The products have excellent mechanical strength, good insulation and high finish. It is widely used in electrical appliances, construction and other fields.

[0003] The existing automatic feeding and metering device for BMC liquid components cannot measure the BMC liquid. It is sometimes fast and sometimes slow, with large fluctuations. When the feeding is small, it is easy to affect the accuracy of the measurement. When the feeding is large, it is easy to damage the meter. There are certain limitations, which brings certain adverse effects to people's use process. In order to solve the shortcomings of the existing technology, we propose an automatic feeding and metering device for BMC liquid components. Utility Model Content

[0011] Beneficial Effects

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. In the utility model, after the BMC liquid is separated in the separation tank, the separated BMC liquid is fed into the buffer tank through the through pipe and then metered by the meter. When the feeding is small, it can be accumulated and stored before flowing through the meter for metering, thereby making the metered feeding stable. When the feeding is too much, the internal storage volume of the separation tank is too much, and the BMC liquid makes the floating block float, driving the plug to float up. During the floating process, the stopper can be used to limit the plug to a certain extent, so that the plug can block the through pipe to stop feeding, and the inflow can be slowed down, thereby buffering, making the metering of the meter stable.

[0014] 2. In the utility model, through the filter assembly, when the BMC liquid enters, the filter screen can filter the BMC liquid. When the filter screen is blocked, the upper end of the filter tank will be blocked, so that the air pressure at the upper end of the filter tank becomes larger, and the alarm sounds an alarm. At this time, the impurities on the filter screen can be cleaned. When the air pressure inside the separation tank is too high, the slider will be pushed to slide. At this time, the force of the spring deformation, when the slider slides to the pressure relief hole, the interior of the separation tank is deflated and decompressed. After the pressure inside the separation tank is restored, the slider is pushed to seal under the elastic action of the spring. BRIEF DESCRIPTION OF THE DRAWINGS

When the feeding is small, it can be accumulated and stored and then flowed through the meter 19 for metering, so that the metered feeding is stable. When the feeding is too much, the internal storage volume of the separation tank 1 is too much, and the BMC liquid makes the floating block 7 float, driving the plug 6 to float. During the floating process, the plug 6 can be limited to a certain extent by the limit plug 4, so that the plug 6 can block the through pipe 3 to stop the feeding, and the inflow can be slowed down, thereby buffering, so that the metering of the meter 19 is stable.

[0025] Working principle and process of this utility model:

[0026] After the BMC liquid is separated in the separation tank 1, the separated BMC liquid is fed into the buffer tank 2 through the through pipe 3 and then measured by the meter 19. When the feeding is small, it can be accumulated and stored before flowing through the meter 19 for metering, so that the metered feeding is stable. When the feeding is too much, the internal storage volume of the separation tank 1 is too much, and the BMC liquid makes the floating block 7 float, driving the plug 6 to float. During the floating process, the plug 6 can be limited to a certain position by the limit plug 4, so that the plug 6 can block the through pipe 3 to stop the feeding, and the inflow can be slowed down, so as to perform buffering, so that the metering of the meter 19 is stable. The filter tank 8 is provided. When the BMC liquid enters, the BMC liquid can be filtered through the provided filter screen 9. When the filter screen 9 is blocked, the upper end of the filter tank 8 will be blocked, so that the air pressure at the upper end of the filter tank 8 becomes larger, so that an alarm is sounded through the provided alarm 10. At this time, impurities on the filter screen 9 can be cleaned. When the air pressure inside the separation tank 1 is too high, the slider 16 will be pushed to slide. At this time, the deformation force of the spring 15, when the slider 16 slides to the pressure relief hole 14, the interior of the separation tank 1 is deflated and decompressed. After the internal pressure of the separation tank 1 is restored, the slider 16 is pushed to seal under the elastic action of the spring 15.
