Description

Technical Field

[0001] This utility model relates to the field of film spraying pipeline technology, and in particular to a controlled-release coating film spraying pipeline structure. Background Technology

[0002] The production of controlled-release fertilizer coating is currently a major trend in the industry, but its production technology, production process, and related production line processing equipment vary greatly. Many factories have outdated technology, low automation, and are still similar to workshop-style production, resulting in high energy consumption, high consumption of coating material, high costs, and uneven processing quality.

[0003] The coating process for controlled-release fertilizers is typically completed inside a rotating drum. The coating material is conveyed through a metal feed pipe that runs through the drum and then atomized by nozzles at the end before being evenly sprayed onto the granule surface. To ensure that the coating material remains fluid during conveying, the pipe must be continuously heated and insulated to prevent it from solidifying and clogging the nozzles due to cooling.

[0004] Currently, the industry commonly uses the method of externally wrapping the heating cable: the flexible electric heating cable is wound around the outer wall of the pipe in a spiral or straight manner, and then covered with insulation cotton. Although this structure is simple, it is difficult to wrap the heating cable evenly on the outside of the pipe, which easily leads to uneven insulation and significant temperature gradients throughout the pipe, resulting in poor insulation performance. Secondly, although insulation cotton is covered on the outside of the pipe, there is still a problem of significant heat loss, and the overall insulation cost is high. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a controlled-release coating material spraying pipeline structure. The heating oil pipe is located inside the coating material pipe, and the heating oil in the heating oil pipe can evenly heat and insulate the surrounding coating material, resulting in good insulation effect and small temperature differences in the coating material throughout the coating material pipe. At the same time, the method of insulating the coating material from the inside of the coating material pipe results in less heat loss and effectively reduces insulation costs.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: A controlled-release coating material spraying pipeline structure includes a heating oil pipe, an outer sleeve of the heating oil pipe and a coating material pipe passing through the coating material pipe, and a sealed connection between both ends of the coating material pipe and the outer wall of the heating oil pipe. The ends of the heating oil pipe are provided with flanges or joints, which are connected to the heating oil delivery pipeline through the joints. The ends of adjacent heating oil pipes are spliced ​​together through flanges. The coating material pipe is used to communicate with the coating material delivery pipeline.

[0007] As a further implementation, flanges are provided at both ends of the heating oil pipe to form an intermediate connecting pipe.

[0008] As a further implementation, a joint is provided at one end of the heating oil pipe and a flange is provided at the other end to form an end connecting pipe. At least one set of intermediate connecting pipes is connected between the two sets of end connecting pipes through a flange to realize the assembly of connecting pipes.

[0009] As a further implementation, the length of the heating oil pipe is greater than the length of the film material pipe, and the film material pipe is located between the two ends of the heating oil pipe.

[0010] As a further implementation, a blocking plate is provided between the end of the film material tube and the outer wall of the heating oil tube to seal the connection.

[0011] As a further implementation, the blocking plate is disposed near the end of the heating oil pipe, and the blocking plate is an annular shape with a central opening. The outer diameter of the blocking plate is adapted to the outer diameter of the film material pipe, and the inner diameter of the blocking plate is adapted to the outer diameter of the heating oil pipe.

[0012] As a further implementation, a first wire seat is provided at the middle position of the membrane material tube, and the first wire seat is connected to the membrane material conveying tube.

[0013] As a further implementation, multiple sets of second wire seats are evenly distributed along the length of the film tube, and the second wire seats are connected to the nozzle. The film tube is connected to the nozzle through the second wire seats.

[0014] As a further implementation, the flange is annular and has fixing holes, allowing adjacent flanges to be connected via fasteners.

[0015] As a further implementation, the heating oil pipe and the film material pipe are arranged coaxially; The heating oil pipe is composed of multiple sets of parallel heating branch pipes of equal length. The ends of the multiple sets of heating branch pipes are connected together by a flow divider connector. One end of the flow divider connector is provided with an inlet pipe, and the other end is provided with multiple sets of outlet pipes. Each set of outlet pipes is connected to each set of heating branch pipes.

[0016] The beneficial effects of this utility model are as follows: 1. The heating oil pipe of this utility model can be coaxially arranged with the film material pipe. The heating oil pipe is located inside the film material pipe. The heating oil in the heating oil pipe can evenly heat and keep the surrounding film material warm, resulting in good heat preservation effect and small temperature difference of film material in different parts of the film material pipe. At the same time, the method of heat preservation of film material from the inside of the film material pipe has small heat loss and effectively reduces heat preservation cost.

[0017] 2. This utility model improves the heat exchange area between the heating pipe and the film material by setting the heating oil pipe into multiple sets of heating branch pipes, thereby improving the heat exchange efficiency. Attached Figure Description

[0022] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0023] Example 1 In a typical embodiment of this utility model, refer to Figure 1 As shown, a controlled-release coating material spraying pipeline structure includes a heating oil pipe 1, a coating material pipe 2 sleeved on the heating oil pipe 1, and the heating oil pipe 1 passing through the coating material pipe 2. The two ends of the coating material pipe 2 are sealed to the outer wall of the heating oil pipe 1. A flange 7 or a connector 8 is provided at the end of the heating oil pipe 1, and the heating oil delivery pipeline is connected through the connector 8. The ends of adjacent heating oil pipes 1 are spliced ​​through the flange 7. The coating material pipe 2 is used to communicate with the coating material delivery pipeline.

[0024] like Figure 1 As shown, both ends of the heating oil pipe can be equipped with flanges 7, or one end can be equipped with a joint and the other end with a flange. The spraying pipe structure with flanges at both ends is the intermediate connecting pipe 20; the spraying pipe structure with a joint at one end and a flange at the other end is the end connecting pipe 10.

[0025] At least one set of intermediate connecting pipes 20 is connected between two sets of end connecting pipes 10 via flanges to achieve pipe assembly. Each set of intermediate connecting pipes and each set of end connecting pipes are of equal length.

[0026] For example, the length of the spraying pipe is determined according to the length of the coating roller. If five sets of connecting pipes need to be spliced, two sets of end connecting pipes and three sets of intermediate connecting pipes are required. The three types of intermediate connecting pipes are spliced ​​sequentially through flanges. The end connecting pipes are spliced ​​to the flange sections of the intermediate connecting pipes through their flange ends. After the overall splicing, the two sets of end connecting pipes are located at the ends of the spliced ​​pipe.

[0027] Two sets of connectors 8 are used to connect the heating oil delivery pipeline. One set of connectors is connected to one end of the heating oil outlet pipeline, and the other set of connectors is connected to one end of the heating oil return pipeline.

[0028] Understandably, the other end of the heating oil outlet and return lines are connected to the heating oil tank. The heating oil tank contains heating oil and is equipped with heating elements and a temperature sensor. An oil pump is also located at the heating oil tank. The heating oil outlet line is connected to the heating oil tank via the oil pump, which provides power for the circulation of heating oil between the outlet line, the connected pipe, and the return line. An electrical control box can be installed outside the heating oil tank to adjust the heating oil temperature, thereby controlling the operation of the electric heating elements based on the temperature sensor's detection of the heating oil.

[0029] Under the action of the oil pump, the heating oil enters the heating oil outlet pipe, then enters the end connecting pipe and the middle connecting pipe, and finally enters the heating oil pipe. It heats and keeps the film material in the film material pipe located around the heating oil pipe. The flowing heating oil finally returns to the heating oil pipe through the heating oil return pipe.

[0030] In addition, the heating oil pipe 1 and the film material pipe 2 are coaxially arranged. The heating oil pipe 1 is located inside the film material pipe 2. The heating oil in the heating oil pipe can evenly heat and keep the surrounding film material warm, resulting in good heat preservation effect and small temperature difference of film material in different parts of the film material pipe. At the same time, the method of heat preservation of film material from the inside of the film material pipe has small heat loss and effectively reduces heat preservation cost.

[0031] like Figure 1 and Figure 2 As shown, the length of the heating oil pipe 1 is greater than the length of the film material pipe 2, and the film material pipe 2 is located between the two ends of the heating oil pipe. Furthermore, the end of the film material pipe 2 is positioned close to the end of the heating oil pipe 1, and a blocking plate 6 is installed between the end of the film material pipe and the outer wall of the heating oil pipe to achieve a seal, so that the film material will not overflow from the end of the film material pipe.

[0032] In this embodiment, the plug plate is positioned near the end of the heating oil pipe. The plug plate is an annular shape with a central opening. The outer diameter of the plug plate matches the outer diameter of the film material pipe, and the inner diameter of the plug plate matches the outer diameter of the heating oil pipe. The plug plate can be made of metal, and the plug plate is welded to the heating oil pipe and the film material pipe for sealing.

[0033] Because the blocking plate is positioned close to the end of the heating oil pipe, the lengths of the film material pipe and the heating oil pipe are similar, thus ensuring a greater degree of heating and heat preservation effect of the heating oil on the film material.

[0034] like Figure 1 and Figure 2 As shown, a first wire seat 3 is fixedly installed at the middle position of each membrane material tube, and the first wire seat 3 can be connected to the membrane material conveying tube. The membrane material enters the membrane material tube through the membrane material conveying tube and the first wire seat 3.

[0035] Multiple sets of second wire seats 4 are evenly distributed along the length of the membrane material tube, and the nozzle 5 is connected through the second wire seats 4. The membrane material tube is connected to the nozzle through the second wire seats. The first wire seat 3 and the second wire seat 4 have the same structure, which is existing technology. After passing through the second wire seats, the membrane material is sprayed out from the nozzle 5. The sprayed membrane material is a liquid at a set temperature. Under the heating and heat preservation effect of the heating oil, the membrane material in the membrane material tube will not cool down and solidify.

[0036] like Figure 3 and Figure 4 As shown, the flange is annular and located at the end of the heating oil pipe. The flange has multiple fixing holes 71. When different heating oil pipes 1 are connected, they are joined through adjacent flanges 7 and fasteners 9. It can be understood that the fastener 9 is a bolt assembly, and the fixing holes 71 are through holes.

[0037] In a preferred example, the heating oil pipe is composed of multiple sets of parallel heating branch pipes of equal length. The ends of the multiple sets of heating branch pipes are connected together by a diversion connector (not shown in the figure). One end of the diversion connector is provided with an inlet pipe, and the other end is provided with multiple sets of outlet pipes. Each set of outlet pipes is connected to each set of heating branch pipes.

[0038] Specifically, there are five sets of heating branch pipes. The two branch connectors are mainly sleeve structures with closed ends. One end of the sleeve connects to the inlet pipe, and the other end connects to the five sets of outlet pipes arranged in parallel. The five sets of outlet pipes are sealed to the five sets of heating straight pipes one by one. The blocking plate is located between the sleeve and the end of the membrane material pipe, or between the outer wall of the inlet pipe and the membrane material pipe. The flange or joint 8 is located at the end of the inlet pipe.

[0039] By setting the heating oil pipes into multiple sets of heating branches, the heat exchange area between the heating pipes and the film material is increased, thereby improving the heat exchange efficiency.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
