Description

Kitchen swill treatment method and treatment device

technical field

The invention relates to a method and device for treating kitchen swill.

Background technique

At present, due to the needs of operation, restaurants and restaurants will produce a large amount of food waste, especially the output of kitchen swill is astonishing. The current treatment method for kitchen swill is that the corresponding management department collects sewage charges from the operator, and then discharges it directly into the urban sewer . As we all know, the composition of swill is relatively complex, including oil, water and organic matter, but the main components are oil and water, which are easy to breed bacteria in the natural environment. If it is discharged directly without treatment, it will have a great impact on the environment, and more importantly Yes, it is directly discharged into urban drainage pipes, collected and refined by unscrupulous traders into "gutter oil", and returned to the people's dining table, which is extremely harmful to people's health. The country is currently strengthening the management of kitchen waste and promoting the installation of facilities such as oil-water isolation tanks and oil-water separators. However, the current oil-water separation method is inefficient, and the storage of swill is large, which is easy to breed bacteria and damage the environment. Therefore, a technology is needed to deal with restaurants. kitchen waste generated in restaurants, canteens, restaurants and other places, especially the treatment of kitchen swill, in order to protect the environment and recover the "gutter oil" in the swill in advance, control the source and quantity of "gutter oil", and truly ensure that it is used for Reasonable uses such as biodiesel or aviation fuel prevent criminals from letting "waste oil" flow into restaurants again.

Detailed ways

As shown in Figure 1, the kitchen swill treatment device consists of a solid-liquid separation device, an oil-water separation device, an ultra-fine solid precipitation device, a virus-killing treatment device and an oil-repelling filter treatment device.

According to shown in Fig. 2, the solid-liquid separation device corresponds to the method step A provided by the present invention, a feed port 1 is set at the solid-liquid separation device, and a coarse filter mesh 3 is installed at the feed port 1, below the feed port 1 Connected with the feed pipe 2, the lower port of the feed pipe 2 is connected with the main body of the equipment, and there is a layer of fine-pore filter mesh 4 inside the main body, and the kitchen swill is separated through the solid-liquid separation chamber 5 of the solid-liquid separation device The solid part of the swill and the liquid part of the swill are collected and stored on the fine-pore filter mesh 4 of the solid-liquid separation chamber 5, and the solid part of the swill is regularly cleaned out from the side of the main body of the equipment and treated as domestic solid waste.

The ultra-fine solid precipitation device and the oil-water separation device correspond to step B of the method provided by the present invention. The separated swill liquid part enters the equipment main body and is first stored in the container 6. Before the swill liquid part enters the oil-water separation system, it will still There are finer solids mixed in the liquid part of the swill, which will form ultra-fine solid sediment 22 and settle at the bottom of the container 6. The ultra-fine solid sediment 22 passes through the ultra-fine solid sediment outlet 23 of the equipment. When the equipment is regularly drained of liquid After cleaning, the ultrafine solid sediment 22 is an organic substance, which can be sterilized, dried or directly used as agricultural fertilizer.

The liquid part of the swill after superfine solid precipitation enters the oil-water separation device. The oil-water separation device consists of a drive driving wheel 12, a lower driven wheel 13, an upper driven wheel 14, an oil-absorbing conveyor belt 15, a driving extrusion wheel 16, and an auxiliary extrusion wheel. The pressure roller 17 and the oil collecting tank cavity 11 are composed. The driving driving wheel 12, the lower driven wheel 13, the upper driven wheel 14, and the oil-absorbing transmission belt 15 form a grease carrying system; the active extrusion wheel 16 and the auxiliary extrusion wheel 17 form a grease separation system. During the rotation of the grease carrying system, the oil-absorbing transmission belt 15 will absorb the grease in the liquid part of the swill into the honeycomb cavity 28, carry it out of the water surface, meet the grease separation system, be squeezed and separated into oil droplets, and fall into the oil tank cavity 11, and store in the separated oil in the oil tank cavity 11 Lead out the equipment through the pipe.

The antivirus treatment device and the oil-repelling filtration treatment device correspond to step C of the method provided by the present invention. The oil-resistance filtration treatment device is composed of a hydrophobic base filter membrane 24 , a drain valve 26 and a drain pipe 25 . After the oil-water separation, the water body is discharged after being treated by the oil-repelling filter treatment device. Since the swill separation water still has a small amount of oil dissolved in the water, when passing through the oil-resistance filter treatment device, the hydrophobicity in the oil-resistance filter treatment device The base filter membrane 24 will prevent the dissolved oil in the water from being discharged, so that the concentration of the dissolved oil in the water will increase due to filtration. When the dissolved oil exceeds the limit, it will be precipitated and floated to be processed again by the oil-water separation device. The swill after treatment through the oil-repelling filter treatment device, the oil carried, etc. have reached the sewage standard that can be discharged directly.

A virus-killing treatment device 29 is installed on the top of the equipment body, and the virus-killing treatment device is made of an ultraviolet lamp or an ozone generator. It can continuously sterilize and disinfect the oil-water separation device, ultra-fine solid precipitation device and oil-repelling filtration treatment device in real time, and sterilize and disinfect the water body to prevent the growth of bacteria inside the equipment and cause the swill water to deteriorate and stink.

As shown in FIG. 3 , the front of the entire oil-absorbing conveyor belt 15 is processed into a honeycomb shape by rubber material, and the honeycomb cavity walls 27 form hexagonal concave honeycomb cavities 28 one by one.

As shown in FIG. 4 , the oil-absorbing transmission belt 15 is composed of two layers, one is a transmission belt 30 processed from wear-resistant materials, and the other is a concave honeycomb cavity 28 layers. The concave honeycomb cavity 28 is composed of the honeycomb cavity side wall 33, the honeycomb cavity bottom wall 32, and the honeycomb cavity cornice 31. The concave honeycomb cavity 28 forms a honeycomb cavity ridge line 35 because the concave honeycomb cavity 28 is hexagonal, and the honeycomb cavity bottom wall 32 is a circle. The arc shape can make it difficult for the grease to form a dead corner of the memory.

The present invention is not limited to the above-mentioned best implementation mode, anyone can draw other various forms of products under the inspiration of the present invention, but no matter make any changes in its shape or structure, all those with the same or similar features as the present application Approximate technical solutions all fall within the protection scope of the present invention.
