Description

[Technical Field]

[0001] The present invention relates to the technical field of hoppers, and more particularly to an anti-wear device for ball mill inlet hopper structures. [Background technology]

[0002] A ball mill is a machine that crushes coal lumps and pulverizes them into fine coal, and is an important auxiliary equipment for a pulverized coal combustion furnace. The crushing process uses the impact crushing and pulverizing effect of a rotating abrasive body on the coal lumps to finely pulverize the raw material.

[0003] In existing ball mill applications, the coal lumps to be crushed are fed into the hopper through the opening at the top, where they come into direct contact with the buffer wear surface, generating significant impact and friction. They are then led into the ball mill from the bottom of the hopper. Over a long period of time, the hopper's buffer wear surface can become worn through and completely worn out due to the impact and friction from the coal lumps in the ball mill, significantly shortening its service life and requiring frequent shutdowns for inspection and maintenance, resulting in reduced efficiency and increased production costs.

[0021] Furthermore, the present invention will be described in detail in conjunction with schematic drawings, and when describing the embodiments of the present invention in detail, for ease of explanation, the cross-sectional views showing the structure of the device are partially enlarged and not according to the normal scale, and the schematic drawings are merely illustrative and do not limit the scope of protection of the present invention, and should include three-dimensional spatial dimensions of length, width and depth during actual production.

[0022] Example 1 1 to 4, a wear prevention device having a ball mill inlet hopper structure is provided, and the device includes a protection mechanism 100 including a flange 101, a supply pipe 102 provided on the flange 101, a transport section 103 and an inspection section 104 provided on the supply pipe 102, and a wear prevention section 105 provided on the transport section 103.

[0023] Here, a flange 101 is provided at the top of the supply pipe 102, and the supply pipe 102 is connected to other pipes via the flange 101.

[0024] Furthermore, the transport section 103 includes an inclined pipe 103a provided in the supply pipe 102 and a discharge pipe 103b provided in the supply pipe 102.

[0025] Here, the inclined pipe 103 a is provided at the bottom of the supply pipe 102 .

[0026] Here, one end of the inclined pipe 103a remote from the supply pipe 102 is connected to the discharge pipe 103b.

[0027] Specifically, the raw coal that has fallen into the supply pipe 102 passes through an inclined pipe 103a and is discharged from a discharge pipe 103b into the interior of the processing facility.

[0028] Furthermore, the inspection unit 104 includes an inspection port 104a provided in the supply pipe 102, a cover plate 104b provided in the inspection port 104a, and a handle 104c provided in the cover plate 104b.

[0029] Here, an inspection port 104a is provided in the side wall of the supply pipe 102, and the inspection port 104a is located on one side away from the discharge pipe 103b.

[0030] Here, the cover plate 104b is attached to the side wall of the supply pipe 102 by bolting.

[0031] Specifically, it becomes easier for workers to enter the inside of the supply pipe 102 and perform inspection.

[0032] Furthermore, the wear prevention part 105 includes a grid 105a provided on the inclined pipe 103a, and a rotation shaft 105b provided on the grid 105a.

[0033] Here, the bottom of the grid 105a is kept airtight.

[0034] Here, the grid 105a is fixedly connected to a rotating shaft 105b, and both ends of the rotating shaft 105b are connected to the inner wall of the supply pipe 102, respectively.

[0035] During operation, to prevent the falling raw coal from directly colliding with the inclined pipe 103a and causing deformation, the workers install a grid 105a inside the inclined pipe 103a. When the raw coal falls from the supply pipe 102 into the grid 105a, the raw coal fills the grooves of the grid 105a and forms a raw coal buffer layer, thereby preventing the raw coal from directly impacting the inner wall of the inclined pipe 103a.

[0036] Example 2 1 to 4, this embodiment differs from embodiment 1 in that it includes a support mechanism 200, which includes an arc-shaped cross section 201 provided on the supply pipe 102, a support section 202 provided inside the arc-shaped cross section 201, a fixed plate 203 provided on the transport section 103, a top section 204 provided on the fixed plate 203, and a buffer section 205 provided on the top section 204.

[0037] Here, an arc-shaped cross section 201 is provided on the inner wall of the supply pipe 102, and one end of the grid element 105a is located inside the arc-shaped cross section 201.

[0038] Furthermore, the support portion 202 includes an arc surface 202a provided on the grid element 105a, a first cross section 202b and a second cross section 202c provided on the grid element 105a, and a support block 202d provided on the inclined pipe 103a.

[0039] Here, an arcuate surface 202 a is provided at one end of the grid element 105 a adjacent to the rotation axis 105 b , and the arcuate surface 202 a is adapted to the dimensions of the arcuate cross section 201 .

[0040] Specifically, when the grid body 105a is in a horizontal position, a portion of the arc-shaped cross section 201 is exposed to the outside, and a portion of the raw coal penetrates into the interior of the arc-shaped cross section 201. When the grid body 105a comes into contact with the bottom surface of the interior of the inclined pipe 103a, the grid body 105a is configured to push out the raw coal inside the arc-shaped cross section 201.

[0041] Here, a first cross section 202b and a second cross section 202c are provided at one end of the grid element 105a adjacent to the rotation axis 105b.

[0042] Here, a support block 202d is provided on the bottom surface inside the inclined pipe 103a.

[0043] Specifically, when the top of the support block 202d is in a horizontal position and the first cross section 202b is in contact with the top of the support block 202d, the lattice member 105a is in a horizontal position. At this time, when a force is applied to the lattice member 105a, the force is received by the support block 202d, and the pressure on the rotation axis 105b is reduced. Furthermore, when the second cross section 202c is in contact with the support block 202d, the lattice member 105a is in contact with the bottom surface inside the inclined pipe 103a.

[0044] Furthermore, the top portion 204 includes a first arc-shaped tube 204a provided on the fixed plate 203, a second arc-shaped tube 204b provided on the first arc-shaped tube 204a, and a first spring 204c provided on the second arc-shaped tube 204b.

[0045] Here, the first arc-shaped tube 204a is connected to the inner wall of the fixed plate 203, Here, one end of the second arc-shaped tube 204b is inserted into the side wall of the first arc-shaped tube 204a, Here, one end of the second arc-shaped tube 204b, which is remote from the first arc-shaped tube 204a, passes through the inclined tube 103a and is connected to the bottom of the lattice member 105a.

[0046] Here, both ends of the first spring 204c are connected to the inner walls of the first arc-shaped tube 204a and the second arc-shaped tube 204b, respectively.

[0047] Specifically, when not subjected to pressure from raw coal, the first spring 204c fully extends the second arc-shaped tube 204b, allowing the grid body 105a to contact the upper surface of the inside of the discharge pipe 103b through this second arc-shaped tube 204b, and at this time, the grid body 105a is in a horizontal state.

[0048] Furthermore, the buffer section 205 includes a fixed ring 205a provided on the second arc-shaped tube 204b, a second spring 205b provided on the fixed ring 205a, and a driven ring 205c provided on the second spring 205b.

[0049] Here, a fixing ring 205a is provided on the side wall of the second arc-shaped tube 204b, and the fixing ring 205a is located at the bottom of the second arc-shaped tube 204b.

[0050] A second spring 205b is attached to one side of the fixing ring 205a adjacent to the first arc-shaped tube 204a, and the second spring 205b is fitted into the side wall of the first arc-shaped tube 204a.

[0051] Here, a driven ring 205c is connected to one end of the second spring 205b remote from the fixed ring 205a, and the driven ring 205c is fitted into the side wall of the first arc-shaped tube 204a.

[0052] During operation, in order to further reduce the impact force of the raw coal on the inclined pipe 103a, when the raw coal falls from the supply pipe 102 onto the grid body 105a, the raw coal will flip the grid body 105a, which will flip downward, and the grid body 105a will drive the second arc-shaped tube 204b, which will compress the first spring 204c, and the second arc-shaped tube 204b will move along the side wall of the first arc-shaped tube 204a, thereby achieving the first stage of buffering. Furthermore, as the second arc-shaped tube 204b moves, the fixed ring 205a moves accordingly, and the fixed ring 205a drives the second spring 205b to move the driven ring 205c. When the driven ring 205c contacts the side wall of the fixed plate 203, the movement of the driven ring 205c is blocked. In this state, the second arc-shaped tube 204b continues to move, and the second arc-shaped tube 204b moves the fixed ring 205a, which contracts the second spring 205b, achieving a second stage of buffering. As a result, the grid 105a gently contacts the bottom surface inside the inclined tube 103a. During the process of inverting the grid 105a, the grid 105a discharges a small amount of raw coal from the inside of the arc-shaped cross section 201, and one end of the grid 105a completely blocks the arc-shaped cross section 201.

[0053] Example 3 1 to 5, this embodiment differs from the above-described embodiments in that it includes a locking mechanism 300, which includes a limit section 301 provided in the supply pipe 102, a slide groove 302 provided in the transport section 103, a first through hole 303 and a second through hole 304, a lifting section 305 provided inside the first through hole 303, a locking section 306 provided inside the second through hole 304, and an unlocking section 307 provided in the locking section 306.

[0054] Here, the slide groove 302 is provided on the outer upper surface of the discharge pipe 103b.

[0055] Here, the first through hole 303 communicates with the slide groove 302 , and the second through hole 304 communicates with the slide groove 302 .

[0056] Furthermore, the limiter 301 includes an insertion hole 301a provided in the inclined pipe 103a and an insertion rod 301b provided in the lattice member 105a, Here, there are a plurality of insertion holes 301a, and the plurality of insertion holes 301a are uniformly distributed in the inclined pipe 103a. Here, the insertion rod 301b is provided at the bottom of the grid body 105a.

[0057] Specifically, when the insertion rod 301b is inserted into the insertion hole 301a, the lattice element 105a comes into contact with the bottom surface of the interior of the inclined tube 103a, further restricting the position of the lattice element 105a and preventing the lattice element 105a from damaging the rotating shaft 105b.

[0058] Furthermore, the lifting unit 305 includes a vertical bar 305a provided inside the first through-hole 303, a lifting block 305b provided on the vertical bar 305a, and a top plate 305c provided on the supply pipe 102.

[0059] Here, there are two first through holes 303, and a vertical bar 305a is provided inside each of the two first through holes 303.

[0060] Here, two vertical bars 305a are connected to each other by a lifting block 305b.

[0061] Specifically, when the top of the grid 105a contacts the upper surface of the inside of the discharge pipe 103b, both of the two vertical bars 305a are located inside the first through-hole 303.

[0062] Here, the top plate 305c is located at the top of the vertical bar 305a, Specifically, the structure is such that the vertical rod 305a is prevented from falling out from inside the first through hole 303.

[0063] Furthermore, the locking portion 306 includes a fixed rod 306a provided on the lattice body 105a, a sliding rod 306b provided inside the slide groove 302, a lock block 306c provided on the sliding rod 306b, a third through hole 306d and a third spring 306e provided on the lock block 306c, and a fixed block 306f provided on the third spring 306e.

[0064] Here, a fixed rod 306a is connected to one end of the grid element 105a remote from the rotation axis 105b.

[0065] Here, both ends of the slide bar 306b are connected to the inner wall of the slide groove 302, Here, the lock block 306c is inserted into the side wall of the slide bar 306b, and the top of the lock block 306c protrudes outside the slide groove 302, while the bottom of the lock block 306c extends into the inside of the discharge pipe 103b.

[0066] Specifically, the width of the lock block 306 c is set to correspond to the width of the slide groove 302 .

[0067] Here, a third through hole 306d is provided on one side of the lock block 306c adjacent to the fixing rod 306a.

[0068] Specifically, when the fixed rod 306a is positioned inside the third through hole 306d, the grid body 105a is supported by installing the support block 202d and the lock block 306c, allowing some of the raw coal to be collected in the grid body 105a, enabling the rapid formation of a buffer layer.

[0069] Here, the third spring 306e is fitted into the side wall of the sliding bar 306b.

[0070] Specifically, one end of the third spring 306e is connected to the side wall of the lock block 306c.

[0071] Here, the other end of the third spring 306e is connected to a fixed block 306f.

[0072] Specifically, the fixing ring 205 a is fixedly installed inside the slide groove 302 .

[0073] Furthermore, the unlocking section 307 includes a driven rod 307a provided on the lock block 306c, a recessed groove 307b provided on the driven rod 307a, an article storage groove 307c provided on the supply pipe 102, and an inversion plate 307d provided inside the article storage groove 307c.

[0074] Here, a driven rod 307a is provided on one side of the lock block 306c adjacent to the supply pipe 102, and one end of the driven rod 307a remote from the lock block 306c can be inserted into the article receiving groove 307c.

[0075] Specifically, the driven rod 307a is located between the two vertical rods 305a, and when no external force is applied to the vertical rods 305a, Here, a groove 307b is provided on the side wall of the driven rod 307a, and the groove 307b is located at the top of the driven rod 307a.

[0076] Here, the article receiving groove 307c is provided on the inner wall of the supply pipe 102 and is located on one side adjacent to the driven rod 307a.

[0077] Specifically, when no external force is applied to the reversing plate 307d, the reversing plate 307d is completely housed inside the article housing groove 307c.

[0078] Specifically, when the grid element 105a is not in a horizontal position, the lifting block 305b is located inside the recessed groove 307b, and the third spring 306e is in an extended state.

[0079] During operation, in order to ensure the rapid formation of a buffer layer on the grid body 105a and reduce the instantaneous impact force of the raw coal, when coal transportation is not in operation, the restoring force of the first spring 204c causes the second arc-shaped tube to rise along the side wall of the first arc-shaped tube 204a, and the second arc-shaped tube 204b flips the grid body 105a upward, and in conjunction with this, the grid body 105a rotates the rotating shaft 105b. When the top of the grid body 105a comes into contact with the upper surface of the inner wall of the discharge pipe 103b, the first cross section 202b comes into contact with the top of the support block 202d, and during the process of the grid body 105a reversing upward, the grid body 105a raises the vertical rod 305a, and the vertical rod 305a causes the lifting block 305b to separate from the inside of the groove 307b. At this time, due to the restoring force of the third spring 306e, the lock block 306c slides along the side wall of the sliding rod 306b, thereby inserting the fixed rod 306a into the inside of the third through hole 306d, completing the fixation of the grid body 105a, and the driven rod 307a reversing the reversal plate 307d upward.

[0080] During the raw coal transport operation, the raw coal falls from the supply pipe 102 onto the grid 105a, and a certain amount of the raw coal accumulates, forming a buffer layer on the top of the grid 105a. At the same time, the reversing plate 307d is pushed into the article storage groove 307c during the falling process of the raw coal. During the reversing operation of the reversing plate 307d, the reversing plate 307d moves the driven rod 307a, and the driven rod 307a moves the lock block 306c along the side wall of the sliding rod 306b, so that the lock block 306c is released from the fixed rod 306a. At this time, under the action of gravity of the raw coal, the raw coal The coal causes the grid 105a to flip downward, which in turn causes the second arc-shaped tube 204b to descend, which in turn causes the first spring 204c to contract, thereby achieving the first stage of buffering. The second arc-shaped tube 204b then causes the driven ring 205c to contact the fixed plate 203, which then causes the second arc-shaped tube 204b to contract the second spring 205b, thereby achieving the second stage of buffering. This operation continues until the bottom of the grid 105a contacts the inner bottom surface of the inclined tube 103a, at which point the second cross section 202c contacts the support block 202d, and the raw coal is transported normally.

[0081] As the grid 105a descends, the vertical rod 305a is no longer supported by the grid 105a and descends. The vertical rod 305a then descends the lifting block 305b, causing the lifting block 305b to come into contact with the side wall of the driven rod 307a. When the raw coal flips the reversing plate 307d, the reversing plate 307d moves the driven rod 307a. As a result, the groove 307b on the driven rod 307a moves below the lifting block 305b, and the lifting block 305b enters the groove 307b again. This completes the fixation of the locking block 306c and makes it easier to fix the grid 105a the next time.
