Description

Technical Field

[0001] The utility model relates to the technical field of epoxy resin production, in particular to a premixing device for epoxy resin processing. Background Art

[0002] Epoxy resin is a high molecular polymer, a condensation product of epichlorohydrin and bisphenol A. Due to the chemical activity of the epoxy group, it can be opened by a variety of compounds containing active hydrogen, cured and cross-linked to form a network structure, so it is a thermosetting resin. Bisphenol A epoxy resin not only has a very large output, but also has a relatively complete variety. New modified varieties are constantly increasing, and the quality is also improving.

[0003] Publication No. CN218872874U discloses an epoxy resin processing device, comprising: a box body, a feed box body, a discharge bin, a filter screen and a recovery mechanism; the bottom of the feed box body is vertically connected with a recovery mechanism and a discharge bin, and a filter screen is horizontally separated at the connection between the feed box body and the discharge bin; an anti-blocking mechanism is horizontally fixedly arranged in the inner cavity of the feed box body, and the anti-blocking mechanism comprises: a rotating shaft, a sprocket, a chain and a scraper plate; two rotating shafts are spaced and horizontally arranged in the feed box body, and the two rotating shafts are connected together by at least two parallel chain transmissions. The outer surfaces of the two chains are equidistant and are provided with scrapers whose bottoms can rest on the filter screen. The epoxy resin processing device overcomes the problem in the prior art that impurities will accumulate on the filter screen, and the impurities will not be cleaned in time, which will cause the mesh to be blocked, reducing the screening effect, requiring the machine to be stopped for manual cleaning of the filter screen, increasing the workload of the staff, and reducing the screening efficiency.

[0004] Based on the above solution to the technical problem that impurities cannot be cleaned in time, which will cause mesh clogging and reduce the screening effect, the existing epoxy resin processing needs to mix epichlorohydrin and bisphenol A. Since quantitative feeding is carried out during each processing, some materials need to wait for the next feeding. Due to the influence of external environment and humidity, some coagulate and hang on the inner wall of the box for a long time, affecting the feeding operation.

[0005] Therefore, in view of the above problems, a premixing device for epoxy resin processing is proposed. Utility Model Content

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] In order to solve the technical problem that when processing existing epoxy resins, epichlorohydrin and bisphenol A need to be mixed, and since quantitative feeding is carried out during each processing, some materials need to wait for the next feeding, and due to the influence of the external environment and humidity, some coagulated blocks are formed and adhere to the inner wall of the box, affecting the feeding operation for a long time, please refer to Figures 1 to 4 and the following technical solutions are provided:

[0023] A premixing device for epoxy resin processing, comprising a mixing tank 1. There is a bracket 2 at the upper end of the mixing tank 1. At the lower end of the bracket 2, there are two inclined rods 201 for support. There are two reserved tanks 3, and both of the two reserved tanks 3 are arranged on the bracket 2. At the lower end of the bracket 2, there are two driving boxes 303. In each of the two reserved tanks 3, there is a first stirring rod 6. In each of the two driving boxes 303, there is a first driving motor 304, and the upper end is electrically connected to the first stirring rod 6 through the reserved tank 3. On the inner sides of the two reserved tanks 3, there are guide channels 302. On both sides of the two first stirring rods 6, there are multiple equally spaced first stirring blades 601. On the inner sides of the two reserved tanks 3, there are first discharge ports 602, and they are all communicated with the guide channels 302. At the upper ends of the two reserved tanks 3, there are feeding ports 301. At the lower end of the mixing tank 1, there are three support legs 5. At the lower end of the mixing tank 1, there is a blanking tank 4. The two reserved tanks 3 can be respectively used to store the materials for processing epoxy resin, and the first stirring rod 6 arranged inside can keep the materials in a state that is not easily affected by the external environment and temperature to cause condensation into blocks or wall hanging. The first driving motors 304 in the two driving boxes 303 respectively provide driving force for the first stirring rod 6. The arranged guide channels 302 can separate the materials and enter them into the mixing tank 1, so as not to cause material confusion and achieve accurate quantitative feeding each time.

[0024] In this embodiment, as Figure 3 and 4 shown, in each of the two guide channels 302, there is a second slope 305. Inside the mixing tank 1, there is a second stirring rod 7. On both sides of the second stirring rod 7, there are multiple equally spaced second stirring blades 701, and at one end of each of the second stirring blades 701, there is a scraping plate. In both the bracket 2 and the mixing tank 1, there is a first blanking port 101, which is used to penetrate the guide channel 302 and the mixing tank 1. Inside the mixing tank 1, there is a second driving motor 702 for driving the second stirring rod 7. At the bottom inside the mixing tank 1, there is a first slope 102. Inside the first slope 102, there is a branch channel opening 103. Inside the blanking tank 4, there is a second blanking port 401, and they are all communicated with the branch channel opening 103. The second slope 305 of the internal structure of the guide channel 302 can make the materials enter the mixing tank from the reserved tank along the slope by the action of gravity. The first stirring rod 6, the second stirring blades 601 on both sides, and the scraping plate arranged on one side can prevent the materials from hanging on the wall in the reserved tank due to the height of the horizontal line. The second stirring rod 7 inside the mixing tank 1 can fully mix the two materials for the convenience of epoxy resin processing. The branch channel opening 103 arranged at the bottom of the mixing tank 1 can make the stirred materials enter the lower blanking tank 4 along the branch channel opening 103 under the action of the first slope 102 and be discharged from the equipment.

[0025] Working principle: The raw materials for processing epoxy resin are quantitatively fed into the reserve tank 3 from the feeding port 301 respectively. Before entering the mixing tank 1 from the reserve tank 3, the stirring rod 6 in the reserve tank 3 uniformly stirs the internal materials through the stirring blade 601 under the action of the driving motor 304, so that the materials enter the guide channel 302 along the discharge port 602 on the inner side of the reserve tank 3. The guide channel 302 enters the mixing tank 1 along the feeding port 101 under the action of the slope 305. The two materials are fully stirred by the stirring rod 6, the stirring blades 601 on both sides and the scraper on one side. After stirring, the materials enter the lower blanking box 4 along the branch channel port 103 under the action of the slope 102 and are discharged from the equipment.
