[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.
[0033] Reference Figure 1 - Figure 3 , the utility model provides an embodiment: a carburizer calcining furnace with a drying effect, including a calcining furnace 1, which serves as the basis of the entire equipment, provides heat and space for calcining treatment, is an existing structure, and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. A base 2 is arranged on the top of the calcining furnace 1, which plays a role in supporting and fixing the insulation tube 3 to ensure the stable placement of the insulation tube 3. The insulation tube 3 is fixedly connected to the top of the base 2, which can reduce heat loss, maintain the internal temperature, and improve the drying and calcining efficiency. An upper cover 4 is arranged on the top of the insulation tube 3 to seal the top of the insulation tube 3 to prevent heat loss and external impurities from entering. A reduction motor 5 is fixedly connected to the top of the upper cover 4 to provide power, and its output shaft rotates and vibrates to work. A feeding hopper is arranged on the left side of the top of the upper cover 4 for adding carburizer. The carbon enhancer can be discharged at the same time. A vibration component is arranged at the bottom end of the output shaft of the reduction motor 5. The vibration component comprises a connecting sleeve 61. As the output shaft rotates, the groove on its inner wall cooperates with the convex block on the outer wall of the rotating rod 62 to limit the rotation, thereby transmitting the rotation to the rotating rod 62. When the equipment needs to be maintained, the connecting sleeve 61 can be quickly detached from the rotating rod 62. The top of the connecting sleeve 61 is fixedly connected to the bottom end of the output shaft of the reduction motor 5. The outer wall of the connecting sleeve 61 penetrates and is rotatably connected to the inner wall at the top end of the upper cover 4. The inner wall at the bottom end of the connecting sleeve 61 is slidably connected to the rotating rod 62, and the rotational motion transmitted from the connecting sleeve 61 is transmitted to the drying barrel 63. The bottom end of the rotating rod 62 is fixedly connected to the drying barrel 63, and rotates in the heat preservation barrel 3 under the drive of the rotating rod 62, so that the carbon enhancer in the barrel can be evenly heated to achieve a drying effect. The outer side of the drying barrel 63 is slidably connected to the inner wall of the heat preservation barrel 3.
[0034] Reference Figure 2 - Figure 4The inner wall of the outer bottom end of the drying barrel 63 is provided with a ball bearing 64 to reduce the friction between the outer bottom end of the drying barrel 63 and the moving ring 65, making the rotation smoother. The bottom end of the ball bearing 64 is provided with a moving ring 65 to support the drying barrel 63 and play a certain buffering and stabilizing role under the action of the sliding rod 66 and the compression spring 67. The outer wall of the moving ring 65 is slidably connected to the inner wall of the insulation cylinder 3. The bottom end of the moving ring 65 is fixedly connected to the sliding rod 66 to guide the moving ring 65 to move up and down and ensure the stability of the movement. The sliding rod 66 is provided with multiple groups. The outer walls of the bottom ends of the multiple groups of sliding rods 66 are slidably connected to the inner wall of the insulation cylinder 3. The outer side of the sliding rod 66 is provided with a compression spring 67 to apply elastic force to the moving ring 65 to buffer the vibration of the drying barrel 63 during rotation. The top end of the compression spring 67 is fixedly connected to the bottom end of the moving ring 65, and the bottom end of the compression spring 67 is fixedly connected to the inner wall of the insulation cylinder 3.
[0035] Furthermore, a roller 68 is fixedly connected to the inner wall of the bottom end of the drying barrel 63, and rolls on the guide block 69 to reduce the friction of the bottom of the drying barrel 63. A guide block 69 is provided at the bottom end of the drying barrel 63, and one side of the guide block 69 is provided as an inclined surface, and the other side is a vertical surface. When the roller 68 rolls to the top of the guide block 69 through the inclined surface, it continues to move to the vertical surface. Through the weight of the drying barrel 63 and the carbon enhancer therein, the roller 68 quickly falls to the top of the collecting hopper 71, thereby vibrating the carbon enhancer inside the drying barrel 63, thereby promoting further dispersion and mixing between the carbon enhancer particles, and improving The drying efficiency is improved, thereby improving the calcination efficiency of the carbon enhancer. A through hole is opened through the bottom of the drying barrel 63. During the drying process, it is helpful for hot air to circulate in the drying barrel 63, so that the material is heated more evenly and the drying effect is improved. A discharge port 7 is opened through the middle of the bottom of the drying barrel 63 for discharging the carbon enhancer. A baffle 6 is fixedly connected to the inner wall of the upper side of the insulation cylinder 3. The baffle 6 extends to the inside of the drying barrel 63. When the drying barrel 63 rotates, the baffle 6 will block the material in the drying barrel 63 to ensure that the material can fully contact with the hot air, thereby further improving the uniformity and efficiency of drying.
[0036] Reference Figure 2 , Figure 4 and Figure 6The inner wall of the heat preservation cylinder 3 is provided with a drying assembly, and the drying assembly includes a collecting hopper 71 for collecting the carburizer falling from the discharge port 7. The outer wall of the collecting hopper 71 is fixedly connected to the inner wall of the heat preservation cylinder 3. The inner wall of the collecting hopper 71 is penetrated with ventilation holes. There are multiple groups of ventilation holes, which can circulate hot air to the through holes at the bottom of the drying barrel 63. At the same time, the undried carburizer that directly falls into the collecting hopper 71 can be dried again. The right side of the heat preservation cylinder 3 is penetrated and fixedly connected with a heating pipe 72. The bottom right end of the heating pipe 72 passes through and is fixedly connected to the inner wall of the calcining furnace 1, and can transport the heat generated by the calcining furnace 1 to the insulation tube 3 to provide hot air for drying. The outer wall of the heating pipe 72 is provided with an insulation layer to reduce the heat loss of the heating pipe 72 during the hot air transportation process. An electric heating pipe 73 is provided at the top of the base 2 to heat the air, thereby improving the drying efficiency. The top of the collecting hopper 71 is fixedly connected to the bottom end of the guide block 69, and the outer wall of the roller 68 rolls on the upper surface of the guide block 69.
[0037] Reference Figure 1 Figure 2 and Figure 5 The inner wall of the heat preservation tube 3 is provided with a quantitative component, which includes an electric telescopic rod 81. By receiving the signal of the weight sensor 84, the output shaft thereof is driven to perform a telescopic action, thereby driving the pull plate 82 to move. The bottom end of the electric telescopic rod 81 is slidably connected to the top of the calcining furnace 1. The right side of the output shaft of the electric telescopic rod 81 is fixedly connected with a pull plate 82 for connecting the output shaft of the electric telescopic rod 81 and a connecting plate 83. The outer wall of the pull plate 82 is slidably connected to the inner wall of the heat preservation tube 3. A discharge hole is opened through the middle of the heat preservation tube 3. A chute is opened near the discharge hole of the heat preservation tube 3. The opening height of the chute is higher than that of the calcining furnace 1. The connecting plate 83 is higher, so that the connecting plate 83 can rotate to a certain extent. The connecting plate 83 is hinged on the right side of the pull plate 82 for controlling the opening and closing of the discharge hole. The connecting plate 83 slides on the inner wall of the slide slot. A weight sensor 84 is provided at the bottom right end of the slide slot. The bottom right end of the connecting plate 83 is attached to the top of the weight sensor 84. The weight sensor 84 is used to detect the pressure transmitted by the connecting plate 83, so as to achieve quantitative control of the discharge amount. The left side of the top of the weight sensor 84 is set as an inclined surface, so that the connecting plate 83 can quickly slide to the top of the weight sensor 84 through the inclined surface when resetting.
[0038] Working principle: When in use, first add the carburizer into the drying barrel 63 through the feed hopper, start the reduction motor 5, and its output shaft drives the connecting sleeve 61 to rotate. The connecting sleeve 61 drives the rotating rod 62 to rotate by cooperating with the rotating rod 62, so that the drying barrel 63 rotates in the insulation cylinder 3.
[0039] When the drying barrel 63 rotates, the baffle 6 stirs and turns the material to make it heated more evenly. The roller 68 at the bottom of the drying barrel 63 rolls on the guide block 69. When the roller 68 rolls from the inclined surface of the guide block 69 to the vertical surface, the weight of the drying barrel 63 and the internal carburizer causes the roller 68 to fall quickly, vibrating the carburizer inside the drying barrel 63, promoting particle dispersion and mixing, and improving drying efficiency. At the same time, the heat generated by the calcining furnace 1 is transported to the insulation tube 3 through the heating pipe 72. After the hot air is heated by the electric heating pipe 73, it passes through the ventilation holes of the collecting hopper 71 and the through holes at the bottom of the drying barrel 63 to fully contact with the carburizer to achieve uniform drying.
[0040] After drying is completed, the recarburizer falls into the collecting hopper 71 from the discharge port 7 in the middle of the bottom end of the drying barrel 63, and the recarburizer falls on the connecting plate 83. The pressure transmitted by the connecting plate 83 is detected by the weight sensor 84 to control the movement of the electric telescopic rod 81. When the set discharge amount is reached, the electric telescopic rod 81 drives the pull plate 82 to move, and the pull plate 82 slides in the slide groove through the hinged connecting plate 83 to open the discharge hole in the middle of the insulation cylinder 3 to achieve quantitative discharge.
[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
