Description

Technical Field

[0001] The present application relates to the technical field of material processing, and in particular to a feeder. Background Art

[0002] A feeder is a device used for material conveying, mainly used for feeding, metering and mixing powder raw materials in the manufacturing process. Traditional feeders include worm feeders or gas conveying feeders, which are widely used in material conveying in various industries, such as food, chemicals, building materials, medicine, etc.

[0003] During the use of the feeder, material agglomeration and clogging is a problem that cannot be ignored. Therefore, how to avoid material clogging and agglomeration is a technical problem that needs to be solved today. Summary of the invention

[0004] The present application provides a feeder, which reduces the occurrence of material clogging and agglomeration.

[0005] In order to achieve the above objectives, the main technical solutions adopted in this application include:

[0006] In the first aspect, an embodiment of the present application provides a feeding machine, comprising a first feeding barrel and a stirring part, the first feeding barrel having a first accommodating chamber, and along the vertical direction, the upper end and the lower end of the first feeding barrel respectively having a first feed port and a first discharge port, and the first feed port and the first discharge port are both connected to the first accommodating chamber; the stirring part is arranged in the first accommodating chamber, and along the vertical direction, the stirring part is located between the first feed port and the first discharge port; wherein, the cross-sectional area of ​​the first accommodating chamber gradually decreases from the first feed port to the first discharge port; from the first feed port to the first discharge port, the inner side surface of the first feeding barrel comprises a plurality of buffer zones, two adjacent buffer zones comprise a first buffer zone and a second buffer zone, the first buffer zone is closer to the first feed port than the second buffer zone, and the roughness of the first buffer zone is greater than that of the second buffer zone.

[0007] The feeder proposed in the embodiment of the present application, the first accommodating chamber plays the role of accommodating materials, the first feed port is used for materials to enter the first accommodating chamber, the first discharge port is used for materials to leave the first accommodating chamber, and the stirring part can stir the materials in the first accommodating chamber, wherein the cross-sectional area of ​​the first accommodating chamber gradually decreases along the direction from the first feed port to the first discharge port, that is, the volume of the first accommodating chamber gradually decreases from the first feed port to the first discharge port, and the gradual reduction in cross-sectional area can form a guiding effect on the flow of materials, so that the materials can flow more smoothly from the feed port to the discharge port, which helps to reduce the retention and accumulation of materials in the first feeding barrel, improve the fluidity and uniformity of the materials, and reduce the probability of material agglomeration. In addition, the first buffer zone with a larger roughness can increase the friction between the materials and the inner wall of the first feeding barrel, which helps the flow of materials and avoids the accumulation or poor sliding of materials near the feed port; as the materials move toward the discharge port, the roughness gradually decreases, the material flow becomes smoother, and the possibility of material retention and blockage is reduced.

[0008] Optionally, along the vertical direction, the projection area of ​​the first feed port is S1, and the projection area of ​​the first discharge port is S2, satisfying 1 / 8≤S2 / S1≤1 / 3.

[0009] In the above scheme, the ratio of the projected areas of the first feed port and the first discharge port in the vertical direction satisfies the above range. The larger feed port area can ensure that the material enters the equipment smoothly, while the smaller discharge port area helps to control the outflow speed of the material and avoid material blockage and overflow. Therefore, on the one hand, it helps to reduce the probability of material agglomeration, and on the other hand, it can ensure the material transportation efficiency.

[0010] Optionally, 1 / 5≤S2 / S1≤1 / 4.

[0011] In the above scheme, the ratio of the projection area of ​​the first feed port to the first discharge port in the vertical direction satisfies the above range. On the one hand, the material conveying efficiency is further improved, and on the other hand, the probability of material agglomeration can be reduced.

[0012] Optionally, along the first direction, the cross-section of the first accommodating cavity includes a first straight edge and a second straight edge, and the distance between the first straight edge and the second straight edge gradually decreases from the first feed port to the first discharge port, and the first direction is orthogonal to the vertical direction.

[0013] In the above solution, the distance between the first straight edge and the second straight edge gradually decreases, that is, the first straight edge and the second straight edge are arranged in a cone shape, which can guide the material and reduce the probability of material agglomeration.

[0014] Optionally, an angle between the first straight line side or the second straight line side and the vertical direction is α, which satisfies: 20°≤α≤60°.

[0015] In the above scheme, the angle between the first straight edge or the second straight edge and the vertical direction satisfies the above range. On the one hand, it can ensure the material transportation efficiency, and on the other hand, it can guide the material and reduce the probability of material agglomeration.

[0016] Optionally, the first feeding barrel is further provided with a group of protrusions, which protrude from the inner side surface of the first feeding barrel.

[0017] In the above scheme, the group of protrusions arranged on the inner side of the first feeding barrel can hinder the material, reduce the speed of the material, effectively change the flow path of the material, help reduce the blockage and accumulation of the material during the flow process, and thus reduce the chance of material agglomeration.

[0018] Optionally, there are multiple protrusion groups, and the multiple protrusion groups are arranged at intervals in the direction from the first feed port to the first discharge port.

[0019] In the above scheme, multiple groups of protrusions are spaced apart between the first feed port and the first discharge port. The spaced-apart groups of protrusions can effectively change the flow path of the material, making it more uniform and stable, and help reduce blockage and accumulation of the material during the flow process, thereby reducing the chance of material agglomeration.

[0020] Optionally, each protrusion group includes one or more protrusions, and two adjacent protrusion groups include a first protrusion group and a second protrusion group. The first protrusion group is closer to the first feed port than the second protrusion group, and the protrusion height of any protrusion in the first protrusion group is greater than the protrusion height of any protrusion in the second protrusion group.

[0021] In the above scheme, the height difference of the raised parts can form a gradient for material flow, which helps the material to be more evenly distributed and flow in the first feeding barrel. At the same time, it can serve as a guide for material flow, reducing the risk of material retention and blockage in the first feeding barrel.

[0022] Optionally, each protrusion group includes one or more protrusions, and the protrusions are configured as protrusion ribs, and the protrusion ribs extend along the circumference of the first charging barrel.

[0023] In the above scheme, the raised ribs can change the flow path of the material in the first feeding barrel, making it more uniform and stable, and can also play a guiding role, guiding the material to flow in a predetermined direction, reducing the possibility of material retention and blockage.

[0024] Optionally, the feeder further comprises a second feeding barrel, which is vertically connected to the lower end of the first feeding barrel, a second accommodating chamber is provided inside the second feeding barrel, and a part of the stirring part is arranged in the second accommodating chamber.

[0025] In the above scheme, the first accommodating chamber is connected to the second accommodating chamber, so that the material flows out of the first accommodating chamber and enters the second accommodating chamber, and a part of the stirring part is arranged in the second accommodating chamber, so that the material entering the second accommodating chamber will continue to be stirred, thereby achieving continuous stirring of the material and reducing the possibility of material retention and blockage.

[0044] As an example, the feeder includes a worm feeder and a gas conveying feeder. A worm feeder is a feeder based on spiral motion, consisting of a worm and a pipe, wherein the worm is a spiral-shaped device and the pipe is a channel for conveying materials to the destination.

[0045] In the food industry, worm feeders can be used to convey powdered, granular and bulk materials, such as flour, beans, candy, etc. In the chemical industry, worm feeders can be used to convey chemical raw materials and powder particles. In the building materials industry, worm feeders can be used to convey cement, lime, fly ash and other materials. In the pharmaceutical industry, worm feeders can be used to convey pharmaceutical raw materials and powder particles.

[0046] A gas conveying feeder is a feeder that uses the energy of airflow to transport granular materials along the direction of airflow in a closed pipe based on the principle of pneumatic conveying. Gas conveying feeders can also be divided into suction type, pressure type and mixed type according to the speed and pressure of the airflow.

[0047] As an example, the powder material includes, but is not limited to, fine powder or ultrafine powder of metals, alloys, ceramics, composites, and similar materials with controllable properties, which is not limited in the present application.

[0048] As an example, metal powder refers to a group of metal particles with a size less than 1 mm, including single metal powder, alloy powder and certain refractory compound powders with metallic properties, which are the main raw materials for powder metallurgy.

[0049] As an example, alloy powder is a metal powder formed by partial or complete alloying of two or more components. Common alloy powders include iron alloy powder, copper alloy powder, nickel alloy powder, cobalt alloy powder, aluminum alloy powder, titanium alloy powder and precious metal alloy powder.

[0050] As an example, ceramic powder refers to a powdered substance obtained by fully mixing and sintering all raw materials when preparing ceramics. The main components of ceramic powder include but are not limited to silicon oxide, aluminum oxide, zirconium oxide, silicon carbide, and silicon nitride.

[0051] As an example, synthetic powder refers to a fine granular substance composed of synthetic resin and various additives, including but not limited to plastic powder composed of synthetic resin and additives such as fillers, plasticizers, stabilizers, lubricants, colorants, etc. Plastic powder is a synthetic polymer compound.

[0052] As an example, fine powder refers to powder composed of particles with a particle size of 10μm-44μm, and ultrafine powder refers to powder with a particle size less than 10μm. Ultrafine powder can be further classified according to particle size. Specifically, ultrafine powder can be divided into micron-level (1μm-10μm), submicron-level (0.1μm-1μm) and nano-level (1nm-100nm) powders.

[0053] The fine conveying and uniform feeding of powder materials have always been a difficult problem in the industry, especially for certain metal powders. When the size is small enough to approach the nanoscale, the surface energy increases sharply and agglomeration occurs easily. General feeders, such as traditional worm feeders or gas conveying feeders, are difficult to convey or feed powders with poor fluidity. Blockage, agglomeration, heating and other phenomena often occur during the conveying process.

[0054] In view of this, in order to reduce the probability of material agglomeration, the present application embodiment provides a feeder, such as Figure 1 As shown, it includes a first feeding bucket 1 and a stirring part 2,

[0055] The first feeding barrel 1 has a first accommodating chamber 10. It can be understood that the first accommodating chamber 10 contains materials in the feeding process. In the vertical direction, the upper and lower ends of the first feeding barrel 1 respectively have a first feed port 101 and a first discharge port 102, and the first feed port 101 and the first discharge port 102 are both connected to the first accommodating chamber 10.

[0056] It can be understood that the first feed port 101 serves to allow materials to flow in, and the first discharge port 102 serves to allow materials to flow out. Materials flow into the first accommodating chamber 10 through the first feed port 101 and flow out of the first accommodating chamber 10 through the first discharge port 102 .

[0057] Since the first feed port 101 and the first discharge port 102 are arranged in the vertical direction, the material can flow in the first accommodating chamber 10 under the action of gravity, which helps to reduce the possibility of material accumulation or blockage in the barrel and improves the smoothness of material flow.

[0058] The stirring part 2 is disposed inside the first accommodating chamber 10 and is arranged vertically between the first feed port 101 and the first discharge port 102. That is, after the material enters the first accommodating chamber 10 from the first feed port 101, it reaches the stirring part 2, and the stirring part 2 plays a role in stirring the material, and then the stirred material flows out through the first discharge port 102.

[0059] It can be understood that the stirring part 2 stirs the material, which can cause the material to form a circulating flow in the first containing chamber 10, thereby improving the fluidity of the material, helping to reduce the residence time of the material in the first feeding barrel 1, and thus reducing the possibility of the material agglomerating in the first containing chamber 10.

[0060] In the direction from the first feed port 101 to the first discharge port 102 , the cross-sectional area of ​​the first accommodating cavity 10 gradually decreases.

[0061] It can be understood that as the cross-sectional area of ​​the first accommodating chamber 10 gradually decreases, the material is subjected to gradually increasing pressure during the flow from the first feed port 101 to the first discharge port 102, thereby accelerating the flow of the material and ensuring that the material flows smoothly in the first feeding barrel 1, avoiding material accumulation or blockage in the barrel.

[0062] Along the direction from the first feed port 101 to the first discharge port 102, the inner side surface of the first feeding barrel 1 includes a plurality of buffer zones 4, adjacent buffer zones 4 include a first buffer zone 41 and a second buffer zone 42, the first buffer zone 41 is closer to the first feed port 101 than the second buffer zone 42, and the roughness of the first buffer zone 41 is greater than the roughness of the second buffer zone 42.

[0063] In the above scheme, the area close to the first feed port 101 has a greater roughness, and the rough surface can more effectively grasp and guide the material into the first feeding barrel 1, thereby reducing the material flow rate, helping to prevent the material from accumulating in the first feeding barrel 1, and ensuring that the material can flow smoothly to the first discharge port 102, thereby reducing the chance of material agglomeration.

[0064] It can be understood that the roughness of the second buffer zone 42 is smaller than that of the first buffer zone 41 , which can reduce the probability of material agglomeration and blockage while increasing the flow rate of the material, thereby ensuring the feeding efficiency.

[0065] In some other embodiments, along the vertical direction, the projection area of ​​the first feed port 101 is S1, and the projection area of ​​the first discharge port 102 is S2, satisfying: 1 / 8≤S1 / S2≤1 / 3.

[0066] In the above scheme, since the ratio of the projection area of ​​the first feed port 101 in the vertical direction to the projection area of ​​the first discharge port 102 in the vertical direction satisfies the above range, on the one hand, it can ensure that the material flows into and out of the first accommodating chamber 10 quickly and smoothly, thereby improving the efficiency of feeding. On the other hand, it can reduce the probability of material agglomeration and blockage, thereby ensuring the stability and uniformity of material flow.

[0067] It can be understood that the area of ​​the feed port is relatively large, which facilitates the material to enter the first feeding barrel 1 quickly and smoothly, while the area of ​​the discharge port is relatively small, which can control the outflow speed of the material to a certain extent and help maintain the stability of the material flow.

[0068] In addition, the moderate area of ​​the feed port can ensure that the material does not cause excessive blockage or accumulation when it is added to the first feeding barrel 1, thereby improving the efficiency of feeding. The corresponding design of the discharge port area can ensure the smooth outflow of materials while preventing the materials from flowing out too quickly and causing the production rhythm to be out of control.

[0069] In some other embodiments, the following condition is satisfied: 1 / 5≤S1 / S2≤1 / 4.

[0070] In the above scheme, since the projection area of ​​the first feed port 101 in the vertical direction and the projection area of ​​the first discharge port 102 in the vertical direction meet the above range, on the one hand, the feeding efficiency can be further improved, and on the other hand, the probability of material agglomeration can be further reduced.

[0071] In other embodiments, along the first direction, the cross-sectional area of ​​the first accommodating cavity 10 includes a first straight edge 11 and a second straight edge 12, and the distance between the first straight edge 11 and the second straight edge 12 gradually decreases from the first feed port 101 to the first discharge port 102, and the first direction is orthogonal to the vertical direction.

[0072] In the above scheme, the distance between the first straight edge 11 and the second straight edge 12 gradually decreases along the direction from the first feed port 101 to the first discharge port 102, that is, the first straight edge 11 and the second straight edge 12 form a cone, which plays a role in optimizing the material flow path. When the material flows to the inner wall of the first accommodating chamber 10 due to gravity, the material is subjected to extrusion pressure and guiding effects in different directions under the action of the first straight edge 11 or the second straight edge 12, thereby promoting the dispersion of the materials and reducing the probability of material agglomeration and blockage.

[0073] In other embodiments, Figure 2 As shown, the included angle between the first straight edge 11 or the second straight edge 12 and the vertical direction is α, which satisfies: 20°≤α≤60°.

[0074] In the above scheme, since the angle between the first straight edge 11 or the second straight edge 12 and the vertical direction satisfies the above range, on the one hand, the movement path of the material can be optimized, the dispersion between the materials can be promoted, and the probability of material agglomeration and blockage can be reduced. On the other hand, it can ensure that the flow rate of the material is not greatly affected, thereby ensuring the feeding efficiency.

[0075] It can be understood that the angle between the first straight edge 11 or the second straight edge 12 and the vertical direction helps to adjust the flow direction and speed of the material in the first accommodating chamber 10, which can ensure that the material maintains a stable flow state during the flow process and avoids accumulation or blockage of the material in the barrel.

[0076] Moreover, the angle between the first straight edge 11 or the second straight edge 12 and the vertical direction can guide the material. When the material flows in the first accommodating chamber 10, it can be subjected to extrusion and guidance in different directions, which is helpful for dispersing the material, thereby reducing the probability of material agglomeration and blockage.

[0077] Optionally, α can be 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, or 60°.

[0078] In other embodiments, Figure 3 As shown, the first feeding bucket 1 is further provided with a protrusion group 3 , and the protrusion group 3 is located on the inner side of the first feeding bucket 1 .

[0079] In the above solution, the protrusion group 3 can change the flow path and speed of the material in the first accommodating chamber 10 , guide the material to flow more smoothly, and reduce the accumulation and blockage of the material in the first accommodating chamber 10 .

[0080] It can be understood that when the material flows in the first accommodating chamber 10, the protrusion group 3 will continuously contact and collide with the material, thereby promoting the dispersion of the material and reducing the probability of material agglomeration.

[0081] In some other embodiments, the protrusion group 3 is provided in plurality, and the plurality of protrusion groups 3 are arranged at intervals in a direction from the first feed port 101 to the first discharge port 102 .

[0082] In the above solution, the plurality of protrusion groups 3 are arranged at intervals between the first feed port 101 and the first discharge port 102. The plurality of protrusion groups 3 can change the material flow path, so that the material is subjected to more disturbance and shear force during the flow process, which helps the material to be more evenly distributed in the first accommodating chamber 10, reducing the risk of material accumulation and blockage. In addition, the intervals between the protrusion groups 3 can ensure that the material has enough space to disperse during the flow process, thereby improving the uniformity of the material.

[0083] It can be understood that the material will collide and rub against the multiple protrusion groups 3 during the flow process, further improving the dispersion effect of the material. The provision of multiple protrusion groups 3 can further increase the probability of collision with the material, thereby improving the efficiency of material dispersion.

[0084] In other embodiments, each protrusion group 3 includes one or more protrusions 30 .

[0085] In the above scheme, multiple protrusions 30 can provide more collision and friction points during the flow of materials, which is helpful for the dispersion of materials and can significantly improve the uniformity of materials. The protrusions 30 can also change the flow path of materials, so that the materials are more disturbed during the flow process, which helps to reduce the accumulation and blockage of materials in the barrel and improve the fluidity of materials.

[0086] In other embodiments, two adjacent protrusion groups 3 include a first protrusion group 31 and a second protrusion group 32, the first protrusion group 31 is closer to the first feed port 101 than the second protrusion group 32, and the protrusion height of any protrusion 30 in the first protrusion group 31 is greater than the protrusion height of any protrusion 30 in the second protrusion group 32.

[0087] In the above scheme, the protruding height of any protrusion 30 in the first protrusion group 31 is greater than the protruding height of any protrusion 30 in the second protrusion group 32. That is to say, after the material enters the first accommodating chamber 10 through the first feed port 101, it will first contact the first protrusion group 31 with a larger protruding height. The first protrusion group 31 can effectively change the flow direction of the material and make the material more evenly distributed in the barrel.

[0088] As the material flows toward the first discharge port 102 , the second protrusion group 32 contacts the material and plays a further dispersing role, thereby ensuring that the material can be fully dispersed in the entire first feeding barrel 1 .

[0089] It can be understood that the higher protrusion 30 in the first protrusion group 31 can provide a larger collision area and a stronger shear force, which is conducive to the full dispersion of the material. As the material flows toward the second protrusion group 32, although the protruding height of the protrusion 30 decreases, it can still play a role in guiding and dispersing the material, and can prevent the material from being excessively guided and affecting each other to produce agglomeration; so that a gradually weakening mixing area is formed in the entire first accommodating cavity 10, ensuring the flow stability and dispersion uniformity of the material, and reducing the probability of material accumulation and blockage.

[0090] In other embodiments, each protrusion group 3 includes one or more protrusions 30 , and the protrusions 30 are configured as protrusion ribs 301 . The protrusion ribs 301 extend along the circumference of the first charging barrel 1 .

[0091] In the above solution, the raised ribs 301 can change the flow path of the material in the first feeding barrel 1 and make the material subject to more disturbance and shear force during the flow. This helps to distribute the material more evenly in the barrel and reduce the risk of accumulation and blockage. At the same time, the raised ribs 301 can also guide the flow of the material to ensure that the material can flow smoothly to the discharge port.

[0092] It is understandable that the material will collide and rub against the raised ribs 301 during the flow process, which helps to disperse the material. The design of the raised ribs 301 extending along the circumferential direction can further increase the contact area and collision frequency with the material, thereby improving the dispersion effect and further reducing the probability of material agglomeration.

[0093] In other embodiments, a first feeding barrel 1 and a stirring part 2 are included. A first accommodating chamber 10 is provided inside the first feeding barrel 1, and along the vertical direction, two ends of the first accommodating chamber 10 are respectively connected with a first feed port 101 and a first discharge port 102, and the stirring part 2 is located between the first feed port 101 and the first discharge port 102, and the cross-sectional area of ​​the first accommodating chamber 10 gradually decreases along the direction from the first feed port 101 to the first discharge port 102, and along the vertical direction, the projection area of ​​the first feed port 101 is S1, and the projection area of ​​the first discharge port 102 is S2, which satisfies 1 / 8≤S1 / S2≤1 / 3, preferably 1 / 5≤S1 / S2≤1 / 4.

[0094] Along the first direction, the cross-section of the first accommodating cavity 10 includes a first straight edge 11 and a second straight edge 12. In the direction from the first feed port 101 to the first discharge port 102, the distance between the first straight edge 11 and the second straight edge 12 has gradually decreased. The first direction intersects with the vertical direction, and the angle between the first straight edge 11 or the second straight edge 12 and the vertical direction is α, satisfying: 20°≤α≤60°.

[0095] The inner side of the first feeding barrel 1 is also provided with a protrusion group 3, which includes a plurality of protrusion groups 3 arranged at intervals in the direction from the first feed port 101 to the first discharge port 102. Each protrusion group 3 includes one or more protrusions 30, and two adjacent protrusion groups 3 include a first protrusion group 31 and a second protrusion group 32. The first protrusion group 31 is closer to the first feed port 101 than the second protrusion group 32, and the protrusion height of any protrusion 30 in the first protrusion group 31 is greater than the protrusion height of any protrusion 30 in the second protrusion group 32.

[0096] The protrusion 30 is configured as a protrusion rib 301 , and the protrusion rib 301 extends along the circumference of the first charging bucket 1 .

[0097] From the first feed port 101 to the first discharge port 102, the inner side of the first feed barrel 1 includes a plurality of buffer zones 4, two adjacent buffer zones 4 include a first buffer zone 41 and a second buffer zone 42, the first buffer zone 41 is closer to the first feed port 101 than the second buffer zone 42, and the roughness of the first buffer zone 41 is greater than the roughness of the second buffer zone 42. The feeder of this solution reduces the probability of material agglomeration and blockage, and improves the smoothness and uniformity of material flow.

[0098] In other embodiments, the feeding machine also includes a second feeding barrel. In the vertical direction, the second feeding barrel 13 is connected to the lower end of the first feeding barrel 1.
