Description

Technical Field

[0001] The utility model relates to a compression type leachate discharge device for a garbage truck, belonging to the field of garbage truck filters. Background Art

[0002] Compression garbage trucks are primarily used to transport household waste. Using advanced compression technology, they can compress waste to an extremely small volume, maximizing the load capacity. Household waste often contains a large amount of wet waste. Compression in compression garbage trucks reduces the volume of the waste, squeezing out the water contained in the wet waste, forming leachate, which flows out through the gaps. To prevent leachate from spilling onto the ground, compression garbage trucks are equipped with two sewage tanks. One is located at the bottom of the vehicle body and receives sewage from the front end of the tank, known as the front sewage tank; the other is located at the bottom of the filler and receives sewage from the rear of the vehicle, known as the rear sewage tank.

[0003] Landfill leachate has a complex composition, containing suspended impurities and silt. It is highly corrosive and prone to precipitation. If leachate remains in a sewage tank for an extended period without being discharged, it can cause severe corrosion and shorten the tank's service life.

[0004] In order to discharge the leachate in time, existing compression garbage trucks generally have a sewage outlet on the sewage tank to discharge the leachate in time and clean the sediment and silt accumulated at the bottom of the sewage tank.

[0005] However, when the existing sewage tank outlet is in use, the moment the driver opens the gate to waterproof, leachate can easily splash uncontrollably, easily splashing around, onto the driver's work clothes and the surrounding ground, causing secondary pollution. Furthermore, the leachate must be discharged into the municipal sewage well. The uncontrolled discharge of leachate from garbage trucks ultimately fails to meet environmental protection requirements.

[0006] Nowadays, some vehicle manufacturers install flow-controlled drain valves (mainly ball valves) on the sewage tanks of garbage trucks. Although this has helped to stabilize the discharge of leachate, the suspended impurities and silt in the leachate can easily cause the drain valve to become clogged over time, resulting in poor drainage. Utility Model Content

[0010] Furthermore: a plurality of first reinforcing ribs are evenly distributed on the circumference of the conical ring wall, a second reinforcing rib is provided on the bottom plate, and the first reinforcing ribs and the second reinforcing ribs are integrally formed.

[0011] Furthermore: the water filtering structure also includes an upper edge ring, the upper edge ring and the conical ring wall are integrally formed, and one end of the first reinforcing rib is connected to the upper edge ring.

[0012] Furthermore: the elongated filtering holes are also provided at the junction of the conical ring wall and the bottom plate.

[0013] Furthermore: the ends of the stainless steel welded pipe and the ends of the drain belt are both provided with flanges, and the upper edge ring is provided between the flanges.

[0014] Furthermore: a rubber gasket is provided between the upper edge ring and the flange.

[0015] Furthermore: the drain belt is connected to the stainless steel welded pipe through a gate valve.

[0028] See Figure 1-3 This is an embodiment of a compression type leachate discharge device for garbage trucks of the present invention.

[0029] It comprises a stainless steel welded pipe 1 and a drainage belt 2 connected to the stainless steel welded pipe 1 . A water filtering structure 3 is provided between the stainless steel welded pipe 1 and the drainage belt 2 .

[0030] Flanges 4 are installed at the ends of the stainless steel welded pipe 1 and the ends of the drain belt 2. An upper ring 37 located in the water filter structure 3 is positioned between the flanges 4. A rubber gasket 5 is also installed between the upper ring 37 and the flange 4. The drain belt 2 is connected to the stainless steel welded pipe 1 via a gate valve 6.

[0031] When installing this device, one end of the stainless steel welded pipe 1 is welded to the sewage tank of the garbage truck, and the other end is welded to the flange 4; the flange 4 is made of stainless steel, and the other end is welded to the stainless steel gate valve 6, with a rubber gasket 5 and a water filter structure 3 arranged in the middle. At the same time, a drain belt 2 is connected to the stainless steel gate valve 6 to achieve the connection of the entire device;

[0032] With this arrangement, when the gate valve 6 is opened, the water in the sewage tank can smoothly enter the stainless steel welded pipe 1, and then be filtered by the water filtering structure 3 and output from the drainage belt 2; the output end of the drainage belt 2 can be directly placed in the municipal sewage pipe well, and the leachate flows directly into the sewage pipe network through the water belt, avoiding splashing and secondary pollution.

[0033] Since the sewage in the sewage tank will carry impurities such as sludge, a water filtering structure 3 is set in this device, which is mainly used to filter the impurities in the sewage;

[0034] Specifically, in order to improve the filtering effect, the present device improves the water filtering structure 3. The water filtering structure 3 includes an integrally formed conical ring wall 31 and a bottom plate 32. The conical ring wall 31 is provided with elongated filtering holes 33, and the bottom plate 32 is provided with circular filtering holes 34. The conical ring wall 31 conforms to the direction of the water flow, which can concentrate the water flow, increase the flow rate of the water flow, and improve the filtering effect. At the same time, a plurality of elongated filtering holes 33 are arrayed on the conical ring wall 31. These elongated filtering holes 33 are arranged at an angle, which can achieve the filtration of sewage without affecting the flow rate.

[0035] At the same time, filtering only by relying on the inclined long strip filter holes 33 is not effective, so a circular filter hole 34 is set on the bottom plate 32. When the water flow hits the bottom plate 32, impurities will be filtered by the circular filter holes 34, and clean water will pass through the circular filter holes 34; at the same time, due to the setting of the bottom plate 32, the water flow will hit the bottom plate 32, and then flow out from the long strip filter holes 33 of the side conical ring wall 31; this can reduce the impact of some water flow on the bottom plate 32.

[0036] In order to improve the overall strength of the water filter structure 3 against water flow impact, a plurality of first reinforcing ribs 35 are evenly distributed on the circumference of the conical ring wall 31, and a second reinforcing rib 36 is provided on the bottom plate 32. The first reinforcing rib 35 and the second reinforcing rib 36 are integrally formed.

[0037] The first reinforcing rib 35 can enhance the impact resistance of the conical ring wall 31, and the second reinforcing rib 36 can enhance the impact resistance of the bottom plate 32. At the same time, the first reinforcing rib 35 and the second reinforcing rib 36 are integrally formed, so that the first reinforcing rib 35 and the second reinforcing rib 36 can resist water impact at the same time.

[0038] The water filtering structure 3 further includes an upper edge ring 37 , which is integrally formed with the conical ring wall 31 , and one end of the first reinforcing rib 35 is connected to the upper edge ring 37 .

[0039] The main function of the upper edge ring 37 of this device is to facilitate the installation of the water filtering structure 3.

[0040] A long strip filter hole 33 is also provided at the junction of the conical ring wall 31 and the bottom plate 32 .

[0041] In order to reduce the impact of water flow on the water filtering structure 3 in this device, the junction of the conical ring wall 31 and the bottom plate 32 is set to be an arc shape; at the same time, when water hits the junction, the long strip filter holes 33 set can allow water to pass through, further reducing the impact of the water flow.

[0042] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
