Description

Energy-saving kitchen garbage dewatering device

Technical Field

The utility model relates to a rubbish dehydration field especially relates to an energy-saving kitchen garbage dewatering device.

Background

There are two definitions of kitchen waste: one is the residue and waste from the catering industry and unit canteens; the other is the oil-containing hogwash mainly discharged by restaurant, hotel and other food industries. In any definition, the kitchen waste includes tableware and kitchen utensil cleaning water, rice water, leftover, fish bone, bone residue, melon and vegetable skin, etc., and is a mixture of residual food, water and organic substances such as starch, dietary fiber, animal fat, etc. as main components.

The kitchen waste has the following characteristics: (1) organic pollutants are the main, and the nutrient content is high; (2) contains solid materials such as animal bones, scraps, bone spurs and the like, and has high water content; (3) the contents of oil and fat (animal oil and vegetable oil) and salt are high; (4) is easy to decay and ferment and stink.

At present, the kitchen waste generated by domestic canteens, restaurants, hotels and hotels is transported to a kitchen waste treatment center, an urban domestic waste landfill disposal site and an urban domestic waste incineration plant in a centralized collection and transportation mode for harmless, stabilization and resource treatment. Before concentrated collection and transportation, effective dehydration pretreatment is not carried out, so that the moisture content in the kitchen waste is too high, and the difficulty of post-treatment is increased. Meanwhile, due to the existence of a large amount of moisture, the yield of the kitchen waste is overlarge, and the cost of transportation and post-treatment is greatly increased after the kitchen waste is collected, so that the cost for treating the kitchen waste in a dining room, a restaurant, a hotel and a hotel is invisibly increased. If the kitchen waste can be dehydrated and pretreated on site in a production place, the dehydration, volume reduction and weight reduction are realized, the difficulty of concentrated transportation of the kitchen waste is reduced, and the kitchen waste treatment cost for dining halls, restaurants, hotels and hotels is also reduced.

The kitchen waste treatment center generally adopts the dehydration mode to carry out the preliminary treatment, and current technological form has the heating evaporation formula, centrifugal dehydration formula, spiral press formula, wherein: external steam is introduced in the heating evaporation mode, and part of condensed water formed after heat exchange is mixed into oily sewage, so that the difficulty and cost of sewage treatment in the later period are increased; the centrifugal dehydration type has noise pollution; the screw press type is difficult to remove oil and is easy to cause material blockage.

Before kitchen waste is collected and transported, the kitchen waste is generally stacked in dining halls, restaurants, hotels and hotels by using garbage cans, and a large amount of space is occupied. Therefore, in order to save space in many dining halls, the phenomenon of randomly discarding kitchen waste or breeding the garbage pigs after private treatment exists, so that the pollution to land, air and objects is caused, mosquitoes and flies are easy to breed to influence the surrounding environment, and the influence on the health of residents by the garbage pigs bred after private treatment is larger. Therefore, it is necessary to pre-treat the kitchen waste in-situ to avoid the secondary pollution.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved by the utility model is to provide an energy-saving kitchen garbage dewatering device, the device utilizes vacuum generator to produce negative pressure zone, and the moisture in the material incasement that will save kitchen garbage is desorption from rubbish, can intermittent operation also can continuous operation.

In order to solve the technical problem, the utility model provides a following technical scheme: an energy-saving kitchen garbage dewatering device includes: the vacuum dewatering device comprises a material box, a material box cover, a porous plate, a nylon cloth bag, a negative pressure dewatering box, a vacuum pump, a pneumatic hose, a vacuum meter, a galvanized inner wire short pipe, a liquid level meter, a flange plate, a valve, a drain pipe and a drainage outlet of the negative pressure dewatering box, wherein the top of the material box is connected with the material box cover, the porous plate is arranged at the bottom of the material box, the nylon cloth bag is arranged inside the material box, the negative pressure dewatering box is arranged at the lower side of the porous plate, the vacuum pump is connected with the galvanized inner wire short pipe at the top end of the negative pressure dewatering box through the pneumatic hose, the vacuum meter is arranged on the pneumatic hose, the liquid level meter is arranged on one side of the negative pressure dewatering box, the drain pipe is connected with the drainage outlet of the negative pressure.

Furthermore, the negative pressure dewatering box is connected with one or more material boxes through a pneumatic hose. When only one material box is arranged, the device is in an intermittent operation mode; when two or more than two material tanks are arranged, the device can realize a continuous operation mode.

Further, the vacuum pump is any one of a diaphragm vacuum pump, a water circulation vacuum pump, a jet flow vacuum system and an electromagnetic vacuum system.

Detailed Description

The technical scheme of the patent is further explained in detail by combining the attached drawings and the embodiment.

As shown in fig. 1, the main working process of the energy-saving kitchen waste dehydration device is as follows: when the device is in a normal state, the valve 12 is opened, the garbage in the material box 1 is in a natural dehydration state at the moment, and water in the garbage enters the negative pressure dehydration box 5 after being filtered by the nylon cloth bag 4 and the porous plate 3 and is discharged through the drain pipe 13. When the material box 1 is full of garbage, the material box cover 2 is closed, the valve 12 is closed, the vacuum pump 6 is opened, the garbage in the material box 1 is in a negative pressure dehydration state at the moment, the vacuum pump 6 exhausts air into the negative pressure dehydration box 5 through the pneumatic hose 7, and partial moisture in the garbage in the material box 1 is pumped into the negative pressure dehydration box 5 under negative pressure and then is discharged through the drain pipe 13. When the air pressure value displayed in the vacuum meter 8 reaches a certain value, the negative pressure dehydration is finished, and the dehydrated garbage is taken out.

In order to conveniently feed and take out the garbage, a nylon cloth bag 4 is adopted to wrap the garbage in the material box 1.

A vacuum meter 8 is arranged on a pneumatic hose 7 of the negative pressure dewatering box 5 to control the negative pressure state, and the interlocking vacuum pump 6 realizes automatic operation.

Automatic drainage is realized by arranging a liquid level meter 10 in the negative pressure dewatering box 5 and interlocking a valve 12 on a drain pipe 13. Through liquid level control, the negative pressure state of the negative pressure dewatering box 5 is maintained, and normal dewatering of the kitchen waste is ensured during drainage.
