottom of the valve.

[0011] In some embodiments, the support member is provided with a locking element to secure the second pipe or the valve to the support member.

[0012] In some embodiments, the first support plate and the second support plate are provided with a thermal insulation layer.

[0013] In some embodiments, the support body further includes a door panel capable of closing the cavity between the first support plate and the second support plate, so that the door panel can cover the plurality of pipe assemblies.

[0014] In some embodiments, a shielding member is also provided on the top of the support body, and the orthographic projection of the shielding member on the ground covers the projection of the pipe integration mechanism on the ground.

[0015] In some embodiments, the top of the shield has an inclined surface.

[0016] In some embodiments, the bottom end of the support body is provided with support feet so that the height difference between the valve and the ground is within 1-1.6 meters.

[0017] The mixing system provided according to one or more embodiments of this application connects different pipe groups to a first pipe, and enables valves on the pipe groups to control the opening and closing of the corresponding first pipes. It is understood that the pipe integration mechanism integrates valves capable of controlling the second pipe. During operation, operators do not need to search for pipelines and their corresponding valves around the mixing tank; they only need to locate the corresponding pipe group and valve on the support body to quickly control the flow rate or volume of the medium in the second pipe. This simplifies operation and significantly improves work efficiency; the fast response ensures stable operation of the mixing tank. Furthermore, with the valves located on the support body, portions of the multiple first pipes connected to the mixing tank can be arranged side-by-side on the ground or above the workshop, reducing the complexity of pipelines within the workshop, minimizing the possibility of collisions and scrapes, and improving workshop safety.

Detailed Implementation

[0021] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0022] Please see Figure 1 and Figure 2 According to a first aspect of this application, a stirring system is provided, including a stirring mechanism and a pipeline integration mechanism 10 for producing high-pressure polyethylene. The stirring mechanism includes a stirring tank and a plurality of first pipelines disposed in the stirring tank. The stirring tank feeds the high-pressure polyethylene basic production mechanism, and different first pipelines are used to transport media such as peroxide and isododecane.

[0023] The pipeline integration mechanism 10 includes a support body 100 and a plurality of pipeline groups 200 disposed on the support body 100. Each pipeline group 200 includes at least one second pipeline 210 and at least one valve. Each first pipeline is connected to a pipeline group 200. Opening and closing the valves of different pipeline groups 200 can allow the fluid medium to flow from the corresponding pipeline group 200 into the mixing tank or allow the fluid medium to flow from the mixing tank out of the corresponding pipeline group 200.

[0024] By connecting different pipe groups 200 to the first pipe, and enabling the valves on the pipe groups 200 to control the opening and closing of the corresponding first pipes, it can be understood that the pipe integration mechanism 10 integrates valves that can control the second pipe 210. During operation, operators do not need to search for pipelines and their corresponding valve bodies 220 around the mixing tank. They only need to locate the corresponding pipe group 200 and valve on the support body 100 to quickly control the flow rate or volume of the medium in the second pipe 210. The operation is simple and can greatly improve work efficiency; the fast response ensures the stable operation of the mixing tank. At the same time, with the valves set on the support body 100, parts of the multiple first pipes connected to the mixing tank can be arranged side by side on the ground or above the workshop, reducing the complexity of pipelines in the workshop, reducing the possibility of collisions and scrapes, and improving the safety performance of the workshop.

[0025] The pipeline group 200 can be equipped with multiple second pipelines 210 or multiple valves as needed. The multiple second pipelines 210 are connected in parallel and / or in series through multiple valve bodies 220, so that the pipeline group 200 can meet the needs of the operators. Therefore, this application does not limit the number of second pipelines 210 and the number of valves in the pipeline group 200. Of course, each pipeline group 200 is marked to facilitate the differentiation by the operators.

[0026] In some embodiments, flanges are provided at the connection between the first pipe and the second pipe 210 to facilitate connection and disassembly. Of course, the first pipe and the second pipe 210 can also be connected by flexible hoses or welded through rigid pipes.

[0027] In some embodiments, each pipe assembly 200 is equipped with a pressure gauge to facilitate operators in checking whether the medium within each pipe assembly 200 is flowing normally. Of course, each pipe assembly 200 may also be equipped with a flow meter and a thermometer to further facilitate observation and operation by operators. Therefore, the pipe integration mechanism 10 may be equipped with an instrument box 300 to house instruments such as pressure gauges, thermometers, and flow meters.

[0028] In some embodiments, the support body 100 includes a vertically arranged first support plate 110 and a second support plate 120. The two second support plates 120 are arranged opposite to each other on both sides of the first support plate 110 and the first support plate 110 and the second support plate 120 are arranged at an included angle. The pipe assembly 200 is disposed on the first support plate 110, and the second support plate 120 is provided with a through hole for the second pipe 210 to pass through.

[0029] The first support plate 110 and the second support plate 120, which are arranged at an angle, enhance the strength of the support body 100, ensuring stable support for the multiple pipe assemblies 200 and improving the safety of the mixing system. The first support plate 110 and the second support plate 120 are made of stainless steel to extend their service life.

[0030] In some embodiments, a plurality of support members 400 are provided on the first support plate 110, and the support members 400 are in contact with the bottom of the second pipe 210 or the bottom of the valve.

[0031] By setting up the support member 400, the weight of the second pipe 210 and the valve can be transferred to the first support plate 110 through the support member 400. This ensures that both the first support plate 110 and the second support plate 120 are under stress, reducing the possibility of deformation of the through hole of the second support plate 120 under the weight of the second pipe 210, improving the service life of the pipe integration mechanism 10, and enhancing the safety of the mixing system. The support member 400 can be a plate-shaped piece or a strong structural component such as angle steel, and is installed on the first support plate 110 by welding or screwing.

[0032] In some embodiments, the support 400 is provided with a locking element to secure the second pipe 210 or valve to the support 400.

[0033] The second pipe 210 and / or valve are secured to the support 400 by multiple locking devices. This prevents displacement of the second pipe 210 and valve during operator operation, improving the integrity of the pipe integration mechanism 10 and enhancing its stability. It also reduces the likelihood of disconnection between the first and second pipes 210, thus improving workshop safety. U-bolts and matching nuts can be used.

[0034] In some embodiments, the first support plate 110 and the second support plate 120 are provided with insulation layers. The insulation layers keep the medium in the second pipe 210 warm, thereby ensuring that the materials in the stirring mechanism can react smoothly.

[0035] In some embodiments, the support body 100 further includes a door panel that can close the cavity between the first support plate 110 and the second support plate 120. Specifically, one end of the door panel is hinged to one of the second support plates 120, and the other end of the door panel is detachably connected to another second support plate 120. Rotating the door panel allows it to cover multiple pipe assemblies 200. On the one hand, the support body 100 has a cavity that can protect the pipe assemblies 200 and valves; on the other hand, the closed cavity also has a certain heat insulation effect.

[0036] In some plant areas, the mixing tanks are located outdoors. Therefore, in some embodiments, a shielding element 500 is also provided on the top of the support body 100. The orthographic projection of the shielding element 500 on the ground covers the projection of the pipe integration mechanism 10 on the ground. It is understood that the shielding element 500 provided on the top of the support body 100 has a certain shielding effect. It can not only block sunlight and reduce the impact of direct sunlight on the temperature of the second pipe body, but also block rainwater, reducing the probability of corrosion of the pipe assembly 200 and valves, reducing the maintenance frequency of the pipe integration mechanism 10, and increasing the service life of the pipe integration mechanism 10.

[0037] In some embodiments, the top of the shield 500 has an inclined surface. By setting the inclined surface, rainwater and dust can fall off under the influence of gravity, reducing the frequency of cleaning the improved pipe integration mechanism 10.

[0038] In some embodiments, the bottom of the support body 100 is provided with a support foot 600 to keep the height difference between the valve and the ground within 1-1.6 meters, so as to facilitate the operation of the valve by the operator, reduce the possibility of squatting or standing on tiptoe, and facilitate the operator to accurately adjust the valve. Of course, the length and width of the first support plate 110 and the second support plate 120 can be customized according to the working environment. For example, the first support plate 110 is about 1.7 meters wide and 1.5 meters high, the second support plate 120 is 0.3 meters wide and 1.5 meters high, and the support foot 600 is 0.5 meters high. The support foot 600 can be installed on the ground by screwing it on for easy disassembly and maintenance.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
