Description

Technical Field

[0001] The utility model relates to the technical field of metal casting, in particular to a production device for a heating riser shrinkage feeding agent. Background Art

[0002] Exothermic riser shrinkage feeder is a material used to repair risers and shrinkage cavities generated during the casting process. Its main function is to solve casting defects caused by uneven cooling of castings or insufficient gas discharge by filling the positions of risers and shrinkage cavities during the casting process. Exothermic riser shrinkage feeder is produced by mixing raw materials and additives through a series of process steps, and then heating and mixing reactions are carried out to finally form a liquid product that can repair leaks in the engine or cooling system;

[0003] Traditional exothermic riser shrinkage-feeding agent production devices usually add various raw materials into a mixing tank one by one according to the formula ratio, and use a single-chip computer to control the operation of the electric motor. The output shaft of the motor rotates to drive the mixing frame and the stirring rod to rotate. As the mixing frame and the stirring rod rotate, the raw materials are pushed and pulled to achieve uniform mixing. Heat is provided by the heating equipment, and the raw materials undergo chemical changes under heating conditions, and finally form an exothermic riser shrinkage-feeding agent product suitable for the casting process requirements;

[0004] The traditional production device of exothermic riser shrinkage-feeding agent has the following problems: due to the use of a single stirring frame and stirring rod, it may not be possible to ensure that the raw materials are fully and evenly mixed in the mixing tank, especially for raw materials with high viscosity or large particles, which may cause uneven mixing, thereby affecting the quality of the final exothermic riser shrinkage-feeding agent. For this reason, we propose a production device of exothermic riser shrinkage-feeding agent. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for producing a heat-generating riser shrinkage-feeding agent, comprising legs and a stirring mechanism;

[0007] Legs: There are four legs, the tops of which are fixedly connected to the lower surface of a mixing barrel, the inner wall of the mixing barrel is provided with a mounting groove, and the inner wall of the mounting groove is provided with an electric heating wire;

[0008] Stirring mechanism: It includes a stirring rod, a stirring frame, a slide cylinder and a rotating shaft. The rotating shaft is rotatably connected to the top wall of the mixing barrel. The bottom end of the rotating shaft is fixedly connected to the stirring frame. The outer surface of the stirring frame is slidably connected to four slide cylinders. The outer surfaces of the four slide cylinders are fixedly connected to stirring rods evenly distributed.

[0009] Among them: it also includes a single-chip microcomputer, which is arranged at the front end of the outer surface of the mixing barrel, and the output end of the single-chip microcomputer is electrically connected to the input end of the electric heating wire, which can more quickly achieve a uniform mixing state of the raw materials, effectively avoid the problem of uneven local mixing of raw materials with high viscosity or large particles, and ensure the stability and reliability of the quality of the heating riser shrinkage feeding agent.

[0010] Furthermore, a feed hopper is fixedly connected to the feed port at the right end of the upper surface of the mixing barrel, and a discharge pipe is fixedly connected to the discharge port in the middle of the lower surface of the mixing barrel. A valve is connected in series in the middle of the discharge pipe to facilitate the entry and exit of the heating riser shrinkage compensation agent raw materials.

[0011] Furthermore, it also includes an exhaust pipe, which is fixedly connected to the exhaust hole at the right end of the outer surface of the mixing barrel. The right end of the exhaust pipe is provided with an air valve to adjust the internal air pressure of the mixing barrel.

[0012] Furthermore, the stirring mechanism also includes a pulley, an annular groove and a rotating shaft. The annular groove is opened in the middle of the inner wall of the mixing barrel. The rotating shaft is fixedly connected to one end of the four slides away from the center of the rotating shaft. The outer ends of the rotating shafts are rotatably connected to pulleys. The outer surfaces of the pulleys are slidably connected to the inner wall of an annular groove, so that the stirring rod has the ability to move up and down during rotation.

[0013] Furthermore, the annular chute has an inclination angle of 10 degrees, which effectively controls the stirring depth and frequency of the stirring rod.

[0014] Furthermore, the stirring mechanism also includes a spring and a limit block 1, the limit block 1 is fixedly connected to the top of the stirring frame, and a spring is fixedly connected between the lower surface of the limit block 1 and the upper surface of the slide cylinder, and between the upper surface of the stirring frame and the lower surface of the slide cylinder.

[0016] Compared with the prior art, the beneficial effects of the utility model are: the exothermic riser shrinkage feeding agent production device has the following advantages:

[0017] The rotation of the slide barrel will cause the pulley on it to slide in the annular slide groove with an inclined angle. As the angle of the annular slide groove changes, the slide barrel moves up and down along the stirring frame during rotation. However, the change in the inclination angle of the annular slide groove can control the position of the pulley in the slide groove, thereby adjusting the up and down movement speed and range of the slide barrel, and effectively controlling the stirring depth and frequency of the stirring rod. When the slide barrel moves upward, the spring at the upper end is compressed and the spring at the lower end is stretched. The compression and stretching of the spring can provide a balanced force reaction, which helps to smoothly control the rising and falling movement of the slide barrel, thereby realizing the up and down reciprocating movement of the slide barrel, and enabling the stirring rod to have the ability to move up and down during rotation, thereby increasing the frequency and range of mixing raw materials for the production of heat riser shrinkage agent, and can more quickly achieve a uniform mixing state of the raw materials, effectively avoiding the problem of local uneven mixing of raw materials with high viscosity or large particles, and ensuring the stability and reliability of the quality of the heat riser shrinkage agent.

Then, these raw materials are poured into the feed hopper 8 according to a predetermined formula ratio.

A discharge pipe 4 is fixedly connected to the discharge port in the middle of the lower surface of the mixing barrel 1. A valve 5 is connected in series in the middle of the discharge pipe 4. After mixing, the valve 5 is opened and the raw materials are discharged through the discharge pipe 4. The mixed exothermic riser shrinkage-feeding agent is discharged, and an exhaust pipe 7 is also included. The exhaust pipe 7 is fixedly connected to the exhaust hole at the right end of the outer surface of the mixing barrel 1. The right end of the exhaust pipe 7 is provided with an air valve 6. During the heating process, the air pressure inside the mixing barrel 1 is adjusted by the air valve 6. The inner wall of the mixing barrel 1 is provided with a mounting groove 11. The inner wall of the mounting groove 11 is provided with an electric heating wire 10. The operation of the electric heating wire 10 is regulated by the single-chip microcomputer 2. The electric heating wire 10 heats the inside of the mixing barrel 1, so that the raw materials in the mixing barrel 1 are heated to the required temperature, ensuring that the raw materials can be fully mixed and reacted;

[0026] Stirring mechanism 9: It includes a stirring rod 905, a stirring frame 906, a slide 907 and a rotating shaft 910. The rotating shaft 910 is rotatably connected to the top wall of the mixing barrel 1. The bottom end of the rotating shaft 910 is fixedly connected to the stirring frame 906. The outer surface of the stirring frame 906 is slidably connected to four slides 907. The outer surfaces of the four slides 907 are fixedly connected to uniformly distributed stirring rods 905. The stirring mechanism 9 also includes a pulley 902, an annular chute 903 and a rotating shaft 904. The annular chute 903 is opened in the middle of the inner wall of the mixing barrel 1. The rotating shaft 904 is fixedly connected to the mixing frame 906. The outer ends of the rotating shafts 904 are rotatably connected to the pulleys 902, and the outer surfaces of the pulleys 902 are slidably connected to the inner walls of an annular slide groove 903, and the annular slide groove 903 has an inclination angle of 10 degrees. The stirring mechanism 9 also includes a spring 908 and a limit block 909, and the limit blocks 909 are fixedly connected to the top of the stirring frame 906. The lower surface of the limit block 909 is fixedly connected to the upper surface of the slide 907, and the upper surface of the stirring frame 906 is fixedly connected to the lower surface of the slide 907. The stirring mechanism 9 further comprises a motor 901, which is mounted on the middle of the upper surface of the mixing barrel 1 by bolts. The bottom end of the output shaft of the motor 901 is fixedly connected to the top end of the rotating shaft 910. The input end of the motor 901 is electrically connected to the output end of the single chip microcomputer 2. The single chip microcomputer 2 controls the operation of the motor 901. The rotation of the output shaft of the motor 901 drives the rotating shaft 910 to rotate. The rotating shaft 910 drives the stirring frame 906, the slide cylinder 907 and the stirring rod 905 to rotate together, so as to stir the raw materials. Preliminary stirring and mixing is performed. In addition, the rotation of the slide 907 causes the pulley 902 thereon to slide in the annular slide groove 903 with an inclined angle. As the angle of the annular slide groove 903 changes, the slide 907 moves up and down along the stirring frame 906 during the rotation process. When the slide 907 moves upward, the spring 908 at the upper end is compressed and the spring 908 at the lower end is stretched, thereby realizing the up and down reciprocating motion of the slide 907, which enables the stirring rod 905 to have the ability to move up and down during the rotation process, thereby realizing a uniform mixing state of the raw materials more quickly.

[0028] The working principle of a heat-generating riser shrinkage-feeding agent production device provided by the utility model is as follows: first, various raw materials are prepared according to the required chemical composition and properties, and then, these raw materials are poured into the feed hopper 8 according to a predetermined formula ratio. Under the action of the feed hopper 8, the raw materials will fall into the interior of the mixing barrel 1. Next, the operation of the electric heating wire 10 is regulated by the single-chip microcomputer 2. The electric heating wire 10 will heat the interior of the mixing barrel 1, so that the raw materials in the mixing barrel 1 are heated to the required temperature to ensure that the raw materials can be fully mixed and reacted. During the heating process, the air pressure inside the mixing barrel 1 is adjusted by the air valve 6. At this time, the operation of the motor 901 is controlled by the single-chip microcomputer 2, and the rotation of the output shaft of the motor 901 drives the rotation shaft 910 to rotate, and the rotation shaft 910 drives The stirring frame 906, slide 907 and stirring rod 905 rotate together to preliminarily stir and mix the raw materials. In addition, the rotation of slide 907 causes the pulley 902 thereon to slide in the annular slide groove 903 with an inclined angle. As the angle of the annular slide groove 903 changes, the slide 907 moves up and down along the stirring frame 906 during rotation. When the slide 907 moves upward, the spring 908 at the upper end is compressed and the spring 908 at the lower end is stretched, thereby realizing the up and down reciprocating motion of the slide 907, which enables the stirring rod 905 to have the ability to move up and down during the rotation process, thereby realizing a uniform mixing state of the raw materials more quickly. After the mixing is completed, the valve 5 is opened to discharge the mixed exothermic riser shrinkage-feeding agent through the discharge pipe 4.
