Description

A vertical fixed-moving coupling bag breaking machine

technical field

The invention relates to a bag-breaking and bottle-breaking device for garbage, in particular to a bag-breaking and bottle-breaking device that uses a rotating smooth blade and a stationary sawtooth blade to cut through bags, plastic and paper containers containing urban domestic waste, so that the internal garbage is scattered.

Background technique

With the increasing shortage of energy in the world, the output of domestic waste is still increasing rapidly. How to turn useful substances in domestic garbage into valuables has become a research hotspot today. However, in order to realize the reduction, harmlessness, and recycling of domestic waste, the first step is to separate various useful substances. Nowadays, a large amount of domestic waste is bagged, and bag breaking technology has naturally become the first problem to be solved.

At present, the commonly used bag breaking devices are widely borrowed from the fields of agriculture and mining, or directly copy the devices in foreign garbage treatment processes. The core technology tool is not only used to break the garbage bags, but also bears the gravity of the falling garbage and the rotation generated by the garbage. impact force and other effects, the damage rate is high; moreover, this kind of technology tends to over-shred the garbage, which is not conducive to the subsequent sorting process, and it is difficult to effectively separate useful substances. For example, the vertical garbage bag breaking machine (patent number: 00223653), the blade-shaped blade is directly installed on the shaft, and is directly impacted by the garbage, and the rotating chain will hammer and crush the garbage; In the cutting-based rotary crushing (bag breaking) method, inorganic brittle materials such as bricks, tiles, and glass are excessively crushed. They are mixed with organic waste with high moisture content and cannot be effectively separated, which directly affects the composting quality of subsequent rotten organic matter. Especially after waste batteries and other heavy metal-rich garbage are shredded, not only is it difficult to effectively sort, but also leachate will be precipitated, causing secondary pollution.

Contents of the invention

The object of the present invention is to provide a vertical fixed-moving coupled bag-breaking and bottle-breaking machine which can not only break bags of mixed garbage, but also break open various paper-plastic containers.

In order to achieve the above object, the technical solution adopted by the present invention is: comprising a motor, a crushing box and a base, the crushing box is provided with a feed inlet, a discharge port and an inspection window, the crushing box is fixed on the base through supports, and The cylindrical body is equipped with a main shaft coincident with the center line of the cylinder through the bearing seat and bearing fixed on the top of the cylinder and the base. The top of the main shaft is connected with the motor through a pulley and a reduction belt. Its characteristics are: inside the crushing box Consolidate 3 to 6 movable tool holders on the main shaft of each movable tool holder, and the axial direction is evenly arranged between each movable cutter holder, and the horizontal direction is arranged at an angle of 30°60°; each side of each movable knife holder is fixed with a blade in the horizontal direction There are 2 opposite moving knife blades; the center hole of the moving tool seat is set in the middle, and the main shaft is sleeved in the center hole of the moving tool seat, and is fixedly connected with the main shaft. In the crushing box, 3 to 6 groups of fixed knife seats are consolidated with the wall, and the fixed knife seats of each group are evenly arranged in the axial direction. The horizontal direction forms an included angle of 15-30°, and is staggered with the movable knife seat; each fixed knife is composed of a fixed knife holder and a fixed knife blade. There are screw holes on the top. When installing, insert the fixed knife into the crushing box, and fix the knife handle on the outer wall of the crushing box with screws. There is also a frequency converter connected to the motor on the outer wall of the crushing box. The speed of the motor can be adjusted through the frequency converter to meet the power required for crushing garbage bags of different quality and different quantities of plastic bottles inside.

The moving knife blade has a smooth edge, and the knife edge is set horizontally, and is fixedly connected with the moving knife seat by screws.

The fixed knife blade is a zigzag knife edge, and the knife edge is arranged vertically upward, and is fixedly connected with the fixed knife holder by screws.

The mutual staggering between the fixed knife seat and the movable knife seat is such that the vertical interval between each group is smaller than the size of the broken garbage bag.

The shape of the outlet of the discharge port on the crushing box is square, and the bottom forms an angle of 30-45° with the ground. The discharge is discharged from the discharge port at the lower end of the crushing box by gravity, and can directly enter the subsequent sorting system.

The beneficial effects of the present invention are:

1. Since the rotating and smooth moving knife inherently arranged horizontally on the main shaft of the present invention, and the inherently vertically arranged sawtooth-shaped fixed knife blade on the inner wall of the crushing box, the bagged garbage is subjected to the horizontal cutting force of the rotating movable knife and the joint formation of the fixed knife. Shearing force and the gravity of the garbage itself have three different effects, the bag is completely opened, and the problem of excessive crushing of garbage is better solved.

2, because the motor of the present invention is connected with the frequency converter, the rotating speed of the rotating movable knife can be adjusted by the frequency converter, so as to reach garbage bags of different strengths, paper-plastic containers, large-volume peels (such as watermelon peels), and relatively high strength. The high paper-plastic container has a good effect of breaking the bottle, so that the garbage in the container can be effectively separated; at the same time, it can ensure the integrity of the garbage in the bag.

3. Since the blade and the knife holder are connected by screws, the various impact forces during the bag breaking process are basically borne by the knife holder, which can reduce the damage rate of the blade and make it easier to replace and repair the blade.

4. The fixed knife of the present invention is inserted into the crushing box and the knife handle is left outside the box, and the knife handle is fixed on the outer wall of the crushing box by screws, so the production is easy, and the installation, maintenance and repair are convenient.
