Description

Technical Field

[0001] The utility model relates to the cross-disciplinary technical field of mechanical filtration and aerodynamics, and in particular to a garbage bin sewage drainage air-powered automatic clearing and blocking drainage grille door device. Background Art

[0002] The existing domestic waste incineration plant projects have multiple drainage holes at the bottom of the concrete pool wall on one side of the garbage bin, and simple iron fence filter screens or copper plate perforated filter screens are arranged in the drainage holes. There is an underground maintenance ditch about 6 meters behind the filter screen. When domestic waste is piled up in the garbage bin, the leachate sewage will continue to seep out of the domestic waste, and after being filtered by the simple filter screen in the drainage holes of the garbage bin, it will be discharged into the drainage collection ditch between the ditches, and then it will flow into the collection pool by gravity, and finally it will be pumped away by a water pump for harmless treatment.

[0003] Considering that the garbage bin is about 29 meters deep, domestic garbage has been piled up in front of the drainage holes of the garbage bin for a long time. The leachate sewage seeps into the drainage holes and flows through the simple filter net in the drainage holes to the leachate collection ditch. However, due to the complex composition of domestic garbage, combined with the operation and management characteristics of the garbage bin and the arc-shaped grab structure of the garbage grab, a part of the garbage piled up in front of the drainage holes cannot be thoroughly cleaned for a long time, and will soon accumulate and block the drainage holes, and the leachate sewage will not be able to flow through the simple filter net in the drainage holes; in addition, since the simple filter net has been buried deep with domestic garbage for a long time, the drainage holes of the simple filter net will soon be blocked by garbage, and finally the leachate sewage in the garbage bin cannot be discharged; when the garbage bin When the leachate and sewage in the garbage bin cannot be discharged in time, the water level in the garbage bin will continue to rise, and the water level in the garbage bin often exceeds 4 to 10 meters deep, which will make it difficult to stack and dump materials in the garbage bin, and the fermentation of domestic garbage will be difficult and the fermentation time will be prolonged. The amount of domestic garbage used for combustion will be greatly reduced or it will be incinerated with water, which will greatly increase the difficulty of operating the entire plant and the load of the garbage grab bucket will be greatly increased, resulting in a significant decline in the economic benefits of the entire plant and a significant increase in safety and environmental risks. In order to discharge the leachate and sewage in the garbage bin in time and effectively lower the water level in the garbage bin, workers have to be frequently dispatched to the channel room where there are a large amount of toxic, harmful and flammable and explosive gases to manually clean the simple filter net to lower the water level of the leachate and sewage in the garbage bin.

[0004] Therefore, based on the above technical problems, technicians in this field urgently need to develop a garbage bin sewage drainage air-powered automatic clearing and blocking drainage grille door device. Utility Model Content

[0071] Specifically, the present embodiment discloses a garbage bin sewage drainage air automatic clearing drainage grille door device, the grille door device includes a grille door body 1, a compressed air tank 2, and a venturi nozzle group connected to the compressed air tank 2 and arranged in the drainage area of ​​the grille door body 1; the device of the present embodiment cooperates with the drainage hole of the garbage bin pool wall through the grille door body 1 and is installed at the drainage hole of the garbage bin pool wall, and forms two drainage areas, an upper drainage area and a lower drainage area, through the grille door body 1, and cuts a plurality of drainage slits through a square pipe, the drainage slits are used to discharge sewage, and the drainage area of ​​the present embodiment is correspondingly provided with a sealing steel plate, which is movably connected, so that the corresponding drainage slit can be selected to be closed or opened according to actual process requirements. The venturi nozzle group of the present embodiment is connected to the compressed air tank 2, and the switch of the corresponding pipeline is controlled by an electromagnetic pulse valve to control the corresponding venturi nozzle group to spray compressed air into the garbage bin to break the accumulated garbage in the area.

[0072] Preferably, the grille door body 1 of this embodiment is welded by square tubes to form an outer frame structure;

[0073] A square tube is transversely arranged inside the outer frame structure to divide the inner area of ​​the outer frame structure into an upper drainage area and a lower drainage area;

[0074] The upper drainage area and the lower drainage area are divided into multiple drainage slits by multiple square tubes extending in the vertical direction, and the width of the drainage slit is 20mm;

[0075] The grille door body 1 is symmetrically provided with side wall-attached steel plates 102 at the side of the upper drainage area, and the grille door body 1 is provided with a top wall-attached steel plate 101 at the top;

[0076] The grille door body 1 is attached to and fixed to the garbage bin wall through three wall-mounted steel plates;

[0077] The grille door body 1 is provided with four long screws 103, through which the three wall-mounted steel plates are fixed to the garbage bin wall and fastened by square nuts 104;

[0078] A transversely extending supporting and fixing square tube 105 is provided at one end of the long screw rod 103 away from the grille door body 1 .

[0079] This embodiment further defines the structure of the grille door body 1. The grille door body 1 of this embodiment is formed by welding large-size square tubes to form an outer frame structure. At the same time, in order to form the upper drainage area and the lower drainage area mentioned above, it is also formed by welding multiple square tubes. In each drainage area, small-size square tubes are arranged at intervals to form a drainage gap with a width of 20 mm. The grille door body 1 of this embodiment is attached to the garbage bin pool wall through two side wall-attached steel plates 102 and a top wall-attached steel plate 101, and is fixed by four long screws 103. The components of this embodiment can be assembled by fasteners such as bolts 8.

[0080] In addition, the upper drainage area and the lower drainage area of ​​the present embodiment are both provided with sealing steel plates, and the sealing steel plates of the present embodiment are structures with a size that can block the drainage slits. At the same time, in order to meet different process requirements, the sealing steel plates can be designed to be able to slide laterally, and the sealing steel plates can be selected to block the corresponding drainage slits, or to open all the drainage slits, or to close all the drainage slits. Since there are many structures that can achieve the sliding or flipping of the sealing steel plates, which are relatively common in the mechanical field, this part is not the main design point of this application and will not be repeated.

[0081] During operation, the drainage gap can be closed to prevent the Venturi nozzle from spraying a large amount of air into the garbage bin, causing small garbage and debris to be sprayed from the drainage gap to one side of the ditch, causing the leachate drainage ditch to be blocked by debris.

[0082] In order to realize the assembly and fixation of the compressed air tank 2 , the grille door body 1 of this embodiment is connected with two angle steel brackets 201 , and the end of the angle steel bracket 201 far from the grille door body 1 is connected to the compressed air tank 2 to support the compressed air tank 2 .

[0083] Preferably, the compressed air tank 2 of this embodiment has an upper outlet and a lower outlet;

[0084] The upper outlet of the compressed air tank 2 is connected to the upper venturi nozzle group 5 through the upper pipeline structure 3 to deliver compressed air to the upper venturi nozzle group 5;

[0085] The lower outlet of the compressed air tank 2 is communicated with the lower venturi nozzle group 6 through the lower pipeline structure 4 to deliver compressed air to the lower venturi nozzle group 6 .

[0086] Specifically, the upper pipeline structure 3 of this embodiment includes, from one end of the compressed air tank 2 to one end of the upper venturi nozzle group 5, the following:

[0087] The first upper 90° double-ended external thread short tube 301, the double-ended internal thread short joint 302, the first upper straight tube 303, the second upper straight tube 304, the upper pipeline flexible joint 305, the second upper 90° double-ended external thread short tube 306, and the cross assembly;

[0088] The four-way assembly is connected to the upper venturi nozzle group 5;

[0089] An upper electromagnetic pulse valve 202 is installed at the connection between the upper first straight pipe 303 and the upper second straight pipe 304, and the upper electromagnetic pulse valve 202 is used to control the switch of the upper pipeline structure 3;

[0090] The lower pipeline structure 4 includes the following from one end of the compressed air tank 2 to one end of the lower venturi nozzle group 6:

[0091] 45° double-ended outer thread short tube 401, lower first straight tube 402, lower pipeline flexible joint 403, 45° inner and outer thread interface elbow 404, lower second straight tube 405, and a four-way assembly;

[0092] The four-way assembly is connected to the lower venturi nozzle group 6;

[0093] A lower electromagnetic pulse valve 203 is installed at the connection between the 45° double-ended outer thread short tube 401 and the lower first straight tube 402 , and the lower electromagnetic pulse valve 203 is used to control the switch of the lower pipeline structure 4 .

[0094] More specifically, in order to synchronously control the operation of each group of the venturi nozzle group, the present embodiment uses a four-way assembly to connect the venturi nozzle group and the compressed air tank 2. The four-way assembly of the present embodiment includes:

[0095] Cross joint 701; and

[0096] A middle straight pipe joint 702 and two side straight pipe joints 703 respectively connected to the four-way joint 701;

[0097] The four-way assembly is connected to the corresponding Venturi nozzle group through the middle straight pipe joint 702 and the side straight pipe joint 703.

[0098] The venturi nozzle assembly of this embodiment includes:

[0099] An intermediate venturi nozzle 601 located in the middle position; and

[0100] Side Venturi nozzles 602 arranged symmetrically on both sides;

[0101] The specifications of the side venturi nozzle 602 are smaller than those of the middle venturi nozzle 601 .

[0102] The device of this embodiment can be operated by the upper venturi nozzle group 5 or the lower venturi nozzle group 6 according to the location of the accumulated debris to be destroyed. The upper venturi nozzle group 5 is used to destroy the accumulated debris in the garbage bin as an example for further explanation:

[0103] When the upper electromagnetic pulse valve 202 of the compressed air tank 2 is opened, the upper electromagnetic pulse valve 202 is opened instantaneously, and the compressed air flows from the upper outlet of the compressed air tank 2 through the upper first 90° double-ended external thread short tube 301, the double-ended internal thread short joint 302, the upper first straight tube 303, the upper second straight tube 304, the upper pipeline flexible joint 305, the upper second 90° double-ended external thread short tube 306, and the four-way assembly, and finally reaches the upper venturi nozzle group 5. At this time, the upper venturi nozzle group 5 sprays instantaneously. At the same time, the venturi nozzle absorbs the air around the nozzle and enters the garbage bin together, impacting, spraying, crushing and stirring the accumulated domestic garbage on the front side of the grille door body 1, so that the leachate in the garbage bin flows smoothly to the front of the grille door body, and flows out through the trumpet pipes of the middle venturi nozzle 601 and the side venturi nozzle 602 to the leachate collection ditch of the garbage bin, and then transported out.

[0104] Similarly, the working principle of the lower venturi nozzle group 6 is the same as that of the upper part, and the operation of the venturi nozzle groups at different positions can be controlled by simply opening different electromagnetic pulse valves of the compressed air tank 2.

[0105] As an extended implementation method, the device of this embodiment can adapt to changes in the size of the hole by increasing or decreasing the number of upper and lower venturi nozzles, the capacity of the compressed air tank 2, and the size of the grille door body 1 according to the different hole sizes reserved in the garbage bin of the application project, and achieve the effect of the upper and lower venturi nozzles on the impact, explosion, crushing and stirring of the garbage accumulated in the garbage bin, thereby ensuring the discharge effect of leachate sewage.

[0106] In the above technical solution, the utility model provides a garbage bin sewage drainage air can automatically clear the drainage grille door device, which has the following beneficial effects:

[0107] The grille door device of the utility model uses six Venturi nozzles arranged in the drainage area to utilize the instant when the electromagnetic pulse valve of the compressed air tank is opened to form strong compressed air impact energy, which rushes out of the nozzle of the Venturi nozzle and absorbs the air around the nozzle to impact, explode, break and loosen the garbage and debris accumulated in front of the grille door, so that the leachate and sewage in the garbage bin can flow smoothly to the front of the device, and finally flow out of the garbage bin through the drainage gap and the trumpet pipe in front of the Venturi nozzle.

[0108] The grille door device of the utility model uses two groups of Venturi nozzle groups to spray garbage accumulated at different heights, thereby effectively solving the problem of blockage caused by garbage and debris accumulated at the bottom of the garbage bin in front of the device. At the same time, in the process of compressed air blowing, the debris in the trumpet pipe through which the leachate flows is also blown clean, ensuring the smooth flow of the leachate discharge channel. No manual cleaning is required, which greatly reduces the labor intensity, and especially avoids the workers from frequently cleaning simple filter screens in channels with toxic and harmful, flammable and explosive gas spaces, thus avoiding high-risk operations such as worker poisoning and explosions in confined spaces.

[0109] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
