Description

Technical Field

[0001] This utility model relates to the technical field of ceramic catalyst extrusion molding, and in particular to an integrated ceramic catalyst extrusion molding device for flue gas dust removal and denitrification. Background Technology

[0002] A ceramic catalyst is a catalyst that uses ceramic materials as a support or active component to accelerate or guide the reaction process in a chemical reaction.

[0003] Existing ceramic catalyst extrusion molding technologies, such as the prior art with application number CN201620309587.9, include a base, transmission box, motor, cylinder, screw, hopper and molding die, etc. The material is fed smoothly with the assistance of the vibration device. After the material enters the cylinder, it can be appropriately heated. The material is subjected to uniform force inside the cylinder, and the extrusion pressure is moderate.

[0004] However, the raw materials need to be mixed before extruding ceramic catalysts, and larger particles or impurities can affect the quality of extrusion molding of ceramic catalysts. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an integrated ceramic catalyst extrusion molding device for flue gas dust removal and denitrification, which facilitates the mixing and screening of raw materials, improves the mixing quality, feeding efficiency, and molding quality.

[0006] This utility model discloses an integrated ceramic catalyst extrusion molding device for flue gas dust removal and denitrification, comprising an extrusion molding structure; and further comprising a mixing mechanism, a screening mechanism, a screening drive mechanism, a striking mechanism, and a striking drive mechanism. The mixing mechanism is mounted on the extrusion molding structure, the screening mechanism is mounted on the mixing mechanism, the screening drive mechanism is mounted on the screening mechanism, the striking mechanism is mounted on the extrusion molding structure, and the striking drive mechanism is mounted on the extrusion molding structure. The extrusion molding structure extrudes and molds the raw material, the mixing mechanism mixes the raw material, the screening drive mechanism drives the screening mechanism to screen the mixed raw material, and the striking drive mechanism drives the striking mechanism to strike the extrusion molding structure. The extrusion molding structure extrudes and molds the raw material, the mixing mechanism mixes the raw material, the screening drive mechanism drives the screening mechanism to screen the mixed raw material, improving the quality of the extrusion molding, and the striking drive mechanism drives the striking mechanism to strike the extrusion molding structure, thus improving practicality.

[0007] Preferably, the extrusion molding structure includes an extruder, a molding die, and a feed hopper. The molding die is installed on the extruder, and the feed hopper is installed at the top of the extruder. Raw materials are added into the extruder through the feed hopper, and the extruder extrudes the raw materials into the feed hopper for molding.

[0008] Preferably, the mixing mechanism includes a mixing tank, a stirring shaft, stirring blades, and a first motor. The mixing tank is mounted on the top of the extruder via a bracket. The stirring shaft is rotatably mounted inside the mixing tank, and the stirring blades are mounted on the stirring shaft. The first motor is mounted on the top of the mixing tank, and the output end of the first motor is connected to the stirring shaft. A control valve is provided on the mixing tank. By opening the first motor, the stirring shaft is driven to rotate, which in turn drives the stirring blades to rotate, thus fully mixing the raw materials.

[0009] Preferably, the screening mechanism includes a screening box and a sliding screen box. The screening box is installed at the bottom of the mixing barrel, and the sliding screen box is slidably installed on the inner wall of the screening box. By opening the speed control valve of the mixing barrel, the mixed raw material enters the screening box and falls into the sliding screen box. The screening drive mechanism is opened to drive the sliding screen box to slide back and forth on the screening box, thereby screening the raw material through the sliding screen box.

[0010] Preferably, the screening drive mechanism includes a first turntable, a first eccentric shaft, a connecting rod, and a second motor. The first turntable is rotatably mounted on the inner wall of the screening box via a rotating shaft. The first eccentric shaft is eccentrically mounted on the first turntable.

The second motor is mounted on the outer wall of the screening box, and the output end of the second motor is connected to the first turntable. By opening the speed control valve of the mixing tank, the mixed raw material enters the screening box and falls into the sliding screen box. The second motor is turned on to drive the first turntable to rotate, which in turn drives the first eccentric shaft to rotate eccentrically. The connecting rod drives the sliding screen box to slide back and forth on the screening box, thereby screening the raw material through the sliding screen box.

[0011] Preferably, the striking mechanism includes a rotating seat, a rotating rod, a striking hammer, and a spring. The rotating seat is mounted on the outer wall of the feed hopper, the middle end of the rotating rod is rotatably mounted on the rotating seat, the striking hammer is mounted on one end of the rotating rod, one end of the spring is mounted on the outer wall of the feed hopper, and the other end of the spring is mounted on the rotating rod. By opening the striking drive mechanism, the rotating rod is driven to rotate on the rotating seat, and then the spring elasticity pulls the striking hammer to strike the outer wall of the feed hopper, thereby assisting the raw material to enter the extruder through the feed hopper.

The drive frame is mounted on the outer wall of the feed hopper, the second turntable is rotatably mounted on the drive frame, the second eccentric shaft is eccentrically mounted on the second turntable, and the third motor is mounted on the drive frame. The output end of the third motor is connected to the second turntable. By turning on the third motor, the second turntable is driven to rotate, which in turn drives the second eccentric shaft to rotate eccentrically. The second eccentric shaft then rotates the rotating rod on the rotating seat, causing the striking hammer to move away from the feed hopper. Subsequently, the elasticity of the spring pulls the striking hammer to strike the outer wall of the feed hopper, thereby assisting the raw material to enter the extruder through the feed hopper.
