Description

Technical Field

[0001] This application relates to the technical field of electrolytic manganese dioxide equipment, and particularly relates to a manganese dioxide blending tank. Background Art

[0002] After electrolysis and stripping of electrolytic manganese dioxide, manganese dioxide blocks are obtained, and then after powder making, powdered manganese dioxide is obtained. During electrolysis, the component contents of the manganese dioxide precipitated in different electrolytic cells or different electrode plates of the same electrolytic cell will have some differences. In order to avoid excessive component differences in the same batch of manganese dioxide powder when leaving the factory, before packaging, the manganese dioxide powder is usually sent into a blending tank. After different batches of manganese dioxide powder are evenly mixed with each other by different blowing methods, they are then sent into a packaging tank for packaging to ensure that the component contents of the manganese dioxide powder are the same when leaving the factory. In order to improve the blending speed, some blending devices have been designed. For example, a Chinese patent with the application number 202210795650.4 discloses a gravity blending bin for powder materials, including a bin body and a blending component arranged inside the bin body. The upper part of the blending component is connected to a vibrator through a top connection structure, the lower part of the blending component is connected to a blending chamber through a bottom connection structure, a connecting flange is arranged between the blending chamber and the bin body, and an annular channel is formed at the position above the connecting flange between the bin body and the blending component. When this device is applied to the blending of manganese dioxide, due to the mutual extrusion between the manganese dioxide powders and poor fluidity, even though the device is provided with a vibrator on the blending pipe, it still cannot ensure that the manganese dioxide powder spontaneously flows into the blending pipe, reducing the blending speed. Therefore, a manganese dioxide blending tank is needed, which drives the entire blending pipe to move up and down through a telescopic rod, forcing the manganese dioxide powder into the blending pipe, avoiding the situation of manganese dioxide powder jamming, and improving the blending speed. Summary of the Utility Model

[0003] In order to solve the above problems, this application proposes a manganese dioxide blending tank, which drives the entire blending pipe to move up and down through a telescopic rod, forcing the manganese dioxide powder into the blending pipe, avoiding the situation of manganese dioxide powder jamming, and improving the blending speed.

[0020] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present application are only used to explain the relative position relationship and movement conditions between components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0022] In addition, the descriptions involving "first", "second", etc. in the present application are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0023] As Figures 1 to 2 shown, an embodiment of the present invention provides a manganese dioxide blending tank, including: a blending tank body 1, a partition 5 is provided at the lower part of the blending tank body 1, and a dust collector 6 is provided at the upper part of the blending tank body 1; a blending pipe 2, the blending pipe 2 is vertically installed in the blending tank body 1, the lower end of the blending pipe 2 passes through the partition 5 and communicates with the lower cavity of the blending tank body 1, the upper end of the blending pipe 2 is closed, and the upper end of the blending pipe 2 passes through the upper part of the blending tank body 1 upward; a feeding tank 3, the upper end of the feeding tank 3 is communicated with the lower part of the blending tank body 1, and the feeding tank 3 is communicated with the dust collector 6 through a feeding pipe; wherein, a bracket 7 is provided at the upper part of the blending tank body 1, and the upper end of the blending pipe 2 is connected to the bracket 7 through a telescopic rod 11.

[0024] After manganese dioxide is ground, it is sent into the dust collector 6 through high-pressure air flow. After being separated by the dust collector 6, the manganese dioxide powder falls into the blending tank body 1, while the high-pressure air flow is discharged into the atmosphere through the dust collector 6. After a certain amount of manganese dioxide powder is added to the blending tank body 1, high-pressure air is passed through the lower part of the feeding tank 3. Under the action of the air flow, the manganese dioxide powder in the feeding tank 3 flows along the feeding pipe into the dust collector 6. After separation, the manganese dioxide powder in the feeding tank 3 falls into the upper part of the blending tank body 1. At the same time, the telescopic rod 11 drives the blending pipe 2 to move up and down in the blending tank body 1. When the blending pipe 2 moves upward, it drives the feeding cover 8 to move upward, thereby pushing the manganese dioxide powder into the feeding port, so that the manganese dioxide powder at different heights falls into the lower part of the blending tank body 1. When the blending pipe 2 moves downward, the manganese dioxide powder loses support and is driven by the blending pipe 2 to fill the space after the manganese dioxide powder slides down. Thus, driven by the telescopic rod 11, the manganese dioxide powder quickly falls into the blending pipe 2. And multiple blending pipes 2 can be arranged on the blending tank body 1. Through the mutual cooperation of the blending pipes 2, the falling speed of the manganese dioxide powder is increased, thereby increasing the mixing speed. After the manganese dioxide powder at different heights falls into the lower part of the blending tank body 1, it is mixed and then falls into the feeding tank 3, and then is sent back to the upper part of the blending tank body 1 through the feeding tank 3. After repeating the cycle many times, the manganese dioxide powder in the blending tank body 1 is evenly mixed. After the mixing is completed, the manganese dioxide powder is sent into the packaging tank through the feeding tank 3 and can be shipped out after being bagged.

[0025] Preferably, a plurality of feeding ports are provided on the outer periphery of the blending pipe 2, and the feeding ports are staggered along the axial direction of the blending pipe 2. And a feeding cover 8 is provided outside the feeding port. The feeding cover 8 covers the outside of the feeding port, and the opening of the feeding cover 8 faces upward. The plurality of feeding ports can introduce the manganese dioxide powder at different heights into the lower part of the blending tank body 1, thereby accelerating the mixing speed between the manganese dioxide powders at different heights. When the feeding cover 8 moves upward, it can press the manganese dioxide powder so that it enters the feeding cover 8 and then falls into the feeding port. When the feeding cover 8 moves downward, it can stir the manganese dioxide powder to make the manganese dioxide powder collapse and fill the cavity, thereby preventing the manganese dioxide powder from getting stuck in the feeding port and accelerating the falling speed of the manganese dioxide powder.

[0026] In a specific embodiment, a plurality of air pressure holes 9 are provided in the upper part of the blending pipe 2. When the manganese dioxide powder falls, the air pressure balance in the upper part of the blending pipe 2 can be ensured through the air pressure holes 9, so as to facilitate the smooth falling of the manganese dioxide powder into the cavity in the lower part of the blending tank body 1.

[0027] Preferably, as Figure 2As shown, the upper end of the mixing pipe 2 is connected to the upper part of the mixing tank body 1 through a telescopic sleeve. The telescopic sleeve is provided with multiple wavy folds. The telescopic sleeve can prevent manganese dioxide powder from floating out through the gap at the connection, and the wavy folds can expand and contract to facilitate the telescopic sleeve to move up and down with the upper end of the mixing pipe 2.

[0028] In a preferred embodiment, an isolation valve 10 is provided between the feeding tank 3 and the mixing tank body 1. After closing the isolation valve 10, the feeding tank 3 can be kept airtight. After introducing high-pressure air, the high-pressure air can be discharged from the feeding pipe.

[0029] In a preferred embodiment, one side of the lower part of the feeding tank 3 is connected to a high-pressure gas source, and the other side of the lower part of the feeding tank 3 is connected to the feeding pipe. After passing through high-pressure air, the air flow will spontaneously flow through the feeding pipe to the upper part of the mixing tank body 1 with lower pressure, so as to realize the transportation of manganese dioxide powder through the air flow. A three-way switching valve is provided on the feeding pipe. The three-way switching valve is also connected to the packaging tank through the feeding pipe. The flow direction of the air flow can be controlled through the three-way switching valve, and after mixing is completed, the manganese dioxide powder can be conveniently fed into the packaging tank.

[0030] In a preferred embodiment, the middle part of the partition plate 5 is recessed downward, and a through hole is provided in the middle part of the partition plate 5. After mixing is completed, without the mixing pipe 2 moving up and down, at this time, the powder in the mixing tank body 1 mainly falls into the feeding tank 3 through the through hole in the middle part of the partition plate 5.

[0031] In a preferred embodiment, the mixing pipe 2 is a square pipe, and the square pipe can prevent the mixing pipe 2 from rotating axially, so that it can only slide axially.

[0032] Preferably, the telescopic rod 11 adopts a commercially available electric telescopic rod or a hydraulic telescopic rod. The electric telescopic rod or the hydraulic telescopic rod has a large thrust and can meet the resistance required for the up and down movement of the mixing pipe 2.

[0033] Certainly, the present application can also have other various implementation manners. Based on this implementation manner, other implementation manners obtained by those of ordinary skill in the art without any creative labor belong to the scope protected by the present application.
