Description

Technical Field

[0001] The utility model relates to the technical field of molecular sieve raw material crushing devices, in particular to a molecular sieve raw material crushing device. Background Art

[0002] Molecular sieve is a carbonaceous adsorbent in a broad sense, and in a narrow sense it is activated carbon with uniform micropore distribution. It is composed of crystalline carbon and amorphous carbon, has a highly developed pore structure and wedge-shaped micropores close to the diameter of the adsorbed molecules, and the pore size distribution is uniform, which can separate molecules with different sizes of three-dimensional structures. Since carbon molecular sieves have a strong affinity for molecules such as water and oil, the raw air must be very clean. However, due to the use of air compressors in pressure swing adsorption, water, oil vapor and other harmful chemical gases are inevitably brought into the air, resulting in blockage of the micropores of the nitrogen-making carbon molecular sieve and a gradual decrease in the separation effect. This is the so-called carbon molecular sieve poisoning. Molecular sieves are all microporous aluminosilicates with cubic lattices. The skeleton is composed of silicon tetroxide and aluminum tetroxide tetrahedrons. The physical properties of the hollows lead to damage and release of inorganic ions during use, so a cleaning device is needed to clean them.

[0003] The Chinese patent with the publication number CN212820399U discloses a pulverizing device for molecular sieve production, including a first pulverizing chamber, a second pulverizing chamber and a collection box, legs are fixed at both ends of the bottom of the first pulverizing chamber, a shaft is rotatably mounted on the output end of the first motor, pulverizing rods are fixed at both ends of the shaft, a second pulverizing chamber is fixed at the bottom of the first pulverizing chamber, and a first filter plate is fixed between the first pulverizing chamber and the second pulverizing chamber, a pulverizing disk is rotatably mounted on the output end of the second motor, a collection box is fixed at the bottom of the second pulverizing chamber, and a second filter plate is fixed between the collection box and the second pulverizing chamber, a drying mechanism is fixed on the other side of the first pulverizing chamber, and ventilation ports are provided on one side of the first pulverizing chamber and the second pulverizing chamber. The utility model is provided with a series of structures so that the device can effectively dry the raw materials for molecular sieve production during use, and improves the pulverizing effect of the raw materials for molecular sieve production.

[0004] However, the above patent has the following shortcomings: by setting a crushing rod, a crushing disk, a first filter plate and a second filter plate, the crushing rod performs preliminary crushing on the raw materials for producing molecular sieves, and the first filter plate can filter them, but during use, since the material particles on the first filter plate are still relatively large, the first filter plate will cause blockage during long-term use, so it is necessary to clean the first filter plate regularly to prevent it from being blocked.

When the rectangular tube 8 moves laterally, it drives the rectangular block 9 to move laterally. The brush installed at the bottom of the rectangular block 9 is used to sweep the top of the filter plate 4 back and forth to prevent the filter plate 4 from being blocked.

[0030] Furthermore, a plurality of springs 10 are vertically installed at the top of the rectangular tube 8, and the bottom of the spring 10 is connected to the top of the rectangular block 9;

[0031] Specifically,

[0033] Specifically, after the material is added into the feed barrel 6, the material presses the rectangular plate 12 downward under the action of gravity, and then the material is added into the crushing box 1.
