[0002] The existing equipment for producing granular materials will actually cause material agglomeration when producing materials, and the transportation of granular materials often uses air conveying. The agglomerated materials will affect the subsequent air conveying of the materials. For example, fluorine-loaded alumina materials contain a large number of agglomerates with a particle size greater than 2 mm after production. These agglomerates accumulate on the boiling canvas of the air conveying chute, resulting in poor boiling effect of the entire air conveying chute, thereby affecting the fluidity of the fluorine-loaded alumina, and ultimately resulting in the inability to transport the fluorine-loaded alumina normally. Regular slag cleaning and blockage removal are required, and the difficulty and frequency of slag cleaning and blockage removal are high, affecting the material conveying efficiency.

[0003] Therefore, people are in urgent need of a granular material sand removal device with good sand removal effect and high material conveying efficiency. Summary of the Invention

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] The purpose of the utility model is to provide a device for removing sand from particulate materials to solve the problems existing in the prior art. By utilizing an inclined fluidized bed, agglomerated materials can also flow on the fluidized bed without causing blockage of the fluidized bed, thereby ensuring the normal transportation of materials. The desanding net can screen the materials and improve the desanding effect.

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0027] Please refer to Figure 1As shown, a particulate material sand removal device is provided, comprising a box body 2, a sand removal net 8, a fluidized bed 3 and a discharge chamber 7. The mesh diameter of the sand removal net 8 is smaller than the agglomerated particle size. The fluidized bed 3 divides the box body 2 into an upper material flow space and a lower space. The discharge port of the box body 2 is connected to the discharge chamber 7 through the sand removal net 8. The fluidized bed 3 is tilted in the box body 2. The end of the fluidized bed 3 close to the sand removal net 8 is lower than the end away from the sand removal net 8. The lower space between the fluidized bed 3 and the bottom wall of the box body 2 is an air chamber 4 for providing boiling power. The air flow in the air chamber 4 passes through the fluidized bed 3 and enters the material flow space to blow the non-agglomerated material to boil and flow. The sand removal net 8 is located on the path of the material boiling movement; the fluidized bed 3 is tilted The arrangement makes it possible for the agglomerated material to flow on the fluidized bed 3 under the combined action of gravity and the air driving force of the air chamber 4. The flow rate is slower than that of the unagglomerated material. The flowing agglomerated material gathers at the lower end and will not block the fluidized bed 3 on a large scale. This can ensure the boiling fluidity and flow stability of the material in the box body 2, and the normal use time of the device. The sand removal net 8 intercepts the agglomerated material, thereby improving the sand removal effect, so that the material after sand removal has high purity and fluidity, thereby improving the flow stability during subsequent gas transportation, and effectively reducing the difficulty and frequency of slag removal and blockage removal during subsequent gas transportation, greatly reducing labor and improving material transportation efficiency.

[0028] Preferably, the discharge port of the box body 2 is a hole opened on the box body 2 , and the sand removal net 8 is arranged at the hole so that the agglomerated materials intercepted by the net fall directly onto the lower end of the fluidized bed 3 .

[0029] The bottom end of the discharge port of the box body 2 is set to be higher than the end of the boiling bed 3 close to the discharge side of the box body 2. The inner wall of the box body 2 between the discharge port of the box body 2 and the lower end of the boiling bed 3 will serve as a blocking component to prevent the continued movement of the agglomerated material. The box body 2 is provided with a sand discharge channel 6. The inlet end of the sand discharge channel 6 is flush with the top surface of the end of the boiling bed 3 close to the discharge side of the box body 2. The sand discharge channel 6 is provided with a first valve. The end of the sand discharge channel 6 away from the boiling bed 3 can be set vertically downward or inclined downward; when the agglomerated material needs to be discharged, the first valve is opened, and the agglomerated material will be discharged from the sand discharge channel 6, thereby improving the discharge efficiency of the agglomerated material gathered in the box body 2.

[0030] When the first valve is opened, the material conveyance should be stopped to prevent the unagglomerated material from being discharged from the sand discharge channel 6 .

[0031] In order to improve the degree of automation of the device and reduce the intensity of manual labor, the first valve is set to be a solenoid valve.

[0032] Since there will be agglomerated materials in the width direction of the lower end of the boiling bed 3, the inlet end length of the sand discharge channel 6 is set to be the same as the width of the boiling bed 3, that is, the inlet end of the sand discharge channel 6 is used as an extension of the boiling length, and the width of the two parts is the same.

[0033] Since the agglomerated materials will collide with the box body 2 between the sand removal net 8 and the inlet end of the sand discharge channel 6, in order to improve the service life of the box body 2, a steel plate is provided on the inner wall of the box body 2 between the sand removal net 8 and the inlet end of the sand discharge channel 6, or the box body 2 between the sand removal net 8 and the inlet end of the sand discharge channel 6 is made of steel, that is, this part of the box body exists as a steel plate.

[0034] The air inlet 5 of the air chamber 4 is arranged close to the sand removal net 8, so that the material close to the sand removal net 8 can be fully boiled, and it is convenient to pass through the sand removal net 8 into the discharge chamber 7, thereby reducing the content of conventional particle size materials in the agglomerated materials and improving the sand removal effect.

[0035] In order to facilitate the collection of materials after sand removal, a second valve is provided at the bottom discharge port 10 of the discharge chamber 7, and a breathable cap 9 is provided on the top of the box body 2. The breathable cap 9 can be used for gas discharge, but it is provided with a corresponding filter to block the discharge of materials; the second valve is opened when the material in the discharge chamber 7 needs to be discharged, and the discharge chamber 7 is not opened during the process of collecting materials.

[0036] Preferably, the second valve is a solenoid valve, which improves the degree of automation of the device and reduces manual labor intensity.

[0037] The feed port 1 of the box body 2 is arranged at the top of the box body 2 , and the feed port 1 is arranged corresponding to the end of the boiling bed 3 away from the sand removal net 8 .

[0038] A conical section is provided at the bottom of the discharge chamber 7, the small diameter end of the conical section is connected to the discharge port 10, and the diameter of the small diameter end of the conical section is the same as the diameter of the discharge port 10, to avoid material residue in the discharge chamber 7 when the material is discharged.

[0039] During actual installation, the feed port 1 of the box body 2 can be directly connected to the discharge end of the silo.

[0040] During actual use, the material enters the box body 2 from the feed port 1 of the box body 2, and is affected by the airflow blowing from the bottom to the top of the boiling bed 3. The unagglomerated material boils and flows to the desanding net 8. The agglomerated material flows along the boiling bed 3 and gathers. The unagglomerated material after being desanded by the desanding net 8 enters the discharge chamber 7 and is collected, and the agglomerated material gathers in the sand discharge channel 6 and waits for regular discharge.

[0041] Adaptive changes based on actual needs are all within the protection scope of this utility model.
