background technique

At present, it is known that the sealing structure of the liner bolt, located on the cylinder body and end caps on both sides of the coal mill device, includes a drum-shaped rubber washer, a cup-shaped steel pad, a liner bolt, a nut and so on. The cup-shaped pad transmits the axial compressive force of the nut to the drum-shaped rubber sealing ring, and forms a seal between the cylinder body and the liner bolts of the coal mill device to prevent water and coal sludge leakage. However, as the service life of the coal mill apparatus increases, water and coal sludge leakage occurs from the holes of the liner bolts of the cylinder body due to the inevitable plastic deformation of the rubber material.

Specifically, the inner wall of the outer liner plate 100 is annularly distributed with first sliding slots 100a and restricting slots 100a-1 provided inside the first sliding slot 100a, the outer liner plate 100 is externally provided with restricting passages 100a-2 communicating with the restricting slots 100a-1, the inner liner panel 200 comprising a first slide block 201 slidably cooperating with the first slide slot 100a, a second slide slot 200a and a second slide block 202 located on either side of its outer wall, and a restraining assembly 204 located outside the first slide block 201 is arranged.

Preferably, the inner liner panel 200 is externally provided with an attachment slot 200b, and the inner liner panel 200 is externally provided with an attachment block 203 insertable into the attachment slot 200b.

When the inner liner panel 200 is to be stacked, the inner liner panel 200 can have some stability by connecting the fixing slot 200b and the fixing block 203 .

In summary, when installing the inner liner panel 200 into the outer liner panel 100, the inner liner panel 200 can be installed into the outer liner panel 100 through the first sliding block 201 and the first sliding slot 100a, and the inner liner panel 200 can be fixed through the restraining assembly 204 can.

Example 2

In the 1 until 5 shows a second embodiment of the utility model, which is based on the previous embodiment, the difference being that a certain limitation is provided to improve the stability of each outer liner panel 100 in stacking and assembly.

Specifically, the outer liner plate 100 is provided with bushings 100b outside, the outer liner plate 100 is provided inside with a movable passage 100b-1 connected to the bushing 100b, the outer liner plate 100 is detachably provided with an insert rod 101 outside, the insertion rod 101 is provided with slits 101a on the outside, the movable passage 100b-1 is provided with a movable block 102 on the inside, one end of the movable block 102 extends into the socket 100b, the other end of the movable block 102 with a Connecting rod 102a is provided, one end of the connecting rod 102a extends beyond the outer liner panel 100 and is provided with a tie rod 102b, the connecting rod 102a being externally provided with a first elastic member 102a-1, the connecting rod 102a externally detachably having a Sleeve 102c is provided, the sleeve 102c is provided externally with a notch 102c-1.

Wherein the first elastic member 102a-1 is a compression spring.
In summary, each outer liner panel 100 can be inserted when stacked along the sleeve 100b by a set of insert rods 101 on the underside of the outer liner panel 100, and when the insert rod 101 passes the moving block 102, the moving block will move 102 move under the force of the first elastic element 102a-1 and cooperate with the slot 101a to complete the clamping.

Wherein, the insert rod 101 is screwed through a screw hole on the outside of the outer liner panel 100 to achieve its detachable function from the outer liner panel 100; when it is necessary to separate each outer liner panel 100, the pull rod 102b is pulled outwards, whereby the connecting rod 102a moves the movable block 102 fully into the movable passage 100b-1, i.e. the clamping with the insertion rod 101 is released, then a sleeve 102c is fitted over the tie rod 102a to prevent the tie rod 102b from being subjected to the force of the first elastic member 102a-1, which causes the movable block 102 to spring back.

Example 3

In the 1 until 5 a third embodiment of the utility model is shown, which is based on the previous embodiment, the difference being that the stability of the inner liner panel 200 during installation can be improved by a restraining assembly 204.

In particular, the restraining assembly 204 comprises a mounting post 204a, the mounting post 204a being externally provided with a movable post 204b, the mounting post 204a being open externally with a third sliding slot 204a-1, the movable post 204b internally having a third sliding block 204b-1 is provided which slides in conjunction with the third sliding slot 204a-1, the movable column 204b being provided inside with a connection cavity 204b-2, the connection cavity 204b-2 being provided inside with a second elastic member 204c, one end of the second elastic member 204c is connected to the outside of the attachment column 204a, the movable column 204b being movably connected to restriction channels 100a-2 outside.

Wherein the second elastic member 204c is a compression spring.
In summary, when the inner liner panel 200 is installed in the outer liner panel 100, the movable column 204b will be slightly compressed, and with the movement of the inner liner panel 200, the movable column 204b will enter the restricting slot 100a-1, and when the lower surface of the inner liner panel 200 is at the same level as the lower surface of the outer liner panel, the movable column 204b is pushed out of the restriction channel 100a-2 by the action of the second elastic member 204c to complete the attachment of the inner liner panel 200 and so on to increase their stability.
