Description
Technical field
The invention belongs to spoil harmless treatment field, and in particular to a kind of biocontainment laboratory spoil without
Evilization processing equipment.
Background technology
With the development of animal husbandry, animal epidemic turns into the current subject matter for hindering animal husbandry development, animal epidemic
Preventing and treating is the major subjects of current animal husbandry, dies from the processing of the spoil of epidemic disease, is the key of epidemic preventing working, especially in fact
Apply the Animal Lab. of animal epidemic research and the experimental animal carcass of animal vaccine PRODUCTION TRAITS unit is dealt with improperly, can be direct
The diffusion of epidemic disease is caused, while causes environmental pollution, serious threat public safety, GB50447《Laboratory Animal Facility Building technology
Specification》Middle regulation, " negative pressure barrier environment facility should set harmless treatment facilities and equipment, defective work, cage tool, animal corpse
Body transports trial zone after answering harmless treatment " in biocontainment laboratory, typically spoil is entered using autoclaving
Row sterilizing, fills or hands over professional unit to burn after sterilizing, sterilization handles spoil due to that can not ensure bulk spoil
Internal whether thermal break-through in place, can not ensure the thorough of sterilizing, and labor intensity is big, and the spoil landfill after sterilizing can produce
The hidden danger of environmental pollution, burning method can produce a large amount of pernicious gases, pollute environment, with advances in technology, introduced a kind of alkali
Solution can effectively handle spoil, however, traditional alkaline hydrolysiss have following deficiency：

Reference picture 2 and Fig. 3, the place of the present embodiment biocontainment laboratory spoil innocent treatment equipment is described in detail
Reason process：
1st, load：When needing to handle spoil, screen opening hydraulic control system 35 can be operated by control system, passed through
Hydraulic control system driving hydraulic cylinder 16, cover 18 is opened, needing spoil to be processed to load in tank body 1, then passed through
Controller controls, and hydraulic control system 35 drives cover switch hydraulic cylinder 16 to return, and closes cover 18, then locks tooth form
Ring 20 engages with tooth form flange 23 and locks cover 18, while the second sealing gasket 22 seals to tank body 1 and cover 18.
2nd, pressurize is tested：After the completion of loading, the equipment advance pressurize test of the present embodiment, compressed air control valve 74 is beaten
Open, compressed air enters tank interior by compressed air interface 77, when pressure reaches the pressure value of the feedback of pressure transmitter 37
When reaching the test pressure of control system setting, compressed air control valve 74 is closed, and starts pressurize, the dwell time reset
It is interior, when the pressure that first pressure transmitter 37 feeds back drops to below set test pressure value, test not by system
Alarm, is prompted to overhaul of the equipments；If the pressure that first pressure transmitter 37 feeds back is higher than the test pressure value set, test
By the way that exhaust-valve 36 automatically opens up, and gives tank body pressure release, pressure release are automatic after terminating to close.
3rd, alkali lye is added：After the completion of pressurize test, alkali lye control valve 73 is opened, and alkali lye enters tank by alkali lye charging aperture 76
Internal portion, control system is controlled by weighing sensor 25 to entering the alkali lye amount inside tank body 1, when alkali lye amount and animal
After the ratio of corpse amount reaches preset value, alkali lye control valve 73 is closed automatically, is added alkali lye and is terminated.
4th, heat up：After the completion of adding alkali, steam control valve 41 is opened, and steam is right into coil pipe chuck 2 by steam inlet 44
Tank body heats, and condensed water discharges by condensing water control valve 70 and drain valve 69 from condensed water elimination pipeline 56, and system passes through the
One pressure transmitter 37, second pressure transmitter 39 and temperature transmitter 71 automatically control to heating process, when temperature reaches
During to control system preset value, system starts to maintain temperature, and now spoil is decomposed, while stirring motor 34 starts, annular
Agitator 27 is run, and accelerates whipping process.
5th, pressure release：Processing time reach setting time after, from visor lamp 19 can from disposition, confirm animal corpse
After body is fully processed, steam control valve 41, condensation water valve 70 are closed, and evaporation control valve 40 and exhaust-valve 43 are opened, and are made in tank
Steam is discharged by condenser 64, and pressure release is carried out to system, while cooling water water inlet control valve 60 and water-returning control valve 58 are opened,

Gao Shi, condensation water drainage control valve 63 are opened, and condensate pump 62 starts by condensing the draining of water outlet 57, the relatively low time control of water level
Valve 63 processed is closed, and condensate pump 62 stops, and after pressure release terminates, all valves are closed.
6th, nertralizer is added：After pressure release terminates, eliminating smell agent control valve 72 is opened, and nertralizer is automatic by eliminating smell agent charging aperture 75
Open, add nertralizer, after reaching setting value by the amount of the detection addition nertralizer of weighing sensor 25, eliminating smell agent control valve 72
Close, nertralizer, which adds, to be terminated.
7th, dry：After nertralizer addition terminates, steam control valve 41, condensation water valve 70 are again turned on heating tank body, and
Temperature in tank is controlled to setting value, to be evaporated to the moisture content in the product after processing, while evaporation control valve 40, cooling water enter
Water control valve 60 and water-returning control valve 58 are again turned on, and steam in tank is cooled into condensate by condenser 64, are worked as liquid level
When switch detects that the water level of condenser 64 is higher, condensation water drainage control valve 63 is opened, and condensate pump 62 starts and passes through condensation
The draining of water outlet 57, condensation water drainage control valve 63 is closed when water level is relatively low, and condensate pump 62 stops.
8th, cool down：Weighing sensor 25 detects in real time, and after weight is reduced to setting value in tank, evaporation terminates, all valves
Close, cooling water water inlet control valve 59 and water-returning control valve 42 are opened, remaining objects in tank cooled down, when temperature is low in tank
After the exhaust temperature of setting, cooling water water supply control valve 59 and cooling water water-returning control valve 42 are closed, and cooling terminates.
9th, discharge：After cooling terminates, bottom valve 32, exhaust-control valve 68 are opened, and compressed air control valve 74 is opened, in tank
Residue is discharged into dolly 66 by floss hole 67.
10th, clean：Detected according to weighing sensor 25, after residual drain terminates in tank, exhaust-control valve 68, compression are empty
Gas control valve 74 is closed, and city water control valve 51, clear control valve 38 are opened, and running water passes through running water inlet 47 and heater 52
Tank body is cleaned into tank body, while steam control valve 49 and condensation water control valve 53 are opened, steam passes through steam inlet
50 enter heat exchanger to tap water heating, are cleaned with high-temperature water, ensure cleaning performance, the present embodiment can pass through temperature transmitter 48
The temperature of rinse water is automatically controlled, condensed water is discharged by drain valve 54 from condensing water conduit 56, and draining control is cleaned during cleaning
Valve 65 is opened, and rinse water is discharged by cleaning discharge outlet 55, and after scavenging period reaches setting time, cleaning terminates, all valves
Close, whole workflow terminates.
