The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.

As described in the background of the present application, as shown in FIG. 1, since the gap between the top plate 1011 and the bottom surface 1012 of the fluidization groove 101 forms a passage for gas to flow, during the process of fluidizing the material by introducing compressed gas, the gas flow carries the material to wash out in the gap formed by the top plate 1011 and the bottom surface 1012, which easily causes the abrasion of the bottom plate 1012 to cause material leakage.

Based on this, the embodiment of the present application provides a fluidizing device 20, which is used for solving the technical problem that the material leakage is caused by the abrasion of the bottom surface of the fluidizing tank due to the fact that the material carried by the airflow is washed in the gap formed by the top plate and the bottom surface of the fluidizing tank. As shown in fig. 2, the fluidizing device 20 includes a fluidizing tank 201 and a gas feeding pipe 202, wherein the fluidizing tank 201 includes a bottom 2011 and at least one side 2012, the bottom 2011 and the at least one side 2012 form a uncovered box, the bottom 2011 has a first opening 20111, the gas feeding pipe 202 communicates with the fluidizing tank 201 through the first opening 20111, and one end a of the gas feeding pipe 202 extends into the fluidizing tank 201.

The fluidization groove 201 includes a bottom 2011 and at least one side 2012, and specifically may include a bottom 2011 and a side 2012, and in this case, the shape of the uncovered box may include, but is not limited to, an uncovered cylinder and an uncovered circular truncated cone. When the uncovered box body is in the shape of an uncovered cylinder, the bottom 2011 is the bottom of the cylinder, and the side 2012 is the side of the cylinder; when the uncovered box body is in the shape of a uncovered circular truncated cone, the bottom 2011 is the bottom of the circular truncated cone, and the side 2012 is the side of the circular truncated cone. The fluidization tank 201 may also include a bottom 2011 and a plurality of sides 2012, for example, four sides, and the uncovered box may be a rectangular box. It should be understood that the above description is only an example of the shape of the fluidization groove 201, and the specific shape of the fluidization groove 201 is not particularly limited in the embodiments of the present application. As shown in fig. 3, the fluidization groove 201 may further include a discharge port 2 and a compressed gas inlet 1, and when the gas is introduced into the fluidization groove 201 through the gas supply pipe 202 to fluidize the material, the compressed gas may be introduced through the compressed gas inlet 1, and the discharge port 2 is opened, so that the material flows out of the fluidization groove 201 through the discharge port 2. In practical applications, the other end (B) of the gas supply pipe 202 exposed out of the fluidization groove 201 and the compressed gas inlet 1 may be connected to the same compressed gas conveying pipe or different compressed gas conveying pipes, and when the other end is connected to different compressed gas conveying pipes, the gas at different pressures may be provided, which is not specifically limited in the embodiment of the present application.

The gas feed conduit 202 is sealingly connected to the rim of the first opening 20111 to prevent leakage of material.

It can be understood that, in the fluidizing device 20 provided in the embodiment of the present application, by extending the end a of the gas supply pipe 202 into the fluidizing tank 201, the gas can directly enter the fluidizing tank 201 through the gas supply pipe 202 to disturb the material, and no longer form a channel for gas circulation based on the gap between the top plate 1011 and the bottom surface 1012 of the fluidizing tank 101 in fig. 1, so as to reduce the erosion of the bottom surface of the fluidizing tank, and further reduce the wear of the bottom surface of the fluidizing tank.

The compressed gas can directly enter the fluidization groove 201 through the end a of the air supply pipe 202 extending into the fluidization groove 201, and in practical applications, in order to further enhance the disturbance degree of the air flow entering the fluidization groove 201 through the air supply pipe 202 to the materials in the fluidization groove 201, a mode of forming holes can be adopted.

For example, in one embodiment, the fluidizing device 20 further comprises a blocking device 203, as shown in fig. 4, the end a of the gas supply pipe 202 extending into the fluidizing tank 201 is connected with the blocking device 203, and the blocking device 203 has a second opening 2031.

The number of the second holes 2031 may be multiple, and multiple second holes 2031 may be uniformly arranged on the plugging device 203 in a circular or annular shape, so as to further optimize the fluidization effect on the material.

It can be understood that, by the above scheme, the second opening 2031 is arranged on the plugging device 203, and the compressed gas can enter the fluidization groove 201 through the second opening 2031, so that the pressure of the gas flow entering the fluidization groove 201 is enhanced, the disturbance degree of the gas flow to the material in the fluidization groove 201 is enhanced, and the fluidization of the material is further realized more quickly; on the other hand, the material can be prevented from flowing backwards into the air feeding pipeline 202.

For example, in another embodiment, the fluidizing device 201 further comprises a blocking device 203, as shown in fig. 5, the end a of the gas feeding pipe 202 extending into the fluidizing tank 201 is connected with the blocking device 203, and the end a of the gas feeding pipe 202 extending into the fluidizing tank 201 is provided with a third opening 2021.

The number of the third openings 2021 may be multiple, and the multiple third openings 2021 may be arranged around the pipe wall at equal intervals on the end a of the air duct 202 extending into the fluidization groove 201, so as to further optimize the fluidization effect on the material.

It can be understood that, with the above solution, the third opening 2021 is provided at the end a of the air duct 202 extending into the fluidization groove 201, and the compressed gas can enter the fluidization groove 201 through the third opening 2021, so that the pressure of the air flow entering the fluidization groove 201 is increased, thereby increasing the disturbance degree of the air flow to the material in the fluidization groove 201, and further achieving the fluidization of the material more quickly; on the other hand, the material can be prevented from flowing backwards into the air feeding pipeline 202.

For example, in another embodiment, the fluidizing device 20 further comprises a blocking device 203, as shown in fig. 6, the end a of the gas supply pipe 202 extending into the fluidizing tank 201 is connected with the blocking device 203, the blocking device 203 has a second opening 2031, and the end a of the gas supply pipe 202 extending into the fluidizing tank 201 is provided with a third opening 2021.

The number of the second openings 2031 may be multiple, and the number of the third openings 2021 may also be multiple. The second openings 2031 may be arranged uniformly in a circle or ring shape on the plugging device 203 to further optimize the fluidization of the material. A plurality of third openings 2021 may be arranged around the pipe wall at equal distances at the end a of the air duct 202 extending into the fluidizing tank 201 to further optimize the fluidizing effect on the material.

It can be understood that, by the above solution, the second opening 2031 is provided on the blocking device 203, and the third opening 2021 is provided at the end a of the air duct 202 extending into the fluidization groove 201, so that the compressed air can enter the fluidization groove 201 through the second opening 2031 and the third opening 2021, so that the pressure of the air flow entering the fluidization groove 201 is increased, thereby increasing the disturbance degree of the air flow to the material in the fluidization groove 201, and further achieving the fluidization of the material more quickly; on the other hand, the material can be prevented from flowing backwards into the air feeding pipeline 202. And, set up the trompil on plugging device 203 and the said one end A that the air feed pipe 202 stretches into in the said fluidization groove 201 at the same time, make can further improve the disturbance degree of the air current to the supplies in the fluidization groove 201, thus further realize the fluidization of the supplies faster.

In practical applications, in order to further reduce the erosion on the bottom surface of the fluidization groove and thus reduce the wear on the bottom surface of the fluidization groove, in one embodiment, the second opening 2031 provided on the blocking device 203 and the third opening 2021 provided on the end a of the air supply pipe 202 extending into the fluidization groove 201 are spaced from the bottom surface 2011 of the fluidization groove 201 by a distance greater than or equal to a predetermined value.

The preset value is larger than zero, and experiments show that when the preset value is 5cm, the fluidization effect on the material is good. In practical applications, the preset value may also be set according to actual requirements, for example, the preset value may be set according to the height of the fluidization tank 201, and for example, the preset value is one tenth of the height of the fluidization tank 201. Assuming that the height of the fluidization groove 201 is 50cm, the distances between the second opening 2031 and the third opening 2021 and the bottom 2011 of the fluidization groove 201 are in the range of 5cm to 50 cm.

It can be understood that, by the above solution, the distances between the second opening 2031 and the third opening 2021 and the bottom 2011 of the fluidization groove 201 are greater than or equal to the predetermined value, and the distances between the second opening 2031 and the third opening 2021 and the bottom 2011 of the fluidization groove 201 are further increased, so that the erosion of the airflow to the bottom of the fluidization groove is further reduced, and the wear of the bottom of the fluidization groove is further reduced.

In order to avoid that the material below the positions of the second opening 2031 and the third opening 2021 in the fluidization groove 201 is difficult to be disturbed, it is more preferable that the second opening 2031 provided on the blocking device 203 and the third opening 2021 provided on the end a of the air duct 202 extending into the fluidization groove 201 are spaced from the bottom 2011 of the fluidization groove 201 by a distance greater than or equal to a predetermined value, and spaced from the bottom 2011 of the fluidization groove 201 by a distance less than or equal to a target predetermined value.

The target preset value can be set according to actual requirements. For example, the target preset value may be set according to the height of the fluidization tank 201, such as the target preset value is one fifth of the height of the fluidization tank 201. Assuming that the height of the fluidization groove 201 is 50cm, in combination with the above-mentioned embodiments, the distance between the second opening 2031 and the third opening 2021 and the bottom 2011 of the fluidization groove 201 ranges from 5cm to 10 cm.

With the long-term operation of the fluidizing device 20, the holes (such as the second opening 2031 and the third opening 2021) are flushed by the airflow for a long time, which may cause the holes to be deformed or blocked, and further affect the fluidizing effect of the material. Therefore, in the case that the fluidizing device 20 further includes a blocking device 203, the end a of the gas supply pipe 202 extending into the fluidizing tank 201 is connected to the blocking device 203, and the blocking device 203 has a second opening 2031, it is more preferable that the blocking device 203 is a hood, and as shown in fig. 7, the end a of the gas supply pipe 202 extending into the fluidizing tank 201 is detachably connected to the hood.

It can be understood that, through the above scheme, the plugging device 203 is the hood, the air supply pipeline 202 stretches into one end a in the fluidization groove 201 with the hood can be dismantled and be connected for when the hole warp or block up and influence the material fluidization effect, can be convenient for replace with new hood, thereby guarantee the fluidization effect of material.
