Description

Technical Field

[0001] This utility model relates to the field of sludge treatment technology, and in particular to a pre-drying and crushing device for treating high-viscosity sludge. Background Technology

[0002] Sludge treatment is a process of reducing, stabilizing, and rendering harmless sludge by means of concentration, conditioning, dewatering, stabilization, drying, or incineration.

[0003] Early sludge pre-drying technology primarily relied on natural sun-drying, spreading the sludge thinly on a drying site for direct sunlight or using indirect sunlight through greenhouses. This method required a long drying period, was heavily influenced by climate, and had inconsistent pre-drying results. In contrast, the pre-drying process utilizes crushing to mechanically break down the sludge's aggregate structure and cell walls, releasing bound water and facilitating evaporation, thus shortening the drying time. Furthermore, the crushed sludge particles are smaller, significantly increasing their specific surface area, which accelerates water evaporation and improves the drying rate.

[0004] Existing technologies often use shear crushers to crush high-viscosity sludge. However, the crushing teeth on the crushing rollers inside the crusher are fixed and cannot be adjusted according to actual needs (e.g., if the sludge contains large stones, the position of the crushing teeth on the two crushing rollers needs to be adjusted to enlarge the drop channel). Furthermore, shear crushers typically use conveyors to transport the sludge during feeding, and due to the high viscosity of the sludge, incomplete discharge is common. Therefore, this invention proposes a pre-drying and crushing device for processing high-viscosity sludge to address the shortcomings of existing technologies. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this utility model is to provide a pre-drying and crushing device for processing high-viscosity sludge. The device consists of a first crushing roller and a second crushing roller, each composed of a roller and an adjustable crushing tooth assembly. By moving the connecting assembly, multiple toothed rods in the same group can be moved. When multiple sets of toothed rods are installed on the first and second crushing rollers and their positions can be adjusted as needed, the material discharge channel between the first and second crushing rollers can be changed, thereby improving the flexibility of the crusher.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A pre-drying and crushing device for processing high-viscosity sludge includes a crusher shell, a sludge feeding conveyor belt, a first crushing roller, and a second crushing roller. A feed inlet is provided on the upper side of one side of the crusher shell. The output end of the sludge feeding conveyor belt extends from the feed inlet into the interior of the crusher shell. A scraping assembly is provided below the sludge feeding conveyor belt inside the crusher shell, and the scraping assembly contacts the bottom of the sludge feeding conveyor belt. The crusher housing contains a first crushing roller and a second crushing roller, which are rotatably mounted inside the lower part of the housing. The first and second crushing rollers are driven by a geared motor and move in opposite directions. The first and second crushing rollers have the same structure, both including a roller and an adjustable crushing tooth assembly. The adjustable crushing tooth assembly is located inside the roller and includes a bracket, a connecting component, and a toothed rod. The bracket is fixedly installed inside the roller, and the outer wall of the roller has through grooves. Multiple through grooves are arranged in groups, and a toothed rod is located in each through groove. One end of the toothed rod is detachably installed to the connecting bracket via the connecting component. The toothed rod of the first crushing roller meshes with the toothed rod of the second crushing roller.

[0007] A further improvement is that the scraping assembly includes a scraper and a fixing plate. The scraper has a triangular cross-section and a fixing plate is provided on one side of the lower end of the scraper. The fixing plate is installed to the side wall of the crusher casing by bolts.

[0008] A further improvement is that a guide platform is provided at the bottom of the fixed plate, and the guide platform is installed to the side wall of the crusher casing by bolts.

[0009] A further improvement is that the connecting assembly includes a connecting plate and an adjusting rod. The roller is provided with a connecting plate, and the number of connecting plates is adapted to the number of through slots. The bracket is provided with an adjusting slot adapted to the position of the connecting plate. The connecting plate is provided with an adjusting rod, and one end of the adjusting rod is movably disposed in the adjusting slot.

[0010] A further improvement is that: the adjusting rod is provided with adjusting holes, and there are multiple adjusting holes; the bracket is provided with adjusting bolts, and the adjusting bolts are inserted into the adjusting holes and locked to the bracket by nuts.

[0011] A further improvement is that: a first crushing plate and a second crushing plate are provided on the inner wall of the crusher casing, the positions of the first crushing plate and the second crushing plate are respectively adapted to the first crushing roller and the second crushing roller, the crushing teeth on the first crushing plate mesh with the toothed rod of the first crushing roller, and the crushing teeth on the second crushing plate mesh with the toothed rod of the second crushing roller.

[0012] The beneficial effects of this utility model are as follows: This utility model sets the first crushing roller and the second crushing roller to be composed of rollers and adjustable crushing tooth assemblies. By moving the connecting assembly, multiple toothed rods in the same group can be driven to move. When the first crushing roller and the second crushing roller are equipped with multiple sets of toothed rods and their positions can be adjusted as needed, the material discharge channel between the first crushing roller and the second crushing roller can be changed, thereby improving the flexibility of the crusher. This invention improves feeding efficiency by installing a scraping assembly below the sludge feeding conveyor belt inside the crusher casing. The scraper of the scraping assembly can slide the sludge adhering to the sludge feeding conveyor belt off and guide it through the guide platform to the space between the first crushing roller and the second crushing roller for crushing.
