Description

TECHNICAL FIELD

[0001] The utility model relates to garbage treatment technical field, concretely relates to a drainage grate suitable for garbage pit. BACKGROUND

[0002] In the garbage incineration industry, garbage storage pit is essential, and the garbage storage pit provides turnover space for the storage, fermentation and drainage of garbage. To improve the calorific value and combustibility of garbage, it is crucial to improve the drainage rate of garbage. The usual practice is to arrange a drainage hole or a drainage grid through the side wall of the bottom of the garbage pit, so that the water in the garbage can be drained into the leachate collection tank along the drainage hole, and the garbage is blocked in the garbage pit.

[0003] However, it is not what we want, and garbage is very easy to block these drainage holes with a diameter of about 10 cm. Since the garbage pit is full of garbage, the staff cannot enter the garbage pit to clean up, but can only use tools such as iron rods and steel pipes to dredge from the leachate pit side (and the drainage hole outlet side). However, it cannot play a long-term role, and needs to be cleaned up every day. Since the leachate pit is a confined space where flammable, explosive, toxic and harmful gases may occur, the risk of frequent manual entry is high. Therefore, a device is needed that can prevent garbage from blocking the drainage hole for a long time and keep the drainage smooth.

[0004] Chinese patent application 202121393862.7 discloses a garbage pit drainage grate for garbage incineration plant, which is a large grate installed on the drainage hole wall of the garbage pit by bolts to block garbage from entering and blocking the drainage hole. Since the grate needs to be fixed on both sides by bolts, it must be installed and constructed by entering the garbage pit. Since the garbage in the pit cannot be emptied after the garbage incineration project is put into production, the installation must be completed at the beginning of the project construction, and the maintenance and replacement after corrosion and wear are more troublesome.

[0005] Chinese patent application 201510572773.1 discloses a detachable drainage hole filter plug and its installation method, which is mainly suitable for relatively clean natural water such as pumped storage power station, while the water discharged from garbage contains a large amount of debris and dirt, which is more likely to be blocked after using this filter plug, making it difficult to drain.

[0031] In this embodiment, the grate assembly 4 is formed by hinging a plurality of folding arms 2 to the connecting head 1, and there is a gap between adjacent folding arms 2; when the grate assembly 4 is installed, the installation rod 3 is used to push the grate assembly 4 to move in the drainage hole 5 of the garbage pit, and after the grate assembly 4 moves to the end of the drainage hole 5, one end of the folding arm 2 is opened around the connecting head 1, and the other end is in abutment with the end of the drainage hole 5, that is, the grate assembly 4 is buckled and fixed at the end of the drainage hole 5, and the leachate in the garbage pit flows into the drainage hole through the gap between adjacent folding arms 2, which can effectively prevent the garbage 6 from entering the drainage hole 5 to cause blockage, and can maintain a longer blocking effect and will not fail easily; when the grate assembly 4 is damaged, a new grate can be directly arranged in the original way, the new grate pushes the old grate, and the old grate is mixed into the garbage 6 and burned together, realizing easy maintenance and quick replacement.

[0032] As shown in Figure 2 and Figure 7 , the connecting head 1 and the folding arm 2 are provided with mounting holes, and a pin shaft 12 is inserted into the mounting hole to realize the hinge connection of the connecting head 1 and the folding arm 2, which is simple in structure and firm in connection, and the connecting head 1 and the folding arm 2 are designed in a foldable and retractable structure, which can be arranged from the outside of the garbage pit to the inlet of the drainage hole 5 inside the garbage pit through the narrow outlet end of the drainage hole 5, which is convenient and fast. Further, the folding arm 2 is three, and the included angle between adjacent folding arms 2 is 120°, which is convenient for the flow of leachate and can effectively block the garbage 6.

[0033] As shown in Figure 1 , Figure 5 and Figure 6 , the inside of the folding arm 2 is provided with a limiting reinforcing rib 21. When the grate assembly 4 is installed, the end of the installation rod 3 abuts against the limiting reinforcing rib 21 to push the grate assembly 4 to move in the drainage hole 5. When the installation of the grate assembly 4 is completed, the limiting reinforcing rib 21 abuts against the inner side wall of the end of the drainage hole 5, and the end of the folding arm 2 abuts against the outer side wall of the end of the drainage hole 5, so as to realize the stable installation of the grate assembly 4 at the water inlet of the drainage hole 5.

[0034] In this embodiment, the limiting reinforcing rib 21 can prevent the folding arm 2 from being broken due to the extrusion of the garbage 6, and the limiting reinforcing rib 21 abuts against the inner wall surface of the drainage hole 5, which can also prevent the folding arm 2 from being excessively opened. As shown in Figure 6 , after installation, the grate assembly 4 is buckled on the drainage hole 5 to prevent the garbage 6 from entering the drainage hole 5 and blocking the drainage hole 5, and the leachate in the garbage 6 can enter the drainage hole 5 through the space left between adjacent folding arms 2 (as shown by the arrow in Figure 6 ) and then be discharged.

[0035] As shown in Figure 1 and Figure 3As shown in the drawings, the end of the limiting reinforcing rib 21 is provided with a stepped surface 22, the end of the mounting rod 3 is provided with a boss 31, the stepped surface 22 is matched with the boss 31, so as to facilitate the mounting rod 3 to push the screen assembly 4 to move in the drain hole 5.

[0036] As shown in the drawings, Figure 3 The boss 31 is in a gradually changing arc structure. The mounting rod 3 is rotated to realize that the boss 31 pushes the folding arm 2 to open through the stepped surface 22.

[0037] As shown in the drawings, Figure 4 and Figure 5 The mounting rod 3 is further provided with a limiting rod 32, the limiting rod 32 is away from the boss 31, so as to limit the length of the mounting rod 3 to extend in the drain hole 5. The process of arranging the screen assembly 4 by using the mounting rod 3 can dredge the drain hole 5 at the same time, and the fixed limiting effect of the limiting rod 32 can also avoid that the mounting rod 3 is too deeply extended in the drain hole 5 to make the screen assembly 4 directly fall into the garbage pit.

[0038] In the embodiment, as shown in the drawings, Figure 5 and Figure 6 The screen assembly 4 can be put into the drain hole 5 after being folded, at this time, one end of the mounting rod 3 is on the limiting reinforcing rib 21 and is just at the low position of the boss 31, after the mounting rod 3 pushes the screen assembly 4 to the mounting position, the limiting rod 32 is just on the wall of the garbage pit, preventing the mounting rod 3 from being too deeply extended to cause the screen assembly 4 to fall off from the inside of the garbage pit. At this time, the screen assembly 4 has come out of the entrance of the drain hole 5 and is no longer limited by the inner wall of the drain hole 5, the mounting rod 3 is rotated clockwise from the outside of the garbage pit, the screen assembly 4 will not rotate due to the resistance of the garbage, therefore, the boss 31 will gradually squeeze and open the folding arm 2, the mounting rod 3 is taken out, and the installation is completed. The screen assembly 4 will not generally fall off from the inside of the garbage pit due to the squeezing of the garbage 6 in the garbage pit and the support of the limiting reinforcing rib 21.

[0039] When the screen assembly 4 is damaged or falls off due to the lack of garbage in the garbage pit, the above steps are repeated to squeeze the old screen assembly 4 with the new screen assembly 4 to realize replacement, and the old screen assembly 4 is incinerated with the garbage.
