Description

Technical Field

[0001] This application relates to the field of polyaluminum chloride production, and more specifically, to a polyaluminum chloride production equipment and process. Background Technology

[0002] The main raw materials containing aluminum oxide include gibbsite, bauxite, kaolin, and coal gangue. The production process can be divided into two steps: the first step is to obtain crystalline aluminum chloride, and the second step is to obtain polyaluminum chloride through pyrolysis or neutralization. Before producing crystalline aluminum chloride, gibbsite, bauxite, kaolin, and coal gangue are usually added to a mixing device in a certain proportion for stirring and crushing, ensuring the raw materials are mixed before further processing. However, the weight of gibbsite, bauxite, kaolin, and coal gangue must be manually calculated based on the material proportions and the amount added at one time, and then each material is weighed and added separately. This process has low automation, and errors are inevitable in manual calculation, weighing, and addition, resulting in insufficient energy efficiency.

[0003] There is currently no effective solution to the problems of low intelligence and insufficient energy efficiency caused by manual calculation, weighing and feeding of materials in related technologies. Summary of the Invention

[0004] The main purpose of this application is to provide a polyaluminum chloride production equipment and process to solve the problems of low level of intelligence and insufficient energy saving caused by manual calculation, weighing and feeding of materials.

[0005] To achieve the above objectives, according to one aspect of this application, a polyaluminum chloride production apparatus is provided.

[0006] The polyaluminum chloride production equipment according to this application includes: multiple storage silos for storing various materials used in the preparation of polyaluminum chloride; a pushing mechanism is provided near the bottom of each storage silo, the pushing mechanism being opposite to the discharge port of the storage silo; the discharge port of the storage silo is connected to a discharge track; the far end of the discharge track is connected to the inlet of a quantitative weighing silo; a load-bearing rail is provided at the bottom opening of the quantitative weighing silo; a sliding movable plate is provided on the load-bearing rail; a weighing device is provided on the movable plate and connected to a drive mechanism; and a stirring device is provided below the load-bearing rail; the equipment also includes: a processor, which is connected to the pushing mechanism, drive mechanism, weighing device, and stirring device. The moving part is electrically connected and is used to calculate the amount of each material to be added based on the preset material ratio and the weight of any input material. It controls the pushing mechanism in each storage bin to push each material onto the discharge track, from where it is transported to each quantitative weighing bin. When it is determined that the weight of each material measured in real time by the weighing device is the same as the amount of each material added or within the preset error range, the pushing mechanism is controlled to stop pushing, and the drive mechanism is controlled to drive the movable plate to slide away from the bottom, so that the materials in each quantitative weighing bin fall into the mixing equipment. When it is determined that the weight of each material measured in real time by the weighing device approaches zero, the movable plate is controlled to reset, and the mixing equipment is controlled to stir.

[0007] Furthermore, the load-bearing rail is inclined, and the movable plate moves a preset distance towards the upper inclined end of the load-bearing rail and then stops.

[0008] Furthermore, the load-bearing rail extends outward to form an extension rail.

[0009] Furthermore, the pushing mechanism includes: two hydraulic cylinders, a limiting block, a rotating shaft, a torsion spring, and two pushing plates. The two hydraulic cylinders are electrically connected to the processor. The limiting block is connected to the output rods of the two hydraulic cylinders. The rotating shaft is located outside the limiting block. The two pushing plates are rotatably connected to both ends of the rotating shaft by torsion springs and are located outside the limiting block.

[0010] Furthermore, the driving mechanism includes: a support plate, a drive motor, and a ball screw transmission assembly, wherein the support plate is fixed to the side of the quantitative weighing chamber, the drive motor is mounted on the support plate and connected to the ball screw transmission assembly, and the ball screw transmission assembly is connected to the movable plate.

[0011] Furthermore, a mounting base is provided on each of the opposite sides of the wall of the quantitative weighing chamber, and a striking motor is provided on the mounting base. A striking rod is connected to the output shaft of the striking motor.

[0012] Furthermore, a circular rubber ball is fitted onto the distal end of the striking rod.

[0013] Furthermore, the load-bearing rail includes: a first load-bearing component and a second load-bearing component, wherein the first load-bearing component is fixed to the inner side wall of the quantitative weighing chamber, and the second load-bearing component is fixed to the opposite side wall of the inner side wall of the quantitative weighing chamber.

[0014] Furthermore, the first and second load-bearing components are composed of an upper limit plate and a lower load-bearing plate, and a channel for sliding of the movable plate is formed between the upper limit plate and the lower load-bearing plate.

[0015] To achieve the above objectives, according to another aspect of this application, a process for producing polyaluminum chloride is provided.

[0016] The polyaluminum chloride production process according to this application includes: producing polyaluminum chloride using the aforementioned polyaluminum chloride production equipment.

[0017] This system combines polyaluminum chloride production equipment with automatic control. Based on preset material ratios and the weight of any input material, the system calculates the dosage of each material. The pushing mechanism in each storage silo pushes each material onto the discharge track, from where it is transported to the respective quantitative weighing silos. When the weight of each material measured in real-time by the weighing device matches the dosage or falls within a preset error range, the pushing mechanism stops pushing, and the drive mechanism drives the movable plate to slide away from the bottom, allowing the materials in each quantitative weighing silo to fall into the mixing equipment. This achieves the goal of automatic calculation, weighing, and precise control of material dosage, thereby improving the level of intelligence and energy efficiency. It also solves the technical problems of low intelligence and insufficient energy efficiency caused by manual calculation, weighing, and dosage of materials. Attached Figure Description

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] Example 1

[0034] Reference Figures 1-6This application relates to a polyaluminum chloride production equipment, which includes: multiple storage bins for storing various materials used in the preparation of polyaluminum chloride, such as gibbsite, bauxite, kaolin, and coal gangue; a pushing mechanism is installed near the bottom of each storage bin, and the pushing mechanism is positioned opposite the discharge port of the storage bin, thereby pushing the corresponding material in the storage bin out of the discharge port; the discharge port of the storage bin is connected to a discharge track, and the far end of the discharge track is connected to the inlet of a quantitative weighing bin, so that when the material is pushed out by the pushing mechanism, it will come from the discharge port to the discharge track, and after further pushing by the pushing mechanism, it can... Material is pushed from the inlet into the quantitative weighing hopper; a load-bearing rail is provided at the bottom opening of the quantitative weighing hopper to support a movable plate; a sliding movable plate is obstructed on the load-bearing rail, and the material can be supported or fed in by controlling the opening and closing of the movable plate; a weighing device is provided on the movable plate and connected to a drive mechanism, which can measure the weight of the material on the movable plate in real time, and drive the opening and closing of the movable plate; a stirring device is provided below the load-bearing rail to stir the material fed in; it also includes: a processor, connected to the pusher... The feeding mechanism, drive mechanism, weighing device, and driving section of the mixing equipment are electrically connected. The processor calculates the feeding amount of each material based on a preset material ratio and the weight of any input material, achieving automatic feeding amount calculation. It controls the pushing mechanism in each storage silo to push each material onto the discharge track, from where it is transported to each quantitative weighing silo. This allows for controllable feeding into the quantitative weighing silos, where the weighing device in each silo measures the weight of each material in real time. When the real-time weight of each material measured by the weighing device is the same as the feeding amount or the preset amount is reached... When the error range is reached, the control push mechanism stops pushing, and the control drive mechanism drives the movable plate to slide away from the bottom, allowing various materials in each quantitative weighing bin to fall into the mixing equipment, thereby automatically dispensing each material into the mixing equipment in proportion; when it is determined that the weight of each material measured by the weighing device in real time is close to zero, the control move plate is reset, and the mixing equipment is controlled to stir; after the dispensing is completed, the weight of each material measured by the weighing device in real time will be close to zero. At this time, the control move plate is reset to the closed state, and the mixing equipment is controlled to stir again, realizing the automation of the whole process, greatly improving the level of intelligence and energy saving.

[0035] In this embodiment, preferably, the driving mechanism includes: a support plate, a drive motor, and a ball screw transmission assembly. The support plate is fixed to the side of the quantitative weighing bin, the drive motor is mounted on the support plate and connected to the ball screw transmission assembly, and the ball screw transmission assembly is connected to a movable plate. When the movable plate needs to be opened, the drive motor drives the ball screw transmission assembly to move, and the ball screw transmission assembly drives the movable plate to slide on the support plate, thereby realizing the opening and closing control of the bottom of the quantitative weighing bin and ensuring that the material is automatically fed into the mixing equipment.

[0036] In this embodiment, preferably, a mounting base is provided on each of the opposite sides of the wall of the quantitative weighing bin, and a striking motor is provided on the mounting base. A striking rod is connected to the output shaft of the striking motor. In order to ensure that the material in the quantitative weighing bin completely enters the mixing equipment, the striking motor is started at the same time as the movable plate is opened, which drives the output shaft to rotate, thereby driving the striking rod to strike the outer wall of the quantitative weighing bin, so that the material can completely enter the mixing equipment.

[0037] In this embodiment, preferably, a round rubber ball is fitted onto the distal end of the striking rod; using a round rubber ball can reduce damage to the outer wall of the chamber, and due to its elasticity, it can be struck more effectively.

[0038] In this embodiment, preferably, the load-bearing rail includes: a first load-bearing component and a second load-bearing component. The first load-bearing component is fixed to the inner wall of the quantitative weighing chamber, and the second load-bearing component is fixed to the opposite side wall of the inner wall of the quantitative weighing chamber. Further, the first load-bearing component and the second load-bearing component are composed of an upper limit plate and a lower load-bearing plate, and a channel for sliding of the movable plate is formed between the upper limit plate and the lower load-bearing plate. The sliding channel is formed by the cooperation of the upper limit plate and the lower load-bearing plate, thereby ensuring that the movable plate can slide through it, realizing the opening and closing of the quantitative weighing chamber. The structure is simple and easy to implement.

[0039] Example 2

[0040] Reference Figure 5Based on Embodiment 1, the load-bearing rail is inclined. The movable plate moves a preset distance towards the inclined end of the load-bearing rail and then stops. When it is necessary to open the movable plate, it is driven to move a preset distance and then stop. Moving half the width of the movable plate is sufficient to ensure that it does not deviate from the rail. By using an inclined setting when the bottom of the quantitative weighing bin is not fully opened, the weight of the material can be used to ensure that the material is not stuck by the unopened part of the movable plate and can slide out from the opened opening, improving the feeding efficiency. At the same time, the inclined setting eliminates the need for an excessively long extended sliding rail, while still achieving full feeding of the material. In this embodiment, to ensure the stability of the quantitative weighing bin, support rods are installed on the outer walls of the quantitative weighing bin and the mixing equipment. Due to the inclined setting of the load-bearing rail, there is a suspended part between the quantitative weighing bin and the mixing equipment, so support rods are needed to support it and ensure the stability of the structure.

[0041] Example 3

[0042] Reference Figure 3 Based on Example 1, the load-bearing rail extends outward to form an extension rail. When in the open state, the outer movable plate will lose its support. If it is opened too much, it will derail. Therefore, an extension rail is set to prevent derailment. At the same time, the opening at the bottom of the quantitative weighing chamber can be fully opened to ensure that the material will not get stuck on the movable plate in the closed part, so as to achieve full material feeding.

[0043] Example 4

[0044] Reference Figure 2 Based on Embodiment 1, the pushing mechanism includes: two hydraulic cylinders, a limiting block, a rotating shaft, a torsion spring, and two pushing plates. The two hydraulic cylinders are electrically connected to the processor. The limiting block is connected to the output rods of the two hydraulic cylinders. The rotating shaft is located outside the limiting block. The two pushing plates are rotatably connected to both ends of the rotating shaft via torsion springs and are located outside the limiting block. When extended by the hydraulic cylinders, the pushing plates can be locked by the limiting block and rotated in the opposite direction, thereby achieving the purpose of pushing out material. When retracted by the hydraulic cylinders, since there is no... With the constraint of the limiting plate, the two push plates can rotate outward to a parallel state, effectively preventing materials from getting stuck between the inner wall and the upright push plates, thus avoiding jamming. During this process, due to the small size of the limiting plate, there is no situation where materials get stuck. In addition, near the inner wall at the proximal end, where the hydraulic cylinder output end is located, there is also a baffle cavity (not shown in the figure) that can accommodate the limiting block and push plates retracting into it. When the pushing is completed and the push plates retract into it, due to the presence of the torsion spring, the push plates will return to an upright state, allowing materials to be pushed normally.

[0045] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
