Description

Technical Field

[0001] This utility model relates to the technical field of feeding equipment for the production of polyaluminum chloride, specifically an automated feeding device for producing calcium aluminate powder from liquid polyaluminum chloride. Background Technology

[0002] The automated feeding device for producing calcium aluminate powder from liquid polyaluminum chloride is a piece of equipment used in relevant production scenarios. With the help of an automated control system, it can accurately control the amount and speed of calcium aluminate powder being fed, and achieve linkage with other links in the production process. Its function is to replace the traditional manual feeding method and improve the feeding efficiency and accuracy.

[0003] For example, an automated feeding device for producing calcium aluminate powder from liquid polyaluminum chloride (publication number: CN219024239U) disclosed in Chinese patent literature allows for the quantitative addition of calcium aluminate powder to hydrochloric acid solution during the production of liquid polyaluminum chloride. The dosage of calcium aluminate powder added at one time can be adjusted according to the required amount of calcium aluminate powder added, making it suitable for the production process of liquid polyaluminum chloride with different yields.

[0004] However, the above quantitative feeding method usually requires fixed installation on top of the reactor. When dealing with multiple reactors, a separate feeding device needs to be equipped for each reactor, resulting in repeated equipment investment. In addition, each fixed device needs to be cleaned and maintained independently, which is time-consuming and labor-intensive. Utility Model Content

[0007] As a further embodiment of this utility model: a lid is fixedly connected to the top of the material tank, and a feed pipe is fixedly connected to the middle of the lid.

[0008] As a further embodiment of this utility model: the discharge mechanism includes a discharge valve one and a discharge pipe one, the discharge valve one being fixedly connected to one end of the bottom of the tank, and the discharge pipe one being fixedly connected to the bottom of the discharge valve one; a discharge valve two and a discharge pipe two, the discharge valve two being fixedly connected to the other end of the bottom of the tank, and the discharge pipe two being fixedly connected to the bottom of the discharge valve two, and portions of both the discharge pipe one and the discharge pipe two penetrating the sealing cover.

[0009] As a further embodiment of this utility model: the discharge docking mechanism includes an electric push rod, a connecting pipe, and a telescopic folding pipe. The electric push rod is fixedly connected to one end of the tail of the feeding shell, the connecting pipe is fixedly connected to the discharge port of the feeding shell, and the telescopic folding pipe is fixedly connected to the bottom of the connecting pipe; a connecting pipe and a connecting piece are also included. The connecting pipe is fixedly connected to the bottom of the telescopic folding pipe, and the connecting piece is fixedly connected to one end of the outer side of the connecting pipe.

[0010] As a further improvement of this utility model: the other end of the auger passes through the feeding shell and is fixedly connected to the motor output end.

[0011] As a further improvement of this utility model, the output end of the electric push rod is fixedly connected to the connecting member.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this invention, an automatic guided vehicle moves the device to a designated workstation. After feeding material into the tank through the feed pipe, it moves to the vicinity of the reactor. An electric push rod drives the connecting pipe to precisely connect with the reactor's feed inlet via a telescopic folding pipe and a connecting pipe, achieving fully automated movement without manual handling. It adapts to multiple workstation switching and can flexibly feed multiple reactors, solving the limitation of one-to-one fixed pipelines and avoiding the need for each reactor to be equipped with a separate feeding device, resulting in repeated equipment investment and requiring independent cleaning and maintenance, which is time-consuming and labor-intensive. When the discharge valve one or discharge valve two is opened, the material falls into the feeding shell through the corresponding discharge pipe and is conveyed to the discharge docking mechanism by the auger. The dual discharge valves correspond to discharge pipes of different diameters, allowing one to be used and one to be on standby. When the pipeline is blocked or needs cleaning, the other line can be switched to continue production, reducing downtime risks and improving equipment utilization. Attached Figure Description

[0024] Reference Figure 1 , Figure 2 and Figure 4 The discharge mechanism 5 includes a discharge valve 501 and a discharge pipe 502. The discharge valve 501 is fixedly connected to one end of the bottom of the material tank 4, and the discharge pipe 502 is fixedly connected to the bottom of the discharge valve 501.

[0025] The discharge valve 2 503 and the discharge pipe 2 504 are fixedly connected to the other end of the bottom of the material tank 4, and the discharge pipe 2 504 is fixedly connected to the bottom of the discharge valve 2 503. The discharge pipe 1 502 and the discharge pipe 2 504 both penetrate the sealing cover 9.

[0026] Reference Figure 1 , Figure 2 and Figure 5 The discharge docking mechanism 6 includes an electric push rod 601, a connecting pipe 602, and a telescopic folding pipe 603. The electric push rod 601 is fixedly connected to one end of the tail of the feeding shell 3, the connecting pipe 602 is fixedly connected to the discharge port of the feeding shell 3, and the telescopic folding pipe 603 is fixedly connected to the bottom of the connecting pipe 602.

The output end of the electric push rod 601 is fixedly connected to the connector 605.

[0028] The working principle of this utility model is as follows: An automatic guide cart 2 moves the support frame 1 and the entire device to a designated workstation. Calcium aluminate powder is loaded into the material tank 4 through the feed pipe 11 in the middle of the tank cover 10, facilitating subsequent feeding. Then, the automatic guide cart 2 moves the support frame 1 and the entire device near the reactor. An electric push rod 601 pushes the connecting piece 605, causing the connecting pipe 604 to adjust its position via the telescopic folding pipe 603 and the connecting pipe 602, ensuring precise alignment between the connecting pipe 604 and the reactor inlet. This allows for the quantitative feeding of subsequent materials into the reactor via the connecting pipe 604. This achieves fully automated movement throughout the process, eliminating the need for manual handling and adapting to the multi-station switching requirements of the production line. The entire device can flexibly feed multiple reactors. This method overcomes the limitations of fixed pipelines for one-to-one feeding, avoiding the need for separate feeding devices for each reactor, which leads to repeated equipment investment and requires independent cleaning and maintenance, resulting in time and labor costs. Based on process requirements, the discharge valve 501 or discharge valve 503 at the bottom of the material tank 4 is opened. The material falls into the feeding housing 3 through discharge pipe 502 or discharge pipe 504. The motor 8 is started to drive the auger 7 to rotate, conveying the material along the feeding housing 3 to the tail end, where it is finally discharged by the discharge docking mechanism 6. Discharge valve 501 and discharge valve 503 can correspond to discharge pipes 502 and 504 of different diameters, respectively. This method allows for one-to-one backup; when one discharge pipe is blocked or needs cleaning, the other can be switched to continue production, reducing the risk of downtime and improving equipment utilization.
