Description

Technical Field

[0001] The utility model relates to the technical field, and particularly relates to a temperature control and regulation device for the forming of bamboo fiber composite corrugated pipes. Background Art

[0002] In the production process of bamboo fiber composite corrugated pipes, it is necessary to carry out hot melting treatment on raw materials, and after sufficient mixing, a liquid material is formed. Then, the liquid material is stably transported into a forming device, and after temperature control and forming, a pipe body is formed, and finally the forming and discharging of the corrugated pipe are realized.

[0003] However, since there is a certain proportion of bamboo fiber particles in the raw materials of bamboo fiber corrugated pipes, their physical properties determine that the melting point temperature is lower than that of traditional plastic raw materials. In the process of production using traditional processes, the composite materials often burn due to too high temperature, which in turn causes the materials in the forming device to change in nature. In the lightest case, the pipeline is blocked, and in the most serious case, the equipment is damaged, which has a certain degree of risk.

[0004] After testing and discussion by R & D personnel, it is found that the main problem of the existing temperature control and regulation device for corrugated pipes lies in the unreasonable structural design of the temperature control equipment. During the temperature control and regulation process, the temperature control efficiency is not high. At the same time, combined with the temperature overshoot that automatically occurs during the fluid material transportation process, the cooling requirement of the equipment is often increased. The structure of the existing temperature control equipment is relatively simple, and the cooling and regulation ability during the fluid transportation process is poor, and it cannot meet the current production requirements. Content of the Utility Model

[0005] The purpose of the utility model is to provide a temperature control and regulation device for the forming of bamboo fiber composite corrugated pipes to solve the technical problem of low efficiency in the temperature control process in the prior art and inability to meet the demand for rapid cooling. Among the many technical solutions provided by the utility model, the preferred technical solution is that through the heat exchange tube type cooling design with a surrounding design and combined with a protective plate, it can reduce the influence of the residual heat of the electric heating cover on the forming pipeline and the heat exchange tube when the electric heating cover is not working, significantly improve the cooling efficiency, and avoid the temperature overshoot during the movement of the fluid material inside the forming pipeline. For details, see the following description.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0012] The protection plate is arranged on the outer wall of the heat exchange tube for heat insulation;

[0013] The electric heating cover is arranged outside the protection plate for cooperating with the temperature rise.

[0014] Preferably, a temperature and pressure gauge for detecting the pressure and temperature states inside the formed pipe is arranged on the outer wall of the transition section.

[0018] Preferably, the thickness of the protection plate is 2 - 3 mm, and the manufacturing material of the protection plate is one of copper, steel or aluminum.

[0029] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope protected by the present utility model.

[0030] Refer to Figures 1-5 as shown, the present utility model provides a temperature control and adjustment device for the forming of bamboo fiber composite corrugated pipes, including:

[0031] A forming pipe 5 for conveying hot-melt materials, one end of the forming pipe 5 is connected with a hopper 4, and the hot-melt raw materials are put in from the hopper 4. After stirring and conveying, they enter the forming pipe 5 for preliminary melting treatment, and the melted materials will move inside the forming pipe 5;

[0032] A transition section 1 fixedly connected to the forming pipe 5 for cooperating with the installation of the forming pipe 5. The number of the forming pipes 5 and the transition sections 1 is multiple, and can be adjusted according to the physical characteristics of the processed pipes, so as to meet different temperature control requirements;

[0033] An installation groove 2 is opened on the outer wall of the forming pipe 5. The installation groove 2 is of a circumferential design and is opened on the outer wall of the forming pipe 5, which can cooperate with the installation of the heat exchange tube 3. The width of the installation groove 2 is equal to the width of the heat exchange tube 3 for convenient installation;

[0034] A heat exchange tube 3 is arranged in the installation groove 2. The structural dimensions of the heat exchange tube 3 correspond to those of the installation groove 2, and it can be positioned by closely adhering to the inner wall of the installation groove 2. The installation groove 2 is circumferentially opened on the outer wall of the forming pipe 5. With this structural design, the water supply structure can be simplified by only designing a single water supply end and a water outlet end, improving the efficiency of water flow circulation, and further improving the heat exchange speed. The heat exchange tube 3 is of a U-shaped tube structure and adheres to the inner wall of the installation groove 2, which can contact the installation groove 2 to achieve the purpose of heat conduction;

[0035] The protective plate 7 is arranged on the outer wall of the heat exchange tube 3 for heat insulation. The protective plate 7 is arranged on the outside of the heat exchange tube 3. The protective plate 7 is used to isolate the heat exchange tube 3 from the electric heating cover 6, so as to prevent the residual heat generated by the electric heating cover 6 in the non-working state from affecting the heat exchange tube 3, thereby improving the heat exchange efficiency.

[0036] The electric heating cover 6 is arranged outside the protective plate 7 and is used for heating. When the electric heating cover 6 is powered on, the temperature is increased to heat the forming pipe 5, so that the liquid material inside the forming pipe 5 is in a molten state.

[0037] During use, the material is put into the feeding equipment from the feeding hopper 4 for mixing, and is fully stirred by the mixing equipment, accompanied by heating and hot melting, so that the material entering the molding pipe 5 is in liquid state, and then the material will continue to move along the molding pipe 5 as the feeding mechanism is continuously advanced. During the movement, the temperature state needs to be controlled. At this time, the external heat exchange equipment will supply cooling water into the heat exchange pipe 3 for transportation, so as to achieve the purpose of zoned cooling. It should be noted that some pipes produced from bamboo fiber materials will generate high temperatures due to frictional heat during transportation. At this time, the electric heating hood 6 needs to stop working and use the heat exchange pipe 3 for heat exchange and cooling to finally achieve positioning.

[0038] In another embodiment, a temperature and pressure gauge 8 for detecting the pressure and temperature state inside the forming pipe 5 is provided on the outer wall of the transition section 1. The temperature and pressure gauge 8 is used to test the pressure and temperature indicators inside the forming pipe 5. During the transportation process, the temperature of the liquid material at different transition sections 1 is detected to facilitate the temperature adjustment, thereby meeting the process requirements of gradually cooling down during pipeline production.

[0039] In another embodiment, the protective plate 7 and the electric heating cover 6 both adopt a split structure, and the protective plate 7 and the electric heating cover 6 are installed in a symmetrical structure. They can be fastened to each other and fixed with bolts to ensure the sealing effect, reduce heat loss, and ensure that the formed pipe 5 is heated evenly.

[0040] In another embodiment, a positioning groove that cooperates with the formed pipe 5 is opened on the transition section 1. The positioning groove can facilitate the installation of the formed pipe 5 and the splicing process, and the length can be adjusted according to practical needs.

[0041] In another embodiment, the thickness of the protective plate 7 is -mm, and the manufacturing material of the protective plate 7 is one of copper, steel or aluminum. Due to the different materials of copper, steel and aluminum, their thermal conductivity efficiencies are also different. The thickness of the protective plate 7 combined with the manufacturing material can control the thermal conductivity efficiency, so that targeted adjustments can be made according to the production requirements of different materials.

[0042] The above are only the specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily conceive of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
