Description

Technical Field

[0001] This utility model relates to the field of workshop drainage technology, and in particular to a workshop sewage drainage device with filtration function. Background Technology

[0002] In some production workshops in the food, chemical, and biopharmaceutical industries, tap water is sometimes used to wash the floor in order to keep the workshop floor clean. The wastewater and dirt after washing are then discharged through floor drains or drainage channels.

[0003] Existing drainage devices, such as the drainage filter for a seafood processing workshop disclosed in patent CN218653217U, include a filter box, a drain pipe, a guide cover, a grating plate, and a filter screen. Wastewater enters the filter box through the grating plate, and after being filtered by the filter screen, it is discharged through the drain pipe. Although it can play a certain role in drainage filtration, this drainage filter still has the following drawbacks:

[0004] 1. The filter screen of this drainage filter is attached to the receiving frame. When there are a lot of impurities or garbage in the sewage, the filter screen will be buried. The cleaning head alone cannot achieve the cleaning effect. The filter screen needs to be removed for cleaning. However, the filter screen is buried at the bottom and has a flat structure, so it is not convenient to remove the filter screen, which makes it inconvenient to clean impurities or garbage.

[0005] Second, the drainage filter has a direct discharge structure, and the space above the grating plate is directly connected to the drainage pipe. The drainage pipe is usually connected to the sewer or sewage tank. Odors from the sewer or sewage tank will return to the workshop through the drainage pipe, causing air pollution in the workshop. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model discloses a workshop wastewater drainage device with filtration function, including a tank, a cover plate, an upper filter tank, and a lower filter tank. The cover plate is detachably installed at the opening at the top of the tank. The lower filter tank is installed at the bottom inside the tank. The upper filter tank is installed inside the tank and above the lower filter tank. A water storage chamber is provided on one side of the tank located between the upper and lower filter tanks. A through hole communicating with the lower filter tank is provided on the inner side of the water storage chamber. A drain outlet is provided on the outer side of the water storage chamber. The height of the drain outlet in the vertical direction is higher than the height of the through hole. Multiple drainage holes are provided on the cover plate. A number of first filter holes are provided on the outer wall of the upper filter tank, and a number of second filter holes are provided on the outer wall of the lower filter tank.

[0007] Furthermore, the upper filter tank is provided with an outwardly inclined support plate along its upper edge, and the inner wall of the tank is provided with an outwardly inclined support slope at a position corresponding to the support plate.

[0008] Furthermore, the top opening of the trough is provided with a stepped portion, and the cover plate is arranged around the stepped portion.

[0009] Furthermore, a connecting port is provided on each side of the outer wall of the upper side of the tank, and a guide groove is provided on the outside of the connecting port.

[0010] Furthermore, the bottom of the lower filter tank is provided with multiple support legs, which support the lower filter tank on the bottom of the tank body.

[0011] Furthermore, the diameter of the first filter hole is larger than the diameter of the second filter hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention, through the setting of an upper filter tank and a lower filter tank, can perform graded filtration of impurities or garbage in sewage. Larger impurities or garbage are trapped in the upper filter tank, while smaller impurities or garbage are trapped in the lower filter tank. The upper and lower filter tanks are easy to remove and clean at any time. Furthermore, the setting of a water storage chamber isolates the drain outlet from the inside of the tank, preventing odors from entering the workshop from the drain outlet, thereby achieving the effect of odor isolation and helping to maintain fresh air in the workshop.

[0024] like Figure 1-3 As shown, the workshop sewage drainage device with filtration function in this embodiment includes a tank 1, a cover plate 2, an upper filter tank 3 and a lower filter tank 4. The cover plate 2 is detachably installed at the opening at the top of the tank 1. Specifically, the opening at the top of the tank 1 is provided with a step 11. The cover plate 2 is attached to the step 11 around its perimeter. When the cover plate 2 is placed at the opening of the tank 1, its top surface is flush with the ground and will not affect the normal passage of personnel or vehicles.

[0025] The cover plate 2 is provided with multiple drainage holes 21, which facilitates the flow of water from the workshop floor into the tank 1 through the drainage holes 21.

[0026] The lower filter tank 4 is located at the bottom of the inner side of the tank body 1, and the upper filter tank 3 is located inside the tank body 1 and above the lower filter tank 4. The outer wall of the upper filter tank 3 is provided with a number of first filter holes 31, and the outer wall of the lower filter tank 4 is provided with a number of second filter holes 41. The diameter of the first filter holes 31 is larger than the diameter of the second filter holes 41. In this way, larger impurities or garbage are trapped in the upper filter tank 3, while smaller impurities or garbage are trapped in the lower filter tank 4, thereby realizing the graded collection and treatment of waste.

[0027] The upper filter tank 3 is provided with an outwardly inclined support plate 32 along its upper edge. The inner wall of the tank body 1 is provided with an outwardly inclined support slope 12 at a position corresponding to the support plate 32. Through the cooperation of the support plate 32 and the support slope 12, the upper filter tank 3 is set inside the tank body 1.

[0029] The tank 1 has a water storage chamber 5 on one side of the upper filter tank 3 and the lower filter tank 4. The inner side of the water storage chamber 5 has a through hole 51 that communicates with the lower filter tank 4. The outer side of the water storage chamber 5 has a drain outlet 52. The height of the drain outlet 52 in the vertical direction is higher than the height of the through hole 51. Specifically, the height of the lowest point of the drain outlet 52 is not lower than the height of the highest point of the through hole 51. The purpose of this design is that when there is sewage remaining in the water storage chamber 5, its highest water level can just seal the through hole 51, so that the odor from the sewer or sewage tank cannot enter the workshop from the drain outlet 52, thereby achieving the effect of isolating odors and helping to keep the workshop air fresh.

[0030] A connecting port 13 is provided on each side of the outer wall on the upper side of the tank body 1. A guide channel 6 is provided on the outside of the connecting port 13. The cross-sectional shape of the guide channel 6 can be U-shaped, rhomboid, square, arc-shaped, etc. Through the guide channel 6, sewage from other parts of the workshop can be guided into the tank body 1, thereby achieving filtration and discharge.
