The sieve is detachable construction in this embodiment, can regularly dismantle this sieve and wash to avoid the material to block up the filtration pore on the sieve and cause the problem that vacuum pump 70 can not effectively work.

The resin separation box 20 in this embodiment is provided with a high temperature resistant conveyor belt, and the material moves forward in a specified time period, and when the operation is finished, the resin is completely separated. Reference may be made in particular to the pyrolysis chamber of the continuous operation type pyrolysis recovery device for plastic products disclosed in the chinese utility model patent with the publication number CN205112155U and the pyrolysis device of the decomposition recovery system and method for glass fiber reinforced plastics with gas purification function disclosed in the chinese utility model patent with the publication number CN 104646400B. The applicant does not give further details about the specific structure and operation of the resin separation tank 20.

In the embodiment of the present invention, the conveyor 30 is a screw conveyor, and the screw conveyor utilizes a motor to drive a screw shaft to rotate, and pushes the material to achieve the conveying purpose. When the screw shaft rotates, the material is pushed by the blades to move forwards along the bottom of the conveyor 30 due to the gravity of the material and the friction force generated between the material and the wall of the groove body, so that the purpose of conveying the material is achieved. The conveyor 30 can convey horizontally, obliquely or vertically, and the conveyor 30 has the advantages of simple structure, small cross-sectional area, good sealing property, convenience in operation, easiness in maintenance, convenience in closed transportation and the like.

As shown in fig. 1, the conveyor 30 is connected to the extension pipe 40 through a frustum-shaped reducer 90, a large diameter end of the frustum-shaped reducer 90 is connected to the outlet of the conveyor, and a small diameter end of the frustum-shaped reducer 90 is connected to the inlet of the pipe body.

The frustum-shaped reducing joint 90 is arranged, so that the conveyor 30 and the lengthened pipe 40 can be conveniently detached and replaced, meanwhile, the reducing between the conveyor 30 and the lengthened pipe 40 is smoother, and materials in the conveyor 30 enter the lengthened pipe 40 through the frustum-shaped reducing joint 90 and are extruded, so that the self-sealing effect is achieved.

It should be noted that, in the present embodiment, the fiber product needs to be manually added during the initial operation, so that the fiber product is conveyed to the extension pipe 40 through the conveyor 30 to perform the initial sealing function.

The ratio of the diameter of the small diameter end of the frustum-shaped reducer union 90 to the diameter of the large diameter end of the frustum-shaped reducer union 90 is in the range of 0.3 to 0.8. The value range can be selected according to the solid discharged from the outlet, and the degree of tightness of the extruded material in the elongated tube 40 is related to the conveying speed of the conveyor 30, and the higher the conveying speed of the conveyor 30 is, the more tight the extruded material in the elongated tube 40 is, and otherwise, the more loose the extruded material in the elongated tube 40 is.

Use the embodiment of the utility model provides a during operation carries the material to feeding box 10 in through outside promotion conveyer belt 50, and most air has all been pushed away by the material this moment, but still can remain a small amount of air. At this time, the oxygen probe 80 starts to work, the oxygen content in the material is detected, and when the oxygen content exceeds a set value, the vacuum pump 70 starts to vacuumize the interior of the feeding box 10.

The vacuumized materials enter the resin separation box 20 and move forward under the action of the high-temperature-resistant conveying belt, and when the operation is finished, the resin is completely separated. The separated material enters the conveyor 30 and moves forward along the bottom of the conveyor 30 to the outlet of the conveyor by the conveying action of the conveyor 30. During the material after the separation entered into extension pipe 40 through frustum form reducer union 90, the material after the separation received the extrusion and formed the shutoff layer through the reducing effect, and this shutoff layer can completely cut off inside the outside air admission device of extension pipe 40 to play the self sealss function of this embodiment.

The extruded material slowly moves forward in the lengthening pipe 40 and is conveyed to downstream equipment from the outlet of the pipe body to complete the recovery and treatment work of the glass fiber reinforced plastic solid waste.

Preferably, the embodiment of the present invention further provides a solid waste continuous feeding treatment device, which comprises a feeding box 10, a separation box, a conveyor 30 and an extension pipe 40. The feeding box 10 is a box structure with openings at both upper and lower ends. The separator box sets up in the below of feeding case 10, and the separator box includes material entry and material export, and material entry is located the upper portion of separator box left end, and the material export is located the lower part of separator box right-hand member, and the material entry communicates with the export of feeding case 10. The conveyor 30 has a conveyor inlet and a conveyor outlet, with the conveyor inlet communicating with the material outlet. The extension pipe 40 is a straight pipe structure with openings at two ends, the extension pipe 40 is provided with a pipe inlet and a pipe outlet, the pipe inlet is connected with the outlet of the conveyor, the pipe outlet is connected with downstream equipment, and the diameter of the pipe inlet is smaller than that of the outlet of the conveyor.

Wherein the above materials comprise resin solid wastes (such as waste wind power blades, button wastes, shoemaking and luggage wastes, etc.).
