Abstract

The concentrated draining anti-freezing train toilet is developed on the basis of available washroom and toilet. It has concentrated draining pipe installed inside floor and the concentrated draining pipe is connected to the drain pipe and floor drain of both washroom and toilet and has outlet connected to toilet and is provided with electrothermal belt and heat insulating material. The sewage from both washroom and toilet is drained from toilet and there is temporary sewage storing apparatus at the outlet of the concentrated draining pipe, so that the present invention solves the problem of contaminating train chassis. Owing to the electrothermal belt and heat insulating material, the present invention avoids the freezing and jamming of the draining pipe. The present invention may be used to replace available train toilet.

Description

Concentrate blowdown antifreezing type train sanitary accomodation

Technical field

This patent relates to the concentrated blowdown antifreezing type sanitary fixture of the sanitary accomodation, particularly described sanitary accomodation that comprise on a kind of passenger train that washing room and lavatory are formed.The sanitary fixture field that belongs to rolling stock.

Background technology

The sanitary accomodation that washing room that disposes on the existing train and lavatory are formed, Lower hose wherein all is the through type drain hose that directly extends to the car body below from the top down, generally speaking, washing room has two drain hoses to lead under the railway carriage chassis, one is the drain hose of wash basin, one is the drain hose of floor drain, also there are the drain hose of a hand basin and the blow-off pipe of closet in the lavatory, bull draining blow-off pipe appears, cause the ight soil and the sewage that are in operation, float in the air with the wind because of the speed of a motor vehicle is very fast, making on the train chassis is sewage everywhere, corrodes steel body at the bottom of the car all the year round, forms ice cube especially in the winter time, inspector inconvenience inspection is safeguarded, have a strong impact on and check on the quality and potential safety hazard takes place easily.Simultaneously, the bull drain hose is easy to freeze in the winter time stop up, and can cause the sewage in the sanitary accomodation to overflow, and has a strong impact on the service quality of train.

Summary of the invention

The order of this patent is to have problem such as suave and obstructions of freezing of sewage for the bull through type drain hose that solves existing train washing room and lavatory, design a kind of with sewage and ight soil all from the concentrated blowdown antifreezing type train sanitary accomodation of closet discharge.

The concentrated blowdown antifreezing type train sanitary accomodation of this patent, its structure mainly comprises washing room and floor, wash basin and Lower hose, floor drain, lavatory and floor, closet, hand basin and Lower hose, also include concentrated drainage pipe and ribbon heater simultaneously, described concentrated drainage pipe is contained in the floor, the ribbon heater is contained in the outer side edges of concentrated drainage pipe, wash basin Lower hose and floor drain and hand basin Lower hose etc. all with concentrated drainage pipe UNICOM, the water outlet of concentrated drainage pipe and closet UNICOM.For the ease of removing foreign material, described concentrated drainage pipe comprises drainage channel and cover plate, and described drainage channel can be installed in washing room floor and the toilet floor in first segmentation, and then interconnects and form, and cover plate and drainage channel match and cover on drainage channel.In order to help heat-preserving anti-freezing, can outside concentrated drainage pipe and ribbon heater, be surrounded by heat-insulation layer, described ribbon heater can be selected the cryogenic stage self-regulating ribbon heater for use.

The concentrated blowdown antifreezing type train sanitary accomodation of this patent, owing to cancelled the through type drain hose of the bull that is distributed on the train chassis, with the concentrated drainage pipe sewage and ight soil are all discharged from closet, thoroughly having solved suave with the wind the making on the train chassis of the sewage that causes because of the bull drain hose is the problem of sewage everywhere.Because of the concentrated drainage tube wall is equipped with ribbon heater and warm material, make the temperature controlled above freezing of concentrated drainage pipe again, the obstruction of can not freezing winter.Have advantages such as reasonable in design, sanitation and hygiene, resistance to frost be good, temporary collection formula electro heat blowdown apparatus is installed at the following mouth of a river of lavatory closet again, can accomplish quantitative automatic discharging dirt sewage.It is the renewal product of existing train sanitary accomodation.

Description of drawings

Accompanying drawing 1 is the structural representation of an embodiment in this patent;

Accompanying drawing 2 is that A-A in the accompanying drawing 1 is to structural representation;

Accompanying drawing 3 is that B-B in the accompanying drawing 1 is to structural representation.

The specific embodiment

Referring to accompanying drawing, 1 in the accompanying drawing 1 is the washing room wall, the 2nd, and the water inlet of the wash basin Lower hose of concentrated drainage pipe, the 3rd, the wash basin Lower hose, the 4th, wash basin, 5 are provided in a side of the concentrated drainage pipe in the washing room floor, the 6th, Wash Units, the 7th, the washing room floor, the 9th, the water inlet of the hand basin Lower hose of concentrated drainage pipe, 10 are provided in a side of the concentrated drainage pipe in the toilet floor, the 11st, toilet floor, the 12nd, closet, the 13rd, lavatory wall.Accompanying drawing 2 is that A-A in the accompanying drawing 1 is to structural representation, among the figure 21 is drainage channels of concentrated drainage pipe 5, the 22nd, the cover plate of drainage channel 21, the 23rd, the ribbon heater, the 24th, the drainage channel of concentrated drainage pipe 10, the 25th, the cover plate of drainage channel 24, the 26th, the temporary collection formula electro heat blowdown apparatus of installing at the following mouth of a river of closet 12.Accompanying drawing 3 be B-B in the accompanying drawing 1 to structural representation, 31 among the figure is heat-insulation layers.Described concentrated drainage pipe 5 and 10 is contained in respectively in

floor

7 and 11, ribbon heater 23 is contained in the outer side edges of concentrated drainage pipe 5 and 10, wash basin Lower hose 3 and floor drain 8 and hand basin Lower hose etc. all with concentrated drainage pipe UNICOM, the water outlet of concentrated drainage pipe and closet 12 UNICOMs.For the ease of producing and remove foreign material, described concentrated drainage pipe 5 and 10 comprises

drainage channel

21,24 and

cover plate

22,25 respectively, described drainage channel can be installed in washing room floor and the toilet floor in first segmentation, and then interconnects and form, and cover plate and drainage channel match and cover on drainage channel.Open cover plate and can remove foreign material in the drainage channel.In order to help heat-preserving anti-freezing, can outside concentrated drainage pipe and ribbon heater, be surrounded by heat-insulation layer, described ribbon heater can be selected the cryogenic stage self-regulating ribbon heater for use.Because this temperature self controlled electrically-heated carries product has good temperature automatically controlled performance, do not freeze so can make the concentrated drainage pipe maintain design temperature above freezing.A temporary collection formula electro heat blowdown apparatus 26 is installed at the following mouth of a river at closet 12, can accomplish quantitative automatic discharging dirt sewage, makes it better effects if.It is the renewal product of existing train sanitary accomodation.
