Description

Technical Field

[0001] The utility model relates to the technical field of material distributors, in particular to a material distributor and a material distribution system. Background Art

[0002] When producing catalysts used in the petrochemical industry, a distributor is used to distribute the formed catalyst to the dryer for drying. The ideal distribution effect should ensure that the catalyst material is evenly distributed along the dryer body in terms of particle size, chemical composition, moisture, etc., ensuring that the catalyst material has uniform air permeability, while ensuring that the material surface is flat and has a certain degree of looseness to prevent accumulation or compression.

[0003] Generally, the catalyst is mainly distributed on the drying belt on the dryer frame. Since the width of the discharge port of the forming machine does not match the width of the feed port of the dryer, when the catalyst is distributed on the drying belt, the catalyst often gathers in the center of the drying belt of the dryer, which is not conducive to the drying of the catalyst.

[0004] To this end, existing technologies further install specialized distributors at the width of the molding machine's discharge port and the dryer's feed port to spread the catalyst onto the drying belt. For example, the distribution device and material conveying system disclosed in CN220906570U includes a distribution plate and a connecting rod assembly. The connecting rod assembly is configured to reciprocate the distribution plate along its length through the forward and reverse rotation of a drive shaft. However, this distribution device still has several drawbacks: the connecting rod assembly is an offset crank slider mechanism, and due to its quick return characteristics, it cannot ensure uniform distribution of the catalyst during the distribution plate's reciprocating motion. Different dryer models have different drying belt widths, and the drying belt width determines the distribution plate's travel. Adjusting the distribution plate's travel requires redesigning the connecting rod mechanism's arm length and offset distance, which is very inconvenient. The distribution plate cannot ensure the catalyst is loose and breathable during distribution. Utility Model Content

[0005] The utility model mainly solves the technical problem that the existing distributor is difficult to be applied to drying belts of different widths.

[0006] In order to achieve the above-mentioned object, the first aspect of the present invention provides a distributor, comprising:

[0007] a driving member having an output end;

[0008] a distribution plate, the distribution plate being used to be arranged above the drying belt;

[0009] a transmission assembly, the transmission assembly comprising a turntable and a connecting rod assembly eccentrically disposed on the turntable, the turntable being connected to the output end, and the connecting rod assembly being connected to the distribution plate;

[0010] Wherein, the transmission assembly is configured to be able to drive the cloth plate to reciprocate along the length direction of the cloth plate through the forward and reverse rotation of the driving member, and the connecting rod assembly is detachably connected to the turntable.

[0011] In some embodiments, the transmission assembly further includes a slider and a guide rod, wherein the slider is detachably arranged on the surface of the turntable, the guide rod is integrally arranged with the connecting rod assembly, and a guide groove is provided in the guide rod along the length direction to accommodate the slider sliding in the guide rod.

[0012] In some embodiments, the length of the guide groove is greater than or equal to the diameter of the turntable.

[0013] In some embodiments, the connecting rod assembly includes a first connecting rod and a second connecting rod, the first connecting rod and the second connecting rod are respectively arranged on both sides of the guide rod, and the distribution plate is arranged at the lower end of the guide rod.

[0014] In some embodiments, the turntable is a ring, and the driving member is coaxially arranged with the turntable.

[0015] In some embodiments, the end surface of the distribution plate is provided with a comb tooth structure.

[0016] In some embodiments, a guide assembly is further included, and the connecting rod assembly moves along the length direction of the cloth plate under the action of the guide assembly.

[0017] In some embodiments, a limiting component is further included, and the limiting component is used to limit the movement range of the cloth plate.

[0018] In some embodiments, the limiting assembly includes two limiting blocks for being arranged on the dryer, and the two limiting blocks are respectively arranged on the outer sides of the ends of the distribution plate.

[0019] A second aspect of the present invention provides a material distribution system, comprising:

[0020] A molding machine, wherein a silo is provided at the bottom of the discharge port of the molding machine;

[0021] The dryer comprises a rotating drying belt, wherein the feed end of the drying belt is located below the discharge end of the silo;

[0022] The distributor is used to spread the materials that fall onto the drying belt.

[0023] Through the above technical solution, the transmission assembly of the distributor includes a turntable and an eccentrically arranged connecting rod assembly. Since the connecting rod assembly is connected to the distribution plate, the rotation of the turntable can be converted into reciprocating motion of the connecting rod assembly along the length of the distribution plate. This structure is a sinusoidal mechanism, and the stroke of the reciprocating motion is twice the distance from the center of the turntable to the connection point between the connecting rod assembly and the turntable. Because the connecting rod assembly and the turntable are detachably connected, when the distributor is installed on different dryers, the stroke of the reciprocating motion of the distribution plate can be changed by simply adjusting the connection point of the connecting rod assembly on the turntable. In addition, the transmission assembly of this solution has no quick return characteristics, which can ensure that the catalyst is evenly spread when the distribution plate reciprocates.

[0035] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0036] In order to solve the problem in the prior art that the existing distributor is difficult to adapt to drying belts of different widths, the first aspect of the present invention provides a distributor, comprising: a driving member 6, the driving member 6 having an output end;

[0037] A cloth plate 7 is provided above the drying belt 1;

[0038] The transmission assembly 3 includes a turntable 31 and a connecting rod assembly 34 eccentrically arranged on the turntable 31, the turntable 31 is connected to the output end, and the connecting rod assembly 34 is connected to the distribution plate 7;

[0039] The transmission assembly 3 is configured to drive the cloth plate 7 to reciprocate along the length direction of the cloth plate 7 through the forward and reverse rotation of the driving member 6, and the connecting rod assembly 34 is detachably connected to the turntable 31.

[0040] like Figure 1-3 As shown, the drive member 6 can be a motor, with its output end being the motor's output shaft. The distribution plate 7 can be a long, strip-shaped structure extending along the width of the drying belt 1. The length of the distribution plate 7 can be smaller than the width of the drying belt 1 to prevent the material from being spread out of the drying belt 1 during reciprocating motion. The distribution plate 7 is configured to maintain a preset distance from the drying belt 1 based on the material feed rate. This prevents material from clogging between the distribution plate 7 and the drying belt 1 while allowing the distribution plate 1 to evenly distribute the material to meet the required material placement requirements.

[0041] The motion transmission between the driving member 6 and the distribution plate 7 is realized through the transmission assembly 3. The transmission assembly 3 includes a turntable 31 and a connecting rod assembly 34. The turntable 31 is connected to the output end of the driving member 6 as an active member, and the connecting rod assembly 34 is connected to the distribution plate 7 as a driven member.

[0042] Specifically, the distributor's transmission assembly 3 includes a turntable 31 and a connecting rod assembly 34 eccentrically mounted on the turntable 31. This converts the rotation of the turntable 31 into reciprocating motion of the connecting rod assembly 34 along the length of the distribution plate 7. This sinusoidal mechanism ensures that the stroke of the reciprocating motion is twice the distance from the center of the turntable 31 to the connection point between the connecting rod assembly 34 and the turntable 31. Furthermore, because the connecting rod assembly 34 is detachably connected to the turntable 31, when the distributor is installed on different dryers 8, the stroke of the reciprocating motion of the distribution plate 7 can be changed by simply adjusting the connection point of the connecting rod assembly 34 on the turntable 31. Furthermore, the transmission assembly 3 of this embodiment has no snap-back feature, ensuring that the catalyst is evenly spread during the reciprocating motion of the distribution plate 7.

[0043] In addition, the transmission assembly 3 and the driving member 6 of the distributor should be arranged away from the discharge port of the silo 2 to avoid affecting the normal transportation of materials.

[0044] In some embodiments, the transmission assembly 3 also includes a slider 32 and a guide rod 33. The slider 32 is detachably arranged on the surface of the turntable 31. The guide rod 33 is integrally arranged with the connecting rod assembly 34. A guide groove is opened in the guide rod 33 along the length direction to accommodate the slider 32 sliding in the guide rod 33.

[0045] like Figure 1As shown, the slider 32 can be round or square, and the guide groove in the guide rod 33 can be an elongated groove. The guide groove and the slider 32 can be configured with a clearance fit, ensuring free movement of the slider 32 while reducing friction and wear, thereby ensuring smooth movement and mechanical durability. A guide rail can also be provided in the guide groove to further secure the connection between the slider 32 and the guide rod 33 during sliding.

[0046] The turntable 31 is connected to the connecting rod assembly 34 via a slider 32 and a guide rod 33. The connecting rod assembly 34 can be parallel to the length of the material distribution plate 7, while the guide rod 33 can be perpendicular to the length of the material distribution plate 7. Thus, when the turntable 31 rotates, the slider 32 rotates with the turntable 31 around its center, allowing the connecting rod assembly 34, as a follower, to reciprocate. Due to the positioning of the guide slots in the guide rod 33, the slider 32 simultaneously moves perpendicular to the length of the material distribution plate 7, converting the rotation of the turntable 31 into linear motion of the slider 32. This further allows the connecting rod assembly 34, which is arranged perpendicular to the guide rod 33, to move along its length.

[0047] In some embodiments, the length of the guide slot is greater than or equal to the diameter of the turntable 31 .

[0048] like Figure 1 As shown, the reciprocating stroke of the slider 32 in the guide groove of the guide rod 33 is twice the distance between it and the center of the turntable 31. The slider 32 is detachably mounted on the surface of the turntable 31. Therefore, the theoretical maximum distance between the slider 32 and the center of the turntable 31 can be the radius of the turntable 31, and the length of the guide groove can be set accordingly to the diameter of the turntable 31. The length of the guide groove can preferably be set to be greater than the diameter of the turntable 31 to prevent the end of the guide rod 33 from exerting a force on the slider 32 that affects its movement.

[0049] In some embodiments, the connecting rod assembly 34 includes a first connecting rod and a second connecting rod, the first connecting rod and the second connecting rod are respectively disposed on both sides of the guide rod 33 , and the distribution plate 7 is disposed at the lower end of the guide rod 33 .

[0050] like Figure 1 As shown, the connecting rod assembly 34, the guide rod 33, and the distribution plate 7 can form an integral body, and the distribution plate 7 can be directly connected to the lower end of the guide rod 33, even if the distribution plate 7 and the connecting rod assembly 34 are connected through the guide rod 33. In some other embodiments, the distribution plate 7 can also be spaced apart from the lower end of the guide rod 33. In this case, additional connectors can be provided at both ends of the distribution plate 7, respectively connected to the first connecting rod and the second connecting rod, so as to achieve the connection between the distribution plate 7 and the connecting rod assembly 34.

[0051] To further ensure uniform distribution of material on the distribution plate 7, the distances from both ends of the distribution plate 7 to the guide rod 33 are set equal, that is, the midpoint of the distribution plate 7 is located at the lower end of the guide rod 33 or its extension line. This allows the connecting rod assembly 34 to drive the distribution plate 7 to evenly spread the material across the entire surface of the drying belt 1 during its reciprocating motion. The lengths of the first and second connecting rods are also set to be equal.

[0052] In some embodiments, the turntable 31 is a ring, and the driving member 6 is coaxially arranged with the turntable 31 .

[0053] like Figure 1 As shown, the turntable 31 can be provided with a through hole in the center to form a ring body. The diameter of the through hole can be equal to the diameter of the output end of the driver 6. In this way, the turntable 31 can be sleeved on the output end of the driver 6 to achieve a direct connection between the driver 6 and the turntable 31. The driver 6 and the turntable 31 are coaxially arranged so that the forward and reverse rotation of the driver 6 can be directly transmitted to the turntable 31, achieving synchronous rotation of the driver 6 and the turntable 31, thereby reducing the error of the transmission assembly 3.

[0054] In some embodiments, the end surface of the cloth plate 7 is provided with a comb structure. Figure 1 As shown, the end surface of the cloth plate 7 is provided with a comb structure extending downward, which can increase the gap between the materials and further improve the looseness and air permeability of the materials. The comb structure is preferably arranged at equal intervals on the end surface of the cloth plate 7.

[0055] In some embodiments, a guide assembly 5 is further included, and the connecting rod assembly 34 moves along the length direction of the cloth plate 7 under the action of the guide assembly 5.

[0056] like Figure 2-3 As shown, the guide assembly 5 guides the movement of the connecting rod assembly 34, so that the material distribution plate 7 connected to the connecting rod assembly 34 can move along its own length direction to ensure the laying effect of the material.

[0057] Specifically, the guide assembly 5 may include two support frames, with both ends of the connecting rod assembly 34 supported above the drying belt 1 by the support frames. One end of the support frame is detachably connected to the dryer 8, facilitating assembly and disassembly, allowing the support frame to be used with different dryers 8. The portion of the support frame extending above the drying belt 1 may be provided with a groove, with both ends of the connecting rod assembly 34 slidingly engaged with the groove, allowing the connecting rod assembly 34 to move along the length of the distribution plate 7. The support frame may further be configured to be liftable to adjust the distance between the distribution plate 7 and the drying belt 1.

[0058] In some embodiments, a limiting component 4 is further included, and the limiting component 4 is used to limit the movement range of the cloth plate 7.

[0059] like Figure 2As shown, the limiting assembly 4 can prevent the material from being driven away from the edge of the drying belt 1 due to excessive travel of the material distribution plate 7. The limiting assembly 4 does not contact the material distribution plate 7 during use and mainly plays a protective role.

[0060] In some embodiments, the limiting assembly 4 includes two limiting blocks 41 for being arranged on the dryer 8 , and the two limiting blocks 41 are respectively arranged on the outer sides of the ends of the distribution plate 7 .

[0061] like Figure 2 As shown, two stoppers 41 are respectively disposed on the outer sides of the ends of the material distribution plate 7. The positions of the two stoppers 41 can be designed according to actual needs to avoid excessive travel of the material distribution plate 7. When the material distribution plate 7 contacts the stoppers 41, the driving member 6 stops rotating to prevent the material from escaping from the drying belt 1.

[0062] Specifically, the two limit blocks 41 can be supported on the outer ends of the cloth plate 7 by brackets, wherein one end of the bracket is detachably connected to the dryer 8, facilitating the disassembly and assembly of the bracket, so that the bracket can be used on different dryers 8, saving material costs. Furthermore, the position of the limit block 41 on the bracket can be adjusted. For example, a long hole can be provided on the bracket, and the extension direction of the long hole is consistent with the extension direction of the cloth plate 7. The limit block 41 is fixed to the long hole by bolts. The limit block 41 can be moved along the length direction of the long hole to fix the limit block 41 at different positions of the long hole, making adjustment convenient.

[0063] A second aspect of the present invention provides a material distribution system, comprising:

[0064] A molding machine, wherein a silo 2 is provided at the bottom of the molding machine's discharge port;

[0065] The dryer 8 comprises a rotating drying belt 1, wherein the feed end of the drying belt 1 is located below the discharge end of the silo 2;

[0066] The above-mentioned distributor is used to spread the materials falling onto the drying belt 1.

[0067] like Figure 2-3 As shown, the material discharged from the molding machine passes under the silo 2 and can fall onto the drying belt 1. The dryer 8 has its own motor to drive the drying belt 1 to rotate to realize the transportation of the material.

[0068] The distributor is located below the discharge end of the silo 2 and between the feed end of the drying belt 1, and is preferably arranged above the middle position of the drying belt 1, and is used to spread the material falling onto the drying belt 1, that is, when the material passes through the gap between the distribution plate 7 and the drying belt 1, the material is spread out by the obstruction of the distribution plate 7, and the reciprocating motion of the distribution plate 7 spreads the accumulated material evenly on the drying belt 1.

[0069] During use, the material enters the hopper 2 from the discharge port of the forming machine, and the material in the hopper 7 falls to the top of the drying belt 1 due to gravity. The driving member 6 rotates to drive the distribution plate 7 to move back and forth within a specified range through the transmission assembly 3 to comb the material so that the material is evenly distributed on the drying belt 1.

[0070] Thus far, various embodiments of the present invention have been described in detail. To avoid obscuring the concept of the present invention, some details well known in the art have not been described. Based on the above description, those skilled in the art will fully understand how to implement the technical solutions disclosed herein.
