Description

Technical Field

[0001] This utility model relates to the field of drainage pipe technology for storage pits, specifically an automatic drainage device for kitchen waste storage pits. Background Technology

[0002] Kitchen waste is transported to the waste treatment plant by transport vehicles. To ensure the continuity of production, the materials need to be stored in the material pit. However, the materials have a high water content, and the materials placed in the material pit will also naturally ferment and produce water. Since the organic materials of kitchen waste are fermented by dry anaerobic digestion, the water content of the materials needs to be controlled to a certain extent. Therefore, it is necessary to drain the water in the material pit.

[0003] Currently, drainage pipes are installed on the retaining walls on the sides of the storage pit to drain the accumulated water into an external sewage tank for further treatment. Because the storage pit is located in a low-lying area, the drainage system is designed at the bottom of the pit (usually the basement of the food waste processing plant). When the drainage pipes are in operation, large pieces of food waste in the storage pit can easily clog the drain outlets. This requires workers to descend to the lower level to operate, which not only poses safety risks but also increases the workers' workload. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automatic drainage device for kitchen waste storage pits, which allows workers to automatically drain the storage pit without entering the operating room.

[0005] This utility model provides the following technical solution: an automatic drainage device for a kitchen waste storage pit, comprising a support platform installed on one side of several drainage pipes of the storage pit body, a front plate and a rear plate fixedly connected to the upper surface of the support platform, a moving component provided between the front plate and the rear plate, a power mechanism connected to the upper surface of the support platform, the output end of the power mechanism passing through the front plate, the moving component and the rear plate, the end of the moving component away from the power mechanism passing through the rear plate and connected to several adjusting rods, the bottom surface of the other end of the several adjusting rods is provided with an inclined surface, the outer wall of the several adjusting rods is slidably connected to the inner wall of the several drainage pipes respectively, and the inner wall of the several inclined surfaces is also slidably connected to the inner wall of the several drainage pipes respectively.

[0006] Furthermore, the power mechanism includes a drive mechanism and a lead screw. The outer wall of the drive mechanism is fixedly connected to the upper surface of the support platform. The output end of the drive mechanism is fixedly connected to one end of the lead screw. The other end of the lead screw passes through the front plate, the moving component, and the rear plate. The outer wall of the lead screw is rotatably connected to the inner walls of both the front plate and the rear plate.

[0007] Furthermore, the moving assembly includes a moving plate, a push plate, and several slide rods. The middle part of the moving plate is sleeved and threadedly connected to the outer wall of the lead screw. Both ends of the moving plate are respectively sleeved and fixedly connected to the outer walls of several slide rods. The other ends of several slide rods all penetrate the rear plate and are fixedly connected to the side wall of the push plate. The other side of the push plate is fixedly connected to the end of several adjusting rods away from the inclined plane. The bottom surface of the moving plate is slidably connected to the upper surface of the support platform.

[0008] Furthermore, a liquid collection tank is fixedly connected to the side of the support platform near the storage pit body, and the side of the liquid collection tank away from the support platform is fixedly connected to the side wall of the storage pit body. A drain port is opened on the side of the liquid collection tank away from the support platform and the storage pit body, and the push plate and several adjusting rods are located inside the drain port.

[0009] Furthermore, several adjusting rods and several drain pipes are arranged in parallel and distributed at equal intervals.

[0010] Furthermore, the adjustment rods are divided into multiple rows, and the inclination angle of the inclined surface of each row of adjustment rods is different.

[0011] Furthermore, the slope of the multi-row adjusting rods increases from top to bottom.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This automatic drainage device for kitchen waste storage pits is provided by setting a support platform on one side of the drainage pipe of the storage pit body, and setting a power mechanism, a moving component, a front plate and a rear plate on the support platform. Several adjusting rods are connected through the moving component. When the connection between the storage pit body and the drainage pipe is blocked by kitchen waste during the drainage process, the moving component and adjusting rods can be moved by the power mechanism to deal with the connection and make subsequent drainage smooth.

[0014] 2. This automatic drainage device for kitchen waste storage pits can adjust the drainage flow rate inside the drainage pipe in a timely manner according to the sewage situation inside the storage pit, by opening an inclined surface on the adjusting rod, so as to reduce the load on the external sewage tank.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1-4 An automatic drainage device for a kitchen waste storage pit includes a support platform 3 installed on one side of several drain pipes 2 in the storage pit body 1. A front plate 4 and a rear plate 5 are fixedly connected to the upper surface of the support platform 3. A moving component is provided between the front plate 4 and the rear plate 5. A power mechanism is also connected to the upper surface of the support platform 3. The output end of the power mechanism passes through the front plate 4, the moving component and the rear plate 5. The end of the moving component away from the power mechanism passes through the rear plate 5 and is connected to several adjusting rods 11. The bottom surface of the other end of the several adjusting rods 11 is provided with an inclined surface 111. The outer wall of the several adjusting rods 11 is slidably connected to the inner wall of the several drain pipes 2 respectively, and the inner wall of the several inclined surfaces 111 is also slidably connected to the inner wall of the several drain pipes 2 respectively.

[0022] like Figures 1 to 4 As shown, when the automatic drainage device for the kitchen waste storage pit of this utility model is in use, the kitchen waste is first put into the opening above the storage pit body 1. Then, the kitchen waste will generate liquid inside the storage pit body 1. The liquid can be discharged to the outside of the storage pit body 1 through several drainage pipes 2 on one side of the storage pit body 1.

[0023] During the leachate discharge process, the kitchen waste inside the storage pit body 1 may block the drain pipe 2. At this time, the power mechanism located on the support platform 3 is activated by the external controller. The power mechanism moves the moving component and pushes several adjusting rods 11 into several drain pipes 2 respectively. Then, as the adjusting rods 11 continue to extend, they enter the storage pit body 1 and push away the kitchen waste blocking the connection between the storage pit body 1 and the drain pipe 2. Then, the power mechanism is reversed, and the adjusting rods 11 are pulled out from the storage pit body 1 and the drain pipe 2 by the moving component. During the return of the adjusting rods 11, the liquid inside the storage pit body 1 is no longer blocked and can continue to be discharged from the drain pipe 2.

[0024] Using the above method, the drainage outlet of the storage pit body 1 can be automatically treated without the need for manual operation, which is convenient, quick, and safe.

[0025] Furthermore, because different types of kitchen waste contain varying amounts of moisture, if the storage pit 1 contains a large amount of moisture, it may cause a large amount of leachate to rapidly flow into the external sewage tank through several drain pipes 2, increasing the load on the sewage tank and potentially causing overflow. In this case, several adjusting rods 11 can be inserted into different drain pipes 2 to change the inner wall size of the drain pipes 2, thereby controlling the flow rate of sewage from the storage pit 1 into the external sewage tank and keeping it within a reasonable range. The adjusting rods 11 are solid rods.

[0026] It should be noted that both the external controller and the external sewage tank are existing and mature technologies, and will not be described in detail here.

[0027] Please refer to the main text. Figures 1-4 The power mechanism includes a drive mechanism 6 and a lead screw 7. The outer wall of the drive mechanism 6 is fixedly connected to the upper surface of the support platform 3. The output end of the drive mechanism 6 is fixedly connected to one end of the lead screw 7. The other end of the lead screw 7 passes through the front plate 4, the moving component and the rear plate 5. The outer wall of the lead screw 7 is rotatably connected to the inner walls of the front plate 4 and the rear plate 5.

[0028] More specifically, the drive mechanism 6 includes a motor and a reducer. When it is necessary to control the movement of the adjusting rod 11, the motor can be turned on by an external controller. The output end of the motor can work with the reducer to rotate the lead screw 7. After the lead screw 7 rotates, it can move the moving component connected to the surface, thereby moving the adjusting rod 11 through the moving component.

[0029] Please refer to the main text. Figures 1-4 The moving assembly includes a moving plate 8, a push plate 10, and several slide rods 9. The middle part of the moving plate 8 is sleeved and threadedly connected to the outer wall of the lead screw 7. The two ends of the moving plate 8 are respectively sleeved and fixedly connected to the outer walls of several slide rods 9. The other ends of several slide rods 9 all pass through the rear plate 5 and are fixedly connected to the side wall of the push plate 10. The other side of the push plate 10 is fixedly connected to the end of several adjusting rods 11 away from the inclined surface 111. The bottom surface of the moving plate 8 is slidably connected to the upper surface of the support platform 3.

[0030] More specifically, because the bottom surface of the movable plate 8 rests against the support platform 3, it will not rotate. As the lead screw 7 rotates, it can move the movable plate 8, which is connected to the surface thread, laterally. When the movable plate 8 moves, it can move several sliding rods 9. Then, the sliding rods 9 can push the push plate 10 to move. After that, the push plate 10 can move back and forth with several adjusting rods 11, thereby clearing the blockage inside the adjusting rods 11 and adjusting and controlling the flow rate inside the drain pipe 2.

[0031] Please refer to the following: Figures 1-4 A liquid collection tank 12 is fixedly connected to the side of the support platform 3 near the storage pit body 1. The side of the liquid collection tank 12 away from the support platform 3 is fixedly connected to the side wall of the storage pit body 1. A drain port 121 is opened on the side of the liquid collection tank 12 away from the support platform 3 and the storage pit body 1. The push plate 10 and several adjusting rods 11 are all located in the drain port 121.

[0032] More specifically, by setting up the collection tank 12 and the drain outlet 121, the sewage discharged from the inside of the drain pipe 2 can be smoothly guided to the external sewage pool without the sewage affecting the normal operation of components such as the drive mechanism 6, the lead screw 7, and the slide bar 9.

[0033] Please refer to the following: Figures 1-4 Several adjusting rods 11 and several drain pipes 2 are arranged in parallel and distributed at equal intervals.

[0034] More specifically, by setting the adjusting rod 11 and the drain pipe 2 to be parallel and equidistant, the sewage inside the storage pit body 1 can be discharged more evenly into the external sewage pool.

[0035] Please refer to the following: Figures 1-4 Several adjusting rods 11 are evenly divided into multiple rows, and the inclination angle of the inclined surface 111 of each row of adjusting rods 11 is different.

[0036] More specifically, by setting different angles for the inclined surfaces 111 in different rows, different flow rates can be controlled for different drain pipes 2 as the adjusting rod 11 is inserted into the drain pipe 2. Because the diameter of the outer wall of the adjusting rod 11 matches the diameter of the inner wall of the drain pipe 2, the drain pipe 2 can be completely blocked when the adjusting rod 11 is inserted into it. However, when only the inclined surface 111 is inserted into the drain pipe 2, it cannot completely block the drain pipe 2, so sewage can still be discharged normally inside the drain pipe 2. Furthermore, the longer the inclined surface 111 is, the longer the distance that the push plate 10 and the adjusting rod 11 need to move. Therefore, even when some short inclined surfaces 111 have blocked part of the drain pipe 2, other inclined surfaces 111 and drain pipes 2 can still discharge sewage normally.

[0037] Please refer to the following: Figures 1-4 The inclined surface 111 of the multi-row adjusting rod 11 increases in size from top to bottom.

[0038] More specifically, since sewage tends to flow downwards, this design allows for blocking part of the upper drain pipe 2 without affecting the sewage discharge below.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
