Description

Technical Field

[0001] The utility model relates to the technical field of solid waste recycling automated processing equipment, in particular to a refractory brick crushing waste material classification device. Background Art

[0002] In steel smelting production enterprises, refractory brick materials are needed in many places, and the amount of use is very large. In addition, the amount of refractory brick waste generated by its long-term production will be even greater. These refractory brick wastes are often mixed with some metal materials. Generally, steel production enterprises directly pile up or bury the wastes, and will not set up special treatment departments to reprocess them. However, these refractory brick wastes can be recycled as solid waste, so companies related to refractory brick solid waste treatment were born. However, the waste treatment of many solid waste treatment companies is relatively simple and crude. That is, the refractory brick waste is directly crushed first, and then the crushed refractory brick materials are directly used for brick making operations, without fine grading and screening. In this way, it cannot reflect its higher added value. Therefore, it is necessary to grade refractory brick materials. Summary of the invention

[0003] The purpose of the present invention is to provide a refractory brick crushing waste grading device in view of the above situation. The waste grading device of the present invention is a grading device specially designed for the treatment of refractory brick waste.

DETAILED DESCRIPTION

[0013] The following will be combined with the drawings of the utility model to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the utility model.

[0014] In the description of the present utility model, it should be noted that the terms "upper", "lower", "inside", "outside" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of describing the present utility model or simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed or operated in a specific direction. Therefore, they cannot be understood as limitations on the present utility model.

[0015] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0016] See also Figures 1 to 3 The utility model is a refractory brick crushing waste grading equipment, which is sequentially provided with a first belt conveyor 1, a vibrating screen 4 and a second belt conveyor 7. An inclined screen 3 is provided in front of the feeding port of the vibrating screen, and the inclined screen is placed below the feeding port of the first belt conveyor and connected therewith. The screen surface of the vibrating screen is also inclined, and the discharge port of the vibrating screen is placed above the inlet end of the second belt conveyor. The mesh diameter of the inclined screen is smaller than the mesh diameter of the vibrating screen; a discharge hopper 2 is arranged on the shell of the vibrating screen just below the inclined screen, and a collecting box A8 is arranged below the discharge hopper; a collecting box B5 is provided below the vibrating screen.

[0017] Furthermore, in the present embodiment, the first belt conveyor and the second belt conveyor are both arranged to tilt upward, and the inclined screen and the screen surface of the vibrating screen are both arranged to tilt downward, and the inclined screen vibrates together with the vibrating screen.

[0018] Furthermore, in this embodiment, a material-blocking plate 6 is provided at the feed port end of the second belt conveyor, and the material-blocking plate is placed above the conveying belt of the second belt conveyor and close to the belt, and the material-blocking plate is arranged below the discharge port end of the vibrating screen.

[0019] Furthermore, the material retaining plate in this embodiment has a front baffle 11 and side panels 10 on both sides, and the side panels on both sides are supported and fixed on the bracket of the second belt conveyor. A notch is left at the lower end of the front baffle and is set close to the conveying belt surface of the second belt conveyor.

[0020] The utility model is used in conjunction with a crusher. After being crushed by the crusher, the refractory brick waste first reaches the first belt conveyor for upward transportation. When it reaches the end, it first falls onto the inclined screen. The inclined screen will vibrate and screen together with the vibrating screen. The finest material will pass through the first screening and go down from the discharge hopper to be collected by the collecting box A. The crushed waste with slightly larger particles will enter the vibrating screen. After further vibration screening by the vibrating screen, the second-stage refractory brick waste will be screened out and enter the collecting box B below for collection again. The remaining refractory brick waste with the largest particles will fall onto the second belt conveyor and continue to be transported forward to form the third-stage waste.

[0021] After the above-mentioned screening, the crushed refractory brick waste is divided into several different waste grades, and then can be made into waste recycled refractory bricks of different fine grades. The strength and performance of bricks made of different fine grades are different (the performance of bricks is not discussed here), thereby achieving different levels of utilization value.

[0022] In the utility model, a material blocking plate is also arranged at the feeding port end of the second belt conveyor, so that the broken materials conveyed to the second belt conveyor are not easy to fall off.

[0023] The utility model equipment is a grading equipment designed for the recycling and reuse of refractory brick waste. After the refractory brick waste is crushed by a crusher, the particle sizes of the crushed materials are different. At this time, after the grading treatment of the utility model, the crushed materials can be graded into different particle sizes. The crushed materials of different particle sizes can be reused to make new bricks of different grades, thus generating higher economic value. Therefore, the utility model also has higher practical promotion value.
