Description

Parallel multi-channel transmission device and multi-channel large-capacity intelligent external circulation system

technical field

The invention relates to the technical field of lithium battery electrode material production, in particular to a parallel multi-channel transmission device and a multi-channel large-capacity intelligent external circulation system.

Background technique

Lithium battery electrode materials are prepared by sintering powder in the kiln. The outer circulation line system cooperates with the kiln to form a cycle, and is connected with the upper mixing system and the lower finished material crushing and conveying system. Among them , The kiln and the external circulation line system form an automatic circulation system for the sintering process of lithium battery materials.

With the rapid growth of the application of lithium batteries in electric vehicles, 3C and other fields, the output of lithium batteries in my country has increased year by year, and higher requirements have been placed on the production capacity and quality of lithium battery electrode materials. According to the statistics of GGII (High-tech Industrial Research Institute), China’s lithium battery shipments in 2021 will be 327GWh, and the shipments of lithium battery cathode materials will be 1.13 million tons. The volume exceeds 2 million tons. The industry's demand for a complete set of equipment has reached hundreds of sets, and the market demand has reached hundreds of millions of yuan. With the increase in demand for new energy batteries, there is an annual growth of more than 80%, and the market size reaches billions of yuan. At present, most of the production capacity of a single powder processing equipment in China is concentrated in the processing capacity of 90-150 bowls/hour. As shown in Figure 1(a), the existing external circulation line system includes a single-channel transmission line 1', a treatment furnace 2, a furnace-in transfer machine 3, a furnace-out transfer machine 4, a single-station transfer machine 17', a feeding The transmission line 5 and the discharge transmission line 6, and the single-channel transmission line 1' are sequentially provided with a single-channel container stacking device 7', a single-channel cleaning device 13', and a single-channel cutting device 16', single-channel quantitative feeding device 14', single-channel powder leveling device 15', single-channel cleaning device 13', single-channel residual powder detection device 10', elevator 8, single-channel powder pouring device 9 ' and single channel cleaning device 13'. The material transportation of the external circulation system adopts single-line transportation, which cannot meet the growing capacity demand of the new energy industry. Even if the two lines are conveyed in parallel (as shown in Figure 1(b)), the doubled cost will occupy too much plant area, and it is very expensive. Use less. The rapid development of the industry has put forward higher requirements for supporting equipment. The external circulation line system is a very important part of the production process of positive and negative materials. The number of single machines is large, and the automation control logic is relatively complicated, which has a decisive impact on production capacity. At present, the performance of most of the equipment cannot meet the rapidly expanding production capacity demand, and the quantity and quality are at a low level. Therefore, the industry urgently needs to develop a complete set of multi-channel large-capacity intelligent external circulation system to improve the processing quality of powder materials, increase production capacity, and improve the level of intelligent control.

Considering that the production capacity can be increased without increasing the excessive cost and the occupied area of the workshop, the parallel connection of equipment has become the main design idea, but there are too many difficulties in realizing the parallel connection of the entire outer track:

1. Reduce the footprint: In a limited space, two devices must be connected in parallel, and many mechanisms in the device interfere with each other and affect the movement;

2. If the conventional blocking method is adopted for blocking and positioning between multiple containers, it is bound to double the width of the entire conveying mechanism;

3. The same shaft carries parallel containers, the span of the shaft is too large and it is easy to bend;

4. Parallel conveying is difficult to realize the complete synchronous operation of two containers, and there may be front and rear misalignment of the containers. The conventional accumulation function is placed at the end of the shaft, which can only control whether the entire shaft rotates, and cannot separately accumulate the two parallel containers; When the front and back of the container are misaligned, if they are accumulated, the subsequent container may not be conveyed in place, and the follow-up action cannot be carried out normally; if it is not accumulated, the first container will rub against the conveying roller, causing wear to the container. This is not allowed.
