[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A hot air drying device for a honeycomb ceramic integral catalyst includes: a heater, an induced draft fan, and a drying chamber, wherein the air outlet of the heater is connected to the air inlet of the induced draft fan, and the air outlet of the induced draft fan is connected to the air inlet of the drying chamber. The drying chamber includes a lifting mechanism, a barrel body, and a barrel cover disposed above the barrel body. The lifting mechanism can move the barrel cover to and away from the barrel body. The air inlet of the drying chamber is located on the barrel body, and the air outlet of the drying chamber is located on the barrel cover. The barrel body includes a fixed part and a movable part that can be opened and closed connected to the fixed part. The barrel cover, together with the fixed part and the movable part, can form a cavity for accommodating the honeycomb ceramic integral catalyst.

[0005] Furthermore, the barrel body also includes a duckbill buckle and a hinge. One side of the fixed part is connected to the movable part via the duckbill buckle, and the other side of the fixed part is hinged to the movable part via the hinge.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] This embodiment provides a hot air drying device for a honeycomb ceramic integral catalyst, such as... Figure 1 and Figure 2 As shown, it includes: a heater 1, an exhaust fan 2, and a drying chamber. The air outlet of the heater 1 is connected to the air inlet of the exhaust fan 2 via a flexible hose, and the air outlet of the exhaust fan 2 is connected to the air inlet of the drying chamber. like Figure 1 and Figure 2 As shown, the drying chamber includes a lifting mechanism, a barrel 4, and a barrel cover 5 disposed above the barrel 4. The lifting mechanism can move the barrel cover 5 to contact with and away from the barrel 4. The air inlet of the drying chamber is located on the barrel body 4, and the air outlet of the drying chamber is located on the barrel cover 5. The barrel body 4 includes a fixed part 41 and a movable part 42 that can be opened and closed connected to the fixed part 41. The barrel cover 5 can form a cavity with the fixed part 41 and the movable part 42 to accommodate the honeycomb ceramic integral catalyst. In this embodiment, the heater 1 is an electric heater, and the induced draft fan 2 is a high-temperature induced draft fan. This embodiment discloses a hot air drying device for a honeycomb ceramic monolithic catalyst. A liftable lid 5 surrounds the upper part of the catalyst within a drying chamber. The barrel body 4 is composed of a fixed part 41 and a movable part 42 that is openable and closable with the fixed part 41. This allows the honeycomb ceramic monolithic catalyst with a large aspect ratio to be inserted from the side, rather than using the traditional method of manually raising the bottom of the catalyst and inserting it vertically. This makes the filling process more convenient and labor-saving, improving filling efficiency.

[0020] Specifically, such as Figure 4 and Figure 5 As shown, the barrel body 4 also includes a duckbill buckle 43 and a hinge 44. One side of the fixed part 41 is connected to the movable part 42 through the duckbill buckle 43, and the other side of the fixed part 41 is hinged to the movable part 42 through the hinge 44. The duckbill buckle 43 and the hinge 44 enable an openable and closable connection.

[0021] Specifically, such as Figure 4 and Figure 7 As shown, both the fixed part 41 and the movable part 42 are provided with clamping plates 45. The clamping plates 45 are provided with grooves that match the outline of the honeycomb ceramic integral catalyst (in this embodiment, the honeycomb ceramic integral catalyst is a long strip with a square cross section). The honeycomb ceramic integral catalyst is clamped by the clamping plates 45, and the clamping plates 45 also serve as reinforcing ribs.

[0022] Specifically, such as Figure 9 As shown, the barrel cover 5 includes a large-diameter pipe 51 and a small-diameter pipe 52, which are smoothly connected. The large-diameter pipe 51 is close to the barrel body 4, and the small-diameter pipe 52 is connected to the dust removal equipment through a flexible hose. The small-diameter pipe 52 serves as the air outlet of the drying chamber.

[0023] Specifically, such as Figures 1 to 3 As shown, it also includes a base 6, on which the heater 1, the fan 2, and the fixing part 41 are placed. To save the floor space of the base 6, as shown... Figure 2 As shown, the induced draft fan 2 and the fixing part 41 can be fixed on the base 6, and the heater 1 can be placed above the induced draft fan 2.

[0024] Specifically, such as Figure 1 As shown, a butterfly valve 7 is provided on the pipeline between the air outlet of the induced draft fan 2 and the air inlet of the drying chamber. The butterfly valve 7 is an electric butterfly valve, which controls the opening and closing of the induced draft fan 2 and the drying chamber.

[0025] Specifically, such as Figure 2 and Figure 3As shown, the lifting mechanism includes a cylinder 3, with both ends of the cylinder 3 fixedly connected to the bucket lid 5 and the base 6 respectively (to avoid obstruction, the base 6 is used to support the partial concealment of the cylinder 3), and the cylinder 3 drives the bucket lid 5 to rise and fall. In practical applications, the lifting mechanism also includes a guide rail. The bucket lid 5 is connected to the guide rail via a slider to improve the stability of reciprocating lifting.

[0026] Specifically, such as Figure 4 and Figure 5 As shown, a connecting pipe 46 is fixedly provided at the bottom of the fixing part 41, such as... Figure 8 As shown, a sieve plate 47 is also fixed on the fixing part 41. The sieve plate 47 is located above the connecting pipe 46. The connecting pipe 46 serves as the air inlet of the drying chamber, and the sieve plate 47 is used to support the bottom of the honeycomb ceramic integral catalyst.

[0027] Preferably, a sealing gasket is provided between the barrel body 4 and the barrel lid 5. In this embodiment, the sealing gasket is fixed to the bottom end of the barrel lid 5, and the sealing gasket abuts against the bottom. Figure 4 and Figure 6 The end plates 48 on the fixed part 41 and the movable part 42 shown are designed to reduce hot air leakage.

[0028] In this embodiment, as Figure 1 As shown, it includes two drying chambers, one of which is for standby use, as follows: Figure 3 As shown, the air outlet of the induced draft fan 2 is connected to the air inlet of the drying chamber through a pipe and a tee 8. When drying the honeycomb ceramic catalyst in one drying chamber, the operator takes out the honeycomb ceramic catalyst in the other drying chamber and fills it with a new honeycomb ceramic catalyst (after the lid 5 is raised, the barrel 4 is opened through the duckbill buckle 43, the honeycomb ceramic catalyst is taken out from the side, and then a new honeycomb ceramic catalyst is put in. The barrel 4 is closed through the duckbill buckle 43, and the lid 5 falls down to complete the filling). This cycle is repeated to achieve continuous operation.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
