Description

Small oil separator

Technical Field

The invention relates to the field of environment-friendly water treatment, in particular to a small oil separator for treating kitchen catering wastewater.

Background

Restaurant wastewater discharged from a kitchen contains a large amount of grease and solid residues, and is discharged into a municipal pipe network without treatment, so that the pipeline is extremely easy to block, and the restaurant wastewater also has extremely bad influence on a rear-end sewage treatment plant. Grease and solid residues in the restaurant wastewater must be separated and removed, and the restaurant wastewater can be discharged into a municipal pipe network after meeting the national discharge standard. Therefore, the oil separator becomes an essential facility for industries such as restaurants, hotels and the like.

As shown in figure 1, the conventional restaurant wastewater treatment mode is a centralized treatment mode after being collected through a pipe network, firstly, restaurant wastewater generated by kitchens in all floors in a building is collected by a branch pipe ①, then is collected into a main pipe ② and enters an oil separator facility ③ for oil separation and residue separation, and the treated standard wastewater is discharged into a municipal pipe network through a water outlet pipe ④.

The inventor of the invention finds that the following problems exist in the actual engineering application by adopting the restaurant wastewater treatment mode:

1. a large amount of special collecting pipe networks for the restaurant wastewater need to be tied up, so that not only is the construction cost increased, but also the design and construction of the building pipe networks become complicated;

2. the distance between branch pipelines and main pipelines from a kitchen wastewater source to an oil separation facility is far, and the branch pipelines and the main pipelines are arranged transversely, vertically and crosswise, so that grease and residues in the section of the pipeline are gradually deposited, and the pipeline has the hidden trouble that the pipeline is finally blocked and cannot be drained;

3. waste water of other properties in the kitchen, such as non-catering nature waste water of ground scouring, sanitary washing etc. also can enter into the collection pipe network because of dividing the bad easily, can't accomplish accurate collection. The amount of wastewater entering the oil separator equipment is greatly increased, and the treatment effect is influenced.

Disclosure of Invention

Aiming at the defects of the prior art, the technical problems to be solved by the invention are as follows: the restaurant wastewater generated in the kitchen does not need to be collected through a network and then is treated in a centralized manner, but can be effectively treated at the source point of the restaurant wastewater in the kitchen.

In order to achieve the purpose, the invention adopts the technical scheme that: a small grease trap mountable under a kitchen counter is provided.

As shown in fig. 2, in a general case where a kitchen counter basin a is a source point of generating restaurant wastewater, a small oil separator B can be easily installed in a narrow space under the counter basin a. Restaurant wastewater from the source is treated in the small oil separator B through the downpipe and then directly discharged into a rear-end sewage pipeline, which is the working mode of the small oil separator.

The small-sized oil separator comprises:

the separation box is provided with a water inlet at the top, a drawing type slag basket is arranged right below the water inlet and can be drawn out from the front panel, and the front panel is provided with an observation window; the top of the separation box is provided with a movable cover plate, and the movable cover plate is provided with a buckle to be fixed with the separation box; the bottom of the separator is provided with movable casters which are convenient to carry and move; an oil pumping pipe and a water outlet guide plate are arranged on the inner side of the end face of the separation box, and a water outlet and a wire box are arranged on the outer side of the end face of the separation box.

The vacuum oil pumping device comprises an oil discharge hose, an oil storage box, an underframe, a vacuum pump wire, a pump shell, an exhaust tube and a vacuum pump, wherein the vacuum pump is fixedly installed in the pump shell, the vacuum pump wire and the exhaust tube penetrate through the top of the pump shell, the wire is connected with the wire box, the exhaust tube is connected with the oil storage box, the oil discharge hose is connected with the oil storage box through a quick-release chuck, and the vacuum oil pumping device is integrally connected with a separation box through the underframe.

Heating device, heating device is by fixed screw fixed mounting on the outer wall of separator box, including heating wire, temperature controller, shell plate, heat preservation cotton, heating plate, the heating plate pastes the dress at the separator box outer wall, and the cotton cover of heat preservation is on the heating plate surface, and the shell plate covers the heating plate and the cotton dress of hanging by fixed screw on the separator box again of heat preservation, is equipped with heating wire and temperature controller on the heating plate.

When this equipment was handled food and beverage waste water, at first, the waste water in the kitchen counter basin flows into the separator box from the water inlet, and bold solid residue can be intercepted by pull formula sediment basket to follow separator box the place ahead panel and take out the sediment basket and clear up, reach the purpose that separates the residue with this. The oily wastewater after the residue is separated enters the box body and fully stays, in the staying process, the oil with low density can float on the liquid level to form an oil layer, and the water with high density is discharged from the water outlet from the bottom of the box body through the guide plate, so that the purpose of separating the oil is achieved. When the oil layer on the liquid level is checked through the observation window on the front panel to reach a certain thickness, the oil can be discharged and cleaned by the vacuum oil pumping device matched with the rear end through the oil pumping pipe. In order to prevent the oil layer in the box body from solidifying and being discharged due to low temperature, the outer side wall of the separation box is not provided with a heating constant temperature device, so that the oil layer in the box body can be ensured to have good fluidity.

In summary, the invention has the following advantages:

1. the source on-site treatment of the kitchen catering waste water can be realized, and a collecting pipe network does not need to be tied up for centralized treatment;

2. the pull-type slag basket is convenient to clean, the cleaning can be carried out without opening a cover plate of the box body, the vacuum oil collecting device can directly discharge the grease to the oil storage box, manual cleaning is not needed, and the daily use and maintenance of the equipment are very convenient;

3. the grease in the box body can realize constant temperature heating to prevent solidification, and is suitable for being used in low temperature environment.

The invention is described in more detail below with reference to the accompanying drawings.
