Description

Technical Field

[0001] This utility model relates to the field of tire vulcanization technology, and in particular to a condensation device for a tire vulcanization vacuum system. Background Technology

[0002] Tire vulcanization is a process used in tire manufacturing, which includes two methods: vertical vulcanization and fixed vulcanizing machine vulcanization. During the tire vulcanization process, a tire vulcanization vacuum system is required to create a vacuum.

[0003] In existing tire vulcanizing vacuum systems, the vacuum pump is directly connected to the vacuum tank, which causes all the water vapor and condensate coming out of the vacuum tank to be sucked into the vacuum pump, thus greatly reducing the working efficiency of the vacuum pump. Utility Model Content

[0004] The present invention aims to provide a condensation device for a tire vulcanization vacuum system, which can prevent most of the condensate and water vapor from entering the vacuum pump, thereby improving the working efficiency of the vacuum pump.

[0005] Therefore, the technical solution adopted by this utility model is as follows: a condensation device for a tire vulcanization vacuum system, including a vacuum condensation tank and a control cabinet; a vacuum pump is fixedly connected to the outlet pipeline at the side end of the vacuum condensation tank, and an inclined baffle is fixedly installed inside, the inclined baffle divides the vacuum condensation tank into an upper condensation vacuum zone and a lower condensation water zone, an electric connecting valve is fixedly installed on the vacuum condensation tank, the electric connecting valve connects the bottom end of the condensation vacuum zone and the top end of the condensation water zone, and is electrically connected to the control cabinet.

[0006] As a preferred embodiment of the above scheme, a conveying pipe is fixedly connected to the bottom of the condensate area, an electric drain valve is fixedly installed on the conveying pipe, and the control cabinet is electrically connected to the electric drain valve.

[0007] More preferably, the condensate area is fixedly connected to an air vent valve and a water level gauge, and the control cabinet is electrically connected to the air vent valve and the water level gauge.

[0008] A further preferred embodiment is that a plurality of condensate adsorption baffles are fixedly arranged in the condensation vacuum zone.

[0010] The beneficial effects of this utility model are as follows: by using a vacuum condenser, inclined baffle, and electric connecting valve, water vapor and condensate that are about to enter the vacuum pump can be collected and discharged into the condensate area, preventing most of the condensate and water vapor from entering the vacuum pump, thereby improving the working efficiency of the vacuum pump. Attached Figure Description

[0011] Figure 1This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0012] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0013] like Figure 1 As shown, a condensation device for a tire vulcanization vacuum system includes a vacuum condenser tank 12 and a control cabinet. A vacuum pump 22 is fixedly connected to the outlet pipeline at the side end of the vacuum condenser tank 12, and an inclined baffle 15 is fixedly installed inside, dividing the vacuum condenser tank 12 into an upper condensation vacuum zone 17 and a lower condensate zone 19. An electric connecting valve 16 is fixedly installed on the vacuum condenser tank 12, connecting the bottom end of the condensation vacuum zone 17 and the top end of the condensate zone 19, and is electrically connected to the control cabinet. A delivery pipe 21 is fixedly connected to the bottom end of the condensate zone 19, and an electric drain valve 20 is fixedly installed on the delivery pipe 21. The control cabinet is electrically connected to the electric drain valve 20. An air rupture valve 14 and a water level gauge 18 are fixedly connected to the condensate zone 19, and the control cabinet is electrically connected to the air rupture valve 14 and the water level gauge 18. Multiple condensate adsorption baffles 13 are fixedly installed inside the condensation vacuum zone 17. The multiple condensate adsorption baffles 13 are evenly spaced around the center line of the vacuum condenser tank 12.

[0014] A condensation device for a tire vulcanizing vacuum system is applied to a high-efficiency, safe, and energy-saving vacuum system. Water vapor in the vacuum drain tank 2 of this system enters the vacuum condenser tank 12 through the connecting pipe 11, accompanied by the generation of condensate. This condensate adheres to the inner wall of the vacuum condenser tank 12, the condensate adsorption baffle 13, and the inclined baffle 15. Due to gravity, the condensate collects at the lowest point of the inclined baffle 15 and continuously flows from the condensation vacuum zone 17 into the condensate zone 19 through the opened electric connecting valve 16. When the water level gauge 18 detects a high condensate level, it transmits a signal to the control cabinet. The control cabinet then controls the electric connecting valve 16 to close and the air vent valve 14 to open, causing air to be drawn into the condensate zone 19, eliminating the negative pressure. The control cabinet then controls the electric drain valve 20 to open, and the condensate flows into the open water tank 6 through the delivery pipe 21. When the condensate level drops to a low level, the control cabinet closes the electric drain valve 20 and the air vent valve 14, and opens the electric connecting valve 16, thus completing an automatic drainage process.

[0015] A high-efficiency, safe, and energy-saving vacuum system includes a vacuum main pipe 1, a vacuum drain tank 2, an open water tank 6, a drain pipe 7, a connecting pipe 11, and a condensation device for a tire vulcanizing vacuum system. The vacuum drain tank 2 and the condensation device are both located above the open water tank 6. The vacuum main pipe 1 is fixedly connected to the side of the vacuum drain tank 2. A water outlet pipe 5 is fixedly connected to the bottom of the vacuum drain tank 2, with the bottom end of the water outlet pipe 5 extending into the open water tank 6. The drain pipe 7 is fixedly connected to the upper end of the open water tank 6. The connecting pipe 11 is fixedly connected to the top of the vacuum drain tank 2 and the condensation device for the tire vulcanizing vacuum system. The bottom end of the delivery pipe 21 of the condensation device extends into the open water tank 6. A water inlet pipe 10 is fixedly installed on the open water tank 6, and a water inlet valve 9 is fixedly installed on the water inlet pipe 10. A hot water recovery tank 8 is fixedly connected to the end of the drain pipe 7 furthest from the open water tank 6.

[0016] Before activation, water is injected into the open water tank 6 through the inlet pipe 10 and inlet valve 9 until it reaches the bottom of the left end of the drain pipe 7. Then, the vacuum pump 22 is started. As the vacuum level increases, under the siphon effect, the water in the open water tank 6 will be vacuum-drawn into the vacuum drain tank 2 through the outlet pipe 5. As the vacuum level continues to rise, when the vacuum level reaches the process set value of -38Pa, the water level in the vacuum drain tank 2 will be raised to the maximum water seal height, and the vacuum system can then be put into operation. The hot water drawn from the vacuum main pipe 1 in the production workshop enters the vacuum drain tank 2. Water that is higher than the maximum water seal height will flow downwards through the outlet pipe 5 into the open water tank 6 due to gravity. When there is too much water in the open water tank 6, it can flow into the hot water recovery tank 8 by gravity through the drain pipe 7. According to the on-site vacuum requirement of -37±1Pa, the vacuum drain tank 2 will form two phase zones: the upper drainage vacuum zone 3 and the lower water seal zone 4. The left end outlet of the vacuum main pipe 1 and the connecting pipe 11 are connected to the drainage vacuum zone 3, and the water outlet pipe 5 is connected to the water seal zone 4. The upper limit of the water level in the water seal zone 4 is determined by the vacuum degree of -38Pa, and a height space of 200mm must be left for the water to fall from the vacuum main pipe 1. The lower limit of the water level in the water seal zone 4 is determined by the vacuum degree of -36Pa.

[0017] The diameter of the main vacuum pipe 1 is 219mm-300mm, and the slope is 0.5%-0.7%. This allows water in the lower half of the main vacuum pipe 1 to flow by gravity, while the vapor in the upper half is drawn into the vacuum drain tank 2 by vacuum. Furthermore, because the diameter of the main vacuum pipe 1 is large enough, in addition to its vacuum energy storage function, it also ensures that the negative pressure between the main vacuum pipe 1 and the vacuum drain tank 2 in the workshop remains consistent.

[0018] A negative pressure sensor is fixedly installed inside the tail end of the vacuum main pipe 1. The negative pressure sensor and the vacuum pump 22 are both electrically connected to the control cabinet.

[0019] The negative pressure sensor detects the vacuum level within the main vacuum pipe 1 and transmits a signal to the control cabinet, enabling the control cabinet to control the speed of the vacuum pump 22 and ensure that the vacuum level in the main vacuum pipe 1 of the workshop is maintained between -37±1Pa. The control cabinet panel is set to a vacuum level of -38Pa according to process requirements, and a PID controller is used to perform frequency conversion control on the motor of the vacuum pump 22. To achieve intelligent production, an industrial Internet of Things (IoT) and remote control system can be installed on the vacuum system. The vacuum system can be accessed via the company intranet on an office computer or by logging into an office computer via the internet, enabling real-time monitoring and start / stop control of the vacuum system. The power station does not require on-duty personnel, achieving long-term safe and stable operation of the vacuum system.

[0020] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
