[0044] Example 1

[0045] like Figure 1-6As shown, an embodiment of the present invention provides a domestic garbage pool sewage discharge device, comprising a leachate pool 10 and a garbage pool 20 installed on the ground, the leachate pool 10 and the garbage pool 20 are connected through a sewage pipe 30, the garbage pool 20 comprises a pool body 21 with a closed lower end and an open upper end, and a closing cover 40 for opening and closing the opening is rotatably provided on the top of the pool body 21, the leachate pool 10 is used to collect and process the leachate discharged from the garbage pool 20; a garbage platform 50 for holding garbage is slidably arranged in the pool body 21 along the vertical direction, and is provided with a plurality of leakage holes for allowing the sewage in the garbage to pass through, so that the sewage in the garbage can flow into the pool bottom through these holes and be discharged into the leachate pool 10 through the sewage pipe 30, and the garbage platform 50 is provided with a lifting component 60 running through it; a squeezing mechanism 70, comprising a lifting component 60 rotatably arranged along its axial direction The bidirectional screw 71 of the garbage table 50 and the two extrusion plates 72 threadedly connected to the bidirectional screw 71 on opposite sides are connected to the lifting assembly 60; wherein the closing cover 40 is rotated to have an open state and a closed state; when the closing cover 40 is rotated to the open state, the garbage table 50 is driven to move upward in the pool body 21 through the linkage assembly 80, and at the same time, the bidirectional screw 71 is driven to rotate through the lifting assembly 60 to drive the two extrusion plates 72 to move away from each other; when the closing cover 40 is rotated to the closed state, the garbage table 50 is driven to move downward in the pool body 21 through the linkage assembly 80, and at the same time, the bidirectional screw 71 is driven to rotate in the opposite direction through the lifting assembly 60 to drive the two extrusion plates 72 to move towards each other to squeeze the garbage, so as to compress the volume of the garbage and squeeze out the moisture in the garbage.

[0046] In the embodiment of the present invention, when the closing cover 40 is in the closed state, the garbage platform 50 is located at the bottom of the pool body 21, and the two extrusion plates 72 are in opposite positions, compressing the garbage, reducing the volume of the garbage and squeezing out the water; when the closing cover 40 is rotated to the open state, the linkage assembly 80 drives the garbage platform 50 to move upward. At the same time, the lifting assembly 60 is started, so that the bidirectional screw 71 rotates clockwise to drive the two extrusion plates 72 to move in opposite directions, releasing the compressed garbage. During the rising process of the garbage platform 50, the water in the garbage continues to flow into the bottom of the pool through the leakage hole, and is discharged into the leachate pool 10 through the sewage pipe 30; when the closing cover 40 is rotated to the closed state, the linkage assembly 80 drives the garbage platform 50 to move downward. At the same time, the lifting assembly 60 is started in the reverse direction, so that the bidirectional screw 71 rotates counterclockwise to drive the two extrusion plates 72 to move in opposite directions, and compress the garbage again. During the compression process, the water in the garbage is further squeezed out, so that it flows into the pool bottom through the leakage hole and is discharged into the leachate pool 10 through the sewage pipe 30, so as to separate the solid and liquid of the garbage inside the pool body 21, and prevent the garbage from being soaked in liquid for a long time to produce a lot of odor.

[0047] Specifically, Figure 3-5 As shown, in an embodiment of the present invention, the lifting assembly 60 includes a vertically arranged tooth plate 61 and a toothed disc 62 rotatably arranged on the garbage platform 50 and meshing with the toothed disc 61 for transmission, one end of the toothed disc 62 is coaxially connected to one end of the bidirectional screw 71; the garbage platform 50 is provided with a guide sleeve 63, one end of the toothed plate 61 is arranged on the pool body 21, and the other end passes through the garbage platform 50 and the guide sleeve 63, wherein two guide sleeves 63 are provided, and are respectively arranged at the upper and lower ends of the garbage platform 50 to limit the toothed plate 61, and in order to better make the garbage platform 50 move up and down more smoothly, the lifting assembly 60 can be set to two groups, which are respectively located on both sides of the garbage platform 50.

[0048] Specifically, the rotation of the bidirectional screw 71 is achieved through the meshing transmission of the tooth plate 61 and the tooth disc 62, thereby controlling the movement of the extrusion plate 72. That is, during the descent of the garbage platform 50, the tooth plate 61 moves downward relative to the tooth disc 62. Due to the meshing of the tooth plate 61 and the tooth disc 62, the tooth disc 62 will rotate counterclockwise, thereby driving the bidirectional screw 71 to rotate counterclockwise. The rotation of the bidirectional screw 71 drives the two extrusion plates 72 to move toward each other, compressing the garbage again to squeeze out the moisture in the garbage, so that it flows into the pool bottom through the leakage hole and is discharged into the leachate pool 10 through the sewage pipe 30.

[0049] Based on the above scheme, Figure 4 As shown, in an embodiment of the present invention, the garbage platform 50 is provided with a limiting slider 51, and the tooth plate 61 is provided with a limiting groove 611 corresponding to the limiting slider 51, and the limiting slider 51 is slidably arranged in the limiting groove 611 to improve the stability of the garbage platform 50 during the lifting process.

[0050] Specifically, Figure 3 As shown, in an embodiment of the present invention, the linkage assembly 80 includes a first gear 81, a second gear 82, a screw rod 87 and a reversing assembly 90; the first gear 81 is rotatably arranged on the closing cover 40 and is transmission-connected to the second gear 82; a screw hole is vertically opened on the garbage table 50, and the screw rod 87 is rotationally connected to the bottom of the pool body 21 and is threadedly connected to the screw hole. The reversing assembly 90 is arranged on the pool body 21 and is connected to the second gear 82 to convert the rotation of the screw rod 87 into power for lifting and lowering the garbage table 50. The linkage between the rotation of the closing cover 40 and the lifting and lowering of the garbage table 50 is realized through gear transmission, the screw rod 87 and the reversing assembly 90.

[0051] Specifically, when the closing cover 40 rotates to the open state, the first gear 81 rotates accordingly, and the first gear 81 drives the second gear 82 to rotate, and the second gear 82 transmits the rotation to the screw rod 87 through the reversing assembly 90. When the screw rod 87 rotates, due to its threaded connection with the screw hole on the garbage table 50, the garbage table 50 starts to move upward; when the closing cover 40 rotates to the closed state, the first gear 81 rotates in the opposite direction, and the first gear 81 drives the second gear 82 to rotate in the opposite direction, and the second gear 82 transmits the rotation to the screw rod 87 through the reversing assembly 90. When the screw rod 87 rotates in the opposite direction, the garbage table 50 starts to move downward.

[0052] Specifically, Figure 6 As shown, in an embodiment of the present invention, the reversing assembly 90 includes a turbine 91 and a worm 92, the worm 92 is connected to the bottom of the pool body 21 by rotating along its axial direction, and the axis of the worm 92 is perpendicular to the axis of the screw 87, the turbine 91 is coaxially fixedly connected to the screw 87, and the turbine 91 is meshed with the worm 92, the existence of the turbine 91 and the worm 92 not only realizes the direction conversion of power transmission, but also has a self-locking function.

[0053] Specifically, when the closing cover 40 rotates to the open state, the first gear 81 rotates accordingly, and the first gear 81 drives the second gear 82 to rotate, and the second gear 82 transmits the rotation to the screw rod 87 through the reversing assembly 90. When the screw rod 87 rotates, since it is threadedly connected to the screw hole on the garbage table 50, the garbage table 50 starts to move upward; when the closing cover 40 rotates to the closed state, the first gear 81 rotates in the opposite direction, and the first gear 81 drives the second gear 82 to rotate in the opposite direction, and the second gear 82 transmits the rotation to the turbine 91 through the worm 92. The reverse rotation of the worm 92 causes the turbine 91 meshing with it to rotate in the opposite direction, thereby driving the screw rod 87 to rotate in the opposite direction. When the screw rod 87 rotates in the opposite direction, the garbage table 50 starts to move downward.

[0054] Specifically, Figure 3As shown, in the embodiment of the present invention, the first gear 81 is connected to the third gear 83 through the first toothed belt 85, the toothed roller of the third gear 83 is coaxially fixedly connected to the fourth gear 84, the fourth gear 84 is connected to the second gear 82 through the second toothed belt 86, and the toothed roller of the third gear 83 is rotatably arranged on the top of the pool body 21; when the closing cover 40 is rotated to the open state, the first gear 81 rotates accordingly, the first gear 81 drives the third gear 83 to rotate through the first toothed belt 85, and the toothed roller of the third gear 83 is coaxially fixedly connected to the fourth gear 84. 4 also rotates accordingly, the fourth gear 84 drives the second gear 82 to rotate through the second toothed belt 86, and the second gear 82 transmits the rotation to the turbine 91 through the reversing assembly 90; when the closing cover 40 rotates to the closed state, the first gear 81 rotates in the opposite direction, the first gear 81 drives the third gear 83 to rotate in the opposite direction through the first toothed belt 85, and the fourth gear 84 coaxially fixedly connected with the gear roller of the third gear 83 also rotates in the opposite direction, the fourth gear 84 drives the second gear 82 to rotate in the opposite direction through the second toothed belt 86, and the second gear 82 transmits the rotation to the turbine 91 through the reversing assembly 90.

[0055] Specifically, Figure 6 As shown, in an embodiment of the present invention, the closing cover 40 is provided with a rotating shaft, one end of the rotating shaft is coaxially connected to the first gear 81, and the other end is connected to the output end of the driving motor 41, and the driving motor 41 is arranged at the top of the pool body 21. The driving motor 41 realizes the automatic opening and closing of the closing cover 40 without manual operation, thereby improving the degree of automation.

[0056] Specifically, Figure 2 As shown, in the embodiment of the present invention, the middle end of the bottom of the pool body 21 is an arc-shaped structure, and drainage ditches 22 are arranged on both sides of the pool body 21. The arc-shaped structure allows the sewage in the garbage to naturally flow into the drainage ditches 22 on both sides, and the drainage ditches 22 on both sides can quickly guide the sewage into the leachate pool 10, thereby improving the drainage efficiency; a suction groove 11 is arranged on one side of the bottom of the leachate pool 10, and the sewage pipe 30 is connected to the drainage groove 22 and the suction groove 11 respectively.

[0057] Specifically, Figure 2 As shown, in this embodiment of the present invention, the height of one end of the sewage pipe 30 connected to the sewage ditch 22 is greater than the height connected to the sewage suction ditch 11, so that the sewage from the garbage can flow smoothly from the garbage pool 20 into the leachate pool 10.

[0058] Example 2

[0059] like Figure 1-2As shown, an embodiment of the present invention provides a construction method of a domestic garbage pool sewage discharge device, including the domestic garbage pool sewage discharge device as described in Example 1, and the construction method includes the following steps:

[0060] Step 1: digging grooves on the ground to accommodate the leachate pool 10 and the garbage pool 20 respectively;

[0061] Step 2: Then, a sewage pipe 30 is pre-buried at the bottom of the groove, and a waterproof sealing treatment is performed on the circumference of the sewage pipe 30;

[0062] Specifically, the waterproof sealing treatment should use high-quality sealing materials, such as rubber sealing rings, waterproof glue, etc., to ensure that there is no leakage at the joints, and when the outer concrete is constructed, the concrete mix ratio and pouring process should be strictly controlled to ensure the density and uniformity of the concrete layer, so that it can effectively protect the sewage pipe 30;

[0063] The diameter of the sewage pipe 30 needs to be determined according to the size and burial depth of the garbage pool 20, and the diameter is required to be ≥1000mm. Such a large diameter design can effectively ensure the smooth discharge of sewage and avoid blockage. At the same time, a comprehensive assessment should be conducted based on factors such as the amount of sewage expected to be generated by the garbage pool 20 and the frequency of discharge. For example, if the garbage pool 20 is large in scale and the garbage has a high water content, the amount of sewage generated is large, then the diameter of the pipe needs to be appropriately increased to ensure that the sewage can be discharged in a timely and smooth manner, and the waterproof sealing treatment around the sewage pipe 30 is required.

[0064] Step 3, then construct the bottom plates of the leachate pool 10 and the garbage pool 20 respectively, then install the leachate pool 10 and the garbage pool 20 in the groove, and connect the two ends of the sewage pipe 30 respectively, and after the construction of the galvanized sewage pipe 30 is completed, apply an anti-corrosion and waterproof layer on the inner side of the pipe wall in the same manner as the garbage pool 20 and the leachate pool 10 pool wall. The anti-corrosion and waterproof layer can effectively resist the erosion of the sewage from the garbage pool 20 to the sewage pipe 30, thereby extending the service life of the sewage pipe 30;

[0065] Specifically, when applying the anti-corrosion and waterproof layer on the inner side of the pipe wall, it is necessary to ensure that the thickness of the coating is uniform and meets the design requirements. A multi-layer coating method can be used. After each layer is applied, wait for a certain period of time for it to dry and solidify before applying the next layer. As for the special maintenance of the anti-corrosion and waterproof layer, in addition to regularly checking the integrity of the coating, the monitoring of the sewage pipe 30 can be strengthened in the early stage of the garbage pool 20 being put into use, such as regularly checking the pressure and flow in the sewage pipe 30 and whether there are signs of leakage. If the coating is found to be slightly damaged, it can be repaired in time, using the same materials and processes as the original coating to ensure that the sewage pipe 30 is always in a good protective state, ensuring that the sewage from the domestic garbage pool 20 can be discharged to the leachate pool 10 in a long-term, stable and safe manner, maintaining the normal operation of the entire garbage treatment system, and reducing the potential risk of pollution to the environment. At the same time, it can also reduce the maintenance cost and risk of operational interruption caused by failure of the sewage pipe 30, and improve the overall reliability and sustainability of garbage treatment facilities;

[0066] Among them, during the casting process of the raft slab of the leachate pool 10, it is necessary to ensure that the sewage pipe 30 is accurately anchored into the raft slab and firmly fixed. When carrying out anti-floating reinforcement, anti-floating anchor rods, anti-floating piles, etc. can be used, and appropriate anti-floating measures can be selected according to factors such as the geological conditions and groundwater level of the leachate pool 10. The anti-floating anchor rod can connect the sewage pipe 30 to a stable stratum, and resist the buoyancy of groundwater through the friction and anchoring force of the anchor rod; the anti-floating pile balances the buoyancy through the bearing capacity of the pile body. When temporarily blocking the sewage pipe 30, special blocking materials such as foam plastic plugs, rubber plugs, etc. can be used, and they should be marked so that the blockage can be easily removed after the subsequent construction is completed;

[0067] When constructing the bottom plate of the garbage pool 20, the sewage pipe 30 must be laid and fixed in strict accordance with the design requirements. To avoid disturbance of the sewage pipe 30, warning signs can be set up at the construction site to limit the range of activities of construction machinery and personnel near the sewage pipe 30. When using angle steel to temporarily fix the sewage pipe 30, the specifications and quantity of the angle steel should be reasonably selected according to the diameter and length of the sewage pipe 30 to ensure that the angle steel can provide sufficient support. For example, for a sewage pipe 30 with a larger diameter, thicker and larger angle steel can be selected and fixed at multiple locations of the sewage pipe 30, such as setting an angle steel fixing bracket at a certain interval.

[0068] In the embodiment of the present invention, the lower part of the sewage pipe 30 is also filled with a filter material layer 31. The filter material layer 31 is provided to play the role of air isolation and pressure isolation, so that the air pressure on one side of the garbage pool 20 is not affected by the leachate pool 10, and the harmful gas in the leachate pool 10 and the pressure fluctuation caused by the liquid level difference can be prevented from being transmitted to the garbage pool 20, thereby maintaining the relative stability of the air pressure in the garbage pool 20, and avoiding the abnormal flow or splashing of garbage and sewage in the garbage pool 20 due to the change of air pressure; secondly, the filter material layer 31 can also play a preliminary filtration role for the discharged sewage. The function is to intercept larger granular impurities in the sewage and prevent them from entering the leachate pool 10 and causing adverse effects on the subsequent treatment process of the leachate pool 10, such as avoiding clogging the drainage pipe of the leachate pool 10 or affecting the normal operation of the leachate treatment equipment; the selection of the filter layer 31 needs to comprehensively consider factors such as its filtering effect, air permeability and durability. Materials such as gravel and activated carbon can be selected. Gravel can provide good support and filtering pores, and activated carbon has advantages in adsorbing odors and some organic pollutants. The combination of the two can achieve better results.

[0069] In the embodiment of the present invention, the sewage pipe 30 is a galvanized sewage pipe 30 , which has good corrosion resistance and strength and can adapt to the harsh environment of sewage discharge in the garbage pool 20 .

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than as a barrier. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
