Description

Technical Field

[0001] The utility model relates to the technical field of cement production, in particular to a device for accurately adding fly ash. Background Art

[0002] The fine ash carried out of the furnace by the flue gas formed after the combustion of coal in the boiler is usually called fly ash, also known as fly ash. Because fly ash is an artificial volcanic ash material, it is called the volcanic ash effect. This effect is widely used in cement ingredients to adjust the performance of cement and change the hydration characteristics of cement. In addition, since fly ash is a non-homogeneous substance, its mineral components are mainly mullite quartz, hematite, carbon particles and glass. Different mineral doping leads to variable fluidity of fly ash. Therefore, it is necessary to use a doping device to mix the fly ash. The fly ash is stored inside the tank and discharged through a pusher and a discharge hopper.

[0003] Patent announcement number CN218537861U discloses a fly ash storage device for construction, which mainly solves the problems of easy agglomeration of fly ash, easy mixing of cement clinker and fly ash, easy confusion in the construction production process, and low environmental performance due to the lack of professional fly ash storage device during the construction process. The device includes a storage unit, a support unit, an ash loading pipeline, a conveying unit, and an ash discharging pipeline; the storage unit includes a tank body and a bag-type dust collector arranged on the top of the tank body; the support unit includes a rigid stable frame supporting the tank body, the tank body is arranged vertically, its outer periphery is fixedly installed in the rigid stable frame, and the upper end extends out of the rigid stable frame; the conveying unit is arranged at the bottom of the tank body and is located in the rigid stable frame, the conveying unit includes a fly ash push bin and a fly ash pneumatic conveying system connected to the fly ash push bin, the feed inlet of the fly ash push bin is connected to the feed outlet arranged at the bottom of the tank body, and the discharge outlet of the fly ash push bin is connected to the ash discharging pipeline.

[0004] Although the prior art CN218537861U has many benefits during use, it still has the following problems: it lacks a structure to break up the fly ash inside the storage tank, which results in the fly ash being gradually piled up densely under the action of natural gravity after being put into storage, resulting in poor fluidity and affecting the smoothness of the removal of the fly ash. Utility Model Content

[0005] The purpose of the utility model is to provide a device for accurately mixing fly ash to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a precise external fly ash mixing device, comprising a storage tank body, a connecting cover and a filter cloth, connecting covers are installed on both sides of the lower end of the inner wall of the storage tank body, a baffle is provided on one side of the inner wall of the connecting cover, a connecting rod is installed on one side of the outer wall of the upper end of the baffle, a connecting pipe is installed on the outer wall of one side of the connecting cover, limiting blocks are installed on the lower ends of both sides of the inner wall of the connecting cover, and pressure relief valves are installed on both sides of the outer wall of the upper end of the baffle.

[0007] When using a precise fly ash mixing device in the technical solution, the material enters the storage tank body through the feed pipe and is stored inside the storage tank body. The material inside the storage tank body can be moved out through the discharge pipe, and the gas enters the connection cover through the connecting pipe. The air pressure pushes the baffle and the sealing gasket to move vertically, so that the stirring rod moves out of the connection cover and enters the storage tank body, thereby achieving the purpose of driving the movement of the material inside the storage tank body. When the air pressure is greater than the set pressure of the pressure relief valve, it will flow to the upper end of the baffle, and the airflow will pass through the filter cloth to the material inside the storage tank body, thereby destroying the fly ash particle clusters.

[0008] Preferably, the connection cover is designed in a rectangular shape, and the connection cover is connected to the interior of the storage tank body.

[0009] Preferably, a feed pipe is inserted and installed on one side of the outer wall of the upper end of the storage tank body, and the feed pipe is connected to the inside of the storage tank body. The material enters the inside of the storage tank body through the feed pipe.

[0010] Preferably, a discharge pipe is plugged and installed on one side of the outer wall of the upper end of the storage tank body, and the discharge pipe is connected to the inside of the storage tank body. The material inside the storage tank body is removed through the discharge pipe.

[0011] Preferably, a filter cloth is provided on one side of the upper end of the inner wall of the connection cover, and the filter cloth is connected to the outer wall of the connection rod. The filter cloth can block the material inside the storage tank body to prevent the material from entering the connection cover.

[0012] Preferably, a sealing gasket is fixedly attached to the outer wall of the baffle, and the sealing gasket is in contact with the inner wall of the connection cover. The sealing gasket ensures the sealing between the baffle and the connection cover.

[0013] Preferably, stirring rods are installed on the outer walls on both sides of the connecting rod, and the stirring rods are located at the upper end of the filter cloth. The stirring rods can push the material inside the storage tank body to move.

[0014] Compared with the prior art, the utility model has the following beneficial effects: the utility model achieves the effect of breaking up the material by arranging a plug, a filter cloth and a stirring rod. The material enters the storage tank body through the feed pipe and is stored inside the storage tank body. The material inside the storage tank body can be moved out through the discharge pipe, and the gas enters the connection cover through the connecting pipe. The air pressure pushes the baffle and the sealing gasket to move vertically, so that the stirring rod moves out of the connection cover and enters the storage tank body, thereby achieving the purpose of driving the material inside the storage tank body to move. When the air pressure is greater than the set pressure of the pressure relief valve, it will flow to the upper end of the baffle, and the air flow passes through the filter cloth to the material inside the storage tank body, destroying the clustering of fly ash particles. The dispersed air can be dispersed between the particles, reducing the friction of the fly ash particles themselves, and improving the dispersibility and fluidity of the fly ash. Through the pulsating flow-aiding effect of the air, the direct molecular force of the dense fly ash is destroyed, the arch is broken, and the fly ash is guaranteed to overcome the friction between the particles under natural gravity, thereby ensuring smooth discharge of the material.
