Detailed Implementation

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

[0019] Please see Figure 1-5 This utility model provides a technical solution: a chemical raw material drying device for the commissioning of a chemical plant, comprising a first semi-cylinder 1 and a second semi-cylinder 2, which are connected by hinges to form a complete cylinder. A drying cylinder 3 is placed inside the cylinder, and the top of the drying cylinder 3 is open for feeding chemical raw materials. A discharge port 4 is provided on the lower side of the drying cylinder 3, and a valve 5 is installed on the discharge port 4. The valve 5 is preferably a manual valve for controlling the discharge.

[0020] The inner surfaces of the first semi-cylinder 1 and the second semi-cylinder 2 are provided with heating plates 12 that are attached to the outer surface of the drying cylinder 3. The heating plates 12 are commonly used electric heating plates and are arc-shaped. In addition, the lower side of the drying cylinder 3 and the lower side of the first semi-cylinder 1 and the second semi-cylinder 2 can also be set as inverted cones, and electric heating plates of corresponding shapes are set in the inverted cone parts.

[0021] When two semi-cylinders are combined to form a complete cylinder, the diameter of the opening on the lower side is greater than the maximum length of the discharge port 4 and the valve 5, so as to avoid the first semi-cylinder 1 and the second semi-cylinder 2 being unable to be assembled or affecting the discharge.

[0022] A control switch can be installed on the outer surface of the second semi-cylinder 2 to control the switching of the electric heating plate. A wire groove is provided at the hinge of the first semi-cylinder 1 and the second semi-cylinder 2 for the passage of a wire, allowing the control switch to simultaneously control the heating plates in both semi-cylinders. A corrugated pipe can be installed on the outside of the wire to protect it.

[0023] The drying cylinder 3 consists of two layers, an outer layer and an inner layer. The outer layer can be made of a material with high thermal conductivity, such as aluminum alloy, while the inner layer uses a material with high thermal conductivity that is less likely to react with the raw materials, such as 316L stainless steel (corrosion resistant) coated with polytetrafluoroethylene (PTFE) (anti-adhesion). The specific material to be heated can be selected according to the actual needs.

[0024] This equipment uses a separable drying cylinder 3 to dry raw materials. During heating and drying, the drying cylinder 3 is surrounded and fixed by the first semi-cylinder 1 and the second semi-cylinder 2. Then, the raw materials inside the drying cylinder 3 are heated and dried by the heating plate 12. After drying, if different raw materials need to be dried, the first semi-cylinder 1 and the second semi-cylinder 2 can be opened to remove the drying cylinder 3. Then, another drying cylinder 3 can be placed inside the first semi-cylinder 1 and the second semi-cylinder 2 for drying. The drying cylinder 3 can be quickly replaced to dry different raw materials, avoiding cross-contamination caused by residual materials. It does not require immediate cleaning and can speed up the commissioning process. It is especially suitable for commissioning processes that require drying multiple different raw materials.

[0025] In a preferred embodiment, the drying cylinder 3 is equipped with a stirring mechanism. The stirring mechanism includes an upper fixed frame 9 located on the upper part of the inner side of the drying cylinder 3, a lower fixed frame 8 located on the upper part of the inner surface of the discharge port 4, a stirring rod 6 coaxial with the drying cylinder 3 located between the upper fixed frame 9 and the lower fixed frame 8, and several sets of stirring paddles 7 evenly arranged on the outer periphery of the stirring rod 6. The stirring rod 6 drives the stirring paddles 7 to rotate, thereby stirring the raw materials in the drying cylinder 3.

[0026] The top of the stirring rod 6 extends through the upper surface of the upper fixing frame 9 and is connected to the fixing column 10. The upper surface of the fixing column 10 is provided with a cross-shaped slot 11. A cover plate 13 is hinged to the upper side surface of the first semi-cylinder 1. A reduction motor 14 is installed on the outer surface of the cover plate 13. The reduction motor 14 is electrically connected to the control switch on the second semi-cylinder 2 and is controlled by it.

[0027] The output shaft of the geared motor 14 passes through the side surface of the cover plate 13 and is fixedly connected to the cross-shaped retaining post 15. The retaining post 15 is located at the center of the cover plate 13 and is adapted to the shape of the retaining groove 11, with the groove 11 being slightly larger than the cross-sectional area of ​​the retaining post 15, so that the retaining post 15 can be inserted into the groove 11. The geared motor 14 drives the stirring rod 6 and the stirring paddle 7 to rotate through the retaining post 15, which can stir the raw materials in the drying cylinder 3, making the heating more uniform, improving the drying efficiency, and shortening the trial run time.

[0028] In a further preferred embodiment, a dehumidification pipe 18 is provided on the upper surface of the cover plate 13, and a dehumidification fan 19 is installed on the dehumidification pipe 18. The dehumidification fan 19 is also electrically connected to and controlled by the control switch on the second semi-cylinder 2. When drying chemical raw materials, after the cover plate 13 is closed, the locking pin 15 of the reduction motor 14 engages with the locking groove 11 of the stirring rod 6. The raw materials are heated by the heating plate 12 and stirred by the stirring mechanism. At the same time, the dehumidification fan 19 can be turned on to discharge the water vapor generated during the drying process into the drying cylinder 3 through the dehumidification pipe 18, thereby further improving the drying efficiency.

[0029] The geared motor 14, heating plate 12, and dehumidifying fan 19 are all powered by an external power source, and the control switch of the second semi-cylinder 2 is equipped with a switch corresponding to the geared motor 14, heating plate 12, and dehumidifying fan 19.

[0030] The geared motor 14, heating plate 12, and dehumidifying fan 19 used in this application are all commonly used electronic components in the prior art. Their specific structures, working principles, control methods, and circuit connections are all known technologies and will not be described in detail here.

[0031] In a preferred embodiment, a locking block 17 is provided on the upper surface of the cover plate 13 away from the hinge point with the first semi-cylinder 1, and a buckle 16 corresponding to the locking block 17 is hinged to the upper side surface of the second semi-cylinder 2. After the cover plate 13 is placed on the two semi-cylinders, the buckle 16 can be rotated to lock the locking block 17, thereby fixing the cover plate 13 and pressing the locking post 15 into the locking groove 11, making the connection between the reduction motor 14 and the stirring rod 6 more secure and improving the stability of the stirring and drying process.

[0032] Fixing components, such as buckles 16 and clips 17, can also be provided at the free ends of the first semi-cylinder 1 and the second semi-cylinder 2 to fix the first semi-cylinder 1 and the second semi-cylinder 2 from the side, so that the heating plate 12 fits more closely to the outer surface of the drying cylinder 3 and improves the drying efficiency.

[0033] In a preferred embodiment, two support columns 20 are respectively provided on the lower surfaces of the first semi-cylinder 1 and the second semi-cylinder 2 to support the entire equipment. Simultaneously, the discharge port 4 can be raised to facilitate discharge after drying.

[0034] In a further preferred embodiment, the bottom end of the support column 20 is equipped with rollers 21 and a foot brake 22. These rollers and foot brakes allow for convenient movement and parking of the equipment, improving operational flexibility. Simultaneously, the rollers 21 allow for quick opening of the semi-cylinder to remove the drying cylinder 3, enabling rapid replacement of the drying cylinder 3 when drying various raw materials, further improving work efficiency.

[0035] An optional technical solution involves providing a ball groove on the lower fixed frame 8 corresponding to the bottom end of the stirring rod 6. A ball 23 is rolled within the ball groove, and a spring 24 is positioned between the ball 23 and the bottom surface of the ball groove. The bottom end of the stirring rod 6 contacts the ball 23. Simultaneously, the stirring rod 6 rotates within a through slot on the upper fixed frame 9 and can slide up and down a certain distance. This provides sufficient clearance when the cover plate 13 is on and the retaining post 15 is inserted into the retaining slot 11, preventing the stirring rod 6 from being rigidly mounted and making it difficult to connect to the reduction motor 14. The contact between the bottom end of the stirring rod 6 and the ball 23 during rotation reduces friction.

[0036] A dynamic seal is provided between the bottom end of the stirring rod 6 and the ball groove.

[0037] Optionally, a handle made of heat-insulating material such as ceramic fiber can be installed on the top of the drying cylinder 3 to facilitate the staff to take the drying cylinder 3 when changing the drying raw materials.

[0038] Optionally, a hygrometer, such as the Honeywell HIH-4000 series, with a detection range of 0-100% RH, can be installed inside the drying cylinder 3 in a location where it will not be hit by the agitator 7. This hygrometer is used to detect the dryness of the raw materials. It is powered by a built-in battery located at the discharge port 4, and a display screen can also be installed here to show real-time humidity and other information for operator reference.

[0039] The parts not disclosed in this utility model are all prior art, and their specific structures, materials, and working principles will not be described in detail. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
