Description

Technical Field

[0001] The utility model relates to the technical field of cement production, in particular to a cement proportioning device. Background Art

[0002] Cement: Powdered hydraulic inorganic cementitious material. After adding water and stirring, it becomes a slurry, which can harden in the air or better in water, and can firmly cement sand, stone and other materials together. The early mixture of lime and volcanic ash is very similar to modern lime volcanic ash cement. It is used to cement concrete made of crushed stone. After hardening, it not only has high strength, but also can resist the erosion of fresh water or salt water. For a long time, it has been widely used as an important cementitious material in civil construction, water conservancy, national defense and other projects.

[0003] Cement is made of limestone, clay and iron ore powder ground and mixed in a certain proportion. The mixture is generally called raw material. Then it will be calcined, usually at a temperature of about 1450 degrees, and the product after calcination is called clinker. Then the clinker and gypsum are ground together and mixed in proportion to be called cement.

[0004] When the existing cement proportioning and mixing structure is used, each appropriate amount of components is introduced into the mixing tank by means of a pump, and after being mixed and stirred by the stirring rod in the mixing tank, it falls into the external transmission structure and is transported to the designated location through the transmission structure;

[0005] The proportioning and mixing of cement is large and continuous. The mixing method of the mixing tank will have the problem of small mixing structure width, resulting in low efficiency and discontinuous production. The mixed materials also need another conveying structure for transmission, and the machine occupies more space.

[0006] For this reason, we propose a cement proportioning device to solve the existing problems. Utility Model Content

[0009] Preferably, a feed port is provided on the upper surface of one end of the chute, and the feed port is communicated with the bottom opening of the feeding chamber;

[0010] A discharge port is provided at the bottom of the other end of the chute.

[0011] Preferably, air outlet pipes are equidistantly inlaid on the top of the inner wall of the chute;

[0013] Preferably, a square notch is provided at the bottom end of the inner wall of the chute, and the air-permeable layer is fixed in the square notch;

[0014] An air inlet is inlaid and installed at one end of the air slot.

[0015] Preferably, a feeding wheel is rotatably installed in the feeding chamber;

[0018] The sealing plate is equidistantly inlaid with batching pipes.

[0019] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0020] 1. During the use of the cement proportioning device of the utility model, the powders of various components required for cement production enter the hopper through the proportioning pipe under the action of the pump, and the proportion of each component can be controlled by controlling the conveying power of the pump;

[0021] 2. During this process, the feeding wheel in the feeding chamber works, so as to feed the mixed material in the hopper into the chute at a uniform speed. At this time, the air inlet is connected to the external high-pressure air source, and the air flow enters the air trough, then enters the chute through the air permeable layer, and then blows into the cement material, so that the cement material can be fluidized under the action of wind.
