Description

Technical Field

[0001] This invention relates to the field of filling devices, and more specifically to a sagger filling device. Furthermore, it relates to a sagger filling method using this sagger filling device. Background Technology

[0002] In industrial production, materials often need to be roasted. For fine granular solid materials, high-temperature resistant saggers are typically used to hold the material before it enters the roasting furnace. For some materials, excessive or insufficient roasting can result in substandard products. Therefore, multiple smaller saggers are usually fed into the furnace to ensure that each sagger contains a smaller amount of material, allowing for simultaneous heating and roasting of both the internal and external materials. The amount of material in each sagger determines the roasting time, and the consistency of the material content in multiple saggers roasting simultaneously determines the quality of the batch. Traditional filling methods typically involve manual filling, which is time-consuming and labor-intensive, resulting in poor material precision control. Therefore, an automated sagger filling device with automatic filling and quantity control is needed.

[0003] Chinese utility model patent CN214933512U discloses a device for filling a sagger with powdered material. It uses vibration feeding and sieving to feed granular material, and adjusts the discharge height via a lifting column to achieve automatic filling and control of the filling amount. However, in actual roasting processes, especially with granular catalyst carriers and other materials sensitive to roasting degree, the material still has thickness in the sagger. The central part of the material in the sagger receives less roasting than the surface part directly in contact with the roasting furnace environment, resulting in uneven roasting and a decrease in the quality of the finished product. To solve this problem, existing technologies generally reduce the thickness of the material in the sagger to ensure more uniform roasting. However, this reduces the amount of material that can be roasted at one time, thus reducing the efficiency of the entire production line.

[0004] Therefore, a device is needed that can evenly distribute the material inside the sagger so that the material can be roasted evenly. Summary of the Invention

[0005] The purpose of this invention is to overcome the problem of uneven roasting of materials in the sagger in the prior art, and to provide a sagger filling device.

[0006] During production, workers discovered that shaping the material inside the sagger into a shape that is lower in the middle and higher around the edges, while ensuring that the distance between the material surface and the inner wall of the sagger is basically the same in all directions, ensures that the material inside the sagger is roasted evenly. This method allows more material to be held in a single sagger while ensuring uniform roasting, thereby increasing the amount of material roasted in a single roasting and improving industrial efficiency.

[0007] However, relying on workers to manually shape the material in the sagger into a shape that is low in the middle and high around the edges requires an additional step of manually leveling the material inside the sagger after the filling device has filled it, which is time-consuming and labor-intensive. The sagger filling device provided by this invention aims to provide a method that can automatically shape the material in the sagger into a shape that is high around the edges and low in the middle during the material filling process, thereby eliminating the need for manual material shaping and improving efficiency.

[0008] To achieve the above objectives, a first aspect of the present invention provides a sagger filling device, comprising: a lifting module, a discharging module, and a conveying module. The discharging module is disposed below the lifting module, and the conveying module is disposed below the discharging module. The discharging module includes a discharging pipe with a discharging inverted cone at its opening. A driving member is disposed outside the discharging pipe, the top of the discharging inverted cone extending into the discharging pipe. The driving member is tractably connected to the bottom of the discharging inverted cone via a connector to drive the discharging inverted cone to move up and down. The conveying module includes a sagger located below the discharging pipe to guide material from the discharging pipe into the sagger via the discharging inverted cone.

[0009] Preferably, the size of the bottom of the discharge cone is larger than the size of the bottom of the discharge pipe so that it can be driven by the drive component to block the outlet of the discharge pipe.

[0010] Preferably, the discharge module further includes a storage bin, which is located below the discharge position of the lifting module to receive the material conveyed by the lifting module, and a level gauge is installed in the storage bin.

[0011] Preferably, the discharge module further includes a discharge belt, which is located below the storage hopper, and the discharge pipe is located below the discharge belt. The discharge belt is configured to transport the material discharged from the storage hopper to the discharge pipe.

[0012] Preferably, the lifting module includes a lifting machine and a bucket, the bucket being drivably mounted on the lifting machine to be lifted to the discharge position.

[0013] Preferably, the hopper is also equipped with a valve, which opens to discharge material when the hopper is lifted to the discharge position.

[0014] Preferably, the lifting module further includes a discharge port, which is disposed on the elevator and faces the discharge module to discharge material to the discharge module.

[0015] Preferably, the parts of the lifting module and the discharge module that come into contact with the material are made of soft material.

[0016] Preferably, the conveying module further includes a conveyor belt, on which multiple saggars are placed to receive and convey the material from the discharge module.

[0017] A second aspect of the present invention provides a sagger filling method, which uses the above-described sagger filling device and includes the following steps:

[0018] S1: Load the material to be filled into the lifting module;

[0019] S2: The lifting module lifts the material to be filled and transfers it to the discharge module;

[0020] S3: Use the drive unit to drive the discharge cone to move downward to open the outlet of the discharge pipe and discharge the material;

[0021] S4: The material is fed into the sagger in the conveying module. When the feeding is finished, the drive unit drives the discharge cone to move upward to completely block the outlet of the feeding pipe and stop feeding.

[0022] The sagger filling device described in the above technical solution can fill saggers and ensure that the material filled in the saggers has a shape that is high around the edges and low in the middle. That is, the material in the saggers forms a concave shape with the lowest point at the center of the sagger and the highest point at the inner wall of the sagger. The distance from the concave surface to the inner wall surface of the saggers is equal at all points, meaning that the thickness of the material is equal everywhere. To achieve the above technical effect, this sagger filling device first lifts and transfers the material filled in the saggers to the discharge module via the lifting module, and then the discharge module fills the material into the saggers in the conveying module. The discharge module, through the discharge pipe and the discharge cone set at its opening, allows granular material to fall into the saggers through the annular opening formed by the discharge pipe outlet and the discharge cone during discharge. The size of the part of the sagger that holds the material is slightly larger than the size of the discharge pipe outlet, and the shapes are consistent, so that all the material falling from the discharge pipe can be received into the saggers. The material falling into the sagger from the annular opening accumulates in a ring shape along the inner wall of the sagger towards the center, thus forming a shape that is high around the edges and low in the center. Therefore, the sagger filling device provided by the present invention can automatically fill the sagger with material and ensure that the material has a shape that is high around the edges and low in the center, so as to ensure that the material can be roasted evenly while holding more material in the sagger.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0035] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0036] To achieve the above objectives, a first aspect of the present invention provides a sagger loading device, such as... Figure 1 and Figure 4 As shown, it includes: a lifting module 100, a discharge module 200, and a conveying module 300. The discharge module 200 is located below the lifting module 100, and the conveying module 300 is located below the discharge module 200. The discharge module 200 includes a discharge pipe 230, with a discharge cone 231 at its outlet. A drive member 232 is located outside the discharge pipe 230. The top of the discharge cone 231 extends into the discharge pipe 230, and the drive member 232 is tractably connected to the bottom of the discharge cone 231 via a connector 233 to drive the discharge cone 231 to move up and down. The conveying module 300 includes a sagger 310 located below the discharge pipe, allowing the discharge cone 231 to guide the material from the discharge pipe 230 into the sagger 310.

[0037] The sagger filling device described in the above technical solution can fill the sagger 310 and ensure that the material filled in the sagger 310 has a shape that is high around the edges and low in the middle. That is, the material in the sagger 310 presents a concave shape with the lowest point at the center of the sagger 310 and the highest point at the inner wall of the sagger 310. The distance from all points on the concave surface of the sagger 310 to the inner wall surface of the sagger 310 is equal, that is, the thickness of the material is equal everywhere. To achieve the above technical effect, the sagger filling device first lifts and transfers the material filled in the sagger 310 to the discharge module 200 through the lifting module 100, and then the discharge module 200 fills the material into the sagger 310 in the conveying module 300. The discharge module 200, via a discharge pipe 230 and a discharge cone 231 at its opening, allows granular material to fall into the sagger 310 through the annular opening formed by the discharge pipe 230 outlet and the discharge cone 231 during feeding. This annular opening is not limited to a ring formed by two concentric circles, but also includes an annular shape formed by two concentric, identical closed shapes, where one shape's area is smaller than the other's, such as an annular shape formed by two concentric rectangles, where one shape's area is smaller than the other's. The material falling into the sagger 310 from the annular opening gradually accumulates in a ring shape along the inner wall of the sagger 310 towards its center, forming a shape that is high around the edges and low in the center. Therefore, the sagger filling device provided by this invention can automatically fill the sagger 310 with material, ensuring that the material has a shape that is high around the edges and low in the center, thus allowing for more material to be placed in the sagger 310 while ensuring that the material is roasted evenly.

[0038] The lifting and lowering of the discharge cone 231 is controlled by the drive component 232, which can control the area of ​​the annular opening. The operator can control the discharge speed and discharge volume by controlling the area of ​​the annular opening to cope with the different properties exhibited by different materials when they are piled up. The discharge speed and discharge volume are adjusted so that the shape of the material piled up in the sagger 310 can meet the requirements of the next process.

[0039] Preferably, the sagger 310 is a container of any shape and size that is the same as the discharge pipe 230 and opens upwards, capable of being roasted in a roasting furnace or meeting the requirements of any other processing stage.

[0040] Preferably, such as Figure 4 As shown, the projected area of ​​the connector 233 on the annular opening is small enough to not affect the material discharge from the annular opening, ensuring that the material in the sagger 310 is piled up in a shape that is high around the edges and low in the middle.

[0041] Preferably, a guide is provided between the discharge pipe 230 and the sagger 310. The guide has the same cross-sectional shape as the cross-section at the outlet of the discharge pipe 230, but is slightly larger than the cross-section at the outlet of the discharge pipe 230, and is sufficient to cover the distance between the discharge pipe 230 and the sagger 310 to prevent material splashing. The guide can be installed below the outlet of the discharge pipe 230 or on the sagger 310. The guide ensures that the material falls completely into the sagger 310, saving material while maintaining a hygienic working environment. More preferably, the guide can be made of a transparent material, such as plastic. A guide made of transparent material allows workers to easily observe the material accumulation inside the sagger 310, thereby promptly screening out materials with unqualified accumulation shapes and preventing them from entering the next industrial process and causing waste.

[0042] Preferably, such as Figure 4 As shown, the bottom dimension of the discharge cone 231 is larger than the bottom dimension of the discharge pipe 230 so that it can be driven by the drive member 232 to block the outlet of the discharge pipe 230. In this crucible filling device, the discharge module 200, during material feeding, drives the discharge cone 231 downwards via the drive member 232 to form an annular opening, thus initiating material feeding. After the crucible 310 is filled, the drive member 232 drives the discharge cone 231 upwards to block the outlet of the discharge pipe 230, stopping material feeding. By using the discharge cone 231, which can block the bottom of the discharge pipe 230, the opening and closing of the outlet of the discharge pipe 230 can be controlled by controlling the drive member 232, thereby controlling whether material is fed, allowing this crucible filling device to fill multiple crucibles 310 at intervals.

[0043] Preferably, such as Figure 1 and Figure 3 As shown, the discharge module 200 also includes a storage bin 210, which is located below the discharge position of the lifting module 100 to receive the material conveyed by the lifting module 100. A level gauge 211 is installed in the storage bin 210. An openable and closable opening is provided at the bottom of the storage bin 210 to control whether material is being discharged. After the lifting module 100 transfers material into the storage bin 210, the level gauge 211 in the storage bin 210 reflects the amount of material in the storage bin 210, thereby confirming the required number of saggers 310 in the conveying module 300.

[0044] Preferably, such as Figure 1 and Figure 3As shown, the discharge module 200 also includes a discharge belt 220, which is located below the storage bin 210. A discharge pipe 230 is located below the discharge belt 220. The discharge belt 220 is configured to transport the material discharged from the storage bin 210 to the discharge pipe 230. The discharge belt 220 is driven by a motor or any other power source. When the discharge module 200 discharges material, the material falls from the storage bin 210 onto the discharge belt 220, which then begins to move, transporting the material to the discharge pipe 230, and finally causing the material to fall into the casket 310 through the discharge pipe 230. Since the outlet of the storage bin 210 is located on the discharge belt 220, the discharge of this sagger filling device can be controlled by starting and stopping the discharge belt 220 while the material discharge from the storage bin 210 continues. The discharge speed and discharge rate can be adjusted by setting the movement speed and time of the discharge belt 220, thereby ensuring that the amount of material filled in each sagger 310 is equal, and ensuring that the material accumulation shape in each sagger 310 is consistent by ensuring that the discharge speed is equal each time. The discharge rate and discharge speed can be stably controlled by the discharge belt 220. The discharge belt 220, in conjunction with the level gauge 211 in the storage bin 210, can further monitor the discharge rate to confirm whether the discharge rate is consistent each time.

[0045] Preferably, such as Figure 2 As shown, the discharge module 200 is surrounded by an outer shell that isolates it from the external environment. The outer shell encloses the portion of the discharge module 200 except for the material inlet on the storage bin 210 and the material outlet on the discharge pipe 230, thereby preventing external environmental factors, such as air disturbances, from affecting the discharge process, thus reducing material loss during the discharge process and ensuring consistency in the discharge amount each time.

[0046] Preferably, such as Figure 1 and Figure 2 As shown, the lifting module 100 includes a lifting machine 110 and a hopper 120. The hopper 120 is drivably mounted on the lifting machine 110 and lifted to the discharge position by the lifting machine 110. When using this sagger filling device, the operator only needs to load the material into the hopper 120, and the sagger filling device will automatically perform the remaining work.

[0047] Preferably, Figure 2As shown, a valve 121 is also provided on the hopper 120. The valve 121 opens to discharge material when the hopper 120 is lifted to the discharge position. By controlling whether the hopper 120 discharges material through the valve 121, the hopper 120 can be used to select materials of larger size and can be loaded with a volume larger than that of the storage bin 210 at one time. The material in the hopper 120 is then lowered into the storage bin 210 in multiple times, thereby reducing the number of times the hopper 120 is loaded and lifted, and improving the efficiency of this sagger filling device.

[0048] Preferably, such as Figure 1 and Figure 2 As shown, the lifting module 100 also includes a discharge port 130, which is disposed on the elevator 110 and faces the discharge module 200 to discharge material into the discharge module 200. When the hopper 120 is lifted to the discharge position, the valve 121 on the hopper 120 faces the discharge port 130, and the valve 121 opens, allowing the material to be guided to the discharge module 200 through the discharge port 130. The discharge port 130 prevents material splashing and guides all material into the discharge module 200.

[0049] Preferably, the parts of the lifting module 100, the discharging module 200, and the conveying module 300 that come into contact with the material are made of soft material. When loading materials with low structural strength that need to maintain their structure, these parts are prone to collision with the material, especially during the feeding process when the material has a certain speed, which can damage the material's structure. By using components made of soft material, such as the hopper 120, valve 121, discharge port 130, storage bin 210, discharge pipe 230, discharge cone 231, and sagger 310, the material's structure can be preserved during loading, thus ensuring the quality of the material loaded into the sagger 310.

[0050] Preferably, such as Figure 1 As shown, the conveying module 300 also includes a conveyor belt 320, on which multiple crucibles 310 are placed to receive and transport the material from the discharge module 200. Through the conveyor belt 320 and the multiple crucibles 310 placed thereon, after one crucible 310 is filled, the conveyor belt 320 can move the next crucible 310 below the discharge module 200 and begin filling again, without the need for manual placement of the crucibles 310. Through the conveyor belt 320, this crucible filling device can automatically fill multiple crucibles 310, greatly improving efficiency. Simultaneously, the conveyor belt 320 can also be connected to the next process flow, thereby quickly transferring the filled crucibles.

[0051] Preferably, each component in the lifting module 100, the discharge module 200, and the conveying module 300 is connected to the control panel. The control panel can obtain data from each component and adjust and control the operation of each component through a program. For example, the discharge amount is evaluated based on the data from the level gauge 211, thereby determining the movement time and speed of the discharge belt 220, and automatically opening the valve 121 when the reading of the level gauge 211 is lower than a certain value to transfer the material from the hopper 120 to the storage bin 210. By inputting a pre-programmed program into the control panel, this sagger filling device can automatically operate after filling the material and transport the filled sagger 310 to the next process flow.

[0052] A second aspect of the present invention provides a sagger filling method, wherein the above-described sagger filling device is used, and the sagger filling method includes the following steps:

[0053] S1: Load the material to be filled into the lifting module 100;

[0054] S2: Lifting module 100 lifts the material to be filled and transfers it to discharging module 200;

[0055] S3: The drive unit 232 drives the discharge cone 231 to move downward to open the outlet of the discharge pipe 230 and discharge the material into the sagger 310;

[0056] S4: The drive unit drives the discharge cone to move upward to completely block the outlet of the discharge pipe and stop the discharge.

[0057] Specifically, the following method is followed when filling the sagger 310:

[0058] First, the material is loaded into the hopper 120 in the lifting module 100;

[0059] The elevator 110 lifts the hopper 120 to the discharge position, and the valve 121 on the hopper 120 opens, transferring the material from the hopper 120 to the storage bin 210 in the discharge module 200. The material is then discharged from the lower outlet of the storage bin 210 onto the discharge belt 220, which operates according to a set time and speed, thereby conveying the set amount of material to the discharge pipe 230 at a set speed.

[0060] The drive unit 232 installed on the outer wall of the discharge pipe 230 drives the discharge cone 231 to move downward, so as to form an annular opening at the outlet of the discharge pipe 230. The material entering the discharge pipe 230 falls into the sagger 310 from the annular opening, so as to accumulate in the sagger 310 and form a shape that is high around the edges and low in the middle.

[0061] After the sagger 310 is filled with a single quantitative amount of material, the discharge cone 231 moves upward under the drive of the drive unit 232 and blocks the outlet of the discharge pipe 230, thereby stopping the discharge. The filled sagger 310 enters the next process flow under the drive of the conveyor belt 320, and the unfilled sagger 310 behind it is carried to directly below the discharge pipe 230 to be filled.

[0062] The above-mentioned filling steps in the cyclic section begin when the drive unit 232 moves the discharge cone 231 downwards, and end when the other unfilled sagger 310 is moved to the area directly below the discharge pipe 230, that is, from S3 to S4.

[0063] After multiple cycles, when the level gauge 211 in the storage bin 210 indicates that there is not enough material in the storage bin 210 for a single filling, the valve 121 on the hopper 120 opens and transfers the remaining material in the hopper into the storage bin 210, and the above cycle begins again.

[0064] When the material level gauge 211 in the storage bin 210 shows insufficient material, and the material level is still insufficient after opening the valve 121, the hoist 110 is operated to lower the hopper, and the material filling process is restarted in the hopper 120 according to all the above steps.

[0065] Follow the above procedure until all materials to be filled are filled; this crucible filling method is then complete.

[0066] Table 1 shows a comparison of the data of sagger 310 filled using the above-described sagger filling method and manually filled sagger 310:

[0067] Table 1

[0068]

[0069]

[0070] As shown in Table 1, this sagger filling method has the advantages of stable filling speed, uniform material distribution, and material low point position close to the center, while also greatly saving labor costs.
