Liquid level.In order to ensure hopper 3 can reliably stop at position after the lifting, so that it is guaranteed that sheeting everything goes well with your work carries out,
It is both provided with non-return mechanism on each driving wheel 6 in the present embodiment, each non-return mechanism includes：The driving wheel 6 uses
62 integral structure of sprocket wheel 61 and ratchet, drive chain 507 are engaged on the sprocket wheel 61 of driving wheel 6, the ratchet 62 of driving wheel 6 and one
Pawl 63 matches, and 63 elasticity of pawl is hinged and connected on shell 501 and elastic block is between two adjacent teeth of ratchet 62, is driven
When the free end of dynamic chain 507 pulls downward on, pawl 63 will not hinder ratchet 62 to rotate, when the free end of drive chain 507 stops fortune
When dynamic, the elastic block of pawl 63 is on ratchet 62, so as to prevent driving wheel 6 from rotating backward.In addition, for the ease of hopper 503
It resets, the pawl 63 per side is respectively connected with cylinder, and the piston rod of cylinder, which elongates or shortens, can drive pawl 73 and corresponding ratchet
62 are separated or return back to state of the block on ratchet 62 again, when pawl 63 is separated with corresponding ratchet 62, hopper 503
It can move downward under gravity.Triple effect flaker 332, two is imitated the effect flaker 132 of flaker 232 and one and is all made of
The purpose for stating structure is：Once because of scram, the complete sheeting of lye is realized by way of promoting hopper, this is avoided that dense
The case where lye of high concentration after contracting wastes, and can effectively avoid the waste of water resource, the workload of staff
Greatly reduce, to reduce cost for solid caustic soda production.Traditional flaker is since hopper is fixed, and the liquid level of lye can not in hopper
Operating fluid level is remained at, i.e. liquid level in hopper is constantly reduced, and lye can not be adhered to drum surface, to carry out
Sheeting, the lye in hopper can only be discharged directly from drain pipe 504, this not only causes the waste of high-concentration alkali liquor, whole
A flaker also needs to be cleaned using a large amount of clear water, to cause the waste of water resource, while also greatly increasing work
The workload of people.
Operation principle is as follows：Raw material lye in lye tank (vat) 4 uses mass concentration for 50% 50 liquid caustic soda, the entrance of 50 liquid caustic soda
Triple effect concentrates in sheeting mechanism 3, is completed after triple effect evaporator 31 and the evaporation of triple effect separator 32 and separation successively dense for the first time
Contracting is controlled from the mass concentration of the lye after the first time concentration that triple effect separator efferent duct 36 exports 50%~65%, including
65%.Lye after concentrating for the first time is entered to through two effect feed pipes 24 in two effects concentration sheeting mechanism 2, after concentrating for the first time
Lye is completed second after 2nd effect evaporator 21 and two imitates the evaporation of separator 22 and separation successively and is concentrated, defeated from two effect separators
The mass concentration of lye after second of concentration that outlet pipe 26 exports is controlled 65%~80%, including 80%.After second concentrates
Lye is entered to through an effect feed pipe 14 in effect concentration sheeting mechanism 1, and the lye after second of concentration is evaporated through an effect successively
Device 11 and one is completed to concentrate for the third time after imitating the evaporation of separator 12 and separation, from the third time of 16 output of an effect separator efferent duct
The mass concentration of lye after concentration is controlled 80% or more.It, can be according to the concentration of target product, phase in actual production process
It controls the concentration of the lye after concentration each time with answering, 50%~99% including 99% times can be thus realized according to customer demand
It anticipates a kind of production of concentration piece alkali.
In order to be better described, names three examples and be further described in detail.
One, when only needing quality of production concentration in the piece alkali of 80% one of the above concentration.361 He of triple effect sheeting control valve
Two effect sheeting control valves 261 are in closed state, and the two effect effect inlet control valves 142 of inlet control valves 242 and one, which are in, to be beaten
Open state, 50 liquid caustic soda in such lye tank (vat) 4 carry out first time concentration successively, second of concentration, third time concentrate, and complete third
The lye of secondary concentration enters to an effect distribution tank 131 from an effect separator efferent duct 16, and the lye in an effect distribution tank 131 enters
Sheeting is carried out in an effect flaker 132, the piece alkali of formation enters an effect solid caustic soda from the solid caustic soda output channel of an effect flaker 132
It is packaged into bag in packing machine 133, is exported outward at the piece alkali of bag.
Two, the quality of production a concentration of 80% or more and mass concentration are between 65%~80% when needing simultaneously, including 80%
Two kinds of concentration piece alkali when.Triple effect sheeting control valve 361 is closed, and two effect sheeting control valves 261 are in open shape
State, two effect inlet control valves 242 and one imitate inlet control valve 142 and are in opening state, pass through two effect sheeting control valve of control
261 and one imitate the aperture of inlet control valve 142, and inlet control valve 142 is imitated by two effect sheeting control valves 261 and one to control
Flux of alkaline liquor.After raw material lye carries out first, second concentration, the lye of second of concentration is completed, a part enters two effects
Flaker 232 carries out sheeting, and another part enters an effect and concentrates progress third time concentration in sheeting mechanism 1.Two effect flakers 232
The piece alkali that sheeting generates, which enters in two effect packing machines 232, is packaged into bag, and the piece alkali for being packaged into bag exports outward.Into an effect concentration
The lye after third time concentration is carried out in sheeting mechanism 1 imitates the progress sheeting of flaker 132, shape through an effect distribution tank 131, one successively
At piece alkali enter in an effect solid caustic soda packing machine 133 from the solid caustic soda output channel of an effect flaker 132 and be packaged into bag, at the piece of bag
Alkali exports outward.
