Description

Technical Field

[0001] This utility model relates to the field of epoxy resin processing technology, and in particular to an epoxy resin curing agent synthesis device. Background Technology

[0002] The synthesis of epoxy resin and curing agent is inherently dangerous; accidental contact with skin can cause injury. Therefore, the device must possess a certain level of operational safety. Chinese Patent Application No. 202123076127.6 discloses a device for synthesizing epoxy resin curing agent, comprising a conical mixing chamber. Two feeding pipes are fixedly connected to the inner wall of the conical mixing chamber. The tops of both feeding pipes are fixedly connected to a feeding box fixedly connected to the top of the conical mixing chamber. A control box is fixedly connected to the top of the conical mixing chamber. A mixing mechanism is installed inside the conical mixing chamber. A switch cover assembly is installed at the bottom of the conical mixing chamber. Two rotating rods are fixedly connected to the outer side of the conical mixing chamber. A fixed box is movably connected to the end of each rotating rod away from the conical mixing chamber. A base plate is fixedly connected between the two fixed boxes. A control assembly is installed inside the right-side fixed box.

[0003] The aforementioned technology, by setting a bottom plate and control components at the bottom outlet of the mixing tank, presents several drawbacks. Firstly, when personnel open the bottom plate to control the discharge, they cannot control the discharge speed, affecting both operational safety and accuracy. Secondly, the control components are too close to the discharge point, keeping personnel's hands too close and posing a risk to their skin. Therefore, to address these shortcomings, we propose an epoxy resin curing agent synthesis device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an epoxy resin curing agent synthesis device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An epoxy resin curing agent synthesis device includes a base, a processing tank mounted on the upper surface of the base, a top cover at the upper end of the processing tank, a cylindrical mounting cavity at the upper part of the base and a spiral shaft mounted inside the mounting cavity, a motor corresponding to the spiral shaft mounted at one end of the base, a feed chute extending into the processing tank at the upper side of one end of the mounting cavity, a return pipe and a discharge pipe at the end of the mounting cavity away from the feed chute, the upper end of the return pipe extending to the upper end of the processing tank and penetrating into the processing tank, a spherical sealing cavity in the middle of the discharge pipe and a sealing ball mounted inside the sealing cavity, a discharge chute corresponding to the sealing ball and the discharge pipe, and a control lever corresponding to the sealing ball mounted in the middle of the discharge pipe.

[0007] Preferably, the base has a mounting hole at its lower part, and the control lever is rotatably mounted in the mounting hole.

[0008] Preferably, the base has a scale pattern on the side away from the sealing ball, and the control lever has a corresponding pointer on the end away from the sealing ball.

[0009] Preferably, the bottom surface of the processing tank is provided with an inclined guide surface, and the lower end of the guide surface is close to the feed trough.

[0010] Preferably, the upper surface of the top cover is provided with several limiting cylinders and connecting seats, and a limiting rod is inserted inside the limiting cylinder, with both ends of the limiting rod extending to the outside of the processing barrel.

[0011] Preferably, one end of the limiting rod located outside the processing barrel is connected to a linkage plate, and the other end of the limiting rod is provided with a pin.

[0012] Preferably, a sealing sleeve is provided on the lower side of the outer ring surface of the top cover, and a force-applying block is provided at the end of the control lever away from the sealing ball.

[0013] The epoxy resin curing agent synthesis device proposed in this utility model has the following advantages:

[0014] 1. In this utility model, the sealing ball is rotated by a control lever, thereby controlling the opening and closing of the discharge pipe. When the discharge pipe is closed, the material inside the processing tank is sucked into the mounting cavity of the base and flows back into the processing tank along the spiral shaft and the return pipe, thus achieving the stirring effect. When the discharge pipe is open, the material inside the mounting cavity enters the discharge groove of the sealing ball along the discharge pipe and is finally discharged, thus achieving the discharge effect. Simultaneously, the spiral shaft can accelerate or decelerate the material entering the discharge pipe, while the rotation of the sealing ball controls the space exposed in the discharge trough, thereby further controlling the speed at which the material is discharged from the discharge pipe. Thus, under the dual action of the spiral shaft and the sealing ball, personnel can conveniently and accurately control the discharge speed, preventing the material from being discharged too quickly and impacting the external collection facility and reflecting onto the ground or personnel, thus protecting personnel. Furthermore, since personnel operate the control lever, they are kept away from the discharge pipe, further protecting them. This solves the shortcomings of traditional solutions that cannot effectively protect personnel and cannot control the discharge speed.

[0015] 2. The scale and pointer in this utility model allow the operator to determine the rotation angle of the control lever, enabling them to accurately control the speed of the material discharge chute at the sealing ball. The guide surface facilitates the flow of material inside the processing tank into the installation cavity. The limiting cylinder and limiting rod fix the top cover position, while the connecting seat allows for easy movement of the top cover up and down by external telescopic components or manual operation. When the top cover moves upward, it separates from the processing tank, facilitating internal inspection. When the top cover moves downward, its edge scrapes against the inner wall of the processing tank, allowing residual material inside to move quickly downward, facilitating cleaning of the inner wall.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1

[0023] Reference Figures 1-4 An epoxy resin curing agent synthesis device includes a base 1, a processing tank 2 mounted on the upper surface of the base 1, a top cover 6 at the upper end of the processing tank 2, a cylindrical mounting cavity at the upper part of the base 1 and a spiral shaft 3 installed in the mounting cavity, a motor 11 corresponding to the spiral shaft 3 mounted at one end of the base 1, a feeding groove extending into the interior of the processing tank 2 at the upper side of one end of the mounting cavity, a return pipe 4 and a discharge pipe 5 at the end of the mounting cavity away from the feeding groove, the upper end of the return pipe 4 extending to the upper end of the processing tank 2 and penetrating into the interior of the processing tank 2, a spherical sealing cavity in the middle of the discharge pipe 5 and a sealing ball 7 installed in the sealing cavity, a feeding groove corresponding to the sealing ball 7 and a control lever 8 corresponding to the sealing ball 7 in the middle of the discharge pipe 5.

[0024] Example 2

[0025] Reference Figures 1-4 While all other parts are the same as in Example 1, the difference between this example and Example 1 is that:

[0026] The base 1 has a mounting hole at its lower part, and the control lever 8 is rotatably mounted in the mounting hole. The mounting hole can constrain the control lever 8, so that the control lever 8 can only rotate and cannot move back and forth, thus ensuring the stability of the sealing ball 7. The side of the base 1 away from the sealing ball 7 has scale markings, and the end of the control lever 8 away from the sealing ball 7 has a corresponding pointer 9. The scale markings and pointer 9 allow the angle of rotation of the control lever 8 to be determined, so that the personnel can know the angle of rotation of the sealing ball 7, thus facilitating the precise control of the speed of the material feeding trough at the sealing ball 7. The bottom surface of the processing tank 2 has an inclined guide surface 10, and the lower end of the guide surface 10 is close to the feeding trough. The guide surface 10 allows the material inside the processing tank 2 to flow into the installation cavity.

[0027] The upper surface of the top cover 6 is provided with several limiting cylinders 12 and connecting seats 13. Limiting rods 14 are inserted inside the limiting cylinders 12, with both ends of the limiting rods 14 extending to the outside of the processing tank 2. The limiting cylinders 12 and the limiting rods 14 facilitate fixing the position of the top cover 6. The connecting seats 13 allow connection to external telescopic components such as electric cylinders, hydraulic cylinders, and electric push rods, enabling external telescopic components or manual movement of the top cover 6 up and down. When the top cover 6 moves upward, it separates from the processing tank 2, facilitating access to the interior of the processing tank 2. During maintenance, when the top cover 6 moves down, the edge of the top cover 6 scrapes against the inner wall of the processing tank 2, which facilitates the rapid downward movement of the residual material inside the processing tank 2, thus making it easier to clean the inner wall of the processing tank 2; one end of the limiting rod 14 located outside the processing tank 2 is connected to the linkage plate 15, and the other end of the limiting rod 14 is provided with a pin. The setting of the linkage plate 15 makes it easy to pull out the limiting rod 14 at the same time, thereby facilitating the installation and removal of the top cover 6; a sealing sleeve is provided on the lower side of the outer ring surface of the top cover 6, and a force-applying block is provided on the end of the control rod 8 away from the sealing ball 7.

[0028] Operating principle and advantages: In use, the material for synthesizing epoxy resin curing agent is placed inside the processing tank 2. The operator rotates the sealing ball 7 using the control lever 8. As the sealing ball 7 rotates, the material trough in its center gradually becomes perpendicular to the discharge pipe 5, effectively sealing the discharge pipe 5. Under the rotation of the spiral shaft 3, the material inside the processing tank 2 is drawn into the mounting cavity of the base 1 by gravity and the spiral shaft 3, flowing along the spiral shaft 3 towards the return pipe 4. Then, pumped by the spiral shaft 3, it flows back into the processing tank 2 through the return pipe 4. This continuous inflow and outflow of material achieves a mixing effect. Furthermore, when discharge is required, simply rotate the control lever 8 to rotate the sealing ball 7 so that the material trough is parallel to the discharge pipe 5. The material inside the mounting cavity then flows along the discharge pipe 5 into the material trough of the sealing ball 7 and is finally discharged, thus achieving the discharge effect.

[0029] Furthermore, the spiral shaft 3 can accelerate or decelerate the material entering the discharge pipe 5, while the rotation of the sealing ball 7 controls the space exposed in the discharge trough, thereby further controlling the speed at which the material is discharged from the discharge pipe 5. Thus, under the dual action of the spiral shaft 3 and the sealing ball 7, personnel can conveniently and accurately control the discharge speed, thereby preventing the material from being discharged too quickly and impacting the external collection facility and reflecting onto the ground or personnel, thus protecting personnel. At the same time, since personnel operate the control lever 8, they are kept away from the discharge pipe 5, which further protects personnel.

[0030] Furthermore, the mounting hole design constrains the control lever 8, ensuring it can only rotate and not move forward or backward, thus guaranteeing the stability of the sealing ball 7. The scale and pointer 9 allow for the determination of the rotation angle of the control lever 8, enabling personnel to accurately control the speed of the material discharge chute at the sealing ball 7. The guide surface 10 facilitates the flow of material from the processing tank 2 into the mounting cavity. The limiting cylinder 12 and limiting rod 14... The top cover 6 is positioned to secure it in place. The connecting seat 13 allows for easy movement of the top cover 6 up and down by external telescopic components or manual operation. When the top cover 6 moves upward, it separates from the processing tank 2, facilitating internal inspection. When the top cover 6 moves downward, its edge scrapes against the inner wall of the processing tank 2, allowing residual material inside the tank to move downward quickly, thus facilitating cleaning of the inner wall. The linkage plate 15 allows for simultaneous removal of the limit rod 14, facilitating the installation and removal of the top cover 6.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
