Description

Technical Field

[0001] This invention relates to the field of waste recycling technology, and in particular to a horizontal waste pressing machine and pressing method using a gas-liquid combination in an industrial dust collector. Background Technology

[0002] With the development of industry, the requirements for dust removal equipment are getting higher and higher. Industrial dust collectors need to have waste conveying and pressing functions. For example, in the new energy battery manufacturing industry, in addition to the requirement of having the function of waste gas filtration, it is also necessary to collect and compress the solid edge waste generated by the electrode laser forming machine during die cutting. The performance of the waste conveying and pressing device affects the dust removal efficiency of the entire dust collector.

[0003] In the production process of new energy lithium batteries, processes such as rolling, slitting, and electrode tab die-cutting generate electrode scraps. The methods for handling these scraps all have certain shortcomings, and there are two common methods:

[0004] (1) The waste material is transported to a transfer tank by the negative pressure generated by the blower, where it is stored and collected, or it is coarsely compacted by a simple compaction device in the transfer tank (compression is usually carried out by a cylinder, with the compression direction vertically downward). This method can centrally process the waste material, reduce its volume, and effectively alleviate the problem of limited storage space inside the production equipment. However, because the strip-shaped waste material is relatively loose and has strong resilience, the compression ratio of this method is low, and frequent collection is still required.

[0005] (2) A screw compressor is used to collect scrap materials. The scrap materials are transported to the scrap hopper by the negative pressure generated by the blower. There is a screen at the air outlet at the top of the scrap hopper to filter the scrap materials. There is a gate valve storage bin at the bottom of the scrap hopper. The scrap materials settle at the bottom of the scrap hopper under the action of gravity. When the gate valve is opened, the scrap materials fall into the storage bin and then into the screw feed bin below, and are continuously fed into the material bag in front.

[0006] However, this method requires manual cleaning of the metal foil waste from the material bag at regular intervals, which not only increases the labor intensity of operators and reduces work efficiency, but also easily leads to lightweight metal foil waste bands getting tangled in the screw shaft, requiring machine shutdown for processing, seriously affecting lithium battery production efficiency. The screw shaft is installed with a single-sided cantilever, which, under repeated uneven circumferential loads during operation, is prone to shaft bending and runout, collision and impact with the waste chamber wall, and generates significant noise. Summary of the Invention

[0007] This invention provides a horizontal waste material pressing machine and method using a combined gas-liquid process for industrial dust collectors. It overcomes the shortcomings and deficiencies of existing technologies, such as low efficiency in processing copper and aluminum foil waste, high labor costs, and problems with material jamming and clogging.

[0008] This invention optimizes the automation level of the production line by using high-load automatic compression and linkage pushing functions for metal foil waste, thereby increasing the throughput and space utilization of metal foil waste processing. The linkage pushing function automatically pushes the compressed waste blocks out of the designated collection device, eliminating the need for traditional manual timed material removal.

[0009] This invention is achieved through the following technical solution:

[0021] The linkage base plate 35 is connected to the lower side of the waste push plate 34;

[0022] The lower guide rail slider 37 is connected to both sides of the linkage base plate 35;

[0023] The spring block mechanism 36 is located on the outside of the front side plate of the pressure chamber and is connected to the pressure mold 303 located on the inside of the front side plate of the pressure chamber.

[0030] Caster 42 is connected to the frame of the lower base 43;

[0031] The waste block guide groove 41 is connected to one side of the upper base plate 44.

[0032] The feed funnel 1 is a quadrilateral opening with a draft angle in the vertical direction.

[0034] The pressing method of the gas-liquid combined horizontal waste pressing machine for industrial dust collectors of the present invention is as follows:

[0035] Step 1: Waste metal foil enters the pressing chamber from the feeding funnel 1;

[0036] Step 2: The pneumatic-hydraulic cylinder 2 is driven by the PLC control system 5 to push hydraulic oil into the pneumatic-hydraulic booster cylinder 31. At this time, the waste pusher plate 34 pushes and compresses the fluffy metal foil waste in the opposite direction towards the pressing mold 303 on the inner side of the front plate of the pressing chamber.

[0037] Step 3: The metal foil waste is compressed into a slanted waste block at die 303;

[0038] Step 4: When the waste pusher plate 34 returns to its original position, the spring block mechanism 36 pushes the waste block at the die over. In the next pressing cycle, the linkage base plate 35 pushes the overturned waste block out of the pressing chamber.

[0039] An opening is provided on the linkage base plate 35. When the waste block falls into the opening, the linkage base plate 35 pushes the overturned waste block out of the pressing chamber. The opening is rectangular, and there is an approximately 60° opening on the rear side of the opening to form a blade, which is used to cut the uncompressed metal foil waste strip in the pressing chamber when the compressed waste block is pushed out in linkage.

[0083] Step 2: The pneumatic-hydraulic cylinder 2 is driven by the PLC control system 5 to push hydraulic oil into the pneumatic-hydraulic booster cylinder 31. At this time, the waste pusher plate 34 pushes and compresses the fluffy metal foil waste in the opposite direction towards the pressing mold 303 on the inner side of the front plate of the pressing chamber.

[0084] Step 3: The metal foil waste is compressed into a slanted waste block at die 303;

[0085] Step 4: When the waste pusher plate 34 returns to its original position, the spring block mechanism 36 pushes the waste block at the die over. In the next pressing cycle, the linkage base plate 35 pushes the overturned waste block out of the pressing chamber.

[0086] An opening is provided on the linkage base plate 35. When the waste block falls into the opening, the linkage base plate 35 pushes the overturned waste block out of the pressing chamber.
