Description

Technical Field

[0001] This utility model relates to the field of crushing equipment technology, and in particular to a high-efficiency crushing device for the production of special sand. Background Technology

[0002] With the rapid development of urbanization, the demand for building materials is increasing. Special sands widely used in construction and other fields mainly include: quartz sand, heavy calcium sand, silica sand, garnet sand, etc. Due to their unique physical and chemical properties, they are used in different fields. Different special sands have different characteristics and applications.

[0003] However, many special sands have characteristics such as high hardness and high density. Due to the presence of hard-to-crush parts in the raw materials or their impurities, or due to unsuitable spacing between crushing rollers in the equipment, some incompletely crushed parts are left during crushing, requiring subsequent screening. However, subsequent screening not only adds an extra step but also fails to reflect the crushing status of the raw materials in a timely manner, increasing the intensity of manual labor. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency crushing device for the production of special sand, which achieves screening while crushing, and the screening is smoother, reducing problems such as clogging, and making it easier to observe the crushing of raw materials, thus reducing labor intensity.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A high-efficiency crushing device for special sand production includes a crusher body, a crushing component inside the crusher body, which crushes the special sand raw material. The crusher body also includes a screening component and an outlet component located below the crushing component. The outlet component includes a fully crushed inlet and a difficult-to-crush inlet in the middle. There are two difficult-to-crush inlets located on both sides of the fully crushed inlet. The screening component includes an arc-shaped filter screen and a scraper. The fully crushed inlet is located below the arc-shaped filter screen. The scraper slides back and forth along the upper side of the arc-shaped filter screen to sweep the difficult-to-crush special sand raw material into the difficult-to-crush inlets on both sides.

[0007] By adopting the above technical solution, the crushing component crushes the special sand raw material. After crushing, the material falls into the arc-shaped filter screen. The crushed material that has been screened enters the central crushing inlet. As the scraper slides back and forth along the side of the arc-shaped filter screen, it further screens the crushed material through the arc-shaped filter screen, making the screening thorough. Finally, it continuously sweeps the difficult-to-crush special sand raw material into the difficult-to-crush inlets on both sides, realizing crushing and screening at the same time. The screening effect is good and the problems of clogging are reduced.

[0008] Furthermore, the crusher body is connected to a swing drive component, which drives the scraper to swing back and forth on the upper side of the arc-shaped filter screen.

[0009] By adopting the above technical solution, the oscillating drive component drives the scraper to oscillate back and forth on the upper side of the arc-shaped filter screen, thereby achieving thorough screening and sweeping the difficult-to-crush special sand raw material into the difficult-to-crush openings on both sides.

[0010] Furthermore, the swing drive includes a connecting arm and a swing cylinder for driving the connecting arm to swing. There are two connecting arms, which are rotatably connected to the crusher body respectively, and the scraper is connected between the free ends of the two connecting arms.

[0011] By adopting the above technical solution, the swing cylinder drives the connecting arm to swing, and the scraper is connected between the free ends of the two connecting arms, and swings back and forth to achieve screening.

[0012] Furthermore, the arc-shaped filter screen is provided with guide filters on both sides with downward-sloping outer ends, and the guide filters point to the corresponding difficult-to-break opening positions.

[0013] By adopting the above technical solution, the guide screen is directed to the corresponding difficult-to-crush opening position, so that the two sides of the arc-shaped filter screen can still screen while guiding the crushed material that cannot be screened into the difficult-to-crush opening.

[0014] Furthermore, the arc-shaped filter screen and the guide filter screen have a circular arc transition, and two placement rods are provided inside the crusher body, with the circular arc transition position of the arc-shaped filter screen abutting against the corresponding placement rod.

[0015] By adopting the above technical solution, it is convenient to manufacture the arc-shaped filter screen and the guide filter screen as a single unit, and to connect them to the crusher body, thereby improving structural stability.

[0016] Furthermore, the crusher body includes a maintenance plate on one side, which is detachably connected to the crusher body, and the placement rod and the arc-shaped filter screen are detachably connected to the inside of the maintenance plate.

[0017] By adopting the above technical solution, the arc-shaped filter screen can be easily disassembled and replaced via the inspection plate to maintain the crushing effect of the crushing device itself and facilitate maintenance operations.

[0018] Furthermore, a positioning hole is provided at the end of the placement rod, and a positioning block that matches the positioning hole is provided on the inner side of the crusher body opposite to the inspection plate.

[0019] By adopting the above technical solution, when the inspection plate is disassembled and reinstalled, the stability after installation is improved by the docking of the positioning block and the positioning hole, so that the arc-shaped filter screen can be stably connected to the crusher body.

[0020] Furthermore, the crushing assembly includes at least two crushing rollers positioned directly above the arc-shaped filter screen.

[0021] By adopting the above technical solution, the opposite rotation between the two crushing rollers realizes the crushing of special sand raw materials, and the raw materials fall onto the arc-shaped filter screen under their own weight to achieve screening.

[0022] In summary, this utility model has the following beneficial effects:

[0023] The two crushing rollers rotate in opposite directions and crush the special sand raw material. After crushing, the crushed material falls into the arc-shaped filter screen. The crushed material that has passed through the screen enters the crushing port in the middle. As the scraper slides back and forth along the side of the arc-shaped filter screen, it further screens the crushed material through the arc-shaped filter screen, making the screening thorough. Finally, it continuously sweeps the difficult-to-crush special sand raw material into the difficult-to-crush ports on both sides, realizing crushing and screening at the same time, with good screening effect and reducing clogging and other problems.

[0024] The inspection plate is detachably connected to the crusher body to facilitate the disassembly and replacement of the arc-shaped filter screen, maintaining the crushing effect of the crushing device itself and facilitating maintenance operations. When the inspection plate is disassembled and reinstalled, the positioning block and positioning hole are aligned to improve the stability after installation, allowing the arc-shaped filter screen to be stably connected to the crusher body.
