Description

Domestic waste storage device Technical Field

[0001] The present invention relates to the field of garbage storage equipment, and more particularly to a domestic garbage storage device. Background Art

[0002] Municipal domestic waste will be transferred to the garbage pool for storage before incineration. During the storage process, the domestic waste will be bio-composted in the garbage pool for 5 to 7 days. During this process, the leachate in the domestic waste will enter the leachate collection pool from the seepage holes at the bottom of the garbage pool. After bio-composting, the water content of domestic waste can be significantly reduced, thereby increasing the calorific value of domestic waste. The domestic waste after bio-composting will be put into the waste incinerator for incineration. During the transfer of domestic waste, lifting equipment and grab buckets are usually used to cooperate with each other to transfer domestic waste to the required place. Existing garbage pools for storing domestic garbage are usually warehouse structures. The existing patent with application number 201310546590.3 discloses a double-pool garbage storage, which is provided with a partition wall in the garbage storage, dividing the garbage storage into garbage pool A and garbage pool B. A row of unloading doors are provided in the upper middle part of the front wall of garbage pool A, and an unloading hall is provided in front of the unloading door. An unloading platform is provided in the unloading hall, and the unloading platform is connected to the trestle. An incinerator feeding platform is provided above the rear wall of garbage pool B, and a bridge-type lifting equipment is provided above garbage pools A and B. The bridge-type lifting equipment is provided with a grab bucket. A grab bucket maintenance platform is provided above the right end wall of garbage pool A, and a grab bucket lifting hole is provided on the grab bucket maintenance platform, and a sealing cover plate is provided on the grab bucket lifting hole. In the above structure, when in use, the grab bucket grabs the preliminarily fermented and dehydrated domestic waste in garbage pool A and transfers it to garbage pool B for secondary fermentation. After the secondary fermentation, the grab bucket grabs the domestic waste in garbage pool B and transfers it to the incinerator's feed port, allowing the domestic waste to enter the waste incinerator for incineration. When the grab bucket requires overhaul, it is transported to the grab bucket's hoisting hole via a bridge crane and lowered from the hoisting hole to the maintenance platform for inspection. However, in the above structure, when the grab bucket requires maintenance, the space on the maintenance platform below the hoisting hole is easily contaminated by the hoisting hole and the garbage or odor carried by the grab bucket itself, resulting in a poor working environment for maintenance personnel.

[0040] In this technical solution, during use, when the grab bucket 6 needs a major overhaul, the bridge crane 4 will lift the grab bucket 6 to the grab bucket perforation 8, and drop the grab bucket 6 from the grab bucket perforation 8 until the grab bucket 6 is placed on the filter plate 21. The bridge crane 4 can lower more of the wire rope 14 to make the connection between the hook 16 and the lifting ring 15 not tight, which is convenient for disassembly; at this time, the top of the grab bucket 6 is the lifting ring and the bottom is the garbage grabbing end, and then the operating cabin 10 is prompted to slide out of the operating room 9 to one end of the operating cabin 10 suspended in the maintenance room 2. At this time, the operating cabin 10 is provided with an operating glove 11 at one end near the lifting ring 15. The operator puts his hand into the operating glove 11 and uses the operating glove 11 to lift the lifting ring 15 of the grab bucket 6 from the bridge crane The hook 16 of the equipment 4 is disassembled to prevent direct contact between the grab bucket 6 and the hands. Then the wire rope 14 of the bridge crane 4 is retracted from the grab bucket perforation 8 to the storage tank 1. The sealing cover seals the grab bucket perforation 8 to prevent the odor in the storage tank 1 from being emitted into the maintenance room 2. Then the cleaning nozzle 19 flushes the grab bucket 6. The flushed garbage is left on the filter plate 21. The flushed water flows into the filtrate collection tank 18 below the filter plate 21 and is discharged to the external sewage collection device through the water pipe. The garbage on the filter plate 21 passes through the vibrator 22 and slides from the inclined filter plate 21 into the collection tank 18. When the cleaning is completed, the grab bucket 6 is initially restored to cleanliness, which can improve the working environment of subsequent maintenance personnel and reduce the odor in the working environment.

[0041] The adoption of this technical solution has the beneficial effect that, by arranging a storage warehouse 1, a feed door, a garbage incineration platform 31, a feeding port 32, a track 3, a bridge crane 4, a grab 6, a maintenance room 2, a grab through-hole 8, a sealing cover, a first opening and closing door, an operating room 9, a second opening and closing door, an operating cabin 10, a third opening and closing door, a through-hole 12, operating gloves 11, an operating platform 17, a grab cleaning tank 7, a collection tank 18, a discharge port 20, a filter plate 21, a vibrator 22, and a drain port, the grab 6 is rinsed clean before maintenance, which will avoid the emission of odor and improve the working environment of the maintenance personnel.

[0042] When the operating platform 17 is in the maintenance room 2, the support legs 13 are extended to drive the cleaning trough 7 upward so that the top of the cleaning trough 7 is close to the end of the operating cabin 10 and the bottom of the operating cabin 10 are in contact with each other to form a support; specifically, a pair of drivable and retractable support legs 13 are provided on the inner bottom wall of the maintenance room 2, and the retractable ends of the pair of support legs 13 are upward and fixedly connected to the operating platform 17 to drive the operating platform 17 to rise and fall in the vertical direction. The support legs 13 can be hydraulic cylinders or hydraulic rods; when in use, the end of the operating cabin 10 close to the maintenance room 2 is first slid out of the operating room 9, and then the retractable ends of the support legs 13 are moved upward to drive the operating platform 17 to move upward so that the top of the cleaning trough 7 is close to the end of the operating cabin 10 and the bottom of the operating cabin 10 are in contact with each other to form a support. The bottom of the cabin 10 abuts to form a support for the operating cabin 10; in actual use, considering the pressure exerted by the operating cabin 10 on the grab cleaning tank 7, a pull rope (not shown in the figure) can be set on the side wall of the grab cleaning tank 7 away from the operating cabin 10, one end of the pull rope is connected to the grab cleaning tank 7, and the other end is connected to the inner wall of the maintenance room 2 (which can be a side wall or a bottom wall). When the top of the grab cleaning tank 7 abuts the bottom of the operating cabin 10, it is stretched and tightened, which can provide tension to the side wall of the grab cleaning tank 7, and can reduce the impact of the unbalanced pressure on both ends of the grab cleaning tank 7 caused by the operating cabin 10; the use of this technical solution has the beneficial effect of designing a drivable and retractable support leg 13. When the support leg 13 is extended, the connection between the hook 16 and the ring 15 is not tight, and the grab cleaning tank 7 abuts the bottom of the operating cabin 10 to form a support, which can improve the support stability of the operating cabin 10. Under the premise of ensuring the support stability of the operating cabin 10, the setting area of ​​the operating room 9 can be minimized.

[0043] In another technical solution, a placement groove 23 is provided on one side wall of the grab bucket cleaning trough 7, in which the grab bucket 6 to be replaced is placed; when in use, the operator removes the grab bucket 6 to be repaired from the bridge-type lifting equipment 4, and then connects the grab bucket 6 to be replaced (new grab bucket 6) in another grab bucket cleaning trough 7 to the bridge-type lifting equipment 4, and then the bridge-type lifting equipment 4 retracts the new grab bucket 6 from the grab bucket perforation 8 to the storage warehouse 1, and the sealing cover seals the grab bucket perforation 8 to prevent the odor in the storage warehouse 1 from being emitted into the maintenance room 2, so that the normal operation of the garbage in the storage warehouse 1 can be ensured; the beneficial effect of adopting this technical solution is that by designing the placement groove 23, the new grab bucket 6 is placed in the placement groove 23, and the grab bucket 6 to be repaired can be replaced in time, and the new grab bucket 6 can be installed on the bridge-type lifting equipment 4, so as to ensure the normal operation of the garbage in the storage warehouse 1.

[0044] In another technical solution, the grab cleaning tank 7 is square, and a soft pad 39 is laid at one end of the top of the grab cleaning tank 7 that abuts against the bottom of the operation cabin 10; the soft pad 39 can be a rubber pad or a silicone pad, etc. When in use, the soft pad 39 abuts against the bottom of the operation cabin 10. By adopting this technical solution, the beneficial effect is that by designing a rubber pad or a silicone pad, the friction between the operation cabin 10 and the top of the grab cleaning tank 7 can be increased, and at the same time, the contact wear between the operation cabin 10 and the top of the grab cleaning tank 7 can be reduced.

[0045] In another technical solution, there are multiple through holes 12. The multiple through holes 12 are a row of through holes 12 arranged at intervals, and a U-shaped hook plate 38 is provided between two adjacent through holes 12. The hook plate 38 is used to hook the steel wire rope 14 of the bridge crane 4. Specifically, an operation glove 11 is provided at each through hole 12.
