Description

Technical Field

[0001] This utility model relates to the field of roasting equipment technology, specifically to a roasting apparatus. Background Technology

[0002] During catalyst production, high-temperature calcination is typically required to induce corresponding physicochemical reactions in the catalyst precursor, such as the solidification of active components, the formation of crystal structures, and the removal of impurities, thereby obtaining catalyst materials with the desired activity and stability. Currently, common catalyst calcination devices often employ box furnace structures. During calcination, the catalyst is usually placed statically in trays or containers inside the furnace chamber, where temperature conduction and reaction processes are achieved through heating air or thermal radiation within the furnace.

[0003] However, this static roasting method has significant problems in practical use. Since the catalyst does not change position during the roasting process, the temperature field distribution inside the furnace is uneven, and the hot air circulation path is restricted, resulting in differences in the heat received by different parts of the catalyst, thus causing local under-roasting or over-roasting. At the same time, uneven heating may also cause the catalyst to agglomerate, stick together, or have its physical structure destroyed, affecting the consistency and quality stability of the product. Therefore, it needs to be improved. Summary of the Invention

[0004] The purpose of this invention is to provide a roasting apparatus to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A roasting apparatus includes a furnace body, a roasting chamber and a driving chamber within the furnace body, a partition plate between the roasting chamber and the driving chamber, a plurality of rotating rods extending into the roasting chamber from the partition plate within the driving chamber, mounting frames on the rotating rods, mesh cylinders for placing catalysts on the mounting frames, sliding grooves opposite each other on the mounting frames, and sliders that can extend into the corresponding sliding grooves on the mesh cylinders, a plurality of heating tubes on the inner wall of the roasting chamber, and a driving assembly for driving the rotating rods to rotate within the driving chamber.

[0007] Furthermore, the drive assembly includes a fixed plate disposed within the drive cavity, a round rod disposed between the fixed plate and the bottom wall of the drive cavity, a first bevel gear disposed at the end of the rotating rod located within the drive cavity, a second bevel gear disposed on the round rod that meshes with the corresponding first bevel gear, and a motor disposed on the fixed plate for driving the round rod to rotate.

[0008] Furthermore, the mesh cylinder includes a base plate and a ring, with a mesh sheet between the base plate and the ring, and an openable baffle plate at the ring.

[0009] Furthermore, the edge of the baffle is provided with connecting ears, and the end of the slider is provided with a connecting hole. A bolt threaded into the connecting hole is provided on the connecting ear.

[0010] Furthermore, a column is provided at the center of the baffle, and a conical hole is provided at the center of the column.

[0011] Furthermore, the upper top wall and lower bottom wall of the roasting chamber are respectively provided with limiting plates, and limiting grooves are formed between the limiting plates. Vertical plates are provided between the limiting grooves, and tapered rods that can be inserted into corresponding conical holes are provided on the vertical plates. Grip grooves are provided on the vertical plates.

[0012] Furthermore, the furnace body is equipped with an opening and closing door located on the front side of the roasting chamber, and the furnace body is equipped with a blocking plate for sealing the drive chamber.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model uses the rotation of a rotating rod to drive the rotation of a mounting frame, which in turn drives the rotation of a mesh cylinder. This causes the catalyst inside the mesh cylinder to continuously tumble and agitate, which avoids uneven heating caused by the catalyst being statically piled up. This effectively improves the uniformity of calcination and the reactivity of the catalyst, thereby enhancing product quality.

[0015] In this invention, multiple mesh cylinders are arranged from top to bottom in the roasting chamber, which can realize the layered roasting of multiple catalyst batches and improve the processing capacity of the roasting device; at the same time, the mesh cylinders can be quickly disassembled and replaced, which is convenient for the replacement, cleaning and maintenance of different materials.

[0016] In this invention, the tapered rod and the conical hole are connected by a pluggable conical surface. In the inserted state, the tapered rod and the conical hole fit together, which can not only support the net cylinder, but also allow the net cylinder to rotate around the tapered rod, thereby improving the stability and rotational accuracy of the device. When the net cylinder needs to be replaced, the operator can pull out the vertical plate to drive the tapered rod out of the conical hole, thereby disassembling the net cylinder. The structure is simple and the operation is convenient. Attached Figure Description

Detailed Implementation

[0023] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0024] The following is in conjunction with the appendix Figures 1-5 This embodiment will be described in further detail.

[0025] Please see Figures 1-5 The roasting apparatus in this embodiment includes a furnace body 100. The furnace body 100 is provided with a roasting chamber 101 and a driving chamber 102. The roasting chamber 101 and the driving chamber 102 are separated by a partition plate 103, which serves to isolate heat and provide mechanical support.

[0026] The drive chamber 102 is equipped with multiple rotating rods 104, which are mounted on the partition plate 103 via bearings. One end of each rotating rod 104 passes through the partition plate 103 and extends into the roasting chamber 101, while the other end is located inside the drive chamber 102. Each rotating rod 104 is fixedly connected to a mounting frame 105 located inside the roasting chamber 101. The mounting frame 105 is used to support the catalyst container, i.e., the screen. The mounting frame 105 has symmetrical sliding grooves 106 on its opposite side walls. Two sliders 107 are fixedly mounted on the outer surface of the screen. The sliders 107 can be inserted into the corresponding sliding grooves 106 to form a detachable and limited sliding connection, thereby enabling the replacement and fixed positioning of the screen on the mounting frame 105 and enhancing operational convenience.

[0027] A plurality of electric heating tubes 108 are evenly distributed on the inner wall of the calcination chamber 101 to provide a heat source for high-temperature calcination of the catalyst inside the mesh cylinder. Specifically, the electric heating tubes 108 are arranged on both sides of the calcination chamber 101 to heat the catalyst inside the calcination chamber 101.

[0028] In this embodiment, the rotation of the rotating rod 104 drives the mounting frame 105 to rotate, which in turn drives the mesh cylinder to rotate, causing the catalyst inside the mesh cylinder to continuously tumble and agitate. This avoids uneven heating caused by the catalyst accumulating statically, effectively improving the uniformity of calcination and reaction activity, and enhancing product quality.

[0029] In this embodiment, multiple mesh cylinders are arranged from top to bottom inside the roasting chamber 101, enabling layered roasting of multiple catalyst batches and improving the processing capacity of the roasting device. The mesh cylinders can be quickly disassembled and replaced, facilitating the replacement, cleaning, and maintenance of different materials.

[0030] Please see Figures 1-5 In this embodiment, a driving assembly is provided inside the driving cavity 102 to rotate the rotating rod 104. Specifically, the driving assembly includes a fixed plate 200 installed inside the driving cavity 102, which is fixedly connected to the partition plate 103. A round rod 201 is provided between the fixed plate 200 and the bottom wall of the driving cavity 102. The round rod 201 is rotatably mounted via bearings. The round rod 201 is provided with several second bevel gears 203 that mesh with the first bevel gears 202 provided at the end of the rotating rod 104. The first bevel gears 202 are fixedly connected to the end of the rotating rod 104 located inside the driving cavity 102, and the second bevel gears 203 are fixedly connected to the round rod 201. By installing a motor 204 on the fixed plate 200, the motor 204 drives the round rod 201 to rotate. The round rod 201 drives the second bevel gears 203 to rotate, and the second bevel gears 203 drive the first bevel gears 202 to rotate, thereby driving the rotating rod 104 to rotate, realizing the rotational firing of the mesh cylinder.

[0031] Please see Figures 1-5 In this embodiment, the mesh cylinder includes a base 300 and a ring 301, and a mesh 302 connecting the two. The mesh 302 is fixedly connected between the base 300 and the ring 301. The mesh 302 is used to carry catalyst particles and allow hot air to circulate freely. The aperture of the mesh 302 is smaller than the diameter of the catalyst particles to prevent the catalyst from spilling. The ring 301 is provided with an openable baffle 303 to facilitate the filling or emptying of the catalyst.

[0032] Please see Figures 1-5In this embodiment, the edge of the baffle 303 is symmetrically provided with connecting ears 304, and the end of the slider 107 is provided with a connecting hole 305. The connecting ears 304 are threadedly connected to the connecting hole 305 by bolts 306 so as to facilitate the opening and closing of the baffle 303.

[0033] Please see Figures 1-5 In this embodiment, a column 400 is provided at the center of the baffle 303, and a conical hole 401 is formed at the center of the column 400. In order to further fix the position of the mesh cylinder and improve the rotation accuracy, limit plates 402 are respectively provided on the upper and lower inner walls of the roasting chamber 101, and a limit groove is formed between the limit plates 402. A vertical plate 403 is provided in the limit groove, and the vertical plate 403 is slidably connected to the limit groove. A conical rod 404 that can be inserted into the conical hole 401 is fixed on the vertical plate 403, and the conical rod 404 and the conical hole 401 are connected by a removable conical surface. When the vertical plate 403 is installed in the limiting groove, the tapered rod 404 is inserted into the conical hole 401. At this time, the tapered rod 404 and the conical hole 401 fit together, which can not only support the net cylinder, but also enable the net cylinder to rotate around the tapered rod 404, thereby improving the stability and rotation accuracy of the device. When the net cylinder needs to be replaced, the operator can pull out the vertical plate 403 to drive the tapered rod 404 out of the conical hole 401 to disassemble the net cylinder. The structure is simple and the operation is convenient.

[0034] In this embodiment, in order to facilitate manual loading and unloading, the vertical plate 403 is also provided with a gripping groove 405, which makes it easy for the operator to insert or remove the vertical plate 403 into the roasting chamber 101 for positioning or removal.

[0035] Please see Figures 1-5 In this embodiment, the furnace body 100 is provided with an openable door 109 on the front side. When the door 109 is closed, its inner wall can fit against the surface of the vertical plate 403, thereby limiting the vertical plate 403 to prevent it from sliding and further preventing the tapered rod 404 from falling off during use.

[0036] A blocking plate 110 is also provided on the furnace body 100 to seal the drive cavity 102. The blocking plate 110 is provided with heat dissipation holes located at the motor 204 to dissipate heat from the drive cavity 102, thereby improving safety and device lifespan.

[0037] In use, the opening and closing door 109 is first opened, and the vertical plate 403 is removed through the gripping groove 405. After the conical rod 404 is disengaged from the conical hole 401, the baffle plate 303 is removed to open the mesh cylinder. The catalyst to be roasted is placed in the mesh cylinder. After the catalyst is placed in the mesh cylinder, the bolt 306 is connected to the connecting hole 305 to close the mesh cylinder with the baffle plate 303. Then, the vertical plate 403 is reset so that the conical rod 404 is inserted into the conical hole 401 to limit the baffle plate 303. The opening and closing door 109 is then closed. The inner wall of the opening and closing door 109 abuts against the vertical plate 403 to limit the vertical plate 403 and prevent it from sliding. At this time, the motor 204 is started to drive the mesh cylinder to rotate, and the electric heating tube 108 is started to roast the catalyst.

[0038] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
