Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of granulating equipment, in particular to a heat conduction oil heat tracing extruding sheet machine. BACKGROUND

[0002] The steel strip sheeting machine is one of the existing devices widely used in the chemical industry. For example, the patent application with publication number CN210096980U configures a sheeting machine head above the starting end of the conveying steel belt, which is used to extrude a sheet shape that meets the process requirements, and then lay it flat on the surface of the continuously moving conveying steel belt.

[0003] Based on the process level, in order to ensure the quality of extrusion, the flowable material needs to be in a relatively uniform sheet shape. Simply relying on the extrusion holes of the extrusion pipe wall cannot guarantee that the flowable material is in a relatively uniform thickness after being extruded. SUMMARY

[0004] The purpose of the present application is to provide a heat conduction oil heat tracing extruding sheet machine, so that the extruded flowable material is in a relatively uniform sheet shape.

[0005] The purpose of the present application is achieved by a heat conduction oil heat tracing extruding sheet machine, which is installed in a granulating equipment, comprising:

[0006] A horizontally extending circular pipe-shaped extruding sheet pipe, the extruding sheet pipe has a material inlet on its upper side;

[0007] A material pipe for conveying flowable material, the material pipe is connected to the material inlet of the extruding sheet pipe;

[0008] Wherein, the extruding sheet pipe is fixed with an intermediate strip-shaped plate extending along the pipe length direction, from the pipe cross-section perspective, the intermediate strip-shaped plate is arranged obliquely, and the two long edges of the intermediate strip-shaped plate leave a gap between the inner wall of the extruding sheet pipe for the flowable material to flow downward, and the lower side of the extruding sheet pipe is provided with a strip-shaped discharge hole extending along the pipe length direction.

[0009] Further, the inner wall of the extruding sheet pipe is fixed with two side strip-shaped plates extending along the pipe length direction, the two side strip-shaped plates are located below the two long edges of the intermediate strip-shaped plate, and leave a gap between the lower plate surface of the intermediate strip-shaped plate for the flowable material to flow.

[0010] The beneficial effects of this invention are as follows: the flowable material first passes through the gap between the long side of the middle strip plate and the inner wall of the extrusion tube, and then through the gap between the middle strip plate and the side strip plate, thus initially processing the flowable material into a sheet shape. Then, the strip-shaped discharge hole allows the flowable material to flow downward out of the extrusion tube in a sheet shape with a relatively uniform thickness. By combining the two gaps and the discharge hole mentioned above, the extruded flowable material is in a state of relatively uniform thickness, improving the extrusion quality and ensuring the smooth progress of subsequent processes.

[0012] Figure 2 It is a schematic diagram of the extended shape of the heat tracing pipe after the extruded tube is unfolded and the flow path of the heat transfer oil.

[0013] Figure 3 This is a schematic diagram showing the connection between the heat transfer oil inlet pipe and the material pipe.

[0014] Figure 4 This is a simplified cross-sectional view of the extrusion tube. Detailed Implementation

[0015] The following is in conjunction with the appendix Figures 1-4 The present invention will be further illustrated by specific embodiments. The flowable substance mentioned in this embodiment can be of many kinds, such as molten sulfur (or other substances), but since the point of invention is not about flowable substances, the type of flowable substance is not limited here.

[0016] like Figure 1 , 4 As shown, a heat-conducting oil-heated extruder is installed in a granulation device and includes:

[0017] A horizontally extending cylindrical extrusion tube 2, the extrusion tube 2 having a material inlet 2a located on its upper side;

[0018] Material pipe 1 is used to transport flowable substances. Material pipe 1 is connected to material inlet 2a of extrusion pipe 2.

[0019] The extrusion tube 2 has a fixed intermediate strip plate 3 extending along its length. From the perspective of the tube cross-section, the intermediate strip plate 3 is arranged at an angle. There is a gap between the two long sides of the intermediate strip plate 3 and the inner wall of the extrusion tube 2 to accommodate the downward flow of the flowable material. This gap is a strip-shaped slit extending along the length of the tube (this gap can be 3-4mm or other sizes, depending on the specific type of flowable material and project requirements). The extrusion tube 2 has a strip-shaped discharge hole 2b extending along the length of the tube on its lower side, so that the flowable material flows down in a relatively uniform sheet-like form and spreads on the continuously moving conveyor belt below.

[0020] In order to optimize the structure configuration, the material inlet 2a and the discharge hole 2b are located in the middle of the extrusion tube 2.

[0021] As a preferred solution, two side strip plates 4 extending along the length of the extrusion tube 2 are fixed to the inner wall of the extrusion tube 2, the two side strip plates 4 are located below the two long edges of the middle strip plate 3 and leave a gap between the lower plate surface of the middle strip plate 3 to accommodate the flow of the flowable material, the gap is a strip-shaped gap extending along the length of the extrusion tube 2 (the gap can be 3-4 mm, or other sizes, depending on the type of flowable material and project requirements).

[0022] As shown in Figure 1 , the flowable material enters the extrusion tube 2 through the material inlet 2a on the upper side of the material pipe 1, and then the flowable material flows from the cavity part above the middle strip plate 3 to the cavity part below the middle strip plate 3 in the extrusion tube 2, in the process, the flowable material first passes through the gap between the long edge of the middle strip plate 3 and the inner wall of the extrusion tube 2, and then passes through the gap between the middle strip plate 3 and the side strip plate 4, to preliminarily process the flowable material into a sheet shape, and then use the strip-shaped discharge hole 2b to make the flowable material flow out of the extrusion tube 2 in the form of a relatively uniform sheet shape, and fall onto the steel belt below.

[0023] In order to maintain the molten state of the flowable material and achieve better extrusion sheeting effect, a heat conducting oil pipe group for circulating heat conducting oil is fixed to the outer wall of the extrusion tube 2, the heat conducting oil pipe group is connected to a heat conducting oil circulation pipeline (such as the heat conducting oil circulation system with a circulating pump and a heating device disclosed in CN102818366A, which is not limited here), so that the heat conducting oil can flow in the heat conducting oil pipe group and continuously release high heat to the extrusion tube 2, so that the flowable material in the extrusion tube 2 can be kept in a molten state to ensure its fluidity.

[0024] The heat conducting oil pipe group includes:

[0025] The heat tracing pipe 7 extends along the outer wall surface of the extrusion tube 2 in a meandering and zigzag manner, the heat tracing pipe 7 is a heat contact component, the cross section of the heat tracing pipe 7 is C-shaped, so that the heat conducting oil directly contacts the extrusion tube 2 and fully utilizes the heat of the heat conducting oil to continuously heat the flowable material, as shown in Figure 1 、 2 , the heat tracing pipe 7 extends along the outer wall surface of the extrusion tube 2 in a meandering and zigzag manner, so that the heat conducting oil flows along the length of the pipe and changes direction at the zigzag part of the heat tracing pipe 7, the arrangement area of the heat tracing pipe 7 covers the outer wall surface of the extrusion tube 2, and the meandering and zigzag shape of the heat tracing pipe 7 can have several forms, which is not limited here;

[0026] The heat conducting oil leading pipe 5 is provided with a jacket cavity la, one end of the heat conducting oil leading pipe 5 is connected with one end of the heat conducting oil circulating pipeline, and the other end of the heat conducting oil leading pipe 5 is fixedly connected with the material pipe 1 and connected with the jacket cavity la, so that the heat conducting oil releases heat to the flowable material in the material pipe 1, and the flowability of the flowable material in the material pipe 1 is ensured;

[0027] The bypass pipe 6 is connected with one end of the heat tracing pipe 7 and the jacket cavity la of the material pipe 1 respectively;

[0028] The heat conducting oil flow pipe 8 is connected with the other end of the heat tracing pipe 7 and the other end of the heat conducting oil circulating pipeline respectively.

[0029] The heat conducting oil leading pipe 5 and the heat conducting oil flow pipe 8 are respectively provided with a heat conducting oil inlet pipe and a heat conducting oil outlet pipe, and the order can be reversed.

[0030] In the embodiment, the heat tracing pipe 7 is provided with the bypass pipe 6, and the heat conducting oil leading pipe 5 is connected with the jacket cavity la of the material pipe 1. Figures 1-3 As shown in the figure, the heat conducting oil flows in the following order: the heat conducting oil leading pipe 5→the jacket cavity la→the bypass pipe 6→the heat tracing pipe 7→the heat conducting oil flow pipe 8.

[0031] The above is the preferred embodiment of the present application, and various transformations or improvements can be made by those skilled in the art on the basis of the above, and these transformations or improvements should belong to the protection scope of the present application without departing from the general concept of the present application.
