DETAILED DESCRIPTION

[0016] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0017] like Figure 1-3 As shown, a chlorine-free molding oil dechlorination reactor comprises a reaction tank 1, the upper and lower ends of the reaction tank 1 are open, a funnel-shaped partition 2 is arranged inside the reaction tank 1, a through hole is opened in the middle of the partition 2, a first solenoid valve 3 is arranged at the middle through hole of the partition 2, an end cover 4 is arranged at the upper end of the reaction tank 1, at least one feeding port 5 is arranged on the end cover 4, a driving motor 6 is arranged at the upper end of the reaction tank 1, a stirring assembly is arranged at the output end of the driving motor 6, the stirring assembly is located inside the reaction tank 1 and above the partition 2, a standing tank 7 is arranged below the reaction tank 1, and the upper end of the standing tank 7 is open. A water level pipe 8 connected to the standing tank 7 is arranged on one side of the standing tank 7, a discharge pipe 9 is connected to the standing tank 7, a feeding pipe 10 is arranged at one end of the discharge pipe 9, the feeding pipe 10 is arranged vertically, a plurality of second solenoid valves 11 are arranged at intervals on one side of the feeding pipe 10, a filter cover 12 is arranged on one side of the feeding pipe 10, the second solenoid valves 11 are all located inside the filter cover 12, a plurality of indicator rings 13 for indicating each second solenoid valve 11 are arranged on the outer surface of the water level pipe 8, a sewage pipe 14 is arranged at the lower end of the standing tank 7, and a third solenoid valve 15 is arranged on the sewage pipe 14.

[0018] The reaction tank 1 and the end cover 4, and the reaction tank 1 and the standing tank 7 are connected by flanges, which facilitates the disassembly and assembly of the end cover 4, the reaction tank 1, and the standing tank 7; the partition 2 is made of stainless steel and is fixed to the inside of the reaction tank 1 by welding. The partition 2 is arranged near the bottom of the reaction tank 1. When the reaction tank 1 is placed on a plane, the partition 2 inside the reaction tank 1 and the first solenoid valve 3 on the partition 2 will not contact the placement plane, thereby protecting the first solenoid valve 3; the partition 2 is funnel-shaped, which facilitates the conveying of the molding oil that has not been stagnant and settled above the partition 2 to the standing tank 7 below the partition 2 through the first solenoid valve 3 as much as possible, thereby reducing the residual molding oil in the reaction tank 1.

[0019] There are two feeding ports 5 on the end cover 4, one for adding undechlorinated molding oil into the reaction tank 1, and the other feeding port 5 for adding dechlorinating agent into the reaction tank 1, so that the molding oil and dechlorinating agent can be added and added at the same time, improving work efficiency.

[0020] The driving motor 6 can only drive the molding oil in the reaction tank 1 to mix through the stirring component, but cannot drive the molding oil in the standing tank 7 to mix. Therefore, during the mixing process of the upper reaction tank 1 through the stirring component, the molding oil in the standing tank 7 below is allowed to stand and settle, so as to facilitate the subsequent extraction of the clear molding oil from the standing tank 7 after sedimentation.

[0021] The water level tube 8 is used to display the liquid level position of the molding oil in the static tank 7. When the liquid level position exceeds the uppermost indicator ring 13, it indicates that the molding oil in the static tank 7 also submerges the second solenoid valve 11 located at the uppermost position. After the molding oil in the static tank 7 has been statically settled for a certain period of time, the molding oil located at the uppermost layer reaches the extraction standard, and then only the second solenoid valve 11 located at the uppermost position is opened. Through the external pump suction equipment, through the discharge pipe 9 and the feeding pipe 10 and the second solenoid valve 11 located at the uppermost position, all the molding oil that can be extracted by the second solenoid valve 11 located at the uppermost position is extracted. As the liquid level decreases, when the liquid level in the water level tube 8 is between the first indicator ring 13 and the second indicator ring 13, and the molding oil between the first indicator ring 13 and the second indicator ring 13 reaches the extraction standard, only the second second solenoid valve 11 arranged from top to bottom is opened, and then the molding oil between the first indicator ring 13 and the second indicator ring 13 is extracted through the second solenoid valve 11, and the extraction is carried out in sequence.

[0022] The extraction standard of the molding oil can be determined by observing the situation in the water level pipe 8. Since the water level pipe 8 is connected to the molding oil, the situation in the static tank 7 can be accurately displayed. When the molding oil is clear when observed with the naked eye, the molding oil can be extracted.

[0023] The filter cover 12 is used to prevent the sediment from clogging the second solenoid valve 11, and can isolate the sediment outside the filter cover 12. The molding oil is extracted after sedimentation, which can prevent a large amount of sediment from accumulating on the filter cover 12, so as to ensure the subsequent stable extraction of the clarified molding oil. The sediment accumulates at the bottom of the standing tank 7. When the sediment in the standing tank 7 accumulates thicker, first extract as much extractable molding oil in the standing tank 7 as possible, and then open the third solenoid valve 15 to discharge a large amount of sediment to the outside of the standing tank 7 through the drain pipe 14.

[0024] Working principle: Add the undechlorinated molding oil and dechlorination agent into the reaction tank 1, and then drive the stirring assembly through the driving motor 6 to stir for at least 30 minutes. After the stirring is completed, open the first solenoid valve 3, and discharge the liquid in the reaction tank 1 into the standing tank 7 for standing, and then close the first solenoid valve 3. At this time, continue to add the undechlorinated molding oil and dechlorination agent into the reaction tank 1. The stirring speed of the driving motor 6 is not higher than 30r / min to reduce the vibration and reduce the impact on the standing tank 7 to ensure normal sedimentation in the standing tank 7. After a certain period of sedimentation, the clarified molding oil in the standing tank 7 is extracted out in turn by opening the second solenoid valve 11 in turn until the extraction work is completed, and the remaining molding oil and sediment can either be precipitated again with the next molding oil, or be directly discharged from the standing tank 7 through the drain pipe 14 and the third solenoid valve 15.

[0025] Furthermore, a through groove is provided on the outer surface of the standing tank 7, and a transparent observation window 16 is provided at the through groove of the standing tank 7. A bottom plate 17 is provided inside the standing tank 7 and on one side of the observation window 16. The bottom plate 17 is connected to the inner wall of the standing tank 7 by a fixing rod 18. Since the bottom plate 17 is close to the observation window 16, the sedimentation condition in the standing tank 7 can be clearly and accurately seen through the bottom plate 17. Since the sediment is yellowish white, the bottom plate 17 can be coated with black primer to improve the convenience of observing the sedimentation condition.

[0026] Furthermore, there is a gap between the lower end of the bottom plate 17 and the inner bottom surface of the standing tank 7. When the mixture of sediment and molding oil in the standing tank 7 is discharged through the drain pipe 14, the gap between the lower end of the bottom plate 17 and the standing tank 7 can prevent the sediment from accumulating on one side of the bottom plate 17, and the sediment in the standing tank 7 and the remaining molding oil can be smoothly discharged to the outside of the standing tank 7.

[0027] Furthermore, a reaction space is formed above the partition 2 and between the reaction tank 1 and the end cover 4, and a static space is formed below the partition 2 and between the reaction tank 1 and the static tank 7. The volume of the reaction space is smaller than the volume of the static space, so that the molding oil in the reaction space can be completely discharged into the static space, preventing the molding oil in the reaction space from being insufficiently discharged and affecting subsequent feeding.

[0028] Furthermore, the stirring assembly includes a stirring shaft 19 fixedly connected to the output end of the driving motor 6, and a stirring rod 20 is provided on the outer surface of the stirring shaft 19, and thorn rods 21 are evenly provided on the stirring rod 20. The molding oil and the dechlorination agent in the reaction tank 1 can be stirred by the stirring shaft 19 and the stirring rod 20, and the mixing efficiency can be improved by setting the thorn rod 21.

[0029] The device is provided with a reaction tank 1 and a standing tank 7, so that when the molding oil in the reaction tank 1 reacts with the dechlorinating agent, the molding oil in the standing tank 7 that has completed the reaction can be precipitated, so that the stirring and precipitation of the molding oil can be achieved simultaneously, and finally the precipitated molding oil is extracted out, and the unprecipitated molding oil is added back into the standing tank 7, so that the reaction tank 1 will not be occupied for a long time due to precipitation, thereby improving the use efficiency of the reaction tank 1 and achieving good use effect.
