Description

Technical Field

[0001] This utility model relates to the technical field of composite material production equipment, and more specifically, to a feeding device for chemical-resistant and seawater-resistant composite material raw materials. Background Technology

[0002] Chemical and seawater corrosion resistant composite materials are widely used in marine engineering, chemical equipment and other fields. Their production process requires the transportation of various raw materials to mixing equipment. At present, the feeding device used to transport the raw materials of such composite materials mainly uses a transfer pump to transport liquid materials.

[0003] On the one hand, the conveying pipes, hoppers and other components of existing feeding devices are mostly made of ordinary metal or plastic. When they come into contact with highly corrosive raw materials (such as materials containing chloride ions, acids and alkalis) or are in a seawater environment, they are very prone to corrosion and damage. This not only affects the service life of the device, but may also cause raw material leakage due to component corrosion, polluting the production environment, and even affecting the purity of the raw materials and the performance of composite materials.

[0004] Meanwhile, raw materials are prone to agglomeration during transportation due to low temperatures. Especially in low-temperature environments, agglomerated raw materials can clog pipelines, reduce feeding efficiency, and affect the performance. Therefore, we propose a feeding device for chemically and seawater-resistant composite material raw materials. Utility Model Content

[0005] The purpose of this invention is to provide a feeding device for chemical-resistant and seawater-resistant composite material raw materials to solve the defects mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0011] Preferably, both the anti-corrosion suction pipe and the anti-corrosion discharge pipe are provided with an insulation sleeve, and the thickness of the anti-corrosion layer is between 0.8mm and 1.5mm.

[0012] Preferably, the conical hopper is funnel-shaped, and the plane containing the inner wall of the conical hopper is inclined downward at 45° to 60°.

[0013] Preferably, a top cover is fixedly installed on the top of the raw material tank, and a feed hole is provided on the top cover;

[0014] This setting facilitates the addition of raw materials.

[0015] Preferably, a stirring motor is fixedly installed on the top cover, and a vertically arranged stirring shaft is fixedly installed at the end of the output shaft of the stirring motor. Multiple stirring blades are fixedly installed on the stirring shaft, and the stirring blades are located inside the conical hopper.

[0016] This setting facilitates material mixing and promotes material discharge.

[0017] Preferably, a vertically arranged side plate is fixedly installed on the top cover, a cover plate is hinged to the wall of the feed hole, and a cylinder is hinged between the cover plate and the side plate. The cylinder is used to drive the cover plate to complete the opening and closing operation.

[0018] This feature effectively seals the feed inlet, while also making the cover easy to open and close.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This utility model effectively improves the overall chemical resistance and seawater corrosion resistance of the device by setting anti-corrosion layers on the inner and outer surfaces of the raw material tank and the conical hopper, and by using suitable corrosion-resistant materials for the anti-corrosion suction pipe and the anti-corrosion discharge pipe. This avoids problems such as damage caused by component corrosion, raw material leakage and impaired purity, ensures the performance of composite materials, and extends the service life of the device.

[0021] 2. This utility model, by setting multiple temperature-controlled electric heaters on the anti-corrosion suction pipe, combined with the heat preservation effect of the heat preservation cover and heat preservation sleeve, prevents the raw materials from clumping due to excessively low temperature. At the same time, the funnel-shaped design of the conical bucket and the stirring blades driven by the stirring motor promote the flow and discharge of the raw materials, avoid pipe blockage, and improve the feeding efficiency.

[0022] 3. This utility model facilitates the addition of raw materials and effectively seals the feed hole on the top cover and prevents impurities from entering through the cylinder-controlled cover plate; the heat preservation cover can be detached and installed through the side fixing ring, which is convenient for installation, removal and maintenance.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0031] Please see Figures 1-3This utility model provides a technical solution: a feeding device for chemically and seawater-resistant composite material raw materials, including a raw material tank 1, a conical hopper 10 fixedly installed at the bottom of the raw material tank 1, and anti-corrosion layers 19 provided on the inner and outer surfaces of the raw material tank 1 and the conical hopper 10; a vertical pipe 3 fixedly installed at the bottom of the conical hopper 10, a discharge valve 30 fixedly installed on the vertical pipe 3, an anti-corrosion suction pipe 20 fixedly installed at the bottom of the vertical pipe 3, a quantitative feeding pump 2 fixedly installed at the end of the anti-corrosion suction pipe 20, an anti-corrosion discharge pipe 21 fixedly installed at the outlet end of the quantitative feeding pump 2, and multiple temperature-controlled electric heaters 23 for heating are provided at corresponding positions on the anti-corrosion suction pipe 20. The anti-corrosion layers 19 inside and outside the raw material tank 1 and the conical hopper 10, together with the anti-corrosion suction pipe 20 and the anti-corrosion discharge pipe 21, enhance the chemical and seawater corrosion resistance of the device, the quantitative feeding pump 2 ensures accurate feeding, and the temperature-controlled electric heaters 23 prevent raw material agglomeration, thus improving the practicality of the device.

[0032] In this embodiment, the anti-corrosion layer 19 can be made of polytetrafluoroethylene (PTFE) material, and the thickness of the anti-corrosion layer 19 is between 0.8mm and 1.5mm. It can effectively resist chemical corrosion and seawater corrosion, and extend the service life of the raw material tank 1. The vertical pipe 3, the anti-corrosion suction pipe 20, and the anti-corrosion discharge pipe 21 can all be made of ultra-high molecular weight polyethylene (UHMWPE), which has excellent corrosion resistance and wear resistance, and a low coefficient of friction, which can reduce the adhesion and blockage of raw materials. The discharge valve 30 and the quantitative feeding pump 2 can be made of corrosion-resistant valves and pump bodies, respectively, so that the whole has a good anti-corrosion effect.

[0033] like Figure 3 As shown, two symmetrical heat insulation covers 22 are provided at corresponding positions on the anti-corrosion suction pipe 20. The temperature-controlled electric heater 23 is fixedly installed on the inner wall of the heat insulation cover 22, so that the heat of the temperature-controlled electric heater 23 can be more concentrated on the anti-corrosion suction pipe 20, while reducing heat loss, enhancing the heating and heat preservation effect, and better preventing the raw materials from clumping.

[0034] like Figure 3 As shown, a side fixing ring 24 is fixedly installed at the end of the heat insulation cover 22. The two corresponding side fixing rings 24 are detachably connected by fastening screws, making the installation and removal of the heat insulation cover 22 more convenient and facilitating the maintenance and repair of the temperature control electric heater 23 and the anti-corrosion suction pipe 20.

[0035] like Figure 3 As shown, both the anti-corrosion suction pipe 20 and the anti-corrosion discharge pipe 21 are equipped with heat insulation sleeves 25. The heat insulation sleeves 25 further reduce heat loss during the conveying process and maintain the temperature stability during the conveying of raw materials.

[0036] like Figure 1As shown, the conical hopper 10 is funnel-shaped, and the plane of the inner wall of the conical hopper 10 is inclined downward at 45°~60°. The guiding effect of the inclined angle allows the raw material to flow more smoothly from the raw material tank 1 into the vertical pipe 3, reducing the residue of raw material in the conical hopper 10.

[0037] like Figure 1 As shown, a top cover 11 is fixedly installed on the top of the raw material tank 1. The top cover 11 is provided with a feed hole 12, which provides a convenient channel for adding raw materials, allowing operators to easily add raw materials into the raw material tank 1 and improving the efficiency of adding raw materials.

[0038] like Figure 1 As shown, a stirring motor 16 is fixedly installed on the top cover 11. A stirring shaft 17, which is arranged vertically, is fixedly installed at the end of the output shaft of the stirring motor 16. Multiple stirring blades 18 are fixedly installed on the stirring shaft 17. The stirring blades 18 are located inside the conical hopper 10. The stirring motor 16 drives the stirring blades 18 to rotate, which can stir and mix the raw materials in the conical hopper 10, and at the same time promote the raw materials to fall downwards, avoiding the accumulation and blockage of raw materials.

[0039] like Figure 1 As shown, a vertically arranged side plate 14 is fixedly installed on the top cover 11. A cover plate 13 is hinged to the wall of the feed hole 12. A cylinder 15 is hinged between the cover plate 13 and the side plate 14. The cylinder 15 is used to drive the cover plate 13 to complete the opening and closing operation. The cylinder 15 can drive the cover plate 13 to complete the opening and closing operation, which can effectively block the feed hole 12 to prevent impurities from entering the raw material tank 1, and can also conveniently control the opening and closing of the cover plate 13, making the operation flexible.

[0040] Finally, it should be noted that the quantitative feeding pump 2, temperature-controlled electric heater 23, stirring motor 16, cylinder 15, corresponding control system, and external power supply involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and adapted controllers and power supplies, are connected by wires. The specific connection method should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0041] When using the chemical-resistant and seawater-resistant composite material raw material feeding device of this utility model, the starting cylinder 15 drives the cover plate 13 to open the feed hole 12, and the raw material is added into the raw material tank 1 through the feed hole 12. The polytetrafluoroethylene anti-corrosion layer 19 inside and outside the raw material tank 1 and the conical hopper 10 plays an anti-corrosion role. The starting cylinder 15 closes the cover plate 13, and starts the stirring motor 16 on the top cover 11, which drives the stirring shaft 17 and stirring blades 18 to rotate inside the conical hopper 10, stirring the raw material and promoting its flow into the vertical pipe 3.

[0042] Open the discharge valve 30, and the raw material enters the corrosion-resistant suction pipe 20 made of ultra-high molecular weight polyethylene through the vertical pipe 3. Turn on the temperature-controlled electric heater 23, and work with the insulation sleeve 25 outside the corrosion-resistant suction pipe 20 and the corrosion-resistant discharge pipe 21 to prevent the raw material from clumping. Start the quantitative feeding pump 2, and the raw material is quantitatively transported to the target equipment through the corrosion-resistant discharge pipe 21.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
