An efficient and environment-friendly garbage incinerator device according to an embodiment of the present invention will be described with reference to fig. 1 to 19.

As shown in fig. 1, the efficient and environment-friendly garbage incinerator equipment of the embodiment of the invention comprises a feeding device a, a feeding device B, a grate device C and a slag discharging device D;

the feeding device B is positioned between the feeding device A and the fire grate device C;

the grate device C comprises a drying section grate C1, a combustion section grate C2 and a burnout section grate C3 which are all forward-pushing grates, garbage sequentially passes through the drying section grate C1, the combustion section grate C2 and the burnout section grate C3, and forward-pushing hydraulic cylinders C4 are arranged at the bottoms of the drying section grate C1, the combustion section grate C2 and the burnout section grate C3;

the drying section grate c1, the combustion section grate c2 and the burnout section grate c3 are respectively covered with a lower ash hopper c5, the top of the lower ash hopper c5 is provided with a sealing box device E, and a hydraulic rod of the forward pushing hydraulic cylinder c4 penetrates through the sealing box device E and then is connected with the grates;

the feeding device B is used for conveying the garbage in the feeding device A to the drying section grate c 1;

the slag discharging device D is positioned at the tail end of the burnout section grate c3 and is used for receiving slag discharged from the burnout section grate c 3.

The garbage incinerator equipment provided by the embodiment of the invention comprises a feeding device A, a feeding device B, a grate device C and a slag discharging device D, wherein after garbage is fed into the feeding device A, the feeding device B moves the garbage to a drying section grate C1, based on three sections of grates, a forward pushing grate is adopted, the grate pushes the garbage to pass through the drying section grate C1, a combustion section grate C2 and a burnout section grate C3 once, the formed slag falls from the burnout section grate C3 to the slag discharging device D, the slag discharging device D carries the slag, and the slag falling from the grate is discharged through a lower ash hopper C5. All devices of the garbage incinerator equipment can be controlled by the control device to perform cooperative action, so that automatic garbage incineration is realized, and the garbage treatment efficiency is improved.

Based on the problems that ash affects the work of the forward pushing hydraulic rod c4 and ash leaks from the joint of the hydraulic rod of the forward pushing hydraulic cylinder c4 and the lower ash bucket c5 in the prior art, the sealing box device E is arranged at the top of the lower ash bucket c5 in the embodiment of the invention, so that the sealing performance of the joint of the hydraulic rod of the forward pushing hydraulic cylinder c4 and the lower ash bucket c5 is improved.

As shown in fig. 2 and 3, in particular, the sealing box device E includes a sleeve E100, a gland E200 and a sealing sleeve ring structure E300. The sealing sleeve ring structure e300 is an annular structure formed by arranging packing e310 and alumina silicate fiber rope rings e320 at intervals, and a layer of alumina silicate fiber rope rings e320 is clamped between two layers of packing e 310. The inner wall of the sleeve e100 is provided with a boss e110, and the boss e110 abuts against the rear end of the sealing collar structure e 300. The gland e200 is adjustably mounted on the end of the sleeve e100 in the axial direction of the sleeve e100, and abuts against the front end of the seal collar structure e 300.

After the hydraulic rod of the forward-pushing hydraulic cylinder c4 penetrates into the sleeve e100, the inner wall of the sealing sleeve structure e300 abuts against the hydraulic rod of the forward-pushing hydraulic cylinder c4, so that the gap between the hydraulic rod of the forward-pushing hydraulic cylinder c4 and the sleeve e100 is filled, and therefore ash residues are prevented from leaking outwards from the gap between the hydraulic rod of the forward-pushing hydraulic cylinder c4 and the sleeve e 100. When the hydraulic rod of the forward-pushing hydraulic cylinder c4 vibrates or is eccentric, the sealing sleeve ring structure e300 formed by the packing e310 and the aluminum silicate fiber rope ring e320 has certain compensation capacity, so that the hydraulic rod of the forward-pushing hydraulic cylinder c4 is prevented from colliding with the sleeve e 100.

By adjustably covering the gland e200 at the end of the sleeve e100 along the axial direction of the sleeve e100, when the sealing performance needs to be improved, the gland e200 is adjusted backwards along the axial direction of the sleeve e100, the sealing sleeve ring structure e300 is further compressed, the sealing sleeve e100 is expanded transversely due to compression, the inner wall of the sealing sleeve ring is further attached to the hydraulic rod of the forward-pushing hydraulic cylinder c4, the sealing performance is improved, and ash slag is effectively prevented from leaking from a gap between the hydraulic rod of the forward-pushing hydraulic cylinder c4 and the sleeve e 100.

It is worth to be noted that, because the packing E310 has good elasticity, the aluminum silicate fiber rope ring E320 has high temperature resistance, good thermal stability and small thermal expansion, a layer of the aluminum silicate fiber rope ring E320 is clamped between every two layers of the packing E310 to form a stable sealing structure with small thermal expansion, and the service life of the sealing box device E can be prolonged under the high-temperature environment in the incinerator.

Specifically, as shown in fig. 2, the pressing cover e200 is provided with an avoiding hole e210 through which a hydraulic rod of the forward-pushing hydraulic cylinder c4 passes, a cover pressing ring e220 is arranged on the inner wall of the pressing cover e200 at the periphery of the avoiding hole e210, and the cover pressing ring e220 is embedded in the sleeve e100 and abuts against the front end of the sealing cover ring structure e 300. In this way, when the gland e200 is disposed at the front end of the sleeve e100, the gland boss e220 is fitted into the sleeve e100 to abut against the front end of the seal bushing structure e300, thereby compressing and fixing the seal bushing structure e 300.

In some embodiments, the front end of the sleeve e100 is provided with a connecting flange e120, and the pressing cover e200 is fixedly connected with the connecting flange e120 through a threaded fastener. Specifically, as shown in fig. 2, the threaded fastener includes a stud and a nut, and after the stud passes through the connecting flange e120 and the gland e200, both ends are locked by the nut. Thus, the distance between the connecting flange e120 and the gland e200 can be adjusted by screwing the nut, so that the gland e200 can be adjustably covered on the end of the sleeve e100 along the axial direction of the sleeve e 100. When the sealing performance needs to be improved, the nut is screwed to reduce the distance between the connecting flange e120 and the gland e200, the gland e200 is adjusted backwards along the axial direction of the sleeve e100, the gland convex ring e220 further compresses the sealing sleeve ring structure e300, the sealing sleeve e100 expands transversely due to compression, the inner wall of the sealing sleeve ring further clings to the hydraulic rod of the forward-pushing hydraulic cylinder c4, the sealing performance is improved, and ash slag is effectively prevented from leaking from a gap between the hydraulic rod of the forward-pushing hydraulic cylinder c4 and the sleeve e 100.

As another embodiment of the present invention, the outer wall of the cap pressing ring e220 is provided with an external thread, and the inner wall of the front end portion of the sleeve e100 is provided with an internal thread, and the external thread is screw-engaged with the internal thread. Through the threaded fit of the cover pressing convex ring e220 and the sleeve e100, when the pressing cover e200 is rotated, the cover pressing convex ring e220 moves backwards relative to the sleeve e100, and then the cover pressing convex ring e220 further presses the sealing sleeve ring structure e300, so that the sealing sleeve e100 expands transversely due to compression, the inner wall of the sealing sleeve ring further clings to the hydraulic rod of the forward-pushing hydraulic cylinder c4, the sealing performance of the sealing sleeve is improved, and ash slag is effectively prevented from leaking from a gap between the hydraulic rod of the forward-pushing hydraulic cylinder c4 and the sleeve e 100.

Preferably, the sleeve e100 has a blowing pipe e130, and an air outlet of the blowing pipe e130 is communicated to the inside of the sleeve e100 and is located behind the boss e 110. As shown in fig. 2, since the sleeve e100 still has a gap behind the boss e110, in order to avoid the slag accumulation in the gap between the sleeve e100 and the hydraulic rod of the forward hydraulic cylinder c4, the ash blowing pipe e130 is arranged on the sleeve e100, and the ash blowing pipe e130 is communicated with an external air source such as an air compressor or an air storage tank, so that the ash slag accumulation in the gap between the sleeve e100 and the hydraulic rod of the forward hydraulic cylinder c4 can be carried away by guiding air flow out by the ash blowing pipe e130, thereby avoiding the slag accumulation in the gap between the sleeve e100 and the hydraulic rod of the forward hydraulic cylinder c4, keeping the interior of the sleeve e100 clean, and being beneficial to reducing the abrasion of the hydraulic rod of the forward hydraulic cylinder c 4.

Preferably, the dust-proof device further comprises a dust-proof steel ring e140, wherein the dust-proof steel ring e140 is arranged on the inner wall of the rear end part of the sleeve e 100. Specifically, the ash blocking steel ring e140 is arranged on the inner wall of the rear end part of the sleeve e100 to reduce the size of a gap between the rear end part of the sleeve e100 and a hydraulic rod of the forward-pushing hydraulic cylinder c4, so that the ash blocking steel ring e140 blocks ash falling from a bellows, the ash is prevented from entering the sleeve e100 from the outside, and the ash accumulation in the sleeve e100 is reduced.

Referring to fig. 3, the present embodiment further provides a hydraulic cylinder link device, which includes a hydraulic rod of a forward-pushing hydraulic cylinder c4 and the seal box device for preventing slag leakage of the grate hydraulic cylinder link according to any of the above embodiments, wherein the hydraulic rod of the forward-pushing hydraulic cylinder c4 is inserted into the sleeve e100, and the front end of the hydraulic rod of the forward-pushing hydraulic cylinder c4 is inserted through the gland e 200. The sealing sleeve ring structure e300 is sleeved on the outer wall of the hydraulic rod of the forward pushing hydraulic cylinder c 4. As shown in fig. 3, after the hydraulic rod of the forward-pushing hydraulic cylinder c4 penetrates into the casing e100, the inner wall of the sealing sleeve structure e300 abuts against the hydraulic rod of the forward-pushing hydraulic cylinder c4, so that the gap between the hydraulic rod of the forward-pushing hydraulic cylinder c4 and the casing e100 is filled, and therefore ash residues are prevented from leaking from the gap between the hydraulic rod of the forward-pushing hydraulic cylinder c4 and the casing e 100. When the hydraulic rod of the forward-pushing hydraulic cylinder c4 vibrates or is eccentric, the sealing sleeve ring structure e300 formed by the packing e310 and the aluminum silicate fiber rope ring e320 has certain compensation capacity so as to avoid the collision between the hydraulic rod of the forward-pushing hydraulic cylinder c4 and the sleeve e 100.
