Description

Technical Field

[0001] This utility model relates to the field of garbage collection technology, and in particular to a sewage collection device for garbage collection vehicles. Background Technology

[0002] With the acceleration of urbanization, the amount of garbage generated is increasing day by day, and the importance of garbage collection and transportation is becoming more and more prominent. If the sewage in the garbage is not properly treated during the garbage collection and transportation process, it will cause a series of environmental and operational problems.

[0003] Traditional garbage collection vehicles often lack effective wastewater collection and treatment mechanisms. Wastewater from the garbage flows freely during transportation, not only polluting the vehicles themselves, causing corrosion, emitting foul odors, and shortening their lifespan, but also leaking at garbage loading and unloading sites and along the transportation route, causing serious pollution to the road environment and increasing the difficulty and cost of road cleaning. In addition, solid waste mixed in with the wastewater may accumulate in discharge pipes or treatment equipment, causing pipe blockages, equipment malfunctions, and other problems, reducing the efficiency of wastewater discharge and treatment and affecting the normal operation of the entire garbage treatment system.

[0004] Therefore, we propose a wastewater collection device for garbage collection vehicles. Utility Model Content

[0005] The main purpose of this utility model is to provide a sewage collection device for garbage collection vehicles. In order to prevent sewage from flowing randomly during garbage collection and polluting the vehicle and road environment, and to prevent solid waste in the sewage from clogging the discharge pipes and treatment equipment, the device aims to improve the overall efficiency and environmental friendliness of garbage collection and subsequent treatment, and ensure the stable operation of the garbage treatment system. It can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A wastewater collection device for a garbage collection vehicle includes a collection box, a wastewater tank on the inner wall of the bottom end of the collection box, a chute inside the wastewater tank, a collection box slidably connected to the chute, a handle welded to the outer wall of one end of the collection box, a first filter screen at the bottom of the collection box, symmetrical mounting grooves on both sides of the bottom end of the collection box, multiple equidistant connecting shafts fixedly connected to each of the two mounting grooves, rollers rotatably connected to the outside of the multiple connecting shafts via bearings, two symmetrical limiting strips at the bottom end of the chute, the limiting strips being directly below the mounting grooves, the rollers slidably connected to the limiting strips, and limiting grooves matching the limiting strips being provided on the rollers;

[0008] The sewage tank has multiple evenly distributed threaded grooves inside and below the chute. A crusher housing is threadedly connected inside the threaded grooves. A crushing motor is installed in the middle of the crusher housing. Fixing rods are fixedly connected to the outer walls on both sides of the crushing motor. The end of the fixing rod away from the crushing motor is fixedly connected to the inner wall of the crusher housing. A crushing blade is fixedly connected to the output end of the crushing motor.

[0009] By adopting the above technical solution, after the garbage is loaded into the collection container, the sewage will flow through the garbage layer into the sewage tank. When the sewage passes through the first filter screen at the bottom of the collection box, larger particles of impurities are intercepted by the first filter screen and trapped in the collection box. As the sewage collection volume increases, when it is necessary to clean the collection box, by pulling the handle, the collection box is moved horizontally out of the sewage tank by the sliding of the rollers on the connecting shaft in the mounting groove on the limit strip, which facilitates the cleaning of impurities in the collection box. The sewage flowing into the sewage tank and passing through the first filter screen continues to flow downward and enters the crusher housing. When the crushing motor is started, the crushing motor drives the crushing blades to rotate at high speed, crushing some larger solid garbage remaining in the sewage into smaller particles or fragments, so as to facilitate subsequent sewage discharge and treatment, prevent these solid garbage from clogging the sewage discharge pipes or sewage treatment equipment, and make the sewage discharge and subsequent treatment process smoother.

[0010] Furthermore, the sewage tank is provided with a water storage chamber inside, and the water storage chamber is located below the slide groove. A connecting pipe is provided between the water storage chamber and the threaded groove, and a check valve is provided inside the connecting pipe.

[0011] By adopting the above technical solution, when sewage flows into the sewage tank, the sewage that has been initially filtered by the collection box and the first filter screen will continue to flow downward under the action of gravity. Since the water storage chamber and the threaded groove are connected by a connecting pipe and a check valve is installed in the connecting pipe, sewage can flow from the area where the crusher shell is located into the water storage chamber for storage through the connecting pipe. The function of the check valve is to prevent the sewage in the water storage chamber from flowing back into the crusher shell or the area above it, ensuring that the sewage flows and is stored in the sewage tank in a predetermined direction, avoiding equipment failure or sewage backflow that may cause contamination of the treated area.

[0012] Furthermore, a filter frame is fixedly installed on the top of the sewage tank, and a second filter screen is provided inside the filter frame.

[0013] By adopting the above technical solution, when garbage is inside the collection container, the wastewater it contains first passes through the second filter screen located in the filter frame at the top of the wastewater tank as it flows into the wastewater tank. The second filter screen performs preliminary filtration of the wastewater, intercepting some larger impurities and floating objects, such as large pieces of plastic, leaves, and paper. After this layer of filtration, the relatively clean wastewater continues to flow downwards into other areas of the wastewater tank, such as passing through the collection box below and the first filter screen at the bottom for further filtration, or flowing into the water storage chamber, etc., thereby gradually achieving stratified filtration and removal of impurities in the wastewater. This makes the finally collected wastewater easier for subsequent treatment and discharge, while also reducing the risk of clogging or damage to the crusher or other components inside the wastewater tank.

[0014] Furthermore, a drain outlet is fixedly connected to the lower part of one end of the sewage tank near the handle and located in the water storage chamber, and a solenoid valve is installed on the drain outlet.

[0015] By adopting the above technical solution, when it is necessary to discharge the sewage that has undergone multiple filtrations and treatments from the sewage tank, the sewage discharge operation is achieved by controlling the solenoid valve installed on the drain outlet. During the sewage collection stage, the solenoid valve is in the closed state to ensure that the sewage can complete a series of processes in the sewage tank, such as preliminary filtration at the collection box, solid waste crushing at the crusher shell, and storage in the water storage chamber, preventing the sewage from flowing out prematurely. When the vehicle arrives at the designated sewage discharge point, or when the sewage in the sewage tank reaches the conditions for discharge, such as when the storage volume is close to the upper limit, the corresponding control device, such as the control system inside the vehicle, sends an opening signal to the solenoid valve. At this time, the solenoid valve opens, and the sewage in the water storage chamber is smoothly discharged from the sewage tank through the drain outlet under the action of gravity, so that the sewage can be transported to subsequent sewage treatment facilities for further treatment, thereby completing the entire cycle of sewage collection and discharge for garbage collection vehicles.

[0016] Furthermore, a door is rotatably connected to one end of the waste collection container, and a lid is rotatably connected to the lower part of the side of the door away from the waste collection container. Sealing rings are installed on the four sides of the inner wall of the lid.

[0017] By adopting the above technical solution, the door at one end of the collection container serves to seal the container, facilitating the loading and unloading of waste. When waste needs to be emptied from the container, the door can be opened; after unloading, the door is closed to prevent waste from falling out during transport. The cover, which rotates and connects to the lower part of the side of the container away from the door, allows operation of the wastewater tank without opening the door. The sealing rings installed on the four sides of the inner wall of the cover are primarily for preventing potential leakage of wastewater from the waste. During waste transport, wastewater may seep from the gap between the door and the cover; the sealing rings effectively fill this gap, creating a good seal. When the cover is closed, the sealing rings are compressed and tightly adhere to the contact surfaces of the door and cover, preventing wastewater from leaking out of the vehicle and avoiding environmental pollution. This also helps maintain the cleanliness of the vehicle's exterior and contributes to the overall hygiene of the waste collection vehicle, reducing odor emissions.

[0018] Furthermore, the top of the waste collection container is provided with a dispensing port.

[0019] By adopting the above technical solution, during garbage collection operations, staff can conveniently put various types of garbage into the collection container through this disposal port.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] (1) The present invention provides a sewage collection device for garbage collection vehicles. By setting a collection box with a first filter screen inside the sewage tank, it can effectively intercept larger particulate impurities in the sewage and prevent them from entering the subsequent treatment process. The collection box adopts a sliding connection method of rollers and limit strips, which makes it easy to remove and clean from the sewage tank. It is convenient to operate and can significantly improve the efficiency of impurity treatment in the sewage collection process, reduce the difficulty and time cost of manual cleaning, and ensure the continuous and stable operation of the sewage collection device.

[0022] (2) The wastewater collection device for garbage collection vehicles of this utility model has a crusher shell and a crushing motor and crushing blade located below the wastewater tank. It can crush the large-volume solid waste remaining in the wastewater that has passed through the first filter screen. After crushing the solid waste into smaller particles or fragments, it can effectively prevent it from causing blockage in the wastewater discharge pipe or wastewater treatment equipment, ensure smooth wastewater discharge, improve the reliability and stability of the entire wastewater discharge and treatment system, facilitate the efficient operation of subsequent wastewater treatment processes, and reduce equipment maintenance costs and failure rate.

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] To prevent wastewater from flowing indiscriminately during garbage collection and polluting vehicles and roads, and to prevent solid waste in wastewater from clogging discharge pipes and treatment equipment, thereby improving the overall efficiency and environmental friendliness of garbage collection and subsequent treatment, and ensuring the stable operation of the garbage treatment system, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, a wastewater collection device for a garbage collection vehicle includes a collection box 1. A wastewater tank 4 is provided on the inner wall of the bottom end of the collection box 1. A sliding groove 5 is provided inside the wastewater tank 4. A collection box 6 is horizontally slidably connected in the sliding groove 5. A handle 23 is welded to the outer wall of one end of the collection box 6. A first filter screen 12 is provided at the bottom of the collection box 6. Symmetrical mounting grooves 7 are provided on both sides of the bottom end of the collection box 6. Multiple connecting shafts 8 are fixedly connected in both mounting grooves 7 at equal intervals. Rollers 9 are rotatably connected to the outside of the multiple connecting shafts 8 through bearings. Two symmetrical limiting strips 10 are provided at the bottom end of the sliding groove 5. The limiting strips 10 are located directly below the mounting grooves 7. The rollers 9 are slidably connected to the limiting strips 10. The rollers 9 are provided with limiting grooves 11 that match the limiting strips 10.

[0031] The sewage tank 4 has multiple evenly distributed threaded grooves 13 inside and below the chute 5. The crusher housing 14 is threadedly connected inside the threaded grooves 13. The crusher motor 15 is installed in the middle of the crusher housing 14. Fixing rods 16 are fixedly connected to the outer walls on both sides of the crusher motor 15. The end of the fixing rod 16 away from the crusher motor 15 is fixedly connected to the inner wall of the crusher housing 14. The crushing blade 17 is fixedly connected to the output end of the crusher motor 15.

[0032] During use, after the garbage is loaded into the collection box 1, the sewage flows through the garbage layer into the sewage tank 4. When the sewage passes through the first filter screen 12 at the bottom of the collection box 6, larger particles of impurities are intercepted by the first filter screen 12 and trapped inside the collection box 6. As the sewage collection volume increases, when it is necessary to clean the collection box 6, by pulling the handle 23, the collection box 6 is moved horizontally out of the sewage tank 4 by the sliding of the roller 9 on the connecting shaft 8 in the mounting groove 7 on the limiting strip 10, which facilitates the cleaning of impurities inside the collection box 6. The sewage that flows into the sewage tank 4 and passes through the first filter screen 12 continues to flow downward and enters the crusher housing 14. When the crushing motor 15 is started, the crushing motor 15 drives the crushing blade 17 to rotate at high speed, crushing some larger solid garbage remaining in the sewage into smaller particles or fragments, so as to facilitate subsequent sewage discharge and treatment, prevent these solid garbage from clogging the sewage discharge pipes or sewage treatment equipment, and make the sewage discharge and subsequent treatment process smoother.

[0033] For example, such as Figure 3 As shown, the present invention also includes a water storage chamber 22 inside the sewage tank 4, and the water storage chamber 22 is located below the slide groove 5. A connecting pipe 18 is provided between the water storage chamber 22 and the threaded groove 13, and a check valve 19 is provided inside the connecting pipe 18.

[0034] During use, when sewage flows into sewage tank 4, the sewage that has been initially filtered by collection box 6 and first filter screen 12 will continue to flow downward under the action of gravity. Since the water storage chamber 22 and the threaded groove 13 are connected by connecting pipe 18, and a check valve 19 is provided in the connecting pipe 18, sewage can flow from the area where the crusher housing 14 is located into the water storage chamber 22 for storage through the connecting pipe 18. The function of the check valve 19 is to prevent the sewage in the water storage chamber 22 from flowing back into the crusher housing 14 or the area above it, ensuring that the sewage flows and is stored in the sewage tank 4 in a predetermined direction, avoiding equipment failure or sewage backflow that may cause contamination of the treated area.

[0035] For example, such as Figure 2 , Figure 3 As shown, the present invention also includes a filter frame 20 fixedly installed on the top of the sewage tank 4, and a second filter screen 21 is provided on the inner side of the filter frame 20.

[0036] During use, when garbage is inside the collection container 1, the wastewater it contains flows into the wastewater tank 4. First, it passes through the second filter screen 21 within the filter frame 20 at the top of the wastewater tank 4. The second filter screen 21 performs preliminary filtration, intercepting larger impurities and floating objects such as large pieces of plastic, leaves, and paper. After this filtration, the relatively clean wastewater continues to flow downwards into other areas of the wastewater tank 4, such as passing through the collection box 6 below and the first filter screen 12 at the bottom for further filtration, or flowing into the water storage chamber 22. This process gradually achieves layered filtration and removal of impurities in the wastewater, making the collected wastewater easier to process and discharge later, while also reducing the risk of clogging or damage to the crusher or other components inside the wastewater tank 4.

[0037] For example, such as Figure 1 , Figure 2 As shown, the present invention also includes a drain outlet 24 fixedly connected to the lower part of one end of the sewage tank 4 near the handle 23 and located in the water storage chamber 22, and a solenoid valve is provided on the drain outlet 24.

[0038] When in use, when it is necessary to discharge the sewage that has undergone multiple filtrations and treatments in the sewage tank 4, the sewage discharge operation is achieved by controlling the solenoid valve installed on the drain outlet 24. During the sewage collection stage, the solenoid valve is in the closed state to ensure that the sewage can complete a series of processes in the sewage tank 4, such as preliminary filtration at the collection box 6, solid waste crushing at the crusher housing 14, and storage in the water storage chamber 22, to prevent the sewage from flowing out prematurely. When the vehicle arrives at the designated sewage discharge location, or when the sewage in the sewage tank 4 reaches the conditions for discharge, such as when the storage volume is close to the upper limit, the corresponding control device, such as the control system in the vehicle, sends an opening signal to the solenoid valve. At this time, the solenoid valve opens, and the sewage in the water storage chamber 22 is smoothly discharged from the sewage tank 4 through the drain outlet 24 under the action of gravity, so that the sewage can be transported to subsequent sewage treatment facilities for further treatment, thereby completing the entire cycle of sewage collection and discharge for garbage collection vehicles.

[0039] For example, such as Figure 1 As shown, the present invention also includes a door 2 rotatably connected to one end of the waste collection box 1, a cover 3 rotatably connected to the lower part of the side of the door 2 away from the waste collection box 1, and a sealing ring 26 installed on the four sides of the inner wall of the cover 3.

[0040] During use, the door 2 at one end of the collection container 1 serves to seal the collection container 1, facilitating the loading and unloading of garbage. When it is necessary to empty garbage from the collection container 1, the door 2 can be opened; after unloading the garbage, the door 2 should be closed to prevent garbage from falling out during transportation. The cover 3, which is rotatably connected to the lower part of the side away from the collection container 1, allows operation of the sewage tank 4 without opening the door 2. The sealing rings 26 installed on the four sides of the inner wall of the cover 3 are mainly for protection against possible leakage of sewage from the garbage. During garbage transportation, sewage in the garbage may seep out from the gap between the door 2 and the cover 3, and the sealing rings 26 can effectively fill the gap between the cover 3 and the door 2, forming a good sealing effect. When the lid 3 is closed, the sealing ring 26 is compressed and fits tightly against the contact surface of the door 2 and the lid 3, thereby preventing sewage from seeping out of the vehicle through the gap, avoiding environmental pollution, while also keeping the vehicle's appearance clean and helping to maintain the overall hygiene of the garbage collection vehicle, reducing problems such as odor emission.

[0041] For example, such as Figure 1 As shown, the present invention also includes a loading port 25 at the top of the cleaning box 1.

[0042] When in use, during garbage collection operations, staff can conveniently put various types of garbage into the collection container 1 through this disposal port 25.

[0043] It should be noted that this utility model is a sewage collection device for garbage collection vehicles. Workers deposit various types of garbage into the collection container 1 through the inlet 25 at the top. At this time, the sewage in the garbage begins to flow towards the sewage tank 4 at the bottom. The sewage first passes through the second filter screen 21 in the filter frame 20 at the top of the sewage tank 4, where larger impurities and floating objects such as large pieces of plastic, leaves, and paper are intercepted. The preliminarily filtered sewage continues to flow downwards into other areas of the sewage tank 4. Upon reaching the collection box 6 inside the sewage tank 4, the sewage passes through the first filter screen 12 at the bottom of the collection box 6, where larger particles are intercepted. As the sewage collection volume increases, the amount of impurities in the collection box 6 gradually increases. When the collection box 6 needs to be cleaned, the worker pulls the handle 23, and the collection box 6 slides horizontally out of the sewage tank 4 using the rollers 9 on the connecting shaft 8 in the mounting groove 7, moving on the limiting strip 10. Then, the impurities in the collection box 6 are cleaned.

[0044] Wastewater passing through the first filter screen 12 continues to flow downwards into the crusher housing 14. When the crushing motor 15 is started, it drives the crushing blades 17 to rotate at high speed, crushing larger solid waste remaining in the wastewater into smaller particles or fragments. The wastewater after crushing flows into the storage chamber 22 through the connecting pipe 18 for storage. The check valve 19 in the connecting pipe 18 prevents backflow of wastewater in the storage chamber 22. When the vehicle arrives at the designated wastewater discharge point or the wastewater in the wastewater tank 4 reaches the discharge conditions, such as when the storage volume is close to the upper limit, an opening signal is sent to the solenoid valve on the drain outlet 24 of the vehicle control system. The solenoid valve opens, and the wastewater in the storage chamber 22 is discharged from the wastewater tank 4 through the drain outlet 24 under gravity and transported to subsequent wastewater treatment facilities for further treatment.

[0045] Throughout the process, the door 2 of the waste collection container 1 can be opened or closed during waste loading and unloading. The door 2, the lid 3, and the sealing ring 26 prevent sewage leakage during transportation.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
