Abstract
The utility model discloses a grinding lining board fastening structure for effectively preventing pulp from seeping to damage a grinding machine. The grinding lining board fastening structure comprises a grinding lining board (1) and a fastening bolt (6), wherein the grinding lining board (1) is provided with a counter bore (2) matched with the fastening bolt; and one side, matched with a cylinder, of the grinding lining board (1) is provided with a sealing gasket groove (3) which corresponds to the counter bore (2) and is matched with a sealing gasket (5). The grinding lining board fastening structure provided by the utility model adopts a deep-hole countersunk bolt-gasket seal dual-fastening structure, so that the fastening bolt cannot be exceedingly abraded before the lining board needed to be changed, and the bolt is prevented from spinning to damage a bolt rod and cause a pulp seeping phenomenon; and meanwhile, the sealing gasket structure improves the sealing intensity between the grinding lining board and the cylinder, so that firstly, the sealing effect is improved, and secondly, the bolt connecting intensity reduced by the deep counter bore is compensated.
Description
Technical field
The utility model belongs to the disintegrating apparatus technical field, is specifically related to a kind of simple in structure, simple installation, can prevent effectively that ore pulp seepage flow from damaging the ore grinding liner plate fastening structure of grinding machine.
Background technology
In semi-autogenous mill cylindrical shell as the equipment of ore grinding, the ore grinding liner plate is installed, liner plate is connected by bolt with cylindrical shell, when threatening cylindrical shell, just needs to change the ore grinding liner plate when the ore grinding wear liner.But between prior art liner plate and cylindrical shell, serious spillage appears in the bolt junction, causes large pinion place to be denuded by ore pulp.If shut down the operating rate that maintenance will affect grinding machine.On-line maintenance, fastening bolt will damage travelling gear, affects environmental sanitation.Spin can occur after bolt is ground to a certain degree, can makes the distortion of grinding mill barrel screw, the bolt abrasion even rubs (Fig. 1), brings great potential safety hazard and economic loss.For this reason, development is a kind of can prevent effectively that the ore grinding liner plate of fastening bolt damage and the fastening structure of cylindrical shell from being the key that addresses this problem.
The utility model content
It is a kind of simple in structure that the purpose of this utility model is to provide, simple installation, and implementation cost is cheap, can prevent effectively that ore pulp seepage flow from damaging the ore grinding liner plate fastening structure of grinding machine.
The purpose of this utility model is to realize like this, comprise ore grinding liner plate and fastening bolt, the counter sink that is complementary with the fastening bolt cap is set on described ore grinding liner plate, the gasket slot that described ore grinding liner plate is corresponding with cylindrical shell cooperation one side setting and counter sink matches with sealing gasket with gasket slot.
The utility model adopts the dual fastening structure of deep hole dormant bolt-gasket seal, makes fastening bolt can excessively do not denuded before needs are changed liner plate, and causes the bolt spin, damages shank of bolt, causes the generation of ore pulp percolation phenomenon; Simultaneously, gasket structure improves the sealing intensity between ore grinding liner plate and cylindrical shell, and the one, improved sealing effectiveness, the 2nd, made up the bolt bonding strength that reduces because of dark counter sink.The utility model is simple in structure, simple installation, and implementation cost is cheap, can prevent effectively that ore pulp seepage flow from entering gear mechanism and damaging the generation of the phenomenon of grinding machine, has extended the non-maintaining phase of grinding machine, has improved operating efficiency and economic benefit.
Description of drawings
Fig. 1 is fastening bolt distress condition key diagram under the prior art condition;
Fig. 2 the utility model counter sink structure partial schematic diagram;
Fig. 3 is the utility model duty partial schematic diagram;
In figure: 1-ore grinding liner plate, the 2-counter sink, the 3-gasket slot, the 4-cylindrical shell, the 5-sealing gasket, the 6-bolt, 7-denudes the position.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described, but never in any form the utility model is limited, any conversion or replacement based on the utility model training centre is done all belong to protection domain of the present utility model.
As shown in Figure 2 and Figure 3, the utility model comprises ore grinding liner plate 1 and fastening bolt 6, the counter sink 2 that is complementary with the fastening bolt cap is set on described ore grinding liner plate 1, the gasket slot 3 that described ore grinding liner plate 1 is corresponding with cylindrical shell cooperation one side setting and counter sink 2 matches with sealing gasket 5 with gasket slot 3.
Described ore grinding liner plate 1 thickness is 1.1 ~ 1. 5 times of common ore grinding liner plate thickness.
Described counter sink 2 is square cone structure, is complementary with the fastening bolt cap of square cone structure.
The nut thickness 1.1 that described counter sink 2 degree of depth are fastening bolt ~ 1. 5 times.
It is 15 ~ 35mm that the screw rod of described ore grinding liner plate 1 upper bolt hole coordinates segment length.
The degree of depth of described gasket slot 3 is 8 ~ 10mm.
Described sealing gasket 5 is magnetic gasket.
Described counter sink 2 is the hexagon cone structure, is complementary with the fastening bolt cap of hexagon cone structure.
The utility model operation principle and the course of work:
The utility model is deepened counter sink by thickening ore grinding liner plate, and sets up the complex technique measure such as sealing gasket, has prevented that fastening bolt is because the liner plate abrasion causes becoming flexible, the bolt that causes that spins is denuded (Fig. 1).Hermetically-sealed construction has further reduced the possibility of seepage flow ore pulp.Adopt the utility model can make as the problem of the serious spillage of semi-autogenous mill bolt of cover appearance and stopped, extended the service life of grinding machine gear, eliminated potential safety hazard, avoided environmental pollution; Reduced the number of times of fastening bolt, the operating rate of grinding machine can have been brought up to more than 90% by 68% left and right.
