Description

Technical Field

[0001] The utility model relates to the technical field of automation equipment, in particular to an automatic electrolyte feeding machine. Background Art

[0002] Molten salt electrolysis of rare earth oxides is an important rare earth element extraction technology. It uses the solubility and electrochemical properties of rare earth oxides at high temperatures to extract rare earth elements from oxides by electrolysis. This technology has the advantages of high efficiency, environmental protection, and energy saving, and has become one of the main methods for extracting rare earth elements.

[0003] In existing molten salt electrolysis equipment, the electrolyte needs to be transported by an automatic electrolyte feeder. However, the existing automatic electrolyte feeder generally controls the electrolyte discharge through a draw-out valve structure. The draw-out valve structure generally sets a baffle at the bottom of the silo and controls the electrolyte discharge by utilizing the expansion and contraction of the baffle, which makes it impossible to accurately control the electrolyte discharge amount.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] It should be understood that although the terms upper, middle, lower, top, end, etc. appear in this article to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish elements from each other for easy understanding, and are not used to define any direction or order limitation.

[0031] like Figure 1-7 As shown, an automatic electrolyte feeding machine includes a mounting bracket 3, a quantitative feeding structure 1 is arranged in sequence from top to bottom along the mounting bracket 3, and an automatic discharging structure 2 for receiving the electrolyte output by the quantitative feeding structure 1.

[0032] Specifically, the quantitative feeding structure 1 includes a feed bin 101 for storing electrolytes, and a screw assembly 102 arranged at the bottom of the feed bin 101. The screw assembly 102 includes a feed channel 103 arranged at the bottom of the feed bin 101, a feed screw 104 rotated in the feed channel 103, and a feed unit 105 for driving the feed screw 104 to rotate.

[0033] The automatic discharging structure 2 includes a receiving bin 201 for receiving electrolytes, a discharging channel 202 connected to the receiving bin 201, a discharging screw 203 arranged in the discharging channel 202, and a discharging unit 204 for driving the discharging screw 203 to rotate. A material control component 301 for controlling the material dropping is arranged between the feeding channel 103 and the receiving bin 201.

[0034] During the entire electrolyte discharge process, by storing a large amount of electrolyte in the feed bin 101, the electrolyte can enter the feed channel 103 from the bottom of the feed bin 101, and as the feeding unit 105 drives the feeding screw 104 to rotate, a certain amount of electrolyte is transported to the receiving bin 201, and then the receiving bin 201 is used to transfer the electrolyte to the discharge channel 202, and finally the electrolyte is discharged through the discharge screw 203, and a material control component 301 is arranged between the feed channel 103 and the receiving bin 201, and the material control component 301 can prevent the material from falling into the receiving bin 201 after the feeding screw 104 finishes its action.

The feed pipe 402 is made of flexible material, and when cleaning is required, the feed pipe 402 can be directly taken out from the receiving bin 201, thereby making it easier for subsequent maintenance.

[0040] like Figure 3 , Figure 7 As shown, a further explanation of the automatic discharging structure 2 in this embodiment is provided, wherein the discharging screw 203 is a rectangular spring, and the elasticity of the rectangular spring is utilized to avoid the metal particles in the electrolyte, thereby avoiding material jamming.

[0041] Furthermore, a weighing unit 401 is provided at the bottom of the automatic discharging structure 2, and the weighing unit 401 can accurately detect the weight of the electrolyte in the receiving bin 201, thereby ensuring the accuracy of the discharged electrolyte weight.

[0042] In addition, a second vibration unit 404 is provided on the receiving bin 201 , and the second vibration unit 404 can act on the receiving bin 201 to increase the drop speed of the electrolyte inside the receiving bin 201 and avoid material jamming.

[0043] like Figure 1 As shown, as a further explanation of the implementation method of the feeding bin in this embodiment, a first vibration unit 403 is provided on the feeding bin 101, and the first vibration unit 403 can act on the feeding bin 101 to increase the electrolyte drop speed inside it to avoid material jamming.
