Description

Technical Field

[0001] This utility model relates to a heating device for a material mixer. Background Technology

[0002] In the process of producing polyester colored yarn using the solution dyeing method, a crucial piece of equipment is the material mixer (dynamic mixer), which is the heating device for the material mixer mentioned above. During polyester colored yarn production, frequent shutdowns are required to switch product types, necessitating a shutdown of the dynamic mixer as well. However, restarting often results in prolonged downtime due to the dynamic mixer's inability to start immediately, impacting production efficiency. The reason for this inability to start immediately is that during shutdown, the material within the mixer stops flowing, and the material near both ends of the mixer solidifies, creating significant resistance and preventing immediate startup.

[0003] The current method involves using insulation blankets to heat both ends of the dynamic mixer for at least four hours. After insulation, the dynamic mixer is jogged, and operation resumes when the running current drops below the motor's rated current. This traditional method is time-consuming, inefficient, wastes manpower, affects production efficiency, and is unstable. Utility Model Content

[0032] See Figures 1 to 5 The material mixer heating device shown has a material mixer 14 with two opposing ends, each end of which has a cylindrical protrusion. The material mixer heating device includes a heating unit 13, a start-up control circuit, a heating circuit, and a heating control circuit, wherein:

[0033] Heating unit 13 is used to heat one end of material mixer 14. Heating unit 13 is circumferentially arranged around one end of material mixer 14 and outside one end of material mixer.

[0034] In some embodiments, the heating unit 13 includes a first half-heating jacket and a second half-heating jacket, which are arranged in a ring at one end of the material mixer 14. One end of the first half-heating jacket is opposite to one end of the second half-heating jacket and is detachably connected by a fastener 16, and the other end of the first half-heating jacket is opposite to the other end of the second half-heating jacket and is detachably connected by a fastener 16.

[0035] Specifically, the first half-heating sleeve includes a first body 131, with first connecting ears 132 spaced apart at opposite ends of the first body 131, and mounting holes formed on the first connecting ears 132. The second half-heating sleeve includes a second body 133, with second connecting ears 134 spaced apart at opposite ends of the second body 133, and mounting holes formed on the second connecting ears 134. The first half-heating sleeve and the second half-heating sleeve are connected by installing fasteners 16 in the mounting holes of the first connecting ears 132 and the corresponding mounting holes of the second connecting ears 134. When disassembling the heating unit 13, the first half-heating sleeve and the second half-heating sleeve can be separated and disassembled by removing the fasteners 16. The installation and disassembly of the heating unit 13 are both convenient.

[0036] In some embodiments, fastener 16 includes bolts and nuts.

[0037] In this example, the start-up control circuit includes a first miniature circuit breaker 1, a first switch 4, a normally closed contact 5 of an intermediate relay, and an AC contactor coil 6. The first miniature circuit breaker 1, the first switch 4, the normally closed contact 5 of the intermediate relay, and the AC contactor coil 6 are connected in series and between the live wire and the neutral wire of the power supply. See also... Figure 1 The first miniature circuit breaker 1, the first switch 4, the normally closed contact 5 of the intermediate relay, and the AC contactor coil 6 are connected in sequence. One end of the first miniature circuit breaker 1 is connected to the live wire of the power supply, and the AC contactor coil 6 is connected to the neutral wire of the power supply.

[0038] The heating circuit includes a second miniature circuit breaker 2, AC contactor main contacts 9, a solid-state relay 10, and a heating unit 13. The second miniature circuit breaker 2, AC contactor main contacts 9, solid-state relay 10, and heating unit 13 are connected in series and between the live wire and neutral wire of the power supply. (See [reference]). Figure 1 The second miniature circuit breaker 2, the AC contactor main contact 9, the solid-state relay 10, and the heating unit 13 are connected in sequence. One end of the second miniature circuit breaker 2 is connected to the live wire of the power supply. The solid-state relay 10 has a first terminal ( Figure 1 The middle 1 refers to), the second end ( Figure 1 The third end (as indicated in point 2) Figure 1 The third point refers to the fourth end ( Figure 1 (Referring to point 4 in the diagram), the first terminal is connected to one end of the main contact 9 of the AC contactor, the second terminal is connected to the heating unit 13, and the third terminal is connected to the negative power output of the temperature controller 15 and the positive power output of the temperature controller 15. In some embodiments, the temperature controller 15 outputs a 12V voltage to the solid-state relay 10.

[0039] In this example, the first switch 4 is a rotary switch.

[0040] In a preferred embodiment, heating units 13 are provided at both ends of the material mixer. One heating unit 13 is connected in series with the second miniature circuit breaker 2, the main contact 9 of the AC contactor, and the solid-state relay 10, and the other heating unit 13 is connected in parallel with the heating unit 13.

[0041] The heating control circuit includes a third miniature circuit breaker 3, a temperature controller 15, and a temperature detection unit 11. One end of the third miniature circuit breaker 3 is connected to the live wire of the power supply, and the other end is connected to the temperature controller 15. The temperature detection unit 11 is connected to the temperature controller 15 and is used to detect the temperature of the heating unit 13. The intermediate relay coil 12 is connected to the power supply through the temperature controller 15.

[0042] In this example, the temperature detection unit 11 is a platinum electrode, which is connected to the heating unit 13. The power supply voltage is transmitted to the temperature controller 15 via wires, and the resistance signal of the platinum electrode is fed back to the temperature controller 15 via wires. The temperature controller 15 sends a signal to the solid-state relay 10 through PID regulation to control the opening and closing of its contacts, thereby controlling the heating. When the temperature of the heating unit 13 is lower than the set temperature, the temperature controller 15 outputs a closing control signal to the solid-state relay 10, that is, the solid-state relay 10 is turned on.

[0043] See Figure 1 The temperature controller 15 has a first power supply terminal and a second power supply terminal. The first power supply terminal of the temperature controller 15 is connected to the third miniature circuit breaker 3, and the second power supply terminal is connected to the neutral wire. The temperature controller 15 also has a first terminal, a second terminal, and a third terminal. The temperature detection unit 11 has a first terminal, a second terminal, and a third terminal. The first terminal, the second terminal, and the third terminal of the temperature controller 15 are respectively connected to the first terminal, the second terminal, and the third terminal of the temperature detection unit 11.

[0044] In this example, the temperature controller 15 is set to control the temperature. The output voltage signal of the temperature controller 15 controls the solid-state relay 10 to conduct, so that the power supply voltage passes through the second miniature circuit breaker 2, AC contactor 9, and solid-state relay 10 to one heating unit 13 and another heating unit 13 to heat up the temperature, thereby realizing the end heating of the material mixer 14. The structure is simple and easy to operate.

[0045] The working principle of the material mixer heating device in this example is as follows:

[0046] 1. Power on the first miniature circuit breaker QF1, the second miniature circuit breaker QF2, and the third miniature circuit breaker QF3;

[0047] 2. When the first switch SB1 is turned, the power supply voltage passes through the first miniature circuit breaker QF1, the first rotary switch SB1, and the normally closed contact KA1 of the intermediate relay, which energizes the coil of the AC contactor KM6, thereby causing the main contact 9 of the AC contactor KM to close.

[0048] 3. The platinum resistance thermometer checks the ambient temperature and sends feedback to the temperature controller 15 via a resistor. The temperature controller 15 then uses PID control to output a 12V voltage to the solid-state relay 10, which in turn turns the solid-state relay 10 on.

[0049] 4. The power supply voltage passes through the second miniature circuit breaker QF2, the main contact 9 of the AC contactor KM, and the solid-state relay 10, energizing one heating unit 13 and the other heating unit 13 for heating.

[0050] 5. The temperature controller 15 uses PID control to control the on / off state of the solid-state relay 10, thereby achieving the function of heat preservation.

[0051] In some embodiments, the device further includes an intermediate relay normally open contact 7 and an alarm unit 8, which are connected in series and between the live wire and the neutral wire of the power supply. See [reference needed]. Figure 1 One end of the normally open contact 7 of the intermediate relay is connected to the circuit between the first miniature circuit breaker 1 and the first switch 4. The other end of the normally open contact 7 of the intermediate relay is connected to one end of the alarm unit 8. The other end of the alarm unit 8 is connected to the circuit between the AC contactor coil 6 and the power supply neutral wire. When the temperature detection unit 11 detects that the temperature exceeds the set temperature, the power supply voltage is transmitted through wires to the over-temperature alarm contact of the temperature controller 15, the intermediate relay coil 12, the first miniature circuit breaker 1, the normally open contact 7 of the intermediate relay, and the alarm unit 8, forming an over-temperature alarm system. The alarm unit 8 can be an alarm light.

[0052] The alarm principle of the material mixer heating device in this example is as follows:

[0053] When the temperature detected by the platinum resistance thermometer exceeds the set temperature, the temperature controller 15 cuts off the 12V output, the solid-state relay 10 disconnects, and heating stops. When the temperature detection unit 11 detects that the temperature exceeds the set temperature, the over-temperature alarm contact of the temperature controller 15 closes. The power supply voltage passes through the over-temperature alarm contact of the temperature controller 15 to energize the coil 12 of the intermediate relay KA, thereby closing the normally open contact 7 of the intermediate relay KA. The power supply voltage passes through the first miniature circuit breaker QF1 and the normally open contact 7 of the intermediate relay KA to energize the alarm light L, thus providing an over-temperature alarm.

[0054] The temperature controller 15 includes a first alarm terminal and a second alarm terminal. The device also includes a second switch 17, which is connected in series with an intermediate relay coil 12 and between the live and neutral wires of the power supply. One end of the intermediate relay coil 12 is connected to the first alarm terminal. When the temperature detected by the temperature detection unit 11 exceeds the set temperature, the second switch 17 closes, energizing the intermediate relay coil 12, and triggering the alarm unit 8. The device may also include a third switch 18, which is connected in parallel with the second switch 17 and is connected to the second alarm terminal.

[0055] In this example, the device is started by operating the first switch. The temperature of the heating unit is detected by the temperature detection unit and fed back to the temperature controller for PID regulation. The PID controller is not fixed and can be modified and adjusted according to the actual situation. Except for the heating unit and platinum resistance thermometer, the other electrical components are installed in the control box and arranged and wired in a reasonable manner. The wiring must be secure.

[0056] The advantages of the material mixer heating device in this example are as follows: When the material mixer is turned on, the device is activated. A temperature detection unit collects and feeds back the temperature of the heating unit to the temperature controller. The temperature controller uses a PID control output signal to control the conduction of a solid-state relay. The power supply voltage is then delivered to the heating unit through the solid-state relay, thus achieving the heating effect. Temperature control is achieved by detecting the temperature of the heating unit through the temperature detection unit and the temperature controller. This preheating effect at the end of the material mixer shortens the time required to resume operation after a shutdown, improves work efficiency, reduces labor intensity, and increases equipment utilization. In case of overheating, the heating circuit is disconnected, and an alarm is triggered, thus achieving temperature control.

[0057] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
