Description

Kitchen waste collecting and pumping device

Technical Field

The application relates to the field of collection and conveying, in particular to a kitchen waste collection and pumping device.

Background

When the ship runs on the sea, the kitchen waste generated on the ship cannot be discharged to the sea at will. In the sea area where direct discharge is impossible, the kitchen waste needs to be crushed and collected into a collection tank. When the ship travels to a dischargeable sea area, the kitchen waste in the collection tank needs to be discharged to a corresponding position through the conveying device.

In the prior art, a screw pump is generally adopted to convey the kitchen waste in the collection tank to the outside of a ship. However, such a conveying device has at least the following technical problems:

1. compared with dry garbage, the water content of the kitchen garbage is uncertain, and the viscosity of some parts is high. The screw pump is sensitive to viscosity, and the working principle of the screw pump is that materials are conveyed through the change of a space gap between the rotor and the stator, so that the screw pump is high in conveying capacity for the materials with high water content and good fluidity, and conversely, the screw pump is low in water content, high in viscosity and poor in fluidity, and the conveying capacity of the materials with low water content and high viscosity can be obviously reduced or even loses efficacy. When the viscosity of the material is high, the material is easy to adhere to the side wall of the collecting tank, and the emptying of the collecting tank is influenced.

2. The particle size of the kitchen waste is very different, but the distance between the rotor and the stator of the screw pump is not large enough, so that particles with the diameter of more than 10mm are difficult to suck.

3. Metal particles may be mixed into the kitchen waste. The stator of the screw pump is usually made of non-metallic materials such as plastics, and when metal particles are sucked, garbage can scratch or pierce the stator, so that the service life is shortened.

Therefore, those skilled in the art are devoted to developing a kitchen waste collecting and pumping device to solve the technical problems in the prior art.

Detailed Description

The technical contents of the preferred embodiments of the present application will be more clearly understood and appreciated by referring to the drawings attached to the specification. The present application may be embodied in many different forms of embodiments and should not be construed as limited to the embodiments set forth herein.

In the drawings, elements that are structurally identical are represented by like reference numerals, and elements that are structurally or functionally similar in each instance are represented by like reference numerals. The size and thickness of each component shown in the drawings are arbitrarily illustrated, and the size and thickness of each component are not limited in the present application. The thickness of the components has been exaggerated in some places in the drawings where appropriate for clarity of illustration.

As shown in fig. 1 and fig. 2, the present embodiment provides a kitchen waste collection and pumping device, which includes a collection tank 1 and a delivery pump 2. The transfer pump 2 is a centrifugal pump. The feed pump 2 includes a feed pump motor 21, a feed tube 22, and a pump head 23. The delivery pipe 22 and the pump head 23 are disposed inside the collecting tank 1, and the delivery pump motor 21 is disposed above the collecting tank 1 and is used for driving the pump head 23 to rotate. The pump head 23 is provided with an open impeller, and when the pump head 23 is driven by the conveying pump motor 21 to rotate, the open impeller generates centrifugal force to suck the materials in the collecting tank 1 out through the conveying pipe 22. The conveying pipe 22 is connected with the inline pipe 5, and the material is discharged to the outside of the collection tank 1 through the conveying pipe 22 and the inline pipe 5. The pump head 23 is made of a metal material.

The material enters the collecting tank 1 through a bin penetrating pipe. The catchment tank 1 is arranged as a closed structure. In order to prevent the potential safety hazard caused by gas generated in the material storage process and increased pressure due to gas expansion, the ventilation pipe 3 is arranged in the embodiment. The gas-permeable pipe 3 is arranged at the upper part of the collecting tank 1 and can be opened to release excessive gas when needed. Preferably, an activated carbon adsorption device is arranged in the vent pipe 3 to clean gas and prevent odor from diffusing. A level sensor 8 is also arranged inside the collecting tank 1. The level sensor 8 is used for monitoring the level position of the material in the collection tank 1 and monitoring the storage space remaining in the collection tank 1. The inner wall of the collecting tank 1 is provided with a non-stick material, and preferably, the inner wall of the collecting tank 1 is provided with a tetrafluoro coating to prevent materials from being attached to the inner wall of the collecting tank 1 and influencing the conveying of the materials. The collection tank 1 and the entire apparatus are fixed to the deck by means of a base 4. The collecting tank 1 is also provided with a fresh water cleaning port 5, and the collecting tank 1, the electric valve 7 and the straight exhaust pipe 5 can be cleaned regularly.

The working principle of the embodiment is that a pump head 23 with an open impeller is driven to rotate at a high speed by a delivery pump motor 21, and kitchen waste is sucked into the pump head 23 by centrifugal force generated by the impeller and then is sent out of the collection tank 1 through a delivery pipe 22. Due to the centrifugal suction, the pump head 23 is less sensitive to changes in the viscosity of the material, and its transport capacity is not affected by the viscosity. The gap between the impeller and the pump housing is relatively large, so that refuse particles larger than 10mm can be smoothly sucked into the pump head 23. Since the pump head 23 is made of a metal material, the inclusion of metal in the trash has substantially no effect on the pump head 23.

The foregoing detailed description of the preferred embodiments of the present application has been presented. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the present teachings without departing from the inventive concept. Therefore, the technical solutions that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the prior art according to the concepts of the present application should be within the scope of protection determined by the claims.
