[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1-Figure 3 The utility model provides an embodiment: a reactor for reducing residual furan resin tailings, comprising a shell 1, a feed port 2 is fixedly connected to the top of the outer wall of the shell 1, a discharge port 3 is fixedly connected to the bottom of the outer wall of the shell 1, and connecting flanges are provided on the surfaces of the feed port 2 and the discharge port 3, so that they can be conveniently connected and fixed with an external device, and a valve body handle is provided on the surface of the discharge port 3, which is the prior art.

[0033] Reference Figure 2-Figure 4 The inner wall of the shell 1 is provided with a stirring assembly 4, which includes a motor 41, which is fixedly connected to the top of the outer wall of the shell 1, and a rotating sleeve 42 is rotatably connected to the top of the inner wall of the shell 1. The output shaft of the motor 41 is fixedly connected to the rotating sleeve 42. The rotating sleeve 42 is rotated at a high speed by the rotation of the motor 41, so that the internal furan resin is fully dispersed through multiple groups of stirring rods 44. The top of the inner wall of the rotating sleeve 42 is elastically connected to the rotating rod 43 through a limit spring 47. One end of the limit spring 47 is fixedly connected to the top of the inner wall of the rotating sleeve 42, and the other end of the limit spring 47 is fixedly connected to the top of the outer wall of the rotating rod 43. The function of the limit spring 47 is that when the rotation of the stirring rod 44 contacts the contact block 46, the rotating rod 43 will be driven to move upward on the inner wall of the rotating sleeve 42, and the limit spring 47 will be elastically compressed until the contact is cancelled, and it will be automatically reset by the elastic action of the limit spring 47.

[0034] Reference Figure 2-Figure 3The top of the outer wall of the rotating rod 43 is slidably connected to the inner wall of the bottom end of the rotating sleeve 42. The inner wall of the rotating sleeve 42 is provided with a sliding groove that fits the top of the rotating rod 43, so that the rotating rod 43 can only move up and down on the inner wall of the rotating sleeve 42 and cannot be separated from its inner wall. When the rotating sleeve 42 rotates, it will drive the rotating rod 43 to rotate synchronously. The bottom end of the outer wall of the bottom scraper 45 contacts the bottom end of the inner wall of the shell 1. The contact between the two can scrape off the furan resin adsorbed on the bottom end of the inner wall of the shell 1 through the bottom scraper 45, and the bottom A cavity is opened on the surface of the scraper 45, and the raw materials can be broken up during the scraping process. A plurality of stirring rods 44 are fixedly connected to the surface of the rotating rod 43. The bottom end of the outer wall of the stirring rod 44 contacts the surface of the contact block 46. The two are in contact, so that the stirring rod 44 is squeezed by the contact block 46 to drive the rotating rod 43 to move up and down. The inner side wall of the shell 1 is fixedly connected to the contact block 46, and the outer wall of the bottom end of the rotating rod 43 is fixedly connected to two groups of bottom scrapers 45. The surface of the rotating rod 43 is provided with a scraping assembly 5.

[0035] Reference Figure 2-Figure 3 The scraping assembly 5 includes a fixed rod 51, the inner wall of the fixed rod 51 is elastically connected to a sliding rod 53 by a return spring 52, one end of the return spring 52 is fixedly connected to the inner wall of the fixed rod 51, and the other end of the return spring 52 is fixedly connected to the left outer wall of the sliding rod 53. The function of the return spring 52 is that when the side scraper 55 contacts with a hard object, it can squeeze the sliding rod 53 to move on the inner wall of the fixed rod 51, and exert a buffering and resetting effect through the squeezing of the return spring 52. The sliding rod 53 is slidably connected to the inner wall of the return spring 52, and the right outer wall of the side scraper 55 contacts the inner side wall of the shell 1. The contact between the two can better scrape the furan resin attached to the inner wall of the shell 1 through the side scraper 55 to avoid the tailing material being adsorbed on the inner wall, which is troublesome and inconvenient during subsequent cleaning. The outer wall of the sliding rod 53 is fixedly connected to a connecting plate 54, and a plurality of side scrapers 55 are fixedly connected to the right surface of the connecting plate 54.

[0036] Working principle: When the furan resin is processed and reacted, the material is introduced into the shell 1 through the feeding port 2. At this time, the motor 41 can be started to allow its output shaft to drive the rotating sleeve 42 to rotate, and drive the rotating rod 43 on the inner wall of the rotating sleeve 42 to rotate synchronously with it. The multiple groups of stirring rods 44 will fully stir the furan resin raw material. At the same time, during the rotation of the uppermost stirring rod 44, the top of its outer wall will contact the outer wall of the contact block 46, thereby squeezing the stirring rod 44 to drive the rotating rod 43 to move upward on the inner wall of the rotating sleeve 42, and allowing the limit spring 47 to be elastically compressed until the stirring rod 44 is no longer in contact with the contact block 46. The rotating rod 43 will be elastically acted upon by the limit spring 47 to restore the multiple groups of stirring rods 44 to their initial positions, thereby achieving the effect of up and down stirring, so that the reaction effect on the furan resin raw material is better.

[0037] At the same time, when the rotating rod 43 rotates, the two groups of bottom scrapers 45 at its bottom will contact the bottom end of the shell 1, thereby breaking up the raw materials adsorbed on its surface and breaking up the materials through the empty grooves on its surface. At the same time, the rotating rod 43 will also drive the fixed rod 51 to rotate, so that the side scraper 55 can move up and down during the rotation, thereby cleaning the inner wall of the shell 1 to prevent the raw materials from being adsorbed on its inner wall, which is troublesome and inconvenient during subsequent cleaning, and also avoids the tailings from being adsorbed on the inner wall of the shell 1 after the material reacts.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
