Powder metallurgy sintering waste material dust removing device

Abstract

Disclosed is a powder metallurgy sintering waste material dust removing device. The powder metallurgy sintering waste material dust removing device comprises a negative pressure dust removal integrated system and a waste material conveying system. A small front-mounted separation tower is disposed at a waste material inlet of the negative pressure dust removal integrated system. The separation tower comprises an upper separation chamber and lower collecting buckets. Material-air separators are disposed at the bottoms of the collecting buckets. The upper separation chamber is connected with a conveying pipe in the waste material conveying system. A vertical arc-shaped baffle is disposed at a waste material inlet and in the upper separation chamber. The curved surface of the baffle faces an outlet of the conveying pipe. A channel capable of allowing waste materials to enter the waste material inlet is reserved between the top of the baffle and the upper separation chamber. By means of the powder metallurgy sintering waste material dust removing device, as primary separation is conducted before the waste materials enter the negative pressure dust removal integrated system, the dust removal pressure of the system is greatly relieved, and the operation efficiency and dust removal effect of equipment are improved; the additionally arranged small front-mounted separation tower is simple in structure and convenient to mount and maintain; the dust removal efficiency is further improved by means of the arc-shaped baffle; and the powder metallurgy sintering waste material dust removing device is convenient to manufacture and low in maintaining cost.

Description

technical field [0001] The invention belongs to environmental protection equipment, in particular to a powder metallurgy sintering waste dedusting device. Background technique [0002] In the metallurgical industry, waste disposal after powder metallurgy sintering is very tricky. These waste materials are bulk materials, which will generate a lot of dust, seriously pollute the environment, and cause serious harm to the health of operators. In order to solve this problem, some enterprises use negative pressure dust removal integrated system to collect waste materials and separate them for dust removal. Transportation and handling relieve some pollution, but due to the large dust of bulk materials, the filter bags are often blocked, which affects the dust removal efficiency and dust removal effect; therefore, the existing devices have not fundamentally solved the problem of environmental pollution. Contents of the invention [0003] The object of the present invention is t...

Problems solved by technology

These wastes are bulk materials, which will generate a lot of dust, seriously pollute the environment, and cause serious harm to the health of operators.

In order to solve this problem, some enterprises adopt the negative pressure dust removal integrated system to collect the waste materials and then carry out dust removal and separation. Transportation and handling alleviate some pollution, but due to the large dust of bulk materials, the filter bags are often blocked, which affects the dust removal efficiency and dust removal effect; therefore, the existing devices have not fundamentally solved the problem of polluting the environment
