Description

Technical Field

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

[0002] Waterborne epoxy resin can be divided into anionic resin and cationic resin. During the production of waterborne epoxy resin, it needs to be mixed and stirred. The existing waterborne epoxy resin production and mixing devices on the market do not have the function of facilitating discharging. During the production and use process, it is easy to have the phenomenon that the bottom material accumulates and is difficult to discharge, which affects the processing and use of the next batch, and is not conducive to the operation and use of users. A solution to the above technical problems needs to be proposed;

[0003] For example, in the prior art with the publication number CN212680760U, the device in this solution can make the discharging operation of users more convenient and facilitate the discharging and collection of users through the use of a liquid outlet pipe and a control valve; the use of a sealing cover can effectively avoid the phenomenon that liquid splashes during the stirring process in the inner cavity of the device and affects the working environment, and ensures the cleanliness of the working environment; the use of a fixing frame can effectively avoid the phenomenon that the driving motor shakes during use and affects the use, and improves the stability of the driving motor during use;

[0004] During the production and processing of waterborne epoxy resin, a curing agent needs to be added for reaction. Some curing agents react relatively quickly with waterborne epoxy resin. Pouring them in one go may cause the reaction to be too fast to control, and may even cause uneven local curing or over-curing. Content of the Utility Model

[0005] The technical problems solved by this solution are as follows:

[0006] (1) How to solve the problems that some curing agents react relatively quickly with waterborne epoxy resin, are difficult to control, and may even cause uneven local curing or over-curing.

[0007] The purpose of the utility model can be achieved by the following technical solutions: A mixing device for waterborne epoxy resin production and processing includes a housing and a driving motor fixedly installed on its top. A working cavity is opened inside the housing. A rotating shaft is vertically arranged in the middle of the working cavity. The top end of the rotating shaft movably penetrates the housing and is fixedly connected to the output end of the driving motor. A plurality of stirring blades are fixedly installed on the outer wall of the middle part of the rotating shaft. A feeding mechanism for uniformly spraying the curing agent is arranged at the top of the working cavity;

[0008] The feeding mechanism includes an L-shaped pipe. A first connecting pipe and a second connecting pipe are fixedly communicated with the middle part of the L-shaped pipe. The positions of the first connecting pipe and the second connecting pipe correspond to each other. A transmission rod is arranged in the second connecting pipe. A roller is rotatably arranged at the bottom end of the transmission rod. A guide frame for guiding the transmission rod is fixedly installed at the bottom of the inner wall of the second connecting pipe.

[0009] A further technical improvement of the present utility model is that: a first piston for blocking the L-shaped pipe is fixedly installed at the top end of the transmission rod, and a second piston is fixedly installed in the middle of the transmission rod. A tension spring is fixedly connected between the bottom of the second piston and the guide frame.

[0010] A further technical improvement of the present utility model is that: the output end of the L-shaped pipe faces the rotating shaft. A circular plate is fixedly sleeved on the outer wall of the middle part of the rotating shaft. The circular plate is located below the L-shaped pipe, and an inclined block is fixedly installed on the outer edge surface of the circular plate; several stirring blades are driven to rotate by the rotating shaft. At this time, the circular plate drives the inclined block to rotate around the rotating shaft. During this process, an intermittent upward driving force is provided to the roller through the inclined block, so that the transmission rod drives the first piston and the second piston to slide upward. The first piston is intermittently staggered from the middle part of the L-shaped pipe. At the same time, the second piston prevents the curing agent from leaking, facilitating the curing agent in the liquid storage tank to flow out from the output end of the L-shaped pipe, and then flowing along the rotating shaft to the circular plate. Since the circular plate rotates, the curing agent on its top is evenly splashed from the edge of the circular plate to the water-based epoxy resin due to the influence of centrifugal force, and several stirring blades are used to evenly stir the water-based epoxy resin. At the same time, since the curing agent flows out intermittently from the output end of the L-shaped pipe, the flowing speed of the curing agent is slower, avoiding the rapid reaction between the curing agent and the water-based epoxy resin, and causing uneven local curing or over-curing.

[0011] A further technical improvement of the present utility model is that: the inclined surface of the inclined block is inclined upward, and the position of the inclined block corresponds to the position of the roller.

[0012] A further technical improvement of the present utility model is that: a liquid storage tank for storing the curing agent is fixedly installed at the top of the outer shell. The input end of the L-shaped pipe penetrates through the outer shell and is communicated with the bottom of the liquid storage tank.

[0013] A further technical improvement of the present utility model is that: a feed pipe is communicated with the side surface of the outer shell, and a discharge pipe is fixedly communicated with the bottom of the outer shell. A control valve is fixedly installed in the middle of the discharge pipe.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] When the utility model is in use, a plurality of stirring blades are driven to rotate by the rotating shaft. At this time, the circular plate drives the inclined block to rotate around the rotating shaft. In this process, the inclined block provides an intermittent upward driving force to the roller, so that the transmission rod drives the first piston and the second piston to slide upward, and the first piston is intermittently staggered with the middle part of the L-shaped tube. At the same time, the second piston prevents the leakage of the curing agent, so that the curing agent in the liquid storage tank flows out from the output end of the L-shaped tube, and then flows to the circular plate along the rotating shaft. As the circular plate rotates, the curing agent on the top thereof is evenly splashed from the edge of the circular plate to the water-based epoxy resin due to the influence of centrifugal force, and the water-based epoxy resin is evenly stirred in cooperation with the plurality of stirring blades. At the same time, as the curing agent intermittently flows out from the output end of the L-shaped tube, the curing agent flows out at a slower speed, so as to avoid the curing agent and the water-based epoxy resin reacting rapidly, causing uneven local curing or over-curing.

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0023] See also Figures 1-4As shown in the figure, a mixing device for the production and processing of water-based epoxy resin includes a housing 3 and a driving motor 8 fixedly installed on its top. A working chamber is provided inside the housing 3. A rotating shaft 4 is vertically arranged in the middle of the working chamber. The top end of the rotating shaft 4 movably penetrates the housing 3 and is fixedly connected to the output end of the driving motor 8. A plurality of stirring blades are fixedly installed on the outer wall of the middle part of the rotating shaft 4. A feeding mechanism 2 for uniformly spraying the curing agent is arranged at the top of the working chamber.

[0024] Please refer to Figures 1-4 As shown in the figure, the above-mentioned feeding mechanism 2 includes an L-shaped pipe 201. A first connecting pipe 204 and a second connecting pipe 209 are fixedly communicated in the middle of the L-shaped pipe 201. The positions of the first connecting pipe 204 and the second connecting pipe 209 correspond to each other. A transmission rod 206 is arranged inside the second connecting pipe 209. A roller 202 is rotatably arranged at the bottom end of the transmission rod 206. A guide frame 208 for guiding the transmission rod 206 is fixedly installed at the bottom of the inner wall of the second connecting pipe 209.

[0025] Please refer to Figures 1-4 As shown in the figure, a first piston 205 for blocking the L-shaped pipe 201 is fixedly installed at the top end of the above-mentioned transmission rod 206, and a second piston 207 is fixedly installed in the middle of the transmission rod 206. A tension spring is fixedly connected between the bottom of the second piston 207 and the guide frame 208.

[0026] Please refer to Figures 1-4 As shown in the figure, the output end of the above-mentioned L-shaped pipe 201 is arranged towards the rotating shaft 4. A circular plate 203 is fixedly sleeved on the outer wall of the middle part of the rotating shaft 4. The circular plate 203 is located below the L-shaped pipe 201, and an inclined block 210 is fixedly installed on the outer edge surface of the circular plate 203; by driving the plurality of stirring blades to rotate through the rotating shaft 4, at this time, the circular plate 203 drives the inclined block 210 to rotate around the rotating shaft 4. During this process, an intermittent upward driving force is provided to the roller 202 through the inclined block 210, so that the transmission rod 206 drives the first piston 205 and the second piston 207 to slide upward. The first piston 205 is intermittently staggered from the middle of the L-shaped pipe 201. At the same time, the second piston 207 prevents the curing agent from leaking, facilitating the curing agent in the liquid storage tank 1 to flow out from the output end of the L-shaped pipe 201, and then flowing along the rotating shaft 4 to the circular plate 203. Since the circular plate 203 rotates, the curing agent on its top is uniformly splashed from the edge of the circular plate 203 onto the water-based epoxy resin due to the influence of centrifugal force, and the water-based epoxy resin is uniformly stirred in cooperation with the plurality of stirring blades. At the same time, since the curing agent flows out intermittently from the output end of the L-shaped pipe 201, the flowing speed of the curing agent is slower, avoiding the rapid reaction between the curing agent and the water-based epoxy resin, which may cause uneven local curing or over-curing.

[0027] Please refer to Figure 2 and Figure 4As shown, the inclined surface of the above-mentioned inclined block 210 is inclined upward, and the position of the inclined block 210 corresponds to the position of the roller 202.

[0028] Please refer to Figures 1-3 As shown, a liquid storage tank 1 for storing curing agent is fixedly installed at the top of the above-mentioned outer shell 3, and the input end of the L-shaped pipe 201 penetrates through the outer shell 3 and is communicated with the bottom of the liquid storage tank 1.

[0029] Please refer to Figure 1 As shown, a feed pipe 7 is communicated with the side of the above-mentioned outer shell 3, and a discharge pipe 6 is fixedly communicated with the bottom of the outer shell 3. A control valve is fixedly installed in the middle of the discharge pipe 6.

[0030] Please refer to Figure 1 As shown, a guiding frame 5 for limiting the bottom of the rotating shaft 4 is fixedly installed on the inner wall of the above-mentioned outer shell 3.

[0031] Working principle: When the present utility model is in use, first, water-based epoxy resin is put into the outer shell 3 through the feed pipe 7, and the driving motor 8 is started, so that the rotating shaft 4 drives several stirring blades to rotate. At this time, the circular plate 203 drives the inclined block 210 to rotate around the rotating shaft 4. During this process, an intermittent upward driving force is provided to the roller 202 through the inclined block 210, so that the transmission rod 206 drives the first piston 205 and the second piston 207 to slide upward. The first piston 205 is intermittently staggered from the middle of the L-shaped pipe 201, and at the same time, the second piston 207 is used to prevent the leakage of the curing agent, so that the curing agent in the liquid storage tank 1 flows out from the output end of the L-shaped pipe 201, and then flows along the rotating shaft 4 to the circular plate 203. Since the circular plate 203 rotates, the curing agent on its top is uniformly splashed onto the water-based epoxy resin due to the influence of centrifugal force, and the water-based epoxy resin is uniformly stirred in cooperation with several stirring blades. At the same time, since the curing agent flows out intermittently from the output end of the L-shaped pipe 201, the outflow speed of the curing agent is slower, avoiding the rapid reaction between the curing agent and the water-based epoxy resin, which may cause uneven local curing or over-curing.
