Description

Technical Field

[0001] This application relates to the field of sodium carbonate preparation, and in particular to a vacuum feeding device for ultrafine sodium carbonate. Background Technology

[0002] Sodium-ion batteries are a new type of battery based on sodium carbonate. When using sodium carbonate in sodium-ion batteries, it needs to be prepared as ultrafine sodium carbonate. In the preparation process of ultrafine sodium carbonate, a vacuum feeder is typically used to feed the sodium carbonate.

[0003] The existing vacuum feeder includes a feeding cylinder, a vacuum generator located inside the feeding cylinder, and an inlet and an outlet on the feeding cylinder. A feed hose is connected to the inlet. During feeding, the feed hose is inserted into the hopper, and then the vacuum generator is turned on to create a vacuum inside the feeding cylinder. Sodium carbonate is drawn into the feeding cylinder by the vacuum suction. Then, the vacuum generator is turned off, and the sodium carbonate in the feeding cylinder is output from the outlet.

[0004] However, during the feeding process, the feed hose is prone to shaking under the vacuum suction, which prevents the feed hose from smoothly adsorbing sodium carbonate, greatly reducing the feeding efficiency of sodium carbonate; at the same time, the continuously shaking feed hose will squeeze sodium carbonate out of the hopper, causing the sodium carbonate to become contaminated and unusable. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this application provides a vacuum feeding device for ultrafine sodium carbonate that can prevent the feeding hose from shaking during feeding.

[0006] The vacuum feeding device provided in this application adopts the following technical solution:

[0007] A vacuum feeding device for ultrafine sodium carbonate includes a feeding cylinder, an inlet and an outlet on the feeding cylinder, and a vacuum generator on the feeding cylinder. The inlet is connected to a feeding hose, which is located to the side of the inlet and hangs downward. A positioning rod is provided on the feeding cylinder, which is located below the inlet. A positioning seat is provided at the end of the positioning rod, and the feeding hose is housed in the positioning seat.

[0008] By adopting the above technical solution, the feed hose can be housed in the positioning seat, which effectively avoids the feed hose from shaking during feeding. This not only improves the feeding efficiency of sodium carbonate, but also prevents sodium carbonate from being squeezed out of the hopper by the feed hose.

[0009] In one specific implementation, the feeding cylinder is installed vertically, and a mounting base is provided on the side of the feeding cylinder. The positioning rod is provided on the mounting base and extends in the horizontal direction.

[0010] By adopting the above technical solution, the installation strength of the positioning rod can be effectively improved.

[0011] In one specific implementation, the positioning rod is movably configured in a horizontal direction, and the vacuum feeding device further includes a first driving member for driving the positioning rod to move.

[0012] By adopting the above technical solution, the feed hose can change its horizontal position under the action of the positioning rod and adsorb sodium carbonate at different positions in the hopper, effectively eliminating dead zones in the feed and improving the feed efficiency.

[0013] In one specific implementation, the mounting base has a groove that extends vertically, and the positioning rod is movably inserted into the groove in the vertical direction. The vacuum feeding device also includes a second driving member for driving the positioning rod to move.

[0014] By adopting the above technical solution, the feed hose can change its vertical position under the action of the positioning rod and adsorb sodium carbonate at different heights in the hopper, effectively eliminating the dead angle of feed in the hopper and improving the feed efficiency.

[0015] In one specific implementation, the positioning rod is provided with a slider, the slider is slidably connected to the slide groove, and the two sides of the groove opening are provided with abutment parts for resisting the slider.

[0016] By adopting the above technical solution, it is possible to avoid the positioning rod from detaching from the mounting base and affecting its positioning effect on the feed hose.

[0017] In one specific implementation, the positioning seat has a positioning groove, and the feed hose is accommodated in the positioning groove.

[0018] By adopting the above technical solution, the positioning groove can limit the feed hose and prevent the feed hose from falling off the positioning seat.

[0019] In one specific implementation, the wall of the positioning groove is a rough surface.

[0020] By adopting the above technical solution, the rough groove wall can increase the friction between the feed hose and the positioning groove, and prevent the feed hose from being excessively twisted in the positioning groove and deformed.

[0021] In one specific implementation, the diameter of the opening of the positioning groove is smaller than the outer diameter of the feed hose.

[0022] By adopting the above technical solution, the feeding hose can be prevented from detaching from the positioning groove, thus improving the positioning groove's limiting effect on the feeding hose.

[0023] In one specific implementation, the vacuum feeding device further includes a base, the feeding cylinder is supported on the base, the discharge port is opened at the bottom of the feeding cylinder, the discharge port is connected to a discharge pipe, and a valve is provided on the discharge pipe.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] The feed hose can be housed in the positioning seat, which effectively prevents the feed hose from shaking during feeding. This not only improves the feeding efficiency of sodium carbonate, but also prevents sodium carbonate from being squeezed out of the hopper by the feed hose. Attached Figure Description

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] See Figure 1 As shown, a vacuum feeding device for ultrafine sodium carbonate is illustrated, comprising a feeding cylinder 1, an inlet 2 and an outlet 3 formed on the feeding cylinder 1, and a vacuum generator 4 disposed on the feeding cylinder 1. The feeding cylinder 1 is vertically mounted; the vacuum generator 4 is located at the top of the inlet 2, with its output end located inside the feeding cylinder 1 and capable of performing a vacuum operation on the feeding cylinder 1; the inlet 2 is located on the upper part of the side wall of the feeding cylinder 1, and the outlet 3 is located at the bottom end of the feeding cylinder 1.

[0032] The feed inlet 2 is connected to a feed hose 5, which is located to the side of the feed inlet 2 and hangs down. The feed cylinder 1 is provided with a positioning rod 6, which is located below the feed inlet 2. The end of the positioning rod 6 is provided with a positioning seat 7, and the feed hose 5 is housed in the positioning seat 7.

[0033] During feeding, the feed hose 5 is inserted into the hopper 18, and the positioning seat 7 is aligned with the feed hose 5. Then, the vacuum generator 4 is turned on, creating a vacuum inside the feeding cylinder 1. Sodium carbonate in the hopper 18 is drawn into the feeding cylinder 1 under negative pressure adsorption. The vacuum generator 4 is then turned off, and the sodium carbonate is discharged from the outlet 3 at the bottom of the feeding cylinder 1. Throughout the feeding process, the feed hose 5 remains contained within the positioning seat 7, effectively preventing vibration during feeding. This not only improves the feeding efficiency of sodium carbonate but also prevents sodium carbonate from being squeezed out of the hopper 18 by the feed hose 5.

[0034] In this embodiment, a mounting base 8 is provided on the side of the feeding cylinder 1, and a positioning rod 6 is provided on the mounting base 8 and extends in the horizontal direction.

[0035] The positioning rod 6 is movable in both the horizontal and vertical directions. The vacuum feeding device also includes a first driving component 9 for driving the positioning rod 6 to move horizontally and a second driving component 11 for driving the positioning rod 6 to move vertically. The first driving component 9 is a cylinder, and the second driving component 11 is a combination of a motor and a lead screw. In this way, the feed hose 5 can change its horizontal and vertical positions under the action of the positioning rod 6, allowing the feed hose 5 to adsorb sodium carbonate at different positions and heights within the hopper 18, effectively eliminating dead zones in the feed within the hopper 18 and improving feeding efficiency.

[0036] In this embodiment, the mounting base 8 has a sliding groove 10 extending vertically. A slider 12 is mounted on the positioning rod 6 and is slidably connected to the sliding groove 10. Abutment portions 13 for blocking the slider 12 are provided on both sides of the groove opening of the sliding groove 10. A lead screw constituting the second driving member 11 is rotatably inserted into the sliding groove and threadedly connected to the slider 10. Driven by a motor, the lead screw can rotate, causing the slider 10 to slide vertically.

[0037] In this embodiment, a positioning groove 14 is provided on the positioning seat 7, and the feed hose 5 is accommodated in the positioning groove 14. The groove wall of the positioning groove 14 is rough. The positioning groove 14 can limit the position of the feed hose 5 and prevent the feed hose 5 from falling off the positioning seat 7; while the rough groove wall can increase the friction between the feed hose 5 and the positioning groove 14, and prevent the feed hose 5 from being excessively twisted in the positioning groove 14 and deformed.

[0038] In this embodiment, the diameter of the opening of the positioning groove 14 is smaller than the outer diameter of the feed hose 5. The smaller diameter can prevent the feed hose 5 from detaching from the positioning groove 14, thereby improving the limiting effect of the positioning groove 14 on the feed hose 5.

[0039] In this embodiment, the vacuum feeding device also includes a base 15, on which the feeding cylinder 1 is supported. The discharge port 3 is located at the bottom of the feeding cylinder 1, and a discharge pipe 16 is connected to the discharge port 3. A valve 17 is installed on the discharge pipe 16. During discharge, the collection box is placed below the discharge pipe 16 beforehand. Then, the vacuum generator 4 is turned off and the valve 17 is opened. Sodium carbonate can fall from the discharge pipe 16 into the collection box under the action of gravity.

[0040] The implementation principle of a vacuum feeding device according to an embodiment of this application is as follows:

[0041] During feeding, the feed hose 5 is inserted into the hopper 18, and the positioning groove 14 is aligned with the feed hose 5. Then, the vacuum generator 4 is turned on, and a vacuum state is formed in the feeding cylinder 1. The sodium carbonate in the hopper 18 is drawn into the feeding cylinder 1 under the action of negative pressure adsorption. Then, the vacuum generator 4 is turned off and the valve 17 is opened, and the sodium carbonate is output from the outlet 3 at the bottom of the feeding cylinder 1.

[0042] 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.
