Problems solved by technology

[0002] At present, in the production of chemical industry, electronic slurry and other industries, during continuous production, materials of corresponding weight are put into the mixing equipment in a certain proportion for production, but during continuous feeding, there will be bridges, accumulation, import and export of materials Factors such as changes in pressure and temperature lead to certain fluctuations in the flow of input materials. As a result, the more input materials, the greater the error in the total proportion of actual materials. For some industries with high requirements, the input ratio of incoming materials is unstable during production, which is extremely large. Reduced mix consistency
[0003] In addition, the methods and deficiencies currently used by enterprises in powder feeding are as follows: 1. Using traditional manual weighing and then feeding directly, the powder in the workshop is flying, the environment is harsh, and it is not good for human health; 2. Some companies use Currently popular feeding system on the market, but it is often necessary to fill the hopper, measure the rated weight, stop feeding, and then start unloading. In order to improve work efficiency, if materials are loaded and loaded at the same time, the weighing module cannot accurately read the data, and continuous loading and unloading while accurate measurement cannot be realized, which cannot meet the requirements of the enterprise

Embodiment 1

[0029] Embodiment 1: a kind of feeding system that further improves the precision of feeding ratio in the continuous production of chemical slurry, such as figure 1 As shown, it includes a control system, a powder metering and feeding device, a twin-screw mixer 3, a liquid delivery pump 4, and a flow meter 5 for measuring the liquid feeding flow and feeding back information to the control system. The powder metering and feeding device There are two (powder metering and feeding device I and powder metering and feeding device II), each powder metering and feeding device is composed of powder feeder 1 and used to weigh the weight inside the powder feeder and send information The weighing module 2 fed back to the control system is composed of the weighing module 2 installed on the powder feeder; the twin-screw mixer 3 is provided with a powder inlet 31 and a liquid inlet 32, and the outlet of the powder feeder 1 is connected to the twin-screw The powder inlet 31 of the mixer 3 is ...

Embodiment 2

[0030] Embodiment 2: A feeding system for further improving the accuracy of feeding proportioning in the continuous production of chemical slurry, its basic structure is the same as that of Embodiment 1, the difference is that it also includes a powder storage device 7, a commutator 8 and Two vacuum feeders 9, the vacuum feeder is installed on the powder feeder 1, the vacuum feeder 9 communicates with the powder storage device 7 through the commutator 8, the vacuum feeder 9 and the commutator 8 are respectively connected with the control system (such as figure 2 , image 3 shown), the commutator in this embodiment is a three-way commutator.

Embodiment 3

[0031] Embodiment 3: a kind of feeding method that further improves the precision of feeding ratio in the continuous production of chemical slurry, adopts the feeding system described in embodiment 1, comprises the following steps:

[0032] (1) Set the ratio of the powder feeding flow rate to the liquid feeding flow rate in the control system;

[0033] (2) The control system controls the powder feeder 1 and the liquid delivery pump 4 of the powder metering and feeding device to feed powder materials and liquid materials into the twin-screw mixer 3 at a constant flow rate for continuous production; two powder feeders Machine 1 switches feeding to ensure continuous feeding of powder materials.

[0034] (3) The control system monitors the liquid feeding flow rate fed back by the flow meter 5 in real time and the weight of the powder material in the powder feeder 1 fed back by the weighing module 2 in real time, and calculates the powder feeding flow rate;

[0035] The calculatio...
