Description

Technical Field

[0001] This utility model relates to the field of paddle dryer technology, specifically to an anti-clogging device for paddle dryers. Background Technology

[0002] A paddle dryer (also known as a paddle-type dryer or hollow paddle dryer) is an indirect heating, stirring-type drying device widely used in the chemical, food, environmental protection, and pharmaceutical industries for drying powdery, granular, and paste-like materials. This paddle dryer primarily uses a heat medium (steam, thermal oil, or hot water) passed through the hollow paddles. Heat is transferred through contact between the paddle walls and the wet material, evaporating moisture. The material is continuously agitated by the paddles to ensure uniform heating.

[0003] Chinese utility model patent CN222578693U discloses an anti-clogging device for a hollow paddle dryer. This device mainly removes material residue from the inner wall of the feed pipe using a scraper and controls the rotation speed of the separating paddle by a drive motor, thereby changing the speed at which the material enters the hollow paddle dryer and preventing the material from entering the dryer all at once and causing blockage. However, since the anti-clogging device relies on a drive motor to control the rotation speed of the separating paddle, even at a slow speed, the material still falls continuously, and blockage can still occur due to slow discharge.

[0004] Therefore, we propose an anti-clogging device for paddle dryers to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide an anti-clogging device for a paddle dryer to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An anti-clogging device for a paddle dryer includes a body and an anti-clogging component. A fixing frame is provided at the bottom of the body, and a top cover is provided at the top of the body. The anti-clogging component is installed on the top cover. The anti-clogging component includes a fixing box, a discharge seat, a feed seat, and an adjusting box. The discharge seat is fixedly installed on the top cover and communicates with the interior of the body. The fixing box is arranged on the discharge seat along the length direction parallel to the body. The feed seat is located above the discharge seat and is fixed on the top surface of the fixing box. An adjusting box is slidably arranged between the inner walls of the fixing box. The adjusting box has a material storage hole, which matches the outlet of the feed seat and the inlet of the discharge seat.

[0008] According to the above technical solution, a speed reducer unit is fixedly installed on the fixed frame, and two meshing transmission gears are rotatably arranged on the end wall of the machine body near the speed reducer unit through a shaft connection. One of the transmission gears is connected synchronously to the output end of the speed reducer unit.

[0009] According to the above technical solution, the anti-blocking component also includes a support plate, which is fixed vertically on the top cover, and the top of the support plate is also connected and fixed to the bottom wall of the fixing box. A rotary motor is fixedly installed on one side wall of the support plate.

[0010] According to the above technical solution, connecting bearings are fixedly installed on the side walls opposite to the discharge seat and the support plate. A screw is rotatably installed between the two connecting bearings, and one end of the screw is connected and fixed to the output end of the rotary motor.

[0011] According to the above technical solution, the anti-blocking component also includes a movable frame. The movable frame is arranged in a "U" shape, and a connecting shaft is fixedly installed on the opposite side walls at both ends of the movable frame. The other end of the connecting shaft is fixed on the side wall of the adjustment box. A screw hole is opened in the middle position of the movable frame, and the screw passes through the screw hole and is engaged with the movable frame through threaded transmission.

[0012] Side holes are provided on the opposite side walls at both ends of the fixed box along its length. Contact sensors are embedded at both ends of the side holes, and the connecting shaft slides through the inner walls of the side holes.

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

[0014] By setting a fixed box, discharge seat, support plate, feed seat, adjustment box, moving frame and screw on the top cover, the screw drives the horizontal movement of the moving frame, so that the adjustment box moves back and forth synchronously between the inner walls of the fixed box as the moving frame moves. This causes the storage hole to reciprocate between the outlet of the feed seat and the inlet of the discharge seat, realizing the function of transferring materials. In addition, it can control the batch of materials to be conveyed one at a time, effectively avoiding the blockage caused by all falling at once. Attached Figure Description

A fixing frame 1 is fixedly installed at the bottom of the body 2, and a top cover 3 is fixedly installed at the top of the body 2 (the body 2 has a main controller, not shown in the figure). A reducer 5 is fixedly installed on the fixing frame 1, and two meshing transmission gears 6 are rotatably arranged on the end wall of the body 2 near the reducer 5 via shaft connection. One of the transmission gears 6 is connected synchronously to the output end of the reducer 5. A drying chamber is provided in the body 2, and two paddle assemblies 21 are rotatably arranged in the drying chamber via paddle shafts. The paddle shafts of the two paddle assemblies 21 are connected synchronously to the two transmission gears 6 respectively. In addition, a discharge pipe is fixedly connected to the outer surface of the body 2.

[0024] It should be noted that the aforementioned reducer unit 5, blade assembly 21, and other structural components of the blade dryer are implemented using existing related technologies, and will not be described in detail in this application.

[0025] The anti-blocking component 4 is installed on the top cover 3. The anti-blocking component 4 includes a fixed box 41, a discharge seat 42, a support plate 43, a feed seat 44, an adjustment box 45, and a moving frame 46.

[0026] The discharge seat 42 is fixedly installed on the top cover 3 and communicates with the inside of the machine body 2. The fixed box 41 is fixedly installed on the top surface of the discharge seat 42 along the length direction parallel to the machine body 2. The feed seat 44 is located on the side above the discharge seat 42 and is fixed on the top surface of the fixed box 41. An adjustment box 45 is slidably arranged between the inner walls of the fixed box 41. The adjustment box 45 is provided with a storage hole 451. The storage hole 451 is matched with the outlet of the feed seat 44 and the inlet of the discharge seat 42.

[0027] The support plate 43 is fixedly installed on the top cover 3 in a vertical position, and the top of the support plate 43 is also connected and fixed to the bottom wall of the fixing box 41. A rotary motor 431 is fixedly installed on one side wall of the support plate 43.

[0028] Connecting bearings are fixedly installed on the side walls opposite to the discharge seat 42 and the support plate 43. A screw 47 is rotatably arranged between the two connecting bearings, and one end of the screw 47 is connected and fixed to the output end of the rotary motor 431.

[0029] The movable frame 46 is arranged in a "U" shape, and a connecting shaft 461 is fixedly installed on the opposite side walls at both ends of the movable frame 46. The other end of the connecting shaft 461 is fixed on the side wall of the adjusting box 45. A screw hole is opened in the middle position of the movable frame 46, and the screw 47 passes through the screw hole and is engaged with the movable frame 46 through threaded transmission.

[0030] Side holes 411 are provided on the opposite side walls at both ends of the fixed box 41 along its length. Contact sensors are embedded at both ends of the side holes 411. The contact sensors and the rotary motor 431 are controlled and adjusted by the electrical signal of the main controller. The connecting shaft 461 slides through the inner wall of the side holes 411.

[0031] When the connecting shaft 461 slides to Figure 2 When the left end of the side hole 411 is shown, the material storage hole 451 of the adjusting box 45 is exactly located at the outlet of the feed seat 44. When the connecting shaft 461 slides to Figure 2 When the right end of the side hole 411 is shown, the material storage hole 451 of the adjusting box 45 is located at the inlet of the discharge seat 42, and the other end of the adjusting box 45 blocks and seals the outlet of the feed seat 44.

[0032] It should also be noted that the "fixed installation / connection" methods involved in the above embodiments are not limited to the conventional methods of "screw / bolt connection, threaded connection or welding", as long as the effect of fixing the two is achieved.

[0033] Working principle: During feeding, the material falls from the feeding seat 44 and is temporarily stored inside it. By starting the rotary motor 431, it drives the screw 47 to rotate, thereby causing the moving frame 46 to move in a straight line under the drive of the screw 47. The moving direction of the moving frame 46 can be changed by changing the output direction of the rotary motor 431. As the moving frame 46 moves, the adjusting box 45 moves back and forth synchronously between the inner walls of the fixed box 41. Thus, the material falling into it is transferred from the outlet position of the feeding seat 44 to the inlet position of the discharge seat 42 through the setting of the storage hole 451. In this way, all the material in the feeding seat 44 can be gradually sent into the machine body 2 for drying through multiple intermittent processes. The dried material is discharged from the discharge pipe of the machine body 2.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
