Description

Technical Field

[0001] The utility model belongs to the technical field of feeders and relates to a disc feeder, in particular to a disc feeder suitable for powder collection. Background Art

[0002] Disc feeder is a commonly used material conveying equipment. It can convey materials from the storage bin to the next equipment. The feeding amount can be adjusted to play a buffering emergency role. It can not only ensure the normal operation of each process, but also save labor, protect equipment performance, and extend the service life of the entire production line equipment. Generally speaking, the materials conveyed by the disc feeder are powdery, granular or small block materials, among which the production process of pellets mainly includes the grinding and granulation of raw materials. At the same time, during the transportation and transfer of the produced pellets, the pellets are prone to collision, causing the powder on the surface of the pellets to fall off, thereby affecting the product quality of the balls and increasing the subsequent workload. Therefore, before the material is fed to the next equipment, it is necessary to effectively remove the powder in the material.

[0003] The existing disc feeder can realize the transportation of materials, but it cannot remove the powder in the material during operation, which is not conducive to the smooth progress of the subsequent process, and it cannot control the feeding amount of raw materials in different forms other than powder, and has poor adaptability. In addition, the existing disc feeder only seals the raw materials through the discharge valve. Due to the imperfect sealing, it cannot be applied to raw materials in different forms. In particular, when the raw materials in different forms are discharged to the receiving disk and the scraper is used for discharge, it is inevitable that the raw materials are easily worn repeatedly on the receiving disk, and are in contact with the outside air for a long time, which is easy to produce more powder, and is easy to deteriorate and oxidize. At the same time, due to the poor sealing effect of the raw materials or the lack of a sealing mechanism, it is easy to cause the raw materials (especially powdered materials) to generate dust during the discharge process, and these dusts are scattered in the air, which is also easy to cause air pollution, which is not conducive to improving the working environment of workers and will also affect the actual production efficiency.

[0004] Therefore, it is necessary to propose a disc feeder which is suitable for powder collection, has good sealing effect and is environmentally friendly. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a disc feeder which is suitable for powder collection and has good sealing effect in view of the deficiencies in the prior art.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions.

[0010] As a further improvement of the above technical solution: the first row of hoppers is in the shape of a truncated cone.

[0011] As a further improvement of the above technical solution: the second row of hoppers is in the shape of an inverted frustum of a cone.

[0012] As a further improvement of the above technical solution: the dust removal mechanism includes a fan, the air inlet of the fan is connected to the dust removal cavity through a dust removal pipe; the fan is connected to a dust collection bag; and the fan is also provided with an exhaust port.

[0013] As a further improvement of the above technical solution: a discharge amount regulating mechanism is also provided in the sealed cavity; the discharge amount regulating mechanism comprises an electric telescopic rod, a disc is provided on the horizontal plane of the telescopic end of the electric telescopic rod, and a discharge cone is detachably mounted on the disc; the shape and size of the discharge cone are adapted to the inner wall of the discharge pipe.

[0014] As a further improvement of the above technical solution: the disc feeder also includes a driving mechanism, which includes a motor and a rotating shaft. The output end of the motor is connected to an electric telescopic rod through the rotating shaft, and is used to drive the electric telescopic rod to perform up and down telescopic movement and to drive the disc to perform rotational movement; the driving mechanism is arranged in the sealed cavity; the motor is detachably installed in the second row hopper through a plurality of support rods.

[0015] As a further improvement of the above technical solution: a discharge valve is provided at the bottom of the sealed cavity; the discharge valve is connected to the sealed cavity through a discharge pipe.

[0016] Compared with the prior art, the advantages of the utility model are:

[0017] (1) In view of the defects of the existing devices such as poor sealing effect, easy generation of dust and difficulty in removing powder from the material, the utility model creatively proposes a disc feeder suitable for powder collection, including a sealing cavity connected to the discharge port of the storage bin, and a dust removal mechanism is connected to the sealing cavity. On the one hand, by setting up the sealing cavity, the sealing effect of the disc feeder can be effectively improved, thereby reducing the contact between the raw materials and the air during the discharge process, thereby effectively avoiding the deterioration and oxidation of the material. On the other hand, by setting up the sealing cavity, the dust generated during the discharge process can be reduced from entering the outside. In the external environment, the risk of environmental pollution can be effectively reduced. More importantly, under the promotion of the sealed cavity, the advantage of the low air leakage rate of the sealed cavity can be utilized to significantly improve the dust collection effect of the dust removal mechanism, so that the powder generated in the material can be effectively removed, and the adverse effects of the powder on the subsequent process can be effectively avoided. In particular, the disc feeder of the utility model can also effectively remove the powder attached to the surface of the pellets when used to transport lithium mineral pellets (such as lithium mica pellets).

[0027] The present invention is further described below in conjunction with the accompanying drawings and specific preferred embodiments, but the protection scope of the present invention is not limited thereby.

[0028] The materials and instruments used in the following examples are all commercially available.

[0029] Example

[0030] like Figure 1 As shown, the disc feeder suitable for powder collection in this embodiment includes a sealed cavity connected to the discharge port of the storage bin 1, and a dust removal mechanism is connected to the sealed cavity.

[0031] In this embodiment, the sealed cavity is composed of a first row hopper 3 and a second row hopper 4. Specifically, the first row hopper 3 is in the shape of a truncated cone, and the second row hopper 4 is in the shape of an inverted truncated cone. The sealed cavity can be formed by combining the first row hopper 3 and the second row hopper 4 together, wherein the discharge port of the storage bin 1 is connected to the feed port of the first row hopper 3 through the discharge pipe 2. In this embodiment, the storage bin 1 is in an inverted cone, wherein the inclination angle of the conical surface at the bottom of the storage bin 1 is 45°, that is, the angle between the conical surface and the horizontal plane is 45°, so as to ensure that the material (irregular ball material) rolls down effectively and enters the sealed cavity through the discharge pipe 2.

[0032] like Figure 2As shown, in this embodiment, the first discharge hopper 3 is in the shape of a frustum, and its diameter gradually increases from top to bottom. Such a setting can promote the effective regulation of the discharge amount control mechanism on the raw materials, which is beneficial to controlling the discharge rate and improving production efficiency; in particular, the first discharge hopper 3 is composed of an outer wall and an inner wall, and a dust removal cavity is formed between the outer wall and the inner wall; a plurality of dust removal holes 13 are opened on the inner wall, specifically, the dust removal holes 13 are arranged in a row and evenly distributed on the inner wall, which is beneficial to improving the dust removal effect, and in addition, the dust removal holes 13 are adjusted according to actual production needs; the dust removal cavity is connected with the sealing cavity through the dust removal hole 13; the dust removal cavity is connected with the dust removal mechanism through the dust removal pipe 14.

[0033] like Figure 3 As shown, in this embodiment, the second discharge hopper 4 is in the shape of an inverted frustum of a cone, and its diameter gradually decreases from top to bottom, which is conducive to collecting raw materials and improving discharge efficiency.

[0034] like Figure 2 As shown, in this embodiment, the dust removal mechanism includes a fan 15, and a dust collection bag 17 is connected to the fan 15 and is located on the side of the fan 15; the fan 15 is also provided with an exhaust port 16, which is located at the bottom of the fan 15. In this embodiment, the air inlet of the fan 15 is connected to the dust removal cavity through the dust removal pipe 14, and then the fan 15 can be used to absorb the powder in the raw material and transfer and store it in the dust collection bag 17, which is conducive to realizing the resource utilization of the powder and reducing the production cost. Furthermore, by adjusting the power of the fan 15, the powder adsorbed on the surface of the pellets can be effectively removed, thereby effectively removing the powder attached to the surface of the pellets, and significantly reducing the adverse effects of the powder on the subsequent roasting equipment.

[0035] like Figure 3 and Figure 4As shown, in this embodiment, a discharge amount control mechanism is also provided in the sealed cavity, and the discharge amount control mechanism includes an electric telescopic rod 10, and a disc 11 is provided on the horizontal plane of the telescopic end of the electric telescopic rod 10, and a discharge cone 12 is detachably mounted on the disc 11; the shape and size of the discharge cone 12 are adapted to the inner wall of the discharge pipe 2. In this embodiment, when discharging, the downward movement of the electric telescopic rod 10 makes the discharge cone 12 away from the discharge pipe 2, and the material falls from the storage bin 1. During the discharge process, the discharge rate can be effectively controlled by the discharge amount control mechanism, which is also conducive to improving the dust collection effect of the dust removal mechanism. In particular, by using a discharge cone that is adapted to the specifications (shape and size) of the discharge pipe for control, on the one hand, the conical surface of the discharge cone 12 can prevent the material from accumulating on the top surface of the disc 11, which is conducive to improving the discharge effect. On the other hand, through the dispersion effect of the discharge cone 12, the dust collection effect of the dust removal mechanism can also be promoted, so that the powder in the material can be removed more efficiently and thoroughly. After the discharge is completed, the electric telescopic rod 10 moves upward, so that the discharge cone 12 is close to the discharge pipe 2 and closes with the discharge pipe 2. At this time, the material stops falling from the storage bin 1.

[0036] like Figure 3 and Figure 4 As shown, in this embodiment, the disc feeder also includes a driving mechanism, which includes a motor 8 and a rotating shaft 9. The output end of the motor 8 is connected to the electric telescopic rod 10 through the rotating shaft 9, and is used to drive the electric telescopic rod 10 to perform up and down telescopic movements, and can also drive the disc 11 to perform rotational movements. On the one hand, the disc can be driven to rotate by the drive of the motor 8, thereby preventing the raw materials from being blocked between the disc 11 and the inner wall of the first discharge hopper 3 during the discharge process. On the other hand, the discharge cone 12 can be driven up and down by the drive of the motor 8, which is conducive to realizing the regulation of the discharge rate.

[0037] In this embodiment, the driving mechanism is arranged in the sealed cavity, specifically, the motor 8 is detachably installed in the second row hopper 4 through a plurality of (e.g., 6) support rods 7. In this embodiment, the motor 8 is fixed in the second row hopper 4 through the fixing effect of the support rods 7, which can reduce the volume of the disc feeder and simplify the structure.

[0038] like Figure 1 and Figure 5As shown, in this embodiment, a discharge valve 6 is provided at the bottom of the sealed cavity, wherein the discharge valve 6 is connected to the sealed cavity through a discharge pipe 5. When discharging, the discharge valve 6 is closed synchronously, thereby sealing the sealed cavity, which can reduce the contact between the raw material and the air during the dust removal process, has good sealing, low air leakage rate, and significantly improved dust collection effect. Furthermore, when the storage volume in the second discharge hopper 4 reaches a preset value, the discharge valve 6 is opened, thereby the discharge pipe 5 can be used to discharge the dust-removed raw materials to the next device. During the discharge process, the opening and closing degree of the discharge valve 6 can be adjusted according to actual conditions to achieve the best dust removal effect.

[0039] The working principle and use process of the utility model are as follows: when the device is required to work, the motor 8 is first turned on, and the rotating shaft 9 is used to drive the electric telescopic rod 10 to move downward, driving the disc 11 to descend to a suitable position, and the discharge valve 6 is opened at the same time, and the rotating shaft 9 is driven by the motor 8 to rotate, and the electric telescopic rod 10 and the disc 11 are driven to rotate (rotate) to prevent the raw material from being blocked between the disc 11 and the first hopper 3. The raw material enters the discharge pipe 5 through the discharge pipe 2, the first discharge hopper 3 and the second discharge hopper 4 in turn. In this process, the fan 15 is turned on, the dust removal mechanism is started, and the raw material is dusted. Finally, the raw material is discharged through the feed pipe 5 and the discharge valve 6. During the entire discharge process, the raw material has less contact with the air and good sealing. At the same time, the dust generated by the discharge enters the dust removal pipe 14 through the dust removal hole 13, and finally enters the dust collection bag 17 driven by the fan 15.

[0040] Compared with conventional disc feeders, the disc feeder of the utility model includes a sealed cavity connected to the discharge port of the storage bin, and a dust removal mechanism is connected to the sealed cavity. On the one hand, by setting the sealed cavity, the sealing effect of the disc feeder can be effectively improved, thereby reducing the contact between the raw materials and the air during the discharge process, thereby effectively avoiding the deterioration and oxidation of the materials. On the other hand, by setting the sealed cavity, the dust generated during the discharge process can be reduced from entering the external environment, thereby effectively reducing the risk of environmental pollution. More importantly, under the promotion of the sealed cavity, the advantage of the low air leakage rate of the sealed cavity can be utilized to significantly improve the dust collection effect of the dust removal mechanism, thereby effectively removing the powder generated in the material, and then effectively avoiding the adverse effects of the powder on the subsequent process. In particular, the disc feeder of the utility model can also effectively remove the powder attached to the surface of the pellets when used to transport lithium mineral pellets (such as lithium mica pellets). By reducing the powder attached to the surface of the pellets, the adverse effects of the powder on the subsequent roasting equipment can be significantly reduced. The utility model disc feeder has the advantages of simple structure, convenient operation, good sealing effect, good dust removal effect, etc. It is a new type of feeder and can be widely used for conveying various industrial materials (especially lithium mineral pellets). It has high use value and good application prospect.
