The degumming apparatus according to the first aspect of the present invention will be described with reference to fig. 1-10.

As shown in fig. 1 and 10, the degumming apparatus provided by the embodiment of the invention comprises a frame 100, a hydrolysis drum 200, a dewatering drum 300, a recovery drum 400 and a transfer assembly 500. Wherein:

the frame 100 is erected above the hydrolysis cylinder 200 and the dewatering cylinder 300, and the frame 100 comprises a track for sliding the transfer assembly 500 and a support beam as a foundation for erecting the track. The hydrolysis cylinder 200 is used for accommodating degumming agent containing hydrolase and carrying out enzymolysis treatment on the silk fabric; in general, in order to adapt the working temperature of the enzymolysis, the hydrolysis cylinder 200 is further provided with a heating device, and the heating device can ensure that the temperature in the hydrolysis cylinder 200 is within the optimal activity temperature range of the hydrolase. After the silk fabric is degummed through the enzymolysis in the hydrolysis tube 200, the silk fabric is transferred to the dewatering tube 300 by the transfer component 500, the dewatering tube 300 carries out centrifugal dewatering on the silk fabric, and the degumming agent containing hydrolase, which is remained on the silk fabric, is removed. The recovery cylinder 400 is communicated with the hydrolysis cylinder 200 and the dewatering cylinder 300, the hydrolysis cylinder 200 contains hydrolytic enzyme degumming agent which flows into the recovery cylinder 400 after a certain time or a certain amount of silk fabric is processed, and the silk fabric in the dewatering cylinder 300 is dehydrated for a certain time or the separated solvent flows into the recovery cylinder 400 after a certain water content.

According to the degumming equipment in the embodiment of the invention, the hydrolytic enzyme-containing degumming agent after being hydrolyzed and separated by centrifugal dehydration is recycled, so that the environmental pollution caused by direct discharge of the hydrolytic enzyme-containing degumming agent is avoided, and the recycled hydrolytic enzyme-containing degumming agent can be recycled through secondary treatment, so that the economic benefit is improved.

In one embodiment, as shown in figures 1, 2 and 9, in order to further improve the dewatering effect on silk fabric in the dewatering cylinder 300, an adjusting assembly is also arranged in the dewatering cylinder 300. In general, the silk fabric is wound around the winding roller 510, the winding roller 510 is placed in the dewatering cylinder 300, the winding roller 510 is driven to rotate by a rotating mechanism in the dewatering cylinder 300, and the degumming agent remaining in the silk fabric is removed by centrifugal force during rotation.

The applicant has found that for centrifugal dewatering of the dewatering cylinder 300, the closer to the silk fabric at the axis of rotation the poorer the dewatering effect and the further away from the silk fabric at the axis of rotation the better the dewatering effect. Therefore, an adjusting component is arranged, and the positions of the silk fabrics on the silk winding rollers 510 relative to the rotation axis are changed through the adjusting component, so that the centrifugal dewatering effect of the silk fabrics on the silk winding rollers 510 is changed, the dewatering effect of the silk fabrics on the silk winding rollers is uniform as far as possible, and the requirements are met. The applicant has also found that, in the initial stage of the centrifugal dewatering, due to the high amount of degumming-containing agent in the silk fabric, for example 5% by mass, even if the winding roller 510 is located relatively close to the axis of rotation, it is possible to remove the degumming agent by centrifugation effectively, for example to reduce the amount of degumming-containing agent to 2% by mass; at the later stage of dewatering, because the amount of degumming-containing agent in the silk fabric is small, for example 2% by mass, the degumming agent is difficult to be centrifuged out if the winding roller 510 is still relatively close to the rotation axis, and the degumming agent can be continuously centrifuged out if the winding roller 510 is relatively far from the rotation axis, for example, the degumming-containing agent is reduced to 1% by mass.

From this, set up the control basis of adjusting part into the quality size of twining the silk fabric, at the initial stage of dehydration, adjusting part does not act on or acts on lessly, and because the dosage that contains in the silk fabric is more this moment, need not to carry out position control and can enough carry out preliminary dehydration. At the dehydration later stage, the degumming agent in the silk fabric has already been centrifuged and has been taken off and remove a part this moment, and the whole quality of silk fabric reduces, and the adjusting part effect this moment is adjusted the position of twining roller 510, if will be located originally and move to keeping away from axis of rotation department to twining roller 510 that is close to axis of rotation department, or carry out periodic motion to many twining rollers 510, make single twining roller 510 periodically be located and be close to axis of rotation department and keep away from axis of rotation department to this improves holistic dehydration effect.

Further, the adjustment assembly includes a drive cylinder, the transfer assembly 500 includes a transfer frame 520, and the plurality of winding rollers 510 are slidably disposed on the transfer frame 520. The driving signal of the driving cylinder is the total mass of the transfer assembly 500, and since only the mass of the degumming agent in the total mass of the transfer assembly 500 is changed during the dehydration process, the driving signal of the driving cylinder can also be considered as the mass of the degumming agent. The driving signal can be obtained by an electrical signal sensor, for example, a mass sensor is arranged between the transferring assembly 500 and the installation base thereof, the mass of the transferring assembly 500 is detected in real time, and the signal is transmitted to a driving cylinder, and the driving cylinder is actuated to drive the winding roller 510 to slide relative to the transferring frame 520, and the relative positions of the winding roller 510 and the rotating axis are changed due to the relative fixed positions of the transferring frame 520 and the rotating axis.

The drive signal for the drive cylinder may also be derived from mechanical structures. For example, a return spring is arranged between the transfer assembly 500 and the installation base thereof, and after the mass of the transfer assembly 500 is changed, the relative position relationship between the transfer assembly 500 and the installation base is changed under the action of the return spring. The cylinder body and the piston rod of the driving cylinder are respectively connected to the transferring assembly 500 and the mounting base, and after the transferring assembly 500 and the mounting base move relatively, the piston rod is driven to move, so that the volume of the cavity of the driving cylinder is changed. In general, when the mechanical structure controls the action of the driving cylinder, an execution cylinder is further provided, the execution cylinder is communicated with the driving cylinder, the action of the driving cylinder drives the action of the execution cylinder, and after the action of the execution cylinder, the winding roller 510 is driven to slide relative to the transfer frame 520.
