Description
Technical Field
[0001] The utility model belongs to the technical field of fertilizer production, and in particular relates to a rotary drying machine. Background Art
[0002] In the fertilizer production process, after being granulated by the granulator, the finished product still contains moisture, so it needs to be placed in a dryer for drying. For the drying of large amounts of materials, large drum dryers are currently used. The dryer uses steam heating or electric heating to heat the rotating fixed part, and the drum adopts an inclined design, with one end rotating and connected to the feed port, and the other end rotating and connected to the discharge port. The material is heated and dried and then sent out from the discharge port.
[0003] However, the existing rotary dryers have a common problem. Since the material is relatively moist, it is easy to clump and stick to the inner wall of the dryer after entering the dryer, which results in low drying efficiency and problems with material drying quality. Utility Model Content
[0004] In view of the above-mentioned shortcomings, the purpose of the utility model is to provide a rotary dryer, which solves the problem in the prior art that materials are easily agglomerated and adhered to the inner wall of the dryer when drying materials.
[0005] In order to achieve the above purpose, the technical solution provided by the utility model is:

[0007] By adopting the above-mentioned structural design, a striking mechanism is arranged on the outside of the drying drum. When the striking mechanism is located directly above the drying drum during rotation, the gravity ball in the sleeve falls downward and strikes the surface of the drying drum, thereby vibrating the sticky or agglomerated materials inside and dispersing the materials. At the same time, a turning plate is provided inside the drying drum, which can turn the materials during rotation, further reducing the problem of material agglomeration or stickiness.
[0008] As a further improvement, the sleeve is a "7"-shaped structure, and one end is welded and fixed to the outer surface of the drying drum.
[0009] With the above structural design, the sleeve is designed so that when the drying drum is rotated to the upper position, the gravity ball arranged in the sleeve can freely fall from the bent position to hit the surface of the drying drum, thereby increasing the impact force and improving the vibration effect on the drying drum.
[0010] As a further improvement, the drying drum is driven to rotate by a driving mechanism installed on a mounting frame, and a plurality of guide and limit mechanisms are provided on the mounting frame to guide and limit the drying drum during rotation.
[0011] With the above structural design, the driving mechanism arranged below the drying drum drives the drying drum to rotate at a constant speed to ensure the uniformity of material drying. At the same time, the guide and limit mechanism arranged below the drying drum can support, guide and limit the rotating drying drum.
[0012] As a further improvement, the driving mechanism includes a driven gear fixed outside the drying drum and a driving motor installed on a mounting frame. The output end of the driving motor is correspondingly provided with a driving gear, and the driving gear meshes with the driven gear to drive the drying drum to rotate at a uniform speed.
[0013] By adopting the above structural design, the driving force can be ensured to meet the rotation of the large dryer through gear transmission, and the uniform rotation of the drying drum can be ensured at the same time.
[0014] As a further improvement, the guide and limiting mechanism includes a guide ring installed on the drying drum, and the mounting frame is provided with guide components on both sides of the guide ring, which contact and support the guide ring, and the two side edges of the guide ring are provided with limiting components to limit the guide ring.
[0015] As a further improvement, the guide assembly includes a first mounting seat and a guide roller rotatably mounted on the first mounting seat, and the guide roller contacts and supports the guide ring;
[0016] The limiting assembly comprises a second mounting seat and a rotating shaft mounted on the second mounting seat, and a limiting disk is rotatably arranged on the rotating shaft, and the limiting disk is located on both sides of the guide ring to prevent it from being separated from the guide roller.
[0017] With the above structural design, the guide limiting mechanism can play a supporting and guiding role when the drying drum rotates, and can also prevent the guide ring from deviating from the guide drum.
[0018] As a further improvement, the drying drum is tilted at a certain angle and uses steam heating or electric heating to dry the material.
[0019] Compared with the prior art, the beneficial effects of the utility model are:
[0020] 1. The utility model arranges a striking mechanism on the outside of the drying drum. When the drying drum rotates, the striking mechanism is located directly above the drying drum, and the gravity ball in the sleeve falls downward to strike the surface of the drying drum, which can vibrate the sticky or agglomerated materials inside, so that the materials are dispersed, thereby preventing the problems of low drying efficiency and poor material drying quality caused by agglomeration or stickiness of the materials;
[0021] 2. The drying drum of the utility model is provided with a material turning plate inside, which can turn the materials when rotating, further reducing the problem of material agglomeration or sticking. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0029] In order to explain the technical content, structural features, achieved objectives and effects of the present invention in detail, the following is a detailed description in conjunction with the implementation modes and the accompanying drawings.
[0030] The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0031] See also Figures 1 to 4 A rotary dryer comprises a drying drum 2 rotatably mounted on a mounting frame 1, wherein the two ends of the drying drum 2 are respectively provided with a feed port and a discharge port, and the two ends of the drying drum 2 are respectively rotatably fixed on the feed port and the discharge port. When drying the material, the material in the drying drum 2 is dried by steam heating or electric heating. The drying drum 2 is arranged to be inclined at a certain angle, which can ensure that the dried material is smoothly sent out. A plurality of striking mechanisms 3 are arranged on the outside of the drying drum 2, and the striking mechanisms 3 include a sleeve 3a and a gravity ball movably arranged in the sleeve 3a. The gravity ball strikes the drying drum 2 with free fall after the drying drum 2 moves to the upper side, and the material that is agglomerated or stuck to the inner wall can be tensely vibrated and dispersed, thereby improving the drying quality of the material. A plurality of flipping plates 2a are arranged in the drying drum 2, which can flip the material when the material rotates to prevent the material from rotating against the inner wall of the drying drum 2, thereby further improving the drying effect.
[0032] In this embodiment, the striking mechanism 3 is arranged in a ring shape along the drying drum 2, thereby ensuring that the surface of the drying drum 2 is struck at uniform intervals during the rotation process.
[0033] Please continue reading Figure 1 In this embodiment, the sleeve 3a is a "7"-shaped structure, and one end is welded and fixed to the outer surface of the drying drum 2. The shape design of the sleeve 3a can ensure that when it is above the drying drum 2, the gravity ball can hit the drying drum 2 in a free-falling manner from the bent position, rather than sliding along the inner wall of the sleeve 3a to hit, so that the design can increase the impact force and thus improve the vibration effect.
[0034] Please continue reading Figure 2 and Figure 3The drying drum 2 is driven to rotate by a driving mechanism 4 mounted on the mounting frame 1, and a plurality of guide and limit mechanisms 5 are provided on the mounting frame 1 to guide and limit the drying drum 2 during rotation. Specifically, the driving mechanism 4 includes a driven gear 4a fixed to the outside of the drying drum 2 and a driving motor 4b mounted on the mounting frame 1, and a driving gear 4c is correspondingly provided at the output end of the driving motor 4b, and the driving gear 4c meshes with the driven gear 4a to drive the drying drum 2 to rotate at a constant speed.
[0035] The guide and limit mechanism 5 comprises a guide ring 5a mounted on the drying drum 2, and the mounting frame 1 is provided with guide components 5b on both sides of the guide ring 5a, which are in contact with and support the guide ring 5a, and the two sides of the guide ring 5a are provided with limit components 5c to limit the guide ring 5a. The guide component 5b comprises a first mounting seat 51b and a guide roller 52b rotatably mounted on the first mounting seat 51b, and the guide roller 52b is in contact with and supports the guide ring 5a; the limit component 5c comprises a second mounting seat 51c and a rotating shaft 52c mounted on the second mounting seat 51c, and a limit plate 53c is rotatably arranged on the rotating shaft 52c, and the limit plate 53c is located on both sides of the guide ring 5a to prevent it from being separated from the guide roller 52b.
[0036] The working principle of the utility model is as follows:
[0037] The material enters the drying drum 2 from the feed port, and the drying drum 2 is driven to rotate at a constant speed by the driving motor 4b. At the same time, the guide and limit mechanism 5 guides and supports the rotating drying drum 2. When the drying drum 2 rotates, the material in the drying drum 2 turns with its rotation. The turning plate 2a in the drying drum 2 can play an auxiliary role when the material turns over, thereby ensuring the uniformity of drying. After the striking mechanism 3 rotates to the position just above the drying drum 2, the gravity ball in the sleeve 3a moves from the initial position along the sleeve 3a and enters the bending position, and then freely falls and strikes the drying drum 2 to vibrate and break up the agglomerated or sticky materials inside, thereby improving the material drying efficiency and ensuring the material drying quality.
[0038] According to the disclosure and teaching of the above specification, the technicians in the field of the utility model can also change and modify the above implementation. Therefore, the utility model is not limited to the specific implementations disclosed and described above, and some modifications and changes to the utility model should also fall within the protection scope of the claims of the utility model. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the utility model. Other devices that are the same or similar to them are all within the protection scope of the utility model.
