Problems solved by technology

[0003] However, it is obvious that during the operation of the casting production line, if the control is not proper, it is easy to produce bad problems such as trachoma and subcutaneous pores; for example: when the product is normally produced, the sand is processed and returned to the sand system, and the old sand is not uniform when the belt is conveying the old sand. When water is added, the moisture content of the old sand will be uneven, which will eventually lead to unstable production of the product, resulting in defects such as trachoma and subcutaneous pores.
It will eventually lead to a high scrap rate, which greatly increases the cost of the product

Embodiment

[0060] An environment-friendly sand treatment, storage and transportation system made of diesel engine body cylinder head castings for vehicles, including: large-capacity and high-efficiency bucket elevator, fine hexagonal screen, belt conveyor, belt feeder, and suspended belt permanent magnetic separator , Disc feeder, screw feeder, vibrating conveyor, powder boiling low-pressure pneumatic conveying device, dust removal system.

[0061] 1. Large capacity bucket elevator

[0062] The large-capacity and high-efficiency bucket elevator is composed of a head unit, a tail unit, an intermediate shell, a high-strength adhesive tape and a hopper. It adopts a multi-row hopper arrangement, and burns and coats industrial mirror enamel in the hopper, and mainly loads at the bottom. Picking is an auxiliary loading material, and after being transported to the top, it is centrifugally unloaded, and the tail is tensioned by a heavy hammer.

Abstract

The invention discloses an environment-friendly sand treatment storage and transportation system for automotive diesel engine engine-body cylinder head castings. The environment-friendly sand treatment storage and transportation system for automotive diesel engine engine-body cylinder head casting comprises a large capacity and high-efficiency bucket type elevator, a fine hexagonal sieve, a belt type conveyor, a packaging tape feeding machine, a suspended belt type permanent magnet separator, a disc feeding machine, a screw feeding machine, a vibration conveyor, a powder boiling type low-pressure pneumatic conveyor and a dust removal system. The environment-friendly sand treatment storage and transportation system for the automotive diesel engine engine-body cylinder head castings meets the national environmental protection and dust noise emission standards. The dust emission concentration is not more than 50 mg / m<3>, and the noise emission of a draught fan is less than or equal to 85db (A).

Description

technical field [0001] The invention belongs to the field of sand treatment, and in particular relates to a sand treatment, storage and transportation system for manufacturing an environment-friendly vehicle diesel engine block cylinder head casting. Background technique [0002] As we all know, casting is a method of casting liquid metal into a casting cavity adapted to the shape of the part, and then cooling and solidifying it to obtain a part or blank. Casting is a common process method for producing castings, and its application is very wide. Steel, iron and most non-ferrous alloy castings can be obtained by casting. [0003] However, it is obvious that during the operation of the casting production line, if the control is not proper, it is easy to produce bad problems such as trachoma and subcutaneous pores; for example: when the product is normally produced, the sand is processed and returned to the sand system, and the old sand is not uniform when the belt is conveyi...
