Filariasis line rail takes the end face of brush to be coated with second insulating layer, the end face that direct current zero curve rail takes brush far from second far from first
It is coated with third insulating layer, the material of the first insulating layer, second insulating layer and third insulating layer selects rubber in the present embodiment
Glue.
Referring to Fig. 2, it further includes Sewage treatment that a kind of cleaning systems, which include the cleaning device being mounted in medical trash elevator,
Device and contaminants-collecting apparatus.Waste water reclaiming device includes collecting tank 5, circulating pump 6 and several filter plates 51, whole filter plates
51 parallel settings are in collecting tank 5.Because elevator mainly collects the clinical waste of each floor in the process of movement, because
And only when medical trash elevator rests on the bottom, it can be to cabinet 1 after the clinical waste in cabinet 1 is cleaned up
It is cleaned, thus collecting tank 5 is fixed on the bottom of elevator.Return pipe is connected between collecting tank 5 and tank body 9
52, for collecting the liquid inside tank body 9.Be communicated with water inlet pipe 61 on collecting tank 5, water inlet pipe 61 and return pipe 52 respectively with
The connection of the two opposite end faces of collecting tank 5；And in order to further improve clean effect, the lower end of return pipe 52 and collecting tank 5
Portion's connection, and water inlet pipe 61 is connected to the upper end of collecting tank 5.In order to enable the liquid in return pipe 52 and water inlet pipe 61 can
Unidirectional flowing, thus check valve is provided on return pipe 52 and water inlet pipe 61.One end of water inlet pipe 61 and collecting tank 5 connect
Logical, the other end is connected to the end of liquid injecting pipeline 8, for the ease of the connection and disassembly of water inlet pipe 61 and liquid injecting pipeline 8, this implementation
Water inlet pipe 61 and liquid injecting pipeline 8 are threadedly coupled in example.Circulating pump 6, which is arranged on water inlet pipe 61, to be used for the liquid in collecting tank 5
It conveys and is recycled into liquid injecting pipeline 8.
Referring to Fig.1, contaminants-collecting apparatus includes several collection trolleies, and it is useless to collect medical treatment of the trolley for collecting each floor
Object is subsequently poured into cabinet 1.And cross-infection, thus the collection of each floor are generated when medical dirt in order to avoid collecting
Trolley individually works in each floor, to reduce the cross contamination generated during clinical waste is collected.
Motion process:
The clinical waste of the floor is collected first with the collection trolley in each floor, and is pushed into elevator for trolley is collected
It is waited at mouthful.
Start the work of the second actuator 21, using the second actuator of storage electrical energy drive 21 of storage battery with 2 turns of moving gear
It is dynamic, drive cabinet 1 to move upwards using the engagement of gear 2 and rack gear 3.During cabinet 1 moves upwards, first takes brush
It is contacted with direct current firewire rail, second takes brush and direct current zero curve rail to contact, so as to obtain electric energy and transmit electrical power to master
Then motor sends electric energy to second actuator 21 by main motor, to be rotated using the second actuator 21 with moving gear 2.
After the movement velocity of cabinet 1 tends towards stability, the connection circuit between storage battery and the second actuator 21 can be disconnected.
After cabinet 1 moves to the floor for needing to topple over clinical waste, when cabinet 1 moves to the protective device of the floor
Behind top, start the rotation of whole stepping motor synchronous of the floor, while by main motor and the second whole actuators 21
Between connection circuit disconnect, enable cabinet 1 to rest on the top of supporting block 4.
Then the clinical waste for collecting small car is poured into inside cabinet 1 after chamber door being opened, then according to above-mentioned side
Formula continues to move.
After elevator collects whole clinical wastes, cabinet 1 moves to the bottom of elevator, then by cabinet
Clinical waste in 1 all takes out.Return pipe 52 and tank body 9 are connected, while water inlet pipe 61 and liquid injecting pipeline 8 being connected,
Then for the work of starting circulating pump 6 by the Liquid extracting in collecting tank 5 into the inside of liquid injecting pipeline 8, liquid passes through rotating arm 81
With water spray pipe fitting 84, flowed out from apopore 841.Water inlet pipe 61 and liquid injection pipe are disconnected after carrying out preliminary spray to cabinet 1
Then the pure water that thimerosal and heating are successively passed through in liquid injecting pipeline 8 is thought in the connection in road 8, to realize to the comprehensive of cabinet 1
Cleaning.
Liquid in final cabinet 1 flows into inside tank body 9 through discharge outlet 91, and finally imports inside collecting tank 5.
