Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
Figure 1 shows that the structural representation of gelatin extraction device among the utility model embodiment.As shown in Figure 1, the gelatin extraction device among the utility model embodiment comprises tank body 6, be arranged on the opening for feed 19 on tank body 6 sidewalls and be arranged on the slag notch 15 of tank body 6 bottoms, and opening for feed 19 and slag notch 15 places are provided with respectively feed valve 1 and the valve 9 of slagging tap.Gelatin extraction device in the present embodiment also comprises discharge gate 19, discharge port 16 and feedback outlet 14, discharge port 16 is arranged on the bottom of tank body 6, feedback outlet 14 is arranged on the top of tank body 6, and discharge gate 19 is connected with feedback outlet and is connected by pump 12 with discharge port 16 respectively, and at discharge gate 19, discharge port 16 and feedback outlet 14 places blow-off valve 10, bleeder valve 7 and material returning valve 4 is set respectively.Wherein, the sidewall of tank body 6 bottom also is provided with for the liquid header 8 that filters the glue slag, and liquid header 8 is communicated with slag notch 15.
Preferred tank body 6 has the cone bottom structure in the present embodiment, is convenient to the discharge of glue and glue slag.In order further to improve the concentration of glue, liquid header 8 can be the taper filtering net, and can be fixedly connected with by the mode of welding with the cone downside wall of tank body 6 at the bottom of the cone of this taper filtering net, and the vertex of a cone of this taper filtering net is communicated with slag notch 15.In the actual application, the can body volume of tank body 6 is much larger than the cone volume at the end, and the glue that boils during discharging forms laminar flow in can body, improved the concentration of discharging glue.Wherein, the net of taper filtering net footpath can be 2~5mm.
After glue boils and finishes, in order thoroughly to clear up the glue slag on the taper filtering net, be airtight removably connecting with tank body 6 at the bottom of the cone of preferred tank body 6 in the present embodiment, connect such as bolt, and in the junction sealing-ring is set.
The gelatin extraction device prepares the detailed process of gelatin and is in the present embodiment:
At first, close slag tap valve 9 and blow-off valve 10, open feed valve 1, will put into tank body 6 by the slip that skeletal grain or skin raw material and water form by a certain percentage from opening for feed 19, automatic conveying device control can be set in the present embodiment open feed valve 1 and in tank body 6, add slip;
Then, under certain temperature condition, the slip in the tank body 6 is boiled, generate glue.Can open at the very start pump 12, also can open over time pump 12, open simultaneously bleeder valve 7 and material returning valve 4, pump glue by pump 12 and be back to the tank body 6 from feedback outlet 14;
At last, after the concentration of glue is qualified, close material returning valve 4, open blow-off valve 10, pump glue by pump 12 and discharge from discharge gate 19, carry out subsequent technique;
After glue boils and finishes, open the glue slag that the valve 9 of slagging tap is discharged in the tank body 6.
Gelatin extraction device provided by the utility model arranges feedback outlet by the top at tank body, and be provided for filtering the liquid header of glue slag in the sidewall of tank body bottom, and liquid header is communicated with slag notch, realized the glue that discharge port flows out is back in the tank body, prevent that the heterogeneity phenomenon from appearring in the glue that extracts, when the concentration of glue is qualified, just glue is discharged from discharge gate, improved the efficient that boils of the quality of glue and glue.
Wherein, when glue is back in the tank body 6, need glue evenly to flow downward, prevent from affecting glue in the tank body 6 continue boil.It is a variety of to realize that mode that uniform liquid flows has, and can be below feedback outlet 14 in the present embodiment be provided for liquid distributor 3 that uniform liquid is flowed downward perpendicular to the liquid inflow direction, and liquid distributor 3 can be sieve plate or screen casing.
Boiling under the certain temperature condition of glue carried out, in order to make the temperature in the tank body 6 reach this temperature, can establish the chuck 5 that mates with tank body 6 sidewall shape at the sidewall external surface peripheral ring of tank body 6 in the present embodiment, wherein, the upper and lower edge of chuck 5 is connected with the sidewall of tank body 6 is airtight that (airtight connection can utilize prior art to realize, do not repeat them here), sidewall at chuck 5 arranges water-in 17 and water outlet 18, and at water-in 17 and water outlet 18 places water intaking valve 13 and outlet valve 11 is set respectively.Can open water intaking valve 13, pass into hot water from water-in 17 to chuck 5 or steam heats tank body 6.
In order to realize that constant temperature carries glue, shorten the glue time of carrying, preferred water intaking valve 13 and outlet valve 11 are magnetic valve, and set temperature control device 21, temperature-control device 21 can comprise temperature sensor, the temperature in the Real-time Measuring measuring tank body 6, and control water intaking valve 13 and outlet valve 11 by PID.When the temperature in the tank body 6 was lower than glue and boils required temperature, temperature-control device 21 control water intaking valves 13 and outlet valve 11 were opened, and change hot water or water vapour in the chuck 5, realize the constant temperature of tank body 6.
Too high in order to prevent the return current glue hydraulic coupling that pump 12 pumps to the tank body 6, cause the damage of equipment, in the present embodiment pressure monitoring device 22 can also be set in the exit of pump 12, be used for to measure and show pump 12 close valve pressure (namely closing the valve lift), when closing the valve hypertonia, what the frequency that can regulate pump 12 reduced pump 12 closes valve pressure.
Also be provided with manhole 2 in the present embodiment on the sidewall of tank body 6, make things convenient for the people to pass in and out tank body 6, be convenient to maintenance and the maintenance of equipment.
The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and replacement, these improvement and replacement also should be considered as protection domain of the present utility model.
