Description

Technical Field

[0001] This utility model relates to the technical field of anti-sticking devices, and in particular to an anti-sticking device for a rotary drum dryer. Background Technology

[0002] Rotary drum dryers are widely used in chemical, food, grain processing, and mineral processing industries. They achieve dehydration and drying by ensuring the material comes into full contact with a heat medium through the rotation of the drum. However, in actual operation, materials can easily adhere to the inner wall of the drying drum due to temperature changes, humidity differences, or their own sticky properties, forming a wall-sticking layer.

[0003] Existing technologies have significant shortcomings in addressing the problem of wall adhesion:

[0004] For example, Chinese patent CN216522995U, entitled "Anti-sticking Device for Dryer," describes an anti-sticking device with a fixed hammer in its striking mechanism. This device can only treat a local area of ​​the drying cylinder, resulting in a limited striking coverage area and an inability to completely remove material adhering to the entire wall. Consequently, there is an urgent need to propose an anti-sticking device for rotary drum dryers to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an anti-sticking device for a rotary drum dryer.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

The tooth grooves mesh with the gear.

[0009] As a further embodiment of this utility model, a geared motor is fixedly installed on the bottom surface of the movable seat, and one end of the drive shaft of the geared motor is fixedly connected to the elliptical frame.

[0010] As a further embodiment of this utility model, the movable seat has a first rectangular groove on each of its two inner sides, and a plurality of lateral limiting wheels are fixedly installed in the first rectangular groove. The movable seat also has a second rectangular groove on its top and bottom surfaces, and a plurality of support wheels are fixedly installed in the second rectangular groove.

[0011] As a further embodiment of this utility model, two limiting baffles are fixedly installed on the bottom surface of the track frame.

[0012] As a further embodiment of this utility model, a support arm is fixedly installed on the top surface of the drive base, the support arm is fixedly connected to the top surface of the track frame, and a PLC controller is fixedly installed on one side of the support arm on the right side, the PLC controller being electrically connected to the geared motor and the drive motor.

[0029] In this embodiment, the drive assembly includes a drive motor 14, which is fixedly mounted on the bottom surface of the movable seat 5. The bottom surface of the movable seat 5 and the drive motor 14 are coaxially provided with a second circular through hole. The drive shaft of the drive motor 14 passes through the second circular through hole and is fixedly sleeved with a gear 13. The bottom of the track frame 4 is provided with a rectangular hole 11. A plurality of tooth grooves 12 are provided on one side of the interior of the rectangular hole 11. The tooth grooves 12 mesh with the gear 13.

[0030] In this embodiment, a reduction motor 17 is fixedly installed on the bottom surface of the movable seat 5. One end of the drive shaft of the reduction motor 17 is fixedly connected to the elliptical frame 7. A first rectangular groove is opened on both sides of the interior of the movable seat 5. Several lateral limiting wheels 18 are fixedly installed in the first rectangular groove. A second rectangular groove is opened on the top and bottom surfaces of the interior of the movable seat 5. Several support wheels 3 are fixedly installed in the second rectangular groove. Two limiting baffles 15 are fixedly installed on the bottom surface of the track frame 4. A support arm 16 is fixedly installed on the top surface of the drive base 1. The support arm 16 is fixedly connected to the top surface of the track frame 4. A PLC controller is fixedly installed on one side of the support arm 16 on the right side. The PLC controller is electrically connected to the reduction motor 17 and the drive motor 14.

[0031] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0032] When the user needs to use the drive base 1, the drive base 1 supports and drives the drying cylinder 2 to rotate. The inner wall of the rotating drying cylinder 2 may be adhered to by material. At this time, the drive motor 14 drives the gear 13 to rotate. The rotating gear 13 meshes with the tooth groove 12. Under the rotational support of the support wheel 3 and the lateral limit wheel 18, the moving seat 5 moves along the outer track of the track frame 4, thereby driving the hammer frame 10 to move laterally. At the same time, the reduction motor 17 is started to drive the elliptical frame 7 to drive the top wheel 8 to rotate. The rotating top wheel 8 presses down on the end of the hammer frame 10, causing one end of the hammer head of the hammer frame 10 to tilt up. Then, when the top wheel 8 moves to the end of the hammer frame 10, the hammer frame 10 falls rapidly under the action of gravity. The falling hammer frame 10 strikes the top outer wall of the drying cylinder 2. Combined with the action of gravity, the material adhered to the inner wall is shaken off. At the same time, it strikes the outer wall of the rotating drying cylinder 2 during the movement, with a wide striking range.

[0033] The outer wall of the drying cylinder 2 is provided with a protective layer. The protective layer can be made of wear-resistant steel plate (bolted for easy replacement) or polyurethane wear-resistant layer, etc., so as to adapt to the hammering action of the hammer frame 10 through its own high wear resistance and impact resistance, and avoid damage to the drying cylinder 2 body due to long-term hammering.

[0034] During production, the weight of the hammer body at the end of the hammer frame 10 can be set according to actual needs. A limit switch can be configured on the track frame 4 to retract the hammer frame 10 in areas where hammering is not required, thus avoiding collision between the hammer frame 10 and the outer support ring of the drying cylinder 2, which would cause travel conflict. At the same time, a limit switch can be configured on one side of the movable seat 5. When the hammer frame 10 moves to the top and contacts the limit switch, it can be detected that the hammer frame 10 is at the top and the rotation of the elliptical frame 7 can be stopped at the appropriate time. The limit switch setting method is an existing mature technology and will not be described in detail. Other similar technologies can also be used to achieve control to avoid conflict. In addition, the hammering area can be manually controlled, which is quite practical.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
