Description

Technical Field

[0001] This utility model relates to the field of heating device technology, specifically a heating device for polyamide resin production. Background Technology

[0002] Polyamide resin is a high-molecular-weight polymer composed of amide bonds. The amide groups in its molecular chain structure endow the material with excellent heat resistance, mechanical strength, and chemical stability. The production process of polyamide resin requires heating to maintain the high-temperature environment necessary for its polymerization reaction.

[0004] The aforementioned device, by setting up inclined plates, a first guide tube, and a second guide tube, can achieve repeated stirring of polyamide resin production materials, making the materials more evenly heated. However, once the electric heater of the aforementioned device is fixed on the heating base, it is usually difficult to disassemble it separately. If the electric heater is damaged later, it is usually necessary to replace the entire heating base on which the electric heater is installed, resulting in high maintenance costs. Furthermore, during the guiding and conveying process, due to the stickiness of the material itself, the material is prone to accumulate inside the tube, causing blockage and affecting the smoothness of material conveying through the guide tube.

[0014] Compared with the prior art, the present invention provides a heating device for polyamide resin production, which has the following advantages:

[0015] 1. This heating device for polyamide resin production, by setting positioning components, connection ports, slots, and baffles, allows for the replacement of damaged heaters later. When a damaged heater needs to be replaced, the push rod is pushed so that the entire device is completely within the C-shaped frame. At the same time, the baffle is moved outward so that it disengages from the slots and the baffle in sequence, allowing the heater to be moved out from the opening on one side of the support box. This allows for the individual disassembly of the heater. The reverse operation allows for the installation of the heater. This facilitates the individual replacement of the heater and reduces the maintenance cost of the heater in the later stages.

[0016] 2. This heating device for polyamide resin production, by setting up a vibrating motor, a moving cavity, and an elastic ball, guides the material during the process of guiding and conveying it through the guide tube. When the vibrating motor is started, its own vibration can cause the inner wall of the guide tube to shake, which in turn can cause the elastic ball to bounce. The moving cavity is larger than the elastic ball, which can provide sufficient space for the elastic ball to bounce. The bounce of the elastic ball can improve the shaking effect of the inner wall of the guide tube, and the material is less likely to accumulate in the tube and cause blockage.

The movement of the fixing plate 902 can be controlled by the push rod 906.

[0025] In this embodiment, the barrel 2 is fixedly installed on the top of the support box 7, a suitable sealing cap is installed on the discharge pipe 6, the electric heater 8 is snapped into the support box 7 and its top is in contact with the bottom of the barrel 2, and one side of the support box 7 is open.

[0026] Specifically, the support box 7 facilitates the installation of the electric heater 8 and provides support for the barrel 2.

[0027] In this embodiment, the connection port 12, the slot 13 and the baffle 14 are adapted to each other. One end of the baffle 14 passes through the connection port 12 and is snapped into the slot 13. One side of the baffle 14 is in contact with the heater 8, and one side of the fixing plate 902 is in contact with the other end of the baffle 14.

[0028] Specifically, the baffle 14 can limit and fix the electric heater 8;

[0029] In this embodiment, the C-shaped frame 901 is fixedly installed on the support box 7 on one side of the connection port 12, one end of the spring 903 is fixedly installed on one side of the inner wall of the C-shaped frame 901, and one end of the fixing plate 902 extends into the C-shaped frame 901 and is fixedly installed on the other end of the spring 903.

[0030] Specifically, the C-frame 901 facilitates the installation of the fixing plate 902;

[0031] In this embodiment, mounting blocks 905 are fixedly installed at the top and bottom of the extended end of the fixed plate 902.

The two sets of mounting blocks 905 are respectively snapped into the two sets of mounting grooves 904. The push rod 906 is fixedly installed on one side of the extended end of the fixed plate 902.

[0032] Specifically, the mounting block 905 combined with the mounting groove 904 facilitates the movable installation of the fixing plate 902 and prevents the fixing plate 902 from detaching from the C-frame 901;

[0033] In this embodiment, the movable cavity 16 is spherical and larger than the elastic ball 17. The elastic ball 17 is placed inside the movable cavity 16 and is made of elastic rubber. The movable cavity 16 and the elastic ball 17 are provided in several sets and the number of both is the same.

[0034] Specifically, the movable cavity 16 can provide sufficient bounce space for the elastic ball 17;

[0035] In this embodiment, the vibration motor 15 is fixedly installed on one side of the first guide tube 10. The first guide tube 10 and the second guide tube 11 have the same structure. Both sets of vibration motors 15 are electrically connected to the same external controller.

[0036] Specifically, the vibration of the vibration motor 15 itself can cause the inner walls of the first guide tube 10 and the second guide tube 11 to vibrate.

[0037] The working principle and usage process of this utility model are as follows: The operator first checks whether the relevant components are installed in the correct position. The polyamide resin production material is conveyed into the barrel 2 through the feed pipe 4. The electric heater 8 can heat the bottom of the barrel 2, thereby heating the polyamide resin production material in the barrel 2. The stirring motor 5 can drive the stirring rod in the barrel 2 to rotate. The stirring rod can stir the material to make the material heat more evenly. The first guide pipe 10 can convey the stirred and heated material into the screw conveyor 3. The screw conveyor 3 can convey the material back into the barrel 2 through the second guide pipe 11, thereby realizing repeated stirring of the material and making the material heat more evenly.

[0038] When the damaged heater 8 needs to be replaced later, push the push rod 906 so that it is completely inside the C-shaped frame 901. At the same time, move the baffle 14 outward so that the baffle 14 disengages from the slot 13 and the baffle 14 in sequence. The heater 8 can be moved out from the opening on one side of the support box 7 to complete the individual disassembly of the heater 8. The above operation is reversed to complete the installation of the heater 8. This makes it convenient to replace the heater 8 individually without replacing the support box 7 (heating base of the heater 8) together, thereby reducing the maintenance cost of the heater 8 in the later stage.

[0039] Furthermore, during the material guiding and conveying process of the first guide tube 10 and the second guide tube 11, two sets of vibration motors 15 are started. The vibration of the vibration motor 15 itself can drive the inner wall of the first guide tube 10 and the second guide tube 11 to vibrate, which in turn can drive the elastic ball 17 to bounce. The moving cavity 16 is larger than the elastic ball 17, which can provide sufficient bouncing space for the elastic ball 17. The bouncing of the elastic ball 17 can improve the vibration effect of the inner wall of the guide tube, and the material is not easy to accumulate in the tube and cause blockage.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
