Multi-batch metering oil injection system and method

Abstract

The invention discloses a multi-batch metering oil injection system and a multi-batch metering oil injection method. The system comprises an oil storage tank, a batch metering balance and an electrical control cabinet, wherein a first oil pump is arranged on a first pipeline for connecting the oil storage tank and the batch metering balance; a second oil pump is arranged on a second pipeline of an internal mixer externally connected to the batch metering balance; the oil storage tank, the first oil pump, the second oil pump and the batch metering balance are electrically connected with the electrical control cabinet respectively; the oil storage tank comprises an inner container and a preheating sleeve; the inner container is arranged in the preheating sleeve; a heat medium is filled between the inner container and the preheating sleeve; the batch metering balance comprises an oil barrel and a weight detector; and the weight detector is arranged at the bottom of the oil barrel. The method comprises the following steps of: under the control of the electrical control cabinet, preheating oil in the oil storage tank by the heat medium; conveying the oil from the first oil pump into the batch metering balance; weighing the oil by the batch metering balance according to weights of corresponding batches; and conveying the weighed oil to the internal mixer through the second oil pump. By the system and the method, the oil can be automatically injected into the internal mixer; the oil injection amount is accurate; and the labor intensity of a user is low.

Description

technical field [0001] The invention relates to the technical field of oil injection for internal mixers, in particular to a multi-batch metered oil injection system and method. Background technique [0002] With the increasingly fierce market competition, in order to improve the core competitiveness of enterprises and make them invincible in the market competition, major manufacturers have gradually implemented quality control and cost control within the enterprise. [0003] In the rubber and plastic modification industry, when the internal mixer is used for the internal mixing process, the same batch of materials often needs to be intermittently injected multiple times in the internal mixer, and the commonly used oiling method still remains at the traditional manual weighing Compared with the method of pouring, this method is simple and easy to implement, but in practice, this method has the following defects: (1) In large-scale industrial production, it is easy to be affe...

[0003] In the rubber and plastic modification industry, when the internal mixer is used for the internal mixing process, the same batch of materials often needs to be intermittently injected multiple times in the internal mixer, and the commonly used oiling method still remains at the traditional manual weighing Compared with the method of pouring, this method is simple and easy to implement, but in practice, this method has the following defects: (1) In large-scale industrial production, it is easy to be affected by operators and cause inaccurate liquid measurement, and batch-to-batch (2) When the internal mixer produces a batch of materials for each machine, it is necessary to manually inject liquid into the internal mixer for multiple batches, which will greatly increase the labor intensity of the employees, especially in mass production. Its labor cost is quite high; (3) In the process of weighing liquid and pouring liquid by manual method, it is easy to cause pollution to the production site, thereby affecting the environment of the entire production site
