Description

Technical Field

[0001] The utility model relates to the technical field of hollow blade dryers, in particular to a heating and stirring blade of a dryer. Background Art

[0002] Hollow paddle dryer (dryer) is a stirring type dryer, which mainly uses hollow paddles to dry materials. It has the advantages of small footprint, low energy consumption and large production capacity. It is widely used in food, medicine and chemical industries. The main function of the paddles of the hollow paddle dryer is to rotate through two symmetrically arranged paddles to shear, extrude, stir, disperse and heat the surrounding materials, so that the materials change their positions continuously in the radial direction, thereby mixing. The heat and mass transfer efficiency of the hollow paddle dryer is very high, and it can dry the materials.

[0003] In the prior art, for example, a hollow blade dryer with Chinese patent number CN212006557U includes an inner tube body, an outer tube body, a delivery pipe, a guide plate and a hollow blade. The inner tube body is arranged in the inner cavity of the outer tube body, and the hollow blade is arranged on the outer peripheral wall of the outer tube body. One end of the delivery pipe is connected with the inner cavity of the inner tube body, and the other end of the delivery pipe passes through the inner tube body and the outer tube body and is connected with the inner cavity of the hollow blade. A first through hole that is connected to each other is opened between the hollow blade and the outer tube body, and the delivery pipe and the first through hole are respectively arranged at both ends of the hollow blade in sequence along the rotation direction.

[0004] However, during the use of the existing hollow paddle dryer, some materials will corrode the blades, so the blades need to be regularly inspected or replaced. Most of the blades in the prior art are welded to the main shaft, and it is usually impossible to disassemble a certain blade. When damage occurs in a certain position, it often needs to be replaced as a whole, causing great losses. At the same time, it is inconvenient to adjust the number of blades, and it cannot be applied to different materials, and the flexibility is insufficient. Utility Model Content

[0005] The utility model mainly provides a drying machine heating stirring blade which is convenient for disassembling the blade and prevents large losses.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a drying machine heating and stirring paddle, comprising a main shaft, a plurality of paddle assemblies are sequentially installed on the side walls of the main shaft, the main shaft comprises a shaft body, a plurality of mounting grooves are sequentially provided on the side walls of the shaft body, and a plurality of grooves are symmetrically and evenly provided on the inner walls of the mounting grooves, the paddle assembly comprises a blade, a mounting block, a protrusion, a push block, a push plate, an arc plate and a push rod, the top of the mounting block is welded to the bottom of the blade, and a plurality of through holes are symmetrically and evenly provided on both sides of the mounting block, a baffle is movably installed inside the through hole, one side of the baffle is welded to one end of the protrusion, and the other side of the baffle is welded to one end of the push rod, a spring is fixedly connected to the inner wall of one end of the through hole, and one end of the spring is movably connected to one side of the baffle, one end of the push plate is welded to one end of the push block, and the other end of the push plate is welded to one side of the arc plate.

[0007] Preferably, sliders are symmetrically welded on both sides of the push block, and sliding grooves are symmetrically opened on the inner side of the mounting block. When the arc plate is pushed, the push plate is pushed toward the inside of the shaft body, and the sliders slide along the sliding grooves, so that the push block can be stably moved into the inside of the mounting block.

[0008] Preferably, a plurality of bottom grooves are sequentially formed on the side wall of the shaft body, and a clamping groove is formed at one end of the bottom groove, and the clamping groove can be clamped and fixed with the arc plate to prevent the arc plate from moving into the shaft body.

[0009] Preferably, threaded holes are symmetrically provided at both ends of the slot, and two end covers are symmetrically fixedly installed at both ends of the shaft body. Bolts can be used to fix the arc plate to the slot of the shaft body through the threaded holes, so as to facilitate the fixing of the arc plate.

[0010] Preferably, one end of the arc plate is engaged with the inner wall of the slot, and the thickness of the push block is greater than the thickness of the push plate. When the push block is moved into the mounting block, the push block can touch multiple push rods and squeeze the multiple push rods to both sides, thereby moving the protrusion out of the through hole.

[0011] Preferably, the push block is slidably connected to the inner wall of the slide groove via a slider, and the blade is wedge-shaped. The slider and the slide groove can make the push block and the mounting block more stable, thereby enhancing the stability of the mounting block and the blade.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, when the blade assembly needs to be installed, the mounting block is placed on the mounting groove. After placement, the arc plate and the push plate are pushed, and the push block squeezes the multiple push rods to both sides until the protrusion moves out of the through hole and presses in the groove, and then the arc plate is fixed to the slot of the shaft body through the threaded hole by bolts, so that the mounting block is fixed in the mounting groove of the shaft body. When the blade assembly needs to be disassembled, it is only necessary to pull the arc plate outward, the push block moves out of the mounting block, and the protrusion returns to the inside of the through hole under the pulling force of the spring, so that the blade assembly can be installed and disassembled quickly and conveniently, making the disassembly of the blade relatively simpler and more convenient, saving time, and facilitating the maintenance work of the blade by the staff.

[0014] 2. In the utility model, the cooperation between the main shaft and the blade assembly facilitates the regular inspection or replacement of damaged blades. When a blade at a certain position is damaged, the individual blade assembly can be disassembled and replaced without replacing the entire assembly, thereby reducing losses. At the same time, the number of blades can be adjusted according to the mixing requirements of different materials, thereby enhancing the flexibility of the device. BRIEF DESCRIPTION OF THE DRAWINGS

When the arc plate 26 is pushed, the push plate 25 is pushed toward the inner side of the shaft body 11, and the sliders 27 slide along the slide grooves 28, so that the push block 24 can be stably moved to the inside of the mounting block 22.

[0025] like Figure 3 As shown, the side wall of the shaft body 11 is sequentially provided with a plurality of bottom grooves 15 , and one end of the bottom groove 15 is provided with a clamping groove 16 , which can be clamped and fixed with the arc plate 26 to prevent the arc plate 26 from moving into the shaft body 11 .

[0026] like Figure 2 and Figure 3 As shown, threaded holes 17 are symmetrically provided at both ends of the slot 16, and two end covers 12 are symmetrically fixedly installed at both ends of the shaft body 11. Bolts can be used to fix the arc plate 26 on the slot 16 of the shaft body 11 through the threaded holes 17, so as to facilitate the fixing of the arc plate 26.
