Description

Technical Field

[0001] The utility model relates to the technical field of cement production, in particular to a coal-fired furnace slag addition amount regulating component. Background Art

[0002] In the process of cement production, coal slag is a cheap resource and is used as a cement admixture to ensure the stable incorporation of coal slag, reduce ingredient costs and alleviate the pressure on raw material supply.

[0003] Coal-fired slag has good activity, and various test data meet the standard requirements for cement admixtures. Among them, the activity of coal-fired slag is better than that of powder (volcanic ash), and it can replace powder (volcanic ash).

[0004] In the process of adding coal furnace slag to cement admixture, existing measures usually adopt manual mixing or impeller quantitative mixing. Manual efficiency is low, and when the impeller rotates to feed quantitatively, the material is usually directly introduced into the feeding chamber of the impeller, resulting in a large amount of material weight directly acting on the blades. The rotating impeller has a high working intensity, which makes the impeller very easy to fatigue and damage.

[0005] For this reason, we propose a coal-fired slag addition amount adjustment component to solve the existing problems. Utility Model Content

[0006] The utility model aims to solve the problems existing in the background technology and proposes a coal-fired furnace slag mixing amount regulating component.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a coal-fired furnace slag addition amount adjustment component, comprising a machine platform, a feed chamber, a hopper and a metering chamber, a feed chamber is installed at the upper end of the outer wall of the machine platform, a auger rod is rotatably provided in the feed chamber, a hopper is provided at one end of the upper surface of the feed chamber, a connecting chamber is provided at the other end of the lower surface of the feed chamber, a metering chamber is installed at the bottom end opening of the connecting chamber, and an impeller is rotatably installed in the metering chamber.

[0008] Preferably, a chassis is installed inside the machine, a motor is fixed inside the chassis, and the output end of the motor is connected to the shaft end of the auger rod.

[0009] Preferably, an auxiliary frame is installed on the upper surface of the machine table by bolts, and the upper surface of the auxiliary frame is fixed to the lower surface of the feeding cavity by bolts.

[0010] Preferably, a feed inlet is provided at one end of the upper surface of the feed cavity;

[0011] The bottom opening of the hopper is connected to the interior of the feeding cavity through the feed port;

[0012] A sealing cover is installed at the top opening of the hopper, and a material pipe is installed on the sealing cover;

[0013] A discharge port is provided at the other end of the lower surface of the feeding cavity;

[0014] The top opening of the connecting cavity is communicated with the interior of the feeding cavity through a discharge port.

[0015] Preferably, a support seat is provided on the lower surface of the machine platform;

[0016] There are four support bases in total, and the positions of the four support bases are distributed in a rectangular array on the lower surface of the machine.

[0017] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0018] During use, the coal slag addition amount regulating component of the utility model can guide the coal slag to be added into the hopper through the material pipe, and the coal slag falls into the feeding cavity under the action of gravity. At this time, the auger rod is controlled to rotate, so that the material at one end of the feeding cavity is evenly transported to the other end. At this time, the coal slag falls into the quantitative cavity evenly and appropriately through the connecting cavity. At this time, the impeller in the quantitative cavity is controlled to rotate, so that the coal slag material in the quantitative cavity can be quantitatively guided out and dropped onto the cement mixture below to complete the mixing operation. Furthermore, the rotation speed of the auger rod and the impeller can be controlled to control the mixing amount of the coal slag per unit time.

[0019] The utility model adopts the design of uniform material feeding of the auger, so that the material enters the quantitative cavity uniformly and acts on the impeller, which can greatly reduce the working intensity of the impeller and avoid the influence of the quantitative accuracy on the fatigue damage of the impeller.
