Detailed Implementation

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0018] Example Reference Figures 1-4 This embodiment of the present invention provides a high-efficiency heavy oil high-temperature heating device for preventing uneven sintering and coking, comprising: The system includes a base 101, a transfer pump 102 fixedly connected to the side wall of the base 101, a suction pipe 103 connected to the side wall of the transfer pump 102, a transfer pipe 104 connected to the side wall of the transfer pump 102, a storage tank 105 connected to the end of the transfer pipe 104, a heating assembly 106 fixedly connected to the side wall of the base 101, a stirring assembly 107 hinged to the side wall of the heating assembly 106, and a feeding assembly 108 connected to the bottom of the heating assembly 106. The heating assembly 106 includes a support leg 106a fixedly connected to the side wall of the base 101, a connecting shell 106b fixedly connected to the side wall of the support leg 106a, an auxiliary seat 106c fixedly connected to the side wall of the connecting shell 106b, a connecting seat 106d fixedly connected to the surface of the connecting shell 106b, a locking seat 106e fixedly connected to the top of the connecting shell 106b, and a heating tube 106f adapted to be installed in the inner cavity of the connecting shell 106b.

[0019] Specifically, the support leg 106a is designed to increase the height of the connecting shell 106b above the ground, which facilitates subsequent material unloading. The heating tube 106f is located at the bottom of the inner cavity of the connecting shell 106b, which facilitates heating of the heavy oil from the bottom and ensures uniform heating of the heavy oil.

[0020] Furthermore, the stirring assembly 107 includes an inner liner 107a movably connected to the inner wall of the connecting shell 106b, a heating ring 107b fixedly connected to the surface of the inner liner 107a, and a latch 107c hinged to the side wall of the inner liner 107a. The stirring assembly 107 also includes a cover plate 107d connected to the side wall of the connecting seat 106d via a bearing, and a motor 107e adapted to be installed on the side wall of the cover plate 107d. The stirring assembly 107 also includes a stirring shaft 107f fixedly connected to the output end of the motor 107e, and a cylinder 107g hinged to the side wall of the cover plate 107d.

[0021] The bottom of the cylinder 107g is hinged to the inner wall of the auxiliary seat 106c. When the cylinder 107g extends or retracts, it pulls the cover plate 107d, ensuring that the cover plate 107d can be opened and closed quickly. At the same time, by controlling the cover plate 107d through the cylinder 107g, it can be ensured that the residual heavy oil will not splash onto the personnel when the device is opened and closed, thus ensuring the personal safety of the staff. The heating ring 107b uses induction heating to heat the inner liner 107a.

[0022] Preferably, the unloading assembly 108 includes a fixed plate 108a fixedly connected to the side wall of the support leg 106a, a transmission rod 108b rotatably connected to the inner wall of the fixed plate 108a, and a first helical gear 108c fixedly connected to the end of the transmission rod 108b. The unloading assembly 108 also includes a second helical gear 108d meshing with the side wall of the first helical gear 108c, and a threaded sleeve 108e fixedly connected to the side wall of the second helical gear 108d. The unloading assembly 108 also includes a lead screw 108f threadedly connected to the inner wall of the threaded sleeve 108e, an unloading tube 108g sleeved on the surface of the threaded sleeve 108e, and a pipe joint 108h communicating with the side wall of the unloading tube 108g.

[0023] It should be noted that the discharge pipe 108g is connected to the bottom of the connecting shell 106b and also passes through the bottom of the inner liner 107a, ensuring that the heavy oil in the inner liner 107a can be quickly discharged during discharge.

[0024] In use, the raw material is placed in the inner liner 107a. The cylinder 107g extends, pushing the cover plate 107d. The cover plate 107d, in conjunction with the connecting seat 106d, moves in a circular motion around the connecting seat 106d as the axis, finally fitting against the side wall of the connecting shell 106b. The latch 107c is activated, engaging the locking seat 106e to lock the cover plate 107d. The heating tube 106f is started to heat the inner liner 107a. The motor 107e is started, driving the stirring shaft 107f to run. The stirring shaft 107f stirs the heavy oil during heating to ensure uniform heating. After the heavy oil heating is complete, the transfer pump 102 runs, transferring the coolant from the storage tank 105 through the transfer pump. The pipe 104 draws in coolant, which, together with the suction pipe 103, discharges the coolant into the inner cavity of the connecting shell 106b to regulate its temperature, ensuring that the temperature of the heavy oil during feeding is not too high and may damage other equipment. During feeding, the transmission rod 108b is turned, which drives the first helical gear 108c to rotate. The first helical gear 108c drives the second helical gear 108d, which in turn drives the threaded sleeve 108e to rotate. The threaded sleeve 108e uses its thread to drive the lead screw 108f to move upward, opening the end hole of the feeding pipe. The pipe joint 108h is then used to connect with other equipment. The raw material enters the pipe joint 108h through the feeding pipe 108g, completing the feeding process.

[0025] In summary, the integrated design achieves efficient control of the entire process of heavy oil heating, stirring, cooling, and feeding. The raised connecting shell 106b of the support leg 106a, combined with the bottom heating pipe 106f, ensures uniform heating of the heavy oil. The inner tank 107a with heating ring 107b and the stirring shaft 107f driven by motor 107e form a dual heating and stirring structure, effectively preventing coking caused by local overheating of the heavy oil. The opening and closing structure of the cover plate 107d controlled by cylinder 107g is not only convenient to operate but also improves operational safety. The helical gear transmission feeding component 108 achieves precise flow control through mechanical linkage. Combined with the coolant temperature control system injected by the transfer pump 102, it ensures stable delivery of high-temperature heavy oil and avoids the risk of thermal damage to the equipment. Through the coordinated use of various components, while ensuring heating efficiency, it comprehensively optimizes the anti-coking performance, operational safety, and thermal energy utilization rate, making it particularly suitable for industrial-grade heavy oil processing scenarios that require precise temperature control.
