[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-5 , a metering feeding mechanism for cresol production, including a feeding tank 1, on which there are a feed inlet 14 and a discharge outlet 2. It also includes a control mechanism. A second switch 13 is installed at the position of the discharge outlet 2. Above the feeding tank 1, a storage tank is installed. The storage tank is communicated with the feeding tank 1 through the feed inlet 14. The volume of the storage tank can be designed to be larger, storing a large amount of additives at one time, thus reducing the labor cost of continuous feeding. At the feed inlet 14 and the discharge outlet 2, a first solenoid valve 4 and a second solenoid valve 3 are respectively installed. The control mechanism includes a first switch 11 and a second switch 13 that can respectively control the opening and closing of the first solenoid valve 4 and the second solenoid valve 3. It also includes an opening and closing mechanism that controls the opening and closing of the first switch 11 and the second switch 13 through the liquid level height inside the feeding tank 1. The first switch 11 and the second switch 13 are controlled by an electric circuit so that only one of them can be opened at the same time. That is, when the first switch 11 is open, the second switch 13 is in the closed state. The opening and closing mechanism includes a floating block 10, and the floating block 10 can move up and down with the liquid level and respectively contact the first switch 11 and the second switch 13. The buoyancy of the floating block 10 on the liquid surface can push the first switch 11 to close. When the first switch 11 is closed, the second switch 13 is opened at the same time. At this time, the additive will enter the reaction tank that needs to be added through the discharge outlet 2. At this time, the liquid level inside the feeding tank 1 continuously drops. When the floating block 10 separates from the first switch 11, the first switch 11 remains closed and the second switch 13 remains open. When the liquid level continuously drops, the floating block 10 contacts the second switch 13. At this time, the second switch 13 is pushed to close. When the second switch 13 is closed, the first switch 11 is opened at the same time. The additive inside the storage tank enters the feeding tank 1 through the feed inlet 14. In this way, the precise feeding of the additive is realized through circulation, and this method can feed intermittently to disperse the feeding process of the additive. A controller is installed on the feeding tank 1. The controller controls the number of cycles. When the preset number of cycles is reached, the first solenoid valve 4 and the second solenoid valve 3 are controlled to stop working.

[0024] For other specific implementable solutions of the present utility model, as can be seen from the attached drawings, it also includes a metering component. The metering component can control the liquid level height of the feeding tank 1 by adjusting the distance between the first switch 11 and the second switch 13. The metering component includes an adjusting rod 7 that is threadedly engaged with the feeding tank 1, and the first switch 11 is installed at the end of the adjusting rod 7 located inside the feeding tank 1. Adjust the maximum rising height of the floating block 10 according to different requirements to adjust the feeding amount each time. At this time, by rotating the adjusting rod 7, through its threaded engagement with the feeding tank 1, the height change of the first switch 11 is driven, thereby completing the control of the feeding amount, which is convenient for adjustment according to different situations and types of additives, and is convenient and fast.

[0025] For other specific implementable solutions of the present utility model, as can be seen from the attached drawings, the opening and closing mechanism further includes a slide bar 12, and the floating block 10 is slidably mounted on the slide bar 12. The cross-section of the slide bar 12 is polygonal, and the polygonal slider can prevent the floating block 10 from rotating when sliding up and down, ensuring that it can effectively contact the first switch 11 and the second switch 13 after sliding up and down, and improving the stability during the use of the device.

[0026] For other specific implementable solutions of the present utility model, as can be seen from the attached drawings, the metering assembly further includes a measuring scale 9 installed on the top of the feeding tank 1, and a positioning rod 8 is slidably mounted on the measuring scale 9. Workers can quickly adjust the amount of each feeding into the feeding tank 1 through the measuring scale 9, and the positioning rod 8 can more accurately show the numerical value of the liquid volume inside the feeding tank 1 at this time.

[0027] For other specific implementable solutions of the present utility model, as can be seen from the attached drawings, it further includes an air pipe 6, and a filter 5 is installed on the air pipe 6. The air pipe 6 is communicated with the outside, which can ensure the air pressure balance inside the feeding tank 1. At the same time, the filter 5 can filter the volatilized toxic gases to avoid polluting the production workshop.

[0028] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
