Description

Crushing hammer head of mill

Technical Field

The utility model belongs to the technical field of mill equipment, concretely relates to broken tup of mill.

Background

Depending on the grinding media and the grinding stock, mills can be classified into ball mills, column mills, rod mills, tube mills, autogenous mills, rotary-mortar roll mills, vertical mills, multi-layer vertical mills, disc mills, DMC mills, etc. The vertical mill is ideal equipment for the milling industry integrating crushing, drying, milling and grading conveying, can be widely applied to industries such as cement, electric power, metallurgy, chemical industry, non-metal ores and the like, and is used for milling blocky, granular and powdery raw materials into required powdery materials.

The working principle of the vertical flour mill is that the high-speed rotation of the millstone drives the crushing hammer heads on the circumferential edge of the top of the millstone to rotate at a high speed, the grinding impact of the gear ring and the crushing hammer heads rotating at a high speed and the mutual impact between materials are utilized to grind the materials into powder, and the faster the rotating speed of the millstone is, the smaller the particle size of the ground powder is. In the grinding process, no matter the material directly impacts the crushing hammer head at a high speed or impacts the crushing hammer head after rebounding through the gear ring under the action of the gravity of the material, the material impacts the root and the lower part of the crushing hammer head, so that the root and the lower part of the crushing hammer head are extremely easy to wear. And among the prior art, generally adopt pin location, the mode of hexagon socket head cap screw embedding locking to fix the broken tup on the mill, connect firmly inadequately, after long-term the use, the wearing and tearing of broken tup root and lower part can further aggravate its and mill junction not hard up, weaken the grinding striking effect between broken tup and the ring gear greatly, are unfavorable for the crushing and grinding to the material. Under the action of the grinding disc rotating at a high speed, the loosening of the crushing hammer head and the abrasion of the root of the crushing hammer head easily cause the crushing hammer head to break, damage other parts and cause production safety accidents, are not beneficial to the efficient and safe production of the pulverizer, and need to be improved.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model aims to provide a broken tup of mill, fix a position through the constant head tank, with in tup body embedding constant head tank, can increase tup body bottom and mill area of contact, alleviate the wearing and tearing that tup body bottom received, reduce tup body installation focus simultaneously to adopt multiunit bolted connection, to the promotion of shearing force resistance in the operation, can improve the firm in connection nature between broken tup and the mill greatly, in order to solve current broken tup bottom easy wear, connect insecure, the lower scheduling problem of security.

In order to achieve the above object, the utility model adopts the following technical scheme: the utility model provides a broken tup of mill, includes mill and a plurality of tup body, it has a plurality of constant head tanks to be the circumference distribution on the outer circumference of mill upper surface, be equipped with a plurality of screw thread through-holes between constant head tank bottom and the mill lower surface, in tup body and constant head tank one-to-one and the corresponding constant head tank of embedding, the tup body all through with the bolt and the constant head tank threaded connection of screw thread through-hole looks adaptation, just the bolt bottom all stretches out the mill lower surface and overlaps and be equipped with lock nut.

Preferably, the constant head tank is circumference equidistant equipartition, the equidistant equipartition of screw thread through-hole.

Preferably, the bottom of the hammer head body is matched with the positioning groove.

Preferably, the hammer head body is provided with a threaded connecting hole matched with the threaded through hole corresponding to the threaded through hole.

Preferably, the center of the grinding disc is vertical and is fixedly connected with a rotating shaft, and a gear ring is arranged on the periphery of the grinding disc.

The utility model has the advantages that: the utility model relates to a rationally, simple structure replaces original pin through the constant head tank to fix a position, with tup body embedding constant head tank in, can alleviate the wearing and tearing that tup body bottom received, can increase tup body bottom and mill assembly area of contact again, improves its life, strengthens the steadiness of being connected of broken tup and mill. Simultaneously, reduce tup body installation focus simultaneously to adopt multiunit bolted connection and replace the mode of original hexagon socket head cap screw embedding locking with the fixed mode of lock nut locking, promote the shearing force resistance in the operation, can improve the firm in connection nature between broken tup and the mill greatly, guarantee that the safety of crocus, stable, high-efficient go on.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments:

as shown in fig. 1 to 3, a grinding machine breaking hammer comprises a grinding disc 2 and a plurality of hammer bodies 1. A plurality of positioning grooves 6 are circumferentially distributed on the outer circumference of the upper surface of the grinding disc 2 and used for positioning and installing the hammer head body 1. A plurality of thread through holes 8 are arranged between the bottom of the positioning groove 6 and the lower surface of the grinding disc 2 and used for connecting and fixing the hammer head body 1 and the grinding disc 2. In tup body 1 and the corresponding constant head tank 6 of constant head tank 6 one-to-one and embedding, fix a position through constant head tank 6 replacement pin 10 among the prior art (as shown in fig. 4) to with during tup body 1 embedding constant head tank 6, can alleviate the wearing and tearing that the bottom of tup body 1 received, can increase the assembly area of contact of tup body 1 bottom and mill 2 again, improve its life, strengthen broken tup and the steadiness of being connected of mill 2.
