Description

Technical Field

[0001] The invention relates to the technical field of rock mining, and in particular to a crushing device for crushing quartzite. Background Art

[0002] Quartzite is a metamorphic rock mainly composed of quartz, with a quartz content of more than 85%. It is formed by the metamorphism of quartz sandstone and siliceous rock. The main mineral of quartzite is quartz (SiO 2 ), and may also contain mica minerals and other minerals such as hematite and goethite. The presence of these minerals will affect the color and physical properties of quartzite; there are two main ways for the formation of quartzite: one is formed by regional metamorphism and recrystallization of quartz sandstone or other siliceous rocks; the other is formed by thermal contact metamorphism of siliceous rocks near magma. Both methods give quartzite unique physical and chemical properties, and special quartzite crushing equipment is required in the crushing of quartzite.

[0003] The previous crushing device for crushing quartzite has the following disadvantages: it cannot make the shock wave move in the ideal direction, and gradually weaken the violent energy to make the process more gentle, which is conducive to crushing small rocks, and has poor safety. The friction between the crushing device and the quartzite is large, causing metal impurity contamination in the rock body, and the structure is not convenient for disassembly, replacement and transportation. Therefore, those skilled in the art provide a crushing device for crushing quartzite to solve the problems raised in the above background technology. Summary of the invention

[0004] The main purpose of the present invention is to provide a crushing device for crushing quartzite to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0007] Buffer springs are installed on both sides of the top of the support and positioning sleeve through positioning plates and screws, and the buffer springs are located on the outside of the reaction tube. A waterproof gasket is arranged on the top of the support and positioning sleeve, and a lower top cover is sleeved on the bottom end of the cylindrical sleeve shell, and the bottom of the lower top cover is sleeved in the connecting ring, and the bottom of the connecting ring is connected and welded with a support cover shell, and a guide sleeve rod is welded to the bottom of the support cover shell, and the breaking rod passes through the support cover shell and the guide sleeve rod respectively, and the guide sleeve rod is exposed at the bottom end of the breaking rod and is not sleeved with a high-voltage insulating sleeve.

[0008] As a further solution of the present invention: a positioning guide sleeve is installed at the bottom of the cylindrical shell and in the lower top cover through a mounting hole, and the breaking rod passes through the positioning guide sleeve. A positioning guide sleeve is installed in the lower top cover through a mounting hole to guide the breaking rod, thereby improving stability during vibration crushing.

[0009] As a further solution of the present invention: the high-voltage electrode is fixed to the top of the high-voltage electrode sleeve by locking with a fixing nut.

[0010] As a further solution of the present invention: the bottom of the high-voltage electrode is provided with a positive and negative high-voltage electrode, and the positive and negative high-voltage electrode are located in the reaction tube.

[0011] As a further solution of the present invention: locking nuts are installed on both sides of the connecting ring through screw holes.

[0012] As a further solution of the present invention: the crushing rod is specifically a titanium alloy rod and is in the shape of a solid cylinder, the support cover is specifically in the shape of a hollow truncated cone, the titanium alloy rod and is in the shape of a solid cylinder for transmitting shock waves, the support cover is specifically in the shape of a hollow truncated cone, which is used to fix 2 and provide the device with stronger mechanical properties.

[0013] As a further solution of the present invention: the high-voltage insulating sleeve is specifically made of tubular nylon material, which is used to wrap the breaking rod to prevent leakage and buffering. The high-voltage insulating sleeve is specifically made of tubular nylon material, which is used to wrap the breaking rod to prevent leakage and buffering. It is wear-resistant, corrosion-resistant, high-temperature-resistant and durable.

[0014] As a further solution of the present invention: small holes are opened at equal distances through the surface of the guide sleeve rod for fixing the high-voltage insulating sleeve and further buffering.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. Connect the high-voltage electrode to the power supply and turn on the power. At this time, a shock wave is generated in the reaction tube and spreads to the surroundings. At this time, the buffer spring deforms after receiving the shock wave, converting kinetic energy into elastic potential energy, thereby offsetting the lateral shock wave and ensuring that the shock wave propagates downward. When the shock wave reaches the upper end of the crushing rod, due to the conductivity of the metal, the shock wave will be transmitted along the crushing rod. During the downward propagation, the lateral shock wave is gradually absorbed by the high-voltage insulating sleeve, the guide sleeve rod and the support cover to ensure that the shock wave propagates downward until it reaches the quartzite. When the quartzite is broken by the shock wave, its internal mechanical energy is instantly released to form a reverse shock wave. Since the distance between the crushing rod and the quartzite is extremely short, the reverse shock wave will be transmitted in the reverse direction along the crushing rod. At this time, due to the excellent geometric shape of the support cover, part of the reverse shock wave can be resisted, and the remaining reverse shock wave continues to be transmitted upward. When it contacts the buffer spring, the buffer spring deforms again, converting kinetic energy into elastic potential energy, thereby offsetting the reverse shock wave and making the device more stable.

[0017] 2. The crushing device used for crushing quartzite has multiple layers of buffer devices along the levels to make the shock wave move in the ideal direction and gradually weaken the violent energy, making the process gentler, which is conducive to crushing small rocks and improves safety. It greatly reduces the friction between the crushing device and quartzite, reduces metal impurity pollution and extends the service life of the crushing device. The structure is mostly assembled, which is easy to disassemble, replace and transport. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The high-voltage electrode 12 is locked and fixed to the top of the high-voltage electrode sleeve 11 by a fixing nut 13 ; the fixing nut 13 facilitates locking and fixing the high-voltage electrode 12 to the top of the high-voltage electrode sleeve 11 .

[0030] Among them, the high-voltage electrode 12 is provided with a positive and negative high-voltage electrode 14 at the bottom and the positive and negative high-voltage electrode 14 are located in the reaction tube 15; after the high-voltage electrode 12 is connected to a power source and energized, a shock wave is generated in the reaction tube 15 and spreads to the surroundings.
