Description

Technical Field

[0001] The utility model relates to the technical field of air flow pulverizers, in particular to an air flow pulverizer for molecular sieve fine powder. Background Art

[0002] Molecular sieve is a kind of aluminosilicate compound with cubic lattice. Molecular sieve has uniform microporous structure and its pore diameter is uniform. These pores can adsorb molecules smaller than their diameter into the inside of the pore cavity, and have preferential adsorption capacity for polar molecules and unsaturated molecules, so it can separate molecules with different polarity, saturation, molecular size and boiling point, that is, it has the function of "screening" molecules, so it is called molecular sieve. Molecular sieve has the advantages of high adsorption capacity and strong thermal stability that other adsorbents do not have, so it is widely used.

[0003] The air flow mill currently in use has too much concentrated materials when feeding into the machine, and because the wind direction is consistent, the direction of material movement is also consistent, and then the frequency of material collision is reduced, which affects the efficiency of fine powder screening.

It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0023] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0024] A molecular sieve fine powder airflow pulverizer provided by some embodiments of the utility model is described below in conjunction with the accompanying drawings.

[0025] Embodiment 1:

[0026] Combination Figure 1-3 As shown, the utility model provides a molecular sieve fine powder airflow mill, comprising a counter module 100 and a crushing module 200, wherein the counter module 100 comprises an airflow milling device 110, two material distribution channels 120 connected and communicated with the airflow milling device 110, a main flow channel 130 connected between the two material distribution channels 120, a partition 140 installed inside the main flow channel 130, a high-pressure fan 150 connected and communicated with the main flow channel 130, and a shunt pipe 160 connected between the airflow milling device 110 and the main flow channel 130, wherein the shunt pipe 160 is arranged at the bottom of the main flow channel 130;

[0027] The crushing module 200 includes a plurality of legs 210 connected to the main channel 130, a silo 220 connected between the plurality of legs 210, a grid plate 230 installed at the bottom of the silo 220, a cover body 240 sleeved on the top of the silo 220, a hydraulic cylinder 250 connected to the cover body 240, and a pressure plate 260 arranged inside the silo 220 and connected to the movable end of the hydraulic cylinder 250, and the bottom end of the silo 220 is connected to the inside of the main channel 130.

[0028] Furthermore, the two material distribution channels 120 are vertically symmetrical with respect to the airflow pulverizing device 110 . The material of the material distribution channels 120 is the same as that of the main flow channel 130 . This layout design is adopted to increase the probability of collision between raw materials.

[0029] Furthermore, the partition 140 is configured in a triangular shape and is located between the two material distribution channels 120. This shape design can distinguish the directions of the raw materials and wind in the mainstream channel 130, thereby providing conditions for the opposite outflow of the raw materials.

[0030] Furthermore, a plurality of legs 210 are arranged in a matrix, and the bottom of the legs 210 is located at the same horizontal plane as the bottom of the airflow pulverizing device 110 . This layout design can improve the installation firmness of the silo 220 .

[0031] Embodiment 2:

[0032] Combination Figure 1-3 As shown, based on the first embodiment, the pressing plate 260 is configured as an isosceles trapezoid, and the pressing plate 260 and the grid plate 230 are both made of metal materials. This shape design can prevent the raw materials from staying on the pressing plate 260.

[0033] Embodiment three:

[0034] Combination Figure 1-3 As shown, in the above embodiment, a covered feed channel is installed on the cover body 240 , and the covered feed channel is located on one side of the hydraulic cylinder 250 . The covered feed channel is provided to facilitate the staff to replenish raw materials into the silo 220 .

[0035] Working principle and use process of the utility model: When the device is put into actual use, raw materials are put into the silo 220 through the covered feed channel, and then the hydraulic cylinder 250 brings the pressing plate 260 to rise and fall, and the pressing plate 260 crushes the raw materials into the mainstream channel 130. During this process, the grid plate 230 changes the raw materials to be smaller, so that the raw materials can move flexibly in the mainstream channel 130, and then the high-pressure fan 150 is started. Then, under the separation of the partition 140, the raw materials are divided into two streams, and then flow out from two oppositely arranged diverter pipes 160, which increases the collision frequency and makes the raw materials easier to be finely powdered, and then the upward wind blown out by the diverter pipe 160 is discharged from the air flow crushing device 110, which effectively improves the fine powder screening efficiency.

[0036] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
