Abstract

The utility model relates to an arch combined depression bar lining board of cylindrical grinding machine, which is composed of single block lining plates, depression bars, screw bolts, etc. The utility model is characterized in that each single block lining plate is not provided with a hole which is penetrated through a screw, the inner surface of an outer shell of the grinding machine is padded with a layer of soft plastic plate when the utility model is assembled, the lining plates and the depression bars are tightly arranged on the soft plastic plate, namely a depression bar is arranged in the interval of a few lining plates, the depression bars are fixed on the outer shell of the grinding machine by the screw bolts, and the close contact of the smooth sides of the lining plates and the depression bars realize fixation between the lining plates and the fixation between the lining plates and the depression bars. The utility model has the advantages of simple structure, easy design, easy manufacture, easy installation, flexible and convenient portage. The utility model can be made in friable materials with a low price, which is convenient to reduce costs.

Description

Arch combination press strip liner plate

The utility model relates to the liner plate that grinds machinery that industrial departments such as a kind of mining industry, building materials, chemical industry and electric power use, the liner plate of the cylindrical shape grater of particularly a kind of nonferrous mine diameter below 2M.

Now, the cylindrical shape grater that each industrial department uses is (as rod mill, ball mill etc.) employed liner plate, mostly be the punching liner plate that high manganese steel material is made, it connects with the grater shell, generally all adopt bolting, the weak point of this liner plate is the restriction that is subjected to bolt, liner plate is generally all bigger, make and install all difficult, in less (particularly diameter below the 2M) grater of diameter, potassium steel can not get good work hardening, wear-resisting performance is not in full use, under the wet-milling condition, about general 1 year service life, the slurry that mixes with water of grinding charge material often spills from the slit in joint bolt hole in addition, and the appearance of grater and workplace are polluted.

The purpose of this utility model is the above-mentioned weak point that overcomes prior art, and a kind of structure and simplicity of design are provided, and is convenient to make and install, and service time is length and the novel lining plate that does not pollute grater itself and workplace.

The purpose of this utility model is achieved in that the utility model is by the monolithic liner plate, press strip, soft plastic board and the parts such as bolt that press strip is fixed on the grater shell combine, the monolithic liner plate be entad with the square of flat side down, the surface is a waveform, flat shape or other shapes, press strip is that length and liner plate length match, thick (wide) spends the rectangular of less and flat side down, there is the hole of passing screw at its center, combination of the present utility model is on the inner surface of cylindrical shape grater shell, fill up the soft plastic board that a layer thickness is the 6-12 millimeter, on soft plastic board, liner plate and press strip close proximity, make up in aggregates, the concrete practice is every several liner plates one press strip, press strip is fixed by bolts on the shell of grater, between the liner plate and liner plate and fixing close proximity by flat side (as build arch bridge with brick or stone) between the press strip.The quantity of the required monolithic liner plate of each grater and the size and the weight of every block of liner plate, size and convenient installation the according to the grater diameter, the principle of carrying, definite by calculating, general monolithic liner plate length along the circumferential direction is the 250-350 millimeter, length in axial direction is 3-4 times of used medium maximum gauge, the weight of every block of liner plate is advisable with the 15-40 kilogram, generally be no more than 50 kilograms, the quantity of press strip and size are also decided on the diameter of grater, the grater less to diameter, each circumference 3-6 piece press strip, the length of the length of press strip and monolithic liner plate matches, the thick 40-60 millimeter of press strip major part, lining material is looked the working condition difference and is selected medium manganese nodular cast iron for use, middle low-alloy chilled cast iron, middle-low alloy steel, rubber or other materials manufacturing, press strip can be used the material manufacturing identical or inequality with liner plate, as available potassium steel or carbon steel manufacturing.

Compared with prior art, the utlity model has following advantage:

1, structure and manufacturing, installation are simple;

2, design is made up by a plurality of fritters easily, and flexibility is big, convenient in carrying, and labour intensity is little;

3, the area of every block of liner plate is little, and impulsive force is also little, even adopt fragile material, the possibility that fracture takes place also significantly reduces;

4, the slurry that is mixed with water by the material that ground is mixed the situation that spills and pollute and is significantly reduced from grater.

The drawing explanation:

Fig. 1 be arch combination press strip liner plate the monolithic liner plate face sketch.

Fig. 2 is the side diagrammatic cross-sectional view of the monolithic liner plate of arch combination press strip liner plate.

Fig. 3 is the positive diagrammatic cross-sectional view of the press strip of arch combination press strip liner plate.

Fig. 4 is the side diagrammatic cross-sectional view of the press strip of arch combination press strip liner plate.

Fig. 5 is the scheme of erection of arch combination press strip liner plate.

Below in conjunction with drawings and Examples the utility model is further specified:

Can find out that from Fig. 1 and Fig. 2 the monolithic liner plate of the arch combined lining board of cylindrical shape grater is entad and square flat side down, the surface is a waveform, and the maximum difference of it and present widely used punching liner plate is the hole that it does not wear bolt.

Can find out that from Fig. 3 and Fig. 4 press strip is the rectangular of the less and flat side down of thickness, there is the hole of passing screw at its center, and its radical length equates with the radical length of liner plate.

In Fig. 5, pad one layer thickness is the soft plastic board (2) of 10 millimeter between shell of cylindrical shape grater (1) and the monolithic liner plate (3), its effect is buffering, damping and sound insulation, be close to the close connection that combines between the monolithic liner plate (3) and between monolithic liner plate (3) and the press strip (7), press strip (7) is fixed on the shell (1) of cylindrical shape grater with bolt (4,5,6).

Claims

1, a kind of arch combination press strip liner plate of the cylindrical shape grater that combines by parts such as monolithic liner plate and bolts, it is characterized in that monolithic liner plate (3) is entad and square flat side down, the surface is waveform or flat shape, press strip (7) is that the axial length of axial length and liner plate (3) coincide, thick (wide) spends the rectangular of less and flat side down, its center has one to pass screw (4,5,6) hole, on the inner surface of cylindrical shape grater shell (1), fill up the soft plastic board that a layer thickness is the 6-12 millimeter (2), tight arrangement liner plate (3) and press strip (7) on soft plastic board (2), with a press strip (7), press strip (3) is fixed by bolts on the shell (1) of grater every several liner plates.

2, the arch of cylindrical shape grater as claimed in claim 1 combination press strip liner plate is characterized in that monolithic liner plate length along the circumferential direction is the 250-350 millimeter, and length vertically is 3-4 times of used medium maximum gauge.
