Description

Technical Field

[0001] The utility model relates to the technical field of cement production, in particular to a high-temperature continuous clinker sampling mechanism. Background Technique

[0002] Cement clinker takes limestone, clay and iron-containing raw materials as the main raw materials, is formulated into raw meal in appropriate proportions, burned to partial or complete melting, and obtained semi-finished products after cooling. In the clinker, the calcium silicate mineral is not less than 66%, and the mass ratio of calcium oxide to silicon dioxide is not less than 2.0. It is of great significance to accurately measure the physical and chemical contents of cement clinker. Under stable conditions, through physical inspection of the clinker, high strength indicates a reasonable batching plan, and low strength indicates that there are unreasonable parts in the plan, and it is necessary to make adjustments. At the same time, as the basis for determining the quality control indicators of cement production, according to the change of clinker quality, the quality control indicators of cement grinding should be adjusted in time.

[0003] Before detection, it is necessary to sample the cement clinker. The existing sampling usually relies on manual sampling one by one at a single detection point, and the sampling efficiency is relatively low.

[0004] For this reason, we propose a high-temperature continuous clinker sampling mechanism to solve the existing problems. Content of the Utility Model

[0005] The purpose of the utility model is to propose a high-temperature continuous clinker sampling mechanism aiming at the problems existing in the background technique.

A support seat is provided on the lower surface of the workbench, a conveyor belt is provided on the upper surface of the workbench, the extension plate is provided at the lower end of the outer wall of the workbench, a hopper is provided on the extension plate, a filter screen is provided in the hopper, a vibration motor is provided on the upper surface of the filter screen, a vacuum pump is provided on the upper surface of the hopper, an extension pipe is movably provided on the workbench, a strip-shaped hole is provided on the lower surface of the extension pipe, and the extension pipe is interconnected with the inside of the hopper through a connecting hose.

[0007] Preferably, columns are welded at equal intervals at the lower end of the outer wall of the hopper, and the bottom ends of the columns are fixed on the upper surface of the extension plate.

[0008] Preferably, a collection tank is placed on the upper surface of the extension plate, the collection tank is directly below the bottom opening of the hopper, and a valve is provided at the bottom opening of the hopper.

[0009] Preferably, a cover plate is fixed at the upper surface opening of the hopper, a vacuum pump is provided on the upper surface of the cover plate, and the suction end of the vacuum pump penetrates through the cover plate and is above the filter screen.

[0010] Preferably, a cylinder is provided at the upper end of the outer wall of the workbench, and the output end of the cylinder is fixed to the outer wall of one end of the extension pipe.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. During the use of the high-temperature continuous clinker sampling mechanism of the present utility model, the device can be installed near the conveyor belt for continuous conveying of cement clinker. At the sampling points of the conveyor belt, multiple such devices are correspondingly arranged. During sampling, connect to an external power supply. At this time, the cylinder works to drive the extension pipe to move downward and approach the cement clinker transported on the conveyor belt. Then, the vacuum pump works, and a negative pressure is generated in the extension pipe through the connecting hose. Under the action of the pressure, the cement clinker is sucked into the extension pipe and then enters the hopper. After the sampling per unit time is completed, control the vibration motor to drive the filter screen to vibrate, so as to shake off the adhered clinker. Then, open the outlet of the hopper, and the cement clinker falls into the collection tank. The present utility model effectively improves the sampling efficiency of the cement clinker at each sampling point and saves labor costs. BRIEF DESCRIPTION OF THE DRAWINGS
