Description

Technical Field

[0001] The invention relates to the technical field of lignite drying machines, in particular to a lignite drying machine. Background Art

[0002] In the process of coal processing, a lot of related equipment is needed, such as crushing equipment, screening machines, ventilation equipment, grinding equipment, dryers, etc. Among them, dryers are extremely widely used. The main part of the dryer is composed of a rotating cylinder slightly inclined to the horizontal line.

[0003] In the prior art, when drying lignite, the lignite enters from the higher end of the cylinder, and under the combined action of the rotating cylinder and gravity, the material comes out from the lower end of the cylinder. The lifting plate on the inner wall of the cylinder continuously scoops up and scatters the material in a spiral manner to achieve heat exchange.

[0004] However, the lifting plate in the prior art is generally directly welded to the inner wall of the cylinder. After long-term use, the lifting plate needs to be replaced when it is worn to a certain extent. Therefore, the old lifting plate needs to be cut off from the inner wall of the cylinder and then a new lifting plate is welded, which is cumbersome to replace. Summary of the invention

[0005] The object of the present invention is to provide a lignite drying machine to solve the problems raised in the above background technology.

One end of the cylinder is also connected to a hot air box through a connecting pipe, and the hot air box transports hot air into the cylinder to dry the lignite in the cylinder.

[0008] Preferably, the bottom of the telescopic block is connected to a first spring, and the first spring can pop the telescopic block out of the first telescopic slot through tension, so that the telescopic block is exposed at the top of the first telescopic slot, thereby facilitating the rapid installation of the lifting plate.

[0009] Preferably, the bottom of the lifting plate is fixedly connected to a T-shaped block, and the T-shaped block can be inserted into a T-shaped slot on the top of the telescopic block through the side of the telescopic block, so that the lifting plate is quickly connected to the telescopic block and the lifting plate is quickly installed on the inner wall of the cylinder.

[0010] Preferably, the cylinder is provided with second telescopic grooves on both sides of the first spring, a second spring is arranged in the second telescopic groove, the other end of the second spring is connected to the closing plate, and the closing plate can be inserted into the slots provided on both sides of the bottom of the lifting plate to hold the lifting plate in telescopic motion.

[0011] Preferably, a plurality of pull rods are provided on the inner top of the closing plate, and pulling the pull rods can cause the closing plate to squeeze the second spring, shrink the closing plate into the second telescopic groove, and disengage the inner front end of the closing plate from the slot, thereby canceling the clamping of the lifting plate.

[0012] Preferably, the lifting plate is provided with a pull rod groove at the top of the slot, the pull rod groove is parallel to the pull rod, and the pull rod groove can be inserted into the pull rod by pressing by an operator, so that the pull rod groove is connected to the lifting plate.

[0013] Preferably, the lifting plate is provided with a third telescopic groove on the inner side of the pull rod groove, and a top block is provided in the third telescopic groove. The top block can pop out the pull rod from the pull rod groove through the tension of the third spring to prevent the pull rod from being stuck in the pull rod groove, making it inconvenient to drive the closing plate to extend and retract by pulling the pull rod.

[0014] Preferably, the lifting plate is provided with a fourth telescopic groove on the front end side of the pull rod groove, and a fourth spring is arranged in the fourth telescopic groove. The fourth spring is connected to the baffle plate, and the baffle plate can close the pull rod groove through the tension of the fourth spring and hold the pull rod in the pull rod groove to prevent the top block from popping the pull rod out of the pull rod groove.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The present invention proposes a lignite dryer. When installing, a new material lifting plate is installed on the top of the telescopic block through a T-shaped clamping block. Then, the telescopic block is pressed to shrink into the first telescopic groove to prevent the lignite from colliding with the telescopic block and causing wear of the telescopic block. At this time, the closing plate is popped out from the second telescopic groove by the tension of the second spring and inserted into the slots on both sides of the bottom of the material lifting plate, so as to fix the telescopic movement of the material lifting plate and close the first telescopic groove to prevent the lignite from falling into the first telescopic groove. At the same time, the baffle is moved to open the closure of the pull rod groove, and the pull rod is pressed to press the pull rod into the pull rod groove. Then, the fourth spring pops out the baffle through tension to hold the pull rod in the pull rod groove, thereby completing the rapid installation of the material lifting plate and hiding the pull rod groove to prevent the lignite from colliding with the pull rod groove and causing damage to the pull rod groove.
