Description

Technical Field

[0001] The utility model relates to the field of epoxy resin preparation, in particular to a device for preparing epoxy resin emulsion. Background Art

[0002] In the preparation process of existing epoxy resins, epoxy resin liquid and graphene oxide aqueous solution need to be mixed. After the mixing is completed, the mixed liquid needs to be transferred to a reactor for the final preparation of epoxy resin emulsion.

[0003] Known reactors are usually composed of a reactor, a stirring rod, a feed port, a discharge port and a valve. When in use, the materials required for epoxy resin preparation are poured into the reactor through the feed port and stirred by the stirring rod. However, since the epoxy resin is viscous and has a certain viscosity, when the epoxy resin is prepared and needs to be discharged, the valve on the discharge pipe is usually opened to allow the epoxy resin to be discharged through the discharge pipe. During this process, a portion of the epoxy resin is easily adhered to the inner wall of the discharge pipe, which is not only impossible to clean in time, but also the epoxy resin is easily accumulated for a long time, causing blockage inside the discharge pipe.

[0004] Therefore, it is necessary to invent a preparation device for epoxy resin emulsion. Utility Model Content

[0005] The purpose of the utility model is to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical scheme: a device for preparing epoxy resin emulsion, comprising a reactor, a top cover is installed on the upper end of the reactor, a stirring rod is installed between the reactor and the top cover, a rotating gear is installed outside the upper end of the stirring rod, an adjusting screw is connected in the middle of the upper end of the stirring rod, a clearing component is installed at the lower end of the adjusting screw, the clearing component is located at the lower end of the inner cavity of the stirring rod, a discharge pipe is installed at the bottom of the reactor, and a ball valve is installed in the middle of the discharge pipe.

[0007] Based on the above characteristics: when the emulsion mixing is completed, the container is placed at the lower end of the discharge pipe, and then the ball valve can be opened to allow the prepared epoxy resin emulsion to fall and be discharged through the discharge pipe. When the epoxy resin emulsion is blocked inside the discharge pipe, the adjusting screw can be driven to rotate. At this time, the adjusting screw can drive the dredging component to move downward, so that the dredging component passes through the discharge pipe and the ball valve to dredge, thereby avoiding blockage of the discharge pipe during discharge.

[0008] Preferably, a feed port is installed on one side of the upper end of the top cover, a driving gear is installed on one side of the upper end of the top cover, and a driving motor is installed on the upper end of the driving gear.

[0009] Based on the above characteristics: epoxy resin emulsion and other emulsions that need to be mixed are poured into the reactor through the feed port. When the drive motor is started, the rotating shaft at the output end will drive the drive gear to rotate, and the drive gear will mesh with the rotating gear, making it convenient for the rotating gear to drive the stirring rod and the adjusting screw to rotate synchronously.

[0010] Preferably, a stirring blade is installed outside the stirring rod.

[0011] Based on the above characteristics: when the stirring rod rotates, the epoxy resin emulsion to be prepared in the reaction kettle will be stirred by the stirring blades.

[0012] Preferably, the stirring rod is a hollow tubular structure with openings at both ends.

[0013] Based on the above characteristics: the adjusting screw is connected to the upper end of the stirring rod, and the unblocking assembly is connected to the lower end of the stirring rod. When the adjusting screw moves upward, the unblocking assembly will also move upward and retract to the lower end of the inner cavity of the stirring rod. When the adjusting screw moves downward, the adjusting screw will be located at the upper end of the inner cavity of the stirring rod, and the unblocking assembly will also descend and be inserted into the discharge pipe.

[0014] Preferably, a fixing nut is installed in the middle of the upper end of the rotating gear, and the adjusting screw is threadedly connected to the fixing nut.

[0015] Based on the above characteristics: the fixing nut facilitates the locking and adjustment of the adjusting screw, thereby preventing the adjusting screw from loosening or self-displacing after rotation and adjustment.

[0016] Preferably, the dredging assembly includes a spiral rod and a spiral blade installed outside the spiral rod, a guide seat is installed at the lower end of the spiral rod, and a sealing plate is installed at the lower end of the guide seat.

[0017] Based on the above characteristics: when the adjusting screw rotates, it will synchronously drive the spiral rod and the spiral blade to rotate. At this time, the spiral rod and the spiral blade can not only dredge the inside of the discharge pipe, but also discharge the material evenly.

[0018] Preferably, the guide seat has a conical structure and is made of stainless steel.

[0019] Based on the above characteristics: when the spiral rod and the spiral blade rotate downward, the epoxy resin emulsion can be guided through the guide seat with a conical structure to avoid the epoxy resin emulsion from accumulating on the upper end of the sealing plate as much as possible.

[0020] The beneficial effects of the utility model are:

[0021] 1. Try to avoid blockage of epoxy resin emulsion when discharging in the discharge pipe. After the epoxy resin emulsion is stirred, stop the rotation of the stirring rod, then place the container at the lower end of the discharge pipe, and open the ball valve to allow the prepared epoxy resin emulsion to fall and be discharged through the discharge pipe. When blockage occurs inside the discharge pipe, the adjusting screw can be rotated downward alone, and the adjusting screw will also drive the spiral rod and spiral blades to rotate and move downward synchronously, so that the spiral rod and spiral blades can be inserted into the discharge pipe and the ball valve for unblocking.

[0022] 2. The guide seat has a conical structure, which makes it convenient for the spiral rod and spiral blades to rotate downward, so that the epoxy resin emulsion can be guided through the conical guide seat to avoid the epoxy resin emulsion from accumulating on the upper end of the sealing plate. When the dredging component moves up and retracts into the inner cavity of the stirring rod, the spiral rod can block the lower end of the stirring rod through the guide seat and the sealing plate to avoid the epoxy resin emulsion from entering the inner cavity of the stirring rod when the stirring rod rotates and stirs inside the reactor.

It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0029] Refer to the attached Figure 1-4The utility model provides a preparation device for epoxy resin emulsion, comprising a reactor 1, a top cover 2 is installed on the upper end of the reactor 1, a stirring rod 3 is installed between the reactor 1 and the top cover 2, a rotating gear 4 is installed on the outer upper end of the stirring rod 3, an adjusting screw 5 is connected to the middle of the upper end of the stirring rod 3, a dredging component 6 is installed at the lower end of the adjusting screw 5, the dredging component 6 is located at the lower end of the inner cavity of the stirring rod 3, a discharge pipe 7 is installed at the bottom of the reactor 1, and a ball valve 8 is installed in the middle of the discharge pipe 7.

[0030] Pour the epoxy resin emulsion and other emulsions that need to be mixed into the reactor 1, and then drive the rotating gear 4 to drive the stirring rod 3 to rotate, so that the stirring rod 3 can mix and stir the emulsion inside the reactor 1. When the emulsion mixing is completed, place the container at the lower end of the discharge pipe 7, and then open the ball valve 8 to allow the prepared epoxy resin emulsion to fall and be discharged through the discharge pipe 7. When the epoxy resin emulsion is blocked inside the discharge pipe 7, the adjusting screw 5 can be driven to rotate. At this time, the adjusting screw 5 can drive the dredging component 6 to move downward, so that the dredging component 6 passes through the discharge pipe 7 and the ball valve 8 to dredge, thereby avoiding the blockage of the discharge pipe 7 during discharge.

[0031] Preferably, a feed port 21 is installed on one side of the upper end of the top cover 2 , a driving gear 22 is installed on one side of the upper end of the top cover 2 , and a driving motor 23 is installed on the upper end of the driving gear 22 .

[0032] Epoxy resin emulsion and other emulsions that need to be mixed are poured into the reactor 1 through the feed port 21. When the driving motor 23 is started, the driving gear 22 will be driven to rotate through the shaft rotating at the output end, and the driving gear 22 will mesh with the rotating gear 4, so as to synchronously drive the rotating gear 4 to rotate. When the rotating gear 4 rotates, the rotating gear 4 will drive the stirring rod 3 and the adjusting screw 5 to rotate synchronously, so that the adjusting screw 5 will not move up and down by itself. When the stirring rod 3 stops rotating, the adjusting screw 5 can be rotated up and down alone (the adjusting screw 5 can be rotated manually or driven by a motor. This application does not make specific limitations and can be set as needed).

[0033] Preferably, a stirring blade 31 is installed outside the stirring rod 3 .

[0034] When the stirring rod 3 rotates, the epoxy resin emulsion to be prepared in the reaction kettle 1 is stirred by the stirring blades 31 .

[0035] Preferably, the stirring rod 3 is a hollow tubular structure with openings at both ends.

[0036] The adjusting screw 5 is connected to the upper end of the stirring rod 3, and the clearing assembly 6 is connected to the lower end of the stirring rod 3. When the adjusting screw 5 moves upward, the clearing assembly 6 will also move upward and retract to the lower end of the inner cavity of the stirring rod 3. When the adjusting screw 5 moves downward, the adjusting screw 5 will be located at the upper end of the inner cavity of the stirring rod 3, and the clearing assembly 6 will also descend and be inserted into the discharge pipe 7.

[0037] Preferably, a fixing nut 41 is installed in the middle of the upper end of the rotating gear 4 , and the adjusting screw 5 is threadedly connected to the fixing nut 41 .

[0038] The fixing nut 41 facilitates locking and adjusting of the adjusting screw 5, thereby preventing the adjusting screw 5 from loosening or self-displacing after rotation and adjustment.

[0039] Preferably, the dredging component 6 includes a spiral rod 61 and a spiral blade 62 installed outside the spiral rod 61 , a guide seat 63 is installed at the lower end of the spiral rod 61 , and a sealing plate 64 is installed at the lower end of the guide seat 63 .

[0040] When the adjusting screw 5 rotates, it will synchronously drive the screw rod 61 and the spiral blade 62 to rotate. At this time, the screw rod 61 and the spiral blade 62 can not only clear the inside of the discharge pipe 7, but also discharge the material evenly. When the clearing component 6 moves up and retracts into the inner cavity of the stirring rod 3, the screw rod 61 can seal the lower end of the stirring rod 3 through the guide seat 63 and the sealing plate 64, so as to avoid the epoxy resin emulsion from entering the inner cavity of the stirring rod 3 when the stirring rod 3 rotates and stirs inside the reactor 1.

[0041] Preferably, the guide seat 63 has a conical structure and is made of stainless steel.

[0042] When the spiral rod 61 and the spiral blade 62 rotate downward, the epoxy resin emulsion can be guided through the guide seat 63 with a conical structure to avoid the epoxy resin emulsion from accumulating on the upper end of the sealing plate 64 as much as possible.

[0043] The use process of the utility model is as follows: the epoxy resin emulsion and other emulsions to be mixed are poured into the reactor 1 through the feed port 21, and the drive motor 23 is started to drive the drive gear 22 to rotate, and the drive gear 22 is meshed with the rotating gear 4, so that the rotating gear 4 can drive the stirring rod 3 and the adjusting screw 5 to rotate synchronously. At this time, the stirring rod 3 will stir the epoxy resin emulsion to be prepared in the reactor 1 through the stirring blade 31. When the epoxy resin emulsion is stirred, the stirring rod 3 is stopped from rotating, and then the container is placed at the lower end of the discharge pipe 7, and the ball valve 8 is opened to complete the preparation. The epoxy resin emulsion falls and is discharged through the discharge pipe 7. When the epoxy resin emulsion is blocked inside the discharge pipe 7, the adjusting screw 5 can be rotated downward alone, and the adjusting screw 5 will also drive the spiral rod 61 and the spiral blade 62 to rotate downward synchronously, so that the spiral rod 61 and the spiral blade 62 are inserted into the discharge pipe 7 and the ball valve 8 for dredging. When the dredging is completed, the adjusting screw 5 can be rotated upward, and the adjusting screw 5 will also drive the spiral rod 61 and the spiral blade 62 to retract to the lower end of the inner cavity of the stirring rod 3, and the spiral rod 61 can block the lower end of the stirring rod 3 through the guide seat 63 and the sealing plate 64.

[0044] The above is only a preferred embodiment of the utility model. Any person skilled in the art may modify the utility model by using the above technical solution or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement based on the technical solution of the utility model shall fall within the scope of protection claimed by the utility model.
