Description

Technical Field

[0001] This application relates to the technical field of mineral wool production equipment, and in particular to a slag removal and separation device for granular cotton production. Background Technology

[0002] Granular cotton, as an important heat and sound insulation material, requires multiple processing steps during production to ensure product quality. Among these, slag removal and separation is a key step. Effective slag removal can significantly improve the product quality of granular cotton and reduce equipment wear and failure rate in subsequent processing.

[0003] Traditional slag removal and separation equipment mostly relies on gravity sedimentation or simple screening methods to separate slag from granular cotton. For example, it uses screen vibration to filter out larger impurities in granular materials, or it relies on the natural stratification of different substances underwater to achieve slag removal and separation. Moreover, it requires continuous adjustment of the equipment to adapt to the differences in slag content and properties in different batches of raw materials.

[0004] Regarding the aforementioned technologies, underwater separation is time-consuming and requires drying of the granular cotton after separation, increasing energy and time costs. Furthermore, it is difficult to quickly adapt and adjust to different types or materials with significantly varying properties, resulting in less than ideal slag removal and thus limited work efficiency. Summary of the Invention

[0005] To accelerate the efficiency of slag removal and separation, this application provides a slag removal and separation device for granular cotton production.

[0006] This application provides a slag removal and separation device for granular cotton production, which adopts the following technical solution:

[0007] A slag removal and separation device for granular cotton production, comprising:

[0008] A separation channel is provided with a feed inlet on the top wall at one end and a discharge outlet at the end of the separation channel away from the feed inlet.

[0009] A slag removal assembly is installed on the separation channel;

[0010] A pre-separation assembly, which is installed on the separation channel;

[0011] An adjusting component is installed on the slag removal assembly and is used to adjust the slag removal assembly.

[0012] By adopting the above technical solution, in the production process of granulated cotton, the granulated cotton raw material enters from the feed inlet of the separation channel. The granulated cotton raw material first comes into contact with the pre-separation component to pre-treat the granulated cotton raw material, initially screening and separating some easily removable impurities, reducing the workload of the subsequent slag removal component. Then, the slag removal component further separates the impurities from the cotton fibers, effectively realizing the separation of granulated cotton from slag, improving the purity of granulated cotton. The adjustment component can flexibly adjust the slag removal component according to the content and properties of slag in different batches of raw materials and the required separation purity, enhancing the equipment's adaptability to different raw materials.

[0013] Optionally, the slag removal component includes:

[0014] A baffle, which is slidably mounted on the separation channel;

[0015] A blower, which is fixedly installed at one end of the separation channel near the feed inlet;

[0016] A negative pressure fan is installed at one end of the separation channel near the discharge port.

[0017] A slag discharge pipe is connected to the separation channel and is located below the baffle.

[0018] A collection vehicle is positioned below the slag discharge pipe.

[0019] By adopting the above technical solution, the blower blows airflow at the feed inlet of the separation channel, disrupting the distribution of granular cotton and slag. The negative pressure fan at the discharge outlet generates negative pressure, forming a directional channel with the airflow from the blower. After the granular cotton raw material is blown out by the blower, it is blown to the pre-separation component for preliminary treatment, and then blown to the baffle. Under the obstruction of the baffle, the granular cotton raw material falls. The lighter cotton fibers are discharged to the discharge outlet through the airflow, while the slag balls and incompletely fiberized particles sink under the action of gravity and are discharged through the slag pipe, thus achieving effective separation and improving the quality of granular cotton products.

[0020] Optionally, the adjusting element includes:

[0021] An adjusting plate is disposed at the top of the separation channel, the adjusting plate is fixedly connected to the baffle, and the adjusting plate is connected to the pre-separation component;

[0022] An adjusting bolt is threadedly connected to the adjusting plate and to the top wall of the separation channel.

[0023] By adopting the above technical solution, rotating the adjusting bolt causes the adjusting plate to move up and down, thereby allowing the baffle to slide within the separation channel. When the position of the baffle changes, it affects the flow direction and speed of the airflow within the separation channel. For raw materials with high cleanliness, the baffle needs to be moved downwards, allowing the granular cotton raw material to fall freely for a longer time, resulting in less material being drawn into the separation channel by the negative pressure fan, and the separated granular cotton having higher cleanliness. Conversely, for raw materials with low cleanliness, the baffle can be moved upwards, allowing more raw material to rise into the separation channel on the discharge port side. The controllability of the slag removal and separation process is effectively improved through the adjustment components.

[0024] Optionally, the pre-separation component includes:

[0025] The first partition is disposed above the slag discharge pipe. The first partition is parallel to the baffle and located near the feed inlet. The first partition passes through the adjusting plate and is slidably connected to the adjusting plate. The first partition passes through the separation channel and is slidably connected to the top wall of the separation channel. Ventilation holes are provided on the first partition.

[0026] The second partition is arranged parallel to the first partition and located between the first partition and the baffle. The first partition passes through the adjusting plate and is slidably connected to the adjusting plate. The first partition passes through the separation channel and is slidably connected to the top wall of the separation channel.

[0027] A cylindrical cam is located above the separation channel and between the first partition and the second partition, and the cylindrical cam is slidably connected to both the first partition and the second partition;

[0028] The motor has its fixed end fixedly mounted on the adjustment plate, and its output end is coaxially and fixedly connected to the cylindrical cam.

[0029] By adopting the above technical solution, the setting of the first and second partitions can form a preliminary screening area, effectively blocking larger particle impurities from entering the subsequent separation process. When the blower is working, impurities and granular cotton may stick to the baffle, the first partition, and the second partition under the action of wind force. Due to the continuous operation of the blower, impurities and granular cotton will continue to accumulate, affecting the separation efficiency. However, because the motor drives the cylindrical cam to rotate, the rotation of the cylindrical cam will push the first and second partitions to slide up and down alternately, so that impurities and granular cotton will always pass through one of the partitions, achieving the effect of preliminary slag removal and separation. At the same time, because the first and second partitions are constantly rising and falling alternately, the wind force of the blower can be intermittently isolated. When the partition is raised, the wind force can act normally on the material. When the partition is lowered, it blocks the wind force, causing the material accumulated on the baffle to fall off due to the loss of continuous wind force, avoiding material accumulation and ensuring that the separation process is continuously and efficiently carried out.

[0030] Optionally, the pre-separation component further includes:

[0031] The first rotating wheel is rotatably mounted on the top of the side wall of the first partition plate. The first rotating wheel is located on the side of the first partition plate near the cylindrical cam, and the first rotating wheel is slidably connected to the cylindrical cam.

[0032] The second rotating wheel is rotatably mounted on the top of the side wall of the second partition. The second rotating wheel is located on the side of the second partition close to the cylindrical cam, and the second rotating wheel is slidably connected to the cylindrical cam.

[0033] By adopting the above technical solution, the rotation of the cylindrical cam can drive the first and second partitions to slide up and down more smoothly and efficiently with the help of the first and second rotating wheels. This can effectively reduce the friction between the first and second partitions and the cylindrical cam, thereby improving the stability of equipment operation and extending the service life of components.

[0034] Optionally, the slag discharge pipe is constricted along the slag flow direction.

[0035] By adopting the above technical solutions, the downward flow speed of slag can be effectively increased, the residue and blockage of slag in the pipeline can be reduced, and the slag removal efficiency can be improved.

[0036] Optionally, a closure element is provided at the end of the slag discharge pipe away from the separation channel, the closure element comprising:

[0037] A blocking plate is installed at one end of the slag discharge pipe away from the separation channel, and the shape of the blocking plate matches that of the slag discharge pipe;

[0038] A connecting rod, one end of which is fixedly connected to the blocking plate, and the middle section of which is hinged to the slag discharge pipe;

[0039] A retaining ring is fixedly connected to the end of the connecting rod away from the blocking plate;

[0040] A hook frame is fixedly installed on the ground. When the hook frame is in operation, the hook frame passes through the fixing ring.

[0041] By adopting the above technical solution, the blocking plate opens during slag removal and separation, allowing the slag to be smoothly discharged into the collection vehicle, ensuring high efficiency in slag removal. After the collection vehicle is full, the operator uses a ground hook to pass through the fixing ring and pull the connecting rod to rotate the blocking plate, tightly blocking the slag discharge pipe. This prevents slag from spilling when changing collection vehicles, ensuring environmental cleanliness and operational safety. After changing vehicles, the hook is operated in reverse to open the blocking plate and continue slag removal. This closure design allows for flexible opening and closing of the slag discharge pipe, balancing slag removal efficiency and convenient maintenance.

[0042] Optionally, a maintenance rack is provided outside the separation channel.

[0043] By adopting the above technical solutions, the maintenance rack provides maintenance personnel with a stable operating platform, which facilitates the inspection, maintenance and replacement of parts in the separation channel, improves work efficiency, reduces maintenance risks, facilitates regular comprehensive maintenance of equipment, extends equipment service life and ensures production continuity.

[0044] Optionally, the slag discharge pipe is provided with an observation window.

[0045] By adopting the above technical solution and setting an observation window in the slag discharge pipe, operators can directly observe the flow and accumulation of slag inside the pipe, promptly detect problems such as blockage and abnormal accumulation, and take quick measures such as unblocking to ensure a smooth slag removal process.

[0046] In summary, this application includes at least one of the following beneficial technical effects:

[0047] The design of the separation channel, combined with the slag removal and pre-separation components, can effectively remove impurities from granular cotton, improve product purity, and avoid the inefficiency problems caused by traditional gravity sedimentation or simple screening methods.

[0048] The adjustable components can flexibly adjust the working state of the slag removal components, enabling the equipment to quickly adapt to the needs of different batches and different characteristics of raw materials, thereby improving the flexibility and applicability of slag removal.

[0049] The pre-separation component uses a mechanical structure to perform preliminary screening and guidance, reducing the pressure on the main separation stage, thereby optimizing the overall separation efficiency and reducing energy consumption. Attached Figure Description

[0058] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0059] This application discloses a slag removal and separation device for granular cotton production.

[0060] Reference Figure 1 and Figure 2 The slag removal and separation equipment for granular cotton production includes a separation channel 1, a slag removal component 2, a pre-separation component 3, and an adjusting component 4. A feed inlet 11 is provided on the top wall of one end of the separation channel 1, and a discharge outlet 12 is provided at the end of the separation channel 1 away from the feed inlet 11. The slag removal component 2 and the pre-separation component 3 are installed on the separation channel 1, and the adjusting component 4 is installed on the slag removal component 2. The adjusting component 4 is used to adjust the slag removal component 2.

[0061] When using the slag removal and separation equipment for granular cotton production, the granular cotton raw material enters through the feed inlet 11. It is first pre-screened by the pre-separation component 3 to remove some easily separable impurities, reducing the workload of the slag removal component 2. Then, the slag removal component 2 plays its role to further separate the impurities from the cotton fibers, achieving effective separation of granular cotton and slag, and improving product purity. During this process, the slag removal component 2 can be flexibly adjusted through the adjusting component 4 according to the slag content, properties, and separation purity requirements of the raw material, in order to adapt to the slag removal needs of different raw materials and ensure stable and efficient operation of the equipment.

[0062] Reference Figure 1 The separation channel 1 has a rectangular tubular structure and is set horizontally. The inlet 11 of the separation channel 1 is connected to the outlet of the previous production process, and the outlet 12 of the separation channel 1 is connected to the next production process after the granular cotton is separated and slag is removed, so as to carry out subsequent production processing.

[0063] Reference Figure 1 and Figure 2 The slag removal assembly 2 includes a baffle 21, a blower 22, a negative pressure fan 23, a slag discharge pipe 24, and a collection cart 25. The baffle 21 is vertically installed, with its installation direction perpendicular to the raw material flow direction of the separation channel 1. The baffle 21 is slidably installed on the top wall of the separation channel 1. The blower 22 is fixedly installed at one end of the separation channel 1 near the feed inlet 11. The negative pressure fan 23 is installed at one end of the separation channel 1 near the discharge outlet 12. The slag discharge pipe 24 is connected to the separation channel 1 and is located below the baffle 21. The slag discharge pipe 24 is constricted along the slag flow direction and has an observation window 7. The collection cart 25 is located below the slag discharge pipe 24.

[0064] When the slag separation equipment for granular cotton production is in use, the granular cotton raw material enters from the feed inlet 11 of the separation channel 1. The blower 22 near the feed inlet 11 blows out a strong airflow, disrupting the distribution of granular cotton and slag, causing them to be initially separated. At the same time, the negative pressure fan 23 generates negative pressure, forming a directional airflow channel with the airflow blown out by the blower 22. After being blown out by the blower 22, the granular cotton raw material continues to move forward. Under the action of the airflow, the granular cotton and some impurities move to the baffle 21, blocking the granular cotton raw material and causing it to fall. At this time, the lighter cotton fibers are discharged towards the discharge outlet 12 along the airflow under the suction of the negative pressure fan 23, while the heavier materials such as slag balls and incompletely fibrous particles sink under the action of gravity and are discharged through the slag discharge pipe 24 located below the baffle 21. The slag discharged from the slag discharge pipe 24 falls into the collection car 25 below for subsequent centralized processing.

[0065] The slag discharge pipe 24 is constricted along the direction of slag flow, which increases the flow speed of slag in the pipe, reduces slag residue and blockage in the pipe, and effectively improves slag removal efficiency. Operators can observe the flow and accumulation of slag in the pipe in real time through the observation window 7 set on the slag discharge pipe 24. Once blockage or abnormal accumulation is found, measures such as unblocking can be taken quickly to ensure the smooth progress of the slag removal process.

[0066] Reference Figure 1 The adjusting component 4 includes an adjusting plate 41 and an adjusting bolt 42. The adjusting plate 41 has a rectangular plate structure and is arranged parallel to the top wall of the separation channel 1. The adjusting plate 41 is located at the top of the separation channel 1, and is fixedly connected to the baffle 21. The adjusting plate 41 is connected to the pre-separation component 3, and the adjusting bolt 42 is threadedly connected to the adjusting plate 41 and the top wall of the separation channel 1.

[0067] When using the slag removal and separation equipment for granular cotton production, the operator can adjust the adjusting bolt 42 according to the characteristics of the batch of granular cotton raw materials, such as slag content, particle size, and the desired separation effect. When the operator rotates the adjusting bolt 42, the adjusting plate 41 will move up and down under the action of the bolt, and the adjusting plate 41 will drive the baffle 21 to slide up and down in the separation channel 1.

[0068] If the raw material contains less slag and has a smaller particle size, and a higher separation purity is required, the operator can rotate the adjusting bolt 42 downwards, causing the adjusting plate 41 to move the baffle 21 downwards. This increases the free fall time of the granular cotton raw material and reduces the time it is affected by airflow during its fall, thus reducing the amount of material drawn into the separation channel 1 by the negative pressure fan 23, thereby improving the cleanliness of the separated granular cotton. Conversely, if the raw material contains more slag and has a larger particle size, and the separation purity requirement is relatively lower, the operator can rotate the adjusting bolt 42 upwards, causing the adjusting plate 41 to move the baffle 21 upwards. More raw material will then be able to rise into the separation channel 1 on the side of the discharge port 12 under the action of airflow, improving processing efficiency.

[0069] The regulating plate 41 is also connected to the pre-separation component 3. While adjusting the position of the baffle 21, it will also have a certain impact on the working state of the pre-separation component 3, making the coordination between the pre-separation component 3 and the slag removal component 2 more precise, and further optimizing the overall slag removal process.

[0070] Reference Figure 2 and Figure 3 The pre-separation component 3 includes a first partition 31, a second partition 32, a cylindrical cam 33, a motor 34, a first rotating wheel 35, and a second rotating wheel. The first partition 31 is disposed above the slag discharge pipe 24. The first partition 31 is parallel to the baffle 21 and located near the feed inlet 11. The first partition 31 passes through the adjusting plate 41 and is slidably connected to the adjusting plate 41. The first partition 31 passes through the separation channel 1 and is slidably connected to the top wall of the separation channel 1. A ventilation hole 311 is provided on the first partition 31.

[0071] Reference Figure 2 and Figure 3 The second partition 32 is arranged parallel to the first partition 31 and is located between the first partition 31 and the baffle 21. The first partition 31 passes through the adjusting plate 41 and is slidably connected to the adjusting plate 41. The first partition 31 passes through the separation channel 1 and is slidably connected to the top wall of the separation channel 1. The cylindrical cam 33 is located above the separation channel 1 and between the first partition 31 and the second partition 32. The cylindrical cam 33 is slidably connected to both the first partition 31 and the second partition 32. The curved annular protrusion on the cylindrical cam 33 causes the first partition 31 and the second partition 32 to slide up and down alternately. The fixed end of the motor 34 is fixedly installed on the adjusting plate 41, and the output end of the motor 34 is coaxially fixedly connected to the cylindrical cam 33.

[0072] Reference Figure 2 and Figure 3There are two first rotating wheels 35, both of which are rotatably mounted on the top of the side wall of the first partition 31. The first rotating wheels 35 are located on the side of the first partition 31 near the cylindrical cam 33. The two first rotating wheels 35 are respectively slidably mounted on the upper and lower sides of the curved annular protrusion of the cylindrical cam 33. There are two second rotating wheels 36, both of which are rotatably mounted on the top of the side wall of the second partition 32. The second rotating wheels 36 are located on the side of the second partition 32 near the cylindrical cam 33. The two second rotating wheels 36 are respectively slidably mounted on the upper and lower sides of the curved annular protrusion of the cylindrical cam 33.

[0073] When the slag removal and separation equipment for granular cotton production is in use, the motor 34 starts and drives the cylindrical cam 33 to start rotating. The curved annular protrusion on the cylindrical cam 33 plays a key role. During the rotation of the cylindrical cam 33, the first rotating wheel 35 and the second rotating wheel 36 are pushed and rolled along with it due to their sliding connection with the curved annular protrusion, which in turn drives the first partition 31 and the second partition 32 connected to it to slide up and down alternately.

[0074] After the granular cotton raw material enters the separation channel 1 through the feed inlet 11, under the action of the airflow from the blower 22, some of the raw material first contacts the first partition 31. The first partition 31 has ventilation holes 311, which block larger particles of impurities. The granular cotton and smaller impurities pass through the ventilation holes 311 and continue to move forward. Some of the raw material first contacts the second partition 32, and is separated once by falling under the obstruction of the second partition 32. During this process, due to the alternating rise and fall of the partitions, the airflow from the blower 22 can be intermittently isolated, preventing impurities and granular cotton from accumulating on the baffle 21, the first partition 31, and the second partition 32 under the action of the airflow due to the continuous operation of the blower 22, thus affecting the separation efficiency. When the partitions rise, the raw material attached to the windward side of the partitions can fall quickly. When the second partition 32 falls, it blocks the airflow, causing the material accumulated on the baffle 21 to fall off due to the loss of continuous airflow, ensuring that the separation process continues to be efficient.

[0075] At the same time, if the adjusting plate 41 moves up and down due to the action of the adjusting bolt 42, the overall position of the entire pre-separation component 3, including the first partition 31, the second partition 32, the motor 34, the cylindrical cam 33, and the rotating wheel, will also change. In turn, the pre-separation effect will be optimized synchronously according to the adjustment of the slag removal component 2, ensuring that the entire slag removal and separation process is smooth and efficient.

[0076] Reference Figure 2A closure element 5 is provided at the end of the slag discharge pipe 24 away from the separation channel 1. The closure element 5 includes a blocking plate 51, a connecting rod 52, a fixing ring 53, and a hook 54. The blocking plate 51 is installed at the end of the slag discharge pipe 24 away from the separation channel 1. The shape of the blocking plate 51 matches that of the slag discharge pipe 24. The connecting rod 52 is Z-shaped. One end of the connecting rod 52 is fixedly connected to the blocking plate 51, and the middle section of the connecting rod 52 is hinged to the slag discharge pipe 24. The fixing ring 53 is fixedly connected to the end of the connecting rod 52 away from the blocking plate 51. The hook 54 is vertically fixed on the ground. The position of the hook 54 matches the position of the fixing ring 53. When the hook 54 is in action, the hook 54 passes through the fixing ring 53.

[0077] When the equipment is in operation and performing slag removal, the blocking plate 51 is in the open state. At this time, the slag separated from the separation channel 1 can be discharged into the collection car 25 below through the slag discharge pipe 24. When the collection car 25 is full and needs to be replaced, the operator inserts the fixing ring 53 into the hook frame 54. When the hook frame 54 is inserted into the fixing ring 53 and pulled down, the connecting rod 52 rotates around the hinge point with the slag discharge pipe 24, causing the blocking plate 51 to rotate around the hinge point. The blocking plate 51 rotates until it is tightly fitted with the opening of the slag discharge pipe 24, thereby completely blocking the slag discharge pipe 24, preventing slag leakage during the replacement of the collection car 25, maintaining a clean working environment, and ensuring operational safety.

[0078] After the collection vehicle 25 is replaced, the operator reverses the operation of the hook frame 54, pulls out the fixing ring 53 from the middle hook frame 54 and lowers it. At this time, the blocking plate 51 rotates in the opposite direction around the hinge point under the action of gravity and its own structure, reopening the slag discharge pipe 24, so that the equipment can continue to carry out slag removal operations. The entire closure part 5 is simple and convenient to operate, effectively balancing slag removal efficiency and equipment maintenance convenience.

[0079] Reference Figure 1 A maintenance frame 6 is installed outside the separation channel 1, and a maintenance ladder and auxiliary equipment are installed on the maintenance frame 6. When the equipment needs maintenance, maintenance personnel can climb to a suitable position via the maintenance ladder on the maintenance frame 6, which provides a stable standing platform for maintenance personnel to inspect, maintain and replace parts of various components in the separation channel 1, or operate the adjustment component 4 to adjust the operating status of the equipment.

[0080] The implementation principle of the slag removal and separation equipment for granular cotton production in this application embodiment is as follows: Granular cotton raw material enters from the feed inlet 11 of the separation channel 1, and is first pre-screened by the pre-separation component 3. The first baffle 31 and the second baffle 32 are alternately raised and lowered by the motor 34 to block large particle impurities and intermittently isolate the air force of the blower 22 to prevent material accumulation. Then the slag removal component 2 works, and the blower 22 and the negative pressure fan 23 cooperate to form an airflow channel. The baffle 21 blocks the material, so that the cotton fiber and slag are separated. The slag is discharged into the collection vehicle 25 through the constricted slag discharge pipe 24. The operator can monitor the slag discharge through the observation window 7.

[0081] Operators can rotate the adjusting bolt 42 according to the characteristics of the raw materials, and drive the baffle 21 to move up and down through the adjusting plate 41 to adapt to different slag removal requirements. At the same time, the linkage of the pre-separation component 3 optimizes the synergistic effect. The closing part 5 at the end of the slag discharge pipe 24 can be conveniently sealed when the collection vehicle 25 is full. It can be opened again after replacement. The maintenance frame 6 and maintenance ladder outside the separation channel 1 provide convenience for equipment maintenance, ensuring the stable and efficient operation of the equipment in all aspects, realizing precise slag removal of different raw materials, and improving the separation efficiency of granular cotton.

[0082] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
