Description

Technical Field

[0001] The invention relates to the field of oyster shell processing, in particular to a uniform crushing device for oyster shell processing. Background Art

[0002] my country ranks first in the world in oyster production. Oysters are mainly eaten, and a large amount of oyster shells will be left after eating. If the remaining large amount of oyster shells are treated as garbage, it will not only occupy a large amount of land area, but also rot and stink after being piled up, polluting the environment and endangering people's health. In order to turn a large amount of oyster shell resources into treasure, it has been found that the composition of oyster shells is mainly calcium carbonate, which accounts for more than 90% of the mass of oyster shells, of which calcium accounts for more than 40%. In addition, oyster shells also contain more than 20 trace elements such as copper, iron, zinc, manganese, and strontium; at the same time, there are a large number of nano-scale micro-pores in oyster shells, which have the effect of heavy metal adsorption and can play a slow release effect when combined with other effective elements. Therefore, oyster shells are widely used in the production of soil conditioners after roasting, which are used to improve acidic soils and adsorb heavy metals in soils.

[0003] When oyster shells are processed as by-products, they need to be crushed first. For the crushing process, the existing technology mainly uses a crusher. The existing public technologies about crushers and oyster shell processing crushers are as follows:

The crusher of the present invention has better adaptability.

[0005] 2) Publication No. CN219540449U discloses a mechanism for uniformly crushing oyster shells. In this technical application, it includes a box body, a first motor is fixedly installed on one side of the box body, a first transmission rod is splined to the output end of the first motor, a first main crushing roller is fixedly installed on one end of the first transmission rod, a first connecting rod is fixedly installed on one end of the first main crushing roller, a first bearing seat is installed on one end of the first connecting rod, and a first crushing auxiliary roller is meshed on one side of the first main crushing roller. The uniformly crushing mechanism for oyster shells is arranged by the coordination of the first motor, the first transmission rod, the first main crushing roller, the first connecting rod, the first bearing seat and the first crushing auxiliary roller. When in use, the first motor external power supply drives the first transmission rod to tilt to the surface of the first main crushing roller and the first crushing auxiliary roller for initial meshing and crushing, thereby playing the role of initial crushing of the oyster shells.

[0006] 3) Publication No. CN205308416U discloses an oyster shell crushing device. In the technical application, the crushing device is a double-roll crusher, in which the distance between the two rollers of the crusher is 3 mm; a horizontal conveyor belt is provided above the feed port of the crusher, an oyster shell bin is provided above the starting point of the conveyor belt, and a gravity sensor connected to the conveyor belt motor controller is provided below the double-roll crusher; after adopting the above scheme, the utility model sets the distance between the two rollers of the crusher so that the crushed oyster shell particles are between 0-3 mm, and a conveyor belt and an oyster shell bin are provided on the crusher, and the transmission amount is controlled by the gravity sensor, so that the oyster shells entering the crusher are within a certain amount range and will not cause backlog in the double-roll crusher.

[0007] 4) Publication No. CN116786249A discloses a glass crushing device, which includes a feeding assembly, a crushing box, a primary crushing assembly, a transfer assembly, and a secondary crushing assembly. The feeding assembly includes a silo and a feeding conveyor, the crushing box has a first feed port, and one side of the crushing box forms a second discharge end; the primary crushing assembly includes a crushing hammer arranged above the first feed port, and a first driving mechanism; the transfer assembly is arranged between the crushing box and the secondary crushing assembly, and the secondary crushing assembly includes a shell, two crushing rollers, and a second driving mechanism. The present invention, by providing a hammer-type primary crushing assembly and a roller-type secondary crushing assembly, can, on the one hand, perform preliminary crushing of larger glass fragments before conveying them to the crushing rollers, thereby avoiding the occurrence of material jamming. On the other hand, the two-stage crushing makes the crushing effect better, helps to obtain slag of balanced size, and melts faster at high temperature in the kiln, which helps to improve production efficiency.

[0008] Among them, the crushers in the above-mentioned prior arts 1, 2, 3, and 4 mostly adopt a single-stage roller crushing mechanism or a multi-stage crushing mechanism. The multi-stage crushing mechanism is better than the single-stage crushing mechanism, but it requires more power sources to drive, and the main difference between the prior arts 1, 2, 3, and 4 is that, in order to facilitate loading, a loading component is arranged in front of the crusher in the prior art 4, but in actual application, due to the large number of crushing equipment in the factory, the use of a loading component + a crusher is bound to lead to increased costs, and the loading component will be idle when the crusher is in the crushing process.
