Description

Technical Field

[0001] The utility model belongs to the technical field of coating production equipment, and in particular relates to a coating conveying device. Background Art

[0002] The production process of paint needs to go through many processes, including mixing, grinding, and blending of raw materials. Among these processes, the transportation of paint is a crucial link. In order to ensure the quality and stability of the paint, the fluidity and uniformity of the paint need to be maintained during the transportation process. However, in the actual production process, due to changes in ambient temperature or unreasonable design of the transportation pipeline, the paint may have problems such as uneven temperature and reduced fluidity during transportation, which may affect the quality of the paint.

[0003] Traditional paint delivery devices mostly use simple pipeline delivery structures. During the paint production process, due to the long delivery distance or unstable temperature inside the pipeline, the paint temperature is prone to fluctuate, which in turn affects the fluidity of the paint. Especially in winter or low temperature environments, the fluidity of the paint decreases more significantly, which may lead to blockage of the delivery pipeline or poor paint delivery. In addition, the long-term stay of the paint in the pipeline may also cause precipitation, stratification and other problems, further affecting the subsequent process. Utility Model Content

[0034] In order to make the objectives and advantages of the present utility model more clear and understandable, the present utility model will be specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present utility model, and does not strictly limit the specific scope of protection claimed by the present utility model.

[0035] Refer to Figures 1-5, a paint delivery device, including an inner pipe 1, with a flow guiding member 2 sleeved outside the inner pipe 1. The flow guiding member 2 is used to divert the heat preservation liquid; the flow guiding member 2 includes blocking rings 21 located at both ends of the inner pipe 1, and a plurality of dividing strips 22 are arranged between the two blocking rings 21. The dividing strips 22 are evenly distributed around the central axis of the inner pipe 1; the dividing strips 22 are designed in a spiral shape, which can guide the constant temperature liquid into a plurality of spiral delivery channels between the inner pipe 1 and the outer pipe 4; such a design can not only improve the flow efficiency of the constant temperature liquid, but also effectively extend the flow path of the constant temperature liquid, ensuring that the paint maintains a stable temperature inside the inner pipe 1, thereby guaranteeing the fluidity and uniformity of the paint;

[0036] A heat preservation outer pipe 4 is sleeved outside the flow guiding member 2; the outer pipe 4 plays a role of heat preservation and protection in the whole device. Through the multi-spiral channel structure between it and the inner pipe 1, the paint delivery effect can be further enhanced;

[0037] One end of the blocking ring 21 is embedded with an annular pipe 3, and the annular pipe 3 is used for the diversion and transmission of the constant temperature liquid. Through a reasonable structural design, the uniform flow of the constant temperature liquid in each channel is ensured; connectors 5 are arranged at both ends of the outer pipe 4, and the connectors 5 can be reliably connected to other delivery devices, so that the whole device can be flexibly docked with the production line, improving the compatibility and application range of the equipment.

[0038] Refer to Figures 1-3 , the shape of the dividing strip 22 is set to be spiral, and the dividing strip 22 divides the internal space of the inner pipe 1 and the outer pipe 4 into a plurality of spiral delivery channels; the design of these spiral delivery channels enables the constant temperature liquid to maintain its temperature to the greatest extent when flowing through the space between the inner pipe 1 and the outer pipe 4, and at the same time ensures that the paint is not affected by temperature changes during the delivery process; the spiral channels can also effectively increase the residence time of the constant temperature liquid, thereby further ensuring the temperature stability of the paint inside the inner pipe 1; this not only improves the fluidity of the paint, but also prevents the paint from coagulating or stratifying during the delivery process.

[0039] Refer to Figures 3-4, a receiving cavity 211 is formed on the side surface of the blocking ring 21, and the conveying annular pipe 3 is embedded into the receiving cavity 211. The design of the receiving cavity 211 enables the annular pipe 3 to be stably embedded therein, preventing the leakage of the constant-temperature liquid during transportation. A through hole 212 is formed through the receiving cavity 211, and the through hole 212 corresponds to the spiral channel between the inner pipe 1 and the outer pipe 4. The setting of the through hole 212 can ensure that the constant-temperature liquid will not be blocked or have uneven flow when entering the spiral channel. A output pipe 31 corresponding to the through hole 212 is fixedly connected to the side surface of the annular pipe 3, and the output pipe 31 is inserted into the through hole 212. The output pipe 31 ensures the stable transportation of the constant-temperature liquid, enabling it to enter each spiral channel evenly, thus providing guarantee for the constant-temperature transportation of the coating.

[0040] Refer to Figures 3-5 , an input pipe 32 is fixedly connected to the top of the annular pipe 3. The input pipe 32 is used to introduce the constant-temperature liquid into the annular pipe 3, ensuring that the constant-temperature liquid can enter the coating transportation system in a timely manner. A first clamping groove 213 is formed on the top of the blocking ring 21, and the input pipe 32 is clamped into the first clamping groove 213. The design of the first clamping groove 213 ensures the stable and reliable connection between the input pipe 32 and the annular pipe 3, preventing the leakage or loose connection of the constant-temperature liquid during the flow process.

[0041] Refer to Figures 4-5 , a sealing ring 52 is fixedly connected to the side surface of the connecting piece 5. The sealing ring 52 is inserted into the outer pipe 4. The sealing ring 52 can effectively prevent the leakage of the constant-temperature liquid and the coating during transportation, ensuring the airtightness of the system. A second clamping groove 521 is formed on the top of the sealing ring 52, and the second clamping groove 521 corresponds to the first clamping groove 213. The design of the second clamping groove 521 cooperates with the first clamping groove 213, making the installation of the input pipe 32 more convenient and ensuring the stability of the device during operation.

[0042] Refer to Figure 5 , connecting holes 51 evenly distributed at equal intervals around the central axis of the connecting piece 5 are formed through the side surface of the connecting piece 5. The design of these connecting holes 51 enables the outer pipe 4 to be stably connected to the connecting piece 5, preventing the vibration or shaking of the coating during transportation, and at the same time providing stronger structural stability and operation safety for the entire transportation device.

[0043] The working principle of the present utility model is as follows:

[0044] When transporting the coating material, it is necessary to input the constant-temperature liquid into the annular pipe 3 through the input pipe 32, and transport it into the space between the inner pipe 1 and the outer pipe 4 through the output pipe 31. The shape of the partition strip 22 is set to be spiral, and the partition strip 22 divides the inner space of the inner pipe 1 and the outer pipe 4 into multiple spiral conveying channels. In this way, the constant-temperature liquid will flow in the multiple spiral conveying channels, and then the inner pipe 1 can be maintained at a constant temperature, and the constant temperature is more conducive to the flow of the coating material in the inner pipe 1; the spiral flow channel can extend the flow path of the constant-temperature liquid, and then improve the residence time of the constant-temperature liquid between the inner pipe 1 and the outer pipe 4.

[0045] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present invention.
