Technical field

The present invention relates to a kind of liquid separating appts, more specifically to a kind of be used to make oil and/or grease and moisture from device.

Background technology

In some industry especially grocery trade, need before entering sewerage, from waste water, isolate Jiang Shui liquid fat, fat and oily.Waste water for example can be from being used to clean the cleaning device discharge of tableware and mess kit.If grease and fat solidify in sewerage, the mediation of need spending then can appear stopping up.

In addition, in many places, there is the motion that recycles grease and oil.

In Fig. 1 a and 1b, demonstrate the sort of commercially available separator described in the European patent EP 890381B1 substantially.Fig. 1 a shows the outer perspective view of separator 10.Receive effluent (effluent) (immiscible liquid that includes two or more different densities is generally the water that has been mingled with oil, grease, dissolved fat and other particle) at inlet 12 places that the passage that enters shell 14 (comprising detachable lid 15) is provided.The probe-type heater that use links to each other with electrical connections heats this effluent.As described below, these immiscible liquids are separated in shell 14, and materials of low density (for example, grease and oil) is arranged in the container 18.High-density matter (for example water) is discharged from delivery port 20.Debris accumulation is in the bottom of shell 14.Can export 2 by chip regularly discharges this chip.

In conjunction with Fig. 1 b (and be cited as a reference EP 890381 B1) operation of this separator 10 is described in detail now.Fig. 1 b demonstrates the side sectional view of this separator 10.Define a coarse filtration chamber 24 at shell 14 with between the control panel 25 that extends on the whole width of shell.By entering the mouth 12 when entering this coarse filtration chamber 24, it wears filter basket 26 (showing in greater detail out) in Fig. 2 at effluent, and this filter basket filters out for example undissolved fat of solid particle and other food particle.

After wearing filter basket 26, this effluent enters the split cavity 28 that is limited by control panel 25, control panel 30 (it extends), top board 32 and shell 14 bottoms on the whole width of shell.Split cavity has two outlets: (1) is by ball-cock assembly 34; And (2) are by being arranged on the passage 36 between control panel 30 bottoms and shell 14 bottoms.Top board 32 makes progress angled towards control panel 30 from the bottom of control panel 25.

The weir plate 38 that extends on the whole width of shell defines water (high density liquid) discharge chamber 40 with control panel 30 and shell 14.Outlet 20 runs through the shell setting.

In the operation, when effluent entered split cavity 28, low density liquid (fats/oils) rose.The flow velocity that passes this split cavity 28 so is provided with, make low density liquid can with moisture from and upwards float on the surface of water, it is accommodated in inclined roof panels 32 belows there.

Inclined roof panels 32 forces low density liquid to be accumulated in to lead to the porch of ball-cock assembly 34.In Fig. 4, show out ball-cock assembly 34 in greater detail.This ball-cock assembly 34 has used a ball that swims between high density liquid and the low density liquid at the interface.When high density liquid arrived predetermined altitude, this ball rose to and can make from the mobile height that stop of split cavity 28 to container 18.

When current passed this separator 10, it must rise to the top at weir plate 38 tops so that discharge.Therefore, the water in the split cavity 28 attempts to rise to roughly the same height.Because the top of split cavity 28 is lower than the top of weir plate 38, so the hydrostatic pressure that water makes progress is passed valve 34 with promoting to be positioned at the fats/oils of locating at split cavity 28 tops.But water can not pass valve 34, because this float valve will stop it to pass through.Therefore, in case force the fats/oils of all separation to leave split cavity, valve closes maintenance up to having accumulated more fats/oils.

The water that separates passes passage 36, crosses weir plate 38 and discharges from exporting 20.Chip in the water will accumulate in the bottom of shell 14, can not rise and cross weir plate 38.Can regularly open the chip valve 22 that is located at shell 14 bottoms, the current of discharging from valve can be gone out chip.

In many uses field of this separator 10 especially grocery trade, can suppose that the employee of this separator of operation and maintenance is mobile relatively between each employer.Therefore, the operation and maintenance aspect of this separator must make that being unfamiliar with personnel grasps easily.If for example the affairs that each building block such as the ball-cock assembly of separator regularly cleaned are operated improperly and will be caused adverse consequences, for example make water enter oil/oil and fat vessel or oil/grease flows out from exporting 20.

Also have, preferably improve the flow velocity that liquid passes split cavity because oil and grease be originally viscosity and be accumulated on the crust easily.

Therefore, the improved separator of industrial needs.

The specific embodiment

To understand the present invention better with reference to accompanying drawing 1-11, wherein the like of each accompanying drawing uses similar label.

Fig. 2 shows the filter basket 26 of prior art.This filter basket has a front (at inlet 12 places facing to shell) and the back side (facing to control panel 25), equally has bottom the frame it on and bores a hole 50.Because positive and shell 14 be relative to flush and the back side flushes relatively with control panel 25, and not perforation of end, thus nearly all effluent all stream pass hole bottom this filter basket.Through after a while, food particle will be accumulated on the bottom of this filter basket 26, thereby seriously limit inflow split cavity 28.

Other problem relates to the dismounting and the replacing of filter basket 26.Prior art has been used handle 52, and this handle end is passed the hole on this filter basket either side.This filter basket 26 has the edge of a wing 54 on either side; These edges of a wing 54 rest at usually on the propclip 56 that forms on the coarse filtration chamber 24 shell either sides.In order when removing or changing the filter basket, to hold the exposed end of handle 52, in propclip 56, be formed with slit 58, this slit 58 can be passed in the end of handle.

During operation, these slits 58 have hindered sealing fully between the edge of a wing 54 and the propclip 56.Some food particles in the effluent can pass these slits 58, thereby walk around this filter basket 26.Food particle also can lead between filter basket leading edge and the outer body 14 and filter basket trailing edge and control panel 25 between close clearance.The food particle that enters split cavity 28 too much can stop up ball-cock assembly 34, thereby causes water to enter oily collection chamber 18.

Fig. 3 a to 3d shows perspective view, top view, front cross sectional view and the side sectional view that improves filter basket 60 respectively.This improvement filter basket has improved effective effluent flow velocity, has avoided the solid particle in the effluent around the filter basket filter mechanism, and has promoted the separation of effluent in the split cavity 28.

Different with the vertical side of filtering basket 26 is that taper filter basket 60 has the tapered side that tilts to leave shell 14 and control panel 25.In addition, all there is perforation all four sides.Therefore, bigger filter basket surface area separates with pinch wall so that the more effectively mobile filter basket 60 of wearing.Because the shared area in hole 62 is bigger,, and can influence effluent and flow and pass this filter basket so these holes 62 can have littler diameter.In the prior art, the diameter in hole 50 is approximately 11/64 inch, and the diameter in hole 62 can be approximately 1/16 inch (0.15875cm).This makes this filter basket 60 can collect littler particle so that carry out more effective coarse filtration.In addition, before turning this filter basket, needs can collect more chip, even because also can filter effluent when should filter basket being capped in the bottom with remaining valid.

Another improvements are to have increased sloping baffle 64 on filter basket 60.This baffle plate 64 makes water from the 12 bottom deflections towards filter basket 60 that enter the mouth.Otch 64a in the baffle plate 64 is facing to inlet 12.When effluent entered coarse filtration chamber 24, baffle plate drove oil and grease with effluent guiding downwards with help below control panel 25.In addition, when effluent impingement baffles 64, it is driven passes one deck oil, and this helps to make chemical emulsification liquid saturated, thereby it is fuel-displaced to make that these emulsions discharge.

The handle 68 of filter basket 60 is installed on the top of baffle plate 64.Because handle does not stretch out from the side of filter basket 60, so no longer need the slit 58 shown in Fig. 2.

Under the situation that is added with baffle plate 64, importantly this filter basket 60 want correct orientation (thereby this baffle plate make effluent downwards rather than upward deflect).Therefore changing filter basket 60 can cause the operation of separator 10 that problem is arranged because of carelessness.In order to prevent the dislocation replacing, filter basket 60 has asymmetric edge of a wing 54a and 54b.As shown in Fig. 3 a-d, edge of a wing 54a is wideer than 54b, and propclip 56a is wideer than 56b.If filter basket 60 is reversed replacing, not matching between propclip 56a-b and the edge of a wing 54a-b will make filter basket can not correctly take one's seat (and lid can not be closed).This will remind operating personnel will filter basket oppositely.Front and back edge of a wing 54c and 54d form a whole lip, and it surrounds filter basket 60 fully so that sealing fully.

Fig. 4 demonstration is used in a kind of ball-cock assembly 34 of the prior art.This ball-cock assembly 34 is included in the ball 70 in the shell 72.This ball 70 remains in the shell 72 by grid 74.Insert 76 comprises and is used for above ball 70 exit portion 79 that is communicated with oil/oil and fat vessel 18 with the part 78 and being used for of matching that shell 72 cooperates.In insert 76, be formed with the passage 80 that runs through match part 78 and exit portion 79, and have a tapered opening 82 at the place, end of this passage 80.Passage 80 is connected with outlet 84.O shape ring 86 is sealing match part 78 and shell 72.As mentioned above, ball 70 is designed to swim between two kinds of immiscible liquids (for example water and oil/grease) at the interface.When rising on the water, oil/grease is pushed in the passage 80, and it is discharged in oil/oil and fat vessel 18 by exporting 84 there.In case all low density liquids (oil/grease) are advanced passage 80, then ball 70 is resisted against in the tapered opening 82, seals this passage thus.Like this, have only low density liquid can pass through passage 80.

Because oil and grease will pass passage 80 and 84 and lead to oil/oil and fat vessel 18, so must regularly clean these passages 80 and 84 so that remove coagulated substance.For this reason, be inserted into passage 80 from the top brush or be inserted into from the side in the passage 84, and adopt scraping motion up and down to remove the oil/grease that solidifies in passage 80.In this cleaning course, the part that matches 78 displacement from shell 72 easily, thus cause valve 34 to be out of order.

The side sectional view that shows the improvement ball-cock assembly 90 that can replace ball-cock assembly 34 uses among Fig. 5 a.This ball-cock assembly 90 comprises having two parts 78 that match of stretching out locking pin 92.Shell 72 comprises two vertical channels 94, and they form the L shaped pin 92 that is used for holding with respective horizontal passage 96.Pin 92 is aimed at vertical channel 94 by making, the part that will match 78 is inserted in the shell 72 up to pin 92 and arrives the end of vertical channels 94, then this pin is rotated matching in horizontal channel 96 partly to be locked in the shell 72, thereby the part 78 that matches is bonded in the shell 72.

Fig. 5 b shows the perspective view of shell 72, has showed vertical channel 94 and horizontal channel 96.Fig. 5 c shows the insert 76 in the locked position that is in the shell 72.

Another problem relevant with ball-cock assembly 34 is the problem that can occur under ball 70 is bonded at situation on the part 82 that matches.Because oil/grease will apply two surfaces during the normal running of separator 10, this problem may appear.

Fig. 6 a demonstration need not to use the valve of ball float to replace the schematic diagram of embodiment.In Fig. 6 a, sensor 100 can detect two kinds of interface locations between the immiscible liquid.When this interface had arrived predetermined altitude, this sensor transmitted control signal to actuator 102.In response to this control signal, actuator cuts out the valve 104 that is used for controlling flow between oil/grease inlet 106 and the oil/grease outlet 108.

Fig. 6 b to 6d shows three kinds of valves (also can use other valve types) that can be applied to valve 104.Fig. 6 b shows the side sectional view of butterfly valve 110.Operate butterfly valve by rotary disk 114 in cylinder blanket 112.When the surface of disk 114 was parallel to the axis alignment of cylinder blanket, valve 110 was in open mode; When the surface of disk 114 during in the axis normal of cylinder blanket 112, this valve 110 is in closed condition.

Fig. 6 c shows the side sectional view of gate valve 120.In gate valve, gate 122 is arranged in the pipe 124 in case fluid stopping is moving or extract out allowing from pipe 124 and to flow.

Fig. 6 d shows the side sectional view (not obscuring with ball-cock assembly 34) of ball valve 130.This ball valve is combined with a spheroid 132, and the central authorities of passing this spheroid are provided with a cylindrical bore 134.Punctual with inlet 136 and 138 pairs of outlets when this duct, liquid can flow to outlet from inlet.When duct 134 turned to it not with position that inlet 136 and outlet 138 are communicated with, liquid no longer can pass this valve.

This ball valve 130 is the preferred embodiments of the invention, because valve is wiped the oil/grease that solidifies at entrance and exit place off easily at the rotating operation that opens and closes between the position.Therefore this valve in a way can automatically cleaning.

Fig. 7 a shows the improvement that this separator 10 is done, and the flowing of liquid (and chip) that is used for improving in split cavity inside operated so that improve.At first, the surface of the interior example of shell 14 and control panel 25, top board 32, control panel 30 and weir plate 38 can be coated with polytetrafluorethylecoatings coatings 39 or another kind of non-sticking lining 39, in order to improve friction and the adhesive force between mobile and reduction oil/grease/chip and these surfaces.

In addition, Fig. 7 a shows heating the improvement of liquid in the split cavity 28 especially.In the prior art, adopted the probe-type heating element heater.There are some problems in this.At first, heater is installed on the outside of unit, and it may be run into by the employee because of carelessness there, even is bumped pine.The second, the surface area of heater is less relatively, so heat is concentrated.

In Fig. 7 a, show the several alternatives that are used for heating split cavity 28 liquid.These replacement methods can be used alone or in combination.First alternative has been used the heating blanket 140 that is arranged on the outer casing bottom 14.Can eliminate any outstanding shell that is used for this heater like this, and can heat bigger surface area, make the temperature on split cavity 28 keep constant relatively.

Second alternative has used eddy-current heating to heat top board 32 and/or valve 34.Because top board 32 contacts with valve 34 and oil/grease are almost constant, thus these parts of eddy-current heating can be passed through, thus provide heat to make oil/grease remain liquid as far as possible most effectively.Can be used in combination with heating blanket 140 top board 32 and/or valve 34 eddy-current heating.

In addition, in Fig. 7 a, adopt self closing valve 147 as the chip valve.Manually make this valve 147 stay open the sufficiently long time (being typically about 10 seconds) in chamber so that chip extrudes under the hydraulic pressure effect, in case and operating personnel's hand take away from valve handle, this valve will be closed immediately.Prevented from like this to operate this device, made effluent can directly flow out the chip valve in the situation of chip valve open; Cause overheated heater and burning and/or make that oil is overheated and smolder.

Fig. 7 a, 7b and 7c show top and the lower seals that is used in this improved separator.On the top of the periphery of shell 14 and control panel 25 and 30, form top seal 142, thereby form sealing continuously.In preferred embodiments, seal 142 is installed on shell 14 and the control panel according to the mode machinery shown in Fig. 7 c.In Fig. 7 c, encapsulant preferably is fixed on the edge and control panel 25 and 30 of shell 14 by mechanical grip mechanism 144 with hollow neoprene pipe or similar flexible hollow form of tubes.In the embodiment illustrated, this mechanical grip mechanism comprises tooth 146, and these teeth will catch these edges to form firm mechanical cohesive bond on being pushed to shell edge the time.Any gap between material bands should be filled with sealed compound.

In operation, top seal 142 can be born sizable hydraulic pressure, and has only the weight of lid 15 that its maintenance is contacted with seal 142.Therefore, if current 20 pour in by entering the mouth, then water remains in the shell 14, can not overflow the internal chamber 148 that enters shell 14 from coarse filtration chamber 24 or water discharge chamber 40, and it can become and become sour there.

Prior art mechanism has used by single-coated foam and has been fixed on compression foam on the lid lower limb, thereby and cover anchor clamps and lid is remained on to form on the main body seal by using.Make the user be difficult to touch this unit like this.Also have, clamped lid has hindered operating personnel and has correctly safeguarded this unit.

Another lower seals 149 is installed in around the outer casing bottom edge.Also have, lower seals 149 preferred as Fig. 7 c as shown in use mechanical grip mechanism 144 be fixed on hollow neoprene form of tubes on the edge of shell 14.

The art methods that separator is sealed on the floor for example especially has bonding problem by ca(u)lk in the cement mortar line.Because these unit often will upgrade existing hotel, thus be embedded in grease in the cement mortar hindered bonding, thereby make seepage in cleaning from the floor below this unit.Also have, ca(u)lk makes the mobile complicated of this unit.Thereby this unit is placed in below this unit, cleans the floor on the supporting leg this can increase the height of this unit, thereby reduce actively to fall from the effluent in pond and the dish-washing machine drainpipe.

Having demonstrated lower seals 149 can be sealed in this unit on the floor effectively, and particularly effective in sealing cement mortar line, because the weight of this unit is firmly held in lower seals 149 in the cement mortar line.

Fig. 8 shows an embodiment of separator 150, and it has can be used in the advantage in the embodiment in the ground.In order to illustrate, shown separator 150 has prior art heater 16 and ball-cock assembly 34, it being understood that described other improvements also can replace these parts to use here.

In Fig. 8, filter basket 60 is for carrying out coarse filtration by 12 effluents that receive that enter the mouth.Control panel 25 has sloping portion 152 and wears filter basket 60 (these improvements can be used in other structure equally) to improve fluid.Downward-sloping bottom control panel 154 has V-arrangement (or passage) with capture debris, and preferably is coated with polytetrafluoroethylene (PTFE).V-arrangement bottom control panel is transited into weir plate 156, thereby keeps a V-arrangement, and it is inclined upwardly to form hydrostatic pressure on the separating oil at valve 34 places towards desired predetermined altitude.Control panel 158 is connected with the top of shell 14, and is provided with and allows the dried up passage that therefrom flows through 160 of branch.Control panel 158 comprises enlarged 162.Heater 16 is provided with in compartment 164 and passes top board 32.Separate with compartment 164, the zone of top board 32 tops preferably can be as the oil storage tank of depositing from the oil/grease of oil/grease valve 34 166 in detachable container.Can lead to taper filter basket 60, oil storage tank 166, compartment 164 and fuel tap 34 by one or more lid (not shown) of taking away on shell 14 tops.If make chip and moisture from, then water out 168 is arranged on chip valve 170 tops.Perhaps, single outlet can be set, be used for handling water and chip.Be provided with in water out 168 fronts and be used for mesh screen 172 that chip is filtered out.

In operation, will accumulate in base plate 154 places from the chip of effluent, and will with weir plate 156 taken out bottom part at the interface to " V " shape plate 154.Current through passage 160 will upwards promote chip along passage 160.The enlarged 162 of this passage will produce eddy current and extra suction force pushing away and cross the top of weir plate 156 on the chip.Chip will fall to chip valve 170, and this valve can regularly be opened or be collected in separately in the container that is connected with chip valve 170 to the chip outlet.Remaining water flows out from water out 168 and enters drainage.

Through after a while, some chips will accumulate on the weir plate 156.Fig. 9 demonstrates a strigil, and it is equipped with mutually with the profile of weir plate 156 and removes these chips.

Preferably, all inner surfaces of separator 150 are coated with polytetrafluoroethylene (PTFE) to reduce resistance and to improve mobile.

Figure 10 shows the schematic diagram of the separator with a big oil and fat vessel, and described oil and fat vessel is used for holding from the isolated fats/oils of effluent and from the used fats/oils of operation as obtaining from Fryer.In this embodiment, ground lower separation device 150 (also can adopt the sort of ground separator shown in Fig. 1-7a-c) is connected with a storage container 170, and this storage container is enough big to preserve all abandoned oil/greases from effluent and operation.Pipeline 173 makes valve 34 be connected with storage container 170.Opening 174 makes the workman for example to pour oil/grease into storage container from oil tank.Perhaps, the oil/grease that obtains from operation directly pumping is given this container 170.The oil that heater 176 heating are adorned, thus make it can not solidify.Valve 178 (be generally fast disconnected valve) for be used for pumping from the oil/grease of container 170 so that the oil pump that reclaims provides suitable connection.Pipeline 180 is arranged between the bottom of valve 178 and container 170.

In operation, the embodiment shown in Figure 10 makes enterprise that all oil/grease is solidified so that collection company (being generally the contractor or the municipality of outside) takes away.Same design makes collection company can collect all used oil/greases from the restaurant.By using underground structure, can be from the restaurant or the back of other enterprise eliminate oil drum/dustbin.

Figure 11 shows the embodiment of two-way separator 182 (wherein lid 15 is removed) on the ground, and promptly valve 34 and heater 16 can be located on the either side of shell 14.Shell 14 comprises two fuel tap shells 72, and one of them will hold valve 34, and another will install connector thereon.Container 18 is installed by the opening on valve 34 sides 186, plate sealing of another opening 186 usefulness.Hole 186 has near their trough of belt hole so that container 18 or support member or blanket 14 to be installed.On the either side of shell 14, be provided with the part 188 that is threaded, be used for holding heater 16; Not holding the side of heater seals with thread plug.

Embodiment shown in Figure 11 makes separator 182 to install along arbitrary flow direction, and this has reduced the cost of necessary maintenance and has made it possible to installs in enterprise most effectively.In addition, if transform kitchen (commercial kitchen will be transformed in average per 5 years) again, the direction that then can change separator 182 is to adapt to the variation of flowing by pipeline.

Figure 12 shows with removing the embodiment that is mixed in the air in the split cavity 28.In some situation was for example started, the effluent with entrained air bubbles was rushed in split cavity 28 and can be caused ball 70 to be bonded in the tapered opening 82 (referring to Fig. 5 a).When entrained air bubbles was separated with effluent, they can make ball 70 keep being pressed in the tapered opening 82, and made that valve keeps closing.Have been found that the daily cleaning valve can reduce this problem, but along with the air entrainment in the split cavity 28 is overflowed by valve, it can push the oil/grease in this valve to clean to the people of this valve.

In Figure 12, breather pipe 190 is communicated with (in the illustrated embodiment, breather pipe 190 is provided with and passes untapped valve pocket 72, but it can be provided with the arbitrarily suitable part of passing top board 32) with split cavity 28.Breather pipe 190 extends near the lid 15, and hydrostatic pressure can not extrude breather pipe 190 with oil/grease like this.Perhaps, breather pipe 190 can be sent into ball valve, and any like this oil/grease of launching from breather pipe 190 will be fed to the container 18.

In operation, do not have ball valve interrupt to be communicated with owing to breather pipe and split cavity 28 directly are communicated with, so air always can leave split cavity by breather pipe 190, so this air can not make that ball valve is incorrect and closes.

Should be noted that animal tallow can solidify in breather pipe 190.Therefore, should be by electric track and heat insulation or by other method breather pipe 190 to be kept be hot.
