[0002] Moisturizing soil is a non-metallic mineral with montmorillonite as the main mineral component. The montmorillonite structure is a 2:1 type crystal structure composed of two silicon-oxygen tetrahedrons sandwiching a layer of aluminum-oxygen octahedrons. Due to the layered structure formed by the montmorillonite unit cell, there are certain cations, such as Cu, Mg, Na, K, etc., and these cations are very unstable in the interaction with the montmorillonite unit cell and are easily exchanged by other cations, so it has good ion exchangeability. It has been used in more than 100 departments in 24 fields of industrial and agricultural production abroad, with more than 300 products, so people call it "universal soil";

[0003] Before the storage process of bentonite, the bentonite may be damp due to the environment.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 4, an anti-clogging ventilating device for a bentonite storage tank, comprising a shell 1, a plurality of electric heating rods 11 are fixedly connected to the inner bottom of the shell 1, a sealing cover 7 is installed at the upper end of the shell 1, and a support frame 2 is installed at the lower end of the shell 1;

[0022] The ventilation mechanism includes a fan 5 installed on the left side of the housing 1. The fan 5 is a fan 5 with an electromagnetic valve inside. When it is not in use, the internal channel is in a cut-off state and has good sealing performance. The air outlet of the fan 5 extends to the inside of the housing 1. The right side space of the housing 1 is connected to the outside through a folded exhaust pipe 6. The motor 8 is a servo motor that can change the rotation direction.

[0023] The stirring mechanism includes a motor 8 mounted at the lower end of the housing 1, the output shaft of the motor 8 extends into the housing 1 and is fixedly connected to a rotating shaft 9, and a plurality of rotating rods 10 are fixedly connected to the outer side of the rotating shaft 9 at equal intervals;

[0024] Among them, a hollow box 3 is fixedly connected to the left side of the shell 1, an activated carbon plate 4 is installed on the inner bottom of the hollow box 3, the air inlet end of the fan 5 extends to the top space of the hollow box 3, a filter 13 is arranged in the exhaust duct 6, a sealing plate 12 is arranged at the upper end of the exhaust duct 6, a rectangular frame 16 is fixedly connected to the inner side of the exhaust duct 6, a plurality of connecting rods 14 are fixedly connected to the upper end of the filter 13, the plurality of connecting rods 14 all pass through the rectangular frame 16, and are fixedly connected to the lower end of the sealing plate 12, and the upper end of the rectangular frame 16 is elastically connected to the lower end of the sealing plate 12 by a spring 15.

[0025] In the utility model, when in use, bentonite is filled in the shell 1. By using the support frame 2, the shell 1 can be prevented from directly contacting the ground, thereby improving moisture resistance. During storage, the electric heating rod 11 and the motor 8 can be started regularly. After the motor 8 is started, the rotating shaft 9 will be driven to rotate. The rotation of the rotating shaft 9 will drive the multiple rotating rods 10 to rotate, turning the bentonite, so that the bentonite is fully in contact with the electric heating rod 11, and is fully dried to analyze the water adsorbed in the bentonite. After a period of time, the motor 8 and the electric heating rod 11 are turned off. 1, and start the fan 5. After the fan 5 is started, the outside air will be dried by the activated carbon plate 4 and discharged into the shell 1, and finally discharged from the exhaust pipe 6. The airflow enters the shell 1 and discharges the humid air inside the shell 1 through the exhaust pipe 6. When the airflow is discharged, the sealing plate 12 moves up and the end of the exhaust pipe 6 is opened. The spring 15 is in a stretched state. At the same time, the connecting rod 14 is used to move the filter 13 up. The use of the filter 13 can prevent the bentonite raised in the shell 1 from being directly discharged to the outside with the airflow.

[0026] After the fan 5 is turned off, the airflow disappears, the sealing plate 12 moves downward under the elastic action of the spring 15, and finally collides with the exhaust pipe 6 and stops moving, thus achieving sealing, and the filter screen 13 will eventually recover. Figure 4 The dust under the filter 13 falls down by inertia. In addition, the impact vibration generated by the sealing plate 12 and the exhaust pipe 6 will be transmitted to the filter 12, so that the dust under it will be separated. The fallen dust will eventually fall into the shell 1. This method can achieve a certain anti-blocking effect and facilitate the next use.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
