Description

Technical Field

[0001] The present application relates to the technical field of ceramic production, and more specifically, to a storage hopper with uniform material discharge and a ceramic press feeder. Background Art

[0002] In the prior art, the ceramic tile pressing process usually adopts a conical hopper, and a feeding hose is connected to the middle of the conical hopper, so that the powder can be discharged to the designated position along the feeding hose for distribution. The powder path of this process is: the powder enters the press storage tank from the silo, and then enters the press cavity through the conical hopper and the feeding hose for pressing.

[0003] In this process, since the diameter of the press storage tank is large and the diameter of the discharge hose is relatively small, the powder in the press storage tank will start to fall from the middle when discharging. According to the law of powder accumulation, coarse-grained powder will come out first, and fine-grained powder will gradually accumulate on the inner wall of the conical discharge hopper. In addition, due to the large specific surface area of ​​fine-grained powder, it is easy to agglomerate. When it agglomerates to a certain extent, it may suddenly collapse at a certain moment due to gravity and other factors, and then a large amount of fine-grained powder will flow into the press through the discharge hose, making it impossible to achieve uniform discharge from the discharge hopper. In this way, the press is prone to defects such as product interlayers and impurities during the pressing process of ceramic tiles, which affects the quality of ceramic products.

[0004] Therefore, the prior art needs to be improved. Utility Model Content

[0005] The purpose of the present application is to provide a storage hopper and a ceramic press feeder for achieving uniform material discharge, aiming to solve the technical problem of uneven material discharge from a conical lower hopper in the prior art.

[0006] To achieve the above purpose, the technical solution adopted in this application is:

[0007] In a first aspect, the present application provides a storage hopper for uniform material discharge, comprising:

[0008] A material storage portion, wherein the material storage portion has a first cavity with an inlet;

[0009] A duckbill hopper portion, one end of which is in communication with the first cavity;

[0010] A multi-channel discharge portion consisting of a plurality of outlets, wherein the multi-channel discharge portion is arranged on a side of the duckbill hopper portion away from the first cavity.

[0011] Through the above scheme, a multi-channel discharge part consisting of multiple outlets is provided in the duckbill hopper part. The multiple outlets cooperate with each other and influence each other during discharging, so that the multi-channel discharge part forms an unstable discharge environment, which can prevent fine-grained powder from gradually accumulating on the inner wall of the hopper, achieve uniform discharge of the storage hopper, and effectively prevent the powder from clogging the outlet.

[0012] In one embodiment, the duckbill hopper portion comprises:

[0013] Two length side walls, the length side walls are located in the length direction of the duckbill shaped hopper part, and the two length side walls are connected to the material storage part;

[0014] Two width side walls, the width side walls are located in the width direction of the duckbill-shaped hopper portion, and the two width side walls are connected to the material storage portion;

[0015] A hopper bottom plate, wherein the hopper bottom plate is connected to the two length side walls and the two width side walls, the hopper bottom plate, the width side walls and the length side walls are connected to form a duckbill cavity, the duckbill cavity is connected to the first cavity, and the multi-channel discharge part is arranged on the hopper bottom plate.

[0016] Through the above scheme, the duckbill hopper portion is composed of two length side walls, two width side walls and a hopper bottom plate to form a duckbill cavity, which has a simple structure and is easy to implement. It can prevent fine particle powder from gradually accumulating on the inner wall of the hopper and achieve uniform discharge of the storage hopper.

[0017] In one embodiment, the length side wall comprises:

[0018] Middle inclined plate;

[0019] Two curved surface connection plates, the two curved surface connection plates are respectively connected to the left and right sides of the middle inclined plate, and the middle inclined plate is connected to the width side wall through the curved surface connection plates.

[0020] Through the above scheme, the middle inclined plate is connected to the width side wall through the curved connecting plate, and the inclination angles of the middle inclined plate and the curved connecting plate are inconsistent, so that the powder is in an unstable state. If the inclination angle of the curved connecting plate is smaller, the curved connecting plate is relatively steeper, and the powder is not easy to accumulate during the powder discharge process. Therefore, the powder on one side of the curved connecting plate may drive the powder on the middle inclined plate, prompting the powder in the duckbill cavity to automatically dredge, realize uniform discharge of the storage hopper, and effectively avoid the powder blocking the outlet.

[0021] In one embodiment, the inclination angle of the middle inclined plate is 30°-50°.

[0022] Through the above scheme, the duckbill cavity has a cavity structure that is larger at the top and smaller at the bottom. The top of the middle inclined plate is connected to the material storage part, and the bottom of the middle inclined plate is connected to the hopper bottom plate. The inclination angle of the middle inclined plate helps the powder in the duckbill cavity to flow along the middle inclined plate to the outlet of the hopper bottom plate, avoiding the accumulation of powder in the duckbill cavity and effectively avoiding the powder from blocking the outlet.

[0023] In one embodiment, the inclination angle of the width sidewall is 2°-10°.

[0024] Through the above scheme, the inclination angle of the width side wall helps the powder in the duckbill cavity to flow along the width side wall to the outlet of the hopper bottom plate, avoiding the accumulation of powder in the duckbill cavity and effectively avoiding the clogging of the outlet by the powder. Compared with the middle inclined plate, the inclination angle of the width side wall is smaller, that is, the width side wall is relatively steeper. During the powder discharge process, the powder will not accumulate on the width side wall, and the powder on the width side wall will drive the powder on the curved connecting plate and the middle inclined plate to fall, thereby promoting the automatic dredging of the powder in the duckbill cavity.

[0025] In one embodiment, the multi-channel discharge section comprises:

[0026] A left side outlet, wherein the left side outlet is arranged on the left side of the hopper bottom plate of the duckbill shaped hopper part;

[0029] Through the above scheme, the left outlet, the middle outlet and the right outlet of the side can cooperate and influence each other when discharging materials, so that multiple outlets form an unstable discharging environment, so that the blocked powder is automatically unblocked, avoiding the accumulation of powder in the duckbill cavity, and effectively preventing the powder from blocking the outlet.

[0030] In one embodiment, the number of the middle outlets is set to two.

[0031] Through the above scheme, the two middle outlets can influence each other, causing multiple outlets to form an unstable discharging environment, so that the blocked powder is automatically unblocked, avoiding the accumulation of powder in the duckbill cavity, and effectively preventing the powder from blocking the outlet.

[0032] In one embodiment, the width of the hopper bottom plate is 120-180 mm;

[0033] The diameters of the left side outlet, the middle side outlet and the right side outlet are all consistent with the width of the hopper bottom plate.

[0034] Through the above scheme, the diameters of the left edge outlet, the middle edge outlet and the right edge outlet are all consistent with the width of the hopper bottom plate. The powder in the duckbill cavity can slide along the length side wall and the width side wall to the left edge outlet, the middle edge outlet and the right edge outlet, which can effectively prevent the powder from accumulating in the duckbill cavity.

[0035] In one embodiment, the material storage part comprises: a cylindrical structure, the diameter of the cylindrical structure is 1200-1500 mm;

[0036] The height of the duckbill hopper portion is 950-1250 mm.

[0037] Through the above scheme, the cylindrical structure can store a certain amount of powder to receive the powder transported by the conveyor belt, and the height of the duckbill hopper is 950-1250mm, so that the middle inclined plate is incline toward the middle at a certain angle, which can change the flow state of the powder and prevent the powder from being blocked at the outlet.

[0038] In a second aspect, the present application provides a ceramic press feeder, which includes:

[0039] A storage hopper for uniform discharge as described in the above embodiment;

[0040] A feed pipe, the feed pipe being connected to the duckbill hopper portion via the outlet;

[0041] A press distributor is connected to a side of the feed discharge pipe away from the duckbill hopper portion.

[0042] Through the above scheme, through the duckbill shape feature of the duckbill hopper part itself, and the multi-channel discharge part composed of multiple outlets at the bottom of the duckbill hopper part, the multiple outlets cooperate with each other and influence each other during discharging, so that the multi-channel discharge part forms an unstable discharge environment, which can prevent fine-grained powder from gradually accumulating on the inner wall of the hopper, realize uniform discharge of the storage hopper, and effectively prevent the powder from clogging the outlet.

[0056] Embodiment 1:

[0057] See also Figure 1 The present embodiment provides a storage hopper with uniform material discharge, which includes: a material storage portion 100, a duckbill hopper portion 200 and a multi-channel material discharge portion 300 composed of multiple outlets 310, the material storage portion 100 has a first cavity 110 with an inlet, one end of the duckbill hopper portion 200 is connected to the first cavity 110, and the multi-channel material discharge portion 300 is arranged on a side of the duckbill hopper portion 200 away from the first cavity 110.

[0058] In this embodiment, the storage hopper for uniform discharge includes a storage portion 100, a duckbill hopper portion 200 and a multi-channel discharge portion 300 composed of multiple outlets 310. The top of the duckbill hopper portion 200 is connected to the storage portion 100, and the bottom of the duckbill hopper portion 200 is connected to the multi-channel discharge portion 300. The duckbill hopper portion 200 changes the discharge flow channel to a certain extent, which helps to reduce the retention and blockage of powder, and can effectively prevent fine powder from accumulating on the inner wall of the hopper. The multi-channel discharge portion 300 is composed of multiple outlets 310, and the multiple outlets 310 can cooperate with each other and influence each other, so as to cause the multi-channel discharge portion 300 to form an unstable discharge environment, effectively preventing powder from clogging the outlets 310.

[0059] Therefore, in this embodiment, a multi-channel discharge portion 300 consisting of a plurality of outlets 310 is provided in the duckbill-shaped hopper portion 200. The plurality of outlets 310 cooperate with each other and influence each other during discharge, so that the multi-channel discharge portion 300 forms an unstable discharge environment, which can prevent fine-grained powder from gradually accumulating on the inner wall of the hopper, achieve uniform discharge from the storage hopper, and effectively prevent the powder from clogging the outlets 310.

[0060] For example, the storage hopper for uniform discharge includes a storage portion 100, a duckbill hopper portion 200, and a multi-channel discharge portion 300 composed of multiple outlets, wherein the storage portion 100 is used to receive the powder conveyed by the conveyor belt, and the powder enters the duckbill hopper portion 200 from the storage portion 100, and then the powder can be discharged from the duckbill hopper portion 200 through the multi-channel discharge portion 300. Figure 2 As shown in FIG. 1 , the outlet 310 of the conical hopper 200a is arranged at the center of the cone. During the accumulation process of the powder, the force is uniform, which makes it easy for the fine powder to be squeezed and accumulated on the inner wall of the hopper, and the fine powder is easy to agglomerate. The duckbill shape of the duckbill hopper part 200 itself causes the internal powder to be unevenly stressed, which is conducive to the discharge of the powder and effectively prevents the powder from blocking the outlet 310. In addition, the duckbill hopper part 200 is provided with a multi-channel discharge part 300 composed of a plurality of outlets 310. The plurality of outlets 310 are arranged in the discharge process. During the process, they can influence each other. For example, when two adjacent outlets 310 are discharging materials, if one of the outlets 310 is blocked or accumulated, the other outlet 310 can provide a certain amount of power to the adjacent outlet 310 during discharging materials, so as to automatically clear the blocked powder. In this way, the multiple outlets 310 can cooperate with each other and influence each other, so as to form an unstable discharging environment for the multi-channel discharging part 300, thereby preventing fine-grained powder from gradually accumulating on the inner wall of the hopper, achieving uniform discharging of the storage hopper, and effectively preventing the powder from clogging the outlet.

[0061] Specifically, see Figure 1The duckbill hopper portion 200 includes: two length side walls 210, two width side walls 220 and a hopper bottom plate 230. The length side walls 210 are located in the length direction of the duckbill hopper portion 200, and the two length side walls 210 are both connected to the material storage portion 100. The width side walls 220 are located in the width direction of the duckbill hopper portion 200, and the two width side walls 220 are both connected to the material storage portion 100. The hopper bottom plate 230 is connected to the two length side walls 210 and the two width side walls 220. The hopper bottom plate 230, the width side walls 220 and the length side walls 210 are connected to form a duckbill cavity 240. The duckbill cavity 240 is connected to the first cavity 110, and a multi-channel discharge portion 300 is arranged on the hopper bottom plate 230.

[0062] In the present embodiment, the duckbill hopper portion 200 is connected to the material storage portion 100, and the duckbill hopper portion 200 is composed of two length side walls 210, two width side walls 220 and a hopper bottom plate 230 to form a duckbill cavity 240. For example, the two length side walls 210 are respectively located at the front and rear sides of the duckbill hopper portion 200, the two width side walls 220 are respectively located at the left and right sides of the duckbill hopper portion 200, and the hopper bottom plate 230 is located at the bottom of the duckbill hopper portion 200. Its structure is simple and easy to implement.

[0063] Specifically, see Figure 1 and Figure 3 The length side wall 210 includes: a middle inclined plate 211 and two curved connecting plates 212 . The two curved connecting plates 212 are respectively connected to the left and right sides of the middle inclined plate 211 . The middle inclined plate 211 is connected to the width side wall 220 through the curved connecting plates 212 .

[0064] In the present embodiment, the middle inclined plate 211 is connected to the width side wall 220 through the curved connecting plate 212. It can be understood that the inclination angles of the middle inclined plate 211 and the curved connecting plate 212 are inconsistent. Therefore, if the powder is accumulated on the length side wall 210, the powder may be in an unstable state. For example, if the inclination angle of the curved connecting plate 212 is smaller, the curved connecting plate 212 is relatively steeper, and the powder is not easy to accumulate during the powder discharge process. Therefore, the powder on one side of the curved connecting plate 212 may drive the powder on the middle inclined plate 211, prompting the powder in the duckbill cavity 240 to automatically dredge, thereby achieving uniform discharge of the storage hopper and effectively avoiding the powder from clogging the outlet.

[0065] Optionally, the inclination angle θ2 of the middle inclined plate is 30°-50°.

[0066] For example, see Figure 4The inclination angle θ2 of the middle inclined plate is 30°-50°. It can be understood that the duckbill cavity 240 is a cavity structure that is larger at the top and smaller at the bottom. The top of the middle inclined plate 211 is connected to the material storage part 100, and the bottom of the middle inclined plate 211 is connected to the hopper bottom plate 230. The inclination angle θ2 of the middle inclined plate helps the powder in the duckbill cavity 240 to flow along the middle inclined plate 211 to the outlet 310 of the hopper bottom plate 230, thereby avoiding the accumulation of powder in the duckbill cavity 240 and effectively avoiding the powder from clogging the outlet 310.

[0067] Optionally, the inclination angle θ1 of the width sidewall is 2°-10°.

[0068] For example, see Figure 5 The inclination angle θ1 of the width side wall is 2°-10°, the top of the width side wall 220 is connected to the material storage part 100, and the bottom of the width side wall 220 is connected to the hopper bottom plate 230. The inclination angle θ1 of the width side wall helps the powder in the duckbill cavity 240 to flow along the width side wall 220 to the outlet of the hopper bottom plate 230, avoiding the accumulation of powder in the duckbill cavity 240, and effectively avoiding the clogging of the outlet by the powder. Compared with the middle inclined plate 211, the inclination angle θ1 of the width side wall is smaller, that is, the width side wall 220 is relatively steeper. During the powder discharge process, the powder is not easy to accumulate on the width side wall 220, and the powder on the width side wall 220 will drive the powder on the curved connecting plate 212 and the middle inclined plate 211, so as to promote the automatic dredging of the powder in the duckbill cavity 240.

[0069] In this embodiment, the inclination angle θ2 of the middle inclined plate is 30°-50°, and the inclination angle θ1 of the width side wall is 2°-10°, which can enable the powder to slide along the inner wall of the duckbill cavity 240 and prevent the powder from accumulating on the inner wall of the duckbill cavity 240, thereby ensuring uniform discharge from the storage hopper and avoiding collapse of the powder.

[0070] Specifically, see Figure 3 The multi-channel discharge portion 300 includes: a left side outlet 310a, a middle outlet 310b and a right side outlet 310c. The left side outlet 310a is arranged on the left side of the hopper bottom plate 230 of the duckbill hopper portion 200, the middle outlet 310b is arranged in the middle of the hopper bottom plate 230, and the right side outlet 310c is arranged on the right side of the hopper bottom plate 230.

[0071] In this embodiment, the left side outlet 310a, the middle side outlet 310b and the right side outlet 310c can cooperate with each other and influence each other during discharge, so that the multiple outlets form an unstable discharge environment, so that the blocked powder is automatically unblocked, and the powder is prevented from accumulating in the duckbill cavity 240, and the powder is effectively prevented from blocking the outlet. For example, the inclination angle θ1 of the width side wall is 2°-10°, and the inclination angle θ2 of the middle inclined plate is 30°-50°. If the middle outlet 310b accumulates and becomes blocked during discharge, the discharge of the left side outlet 310a and the right side outlet 310c will provide a certain amount of power to the middle outlet 310b, that is, the discharge of the powder on both sides will drive the powder at the position of the middle outlet 310b, so that the blocked powder is automatically unblocked, and the storage hopper is discharged evenly, and the powder is effectively prevented from blocking the outlet. For example, the left side outlet 310a, the middle side outlet 310b and the right side outlet 310c can be equidistantly arranged on the hopper bottom plate 230, that is, the spacing between two adjacent outlets 310 is the same, so as to achieve uniform discharge of the storage hopper. Preferably, the inclination angle θ1 of the width side wall is 2°, and the inclination angle θ2 of the middle inclined plate is 38°, so as to achieve uniform discharge of the storage hopper.

[0072] Optionally, the number of the middle outlets 310b is set to two.

[0073] For example, see Figure 3 , the number of the middle outlets 310b is set to two, and the two middle outlets 310b can affect each other, causing the multiple outlets to form an unstable discharge environment, so that the blocked powder is automatically unblocked, avoiding the accumulation of powder in the duckbill cavity 240, and effectively avoiding the powder blocking the outlet. Among them, the number of the middle outlets 310b can be determined according to the length of the hopper bottom plate 230, and the number of the middle outlets 310b can also be set to three or four. Therefore, in this embodiment, the number of the middle outlets 310b is not limited to the above two, and the number of the middle outlets 310b can also be other situations, which are not limited here.

[0074] Specifically, see Figure 3 The width of the hopper bottom plate 230 is 120-180 mm, and the diameters of the left side outlet 310 a, the middle side outlet 310 b, and the right side outlet 310 c are all consistent with the width of the hopper bottom plate 230 .

[0075] In this embodiment, the diameters of the left edge outlet 310a, the middle edge outlet 310b, and the right edge outlet 310c are all consistent with the width of the hopper bottom plate 230, and the powder in the duckbill cavity 240 can slide along the length side wall 210 and the width side wall 220 to the left edge outlet 310a, the middle edge outlet 310b, and the right edge outlet 310c, which can effectively prevent the powder from accumulating in the duckbill cavity 240. Among them, the left edge outlet 310a can be tangent to the left width side wall 220, and the right edge outlet 310c can be tangent to the right width side wall 220, which effectively prevents the powder from accumulating in the duckbill cavity 240, so as to achieve uniform discharge of the storage hopper and effectively prevent the powder from blocking the outlet.

[0076] Specifically, see Figure 1 and Figure 6 The material storage part 100 includes: a cylindrical structure 120, the diameter of the cylindrical structure 120 is 1200-1500mm; and the height of the duckbill hopper part 200 is 950-1250mm.

[0077] In this embodiment, the material storage section 100 includes a cylindrical structure 120, the diameter of the cylindrical structure 120 is 1200-1500mm, the height of the duckbill hopper section 200 is 950-1250mm, and the height of the cylindrical structure 120 can be 1000-1500mm. The cylindrical structure 120 can store a certain amount of powder to receive the powder transported by the conveyor belt, and the height of the duckbill hopper section 200 is 950-1250mm, so that the middle inclined plate 211 is inclination angle toward the middle, which can change the flow state of the powder and prevent the powder from being blocked at the outlet.

[0078] For example, the storage hopper for uniform discharge may include a storage portion 100, a duckbill hopper portion 200, and a multi-channel discharge portion 300 composed of multiple outlets, wherein the storage portion 100 includes a cylindrical structure 120, the diameter of the cylindrical structure 120 is 1350 mm, and the height of the cylindrical structure 120 can be 1300 mm, and the duckbill hopper portion 200 may include two length side walls 210, two width side walls 220, and a hopper bottom plate 230, and the length side wall 210 includes: a middle inclined plate 211, two curved surface connecting plates 212, and the middle inclined plate 211 is connected to the width side wall 220 through the curved surface connecting plate 212 to form a duckbill cavity 240, and the duckbill cavity 240 is close to One side of the material storage section 100 is matched and connected with the material storage section 100, the duckbill cavity 240 is circular near the side of the material storage section 100, the hopper bottom plate 230 can be rectangular, and the length side wall 210, the width side wall 220 and the hopper bottom plate 230 can be connected with an arc transition. Preferably, the inclination angle θ2 of the middle inclined plate can be 38°, the inclination angle θ1 of the width side wall can be 3°, the width of the hopper bottom plate 230 can be 120mm, and the multi-channel discharge section 300 can include a left edge outlet 310a, two middle outlets 310b and a right edge outlet 310c, and the diameters of the left edge outlet 310a, the two middle outlets 310b and the right edge outlet 310c are all 120mm. Among them, the duckbill hopper part 200 can be made of sheet metal, such as using several pieces of sheet metal for splicing, and then fixing them by welding to form the duckbill hopper part 200. The duckbill hopper part 200 can also be connected to the storage part 100 by welding. It can be seen that when the storage material is discharged from the hopper, the powder flows from the cylindrical first cavity 110 to the duckbill cavity. The duckbill hopper part 200 uses its own duckbill characteristics and the mutual influence and mutual promotion of multiple outlets 310 to avoid the accumulation of powder in the duckbill cavity 240, effectively avoid the powder blocking the outlet 310, and achieve uniform discharge of the storage hopper.

[0079] Embodiment 2:

[0080] See also Figure 6 Based on the storage hopper with uniform discharge in the above embodiment, the present embodiment provides a ceramic press feeder, which includes: a storage hopper with uniform discharge as in the above embodiment, a feed pipe 400 and a press feeder 500, the feed pipe 400 is connected to the duckbill hopper part 200 through the outlet, and the press feeder 500 is connected to the side of the feed pipe 400 away from the duckbill hopper part 200.

[0081] In this embodiment, a multi-channel discharge portion 300 composed of multiple outlets is provided at the bottom of the duckbill shaped hopper portion 200, and the multi-channel discharge portion 300 is connected to a press distributor 500 through a plurality of discharge pipes 400, so as to transport the powder in the storage hopper to the press distributor 500. The discharge pipes 400 and the press distributor 500 can be understood as prior art and will not be described in detail.

[0082] For example, the multi-channel discharge section 300 may include a left outlet 310a at the side, two middle outlets 310b and a right outlet 310c at the side, that is, the multi-channel discharge section 300 adopts four outlets 310, and the four outlets 310 can be connected to the press distributor 500 through four discharge pipes 400. The discharge pipe 400 can adopt a corrugated hose. The corrugated hose has good flexibility and scalability, and its structure is simple and easy to implement.

[0083] In this embodiment, the duckbill-shaped hopper part 200 has its own duckbill-shaped feature, and the multi-channel discharge part 300 is composed of multiple outlets 310 at the bottom of the duckbill-shaped hopper part 200. The multiple outlets 310 cooperate with each other and influence each other during discharge, so that the multi-channel discharge part 300 forms an unstable discharge environment, which can prevent fine-grained powder from gradually accumulating on the inner wall of the hopper, realize uniform discharge of the storage hopper, and effectively prevent the powder from blocking the outlet 310. For example, the powder can be transported to the storage hopper through a conveyor belt, and the powder first enters the storage part 100, and then enters the duckbill-shaped hopper part 200. After that, the duckbill-shaped hopper part 200 enters the multiple discharge pipes 400 from the multi-channel discharge part 300. The multiple discharge pipes 400 discharge at the same time, which can effectively prevent the powder from accumulating in the duckbill cavity 240, effectively prevent the powder from blocking the outlet 310, and prevent the ceramic product from having defects such as interlayers and impurities during the pressing process.

[0084] Therefore, the ceramic press feeder provided in this embodiment can solve the problem of powder blocking the outlet through the duckbill hopper part 200 combined with the multi-channel discharge part 300 composed of multiple outlets, so that the powder in the storage hopper is discharged evenly, which can improve the quality of the pressed products, reduce the production costs of the enterprise, and thus enhance the competitiveness of the enterprise's products.
