Description

Technical Field

[0001] The present invention relates to the technical field of granulation equipment, and particularly relates to a granulation equipment. Background Art

[0002] A granulation equipment is a forming equipment that can form materials into specific shapes and can prepare materials into granular structures. For example, when repairing heavy metal-polluted soil, a modification material can be added to the soil to transform heavy metals into low-soluble, fixed, and low-toxic forms, so as to reduce the availability and environmental risk of heavy metals in the polluted soil. However, most soil passivation materials are powdery solid particles. During agricultural production, it is very difficult to add them to the soil like fertilizers because some passivation materials may be light in texture, such as modified fly ash. Under natural wind, they will form dust and cannot be evenly and effectively added to the soil, thus unable to stably repair heavy metal-polluted soil. When the soil passivation materials are prepared into granular structures by a granulation equipment, it is convenient to repair the soil.

[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] The embodiment of the present invention provides a granulation device, as Figure 1 shown. This granulation device includes a mixing device 1, a pushing device, a forming device 3, and a drying device 4 that are sequentially arranged from top to bottom. Among them, the mixing device 1 includes a mixing tank 11 and a stirring part 12 arranged in the mixing tank 11. The mixing tank 11 is provided with a feeding port 13. The stirring part 12 can stir and mix the materials added into the mixing tank 11. The pushing device is used to push the stirred and mixed materials into the forming device 3. The forming device 3 can form the mixed materials into granular shapes, and then the drying device 4 dries the granular materials to make their shapes stable.

[0034] Among them, the materials include solid materials and liquid materials. The solid materials can be powdery materials or granular materials, and the liquid materials can be medicaments for mixing with the solid materials, or the liquid materials can also be liquids only used to assist in the molding of the fixed materials, without specific limitations here.

[0035] Specifically, the molding device 3 includes a driving part, a molding plate 33 and a scraper 35. Among them, the molding plate 33 is provided with molding holes 34. The scraper 35 can move along the lower end surface of the molding plate 33 under the driving action of the driving part. The pushing device can push the materials after being mixed by the mixing device 1 to the molding device 3 and extrude the mixed materials onto the molding plate 33. Under the action of the extrusion force, the materials can enter the molding holes 34 and pass through the molding plate 33 through the molding holes 34 to form strip-shaped materials adapted to the shape of the molding holes 34. Then the scraper 35 can move along the end surface of the molding plate 33 and cut off the strip-shaped materials from the lower end surface of the molding plate 33 to obtain material particles. The drying device 4 is located below the molding device 3. After the material particles are cut by the scraper 35, they will automatically fall into the drying device 4 under the action of gravity. The drying part 41 of the drying device 4 can dry the material particles to make their state stable, so as to avoid the situation of adhesion or deformation between the later particle materials.

[0036] During the granulation of the materials by this granulation equipment, the mixing device 1 automatically stirs and mixes the materials, and then the pushing device automatically pushes the mixed materials to the molding device 3 to form material particles. The drying part 41 dries the material particles. The structure is simple and the degree of automation is high, without manual operation, effectively reducing costs. Moreover, the mixing device 1, the pushing device, the molding device 3 and the drying device 4 are arranged in sequence from top to bottom, which can effectively reduce the overall occupied space and is convenient for on-site layout.

[0037] Specifically, in this embodiment, there is no limitation on the pushing device. Its main function is to push the mixed materials to the molding device 3. The pushing device can be set as a spiral pushing rod 2. The spiral pushing rod 2 is located below the mixing device 1. A switching valve is provided at the bottom of the mixing device 1. When the materials in the mixing device 1 are mixed evenly, the switching valve is opened, and the materials fall from above into the spiral pushing rod 2. The spiral pushing rod 2 can push the mixed materials to the molding device 3 through the spiral extrusion force, and the structure is relatively simple.

[0038] Such as Figure 2As shown, the mixing device 1 further includes a liquid material tank 14, a metering pump 15 and pipelines. Among them, the liquid material tank 14 is used to store liquid materials. The pipelines are connected between the liquid material tank 14 and the mixing tank 11. Multiple nozzles 16 are provided on the pipelines. The metering pump 15 is used to control the flow rate of the liquid materials in the pipelines, so as to accurately control the addition amount of the liquid materials sprayed into the mixing tank 11 from the nozzles 16. The feeding port 13 is also provided with an inclined plate 131 and an inclined plate motor 132. Among them, the inclined plate motor 132 can drive the inclined plate 131 to move to adjust the opening degree of the feeding port 13, so as to adjust the addition amount of the solid materials, thereby ensuring the accuracy, uniformity and consistency of the components of the mixed materials. That is to say, the solid materials are added from the feeding port 13, and the liquid agents are sprayed from the nozzles 16. The addition amounts of each can be accurately controlled, and then they are stirred and mixed by the stirring part 12.

[0039] Moreover, when granulating materials with different ratios or different components, cleaning water can be placed in the liquid material tank 14 first, and the metering pump 15 is used to control and increase the flow rate of the cleaning water in the pipelines, so as to realize the cleaning of the liquid material tank 14, the pipelines and the mixing tank 11. And because the cleaning water will flow downward under its own gravity to the forming device 3 and the drying device 4 to complete the cleaning. During this process, there is no need for manual cleaning operation, and the automation degree is high and it is easy to use.

[0040] As Figure 3 shown, the forming plate 33 is provided with at least two rows of forming holes 34 along a preset direction. The driving part includes a driving member and a driving rod 32. Among them, the driving rod 32 is fixed to the scraper 35. The driving member can drive the driving rod 32 to move along the end face of the forming plate 33 in the preset direction, so as to drive the scraper 35 to move along the end face of the forming plate 33 in the preset direction to cut the strip-shaped materials passing through the forming holes 34. Specifically, the driving holes are arranged in at least two rows. During the movement of the scraper 35, it can cut the materials at one row of forming holes 34 at the same time. Such a setting can improve the material cutting efficiency. Specifically, the number of rows of the forming holes 34 and the number of forming holes 34 provided in each row of the forming holes 34 are not limited. At the same time, the number of the scrapers 35 is also not limited. As Figure 3 shown, the number of the scrapers 35 can be the same as the number of rows of the forming holes 34, and each scraper 35 is arranged in parallel along the preset direction. Such a setting can ensure that each scraper 35 only needs to cut the materials at one row of forming holes 34 under the action of the driving part to complete this cutting. In this way, it can ensure that the sizes of the material particles cut in the same batch are the same, and the cutting efficiency is relatively high.

[0041] Specifically, in this embodiment, the specific structure of the driving member is not limited. As Figure 3As shown, the driving member is a motor. The driving rod 32 includes a rack structure. The motor can cooperate with the rack structure through a gear to drive the driving rod 32 to move. Alternatively, the driving rod 32 can also be arranged to include a lead screw structure, and the motor cooperates with the lead screw through a nut to drive the lead screw to move in a preset direction. Specifically, the number of driving parts is two. The driving rods 32 of the two driving parts are arranged in parallel, and the driving directions of the two driving parts are opposite. As Figure 3 shown, the two driving rods 32 can move in two opposite directions respectively under the driving action of the motors they cooperate with. The two driving rods 32 are both arranged parallel to the above preset direction, so as to drive the scraper 35 to reciprocate along the end face of the forming plate 33 to cut the material. In this way, two single-direction motors can be selected. Of course, the reciprocating movement of the scraper 35 can also be realized by a two-way motor. The setting of two single-direction motors can reduce the requirements for the motor. The two single-direction motors work intermittently, which can extend the service life of a single motor and enhance the reliability of the equipment. Alternatively, in this embodiment, the driving member can also be set as a cylinder, a hydraulic cylinder, etc.

[0042] The forming plate 33 and the driving part are detachably connected. In this way, when the particle sizes or shapes of the required material particles are different, the forming plate 33 provided with corresponding forming holes 34 can be replaced, and the driving part and the scraper 35 do not need to be replaced, which has good flexibility.

[0043] The forming device 3 further includes a laser sensor 36. The laser sensor 36 is arranged on the lower end face of the forming plate 33 and is used to monitor the length of the strip-shaped material, so that the sizes of the material particles after being cut by the scraper 35 are consistent. Alternatively, the driving part can also cut the material according to a set time interval. There is no specific limitation here.

[0044] As Figure 2 and Figure 4 shown, the drying device 4 includes a collecting plate 42 and a conveying trough 43. Among them, the collecting plate 42 is located below the forming device 3. The upper end face of the collecting plate 42 is provided with an inclined surface. After the material particles fall onto the collecting plate 42, they can move along the inclined surface under their own gravity to the conveying trough 43. The conveying trough 43 includes a plurality of parallel slideways 44. The granular material can move along the inclined surface into each slideway 44 and slide along each slideway 44 to realize conveying. Since the slideways 44 are arranged side by side, when the granular material enters the conveying trough 43, it can enter each slideway 44 respectively, avoiding the situation that most of the material particles stick together during the sliding process along the conveying trough 43.

[0045] As Figure 2 and Figure 4As shown in the figure, the conveying trough 43 is arranged in a spiral structure, and the width of the slideway 44 also gradually narrows from top to bottom. The top ends of the slideways 44 are connected to the collecting plate 42. The material particles can slide from the inclined surface to the top ends of the slideways 44 under their own gravity and slide spirally from top to bottom along the slideways 44. Due to the spiral sliding, the slope is gentle, which can prevent the mutual extrusion between the material particles in the same slideway 44. The side walls of the slideway 44 can interact with the material particles. Through the friction between the material particles and the friction between the side walls of the slideway 44 and the material particles, the edges and corners of the material particles can be polished, so that when the material particles slide to the bottom along the slideway 44, the edges and corners are basically ground flat, forming a spherical or ellipsoidal structure. In this way, compared with the material particles with edges and corners, it is convenient for later use. Since the width of the slideway 44 gradually narrows, during the process of the material particles sliding along the slideway 44, the side walls of the slideway 44 can strengthen the action on the material particles, which is conducive to polishing the edges and corners of the material particles.

[0046] Moreover, during the process of the material particles sliding along the slideway 44, the drying part 41 can dry the material particles. Therefore, the spiral slideway 44 with a gentle slope can increase the action time of the drying part 41 and ensure the drying effect, so that the material particles can form stable material particles when sliding to the bottom of the slideway 44. Specifically, the drying part 41 can be a hot air blower for blowing hot air into the drying device 4 to dry the material particles, or the drying part 41 can also be a heating device arranged on the side wall of the slideway 44. For example, heating wires are arranged inside the side wall and bottom wall of the slideway 44, and the material particles can be dried by heating with the heating wires. There is no specific limitation here.

[0047] As Figure 1 As shown in the figure, the granulating equipment also includes a vibrating sieve device 5 connected to the drying device 4. The materials in the drying device 4 are dried and formed stably during the process of sliding along the slideway 44, and then enter the vibrating sieve device 5 through the slideway outlet 441 and the conveying part 7 for screening. Specifically, the vibrating sieve device 5 includes two layers of sieve meshes 51 and one layer of aggregate plate 52. Among them, the two layers of sieve meshes 51 are located above the aggregate plate 52, and the aperture of the sieve mesh 51 located above is larger than that of the sieve mesh 51 located below. With such a setting, after the materials enter the vibrating sieve device 5, the larger particle materials will be filtered by the upper sieve mesh 51 and remain on the upper sieve mesh 51, while the smaller particle materials will pass through the second sieve mesh 51 and fall to the aggregate plate 52. The size of the material particles remaining on the second sieve mesh 51 meets the requirements, ensuring the uniformity and consistency of each material particle, and can enter the next sub-packaging operation. Specifically, the second sieve mesh 51 can be inclined, and the side facing the sub-packaging device 6 is lower than the side facing the drying device 4, so as to facilitate the movement of the material particles to the sub-packaging device 6 under their own gravity.

[0048] The vibrating screen device 5 further includes a recovery box 53 , which is located below the collecting plate 52 . The material particles in the uppermost screen 51 and the material particles collected by the collecting plate 52 can be transported to the recovery box 53 for unified recovery and processing.

[0049] like Figure 1 As shown, the granulation equipment further includes a packaging device 6, which is arranged after the vibrating screen device 5 and can pack the material particles with the required particle size into packaging bags. Specifically, Figure 5 As shown, the packaging device 6 includes a bracket 61 and a rotating shaft 62, a shearing part 63, an action part 64 and a sewing part 65 arranged on the bracket 61, wherein the rotating shaft 62 is rotatably connected to the bracket 61, and the outer wall of the rotating shaft 62 is wrapped with a bag roll 66, the top of the action part 64 can penetrate the open end 661 of the bag roll 66 and drive the open end 661 to move downward, the shearing part 63 is located above the action part 64, and is used to cut the bag roll 66 along the horizontal direction to form an independent packaging bag, and the sewing part 65 is located below the action part 64, and the sewing part 65 can sew the opening of the packaging bag (specifically including the upper opening and the lower opening) along the horizontal direction.

[0050] When the bag is packed, the top of the bag roll 66 is moved downwardly by the action part 64, and the action part 64 is moved downwardly by the action part 64. When the bag roll 66 is packed, the top of the action part 64 is moved downwardly by the action part 64, and the action part 64 is moved downwardly by the action part 64. When the bag roll 66 is packed, the action part 64 is moved downwardly by the action part 64, and the action part 64 is moved downwardly by the action part 64. When the bag roll 66 is packed, the action part 64 is moved downwardly by the action part 64. When the bag roll 66 is packed, the action part 64 is moved downwardly by the action part 64. When the bag roll 66 is packed, the action part 64 is moved downwardly by the action part 64.

[0051] The bag roll 66 can be automatically cut into individual packaging bags by the packaging device 6. After the materials are placed in the packaging bags, the packaging bags can be sewn together. This has a high degree of automation and eliminates the need for manual bag handling, saving time and effort and achieving high efficiency. Due to the automated operation, the size of each packaging bag can be guaranteed to be consistent, ensuring good product consistency. At the same time, it can also avoid dust pollution during the material packaging operation, which poses a health hazard to workers and improves safety.

[0052] In the above embodiment, if Figure 5As shown, the sub-packaging device 6 further includes a tray 67, which is disposed below the sewing part 65. After the lower opening of the packaging bag is sewn by the sewing part 65, the actuating part 64 can continue to act on the packaging bag to move it downward until the bottom of the packaging bag abuts against the tray 67. At this time, when adding materials into the packaging bag, the tray 67 can provide support for the packaging bag, thereby reducing the requirement for the force between the actuating part 64 and the packaging bag.

[0053] The actuating part 64 includes a telescopic assembly 641. The telescopic assembly 641 includes two mutually intersecting telescopic rods 6411. Driving wheels 642 are respectively arranged at both ends of each telescopic rod 6411. The driving wheels 642 can be attached to the inner wall of the packaging bag, and the driving wheels 642 can drive the packaging bag to move downward by rotation. Of course, in this embodiment, the specific structure of the actuating part 64 is not limited. For example, the actuating part 64 may also be provided with a moving member that can move in the vertical direction and drive the packaging bag to move downward. When the driving wheels 642 drive the packaging bag to move by rotation, the driving wheels 642 are attached to the inner wall of the packaging bag, and the middle position is supported by the telescopic rods 6411, which can expand the packaging bag while not affecting the loading of materials into the packaging bag. Moreover, the telescopic rods 6411 can also adjust their lengths by telescoping, thereby adjusting the opening of the packaging bag and being suitable for packaging bags of different sizes and specifications, with good flexibility.

[0054] Furthermore, the actuating part 64 further includes a guiding member 643. The number of telescopic assemblies 641 is two groups, and the two groups of telescopic assemblies 641 are arranged at intervals along the axial direction of the guiding member 643. The axial direction of the guiding member 643 is arranged along the vertical direction. The arrangement of the guiding member 643 can provide guidance for the two groups of telescopic assemblies 641, so that the central positions of the telescopic rods 6411 are on the same vertical axis. The two groups of telescopic assemblies 641 act on the packaging bag simultaneously, which can improve the acting force of the actuating part 64. Moreover, the two groups of telescopic assemblies 641 are arranged at intervals in the height direction. The two telescopic rods 6411 of the upper telescopic assembly 641 are both in the extended state to evenly expand the passing packaging bag. The lower telescopic assembly 641 can contract one telescopic rod 6411 and extend the other telescopic rod 6411 to support the opening of the packaging bag to form a long strip shape, and then the sewing part 65 can sew along the long strip shape, which is convenient for sewing operation.

[0055] Further, four guide rods 644 are also connected between the two sets of telescopic components 641. The end portions of each telescopic rod 6411 are respectively connected to one guide rod 644. That is to say, each set of telescopic components 641 includes two guide rods 644. These two guide rods 644 have four end portions, and each end portion is respectively connected to one guide rod 644 correspondingly. A plurality of the above-mentioned driving wheels 642 are arranged along the axial direction of each guide rod 644. With such a setting, the number of driving wheels 642 can be further increased, and thus the driving force of the actuating portion 64 on the packaging bag can be increased.

[0056] As Figure 6 and Figure 7 shown, each guide rod 644 is also provided with a driving motor 645, a transmission rod 646, a transmission gear 647 and a transmission shaft 648. Among them, the transmission shaft 648 is in coaxial transmission with the driving wheel 642. The transmission gear 647 is arranged between the transmission rod 646 and the transmission shaft 648. The driving motor 645 can drive the transmission rod 646 to rotate. The rotation of the transmission rod 646 can drive the transmission shaft 648 to rotate through the transmission gear 647, and further drive the driving wheel 642 to rotate. As Figure 7 shown, the guide rod 644 includes a frame structure. One side frame of the frame structure can rotate along its axial direction, and this side frame forms the above-mentioned transmission rod 646. The driving motor 645 can directly drive the transmission rod 646 to rotate or drive the transmission rod 646 to rotate through gear transmission. The rotation of the transmission rod 646 can drive the transmission shaft 648 to rotate through the transmission gear 647. With such a setting, all the driving wheels 642 located on the same guide rod 644 can be driven to rotate by one driving motor 645, and the overall structure can be simplified. Specifically, the transmission gear 647 can be a single gear or a gear set of multiple gears, and no specific limitation is made here.

[0057] As Figure 5 shown, the dispensing device 6 further includes a guiding portion 68. The guiding portion 68 is located between the rotating shaft 62 and the shearing portion 63. Specifically, the guiding portion 68 is located inside the opening end 661 of the bag roll 66 to expand the opening end 661 of the bag roll 66. The shearing portion 63 is arranged below the guiding portion 68. After the shearing portion 63 shears the bag roll 66 to form a packaging bag, the guiding portion 68 is always located inside the bag roll 66. With such a setting, after the shearing portion 63 shears, the opening end 661 of the bag roll 66 is always in an expanded state, which is convenient for the actuating portion 64 to enter the opening end 661 of the bag roll 66. Moreover, the guiding portion 68 can also drive the opening end 661 of the bag roll 66 to move downward until the actuating portion 64 enters the opening end 661 of the bag roll 66, and the whole process does not require manual operation, with a high degree of automation.

[0058] In the above embodiment, the packing device 6 further includes a feeding part 69 and a driving member. The discharging port of the feeding part 69 is located between the shearing part 63 and the operating part 64. The feeding part 69 is used to add materials into the upper opening of the packaging bag. Specifically, the feeding part 69 includes an upper baffle 691 and a lower baffle 693. Both the upper baffle 691 and the lower baffle 693 are used to block the materials and form a material storage area 692 therebetween. The driving member can drive the upper baffle 691 and the lower baffle 693 to move respectively to open and close the material storage area 692.

[0059] That is to say, before the materials enter the packaging bag along the feeding part 69, they can be pre-stored in the material storage area 692. When the upper baffle 691 is opened and the lower baffle 693 is closed, at this time, the materials can enter the material storage area 692 for temporary storage. When they cannot enter the packaging bag, when the materials in the material storage area 692 reach a certain amount, the driving member drives the upper baffle 691 to close and opens the lower baffle 693. At this time, the external materials cannot enter the material storage area 692, and a certain amount of materials temporarily stored in the material storage area 692 can be fed into the packaging bag. Then, the driving member drives the lower baffle 693 to close and the upper baffle 691 to open, and the external materials enter the material storage area 692 for temporary storage again to prepare for filling the next packaging bag.

[0060] With such a setting, the amount of materials entering each packaging bag can be made the same, which can be completed without manual operation, saving time and being highly efficient with good product consistency. Moreover, when the operating part 64 drives the packaging bag to move downward or the sewing part 65 is sewing the packaging bag, the materials can be prepared in the material storage area 692, saving time and being highly efficient. Specifically, there is no limitation on the specific structure of the driving member. For example, it can be set as a cylinder, a hydraulic cylinder or a motor screw rod, etc. And the driving member can be set to one, and the upper baffle 691 and the lower baffle 693 are driven to lift by one driving member, or the number of driving members can also be set to two, and the upper baffle 691 and the lower baffle 693 can be driven to lift respectively.

[0061] A weighing unit 695 is further provided at the bottom of the material storage area 692. When the weighing result of the weighing unit 695 indicates that the materials in the material storage area 692 reach the preset target, the upper baffle 691 seals the material storage area 692, and the driving member can open the lower baffle 693. Or, a position sensor 696 is further provided on the lower baffle 693. When the materials in the material storage area 692 reach a certain height, the position sensor 696 can know the height of the materials, and the lower baffle 693 can be opened under the action of the driving member. Or, in this embodiment, it can also be that while a weighing sensor is provided in the material storage area 692, a position sensor 696 is provided on the lower baffle 693. With such a setting, it can be ensured that the amount of materials packed in each packaging bag is consistent and the accuracy is high.

[0062] In summary, when the material is packaged by the packaging device 6, the open end 661 of the bag roll 66 moves downward under the action of the guide part 68 until the top of the action part 64 extends into the open end 661, and then the action part 64 drives the open end 661 to continue to move downward to the preset position, and the action part 64 stops the action, and one telescopic rod 6411 of the telescopic assembly 641 below extends and the other telescopic rod 6411 contracts, so that the open end 661 forms a long strip shape, and the sewing part 65 sews it, and then the retracted telescopic rod 6411 extends, and the action part 64 continues to act until the sewn open end 661 abuts against the tray 67 below, and the shearing part 63 cuts the bag roll 66 from above (or, in this embodiment, a laser position sensor 696 can also be provided, The position of the open end 661 of the bag roll 66 is monitored, and the bag roll 66 is cut by the shearing unit 63, so that the lower portion forms an independent packaging bag. At this time, the bottom of the packaging bag is sewn, and the top is held open by the telescopic assembly 641 of the action unit 64. In the above-mentioned process of forming an independent packaging bag, a certain amount of material is stored in the material storage area 692 of the feeding unit 69. Then, the lower material baffle 693 is driven by the driving member to move to open the material storage area 692, so that the material in the material storage area 692 enters the packaging bag along the top opening of the packaging bag. Then, one telescopic rod 6411 of the telescopic assembly 641 located at the top opening of the packaging bag is extended and the other telescopic rod 6411 is retracted, so that the top of the packaging bag is formed into a long strip. It is sewn by the sewing unit 65 to complete the packaging of a bag of materials. It is not difficult to understand that when the sewing unit 65 is sewing the upper opening of the packaging bag, the telescopic rod 6411 still provides support for the upper opening of the packaging bag. Therefore, the sewing position is located below the telescopic rod 6411. After the materials are packaged, they can be transported to the designated location through the conveying unit 7.

Operation is performed by a program set by a single-chip microcomputer, and the equipment can be monitored and managed via an application and the internet, using a remote terminal, etc., in line with the "Intelligent Internet of Things" design concept. However, controlling the operation of the various electrical components through programs is well known to those skilled in the art and will not be further described here to save space. In other words, the entire granulation equipment constitutes a complete industrial production line with a high degree of automation.
