Description

Technical Field

[0001] The invention relates to the technical field of dryer blades, and in particular to a blade structure of a hollow blade dryer. Background Art

[0002] The hollow blade dryer is a horizontal stirring dryer based on heat conduction. Since the heat required for drying is indirectly heated by heat conduction, only a small amount of gas is needed to take away the moisture during the drying process, which greatly reduces the loss of the heat taken away by the gas and improves the utilization rate of heat. The hollow blade dryer is an energy-saving drying equipment. It is suitable for drying granular and powder materials, and can also dry paste materials smoothly. During the use of the hollow blade dryer, because some of the dried materials will corrode the blades, it is necessary to regularly inspect the blades. If the blades are worn or corroded seriously, they need to be replaced.

[0003] However, in the prior art, many blades of hollow blade dryers are welded, which makes it very troublesome to replace the blades. The replacement steps are cumbersome and affect the working efficiency of the hollow blade dryer. Therefore, a blade structure of a hollow blade dryer is proposed. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings in the prior art and to propose a paddle structure for a hollow paddle dryer.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a paddle structure of a hollow paddle dryer, comprising a rotating shaft, grooves are provided on both sides of the rotating shaft, and a plurality of limit hooks are welded on the side where the two grooves are close to each other, a pressure box is provided in the groove, a plurality of barrels are welded on the bottom of the pressure box, a spring is welded on the bottom inner wall of the barrel, a telescopic column is slidably installed on the top of the barrel, the bottom of the telescopic column and the top of the spring are welded together, the tops of the plurality of telescopic columns are welded with the same moving plate, sliders are welded at both ends of the moving plate, a partition is welded inside the pressure box, the top and bottom of the partition are respectively welded to the top inner wall and the bottom inner wall of the pressure box, two sliders are respectively slidably connected to the inner wall of one side of the pressure box and one side of the partition, and a pressing block and a driven block are respectively welded on the top of the moving plate.

[0006] Preferably, fixing blocks are welded on both sides of the rotating shaft, and the fixing blocks are located below the pressure box.

[0007] Preferably, a slide groove is provided on the inner wall of one side of the partition close to the slider and the pressure box, the top and bottom of the slide groove are welded with the same slide rod, and the sides away from the two sliders are provided with rod through holes, and the inner wall of the rod through hole is slidably connected to the slide rod.

[0008] Preferably, a through hole is opened on the inner wall of the top of the barrel, a sealing ring is provided on the inner wall of the through hole, and the telescopic column and the sealing ring are slidably connected.

[0009] Preferably, a connecting block is fixedly mounted on the bottom of the telescopic column, and the bottom of the connecting block and the top of the spring are welded together.

[0010] Preferably, two through holes are provided on the top inner wall of the press box, and the pressing block and the driven block respectively pass through the corresponding through holes, extend into the press box and are welded to the top of the movable plate.

[0011] Compared with the prior art, the beneficial effect of the present invention is as follows: when in use, the paddle blade is placed on the top of the fixed block, and then the pressing block is squeezed by hand. The downward movement of the pressing block will drive the movable plate to move downward, and the movable plate drives the sliders at both ends to move downward along the sliding grooves on the inner wall of one side of the partition and the pressure box, and the bottom of the movable plate will squeeze multiple telescopic columns to move downward, and the telescopic column squeezing spring will deform. When the movable plate moves downward, the driven block will also move downward. When the top of the driven block moves to the lowest end of the limit hook and is completely disengaged from the limit hook, the pressure box is pulled away from the limit hook, and then the pressure box is pressed downward. According to the size of the paddle blade, a limit hook with a suitable distance from the fixed block is selected, and the pressure box is pushed in. Finally, the pressing block is released, and the spring returns to its position, which will squeeze the movable plate. Finally, the movable plate will squeeze the driven block upward and tightly clamped with the limit hook, thereby fixing the paddle blade.

[0012] The invention has a simple structure and is easy to use. The locking device is used to fix the blades, which saves time when disassembling the blades and improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Fixed blocks 13 are welded on both sides of the rotating shaft 1, and the fixed blocks 13 are located below the pressure box 4. A slide groove is provided on the inner wall of the side of the partition plate 9 close to the slider 10 and the side of the pressure box 4. The top and bottom of the slide groove are welded with the same slide rod. Rod through holes are provided on the sides away from the two sliders 10. The inner wall of the rod through hole is slidably connected to the slide rod. A through hole is provided on the top inner wall of the barrel 5, and a sealing ring is provided on the inner wall of the through hole. The telescopic column 7 is slidably connected to the sealing ring. A connecting block is fixedly installed at the bottom of the telescopic column 7. The bottom of the connecting block and the top of the spring 6 are welded together. Two through holes are provided on the top inner wall of the pressure box 4. The pressing block 11 and the driven block 12 respectively penetrate the corresponding through holes and extend to the pressure box 4. The box 4 is welded with the top of the movable plate 8. When in use, the paddle is placed on the top of the fixed block 13, and then the pressing block 11 is squeezed by hand.
