Abstract
The utility model relates to a squirrel-cage type briquette crusher which comprises an inner hitting wheel and an outer hitting wheel which are connected to a support by shafts. A plurality of hitting bars are longitudinally arranged on the inner hitting wheel and the outer hitting wheel, and wear-resistant blocks are fixed on the hitting contact surfaces of the hitting bars. The use of the squirrel-cage type briquette crusher shows that the wear-resistant degree of the hitting bars is enhanced, and the service life is prolonged by more than three times.
Description
Technical field
The utility model relates to a kind of reducing mechanism, specifically relates to a kind of moulded coal pulverizer.
Background technology
In type coal gasification technique, the moulded coal pulverizer of moulded coal workshop section is the special equipment of moulded coal processing, its operation principle is to rotate by empty set two squirrel-cage striking wheel high-speed reverse together, the raw coal that enters in the cage is broken step by step, pulverizer rod coal grain continuous and that the coal grain occurs tangentially to collide bulk of beating on the mouse cage in the process of running up is broken for the coal grain that meets granularity requirements, the round steel of the 45# of use steel matter is made pulverizer and is played rod more in the market, because of 45# steel itself not wear-resisting, cause pulverizer mouse cage quick abrasion, the cycle of operation is short, only 3-5 days, if mouse cage integral body is made of high-abrasive material, greatly prolonged its service life, but manufacturing cost is higher.
Summary of the invention
For above-mentioned situation, the purpose of this utility model provides a kind of squirrel-cage moulded coal pulverizer, makes simply, strengthens rub proofness, increases the service life.
A kind of squirrel-cage moulded coal of the utility model pulverizer, the interior striking wheel and the outer striking wheel that are connected on the bearing by axle consist of, and on interior striking wheel and outer striking wheel many impacting rods are set vertically, are fixed with wear-resistant block at the contact-making surface that impacts of described impacting rod.
Preferably, described wear-resistant block built-up welding impacting on the contact-making surface at impacting rod.
Use squirrel-cage moulded coal pulverizer of the present utility model, manufacturing cost is lower, has strengthened to beat excellent rub proofness, prolongs its service life more than 3 times.
Description of drawings
Fig. 1 is a kind of squirrel-cage moulded coal of the utility model pulverizer front view;
Fig. 2 is a kind of squirrel-cage moulded coal of the utility model pulverizer side view.
The specific embodiment
As shown in Figure 1 and Figure 2, a kind of squirrel-cage moulded coal pulverizer, the interior striking wheel 2 and the outer striking wheel 1 that are connected on the bearing by axle consist of, and on interior striking wheel 2 and outer striking wheel 1 many impacting rods 3 are set vertically, impact at described impacting rod 3 that built-up welding has wear-resistant block 4 on the contact-making surface.
Claims (2)
1. squirrel-cage moulded coal pulverizer, the interior striking wheel and the outer striking wheel that are connected on the bearing by axle consist of, and on interior striking wheel and outer striking wheel many impacting rods are set vertically, it is characterized in that being fixed with wear-resistant block at the contact-making surface that impacts of described impacting rod.
2. squirrel-cage moulded coal pulverizer according to claim 1 is characterized in that described wear-resistant block built-up welding impacting on the contact-making surface at impacting rod.
