Description

Technical Field

[0001] This application relates to the field of chemical technology, and in particular to a rotary heating device. Background Technology

[0002] In the field of chemical technology, rotary heating equipment is widely used in key process links such as catalytic reaction, material drying, component preheating, and chemical reaction promotion due to its core advantages of enabling continuous tumbling and uniform contact reaction environment of materials during the heating process. It is especially frequently used in the heating treatment of granular catalysts and is one of the important pieces of equipment to ensure the efficiency of chemical production and the stability of product quality.

[0003] The relevant technology can be found in announcement number CN208038039U, which discloses a rotary reactor device for hydrofluoric acid production, including a converter cylinder, a first hot air jacket, a reinforcing structure, a second hot air jacket, and a transmission mechanism. The first hot air jacket is sleeved in the middle of the converter cylinder. The reinforcing structure includes vertical ribs and reinforcing rings. The vertical ribs are located on the outside of the converter cylinder, and the reinforcing rings are located on the outside of the vertical ribs. There are two reinforcing structures, which are respectively located at the front and rear ends of the converter cylinder. There are two second hot air jackets, which are respectively located on the outside of the reinforcing structures. The transmission mechanism is sleeved on the outside of the second hot air jacket. A heat insulation buffer is provided between the transmission mechanism and the second hot air jacket.

[0004] Although the aforementioned reactors employ multiple hot air jackets to ensure heating at both the beginning and end, the existing equipment lacks auxiliary operation functions after heating is stopped, resulting in insufficient utilization of waste heat and uneven material cooling. After the furnace stops heating, the granular catalyst still needs to be moderately agitated to ensure uniform heat transfer and gradual cooling, in order to avoid localized heat accumulation that could damage the catalyst's activity.

[0005] To address the aforementioned problems, this invention proposes a rotary heating device that can shake the granular catalyst in the reactor before, during, and after heating, thereby improving the heating efficiency of the granular catalyst. Utility Model Content

[0006] To address the shortcomings of the prior art and improve the heating uniformity and efficiency of particulate catalysts throughout the entire process, this application provides a rotary heating device.

[0007] This application provides a rotary heating device, characterized in that it includes:

[0008] The workbench has multiple sets of support seats symmetrically arranged on its upper surface along its preset central axis;

[0009] A rotating support assembly is provided on a workbench and includes a support plate provided above multiple sets of support seats. One end of the support plate is rotatably connected to the outermost set of support seats closest to the edge of the workbench via a connector. The lower surface of the support plate corresponds to the position of the other sets of support seats and forms a mutual abutting fit with the end face of the corresponding support seat.

[0010] A heating furnace is mounted on a rotating support assembly, with the furnace base fixedly connected to the support plate.

[0011] A reactor assembly is located inside a heating furnace and is used to carry the reactants. The non-drive end of the reactor assembly is slidably connected to the inner wall of the heating furnace, and the end of the reactor assembly away from the heating furnace extends outward and is fixedly provided with a handle.

[0012] A rotary power assembly is mounted on a rotary support assembly and is connected to the reactor assembly for driving the reactor assembly to rotate around a preset axis.

[0013] Optionally, an electrical control cabinet is fixedly installed under the workbench. The electrical control cabinet is electrically connected to the heating furnace and the rotary power component, respectively, and is used to control the heating temperature of the heating furnace and the rotation parameters of the rotary power component. Universal casters are installed at the four corners of the bottom of the electrical control cabinet for easy movement.

[0014] Optionally, multiple sets of shock-absorbing pads are provided between the lower surface of the support plate and the other sets of support seats. The shock-absorbing pads are located on the side of the support plate and are tightened by tightening bolts. The shock-absorbing pad corresponding to the outermost set of support seats closest to the edge of the table is fixedly connected to its corresponding support seat. The remaining shock-absorbing pads are made to abut against the upper surfaces of the other sets of support seats by the weight of the support plate itself.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] This invention, through the cooperation between the rotating support assembly and the worktable, allows for dynamic horizontal shaking and position adjustment of the granular catalyst within the reactor before, during, and after heating. The rotating power assembly drives the reactor components within the heating furnace, ensuring uniform vertical heating of the granular catalyst throughout the entire process. This promotes uniform distribution of the granular catalyst throughout the entire process cycle, enhancing the contact between the material and the heat field, improving heat exchange efficiency and heating uniformity, thereby increasing heating efficiency. Furthermore, after heating stops, the continuous and uniform transfer and gradual release of residual heat across the entire surface prevents catalyst activity degradation caused by localized overheating, significantly improving the quality stability of the granular catalyst.

Detailed Implementation

[0024] The present application will be further described in detail below with reference to all the accompanying drawings.

[0025] This application discloses a rotary heating device.

[0026] Reference Figure 1 A rotary heating device includes: a worktable 1, a rotary support assembly 3, a heating furnace 4, a reaction furnace assembly 5, and a rotary power assembly 6.

[0027] Reference Figure 1 Workbench 1, with multiple sets of support seats 2 symmetrically arranged on the upper surface of workbench 1 along its preset central axis;

[0028] The rotating support assembly 3 is disposed on the workbench 1 and includes a support plate 31 disposed above multiple sets of support seats 2. One end of the support plate 31 is rotatably connected to the outermost set of support seats 2 closest to the edge of the workbench via a connector. The lower surface of the support plate 31 corresponds to the position of the other sets of support seats 2 and forms a mutual abutting fit with the end face of the corresponding support seat 2.

[0029] The heating furnace 4 is mounted on the rotating support assembly 3, and the base of the heating furnace 4 is fixedly connected to the support plate 31.

[0030] The reactor assembly 5 is located inside the heating furnace 4 and is used to carry the reaction materials. The non-drive end of the reactor assembly 5 is slidably connected to the inner wall of the heating furnace 4. The end of the reactor assembly 5 away from the heating furnace 4 extends outward and is fixedly provided with a handle 51.

[0031] Rotary power assembly 6 is mounted on rotary support assembly 3. Rotary power assembly 6 is connected to reactor assembly 5 for driving reactor assembly 5 to rotate around a preset axis.

[0032] The workbench 1 provides the installation foundation, and the symmetrically arranged support bases 2 provide stable support for the rotating support assembly 3. The structure of the support plate 31 of the rotating support assembly 3, which is rotatably connected at one end and abuts against the support base 2 at the other end, not only achieves reliable load-bearing for the heating furnace 4 and the reactor assembly 5, but also allows the equipment to be lifted or lowered through the handle 51 on the reactor assembly 5, making it easy to control the position of the catalyst to be heated inside the reactor assembly 5, and providing structural flexibility for equipment maintenance or operation. The heating furnace 4 provides a heating environment for the material inside the reactor assembly 5. The reactor assembly 5 carries the material and its non-transmission end is slidably connected to the inner wall of the heating furnace 4. With the help of the rotating power assembly 6, it is driven to rotate around a preset axis. It can achieve uniform shaking of the material before, during and after heating by continuous rotation, which solves the problems of insufficient utilization of material waste heat and poor cooling uniformity in the prior art, and improves heating efficiency and material processing effect.

[0033] Reference Figures 1 to 3 An electrical control cabinet 7 is fixedly installed under the workbench 1. The electrical control cabinet 7 is electrically connected to the heating furnace 4 and the rotary power component 6, respectively, and is used to control the heating temperature of the heating furnace 4 and the rotation parameters of the rotary power component 6. The four corners of the bottom of the electrical control cabinet 7 are equipped with casters 8 for easy movement. The electrical control cabinet 7 is set under the workbench 1 to achieve precise control of the heating temperature of the heating furnace 4 and the rotation parameters of the rotary power component 6, so as to meet the specific heating and rotation requirements of different processes. The casters 8 at the bottom of the electrical control cabinet 7 enhance the mobility of the equipment and improve the adaptability and practicality of the equipment in different working conditions.

[0034] Reference Figures 1 to 3Multiple sets of shock-absorbing pads 9 are provided between the lower surface of the support plate 31 and the other sets of support seats 2. The shock-absorbing pads 9 are located on the side of the support plate 31 and are tightened by bolts. The shock-absorbing pad 9 corresponding to the outermost set of support seats 2 closest to the edge of the tabletop is fixedly connected to its corresponding support seat 2. The remaining shock-absorbing pads 9 are made to abut against the upper surfaces of the other sets of support seats 2 by the weight of the support plate 31. In use, the operator will tighten all shock-absorbing pads except for the shock-absorbing pad 9 corresponding to the outermost set of support seats 2 closest to the edge of the tabletop and its corresponding support seat 2. The shock absorber 9 and its corresponding support 2 are mutually abutted. When the rotating support assembly 3 is lifted, the operator can control the angle of the shock absorber 9 by tightening or loosening the tightening bolts to ensure that the contact surfaces of the shock absorber 9 and the support plate 31 are parallel to each other. By setting the shock absorber 9 between the lower surface of the support plate 31 and the support 2, the shock absorber 9 is made to abut against the support 2 by the weight of the support plate 31. This can effectively buffer the vibration generated when the equipment is running and when the rotating support assembly 3 is lifted and lowered, reduce the wear of the equipment components by vibration, reduce operating noise, and improve the overall stability and service life of the equipment.

[0035] Reference Figures 1 to 3 The rotating power assembly 6 includes a power source 61 and a transmission component 62. The power source 61 is a stepper motor or a servo motor, and the transmission component 62 is a coupling, a gear transmission mechanism, or a belt transmission mechanism. The power source 61 is fixedly connected to one end of the reactor assembly 5 through the transmission component 62 to output stable rotating power. It is clear that the power source 61 is a stepper motor or a servo motor, which can provide stable and precisely controllable rotating power. The transmission component 62 adopts a coupling, a gear transmission mechanism, or a belt transmission mechanism to ensure that the power of the power source 61 is efficiently transmitted to the reactor assembly 5, so as to achieve precise control of the rotation speed and rotation angle of the reactor assembly 5, and ensure that the material can be evenly shaken according to the process requirements at different processing stages, thereby improving the controllability of material processing.

[0036] Reference Figures 1 to 3 The rotating support assembly 3 includes a bearing housing 32 and a bearing 33. The bearing housing 32 is fixed on the support plate 31, and the bearing 33 is embedded in the bearing housing 32. The inner ring of the bearing 33 is interference-fitted with the end of the reactor assembly 5 near the power source 61 to reduce the frictional resistance when the reactor assembly 5 rotates. The structure of the bearing housing 32 being fixed to the support plate 31 and the bearing 33 being embedded in the bearing housing 32 with the inner ring interference-fitted with the reactor assembly 5 can significantly reduce the frictional resistance when the reactor assembly 5 rotates, ensure its smoothness and stability of rotation, reduce power loss, and at the same time avoid radial shaking when the reactor assembly 5 rotates, ensuring that the material is evenly turned over during rotation, further improving the shaking effect and equipment operating efficiency.

[0037] Reference Figures 1 to 3The workbench 1 is detachably slidably connected with a protective cover for heat insulation and dust prevention. The protective cover improves the safety of operators and provides dust protection for the equipment when not in use, thereby extending the service life of the device.

[0038] The working principle of a rotary heating device according to an embodiment of this application is as follows: During operation, the workbench 1 is first used as the installation base. Multiple sets of support seats 2 symmetrically arranged along the preset central axis provide stable support for the rotary support assembly 3. The electrical control cabinet 7 under the workbench 1 is pre-powered on for self-test and sets the heating temperature of the heating furnace 4 and the rotation parameters of the rotary power assembly 6. One end of the support plate 31 of the rotary support assembly 3 is rotatably connected to the outer support seat 2, and the other end is positioned in conjunction with the other support seats 2 through the shock-absorbing pad 9. At the same time, the protective cover of the workbench 1, which can be detachably and slidably connected, closes to form a heat-insulating and dust-proof space. The operator places the reactor assembly 5, which is loaded with materials, into the heating furnace 4, and lifts the rotary support assembly 3 by the handle 51 or the support plate 31 to adjust the internal structure of the reactor assembly 5. The position of the material ensures that its non-transmission end slides against the inner wall of the heating furnace 4 and that its transmission end is reliably connected to the rotating power component 6. During the core working stage, the electrical control cabinet 7 drives the heating furnace 4 to heat up to the preset value, while controlling the rotating power component 6 to drive the reaction furnace component 5 to rotate around the preset axis. This achieves the following: the material is pre-shaken before heating, the material is continuously turned over and heated evenly during heating, and the material is turned over and cooled evenly in the residual heat after heating. During this period, the shock-absorbing pad 9 absorbs the vibration of the equipment to ensure stability, and the bearing 33 embedded in the bearing seat 32 in the rotating support component 3 reduces rotational friction loss and limits radial sway. After the work is completed, the electrical control cabinet 7 controls the heating furnace 4 and the rotating power component 6 to stop running. If it is necessary to change the working condition, the equipment can be moved by using the casters 8 at the bottom of the electrical control cabinet 7.

[0039] In summary, through the synergistic effect of each component, the device achieves uniform heating while simultaneously ensuring that the material inside the reactor assembly 5 is thoroughly shaken through the dual action of lifting the support plate 31 and driving the reactor assembly 5 to rotate, thereby improving working efficiency.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
