[0032] DETAILED DESCRIPTION
[0033] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.
[0034] The following describes the noun part of the polyurethane coating finished product transfer device 103 and the polyurethane coating production system 100 according to the present invention with reference to the accompanying drawings.
[0035] like Figures 1 to 3As shown, in a specific embodiment of the utility model, a polyurethane coating finished product transfer device 103 is provided, including a transfer pipeline, a filter 1 and a transfer pump 2, wherein the transfer pipeline is used to transfer the polyurethane coating finished product between the reaction kettle 101 and the finished product kettle 102; the filter 1 is arranged on the transfer pipeline and is used to filter the polyurethane coating finished product; the transfer pump 2 is arranged on the transfer pipeline and arranged downstream of the filter 1.
[0036] In the polyurethane coating production process, first, the polyurethane raw material needs to be placed in the reactor 101 for reaction to produce the polyurethane coating product, and then the polyurethane coating product needs to be transferred to the finished product reactor 102 through the transfer pump 2 and the transfer pipeline, so that the reactor 101 can quickly carry out the next round of production. Since particulate impurities are mixed in the polyurethane raw material, particulate impurities will also be mixed in the produced polyurethane coating product. In the present application, the polyurethane coating product is filtered by the filter 1 set on the transfer pipeline, so as to remove the particulate impurities in the polyurethane coating product, thereby avoiding the situation that the transfer pump 2 is easily stuck or damaged by particulate impurities when transporting the polyurethane product.
[0037] It should be noted that those skilled in the art can understand that the filter 1 needs to fully consider the filtration accuracy and rate according to the size of the particulate impurities in the finished polyurethane coating. Generally, a filter 1 with a filtration mesh number of 10 is selected, but the specific structure of the filter 1 is not the core invention of the present application and will not be elaborated.
[0038] In some embodiments, the material transfer pipeline includes a filter tube 4 and a plurality of feed branch pipes 3 respectively connected to a plurality of reactors 101 in a one-to-one correspondence, the downstream ends of the plurality of feed branch pipes 3 are intersected and connected with the upstream end of the filter tube 4, the downstream end of the filter tube 4 branches to form a plurality of discharge branch pipes 5, and the filter 1 is arranged on the filter tube 4. In the present application, the polyurethane coating finished products produced by the plurality of reactors 101 are filtered simultaneously by connecting the plurality of feed branch pipes 3 with the filter 1, thereby improving the filtering efficiency of the polyurethane coating finished product transfer device 103.
[0039] Preferably, after the polyurethane coating finished product is transferred, the residual polyurethane coating finished product in the transfer pump 2 is easy to form a crust, which may cause the pump blade of the transfer pump 2 to be stuck or the pump body to be damaged and sealed. In the present application, each discharge branch pipe 5 is provided with a transfer pump 2 that can selectively connect to the filter 1, that is, the polyurethane coating finished product in the same reactor 101 can be transferred to the finished product reactor 102 through multiple transfer pumps 2. When one of the transfer pumps 2 fails, it is only necessary to shut down the failed transfer pump 2, while the other transfer pumps 2 continue to perform the transfer operation, thereby ensuring the transfer efficiency of the polyurethane coating finished product, and then ensuring the production efficiency of the polyurethane coating.
[0040] Specifically, a first discharge switch valve 6 and a second discharge switch valve 7 are provided on the plurality of discharge branch pipes 5, and the first discharge switch valve 6 is arranged upstream of the transfer pump 2; a second discharge switch valve 7 is provided on the plurality of discharge branch pipes 5, and the second discharge switch valve 7 is arranged downstream of the transfer pump 2. In the present application, the first discharge switch valve 6 on the discharge branch pipe 5 is closed to prevent the polyurethane coating product that has passed through the filter tube 4 from entering the discharge branch pipe 5, and the second discharge switch valve 7 is closed to prevent the polyurethane coating product in other discharge branch pipes 5 from entering the discharge branch pipe 5, thereby preventing the transfer pump 2 on the discharge branch pipe 5 from participating in the transfer operation to clean or repair the transfer pump 2, thereby ensuring the transfer efficiency of the polyurethane coating product.
[0041] It should be noted that the working principle of the material transfer pump 2 is well known to those skilled in the art and does not belong to the core improvement part of the present application, so it will not be described here in detail.
[0042] In some embodiments, each feed branch pipe 3 is provided with a feed switch valve 8, and the feed switch valve 8 is used to control the opening and closing of the feed branch pipe 3 connected to each reactor 101, thereby realizing independent transportation of each reactor 101, thereby improving the transportation efficiency of the finished polyurethane coating.
[0043] Moreover, during the reaction of the polyurethane raw material, once an abnormality occurs in the reactor 101, it is necessary to immediately interrupt the reaction and rework or process the polyurethane raw materials and semi-finished products in the reactor 101. In the prior art, the polyurethane raw materials and semi-finished products in the reactor 101 can only be manually released using other containers and then recovered and reworked in batches. The whole process is cumbersome and the material loss is large. In the present application, a transfer pump 2 can be set on the feed branch pipe 3 corresponding to the reactor 101 without abnormality to extract the polyurethane raw materials and semi-finished products in the reactor 101 with abnormality to the reactor 101 without abnormality, thereby realizing emergency treatment of abnormal reactions, thereby reducing material loss and simplifying the operation process.
[0044] In some embodiments, the vertical height of the horizontal plane where the upstream end of the transfer pipe is located is greater than the vertical height of the horizontal plane where the downstream end of the transfer pipe is located, thereby facilitating the natural flow of the finished polyurethane coating from the reactor 101 to the transfer pump 2 to avoid severe shaking of the transfer pump 2 during the transfer process.
[0045] In some embodiments, the polyurethane coating finished product transfer device 103 further includes a heating structure 9, which is laid along the transfer pipeline and wound around the filter 1 and the transfer pump 2. In the present application, the polyurethane coating finished product is heat-insulated and transferred by the heating structure 9 to ensure the fluidity of the polyurethane coating finished product, thereby preventing the polyurethane coating finished product from forming a skin or agglomeration after cooling, thereby preventing the transfer pipeline, the filter 1 and the transfer pump 2 from being blocked to reduce the number of cleaning or replacement times; and the heating structure 9 is wound around the filter 1 and the transfer pump 2 to ensure the heating effect.
[0046] Specifically, the heating structure 9 is an electric heating structure, and the polyurethane coating finished product transfer device 103 also includes a temperature sensor and a controller, wherein the temperature sensor is used to measure the actual temperature of the polyurethane coating finished product; the controller is electrically connected to the electric heating structure and the temperature sensor, and is configured to control the switch of the electric heating structure and adjust the actual temperature. In the present application, the actual temperature is reflected in real time by the temperature sensor. When the actual temperature of the polyurethane coating finished product is low, resulting in low fluidity, the controller increases the heating temperature of the electric heating structure to increase the actual temperature; conversely, the heating temperature of the electric heating structure is reduced, thereby ensuring the fluidity of the polyurethane coating finished product and saving energy.
[0047] It should be noted that the working principle of the electric heating structure is well known to those skilled in the art and does not belong to the core improvement part of the present application, so it will not be repeated here. In addition, the electric heating structure is generally laid at an angle of 45° obliquely below the material transfer pipeline.
[0048] In some embodiments, the transfer pipe, the filter 1 and the transfer pump 2 are all wrapped with an insulation layer. In the present application, the polyurethane coating product in the transfer pipe, the filter 1 and the transfer pump 2 is insulated by providing an insulation layer, thereby ensuring the fluidity of the polyurethane coating product.
[0049] Preferably, the fluidity of the polyurethane coating product is ensured by providing the heating structure 9 and the insulation layer at the same time, thereby further saving energy. The thickness of the insulation layer is greater than 10 cm, which can have a better insulation effect.
[0050] In a specific embodiment of the utility model, a polyurethane coating production system 100 is also provided, comprising a reactor 101, a finished product reactor 102 and a polyurethane coating finished product transfer device 103, wherein the reactor 101 is used for the reaction of polyurethane raw materials to generate polyurethane coating finished products, the finished product reactor 102 is used for temporarily storing polyurethane coating finished products to facilitate the continued production of the reactor 101, and the polyurethane coating finished product transfer device 103 is arranged between the reactor 101 and the finished product reactor 102. Since the polyurethane coating production system 100 adopts all embodiments of the polyurethane coating finished product transfer device 103, the polyurethane coating production system 100 has all the beneficial effects brought by the polyurethane coating finished product transfer device 103.
