[0034] The following is combined with Figure 1-4 This application is described in further detail.

[0035] The embodiment of the present application discloses a waste rubber collection mechanism.

[0036] Embodiment 1:

[0037] Reference Figure 1 The waste rubber collection mechanism includes a collection tank 1, an oil outlet pipe 2, a circulation pipe 3 and a recovery barrel 4. The collection tank 1 is arranged in the furnace of the degumming sintering furnace to collect the waste rubber condensed near the furnace mouth. The oil outlet pipe 2 and the circulation pipe 3 are both round pipes. The upper end of the oil outlet pipe 2 extends into the furnace and is connected to the collection tank 1. The upper end of the circulation pipe 3 is connected to the lower end of the oil outlet pipe 2, and the circulation pipe 3 is connected to the oil outlet pipe 2. The lower end of the circulation pipe 3 extends into the recovery barrel 4 placed on the ground, so that the circulation pipe 3 is connected to the recovery barrel 4.

[0038] In actual application, the waste rubber formed by condensation of the gaseous adhesive volatilized from the product in the furnace flows to the collecting tank 1 for collection, and under the action of gravity, the waste rubber flows into the oil outlet pipe 2 and flows into the recovery barrel 4 through the circulation pipe 3 for recovery, which can effectively prevent the waste rubber from flowing back into the furnace, thereby minimizing the gasification of the waste rubber again, thereby reducing the operating load of the waste gas treatment device at the rear end of the degumming sintering furnace, thereby improving the economic benefits of the enterprise.

[0039] In some embodiments, the waste rubber collection mechanism further includes a switch valve 5, one end of which is fixedly connected to the oil outlet pipe 2, and the other end of which is fixedly connected to the circulation pipe 3, so as to realize the connection between the oil outlet pipe 2 and the circulation pipe 3, so as to control the connection between the oil outlet pipe 2 and the circulation pipe 3, thereby controlling the recycling of the waste rubber. At the same time, the flow between the oil outlet pipe 2 and the circulation pipe 3 can also be controlled to ensure that the recycling barrel 4 can stably recycle the waste oil.

[0040] The implementation principle of this embodiment is: in actual application, the waste rubber formed by condensation of the gas adhesive volatilized from the product in the furnace flows to the collection tank 1 for collection, and under the action of gravity, the waste rubber flows into the oil outlet pipe 2 and flows into the recovery barrel 4 through the circulation pipe 3 for recovery, which can effectively prevent the waste rubber from flowing back into the furnace, thereby minimizing the gasification of the waste rubber again, thereby reducing the operating load of the waste gas treatment device at the rear end of the degumming sintering furnace, thereby improving the economic benefits of the enterprise.

[0041] Embodiment 2:

[0042] Reference Figure 2 and Figure 3 The difference between this embodiment and embodiment 1 is that the waste rubber collection mechanism also includes a guide head 6, and the lower end of the guide head 6 is sleeved on the barrel mouth of the recycling barrel 4. At this time, the lower end of the flow tube 3 extends into the guide head 6, and the flow tube 3 is located above the recycling barrel 4, that is, there is a certain distance between the lower end of the flow tube 3 and the barrel mouth of the recycling barrel 4. When the recycling barrel 4 needs to be replaced, the guide head 6 can be pulled upward to move the recycling barrel 4, and the circulation tube 3 is avoided as much as possible to limit the horizontal movement of the recycling barrel 4, so as to facilitate the replacement of the recycling barrel 4 placed on the ground.

[0043] In some embodiments, the flow guide head 6 includes a first flow guide pipe 61 and a second flow guide pipe 62, the first flow guide pipe 61 is located below the second flow guide pipe 62 and is sleeved on the barrel mouth of the recovery barrel 4, the second flow guide pipe 62 is threadedly connected to the inner side of the first flow guide pipe 61, and the overall length of the flow guide head 6 is adjusted by rotating the second flow guide pipe 62, so as to be suitable for recovery barrels 4 of different heights. In addition, since the second flow guide pipe 62 is threadedly connected to the inner side of the first flow guide pipe 61, it can effectively ensure that the waste oil in the second flow guide pipe 62 flows fully and stably into the first flow guide pipe 61, so as to improve the recovery efficiency of the waste oil.

[0044] Reference Figure 4 In some embodiments, a groove 611 is provided at the lower end of the first guide tube 61 along its circumference, so that the mouth of the recovery barrel 4 is embedded in the groove 611. At the same time, the inner diameter of the guide head 6 is the same as the inner diameter of the mouth of the recovery barrel 4, so that the waste rubber can flow more smoothly from the first guide tube 61 into the recovery barrel 4, further improving the recovery efficiency of the waste oil.

[0045] In some embodiments, the guide head 6 also includes a locking sleeve 63, and the lower end of the first guide tube 61 is provided with a plurality of deformation grooves 612 along its length direction. The plurality of deformation grooves 612 are evenly spaced along the circumference of the first guide tube 61 and are connected to the embedded groove 611. When the first guide tube 61 is sleeved on the barrel mouth of the recovery barrel 4, the lower end of the first guide tube 61 is elastically deformed outward under the action of the deformation groove 612, and the locking sleeve 63 is threadedly connected to the outer side of the lower end of the first guide tube 61. The locking sleeve 63 is rotated to limit the lower end of the first guide tube 61, thereby improving the stability of the first guide tube 61 sleeved on the barrel mouth of the recovery barrel 4, and also facilitating the first guide tube 61 to be sleeved on the barrel mouth of the recovery barrel 4.

[0046] In some embodiments, the guide head 6 also includes a seal 64, which is disposed between the first guide tube 61 and the barrel mouth of the recovery barrel 4, that is, the seal 64 is located in the embedding groove 611 and the upper and lower sides are respectively abutted against the first guide tube 61 and the barrel mouth of the recovery barrel 4 to improve the sealing between the first guide tube 61 and the barrel mouth of the recovery barrel 4 to minimize the leakage of waste rubber.

[0047] The implementation principle of this embodiment is: by setting the guide head 6, it is convenient to replace the recovery barrel 4 placed on the ground, and when the first guide tube 61 is sleeved on the barrel mouth of the recovery barrel 4, the lower end of the first guide tube 61 is elastically deformed outward under the action of the deformation groove 612, and the locking sleeve 63 is threadedly connected to the outer side of the lower end of the first guide tube 61, and the locking sleeve 63 is rotated to limit the lower end of the first guide tube 61, thereby improving the stability of the first guide tube 61 sleeved on the barrel mouth of the recovery barrel 4, and also facilitating the first guide tube 61 to be sleeved on the barrel mouth of the recovery barrel 4.
