Description

Technical Field

[0001] The utility model relates to the technical field of water quality environmental protection in a branch rain drainage ditch, in particular to a self-capturing device for oil spots on the water surface in a rain drainage ditch. Background Art

[0002] In the field of chemical production, production equipment departments often have poor management of equipment grease, resulting in leakage, bubbling, dripping and leaking. Since the production equipment departments do not thoroughly deal with the dripping grease, a small amount of grease flows along the road surface in the device into the branch drain of the device, and gathers in front of the branch drain gate valve or flows into the main drain along the branch drain. When a small amount of oil is found floating on the water surface in the branch drain, the current treatment method is to put a large piece of oil absorbent felt in the water, press and push the oil absorbent felt on the water surface with a wooden stick, and then find a hook to fish out the oil absorbent felt. However, the current treatment method has the following problems: first, the volume of the oil-absorbing felt is limited, so the oil absorption treatment of the sewage is not thorough. At the same time, manual operation of the oil-absorbing felt is time-consuming and labor-intensive, and it is impossible to quickly and effectively treat the oil droplets on the surface of the branch rainwater drainage. Second, when this method is used to absorb oil from the water surface of the main rainwater drainage, due to the large water flow of the main rainwater drainage, it is also impossible to effectively treat the grease and oil droplets floating on the water surface. Third, the oil-absorbing felt can only adsorb and filter the grease on the water surface, but has poor treatment effect on other debris, which makes sewage treatment more difficult and increases treatment costs.

[0033] A box body 1, a filtering mechanism and a water guide platform 3, a water inlet 51 is provided at the upper part of a side panel of the box body 1; the filtering mechanism comprises at least two filtering layers arranged in sequence from top to bottom in the box body 1, and filter materials are evenly laid in each filtering layer to filter debris and grease in sewage; the water guide platform 3 is a prism, which is arranged at the bottom of the box body 1 and protrudes upward from the bottom so that the sewage entering the box body 1 from the water inlet 51 is guided to the water outlet 52, and the upper edge height of the water outlet 52 is lower than the height of the water guide platform 3; a water outlet 52 is provided at the lower part of at least one side panel 12 of the box body 1, and the water outlet 52 is a rectangular opening, and the upper edge height of the water outlet 52 is lower than the height of the water guide platform 3; when the box body 1 is fixedly installed in the rain drainage ditch through the support plate 15, the lower edge of the water inlet 51 is higher than the filtering mechanism, and the water surface in the rain drainage ditch is higher than the lower edge of the water inlet 51. The sewage in the rainwater drainage ditch flows into the box body 1 through the water inlet 51, flows through each filter layer from top to bottom, and finally flows out of the box body 1 through the water outlet 52. Therefore, the self-capturing device for oil droplets on the water surface of the rainwater drainage ditch of the utility model can solve the problem of self-capturing oil droplets on the drainage surface of the branch rainwater drainage ditch, and there is no need to manually operate the oil absorption felt, which is convenient to operate and efficient in treatment.

The filter mechanism includes three filter layers, which are respectively arranged in sequence from top to bottom in the box body 1 in the first filter layer 21, the second filter layer 22 and the third filter layer 23. The filter material of the first filter layer 21 is quartz particles, and the filter materials of the second filter layer 22 and the third filter layer 23 are both fiber-made oil-absorbing felt balls. The particle size of the quartz particles is ≥50 mesh, and the particle size of the oil-absorbing felt balls is 30 mm. The first filter layer 21 filters the floating debris in the drainage ditch, and the sewage containing oil spots flows through the second filter layer 22, and the oil-absorbing felt balls clean up a part of the oil spots; the sewage containing oil spots flows through the third filter layer 23, and the oil-absorbing felt balls clean up the other part of the oil spots; the smaller the ball diameter of the oil-absorbing felt balls, the better the oil absorption and cleaning effect, and the density of the gaps between the oil-absorbing felt balls determines the amount of oil spots filtered.

[0035] In one embodiment of the utility model, the water guide platform 3 is located at the bottom of the box body 1 corresponding to the third filter layer 23, and the water guide platform 3 is a quadrangular pyramid, and the four sides of the quadrangular pyramid correspond to the four sides of the box body 1. The side panels of the box body 1 are respectively the first side panel 11, the second side panel 12, the third side panel 13 and the fourth side panel 14, the first side panel 11 and the second side panel 12 are arranged oppositely, the third side panel 13 and the fourth side panel 14 are arranged oppositely, and the upper part of the first side panel 11 is provided with a water inlet 51; the water inlet 51 is opened at the upper part of the first side panel 11. The water inlet 51 is a rectangular opening, and the upper and lower edges of the water inlet 51 are parallel to the width direction of the first side panel 11 of the box body 1, and the lengths of the upper and lower edges of the water inlet 51 are equal to the width of the first side panel 11 of the box body 1. Support plates 15 are respectively provided at the four right angles of the first side plate 11 . Each support plate 15 is fixed in the rain drainage ditch by bolts so that the water inlet 51 faces the direction of water flow in the rain drainage ditch.

[0036] See Figure 2 and Figure 3 In one embodiment of the utility model, when the box body 1 is arranged in the rain drainage ditch of the main rain drainage 42 at the intersection of the branch rain drainage 41 and the main rain drainage 42, the third side panel 13 and the fourth side panel 14 of the box body 1 are respectively provided with water outlets 52, and the side surfaces of the four-sided pyramid corresponding to the water outlets 52 are all inclined surfaces.

[0037] See Figure 4 and Figure 5 In one embodiment of the utility model, when the box body 1 is arranged in the rain drainage ditch of the branch rain drainage 41 in front of the branch gate valve 6, a water outlet 52 is opened on the second side plate 12 of the box body 1 corresponding to the water guide platform 3, and the side surface of the quadrangular platform corresponding to the water outlet 52 is an inclined surface.

[0038] In summary, the utility model of a self-capturing device for oil droplets on the water surface in a rain drainage ditch at least solves the following problems in the background technology:

[0039] (1) The volume of the oil-absorbing felt is limited, so the oil absorption treatment of the sewage is not thorough. At the same time, manual operation of the oil-absorbing felt is time-consuming and labor-intensive, and it is impossible to quickly and effectively treat the oil spots on the drainage surface of the branch rainwater drainage. The first filter layer 21, the second filter layer 22 and the third filter layer 23 of the utility model, the filter material of the first filter layer 21 is quartz stone particles, and the filter materials of the second filter layer 22 and the third filter layer 23 are both fiber-made oil-absorbing felt balls. The oil-absorbing felt balls absorb and clean the oil spots on the water surface, and the sewage must flow through the above-mentioned filter layers in sequence, so there is no need for manual operation, and the treatment is fast and effective.

[0040] (2) When the oil absorption felt is manually operated to absorb oil from the water surface of the main rain drain, the grease and oil droplets floating on the water surface cannot be effectively treated due to the large water flow of the main rain drain. The self-capturing device for oil droplets on the water surface in the rain drain ditch of the utility model can be set at a selected location, such as in the rain drain ditch of the main rain drain 42 at the intersection of the branch rain drain 41 and the main rain drain 42, or in the rain drain ditch of the branch rain drain 41 in front of the branch gate valve 6, and multiple devices can also be set, so that the grease and oil droplets on the sewage water surface in the rain drain ditch can be treated thoroughly and cleanly.

[0041] (3) Oil-absorbing felt can only absorb and filter grease on the water surface, but has poor effect on other debris, making sewage treatment more difficult and expensive. The filter material of the first filter layer 21 of the self-capturing device for oil droplets on the water surface in the rain drainage ditch of the utility model is quartz stone particles, which can filter the floating debris in the rain drainage ditch.

[0042] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
