Description

Technical Field

[0001] The invention relates to the field of fluid temperature control system technology, and in particular to a constant temperature control device and a constant temperature control method for cooling water in a blow molding workshop. Background Art

[0002] The pipeline thermostatic control device has gradually emerged with the development of industrial automation and temperature control technology. Due to production safety requirements, some industrial production plants need to keep the temperature in the plant at all times to avoid the impact of high or low temperatures on operators and products. As modern industry has higher and higher requirements for temperature control accuracy, traditional temperature control methods can no longer meet production needs.

[0003] Existing temperature control devices usually use real-time screen feedback to let personnel know the specific temperature value, so that they can adjust the temperature control machine to change the temperature in the field. However, the series of operations operated by data feedback personnel to adjust the temperature have a certain delay, resulting in untimely adjustment of the temperature in the field, thus affecting on-site operations. At the same time, when the pipeline fluid is heated, the high-temperature fluid is prone to generate gas, thereby forming bubbles in the pipeline, causing fluid flow to stagnate and affecting the temperature heating operation. Summary of the invention

At the same time, the high-temperature fluid flows along the spiral water groove, thereby separating the gas generated inside, and the opening of the air guide port provides a discharge space for the separated gas, and the gas rises into the air guide port for discharge.

[0010] By adopting the above technical solution, the torsion spring stretches to form elastic force, thereby applying thrust to the boost plate, so that the boost plate drives the stretching shell to move laterally.

At the same time, the limit plate is integrally clamped in the limit groove, and is limited by the two ends of the inner wall of the limit groove to prevent it from slipping out. When the limit plate abuts against the two ends of the inner wall of the limit groove, the water leakage port on the surface of the limit plate discharges a small amount of fluid, which plays a role in mixing temperature, controlling flow and draining water.

[0014] By adopting the above technical solution, the opening of the diversion cavity reserves space for the movement of the force-bearing block. At the same time, the air guide port opened inside the force-bearing block is connected to the air guide channel, thereby providing a discharge path for the transmission of the diverted gas, so that the gas is discharged from the air guide channel into the degassing tank.

[0016] By adopting the above technical solution, the synchronization groove is clamped with the abutment plate. When the clamping plate moves laterally, the synchronization groove drives the force-bearing block to move along the diversion cavity as a whole, thereby providing moving power for the connection between the air guide port and the top opening of the diversion shell, and during the movement of the force-bearing block, the sealing sleeve covers both sides of the force-bearing block to prevent liquid leakage.

When the abutment plate moves laterally, it contacts pressure sensor 1 and pressure sensor 2 to transmit instructions, which is convenient for controlling subsequent heating, cooling and other structures.

[0019] Preferably, a heating mechanism and a cooling mechanism are respectively fixedly arranged on the outer surface of the main shell at the upper and lower ends of the temperature control cavity, the output ends of the heating mechanism and the cooling mechanism both pass through the main shell and are located in the temperature control cavity, and a tortuous protrusion is protruded from the inner wall of the temperature control cavity at the output ends of the heating mechanism and the cooling mechanism.

At the same time, the zigzag protrusion makes the structure in the temperature control chamber curved, thereby increasing the flow distance of the fluid and improving the contact effect between the fluid and the heating mechanism and the cooling mechanism.

[0021] Preferably, the inner wall of the diversion chamber is located on one side of the degassing tank and passes through the main shell to communicate with the outside, and a rotatable interactive door that can be opened and closed is provided at the communication port.

[0022] By adopting the above technical solution, the diversion cavity is connected to the outside, and a movable interactive door is provided at the connecting port, thereby facilitating maintenance and disassembly of the degassing tank by personnel.

[0023] A method for manufacturing a cosmetic bottle by a blow molding device, comprising the following steps: S01. Normal temperature fluid flows into the main shell from the water inlet, and then the fluid enters the temperature control cavity. At this time, the abutment plate is located in the middle of the installation cavity. Part of the fluid flows into the installation cavity from the main channel and is discharged from the water outlet. The remaining fluid is diverted by the diversion port when entering the main channel and flows into the water inlet, and then flows into the diversion shell from the water inlet, and then flows into the water outlet from the diversion shell, and then is introduced into the auxiliary channel, and finally flows into the installation cavity from the auxiliary channel and is introduced into the water outlet and then discharged.

[0024] S02. When the temperature of the fluid is too high, the high-temperature fluid flowing into the secondary channel contacts the heating core to conduct heat energy, making the wax liquid a fluid, thereby expanding the space in the wax cavity, and then causing the extension shell to extend horizontally, pushing the abutment plate to press into the end face of the installation cavity close to the main channel to form a seal, and at the same time, the abutment plate is engaged with the synchronous groove to drive the force block to move synchronously, so that the air guide port is connected with the top opening of the diversion shell; At the same time, the pressing of the abutment plate generates pressure on the pressing end of the pressure sensor 1, so that the pressure sensor 1 controls the refrigeration mechanism to cool the high-temperature fluid. At this time, the main channel is in a closed state, and all high-temperature fluids flow into the water inlet from the diversion port, and then are introduced into the diversion shell and diverted along the spiral water groove. The high-temperature fluid flows along the spiral water groove to separate the hot air, and the separated hot air is discharged from the air guide port into the air guide channel, and then enters the degassing tank for storage; The high-temperature fluid diverted by the spiral water groove is discharged into the secondary channel from the water outlet, and then flows into the installation cavity through the gap of the opening and closing valve and is discharged to the water outlet. The cooled fluid continues to reduce the high temperature applied to the heating core, so that the wax liquid is gradually converted into a solid state, and the torsion spring is extended to drive the extension shell to recover, so that the main channel is adjusted to a connected state, and the pressure on the pressure sensor is cancelled.

[0025] S03. When the fluid temperature is too low, the low-temperature fluid flowing into the auxiliary channel contacts the heating core to conduct low temperature, so that the wax liquid is converted into a solid state, thereby reserving a contraction space in the wax cavity, and then the torsion spring stretches to drive the stretching shell to retract, so that the abutment plate is pressed into the end face of the installation cavity close to the auxiliary channel to form a seal to reduce the fluid flow rate. At the same time, as the low-temperature fluid flows out from the notch of the opening and closing valve, it is introduced into the water leakage port on the surface of the limit plate, and then discharged into the installation cavity and into the water outlet; At the same time, the abutment plate abuts against the end face of the installation cavity, thereby generating pressure on the pressing end of the second pressure sensor, so that the second pressure sensor controls the heating mechanism to heat the low-temperature fluid. Part of the heated fluid flows into the installation cavity from the main channel and mixes with the low-temperature fluid and is discharged to the water outlet end, and the remaining fluid flows into the secondary channel from the diversion port and contacts the heating core, thereby transferring heat energy to heat the wax liquid and convert it into liquid, thereby adjusting the secondary channel to a connected state and canceling the pressure applied to the second pressure sensor.

[0026] In summary, the present invention includes at least one of the following beneficial technical effects: 1. The heating core receives the fluid temperature for conduction, and controls the extension shell to extend and retract according to the high-temperature and low-temperature fluids, thereby driving the abutment plate to move horizontally to open and close the main channel and the auxiliary channel, and in the process of the movement of the abutment plate, it contacts the pressing end of the pressure sensor 1 and the pressure sensor 2 respectively, thereby heating and cooling the temperature of the fluid, so that the fluid always maintains a stable temperature, effectively avoiding the delay of personnel operation adjustment; 2. With the help of high-temperature fluid flowing into the diversion shell and contacting the spiral water groove, during the rotational flow of the high-temperature fluid, the hot air generated by the high temperature of the fluid is dissipated and rises, and then enters the air guide channel from the air guide port, and is discharged into the degassing tank for storage. The separated fluid is discharged from the water outlet to the auxiliary channel to avoid the problem of bubbles generated by the high temperature of the fluid in the pipeline causing blockage, thereby affecting the heating operation.

[0039] Example 2, reference Figures 1 to 9 A method for controlling the constant temperature of cooling water in a blow molding workshop comprises the following steps: S01. Under normal temperature, the fluid flows into the temperature control chamber 3 from the water inlet end 2. When the fluid flows into the main channel 6 from the temperature control chamber 3, it is separated by the diversion port 7. Part of the fluid flows into the installation chamber 36 from the main channel 6, and finally enters the water outlet end 10 from the installation chamber 36 and is discharged. The remaining fluid flows into the installation chamber 36, is input from the water inlet 28, and is discharged from the water outlet end 10 to the auxiliary channel 8. Finally, the fluid flowing into the installation chamber 36 from the auxiliary channel 8 is mixed with the fluid in the main channel 6 and is discharged.

[0040] S02, when the temperature of the fluid is too high, the high-temperature fluid contacts the heating core 13, thereby applying heat to the wax liquid in the wax cavity 18, and the wax liquid is heated and converted into a liquid state. As the wax liquid is converted, a thrust is generated on the extension shell 15, so that the extension shell 15 moves, thereby pushing the abutment plate 20 to be pressed into the main channel 6, so that the main channel 6 is isolated from the installation cavity 36, and the pressure sensor 34 of the abutment plate 20 sends a signal to make the refrigeration mechanism 5 cool down the fluid. When the fluid is cooled, the wax liquid gradually solidifies, so that the main channel 6 and the installation cavity 36 are adjusted to an open state; At the same time, when the high-temperature fluid flows in and the main channel 6 is in a closed state, all the high-temperature fluid flows into the water inlet 28 from the diversion port 7, and then is introduced into the diversion housing 30 and diverted along the spiral water groove 31. The high-temperature fluid flows along the spiral water groove 31 to separate the hot gas, and the separated hot gas is discharged from the air guide port 26 into the air guide channel 25, and then enters the degassing tank 32 for storage; S03. When the fluid temperature is too low, the low-temperature fluid contacts the heating core 13 to conduct low temperature, so that the wax liquid is converted into a solid state, and then the torsion spring 17 stretches to drive the stretching shell 15 to retract, so that the abutment plate 20 is pressed into the installation cavity 36 to form a closed state of the secondary channel 8. At the same time, the secondary channel 8 forms a small flow through the water leakage hole on the surface of the limit plate 19, and the low-temperature fluid is discharged into the installation cavity 36 through the water leakage hole of the limit plate 19, and finally enters the water outlet 10 to mix with the low-temperature fluid in the main channel 6; At the same time, the abutment plate 20 abuts against the end surface of the installation cavity 36 to control the pressure sensor 2 35, so that the heating mechanism 4 heats the low-temperature fluid, and part of the heated fluid flows into the installation cavity 36 from the main channel 6 and is mixed with the low-temperature fluid and discharged to the water outlet 10, and the remaining fluid flows into the secondary channel 8 and contacts the heating core 13, thereby transferring heat energy to heat the wax liquid and convert it into liquid, so that the secondary channel 8 and the installation cavity 36 are restored to a connected state, and the pressure applied to the pressure sensor 2 35 is cancelled.

[0041] The implementation principle of Example 2 is as follows: under normal conditions, the abutment plate 20 is located in the installation cavity 36 and is in a centered state. The fluid is transported to the water inlet end 2 by an external pipeline, and then flows into the temperature control cavity 3 from the water inlet end 2. When the fluid initially flows into the main channel 6, it is separated by the diversion port 7. Part of the fluid is directly transported to the installation cavity 36 from the main channel 6, and then flows into the water outlet end 10 from the installation cavity 36 and is discharged. The remaining part of the fluid flows into the installation cavity 36, is input into the diversion shell 30 from the water inlet 28, and is discharged from the water outlet end 10 to the auxiliary channel 8. Finally, the fluid that flows into the installation cavity 36 from the auxiliary channel 8 is mixed with the fluid in the main channel 6 and is discharged from the water outlet end 10 together.

[0042] When the fluid temperature is too high, the fluid normally flowing into the secondary channel 8 comes into contact with the heating core 13, and the heating core 13 transfers the heat in the fluid to convert the wax liquid in the wax chamber 18 into a liquid state. As the wax liquid is converted, a thrust is generated on the extension shell 15, and the extension shell 15 moves to push the abutment plate 20 into the main channel 6, so that the main channel 6 and the installation chamber 36 are in a closed state, and the pressing of the abutment plate 20 generates pressure on the pressing end of the pressure sensor 34, sending a signal to control the refrigeration mechanism 5 to lower the fluid temperature in the temperature control chamber 3. When the fluid is cooled, the heat conducted by the heating core 13 is reduced, and the wax liquid gradually solidifies. At this time, the torsion spring 17 rebounds, thereby driving the extension shell 15 to be recovered into the opening and closing valve 9, so that the main channel 6 and the installation chamber 36 are adjusted to an open state. When the fluid temperature reaches a constant temperature state, the abutment plate 20 is restored to a centered state in the installation chamber 36.

[0043] At the same time, when the high-temperature fluid flows into the diversion shell 30, the fluid rotates along the spiral water groove 31 and flows downward. During the flow of the fluid, the heat is in an upward state, so it is diverted from the fluid, and the separated fluid is transported to the air guide channel 25 through the air guide port 26, and finally discharged into the degassing tank 32 for storage. Personnel can rotate the interactive door 37 to replace and maintain the degassing tank 32, and the separated fluid is discharged from the water outlet 29 to the secondary channel 8.

[0044] When the temperature of the fluid is too low, the fluid flowing into the auxiliary channel 8 contacts the heating core 13, thereby transferring the temperature and converting the wax liquid in the wax chamber 18 into a solid state. As the wax liquid converts into a solid state, the pressure applied to the torsion spring 17 is canceled, and the torsion spring 17 rebounds the boost plate 16, so that the boost plate 16 pushes the extension shell 15 into the shell of the on-off valve 9, thereby driving the abutment plate 20 to abut against one side of the inner wall of the installation chamber 36, so that the auxiliary channel 8 and the installation chamber 36 are in a closed state. At this time, most of the low-temperature fluid flows from the main channel 6 into the installation chamber 36, and is finally discharged from the water outlet 10; At the same time, as the abutment plate 20 abuts against the inner wall of the installation cavity 36, pressure is applied to the pressure end of the pressure sensor 2 35, and the pressure sensor 2 35 is controlled to transmit a signal, so that the heating mechanism 4 heats the fluid in the temperature control cavity 3. At this time, due to the multiple leaks on the surface of the limit plate 19, a small part of the fluid in the auxiliary channel 8 still flows into the installation cavity 36, so that a small part of the fluid in the temperature control cavity 3 continues to flow into the auxiliary channel 8. As the temperature of the fluid increases, it flows into the auxiliary channel 8 and contacts the heating core 13, thereby conducting heat to cause the extension shell 15 to extend again, so that the abutment plate 20 is restored to the centered state in the installation cavity 36, and the fluid temperature is restored to a constant temperature state.

[0045] The above are only optional embodiments of the present disclosure and are not intended to limit the present disclosure. For those skilled in the art, the present disclosure may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present disclosure shall be included in the protection scope of the present disclosure.

A constant temperature control method for cooling water in a blow molding workshop, applied to a constant temperature control device according to any one of claims 1 to 9, characterized in that: The following steps are involved: S01, the normal temperature fluid flows into the main housing (1) from the water inlet end (2), and then the fluid enters the temperature control chamber (3). At this time, the abutment plate (20) is located in the middle of the installation chamber (36), and part of the fluid flows into the installation chamber (36) from the main channel (6) and is discharged from the water outlet end (10). The remaining fluid is diverted by the diversion port (7) when entering the main channel (6) and flows into the water inlet (28), and then flows into the diversion housing (30) from the water inlet (28), and then flows into the water outlet (29) from the diversion housing (30), and then is introduced into the auxiliary channel (8), and finally flows into the installation chamber (36) from the auxiliary channel (8), and then is introduced into the water outlet end (10) and then discharged; S02. When the temperature of the fluid is too high, the high-temperature fluid flowing into the secondary channel (8) contacts the heating core (13) to transfer heat energy, so that the wax liquid becomes a fluid, thereby expanding the space in the wax cavity (18), and then the extension shell (15) is extended laterally, pushing the abutment plate (20) into the end surface of the installation cavity (36) close to the main channel (6) to form a seal, and at the same time, the abutment plate (20) and the synchronous groove (23) are engaged to drive the force block (22) to move synchronously, so that the air guide port (26) is connected with the top opening of the diversion shell (30); At the same time, the pressing of the abutment plate (20) generates pressure on the pressing end of the pressure sensor 1 (34), so that the pressure sensor 1 (34) controls the refrigeration mechanism (5) to cool the high-temperature fluid. At this time, the main channel (6) is in a closed state, and all high-temperature fluid flows into the water inlet (28) from the diversion port (7), and is then introduced into the diversion shell (30) and diverted along the spiral water groove (31). The high-temperature fluid flows along the spiral water groove (31) to separate the hot air, and the separated hot air is discharged from the air guide port (26) into the air guide channel (25), and then enters the degassing tank (32) for storage; The high-temperature fluid diverted by the spiral water trough (31) is discharged from the water outlet (29) into the secondary channel (8), and then flows into the installation cavity (36) through the gap of the opening and closing valve (9) and is discharged to the water outlet (10). The cooled fluid continues to reduce the high temperature applied to the heating core (13), thereby gradually converting the wax liquid into a solid state, and the torsion spring (17) is extended to drive the extension shell (15) to be recovered, so that the main channel (6) is adjusted to a connected state, and the pressure on the pressure sensor (34) is cancelled; S03. When the temperature of the fluid is too low, the low-temperature fluid flowing into the auxiliary channel (8) contacts the heating core (13) to transfer the low temperature, so that the wax liquid is converted into a solid state, thereby reserving a contraction space in the wax cavity (18), and then the torsion spring (17) stretches to drive the stretching shell (15) to retract, so that the abutment plate (20) is pressed into the end surface of the installation cavity (36) close to the auxiliary channel (8) to form a seal to reduce the fluid flow rate. At the same time, as the low-temperature fluid flows out from the gap of the opening and closing valve (9), it is introduced into the water leakage port on the surface of the limit plate (19), thereby being discharged into the installation cavity (36) and entering the water outlet (10); At the same time, the abutment plate (20) abuts against the end surface of the installation cavity (36), thereby generating pressure on the pressing end of the second pressure sensor (35), so that the second pressure sensor (35) controls the heating mechanism (4) to heat the low-temperature fluid. Part of the heated fluid flows from the main channel (6) into the installation cavity (36) and mixes with the low-temperature fluid and is discharged to the water outlet (10). The remaining fluid flows from the diversion port (7) into the secondary channel (8) and contacts the heating core (13), thereby transferring heat energy to heat the wax liquid and convert it into a liquid state, thereby adjusting the secondary channel (8) to a connected state and canceling the pressure applied to the second pressure sensor (35).
