Embodiment 1

[0019] refer to figure 1 The structure of the object to be regulated by the method of the present invention is to include a power mechanism 6 fixedly installed in the support frame 7, the power mechanism 6 is in transmission connection with the moving assembly 5, and the moving assembly 5 passes through the shaft center hole of the spiral drum 2 and is connected at the front end. A fixed component 4 is installed, and a plurality of scrapers 1 are evenly (distributed) installed on the outer surface of the spiral drum 2, and a screen 3 is arranged on the periphery of the scraper 1 at a predetermined distance, and the rear end (fixed end) of the screen 3 is fixedly connected to the support frame 7 .

[0020] The moving component 5 is used as the implementation unit for the axial movement of the screw drum 2, and can move the axial position of the screw drum 2; the fixed component 4 can keep the screw drum 2 at a set position in the axial direction of the moving component 5 , to ...

Embodiment 2

[0027] refer to figure 2 , the installation structure of the adjustment object (drum scraper and screen of the cuttings dryer) includes a drive shaft 12 fixed on the axis of the support frame 7, and a hollow guide block is fixedly installed in the center hole of the front end of the drive shaft 12 through bolt Ⅱ11 10. The outer circle of the transmission shaft 12 is set with a screw drum 2 through the key, and a plurality of scrapers 1 are fixedly installed on the outer surface of the screw drum 2; A plurality of bolts I9 are fixedly connected to the flange 8; in addition, the periphery of the scraper 1 is provided with a screen 3 at a predetermined distance, and the rear end (fixed end) of the screen 3 is fixedly connected to the support frame 7 to ensure that the screen 3 is always in a static state.

[0028] In this structure, the helical drum 2 realizes the axial adjustment along the drive shaft 12 by moving along the direction of the keyway, the flange 8 moves and locate...

Abstract

The invention discloses one method for adjusting the gap between a scraper and a screen of a rock debris drying machine. The method includes the steps that the axial distance of a spiral drum is calculated according to the current positions of the scraper and the screen and the current gap between the scraper and the screen, the screen is detached, and a fixing assembly is loosened; a power mechanism is started, and a moving assembly drives the spiral drum to axially move; the power mechanism is stopped, and the fixing assembly and the screen are installed. The invention further discloses another method for adjusting the gap between the scraper and the screen of the rock debris drying machine. The method includes the steps that the axial distance of a spiral drum is calculated by judging the current positions of the scraper and the screen and the current gap between the scraper and the screen, and the screen, a bolt I and a flange are detached; the spiral drum is manually moved in the direction of a drive shaft key groove, and the spiral drum moves in the axial direction of a drive shaft; then the flange is installed on a hollow guide block, the contact faces of the flange and the spiral drum are tightly attached, the bolt I is screwed up to enable the flange and the spiral drum to be firmly fixed, and finally, the screen is installed on a supporting frame. The methods are simple.

Description

technical field [0001] The invention belongs to the technical field of mechanical control, and relates to a method for adjusting the gap between a scraper of a cuttings dryer and a screen mesh. Background technique [0002] The cuttings dryer is the core equipment of the cuttings recovery system and the key to realize the harmless treatment of cuttings. The gap between the spiral drum scraper and the screen in the dryer is one of the main factors affecting the efficiency and effect of the dryer. Effective adjustment of the gap is an effective way to improve the efficient and reliable use of the dryer. At present, the gap between the spiral drum scraper and the screen in the dryer is mainly achieved by adding gaskets at the bottom of the drum to adjust the position of the drum scraper to change the gap between the drum scraper and the screen. This method is simple and reliable, but , When adding gaskets on the lower side of the drum, the machine must be stopped, and the scre...
